According to this configuration, the distribution of the airflow flowing out of the rotary cylinder can be changed by changing the ratio of the airflow flowing into the rotary cylinder. Therefore, the distribution of the material deposited through the opening of the screen portion can be changed to control the basis weight distribution of the manufactured sheet. Also, in the above configuration, the sieve portion may be configured to include: a rotatable drum portion; a housing portion that covers at least a portion of the drum portion where the opening is formed; and a material supply port for containing the above The conveying airflow of the material is supplied to the inside of the drum portion; the first and second suction ports are used to supply air not containing the material from the outside of the housing portion to the inside of the drum portion, And are provided separately in the direction of the rotation axis of the rotating drum; and a position changing part that changes the position of the first suction port relative to the material supply port and the second suction port according to the control of the control part, respectively Relative to the position of the material supply port. According to this configuration, it is possible to change the distribution of the airflow flowing out of the rotating drum portion by changing the distribution of the airflow flowing into the rotating drum portion. Therefore, the distribution of the material deposited through the opening of the screen portion can be changed to control the basis weight distribution of the manufactured sheet. In the above configuration, the control unit may be configured to control the flow rate of the conveying airflow. According to this configuration, by controlling the flow rate of the conveying air flow supplied to the drum portion, the distribution of accumulated materials can be controlled more effectively. In addition, in the above-mentioned configuration, it may be configured to have a suction portion that sucks the material toward the accumulation surface by suction airflow; and the control portion controls the flow rate of the suction airflow. According to this configuration, the distribution of the deposited material can be controlled more effectively by controlling the flow rate of the suction airflow that attracts the material to the accumulation surface.

Hereinafter, a preferred embodiment of the present invention will be described in detail using drawings. In addition, the embodiments described below do not limit the content of the invention described in the scope of patent application. In addition, all the components described below are not essential components of the present invention. [First Embodiment] FIG. 1 is a schematic diagram showing a configuration of a sheet manufacturing apparatus 100 to which a first embodiment of the present invention is applied. The sheet manufacturing apparatus 100 described in this embodiment is more suitable for manufacturing new paper, for example, by dry defibrating and fibrillating waste paper used as raw materials such as confidential paper, and then pressurizing, heating, and cutting.之 装置。 The device. It is also possible to increase the bonding strength or whiteness of paper products according to the application by mixing various additives into the fibrillated raw materials, or to add functions such as color, fragrance and flame retardancy. In addition, by controlling the density, thickness, and shape of the paper and forming it, paper of various thicknesses and sizes, such as A4 or A3 conventional size office paper and business card paper, can be manufactured according to the application. The sheet manufacturing apparatus 100 includes a supply unit 10, a coarse crushing unit 12, a defibrating unit 20, a sorting unit 40, a first mesh forming unit 45, a rotating body 49, a mixing unit 50, a stacking unit 60, and a second mesh The object forming section 70, the conveying section 79, the sheet forming section 80, and the cutting section 90. In addition, the sheet manufacturing apparatus 100 includes a humidifying unit 202, 204, 206, 208, 210, 212 for the purpose of humidifying the raw material and / or humidifying the space where the raw material is moved. The specific configuration of the humidifying sections 202, 204, 206, 208, 210, and 212 is arbitrary, and examples thereof include steam type, gasification type, warm air gasification type, and ultrasonic type. In this embodiment, the humidifiers 202, 204, 206, and 208 are constituted by a humidifier of a vaporization type or a warm air vaporization type. That is, the humidifiers 202, 204, 206, and 208 have filters (not shown) humidified with water, and by passing air through the filters, humidified air with increased humidity is supplied. In addition, the humidifiers 202, 204, 206, and 208 may be provided with heaters (not shown) that effectively increase the humidity of the humidified air. In this embodiment, the humidifier 210 and the humidifier 212 are composed of an ultrasonic humidifier. That is, the humidifiers 210 and 212 have a vibration part (not shown) that atomizes water, and supplies the mist generated by the vibration part. The supply unit 10 supplies the raw material to the coarse crushing unit 12. The material for manufacturing the sheet by the sheet manufacturing apparatus 100 may be any material that contains fibers, and examples thereof include paper, pulp, pulp sheets, non-woven cloth, and woven fabric. In the present embodiment, a configuration in which the sheet manufacturing apparatus 100 uses waste paper as a raw material is exemplified. The supply unit 10 may be configured to include, for example, a stacker that stacks and accumulates waste paper, and an automatic loading device that transports waste paper from the stacker to the coarse crushing unit 12. The coarse crushing portion 12 cuts (coarse crushes) the raw material supplied by the supply portion 10 by the coarse crushing blade 14 into coarse fragments. The coarse crushing blade 14 cuts the raw material in the air such as the atmosphere (in the air). The coarse crushing unit 12 includes, for example, a pair of coarse crushing blades 14 that sandwiches and cuts the raw material; and a drive unit that rotates the coarse crushing blades 14; The shape or size of the coarse fragments is arbitrary, as long as it is suitable for the defibrating process of the defibrating unit 20. For example, the coarse crushing section 12 cuts the raw material into pieces of paper having a square size of 1 to several cm or less. The coarse crushing portion 12 has a barrel (hopper) 9 that receives coarse debris cut by the coarse crushing blade 14 and dropped. The barrel 9 has, for example, a tapered shape whose width gradually narrows in the direction in which coarse debris flows (direction of travel). Therefore, the barrel 9 can catch more coarse debris. A tube 2 communicating with the defibrating unit 20 is connected to the barrel 9. The tube 2 forms a conveying path for conveying the raw material (coarse pieces) cut by the coarse crushing blade 14 to the defibrating unit 20. The coarse chips are collected by the barrel 9 and transferred (conveyed) to the defibrating unit 20 through the tube 2. Humidifying air is supplied from the humidifying section 202 in the vicinity of the cylinder 9 provided in the coarse crushing section 12 or the cylinder 9. Thereby, the phenomenon that the coarse debris cut by the coarse debris blade 14 is attracted to the inner surface of the barrel 9 or the tube 2 due to static electricity can be suppressed. In addition, since the coarse debris cut by the coarse debris blade 14 is transferred to the defibrating unit 20 together with the humidified (high humidity) air, the effect of suppressing adhesion of defibrated objects inside the defibrating unit 20 can also be expected. In addition, the humidifying unit 202 may be configured to supply humidified air to the coarse crushing blade 14 and de-electricize the raw material supplied from the supply unit 10. In addition, a static eliminator may be used together with the humidifier 202 to remove electricity. The defibrating unit 20 defibrates the coarse crushed material cut by the coarse crushing unit 12. More specifically, the defibrating unit 20 defibrates the raw material (coarse pieces) cut by the coarse crushing unit 12 to produce a defibrated material. Here, "defibrillation" means that the raw material (fibrillated material) formed by bonding a plurality of fibers is untwisted fiber by fiber. The defibrating unit 20 also has a function of separating resin particles, ink, toner, impermeable agent, etc. attached to the raw material from the fibers. Those who pass the defibrating unit 20 are referred to as "defibrillators." In addition to the defibrated fiber, the "defibrillator" also contains particles of resin (resin used to bond multiple fibers to each other) separated from the fiber when the fiber is untwisted, or ink, toner, etc. Agent, or anti-seepage agent, paper strength enhancer and other additives. The shape of the untwisted defibrated object is a string or a ribbon. The untwisted defibrillator may not exist in a state of being entangled with other untwisted fibers (independent state), or it may be entangled with other unwound defibrillators in a lump state (forming a so-called "mass" The state of "block" exists. The defibrating unit 20 performs defibrating in a dry manner. Here, the treatment of defibration or the like in air in the atmosphere (in the air) rather than in liquid is called dry type. In this embodiment, it is assumed that the defibrating unit 20 uses an impeller pulverizer. Specifically, the defibrating unit 20 includes a rotor (not shown) rotating at a high speed, and blades (not shown) located on the outer periphery of the rotor. The coarse fragments of the raw material cut by the coarse crushing section 12 are sandwiched between the rotor and the blade of the defibrating section 20 to be defibrated. The defibrating unit 20 generates air flow by the rotation of the rotor. With this air flow, the defibrating unit 20 can suck raw material, that is, coarse debris from the tube 2, and convey the defibrated material to the discharge port 24. The defibrated material is transferred from the discharge port 24 to the tube 3 and transferred to the sorting section 40 via the tube 3. In this way, the defibrated material generated in the defibrating unit 20 is transferred from the defibrating unit 20 to the sorting unit 40 by the airflow generated by the defibrating unit 20. In addition, in this embodiment, the sheet manufacturing apparatus 100 includes a defibrating unit blower 26 that is an airflow generating device, and the defibrated material is conveyed to the sorting unit 40 by the airflow generated by the defibrating unit blower 26. The blower 26 of the defibrating unit is installed in the tube 3, and the defibrating material and air are simultaneously sucked from the defibrating unit 20, and air is sent to the sorting unit 40. The sorting unit 40 has an inlet 42 through which the defibrated material defibrated by the defibrating unit 20 flows into the tube 3 together with the airflow. The sorting unit 40 sorts the defibrated material introduced into the inlet 42 according to the length of the fiber. In detail, the sorting unit 40 sets the defibrating material below the predetermined size in the defibrating material defibrated by the defibrating unit 20 as the first sorting material, and the defibrating material larger than the first sorting material as the first sorting material. 2 Sort the objects and sort them. The first sorter contains fibers or particles, etc., and the second sorter contains, for example, larger fibers, undefibrated sheets (thick fragments that are not sufficiently defibrated), aggregated, or tangled clumps of defibrated fibers Wait. In the present embodiment, the sorting unit 40 has a drum portion 41 (sieve portion) and a housing portion 43 that houses the drum portion 41. The rotating drum portion 41 is a cylindrical screen portion driven by a motor. The rotating drum 41 has a mesh (filter mesh, wire mesh) and functions as a sieve. With this mesh, the drum portion 41 sorts the first sorter that is smaller than the mesh opening (opening) size and the second sorter that is larger than the mesh opening. As the mesh of the drum portion 41, for example, a metal mesh, an expanded metal sheet that stretches a slit-shaped metal sheet, and a punched metal sheet that is equivalent to a hole formed in the metal sheet by a pressing machine can be used. The defibrated material introduced into the introduction port 42 is conveyed to the inside of the drum portion 41 together with the air flow, and the first sorted material falls down from the mesh of the drum portion 41 by the rotation of the drum portion 41. The second sorting substance that cannot pass through the mesh of the drum portion 41 flows by the airflow flowing into the drum portion 41 from the inlet 42, is guided to the discharge port 44, and is sent to the tube 8. The tube 8 connects the inside of the rotating drum 41 and the tube 2. The second sorted material flowing through the tube 8 flows into the tube 2 together with the coarse fragments cut by the coarse crushing part 12 and is guided to the inlet 22 of the defibrating part 20. By this, the second sorting object is returned to the defibrating unit 20 and is defibrated. In addition, the first sorting material sorted by the drum portion 41 is dispersed into the air through the mesh of the drum portion 41, and is directed to the mesh belt of the first mesh forming portion 45 located below the drum portion 41 46 drops. The first mesh forming portion 45 (separation portion) includes a mesh belt 46 (separation belt), a roller shaft 47, and a suction portion (suction mechanism) 48. The mesh belt 46 is a belt in the shape of a ring, suspended on three roller shafts 47, and conveyed in the direction indicated by the arrow in the figure by the rotation of the roller shaft 47. The surface of the mesh belt 46 is composed of a mesh arranged with openings of a specific size. The fine particles passing through the mesh size in the first sorting descended from the sorting section 40 fall below the mesh belt 46, and the fibers that cannot pass through the mesh size accumulate on the mesh belt 46, and together with the mesh belt 46, the arrow V1 Transport direction. The fine particles falling from the mesh belt 46 are relatively small ones or low densities (resin particles, toner, additives, etc.) in the defibration, and are not used for the removal of the sheet S by the sheet manufacturing apparatus 100. The mesh belt 46 moves at a speed V1 in the normal operation of manufacturing the sheet S. The speed V1 is a specific speed set in advance and is controlled by a control unit 150 (FIG. 10) described later. The speed V1 at which the mesh belt 46 moves can be regarded as the transportation speed at which the mesh belt 46 transports the first mesh W1, that is, the transportation speed of the first mesh W1 in the sorting section 40. Here, the normal operation is the operation except for the start control and stop control of the sheet manufacturing apparatus 100 described later, and more specifically refers to the period during which the sheet manufacturing apparatus 100 manufactures the sheet S of a desired quality . Therefore, the defibrated material defibrated by the defibrating unit 20 is sorted into the first sorted material and the second sorted material in the sorting unit 40, and the second sorted material is returned to the defibrating unit 20. In addition, the first mesh forming part 45 removes the removed matter from the first sorted matter. The remainder after removing the removed material from the first sorting material is a material suitable for manufacturing the sheet S, and this material is accumulated on the mesh belt 46 to form the first mesh W1. The suction part 48 sucks air from below the mesh belt 46. The suction part 48 is connected to the dust collecting part 27 (dust collecting device) via the tube 23. The dust collecting part 27 separates the fine particles from the air flow. A collecting blower 28 is provided downstream of the dust collecting part 27, and the collecting blower 28 functions as a dust collecting suction part that sucks air from the dust collecting part 27. In addition, the air discharged by the trap blower 28 is discharged to the outside of the sheet manufacturing apparatus 100 through the tube 29. In this configuration, the dust blower 28 sucks the air from the suction part 48 through the dust collecting part 27. In the suction part 48, the fine particles passing through the mesh of the mesh belt 46 are attracted together with the air, and are transported to the dust collecting part 27 through the tube 23. The dust collecting part 27 separates and accumulates the fine particles passing through the mesh belt 46 from the airflow. Therefore, on the mesh belt 46, the fibers after the removal of the removed material from the first sorting material are accumulated to form the first mesh W1. The suction by the trap blower 28 promotes the formation of the first mesh W1 on the mesh belt 46, and accelerates the removal of the removed matter. Humidification air is supplied to the space including the rotating drum portion 41 through the humidification portion 204. The humidified air humidifies the first sorting material inside the sorting section 40. Thereby, the adhesion of the first sorting substance to the mesh belt 46 due to static electricity can be weakened, and the first sorting substance can be easily peeled off from the mesh belt 46. Furthermore, it is possible to suppress the adhesion of the first sorting substance to the inner wall of the rotating body 49 or the housing portion 43 due to static electricity. In addition, the suction part 48 can effectively suck the removal object. In addition, in the sheet manufacturing apparatus 100, the configuration for sorting and separating the first defibrated material and the second defibrated material is not limited to the sorting portion 40 having the drum portion 41. For example, a structure in which the defibrated material defibrated by the defibrating unit 20 is classified by a classifier may be adopted. As the classifier, for example, a cyclone classifier, an elbow jet classifier, and an Eddie classifier can be used. If such classifiers are used, the first sorter and the second sorter can be sorted and separated. Furthermore, with the above classifier, it is possible to realize the structure of separating and removing the debris contained in the defibration, which is relatively small or has a relatively low density (resin particles, toner, additives, etc.). For example, a configuration may be adopted in which fine particles included in the first sorting substance are removed from the first sorting substance by a classifier. In this case, it may be configured that the second sorting object is returned to, for example, the defibrating unit 20, the removed matter is collected by the dust collecting unit 27, and the first sorting object after the removed matter is removed is sent to the tube 54. In the conveyance path of the mesh belt 46, on the downstream side of the sorting section 40, air containing mist is supplied through the humidifying section 210. The mist of the fine particles of water generated in the humidifying section 210 descends to the first mesh W1 and supplies moisture to the first mesh W1. Thereby, the amount of water contained in the first mesh W1 can be adjusted, and the adsorption of fibers to the mesh belt 46 due to static electricity can be suppressed. The sheet manufacturing apparatus 100 includes a rotating body 49 that divides the first web W1 deposited on the mesh belt 46. The first mesh W1 is peeled off from the mesh belt 46 at the position where the mesh belt 46 is folded back by the roller shaft 47 and is broken by the rotating body 49. The first mesh W1 is a soft material in which fibers are accumulated and has a mesh shape, and the rotating body 49 unravels the fibers of the first mesh W1 and processes it into a state in which the mixing portion 50 described later can easily mix resin. The configuration of the rotating body 49 is arbitrary, but in the present embodiment, it may have a rotating blade shape having a plate-shaped blade and rotating. The rotating body 49 is arranged at a position where the first mesh W1 peeled from the mesh belt 46 contacts the blade. By the rotation of the rotating body 49 (for example, in the direction indicated by the arrow R in the figure), the blade collides with the first web W1 peeled off from the mesh belt 46 and transported to break it, thereby generating a subdivided body P . In addition, the rotating body 49 is preferably provided at a position where the blade of the rotating body 49 does not collide with the mesh belt 46. For example, the distance between the front end of the blade of the rotating body 49 and the mesh belt 46 can be set to 0. 05 mm or more and 0. 5 mm or less, in this case, the first mesh W1 can be effectively broken by the rotating body 49 without damaging the mesh belt 46. The subdivision body P divided by the rotating body 49 descends inside the tube 7 and is transferred (transported) to the mixing section 50 by the air flow flowing inside the tube 7. In addition, humidified air is supplied to the space including the rotating body 49 through the humidifying section 206. Thereby, the phenomenon that the fibers are attracted to the inside of the tube 7 or the blades of the rotating body 49 due to static electricity can be suppressed. In addition, since the air with high humidity is supplied to the mixing section 50 through the tube 7, the influence of static electricity can also be suppressed in the mixing section 50. The mixing unit 50 includes: an additive supply unit 52 that supplies an additive containing a resin; a tube 54 that communicates with the tube 7 and that allows the air flow including the subdivision body P to flow; and a mixing blower 56. The subdivided body P is a fiber obtained by removing the removed matter from the first sorted matter passing through the sorting section 40 as described above. The mixing section 50 mixes the fibers constituting the subdivided body P with additives containing resin. In the mixing unit 50, the air flow is generated by the mixing blower 56, and the tube 54 is conveyed while mixing the subdivision body P with the additives. In addition, the subdivision body P is untwisted during the flow inside the tube 7 and the tube 54 and becomes a finer fibrous shape. The additive supply unit 52 is connected to an additive cassette (not shown) in which the additive is stored, and supplies the additive inside the additive cassette to the tube 54. The additive cassette may be configured to be detachable to the additive supply unit 52. In addition, a configuration may be provided to supplement the additive cartridge. The additive supply unit 52 temporarily stores additives containing fine powder or fine particles inside the additive cartridge. The additive supply part 52 has a discharge part 52 a that conveys the temporarily stored additive to the tube 54. The discharge unit 52a includes a feeder (not shown) that conveys the additive stored in the additive supply unit 52 to the tube 54; and a baffle (not shown) that opens and closes a pipe connecting the feeder and the tube 54. When the baffle is closed, the pipe or opening connecting the discharge portion 52a and the tube 54 is closed, and the supply of the additive from the additive supply portion 52 to the tube 54 is blocked. When the feeder of the discharge part 52a is not in operation, the additive is not supplied to the tube 54 from the discharge part 52a, but there is a negative pressure in the tube 54, etc., even if the feeder of the discharge part 52a stops The possibility of still flowing to the tube 54. Therefore, by closing the discharge portion 52a, the flow of such additives can be surely blocked. The additive supplied by the additive supply unit 52 includes a resin for bonding a plurality of fibers. The resin contained in the additive is a thermoplastic resin or a thermosetting resin, such as AS resin, ABS resin, polypropylene, polyethylene, polyvinyl chloride, polystyrene, acrylic resin, polyester resin, polyethylene terephthalate Ester, polyphenylene ether, polybutylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyether ether ketone, etc. These resins can also be used alone or in appropriate mixtures. That is, the additive may contain a single substance, a mixture, or a plurality of particles composed of various single or plural substances. In addition, the additive may be fibrous or powdery. The resin contained in the additive is melted by heating to bond the plurality of fibers to each other. Therefore, in a state where the resin and the fiber are mixed, and in a state where the resin is not heated to a melting temperature, the fibers do not stick to each other. In addition, the additives supplied by the additive supplying section 52 may include a coloring agent for coloring the fibers or an aggregation for suppressing fiber aggregation or resin aggregation in addition to the resin that binds the fibers, depending on the type of sheet to be manufactured Inhibitor, flame retardant used to make fibers difficult to burn. In addition, the additive that does not contain a coloring agent may be colorless, or a lighter color that appears to be colorless, or may be white. The air flow generated by the mixing blower 56 draws the subdivision P dropped in the tube 7 and the additive supplied by the additive supply unit 52 into the tube 54 and passes through the mixing blower 56. The airflow generated by the mixing blower 56 and / or the rotating parts such as the blades of the mixing blower 56 mix the fibers constituting the subdivision P with the additive, and the mixture (the mixture of the first sorting substance and the additive) It is transferred to the accumulation part 60 through the pipe 54. In addition, the mechanism for mixing the first sorting substance and the additive is not particularly limited, and it may be a stirrer by a blade rotating at a high speed, or a rotator using a container like a V-type mixer. Such a mechanism is provided in front of or behind the mixing blower 56. The accumulation unit 60 accumulates the defibrated material defibrated by the defibration unit 20. More specifically, the accumulation part 60 introduces the mixture passing through the mixing part 50 from the introduction port 62, untangles the entangled defibrated material (fiber), and makes it fall while being dispersed in the air. Furthermore, when the resin of the additive supplied from the additive supply part 52 is fibrous, the accumulation part 60 unwinds the entangled resin. Thereby, the accumulation part 60 can accumulate the mixture in the second mesh forming part 70 with good uniformity. The accumulation portion 60 has a rotating drum portion 61 and a housing portion 63 that houses the rotating drum portion 61. The drum portion 61 is a screen portion of a cylinder that is rotationally driven by a motor. The drum portion 61 has a mesh (filter mesh, wire mesh) and functions as a sieve. With this mesh, the drum portion 61 passes fibers or particles smaller than the mesh opening (opening), and descends from the drum portion 61. The configuration of the reel section 61 is the same as the configuration of the reel section 41, for example. In addition, the "sieve section" of the drum section 61 may not have the function of sorting specific objects. That is, the “screen portion” used as the drum portion 61 means that the screen portion is provided, and the drum portion 61 may lower all the mixture introduced into the drum portion 61. The second mesh forming portion 70 is arranged below the drum portion 61. The second mesh forming portion 70 accumulates the passing material passing through the accumulating portion 60 to form a second mesh W2. The second mesh forming portion 70 includes, for example, a mesh belt 72, a roller shaft 74, and a suction mechanism 76 (suction portion). The accumulation portion 60 and the second mesh forming portion 70 correspond to the mesh forming portion. In addition, the drum portion 61 corresponds to a sieve portion. The mesh belt 72 is a belt in the shape of a ring, suspended on a plurality of roller shafts 74, and is transported in the direction indicated by arrow V2 in the figure by the rotation of the roller shaft 74. The mesh belt 72 is made of, for example, metal, resin, cloth, or non-woven fabric. The surface of the mesh belt 72 is composed of a mesh arranged with openings of a specific size. Among the fibers or particles falling from the rotating drum 61, the fine particles passing through the mesh size fall below the mesh belt 72, and the fibers that cannot pass through the mesh size accumulate on the mesh belt 72 and are transported together with the mesh belt 72 in the direction of the arrow . The mesh belt 72 moves at a specific speed V2 during the normal operation of manufacturing the sheet S. The normal operation is as described above. The moving speed V2 of the mesh belt 72 can be regarded as the speed of conveying the second mesh W2, and the speed V2 can refer to the conveying speed of the second mesh W2 of the mesh belt 72. The mesh of the mesh belt 72 is relatively fine, and it can be set to a size that does not allow most of the fibers or particles descending from the rotating drum 61 to pass through. The suction mechanism 76 is provided below the mesh belt 72 (the side opposite to the accumulation portion 60 side). The suction mechanism 76 is provided with a suction blower 77, and the suction mechanism 76 can generate a downward airflow (airflow from the accumulation portion 60 to the mesh belt 72) by the suction mechanism 76. The mixture dispersed in the air by the accumulation part 60 is sucked onto the mesh belt 72 by the suction mechanism 76. Thereby, the formation of the second mesh W2 on the mesh belt 72 can be promoted, and the discharge speed from the accumulation portion 60 can be accelerated. Furthermore, the suction mechanism 76 can be used to form a downflow in the falling path of the mixture, which can prevent the defibrated material or additives from tangling in the falling. The suction blower 77 can discharge the air sucked from the suction mechanism 76 to the outside of the sheet manufacturing apparatus 100 through a collection filter (not shown). Or, the air sucked by the suction blower 77 may be sent to the dust collecting part 27, and the removed matter contained in the air sucked by the suction mechanism 76 may be collected. In the space including the drum portion 61, humidified air is supplied through the humidified portion 208. The inside of the accumulation part 60 can be humidified by the humidified air to suppress the adhesion of fibers or particles due to static electricity to the outer shell part 63, and the fibers or particles can be accelerated to fall to the mesh belt 72, forming a佳 之 第 2 网 物 W2. As described above, by the step of depositing the material on the mesh belt 72 in the accumulation portion 60 and the second mesh forming portion 70 (the first step), a second state that contains more air and is in a soft expanded state is formed Mesh W2. The second web W2 accumulated on the mesh belt 72 is transported to the sheet forming portion 80. In the conveyance path of the mesh belt 72, on the downstream side of the accumulation part 60, air containing mist is supplied by the humidifying part 212. With this, the mist generated by the humidifying section 212 is supplied to the second mesh W2, and the amount of moisture contained in the second mesh W2 is adjusted. As a result, it is possible to suppress the adsorption of fibers to the mesh belt 72 due to static electricity. The sheet manufacturing apparatus 100 is provided with a conveying section 79 that conveys the second web W2 on the mesh belt 72 to the sheet forming section 80. The transport unit 79 has, for example, a mesh belt 79a, a roller shaft 79b, and a suction mechanism 79c. The suction mechanism 79c includes a blower (not shown), and an upward air flow is generated on the mesh belt 79a by the attraction of the blower. This air flow attracts the second mesh W2, and the second mesh W2 separates from the mesh belt 72 and is attracted to the mesh belt 79a. The mesh belt 79a moves by the rotation of the roller shaft 79b, and conveys the second mesh W2 to the sheet forming portion 80. In this manner, the transport unit 79 realizes a transport step (second step) of peeling off and transporting the second web W2 formed on the mesh tape 72 from the mesh tape 72. The sheet forming section 80 forms the sheet S from the deposits accumulated in the accumulation section 60. More specifically, the sheet forming portion 80 processes the second web W2 (stacked material) accumulated on the mesh belt 72 and conveyed by the conveying portion 79 to form the sheet S (third step). The processing of the sheet forming portion 80 includes pressing and heating the second web W2. In the sheet forming portion 80, by applying a load to the second web W2, the second web W2 is compressed to homogenize its thickness, and the fibers and the fibers and additives included in the second web W2 are improved The tightness. In addition, the sheet forming portion 80 applies heat to the fibers of the defibrating material included in the second web W2 and the additives to bond the plurality of fibers in the mixture to each other via the additives (resin). The sheet forming portion 80 includes a pressing portion 82 that presses the second web W2 and a heating portion 84 that heats the second web W2 that is pressed by the pressing portion 82. The pressing portion 82 is composed of a pair of pressing rollers 85 (pressing rollers), and presses and presses the second web W2 with a specific nip. The thickness of the second mesh W2 is reduced by pressing, and the density of the second mesh W2 is increased. One of the pair of pressing rollers 85 is a driving roller driven by a motor (not shown), and the other is a driven roller. The pressure roller 85 is rotated by the driving force of a motor (not shown), and conveys the second web W2 that has become high-density by pressurization to the heating section 84. The heating unit 84 can be configured using, for example, a heating roller (heater roller), a hot press forming machine, a heating plate, a hot air blower, an infrared heater, and an ignition holder. In this embodiment, the heating section 84 includes a pair of heating rollers 86. The heating roller 86 is heated to a preset temperature by a heater provided inside or outside. One of the pair of heating rollers 86 is a driving roller driven by a motor (not shown), and the other is a driven roller. The heating roller 86 sandwiches the sheet S pressed by the pressing roller 85 and applies heat to form the sheet S. The heating roller 86 is rotated by the driving force of a motor (not shown), and conveys the sheet S to the cutting unit 90. In addition, the number of the pressing rollers 85 provided in the pressing portion 82 and the number of the heating rollers 86 provided in the heating portion 84 are not particularly limited. In addition, in the step of manufacturing the sheet S by the sheet manufacturing apparatus 100, the boundary between the second web W2 and the sheet S is arbitrary. In the present embodiment, in the sheet forming portion 80 formed into the sheet S by processing the second mesh W2, the second mesh W2 is pressed by the pressing portion 82, and further passed by the heating portion 84 The second web heated by the pressing portion 82 is called a sheet S. That is, a sheet S is called a fiber in which fibers are bonded with additives. The sheet S is transported to the cutting unit 90. The cutting section 90 cuts the sheet S formed by the sheet forming section 80. In this embodiment, the cutting section 90 has a first cutting section 92 that cuts the sheet S in a direction crossing the conveying direction of the sheet S (F in the figure); and a second cutting section 94, It cuts the sheet S in a direction parallel to the conveying direction F. The second cutting section 94 cuts, for example, the sheet S passing through the first cutting section 92. With the above, a single sheet S of a specific size is formed. The cut single sheet S is discharged to the discharge section 96. The discharge section 96 includes a tray or a stacker on which sheets S of a specific size are placed. In the above-mentioned configuration, the humidification sections 202, 204, 206, and 208 may be constituted by one vaporization humidifier. In this case, it suffices that the humidified air generated by one humidifier is branched and supplied to the coarse crushing portion 12, the housing portion 43, the tube 7, and the housing portion 63. This configuration can be easily realized by branching a duct (not shown) for supplying humidified air. Of course, the humidifying sections 202, 204, 206, and 208 may be constituted by two or three vaporizing humidifiers. In addition, in the above configuration, the humidifying sections 210 and 212 may be composed of one ultrasonic humidifier, or may be composed of two ultrasonic humidifiers. For example, it may be configured to branch and supply air containing mist generated by one humidifier to the humidifying section 210 and the humidifying section 212. The blower included in the sheet manufacturing apparatus 100 is not limited to the defibrating unit blower 26, the collection blower 28, the mixing blower 56, the suction blower 77, and the intermediate blower. Of course, for example, a blower that assists each of the blowers mentioned above may be installed in the duct. In the above configuration, the raw material is firstly crushed by the crushing unit 12 and the sheet S is manufactured from the crushed material. However, for example, the sheet S may be manufactured using fiber as a raw material. For example, it is also possible to use a fiber equivalent to the defibrated material defibrated by the defibrating unit 20 as a raw material and to be able to put it into the drum 41. In addition, it is possible to use a fiber equivalent to the first sorted material separated from the defibrated material as a raw material and to be capable of being put into the tube 54. In this case, the sheet S can be manufactured by supplying fibers obtained by processing waste paper, pulp, etc. to the sheet manufacturing apparatus 100. FIG. 2 is a perspective view of the appearance of the sheet manufacturing apparatus 100. The sheet manufacturing apparatus 100 has a housing 220 that houses the above-mentioned components. The case 220 has a substantially box shape including a front portion 221 constituting a front surface, a side portion 222 constituting a left and right side surface, a back portion 223 constituting a back surface, and an upper surface portion 224 constituting an upper surface. On the front part 221, the supply part 10 is partially exposed and provided, and at the same time, a display part 160 displaying various information and an opening and closing door 230 are provided. The display unit 160 includes: a display panel 116 (FIG. 9), which can display various kinds of information; and a touch sensor 117 (FIG. 9), which is overlapped with the display panel 116. The display unit 160 displays an image in which icons for operation are arranged, and detects a user's touch operation on the display unit 160, thereby functioning as a user interface of the sheet manufacturing apparatus 100. The opening / closing door 230 is a door that can be opened and closed to expose a cassette for storing additives. FIG. 3 is a perspective view of the main part of the sheet manufacturing apparatus 100, and FIG. 4 is a cross-sectional view of the main part of the sheet manufacturing apparatus 100. 3 and 4 show the configuration of the accumulation portion 60 and the second mesh forming portion 70 in detail. As shown in FIGS. 3 and 4, the drum portion 61 has a hollow cylindrical shape, and can rotate around the rotation axis Q (FIG. 4). A plurality of openings 61a are formed on the outer peripheral surface 61b of the drum portion 61. As the drum portion 61 rotates, the fibers passing through the opening 61a descend and are accumulated on the mesh belt 72 to form a mesh W. Here, the size, shape, and number of openings 61a formed in the drum portion 61 are not particularly limited. For convenience, in FIGS. 3 and 4, the opening 61 a is enlarged and shown with respect to the drum portion 61. The housing portion 63 covers at least the portion of the drum portion 61 where the opening 61a is formed (the outer peripheral surface 61b where the opening 61a is formed) via the gap. In the example shown in FIGS. 3 and 4, the housing portion 63 includes an opposing wall portion 66 having an inner surface opposed to the outer peripheral surface 61 b, and a right side wall 64 and a left side wall 65, and accommodates the rotating drum portion 61. The right side wall 64 and the left side wall 65 of the housing portion 63 are connected to the opposing wall portion 66 and cover the drum portion 61 from the direction of the rotation axis Q (the direction in which the rotation axis Q extends). Here, regarding the configurations of the accumulation portion 60 and the second mesh forming portion 70, the rotation axis Q direction is the left-right direction, the symbol R indicates the right direction, and the symbol L indicates the left direction. The conveying direction F, the right direction R, and the left direction L are in-plane directions of the second mesh W2 or parallel to the plane of the second mesh W2. The rotation axis Q direction, that is, the RL direction is a direction orthogonal to the transport direction F, and corresponds to the width direction of the second web W2 and the sheet S. Therefore, in the following description, the RL direction is referred to as the width direction WD. In addition, the direction orthogonal to the plane including the width direction WD and the transport direction F is referred to as an up-down direction, and the upward direction is indicated by symbol U, and the downward direction is indicated by symbol D. On the inner surface of the right side wall 64 and the left side wall 65 of the housing portion 63, as shown in FIG. 4, a recess 68 is provided. A pile seal 69a is provided in the recess 68. The rotating drum portion 61 is rotatably supported at a specific interval from the housing portion 63 via a pile seal 69a. The pile seal 69a is composed of, for example, a brush (bristles) in which fine hairs are densely planted on the surface of the base. On the other hand, air including the material is supplied to the accumulation portion 60 through the tube 54 (material supply tube). The pipe 54 has a structure in which one main pipe 54a connected to the mixing blower 56 is branched into branch pipes 54c and 54d in the branch portion 54b. The branch pipe 54c is connected to the air supply pipe 57a, and the branch pipe 54d is connected to the air supply pipe 57b. The main pipe 54a corresponds to the first supply pipe, the branch pipe 54c corresponds to the second supply pipe, and the branch pipe 54d corresponds to the third supply pipe. The mixing blower 56 conveys the air flow M1 containing the material-containing air through the main pipe 54a. The conveying airflow M1 is divided into the branching portion 54b into the conveying airflow M2 flowing through the branching pipe 54c and the conveying airflow M3 flowing through the branching pipe 54d. Here, the material includes the fiber (the first sorted product) separated by the sorting unit 40 as described above and the additive (resin) supplied by the additive supply unit 52, which is a mixture of the fiber and the resin. In addition, the right side wall 64 and the left side wall 65 of the housing portion 63 are respectively connected with air supply pipes 57 a and 57 b for supplying the air containing the material to the inside of the drum portion 61. The air supply pipe 57a penetrates the right side wall 64 and communicates with the inside of the rotating drum 61. That is, a material supply port 64a that opens to the inner space of the drum portion 61 is provided inside the housing portion 63. Similarly, the air supply pipe 57b penetrates the left side wall 65 and communicates with the inside of the rotating drum 61. The left side wall 65 is provided with a material supply port 65a that opens to the inner space of the drum portion 61. The conveyance airflow M2 flows into the drum 61 from the branch pipe 54c through the air supply pipe 57a. Moreover, the conveyance airflow M3 flows into the inside of the drum part 61 from the branch pipe 54d through the air supply pipe 57b. The materials included in the conveying airflows M2 and M3 flow into the drum portion 61 in a state of being humidified by the humidified air supplied from the humidifying portion 206. The air supply pipes 57a and 57b penetrate the right side wall 64 and the left side wall 65, respectively. Inside the drum portion 61, an air flow (conveying air flows M2, M3) containing materials flows in from the air supply pipes 57a, 57b through the material supply ports 64a, 65a in the direction of the rotation axis Q. As shown in FIG. 4, when viewed from the rotation axis Q direction, the material supply port 64 a is provided at a position overlapping the rotation axis Q. The material supply port 65a is also provided at a position overlapping the rotation axis Q. In addition, the housing portion 63 is provided with suction ports 501 and 502 for supplying air not containing material (for example, outside air of the housing portion 63) from the rotation axis Q direction of the rotating drum portion 61 into the rotating drum portion 61. The intake port 501 is a through hole extending in the direction of the rotation axis Q, and formed through the right side wall 64. The intake port 502 is a through hole extending in the direction of the rotation axis Q, and formed through the left side wall 65. Therefore, through the intake ports 501 and 502, the internal space of the housing portion 63 communicates with the outside of the housing portion 63. One of the intake ports 501 and 502 corresponds to the first intake port, and the other corresponds to the second intake port. A partition wall (not shown) can surround the accumulation portion 60 and supply humidified air A1 to the space surrounded by the partition wall (the space where the accumulation portion 60 exists) to make the space a humidification space. The humidified air A1 is air that does not contain materials. The humidified air A1 is supplied to the humidification space by the blower provided in the humidification section 208 or the blower connected to the humidification section 208. The suction port 501 is provided separately from the material supply port 64a, and the suction port 502 is provided separately from the material supply port 65a. In addition, as shown in FIG. 4, when viewed from the rotation axis Q direction, the intake ports 501 and 502 are provided at positions overlapping with the inside of the drum 61. In the configuration example shown in FIGS. 3 and 4, the suction ports 501 and 502 are provided, for example, closer to the mesh belt 72 side (position closer to the mesh belt 72) than the material supply ports 64 a and 65 a. That is, the distance between the suction ports 501 and 502 and the mesh belt 72 is smaller than the distance between the material supply ports 64a and 65a and the mesh belt 72. On the other hand, a mesh belt 72 is arranged below the casing 63. The mesh belt 72 constitutes the lower surface of the housing portion 63, and protrudes outside the housing portion 63 through an opening 63a formed in the lower portion of the housing portion 63. On the upper surface of the mesh belt 72, that is, the accumulation surface 72a, the material descending from the rotating drum portion 61 is accumulated. As described above, the suction mechanism 76 is arranged below the mesh belt 72, and the mesh belt 72 sucks downward. That is, the suction airflow M4 is generated by the suction blower 77 included in the suction mechanism 76. As a result, a downflow DF flowing downward in the direction D is generated inside the housing 63. In this way, in the internal space of the housing portion 63, the conveying airflows M2 and M3 flow into the drum portion 61, and on the other hand, the suction mechanism 76 sucks from below. Therefore, a downflow DF from the inside of the rotating drum portion 61 toward the mesh belt 72 is generated, and with this downflow DF, the material descends toward the accumulation surface 72a through the opening 61a. In addition, when the amount of air sucked by the suction mechanism 76 is greater than the amount of air flowing into the drum portion 61 from the material supply ports 64a, 65a, the difference in the amount of air causes the outside air O1, O2 to flow in from the suction ports 501, 502 . The outside air O1, O2 flows into the inside of the rotating drum portion 61 as shown by arrows in FIG. 4 and becomes part of the downflow DF. In addition, as described above, when the space including the accumulation portion 60 is humidified, the outside air O1 and O2 flowing into the inside of the drum portion 61 become humidified air A1. When the air volume sucked by the suction mechanism 76 is set as the first air volume and the air volume of the conveying airflows M2 and M3 flowing into the drum portion 61 is set as the second air volume, the air intake ports 501 and 502 correspond to the first air volume and The difference in air volume allows external gases O1 and O2 to pass. Therefore, by forming the intake ports 501 and 502, the first air volume and the second air volume can be adjusted or controlled independently. In addition, if the first air volume is greater than the second air volume, there is no possibility that the material leaks from the intake ports 501 and 502 to the outside. In addition, a pile seal 69b is disposed between the outer shell portion 63 and the mesh belt 72. The pile seal 69b has, for example, a rectangular parallelepiped (substantially rectangular parallelepiped) shape, and is composed of, for example, a brush (bristles) in which fine hairs are densely planted on the surface of the base. Since the pile seal 69b is disposed between the right side wall 64 and the left side wall 65 and the mesh belt 72, leakage of the defibrated material from the gap between the outer shell portion 63 and the mesh belt 72 can be suppressed. In addition, in the sheet manufacturing apparatus 100 of the present embodiment, the air intake restricting portion 511 is disposed at the air intake port 501, and the air intake restricting portion 512 is disposed at the air intake port 502. Since the intake restriction portions 511 and 512 have a common structure, the intake restriction portion 512 will be described with reference to FIG. 3. The intake restriction portion 512 has a restriction plate 512a slidably disposed along the left side wall 65 on the outer surface of the left side wall 65, and a plate driving portion 512b that moves the restriction plate 512a. The restricting plate 512a can slide and move between a position where the suction port 502 opening toward the left side wall 65 is blocked and a position where the suction port 502 is not blocked. Therefore, by moving the restricting plate 512a, the opening area of the intake port 502 outside the housing portion 63 can be changed. The plate driving section 512b includes an actuator and the like, and operates according to the control of the control device 110 to move the restriction plate 512a. The control device 110 can adjust the position of the restricting plate 512a by the control board driving portion 512b, and can adjust the opening area of the air inlet 502. The inhalation restricting portions 511 and 512 correspond to the second adjusting portion. The intake restriction portion 511 disposed at the intake port 501 includes a restriction plate 511a that changes the opening area of the intake port 501 at a position where the intake port 501 is closed and a position where the intake port 501 is opened Sliding movement between; and the plate driving portion 511b, which moves the restricting plate 511a. The board driving unit 511b includes an actuator and the like in the same manner as the board driving unit 512b, and operates according to the control of the control device 110 to move the restricting board 511a. The control device 110 can adjust the opening area of the intake port 501 that opens to the outside of the right side wall 64 by the control board driving portion 511b. The air volume of the outside air flowing in from the air intake ports 501 and 502 is determined by the difference between the first air volume and the second air volume described above. Therefore, when the opening area of the intake port 501 located on the right side wall 64 is reduced by the restricting plate 511a, the ventilation resistance to the outside air O1 flowing in from the intake port 501 increases. Along with this, the air volume of the outside air O1 flowing from the suction port 501 to the drum portion 61 decreases, and accordingly, the air volume of the outside air O2 flowing from the suction port 502 increases. Conversely, when the opening area of the intake port 502 on the left side wall 65 is reduced by the restricting plate 512a, the ventilation resistance to the outside air O2 flowing in from the intake port 502 increases. Along with this, the air volume of the outside air O2 flowing into the drum portion 61 from the suction port 502 decreases, and accordingly, the air volume of the outside air O1 flowing from the suction port 501 increases. In addition, in a state where the opening areas of the suction ports 501 and 502 are equal, the air volume of the external air O1 and the air volume of the external air O2 are balanced. The control device 110 can control the operation of the board driving parts 511b and 512b, respectively. Therefore, the balance of the air volume of the external air O1, O2 flowing into the drum portion 61 can be changed by the control of the control device 110. In addition, when the opening area of the suction ports 501 and 502 is very small, and the suction force of the suction mechanism 76 is weak, the total outside air O1 and outside air O2 may be caused by the positions of the restricting plates 511a and 512a. The amount of wind gained was reduced overall. FIG. 5 is an enlarged view of a main part of the sheet manufacturing apparatus 100, and particularly an enlarged front view of the display tube 54 and the airflow restricting portion 401. 6 is a cross-sectional view taken along line AA of FIG. 5. As described above, the airflow restricting portion 401 is disposed above the branch portion 54b of the tube 54. The airflow restricting portion 401 includes: an airflow restricting plate 402 that can slide in the direction indicated by the symbol SD in the figure; and a plate driving portion 403 that moves the airflow restricting plate 402. The position of the airflow restricting portion 401 is preferably in the vicinity of the branch portion 54b, and is more preferably provided in the state before the branch portion 54b branches, that is, the main pipe 54a. In addition, it is preferable that the airflow restricting portion 401 approaches the branch portion 54b in the main pipe 54a. The airflow restricting plate 402 is configured to slide across the main pipe 54a (along a cross section), and a part or all of the main pipe 54a is covered by the airflow restricting plate 402. The cross-sectional area through which the airflow M1 can be conveyed in the inside of the main pipe 54a changes according to the position of the airflow restricting plate 402. The plate driving section 403 includes an actuator and the like, and slides the airflow restricting plate 402 under the control of the control device 110. FIG. 6 shows the relationship between the sliding range of the airflow restricting plate 402 and the cross section of the main pipe 54a. The airflow restricting plate 402 does not overlap the cross-sectional opening of the main pipe 54a in the case where the airflow restricting plate 402 is located at the end in the right direction R side of the movement range SD and the case at the end portion in the left direction L side. At this position, the airflow restricting plate 402 does not affect the transport airflow M1 flowing in the main pipe 54a. When the airflow restricting plate 402 is moved in the movement range SD, the rightward R side or the leftward L side of the cross section of the main pipe 54a is blocked by the airflow restricting plate 402 by the position of the airflow restricting plate 402. Therefore, the airflow restricting plate 402 can affect the transport airflow M1 flowing in the main pipe 54a. Specifically, when the airflow restricting plate 402 is partially overlapped with a part of the right side R side of the cross section of the main pipe 54a, it is more than the center of the main pipe 54a (the position of the branch 54b shown in FIG. 6) On the right side R side, the flow path of the conveying air flow M1 becomes narrower. That is, inside the main pipe 54a, a ventilation resistance is generated on the right direction R side. In this state, since the conveying airflow M1 collides with the airflow restricting plate 402 and flows around the airflow restricting plate 402, the material contained in the conveying airflow M1 flows toward the left side L side. Inside the main pipe 54a, the material is transferred to the left direction L side, and in the branch portion 54b, more material flows in the transfer airflow M3 than in the transfer airflow M2. Therefore, more material flows into the drum portion 61 from the left direction L side than the right direction R side. On the other hand, when the airflow restricting plate 402 is positioned on the left side L side of the cross section of the main pipe 54a, since the cross sectional area (opening area) of the left side L side of the main pipe 54a is reduced, the material contained in the conveying airflow M1 is deflected Flow in the right direction R side. Therefore, the conveying air flow M2 conveys more material than the conveying air flow M3, and more material flows into the drum portion 61 from the right side wall 64 side than the left side wall 65 side. In addition, except for the case where the airflow restricting plate 402 completely closes the cross-sectional opening of the main pipe 54a, the airflow restricting plate 402 has an influence on the flow velocity of the conveying airflow M1, but has a slight influence on the air volume, so it flows into the drum 61 for conveying The sum of the air volume of the air flows M2 and M3 is almost unchanged. However, when the mixing blower 56 that generates the conveying airflow M1 has a weak wind force and the cross-sectional area of the main pipe 54a has a large proportion of the area reduced by the airflow restricting plate 402, a reduction in airflow may occur. In the accumulation section 60, by controlling the plate driving sections 511b and 512b of the intake restriction sections 511 and 512, the balance (left-right balance) of the external air O1 and O2 flowing into the drum section 61 can be adjusted and adjusted. Moreover, by controlling the plate driving part 403 of the airflow restricting part 401, the amount of material transported to the drum 61 by the airflow M2 and the amount of material transported to the drum 61 by the airflow M3 can be balanced ( Balance adjustment). The sheet manufacturing apparatus 100 can make the basis weight of the sheet S manufactured by the sheet manufacturing apparatus 100 uneven in the width direction WD. Generally, the basis weight is used as the quality standard in various papers and sheets including PPC (Plain Paper Copy) paper used in offices. Basis weight is one of the indicators or benchmarks that represent the properties of paper or sheet, and is generally used in the paper industry or printing industry. The basis weight is the weight per unit area of paper or sheet, generally g (g) / m ² (Square meters) as a unit. usually, Based on the premise that the basis weight of the entire paper or sheet is uniform, One basis weight is displayed for one type of paper or sheet. Compared to this, The sheet manufacturing apparatus 100 can manufacture sheets S having basis weight differences in the plane, In this embodiment, An example in which the basis weight varies in the width direction WD of the sheet S will be described. When the direction crossing the conveying direction F (for example, the width direction WD) is the short side direction of the sheet S cut by the cutting section 90, The sheet S after cutting is fixed to the base body in the longitudinal direction, There is a difference (unevenness) in the basis weight in the width direction. E.g, Increase the basis weight of the central part in the width direction, And when the basis weight of the end is reduced compared to the central part, The sheet S has the characteristics of elasticity and toughness at the upper part of the center. E.g, When the sheet S is transported in a printing device such as a printer or a scanner, Due to the elasticity of the waist, it is not easy to cause jams (paper jams) and other transport defects. And better characteristics with good transportability can be obtained. The sheet manufacturing apparatus 100 is provided with a basis weight sensor 309 in order to control the distribution of basis weight. The basis weight sensor 309 is a sensor that detects the basis weight of the second web W2 or the sheet S. The basis weight sensor 309 may be provided at any place after the step of forming the second mesh W2 in the second mesh forming portion 70, However, in this embodiment, The conveyance path of the sheet S is provided between the sheet forming portion 80 and the cutting portion 90. 7 and 8 are explanatory diagrams showing the detection of the basis weight of the sheet manufacturing apparatus 100. 7 is a plan view showing the configuration state of the thickness sensor, Fig. 8 is a graph showing the basis weight distribution of the second network. As shown in Figure 7, In this embodiment, The basis weight sensor 309 (detection section) includes: The first detection unit 309a, The second detection unit 309b, The third detection unit 309c. The first detection unit 309a, The second detection unit 309b, And the third detection unit 309c is arranged in the width direction WD with respect to the conveyance path of the sheet S, And detect the basis weight of the sheet S directly below. The first detection unit 309a, The second detection unit 309b, And the third detection unit 309c is, for example, a reflective photo sensor, With a light source that emits light to the sheet S, And the light-receiving portion that receives the reflected light of the sheet S, And output the output value corresponding to the received light amount. The first detection portion 309a is arranged at the central portion of the sheet S in the width direction WD, The second detection unit 309b is disposed at the end of the sheet S on the left side L side, The third detection portion 309c is arranged at the end portion in the right direction R side of the width direction WD. Here, The symbol WS1 represents the central portion of the sheet S in the width direction WD, Let the symbol WS2 denote the end of the L side in the left direction, The end of the R side in the right direction is indicated by the symbol WS3. The output value of the first detection unit 309a indicates the basis weight of the central part WS1, The output value of the second detection unit 309b indicates the basis weight of the end WS2, The output value of the third detection unit 309c indicates the basis weight of the end WS3. The control device 110 connected to the basis weight sensor 309 may be based on the output value of the basis weight sensor 309, Find the central part WS1 and end WS2 of the sheet S, The basis of WS3. The basis weight sensor 309 is as long as it is connected to the first detection unit 309a, The second detection unit 309b, The configuration of detecting the basis weight of the sheet S at the same position as the third detection unit 309c may be E.g, Transmissive light sensors can also be used. also, The number of detection parts in the width direction WD is not limited to 3 parts, The basis weight can also be detected in more locations. also, In the state before pressurizing and heating the sheet forming portion 80, That is, when the second web W2 is detected, It can also replace the sensor for detecting basis weight, Instead, use a sensor to detect thickness. E.g, It can be set as a sensor to detect the thickness in contact with the second mesh W2, The sensor is configured to detect a plurality of parts in the width direction WD. Since the basis weight of the second mesh W2 is determined by the thickness of the material deposited on the mesh belt 72, Therefore, when measuring the thickness of the second mesh W2, The measured thickness can be converted into basis weight. also, When the second web W2 is pressed and heated to form the shape of the sheet S, There are also cases where the basis weight and thickness are not sufficiently correlated. therefore, Downstream of the sheet forming section 80, More specifically, when the basis weight is detected further downstream than the pressurizing section 82, Preferably like the basis weight sensor 309, It is assumed that the basis weight is detected using a photo sensor or the like. FIG. 8 shows an example of the basis weight distribution of the sheet S detected by the control device 110 based on the output value of the basis weight sensor 309. In the chart of Figure 8, The horizontal axis represents the position of the width direction WD, The vertical axis represents the basis weight. another, When detecting the thickness of the second mesh W2 instead of the basis weight sensor 309, The vertical axis can also be replaced by the thickness. By the control of the control device 110, The sheet manufacturing apparatus 100 is shown in FIG. 8, for example, It can be manufactured with a larger base weight in the center of the WD in the width direction. In addition, the sheet materials S with a smaller basis weight at the ends of the right R side and the left L side are compared. Here, The direction in which the basis weight distribution of the sheet S is different may be a specific direction crossing the second web W2 and the transport direction F of the sheet S, It is not limited to the width direction WD orthogonal to the conveyance direction F. The advantages when manufacturing such a sheet S will be described. The above-mentioned sheet S can be used as a device for conveying the sheet S such as a printer or a scanner. Especially in a device having a mechanism that grips and transports the sheet S by a pair of transport rollers, This is useful in the case where the conveying direction of the sheet S conveyed by the device is a direction crossing the specific direction of the sheet S (in this embodiment, the width direction WD). In this case, The sheet S is the strong waist of the device in the transport direction, Good transportability. also, The sheet S exerts the strength of the waist corresponding to the basis weight of the central part, However, since the basis weight of the end is less than the center, Therefore, the overall basis weight of the sheet S can be suppressed. therefore, The sheet S has strong waist or conveyability, And because of the advantages of small basis weight and light weight. also, Compared with the case of increasing the overall basis weight of the sheet S, There is an advantage in that the amount of materials required for manufacturing the sheet S is reduced. also, The distribution of the basis weight of the sheet S in a specific direction is different, However, it is also possible to pressurize and heat the sheet forming portion 80, The thickness of the end portion in a specific direction is equal to the thickness of the central portion. In this case, The sheet S has a strong waist and excellent transportability due to the distribution of the basis weight. And there is no advantage of uneven thickness. another, Equal thickness is not limited to the same situation, It also includes situations with errors, As long as it is substantially the same. 9 is a block diagram showing the configuration of the control system of the sheet manufacturing apparatus 100.

With this, The desired basis weight distribution can be achieved in the sheet S. E.g, It is possible to increase the basis weight of the center portion than the end portion in a specific direction (eg, width direction WD) in the plane of the sheet S, And making the waist strong in a certain direction, In addition, the sheet S with high transportability when transported by a printer or the like. The drum 61 is configured to be rotatable, In addition, a tube 54 for supplying the conveying airflow M1 containing the material to the inside of the rotary drum 61 is arranged in the rotary drum 61. The tube 54 has a supervisor 54a, Branch pipe 54c, And branch pipe 54d. The branch pipe 54c branches from the main pipe 54a to the branch pipe 54b, It is connected to the end of one side of the rotating cylinder 61 in the direction of the rotation axis. The branch pipe 54d branches from the main pipe 54a to the branch pipe 54b, It is connected to the other end of the rotating cylinder 61 in the direction of the rotation axis. also, Equipped with air flow restrictor 401, It is installed near the branch pipe 54b, In addition, it is used to change the ratio of the transport amount of the material of the transport airflow M2 flowing in the branch pipe 54c to the transport amount of the material of the transport airflow M3 flowing in the branch pipe 54d under the control of the control unit 150. With this, It is possible to change the ratio of the material transfer amount of the conveying air flow M2 feeding the material from one side to the drum part 61 to the material conveying amount of the conveying air flow M3 supplied from the other side The ratio of the material supplied to the drum 61 is changed. therefore, The distribution of the material accumulated through the opening 61a of the drum portion 61 can be changed, The basis weight distribution of the manufactured sheet S is controlled. also, The reel section 61 includes: Shell part 63, It covers the portion of the drum portion 61 where at least the opening 61a is formed; And material supply port 64a, 65a, It is for supplying the conveyance airflow M1 containing the material to the inside of the drum 61. The drum portion 61 includes an intake port 501 and an intake port 502, It is used to convert the air that does not contain materials, that is, the external air O1 O2 is an intake port that is supplied from the outside of the casing 63 to the inside of the drum 61 Moreover, it is provided separately in the direction of the rotation axis of the rotating drum 61. also, Equipped with a self-inspiratory port 501 that can be changed by the control of the control unit 150, Inhalation restricting portion 511 of the ratio of the flow rate of the air supplied by 502, 512. According to this constitution, By changing the ratio of the outside air O1 and the outside air O2 flowing into the drum 61, The distribution of the airflow flowing out of the rotating drum 61 is changed. therefore, The distribution of the width direction WD of the material accumulated through the opening 61a of the drum portion 61 can be changed, The basis weight distribution of the manufactured sheet S is controlled. also, The control unit 150 can control the flow rate of the conveying air flow M1. E.g, The control part 150 can control the air supply volume of the hybrid blower 56, And control the transport airflow M1 M2, M3 wind volume. In this case, The distribution of the material deposited on the accumulation surface 72a can be controlled more effectively. also, The control unit 150 can control the flow rate of the suction airflow M4. E.g, The control part 150 can control the air supply volume of the suction blower 77, And control the air volume of the suction air flow M4. In this case, The distribution of the material deposited on the accumulation surface 72a can be controlled more effectively. The sheet manufacturing apparatus 100 includes: The second mesh forming portion 70, It accumulates materials containing fibers on the accumulation surface 72a to form a second mesh W2; And sheet forming section 80, It processes the second web W2 to form the sheet S. also, have: Operation detection section 153, It serves as the acceptance unit that accepts the setting of the basis weight distribution of the sheet S; And control department 150, It is based on the basis weight distribution accepted by the operation detection unit 153, The basis weight of the second mesh W2 accumulated on the accumulation surface 72a of the second mesh forming portion 70 is controlled. According to this constitution, In the case of stacking materials containing fibers to manufacture the sheet S, The basis weight of the second web W2 can be controlled by setting the basis weight of the sheet S, And the sheet S of the basis weight set is manufactured. With this, The desired basis weight distribution can be achieved in the sheet S (as required). E.g, By making the basis weight of the central portion larger than the end portions in a specific direction within the plane of the sheet S, Can create strong waist in a specific direction, In addition, the sheet S with high transportability when transported by a printer or the like. The sheet manufacturing apparatus 100 is configured to have a drum portion 61 in which a plurality of openings 61a are formed, And the material passing through the opening 61a of the rotating drum portion 61 is accumulated on the accumulation surface 72a. The operation detection unit 153 uses, for example, the target distribution selection screen 160a, The basis weight distribution of the sheet S is accepted as the basis weight distribution of the specific direction (width direction WD) crossing the transport direction F of the second web W2. With this, When setting the basis weight distribution in a specific direction crossing the transport direction of the second web W2, The basis weight distribution of the second mesh W2 can be controlled according to this setting, The sheet S with a set basis weight distribution is manufactured. also, The sheet manufacturing apparatus 100 includes a basis weight sensor 309 that detects the thickness or basis weight of the second web W2 or the sheet S.

The control unit 150 is based on the detection result of the basis weight sensor 309, The basis weight distribution of the second web W2 in a specific direction crossing the transport direction F is controlled. In this case, The basis weight distribution of the sheet S can be controlled more appropriately. also, With the above sheet manufacturing apparatus 100, And the sheet S manufactured by the sheet manufacturing method of the sheet manufacturing apparatus 100 differs in the basis weight distribution in a specific direction that intersects the transport direction when transported by the transport roller pair nip. The sheet S has a larger basis weight in the center than the end in a specific direction. With this, The sheet S is compared with a sheet having the same basis weight as the entire sheet, The waist in the conveying direction can be strengthened by the roller pair, Sheet S with excellent transportability. also, The sheet S can also be manufactured in such a way that the thickness of the end portion in a specific direction is equal to the thickness of the central portion. In this case, It can realize the strength of the waist in the transport direction and excellent transportability by the basis weight distribution. And there is no sheet S with uneven thickness. [Second Embodiment] FIG. 13 is an enlarged view of a main part of a sheet manufacturing apparatus 101 to which a second embodiment of the present invention is applied, In particular, an enlarged front view of the display tube 54 and the airflow restricting portion 411. The sheet manufacturing apparatus 101 is constructed in the same manner as the sheet manufacturing apparatus 100 (FIG. 1) except for the airflow restricting portion 411 described below. Therefore, the same symbols are added to the common configuration and the description is omitted. The airflow restricting portion 411 shown in FIG. 13 is disposed above (upstream side) the branch portion 54b of the tube 54. The airflow restricting portion 411 has: The plate-shaped airflow restricting rotating plate 412, It is arranged from the side wall side of the main pipe 54a toward the axis center; And the rotating part 413, This causes the airflow restricting rotating plate 412 to rotate in the direction indicated by the arrow RD in the figure. In the example of Figure 13, The pair of airflow restricting rotating plates 412 are arranged one by one on the right direction R side and the left direction L side of the main pipe 54a. Each of the airflow restricting rotating plates 412 is independently controlled by the control device 110 by the rotating portion 413 to rotate. The position of the pair of airflow restricting rotating plates 412 is based on the branching position 54e of the branching and transporting airflow M1 of the branch 54b. Equivalent to the position of the branch pipe 54c side, And the location of the branch pipe 54d side. The airflow restricting portion 411 is provided instead of the airflow restricting portion 401 (FIG. 5) described in the first embodiment. which is, The sheet manufacturing apparatus 101 is configured to replace the airflow restricting portion 401 of the sheet manufacturing apparatus 100 with the airflow restricting portion 411. The airflow restricting portion 411 includes: A pair of airflow restricting rotating plates 412, And the rotating part 413 which moves a pair of air flow restricting rotating plates 412. The position of the airflow restricting portion 411 is preferably near the branch portion 54b, More preferably, it is provided in the main pipe 54a which is the state before branching with the branch part 54b. also, The best is on the supervisor 54a, The airflow restricting portion 411 is close to the branch portion 54b. The airflow restricting rotating plate 412 is rotated by the rotating portion 413, And at the position of the cross section opening of the main pipe 54a, Displacement with the position along the axial direction of the main pipe 54a. The area where the airflow restricting rotating plate 412 protrudes in the cross-sectional direction of the main pipe 54a is determined by the amount of rotation of the rotating portion 413. therefore, By the action of the rotating part 413, Inside Supervisor 54a, The cross-sectional area through which the conveying air flow M1 can vary. The rotating portion 413 corresponds to the basis weight adjusting portion 341, Moreover, the control device 110 can control the turning on and off of the operation of the rotating portion 413 and the rotating amount of the rotating portion 413. The control device 110 may be configured to independently control a pair of rotating parts 413, It may also be a controller that interlocks the pair of rotating parts 413. also, As shown in Figure 13, It is preferable to rotate the airflow restricting rotating plate 412 on the downstream side of the rotating portion 413. With this, The retention of the material of the airflow restricting portion 411 can be suppressed. When the airflow restricting rotating plate 412 rotates, On the right side R side or left side L side of the section of the main pipe 54a, The flow of the conveying airflow M1 is obstructed by the airflow restricting rotating plate 412. which is, The airflow restricting rotating plate 412 can affect the conveying airflow M1 flowing in the main pipe 54a. E.g, When the airflow restricting rotating plate 412 located on the right side R side protrudes toward the center of the main pipe 54a, On the right side R side from the center of the main pipe 54a, that is, the shunt position 54e, The flow path of the conveying air flow M1 becomes narrow. therefore, Inside Supervisor 54a, Ventilation resistance is generated on the R side in the right direction. In this state, The conveying airflow M1 collides with the airflow restricting rotating plate 412, And flow in a manner to restrict the rotating plate 412 around the air flow, Therefore, the material contained in the conveyance airflow M1 flows to the left side L side. Inside Supervisor 54a, By transferring the material to the left side L side, In branch 54b, Compared with the transport airflow M2, More material flows in the transport air flow M3. therefore, In the drum section 61, R side to the right, More material flows in from the left side L side. Compared to this, When the airflow restricting rotating plate 412 located on the left side L side protrudes toward the center of the main pipe 54a, On the left side L side from the center of the main pipe 54a, that is, the shunt position 54e, The flow path of the conveying air flow M1 becomes narrow. therefore, Inside Supervisor 54a, Ventilation resistance is generated on the left side L side. In this state, The conveying airflow M1 collides with the airflow restricting rotating plate 412, And flow in a manner to restrict the rotating plate 412 around the air flow, Therefore, the material included in the conveyance airflow M1 flows to the right in the right direction R side. Inside Supervisor 54a, By transferring the material to the right side R side, In branch 54b, Compared with the transport airflow M3, More material flows in the transport air stream M2. therefore, In the drum section 61, To the left of the left side, More material flows in from the right to the R side. also, The airflow restricting rotating plate 412 has an influence on the flow velocity of the conveying airflow M1, But the impact on the air volume is relatively slight, Therefore, the conveying airflow M2 flowing into the drum 61, The sum of the air volume of M3 is almost unchanged. however, The wind power of the hybrid blower 56 which generates the conveying airflow M1 is weak, In the case where the cross-sectional area of the main pipe 54a has a large proportion of the area reduced by the air flow restricting rotating plate 412, May reduce the air volume. According to the sheet manufacturing apparatus 101 of the second embodiment, By controlling the airflow restricting portion 411 with the basis weight adjustment control portion 157, the left-right balance of the material flowing from the tube 54 to the drum portion 61 can be changed. This effect is the same as the effect of controlling the airflow restricting portion 401 by the basis weight adjustment control portion 157 in the first embodiment. therefore, The sheet manufacturing apparatus 101 of the second embodiment has the same effect as the sheet manufacturing apparatus 100. also, Compared with the airflow restricting plate 402 provided in the airflow restricting portion 401 (FIG. 5), The airflow restricting rotating plate 412 constituting the airflow restricting portion 411 can be realized in a smaller size. therefore, Outside the supervisor 54a, When the space margin is small, The airflow restricting portion 411 has a more advantageous configuration. another, In the second embodiment described above, It is not limited to the configuration in which the tube 54 is a tube with a circular cross section, The tube 54 may be a tube with a rectangular cross section. which is, At a position where at least the airflow restricting portion 411 is provided, The main pipe 54a is constituted by a tube whose cross section is rectangular (square). In this case, By setting the airflow restricting rotating plate 412 as a rectangular plate, It can more effectively affect the flow of the conveying airflow M1 to a pair of suction restricting portions 512, The material distribution of the drum portion 61 can be adjusted more effectively. [Third Embodiment] FIG. 14 is a perspective view of a main part of a sheet manufacturing apparatus 102 according to a third embodiment, In particular, the configuration of the accumulation section 60 and the second mesh forming section 70 is shown. Since the sheet manufacturing apparatus 102 is in addition to the accumulation section 60a described below, Both are configured in the same manner as the sheet manufacturing apparatus 100 (FIG. 1), Therefore, the same symbols are added to the common configuration and the description is omitted. The sheet manufacturing apparatus 102 replaces the stacking section 60 (FIG. 3) of the sheet manufacturing apparatus 100 with the stacking section 60a, And set to the trachea 522a, 522b, Air supply device 523a, Composition of 523b. The accumulation part 60a is provided with the right side wall 64b instead of the right side wall 64 (FIG. 3), The left side wall 65b is provided instead of the left side wall 65 (FIG. 3). On the right side wall 64b, The air supply pipe 57a is connected like the right side wall 64, And the conveyance airflow M2 containing the material is supplied to the inside of the drum part 61 from the air supply pipe 57a. The right side wall 64b has a material supply port 64a that opens at a position corresponding to the inner side of the drum portion 61 and into which the transport airflow M2 flows. On the left side wall 65b, The air supply pipe 57b is connected like the left side wall 65, And the conveyance airflow M3 is supplied to the inside of the drum part 61 from the air supply pipe 57b. The left side wall 65b has a material supply port 65a that opens at a position corresponding to the inner side of the drum portion 61 and into which the conveying airflow M3 flows. also, An air supply port 521a for supplying air containing no material is formed in the right side wall 64b. The air supply port 521a is an opening for supplying the air supplied by the air supply pipe 522a connected to the right side wall 64b to the inside of the drum portion 61. The air supply port 521a extends in the direction of the rotation axis Q (FIG. 4) of the rotary cylinder 61 and penetrates the right side wall 64b, And it opens at a position overlapping with the inside of the rotating drum 61. The air supply port 521a is opened at a position different from the material supply port 64a in the radial direction of the drum portion 61. Similarly, An air supply port 521b for supplying air containing no material is formed on the left side wall 65b. The air supply port 521b is an opening for supplying the air supplied by the air supply pipe 522b connected to the left side wall 65b to the inside of the drum 61. The air supply port 521b penetrates the left side wall 65b in the direction of the rotation axis Q of the rotary cylinder 61, And it opens at a position overlapping with the inside of the rotating drum 61. The air supply port 521a is opened at a position different from the material supply port 65a in the radial direction of the drum portion 61. The air supply pipe 522a is connected to the air supply device 523a operated by the control of the control device 110. The air supply pipe 522b is connected to the air supply device 523b operated by the control of the control device 110. Air supply device 523a, 523b has a blower (not shown), etc., And to send air to the air supply pipe 522a, 522b device. Air supply device 523a, 523b can be, for example, the humidified air humidified by the humidifying section 208 (FIG. 1) and the like to the air supply pipe 522a 522b. or, The air (outside air) inside the sheet manufacturing apparatus 102 such as the periphery of the accumulation part 60a may be sent to the air supply pipe 522a, 522b. For any of these situations, The gas supply device 523a, The air containing no material supplied to the drum portion 61 by 523b is called outside air. Air supply device 523a, 523b from the material supply port 64a, 65a The amount of air flowing into the drum 61, The air volume corresponding to the difference in the air volume sucked by the suction mechanism 76 supplies the outside air. By giving trachea 522a, The external gas supplied by 522b corresponds to the external gas O1 O2 (Figure 3). Air supply device 523a, 523b corresponds to the intake adjustment part 342 (FIG. 9). The control unit 150 can adjust the air supply device 523a by the basis weight adjustment control unit 157, Each of 523b sends air to the air supply tube 522a, The air volume of the outside air of 522b. Using the air supply device 523a of the basis weight adjustment control unit 157, The control of 523b and the inhalation restricting portion 511 shown in FIGS. 3 and 4 The control of 512 is the same. The basis weight adjustment control unit 157 can control the air supply amount of the air supply device 523a, And the air supply volume of the air supply device 523b, Instead, the outside air flowing into the drum portion 61 from the air supply port 521a on the right side R side, It balances with the outside air flowing in from the air supply port 521b on the left side L side. in this way, The basis weight adjustment control unit 157 can adjust the intake port 501 in the first embodiment, The control of the opening area of 502 is the same, Control air supply device 523a, 523b and get the same effect. in this way, According to the sheet manufacturing apparatus 102 of the third embodiment, By controlling the air supply device 523a, 523b controls the material distribution inside the drum 61, The basis weight distribution of the sheet S in a specific direction (for example, the width direction WD) crossing the transport direction F is adjusted. another, Air supply device 523a, 523b can also be constructed as a gas supply device. In this case, Preferably with changes, Adjust the air supply volume (air volume) from the air supply device to the air supply pipe 522a, And a mechanism for supplying air volume (air volume) from the air supply device to the air supply pipe 522b. E.g, It is assumed that a branching portion for branching the air flow supplied by the air supply device to the air supply pipe 522a and the air supply pipe 522b is provided. The following components can also be used: A damper (not shown) is arranged on this branch to adjust the ratio of the air flow to the air supply pipe 522a and the air supply pipe 522b, And the position or driving state of the damper can be controlled by the control device 110. also, As shown in Figure 14, The sheet manufacturing apparatus 102 is shown to be provided with an air flow restricting portion 401 on the main pipe 54a. However, instead of the airflow restricting portion 401 included in the sheet manufacturing apparatus 102, an airflow restricting portion 411 (FIG. 12) may be provided. [Fourth Embodiment] FIGS. 15 to 19 are explanatory diagrams of a sheet manufacturing apparatus 103 according to a fourth embodiment. 15 is an exploded perspective view of the main part of the sheet manufacturing apparatus 103, Furthermore, an air intake position changing section 530 (position changing section) for changing the position of the air intake port for supplying air not containing material from the outside of the housing section to the inside of the rotating drum section is displayed. FIG. 16 is a diagram showing the first suction position of the suction port of the position changing section. Fig. 17 is a diagram showing the second suction position of the suction port, Fig. 18 is a diagram showing the third suction position of the suction port, Fig. 19 is a diagram showing the fourth suction position of the suction port. The sheet manufacturing apparatus 103 corresponds to the sheet manufacturing apparatus 100 of the first embodiment where the intake port 501 can be changed, The composition of the 502 position. The same symbols are attached to the configuration common to the sheet manufacturing apparatus 100, and the description is omitted. The intake position changing unit 530 of FIG. 15 includes: Opening position change plate 532, The driving portion 531 that rotates the opening position changing plate 532, And a wall plate 533 which is arranged to overlap the opening position changing plate 532. The opening position changing plate 532 and the wall plate 533 are circular plates, And it can be used as the right side wall 64 (Figure 3) And the left side wall 65 (Figure 3). The opening position changing plate 532 has a central opening 532a formed in the center, A peripheral opening 532b is formed at a position deviated from the center of the opening position changing plate 532. The outer peripheral opening 532b when the intake position changing portion 530 is arranged as the right side wall 64 or the left side wall 65, It is desirable to open at a position that overlaps with the cross-section of the drum portion 61. In this case, The central opening 532a functions as a material supply port 64a or a material supply port 65a, The outer peripheral opening 532b functions as an intake port 501 or an intake port 502. A central opening 533a is formed in the center of the wall plate 533. The location of the central opening 533a, The shape and size are set so as to overlap with the central opening 532a in a state where the opening position changing plate 532 and the wall plate 533 overlap. On siding 533, A peripheral opening 534a is formed at a position away from the central opening 533a, 534b, 534c, 534d. Peripheral opening 534a, 534b, 534c, 534d are openings of a size that can overlap the opening position changing plate 532, And, for example, they are evenly arranged in the circumferential direction of the wall plate 533. The intake position changing section 530 is configured to overlap the opening position changing plate 532 and the wall plate 533 so that the central opening 532a and the central opening 533a coincide. therefore, Central opening 532a, 533a forms a through hole, And as a material supply port 64a, 65a makes the transport airflow M2, M3 passed. The driving unit 531 can rotate the opening position changing plate 532, The angle of the opening position changing plate 532 relative to the wall plate 533 is changed. The wall plate 533 may be configured not to be rotated by the driving part 531, However, the relative angle between the wall plate 533 and the opening position changing plate 532 may be changed by the driving unit 531. When the opening position changing plate 532 rotates relative to the wall plate 533, According to the rotation position, The peripheral opening 532b and the peripheral opening 534a, 534b, 534c, Any one of 534d overlaps. also, There are also peripheral openings 532b and peripheral openings 534a, 534b, 534c, The state where none of 534d overlaps. When the outer peripheral opening 532b and the outer peripheral opening 534a overlap, Peripheral opening 532b, And the outer peripheral opening 534a forms a through hole, In addition, it functions as an intake port 501 or an intake port 502 to circulate outside air. About the peripheral opening 534b, 534c, The same is true for 534d. therefore, The opening position changing plate 532 can be rotated by 531, Change the rotation position of the opening position changing plate 532 relative to the wall plate 533, And from the peripheral opening 534a, 534b, 534c, 534d selects the opening where the outside air flows into the drum portion 61. The right side wall 64 side outer peripheral opening 534a, 534b, 534c, 534d corresponds to the first suction port, The outer peripheral opening 534a on the left side wall 65 side, 534b, 534c, All 534d correspond to the second suction port. also, The central opening 532a and the central opening 533a correspond to the material supply port. which is, When any one of the outer peripheral openings on the right side wall 64 side opening corresponds to the first suction port, Any outer peripheral opening opened on the left side wall 65 side corresponds to the second intake port. The right side wall 64 side and the left side wall 65 side may be opposite. The first intake position shown in FIG. 16 shows a state where the outer peripheral opening 532b and the outer peripheral opening 534a overlap. Since the outer peripheral opening 534a is located above the central opening 533a, So at the 1st inhalation position, In the drum section 61, The external air is supplied from the material supply port 64a, 65a flows in above. The second intake position shown in FIG. 17 shows a state where the outer peripheral opening 532b and the outer peripheral opening 534b overlap. The peripheral opening 534b is located at the same height as the central opening 533a, And it is located on the downstream side in the transport direction F. In the second inhalation position, In the drum section 61, At the material supply port 64a, 65a at the same height, Outside air flows in from the downstream side. The third intake position shown in FIG. 18 shows a state where the outer peripheral opening 532b and the outer peripheral opening 534c overlap. The peripheral opening 534c is located below the central opening 533a. In the 3rd inhalation position, In the drum section 61, External gas from the material supply port 64a, Inflow below 65a. The fourth intake position shown in FIG. 19 shows a state where the outer peripheral opening 532b and the outer peripheral opening 534d overlap. The peripheral opening 534d is located at the same height as the central opening 533a, And it is located on the upstream side in the transport direction F. In the 4th inhalation position, In the drum section 61, At the material supply port 64a, 65a at the same height, Outside air flows in from the upstream side. in this way, The control device 110 operates the driving unit 531, And the opening position changing plate 532 is rotated, Thereby, the position where the outside air flows into the drum portion 61 can be changed. In this composition, The intake position change unit 530 corresponds to the intake adjustment unit 342. The sheet manufacturing apparatus 103 of the fourth embodiment includes an intake position changing unit 530, This serves as a position changing section that changes the position for supplying the air not containing the material from the outside of the housing section 63 to the suction port of the drum section 61. With this, The distribution of the airflow flowing out of the rotary drum 61 can be changed by changing the distribution of the airflow flowing into the rotary drum 61. therefore, The distribution of the material accumulated through the opening 61a of the drum portion 61 can be changed, The basis weight distribution of the manufactured sheet S is controlled. also, On the 1st 2nd, In the 3rd and 4th suction position, Shows the outer peripheral opening 532b and the outer peripheral opening 534a, 534b, 534c, Any one of 534d completely overlaps, This maximizes the opening area. The control of the sheet manufacturing apparatus 103 is not limited to this, For example, the outer peripheral opening 532b and the outer peripheral opening 534a may be 534b, 534c, The state that any one of 534d only partially overlaps. In this case, Ventilation resistance can be generated relative to the inflow of external air. E.g, The balance of the intake amount of the outside air in the right direction R side and the left direction L side of the drum portion 61 can be changed. FIG. 20 is a graph showing the basis weight distribution of the sheet S manufactured by the sheet manufacturing apparatus 103, An example of the basis weight distribution of the sheet S when the driving condition of the sheet manufacturing apparatus 103 is changed is displayed. In more detail, FIG. 20 summarizes the results of controlling the basis weight distribution of the sheet S in the sheet manufacturing apparatus 103 in a graph. Figure 20 shows examples 1-7 of the present invention, And the results of comparative examples used for comparison. In Examples 1 to 7 and Comparative Examples, As the driving condition of the sheet manufacturing apparatus 103, Set feed control, Relative to the air flow rate of the suction air flow rate, Inspiratory ratio, Inhalation position. Material feed control refers to the control of restricting the flow of the conveying airflow M1 by the airflow restricting portion 401, And can switch the control to restrict the air flow on the right side R, Control of the air flow on the L side in the left direction, And control without restrictions. The ratio of the conveying airflow volume to the suction airflow volume is to control the ratio of the conveying airflow M1 supplied to the drum 61 and the suction airflow M4 Set the amount of the operating state of the normal sheet manufacturing apparatus 100 to 103 to "large", The state where the ratio is reduced by the control of the hybrid blower 56 is set to "small". The left and right inhalation ratio refers to the balance of the inflow amount (inhalation amount) of outside air flowing into the drum 61, And it can be switched to the control of the inspiratory volume on the left side L = the inspiratory volume on the right side R, Make the left side L side intake more than the right side R side control, And the control to make the intake amount on the left side L side less than the right side R side. The suction positions 1 to 4 are the suction positions shown in FIGS. 16 to 19, respectively. 20 shows the basis weight distribution of the sheet S in the width direction WD as a result corresponding to each driving condition. The basis weight distribution of the sheet S is such that the vertical axis is the basis weight, Set the horizontal direction to the width direction WD plot (O) display, The left and right directions of the width direction WD are indicated by the symbol R, L shown. In Example 1, Shows no feed control, Reduce the proportion of the conveying airflow relative to the suction airflow, Set the left and right inhalation ratio to the left direction L = right direction R, An example of setting the second suction position. In the case where the sheet manufacturing apparatus 103 operates in Embodiment 1, As shown in Figure 20, The sheet material S in which the basis weight of the central portion of the width direction WD is larger than the basis weight of the end portions is obtained. In Example 2, Shows no feed control, Set the proportion of the conveying airflow relative to the suction airflow to normal (large), Set the left and right inhalation ratio to the left direction L = right direction R, An example of setting the third suction position. In the case where the sheet manufacturing apparatus 103 operates in Embodiment 2, As shown in Figure 20, The sheet material S in which the basis weight of the central portion of the width direction WD is larger than the basis weight of the end portions is obtained. In Example 3, Shows no feed control, Set the proportion of the conveying airflow relative to the suction airflow to normal (large), Set the left and right inhalation ratio to the left direction L = right direction R, An example of setting the first suction position. In the case where the sheet manufacturing apparatus 103 operates in Embodiment 3, As shown in Figure 20, A sheet S in which the basis weight of the central portion of the width direction WD is smaller than the basis weight of the end portions is obtained. In comparison with Example 2, A basis weight distribution that differs depending on the inhalation position can be obtained. In Example 4, The airflow restricting plate 402 protrudes beyond the right direction R side of the cross section of the main pipe 54a by the airflow restricting portion 401. Regarding other driving conditions, Set the proportion of the conveying airflow relative to the suction airflow to normal (large), Set the left and right inhalation ratio to the left direction L = right direction R, And set the second suction position. In Example 5, The airflow restricting plate 402 protrudes to the left side L side of the cross section of the main pipe 54a by the airflow restricting portion 401. Regarding other driving conditions, Set the proportion of the conveying airflow relative to the suction airflow to normal (large), Set the left and right inhalation ratio to the left direction L = right direction R, And set the second suction position. In Examples 4 and 5, In addition to the restricted state of the airflow restricting portion 401, Common driving conditions, Therefore, the basis weight distribution of the sheet S reflects the difference in the control of the airflow restricting portion 401. In Example 4, the distribution of the increase in the basis weight of the end of the left side L side compared to the right side of the R side is obtained, In Example 5, the distribution in which the end portion in the right direction R side is larger in weight than the end portion in the left direction L side is obtained. In Example 6, No feed control, The ratio of the conveying airflow volume to the suction airflow volume is set to normal (large). Control the ratio of left and right inhalation in such a way that the inhalation amount in the left direction L is greater than the right direction R, And set the second suction position. In Example 7, No feed control, The ratio of the conveying airflow volume to the suction airflow volume is set to normal (large). Control the ratio of left and right inhalation in such a way that the inhalation amount in the left direction L is smaller than the right direction R, And set the second suction position. In Examples 6 and 7, In addition to the balance of the left and right inspiratory volume, Common driving conditions, Therefore, the basis weight distribution of the sheet S reflects the difference between the left-right balance of the inspiratory volume. In Example 6, a distribution in which the basis weight of the end on the right side R side is increased compared to the end on the left side L side is obtained, Contrary to Example 7, A distribution in which the basis weight of the end on the left side L side is larger than that on the right side R side is obtained. also, In the comparative example, No feed control, Set the proportion of the conveying airflow relative to the suction airflow to normal (large), Does not control the ratio of left and right inhalation, And set the second suction position. In the comparative example, the basis weight distribution of the sheet S is substantially fixed in the width direction WD. also, Although not shown, However, the fourth suction position can obtain the same result as the case where the second suction position is adopted. According to the embodiments of FIG. 20, Based on comparison with comparative examples, It can be clearly understood that the airflow restriction part 401 can be used to control the airflow, Relative to the air flow rate of the suction air flow rate, The position of the suction port is changed by the suction position changing unit 530, Either of the ratio of left and right inhalation of external air, The basis weight distribution of the width direction WD of the sheet S is changed. The material feed control can be similarly controlled by using the configuration of the airflow restricting portion 411 described in the second embodiment. The left-right intake ratio can be changed in the configurations of the first to third embodiments. therefore, According to the sheet manufacturing apparatus 100 described in the first to fourth embodiments, 101, 102, 103, The basis weight distribution in the width direction WD of the sheet S can be controlled by the control unit 150 controlling the driving conditions of the device. therefore, The sheet S having the desired basis weight distribution can be manufactured. another, The above-mentioned embodiments are only specific aspects of implementing the invention described in the patent application scope, Not to limit the inventor, It is not limited that all the components described in the above embodiments are essential components of the present invention. also, The present invention is not limited to the constitution of the above-mentioned embodiment, It can be implemented in various forms without departing from the scope of the subject.
