Description

  The present invention relates to a sheet conveying apparatus and a conveying method, and more particularly to an apparatus and a method for transferring a sheet from a transfer roll to a conveyor belt.

  A technique is known in which each leaf sheet transported while being held on the peripheral surface of the transfer roll is transferred onto a conveyor belt disposed facing the transfer roll. For example, the present applicant has previously proposed a method for producing a surface sheet of an absorbent article (see Patent Document 1). In this method, a long strip-shaped non-woven fabric is cut into a sheet 12 for each leaf using a cut slip device 24 equipped with a cutter roll 25 and a transfer roll 26. The cut sheet 12 is transferred from the transfer roll 26 to another roll 22 and then transferred onto another long belt-shaped nonwoven fabric 11. According to this method, each sheet 12 is transferred onto the long strip-shaped nonwoven fabric 11 at a predetermined interval.

  Although it is not a surface sheet of an absorbent article, Patent Document 2 describes a technique for manufacturing a laminated base material sticking film by disposing a sheet of each leaf intermittently on a long belt-like sheet.

  According to the manufacturing method described in Patent Document 1, it is possible to transfer each sheet 12 on a long strip-shaped nonwoven fabric 11 at a predetermined interval. However, since the drive source of the long strip-shaped nonwoven fabric 11 and the drive source of the roll 22 for transferring the sheet 12 of each leaf to the nonwoven fabric 11 are different, the running speed of the nonwoven fabric 11 and the peripheral speed of the roll 22 are different. As a result, there may be a shift in the transfer position of the sheet 12 of each leaf.

  Since the manufacturing method described in Patent Document 2 requires a large-scale apparatus using a CCD camera in order to correct the position of the sheet, the manufacturing apparatus becomes complicated and the manufacturing cost increases.

  Accordingly, an object of the present invention is to provide a sheet conveying apparatus and a conveying method that can eliminate the drawbacks of the above-described conventional techniques.

FIG. 2 is a schematic diagram showing a composite sheet manufacturing apparatus having the basic structure of the sheet conveying apparatus shown in FIG. FIG. 3 is a schematic view showing a second embodiment of the sheet conveying apparatus of the present invention. FIG. 4 is a schematic view showing a third embodiment of the sheet conveying apparatus of the present invention.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 schematically shows a first embodiment of the sheet conveying apparatus of the present invention. The transport apparatus 10 illustrated in FIG. 1 includes a cutting unit 20 that includes a rotary die cutter 21 and a transfer roll 22. The conveying device 10 includes a sheet conveying unit 30. Hereinafter, each of these parts will be described.

  The rotary die cutter 21 provided in the cutting part 20 is configured to rotate in the direction of the arrow in FIG. The rotary die cutter 21 includes a roll body 21a and a plurality of cutting blades 21b arranged on the peripheral surface of the roll body 21a. The cutting blade 21 b is a straight blade extending in the axial direction of the roll body 21. When viewed from the axial direction of the roll main body 21a, the cutting blades 21b are arranged at equal intervals with a 90-degree separation from each other with respect to the radial direction of the roll main body 21a. Therefore, in this embodiment, four cutting blades 21b are used. However, the number of the cutting blades 21b is not limited to this, and may be 1 to 3, or 5 or more. When using the some cutting blade 21b, the space | interval of each cutting blade 21b may be equal intervals, or may not be so. The cutting blade 21b is not limited to a straight blade, and an oblique blade, a zigzag blade, or the like can also be used.

  In addition to the rotary die cutter 21, the cutting unit 20 includes a transfer roll 22. The transfer roll 22 is arranged so that its axis is parallel to the axis of the rotary die cutter 21. The transfer roll 22 is arranged in such a positional relationship that its peripheral surface comes into contact with the tip of the cutting blade 21b of the rotary die cutter 21 or is separated with a predetermined clearance.

  A large number of suction holes (not shown) are provided on the peripheral surface of the transfer roll 22. Each suction hole communicates with a conduit (not shown) formed in the transfer roll 22. This conduit is connected to a suction source such as a vacuum pump (not shown). When the suction source is activated to perform suction, the sheet can be adsorbed on the peripheral surface of the transfer roll 22, and the transfer roll 22 can be rotated under the adsorbed state.

  The transport apparatus 10 according to the present embodiment includes a sheet transport unit 30 in addition to the cutting unit 20. The sheet conveying unit 30 includes a conveyor belt that travels in one direction. Specifically, an endless conveyor belt 31 that circulates in the direction of the arrow in FIG. 1 is provided. The conveyor belt 31 is disposed in such a positional relationship that the surface thereof is in contact with the peripheral surface of the transfer roll 22 of the cutting unit 20. Further, the conveyor belt 31 is disposed such that its traveling direction is the same as the rotation direction of the transfer roll 22 of the cutting unit 20.

  A nip roll 32 is installed at a position facing the transfer roll 22 with the conveyor belt 31 in between. The nip roll 32 is installed such that its axis is parallel to the axis of the transfer roll 22. Further, the nip roll 32 is arranged in a positional relationship such that the peripheral surface thereof abuts on the back surface of the conveyor belt 31.

  In the sheet conveying unit 30, a suction box 33 as a suction mechanism is installed inside a circulating conveyor belt 31. The suction box 33 is installed on the downstream side of the installation position of the nip roll 32 with respect to the traveling direction of the conveyor belt 31. Further, the suction box 33 is installed in such a positional relationship that its suction surface faces the back surface of the conveyor belt 31. The suction box 33 is connected to a suction source (not shown). The suction box 33 is used for the purpose of sucking and fixing a conveyance object conveyed by the conveyor belt 31 to the surface of the conveyor belt 31. For this purpose, the conveyor belt 31 is preferably made of a breathable material. As such a material, for example, a metal or synthetic resin mesh belt can be used.

  In the conveying device 10 of the present embodiment, one or two or more leaf sheets disposed on the peripheral surface of the transfer roll 22 in the cutting unit 20 are transferred from the transfer roll 22 to the conveyor belt 31, that is, In FIG. 1, one of the features is that the conveyor belt 31 is driven by driving the transfer roll 22 at the position indicated by the symbol A. Specifically, the conveyor belt 31 is sandwiched between the transfer roll 22 and the nip roll 32, and the transfer roll 22 and the nip roll 32 are driven by the same drive source (not shown). For example, a rotational force from a rotating shaft attached to one electric motor is branched by a rotating belt or the like and transmitted to the transfer roll 22 and the nip roll 32. By adopting such a configuration, it is possible to mechanically synchronize the peripheral speed of the transfer roll 22 and the traveling speed of the conveyor belt 31. As a result, when the leaf sheets arranged on the peripheral surface of the transfer roll 22 are continuously transferred to the conveyor belt 31, the positional deviation between the leaf sheets before and after the running direction of the conveyor belt 31 is achieved. The leaf sheets can be transferred without causing them to occur.

  Specifically, the operation of the transport apparatus 10 of the present embodiment is as follows. As shown in FIG. 1, in the cutting unit 20, for example, a long belt-like sheet 40 is supplied between a rotary die cutter 21 and a transfer roll 22. The sheet 40 supplied between the rotary die cutter 21 and the transfer roll 22 is cut across the width direction by the pressure between the cutting blade 21 b and the peripheral surface of the transfer roll 22, and becomes a leaf sheet 41. As described above, a suction hole (not shown) is provided in the peripheral surface of the transfer roll 22 and suction toward the inside of the roll is performed through the suction hole. Each leaf sheet 41 formed by cutting 40 is conveyed without being detached from the transfer roll 22 while being held on the peripheral surface of the roll 22. Further, in this embodiment, each leaf sheet 41 is conveyed in a state where there is substantially no gap between the two leaf sheets 41 that are adjacent to each other in the rotation direction of the transfer roll 22. The

  Each leaf sheet 41 conveyed by the transfer roll 22 is continuously transferred to the conveyor belt 31 at the position indicated by the symbol A in FIG. In this case, as described above, since the peripheral speed of the transfer roll 22 and the traveling speed of the conveyor belt 31 are the same, the leaf sheets 41 transferred onto the conveyor belt 31 are transferred to the conveyor belt 31. There is no gap between the leaf sheets 41 before and after the running direction of 31. As described above, when the conveyance device 10 of the present embodiment is used, the leaf sheet 41 is transferred to the transfer roll 22 while the interval between the leaf sheets 41 on the peripheral surface of the transfer roll 22 is reliably maintained. To the conveyor belt 31. In order to perform transfer more smoothly, when transferring the leaf sheets 41 from the transfer roll 22 to the conveyor belt 31, air is sprayed from the inside of the transfer roll 22 to the outside, and from the peripheral surface of the transfer roll 22. It is preferable to promote the peeling of each leaf sheet 41. For this purpose, the aforementioned suction holes (not shown) of the ambi roll 22 can be used. Specifically, when the leaf sheets 41 are transferred from the transfer roll 22 to the conveyor belt 31, the suction holes are connected to a high-pressure air source (not shown), and air is directed from the high-pressure air source toward the suction holes. Should be sent. By combining this operation with the suction holding of the leaf sheet 41 on the conveyor belt 31 by the suction box 33 described above, the receipt of the leaf sheet 41 peeled off from the peripheral surface of the transfer roll 22 is further ensured. be able to.

  Each leaf sheet 41 transferred onto the conveyor belt 31 is conveyed while being held on the conveyor belt 31 by suction by the suction box 33 and supplied to the next process. In the next step, various types of processing are performed on each sheet 41. Examples of such processing include a step of adding a chemical solution to each leaf sheet 41, a step of sealing the leaf sheet 41, a step of packaging the leaf sheet 41, and the like.

The conveyance device 10 of the present embodiment having the above configuration is suitably used for manufacturing absorbent articles such as sanitary napkins and disposable diapers, heating element sheets, cleaning sheets, cosmetic sheets, and the like.

  FIG. 2 shows a modification of the present embodiment. This figure shows a composite sheet manufacturing apparatus 100 having the basic structure of the sheet conveying apparatus 10 shown in FIG. The manufacturing apparatus 100 includes a cutting unit 20 and a sheet conveyance unit 30 as in the conveyance device illustrated in FIG. The configurations of the cutting unit 20 and the sheet conveying unit 30 are the same as those of the sheet conveying apparatus 10 shown in FIG. Further, the manufacturing apparatus 100 includes a pitch changing unit 50 between the cutting unit 20 and the sheet conveying unit 30.

  The pitch changing unit 50 includes a transfer roll 22. Similar to the anvil roll 51 of the cutting part 20, the transfer roll 22 is provided with a number of suction holes (not shown) on the peripheral surface thereof, and the sheet 41 can be sucked and held on the peripheral surface. ing.

  In the manufacturing apparatus 100 illustrated in FIG. 2, the cutting unit 20 includes a rotary die cutter 21 and an anvil roll 51, unlike the transport apparatus 10 illustrated in FIG. 1. The conveyor belt 31 is sandwiched between the transfer roll 22 and the nip roll 32. Further, the transfer roll 22 and the nip roll 32 are configured to be driven by the same drive source (not shown). By adopting such a configuration, it is possible to make the peripheral speed of the transfer roll 22 and the traveling speed of the conveyor belt 31 the same speed as in the transport apparatus 10 shown in FIG.

  As described above, in the manufacturing apparatus 100, the transfer roll 22 and the nip roll 32 are configured to be driven by the same drive source. However, the anvil roll 51 of the cutting unit 20 is the same as the transfer roll 22 and the nip roll 32. It may be configured to be driven by a drive source, or may be configured to be driven by another drive source.

  In the manufacturing apparatus 100, the peripheral speeds of the rotary die cutter 21 and the anvil roll 51 provided in the cutting unit 20 are set to the same speed. On the other hand, the peripheral speed of the transfer roll 22 provided in the pitch changing unit is set higher than the peripheral speed of the rotary die cutter 21 and the anvil roll 51. By setting the peripheral speed in this way, it is possible to change the pitch between the adjacent leaf sheets 41 before and after in the transport direction. The pitch referred to here is the distance between the central portions in the transport direction between adjacent leaf sheets 41 before and after in the transport direction. The specific operation is as follows.

  As shown in FIG. 2, a long belt-like sheet 40 is supplied between the rotary die cutter 21 and the anvil roll 51 of the cutting part 20, and the sheet 40 is cut across its width direction to form a leaf sheet 41. . Each leaf sheet 41 is conveyed while being sucked and held on the peripheral surface of the anvil roll 51. In this state, there is substantially no gap between adjacent leaf sheets 41 before and after in the transport direction.

  Each leaf sheet 41 conveyed by the anvil roll 51 is then transferred to the transfer roll 22. In order to perform the transfer smoothly, the suction provided on the peripheral surface of the anvil roll 51 at the transfer position of the leaf sheet 41 from the anvil roll 51 to the transfer roll 22 (the position indicated by B in FIG. 2). It is preferable that air is ejected outward from a hole (not shown) to promote separation of the leaf sheet 41 from the peripheral surface of the anvil roll 51. On the other hand, at the position B, the transfer roll 22 sucks air into the roll through a suction hole (not shown) provided on the peripheral surface thereof, and the leaf sheet 41 peeled off from the peripheral surface of the anvil roll 51. It is preferable to ensure receipt of.

  In transferring the leaf sheet 41 from the anvil roll 51 to the transfer roll 22, the peripheral speed V2 of the transfer roll 22 is larger than the peripheral speed V1 of the anvil roll 51 ( That is, a gap is generated between the leaf sheets 41 continuously transferred to the transfer roll 22 when V1 <V2. That is, the pitch between the leaf sheets 41 adjacent to each other before and after in the transport direction is widened, and the pitch is changed. In the transfer roll 22, each leaf sheet 41 is transported with a certain gap between the leaf sheets 41 adjacent to each other before and after in the transport direction.

  Each leaf sheet 41 conveyed to the peripheral surface of the transfer roll 22 is transferred to the conveyor belt 31 at a position indicated by a symbol A in FIG. In this case, since the transfer roll 22 and the nip roll 32 are configured to be driven by the same drive source (not shown), the pitch between the leaf sheets 41 before and after the transfer of the leaf sheets 41 is set. Is maintained.

  As shown in FIG. 2, in the manufacturing apparatus 100, a long belt-like base sheet 42 having air permeability is conveyed by the conveyor belt 31. Accordingly, the leaf sheets 41 transferred from the transfer roll 22 are superposed on the base sheet 42. The pitch P <b> 1 between the leaf sheets 41 transferred onto the base sheet 42 is the same as the pitch between the leaf sheets 41 sucked and held on the peripheral surface of the transfer roll 22.

  In this way, a composite sheet 43 is obtained in which a plurality of leaf sheets 41 are intermittently arranged on the base sheet 42 at a predetermined pitch P1. In this state, since the base sheet 42 and the leaf sheet 41 are not joined, the sheets 41 and 42 may be joined in the next downstream process. Alternatively, when each leaf sheet 41 is transferred onto the base sheet 42, both sheets 41 and 42 may be joined. In the latter case, for example, by applying an adhesive to the outer surface of each leaf sheet 41 being conveyed by the transfer roll 22, both sheets 41 and 42 can be joined at the time of transfer.

  The composite sheet thus obtained is suitably used as a constituent member (surface sheet or the like) of an absorbent article such as a sanitary napkin or disposable diaper, a constituent member (ventilation sheet) of a heating element sheet, or the like.

  Next, 2nd and 3rd embodiment of this invention is described, referring FIG.3 and FIG.4. In these embodiments, differences from the embodiment shown in FIG. 1 and FIG. 2 described above will be mainly described, and the description of the embodiment shown in FIG. 1 and FIG. The 3 and 4, the same members as those in FIGS. 1 and 2 are denoted by the same reference numerals.

  3 includes a cutting unit 20 including a rotary die cutter 21 and a transfer roll 22 in the same manner as the conveyance device illustrated in FIG. However, the sheet conveying unit 30 is not provided with a nip roll. Further, the structure of the transfer roll 22 is different from that of the transfer apparatus shown in FIG. Furthermore, the structure of the conveyor belt 31 in the transport unit 30 is also different. Specifically, it is as follows.

  The transfer roll 22 in the transport device 10 shown in FIG. 3 has a concavo-convex portion 22a in a part of its width direction over its circumferential direction. Specifically, the transfer roll 22 has uneven portions 22a made of gear teeth on the left and right sides in the width direction over the circumferential direction. On the other hand, the conveyor belt 31 extends in the running direction of the conveyor belt 31 (the direction indicated by the arrow D in FIG. 3) at a position facing the uneven portion 22a of the transfer roll 22, and the uneven portion 31a meshes with the uneven portion 22a. have. The uneven portion 31 a of the conveyor belt 31 is provided on the left and right sides of the conveyor belt 31 in the width direction. The uneven portion 31a has a shape of a rack (straight gear). The uneven portion 22a of the transfer roll 22 and the uneven portion 31a of the conveyor belt 31 are in mesh with each other.

  In the conveyance device 10 of the present embodiment, the transfer roll 22 is rotated under the state where the uneven portion 22a of the transfer roll 22 and the uneven portion 31a of the conveyor belt 31 are engaged with each other. This rotational force is transmitted to the conveyor belt 31 via the concave and convex portions 22a and 31a meshing with each other, and the conveyor belt 31 travels. Thus, also in this embodiment, the conveyor belt is driven by the drive of the transfer roll 22 at the position where each leaf sheet 41 is transferred from the transfer roll 22 to the conveyor belt 31 (the position indicated by symbol A in FIG. 3). 31 is driven. As a result, the peripheral speed of the transfer roll 22 and the running speed of the conveyor belt 31 are mechanically synchronized. Therefore, when the leaf sheets 41 arranged on the peripheral surface of the transfer roll 22 are continuously transferred to the conveyor belt 31, a positional shift is generated between the leaf sheets 41 before and after the running direction. Therefore, the sheet 41 can be transferred.

  In the conveying device 10 shown in FIG. 3, the uneven portions 22a provided on the transfer roll 22 are located on the left and right side portions in the width direction of the roll 22, but the positions where the uneven portions 22a are provided are as follows. Any position is possible as long as it does not hinder the conveyance of the long belt-like sheet 40 or the cutting of the sheet 40. Although not shown, a suction mechanism similar to the suction box 33 shown in FIG. 1 is installed in the conveyor belt 31 at the position shown in FIG.

  The transport apparatus 10 shown in FIG. 4 is different in the structure of the transfer roll 22 and the conveyor belt 31 from the transport apparatus shown in FIG. Specifically, the transfer roll 22 in the transport device 10 shown in FIG. 4 has a plurality of protrusions 22b in a part of its width direction over the circumferential direction. Specifically, the transfer roll 22 has protrusions 22b arranged at predetermined intervals on the left and right side portions in the width direction over the circumferential direction. On the other hand, the conveyor belt 31 extends in the running direction of the conveyor belt 31 (the direction indicated by the arrow D in FIG. 4) at a position facing the protruding portion 22b of the transfer roll 22, and is inserted into the protruding portion 22b. Hole portion 31b. Each hole 31b is provided on the left and right sides of the conveyor belt 31 in the width direction. The holes 31b are arranged in a line along the traveling direction of the conveyor belt 31. Each protrusion 22 b of the transfer roll 22 can be inserted into each hole 31 b of the conveyor belt 31.

  In the transport device 10 of the present embodiment, the transfer roll 22 is rotated while the protrusion 22b of the transfer roll 22 is inserted into the hole 31b of the conveyor belt 31. This rotational force is transmitted to the conveyor belt 31 so that the conveyor belt 31 travels. Thus, also in the present embodiment, the conveyor belt is driven by the transfer roll 22 at the position where each leaf sheet 41 is transferred from the transfer roll 22 to the conveyor belt 31 (the position indicated by the symbol A in FIG. 4). 31 is driven. As a result, since the peripheral speed of the transfer roll 22 and the traveling speed of the conveyor belt 31 are mechanically synchronized, the sheet 41 is moved without causing a positional shift between the sheets 41 before and after the traveling direction. It can be transferred to the conveyor belt 31.

  In the conveyance device 10 shown in FIG. 4, the protrusions 22b provided on the transfer roll 22 are located on the left and right sides in the width direction of the roll 22, but the positions where the protrusions 22b are provided are as follows. Any position is possible as long as it does not hinder the conveyance of the long belt-like sheet 40 or the cutting of the sheet 40. Although not shown, a suction mechanism similar to the suction box 33 shown in FIG. 1 is installed in the conveyor belt 31 at the position shown in FIG.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, the conveyance apparatus according to the embodiment shown in FIGS. 3 and 4 may be used as a basic structure and applied to a composite sheet manufacturing apparatus as shown in FIG.

  Moreover, you may combine the drive mechanism of the conveyor belt of embodiment shown in FIG. 1, and the drive mechanism of the conveyor belt of embodiment shown in FIG. 3 or FIG.

  In addition, in the manufacturing apparatus 100 shown in FIG. 2, the leaf sheet 41 is transferred onto the breathable base sheet 42. Instead, the leaf sheet 41 is transferred onto the non-breathable base sheet. May be. In this case, since the leaf sheet 41 cannot be sucked and fixed through the base sheet 42, instead of this suction and fixing, the surface of the leaf sheet 41 facing the base sheet 42 or the leaf sheet 41 in the base sheet 42 Each leaf sheet can be fixed on the base sheet by applying an adhesive to the opposite surface. Adhesion of the leaf sheets 41 to the base sheet 42 can be performed immediately after transfer or at the time of transfer.
