  2. Description of the Related Art Conventionally, in a textile machine such as a spinning machine, a configuration for performing processing for calculating a consumption length of a sliver in order to efficiently replenish a sliver as a raw material is known. Patent documents 1 to 3 disclose this kind of textile machine.

  Patent Document 1 discloses a production management device such as an open-end spinning machine. This production management device calculates the consumption length of the sliver and notifies the operator when the consumption length of the sliver reaches a preset amount. The production management device calculates the consumption length of the sliver by detecting the rotation of the drive shaft that drives the winding drum or the draw-off roller.

  However, in patent document 1, since it is the structure which detects rotation of the drive shaft which drives the winding drum or draw-off roller of the downstream of a fiber running direction rather than a spinning apparatus, the exact consumption length of a sliver cannot be detected. . For example, even if a fiber loss occurs in the spinning device, the sliver consumption length based on the fiber loss cannot be reflected in the overall sliver consumption length. Furthermore, even if a part of the yarn is removed in order to remove a yarn defect or the like from the yarn wound on the package, the consumption length of the sliver based on the removed yarn is reflected in the overall consumption length of the sliver. It is also difficult to do. Further, Patent Document 2 is a configuration for detecting a sliver terminal, and is not a configuration for specifically calculating the sliver consumption length. In Patent Document 3, since the case replacement time is calculated based on the set spinning speed, the case replacement time may not be accurately calculated.

  A main object of the present invention is to provide a configuration for accurately calculating the consumption length of a sliver in an air spinning machine that performs air spinning.

Means and effects for solving the problems

  According to a first aspect of the present invention, an air spinning machine having the following configuration is provided. That is, the pneumatic spinning machine includes a guide device, a supply device, an pneumatic spinning device, an electric motor, and a control unit. The guide device guides the sliver. The supply device includes a conveyance roller for feeding a sliver guided by the guide device, and supplies the sliver as a fiber bundle. The pneumatic spinning device generates a spun yarn by twisting the fiber bundle supplied by the supply device by an air flow. The electric motor drives the transport roller, and the amount of rotation is controlled according to an instruction signal. The control unit calculates a consumption length of the sliver based on the instruction signal.

  Thus, the consumption length of the sliver can be calculated without using a sensor that directly detects the rotation amount of the transport roller or the like. Therefore, it is possible to avoid complication of the configuration of the pneumatic spinning machine and an increase in cost due to the addition of the sensor. In addition, since the calculation is performed based on the rotation amount of the conveying roller that sends the sliver, the consumption length of the sliver can be accurately calculated as compared with the method of calculating the consumption length of the sliver using the spinning speed or the like.

  According to a second aspect of the present invention, an air spinning machine having the following configuration is provided. That is, the pneumatic spinning machine includes a guide device, a supply device, an air spinning device, and a control unit. The guide device guides the sliver. The supply device includes a conveyance roller for feeding a sliver guided by the guide device, and supplies the sliver as a fiber bundle. The pneumatic spinning device generates a spun yarn by twisting the fiber bundle supplied by the supply device by an air flow. The control unit calculates a consumption length of the sliver based on a rotation amount of the transport roller or a member that rotates in synchronization with the transport roller.

  Since the conveying roller of the supply device is arranged upstream of the pneumatic spinning device, the consumption length of the sliver can be accurately calculated without being affected by fiber loss or the like in the pneumatic spinning device.

  The pneumatic spinning machine preferably includes a plurality of spinning units each having at least the supply device and the pneumatic spinning device.

  In an air spinning machine including a plurality of spinning units, it is difficult for an operator to grasp the sliver consumption length of each spinning unit, and thus the effects of the present invention can be more effectively exhibited.

  The pneumatic spinning machine preferably has the following configuration. That is, the control unit performs a process of calculating the remaining length of the sliver based on the consumption length of the sliver. The control unit is capable of controlling the supply device to stop for each spinning unit based on the calculated remaining length of the sliver, and in the control, the upstream end of the sliver in the fiber traveling direction is The supply device is stopped so as to be arranged at a position upstream of the guide device.

  This eliminates the need to set the sliver in the guide device when, for example, refilling the sliver (replacing the sliver can), so that the sliver can be replenished in a short time, and the operating efficiency of the entire pneumatic spinning machine is reduced. Can be avoided.

  In the pneumatic spinning machine, the control unit, based on the initial length information of the sliver, and the fiber traveling speed, the remaining time until the sliver runs out in any of the plurality of spinning units, and It is preferable to calculate at least one of the total quantity of the sliver that needs to be replenished within a predetermined time.

  As a result, information for assisting sliver replenishment is calculated, so that, for example, sliver replenishment can be performed efficiently.

  The pneumatic spinning machine preferably has the following configuration. That is, the pneumatic spinning machine includes a first display unit that displays information related to the plurality of spinning units. The first display unit displays at least one of the remaining time and the quantity calculated by the control unit.

  As a result, the operator who replenishes the sliver can easily replenish the sliver or complete the replenishment before the sliver runs out by checking the display on the first display unit.

  The pneumatic spinning machine preferably has the following configuration. That is, the pneumatic spinning machine includes a notification unit that is individually arranged in the spinning unit and configured to be able to switch between a notification state and a non-notification state. In the spinning unit in which the informing unit is arranged, when the remaining length of the sliver of the spinning unit is equal to or less than a predetermined length, and in the spinning unit using the current sliver When the remaining spinning time becomes equal to or shorter than the predetermined time, the notification state is switched to at least one of them.

  Thereby, since the operator who replenishes a sliver can confirm the alerting | reporting content of an alerting | reporting part, the spinning unit which needs replenishment of a sliver can be identified early, Therefore Replenishment of a sliver can be performed efficiently.

  The pneumatic spinning machine preferably has the following configuration. That is, the pneumatic spinning machine includes a second display unit that is individually arranged in the spinning unit and can display at least numerals. The second display unit displays at least one of a remaining length of the sliver and a remaining time until the sliver runs out for the spinning unit in which the second display unit is arranged.

  As a result, the usage status of the sliver of each spinning unit is displayed in detail, so that the operator who replenishes the sliver can efficiently replenish the sliver by checking this display.

  The pneumatic spinning machine preferably includes a transmission unit that transmits to the outside at least one of the quantity of the sliver that needs to be replenished and the timing at which the sliver needs to be replenished for the plurality of spinning units.

  This makes it possible to check information related to sliver replenishment in various places, as compared with a configuration in which the display unit or the like of the pneumatic spinning machine is checked.

  In the pneumatic spinning machine, the control unit stores a stop length that is a threshold value regarding the remaining length of the sliver, and when the remaining length of the sliver becomes equal to or less than the stop length, It is preferable to stop the supply device.

  Thereby, it can prevent that spun yarn is produced | generated from the sliver near the edge part with a possibility that quality may be low.

  The pneumatic spinning machine preferably has the following configuration. That is, the supply device is a draft device that drafts a sliver guided by the guide device into a fiber bundle. The conveying rollers are a plurality of draft rollers and a plurality of counter rollers provided in the draft device. The plurality of opposed rollers provided in each of the two adjacent spinning units are pressed toward the plurality of draft rollers, or the plurality of draft rollers provided in each of the two adjacent spinning units are provided as the plurality of opposed rollers. A draft device cradle that presses toward The control unit is in a state where the draft device cradle is pressing the draft roller or the opposing roller, and the draft device of the two spinning units holds the sliver, The draft device of the spinning unit is stopped.

  As a result, since the drafting device is stopped while one spinning unit is holding the sliver, the spinning operation can be resumed without releasing the pressing of the drafting device cradle. Therefore, since the spinning operation by one spinning unit can be resumed while continuing the spinning operation of the other spinning unit, it is possible to prevent a decrease in production efficiency.

  The pneumatic spinning machine preferably has the following configuration. That is, the pneumatic spinning machine includes a sliver storage unit and a package placement unit. The sliver stored by the guide device is stored in the sliver storage unit. On the package placement portion, a package in which the spun yarn spun by the pneumatic spinning device has been wound is placed. In a plan view, the package placement unit, the spinning unit, the guide device, and the sliver storage unit are arranged in this order in a direction perpendicular to the parallel direction of the spinning units, and the package placement unit is used as a reference. A passage extending along the parallel direction is formed on the opposite side of the spinning unit.

  In the above layout, since the sliver storage part is disposed on the opposite side of the passage with respect to the spinning unit, it is difficult for an operator who normally works in the passage to visually check the remaining length of the sliver. Therefore, the sliver is often replenished after the sliver runs out, and the production efficiency is lowered. In this regard, the use of the present invention makes it easy for the operator to grasp the sliver consumption length even in the above layout. As a result, there is a high possibility that the sliver can be replenished before the sliver runs out, so that production efficiency can be increased.

  The pneumatic spinning machine preferably has the following configuration. That is, this pneumatic spinning device includes a nozzle block and a hollow guide shaft body. The nozzle block twists the fiber bundle by injecting air to generate a swirling flow in the spinning chamber. The hollow guide shaft body guides the fiber bundle that has been twisted in the spinning chamber to the outside.

  In general, the above-mentioned type of pneumatic spinning machine has a high spinning speed. Therefore, a spinning unit that temporarily stops spinning for some reason has a longer sliver consumption length than other spinning units. Is greatly reduced. As a result, the sliver replenishment timing is greatly different among the plurality of spinning units, so that the effects of the present invention can be exhibited more effectively.

  The pneumatic spinning machine preferably includes a reset operation unit capable of performing an operation of resetting a calculation result of the consumption length of the sliver calculated by the control unit.

  Thus, for example, by operating the reset operation unit after replenishing the sliver, the consumption length of the sliver after replenishment can be accurately calculated.

  In the pneumatic spinning machine, a sensor that detects a rotation amount of the transport roller or a length by which the sliver is sent between an upstream end portion of the supply device and an upstream end portion of the guide device. It is preferable that it is not provided.

  Thereby, since the sensor as described above is not provided, the configuration of the pneumatic spinning machine can be simplified and the cost can be further reduced.

  According to the third aspect of the present invention, the following sliver supplement information display control method is provided. In other words, this sliver replenishment information display control method causes the external device arranged to be communicable with the pneumatic spinning machine to perform the following reception process and display process. In the receiving step, at least one of the consumption length of the sliver calculated based on the instruction signal and information calculated based on the consumption length of the sliver is received. In the display step, the content received in the reception step is displayed on the external device.

  Accordingly, information useful for sliver replenishment can be displayed on the external device, so that the sliver can be replenished efficiently by the operator carrying the external device.

  Next, a spinning machine according to an embodiment of the present invention will be described with reference to the drawings. In this specification, “upstream” and “downstream” mean upstream and downstream in the fiber travel direction.

  As shown in FIG. 1, the spinning machine (pneumatic spinning machine) 1 includes a plurality of spinning units 2 arranged side by side, a yarn splicing cart 41, a doffing cart 42, and a prime mover box 43.

  Inside the prime mover box 43, a machine control unit 101 is arranged. The machine control unit 101 controls a plurality of spinning units 2. The prime mover box 43 includes a machine base display unit (first display unit) 50. The machine base display unit 50 displays information on the operation status and / or yarn quality of each spinning unit 2 by an appropriate operation of the operator. The machine base control unit 101 can transmit the above information to the portable terminal (external device) 200 carried by the operator via the antenna (transmission unit) 103. The machine base control unit 101 may transmit the above information to a drawing machine that is a machine in the previous process of the spinning machine 1. The machine base display unit 50 and the machine base control unit 101 may be provided in addition to the motor box 43.

  The mobile terminal 200 is a smartphone, a tablet terminal, a wearable terminal, or the like, and includes at least a communication unit that performs wireless communication with the spinning machine 1 and a display unit that displays predetermined information. The portable terminal 200 may be a general-purpose machine that can execute various applications, or may be a dedicated machine (embedded machine) that executes only applications related to textile machines such as the spinning machine 1.

  As shown in FIG. 2, each spinning unit 2 includes, in order from the upstream to the downstream, a sliver storage unit (sliver kens) 5, a plurality of guide devices 6, a draft device (feed device) 7, and an air spinning device 9. And a yarn storage device 12 and a winding device 13. The draft device 7 drafts the fiber bundle 8 while feeding the sliver 15 of the sliver storage unit 5. The fiber bundle 8 supplied by the draft device 7 is spun by an air spinning device 9. The spun yarn 10 delivered from the pneumatic spinning device 9 passes through a yarn clearer 49 described later, and further passes through the yarn storage device 12. Then, the wound yarn 13 is wound around the bobbin 48 by the winding device 13, whereby the package 28 is formed.

  The guide device 6 guides the sliver 15 stored in the sliver storage unit 5 toward the draft device 7. The guide device 6 is a roller-shaped member, and a guide portion that guides the sliver 15 in the width direction is provided along a direction parallel to the fiber traveling direction. In this embodiment, the drive part which drives the guide apparatus 6 is not provided, but when the downstream draft device 7 pulls the sliver 15, the sliver 15 is conveyed downstream. A drive unit that drives the guide device 6 may be provided.

  The draft device 7 sandwiches and transports the sliver 15 supplied from the guide device 6 between a plurality of draft rollers (bottom rollers, transport rollers) and a plurality of opposing rollers (top rollers, transport rollers). The fiber bundle 8 is drawn (drafted) until it reaches a predetermined fiber amount (or thickness). The draft device 7 includes four draft rollers, a back roller 16, a third roller 17, a middle roller 19, and a front roller 20, in order from the upstream side. A rubber apron belt 18 is wound around the middle roller 19. Each draft roller is rotationally driven at a predetermined rotational speed.

  In the two adjacent spinning units 2, the shafts of the opposing rollers are connected to each other and supported by the draft device cradle 21. The draft device cradle 21 is configured to change its position between a state in which the opposing roller is pressed against the draft roller and a state in which the opposing roller is separated from the draft roller. The draft device 7 can be cleaned by separating the opposed roller from the draft roller. The draft device cradle 21 may be configured to support a draft roller instead of a counter roller.

  As shown in FIG. 4, the draft device 7 includes a first motor 81 that drives the back roller 16, a second motor 82 that drives the third roller 17, a third motor 83 that drives the middle roller 19, and a front roller. And a fourth motor 84 that drives the motor 20. Since the first motor 81 to the fourth motor 84 of the present embodiment are provided for each spinning unit 2, the presence / absence of rotation of the draft roller and the rotation speed can be changed for each spinning unit 2.

  The draft device 7 serves as a motor driver for driving the first motor (electric motor) 81 to the fourth motor 84, respectively, and includes a first motor control unit 85, a second motor control unit 86, and a third motor control unit 87. And a fourth motor control unit 88. The first motor 81 to the fourth motor 84 are controlled by a unit control unit 102 provided for each spinning unit 2. Instead of being provided for each spinning unit 2, one unit control unit 102 may be provided for each of the plurality of spinning units 2.

  Specifically, for example, the first motor 81 is a step motor, and is based on the number of pulses (the number of pulses instructing the rotation of the first motor 81) input from the unit control unit 102 to the first motor control unit 85. The amount of rotation (number of rotations and angle of rotation) is controlled. Therefore, the number of rotations per unit time of the first motor 81 can be controlled by changing the number of pulses input per unit time. The unit controller 102 can determine the number of rotations of the first motor 81 based on the number of pulses (instruction signal) instructing the rotation of the first motor 81. The number of rotations can be similarly determined for the second motor 82 to the fourth motor 84. For this reason, in this embodiment, a sensor that detects the number of rotations of the draft roller (in particular, the back roller 16 that is the transport roller arranged on the most upstream side in the fiber traveling direction) and the sliver 15 that is guided by the guide device 6. It does not have a sensor to detect In other words, the spinning machine 1 does not include a sensor that directly or indirectly detects the running length of the fiber from the sliver storage unit 5 (that is, from the guide device 6) to the draft device 7.

  The pneumatic spinning device 9 generates the spun yarn 10 using the fiber bundle 8 supplied from the draft device 7. Specifically, as shown in FIG. 3, the pneumatic spinning device 9 includes a first holder (nozzle block) 60 and a second holder 70. The first holder 60 is disposed at the upstream end of the pneumatic spinning device 9. The first holder 60 includes a fiber guide 61, a spinning chamber 62, and a nozzle 63.

  The fiber guide 61 guides the fiber bundle 8 drafted by the draft device 7 toward the inside of the pneumatic spinning device 9. The fiber guide 61 is formed with a fiber introduction port 61a and a guide needle 61b. The fiber bundle 8 drafted by the draft device 7 is introduced from the fiber introduction port 61a and guided into the spinning chamber 62 so as to be wound around the guide needle 61b. The air spinning device 9 ejects air from the nozzle 63 into the spinning chamber 62, and causes a swirling air flow to act on the fiber bundle 8 in the spinning chamber 62. The guide needle 61b may be omitted, and the downstream end of the fiber guide 61 may have the function of the guide needle 61b.

  The second holder 70 includes a hollow guide shaft body 71. A thread passage 72 is formed at the center of the hollow guide shaft 71. The rear end of the fiber of the fiber bundle 8 is swung around the front end of the hollow guide shaft 71 by the air jetted from the nozzle 63. Thus, the twisted fiber bundle 8 is sent out of the air spinning device 9 from the downstream yarn outlet (not shown) through the yarn passage 72.

  A yarn accumulating device 12 is provided downstream of the pneumatic spinning device 9. As shown in FIG. 2, the yarn storage device 12 includes a yarn storage roller 26.

  The yarn storage roller 26 can temporarily store a predetermined amount of the spun yarn 10 around its outer peripheral surface. When the spun yarn 10 is wound around the outer peripheral surface of the yarn accumulating roller 26, the yarn accumulating roller 26 is rotated at a predetermined rotation speed, whereby the spun yarn 10 is pulled out from the air spinning device 9 at a predetermined speed and downstream. Can be transported. Since the spun yarn 10 can be temporarily stored on the outer peripheral surface of the yarn storage roller 26, the yarn storage device 12 can function as a kind of buffer. As a result, the problem that the spinning speed in the pneumatic spinning device 9 and the winding speed (traveling speed of the spun yarn 10 wound on the package 28) do not coincide with each other for some reason (for example, loosening of the spun yarn 10) is eliminated. be able to. Instead of the yarn accumulating device 12, a delivery roller and a nip roller may be provided so that the spun yarn 10 is pulled out from the pneumatic spinning device 9 by the roller pair. Alternatively, a delivery roller and a nip roller may be provided between the air spinning device 9 and the yarn storage device 12. When the delivery roller and the nip roller are provided, a slack tube that temporarily stores the spun yarn 10 with air may be provided downstream of the roller pair instead of the yarn storage device 12.

  A yarn guide 25 and a winding device 13 are disposed downstream of the yarn storage device 12. A waxing device may be provided between the yarn guide 25 and the winding device 13, and wax may be applied to the spun yarn 10.

  The winding device 13 includes a cradle arm 46, a winding drum 98, and a traverse guide 99. The cradle arm 46 rotatably supports a bobbin 48 for winding the spun yarn 10. The winding drum 98 rotates while being in contact with the bobbin 48 or the outer peripheral surface of the package 28 by transmitting the driving force of a winding drum drive motor (not shown). The take-up drum drive motor is provided in common for the plurality of spinning units 2, for example, and is provided in the prime mover box 43. The traverse guide 99 can engage the spun yarn 10. The winding device 13 drives the winding drum 98 by a winding drum drive motor while reciprocating the traverse guide 99 by a driving means (not shown). Accordingly, the winding device 13 rotates the package 28 that contacts the winding drum 98 and winds the spun yarn 10 around the package 28 while traversing the spun yarn 10.

  Each spinning unit 2 includes a unit display panel 53. The unit display panel 53 includes a notification lamp (notification unit) 54, a unit display unit (second display unit) 55, and a reset operation unit 56. For example, the notification lamp 54 is normally turned off (non-notification state) and is turned on when an abnormality requiring operator intervention occurs in the spinning unit 2 (notification state). The notification lamp 54 is lit at both the normal time and the abnormal time, and the color may be different between the normal time and the abnormal time. The notification lamp 54 may be configured to be off or lit during normal times and blink when abnormal. The operator can know the occurrence of abnormality by visually confirming the state of the notification lamp 54. The unit display unit 55 is a segment display, and displays information regarding an abnormality, an error code, and the like when an abnormality occurs. The reset operation unit 56 is a button or the like for resetting a calculation result (integrated length) of a consumption length of a sliver 15 described later.

  As illustrated in FIGS. 1 and 2, the yarn joining cart 41 includes a yarn joining device 93, a suction pipe 94, and a suction mouth 95. When yarn breakage or yarn cut occurs in a spinning unit 2, the yarn splicing carriage 41 travels on a rail (not shown) and stops at or near the spinning unit 2. The suction pipe 94 rotates upward about the shaft, captures the spun yarn 10 delivered from the pneumatic spinning device 9, and rotates downward about the shaft to rotate the spun yarn 10 into the yarn. Guide to the relay device 93. The suction mouse 95 rotates downward about the shaft, captures the spun yarn 10 from the package 28, and guides the spun yarn 10 to the yarn joining device 93 by rotating upward about the shaft. To do. The yarn joining device 93 performs yarn joining between the guided spun yarns 10. Thereby, the winding device 13 can resume winding the spun yarn 10.

  The doffing carriage 42 performs a bobbin setting operation for supplying a bobbin 48 to the cradle arm 46 to prepare for winding the spun yarn 10, and a doffing operation for removing the full package 28 from the cradle arm 46. Do. When the doffing carriage 42 receives an instruction to perform a bobbin setting operation and / or a doffing operation on a certain spinning unit 2, the doffing carriage 42 travels to the spinning unit 2 on the traveling path outside the region where the spinning units 2 are arranged side by side. Run. The doffing carriage 42 stops in front of the spinning unit 2 that has received the instruction, and performs bobbin setting work or doffing work (or both work). The package 28 doffed by the doffing cart 42 is placed on the package placement unit 47.

  In the present embodiment, the package mounting portion 47 has a function as a conveyor, and the package 28 is transported along the direction in which the spinning units 2 are arranged and automatically sent to the next process. However, the package mounting unit 47 may be configured not to have a conveyor function, and the package 28 on the package mounting unit 47 may be manually collected by the operator. The doffing operation is performed as described above.

  A passage 44 through which an operator passes is provided on the opposite side of the spinning unit 2 with the package placement portion 47 interposed therebetween. In other words, the passage 44 is provided on the front side of the spinning machine 1 (for example, the side on which the machine display unit 50 or the unit display panel 53 is disposed) (the machine front side).

  In the spinning machine 1, the sliver storage portion 5 is disposed on the rear side of the machine (right side in FIG. 2), and a passage 44 is provided on the opposite side of the machine front side (left side in FIG. 2). In the meantime, the passage 44, the spinning unit 2, the guide device 6, and the sliver storage part 5 are arranged in this order from the machine front side. Thus, since many members are arrange | positioned between the channel | path 44 and the sliver storage part 5, when passing the channel | path 44, an operator confirms the remaining length of the sliver 15 of the sliver storage unit 5 directly visually. Since this is not possible, there is a problem that it is difficult to understand the timing of refilling the sliver 15. The spinning machine 1 of the present embodiment has a configuration for making it easy for an operator to check the remaining length of the sliver 15.

  Next, with reference to FIGS. 5 to 9, calculation processing and display processing of information relating to replenishment of the sliver 15 will be described. These processes are performed by the machine control unit 101, the unit control unit 102, and the portable terminal 200. In the following description, the machine base control unit 101 and the unit control unit 102 may be collectively referred to as the control unit 100. In the following description, the entire operation for generating the package 28 from the sliver 15 is referred to as “spinning operation”. In other words, the spinning operation is an operation including drafting by the draft device 7 and spinning by the air spinning device 9.

  First, processing performed by the unit control unit 102 will be described with reference to the flowcharts of FIGS. 5 and 6. As described above, the unit controller 102 can acquire the cumulative number of rotations of the first motor 81 based on the number of pulses transmitted to the first motor controller 85 to instruct the rotation of the back roller 16. . Since the ratio of the number of rotations of the first motor 81 and the back roller 16 is determined, the total number of rotations of the back roller 16 can be calculated (acquired) based on the total number of rotations of the first motor 81 (S101). . When the ratio of the number of rotations of the back roller 16 and the first motor 81 is 1, the total number of rotations of the first motor 81 is equal to the total number of rotations of the back roller 16.

  Next, the unit controller 102 calculates the consumption length of the sliver 15 based on the cumulative number of rotations of the back roller 16 acquired in step S101 (S102). Specifically, the unit control unit 102 multiplies the cumulative number of rotations of the back roller 16 by the diameter and circumference ratio of the back roller 16 to obtain the length of the sliver 15 sent out by the back roller 16 (that is, the sliver 15 Consumption length). In consideration of the slip between the sliver 15 and the back roller 16, a correction coefficient or the like may be further multiplied.

  Next, the unit control unit 102 calculates the consumption length of the sliver 15 calculated in step S102, the set value of the fiber travel speed (set travel speed of any one of the sliver 15, the fiber bundle 8, and the spun yarn 10), and the sliver. 15 initial length information. The amount of the sliver 15 stored in each sliver storage unit 5 is basically the same length in the full state that is the state before the consumption of the sliver 15 by each spinning unit 2 is started. Therefore, the initial length information of the sliver 15 is a constant value. The set value of the fiber traveling speed and the initial length information of the sliver 15 are input in advance by the operator and stored in the machine base control unit 101 or the unit control unit 102. The machine base control unit 101 may be configured to acquire such information by communicating with other devices. For example, the initial length information of the sliver 15 may be obtained from the storage unit of the sliver storage unit 5 or the drawing machine.

  The unit control unit 102 calculates the remaining length of the sliver 15 and the remaining time until the sliver 15 runs out based on the cumulative number of rotations of the back roller 16, the set value of the fiber traveling speed, and the initial length information of the sliver 15. Calculate (S103). The remaining length of the sliver 15 can be calculated by subtracting the consumed length of the sliver 15 from the initial length information of the sliver 15. Moreover, since the consumption length of the sliver 15 per unit time can be calculated by using the set value of the fiber traveling speed, the remaining time until the sliver 15 runs out can be calculated. Instead of the set value of the fiber traveling speed, the fiber traveling speed (for example, the average traveling speed of the sliver 15 in the past predetermined time) may be calculated based on the rotational speed of the back roller 16 and used for the process of step S103. good.

  The unit control unit 102 displays the remaining length or remaining time of the sliver 15 calculated in step S103 on the unit display unit 55 as shown in FIG. 9 (S104). Since the unit display unit 55 is a segment display, it displays a number corresponding to the remaining length or the remaining time. When displaying the remaining length, the remaining length may be indicated by a specific numerical value (for example, “2” meters), or the remaining length may be indicated by a ratio (for example, “15”%) to the initial length. May be. Further, the remaining time may be indicated instead of the remaining length. When the number of digits that can be displayed by the unit display unit 55 is large, or when the unit display unit 55 is a dot matrix type display, both the remaining length and the remaining time can be displayed. The unit display unit 55 may be configured to be able to switch which of the remaining length and the remaining time is displayed.

  Next, the unit controller 102 determines whether the remaining length calculated in step S103 is equal to or less than the stop length (S105). This stop length is a numerical value for defining the timing for stopping the spinning operation. Conventionally, when the sliver 15 disappears, the spinning operation is stopped by detecting that the fiber bundle 8 is no longer supplied to the pneumatic spinning device 9 or that the spun yarn 10 is not sent from the pneumatic spinning device 9. . In this case, when the sliver 15 is replenished and the spinning operation is resumed, an operation of placing the sliver 15 on the guide device 6 is required. Further, since the draft device cradle 21 supports the opposing rollers of the two spinning units 2 together as described above, the sliver 15 is set in the draft device 7 with the opposing rollers separated from the draft roller. It is necessary to redo. Therefore, it is necessary to stop the spinning operation of the adjacent spinning unit 2. In contrast, in the present embodiment, the spinning operation is stopped when the remaining length is equal to or less than the stop length (S106). As the stop length, a value is set such that the upstream end of the sliver 15 becomes upstream of the guide device 6 (that is, upstream of the draft device 7) after the spinning operation is stopped. Thereby, the operation | work which passes the sliver 15 to the guide apparatus 6 (operation to pass) and the operation | work which operates the draft apparatus cradle 21 become unnecessary, and an operator's effort can be reduced. In addition, the spinning operation can be quickly restarted by reducing the labor of the operator, and it is not necessary to stop the spinning operation of the adjacent spinning unit 2, so that the production efficiency can be improved. Processing after stopping the spinning operation will be described later.

  When the calculated remaining length is longer than the stop length, the unit controller 102 determines whether or not the remaining length is equal to or shorter than the notice length (predetermined length) (S107). The notice length is longer than the stop length and is a length for determining the timing for prompting the operator to refill the sliver 15. If the calculated remaining length is equal to or shorter than the notice length, the unit controller 102 turns on the notification lamp 54 (S108). At this time, an error code indicating that the sliver 15 is small may be displayed on the unit display section 55. Further, in addition to or instead of the notification lamp 54, a notification sound may be generated. Instead of the process of lighting the notification lamp 54 based on the remaining length, the notification lamp 54 may be turned on when the remaining time is equal to or shorter than the notice time (predetermined time).

  Next, the unit control unit 102 transmits the calculated remaining length and remaining time of the sliver 15 to the machine base control unit 101 (S109). The transmission in step S109 may be wired or wireless. Thereafter, the unit control unit 102 performs the process of step S101 again.

  Hereinafter, the process performed by the unit control unit 102 after the spinning operation is stopped will be described with reference to FIG. After stopping the spinning operation, the unit control unit 102 determines whether or not the reset operation unit 56 has been operated (S110). The unit control unit 102 resets the consumption length of the sliver 15 when the reset operation unit 56 is operated. Accordingly, when the reset operation unit 56 is operated after the sliver 15 is replenished, the unit control unit 102 can appropriately calculate the consumption length of the sliver 15 in consideration of the sliver 15 replenishment. Specifically, the consumption length of the sliver 15 managed by the unit control unit 102 becomes 0, and the remaining length of the sliver 15 matches the initial length information of the sliver 15.

  The quality of the sliver 15 remaining in the sliver reservoir 5 after the spinning operation is stopped may be poor. Therefore, the operator discards the remaining sliver 15 and connects the downstream end of the replenished sliver 15 to the sliver 15 set in the spinning unit 2 at a position upstream of the guide device 6. The operator does not have to discard the remaining sliver 15.

  Next, the unit controller 102 determines whether or not there is an instruction to resume the spinning operation (S112). When there is an instruction to resume the spinning operation, the unit control unit 102 resumes the spinning operation (S113), and performs the process of step S101 again. If there is no resumption instruction for the spinning operation, the unit control unit 102 waits until there is a resumption instruction.

  Hereinafter, the process performed by the machine base control unit 101 will be described with reference to FIG.

  The machine control unit 101 acquires (receives) the information (specifically, the remaining length and remaining time of the sliver 15 of each spinning unit 2) transmitted by the unit control unit 102 in step S109 described above (S201). .

  Next, the machine base control unit 101 selects the shortest remaining time by comparing the remaining times received from the unit control units 102 of the plurality of spinning units 2, and as shown in FIG. Is displayed on the machine base display unit 50 as “time until” (S202). The operator can grasp the timing when the sliver 15 needs to be replenished by viewing this display.

  Next, the machine control unit 101 displays information indicating the spinning unit 2 for which the remaining time selected and displayed in step S202 is calculated on the machine display unit 50 (S203). The operator can grasp the spinning unit 2 that needs to be replenished with the sliver 15 next by viewing this display. Note that not only the spinning unit 2 with the shortest remaining time but also the spinning unit 2 that needs to be replenished with the sliver 15 within a predetermined time may be displayed on the machine display unit 50.

  Next, the machine base control unit 101 calculates the total quantity (for example, the number of sliver storage units) of the sliver 15 that needs to be replenished within a predetermined time based on the acquired remaining time, and the machine base display unit 50 (S204). The operator can grasp how much sliver 15 is necessary by viewing this display.

  Next, the machine control unit 101 displays information displayed on the machine display unit 50 (specifically, a time until replenishment is necessary, information indicating the spinning unit 2 that needs to be replenished, a predetermined time) The total number of slivers that need to be replenished within (S205) is transmitted to the portable terminal 200 via the antenna 103 (S205). The information to be transmitted to the portable terminal 200 may be one or two of the above three information, or information for each spinning unit 2 acquired from the unit control unit 102 by the machine base control unit 101. There may be. Further, the information to be transmitted to the mobile terminal 200 may be information separately calculated for transmission to the mobile terminal 200 as long as it is sliver supplement information that is information related to the replenishment of the sliver 15. The operator can grasp the required quantity of the sliver 15 by viewing this display. The transmission timing from the machine base control unit 101 to the portable terminal 200 may be, for example, every time the content of information displayed on the machine display unit 50 is updated as shown in FIG. It may be a case of receiving, or any other timing.

  Hereinafter, the process performed by the mobile terminal 200 will be described with reference to FIG.

  The portable terminal 200 receives information displayed on the machine display unit 50 from the machine control unit 101 (specifically, information indicating the time until replenishment is required, and the spinning unit 2 that needs to be replenished next, The total number of slivers that need to be replenished within a predetermined time) is received (S301, receiving step).

  Next, the mobile terminal 200 displays the information received from the machine control unit 101 on the display screen of the mobile terminal 200 (S302, display process). The operator can grasp the consumption status of the sliver 15 without looking at the machine base display unit 50 and the unit display panel 53 by carrying the mobile terminal 200, so that the sliver 15 can be replenished more efficiently. It can be carried out.

  As described above, the information transmitted by the machine base control unit 101 may be other information. In this case, the mobile terminal 200 displays information other than the above. The portable terminal 200 may be configured to receive and store various information regarding the replenishment of the sliver 15 included in the machine base control unit 101 and display information according to the operation of the operator. The portable terminal 200 may be configured to access the machine base control unit 101 and acquire corresponding information in accordance with the operation of the operator.

  As described above, the spinning machine 1 of this embodiment includes the guide device 6, the draft device 7, the pneumatic spinning device 9, the first motor 81, and the control unit 100. The guide device 6 guides the sliver 15. The draft device 7 includes a back roller 16 that sends a sliver 15 guided by the guide device 6, and supplies the sliver 15 as a fiber bundle 8. The air spinning device 9 generates a spun yarn 10 by twisting the fiber bundle 8 supplied by the draft device 7 by an air flow. The first motor 81 drives the back roller 16, and the amount of rotation is controlled according to an instruction signal (specifically, the number of pulses). The control unit 100 calculates the consumption length of the sliver 15 based on the instruction signal.

  Thereby, the consumption length of the sliver 15 can be calculated without using a sensor that directly detects the amount of rotation such as a draft roller. Therefore, it is possible to avoid complication and cost increase of the spinning machine 1 by adding a sensor. In addition, since the calculation is performed based on the rotation amount of the draft roller that sends the sliver 15, the consumption length of the sliver 15 is accurately calculated as compared with the method of calculating the consumption length of the sliver 15 using the spinning speed or the like. it can.

  The spinning machine 1 according to this embodiment includes a plurality of spinning units 2 each having at least a draft device 7 and an air spinning device 9.

  In the spinning machine 1 including a plurality of spinning units 2, it is difficult for an operator to grasp the consumption length of the sliver 15 of each spinning unit 2, and thus the effect of the present invention can be exhibited more effectively.

  In the spinning machine 1 of the present embodiment, the control unit 100 performs a process of calculating the remaining length of the sliver 15 based on the consumption length of the sliver 15. The control unit 100 can control the draft device 7 to stop for each spinning unit 2 based on the calculated remaining length of the sliver 15. In this control, the upstream end of the sliver 15 in the fiber running direction is controlled. The draft device 7 is stopped so that it is positioned upstream from the guide device 6.

  Thereby, for example, when the sliver 15 is replenished (sliver cans replacement), the operation of setting the sliver 15 to the guide device 6 becomes unnecessary, so that the sliver 15 can be replenished in a short time, and the entire spinning machine 1 is operated. Reduced efficiency can be avoided.

  In the spinning machine 1 of the present embodiment, the control unit 100 determines the remaining time until the sliver 15 disappears in any of the plurality of spinning units 2, based on the initial length information of the sliver 15 and the fiber traveling speed, and Then, at least one of the total quantity of the sliver 15 that needs to be replenished within a predetermined time is calculated.

  Thereby, since the information which assists the replenishment of the sliver 15 is calculated, for example, replenishment of the sliver 15 can be performed efficiently.

  The spinning machine 1 according to the present embodiment includes a machine display unit 50 that displays information related to a plurality of spinning units 2. The machine display unit 50 displays at least one of the remaining time until the sliver 15 runs out in any of the plurality of spinning units 2 and the total quantity of the sliver 15 that needs to be replenished within a predetermined time.

  As a result, an operator who replenishes the sliver 15 can easily replenish the sliver 15 or complete the replenishment before the sliver 15 runs out by checking the display on the machine base display unit 50.

  The spinning machine 1 of the present embodiment includes a notification lamp 54 that is individually disposed in the spinning unit 2 and configured to be switchable between a notification state and a non-notification state. The notification lamp 54 is used when the remaining length of the sliver 15 of the spinning unit 2 is equal to or less than the notice length for the spinning unit 2 in which the notification lamp 54 is arranged, and when the current sliver 15 is used. When the remaining spinning time becomes equal to or shorter than the notice time, the notification state is switched to at least one of them.

  As a result, the operator who replenishes the sliver 15 identifies the spinning unit 2 that needs replenishment of the sliver 15 by confirming the notification content of the notification lamp 54 (whether it is lit, lighting color, flashing, etc.). Therefore, the sliver 15 can be replenished efficiently.

  The spinning machine 1 of the present embodiment includes a unit display unit 55 that is individually arranged in the spinning unit 2 and can display at least numerals. The unit display unit 55 displays at least one of the remaining length of the sliver 15 and the remaining time until the sliver 15 runs out for the spinning unit 2 in which the unit display unit 55 is arranged.

  Thereby, since the usage status of the sliver 15 of each spinning unit 2 is displayed in detail, the operator who replenishes the sliver 15 can efficiently replenish the sliver 15 by checking this display.

  The spinning machine 1 of the present embodiment includes an antenna 103 that transmits at least one of the quantity and timing of the sliver 15 that needs to be supplemented to the plurality of spinning units 2.

  Thereby, compared with the structure which confirms the display part etc. of the spinning machine 1, the information regarding the replenishment of the sliver 15 can be confirmed in various places.

  The control unit 100 of the spinning machine 1 according to the present embodiment stores a stop length that is a threshold value regarding the remaining length of the sliver 15, and the draft device when the remaining length of the sliver 15 becomes equal to or less than the stop length. 7 is stopped.

  Thereby, it can prevent that the spun yarn 10 is produced | generated from the sliver 15 of the edge part vicinity with a possibility that quality may be low.

  The fine spinning machine 1 according to the present embodiment presses a plurality of opposed rollers provided in two adjacent spinning units 2 toward a plurality of draft rollers, or a plurality of draft rollers provided in two adjacent spinning units 2 respectively. Is provided with a draft device cradle 21 that presses the roller toward a plurality of opposed rollers. The control unit 100 is in a state where the draft device cradle 21 presses the draft roller and the draft device 7 of the two spinning units 2 holds the sliver 15, and The draft device 7 is stopped.

  As a result, the drafting device 7 stops while the spinning unit 2 is holding the sliver 15, so that the spinning operation can be resumed without releasing the pressing of the draft device cradle 21. Accordingly, since the spinning operation by one spinning unit 2 can be resumed while continuing the spinning operation of the other spinning unit 2, it is possible to prevent a decrease in production efficiency.

  The spinning machine 1 of the present embodiment includes a sliver storage unit 5 and a package placement unit 47. A sliver 15 guided by the guide device 6 is stored in the sliver storage unit 5. A package on which the spun yarn 10 spun by the pneumatic spinning device 9 has been wound is placed on the package placement portion 47. In a plan view, the package placement unit 47, the spinning unit 2, the guide device 6, and the sliver storage unit 5 are arranged in this order in the direction perpendicular to the direction in which the spinning units 2 are arranged in parallel, and the package placement unit 47 is used as a reference. A passage extending along the parallel direction is formed on the opposite side of the spinning unit 2.

  In the above layout, since the sliver reservoir 5 is disposed on the opposite side of the passage with respect to the spinning unit 2, it is difficult for an operator working in the passage to visually check the remaining length of the sliver 15. Easy to be. Therefore, the sliver 15 is often replenished after the sliver 15 is lost, and the production efficiency is lowered. In this regard, by using the present invention, the operator can easily grasp the consumption length of the sliver 15 even in the above-described layout. As a result, there is a high possibility that the sliver 15 can be replenished before the sliver 15 disappears, so that the production efficiency can be increased.

  The spinning machine 1 according to the present embodiment includes a first holder 60 and a hollow guide shaft body 71. The first holder 60 twists the fiber bundle 8 by injecting air to generate a swirling flow in the spinning chamber 62. The hollow guide shaft body 71 guides the fiber bundle 8 twisted in the spinning chamber 62 to the outside (the outside of the hollow guide shaft body 71, that is, the outside of the pneumatic spinning device 9).

  In general, the spinning machine 1 of the type described above has a high spinning speed. Therefore, the spinning unit 2 that temporarily stops the spinning operation for some reason is compared with the other spinning units 2 in the sliver 15. The consumption length is significantly reduced. As a result, since the replenishment timing of the sliver 15 is greatly different among the plurality of spinning units 2, the effect of the present invention can be exhibited more effectively.

  The spinning machine 1 of the present embodiment includes a reset operation unit 56 that can perform an operation of resetting the calculation result of the consumption length of the sliver 15 calculated by the control unit 100.

  Thereby, for example, by operating the reset operation unit 56 after replenishing the sliver 15, the consumption length of the sliver 15 after replenishment can be accurately calculated.

  In the spinning machine 1 of the present embodiment, a sensor that detects the rotation amount of the draft roller or the length by which the sliver 15 is sent between the upstream end of the draft device 7 and the upstream end of the guide device 6 is provided. Not provided.

  Thereby, since the sensor as described above is not provided, the configuration of the spinning machine 1 can be simplified and the cost can be further reduced. Since there is no situation where the spinning operation of the spinning machine 1 is stopped due to the sensor maintenance and replacement due to failure as described above, the operation efficiency of the spinning machine 1 is not lowered.

  The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

  In the above embodiment, the hardware that generates a pulse that instructs the rotation of the back roller 16 and the hardware that calculates the cumulative number of rotations based on the number of pulses are the same, but may be different.

  In the above-described embodiment, the first motor 81 to the fourth motor 84 are provided for each spinning unit 2. However, a configuration may be adopted in which the draft rollers of the plurality of spinning units 2 are driven by a common motor. In this configuration, the rotational speeds of the draft rollers of each spinning unit 2 are all the same. Further, in this configuration, it is possible to switch the rotation of the draft roller for each spinning unit 2 by switching between transmission and non-transmission of power from the motor to the draft roller using the clutch. Therefore, in this configuration, the sliver consumption length can be calculated based on the rotation amount of the draft roller and the operation state of the clutch. For example, the third motor 83 and the fourth motor 84 may be provided in common for the plurality of spinning units 2 and disposed in the prime mover box 43.

  In the above embodiment, the notification by the notification lamp 54 and the display by the unit display unit 55 are performed based on the remaining length of the sliver 15, but may be performed based on the remaining time until the sliver 15 runs out.

  In the above embodiment, the consumption length of the sliver 15 is calculated based on the number of pulses for rotating the first motor 81 that drives the back roller 16, but other draft rollers (third roller 17, The length of consumption of the sliver 15 may be calculated based on the number of pulses for rotating the motor that drives the middle roller 19 and the front roller 20).

  In the above embodiment, the consumption length of the sliver 15 is detected based on the number of pulses instructing the rotation of the first motor 81. Instead, as shown in FIG. 11, a rotation sensor 89 that detects the rotation amount of the back roller 16 is provided, and the total number of rotations of the back roller 16 can be calculated based on the detection result of the rotation sensor 89. . As shown in FIG. 11, when the back roller 16 and the third roller 17 are driven by the first motor 81, the back roller 16 and the third roller 17 have different rotation speeds, but the ratio of the number of rotations is fixed. Rotate synchronously. Therefore, the rotation amount of the back roller 16 can be accurately estimated by detecting the rotation amount of the third roller 17. Therefore, the spinning machine 1 may include a sensor that detects the rotation amount of the third roller 17 instead of the sensor that detects the rotation amount of the back roller 16. Alternatively, a gear that transmits power from the output shaft of the first motor 81 to the drive shaft of the back roller 16 or the third roller 17 also rotates in synchronization with the back roller 16, so that the number of rotations of the gear is detected. May be.

  In the above embodiment, the reset operation unit 56 is provided on the passage 44 side (machine front side) of the spinning unit 2. And in the vicinity of the guide device 6). Thereby, after the replenishment work of the sliver 15, the operator can operate the reset operation unit 56 without moving to the front side of the machine. The spinning machine 1 may be configured such that when the spinning operation is stopped because the remaining length of the sliver is equal to or less than the stop length, the spinning machine 1 is automatically reset after the spinning operation is resumed. .

  In the above embodiment, the process for calculating information relating to the replenishment of the sliver 15 is performed by the machine base control unit 101 or the unit control part 102. However, a part of the process described as being performed by the machine base control unit 101 is a unit. It may be performed by the control unit 102 or vice versa. For example, the machine control unit 101 may perform processing for calculating the remaining time for each spinning unit 2. Further, the unit control unit 102 may have a function of communicating with the mobile terminal 200.

  The pneumatic spinning device 9 may include a pair of air jet nozzles that twist the fiber bundle in opposite directions instead of the device having the configuration of the above embodiment.

  The pneumatic spinning device 9 of the above embodiment is an air jet spinning machine, but the present invention can also be applied to an open-end spinning machine. In the open-end spinning machine, a supply device is provided instead of the draft device. The supply device supplies the sliver guided by the guide device to an air spinning device (specifically, a fiber opening chamber for opening fibers and a spinning chamber for converging and twisting the opened fibers). It has a roller. The supply roller may be configured not to have a counter roller. By using an instruction signal that indicates the amount of rotation of the electric motor that drives the supply roller, the consumption length of the sliver can be calculated as in the above embodiment.

  In the above embodiment, the consumption length and the like of the sliver 15 are calculated based on the instruction signal (number of pulses) of the first motor 81 that is a step motor. The electric motor that drives the transport roller may be a servo motor, for example, instead of a step motor as long as the amount of rotation is controlled according to an instruction signal.

  In the above embodiment, in the height direction of the spinning machine 1, the traveling path of the spun yarn 10 from the draft device 7 to the winding device 13 when winding the package 28 is set from top to bottom, and the sliver storage section 5 was provided on the back side of the machine. However, the travel route may be set from the bottom to the top, and the sliver storage unit 5 may be disposed on the front side of the machine and below the draft device 7.
