  By the way, many yarn winding devices as disclosed in Patent Document 1 are installed in a factory, and an operator often manages a plurality of yarn winding devices. In this regard, Patent Document 1 discloses that once a malfunction occurs in the yarn winding unit (including the case where the yarn feeding bobbin is not supplied to the yarn winding unit), the yarn winding unit is operated until the operator clears the malfunction and presses the button. Does not resume. Therefore, in the configuration of Patent Document 1, for example, when the operator is working on another yarn winding unit and cannot respond immediately, the time during which the yarn winding unit cannot resume operation may become long. Led to lower efficiency.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a yarn winding unit having an automatic return function for a supply mistake of a yarn feeding bobbin.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to a first aspect of the present invention, a yarn winding unit having the following configuration is provided. That is, the yarn winding unit unwinds the yarn from the yarn feeding bobbin placed on the transport tray to form a package. The yarn winding unit includes a conveyance guide, a control unit, and a detection unit. The conveyance guide performs a supply operation of supplying the yarn feeding bobbin to a unwinding position where the yarn is unwound. The control unit controls the operation of the conveyance guide. The detection unit detects success or failure of a supply operation of the yarn feeding bobbin by the conveyance guide. When the detection unit detects that the supply operation of the yarn feeding bobbin to the unwinding position is not successful after the conveyance guide performs the supply operation, The supply operation of the conveyance guide is made to wait for a set time, and then the supply operation of the conveyance guide is performed again.

  As a result, when a yarn feeding bobbin supply error (the yarn feeding bobbin has not been supplied) occurs, the yarn feeding bobbin feeding operation in the transport guide can be automatically retried without intervention of the operator. . As a result, significant labor saving is possible. In addition, since the yarn feeding bobbin can be expected to be newly conveyed to a position where the conveyance guide can be supplied to the unwinding position while waiting without performing the supply operation, the conveyance guide Useless supply operation can be avoided.

  The yarn winding unit preferably has the following configuration. That is, the control unit performs first supply control, second supply control, and third supply control. In the first supply control, the yarn feeding bobbin is newly supplied to the unwinding position at the start of the yarn winding operation for forming the package or after the yarn unwinding from the yarn feeding bobbin is completed. Therefore, the feeding operation of the transport guide is performed. In the second supply control, immediately after the first supply control is performed, immediately after it is specified by the detection of the detection unit that the supply operation of the yarn feeding bobbin to the unwinding position is not successful, The supply operation of the transport guide is performed again. In the third supply control, after performing the second supply control, when it is specified by detection of the detection unit that the supply operation of the yarn feeding bobbin to the unwinding position is not successful, The supply operation of the conveyance guide is waited for the set time, and then the supply operation of the conveyance guide is performed again.

  As a result, the supply operation is repeated immediately after the supply bobbin supply error occurs, so that, for example, the slight catching of the yarn supply bobbin is eliminated, and the yarn supply bobbin can be supplied quickly. It can be expected to recover. If the yarn supply bobbin is not supplied even if the supply operation is immediately performed again, there is a high possibility that the supply of the yarn supply bobbin from the upstream side is stagnant. By performing the supply operation again, useless supply operation can be prevented. As described above, when a yarn feeding bobbin feeding error occurs, the feeding guide bobbin can be efficiently returned from the state where the yarn feeding bobbin is not fed to the unwinding position by repeating the feeding operation of the conveyance guide at a reasonable timing.

  In the yarn winding unit, it is preferable that the maximum number of repetitions of the third supply control that is performed after the second supply control is performed can be set.

  Thereby, even if the yarn supplying bobbin is not supplied to the unwinding position even after the third supply control is performed a predetermined number of times (that is, the yarn supplying bobbin can be successfully supplied even if the supplying operation is repeated further. If the supply operation is not performed), a wasteful supply operation of the conveyance guide can be prevented. In addition, since the number of times of repeating the supply operation can be flexibly set according to various situations, convenience can be improved.

  In the yarn winding unit, the control unit detects that the supply operation of the yarn feeding bobbin to the unwinding position has not succeeded after the third supply control has been performed the maximum number of repetitions. It is preferable to request the operator's work if it is specified by detection.

  As a result, when the supply bobbin supply error occurs, the supply operation of the conveyance guide in the yarn winding unit is automatically performed again, and the operator's work is requested when the supply fails even if it is performed a predetermined number of times. Since it is a structure, while being able to avoid calling an operator frequently, the efficiency of the whole yarn winding unit can be improved.

  The yarn winding unit preferably has the following configuration. That is, the yarn winding unit includes a display unit. The display unit displays, as a yarn feeding bobbin supply alarm, that the supply operation of the yarn feeding bobbin to the unwinding position was not successful after the second supply control was performed. After the third supply control is performed, when the detection unit detects that the supply operation of the yarn supply bobbin to the unwinding position is successful, the yarn supply bobbin to the display unit The supply alarm display is canceled.

  As a result, the yarn feeding bobbin supply alarm can be automatically canceled without operator intervention.

  In the yarn winding unit, the detection unit is preferably a sensor that detects a yarn layer in a yarn unwinding assisting device that assists in unwinding the yarn from the yarn supplying bobbin.

  As a result, the yarn winding bobbin supply success / failure can be detected by the sensor of the yarn unwinding assist device without providing a separate detection unit, so that the yarn winding unit can be easily configured and the cost can be reduced. Can be achieved.

  In the yarn winding unit, the detection unit may be configured to be a yarn detection sensor disposed on a yarn path between the package from the unwinding position.

  Also in this case, it is not necessary to separately provide a detection unit, and it is possible to reliably detect whether or not the yarn feeding bobbin has been supplied by detecting the yarn unwound from the yarn feeding bobbin.

  In the yarn winding unit, it is preferable that a standby time for waiting for the feeding operation of the conveyance guide can be set.

  Thereby, according to the supply capacity | capacitance of the yarn supply bobbin in the apparatus upstream of a yarn winding unit, the time which a conveyance guide waits without performing supply operation | movement can be set appropriately. Accordingly, after a yarn feeding bobbin supply error occurs, the conveying guide supplying operation can be resumed at an appropriate timing.

That is, the yarn winding device includes a plurality of the yarn winding units, a first tray conveyance path, and a plurality of second tray conveyance paths. The first tray conveyance path conveys the conveyance tray on which the yarn feeding bobbin is placed. The second tray conveyance path branches from the first tray conveyance path and is disposed in each of the plurality of yarn winding units. The conveyance guide supplies the conveyance tray of the second tray conveyance path to the unwinding position.

  As a result, the operator is notified when a yarn feeding bobbin supply error occurs in the yarn winding unit due to a delay in supply of the yarn feeding bobbin from the first tray conveying path, which is the main conveying path, to the second tray conveying path. Without having to do this, the feeding operation of the transport guide can be automatically performed again. Therefore, it can be expected that the yarn winding operation of the yarn winding unit automatically restarts.

  The yarn winding device preferably has the following configuration. That is, the yarn winding device includes a main control unit that can communicate with each of the control units of the plurality of yarn winding units. The plurality of yarn winding units are arranged side by side in the transport direction of the transport tray in the first tray transport path. Among the plurality of yarn winding units, a yarn feeding bobbin supply alarm is generated because the yarn feeding bobbin supplying operation to the unwinding position is not successful despite the conveyance guide performing the supplying operation. When there are two or more yarn winding units, the main control unit performs the feeding operation of the conveyance guide again in order from the yarn winding unit disposed upstream in the conveyance direction of the first tray conveyance path. The control unit performs the control to be performed.

  Accordingly, the supply operation of the transport guide can be efficiently performed in consideration of the high possibility that the yarn supplying bobbin is first supplied to the yarn winding unit located on the upstream side.

The main control unit includes a determination unit. The determination unit is configured to cause the yarn feeding bobbin supply alarm to be generated because the yarn feeding bobbin supplying operation to the unwinding position was not successful despite the feeding guide performing the feeding operation. Whether or not the yarn feeding bobbin supply alarm can be automatically canceled with respect to the take-up unit is determined based on whether the yarn feeding bobbin supply alarm is generated on the downstream side of the yarn winding unit. The determination is made based on the cancellation status of the yarn feeding bobbin supply alarm.

  Thereby, it can be determined whether the alarm of the yarn winding unit in which the yarn feeding bobbin supply alarm has occurred can be automatically eliminated. Therefore, when a relatively serious abnormality has occurred in the yarn winding unit, it is possible to notify the operator at an early stage.

  According to the third aspect of the present invention, the following yarn feeding bobbin supplying method is provided. That is, in this yarn supplying bobbin supplying method, the yarn supplying bobbin placed on the conveying tray is supplied to the unwinding position where the yarn is unwound by the conveying guide, and the yarn is fed from the yarn supplying bobbin at the unwinding position.

  The yarn supplying unit 3 includes a tray holding unit 27 disposed in the middle of the second bobbin conveyance path 72. As shown in FIG. 5, the tray holding unit 27 can hold the transport tray 13 on which the yarn supplying bobbin 11 is placed, and in this state, the yarn 12 can be unwound from the yarn supplying bobbin 11.

  As shown in FIG. 5, the tray holding unit 27 has a configuration in which the conveyance tray 13 is sandwiched and held by a tray contact unit 28 that contacts the conveyance tray 13 of the conveyance guide 26 and an elastic support unit 29. .

  The yarn supplying unit 3 is configured to hold the conveyance tray 13 on which the yarn supplying bobbin 11 is placed at the unwinding position by the tray holding unit 27 and unwind the yarn 12 from the yarn supplying bobbin 11 in this state. When the yarn 12 of the yarn supplying bobbin 11 disappears as the yarn 12 is unwound, the yarn supplying unit 3 discharges the transport tray 13 on which the empty yarn supplying bobbin 11 is placed from the unwinding position and newly supplies a new yarn. The conveyance tray 13 on which the bobbin 11 is placed is supplied to the unwinding position.

  Next, the discharge operation and supply operation of the yarn feeding bobbin 11 by the conveyance guide 26 will be briefly described.

  The control unit 30 appropriately controls the drive unit 31 to rotate the conveyance guide 26 clockwise from the state of FIG. 5 via the cam mechanism 32. As a result, as shown in FIG. 6, the transport tray 13 held by the tray holding unit 27 is opened, and the transport tray 13 is moved to the third bobbin transport path 73 by the pushing portion 26 b formed on the transport guide 26. Extrude towards At the same time, one conveyance tray 13 that has been blocked by the stopper portion 26 a of the conveyance guide 26 is introduced downstream in the conveyance direction by the rotation of the turntable 25.

  Subsequently, the control unit 30 controls the driving unit 31 to rotate the conveyance guide 26 counterclockwise from the state of FIG. 6 via the cam mechanism 32. As a result, the position of the conveyance guide 26 returns to the state shown in FIG. 5, so that the newly introduced conveyance tray 13 is held by the tray holding portion 27 and the conveyance tray 13 on the upstream side in the conveyance direction is blocked by the stopper portion 26 a. .

  As described above, the conveyance guide 26 performs the discharge (discharge operation) of the conveyance tray 13 and the introduction (supply operation) of the conveyance tray 13 by rotating the drive unit 31 controlled by the control unit 30. It is configured to perform reciprocal motions.

  In the winder unit 10 of the present embodiment, whether or not the yarn feeding bobbin 11 has been supplied to the unwinding position (whether or not the operation of supplying the yarn feeding bobbin 11 to the unwinding position has been successful) is determined. It is detected and specified using the above-described chase portion detection sensor 18. Specifically, the movable member 16 (chase portion detection sensor 18) is lowered to a sufficient position in advance, and the yarn feeding bobbin 11 that is blocked by the conveyance guide 26 in the second bobbin conveyance path 72 is unwound. When moving to the heel position, the tip of the yarn feeding bobbin 11 is configured to pass through the optical axis of the chase detection sensor 18. Thereby, the success or failure of the supply of the yarn supplying bobbin 11 by the conveyance guide 26 can be detected without separately providing a detection sensor for the yarn supplying bobbin 11.

  However, instead of detecting the success or failure of the supply of the yarn supplying bobbin 11 by the chase portion detection sensor 18, for example, a yarn detection sensor disposed between the unwinding auxiliary device 5 and the tension applying device 6 shown in FIG. 19 can also be detected. That is, since the yarn 12 cannot be unwound unless the yarn supplying bobbin 11 is supplied to the unwinding position, the yarn detection sensor 19 does not detect the yarn 12. By utilizing this fact, the yarn detection sensor 19 can be used for detecting the success or failure of the supply of the yarn supplying bobbin 11.

  The chase detection sensor 18 can also be used to adjust the position of the tip of the yarn feeding bobbin 11. That is, even if the transport tray 13 is held by the tray holding unit 27 at the above-described unwinding position, for example, when the yarn feeding bobbin 11 is obliquely set on the transport tray 13, the position of the tip of the yarn feeding bobbin 11 is set. However, the accuracy of the control of the balloon (the control of the tension of the yarn 12 to be unwound) is lowered. Therefore, when the yarn feeding bobbin 11 that has been blocked by the conveyance guide 26 is moved to the unwinding position by the supply operation of the conveyance guide 26, the yarn feeding bobbin 11 (tip portion) is detected by the chase portion detection sensor 18. Then, based on the detection timing, it is conceivable to obtain the positional deviation amount of the tip portion of the yarn feeding bobbin 11. In this case, in consideration of the obtained positional deviation amount, the position where the transport tray 13 is held by the tray holding portion 27 is adjusted (for example, by an appropriate actuator) to assist the unwinding of the tip end portion of the yarn feeding bobbin 11. The balloon can be suitably controlled by positioning with respect to the device 5 with high accuracy. Then, by using this chase portion detection sensor 18 to determine whether the supply of the yarn supplying bobbin 11 is successful, it is possible to appropriately determine the supply of the yarn supplying bobbin 11 at an early timing after the supply operation of the conveyance guide 26. Can do.

  The control unit 30 performs control for newly supplying the yarn feeding bobbin 11 to the unwinding position at the start of the yarn winding operation for forming the package 20 or after the yarn 12 is unwound from the yarn feeding bobbin 11. be able to. Moreover, the control part 30 can perform control which supplies the yarn feeding bobbin 11 to a unwinding position again, when the yarn feeding bobbin 11 cannot be supplied to a unwinding position also by said control. Details of these controls will be described later.

  Next, the electrical configuration of the winder unit 10 will be described with reference to FIG. FIG. 8 is a block diagram showing a control configuration of the automatic winder 100.

  As shown in FIGS. 3 and 8, the operation panel 34 includes a 7-segment display 36 with a three-digit display, an operation button unit 37 laid out in a cross shape, an operation switch 38, and an alarm lamp 39. Is provided.

  The 7-segment display 36 is configured to display 3-digit information stored in the RAM including at least one of letters, numbers, and symbols.

  The operation button unit 37 includes a left button 37a, a right button 37b, an upper button 37c, a middle button 37d, and a lower button 37e. Each button 37 a to 37 e is configured to detect an operation to be pressed and to send an electrical signal to the control unit 30. The upper button 37c, the middle button 37d, and the lower button 37e have built-in lamps, and the control unit 30 can control lighting and extinguishing of these lamps.

  The operation switch 38 is configured as a switch that can be toggled, and is connected to the control unit 30. By operating the operation switch 38, the operation of the winder unit main body 1 can be operated or stopped.

  As shown in FIG. 3, the alarm lamps 39 are arranged on the left and right sides of the operation button unit 37 and are configured to display the state of the winder unit 10. Examples of the state of the winder unit 10 indicated by the alarm lamp 39 include a state in which the package 20 is full, a state in which a defect has occurred in the yarn joining device 7, and the like. The lighting state of the alarm lamp 39 is controlled by the control unit 30.

  As shown in FIG. 8, the display unit 35 of the winder unit 10 of the present embodiment includes a lamp built in the upper button 37c, the middle button 37d, and the lower button 37e described above, a 7-segment display 36, an alarm, And a lamp 39.

  The control unit 30 is electrically connected to a drive unit 31 that drives the turntable 25 and the conveyance guide 26 of the yarn supplying unit 3. The control unit 30 can control the operation of the transport guide 26 by transmitting an appropriate signal to the drive unit 31. The control unit 30 is electrically connected to the machine base control device 91 of the automatic winder 100 and is configured to perform various controls in accordance with commands from the machine base control device 91.

  Next, control related to the supply operation of supplying the yarn supplying bobbin 11 to the unwinding position of the yarn 12 in the conveyance guide 26 of the winder unit 10 of the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing control related to the supply operation of the transport guide 26.

  The flow shown in FIG. 9 is started when the winder unit 10 starts the yarn winding operation for forming the package 20 or when the yarn 12 is removed from the yarn supplying bobbin 11 held at the unwinding position. . When this flow starts, the control unit 30 of the winder unit 10 first causes the transport guide 26 to be supplied (step S101).

  In the above description, it is expressed that “the supply operation is performed”, but in the present embodiment, as described above, both the discharge operation and the supply operation of the conveyance guide 26 are performed once for the conveyance guide 26. It is comprised so that it may implement | achieve by reciprocation. Accordingly, when the conveyance guide 26 performs the supply operation, the discharge operation is also performed. Therefore, when the yarn supplying bobbin 11 in which the yarn 12 is lost is held in the unwinding position, the yarn supplying bobbin 11 is unwound. Will be discharged from.

  After the conveyance guide 26 performs the supply operation according to the control of the control unit 30, the control unit 30 determines whether the yarn feeding bobbin 11 is supplied to the unwinding position based on the detection result of the chase unit detection sensor 18. (Step S102). When the yarn feeding bobbin 11 has been supplied to the unwinding position, the flow ends and the winding operation by the winder unit 10 is started. When the yarn feeding bobbin 11 is not supplied to the unwinding position, the control unit 30 immediately performs the supply operation of the transport guide 26 again (step S103).

  That is, when the yarn supplying bobbin 11 is not supplied to the unwinding position by the first supply operation, there is a possibility that the yarn supplying bobbin 11 is not waiting on the second bobbin conveying path 72 (stagnation on the upstream side). Of course, it is also possible that there is a high possibility that some slight catching has occurred in the transport tray 13 waiting in the second bobbin transport path 72. Therefore, it can be expected that the yarn feeding bobbin 11 can be quickly restored to a state where the yarn feeding bobbin 11 can be supplied by immediately repeating the feeding operation of the conveyance guide 26.

  After the conveyance guide 26 performs the supply operation again according to the control of the control unit 30, the control unit 30 determines whether the yarn feeding bobbin 11 is supplied to the unwinding position based on the detection result of the chase unit detection sensor 18. The determination is made again (step S104). When the yarn feeding bobbin 11 has been supplied to the unwinding position, the flow ends and the winding operation by the winder unit 10 is started. When the yarn feeding bobbin 11 is not supplied to the unwinding position, the control unit 30 displays a yarn feeding bobbin supply alarm on the display unit 35 (step S105).

  As an example of display of the yarn feeding bobbin supply alarm, the 7-segment display 36 of the display unit 35 displays alarm information including at least one of characters, numbers, and symbols corresponding to the yarn feeding bobbin supply alarm. And lighting the alarm lamp 39, but are not limited thereto. In addition, the control unit 30 displays the yarn feeding bobbin supply alarm on the display unit 35 as described above, notifies the machine control device 91 of the occurrence of the yarn supply bobbin supply alarm, and the liquid crystal of the machine control device 91. It can also be displayed on the monitor 92 or the like.

  After generating the yarn feeding bobbin supply alarm, the control unit 30 waits for a predetermined time (set time) without performing the supply operation of the transport guide 26 (steps S106 and S107). When the predetermined time has elapsed, the control unit 30 causes the conveyance guide 26 to be supplied again (step S108).

  That is, if the yarn feeding bobbin 11 is not supplied to the unwinding position even if the feeding operation of the conveying guide 26 is performed twice, one yarn feeding bobbin 11 is stuck in the second bobbin conveying path 72 (stuck on the upstream side). Most likely not waiting. Accordingly, in this case, the supply operation of the conveyance guide 26 is performed after waiting for a certain amount of time, thereby securing a time margin until the supply of the yarn feeding bobbin 11 that has been stagnated returns to the original state, and a wasteful supply operation. Can be reduced.

  Note that the automatic winder 100 of the present embodiment is configured so that the time to wait in steps S106 and S107 can be set via the input unit 93 of the machine base control device 91. Thereby, the operator can restart the supply operation of the conveyance guide 26 at a suitable timing by appropriately setting the standby time in consideration of the supply capability of the yarn supply bobbin supply device 101, for example.

  After the conveyance guide 26 performs the supply operation according to the control of the control unit 30, the control unit 30 determines whether the yarn feeding bobbin 11 is supplied to the unwinding position based on the detection result of the chase unit detection sensor 18. (Step S109). When the yarn feeding bobbin 11 has been supplied to the unwinding position, the control unit 30 cancels the display of the yarn feeding bobbin supply alarm on the display unit 35 (step S110). Thereafter, the flow ends and the winding operation by the winder unit 10 is started.

  When the yarn feeding bobbin 11 has not been supplied to the unwinding position, the number of times that the control unit 30 performs the control (the processing in steps S106 to S108) to be performed after the supply operation of the conveyance guide 26 is waited is predetermined. It is determined whether or not the limit number of times (maximum number of repetitions) has been reached (step S111). If the number of repetitions of the standby and supply operations has not reached the above limit number, the process returns to step S106. When the above number of times reaches the predetermined limit number, it is determined that the possibility of succeeding in supplying the yarn feeding bobbin 11 is low even if the supplying operation is repeated further, and a notification requesting the operator's work is performed. (Step S112), and the flow ends.

  That is, if the supply error is not eliminated even if the supply operation of the yarn supplying bobbin 11 is repeated a sufficient number of times, a relatively serious abnormality has occurred, and the possibility of success is low even if the supply operation is repeated further. it is conceivable that. Therefore, in the present embodiment, in the above case, the abandonment of automatically canceling the alarm is abandoned and the recovery is entrusted to the operator.

  In the winder unit 10 of the present embodiment, the machine controller 91 also determines how many times the supply operation (steps S106 to S108) after waiting for a predetermined time should be repeated, that is, the above-mentioned limit number of times in step S111. It can be set via the input unit 93. Thus, the operator can appropriately set the above limit number of times in consideration of, for example, the number of winder units 10 in which one person is in charge of maintenance work.

  In the present embodiment, the notification to the operator in step S112 is performed by lighting a lamp built in the lower button 37e of the operation button unit 37. However, the present invention is not limited to this. For example, a lamp built in the lower button 37e is turned on, and an appropriate alarm generation signal is transmitted to the machine base control device 91 to be displayed on the liquid crystal monitor 92 of the machine base control device 91. May be.

  The operator who notices that the lamp of the lower button 37e is lit confirms, for example, whether the second bobbin conveyance path 72 is clogged, and causes the yarn supplying bobbin 11 to be normally supplied to the winder unit 10. Perform work as appropriate. When the operator wants to quickly resume the yarn winding operation by the winder unit 10, the operator manually operates the conveyance tray 13 with the yarn feeding bobbin 11 placed on the second bobbin conveyance path 72 (upstream from the conveyance guide 26). It can also be set with. After the above work is completed, the operator performs an operation of pressing the lower button 37e whose lamp is lit (operation for notifying the completion of the work). The control unit 30 that has detected that the lower button 37e is pressed turns off the lamp of the lower button 37e and starts the flow of FIG. 9 from the beginning. As a result, the supply operation of the yarn feeding bobbin 11 by the conveyance guide 26 is performed again.

  By configuring as described above, the control unit 30 can perform three controls (first supply control, second supply control, and third supply control) regarding the supply of the yarn feeding bobbin 11. In the first supply control, a supply operation of the conveyance guide 26 is performed in order to newly supply the yarn supply bobbin 11 to the unwinding position (step S101). In the second supply control, after the supply of the yarn supplying bobbin 11 fails in the first supply control, the supply operation of the transport guide 26 is performed again without taking a long time (step S103). In the third supply control, when the supply of the yarn feeding bobbin 11 fails even in the second supply control, the supply operation of the conveyance guide 26 is waited for a predetermined time, and then the supply operation of the conveyance guide 26 is performed again (step). S106 to S108). When the supply of the yarn feeding bobbin 11 fails in the second supply control, the yarn supply bobbin supply alarm displayed on the display unit 35 disappears when the supply of the yarn supply bobbin 11 is successful in the third supply control. .

  That is, the winder unit 10 according to the present embodiment has a yarn feeding bobbin that fails to supply the yarn feeding bobbin 11 for some reason even when the feeding operation of the conveyance guide 26 is performed twice (that is, when a feeding error occurs). Although a supply alarm is generated, the supply of the yarn feeding bobbin 11 is retried by repeating the supply operation of the conveyance guide 26 a predetermined number of times thereafter. When the retry is successful, the alarm is automatically canceled, but when the supply fails even after a predetermined number of retries, the operator is notified for the first time (requesting the work by the operator) and stopped. .

  As a result, for example, when a supply error occurs due to a delay in the supply of the yarn feeding bobbin 11 from the first bobbin conveyance path 71 to the second bobbin conveyance path 72, the supply operation of the conveyance guide 26 is performed again. Thus, it can be expected that the yarn winding operation of the winder unit 10 is automatically resumed (without operator intervention) when the supply of the yarn feeding bobbin 11 is recovered.

  Then, the supply operation of the conveyance guide 26 is intermittently performed at the time of the above retry (that is, after waiting for a predetermined time and then restarted), a certain time margin until the supply of the yarn feeding bobbin 11 is recovered is secured to some extent. be able to. Accordingly, it is possible to reduce the wasteful supply operation of the transport guide 26 and improve the success rate of the retry.

  Further, if the supply of the yarn feeding bobbin 11 fails even if the supply operation of the conveyance guide 26 is performed a predetermined number of times, the winder unit 10 notifies the operator and performs no further supply operation. Stop. Thereby, useless supply operation of the conveyance guide 26 can be prevented.

  As described above, the winder unit 10 of the present embodiment unwinds the yarn from the yarn supplying bobbin 11 placed on the transport tray 13 and forms the package 20. The winder unit 10 includes a conveyance guide 26, a control unit 30, and a chase unit detection sensor 18. The conveyance guide 26 performs a supply operation of supplying the yarn feeding bobbin 11 to a unwinding position where the yarn 12 is unwound. The control unit 30 controls the operation of the transport guide 26. The chase portion detection sensor 18 detects success or failure of the yarn feeding bobbin 11 supply operation by the conveyance guide 26. The control unit 30 performs conveyance when the chase unit detection sensor 18 detects that the supply operation of the yarn feeding bobbin 11 to the unwinding position has not been successful after the conveyance guide 26 performs the supply operation. The supply operation of the guide 26 is waited for a predetermined time, and then the supply operation of the conveyance guide 26 is performed again.

  Moreover, in the winder unit 10 of this embodiment, the yarn feeding bobbin 11 is supplied by a method including a supply operation process, a standby process, and a resupply operation process. In the supply operation process, the supply guide 26 is supplied with the supply guide bobbin 11 to the unwinding position (steps S101 / S103). In the standby process, when it is detected that the supply operation of the yarn feeding bobbin 11 to the unwinding position is not successful after the supply operation process, the supply operation of the transport guide 26 is waited for a predetermined time (step) S106, S107). In the resupply operation step, the supply operation is performed again by the transport guide 26 after the standby step (step S108).

  Thereby, when the supply mistake of the yarn feeding bobbin 11 occurs, the supply operation of the yarn feeding bobbin 11 in the conveyance guide 26 can be automatically retried without intervention of the operator. As a result, significant labor saving is possible. In addition, since the yarn feeding bobbin 11 can be expected to be newly conveyed to a position where the conveyance guide 26 can be supplied to the unwinding position while the conveyance guide 26 is waiting without performing the supply operation, A useless supply operation of the transport guide 26 can be avoided.

  Moreover, in the winder unit 10 of this embodiment, the control part 30 performs 1st supply control, 2nd supply control, and 3rd supply control. In the first supply control, in order to newly supply the yarn feeding bobbin 11 to the unwinding position at the start of the yarn winding operation for forming the package 20 or after the yarn 12 is unwound from the yarn feeding bobbin 11. The supply operation of the transport guide 26 is performed (step S101). In the second supply control, immediately after the first supply control is performed, immediately after the supply operation of the yarn feeding bobbin 11 to the unwinding position is determined by the detection of the chase portion detection sensor 18, The supply operation of the guide 26 is performed again (step S103). In the third supply control, when the supply operation of the yarn feeding bobbin 11 to the unwinding position is not succeeded after the second supply control is performed, the conveyance guide is specified. The supply operation of 26 is waited for a predetermined time, and then the supply operation of the transport guide 26 is performed again (steps S106 to S108).

  Thereby, after the supply mistake of the yarn supplying bobbin 11 occurs, the supply operation is immediately repeated at first, thereby eliminating, for example, slight catching of the yarn supplying bobbin, and quickly entering a state where the yarn supplying bobbin can be supplied. Can be expected to recover. If the yarn supplying bobbin 11 is not supplied even if the supplying operation is immediately performed again, there is a high possibility that the supply of the yarn supplying bobbin from the upstream side is stagnant. By performing the supply operation again, useless supply operation can be prevented. As described above, when a supply mistake of the yarn feeding bobbin 11 occurs, the supply operation of the conveyance guide 26 is repeated at a reasonable timing, thereby efficiently returning the yarn feeding bobbin 11 from the state where the yarn feeding bobbin 11 is not supplied to the unwinding position. be able to.

  Further, the winder unit 10 of the present embodiment is configured to be able to set the maximum number of repetitions of the third supply control performed after the second supply control is performed (the limited number of times used in the determination in step S111). Yes.

  As a result, when the yarn feeding bobbin 11 is not supplied to the unwinding position even after the third supply control is performed a predetermined number of times (that is, the yarn feeding bobbin 11 is successfully supplied even if the supply operation is repeated further. When the supply operation is not performed), the useless supply operation of the transport guide 26 can be prevented. In addition, since the number of times of repeating the supply operation can be flexibly set according to various situations, convenience can be improved.

  Further, in the winder unit 10 of the present embodiment, the control unit 30 detects that the feeding operation of the yarn feeding bobbin to the unwinding position has not succeeded after the third supply control has been performed the maximum number of times. When specified by the detection of the sensor 18, the operator's work is requested (notification to the operator is performed).

  As a result, when the supply mistake of the yarn feeding bobbin 11 occurs, the operation of supplying the transport guide 26 in the winder unit 10 is automatically performed again, and the operator's work is performed when the supply fails even if it is performed a predetermined number of times. Since the configuration is required, frequent calls to the operator can be avoided and the efficiency of the entire winder unit 10 can be increased.

  Further, the winder unit 10 of the present embodiment includes a display unit 35. The display unit 35 displays, as a yarn feeding bobbin supply alarm, that the feeding operation of the yarn feeding bobbin 11 to the unwinding position was not successful after the second supply control was performed (step S105). After the third supply control is performed, when it is determined by the detection of the chase part detection sensor 18 that the supply operation of the yarn supply bobbin 11 to the unwinding position is successful, the yarn supply bobbin supply to the display unit 35 is performed. The alarm display is canceled (step S110).

  As a result, the yarn feeding bobbin supply alarm can be automatically canceled without operator intervention.

  In the winder unit 10 of the present embodiment, the chase detection sensor 18 that detects the yarn layer in the unwinding assisting device 5 that assists the unwinding of the yarn from the yarn supplying bobbin 11 includes the yarn supplying bobbin by the conveyance guide 26. 11 supply success or failure is detected.

  Thereby, since it is not necessary to provide a detection part specially, while the winder unit 10 can be comprised simply, cost reduction can be aimed at.

  However, the success or failure of the supply of the yarn supplying bobbin 11 by the conveyance guide 26 can also be detected by the yarn detection sensor 19 disposed on the yarn path between the unwinding position and the package 20.

  Also in this case, since it is not necessary to provide a detection unit specially, the winder unit 10 can be simply configured and the cost can be reduced.

  Further, the winder unit 10 of the present embodiment is configured such that a standby time for waiting for the feeding operation of the conveyance guide 26 can be set.

  Thereby, according to the supply capability of the yarn supply bobbin 11 in the yarn supply bobbin supply device 101, it is possible to appropriately set the time for which the conveyance guide 26 waits without performing the supply operation. Therefore, after the supply mistake of the yarn feeding bobbin 11 occurs, the supply operation of the conveyance guide 26 can be restarted at an appropriate timing.

  The automatic winder 100 according to the present embodiment includes a plurality of winder units 10, a first bobbin transport path 71, and a plurality of second bobbin transport paths 72. The first bobbin conveyance path 71 is for conveying the conveyance tray 13 on which the yarn supplying bobbin 11 is placed. The second bobbin conveyance path 72 branches from the first bobbin conveyance path 71 and is disposed in each of the plurality of winder units 10. The conveyance guide 26 supplies the conveyance tray 13 of the second bobbin conveyance path 72 to the unwinding position.

  Accordingly, when the supply bobbin 11 is mistakenly supplied to the winder unit 10 due to the supply of the yarn supply bobbin 11 from the first bobbin transfer path 71 as the main transfer path to the second bobbin transfer path 72 being delayed. The feeding operation of the conveyance guide 26 can be automatically performed again without requiring notification to the operator. Therefore, it can be expected that the yarn winding operation of the winder unit 10 automatically restarts.

  Next, a modified example in which a plurality of winder units 10 perform a supply operation in cooperation will be described with reference to FIG.

  That is, in the winder unit 10 of the above embodiment, the supply operation of the transport guide 26 is independently controlled regardless of the state of the other winder units 10. On the other hand, in this modification, the machine controller 91 that controls the plurality of winder units 10 performs the control shown in FIG. 10 to control the feeding operation of the conveyance guides 26 of the respective winder units 10. .

  This will be specifically described below. When the flowchart shown in FIG. 10 starts, the machine base control device 91 first waits until a yarn feeding bobbin supply alarm is generated in any of the winder units 10 (step S201). In the following description, the winder unit 10 in which the yarn feeding bobbin supply alarm is generated (except for those that have reached the stage of notifying the operator) may be referred to as an alarm generating unit.

  If any of the winder units 10 has a yarn feeding bobbin supply alarm, the machine control device 91 checks whether a plurality of winder units 10 have a yarn feeding bobbin supply alarm (step S202). If there is only one alarm generating unit, the machine control device 91 causes the alarm generating unit to perform the operation (supply operation after waiting for a predetermined time) shown in steps S106 to S111 in FIG. 9 (step S203). ). Thereafter, the process returns to step S201.

  If it is determined in step S202 that there are two or more alarm generation units, the machine base control device 91 determines that only the alarm generation unit located on the most upstream side in the transfer direction of the first bobbin transfer path 71 is predetermined. Control is performed so as to repeatedly perform the supply operation after waiting for a time (step S204), and the other alarm generation units are controlled to simply wait without performing the supply operation (step S205). Thereafter, the process returns to step S201.

  When the machine control device 91 performs the above-described control and a yarn feeding bobbin supply alarm is generated in the plurality of winder units 10 of the automatic winder 100, the supply operation of the yarn feeding bobbins 11 in the plurality of winder units 10 is performed. The restart can be rationally performed according to the position of the winder unit 10. This is because, as described above, the first bobbin conveyance path 71 of the present embodiment is arranged on the upstream side in order to supply the yarn feeding bobbin 11 in order from the winder unit 10 located on the most upstream side in the conveyance direction. This is because the yarn feeding bobbin 11 is likely to be supplied to the winder unit 10 first.

  As described above, the automatic winder 100 according to the present embodiment includes the machine control device 91 that can communicate with each of the control units 30 of the plurality of winder units 10. The plurality of winder units 10 are arranged side by side in the transport direction of the transport tray 13 in the first bobbin transport path 71. Among the plurality of winder units 10, the winder in which the yarn feeding bobbin supply alarm is generated because the feeding operation of the yarn feeding bobbin 11 to the unwinding position is not successful despite the feeding guide 26 performing the feeding operation. When there are two or more units 10, the machine base control device 91 controls the control to cause the supply operation of the conveyance guide 26 to be performed again in order from the winder unit 10 arranged on the upstream side with respect to the first bobbin conveyance path 71. Let the unit 30 do this.

  Thereby, considering that there is a high possibility that the yarn supplying bobbin 11 is supplied to the winder unit 10 located on the upstream side, the supply operation of the transport guide 26 can be performed efficiently.

  Next, another modification example related to the control performed by the machine base control device 91 will be described.

  That is, in the above modification (FIG. 10), when there are a plurality of alarm generating units, the machine control device 91 sequentially starts from the alarm generating unit on the most upstream side in the transfer direction of the first bobbin transfer path 71 for a predetermined time. Control is performed so that the supply operation after waiting is performed.

  In this regard, in this modification, even if there are a plurality of alarm generation units, each alarm generation unit independently performs a supply operation after waiting for a predetermined time (in other words, the machine control device 91 is The order of the alarm generating units that perform the supply operation is not particularly controlled). Therefore, in this modification, two or more alarm generation units simultaneously perform the supply operation after waiting for a predetermined time.

  The machine base control device 91 monitors the state of the yarn feeding bobbin supply alarm for each alarm generation unit. If the yarn feeding bobbin supply alarm of the alarm generating unit downstream of the first bobbin transport path 71 in the transport direction among the plurality of alarm generating units is canceled first, the alarm generating unit on the upstream side thereof With respect to, it is considered that there is a high possibility that a relatively serious abnormality (that is, an abnormality that cannot be automatically restored) such as clogging of the second bobbin conveyance path 72 has occurred. This is because the yarn supplying bobbin 11 is sequentially supplied from the upstream winder unit 10, and if the supply of the yarn supplying bobbin 11 is merely insufficient, the upstream alarm generating unit is accompanied by the solution of the shortage. This is because the yarn feeding bobbin supply alarm should be canceled.

  In this regard, the machine base control device 91 of this modification includes a determination unit (not shown), and this determination unit determines whether or not the alarm generation unit can automatically cancel the yarn feeding bobbin supply alarm. It is configured to be possible. Specifically, when the yarn feeding bobbin supply alarm is canceled first for the downstream alarm generating unit among the plurality of alarm generating units, this determination unit determines the upstream alarm generating unit. Determines that the yarn feeding bobbin supply alarm cannot be cleared automatically. If the determination unit determines that the alarm cannot be automatically cleared, the machine control device 91 causes the alarm generation unit to wait while the supply operation after waiting for a predetermined time does not reach the above limit number. Control is performed so that notification for requesting the operator's work is immediately performed. According to this control, it is possible to prevent a wasteful supply operation of the conveyance guide 26 for the winder unit 10 that cannot be expected to eliminate the yarn feeding bobbin supply alarm.

  As described above, in the automatic winder 100 of the present modification, the yarn feeding bobbin 11 is arranged in order from the winder unit 10 disposed upstream in the transport direction of the first bobbin transport path 71 in the second winder unit 10. It is supplied to the bobbin conveyance path 72. The machine base control device 91 includes a determination unit. The determination unit applies to the winder unit 10 in which the yarn feeding bobbin supply alarm is generated because the feeding operation of the yarn feeding bobbin 11 to the unwinding position is not successful even though the feeding guide 26 performs the feeding operation. Thus, whether or not the yarn feeding bobbin supply alarm can be automatically canceled is determined based on the yarn feeding bobbin supply alarm in the winder unit 10 in which the yarn feeding bobbin supply alarm is generated downstream of the winder unit 10. Judgment is based on the resolution status.

  Thereby, it can be determined whether the alarm of the winder unit 10 in which the yarn feeding bobbin supply alarm has occurred can be automatically eliminated. Therefore, when a relatively serious abnormality occurs in the winder unit 10, it is possible to notify the operator at an early stage.

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

  The processes shown in the flowcharts of FIGS. 9 and 10 are examples, and the order of some processes may be changed or deleted, two processes may be performed simultaneously, or other processes may be added.

  The automatic winder 100 of the above embodiment is configured separately from the yarn supplying bobbin supplying device 101, but is not limited thereto, and may be configured integrally with the yarn supplying bobbin supplying device 101.

  When a supply error of the yarn supplying bobbin 11 occurs in a certain winder unit 10, the supply error is displayed on the display unit 35 of the winder unit 10 as a yarn supplying bobbin supply alarm. However, the present invention is not limited to this. The yarn feeding bobbin supply alarm may be displayed on both the display unit 35 and the machine base control device 91 of the winder unit 10.

  Instead of the chase part detection sensor 18 or the like, for example, by providing a pressure sensor or the like in the stopper part 26a of the conveyance guide 26, the success or failure of the supply of the yarn supplying bobbin 11 can be detected. It is also possible to provide a detection sensor for directly detecting the yarn feeding bobbin 11 at the unwinding position.

  In the above-described embodiment, the conveyance guide 26 is configured to perform both the supply operation and the discharge operation. However, the supply guide and the discharge operation may be configured to be performed by separate members.

  In the above-described embodiment, the yarn feeding bobbin 11 is sequentially supplied downstream from the winder unit 10 located on the most upstream side in the conveying direction of the first bobbin conveying path 71. That is, until the number of yarn feeding bobbins 11 waiting in the most upstream winder unit 10 reaches the upper limit (three) as shown in FIG. The yarn feeding bobbin 11 is supplied to the winder unit 10 on the downstream side one time only after the upper limit is reached. However, the present invention is not limited to this, and the yarn feeding bobbin 11 may be supplied to the winder unit 10 on the downstream side before the number of waiting yarn feeding bobbins 11 in a certain winder unit 10 reaches the upper limit.
