Description

  More specifically, the present invention relates to a technology for discharging a bobbin for yarn feeding held in an automatic winder.

  Conventionally, an automatic winder is provided with a plurality of winding units, and a conveyer is provided along the plurality of winding units. The bobbin supplied to the winding unit is discharged from the winding unit after being wound. At this time, the bobbin is discharged to a fixed discharge position by the bobbin holding device (for example, Patent Document 1). And the bobbin discharged | emitted from a winding unit is conveyed to an apparatus edge part by a conveyance conveyor, and is put in an empty bobbin box.

However, the bobbin discharged from the winding unit is not only an empty bobbin in which all of the wound yarn has been unwound, but also satisfies a predetermined quality that is difficult to wind due to frequent yarn breakage. A bobbin with a residual thread that is not defective, or a bobbin with a residual thread that cannot be processed due to yarn breakage during spinning or a malfunction of the apparatus may be discharged. Accordingly, the bobbin discharged from the winding unit is conveyed by the conveyor while the empty bobbin and the bobbin with remaining yarn are mixed. For this reason, the operator sorts and collects the empty bobbin and the bobbin with remaining yarn on the machine end side of the automatic winder.

When the second lever 84 is pulled, the connection portion 83 of the second probe 81 rotates counterclockwise as shown in FIG. As the connecting portion 83 rotates counterclockwise in FIG. 3, the discharge plate portion 82 of the second probe 81 rotates counterclockwise in FIG. At this time, as shown in FIG. 8, the discharge plate portion 82 comes into contact with the bottom surface of the core tube 7 a of the bobbin 7 and pushes the bobbin 7 to the rear side of the winding unit 1. Further, as shown in FIG. 9, the discharge plate portion 82 has a recess made up of an inner wall of the first long side portion 82a, an inner wall of the second long side portion 82b, and an inner wall of the short side portion 83c. When the discharge plate portion 82 pushes out the bobbin 7 to the rear side of the winding unit 1, the peg 21 and the cricket 22 pass through the recess, so that the second probe 81 comes into contact with the peg 21 and the cricket 22. There is no.

  Next, the 1st bobbin conveyance part 2 and the 2nd bobbin conveyance part 3 are demonstrated. FIG. 10 is a side view of the first bobbin transport unit 2 and the second bobbin transport unit 3. The first bobbin transport unit 2 has a first conveyor 3 </ b> A at a first bobbin discharge position 95 on the front side of the winding unit 1. The first conveyor 3A conveys the bobbin 7 discharged to the first bobbin discharge position 95 to the bobbin collection unit 4 (FIG. 1). Specifically, as shown in FIG. 10, the first conveyor 3 </ b> A removes the bobbin 7 discharged from the one direction of the arrow 9 of the winding unit 1 to the first bobbin discharge position 95 by the first conveyor 3 </ b> A in FIG. 10. Transport from the front of the paper toward the back of the paper.

  The second bobbin transport unit 3 includes a second conveyor 3B at the second bobbin discharge position 96 on the rear side of the winding unit 1. The second conveyor 3B conveys the bobbin 7 discharged to the second bobbin discharge position 96 to the bobbin collecting unit 4 (FIG. 1). Specifically, as shown in FIG. 10, the second conveyor 3B is configured to transfer the bobbin 7 discharged from the direction of the arrow 92 of the winding unit 1 to the second bobbin discharge position 96 by the second conveyor 3B. Transport from the front toward the back of the page.

  Thus, the 1st bobbin conveyance part 2 and the 2nd bobbin conveyance part 3 convey the bobbin 7 discharged | emitted before and behind the winding unit 1 with a separate conveyor (1st conveyor 3A, 2nd conveyor 3B). Therefore, the bobbin 7 can be sorted and conveyed according to the state of the bobbin 7 (presence / absence of yarn, quality, etc.).

  Next, the circuit configuration of the winding unit 1 will be described. FIG. 11 is a block diagram showing a circuit configuration of the winding unit 1. Each device is connected to the winding unit 1 around the control unit 90. The control unit 90 receives a signal transmitted from each device and controls other devices according to the signal.

  As shown in FIG. 11, the yarn detection device 14 is connected to the control unit 90. When the yarn detection device 14 detects the chase portion 7 b of the bobbin 7, the yarn detection device 14 transmits a detection signal to the control unit 90. When the control unit 90 does not receive the detection signal from the yarn detection device 14, the control unit 90 lowers the balloon controller 10 and tries to detect the chase unit 7b. At this time, the control unit 90 determines that the bobbin 7 is empty when the chase unit 7b is not detected even when the balloon controller 10 is moved to the lowest point and no detection signal is received from the yarn detection device 14. To do. When determining that the bobbin 7 is empty, the control unit 90 transmits an empty bobbin discharge signal to each device including the bobbin holding device 70.

  As shown in FIG. 11, the yarn clearer 13 is connected to the control unit 90. The yarn clearer 13 detects whether or not the yarn 8 is running, and at the same time, detects the thickness of the yarn 8. The yarn clearer 13 detects a defect of the yarn 8 when the thickness of the yarn 8 is out of the allowable range, and transmits a defect detection signal to the control unit 90. When receiving the defect detection signal from the yarn clearer 13, the controller 90 determines that there is a defective portion in the yarn 8 that has passed through the yarn clearer 13. When the yarn clearer 13 detects a defective portion of the yarn 8, the winding unit 1 stops the winding operation and removes the defective portion of the yarn 8. Specifically, when the yarn clearer 13 detects a defective portion of the yarn 8, the winding unit 1 immediately cuts the yarn 8 and stops the driving of the package 9. At this time, the yarn end of the upper yarn, which is the cut yarn 9 on the package 9 side, is wound around the package 9 that rotates inertially in a state including the defective portion. Next, the winding unit 1 sucks the upper thread with the suction mouse 41 while rotating the package 9 in the direction opposite to the winding direction. At this time, the defective portion of the yarn 8 wound around the package 9 is also sucked into the suction mouse 41. Thereafter, the suction mouse 41 guides the upper thread to the yarn joining device 40 and joins the lower thread with the lower thread. At that time, the yarn end of the upper yarn including the defective portion of the yarn 8 is cut by the yarn joining device 40 and sucked and removed by the suction mouse 41.

  Although the defective portion of the yarn 8 is removed as described above, if the removal of such a defective portion is frequently repeated, the working efficiency of the winding unit 1 is lowered. Therefore, it is preferable in terms of work efficiency that the bobbin 7 whose defective portion is frequently detected by the yarn clearer 13 is discharged as a bobbin with defective remaining yarn. Therefore, when the frequency of detecting the defective portion by the yarn clearer 13 exceeds a predetermined frequency, the control unit 90 transmits a bobbin discharge signal with a defective remaining yarn to each device including the bobbin holding device 70. Here, the predetermined frequency can be arbitrarily determined by the operator, and can be determined in consideration of work efficiency.

Next, the operation when the bobbin 7 is discharged to the first bobbin discharge position 95 on the front side of the winding unit 1 will be described.
As shown in FIG. 11, for example, when the control unit 90 does not receive the detection signal from the yarn detection device 14 even when the balloon controller 10 is lowered to the lowest point (the yarn detection device 14 is in the bobbin 7). When the chase unit 7 b is not detected), the control unit 90 transmits an empty bobbin discharge signal to the bobbin holding device 70.

  When the bobbin holding device 70 receives the empty bobbin discharge signal from the control unit 90, the bobbin holding device 70 operates the motor 77 in the clockwise direction of FIG. By operating the motor 77, the rotation shaft 23 rotates in the clockwise direction shown in FIG. By rotating the rotation shaft 23, the peg 21 of the bobbin holding portion 20 rotates to a holding position (the above-mentioned first holding position) where the bobbin 7 shown in FIG. 7 can be discharged to the first bobbin discharging position 95. And then stop. At this time, the cricket 22 is interlocked with the peg 21 so that the bobbin 7 is maintained. At the same time, the bobbin holding device 70 operates the actuator 24 to rotate the cricket 22 toward the peg 21 side. As a result, the peg 21 and the cricket 22 are closed, and the holding of the bobbin 7 is released. At the same time, the lower part of the bobbin chute 60 is opened so that the bobbin 7 in the bobbin holding device 70 can be discharged to the first bobbin discharge position 95.

  On the other hand, the bobbin holding device 70 operates the motor 77 to rotate the rotation shaft 23, whereby the first probe 71 of the bobbin discharge portion 25 stopped at the position toward the center of the winding unit 1. The discharge plate portion 72 rotates toward the front of the winding unit 1 (clockwise in FIG. 3). At this time, as shown in FIG. 7, the discharge plate portion 72 contacts the bottom surface of the core tube 7 a of the bobbin 7 and pushes the bobbin 7 toward the front side of the winding unit 1. As described above, the bobbin holding device 70 operates the bobbin holding unit 20 and the bobbin discharge unit 25, whereby the bobbin 7 is discharged from the front side of the winding unit 1 to the first bobbin discharge position 95.

Next, an operation when the bobbin 7 is discharged to the second bobbin discharge position 96 on the rear side of the winding unit 1 will be described.
As shown in FIG. 11, for example, the control unit 90 receives a detection signal from the yarn detection device 14 (when the yarn detection device 14 detects the chase portion 7 b of the bobbin 7), and the yarn clearer 13 detects the yarn 8. When the detection frequency of the defective portion exceeds a predetermined frequency (when the control unit 90 determines that the quality of the yarn 8 wound around the bobbin 7 is poor), the control unit 90 determines that the bobbin currently being wound is A bobbin discharge signal with a defective remaining yarn that is a bobbin with defective remaining yarn in which many defective portions are mixed is transmitted to the bobbin holding device 70.

  When the bobbin holding device 70 receives the bobbin discharge signal with defective remaining yarn from the control unit 90, the bobbin holding device 70 operates the motor 77 counterclockwise in FIG. By operating the motor 77, the rotation shaft 23 rotates counterclockwise as shown in FIG. By rotating the rotation shaft 23, the peg 21 of the bobbin holding portion 20 rotates to a holding position (the above-described second holding position) where the bobbin 7 shown in FIG. 8 can be discharged to the second bobbin discharging position 96. And then stop. At this time, the cricket 22 is interlocked with the peg 21 so that the bobbin 7 is maintained. Thereafter, the bobbin holding device 70 operates the actuator 24 to rotate the cricket 22 toward the peg 21 side. As a result, the peg 21 and the cricket 22 are closed, and the holding of the bobbin 7 is released.

  On the other hand, the bobbin holding device 70 operates the motor 77 to rotate the rotating shaft 23, so that the second probe 81 of the bobbin discharging unit 25 stopped at the position toward the center of the winding unit 1. The discharge plate portion 82 rotates toward the rear of the winding unit 1 (counterclockwise in FIG. 3). At this time, as shown in FIG. 8, the discharge plate portion 82 comes into contact with the bottom surface of the core tube 7 a of the bobbin 7 and pushes the bobbin 7 to the rear side of the winding unit 1. As described above, when the bobbin holding device 70 operates the bobbin holding unit 20 and the bobbin discharging unit 25, the bobbin 7 is discharged from the rear side of the winding unit 1 to the second bobbin discharging position 96.

  Thus, the winding unit 1 can change the discharge direction of the bobbin 7 by rotating the motor 77 of the bobbin holding device 70 forward or reverse. Accordingly, the winding unit 1 controls the bobbin holding device 70 in accordance with the state of the yarn 8 wound around the bobbin 7 (presence / absence of yarn, quality, etc.), so that the discharging direction of the bobbin 7 matches the state of the bobbin 7. Can be distributed. Hereinafter, a method for distributing the bobbins 7 when the bobbins 7 are discharged from the winding unit 1 will be described. Note that the present invention is not limited to the following distribution method.

  First, the case where the discharge direction of the bobbin 7 is selected based on the presence or absence of the yarn wound around the bobbin 7 will be described. FIG. 12 is a flowchart in the case where the discharge direction of the bobbin 7 is selected based on the presence / absence of the yarn 8 wound around the bobbin 7.

  The automatic winder 100 uses, for example, a bobbin with remaining yarn (a bobbin with a take-up remaining yarn and a bobbin with a defective remaining yarn), a first bobbin discharge position on the front side of the winding unit 1 according to a control program preset by an operator. Each discharge direction is selected so that the empty bobbin is discharged to the second bobbin discharge position 96 on the rear side of the winding unit 1. Hereinafter, the bobbin with remaining yarn (bobbin with take-up remaining yarn and bobbin with defective remaining yarn) is moved to the first bobbin discharge position 95 on the front side of the winding unit 1, and the empty bobbin is moved to the first side on the rear side of the winding unit 1. The case of discharging to the 2-bobbin discharge position 96 will be described.

  When the winding unit 1 starts the winding operation (S1), the yarn clearer 13 detects the presence or absence of a defective portion of the yarn 8 (S2). When the yarn clearer 13 detects a defective portion of the yarn 8 (S2-Yes), the yarn clearer 13 transmits a defect detection signal to the control unit 90. The controller 90 determines whether or not the defect detection signal transmitted from the yarn clearer 13 is generated at a predetermined frequency (S3). When the defect detection signal is not generated with a predetermined frequency (S3-No), the winding unit 1 continues the winding operation (S1). Here, the predetermined frequency is a frequency set in consideration of the yarn quality desired by the operator or work efficiency, and can be freely set and changed by the operator by changing the yarn type or the like.

  When the yarn clearer 13 detects a defective portion of the yarn 8 (S2-Yes) and the defect detection signal is generated at a predetermined frequency (S3-Yes), the control unit 90 outputs a bobbin discharge signal with a defective remaining yarn. It transmits to the winding unit 1 (S4), and controls to discharge the bobbin with defective remaining yarn from the front side of the winding unit 1 (S5). The bobbin holding device 70 of the winding unit 1 receives the bobbin discharge signal with the defective remaining yarn and receives the bobbin discharge signal to the first bobbin discharge position 95 as shown in FIG. The bobbin holding part 20 is rotated to the first holding position), and the first probe 71 of the bobbin discharging part 25 is operated to the front side of the winding unit 1. Thereby, the bobbin with defective remaining yarn is discharged to the first bobbin discharge position 95 (S6).

  When the yarn clearer 13 does not detect a defective portion of the yarn 8 (S2-No), the yarn detection device 14 detects the chase portion 7b of the bobbin 7 (S7). When the yarn detection device 14 detects the chase portion 7b of the bobbin 7 (S7-Yes), the control unit 90 determines whether the winding operation can be continued by tying the yarn (S8). When it is determined that the winding operation can be continued (S8-Yes), the winding unit 1 continues the winding operation (S1).

  When it is determined that the winding operation cannot be continued (S8-No), the control unit 90 transmits a bobbin discharge signal with a take-up remaining yarn to the winding unit 1 (S9), and the front side of the winding unit 1 To control the discharge of the bobbin with the remaining yarn that can be wound (S5). The bobbin holding device 70 of the winding unit 1 receives the bobbin discharge signal with the take-up remaining yarn, and as shown in FIG. 7, the bobbin 7 can be discharged to the first bobbin discharge position 95 (described above). The bobbin holding portion 20 is rotated to the first holding position), and the first probe 71 of the bobbin discharge portion 25 is operated to the front side of the winding unit 1. As a result, the bobbin with take-up remaining yarn is discharged to the first bobbin discharge position 95 (S6).

  When the yarn clearer 13 does not detect the defective portion of the yarn 8 (S2-No) and the yarn detection device 14 does not detect the chase portion 7b of the bobbin 7 (S7-No), the control unit 90 outputs an empty bobbin discharge signal. It transmits to the winding unit 1 (S10), and controls to discharge the empty bobbin from the rear side of the winding unit 1 (S11). When the bobbin holding device 70 of the winding unit 1 receives the empty bobbin discharge signal, the bobbin 7 can be discharged from the second bobbin discharge position 96 as shown in FIG. Until the bobbin holding portion 20 is rotated and the second probe 81 of the bobbin discharge portion 25 is operated to the rear side of the winding unit 1. As a result, the empty bobbin is discharged to the second bobbin discharge position 96 (S12).

  By controlling as described above, the winding unit 1 causes the bobbin with remaining yarn around which the yarn 8 is wound to the first bobbin discharging position 95, and the empty bobbin where all the yarn 8 is unwound to the second bobbin discharging position 96. Can be discharged separately. In other words, the bobbins 7 can be sorted by the presence or absence of the wound yarn 8. In the above control, the presence or absence of the yarn 8 wound around the bobbin 7 is detected by the yarn detection device 14 provided near the lower end of the balloon controller 10, but the winding of the package 9 measured by the constant length device is performed. The presence / absence (remaining amount) of the yarn 8 wound around the bobbin 7 may be detected from the take-up length.

  The winding unit 1 includes a counter (not shown) that counts the number of empty bobbins discharged and the number of remaining bobbins discharged. Further, the winding unit 1 is provided with an alarm device (not shown) that urges the operator to warn the operator when the discharge quantity of the bobbin with remaining yarn counted by the counter is larger than the discharge quantity of the empty bobbin by a predetermined ratio or more. It has.

  Next, the case where the discharge direction of the bobbin 7 is selected according to the quality of the yarn 8 wound around the bobbin 7 will be described. FIG. 13 is a flowchart in the case where the discharge direction of the bobbin 7 is selected according to the quality of the yarn 8 wound around the bobbin 7.

  The automatic winder 100 uses a control program preset by the operator to, for example, take up the bobbin with take-up remaining yarn to the first bobbin discharge position 95 on the front side of the take-up unit 1 and wind the bobbin with defective remaining yarn into the take-up unit 1. Each discharge direction is selected to the second bobbin discharge position 96 on the rear side. Thereafter, the bobbin with take-up remaining yarn is discharged to the first bobbin discharge position 95 on the front side of the winding unit 1, and the bobbin with defective remaining yarn is discharged to the second bobbin discharge position 96 on the rear side of the winding unit 1. The case will be described.

  When the winding unit 1 starts the winding operation (S20), the yarn clearer 13 detects the presence or absence of a defective portion of the yarn 8 (S21). When the yarn clearer 13 detects a defective portion of the yarn 8 (S21—Yes), the yarn clearer 13 transmits a defect detection signal to the control unit 90. The controller 90 determines whether or not the defect detection signal transmitted from the yarn clearer 13 is generated at a predetermined frequency (S22). When the defect detection signal is not generated with a predetermined frequency (S22-No), the winding unit 1 continues the winding operation (S20).

  When the yarn clearer 13 detects a defective portion of the yarn 8 (S21-Yes) and the defect detection signal is generated at a predetermined frequency (S22-Yes), the control unit 90 outputs a bobbin discharge signal with a defective remaining yarn. Transmission is made to the winding unit 1 (S23), and the bobbin with defective remaining yarn is controlled to be discharged from the rear side of the winding unit 1 (S24). As shown in FIG. 8, the bobbin holding device 70 of the winding unit 1 receives the bobbin discharge signal with defective residual yarn, and as shown in FIG. 8, the bobbin 7 can be discharged from the second bobbin discharge position 96. The bobbin holding unit 20 is rotated to the second holding position, and the second probe 81 of the bobbin discharging unit 25 is operated to the rear side of the winding unit 1. As a result, the bobbin with defective remaining yarn is discharged to the second bobbin discharge position 96 (S25).

  When the yarn clearer 13 does not detect a defective portion of the yarn 8 (S21-No), the yarn detection device 14 detects the chase portion 7b of the bobbin 7 (S26). When the yarn detection device 14 does not detect the chase portion 7b of the bobbin 7 (S26-No), the control unit 90 transmits an empty bobbin discharge signal to the winding unit 1 (S27), and from the rear side of the winding unit 1 Control is performed to discharge the empty bobbin (S24). When the bobbin holding device 70 of the winding unit 1 receives the empty bobbin discharge signal, the bobbin 7 can be discharged from the second bobbin discharge position 96 as shown in FIG. Until the bobbin holding portion 20 is rotated and the second probe 81 of the bobbin discharge portion 25 is operated to the rear side of the winding unit 1. As a result, the empty bobbin is discharged to the second bobbin discharge position 96 (S25).

  When the yarn clearer 13 does not detect the defective portion of the yarn 8 (S21-No) and the yarn detection device 14 detects the chase portion 7b of the bobbin 7 (S26-Yes), the control unit 90 performs the yarn splicing. It is determined whether or not the winding work can be continued (S28). When it is determined that the winding operation can be continued (S28-Yes), the winding unit 1 continues the winding operation (S20).

  When it is determined that the winding operation cannot be continued (S28-No), the control unit 90 transmits a bobbin discharge signal with a take-up remaining yarn to the winding unit 1 (S29), and the front side of the winding unit 1 The bobbin with take-up remaining thread is controlled to be discharged from (S30). The bobbin holding device 70 of the winding unit 1 receives the bobbin discharge signal with the take-up remaining yarn, and as shown in FIG. 7, the bobbin 7 can be discharged to the first bobbin discharge position 95 (described above). The bobbin holding portion 20 is rotated to the first holding position), and the first probe 71 of the bobbin discharge portion 25 is operated to the front side of the winding unit 1. As a result, the bobbin with windable remaining yarn is discharged to the first bobbin discharge position 95 (S31).

  By controlling as described above, the winding unit 1 separately discharges the bobbin with take-up residual yarn to the first bobbin discharge position 95 and the bobbin with defective residual yarn to the second bobbin discharge position 96. be able to. That is, the bobbins 7 can be distributed according to the quality of the wound yarn 8. Further, since only the bobbin with take-up remaining yarn is discharged to the first bobbin discharge position 95 provided on the front side of the take-up unit 1, before the bobbin with take-up remaining yarn can be collected by the bobbin collecting unit 4, Since the operator can collect the bobbin with a take-up remaining yarn and re-store the bobbin with the take-up remaining yarn in the bobbin storage device 50 on the spot, work efficiency can be improved. In this control, the bobbin with a defective remaining yarn and the empty bobbin that has been unwound after all the yarns 8 are unwound at the second bobbin discharge position 96 are discharged together. The seed bobbins are not collected by the operator on the spot and re-stored in the bobbin storage device 50, so there is no problem even if they are mixed and discharged. Moreover, since the bobbin with a take-up remaining thread can be re-stored in the bobbin storage device 50 as described above, the bobbin may be stored on the front side of the winding unit 1 without being conveyed to the bobbin collecting unit 4. In that case, instead of the first conveyor 3 </ b> A of the first bobbin transport unit 2, it is possible to adopt a configuration in which a cage (box) -like storage unit is provided.

  From the above, the bobbin holding unit 20 of the winding unit 1 and the bobbin discharge so that the control unit 90 discharges the bobbin 7 to different discharge positions according to the detection results of the yarn clearer 13 and the yarn detection device 14. Since the unit 25 is controlled, the bobbins 7 can be distributed to different discharge positions according to the state of the bobbin 7 (the presence or absence of yarn, quality, etc.). Therefore, the bobbins 7 having different states can be separated and collected, and the work efficiency in the collection can be improved.

  Next, a second embodiment of the automatic winder 100 of the present invention will be described.
