  • the present invention relates to a carrier distributing device that distributes a carrier used to transport a yarn supplying bobbin to two transportation paths, and particularly relates to a carrier distributing device that distributes a carrier with respect to two transportation paths extending toward two bobbin attaching units of a bobbin attaching device.
  • a bobbin transporting system that attaches a bobbin wound with a yarn to a carrier, and transports the carrier attached with the bobbin to supply the bobbin to a winding unit.

  • a bobbin attaching device for attaching the bobbin to the carrier is arranged in the above-described bobbin transporting system.
  • the transportation path of the above-described bobbin transporting system includes a branched portion provided upstream in a transporting direction of the bobbin attaching device, two parallel transportation paths provided at positions corresponding to the two bobbin attaching units, and a merging portion provided downstream in the transporting direction of the bobbin attaching device. According to such a structure, the carriers are distributed from one transportation path to two transportation paths, and then are transported toward the bobbin attaching device.
  • JP S61 197376 A discloses a bobbin pitch varying apparatus for a bobbin transport body.
  • the apparatus comprises a transport rail having a wide width at a position corresponding to a machine base of a fly frame and a narrow width at a part ranging from an intermediate part to a transport passage for a preparatory bobbin.
  • a pair of rollers are installed rotatably on the right and left sides of a bobbin transport body which can travel on the rail, and a supporting member suspending a bobbin hanger is connected to the undersurface by a link.
  • a turning lever is rotatably supported onto a supporting shaft installed in projection onto the under surface of the rail, and when the rail is shifted to the wide part from the narrow width part, the engaging roller of the supporting member at the top edge is shifted to the guide rail side by a guide part of the lever, and the lever is alternately turned in zigzag form.
  • DE 10 2016 201358 A1 discloses an apparatus for distributing bobbins, wherein a bobbin passage is adapted to transport an infeed bobbin and a bobbin distribution area is adapted to disperse the bobbin from the bobbin passage to a plurality of supply paths.
  • the carriers are preferably distributed evenly to the two parallel transportation paths.
  • EP 2465801 B1 only describes the arrangement of the two bobbin attaching units, and does not disclose a technique of evenly distributing the carriers to the two parallel transportation paths.
  • a carrier distributing device is a device that distributes a carrier with respect to a bobbin attaching device including two bobbin attaching units, and includes a carrier transportation path and a distributing member.
  • the carrier transportation path includes a carrier introducing portion, a branched portion continuing to the carrier introducing portion, a first transportation path and a second transportation path branched from the branched portion and extended toward the two bobbin attaching units, and a merging portion where the first transportation path and the second transportation path merge.
  • the distributing member is a member arranged at the branched portion to distribute the carrier to the first transportation path and the second transportation path.
  • the distributing member can change an orientation between a first orientation of guiding the carrier to the first transportation path and a second orientation of guiding the carrier to the second transportation path.
  • the distributing member is changed from the first orientation to the second orientation by the carrier after guiding the carrier to the first transportation path, and is changed from the second orientation to the first orientation by the carrier after guiding the carrier to the second transportation path.
  • the carrier is movable to the second transportation path through the branched portion regardless of whether the distributing member is in the first orientation or the second orientation.
  • the carrier is moved from the carrier introducing portion to the branched portion, and alternately, that is, evenly distributed to the first transportation path and the second transportation path by the distributing member.
  • the reason for alternately distributing the carrier is because the distributing member is changed from the first orientation to the second orientation after distributing the carrier to the first transportation path, and is changed from the second orientation to the first orientation after distributing the carrier to the second transportation path.
  • the orientation of the distributing member is changed by the carrier to be transported. Therefore, a member (e.g., spring, solenoid) for driving the distributing member is not necessary. In other words, the distributing operation is achieved by a simple structure.
  • the distributing member may include a main body portion, a contact guiding portion, a first swing contacting portion, and a second swing contacting portion.
  • the main body portion is swingable.
  • the contact guiding portion is arranged on the main body portion, and makes contact with the carrier when the carrier approaches the distributing member from the carrier introducing portion, and thereafter, guides the carrier.
  • the first swing contacting portion is formed on the first transportation path side with respect to the contact guiding portion in the main body portion.
  • the second swing contacting portion is formed on the second transportation path side with respect to the contact guiding portion in the main body portion.
  • the distributing member When the carrier is brought into contact with the second contacting portion while the carrier is moving on the second transportation path in the second orientation, the distributing member is swung to change from the second orientation to the first orientation.
  • the distributing member can distribute the carrier evenly to the first transportation path and the second transportation path by simply being swung between the first orientation and the second orientation.
  • the carrier distributing device may further include a first driving unit, a second driving unit, a carrier sensor, and a controller.
  • the first driving unit drives the first transportation path.
  • the second driving unit drives the second transportation path.
  • the carrier sensor detects a state of the carrier at the merging portion.
  • the controller controls the first driving unit to move backward/stop the first transportation path, and when subsequently determining that the bridge of the carrier is resolved at the merging portion according to a detection signal from the carrier sensor, the controller controls the first driving unit to moves forward the first transportation path.
  • the carrier distributing device may further include a first cutout device and a second cutout device arranged on the first transportation path and the second transportation path, respectively, to continuously execute stopping and releasing of forward movement on the carrier.
  • the controller cancels a cutout operation of the first cutout device and the second cutout device before backward moving/stopping the first transportation path or the second transportation path when determining that the bridge of the carrier occurred at the merging portion according to a detection signal from the carrier sensor, and starts the cutout operation of the first cutout device and the second cutout device after forward moving the first transportation path or the second transportation path.
  • the cutout operation of the first cutout device and the second cutout device is canceled before the operation of resolving the bridge of the carrier at the merging portion is carried out. Therefore, a great number of carriers do not move toward the merging portion, and hence, the bridge of the carrier at the merging portion is reliably and quickly resolved.
  • the distributing member is a plate-shaped piece. Therefore, a space occupied by the distributing member is small.
  • a limiting mechanism that limits a swing angle of the distributing member is arranged. Therefore, the orientation of the distributing member is accurately maintained by limiting the swing angle of the distributing member.
  • the contact guiding portion has a substantially triangular shape in plan view, and includes a distal end portion, a first receiving side on the first transportation path side, and a second receiving side on the second transportation path side. Therefore, the shape of the distributing member is simple.
  • the carrier includes a circular column portion with a seating surface, on which the bobbin is seated, and an outer peripheral surface, to which the distributing member makes contact. Therefore, a general carrier can be used as it is.
  • the carrier sensor detects whether or not a carrier is transported beyond the merging portion. Therefore, the controller can accurately determine whether the bridge of the carrier has occurred at the merging portion.

In such a case, the carrier 3 that approaches the branched portion 37 next makes contact with the stopped carrier 3 to be guided to the second transportation path 39. That is, the transportation guide (guiding path 21) is formed by the layout of the guiding path 21 so that the operations described above are executed. This is the same regardless of whether the distributing member 41 is in the first orientation A, as shown in FIG. 16 , or the distributing member 41 is in the second orientation B, as shown in FIG. 17 .
  • the carrier 3 is guided to the second transportation path 39 when the carriers 3 are full and stagnated in the first transportation path 38. Therefore, the transportation efficiency of the carrier 3 at the branched portion 37 is less likely to lower.
  • FIG. 18 is a block diagram showing the control configuration of the carrier distributing device.
  • the carrier distributing device 31 includes a controller 57.
  • the controller 57 is a computer system including a processor (e.g., CPU), a storage device (e.g., ROM, RAM, HDD, SSD, and the like), and various types of interfaces (e.g., A/D converter, D/A converter, communication interface, and the like).
  • the control section carries out various control operations by executing a program stored in the storage unit (corresponds to some or all of a storage region of storage device).
  • the controller 57 may be configured with a single processor, but may be configured with a plurality of processors, each being independent for each control.
  • each element of the controller 57 may be realized as a program executable in the computer system configuring the control section. In addition, some of the function of each element of the controller 57 may be configured by a custom IC.
  • the controller 57 is connected to the solid bobbin supplying device 13, the first drive motor 71, the second drive motor 73, the first cutout device 59, and the second cutout device 61. Therefore, the controller 57 can transmit control signals to such devices.
  • the first drive motor 71 drives the first belt conveyor 23A, that is, the first transportation path 38.
  • the second drive motor 73 drives the second belt conveyor 23B, that is, the second transportation path 39.
  • the controller 57 is connected to the carrier sensor 55. Therefore, the controller 57 can accurately determine whether a bridge of the carrier 3 has occurred at the merging portion 51.
  • the carrier sensor 55 checks the passing of the carrier 3 at a point ahead of the merging portion 51.
  • controller 57 is also connected to a sensor that detects the size, shape, and position of the carrier and the bobbin, a sensor and a switch that detect the state of each device, and an information input device.
  • FIG. 19 is a flowchart showing the bridge resolving control of the merging portion of the carrier distributing device.
  • FIGS. 20 to 22 are partial plan views showing the bridge resolving operation at the merging portion.
  • control flowchart described below is illustrative, and each step may be omitted or interchanged as necessary. Furthermore, a plurality of steps may be executed simultaneously, or some or all of the steps may be executed in an overlapping manner.
  • each block of the control flowchart is not limited to a single control operation, and may be replaced with a plurality of control operations represented with a plurality of blocks.
  • the carrier 3 attached with the threaded bobbin tube 5B moves on the first transportation path 38 and the second transportation path 39, and passes through the merging portion 51 to move further downstream.
  • step S1 of FIG. 19 the controller 57 determines whether or not the bridge of the carrier 3 has occurred at the merging portion 51 according to the detection signal from the carrier sensor 55.
  • FIG. 21 shows a state in which the bridge has occurred at the merging portion 51. That is, the carrier 3 does not move further from the merging portion 51, and a state in which the carrier 3 is not detected by the carrier sensor 55 continues. Thus, if the carrier 3 cannot be detected even after elapse of a predetermined time from the execution of the cutout of the carrier 3, the controller 57 determines that the bridge has occurred.
  • step S2 the controller 57 determines whether or not the chute operation is under operating in the solid bobbin supplying device 13. If in the shoot operation is under operating, the termination of the chute operation is waited.
  • step S3 the controller 57 stops the cutout operation of the first cutout device 59 and the second cutout device 61.
  • step S4 the controller 57 reversely rotates the first belt conveyor 23A by reversely rotating the first drive motor 71.
  • the carrier 3 on the first transportation path 38 is moved backward.
  • step S5 the controller 57 stops the first belt conveyor 23A by stopping the first drive motor 71.
  • the carrier 3 on the first transportation path 38 stops while being away from the merging portion 51. That is, the bridge at the merging portion 51 is resolved, and hence the carrier 3 on the second transportation path 39 is moved farther through the merging portion 51.
  • step S6 the controller 57 thereafter determines whether or not the bridge of the carrier 3 is resolved at the merging portion 51 according to the detection signal from the carrier sensor 55.
  • step S7 the controller 57 waits until elapse of a predetermined time. Meanwhile, the discharging of the carrier 3 on the second transportation path 39 from the merging portion 51 is completed.
  • step S8 the controller 57 normally rotates the first belt conveyor 23A by normally rotating the first drive motor 71.
  • the carrier 3 on the first transportation path 38 moves forward, as shown in FIG. 22 .
  • step S9 the controller 57 waits until elapse of a predetermined time. Meanwhile, the discharging of the carrier 3 on the first transportation path 38 from the merging portion 51 is completed.
  • step S10 the controller 57 starts the cutout operation of the first cutout device 59 and the second cutout device 61.
  • the carrier 3 is moved backward/stopped on the first transportation path 38 when the bridge of the carrier 3 occurs at the merging portion 51.
  • the carrier 3 on the first transportation path 38 can be moved forward by resolving the bridge of the carrier 3 at the merging portion 51.
  • the bridge of the carrier 3 at the merging portion 51 is quickly resolved with a simple operation.
  • a specific shape of the distributing member is changed depending on the shape of the branched portion, and is not limited to the embodiment described above.
