The holders 72 may be arranged with an interval in the extending direction of the connection type conveyance unit 71 or may be arranged without an interval. The arrangement of the holder 72 can be appropriately set according to the arrangement of the spinning unit 32.

  The first transfer device 70 is further arranged outside the connection type conveyance unit 71 and connected to the carry-out conveyor 73 capable of receiving the tray 6 from the holder 72 and outside the connection type conveyance unit 71 and more than the carry-out conveyor 73. And a carry-in conveyor 74 that is disposed on the downstream side in the moving direction of the mold transport unit 71 and can deliver the tray 6 to the connected mold transport unit 71. The carry-out conveyor 73 and the carry-in conveyor 74 may include, for example, a flat belt or a round belt. The carry-out conveyor 73 and the carry-in conveyor 74 are arranged in parallel, for example. A plurality of path defining plates 76 are arranged above the carry-out conveyor 73 and the carry-in conveyor 74, and the edges of the path defining plate 76 extend in parallel with a certain distance from each other, whereby the carry-out path of the yarn feeding bobbin 11 In addition, a carry-in route for the threadless bobbin 12 is formed. The separation distance of the path defining plate 76 is slightly larger than the outer diameter of the placing portion 64 of the tray 6.

  A tray guide part 77 is provided on the upstream side of the carry-out conveyor 73 in the carrying direction, that is, on the connection-type carrying part 71 side so as to project on the passage path of the holder 72. The tray guide portion 77 is fixed to a surrounding frame or the like, and the protruding tip of the tray guide portion 77 can come into contact with the placement portion 64 of the tray 6. The tray guide unit 77 regulates the movement of the tray 6 in the moving direction of the connection type conveyance unit 71 and guides the tray 6 to the carry-out conveyor 73 side.

  Further, the tray 6 with the threadless bobbin 12 coming out from the second outlet 121 is conveyed toward the fitting recess 72a of the holder 72, and the placing portion 64 of the tray 6 is inserted into the fitting recess 72a. The fitting recess 72a of the holder 72 expands due to elastic deformation when the mounting portion 64 of the tray 6 is pressed against the fitting recess 72a by the restriction of the path defining plate 76, and the mounting portion 64 of the tray 6 is further inserted. Is done. When the mounting portion 64 of the tray 6 is further inserted, the pressure due to the restriction of the path defining plate 76 is eliminated, and the deformed fitting recess 72a is restored to its original shape by the elastic force. Thereby, the mounting portion 64 of the tray 6 is fitted into the fitting recess 72a.

  At the end of the spinning machine 3 on the bobbin transfer device 5 side, a first outlet 111 from which the tray 6 is carried out and a first inlet 112 that receives the tray 6 from the bobbin transfer device 5 are provided. More specifically, a first outlet 111 is provided at the downstream end of the carry-out conveyor 73 in the conveyance direction, and a first inlet 112 is provided at the upstream end of the carry-in conveyor 74 in the conveyance direction. The interval or pitch between the first outlet 111 and the first inlet 112 is substantially equal to the interval or pitch between the second inlet 122 and the second outlet 121.

  The first outlet 111 and the second inlet 122 of the bobbin transfer device 5 are close to each other and face each other. The height of the end portion of the carry-out conveyor 73 constituting the first outlet 111 and the height of the upper surface of the pulley 92 constituting the second inlet 122 are substantially equal. As a result, the first outlet 111 and the second inlet 122 are directly connected. The first inlet 112 and the second outlet 121 of the bobbin transfer device 5 are close to each other and face each other. The height of the end portion of the carry-in conveyor 74 constituting the first inlet 112 and the height of the upper surface of the pulley 92 constituting the second outlet 121 are substantially equal. Thus, the first inlet 112 and the second outlet 121 are directly connected. With such a configuration, the second inlet 122 can receive the tray 6 and the yarn feeding bobbin 11 carried out from the first outlet 111 of the first transfer device 70. The tray 6 and the threadless bobbin 12 transferred from the automatic winder 4 can be carried out from the second outlet 121 toward the first inlet 112.

  Here, operation | movement of the 1st transfer apparatus 70 and the 2nd transfer apparatus 50 is demonstrated. The control device 31 of the spinning machine 3 can drive and control the first transfer device 70. The control device 41 of the automatic winder 4 can drive and control the second transfer device 50. The first transfer device 70 and the second transfer device 50 are driven in synchronization with each other by the control device 31 and the control device 41. In other words, the tray 6 is exchanged between the first transfer device 70 and the second transfer device 50 in a one-to-one correspondence relationship.

  In the yarn winding system 1, the control device 31 controls the first transfer device 70 to transfer the yarn feeding bobbin 11 in a state of being placed on the tray 6, and to the second transfer device 50 of the bobbin transfer device 5. The tray 6 and the yarn feeding bobbin 11 are directly delivered. In response to this, the control device 41 controls the second transfer device 50 to transfer the yarnless bobbin 12 in a state of being placed on the tray 6, and to the first transfer device 70 of the spinning machine 3 with respect to the tray. 6 and threadless bobbin 12 are delivered directly.

  Thus, in the yarn winding system 1, the tray 6 and the yarn feeding bobbin 11 are quickly supplied to the bobbin transfer device 5 in response to a request from the control device 41, and at the same time, the tray 6 and the yarnless bobbin 12 are moved to the spinning machine 3. Will be returned. As described above, the yarn winding system 1 includes a staying device (in other words, a device serving as a buffer) that temporarily holds the tray 6 without being synchronized with the first transfer device 70 and the second transfer device 50. Not provided.

  According to the yarn winding system 1 and the yarn winding method of the present embodiment, the yarn feeding bobbin 11 is transferred in a state of being placed on the tray 6 by the first transfer device 70 of the spinning machine 3 and is discharged from the first outlet 111. Is done. Since the first outlet 111 is directly connected to the second inlet 122 of the bobbin transfer device 5, the yarn feeding bobbin 11 is quickly transferred from the spinning machine 3 to the bobbin transfer device 5. Further, the threadless bobbin 12 is transported while being placed on the tray 6 by the second transport device 50, and is unloaded from the second outlet 121. Since the second outlet 121 is directly connected to the first inlet 112 of the spinning machine 3, the yarnless bobbin 12 is quickly transferred from the bobbin transfer device 5 to the spinning machine 3. In the bobbin transfer device 5, a predetermined process is performed on the yarn supplying bobbin 11 or the yarnless bobbin 12. As described above, since a buffering device for temporarily retaining the yarn feeding bobbin 11 or the yarnless bobbin 12 is not provided between the spinning machine 3 and the bobbin transfer device 5, an increase in the size of the yarn winding system 1 is suppressed. ing.
