  • the endless belt 53 spans at least from the first discharge path 43 to the front portion of the individual path 42 in the front-rear direction (see FIG. 3 ). That is, the transportation force also acts on the tray T located at the front portion of the individual path 42. The transportation force has a component directed to the downstream side in the transport direction of the individual path 42.

  • the tray T on which the discharged bobbin Bd has been mounted is transported along the first discharge path 43 by the first conveyor mechanism 50 of the tray transport device 8.
  • the tray T is transported, for example, at a transport speed (hereinafter, "first transport speed") set by the setting section 5a of the main controller 5 and stored in the storage section 5b.

  • the tray T is transported along the second discharge path 32 by the second conveyor mechanism 60 of the bobbin processing device 3.
  • the main controller 5 determines whether the tray T stays on the second discharge path 32 of the bobbin processing device 3 based on the detection signal output by the tray sensor 38 (Step S101). In the present embodiment, when the tray T is continuously detected by the tray sensor 38 for a predetermined time or longer (for example, 0.5 seconds or longer), the main controller 5 determines that the tray T has stayed. In a normal state (for example, the above-mentioned initial state), the time during which the tray sensor 38 detects the tray T passing in front of the tray sensor 38 is very short. For this reason, the main controller 5 determines that the tray T has not stayed (Step S101: No). In this case, the main controller 5 continues to determine whether the tray T is staying.
  • a predetermined time or longer for example, 0.5 seconds or longer
  • a large number of trays T may form a queue on the return path 34 and the second discharge path 32 of the bobbin processing device 3 (see FIG. 9B ).
  • the tray T will be detected continuously by the tray sensor 38 for 0.5 seconds or longer.
  • the main controller 5 determines that the tray T has stayed (Step S101: Yes). In this case, the main controller 5 stops the operation of the first conveyor mechanism 50 by stopping the first motor 54 while operating the second conveyor mechanism 60 (Step S102).
  • the main controller 5 also transmits a signal indicating that the tray T has stayed to each unit control section 12 (Step S102). Even after stopping the first conveyor mechanism 50, the operation of the second conveyor mechanism 60 is continued. Thus, the tray T on the first discharge path 43 can be made to standby without being transported until the staying of the tray T on the second discharge path 32 is resolved. For this reason, it can suppress that the trays T accumulate on the first discharge path 43 (in particular, on the downstream side in the transport direction). In the present embodiment, the main controller 5 stops the first motor 54 and transmits to each unit control section 12 the signal indicating that the tray T has stayed.
  • each unit control section 12 and the main controller 5 can exchange signals in parallel in case the unit control sections 12 and the main controller 5 are capable of communicating at any time.
  • one of the unit control sections 12 may stop the first motor 54 and transmit to the main controller 5 the signal indicating that the tray T has stayed.
  • the unit control section 12 Upon receiving the signal indicating that the tray T has stayed from the main controller 5, the unit control section 12 performs the following process.
  • the unit control section 12 starts counting the number of trays T discharged from the winding unit 7 after receiving the above signal.
  • the discharge of the tray T by the ejector 29 is prohibited. This prevents the individual path 42 or the junction between the individual path 42 and the first discharge path 43 from being clogged with the tray T while the operation of the first conveyor mechanism 50 is stopped.
  • This upper limit is preferably set based on the number of trays T that can be temporarily stored on the discharged-bobbin storage path 46.
  • the main controller 5 determines whether the staying of the tray T on the second discharge path 32 has been resolved (Step S103). For example, after stopping the operation of the first conveyor mechanism 50, the main controller 5 determines that the staying of the tray T has been resolved when the tray sensor 38 does not detect the tray T for the first predetermined time or longer. (Step S103: Yes). If the staying of the tray T has not been resolved, the main controller 5 continues to determine whether the staying of the tray T has been resolved. Also, it is preferable that the first predetermined time can be changed according to the set value of the transport speed at which the trays T are transported by the second conveyor mechanism 60.
  • the first predetermined time can be set short.
  • the tray T on the second discharge path 32 does not move easily, therefore, it is better to lengthen the first predetermined time in order to suppress the occurrence of staying of the tray T again.
  • the main controller 5 determines that the staying of the tray T on the second discharge path 32 has been resolved, the main controller 5 causes the first motor 54 to operate again, and resumes the operation of the first conveyor mechanism 50 (Step S104).
  • the main controller 5 sets the transport speed at which the first conveyor mechanism 50 transports the tray T to a second transport speed slower than the first transport speed (see FIG. 9C ). This prevents the tray T moving from the first discharge path 43 of the tray transport device 8 to the second discharge path 32 of the bobbin processing device 3 from quickly catching another tray T remaining on the second discharge path 32. Further, the main controller 5 transmits to each unit control section 12 a signal indicating that the staying of the tray T has been resolved (Step S104).
  • the unit control section 12 Upon receiving this signal, the unit control section 12 resets the count of the number of trays T that have been discharged from the winding unit 7. If the unit control section 12 has prohibited the trays T from being discharged from the winding unit 7 because the number of discharged trays T has reached the upper limit, upon receiving the above signal, the discharging of the trays T from the winding unit 7 is allowed.
  • the main controller 5 determines whether the state in which the staying of the tray T has been resolved has continued for the second predetermined time or longer (Step S105). If the tray T stays again (Step S106: Yes) before the second predetermined time has elapsed (Step S105: No), the process procedure is returned to Step S102. Also, the timer that measures the second predetermined time is reset.
  • Step S106: No If the state in which the tray T is not staying (Step S106: No) continues for the second predetermined time or longer, that is, if the detection interval of the trays T is longer than the set time, the main controller 5 determines that the staying of the tray T has been resolved, and also determines that the state in which the trays T are transported without a gap therebetween is also resolved (Step S105: Yes). In this case, the main controller 5 returns the transport speed at which the first conveyor mechanism 50 transports the tray T from the second transport speed to the first transport speed. As explained above, the main controller 5 performs the processing when the tray T stays on the second discharge path 32 of the bobbin processing device 3.
  • FIGS. 10A and 10B are views for explaining the movement of the trays T on the individual path 42.
  • the second tray T2 is pressed orthogonally against the guide surface 75, there is a possibility that the second tray T2 may not move to either the upstream side or the downstream side in the transport direction.
  • the direction in which the pressing force acts and the direction of extension of the second guide surface 77 form an obtuse angle. Therefore, the second tray T2 is pushed toward the upstream side in the transport direction because of a component of the pressing force that is parallel to the second guide surface 77. Therefore, because of such a pressing force, the second tray T2 is likely to be pushed toward the upstream side in the transport direction against the transportation force imparted by the first conveyor mechanism 50 (see an arrow 105 shown in FIG. 7 ).
  • the shaft portion Tb of the second tray T2 is in contact with the first guide surface 76.
  • the direction of extension of a straight line 106 connecting the axial center of the second tray T2 and the axial center of the first tray T1 is inclined with respect to a direction orthogonal to the direction of extension of the first guide surface 76.
  • the second tray T2 is pushed toward the downstream side (away from the protrusion 78) in the transport direction of the first partial path 47 because of a component of the pressing force (see an arrow 107 shown in FIG. 10A ) that is parallel to the first guide surface 76. Therefore, the second tray T2 is easily pushed toward the downstream side in the transport direction because of the pressing force and the transportation force imparted by the first conveyor mechanism 50 (see an arrow 108 shown in FIG. 10A ).
  • the second tray T2 on the individual path 42 is in contact with the first tray T1 on the first discharge path 43, the second tray T2 is moved away from the protrusion 78. That is, when the second tray T2 is in contact with the apex 79 of the protrusion 78 or is positioned on the second partial path 48 on the upstream side in the transport direction, the second tray T2 is pushed further toward the upstream side. Also, when the second tray T2 is positioned on the first partial path 47 on the downstream side in the transport direction, the second tray T2 is further pushed toward the downstream side. Therefore, even if the second tray T2 is located on the individual path 42, the occurrence of the bridge phenomenon is suppressed.
  • the first conveyor mechanism 50 is driven by the first drive source (the first motor 54), and the second conveyor mechanism 60 is driven by the second drive source (the second motor 64). Furthermore, when it is determined that the tray T discharged from the winding unit 7 is staying on the second discharge path 32 of the bobbin processing device 3, only the operation of the first conveyor mechanism 50 is stopped. In this manner, the tray T on the first discharge path 43 of the tray transport device 8 is caused to stand by without being transported until the staying of the tray T on the second discharge path 32 is resolved as a result of operating the second conveyor mechanism 60.
  • the tray T can be suppressed from accumulating on the first discharge path 43 (in particular, a downstream side portion of the transport direction), so that the occurrence of the bridge phenomenon, the operation stop of the winding unit 7, and the like can be suppressed. Therefore, iL is possible to suppress the occurrence of a problem caused by the staying of the tray T in the bobbin processing device 3.
  • the operation of the first conveyor mechanism 50 is resumed. For this reason, compared with, for example, the case in which the operation of the first conveyor mechanism 50 is resumed after the predetermined time has elapsed or by an operation performed by the operator, it is possible to avoid the occurrence of useless operation, the reduction in the production efficiency, and the like.
  • the tray sensor 38 does not detect the tray T for the first predetermined time or longer, it is determined that the staying of the tray T on the second discharge path 32 has been resolved. As a result, the operation of the first conveyor mechanism 50 can be resumed while there is some open space near the tray sensor 38. Therefore, it is possible to prevent the operation of the first conveyor mechanism 50 from being stopped again in a short time after the resuming of the operation of the first conveyor mechanism 50.
  • the second transport speed when the operation of the first conveyor mechanism 50 is resumed is slower than the first transport speed. Therefore, it is possible to prevent the tray T that has moved from the first discharge path 43 of the tray transport device 8 to the second discharge path 32 of the bobbin processing device 3 from quickly catching another tray T remaining on the second discharge path 32. Therefore, it is possible to prevent staying again of the tray T on the second discharge path 32.
  • the transport speed of the first conveyor mechanism 50 is returned from the second transport speed to the first transport speed.
  • the number of trays T discharged from the winding unit 7 while the operation of the first conveyor mechanism 50 is stopped is limited. Therefore, it is possible to prevent the individual path 42 or the junction of the individual path 42 and the first discharge path 43 from being clogged with the tray T while the operation of the first conveyor mechanism 50 is stopped.

That is, if the staying of the discharged tray on the second discharge path has not been resolved, the operation of the first conveyor mechanism will be stopped immediately after being resumed, and a wasteful operation will be performed. Also, if the staying of the discharged tray on the second discharge path is resolved before the predetermined time has elapsed, the first conveyor mechanism will be stopped longer than necessary, and the production efficiency will be reduced. In the above aspect, because the operation of the first conveyor mechanism is resumed after it is determined whether the staying of the discharged tray on the second discharge path has been resolved, the above problem can be avoided.
