  • the bobbin preparing operation of the bobbin preparation device 7 can be appropriately controlled.
  • step S1 operation including a yarn winding method according to the present embodiment
  • step S2 operation including a yarn winding method according to the present embodiment

  • the spinning information received by the receiving unit 41c is delivered to the control device 41.
  • the control device 41 controls the winding speed of each of the winder units 42 (step S4, control step) .
  • the control device 41 calculates the supply pace of each of the yarn supply bobbins 11 on the basis of the processing status information included in the spinning information, and determines the winding speed of each of the winder units 42 such that the supply pace and the pace of a winding process in the winder unit 42 (i.e., discharge pace of the empty bobbin 12) are balanced.
  • the control device 41 then controls operation of each of the winder units 42 so as to wind yarn from the corresponding yarn supply bobbin 11 at the determined winding speed.
  • the RF reader 7a provided to the bobbin preparation device 7 reads doffing information written on the RF tag 63 provided to the corresponding tray 6 transferring the yarn supply bobbin 11, and transmits the doffing information to the control device 41 (step S5).
  • the control device 41 controls the bobbin preparing operation of the bobbin preparation device 7 (step S6, control step). Specifically, as described above, the control device 41 controls operation of the bobbin preparation device 7, for example, based on information on the end of yarn winding in the yarn supply bobbin 11 included in the spinning information.
  • the control device 41 of the automatic winder 4 controls operation of the automatic winder 4 (i.e., operation of each of the winder units 42, and operation of the bobbin preparation device 7, etc.). By controlling the operation of the automatic winder 4 on the basis of the spinning information received from the spinning frame 3 in this manner, operation control of the automatic winder 4 can be optimized.
  • the spinning information includes information on the processing status of forming the yarn supply bobbin 11.
  • the control device 41 determines the winding speed when each of the winder units 42 winds yarn from the corresponding yarn supply bobbin 11, and controls operation of the winder unit 42 so as to wind yarn from the yarn supply bobbin 11 at the determined winding speed.
  • the automatic winder 4 can appropriately control the winding speed of the winder unit 42.
  • the spinning information includes information on a state at the end of yarn winding in a yarn supply bobbin 11 as the information on the condition for completing spinning.
  • the automatic winder 4 includes, in the bobbin transfer device 5 configured to transfer each of the yarn supply bobbins 11 from the spinning frame 3 to the automatic winder 4, the bobbin preparation device 7 configured to perform preliminary preparation for processing yarn of the yarn supply bobbin 11. Based on the information on the end of yarn winding, the control device 41 controls bobbin preparing operation for the yarn supply bobbin 11 in the bobbin preparation device 7.
  • the automatic winder 4 can appropriately control the bobbin preparing operation in the bobbin preparation device 7.
  • the spinning information includes doffing information for identifying timing when a yarn supply bobbin 11 has been formed.
  • Each tray 6 configured to transfer a yarn supply bobbin 11 is provided with the RF tag 63 configured to store therein the doffing information.
  • the bobbin preparation device 7 has the RF reader 7a.
  • the RF reader 7a reads the doffing information stored in the RF tag 63 provided to the tray 6 configured to transfer the yarn supply bobbin 11.
  • the control device 41 controls operation of the bobbin preparation device 7.
  • the condition for completing spinning of a yarn supply bobbin 11 differs depending on timing when a yarn supply bobbin 11 is formed, and yarn supply bobbins 11 that have been formed at different timings are transferred in a mixed manner to the bobbin preparation device 7.
  • operation of the bobbin preparation device 7 can be appropriately controlled.
  • the spinning frame 3 and the automatic winder 4 have the following effects. Specifically, in the spinning frame 3, the spinning information is transmitted to the automatic winder 4, whereby the automatic winder 4 can grasp the information on at least one of the processing status of forming a yarn supply bobbin 11 and the condition for completing spinning in the yarn supply bobbin 11. Thus, in the automatic winder 4, operation control of each of the winder units 42 based on the spinning information can be optimized. In the automatic winder 4, operation of the automatic winder 4 is controlled based on the spinning information received from the spinning frame 3, whereby operation control of the automatic winder 4 can be optimized.
  • transmission of the spinning information from the spinning frame 3 to the automatic winder 4 does not have to be performed directly between the spinning frame 3 and the automatic winder 4, and may be performed via a predetermined repeating device, for example.
  • operation (winding speed) of each of the winder units 42 is controlled based on the processing status information.
  • the control device 41 may control operation of the bobbin preparation device 7, based on the processing status information.
  • preparation operation of the bobbin preparation device 7 is controlled based on the completion condition information.
  • the control device 41 may control operation of each of the winder units 42, based on the completion condition information.
