  • the spinning unit 32 When a sensor is provided in each of the spinning units 32, the spinning unit 32 allows the winding information indicating the winding state output from the sensor to be written on the RF tag 63.
  • the RF tag 63 is then read in the winder unit 42 of the automatic winder 4 whereby the winding information can be acquired.
  • the spinning unit 32 allows identification information that can uniquely identify the formed yarn supply bobbin 11 to be written on the RF tag 63 and outputs the identification information linked to the winding information to the communication unit 31c.
  • the communication unit 31c transmits the winding information output from each of the spinning units 32 to the automatic winder 4.
  • the identification information is read from the RF tag 63 on the yarn supply bobbin 11 in the winder unit 42, and the corresponding winding information is acquired from among a plurality of winding information received by the communication unit 41c, based on the identification information.
  • the winding information indicating the winding state detected by the sensor is transmitted from the communication unit 31c of the spinning frame 3 to the automatic winder 4.
  • a predetermined number of sensors are provided, a plurality of winding information output from the sensors are subjected to predetermined processing (for example, averaging) and output as a piece of winding information from the communication unit 31c.
  • winding information indicating the pitch of winding of yarn 14 in the yarn supply bobbin 11, information indicating the tightness of winding of yarn 14 in the yarn supply bobbin 11, and information indicating the yarn tension during winding of yarn 14 in the yarn supply bobbin 11 have been described as the winding information by way of example.
  • the winding information may not include these three pieces of information or may include information other than these three pieces of information.
  • the manner in which the winding information is directly transmitted from the communication unit 31c of the spinning frame 3 to the communication unit 41c of the automatic winder 4 has been described by way of example.
  • the method of acquiring the winding information in the automatic winder 4 is not limited to this manner.
  • the winding information output from the communication unit 31c may be acquired by the communication unit 41c through another device (for example, a server device).
  • the manner in which the winding information is acquired by the automatic winder 4 through communication between the communication unit 31c of the spinning frame 3 and the communication unit 41c of the automatic winder 4 has been described by way of example.
  • the acquisition of the winding information is not limited to communication.
  • the winding information may be written on the RF tag 63 in the tray 6 in which the yarn supply bobbin 11 is set. In this configuration, the winding information is read by the RF reader 49 and transmitted to the unit controlling unit 52 of the automatic winder 4.
  • the unit controlling unit 52 may include a communication unit (acquisition unit).
  • the manner in which the control device 31 of the spinning frame 3 includes the communication unit 31c has been described by way of example, the spinning unit 32 may include a communication unit (output unit).
