  • the yarn processing facility is arranged to be able to support two yarn supply packages (e.g., a first yarn supply package and a second yarn supply package) for one winding bobbin.
  • a mechanical control unit for controlling the above-described yarn processing facility is configured to determine from which yarn supply package a yarn is supplied from a wound package (i.e., to associate individual information of a wound package with individual information of a yarn supply package).
  • a tag of individual information of each yarn supply package and a location identification tag indicating the location of a package attachment unit (a first attachment unit or a second attachment unit) to which the yarn supply package is attached are read by an identification device. Based on a result of identification by the identification device, individual information of a yarn supply package is associated with a package attachment unit.
  • the yarn processing facility includes a detector for detecting a node.
  • the mechanical control unit When from which yarn supply package a yarn is supplied is known (e.g., when it is known that a yarn is supplied from a first yarn supply package), the mechanical control unit performs the following determinations. When a node is not detected by the detector during a period from the start of winding of the yarn onto the winding bobbin to the end of the winding, it is determined that only the yarn in the first yarn supply package is supplied to the winding bobbin. When a node is detected by the detector during a period from the start of winding of a yarn onto a winding bobbin to the end of the winding, it is determined that both the yarn in the first yarn supply package and the yarn in the second yarn supply package are supplied to the winding bobbin.
  • information of association between individual information of a wound package and individual information of a yarn supply package is acquired based on a result of identification by the identification device and a result of detection by the detector. It is, however, difficult to acquire further detailed information based only on the identification result and the detection result.

  • the management output unit 101b is equivalent to an output unit of the present invention.
  • the types of the charts are not limited to those described above. Any types of charts may be output as long as an unwinding period of each yarn supply package Ps and a winding period of each wound package Pw can be visually checked by an operator. This allows the operator to easily associate yarn supply package individual information with wound package individual information. In addition to the information shown in FIG. 5(a) to FIG. 5(c) , the charts may show further detailed information.
  • the management output unit 101b has a printer, the information management unit 110 may print the charts by the printer. Alternatively, the information management unit 110 may output (display) the charts to the machine output unit 5b of the machine controller 5. Alternatively, the output controller configured to generate chart data and the output unit configured to output the charts may be provided independently from the information management unit 110.
  • the information management unit 110 it is possible to know an unwinding start time of each yarn supply package Ps by the information management unit 110. Furthermore, by acquiring the replacement time information, it is possible to know a winding start time and a winding end time of each wound package Pw. It is therefore possible to acquire various types of information regarding the relationship between a winding bobbin Bw (wound package Pw) and a yarn supply package Ps. For example, it is possible to know from which layer of a yarn Y of a yarn supply package Ps a wound package Pw is formed. Furthermore, it is possible to determine whether a node K has been mixed into a wound package Pw. In this regard, moreover, it is possible to know in which part of the wound package Pw the node K has been mixed. As such, various types of useful information can be obtained.
  • the yarn supply package individual information and the unwinding start time information are acquired in association with each other.
  • the operator can easily associate the wound package individual information with the yarn supply package individual information only by checking output charts.
