  • the fully wound yarn length of a package is order-of-magnitudes longer than the fully wound yarn length of a yarn supplying bobbin that is about 4 kilometers for medium count yarn.
  • the yarn information acquiring device such as the unit control device 3, the machine control device 4, or the management device that is a host control device of the yarn winding machine 1 may acquire the maximum value or the minimum value of the yarn information for each divided yarn length by temporarily storing a maximum value or a minimum value in the current divided yarn length segment from the time when the current divided yarn length segment starts while updating the maximum value or the minimum value as necessary, and determining the value at the time when the current divided yarn length segment ends.
  • the yarn information acquiring section may acquire the cumulative value of the yarn information for each divided yarn length by temporarily stores a cumulative value in the current divided yarn length segment from the time when the current divided yarn length segment starts while updating the cumulative value as necessary, and determining the value at the time when the current divided yarn length segment has ended. Acquiring the yarn information by such methods as described above eliminates the need of storing raw data, and thus the memory can be efficiently used.
  • the yarn information acquiring section may continue to temporarily store pieces of raw data in a predetermined divided yarn length segment from when the divided yarn length segment starts to when the segment ends, may calculate the average value or the median value, for example, based on the pieces of raw data at the time when the predetermined divided yarn length segment has ended, and may discard the raw data after the calculation.
  • the need of storing raw data that is relatively large data can be minimized, and an appropriate value can be obtained while the memory is being efficiently used.
  • a yarn information acquiring device a yarn winding machine, and a textile machine system according to the present disclosure can be obtained as follows.
  • a yarn information acquiring device includes a yarn information acquiring section that, when yarn is wound to form a package in a yarn winding machine, acquires yarn information indicating a state of the yarn by the package.
  • the yarn information acquiring device With this yarn information acquiring device, the yarn information is acquired on a package-by-package basis, and thus if some event occurs in a package in a subsequent process after a process of forming the package, the cause of occurrence of the event can be easily identified.
  • the yarn information acquiring device may further include a yarn information storage section that stores the yarn information by the package.
  • the yarn information acquiring section may acquire the yarn information for each of yarn lengths into which the length of yarn that forms one package is divided.
