Definitions

  • the present invention relates to a yarn winding machine and a spinning system.
  • a spinning system including: a spinning frame configured to form a yarn feeding bobbin onto which yarn has been wound; and a yarn winding machine configured to wind yarn of the yarn feeding bobbin transferred from the spinning frame by a bobbin transfer device to form a package is known (see PCT Publication No. WO2018/212293 , for example).
  • quality information on the quality of a yarn feeding bobbin is acquired. Whether the quality of the yarn feeding bobbin satisfies a quality reference value is determined based on the quality information, and when the quality reference value is not satisfied, yarn of the yarn feeding bobbin is prevented from being wound by the yarn winding machine.
  • WO 2019/111090 A1 discloses a method for operating a winding machine for rewinding cops of a preceding ring spinning machine.
  • Decentralized control modules of individual spindle drives capture information about the shape or structure of the cops or about the created thread. This information is transferred to the winding machine and the winding machine takes the received information into consideration when unwinding the cops and producing bobbins.
  • a yarn winding machine is a yarn winding machine configured to wind yarn of a yarn feeding bobbin transferred from a spinning frame by a bobbin transfer device to form a package, and the yarn winding machine includes a controller.
  • the controller acquires first yarn-defect information prepared by the spinning frame about the occurrence of the partial defect.
  • the controller causes winding of the yarn from the yarn feeding bobbin to stop upon determining that the yarn has been unwound from the yarn feeding bobbin up to a position corresponding to the partial defect of the first yarn-defect information, based on yarn information of the yarn wound from the yarn feeding bobbin related to the first yarn-defect information acquired and the first yarn-defect information prepared by the spinning frame, when the first yarn-defect information of the yarn feeding bobbin has been acquired.
  • the yarn up to the position corresponding to the partial defect of the yarn feeding bobbin related to the first yarn-defect information i.e., a portion of yarn having normal yarn quality
  • the first yarn-defect information i.e., a portion of yarn having normal yarn quality
  • the controller causes this yarn feeding bobbin to be discharged as a defective bobbin upon determining, based on the yarn information, that the yarn has been unwound from the yarn feeding bobbin up to the position corresponding to the partial defect of the first yarn-defect information of the yarn feeding bobbin.
  • the yarn having the partial defect of the yarn feeding bobbin can be reliably prevented from being wound. Furthermore, by preventing deletion of a predictable defective portion and successive occurrences of splicing, production efficiency in the yarn winding machine is increased.
  • the first yarn-defect information may be information on yarn breakage in a bottom portion of the yarn feeding bobbin.
  • the yarn up to the bottom portion of the yarn feeding bobbin can be wound without wasting it.
  • the quality of yarn in a bottom portion of a yarn feeding bobbin is more likely to be poor.
  • efficiency decrease when yarn having a partial defect that occurs due to a production problem of the spinning frame is wound by the yarn winding machine can be prevented.
  • the yarn winding machine may further include a yarn-length measuring mechanism configured to acquire, as the yarn information, information on total length of the yarn wound by the yarn winding machine or information on length of the yarn unwound from the yarn feeding bobbin. Based on information on the total length of the yarn wound by the yarn winding machine that the yarn-length measuring mechanism has calculated or information on the length of the yarn unwound from the yarn feeding bobbin that the yarn-length measuring mechanism has measured, the controller may determine that the yarn has been unwound from the yarn feeding bobbin up to the position corresponding to the partial defect of the first yarn-defect information.
  • the controller determines, with the yarn-length measuring mechanism, that the yarn has been unwound from the yarn feeding bobbin up to the position corresponding to the partial defect of the first yarn-defect information, and thus can more accurately determine that the yarn has been unwound from the yarn feeding bobbin up to the position corresponding to the partial defect of the first yarn-defect information. Only the defective portion of the yarn will be discarded.
  • the yarn winding machine may further include a yarn-quality monitoring device configured to monitor a state of the yarn to detect a yarn defect.
  • the controller may manage detection frequency of yarn defects measured by the yarn-quality monitoring device as the yarn information, and when the detection frequency of yarn defects exceeds a predetermined specified frequency, the controller may determine that the yarn has been unwound from the yarn feeding bobbin up to the position corresponding to the partial defect of the first yarn-defect information. In this case, without adding a special device like the yarn-length measuring mechanism, the controller can determine that the yarn has been unwound from the yarn feeding bobbin up to the position corresponding to the partial defect of the first yarn-defect information.
  • this aspect of the present invention can be achieved without an increase in costs.
  • a spinning system is a spinning system including the yarn winding machine described above and a spinning frame.

  • the spinning frame when an uneven twist has been formed in the yarn of the yarn feeding bobbin, the spinning frame may acquire second yarn-defect information on this uneven twist, and when yarn breakage has occurred in the yarn of the yarn feeding bobbin at a frequency equal to or higher than a first frequency, the spinning frame may acquire third yarn-defect information on the yarn breakage at a frequency equal to or higher than the first frequency.
  • the yarn winding machine may determine whether quality of this yarn feeding bobbin satisfies a predetermined quality reference value based on the yarn information acquired when the yarn is wound from the yarn feeding bobbin, and when having determined that the quality reference value is not satisfied, the yarn winding machine may stop winding the yarn from the yarn feeding bobbin. Defect information measured by the spinning frame cannot be checked as accurately as the yarn-quality monitoring device, such as a clearer, provided to the yarn winding machine.
  • the defect information measured by the spinning frame can be verified how accurate the quality of the defect information measured by the spinning frame is by checking the defect information measured by the spinning frame with the yarn quality monitoring device, such as a clearer, which is provided to the yarn winding machine.
