Definitions

  • the present invention relates to a false-twist texturing machine.
  • a false-twist texturing machine processes a yarn supplied from a yarn feeding package in which a raw yarn is wound and manufactures a winding package in which the processed yarn is wound.
  • two yarn feeding packages are installed and a yarn end (tail yarn) of one yarn feeding package is connected to a yarn end (mouth yarn) of the other yarn feeding package. Accordingly, the yarns of two yarn feeding packages are connected to one.
  • the yarn is continuously supplied from the yarn feeding package to the false-twist texturing machine.
  • a knot is formed at a position in which the yarn ends of two yarn feeding packages are connected. For example, in the false-twist texturing machine described in Patent Literature 1 (International Publication WO 2001/83348 ), the switching of the yarn feeding package is detected by detecting the movement of the knot.
  • a yarn splicing operation between the yarn end of one yarn feeding package and the yarn end of the other yarn feeding package is manually performed by an operator.
  • the result of knotting may differ depending on the skill and proficiency of the operator. Then, since the result of knotting affects the properties of the yarn after false-twist texturing when the knot is false-twist textured, the untwisting tension or the like of the false-twist textured knot may become unstable in some cases. Therefore, in general, when the knot is included in the winding package, the quality (grade) of the winding package is set low. However, not all knots affect the quality of the winding package.
  • An object of an aspect of the present invention is to provide a false-twist texturing machine capable of specifying the untwisting tension of the false-twist textured knot.
  • a false-twist texturing machine is a false-twist texturing machine for forming a winding package by performing false-twist texturing on a yarn supplied from a yarn feeding package, the false-twist texturing machine including a tension detection device which detects an untwisting tension of the yarn traveling between the yarn feeding package and the winding package; a switching detection device which detects that the yarn feeding package supplying the yarn has been switched from one yarn feeding package to the other yarn feeding package; and an information processing device which calculates a period of movement time at which a knot of a yarn end of the one yarn feeding package and a yarn end of the other yarn feeding package is expected to move in the tension detection device based on the detection result of the switching detection device and extracts and stores tension a tension data group corresponding to the period of movement time from the detection result of the tension detection device.
  • the information processing device calculates the period of movement time at which the knot is expected to move in the tension detection device and extracts and stores the tension data group corresponding to the period of movement time from the detection result of the tension detection device. Accordingly, it is possible to specify the untwisting tension of the false-twist textured knot.
  • the information processing device may determine that the untwisting tension of the yarn is abnormal when a value of the untwisting tension of the yarn exceeds a threshold value in the detection result of the tension detection device, may extract a tension data group when the abnormality is detected from the detection result of the tension detection device, and may store the tension data group related to the abnormality such that the tension data group related to the abnormality is distinguishable from a data group related to the knot.
  • the information processing device may calculate a reference movement time at which the knot is expected to move in the tension detection device based on the detection result of the tension detection device, may extract a tension data group in a predetermined time range including the reference movement time based on the reference movement time.
  • the period of movement time at which the knot is expected to move in the tension detection device can be calculated based on the reference movement time. Also, since the tension data group of the period of movement time can be confirmed, the data group can be managed with the movement time as a reference.
  • the information processing device may calculate the reference movement time based on a switching time at which the switching detection device detects that the yarn feeding package supplying the yarn is switched from one yarn feeding package to the other yarn feeding package, a traveling speed of the yarn, and a distance of a traveling path of the yarn between the switching detection device and the tension detection device. In this configuration, it is possible to calculate the reference movement time with high accuracy.
  • the information processing device may be provided with an output unit outputting a waveform created based on a tension value and time in the stored tension data group.
  • the waveform is visually confirmed with the output unit, the condition of the false-twist textured knot can be confirmed.
  • the tension data group related to untwisting tension of the false-twist textured knot can be used as an index of quality evaluation Therefore, in the false-twist texturing machine, the quality of the winding package can be evaluated with details.
