Definitions

  • the present invention relates to a yarn defect detecting device and a winding device.
  • a textile machine such as a yarn winding device is provided with a yarn defect detection device that detects a defect included in a yarn (yarn defect) and removes the yarn (see, e.g., JP 4436938 ).
  • a method described in JP 4436938 monitors a traveling yarn and, when detecting a defect of the yarn, cuts the yarn at a downstream side of the detected yarn defect to interrupt a winding process. In this method, the yarn is removed by a predetermined length.
  • DE 19640184 describes a method for removing both long and short yarn defects at the winding heads of a bobbing winding machine. Following the appearance of a yarn defect, the length of the defective yarn between the time of the appearance of the defect and the time of a subsequent yarn cut is determined. A suction tube is positioned in front of the winding bobbin to aspirate the defective yarn therefrom. The yarn is unwound, the entry of the yarn into the suction tube is determined by means of a sensor disposed therein, and the yarn length unwound from the winding bobbin and entering the suction tube is determined.
  • the unwinding process is stopped at the time when, on the basis of the detected length of defective yarn, a sufficient yarn length has been aspirated into the suction tube so that, upon subsequent insertion of the yarn from the winding bobbin into the yarn end connecting device, the yarn length wound since the appearance of a yarn defect remains outside of the yarn end connecting device for the purpose of being cut and discarded.
  • EP 1 238 937 describes a process to remove spinning faults from textile yarn.
  • the faults are detected by a sensor and cut out, the good ends being spliced.
  • the initial sequence of faulty material is not immediately cut out, but accumulated and then cut out in a single length.
  • a yarn cleaning assembly with a sensor head, a cutting and splice unit with a control unit, and several yarn cleaning stations.
  • the faulty yarn section is removed at once.
  • the faulty yarn is not immediately removed. If a cluster of faults is detected, operation of the two stations is synchronized to form a single operation.
  • the system activates the cutting operation using the number of faults detected per unit length of the yarn.
  • DE 43 35 262 A1 describes a yarn defect detecting device comprising a yarn defect determining section including a type determining section, and an end point identifying section.
  • the yarn is removed by a predetermined length, so that if a length of the defect is larger than the predetermined length, the removal process needs to be repeated several times. This deteriorates production efficiency. That is, the repetitive execution of the removal process increases the number of yarn joining points, resulting in deterioration in quality of a yarn product (e.g., yarn package).
  • a yarn product e.g., yarn package
  • An object of the present invention is to provide a yarn defect detecting device and a winding device capable of detecting a plurality of yarn defects each having a length equal to or larger than a reference length collectively as one defect.
  • a yarn defect detecting device of the present invention is defined in claim 1.
  • Preferred embodiments are defined in the dependent claims.
  • the yarn defect detecting device may further include a yarn cutting section that cuts the yarn when the end point identifying section identifies the longitudinal direction end point of the defect.
  • the yarn defect detecting device when a part of the yarn having a thickness falling outside a thickness threshold specified as a determination threshold has a length equal to or larger than a reference length specified as the determination threshold, an end point of a defect in a longitudinal direction is identified.
  • a length of the yarn to be removed can be determined based on the length of the part of the yarn having the thickness falling outside the thickness threshold specified as the determination threshold, thereby eliminating the need to perform a plurality of times of removal operations as done in the conventional approach. This allows improvement in production efficiency and prevention of quality deterioration.
  • a required quality level is high, it can be estimated that the length of the defect to be detected is larger. It is possible to detect a plurality of defects collectively as one long defect, thereby allowing achievement of a high quality yarn product.
  • the yarn defect detecting device may include a measuring section that measures the length of the defect. Measuring the length of the defect allows collective detection of a long defect, thereby allowing achievement of a high quality yarn product.
  • the yarn defect determining section may determine an occurrence of the defect based on a first detection condition, and the end point identifying section may determine the end point of the defect based on a second detection condition different from the first detection condition.
  • detection of the defect can be detected by determining presence/absence of the defect based on the first detection condition, and the end point of the defect can be detected based on the second detection condition. For example, setting the second detection condition that is stricter than the first condition results in measurement of longer defect, thereby ensuring margin of detection error.
  • the yarn defect determining section includes a type determining section that determines a type of the yarn defect, and the end point identifying section determines whether to identify the end point of the defect depending on the defect type.
  • the yarn defect type includes "Nep", “Slub”, “Thick place”, “Thin place”, and the like.
  • the defect such as “Nep” or “Slub” is comparatively small in length and is thus removed without measurement of the length of the defect.
  • the defect such as “Thick place” or “Thin place” may be generated by unevenness of a sliver as a material during fine spinning and may thus be large in length. The length of the defect is measured only for the defect comparatively large in length and whereby defect removal corresponding to the defect length can be performed.
  • the measuring section may include a normal length measuring section that measures a length of a normal part of the yarn having a thickness falling within the thickness threshold specified as the determination threshold.
  • the end point identifying section may identify, when the length of the normal part following the part of the yarn determined by the yarn defect determining section as the defect is equal to or larger than a predetermined length, the end point of the defect.
  • the measuring section may measure the lengths of the two defect parts and normal part as one continuous defect.
  • the length of the normal part following the defect is short, it is possible to collectively measure a plurality of defects as one continuous defect. This reduces the number of times of removal of the defect, allowing improvement in production efficiency and product quality.
  • the yarn defect detecting device may further include a control section that controls removal of the defect. After the measuring section measures the length of the defect, the control section may instruct removal of a yarn by a length equal to or larger than that of the measured defect.
