  • the processing section 33 transmits a detection result to a yarn defect comparing section 42 in the machine control device 12. For example, when detecting a yarn defect of which amount of fluff is a predetermined amount or greater than the predetermined amount, the processing section 33 transmits an instruction to a cutter (not illustrated) via the unit control section 50, and cuts the yarn 16.
  • the upper yarn catching member 30 is connected to a negative pressure source and configured capable of rotating around an axis. Accordingly, by rotating in a counterclockwise direction from a position in FIG. 3 , a yarn end of the yarn 16 from the package 18 is acquired, and by rotating in a clockwise direction under this state, the relevant yarn 16 can be introduced into the yarn joining device 26.

  • the comparing section 42 obtains a tendency of occurrence of the entire yarn defect (hereinafter referred to as average yarn defect data) of the automatic winder 10 in accordance with the detection results received from the plurality of the winding units 11. Specifically, by using an average value of a plurality of the detection results or the like, an average value of the degree of the yarn defect (e.g., the degree of the yarn unevenness and the amount of fluff) is calculated. Since the amount of fluff varies by length of the unwound yarn, the average yarn defect data of the yarn defect is preferably obtained in consideration of this respect (see FIG. 5 ). Since the yarn defect varies by quality of the yarn supplying bobbin 15 to be supplied, temperature, humidity, or the like, the average yarn defect data is preferably updated on a moment-to-moment basis.
  • average yarn defect data is preferably updated on a moment-to-moment basis.
  • the yarn supplying bobbin 15 around which the same spinning unit winds the yarn 16 indicates the same quality.
  • the quality is likely to become the same. Therefore, by using an average value of the yarn defect that is calculated for every same spinning unit or every same lot in consideration of the spindle number or the lot information that are read by the RF reader 37, more appropriate average yarn defect data can be obtained as the tendency of occurrence of the yarn defect.
  • the comparing section 42 receives the detection result from each yarn defect detecting device 31 (S101).
  • the comparing section 42 compares a received yarn defect with the average yarn defect data (S102).
  • the comparing section 42 determines by the comparison in step S102 whether or not the received yarn defect indicates a tendency of occurrence different from the average yarn defect data (S103).
  • the comparing section 42 for example, in a case of the amount of fluff, as illustrated in FIG. 5 , when a received amount of the fluff is greater than a predetermined threshold value that is determined by the average yarn defect data (an average amount of the fluff), determination is made that the both indicate different tendencies of occurrence. This method of determination may be changed to a condition that "a value remains the threshold value or greater than the threshold value over a predetermined time".
  • the comparing section 42 When determining that the received yarn defect is located in a range similar to the average yarn defect data (S103), the comparing section 42 does not perform any processing in particular. This is because when the received yarn defect is located in the range similar to the average yarn defect data, the yarn defect is not likely to be caused by the winding unit 11.
  • the comparing section 42 determines whether or not the yarn defect indicates the similar tendency of occurrence even after the yarn supplying bobbin 15 is replaced(that is, whether or not the tendency of occurrence of the yarn defect exceeds the threshold value) (S104).
  • the unit control section 50 discharges the yarn supplying bobbin 15 to resume winding with a new yarn supplying bobbin 15.
  • the comparing section 42 determines whether or not the yarn defect of the new yarn supplying bobbin 15 indicates the tendency of occurrence similar to the tendency of occurrence of the yarn defect of the yarn supplying bobbin before being replaced (S104).
  • the comparing section 42 When the yarn defect having the tendency of occurrence similar to the tendency of occurrence before the replacement is not detected by replacing the yarn supplying bobbin 15, the comparing section 42 notifies to the winding control section 41 that there is a high possibility that the yarn supplying bobbin 15 before the replacement was a defective bobbin (S107).
  • the winding control section 41 that received this notification stores the spindle number of the spinning unit stored in the RF tag 38 of the yarn supplying bobbin 15 before the replacement. Accordingly, in which spinning unit a defective bobbin is likely to generate also can be grasped.
  • the comparing section 42 specifies the relevant yarn defect detecting device 31. The comparing section 42 then determines that the yarn defect is occurring by the winding unit 11 to which the yarn defect detecting device 31 is attached. In a case where the yarn unevenness that is equal to the threshold value or greater than the threshold value is generated before replacing the yarn supplying bobbin 15, and the amount of fluff that is the threshold value or greater than the threshold value is generated after replacing the yarn supplying bobbin 15, since the types of the generated yarn defects are different, the comparing section 42 does not determine that the yarn defect is occurring by the winding unit 11.
  • the comparing section 42 issues an instruction to the unit control section 50 to stop winding the yarn 16 (S105).
  • the comparing section 42 issues an instruction to the unit control section 50 to notify by changing a color of the notifying lamp 51 that the abnormality is occurring in the relevant winding unit 11 (S106).
  • a method of notification is any, and the abnormality may be notified with an alarm sound, or a relevant spindle number and the like of the winding unit 11 may be displayed in a display section of the machine control device 12.
  • the yarn defect caused by the winding unit 11 can be found at an early stage to notify to an operator.
  • the operator upon learning of the abnormality of the winding unit 11 by the notifying lamp 51 or the like, checks a position adjustment of the yarn supplying bobbin 15, and a scratch or the like of the yarn guide 27, and carries out readjustment, replacement of parts, or the like. Accordingly, the yarn defect is prevented from frequently occurring.

  • Each of the plurality of the yarn defect detecting device 31 is mounted in each of the plurality of the winding units 11 and detects the yarn defect of the yarn 16 that is wound by each of the winding units 11.
  • the comparing section 42 compares the detection results of the plurality of the yarn defect detecting devices 31.
  • the winding unit 11 includes the winding section 21 adapted to form the package 18, and the RF reader 37 adapted to read the information for specifying the yarn supplying bobbin 15.
  • the comparing section 42 also calculates the tendency of occurrence of the yarn defect in accordance with the detection results of the plurality of the yarn defect detecting devices 31 and the information for specifying the yarn supplying bobbin 15, which is read by the RF reader 37, and compares the tendency of occurrence and the detection result of the yarn defect detecting device 31.
  • the yarn defect caused by a setting of the entire automatic winder 10 and the yarn defect caused by the winding unit 11 can be differentiated. Furthermore, by including the RF reader 37, even if the yarn defect occurs by the spinning unit, the relevant spinning unit can be specified. Therefore, the occurrence cause of the yarn defect can be more accurately determined.
