Description

  The present invention relates to a technique for simplifying the configuration of an automatic winder.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2001-159038) has a configuration provided with a shielding plate that stops the flow of suction flow in a connection pipe that connects a suction mouth that sucks and holds a yarn end on the package side and a blower duct. (This document, column 5, lines 19-20).

  By the way, generally, in each yarn winding unit constituting the automatic winder, it is necessary to remove foreign matters attached to the traveling yarn or to capture the yarn end from the package. For this reason, an automatic winder is usually provided with a negative pressure source, and each yarn winding unit includes, for example, a cleaning pipe that sucks and removes foreign matter adhering to the traveling yarn using a negative pressure source. In addition, a suction mouse that sucks and captures the yarn end from the package using a negative pressure source is mounted.

During this winding, the base end 25b of the cleaning pipe 25 is not blocked by the shutter 33 (see also FIG. 4), and therefore foreign matter adhering to the traveling yarn 4 (for example, adhering to the yarn 4). Wax powder, lint, etc.) are sucked and removed by the blower duct 60 when passing near the suction port 25a.

  Next, the unit controller 50 determines whether there is a yarn joining request (S320), and if there is no yarn joining request (S320: NO), the process proceeds to S350. On the other hand, when there is a yarn splicing request (S320: YES), the shielding plate control means 51 rotates the shutter 33, which is in a position to open only the cleaning hole 32a, largely counterclockwise as shown in FIG. Then, an appropriate signal is transmitted to the stepping motor 35 so as to open only the suction hole 32c as shown in FIG. 8 (S330). As a result, the mouse 22 of the upper thread suction catching and guiding means 20 enters the sucking state, and when the unit controller 50 rotates the upper thread suction catching and guiding means 20, the thread end is sucked and caught from the outer periphery of the package 7. The unit controller 50 waits until a signal relating to the completion of yarn joining is received from the yarn joining device 14 (S340: NO), and when the unit controller 50 receives such a signal (S340: YES), the shielding plate control means 51 Transmits an appropriate signal to the stepping motor 35 so that the state shown in FIG. 6 is obtained again, and the unit controller 50 advances the process to S350.

  Incidentally, the unit controller 50 measures the elapsed time from the winding start time using a timer circuit (not shown). If the elapsed time has not reached the predetermined time (S350: NO), the process returns to S310. On the other hand, when the elapsed time has reached the predetermined time (S350: YES), the shielding plate control means 51 is located at the position where the lint hole 32b and the suction hole 32c are closed as shown in FIG. Is rotated counterclockwise, and an appropriate signal is transmitted to the stepping motor 35 so as to open the lint hole 32b in addition to the cleaning hole 32a as shown in FIG. 7 (S360). Thereby, the yarn waste generated in the yarn joining device 14 is sucked and collected by the blower duct 60. Then, after resetting the timer circuit (S370), the unit controller 50 transmits an appropriate signal to the stepping motor 35 so as to be in the state of FIG. 6 again, and the unit controller 50 proceeds to S310. return.
