Title:
YARN WINDING MACHINE AND TEACHING METHOD
Document Type and Number:
Japanese Patent JP2022177371
Kind Code:
A
Abstract:
To provide a yarn winding machine in which accuracy of a position where a working truck is stopped is less likely to be reduced and further which can adjust the position where the working truck is stopped.SOLUTION: An automatic winder comprises a plurality of yarn processing units, a doffing truck 40, a stop position identifier 70, an optical sensor 47, and a control part. The doffing truck 40 travels along a traveling direction, where a direction in which the yarn processing units are arranged is the traveling direction, and performs an operation with respect to the yarn processing units. The stop position identifier 70 is provided at a position corresponding to a stop position of the doffing truck 40. The optical sensor 47 is provided on the doffing truck 40 to detect the stop position identifier 70. The control part, based on the detection amount detected by the optical sensor 47 for the target stop position identifier 70 at which the doffing truck 40 is stopped or light receiving position, calculates the position of the doffing truck 40 with respect to the stop position identifier 70, to control the doffing truck 40 so as to stop at the predetermined stop position of the doffing truck 40.SELECTED DRAWING: Figure 5
