Problems solved by technology

[0016] On the other hand, in a single-spindle drive type twister that needs to decelerate and stop the spindle shaft and drum in a short time, since the winding amount of the yarn from the start of deceleration to the stop is small, the winding caused by the lag angle The influence of the change of the yarn length on the number of twists increases, and there is a problem that the accuracy of the number of twists of the twisted yarn deteriorates

Abstract

The controlling device of the yarn twister is provided with a spindle apparatus 1, a spindle-driving motor 10, a spindle changer, a winding motor, a slowdown and stop controlling means 74 for the spindle driving motor, and a slowdown and stop controlling means 73 for a drum driving motor. The delay angle of the spindle apparatus 1 is included in the parameters for setting the slowdown and stop rate of the spindle driving motor 10 or the drum driving motor 20 controlled by the slowdown and stop controlling means 74 for the spindle driving motor or the slowdown and stop controlling means 73 for the drum driving motor.

Description

technical field [0001] The present invention relates to a control device for a twisting (yarn) machine, and more particularly to a technique for controlling the degree of deceleration and stop of a spindle (spindle) driving motor or a winding motor. Background technique [0002] In the prior art, twisters are known for twisting yarns unwound from yarn feed packages. Most of them are simultaneous drive type twisters configured by winding one drive belt around each of a plurality of parallel spindle shafts, and simultaneously driving a plurality of spindle shafts with one drive motor using the drive belt. In such a twisting machine, the drive of the drum of the winding device for winding the yarn unwound from the yarn feeding package is transmitted from the spindle shaft driving motor through the transmission device. [0003] On the other hand, in recent years, in order to reduce the noise and power loss when driving, drive motors are respectively provided on each spindle dev...
