Embodiment Construction

[0060] Embodiments of the present invention will be described below with reference to an example for false twist processing.

[0061] First, a schematic configuration of a false twist processing machine will be described with reference to FIG. 1 .

[0062] In each spindle in the false twist processing machine 1, the yarn Y unwound from the yarn supplying package 16 is fed by the first feeding roller 11 and the second feeding roller 12 arranged on the downstream side of the first feeding roller 11. stretch.

[0063] Here, the yarn Y includes not only yarns made of thermoplastic synthetic fibers such as polyester and polyamide, but also other yarn members.

[0064] Between these first and second feeding rollers 11 and 12, from the upstream side, a heater 3 for heat setting, a cooling plate 4, and a nipper type twister 5 as a false twisting device are arranged in sequence. The device 3 heats the twisted yarn Y to the stretching temperature, and the cooling plate 4 cools the yar...

Abstract

To solve the problem of a textile machine having a plurality of spindles being started / stopped individually that noise due to belt driving is significant when the drivers of respective spindles are operated synchronously using a timing belt and efficiency lowers due to energy loss, and that when an arrangement for operating respective drivers synchronously by controlling each of a plurality of inverters connected with one converter is employed, the arrangement is complicated because each drive motor is controlled by an inverter at all times and a software control performing synchronous operation control of respective spindles is required. Drive source of each spindle comprises a synchronous induction motor 53, 54,... connected in parallel with at least one inverter power supply 21.

Description

technical field [0001] The present invention relates to a drive device for a textile machine which has a plurality of spindles and starts and stops each spindle. Background technique [0002] In a textile machine having a plurality of spindles, it is required that the quality of the yarn produced or processed with each spindle be uniform for all the spindles. For example, in a false-twisting processing machine equipped with a false-twisting device for false-twisting a yarn, and a false-twisting processing machine for false-twisting the yarn, twist unevenness cannot be generated in the yarn processed by each spindle. As the false twisting device, when a false twisting processing machine equipped with a belt type false twisting device called a nipper type twister, in which two endless belts are intersected in a cross shape, is described as an example, No twist unevenness occurs in the processing machine, there must be no deviation in the rotational speed of the endless belt b...
