Problems solved by technology

[0009] And because the single-spindle-driven multi-twisting machine is equipped with a spindle drive motor on each spindle, when multiple winding units are arranged side by side, sometimes the voltage drop problem of the power supply bus is caused, so that the rotary drive of each spindle It cannot be carried out stably, and there is a problem of unstable twisting

Embodiment Construction

[0044] Next, a first embodiment of the present invention will be described with reference to FIGS. 1-4. The single-spindle-driven multi-twister 1 is configured by arranging yarn winding units U of 80 to 308 spindles in parallel, as shown in FIG. 1 . The one-spindle yarn winding unit U is provided with a spindle device 2 and a winding device 3 connected thereto above it, and winds a single yarn supply package 8 onto a take-up package P.

[0045] The above-mentioned spindle device 2 is provided with a silk feeding package 8, a stationary disc 31, a tensioning device 32, a rotating disk 33 and a spindle drive motor 6, which twists the yarn Y by the spindle drive motor 6. A DC brushless motor BLM is used as the spindle drive motor 6, and a rotary disk 33 is provided on its output shaft. And on the rotary disc 33 is provided with a stationary disc 31, on which a silk feeding package 8 can be placed. A tensioning device 32 is also arranged on the top of the silk feeding package 8,...

Abstract

This invention provides an apparatus for treating power failure capable of decelerating and stopping spindle driving system motors and drum driving system motors while synchonizing both with simple control at the time of the power failure. This apparatus for treating power failure of a multiple twister drives the plural spindle driving motors installed for each spindle and the winding drum driving motors common to the plural spindles with inverters, respectively. The apparatus is equipped with a power failure detecting means for detecting the power failure when the voltage is reduced by a prescribed value or above, stop commanding means for outputting stop commands to respective inverters when detecting the power failure and the stopping means for performing feedback control so as to stop each of motors at a predetermined stopping time based on the stop commands.

Description

[0001] This application is a divisional application of the invention application with the filing date of March 12, 1999, the application number of 99103676.X, and the invention name of "single-spindle-driven fiber machinery". technical field [0002] The present invention relates to a single-spindle-driven textile machine, which is constructed by arranging a plurality of spindles side by side, each spindle is provided with a spindle driving motor, and the driving motors are driven by a rotation speed control device to be controlled. Background technique [0003] As shown in Figure 13, the previous multiple twisting machine is provided with a plurality of multiple twisting units, wherein the multiple twisting units have a spindle device 301a and a take-up device 301b, and each multiple twisting unit is provided with a driving mechanism 310, It drives the take-up drum 306 and the traversing wire mover 307 and the spindle 303. The spindle unit 301a transmits the driving force o...
