Control device of a transversing gear

Abstract

The invention relates to a control device of a transversing gear capable of eliminating the axial nonuniformity of the package density. A transversing control part (80) of the transversing gear (34) comprises a position-speed mode generation part (60) for supplying the relation between the position of a yarn guide (33) and the walking speed of the yarn guide (33) at the position, namely position-speed mode; an object speed calculation part (61) for calculating the object walking speed of the yarn guide (33) based on the position-speed mode supplied by the position-speed mode generation part (60) and the current position of the yarn guide (33) detected by a coder (49); and a drive control unit for controlling the action of a drive unit of the yarn guide based on the walking speed calculated by the object speed calculation part (61).

Description

technical field [0001] The invention relates to a control device for a traversing device for traversing a yarn. Background technique [0002] As such a technique, Patent Document 1 discloses a method capable of controlling an accurate position of a yarn guide of a traverse device. Specifically, the current position of the yarn guide is monitored and compared with a predetermined target position, and the running speed of the yarn guide is adjusted to eliminate the deviation. Please refer to Claim 1, Claim 2, paragraph numbers 0005, 0009 and 0011 of Patent Document 1 if necessary. [0003] [Patent Document 1] Japanese Patent No. 4155705 [0004] The control block diagram of the control device (hereinafter referred to as B control device) of the traverse device disclosed in the above document 1 is as follows: figure 1 (a) You reproduced it like that, please refer to it. [0005] like figure 1 As shown in (a), the B control device is mainly composed of a time-position patte...

Problems solved by technology

[0006] However, since the above-mentioned B control device gives priority to the current position of the yarn carrier over the running speed of the yarn carrier, in order to make the current position of the yarn carrier consistent with the desired one, the running speed of the yarn carrier fluctuates up and down, which causes production problems. The non-uniformity of the package density in the axial direction

More specifically, in the case of using the above-mentioned B control device, if the fluctuation of the running speed of the yarn carrier occurs irregularly and randomly to a certain extent, the unevenness of the density of the package in the axial direction may almost cancel out.

However, in fact, from the fact that the inventors of the present application have experimentally implemented the above-mentioned B control device, it has been confirmed that the fluctuation of the running speed of the yarn carrier always occurs in the same way, and it has not been eliminated so far. The regularity
