Textile machine

Abstract

With a textile machine including a large number of yarn processing units that produce packages, in spite of an attempt to make the yarn lengths of packages uniform on the basis of a yarn speed detected for each unit by a yarn speed sensor, the yarn length of an actually produced package varies among the units as a result of an inherent error in the yarn speed sensor. The present invention includes a setting member 41 that transmits correction information for each of the yarn speed sensors 7 to the corresponding sequencer 12. Each of the sequencers 12 corrects the detected value from a corresponding one of the yarn speed sensors 7 on the basis of the correction information to calculate a correction value for a corresponding yarn speed to calculate the yarn length of the corresponding winding package 4 on the basis of the correction value for the corresponding yarn speed. The winding units 1 each have a yarn speed sensor 7 that detects a yarn speed, a sequencer 12 that calculates the yarn length of a winding package 4 on the basis of the detected value from the yarn speed sensor 7, and a winding device 20 that forms a winding package 4.

Description

technical field [0001] The present invention relates to a fiber machine provided with a plurality of fiber processing units, the fiber processing unit is equipped with a yarn speed sensor for detecting the yarn speed of a running yarn, and the package formed by the yarn is calculated based on the detection value of the yarn speed sensor. A yarn length calculation device for calculating the length of the yarn, and a winding device for winding the yarn to form a package. Background technique [0002] Conventionally, a textile machine such as a spinning machine or a winder is known that includes a plurality of fiber processing units each of which includes a winding device in order to simultaneously form a package using a plurality of spindles. It is also known that such a textile machine is equipped with a yarn speed sensor for detecting the length of the yarn in the package (Patent Document 1). The length of the yarn can be calculated by multiplying the yarn speed detected by...

Problems solved by technology

[0005] That is, the problem to be solved by the present invention is that, in a fiber machine equipped with a plurality of fiber processing units for producing packages, due to the inherent error of the yarn speed sensor, even if the yarn speed detected by the yarn speed sensor in each spindle is Make the length of the yarn on the package uniform, but the length of the yarn in the actual package is not uniform among all the spindles
