Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0035] Such as figure 1 As shown in the present invention, a device for detecting and removing weak rings of yarn strength includes a capacitive sensor for obtaining a signal of uneven thickness of the yarn passing through a capacitive sensor test slot, and a photoelectric sensor for obtaining yarn The uneven diameter signal D of the thread passing through the photoelectric sensor test groove; the CPU, including the first processing unit, calculates the number of fibers in the yarn section Tn according to the linear relationship between the number of fibers in the yarn section Tn and the yarn linear density M; The second processing unit, according to the formula Calculate the yarn density ρ value; the judging unit judges whether the density p value is lower than the p value threshold v...

Abstract

The invention discloses a yarn strength weak ring detection and elimination method and apparatus. The apparatus is formed by a capacitance type sensor, a photoelectric sensor and a plurality of processing units; Yarns pass through the capacitance type sensor and the photoelectric sensor at the same time; signals of uneven yarn thickness and uneven diameter signals are sent to related processing units; uneven thickness signals of yarns are output by the capacitance type sensor after the yarns passing through the sensor are sent to the processing unit and cross section yarn numbers (Tn) can be calculated via uneven yarn density; wand hen a certain yarn is Tn and lower than a certain value and a Rho value is lower than a threshold value, the yarn section possesses a strong weak ring. The invention provides a yarn weak ring online detection method and apparatus; and the weak ring can be eliminated as needed; yarn break and machine stop due to yarn strength weak ring can be reduced; and production efficiency and economic benefits can be improved.

Description

【Technical field】 [0001] The invention relates to the winding process of yarn production in the spinning industry and the quality inspection of yarn products, in particular to a method and device for detecting and removing strong and weak links of yarn. 【Background technique】 [0002] During the yarn production process, due to process defects, equipment failure and environmental factors, the strength of some yarns is reduced and the tensile resistance is reduced. The use of this yarn in subsequent processes (warping, sizing and weaving) will cause end breaks, seriously affecting production efficiency and benefits. Currently, there is no efficient way to measure yarn strength weak spots. In the yarn laboratory, the average breaking strength of the yarn is measured with a single yarn strength meter. Average breaking strength does not reflect yarn strength weak spots. Due to the small number of test samples, the probability of being able to detect weak spots in the yarn is v...
