Detection defect removal intelligent control system and control method for yarns of circular weft knitting machine

Abstract

The invention relates to the field of textile machinery, and provides an intelligent detection defect removal device for yarns of a circular weft knitting machine. The intelligent detection defect removal device comprises a rotary worktable, a creel, an electronic yarn clearer for detecting defects of the yarns, a plurality of electromagnetic valves, a PLC (programmable logic controller), a firsttravel mechanism, a second travel mechanism, a yarn splicer, a clamping mechanism, a rotary yarn pulling mechanism, a support, an industrial camera and a dust removal mechanism. The rotary yarn pulling mechanism is arranged on the support, the upper-section yarns at defect positions, which are used as fixed points, of the clamped yarns can be rotationally downwardly pulled by the rotary yarn pulling mechanism, the upper-section yarns and the lower-section yarns at defect positions of the yarns can cross one another by the aid of the rotary yarn pulling mechanism to form crosses, the yarn splicer can slide on the support in the horizontal direction via the second travel mechanism, a yarn splicing opening of the yarn splicer directly faces the crossed yarns which form the crosses, and the yarns can be shorn and spliced by the yarn splicing opening. The intelligent detection defect removal device has the advantage that the problems of incapability of effectively processing yarns with defects detected by existing circular weft knitting machines, time and labor wastage during manual splicing, low production efficiency and influence on the quality of textile fabrics due to factors such as the constant availability of yarn defects and manual connectors can be effectively solved by the aid of the intelligent detection defect removal device.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to an intelligent control system and control method for yarn detection and defect removal of a circular knitting machine. Background technique [0002] In textile production, defects and unevenness often occur, whether it is traditional spinning or various new spinning, even if the best spinning raw materials, the latest spinning equipment and the optimal spinning process are used, yarn defects And unevenness is also unavoidable. Yarn is not only an intermediate product but also a raw material for subsequent processes in the spinning process, so it is particularly important to effectively detect yarn defects in the spinning process. Thick places, fine knots, wrong counts, and chain-like yarn defects are all important factors affecting yarn quality. In the post-processing process, it will not only reduce the production efficiency of the winding machine, but also affect the weaving ...

AI Technical Summary

Problems solved by technology

However, it can only send a signal through the controller to control the alarm to remind the operator to splice the yarn with thick places cut off, which cannot realize automatic processing, low production efficiency, high production cost, and it adopts manual splicing quality Not high while affecting efficiency
