Device and method for catching and knotting head yarn and tail yarn of yarn spools

Abstract

The invention discloses a device and method for catching and knotting a head yarn and a tail yarn of yarn spools. The device for catching and knotting the head yarn and the tail yarn of the yarn spools consists of a controller, a binocular vision sensor, a truss robot and other parts; the designed structure is clear, and the reliability is good; the binocular vision sensor is used for capturing the head yarn and tail yarn of A and B yarn spools on the same layer of creel; the image processing, recognition technology and three-dimensional detection method are used for determining the coordinatepositions of the head yarn and tail yarn of the yarn spools; then a yarn capture mechanism is used for accurately capturing the head yarn and tail yarn to be knotted according to the identified positioning information; and the head yarn and tail yarn to be knotted are rotated into a bell mouth of a knotting machine to realize connection, so that the functions of automatic capture, knotting, and continuation are completed.

Description

Technical field: [0001] The invention belongs to the field of textiles, in particular to a device and method for capturing and knotting yarn bobbins and tail yarns Background technique: [0002] Textile is one of the important pillar industries of my country's manufacturing industry. Its intelligent manufacturing is an effective way to realize industrial technology upgrading, change the industrial development model and transform the economic growth mode. However, the intelligent manufacturing of the textile industry is still in its infancy at the practical level at home and abroad. . [0003] Especially in the automatic control system of knitting circular weft machines, when the yarn bobbins on the creel that provide yarns to the circular weft machines are used up, there is no suitable manipulator to replace the manual completion of the thread extension function. The traditional manual method is still used when the machine continues the line, which is low in efficiency and h...

[0002] Textile is one of the important pillar industries of my country's manufacturing industry. Its intelligent manufacturing is an effective way to realize industrial technology upgrading, change the industrial development model and transform the economic growth mode. However, the intelligent manufacturing of the textile industry is still in its infancy at the practical level at home and abroad.

[0003] Especially in the automatic control system of knitting circular weft machines, when the yarn bobbins on the creel that provide yarn to the circular weft machines are used up, there is no suitable manipulator to replace the manual completion of the thread extension function, resulting in the replacement of the yarn bobbins for the circular weft knitting machines at present. The traditional manual method is still used when the machine continues the line, which is low in efficiency and high in labor costs, and it is impossible to truly realize the intelligent manufacturing of the production line
