Overedger control system and method, and overedger

Abstract

The invention provides an overedger control system and method, and an overedger. The overedger control system comprises the overedger used for carrying out a sewing operation, a material feeding mechanism used for conveying cloth materials, and a master control module, wherein the master control module is used for the movement of the material feeding mechanism relative to X and Y directions of theoveredger and / or rotation of the material feeding mechanism relative to a Z axis of the overedger, wherein X, Y and Z directions are mutually vertical, the X and Y directions are in parallel with aplane where the cloth materials are positioned, and the Z direction is vertical to the plane where the cloth materials are positioned. The overedger control system and method, and the overedger have high production efficiency and processing accuracy.

Description

technical field [0001] The invention relates to the technical field of sewing equipment, in particular to an overlock sewing machine control system, a control method and an overlock sewing machine. Background technique [0002] The overlock sewing machine is commonly known as overlock machine, side car, and overlock machine. The main function is to prevent the seam of the garment from fluffing. It can not only be used for hemming, but also can be used for sewing T-shirts, sportswear underwear, knitting and other fabrics. Hemming is in progress. With the increase of labor costs, how to improve work efficiency and reduce errors caused by manual operation has become the goal pursued by various processing enterprises, and it is also the strong desire of towel and square towel processing industry. [0003] To complete the processing of a towel, rag or square, generally speaking, the four sides need to be sewn, and in most cases, the corners need to be processed into rounded corn...

AI Technical Summary

Problems solved by technology

However, an ordinary overlock sewing machine can only sew straight lines, and cannot perform automatic corner sewing or rounded corner sewing of any radian. At present, the processing factory basically uses an overlock sewing machine operated by skilled workers, and corners can be rotated according to requirements. Manual operation drives towels, squares, etc. to corner

[0004] At present, for the hemming, when it is necessary to sew multiple edges continuously and the sewing at the corner is required, it is completely manually intervened, and the human hand controls the corner movement of the towel, square scarf, etc. according to the current sewing speed, so the whole The processing has the following disadvantages: when the processing requirements are relatively high, due to the high sewing speed of the overlock sewing machine (above 3000rpm), in order to ensure the processing quality, it is necessary to slow down the sewing at the corner in order to better complete the corner action. , which greatly reduces the production efficiency; and because the corner is completely realized by manual intervention, the consistency of the corner cannot be guaranteed, and the rate of defective products is high
