A Method for Controlling Sewing and Edge Trimming of Pattern Machine with Rotary Cutter Head

Abstract

A method of controlling the sewing and edge trimming of a pattern machine with a rotary cutter head. After setting the movement speed of a needle spindle in advance, the XY axis movement speed of the feeding frame, the left and right rotation speed of the cutter, and the up and down cutting movement of the cutter are calculated by formulas. Speed, and use it to control the five axes of the pattern machine to realize sewing and trimming. The present invention analyzes the relationship between the movement speed of the needle spindle and the XY axis movement speed of the feeding frame, the speed of the needle spindle, the movement amount of the feeding frame, the left and right movement speed of the rotary cutter, the speed of the needle spindle and the up and down cutting speed of the rotary cutter , established a speed calculation method for five-axis cooperative control, and based on this calculation method, proposed a control method for sewing and trimming the pattern machine with a rotary cutter head, so that the pattern machine with a rotary cutter head can realize accurate sewing at the same time Nice cut edge effect.

Description

technical field [0001] The invention relates to the technical field of sewing equipment control, in particular to a method for controlling sewing and trimming of a pattern machine with a rotary cutter head. Background technique [0002] The rotary cutter head cutting pattern machine is an intelligent sewing equipment used in the processing of small parts in clothing, bags and other industries. In the garment industry, small parts such as pocket flaps, trouser waist extensions, cuffs, collars, drawstrings, etc. need precise trimming while sewing. This pattern machine can well adapt to the production needs of this type of parts. Trimming is achieved during sewing. This sewing and edge trimming function requires the coordinated control of five axes: the main shaft that controls the needle, the XY axis that controls the movement of the feeding frame, and the UZ axis that controls the up and down cutting and left and right rotation of the cutter. A complete sewing process is as...

AI Technical Summary

Problems solved by technology

[0005] The above two methods only realize the three-axis control of the needle spindle and the XY axis of the feeding frame, which can realize the sewing of materials. They are only suitable for the control of pattern machines that only carry out material sewing, and cannot be applied to realize sewing and edge trimming. Control of Rotary Cutter Head Pattern Machine

At present, there is no proprietary system for controlling this kind of machinery in China, so it is necessary to research and develop this technology, which will also bring great help to the development of such special machinery in China
