Automatic sewing anti-nest template sewing device and control system

Abstract

The invention discloses an automatic sewing anti-nest template sewing device and a control system thereof. The automatic sewing anti-nest template sewing device comprises a sewing machine, a template sewing material clamping and dragging mechanism, two upper parallel guide rails, two lower parallel guide rails and a control system of the automatic sewing anti-nest template sewing device. The automatic sewing anti-nest template sewing device can be used for sewing multilayer sewing material, a plurality of stitches and a plurality of patterns, the work efficiency can be raised. The automatic sewing anti-nest template sewing device is low in production cost and easy to mount and debug, the sewing machine is easy to maintain, and a sewed nest can be easily avoided.

Description

technical field [0001] The invention relates to a sewing device, more particularly to an automatic sewing anti-bird's nest template sewing device and a control system thereof. Background technique [0002] At present, in clothing, leather bags, leather shoes manufacturing enterprises, when sewing parts, they basically use a single-function lockstitch sewing machine to sew clothing parts by hand. Due to the manual sewing stitches, the operator's eyes, hands, and feet must be highly coordinated. , requires a higher technical level of the operator, and it is necessary to send additional technical staff to draw assembly marks for the subsequent process, especially for some high-quality high-end clothing, leather goods, bags, and leather shoes. The technical level of the staff is higher, and the labor intensity is high, the production efficiency is low, the stitches sewn by hand are not straight, the needle pitch is uneven, and other defects cause the yield rate to be low, while ...

AI Technical Summary

Problems solved by technology

However, these existing CNC template sewing machines often have problems such as fleece when sewing multi-layer sewing materials such as down jackets

These existing CNC template sewing machines also have the problem of origin positioning deviation when replacing different sewing templates

These existing CNC template sewing machines also have the problem of close contact between the sewing template and the plane of the sewing machine table, resulting in very large friction, which is not conducive to the rapid plane movement of the sewing template

These existing numerical control template sewing machines have the disadvantages of low sewing speed, slow moving speed of empty seam templates and poor stability and reliability due to the structural limitations of the moving devices used in them. At the same time, the sewing templates of these existing numerical control template sewing machines The clamping driving device is relatively complicated, and the metal components of the sewing template clamping driving device of these existing numerical control template sewing machines are all fixed between the head and the machine base of the sewing machine, resulting in the failure of these existing numerical control template sewing machines. The production cost is high, the installation and debugging are not only complicated but also require high technical personnel, and the maintenance of the sewing machine is difficult

The actual sewing stitches of these existing CNC template sewing machines are directly converted by software. When there are cumulative cutting errors in the different slotting tracks of the sewing templates, the actual sewing stitches of the CNC template sewing machines do not match the slotting tracks of the template and manual labor is required. The defect of cumbersome modification and adjustment

Moreover, these numerical control template sewing machines all face a problem, that is, after each sewing stitch is automatically sewn and the bottom surface thread is automatically cut, the upper thread will be in a free state, causing the upper thread of the next stitch to be in the sewing piece There are too long thread ends or piles of threads below, resulting in the sewing bird's nest phenomenon
