Automatic sewing template sewing processing equipment

Abstract

The invention discloses automatic sewing template sewing equipment and a control system thereof. The automatic sewing template sewing equipment comprises the components of a sewing machine, a template sewing material clamping and drawing mechanism, two upper-layer parallel guiderails, two lower-layer parallel guiderails, and a control system for the automatic sewing template sewing equipment. The automatic sewing template sewing equipment has advantages of realizing sewing of a multilayer sewing material, multiple stitches and multiple layer patterns, improving operation efficiency, realizing relatively low production cost and easy mounting and easy debugging, obtaining easy sewing machine maintenance, and furthermore easily preventing birdnesting in sewing.

Description

technical field [0001] The invention relates to a sewing device, more particularly to an automatic sewing template sewing processing device. 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 the pattern machine has a single fu...

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

These existing CNC template sewing machines store multiple sets of sewing programs in the control system, and the working paths of each set of programs are different. In the sewing process for different die frame patterns, it is necessary to manually call out the corresponding sewing program from the control system. The program needs to be manually adjusted frequently when the pressing mold frames of various patterns are mixed, which has the defects of heavy workload and error-prone

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
