Sewing method for intelligently and adaptively adjusting sewing patterns

Abstract

The invention discloses a sewing method for intelligently and adaptively adjusting sewing patterns. The sewing method involves a sewing machine head, a sewing control system, a workbench, an automaticconveying mechanism, a displayer, an input unit, a data acquiring unit and a processing unit, and the displayer, the input unit, the data acquiring unit and the processing unit are connected with thesewing control system. The sewing method comprises the following steps that after the data acquiring unit acquires the sewing data of a material to be detected, the sewing data are sent to the a memorizer of the sewing control system; the processing unit recognizes and obtains the contour information of the material and automatically generates sewing patterns, or the sewing patterns and pattern sewing stitches in a database are recognized and compared, coordinate conversion is carried out, and the coordinates are stored in a coordinate calculating module; a stitch setting module calls an image coordinate calculating module to convert set line patterns into sewing position coordinates; and then the sewing machine head is controlled to carry out sewing according to the set line patterns. The contour information of the material to be sewn is automatically recognized, and the work efficiency is improved.

Description

【Technical field】 [0001] The invention relates to sewing technology, in particular to a sewing method for intelligent self-adaptive adjustment of sewing patterns. 【Background technique】 [0002] With the rapid development of industrial automation technology, it is a trend to replace manual sewing with automatic sewing in the sewing equipment industry. For automatic sewing, the application of machine vision technology is a key point. The machine vision technology applied in automatic sewing equipment is mainly to place the pattern material on the target area of ​​the material board, use the camera to collect its pictures and obtain the pattern through image processing technology Material information, and after processing it, plan subsequent sewing actions. [0003] However, in the existing sewing machine, in the sewing process, for pattern materials of different sizes or equal proportions, the trajectory line preparation is complicated and cumbersome. It is necessary to comp...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing sewing machine, in the sewing process, for pattern materials of different sizes or equal proportions, the trajectory line preparation is complicated and cumbersome. It is necessary to compile patterns on professional pattern-making software, and then input the prepared patterns into the sewing machine. embedded system

The sewing size of the compiled pattern is fixed and cannot be adjusted according to the actual situation of the sewing material

If you need to change other patterns, you need to re-program the pattern in the pattern-making software. The cycle of pattern adjustment is long, it is difficult to learn and use, and the operation is inconvenient, which affects production efficiency.

This results in that existing sewing machines cannot automatically generate sewing lines and sewing machine trajectory lines according to the actual needs of the products to be sewn; Manually adjust the products one by one or batch by batch according to the actual needs of the products. Due to the slow speed and insufficient accuracy of manual inspection, it not only wastes production time and human resources, but also reduces the production efficiency of the entire production line.

[0004] Especially in the sewing process of bra materials, in the sewing of bra back buttons, it is necessary to pre-position and tighten the back buttons. If manual operation is used, the efficiency is relatively low, and there are safety hazards. At the same time, different bras correspond to different sizes. Or type, which requires high automation precision, it is difficult for general pattern sewing machines to meet this requirement
