Description

Technical Field

[0001] The invention relates to an automatic sewing system for knitted clothing pieces, belonging to the technical field of textile clothing equipment. Background Art

[0002] Knitted clothes are highly elastic, wrinkle-free, breathable, soft and comfortable to wear. They can be used as both business attire and casual wear. They are deeply loved and welcomed by consumers and have large market sales.

[0003] However, knitted clothes are very difficult to process due to the softness, variability and curling of the fabric itself. It is difficult for workers to take the pieces of knitted clothes during sewing, and the pieces are seriously deformed during the process. The edges of the pieces are seriously curled, which makes sewing production very difficult, the production efficiency is extremely low, and it is very easy to cause the size of the sewn clothes to be unstable, which seriously affects the quality of knitted clothes.

[0004] Knitted garment pieces generally include lapels, bottom collars, sleeve pieces, front pieces and back pieces. It is a manual sewing method that requires multiple sewing processes to complete the sewing of clothes. During the sewing process, multiple groups of workers are required to pass on and cooperate with each other, and the sewing process is completed by workers operating the sewing machine. After sewing, the pieces are formed. At present, the knitted assembly line sewing clothes on the market generally includes four main actions for a single process and a single person: passing pieces, taking pieces, sewing pieces, and putting down pieces. Among these four main actions, sewing pieces is an indispensable action, which is completed by sewing machines, and it is also the only action in these four processes that can generate value. However, passing pieces, taking pieces and putting down pieces are so far indispensable and redundant actions. These three actions will not generate value, which is a waste of actions and affects production efficiency. However, the current production method cannot complete the sewing work without these three actions. Therefore, this manual sewing method is particularly time-consuming and labor-intensive, and the production efficiency is extremely low.

[0005] With the progress of the market, assembly line operation has begun to appear. Each person is responsible for sewing a single piece. After sewing multiple groups of pieces, they are transported to each workstation through automatic conveying for coordinated work. However, this method eliminates the manual transfer of clothing pieces through automatic conveying, which improves the production efficiency to a certain extent, but still requires a large number of people to perform manual operations. The two redundant actions of picking up and putting down clothing pieces still exist, making the production efficiency still low. Especially in the process of picking up clothing pieces, the serious deformation and curling of clothing pieces have not been solved. With the increase of the number of picking and putting, the deformation of clothing pieces and the curling of edges will become more and more serious, and the unstable size of knitted garments will become more and more serious. In addition, operators are still required to perform manual sewing processing through sewing machines. Workers have to do repetitive work and have high labor intensity. The production quality will vary from person to person, and it is seriously affected by subjective factors, and the quality is not stable enough.

[0006] The name of the Chinese invention patent is "A single-piece flow production line control system" and the application number is "CN201711174306.9". This patent discloses a single-piece flow production line control system. This line control system automatically transports clothing pieces to the sewing station, eliminating the redundant and value-free action of transferring clothing pieces. However, the two redundant and value-free actions of picking up and putting down clothing pieces still exist, and more importantly, the workers still have to perform manual sewing operations. Summary of the invention

[0007] The purpose of the present invention is to overcome the above-mentioned defects of the existing manual sewing of knitted clothing pieces, and propose an automatic sewing system for knitted clothing pieces, which realizes a fully automatic sewing system for automatic sewing of clothing pieces by automatically feeding multiple groups of pieces and directly transmitting the pieces to the sewing machine, thereby improving the production efficiency of knitted clothing, improving the product quality of knitted clothing, and reducing the difficulty of knitting clothing operation and the labor intensity of workers.
