Description

Technical Field

[0001] This invention relates to the field of sewing and binding processing technology, specifically to an automated sewing equipment and its processing method. Background Technology

[0002] In daily life, some items are essential, such as square scarves, clothes, shoes, and hats. These items require materials like fabric, organic materials, and cotton, and often need to be cut to size for use. However, these cut items often have rough edges. Over time, these rough edges can cause material to fall off, fray, or even injure the user. Therefore, removing these rough edges is crucial. Traditionally, rough edges are removed by manually sewing the edges of the materials, which is time-consuming, labor-intensive, and inefficient. While using a sewing machine frees up manual labor, it only sews on one side, resulting in low efficiency and asymmetry, affecting the overall aesthetics and usability. Furthermore, in traditional sewing processes, the sewing machine head is usually fixed to a stand; if a malfunction or thread failure occurs, operation becomes time-consuming and labor-intensive, significantly increasing the completion time.

[0003] Currently, there are still some overlock sewing equipment on the market with relatively complex processing technology. They require overlocking the edges of unrelated materials, which wastes raw materials (binding strips and sewing thread, etc.), lengthens processing time, and reduces production efficiency. For example, the two patents with patent numbers CN210561117U and CN214005001U have relatively complex processing equipment, which adds 360° rotation and heaters, etc., to sew the fabric around the four sides. Moreover, they use a single machine head, which is inefficient and has high production costs. When the fabric rotates, it will be misaligned, which will also greatly affect the sewing effect around the whole circle.

[0004] Therefore, by leveraging technological advancements and promptly introducing intelligent and automated processes, the production volume of knitted goods has increased, and processing speed has accelerated. This has solved processing challenges for some raw knitted materials: trimming is often required before knitting, which involves multiple steps, resulting in low efficiency, high time and labor costs, and often leaving burrs on the edges of the trimmed material, affecting usability and aesthetics. Furthermore, some similar knitted items, after being cut to the desired shape, often have rough edges, requiring trimming and sewing. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of slow processing, time-consuming and labor-intensive material binding, incomplete binding, missing burrs, uneven cutting, and material waste caused by existing methods. By designing the material binding and sewing process, the process is simplified. Since the material is generally square, sewing opposite edges protects them from wear and prevents burrs. Users are accustomed to using the bound edges for handling, thus reducing wear on other parts. The invention utilizes a support bracket, feeder, cutting mechanism, sewing mechanism, and carrier to achieve automation. The robotic arm can perform tasks such as trimming, binding, and sewing labels onto materials. It can also perform flexible gripping and fine-tuning, select and remove waste materials, and achieve rapid and even cutting to prevent material deviation during transport. Furthermore, it allows for flexible maintenance of components, especially the sliding and rotating parts of the sewing machine, facilitating quick repairs. By analyzing the weave of the warp and weft threads, it can identify materials with easily worn or frayed warp threads and weft threads, enabling unidirectional binding to save materials, avoid waste, and achieve high-efficiency production.

Then, the binding strip, the label strip and the edge of the material are sewn together to complete the binding of the material. Under the conveyor, the binding material will be conveyed to the transfer table. The gripper will grab the binding material and put it on the carrying platform. The carrying platform will gradually descend as the binding material is stacked layer by layer.

[0060] Step 8: After the edge-binding material has been processed, pull the sewing machine to pull it out of the processing position.

[0061] Beneficial effects

[0062] This invention simplifies the edging process of materials through its sewing design. Materials are typically square; sewing opposite edges protects them from wear and prevents burrs. Users are accustomed to handling materials with the edged edges, reducing wear on other parts. Utilizing a support frame, feeder, cutting mechanism, sewing mechanism, and carrier, the invention automates material cutting, edging, and label sewing. It features a robotic arm with flexible gripping and fine-tuning capabilities, allowing for waste material selection and removal, rapid and even cutting, and preventing material deviation during transport. It also enables flexible maintenance of components, especially the sliding and rotating parts of the sewing machine, facilitating quick repairs. By considering the warp and weft weave of the material, some materials have easily worn or frayed warp threads, while others have easily worn or frayed weft threads. Unidirectional edging saves material, avoids waste, and achieves high-efficiency production. This edging equipment can be widely used for edging various materials (such as knitwear, cotton, and linen). Attached Figure Description
