Abstract

The invention discloses an automatic edge covering/overlock sewing machine and an automatic edge covering/overlock sewing system. The automatic edge covering/overlock sewing machine comprises a machine frame, a sewing machine, a control system, a platen, a contour recognizing device arranged in front of a feed dog of the sewing machine, and a driving unit arranged beside the feed dog of the sewing machine. The driving unit comprises a servo motor electrically connected with the control system, and a driving wheel connected with a driving shaft of the servo motor. The control system transmits real-time contour information through the contour recognizing device to regulate and control the rotating direction and rotating speed of the driving wheel. The driving wheel drives a workpiece to overcome the friction force between the workpiece and a working table and do linear movements or real-time circumference movements around the real-time curvature center under the common effect of the friction force between the driving wheel and the workpiece and the feed dog of the sewing machine. In the whole edge covering or overlock sewing process, the trajectory adjusting and deviation rectifying can be conducted according to the contour of the workpiece in real time, and the yield and production efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewing equipment, in particular to an automatic hemming / sealing machine and a hemming / sealing system. Background technique [0002] At present, the hemming / sewing of workpieces requires skilled sewing operators. Under the premise that it is difficult to recruit workers, especially skilled sewing workers, various companies have a great demand for labor-saving automatic sewing machines. Existing template sewing machines or pattern sewing machines can only process the sewing lines inside the workpiece, but cannot perform hemming / sealing processing on the outer contour of the cut piece. [0003] Chinese patent "A Visual Positioning Method and System for Sewing", announcement number CN 104005180 B, announcement date 2016.06.22, discloses that the image of the fabric to be sewn is acquired by taking an image of the sewing workbench and processing it. The sewing workbench is preset with Reference point, take th...
