Abstract

The computerized controller for industrial sewing machine includes operation unit, pedal, speed regulator, control unit, application unit board, power supply board and servo motor. The present invention has mainly DSP chip in the control unit for the software control of servo motor and various sewing program and Hall element-optoelectronic coder combination for the sewing machine needle positioning control. The present invention may be also connected to computer network for remote control and monitoring. The present invention may be used in the control of computerized flat sewing machine, embroidery machine, overseam sewing machine, etc.

Description

technical field [0001] The invention relates to an electronic control device for controlling an industrial sewing machine. Background technique [0002] At present, it involves computer control devices for industrial sewing machines. There have been many literature reports and products at home and abroad. In China, there are "Shanggong", "Standard", "South China", "Zhongjie" and "Feiyue". etc. launch computer-controlled lockstitch sewing machine products; Abroad, such as South Korea Sunstar Company has also developed a series of sewing machines controlled by computers, and Japan's Mitsubishi Electric's "Sewing Machine Control Device" (Chinese Patent Publication No. CN1252110A, published in 2000 May 3) and so on. Combining domestic and foreign literature and products, there is no technology that uses a digital signal processor (hereinafter referred to as DSP), and there is still a problem that the method of modifying the software cannot be used to control computer sewing mac...
