The present invention belongs to the technical field of roller sewing, and specifically discloses a flexible automatic loading and unloading device and method for a roller
sewing machine. The device includes a material loading platform, a
motion controller, a material picking and auxiliary sewing mechanism, and a material unloading platform. The
motion controller is used to convert the coordinate information of the material picking, auxiliary sewing, and unloading into a multi-axis linkage
signal. The guide rail unit, the first rotating unit, and the terminal rotating unit perform the material picking and auxiliary sewing actions according to the
signal, and transfer the material to the material unloading platform. The method includes extracting the coordinate information of the material picking, auxiliary sewing, and unloading and converting the information into a multi-axis linkage
signal, and transmitting the multi-axis linkage signal to the material loading unit, the material picking and auxiliary sewing mechanism, and the material unloading platform to complete the material feeding, picking, auxiliary sewing, and unloading. The present invention can effectively replace manual loading and unloading and auxiliary sewing, and quickly adapt to changes in sewing contours, thereby improving sewing efficiency and quality.
