Abstract:

In order to improve the utilization rate of industrial robots in textile and garment industry, and to expand the application range of electrostatic adsorption end-effector, this research worked to solve the problem in automatic fabric grasping and transferring during garment processing, taking weft knitted fabrics as example. Through analyzing the structural characteristics of weft knitted fabrics, the influence of fiber composition on the adsorption capacity, the three-dimensional structure simulation model of fabric element and the calculation model of fabric relative dielectric constant were established respectively, on the basis of which the electrostatic adsorption model of weft knitted fabrics was built. The adsorption force model was verified by simulation software. The results show that the model can calculate the adsorption capacity of electrostatic plate to weft knitted fabric. This research provides a new idea for realizing automatic grasping and transferring of cloth.

Key words: garment processing, electrostatic adsorption, fabric modeling, weft knitted fabric, cloth graping, manipulator, industrial robot
