Design of Automatic Control System for Hand-made Carpet Tufting Machine
Tufting machines are computer controlled robots which using special commands to move the robotic arm accordingly to produce carpets. The robotic arm can be driven with 4-axes coordinately to follow the path defined by a series of nodes and tuft stitches in the backing fabric along the contour. The paper gives some analysis and solution on how to control the mechanism in a reliable manner and avoid impact damage while abrupt points are encountered. Experiments verified the effectiveness of the mechanical & electrical structure and its control schemes.
