Design of Automatic Control System for Hand-made Carpet Tufting Machine

Abstract

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.
