Conjugate cam design method of swing grippers mechanism on printing press

This paper proposes a method for the design of conjugate cam of swing grippers mechanism on printing press. The polynomial of 5 degree is adopted to simulate the motion law of the grippers, and a general mathematical model is established according to the technological conditions. Based on the matrix method, the kinematical analysis model is built to gain the motion law of the conjugate cam's follower. The parametric expressions for the conjugate cam profiles are given. The effectiveness of the proposed method is proved through a design example of the swing grippers mechanism.
