The work aims to adopt mechanism to ensure no friction between paper on high-speed paper fetching machine. The posture and motion requirements of the suction head on the condition of non-friction between papers were defined. By applying he motion characteristics of the cam linkage mechanism and considering the requirements of the motion law of the cam mechanism in high-speed movement, the paper fetching mechanism with cam five-bar was designed. The motion of the mechanism was verified by Adams simulation. By analyzing the displacement changes of two points on linkage of cam five-bar mechanism, the movement of the linkage as suction head was obtained. Through the motion simulation analysis of the mechanism, the suction head made intermittent linear motion with posture perpendicular to paper surface during fetching paper, thus achieving the predetermined target requirements. The cam five-bar mechanism can well meet the requirements of high-speed and non-friction between papers during fetching paper.
