Title:
SWING DEVICE OF SHEET ROTARY PRESS
Document Type and Number:
Japanese Patent JP3638074
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent registering dislocation during printing by providing an elastic member for urging a swing device in the reverse direction to the swing direction thus far in its both swing end limits.
SOLUTION: During rotation in a swing start and end of a gripper claw device 25, a tortion bar 35 regulated in its rotation to the frame via a holder 40 by its one end is distorted in the rotation direction of the gripper claw device 25, distortion urging force in the reverse direction to the rotation direction of the gripper claw device 25 is accumulated to be maximum at the swing terminal end. Accordingly, the gripper claw device 25 is made slow in its speed by urging force as being near the swing terminal end, so that an axial torque applied on the swing shaft 2 is reduced, and the occurrence of oscillation is restrained at the time of stopping at the swing terminal end. This is such that since the gripper claw device 25 turns around at the swing terminal end and an axial torque applied to the swing shaft 2 is reduced even in the swing start end at the insertion plate tip end part of a paper feeder for gripping the paper end by the gripper claw 31 of the gripper claw device 25, the occurrence of oscillation is restrained even at stoppage at the swing start end.
