Sheet gripping device

Abstract

Abstract A SHEET GRIPPING DEVICE INCLUDES A GRIPPER ASSEMBLY NONROTATABLY MOUNTED ON A GRIPPER SHAFT. AN LINE MEMBER ROTATABLY SUPPORTS THE GRIPPER SHAFT ADJACENT ONE END AND IS NONROTATABLY SECURED TO AN INTERMEDIATE SHAFT ADJACENT THE OTHER END. A FIRST CAM FOLLOWER LEVER IS CONNECTED TO THE INTERMEDIATE SHAFT AND IS ARRANGED TO OSCILLATE THE END OF THE LINK MEMBER SUPPORTING THE GRIPPER SHAFT. A SECOND CAM FOLLOWER LEVER IS NONROTATABLY CONNECTED TO THE GRIPPER SHAFT AND HAS A CAM ROLLER URGED INTO ABUTTING RELATION WITH A CAM SURFACE FIXED ON TEH CYLINDER. MOVEMENT OF THE LINK MEMBER BY THE FIRST CAM FOLLOWER MOVES THE GRIPPER ALONG A PATH SIMILAR TO THE CAM SURFACE AGAINST WHICH THE CAM ROLLER ON THE SECOND CAM FOLLOWER IS URGED. THE CONFIGURATION OF THE CAM MEMBERS DETERMINES THE PATH FOLLOWED BY THE GRIPPER ASSEMBLY. THE GRIPPER ASSEMBLY INCLUDES A LEVER NONROTATABLY SECURED AT ONE END TO THE GRIPPER SHAFT WITH A BRACKET EXTENDING LATERALLY THEREFROM. THE GRIPPER MEMBER HAS A LATERALLY EXTENDING GRIPPER FINGER THAT ABUTS A GRIPPER PAD ON THE CYLINDER WITH AN END PORTION EXTENDING LATERALLY THEREFROM. THE GRIPPER MEMBER ALSO HAS AN INTERMEDIATE PORTION WITH AN ADJUSTING SCREW MOVABLE LONGITUDINALLY RELATIVE TO THE GRIPPER MEMBER. THE GRIPPER MEMBER IS SLIDABLY POSITIONED ON THE LEVER AND A SPRING BETWEEN THE BRACKET AND GRIPPER MEMBER END PORTION URGES THE GRIPPER FINGER AGAINST THE GRIPPER PAD. UPON UPWARD MOVEMENT OF THE LEVER, THE BRACKET THEREON CONTACTS THE ADJUSTING SCREW ON THE GRIPPER MEMBER AND LIFTS THE GRIPPER FINGER FROM THE GRIPPER PAD.
