Control apparatus for register stops and gripper fingers
Abstract
Abstract AN APPARATUS FOR SELECTIVELY CONTROLLING THE OPERATION OF REGISTER STOPS AND GRIPPER FINGERS ON A TRANSFER DRUM IN A REPRODUCTION APPARATUS HAVING A NON-ROTATING CAM AND A ROTATABLE FOLLOWER WHICH ARE LOCATED EXTERNAL TO THE TRANSFER DRUM. THE CAM IS SELECTIVELY MOVABLE BETWEEN AN INOPERATIVE POSITION WHICH IS REMOTE FROM THE TRANSFER DRUM AND AN OPERATIVE POSITION WHICH IS IMMEDIATELY ADJACENT THE TRANSFER DRUM. THE FOLLOWER ROTATES WITH THE TRANSFER DRUM AND OPERATES THE REGISTER STOPS AND GRIPPER FINGERS ON THE DRUM IN RESPONSE TO THE SHAPE OF THE CAM ONLY WHEN THE CAM IS IN ITS OPERATIVE POSITION. THE CAM IS MOVED INTO ITS OPERATIVE POSITION WHILE THE TRANSFER DRUM CONTINUES TO ROTATE BY A SOLENOID WHICH PIVOTS AN ARM AGAINST THE CAM AND MOVES IT INTO ENGAGEMENT WITH THE FOLLOWER.
