Patent CA-2344369-A1 (CA)
Inventor: ATKINSON MARK
IPC: B65G57/28
Filed: 1999-09-15
Abstract: Lithographic plates (26) are advanced along a conveyor belt (28). As the plates go over centre from the conveyor belt (28) they tilt downwardly and are driven downwardly by an assembly (16) towards a trolley (12). When the plates are at the bottom of their travel on the assembly (16) a lifting arm assembly (14) pivots to cause arms (32) to move up into contact with the plate and to cause the plates to go over centre such that they fall gently so that the face that previously faced downwardly now faces upwardly and away from a supporting face (36) of the trolley. Once the plate is securely on the belts (18) that drive the plate downwardly the plate is driven faster by the bands (18) until, just before the plate reaches the bottom of its travel, its speed is reduced so that the leading edge is inched down.
