Abstract

1430915 Delivering sheets ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER AG 7 March 1974 [9 March 1973] 10294/74 Heading B8R A gripper which, in normal operation, moves in a closed path between a position over a sheet stack and a position remote from the stack, and which, while over the stack, grips a sheet delivered from a printing-machine and deposits it on the stack, is, in the event of sheet jamming or entanglement and while the machine is still running, held in its position remote from the stack by a locking mechanism which prevents the horizontal component of the gripper drive motion from being transmitted to the gripper to move it back to its position over the stack, which component is directed in the opposite direction to the delivery movement of the sheets. The vertical component is provided by a cam 16, Fig. 1, and the horizontal component by a camoperated reciprocating drive rod 1, Figs. 1 and 2, and a spring 6. The movement of the rod 1 by the spring 6 to move the gripper towards the stack 5 is prevented by a locking pawl 8 when the latter is swung about its pivot 10 into the path of a projection 7 on the rod 1 on energization of an electromagnet 12 by closing a switch 15. If this occurs when the projection 7 is to the left of the pawl 8, the resultant swinging movement of the pawl 8 when hit by the projection as the gripper moves away from the stack is taken up by a spring 19 to prevent damage to the magnet. The pawl may alternatively be moved pneumatically or manually.
