Sheet stacking apparatus
View Patent ↗A banknote stacker comprising at least one first scissors linkage acting to extend a pusher into a cashbox, and at least one second scissors linkage acting transversely to said first to extend a lateral portion of said pusher to flatten a note in the cashbox.
1. A stacker for stacking value sheets from a sheet path into a receptacle having a sheet retaining plane, comprising a stacking member operating to push a sheet with a stroke operation into the receptacle in a first direction, generally transverse to the sheet retaining plane, onto a stack, and in a second direction transverse to the first direction to flatten the sheet against the stack, the stacking member comprising a transversely extending member, the stacker further comprising at least one transverse actuator for moving the transversely extending member in the second direction, the actuator positioned to the side of the note stack and, wherein the stacker has a first state in which the actuator is arranged so as not to drive the transversely extending member when said stacking member moves in said first direction, and a second state after the transversely extending member is moved into engagement with the actuator wherein the actuator is arranged to drive the transversely extending member.
2. A stacker according to claim 1 , in which the transversely extending member comprises at least one roller arranged to roll transversely over the note, and a roller support member.
3. A stacker according to claim 2 , in which the roller support member is an axle on which each roller is rotatably mounted.
4. A stacker according to claim 1 , in which the transversely extending member engages with at least one guide on the transverse actuator.
5. A stacker according to claim 4 , in which the guide is a slot into which the transversely extending member engages and by which it is entrained.
6. A stacker according to claim 1 , in which the transverse actuator is located within the receptacle.
