Abstract

A stacking apparatus for value documents, having a stack deposit device and a braking device which is arranged along the transport path of the value documents immediately before the stack deposit device. On the transport shaft of the braking device at least one driving roller is firmly mounted and at least one roller rotatably supported on the transport shaft. At least one cam roller is firmly mounted on a braking shaft of the braking device and at least one eccentric roller. By a rotation of the braking shaft, the eccentric roller can electively be brought in engagement with the opposing driving roller so that a value document becomes clamped between these, or be brought out of engagement with the opposing driving roller, so that the value document is no longer clamped between these, but rather is brakable by the engagement between the cam roller and the rotatably supported roller.

First claim

The invention claimed is:

1. A stacking apparatus for stacking value documents which are individually transported to the stacking apparatus by a transport system along a transport path at a transport velocity, the stacking apparatus comprising:
a stack deposit device for receiving a stack of the value documents, and
a braking device for braking the value documents which were individually transported to the stacking apparatus by the transport system, wherein the braking device is arranged immediately before the stack deposit device along the transport path of the value documents,

wherein
the braking device has a transport shaft and a braking shaft oriented parallel thereto, between which the respective value document is transported through,
on the transport shaft there is mounted at least one driving roller, which is firmly mounted on the transport shaft, and there is mounted at least one roller rotatably supported on the transport shaft, and
on the braking shaft there is mounted at least one cam roller, which is firmly mounted on the braking shaft, and there is mounted at least one eccentric roller,
wherein the at least one eccentric roller has an eccentric core firmly mounted on the braking shaft in an eccentric position, and
wherein a cam of the cam roller and the eccentric core of the eccentric roller are mounted on the braking shaft at a mutual angular offset such that by a rotation of the braking shaft it can be attained that
the cam of the cam roller can be brought into engagement with the opposing rotatably supported roller so that a value document transported through therebetween is clamped between the cam of the cam roller and the rotatably supported roller.

2. The stacking apparatus according to claim 1 , wherein the roller rotatably supported on the transport shaft and the cam roller mounted on the braking shaft respectively lie opposite each other with regard to the transport path of the value documents.

3. The stacking apparatus according to claim 1 , wherein the driving roller mounted on the transport shaft and the eccentric roller mounted on the braking shaft respectively lie opposite each other with regard to the transport path of the value documents.

4. The stacking apparatus according to claim 1 , wherein the at least one eccentric roller has an eccentric core firmly mounted on the braking shaft in an eccentric position, and
wherein a cam of the cam roller and the eccentric core of the eccentric roller are mounted on the braking shaft at a mutual angular offset such that
in that angle range of the braking shaft rotation in which the eccentric roller is urged onto the opposing driving roller, the cam of the cam roller is not in engagement with the opposing rotatably supported roller, but rather there remains a space between the cam of the cam roller and the opposing rotatably supported roller, and
in that angle range of the braking shaft rotation in which the cam of the cam roller is in engagement with the opposing rotatably supported roller, the eccentric roller is not in engagement with the opposing driving roller, but rather there remains a space between the driving roller and the eccentric roller in which space the respective value document is not urged against the driving roller by the eccentric roller, but rather is brakable relative to said rollers.

5. The stacking apparatus according to claim 1 , wherein on a lower shaft of the braking device, which is arranged below the transport path of the value documents, there is firmly mounted on the lower shaft at least one auxiliary element which is configured such that the rearward end of the value document is urged in the direction of the stack deposit device upon rotation of the lower shaft.

6. The stacking apparatus according to claim 5 , wherein the auxiliary element protrudes beyond a cam radially in the angle range of the cam of the cam roller.

7. The stacking apparatus according to claim 1 , wherein the braking device has two mutually coaxial braking shafts which are axially spaced apart and are rotatable independently of each other, wherein on each of the two braking shafts there is firmly mounted at least one cam roller, and there is firmly mounted axially offset from the cam roller at least one eccentric roller, which has respectively an eccentric core firmly mounted on the respective braking shaft in eccentric position and an eccentric roller rotatably supported on the eccentric core.

8. The stacking apparatus according to claim 7 , wherein the stacking apparatus has a control device which is adapted for rotating the two coaxial braking shafts with a mutual time offset and/or rotating them at different angular velocities in the angle range in which the value document is clamped.

9. The stacking apparatus according to claim 7 , wherein the control device is configured such that for one of the two coaxial braking shafts at which the value document arrives earlier, the rotation is started earlier, so that the value document is brought in engagement with the cam of the respective cam roller and the respective rotatably supported roller sooner on the side of said braking shaft than on the side of the other braking shaft.

10. The stacking apparatus according to claim 1 , wherein the at least one eccentric roller has an eccentric core firmly mounted on the braking shaft in an eccentric position, and
wherein a cam of the cam roller and the eccentric core of the eccentric roller are mounted on the braking shaft at a mutual angular offset such that by a rotation of the braking shaft it can be attained that
the eccentric roller can be brought into engagement with the opposing driving roller such that the value document is clamped between the eccentric roller and the driving roller.

11. The stacking apparatus according to claim 1 , wherein the braking shaft is arranged below the transport path of the value documents, and on the braking shaft there is firmly mounted at least one auxiliary element which is configured such that the rearward end of the value document is urged in the direction of the stack deposit device upon rotation of the lower shaft.

12. The stacking apparatus according to claim 1 , wherein the transport shaft is arranged below the transport path of the value documents, and on the transport shaft there is firmly mounted at least one auxiliary element which is configured such that the rearward end of the value document is urged in the direction of the stack deposit device upon rotation of the lower shaft.

13. The stacking apparatus according to claim 1 , wherein the braking device has two mutually coaxial braking shafts which are axially spaced apart and are rotatable independently of each other, wherein on each of the two braking shafts there is firmly mounted at least one cam roller.

14. The stacking apparatus according to claim 13 , wherein there is firmly mounted axially offset from the cam roller at least one eccentric roller, which has respectively an eccentric core firmly mounted on the respective braking shaft in an eccentric position and an eccentric roller rotatably supported on the eccentric core.

15. The stacking apparatus according to claim 1 , wherein the at least one eccentric roller has an eccentric core firmly mounted on the braking shaft in an eccentric position, and an eccentric roller rotatably supported on the eccentric core.

16. A method for stacking value documents using a stacking apparatus, the value documents being individually transported to the stacking apparatus by a transport system along a transport path at a transport velocity, the method comprising:
braking the value document
