Abstract

The described device for separating coins comprises a rotatable base disc ( 32 ), a delimiting element ( 34 ) and a driver disc ( 36 ). A circular ring-shaped sorting track ( 12 ) is arranged eccentrically relative to the base disc ( 32 ). The driver disc ( 36 ) and a circularly arranged conveying element ( 14 ) interact in a transfer region ( 38 ) such that the lowest layer of coins among a quantity of coins conveyed by the driver disc ( 36 ) are pushed underneath the conveying element ( 14 ), clamped thereat and conveyed further.

First claim

The invention claimed is:

1. A device for separating coins, comprising:
a circular sorting track ( 12 );
an elastic conveying element ( 14 ) for conveying the coins along the circular sorting track ( 12 );
a base disc ( 32 ) arranged eccentrically relative to the circular sorting track ( 12 ) and rotatable about an axis inward of the elastic conveying element ( 14 );
a driver disc ( 36 ) arranged concentrically on the base disc ( 32 ) and rotatable about the axis of the base disc ( 32 );
a delimiting element ( 34 ) upward of the base disc ( 32 ) and cooperating with the base disc ( 32 ) for delimiting a receiving area with an open top for receiving a quantity of coins to be separated;
a transfer region ( 38 ) in an area of the delimiting element ( 34 ) adjacent the base disc ( 32 ) and between the driver disc ( 36 ) and the elastic conveying element ( 14 ), the transfer region ( 38 ) having an opening for passage of the coins and for feeding the coins to the elastic conveying element ( 14 ), so that the conveying element ( 14 ) feeds separated coins along the circular sorting track ( 12 ) to sorting devices ( 18 to 30 ),
and wherein the driver disc ( 36 ) and the conveying element ( 14 ) interact in the transfer region ( 38 ) such that the coins of a lowest layer of a quantity of coins conveyed by the driver disc ( 36 ) are pushed underneath the conveying element ( 14 ) and are clamped thereat.

2. The device of claim 1 , wherein the driver disc ( 36 ) is rigidly connected to the base disc ( 32 ).

3. The device of claim 1 , wherein the driver disc ( 36 ) has a height that is smaller than the smallest thickness of the coins ( 52 ) to be processed.

4. The device of claim 1 , wherein a transport speed (v 3 ) of the conveying element ( 14 ) is higher than a transport speed (v 2 ) of the coins that are transported by the lateral surface of the driver disc ( 36 ).

5. The device of claim 1 , wherein a center of the base disc ( 32 ) is arranged within the circular track of the sorting track ( 12 ) such that the base disc ( 32 ) and the conveying element ( 14 ) overlap in the transfer region ( 38 ).

6. The device of claim 1 , wherein along the circular track of the sorting track ( 12 ), as viewed in transport direction of the individual coins, a coin checking device ( 42 ), a curve ejector ( 44 ), a rejecting ejector ( 46 ) and a plurality of sorting ejectors ( 18 to 30 ) are arranged.

7. The device of claim 1 , wherein the conveying element ( 14 ) is arranged with respect to a lateral surface of the driver disc ( 36 ) such that coins having a diameter range between 14 and 33 mm can be clamped underneath the elastic conveying element ( 14 ).

8. The device of claim 1 , wherein the transfer region ( 38 ) is substantially wedge-shaped so that a distance between an outer circumference of the driver disc ( 36 ) and the elastic conveying element gradually decreases in a rotating direction of the base disc ( 32 ) to a minimum distance (A) that is shorter than the diameter of the smallest coin to be separated by the device.

9. The device of claim 1 , wherein the driver disc ( 36 ) has a friction coating, in particular a rubber coating, on its lateral surface.

10. The device of claim 9 , wherein the device does not comprise any stationary coin separator ( 41 ).

11. The device of claim 9 , wherein a distance (A) between the lateral surface of the driver disc ( 36 ) and the conveying element ( 14 ) is shorter than the diameter of the smallest coin to be separated by the device.

12. The device of claim 9 , wherein the conveying element ( 14 ) comprises a ring-shaped elastic clamping ring ( 60 ) and a holding ring ( 62 ) made of a rigid material and connected to the clamping ring.

13. The device of claim 12 , wherein the ring-shaped elastic clamping ring ( 60 ) is made of polyurethane or of a rubber material.

14. The device of claim 1 , wherein the sorting track ( 12 ) has an inner track boundary ( 48 ) extending concentrically relative to the conveying element ( 14 ), and that the separated coins are transportable along the inner track boundary ( 48 ) by the conveying element ( 14 ).

15. The device of claim 14 , wherein the sorting track ( 12 ) has an outer track boundary ( 16 ) extending concentrically relative to the conveying element ( 14 ), and the separated coins ( 52 ) are transportable along the outer track boundary ( 16 ) by the conveying element ( 14 ).

16. The device of claim 14 , wherein, as viewed in a transport direction of the separated coins, an orientation device ( 40 ) is arranged after the transfer region ( 38 ) and orients the separated coins such that they are conveyed along the inner track boundary ( 48 ) or along the outer track boundary ( 16 ) by the conveying element ( 14 ).

17. The device of claim 1 , wherein an outer circumference of the driver disc ( 36 ) faces an inner circumference the elastic conveying element ( 14 ) with a distance therebetween gradually decreasing farther into the transfer region ( 38 ) in a rotating direction of the base disc ( 32 ).

18. The device of claim 17 , wherein a minimum distance (A) between the outer circumferential surface of the driver disc ( 36 ) and the circular conveying element ( 14 ) is shorter than the diameter of the smallest coin to be separated by the device.

19. The device of claim 17 , wherein a corner between an inner circumferential surface of the circular conveying element ( 14 ) and a lower surface of the circular conveying element ( 14 ) is chamfered to facilitate entry of the coins between the circular conveying element ( 14 ) and the sorting track ( 12 ).
