Abstract

Coin processing apparatuses, such as consumer or commercial coin processing apparatuses for counting and/or sorting coins, are described herein. The apparatuses can include coin conveyors having a plurality of individual coin carriers linked together to form a chain. In some embodiments, each of the coin carriers includes a corresponding pocket that is configured to receive a coin from a coin hopper as the carrier chain passes through the coin hopper during its cycle. The coin carriers can carry the coins past one or more sensors for identification or “discrimination” of the coin denomination. After discrimination, the coins can be knocked from the carrier pockets and into, e.g., a selected coin chute for transfer to a collection bin.

24. The coin processing machine of claim 1 wherein each of the coin carriers further includes a biasing member that biases the head portion of the coin mover against a seat in the coin carrier.

25. The coin processing machine of claim 24 wherein the head portion defines a first surface portion of the coin pocket, and wherein the first surface portion is generally flush with an adjacent second surface portion of the coin pocket when the biasing member biases the head portion against the head portion against the seat in the coin carrier.

26. The coin processing machine of claim 24 wherein application of a force to a distal end portion of the stem compresses the biasing member and drives the head portion of the coin mover away from the seat in the coin carrier.

27. The coin processing machine of claim 1 wherein the bore is centrally disposed in the coin pocket.

28. The coin processing machine of claim 1 wherein the head portion of the coin mover is concentrically disposed in the coin pocket.

29. The coin processing machine of claim 1 wherein the coin hopper is configured to receive a range of valued coins from a smallest desired coin to a largest desired coin, and wherein the coin pocket is sized to receive and carry any coin in the range of valued coins.

30. The coin processing machine of claim 1 wherein the coin hopper is configured to receive a range of valued coins from a U.S. dime to a U.S. 50¢

piece, and wherein the coin pocket is sized to receive and carry any coin in the range of the valued coins.

9. A system for counting and/or sorting coins, the system comprising:

a first wheel;

a second wheel spaced apart from the first wheel;

a plurality of coin carriers, wherein each of the coin carriers is pivotally coupled to two other of the coin carriers in end-to-end relationships, the plurality of coin carriers forming a continuous chain that operably extends around the first and second wheels, wherein each of the coin carriers includes a coin pocket; and

a coin mover having a head portion operably positioned in the coin pocket;

a coin hopper configured to receive a plurality of coins of random denominations, wherein rotation of at least one of the first and second wheels moves the coin carriers adjacent to the coin hopper, wherein the coin pockets are configured to receive coins from the hopper, and wherein the coin movers are configured to support the coins in the individual coin pockets as the coin carriers move the coins away from the coin hopper; and

an actuator configured to cause the coin movers to displace the coins from the individual coin pockets.

10. The system of claim 9 wherein the first and second wheels are coplanar, wherein the continuous chain extends in a path around the first and second wheels, and wherein the path has a lower segment that extends between the first and second wheels proximate a lower portion of the coin hopper.

11. The system of claim 9 wherein the first and second wheels are spaced apart from each other in a horizontal direction, wherein the continuous chain extends in an oval path around the first and second wheels, the oval path having a lower segment that extends adjacent to the coin hopper and an upper segment positioned above the lower segment, wherein the coin machine further comprises:

at least one coin chute, the coin chute having an inlet positioned to receive coins from the coin carriers as the coin carriers as the coin carriers move along the upper segment of the oval path.

12. The system of claim 9 wherein the continuous chain circulates in a path around the first and second wheels, and wherein the system further comprises:

a coin sensor positioned adjacent to the path, wherein the coin sensor is configured to sense at least one property of the coins as they move past the coin sensor in the individual coin pockets, and

wherein the actuator is configured to cause the coin movers to displace the coins from the individual carriers based at least in part on the property sensed by the coin sensor.
