First Claim
Patent Images
1. A coin processing machine for processing a plurality of coins of mixed denominations, comprising:
- a stationary sorting head; and
a rotatable disk for imparting motion to the plurality of coins,the stationary sorting head having a lower surface generally parallel to and spaced slightly away from the rotatable disc, the lower surface of the stationary sorting head forming a queuing channel and a coin exit station, the queuing channel having an interior wall against which the coins abut, the queuing channel having a first segment for receiving coins and aligning the coins along the interior wall and a second segment for moving the coins to an outer periphery of the sorting head such that a portion of each coin extends beyond the outer periphery; and
the rotatable disc including a resilient pad having a plurality of portions having at least one property having different values, said resilient pad comprising a first portion having a first stiffness and a second portion having a second stiffness different from the first stiffness, the second portion having a second stiffness being configured to provide a higher gripping force on coins disposed between the second portion of the resilient pad and the lower surface of the stationary sorting head than between the first portion of the resilient pad and the lower surface of the stationary sorting head.

Abstract
A resilient pad for a disc-type coin processing machine is provided with a first portion with a property having a first value and a second portion with the property having a second value, wherein the first value of the property is different than the second value of the property. The property may include, for example, stiffness or coefficient of friction.

11. A coin processing machine for processing a plurality of coins of mixed denominations, comprising:
-
a rotatable disc for imparting motion to the plurality of coins, the rotatable disc including a resilient pad with a central portion and an outer peripheral portion, the outer peripheral portion comprising a first portion having a higher stiffness than the central portion; a stationary sorting head having a lower surface generally parallel to and spaced slightly away from the rotatable disc, the lower surface forming a coin path leading to a coin exit station to which coins are discharged, the coin path moving the coins toward an outer periphery such that a portion of each coin extends beyond the outer periphery, while engaging said first portion of said resilient pad; a sensor disposed outside the periphery of the sorting head for obtaining information from the portion of each coin extending beyond the periphery of the sorting head. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of processing coins, comprising the acts of:
-
receiving the coins in a coin receiving region; imparting motion to the coins with a rotatable disc comprising a resilient pad with a central portion and an outer peripheral portion, one or more portions of the outer peripheral portion having a higher stiffness than the central portion; engaging the coins with a stationary sorting head during the act of imparting motion; moving coins along a coin path within the stationary sorting head to a registering area adjacent a periphery of the sorting head; and gripping, in said registering area, at least a portion of each coin between the stationary sorting head and said one or more portions of the outer peripheral portion having a higher stiffness than the central portion. - View Dependent Claims (19, 20, 21, 22, 23)

24. A coin processing machine for processing a plurality of coins of mixed denominations, comprising:
-
a rotatable disc for imparting motion to the plurality of coins, the rotatable disc including a substantially rigid disc having a resilient pad disposed thereupon; and a stationary sorting head having a lower surface opposing and spaced apart from the rotatable disc, the lower surface of the sorting head comprising features forming a coin path for biasing coins to an outer periphery of the sorting head such that a portion of the coins extends beyond said outer periphery of the sorting head in at least a sensing area having a coin sensor; wherein the stationary sorting head comprises a removable member disposed in the sensing area, the removable member having a coefficient of friction different than that of the surrounding portions of the stationary head lower surface, and wherein said removable member comprises a coefficient of friction higher than that of the surrounding portions of the stationary head lower surface. - View Dependent Claims (25, 26)
