Abstract:
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.
