Abstract

Abstract In accordance with the invention a coin sorter is provided which sorts mixed denominations of coins. The coin sorter comprises a rotatable disc (10) having a resilient surface (27) and a stationary disc (16) having its first surface positoned proximate to the resilient surface (27) of the rotatable disc (10). The two discs (10,16) are positioned sufficiently close such that coins placed between the two disc surfaces are pressed into the resilient surface (27) by pressure from the stationary disc (16) surface. Accordingly, coins cannot move on the rotatable disc (10) and, as a result, they rotate with the rotatable disc (10). Radial movement of the coins is urged by centrifugal force from the coin rotation, but such movement is prevented by the coins pressed engagement with the resilient surface. Selected areas of the stationary disc (16) are recessed so as to release coins from their pressed engagement with the resilient surface and thereby allow radial movement of the released coins in response to centrifugal force. The selected areas of the stationary disc which are recessed, guide the coins along a path (40,46,50,52,54,56) which results in each denomination of coin escaping from between the two discs (10,16) at different positions (50,52,54,56) along the periphery of the stationary disc (16). A means (47) is provided to remove the upper coin from stacked or shingled coin combinations. Particularly, the means (44) may be an arcuate elastomer member which retards movement of the upper coin whiie allowing the lower coin to rotate freely. Alternatively, the means may be a recess in the stationary disc entrance allows only single layer coins to enter the recess by sweeping the surface of the lower coin and recirculating any stacked and shingied coins removed thereby. Recesses and ridges (42) are provided on the underside of the stationary disc (16) which recirculate improperly aligned coins. In particular, a ridge (47) is provided which recirculates misaligned coins to a recessed area which initially receives coins from the center opening of the stationary disc (16). A portion of the recesses in the stationary disc (16) which guide correctly aligned coins are configured to be approximately equal to the largest diameter coin in order to facilitate correct coin alignment. Another portion of the recesses provide an ejection route for misaligned coins which leads the coins back to the recessed area which initially accepts coins into the area between the two discs (10,16). Yet another portion of the recesses in the stationary disc (16) allow the smallest diameter coin denomination smooth and quick release between the two discs (10,16).

A coin sorter apparatus for receiving and sorting Mixed coins by denomination comprising in combination: a rotating disc (10) having a resilient surface (27) for receiving said mixed denomination coins and imparting a rotational movement to said mixed denomination coins, an annular shaped stationary disc (16) having a surface substantially parallel with said resilient surface (27) and positioned sufficiently close to said resilient surface (27) so that a portion of the stationary disc (16) presses coins in contact therewith into the opposed resilient surface (27) so that the resiliency of the surface (27) urges the coins against the stationary disc (16) with sufficient pressure to prevent radial movement of coins by centrifugal force due to rotation of the rotating disc (10), selected areas of the surface of said stationary disc (16) being recessed for releasing any coins entering such recessed areas from the pressure of said resilient surface (27) and thereby permitting radial movement of coins within the recessed area by centrifugal force due to rotation of the rotating disc (10), a first selected area (40) of recesses on the underside of said stationary disc (16) for receiving and rotating mixed denomination coins into the region between the two discs (10,16), a second selected area (40) of recesses on the underside of said stationary disc (16) for removing coins stacked or shingled on another coin, a third selected area of recesses on the underside of said stationary disc (16) for receiving coins from said second area and said recesses (46,40) in said third area regions for releasing coins from a pressed engagement with said resilient surface (27) and thereby permitting radial movement of coins within said regions by centrifugal force, and said regions being shaped to guide coins in a single file along a predetermined path (40) to predetermined radial positions on the rotating disc (10), a fourth selected area of recesses on the underside of said stationary disc (16) for receiving coins from said third area and effecting a pressed engagement with said rotating disc (10) and with said recesses of said fourth area releasing coins in said fourth area from pressed engagement and being shaped to permit coins of different sizes to radially escape by centrifugal force from between the surfaces of said stationary disc (10) and said rotatable disc (16), at different preselected positions (50,52,54,56) along the periphery of said stationary disc (16), a first recess (46) in said third selected area of recesses located to intercept improperly aligned coins in said third selected area of recesses, and radially inwardly directing said improperly aligned coins so as to return the improperly aligned coins to said first selected area of recesses, and said first recess (46) in said third selected area having substantially a ramp shape with respect to the circumferential movement of coins in said third selected area of recesses with said ramp shape being sufficiently steep so as to affect a rapid interception and movement of improperly aligned coins through said first recess (46) and into said first area such that the backlogging of exiting, improperly aligned coins in said first recess is avoided by the rapid throughput.
Claim 2
