US Patent:

54295505, Jul 4, 1995

Filed:

Sep 1, 1993

Appl. No.:

8/115319

Inventors:

Richard A. Mazur - Naperville IL
Gary Watts - Buffalo Grove IL
Donald E. Raterman - Deerfield IL
Robert J. Crawford - Palatine IL

Assignee:

Cummins-Allison Corp. - Mt. Prospect IL

International Classification:

G07D 316

US Classification:

453 10

Abstract:

A coin sorter for sorting mixed coins by denomination. The apparatus comprises a rotatable disc which has a resilient surface for receiving coins and imparting rotational movement to the coins. A stationary sorting head has a contoured surface spaced slightly away from and generally parallel to the resilient surface of the rotatable disc. The stationary sorting head sorts and discharges coins of different denominations at different exits around the periphery of the stationary sorting head. The sorting head includes a separate exit channel for each denomination of coin, and a sensor for each coin denomination within the exit channel for that denomination. An encoder monitors the movement of a sensed coin on the rotating disc downstream of the sensors by monitoring the angular movement of the disc. Further, a coin discriminator is used to detect foreign and counterfeit coins and to prevent the detected invalid coins from being discharged with the valid coins.

International Classification:

G07D 314

US Classification:

194318

Abstract:

A coin sorter for sorting mixed coins by denomination includes a rotatable disc, a drive motor for rotating the disc, and a stationary sorting head having a lower surface generally parallel to the upper surface of the rotatable disc and spaced slightly therefrom. The lower surface of the sorting head forms a plurality of exit channels for guiding coins of different denominations to different discharge stations around the periphery of the disc. A plurality of coin sensor/discriminators are mounted in the stationary sorting head over the rotatable disc for discriminating between valid and invalid coins guided by said stationary sorting head. At least one coin sensor/discriminator is mounted in each of the plurality of exit channels.
