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.

Abstract: A disc-type coin sorter for sorting coin mixtures which include at least one coin denomination made of a soft metal such as aluminum, the sorter has a rotatable disc having a resilient top surface, a motor for rotating the disc, a stationary sorting head having a lower surface positioned over and closely adjacent to the upper surface of the disc and having an opening in the central region thereof for feeding coins between the opposed surfaces of the disc and sorting head, the lower surface of the sorting head being contoured to align the coins in a single file and single layer of coins, and then sorting the coins according to their respective sizes, the contoured lower surface having at least one region for pressing the soft-metal coins into the resilient pad, and at least one rotatable bearing member mounted in the pressing region of the sorting head for engaging soft-metal coins passing thereunder so as to provide a rotatable bearing surface which eliminates or reduces galling of the soft metal of the coin
