ABSTRACT:
An improved device for separating out single coins from a collective plurality of coins solves the problem of separating stacked coins, namely two or three coins lying one upon the other with their total thickness being smaller than or equal to that of the thickest coin. In accordance with the device, to separate the coins, a second coin stripping arm (15) embodied by a narrow and thin guide finger (16) is provided downstream of a first coin stripper (14), considered in the direction of rotation (Arrow 5) of the coin disc (3), the first coin stripper (14) being adjusted to the thickness of the thickest coin, and the guide finger (16) projecting beyond the disc outer edge and guiding the respective underlying coins (11) on the coin disc (3) directly into a guideway (8) above which a first conveyor belt (12) is disposed. Another conveyor belt (18) extending parallel to the first conveyor belt (12) runs above the guide finger (16) and pulls off any overlying coins (11) which rest on those coins (11) which lie directly on the coin disc (3) thereby returning those overlying coins to the coin disc (3). The guide finger (16) co-operates with a crescent-shaped spring-biased pivot or ball closing element (25) by which the entrance (7) is opened at every instance only to an extent permitting a single coin to pass along the front edge (17) of the guide finger (16) into the guideway (8).
