A device for vertically conveying coins including a lower horizontal guide path, a vertical guide path, an approximately arc-shaped deflecting path connecting the lower horizontal guide path and the vertical guide path. Each of the path conveys the coins in a lying fiat position. At least one conveyor belt is provided. Rollers are provided whereby the conveyor belt is led around the rollers. Deflecting rollers are arranged at space locations from the guide paths and the from the arc-shaped deflecting path. With this structure, an essentially constant conveying gap is formed by the thickness of the coins being conveyed between the guide paths and the deflecting paths and the conveyor belt. Structure for feeding the coins, conveyed lying flat one by one, is arranged at the beginning of the lower horizontal guide path. Structure for transferring the coins being conveyed is arranged at the top end of the vertical guide path. At the beginning of the lower horizontal guide path there is preferably provided structure for identifying the denomination of the coins and for counting the coins, and or for presorting and conveying the coins according to denomination and/or for sorting out foreign coins. The end of the vertical guide path is formed by a dispenser hood with a coin guide plate joining it. An additional arc-shaped deflecting path with a connected upper horizontal guide path and with rollers and deflecting rollers associated with them for guiding a conveyor belt, is arranged at the top end of the vertical guide path.

Device for vertically conveying coins

Device for counting and sorting coins belonging to a set of coins

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).

Device for separating single coins

An arrangement for counting the values of different-denomination coins and other disk-shaped objects in which the coins are transported in an irregular sequence with their rims along a rectilinear guiding edge on a guide track. A scanning head identifies the coin, and is located at the start of the rectilinear guiding edge. The scanning head has several photoconductor strands having free ends located at varying distances from the guiding edge. Photocells are connected to the other ends of the strands, and a light-beam element illuminates the free ends of the photoconductor strands. The photoconductor strands and the light-beam element are separated by a scanning gap for passage of the coins. The photoconductor strands are located along a line perpendicular to the guiding edge inside a holder which is inserted in the guide track. The free ends of the photoconductor strands are flush with the surface of the guide track. One photoconductor strand is associated with each of the coins of varying diameter.
