Apparatus and method for sorting coins

A device for sorting coins, the diameter and thickness of which are within predefined size ranges, said device comprising:

• a storage container for unsorted coins,
• at least one coin conveying unit having two parallel, jointly driven, endlessly circulating pulling means, wherein an upper run of the pulling means, that conveys the coins upwards from the storage container and is oriented such that it raises in a conveying direction, forms part of the wall of the storage container, with a sliding bar extended in the conveying direction for supporting the coins during conveying, wherein the sliding bar is arranged between the pulling means in the region of the upper run, and with coin receptacles for the conveyed coins, wherein the coin receptacles have driver pins provided on the pulling means and assigned to one another in pairs, which project beyond the sliding bar by an extent exceeding the predefined greatest coin thickness,
• a coin separating unit for separating the coins conveyed from the storage container in the coin receptacles, with a shearing device for coins lying axially above one another in the coin receptacles, wherein the sliding bar, as a shearing device, has a run-on ramp, the height of which is less than the projection of the driver pins beyond the sliding bar and greater than the difference between the projection of the driver pins and the smallest predefined coin thickness, and with a return device for coins lying radially above one another in the coin receptacles, wherein the return device has a signal generator for detecting an extension of the coins in the conveying direction and a returner arranged downstream of the signal generator for returning the coins from the coin receptacle into the storage container,
• a coin recognition unit arranged downstream of the coin separating unit, as seen in the conveying direction, for identifying different types of coins by means of at least one characteristic feature of the separated coins, and
• a discharge unit for the separated coins interacting with the coin recognition unit and being arranged downstream of the coin recognition unit, as seen in the conveying direction,
• wherein the discharge unit is designed as a discharge unit for discharging coins of one single type and has at least one ejector, wherein the at least one ejector is controlled by a control unit in such a manner that the coins identified by the coin recognition unit are supplied to different collecting containers in accordance with the identified characteristic feature.
