Vorrichtung zum Ausscheiden von unannehmbaren Münzen für eine Münzensortiermaschine

An unacceptable coin removing apparatus for a coin handling machine includes a rotatable disk (1) for receiving coins (c) deposited into the coin handling machine and feeding coins one by one into a coin passage (2) provided with a reference guide rail (3) and a guide rail (4) facing the reference guide rail (3), transporting belts (8,9) for transporting coins (c) in the coin passage (2), sensors (5,11) for detecting coins (c), a first projecting member (17) which can be projected from the reference guide rail (3) into the coin passage (2), a second projecting member (20) which can be projected from the guide rail (4) into the coin passage (2), a coin collecting opening (10) and a controller (40) for controlling the operation of the first projecting member (17), the second projecting member (20), the transporting belts (8,9) and the rotatable disk (1). When the sensors (5,11) detect an acceptable coin (c), the controller (40) does not actuate the first (17) and second (20) projecting members. When the sensors (5,11) detect an unacceptable coin (c) or a foreign article, the controller (40) projects the first or second projecting member (17,20), thereby leading the coin (c) to the coin collecting opening (10) and removing it. When it is unclear whether or not a coin (c) is acceptable, the controller (40) projects the first and second projecting members (17,20), reversely drives the transporting belts (8,9) and the rotatable disk (1) so as to return the coin (c) onto the rotatable disk (1) and then repeats the above described operation until it becomes clear whether or not the coin (c) is acceptable. According to the unacceptable coin (c) removing apparatus, unacceptable coins (c) or foreign articles can be efficiently and reliably removed.
