COIN DISCRIMINATION APPARATUS AND METHOD

摘要

A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel (52), are singulated by a coin pickup assembly configured to reduce jamming. A coin rail (56) assists in providing separation between coins as they travel past a sensor (58). The sensor provides an oscillating electromagnetic field generated on a single sensing core (214). The oscillating electromagnetic field is composed of one or more frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties. Objects recognized as acceptable coins, using the sensor data, are diverted by a controllable deflecting door (62), to tubes for delivery to acceptable coin bins (210).
