The work aims to provide a multifunctional automatic coin sorter integrated with classification, counting and sorting for coin sorting, so as to reduce labor cost and improve coin sorting efficiency. Coin sorter was mainly composed of vibrating separator plate, photoelectric sensor, stopping mechanism, picking device, control system and uid crystal display. The vibrating plate provided its power source. After passing by the sorting area composed of material-splitting rod and slot, the coins entered their respective feeding channel and moved forward. The optical sensor respectively sensed the falling signal of coins in each feeding channel, and passed it to the control system. The control tem carried out coin counting, amount statistics and other work after obtaining the signals of photoelectric sensor. When the coin counting met the number set for stopping, the control system controlled the operations of 3 stopping motors. After the stopping mechanism stopped the stock and was manually reset with coins taken out, the stock stop ceased stock stopping and the coin sorting continued. The effective working space of prototype was 900 mm×600 mm×420 mm, and the net weight of whole machine was 40 kg. The prototype could sort new 1 yuan coin (25 mm), 5 jiao coin (20.4 mm) and 1 jiao coin (19 mm). The sorting rate was up to 500 coins/min. The designed multifunctional coin sorter can realize the automatic sorting, counting and collation of 3 kinds of coins, featured by small floor space, high cost performance, adjustable speed and large upgrade space, etc.
