Automatic coin refill system - is for coin delivery tube of automatic machine with electronic pick-up control of coin height

摘要

The coins move individually over a spring-mounted path which is vibrated by an electrical vibrating magnet. This magnet is switched on and off by two oscillators according to the height of the column of coins in the delivery tube. The oscillators are dampened and improved by means of two coils wound round the delivery tube and acting as sensors. The spring mounted path can be a vibrating cone with a web on which the coins are isolated. The oscillators are in an electronic circuit including an amplifier and a flip-flop control unit.
