ABSTRACT:
A device for detecting stacks of coins for use in a coins-packaging machine adapted to wrap each stack of a predetermined number of coins with wrapping paper, said device comprising a stacking cylinder of an electrically insulating material for receiving coins supplied through the upper inlet thereof and stacking the coins thus supplied face to face relation each other to form therein a stack of predetermined number of coins, an electrically conductive bottom plate disposed adjacent the lower open end of said stacking cylinder and adapted to support the stack of coins from the lower end and be removed therefrom for enabling the stack of coins to be discharged from the stacking cylinder into the next stage for wrapping, an electrode of cylindrical shape formed as part of inner wall of said stacking cylinder at a height of a little more distance than the height of said stack of coins from the lower end thereof, a relay and an electric power source therefor connected in series relation between said electrode and said bottom plate, whereby, when at least one coin of said stack is incorrectly positioned and the height thereof increases into contact with said electrode, electric current may flow through said stuck coins so that said relay may be energized to produce an output for detecting the incorrect stack condition of coins within said stacking cylinder.
