Coin wrapping machine

Abstract

An automatic coin wrapping machine has a coin dispenser which forms coins into a single file and moves them along a track past a counting star wheel to a downwardly curved discharged chute. Coins leaving the discharge chute enter a stacking tube where they are formed into a stack. The bottom of the tube is closed by a movable gate which is vibrated to assist stacking. The formation of a proper stack is sensed by an optical sensor that checks the height of the stack. When a proper stack is formed, the gate is removed and the stack of coins is lowered on a rod to a wrapping section in which three wrapping rollers engage a web of paper and wrap the paper about the stack. Crimping hooks fold over the extending ends of the wrapper and the completed roll is discharged. The width of the track and discharge chute are adjustable for different denominations of coins. One side of the adjustable track and chute is formed on a plate which is pivotally mounted at the rear of the frame of the machine. The other side of the track and chute if formed on a plate which slides over the first plate and moves parallel to it. Adjustment is accomplished relative to a side frame so that the center of the discharge chute is always at the center of the stacking tube. If the stack sensor determines that an improper stack has been formed, the stacking tube is moved laterally and is opened to empty its contents into a reject chute.
