Abstract
A dual delivery mechanism for a coin dispenser providing the ability to deliver coins or tokens to coin cups on both sides of a coin/token dispensing machine has a moveable ramp connected to a transfer lever. The position of the ramp is controlled by a double-acting solenoid that moves a single solenoid plunger connected to the transfer lever. The dual delivery mechanism is mounted in the coin dispenser chassis so that the ramp is positioned beneath the chute into which coins fall when they are ejected from the coin canister. The double-acting solenoid may be controlled by a separate PCB located in the coin canister chassis to which the main microcomputer of the coin dispenser transmits the signal to indicating which direction the coins should be dispensed. Upon receiving the signal, the PCB generates a pulse to the appropriate drive solenoid consisting of an initial short, high voltage part that initiates motion, followed by a longer, low voltage part that maintains ramp position during coin ejection. Energization of one of the sides of the double-acting solenoid causes the solenoid to retract, pulling the lever arm and pivoting the moveable ramp to the appropriate side.
