Coin Release Actuator

Client:
Park Ur Self System Inc., Petaluma, California.

Client's Request:
To design a coin release mechanism for parking meters that would use an electrical signal to activate the mechanical coin release arm of a standard coin changer.

Overview of KLN's Contribution:
Electronic and mechanical design of the coin changer, as well as batch production of this electro-mechanical assembly.

Detailed Outcome:
A sturdy sheet metal chassis supports a rocker arm which is activated by an electric motor via a robust cam follower. An electric interface board receives the activation signal from the computer, senses the position of the cam and controls the current through the motor.
