ABSTRACT:
An automatic control system for carwash installations is constructed with electromechanical logic elements--relay-operated switching devices and timer-controlled switches--combined into an Input Control Unit and into a plurality of Program Control Units. Each vehicle entering the carwash is automatically assigned to one of the Program Control Units which performs the sequence of operations, including optional operations such as the application of hot wax to the vehicle, in the proper sequence as the automobile travels along the conveyer of the installation. No controllers or sensors are required to be installed along the conveyor, and the conveyor itself is automatically stopped when there are no automobiles moving along the conveyor, or when there is a possibility of a collision between successive vehicles leaving the conveyor system.
