Tire dressing apparatus

摘要

The tire dressing apparatus is controlled by a carwash controller operated typically by an attendant at the carwash. The width of a vehicle entering the carwash is determined mechanically by an index arm, the identification of the vehicle selected for application of the tire dressing fluid to the vehicle's tires, and a programmable logic controller controls a spraying sequence by controlling the time intervals between the activation of solenoids controlling fluid release through nozzles during each vehicle tire dressing cycle. The programmable logic controller includes sufficient memory to keep track of the vehicle in the carwash que or in the carwash in the event of some mechanical or electrical interruptions to the carwash operation. A unique nozzle design has been provided to obtain the desired fluid distribution and coverage on the vehicle tires.
