Abstract
An actuator (42) moves a nozzle (16) between vertical operating positions to accommodate the changing longitudinal configuration of a vehicle (18) and a rotary drive (46) rotates the nozzle (16) about a nozzle axis to efficiently direct air against the contour of the vehicle (18). The assembly is characterized by a first sensor (50) disposed upstream of the nozzle (16) for detecting the presence of a vehicle and a second sensor (52) disposed between the first sensor (50) and the nozzle (16) for detecting the contour of a vehicle and a controller (54) for generating a blower start signal in response to the first sensor (50) and for generating an actuator signal to energize the vertical actuator (42) to move the nozzle (16) vertically between operating positions. A third sensor (56) is disposed adjacent the nozzle (16) to sense the front and rear of a vehicle for generating a rotary signal to energize a rotary drive (46) for rotating the nozzle (16) about the nozzle axis. A processor (70) adjusts the blower operational time in response to the number of vehicles per predetermined time period to optimize the number of blower starts per hour.
