Abstract
An air conveyor system has a blower in communication with a plenum. The blower provides air to the plenum to move the objects with respect to the plenum. The air conveyor system includes a plurality of dampers disposed at predetermined locations along the plenum with the dampers being normally open. A sensor device senses the location where the objects have accumulated with respect to the plenum. Furthermore, the air conveyor system includes a closing device for closing the damper which is at the location where the objects have accumulated with respect to the plenum. The closing of the damper is based upon the sensed accumulated location. The system includes a variable speed blower for providing air to move objects with respect to the plenum. The objects are either in an accumulated or unaccumulated state with respect to the plenum. A velocity measuring device measures the velocity of the objects, and an adjustment device which is connected to the velocity measuring device adjusts the speed of the blower to a predetermined speed based upon the velocity of the unaccumulated objects.
