Abstract
An air conveyor moves light objects from one location to another and may also act as an accumulator for storing objects transported thereon. The conveyor has an elongated primary plenum and one or more elongated body members disposed over and in communication with the primary plenum through openings in the bottom wall of each body member. Each body member has a generally planar top deck disposed thereover. Each body member defines a secondary plenum between the top deck and the bottom wall of the body member. The top deck has a plurality of directional orifices formed therein. Blowers in communication with the primary plenum supply air to the secondary plenum through the primary plenum. The air from the secondary plenum is delivered through the directional orifices in the top deck and creates a current, or cushion, of air on which the objects move. Manually adjustable dampers are provided for restricting the size of the openings and regulating the air pressure between the primary plenum and the secondary plenums. The conveyor may also have guide rails for controlling object movement.
