Abstract
An air flow control mechanism for a multi-channel air conveyor enables the flow rate of air ejected from air outlet orifices of inner channels of the multi-channel air conveyor to be adjusted without changing the flow of air ejected from air outlet orifices of the outer pair of air conveyor channels of the multi-channel air conveyor.
Claims21
An air conveyor with an adjustable air flow control comprising:
- an air plenum having a longitudinal length defining a conveyor path of the air conveyor and having a lateral width, the air plenum having a surface with a plurality of air inlet orifices;
- and
- an air control device mounted on the air plenum surface for movement of the air control device between first and second positions of the air control device relative to the air plenum surface, the air control device having a plurality of throttle openings and the throttle openings are arranged on the air control device where the throttle openings are aligned with the air inlet orifices when the air control device is moved to its first position and the throttle openings are not aligned with the air inlet orifices when the air control device is moved to its second position.
An air conveyor with an adjustable air flow control comprising:
- a plurality of longitudinal channels that are arranged laterally side-by-side, each channel having an inverted U-shape defined by a top wall and a pair of laterally spaced side walls below the top wall;
- pairs of mutually opposed, laterally spaced flanges projecting from each pair of side walls into each channel, the pairs of flanges defining longitudinal conveyor path slots therebetween;
- pairs of air ducts extending through each pair of side walls between air inlet orifices of the ducts and air outlet orifices of the ducts that open into the channels defined by the pair of side walls;
- and an air control device mounted over at least some of the air inlet orifices for movement of the air control device between first and second positions of the air control device relative to the air inlet orifices, the air control device having a plurality of throttle openings and the throttle openings are arranged on the air control device where the throttle openings are aligned with air inlet orifices of the air conveyor when the air control device is moved to its first position and the throttle openings are not aligned with the air inlet orifices when the air control device is moved to its second position.
