Dual lane air transport assembly

摘要

A pneumatic conveying apparatus for container bodies having neck rings. The apparatus comprises a plurality of pairs of laterally spaced neck tracks, each pair defining an elongated slot therebetween for slidably supporting container bodies by their neck rings and a plurality of inverted, U-shaped, interior channel members, each extending upwardly from one of the pairs of neck tracks spanning the slot and extending longitudinally substantially the length of the slot and having a cross sectional area sufficient to receive the portions of the container bodies above their neck rings, each interior channel member having a top wall and side walls with air directing louvers formed therein to provide a driving force for the container bodies. The apparatus further comprises an inverted U-shaped, exterior channel member extending upwardly from the neck tracks enclosing the plurality of interior channel members and extending longitudinally substantially the length of the slots, and pneumatic means to introduce air under pressure to the space between the exterior channel member and one of the interior channel members whereby such space may constitute a plenum chamber and direct a flow of air within the interior chamber in a direction dictated by the angle of the louvers for conveying container bodies supported by their necks on the neck tracks in the direction of the air flow.
