ABSTRACT:
A controlled speed single file conveyor selectively conveys a first set of upright cylindrical articles having a smaller diameter and a second set of upright cylindrical articles having a larger diameter in single file along a deck plate, having inboard and outboard edges, from an upstream location to a downstream location. A first set of a plurality of longitudinal, parallel rows of smaller inboard louvers and a second set of a plurality of longitudinal, parallel rows of larger outboard louvers extend through the deck plate at a shallow angle and are angled so that the air discharged therefrom has a force vector component toward the inboard side edge and a force vector component in the downstream direction. A vertical wall, parallel to the inboard edge, is vertically and laterally adjustable above the upper surface of the deck plate and has a lower edge above the deck plate forming a variable exhaust opening therebetween to control the exhausting of air therethrough to control the downstream speed of the articles. The wall is selectively movable in the inboard and outboard directions to be positioned adjacent the smaller inboard and the larger outboard louvers to selectively convey the larger diameter and the smaller diameter articles, respectively.
