ABSTRACT:
A conveyor system for uniformly distributing flat articles such as packaged documents at a pick-up location, without allowing them to bunch together. The articles are dropped to land on the surface of a slide and descend to the pick-up location. A feed conveyor delivers the articles to a feed end in the vicinity of the slide. A conveyor section is arranged to pivot about an axis near its downstream end. A drive arrangement swings the conveyor section between a first position where its upstream end confronts the feed end of the feed conveyor to receive articles and convey them to its downstream end, and a second position where its upstream end is raised a certain height above the feed end of the feed conveyor. Thus, when the pivoting section is at the first position, articles delivered by the feed conveyor are then conveyed by the pivoting section and drop to land on one portion of the slide. When the pivoting section is at the second position, articles drop directly from the feed conveyor to land on a different portion of the slide. Additional pivoting conveyor sections may be arranged in tanden, and their relative pivoting movement suitably controlled, so that articles are evenly distributed across the breadth of the slide.
