Abstract

This invention relates to a power-driven conveyor system for transporting and accumulating a plurality of items along a path of movement from a source to a destination. The system includes a horizontally oriented section for accumulating the items along the path and an apparatus for transporting the items therealong. The apparatus may be either a plurality of parallel, spaced-apart endless belts or a plurality of conveying sections interconnected together to form an endless carrier. Each section of the carrier may constitute itself a device for directly carrying one of the items. The invention provides an effective horizontal accumulator for items on a production or an assembly line operating at a relatively high speed. The accumulator operates on the FIFO principle so that, upon a malfunction of either upstream or downstream equipment, dated or otherwise sequentially marked items are stored in such a manner that the first item into the system is the first item to come out. Additionally, the invention provides an effective horizontal accumulator for items with irregular shapes or of fragile nature. Production line backpressure does not exist so that the risk of locking or wedging of items being transported is reduced. There is also a reduced risk of breakage or quality damage. Additionally, the invention provides an effective horizontal accumulator for items requiring a particular orientation as delivered by the source. The items are maintained and delivered according to the needs at the destination.
