ABSTRACT:
A product conveying and accumulation system and method employs a primary product transporting conveyor with accumulation and re-circulating sections. The conveyor is configured to receive products from an upstream destination and discharge products to a downstream destination. A second conveyor, operable at a considerable slower speed than the first conveyor, is located in the same transverse plane as and is aligned adjacent to the first conveyor. Both conveyors travel in the same direction at the adjacent alignment. As products are discharged from the system, a wall of product is formed on the slower moving conveyor. As a result, products on the inner lane of the faster moving conveyor which would otherwise tend to move inward towards the discharge point, causing product turbulence and disruption, are urged back onto the inner lane by the product wall and then smoothly discharged from the system to the downstream destination. The use of this slower conveyor increases product stability by substantially eliminating product turbulence caused by the product bunching and nesting which normally occurs at the product discharge point. A substantially increased rate of product outfeed results.
