ABSTRACT:
A product aligning system specially adapted for receiving and aligning product items in bulk quantity, includes a hopper for receiving masses of product items in bulk and including a hopper conveyor extending across the bottom of the hopper, a hopper nose conveyor for receiving product items conveyed by the hopper conveyor and extending outwardly from the hopper, and a scale conveyor for receiving items from the hopper nose conveyor. The hopper nose conveyor and scale conveyor each include powered rakes positioned above the item supporting surfaces of those conveyors such that substantially only a single layer of items passes therebeneath. The hopper nose and scale conveyors each include load sensing apparatus which detects an accumulation of product items on those conveyors and signals a computer control which slows the speeds of the hopper and hopper nose conveyors sufficiently to allow the accumulation of products to reduce. The system also includes a product orienting component which includes an array of V-shaped belts positioned in alternating relation with an array of O-ring belts. The O-ring belts are driven at a slower speed than the V-shaped belts, and further, are driven at varying speeds, so that individual product items which bridge between adjacent O-ring belts, or between a V-shaped belt and an adjacent O-ring belt, are rotated as a result of the speed differential to lay substantially in alignment with the V-shaped product supporting belts. Powered rakes are positioned above the V-shaped belts so that substantially only a single layer of aligned product is conveyed from the downstream ends of the belts.
