Abstract: A wide variety of product types, sizes and shapes are sorted into designated destination bins or other outputs utilizing a computer controlled transport path that includes an infeed section and a pinch roller diverting section. The infeed section receives a singulated stream of products to be sorted, optically scans each product for a destination code and transports the products downstream to the diverting section. The diverting section consists of a series of individually and selectively controlled roller pairs in combination with a number of diverting gates. Each roller pair includes an upper foam covered pinch roller and a lower friction drive roller oriented such that products moving downstream pass between each roller pair until diverted from the transport path. An array of photoelectric detectors provide product position information to identify and track product movement through the apparatus.

Abstract: A singulated stream of products comprised of both single and overlapping products is transported through a scanning zone along a transport path. Each single or overlapping product defines a shadow on the transport path that is analyzed to determine the presence of product multiples in the product shadow by measuring the width and length of the product shadow. If the length of the product shadow exceeds by more than a predetermined amount the average length of previously measured shadows having a similar width, the shadow likely contains two or more overlapping products. As the product shadow moves through the scanning zone, each product included therein is scanned for affixed bar codes by a plurality of bar code scanners. If two different bar codes or two identical bar codes from mutually exclusive scanners are recorded for a single product shadow, then the shadow likely contains two or more overlapping products.
