Abstract
A typing off-loading and article sorting system to automatically separate different parcel types includes an feed conveyor, receiving conveyor, sorting conveyor, cameras and photoelectric eye. The overhead cameras detect the item size and whether it is cubic in nature and type and size of its footprint. An in-line slide sorter having alternating conveyor rollers and pop-up belts pass through to, or divert articles from, a downstream conveyor. The vision based system may also be used to detect space between articles and insert articles in the unoccupied space.
