A continuous loop sorter is comprised of a rail or track configured in an endless loop on which individual carriages ride at speeds of up to 590 feet per minute. The carriages are connected together to form a chain, which is used to drive them along the track. Specific to the Tilt Tray sorter, each carriage is topped by a tray, commonly made of wood or plastic, that can be individually actuated to tilt to either one or both sides. The item on the tray is then deposited by gravity onto either a chute or a takeaway conveyor.
Items to be sorted can be manually deposited onto the trays by personnel, automatically inducted onto the trays by induction conveyor, or a combination of the two methods. Regardless of which method is used, the item placed onto the tray is tracked by controls software and is transferred to its correct location. This arrangement allows for sortation of up to 40,000 items per hour.
Tilt tray sorters are very versatile in that they can be used with virtually any type of packaging. Whether the item to be transferred is packaged in a carton, bag, or tote, if the item fits on the tray, it can be sorted efficiently, including very small or oddly shaped items.
In comparison with other sortation technologies, a tilt tray sorter can be easily reconfigured or expanded with minimal difficulty. This technology has been widely and successfully used in many different industries, just a few of which are apparel, postal, publishing, and pharmaceutical.
