There have also been a number of developments in tilt-tray design in recent years.

Tilt-tray conveyor systems, which carry goods in individual trays that tip and discharge their contents at appropriate outfeed points, are also suitable for handling a wide range of products.

Because they use gravity to discharge their contents, tilt-tray conveyors are best suited to handling non-fragile, irregular products such as loose items of clothing and many other products normally considered non-conveyable.

Throughputs of around 12,000 items per hour can be achieved and this figure can be increased further still by using multiple inducts and a variety of discharge chute configurations.

Both crossbelt and tilt-tray sorters allow recirculation of goods, providing some on-line storage and enabling goods to be staged or sorted in particular sequences.
