Abstract
A system for sorting items such as fruit includes a movable transport belt for each serial stream. The transport belt has first and second portions that are spaced a distance apart for receiving and carrying items previously singulated into serial streams. The first and second portions of the transport belts gradually diverge to slowly lower the items onto movable carriers which are introduced directly below the diverging sections of the transport belt portions. As a result, the fruit experiences little vertical drop and need not be accelerated by the carrier cups. Fruit or other items being gradually released from the belts can be transported at the same speed as the carrier cups to avoid the bruising effect caused by the rear portions of the carrier cups striking the items as they are dropped in. In addition, the transport belt can be arranged to carry the items through a sorter section without guides. As a result, a larger portion of the item to be sorted can be exposed to a sorting device to more accurately complete the sorting process.
