Abstract: Features for loading, transporting and unloading of items are disclosed. Systems, devices and methods for such operations using a tray are described. In some embodiments, a tray having a moveable bottom allows for switching between a configuration for loading and unloading items in and out of the tray and a configuration for transportation of items inside the tray. The trays may also be stacked, for transportation of multiple trays at once, and nested, for saving space when storing the trays. In some embodiments, the trays may be used in conjunction with loading and unloading systems.

Abstract: Sorting systems and methods for large quantities of items in industrial processes are described. The systems, devices and methods are for receiving, sorting and removing items dynamically. A first group of items, such as letters or other mail pieces, are injected by a belt into a pocket to a form a first stack, and a progressive displacement divider with amplified output for a given input is extended near the first stack. The divider allows for a second group of items to either be injected to form a second stack behind the divider, or to be diverted and injected into another pocket. The first stack can be removed while the second group is being injected.
