Automated mail tray loading system and method

Presently disclosed embodiments are directed to a system and method for loading mail trays in a sorter without human intervention. Specifically, the disclosed embodiments utilize an automated mail tray having a bottom plate that is selectively moveable between an elevated position and a lowered position. The automated mail tray may be positioned on a shelf under a corresponding output pocket of a mail stacker, and the bottom plate may be elevated to receive mail product transferred from the output pocket to the automated mail tray. After receiving the mail product on the elevated bottom plate, the bottom plate of the mail tray may be lowered so that the mail product is transferred from the output pocket to a position fully situated in the automated mail tray. The mail tray filled with mail product may then be removed from the shelf and replaced with an empty automated mail tray.
