The present invention relates to a tray transfer system (TTS). This system is designed to automatically transfer trays of mail between dollies and conveyor belts. The TTS is an efficient method for shipping, moving, storing, loading, and unloading mail trays. It allows mail-processing centers to physically and temporally separate the process of sorting mail and the process of moving mail into automation compatible trays (ACT).

Tray transfer system

An automated flats handling system is provided that includes mail shuttles, a tray unloading section, a quality control area, a shuttle tilter, a shuttle return section and a stacker/loader. The tray unloading section has a conveyor and unloads mail from a standard tray into one of the shuttles. The quality control area also has a conveyor and facilitates grooming the mail in the shuttle. The shuttle tilter tilts each shuttle prior to unloading the mail from the shuttle. The shuttle return section also has a conveyor and returns the shuttles to the tray unloading section. The stacker/loader cooperates with the shuttle tilter and unloads the mail from the shuttles, creates a mail stack from the unloaded mail, and loads a portion of the mail stack into an automation compatible tray.
