The present invention provides for a continuous flow transfer system designed to transfer the contents of a mail tray into a cartridge for subsequent processing and then, after processing, to transfer the contents of the cartridge back into a mail tray without disrupting the facing or orientation of each piece of mail. The continuous flow transfer system comprises both a cartridge loader and a cartridge unloader, both of which have a tray section, a transfer conveyor and a cartridge section. The tray section, or infeed section, of the cartridge loader is designed to deliver filled mail trays to the transfer section of the loader. At the transfer section, the contents of each mail tray are deposited into an intermediate container that is affixed to the transfer section. The transfer section then delivers the contents of the intermediate container into empty cartridges being fed onto the cartridge section, or discharge section, of the loader. Once filled, each cartridge is then transported away from the cartridge loader for processing, where the mail is removed from each container, processed and place back into a cartridge. After processing, the filled cartridges are then delivered to the cartridge section, or infeed section, of the cartridge unloader. Similar to the loader, the contents of each cartridge are transferred into an intermediate container affixed to the transfer section. The transfer section then delivers the contents of the intermediate container to the mail section, or discharge section, of the unloader, where the mail is transferred back into mail trays. The filled mail trays are then ready for delivery.

Continuous flow transfer system

The apparatus is used to remove a generally rectangular container from an unloading device that places the container in a predetermined position. The container has a bottom surface, upstanding sidewalls and forward and rear endwalls. The apparatus includes a base portion for supporting the apparatus and a container removing arm pivotally attached to the base portion configured to releasably engage the container and remove the container from the unloading device. Also included are container engaging clamps operatively connected to the container removing arm arranged to contact and releasably engage at least one of the bottom surface, the upstanding sidewalls, the forward endwall, and the rear endwall of the container. A powered assembly pivotally displaces the container removing arm when the clamps releasably engage the container. A controller is operatively coupled to the powered assembly to selectively control forward and backward pivoting of the arm. The controller is also operatively coupled to the container engaging clamps to selectively control engagement of the clamps such that backward pivoting of the arm while the clamps engage the container facilitates removal of the container from the unloading device when the arm is pivoted in a backward direction.
