Automatic Mail Tray Loader and Unloader

The system as depicted schematically herein operates as follows:

A letter mail tray 1, having a bottom comprised of longitudinal slots, is first moved by a conveyor, not shown, into an unloading station, and then clamped at its ends by clamps 4. Actuator 10 operates elevating mechanism 3 which passes through the longitudinal tray slots, and raises mail pieces 5 upwardly from the tray into the constraint of stack pusher 7. The stacked mail pieces 5 are moved as a body into induction station 9. The elevating mechanism 3 then returns to its home position below tray 1, and clamps 4 are released.

Tray 1 is then automatically conveyed away for reloading so that a mail laden tray replaces the emptied one.

Loading mail into an empty mail tray 1 is the inverse of the process just described. Stack length compensator 8 is adjusted so that pusher 7 accumulates a body of mail pieces 5 from induction station 9. Next, pusher 7 moves the mail pieces 5 as a body onto the elevating mechanism 3. The elevating mechanism 3 on returning to its home position below tray 1, deposits the body of mail into tray 1 which is automatically conveyed away and an emptied mail tray replaces it.
