ATR has supplied the USPS with automated robotic unloader systems for palletized USPS mail trays. These machines handle all of the standard mail trays (MM, EMM, SMM) and provide a high volume output of singulated mail trays without the damage typical of "dumpers".
The robotic un-loader cells are high production machines capable of output mail tray streams in excess of 40 trays per minute.
In operation, full pallets are delivered to the cell by forklift, placed in the loading bin, and the shrink-wrap is removed. Active mechanisms straighten the pallet load for robotic unloading. Full pallet layers are unloaded one at a time using a specialized end of arm tool fitted to a high capacity industrial robot. Successive layers of trays are de-scrambled and singulated for induction onto an automated tray line. Two separate pallet loading positions are provided to enable continuous operations so a new pallet can be loaded while the previous pallet is being completed. This unload system can be used for a variety of parcel objects and loading profiles.
