  • Patent number: 11142413
    Abstract: An autonomous dock station system having an automated material lift truck (AMT), a pallet conveyor, and a facility guidance system can automatically load and/or unload a trailer at a dock station. The autonomous dock station system can coordinate these components according to a workflow procedure. In some embodiments, the workflow procedure can begin with the pallet conveyor supplying a loaded pallet to a specified position. The AMT, initially guided by fixed guidance elements of the facility guidance system, can lift the pallet off the conveyor and transport it to a trailer entrance where the AMT switches from the facility guidance system to a trailer guidance system. The AMT can then carry the pallet to an unloading position, move the pallet to one side of the trailer as needed, unload the pallet and return to the pallet conveyor. The workflow procedure can repeat until the trailer is full.
