Abstract

An overhead warehousing system for use in a warehouse having a ceiling and a plurality of storage racks supported by the floor of a warehouse includes a plurality of tramways affixed to the ceiling, each tramway associated with at least one storage rack. At least one robotic module is engaged upon each tramway and translatable thereon. Each robotic module includes a powered carrier engaging the tramway for translating the robotic module therealong and a utility head connected to the powered carrier. The utility head is vertically positionable with respect to the powered carrier and is rotatable about a vertical axis. At least one gripper head is horizontally translatable from and rotatable relative to the utility head and includes a plurality of gripper fingers for grasping a parcel. A plurality of drones may be incorporated by the system to perform some of the parcel transporting operations of the robotic modules.

Claims

a powered carrier engaging said tramway for translating said robotic module therealong,

a utility head operatively mounted to said powered carrier, said utility head vertically positionable with respect to said powered carrier and angularly rotatable about a vertical axis with respect to said powered carrier, and

at least one gripper head operatively mounted to said utility head and horizontally translatable from and angularly rotatable relative to said utility head, said gripper head including a plurality of gripper fingers being operable to respectively grasp and drop a parcel.

2. The system as recited in claim 1 wherein each of said tramways comprises dual spaced-apart tracks.

3. The system as recited in claim 2 wherein each of said powered carriers has a pair of guides each for receiving one of said tramway tracks.

4. The system as recited in claim 1 further comprising a communication subsystem in communication with said at least one robotic module for controlling translation of said at least one robotic module on said each tramway between a designated warehouse receiving location, a designated parcel retrieval location and a designated parcel drop location.

5. The system as recited in claim 4 wherein said communication subsystem is also in communication with said at least one robotic module for controlling vertical positioning of said utility head relative to said powered carrier of said robotic module and horizontal translation and angular rotation of said gripper head relative to said utility head for grasping and dropping the parcel.

6. The system as recited in claim 1 further comprising a plurality of drones each having an operatively mounted utility head, and a gripper head operatively mounted to said utility head and vertically translatable from and angularly rotatable relative to said utility head, said gripper head having a plurality of gripper fingers being operable to respectively grasp and drop a parcel.

7. The system as recited in claim 6 further comprising a communication subsystem in communication with each of said drones for plotting a trajectory and controlling flying of said each drone along said trajectory between a designated docking station and a designated warehouse receiving location, a designated parcel retrieval location and a designated parcel drop location.

8. The system as recited in claim 7 wherein said communication subsystem is also in communication with each of said drones for controlling vertical translation and angular rotation of said gripper head relative to said utility head, and operation of said gripping figures to respectively grasp and drop the parcel.

9. An overhead warehousing system for use in a warehouse having a ceiling and a plurality of storage racks supported by the floor of the warehouse, said overhead warehousing system comprising:

a plurality of tramways affixed to the ceiling of the warehouse, each said tramway being associated with at least one of the storage racks;

at least one robotic module engaged upon each said tramway and translatable thereon, said robotic module comprising;

a powered carrier engaging said tramway for translating said robotic module therealong,

a utility head connected to said powered carrier, said utility head vertically positionable with respect to said utility head and rotatable about a vertical axis, and

at least one gripper head horizontally translatable from said utility head, said gripper head including a plurality of gripper fingers for grasping a parcel;

a communication subsystem in communication with said at least one robotic module for controlling translation of said at least one robotic module on said each tramway between a designated warehouse receiving location, a designated parcel retrieval location and a designated parcel drop location; and

a plurality of drones each having an operatively mounted utility head and a gripper head operatively mounted to said utility head and vertically translatable from and angularly rotatable relative to said utility head, said gripper head having a plurality of gripper fingers being operable to respectively grasp and drop a parcel,

wherein said communication subsystem is also in communication with each of said drones for plotting a trajectory and controlling flying of said each drone along said trajectory between a designated docking station and a designated warehouse receiving location, a designated parcel retrieval location and a designated parcel drop location.

10. The system as recited in claim 9 wherein each of said tramways comprises dual spaced-apart tracks.

11. The system as recited in claim 10 wherein each of said powered carriers has a pair of guides each for receiving one of said tramway tracks.

12. The system as recited in claim 9 wherein said communication subsystem is also in communication with said at least one robotic module for controlling vertical positioning of said utility head relative to said powered carrier of said robotic module and horizontal translation and angular rotation of said gripper head relative to said utility head for grasping and dropping the parcel.

13. The system as recited in claim 12 wherein said communication subsystem is also in communication with each of said drones for controlling vertical translation and angular rotation of said gripper head relative to said utility head, and operation of said gripping figures to respectively grasp and drop the parcel.

14. The system as recited in claim 9 wherein said communication subsystem is also in communication with each of said drones for controlling vertical translation and angular rotation of said gripper head relative to said utility head, and operation of said gripping figures to respectively grasp and drop the parcel.

15. An overhead warehousing method for use in a warehouse having a ceiling and a plurality of storage racks supported by the floor of the warehouse, said overhead warehousing method comprising the steps of:

providing a plurality of tramways and robotic modules, each of said tramways being affixed to the ceiling of the warehouse and associated with at least one of the storage racks, at least one of said robotic modules being engaged upon each of said tramways and translatable thereon, each of said robotic modules having a utility head operatively mounting a gripper head and a plurality of gripper fingers on said gripper head;

translating said at least one robotic module along a respective one of said tramways between a designated parcel retrieval location and a designated parcel drop location; and

horizontally translating and angularly rotating said gripper head relative to said utility head on said robotic module and operating said plurality of gripper fingers on said gripper head to respectively grasp and drop a parcel.

16. The method as recited in claim 15 further comprising operating a communication subsystem in communication with said at least one robotic module to control said translating said at least one robotic module on said each tramway between the designated parcel retrieval location and the designated parcel drop location.
