Abstract

A cargo loading system comprising a control module for coordinating the transportation of cargo from one area to a trailer according to a stacking pattern and delivery route, an AGV control module for controlling the operation and navigation of at least one AGV, and a user interface for inputting commands and receiving outputs into/from the system. A method for loading cargo comprising the steps of providing a cargo loading control module, providing an AGV control module in communication with the cargo loading control module, providing a user interface, communicating cargo loading tasks to an AGV, and transporting cargo from a production area to a trailer in accordance with a stacking pattern and along a dynamic guide path.

Claims

1. A system for automating cargo loading, comprising:

a cargo loading control module for coordinating the transportation of cargo from a production area onto a trailer positioned within a loading bay along a dynamic guide path and according to a stacking pattern;

at least one automatic guided vehicle comprising a sensor system and a laser guided navigational system; and

an automatic guided vehicle control module in communication with the cargo loading control module and operable for controlling the operation and navigation of the at least one automatic guided vehicle.

2. The system according to claim 1, further comprising a LADAR system for detecting the location of the trailer within the loading bay and detecting cargo present in the trailer.

3. The system according to claim 1, wherein the sensor system scans in three dimensions.

4. The system according to claim 1, wherein the guide path is dynamic and is determined by the physical location of the trailer within the loading bay and cargo present in the trailer.

6. The system according to claim 1, wherein the cargo comprises pallets.

7. The system according to claim 1, wherein the automatic guided vehicle control module includes a software application that communicates with the cargo loading control module to coordinate automatic guided vehicle movement based on signals and signal status interfaced to the automatic guided vehicle control module.

8. The system according to claim 1, wherein the automatic guided vehicle control module includes a graphical user interface that provides real-time status and conditions of the at least one automatic guided vehicle, and displays guide paths and pick-up and delivery stations.

5. The system according to claim l, wherein the cargo loading control module is further operable for generating a stacking pattern, initiating an order, granting the at least one automatic guided vehicle access into the trailer, coordinating movement of the at least one automatic guided vehicle, and modifying the stacking pattern based on operator inputs.

9. A method for loading cargo, comprising:

providing at least one automatic guided vehicle comprising a sensor system and a laser guided navigational system;

providing a cargo loading control module for coordinating the transportation of cargo from a production area to a trailer positioned within a loading bay;

providing an automatic guided vehicle control module in communication with the cargo loading control module and operable for controlling the operation and navigation of the at least one automatic guided vehicle;

communicating transportation tasks to the at least one automatic guided vehicle; and

transporting the cargo from the production area to the trailer along a dynamic vehicle guide path.

10. The method according to claim 9, further comprising:

identifying the position of the trailer within the loading bay with a laser capable of scanning in three dimensions.

11. The method according to claim 9, further comprising:

identifying the existence and position of any previously loaded cargo in the trailer by way of a laser capable of scanning in three dimensions.

12. The method according to claim 9, wherein the dynamic guide path is determined by a vision system and the laser guided navigational system.

13. The method according to claim 9, further comprising:

generating a stacking pattern, initiating an order, granting the at least one automatic guided vehicle access into the trailer, coordinating movement of the at least one automatic guided vehicle, and modifying the stacking pattern based on operator inputs.

14. The method according to claim 9, further comprising:

providing a graphical user interface that provides real-time status and conditions of the at least one automatic guided vehicle, and displays guide paths and pick-up and delivery stations.

15. A method for loading cargo, comprising:

positioning a trailer at a cargo loading bay;

identifying the trailer;

identifying the existence and position of any previously loaded cargo in the trailer with a sensor capable of scanning in three dimensions;

selecting a stacking pattern by which the cargo is stacked in the trailer;

initiating a loading order;

instructing an automatic guided vehicle to pick-up the cargo from a production area and deliver it to the trailer; and

stacking the cargo in accordance with the stacking pattern.

16. The method according to claim 15, further comprising:

granting the automatic guided vehicle access to the trailer;

monitoring guide paths that the automatic guided vehicle follows;

controlling the movement of the automatic guided vehicle; and

returning the automatic guided vehicle to base for recharging between uses.

17. The method according to claim 16, wherein identifying the trailer, selecting the stacking pattern by which the cargo is stacked in the trailer, initiating the loading order, instructing the automatic guided vehicle to pick-up the cargo from the production area and deliver it to the trailer, granting the automatic guided vehicle access to the trailer, monitoring guide paths that the automatic guided vehicle follows, controlling the movement of the automatic guided vehicle, and returning the automatic guided vehicle to the home base for recharging between uses are all controlled by a cargo loading control module.

18. The method according to claim 15, further comprising:

inputting operator commands to manipulate the method.

19. The method according to claim 15, further comprising:

comparing the selected stacking pattern against the trailer identification.

20. The method according to claim 15, further comprising:

satisfying safety and loading bay features prior to loading the trailer.
