Abstract

An object processing system is disclosed for unloading objects from a trailer of a tractor trailer. The object processing system includes an engagement system including a truck entry portion for entering the trailer and for indiscriminately engaging unidentified objects within the trailer, and a conveyance system for conveying objects engaged by the engagement system toward an unloading portion of the trailer.

First claim

What is claimed is:

1. An object processing system for unloading objects from a trailer of a tractor trailer, said object processing system comprising:
an engagement system including a movable unloading structure having a drive system for entering the trailer and a cleated conveyor supported by the movable unloading structure for indiscriminately engaging unidentified objects within the trailer, said engagement system further including guides configured along the cleated conveyor to urge engaged objects toward the center of the cleated conveyor; and
a conveyance system including an extendable chute coupled to the movable unloading structure for conveying objects engaged by the cleated conveyor of the engagement system out of the trailer, wherein the extendable chute extends in response to the unloading structure moving into the trailer.

2. The system as claimed in claim 1 , wherein the unloading structure of the engagement system includes a wheeled structure that moves into the trailer, the wheeled structure supporting the cleated conveyor.

3. The system as claimed in claim 1 , wherein the system further includes at least one perception unit, wherein the at least one perception unit includes any of a camera and a scanner.

4. The system as claimed in claim 1 , wherein the extendable chute conveys the engaged objects out of the trailer and into at least one bin.

5. The system as claimed in claim 1 , comprising a further conveyance system for transporting the objects from the extendable chute toward a distribution location.

6. The system as claimed in claim 5 , wherein the further conveyance system includes at least one other chute.

7. The system as claimed in claim 5 , wherein the distribution location includes an object processing system inside a further trailer.

8. The system as claimed in claim 7 , wherein the further conveyance system includes an in-feed conveyor that provides the objects to the further trailer.

9. The system as claimed in claim 7 , wherein the object processing system provides a plurality of output stations within the further trailer where processed objects are provided.

10. An automated method of unloading objects from a trailer of a tractor trailer, comprising:
moving an unloading structure into the trailer, wherein the unloading structure includes a cleated conveyor and an extendable chute;
extending the extendable chute in response to the unloading structure moving into the trailer;
indiscriminately engaging unidentified objects within the trailer using the cleated conveyor with the aid of a plurality of guides;
conveying the engaged objects from the cleated conveyor out of the trailer through the extended chute; and
transporting the objects toward a distribution location.

11. The method as claimed in claim 10 , wherein the unloading structure is a wheeled structure that moves into the trailer.

12. The method as claimed in claim 10 , further comprising receiving perception data from at least one perception unit, wherein the at least one perception unit includes any of a camera and a scanner.

13. The method as claimed in claim 10 , wherein the distribution location includes an object processing system inside a further trailer.

14. The method as claimed in claim 13 , wherein transporting the objects toward the destination location includes transporting the objects into the further trailer using a further conveyor positioned at an end of the extendable chute outside the trailer.

15. The method as claimed in claim 10 , wherein the distribution location includes at least one bin.

16. The method as claimed in claim 10 , wherein the distribution location includes an object processing system inside a further trailer.

17. The method as claimed in claim 16 , wherein the method further includes providing the objects to the further trailer along an in-feed conveyor.

18. The method as claimed in claim 16 , wherein the method further includes providing a plurality of output stations within the further trailer where processed objects are provided.

19. An object processing system for unloading objects from a trailer of a tractor trailer, said object processing system comprising:
an engagement system including a movable unloading structure having a drive system for entering the trailer and a cleated conveyor supported by the movable unloading structure, said engagement system further including at least one front guide configured to urge objects near a side wall of the trailer toward the cleated conveyor for indiscriminately engaging unidentified objects within the trailer; and
a conveyance system including an extendable chute coupled to the movable unloading structure for receiving and conveying objects engaged by the cleated conveyor of the engagement system out of the trailer, wherein the extendable chute extends in response to the unloading structure moving into the trailer.

20. The system as claimed in claim 19 , wherein the unloading structure of the engagement system includes a wheeled structure that moves into the trailer, the wheeled structure supporting the cleated conveyor.

21. The system as claimed in claim 19 , wherein the system further includes at least one perception unit, wherein the at least one perception unit includes any of a camera and a scanner.

22. The system as claimed in claim 19 , wherein the extendable chute conveys the engaged objects out of the trailer and into at least one bin.

23. The system as claimed in claim 19 , comprising a further conveyance system for transporting the objects from the extendable chute toward a distribution location.

24. The system as claimed in claim 23 , wherein the further conveyance system includes at least one other chute.

25. The system as claimed in claim 23 , wherein the distribution location includes an object processing system inside a further trailer.

26. The system as claimed in claim 25 , wherein the further conveyance system includes an in-feed conveyor that provides the objects to the further trailer.

27. The system as claimed in claim 25 , wherein the object processing system provides a plurality of output stations within the further trailer where processed objects are provided.
