Abstract

In an induction system for use with an object processing system, a distribution system is disclosed for providing dissimilar objects into one of a plurality of receiving units. The distribution system includes a conveyor section that travels over a vacuum roller, and the plurality of receiving units arranged generally below the vacuum roller such that an object with a mass will fall toward one of the plurality of receiving units based on both the object's mass and a vacuum force applied to the object through the conveyor section.

First claim

What is claimed is:

1. An object processing system comprising:
an input conveyance system for providing a singulated stream of objects;
a weight sensing conveyor section for receiving each of the singulated stream of objects and for providing weight data regarding each object of the singulated stream of objects;
a diverter for selectively diverting each of the singulated stream of objects responsive to the weight data associated with each object of the singulated stream of objects;
a plurality of paths extending from the diverter along which each of the plurality of objects may be selectively diverted by the diverter in response to the weight data; and
a vacuum roller positioned along at least one of the plurality of paths, the vacuum roller including openings through which a vacuum force is applied through an air-permeable conveyor section to each of a subset of the singulated stream of objects causing each of the subset of the singulated stream of objects to fall from the vacuum roller at any of a plurality of rotational positions of the vacuum roller dependent on the weight of each of the subset of the singulated stream of objects.

2. The object processing system as claimed in claim 1 , wherein the air-permeable conveyor section includes a conveyor material with a plurality of openings defined therein.

3. The object processing system as claimed in claim 2 , wherein the conveyor material is a mesh material.

4. The object processing system as claimed in claim 1 , further comprising a plurality of receiving units arranged below a free end of the air-permeable conveyor section.

5. The object processing system as claimed in claim 4 , wherein the plurality of receiving units includes at least one mobile carrier.

6. The object processing system as claimed in claim 4 , wherein the plurality of receiving units includes at least one chute.

7. The object processing system as claimed in claim 4 , wherein the plurality of receiving units includes at least one conveyor.

8. The object processing system as claimed in claim 4 , wherein the plurality of receiving units includes three receiving units.

9. The object processing system as claimed in claim 1 , wherein the vacuum roller is actively powered to rotate.

10. The object processing system as claimed in claim 1 , wherein the vacuum roller is a passive roller.

11. An object processing system comprising:
an input conveyance system for providing a singulated stream of objects;
a perception system for providing perception data regarding each of the singulated stream of objects, said perception data including data regarding any of a weight, size, packaging or identity of each of the singulated stream of objects;
a diverter for selectively diverting each of the singulated stream of objects responsive to the perception data associated with each object of the singulated stream of objects;
a plurality of paths extending from the diverter along which each of the singulated stream of objects may be selectively diverted by the diverter in response to the perception data; and
a vacuum roller positioned along at least one of the plurality of paths, the vacuum roller including openings through which a vacuum force is applied through an air-permeable conveyor section to each of a subset of the singulated stream of objects causing each of the subset of the singulated stream of objects to fall from the vacuum roller at any of a plurality of rotational positions of the vacuum roller dependent on the weight of each of the subset of the singulated stream of objects.

12. The object processing system as claimed in claim 11 , wherein the air-permeable conveyor section includes a conveyor material with a plurality of openings defined therein.

13. The object processing system as claimed in claim 12 , wherein the conveyor material is a mesh material.

14. The object processing system as claimed in claim 11 , further comprising a plurality of receiving units arranged below a free end of the air-permeable conveyor section.

15. The object processing system as claimed in claim 14 , wherein the plurality of receiving units includes at least one mobile carrier.

16. The object processing system as claimed in claim 14 , wherein the plurality of receiving units includes at least one chute.

17. The object processing system as claimed in claim 14 , wherein the plurality of receiving units includes at least one conveyor.

18. The object processing system as claimed in claim 14 , wherein the plurality of receiving units includes three receiving units.

19. The object processing system as claimed in claim 11 , wherein the vacuum roller is actively powered to rotate.

20. The object processing system as claimed in claim 11 , wherein the vacuum roller is a passive roller.

21. An object processing system comprising:
an input conveyance system for providing a singulated stream of objects;
a perturbation roller over which each of the singulated stream of objects may pass exhibiting a variety of responses, each of the variety of responses providing perturbation roller data specific to each of the singulated stream of objects;
a diverter for selectively diverting each of the singulated stream of objects responsive to the perturbation roller data associated with each object of the singulated stream of objects;
a plurality of paths extending from the diverter along which each of the singulated of objects may be selectively diverted by the diverter in response to the perturbation roller data; and
a vacuum roller positioned along at least one of the plurality of paths, the vacuum roller including openings through which a vacuum force is applied through an air-permeable conveyor section to each of a subset of the singulated stream of objects causing each of the subset of the singulated stream of objects to fall from the vacuum roller at any of a plurality of rotational positions of the vacuum roller dependent on a weight of each of the subset of the singulated stream of objects.

22. The object processing system as claimed in claim 21 , wherein the air-permeable conveyor section includes a conveyor material with a plurality of openings defined therein.

23. The object processing system as claimed in claim 22 , wherein the conveyor material is a mesh material.

24. The object processing system as claimed in claim 21 , further comprising a plurality of receiving units arranged below a free end of the air-permeable conveyor section.

25. The object processing system as claimed in claim 24 , wherein the plurality of receiving units includes at least one mobile carrier.

26. The object processing system as claimed in claim 24 , wherein the plurality of receiving units includes at least one chute.

27. The object processing system as claimed in claim 24 , wherein the plurality of receiving units includes at least one conveyor.

28. The object processing system as claimed in claim 24 , wherein the plurality of receiving units includes three receiving units.

29. The object processing system as claimed in claim 21 , wherein the vacuum roller is actively powered to rotate.

30. The object processing system as claimed in claim 21 , wherein the vacuum roller is a passive roller.
