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. A distribution system comprising:
an air-permeable conveyor section that is driven around at least one vacuum roller;
the vacuum roller being provided at a free end of the air-permeable conveyor section and including openings through which a vacuum pressure is applied to a plurality of dissimilar objects at the free end of the air-permeable conveyor section;
a perception system for providing monitoring data regarding actions of the plurality of dissimilar objects as the plurality of dissimilar objects are dropped from the free end of the air-permeable conveyor section; and
a controller for controlling any of a rotational speed of the at least one vacuum roller and the vacuum pressure within the at least one vacuum roller responsive to the monitoring data for providing that the plurality of dissimilar objects each travel a selected distance around the vacuum roller before falling from the free end of the air-permeable conveyor section.

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

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

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

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

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

8. The distribution system as claimed in claim 4 , wherein the distribution system includes three receiving units.

9. The distribution system as claimed in claim 1 , wherein the at least one vacuum roller is actively powered to rotate.

10. The distribution system as claimed in claim 1 , wherein the at least one vacuum roller is a passive roller.

11. The distribution system as claimed in claim 1 , wherein the distribution system further includes a selective diverting system that selectively diverts objects to selectively provide the plurality of dissimilar objects to the free end of the air-permeable conveyor section.

12. The distribution system as claimed in claim 11 , wherein the selective diverting system includes a bi-directional conveyor section.

13. The distribution system as claimed in claim 11 , wherein the selective diverting system includes a weight sensing conveyor section.

14. A distribution system comprising:
a porous conveyor section;
a vacuum roller over which the porous conveyor section travels, the vacuum roller being provided at a free end of the porous conveyor section and including openings through which a vacuum pressure is applied to a plurality of dissimilar objects at the free end of the porous conveyor section;
a perception system for providing monitoring data regarding actions of the plurality of dissimilar objects as the plurality of dissimilar objects are moved over the free end of the porous conveyor section; and
a controller for controlling any of a rotational speed of the vacuum roller and the vacuum pressure within the vacuum roller responsive to the monitoring data for providing that the plurality of dissimilar objects each travel a selected distance around the vacuum roller before falling from the free end of the porous conveyor section.

15. The distribution system as claimed in claim 14 , wherein the porous conveyor section includes a conveyor material with a plurality of openings defined therein.

16. The distribution system as claimed in claim 15 , wherein the conveyor material is a mesh material.

17. The distribution system as claimed in claim 14 , wherein the distribution system further includes a plurality of receiving units arranged below the free end of the porous conveyor section.

18. The distribution system as claimed in claim 17 , wherein the plurality of receiving units include at least one mobile carrier.

19. The distribution system as claimed in claim 17 , wherein the plurality of receiving units include at least one chute.

20. The distribution system as claimed in claim 17 , wherein the plurality of receiving units include at least one conveyor.

21. The distribution system as claimed in claim 17 , wherein the distribution system includes three receiving units.

22. The distribution system as claimed in claim 14 , wherein the vacuum roller is actively powered to rotate.

23. The distribution system as claimed in claim 14 , where in the vacuum roller is a passive roller.

24. The distribution system as claimed in claim 14 , wherein the distribution system further includes a selective diverting system that selectively diverts objects to selectively provide the plurality of dissimilar objects to the free end of the porous conveyor section.

25. The distribution system as claimed in claim 24 , wherein the selective diverting system includes a bi-directional conveyor section.

26. The distribution system as claimed in claim 24 , wherein the selective diverting system includes a weight sensing conveyor section.

27. A method of distributing a plurality of dissimilar objects, said method comprising:
providing an air-permeable conveyor section that travels around at least one vacuum roller, the at least one vacuum roller being provided at a free end of the air-permeable conveyor section and including openings through which a vacuum pressure is applied to a plurality of dissimilar objects at the free end of the air-permeable conveyor section;
providing monitoring data regarding actions of the plurality of dissimilar objects as the plurality of dissimilar objects are dropped from the free end of the air-permeable conveyor section; and
controlling any of a rotational speed of the at least one vacuum roller and the vacuum pressure within the at least one vacuum roller responsive to the monitoring data for providing that the plurality of dissimilar objects each travel a selected distance around the at least one vacuum roller before falling from the free end of the air-permeable conveyor section.

28. The method as claimed in claim 27 , wherein the air-permeable conveyor section includes a conveyor material with a plurality of openings defined therein and wherein the conveyor material is a mesh material.

29. The method as claimed in claim 27 , wherein the method further includes providing a plurality of receiving units arranged below the free end of the air-permeable conveyor section.

30. The method as claimed in claim 29 , wherein the plurality of receiving units include at least one mobile carrier.

31. The method as claimed in claim 27 , wherein the plurality of receiving units include at least one chute.

32. The method as claimed in claim 27 , wherein the plurality of receiving units include at least one conveyor.

33. The method as claimed in claim 27 , wherein the at least one vacuum roller is actively powered to rotate.

34. The method as claimed in claim 27 , where in the at least one vacuum roller is a passive roller.
