Abstract

A distribution system for use in an induction system with an object processing system. The distribution system provides dissimilar objects into one of a plurality of receiving units. The distribution system includes an air intake system with an opening that is a fixed distance from a conveyor section, said air intake system aiding in moving an object on the conveyor section from the conveyor section to one of a plurality of adjacent transport units.

Claims (33)

1. A method of distributing objects to one of a plurality of receiving units, said method comprising:

providing forced air upward through an air-permeable conveyor section from an air blower positioned below the air-permeable conveyor section;

providing a vacuum from a vacuum opening of a vacuum source positioned on a rail above the air-permeable conveyor section and opposite the air blower;

lifting an object off the air-permeable conveyor section into contact with the vacuum opening of the vacuum source using the forced air and the vacuum;

moving the vacuum source along the rail with respect to the conveyor section while maintaining the vacuum to position the object above a destination location; and

ceasing the vacuum so that the object falls from the vacuum source onto the destination location.

2. The method as claimed in claim 1 , wherein the air-permeable conveyor section includes a conveyor with a plurality of openings in the conveyor.

3. The method as claimed in claim 1 , wherein the air-permeable conveyor section is formed of a mesh material.

4. The method as claimed in claim 1 , wherein the method further includes dynamically adjusting the vacuum provided by the vacuum source to accommodate a variety of objects presented to the air-permeable conveyor section.

5. The method as claimed in claim 1 , wherein the method further includes providing perception data from a perception unit that is directed toward the air-permeable conveyor section.

6. The method as claimed in claim 1 , wherein the method further includes adjusting a flow rate of the forced air from the air blower using an adjustable forced air control system.

7. A distribution system for providing objects into one of a plurality of receiving units, said distribution system comprising:

an air-permeable conveyor section;

an air intake system including a vacuum source positioned on at least one side of the conveyor section for providing a vacuum; and

an air transfer system including an upward forced air system and a side forced air system,

the upward forced air system being positioned below the conveyor section for providing a flow of air up through the conveyor section, and the side forced air system being positioned on at least one side of the conveyor section that opposes the vacuum source for providing a flow of air across the conveyor section;

wherein the vacuum source, the upward forced air system and the side force air system cooperate to move an object off the conveyor section to one of the plurality of receiving units adjacent to the conveyor section.

8. The distribution system as claimed in claim 7 , wherein the air-permeable conveyor section includes a mesh material that includes mesh openings.

9. The distribution system as claimed in claim 7 , wherein the distribution system further includes a forced air control system for dynamically adjusting the air transfer system.

10. The distribution system as claimed in claim 7 , wherein the distribution system further includes a vacuum control system for dynamically adjusting the vacuum source.

11. The distribution system as claimed in claim 7 , wherein the distribution system further includes a perception unit that is directed toward the conveyor section for providing perception data of the object.

12. The distribution system as claimed in claim 7 , wherein the distribution system further includes a rail along which the vacuum source is moved with respect to the conveyor section.

13. The distribution system as claimed in claim 7 , wherein the plurality of receiving units include any of an adjacent conveyor, a chute or a mobile carrier.

14. A distribution system for providing objects into one of a plurality of receiving units, said distribution system comprising:

an air-permeable conveyor section;

an air intake system including a vacuum source positioned on at least one side of the conveyor section for providing a vacuum;

an air transfer system including a plurality of forced air blowers, at least one of the plurality of forced air blowers directing forced air up through the conveyor section and at least one other of the plurality of forced air blowers directing forced air across the conveyor section towards the vacuum source, wherein the vacuum provided by the vacuum source and the flow of air provided by the plurality of forced air blowers cause an object on the conveyor section to move off of the conveyor section to one of the plurality of receiving units; and

a detection system for providing detection data regarding the object on the conveyor section, and for adjusting the flow of air to facilitate moving the object on the conveyor section off of the conveyor section to one of the plurality of receiving units.

15. The distribution system as claimed in claim 14 , wherein the conveyor section includes a mesh material that includes mesh openings.

16. The distribution system as claimed in claim 14 , wherein the distribution system further includes a forced air control system for dynamically adjusting the plurality of forced air blowers included in the air transfer system.

17. The distribution system as claimed in claim 14 , wherein the distribution system further includes a vacuum control system for dynamically adjusting the vacuum provided by the vacuum source.

18. The distribution system as claimed in claim 14 , wherein the distribution system further includes a rail along which the vacuum source is moved with respect to the conveyor section.

19. The distribution system as claimed in claim 14 , wherein the plurality of receiving units include any of an adjacent conveyor, a chute or a mobile carrier.
