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.

First claim

What is claimed is:

1. A method of distributing objects to one of a plurality of receiving units, said method comprising:
providing a vacuum from a vacuum opening of a vacuum source above the conveyor section;
providing forced air from an air blower below the conveyor section;
lifting an object off of the conveyor section into contact with the vacuum opening by the vacuum provided by the vacuum source and the forced air provided by the air blower;
holding the object with the vacuum provided by the vacuum source from above the conveyor;
obtaining perception data regarding the object when lifted off of the conveyor section;
controlling the vacuum provided by the vacuum source to maintain the object above the conveyor section; and
moving the vacuum opening with respect to the conveyor section while maintaining the vacuum to position the object above a destination location responsive to the perception data.

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

3. The method as claimed in claim 1 , wherein the 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 conveyor section.

5. The method as claimed in claim 1 , wherein the method further includes dynamically adjusting the vacuum provided by the vacuum source using an adjustable vacuum control system responsive to the perception data.

6. The method as claimed in claim 1 , wherein the method further includes adjusting a flow of the forced air from the air blower below the conveyor section using an adjustable forced air control system responsive to the perception data.

7. The method as claimed in claim 1 , wherein moving the vacuum opening with respect to the conveyor section includes moving the vacuum source along a rail.

8. A distribution system for providing objects into one of a plurality of receiving systems, said distribution system comprising:
a conveyor section for conveying a plurality of objects;
a perception system directed toward an area above the conveyor section and for providing perception data;
a vacuum system including a vacuum source that provides a vacuum through a vacuum opening above the conveyor section and a forced air system including a first air blower below the conveyor section that provides a flow of forced air up through the conveyor section that lift an object among the plurality of objects off of the conveyor section;
a control system for dynamically adjusting a vacuum pressure provided by the vacuum source at the vacuum opening and dynamically adjusting the flow of forced air provided by the forced air system to lift the object off of the conveyor section; and
a vacuum transfer system for moving the vacuum opening and the object to one of a plurality of receiving systems responsive to the perception data.

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

10. The distribution system as claimed in claim 8 , wherein the forced air system further includes a second air blower that provides a further flow of forced air over the conveyor section that urges an object off of the conveyor section to one of the plurality of receiving units.

11. The distribution system as claimed in claim 10 , wherein the plurality of receiving units include any of an adjacent conveyor, a chute or a mobile carrier.

12. The distribution system as claimed in claim 8 , wherein the vacuum transfer system further includes a rail along which the vacuum source is moved with respect to the conveyor section.

13. A distribution system for providing objects into one of a plurality of receiving systems, said distribution system comprising:
a conveyor section for conveying a plurality of objects;
a perception system directed toward the plurality of objects and for providing perception data;
a vacuum system including a vacuum source that provides a vacuum through a vacuum opening above the conveyor section and a forced air system including a first air blower below the conveyor section that provides a flow of forced air up through the conveyor section;
a control system for adjusting the vacuum provided by the vacuum source and the flow of forced air provided by the first air blower to lift an object among the plurality of objects off of the conveyor section into contact with the vacuum opening of the vacuum source; and
a transfer system for moving the vacuum opening and the object to above one of a plurality of receiving systems responsive to the perception data, wherein the object is dropped into the one of the plurality of receiving units by ceasing the vacuum provided by the vacuum source.

14. The distribution system as claimed in claim 13 , wherein the conveyor section includes a mesh material that includes mesh openings.

15. The distribution system as claimed in claim 13 , wherein the forced air system further includes a second air blower that provides a further flow of forced air over the conveyor section that urges another object among the plurality of objects off of the conveyor section to one of the plurality of receiving units.

16. The distribution system as claimed in claim 13 , wherein the vacuum transfer system further includes a rail along which the vacuum source is moved with respect to the conveyor section.

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