Abstract

A distribution system is disclosed for use with an induction system with an object processing system. The distribution system provides distribution of dissimilar objects into one of a plurality of receiving units. The distribution system includes an urging system for urging an object on a conveyor from the conveyor to a chute that includes at least one actuatable door for selectively dropping the object through the at least one actuable door, said chute leading to a first receiving station with a second receiving station being positioned below the at least one actuable door.

First claim

What is claimed is:

1. A distribution system for providing dissimilar objects into one of a plurality of receiving stations, said distribution system comprising an urging system for urging an object on a conveyor from the conveyor to a chute in a generally horizontal direction, wherein the urging system includes an air intake system that provides a negative air flow to urge the object from the conveyor to the chute, and wherein the urging system further includes a first forced air system that opposes the air intake system and directs a first positive air flow at the object in the generally horizontal direction to urge the object from the conveyor to the chute.

2. The distribution system as claimed in claim 1 , wherein the urging system further includes a second forced air system that directs a second positive air flow in a generally vertical direction to facilitate urging the object from the conveyor.

3. The distribution system as claimed in claim 2 , wherein the conveyor includes an air-permeable conveyor section proximate the second forced air system.

4. The distribution system as claimed in claim 1 , wherein the chute leads to a further conveyor.

5. The distribution system as claimed in claim 1 , wherein the chute leads to a mobile carrier.

6. The distribution system as claimed in claim 1 , wherein the first forced air system is reversible in flow direction.

7. The distribution system as claimed in claim 1 , wherein the air intake system is reversible in flow direction.

8. The distribution system as claimed in claim 1 , wherein the distribution system further includes at least one perception system in communication with a vacuum control processer coupled to a vacuum control system for adjusting a rate of flow provided by the air intake system.

9. The distribution system as claimed in claim 1 , wherein the distribution system further includes at least one perception system in communication with a blower control processer coupled to a blower control system for adjusting a rate of flow provided by the first forced air system.

10. A distribution system for providing dissimilar objects into one of a plurality of receiving stations, said distribution system comprising an urging system for urging an object on a conveyor from the conveyor to a chute in a generally horizontal direction, wherein the urging system includes an air intake system that provides a negative air flow to urge the object from the conveyor to the chute, and wherein the urging system further includes a forced air system that opposes the air intake system and directs a positive air flow at the object in a generally vertical direction through the conveyor to urge the object from the conveyor to the chute.

11. The distribution system as claimed in claim 10 , wherein the conveyor includes an air-permeable conveyor section proximate the forced air system.

12. The distribution system as claimed in claim 10 , wherein the chute leads to a further conveyor.

13. The distribution system as claimed in claim 10 , wherein the chute leads to a mobile carrier.

14. The distribution system as claimed in claim 10 , wherein the air intake system is reversible in flow direction.

15. The distribution system as claimed in claim 10 , wherein the distribution system further includes at least one perception system in communication with a vacuum control processer coupled to a vacuum control system for adjusting a rate of flow provided by the air intake system.

16. The distribution system as claimed in claim 10 , wherein the distribution system further includes at least one perception system in communication with a blower control processer coupled to a blower control system for adjusting a rate of flow provided by the first forced air system.

17. A method of distributing objects, comprising:
moving a plurality of dissimilar objects on a conveyor toward a conveyor processing area;
applying forced air from a first forced air system to the conveyor processing area;
applying a vacuum pressure from an air intake system to the conveyor processing area;
urging a first object from the conveyor processing area to a first chute on a first side of the conveyor processing conveyor with the forced air and the vacuum pressure; and
permitting a second object from the conveyor processing area to remain on the conveyor processing area while maintaining the forced air and the vacuum pressure at the conveyor processing area.

18. The method as claimed in claim 17 , wherein the conveyor includes an air-permeable conveyor section proximate the first forced air system.

19. The method as claimed in claim 17 , wherein the first chute leads to a further conveyor.

20. The method as claimed in claim 17 , wherein the first chute leads to a mobile carrier.

21. The method as claimed in claim 17 , wherein the first forced air system is reversible in flow direction.

22. The method as claimed in claim 17 , wherein the air intake system is reversible in flow direction.

23. The method as claimed in claim 17 , wherein the method further includes adjusting a rate of flow provided by the air intake system by a vacuum control system responsive to a vacuum control processor in communication with at least one perception system.

24. The method as claimed in claim 17 , wherein the method further includes adjusting a rate of flow provided by the air intake system by a blower control system responsive to a blower control processor in communication with at least one perception system.

25. The method as claimed in claim 17 , wherein the method further includes reversing the directions of flow of the forced air and the vacuum pressure to urge a third object from the conveyor processing area to a second chute on a second side of the conveyor that is opposite the first side of the conveyor processing area with the reversed flow forced air and the reversed flow vacuum pressure.
