Abstract

An induction system is disclosed for filtering the induction of objects to a plurality of object processing systems. The induction system includes an evaluation means for evaluating at least one characteristic of an object, and routing means for routing the object in one of a plurality of directions responsive to the evaluated characteristic, at least one of the plurality of directions leading to a selected one of the plurality of object processing systems.

First claim

What is claimed is:

1. An induction system for filtering the induction of objects to a plurality of object processing systems, said induction system comprising:
evaluation means for evaluating at least one characteristic of an object, wherein the evaluation means includes a conveyor section that comprises a plurality of transport rollers and at least one elevated roller that rotates faster than the plurality of transport rollers; and
routing means for routing the object in one of a plurality of directions responsive to the evaluated characteristic, at least one of the plurality of directions leading to a selected one of the plurality of object processing systems.

2. The induction system as claimed in claim 1 , wherein the evaluation means determines any of a weight, mass, volume or density of the object.

3. The induction system as claimed in claim 1 , wherein the at least one elevated roller is mounted on one of a load cell or a force torque sensor.

4. The induction system as claimed in claim 1 , wherein the plurality of directions includes a path that leads to a processing station for processing non-rigid objects.

5. The induction system as claimed in claim 1 , wherein the routing means includes a source configured to apply any of a vacuum and a forced air to the object.

6. The induction system as claimed in claim 1 , wherein the routing means includes a chute having at least one set of bomb-bay doors that are actuated for dropping the object from the chute to a lower conveyor section.

7. The induction system as claimed in claim 1 , wherein the routing means includes a three-way conveyor for moving the object in one of three selectable directions.

8. The induction system as claimed in claim 1 , wherein the plurality of directions lead to the plurality of object processing stations in series.

9. The induction system as claimed in claim 1 , wherein the plurality of directions lead to the plurality of object processing stations in parallel.

10. The induction system as claimed in claim 1 , wherein the plurality of object processing stations include automated object processing stations and manual object processing stations.

11. A method of distributing induction of objects to an object processing system including a plurality of object processing stations, said method comprising:
transporting an object along a conveyor section that comprises a plurality of transport rollers and a perturbation roller mounted to a sensor, the perturbation roller being configured to rotate faster than the plurality of transport rollers;
determining at least one characteristic of the object using the sensor as the object travels over the perturbation roller; and
routing the object in one of a plurality of directions responsive to the at least one characteristic of the object, at least one of the plurality of directions leading to a selected one of a plurality of object processing stations.

12. The method as claimed in claim 11 , wherein determining at least one characteristic of the object includes determining any of a weight, mass, volume or density of the object.

13. The method as claimed in claim 12 , wherein the sensor comprises at least one load cell.

14. The method as claimed in claim 11 , wherein the plurality of directions includes a path that leads to a processing station for processing non-rigid objects.

15. The method as claimed in claim 11 , wherein the object is routed in one of the plurality of directions by applying any of a vacuum and a forced air to the object.

16. The method as claimed in claim 11 , wherein the object is routed in one of the plurality of directions by dropping the object from a chute through a pair of bomb-bay doors.

17. The method as claimed in claim 11 , wherein the object is routed in one of the plurality of directions by using a three-way conveyor to move the object in one of three selectable directions.

18. The method as claimed in claim 11 , wherein the plurality of object processing stations include automated object processing stations and manual object processing stations.

19. The method as claimed in claim 11 , wherein the sensor is one of a load cell and a force torque sensor.

20. The method as claimed in claim 11 , wherein the perturbation roller is elevated partially above the plurality of transport rollers.

21. The method as claimed in claim 11 , wherein the perturbation roller has a larger diameter than the plurality of transport rollers.

22. The method as claimed in claim 11 , further comprising determining that the object is balanced on the perturbation roller, and wherein the at least one characteristic of the object is determined using the sensor in response to determining that the object is balanced on the perturbation roller.

23. An object induction system, comprising:
a first conveyor section that comprises a plurality of transport rollers and at least one perturbation roller that rotates faster than the plurality of transport rollers, wherein the at least one perturbation roller is mounted to a sensor configured to determine at least one characteristic of an object travelling over the first conveyor section; and
a second conveyor section configured to route the object in one of a plurality of directions responsive to the at least one characteristic of the object.

24. The object induction system as claimed in claim 23 , wherein the sensor is one of a load cell and a force torque sensor.

25. The object induction system as claimed in claim 23 , wherein the perturbation roller is elevated partially above the plurality of transport rollers.

26. The object induction system as claimed in claim 23 , wherein the perturbation roller has a larger diameter than the plurality of transport rollers.

27. The object induction system as claimed in claim 23 , further comprising a plurality of perception units directed towards the first conveyor section,
the plurality of perception units being configured to determine when the object is balanced on the perturbation roller, and wherein the sensor determines the at least one characteristic of the object in response to the plurality of perception unit determining that the object is balanced on the perturbation roller.

28. The object induction system as claimed in claim 23 , wherein the at least one determined characteristic of the object is any of a weight, mass, volume or density of the object.

29. The induction system as claimed in claim 28 , wherein the sensor is one of a load cell or a force torque sensor.

30. The object induction system as claimed in claim 23 , wherein the second conveyor section includes a three-way conveyor for routing the object in the one of the plurality of directions.

31. The object induction system as claimed in claim 23 , wherein the second conveying section includes a source configured to apply any of a vacuum and a forced air to the object for moving the object from the second conveying section to the one of the plurality of directions.

32. The object induction system as claimed in claim 23 , wherein the second conveying section includes a chute having at least one set of bomb-bay doors that are actuated for dropping the object from the chute to a lower conveyor section.
