Abstract

An apparatus, a method and a system for cutting or trimming a portion of an article using a jet stream provided by a nozzle tip. The apparatus includes a drive unit configured to provide a rotational force and a cam assembly connectable to the drive unit and configured to move the nozzle tip to cut the portion of the article. The apparatus includes a conveyor belt that has a void area and a cutting area, and a cam that includes at least one track to drive a frame assembly.

Claims

1. An apparatus for cutting or trimming a portion of an article to a predetermined size, including trimming at least one end of the article or removing a defect from the article using a jet stream provided by a nozzle tip to optimize packed out yield, the apparatus comprising:

a drive unit configured to provide a rotational force; and

a cam assembly connectable to the drive unit and configured to move the nozzle tip to cut the portion of the article according to predetermined criteria,

wherein the article.

2. The apparatus according to claim 1, further comprising:

a conveyor belt comprising a void area and a cutting area.

3. The apparatus according to claim 1, further comprising:

a cam comprising a track; and

a frame assembly engageable with the track.

4. The apparatus according to claim 1, wherein the cam assembly is offset and stacked into a six-by-five array.

5. The apparatus according to claim 4, further comprising:

a pair of the six-by-five array configured for each of two sides of a forty-four lane ADR system.

6. The apparatus according to claim 3, wherein the cam comprises a second track.

7. The apparatus according to claim 3, wherein the frame assembly comprises:

a nozzle support member configured to hold the nozzle tip; and

a front cam follower support comprising a cam follower configured to engage said track.

8. The apparatus according to claim 7, further comprising:

a rotator configured to connect the nozzle support member to the front cam follower support.

9. The apparatus according to claim 6, wherein the frame assembly comprises:

a nozzle support member-configured to hold the nozzle tip;

a front cam follower support comprising a cam follower configured to engage said track; and

a rear cam follower support comprising a cam follower configured to engage said track.

10. The apparatus according to claim 9, wherein the frame assembly further comprises:

a brace comprising a first end configured to pivotally connect to the front cam follower support and a second end configured to pivotally connect to the nozzle support member.

11. The apparatus according to claim 10, wherein the frame assembly further comprises:

a guide rod having a longitudinal axis, wherein

the guide rod guides the front cam follower support or the rear cam follower support in the longitudinal direction, and

prevents motion of the front cam follower support or the rear cam follower support in a direction perpendicular to the longitudinal direction.

12. The apparatus according to claim 11, wherein the frame assembly further comprises:

an other guide rod having the longitudinal axis, wherein

the other guide rod guides the front cam follower support or the rear cam follower support in the longitudinal direction, and

prevents motion of the front cam follower support or the rear cam follower support in a direction perpendicular to the longitudinal direction.

13. The apparatus according to claim 1, further comprising:

an inspector configured to detect and determine attributes of the article and generate a control signal based on predetermined criteria,

wherein the cam assembly is further configured to move the nozzle tip to cut the portion of the article based on the control signal.

14. The apparatus according to claim 13, wherein the cam assembly comprises a dual track cam that is configured to move the nozzle tip across a full lane during a 180°

rotation.

15. The apparatus according to claim 1, wherein the nozzle tip is moved to cut the portion of the article in at least one of a substantially 90°

angle, a substantially oblique angle, or a substantially variable angle.

16. The apparatus according to claim 1, wherein the nozzle tip is moved to cut the portion of the article in a French fancy style cut.

17. The apparatus according to claim 1, wherein the nozzle tip is moved to cut the portion of the article in synchronism with a conveyor belt speed.

18. The apparatus according to claim 1, wherein the nozzle tip is moved to cut the portion of the article at a speed that is different from a conveyor belt speed.

19. The apparatus according to claim 1, wherein the article comprises:

a green bean;

a wax bean;

or

a pea pod.

20. The apparatus according to claim 1, wherein the drive unit comprises a speed regulated linear actuator, chain and sprocket with clutch mechanism, or cylinder.

21. The apparatus according to claim 2, wherein the conveyor belt comprises a stainless steel mesh belt.

22. The apparatus according to claim 1, further comprising:

a vacuum configured to hold down the article at a force multiple times the weight of the article.

23. The apparatus according to claim 22, wherein the vacuum comprises:

a fluid deceleration trough configured to collect the jet stream.

33. An article processed by the apparatus according to claim 1.

24. A method for cutting or trimming a portion of an article using a jet stream, the method comprising:

detecting an article in a field of view;

determining attributes of the article; and

cutting the portion of the article based on the determined attributes.

25. The method according to claim 24, further comprising:

determining location data for the attributes of the article; and

generating control data based on predetermined criteria.

26. The method according to claim 24, further comprising:

determining if an end of the article is in the field of view; and

determining location data for the end.

27. The method according to claim 25, wherein the predetermined criteria comprise:

a length of the article;

a width of the article;

a color of the article;

a brightness of the article;

or

a lightness of the article.

28. The method according to claim 27, wherein the cutting the portion of the article based on the determined attributes comprises:

trimming one end of the article; and

cutting the remaining portion of the article in half.

29. The method according to claim 28, wherein the cutting the portion of the article based on the determined attributes further comprises:

driving a dual track cam to move the jet stream from a first position to a second position.

30. The method according to claim 29, wherein the first and second positions are located over a void area of a conveyor belt.

31. The method according to claim 29, wherein driving the dual track cam to move the jet stream from the first position to the second position comprises rotating the dual track cam through substantially 180°

.
