Abstract

A method for automated handling, positioning and orienting of an ear of corn includes methods for altering a portion of an ear of corn. Optionally included are one or more stations for automatically processing, testing, sampling and preparing the ear of corn for processing, testing or sampling and an automated transport means for automatically moving ears of corn from station to station using alterations made to the ear of corn.

Claims

1. A method for preparing an ear of corn for being handled, positioned and oriented by automated means, the method comprising:

providing a station for altering an ear of corn;

auto-centering the ear of corn at the station;

retaining the ear of corn in a desired position and orientation at the station for altering the ear of corn; and

altering the ear of corn comprising;

a. removing tissue from the ear of corn to provide for automated handling, positioning and orienting of the ear of corn;

or

b. appending material to the ear of corn to provide for automated handling, positioning and orienting of the ear of corn.

2. The method of claim 1 wherein removing tissue step comprises:

a. scraping tissue from the ear of corn;

b. eroding tissue from the ear of corn;

or

c. cutting tissue from the ear of corn.

3. The method of claim 1 wherein removing tissue step comprises creating a hole in a shank portion of the ear of corn.

4. The method of claim 3 further comprising automated handling, positioning and orienting the ear of corn using the hole.

5. The method of claim 1 wherein the appending material step comprises appending a rigid member to the ear of corn.

6. The method of claim 5 further comprising automated handling, positioning and orienting the ear of corn using the rigid member attached to the ear of corn.

7. The method of claim 1 wherein the step of retaining the ear of corn in the desired position and orientation at the station comprises:

a. exposing a shank portion of the ear of corn to positive pressure;

or

b. exposing an shank portion of the ear of corn to negative pressure.

8. The method of claim 1 in combination with an automated machine for testing, sampling or preparing the ear of corn for testing or sampling.

9. The method of claim 8 further comprising handling, positioning and orienting the ear of corn with the automated machine using:

a. the material appended to the ear of corn;

or

b. the removed tissue portion of the ear of corn.

21. The method of claim 1, wherein auto-centering the ear of corn at the station comprises inserting the ear of corn into a conofrustical recess.

10. A method for preparing an ear of corn for being handled, positioned and oriented by automation, the method comprising:

providing a station having material removal means;

auto-centering the ear of corn at the station;

retaining the ear of corn in a desired position and orientation at the station by holding means; and

autonomously creating a hole in the ear of corn with material removal means to provide for automated handling, positioning and orienting of the ear of corn using the hole.

11. The method of claim 10 further comprising creating the hole in the ear of corn by actuating and advancing:

a. said material removal means into said holding means;

or

b. said holding means into said material removal means.

12. The method of claim 10 wherein the step of creating the hole in the ear of corn with said material removal means comprises:

a. scraping material from the ear of corn;

b. eroding material from the ear of corn;

or

c. cutting material from the ear of corn.

13. The method of claim 10 wherein the step of keeping the ear in the desired position and orientation with said holding means comprises:

gripping the ear of corn pneumatically.

14. The method of claim 10 further comprising detecting presence of the ear of corn at said holding means for controlling operation of said material removal means.

15. The method of claim 10 in combination with an automated machine configured for testing, sampling and preparing the ear of corn for testing and sampling.

16. The method of claim 15 wherein the automated machine comprises a chain-on edge conveyor spindle, each ear of corn being attached to the spindle by impaling the ear of corn on the spindle.

22. The method of claim 10, wherein auto-centering the ear of corn at the station comprises inserting the ear of corn into a conofrustical recess.

17. A method for automated handling, positioning and orienting of an ear of corn by conveyance means in a high-throughput system, the method comprising:

providing a station for altering an ear of corn;

auto-centering the ear of corn at the station;

holding the ear of corn at the station during altering;

altering the ear of corn to have a feature used to secure the ear of corn to said conveyance means; and

handling, positioning and orienting the ear of corn in the high-throughput system using said conveyance means for testing, sampling, processing or preparing the ear of corn for testing, sampling or processing.

18. The method of claim 17 wherein the altering step comprises:

a. creating a cavity in the ear of corn;

b. adding material to the ear of corn;

or

c. appending a feature to the ear of corn.

19. The method of claim 18 wherein said conveyance means is adapted to use the cavity, added material or appended structure to handle, position and orient the ear of corn in the high-throughput system.

20. The method of claim 17 further comprising passing the conveyance means holding said ears of corn through one or more corn testing, sampling, or processing stations within the high-throughput system.

23. The method of claim 17, wherein auto-centering the ear of corn at the station comprises inserting the ear of corn into a conofrustical recess.
