Abstract

Embodiments relate to a cart assembly having a lower deck, an upper deck, and a gantry. The lower deck has designated areas for empty containers and for filled containers. The gantry includes a gripper system configured to grab at least one container from the empty-container staging area and transport it to a receiving site, where a crop harvesting apparatus deposits a crop in the container. Once the container is filled, the gantry moves the filled container so as to position it within a filled-container staging area of the lower deck. The gripper system then releases the container. The process is continued while the cart assembly is transported throughout a crop harvesting facility to harvest crops.

Claims (38)

1. An automated packing cart assembly, comprising:

a cart including a lower deck, vertical supports, and an upper deck forming a space within which containers are held, the lower deck including an empty-container staging area and a filled-container staging area;

a gantry secured to the upper deck, the gantry including a gripper system configured to releasably grab a container;

a control module configured to:

cause the gripper system to retrieve the container from the empty-container staging area and transport it to a receiving site to receive an object in the container;

determine when the container is filled; and

transport the filled container to the filled-container staging area,

wherein the control module is configured to actuate the vertical motion servo and/or the horizontal motion servo in a repeated manner to cause the gripper system to oscillate in a vertical and/or horizontal movement while the gripper system has a container and the container is positioned in the receiving site.

2. The automated packing cart assembly of claim 1 , wherein the object is a crop.

3. The automated packing cart assembly of claim 2 , further comprising:

a crop harvesting apparatus configured to retrieve crops from plants and direct them to the container that is within the receiving site.

4. The automated packing cart assembly of claim 1 , further comprising:

wheels attached to the cart.

5. The automated packing cart assembly of claim 4 , further comprising a means of propulsion.

6. The automated packing cart assembly of claim 4 , wherein the wheels are flanged track wheels.

7. The automated packing cart assembly of claim 1 , wherein the lower deck, the vertical supports, and the upper deck are constructed of connectable subparts.

8. The automated packing cart assembly of claim 1 , wherein the gantry includes a vertical motion servo and a horizontal motion servo, each in electro-mechanical association with the gripper system via the control module to cause the gripper system to move in a vertical motion and/or a horizontal motion.

9. The automated packing cart assembly of claim 1 , wherein:

the gripper system includes a first gripper arm and a second gripper arm configured to secure the container between each other.

10. The automated packing cart assembly of claim 1 , wherein the gripper system includes a load cell configured to measure the weight of the container when the container is grabbed by the gripper system and hoisted so as to be suspended by the gripper system.

11. The automated packing cart assembly of claim 9 , wherein the gripper system includes a positon sensor to assess the position of the gripper system and/or the first and second gripper arms relative to the container.

12. An automated packing cart assembly, comprising:

a cart including a lower deck, vertical supports, and an upper deck forming a space within which containers are held, the lower deck including an empty-container staging area and a filled-container staging area;

a gantry secured to the upper deck, the gantry including a gripper system configured to releasably grab a container;

a control module configured to:

cause the gripper system to retrieve the container from the empty-container staging area and transport it to a receiving site to receive an object in the container;

determine when the container is filled; and

transport the filled container to the filled-container staging area,

wherein the gantry includes a vertical motion servo and a horizontal motion servo, each in electro-mechanical association with the gripper system via the control module to cause the gripper system to move in a vertical motion and/or a horizontal motion, and

wherein the control module is programmed to execute a homing procedure, in which, upon the automated packing cart assembly experiencing a reset, a system fault, or is powered-on after being powered-off, each of the vertical motion servo and the horizontal motion servo is moved to an initializing point.

13. The automated packing cart assembly of claim 12 , wherein the initializing point is the receiving site.

14. The automated packing cart assembly of claim 12 , wherein the homing procedure includes, as the initializing point, the first griper arm and the second gripper arm being moved away from each other to generate a space between each other that is wider than a width of the container.

15. The automated packing cart assembly of claim 8 , wherein the gripper system includes a positon sensor to determine a vertical position and/or a horizontal position of the griper system relative to the lower deck and/or the upper deck.

16. The automated packing cart assembly of claim 10 , wherein the control module is programmed to execute a weighing procedure that assesses the weight measured by the load cell to determine whether enough objects have been received by the container, and designates the container as filled based on the assessment.

17. The automated packing cart assembly of claim 16 , wherein the weighing procedure uses a threshold weight value that, when reached, causes the control module to designate the container as being filled.

18. The automated packing cart assembly of claim 17 , wherein the threshold weight value for one type of object differs from the threshold weight for another type of object.

19. The automated packing cart assembly of claim 12 , wherein the control module is configured to actuate the vertical motion servo and/or the horizontal motion servo in a repeated manner to cause the gripper system to oscillate in a vertical and/or horizontal movement while the gripper system has a container and the container is positioned in the receiving site.

20. The automated packing cart assembly of claim 12 , wherein the gripper system includes a load cell configured to measure the weight of the container when the container is grabbed by the gripper system and hoisted so as to be suspended by the gripper system.
