Abstract

Palletizing systems and methods increasing the efficiency at which pallets of mixed products are built. The systems and methods include a pallet building module for receiving customer orders and generating pallet building instructions for arranging the products on the pallets, among other functions. The pallet building module is in communication with a number of robot cells that include source products and pallet building robots for building pallets based upon instructions generated by the pallet building module. The system includes other modules for system control including conveyor controllers, forklift controllers, and automatic guided vehicle controllers, among other controllers. Methods for building pallets of mixed product from source products within more than one robot cell.

Claims

1. A palletizing system, comprising:

(a) a pallet building module for receiving a customer order for products and generating pallet building instructions from the order;

(b) multiple robot cells in communication with the pallet building module and adapted to carry out the pallet building instructions, the robot cells comprising a plurality of source products and a robot for retrieving the products from among the source products and arranging the products on at least one pallet, and wherein each of the at least one pallets is assembled by more than one robot cell; and

(c) at least one automatic guided vehicle in communication with the pallet building module and operable for transporting the at least one pallet between robot cells and within the palletizing system.

2. The palletizing system according to claim 1, wherein each of the source products are labeled with a product identifier and each of the at least one pallets include more than one product identifier.

3. The palletizing system according to claim 1, wherein the pallet building instructions comprise assigning family codes to the products, sorting the products by the family codes, sorting the products into layers and determining the physical configuration of each layer of the at least one pallet.

4. The palletizing system according to claim 1, wherein the pallet building instructions comprise comparing product layer height to a maximum pallet layer height.

5. The palletizing system according to claim 1, wherein the number of pallets required for the customer order is determined by the pallet building module.

6. The palletizing system according to claim 1, wherein the pallet building module processes pallet build additions and deletions based on changes to the order from a customer and source product inventory.

7. The palletizing system according to claim 1, wherein the products are arranged on the at least one pallet into product layers that share a common product identifier and package layers that have mixed product identifiers.

8. The palletizing system according to claim 1, wherein the pallet building module determines the physical coordinates and orientation for each of the products to be placed on the at least one pallet.

9. The palletizing system according to claim 1, wherein each of the at least one pallets are collectively assembled by the multiple robot cells.

10. A method for building a pallet of mixed products, comprising:

(a) providing a pallet building module for receiving a customer order for products and generating instructions for arranging the products on the pallet;

(b) building a first portion of the pallet at a first robot cell comprising first source products and a first robot including end-of-arm tooling;

(c) transporting the pallet to a second robot cell using an automatic guided vehicle; and

(d) building a second portion of the pallet at the second robot cell comprising second source products and a second robot including end-of-arm tooling;

wherein the instructions are communicated from the pallet building module to the first and the second robot cells.

11. The method according to claim 10, wherein the automatic guided vehicle is controlled by the pallet building module.

12. The method according to claim 10, wherein the first and the second source products are labeled with a product identifier.

13. The method according to claim 10, wherein the instructions comprise assigning family codes to the products, sorting the products by the family codes, sorting the products into layers and determining the physical configuration of each layer on the pallet.

14. The method according to claim 10, wherein the pallet building instructions comprise comparing product layer height to a maximum pallet layer height.

15. The method according to claim 10, wherein the pallet building module processes pallet build additions and deletions based on changes to the order from a customer and source product inventory.

16. The method according to claim 10, wherein the products are arranged on the pallet into product layers that share a common product identifier and package layers that have mixed product identifiers.

17. The method according to claim 10, wherein the pallet building module determines the physical coordinates and orientation for each of the products to be placed on the pallet.

18. A method for building a pallet of mixed products, comprising:

(a) providing a pallet building module for generating instructions for dividing the task of building a complete pallet including the mixed products into more than one robot cell;

(b) building the pallet with the more than one robot cell; and

(c) transporting the pallet between robot cells using an automatic guided vehicle.

19. The method according to claim 18, further comprising the step of providing source products to the more than one robot cell prior to building the pallet.
