Abstract

A system for cutting a three-dimensional portion from a foodstuff includes a conveyor for carrying a foodstuff to be portioned, a scanner located adjacent to the conveyor for scanning the foodstuff, a computer coupled to the scanner for receiving scan information to determine one or more cutting paths for the foodstuff, and a cutter for portioning the foodstuff according to the determined cutting path(s). The computer performs generally four steps: (i) receiving scan information from the scanner; (ii) building a three-dimensional map of the foodstuff based on the received scan information; (iii) fitting at least one desired shape, which is stored in the memory of the computer, onto the built three-dimensional map; and (iv) determining one or more cutting paths for portioning the foodstuff to produce one or more portioned foodstuffs corresponding to the at least one desired shape.

First claim

The invention claimed is:

1. A foodstuff cutting system for cutting one or more desired three-dimensional portions from a foodstuff, comprising:
a scanner for scanning a foodstuff;
a cutter for portioning the foodstuff; and
a computer coupled to the scanner and to the cutter, the computer programmed to perform the steps comprising:
(i) receiving scan information of the foodstuff from the scanner;
(ii) building a three-dimensional map of the foodstuff based on the received scan information of the foodstuff;
(iii) comparing at least one desired three-dimensional shape, which is stored in a memory of the computer, with the generated three-dimensional map of the foodstuff;
(iv) determining one or more cutting paths to be used in portioning the foodstuff into a three-dimensional shape so as to produce one or more three-dimensional portions of the foodstuff, each corresponding to the at least one desired three-dimensional shape; and
(v) sending control signals to the cutter to cause the cutter to portion the foodstuff, according to the one or more cutting paths, into the one or more three-dimensional portions of the foodstuff.

2. The system of claim 1 , wherein the three-dimensional map of the foodstuff includes indentations, contours and discontinuities of the foodstuff.

3. The system of claim 1 , wherein the three-dimensional map of the foodstuff includes three dimensions corresponding to thickness, width and length of the foodstuff.

4. The system of claim 1 , wherein the step of comparing the at least one desired three-dimensional shape with the generated three-dimensional map of the foodstuff includes adjusting the at least one desired three-dimensional shape relative to the three-dimensional map of the foodstuff.

5. The system of claim 4 , wherein said adjusting the at least one desired three-dimensional shape is done so as to achieve at least one desired weight for the one or more portioned foodstuffs to be produced.

6. The system of claim 5 , wherein said adjusting the at least one desired three-dimensional shape comprises varying the at least one desired three-dimensional shape along one dimension.

7. The system of claim 5 , wherein said adjusting the at least one desired three-dimensional shape entails varying the at least one desired three-dimensional shape along two dimensions that are generally orthogonal to each other.

8. The system of claim 4 , wherein said adjusting the at least one desired three-dimensional shape is done so that the at least one desired three-dimensional shape, as adjusted, would avoid defects in the foodstuff.

9. The system of claim 8 , wherein said adjusting the at least one desired three-dimensional shape entails varying the at least one desired three-dimensional shape along one dimension.

10. The system of claim 8 , wherein said adjusting the at least one desired three-dimensional shape entails rotating the at least one desired three-dimensional shape relative to the three-dimensional map of the foodstuff.

11. A system for cutting foodstuffs comprising:
a computer central processing unit coupled to a cutter and to a scanner, and a storage device coupled with the computer central processing unit, the storage device containing computer-executable instructions which are loaded onto the computer central processing unit and cause the computer central processing unit to perform specific steps with respect to a work product in the form of a foodstuff to be portioned into one or more desired three-dimensional shapes, said steps comprising:
sending instructional signals to the scanner to cause the scanner to scan the foodstuff to be portioned;
receiving scan information from the scanner of the foodstuff to be portioned;
building a three-dimensional map of the foodstuff based on the received scan information from the scan of the foodstuff;
comparing at least one desired three-dimensional shape, which is stored in the storage device, with the three-dimensional map of the foodstuff;
determining one or more cutting paths to be used in portioning the foodstuff into a three-dimensional shape so as to produce one or more of the three-dimensional portions of the foodstuffs, each corresponding to the at least one desired three-dimensional shape; and
sending control signals to the cutter to control the operation of the cutter to cut the foodstuff into one or more desired three dimensional shapes in accordance with the determined cutting paths.

12. The system of claim 11 , wherein the step of comparing the at least one desired three-dimensional shape with the three-dimensional map of the foodstuff includes adjusting the at least one desired three-dimensional shape relative to the three-dimensional map of the foodstuff.

13. The system of claim 12 , wherein said adjusting the at least one desired three-dimensional shape of the foodstuff is done so as to achieve at least one desired weight for the one or more portioned foodstuffs to be produced.

14. The system of claim 13 , wherein said adjusting the at least one desired three-dimensional shape of the foodstuff entails varying the at least one desired three-dimensional shape along one dimension.

15. The system of claim 13 , wherein said adjusting the at least one desired three-dimensional shape of the foodstuff entails varying the at least one desired three-dimensional shape of the foodstuff along two dimensions that are generally orthogonal to each other.

16. The system of claim 12 , wherein said adjusting the at least one desired three-dimensional shape of the foodstuff is done so that the at least one desired three-dimensional shape of the foodstuff, as adjusted, would avoid defects in the foodstuff.

17. The system of claim 16 , wherein said adjusting the at least one desired three-dimensional shape of the foodstuff entails varying the at least one desired three-dimensional shape of the foodstuff along one dimension.

18. The system of claim 16 , wherein said adjusting the at least one desired three-dimensional shape of the foodstuff entails rotating the at least one desired three-dimensional shape of the foodstuff relative to the three-dimensional map of the foodstuff.

19. A system for cutting foodstuffs comprising:
a computer including a computer memory device,
a cutter coupled to the computer, and
a scanner coupled to the computer,
the computer memory device containing computer-executable instructions that cause the computer to perform specific steps with respect to a foodstuff to be portioned into one or more desired three dimensional shapes, said steps comprising:
sending instructional signals to the scanner to cause the scanner to scan the foodstuff to be portioned;
receiving scan information from the scanner of the foodstuff to be portioned;
building a three dimensional map of the foodstuff based on the received scan information from the scan of the foodstuff;
comparing at least one desired three dimensional shape, which is stored in the computer memory device, with the three dimensional map of the foodstuff;
determining one or more cutting paths to be used in portioning the foodstuff into a three dimensional shape so as to produce one or more of the three-dimensional portions of the foodstuffs, each corresponding to the at least one desired three dimensional shape; and
sending control signals to the cutter to control the operation of the cutter to cut the foodstuff into one or more desired three dimensional shapes in accordance with the determined cutting paths.
