Abstract

First scanned images of the first container are received from a scanning device that show the contents of the interior of the first container before the first container is cut and opened. Second scanned images that are of the contents of the first container after the first container is cut and opened are also received. The images are analyzed and, based upon the analysis, selective modifications to the operating parameters of the container opening machine are determined and made.

First claim

What is claimed is:

1. A system for opening a container, the system comprising:
a scanning surface;
a plurality of containers that arrive and are sequentially placed on the scanning surface, the plurality of containers including a first container and a second container;
a scanning device;
a database;
a container opening machine including at least one cutting tool, the at least one cutting tool being one or more of a saw or a laser, wherein the at least one cutting tool is applied to each of the plurality of containers arriving on the scanning surface, and wherein the container opening machine is operated and a container is cut and opened by the container opening machine according to one or more operating parameters; and
a control circuit coupled to the database, the scanning device, and the container opening machine, wherein the control circuit is configured to:
receive first scanned images of the first container from the scanning device, the first scanned images being of one or more contents-inside of the first container before the first container is cut and opened, and second scanned images being of the one or more contents of the first container after the first container is cut and opened;
comparing the first scanned images and the second scanned images;
based upon the comparing, determine an existence of damage to the one or more contents of the first container;
based upon an analysis of the damage, selectively determine a modification to the one or more operating parameters of the container opening machine; and
apply the modified one or more operating parameters to the container opening machine, wherein the container opening machine opens the second container using the modified one or more operating parameters.

2. The system of claim 1 , wherein the analysis of the damage compares shapes of the one or more contents in the first container before and after the first container is opened.

3. The system of claim 1 , wherein after the analysis of the damage is conducted, a determination is made that there are no changes to the one or more operating parameters of the container opening machine.

4. The system of claim 1 , wherein the one or more operating parameters include one or more of: a cutting depth of the at least one cutting tool, a location of a cut, and a shape of a cut.

5. The system of claim 1 , wherein the modification to the one or more operating parameters comprise changes to one or more parameters that change a type of cutting tool used.

6. The system of claim 1 , wherein the analysis of the damage classifies the damage among a plurality of categories.

7. The system of claim 1 , wherein the analysis of the damage indicates that shapes of the one or more contents in the first container changed indicating that the at least one cutting tool has damaged items in the first container.

8. The system of claim 1 , wherein the database stores images of undamaged items which are used in the analysis of the damage.

9. The system of claim 1 , wherein the scanning surface is a conveyor belt.

10. A method for opening a container, the method comprising:
providing a scanning surface, and a plurality of containers that arrive and are sequentially placed on the scanning surface, the plurality of containers including a first container and a second container;
providing a scanning device;
providing a database;
providing a container opening machine that includes at least one cutting tool, the at least one cutting tool being one or more of a saw or a laser, wherein the at least one cutting tool is applied to each of the plurality of containers arriving on the scanning surface, and wherein the container opening machine is operated and a container is cut and opened by the container opening machine according to one or more operating parameters;
at a control circuit, receiving first scanned images of the first container from the scanning device, the first scanned images being of one or more contents inside of the first container before the first container is cut and opened, and second scanned images being of the one or more contents of the first container after the first container is cut and opened;
at the control circuit, comparing the first scanned images and the second scanned images;
at the control circuit, based upon the comparing, determining an existence of damage to the one or more contents of the first container;
at the control circuit, based upon an analysis of the damage, selectively determining a modification to the one or more operating parameters of the container opening machine; and
by the control circuit, applying the modified one or more operating parameters to the container opening machine, wherein the container opening machine opens the second container using the modified one or more operating parameters.

11. The method of claim 10 , wherein the analysis of the damage compares shapes of the one or more contents in the first container before and after the first container is opened.

12. The method of claim 10 , wherein after the analysis of the damage is conducted, a determination is made that there are no changes to the one or more operating parameters of the container opening machine.

13. The method of claim 10 , wherein the one or more operating parameters include one or more of: a cutting depth of the at least one cutting tool, a location of a cut, and a shape of a cut.

14. The method of claim 10 , wherein the modification to the one or more operating parameters comprise changes to one or more parameters that change a type of cutting tool used.

15. The method of claim 10 , wherein the analysis of the damage classifies the damage among a plurality of categories.

16. The method of claim 10 , wherein the analysis of the damage indicates that shapes of the one or more contents in the first container changed indicating that the at least one cutting tool has damaged items in the first container.

17. The method of claim 10 , wherein the database stores images of undamaged items which are used in the analysis of the damage.

18. The method of claim 10 , wherein the scanning surface is a conveyor belt.
