Abstract

Disclosed are product processing systems and methods for monitoring, inspecting and controlling baking, cooking and routing processes, and the like. Products are placed on and moved by a conveyor. Images of the moving products are generated, such as by an image acquisition system. The images are processed by a symbol generation system. Symbols are then displayed on selected moving products based upon predetermined criteria. The systems and methods may be used to process oven-cooked or oven-baked products to identify (via the projected symbols) products that are defective or otherwise unacceptable. The product processing systems may be used to process packages or items having barcodes or other identifying labels to display routing or other identifying information on the moving products.

Claims

1. Apparatus, comprising:

a conveyor for moving products;

an image acquisition system for generating images of products moved by the conveyor; and

a symbol generation system coupled to the image acquisition system for processing the generated images and for displaying symbols on selected products moved by the conveyor based upon predetermined criteria.

2. The apparatus recited in claim 1 further comprising a product processor for processing product that is transferred onto the conveyor.

3. The apparatus recited in claim 2 wherein the product processor comprises an oven and wherein the conveyor is operative to move products cooked or baked in the oven.

4. The apparatus recited in claim 1 which comprises software algorithms that:

generates images of products moved past the image acquisition apparatus;

identifies selected products in the generated images based upon predetermined criteria; and

displays symbols on the identified products moved by the conveyor.

5. The apparatus recited in claim 4 wherein the image acquisition system comprises a visible imaging system.

6. The apparatus recited in claim 1 wherein the image acquisition system thermal imaging system.

7. The apparatus recited in claim 1 wherein the symbol generation system comprises a laser projection system.

8. The apparatus recited in claim 1 wherein the symbol generation system comprises a liquid crystal display (LCD) projection system.

9. The apparatus recited in claim 1 wherein the wherein the symbol generation system comprises a pan-and-tilt laser pointing system.

10. The apparatus recited in claim 1 wherein the symbol generation system comprises dual axis mirror beamsteering system.

11. The apparatus recited in claim 1 further comprising a bar code reader for identifying product on the conveyor.

12. Apparatus, comprising:

an oven;

a conveyor for moving products cooked or baked in the oven;

an image acquisition system for generating images of products moved by the conveyor; and

a symbol generation system coupled to the image acquisition system for processing the generated images and for displaying symbols on selected products moved by the conveyor based upon predetermined criteria related to temperatures of the products.

13. The apparatus recited in claim 12 which comprises software algorithms that:

generates images of products moved past the image acquisition apparatus;

identifies selected products in the generated images based upon temperatures of the products; and

displays symbols on the identified products moved by the conveyor.

14. Apparatus, comprising:

a conveyor for moving products having identifiers thereon;

an image acquisition system for generating images of products moved by the conveyor; and

a symbol generation system coupled to the image acquisition system for processing the generated images and information corresponding to the identifiers, and for displaying symbols on selected products moved by the conveyor based upon the information contained in the identifiers.

15. The apparatus recited in claim 14 further comprising a bar code reader for reading the identifiers to identify the products on the conveyor to generate the information corresponding to the identifiers.

16. A method comprising:

conveying products past image acquisition apparatus;

generating images of products moved past the image acquisition apparatus;

identifying selected products in the generated images based upon predetermined criteria; and

displaying symbols on the identified products as they are conveyed.

17. The method recited in claim 16 further comprising.

determining locations of conveyed products in the images;

tracking the locations of the conveyed products as they are conveyed;

displaying symbols on the identified products as they are conveyed.

18. The method recited in claim 16 further comprising removing the identified products from products that are conveyed past the inspection apparatus.

19. The method recited in claim 16 wherein the predetermined manner of processing the products is selected from a group including cooking, baking, and routing.

20. The method recited in claim 16 further comprising:

tracking the conveyed products using barcodes.
