Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

WHAT IS CLAIMED IS:

1. An inspection system (100), comprising:

a background (102) positioned adjacent an inspection zone (104); and

an image capturing device (106) configured to receive background electromagnetic radiation (EMR) from the background and from the inspection zone, the inspection zone being configured and arranged to receive material for transport into the inspection zone; wherein the background has a background property defined by a background emission, a background absorbance, and a background reflectance, the background property being matched in EMR to a material EMR of material to be transported into the inspection zone, the material having a material property defined by a material emission, a material absorbance, and a material reflectance; and

wherein the image capturing device is configured to detect a foreign object within material when transported into the inspection zone by deducting the background EMR from the material EMR.

2. The inspection system recited in claim 1, in combination with at least one of: the material positioned in the inspection zone; or the foreign object within the material positioned in the inspection zone.

3. The inspection system recited in any of the preceding claims, wherein:

the material is meat.

4. The inspection system recited in any of the preceding claims, comprising: a computer device (108) in operative communication with the image capturing device, the computer device having a display (110) for displaying an image or graphical

representation of the material property and the background property.

5. The inspection system recited in any of the preceding claims, wherein:

the background property is selected as a function of a material which includes a first material and a foreign object material, wherein the first material has a first material property and the foreign object material has a second material property;

the first material property equals the background property; and

the second material property does not equal the background property.

6. The inspection system recited in any of the preceding claims, comprising: an illumination source (200) configured to generate and direct EMR into the inspection zone so that the EMR will interact with the background and will interact with the material when the material travels into the inspection zone.

7. The inspection system recited in any of the preceding claims, comprising: an illumination source configured to generate and direct EMR into the inspection zone so that the EMR will interact with the background and will interact with the material when the material travels into the inspection zone;

wherein:

the illumination source is configured to generate EMR having a wavelength in the visible spectrum;

the image capturing device is an optical camera;

the material includes a first material and a foreign object material;

the first material has a first material property and the foreign material has a second material property; and

the first material property causes the EMR interacted therewith to be within the red color spectrum and the background property causes the EMR interacted therewith to be within the red color spectrum.

8. The inspection system recited in any of the preceding claims, comprising: an illumination source (200) configured to generate EMR;

the inspection zone is segmented by a longitudinal plane into a first inspection zone side and a second inspection zone side;

the background includes a first background located in the first inspection zone side and a second background located in the second inspection zone side;

the material will travel into the inspection zone between the first background and the second background; and

the illumination source is configured to direct the EMR into the inspection zone so that the EMR will interact with the first background, the second background, and the material when the material travels into the inspection zone.

9. The inspection system recited in any of the preceding claims, wherein:

the image capturing device (106) includes a first image capturing device and a second image capturing device;

the first image capturing device is configured to detect whether the material property differs from the background property of the first background; and

the second image capturing device is configured to detect whether the material property differs from the background property of the second background.

10. A material processing system (500), comprising:

a conveyor system having a conveyor belt (502) configured to carry material, the conveyor belt including an outfeed conveyor belt (502b) being positioned so that the material will fall through an inspection zone (104) and land on the outfeed conveyor belt; and

an inspection system (100) according to any of the preceding claims and having: a background (102) positioned adjacent the inspection zone; and an image capturing device (106) configured to receive electromagnetic radiation (EMR) from the background and from the inspection zone, the inspection zone being configured and arranged to receive material for transport into the inspection zone;

wherein:

the background has a background property defined by a background emission, a background absorbance, and a background reflectance, the background property being matched in EMR to a material EMR of a material to be transported into the inspection zone, the material having a material property defined by a material emission, a material absorbance, and a material reflectance;

the image capturing device is configured to detect a foreign object within material when transported into the inspection zone by deducting the background EMR from the material EMR.

11. The material processing recited in claim 10, comprising:

a computer device (108) in operative communication with the image capturing device, the computer device having a display for displaying an image or graphical representation of the background property and the material property;

wherein the computer device includes a control module to control the operation of the conveyor belt.

12. The material processing recited in claim 10 or 11, comprising:

a separator unit (600) configured to separate and remove the foreign object from the conveyor belt.

13. A method for inspection using the inspection system (100) of any of the preceding claims, the method comprising:

positioning a background (102) adjacent an inspection zone, the background having a background property defined by a background emission, a background absorbance, and a background reflectance;

directing material of a material flow into the inspection zone, the material having a material property defined by a material emission, a material absorbance, and a material reflectance; and

detecting whether the material property differs from the background property by at least deducting electromagnetic radiation (EMR) of the background from EMR of the material.

14. The method recited in claim 13, comprising:

directing EMR into the inspection zone so that the EMR will interact with the background and will interact with the material when the material travels into the inspection zone;

segmenting the inspection zone by a longitudinal plane into a first inspection zone side and a second inspection zone side; and

positioning a first background in the first inspection zone side and a second background in the second inspection zone side.

15. The method recited in claim 13 or 14, comprising at least one or more of: directing EMR into the inspection zone so that EMR will interact with the first background, the second background, and the material when the material travels into the inspection zone;

displaying an image or graphical representation of the material property and the background property; or

separating and removing material from the material flow when the material property differs from the background property.
