Infrared detection of composite article components
DC CAFCFirst Claim
1. A process of inspecting a composite article having first and second panels in at least partially opposed, overlapping engagement with each other, the first panel having an underlying edge overlapped by at least a portion of the second panel which is substantially opaque to visible and/or ultraviolet light, said process to determine whether the panels of the article are present and/or properly positioned, said process comprising:
- irradiating the overlapping engagement of the panels with radiation;
producing an image from radiation received from the irradiated panels;
identifying in the image a position of the underlying edge; and
comparing the identified position of the underlying edge with a predetermined data to thereby determine whether the underlaying edge is present and/or properly positioned in the composite article.

Abstract
A system and process for inspecting an underlying edge of a composite article, such as a disposable absorbent article. The article has first and second panels in at least partially opposed, overlapping engagement with each other. The process and system determine whether the panels of the article are present and/or properly positioned. Also disclosed is a process and system for detecting whether one or more components are present and/or properly positioned in the composite article by use of infrared radiation. Also disclosed is a process and system for defining a window in an image of the article, scanning the defined window to determine a position of the edge and redefining the window in the event that the edge is not located within the defined window during scanning of the defined window.

9. A system for inspecting a composite article having first and second panels in at least partially opposed, overlapping engagement with each other, the first panel having an underlying edge overlapped by at least a portion of the second panel which is substantially opaque to visible and/or ultraviolet light, said system for determining whether the panels of the article are present and/or properly positioned, said system comprising:
-
a radiation source for irradiating the overlapping engagement of the panels with radiation;
a detector for producing an image from radiation received from the irradiated panels; and
an image analyzer operatively connected to the detector for identifying in the image a presence and/or position of the underlying edge and for comparing the identified presence and/or position of the underlying edge with a predetermined data to thereby determine whether the underlying edge is present and/or properly positioned in the composite article. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A process of detecting one or more components in a composite article, the process comprising:
-
irradiating the composite article with infrared radiation;
producing an image from infrared radiation received from the irradiated composite article;
identifying a position in the produced image corresponding to an underlying edge of a first component in the composite article, said underlying edge overlapped by at least a portion of a second component which is substantially opaque to visible and/or ultraviolet light; and
comparing the identified position with predetermined position data to thereby determine whether the first component is present and/or properly positioned in the composite article. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A system for detecting one or more components in a composite article, the process comprising:
-
an infrared radiation source for irradiating the composite article with infrared radiation;
an infrared detector for producing an image from infrared radiation received from the irradiated composite article; and
an image analyzer operatively connected to the infrared detector for identifying a position in the produced image corresponding to an underlying edge of a first component in the composite article, said underlying edge overlapped by at least a portion of a second component which is substantially opaque to visible and/or ultraviolet light, said image analyzer further for comparing the identified position with predetermined position data to thereby determine whether the first component is present and/or properly positioned in the composite article. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A process of inspecting a composite article having first and second panels in at least partially opposed, overlapping engagement with each ether and having an edge, said process to determine whether the panels of the article are properly positioned, said process comprising:
-
irradiating the overlapping engagement of the panels with radiation;
producing an image from radiation received from the irradiated panels;
defining a window in the image;
scanning the defined window to determine a position of the edge;
redefining the window in the event that the edge is not located within the defined window during the scanning of the defined window; and
comparing the determined position of the edge with a predetermined data to thereby determine whether the edge is properly positioned in the composite article. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)

39. A system for inspecting a composite article having first and second panels in at least partially opposed, overlapping engagement with each other and having an edge, said system for determining whether the panels of the article are properly positioned, said system comprising,
a radiation source for irradiating the overlapping engagement of the panels with radiation; -
a detector for producing an image from radiation received from the irradiated panels; and
an image analyzer operatively connected to the detector for defining a window in the image, for scanning the defined window to determine a position of the edge, for redefining the window in the event that the edge is not located within the defined window during the scanning of the defined window, arid for comparing the determined position of the edge with a predetermined data to thereby determine whether the edge is properly positioned in the composite article. - View Dependent Claims (40, 41, 42, 43, 44, 45)
