Abstract
Method of optical inspection of closures on containers in which the outer edge of a closure is illuminated obliquely from above over the full circumference, and a photograph of the top side of the closure is made perpendicularly from above, and this photograph is used to detect the outer edge of the mouth, which appears brighter, and to check on the position of the cover logo relative to this edge of the mouth either directly or indirectly, and a signal is generated in the event an unacceptable eccentricity is found.
Claims3
A method of optical inspection of closures on containers, comprising:
- illuminating the outer edge of a closure obliquely from above, making a photograph of the top side of the closure perpendicularly from above, using this photograph to determine the outer edge of the closure, which appears brighter, checking, either directly or indirectly, on the position of a cover logo relative to this edge, and generating a signal in the event an unacceptable eccentricity is found.
