Defect detection on PET bottles

Defect detection on PET bottles

The vision system inspects the surfaces and rim of PET bottles.

The Trend Edge Stain tool generates a reference model that follows the contour of the bottle neck. Flaws along the elliptical edge deviate from the reference model and are detected as defects. Fine Colour processing detects any variances in colour from the bottle's surface as a stain with minimal programming.


Previously, extracting flaws that vary greatly in colour was extremely difficult and the bottle's elliptical appearance made inspecting the rim of the target for defects impossible. The XG Series' Trend Edge Stain tool and Fine Colour Processing easily accomplishes this task providing users with a complete solution.
