GapChek images the front and back of each corrugated box bundle to measure manufacturer's joint folded gaps. Two cameras mount over the conveyor after the counter-ejector on the Flexo-Folder-Gluer, fixed in height above the tallest bundle. During order setup, the cameras servo-position left or right to align with the gap in the bundle. One camera reads the rear face of the bundle for trailing edge gaps. The other reads the front face for leading edge gaps. Lights near each camera illuminate the bundles during imaging.
Gap measurements for every box display on the monitor. Boxes with gaps outside of tolerance are highlighted on the screen for removal. When paired with BundleChek, bundles containing defective gaps are automatically ejected from the line, and an operator can sort the defects out of the ejected bundle.
