New Dual Profiling Inspection System Uses Two Lasers to Ensure Cap Sealing
Silgan Equipment's new 2D-X2 Inspection System employs dual lasers to scan the surface of the cap on a packaged beverage or food product to determine proper cap sealing. The side-by-side laser beams scan the top surface of each cap to immediately detect cap tilt and overall cap height. When the lasers detect an uneven cap height, the cap is cocked; when they detect a non-standard package height, the cap is either low (not present) or is high (not completely seated). These results indicate a package that is not securely sealed.
The 2D-X2 system installs over an existing conveyor line, saving valuable floor space. The lasers are mounted in a protective housing rated NEMA 4X, resistant to washdowns and the harsh conditions of the processing environment. The sensor height is adjusted by a handwheel, and the beam-spread adjustment by a rotary knob, allowing for fast and accurate placement. As filled and capped containers pass, the lasers scan the surface of each cap to identify rejects for removal downstream.
