System Uses Telecentric Lens to Inspect Bottle Necks

Mettler-Toledo CI-Vision introduced an advanced inspection system that accurately inspects bottle necks regardless of the position of the bottle on the conveyor by utilizing a Telecentric lens.

Through the use of telecentric lenses, the Empty Bottle Inspection system more accurately then ever verifies that neck threads are completely formed and not notched, inspects the sealing surface of the neck for planarity and detects molding flash.  An overhead camera inspects for choked neck opening and for ovality of the neck opening.

The system can also inspect the bottle sidewalls and bottom for embedded particulate contamination, blisters and bubbles in material, and window flaws such as swirls in coloring and imperfections in surface finish. The advanced system utilizes multiple cameras and sophisticated CIVCore proprietary software to complete all of these inspection operations simultaneously, speeding bottles through the inspection process. The system also changes over quickly to inspect new products. The system includes the vision processor, the neck inspection cameras with telecentric lenses as well as overhead and body inspection cameras, CIVCore Vision Engine software and all necessary cables as well as camera mounts, light mounts specific to the application and a touch screen monitor.
