Cognex sensor checking bottle quality

A  customer application success story from Cognex.

When Meridian Beverage Co.’s new high-tech bottling line needed fill-and-cap verification, services provider Hamilton/ITS specified a reliable inspection sensor from Cognex that uses patterns to detect and inspect bottles and caps at speeds of 375 per minute. The challenge presented to Hamilton/ITS of Vidalia, Georgia was to provide a reliable “Fill & Cap” verification system for a new bottling line on behalf of Meridian Beverage Company of Atlanta.“The challenge is to kick out bottles that haven’t filled properly or have had the caps put on wrong.” Said Ray Hamilton, president of Hamilton/ITS.  “The new line runs almost non-stop at 375 bottles a minute so down time on our system wasn’t an option” he continued.

Cognex In-Sight 2000 sensors are the simple and affordable solution for verifying the presence of product and packaging features. Essentially a versatile “multi-sensor”, a single sensor detects features that would require multiple photoelectric sensors, or may not be within the capability of photo-electrics.

The sensor sensed 7 different features and sampled 5-7 snapshots of each bottle. The numerous snapshots reduced false negative responses. It self triggered, eliminating the need for an external sensor circuitry. Eliminating external sensors reduces costs of acquisition, design, installation and maintenance. After final in-place tuning, the system tested 100% f0r cap placement and proper fill level. Bottles were fed shoulder to shoulder and at 375 bottles a minute.
