Bottle Nozzle and Cap Inspection

This dual camera vision system inspects bottles post-filling, to ensure the nozzle and cap are fitted correctly.

One Cognex In-Sight Vision Sensor is installed at the post-nozzle fitting station, and the second camera shortly after the capping process.  A red LED backlight fitted behind the conveyor to silhouette the bottle, removes any confusing reflections from the front of the bottles.

Problems that can be detected by the system:

  • Missing nozzle
  • Cross-threaded nozzle
  • Loose nozzle
  • Missing cap
  • Cross-threaded cap
  • Loose cap

Features of the system:

  • High performance In-Sight Vision Sensors
  • Robust camera housings to IP67
  • Washdown LED backlights
  • Robust inspection tools to identify a number of failure modes
  • Virtually maintenance-free system
  • Simple HMI showing both bottles to allow reject images to be displayed
  • Simple interface to line PLC allowing rejected bottles to be tracked through to reject stations
