Bottle Thread Inspection

This vision application inspects coloured plastic and glass bottles to check that the thread dimensions are acceptable.

The bottles are backlit to provide a silhouette of the thread form. Using a single Cognex In-Sight Vision Sensor, the camera uses edge and measurement tools to check the thread and inspect for thread damage.

Features of the system:

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