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
