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
