Reliably detecting six-packs in PET film on conveyor systems is a real challenge for optical sensors. The new WTB27-3 Multipac photoelectric proximity sensor from SICK helps automation specialists in diverse industries to detect shiny and uneven objects such as foil-wrapped six-packs or shiny metal surfaces on conveyors.
Conventional photoelectric sensors used in this application were facing problems from incalculable reflections from the film, uneven surfaces and different container heights depending on bottle size.
The WTB27-3 Multipac overcomes the limitations of the previous sensors in detecting highly reflective and uneven surfaces by combining measures such as using two completely separate receiver systems to double the detection performance, generating extremely high light intensity with a high-power LED and controlling the complex evaluation using the application-specific software.
Key benefits of WTB27-3 Multipac photoelectric proximity sensors:
- Checks and controls transport of packaging units on single or multi-track conveyor systems very efficiently
- Reliably detects shiny or uneven objects on conveyors
- Sensor may be mounted up to 500mm above the conveyor system to detect diverse types and heights of packaging units with only one fixed sensor position
- Eliminates need for mechanical height adjustment, reducing effort and expense for users
