The Surface Inspection System FIBERVIEW monitors the fibre quality inline on the basis of the number and size of shives, thus ensuring a continuous, consistent monitoring of the spread fibres in the MDF panelproduction. Fault reports and statistical data allow detailed conclusions of the upstream production process.
Benefits at a glance
- Reliable, objective and representative evaluation of fibre quality
- Control and optimisation of the refining process
- Quality assurance and reduced customer complaints
- Reduced energy consumption by the refiner
Design of the system
The measuring system is a solid, closed frame construction. The visual field of the camera is protected from dirt and dust by a tube. The entire camera and illumination unit automatically adjusts to changing working levels depending on the mat height. Changes in light intensity of the fibre mat due to different wood types, mixtures, changes in moisture or cooking conditions are automatically compensated.
The fibre mat is inspected by a camera system after the pre-press across a width of about 400 mm. Constant measuring conditions are created by automatic height adjustment of the camera and illumination unit including light regulation, independent of panel type and ambient conditions. The shives are automatically detected and classified by three image processing steps. This process is accomplished continuously – usually every 3 s – during the production so that representative information on the fibre quality is available in real time. With this technology, it is possible for the first time to evaluate the refining process objectively. The energy consumption of the refiner can be optimised depending on the required fibre quality. For example, the process can be directly influenced by changing the distance of the refiner discs, thus reducing energy needed to produce optimal sized shives.

The visualisation software of all GreCon measuring systems is based on Windows.
The core of the software package is the visualisation software. It records, stores and graphically represents all measured data. The simple menu structure, which is identical for all GreCon measuring systems, provides intuitive and user-friendly operation.
The database stores the measured values, thus allowing the operator to call up all events from history for analysis at any time.
Using special software, individual time-related reports, such as shift or monthly reports, can be generated from the database.
For the data transmission to higher-ranking process control systems, different network connections, such as OPC, are available.

GreCon measuring systems are generally equipped with the online support GreCon SATELLITE. On demand, this system provides safe and fast remote support. Each online support is logged and stored in the system’s history.
