Quality improvement for the massive wood sector is possible: at the Fill World Premiere Event, the first fully automated repair unit for massive wood boards was presented by Fill and Baumer Inspection.

The system, which inspects and repairs the massive wood boards over the entire surface, has been jointly developed by Fill and Baumer Inspection. Baumer’s inspection system detects defects like knot holes, resin pockets or disruptions and reports them to the repair unit. In this inspection process, the inspection unit’s tolerance of contamination is of particular importance: the quality inspection ignores oil stains and footprints. A benefit of the repair unit is the exact description, definition and recording of all repair components used as well as the number of repair processes carried out. With this information, a producer of solid wood boards is able to evaluate the data statistically.

The target group comprises producers of massive wood boards as well as of parquet. Due to the modular configuration of the repair unit, customers’ requirements or applications can be individually realized.
The repair unit carries out double-sided mending of boards of a maximum format of 5 x 2.1 m (l x w) and a thickness of 10 – 60 mm. The inspection unit scans the uncut, unformatted boards on the upper and lower side at a speed of 45 m/min. The defects are forwarded directly via CAM-interface. Every repair station consists of three placing units for natural knot dowels as well as a placing unit for resin pockets. Every placing unit comprises functions for milling, gluing and repairing. The stations synchronously mend the corresponding defects of the massive wood board according to the information of the inspection unit.

The first system will be employed in the next months at an Austrian producer of wood boards.
