Goldeneye 700: Scanner boosts performance and yield

For the new MiCROTEC scanner at Lignopan, it's always Monday morning - whether it's Friday afternoon or Wednesday night. Regardless of the time of day or the state of mind, the Goldeneye 702 assesses each lamella according to the same criteria every time, which significantly increases the raw material yield.

Specifically, Lignopan ordered a Goldeneye 702 lumber scanner including Warpscan and mechanization from System TM. The Warpscan 3D board shape scanner detects shape deviations in the sawn timber, such as twisting, curvature and cupping in cross transport. "In doing so, the system uses the triangulation method to measure the geometry of the sawn timber, even if it is moved during the measurement," explains MiCROTEC Sales Representative Axel Creuzberger.

Lignopan uses the Goldeneye 702 primarily for strength grading. For this purpose, the raw material is positioned automatically on the center and fed through the scanner in a longitudinal pass. In addition to the dimension, fiber deviation and color, an X-ray module determines the bulk density, from which the strength is subsequently calculated. Creuzberger puts the throughput speed at up to 300 m/min in this system, depending on the dimension. The mechanical strength grading system is also equipped with a specially approved software module that allows evaluation of the virtually separated board halves.

The scanner was installed over a weekend in December last year, and the company is now in the optimization phase for all products. Once this is complete, Lignopan expects a 1% increase in raw material yield due to the precise and always consistent quality assessment. This doesn't sound much at first, but it can save the company €400,000 to €500,000/year in the future.

A fact that makes the Goldeneye interesting for more and more KVH manufacturers, as Creuzberger reports: "Demand from this sector has grown significantly recently. More and more KVH producers are recognizing the technical and, above all, economic advantages of machine strength grading and are now following suit."
