Goldeneye: The heart of the line

Holzwerke Pröbstl’s new production line for top-layer lamellas has been in operation for a few months now. In order to guarantee high quality and top performance at the same time, the company once again relied on a MiCROTEC scanner.

Single, three- and five-layer panels in spruce, fir and larch wood, manufactured individually according to customer requirements – that is the specialty of Holzwerke Pröbstl, Fuchstal-Asch/DE. In order to be able to respond quickly to market requirements on the one hand and to further automate production on the other, the company invested in a new top layer production line. For the scanner, the three managing directors, Helmut Pröbstl and his daughters Irmi Merkle-Pröbstl and Elisabeth Engel-Pröbstl, once again relied on technology from MiCROTEC. Since the company chose the same system again, employees did not have to undergo any extensive training.

Fully equipped scanner

Specifically, MiCROTEC supplied a Goldeneye scanner and the ID Scan. In the top layer production, spruce, fir and larch lumber is first cut into lamellas. Next, the lamellas pass through the Goldeneye longitudinally. The scanner is designed for lamellas with lengths of 4.1 to 5 m, widths of 97 to 170 mm and thicknesses of 4.5 to 13 mm. The scanner can work at feed speeds of up to 400 m/min. “We delivered a full system with two-sided detection. The Goldeneye is equipped with dimension measurement, scattering laser, color module and sensors for detecting diagonal cracks,” Peter Hagnberger, managing director of MiCROTEC Rosenheim, specifies. Each slat is attributed a type of quality according to the classification.

 

In addition, the Goldeneye in use at Holzwerke Pröbstl is equipped with artificial intelligence. “The Goldeneye scanner perfectly recognizes every characteristic of the lamellas, especially when distinguishing between brown rot, compression wood or a tangential grain structure,” Engel-Pröbstl explains, who is responsible for technology in the family business, and adds: “With the help of AI, we were able to increase quality even further.”

 

“As a rule, the majority actually goes into top layer production. However, around 8% of what we process in this plant are not of a sufficient quality. We use those lamellas to produce middle layers exclusively for our own further processing,” Engel-Pröbstl explains. In concrete terms, this means that whenever the Goldeneye attributes the quality “middle layer” to a lamella, the mechanization collects it separately and then transports it to a cross-cut saw where the lamellas are separated.

To recognize the respective lamellas, MiCROTEC installed its ID Scan. “This board tracker is used to recognize each piece, thereby enabling us to transfer the data from the Goldeneye to the downstream cross-cut saw,” Hagnberger explains. The ID scan “measures” the first 30 cm of the lamellas, matches them with the data and can then transfer them accordingly. “Our middle layers are top-notch. Since we use the data from the Goldeneye for the cross-cutting, we get a nice, even surface,” Engel-Pröbstl emphasizes.
