"The professional cooperation between our partners System TM, Oki Kikai Co. Ltd. and the customer Chugoku Lumber Co. has been very good during all the phases of the project. This has been a very good experience and we are very proud to have installed the first Viscan for strength grading in Japan."
Microtec and System TM completed the project successfully for the customer Chugoku Lumber in Hyuga, Miyazaki Prefecture, Japan. System TM delivered a high-speed moulder line for finger joint and glued laminated boards. The workpieces are high-speed single-piece fed to a stud carrier that consists of a moisture meter, a Curvescan from Microtec, an automatic out sorting of workpieces for finger joint, a high-speed board turner and a multi-head cross cut saw, that cuts the workpieces in very exact lengths.
The cut workpieces are transported through a Viscan from Microtec before being distributed between two moulders that are running different dimensions. The main focus of System TM and Microtec solutions is to optimize the raw material, wood, in order to have the maximum yield. So Microtec implemented the first Viscan in Japan. This measuring unit determines the resonant frequency by a high performance laser vibrometer. According to this selection Microtec provides also an output control for grading classes and also supports the customer in finding the thresholds.
The other solution is a Curvescan shape scanner that works in transversal feeding and thanks to a sophisticated laser triangulation process, it measures accurately the geometry of the workpieces. Curvescan works also at high-speed and generates constant and very reliable results. It determines twist, bow and spring according to the customer’s threshold values.
The board shape scanner measures the geometry of lumber at high-speed.
Integrated in the planer line the Viscan measures the strength of the boards.
