High-speed moulder line to Japan


High-speed moulder line to Japanese Chugoku Lumber Co.
Through great co-operation with our Japanese dealer Oki Kikai Co. Ltd., System TM managed to win the order of a high-speed moulder line to Chugoku Lumber Co. in Japan. System TM designed the system solution and implemented Microtec scanning equipment in the line.

The high-speed moulder line from System TM
The solution from System TM is a high-speed moulder line for finger joint and glued laminated boards.
The line consist of an automatic infeed system, a heavy duty Opti-Feed 6000. The infeed system is with continuous feed, ensuring that a pack is always ready on the conveyor belt to be fed to the line. The workpieces are high-speed single-piece fed to a stud carrier that consist 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 model MK2, that cuts the workpieces in very exact lengths.

The workpieces that are sorted for finger joint are stacked continuously and the packs are either transported to storage or destacked and fed to a finger jointing line.
The cut workpieces are transported through a Viscan from Microtec before being distributed between two moulders that are running different dimensions. After each moulder, an operator quality sorts the moulded workpieces and they are sorted between two automated Opti-Stack 3000 stacking systems. The line consist of four Opti-Stack 3000 in total.
When the packs are full they are automatically transported on a roller conveyor to a press line where the workpieces are glued, or an option is to take the packs and transport them to storage.

Solutions from Microtec
The main focus of System TM and our wood scanning partner Microtec, is to optimize and truly utilize the raw wood and wood resources of our customers. This is done through System TM’s designed system solutions combined with high scanning technology from Microtec.
The high-speed moulder line to Chugoku Lumber Co. is no exception, and the following equipment from Microtec has been implemented in the solution:

  • For the first time in Japan, a Microtec Viscan strength grading solution has been installed. Viscan is a measuring unit for determining resonant frequency thanks to a high performance laser vibrometer. Through this, Microtec provides an output control for grading classes and also supports the customer in finding the thresholds.
  • The second solution from Microtec is a Curvescan C shape scanner that works in transversal feeding and, thanks to a sophisticated laser triangulation process, accurately measures the geometry of the workpieces. Curvescan works at high-speed and generates constant and very reliable results. It determines twists, bows and spring on each workpiece according to the customer’s threshold values.
