EHP European-Hardwood Production operates a hardwood lumber mill employing band saw technology that processes some 50,000 solid cubic meters of wood annually in Frauental, Austria. The requirements included flexible adaptability, robust durability within its operational environment, rapid integration, ease of operation, and low investment and operating costs.
The solution entails integrating a laser measurement system (LMS400) into an existing log band saw. The measurement surveys the contours, dimensions, cut type, and surface characteristics of each tree trunk. This data is processed to create a 3D model, which a saw pattern optimization program uses to determine sawn timber recovery on the basis of the final product weight, and displays cross-sections and suggestions for cutting the wood. Because the entire tree truck is surveyed and measured, the shape and structure of the tree trunk do not affect automated processing. A variety of log records and lists, such as volume and performance records, can be generated by specific date, if required.
By integrating a laser measurement systems from SICK, Hisoft was able to provide EHP with an easily integrated, reliable, rapid and cost-effective solution to optimize sawn timber recovery. Because of its flexibility and its easily adjustable measurement parameters, Hisoft was able to optimally parameterize the laser measurement system to the task. With an overall concept, which combines laser measurement and computerized assessment, small and mid-sized firms are provided with an innovative, easily integrated, and cost-effective solution to increase profitability, both in new construction and in modernization.
