Introducing advanced Blow Detection methods

9.12.2011

Electronic Wood Systems in Hameln, Germany introduces new technological improvements of blow detection systems required for the panelboard industry. This advance allows mills to not only reduce costly blows that can cripple manufacturing operations, but also upgrade their panel production efficiency. The new technologies identify changes in panel properties resulting in increased production capacity and minimizing material and energy consumption (wood, resin, energy). The benefits of taking corrective actions of production parameters before blows occur has strong influence on the technical design improvements of online measuring systems. The measurement results are also displayed as a sound picture which helps the operator to decide what corrective action needs to be done. Additionally, complex technological improvements called “Reflection Receivers” are installed on the new CONTI-SOUND system to compensate for the influence of varying properties and conditions of the panel surface. This state-of-the-art technology is primarily used in continuous press lines. “The first system was successfully installed at Kronoply MDF, Germany and three more CONTI-SOUND systems are under construction for a particleboard production line in China and MDF lines in Brazil and South Korea”, reported by general managers Matthias Fuchs and Hauke Kleinschmidt. Two other versions called BLOW-SCAN and PLY-SCAN have been developed by the German company at same time for applications in Plywood, Particleboard and OSB plants. All three EWS systems detect and compensate automatically for dust contamination on the sonic sensors and the systems are continuously calibrated online.

“A new BLOW-SCAN version was recently installed at Egger particleboard line, Shuya in Russia. Six more CONTI-SOUND systems have been shipped to be installed in new Siempelkamp production lines in Brazil, Korea and China. Also, the plywood mills in various countries show high interest in the new PLY-SCAN version. The new systems generation has been highly accepted in the panel market after successful response from the first installations”, the companies’ management says. All three systems have similar design, but differ in technical features as scope of data analysis and visualisation the selection and use of them takes place depending on the type of panel and its field application.
