WEINIG EScan

The WEINIG EScan is an automated inline inspection and sorting system that measures the structural properties of individual wooden boards to assign certified strength classes according to EN-14081 standards. Using laser interferometry combined with vibration analysis, the system quantifies the dynamic E-module (MOEdyn,long) and density of each board as it passes on a cross conveyor, enabling real-time classification without material destruction or processing delays. The system's core technical advantage lies in its dual-measurement approach: laser interferometry captures precise acoustic properties while vibration analysis validates structural integrity across the board length. By calculating both MOEdyn,long and density (ρ), the EScan can predict bending strength with sufficient accuracy to certify products for strength-graded applications. This non-destructive method eliminates the need for destructive sampling while maintaining traceability for each individual component. The EScan is designed for industrial woodworking facilities producing engineered wood products where strength certification is contractually mandated. Target applications include glulam manufacturers, DUO/TRIO panel producers, and structural timber operations processing volumes of 50+ cubic meters per shift. The system integrates into existing production lines without requiring major conveyor modifications, making it suitable for retrofit installations in medium to large operations. Compared to alternative sorting technologies, the EScan provides certified strength classification rather than simple grading, enabling premium positioning in markets where EN-14081 compliance commands price premiums. The non-contact measurement approach eliminates wear on sensing equipment and reduces false rejections caused by surface defects unrelated to structural performance.
