INNOVATIVENEWS O L U T I O N STECHNOLOGY SESSION: BRINGING GRADE TO THE SAWMILLBEST-IN-CLASS BioLuma sensor technologyThis technology session was presented by ScottNorton, Operations Manager for Optimization andControls. Scott’s presentation covered sawmill gradeoptimization, and he outlined the technologies andprocesses that USNR employs to deliver gradingsolutions for the green mill.USNR’s talented group of engineers and technicianshave a wealth of knowledge and experience insawmill and planer mill scanning and optimization.Combined with an in-depth understanding of theissues that market demands place on the process,this is where inspiration meets opportunity.Proven methodsUSNR’s philosophy is to develop custom solutions toproblems, not custom platforms. We believe in usingmainstream platforms, and we leverage those acrossour entire suite of products. USNR’s engineeringteams all utilize the same technologies that have beenBioLuma sensors and capabilitiesBright, white and coolLED lighting2900L 2900LV 2900LVG 2900LVG+0.3” Laser profiling X X X XColor vision 0.02” 0.02” 0.01”GrainMap X XApplication Sawmill profiling SawmillclassificationSawmill grading Final grade(planer mill)Brilliant illumination: LED lighting ismounted independently from the sensors toachieve the optimum angle for illuminatingvisual characteristics, with a singleconnection for power and synchronization.Highest density laser profile scanningGrainMap grain anglemeasurementsAccurate laser profile measurements are an essential foundationupon which to build quality optimization decisions. With theindustry’s highest laser profile density, BioLuma sensors deliver.High density color visionHigh density color vision is required to accurately detect fine defects such as small knots, smallcracks, shake, rot, pith, etc.GrainMap is an additional channel ofinformation that ensures the system locatesand measures the knots correctly. GrainMapallows us to map and measure the actualgrain structure of wood. It utilizes theprinciple of dot vector laser tracheidimaging. Laser light becomes elongatedas it “wicks” along the grain structure,however when it is projected on a knot itretains its round shape.16Millwide INSIDER | ISSUE 6 - 2012
