Abstract: Near InfraRed NIR technology, including NIR cameras and detectors, and one or more visual cameras are used to generate superimposed image data representing a visual/NIR composite image of wood product and correlating moisture levels with physical features of the surfaces of the wood product. By analyzing the visual/NIR composite image represented by superimposed image data, moisture pockets near an open physical feature that, absent the presence open physical feature would be a problem, can be identified and ignored. Based on the identified moisture levels at various locations in a given wood product, and the proximity of physical features to the identified moisture locations, one or more actions are taken with respect to wood product to ensure the wood product is put to the most efficient, effective, and valuable use.

Abstract: Near InfraRed NIR technology, including NIR cameras and detectors, is used to accurately identify surface irregularities on a veneer surface. A grade is then assigned to the veneer based, at least in part, on the detected irregularities. In one embodiment, the veneer is then provided to an improved veneer stacking system that produces more consistently graded veneer stacks and safer veneer stacks, is less expensive to operate, and is far safer than currently available methods and systems for full veneer sheet, veneer strip, and partial veneer sheet stacking.

Abstract: Near InfraRed NIR technology, including NIR cameras and detectors, is used to accurately determine the strength of the green veneer sheet or other wood product. Based on the determined strength for a given green veneer sheet or other wood product, one or more actions are taken with respect to green veneer sheet or other wood product to ensure the green veneer sheet or other wood product is put the most efficient, effective, and valuable use.

Abstract: A method and system for production of layered wood products employs local and independently operating robotic panel assembly cells including one or more veneer handling robots, one or more core handling robots, and one or more glue application robots to produce stacks of layered wood product panels locally near the pressing stations. Consequently, the stacks of layered wood product panels are independently built at, or near, the location of the pressing stations. This eliminates the need for traditional panel conveyors, traditional layered wood product panel assembly layup lines, and stack press delivery lines. This, in turn, eliminates thousands of moving parts and dozens of people from the layered wood product production process.

Abstract: A method and system for production of layered wood products employs local and independently operating robotic panel assembly cells including a vison system for inspecting and grading veneer sheets, one or more veneer handling robots, one or more core handling robots, and one or more glue application robots to produce stacks of layered wood product panels locally near the pressing stations. Consequently, the stacks of layered wood product panels are independently built at, or near, the location of the pressing stations using inspected and graded veneer sheets. This eliminates the need for traditional panel conveyors, traditional layered wood product panel assembly layup lines, and stack press delivery lines. This, in turn, eliminates thousands of moving parts and dozens of people from the layered wood product production process.

Abstract: Near InfraRed NIR technology, including NIR cameras and detectors, and machine learning methods and systems, including one or more Machine Learning (ML) based moisture level detection models, are used to accurately identify moisture content and the specific locations of the moisture on an entire surface of a veneer sheet or other wood product and provide moisture level prediction data for the veneer sheet or other wood product. Based on the moisture level prediction data for a given wood product, one or more actions are taken with respect to wood product to ensure the wood product is put to the most efficient, effective, and valuable use.

Abstract: A density detection system uses a magnetic force feedback actuator positioner to maintain a precise selected pressure between transducer wheels and the surface of a sheet of material as the sheet of material moves through a position between transducer wheel and lift wheel. Consequently, the antiquated mechanical/pneumatic springs/airbags of prior art ultrasonic density detection systems are replaced with a highly responsive magnetic force feedback actuator positioner capable of providing a precise and relatively constant force that can react to the introduction of a sheet of material, and/or variations in the surface of a sheet of material, extremely rapidly without the bounce/recovery oscillations associated with prior art ultrasonic density detection systems. Consequently, precise density measurements of an entire sheet of material can be obtained with unprecedented accuracy.

Abstract: A method and system for a veneer grading and stacking uses one or more vision systems to generate images of the individual full or partial sheets of veneer and accurately determine the dimensions of each individual full or partial sheet of veneer. The one or more vision systems are also used to analyze the surface of each individual full or partial sheet of veneer quickly and automatically and assign a grade to each individual full or partial sheet of veneer. One or more veneer selection and stacking robots are then used to move each individual full or partial sheet of veneer from a veneer analysis and selection conveyor system to an appropriate veneer stack based on the grade assigned to the individual full or partial sheet by the one or more vision systems.
