New developments. Among the most relevant novelties is RuScan lumber quality and geometrical parameters scanner with trimming optimization function. This system is designed for lumber sorting lines operating at speeds from 60 to 180 boards per minute.
Hardware and software complexe was developed by AVTOMATIKA-VEKTOR. Actually scanner is a line of sensors, located for every 10 or 30 cm that are connected to a special computer with specialized software and have the function of optimization for clean sawn face or for timber sales value. The typical system for sorting and trimming of raw timber includes 28 triangulation sensors, located from the length of 2.4 meters and every 30 cm. The sensors are mounted above and below the board. The system reliably detects the board geometric parameters and wane regardless of the spatial orientation of the board and wane position on the board. All sensors are strictly synchronized with each other; the geometric model of the board is built into the computer's memory quite easily. Based on these data, the software calculates the various geometrical misalignments from the model parameters and does the analysis for decision making. Information from the sensors is transmitted to a computer in digital form and this allows to obtain long term repeatability and accuracy of measurements, as well as ensures a high anti-interference ability of the data channel.
The scanner is mounted on a special measuring station of sorting line; the output signals from the computer control the operation of the trimmer. After scanning each board geometry and proceeding this information into the computer, the software processes the information, analyzes possible variants of board trimming and chooses the best one. Applications of such a complex allows to raise the profitability of the sawmill for 2-3% as compared to manual operation mode.
