machine vision and intelligent control. The finished sawn timber is auto matically transferred to the transport vehicle without forklift trucks. Automation provides accurate data Information about the logs to be sawn is collected and stored through- out the production process. Data about the quality and dimensions of logs is collected during grading, but X-ray cameras, machine vision and robotics are also used on the sawline. This helps to ensure that the wood is used as efficiently as possible. The logs are X-rayed to measure quality deviations, knots and knot fre- quency. After measurement, the control system grades the logs into saw- ing batches and links them to the intended final products. “The flow of timber in the sawline is constantly monitored by special cameras that detect defective pieces. Then automated robotics pick up the piece without manual intervention,” Haapaniemi explains. Operators monitor the process from a central control room, while ana- lysing the data collected from each work stage. This ensures efficient con- tinuous production and high-quality end products.
