Log processing device with deicing and thermal imaging
The patent US12023825B2 describes a comprehensive device and method for processing logs, integrating several key components to enhance efficiency and control during the deicing and debarking processes. The device includes a deicing apparatus, a debarking apparatus positioned downstream, and a thermal camera that captures thermal images of logs after debarking. A processing device analyzes these thermal images to determine the surface temperature of the logs and generates control signals for the deicing apparatus based on this temperature. Additional features include temperature sensors for measuring the temperature of the deicing medium and bark, which further inform the control signals, allowing for adjustments in both deicing and debarking intensities.
The method outlined in the patent involves a systematic approach to log processing, starting with deicing, followed by debarking, and concluding with thermal imaging and analysis. The processing device not only assesses the log surface temperature but also considers the temperatures of the used deicing medium and bark to optimize operations. The method allows for the processing of multiple logs simultaneously or individually, and it includes provisions for cutting logs into chips after debarking. The integration of thermal imaging with visual spectrum data enhances the ability to distinguish log surfaces from their backgrounds, ensuring precise control throughout the processing stages. Overall, this patent presents a novel solution aimed at improving the efficiency and effectiveness of log processing operations.
