| 摘要 |
The present invention relates to an arrangement and a method for monitoring progress of timber rotation before sawing machine in a sawmill. This aim is reached by providing a separate 3D-rotation scanner which identifies the previously 3D-scanned and measured log and which measures the rotation progress in the log turner in real time. Accordingly to the method, the already scanned and measured timber (log) is scanned again with additional 3D-rotation scanner and the newly scanned position of the timber is compared with the parameters of the previously scanned data and accordingly the process of the timber (log) rotation can be evaluated in real time. As a result, it is monitored if the timber (log) is turned into an optimized position before entering sawing machine and if there is a need of correction of the timber's (log's) position, the scanner will instruct the log turner or the operator to do so. |
