Log scanning system

摘要

A log stem scanning system for a bucking operation. The bucking operation includes a log deck with logs delivered laterally onto a log stem holder and from the holder onto the conveyor chain for conveying the log stems in sequence through the bucking saw. The log stem holder constitutes a component of a scanning station. An overhead support has a carriage that is guided along the holder. Scanners carried by the carriage obtain dimensional data of the vertical and lateral diameters of the log stems at selected cross sections and a laser beam transmitter on the carriage transmits the data to a stationary computer mounted at one or both ends of the scanning station.
