A system for detecting offsize defects and for segregating the veneer sheets containing the defects from the non-defective sheets. Scanners are positioned along the in-feed conveyor leading to the clipper. As offsize defects are identified, a computer determines which of the sheets to be cut will contain the defects. These sheets are segregated as by diverting them to a pull chain conveyor following the cutting of the sheets from the continuous sheeting. Dye is sprayed on the area of the defects as detected by the scanners to aid in further handling of the defective sheets when removed from the pull chain.

System for diverting veneer sheets having offsize defects

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.

Log scanning system

A system for processing a log or cant including chippers, profiling heads, and saws arranged as a sequence of coupled operations. Scanners and computers determine the log configuration and projected configuration of lumber pieces to be derived. One scanning function is the determination of the wane area configuration in the region of the projected side board edges. This enables a determination of the side board edges including acceptacle wane area and the desired orientation (incline or decline) of the boards relative to the path of conveyance. The profiling heads are adjustable in response to computer calculations to edge the established side boards. Stabilizing is provided and includes guide anvils positioned at the board edges following the edging operation.

Log processing systems

A system that rotatively orients and skew positions a log for lumber processing. A log is placed in centering V's and rough centered. Rotatable scan spindles rotate the log while scanners obtain measurements at spaced locations along the log length and at selected rotative positions. Each angular position is analyzed for an optimum cutting pattern and the spindles are rotated to rotate the log into the most desirable angular position. The log is skew adjusted by the scan spindles and/or knee clamps in a carriage and conveyed to a saw array. A computer controls the cutting action to achieve the selected cutting pattern.
