  • Patent number: 6971423
    Abstract: A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths.

  • Patent number: 6778680
    Abstract: A peeler block is formed previously on its opposite end faces with markings the centers of which define an optimum axis about which the block should be rotated for achieving maximum yield in peeling veneer from the block in a rotary veneer lathe. An apparatus is disclosed herein which is designed to detecting such markings at two different detecting stations and finally positioning the block such that its optimum axis is set parallel to the axes of spindles of a rotary veneer lathe is disclosed. At the first station, the markings are detected by a first pair of image sensors such as CCD cameras having lenses with a short focal length hence wide-angle viewing capability.

  • Patent number: 6763863
    Abstract: A hydraulic valve is used to judiciously shunt oil from lowering ends of the hoist and stick cylinders that have been plumbed to achieve near horizontal movement. This allows the use of cylinders that have unequal rod/bore ratios or to compensate for certain transient effects that may require the exchange of oil to the reservoir. The action of the hydraulic valve acts without obtrusive operator intervention and is essentially automatic. This allows for greater flexibility in the design of the boom system, allows the boom system to perform various tasks, while not requiring obtrusive intervention from the operator.

  • Patent number: 6705363
    Abstract: A log processor and log processing method scans a log (L) at a first station (18) so that the longitudinal centerline (32) and a sawing scheme for the log can be automatically determined by a controller (4). The log is oriented at a second station (24) so that the longitudinal centerline is oriented with respect to a vertical plane passing through the feed line. The position of the log is automatically adjusted at third and fourth stations (36, 42) so that the saw blade path (56) through the log is generally parallel to the feed line as the log passes a log exit (12) and through a saw (14). The sawing scheme can include variable tapering sawing from split taper sawing to full taper sawing. Differential steering chain assemblies (37) may be used at the fourth station and may each include continuous loop, log-engaging chains (106) which engage the log above and below the log. Log chipping, profiling heads (62) may be used on either side of the feed line, such as at a fifth station.
