摘要： A sawmill for tree logs includes a rocking carriage to pick up fresh logs and feed them into the path of a saw blade, as well further provisions relating to improvements to infeed systems for the fresh logs, as well as to, outflow systems for transfer of sawn-off product to a production line conveyor or the like for further processing to downline processes after the first saw cuts on the fresh logs.

摘要： A computer-assisted shingle sawing method for recovery optimization using a 0-1 defect relative to the clear line, comprising the steps of taking an image of a next slab to be cut from a wood block; defining from that image, a clear line there-across; and locations of defect on that slab relative to the clear line, determining edge lines of shingles recoverable from the slab according to optimal shingle grade recovery; sawing the next slab along these edge lines, and sawing the next slab from the wood block, thereby releasing an optimum recovery of shingles from the slab. In another aspect there is provided a method for shingle recovery optimization using an optimization by inversion strategy, wherein the inclination of a parting line for cutting the next slab from the wood block is determined for optimal shingle grade recovery. There is also provided an installation for carrying out these methods.

摘要： A sawmill for sawing a log segment in two through the core thereof and a method of sawing a log in half through the core thereof. The sawmill includes a log feed conveyor configured for feeding logs to a band saw and a log positioning rig, the band saw being disposed on a movable carriage of a fixed frame, the band saw being configured for sawing a log from a first end of the log to a distal end of the log. The log positioning rig has a reciprocating cradle having a plurality of spaced-apart cradle segments. The reciprocating cradle is pivotally attached to the fixed frame, and is configured for raising or lowering the first end of the log to align the central core of the log along the length of the log with a blade of the band saw.

摘要： An apparatus for separating a sawn timber package cut from a log into main and side products during longitudinal transport thereof, having at least one separating device positioned such that, during a feed motion of the sawn timber package, it engages in a sawing gap between single- or multi-cut main product and side product and deflects the side product in a direction leading away from the main product. Two rotatably mounted conical rollers form the separating device, each having a circumferential separating edge formed by two surfaces of revolution enclosing an acute angle, and the two conical rollers are arranged on both sides of the sawn timber package and oriented such that they engage laterally into the sawing gap with respective separating edges and roll on the main product with their first surface of revolution, while deflecting the side product from the main product with their second surface of revolution.

摘要： In various embodiments, a splitter profiler apparatus may include at least one profiler head and at least one circular saw mounted to a common arbor. The circular saw may be mounted to a saw arm, and the saw arm may be coupled with an actuator that is selectively operable to move the circular saw along the arbor. The circular saw may be used in a profiling position, in which the circular saw and profiler head are in close proximity, such that the profiler head and circular saw function collectively to form a sideboard edge with a sawn finish. The circular saw may also be used in a splitting position, in which the circular saw is at a distance from the profiler, to divide the sideboard into narrower sideboards before the sideboards are sawn from the primary workpiece. Corresponding methods and systems are also described herein.

摘要： A band saw machine is adapted for cutting a lumber, and includes frame body unit, a transport unit, a hold-down unit, a cutting unit and a drive unit. The transport unit includes an endless conveyor belt extending in a front-rear direction through the frame body unit for transporting the lumber. The hold-down unit includes an endless hold-down belt extending in the front-rear direction through the frame body unit. The endless conveyor belt and the endless hold-down belt are driven by the drive unit to rotate synchronously to carry the lumber to be cut by the cutting unit.

摘要： A lumber retrieval method renders a lumber handling system readily adaptable to compensate for irregular floors, an irregular overhead track, and variable station locations. In some examples, the method involves determining a plurality of floor-to-track error values that vary based on the floor and the track deviating from being parallel to each other, recording the plurality of floor-to-track error values on a controller, and calculating a plurality of error-compensated reading via the controller based on the plurality of lumber scanned reading and the plurality of floor-to-track error values.

摘要： A lumber loading system for transferring lumber pieces. The lumber loading system comprises a driving shaft rotating about a longitudinal axis; at least one lumber piece grasping assembly operatively connected to the driving shaft and rotating about the longitudinal axis; and a longitudinal positioning system connected to the at least one lumber piece grasping assembly. The at least one lumber piece grasping assembly is displaceable along the longitudinal axis and is operative to initially grasp a section of a corresponding lumber piece extending longitudinally substantially parallel to the longitudinal axis, temporarily maintain the section of the lumber piece and subsequently release the lumber piece. The longitudinal positioning system moves each one of the at least one lumber piece grasping assembly independently along the longitudinal axis, during rotation thereof about the longitudinal axis. A method for simultaneous loading and longitudinal displacement of successive lumber pieces is also provided.
