Systems and methods for automated cutting of lumber are disclosed. The system includes a loading module that receives lumber from a loading area and places the lumber on a cutting table. The system includes an actuating module that receives the lumber from the loading module, inspects the lumber, records lumber information based on the inspection, and positions the lumber on the cutting table in preparation for cutting. The system includes a sensor module that detects the position of the lumber on the cutting table, and records the position to the lumber information. The system includes a computing module that analyzes the lumber information received from the actuating module and sensor module. The system includes a cutting module that cuts the lumber based the lumber information, the cutting resulting in cut lumber. The system includes an unloading module that places the cut lumber on an unloading area.

Various embodiments of the present disclosure provide a lumber handling and cutting apparatus, including an incoming material conveyor assembly, a material infeed assembly adjacent to the incoming material conveyor assembly, a cutting assembly adjacent to the material infeed assembly, a material outfeed assembly adjacent to the cutting assembly, an outgoing material conveyor assembly adjacent to the cutting assembly, and a printer assembly adjacent to the incoming material conveyor assembly and the material infeed assembly.

A method for producing lumber from a tree trunk, where a machining surface is produced on the trunk by removing a slab region, and where, during a feed movement in a feed direction, the trunk moves toward at least two milling tools, which are each feedable along an infeed axis, whereby two waney regions adjacent to the machining surface are milled out and at least one side product board is profiled, and the side product board is separated from the trunk by a saw cut. During feeding and before profiling the side product board, the trunk is brought from a transport to a machining position by moving the trunk around and/or along an adjustment axis, which runs orthogonally to the feed direction, and, as a result, at least one leading region of the trunk is shifted transversely to the feed direction in the direction of at least one milling tool.

The present disclosure provides embodiments of systems and apparatuses for cutting workpieces (e.g., logs or cants) into lumber. In some embodiments, a saw module includes a saw box that is suspended from a beam, movable laterally and vertically relative to the beam, and pivotable about a vertical pivot axis. Embodiments of a chipper profiler module, an infeed module, a mid-feed module, and an outfeed module are also disclosed. A system for cutting workpiece into lumber may include any of the modules in various combinations.

A cutting device of an edge banding machine is provided, and the edge banding machine includes a conveying mechanism configured to convey a board along a first direction. The cutting device includes a base, a cutting assembly, at least one abutting assembly and a first moving mechanism. The cutting assembly includes a seat, at least one blade and a driving motor. The at least one blade is disposed on the seat and includes a plurality of cutting teeth, and each of the plurality of cutting teeth includes a first edge portion and a second edge portion, and each said second edge portion is disposed on a side of one said first edge portion and has an arcuate surface. The at least one blade is drivable to move in a second direction lateral to the first direction by the first moving mechanism.

A lumber cutting and delivery system for use in assembling trusses on a truss table includes a saw for cutting a piece of material into pieces of a truss. A trunk conveyor system receives the pieces cut from the saw. The trunk conveyor system has a first conveying element to transport the pieces over a distance in a travel direction and an ejector for discharging the pieces from the first conveying element in a first discharge direction. A branch conveyor system is configured to receive the pieces discharged from the trunk conveyor system in the first discharge direction. The branch conveyor system has a main conveying element to transport the pieces.

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.
