Abstract: A precut module with one or more profiling heads and/or circular saws may be provided upstream of a saw module. The precut module may be used to implement a portion of a cut that would otherwise be made by the saw module, thereby reducing the depth of cut required at the saw module. In some embodiments, profiling heads may be used to profile a block that is wider than a desired side board. The block may be cut from the workpiece and sent to the edger. This may provide the same or better wood volume recovery and/or throughput speed than profiling the side board or cutting the side board from a flitch. In some embodiments, cut patterns for the precut module and other machine centers may be calculated and/or selected based on a desired depth of cut at the saw module, desired throughput speed, wood volume recovery, and/or other parameters.

Abstract: Embodiments provide systems, apparatuses, and method for determining the Modulus of Elasticity (MOE) of a wood workpiece based on the travel time and/or velocity of an impact-induced acoustic stress wave. A housing may be configured to reduce extraneous acoustic waves and/or contaminants near an acoustic transducer to thereby reduce errors in the detection/identification of the acoustic stress wave. A computer system may be programmed to determine the MOE of the workpiece based on the travel time and/or velocity of multiple acoustic stress waves induced by corresponding impacts at respective locations along the end of the workpiece as the workpiece travels in a first direction. Corresponding methods and an induction system for rapidly and repeatedly striking the end of the workpiece are also described herein.

Abstract: Embodiments provide a multi-pass kiln with two or more chambers, an entrance and an exit at a proximal end of the kiln, and a reciprocal flow path extending through the kiln from the entrance to the exit. Lumber charges traveling along the reciprocal flow path may travel in a first direction along one side of the heated second chamber before traveling in a substantially opposite second direction along the opposite side of the second chamber. The distal end of the kiln may be substantially sealed, and a pressure differential between the distal end and the proximal end may draw moist heated air from the heated chamber toward the exit and entry to preheat and/or condition lumber charges traveling through the first chamber.

Abstract: Embodiments provide a pre-cut infeed system for a machine center, such as an edger. A pre-cut infeed system may include an infeed, one or more saws arranged along the infeed, and a scanner optimizer system. The scanner optimizer system may scan a workpiece and determine whether greater value can be obtained from the workpiece by cutting the workpiece transversely into two or more pieces upstream of the machine center. If so, the workpiece may be cut transversely by the saw(s) positioned along the infeed, and the cut pieces may be fed sequentially into the machine center.

Abstract: The present disclosure describes methods and systems for virtually calibrating geometric sensors with overlapping fields of view. In some embodiments, a geometric sensor may be virtually calibrated by applying a correction value to profile data obtained by the geometric sensor to generate adjusted profile data. The correction factor may be determined based at least in part on X-Y offsets and/or rotational offsets of prior profile data obtained by the geometric sensor relative to corresponding profile data obtained by a reference geometric sensor, and may be recalculated or updated as new sets of profile data are obtained. The adjusted profile data may be used in place of the original profile data in various data processing operations to functionally offset a positional error of the geometric sensor.

Abstract: Embodiments of the present disclosure provide a workpiece singulator with one or more movable stairs. A first one of the movable stairs may include an outer step member and an inner step member that is positioned between the outer step member and a second one of the movable stairs. The step members may be movable synchronously as a single stair to transport larger workpieces and asynchronously to transport smaller workpieces on the outer step member. Optionally, the workpiece singulator may further include a sensor configured to detect the size and/or position of a workpiece. In some embodiments, the workpiece singulator may be coupled with a controller configured to control the position of the outer step member independently of the position of the inner step member. In various embodiments, a workpiece singulator as disclosed herein may be operable to selectively singulate workpieces of different sizes.

Abstract: Embodiments of a self-cleaning jet tube may include an elongate hollow body that is generally rectangular in cross-section and tapered from an open first end to a second end generally opposite the first end. The elongate hollow body may have an upper wall, a lower wall, side walls, a plurality of apertures arranged along the upper wall, an end plate coupled with the walls at the second end, and at least one through-slot. A through-slot may be disposed through the end plate or a wall, between the end plate and a wall, or between two walls. The jet tube may be configured for use with the through-slot(s) open and unblocked, thereby allowing debris to be expelled from the jet tube during operation of the jet veneer dryer. Corresponding systems and method are also provided herein.

Abstract: Embodiments of an electric linear actuator may include a roller screw assembly, an electric motor coupled to the roller screw assembly, and a linear transducer operatively coupled with the roller screw assembly. The motor may be configured to drive the roller screw assembly to extend and retract another component, such as a rod. In some embodiments, the linear transducer may be configured to detect a position of the rod. The roller screw assembly may be coupled directly to the motor via a gear coupling, with the motor disposed generally in axial alignment with the roller screw assembly. Other embodiments disclosed herein include a veneer lathe carriage with electric linear actuators and corresponding apparatuses, methods, and systems.

Abstract: Embodiments provide a veneer dryer system and methods of constructing, relocating, and replacing veneer dryers and other constructs such as lumber kilns, machinery, and processing lines or parts thereof. Embodiments of a veneer dryer system may include a track and a veneer dryer movably coupled with the track. The track may extend between the desired location of the veneer dryer and a construction location. Movers may be coupled with the track at the construction location. The veneer dryer may be partially or fully constructed on the movers and moved to the desired location for use. A pre-existing veneer dryer at the desired location may remain operational during the construction and removed before the new veneer dryer is moved into place, substantially reducing downtime and costs as compared to prior methods of replacing veneer dryers.
