摘要： In various embodiments, a scanner optimizer system may generate a virtual model of a predicted flitch based on a 3D model of a log/cant and a cut solution for the log/cant. The scanner optimizer system may compare a virtual model of an actual flitch to virtual models of predicted flitches by comparing data points at a fixed elevation relative to one or both faces of the models. Based on the comparisons, the scanner optimizer system may identify the source log from which the actual flitch was cut. In addition, the scanner optimizer system may identify the saw used to cut the actual flitch, and/or other relevant information, and use the additional information to monitor and adjust the saws and other equipment. Embodiments of corresponding apparatuses and methods are also described.

摘要： A computer-implemented method for training a software infrastructure based on machine-learning techniques to analyse data obtained from a instrumental examination of objects of a predetermined type, where each of the objects has been obtained by splitting a product into smaller pieces, wherein the software infrastructure receives, for each object in a training set, training input data comprising the data obtained from the instrumental examination and training output data comprising information on the characteristics of interest of the training object, wherein the information on the characteristics of interest is, at least in part, information that has been obtained from the results of a tomographic examination of the product from which the training object was obtained, and wherein the software infrastructure processes, through its own training unit, the training input data and the training output data for each training object in order to set internal processing parameters for the software infrastructure which correlate the training input data to the training output data.

摘要： Method and calculating unit for curve sawing of a block in a cutting direction with at least a first circular saw blade. The method comprises determining a radius of the curve sawing, by measuring the curvature of the block in the direction of cutting; calculating a vertical inclination angle of the first circular saw blade in a vertical plane relative to the cutting direction in the block, based on the determined radius of the curve sawing; inclining the first circular saw blade with the calculated vertical inclination angle; and sawing the block in the cutting direction with the inclined first circular saw blade along the determined radius of the curve sawing.

摘要： This invention relates to a process for the division of an individual input source log into discrete longitudinal lengths for subsequent processing. The process comprises receiving an individual input source log, dividing the input source log into one or a plurality of output log portions of a predetermined length, wherein at least a portion of said output log portions resultant from said division are of a substantially equal or substantially constant or consistent longitudinal length, and wherein said substantially equal or substantially constant or consistent longitudinal length output log portions are procured as a feed stream of log material for a subsequent processing step. This process provides for the processing of logs and subsequent assembly into an end product formed from a composite of sticks derived from said processed logs.

摘要： 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.

摘要： A system that includes a computer processor having a plurality of input data devices, a plurality of output data devices, and a plurality of sensors; and a mechanical assembly integrated with the computer processor to reposition a piece of wood lumber based on software code executing in the computer processor. In some embodiments, the system performs a method that includes eliciting and receiving into the computer processor data parameters from a first human user; obtaining incoming data points about the lumber from the plurality of sensors; processing and storing the data parameters; comparing the incoming data points to the data parameters to obtain comparison results; and, based on the comparison results, (1) rejecting the lumber to a preprogrammed position, (2) feeding the lumber into a saw assembly as positioned, or (3) repositioning the lumber to a more optimal position prior to feeding the lumber to the saw assembly.

摘要： A method for establishing a posteriori a match between a piece of wood and a log from which the piece of wood has been obtained, comprising the following operating steps of performing a tomographic scan of the wooden log, of calculating or selecting a log cutting pattern, of defining, starting with the tomographic information available, one or more virtual individualising characteristics which are linked to the distribution and/or size of physical characteristics of the log inside and/or on the surface of the self-same virtual piece of wood, of saving them in a database, together with information about the identity of the log, of dividing the log into real pieces of wood according to the cutting pattern, of acquiring real information about the distribution and/or size of physical characteristics of the log inside and/or on the surface of a real piece of wood and of defining corresponding real individualising characteristics to be compared with virtual individualising characteristics saved and of identifying an origin of the real piece of wood based on the information about the identity of the log which is saved together with the virtual individualising characteristics which match the real individualising characteristics.

摘要： 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.

摘要： The device has a sawing station with cross-cut saw downstream of a feed transport device feeding workpieces to a transport unit of the sawing station that has a drive separate from that of the feed transport device. The feed transport device has a retaining/accumulating unit driven independently of a transport element of the feed transport device and subjecting the workpieces to a slower supply speed than the transport element. A transfer transport device is located between retaining/accumulating unit and sawing station. The drive of the transport element of the transfer transport device is controlled/adjusted independent of or by the drive of the retaining/accumulating unit via mechanically coupled step-up gear. The workpieces initially accumulate in the feed transport device and abut each other and are then transported onward with acceleration so that they are again spaced apart. The workpiece position is detected in the region of the transfer transport device.

摘要： Sawmill auditing and control apparatus and methods employ information from one or more scan zones and/or controllers (e.g., PLCs). Boards may be logically associated with mill equipment which produced the boards, allowing defects or imperfections to be tied to certain equipment. For example, boards may be associated with a primary breakdown machine or a gangsaw, or with a pair of cutters (e.g., saws, chip heads). Such allows auditing of mill operations to identify improperly functioning machinery or out of tolerance conditions, to correct such, and/or provide notification.
