The goal of log merchandising is to capture the highest value logs from the forest before they are shipped to downstream processing facilities for primary breakdown. Log Merchandising Scan data is used to calculate wood volume while excluding the presence of bark, determine how timber should be cross-cut into various lengths for sorting into sawlogs, veneer bolts, and pulpwood. 3D Volume Measurement A ring configuration of Gocator® sensors scans the entire circumference of the log and generates a complete 3D point cloud, revealing shape features such as taper, sweep, and crook. 360º Log Scanning Gocator® 2880 LEARN MORE Dual camera laser line profile sensors for maximum scan coverage Robust Defect Detection Gocator® scans and helps identify defects such as bark, splits, outer knots, and debarker tear-out. Complete Log Imaging Gocator® generates a height map and intensity image for total surface measurement in 3D and 2D. There are two major machine centers for log processing based on headrig or end-dogging machinery with chipper heads and multiple bandsaws. Log Optimization chroma+scan scanners are able to generate high-precision 3D data, despite the intense ambient overhead and spot lighting used in sawmills. High Ambient Light Immunity chroma+scan 2440 LEARN MORE Fast, high-sensitivity scanners with superior dynamic range Banks of chroma+scan 2440 scanners project multiple laser lines along the log length to generate 3D shape data at up to 120 Hz. The resulting 3D model is analyzed to measure shape features and compute an optimal saw solution. Determine Optimal Log Breakdown High-sensitivity with multi-exposure control delivers high-resolution scanning of low-contrast targets such as dark logs. Excellent Dark Log Performance A combination of cant edger and gangsaw systems cut cants into boards in order to achieve high-volume, high-value production. Cant Optimization chroma+scan 2430s scan at 90 Hz and are fully multiplexed to prevent scanner crosstalk, with the ability to handle up to 3 banks of scanners simultaneously. High Scan Speed with Full Multiplexing Short standoffs allow scanner placement within existing mill machinery. Small Clearance Distance LEARN MORE chroma+scan 2430 Fast, high-sensitivity scanners with superior dynamic range Multi-line laser package minimizes number of scanners to cover full board length. Tightly spaced laser lines allow for full 3D scans in just 6” of travel. Efficient Sensor Bank Design Gocator® is an all-in-one solution that combines scan, measurement, and control decision-making logic in a single device for error-proofing in various machine centers. Machine Monitoring Boards that are output from the cant edger or gangsaw are then scanned transversely in edging and trimming applications. Board Optimization Banks of Gocator® 200 scanners generate 3D profiles of each board, which are then positioned to the saw in an infeed. Based on the profile data, saws are set to extract optimal board widths. Edging Applications True Coplanar Scanning Gocator® 200 scanners provide true differential lumber thickness profiling without being affected by chain vibration or board bounce. 3D smart sensors with modular design for transverse board optimization LEARN MORE Gocator® 200 Trimming Applications Gocator® 200 scanners provide 3D data for optimal length cutting decisions. The scanners can also instruct machinery to drop out an undersized board for ripping down by a reman machine and for later re-entry into the trimmer. Gocator® is used to inspect each board as it passes by on a lugged chain deck. Finished Lumber Grading By scanning for shape, surface color, and tracheid grain angle, Gocator® 200 multi-point profile scanners generate rich data for final defect analysis and sorting by grade. Maximum Value Recovery Color Vision for Surface Defect Detection The Gocator® 200 bolt-on lightbar allows the scanner to build high-resolution color images for identifying surface defects such as splits, rot, and more. 3D smart sensors with modular design for mixing 3D profiling, tracheid, and color LEARN MORE Gocator® 200 Combining high-density 3D profiles with tracheid scanning at high scan rates allows Gocator® 250 scanners to maximize value recovery by detecting features such as grain angle, sound or unsound fiber, and blond knots.
