FinScan’s auto-grading systems can be easily installed in the existing or new grading lines.
The next available update to Prologic+’s existing TrueShape scanner is GDD+, which stands for Geometrical Defect Detection. This includes new and improved TrueShape algorithms filters. There are many benefits to using Prologic+’s new GDD+ TrueShape linear scanners. After a year of development and testing, the company has improved its filtering algorithms to better use all those pixels that the new LMI Gocator 2880 provides. Scanners can now detect defects that were long ignored (or filtered) at primary and secondary breakdown. Those defects are splits, holes and catfaces. These new algorithms can be added to any existing Prologic+ TrueShape scanner. This update will result in more sawline uptime by reducing jams, and increase productivity and safety for the whole sawmill by reducing low grade material handling throughout production. Getting the new GDD+ scanner update for your primary and secondary breakdown will provides extra profits without the hassle of a complete scanner change.

GEN3 is more than just a new buzzword, it is a new way to build software. Autolog’s GEN3 software is built on a state-of-the-art architecture using all the best practices in software development. Autolog’s independency from mechanical manufacturers gives them the ability to optimize any type of primary log breakdown and to replicate any curve sawing from a downstream machine. Log rotation is an example of how the new GEN3 software can mitigate a mechanical constraint due to wear and tear. In fact, based on the known log rotation error, the optimizer will determine if the selected solution is still viable or needs to be changed for the next optimal solution.
Worldwide, over 65 industrial operations are purchasing and managing their raw material with Woodtech’s solutions. Logmeter is the ideal system for timber processing facilities that need to measure the volume and biometric characteristics of logs entering the mill safely, precisely, automatically, efficiently and in real time. Logmeter information can be communicated to log suppliers to correct log issues and improve trade. Sawmills using Logmeter have key information to optimize the price of each load based on log size and quality specifications. Pulp mills purchase fibre by measuring stereo and solid cubic volumes of loads with Logmeter.
SiCam’s canter twin or quad systems provides your mill with live size, shape and face information giving you the ability to stay on size, cut closer to target and respond to production variation immediately. SiCam’s RealTime software allows customers the ability to trend information over time, alarm when products are out of tolerance and report on information collected. SiCam can compare the data from its system with your optimizer and provide you with RealTime feedback on machine center performance. Analyzing size, face and optimizer data allows SiCam to implement its latest solution, Closed Loop Size Control. The company is able to make controlled automated adjustments to your line using this proven technology allowing your mill to stay consistently on size.
Airstar’s scanner is capable of testing horizontal and vertical LVL planks, solid timber planks and LVL formwork bearers. These products suffer from a variety of issues – structural damage, surface contaminants, rot and delaminations. Traditionally, these scaffold planks are repetitively tested by mechanical stress-load tests, causing unseen internal structural damage. Airstar hopes its system will replace the stress-load tests, ensuring safety to workers throughout the construction industry. The scanner is a version of Airstar’s leading Blow Detector, capable of penetrating all surface conditions, with varied thicknesses and material compositions.
Advances in high-speed computing have enabled USNR to apply Deep Learning to the image processors that feed its automated grading systems. The result is dramatically faster and more accurate grading solutions. Defects on this particular board are represented by the following colours: red=knots, blue=bark pockets, green=checks, and purple=skip. The foundation of accurate grading is precise defect detection. Deep Learning takes automated grading to the highest level available today. In development since 2012, USNR’s Deep Learning is currently delivering results in 58 mills around the world, with applications in the sawmill using BioVision, and the dry mill with lineal and transverse high graders.
The Linck 6 scanner allows accurate scanning of the cant curvature. An essential feature is that the cant movement is automatically recognized and reliably filtered out by the evaluating software during measuring. This results in a precise 3D-profile even if the cant was moving during the scanning process due to vibrations or other influences. The scanner can be installed right behind a machine, as it is able to efficiently recognize and correct even significant movements such as cant centering. This can considerably reduce the overall length of a sawline. Another advantage is that it can be integrated in existing sawlines, where lack of space made it impossible to install solutions available until now.
Microtec’s new Logeye 300 Stereo True Shape log scanner incorporates revolutionary new stereoscopic imaging technology to allow you to scan a vibrating, moving, or shifting log. The original true shape of the log, including sweep, is re-constructed, and thus usable for breakdown or bucking applications. By avoiding the significant capital costs of adding scan conveyor length for log stabilization, Logeye 300 Stereo opens up many possibilities for log scanning and optimization which were previously thought impossible, such as: dramatic reduction of log load to scan zone length, decreasing overall length for a single length infeed; scanning in transitions between conveyors or even directly behind the debarker; and scanning during charger rotation prior to the end-dogger or carriage.
