Comact underscores 10th anniversary of GradExpertTM!
Imagine your mill has been running for 10 years without any wood grader. This is what has been going on at Resolute Forest Products in Thunder Bay (Ontario, Canada) since they trusted Comact and acquired the very first GradExpertTM, which started running in 2005. The GradExpertTM is an automated grader made to optimise geometric and vision defects found in boards without any human intervention. This breakthrough in the field of scanning and optimisation has created a new trend for grading wood in planer mills and has substantially increased their corresponding profitability. It is now feasible to have a consistent performance 24 hours a day thanks to grading solutions which take into consideration your specific grade criteria as well as how you prioritise your products!
The GradExpertTM is a combination of high-tech electronic components made to detect the geometry and the appearance of the piece of wood. Then, the system associates this piece with a grade according to these features and the given grade definition. Highresolution cameras provide a clear, accurate image of wood fiber. This accuracy is enhanced by the reading provided by the triple tracheid detection system, which measures fibre angle to thus identify defects, such as knots, decay, wood grain deviation, and pith.
This information is paired with the geometric data gathered by the laser heads and light curtain, which incidentally is a technological development designed by the Comact team of engineers. The high accuracy of the data acquired by the system’s electronic components has been made possible thanks to the fact that the Comact system offers transverse configuration. Doing so provides greater board stability through the scanner, regardless of speed (up to 260 LPM). Besides providing a more accurate measurement of the board curves, transverse configuration ensures that 100% of boards will have a solution comparable to that of linear systems.
3D Pro laser heads for linear optimisation
In 2014, Comact introduced the all-new 3D Pro laser head for linear optimisation. 3D Pro laser beams scan the piece so as to produce a geometric reconstruction which accurately reflects its composition. Owing to a scanning rate, which can vary from 300 Hz all the way to 5,000 Hz depending on the application, the 3D Pro is faster, more accurate, and more thorough than laser heads of the preceding generation. A specialized 3D Pro model is also available with tracheid effect for the purpose of detecting vision defects occurring at secondary breakdown and edging.
The 3D Pro now comes as the standard linear scanning device for Comact. Thanks to its versatility, this head is perfectly suited for log scanners as well as scanners for cants or boards to edge. Since these heads are precalibrated, they are simple to install and require very little maintenance. The all-new 3D Pro generation can also be installed on scanners of previous generations and thus give them a second life.
Comact Optimised Log Bucking System
Over the last year, Comact has noticed an uptick in the market for Optimised Log Bucking Systems. Though such systems may represent quite an investment, they allow sawmills to optimize their raw material right from the very beginning of the process and thereby benefit from increased fibre profitability.
This renewed interest comes from the installation of a Comact Optimised Log Bucking System in the Southern United States in 2015, which, by the way, will be followed by several other similar installation projects within the next two years. Therefore, Comact has grasped the opportunity to update the technology offered with this type of system.
Among the most noteworthy improvements, there is the introduction of 3D Pro laser heads—described earlier—used for scanning logs. The system comes with either shifting or fixed saws along with a lineal or transverse configuration in order to best suit client requirements. Its rugged design for southern yellow pine and high-speed applications ensures accurate positioning of stems so they are optimised according to the client’s specific criteria.
Comact’s OSC: the steadiest way to feed a profiling sawline
2015 is the year that marked the comeback of the Comact Optimised Sharp Chain. This primary breakdown feed system is equipped with a heavyduty sharp chain to provide unparalleled log stability and thereby ensure perfect log positioning when profiling sideboards. The OSC features real-time optimisation with true-shape optical scanners to allow real-time log rotation control and correction.
