Co­mact at the fore­front of mill tech­nol­ogy

Australasian Timber - - WOODTECH -

CO­MACT IS a North Amer­i­can leader in the de­sign and man­u­fac­tur­ing of wood pro­cess­ing equip­ment. The com­pany of­fers the most com­pre­hen­sive range of prod­ucts on the mar­ket, fea­tur­ing ev­ery­thing from me­chan­i­cal equip­ment all the way to ar­ti­fi­cial vi­sion for optimisation, not to men­tion au­to­ma­tion and con­trols. Thanks to its greater ca­pa­bil­ity in sawmill de­sign, man­u­fac­tur­ing and de­liv­ery, it is one of the largest com­pa­nies of its kind in the world.

Co­mact is equipped to de­liver fully-au­to­mated pro­duc­tion lines and man­u­fac­tures equip­ment meant to meet the re­quire­ments of world­wide clients both in the soft­wood and the hard­wood pro­cess­ing busi­nesses.

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.
