State-of-the-art scan­ner boosts yield and qual­ity

Australasian Timber - - SCANNING -

GER­MAN-BASED HIT Holzin­dus­trie Tor­gau has op­ti­mized its pro­duc­tion with CT Log, the high-tech so­lu­tion for saw-in­feed and saw-line made by Mi­crotec. Af­ter 10 years of de­vel­op­ment, this is the fifth Mi­crotec flag­ship scan­ner to be in­stalled.

Large Cone-Beam tech­nol­ogy, de­vel­oped by Mi­crotec, al­lows for the first time a com­plete dig­i­tal re­con­struc­tion of the in­ter­nal char­ac­ter­is­tics of a log. The CT Log scan­ner cap­tures all de­fects and qual­ity fea­tures be­fore the break­down of the log. CT Log en­ables a per­fect saw­ing pat­tern op­ti­miza­tion, al­low­ing eval­u­a­tion of all saw­ing com­bi­na­tions that fit the qual­ity of the fi­nal prod­ucts.

The op­ti­miza­tion soft­ware de­ter­mines the saw­ing pat­tern which has the high­est added value and the re­quire­ments of the fi­nal prod­uct are con­trolled in real time ac­cord­ing to cur­rent pro­duc­tion re­quire­ments.

“This so­lu­tion will con­sid­er­ably in­crease the pro­duc­tiv­ity of the saw­line, which pro­motes a sus­tain­able pro­cess­ing of the raw ma­te­rial and im­proves the yield and the qual­ity of the fi­nal prod­ucts,“says CEO at HIT, Gün­ther Hilmer.

M icro tec’s CEO, Fed­erico Gi­u­dice­an­drea, ex­plains the tech­no­log­i­cal de­vel­op­ment of the CT Log: “Com­puted To­mog­ra­phy for logs, the CT Log, will be­come an in­dis­pens­able part of the sawmill. The trend of the wood work­ing in­dus­try is def­i­nitely mov­ing to­wards an in­crease of value and qual­ity, in­stead of quan­tity. The new­ly­de­vel­oped soft­ware for on­line saw­ing op­ti­miza­tion leads to the most pre­cise re­sults, and re­al­izes the prof­itabil­ity of the in­vest­ment in a very short time frame.”

In this spe­cific project the CT Log Com­puted To­mo­graph is equipped with the Lo­g­eye “Fin­ger­print” sys­tem for the recog­ni­tion of each log and to de­ter­mine the cor­rect an­gle. The sys­tem rec­og­nizes each log re­li­ably any time later on the saw­ing line, al­low­ing full ac­cess of the orig­i­nal CT Log scan in­for­ma­tion for saw­ing op­ti­miza­tion.

The soft­ware tool Maxi­cut sup­ports the saw­ing op­ti­miza­tion. This so­lu­tion max­i­mizes the added value of the saw­ing pat­terns by ex­am­in­ing all the pos­si­ble com­bi­na­tions of the ac­ti­vate prod­uct lists.

Mi­crotec ex­ports its prod­ucts world­wide and has branch of­fices in Linz, Venice, Mel­bourne and Van­cou­ver.

HIT Holzin­dus­trie Tor­gau was founded in 1999 in Tor­gau. Next to the mod­ern pro­duc­tion site of short wood and thin­nings, the com­pany fo­cuses on the pro­duc­tion of pal­lets, which are pro­duced ac­cord­ing to many stan­dard­ized vari­ants. The di­ver­sity of its prod­uct range in­cludes prod­ucts for the pack­ag­ing in­dus­try and wood for house, gar­den and land­scap­ing. HIT Tor­gau cur­rently has a ca­pac­ity of more than 800,000 cu­bic me­ters per year. Each day up to 120 truck­loads of stems are de­liv­ered at three cal­i­brated lo­g­yards, where the logs are clas­si­fied and de­barked. The pro­duc­tion of the pal­lets is car­ried out on 8 fully au­to­matic lines in 4 shift op­er­a­tion with a daily ca­pac­ity of 40.000 pieces.
