Abstract
Description
527 817 C768-SE 2 och i överensstämmelse med dekor-sektionen. Positioneringen styrs eventuellt med hjälp av en dator. Pressfolien pressas mot dekorsektionen under förhöjd temperatur, eventuellt tillsammans med ett översta slitskikt arrangerat mellan dekorsektionen och pressfolien. 527 817 C768-SE 2 and in accordance with the decoration section. The positioning may be controlled by means of a computer. The press foil is pressed against the decorative section under elevated temperature, possibly together with a top wear layer arranged between the decorative section and the press foil.
Basskiktet, dekorsektionen och det eventuella slitskiktet lamineras samman under värme och tryck i en laminatpress varefier laminatpressen öppnas, laminatet tas ut ur pressen, varvid processen repeteras ett flertal gånger, varje gång med en ny omgång ytskikt men med samma pressfoliesektion. Pressfoliesektionen byts ut efter ett förutbestämt antal presscykler. Det antal gånger pressfolien kan återanvändas är mycket beroende på pressfoliens kvalitet liksom den typ av ytstruktur som finns på pressfolien. Det bör dock vara möjligt att använda varje pressfolie fifån 5 - 10 gånger, vid vissa tillfällen möjligen upp till 20 gånger. Det är fördelaktigt att använda processen för att åstadkomma dekorativa paneler där ytstrukturen samstärnmer med dekoren. Pressfolien och/eller dekorsektionen positioneras då i förhållande till varandra innan pressningen inleds.The base layer, the decorative section and the possible wear layer are laminated together under heat and pressure in a laminate press where the laminate press is opened, the laminate is taken out of the press, the process being repeated several times, each time with a new coat of surface layer but with the same press foil section. The press foil section is replaced after a predetermined number of press cycles. The number of times the press foil can be reused depends very much on the quality of the press foil as well as the type of surface structure found on the press foil. However, it should be possible to use each press foil fi 5 - 10 times, in some cases possibly up to 20 times. It is advantageous to use the process to create decorative panels where the surface structure blends in with the decor. The press foil and / or the decorative section are then positioned in relation to each other before the pressing begins.
Enligt en utföringsform av uppfinningen utgörs pressfoliesektionerna av en bana vilken matas fram en förutbestämd distans efter ett förutbestämt antal presscykler. Frarnrnatningen av pressfolien styrs lämpligen med hjälp av styrdata från sensorer vilka detekterar pressfoliens position. Dessa styrdata kan också jämföras med liknande data från sensorer som detekterar dekorens position. Sensorema är lämpligtvis ett kameraarrangernang.According to an embodiment of the invention, the press foil sections consist of a web which is fed a predetermined distance after a predetermined number of press cycles. The removal of the press foil is suitably controlled by means of control data from sensors which detect the position of the press foil. This control data can also be compared with similar data from sensors that detect the position of the decor. The sensors are suitably a camera arrangement.
Enligt en andra utfóringsform av uppfinningen utgörs pressfoliesektionema av ett ark vilket ersätts med nästa pressfolieark efier ett förutbestämt antal presseykler.According to a second embodiment of the invention, the press foil sections consist of a sheet which is replaced by the next press foil sheet or a predetermined number of press cycles.
Det är fördelaktigt att använda en färgmatriskarnera för att detektera färger medan en reflektionskarnera används för att detektera ytstruktur. Kameroma är arrangerade så att de detekterar åtminstone två motstående hörn på dekoren. Datom använder lämpligtvis erhållna data för att kalkylera en virtuell centrumpunkt för dekoren vilken används för att åstadkomma samståmmighet mellan dekor och ytstruktur. Kameroma kan också vara arrangerade så att de detekterar åtminstone två motstående höm på dekoren. Datom använder här erhållna data för att kalkylera en virtuell centrumpunkt såväl som en virtuell centrumlinje för dekoren vilka används för att åstadkomma samstämrriighet mellan dekor och ytstruktur. De data som erhålles från kontrollkarneraarrangemanget används företrädesvis av datorn för att kalkylera statistisk processtyming av tillverkningsprocessen. Passningen mellan dekor och ytstruktur kommer genom processen att radikalt förbättras. 527 817 C768-SE 3 Det är fördelaktigt att använda ett så kallat visionssystem för att styra processen. Ett sådant systern innefattar lämpligtvis ccd kameror. Det är naturligtvis möjligt att använda enklare system som till exempel fotoceller och ljusstrålar, eller till och med mekaniska system för att lokalisera kanter, hål, utbuktningar eller liknande för att identifiera och positionera de olika substraten i laminaten. Det är också fördelaktigt att använda flera olika mätpunkter på varje substrat som skall styras för att åstadkomma bästa möjliga passning. Normalt används en, eller möjligen två, närliggande kanter för positionering. Eftersom substraten är föremål för formatändring på grund av hantering, fukthalt etcetera är det fördelaktigt att använda identifieringspunkter på alla fyra kanter och sedan genom beräkning åstadkomma en virtuell rnittfixpunkt såväl som en virtuell centrumlinje vilken används vid matchning. Derma procedur kommer att säkerställa bästa möjliga matchning över hela laminatytari. Möjlig glidning mellan substraten under lamineringen kommer att mätas av mätutrustningen efter laminering. Dessa mätresultat kommer användas som en parameter vid styrning av positioneringen. Detta kommer att reducera misspassningen mellan struktur och dekor till ett Dock kommer den bästa matchningen att återfirmas längs laminatets centrumlinje.It is advantageous to use a color matrix hinge to detect colors while a reaction hinge is used to detect surface texture. The cameras are arranged so that they detect at least two opposite corners of the decor. The computer suitably uses the data obtained to calculate a virtual center point of the decor which is used to provide coherence between the decor and the surface structure. The cameras can also be arranged so that they detect at least two opposite corners on the decor. The computer uses the data obtained here to calculate a virtual center point as well as a virtual center line of the decor which are used to achieve coherence between decor and surface structure. The data obtained from the control core arrangement is preferably used by the computer to calculate statistical process control of the manufacturing process. The fit between decor and surface structure will be radically improved through the process. 527 817 C768-SE 3 It is advantageous to use a so-called vision system to control the process. Such a sister suitably includes ccd cameras. It is of course possible to use simpler systems such as photocells and light beams, or even mechanical systems to locate edges, holes, bulges or the like to identify and position the various substrates in the laminates. It is also advantageous to use olika your different measuring points on each substrate to be controlled to achieve the best possible fit. Normally one, or possibly two, adjacent edges are used for positioning. Since the substrates are subject to reshaping due to handling, moisture content, etc., it is advantageous to use identification points on all four edges and then by calculation provide a virtual cross-point as well as a virtual center line which is used for matching. This procedure will ensure the best possible match across the entire laminate surface. Possible slip between the substrates during lamination will be measured by the measuring equipment after lamination. These measurement results will be used as a parameter in controlling the positioning. This will reduce the mismatch between structure and decor to a Dock, the best match will be re-stitched along the centerline of the laminate.
Det är därför lämpligt att arrangera struktmrnönsterssektioner och dekorsektioner som har det största behovet av perfekt matchning längs larninatets centrumlinje.It is therefore convenient to arrange structural pattern sections and decorative sections which have the greatest need for perfect matching along the center line of the laminate.
Trycket i den kontinuerliga pressen är lämpligen i området 5 - 90 Bar, företrädesvis 15 - 70 Bar, medan temperaturen är 140 - 200°C, företrädesvis 160 - l80°C.The pressure in the continuous press is suitably in the range 5 - 90 Bar, preferably 15 - 70 Bar, while the temperature is 140 - 200 ° C, preferably 160 - 180 ° C.
Den dekorativa panelen innefattar lärnpligtvis ett slitskikt vilket utgörs av åtminstone en bana av cellulosa impregnerad med melaminforrnaldehydharts, vidare försedd med små aluminiumoxidpartiklar. Basskiktet utgöres lämpligen av en spånskiva med en tjocklek i området 3 - 20 mm. Enligt en föredragen utföringsforrn av uppfinningen utgörs basskiktet av en MDFskiva eller en HDFskiva med en tjocklek i området 3 - 20 mm.The decorative panel compulsorily comprises a wear layer which consists of at least one web of cellulose impregnated with melamine formaldehyde resin, further provided with small alumina particles. The base layer suitably consists of a chipboard with a thickness in the range 3 - 20 mm. According to a preferred embodiment of the invention, the base layer consists of an MDF board or an HDF board with a thickness in the range 3 - 20 mm.
Enligt en alternativ utföringsform av uppfinningen utgöres basskiktet av minst ett baspapperskikt av Krafipapper impregnerat med härdplastharts. Det erhållna laminatet limmas efter lamineringen mot en bärare a till exempel fiberskiva eller spånskiva Det är också möjligt att inkludera åtminstone ett baspappersskikt av Krafipapper impregnerat med härdplastliarts som då är arrangerat mellan basskiktet och dekorskiktet. Ett sådant basskiktet av Krafipapper är då lämpligen impregnerat med en baskatalyserad 527 817 C768-SE 4 fenolforrnaldehydharts, medan papperet i dekorskiktet är impregnerat med en syrakatalyserad melaminformaldehydharts. Dirnensionsstabiliteten kommer att bli enklare att kontrollera på grund av rnindre krympning under laminering genom denna kombination av lager varvid problem som skevning kan undvikas. Slagsegeheten kommer också att förbättras genom kombinationen ovan.According to an alternative embodiment of the invention, the base layer consists of at least one base paper layer of Kra paper impregnated with thermoset resin. The resulting laminate is glued after lamination to a carrier of, for example, a baseboard or particle board. It is also possible to include at least one base paper layer of Kra paper impregnated with thermoset sheets which are then arranged between the base layer and the decorative layer. Such a base layer of Kra paper is then suitably impregnated with a base-catalyzed phenol-formaldehyde resin, while the paper in the decorative layer is impregnated with an acid-catalyzed melamine-formaldehyde resin. Directional stability will be easier to control due to lower shrinkage during lamination through this combination of layers whereby problems such as warping can be avoided. Impact strength will also be improved by the combination above.
Dekorskiktet utgörs lämpligtvis av cellulosa impregnerad med melaminfonnaldehydharts och sträcks under impregneringen för att kompensera för krympning under lamineringsproceduren.The decorative layer is suitably made of cellulose impregnated with melamine formaldehyde resin and stretched during the impregnation to compensate for shrinkage during the lamination procedure.
Dekorskiktet är företrädesvis försett med positioneringshjälpmedel, vilka positioneringshjälpmedel är placerade i en förutbestämd position i förhållande till riktningsvariationerna i dekormönstret, att sagda positioneringshjälprnedel är avsedda att detekteras med hjälp av en kamera och ett kontrollkarneraarrangemang.The decorative layer is preferably provided with positioning aids, which positioning aids are placed in a predetermined position in relation to the directional variations in the decorative pattern, that said positioning auxiliary part are intended to be detected by means of a camera and a control core arrangement.
Det är fördelaktigt att konditionera basskiktet till en förutbestämd fukthalt och temperatur innan det förses med ett dekorskikt. Det är också fördelaktigt att konditionera dekorskiktet till en förutbestämd fiikthalt och temperatur innan det appliceras på basskiktet. Också slitskiktet är lämpligtvis konditionerat till en förutbestämd fukthalt och temperatur irman det appliceras på dekorskiktet. För att undvika skeving är det fördelaktigt att applicera åtminstone ett balansskikt på basskiktets undersida. Det är naturligtvis lämpligt att konditionera även balansskiktet till en förutbestämd fukthalt och temperatur innan det appliceras på basskiktet.It is advantageous to condition the base layer to a predetermined moisture content and temperature before it is provided with a decorative layer. It is also advantageous to condition the decorative layer to a predetermined fi content and temperature before it is applied to the base layer. The wear layer is also suitably conditioned to a predetermined moisture content and temperature before it is applied to the decorative layer. To avoid skew, it is advantageous to apply at least one balance layer to the underside of the base layer. It is of course suitable to also condition the balance layer to a predetermined moisture content and temperature before it is applied to the base layer.
