Abstract
Anordning og fremgangsmåte for å metallbelegge en slisset trefiberplate med et folielaminat kontinuerlig både ned i avlange slisser i platen og på platens flater mellom slissene.Platen fremflyttes i en retning på tvers av slissenes lengderetning ved bruk av en plantransportør på en ramme,. folielaminatmateriale mates kontinuerlig fra en folielaminatmaterinnretning, en roterbar valse festet til rammen og umiddelbart over transportøren roteres slik at valsens overflate ved valsens rotasjon følger overflaten til platen som fremflyttes på og av transportøren og presser folielaminatmaterialet mot platen, og valsens rotasjon drives slik at minst en langstrakt kam anordnet i valsens lengderetning posisjoneres synkront med slissen og presser folielaminatmaterialet ned i slissen. Et underliggende heftlag varmes til smelting av heftlaget. Ved etterfølgende hurtig avkjøling av metallaget unngås termisk deformasjon av belagt plate.Apparatus and method for metal coating a slotted wood fiber board with a foil laminate continuously both down into elongate slots in the board and on the boards of the board between the slots. The board is advanced in a direction transverse to the longitudinal direction of the slots using a planar conveyor on a frame. foil laminate material is fed continuously from a foil laminate feeder, a rotatable roller attached to the frame and immediately above the conveyor is rotated so that the roller surface upon rotation of the roller follows the surface of the plate being advanced on and by the conveyor and presses the foil laminate material against the plate. cam arranged in the longitudinal direction of the roller is positioned synchronously with the slot and presses the foil laminate material into the slot. An underlying adhesive layer is heated to melt the adhesive layer. Subsequent rapid cooling of the metal layer avoids thermal deformation of the coated plate.
Description
Foreliggende oppfinnelse angår en lamineringsfremgangsmåte og anordning for samme. Spesielt angår oppfinnelsen en fremgangsmåte og en anordning for å belegge en slisset eller sporet trefiberplate med et metallfolielag kontinuerlig både ned i avlange slisser eller spor i platen og på platens flater mellom slissene. The present invention relates to a lamination method and device for the same. In particular, the invention relates to a method and a device for coating a slotted or grooved wooden fiberboard with a metal foil layer continuously both down into oblong slots or grooves in the board and on the board's surfaces between the slots.
Det foreligger på markedet trefiberplater med spor for innmontering av varmekabel eller rør for vannbåren varme. Platene kan være laget av et porøst trefibermateriale for å gi god isolasjon og for å virke akustisk dempende, særlig for å dempe trinnlyder der de inngår som en del av en gulvkonstruksjon. Plater av denne type anvendes mye i bygningsindustrien, og markedet er voksende. There are wooden fiberboards on the market with grooves for installing heating cables or pipes for waterborne heating. The boards can be made of a porous wood fiber material to provide good insulation and to have an acoustic dampening effect, particularly to dampen footsteps where they are included as part of a floor construction. Sheets of this type are widely used in the building industry, and the market is growing.
Blant de ovennevnte bygningsplatetyper er det kjent en type fiberplate med spor som fortrinnsvis kan være anordnet i platens lengderetning, på tvers av platens lengderetning, eller kan omfatte spor i forskjellige retninger, hvor platen er belagt med metall. Aluminium er for en rekke bruksområder, særlig i tilknytning til bygningsformål, foretrukket som metall for platebelegg. Among the above-mentioned building board types, there is known a type of fiberboard with grooves which can preferably be arranged in the longitudinal direction of the board, across the longitudinal direction of the board, or can include grooves in different directions, where the board is coated with metal. Aluminum is for a number of applications, particularly in connection with building purposes, preferred as a metal for plate covering.
Metallbelegging av plater med spor ved en kontinuerlig fremstilling har vist seg å by på store utfordringer, både med hensyn til å oppnå en gunstig sporform etter metallbeleggingen som gjør det praktisk mulig å anbringe varmekabel eller rør i sporene og å sørge for at de holder seg på plass etter innmonteringen, og med hensyn til å fremstille belagte plater med metallbelegget ført ned i sporene med et godt produksjonsutbytte og en jevn og forutsigbar kvalitet. Metal coating of sheets with grooves in a continuous production has proven to present great challenges, both with regard to achieving a favorable groove shape after the metal coating that makes it practically possible to place heating cables or pipes in the grooves and to ensure that they stay on space after installation, and with regard to producing coated plates with the metal coating carried down into the grooves with a good production yield and a consistent and predictable quality.
Publikasjonen FR-A1-2837742 viser en anordning og fremgangsmåte for å belegge plater med metallfoliemateriale fra en metallfolie-mateinnretning, der platene følger en plantransportør, samt en roterbar valse som presser foliematerialet mot platen. The publication FR-A1-2837742 shows a device and method for coating plates with metal foil material from a metal foil feeding device, where the plates follow a plane conveyor, as well as a rotatable roller which presses the foil material against the plate.
Publikasjonen FR-A-1582284 viser en anordning og fremgangsmåte for å belegge plate med to ulike sjikt hvorav det ene kommer fra en metallfolie-mateinnretning, og der valser presser sjiktene sammen, etterfulgt av en korrugeringsanordning og en avkj ølingsanordning. The publication FR-A-1582284 shows a device and method for coating plate with two different layers, one of which comes from a metal foil feeding device, and where rollers press the layers together, followed by a corrugation device and a cooling device.
Publikasjonen FR-A-1402212 viser en anordning og fremgangsmåte for å laminere minst to sjikt, jf. fig 7, der den endelige lamineringen ses å foregå mellom valsene 82, 84 der valse 82 omfatter minst en konus som presser et øvre sjikt ned i tilsvarende konusformet utsparinger, samtidig som valsen presser sammen sjiktene mellom hver konus. Med bakgrunn i ovennevnte og andre problemer og hensikter tilveiebringer foreliggende oppfinnelse en anordning for å belegge en slisset eller sporet plate med et folielaminat kontinuerlig både ned i avlange slisser eller spor i platen og på platens flater mellom slissene eller sporene, kjennetegnet ved de trekk som fremgår av det vedfølgende patentkrav 1. The publication FR-A-1402212 shows a device and method for laminating at least two layers, cf. fig. 7, where the final lamination is seen to take place between the rollers 82, 84, where the roller 82 comprises at least one cone which presses an upper layer down in a corresponding cone-shaped recesses, while the roller presses together the layers between each cone. Against the background of the above and other problems and purposes, the present invention provides a device for coating a slotted or grooved plate with a foil laminate continuously both down into oblong slits or grooves in the plate and on the plate's surfaces between the slits or grooves, characterized by the features that appear of the attached patent claim 1.

Ved utøvelse av oppfinnelsens anordning og fremgangsmåte fremstilles eksempelvis et metallbelagt plateprodukt, fortrinnsvis bestående en Al-folie, fra et folielamineirngsmateriale 50 på rull av bredde 800mm som innbefatter 40 mikron (110g/m<2>) aluminium, en glassfibernettforsterkning (19g/m<2>) og LDPE plast for laminering av glassfibernett til aluminium (50 g/m<2>), og en porøs trefiberplater 40 av type natur porøs trefiberplate 790x590x8 mm (LxBxH) med et flertall spor eller slisser. Platen fremstilles og leveres typisk av en plateprodusent etter faste mål og med ferdigfreste spor eller slisser i platens fulle lengderetning. I en foretrukket utførelse av et metallbelagt plateprodukt omfatter platen dessuten spor beliggende langsetter platens kant men i noe avstand fira platekanten, som her omtales som sidespor. Sidesporutsparinger kan være anlagt langs en eller flere av platens kanter. De ferdigfreste spor der metallbelegget skal føres inn kan være dimensjonert til bredde 4mm +/-0.1 og byde 5mm +0/-0.5. Sidesporene (for overlegging av metallbelegg som kan perforeres) er fortrinnsvis dimensjonert til bredde 15mm og dybde 5mm +0/-0,5. By practicing the device and method of the invention, for example, a metal-coated sheet product is produced, preferably consisting of an Al foil, from a foil lamination material 50 on a roll of width 800mm which includes 40 microns (110g/m<2>) aluminium, a glass fiber net reinforcement (19g/m< 2>) and LDPE plastic for laminating glass fiber mesh to aluminum (50 g/m<2>), and a porous wood fiber board 40 of the type natural porous wood fiber board 790x590x8 mm (LxWxH) with a plurality of grooves or slots. The board is typically manufactured and delivered by a board manufacturer to fixed measurements and with pre-milled grooves or slots in the board's full length. In a preferred embodiment of a metal-coated plate product, the plate also includes grooves located along the edge of the plate but at some distance from the plate edge, which are referred to here as side grooves. Side track recesses can be laid along one or more of the board's edges. The pre-milled grooves where the metal coating is to be inserted can be dimensioned to a width of 4mm +/-0.1 and offer 5mm +0/-0.5. The side grooves (for overlaying a metal coating that can be perforated) are preferably dimensioned to a width of 15mm and a depth of 5mm +0/-0.5.
En annen foretrukket dimensjon for en porøs trefiberplate 40 som skal fremstilles ved oppfinnelsens anordning og/eller fremgangsmåte, hvilken plate er særlig velegnet som et trinnlydsdempende gulvkonstruksjonselement for bæring av en varmekabel eller et rør for transport av et oppvarmingsmedium, hvor oppvarmingsmediet fortrinnsvis er varmtvann, er 790x1183x12 mm (LxBxH). Another preferred dimension for a porous wooden fiber board 40 to be produced by the device and/or method of the invention, which board is particularly suitable as a step sound-absorbing floor construction element for carrying a heating cable or a pipe for transporting a heating medium, where the heating medium is preferably hot water, is 790x1183x12 mm (LxWxH).
I en variant av oppfinnelsen, er oppfinnelsen tilpasset til å fremstille en metallbelagt plate av de ovennevnte slag der sporene metallfolien drives ned i er dimensjonert til bredde 4mm +/-0,1 og byde 5mm +0,2/-0,3. Toleransene i denne varianten kan gi et mer optimalt utbytte ved bruk av oppfinnelsens anordning og fremgangsmåte. In a variant of the invention, the invention is adapted to produce a metal-coated plate of the above-mentioned kind where the grooves the metal foil is driven down into are dimensioned to a width of 4mm +/-0.1 and a width of 5mm +0.2/-0.3. The tolerances in this variant can give a more optimal yield when using the device and method of the invention.
En aluminiumsfolie som er forsynt med et forsterkningslag av et fibernett, eller tilsvarende forsterkning, i kombinasjon med et smeltbart plastmateriale, slik som et polyethyleneplastmateriale, anvendes fortrinnsvis til fremstilling av den metallbelagte platen i henhold til oppfinnelsens anordning og fremgangsmåte. De herværende oppfinnere har funnet at en tilpasning av oppfinnelsen til forsterket metallfolie av en type som leveres av WalkiWisa (UPM-konsernet i Finland) betegnet "Alu-folie m/plast", 165GSM ALU/COEX Plast, eller en type som leveres av Meuweissen Industrie, Nederland, betegnet "5117908021 LDPE Reinforced Alu-foil", gir et meget godt utbytte og en fremragende sluttproduktkvalitet. Disse materialer, som innbefatter et lag med smeltbart plastmateriale som ved oppfinnelsen får virkning som et smeltelim, utelukker imidlertid ikke andre folier og/eller kombinasjoner av folier, folieforsterkere, og midler til å binde eller klebe metallbelegget til platen. An aluminum foil which is provided with a reinforcing layer of a fiber net, or equivalent reinforcement, in combination with a fusible plastic material, such as a polyethylene plastic material, is preferably used for the production of the metal-coated plate according to the device and method of the invention. The present inventors have found that an adaptation of the invention to reinforced metal foil of a type supplied by WalkiWisa (the UPM group in Finland) designated "Alu foil w/plastic", 165GSM ALU/COEX Plast, or a type supplied by Meuweissen Industrie, The Netherlands, designated "5117908021 LDPE Reinforced Alu-foil", gives a very good yield and an outstanding end product quality. These materials, which include a layer of fusible plastic material which according to the invention acts as a hot-melt adhesive, do not, however, exclude other foils and/or combinations of foils, foil reinforcers, and means for binding or gluing the metal coating to the plate.
Oppfinnelsens fremstillingsanordning benytter seg fortrinnsvis av et plastmateriale som inngår som en bestanddel i et forsterkeraett til en aluminiumsfolie. Med oppfinnelsens anordning eller fremgangsmåte smeltes denne plasten "på nytt", det vil si etter at metallfolien 50 er lagt mot platen 40, og danner slik en forbindelse mellom trefiberplaten 40 og aluminiumsfolien 50. The manufacturing device of the invention preferably uses a plastic material which is included as a component in an amplifier set for an aluminum foil. With the device or method of the invention, this plastic is melted "again", i.e. after the metal foil 50 has been placed against the plate 40, thus forming a connection between the wood fiber plate 40 and the aluminum foil 50.
Ved kontinuerlig fremstilling blir platene matet inn i maskinen, fortrinnsvis fiksert butt-i-butt. Al-folien 50 blir presset og formet ved hjelp av en valse 18 forsynt med "linjaler" 28, og blir slik lagt ned på platen, og ned i sporene ved hjelp av "linjalene". Så benyttes en "varmelist" 4 for å smelte plasten slik at den forsterkete al-folien binder seg til og In continuous production, the plates are fed into the machine, preferably fixed butt-in-butt. The aluminum foil 50 is pressed and shaped with the help of a roller 18 provided with "rulers" 28, and is thus laid down on the plate, and down into the grooves with the help of the "rulers". Then a "heat strip" 4 is used to melt the plastic so that the reinforced aluminum foil binds to and
sitter fast i platen i områdene mellom sporene. is stuck in the plate in the areas between the grooves.
Rett etter varmelisten ligger det en avkjølingssone med luftkjøling for å raskt bringe temperatur i al-folien ned, hvorved det oppnås at slik at trefiberplatene ikke blir krummet som følge av termiske genererte spenninger, eller i det minste får minimalt med krumming. Immediately after the heating strip, there is a cooling zone with air cooling to quickly bring the temperature in the aluminum foil down, whereby it is achieved that the wood fiber boards are not curved as a result of thermally generated stresses, or at least get minimal curvature.
Platene blir så på slutten av produksjonslinjen delt igjen og renskåret etter behov, og lagt på pall for videre transport eller lagring. At the end of the production line, the boards are then divided again and cleaned as required, and placed on pallets for further transport or storage.
Den nye automatiske linjen som bygges i henhold til oppfinnelsen vil bestå av en lamineringsmaskin som her beskrives, fortrinnsvis bygget sammen med bearbeidingsutstyr for utfresing av sporene i platen. Det har vist seg at de toleransegrenser som en trefiberplate med forhåndsfreste spor kan ha, er store, og at maskinering av sporene rett i forkant av lamineringsmaskinen vil være svært gunstig for produksjonsutbyttet og produktets kvalitet. The new automatic line built according to the invention will consist of a laminating machine as described here, preferably built together with processing equipment for milling out the grooves in the plate. It has been shown that the tolerance limits that a wood fiber board with pre-milled grooves can have are large, and that machining the grooves right in front of the laminating machine will be very beneficial for the production yield and the quality of the product.
Selve valsen 18 som former aluminiumen ned i sporene er utformet slik at den har en diameter D som gjør at den holder folien på plass før "presskniven" 28 (her også omtalt som "linjal" 28, "pregestål" 28 eller "kam" 28), fører og presser eller driver metallfolien 50 ned i sporet. Med oppfinnelsens utforming av valse 18 og "presskniv" 28 oppnås at folien gis en gunstig fyllform, som vil bli forklart nærmere i det følgende, og slik at folien holdes behørig på plass og ikke trekkes av opp av det siste formende sporet inntil den etterfølgende festeprosessen er fullført. The roller 18 itself, which shapes the aluminum into the grooves, is designed so that it has a diameter D which means that it holds the foil in place before the "pressing knife" 28 (here also referred to as "ruler" 28, "embossing steel" 28 or "comb" 28 ), guides and presses or drives the metal foil 50 down into the groove. With the invention's design of roller 18 and "pressing knife" 28, it is achieved that the foil is given a favorable filling shape, which will be explained in more detail in the following, and so that the foil is held properly in place and is not pulled up by the last forming groove until the subsequent fastening process is completed.
For de aktuelle dimensjoner av plate og spor, er diameteren på valsen 18 er tilpasset i alt seks spor 17, hvori de nevnte "linjaler" 28 , her også omtalt som "presskniver" 28, skal anbringes, slik "linjalene" 28 ved sin innbyrdes avstand i valsen 18 passer med delingen av sporene i plate 40, dvs. avstandene mellom de aktuelle sporene i platen 40. Det vises til fig. 2a, 2b og 2c for et eksempel på valse 18 med seks spor. De vedfølgende illustrasjoner viser også anordninger for bruk av settskruer til å holde "presskniver" 28 på plass i respektive spor 17. For the relevant dimensions of plate and groove, the diameter of the roller 18 is adapted to a total of six grooves 17, in which the aforementioned "rulers" 28, here also referred to as "press knives" 28, are to be placed, as the "rulers" 28 by their mutual distance in the roller 18 matches the division of the tracks in the plate 40, i.e. the distances between the relevant tracks in the plate 40. Reference is made to fig. 2a, 2b and 2c for an example of roller 18 with six grooves. The accompanying illustrations also show devices for using set screws to hold "press knives" 28 in place in respective slots 17.
Typisk er sporene for de ovennevnte produktspesifikasjoner plassert 98,33 millimeter senter-til-senter i fra hverandre. Valsens diameter D blir da 187,8 millimeter for seks "linjaler". Lengden Ly på valsen er 800 millimeter som tilpasset til at platens ene dimensjon (lengdedimensjon) er 790 millimeter, slik det er angitt over for de to for tiden foretrukne dimensjoner av plate for metallbelegging. I valsen er det frest ut 6 spor med dybde 15 mm+1 og bredde 4mm +0,1. Dybdetoleransen tillater justeringer ved ilegging av "shim" i sporet slik at "linjalen" 17 vil skyte frem i riktig avstand fra valsens overflate. Typically, the slots for the above product specifications are spaced 98.33 millimeters center-to-center apart. The roller's diameter D then becomes 187.8 millimeters for six "rulers". The length Ly of the roller is 800 millimeters which is adjusted so that the plate's one dimension (length dimension) is 790 millimeters, as stated above for the two currently preferred dimensions of plate for metal coating. 6 grooves with a depth of 15 mm + 1 and a width of 4 mm + 0.1 are milled out in the roller. The depth tolerance allows adjustments by placing a "shim" in the groove so that the "ruler" 17 will project forward at the correct distance from the roller's surface.
I sporene i valsen er det montert "linjaler" 17 som fortrinnsvis er dannet av teflonmateriale, eller i det minste av egnet materiale med teflonliknende egenskaper, som er utformet med en "tannform" for å presse al-folien ned i sporet uten at den bringes i fast kontakt med kantene på sporet i platen. En foretrukket "tannform" fremgår av figurene 3b og 3c, hvor kammens fulle høyde er angitt ved HK som 20mm, tannhøyden er angitt ved Ht som 5mm, tannvinklen er angitt ved Vt som 11 grader, og tannradien er angitt ved Rr. Tannflatens overflatebeskaffenhet er angitt ved Sk om 1,6. Kammens lengde Lk angitt i figur 3a er 800mm. In the grooves in the roller, "rulers" 17 are mounted which are preferably made of Teflon material, or at least of suitable material with Teflon-like properties, which are designed with a "tooth shape" to press the aluminum foil down into the groove without it being brought in firm contact with the edges of the groove in the plate. A preferred "tooth shape" appears in figures 3b and 3c, where the full height of the comb is indicated by HK as 20mm, the tooth height is indicated by Ht as 5mm, the tooth angle is indicated by Vt as 11 degrees, and the tooth radius is indicated by Rr. The surface quality of the tooth surface is indicated by Sk about 1.6. The comb's length Lk indicated in Figure 3a is 800mm.
Ved anbringelse av metallfolien ned i et spor er det foretrukket å drive folien tilstrekkelig ned i sporet til en fyllform slik at det dannes et metallag i sporet som hovedsakelig følger sporets sidekanter og hvor metallaget ikke kommer i kontakt med sporets bunn. Det er særlig foretrukket at oppfinnelsens anordning og fremgangsmåte er slik tilpasset at folien anbringes nede i sporet i platen i en avstand rundt 0,5 millimeter fra sporets bunn. For oppnåelse av en slik fyllform av metallaget nede i sporet skal "linjalen" være anbrakt i valsen slik at den rager frem i en avstand som tilsvarer sporets dybde med fratrekk av rundt 0,5 millimeter. When placing the metal foil down into a slot, it is preferred to drive the foil sufficiently down into the slot into a filling shape so that a metal layer is formed in the slot which mainly follows the side edges of the slot and where the metal layer does not come into contact with the bottom of the slot. It is particularly preferred that the device and method of the invention are adapted in such a way that the foil is placed down in the groove in the plate at a distance of around 0.5 millimeters from the bottom of the groove. In order to achieve such a filling shape of the metal layer down in the groove, the "ruler" must be placed in the roller so that it protrudes a distance that corresponds to the depth of the groove minus around 0.5 millimetres.
I et foretrukket plateprodukt belagt med metall som kan henføres til en standardproduktgruppe med en rekke sporbredder som er tilpasset respektive typiske varianter av varmekabel eller varmerør for anbringelse i platens spor, og hvor metallbelegget i sporet har den ovennevnte fyllformen, er sporet fremstilt med en dybde som er lik sporbredden med et tillegg som er i området 0,5 til 1,0 millimeter. Ved å anbringe "linjalene" i valsen slik at de rager ut fra valseoverflaten i en avstand som er fra 0,0 millimeter +0,1/0,0 til 0,5 millimeter +0,l/-0,0 mindre enn spordybden oppnås at metallfolien etter anbringelse i henhold til oppfinnelsen vil befinne seg i avstand fra og uten å være i kontakt med sporets bunn. In a preferred plate product coated with metal which can be attributed to a standard product group with a number of groove widths which are adapted to respective typical variants of heating cable or heating pipe for placement in the groove of the plate, and where the metal coating in the groove has the above-mentioned filling shape, the groove is produced with a depth which is equal to the track width with an addition that is in the range of 0.5 to 1.0 millimetres. By placing the "rulers" in the roller so that they protrude from the roller surface at a distance that is from 0.0 millimeter +0.1/0.0 to 0.5 millimeter +0.l/-0.0 less than the groove depth is achieved that the metal foil after placement according to the invention will be at a distance from and without being in contact with the bottom of the track.
En hyppig anvendt varmekabel har diameter rundt 4 millimeter, og en til formålet egnet metallbelagt plate fremstilles ved oppfinnelsen fra en plate med sporbredde 4 millimeter og spordybde 5 millimeter, idet "linjalene" i valsen er montert slik at det punkt på A frequently used heating cable has a diameter of around 4 millimeters, and a metal-coated plate suitable for the purpose is produced by the invention from a plate with a groove width of 4 millimeters and a groove depth of 5 millimeters, the "rulers" in the roller being mounted so that the point on
linjalene som stikker lengst ut fra valsen befinner seg i en avstand fra valsens overflate som er fra rundt 4,3 millimeter til rundt 4,5 millimeter. Dog er den foretrukne avstanden fra valsens overflate og frem til det punkt på linjalene som stikker lengst ut fra valsen rundt 4,5 millimeter, for å sikre en avstand mellom folien i sporet og sporets bunn og samtidig å gi rom for variasjoner i sporets dybde. the rulers which protrude farthest from the roller are at a distance from the surface of the roller which is from about 4.3 millimeters to about 4.5 millimeters. However, the preferred distance from the surface of the roller to the point on the rulers that protrudes furthest from the roller is around 4.5 millimeters, to ensure a distance between the foil in the groove and the bottom of the groove and at the same time to allow for variations in the depth of the groove.
Ved andre produktspesifikasjoner modifiseres mål for valsediameter, valsebredde og spordeling, og "pressknivenes" høyde, bredde og lengde. In the case of other product specifications, measurements for roll diameter, roll width and groove pitch, and the height, width and length of the "press knives" are modified.
Når valsen roterer vil linjalen klemme fast al-folien mot fremsiden av sporet slik at draget i folien kommer mot Al-folie rull sammen med at presset fra valse gjør at allerede lagt Al-folie ligger stille. Det vises til figurene 4a og 4b som illustrerer et forløp, hvor platen i illustrasjonenes nedre del fremflyttes mot høyre og valsen samtidig roterer moturs i dreieretningen R rundt en stasjonært beliggende dreieakse 25. When the roller rotates, the ruler will clamp the Al foil against the front of the groove so that the pull in the foil comes against the Al foil roll, together with the pressure from the roller causing the already laid Al foil to lie still. Reference is made to figures 4a and 4b, which illustrate a process, where the plate in the lower part of the illustrations is moved forward to the right and the roller simultaneously rotates counter-clockwise in the direction of rotation R around a stationary axis of rotation 25.
Valsen ligger med press på 1 bar ved hjelp av luftsylinder ned mot porøsplaten. The roller lies with a pressure of 1 bar by means of an air cylinder down against the porous plate.
Der platen kommer fri av valsen ligger varmeskinnen så nær som mulig valsens ytterkant, slik at smelteprosessen av plasten på al-folien påbegynnes så raskt som mulig etter formingen og pressingen av al-folien til porøsplaten. Where the plate comes free from the roller, the heating rail is as close as possible to the outer edge of the roller, so that the melting process of the plastic on the aluminum foil begins as quickly as possible after the forming and pressing of the aluminum foil to the porous plate.
Selve varmesonen er med tilpasning til de ovennevnte mål 100 x 800 mm, og styrt med temperaturregulering. Temperaturen ligger fortrinnsvis på rundt 220 grader C med de materialer og dimensjoner som her er beskrevet. Temperaturen kan justeres imidlertid noe i henhold til produksjonslinjens fremdriftshastighet, og tilpasses slik at det oppnås best mulig vedheft mellom al-folien og porøsplaten. Nærmere bestemt oppnås den beste vedheften når plasten er smeltet og penetrert ned i porøsplaten. Varmeelementet er montert flytende slik at det til enhver tid oppnås best mulig kontakt mellom element og plate. Ved 25 g/m<2> PE-plast opereres med en temperatur på rundt 220 grader C og ved 50g/m<2> PE-plast opereres med en temperatur på rundt 280 grader C. Dette med mating av plater på 1,1 m/min. Ved å øke varmeskinnens bredde til 200mm kan det opereres med en fremflyttingshastighet for platene rundt 2,2 m/min ved de samme temperaturene. The heating zone itself is adapted to the above-mentioned dimensions of 100 x 800 mm, and controlled with temperature regulation. The temperature is preferably around 220 degrees C with the materials and dimensions described here. However, the temperature can be adjusted somewhat according to the speed of the production line, and adapted so that the best possible adhesion between the aluminum foil and the porous plate is achieved. More specifically, the best adhesion is achieved when the plastic has melted and penetrated into the porous plate. The heating element is mounted floating so that the best possible contact between element and plate is achieved at all times. At 25 g/m<2> PE plastic, the operation is at a temperature of around 220 degrees C and at 50 g/m<2> PE plastic, the operation is at a temperature of around 280 degrees C. This with feeding plates of 1.1 m/min. By increasing the width of the heating rail to 200mm, it is possible to operate with a forward speed for the plates of around 2.2 m/min at the same temperatures.
Rett i etterkant av varmesonen blir Al-folien avkjølt slik at den ikke bygger inn spenninger i platen som kan medføre krumning plate. Al-folien blir raskt avkjølt, og den smeltede plasten som fungerer som binding vil ha noe senere avkjøling og beholde formbarheten sin. Slik unngås en mulig krumming av plate som ellers kan forekomme som resultat av oppvarming/nedkjøling av Al-folie. Directly after the heating zone, the Al foil is cooled so that it does not build up stresses in the plate which could lead to plate curvature. The aluminum foil is quickly cooled, and the molten plastic that acts as a bond will have some later cooling and retain its formability. This avoids a possible curvature of the plate which can otherwise occur as a result of heating/cooling of Al foil.
Et eksempel på en fremstillingsmaskin, som i det følgende vil bli forklart med henvisning til figur 1, omfatter rullebane 1, som fortrinnsvis er en bandtransportør av 800mm bredde. Banen er en standard beltetransportør, som har en frekvensstyrt drift for transport av plater gjennom lamineringssone, en ramme 2 som utgjør et maskinstativ som beltetransportør og laminerings valse, varmeskinne og kjølesone er montert på, fotlager i antall 4stk., eksempelvis type SKF SY 25TF, hvorav to fotlager som selve formingsvalsen er montert på. Disse kan justeres slik at man kan sikre parallellitet mellom innmonterte linjaler i valse og spor i plate. To øvrige fotlager er for feste av varmeskinne. Varmeskinnen kan legges opp/ned mot laminert plate ved hjelp av handtak (Sveiehandtak) som vist ved 12. An example of a manufacturing machine, which will be explained in the following with reference to Figure 1, comprises runway 1, which is preferably a belt conveyor of 800mm width. The track is a standard belt conveyor, which has a frequency-controlled operation for the transport of plates through the lamination zone, a frame 2 which constitutes a machine stand on which the belt conveyor and lamination roller, heating rail and cooling zone are mounted, foot bearings in the number of 4, for example type SKF SY 25TF, of which two foot bearings on which the forming roller itself is mounted. These can be adjusted so that parallelism can be ensured between fitted rulers in the roller and grooves in the plate. Two other foot bearings are for attaching the heating rail. The heating rail can be placed up/down against the laminated plate using a handle (Swiehandtak) as shown at 12.
Fremstillingsmaskinen omfatter videre en varmestasjon 4, fortrinnsvis dannet av en varmeskinne i aluminium 800mm lang og lOOmm bred med innfestet et flertall varmeelementer. Denne er montert flytende slik at den ligger ned mot aluminiumsfolie slik at denne blir presset ned mot plate samtidig som varmen smelter PE plasten på baksiden av aluminiumen så denne danner lamineringssiktet mellom plate og Al.-folie. Denne varmeskinnen legges så nærme pressvals som mulig for å hindre evt. deformasjon av al-folien etter at denne er formet til platen. Umiddelbart i tilknytning til varmestasjonen har vi også montert inn en kjøleplate i stål med luftdyser som ligger rett etter varmeskinnen. Vi har her ved hjelp av en stillbar ventil mulighet til å slippe pressluft gjennom disse dyser for å lage et luftsjikt mellom laminert plate og kjøleplate. Dette for raskt å kunne kjøle aluminiumen ned etter laminering. Denne kjøleplaten fremkommer ikke på tegning da den er montert inn som resultat av testkjøring. The manufacturing machine further comprises a heating station 4, preferably formed by an aluminum heating rail 800 mm long and 100 mm wide with a plurality of heating elements attached. This is mounted floating so that it lies down against the aluminum foil so that it is pressed down against the sheet at the same time as the heat melts the PE plastic on the back of the aluminum so that this forms the lamination screen between the sheet and the aluminum foil. This heating rail is placed as close to the press roll as possible to prevent possible deformation of the aluminum foil after it has been shaped into the plate. Immediately adjacent to the heating station, we have also installed a steel cooling plate with air nozzles which is located directly behind the heating rail. Here, with the help of an adjustable valve, we have the opportunity to release compressed air through these nozzles to create an air layer between the laminated plate and the cooling plate. This is to quickly cool down the aluminum after lamination. This cooling plate does not appear on the drawing as it has been installed as a result of a test run.
Fremstillingsmaskinen omfatter videre en gjengestang 5, for justering av perforeringshjul 9. Fire muttere 6, fortrinnsvis låsemuttere, er anordnet for låsing av festebrakket for perforeringshjul. To fester 7 for hjul danner festebraketter for perforeringshjulene. Fire skiver 8 nyttes for innfesting av perforeringshjulene. To perforeringshjul 9 for perforering av 15mm langsgående spor i aluminiumen i lamineringsfolien for å markere og tilrettelegge for tilførselskabelens plassering i ferdig plate. Denne perforeringen er for at forbruker har denne å skjære etter når det er behov for å bruke dette sporet for vending/tilførsel av el-kabel ved montering. Det er meget viktig at man har aluminiumen under kabel ved vending/tilførsel av el-kabel. The manufacturing machine further comprises a threaded rod 5, for adjusting the perforation wheel 9. Four nuts 6, preferably locking nuts, are arranged for locking the fastening bracket for the perforation wheel. Two attachments 7 for wheels form attachment brackets for the perforation wheels. Four washers 8 are used for fixing the perforation wheels. Two perforation wheels 9 for perforating 15mm longitudinal grooves in the aluminum in the laminating foil to mark and facilitate the placement of the supply cable in the finished plate. This perforation is so that the consumer has this to cut when there is a need to use this slot for turning/supplying electric cable during installation. It is very important that you have the aluminum under the cable when reversing/supplying the electric cable.
Disse perforeringshjulene er runde kniver som er skjært hakk i. Videre inngår to unbrakoskruer 10 og to mutter 11 for feste av perforeirngshjul. These perforation wheels are round knives that have a notch cut in them. Furthermore, two Allen screws 10 and two nuts 11 are included for fixing the perforation wheel.
Fremstillingsmaskinen omfatter videre en løfteinnretning 12 for varmestasjonen 4. The manufacturing machine further comprises a lifting device 12 for the heating station 4.
To sfæriske lagerbukker 13 og to svivelflenser 14 inngår for oppheng av pressylindere. To sylindere 15, eksempelvis av type 1 633 70 DNC 50 Festo, for å justere press på formingsvalse og for å kunne løfte valsen ved innstilling av vals/plate/aluminium. Som angitt over har man funnet at ved 1 bar trykk i de hydrauliske/pneumatiske sylindrene av forannevnte type etableres et valsetrykk mot folie og plate hvorved det oppnås et meget godt resultat med forming og belegging av en porøs trefiberplate av det tidligere nevnte slaget. For innfesting av løfttilførsel til sylindere anvendes to flexkobling 16, eksempelvis av type 6142 FK M 16x1 5 Festo. Two spherical bearing brackets 13 and two swivel flanges 14 are included for suspension of pressure cylinders. Two cylinders 15, for example of type 1 633 70 DNC 50 Festo, to adjust pressure on the forming roller and to be able to lift the roller when setting the roller/plate/aluminium. As indicated above, it has been found that at 1 bar pressure in the hydraulic/pneumatic cylinders of the above-mentioned type, a roller pressure is established against the foil and plate, whereby a very good result is achieved with the shaping and coating of a porous wood fiber plate of the previously mentioned type. Two flex couplings 16, for example type 6142 FK M 16x1 5 Festo, are used to attach the lift supply to cylinders.
Til å drive folien inn i platens spor benyttes i den viste konstruksjonen seks "pregestål" 28. Disse er laget fortrinnsvis i plast slik at de skånsomt former aluminiumsfolien ned i spor i plater. De er til dels avsmalnende og avrundet i tverrsnitt, som vist i figurene 3a, 3b og 3c, fordi dette gir skånsom behandling av folien samt at dette er gjort for at de ikke skal ødelegge kanten av sporet på platen. To drive the foil into the plate's groove, six "embossing steels" 28 are used in the construction shown. These are preferably made of plastic so that they gently shape the aluminum foil into grooves in the plates. They are partly tapered and rounded in cross-section, as shown in figures 3a, 3b and 3c, because this provides gentle treatment of the foil and because this is done so that they do not damage the edge of the groove on the plate.
Valsen 18, som i figurene 4a og 4b ikke er tegnet i noen spesiell skala men kun er ment som illustrasjon av prinsippet, dreieaksen 25 og dreieretningen angitt ved pilen R, er anordnet med spor 17 for innfesting av pregestål 28 for forming av aluminiumen til plate. Valseomkretsen er, som angitt over, fortrinnsvis lik platebredden, og således for en foretrukket platedimensjon er omkretsen lik 590mm. I den utførelse som er gjengitt i tegningene og som er beskrevet over, veier valsen 92,4 kg, hvilket er foretrukket for å presse platene ned mot bandet 1 for å sikre god kvalitet og fremdrift gjennom lamineringsstasjonen. Vi kan her også, som angitt over, ved hjelp av sylindrene 15 legge ekstra press om nødvendig ved hjelp av stillbart trykk på sylindrene. The roller 18, which in Figures 4a and 4b is not drawn to any particular scale but is only intended as an illustration of the principle, the axis of rotation 25 and the direction of rotation indicated by the arrow R, is arranged with a groove 17 for attaching embossing steel 28 for forming the aluminum into a plate . The roller circumference is, as stated above, preferably equal to the plate width, and thus for a preferred plate dimension the circumference is equal to 590mm. In the embodiment shown in the drawings and described above, the roller weighs 92.4 kg, which is preferred for pressing the plates down against the band 1 to ensure good quality and progress through the laminating station. We can here also, as stated above, with the help of the cylinders 15 add extra pressure if necessary by means of adjustable pressure on the cylinders.
Forsyning av laminatfolie gjøres fortrinnsvis fra rull. To klosser 19 for rull er fortrinnsvis laget i nylon for å passe inn i hylse på aluminiumsrull. Dette for riktig innfesting av rull på stativ. To lagre 20, eksempelvis av type 6006 2Z SKF anvendes for å sikre at Al- rull går lett på opphengsvals 24. Vi har i tillegg montert stillbare bremser mellom stativ og nylonklosser for optimal styring/stramming av uttrekket fra Al-rullen. To segerringer 21 anvendes for låsing av lager 20. For riktig plassering av rull med aluminiumslamineringsmateriale i forhold til innmating av plater, anvendes to avstandshylser 22. To stoppringer 23 anvendes for hindring at Al- rull beveger seg på opphengsvalse 24. En blankvals 24 danner valse for oppheng av aluminiumsrull. Laminate foil is preferably supplied from a roll. Two blocks 19 for the roll are preferably made of nylon to fit into the sleeve on the aluminum roll. This is for correct fixing of the roll on the stand. Two bearings 20, for example of type 6006 2Z SKF, are used to ensure that the aluminum roller runs easily on the suspension roller 24. We have also installed adjustable brakes between the stand and nylon blocks for optimal control/tightening of the extraction from the aluminum roller. Two circlips 21 are used to lock the bearing 20. For the correct positioning of the roll with aluminum lamination material in relation to the feeding of sheets, two spacer sleeves 22 are used. Two stop rings 23 are used to prevent the aluminum roll from moving on the suspension roller 24. for hanging aluminum rolls.
Videre er styrevalser (ikke vist) montert for aluminiumsfolien, slik at den ikke vandrer i forhold til platene som mates inn. Disse er i dag manuelt justerbare, men vil bli bygd om til automatisk banestyring. Totalt er to styrevalser montert inn, hvorav en rett etter utrulling av aluminiums på stativ og en rett før Al- folien blir formpresset mot plate. Furthermore, guide rollers (not shown) are fitted for the aluminum foil, so that it does not wander in relation to the plates that are fed in. These are currently manually adjustable, but will be converted to automatic lane control. A total of two guide rollers are installed, one of which is right after the aluminum is rolled out on the stand and one right before the Al foil is pressed against the plate.
