The friction between the edge of the workpiece and the rotating tool causes a short heating locally, which acts as a form of heat treatment of the adhesive component in the fiber structure of the MDF workpiece.

Proces til kantbehandling på emner fremstillet af MDF materialeProcess for edge treatment on items made of MDF material

Herværende opfindelse omhandler en fremgangsmåde, der anvendes til at klargøre et emne fremstillet af MDF (medium density fibreboard) materiale inden emnets slutbehandling, som f.eks. kan være en lakering.The present invention relates to a method used to prepare a blank made of MDF (medium density fibreboard) material prior to finishing the blank, such as can be a lacquer.

Det er et kendt problem, al for at opnå en høj kvalitet på lakerede kantoverflader for emner fremstillet at MDF, kræves omfattende slibning, polering og sluttelig en omhyggelig lakering. Den samlede fremstillingspris for et emne baseret på MDF er stærkt påvirket af denne kantbehandling.It is a known problem, albeit to achieve a high quality of lacquered edge surfaces for items made of MDF, extensive grinding, polishing and, finally, careful lacquering is required. The overall manufacturing cost of a MDF-based item is greatly influenced by this edge treatment.

Kendt teknik JP 60220704 A beskriver en fremgangsmåde til kantbearbejdning af fiberplader, hvor en valse bliver opvarmet med en brænder og presset mod pladens kant.Prior art JP 60220704 A discloses a method for edge processing of fibreboard, wherein a roller is heated by a burner and pressed against the edge of the sheet.

Det er særdeles uhensigtsmæssigt at have åben ild i en trævareproduktion, og med den anførte fremgangsmåde er det meget vanskelig at opnå en ensartet kvalitet på de behandlede emner.It is extremely inconvenient to have open fire in a timber production, and with the method stated, it is very difficult to achieve a uniform quality of the treated items.

Formålet med herværende opfindelse er således at forsegle kanterne på en MDF plade så kantlakeringen bliver nemmere og enklere samt at der opnås en ensartet kvalitet for alle behandlede emner; behandlingen er mekanisk.The object of the present invention is thus to seal the edges of an MDF plate so that the edge coating becomes easier and simpler and that a uniform quality is achieved for all treated items; the treatment is mechanical.

Opfindelsen vil kr aftigt reducere tidsforbrug og omkostninger, som er forbundet med anvendelse af kendt teknik.The invention will significantly reduce the time and costs associated with the use of prior art.

Summarisk vil opfindelsen således medføre: • Enklere proces til slutbehandling af MDF emner.In summary, the invention will thus entail: • A simpler process for final processing of MDF blanks.

• Processen kan automatiseres i stor udstrækning.• The process can be automated to a large extent.

® Nedsat timeforbrug og dermed færre omkostninger.® Reduced hourly consumption and thus lower costs.

• Ensartet kvalitet fra serie til serie.• Uniform quality from series to series.

Opfindelsen finder anvendelse t alle produkter, hvor MDF benyttes, f.eks. men ikke begrænset til: • Møbler 2 DK 177227 B1 • Køkken- og bad inventar ® Forretningsinventar ® Udstillingsmateriel ® Skillerum ® Plader, lister og panelerThe invention applies to all products where MDF is used, e.g. but not limited to: • Furniture 2 DK 177227 B1 • Kitchen and bathroom fixtures ® Business fixtures ® Exhibition materials ® Exhibition rooms ® Plates, moldings and panels

Materialet MDF er meget anvendt i træindustrien til fremstilling af blandt andet møbler, skabe og inventar. MDF er fremstillet af line træfibre og med lim som bindemiddel.The material MDF is widely used in the wood industry for the manufacture of furniture, cabinets and furniture. MDF is made from line wood fibers and with glue as a binder.

Materialet er relativt nemt at forarbejde og ved gennemskæring efterlades en stabil struktur, der kan slutbearbejdes til en acceptabel produktkvalitet. En meget anvendt efterbehandling er slibning, spartling og polering afsluttet med lakering.The material is relatively easy to process and, when cut, leaves a stable structure that can be finished to an acceptable product quality. A widely used finishing is sanding, sanding and polishing finished with varnish.

Den kendte metode er dog uhensigtsmæssig at integrere i et automatiseret produktionsanlæg. I poleringsfasen anvendes voksholdige komponenter, der hyppigt i en utilsigtet sideeffekt afsættes i forskellige værktøjselementer. Desuden kræver procesforløbet typisk manual håndtering i skift imellem de forskellige produktionsfaser.However, the known method is inappropriate to integrate into an automated production plant. In the polishing phase, wax-containing components are used which are frequently deposited in various tool elements in an unintended side effect. In addition, the process process typically requires manual handling in shifts between the different stages of production.

Grundet strukturen i en plade eller liste af MDF materiale, der har lim som bindemiddel, vil en vamieproces være en brugbar behandling af emnekanter, dels for at hærde og glatte kanten og dels for at opnå en homogen og tæt overflade, som er klar til lakering.Due to the structure of a sheet or list of MDF material which has glue as a binder, a vamie process will be a useful treatment of workpiece edges, partly to harden and smooth the edge and partly to obtain a homogeneous and dense surface ready for coating. .

Det er således hensigten med opfindelsen at automatisere kantbearbejdningen mest muligt, således at emnets kant vannehærdes og gøres klar til lakering, og dette uden at der skal anvendes værktøjer, hvori der indgår åben ild.It is thus the object of the invention to automate the edge machining as much as possible, so that the edge of the workpiece is water hardened and prepared for varnishing, without the use of open fire tools.

Friktionen mellem emnets kant og det roterende værktøj medfører en kort opvarmning lokalt, der virker som en form for varmebehandling af lim komponenten i MDF emnets fiber struktur.The friction between the edge of the workpiece and the rotary tool results in a short heating locally which acts as a form of heat treatment of the adhesive component of the MDF workpiece fiber structure.

Det afgørende i processen er at det roterende værktøj bevæges frem eller tilbage relativt i forhold til emnet. Dette betyder, at om emnet bevæges eller om værktøjet bevæges, opnås det samme resultat.The crucial thing in the process is that the rotary tool moves forward or backward relative to the workpiece. This means that if the workpiece is moved or the tool is moved, the same result is achieved.

For at forbedre kvaliteten af emnebearbejdningen og opnå en kontinuerlig og ensartet fremføring af værktøjet anvendes midler (16) som kan påvirke værktøjets angrebstryk mod emnet (10). Under bearbejdningen vil der således kompenseres for inhomogenitet i emnets hårdhed. Disse midler kan være en simpel fjederbelastning eller en styret hydraulisk indretning.In order to improve the quality of the workpiece work and to achieve a continuous and uniform advance of the tool, means (16) are used which can influence the tool's attack pressure against the workpiece (10). Thus, during machining, inhomogeneity in the hardness of the workpiece will be compensated. These means may be a simple spring load or a controlled hydraulic device.

Temperaturen af værktøjets (11) angrebsflade mod emnet (10) er en vigtig og afgørende faktor for at opnå en høj finish på den bearbejdede kant. Temperaturen kan måles via standard midler f.eks. ved hjælp af et optisk/termografisk eksternt måleapparat (20), eller alternativt via et indbygget termometer i værktøjets metaldel.The temperature of the tool surface (11) against the workpiece (10) is an important and decisive factor for achieving a high finish on the machined edge. The temperature can be measured by standard means e.g. by means of an optical / thermographic external measuring device (20), or alternatively via a built-in thermometer in the metal part of the tool.

I en mere avanceret procesopstilling kan der yderlige anvendes elektroniske midler (19) til en automatisk styring og optimering baseret på parametrene og arbejdspunk- 8 DK 177227 B1 terne for værktøjstryk mod emne, temperatur af værktøjet, omdrejningstal for rotation og fremføringshastighed af værktøjet.In a more advanced process set-up, electronic means (19) can be used for automatic control and optimization based on the parameters and working points for tool pressure against workpiece, temperature of the tool, speed of rotation and speed of the tool.
