Definitions

  • the present invention relates to a method for processing components made of wood materials according to the preamble of claim 1.
  • Wood-based materials find a variety of applications, especially in the furniture industry, for example.
  • the wood materials used there are usually coated or painted, the term coating is used here as a generic term, which includes the painting, but also powder coating and the like. By painting or coating, the wood materials should receive an aesthetically pleasing surface.
  • the requirements have risen more and more in recent years, since the design of the furniture, for example, by high-gloss surfaces much higher demands on the coating or painting. Accordingly, the methods for producing such furniture are very complex, since a variety of individual process steps, such as grinding the wood surface, intermediate grinding of already partially painted or coated surfaces and final polishing of the finished coated or painted surfaces are required. In addition, under certain circumstances, several coating or paint layers are required, so that overall results in a very complex machining process.
  • MDF medium density fiberboard
  • abrasive such as corundum or similar abrasive elements on a support, such as a sandpaper or a grinding wheel, are arranged to rotate by means of the carrier or any other Movement forms to be moved over the surface. Due to the contact pressure exerted by the carrier, the abrasive agents cause a material removal on the surface of the component to be treated. With abrasive of a suitable grain size, this results in a fine, smooth and flat surface can be produced.
  • polishing agents again comprise abrasive particles or powders contained in an aid such as a liquid or pasty agent and by means of flexible supports such as cloth or felt disks or the like. Be moved over the surface, so that again, in turn, a corresponding material removal can be achieved by the abrasive means.
  • Such methods are particularly complex because, in particular, for the grinding or polishing steps, the corresponding component to be machined is defined in relation to the grinding or polishing process.
  • Polishing device must be arranged, which usually involves a complicated handling of the corresponding component, since a change of holder compared to the coating or Lackierbearbeitung is required.
  • the component usually has to be removed from a holder used for coating or painting and installed in a suitable for the grinding or polishing operations holder and removed accordingly after grinding or polishing and installed in another holder, resulting in a very complex handling leads. Consequently, there are also hardly any continuous machining operations involving coating and painting operations as well as grinding and polishing operations, e.g. in a so-called in-line system, possible.
  • Components made of wood materials and preferably MDF materials are made possible.
  • the corresponding method should be easy to carry out or build up and provide good results in terms of surface quality.
  • the inventors have recognized that the above-mentioned problem can be solved by employing a blasting method instead of the previously known grinding and polishing methods in which a defined contact of the abrasive means with the surface to be processed is set by means of grinding wheels or polishing plates. wherein the blasting agent to be irradiated impinge on the surface to be processed at a shallow angle.
  • the tips of the surface are removed in the same manner as in the known mechanical polishing and grinding processes and thus there is a leveling and smoothing.
  • protruding fibers are broken off by the impinging blasting means, so that no disturbing elevations are left.
  • the method according to the invention can be used particularly advantageously in connection with methods in which components are held in a single holder or holder in which they are both coated and dried and now also prepared, that is ground, or post-processed, ie polished.
  • any intermediate steps are due to the present invention in a simple manner feasible.
  • the corresponding component in the inventive method in the coating or painting of MDF boards or other wood materials, the corresponding component must be placed only in the beginning in a receptacle or holder and can then remain until final polishing in this recording or holder and all processing steps, such Priming with a primer, grinding, coating or painting in various coating steps with intermediate grinding and the like. Go through and final polishing. This leads to a very effective and efficient way of working.
  • the abrasive jet is directed onto the surface at an angle of incidence ⁇ between the surface to be treated and the main jet direction of at most 20 ° and more preferably at most 10 °. Especially angles in the range between 10 ° and 20 ° and especially between 10 ° and 15 ° have proven to be very beneficial. Since a corresponding beam from a jet nozzle or the like is usually diverged, the angle relative to the main jet direction, which represents a center line of the overall beam, is seen.
  • abrasive jet In a treatment of a component, such as a wood fiber board or MDF board, it is advantageous if, for example, all surfaces are to be treated in approximately the same quality, to direct the blasting abrasive beam on the surface to be processed so that not adjacent to the surface surfaces the blasting means are struck or do not strike the adjacent surfaces with a greater angle of incidence than the angle of incidence which the main jet occupies with the surface to be processed. This ensures that the adjacent surfaces are not damaged or worn away by the blasting media, which could happen if the blasting agents hit the adjacent surfaces at too great an angle of incidence. In certain cases, however, this may just be desired if, for example, a material compaction is to be effected on narrow end faces or corresponding edges. In this case, the abrasive jet can be easily passed over the edges or edges.
  • the surface to be machined with certain blasting abrasive rays can not be completely processed, as in the edge region of processing surface, so for example in a region in which an adjacent surface is disposed on one edge, which assigns to the Strahlstoffstrahl, that has a surface normal, which is at least a portion of the Strahlstofftechnisch vectorially opposite directed.
  • This entails the risk that this adjacent surface could be damaged by the jet of abrasive or undesirably processed.
  • a second blasting agent jet which has an opposite main jet direction, but impinges on the surface to be processed in terms of amount with the same or a similar angle of incidence.
  • This beam then necessarily impinges on the adjacent surface in the region in which the adjacent surface collides with the surface to be processed, for example in the region of an edge, since the adjacent surface lies in the beam shadow.
  • At least two blasting agent jets can be provided for each surface to be machined, which are aligned, for example, parallel to a longitudinal edge.
  • the longitudinal edge in the edge region no problems with adjacent surfaces, so that here a machining of the surface to be machined to the edge, so beyond the edge, can be made.
  • edges of the surface to be machined In the transverse to the beam direction edges of the surface to be machined, it depends on whether the edge adjacent to the adjacent surface is located in the direction of or near the blasting agent source or away from it.
  • the remote adjacent surface is in the shaded area of the blasting agent beam, so that here too processing can be done up to the edge.
  • Concerning. the blasting agent source facing edge can be maintained a safety distance, so that the processing of the surface to be machined takes place only in a spaced area.
  • grains or beads or other particles of any suitable material in particular organic and inorganic materials, such as natural products, in particular nutshells, preferably walnut shells, glass, plastic, metal, especially metal alloys, preferably steel or aluminum, sand, gravel, ceramics, oxides , Nitrides, carbides, diamond or diamond-like agents, quartz, corundum, silicon, carbide, boron nitride, dry ice, shale, whiting, tin ash, cerium oxide, or combinations thereof.
  • abrasive agents which are also used as abrasives or polishing agents.
  • the particle grains or beads may have a wide variety of sizes, and not only can a particle size distribution be present within the abrasive used, but in principle abrasive materials having different average particle sizes can be used.
  • the corresponding purpose plays a role. Grinding inserts usually use blasting agents with larger average particles or grain sizes, while in polishing applications, powders or granules with a smaller average grain size are used.
  • the blasting agent jet can be produced by a wide variety of technologies, in particular by blast wheel, compressed air, jet turbines and / or injector blasting systems.
  • the jet may comprise compressed air and / or other gases and / or liquids, in particular water or other pasty substances in addition to the abrasive agents.
  • a jet nozzle in the manner of a Venturi nozzle or a Venturi injector can be used comparable to a water jet pump in which laterally supplied abrasive agents are entrained in the stream of compressed air due to the outflow of compressed air or compressed air through a nozzle.
  • compressed air or compressed air other gases or liquids, such as water, can also be used.
  • the jet can be moved beyond the edges of the surface to be processed or, conversely, the component, so that, for example, end faces of a plate, which is usually an intersection At a larger angle incident blasting agents are additionally compressed.

  • a machined component such as an MDF board 1
  • the holder 2 can allow a suspended receiving an MDF plate 1, so that the MDF plate 1 can be moved on a rail system by a system.
  • the MDF board can be hung on hooks.
  • a plurality of jet nozzles 3 are arranged, which radiate at a shallow angle a a beam 9, the blasting agent, on the surface of the component 1.
  • FIG. 1 two opposite jet nozzles 3 are shown, which direct the beam 9 each directed towards the component 1.
  • These nozzles 3 can alternately direct rays 9 with opposite jet direction on the component, so that excess wood fibers are moved back and forth so that they break off.
  • a plurality of jet nozzles can be provided side by side with parallel or at least the same direction of rays 9, as for example in FIG. 3 can be seen in a plan view.
  • a plurality of jet arrangements 3 can be provided in particular equidistantly around the component 1.
  • the jet nozzles 3 are arranged movably, so that at least one type of movement is possible.

  • the beam 9 or the component 1 can be moved so that the beam 9 not only the entire surface of the component 1 strikes, but also adjacent end faces 19, since here by the incident beam simultaneously a compression of the Surface material takes place, which is particularly advantageous in cut plates on the cut sides.

Since the jet nozzle 3 has provided a lateral feed 4 in the area in front of the nozzle outlet, blasting agents are entrained in the compressed air jet from the blasting agent container 5, which are supplied to the lateral feed 4 via a feed line 6, and with the compressed air or the compressed air in the Beam 9 passed to the surface of the component 1.
  • the compressed air which with a pressure of up to 10 bar, usually 2 to 5 Bar is placed on the nozzle, jet speeds of about 10 m / s are set. Depending on the selected blasting medium speeds up to 90 m / s are conceivable.

  • the blasting at a shallow angle causes irregularities such as tips and the like to also be broken off and leveled, so that here too a corresponding smooth surface with few unevennesses and roughnesses is produced.
  • the corresponding blasting agents can be designed differently. For coarser machining with rougher and uneven surfaces, blasting agents with a larger grain diameter are used than in polishing processes in which correspondingly fine blasting abrasives are used.
  • FIG. 2 shows a purely schematic side view of a second embodiment of a corresponding device for the treatment of components, in particular wooden components at a flat angle of incidence.
  • the embodiment of the FIG. 2 is different from the one of FIG. 1 in that a different beam arrangement is used, while the holding device for the component 1 is identical and thus has an identical reference number to that of the exemplary embodiment of FIG. 1 ,
