Definitions

  • the invention relates to a method for producing profiled elongated workpieces and at least partially coated on the lateral edge surfaces.
  • Elongated workpieces with any cross-sectional profile are coated depending on the intended use after the shaping and after finishing individual surfaces and edges.
  • the coating is either carried out over the entire surface or, especially if only the connecting surfaces or elements are coated, is restricted to partial areas, for example the lateral contact surfaces of a tongue and groove connection of strips to be arranged next to one another.
  • Such cross-sectional profiles are, for example, strips produced by extrusion or floor strips produced by milling and planing, such as laminate profiles.
  • the shaping and the coating are carried out in two separate devices by a device for post-processing. It is therefore also necessary to use at least two means of transport in which the workpieces are clamped and guided through the various devices.
  • the automatic coating of such workpieces is therefore complex and expensive.
  • the method according to the invention enables the production of elongated and at least partially coated workpieces on the lateral edge surfaces, where viscous materials can be applied to the lateral edge surfaces directly after the shaping of the workpieces and without a further finishing step.
  • the shaping and coating of the profiled workpieces can be carried out in one system, preferably one and the same means of transport guiding the material through the individual processing steps. After shaping, the workpieces can thus be coated without reclamping and without post-processing.
  • the method according to the invention is therefore time and cost-effective and can be carried out in a confined space and can be flexibly converted to the different profiles to be coated.
  • the coating device essentially consists of a housing and a coating head having a recess, in which a coating nozzle is arranged.
  • any excess coating agent can be removed again after the application by means of a vacuum which can be applied in the coating head. This step can also be carried out to set a defined layer thickness of coating agent.
  • the coating head has a recess for carrying out the edge surfaces of the elongated workpieces to be coated.
  • a coating nozzle and a means for applying vacuum to the previously coated edge surfaces are also arranged within the coating head.
  • the coating head is preferably arranged on the outside of the coating device, as a result of which a defective coating head can be replaced or converted to coating heads with differently shaped recesses in a particularly simple and quick manner.
  • the recess preferably has a contour which essentially corresponds to the cross-sectional shape of the edge surfaces to be coated.
  • a coating nozzle is arranged in the coating head.
  • the term coating nozzle is understood to mean that part of the coating device where the coating agent leaves the coating device and the application to the surfaces to be coated takes place.
  • the coating nozzle has a connection for a coating agent feed line and can have any conceivable shape that ensures that a defined volume flow of coating agent flows through.
  • Coating nozzle in the sense of the invention does not necessarily mean that the coating agent has to be finely distributed through the nozzle.
  • the coating agent can also swell out and be brought into contact with the edge surfaces to be coated.
  • the coating nozzle is preferably slit-shaped, the elongated extension of the slit preferably being transverse to the conveying direction of the surface to be coated.
  • the person skilled in the art understands that the size of the coating nozzle, in particular the size of the transfer opening, preferably the thickness of the slot, is matched to the viscosity of the coating agent, the conveying speed of the surfaces to be coated and the desired thickness of the coating.
  • the slit shape of the coating nozzle and its orientation transverse to the conveying direction of the surface to be coated ensures a coating film which is uniform and of uniform thickness over the width of the surface.
  • the coating nozzle extends essentially along the contour of the recess of the coating head. This advantageous embodiment of the invention ensures a particularly uniform application of the coating agent and a minimal loss of material which occurs exclusively when cleaning the coating head.
  • the coating agent can be, for example, lacquers or pigment-containing liquids such as paints, but also adhesives and glue or primers and impregnants. Any substance that can be applied by means of a coating nozzle and is capable of producing a film with a continuous layer thickness is encompassed by the inventive concept.
  • a means is additionally arranged within the coating head, by means of which a vacuum can be applied to the coated surfaces of the workpieces.
  • the viscous coating compositions applied by means of the coating nozzle are partially removed again by the vacuum connected downstream.
  • a defined layer thickness of the applied coating agent is set by means of the vacuum.
  • the coating agent removed again is in a chamber of the Coating device, for example using filters and / or baffle plates, deposited and collected. Such a chamber is described in DE 101 10 859.1. The corresponding description is hereby also introduced as a reference and is therefore part of the disclosure.
  • a method is provided in a particularly simple manner that is able to adjust a thickness of the coating agent layer that is adapted to the use and at the same time collects the excess material and preferably leads it in a cycle and thus leads it back to the system Provides.
  • FIGS. 1-3 The invention is described in more detail below with reference to FIGS. 1-3.

  • FIG. 1 shows the side view of a coating device 1 according to the invention.
  • the coating device 1 consists of a housing 7 and a coating head 3 arranged thereon. Lines 8 lead to the coating head 3 within the housing 7 for the inflow and outflow of coating agents and air.
  • the coating head 3 has a recess 4 for receiving the profile of the elongated workpiece 2 to be coated. With the conveying direction of the workpiece 2 running into the paper plane, the coating nozzle (not shown) and, behind it, the means for applying a vacuum (not shown) are arranged inside the coating head 3.
  • the coating agent is conveyed via the feed line 8 to the coating head 3 and applied to the lateral edge surfaces 6.
  • the coating agent removed by vacuum is in the air stream entrained and returned via the lead 8 into the housing 7 of the coating device 1.

  • the coating agent 5 is supplied with the coating agent by the pump 13 from a storage container 12. A vacuum is applied to the coated workpiece 2 behind the coating nozzle. The removed coating agent is led back to the storage container 12 via a deposition chamber (not shown) located in the coating device 1.

  • the coating agent is present as fine droplets in the air stream.

  • the deposited coating agent can be returned from the supply, for example for processing or for direct use.

  • the air flow free of coating agent finally leaves the deposition chamber 14 in the roof area of the chamber.
