Definitions

  • the present invention relates to a device for the optional conversion-free application of hotmelt adhesives, in particular PUR adhesives, and dispersion adhesives, in particular PVAc adhesives, on flat objects, in particular plate-shaped components which at least partially made of wood, wood materials, plastic or the like.
  • glue application machines which apply glue to the substrate with the aid of rollers. Such machines are so far specialized in their equipment and structural design on the type of glue to be processed. Thus, there are machines with which low-viscosity glues such as solvent adhesive or PVAc adhesives (white glues) can be applied. Furthermore, there are glue application machines, which are only suitable for the application of hot melt adhesives (hotmelts).
  • hotmelts hot melt adhesives
  • a device according to the invention is set up, optionally without hot-melt adhesives, in particular PUR adhesives, and dispersion adhesives, in particular PVAc adhesives, to be applied to flat objects without a necessary conversion.
  • the device for adhesive application to plate-shaped components which consist at least partially of wood, wood materials, plastic or the like provided.
  • the term adhesive should be understood to include the glues according to the above categories.
  • the apparatus comprises at least one applicator roll for applying the adhesive and at least one metering roller for metering the adhesive, which side by side forming a tapered gap, in which the adhesive is supplied, are arranged forming.
  • the rollers rotate, with the adhesive passing through the nip between the rollers.
  • the distance of the metering roller to the applicator roll defines the gap width, which limits the amount of adhesive that is applied to the applicator roll and from there to the workpiece. A larger gap width allows more adhesive to reach the applicator roll and thus the workpiece.
  • both a glue supply for Hot melt adhesive as well as a glue supply for Dispersion adhesive provided, which are connected via an adhesive feed system with the gap. Because both types of adhesives are stored on the device and can be supplied to it, it is possible to selectively supply one of the adhesives of the device without retooling.
  • the supply system has corresponding supply lines and valves, which allow an optional supply of a type of adhesive without retooling.
  • the applicator roll on an outer coating, in particular a rubber coating, which prevents diffusing inward of water components of the dispersion adhesive in the applicator roll.
  • the applicator roll may also be made of base materials into which the dispersion adhesives would diffuse and which would not be usable without coating.
  • the metering roller or preferably also the applicator roller is particularly preferably heated. This allows hot melt adhesives to the desired operating temperature to be heated. Furthermore, the viscosity of the adhesives can be adapted very well to the process parameters via the temperature.
  • the device has at least one adhesive seal which seals the end face between the applicator roller and the metering roller in such a way that the adhesive in the tapering gap is largely prevented from extending outward in the axial direction of the rollers.
  • two adhesive seals are provided, which seal the gap on both sides to the ends of the shafts in the axial direction of the waves. This prevents the adhesive fed into the nip, which collects there like in a kind of gutter, from running towards the ends of the rolls.
  • the gap which is formed in the profile of the sheets of the metering roller and applicator roll, are made particularly flexible and accurate, which causes a high lateral tightness.
  • the temperature of the metering roller and / or the applicator roll is controllable. Since various adhesives are to be used flexibly, this embodiment has the advantage that the temperature of the respective roller can be optimally adapted to the requirements with regard to the processing temperature of the particular adhesive.
  • two separate adhesive delivery systems are provided. This makes it particularly easy to switch between the use of the individual types of adhesive, since a cleaning of a common supply line is eliminated.
  • the structure of the applicator rubber coating prevents ingress of water constituents of the dispersion adhesive. As the adhesive change requires a thorough cleaning of the machine anyway, it is unlikely that moisture will be transferred to the PUR glue bath. Experiments have shown that the influence is not greater than it occurs anyway by the normal humidity present. Deriving from this, the invention consists in the fact that no machine components need to be replaced.
  • the invention further consists of the equipment of the metering roller with a turn-off heating.
  • the glue bath is advantageously permanently heated via the metering roller.
  • this heater is simply switched off as PVAc adhesive is processed cold.
  • PVAc dispersion adhesives
  • Another component of the invention is the equipment of the machine with two separate glue supply systems, one for PUR adhesives and one for dispersion adhesives.
  • Fig. 1 shows a schematic partial perspective view of a device 1 according to the invention for the optional conversion-free application of adhesives.
  • a workpiece 20 to be coated is arranged between an application roller 4 and a metering roller 6 on one side and a counterpressure roller 8 on the other side.
  • the application roller 4 is arranged so close to the metering roller 6 that they form a tapered gap 7.
  • adhesive 30 is arranged.
  • the workpiece 20 is conveyed in the feed direction V.
  • the application roller 4 rolls on the workpiece 20.
  • Adhesive 30 is continuously fed to the gap 7.
  • the adhesive 30 passes in a defined amount corresponding to the nip width through the nip between the applicator roll 4 and the metering roller 6 on the lower part of the applicator roll 4 and finally on the workpiece 20.
  • the workpiece 20 is coated with adhesive 30.
  • the metering roller 6 is heatable in this embodiment, to heat the adhesive 30.
  • the applicator roll 4 has an outer coating 5, here a gumming, which prevents the inward diffusion of water constituents into the applicator roll 4 when using dispersion adhesive 30.
  • An adhesive seal 10 is provided which the gap 7 between applicator roller 4 and metering roller 6 so that the adhesive 30 is prevented in the tapered gap 7 largely from running in the axial direction of the rollers 4, 6 to the outside so as to seal the front side.
  • the adhesive seal 10 consists in this embodiment of individual mutually displaceable segments 12, here plastic jaws which bear tightly against each other under pressure.
  • the supply of the adhesive 30 is determined by FIG. 2 shown.
  • Fig. 2 shows a schematic perspective view of a device 1 according to the invention for the optional conversion-free application of adhesives.
  • the delivery system 37 for adhesive 30 is shown.
  • a supply of hot melt adhesive 36 is connected to the gap 7 via a hot melt adhesive feed line 39.
  • the metering roller 6 is heated to heat the adhesive 30.
  • adhesive 30 from the Dispersion adhesive supply 35 are supplied via the supply line for dispersion adhesive 38.
  • a return line with filter system 40 for Dispersion adhesive, in particular PVAc adhesive is connected to the supply of dispersion adhesive 35 and serves for the recycling and conditioning of the adhesive.
  • the heating of the metering roller 6 is preferably switched off.
