Definitions

  • the invention relates to a method for detaching a glued covering having a closed surface with the aid of a detaching liquid. It also relates to an apparatus for performing the method.
  • Glued coverings with a closed surface can only be removed with difficulty, especially in the case of heavy versions.
  • the group of these coverings includes wallpaper-like wall coverings consisting of PVC foam plastic; PVC films with fabric backing; plucking, jute and glass fiber fabrics coated with silicate paints or emulsion paints or lacquer paints; Woodchip with multiple coats of emulsion paint; wallpaper protected with elephant skin; and ceiling panels made of foamed polystyrene.
  • Such coverings can be removed by steam jet devices, by planing, with the aid of a spatula and manual repulsion by the centimeter, by pretreating the cover with a nail roller and / or by wetting with a wallpaper stripper. Exposed adhesive residues can also be softened and removed by brushing with a paint remover.
  • the invention has for its object to provide a method and an apparatus which make it possible, in the present context, for the sake of simplicity referred to as an adhesive connecting means between the covering and the substrate, even with a heavy covering with a closed surface, to soften or detach the covering can be removed by pulling off or pushing off with the help of a spatula.
  • the solution according to the invention for the method of the type mentioned at the outset is that the release liquid is pressed airlessly and impulsively through the covering with the aid of a needle nozzle.
  • the adhesive located in the adhesive joint between the covering and the substrate is to be softened or dissolved or chemically decomposed before the mechanical separation of the covering, because the pure, airless release liquid is under sufficient pressure to penetrate the covering, e.g. B. under 100 to 400 bar, is pressed directly into the adhesive joint.
  • Airless piston or diaphragm pumps can be used to pump the release liquid at high pressure. The depth of penetration of the release liquid is therefore set by changing the pressure at the inlet of the nozzle.
  • the method is particularly effective with a slightly viscous release liquid, which improves the lifting of the covering from the surface (wedge effect).
  • a device for carrying out the method of the type mentioned in the introduction in which the release liquid is airless and pulsed through the covering with the aid of a needle nozzle is pressed through in that the needle nozzle has a valve-like nozzle opening to be connected by pressing against the covering to be detached with the supply of the detachment liquid and has a diameter of approximately 0.3 mm and that an airless conveying pressure pump is connected to the supply of the detachment liquid.
  • the nozzle opening is formed on its surface facing the covering as the covering opposite the concave half-shell.
  • a cutting ring, an O-ring, in particular made of rubber, or a flat gasket is expediently used to seal the hollow shell.
  • a handling which is favorable in terms of handling of the device for pressing the release liquid into the adhesive gap between the covering and the substrate arises if the nozzle is arranged at the end of a nozzle piston which is guided in a cylinder and is movable against a spring force and has a cavity and if the piston cavity is pressed by pressing the Piston against the spring force with the pressure supply line of the release liquid has connections to be covered.
  • This nozzle piston is to be guided with a precise fit, for example in a slotted cylinder, in order on the one hand to exactly meet the connection of the piston to the pressure line of the release liquid and on the other hand to prevent squeezing out of release liquid through the piston / cylinder seal.
  • the movable nozzle By pressing such a device against the surface to be removed, the movable nozzle is pressed into a zen cylinder.
  • the cross sections of the connection of the piston cavity with the pressure line of the release liquid opening into the cylinder come to Cover and the release liquid shoots into the surface with high pressure.
  • a recoil is exerted on the device, which pushes the device away from the wall, so that the piston is pushed out of the cylinder again by the spring force acting on it and thus the liquid supply is interrupted.
  • the device is immediately ready for the next injection.
  • two or more nozzles can also be arranged linearly or areally on a carrier element.
  • the carrier element is then expediently designed as a hollow body which is connected to the pressure line of the release liquid and which impulsively connects to the nozzles by pressing in the nozzles, that is to say by pressing the device against the covering to be removed.
  • the operator only needs to apply the force necessary to guide the device and to push the nozzle (open the nozzle against a spring).
  • the force required to press the release liquid into the adhesive gap is supplied by the connected pump due to the high liquid pressure.
  • the carrier element carrying one or more nozzles can also be resiliently suspended as a larger machine in a roller box, wherein a mechanism which in particular periodically lowers the carrier element when the box is advanced and is controlled or driven by the rollers, in particular cam mechanism, can be provided.
  • the suspension of the carrier element should be adjusted so that it pulls the carrier element upwards into the roller box in the rest position.
  • the wheels are to be coupled to the lowering mechanism of the carrier element in such a way that when the roller box is pushed, the carrier element is periodically lowered in such a way that the nozzles are pressed abruptly against the covering. By pressing the nozzles against the surface an injection of detachment fluid is triggered in each case.
  • the nozzle generally designated 1 in FIG. 1 is designed as a movable hollow nozzle piston 2 with a cavity 4 leading to the nozzle opening 3.
  • the cavity 4 has a transverse bore 5 which, when the nozzle is moved in the direction of the arrow 6, is to be covered with a pressure line 7 transporting a release liquid.
  • Reliable guidance with elastic restoring force of the nozzle piston 2 is obtained when the piston 2 is guided in a cylinder 8 with a spring 11 acting therein with a spring 11 acting on the inner piston surface 10 facing the cylinder interior 9.
  • the sealing of the line 7, which is under a pressure of, for example, 200 to 400 bar, with respect to the piston 2 or the cylinder interior 9 becomes particularly stable when the line 7 in the form of a precisely fitting socket 12 is brought up to the, for example, cylindrical surface of the nozzle piston 2.
  • a seal 14 designed as a connecting piece 13 to a handle or the like is provided on the circumference of the nozzle piston 2.
  • This seal 14 is intended to enclose the body of the nozzle 1 with a precise fit.
  • the underside of the nozzle 1 which is to be faced with the covering to be removed should be designed as a hollow shell 15 in order to ensure that the release liquid is pressed into the covering in a targeted manner.
  • a cutting ring 16 is provided in the exemplary embodiment and an O-ring, for. B. made of rubber, or a surface seal.
  • FIG. 2 shows a section through a hand-held device equipped with a plurality of nozzles 1.
  • the nozzles 1 are arranged linearly and / or flatly on a carrier element 17 of this device having a handle 18.
  • the carrier element 17 is designed as a hollow body, and its cavity is provided with a connection 19 for a high-pressure feed line of a pump which provides the release liquid.
  • the nozzles 1 movable in the direction of the arrow 6 are pressed into the carrier element 17.
  • valves of the nozzles 1 to the pressurized cavity of the carrier element 17 are opened, for example the transverse bores 5 of the nozzles 1 and the feed lines 7 (according to FIG. 1) are covered, and then the pressurized, airlessly conveyed release liquid shoots into the to be removed.
  • This "shot” results in a recoil on the device, which moves the device (against the force of the operator) away from the pad. This in turn pushes the nozzle forward by the spring 11, the liquid supply is interrupted and the device is ready for the next shot.
  • FIG. 3 shows a device designed as a machine to be pushed on the floor for detaching a glued floor covering with the aid of an airless and impulsive detachable liquid to be pressed into the adhesive joint between the covering and the substrate by needle nozzles.
  • the entire support element 17 (see. Fig. 2) in a roller box 20 resilient, z. B. hung on symbolically illustrated leaf springs 21.
  • the roller box 20 has rollers 22. Located on the underside of the carrier element 17 between the rollers 22, nozzles 1 with a vertically downwardly directed nozzle opening 3.
  • Above the carrier element 17, a cam mechanism indicated symbolically by an eccentric 23 is provided, which is coupled directly to a roller 22 of the roller box 20 via a friction wheel 24.
  • the weight of the roller box 20 can be predetermined by the choice of material. When used in the floor area, the roller box can be weighted down with a water tank or the like.
