Definitions

  • the present invention relates to a spray applicator for applying a layer to a surface, in particular for applying an insulating material to a body panel in motor vehicle construction.
  • a nozzle body commonly used for this purpose is in DE 10 2005 013 972 A1 described.
  • This nozzle body has a convexly curved spray slot on a first end face.
  • a cavity in the form of a circular sector disk of small thickness extends from the spray slot into the nozzle body.
  • a material feed bore runs from the tip of the cavity to an opposite end face of the nozzle body.
  • the elongated spray slot forms a fan-shaped spray jet from the flow of the supplied material.
  • U.S. 3,885,741 A describes a spray applicator with several nozzle bodies which generate spray jets which are fanned out transversely to the same central plane in order to spray onto a cooling fin from different sides.
  • U.S. 2,885,741 A describes a spray nozzle arrangement with two nozzles protruding from a distributor pipe, each of which generates spray jets which are asymmetrically fanned out transversely to a central plane, the central planes of the spray nozzles crossing one another in the distributor pipe.
  • EP 1 479 293 A1 discloses a spray applicator according to the preamble of claim 1, which is intended in particular for the application of pesticides in agriculture.
  • the nozzle bodies protruding in different directions from a carrier body make this conventional one bulky and make it difficult to use in confined spaces.
  • An object of the present invention is to provide a spray applicator which is able to spray over a large angular range and which at the same time can be built compact enough to penetrate into tight spaces.
  • a spray applicator with a carrier body which has several contact surfaces, and at least two nozzle bodies, each nozzle body being attached to one of the contact surfaces and having a spray slot for generating a spray jet fanned out transversely to a central plane, and the central planes cross each other along a straight line, the straight line extends outside the support body and the contact surfaces face the straight line.
  • the straight line preferably runs through the nozzle body.
  • a material feed channel which supplies the spray slot of one of the nozzle bodies, should also run through the contact surface of the nozzle body.
  • the nozzle bodies In order to ensure efficient manufacture and maintenance of the spray applicator, e.g. To enable quick replacement of a nozzle body in the event of a blockage, the nozzle bodies should be identical to one another.
  • the nozzle bodies can be oriented in such a way that jet planes in which the spray jets of the nozzle bodies are fanned out cross one another. If the straight line in which these planes intersect runs along a surface to be coated, this simplifies the creation of a layer that is sharply delimited parallel to this straight line.
  • a spray applicator is easier to manufacture, in which the spray jets are fanned out in jet planes that are parallel to one another.
  • the distance between two nozzle bodies should be smaller than the thickness of the nozzle bodies measured along the straight line.
  • the nozzle bodies touch one another in order to minimize the distance between the jet planes;
  • a non-vanishing distance may be required in order to ensure, despite manufacturing tolerances, that one nozzle body does not occupy space that is required for the assembly of the other; this However, the distance should not be more than, for example, 1 mm.
  • the length of the contact surfaces measured transversely to the straight line should be greater than the thickness of the nozzle body measured along the straight line .
  • feet of the nozzle body resting on the contact surface should protrude from one end of a shaft of the nozzle body transversely to the straight line.
  • These feet can each have a screw hole that corresponds to a thread of the support body.
  • the distance between mutually facing ends of two spray slots can be made smaller in the applicator according to the invention than the distance between the ends of a spray slot. On the one hand, this ensures a compact design of the applicator; on the other hand, it makes it possible to make the distance between the strips deposited with the aid of the two spray slots small or, preferably, to deposit the strips without any spacing and seamlessly merging into one another.
  • the spray jets of the first and second nozzle bodies should adjoin one another as seen along the straight line.
  • a third nozzle body can be arranged on the carrier body in such a way that its spray jet overlaps the spray jets of the first and the second nozzle body.
  • Fig. 1 shows a nozzle body 1 which can be used in the spray applicator according to the invention in an exploded view.
  • a head section 2 of the nozzle body 1 comprises several plates 3, 4, 3 which are clamped between two clamping jaws 5, 6 in the assembled state.
  • the plates 3, 4,3 and clamping jaws 5, 6 are fastened with the help of screws 7 (s. Fig. 3 ) held together, which extend through the countersunk bores 8 of the clamping jaw 5 receiving the heads of the screws 7 and recesses 9 of the plates 3, 4, 3 in threaded bores 10 of the clamping jaw 6.
  • the plate 4 has a triangular recess 11 on its upper edge. Edges of the recess 11 extend symmetrically on both sides of a central plane 12, which is shown in the figure by two dash-dotted straight lines spanning them.
  • the space between the projections 13 of the two plates 3 and the recess 11 in the assembled state form a cavity extending transversely to the central plane 12, the open edge of which forms a convexly curved spray slot 14 extending between two ends 37, 38.
  • the shape of the spray slot 14 forces the sprayed material to spread in the form of a fan-shaped spray jet 19 an opening angle 2 ⁇ of z. B. 60 ° in a perpendicular to the center plane 12, to the plates 3, 4, 3 parallel beam plane 18.
  • Open-edged recesses 15 of the plates 3 and overlapping grooves 16 on the mutually facing flanks of the clamping jaws 5, 6 form the downstream end of a material feed channel 17 through which the spray slot 14 is supplied with material to be sprayed.
  • a shaft 20 adjoins the head section 2 at the bottom.
  • the material feed channel 17 extends further through the shaft 20 along its longitudinal axis 41. In the assembled state of the nozzle body 1, this longitudinal axis 41 coincides with a straight line in which the center plane 12 and the jet plane 18 intersect.
  • Feet 21 protrude in opposite directions from an end of the shaft 20 facing away from the head section 2.
  • Fig. 2 shows a perspective view of a carrier body 22.
  • a carrier body 22 From a rectangular or square base plate 23 with edge lengths I1, I2, three sockets 24, 25, 26 protrude.
  • One of these bases, here the middle 25, is cuboid with a contact surface 28 parallel to the base plate 23.
  • the other two bases 24, 26 are prism-shaped with contact surfaces 29 and 2 inclined relative to the base plate 23 and to the contact surface 28 by ⁇ and 2 ⁇ , respectively. 27.
  • Areas of the base plate 23 adjoining the narrow sides of the base 24, 26 are each provided with bores 39, which are used to attach the base plate to a shaft 40 (p. Fig. 3 ) serve.
  • the elongated rectangular contact surfaces 27-29 are provided to be placed thereon as in FIG Fig. 3 shown to assemble one of three identical nozzle bodies 1.
  • a through-hole 30 in the middle of each contact surface 27-29 is part of the material feed channel that supplies the nozzle body 1 mounted thereon 17.
  • the straight line 35 runs through the nozzle bodies 1 attached to the contact surfaces 27, 28, 29.
  • the longitudinal axes 41 of the nozzle bodies 1 coincide with the surface normals 34 of the contact surfaces 27, 28, 29, so that the (in Fig. 3 (not shown) center planes 12 of the nozzle body 1 cross each other along the straight line 35 and their jet planes 18 are perpendicular to the straight line 35.
  • the length I3 of the contact surfaces 27, 28, 29 is smaller than the edge length I2 of the base plate 23. Therefore, the base 25 extends at its in Fig. 2 and 3 the narrow side facing away from the viewer does not extend to the edge of the base plate 23, so that there, between the sockets 24, 26, in addition to the bores 39, there is space for a third bore serving for anchoring on the shaft 40.
  • Fig. 3 shows a straight line 36 that touches the projections 13 of the nozzle bodies 1 and is parallel to the straight line 35.
  • Spray slots 14 of the nozzle bodies 1 mounted on the contact surfaces 27, 28 extend on opposite sides of the plane spanned by the straight lines 35, 36.
  • the mutually facing ends 37 of these two spray slots 14 touch the straight line 36 so that, viewed in the direction of the straight lines 35, 36 and as in FIG Fig. 4 shown, the spray jets 19 of these two nozzle bodies 1 directly adjoin one another.
