Definitions

  • the invention relates to a device for applying paint and / or protective liquids to a wall surface, in particular to a ship's outer wall.
  • the outer walls of ship hulls are coated with corrosion-resistant and anti-fouling coatings that have to be replaced from time to time.
  • the ships are moved into a dock and cleaned there manually and with the help of so-called jet robots (cf. DE-PS 26 57 445).
  • so-called jet robots is advantageous because the blasted paint residues can contain heavy metals and other poisons, so that manual cleaning is harmful to health in many cases.
  • the aforementioned DE-PS 26 57 445 already proposes a device that adheres to the wall surface with the help of a vacuum housing to be provided with a paint spray gun device.
  • a suitable embodiment has not been shown and is also not known to the applicant.
  • the task is therefore to create a well-known compared to a positionable holding device to be provided with a device which is suitable for applying paint and / or protective liquids to this wall surface and which can also be used in particular in combination with such movable devices in such a way that they can work both abrasively and in a manner that carries them .
  • the wall surface can be designed as a flat, inclined or vertical, essentially smooth un / or curved surface. Such surface shapes occur particularly on the outer walls of ships.
  • the ship's bottom is essentially a horizontal, smooth surface that is flat.
  • the wall surfaces of the ship's side walls are essentially slightly inclined and have a corresponding radius of curvature. There are more pronounced curves, particularly in the area of the propeller in the stern area.
  • the running track which essentially constitutes the device, is fastened to a holding device in such a way that, preferably after the abrasive work, it can immediately apply a paint so that any rust attack on the outer wall of the ship is avoided as far as possible.
  • the mounting device which generally comprises a frame that supports the other units, can be provided with the running rail on its underside or outside, but outside the frame.
  • a driven running belt is arranged along the running rail. This is guided over rollers arranged at the ends of the running rail.
  • the tool carrier is attached to the running belt and can be moved back and forth in rapid succession.
  • the running belt is preferably designed as a toothed belt and is preferably guided inside the U-profile.
  • the running rail is preferably a U-shaped profile with rail webs attached to one another and attached to the legs of the U.
  • the running rail is divided into at least two running areas for the tool carrier, so that the latter can be moved over the entire length of the running rail or over a left or right partial area. This division is done with the help of signal generators with which start and end points for the movement of the tool holder can be defined.
  • the signal transmitters are preferably installed singularly in the U-web. Inductive position transmitters, photo elements or stop switches are suitable as such signal transmitters.
  • the paint application tool is a paint spray gun that can be filled with liquid.
  • the paint application device in particular the paint roller, is fastened to a rotating arm with a first pivot axis to a limited extent by a first angle.
  • the paint roller can be pivoted through a second angle with a bracket pivotably attached to the rotating arm with a second pivot axis.
  • the paint application device in particular the paint roller, is adjustably attached to an arm, which is preferably at the same time the rotating arm, with a third pivot axis so that its distance from the running rail can be adjusted.
  • suspension devices can also be installed, so that there is an exactly definable pressing force of the paint roller on the wall surface.
  • the ship's outer wall is blasted with one or more robots.
  • the wall surface that has already been exposed is pretreated with a primer and a first coat of paint is applied during the next pass. Additional layers of paint can be created by trolleys similar in construction, which only carry the paint application device, are applied so that their painting is finished practically simultaneously with the cleaning of the ship's wall.
  • the device 100 described below for applying color and / or protective liquids on a wall surface is primarily for interaction with a blasting device, for. B. for a ship outer wall 23 processing jet robot 20, determined by suction its own weight and that of the device stops on the outer wall and is movable on this outer wall via a chassis.
  • a running rail 1 with a tool carrier 2 which can be moved back and forth on the running rail 1 via rollers 10.
  • the tool carrier 2 carries a paint application device 3, the part of which applies the paint is a paint roller 21.
  • the device 100 is suspended from below on the jet robot 20 by means of brackets 24 and can be removed or converted in a simple manner.
  • the running rail 1 is designed as a U-profile 7, on the legs 8 of which two mirror-image-arranged rail webs 9 are screwed (see FIG. 6), which ensure guidance for the guide rollers 12 of the tool carrier 2.
  • the tool carrier 2 is designed in the form of a rectangular, relatively thick plate and forms the basis for the attachment of the paint application device 3 and the necessary control elements.
  • a drive 4 of the tool holder 2 is shown schematically in FIG. 5.
  • An electric motor 16 drives an endless belt 15 through a gear 17 and a shaft 18, to which the tool holder is fastened.
  • the running belt is designed as a toothed belt.
  • the paint application device 3 consists of an arm 22 and the paint roller 21 which is pivotally attached to the end of the arm by a U-shaped bracket 25. This makes it possible to pivot the paint roller with a pivot axis 25 'which follows the surface curvature of the ship's outer wall 23 and forms an angle ⁇ with respect to the vertical plane.
  • the one to be applied Paint is supplied from a pump (not shown) through a line 26 (FIG. 7), a nipple 42 (FIG. 3) attached to the corner of the support and an elastic line 43 to the paint roller 21.
  • "Color" means any liquid that is applied to the ship's hull for protection.
  • the arm 22 is rotatably supported in a box-shaped support 28, which in turn rests on a slide 29 (see FIGS. 3 and 4) which is perpenticular with respect to the running rail 1 along the rollers 30 which are placed on the lower side of the tool carrier 2 is displaceable with a pivot axis 29 '.
  • the arm 22 is at the same time a rotary arm 19 for a limited pivoting of the paint roller 21 in its axis of rotation.
  • an angle lever 34 is placed (FIG. 4), which is pivotably moved about the axis of the rotary arm by a piston rod 35 of a cylinder 36.
  • the cylinder 36 is connected to the support 28 by a connecting piece 38, an L-profile 39 and a U-profile 41.
  • a stop prong 37 is coupled at right angles, at the free end of which the pivoting movement is transmitted.
  • the limit points of the pivoting movement tine can be set using stop screws 40.
  • the device Since the device is intended for the large wall surfaces, which can have both flat and curved surfaces, for example the planking of the bow and stern parts of a ship, the possibility of adjusting the paint roller is of great importance. It has been shown in practice that a slightly inclined adjustment of the paint roller 21 against a vertical wall allows the curved surfaces to be machined correctly during the movement of the jet robot.
  • the paint roller is pressed under a definable pressure by a spring, preferably a magnetic or air pressure spring, which is located in the area of the holder of the paint roller (not shown).
  • the desired feed of the tool holder is controlled remotely.
  • the running rail 1 is divided into several running areas 13, 13 '... by the signal transmitters 5, 5', 5 ".
  • the signal transmitters are preferably inductive proximity switches which are built into the rail webs 9 (cf. FIG. 3 It is also possible to install other switching elements, for example stop switches and the like.
  • the jet robot 20 (FIG. 7), which is suspended from safety ropes 44 and adheres to the ship's outer wall 23, carries the device 100 which, after the sandblasting and the paint removal, covers a strip 45 arranged vertically on the ship's outer wall with a layer of a primer or another coating.
  • a further running area 13 ' (FIG. 1) can be selected.
  • the start and end points of the running area 13 ' are determined by the signal generators 5' and 5 "and are determined by a control device (not shown) activated remotely.
  • the tool carrier with the paint application device moves diagonally back and forth (see FIG. 1).
  • the paint roller is pressed against the outer wall 23 of the ship with the pivot axis 22 ′.
  • the kim area (lower part of the wall shown in FIG. 2) is coated with the paint by the paint roller 21 pivoted by an angle ⁇ in accordance with the degree of curvature.
  • a horizontal strip 46 is coated, which can be seen in FIG. 8.
  • the next horizontal strip 46 'already requires a smaller angle ⁇ , which can be adjusted in accordance with the relative feed speed.
  • the pressure is ensured by a magnetic suspension of the paint roller in accordance with the curvature. Of course, the pressure is also possible using pneumatic suspension or tension suspension.
  • a paint application process with a paint roller requires an exact, often multiple coating.
  • the device has a possibility to change the position of the paint roller while working in the vertical plane with the rotating arm 19 (22) in order to ensure an overlapping, covering coating.
  • These pivoting movements with a pivot axis 21 'on the paint roller in the angular range ⁇ , which is approximately ⁇ 10 ° (see FIGS. 2 and 8), are transmitted by the rotary arm 19.
  • the function of the adjustable deflection of the rotary arm with the pivot axis 25 ' also contributes to the correct setting and the correct pressure of the paint roller relative to the wall to be coated adjust.
  • the ink roller 21 can be moved back and forth by the back and forth movement of the support 28 within the running area 13 'in a main movement with respect to the ship's outer wall by the movement of the ink roller in the direction of the ship's outer wall, i.e. Positioning on the ship's outer wall is possible at least with the pivot axis 22 '.
  • the swivel axes 21 'and 25' give the paint roller 21 two more degrees of freedom and is thus able to follow all curvatures or unevenness in the outer wall of the ship. Due to these four degrees of freedom, the paint roller is able to apply an exact, often multiple coating on the ship's outer wall with highly viscous paints of the appropriate strength without paint mist.
  • a remote control of the two main movements (moving back and forth on the running rail and moving up to the wall surface) of the paint roller is carried out by the aforementioned control devices, preferably automatically.
  • the paint is fed directly to the paint roller by a pump, which is suitable for the paints and paint media, through line 26 and an elastic line 43.
