Definitions

  • the present invention relates to devices for applying a coating on a surface immersed in a fluid, making it possible in particular to paint continuously in water large submerged surfaces such as the hulls of ships and more specifically has for its object such a device which makes it possible to absorb both small defects in the surface to be painted (small bumps or hollows) than larger faults (bumps and hollows whose dimensions are of the order of several centimeters per meter).
  • this comprises means for spreading the coating on the surface, movable along the latter, and means making it possible to exert a determined pressure on the spreading means so as to expel the water from the surface to be coated as it travels.
  • the spreading means consist of a cylindrical roller applied to the surface to be coated while the supply of paint takes place through a conduit opening immediately in front of the roller.
  • the spreading means consist of a set of rotating discs, the surface of each of these discs which is in contact with the surface to be coated being covered with bristles.
  • the spreading means consist of a spatula which com has two lips, the front lip being hollow.
  • a pressurized gas jet opens into the cavity delimited by the hollow front lip in order to expel water from the surface to be coated until the paint arrives in the rear cavity located between the two. lips.
  • French patent 2184352 describes a system also using one or more rotating brushes comprising, in their central part, hard bristles used to expel water from the surface to be painted and, at the periphery, more flexible bristles used to smooth paint .
  • the means for spreading the paint consist of a roller comprising an external envelope surrounding a flexible material of cellular structure.
  • the external face of the envelope is provided with bristles while the alveolar structure of the internal material allows water to enter it so that the internal pressure is equal to the external pressure regardless of the depth of immersion.
  • the paint is always brought in through a conduit opening immediately in front of the roller.
  • the roller is replaced by a shoe of which only the face in contact with the surface to be painted is provided with bristles.
  • the skid also includes an outer envelope surrounding a flexible material of cellular structure. In both cases, the flexibility of the waterproof envelope and of the internal material allows the device to easily absorb the defects of the surface as the displacement progresses.
  • French patent 2355574 describes a device comprising rotating brushes actuated by motors themselves connected to a support by leaf springs.
  • the leaf springs only allow movements of small amplitude and this device does not make it possible to absorb significant shape defects.
  • the object of the present invention is precisely a device which overcomes these drawbacks by being capable of absorbing both small bump or hollow defects as well as shape defects.
  • the device which is the subject of the invention, it, of the type of those which comprise at least one application element moving along the surface to be painted and consisting of a pad comprising a support plate and a deformable waterproof envelope, the plate and the envelope each having an internal face and an external face, the latter being in contact with the fluid in which the surface to be painted is immersed, the envelope being provided on its external face with bristles or fibers flexible friction on said surface, the support plate and the deformable envelope having a shape such that they define an interior space of the pad, the latter being associated with a rigid support cooperating with means making it possible to exert a determined pressure on the surface, is characterized in that the interior space of the pad is impermeable to the fluid in which said surface to be painted is immersed and is equipped with elastic means making it possible to deform lo wedging the envelope and in that said means for exerting a determined pressure on the surface comprises a deformable system connecting the pad to the rigid support so that the relative position of the support and the pad can vary while the latter
  • the invention solves the problem well posed, which is to absorb both small surface defects and larger shape defects, by the combined and simultaneous action of the deformable parallelogram which allows the application element to remain in contact with the surface to paint, even if it has hollows and bumps, and elastic means that allow the envelope of the application element to deform locally to match the shape of small surface defects, whether these are in hump or hollow.
  • the interior space on the pad is waterproof and does not contain anything other than said elastic means, all the drawbacks due to the penetration of paint and solvents in the cellular material are eliminated.
  • "Small defects” are understood to mean bump or hollow defects the dimensions of which are smaller than those of the shoe and it is in this sense that this expression will be used in the remainder of this text.
  • said elastic means making it possible to locally deform the casing of the shoe comprise springs, one end of which is fixed to the internal face of the plate and the other end of which exerts pressure on the internal face of the plate.
  • said deformable system comprises a deformable parallelogram comprising a set of links connecting the application element to the support by means of joints so that the relative position of the application element and of the support can vary according to the shape defects of the surface, at least one additional lever connected to the previous ones by joints and means for exerting on said deformable parallelogram a force directed in the direction of movement of the paint application element in order to exert sufficient pressure to apply it on the surface to be painted.
  • the means making it possible to exert a force on the deformable parallelogram comprise a spring connecting the additional link to the rigid support.
  • the application element 6 has the form of a pad comprising a sealed envelope 8 fixed to a support plate 10.
  • the envelope 8 has an internal face 12 and an external face 14 on which flexible bristles 16 are fixed allowing the coating to be spread over the surface 2. These can for example be nylon fibers deposited by flocking.
  • the envelope 8 has a shape such that it defines with the plate 10 a space 18 inside the shoe 6.
  • a set of springs 20 constituted by flexible metal strips, one end of which is fixed to the internal face 22 of the plate 10 while the other end, bent, exerts pressure on the face in dull 12 of the casing 8.
  • the material constituting the latter is chosen to be flexible enough so that it can deform under the action of the springs when the shoe encounters surface defects as it moves.
  • the number and arrangement of springs allow localized deformations of the flexible casing 8 both inwards and outwards of the shoe 6 and it is thus possible to absorb both small cavities and small defects in form of bumps such as the weld bead 4.
  • the paint is brought in by a set of pipes 24 opening onto the external face of the casing 8 through orifices 26.
  • the bristles located in front of the orifice 26 (the displacement doing in the direction of the arrow) have the function of removing water from the surface to be coated as and when movements while the spreading of the paint is provided by the bristles located at the rear of this orifice.
  • the figure also shows the device connecting the shoe 6 to the rigid support 28.
  • this connection is provided by a set of links forming an articulated parallelogram.
  • two links such as 30 connected on the one hand to the rigid support 28 by joints 32 fixed to one face 42 of this support and on the other hand to the shoe 6 by joints 34.
  • a third link 36 substantially parallel the support plate 10 is connected to the first links 30 by articulations 38.
  • elastic means 40 in this case a helical spring, connecting the link 36 to the rigid support 28.
  • the parallelogram formed by the links 30, the link 36 and the line passing through the joints 32 is deformed, which makes it possible to vary the relative position of the pad and of the support 28 in depending on the obstacles encountered. For example, if it is a bump, the shoe is raised and the rods 30 come in a position 30a shown in phantom in the figure. The link 36 is driven to the right, which causes the extension of the spring 40. When the bump is crossed, the assembly returns to its initial position under the effect of the tension of the spring 40, the presence of which thus allows apply pad 6 to the surface with constant pressure.
  • This arrangement makes it possible to vary the relative position of the shoe 6 and of the support 28 in large proportions and therefore easily to absorb significant shape defects (bumps or hollows of several centimeters per meter).
  • the action of the rods and of the spring 40 is supplemented by that of the springs 20 which allow the flexible envelope 8 to match the small defects of the surface 2.
  • the device according to the invention has particularly advantageous advantages since it makes it possible to absorb both small surface defects and larger defects, for example hollows and bumps in the sheet metal work.
  • Tests on a prototype showed that a sufficient and practically constant pressure was obtained to apply the pad on a surface whose defects in shape were of the order of three centimeters per meter.
