Definitions

  • the invention relates to a device for applying a layer of a flowable, fine ceramic mass to a solid, continuously moving carrier with the features of the preamble of claim 1.
  • a device for producing boards from a mass of fibrous materials, in particular fiber cement, with a conveyor belt and a distribution device is known.
  • the distribution device consists of a three-sided, open at the top and bottom frame, the fourth side is closed by a freely rotatable and freely movable roller in the vertical direction except for a lower passage gap.
  • the distribution device After the interior of the frame has been filled with the mass, the distribution device is moved back and forth parallel to the direction of movement thereof in order to apply the mass in layers to the conveyor belt. This requires the distribution device to be turned over when changing the direction of movement. Since the roller can only rotate due to friction and the distribution device is moved back and forth, it runs at a constantly changing speed or stands still at the end points of the movement.
  • the thickness of the layer to be applied also depends on the speed at which the roller rotates, a completely uniform layer cannot be applied. There is also the risk that when the roller is at a standstill, particles of the mass will settle and dry on it.
  • the invention has for its object to provide a generic device that is easy to use while avoiding the disadvantages of the known device and that provides a layer of uniform thickness.
  • a solid support 2 to be coated is guided in a straight line on a guide table 1.
  • the carrier 2 which consists for example of sheet steel, is continuously moved in the direction of arrow a by known means, not shown.
  • a roller 3 is arranged above the guide table 1 and has a smooth, metallic surface and carries an axle pin 4 at each of the two ends. However, the roller 3 can also have a smooth surface made of hard rubber or plastic with low elasticity.
  • Each journal is supported in a wall 5.
  • the walls 5 arranged on both sides of the roller 3 are firmly connected to one another via a crossbar 6.
  • Each wall 5 is also pivotable about a fixed pin 7.
  • the pins 7 are arranged so that their axes are aligned with one another and run parallel to the axis of the roller 3.
  • a further wall 8 is arranged between the two walls 5 and is firmly connected to an upper part 9 of the cross-member 6.
  • the wall 8 consists of an elastically deformable material, for example sheet metal, and extends, starting from the upper part 9 of the crossbar 6, in the direction of a gap 10 between the roller 3 and the carrier 2. Grip at the end of the wall 8 facing away from the upper part several, evenly distributed over the width of the wall 8 set screws 11, each of which engages in a thread of a shoulder 12 of the crossbar 6.
  • the roller 3 forms together with the two opposite walls 5, which bear sealingly against the roller 3, and the wall 8 a storage space for the ceramic mass 13 to be applied.
  • This mass is introduced into the storage space via one or more feed pipes 14, expediently in the Way that the surface of the mass 13 is always approximately the same height.
  • the roller 3 can be driven circumferentially via one of its axle journals 4 in the direction of the arrow b.
  • the drive is advantageously designed such that the speed at which the roller 3 rotates can be changed so that a circumferential speed can be set that is equal to, greater than or less than the feed speed of the carrier.
  • An arm 16, into which a thread is cut, is provided on each of the two walls 5.
  • a set screw 17 is screwed through this thread, the lower end of which is supported on a fixed stop 18.
  • the height of the gap 10 between the roller 3 and the carrier 2 is set via the adjusting screw 17.
  • a gap 19 between the lower end of the wall 8 and the roller 3 is set to approximately the same gap height as the gap 10 by actuating the set screws 11.
  • the gap 19 can be adjusted approximately between 0 and 4 mm, so that the storage space can also be closed via the wall 8 in the event of operational interruptions.
  • the stirring cones 15 prevent skin formation on the surface of the mass 13 in the storage space. They promote the escape of trapped air and ensure an even consistency of the mass across the entire width of the storage room.
  • a roller 45 with a smooth, hard surface is provided above a guide table 43 for a carrier 44 to be coated, said roller 45 being drivable at different speeds in the direction of arrow d.
  • the roller 45 is mounted at both ends in stationary eccentric bearings 46.
  • the roller 45 in turn forms a boundary of a storage space for the mass 47 to be applied.
  • This storage space is further formed by two side walls 48 and a rear wall 49.
  • the rear wall 49 is arranged at such a distance from the roller 45 that the mass 47 located in the storage space lies directly on the carrier 44, so that its lowermost region is carried along by the carrier 44.
  • a sealing strip 50 made of a flexible material and extending over its entire width is connected, the free half of which rests on the carrier 44 during operation.
  • a doctor carrier 52 is arranged between the side walls 48 and can be pivoted about a fixed axis 51.
  • a wiper blade 53 for example made of sheet steel, is fastened to the underside of the doctor blade carrier 52 and can be adjusted by pivoting the doctor blade carrier 52 against the roller 45.
  • a plurality of adjusting screws 54 are additionally provided, which are screwed into the doctor blade carrier 52 and whose ends rest on the doctor blade 53.
  • the height of the gap 55 between the carrier 44 and the roller 45 is adjusted by rotating the eccentric bearing 46, and this predisposes the thickness of the layer to be applied.
  • the speed of the roller 45 is then set so that the desired layer thickness is achieved.
  • the layer 56 becomes thinner at a predetermined gap height 55 as the rotational speed of the roller 45 increases.
  • the doctor blade 53 ensures that the layer of mass 47 adhering to the roller surface 45 is completely doctored off. With this arrangement, too, it can be expedient to avoid a sanding effect by continuously moving the doctor blade 53 back and forth parallel to the axis of the roller 45 for a short distance.
