Definitions

  • the invention relates to a coating wall for separating the black technical area from the gray production area of a coating pan.
  • the purpose of such a coating wall is to reduce the noise level in the room, in particular in the production area, to improve product hygiene and to prevent dust and spray mist in the room, in particular in the production area.
  • the noise generated is not only generated by the drive unit of the coating pan, but also by the movement of the raw dragees in the coating pan and the exposure to coating materials and ventilation there, which are carried out by means of probes.
  • the exposure to coating substances in the coating pan also produces dust and spray mist which have a tendency to emerge into the room from the coating pan opening.
  • the probes then had to be guided across the gray zone through the coating pan opening into the coating pan. Since the probes are subjected to constant deflections and vibrations by the raw dragées in the coating pan, a perfect seal of the probe bushings cannot be achieved by a cover plate for the coating pan opening. Probes arranged in this way also hinder cleaning work in the coating pan. Therefore, a coating wall has already been proposed, the upper part of which is drawn vertically down into the coating pan opening. Behind the coating wall, the probes should then be inserted into the coating pan opening or the coating pan are introduced. However, the disadvantage of such a solution is that it covers a considerable part of the coating pan opening; this prevents cleaning of the coating pan. Finally, essential parts of the back of the coating wall pulled down into the coating pan opening and the probe parts running there are not directly accessible for cleaning work. All of this results in poor separation of the black zone from the gray zone and reduced product hygiene.
  • the invention has for its object to provide a coating wall which leaves the coating pan opening fully accessible and thereby ensures a perfect separation of the black technology area from the gray production area in the coating pan.
  • the coating opening part of the coating wall in front of the coating pan opening is arranged correspondingly inclined to this and between the coating opening part at least and the coating pan openingY a probe to the top
  • the coating pan opening edge is arranged adjacent.
  • the coating opening part of the coating wall according to the invention cannot be arranged perpendicular to the floor, but must also be arranged inclined to the floor.
  • the inclination of the coating opening part according to the invention is steeper than that of the coating pan opening. This is the only way that probes can be arranged vertically from above into the coating pan opening or coating pan in the region of the upper edge of the coating pan opening. This probe is then arranged between the coating opening part and the coating pan opening.
  • the probe on the upper part of the coating wall according to the invention can be connected in one piece to it via a holder.
  • a collar is arranged on the coating opening part and extends over the entire circumference of the coating pan opening as far as this.
  • the opening in the coating opening part corresponds to the coating pan opening.
  • the collar is arranged to extend over the entire circumference of the opening in the coating opening part.
  • the collar now shields a cylindrical, wedge-shaped part of the space between the coating pan opening and the coating opening part.
  • the probe is guided through the collar in the area of the upper collar edge.
  • the probe can be made rigid; this gives the probe an additional hold.
  • the lower part of the coating wall is arranged inclined inwards under the coating opening part.
  • the collar edge is designed as one half of a labyrinth seal to accommodate the coating pan opening edge formed as the other half of the labyrinth seal.
  • the sealing gap of this labyrinth seal in the collar is at least partially covered by an elastic strip and with air acted upon.
  • a strip made of rubber or elastic plastic is particularly suitable as the elastic strip. Because air is applied to the sealing gap and at least partially covered by the elastic strip when the collar is used, the air is preferably driven out of the sealing gap of the labyrinth seal to the outlet of the labyrinth seal in the black technical area. This prevents dust particles or germs from moving from the black technology area to the gray production area.
  • a collecting container can be arranged on the lower collar edge on a collecting line. The coarse particles thus fall into this collecting container.
  • FIG. 1 shows a cross section through a coating pan and the coating wall according to the invention.
  • the cross section passes through the rotation axis of the coating pan and runs vertically between the ceiling 3 and the floor 15 of the room.
  • the black zone is identified by the reference number 1 enclosed in a circle; the gray zone is identified by the reference number 2 enclosed in a circle.
  • the drive unit 15 with the coating pan 1o on the axis 11 and the probe 5 are arranged.
  • the probe 5 is on the upper part 4 of the Coating wall arranged in one piece with a holder 6.
  • the upper part 4 of the coating wall runs vertically between the ceiling 3 and the floor 15, as does the probe 5 located on the back in the black zone 1.
  • the probe 5 extends through the coating pan opening 12 into the coating pan 1o.
  • the coating opening part 11 of the coating wall is arranged in front of the coating pan opening 12 so that it is inclined accordingly. However, the inclination of the coating opening part 11 is steeper than that of the coating pan opening 12, so that the probe 5 remains in the area of the upper coating pan opening edge 9 sufficient space.
  • the interior of the coating pan 1o can be charged with coating materials and compressed air with the probe 5.
  • the vertical central part 12 is arranged on the coating opening part 11 in the region of the lower coating pan opening edge 9 '. Subsequently, the lower part 13 is arranged downwards, which is inclined inwards under the coating opening part 11. Finally, the foot part 16, which closes the coating wall to the floor 15, is arranged under the lower part 13.
  • the opening in the coating opening part 11 can be at least as large as the coating pan opening 12.
  • a closure plate usually consists of hard-elastic, transparent plastic.
  • the space corresponding to the cross section of the coating pan opening 12 or the coating opening part 11 is separated from the black zone 1 by a collar 8 over the entire circumference of the coating pan opening 12.
  • the collar 8 is thus a cylindrical wall which is wedge-shaped in height, namely the narrower part of the wedge lies in the region of the lower collar edge 7 'or the lower coating pan opening edge 9'. the wider or higher area of this wedge-shaped collar 8 then lies in the area of the upper collar edge 7 or the upper coating pan opening edge 9.
  • the probe 5 is guided through the collar 8 adjacent to the upper collar edge 7.
  • the implementation can be rigid, so that there is no play in the probe 5 in the collar 8.
  • the collar 8 is connected in one piece to the coating wall according to the invention, in particular the coating opening part 11.
  • the above-described spatial area between the coating opening part 11 and the coating pan opening 12 is correctly assigned to the gray zone 2 and separated from the black zone 1.
  • the seal between the coating pan opening edge and the collar edge can be designed as a labyrinth seal. This will be described in more detail with reference to FIG. 3.
  • FIG. 2 the section of a plate element of the coating wall according to the invention is shown in cross section.
  • the plate element is designed as a multilayer plate.
  • black zone 1 a layer of filling foam 29.
  • This filling foam is a known sound-absorbing foam.
  • the filling foam 29 is thus enclosed between the steel sheet 30 and the galvanized sheet 28.
  • a layer of cellular rubber 34 is arranged on the galvanized sheet 28 towards the black zone 1.
  • the connection of two individual elements or plate elements of the coating wall can also be seen in FIG. 2.
  • the galvanized sheet 28 is bent away from the black zone 1 to the gray zone 2.
  • the two edges thus formed are encompassed by a holding element 31 on the side of the filling foam 29.
  • the cellular rubber 34 is extended from the black zone 1 to the gray zone 2 to prevent dirt bridges.
  • the steel sheet 3o is bent from the gray zone 2 into the black zone 1 and is arranged over the bent edge of the galvanized sheet 28.
  • the two individual elements are spaced apart by a counter element 33. The gap between the two individual elements is covered toward the gray zone 2 by the cap 32 with cellular rubber 34.
  • FIG. 3 shows a detailed view of the labyrinth seal between the collar 8 and the edge of the coating pan.
  • the guide wall 20 is molded onto the collar 8 perpendicularly outward from the collar opening to the collar.
  • a fan 18 is arranged on the guide wall 2o via the air duct 19. The fan 18 acts on the sealing gap 35 with air.
  • the baffle wall 21 is again formed perpendicular to the guide wall 2o parallel to the wall of the collar 8. This baffle 21 is then molded parallel to the guide wall 2o inwards to open the collar 8 as a counter wall 24; then the counter wall 24 is again molded parallel to the baffle wall 21 to the outside to open the collar 8 in the rear wall 27.
  • the sealing gap 35 is at least partially covered by an elastic strip 17.
  • the bar 17 must be elastic, since the coating pan 1o always evades its rest position due to different loads and therefore sometimes requires considerable play.
  • the strip 17 prevents the air from escaping from the sealing gap 35 towards the coating pan opening or into the collar 8 and thus into the gray zone. Instead, the air must escape to black zone 1.
  • the coating pan opening edge in the figure the lower coating pan opening edge 9 ', is molded from the coating pan 1o outwards to the collar 8.
  • the outer wall 25, which in the rest position is aligned parallel to the guide wall 20 on the collar 8, is then formed perpendicularly from the lower edge of the coating pan opening 9 ′ or from the opening of the coating pan.
  • the outer wall 25 is then spaced apart from the baffle wall 21 and molded parallel to the inner wall 26.
  • the path of the air emerging from the fan 18 in the sealing gap 35 is indicated by arrows.
  • the collecting container 23 is arranged on the collecting line 22. Coarse particles which are not entrained by the air flow into the black zone can fall into this collecting container 23.
  • the bar 17 is flush with the coating pan edge.
  • a ring line for the air supply can be arranged over the circumference of the labyrinth seal, from which the air is blown into the sealing gap via many individual air ducts 19 distributed over the entire circumference.
