Definitions

  • the invention relates to a heating section for a corrugated cardboard system with the features of the preamble of claim 1.
  • Such a heating section for a corrugated cardboard system is known from DE-OS 34 10 829.
  • the disadvantage here is that the air is pressed through the conveyor belt and a kind of air lubrication occurs between the conveyor belt and the corrugated cardboard to be conveyed. This reduces the conveying effect of the conveyor belt.
  • the air pressed into the conveyor belt prevents the absorption of water vapor, which is emitted by the heated corrugated cardboard.
  • the invention has for its object to improve a heating section for a corrugated cardboard system so that the conveying effect of the conveyor belt and the absorption capacity for water vapor emerging from the corrugated cardboard is maintained.
  • a wear-free seal between the underside of the pressure hood and the top of the conveyor belt should be achieved with little or no leakage.
  • this separating means is formed by an air-impermeable endless belt moved with the conveyor belt or the corrugated cardboard, no relative movement occurs between the conveyor belt and the separating means. There is a reduction in wear.
  • the lower edges of the pressure hood are bent inwards, a good and low-wear sealing against the separating agent is achieved.
  • the heating section 1 of a corrugated cardboard system has a plurality of heating plates 2, one behind the other. Its flat surface forms a heating surface 3 for the conveyed in the direction of arrow I, e.g. single corrugated cardboard 4.
  • the heating plates 2 can extend in the transverse direction to the corrugated cardboard 4 over the maximum width. However, they can also be divided and controlled to different temperatures in the transverse direction.
  • a one-sided corrugated cardboard 5 coming from a single-sided corrugated cardboard machine is fed to the heating section 1.
  • the crests of the corrugations of the one-sided corrugated cardboard 5 are provided with glue.
  • a smooth cover sheet 6 is fed to the underside. By applying pressure, the cover sheet 6 is glued to the one-sided corrugated cardboard 5 and dried by the heating section 1.
  • an endless conveyor belt 8 which runs over deflection or drive rollers 9.
  • the lower run 10 runs in a plane parallel to the heating surface 3 and at such a distance that it bears against the upper cover sheet 11 and takes the corrugated cardboard 7 with it through a corresponding friction effect.
  • a pressure hood 12 is provided to increase the friction effect and the heat transfer from the heating surface 3 to the corrugated cardboard 4.
  • This pressure hood 12 has a housing 13 which, as can be seen in FIG. 2, is rectangular in cross section.
  • the top 14 is flat. It runs parallel to the heating surface 3.
  • the adjoining side surfaces 15 have edges 16 and 17 which are bent inwards.
  • the front and back also have inwardly curved edges, not shown.
  • the housing 13 is arranged fixed in space, not shown. It can be raised and lowered for additional and setting purposes, optionally controlled.
  • the ends of the housing 13 can have semicircular surfaces 18, 19. These surfaces can also be formed by tubes 20, 21, with which the side surfaces 15 are firmly connected.
  • rollers can also be provided, which are freely rotatably mounted or driven.
  • An endless belt 25 runs over the surfaces 18, 19 and the top 14 of the housing 13.
  • This can consist of air-impermeable material. It is flexible and preferably elastic. For example, a thin plastic or metal band can be used for this band.
  • the lower strand 26 of the circulating belt 25 is pressed with its underside against the upper side of the lower strand 26 of the conveyor belt 8 by the excess pressure prevailing in the interior 27 of the housing 13, which is generated, for example, by a pump (not shown).
  • the inwardly bent edges 16, 17 seal against the top of the endless belt 25.
  • the distance between the edges 16, 17 is smaller than the width of the endless belt 25.
  • the width of this endless belt 25 is equal to or smaller than the width of the conveyor belt 8, which extends in one piece over the maximum width of the heating surface 3. It consists of an air- and vapor-permeable material, so that the vapors produced by the heating through the heating surface 3, which are emitted by the corrugated cardboard 4 upwards, can be absorbed by this conveyor belt or can escape through it.
  • the lower strand 26 of the endless belt 25 ensures that air can escape from the housing 13 of the pressure hood 12 only as a leak via the sealing connection with the inwardly bent edges 16, 37. As far as possible, no air should flow through the endless belt 12. Air lubrication of the conveyor belt 8 is thus avoided.
  • the endless belt 25 has on its outside, that is to say at the lower run 26 towards the top of the corrugated cardboard 4, transverse ribs 25 ', preferably in a herringbone pattern. This makes it possible that the upwards emerging from the conveyor belt 8 vapors can evaporate laterally via the existing between the profiles 25 'transverse to the corrugated cardboard channels.
  • a small gap can be provided between the upper side of the lower run 26 of the endless belt 25 and the edges 16, 17 of the housing 13. This avoids the friction between the endless belt 25 and the housing 13. The leakage occurring is so low that the pressure in the interior can be easily maintained.
  • the gap size can also be used to regulate the pressure in the pressure hood. This also enables air to be exchanged in the pressure hood, thus allowing hot air to escape from it.
  • the edges 16, 17 are then pulled further inwards. These ends are perforated with holes 28, via which internal air from the interior 27 presses against the top of the endless belt 25.
  • the underside of the housing 13 can be provided with a bottom 29 as a closed surface. This has a multiplicity of holes 28.
  • pressure hoods 12 are present in the running direction of the single-wall corrugated cardboard 4 at a distance from one another.
  • a single endless belt 25 is assigned to these printing hoods 12.
