Definitions

  • the invention relates to a device for drying printed sheets according to the preamble of claim 1.
  • the disadvantage here is that the air flow, like a flat impingement jet flow, flows out concentrically after hitting the web. Because this does not result in a directional flow, dead spaces can arise which have a disadvantageous effect on drying. A tightening effect by the impact jet flow on the web in the direction of the side edges cannot be achieved with this either.
  • the invention has for its object to provide a device which enables uniform drying of printing ink on sheets or webs, produces a tightening effect transverse to the conveying direction and so-called dead spaces - these are spaces in which none Air movement takes place - avoids.
  • blow nozzles are created in a continuous blow box, which generate baffle jets that differ from 90 ° to the conveying direction and do not strike the sheet perpendicularly.
  • baffle jets that differ from 90 ° to the conveying direction and do not strike the sheet perpendicularly.
  • These directional impingement jets create a tightening effect on the end and the side edges of the sheet and a flow for the air to flow off towards the side edges of the sheet in order to avoid dead spaces which prevent drying.
  • the arrangement of the nozzles ensures that the blowing jets are covered and thus dried uniformly.
  • the device according to the invention is shown in the drawing and is described in more detail below.
  • a section of a device for drying (dryer) in a printing machine shown in FIG. 1 shows a guide surface 1 along which printed sheets 2 or webs are carried on an air cushion 3.
  • a blow box 4 is arranged opposite this guide surface 1 and is provided with a plurality of blow nozzles 6 which are directed onto the guide surface 1.
  • a distance a between the guide surface 1 and blow box 4 is chosen so that, for example, sufficient space, for. B. 100 mm for chain conveyors for transporting the sheet 2 is available.
  • the blow box 4 has a wall 7 facing the guide surface 1. Blow nozzles 6 are introduced into this wall 7 by means of a deep-drawing tool.
  • the blowing opening 12 is introduced into this surface 11.
  • the blow opening 12 is approximately circular (eg diameter 10 mm).
  • the depression 8 described can be designed as a pyramid, truncated pyramid, tetrahedron, spherical cap or circular truncated cone.
  • the surface 11 is part of a circular cone.
  • the blow jet 14 can additionally be directed with respect to the conveying direction F.
  • An arrangement of the blowing nozzles 6 pointing away from an axis of symmetry 16 counter to the conveying direction F causes a tightening effect and a discharge of the air to the trailing edges of the sheet 2.
  • the axis of symmetry 16 runs parallel to the conveying direction F and divides the wall 7 over the width, ie perpendicular to Delivery direction, symmetrical.
  • the blow opening 12 closes with parallels Symmetry axis 16 an angle gamma of -45 ° to 45 °.
  • the angle gamma is, for example, 0 °, while in the regions adjoining it, gamma is -45 ° and 45 °. However, even more areas with different gamma angles can be formed.
  • the blowing nozzles 6 are in the conveying direction F and perpendicular to the conveying direction F, ie across the width of the blow box 4, in the wall 7 of the blow box 4 in a division t, z. B. 50 - 100 mm, arranged.
