Definitions

  • the invention relates to a device for air cushion guidance of sheets in sheet processing machines along a guide surface according to the preamble of the first claim.
  • the underside of the sheet carries a large amount of fresh paint after turning at high area coverage of the Perfecting, which are particularly vulnerable to greasing against the baffles under the drums and in the delivery.
  • the baffles are provided with air nozzles from which expose blasting jets with the aim to form an air cushion, which supports the sheet surface.
  • Devices for the floating guidance of sheets or webs on an air cushion which is provided by areally arranged blowing nozzles with relatively high air volume flows at low blowing pressures, in rotary printing machines are known.
  • the principle of the aerodynamic paradox is preferably used, the nozzles directing jets of light at an acute angle to the underside of the arc.
  • the objectives for optimum placement of the blast nozzles in the guide surface are to create a constant air cushion over the guide surface to prevent bowing and to generate arcuate airflows within the air bag.
  • From the DE 44 06 847 A1 discloses a device for floatingly guiding sheets or webs with a guide surface divided into three longitudinal zones, each of them Nozzle is associated parallel to the sheet transport direction, a second, approximately perpendicular to the first blowing nozzle.
  • the resulting main flow direction of the central stabilization zone is directed against the sheet transport direction for the purpose of sheet stretching.
  • the main flow directions of the outer two tightening zones are directed mirror-symmetrically outwards to additionally tighten the sheets transversely to the transport direction, enclosing an angle of 135 ° with the sheet transport direction. Due to the perpendicular directions blowing directions a wave formation of the arc is avoided in the blowing direction.
  • a disadvantage of the uniformity of the supporting air cushion is the formation of longitudinal zones with different main flow directions.
  • the orientation of the nozzles in the central zone opposite to the transport direction leads to sheet flutter and also to underblowing of the sheet on upstream sheet-guiding cylinders.
  • the DE 100 64 531 A1 As the closest prior art shows an apparatus for the floating guidance of web or sheet material, with a subdivided in the conveying direction in three successive zones with different blowing directions guide surface.
  • the blowing openings of the nozzles in the first guide zone are directed essentially in the direction of conveyance, in the second guide zone the blowing direction changes into an arrangement directed to the side edges and in the third guide zone the nozzles are arranged substantially perpendicular to the conveying direction in the direction of the side edges.
  • the arrangements of the nozzles in the guide zones continuously merge.
  • the printing material inlet and outlet sides of the guide surface are designed as nozzle-free comb plates.
  • the nozzle density in the first and third guide zone is greater than in the middle second guide zone in order to compensate for the outflowing outgoing support air.
  • the disadvantage here is the blowing direction in the first guide zone against the upstream printing cylinder, whereby the sheets tend to undefined detachment of the impression cylinder surface under whip formation and greasing.
  • the DE 42 09 067 A1 are described mirror-symmetrically arranged transversely to the sheet transport direction arranged zig-zag-shaped Blasdüsengoln outwardly directed resulting air currents, in which an air deficit arises in the center of the sheet through the directed to the sheet side edges arcuate Blas Kunststoffströme.
  • the risk of smearing the freshly applied ink on the guide surface caused by the low flying height of the arc centers is compensated by additional hole nozzles in the middle zone, which blow additional support air perpendicular to the underside of the sheet.
  • the blowing nozzles are arranged so that an outgoing blown air jet blown behind in the blowing direction in each case downstream nozzle, so that in the back spaces of the nozzles no Vacuum areas arise in which the sheets are sucked to the guide surface.
  • the invention is therefore based on the object to improve the air cushion guide of bow by an optimal adjustment of the blast air flows in the air cushion to the respective Bogen Operationsser Dunisse to ensure a smooth smudge-free sheet travel.
  • the object is achieved by a device having the features of the first claim.
  • the air cushion guide according to the invention has the advantage that the arrangement, the blowing direction and the density of the introduced into the guide surface nozzles ensures the formation of a uniform air cushion and both on the required Bogenstützkraftverlauf over the guide surface as well as to be achieved in the upstream or downstream sheet guide sections or to be avoided.
  • the nozzle density is matched to the locally to be provided support force of the air cushion in dependence on the inclination of the guide surface relative to the horizontal and the resulting normal force of the bow on the supporting air cushion.
  • blowing directions in the sheet inlet and outlet areas of the guide surface is such that adverse effects of Blas Kunststoffströme be avoided on adjacent sheet guide sections or the sheet guide is supported in the adjacent sheet guide sections.
  • Essential condition for the desired homogeneity of the air cushion, ie to avoid vortex forming equalizing flows within the generated air cushion, is a continuous transition between nozzle zones with different blowing direction and / or nozzle density (quantifiable by the sum of the nozzle cross sections with respect to the guide surface). Blowing direction and nozzle density within the rows of nozzles transversely to the transport direction of the sheets are preferably constant.
  • the device for air cushion guide is particularly suitable for use in sheet-fed rotary presses after sheet turning facilities to avoid the smearing of fresh printed sheet undersides on the guide surfaces.
  • the nozzles D1, D2 are arranged within the guide surfaces mirror-symmetrically to a symmetry line 6 extending in the sheet transport direction in the guide surface center.
  • the guide surfaces ÜT1, ÜT2 with the blowing air can be acted upon nozzles D1, D2 close associated blow boxes K1, K2 from above, which are supplied by separate fan groups V1, V2 with blowing air.

  • ÜT1 ÜT2 comb-shaped recesses 5 for the gripper (Fig. 2a).
  • additional nozzles D3 are provided between the comb-shaped recesses 5, which "lift” the sheets without contact on the sheet outlet edge of the guide surface ÜT2.
  • the two guide surfaces ÜT1, ÜT2 border approximately midway below the transfer drum axis almost gap-free to each other.
  • the guide surfaces ÜT1, ÜT2 or the associated blow boxes K1, K2 can be coupled by known means.
  • the bubble guide is shown within a sheet delivery.
  • the sheets are transferred from the printing or lacquer printing cylinder 1 of the last printing or coating unit to a delivery chain 8, the sheets are detected by gripper carriage of the delivery chain 8 and transported to the delivery stack 11.
  • Below the delivery drum 7, which forms the lower deflection point of the delivery chain 8 two adjoining guide surface AT1, AT2 are arranged with Blas Kunststoffdüsen D1, D2 analogous to the transfer drum 2, which lead the sheets floating.
  • convexly curved lower and upper guide surfaces AU AO guide the bows.
  • the upper guide surface AO is followed by a variable-length horizontal guide surface V, which bridges the arc format-dependent gap to a functioning as a sheet brake suction roller 10.
  • the suction roll 10 is adjusted together with the variable-length guide surface V on the sheet trailing edges, so that a different coverage ratio of the variable guide surface V results with the upper guide surface AO.
  • the bows are guided on the guide surfaces AU, AO, V by means of air cushion.
  • the blast air supply is analogous to the air cushion guide ÜT1, ÜT2 floating on blow boxes and fan groups.
  • Air bubble guides with parallel blowing direction of the nozzles can flutter along the rectilinearly propagating blast jets and the resulting main flow of the bow.
  • opposite guide surface areas in the immediate vicinity of the nozzles and in the spaces between the nozzles by the ejector effect of the blowing jets created negative pressure areas that affect the constancy of the air cushion and in which there is a risk of suction of the arc to the guide surface.
  • deposited in these back spaces preferably color particles and gradually build up color deposits that pollute the bow.
  • the blowing nozzles D1, D2 are preferably arranged so that an outgoing blown air jet is directed to a free space between each downstream nozzle in the blowing direction, so that no negative pressure areas can arise in the spaces between the blowing nozzles D1, D2 (FIG. 2a).
  • each blow jet is interrupted by a second air jet blowing approximately at right angles to the first.
  • the blast jet of each nozzle spreads only in a straight line over a short distance and retains its high flow velocity only at this short distance, so that no wave formation can occur.
  • successive nozzles D1, D2 are arranged with offset by 90 ° blowing direction, as from the DE 42 09 067 A1 or DE 44 06 848 A1 known.
  • the superimposition of the jet jets of the nozzle pair D1, D2 leads to a resulting main flow at an angle of 45 ° to the blowing directions of the associated nozzles D1 and D2, which - when directed to free sheet sides - exerts a bow-firming effect.
  • the resulting main flow direction includes a main flow angle (HSW) with the line of symmetry 6.
  • HSW main flow angle
  • the normal force and thus the pressure of the sheet on the supporting air cushion depends on the inclination of the sheet with respect to the horizontal and the basis weight of the sheet, it depends on blowing pressure and air flow of the nozzles D1, D2, D3, D4 to be applied locally Adjust support forces.
  • the applied support force is less than in the predominantly horizontal track sections under the transfer drums 2, delivery drums 7 or in the delivery chain 8, where the gravity components must be absorbed in full by the air cushion.
  • the nozzle density is selected to be greater in horizontal guide surface areas than in rising or falling guide surface areas.
  • the nozzle density steadily increases from the predominantly vertical web region to the predominantly horizontal web region below the axis of the transfer drum 2.
  • the nozzle density can be linked to the air cushion with the longitudinal coordinate x of the guide surfaces ÜT1, ÜT2 in the sheet transport direction via a linear or advantageously angular function corresponding to the course of the normal force of the sheet on the air cushion (FIGS. 2a and 2b).
  • the nozzle density in the guide surfaces AT1, AT2 under the delivery drum 7 (FIG. 4) also increases steadily in the sheet transport direction as far as the lower horizontal area and in the direction of the rising guide surfaces AU, AO with a lower support force requirement.
  • the nozzle density is high again, since the sheets rest here again with their entire weight on the supporting air cushion.
  • the blowing pressure for the entire guide surface can be changed within the adjustment range of the associated blown air source (for example speed range of fans).
  • the blow pressure locally only in certain guide surface areas, for example to increase the supporting force of the air cushion in a horizontal guide surface portion.
  • one or more blow boxes may be arranged under a guide surface transversely or longitudinally to the sheet transport direction, each with its own blown air supply under the guide surface, which supply different nozzle zones with blown air.
  • the guide surface may be composed of a plurality of connectable partial surfaces, wherein each partial surface or a plurality of partial surfaces is associated with a respective blow box.
  • a combination of a plurality of coupling blow boxes K1, K2, each with its own partial guide surface ÜT1, ÜT2 to a guide surface is possible.
  • Essential for a combination of several partial surfaces is the avoidance of discontinuities in the nozzle density at the associated edge zones of the partial surfaces ÜT1, ÜT2, AT1, AT2.
  • a separate Blas Kunststoffbeetzschlagung individual guide surface areas can also be used to advantage for switching on and off the support air in those guide surface areas in which an air cushion is needed only for certain sheet sizes, sheet thicknesses or high paint orders.
  • the use of multiple coupled blow boxes instead of a single blow box also allows the use of smaller fans for Blas Kunststoffmakers, so that the installation flexibility can be improved.
  • nozzles D1, D2 are arranged mirror-symmetrically to a line of symmetry 6 running in the direction of sheet transport in the center of the guide surface, an air deficit in the region of the symmetry line 6 can be caused by the support air flowing symmetrically in the direction of the sheet side edges, resulting in a reduced support height Bow in this zone expresses.
