Definitions

  • the invention relates to a sheet guiding device in the delivery area of a sheet-fed rotary printing machine, via which printed paper sheets are brought from a last printing unit with the aid of gripper bridges running around endless chain tracks to one or more brake rollers arranged downstream of the sheet guiding device, braked by the latter and subsequently placed on a stack, and the Sheet guiding device in a rising area consists of guide plates arranged underneath the chain conveyor and between these and the brake roller provided in a horizontal area, arranged tangentially to the guide plates against the conveying direction and distributed over the width of the sheet guiding device equidistant guide bow blowers.
  • Such a sheet guiding device is known from DE-OS 31 13 750 A1.
  • the stall is dependent on the flow velocity of the paper, as well as paper properties such. B. depending on weight and surface roughness. With light and rough sheets of paper, the flow can be stalled even at low flow velocities.
  • the object of the invention is to design a sheet guiding device in the delivery area of a sheet-fed rotary printing machine in accordance with the preamble so that the paper sheets can be braked safely by brake rollers and a uniform sheet guidance can be achieved with the different claims for perfecting.
  • this object is achieved in that the guide plate as a perforated plate is arranged upstream of the guide bracket blowers in the conveying direction in an upper region of the guide plates is formed and that fans are provided below the perforated plate distributed over the width of the perforated plate.
  • the air cushion reinforced by the blown air in the area in front of the guide bar blowers can be partially extracted through the perforated plate by the known fans and thus reduced over the perforated plate.
  • the paper sheet is drawn evenly and quietly over the air cushion without touching the baffle.
  • the printed sheet underside does not smear.
  • the air cushion can be sucked off as completely as possible with the help of the fans, so that the sheet is guided safely from the guide plate to just before the guide bracket blower.
  • the paper sheet can be brought up and braked by the following brake roller and braked by this, both in the case of face and back printing.
  • the sheet guide can be easily adapted to the different ideal conveying conditions of perfecting and perfecting.
  • the risk of fluttering and the resulting smearing effects due to the natural air cushion that builds up at high printing speeds can be further reduced by designing the guide plate as a perforated plate in the middle and lower area of the sheet transport. Part of the air cushion that builds up escapes through the openings in the perforated plate.
  • FIG. 1 and 4 show the delivery area of a sheet offset rotary printing press, in the paper sheet 18 of Feed chains 2 attached to chains 1 from a printing cylinder 28 of the last printing unit mounted in the machine side frames via a sheet guide device 29 and brake rollers 14 to the delivery stack 8.
  • the chains 1 run over the chain deflection wheels 4 and 5.
  • the brake rollers 14 brake the sheet 18 to such an extent that it only comes into contact with the stacking stops 19 at a low speed.
  • the sheet guide device 29 consists of a sheet guide plate 9 fastened between the side frames 3 and a plurality of guide bracket blowers 12 distributed over the width of the guide plate 9.
  • the guide bracket blowers 12 each consist of a guide bracket 11 which is guided around the end of the guide plate from bottom to top and is located above the Baffle plate 9 nestles against this, and a blowing nozzle 13 oriented tangentially to the baffle plate 9 in the counter-conveying direction.
  • the guide bar blowers 12 are each connected to a hose 15 at their end opposite the blowing nozzles 13.
  • the hoses 15 open into a distributor pipe 16, to which a hose 17 is in turn connected.
  • the hose 17 is in turn connected to a compressor, not shown.
  • the guide bracket blowers 12 are laterally displaceably fastened to a cross member 20 which is mounted transversely to the conveying direction between the side parts.
  • the baffle 9 is provided with holes 21 in the upper baffle area 10 in front of the blowing nozzles 13 of the guide bracket blowers 12. Below the perforated plate 30 designed in this way, a fan row 22 is fastened transversely to the conveying direction, consisting of a plurality of uniformly spaced fans 23 distributed over the width of the perforated plate 30.
  • the sheet guide plate 9 can also be formed in the middle and lower region as a perforated plate 30 with holes 21.
  • a single suction chamber 26 is provided below the area of the baffle plate 9 which is formed as perforated plate 30 and extends downwards, the top surface of which forms the bend plate 9 which is designed as perforated plate 30.
  • the suction chamber 26 is connected to a single fan 27 via a channel 23.
  • a commercially available DIN perforated plate serves as perforated plate 30, for example, according to DIN 24041, perforated plate RV 5/7 with 46% free perforated area and hole diameters of 5 mm.
  • the fans mentioned are adjustable.
