Definitions

  • the invention relates to a sheet guiding cylinder of a printing press ne, which is mounted in the machine nensei tenste l len and for which there is a drive connection to the press drive, with a through surface provided with through-holes, with means for supplying blown air into the sheet guide cylinder and with means for deflecting the Blown air in cylindrical shape inside the sheet guide cylinder.
  • the invention is based on the problem of achieving a more secure guidance of printed sheets with simple means.
  • the problem is achieved by training the sheet guiding cylinder in accordance with the features of claim 1.
  • the Radia Iventi Lator which is rotatably mounted in relation to the sheet guide cylinder and driven independently of it, enables safe sheet guidance over the entire working area of the printing press. Both when the machine is stopped and when the speed is very high, the speed of the radiator can be lively due to the speed independent of the sheet guide cylinder
  • the air cushion required for safe sheet guidance can be set individually. Even with an abrupt machine stop, sticking of the printed paper sheet side to the sheet guide cylinder can be avoided. Secure sheet guidance is guaranteed over the entire area of the sheet guide of a sheet guide cylinder.
  • the passage openings in the side walls of the sheet guiding cylinder allow sufficient air supply without additional external effort.
  • the high maintenance and assembly effort of external air supply means is eliminated.
  • the safe sheet guidance is done with simple means. No additional provision of space for complex air supply means is required.
  • the control effort for controlling the Radi a Lventi Lator is low compared to the known regulations for external air supply.
  • Reducing the smear effects enables a reduction in the paper waste, an improvement in the quality of the printed sheets due to the elimination of the ink transfers to the following sheets and the reduction in cleaning requirements for the sheet guide cylinders.
  • the embodiment of the invention according to the feature of claim 2 enables an additional improvement in the air supply to the Radi a Iventi Lator. This improves the ability of the desired air cushion and the safe sheet guidance. Due to the better efficiency of the Radi a Lventi Lator, it can be used in a more energy-saving manner, the power of the drive means is smaller, and the cost and space required for the drive L can be reduced.
  • Di e Ausbi invention ldung according to the feature of claim 3 provides an additional improvement in the air supply.
  • the he education according to the features of claim 4 enables a safe, uniform air supply over the entire width of the sheet guiding cylinder.
  • the inventive design according to the feature of claim 5 enables a safe, uniform supply of blown air over the entire width of the sheet guide cylinder with particularly simple, preferred means.
  • the device according to the features of claim 6 enables a particularly simple, preferred drive connection for the Radia Lventi Lator.
  • the drive means can be arranged entirely outside the machine side wall and thus do not block the space between the machine side walls, which is already narrow.
  • the drive means are easily accessible.
  • the control for the drive lever L can be made particularly simple.
  • the configuration according to the invention according to the feature of claim 8 enables an additional tightening of the conveyed sheets by the blowing air directed against the conveying direction of the paper sheets. This proves to be particularly advantageous when the machine is stopped at short notice.
  • the direction of rotation of the radial fan is made changeable according to the feature of claim 9. This allows an optimal adjustment of the desired blas air supply to the print job pro. In particular, the change from very thin
  • Sheets of paper on very thick sheets of paper and vice versa can be used this embodiment can be carried out particularly safely.
  • FIG. 1 side view of a chain made of Legers with from outside the Maschi nenactedgest l le arranged motor for the Radi a Lventi Lator
  • FIG. 2 top view of the exemplary embodiment L according to FIG. 1
  • FIG. 3 side view of a chain made of Legers with between the Be tengest l Len arranged motor
  • Sheetfed offset rotary printing aschi ne in which the printed paper sheet from the printing cylinder 9 of the last printing unit is taken from the gripper bars 10 attached to chains 3 and transported and stored there via a storage stack L 2, the gripper bars are attached to two chains 3 between the Be tengested L len 7 and 8 transported. In the area of the laying drum 11, the chains 3 are each over
  • Sprockets 5 and 6 run all around.
  • the sprocket 5 is fastened on a stub shaft 13 which is in the side wall 7 is rotatably mounted and on its extension outside the Be tengest l Ls 7 a gear 12 is attached, which is connected to the printing press drive, not shown.
  • the sprocket 6 is concentric to the sprocket 5 also rotatably mounted on a stub shaft 14 in the machine tenense 11 8.
  • the stub shaft 14 is designed as a hollow shaft.
  • a shaft 16 is rotatably mounted concentrically with the shaft stumps 13 and 14 and is extended towards the outside by the shaft shaft stump 14. On the extension outside the
  • Maschi nensei tengest l Ls 8 a motor 15 is mounted, which is supported in a known manner against the Maschi nensei tengest l L 8.
  • the shaft 16 extends transversely to the Bogen everydayri direction and is rotatably supported with its other shaft journal in the shaft end 13.
  • a circular holding flange 17 is fastened on the shaft 16, in its outer circumferential area ch on both sides to the machine side parts L len 7 and 8 distributed over the circumference of the holding flange 17 at equal intervals distributed guide vane plates 18 or 19 for radial venti lation are attached.
  • the Lei shovel plates 18 and 19 extend outwards over the entire conveying width and are provided in their outer region with ring plates 25 and 26 aligned concentrically to the axis 16. Between the sprockets 5 and 6 circular flanges 20 and 21 are also attached to the shaft ends 13 and 14. Towards the middle of the machine, concentric to the axis 16, aligned inlet nozzles 24 are attached to the flanges 20 and 21, which are located inside the guide blades 19 between the lever blades 19 and the axis 16
  • the chains 3 are driven by the printing press drive via the gear wheel 12, the shaft end 13, the flange 20, the cross members 22, the flange 21 and the chain wheels 5 and 6. Regardless of the Lei Tschaufein 18 and 19 with the help of the motor 15 via the shaft 16 and the flange 17 are driven.
