Definitions

  • the invention relates to a sheet guiding cylinder of a printing press, which is mounted in the machine side frames and for which there is a drive connection to the printing press drive, with a lateral surface provided with through-openings, with means for supplying blown air into the sheet guiding cylinder and with means for deflecting the blown air in the cylinder jacket direction inside of the sheet guide cylinder.
  • sheet guiding cylinders in printing machines for conveying printed paper sheets between the printing units or in the delivery area. Sheet guiding should also be carried out safely and without smearing with printed sheets, the printed side of which faces the lateral surface of the sheet guiding cylinder.
  • outer surfaces For this purpose, it is known to provide the outer surfaces with complex special coverings.
  • the sheet guide cylinders with blown air guided from the inside to the outer surface by means of blow nozzles which are directed outward and connected in a rotationally fixed manner to the sheet guide cylinder and with a complex external blown air supply.
  • the blowing air nozzles cover only a certain area of the sheet-guiding surface. In order to cover a larger area of the sheet-guiding surface, it is necessary to arrange several rows of blowing nozzles one behind the other.
  • the external blown air supply requires a high amount of sealants, air supply means and complex blown air control.
  • the invention is based on the problem of achieving a more secure guidance of printed sheets with simple means.
  • the problem is achieved by designing the sheet guiding cylinder in accordance with the features of claim 1.
  • the radial fan 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 at very high speeds, a speed control of the radial fan which is independent of the sheet guiding cylinder can result
  • the air cushion required for safe sheet guidance can be set individually. Even when the machine stops suddenly, 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 through openings in the side walls of the sheet guide cylinder allow sufficient air supply without additional external effort.
  • the high maintenance and assembly costs of external air supply means are 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 radial fan is low compared to the known regulations for external air supply.
  • the reduction of the smearing 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 the cleaning requirements for the sheet guide cylinders.
  • the embodiment according to the feature of claim 2 allows an additional improvement in the air supply to the radial fan. This improves the adjustability of the desired air cushion and the safe sheet guidance. Due to the better efficiency of the radial fan, it can be used in a more energy-saving manner, the drive means are dimensioned smaller in terms of their output, and costs and space requirements for the drive means are reduced.
  • the inventive design according to the feature of claim 3 enables an additional improvement in the air supply.
  • the inventive design 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 inventive device enables a particularly simple, preferred drive connection for the radial fan.
  • 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 means 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 in the opposite direction to 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 designed to be changeable according to the feature of claim 9. This enables an optimal adaptation of the desired blast air supply to the print job profile. In particular, the change from very thin sheets of paper to very thick sheets of paper and vice versa can be done with this embodiment can be carried out particularly safely.
  • FIG. 1 and 2 show a delivery 1 of a sheet-fed offset printing press, in which printed paper sheets are taken from the printing cylinder 9 of the last printing unit by gripper bars 10 attached to chains 3 and transported via a delivery stack 2 and deposited there.
