Definitions

  • the invention relates to a rotary offset printing press with preferably torsionally vibration-compensated cylinders which are mounted in axles in side walls and are arranged in parallel and synchronously driven cylinders.
  • the invention is based on the object of demonstrating a rotary offset printing machine in which bending vibrations are suppressed, as can occur in particular when passing through the cylinder pits. This object is achieved according to the characterizing part of patent claim 1. Advantageous developments of the invention result from the subclaims in connection with the description and the drawings.
  • Another advantage of the invention is that due to the height adjustability of the support elements, the diameter ratios or cylinder center distances, which are decisive for the rolling processes of the counter-rotating cylinders, can be taken into account and that there is also the possibility of rotating the support elements by means of the stop bar and its adjusting screws in such a way that damaged Get places outside the contact area.
  • Another advantage is the interchangeability of the stops which can be displaced on an inclined plane of the support elements. By using bearer rings mounted on roller bearings, it is also possible to suppress the bending vibrations with different bearer ring diameters.
  • FIG. 1 shows two synchronously driven plate cylinders 1 and 2 and blanket cylinders 3 and 4, which are mounted in side walls, not shown, in the usual way.
  • Support elements 13 to 16 are shown on the axes 5 to 8 respectively assigned to the individual cylinders 1 to 4.
  • the support elements 13 to 16 are each mounted on a bearing 9 to 12.
  • some of the support elements 13 to 16, here the support elements 14, 15 and 16 have an inclined area, on each of which a stop is slidably arranged. These are the stops 17, 18 and 19 on the support elements 15, 16 and 14.
  • the stops 17 to 1 ' 9 can be moved on the inclined plane with a corresponding adjusting device.
  • an adjusting screw 49 was only shown in FIG. 1 on the support element 14, with which the stop 19 can be moved on the inclined plane, so that a height adjustment of the support element is possible.
  • the contact pressure to the adjacent support element 16 can be set and the rolling conditions of the opposing cylinders can be taken into account in this setting so that they are optimized.
  • the support elements 13 to 16 can be rotated on the axes 5 to 8.
  • Each setting segment is assigned two setscrews in the embodiment described here, e.g. B. the support element 13, the set screws 21 and 22.
  • the support elements can be rotated with the help of the set screws so that damaged areas get outside the contact area.
  • FIG. 2 A further possible embodiment of the support elements is shown in FIG. 2.
  • the support element 30 in FIG. 2 is provided with an adjustable pressure screw 29 which can be adjusted against a support element 31 arranged on an adjacent axis.
  • the support elements In order to suppress bending vibrations, the support elements must be set to a fixed height, their dimensions preferably corresponding to the pitch circle diameter of the drive gears used in each case.
  • FIG. 3 shows rubber blanket cylinders 34 and 35 mounted in parallel in side walls, not shown, with plate cylinders 32 and 33.
  • a paper web 36 to be printed is passed between the rubber blanket cylinders 34 and 35 in a known manner.
  • bearer rings 41, 42, 43 and 44 are mounted on the cylinder axes 37, 38, 39 and 40 of the cylinders 32, 34, 35 and 33 on bearings 45, 46, 47 and 48.
  • This exemplary embodiment thus shows that bearer rings, which are arranged via bearings on the cylinder axes, are advantageously used as support elements to suppress the bending vibrations.
