Definitions

  • the invention relates to a bearing for a printing couple cylinder of a web-fed rotary printing press according to the preamble of patent claim 1.
  • Such storage of a cylinder is presented in DE-OS 27 24 653.
  • the cylinder is then held on one side for changing the jacket of the cylinder by a working cylinder engaging the pin protruding from the side wall of the machine.
  • a working cylinder engaging the pin protruding from the side wall of the machine.
  • an articulated head on which the working cylinder is articulated, is arranged on the journal and is mounted on a roller bearing.
  • a disadvantage of this device is that the working cylinder is connected to its journal even when the cylinder is in operation. Concentricity of the pin causes constant friction between the piston rod and the stuffing box of the working cylinder, which leads to failures of the working cylinder and downtimes of the printing press. Furthermore, the printing unit cylinder is only fixed in the pulling direction of the working cylinder, which means that the jacket can only be guided through the opening of the side wall with difficulty and with the risk of damage. In addition, the one-sided fixation of the printing unit cylinder suggests the storage of its journal in a self-aligning bearing.
  • EP 0 279 394 A3 shows a device which holds a printing unit cylinder in suspension in such a way that an eccentric shaft with a recess, embodying a conical roller, presses on the pin protruding from the printing unit side wall. To operate the shaft, it carries a square.
  • the object is achieved in a generic device by the objective features of the characterizing part of claim 1.
  • the cylinder is reliably held on all sides with the pivoted rollers. This creates the conditions for a gentle change of the cylinder jacket and the avoidance of edge pressure on the bearing of the cylinder.
  • the latter makes it possible to dispense with a self-aligning bearing.
  • the force is also on the Bearings kept lower when changing the cylinder jacket.
  • the auxiliary device is not in contact with the printing unit cylinder during printing operation and is therefore not subject to increased wear which causes machine downtimes.
  • the roller can advantageously be manufactured and enables a good adjustment of the printing unit cylinder if it is composed according to the invention from two tapered rollers which are arranged on both sides of the pivotable lever.
  • the lever requires only low actuation forces with the possibility of using small and inexpensive drive means which can be operated in an energy-saving manner if it can be pivoted according to the invention with its lever arm carrying the roller into an end position perpendicular to the pin.
  • the cylinder is advantageously adjustable if, according to the invention, the lever carries a threaded piece with right and left hand threads.
  • FIG. 1 shows a cylinder 1, for example a form or transfer cylinder of an offset rotary printing press, which carries an exchangeable jacket 2.
  • the pin 3; 4 of the cylinder 1 are in the machine side walls 5; 6 stored.
  • the bearing of the pin 4 is housed in a wall piece, not shown, which is removable and thus opens an opening 7 in the machine side wall 6.
  • the pin 3 is received in a bearing 8.
  • a roller 9 can be placed, which is arranged vertically above the pin 3 on a lever 10 mounted in the frame. The latter is acted upon by a working cylinder 11 pivotably mounted in the frame.
  • the roller is made of two tapered rollers 12; 13 assembled (Fig.
  • the lever 10 is mounted in a fork 15 fastened to the machine side wall 5. For its length adjustment it contains a threaded piece 16 with right and left hand threads (Fig. 2).
  • Another roller 17, which is the same as roller 9, is arranged inside the machine side wall 5 under the pin 3. It is attached to a corresponding, only angled lever 18 which is mounted in the frame and is connected to a working cylinder 19.
  • the latter is moved axially by the cylinder 1 through the opening 7 of the machine side wall 6 out of the printing press.
  • the rollers 9 and 17 by means of the working cylinders 11 and 19 in the pivoted position shown in Figure 1.
  • the cylinder 1 is held on one side in its position assumed in the printing operation.
  • This position can be adjusted by changing the position of the rollers 9 and 17 in the horizontal and vertical.
  • the roller 9 can be adjusted vertically by lengthening or shortening the lever 10 by turning the threaded part 16.
  • the horizontal adjustment can be made by changing the position of the tapered rollers 12 and 13 with respect to the lever 10 by inserting shims.
  • the working cylinder is held by two rollers on both sides of the machine side wall. Also part of the subject matter of the invention, the cylinder can only be trimmed with a roller arranged outside or inside the machine side wall.
