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. Then the cylinder is held on one side for changing the jacket of the cylinder by a working cylinder engaging on the pin protruding from the side wall of the machine.
  • a joint 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 during operation of the cylinder.
  • the runout 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.
  • the printing unit cylinder is only fixed in the pulling direction of the working cylinder, as a result of which the jacket can only be guided through the opening in the side wall with difficulty and with the risk of damage.
  • the one-sided fixation of the printing unit cylinder suggests the storage of its journal in a self-aligning bearing.
  • the invention is based on the object, in a bearing for a printing unit cylinder of a web-fed rotary printing press with an auxiliary device for holding the cylinder on one side, which carries an exchangeable jacket which can be pushed laterally through an opening in a machine side wall, to design the auxiliary device such that it comprises the printing unit cylinder locked and not touched during printing.
  • the object is achieved in that on the journals of the cylinder mounted in the other side wall of the machine outside and / or within this side wall of the machine one slidably mounted in the frame, supporting the tenon and partially encompassing a carriage by means of an eccentric.
  • the cylinder (s) hold the cylinder reliably on all sides. This provides the prerequisites 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 on the bearing is also at Changing the cylinder jacket kept lower.
  • 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 slide is advantageously displaceable if, according to the invention, it has an elongated hole transverse to its direction of movement, into which the eccentric pin of an eccentric pin engages, or is acted upon by a spring which is supported in the frame and is non-positively supported on an eccentric pin.
  • the eccentric adjustment can advantageously be carried out if, according to the invention, a working cylinder acts on the eccentric.
  • 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. It protrudes from the machine side wall 5 and carries a gear wheel 9.
  • a slide 10 is arranged on the inside of the machine side wall 5 below the pin 3. It is guided in a straight line between four collar screws 11 to 14 screwed into the machine side wall 5 (FIG. 2).
  • the carriage 10 has a recess 15 on the upper end face.
  • the jacket 2 To change the jacket 2, it is axially removed from the cylinder 1 moved through the opening 7 of the machine side wall 6 from the printing press.
  • the slides 10 and 21 are pushed into the position shown in FIG. 1 by means of the working cylinders 20 and 25.
  • the cylinder 1 is held on one side in its position assumed in the printing operation. This position can be adjusted by varying the end position of the eccentric bolts 18 or 23. This is accomplished by changing the screwing depth of the piston rod of the working cylinder into the fork head mounted on it, in FIG. 2 into the fork head 26.
  • the slides 10 and 21 are moved from the pin 3 by reversing the working cylinders 20 and 25.
  • FIGS. 4 and 5 Another embodiment of a carriage is shown in FIGS. 4 and 5.
  • the carriage 27 has three elongated holes 28 to 30 running in its sliding direction, in which it is fastened to the machine side wall 34 with tenon screws 31 to 33.
  • the carriage 27 with spacers 35; 36 kept at a distance ( Figure 5).
  • the slide 27 is supported on an eccentric bolt 38 mounted in the machine side wall 34.
  • the latter carries a lever 39 on which a working cylinder is articulated with its fork head 40.
  • the slide 27 supports the pin 41 of a printing unit cylinder when its jacket is to be changed.
  • the eccentric pin 38 is rotated by reversing the working cylinder, and the compression spring 37 moves the carriage 27 away from the pin 41.
  • the invention has been described using two slides on either side of the machine side wall. Also part of the subject matter of the invention, the cylinder can also be supported only with a slide arranged outside or inside the machine side wall.
