Definitions

  • Printing unit cylinder with a device for reducing the torsional and bending vibrations excited by the channel rollover.
  • the invention relates to a printing unit cylinder with a device for reducing the torsional and bending vibrations excited by the channel rollover with at least one damping element arranged in the printing unit cylinder, which is excited by a web attached to the inside of the jacket of the printing unit cylinder by bumps when the cylinder channels roll over.
  • a printing unit cylinder is known in which webs are attached in order to reduce the bending vibrations when the channel is rolled over, on the inside of the jacket of the printing unit cylinder, which pass through the printing unit cylinder approximately diametrically. Via these webs, the vibrations occurring when the cylinder channels are rolled over are fed to an absorber rod which is parallel to the cylinder channel and is surrounded by a damping mass. To suppress torsional vibrations, propeller-like wings are attached to the ends of the absorber rod. In this known printing cylinder, vibrations are absorbed.
  • Damping systems are also known from GB-A-494 762, in which shocks act directly on the damping means. This results in a specific course of the deflection of the damping means in comparison to the movement of a damping mass. This also leads to unrest in the system. No combination is possible with other damping systems.
  • the object of the invention is to develop a printing unit cylinder of the foregoing type such that, in addition to the destruction or damping of vibrations by absorption to suppress the fundamental frequency for bending and torsional vibrations, the "elastic shock" which occurs when the cylinder channels roll over is fed to the damping means becomes.
  • Fig. 1 shows in longitudinal section a printing group cylinder with a channel, not shown, extending in the axial direction, in which means for attaching blankets or printing plates are positioned in the usual manner.
  • the printing unit cylinder shown in Fig. 1 comprises a cylinder jacket 1 and cylinder pin 2, 3, via which the printing unit cylinder shown can be stored in side walls.
  • damping elements 7 to 10 are supplied to damping elements 7 to 10, preferably via arms 5 and 6, which are connected to the web 4 in an approximately cross shape.
  • the damping elements preferably consist of torsion and bending springs.
  • 4 damping elements 7, 8 and 9, 10 are arranged symmetrically on both sides of the transfer web. These are each L-shaped. On one side, one leg is connected to the end of one of the arms 5, 6, while one end of the other leg ends just below the cylinder jacket 1.
  • a joint 11 is formed between the respective damping elements 7 to 10, whereby the elastic shock occurring during the channel rollover can advantageously be passed to the damping elements in the form of torsion and bending springs 7 to 10 via these joints 11, in particular the first To dampen vibration (fundamental frequency) for bending and torsional vibrations.
  • the damping elements 7 to 10 are embedded in elastic material 12.
  • the printing unit cylinder shown in FIG. 1 thus offers the possibility of conveying torsional and bending vibrations that occur during channel rollover to the damping elements 7 to 10 via webs that are fixedly connected to the cylinder jacket 1, so that these are absorbed and also to the damping elements 7 to 10 transmitted and damped over the joints 11 occurring in the channel rollover elastic shocks.
  • Fig. 2 shows a longitudinal section through another printing unit cylinder, in which the damping elements and transmission webs are modified.
  • the printing unit shown in Fig. 2 cylinder includes a cylinder jacket 13 and is supported by journals 14 and 15.
  • the joint 11 is formed here by a web 16 arranged in the middle of the cylinder, which ends with both ends just below the cylinder jacket 13.
  • Transfer arms 17 and 18, via which the shocks are fed to the damping elements 19 to 22, are arranged in an approximately cross shape on the web 16.
  • the arms 17, 18 are encompassed by the damping elements 19 to 22, which may have a tubular shape, for example.
  • one leg of the L-shaped damping elements 19 to 22 is connected directly to the cylinder jacket 13. In this way, on the one hand it is achieved that the entire arrangement is positioned in the desired position inside the printing unit cylinder and, on the other hand, the vibrations occurring when the channel is overrun are transmitted via the legs of the damping elements 19 to 22 which are fastened to the cylinder jacket 13.
  • damping elements 24 and 25 are preferably positioned in the middle, on which at least one shock transmission disk 26 is arranged.
  • the shock transmission disk 26 has recesses 27, 28 into which the transmission pieces 29 connected to the cylinder jacket 23 protrude.
  • joints 11 are formed which can absorb or transmit both radial impacts and rotary impacts.
  • To the side of the transmission piece 29 are the joints 11 for the transmission of rotary shocks, while the radial shock transmission takes place in the direction of the pressure cylinder center.
  • the damping elements 25 are also fed with vibrations via webs, which are taken directly from the cylinder jacket.
  • FIG. 4 shows a further variant of the printing unit cylinder according to the invention, consisting of a cylinder jacket 30 and axle journals 31, 32.
  • a transmission web 33 Connected to the cylinder jacket 30 is a transmission web 33, to each of which transmission arms 34, 35 are fastened on one side, via which the damping elements 36 to 39 30 vibrations are fed directly from the cylinder jacket.
  • butt joints 11 are formed by shock absorbing pieces 40 to 43, which are connected to the damping elements 36 to 39, via which elastic shocks, advantageously supplied via the same path 33, are transmitted during the channel rollover and are fed into the system from the damping elements 36 to 39.
  • the excitation is preferably initiated in the center of the cylinder, but the joints are preferably arranged in the vicinity of the center, however, as desired.
  • the invention thus offers the possibility of using or using absorbers in combination with means for absorbing and damping the "elastic shock" of bending and torsional vibrations, the absorbers preferably being arranged in the middle of the cylinder, where the greatest deflection takes place, and also the "elastic shock” in the middle of the cylinder can be fed to the damping system.
  • the damping elements in all embodiments can be embedded in damping materials, for example foamed elastic materials.
