Definitions

  • the present invention relates to a device for Setting an inking or dampening roller of a printing press with respect two adjacent fixed rollers according to the preamble of claim 1.
  • the inking and dampening unit rollers are adjustable, that is, that the contact pressure on the adjacent rollers with which the adjustable Rolls come into contact, also adaptable during production is.
  • These adjustable inking and dampening rollers are soft elastic surface. This can result in fixed rollers the contact pressure to the neighboring rollers with which it is in contact, to change.
  • the main reason for this is the changing conditions of Machine standstill, in which the contact pressure in a known manner by making an impression, for example, of the application roller on the Plate cylinder is adjustable up to full production speed. Each the higher the speed, the greater the contact pressure.
  • Such devices for setting inking or Dampening rollers are known.
  • DE-A-38 25 517 shows such a device.
  • two adjustment devices housed which are substantially perpendicular to each other stand and with which the bearing arrangement with respect to the machine frame adjusted in any direction of a plane within the setting range can be.

  • the device according to the invention can be constructed in a simple and space-saving manner be.
  • Another object of the present invention is to design them in such a way that in addition to adjusting the corresponding roller it is also possible to park one of the adjacent rollers, whereby the parked roller remains in contact with the other neighboring roller Roller.
  • each bearing assembly is attached to a support member which is in a bracket is held.
  • the connection between bracket and supporting part is made by a Swivel lever which is pivotally held in the holder and on which the supporting part is pivoted. This allows the support part in easier Way to follow the control curve when the support member relative to the bracket and moved along one of the axes to adjust the roller.
  • the support part must be provided on the side with support means, and that only the first axis, which is rotatably and non-displaceably held in the supporting part, in the middle Area is equipped with a thread, which in a corresponding Counter thread is screwed into the swivel lever so that by twisting this axis by means of a motor and a gearbox together this axis can be moved with the support part.
  • control cam By using a swivel lever, the control cam have a virtually any shape so that when they are on a part is attached, which is releasably and interchangeably attached to the support member in their shape can be adapted to the desired requirements.
  • the guide part with respect to the holder is advantageous it is attached, adjustable so that when the roller is inserted into the bearing arrangements the ratio of the contact pressure to the two neighboring ones Rollers are changeable and adaptable to the existing needs.
