Definitions

  • the invention relates to a device for cleaning a cylinder in a Printing machine according to the preamble of claim 1. Further relates to the invention also a printing press with such a device.
  • Such devices allow self-cleaning of the cleaner in the Housing, which shortens the cleaning time for cleaning the cylinder. Evaporation of the cleaning agent can also occur in the pressroom and Drying out of the cleaner can be prevented.
  • the self-cleaning of the cleaner takes place with a brush roller by placing it inside the closed Housing a cleaning fluid or water is supplied, which follows scraped together with the dirt from the bristles by a squeegee becomes.
  • the cleaner can also be cleaned using blown air Soiling is blown out.
  • EP 0 659 560 B1 describes a cleaning device for cylinders from Printing machines described, the housing at least one additional Movable housing part that exposes the opening in the position and / or locked in the parking position.
  • the movable housing part must be in Guided tours.
  • the guided tours can be fixed by Jammed ink residues, paper dust or the like jam. This is a problem especially in the case of very precisely manufactured guides, which are simultaneously a should have a sealing function. But also separate from the guided tours Sealing measures to seal the parts mean an increased Production expense.
  • the opening and closing of the opening via elastic springs is also unsafe and can e.g. B. with an incomplete opening, to a Damage to the cylinder surface to be cleaned and the device.
  • the object of the invention is a simple one constructed and safely functioning device for cleaning a cylinder create.
  • the object is achieved by a device with the features of Claim 1 and solved by a printing press with the features of claim 10. Further features are contained in the subclaims.
  • the device for cleaning a cylinder in a printing press, with one cleaner can be switched on and off, especially a cleaning roller, which is arranged in a housing with an opening, is characterized by that the housing by moving it relative to a cover Device is designed closable, the opening through the device is brought into cover with the cover.
  • the housing by movement, in particular Rotation, the same is closable, with closing both a completely sealing closure as well as an incomplete sealing sufficient splash protection function is understood.
  • z. B the size of the Angle by which the opening from a first position towards the cylinder in a second position facing away from the cylinder is pivoted or rotated, according to the particular design and size of the opening.
  • Simply constructed devices can be used to move the housing, so that the manufacturing effort is kept low with absolutely reliable function.
  • Cover against which the opening of the housing is directed can part already contained in the machine, e.g. a machine wall, or a specially designed part.
  • the housing and its opening can rotated, pivoted or moved relative to the cover, the Opening is directed towards the cover.
  • the housing are shifted in a straight line along a tangential plane of the cylinder, wherein the opening of a cover extending in the tangential plane is covered.
  • An advantageous embodiment can include that the opening in a Position of the cleaner towards the cylinder and in a parking position in the is essentially directed away from the cylinder. In this way, an optimal one Splash protection of the cylinder and in particular one if necessary on it led substrate before the self-cleaning process of the cleaner detergent spraying in the housing during printing guaranteed.
  • a preferred embodiment includes that the opening in the parking position of the cleaner against one arranged below the housing and here as the Cover acting tub is directed.
  • a tub is a matter of course also understood a drain surface or a catch basin.
  • Such elements are often present anyway and serve to protect those under the cleaner Machine parts in front of dripping cleaning agents and for storing them and repatriation. It is particularly favorable in this embodiment that this is in the self-cleaning process of the cleaner on the inside walls of the housing any accumulated cleaning agents run off the walls into the tub can.
  • the tub and the housing can be designed so that they are coordinated be that effective splash protection in the on and off position, d. H. in the Cylinder cleaning and self-cleaning is given.
  • a stationary, e.g. B. tub attached to the machine frame, can extend over the length extend the on and off, so that in any position of the cleaner Drip protection is available.
  • the tub can be movable, the tub with the housing, e.g. B. is connected via a gearbox, so that the Trough with an on and off movement of the housing is carried.
  • the housing z. B. filled with used detergents The tub can cover better, so that the evaporation of the cleaning agent the tub is reduced.
  • the edges of the tub can be in the parking position Cleaners overlap the outer wall of the housing in the area of the opening, so that a good sealing is achieved.
  • the housing can about a to the axis of rotation of the cylinder to be cleaned parallel axis can be rotated or pivoted. Because of this flexibility The housing allows the device to be installed in a very confined space accommodate. Particularly favorable installation conditions result if that Housing rotatable about an axis of rotation of a roller-shaped cleaner is trained.
  • Another embodiment involves moving the housing Forcibly set up the housing when the cleaner is turned off closes and opens with the adjusting movement of the cleaner.
  • An advantage of this Embodiment is that in addition to an actuator for turning on and off the cleaner no further drive to close the housing, e.g. B. for whose rotation is necessary. Deviating from that in certain Applications another drive for closing the housing and z. B. a coordinated control of the two drives can be provided.
  • Suitable drives for starting and stopping the cleaner and for Closing the housing are electric motors, hydraulic cylinders or preferably pneumatic cylinders can be used.
  • the device moving the housing can forcibly use a gear Coupling the closing or opening of the housing to the connection or Parking movement, preferably in the form of a coupling gear. It is particularly favorable to design the coupling gear as a Cross slider-crank mechanism.

  • Another embodiment may include the housing and the cleaner are coaxially rotatable. This measure enables a subsequent Installation of the device in machines with an unfavorable installation space situation and contributes to the simplification of the housing structure.
  • This can be implemented cheaply Embodiment in which the first sliding block is arranged on the housing and one the axis of rotation of the pin, in particular a roller-shaped cleaner encloses.
  • a reduction in cleaning time can in many cases, e.g. B. at the Cleaning a blanket cylinder, an impression cylinder or a Sheet transfer drum in an offset printing machine, by using a Reach brush roller as the cleaner. This is driven by rotation and can be in oscillate sideways.
