Definitions

  • the invention relates to a cleaning device for guide rollers of a printing unit, in particular a 9-cylinder satellite printing unit, a web-fed printing press.
  • printing units of web presses have multiple printing units, each printing unit having a transfer cylinder, a plate cylinder, an inking unit and optionally a dampening unit.
  • the form cylinder are also referred to as a plate cylinder and the transfer cylinder as a rubber cylinder.
  • printing units can have impression cylinders, wherein an impression cylinder can interact with one or more transfer cylinders of different printing units.
  • the impression cylinders are also referred to as satellite cylinders, which is why printing units with at least one impression cylinder are also referred to as satellite printing units.
  • satellite printing units which have impression cylinders
  • printing units are also known which do not have impression cylinders, wherein in printing units without impression cylinders, the transfer cylinders of two printing couples roll on each other.
  • Trained as a 9-cylinder satellite printing unit printing unit of a web press has four printing units and therefore four forme cylinder and four transfer cylinders, the transfer cylinders of all four printing units roll on a common satellite cylinder. Between the satellite cylinder and the four transfer cylinders a total of four printing locations are formed, with a printing material to be printed is promoted for printing through these pressure points.
  • a printing material to be printed is fed to a 9-cylinder satellite printing unit via a feed guide roller, a printing material printed in such a satellite printing unit is removed from the satellite printing unit starting from a fourth and thus last printing point via a discharge guide roller.
  • the printed substrate thus runs with his just printed in the printing unit print side on the Ab technologicalleitwalze, creating the risk that collects ink on the Ab technologicalleitwalze that obstructs the transport of the printing material in the Abvantleitwalze. It is therefore necessary to clean at least the Abvantleitwalze. So far, no cleaning devices for guide rollers of a printing unit are known from practice, which allow effective cleaning of the guide rollers, in particular the Abvantleitwalze.
  • the present invention is based on the problem to provide a novel cleaning device for guide rollers of a printing unit of a web printing press.
  • This problem is solved by a cleaning device according to claim 1.
  • the cleaning device according to the invention has an attached to an operating handle cleaning body which is inserted between guide rollers of a duck unit, wherein the cleaning body a wettable with cleaning liquid cleaning cloth is fastened, and wherein the cleaning body has on opposite sides to the contour of the guide rollers adapted cleaning surfaces.
  • the operating handle articulates on an upper portion of the cleaning body, the cleaning surfaces being formed on a lower portion of the cleaning body, and wherein the upper portion of the cleaning body is associated with a clamping means for securing the cleaning cloth to the cleaning body.
  • Fig. 1 shows a section of a designed as a 9-cylinder satellite printing unit printing unit 10 in the range of two upper printing units 11, 12, wherein each of the two upper printing units 11, 12 a forme cylinder 13, a transfer cylinder 14 and rollers of an inking unit 15 are shown.
  • the two transfer cylinders 14 of the printing units 11, 12 shown roll on a common satellite cylinder 16, forming a respective printing gap 17 or 18, whereby a printing material is moved through the printing gaps for printing.
  • the present invention provides a cleaning device 21 for cleaning the guide rollers of such a printing unit, in particular for the cleaning of the dirt-prone Abriolleitwalze 20, ready.
  • the cleaning device 21 has a cleaning body 23 which is fastened to an actuating handle 22 and which is in accordance with FIG Fig. 1 between the guide rollers 19, 20 of the printing unit 10 can be inserted.
  • the cleaning body 23 has on opposite sides of the contour of the guide rollers 19, 20 adapted cleaning surfaces 24, 25.
  • the cleaning surfaces 24, 25 are contoured identically, as well as the guide rollers 19, 20 of the printing unit 10 have identical contours.
  • the operating handle 22 articulates on an upper portion of the cleaning body 23, the cleaning surfaces 24 and 25 are formed on a lower portion of the cleaning body 23.
  • An axis 26 about which the cleaning body 23 is pivotally attached to the operating handle 22 extends according to Fig. 2 perpendicular to the longitudinal direction of the cleaning body 23 and to the longitudinal direction of the cleaning surfaces 24, 25th
  • a cleaning liquid wettable with cleaning liquid, not shown cleaning cloth can be fastened on the cleaning body 23, wherein for this purpose the upper portion of the cleaning body 23 associated clamping device 27 is used.
  • a cleaning cloth attached to the cleaning body 23 with the aid of the clamping device 27 wraps around the cleaning body 26 in its longitudinal direction such that the cleaning cloth covers the cleaning surfaces 24, 25 adapted to the contour of the guide rollers.
  • the cleaning device 21 For cleaning the guide rollers 19, 20 of the printing unit 10 is according to Fig. 1 the cleaning device 21 with its cleaning body 23 to which a cleaning cloth wetted with cleaning liquid is attached, from above between the guide rollers 19, 20 inserted.
  • a first cleaning surface 24 abuts against the feed guide roller 19 and a second cleaning surface 25 abuts on the discharge guide roller 20, wherein by performing a pivoting movement with the actuating handle 22, the cleaning body 23 in this position over the entire axial extent of the guide rollers 19, 20th can be moved.
  • This first cleaning step serves to dissolve impurities on the Abvantleitwalze 20.
  • the cleaning body 23 of the cleaning device 21 between the guide rollers 19, 20 is pulled out, rotated by 180 ° and then re-introduced between the two guide rollers 19, 20, so that for a second cleaning step after rotating the cleaning device 21, the first cleaning surface 24 of the cleaning body 23 abuts the Abfuelleitwalze 20 and the second cleaning surface 25 on Zu thoroughlyleitwalze 19.
  • the already dissolved impurities can be removed from the Ab technologicalleitwalze 20.
  • the cleaning body 23 is moved over the operating handle 22 along the entire axial extent of the guide rollers 19, 20 again.
  • the cleaning device 21 thus serves the manual cleaning of the guide rollers 19, 20, wherein according to Fig. 1 an operator 28, which operates the cleaning device 21, stands on a foot plate 29 above the guide rollers 19, 20. In this standing position, the operator 28 can clean the guide rollers 19, 20, in particular the dirt-prone Abriolleitwalze 20, the printing unit 10 with the aid of the cleaning device 21 effectively.
