Definitions

  • the invention relates to a device for cleaning a plate cylinder and a blanket cylinder of an offset printing machine.
  • the printing plate is attached to a cylinder, the so-called plate cylinder.
  • the printing ink is applied to this plate cylinder by pressing the inking rollers.
  • the ink adhering to the plate cylinder is then transferred to another cylinder, the outer surface of which is provided with a rubber blanket.
  • the cylinder provided with the rubber blanket is the so-called rubber blanket cylinder.
  • the impression cylinder is opposite the blanket cylinder. It has the task of pressing the sheet of paper entering the printing unit to be printed on with color onto the blanket cylinder.
  • the ink is transported from the ink roller over the plate cylinder to the blanket cylinder.
  • a perfect print image requires, among other things, that during the above Ink transport optimal conditions with regard to the cleanliness of ink, plate cylinder and blanket cylinder prevail. In the case of dust, dirt or paint residues etc. on the plate cylinder and / or blanket cylinder, a perfect transfer of the printing ink from the plate cylinder to the blanket cylinder or from the blanket cylinder to the printing sheet is not guaranteed.
  • DE-OS 34 10 376 discloses a device for cleaning the plate cylinder.
  • the device has a traverse running parallel to the plate cylinder, which is also the guide rail of the actual cleaning device.
  • the cleaning device is positioned opposite the contamination via the guide rail.
  • the cleaning device is moved to the plate cylinder up to the plate surface and the contamination present at this point is removed by the cleaning device.
  • a device for removing dirt particles is known from the unpublished EP 0 287 822 A1. Wipers can be moved to the pressure plate by means of pneumatic cylinders. Since dirt particles can adhere to both the printing plate and the rubber blanket, it is necessary to have a cleaning device which can also clean the rubber blanket in addition to the printing plate.
  • the known prior art does not yet offer a solution to this.
  • the object of the present invention is to offer a device which ensures a quick and safe removal of impurities on the plate cylinder and the blanket cylinder by means of remote control during the printing operation.
  • the advantage of the subject of the invention is to be seen in the fact that cleaning can be carried out by means of remote control during printing operation, and cleaning can take place simultaneously at several points along the plate and blanket cylinder.
  • the embodiment shown in Figure 1 has a plate cylinder 1, a blanket cylinder 2, a rotating magnet 3 and a cleaning element 4.
  • a rotary magnet 3, with which the cleaning element 4 is in a fixed connection, is arranged behind and at the level of the pressure gap 7.
  • the cleaning element 4 is provided with two ink squeegees 5, 6, one ink squeegee 5 being directed toward the blanket cylinder 2 and the ink squeegee 6 toward the plate cylinder 1.
  • FIG. 3 shows the plate cylinder 1 (or blanket cylinder 2).
  • the rotary magnet 3 is firmly connected to the cleaning element 4, so that the cleaning element 4 can follow the movements of the rotary magnet 3.
  • the rotary magnet receives its instruction regarding the desired operating position via the control lines 10, which are connected to a control or microcomputer system, not shown.
  • the keys 8, 9 shown in Figure 2b are arranged on a control panel and connected to a microcomputer system, not shown.
  • the button 9 is pressed.
  • the rotary magnet 3 is excited to rotate by the microcomputer system and the control lines 10.
  • the cleaning element 4 shown in FIG. 1 moves in the direction of the plate cylinder 1 due to the rotating magnetic movement.
  • the side of the cleaning element 4 designed as a doctor blade 6 comes into contact with the plate surface. This will scrape off the contaminants on the surface.
  • the duration of the doctoring can be determined by providing a fixed time, or by designing the control so that the doctoring is carried out as long as the operator holds the activation button 8 or 9 depressed.
  • the rotary magnet 3 returns to its rest position, whereby the contact of the ink doctor 6 with the surface of the plate cylinder 1 is canceled.
  • An embodiment is also conceivable in which the cleaning time can be individually selected or used by means of a light pen.
  • the cleaning process takes place in an analogous order.
  • the button 8 is actuated, whereby the rotary magnet 3 is excited for a movement directed towards the blanket cylinder 2.
  • the cleaning element 4 comes into contact with the blanket cylinder 2 with its side designed as a squeegee 5, as a result of which the contamination is scraped off.
  • the above description relates to a single cleaning element 4.
  • the embodiment according to the invention provides a plurality of such cleaning elements 4, which are arranged next to one another.
  • the number of such cleaning elements 4 can be determined as required. The greater the number of such cleaning elements, the smaller the effective range of the individual cleaning element 4, based on the length of the cylinder.
  • buttons with double functions or 64 buttons with single functions are also provided (Fig. 2b). For example, are found on the plate cylinder 1 in the areas of the cleaning zones 3 ', 5', 8 ', 11', 32 ', so the buttons 8, 9 assigned to the cleaning zones are actuated and simultaneous cleaning is carried out there.
  • cleaning can be carried out on the blanket cylinder 2 with the button 8.
  • Activation of the cleaning elements by means of the button 8 and the button 9 can also take place via other input devices; e.g. via a light pen 11, as provided in the CPC system from Heidelberger Druckmaschinen AG, Heidelberg.
  • the light pen 11 is connected to a color zone display 12 via a control panel (FIG. 2a).
  • the light pen 11 When contamination occurs, for example in the area of the cleaning zones 3 ', 5', 8 ', the light pen 11 is guided to the color zone display 12 and the color zones 3', 5 ', 8' are addressed.
  • the system is designed in such a way that it is in cleaning mode during cleaning, which means that no ink zone adjustment takes place. Rather, the cleaning elements are activated during the cleaning mode.
  • the effective range of the cleaning element corresponds to that of the color zone in the above example.
  • a motor e.g. Gear motor to use.
  • buttons provided for zonal color control to also be used for activating the cleaning elements.
