Definitions

  • the invention relates to a device for changing a printing cylinder sleeve in a printing press with a frame that has a drive side and an operating side has and in which a cylinder core receiving the impression cylinder sleeve is mounted in such a way that the pressure cylinder sleeve extends axially to the operating side pull off.
  • the clichés are on a printing cylinder sleeve or a so-called sleeve, which is releasably attached to a pressure cylinder core is postponed.
  • the change can be made when converting the printing press of the sleeves in the machine frame, so that the pressure cylinder core in the frame can remain. All that is needed for the sleeve to be removed is all that is needed removed the bearing for the cylinder core located on the operating side become. The cylinder core is then boom-like by the one on the opposite Side bearing held.
  • the end of the printing cylinder on the operating side is often only poorly accessible, making it difficult to put a new sleeve all over the cylinder core to be pushed open and / or the sleeve to be removed by hand or with the help of a robot at the end to pull it off the cylinder core.
  • the object of the invention is therefore to provide a device which Replacing the pressure cylinder sleeve made easier.
  • This object is achieved by one on the drive side arranged on the frame, acting on the end face of the pressure cylinder sleeve Ejector and / or one arranged on the drive side of the frame Retraction claw, which can be detached into a recess on the edge of the pressure cylinder sleeve intervenes.
  • drive side refers to the side of the printing press frame designated, which is opposite to the operator side. Usually is on this page also the drive for the various cylinders of the printing press arranged. However, this is not a necessary feature of the invention.
  • the bearings for the pressure cylinder core are preferably mounted on slides, which allow the impression cylinder to be placed against the impression cylinder.
  • a particularly preferred embodiment of the invention is the pusher and / or the retraction claw in one position with respect to the machine frame arranged on or near one by the axis of the cylinder core straight and parallel to the movement path of the slide lies.
  • the cylinder core can then be used to change the printing cylinder sleeve position using the slide so that the end face of the pressure cylinder sleeve comes to a position opposite the ejector.
  • Different Diameters of the cylinder core and / or the printing cylinder sleeve can then taken into account by appropriate positioning of the slide become stationary, so that it is possible for the ejector or the retraction claw to be arranged on the machine frame.
  • Figure 1 shows a view of the operator side of a flexographic press, i.e. to the side from which operating operations such as changing a printing cylinder sleeve.
  • the printing press has a frame 10 which is formed by two side parts 12 and 14, In Figure 1 shows only the side part 12. Between the side parts 12 and 14, an impression cylinder 16 is mounted, on the circumference of which several inking units 18 are arranged. Each inking unit 18 comprises an impression cylinder 20 and an application roller 22. In the side part 12 there is a window for each inking unit 18 24 recessed by the ends of the impression cylinder 20 and the applicator roller 22 are accessible.
  • the impression cylinders 20 and the application rollers 22 are individual stored in slides 26 and 28, which are independently along guide rails 30 are movable.
  • the guide rails 30 are each below of the associated window 24 on the inside of the side part 12 or 14 appropriate.
  • On the operating side are the bearings for the printing cylinders 20 and Applicator rollers 22 are designed as folding bearings or removable bearings
  • the printing cylinder 20 and the application roller are 22 on the opposite drive side of the drive side each in the associated slide 26 and 28 mounted.
  • Figures 1 and 2a show the printing press in the state in which the printing cylinder 20 is employed on the circumference of the impression cylinder 16 and the Applicator roller 22 is employed on the circumference of the printing cylinder 20.
  • FIG 2b are the pressure cylinder 20 and the application roller 22 with the aid of the slide 26 and 28 have been returned to their parked positions.
  • the diameter of the impression cylinder 20 varies according to that for the respective one Print order prescribed print length.
  • the drives for the sledges 26 are so based on the known diameter of the impression cylinder 20 controlled that the outer peripheral edge of the impression cylinder on that of the applicator roller 22 always facing side with the ejection and retraction device 32 is aligned.
  • the bearing is in the state shown in FIG. 2b for the pressure cylinder 20 on the operating side (on the side part 12) axially from the Axis of the impression cylinder has been pulled off, so that it can then be used of the carriage 26 can be moved to the side, as shown in FIG. 2c.
  • the impression cylinder is then due to the double bearing on the opposite side held on the side part 14 in a boom-like manner.
  • the pressure cylinder 20 has a cylinder core 36 onto which a printing cylinder sleeve 38 bearing the clichés is postponed.
  • the pressure cylinder sleeve 38 with the help of the ejection and retraction device 32 shifted a little on the cylinder core 36 been so that it is easily accessible on the operator side in the window 24 lies and then easily by hand or with the help of a robot can be deducted entirely from the cylinder core 36.
  • An actuating cylinder 40 is fixedly mounted on the console 34.
  • the free end of the The piston rod of this actuating cylinder 40 forms an ejector 42 for the pressure cylinder sleeve 38.
  • a retraction claw 44 is articulated on the ejector 42 and pivotable with the aid of a smaller actuating cylinder 46. If the pusher 42 rests on the end face of the pressure cylinder sleeve 38 and the actuating cylinder 46 is extended, the retraction claw 44 engages with its hook-shaped cranked end in a hole 48 which is close to the edge in the impression cylinder sleeve 38 is formed.
  • the pressure cylinder 20 is arranged with respect to the ejector 42 that this only the pressure cylinder sleeve 38 but not the cylinder core 36. If the impression cylinder sleeve 38 is to be removed from the cylinder core, then so first the interior of the cylinder core 36 with compressed air in a known manner acted upon. The pressure acts on the inside through holes 50 in the cylinder core the pressure cylinder sleeve 38 so that it is easily expanded and can be easily moved on the cylinder core. Then with the help of the actuating cylinder 40, the ejector 42 is extended so that it is the printing cylinder sleeve pushes a distance from the cylinder core 36, as shown in Figure 4 is. The retraction claw 44 remains in the released state, so that the cylinder sleeve can be pulled off further by hand.
  • FIG. 5 schematically shows an interior view of the side part 14 of the frame 10.
  • a part of the window 24 and a section of the guide rail can be seen 30 on which the carriage 26 is guided.
  • On the sled 26 it is Double bearing 52 mounted for the impression cylinder.
  • the cylinder core 36 and the Printing cylinder sleeve 38 are shown in dash-dot lines.
  • the ejection and retractor 32 shown. This device is on the same Height as the axis of the impression cylinder defined by the double bearing 52.
  • the carriage 26 is driven by an electronic control unit 54, into which the diameter of the impression cylinder is entered, controlled that the ejector 42 acts on the pressure cylinder sleeve 38 but not the End face of the cylinder core 36.
  • FIG. 5 shows the cylinder core 36 'and the pressure cylinder sleeve 38' as an example. of a printing cylinder with a larger diameter is shown in dash-dot lines. The associated position of the carriage 26 is also indicated by dash-dotted lines.
  • the ejection and retraction device could 32 also arranged on the upper or lower vertex of the printing cylinder his. In this case, however, it should also be adjustable in height to allow adaptation to different diameters of the printing cylinder.
