Definitions

  • the invention relates to a printing press with a between side parts of the machine frame mounted impression cylinder and preferably several inking units, each with at least one roller body (printing cylinder or inking roller) with its opposite ends in Bearing blocks is stored, and with guides held on the side parts, on which the bearing blocks are guided such that the roller body approximately is movable radially with respect to the impression cylinder.
  • the invention is concerned with a system for changing a printing cylinder and / or an inking roller in the inking unit of a flexographic printing machine.
  • a device described for changing a pressure cylinder sleeve on both ends is provided with trunnions.
  • the trunnions are each hinged Bearing stored on a pedestal, which is used to turn the Printing cylinder sleeve to an impression cylinder approximately radially with respect is movable on the impression cylinder.
  • One axially through the impression cylinder sleeve extending shaft can be clamped at one end in a lifting system, that the pressure cylinder sleeve with the help of the shaft and the lifting system opening the bearings can be lifted vertically into a position, in which the pressure cylinder sleeve can be removed axially from the shaft.
  • the bearing blocks are typically for the impression cylinder each guided on a guide rail on the Top of one attached to the relevant side part of the printing press Console is mounted.
  • the inking roller is in a corresponding manner can be lifted out in bearing blocks, which are used to switch the inking roller on and off to the impression cylinder also radially with respect to the impression cylinder are movable.
  • the bearing blocks for the inking roller can on the same guides as the bearing blocks for the printing cylinder.
  • the lifting system requires lifting the printing cylinder sleeve and the inking roller a high constructive Expenditure. If in the usual way several inking units on the same Impression cylinders are arranged, the vertical distance must also be relatively large between the inking units, so that there is sufficient freedom for lifting the printing cylinders and inking rollers. About that in addition, very tedious adjustment work is involved in the assembly with the attachment of the brackets to the side parts of the printing press and in connection with the assembly of the guide rails the consoles required.
  • the object of the invention is to provide a printing press that is simplified Has structure and yet easy replacement of Printing cylinders and / or inking rollers permitted.
  • the guides on the inner surfaces are in one piece attached with the respective side parts trained support arms.
  • the holes used to position the guides can be used in the Manufacture of the side panels are precisely drilled so that a correct one Positioning and alignment of the guides for the pedestals guaranteed is.
  • the support arms designed in one piece with the side parts for the various Inking units can be connected to each other at the free ends be, so that only window-like recesses in the side parts are formed, the axial extraction of the printing cylinder and inking rollers allow.
  • a considerable constructive simplification is achieved.
  • the printing machine has a machine frame two parallel, plate-shaped side parts 10, between which an impression cylinder 12 is stored.
  • On the circumference of the impression cylinder 12 several inking units 14 are arranged, of which only two in FIG. 1 are shown.
  • Each inking unit has one on the impression cylinder 12 adjustable pressure cylinder 16 and one adjustable to the pressure cylinder Ink application roller (anilox roller) 18 on.
  • Each printing cylinder 16 and each inking roller 18 is provided at both ends with stub axles 20 and in Bearing blocks 22, 24, 26 stored.
  • the corresponding pillow blocks the printing cylinder 16 and the inking roller 18 of each inking unit are on a common guide 28 guided and with the help of known drive means 30 ( Figure 5) independently of one another in the longitudinal direction of the guides 28 movable, so that the inking roller 18 from the circumference of the printing cylinder 16 and the impression cylinder from the circumference of the impression cylinder 12 can be moved away.
  • the guides 28 accordingly run approximately radially with respect to the axis of rotation of the impression cylinder 12.
  • the side parts 10 of the machine frame are dimensioned so that the Inking units 14 are almost completely between these side parts.
  • This in 1 shows the side part 10 facing the viewer for each inking unit 14 a window-like recess 32 through which the pressure cylinder 16 and Ink application roller 18 of the inking unit in question are accessible.
  • the between the recesses 32 or below these recesses Areas of the side wall 10 serve as support arms 34 on which the guides 28 are attached.
  • the side part 10 facing away from the viewer in FIG. 1 has only a narrower instead of the window-like recess 32 slot-shaped recess 36.
  • At least two of the guides designed as prismatic rails 28 are on the mutually facing inner surfaces of the side walls 10 assembled and there engaging in holes 38 of the side panels Pins 40 ( Figure 5) positioned.
  • the bearing blocks 22 are with hinged bearings 42 provided, the bearing caps are hinged to the bearing block that the Shaft stub 20 laterally after opening the bearing cover, that is in the direction parallel to the guide 28, can be moved out of the bearing block.
  • the bearing blocks 22, 24 and 26 When the printing cylinder 16 and the inking roller 18 of an inking unit 14 should be replaced, the bearing blocks 22, 24 and 26 first moved to the position shown in Figure 3, in which the impression cylinder 16 is turned off by the impression cylinder 12 and the inking roller 18 is turned off by the pressure cylinder 16. Then the bearing caps open. Thereafter, the bearing blocks 22 alone are shown in FIG Position continued so that they release the shaft end 20. Of the Printing cylinder 16 and the inking roller 18 are then only on their 4 not visible end held by the bearing blocks 24 and 26.
  • the bearing blocks attached to the outside on the left side part 10 in FIG. 5 26 serve to absorb the tilting moments of the pressure cylinder and the inking roller. However, you can choose to use any other Clamping device for the shaft end to be replaced.
  • the printing cylinder 16 and the inking roller 18 While in the example shown the printing cylinder 16 and the inking roller 18 to be completely replaced, it is in another embodiment also possible to use a so-called sleeve system, in which the printing cylinder 16 and / or the inking roller 18 on their Wear an interchangeable sleeve. In this case they remain Stub shaft 20 constantly in the bearing blocks 24, 26 on the back of the Machine frame clamped. and only the sleeves are through the window-like recesses 32 from the printing cylinder or the inking roller removed and replaced.
  • bearing blocks 22 formed hinged bearings shown as plain bearings.
  • ball bearings on the shaft ends 22 in a known manner arranged. These ball bearings always remain on the shaft ends and lie with their outer ring in the bearing block and are through the bearing cover secured.
  • the bearing cover is with locking devices, not shown provided so that it can be locked in the closed position can.
  • the bearing blocks are preferably with the help of recirculating ball systems Guides 28 stored so that they move easily on the guides to let.
  • the guides 28 laterally lie next to the side parts 10 of the machine frame, the weight forces of the inking unit are stably received by the pins 40, especially if, as in the example shown, the guides are full of Side panels 10 rest. It is understood that the guides 28 in addition secured by screws and the like, not shown, on the side parts can be.
