Definitions

  • the invention relates to a printing press.
  • the invention is concerned with a system for replacing a printing cylinder and / or an inking roller in the inking unit of a flexographic printing machine.
  • European patent application 95 116 394 describes a device for changing a pressure cylinder sleeve, which is provided with bearing pins at both ends.
  • the bearing journals are each mounted in a hinged bearing on a bearing block which can be moved approximately radially with respect to the impression cylinder in order to put the impression cylinder sleeve on and off against an impression cylinder.
  • An axially extending through the pressure cylinder sleeve shaft can be clamped at one end in such a way that the pressure cylinder sleeve can be lifted vertically with the help of the shaft and the lifting system after opening the bearing in a position in which the pressure cylinder sleeve pull axially from the shaft leaves.
  • the bearing blocks for the printing cylinder are each guided on a guide rail which is mounted on the upper side of a console attached to the relevant side part of the printing machine.
  • the inking roller is mounted in a corresponding manner in bearing blocks, which can also be moved radially with respect to the impression cylinder for turning the inking roller on and off.
  • the bearing blocks for the inking roller can be guided on the same guides as the bearing blocks for the printing cylinder.
  • the lifting system for lifting the printing cylinder sleeve and the inking roller requires a great deal of design. If several inking units are arranged in the same way on the same impression cylinder, the vertical distance between the inking units must also be relatively large so that there is sufficient space for lifting the printing cylinders and inking rollers. In addition, very laborious adjustment work in connection with the fastening of the brackets to the side parts of the printing press and in connection with the assembly of the guide rails on the brackets are required.
  • the object of the invention is to provide a printing press which has a simplified structure and yet permits simple replacement of the printing cylinders and / or inking rollers.
  • the invention accordingly relates to a printing press with preferably a plurality of inking units arranged on a common impression cylinder, each with at least one roller body (impression cylinder or inking roller), which is held with its opposite ends in two bearing blocks which can be moved approximately radially with respect to the impression cylinder and with one end is mounted in a hinged bearing attached to the bearing block there, while its other end is clamped like a cantilever in a holder, the holder and the hinged bearing being movable relative to one another in such a way that the roller body can be moved out of the latter after the hinged bearing has been opened is and can then be removed in the axial direction, characterized in that the fold-out bearing is open in the opened state in the direction of movement of the associated bearing block and by moving this bearing block in relation to the counter pressure ylinder is approximately radial direction in the position that allows the axial removal of the roller body.
  • the pedestals are moved only linearly in a single direction, namely approximately radially to the impression cylinder, both when starting and stopping at the impression cylinder and when changing the impression cylinder, and it is therefore not an additional lifting system for lifting the impression cylinder and the inking roller from the hinged ones Storage required. Only one drive and guide system is required for the linear movement of the pedestals during the various work processes. As a result, considerable structural simplification is achieved overall. In addition, a closer arrangement of the inking units on the impression cylinder is possible, since no space is required for the vertical movements of the printing cylinders and inking rollers.
  • the invention further relates to a printing press with an intermediate 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), which is supported with its opposite ends in bearing blocks, and with guides held on the side parts, on which the bearing blocks are guided such that the roller body is approximately is radially movable with respect to the impression cylinder, characterized in that the guides are attached to the inner surfaces of support arms formed in one piece with the respective side parts and are positioned on the support arms by means of pins which engage in bores in the support arms.
  • the guides are attached to the inner surfaces of support arms formed in one piece with the respective side parts and are positioned on the support arms by means of pins which engage in bores in the support arms.
  • the support arms formed in one piece with the side parts for the different inking units can each be connected to one another at the free ends, so that only window-like recesses are formed in the side parts, which allow the printing cylinders and inking rollers to be pulled out axially.
  • the printing press has a machine frame with two parallel, plate-shaped side parts 10, between which an impression cylinder 12 is mounted.
  • a plurality of inking units 14 are arranged on the circumference of the impression cylinder 12, only two of which are shown in FIG.
  • Each inking unit has a printing cylinder 16 which can be set on the impression cylinder 12 and an inking roller (anilox roll) 18 which can be set on the printing cylinder.
  • Each printing cylinder 16 and each inking roller 18 is provided with stub axles 20 at both ends and is supported in bearing blocks 22, 24, 26.
  • the corresponding bearing blocks of the printing cylinder 16 and the inking roller 18 of each inking unit are guided on a common guide 28 and can be moved independently of one another in the longitudinal direction of the guides 28 with the aid of known drive means 30 (FIG. 5), so that the inking roller 18 extends from the circumference of the printing cylinder 16 and the impression cylinder can be moved away from the circumference of the impression cylinder 12.
  • 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.
  • the side part 10 facing the viewer in FIG. 1 has a window-like recess 32 for each inking unit 14, through which the printing cylinder 16 and the inking roller 18 of the inking unit in question are accessible.
  • the areas of the side wall 10 which lie between the cutouts 32 or below these cutouts serve as support arms 34 to which the guides 28 are fastened.
  • the side part 10 facing away from the viewer in FIG. 1 has only a narrower slot-shaped recess 36 instead of the window-like recess 32.
  • At least two of the guides 28 designed as prism-shaped rails are on the mutually facing inner surfaces of the side walls 10 assembled and positioned there by means of pins 40 (FIG. 5) engaging in bores 38 of the side parts.
  • the bearing blocks 22 are provided with hinged bearings 42, the bearing covers of which are articulated on the bearing block in such a way that the stub shaft 20 can be moved laterally out of the bearing block after opening the bearing cover, that is in the direction parallel to the guide 28 .
  • the bearing blocks 22, 24 and 26 are first moved into the position shown in FIG. 3, in which the printing cylinder 16 is set apart from the impression cylinder 12 and the inking roller 18 from the printing cylinder 16 is turned off. Then the bearing caps are opened. Thereafter, the bearing blocks 22 alone are moved into the position shown in FIG. 4, so that they release the shaft end 20. The printing cylinder 16 and the inking roller 18 are then held only at their end not visible in FIG. 4 by the bearing blocks 24 and 26.
  • the bearing blocks 26 attached to the outside of the left side part 10 in FIG. 5 serve to absorb the tilting moments of the printing cylinder and the inking roller. However, they can optionally be replaced by any other shaft stub chuck.
  • the printing cylinder 16 and the inking roller 18 can be pulled out of their bearings on the bearing blocks 24, 26 axially, for example with the aid of a robot, ie towards the viewer, and removed from the machine frame through the window-like recess 32 will.
  • a new printing cylinder and a new inking roller can be used.
  • the printing cylinder 16 and the inking roller 18 are completely replaced
  • the shaft ends 20 are constantly clamped in the bearing blocks 24, 26 on the rear of the machine frame, and only the sleeves are passed through the window-like recesses 32 are pulled off and replaced by the printing cylinder or the inking roller.
  • the hinged bearings formed by the bearing blocks 22 are shown as plain bearings. In practice, however, ball bearings are arranged on the shaft ends 22 in a known manner. These ball bearings always remain on the stub shafts and lie with their outer ring in the bearing block and are secured by the bearing cover.
  • the bearing cover is provided with locking devices, not shown, so that it can be locked in the closed position.
  • the bearing blocks are preferably mounted on the guides 28 with the aid of circulating ball systems, so that they can be moved easily on the guides.
  • the guides 28 lie laterally next to the side parts 10 of the machine frame, the weight forces of the inking unit can be stably absorbed by the pins 40, especially when, as in the example shown, the guides rest snugly on the side parts 10. It goes without saying that the guides 28 can additionally be secured to the side parts by screws and the like, not shown.
