Definitions

  • the invention relates to a device for fastening and clamping of printing plates with folded ends a plate cylinder of a rotary printing press the preamble of claim 1.
  • EP 01 24 008 A2 also describes a forme cylinder a device for clamping flexible Pressure plates with clamping devices for folded ends a printing plate. These clamping devices are in a pit arranged and with a triangular segment body formed a hanging edge, the outer surface in tensioned condition of the pressure plate the pit gap covers and corresponds to the contour of the forme cylinder.
  • the generic US-PS 18 58 305 shows one Device for fastening and tensioning printing plates with folded ends on a plate cylinder one Rotary printing press. It is one by one Axis pivotable, axially extending Hooking nose became known. Are in the hanging nose two - in relation to the axis of rotation - opposite surfaces provided with two Interacting support surfaces on the plate cylinder. At the Hanging nose are means to initiate a Torque and a bearing present it enables the contact surfaces on the hooking nose in contact with the support surfaces on the plate cylinder are feasible.
  • the invention has for its object a Device for fastening and tensioning printing plates with folded ends on a plate cylinder one To create rotary printing press.
  • the advantages that can be achieved with the invention exist in particular in that with the invention Device also overprinting a hanging nose is possible during the printing process. Through the The device according to the invention becomes a non-spit Storage of the hanging nose guaranteed. Pressure disorders due to movements of the hooking nose are avoided. A molding compound of a mounting of a clamping spindle is in the Exciting state free of forces.
  • the device according to the invention is in the drawing shown and is described in more detail below.
  • a plate cylinder 1 of a rotary printing machine has a left and right hooking nose 2, 3, respectively of outer and inner surface 4, 6, 7, 8 are formed.
  • the respective outer surface 4, 6 closes with the Inner surface 7, 8 has an acute-angled opening angle Alpha of, for example, 45 ° and is at one Curvature of a contour 9 of the plate cylinder 1 adapted.
  • hook-in lugs 2, 3 run parallel to one Axis of rotation 5 of the plate cylinder 1 and are on it Outer surface 4, 6 of the contour 9 of the plate cylinder 1 limited.
  • a channel 11 runs axially with, for example U-shaped cross section.
  • one Seal 12 e.g. B. a round cord inserted.
  • a printing plate 13 or a carrier plate Blanket is with its folded ends 14, 16 in the hook-in lugs 2, 3 hooked in. Folded legs 17, 18 of these ends close with the pressure plate also an opening angle alpha of, for example 45 °, which is adapted to the hanging lugs 2, 3.
  • the left hooking lug 2 is directly in the Plate cylinder 1 molded while the right one Hanging nose 3 pivotable, for example, on one Clamping spindle 19 is arranged. It is also possible Execute both hook-in lugs 2, 3 pivotably. In a clamping state sets the clamping spindle 19 with the Attach the nose 3 to the contour 9 of the plate cylinder 1 continuously, continuously.
  • the Clamping spindle 19 is in a cylinder pit 27 in one hardened, shell-shaped molding compound 28 pivoted about its axis of rotation 20.
  • the Swiveling movement for tensioning and relaxing the Pressure plate 13 is by means of a front End of the clamping spindle 19 arranged worm gear 29 generated.
  • This self-locking worm gear 29 consists essentially of a toothed segment 31, one first worm 32, a worm wheel 33 and one second screw 34.
  • the first screw 32 is common with the worm wheel 33 on a rotatably mounted Shaft 36 attached.
  • This shaft 36 is perpendicular to Clamping spindle 19 on one end of the plate cylinder 1 arranged in two bearings 37, 38.
  • the snail 32 this shaft 36 engages in the face fastened Tooth segment 31 of the clamping spindle 19, while the Worm gear 33 meshes with the second worm 34.
  • the second screw 34 is present Embodiment with a hexagon 39 for Initiate a rotary motion, but there are other actuators, e.g. B. stepper motors, possible.
  • the worm gear 29 are also other drives for generating the swivel movement possible.
  • the operation of the device according to the invention is as follows:
  • the pressure plate 13 is first with its folded end 14 in the fixed hanging lug 2 at the beginning of the print and z. B. after one revolution with its end 16 hooked into the open, that is to say pivoted outward hooking nose 3 at the end of the print.
  • the hooking nose 3 instead of the molding compound 28, another storage can also be used be arranged for the hooking nose 3. So can for example, the hook-in nose 3 only at its ends be supported in the axial direction in two bearing rings. Of the The inner diameter of the bearing rings is slightly larger than the outside diameter of those stored in it Clamping spindle 19.
  • Hanging nose 3 and plate cylinder 1 are with surfaces 22, 24; 23; 26 provided which form a positive guidance. Due to this forced guidance, the hook-in nose 3 without play out of the channel 11 in the direction of contour 6 pressed against the plate cylinder 1.
