Definitions

  • the invention relates to a device for carrying out a printing plate change on a forme cylinder of a printing press according to the preamble of claim 1.
  • the DE 44 40 239 C2 discloses a device designed as a rolling element for performing a printing plate change on a forme cylinder of a printing press.
  • the rolling element disclosed therein is used in the printing plate change the pressing of a flexible printing plate to the forme cylinder of a printing unit of a printing press.
  • the rolling element according to DE 44 40 239 C2 has several arranged in the longitudinal direction of the forme cylinder, individually engageable with the forme rolls, at least one first role in the assembly of the printing plate and at least one second role in the disassembly of the printing plate in the region of the pressure plate to the forme cylinder is adjustable. According to the rolling element DE 44 40 239 C2 Although an exact pressing of the printing plate to the forme cylinder during printing plate change is possible, however, the device according to the prior art does not allow exact alignment of the printing plate relative to the forme cylinder.
  • a device for carrying out a printing plate change on a forme cylinder of a printing machine which has an aligning element on both sides of the rolling element having a plurality of rollers, in order to align a printing plate to be clamped during the printing plate change relative to the forme cylinder.
  • the alignment elements in this case have a gripper and a cooperating with the gripper clamping piece, wherein an exciting pressure plate between the gripper and the clamping piece can be clamped.
  • the present invention is based on the problem to provide a novel device for performing a printing plate change on a forme cylinder of a printing press.
  • the invention extends parallel to the rolling element a plurality of aligning elements carrying bar, wherein between each two adjacent alignment elements in each case a pressure plate before clamping them in a chucking channel of the forme cylinder is aligned in register aligned.
  • the device according to the invention With the device according to the invention, a plurality of printing plates can be aligned in register relative to the forme cylinder at the same time before clamping them on the forme cylinder. Furthermore, the device according to the invention is structurally simple and can be realized at relatively low cost.
  • the strip which is upstream of the rolling element, associated with at least two centering pins which are insertable for aligning the strip and thus the alignment elements relative to the forme cylinder in corresponding recesses of the forme cylinder.
  • hold-down elements extend between adjacent alignment elements, with each hold-down element being able to hold down a pressure plate which is to be aligned in register with the corresponding alignment elements and to be tensioned in the clamping channel of the forme cylinder during the printing plate change.
  • Fig. 1 to 3 show different views of a device 10 according to the invention for performing a plate change on a forme cylinder of a printing press, wherein Fig. 1 and 2 show the device 10 according to the invention together with a forme cylinder 11.
  • the forme cylinder 11 has, in the embodiment shown, two diametrically opposite sections via a respective clamping channel 12 (see FIG Fig. 1 ) so as to clamp in the circumferential direction of the forme cylinder 11, two printing plates in a row on the same.
  • the forme cylinder 11 has an axial width, which makes it possible, viewed in the axial direction of the forme cylinder 11, to clamp four pressure plates next to one another.
  • the in Fig. 1 and 2 Form cylinder shown is therefore designed as a so-called 4/2-forme cylinder, it can be seen in the same direction in the axial direction four printing plates side by side and seen in the circumferential direction two printing plates are stretched one behind the other.
  • the device 10 according to the invention has a rolling element 13 (see Fig. 3 ), wherein the rolling element 13 has a plurality of rollers 14, which serve the pressing of exciting pressure plates to the forme cylinder 11 during printing plate change.
  • the design of such a rolling element 13 is familiar to the person skilled in the art and requires no further explanation.
  • the device 10 has a parallel to the rolling element 13 extending bar 15, wherein the bar 15 carries a plurality of alignment elements 16.
  • the bar 15 carries a total of five alignment elements 16.
  • Between each two adjacent alignment elements 16 is a respective pressure plate before the clamping thereof in a clamping channel 12 of the forme cylinder 11 in register relative to the forme cylinder 12 aligned.
  • the strip 15 is assigned a centering pin 17 at each end.
  • the centering pins 17 serve to align the strip 15 and thus the alignment elements 16 relative to the forme cylinder 11, for which purpose the centering pins 17 are inserted into corresponding recesses 18 of the forme cylinder 11.
  • the device 10 in addition to the rolling element 13 and the alignment elements 16 carrying bar 15, the device 10 according to the invention further has hold-down elements 19. Between each two adjacent alignment elements 16 each extending a hold-down element 19, with each hold-down element 19 a registering to be aligned with the corresponding registration elements 16 pressure plate Pressure plate change is untenable.
  • the alignment elements 16 are designed as cuboid blocks.
  • the register-containing alignment of a pressure plate serving side walls 20 (see in particular Fig. 3 ) have a phase over which a printing plate can be aligned in register.
  • the register-containing alignment of a printing plate serving side walls 20 are according to Fig. 3 preferably divided into two sections, namely a first, phased and a second, non-phased section.
  • the first, chamfered portions of the side walls 20 are projected opposite to a chucking channel of the forme cylinder 11, while the second, non-chamfered portions of the side walls 20 are projected into the chucking channel of the forme cylinder 11.
  • a pressure plate after being aligned with the first, chamfered portions of the side walls 20, reaches the region of the second, non-chamfered portions of the side walls 20 of the aligning elements 16, the pressure plate can be in registration with one end thereof into the corresponding chucking channel of the forme cylinder 11 come in and be tense in the same.
  • a clamping device is integrated, which is familiar to the person skilled in the art and requires no further explanation.
  • the alignment elements 16 are designed as piezo elements.
  • Such piezoelectric elements can be controlled or changed via a control station in its outer shape or geometry, so as to ensure register matching to minimize a so-called fan-out effect.
  • the device 10 according to the invention is fixed to angled fastening elements 22 via support elements 21 which are positioned on both sides of the device 10, wherein the device 10 is fastened or mounted on a frame of the printing press via struts 23 engaging on the fastening elements 22.
