Definitions

  • the invention relates to a clamping device for printing plates according to the preamble of claim 1. Furthermore, the invention relates to a forme cylinder according to the preamble of claim 10.
  • Printing units of printing machines such. As of web presses, have a form cylinder, a transfer cylinder, an inking unit and preferably a dampening unit.
  • On the form cylinder pressure plates are usually arranged, which is why the form cylinder are also referred to as a plate cylinder.
  • clamping devices which are integrated in a clamping channel of the forme cylinder. With the help of such a clamping device, a leading end and / or a trailing end of at least one thrust plate to be clamped in the clamping channel can be clamped.
  • Clamping devices known from practice have a clamping element and an actuating element, wherein both the clamping element and the actuating element are integrated into a clamping channel of a forme cylinder.
  • the clamping element can be transferred between two positions, namely between a first position in which the clamping element clamps the leading end and / or the trailing end of the or each pressure plate, and a second position in which the clamping element the leading end and / or the trailing end of the or each pressure plate releases.
  • clamping devices for printing plates have the disadvantage that they have a relatively complex structure.
  • the present invention seeks to provide a novel clamping device for printing plates with a simple structure and a form cylinder with such a clamping device.
  • the clamping element is adjustable exclusively in the radial direction of the forme cylinder and the actuating element exclusively in the axial direction of the forme cylinder, such that depending on the axial relative position of the actuating element to the clamping element, the clamping element either due to a spring force at least one clamping spring for clamping the leading end and / or the trailing end of the or each pressure plate radially outward displaceable or counter to the spring force of the or each clamping spring for releasing the leading end and / or the trailing end of the or each pressure plate radially inwardly displaceable.
  • the clamping device according to the invention for printing plates has a relatively simple structure.
  • the clamping device according to the invention comprises a clamping element, which is adjustable only in the radial direction of the forme cylinder, and an actuating element, which is adjustable only in the axial direction of the forme cylinder.
  • the leading end and / or the trailing end of the or each pressure plate are either clamped or released in the clamping channel of the clamping element.
  • the clamping element cooperates with at least one clamping spring.
  • Fig. 1 . 3 and 5 show in each case schematic cross-sections through a form cylinder 10 according to the invention a printing press in the region of a clamping channel 11 of the forme cylinder 10, wherein in the clamping channel 11 of the forme cylinder 10, a clamping device 12 is integrated for printing plates.
  • Fig. 2 . 4 and 6 show different perspective views of assemblies of the clamping device 12 according to the invention.
  • the clamping device 12 which is integrated into the clamping channel 11 of the forme cylinder 10, comprises a clamping element 13 and an actuating element 14.
  • the clamping element 13 serves to clamp a leading end and / or a trailing end of at least one pressure plate.
  • the actuating element 14 is used to actuate the clamping element 13 for transferring the same between two positions, namely between a first position in which the clamping element 13 clamps the leading end and / or the trailing end of the or each pressure plate, and a second position in which the clamping element thirteenth releases the leading and / or trailing end of the or each pressure plate.
  • the clamping element 13 is adjustable exclusively in the radial direction of the forme cylinder 10.
  • the actuating element 14, however, is adjustable only in the axial direction of the forme cylinder 10.
  • the clamping element 13 takes one of the two positions, either the first position in which the clamping element 13 clamps the leading end and / or the trailing end of the or each pressure plate, or the second position in which the clamping element 13 releases the leading end and / or the trailing end of the or each pressure plate.
  • At least one clamping spring 15 cooperates with the clamping element 13, which acts on a radially inner surface of the clamping element 13 and the same caused by the spring force radially outward into the first position, in which the clamping element the leading end and / or the trailing end of the or each pressure plate jams, presses.
  • the clamping element 13 is displaceable against the spring force of the or each clamping spring 15 for releasing the leading end and / or the trailing end of the or each pressure plate radially inward into the second position.
  • the first actuating element 14 are associated with the first bearing 16, which cooperate with the clamping element 13 associated guide curves 17.
  • the guide curves 17 are displaceable together with the clamping element 13 exclusively in the radial direction.
  • the first bearing 16 are displaceable together with the actuating element 14 exclusively in the axial direction. Then, if like in Fig.
  • the actuating element 14 to the clamping element 13 and thus the first bearing 16 relative to the guide curves 17 assume an axial relative position, in which the first bearing 16 are aligned with low points of the guide curves 17, the or each clamping spring 15 presses the clamping element 13 radially outward in the first position in which the clamping element 13 clamps the leading end and / or the trailing end of the or each pressure plate.
  • Fig. 1 and 2 lie in this axial relative position, the first bearing 16 is not on the guide curves 17, so that the spring force of the or each clamping spring 15 is fully effective and the clamping member 13 can be pressed with maximum spring force radially outward.
  • the clamping element 13 is displaceable exclusively in the radial direction of the forme cylinder 10, wherein the axial position of the clamping element 13 is fixed by lateral stops 18.
  • the stops 18 continue to serve as lateral stops for the actuating element 14 in the circumferential direction of the forme cylinder.
  • the actuating element 14 is displaceable exclusively in the axial direction of the forme cylinder, its radial position being fixed by a section 19 of an insert element 20, this section 19 of the insert element covering the actuating element 14 radially on the outside.
  • the portion 19 of the insert member 20 defines together with a portion 21 of the forme cylinder 10, a gap 22 in which for clamping the leading end and / or the trailing end of the or each pressure plate, a projection 23 of the clamping member 13 in the first position thereof (see Fig. 1 . 3 ) intervenes.
  • the clamping element 13 is formed such that the projection 23 leading and trailing end clamped at equal angles.
  • the actuating element 14 in addition to the first bearings 16, which cooperate with the guide curves 17 of the clamping element 13, further comprises second bearings 24, 25.
  • the second bearing 24 are radially inward and the second bearings 25 are positioned radially outward.
  • the second bearing 24 roll during the axial displacement of the actuating element 14 relative to the clamping element 13 on a radially inner surface of the clamping channel 11 from.
  • the second bearings 25 roll in the axial displacement of the actuating element 14 relative to the clamping element 13 on a surface of the insert element 20 from. This is best Fig. 3 be removed.
  • the second bearings 24, 25 serve for the radial fixation or mounting of the actuating element 14.
  • the clamping element 13 and the actuating element 14 are integrated into the clamping channel 11 of the forme cylinder 10 in such a way that they are positioned side by side in the circumferential direction.
  • the first bearings 16 are associated with the actuating element 14 and the guide curves 17 of the clamping element 13 on opposite, adjacent side surfaces thereof.
  • the guide curves 17 are assigned to the clamping element 13 and the first bearings 16 to the actuating element 14. In contrast, it is also possible that the guide curves are associated with the actuating element and the first bearing the clamping element.
