Definitions

  • the invention relates to a device for registerable mounting of a printing plate according to the preamble of claim 1.
  • the invention has for its object to provide a device for clamping a printing plate on a plate cylinder of a rotary printing press, so that the clamped printing plate on the plate cylinder is displaceable and lockable.
  • a cylinder pit provided for receiving the clamping device is made very narrow, so that a circumference of the plate cylinder can be used almost completely.
  • the clamping device according to the invention it is also possible to use it on plate cylinders which are reversible in the direction of rotation.
  • An axially parallel pit 2 is incorporated in a plate cylinder 1 and is delimited at the ends by bearer rings 6, 7.
  • the pit 2 has in its side walls 3, 4 in each case a continuous groove 8 reaching as far as the bearer rings 6, 7; 9 for receiving an adjusting shaft 11; 12 on.
  • the actuating shafts 11, 12 have, within their shaft body, as seen in the axial direction, at intervals eccentrically to the axis 18; 20 of the control shaft 11; 12 arranged truncated cones 13, 14.
  • the adjusting shaft 11 is axially displaceable on both sides of the plate cylinder 1 in bores 16, 17 in the bearer rings 6, 7 and at the same time is pivotably mounted about its shaft axis 18.
  • the actuating shaft 1 has a hexagon head 19; 21 on.
  • Brackets 22, 23 screwed to the front of the plate cylinder 1 serve to accommodate adjusting screws 24, 26.
  • the adjusting screws 24, 26 hit with their heads 27, 28 against the hexagon head 19, 21 of the adjusting shaft 11.
  • the actuating shaft 12 is pivotally but not displaceably mounted in brackets 29, 31 fastened on the face to the plate cylinder 1.
  • brackets 29, 31 fastened on the face to the plate cylinder 1.
  • At the bottom 32 of the pit 2 are two clamping bars 33, 34 for tensioning about a vertical, for entangling about a horizontal position and at the same time axially displaceable.
  • ball joint heads 37, 39 which are guided and held by means of two slot guides 36, 38 running parallel to the pit 2 in the base 32.
  • the ball joint heads 37, 39 are each arranged in the middle under the clamping bars 33, 34.
  • the side register is adjusted by axially displacing the clamping bars 33, 34 by means of adjusting screws 41 to 44 screwed into the ends of the clamping bars 33, 34.
  • adjusting screws 41 to 44 screwed into the ends of the clamping bars 33, 34.
  • the adjusting shaft 11 each has a circumferential groove 46 directly next to the hexagon head 19, 21; 47 into which a guide pin 48; 49 engages.
  • the guide pin 48; 49 sits firmly on a first end of a roller lever 51; 52.
  • the roller lever 51; 52 has a bore 53; 54, by means of which it is centered around a cylinder-fixed pin 56; 57 is rotatably mounted.
  • the roller lever 51; 52 a rotatably mounted roller 58; 59 on.
  • the role 58; 59 is in constant contact with an actuating pin 61; 62, which in a bore 63; 64 within the bearer ring 6; 7 is axially displaceably mounted.
  • the actuating pin 61; 62 provides the connection between the roller 58; 59 and the adjusting screw 42; 44 of the clamping strip 34.
  • the clamping strips 33, 34 have, at a distance from the truncated cones 13, 14 of the actuating shafts 11, 12, plungers 66 distributed over their length; 67, which are directly on a jacket surface 65, 70 of the truncated cones 13; 14 of the control shaft 11; Support 12.
  • a plurality of compression springs 74 are arranged, the ends of which are attached to the inner sides 76, 77 of the tensioning strips 33, 34 and push them apart in the direction of the side walls 3, 4, so that the plungers 66, 67 are in constant contact with the Truncated cones 13, 14 are held.
  • the actuating shaft 11; 12 To interlock the on the clamping bars 33; 34 attached pressure plate 73 on the plate cylinder 1 is the actuating shaft 11; 12 provided.
  • the inclinations of the truncated cone surfaces 65, 70 of the actuating shaft 11 are oriented such that an axial displacement of the actuating shaft 11 causes the clamping bar 33 to pivot parallel to the base 6 of the pit 2 around the ball joint head 37.
  • the jacket surfaces 70 of the truncated cones 14 of the actuating shaft 34 are each arranged parallel to the opposite jacket surfaces 65 of the truncated cones 13, so that the clamping strips 33, 34 are always displaced in a parallelogram-like manner.
  • the tappets 66 slide on the outer surfaces 65 of the truncated cones 13, so that the tensioning bar 33 is rotated counterclockwise around the ball joint head 37.
  • the groove 46; 47 takes the guide pin 48; 49 with and thus pivots the roller lever 51; 52 around the pin 56; 57 clockwise.
  • the clamping bar 34 is on the second end of the roller levers 51, 52 mounted rollers 58, 59 shifted to the left against the tensioning bar 33.
  • the tensioning strip 34 caused by the contact of the tappets 67 with the casing surfaces 70 of the truncated cones 14, is pivoted counterclockwise and parallel to the tensioning strip 33.
  • the adjusting screws 41 to 44 screwed into the clamping bars 33, 34 are inserted into or out of the respective clamping bar 33; 34 screwed in or out.
  • the adjusting screw 43; 44 on the opposite end of the tensioning strip must then be screwed out again according to previous screwing in to lock the tensioning strips 33, 34.
  • the clamping bar 33 is in this case axially positively guided by the slot guide 36.
  • the tensioning strip 34 is adjusted accordingly by means of the adjusting screws 43, 44 against the actuating bolts 61, 62.
  • the pressure plate 73 which is inserted with its front and rear edges 71, 72 into the grooves 68, 69 of the clamping strips 33, 34, is tensioned by pivoting the adjusting shaft 11; 12 depending on which pressure plate end is to be tensioned or depending on the direction of rotation of the plate cylinder 1.
  • the truncated cones 13, 14 act through their eccentric arrangement like levers on the tappets 66, 67 of the clamping strips 33, 34, thereby causing them to Pit center can be pivoted against the compression springs 74.
  • the actuating shafts 33, 34 are locked in the tensioned position.
