Definitions

  • the invention relates to a device for precise clamping and clamping of printing plates on the plate cylinder according to the preamble of the first claim.
  • a device according to the preamble of claim 1 is known from DE-PS 3 516 682 and enables, in a manner known per se, the clamping of the printing plate at the beginning and end of printing by rotating the eccentric shafts associated with the corresponding tensioning rails by means of a hand-operated tool.
  • the subsequent tensioning of the pressure plate is carried out manually using a tool in which the tensioning rail at the end of the print is displaced almost in the circumferential direction by a central actuating device and a pressure bar.
  • the disadvantage here is that several manual manipulations on the cylinder channel are necessary and automatic re-tensioning is not guaranteed while the machine is running.
  • DE-OS 3 843 433 describes a device for rapid clamping of printing plates, the eccentric shafts causing the clamping and clamping on the cylinder side wall each being provided with double roller levers and for clamping, unclamping, clamping, relaxing via an actuator fixed to the frame after a corresponding angular positioning of the Plate cylinders are rotatable.
  • EP-A2 0 260 492 also describes a technically similar route, with the eccentric shafts on the cylinder side wall instead carry double simple lever arms and can be rotated by pulling or pushing through a frame-side actuator
  • DE-OS 3 843 395 shows a further device for precise rapid clamping.
  • the clamping and clamping device is assigned at least one common actuating device arranged on the machine frame and corresponding to the angular position of the plate cylinder at the time of clamping and clamping. Clamping and tensioning takes place via axially displaceable pull wedge gears, which can be moved by the actuating devices arranged on both sides of the cylinder side walls.
  • clamping is not possible while the machine is running.
  • Another disadvantage is that the forces for clamping, unclamping, tensioning and relaxing always act axially and must therefore be absorbed by the bearings of the plate cylinder.
  • the object of the invention is to expand the input-specified device so that a clamping and tensioning of the printing plate can be carried out precisely with a minimum of handling effort, regulating the tension of printing plates and their automatic re-tensioning is made possible uniformly over the entire width, in particular in the case of large-format printing plates and also the design disadvantages mentioned in the prior art can be avoided.
  • the plate cylinder 1 is supported on both sides by frame walls 2 of the printing press in bearings, not shown. In its cylinder channel it has 3 means for clamping and tensioning printing plates. 1, 3 and 5, these means are designed as a front and rear tensioning rail 4, 5 assigned to the beginning and the end of printing, each consisting of an upper clamping device 4.1, 5.1, a lower clamping device 4.2, 5.2 and actuatable by eccentric shafts 4.3, 5.3. These tensioning rails 4, 5 can be split or undivided tensioning rails.
  • the front clamping rail 4 is supported Tensioning screws 4.4 directly on the wall of cylinder channel 3.
  • the pressure plate is fixed in the front tensioning rail 4 in a known manner in a zero position, for example by means of dowel bolts.
  • the rear tensioning rail 5 is supported by tensioning screws 5.4 on a pressure bar 7 which runs and is displaceable parallel to the rear channel wall in a recess 6 machined there.
  • the pressure bar 7 has two recesses 8 one above the other with an inclined plane, which slide on wedge surfaces on counterparts 9, so that a movement of the pressure bar 7 parallel to the channel wall causes the pressure plate to be tensioned by a tensioning rail 5 displacing from the rear channel wall.
  • the tensioning device described which is to be counted in the prior art, thus represents a series connection consisting of a pre-tensioning device (pressure bar 7, recesses 8, counterparts 9) and the tensioning screws 5.4 for the final, adjusting tensioning.
  • the eccentric shafts 4.3, 5.3, as shown in FIGS. 1 to 3, have coupling sleeves 12 on both cylinder side walls 10 in openings 11 there, which advantageously terminate flat with the cylinder side walls 10.
  • the openings 11 in the cylinder side walls 10 are dimensioned such that maximum adjustability of the clamping rails 4, 5, in particular by the clamping screws 4.4, 5.4, is ensured (FIGS. 2 and 3).
  • the eccentric shafts 4.3, 5.3 are connected to the coupling sleeves 12 by way of compensating couplings 13, in particular in the Oldham design.
  • clamping tools 14 are movably inserted in the two frame walls, which, if appropriate Angular position of the plate cylinder 1 can be engaged by an axial movement into the coupling sleeves 12 of the pressure start or pressure end eccentric shaft 4.3, 5.3.
  • the end of the clamping tool 14 which engages in the coupling sleeve 12 is designed in a form-fitting manner with respect to the inner profile of the coupling sleeve 12.
  • the coupling sleeve 12 has an internal hexagon profile and the end of the clamping tool 14 an external hexagonal profile. The latter can also rejuvenate. (Fig. 2).
  • the rear part of the clamping tool 14 pointing away from the plate cylinder 1 is a piston rod 15 with a piston disk 16, which in turn is guided in a cylinder bore 16 'of the frame wall 2 (FIG. 2).
  • the cylinder bore 16 ' delimits a flange 17 attached to the frame wall 2
  • the cylinder bore 16' is delimited by a bearing part 18 attached to the frame wall 2.
  • Flange 17 guides the front part (shaft) of the clamping tool 14.
  • Bearing part 18 guides the end of the piston rod 15 in a bore.
  • the part of the clamping tool 14 which is in the frame wall 2 thus forms with the piston rod 15, piston disk 16, flange 17, bearing part 18 a double acting, ie Working cylinder that can be moved in two directions by applying pressure medium.
  • the pressure medium is fed into the two chambers of the working cylinder via bores 19 and 19 '.
  • the pressure medium is advantageously compressed air.
  • Flange 17 and bearing part 18 have corresponding seals with respect to frame wall 2 and clamping tool 14.
  • This bore and the shaft of the clamping tool 14 are in such a positive connection that the axial displaceability of the clamping tool 14 is not impaired.
  • the bore and shaft have a multi-groove profile.
  • Flange 17 rotatably guides lever 20, the free end of lever 20 is led out through a recess 17 '(FIG. 2b).
  • both compressed air cylinders 23 are installed in the machine in a predominantly vertical orientation, since most of the space is available in this way.
  • the pressure plate can be clamped or unclamped at the pressure start and pressure end by appropriate pressurization of compressed air with clamping tools 14 engaged on both sides in the coupling sleeves 14 of the pressure start, pressure end eccentric shafts 4.3, 5.3. As already mentioned, the clamping tools 14 are engaged or disengaged after the angular positioning of the plate cylinder 1.
  • a motor 25 is arranged between the front and rear clamping rails 4, 5, which drives an adjusting spindle 27 running parallel to the axis of the plate cylinder 1 via a joint 26.
  • a spindle nut 28 is seated on the adjusting spindle 27 and is firmly connected to the pressure bar 7 via a bridge 29.
  • the adjusting spindle 27 is guided as a shaft by means of an axial thrust bearing 30 through a support wall 31 and is supported at its end with a spherical end face by means of a pressure piece 32 on a further support wall 31 (FIGS. 3 and 4).
  • the spindle nut 28, that is also the pressure bar 7 is displaced parallel to the rear wall of the cylinder channel 3 via the adjusting spindle 27, which is supported on both sides. Since the adjusting spindle 27 moves parallel to the pressure bar 7, the thrust bearing 30 is embedded in a corresponding groove 31 'in the support wall 31 (FIG. 5).
  • the motor 25 is pivotably mounted at its rear end by means of a joint 25 'parallel to the bottom of the cylinder channel 3 (FIGS. 3 and 4).
  • the motor 25 is advantageously a compressed air motor, in particular a vane motor.
  • a tensioning lever 33 is assigned along the (contact surface of the pressure bar 7 to each tensioning screw 5.4 (FIGS. 3 and 6).
  • each with two tensioning screws 5.4 in total four tensioning levers 33 which are advantageously arranged in mirror image to the center of the plate cylinder 1 (FIG. 7).
  • the tensioning levers 33 are supported on the pressure bar 7 via a molded-on cam 34 with a force-intensifying lever transmission.
  • One end of each of the tension levers 33 is connected to the rear tensioning rail 5 by means of a swivel 35, i.e. the lower clamping device 5.2 connected.
  • the other free end of the tensioning lever 33 is supported on a stop pin 37 under the action of a spring 36 which is supported in a cylinder-fixed manner. This lies on the connecting line of the rotary joints 35 in the rear tensioning rail 5.
  • a gap a therefore arises between the pressure bar 7 and under the clamping device 5.2 (FIGS. 6 and 7).
  • a register correction in the circumferential direction is then carried out in a known manner via the tensioning screws 4.4, 5.4, in the axial direction by means of the adjusting screws indicated in FIG. 7, in particular in the middle of the plate cylinder 1.
