Definitions

  • the invention relates to a device for register-oriented alignment of a plurality of printing plates arranged side by side in the axial direction on a plate cylinder of a rotary printing press according to the preamble of patent claim 1.
  • each printing plate has trapezoidal stop pieces which are fixed laterally in the clamping channel and are designed as clamping bushes.
  • the disadvantage of this solution is that two stop pieces must be provided laterally for each pressure plate in the clamping channel, which require a certain width of the channel.
  • the channel causes the plate cylinder to run out of round as a result of channel runout, which in turn leads to register errors.
  • the generic DE-PS 35 45 297 shows an adjustable side register for printing plate cylinders of a rotary printing press.
  • Bent plate ends have recesses which engage in register pins or register plates in the cylinder pit.
  • These register pins are connected, for example, to telescopically interlocking actuators which can be actuated from the cylinder face of the plate cylinder.
  • the adjusting pieces each have an internal and external thread of different dimensions and pitch, the pitch of the threaded pieces assigned to the register plates increasing towards the outside, so that the outer pressure plate is displaced to a greater extent than the inner plate facing the cylinder center.
  • the actuating elements are actuated by a common adjusting screw, which also has an internal and external thread of different dimensions and pitch.
  • the disadvantage of this solution is that the printing plates arranged up to the center of the plate cylinder can only be adjusted together, ie it is assumed that the paper web is always in relation to the different dimensions and pitches of the threads of the adjusting pieces during printing changed, for example expanded.
  • the expansion of the paper webs can, however, be different and depends on the paper quality and the dampening solution management of the printing plates.
  • the side actuating device mentioned has a relatively large amount of play.
  • the register plates located near the center of the cylinder also have a lot of play due to the lack of storage of the telescopically arranged adjusting pieces.
  • Each clamping rail has register bolts that do not point into the interior of the cylinder pit.
  • the clamping rails are axially connected to each other by means of double threaded bolts and can thus be moved against each other in order to bring the clamped pressure plate into the desired side register.
  • the clamping rails are not cylinder insert strips because their upper surface is not adapted to the curvature of the cylinder jacket.
  • the invention has for its object to provide a device for registering printing plates on plate cylinders of rotary printing presses, the printing plate beginnings are angled greater than 90 ° and are located in a narrow cylinder channel.
  • the advantages of the solution according to the invention consist in particular in that the devices for guiding the printing plates can be individually displaced in the axial direction and are therefore adjustable, so that the expansion of the paper webs can be taken into account in accordance with the different dampening solution guides. Locking the insert strips with screws ensures that there is no play.
  • the device according to the invention can also be used in plate cylinders which are guided through bearer rings. Due to the arrangement of a cylinder pit and the use of insert strips located therein, complex precision bores are eliminated and repair or maintenance work can be carried out without the plate cylinder having to be removed from the machine frame.
  • the insert strips in the cylinder pit reduce the channel for receiving the bent ends of the pressure plates to a minimum, ie two pressure plate thicknesses, so that channel strikes are excluded.
  • a partial front view of a plate cylinder 1 with a journal 10 is shown, which carries eight pressure plates, of which the pressure plates 2 to 7 are shown.
  • the pressure plates 5 to 7 are only hinted at. 2 and 3, the plate cylinder 1 has on the cylinder circumference an axially extending cylinder pit 8.
  • This cylinder pit 8 is easily manufactured by milling.
  • Insert strips 14 to 17 are fastened in the cylinder pit 8 by means of screws 9 and 11 to 13. The screw for fastening the insert bar 14 is not shown.
  • the screws 9 and 11 to 13 are received by threaded bores which run from a shoulder 19 of the cylinder groove 8 in the radial direction.
  • the insert strips 15 to 17 each have a register pin 21; 22, which with a slot 25; 30 each Pressure plates 2 to 7 are connected.
  • the register pin 21; 22 are preferably made of hard metal and can be glued to the insert strips 15 to 17. According to FIG. 3, the pressure plates 3; 6 added.
  • the channel 23 is so narrow that just the angled pressure plates are accommodated at the ends.
  • the insert strips 14 to 17 have, according to FIGS. 1 and 2, axial bores 24 which each have differential screws 26; Record 27.
  • the differential screw 26 has a hexagon socket 28 for actuation from the end face of the plate cylinder 1 and has two threaded parts 29; 31 on.
  • the threaded part 29 consists for example of a thread M8 x 1.25 and the threaded part 31 can consist of a thread M6 x 1.
  • the differential screw 27 has threaded parts 32; 33, which are also dimensioned differently, for example M6 x 1 and M6 x 0.75.
  • the threaded parts 29 and 31 to 33 correspond to corresponding threaded bores in the insert strips 14 to 17.
  • a vernier 34 to 37 is provided for each side register adjustment, with part of the scale in each case on the plate cylinder 1 and the other part of the scale on the insert strips 14 to 17 is located.
  • the screws 9; 11 loosened and the differential screw 28 is actuated.
  • the change can be read on the vernier 34, whereby the scales can have a division of 99: 100.
  • the screws 9; 11 again tightened.
  • the screws for the insert bar 17, which are not shown in FIG. 1 are loosened and by actuating the external hexagon 38 connected to the differential screw 27, the insert bar 17 is actuated with the register pins and thus the pressure plate 7.
  • the screws for fastening the insert strip 17 are tightened again after the required adjustment on the vernier 37 has been checked.
