Definitions

  • the invention relates to a device for changing of printing forms on a printing form cylinder in the printing unit one Rotary printing machine, one on a printing unit Holding device is provided, in which both at least a printing form to be fed is included, as well as a print form to be exchanged can be accommodated.
  • EP 0 530 565 A1 discloses a magazine for the automatic Plate change.
  • the magazine for the Plate change provided multiple printing plates thereby that a cassette can be inserted into the magazine, which in turn holds several printing plates. As required these can be removed by the plate feeder.
  • EP 0 567 754 A1 shows a device for feeding a Printing plate to a plate cylinder of a printing machine.
  • This device is gentle on the printing Surface of a printing form achieved in that for holding and Guide the printing form at least one easily rotatable roller is provided.
  • the side of the roll facing the printing unit lies in a plate changing position essentially on a straight line parallel to the Clamping surfaces of the device for receiving the printing plate leading edge passes between these clamping surfaces and diagonally upwards out of the printing unit leads out.
  • a suction cup can also be provided his.
  • EP 0 570 702 A1 discloses an apparatus for feeding printing plates on the plate cylinder of printing machines, in particular sheet-fed printing machines.
  • An in a guide rail on the printing unit movable protection includes a slightly curved Sheet profile.
  • the sheet profile in turn has an insertion rail, which the Front edge of the printing form to be fed directly into the detection area of the Introduces clamping devices of the printing form cylinder.
  • JP-A-62-019458 relates to a printing plate changing device for feeding Printing plates from and to a printing form cylinder.
  • a printing plate changing device for feeding Printing plates from and to a printing form cylinder.
  • On the side walls of a Printing unit are each included rails that cover the lateral areas of the Capture printing forms and feed them to a printing form cylinder.
  • the feeding of the printing plate to the clamping devices on the printing form cylinder is carried out by the weight of the Printing plate.
  • US 5,181,466 relates to an offset printing machine, in which the blanket over an automatic feeder and a plate cylinder cover over a automatic feed device can be fed to the cylinders.
  • the blanket over an automatic feeder and a plate cylinder cover over a automatic feed device can be fed to the cylinders.
  • the disclosed solution can only have one plate cylinder cover in each Feeder can be included.
  • the invention is therefore based on the object of a device for changing the printing form to improve so that seen across the printing unit width when operating the printing unit as few parts as possible remain in the access area of the printer, so that the printing unit remains accessible as freely as possible.
  • the advantages achievable with the solution according to the invention are, among other things, that the printing surfaces of the Printing forms are not touched.
  • the management of the printing forms in the laterally arranged profile bodies ensures that after lifting the printing form to the extent of the Printing forme cylinder no longer has a component in the work area respective printing unit remains.
  • the printer now has unimpeded access to the printing unit - for cleaning and if necessary for maintenance work.
  • the profile body both stationary on the side walls of the Printing unit as well as pivotable on the side walls be included.
  • the profile bodies are advantageous each provided with recesses through which the Side areas of the printing forms are included and thus serve as a guide.
  • the recesses can be in the Profile bodies meandering - preferably S-shaped, so that each of the printing forms to be included stiffening deformation is imprinted against it Vibrations on the printing unit less sensitive and through which enables lateral guidance in the recesses becomes.
  • the profile body also include drive units, namely each for the first printing form to be fed, as for the taking second printing form.
  • the drive units For example with compact electric motors Friction rollers - work together with support elements, so that the side areas on both sides of the printing forms can be promoted frictionally.
  • the mentioned Supporting elements can be in the form of rolls or ribbon-like be executed. In the area of the drive units at the respective recesses on the profile body Side areas led.
  • 1 is that according to the invention Solution on an upper printing form cylinder 3 one Printing unit 1 shown. With a lane on both sides printing device, the device according to the invention easily at the bottom of the printing form cylinder be provided.
  • each Profile body 9 On the two side walls 2 of a printing unit 1 are each Profile body 9 attached.
  • the printing forms 4 and 5 each have printing form leading edges 7 and Printing form trailing edges 8 on, in clamping devices the scope of the printing form cylinder 3 are introduced and the Printing forms 4 and 5 on the circumference of the printing form cylinder 3 fix.
  • the side areas 6 (see FIG. 2) of the printing forms are in profiles 10, 11 on or within the Profile body 9 out.
  • the profiles 10, 11 for receiving the Side areas 6 of the printing forms 4, 5 are as Recesses 12, 13 executed, which are curved in a meandering shape or run within the profile body 9.
  • the recesses Preferably have an S-shaped curvature.
  • Means the printing plates 4 and 5 through the recesses 12, 13th imprinted curvature, the printing forms 4, 5 are such stiffens that their guidance only on the side areas 6 is completely sufficient. Therefore, they are not guides necessary on the printing surface of the printing plates 4 and 5 act, reducing the risk of damage to the sensitive surfaces is drastically reduced.
  • Drive units 14 are provided on the profiles 10, 11 of the profile body 9 . These drive units 14 work together with support elements 15 which in Embodiment are shown as roles. Tapes or Plastic chains would also be conceivable.
  • the drives 14 include the friction rollers 14.1.
  • the friction rollers 14.1 work with Support elements 15 together, which are below the Friction roller 14.1 are provided.
  • the friction roller 14.1 and the support element 15 grip the side region 6 of the Printing form 4 on both sides and promote the printing form 4 on the Scope of the printing form cylinder, not shown here 3.
  • Um proper transport of the printing forms 4, 5 - that is to be fed as well as the printing form to be removed ensure, the drive unit 14 shown is a corresponding on the opposite - not shown here Associated side wall 2 of the printing unit.
  • Each extending into the profile body 9 Recess 12, 13 is at least one drive unit 14 assigned.
  • the Drive units 14 shown in FIG. 2 are located also along the funding path for the second one, too removing printing form 5, even if not in Fig. 2 is shown.
  • Friction rollers 14.1 which are connected to the support element 15 interact, the areas 6 of the Printing forms 4, 5 approximately in the center of the cross section of the Recesses 12, 13 lead so that grinding on the Surfaces of the recesses 12, 13 can be effectively prevented can.
