Definitions

  • the invention relates to a rotary printing press with a Folding apparatus according to the preamble of claim 1.
  • FIG. 1 An example of a known drive, for example after DE 41 27 321 A1 is shown schematically in FIG. 1.
  • the coupling from the longitudinal shaft 1.10 to the Folding apparatus comprising a knife cylinder 2, a collecting cylinder 3 and a jaw cylinder 4, mechanically a longitudinal shaft gear box 1, different tooth levels 1.20, a shaft 1.23 on a coupled with a bevel gear 1.24 Intermediate gear 1.3 or alternatively with a bevel gear 1.24 coupled knife cylinder 2.
  • the cylinders 2, 3 and 4 are mechanically coupled with each other via spur gears.
  • the disadvantage here is that the Cylinders 2, 3 and 4 to each other and to the longitudinal shaft 1.10 in the area of the backlash can take any position. The reason for this are effective on the cylinders Moments such as Curve controls or cutting stroke. Not through this avoidable irregularities are noticeable in the folding tolerances.
  • a rotary printing press with at least one folder which is equipped with at least one own drive motor mechanically independent of at least printing units the printing press is driven from EP 0 567 741 A1, DE-A 2 046 131, GB 2 149 149 A, from "Deutscher Drucker” No. 14-15 from April 13, 1995, pages w46 ff, and from "Zeitungstechnik", December 1991, pages 78-80.
  • the single drive from Finally, folding apparatus is also known from the subsequently published EP 0 699 524 A2.
  • the invention has set itself the task of flexibility in terms of Configurability of a rotary printing press, as far as cutting, folding and laying out is affected to increase.
  • the register setting should be prevented, at least at the same time Reduction of the folding inaccuracies due to the tooth play of the gears in the Drive train of the folder can be made individually for the folder can.
  • the invention relates to a rotary printing press with at least one folder, the comprises at least one knife and one jaw cylinder and by equipment with at least one own drive motor mechanically independent of at least printing units the printing press is driven and can be independently set up and registered.
  • the folder is arranged according to the invention at the roll changer level.
  • the free one is Arrangement or adjustability of the folder to the printing units and advantageously also for a fold structure and a fold superstructure without incurring additional costs, possible.
  • a first folder can be placed on the plant level, while a second folder is offset in the machine basement. As a result, short web transfer paths and unhindered access to the folders are achieved. If a fold structure and a fold superstructure are set up on the machine table, ie on the system level, the overall height is low.
  • Both folders can also be set up in the basement as a double folder with a separate structure mounted on the machine table or as a double folder in a common superstructure. Both variants stand out because of the arrangement in the reel changer level due to its low overall height above the machine level out. Furthermore, because they are arranged on one level, they are particularly easy to use.
  • the folder itself is movable. Will the fold structure and the superstructure is placed on a yoke, so a back-up folder, if such is intended to be inserted instead of the main folder if necessary.
  • a back-up folder if such is intended to be inserted instead of the main folder if necessary.
  • no additional space in the System needed. If the machine table itself is used as a yoke construction, and will be the folders in the basement, this also results in a low overall height.
  • the fold structure and the fold superstructure on a yoke construction be movably arranged.
  • the invention can be used particularly advantageously with the one disclosed in EP 0 644 048 A2 Combine drive and control concept.
  • this document teaches that a pair of a printing and a Impression cylinder of a printing unit mechanically independent of other pairs of Printing and impression cylinders of the same printing unit and one printing cylinder each from its impression cylinder or impression cylinders mechanically independent should be driven.
  • a drive motor drives via a mechanical one Coupling, preferably a motor-side pinion and a cylinder-side spur gear on the Jaw cylinder.
  • a mechanical one Coupling preferably a motor-side pinion and a cylinder-side spur gear on the Jaw cylinder.
  • Another variant is the drive motor there to arrange where, according to the prior art, the longitudinal shaft gear box sits.
  • the Drive motor via a toothed belt on the knife cylinder.
  • the mass of the knife cylinder can be low of the drive motor can be added, which increases the control dynamics can be improved.
  • This can include a translation between drive motor and knife cylinder in more than one stage.
  • the drive from the motor via a toothed belt is also preferred on the collecting cylinder.
  • the mass of the Collecting cylinder which is larger than that of the knife cylinder, be added to the low own mass of the drive motor, which, as already mentioned, improves the control dynamics. In turn can a multi-stage translation between the drive motor and Collection cylinders may be preferred.
  • Such a toothed belt can also be used on the jaw cylinder to be driven.
  • the Drive drives the drive motor to any one via a toothed belt Gear in the entire drive train between the knife cylinder and delivery, for example a paddle wheel.
  • the Drive also in operative connection with the drive train stationary idler gear. The required gear ratio from the drive motor to the gear is advantageous single-stage, so that again a space-saving solution is created.
  • a printing web B runs through a capping device 20, a pair of pulling rollers 21 arranged behind, via a Collection cylinder 3 with assigned knife cylinder 2, there cut crosswise and then from the collecting cylinder 3 to the Folding jaw cylinder 4 and from there to a delivery device serve serving paddle wheel 5.
  • the paddle wheel 5 can also be a means of transport that rotates endlessly between two rollers provided with grippers for the folded printed copies his.
  • the jaw cylinder 4 driven directly by a drive motor 10.
  • the mechanical coupling between the drive motor 10 and the The jaw cylinder 4 is driven by a pinion 10.1 and a cylinder-side spur gear 4.1 is formed.
  • a printing press is shown, which is an example for gaining flexibility in terms of installation options of the self-powered folder.
  • An exemplary embodiment is a folder F1 in the machine basement on the same level as reel changers R1, R2, R3 and R4 set up, while printing units Dl, D2 and D3 on one above horizontal plant level 100 are aligned one behind the other.
  • a folder structure or folder superstructure 30 that opens one or more levels has at least one funnel, arranged and stored on the folder.
  • the rebate superstructures 30, 40 are between the two printing units D2 and D3 arranged so that the printing webs run in from two sides.
  • a second folder can be provided.
  • This second folder is preferred also at the reel changer level or at the plant level 100, preferably approximately in alignment with the lower fold superstructure 30 arranged.
  • the printing webs can optionally be fed to one of the folders become. In the example of Fig. 3, only that is in the engine room standing folder F1 in operation. If two Folders are provided, some of which are behind the Printing units further promoted printing webs, the folding structure, as shown by dashed lines as an example. From upper funnel of the folding structure 30 reach the longitudinally folded Printing webs then to the second folder, while the in lower hopper of the folding structure 30 folded printing webs continue to be fed to the first folder F1.
  • Fig. 4 shows the installation of the second folder mentioned F2 at plant level 100.
  • the first folder is again F1 in the machine cellar, on the same level as the not shown role changers placed while the second Laying out the F2 folder on one side of the machine next to the machine is arranged.
