Definitions

  • the invention relates to a rotary printing machine and further to a printing unit and a folding apparatus in or for a rotary printing press, preferably web-fed rotary printing press.
  • the printing unit may in particular be an offset printing unit, for example for dry offset or preferably for wet offset.
  • the printing unit or folder is intended for newspaper printing.
  • Printing components of rotary printing presses for example printing column-forming printing cylinders, associated printing cylinders and associated rollers of inking or dampening units, are usually stored individually in side frames.
  • the exact, in particular positionally accurate production of the bearings requires a lot of effort in the processing of the side frames.
  • mechanisms for the adjustment of the pressure components are required. All this drives up the cost of the printing press.
  • One approach to reducing costs is to increase the number of units through modularity, ie by using components that can be used in different printing presses. This is what the DE 10 2004 063 944 A1 and the DE 199 37 806 B4 each storage of pressure components in storage modules.
  • the complexity of the storage is transferred to the storage modules, which are connected in a relatively simple way with the respective side frame.
  • the storage modules are designed as carriages, which are guided linearly on the side frame to make the pressure components together and to be able to park each other.
  • Each carriage is assigned its own intervention structure.
  • the slides are each equipped with an engaging member that is in threaded engagement with the respective associated engaging structure.
  • the Eingriffs Designn are each driven by a separate motor for the on and off of the pressure components.
  • the invention relates to a printing unit comprising a plurality of printing components, namely a first printing cylinder and a second printing cylinder, which together form a printing gap for a web to be printed, and also at least one inking unit component for transferring ink to the first printing cylinder.
  • the inking unit component can transfer the ink directly or preferably via a forme cylinder to the first printing cylinder.
  • the printing unit also includes the form cylinder as a further printing component.
  • the forme cylinder is optional, as is one or more dampener components for a preferred wet offset pressure.
  • the term "printing components" is understood to mean those components which transmit or deliver the printed image to the web-producing ink or moisture during the printing operation of a rotary printing press.
  • the inking unit component can be an inking roller and the optional dampening unit component can be a dampening roller.
  • the components in question may also be colorimeter bars, wet bars, paint pump bars or trusses for receiving other elements for applying or transferring color or moisture.
  • the printing unit also comprises a side frame on at least one end face of the printing components, furthermore a first slide and at least one second slide.
  • the first carriage forms a bearing for at least one of the pressure components, hereinafter referred to as first pressure component, and has an engagement member.
  • the second carriage forms a bearing for at least one other of the pressure components, hereinafter second pressure component, and is equipped with a second engagement member.
  • an engagement structure extending transversely to the axes of rotation of the impression cylinders and a guide for the slides parallel to the engagement structure are arranged. If the engagement structure is a spindle as preferred, then each of the engagement members is a threaded member. Alternatively, the engagement structure may for example also be a rack.
  • gears form the engagement members.
  • the bearings formed by the carriage can be fixed bearings, in particular for the attachment of a traverse carrying paint or dampening components.
  • the sled can also for a cylinder or a roller of the printing unit a fixed bearing, ie form a fixed clamping, wherein a required for the cylinder or the roller roller bearing is elsewhere, but with the carriage movable created.
  • a cylinder or roll shell could be provided which is rotatably mounted on an axis non-rotatably connected to the carriage.
  • the engagement structure with the engagement members of both carriages is each engaged, which in the case of a rotational relative movement between one of the engagement members and the engagement structure causes a translational relative movement between the respective engagement member and the engagement structure.
  • both carriages are in guide engagement with the guide in which the carriages are linearly guided along the engagement structure and are prevented from rotating relative to the engagement structure. Relative rotation between the engagement members on the one hand and the engagement structure on the other hand thus generates movement of the carriages and the pressure component or components supported by the respective carriage along the engagement structure and the guide.
  • the limitation given in such solutions in the length of the adjustment omitted.
  • This increases the flexibility in terms of configurability, since the length of the engagement structure and the guide and thus the side frame no longer have to be adapted to a specific configuration of cylinders and ink or dampening components. It opens up scope for variations.
  • the same side frame can be used to form printing units whose printing components differ in their dimensions measured transversely to the axes of rotation of the printing cylinders in order to be able to print, for example, two different newspaper formats with the two printing units different in this respect.
  • the engagement structure can receive the force exerted on each other along the engagement structure guided cylinders or rollers, which form a pressure nip or a nip for the transfer of color or moisture. As a result, a weight of the pressure components bearing side wall of the side frame is relieved.
  • the external rotor drive As a rotary drive for one, several or all the pressure components that are rotationally driven about their respective axis of rotation, the external rotor drive is suitable.
  • a preferred external rotor drive is in the PCT / EP2004 / 013784 described.
  • at least one stator winding is provided so that when current flows through the stator winding in interaction with the at least one permanent magnet of the rotor, a torque acting on the rotor is generated, by which the rotor is set in rotational motion can be.
  • the rotor may in particular form a cylinder or roll shell.
  • An external-rotor drive with an electric motor which is integrated completely or at least partially into the rotor, has, inter alia, the advantage that no installation space is required for the rotary drive of pressure components in the area of the carriages.
  • the respective pressure component is autonomous with respect to its rotary drive, so to speak.
  • a drive means for a rotary drive of the engagement members preferably only the engagement members, or the engagement structure, in this case preferably only the engagement structure
  • the drive means is formed in a preferred embodiment for a single drive of the engagement members.
  • the drive device preferably has, for each carriage, its own motor, which drives only the engagement member or possibly a plurality of engagement members of the carriage.
  • the motors can each be arranged in a housing of the respective associated carriage or on the outside of the respective carriage.
  • the engagement structure advantageously has axial sections with different thread pitches.
  • the respective threaded portions may differ from each other in terms of the sense of rotation, a first threaded portion so a left-hand thread and another threaded portion be a right-hand thread.
  • the threaded sections can also have the same direction of rotation and differ from each other only in relation to the steepness of the respective thread.
  • the threaded portions can be separated from each other both in terms of the sense of rotation and in relation to the steepness be different.
  • a spindle with one or more left-hand threads and one or more right-hand threads can serve, for example, for the adjustment of the impression cylinders in order to be able to reverse the impression cylinders between pressure on and pressure off.
  • the respective other printing components associated with the respective printing cylinder for example one respective forme cylinder and one or more inking unit components, would be co-adjusted in accordance with the adjustment of the respective printing cylinder.
  • the engagement members of these further pressure components may be threadedly engaged with a threaded portion of the engagement structure having the same sense of rotation as the threaded portion for the carriage of the impression cylinder of the same printing unit but a different pitch.
  • the relative rotational movement can also be due to superposition of an absolute rotational movement of one or more engagement members and the engagement structure.
  • the engagement structure or guide advantageously extends to the end of the side frame, or at least to near the end, so that the carriages and correspondingly the pressure components carried by the carriages at the end of the side frame or at least close to the end of Side frame can be driven. This is especially for maintenance and repair work, as well as for the assembly of the printing unit advantage. If the engagement structure or guide extends or extends to the end of the side frame, the slides can be moved from the so-called open end of the side frame very easily upon assembly of the printing unit into its intended for later printing operations positions. Extends or extend the engagement structure or the guide only to near the end of the side frame, this at least facilitates the inevitable maintenance and repair work, since the pressure components can then be moved apart than before.
  • the engagement structure or guide extends in preferred embodiments over a length sufficient to cover all or at least a majority of the pressure components associated with the first impression cylinder along the engagement structure or to order the leadership. If the second printing cylinder in mirror image or other arrangement just such other pressure components such as a forme cylinder and one or more inking unit (s) and optionally associated with one or more dampening component (s), this means that the engagement structure for the first printing cylinder over at least about half the width of the printing unit extends. In further developments, the second impression cylinder is also moved transversely to its axis of rotation by means of the same engagement structure and the same guide.
  • the impression cylinders form the first and second pressure components.
  • first printing cylinder is associated with a forme cylinder, preferably a further, third carriage forms a bearing for this forme cylinder.

  • This carriage is also provided with an engagement member which is in threaded engagement with an engagement structure, preferably again the same engagement structure.
  • the carriage or carriages for the optionally one or the optionally two forme cylinders is or are preferably provided with the same guide in a rotationally secured guiding engagement as the carriages for the printing cylinders.

  • the second impression cylinder may be transversely movable along the same engagement structure and guide as the first impression cylinder and its form cylinder.
  • the engagement structure may have the same thread throughout if the carriages of said lateral movement pressure components are individually driven.

  • the inking unit component or the dampening unit component can be arranged to be movable transversely along the same engagement structure and guide on the side frame. It can also be the inking unit and the Dampening component along the same engagement structure and guide on the side frame to be arranged transversely movable.
