Definitions

  • the invention relates to a rotary printing machine, and in particular a rotary printing machine, which can still be installed in a particularly space-saving manner at its respective installation site with high printing capacity and high system flexibility.
  • this constant need is based on the fact that in larger printing presses, especially higher-heeled printing presses, more workers are needed to operate the system, which can significantly increase labor costs. Therefore, the operators of printing systems strive to procure compact systems that are to operate with the least possible personnel costs.
  • a conventional printing unit as used in such a stunted rotary printing presses, for example, is the H-pressure unit with an 8-cylinder system (rubber-rubber) used by MAN Roland AG in their "CROMOMAN” printing press.
  • the "CROMOMAN” two such H-printing units are stacked or stacked to a printing tower, whereby for high color and page capacity in a small space, for example, a so-called 4/4-color printing (the application of four colors on each side of a In this configuration, the paper web is passed substantially vertically through the printing units, each printing unit having four printing locations or printing units, ie two for each web page.
  • the newly developed printing units which now incorporate more pressure points, have a higher weight than conventional printing units. Since in rotary printing presses, such as the "CROMOMAN", each upper printing unit is placed directly on the respective lower printing unit, the entire weight of the upper printing unit rests on the lower printing unit. If the weight of the printing units now increases, this can, for example, lead to unwanted deformations on the lower printing unit.
  • such plant configurations are generally limited in that the printing units stacked on top of each other should, if possible, have the same width and depth dimensions to allow such stacking.
  • this arrangement can For example, the printing units transmit vibrations of one printing unit of the printing tower to the other printing unit of the printing tower.
  • the object of the invention is to provide a rotary printing press in which printing units arranged one above another are physically decoupled from one another such that unwanted interactions between the printing units are reliably avoided.
  • a rotary printing press comprises a printing tower having a first printing unit arranged on a support base and a second printing unit arranged above the first printing unit and a substructure supporting the second printing unit so that the weight of the second printing unit Pressure unit on the substructure assembly loads.
  • such a plant configuration offers the advantage that, as the weight of the upper pressure unit rests on the substructure, the lower pressure unit is not exposed to excessive stresses which could lead to deformations on the pressure unit.
  • deformations may, for example, be deformations of the bearing seats or of the bearings for the cylinders or rollers of the printing unit.
  • the two printing units are vibrationally decoupled from each other, whereby the bearings of the printing units are spared and the print quality is improved.
  • the substructure has a horizontal section and a vertical section.
  • This embodiment of the substructure is robust and can be easily integrated into the printing press.
  • the vertical section has upper ends and lower ends
  • the horizontal section has lateral ends which are supported at the upper ends of the vertical section.
  • the lower ends of the vertical portion are supported on the support base.
  • the horizontal section extends between the first printing unit and the second printing unit.
  • This embodiment can be realized, for example, as a continuous or interrupted portal construction or as a self-supporting construction using, for example, steel beams and / or concrete elements, wherein the horizontal section is fastened or supported on the vertical section. This is inexpensive and easily integrated into the printing press.
  • the horizontal portion has an upper surface on which the second printing unit is arranged.
  • This embodiment is advantageous in that the upper pressure unit is mounted in the same way as the lower pressure unit, namely standing on its underside, so that no additional fastening means or structural changes to the upper pressure unit must be provided in comparison to the lower pressure unit in order to set this up ,
  • the horizontal section between its lateral ends on a width dimension which is at least as large as a width dimension of the first printing unit and extends substantially parallel thereto.
  • This embodiment ensures a secure state of the upper printing unit and a correct alignment of this to the lower printing unit of the printing tower. Further, if the width dimension of the horizontal portion is e.g. is larger than that of the lower printing unit, the upper and second printing units have a larger width dimension than the lower and first printing units, respectively. This gives increased flexibility in the system configuration.
  • the vertical section between its lower and upper ends has a height dimension which is at least as large as a height dimension of the first printing unit and extends substantially parallel thereto.
  • This refinement has the advantage that the substructure arrangement can be realized on the one hand with minimal dimensions and on the other hand if the height dimension of the vertical section is greater than the height dimension of the first section Pressure unit is, if necessary, space between two printing units can be created.
  • the vertical portion has at least two vertical elements, each having an upper end and a lower end, wherein at the upper ends of the vertical elements, the lateral ends of the horizontal portion are supported.
  • This portal-like configuration of the substructure is simple, robust and inexpensive.
  • the first printing unit is arranged between the at least two vertical elements.
  • This embodiment offers the advantage that, if several such printing towers are arranged side by side, a modular structure of the individual printing towers is ensured so that printing towers can be added or omitted as needed or customized.
  • the horizontal portion has two elongated, alongside each other spaced apart support elements each having two longitudinal ends, wherein the two longitudinal ends of the support elements are respectively supported at the upper ends of the vertical portion.
  • This embodiment has the advantages that on the one hand, the upper pressure unit can be supported to save material and on the other hand space between the support elements is available, which can be used for design and technological purposes.
  • the printing units each have at least one pressure point, at least two pressure points or eight pressure points.
  • the vertical elements are integrated into two opposite side walls of the first printing unit.
  • This embodiment has the advantage that the substructure can be integrated in a particularly space-saving and material-saving in the printing press, which costs are saved.
  • the vertical elements are formed by two opposite side walls of the first printing unit, wherein axes of rotation of the cylinders of the first printing unit extend substantially parallel to these side walls.
  • the vertical elements are formed by those side walls of the first printing unit which do not receive bearings for the cylinders, such as blanket cylinders, impression cylinders and inking cylinders, of the first printing unit.
  • This embodiment additionally saves material and costs, nevertheless ensuring that the side walls of the first printing unit which receive the bearings for the cylinders are completely free of any pressure loads by the second printing unit.
