Definitions

  • the invention relates to a rotary printing press, preferably for label printing with printing units of different printing processes arranged concentrically around two or more impression cylinders.
  • central impression cylinders for the arrangement of a large number of printing units around the circumference of the impression cylinder have not only the advantage of a compact design compared to known, successively arranged printing units, each with an impression cylinder assigned to the printing unit, but above all in the case of stretch-critical substrates that the substrate during processing by a plurality of printing units arranged one after the other around the impression cylinder constantly rests on the impression cylinder. It is thereby achieved that no additional control devices, which are predominantly electronically controlled today, are regularly required for checking the registration accuracy.
  • Central impression cylinders with concentrically arranged printing units have the disadvantage compared to horizontally or vertically arranged printing units, each with an impression cylinder, that the number of printing units arranged on the circumference of the impression cylinder is limited by the necessary restriction of the diameter and thus the circumference of the impression cylinder.
  • the necessary roundness of the cylinder is no longer manageable in terms of cost.
  • Another disadvantage of a central impression cylinder is that only printing processes can be used which correspond to the surface of the impression cylinder.
  • the object of the invention is to find a solution while preserving the advantages of central impression cylinders, which not only allows the arrangement of an increased number of printing units compared to conventional solutions, but also allows the use of several printing methods by several printing units.
  • two or more impression cylinders are used, which are arranged on an axle mounted on one side.
  • Printing units of a known type are arranged in parallel planes with the impression cylinders.
  • a web offset device is arranged after the last printing unit of the first impression cylinder in the direction of web travel, through which the web is guided from the first to the second impression cylinder.
  • the arrangement according to the invention of two or more impression cylinders on one axis initially has the advantage that, compared to known rotary printing presses with only one impression cylinder, the diameter of the impression cylinders is limited to a manageable level and the number of printing units arranged around the respective impression cylinder and the associated drying devices can be reduced . If up to six printing units are arranged around an impression cylinder in known rotary printing presses, the number of printing units per impression cylinder can be limited to two to four in the arrangement according to the invention. This not only has the advantage that the web run-up path on the impression cylinder can be extended so that the web on the impression cylinder has stabilized before it reaches the first printing unit, but also the further advantage that the distance between the individual printing units can be enlarged. This not only optimizes the ink drying required after each printing unit. Less large-sized and thus energy-saving drying devices can also be used.
  • the arrangement according to the invention also has the advantage that different printing methods such as flexographic printing and letterpress, which require a soft or hard impression cylinder surface, can be used in which the impression cylinders are provided with jacket surfaces of different hardness corresponding to the printing method used.
  • the peripheral speed of one impression cylinder can be increased by means of a superposition gear.
  • impression cylinders can also be driven by separate individual drives.
  • counter-pressure cylinders which are provided with a detachable tubular steel sleeve, which in turn have a surface adapted to a specific printing process.
  • Such sleeves are preferably attached to the impression cylinder by means of an oil pressure compound.
  • the web transfer device consists of two fixed rods which are arranged at a specific angle to the web direction and at a specific distance from one another and are arranged parallel to one another, the angle for the parallel web transfer being 45 ° and the distance corresponding to the web width or the width of the impression cylinder jacket.
  • FIGS. 1 to 3 To further explain the invention, reference is made to an exemplary embodiment of the invention shown in FIGS. 1 to 3.
  • the rotary printing press 1 consists of a housing 4 containing the necessary drives and units, on the front side of which two counter-pressure cylinders 2 and 3 are arranged in the center and parallel to one another.
  • the impression cylinders 2, 3, four printing units 5 and 6 are arranged in two parallel planes, as well as a drying unit (not shown) after each printing unit.
  • the web transfer device 9 shown in FIG. 2 and arranged on the lower circumference of the impression cylinders 2, 3 consists of two round bars 10 which are displaceably mounted on the housing 4 of the rotary printing press 1 and whose spacing from one another and their angle to the impression cylinders 2, 3 are adjustable.
  • the sleeve 11 shown in FIG. 3 consists of a steel tube which can be pushed onto the impression cylinder 2 and whose surface 12 consists of a rubber blanket.
  • a corresponding sleeve 11 with a hard surface is located on the impression cylinder 3.
  • the diameter of both impression cylinders 2, 3 is the same. Deformations of the steel tube 11 covered with a rubber blanket during printing, which can be up to 5/100 mm, make it necessary to drive the rubber blanket impression cylinder 2 minimally faster than the impression cylinder 3, which is due to the joint drive of the impression cylinder 2 , 3 acting superposition gear, not shown, is reached.
  • the web to be printed is fed to the impression cylinder 2 via a pressure roller 7, fed to the impression cylinder 3 after circulation via the web transfer device 9 and, after its circulation, discharged via the roller 8 for further processing with devices not shown.
