Definitions

  • the invention relates to a printing unit consisting of two nine-cylinder satellite arrangements with an approximately vertically fed, then guided on a satellite cylinder, successively passing the pressure points with a first, second, third and fourth transfer cylinder and then guided on a further satellite cylinder, successively the pressure points with a fifth, sixth, seventh and eighth transfer cylinder passing and then approximately vertically discharged substrate web, wherein a form cylinder is arranged on each transfer cylinder.
  • a printing unit consisting of nine-cylinder satellite arrangements is known in which the four each having a form and a transfer cylinder containing printing units, which are employed on a satellite cylinder having. Furthermore, in this document, two nine-cylinder satellite printing units are shown, which are arranged one above the other in a standing construction.
  • a substrate web is first printed on one side in 4-color in the lower printing unit and then fed to the upper printing unit, where the printing substrate in reverse printing also 4-sided and 4-color is printed.
  • the supply and removal of the printing material web to or from the satellite cylinder takes place in such a way that the web partially wraps around the respective transfer cylinder placed at the inlet or outlet and located in the printing shutoff.
  • the inventors have set themselves the task of further improving such a printing unit.
  • the inventors have recognized that it is beneficial for both the placement of the washing cylinders for the transfer cylinders, the washing devices for the satellite cylinders and the placement of the plate changing devices when more space is created between the transfer cylinders arranged around the satellite cylinder. This space can be created by the fact that the satellite grows in circumference and thus also increases the distances between the subsequent transfer cylinder to this.
  • the inventors have further recognized that in printing units in which the forme cylinders each carry only one printing plate relative to the circumference of the forme cylinder, but optionally a plurality of printing plates in the width of the forme cylinder side by side, and with a cylinder to cylinder ratio of 1: 3 in circumference, there is sufficient space between the transfer cylinders adjoining the satellite cylinders, and at the same time the driveability is controllable due to the growing satellite cylinder mass.
  • the inventors propose a printing unit consisting of two nine-cylinder satellite arrangements with an approximately vertically fed, then guided on a satellite cylinder, successively passing the pressure points with a first, second, third and fourth transfer cylinder and then on a further satellite cylinder guided, successively passing the printing locations with a fifth, sixth, seventh and eighth transfer cylinder and then approximately vertically discharged printing substrate, wherein a cylinder is arranged on each transfer cylinder to improve in that the ratio of the sizes of forme cylinder to satellite cylinder 1 to 3 is.
  • the ratio of the sizes of forme cylinder to transfer cylinder may be either 1 to 1, 1 to 2 or 1 to 3.
  • a quadruple-sized satellite cylinder has also proved to be favorable.
  • the ratio of the sizes of forme cylinder to transfer cylinder to satellite cylinder is then 1 to 2 to 4 in this embodiment.
  • the inventors expressly point out that the indication of the circumferential ratios of the cylinders are not to be evaluated mathematically exactly, for example as ratios of exactly millimeter specifications, but that even slight tolerances, which result from the variation in circumference by clamped or unclamped printing plates or blankets are also included.
  • a circumference ratio of forme cylinder to transfer cylinder to satellite cylinder is from 450 mm (+/- 2 mm) to 900 mm (+/- 10 mm) to 1800 mm (+/- 2 mm) as a circumference ratio of 1 to 2 to 4 in the sense understood the invention, although mathematically speaking does not add exactly 1 to 2 to 4 with the addition of tolerance information.
  • the circumference of the forme cylinder is between 400 mm and 700 mm, preferably between 450 mm and 600 mm.
  • the resulting masses of the transmission and satellite cylinders and the associated necessary for driving and deceleration drive components can be realized without much effort.
  • At least one pressure plate is arranged on the forme cylinder.
  • one or two or three or four or five or six or seven or eight printing plates may be arranged side by side.
  • exactly one or two or three or four or five or six or seven or eight pages of a printed product can be imaged on a printing plate.
  • the number of pages can increase up to 16.
  • the one to eight pages can either be displayed in broadsheet format, or the two to sixteen pages in tabloid format or in panorama format on the printing plate. But also a combination of the three types of formats on a printing plate is proposed by the inventors.
  • a satellite washing device is arranged between the incoming and outgoing printing material web and / or at its opposite side on the satellite cylinder.
  • the arranged between the fed and discharged printing substrate satellite washing device allows cleaning of the print tray, which comes from the page just printed on the satellite cylinder, while the other side of the substrate is being printed.
  • a blanket washing device should be arranged in each case.
  • two transfer cylinders can be cleaned in pairs.
  • a blanket washing device can be arranged on all four transfer cylinders.
  • the blanket washing devices wherein two pairs or even four can be individually adjusted to the transfer cylinder, are present in a symmetrical manner to the second nine-cylinder satellite accordingly.
  • the nine-cylinder satellite arrangements can operate either by the offset printing method or by the indirect gravure printing method. For this purpose, an adjustment of the inking units is made to the respective printing process.
  • the printing unit and its cylinders are four, five, six, seven or eight pages wide.
  • the cylinders can have shafts made of CFRP (carbon fiber reinforced plastic) or GRP (glass fiber reinforced plastic), which already have low bending properties due to the material. Cylinder jackets made of metal can then be applied around these shafts.

  • the satellite cylinder 13, 14 can either maintain the print image order grow four, six or another integer multiple of the circumference of the forme cylinder 11.3 to 11.10.
  • FIG. 2 shows a side view of another cylinder pair with satellite cylinders 13, 14 with a different circumference ratio of the cylinders, as proposed by the inventors.
  • the ratio of the circumferences between form 11.3 to 11.10, transmission 12.3 to 12.10 and satellite cylinder 13, 14 is here 1 to 2 to 3.
  • the direction of rotation of the cylinder is also indicated by arrows 28.
  • the cylinder arrangement of Figure 1 of the forme cylinder carries 11.3 to 11.10 only a pressure plate 11.1 relative to the circumference of the forme cylinder 11.3 to 11.10.
  • this peripheral ratio of the cylinders sufficient space is created between adjacent transfer cylinders 12.3 to 12.10 in a nine-cylinder satellite arrangement, so that, for example, washing devices or plate changing devices can be easily placed therebetween.
  • the only one printing plate 11.1 supporting form cylinder 11.3 to 11.10 allows a simple print image sequence on the transmission 12.3 to 12.10 and the satellite cylinder 13, 14th

In this designation, the number after the dot indicates the position number of the associated printing unit.
  • Each nine-cylinder satellite arrangement 1, 2 has a satellite cylinder 13, 14, with which the associated printing units 3 to 6 and 7 to 10 cooperate and form pressure points.
  • the first 12.3 and second 12.4, third 12.5 and fourth 12.6 transfer cylinders are arranged at a smaller distance from each other on the satellite cylinder 13. As a result, a large free peripheral area of the satellite cylinder 13 is created between the first 12.3 and the fourth 12.6 transfer cylinder. In this area, a printing substrate 15 in the direction of the arrow to the nine-cylinder satellite 1 and discharged. In this case, the supplied substrate web 15 is guided via a guide roller 16 and the discharged printing substrate 15 via a guide roller 17. The guide roller 16 is placed so that the substrate web 15, the nearest first transfer cylinder 12.3, in whose area it is guided, does not touch when it is in the print off. The print-off of the first transfer cylinder 12.3 is shown in dashed lines.
