Definitions

  • the invention relates to a method for operating a printing machine system according to the preamble of patent claim 1.
  • Each production for example a newspaper printing batch, requires different ways from a roll changer via one or more printing units to a former.
  • This current production-specific path is defined in the control device of the printing press system as a web path.
  • pamphlet EP 1 223 034 A2 shows a synchronous control device for a printing machine, wherein a master control section generates any commands for various printing units, and transmitted to the printing units slave control sections for execution.
  • pamphlet DE 43 18 299 A1 shows a retractor for feeding a plurality of printing material webs, which are fed at different times due to different lengths of the printing material webs.
  • pamphlet DE 44 35 429 A1 shows an adjustable reel changer for receiving substrate webs with different widths.
  • the present invention is based on the problem to change the control of a printing press system so that different pathways act differently from each other.
  • this new method to run several functions, for example, in the process of paper feeding, accessing multiple functional elements of the printing press, simultaneously or arbitrarily offset in time.
  • This simultaneous or staggered running allows several work steps, such as, for example, the assembly of the printing press or the actual printing process to run parallel next to each other.
  • set-up time, especially when feeding paper can be shortened, paper waste can be minimized and, at the same time, the capacity utilization and production efficiency of a printing press system can be optimized.
  • the functional units of different web paths can be operated at different speeds.
  • the paper with the paper pickup at about 50 meters / minute automatically fed from the second reel splitter to turning days and the turning part of the first roll changer from the turnaround to the funnel with a lower speed for safety reasons of about 5 meters / minute manually be confiscated.
  • the functional units of different railways can be started at different times.
  • different operating or operating states of the printing press can be treated separately from one another, or run separately from one another.
  • the printing presses which usually run at the same speed so far, for example the synchronization of the synchronized printing units or their cylinders, a more individual application of the printing machine is thus possible.
  • the new method makes it possible to stop the functional units of different track paths at different times.
  • a paper web can be pulled up to the former, while the other paper webs are stopped before or after the turning days (s).
  • the aforementioned paper jam or web break in the region of the former inlet can be avoided thereby.
  • a favorable variant of the new method envisages jointly controlling the drives belonging to a particular railway path.
  • the synchronization of the drive motors and a uniform speed of the paper web on this path is thereby ensured easier.
  • Each printing unit of an offset printing machine has at least one printing plate cylinder and a blanket cylinder. Thanks to the new process, the cleaning processes in the various printing units can be started individually and be stopped, regardless of paper feeding on other printing units of the same printing system.
  • FIG. 1 shows a schematic representation of the individual feeder of six paper webs 3.1 to 3.6 in a newspaper printing machine 6.
  • all the paper webs 3.1 to 3.6 each of a reel changer 1 via a printing unit 2 to the folding unit 5 are fed.
  • the paper webs 3.1 to 3.4 are pulled over the left turning unit 4.1, which has four turning days, to the folding unit 5.
  • the paper webs 3.5 and 3.6 are drawn to the folding unit 5 via the right-hand turning unit 4.2, which has two turning floors.
  • the single feeder are, as the name suggests, the paper webs 3.1 to 3.6 individually retracted one after the other.
  • FIG. 1 shows a schematic representation of the individual feeder of six paper webs 3.1 to 3.6 in a newspaper printing machine 6.
  • the fourth paper web 3.4 was first fed to the folding unit 5 and the other paper webs 3.1-3.3, 3.5 and 3.6 are then pulled individually in succession to the folding unit 5.
  • This known type of paper equipment for preparing the printing is unfavorable both in terms of paper waste and the duration of the Einziehvorgangs depending on the number of used tracks 3.1 to 3.6.
  • the paper waste and the Einziehzeit the individual feeder are, inter alia, in the diagrams of FIGS. 4 and 5 explained.
  • FIG. 2 shows a schematic representation of another way of paper feeding in a printing press.
  • all paper webs 3.1 to 3.6 are drawn in at the same time as the folding unit 5, this is referred to as the so-called multi-feed.
  • possible different track lengths of the various paper webs 3.1 to 3.6 were compensated for on the different web paths, that the collection devices started after the reel splitter 1 at different times with the paper feed and then transport the paper webs to the folding unit 5 at the same speed.
  • FIG. 3 shows a schematic representation of the method according to the invention when moving the paper webs 3.1 to 3.6 in a newspaper printing machine 6.
  • the functional units belonging to a web path such as reel splicer 1 and printing units 2 and their electrical components, are controlled jointly and different functional units of different web paths are controlled individually , This makes it possible, the paper webs on the different paths, for example, with different To drive / select speeds in different directions of rotation, different start and stop times of the paper webs.
  • FIG. 4 shown all paper webs 3.1 to 3.6 are fed simultaneously to the turning units 4.1 and 4.2, which offers a significant time advantage over the single feeder.
  • the paper web 3.4 can be guided to the folding unit 5 and the other paper webs 3.1 to 3.3, 3.5 and 3.6 successively to the folding unit 5, which prevents overlying the paper feed tips with the aforementioned disadvantages compared to the multi-feeding method.
  • FIG. 4 shows a diagram in which the theoretically calculated Einziehmakulatur is shown in the single and the magazine feeder of the new method.
  • Einziehmakulatur is that amount of paper, expressed in meters, understood that is useless and must be disposed of as waste due to paper feeding.
  • the paper waste is plotted in meters, with a partial area on the ordinate corresponding to 200 paper meters.
  • the number of pages of the printed product is plotted, with a partial area on the abscissa corresponds to an 8-page product.
  • the paper waste of the successively following individual feed which is shown in the diagram as a dashed curve, has an exponential course, wherein in a 48-page product over 1200 meters of paper were pulled through. This exponential course comes from the fact that initially the fourth paper web 3.4 in FIG.
  • the lower solid curve in the diagram shows the Textilmakulatur that is achieved when using the method according to the invention.
  • This linear curve results from the fact that the paper webs 3.1 to 3.6 are drawn in uniform and parallel up to the turning units 4.1 and 4.2.
  • the new process will save approximately 800 meters of paper waste on a 48-page product.
  • FIG. 5 shows a diagram in which the theoretically calculated retraction time for the single-feed and the magazine feeder is shown.
  • Diagram 4 a newspaper printing press with 6 web paths, each having an average web length of approximately 60 meters from the reel changer to the folding unit, was assumed.
  • the pull-in time is the time after which all paper webs are drawn in so far that printing can begin.
  • the pull-in time is plotted in minutes, with a partial range on the ordinate corresponding to 2 minutes.
  • the abscissa is analogous to the diagram FIG. 4 the number of pages of the printed product applied.
  • Both the retraction time of the single and the magazine feeder have a linear course. Since, however, the paper webs on the individual webs are drawn in parallel next to one another with the new method, the picking time is generally shorter. The solid curve thus has an overall lower slope in the diagram. For an 8-page product that uses only one paper web or one web path, the pull-in time is the same for the single-feed and the magazine feeder. With a 48-page product, the new process of drawing in all 6 paper webs saves about 10 minutes.
  • the new method of the invention allows the makeready time of the press equipment to be reduced, the utilization and production efficiency to be increased.
