Definitions

  • the invention relates to a simulation system for a printing press according to the preamble of claims 1, 6, 7 or 8.
  • Such a simulation system is valuable for the designer as well as for the potential buyer of a printing press, in order to be able to estimate with little effort exactly whether the equipment of a printing press being planned with various modules is sufficient to fulfill certain, expected printing tasks or to optimize the structure of such a printing press.
  • This can be an optimization from a cost perspective, i. H. in which a machine structure with the smallest possible number of modules is determined, which is able to carry out the expected printing tasks, or an optimization with regard to the simplest possible web guide, which can be quickly adjusted by the operating personnel of the planned machine, to avoid through Color changes in the individual printing units of the machine due to job changes etc.
  • a printing machine e.g. B. for colored newspaper printing
  • modules generally include reel splicers, which unwind the paper to be printed from reels, connecting the end of a reel with the beginning of a subsequent one to form an endless web.
  • Another module are printing towers, in which a web delivered by the reel changer is printed on the front and back.
  • a turning deck where the printed webs, possibly in the longitudinal direction in each case Partial webs corresponding to a single or double sheet of the finished product are disassembled, turned as required and laid into strands one above the other.
  • Another module are folders, the former of which is fed a strand coming from the turning deck in order to be longitudinally folded, cut into individual signatures or books and, if necessary, also cross-folded.
  • a roll changer can be operated with paper rolls of different widths, e.g. B. with rolls of a "full" width, which corresponds to the width of two double pages of the finished product, or with rolls of three quarters, half or a quarter of the full width. Rolls that are not full width can also vary be positioned on the reel changer.
  • a printing tower for four-color printing there are different ways of guiding a paper web, one in which the front and back are printed in four colors, and possibly several others with reduced color, which allow a second web to be processed in the same printing tower at the same time.
  • the different possibilities of web guiding in the turning deck determine the arrangement in which the printed webs, brought together in one strand, reach the folders, and thus the position of pages with different colors in the finished product.
  • a potential buyer of a printing press has precise ideas about the arrangement of four-color and less-colored pages in a finished product that the machine is to be realized. Starting from such a predefined arrangement, it is in principle possible with the aid of a computer, provided there is sufficient computing time available, to determine the simplest and least expensive machine configuration that is able to implement the desired product structure. If this turns out to be unexpectedly complex, the potential buyer may opt for a different product structure, and in turn a machine configuration must be determined for this product structure, which allows the product structure to be implemented with the smallest possible number of modules.
  • the magazine "Polygraph" 21, 96, pages 44 to 47 describes a production planning system for a newspaper press in which the printing press is represented by means of graphic symbols.
  • DE 39 39 673 A1 discloses a method for printing plate coverage on the printing cylinders of a printing press, wherein various boundary conditions can be specified.
  • the invention has for its object to provide a simple simulation system To create production planning for a printing press.
  • Each of the fields of the display image can be compared here with an installation space unit of the printing press corresponding to the model, which is occupied by a module represented by the symbol displayed in the field.
  • the user always has a complete overview of the configuration of the machine to be simulated, which enables him to easily recognize errors in the model entered.
  • the comprehensibility of the display image for the user is additionally improved in that spatially adjacent modules of the printing press to be simulated are each assigned adjacent fields of the display image.
  • the display image is similar to a schematic drawing of the machine to be simulated.
  • z. B. can differ in size or proportions, with a given type of module can only be placed in one group of fields. So z. B. a group of fields can be reserved for reel changers or turning decks. Conversely, however, symbols of different types of modules can certainly be placed in the fields of a group; in particular, a further group of fields can in each case hold symbols of printing towers or of folding devices. Several, similar but not identical symbols can be assigned to each type of module, each of which corresponds to one of different operating modes of the module.
  • Printed webs depending on what is chosen for the roll changers and the printing towers Operating mode - arriving in different numbers and in different colors at the turning decks can be deflected, offset or turned by them in a variety of different ways and then fed to a folder, the course of the webs determined by the turning deck at which point in the finished product Pages with a certain color appear.

H. to arrange a certain type of web guide, whereupon the model of the printing press would be completely defined and the resulting product structure could be calculated.
  • the system since the number of path guidance options in the turning decks is large and it is generally difficult for a user of the system to imagine what the product structure resulting from a selected path guidance in the turning deck is, it is expedient that the system, if not all possible web guides in the turning decks, but at least for a large number of them the resulting product structures are calculated and the user is able to specify selection criteria in order to then check whether there is one of the calculated product structures that meets these criteria. In order to limit the computing effort, it is expedient to disregard path guides that are technically feasible but are not practical for various reasons.
  • the resulting structure of a product can be directly illustrated to the user in a graphical representation, in which each page of the product is assigned a group of color symbols, in which the number and color of the symbols corresponds to the colors of the relevant page in the finished product.
