Definitions

  • the invention relates to a web-fed rotary high-pressure printing machine according to the preamble of claim 1.
  • each printing unit comprises an impression cylinder, a plate cylinder carrying one or more high-pressure forms (flexographic printing plates) and a inking system which essentially comprises a color transfer roller designed as an anilox roller and a chamber doctor blade associated therewith.
  • the AT 50 732 T2 and the US 4,628,816 each show web-fed rotary printing presses, with successively arranged printing units having different sized forme cylinder. However, it is not intended to bring the form cylinder optionally in printing position to produce different newspaper-like products can.
  • the invention has for its object to provide a web-fed rotary printing machine.
  • the section length of the at least one printing unit downstream folding machine is changeable, whereby the folding section length can be adapted to the printing section length by adjusting the folder, whereby a highly efficient production of printed products is made possible.
  • the invention also offers the user an economically attractive possibility of printing a second format without the otherwise unavoidable waste of the same format.
  • the mere omission of the additional costs of the waste (paper and cutting equipment) which otherwise arise can result in a more favorable amortization of the solution according to the invention.
  • a second printing press for the second format can be completely eliminated and, moreover, the printing press suitable for two formats can be utilized to a particularly high degree, whereby the economy of the solution according to the invention is optimized.
  • the printing machine for the second format can initially only be prepared and the necessary components or the corresponding module for the realization of the second format can be supplied only when needed, eg. B. when the printer has in turn received a corresponding order.
  • the delivery time or commissioning of such components or modules is generally much shorter than that of a complete machine.
  • Such an option on a second format can for give users a significant time advantage over their competitors.
  • the option of a second format for the user constitutes a risk minimization in the event that the order for the second format should not materialize.
  • the additional cost of the variable folder in the initial investment is made up for by the high flexibility of the press by far.
  • the format change during the run of the other format can be completely prepared, d. H. all new printing plates of the one cylinder can already be manufactured and laid while still printing with the printing plates of the other cylinder; So it is a flying plate change possible. If, in accordance with a preferred development of the invention, additional roll changers with divided arms are used, paper webs with the next paper web width can advantageously also be prepared on the running printing press. Thus, the format change for the printing unit can be made as fast as possible, almost at the touch of a button.
  • a high level of topicality can be achieved.
  • a second newspaper can be printed in a different format, or a running, non-time-critical cross-country order can be interrupted only briefly to print the current second product, since a quick change back to the original printed product is possible.
  • At least one of the two journals is detachably formed by the cylinder body of the cylinder, so that the Cylinder body can be exchanged for a cylinder body of different diameters. This makes it possible for the user to quickly change the format by purchasing additional cylindrical bodies of different diameters. This results in an economic flexibility for the adaptation of future formats of existing products or newly acquired products for the wage pressure of users.
  • the machine manufacturer has the improved possibility of mass production and series production, since only the cylinder bodies are subject to circumferential variability and the other components can be standardized.
  • rotary high-pressure machine or rotary high-pressure printing plant comprises a printing tower 01, which is traversed in a conventional manner by a printing substrate 02, in particular a paper web 02 for printing on both sides of the printing substrate 02 in four-color printing.
  • the high-speed web-fed rotary printing press comprises eight printing units 03.
  • Four printing units 03 are arranged one above the other and two printing units 03 each lie in pairs across from.
  • the respective opposite printing units 03 are arranged axially symmetrically.
  • Each printing unit 03 consists essentially of a cylinder 04, z. B. impression cylinder 04, a cylinder 06, z. B. form cylinder 06 or plate cylinder 06 and a inking system 07 for the forme cylinder 06, which in the present embodiment, a ink transfer roller 07, namely an anilox roller 07, in particular an anilox roller 07 and an anilox roller 07 associated chambered doctor blade 08 includes. Between anilox roller 07 and chamber doctor blade 08 can also be arranged one or more applicator rollers.
  • the inking system can also be designed, for example, as a pumping inking unit or as a conventional inking unit with adjustable inking blades.
  • the forming or plate cylinder 06 carries one or more high-pressure forms, which in the present embodiment may be designed as flexographic printing plates and made of flexible plastic with a dimensionally stable support plate (in particular of metal), d. H. the printing unit 03 is formed as a flexographic printing unit 03.
  • each printing unit 03 comprises a further cylinder 09 whose outer diameter is different from the outer diameter of the forme cylinder 06 and which can be brought into the printing position instead of the forme cylinder 06.
  • This further cylinder 09 is likewise designed as a plate cylinder 09 and can likewise carry one or more high-pressure molds, which can preferably be designed as flexographic printing plates.
  • Each cylinder 04; 06 and / or the anilox roller 07 and / or at least one ink transfer roller between anilox roller 07 and forme cylinder 06 optional arranged ink transfer roller may preferably be driven by its own angular position-controlled electric motor, ie the respective electric motor drives exclusively the associated cylinder or roller.
  • FIG. 2 schematically shows one of the printing units 03 of the printing tower 01 according to FIG.
  • the further cylinder 09 is formed in the manner of a Imprinterzylinders 09 and has an axial length, the z. B. is smaller than or equal to the axial length of the impression cylinder 04, the forme cylinder 06 and the Aniloxwalze 07.
  • the circumference of the other cylinder 09 is different from the circumference of the forme cylinder 06, that is larger or smaller than this.
  • the forme cylinder 06 or plate cylinder 06 is in contact with the anilox roller 07 and the impression cylinder 04.
  • the plate cylinder 06 is designed in terms of its width or axial length in the largest required format.
  • the easily usable in flexographic printing systems further cylinder 09 or imprinter cylinder 09 is used as a second format cylinder 09 and for the smaller, d. H. designed narrower format.
  • the circumference and the bearing geometry are selected according to the desired format.
  • the circumference of the second format cylinder 09 may be larger or smaller than that of the plate cylinder 06.
  • the diameter of the gapless impression cylinder 04 is designed according to the format with the longest runtime or the largest support height.
  • folding machine 23 must be set to the new format, ie the section length of the printing units 03 in the new format must be set to the section length in the folder 23.
  • the printing unit 03 itself, only an adaptation of the rotational speed of the directly driven anilox roller 07 and the impression cylinder 04 to the new peripheral speed of the second format cylinder 09 is required. If, alternatively, the peripheral speed of the anilox roll 07 and the impression cylinder 04 is to be maintained relative to the fold, it is sufficient to adapt only the speed of the second format cylinder 09 to the new cylinder circumference.
  • the second format cylinder 09 can be brought into the printing position instead of the plate cylinder 06 and the new format can be printed.
  • both plate cylinder 06; 09, d. H. the plate cylinder 06 and the second format cylinder 09 each with a different number of uses can be occupied.
  • This can, up to certain limit dimensions, by the use of a full-circumferential plate or by the arrangement of several plates provided with closures on the circumference of the respective cylinder 06; 09 can be achieved.
  • the arrangement of the closures is preferably carried out in a circumferentially offset manner in order to avoid a continuous vibration excitation.
  • the second embodiment includes the concept of a genuine change cylinder, which can be used either for the plate cylinder 06 or for the second format cylinder 09. In the case of the described embodiment, this concept is realized for the second format cylinder 09, but it can also be realized for the plate cylinder 06.
  • the axial length of the second format cylinder 09 may be equal to the axial lengths of the impression cylinder 04, the forme cylinder 06 and the anilox roller 07.
  • the second format cylinder 09 here comprises a cylinder body 11 and two journals 12; 13, which are releasably secured to the cylinder body 11 via flanges 14 o.
  • the journals 12; 13 are about bearings 16; 17 mounted on an adjusting unit 18, which in turn is adjustably mounted on the frame 19.
  • the adjusting unit 18 which in the case of the exemplary embodiment is designed as a linear displacement unit 18 (for limited format variability also three-ring / four-ring bearing), permits a linear adjustment of the second format cylinder 09 in a plane 21 which is perpendicular to the plane 22 , which is defined by the axes of rotation of the impression cylinder 04 and the anilox roller 07.
  • the bearings 16; 17 are received by the adjusting unit 18 and are displaceable with this in said plane 21.
  • FIGS. 6 to 8 relate to a variable folder 23, that is, to a variable folder 23; H. a folding unit 23 with variable section length, as it can be directly or indirectly downstream of the printing units 03 and the printing tower 01.
  • FIG. 6 an embodiment of a variable folding apparatus 23 with system 7: 7 is shown.
  • the type of such a folder can, for example, from the EP 02 57 390 B1 be removed.
