Definitions

  • the invention relates to a printing unit for five and more colors for an offset web-fed rotary printing press according to the preamble of claim 1.
  • Such printing unit units are e.g. known as nine-cylinder printing unit units - also known as satellite printing unit units (DE-AS 23 37 259). Ten-cylinder satellite printing unit units are also known. Multi-cylinder printing unit units can be placed one on top of the other or side by side and produce multi-color prints in the run-up, whereby paper web transfers are necessary for side-by-side printing unit units.
  • the 4/0 print already in 2-up printing on the paper web is inevitably printed on one or both impression cylinders, which can lead to the feared duplication.
  • a further disadvantage with ten-cylinder printing unit units is that, when converting to 4/1 or 4/2 printing, the upper printing units of each printing unit involved have to be “wrapped” once or twice. For setting up (laying on or washing plates), the paper web must be torn or torn off or adjusted using relatively cumbersome driving mechanisms (DE-OS 27 41 596) so that work on the upper printing units of the printing unit is made possible.
  • the nine-cylinder printing unit units also have similar disadvantages, but here the 4/0 printing is generated with 1 x 4/0 in the first printing unit, and then to generate a 4/1 or 4/2 printing after the transfer to the second printing unit involved for the one- or two-color generation of the counterpressure, only one impression cylinder is involved, therefore the risk of duplication is only half as great as in the case of ten-cylinder printing unit units.
  • “Wrapped” printing units can usually be avoided with nine-cylinder printing unit units.
  • the invention has for its object to provide a printing unit for offset web-fed rotary printing presses with fewer cylinders and fewer devices for reversing the direction of rotation (reversing direction of rotation, clutches, cylinder adjustment devices) of the forme and blanket cylinders with at least the same achievable number of ink guide options in perfect and reverse printing comes out as the nine or ten-cylinder printing unit units described above in connection with other printing units. It should be able to offer maximum ease of use.
  • the "wrapped" printing units should be avoided.
  • the paper web should only travel short distances until it corresponds to the maximum possible color guidance, e.g. 4/2, is printed. An order of printing should be possible, through which duplication is largely avoided. Changes in pressure and offset pressure due to changes in machine speed should not occur.
  • the printing unit should be very well suited for assembly using the modular system.
  • the advantages that can be achieved with the invention consist in particular in that at least as many color guiding possibilities in face and reverse printing can be achieved with less effort in reversing gearboxes, clutches, cylinder adjusting devices and cylinders as in the previously known nine or ten-cylinder printing unit units.
  • the printing unit according to the invention offers a maximum of user friendliness, since the "wrapped" printing units are avoided.
  • the paper web only has to cover short distances until it is printed in accordance with the maximum color guide, for example 4/2. This is particularly advantageous for 4/1 and 4/2 printing.
  • the first two colors are printed on one side of the paper web, i.e. without printing.
  • the other four colors - two in sheet printing, two in reverse printing - are printed in the shortest possible way.
  • This order of printing largely prevents duplication.
  • Beautiful and reverse pressure changes due to machine speed No changes can occur because the sheet printing is always printed in direct counterprint to the backprint, and therefore there are no long paper web guides.
  • the printing unit according to the invention is very well suited for assembly according to the modular system.
  • a longitudinal shaft 1 of a fourteen-cylinder printing unit 2 (FIG. 1) or a twelve-cylinder printing unit 3 (FIG. 2) is driven in a known manner by a drive motor, not shown.
  • the fourteen-cylinder printing unit 2 consists of a base printing unit 4 and, viewed in the direction of travel of a paper web 5, of a first tier printing unit 6 placed on the base printing unit 4 and a second tier printing unit 7 placed thereon.
  • the twelve-cylinder printing unit 3 also consists of the basic printing unit 4, the first tier printing unit 6 placed thereon and a second tier printing unit 8.
  • the basic printing unit 4 consists of two printing units 9 and 10. They are mirror images of one another with respect to a vertical plane 11 which bisects the printing unit units 4, 6, 7 and 8.
  • Each of the printing units 9 and 10 consists of a plate cylinder 12, a blanket cylinder 13 and an impression cylinder 14 placed vertically on the blanket cylinder 13.
  • the blanket cylinders 13 can be pivoted downward from the impression cylinders 14 by means of known devices and can be pressed against one another.
  • the paper web 5 is 1/1, i.e. one color printing / one color printing, printed.
  • the paper web 5 is printed horizontally by the printing units 9 and 10 in 2/0, i.e. two colors backprint / no color in the Schotik. Both printing units can be stopped in any position of the blanket cylinder 13. All in all, the base printing unit allows the following color options with the appropriate paper web guide: 0/0, 1/0, 0/1, 2/0, 0/2, 1/1.
  • the first tier printing unit 6 consists of two printing units 15 and 16, which are arranged in mirror image to one another with respect to the plane 11.
  • Each of the two printing units 15 and 16 consists of a plate cylinder 17 and a rubber cylinder 18.
  • the rubber cylinders 18 are in operative contact with one another and thus form a printing point. They can be brought out of contact with known devices so that the paper web 5 passed between them is not printed.
  • the floor printing unit 6 allows the color options 0/0 and 1/1.
  • the second tier printing unit 7 consists of two printing units 19 and 20, which are arranged in mirror image to one another with respect to the plane 11.
  • Each of the two printing units 19 and 20 consists of a plate cylinder 21 and a rubber cylinder 22.
  • the rubber cylinders 22 are in operative contact with one another and thus form a printing point. Like the rubber cylinders 18, they can be brought out of operative contact, so that the paper web 5 passed between them is not printed.
  • the floor printing unit 7 allows the color options 0/0 and 1/1.
  • both the basic printing unit 4 and the first tier printing unit 6 are the same as the basic printing unit 4 and the tier printing unit 6 of the fourteen-cylinder printing unit 2. The same applies accordingly to them the above.
  • a second floor printing unit 8 is placed, which consists of a plate cylinder 24 and a rubber cylinder 25.
  • the rubber cylinder 25 is in operative contact with one of the rubber cylinders 18 of the first tier printing unit 6.
  • the rubber cylinder 18 forms with the rubber cylinder 25 a pressure point through which the paper web 5 is guided.
  • the rubber cylinder 25 is arranged on and off the rubber cylinder 18 using known devices.
  • the deck printing unit 6 permits the ink guide options 0/0, 1/1, the deck printing unit 8 - depending on which of the two blanket cylinders 18 the blanket cylinder 25 is in active contact with - the ink guide options 0/0, 1/0 and 0 / 0, 0/1.
  • Two standing shafts 26, 27 are necessary if the printing units 9, 10, 15, 16, 19, 20 of the printing unit units 4, 6, 7 are to work on different web-fed rotary press sections.
  • spur gear 36, spur gear 37, disengageable spur gear 38, spur gear 39 for driving the first counter-pressure cylinder 14, disengageable spur gear 40, spur gear 41 for driving the second counter-pressure cylinder 14, disengageable spur gear 42, spur gear 43 and spur gear 44 form a first gear train .
  • the spur gears 39, 67, disengageable spur gear 68 and spur gear 41 form a partial gear train.
  • spur gear 36 is driven by gear 32 and spur gear 44 by gear 31.
  • the two stacked printing units 6 and 7 are driven according to the invention by the two standing shafts 26 and 27.
  • the longitudinal shaft 1 of the printing unit 2 is made separable by a coupling 51. This makes it possible to divide the printing unit 2 into two different rotary printing press sections. It is e.g. possible to print a first paper web through the left printing unit 12, 13, 14 of the base printing unit 4 and the first tier printing unit 6, and a second paper web through the right printing unit 12, 13, 14 and the second tier printing unit 7, and feed them to rotating press sections at different speeds.
  • the floor printing unit 6 and 7 must be optionally drivable and connectable and disconnectable from both standing shafts 26, 27.
  • the printing units 15 and 16 of standing shaft gear 33 or 35 via the drive train optionally spur gear 52, disengageable spur gear 53, spur gear 54 for driving the right plate cylinder 17, spur gear 55 for driving the right rubber cylinder 18, spur gear 56 for driving the left rubber cylinder 18 , Spur gear 57 for driving the left plate cylinder 17, removable spur gear 58, spur gear 71, or optionally gear 35, standing shaft 27 driven.
