Definitions

  • the invention relates to a printing unit of a web-fed printing press according to the preamble of claim 1.
  • printing units of web presses have multiple printing units, each printing unit having a transfer cylinder, a plate cylinder, an inking unit and optionally a dampening unit.
  • the form cylinder are also referred to as a plate cylinder and the transfer cylinder as a rubber cylinder.
  • printing units can have impression cylinders, wherein an impression cylinder can interact with one or more transfer cylinders of different printing units.
  • the impression cylinders are also referred to as satellite cylinders, which is why printing units with at least one impression cylinder are also referred to as satellite printing units.
  • satellite printing units which have impression cylinders
  • printing units are also known which do not have impression cylinders, wherein in printing units without impression cylinders, the transfer cylinders of two printing couples roll on each other.
  • printing forms are positioned, which carry the printed image to be printed. Then, when the print image to be printed changes, printing forms must be exchanged or reprinted. For this, the printing operation on the printing press must be interrupted. Accordingly, during the execution of a printing plate change or the execution of a printing form illustration, a printing unit is not available for printing. This limits the production availability of a printing unit.
  • the present invention is based on the problem to provide a novel printing unit of a web-fed printing press.
  • each printing unit comprises a form cylinder unit having at least two forme cylinders, wherein if or when a form cylinder of a form cylinder unit is set to the transfer cylinder of the respective printing unit, the or each other form cylinder of the corresponding form cylinder unit is turned off by the transfer cylinder of the respective printing unit.
  • each printing unit of the printing unit according to the invention comprises a molding cylinder unit having at least two forme cylinders.
  • a form cylinder of the form cylinder unit is employed in the printing operation of the transfer cylinder of the respective printing unit.
  • the or any other form cylinder of the corresponding form cylinder unit is parked in the printing operation of the transfer cylinder of the respective printing unit.
  • printing plate changes or printing form illustrations can be carried out parallel to the printing operation on the forme cylinders offset from the transfer cylinder of the respective printing unit. As a result, the production availability of the printing unit according to the invention can be increased.
  • the forme cylinders of each forme cylinder unit are each mounted on a common carrier, so that the forme cylinders of each forme cylinder unit can be displaced together relative to the transfer cylinder of the respective printing unit.
  • Fig. 1 shows a schematic representation of a printing unit 10 according to the invention of a web-fed rotary printing press, wherein the printing unit 10 of the Fig. 1 is designed as a satellite printing unit.
  • the printing unit 10 has the Fig. 1 four printing units 11, 12, 13 and 14, wherein each printing unit 11, 12, 13 and 14 has a transfer cylinder 15, and wherein all transfer cylinders 15 roll on an impression cylinder 19, which is also referred to as a satellite cylinder.
  • each printing unit 11, 12, 13 and 14 also has a form cylinder unit 16, a non-illustrated inking unit and preferably also not shown dampening unit.
  • the form cylinder unit 16 of each printing unit 11, 12, 13 and 14 has in the illustrated embodiment, two form cylinder 17 and 18. Then, when in the printing operation of the form cylinder 17 is employed on the transfer cylinder 15 of the respective printing unit 11, 12, 13 and 14, is the other form cylinder 17 of the corresponding form cylinder unit 16 from the transfer cylinder 15 of the respective printing unit 11, 12, 13 and 14 parked.
  • the employed in the printing operation of the forme cylinder 15 of the respective printing unit 11, 12, 13 and 14 form cylinder 17 a form cylinder unit 16 is the drive side to the respective printing unit 11, 12, 13 and 14 coupled.
  • the parked in the printing operation of the transfer cylinder 15 of each printing forme cylinder 18 a form cylinder unit 16 is disconnected on the drive side of the respective printing unit.
  • the forme cylinders 17 and 18 of each forme cylinder unit 16 are each mounted on a common carrier. Accordingly, the forme cylinders 17 and 18 of a forme cylinder unit 16 are displaceable relative to the transfer cylinder 15 of the respective printing unit 11, 12, 13 and 14, respectively, on the one hand for parking and adjusting linearly adjustable and rotatable in the off state relative to the transfer cylinder 15 of the respective printing unit.
  • the attached to a transfer cylinder 15 of a printing unit 11, 12, 13 and 14 employees and the drive side coupled to the respective printing unit form cylinder 17 is used in the printing operation, the application of a print image or partial print image on a substrate to be printed.
  • a printing form change or a Druckformbegged feasible When executing a printing plate change, a printing plate can be exchanged manually or automatically on the respective forme cylinder 18.
  • an imaging device is preferably employed on it, with the aid of which an old printed image can be deleted from the printing form positioned on the forme cylinder 18 and subsequently a new printed image can be applied.
  • each mold cylinder unit 16 has more than two forme cylinder, then again only one of the forme cylinder is employed in the printing operation of the transfer cylinder 15 of the respective printing unit, and wherein the remaining forme cylinder of the printing unit 16 in the printing operation are turned off by the respective transfer cylinder 15.
  • the printing unit 10 is preferably operated as follows for executing a printing plate change or printing plate imaging on at least one printing unit thereof: After completion of a print job, the inking unit (not shown) and optionally the non-illustrated inking unit are printed on at least one printing unit 11, 12, 13 and 14, respectively. shown damping unit parked by the employed in the previous printing operation to the transfer cylinder 15 form cylinder.
  • the form cylinder unit 16 of the respective printing unit 11, 12, 13 and 14 is displaced such that the employee employed in the previous printing operation to the transfer cylinder 15 of the respective printing forme cylinder of the transfer cylinder 15 and turned off in the previous printing operation of the transfer cylinder 15 of the respective printing unit turned off form cylinder is made to the transfer cylinder 15 of the respective printing unit.
  • the inking unit and optionally the dampening unit is employed at the employed for the subsequent printing operation of the transfer cylinder 15 of the respective printing forme cylinder.
  • Parallel to the printing operation to be carried out subsequently, a printing plate change or a printing plate imaging is carried out on the form cylinder, which has now been parked by the transfer cylinder 15 of the respective printing unit.
