Definitions

  • the invention relates to a sheet-fed printing machine according to the preamble of claim 1.
  • a sheet-fed press with several printing units wherein each of the printing units comprises a counter-pressure cylinder, a rolling on the impression cylinder transfer cylinder or blanket cylinder, rolling on the transfer cylinder form cylinder or plate cylinder and an inking unit and a dampening unit.
  • the impression cylinders, the transfer cylinders, the inking units and the dampening units of the printing units are driven by a main drive.
  • the cylinders of the printing units are associated with their own drives or direct drives, which drive the form cylinder decoupled from the main drive of the printing press eigenmotorisch.
  • each of the forme cylinders in addition to the direct drive is associated with a control device or control device which drives the forme cylinder in the continuous printing operation synchronously with the respective transfer cylinder of the corresponding printing unit and thus synchronously with the main drive of the printing press.
  • the present invention is based on the problem to provide a novel sheet-fed printing machine.
  • an imaging device is integrated into at least one printing unit, with the aid of which a printing plate can be imaged in the printing unit.
  • a imaging device into a printing unit of a sheet-fed printing press, the form cylinder of which can be driven independently of the main drive of the sheet-fed printing press. This can be done in the printing unit, a picture of a printing plate.
  • Fig. 1 shows a section of a sheet-fed printing machine according to the invention in the area of a printing unit 10, a printing unit 10 seen in the transport direction of the sheet downstream Lackwerks 11 and seen in the transport direction of the sheet the coating unit 11 downstream boom 12, wherein in the region of the arm 12, the printed Sheet with the aid of a conveyor system 13, the conveying direction is visualized in Fig. 1 by an arrow 14, are discharged to form a delivery stack 15 from the sheet-fed press.
  • Printing sheets to be printed are conveyed or moved by means of so-called sheet guiding cylinders 16 through the sheet-fed printing machine, the sheet guiding cylinders arranged in the area of the printing units 10 or coating units 11 being also referred to as impression cylinders 17. Between the counter-pressure cylinders 17 of adjacent printing units 10 or coating units 11 at least one further sheet guiding cylinder 16 is positioned, which is also referred to as a transfer cylinder 18.
  • a transfer cylinder 19 of the printing unit 10 rolls off a transfer cylinder 19, which is also referred to as a blanket cylinder.
  • a transfer cylinder 19 of the printing unit 10 rolls off a forme cylinder 20, which is also referred to as a plate cylinder, and carries at least one printing plate.
  • an inking unit 21 cooperates, via which printing ink is applied to the printing cylinder positioned on the forme 20.
  • the ink is transferred via the transfer cylinder 19 to print sheets to be printed, which are moved through a gap between the transfer cylinder 19 and the impression cylinder 17 therethrough.
  • inking unit 21 In addition to the inking unit 21 is associated with the forme cylinder 20 of the printing unit 10 and a non-illustrated dampening unit to apply in addition to the ink and a fountain solution to the positioned on the forme cylinder 20 printing form.
  • printed impression sheets can be finished with a paint image, wherein in the area of the coating unit 11 on the impression cylinder 17, a form cylinder 22 rolls, wearing a paint form. Paint is applied to the paint form positioned on the forme cylinder 22 with the aid of a metering device, wherein the metering device is formed by a applicator roll 23 and a chamber doctor blade 24 cooperating with the applicator roll 23.
  • both the printing unit 10 and the coating unit 11 each have a drying device 25 assigned, which is arranged in each case in the region of the corresponding impression cylinder 17.
  • the sheet-guiding cylinders 16 namely both the counter-pressure cylinders 17 and the transfer cylinders 18, can be driven by a main drive of the sheet-fed printing machine in the continuous printing operation.
  • this main drive continues to be in the range of a printing unit 10 of the transfer cylinder 19, the inking unit 21 and the dampening unit, not shown, driven.
  • the forme cylinder 20 of each printing unit 10 is decoupled from the main drive of the sheet-fed printing machine in the decompression mode, wherein the form cylinder 20 is assigned a direct drive for this purpose.
  • the form cylinder 20 are decoupled from the main drive, but synchronized with the same, self-powered drivable.
  • the metering device and the forme cylinder 22 are driven by the main drive in the continuous printing operation.
  • a imaging device 26 by means of which a printing plate can be imaged in the printing unit 10.
  • a coating unit 11 such an imaging device may be integrated in order to image a coating form in the coating unit 11.
  • the printing forms or coating forms that can be imaged with the aid of the imaging device 26 can be both plates and sleeves.
  • An imaging device 26 may be permanently integrated in a printing unit 10 or a coating unit 11. On the other hand, it is also possible to implement a imaging device 26 displaceable, so that they can be integrated as needed in different printing units or coating units of a sheet-fed press or can be used on different sheet-fed presses.
  • writable printing forms or coating forms or also rewritable printing forms or coating forms can be used.
  • writable printing forms or coating forms can be kept in a magazine as plates, for example, then removed for example in the sense of an automatic plate change from the magazine and stretched on the forme cylinder of the printing unit, and then perform the imaging in the printing unit.
  • reusable printing forms or lacquer forms are preferably used which can then remain on the forme cylinder and can be erased or de-imageable with the aid of the imaging device and can then be newly imaged.
  • an imaging method in which an imaging material is applied to a printing form via a thermal transfer ribbon and subsequently fixed on the printing form by means of a laser.
  • the imaging of printing forms in a printing unit of a printing machine with the aid of a imaging device is also referred to by the keyword "computer to press / direct imaging" and has hitherto been known only in web-fed printing presses. With the present invention, this technique is now made available for the first time in sheet-fed presses.
  • the or each printing unit in which a imaging device is integrated, designed as a so-called imprinter work, which serves the individualization of printed products with individual impressions in a static printed image.
  • a printing form imaging can be carried out while other printing units or coating units of the printing press are operated in progress.
  • a printing form imaging can be carried out while other printing units or coating units of the printing press are operated in progress.
  • the forme cylinder 20 of the printing unit 10 is transferred to a print position, wherein subsequently the printing form imaging is performed on the forme cylinder 20.
  • the inking rollers and the or each dampening roller are placed against the forme cylinder 20 for pre-inking.
  • the forme cylinder 20 of the printing unit 10 is transferred to a printing position, so that the same is then integrated again into the printing process.
