Definitions

  • the invention relates to a sheetfed offset printing press consisting of at least one Printing unit with a printing cylinder, a blanket cylinder in contact with it and a plate cylinder, the plate cylinder being an inking and dampening unit assigned and to the printing cylinder of the last printing unit (seen in the sheet conveying direction) two transfer drums are arranged downstream.
  • a sheet-fed offset printing press in which within the Sheet discharge device two transfer drums are arranged.
  • the two transfer drums are placed between the impression cylinder and the sheet delivery.
  • a special device can be assigned to the upstream transfer drum.
  • Such special devices can include drying devices, powder devices, painting devices or the like.
  • the object of the invention is to provide a sheetfed offset printing press in which by installing several special devices in the area of the display the range of functions the sheetfed offset press is expanded.
  • the printing unit 1 includes an inking and dampening unit 14 which cooperates with a plate cylinder 12.
  • a blanket cylinder 13 is the Transfer color to a printing cylinder 11.
  • transfer drums 21; 22 with a closed Surface are equipped and can thus act as an impression cylinder.
  • the transfer drum 22 interacts with a chain 31. This is a front Chain deflection wheel 32, a rear chain deflection wheel 33 and others, not designated here or guided guide elements, not shown, on a defined path.
  • a delivery stack 34 for storing the printed Printed sheets.
  • the first transfer drum 21 is an anilox offset printing unit as a special device 4 assigned.
  • an ink roller 45 with ink chamber doctor blade 44 a dampening roller 47 with dampening chamber doctor blade 46 for supplying dampening solution arranged to the inking roller 43.
  • the anilox offset printing unit 4 is designed that it can also be disengaged.
  • the second transfer drum 22 is a drying device 5 as special devices and / or a cutting device 6 is assigned.
  • the printing sheet is conveyed to the printing cylinder 11 and with on its face side the illustrated conventional printing unit 1 printed with color.
  • the printed sheet in the last printing unit 1 shown in the figures as a rule several Receive color orders on its face side and possibly on its reverse side. After this last color application on the face printing side, it is now over a Pass the gripper system, not shown, to the transfer drum 21 and further device Sheet run in contact with the rubber cylinder 41 of the anilox offset printing unit 4 (see Course of the entered arrows). This means that a layer of ink is applied to the reverse side.
  • the printed sheet is then taken over by the second transfer drum 22 by the gripper, not shown, grasp this. Now the cutting device 6 can Insert and cut the printed sheet. Then the printed sheet comes in the area of the drying device 5, so that drying of the Face-up printing can be done.
  • the printed sheet is removed from the grippers (not shown). the chain 31 taken over, promoted to the area of the display 3 and there on the Delivery pile 34 filed.
  • FIG. 1 A further embodiment of the invention is shown in FIG.
  • the structure of the Printing unit 1 including the transfer drum 21 corresponds to that described under Figure 1 Example. In this example, however, there are two more transfer drums 23; 24 arranged. This offers space for several special facilities both at the Beautiful as well as the reverse side.
  • the transfer drums are for constructional reasons 22; 23; 24 half the size of the transfer drum 21.
  • the transfer drum 21 is a conventional inking unit 8, consisting of a Inking unit 81, a dampening unit 82, a plate cylinder 83 and a blanket cylinder 84, assigned.
  • Lacquer module 9 arranged and a short application unit 7 can be placed on the transfer drum 23 is.
  • the short application unit 7 can in turn be an anilox offset printing unit. It is also possible to use an anilox printing unit.
  • a transfer device 5 is assigned to the transfer drum 24 here, for example.
  • the printing of the printed sheets and their sheet travel corresponds to that described in FIG. 1. Again, the back pressure takes place on the transfer drum 21, but here with the conventional inking unit 8. The printing sheet then becomes the transfer drum 22 passed, on which this is then provided with a paint by the paint module 9 can be. In the further sheet run, the printed sheet can then on the transfer drum 23 through the short application unit 7 arranged there with a paint or a paint application be provided. The previously applied coating can be on the transfer drum 24 be dried by the dryer 5.
  • the invention is not limited to the exemplary embodiments described with reference to FIGS. 1 and 2.
  • transfer drums 21; 22; 23; 24 it is also possible still use transfer drums.
  • the condition is that the number of used Transfer drums is always an even number, otherwise the reverse side of the deposit would point upwards.
  • the single transfer drum must always be equipped with a surface adapted to the function. If backprinting or painting is carried out, the surface must be closed and be resilient. If the printed sheet is only to be dried, that is enough Equipment as transfer drum ..
