Definitions

  • the invention relates to a sheet-fed rotary printing machine for optional straight printing or perfecting, in which the sheet is based on the principle the trailing edge of the sheet is turned.
  • a printing press in which the sheet with the so-called three-drum turn (three Transfer drums between the printing units) can be turned is by the document DE 23 54 418 known. Between the two printing units of this printing machine, between which the turning takes place is seen in the direction of the sheet travel, a first Transfer drum with a simple, large diameter, a second transfer drum - the so-called Storage drum - with double-large diameter and a third transfer drum - The so-called turning drum - arranged with a simple-large diameter.
  • the actual turning device consists of the storage drum and the turning drum, whereby the turning drum is equipped with the turning gripper.
  • a disadvantage of this printing machine is that the sheet is conveyed between them during conveying two printing units in both operating modes due to the simple-large transfer and Reversing drum is subject to a strong curvature, which is disadvantageous when processing Materials of greater thickness.
  • Document DE 44 03 884 shows a printing press in which the sheet is equally turned using the so-called three-drum turn.
  • This printing machine is equipped with a transfer drum between the printing units.
  • a so-called reversing box is inserted between two adjacent printing units to accomplish the perfecting.
  • the turning box is arranged after the transfer drum of the respective printing unit and it consists of the storage and the turning drum, both of which, like all sheet-guiding cylinders (printing cylinders, transfer drums), have a double-large diameter.
  • This turning box is that the turning drum with two turning gripper systems is equipped.
  • the double-sized cylinders of the three-drum turn ensure a slender sheet run, but the turning drum is only expensive because it contains two reversible grippers.
  • the sheet-fed rotary printing press goes with regard to the turning device (Storage drum, turning drum) based on the knowledge that a simple-large Turning drum 9 with only one turning gripper, the turning drum 7 with little effort can be manufactured.
  • the single-sized turning drum 7 is double or multi-sized turning drum with the appropriate turning grippers an inexpensive Variant.
  • the advantage of both operating modes is the double or triple diameter of the first transfer cylinder, since the large radius of curvature means that Materials of greater thickness - without being damaged - guaranteed.
  • phase position in the printing presses in the printing units with possible phase equality in all or some printing units is guaranteed after the inserting device has been inserted in the face printing.
  • a defined arrangement of the storage drum in the turning device can ensure that the phase position of the printing units of a printing press with a turning device in straight printing is equal to the phase position of the printing units of a printing machine without a turning device.
  • FIG. 1 shows a sheet-fed rotary printing press for straight printing, four printing units 1.1-1.4 of the sheet-fed rotary printing press being shown.
  • the printing unit 1 consists of the printing, rubber and plate cylinders 2, 3, 4 and a transfer cylinder 5.
  • Printing cylinder 2 and transfer cylinder 5 have a double-large diameter compared to plate and rubber cylinders 4, 3.
  • the sheet conveying direction 6 is indicated by an arrow.
  • Fig. 1 shows the prior art.
  • Fig. 2 shows Fig. 1 with a turning device 7.
  • the turning device 7 is provided, which is part of a three-drum turn, which seen in the sheet conveying direction 6 from a transfer cylinder 5.2 with double large diameter, a storage drum 8 with a double-large diameter (2nd transfer cylinder) and the turning drum 9 with a single-large diameter (3rd transfer cylinder).
  • a single-large diameter for the turning drum 9 means that an arc 10 is conveyed per revolution of the turning drum 9.
  • a turning gripper (not shown) is arranged on the turning drum 9, which is designed, for example, as a pliers gripper and is effective in straight printing as well as in perfecting.
  • the turning device 7 consists of the storage drum 8 (double-large diameter) and the turning drum 9 (single-large diameter).
  • Fig. 3 shows a three-drum turn in a sheet-fed rotary printing press after one second variant.
  • a transfer cylinder 5.2 with a triple-large one Diameter between two printing units 1.2; 1.3 with a printing cylinder 5 with a double-large diameter, a transfer cylinder 5.2 with a triple-large one Diameter, a storage drum 8 with a double-large diameter and the turning drum 9 is provided with a single large diameter.
  • the only transfer cylinder 5 between the pressure cylinders 2 points between those not involved in the turn Printing units 1 on a triple-large diameter.
  • Fig. 4 shows a three-drum turn according to a third variant.
  • this version are between two printing units 1.2; 1.3 with a triple-large impression cylinder 2
  • the only transfer cylinder 5 between the impression cylinders 2 between not at the The printing units 1 involved have a double-large diameter.
  • the turning device 7 also consists of the embodiments according to FIGS. 3 and 4 the storage drum 8 and turning drum 9 and the turning device 7 can between each any adjacent printing units 1 can be arranged.
  • the turning device 7, consisting of the turning and storage drum 9, 8 with different contents (different diameters of the turning and storage drum 9, 8) as a plug-in unit, enables the phase position of the printing units 1 of the face printing machine according to FIG. 1 to also be used on printing machines in face printing Turning device 7 after the turning device 7 according to FIGS. 2-4 can be maintained.
  • the prerequisite for this is the arrangement of the storage drum 8 at a defined distance a (FIG. 2) from the base surface which ensures the phase relationship. 1 and 2 show, the first and the third printing unit 1.1; 1.3 and the second and fourth printing units 1.2; 1.3 the same phase angle at a phase angle a of 22.5 ° in both machine configurations.
  • the sheet 10 is up to the turning device 7 as in straight printing treated.
  • the sheet 10 passes through the storage drum 8 with the leading edge first the contact point 8.9 of the storage and turning drum 8.9 and is at the rear edge seized by the turning gripper of the turning drum 9 and then turned the following Printing cylinder 2 fed so that in the subsequent printing units 13; 1.4 the Back pressure can be applied.
