Definitions

  • the invention relates to a sheet-fed rotary printing machine for the production of single-sided multi-color printing or face and face printing in a row design with at least one turning device and devices for processing both paper and cardboard.
  • a multi-color sheet-fed rotary printing press of the type outlined above is already known from DE-OS 2452167.
  • the impression cylinder of each printing unit of this machine and the turning cylinder arranged between two printing units are double in diameter.
  • a suction system provided on the turning cylinder detects the rear edge of the freshly printed sheet lying on the smooth sheet guiding surface of the impression cylinder.
  • the suction system transfers the detected sheet trailing edge to a gripper system, which then swings out again during the further rotary movement of the turning cylinder and now transfers the sheet with the trailing edge first to the gripper system of the subsequent impression cylinder.
  • the suction system is designed as part of a coupling of a double swing arm.
  • the known multi-color sheet-fed rotary printing press is basically suitable for processing cardboard.
  • the trailing edge of the sheet has to be removed from the smooth counterpressure surface of the impression cylinder by means of a suction system, during the transfer process the trailing edge of the sheet to the gripper system of the reversing cylinder, despite the use of a double rocker, a kinking of the rear sheet area is inevitable, which means that the processing of thicker cardboard, if any , is only possible in very low speed ranges.
  • the above-mentioned kinking of the trailing edge of the sheet increasingly causes the sheet to be torn off from the suction system due to the stiffness of the cardboard at higher machine outputs.
  • a sheet turning device for rotary printing presses in series is also known, in which the printing cylinders of successive printing units are connected by a single sheet transfer drum.
  • two pairs of gripper systems consisting of two interacting rows of clamping grippers are arranged in the printing cylinder, which follows the sheet transfer drum in the transport direction.
  • Printing cylinders and sheet transfer drums are double in diameter.
  • suction boxes are provided which slightly lift the sheet to be turned from the outer surface of the sheet transfer drum as soon as a row of clamping grippers of the subsequent printing cylinder has gripped the rear edge of the sheet.
  • the sheet to be turned is kept taut by the suction boxes.
  • the suction boxes suck on the non-printed side of the sheet, as soon as the gripper systems of the printing cylinder after the turning process pulls the rear sheet edge from the last suction box, the printed underside of the sheet can either be on the surface of the sheet transfer drum or on the lateral surface of the now Open the sheet transporting printing cylinder, whereby smearing of the printed image is inevitable.
  • the rear edge of the sheet can hardly be transferred without kinking. This would result in permanent deformation of a thicker cardboard box, which cannot be tolerated and which also cause malfunctions.
  • the object of the invention is to provide a convertible high-performance sheet-fed rotary offset printing machine of the type mentioned at the outset for the smudge-free processing of paper up to thick cardboard.
  • Storage drum and turning cylinder preferably have a double diameter.
  • the printing cylinder of which is designed as a storage drum the associated blanket cylinder is expediently parked.
  • At least the sheet guiding surfaces of the printing cylinder immediately following the reversing cylinder are provided with ink-releasing lifts Mistake.
  • These lifts have a structured arch support surface and are made of a wear-resistant, chemically resistant, color-releasing material, such as nickel or chrome.
  • the sheet guiding surfaces of a convertible impression cylinder can be equipped with removable, stable shells.
  • optionally switchable suction chambers connected to a vacuum generator can be provided in the shells, which are connected to the atmosphere via suction holes in the outer surface of the shell and the respective rear area of the sheets of different formats by suction prevent slipping or falling.
  • the printing cylinder when the printing cylinder is designed as a storage drum, instead of a shell, two groups of sheet support segments that can be adjusted to the sheet format to be processed are provided.
  • One group of the sheet support segments can be connected to the gripper bridge for holding the leading edge of the sheet and the other group can be connected to a suction system for holding the trailing edge of the sheet.
  • the arch-carrying diameter of the arch-supporting segments must be identical to the diameter that the shells installed in the pressure cylinder have.
  • the sheet-fed rotary printing machine according to FIG. 1 is provided for five-color face printing or for two-color face and reverse printing. It has five printing units 1-5.
  • the sheet feeder 6 is connected upstream of the pressure value 1. This feeds the sheets taken from a stack 7 to a sheet feed drum 8 which is mounted in the side walls of the printing unit 1. It transfers the sheet to the printing cylinder 9 of the first printing unit, which has a double diameter. Rubber cylinder 10 and plate cylinder 11, on the other hand, have only a simple diameter.
  • the printing cylinder 9 is therefore provided with two sheet guiding surfaces. It transfers the respectively printed sheet to the sheet transfer drum 12 of the printing unit 2.
  • the sheet transfer drum 12 works together with the printing cylinder 13. Both the sheet transfer drum 12 and the printing cylinder 13 are double in diameter.
  • the subsequent printing unit 3 likewise has a sheet transfer drum 12 and, of course, blanket cylinder 10 and plate cylinder 11.
  • the printing cylinder of the printing unit 3, however, is converted to a storage drum 14.
  • the rubber cylinder 10 is set down from the outer surface of the storage drum 14 and the two sheet guiding surfaces of the storage drum 14 mentioned each consist of two groups of arc-supporting segments which can be displaced into one another in a chamber-like manner.
  • a group of these arch support segments is firmly connected to the gripper bridge 15, the other group to the suction system 16.
  • the suction system 16 can be adapted to the sheet format, so that it is always the end of the arch captured and due to its special training causes a tightening of the bow.
  • the printing unit 4 As in the preceding printing units 2 and 3, four cylinders are accommodated in the printing unit 4, namely blanket cylinders 10, plate cylinders 11 and printing cylinders 13 with a double diameter.
  • a turning cylinder 18 is provided instead of the sheet transfer drum 12, a turning cylinder 18 is provided. It is equipped with two pliers gripper systems 19, which, depending on the setting of the five-color sheet-fed rotary printing press, capture either the leading edge of the sheet in the straight printing process or the trailing edge of the sheet in the face and reverse printing processes.
  • the last printing unit 5 has the same cylinder arrangement as printing unit 2, i.e. it has the sheet transfer drum 12 with double diameter and the rubber 10 and plate cylinder 11.
  • the printing unit 5 is followed by the sheet delivery 20, the delivery drum 21 of which is provided with double diameter, and the sheet of printing cylinder 13, which is printed either five times or on both sides of the printing unit 5 takes over.
  • a chain boom 22 conveys the printed sheet onto the delivery stack 23.
  • the sheet-fed rotary printing machine shown in FIG. 1 prints the sheet twice on both the bottom and the top due to the arrangement of the storage drum 14 and the reversing cylinder 18. Due to the chain of the relatively large sheet guide cylinders 9, 12, 13, 14, 18 and 21, this machine can process very thick cardboard, all the more because the gripper systems 19 can grasp the trailing edge of the sheet in such a way that the relatively rigid cardboard does not kink he follows. However, even relatively thin papers can be processed very well, since the suction system 16 of the storage drum 14 tightens these thin sheets and ensures a precise transfer of the trailing edge of the sheet to the gripper systems 19. A special advantage of this machine is that the printing units 2, 3, 4 and 5 can be made absolutely identical in terms of their side frames.
  • the section from FIG. 1 shown in FIG. 2 concerns the three printing units 2 and 4.
  • the formation of all three printing units is the same with one exception.
  • the storage drum 14 has been converted into a pressure cylinder 25.
  • the conversion consists in that instead of the above-mentioned comb-like groups of arch support segments, a stable shell 26 is provided.
  • the outer diameter of both shells 26 corresponds to the diameter of the arch-bearing surface of the arch-support segments removed.
  • the shells 26 are designed to be stable and are attached to the core of the pressure cylinder 25 in an easily removable manner. They can be provided with suction chambers, which can be optionally connected to a vacuum generator, not shown. Suction bores in the outer surface of the shells connect the suction chambers to the atmosphere.
  • the respective sheet guided by the shell 26 can be sucked in its rear region after printing, so that the sheet is prevented from slipping or slipping even when the leading edge of the sheet is taken over by the pliers gripping system 19.
  • the suction system 16 already used in the storage drum 14 can be used to hold the sheet.
  • the rubber cylinder 10 of the printing unit 3 is turned on. In this switch position, it is possible for the sheet-fed rotary printing machine according to FIG. 1 to print a sheet in five colors.
  • the six-color sheet-fed rotary printing press shown in FIG. 3 differs from the previously described only in that two turning devices are provided.
  • the first printing unit 31 has a printing cylinder 9 with a double diameter, a rubber cylinder 10 and a plate cylinder 11 with a single diameter.
  • the feed drum 8 receives the sheets it supplies to the impression cylinder 9 from the sheet feeder 6.
  • the next printing unit 32 is equipped with a normal sheet transfer drum 12, a storage drum 14, the rubber cylinder 10 and the plate cylinder 11. Sheet transfer drum 12 and storage drum 14 have a double diameter.
  • the rubber cylinder 10 is of course turned off.
  • the following printing unit 33 has a turning cylinder 18, a convertible printing cylinder 25 equipped with two shells 26, as well as rubber 10 and plate cylinders 11.
  • the next printing unit 34 has a turning cylinder 18, a printing cylinder 13, both have double diameters and, as usual, rubber cylinders 10 and plate cylinders 11.
  • the last two printing units 35 and 36 are of exactly the same design, namely with an ordinary sheet transfer drum 12, a printing cylinder 13 and rubber 10 and plate cylinder 11.
  • the sheet delivery 20 accordingly corresponds to the embodiment according to FIG. it also has a delivery drum 21 with a double diameter.
  • the single-color printing of one sheet side takes place in the printing unit 31 and the printing sheet 32 is turned in the printing unit 32 due to the arrangement of the storage drum.
  • a four-color counterprint is applied to the sheet surface now on top.
  • the sheet guiding surface of the printing cylinders 25 and 13 of all four printing units 33, 34, 35 and 36 can be provided with ink-releasing elevators, so that smearing of the print applied by the printing unit 31 is prevented.
  • both printing units 32 and 33 can be equipped with printing cylinder 25.
  • the embodiments shown in FIGS. 1 to 3 can also be modified insofar as, for example, impression cylinders 25 and also impression cylinders 13 or sheet transfer drums 12 and 18 have triple diameters and are accordingly provided with three sheet guiding surfaces.
