Definitions

  • the invention is based on a sheet-fed rotary printing machine in series design of the printing units for processing both paper and cardboard in one-sided multi-color printing or surface and reverse printing with at least one turning device, with each printing unit having a printing cylinder and a transfer drum in addition to a plate and a rubber cylinder has at least twice the diameter.
  • a multi-color sheet-fed rotary printing press of the type outlined above is already known from DE-OS 24 52 167.
  • 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 rotational 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; however, since removing the trailing edge from the smooth counter-pressure surface of the impression cylinder has to be done by means of a suction system, a buckling of the rear sheet area is inevitable during the transfer process of the trailing edge of the sheet to the gripper system of the turning cylinder, despite the use of a double rocker, whereby the processing of thick cardboard, if at all, only possible in the low speed areas would.
  • the aforementioned kinking of the trailing edge of the sheet in fact causes the sheet to be torn off from the suction system due to the stiffness of the carton, particularly with higher machine outputs.
  • pressure-free spaces for pressure segments must be available with this turning system.
  • 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 transfer drum.
  • two pairs of gripper systems consisting of two interacting rows of clamping grippers are arranged in the pressure cylinder, which follow the transfer drum in the transport direction.
  • Printing cylinder and transfer drum are double in diameter.
  • suction boxes are provided which slightly lift the sheet to be turned from the lateral surface of the 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 now rear sheet edge from the last suction box, the printed underside of the sheet can either on the surface of the transfer drum or on the outer surface of the now Transport the sheet open the printing cylinder, whereby smearing of the printed image is unavoidable.
  • the trailing edge of the sheet can hardly be transferred without kinking with the two rows of grippers that come into action when the sheet is turned. This would give a thicker box permanent deformation that cannot be tolerated.
  • bent cardboard edges cause malfunctions by hitting the following gripper edges and preventing the cardboard from being correctly gripped.
  • DE-OS 26 39 900 a sheet-fed rotary printing press in unit construction with a device for optional face and back printing is known, in which a block designed as an independent unit is arranged between the similar printing units, which has a transfer drum and one subordinate turning cylinder of the aforementioned type.
  • the transfer drum works with one or two drying devices.
  • the sheet is obviously also sucked in by the gripper devices of the turning cylinder on the lateral surface of the transfer drum and transferred to other gripper devices for the purpose of turning.
  • a kinking of stiffer cardboard edges cannot be avoided. You should also tear off the cardboard from the suction systems.
  • the drying facilities also represent a considerable effort. They require a lot of energy.
  • a particular disadvantage of the drying devices is that they are used in the middle of the printing process and tend to heat up the associated cylinder. Excessive heating can then result in tensions in large-area printed sheets, which can lead to registration errors, especially with perfecting 1/4 after printing the monochrome printing and before Applying the multicolour fine print the drying takes place.
  • the object of the invention is to provide a high-performance sheet-fed rotary printing machine for single-sided multi-color printing and for face and back printing, which ensures smudge-free and damage-free, register-containing processing of paper up to thick cardboard.
  • the relatively large diameters of all sheet-guiding cylinders and drums make it easier to transport the sheets with register.
  • the use of pliers grippers in cooperation with the storage drum and the hook grippers of the impression cylinder following the turning cylinder enable sheet transfer during the turning process without kinking or damaging the sheet edge. Waste can be avoided in this way. Stops are also switched off due to bent sheet edges.
  • the precautions for the smear-free transport of the sheets finally make a drying device that consumes a lot of energy and possibly deform the sheets superfluous.
  • a simple base frame for holding a transfer drum and a storage drum does not mean a particularly great outlay if the transfer drum and storage drum as well as the reversing cylinder are used in other types of series machines anyway and can be taken over without further ado.
  • the counter-pressure surfaces of the printing cylinders which are connected downstream of the turning cylinder, are provided with color-repellent jacket surfaces, for example in the form of elevators.
  • Such lifts are disclosed in DE 24 46 188 and DE-OS 29 16 505.
  • the sheet guiding surfaces of the transfer drums and the reversing cylinder can either be provided with closed outer surfaces that are ready to give off paint, or can be equipped with rods and supporting elements, for example rolls.
  • rods and supporting elements for example rolls.
  • a particularly favorable further development of the invention consists in that the transfer drum and the turning cylinder are provided with removable shells which form the sheet guiding surfaces.
  • These trays are used when processing paper, especially lighter papers.
  • the shells can be removed from the transfer drums and turning cylinders, because there is no need for sheet guiding elements.
  • This has the advantage that the outer surfaces of the shells which are ready to give off color do not need to be washed frequently.
  • the optional use of these trays enables the printer to design the most favorable makeready times.
  • FIG. 1 shows a section of a board machine for single-sided multi-color printing, convertible to face and reverse printing.
  • the feeder and delivery arm are not shown in the figure.
  • the printing unit 1 is also only partially shown. His pressure cylinder 2 passes the sheet 3 by means of its normal clamping gripper 4 to the subsequent transfer drum 5. Printing cylinder 2 and transfer drum 5 have a double diameter.
  • the transfer drum 5 is mounted in a simple base frame 6, which is also used to hold a storage drum 7.
  • the storage drum 7 takes over the bow from the transfer drum 5 with its hook gripper rows 8.
  • the sheet 3 taken over is tightened on the storage drum 7 by means of suction cups 9, so that the rear sheet edge assumes a predetermined position corresponding to the aligned front edge.
  • the simple base frame 6 is followed by a printing unit 10.
  • This essentially consists of the plate cylinder 11 and blanket cylinder 12, both with a single diameter, and from the printing cylinder 13 and the reversing cylinder 14, the latter two with a double diameter.
  • the turning cylinder 14 has two diametrically opposite rows of pliers grippers 15. Furthermore, the sheet guiding surfaces of the turning cylinder 14 are formed by two removable shells 16, which are provided with an elevator that is easy to dispense. These trays are used when processing paper. However, they have to be washed frequently so that their outer surfaces retain the paint-dispensing properties to a sufficient extent. When processing stiffer papers or even cardboard, the trays are removed because special sheet guiding surfaces are not necessary. Of course, this also eliminates the need to wash the jacket surfaces. As a result, the downtimes of the board machine are considerably reduced.
  • the pressure cylinder 13 adjoining the turning cylinder 14 likewise has specially designed hook grippers 8, just like the storage drum 7, so that the sheet transfer from the turning cylinder 14 by means of the gripper 15 to the printing cylinder 13 is possible.
  • the pincer grippers 15 take over the sheets on their front edge from the hook grippers 8 of the storage drum 7. If the perfecting method is used, the sheet is turned and the pliers grippers grip the rear edge of the sheet 3 which is guided past the turning cylinder 14 on the storage drum 7 and which, as already mentioned above, is tightened by the suction cups 9.
  • the printing unit 10 adjoining printing unit 17 corresponds in its structure completely to printing unit 1.
  • the adjoining printing unit 18, which is only shown to a small extent, has the normal structure, which consists in that in addition to plate cylinder 11, rubber cylinder 12 and Printing cylinder 2 with normal clamp gripper rows 4, a transfer drum 19 with a triple diameter is provided.
  • the normal structure which consists in that in addition to plate cylinder 11, rubber cylinder 12 and Printing cylinder 2 with normal clamp gripper rows 4, a transfer drum 19 with a triple diameter is provided.
  • three rows of normal clamping grippers 4 are arranged symmetrically on the circumference of the transfer drum 19.
  • the printing unit 18 connected to the printing unit 17 with a normal structure consequently also has a transfer drum 19 with a triple diameter.
  • the board machine can apply four-color printing on sheets as well as on rigid cardboard.
  • two-sided prints of various types can be produced. For example, if the board machine had six printing units and the third printing unit corresponded to printing unit 10, a two-fold could be on one side of the box a four-color print is applied on the opposite side.
  • the particular advantage of the described cardboard machine according to the invention is that it processes both paper and thick cardboard in a register-free and lubrication-free manner in the entire format range even at high printing speeds. If necessary, two turning devices can of course also be provided.
