Definitions

  • Sheet turning devices of this type are known from DE-PS 1 262 294 and DE-AS 1 786 371.
  • the object of the invention is to enable sheet registration of print carriers of all thicknesses and lengths up to the highest printing speeds from the preceding printing cylinder in a sheet turning device of the type mentioned above by means of gripping devices.
  • the advantage of the invention is that the security of the register accuracy is increased because mechanical gripper transfers generally take place both in straight printing and in face and back printing.
  • a sheet offset rotary printing machine for optional face and back printing is shown, which works on the principle of the trailing edge application in a known manner.
  • the schematically illustrated two-color printing unit 21 has a double-sized transfer drum or reversing drum 2 between double-sized printing cylinders 1, 3, which are mounted in side stands 11 in a known manner.
  • the sheets 13 to be printed are also fed to the printing cylinder 1 in a known manner and removed from the printing cylinder 3 again.
  • the printing cylinders 1, 3 are each provided with two gripping devices 8, 9 and 23, 24, which are diametrically opposite one another and are used for the transport of the sheet 13 in a controlled manner.
  • Printing cylinders 1, 3 and transfer drum or turning drum 2 are designed for the transport of two sheets 13 on the circumference.
  • the double-sized transfer drum or turning drum 2 has two pairs of gripping systems 4, 6 and 5, 7, which interact and can be pivoted relative to one another.
  • the gripping devices 4, 6 and 5, 7 lie diametrically opposite one another in pairs.
  • an adjustable covering 10 is provided on the printing cylinder 1 placed in front of the turning drum 2 in such a way that gripping of the bow end is made possible.
  • the printing cylinder 1 has a base body 20 which is several millimeters smaller and closed over the entire printing area and on which is covered 10 is a roller shutter 10.1 with an overlying film covering 17, via which the printing cylinder 1 receives its actual diameter or there are several roller shutter strips 10.2 sunk in the circumferential direction as covering 10 in the printing cylinder 1, the surfaces of which coincide with the surface of the printing cylinder and which are covered with a continuous cover plate 31, via which the printing cylinder 1 receives its actual diameter.
  • Suitable as film covering 17 via roller shutters 10.1 is e.g. a film made of fine steel strip, corresponding fabric or the like, which extends over the entire width of the printing cylinder 1 and is 0.2 to 1 mm thick, while the continuous cover plate 31 has a thickness of e.g. Can have 1 mm.
  • the printing cylinder 1 preferably has an outer diameter which is at least 3 mm smaller, so that the gripping devices 4 and 5 can grip the sheet 13 at the end of the sheet when the roller shutter 10.1 is to be used. (Fig. 7) As a result, variable free spaces 26 are created between the gripping devices 5, 8 and 4, 9 for detecting the trailing edge of the sheet, so that the front gripping devices 4 and 5 seen in the direction of rotation of the double-sized transfer drum or reversing drum 2 are used for each format setting can dive into the circumferential path of the double-large impression cylinder 1.
  • roller shutters 10.1 is understood to mean a covering 10 consisting of narrow strips 32 and / or chain links, wire mesh, a special rubber blanket or similar elastic composite 30 over the entire width, which has an almost closed outer surface on the outer diameter of the pressure cylinder, is radially rigid and can be wound up in the circumferential direction.
  • the narrow strips 32 are threaded onto several steel cords 33 and have an almost gap-free surface on the pressure cylinder 1 (FIGS. 6 and 8).
  • a special rubber blanket is e.g. a hard rubber blanket which has a cover layer 53 with inlays 52 and a base layer 54 with notches such that the composite is radially rigid and can be wound onto the printing cylinder 1 in the circumferential direction (FIG. 11).
  • Wire mesh or similar elastic composites 30 of a different type must have comparable properties.
  • both roller shutters 10.1 and also the film coverings 17 and the cover plate 31 can be wound up via roller shutter strips 10.2, depending on the set sheet length, on winding shafts 16 and 18 mounted in the printing cylinder 1.
  • Roughened surfaces 55 secure the position of the roller shutter strips 10.2 on the take-up shafts 18.
  • the take-up shafts 16, 18 are received in end walls 15 of the base body 20.
  • An end member 12 of the roller shutter 10.1 or the cover plate 31 arranged over roller shutter strips 10.2 have a greater width at the end, are mounted on the end face on a pin 27 of the pressure cylinder 1 and can be adjusted and clamped from the outside by means 28, 29 (FIGS. 3 and 9 ).
  • a device 29 In order to be able to make a format setting, a device 29 must be released from its clamped position by means of axially arranged hexagon sockets of the same size and associated hexagon keys in order to be able to move the covering 10 on the base body 20 of the printing cylinder 1 in the circumferential direction.
  • the device 28 required for this consists of an adjusting shaft 34 which is integrated in the pin 27 of the pressure cylinder 1.
  • An adjusting pinion 35 is fastened on the adjusting shaft 34, which is in operative connection with a further adjusting pinion 43 via a gear wheel 36 mounted in the pressure cylinder 1 and which is attached to an adjusting shaft 41 mounted in the end walls 15 (FIGS. 3, 4, 9).
  • suction plates 19 which extend in a row in the axial direction of the pressure cylinder 1 and which are supplied with suction air through a channel 25 (FIGS. 3, 6 to 8). .
  • suction plates 10.2 are integrated at their ends in a row extending in the axial direction of the pressure cylinder 1 suction surfaces, which are supplied with suction air by a suction device 22 ( Figures 9 and 10).
  • the outer suction plates 19 can be closed if the sheet format of a sheet 13 is narrower than the covering 10, ie the sheet transport surface.
  • the suction device 22 is constructed in a manner known per se in the form of a rake Division of the roller shutter strips 10.2 in the base body 20 of the printing cylinder 1 in front and ends with the surface of the cover plate 31 with suction surfaces and suction bores, not shown, in one plane.
  • a suction air supply 40 is provided, from which the suction air is guided into the interior of the base body 20.
  • the suction air supply 40 is connected to the side parts 14 of the continuous cover plate 31 which can be rotated on the base body 20 of the pressure cylinder 1 in front and, as can be seen from FIG. 10, can slide circularly in an elongated hole 38 in the end walls 15 when the format is changed.
  • roller shutters 10.1 or roller shutter strips 10.2 are ground on the printing cylinder 1.
  • roller shutters 10.1 with foil coverings 17 or roller shutter strips 10.2 with cover plate 31 are preferably connected at the end of the covering 10 and the covering 10 is e.g. can also be tensioned by torsion springs on the winding shafts 16, 18. This always ensures a secure position of the covering 10 guided loosely on the base body 20 of the printing cylinder 1.
  • a scraper 37 removes deposits on the base body 20.
  • both one-sided printing of the sheet 13 with two colors and the turning of the sheet 13 are functionally related to the printing cylinder 1 in front and thus double-sided printing the arch 13 possible.
  • the second printing unit is then used as an impression printing unit.
  • the sheet 13 is transported in a known manner by transfer, for example, from the gripping devices 9 of the printing cylinder 1 to the gripping devices 6 of the transfer drum 2 and from there to the gripping devices 24 of the printing cylinder 3 and is therefore not described in more detail (see FIG 1).
  • the sheet 13 was guided, for example, by the gripping devices 9 of the printing cylinder 1 in front of the tangent point in a first phase and the sheet end has reached the tangent point.
  • the end of the sheet is gripped by the gripping devices 5, after which the gripping devices 9 release the sheet.
  • Due to the covering 10 according to the invention set on the arch end unhindered gripping under the arch end on the upstream pressure cylinder 1 is possible by means of mechanical gripper systems.
  • the gripping devices 5 and the gripping devices 7 are swung during the further rotation of the pressure cylinders 1, 3 and the turning drum 2 onto the center of the turning drum 2 and towards one another in a manner known per se.
  • the sheet 13 is transferred from the gripping devices 5 to the gripping devices 7 at the end of the sheet and is conveyed by the gripping devices 7 in a further phase while simultaneously pivoting the gripping devices 7 outward to the printing line.
  • the sheet 13 is now held in register, lubrication-free and wrinkle-free and is transferred from the gripping devices 7 with the trailing edge first to the gripping devices 23 of the printing cylinder 3.
  • the next sheets are transferred in the same way, the printing cylinders 1, 3 and the turning drum 2 being set up for the transport of two sheets on the circumference, as can be seen from the drawing.
