Definitions

  • the invention relates to a sheet transfer cylinder for sheet-fed rotary printing presses according to the preamble of patent claim 1.
  • the paper sheet is transported from one printing unit to another, for example by means of a generic sheet transfer cylinder.
  • the sheet of paper lies with the printed side on the outer surface of the sheet transfer cylinder, which is why it is possible to smear the still wet print.
  • the US P S is to be called 1,358,843.
  • the arch-bearing surface consists of four, each across the width of the arch transfer cylinder-extending segments that are radially adjustable via an adjusting mechanism. The adjustment is made for all segments at the same time with a hand lever to be attached to the front.
  • the design effort is relatively high, since in addition to the entire adjusting mechanism, several additional plungers are required as guide means for each segment in order to prevent any transverse movement in the longitudinal direction of the cylinder in addition to the radial movement.
  • Another disadvantage is that the radial adjustment can only be done in stages. Neither is the necessity taken into account to immerse each segment in the sheet transfer cylinder to different depths, since, for example, the end of the paper sheet flutters more than the sheet leading edge held by grippers.
  • the sheet transfer cylinder according to the invention has further favorable properties, which result from the following description of the figures and the subordinate character sayings that claim advantageous embodiments, can be derived.
  • a sheet guide cylinder in multi-color sheet-fed rotary printing presses for face or face printing is already known per se from DD-PS 76 684, in which guide segments located on its circumference are arranged to be radially movable and a parallel rocker is provided for the radial movement of the guide segments.
  • the cam-controlled articulated mechanism has a further vibrating parallel crank gear on the oscillating shafts, in order to ensure the positive running when the cam-controlled circular eccentrics are moved out of their extended position.
  • FIG. 1 shows a sheet transfer cylinder 1 with this associated printing cylinders 2, 3 of an upstream or downstream printing unit.
  • three sheet support segments 5 are provided which are distributed uniformly over the circumference and extend over the length of the sheet transfer cylinder 1, each of which can carry a sheet 4.
  • the gripper bridges 6 each associated with the sheet support segments 5 with grippers 7 and gripper supports 8 acting in the usual way hold each sheet 4 firmly.
  • the gripper bridges 6 are fastened by means of fastening means 9 to corresponding webs 11 arranged on an inner cylinder 10.
  • a toothed disk 20, 21 is rotatably mounted on each bearing journal 16, 17 and secured axially by means of a locking ring 22, 23.
  • a pinion 24, 25 engages, which is in each case rotatably arranged on an adjusting shaft 26 extending over the length of the sheet transfer cylinder 1, which in turn rotates itself at corresponding bearing points 27 - 29 of the inner cylinder 10 supports.
  • a worm wheel 30 is mounted on the actuating shaft 26 in the area of the sheet transfer cylinder 1.
  • a worm 31 engages in this, in the extension of which an adjusting bolt 32 is provided, the upper head end 33 of which can be rotated by means of appropriate working means (eg socket wrench) and which can be locked by means of the locking screw 73.
  • worm 31 and adjusting bolt 32 are mounted in a holder 34 fastened to one of the three gripper bridges 6.
  • a coupling rod 39, 40 is articulated at each articulation point 37, 38 of each toothed disc 20, 21, the other articulation point 41, 42 of which, both with the area of each sheet support segment 5 that supports the trailing edge 4.1, and with a rocker 43, 44 in Connection is established, which in turn is fastened to an articulation point 45, 46 which is fixed to the frame and is located on an extension 47 of the web 11.
  • This gear mechanism is thus designed as an oscillating four-link coupling gear, the drive rocker being determined by the radial distance (from the cylinder center line 72) of the articulation point 37, 38 of the coupling rod 39, 40 on the toothed disk 20, 21.
  • each sheet support segment 5 which carries the sheet leading edge 4.2 has a further articulation point 48, 49 for a further rocker 50, 51 which is rotatably mounted on an extension 52, 53 fixed to the frame and which is fastened to the gripper pad 8.
  • the bearing points described above are formed by appropriately arranged bearing bolts.
  • the radial adjustment path 60, 61 over the circumferential surface of each sheet support segment 5 differs, namely in the area of the sheet trailing edge 4.1 larger than in the area of the sheet leading edge 4.2.
  • FIG. 4 shows a further embodiment of a sheet transfer cylinder 62 according to the invention. Only the areas of each of the three sheet support segments 63 which support the sheet trailing edge 4.1 are radially adjustable.
  • the coupling rod 39, 40 which is articulated on the toothed disc 20, 21 in accordance with the first embodiment on both end faces 12, 13 of the sheet transfer cylinder 62, is in turn connected to the sheet support segment 63 at the articulation point 37, 38.
  • the area of the sheet support segment 63 which carries the sheet leading edge 4.2 is directly connected at the articulation point 64 to a web 65 of the gripper pad 8 which is fixed to the frame.
  • the sheet support segments 63 can be brought into the position shown in broken lines in FIG. 4.
  • the system is designed as a four-link oscillating coupling gear, the drive rocker again being determined by the radial distance (from the cylinder center line 72) of the articulation point 37, 38 of the coupling rod 39, 40 on the toothed disk 20, 21.
  • the output rocker arm is itself formed by the sheet support segments 63.
  • the oscillating four-link coupling gears used on both end faces 12, 13 of the bow transfer cylinder 67 are each formed by the bow support segment 66 of the bow transfer cylinder 67, which represents the link, to which the driving toothed disk 20 and a driven rocker arm mounted on the articulation point 70 at the articulation points 68, 69 71 attack.
  • the gear train 20, 21, 24, 25, 30, 31 with a subsequent coupling gear thus permits simultaneous and stepless radial adjustability of the sheet support segments in all embodiments, a rapid adjustment to the respective requirements being possible in a simple manner.
  • the arch transfer cylinder which is adjustable according to the invention, is therefore characterized by a high degree of flexibility, it being additionally conceivable to take the appropriate precautions during its manufacture (e.g., alternative bores for pivot pins for each articulation point). Different pivot points could thus be placed elsewhere, so that the transmission link lengths can be changed, which in turn leads to a change in the coupling curves of the individual coupling links, in order to thereby adapt the setting range of the radial adjustment of the sheet support segments to the given requirements.
  • the radial adjustment could, as described above, be carried out manually by a socket wrench or controlled by a motor, hydraulically or pneumatically.
  • the use on other multiple drums (double, quadruple) is also conceivable and is within the scope of the invention.
