Definitions

  • Such a device is known from DE-PS 10 94 270.
  • the swivel parts are hinged to the side walls of a machine frame, which is penetrated on one side by a protruding end of the front marker shaft.
  • This protruding end of the front brand shaft carries a cam-controlled lever.
  • the force is applied to pivot the front mark shaft back and forth about its longitudinal axis at one end of the front mark shaft.
  • This can lead to torsional and bending vibrations of the front mark shaft with considerable amplitudes, particularly in the case of high-speed printing presses, so that a perfect contact of a sheet leading edge with the front marks is not guaranteed.
  • the front marks can oscillate locally in and against the feed direction of the sheets to different degrees beyond an alignment position. This may result in the sheet being tilted or in damage to its leading edge.
  • the object of the invention is to design a generic device so that alignment errors and damage to the leading edge of the sheet are kept as small as possible when used on high-speed printing presses.
  • Pivoting devices for pivoting the front mark shaft back and forth generally have a force application point located outside the longitudinal axis of the front mark shaft.
  • such swivel devices In addition to impressing a torque, such swivel devices also transmit lateral forces to the front mark shaft.
  • the cited transverse forces can lead to considerable deflections of the front mark shaft.
  • a disturbing influence of these deflections on the perfect alignment of the sheets on the front marks the flawless transfer of aligned sheets to subsequent sheet transfer means equipped with grippers and careful handling of the leading edge of the sheet can be prevented by supporting the front mark shaft by means of an additional bearing, preferably in the immediate vicinity of the force application point. With this, deflections of the front mark shaft can be counteracted, but such an additional bearing would preclude an adjustment possibility for changing the position of the front mark shaft without further measures.
  • the combination provided according to the invention thus enables the unfavorable effects existing in the direction of a bending of the front mark shaft in addition to the described favorable properties of an attack of the swivel device approximately in the longitudinal center of the front mark shaft, and at the same time maintain a free adjustability of the front mark shaft by means of the swivel parts can.
  • the front marks 1 are rotatably connected to the front mark shaft 2 by means of pins 11. To simplify the illustration, only two of the front brands 1 distributed over the length of the front brand shaft 2 are shown in the drawing.
  • the front brand shaft 2 is freely rotatably supported in each pivot part 4 by means of self-aligning bearings 3, these self-aligning bearings 3 being inserted into an upper end of a respective swivel part 4.
  • Each lower end of the swivel parts 4 is connected via a joint 5 to a fixed crossmember 6, the ends of which are fastened to side walls (not shown).
  • the joints 5 form a common geometric pivot axis 25 for the pivot parts 4 and allow their pivoting in and against the feed direction of the sheets.
  • the respective swivel position of the swivel parts 4 is defined by adjusting means shown in detail in FIG. 2.
  • a further fixed crossbeam 7 is provided which faces the upper ends of the swivel parts 4.
  • One clamping screw 8 passing through this crossmember 7 is screwed into an upper end of a swivel part 4.
  • a spring 9 clamped under the screw head of the tensioning screw 8 and supported against the crossmember 7 presses the respective pivot part 4 in the direction of the crossmember 7 against an adjustable stop which is formed by an adjusting spindle 10 mounted in the crossbar 7.
  • FIG. 1 for the sake of simplicity, only a section of the crossmember 7 opposite the right-hand swivel part 4 in the drawing and, accordingly, only one adjusting spindle 10 is shown.
  • a rocker arm 13 is rotatably connected to the front marker shaft 2 by means of a pin 12. This rocker arm 13 is used to pivot the front mark shaft 2 back and forth about its longitudinal axis and is according to the Invention arranged in the immediate vicinity of an additional support bearing 16 for the front marker shaft 2.
  • the end of the rocker arm 13 facing away from the front marker shaft 2 is articulated to a crank rod 14 of a crank mechanism, not shown in detail, with which the crank rod 14 is moved back and forth in accordance with the double arrow 15 in time with the printing press.
  • the front marker shaft 2 is received in at least one additional support bearing 16, which follows the changes in position of the front marker shaft 2, which can be brought about by pivoting the pivoting parts 4 in the same direction or individually about the joints 5 by means of the adjusting spindles 10.
  • the support bearing 16 receives the front marker shaft 2 in a needle bearing 18 inserted into a bearing lever 17 so that it can rotate freely.
  • the bearing lever 17 is connected on the one hand by means of a further joint 24 to the cross member 6 and on the other hand is fastened to a cross member 19.
  • the joint 24 is formed here, for example, with a further self-aligning bearing, not shown, whose outer ring is aligned with the common geometric pivot axis 25 of the pivot parts 4, and in the inner ring of which a joint pin connected to the bearing lever 17 is inserted, so that the bearing lever 17 also to a limited extent can pivot about an imaginary longitudinal axis of the same.
  • the crossmember 19 extends between the swivel parts 4. Each end of the crossmember 19 is articulated between an upper and a lower end of a swivel part 4.
  • FIG. 3 A corresponding articulated connection is shown in Fig. 3.
  • a self-aligning bearing 20 is used in the swivel parts 4.
  • a pin 21 is inserted, which fits into a respective end bore 22 of the cross member 19 and is secured against this by means of a locking screw 23.
  • the traverse 19 which follows the changes in position of the swivel parts 4 and thus those of the front marker shaft 2 is rigidly connected to the bearing lever 17 via a screw connection 26.
  • the needle bearing 18 inserted in the bearing lever 17 thus follows on the one hand the changes in position of the front mark shaft 2 and at the same time forms an effective support of the front mark shaft 2 against deflections which would otherwise be caused by the attack of the rocker arm 13.
  • the articulated connection between the crank rod 14 and the rocking lever 13 is also designed such that the latter can also pivot to a limited extent about its imaginary longitudinal axis.
