Definitions

  • the invention relates to a device for changing over a gripper system in a turning drum of a sheet-fed press, which can be operated either in straight printing or perfecting and on which the gripper system must be changed in mode change from Perfecting to perfecting and vice versa.
  • a changeover device for the oscillating shaft - gripper system is known.
  • a pinion is rotatably mounted axially displaceable on the oscillating shaft - gripper system. Due to the axial displacement of the pinion of this is with a drive gear in the operating mode perfecting in or in the mode Perfecting disengaged, so that the oscillating shaft - gripper system rotatably rotatably moves in perfecting pressure and rotatively fixed in Perfecting.
  • the axial displacement of the pinion is initiated via a pneumatic cylinder which actuates the pinion on the shift rod via a shift rod, a clutch and a sliding piece.
  • a pneumatic cylinder which actuates the pinion on the shift rod via a shift rod, a clutch and a sliding piece.
  • the disadvantage of this is that the reached position must be forcibly secured during axial movement of the adjusting elements. This can be done for example by a constant admission of the pneumatic cylinder.
  • this device has an additional locking gear for the ossifugde movement of the oscillating waves in Perfecting.
  • the blocking gear is driven by a further pneumatic cylinder.
  • the switching or blocking function of the gripper oscillation shaft is carried out by a control cylinder.
  • the actuating cylinder acts simultaneously on the shift and lock gear.
  • the manual transmission is operated via the actuating cylinder, the shift fork and the role of the shift fork, wherein the roller runs in the curved path.
  • These elements act perpendicular to the switching direction, so that no restoring forces from the drive of the lock gear act on the lock gear.
  • the switching position is self-locking. A symmetrical force is ensured by the shift fork, whose rollers run offset by 180 ° in two parallel cam tracks of the switching cam.
  • Fig. 1 shows a side view of a turning drum 1 in a sheet-fed rotary printing machine with the upstream and downstream pressure cylinders 31; 32.
  • the turning drum 1 is equipped with a gripper system 6 and with a suction system 9, which is effective only in perfecting.
  • a beater 1 is known and not the subject of the invention.
  • Fig. 2 shows the turning drum 1 half-sided and partly as a section.
  • the turning drum 1 is rotatably mounted with its axis in the side wall 3.
  • a gripper rocking shaft 5 is arranged rotatably.
  • On the gripper rocker shaft 5 sit firmly the gripper shaft holder 7, in which the gripper shaft 8 is rotatably mounted.
  • On the gripper shaft 8 firmly sits the gripper tongue 10, of which over the width of the gripper shaft 8 more are provided.
  • the drive of the gripper shaft 8 and thus the gripper tongue 10 is not shown.
  • the gripper tongue 11 corresponding to the gripper tongue 10 is fixedly assigned to the gripper oscillation shaft 5.
  • a switching cam 12 is further mounted with an annular groove 13 axially displaceable.
  • the switching cam 12 has two parallel curved paths offset by 180 degrees.
  • the annular groove 13 is associated with a shift rod 14 which is axially displaceable in a longitudinal groove 38 and engages with its other end in a shift pinion 15 which is mounted axially displaceably on the gripper shaft 5.
  • the shift pinion 15 engages in a toothed roller lever 16, the cam roller 17 is associated with a control cam 18 which is fixedly arranged on the side wall 3.
  • the switching pinion 15 is rotatably mounted on the gripper rocker shaft 5 by a feather key 37.
  • the roller lever 16 is rotatably supported in the side plate 4 and spring-loaded by a torsion bar spring 19. Fixed to the axis 2, a control cylinder 20 and a bearing block 21 are also stored. On the piston rod 22 of the adjusting cylinder 20, a 12 shift fork 23 is arranged. At the end of the shift fork 23, a roller 24 is provided, which runs in the curved path 25 of the Wegkurve12. At the switching cam 12, a rotation lock 26 is further arranged, which is engageable with a fixed stop 36 on the side window 4 in engagement.
  • the actuating cylinder 20 is designed as a pneumatic cylinder, which is acted upon via the pneumatic line 35.
  • a shift pin 27 is connected (see Fig. 2 and Fig. 3), which engages with its other end in a coupling 28, which in turn is rotatably connected via a second shift pin 29 with a pawl 30.
  • the pawl 30 is pivotally mounted on the bearing block 21.
  • a locking roller 33 is provided, which can be assigned to a locking lever 34.
  • the locking lever 34 is fixedly arranged on the gripper rocker shaft 5.
  • the shift cam 12, the shift rod 14 and the shift pinion 15 form a transmission 12, 14, 15, which is actuated via the actuating cylinder 20, the shift fork 23 and the roller 24.
  • the pawl 30, the locking roller 33 and the locking lever 34 form a locking gear 30, 33, 34, which is actuated via the actuating cylinder 20, the shift fork 23 and the shift pin 27, 29 and the coupling 28.
  • positions of the same elements in straight printing with S and in perfecting with SW are designated.
  • the mode of operation of the changeover device is the following:
  • the locking roller 33 of the pawl 30 abuts the locking lever 34.
  • the gripper oscillation shaft 5 is locked.
  • the actuating cylinder 20 is driven, the shift fork 23 with the roller 24 moves upward, the rollers 24 in the cam track 25 of the cam 12 run and the switching cam 12 (Fig ) move to the left.
  • the shift pinion 15 is brought into engagement with the toothed roller lever 16 via the shift rod 14 so that the gripper shaft 5 can be moved in an oscillating manner in accordance with the curve law of the control cam 18.
  • the shift fork 23 is located in the position shown in FIG. 3 as a solid line position.
  • the switching cam 12 is secured against rotation by the stop 36 on the side window 4 and the rotation lock 26 during the machine run in straight printing and perfecting with respect to the turning drum 1.
