Definitions

  • the improvement relates to a switching device according to the preamble of claim 1.
  • a switching device is described in DE-AS 2 133 693.
  • turning curves of the turning drum have to be switched on and the gripper opening curves have to be shifted relative to the turning drum in accordance with the changeover to the bow end, or curves with a correspondingly shifted opening point have to be switched on.
  • DE-AS 2 133 693 describes a device for controlling the grips of a sheet transfer and turning drum of a multi-color sheet-fed rotary printing press.
  • the turning curve is disengaged during normal operation of the sheet-fed rotary printing press.
  • the turning curves and the gripper opening curves are slidably mounted and coupled to one another via a linkage. For converting the machine from face printing to face and back printing the linkage is unlocked and moved axially using a handle, so that the turning curve and the gripper opening curves are moved axially at the same time.
  • Such a switchover device has the particular advantage that it is actuated when the operating state is selected at the start of the switchover process and the switchover of the gripper opening and turning curves therefore does not require any further attention from the operating personnel.
  • the switching device is very reliable, since it is also switched depending on the direction from the respective operating state.
  • the switching device is shown in the context of the indicated machine structure.
  • the pneumatic cylinder 1 is provided with a clutch 2. This is attached to a shift hub 4 via a fork 3.
  • the shift hub 4 sits on the shift shaft 5.
  • the shift shaft 5 is axially parallel to a turning drum 6 and a storage drum 7.
  • the pneumatic cylinder 1 is also connected via lines 8 to a pneumatic valve 9.
  • the pneumatic valve 9 has the connection of an air supply 10.
  • the pneumatic valve 9 is connected to a changeover switch 11.
  • the changeover switch 11 generally serves to prepare the sheet-fed rotary printing press for the changeover from the printing mode to the printing mode, and vice versa. Interlocks in the machine, a machine brake and various safety devices are activated for this.
  • the connection to the control of the sheet-fed rotary printing machine is indicated on the changeover switch 11 by a connection 12.
  • FIG. 2 shows the connection of a gripper opening curve 13 to the control shaft 5.
  • a further shift hub 14 is fastened on the shift shaft 5.
  • the tab 15 is connected to the gripper opening curve 13, which is rotatably seated on a shaft part of the turning drum 6.
  • an extension 16 is attached to the shift hub 15.
  • the extension 16 is provided with stop surfaces 17.
  • the stop faces 17 are assigned adjustable end stops 18 which are fastened in the machine frame.
  • FIG. 3 shows the coupling of a turning curve 19 to the control shaft 5.
  • a third switching hub 20 is fastened on the selector shaft 5.
  • a setting slide 21 is articulated on the shift hub 20.
  • the slide valve 21 is therefore to be moved linearly and is secured in position by a spring rod 23 relative to the shift hub 20, the linear movement being made possible, for example, by coupling the shift hub 20 to the slide valve 21 via a shift fork.
  • the turning curve 19 is provided with guide rods 24 which make it axially movable relative to the turning drum 6. At the outer end of the guide rods 24 support rollers 25 are provided, which are supported on the actuating cams 22 on the slide valve 21. The guide rods 24 are pressed against the actuating cams 22 under spring force. By longitudinally displacing the slide valve 21, the turning curve 19 can be brought into connection with cam rollers 26 on the turning drum 6.
  • the switching device works as follows: To switch the sheet-fed rotary printing press from one operating mode to the other, the changeover switch 11 is first actuated. The sheet-fed rotary printing machine is locked and secured. At the same time, however, the pneumatic valve 9 is actuated and, depending on the starting position, the pneumatic cylinder 1 is moved into its other end position. The extension 16 strikes the shift hub 14 with one of its stop surfaces 17 on one of the two end stops 18 depending on the direction of movement. The size of the angle of rotation or the position of the pivoting movement of the control shaft 5 can be changed by adjusting the end stops 18. The rotation of the selector shaft 5 transfers a movement from the selector hubs 14 and 20 to the adjustment of the gripper opening curve 13 and the turning curve 19.
  • the tab 15 transmits a rotary movement to the gripper opening curve 13 while the adjusting slide 21 transmits an axial movement via its adjusting cams 22 to the turning curve 19.
  • the opening time of the grippers on the turning drum 6 is set to the face pressure and at the same time the turning curve 19 is disengaged from the cam rollers 26 or the gripper opening curve 13 is switched to the opening time for the counterpressure operation and the turning curve 19 is brought into engagement with the cam rollers 26 .
  • the assignment of the position of the gripper opening curve 13 can be set as described above. The process takes place without any intervention on the part of the operating personnel and ensures that the curves are assigned for operation in one of the two modes of operation.
  • the arrangement in the manner shown can of course be changed apart from details without touching the essential content of the improvement.
