  • the wheel set consisting of the type wheels 19 and the friction disks 22 placed therebetween, shown as a unit in FIG. 3, is placed on the shaft 20.
  • the axial pressure which compresses the wheelset, is achieved by spring washers 26 and 27 on both sides, which are placed between respective washers, the outer of which can be, for example, a retaining ring which is held in an annular groove in the shaft 20.
  • the wheel set is preloaded by the spring washers 26, 27. It can be closed off by means of caps 28 if necessary.

  • the toothed segment 34 extends over a circumferential angle, for example less than 160 °, for example in the range from 80 ° to 110 °. Only for the time during which the drive gear 33 is in engagement with the toothed segment 34 is the drive of the printing unit 11 rotating. This time is available as a setting time for the individual type wheels 19 of each wheel set.

In addition, this ensures a defined tooth engagement of the drive gear 33 in the toothed segment 34.
  • the eccentric projection 35 and the track 36, in particular groove 37 achieve a soft acceleration of the drive shaft 32 and thus of the entire wheel set driven above it. This acceleration when driving the wheelset eliminates, or at least considerably reduces, impacts, shocks and the like, abrupt loads at the beginning of the toothing engagement, which lead to damage and excessive wear. A soft, shock-free start of the drive is achieved.
  • the path 36 extends over a circumferential angle which is, for example, greater than 200 ° and in particular, for example, is in the range from 250 ° to 280 °.

  • the path 36 for example the groove 37, runs essentially on the pitch circle of the drive gear 33 or the toothed segment 34, the end section 38 extending outward at the end of the path 36. This end section 38 causes the explained acceleration of the drive shaft 32 and thus represents an acceleration section.
  • a radial starting section 39 is provided, which merges radially from the inside into the web 36, at least slightly, and thus ensures that the projection 35 runs well into the web 36 when the drive gear 33 at the end of the toothed segment 34 disengaged from this.
  • the web 36, in particular groove 37 contains an inlet slot 40 which is open radially outwards for the insertion of the eccentric projection 35 into the groove 37.
  • the drive of the wheel set, in particular the shaft 20, takes place from the drive shaft 32 via a transmission gear 41 which, for example, causes a translation into slow speed.
  • the transmission gear 41 consists in particular of a planetary gear.
  • the drive shaft 32 is coupled to the shaft 20 to be driven via the transmission gear 41.
  • the shaft 20 is designed as a hollow shaft. As a result, the drive shaft 32 can run coaxially with the hollow shaft 20. This saves space.
  • the transmission gear 41 in particular planetary gear, is arranged on one end of the drive shaft 32 and on the one opposite the end carrying the drive gear 33.
  • the planetary gear has a ring gear 42 held on the printing unit 11, for example its housing 9, in a rotationally fixed manner and, as a sun gear, a drive pinion 43 non-rotatably connected to the drive shaft 32, with which the planet gears 44 are engaged, which in turn are rotatably mounted on the shaft 20, for example by means of indicated bearing bolts 45.
  • the transmission gear 41 and the drive for the shaft 20 as a whole can be designed such that it is rotated by more than 360 ° C circumferential angle so that the highest possible machine speeds can be achieved.
  • the shaft 20 and the drive shaft 32 can be supported by means of plain bearings.
  • the housing 9 can be divided be, whereby a disassembly of the complete wheel set in the axial direction is possible in a simple manner.
  • the arrangement can be chosen so that the drive shaft 32 can be pulled out of the transmission gear 41 in Fig. 6 to the left. This is achieved in that the drive pinion 43 has a smaller diameter than the drive shaft 32.
  • the transmission gear 41 can remain connected to the right wall of the housing 9 in FIG. 6 even after the wheel set has been removed.
  • the circumferential angular extent of the toothed segment 34 is dimensioned such that the type wheels 19 of each printing unit 11 are only driven for a predetermined setting time, the shaft 20 being rotated by more than 360 °, as already explained.
  • each pawl 30 can be held in its release position (FIG. 5, left) and out of engagement with the type wheel 19 by means of the respective actuator 31.
  • the respectively assigned actuator 31, in particular the electromagnet can be activated, in particular switched on, so that the pawl 30 is held in this release position by means of the actuator 31.
  • the actuator 31 can also be controlled into a position releasing the pawl 30, in which case the released pawl can be pushed into its blocking position by the force of a spring 46 acting on it, which is shown on the right in FIG. 5.
  • the actuators 31, in particular electromagnets are only used as holding magnets.
  • the respective spring 46 is received in a receptacle 47 of the housing 9 and is supported on the pawl 30 with its end located at the bottom in FIG. 5.
  • the preload of the Spring 46 can be adjustable.
  • the spring 46 is designed as a compression spring. Because the respective actuator 31, in particular the electromagnet, only serves as a holding magnet and each pawl 30 can be pushed into its locking position (FIG. 5, right) by means of the spring 46, each type wheel 19 is blocked by the pawl 30 in the de-energized state.
  • the design makes it possible to use strong springs 46. This allows large forces to be applied to transfer each pawl 30 into the locked position.
  • the actuator 31, in particular an electromagnet, enables a large magnetic holding force.
  • the release position of the pawl 30 is guaranteed not only with a small air gap but also with a larger air gap in the area of the electromagnet. It is possible, when activating the actuator 31, in particular the electromagnet, to pull the respective pawl 30 fully against the stop.

  • the stationary disk 14 has an approximately circular cam track 51, for example groove 52, which is assigned to a plurality of circumferential printing units 11a to 11h which are arranged in succession in the circumferential direction, and with which the projection 50 constantly rotates during rotation Intervention stands.
  • the next following disc 18 (FIG. 2) at a distance from the disc 14 is provided with a corresponding cam track 51, in particular groove 52.
  • This cam track 51 in particular groove 52, has an arc section 53 deviating from the circular shape on the circumferential area, which precedes the start of the setting time of the type wheels 19.
  • the arc section 53 together with the eccentric projection 50, controls a lifting movement for the pawls 30 of the respective printing unit 11.
  • the eccentric projection 50 consists e.g. from a roll.
  • the cam track 51, in particular groove 52 has an inlet 54 which is open radially outwards for the insertion of the projection 50, in particular the roller, into the cam track 51.

  • Such a drive device is not only simple and inexpensive but also space-saving and has the particular advantage that no drive motor is necessary and large torques and speeds can be achieved, a drive of z. B. up to 20 printing units 11a to 11h is possible with these advantages.
  • the fact that high torques and high speeds can be achieved results in greater safety because it is possible to work with larger forces. These greater forces are thus applied in a simple and space-saving manner by this drive device. High speeds of up to 10,000 rpm can be achieved.

There is therefore almost no play between a tooth gap 56 and the locking tooth 55 of the pawl 30 engaging therein. The respective type wheel 19 is thus locked in both directions of rotation. Any bouncing back of the type wheel 19 when stopping is thus also prevented.
  • the teeth 57 of the locking device 58 are approximately designed in a side view corresponding to the teeth of a circular saw blade, which can best be seen from FIG. 4.
