Definitions

  • the invention relates to a device for moving shafts and bearing blocks mounted on slides in slide guides, preferably the bearing blocks of format cylinders and inking rollers of a printing unit in slide guides of the inking unit consoles of a multicolour rotary printing press, with spindle drives driven by electric motors, preferably stepper motors.
  • Such a device for moving the bearing blocks of a forme cylinder and an inking roller of a flexographic printing machine is known for example from DE-PS 29 41 521.
  • the carriages bearing the bearing blocks of the format cylinder are guided in carriage guides of the inking unit consoles and provided with their own spindle drives, and the carriages of the format cylinders are provided with further carriage guides for the bearing blocks of the inking roller carriages, which in turn have their own spindle drives.
  • This known device works satisfactorily per se, but it is because of the additional slides guided in slide guides, which in turn have slide guides for slides that can be moved on them, relatively expensive.
  • FR-PS 669 672 is a printing press with several printing units known in which each format cylinder and each inking unit assigned to it are arranged displaceably on a common guide tube via guide bushings and can be moved by a single spindle provided with a drive.
  • Each inking unit consists of an endless inking ribbon assigned to each format cylinder, which rotates over four guide rollers.
  • the spindle is provided with different pitches, the spindle section moving the inking unit having a larger pitch than the spindle section assigned to the format cylinder, so that when the spindle rotates, this Inking unit runs larger distances than the bearings of the format cylinder.
  • a disadvantage of this known arrangement is that the format cylinder and the printing unit cannot be moved independently of one another, but instead execute both relative movements when the spindle is driven, which are fixed to one another.
  • the object of the invention is to provide a device of the type specified at the outset, with which shafts and in particular format cylinders and the inking rollers associated therewith can be adjusted independently of one another and, for example, to an impression cylinder.
  • this object is achieved in a device of the generic type in that a spindle is rotatably mounted parallel to a single slide guide in the machine frame or on the inking unit console and is provided with a drive, and that on the spindle a non-rotatable and axially immovable with a bearing block or a spindle nut connected to a slide and at least one further spindle nut are attached, which is rotatably but axially immovably connected to at least one further bearing block or its slide and is provided with its own rotary drive.
  • the device according to the invention has a relatively simple structure, since only a single spindle is provided for moving a plurality of shafts or cylinders.
  • a spindle nut In order to be able to carry out several adjusting movements independently of one another with this single spindle, a spindle nut is firmly connected to a slide or bearing block and at least one further is rotatable relative to the adjusting bearing block, so that an adjusting movement can be achieved by rotating this spindle nut via its own drive, which is independent of the actuating movement of the first bearing block.
  • the rotatable spindle nuts have to compensate for the rotations of the spindle by means of corresponding additional rotations if, despite the rotation of the spindle, no adjustment or a specific adjustment is desired.
  • Rotations of the spindle nuts rotatably mounted in slides, which compensate for superimposed rotations of the spindle can be controlled by controllable motors, for example stepper motors, and microprocessor controls easily realized.
  • the device is only to perform the actuating movements of a format cylinder and an inking roller relative to one another and to an impression cylinder, only a total of two spindle nuts need to be arranged on the spindle, which are assigned to two bearing blocks.
  • a spindle is held in a rotationally fixed and axially immovable manner parallel to a single slide guide in the machine frame or on the inking unit console and that at least two spindle nuts are placed on the spindle, which are each rotatably but axially immovably connected to a bearing block or the carriage carrying it and each provided with its own rotary drive. Since the spindle is held rigidly in this embodiment, the drives of the spindle nuts do not need to take rotations of the spindle into account and do not have to compensate for them. In turn, more than two spindle nuts can be placed on the spindle, but only two spindle nuts are required if the actuating movements of a format cylinder and an inking roller are to be controlled relative to one another and relative to an impression cylinder.
  • the spindle nuts which are rotatable relative to the bearing blocks, are expediently held in bushings which are rotatably mounted in the bearing blocks.
  • the bushings can be provided with these extending sleeves, on which drive gearwheels are attached.
  • These drive gearwheels can be driven via belt drives with the output gearwheels of the electric motors or the stepper motors or the reduction gear driven by them.
  • the bearing blocks on each side of the shafts or the format and application rollers are assigned their own spindle drives, so that if the drives are appropriately controlled, any inclined positions of the shaft and / or rollers can also be achieved or compensated for.
  • the flexographic printing press 1 shown in FIG. 1 has a central impression cylinder 2, to which a total of eight printing units 3 are assigned.
  • Each of these inking units 3 has an inking unit console 4, with which two bearing blocks 5 and 6 are firmly connected, for example by means of screws.
  • a spindle 7 is rotatably supported in the bearing blocks 5 and 6 (FIG. 2).
  • a gear wheel 8 is wedged onto its left end, which is connected via a toothed belt 9 to the pinion 10 of a stepping motor 11.
  • the latter is also connected to the bearing block 5.
  • a linear guide 12 fixed to the inking unit console is provided, on which two slides 13 and 14 rest.
  • Bearing housings 15 and 16 are firmly connected to the slides 13 and 14, an anilox roller 17 being mounted in the bearing housing 15 and the corresponding format cylinder 18 being drivably mounted in the bearing housing 16 in a manner not shown. Both housings 15 and 16 each have a stepped bore 19 and 20 which are aligned with one another. The spindle 7 is passed through these two bores 19 and 20. As can be seen from FIG. 2, a bushing 21 is firmly inserted in the part with a larger diameter of the bore 19, the bushing 21 having a hollow cylindrical recess 22 in which a spindle nut 23 is mounted, which is immovable via a feather key 24 in the Socket 21 is held. When the motor 11 is actuated, the bearing housing 15 is accordingly moved back and forth depending on the direction of rotation of the motor 11, the threaded nut 23 being fixed.
  • a bushing 25 is also inserted into the part with the larger diameter of the bore 20, but this bushing can be rotated relative to the bearing housing 16.
  • the bush 25 in turn has an inner recess 26 in which a threaded nut 27 is mounted.
  • This threaded nut is connected in a rotationally fixed manner to the bushing 25 via a parallel key 28.
  • a gear 29 is connected in a rotationally fixed manner to the bushing 25 and is in drive connection with the pinion 31 of a motor 32 via a toothed belt 30.
  • This motor 32 is screwed to the gear housing 33, which is itself firmly connected to the bearing housing 16.
  • the threaded nut 27 is accordingly set in rotation, as a result of which the entire unit (16 and 33) can be moved back and forth together with the threaded nut 27 on the spindle 7.
  • the motor 11 is first of all switched on, what the spindle 7 rotates. Since the nut is rotatably mounted in the bushing 21 and this is firmly connected to the bearing housing 15, this moves away from the format cylinder 18.
  • the format cylinder 18 must still remain in the position shown in FIG. 2 for printing, for which purpose it is necessary that the motor 32 is also switched on, in such a way that the bushing 25 performs a counter-rotation, so that the bearing housing 16 is held on the impression cylinder 2 remains.
  • the motor 32 can be switched off, so that when the motor 11 is actuated further, the bearing housing 16 with the format cylinder also moves away from the central impression cylinder in addition to the bearing housing 15 becomes. Depending on the interaction of the motors 11 and 32, any position of the individual rollers with one another can thus be achieved.
  • the bushing 25 is held in the bearing block 16 by the bearing cover 34.
  • the two bearing housings 15, 16 can only be adjusted together by actuating the motor 11, without these making a relative movement to one another, but it is then expedient to keep the motor 32 braked.
  • FIG. 4 shows an embodiment which differs from that according to FIG. 2 first of all in that the spindle 7 'is held in the bearing blocks 5' and 6 'in a rotationally fixed manner.
  • the overall arrangement with regard to the bearing housing 16 ' is identical to the bearing housing 16.
  • the bearing housing 15' now does not correspond to the bearing housing 15 according to FIG. 2, but is of mirror-inverted design, white the bearing housing 16 '. If, at the end of printing, the screen roller 17 'is to be moved away from the format cylinder 18', the motor 32 '' switched on, which causes the sleeve 25 '' via the gear wheel 29 '' and, with this sleeve, the threaded nut 27 '' to rotate.
  • the entire unit formed from the bearing housing 15 'and the gear housing 33' moves away from the format cylinder 18 '.
  • the motor 32 ' can be switched on after a certain time, as a result of which the bushing 25' and the threaded nut 27 ', the bearing housing 16' and so that the format cylinder 18 'is also moved away from the central impression cylinder 2.
