Definitions

  • the invention relates to a printing machine, in particular a web-fed printing press, according to the preamble of patent claim 1.
  • optical rotary encoders On printing presses for detecting the position of rotationally or rotationally driven components usually optical rotary encoder are used.
  • Such optical encoders have their own mechanical drive shaft and an independent storage, which has the disadvantage that the mechanical drive shaft of the rotary encoder must be mechanically connected by means of complex measures with a drive shaft of the component to be monitored with respect to their position.
  • This mechanical connection between the drive shaft of the rotationally driven or rotationally driven component and the drive shaft of the optical rotary encoder takes place at an axial end position of the drive shaft of the rotationally driven or rotationally driven component and thus at an axial position, which is usually exposed to high torsional stresses.
  • the quality of the storage version can be affected.
  • optical encoders are subject to wear, and that optical encoders are highly sensitive to contamination. Therefore, complex capsule measures are required in the prior art to protect the optical encoders from contamination. In any case, but consuming maintenance on optical encoders are required to clean them from time to time.
  • the present invention is based on the problem of creating a novel printing machine, in particular a novel web printing press.
  • the or each position detection device is designed as a magnetic rotary encoder.
  • rotatable components of a printing press as position detection devices magnetic rotary encoder.
  • non-bearing, magnetic absolute value encoders are used.
  • Such self-bearing, magnetic shaft encoder are exposed to virtually no mechanical wear and therefore have a virtually unlimited, mechanical life.
  • Magnetic encoders are insensitive to contamination.
  • the position detection is effected by the interaction of a dividing ring and a scanning head of the magnetic rotary encoder, wherein the dividing ring of the rotating component and the scanning head is associated with a fixed bearing element of the rotating component.
  • the position detection or position detection with such magnetic encoders is effected contactlessly via an air gap between the dividing ring and the scanning head of the magnetic rotary encoder.
  • the dividing ring may be disposed at almost any axial position of the drive shaft of the rotating component, preferably at an axial position which is subjected to a small amount of torsional stress. As a result, a highly accurate measurement is possible.
  • FIG. 1 and 2 show a section of a printing press according to the invention in the area of a printing machine cylinder 10 designed as a rotating or rotationally driven component.
  • the printing press cylinder 10 has a drive shaft 11 and is rotatably driven via the drive shaft 11 about a longitudinal central axis 12.
  • the drive shaft 11 is mounted on a fixed bearing element 13.
  • FIG. 2 shows a rotary bearing 14 for supporting the printing press cylinder 10 or the drive shaft 11 thereof on a stationary bearing element 13.
  • the printing press cylinder 10 is associated with at least one position detection device 15, wherein in the sense of the present invention, the or each position detection device 15 is designed as a magnetic encoder.
  • the printing press cylinder 10 is associated with two designed as a magnetic encoder position detection devices 15 so as to provide a redundant measurement option and to increase the reliability of the position detection on the printing press cylinder 10.
  • the or each magnetic rotary encoder is preferably designed as a self-storage, magnetic absolute value encoder.
  • Such self-bearing magnetic rotary encoders have a dividing ring 16 and a scanning head 17.
  • the dividing ring 16 is executed in the embodiment of FIGS. 1 and 2 as a separate assembly and fixed to the drive shaft 11 of the printing press cylinder 10.
  • the dividing ring 16 is connected via a clamping ring connection 18 to the drive shaft 11 of the printing press cylinder 10 or rotatably coupled, so that the dividing ring 16 together with the printing press cylinder 10 and the drive shaft 11 thereof rotates about the longitudinal central axis 12
  • the clamping ring connection 18 consists of two clamping ring elements 19 and 20, wherein a first clamping ring element 19 is seated on the drive shaft 11 and receives a second clamping ring element 20, wherein the second clamping ring element 20 presses the first clamping ring element 19 against the drive shaft 11 by tightening screws 21 and so on the drive shaft 11 rotatably fixed.
  • the dividing ring 16 is connected to the first clamping ring element 19 via screws 22.
  • the scanning 17 of preferably designed as a magnetic absolute value encoder position detection device 15 is associated with the fixed bearing element 13 and fixed to the stationary bearing element 13 fixed.
  • the scanning head 17 is arranged on a carrier element 23 and screwed on the support member 23 with a connection portion 24 of the fixed bearing member 13.
  • the scanning head 17 is screwed to the stationary bearing element 13 and the support member 23 such that a high rigidity is ensured in the circumferential direction or direction, so as to minimize vibrations of the scanning head 17 in the circumferential direction or direction of rotation of the printing press cylinder 10.
  • This is achieved in that an axially extending portion 25 of the support member 23, to which the scanning head 17 has screwed, in the axial direction has a relatively short extent. This results in the rigid connection in the circumferential direction of the scanning head 17 on the carrier element 23 of the fixed bearing element thirteenth
  • the dividing ring 16 of the magnetic rotary encoder 15 is connected to the output shaft 11 of the printing press cylinder 10 and rotates with the same.
  • the scanning head 17, however, is bolted to the fixed bearing element 13.
  • an air gap of the order of a few tenths of a millimeter is formed. The scanning and thus position detection or position detection takes place without contact via this gap.
  • the division ring 16 of the position detection device 15 embodied as a separate module in the exemplary embodiment of FIGS. 1 and 2 can be arranged via the tension ring connection 18 at almost any desired axial position of the drive shaft 11 or the component driven to rotate.
  • the dividing ring 16 is preferably non-rotatably connected at an axial position with the drive shaft 11, which is exposed to a low torsional stress. As a result, a high quality of the measurement result can be ensured.
  • the axial position of the scanning head 17 is determined by the fixed bearing element 13.
  • the axial position of the dividing ring 16 on the drive shaft 11 relative to the scanning head 17 is adjustable.
  • only the clamping ring element 19 with dissolved clamping ring connection 18 relative to the drive shaft 11 and relative to the stationary scanning head 17 must be moved to then fixed to adjustment by tightening the screws 21 in the respective axial position rotationally fixed on the drive shaft 11.
  • FIG. 3 shows an embodiment of the invention in which the axial position of the dividing ring 16 on the drive shaft 11 via a drive shaft 11 associated stop 26 is predetermined.
  • the scanning head 17 must be aligned relative to the dividing ring 16, wherein for this purpose the scanning head 17 is slidably guided via a guide member 27 in the support member 23 in the axial direction.
  • the dividing ring 16 has an inner diameter which is adapted to the outer diameter of the drive shaft 11 and the printing press cylinder 10.
  • the measurement signal provided by the position detection devices 15 can be used to realize a drive control for the printing press cylinder 10, to which the position detection device 15 is assigned. Alternatively or in combination with this, it is also possible for the measurement signal of the position detection device 15, which is assigned to the printing press cylinder 10, to be used for the drive control of another rotationally or rotationally driven component. In this case, the measurement signal of the position detection device 15 represents a control signal for another component of the printing press.
  • the position detection device is associated with a rotationally driven printing press cylinder. It should be noted that the invention can also be used on other rotationally driven components of a printing press, such. B. on a main drive shaft of a printing press, which is also referred to as a king shaft. In this case, the angular position of the main drive shaft is then monitored by means of a magnetic encoder, wherein based on the measurement signal provided a drive control for the main drive shaft and / or a drive shaft for other units of the printing presses, such. B. a folder, can be realized.
  • the dividing ring 16 of the magnetic rotary encoder is designed in each case as a separate assembly.
  • the dividing ring 16 is an integral part of the drive shaft 11, that therefore immediately the drive shaft 11 carries a corresponding magnetic division.
  • a self-storage and insensitive to contamination position measurement or angular position measurement is made possible on rotating components of a printing press.
  • Preferably used are non-bearing, magnetic absolute value encoders that detect the angular position of the rotating component at any time. Due to the almost unlimited, mechanical life of such position detection devices only a small amount of maintenance is required for the same.
