Definitions

  • the invention relates to a referencing method for a machine or system for Processing of elongated, web and / or strand-like objects, particularly suitable for implementation in a printing machine for printing on paper webs.
  • the objects are drawn into the machine or system before they are processed, which for the object processing a plurality of movable functional components exhibit.
  • These are according to an internal machine or System coordinate system through drive units that can be synchronized with each other movable, and the drive units are controlled by sensors for actual values of the position, Relative position, speed and / or acceleration of the functional components and / or the drive units themselves according to internally generated setpoints and / or master setpoints from a superordinate master control computer-supported regulated.

It is proposed that the associated control devices with speed correction means for Change the relative phase angle of one or more drives provided are. The correction is to be carried out by means of a predetermined factor which is used for Overall speed of the printing press is proportional.
  • EP 0 664 214 A1 discloses a test run with two drive revolutions of Printing cylinders. This is intended to vary the circumferential register from Printing cylinder attached printing form sleeves can be determined. In a Subsequent correction run, the sleeves of the
  • Printing cylinders lifted off and the latter by the measured angular deviation twisted. Then the sleeves in the correct circumferential position on the Fix the pressure cylinder. Ultimately, that's one Referencing procedure between the printing cylinder and the clamping on it Printing form sleeves disclosed in a printing press, in which several printing units from a single, common drive via a common drive shaft ("Königswelle") are driven. None is specified, however, in one Printing machine with a large number of printing cylinders and individually assigned Drives the reference and synchronization between pressure cylinders and Manufacture individual drives when starting.
  • referencing is used to create a reference especially the position between the moving parts of a complex machine, for example, between the printing cylinders, folding units, etc., in addition to their Drive units of a printing press.
  • Referencing carried out during the installation and commissioning of the machine before the object to be processed, for example newsprint to be printed, in the (printing) machine is drawn in. Since the one to be carried out afterwards In any case, pulling in only at reduced machine operating speed can ring out, the task of the invention results in the requirement for a referencing method, by means of which during commissioning and when starting and starting a complex Machine for processing elongated, strand-like objects the necessary Time can be significantly reduced.
  • the synchronization is based on a Functional components and associated drive units common, virtual Leading axis performed, which is useful from one of the drive units Master controller master controller is specified.
  • an embodiment of the method according to the invention is advantageous after which the referencing is not in the higher-level control system, but as Function of the individual drive units implemented, i.e. over the entire Drive system is localized distributed. This makes referencing particularly easy flexible to specific boundary conditions of the respective functional or Adjust machine component.
  • part a the operating speed over time is the abscissa for example a ordinate applied to a printing press.

  • the machine is started to run up Operating, especially printing machine speed v2 for production too to reach.
  • the sum of the two time periods t2 and t3 gives that Synchronization period t4, at the end of which according to the invention
  • the individual drive units are synchronized with each other (cf. Phase c) above.
  • the basic position run according to phase b above is advisable in put the beginning of the second period t2 by installing and Commissioning of the machine is complete and this is normal operation is turned on, initially for retracting the objects, such as the to be printed on newsprint.

If this happens successfully within two revolutions, internal calculations and are carried out in the next calibration sequence step 392 Storage of the position of the encoder zero pulse by the digital Signal processor of the drive unit. This is followed by a in step 393 Acknowledgment of the order to the master control system, whereby the parameter "Order status" is set again. Then the parent transmits Master control with sequence step 394 the command "lock the drive unit".
