Definitions

  • the present invention relates to a method for controlling a printing press with a plurality of printing units and a plurality of mechanically coupled to each other cylinders and a control computer for controlling at least one drive motor which drives the mechanically coupled cylinder.
  • Sheet-fed rotary printing presses in offset printing have several printing units which each apply an extract of a printed image in a specific color to the printing substrate. Usually there are at least four printing units to print the three basic colors red, yellow, blue and black. For special colors, such as gold or silver, however, other printing units can be provided. In addition, it is possible to apply a coating to the substrate using a special coating unit following the printing units. Sheet-fed rotary printing presses can also process the front and back of a substrate, so that in this case a double number of printing units and coating units is provided. This leads in printing machines for perfecting with several special colors and subsequent coating units now a stately number of printing and coating units; In the meantime, a number of 16 printing and coating plants are no longer unusual in packaging printing.
  • the individual printing and coating in sheet-fed rotary printing presses are usually connected to each other via a gear train.
  • the plate cylinder, blanket cylinder, impression cylinder and transport cylinder and turning drums of the printing press mechanically coupled together and are driven together by one or more drive motors.
  • the mechanically coupled cylinders represent a system with finite rigidity, so that set at certain loads torsional phenomena.
  • the present invention is applicable to all printing machines in which a plurality of printing cylinder, blanket cylinder, plate cylinder or transport cylinder are mechanically coupled together.
  • the mechanical coupling causes changes to one of the cylinders inevitably affect the other cylinder coupled with this.
  • the invention is therefore almost predestined to be used in sheet-fed offset printing presses, in which all cylinders or at least a majority of the cylinders are connected to each other by a mechanical coupling, such as a continuous gear train or a longitudinal shaft.
  • the printing machine also has at least one drive motor which drives the mechanically coupled cylinders and a control computer in which a mathematical torsion model in the form of software for describing the torsional state of the rotatably mechanically coupled cylinders is stored in the control computer of the printing press.
  • This torsion model represents an algorithm which can continuously recalculate the mechanical rotation and position of the individual cylinders coupled to one another as a function of at least one measurable operating parameter or a variable known to the control computer even during operation of the printing press.
  • the operating parameters and the known variables may be, for example, the current torque of the one or multiple drives, the recorded power of the drives, operating temperatures, used printing units, switched-on components, settings of the ink fountain openings in the printing units, etc. act.
  • the control computer can then intervene in the control of the printing press.
  • This procedure has the great advantage that it is also possible to take into account changes in the torsional state of the printing press during the printing operation which arise, for example, due to the change of environmental conditions such as temperature and humidity.
  • the printing machine can be smoother or heavier during operation, so that this can also result in changes in the torsional state of the coupled cylinders. If the corresponding operating parameters of the printing press are detected by sensors and fed to the machine computer with the torsion model, corresponding values can be calculated to correct settings of the printing press and the corresponding setting processes are triggered.
  • At least one characteristic variable for the power requirement of the at least one drive motor is measured as the operating parameter and supplied to the control computer of the printing press.
  • the power requirement of the printing machine can be detected, for example, by measuring the absorbed current of the drive motor. The larger the detected current, the more electrical power the drive motor draws from the power grid.
  • the power requirement of the drive motor can change, for example, by changing the printing speed. When the printing speed is increased, the power requirement of the drive motor inevitably changes, because a higher printing speed requires correspondingly more drive power. But even with constant printing speed, the power requirement of the printing machine can change, for example, by heating. However, changing the power requirements of the press does not affect the settings.
  • the torsional model in the machine computer can be used to determine the effects on the torsional state of the machine Printing machine to be calculated. Corresponding changes to the settings of the printing press can then be initiated by the control computer.
  • measured as the operating parameter by the at least one drive motor fed into the cylinder torque and the control computer of the printing press is supplied.
  • the torque fed into the cylinders of the printing press can also be detected.
  • the torque detection can also be done via the drive motor or via additional torque sensors, which measure the torque on individual cylinders of the printing press or on gears of the gear train.
  • the detected torque values are likewise supplied to the torsion model in the machine computer of the printing press, so that the torsional state of the printing press can be calculated there as a function of the respective detected torque. Even so, the corresponding, necessary settings on the printing machine can then be made by the control computer.
  • the registration is particularly sensitive when overprinting the different color separations to achieve high print quality, which relates to changes in the operating condition of the printing press. This applies above all to changes in the torsional state of the interconnected cylinders in the printing press.
  • the gear train can relax when heated and during the processing of a print job, which has a change in the register setting result.
  • the printer learns of such a register setting only by pulling test sheets and noticing the change in the registers there, or has installed an automatic register monitoring in the printing press, which automatically adjusts the register deviation.
  • Such automated register monitoring is expensive and not available for every press.
  • appropriate special Measuring marks to be provided on the substrate, which claim corresponding space on the substrate, which could otherwise be used for the printed image itself.
  • the printer so desires, the changed values of the register adjustment can first be displayed on a screen of the printing press, so that the printer can decide for himself whether he wants to make the register adjustment by hand or leaves it to the press. In the latter case, the printer can thereby be facilitated the work that the register adjustment is done automatically by the control computer of the printing press. In this case, the printer does not have to worry about adopting the correct register-registration values.
  • This adjustment ensures that the paper edge in the transport gripper on a reference cylinder, preferably in the middle of the machine or near the main drive, is tracked to a reference state when changing the operating state. This increases the reproducibility of the sheet transfer by the homogenization of the paper projection on the reference cylinder, wherein the paper projection in the front printing units, however, is also changed.
  • the adjustment of the front mark is possible.
  • the printing press has a measuring device for monitoring the registers and that in the detection of register deviations in the control computer by means of Torsionsmodells a correction of register adjustment and / or the adjustment of the front mark in the printing units.
  • control of the registers is provided in addition to the control by register marks on the substrates in the printing press or on a separate measuring table are detected and this the control computer of the printing press be supplied.
  • the detected deviations in the registers of the individual printing units or coating units are also supplied to the torsion model in the control computer of the printing press, so that in the calculation of the manipulated variables for the correction of the register deviation in the control computer torsion in the press can be taken into account.
  • the register adjustment and / or the adjustment of the front mark is set correctly for at least one selected operating state of the printing press and the correct setting values of the register adjustment and / or the adjustment of the front mark in connection with the associated selected operating state stored in the control computer of the printing press become.
  • the selected operating state may be, for example, a specific machine configuration or a specific printing speed.
  • the printer in a set-up operation which is carried out at a low printing speed, the printer can itself set the registers in the individual printing units until the result corresponds to his wishes.
  • the selected print speed in this case is the setup speed. In this way influences from the printing plate exposure, the clamping operation of the printing plates and the torsional state of the machine can be corrected at set-up speed.
  • the printer can then acknowledge this with respect to the control computer of the printing press by a corresponding input.
  • This acknowledgment signal triggers a memory operation, at the set register adjustment values, the currently recorded drive power or the torque as well as additional other data in the printing press control be stored. Thereafter, the printer can then switch the press to print mode and bring to full machine speed.
  • the machine control uses the torsion model and the stored register adjustment values at set-up speed to calculate corresponding register adjustment values in order to ensure perfect pressure even at full machine speed. This eliminates the otherwise usual for the printer manual tracking of register adjustment values when the printing speed of the printing press changes.
  • an operating parameter acts on a plurality of components or printing units of the printing press.
  • an operating parameter may be the power consumption or the torque requirement of the printing press.
  • the torsion model takes into account and describes the torsional state and thus the coupling of the cylinders in the individual printing units of the printing press, the effect of the adjustment of registers in the individual printing units is taken into account.
  • the torsion model can be used to calculate the effect of an operating variable, such as the power requirement, on all printing units or coating units of the printing press, so that the Machine control on the register adjustment then make the appropriate corrections to all printing or coating units.
  • the torsion state of the printing machine is detected by means of sensors at least two locations.
  • sensors are to be provided in at least two places, which are e.g. additionally measure the torsion via the applied torque or the differential rotation between the sensors.
  • the measured values can be taken over into the torsion model so that it can be checked for correction at least two times.
  • the measured values can be used to interpolate intermediate values through the torsional model.
  • the measured values determined by means of the sensors can also be used to optimize the torsion model during operation. In this case, the measured values are taken into account in a type of learning control by the parameters of the torsion model are adjusted continuously or at certain intervals accordingly.
  • the distribution of torque in the printing units of the printing press is variably adjustable or takes place as a function of the machine configuration.
  • register corrections can also be carried out by changing the torque distribution in the individual printing units, for example as a function of the printing speed. This can be done by braking in the printing units, or it can be provided additional drive motors with which the torque distribution can be changed. It proves to be particularly advantageous if the torque distribution of the drive motor in the printing units takes place as a function of the respective configuration of the printing units.
  • the torque requirement in the individual printing units depends, among other things, on how many printing units are actually used for the respective print job, whether, for example, in straight printing or in reverse printing and how each ink fountain opening is. All these configurations, which depend on the print job, have one changed torque requirement in the individual printing units result. Also, this need can be calculated by means of the torsion model, so as to improve the print quality on the substrates.
  • the changing torsional state of the printing press is calculated, that the register deviation is calculated from the calculated torsional state, which has undergone a printing material in the printing press before the turning drum, and that the register adjustment for the printing units the reversing drum with twice the value of paper edge loss relative to the printing units before the turn to correct the register deviation are applied.
  • the deviation of the register between the front and back of the substrate is corrected via the register adjustment at the printing units and coating after the turning device.
  • the register value is calculated by means of the torsion model.
  • all the register setting values are corrected by twice the detected paper edge loss, so that no registration deviations occur between the print images on the front side and the back side. It is therefore also possible by means of the present invention to reliably avoid register deviations in perfecting.
  • a further advantageous embodiment of the invention results from an improvement of the model results by means of a machine-specific calibration test. Since both the flexibility of the gear train and the current / torque characteristics of the drive can have smaller variations, the individual result on a machine can be improved by performing a standardized pressure test under real conditions before delivery of the machine to the customer and the statements of the torsion model then improved with the help of the values found therefrom such as be scaled. In the simplest case, a scaling factor over all values is superimposed for correction. This calibration is required only once.
