Definitions

  • the invention relates to a device for determining the register error between the individual colors in multi-color printing in a long-web web-fed rotary printing press, according to the preamble of claim 1.
  • any register error that may be present is first determined.
  • a generic device which is known, for example, from DE 40 37 728, there are two path probes in each scanning head, which can be designed, for example, in the form of fiber-optic sensors.
  • the path sensors can only be arranged at a minimum distance of 18 mm from one another due to their geometric dimensions. From this it follows again that the registration marks must be arranged at a minimum distance of 20 mm from one another.
  • the register error is determined by measuring the registration marks of the colors one and two, two and three and three and four. A time signal is determined as the measured value, which, multiplied by the respective web speed, results in the register deviation.
  • the device according to the invention only one path sensor has to be mechanically adjusted, it being possible in principle to carry out a scanning on the roller. Furthermore, web flutter can advantageously be prevented and the device according to the invention saves set-up time.
  • a level measurement is a measurement that the register deviation always relates to the first color.
  • the device according to the invention can be used, preferably automatically, to switch over to the previously described level measurement, which results in a reduction in waste.
  • the registration or printing marks are arranged one behind the other in the running direction of the printing sheet.
  • the print marks can be optically scanned, as in a conventional double web scanner, converted into an electrical analog signal and fed to the register controller.
  • advantageously only an electrical signal has to be fed to the register controller.
  • the path sensors are preferably designed as fiber-optic path sensors.
  • the registration marks in the device according to the invention are also seen in alignment in the running direction of the printed sheet, one behind the other and spaced apart from one another.
  • the mark spacing can be significantly reduced, so that the space problems explained at the beginning no longer occur when using the device according to the invention.
  • an electronic window is set by the evaluation device to select the registration marks to be scanned and evaluated. This selects the marks to be scanned, so that the register marks which must be used to determine the respective register error are always scanned and evaluated at each measuring point, despite the aligned arrangement of the registration marks and despite the presence of only a single path sensor.
  • FIG. 1 shows a schematically, greatly simplified representation of a register control device for monitoring a long-web web-fed rotary printing press, which comprises a determination device according to the invention
  • FIG. 2 shows a greatly simplified schematic illustration of a section of a printed sheet with registration marks and schematically indicated web buttons
  • FIG. 3 shows a representation corresponding to FIG. 2 of the arrangement of the registration marks with the assignment of a schematically greatly simplified path scanner; 4 shows an exemplary representation of a graph of signals which are generated by means of the device according to the invention;
  • FIG. 6 shows a representation corresponding to FIG. 5 of a second example for signal generation.
  • a register control device with a controller 1 for monitoring a long-web web-fed rotary printing press 2, as is known in principle from DE 40 37 728 C1, and in the present case the invention according to the invention according device is integrated. Since the present invention is embodied both in a separate device for determining the register error and in a regulating device which comprises this device according to the application as claimed, the complete disclosure content of DE 40 37 is added to the disclosure content of this application 728 made by reference to the content of the present application.
  • the long web web-fed rotary printing press 2 shown in FIG. 1 has four printing units 3 to 6 in the example, in which the colors yellow, red, blue and black are successively applied to a material 7 to be printed in the form of a running printing sheet.
  • each of the printing units 3 to 6 each has a printing cylinder 8, 9, 10 and 11 rotating in an ink bath.
  • the material web 7 is passed through the printing units 3 to 6 one after the other, in each case being guided over the printing cylinders 8 to 11.
  • Each printing unit of the long-web web-fed rotary printing press 2 also has a drying device 12, 13, 14 and 15, which, viewed in the direction of travel of the material web 7, is arranged subsequently to the associated printing cylinder 8, 9, 10 and 11, respectively.
  • the drying devices 12 to 15 can be designed, for example, in the form of a drying drum.
  • the printing units 3, 4 and 5 are provided with a register roller arrangement with actuators 16, 17 and 18, each of which has a correction motor 19, 20 and 21 respectively.
  • the register control device which represents a control device arranged in a housing (not shown), has a central unit 22 for recording and storing all control parameters and the control behavior.
  • the register control device preferably has control units designed as plug-in modules, of which the control unit 23 is shown in FIG. 1. These control units serve to control the longitudinal register and / or to combine the longitudinal and lateral register, and for this purpose act on the previously mentioned correction motors 19 to 21 of the respective actuators 16, 17 and 18.
  • the device according to the invention for determining the register error between the individual colors in the multi-color printing carried out in the long-web web-fed rotary printing press 2 is integrated in the overall arrangement illustrated in FIG. 1.
  • the device according to the invention has a scanning device 24, which comprises each measuring point in the printing units 4, 5 or 6 scanning heads 25, 26 and 27, and which contains the register or registration marks P1 to P4 (see FIG. 2 , 3) capture.
  • the scanning heads 25, 26 and 27 are arranged at a suitable point in the printing units 4, 5 and 6 in the running direction L of the web material 7 behind the printing cylinder.
  • the scanning heads 25, 26 and 27 are connected to a signal recording unit of the scanning device 24, which in turn forwards the determined signals to an evaluation device 33 which is connected to the central unit 22 and which determines the relative positions of the individual registration marks P1 to P4 with respect to one another makes.
  • the device according to the invention has only one single path sensor per scanning head 25 to 27, which is identified in FIG. 1 by the reference symbols T 1 or T 2 and T 3 .
  • the web scanners T- to T 3 are preferably designed as fiber-optic web scanners which optically scan the registration marks P1 to P4 and generate electrical analog signals which are fed to the evaluation device 33.
  • the evaluation device 33 uses the supplied signals to determine the relative positions of the registration marks P1 to P4 and the results are fed to the control unit 23 via the central unit 22, which in turn is connected to the correction motors 19 via lines 40, 41 and 42 , 20 and 21 is connected to perform the register correction.
  • FIG. 2 shows a section of the material web or the printing sheet 7 with four print images 43, 44, 45 and 46 in the example.
  • the registration marks P 1 to P 4 are assigned to the print images 43 to 46 a side strip 47 of the printed sheet 7 are also printed when printing the printed images 43 to 46.
  • Fig. 2 illustrates the assignment of Path scanner T- ⁇ to T 3 to the print images 44, 45 and 46. There is therefore only a single path sensor T lf T 2 and T 3 is provided per measuring point and scanning head, which scans the respective registration marks and generates the corresponding signals.
  • Fig. 3 shows the arrangement of the registration marks Pl and P2 and their distance A to each other.

  • the resulting counted number of pulses corresponds directly to the distance, or the distance A between the register marks (e.g. 5 pulses corresponds to 5 mm distance A), so that an immediate distance measurement can be carried out with the device according to the invention. If the determined distances deviate from the previously known actual distances between the registration marks, the respective register deviation can be determined.
  • FIGS. 5 and 6 For further explanation and disclosure of the device according to the invention, reference is made explicitly to FIGS. 5 and 6 below.
