Definitions

  • the invention relates to a device for checking the register-accurate clamping of printing plates on the plate cylinder of an offset printing machine by means of clamping rails arranged in the cylinder channel, on each of which a plate end can be clamped by clamping rails and which are supported by clamping screws which can be screwed into the clamping rails and are supported on each channel wall Cylinder circumferential direction are movable, the adjustment of the tensioning rail clamping the front plate edge relative to the plate cylinder being controllable by electrical display devices with a stylus extending in the direction of adjustment.
  • the invention is therefore based on the object of using an electrically indicating device to obtain an exact, plate-cylinder-related display of the position of the printing plate. This object is achieved with the characterizing features of the main claim.
  • the stylus tip of the stylus is in contact with a certain edge area of the printing plate front edge and there is a fixed relationship between this specific edge area and the positions of the printed images on the printing plate, since the mounting foils are stamped with the same register punch as the printing plates, the required registration accuracy is provided for multi-color printing .
  • the alignment of the pressure plate in the tensioning rails and the alignment of the mounting foils with respect to the pressure plates during plate production do not necessarily have to be carried out using the register punchings known per se, for example from US Pat. No. 3,835,778, but any other customary alignment system can also be used , provided there is a fixed relationship between the certain edge areas of the printing plate leading edge, at which the stylus tip of the '1' stylus is in contact, and the positions of the printing images on the printing plate.
  • register punchings are used on the printing plate, it is advantageous to produce the register punchings and at the same time further punching edges as certain edge areas for the contact of the probe tips in a common punching process on the printing plate leading edge.
  • the tensioning rail and the clamping strip can have recesses in the level of the clamped pressure plate front edge and at the location of the specific edge area engage the styli and touch the specific edge areas.
  • a stylus with associated position control device is arranged near the two ends of the cylinder channel.
  • the control devices are attached with a stylus to guide rails in the cylinder channel, on which the tensioning rails are also supported.
  • the position of the stylus With the help of mechanical pre-adjustment means with which the position of the stylus can be roughly adjusted, it is then pre-adjusted to the zero position and an exact one Fine adjustment can be made by electronic tuning if, as preferred, the longitudinal displacement of the stylus is detected by means of a capacitive length measuring device, as described in German Patent No. 28 30 432. This exact zero position is adjusted after the first prints with the device according to the invention.
  • the display device is designed as a measuring device indicating deviations on both sides of the zero position, that is, if the adjustment movement of the stylus relative to the zero position is not only ascertained but its size can be read. This can be easily achieved with the aid of the capacitive length measuring device according to DE-PS 28 30 432 mentioned above, an accurate digital display of the deviation being obtained.
  • the measuring device is battery-powered, so that no current leads to the device rotating rapidly with the plate cylinder are necessary.
  • the display of the adjustment path of the stylus relative to its zero position allows the printer to arbitrarily adjust the printing plate on the plate cylinder if it detects a registration difference of a printing ink in the proof. The exact zero position of the stylus can then be restored very easily for the next printing process.
  • FIG. 1 shows the front edge of a printing plate 1, in which, in a manner known per se, register punchings 2 are made with a register punch and, at the same time, punched edges 3 are attached in the same punching process, on which, as will be explained later, styli of the control device according to the invention are present.
  • printed images 4 are attached which are in a spatial relationship which is fixed by the assembly to the register punchings 2 and thus also to the punching edges 3.
  • the pressure plate 1 is shown in its clamping position in a clamping rail 5, in which register bolts 6, 7 are present, against which the plate with its register punchings 2 is pushed before the plate 1 is clamped in the clamping rail 5.
  • the tensioning rail there are laterally recesses 16 which are so deep that the punched edges 3 are exposed at the front edge of the plate, so that the tips of styli 18 can rest there and thus the position of the pressure plate 3 relative to a guide of the stylus can be determined.
  • FIG. 3 shows a section of a plate cylinder 10 in which 11 guide strips 14 for the tensioning rail 12 with their clamping strip 13 for the register system are fixed in a customary manner at the bottom of the cylinder channel.
  • the front edge of a pressure plate 1 is clamped in the same way as shown in FIG. 2, and the Perspective view of Figure 3 shows how the stylus 18 dips into the recess 16 of the clamping rail 12 and clamping rail 13 and is supported on the punched edge 3.
  • the tensioning rail can be displaced with tensioning screws 15, which are supported on the front wall of the cylinder channel 11, whereby the pressure plate 1 can be adjusted in its position relative to the guide strips 14.
  • the stylus 18 is guided in a measuring device 17, being within the measuring device 17 with, for example, the adjusting element one from DE-PS 28 30 432 known capacitive length measuring device can be connected, while the other elements of this length measuring device are fixed in the housing of the measuring device 17.
  • the entire measuring device 17 is also screwed onto the guide rails 14 with screws 21 when setting up the plate cylinder with the register system according to the invention.
  • the stylus 18 is able to determine changes in position of the punched edge 3 with the accuracy required for printing and to display them on a digital display 19 in relation to a zero position fixed when the machine is set up.
  • the measuring device permits a coarse mechanical adjustment for the set-up by means of a set screw designated 20, while after finding out the exact zero position of the stylus 18 the measuring counter 19 can be electronically fine-tuned, for example by resetting to zero.
  • FIG. 4 shows the entire pressure cylinder with the cylinder channel 11, in which the front tensioning rail with clamping rail 13 and a rear tensioning rail 22 are located, which are guided on the guide strips 14 and can be adjusted by clamping screws 15, 23.
  • the front edge of the pressure plate 1 is screwed into the front tensioning rail 13 and is pushed with its register punchings onto the register bolts 6, 7.
  • the side edges of the pressure plate 1 protrude laterally beyond the tensioning rails 13, 22, so that the punched-out areas with the punching edges 3 are exposed next to the tensioning rails and the styli of the two, arranged on both ends of the cylinder channel 11 and on one each Guide bar 14 screwed measuring devices 24 can freely attack the punched edges 3.
  • the main advantage of this construction is that there is a particularly large amount of space in the longitudinal direction of the capacitive length measuring device connected to the stylus 18.
  • the measuring device 24 can be supported on the Schmitz rings 25 of the plate cylinder.
  • FIGS. 3 and 4 clearly show that the stylus pins 18 of the measuring devices 17 and 24, which were screwed tightly during the setting up of the printing machine with the register system according to the invention and directly and coarsely adjusted to the zero position, directly the position of a printing plate 1 mounted on the plate cylinder with respect to the plate cylinder 10 itself is determined, regardless of any clamping errors of the front plate end with its register punchings 2 in the front clamping rail 5 or 12, 13.
