Definitions

  • the invention relates to a device for detecting the position of an edge of a material to be processed, which is fed to a printing press with a reflex line optoelectric measuring device consisting of an illumination device and at least one there are two consecutive receivers with CCD lines.
  • the object of the invention is to design a known reflex line so that it is without restrictions Edges of all formats occurring within a format difference range can capture.
  • the object is achieved by a device according to the features of the claim 1 solved.
  • the solution according to the invention makes it possible to minimize the evaluation times and a trouble-free detection of the position of an edge within a format difference area to realize.
  • a feed table 1 with processing goods 2, which is designed as a sheet 3, is shown.
  • the sheets 3 are transported in the conveying direction 4 on the feed table 1 and with the front edge against front marks 5.
  • a channel 7 is provided in the feed table 1, which runs transverse to the conveying direction 4.
  • the channel 7 extends over at least one format difference area 8 that is characteristic of the respective printing press.
  • the format difference area 8 is formed from the difference between the maximum and the minimum format of the sheets to be processed, so that the sheet 3 each has a format difference area 8.
  • the device is only described on the basis of the format difference area 8 located on the left in the conveying direction 4.
  • An optoelectric measuring device designed as a reflex line 9 is arranged in the channel 7.
  • the reflex line 9 is permanently installed in the channel 7 and also extends at least over the format difference area 8. This ensures that the edge 6 of the processing material 2 supplied within the format difference area 8 can be detected.
  • the channel 7 is closed with a transparent cover strip 10, so that the surface of the feed table 1 and the cover strip 10 form a common plane.
  • the reflex line 9 consists of CCD lines 11, 12, 13, 14, 15, which are arranged with gaps in a row in a first row and in a second row.
  • the first row and the second row run parallel to one another at a distance from one another, the CCD lines 12, 14 of the second row and the CCD lines 11, 13, 15 of the first row being arranged with a gap to one another.
  • the opposite CCD lines form overlaps X.
  • Each of the CCD lines 11 to 15 is assigned an LED line 16 as the lighting device.
  • the CCD lines 11, 12, 13, 14, 15 consist of a large number of measuring elements arranged side by side in a row.
  • the CCD lines 11 to 15 and the LED lines 16 assigned to them are arranged at a distance from the material to be processed 2.
  • the rays emitted by the LED lines 16 are reflected in the area covered by the processed item 2 from the underside of the processed item and detected by the measuring elements of the CCD lines 11 to 15, while none or in the area that is not covered by the processed item 2 there is only a slight reflection of the rays, so that the position of the edge 6 is shown as a light / dark difference on the CCD lines 11 to 15.
  • An actual signal is generated by the respective CCD line 11 to 15 and is fed to processing electronics.
  • the actual signal is compared with a target signal stored in the processing electronics and, in the event of a deviation, an actuating signal is generated which is fed to actuating elements for bringing the edge 6 of the material to be processed 2 into the target position.
  • the CCD line 11-15 on which the edge 6 is formed is determined by the processing electronics when the support is changed.
  • the entire reflex line 9 is activated and a sheet 3 is transported onto the feed table 1 and with the front edge against the front marks 5.
  • the edge 6 forms on one of the CCD lines 11-15, which generates a signal which is recorded by the processing electronics and thus defines the CCD line 11-15, which is required for the processing of the order.
  • the edge 6 on the CCD line 11 shows the edge 6 on the CCD line 11, so that only this, including the associated LED line 16, is controlled by the processing electronics. It is of course taken into account that on both sides of the position of the edge 6 shown in FIG. 1, a tolerance range is to be taken into account in which the arcs 3 run in offset. If a format is processed in which the sheet 3 runs in with the edge 6, for example in the area of the overlap X formed by the CCD lines 12, 14, the processing electronics activate the CCD lines 12, 14 including the associated LED lines 16 and thus realizes short evaluation times.
  • the CCD lines 11-15 colored light emitted from the LED rows 16 is used as a contrast-enhancing agent.
  • a contrast-enhancing means at a distance above the reflex line 9, which is designed as a colored or reflective layer applied to a carrier material.
