Definitions

  • the invention relates to a device for detecting the position of an edge of a processed material, which is fed to a printing press, with an opto-electrical measuring device designed as a reflex line, which consists of a lighting device and a receiver arranged at least two successive arranged CCD lines.
  • the reflex line consists of a lighting device and a receiver, which is composed of individual, one behind the other, formed as a functional units CCD lines.
  • the disadvantage is that in the areas between each two adjacent CCD lines imaging edge is not detected by the CCD lines. This means that such a reflex line is only limitedly suitable for detecting the format spectrum occurring within a format difference range. In addition, it is disadvantageous that, due to the length of the reflex line extending over the entire format difference range and consisting of series-connected CCD lines, long evaluation times result, which adversely affect the effectiveness of the device.
  • JP 2000241125 A describes a device for measuring flat objects, which is associated with a U-shaped frame.
  • the illumination device and in the other leg the photographic detection device is arranged, which consists of two spaced measuring lines.
  • the measurement lines are composed of spaced-apart elements, wherein the elements of one row are arranged in gap to the elements of the other row. Disadvantages are the high cost and the poor access to the processed material.
  • the object of the invention is to design a known reflex line such that it can detect edges of all formats occurring within a format difference range without restrictions and can be realized with little effort.
  • a feed table 1 with 2 processed, 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 extends transversely to the conveying direction 4.
  • the channel 7 extends at least over a format difference range 8 characteristic of the respective printing press.
  • the format difference range 8 is formed from the difference between the maximum and the minimum format of the sheets to be processed, so that the sheets 3 each have a format difference range 8 on both sides. However, it is described only on the basis of the direction of conveyance 4 on the left side format difference range 8, the device.
  • channel 7 designed as a reflex line 9 opto-electrical measuring device is arranged.
  • the reflective line 9 is permanently installed in the channel 7 and likewise extends at least beyond the format difference region 8. This ensures that the edge 6 of the processed material 2 to be supplied within the format difference region 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 reflective line 9 is in the embodiment of CCD lines 11, 12, 13, 14, 15, which are arranged with gaps one behind the other in a first row and in a second row. But it is also possible to provide another n CCD lines.
  • the first row and the second row are parallel to each other at a distance from each other, with the CCD rows 12, 14 of the second row and the CCD rows 11, 13, 15 of the first row are arranged in a gap to each other.
  • the opposite CCD lines overlap X.
  • Each of the CCD lines 11 to 15 is associated with an LED line 16 as a lighting device. But it is also possible to provide a trained as a functional unit, over the entire length of the reflective line 9 extending lighting device.
  • the CCD lines 11, 12, 13, 14, 15 consist of a plurality of measuring elements arranged side by side in a row.
  • the CCD rows 11 to 15 and their associated LED lines 16 are arranged at a distance from the processed material 2.
  • the rays emitted by the LED lines 16 are reflected in the area covered by the processing material 2 from the lower side of the processed material and detected by the measuring elements of the CCD lines 11 to 15, while in the area that is not covered by the processing material 2, no or Only a small reflection of the rays takes place, so that the position of the edge 6 as a light / dark difference on the CCD lines 11 to 15 images.
  • an actual signal is generated, which is supplied to a 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 supplied to the control elements for bringing the edge 6 of the processed material 2 into the desired position.
  • the CCD line 11-15 is determined during a circulation change by the processing electronics, on which the edge 6 is imaged.
  • the entire reflective line 9 is activated and a sheet 3 is transported to the feed table 1 and with the front edge against the front marks 5.
  • the edge 6 is formed on one of the CCD lines 11 - 15, which generates a signal which is detected by the processing electronics and thus determines the CCD line 11-15, which is required for the execution of the order.
  • the edge 6 is formed on the CCD line 11, so that only this, including the associated LED line 16 is driven by the processing electronics. It is of course taken into account that on both sides of the drawn in Figure 1 position of the edge 6, a tolerance range is taken into account, in which the sheets 3 arrive offset. If a format is processed in which the sheet 3 enters the edge 6, for example, in the region of the overlap X formed by the CCD lines 12, 14, the processing units electronics activate the CCD lines 12, 14 including the associated LED lines 16 and thus realized low evaluation times.
