Definitions

  • the invention relates to a honing roller device for monitoring the run of two superimposed paper webs in a paper processing machine, with photoelectric Sensors whose light rays hit the surface the paper webs are directed.
  • the account postprocessing system has one so-called slitter / merger unit. In this unit a wide paper web is initially cut by slitting knives divided longitudinally in the middle so that two webs half as wide are created. These two Paper webs are then placed on top of each other and transported exactly on top of each other. Because the wide paper web already has cross perforations is provided, which is arranged at a distance from the format height , it can happen that one of the paper webs tears and not together with the second paper web is transported further. That is why it is a control device required the presence of two superimposed paper webs monitored. An acquaintance Control device works with a light barrier, which illuminates both paper webs simultaneously. The light barrier must be set so that when there are two sheets of paper there is no light strikes the receiver photocell while missing the light beam the remaining paper web penetrates and hits the receiver photocell.
  • the light barrier must from the operator of the machine to the respective transparency of the paper webs are adjusted. If this is forgotten the control device then reacts during processing a paper quality with less transparency at all no longer or no longer reliable. For thicker ones Papers or those with little transparency is the known control device not suitable at all.
  • From US-A-4 467 949 is a paper conveyor known for a printer in which the paper web promoted by a motor-driven drive roller becomes. Behind the drive roller is for monitoring the Paper web a light emitting diode and opposite this optically aligned phototransistor is provided. If there is no paper web between the diode and the phototransistor the latter is switched on, if there is a paper web between the two, then this interrupts the light coming from the diode and the photo transistor is turned off.
  • This facility is only for monitoring a single paper web, but not for monitoring two superimposed ones Paper webs suitable, because the light beam is already interrupted by a single paper web, even if the second paper web is no longer available is.
  • the invention is therefore based on the object Control device for monitoring the run of two superimposed paper webs in a paper processing machine of the kind mentioned at the beginning, which is reliable monitoring with a simple structure of paper webs of any transparency without that adjustment work when changing the paper quality required are.
  • the invention is therefore based on the idea of running each individual paper web by its own, on Reflection responsive photoelectric sensor too monitor. If the run is trouble-free, that of each sensor emitted light beam from the associated Paper web reflected and from the receiver part received the same. However, if the assigned Then tear paper web in an area in front of the plate becomes the surface facing the torn paper web the plate is no longer covered by the paper web, as soon as the end of the cracked end adjacent to the crack Paper web has passed the plate. Because the surface the plate has a different reflection behavior than the paper web, the torn paper web reacts assigned sensor and gives a corresponding signal from. The surface of the plate can be selected that it guarantees a different reflection behavior than all types of paper that the paper processing Machine should go through.
  • 1 and 2 are two superimposed Paper webs referred to in a paper processing Machine lying one on top of the other in paper feed direction A. become.
  • the control device 3 has a thin plate 4 on, which extends in the paper running direction A and the engages at the edge of the paper webs 1, 2 between them.
  • On the two opposite sides of the plate 4 is each a photoelectric sensor 5 responsive to reflection or 6 arranged.
  • the light rays 5a and 6a of these two Sensors 5, 6 are perpendicular from opposite sides on the assigned paper web 1 or 2 and the plate 4 located behind it directed.
  • the surfaces 4.1 and 4.2 facing the sensors 5, 6 plate 4 must be opposite paper webs 1 and 2 have completely different reflectivities. After paper, especially white paper, which is here mostly to be processed, good reflectivity has, the two surfaces 4.1 and 4.2 designed to absorb light.
  • the surfaces 4.1 and 4.2 can be blackened.
  • the entire can also be expedient Plate 4 consist of black plastic.
  • the sensors 5, 6 are set or designed so that they Impact of reflected light does not respond. However, tears e.g. the upper paper web 1 in the running direction A in front of the plate 4, then the surface 4.1 is not more covered by paper web 1 once that to the Crack adjacent end of the plate has passed. Of the Light beam 5a is from the black surface 4.1 then no longer reflected. This is from the receiver part of the sensor 5 recognized and a corresponding Signal the machine is stopped.
