Definitions

  • the invention relates to a light barrier system for optoelectronic monitoring of fuses on flyers and is used in textile machine construction.
  • DD-PS 257 816 From DD-PS 257 816 an optoelectronic sliver monitor is known, which responds to the failure of a sliver by means of a light barrier. According to DD-PS 266 659, the presence of a fuse in a light barrier is evaluated. However, not all types of match breaks can be detected with these known solutions.
  • the invention has for its object a light barrier system to provide optoelectronic monitoring of a fuse on the flyer, which detects rupture breaks in the area from the drafting device up to and including the winding winding.
  • a vertical light barrier and a horizontal light barrier are arranged.
  • a breakage of a fuse 3 between the output roller (not shown) and winding results in the fuse 3 falling down and interrupting a light beam 4.
  • This light beam 4 is arranged so far below the fuse that a maximum sag a, which can occur in terms of textile technology, does not interrupt the light beam 4.
  • the vertical light barrier does not shut down the machine, since the fuse 3 does not release a light beam 5 when it falls.
  • Another technical arrangement of the vertical light barrier would not do justice to the textile technology sag of fuse 3.
  • An interruption in the fiber material in the drafting system area means that the fuse 3 does not appear after a certain time and the light beam 5 reaches the receiver 1 unhindered, as a result of which the machine is switched off.
  • the horizontal light barrier does not cause the machine to be switched off, since the distance a a caused by the textile technology means that the light beam 4 cannot be reached from the leaking fuse 3.
