Definitions

  • Such monitoring can be technically solved per se by known means, for example by monitoring each thread individually at each production site. For cost reasons, however, such solutions, at least on a larger scale, have never been implemented. The large number of production sites allows only a minimal cost per production site, so that the effort per machine remains within a reasonable range.
  • the invention relates to a device for monitoring rows of production sites on multi-spindle textile machines, with a moving sensor that is guided past the production sites and attached to a drivable carrier for the detection of the correct yarn path and / or a yarn break at the respective production site.
  • the aim of the invention is to improve the known device in such a way that the time between the occurrence of a thread break and its detection, the so-called detection time, is drastically reduced to a few seconds without the cost expenditure increasing significantly.
  • this object is achieved in that a plurality of hiking sensors are arranged on the carrier at an even distance from one another in that Division of the hiking sensors is a multiple of the division of the production points, and that the distance of the first and last hiking sensors from the first and last production point to be monitored is smaller than the division of the hiking sensors.
  • the acquisition time depends on the division, i. H. on the mutual distance of the hiking sensors, and this in turn is an optimization question of on the one hand the smallest possible division and thus short acquisition time and on the other hand as few sensors and thus low costs.
  • a division corresponding to the distance between 12 production sites would be very inexpensive compared to one sensor per production site, and it would also make sense to control a match stop, because compared to the known device with only one traveling sensor and, for example, 240 production sites, the acquisition time is reduced by over 95%.
  • the ring bank 1 of a ring spinning machine with n production sites P1 to Pn is shown schematically, where n can in practice be of the order of a few hundred.
  • a back and forth drivable carrier 2 is arranged along the ring bench 1, on which sensors S1 to SN for thread breakage detection are attached at the individual production points P1 to Pn.
  • the carrier 2 forms, together with the sensors S1 to SN, a so-called hiking sensor chain K.
  • the pitch T of the hiking sensor chain K i.e. the distance between two adjacent sensors S corresponds to the sixfold division t of the production sites P.
  • the first sensor S1 is located at the first production site P1
  • the second sensor S2 is located at the seventh production site P7, and so on
  • the last sensor SN is at the production site Pn-5. If the traveling sensor chain K is moved to the right by one production point (division t), then the first sensor S1 is located at the production point P2 and the last sensor SN at the production point Pn-4. After a total of five work cycles of the traveling sensor chain K - starting from the illustrated starting position - the first sensor S1 is located at the production site P6 and the last sensor SN at the last production site Pn. Then all production sites have been scanned once.
  • the hiking sensor chain K has reached its end position and can now be moved back to the left into the starting position shown (idle cycle). The cycle described is then repeated, etc.
  • the production points could also be scanned when the traveling sensor chain K moves backward. Then this backward movement would also have five work cycles.
  • the detection time of a thread break is a question of statistics. In the best case, namely when the thread break occurs exactly when the production site in question is currently being monitored by a sensor, it is zero. The worst case is when the sensor has left the relevant production site immediately before the thread break. because then the sensor can only detect the thread break after a total of five work cycles to the right and one idle cycle to the left.
  • the pitch T of the hiking sensors S can also be higher than 6 pitches t of the production sites P and can in practice be increased to 12 pitches t, for example, which considerably reduces the costs.
  • the acquisition time is still in a sufficient range for a match stop.
  • the electrical connections of the individual sensors S would have to be led out individually by the traveling sensor chain K. But it is also possible Lich to process the signals in each sensor S in such a way that they are sent in a suitable form to a bus system or, as in a shift register, are shifted in the traveling sensor chain K. Further examples could be added. However, since these are well known in electronics, they will not be described further here.
  • the rope length to be wound can also be stored in a small pulley 7 or 8 as shown.
