Definitions

  • the invention relates to a weft distributing device of a row shed loom with air intake. Such a device is described in EP-PS 0 143 860.
  • the interfaces for the weft thread are located relatively far from the fabric wheel and discontinuous movements of transmission elements are necessary for the distribution of the weft threads.
  • Another advantageous embodiment is the subject of the present invention. It solves the task of distributing and blowing into the different weft channels of a weaving rotor with low acceleration forces in the weft thread.
  • the object is achieved in that the device has a stationary part and a part rotating with the weaving rotor, which have a common rotationally symmetrical separating and sealing surface, via which the transfer of weft threads takes place, and by a shooting tube on the rotating part of each weft channel Part is assigned, in which a feed nozzle, which is positioned in the stationary part, blows the weft by means of air.
  • a weft distributing device of a row shed loom with air intake is shown.
  • the warp threads 9 from the warp beam 1 are guided tangentially to a rotating weaving rotor 4 via deflections 3 and deflected within a certain deflection area by combs 6, which are arranged in rows to form weft channels 7, for shed formation.
  • weft threads 10 are inserted, which are taken along with the combs dipping through the warp threads until the newly formed cloth runs tangentially.
  • the cloth is wound on the merchandise tree 2.
  • the weft threads 10 are distributed by a thread feed device 31 to a plurality of weft channels 7 of a weaving rotor 4 in that the device has a stationary part 21 and a part 11 which also rotates with the weaving rotor 4 and which have a common separating and sealing surface 20 in a rotationally symmetrical surface.
  • each weft channel 7 is assigned a shooting tube 12 on the rotating part 11, into which a feed nozzle 22, which is positioned in the stationary part 21, blows the weft thread 10 by means of air.
  • the orifices 15 of the shooting tubes 12 lie on a shooting circle 8 and are evenly distributed there for each feed nozzle 22 and offset from one feed nozzle to the next at a weft channel distance.
  • the transition of the weft thread from the stationary to the rotating part takes place from a connecting channel 24 in the stationary part 21, which describes a circular arc piece in the direction of rotation and is open to the separating and sealing surface 20, to a take-over channel 14, which in the rotating part 11 with the stripping shoulder 13 of the shooting tube 12 begins, which continues in the direction of rotation as a circular arc piece with the same diameter as the connecting channel and which is open to the separating and sealing surface, so that over time from the departure of an opening edge 16 on a fixed edge 27 until the arrival of the Ab Scraper shoulder 13 on the edge 27 no blind spaces must be passed when entering a newly formed weft tip.
  • the scraper shoulder 13 goes away from the separating and sealing surface 20 at approximately a right angle. From Fig. 3 it follows that the preceding stripping shoulder 13a and its associated shooting tube 12 are open for a certain time at the same time as the following shooting tube 12 to the connecting channel 24 so that the new weft thread tip created in the clamping and cutting device 32 is pulled back and can be entered via the following shooting tube 12.
  • the coaxially arranged feed nozzle 22 and auxiliary nozzle 26 blow against the direction of rotation at an acute angle to the center line of the connecting channel 24 and act as an injector to counteract this seen in the direction of rotation, on the one hand generates an overpressure in the area behind the nozzle opening via a mixing section and on the other hand generates a negative pressure in relation to the atmosphere in the area in front of the nozzle opening.
  • an auxiliary nozzle with a square outlet cross section which coaxially includes a feed nozzle with a circular cross section, has proven to be advantageous.
  • the thread feed device 31 delivers the weft thread 10 to the weft circle at a higher speed than the peripheral speed, a thread loop is created in the connecting channel to the new shooting tube 12, as long as the weft thread is clamped and cut at the outlet of the associated shooting tube 12. After the new weft thread tip has been cut and released, the loop continues into an elongated weft thread within the weft distribution device.
  • 7 relay nozzles 33 are attached along the weft channels, which support the weft insertion from the shooting tubes 12. Clamping and cutting devices 32 are positioned between the bullet tube 12 and the weft channel 7 formed from combs 6.
  • the cutting can be carried out with a stationary tool into which the weft threads 10 inevitably run with the rotational movement of the mouth 15 and the weft channel 7.
  • the inserted weft thread 10 must be in predetermined circumferential positions with respect to the stationary part 21, e.g. to the feed and auxiliary nozzles 22, 26, clamped, cut and released as a new weft tip.
  • the size and the time course of the pulse of the air flow from the feed nozzle 22 and / or auxiliary nozzle 26 are also controlled as a function of the circulating position of the associated weft thread 10.
  • the air flow in the guide channels 24, 14, 12 and the air flow of the relay nozzles create a tensile stress in the weft thread, which causes it to bear against the inner diameters of the circular arc pieces from the connecting channel 24 and from the take-over channel.
  • the weft thread 10 shifts more to the channel base and away from the separating and sealing surface 20.
  • the weft distributing devices shown here can be used to shoot weft threads 10 into a weaving rotor 4 from both sides, with correspondingly more weft channels 7 forming compartments, both systems having to be offset by a weft channel division and the relay nozzles of both systems being oriented in opposite directions have to.
