Definitions

  • the present invention relates to a spinning device according to the preamble of claim 1.
  • Such a device is already known from Swiss Patent No. 529 231. 2, an outlet element is clamped by means of a screw and a delimitation element is screwed onto a front cover. Both of these parts together form an extraction channel for the thread running away from the spinning rotor. Both must be inserted and removed from the rear of the spinning device from the rear with respect to the operating side. The replacement of these parts is used in these devices primarily to adapt to different types of fibers, to replace a defective part, or to achieve desired yarn properties, such as their hairiness or twist.
  • a disadvantage of the known spinning device is that, on the one hand, in order to replace the outlet element or nozzle body, the latter has to be inserted into the spinning device from behind and removed to the rear. Accessibility is difficult due to the rearward replacement.
  • the parts of the known device which are screwed together also mean that tools such as screwdrivers, keys, etc. must be used for the replacement.
  • a serious disadvantage is therefore also that there is a risk of damage or scratching of the spinning device by the tools. This danger is further increased by the replacement from behind. Since these are systems of the highest precision, even small scratches can have adverse consequences.
  • the invention thus has the advantages of a tool-free operation when replacing the nozzle body, which eliminates the possibility of damage during such a replacement and replacement of the nozzle body from the front, which further simplifies this replacement process.
  • the extraction nozzle is held by a bayonet catch.
  • the trigger nozzle is inserted in such a way that its end part provided with lateral arms is carried out from behind through an opening in the housing cover which is congruent with the trigger nozzle and its arms and is then rotated.
  • the removal takes place through these two movements, which, however, take place in reverse order, that is to say in a very simple manner.
  • the replacement of the pulling nozzle thus represents a simple operation which can be carried out without any difficulty, despite being carried out from behind, and which can also be carried out without tools.
  • a spinning rotor 13 which is carried by a shaft 14.
  • the latter can be rotated in a rotary bearing 15.
  • the rotor housing 12 has a cover.
  • a sealing ring 17 is provided between the latter and the housing 12.
  • the nozzle which feeds the spinning rotor 13 fibers is not shown for the sake of clarity.
  • the cover 16 carries a discharge nozzle 18. This can be screwed onto the cover 16. In the example shown, however, it is attached to the lid in the manner of a bayonet lock. This attachment will be described in detail later.
  • the nozzle 18 has two arms 19 (see also FIG. 2). It also comprises a part of a take-off channel 20 for the thread 21 spun by means of the rotor 13.
  • a sliding seat 22 is attached to the cover 16.
  • a nozzle body 23 is carried by the latter. This is in its longitudinal direction, i.e. 1 in the direction of the axis 24, displaceable.
  • the nozzle body 23 is circular cylindrical in the embodiment shown.
  • a circular cylindrical bore is provided for the sliding set 22. This forms a precisely fitting seat for the nozzle body, but allows it to be moved in the axial direction.
  • the nozzle body 23 also comprises part of the draw-off channel 20 for the thread 21.
  • a hollow cylindrical ceramic piece 25 is attached at the outlet of the channel 20, a hollow cylindrical ceramic piece 25 is attached. This serves, inter alia, to influence the properties of the thread 21. Following the ceramic piece 25 is a pair of draw-off rollers 26.
  • the cover 16 together with the extraction nozzle 18 and the sliding seat 22 can be pivoted about a shaft 27 carried by the rotor housing 12.
  • the tube 37 serves to generate a negative pressure in the rotor housing 12.
  • this means consists of a leaf spring 28, which comprises an approximately U-shaped section 29, from which two legs 30 and 31 extend.
  • the leg 30 is attached to a fixed wall part 32 of the spinning device.
  • the extraction nozzle 18 has two arms 19. These are located at the point of contact of the extraction nozzle 18 and nozzle body 23 facing the end of the extraction nozzle 18.
  • the cover 16 on the other hand, has an opening with a circular cylindrical part 33 and with cutouts 34, which is congruent with the cross section of the nozzle 18 and the outline of the arms 19 .
  • the circular cylindrical part 33 corresponds to the cross section of the nozzle 18 and the cutouts 34 correspond to the Outlining the arms 19. The end of the nozzle 18 carrying the arms 19 can thus be moved through the opening 33, 34 from the left according to FIG. 1.
  • the nozzle 18 If the nozzle 18 is then rotated by 90 ° C., for example, and released, it rests on the cover 16 with its arms 19 as a result of the pressure of the spring 28, which acts on the discharge nozzle 18 via the nozzle body 23. As a result, the nozzle 18 is held in the manner of a bayonet lock, and because of the contact pressure exerted by the spring 28, the nozzle cannot be rotated.
  • the nozzle body 23 has a notch 35 in the contact area of the elastic means designed as a leaf spring 28, on the bottom surface of which the free end of the leg 31 of the spring 28 rests.
  • the width of the notch 35 is the same as the width of the leaf spring.
  • the spring 28 i.e. whose leg 31, in the direction against its bias, according to Fig. 1 to the right, e.g. pushed away by hand.
  • the body 23 can then be inserted into or removed from the sliding seat 22.
  • a coil spring can also be used. In this case, however, the simple rotational positioning of the part of the channel 20 formed by the nozzle body 23 does not result.
  • the sliding seat 22 can be provided with a trough-shaped embedding instead of with a round bore 36.
  • the sliding seat 22 and / or the nozzle body 23 e.g. be of angular cross-section.
  • a sliding seat with a cross-sectionally V-shaped trough or a nozzle body with a prismatic cross-section are present.
