Definitions

  • the present invention relates to a yarn forming element for an air-jet spinning machine, which is used to produce a yarn from a fiber structure with the aid of a vortex air flow, the yarn forming element having a spinning tip with an inlet opening, in the area of which a yarn can be produced with the aid of the vortex air flow, the yarn forming element having a having the main body connected to the spinning tip, and wherein the yarn forming element has a take-off channel for a yarn produced in the area of the spinning tip, which extends through the spinning tip and the base body and opens into an outlet via which the yarn produced in the area of the spinning tip is extracted from the yarn forming element can escape.
  • a spinning nozzle for an air-jet spinning machine which is used to produce a yarn from a fiber structure with the aid of a vortex air flow, the spinneret having a vortex chamber partially surrounded by a vortex chamber wall with an inlet opening for a fiber structure and a yarn forming element extending at least partially into the vortex chamber
  • the swirl chamber being assigned air nozzles which are oriented in the direction of an outer surface of the yarn forming element and via which air can be introduced into the swirl chamber in order to give the fiber structure a rotation in the region of an inlet opening of the yarn forming element, and wherein the yarn forming element has a discharge duct adjoining the inlet opening through which the yarn can be drawn off from the swirl chamber.
  • a yarn-forming element correspondingly consisting of a base body and a spinning tip connected to it is, for example, from FIG 10 2011 053 837 A1 , of the DE 103 33 411 A1 or the EP 3 012 362 A2 known.
  • the spinneret described herein contains a yarn forming element opening into a swirl chamber with a take-off channel for the yarn produced in the swirl chamber, the typical air-spinning rotation of the fibers of the fiber composite to be spun around a non-twisted fiber core in the area of the inlet opening of the spinning tip.
  • Another embodiment with a multi-part yarn guide element is for example in EP 2 573 219 A2 shown.
  • the object of the present invention is therefore to propose a yarn-forming element and a spinneret equipped therewith for an air-jet spinning machine which take this requirement into account.
  • the yarn forming element is now characterized in that the spinning tip and the base body are connected to one another with the aid of at least one snap connection.
  • the base body can be designed in one or more parts. The same applies to the spinning tip.
  • the main body and the spinning tip are separate units of the yarn-forming element, which are connected to one another with the aid of one or more snap connections.
  • a snap connection within the meaning of the invention is a connection which comprises one or more functional elements for the releasable, form-fitting connection of the spinning tip and the base body.
  • the functional elements can be, for example, elastic hook or clip elements which, when connected, engage in a corresponding functional element in the form of a recess or undercut.
  • a spring can also be used as a functional element, which acts on a ball or other element with a force in a defined direction.
  • one or more of the existing functional elements of the snap connection can be part of the base body. At least one functional element is formed by a sleeve according to the invention, which is described in more detail below.
  • connection there is a form fit between at least two functional elements of the snap connection, which can be released again by pulling apart the spinning tip and the base body.
  • the spinning tip which is exposed to increased mechanical stress during the spinning operation due to the fibers passing on its surface can be easily replaced by a new spinning tip.
  • the snap connection should be designed in such a way that the spinning tip and the base body can be separated from one another manually and without the use of a tool.
  • the snap connection should also be designed in such a way that the separation takes place in that the spinning tip and base body are pulled apart in a direction running colinearly to a longitudinal axis of the draw-off channel.
  • the connection is preferably made in that said sections of the yarn-forming element are moved towards one another in the direction mentioned until the snap connection engages.
  • the snap connection can be produced without the use of a tool and can then be released again without damaging the components of the yarn-forming element.
  • the snap connection comprises a functional element in the form of a snap ring.
  • a snap ring is a retaining ring with an interruption in the circumferential direction.
  • the basic shape of a snap ring is in Figure 3 (Reference number 22).
  • the interruption in the circumferential direction makes it possible to deform the snap ring by a force exerted radially on the snap ring to such an extent that the ends present due to the interruption touch one another. This reduces the diameter. If, for example, the base body now has a recess (e.g.
  • the snap ring in the form of an annular groove in which the snap ring is located in the area of an outer surface, it is compressed in the radial direction when the sleeve, which is explained in more detail below, extends over the area of the The main body is pushed, which has the snap ring.
  • the snap ring can again assume its original shape, provided, of course, the sleeve has an internal recess in the area of an internal surface into which the snap ring can snap or engage.
  • the spinning tip is held on the base body with the aid of a sleeve, the snap connection holding the sleeve and thus the spinning tip on the base body.
  • the sleeve is part of the snap connection and preferably has a, in particular ring-shaped, recess in the area of an inner surface, into which the snap ring engages when the sleeve is pushed over the spinning tip and finally over part of the base body.
  • the sleeve preferably has a first circular opening through which a section of the base body protrudes and a second circular opening through which the spinning tip protrudes.
  • the first opening preferably has a larger diameter than the second opening.
  • the sleeve should have an annular shoulder in the region of the second opening (ie the inside diameter of the sleeve should increase starting from the second opening in the direction of the first opening). If the spinning point also has a corresponding annular shoulder, the sleeve can indeed be pushed over the spinning point. In this case, however, the spinning tip has an outer diameter in the area of its annular shoulder which is greater than the inner diameter of the second opening. The In this case, the sleeve is suitable for holding the spinning tip on the base body, since the spinning tip cannot pass completely through the sleeve.
  • the spinning tip preferably rests against the base body directly or with the interposition of an annular seal when the sleeve is pushed completely onto the base body.
  • the sleeve and / or the spinning tip should be designed to be rotationally symmetrical. If the sleeve is pushed over the spinning tip and finally over a section of the base body during assembly, the spinning tip and the sleeve do not have to be aligned at a certain angle of rotation relative to the base body and the sleeve relative to the spinning point in the circumferential direction of the above-mentioned openings of the sleeve. This simplifies the assembly of the yarn-forming element.
  • the above-mentioned functional elements of the snap connection are also preferably formed by a snap ring, which is arranged in an annular groove of the base body and by a recess on the inside of the sleeve (which is preferably also implemented by an annular groove), the snap ring when the Yarn-forming element snaps into the recess of the sleeve.
  • a tensile force that is at least 30 N, preferably at least 50 N, must be exerted on the spinning tip or the sleeve, parallel to the discharge duct and in the direction of the inlet opening.
  • the snap connection is sufficiently secure to prevent the spinning tip or the sleeve from becoming detached from the base body during operation of an air-jet spinning machine equipped with the yarn-forming element.
  • the sleeve has an opening facing away from the spinning point, the opening being circular and the radially extending wall thickness of the sleeve increasing at least a little in a direction of the sleeve that is colinear to the exhaust duct starting from the opening.
  • the wall of the sleeve is preferably conical in the area of the opening mentioned (already referred to above as “first opening”).
  • the base body also has the snap ring described above, the sliding of the sleeve over the snap ring and its compression in the radial direction is also simplified.
  • the sleeve has a recess, preferably in the form of an annular groove, which is arranged in the area of an inner wall of the sleeve and into which the snap ring extends.
  • the sleeve engages in the desired end position on the base body when it is pushed onto the base body.
  • the snap ring is therefore preferably surrounded on the outside by an annular groove in the sleeve and on the inside (i.e. in the direction of the exhaust duct) by an annular groove on the base body. Both ring grooves thus form an annular channel in which the snap ring is located.
  • the base body is made of metal
  • the spinning tip is made at least in sections of ceramic
  • the sleeve is made of plastic.
  • the sleeve can be manufactured particularly inexpensively, the base body and the spinning tip being the have the necessary rigidity or, in the case of ceramics, the necessary wear resistance.
  • sealing rings are arranged between the spinning tip and the base body.
  • the sealing ring or rings (which can consist of rubber, plastic or metal) should surround the exhaust duct, preferably concentrically.
  • the sealing ring (s) preferably also run concentrically with the aforementioned snap ring (if present). In any case, the sealing ring (s) prevents air flowing through the take-off channel during the spinning operation from escaping laterally between the spinning tip and the base body.
  • a spinning nozzle which, in addition to a vortex chamber known from the prior art and the air nozzles responsible for the vortex air flow during the spinning operation, comprises a yarn forming element protruding into the vortex chamber.
  • the yarn-forming element is designed according to the previous or following description.
  • Figure 1 shows a partially sectioned view of a spinneret 13 for an air-jet spinning machine.
  • the spinneret 13 has an inlet opening 16, which can be formed, for example, by a separate fiber guide element 20 and through which the fiber material to be spun and usually present as a stretched sliver enters the so-called vortex chamber 15 of the spinning station, in which the actual spinning process takes place.
  • the stretching is usually carried out by a (not shown) upstream of the fiber guide element 20 of the corresponding spinning unit of the air-jet spinning machine (which usually comprises a large number of spinning units, which in turn each have a spinneret 13 and a drafting unit), from which the drawn fiber sliver is also With the help of a pair of take-off rollers, also not shown (alternatively, the take-off can also be done by other means, e.g. a yarn storage roll).
  • the fiber material After the fiber material has passed the fiber guiding element 20, it reaches the active area of several air nozzles 18, which usually open tangentially into the vortex chamber 15 and which can be present, for example, as bores within a vortex chamber wall 14. If this is done during the spinning operation via a corresponding If an overpressure is applied to the supply line (not shown) opening into an air duct 21, for example, a vortex air flow arises which flows around the area of a yarn forming element 1 protruding into the vortex chamber 15 or its outer surface 17 (at least some of the air introduced finally leaves the vortex chamber 15 again via a corresponding air outlet 19).
  • multi-part yarn-forming elements 1 which consist of a base body 6 and a spinning point 4 connected to it. In these cases, however, the connection is always made with the aid of screw connections or a press fit that cannot be released.
  • the present invention now proposes realizing the base body 6 and spinning tip 4 with the aid of at least one snap connection.
  • the base body 6 can have a recess, preferably an annular groove 12, which is used to receive a snap ring 22.
  • a sleeve 10 is provided, which likewise has a recess (preferably in the form of an annular groove 12) in the area of its inner wall 11. If the sleeve 10 is now fitted with the in Figure 3 The opening 9, which can be seen, is pushed over the spinning tip 4 and then over the base body 6, so the snap ring 22 engages in the annular groove 12 of the sleeve 10 in the intended end position of the sleeve 10. The snap connection is thus established, the spinning tip 4 and the base body 6 are connected.
  • the opening 9 mentioned can be designed conically so that the wall thickness D of the sleeve 10 increases gradually starting from the opening 9.
  • a sealing ring 23 is preferably present between the spinning tip 4 and the base body 6, which prevents air from escaping from the side between the base body 6 and the spinning tip 4.
