Definitions

the present invention relates to a device for producing a spun Thread from a staple fiber association according to the preamble of claim 1.
Such devices are known in textile technology and are used for air spinning processes used. Such a device is disclosed, for example, by the document EP 854 214 (equivalent to US 5,927,062), which is shown in FIG. 1.
the fiber guide element 3.1 has a fiber feed channel 4 with a helical fiber guide surface 5 on.
the staple fiber bandage 1 is guided through the fiber guide surface 5, which ends at a fiber delivery edge 6.
At a certain distance from the Fiber guide element 3.1, or to the fiber delivery edge 6, is a spindle 7 with a yarn guide channel 8 and one associated with the yarn guide channel 8 Inlet mouth 9 provided.
FIG. 1 shows the air spinning device only schematically.
the Room 14 is normally enclosed by a housing and can therefore be used as a swirl chamber (14.1, see the following figures).
a fluid is usually compressed air is used. Due to the vortex flow 11 generated the free fiber ends 12 of the staple fiber assembly 1 around the inlet mouth 9.
a spun thread thus arises from the staple fiber structure 1 10th
the present invention is concerned with guiding the out of the fluid device flowing fluids (air). She is particularly concerned with the area of the swirl chamber 14.1 in the immediate vicinity of the outlet openings for the fluid.
FIG. 2 shows essentially the same components as in FIG shown in Figure 1 (with a change, see Figure 2a).
the outlet roller pair 2 and the spindle 7 with the yarn guide channel 8 can be seen.
Analogous to Figure 1 also generates a fluid device of a vortex flow here.
the jet nozzles consist of the Usually cylindrical bores from which a fluid (preferably air) under pressure in the vortex chamber 14.1 is pressed into it.
the vortex chamber 14.1 has a circular one Cross-section.
the fiber guide element 3.1 contains a sheathing 3a, which also forms the fiber feed channel 4.
a swirl chamber housing 15 In the device according to this Figure is the fluid device (represented by the bores or jet nozzles 13.1) integrated in the casing of the fiber guide element 3a.
the device is the swirl chamber housing 15 and the casing of the fiber guide element 3a two separate components. But it is quite possible and from the State of the art to construct both components as one element (in one piece). Whether these elements are constructed in one piece or as separate components irrelevant for the present application.
the fiber guide element 3.1 of FIG. 2 is in a three-dimensional View shown.
the fiber guide element 3.1 has FIG 2 not a helical, but a flat fiber guide surface 16.
Another The difference to Figure 1 is the lack of a fiber delivery edge. Instead of the fiber delivery edge the fiber guide element part 3b has a blunt cone. The The purpose of this cone 16 is to produce a so-called false yarn core.
the object of the present invention is to improve the flow conditions in the swirl chamber and thus the yarn values of the yarn produced.
the area of the vortex chamber should be in the immediate vicinity of the outlet openings of the Jet nozzles are improved in terms of flow.
the object of the invention is characterized by the features according to the invention Part of the main claim 1 solved. Further advantageous or preferred Embodiments of the invention are set out in the dependent claims.
the end face of the fiber guiding element adjoining the swirl chamber can can also be designed so that it serves as a guide surface for the vortex flow.
the end face can be designed in this way that it at least doesn’t disturb the vortex flow (because the Front surface has a greater inclination than the direction of flow of the emerging Fluid). In both cases, the adaptation of the end face also improves the inventive one Effect.
the fiber feed channel becomes the fiber guide between the outlet rollers and the entrance of the fiber feed channel (see Figure 1 or 2) improved.
the increased air flow the continuous bundle of loose staple fibers "sucks" through the fiber feed channel more intensely in the fiber feed channel.
the individual fibers in the staple fiber structure are better aligned by this flow, and the staple fiber dressing has less the tendency to "flutter” (from the Airflow around the rotating discharge rollers).
the number of production interruptions, caused by tears of the staple fiber association immediately after the Outlet rollers could be reduced by the configurations according to the invention. A measurable improvement in yarn quality was also found.
FIG. 3 shows a first embodiment of the invention.
the inventive The mode of operation will be explained somewhat using this figure.
the tunnel lining 17 can be in one piece or in several pieces, preferred to be in two pieces.
the fiber feed channel 4 is covered by the tunnel lining 17 jacketed.
the tunnel lining 17 is shaped such that at the end of the fiber feed channel 4 a paragraph 18 to the swirl chamber housing 15 is formed.
the face of the Paragraph 18 serves for the fluid emerging from the jet nozzles 13.1 (not shown) as a guiding surface.
the outlet openings of the jet nozzles for the fluid (usually air) have an elliptical shape in the swirl chamber 14.1 (see FIG.
FIG. 3 a shows the cross section 3 according to section I-I. In this Cross section can be seen that the device four individual jet nozzles 13.1 having.
the invention is not limited to only devices with four jet nozzles can be used. This means that it can also be used with devices with fewer or more than four jet nozzles.
FIG 3 is also clearly visible, like the jet nozzles 13.1, an inclination ⁇ to the direction of fiber transport (Material flow direction 19).
the angle of inclination ⁇ can amount to 45 ° to 88 °, but preferably the angle of inclination ⁇ is 70 ° to the material flow direction 19.
the angle of inclination of the end face of paragraph 18 to the material flow direction also has the same amount (shown in this first embodiment) are 70 °).
this first variant of the invention it is also easy to see how the end face 20 of the fiber guiding element 3 adjoining the swirl chamber 14.1 has the same angle of inclination to the material flow direction 19 as the holes in FIG Jet nozzles 13.1.
the angle of inclination of the holes corresponds to the direction of flow of the exiting fluid.
Figure 3 b shows a section of this first invention Variant according to section lines II-II.
the end face 20 of the fiber guide element 3 in alignment in the swivel bracket the end face of the shoulder 18. It can also be seen in FIG. 3a that the bores 13.1 are arranged rotationally symmetrically.
FIG. 3 c shows a top view of the fiber guide element 3.
the end face 20 of the fiber guiding element adjoining the swirl chamber 3 has a conical surface.
the conical end face 20 is cut off by a surface which forms the fiber delivery edge 6. From this It can be clearly seen from the figure that the end face 20 has a corresponding design can have a corresponding effect on the flow in the swirl chamber.
This figure also shows a half-shell of the tunnel lining 17.1 shown.
the tunnel lining can be in one piece or, as here shown, consist of two half-shells (upper half-shell not shown).
FIG. 4 shows an embodiment in which the end face 21 of the Fiber guide element 3 a larger i.e. steeper inclination to the material flow direction 19 has as the flow direction of the fluid (has inclination ⁇ ).
the area 21 has a larger (steeper) angle of inclination to the material flow direction 19 than the bores of the jet nozzles 13.1.
the surface 21 is flat and not conical. The steeper angle of the end face 21 causes this surface has a different effect on the vortex flow. Depending on the application this variant of the front face or another one may prove to be favorable Angle of inclination to choose.
the surface is the End face 21 of the fiber guide element 3 in the swirl chamber is also not conical. This is particularly evident from FIG. 4 a, which shows a section according to FIG Section line I-I of Figure 4 represents.
FIG. 5 shows a further embodiment of the invention.
the device in FIG. 5 differs from the preceding devices in the fiber guide element 22.
the end face 20 of the fiber guide element 22 in the swirl chamber has the same inclination as the jet nozzles 13.1 (inclination ⁇ ).
the end face of the shoulder 18 also has the same inclination, so that the surfaces 18 and 20 form an aligned, conical surface.
variants are also conceivable in which (in contrast to FIG. 4) the end face of the fiber guide element in the swirl chamber has a lower inclination than the shoulder 18 (not shown in the figures).
the fiber guide element 22 from FIG. 5 has a deflection point 23.
the deflection point 23 is designed as an edge; however, other types of deflection points can also be used Find application.
the remaining elements of the figure correspond to the previous one Description of why this is not discussed in more detail here.
the mode of action the deflection point 23 is explained in the following figure 6. Experiments have shown that in addition to using paragraph 18 as a baffle for the air as well the adaptation of the end face 20, especially with the use of a deflection point 23 good results regarding yarn quality can be achieved.
FIG. 6 tries to explain the mode of operation of the deflection point 23 somewhat. A More detailed explanation of the functioning of such deflection points can be at the time this application unpublished patent application by the applicant CH 0235/02 can be removed.
the fiber guiding element 22 with a deflection point guides one Staple fiber dressing 24 with the fibers arranged flat in the direction of the spindle 7.
the figure shows what the effect of the deflection point 23 is: at the deflection point 23, the free fiber ends 25 of the fibers in the staple fiber structure 24 can lift off (shown as an example). It can be seen that the free fiber ends 25 both front as well as rear fiber ends (corresponding to the left or right of the deflection point 23).
the staple fiber bandage 24 follows Pass the deflection point 23 more free fiber ends on or on the surface of the Has staple fiber dressing 24.
the deflection point thus increases the number of free fiber ends on or in the immediate vicinity of the surface of the staple fiber bandage. These free fiber ends can thus be better captured by the vortex flow 11 (or more free fiber ends are detected) and placed around the inlet mouth 9. This way, more free fiber ends can be spun, respectively more so-called wrapping fibers are produced, which affects the spinning process and the quality improves.
the spun thread 10 thus has a higher proportion of winding fibers and therefore higher strength than yarns from spinning devices without Deflection.
FIG. 7 has a tunnel lining 26, which is shaped such that at the end of the fiber conveying channel 4 Paragraph 29 with angle of inclination ⁇ arises.
the tunnel lining 26 preferably has one Thickness a which is in a range of 0.1 to 3 mm.
the thickness a is preferably Tunnel lining 0.5 mm.
the bore of the jet nozzle 13.1 arranged is.
the shoulder 29 is arranged so close to the opening of the jet nozzle 13.1, that the front side serves as a guide surface for the emerging flow.
the figure shows how the shoulder 29 is aligned with the bore.
the The bore is also aligned with the inner surface or lateral surface of the swirl chamber 14.1 arranged so that the bore 13.1 "tangentially aligned" in the inside of the Vortex chamber housing 15, or tangentially into the vortex chamber 14.1 enters. It cannot be seen in this figure that the jet nozzle 13.1 has an angle of inclination ⁇ can have to the material flow direction (see previous figures).
the inclination ⁇ of the jet nozzle to the material flow direction can range from 45 ° to 88 °, preferably in a range from 58 ° to 75 °, but inclinations are preferred used for the material flow direction of ⁇ equal to 60 ° or 70 ° (based on the Angle ⁇ of the previous figures).
the angle of inclination ⁇ of the front of the heel 29 may have a different amount than the angle of inclination ⁇ .
the most suitable The angle of inclination ⁇ can best be determined empirically for the specific application. Tests have shown that an angle of inclination ⁇ is suitable in most cases which has the same amount as the angle ⁇ . But the invention sees also use different angles.
the heel can be aligned with the holes recognizable from FIG. 7 b.
the tunnel lining 27 has a shoulder 30 an end face, which even has an inclination angle of 90 °.
the face of the paragraph can also be in alignment if the angle of inclination is not 90 ° is (see for example Figure 7).
the tunnel lining 28 has a paragraph 31 in FIG. 7 a, which (from the foot of the paragraph measured) has a distance d from the geometric center of the bore 13.1.
the inventive concept becomes apparent from a comparison of the paragraphs shown in FIGS. 7, 7 a and 7 b particularly recognizable: it is the idea, a paragraph or a surface to be provided in the middle or immediate vicinity of the outlet openings of the fluid device, which serves as a guiding surface for the exiting fluid (air). "Guiding" these guiding surfaces the emerging flow or vortex flow in a suitable manner, so that the vortex flow is optimally adapted to needs. It is essential that the paragraphs the tunnel linings or possibly also those facing the vortex chamber 14.1 or adjacent end faces of the fiber guide elements, the vortex flow manage cheaply. This is an essential functional feature of the invention. It is the most favorable form and arrangement of the paragraph for the respective application to choose.
the heel can therefore be aligned with a corresponding angle of inclination or arranged at a corresponding distance from the outlet opening of the bores 13.1 become.
Which is the cheapest option is empirical in the specific application (e.g. depending on the type of yarn or quality to be produced) determine.
the goal is in any case, the paragraph or the end face of the fiber guide element to be used as a guiding surface and thus optimal flow conditions or to achieve vortex flows for yarn formation.
the conscious use of this Surfaces as guiding surfaces for the vortex flow produce noticeable improvements of the spinning process.
devices are known from the prior art, which have vertebral chambers with shoulders (see for example Figure 2), it was previously not known to design such paragraphs as guiding surfaces. Such from the Previously known paragraphs were previously manufacturing technology in the vortex chambers contain or at least never had the function according to the invention.
FIG. 8 shows preferred arrangements of the jet nozzles.
the two Figures correspond to cross-section I-I from Figure 3, with correspondingly adapted Hole arrangement (compared to the arrangement of Figure 3).
the swirl chamber housing has a circular inner surface and the bore of each Jet nozzle "tangentially aligned" into the inner surface of the swirl chamber housing runs.
the inventive idea can also be applied to devices implement where the holes are not tangentially aligned in the cross section of the Vortex chamber housing run.
Figures 8 and 8 a therefore show only preferred Embodiments for implementing the invention.
FIG. 8 shows a variant, in which the longitudinal axis of the bore 33 of a jet nozzle parallel to the fiber guide surface 16 runs.
the tangential and aligned transition from the hole to the circular inner surface of the swirl chamber thus takes place in the zenith 34.
the fluid device in the swirl chamber housing a total of three or preferably four rotationally symmetrical arranged jet nozzles 13.1.
FIG. 8 a also shows four rotationally symmetrical jet nozzles.
the bores are arranged rotated about the longitudinal axis of the device (compare with FIG. 8).
the bore 33 of the one jet nozzle can also be arranged such that its longitudinal axis 35 pierces the lateral surface of the swirl chamber in the zenith 34.
the bore 33 of the one jet nozzle can also be arranged in a region between the latter two positions.
a plurality of jet nozzles are preferably used, which are arranged or distributed rotationally symmetrically around the longitudinal axis of the device (see FIGS. 8 or 8 a).
the invention and the inventive concept are not limited to those explicitly mentioned here Possibilities and embodiments limited.
the described and shown Variants are more than suggestions for the expert, the invention idea as far as possible cheap to use for each case.
the described embodiments are therefore easily advantageous arrangements and combinations derivable, which also reflect the inventive concept and through this application should be protected.
Some of the previously disclosed in the description and described features could also be claimed individually. It would be too conceivable, some of these features from the description in a different combination to claim as in the following claims.
the invention is particularly suitable in devices for air spinning, air preferably being used as the fluid becomes.
