Description
The present invention relates to a kind of fiber guide element, it is used to manufacture sir jet spinning machines used in yarn from fibre bundle
Spinning jet nozzle, the fiber guide element have matrix, and outer surface is used for the cooperation table of the spinning jet nozzle against spinning position
Face, so as to allow for fiber guide element to be fixed on spinning jet nozzle be introduced into opening region in, and the fiber guide member
Part has inner surface, can be in contact during the operation of spinning jet nozzle with fibre bundle, and for guiding fibre bundle.
Sir jet spinning machines with respective fiber induction element and be public in the prior art equipped with its spinning position
(such as the seeing 40 36 119 C2 of DE) known, and for manufacturing yarn by elongate fibers.The outer fiber of fibre bundle by means of
The vortical flow generated by the indoor air nozzle in whirlpool is fine around inner core in the aforementioned region for being introduced into mouth that yarn forms element
Dimension winding, and ultimately form winding fiber vital for the required intensity of yarn.This, which is generated, has the true twist
Yarn is finally discharged from volute chamber via extraction channel, and can be wound up on such as reel.
In general, term " yarn " is for the present invention for indicating that at least part fiber surrounds the fibre of inner core winding
Tie up beam.Therefore, equally include yarn on conventional meaning, such as fabric can be processed by means of loom.However, this hair
It is bright to further relate to sir jet spinning machines, so-called rove (also referred to as thick fine) can be manufactured by means of it.The feature of such yarn
It is, although it has the intensity for the certain level for being enough for yarn to be delivered to subsequent frame, it is still can drawing-off.Rove
Therefore can it by before clearly spinning by means of drafting system such as drawing frame or by means of handle rove frame such as ring
Ingot spinning machine obtains drawing-off.
However, independently of the intensity of yarn, it is still desirable to be the twist that generates in the region that yarn forms element not
Introducing opening can be propagated through outward in contrast to the direction of the supply of yarn or fibre bundle.In other words, it is necessary to ensure that the fiber of fibre bundle
Their original orientation is kept before contacting with vortical flow, and the corresponding twist is only obtained in volute chamber.That is,
If the twist is propagated in contrast to the direction of the supply, the associated back rotation of fibre bundle will inevitably lead to fibre bundle
Drawability in the region of the drafting system of volute chamber upstream.
Although above-mentioned document propose be directed toward yarn formed element direction pin to prevent above-mentioned propagation, it is same known
Be the introducing opening that volute chamber is realized by the opening of so-called fiber guide element, which forms element relative to yarn and draws
Enter mouth and is provided with laterally offset.This offset for causing fibre bundle that must pass through before actually manufacturing yarn prevents fibre bundle
The twist is propagated by the friction between fibre bundle and fiber guide element in contrast to the direction of the supply.
Even if can be reduced the non-required inverse of the fiber twist generated in the region that yarn forms element through the above scheme
The danger that row is propagated, however, there remains keep punching further to improve the required effect of fiber guide element.
Therefore the object of the present invention is to provide the spinners of a kind of fiber guide element and associated sir jet spinning machines
Position, further improves fiber guide in the region between present delivery roller pair and volute chamber in fact.
The purpose is achieved by the fiber guide element and spinning position of the feature with independent claims.
According to the present invention, fiber guide element has inner surface, in fiber guide element perpendicular to fiber guide member
It include multiple preferably radially inwardly directed protuberances in the section that the central axis of part extends, at least part protuberance at least exists
There is the profile being inwardly tapered in proparea towards central axis.In other words, (it is in fiber with inner surface for fiber guide element
Be in contact under the installation condition of induction element with fibre bundle and guide it), profile be different from roller tube, and have cause
The increased elevated regions of surface area and recess.Therefore there are inhomogeneities in inner surface, send out in inner surface and fibre bundle
When raw contact, lead to the fiber end of at least close fiber and fibre bundle being outwardly oriented with guidance.Fibre bundle is in prior art public affairs
It is not subjected to any radial directed in the slippery inner surface known, and fibre bundle connects when it passes through fiber guide element with protuberance
Touching, so that twisted in the region of fiber guide element of fibre bundle can be prevented almost.Because protuberance (or at least
Their overwhelming majority) in their propareas towards central axis (that is, extending in farthest region towards central axis)
With the profile being inwardly tapered, so the blocking of fiber or its excessive loads are almost excluded, (term " introversion " is herein referred to
The gap by swelling circular fiber guide element passed through for fiber).
Preferably, the inner surface has at least partly tortuous in aforementioned section and/or is at least partly in
Wavy profile.It is easily understood that fiber guide element of the invention also has when observing in cross section and to be circumferentially closed
Inner surface, therefore it is straight line herein that term " complications ", which should not be misinterpreted as referred to part,.On the contrary, meander-like or wavy
Internal cavities of the part for example with ring style around fiber guide element extend, and then pass through for fiber or fibre bundle.It is interior
Surface can only be formed by meander-like or wavelike segmentss.However, it is also contemplated that be that corresponding portion replaces or inner surface

Extend.Furthermore it is advantageous that all protuberances are radially extended along the direction of the central axis of fiber guide element is having the same
(alternatively, the degree of radially extending of each protuberance can also be different in size, and in the fiber guide formed by fiber guide element
Increase and reduce several times in the circumferential direction in channel).
It is moreover advantageous that protuberance tapers to a bit along the direction of the central axis of fiber guide element.This causes inwardly
The edge of orientation ensures to the particularly reliable radial directed of the fibre bundle of process.Tapering to these parts of any can be
It is sharp or rounding, it in the later case almost can (fiber type, stack length, fiber be straight independently of its physical characteristic
Diameter etc.), exclude the damage to fibre bundle.
Particularly advantageously the central axis that protuberance is parallel to fiber guide element extends.In other words, protuberance is in the situation
Under upwardly extended in the regulation supplying party of fibre bundle so that its guidance almost only carries out in radial directions.In contrast, fiber
Almost it is not subjected to the close negative shadow relevant to friction for matching and guiding, therefore not having to concern fiber conveying in the Shu Qi direction of the supply
It rings.Alternatively, protuberance in this case can also may be used with spiral-shaped extension (central axis relative to fiber guide element)
To be wound in the region that yarn forms element along the regulation direction of rotation of fibre bundle or in opposite direction.
Advantageously, inner surface includes the trough and wave crest configured in the aforementioned section of fiber guide element, aforementioned section

Fig. 2 shows the perspective view of fiber guide element of the invention,
Fig. 3 shows the front view of fiber guide element shown in Fig. 2,
Fig. 4 shows the longitudinal section of fiber guide element of the invention,
Figures 5 and 6 show the side view of the other fiber guide elements of of the invention two,
Fig. 7-12 shows the front view of fiber guide element of the invention, and
Figure 13-16 shows the different embodiments in (part) section of spinning position of the invention.
Fig. 1 shows the schematic diagram in the section of the spinning position 32 of sir jet spinning machines (it is easily understood that sir jet spinning machines
There can be multiple spinning positions 32, be preferably arranged to adjacent to each other).As needed, sir jet spinning machines may include drawing frame 27,
It is supplied to fibre bundle 4, such as in the form of drafting drawing-off sliver.In addition, shown spinning position 32 includes spinning jet nozzle 2,
Its with internal volute chamber 18, wherein at least part fiber of fibre bundle 4 or fibre bundle 4 be provided with the twist (spinning position 32
Definite working method will be described in greater detail below).
In addition, sir jet spinning machines may include a pair of involving roller 31 and configuration and involving 31 downstream of roller the pair of
Winding mechanism 29 (is equally schematically shown), has the reel 30 for winding the yarn 3 for leaving spinning position 32.This hair
Bright spinning position 32 not necessarily has drawing frame 27 as shown in Figure 1.It is the pair of to involve roller 31 nor absolutely
It wants.
Shown spinning position 32 works generally in accordance with air-jet spinning method.In order to form yarn 3,4 quilt of fibre bundle
Guidance via be provided with is introduced into opening 8 fiber guide element 1 enter spinning position 32 volute chamber 18 in (this point also can be found in scheme
13-16).The twist is given for it herein, that is, at least part of the free-fiber end 28 of fibre bundle 4 is by air nozzle 19
Air-flow generated introduces, and the air nozzle 19 is properly configured in the spiral wall 20 of volute chamber 18.A part of fiber
It is at least drawn from fibre bundle 4 to a certain extent, and forms the tip winding of element 21 around the yarn charged into volute chamber 18.
Since fibre bundle 4 forms drawing in element 21 via yarn is arranged in by the introducing mouth 22 that yarn forms element 21 from volute chamber 18
Channel 23 is drawn out, and free-fiber end 28 (see Fig. 1) is last equally to be drawn along the direction for introducing mouth 22, and by itself around residence
The core part fiber (so-called winding fiber) of middle configuration is wound, so that yarn 3 be caused to have the required twist.
As general remark, it should be clarified that manufactured yarn 3 can be any fiber composite material in principle here
Material, which is characterized in that the exterior section of fiber (so-called winding fiber) around fiber interior section (it is preferably non-twist or
It is similarly twirl as needed), to assign required intensity for yarn 3.Therefore the invention also includes such a jets
Spinning machine can manufacture so-called rove by means of it.Rove is such a yarn 3, the winding with relatively low ratio
Fiber or such a yarn 3, wherein winding fiber is relatively loosely wound around inner core, so that yarn 3 is kept
For can drawing-off.This be it is vital, if manufactured yarn 3 will or must be in subsequent frame (for example, RING SPINNING
Yarn machine) on be drafted by means of drawing frame 27 to allow appropriate be further processed.
About air nozzle 19, for the sake of only careful, it is also noted herein that be that it should generally be oriented such that institute
The air-flow of generation is rectified into the parallel airflow for having direction of rotation convenient for mutually manufacture.Preferably, each air nozzle configuration
At rotational symmetry relative to each other, and tangentially import in volute chamber 18 (note that air nozzle 19 is not shown in figs. 13-16, with
Just it becomes apparent from).
Preferably, also there is the twist in insertion such as fiber guide element 1 from spinning position 32 known in the art
Holding element.It is pin that this is implementable, is partly wound by such as fiber, and prevent fibre bundle 4 along inversely in the confession of fibre bundle 4
Propagate to the twisted direction to the introducing opening 8 along fiber guide element 1 direction T (this by yarn formation process have it is negative
Face is rung, because corresponding be twisted together will be released again after the introducing mouth 22 for forming element 21 by yarn, part
Ground releasing is applied twisted).
However, because edge 36 shown in Fig. 1 or comparable configuration element placed in the middle can be always only from internal action in around twirls
The fibre bundle 4 for spending holding element, so the effect is limited by it.In addition, mechanical load occurs for fiber, in twist holding element
Region in be subjected to the lateral deflection that can not ignore.
In contrast, spinning position 32 of the invention now have novel fiber guide element 1, the twist in contrast to
Antidromic propagation is offset in the case where the direction of the supply T of fibre bundle 4, and winds the quantity of fiber needed for not excessively reducing or causes
The non-required mechanical load of fibre bundle 4.
As finding out when can watch Fig. 2-12 together, the figures illustrate fiber guide elements 1 of the invention
Multiple embodiments, fiber guide element 1 are characterized in that inner surface 9 is in fiber guide element 1 perpendicular to central axis 11 now
It include several preferably radially inwardly directed protuberances 10 in the section of extension, at least part protuberance 10 is at least towards center
There is the profile being inwardly tapered in the proparea 33 of axis 11.
The inner surface 9 of fiber guide element 1 can for example have meander-like profile (example in the section of fiber guide element 1
Such as, see Fig. 2 and 3).Inner surface 9 is formed by multiple protuberances 10, and then limits a succession of alternate trough 12 and wave crest 13.
Specifically, it is advantageous especially with regard to this point advantageously, fiber guide element 1 defines trough 12 and wave
The central axis 11 that the wall portion 14 at peak 13 is at least partly parallel to fiber guide element 1 extends, for example, as shown in Figure 2.Wall portion
14 additionally advantageously define angle [alpha], between 10 ° to 70 °, preferably between 20 ° to 60 °, particularly preferably at 30 ° to 50 °
Between.In this regard, as can be seen from Figure 7, the angle in the region of wave crest 13 can be advantageously located at about this point
Spend the angle (being α 2 in Fig. 7) that (being α 1 in Fig. 7) is different from the region of trough 12.It is easily understood that α 1 and α 2
But it is identical.
When its fiber guide channel 24 for being formed simultaneously spinning position 32 of the fibre bundle 4 of fiber guide element 1 is (see Figure 13-
16, it illustrates fiber guide elements 1 to be in possible installation condition, wherein its outer surface 6 with it is close match or press-fit against
The corresponding matching surface 7 of spinning jet nozzle 2) when, outer fiber component is in contact with aforementioned wave crest 13.This forms one kind and just connects
It connects, finally preventing the twist of fiber generated in volute chamber 18 from propagating in contrast to direction of the supply T is more than fiber guide element 1.
In addition, as shown in the figure, trough 12 and wave crest 13 can be configured by distribution mode in the fiber guide channel 24 preferably configured between two parties
Periphery on so that the size of corresponding wave crest 13 and trough 12 respectively corresponds to each other.Alternatively, certainly it is also feasible that will
The wave crest 13 and trough 12 of fiber guide element 1 are arranged so that its size is variation (for example, seeing Fig. 9).
Similarly, the corresponding turning point 25 of inner surface 9 can be (such as seeing Fig. 3) of horn shape, or can also be (the example of rounding
Such as see Fig. 7 or 11).
It is additionally noted that the matrix 5 of fiber guide element 1 (it is preferably implemented as single component, as shown in the figure)
Not necessarily for example there is as shown in Figure 3 on section rounded outer profile.On the contrary, on section be oval (Fig. 8) or
The design of polygon is also to be contemplated that.Similarly, this winding end for being equally applicable to wave crest 13 or trough 12.Here, together
Sample, circular shape (such as seeing Fig. 3) and different shape such as oval (see Fig. 9) are also to be contemplated that.
Other possible cross sectional shapes are also shown in Figure 10-12.It can be seen, for example, can think such as from above-mentioned each figure
To be that trough 12 is partly formed with holes (see Figure 10 and 11).Similarly, trough 12 and/or wave crest 13 can for flat condition or
Concavely or convexly (Figure 12) of rounding.
Finally, it is conceivable that the configuration of fiber guide element 1 in the region of front side 34 (in Fig. 1 be located at left and right) extremely
A few wall 16 extends into inward slant, to obtain the gap 15 of conical butt.If only correspondingly implementing a front side
34, then fiber guide element 1 can be oriented such that the side of volute chamber 18 is directed toward in the front side 34 (see Figure 13-16) in the mounted state
To.However, same it is conceivable that fiber guide element 1 is installed in spinning jet nozzle 2 with inverted orientation, so that by fiber guide
The gap 15 that element 1 is formed is used as a kind of funnel for fibre bundle 4.In addition, by wall 16 and fiber guide around gap 15
The angle beta that the central axis 11 of element 1 is formed also should be between 30 ° to 60 °, preferably between 40 ° to 50 °, particularly preferably
(it is also possible that the wall slightly convex or concavity as needed, they are by position in this case between 42 ° to 48 °
In on the surface of such as virtual sphere).
Alternatively, fiber guide element 1 can also have the section arched upward outward at least in the region of one of front side 34,
Such as show in figs. 5 and 6, lead to the outer diameter D 3 of fiber guide element 1, preferably along the provided supply of yarn 3
Direction T is tapered.Its section can be along the basic configuration with such as truncated cone, and the lateral surface 35 that is outwardly oriented can be shown respectively
Exterior contour with convex (Fig. 5), concavity (Fig. 6) or linear (not shown) in side view.
Finally, as from Figure 13, (it for example shows fiber guide element shown in Fig. 21 and is in installed in spinning jet nozzle 2
In state) with the comparison of Figure 14-16 it can be seen, final advantageous can be additionally is equipped with one for fiber guide element 1
A or multiple guide portions 17 (such as being four in Figure 15 and 16) spaced apart, supply of the mutual spacing along fibre bundle 4
Direction T reduces (at least in cross section).In other words, spinning position 32 has several elements, acts on fibre bundle 4 from outside,
And it is closer to each other along the direction of the supply T of fibre bundle 4.Therefore fibre bundle 4 is inevitably in contact with guide portion 17, and one
Determine to be taken away by them from outside in meaning, so that its being twisted together in the region of guide portion 17 is further prevented.
However, despite the presence of the fiber guide acted on from outside, in order to ensure the local detachment of outside fiber end 28 is
Feasible, a kind of measure that can also carry out is that guide structure is made to further include at least one center induction element 26 (see Figure 16),
Extend between such as guide portion 17 in the section of the central axis extension perpendicular to fiber guide element 1.Although outside is drawn
Portion 17 and protuberance 10 " from outside " guidance fibre bundle 4 are led, and center induction element 26 is to be located at fibre during the manufacture of yarn
4 "inner" of beam is tieed up, therefore it is caused to press off.In other words, fiber is deflected outward by center induction element 26, or with geometric terminology and
Speech, perpendicular to the central axis 11 of fiber guide element 1.As a result, free-fiber end 28 is also gradually pressed outward, by
This makes the area for also ensuring that fiber reaches the air-flow generated by air nozzle 19 despite the presence of guided outside portion 17 and protuberance 10
Domain, and can be wound around fiber core.
Although (it is equal preferably about the central axis 11 and/or center induction element 26 of fiber guide element 1 for guide portion 17
Evenly and equidistantly configure) and center induction element 26 can be placed in except yarn formation element 21, it is however also conceivable that
Be guide portion 17 or center induction element 26 extends to yarn and forms (not shown) in the extraction channel 23 of element 21.
In addition, center induction element 26 is not necessarily equipped with water-drop-shaped as shown in figure 16 or spherical front.On the contrary, it
Also it may be embodied as guidance mandrel, be tapered to a bit (quite with shown guide portion 17).Guide portion 17 nor is it necessary that presence,
Therefore such a design is also contemplated that, wherein there is only center induction elements 26 (see figure other than protuberance 10 of the invention
14)。
The shape and orientation of guide portion 17 are also not limited to one embodiment in principle.For example, it is conceivable that replacing figure
Rodlike guide portion 17 shown in 15 outstanding is drawn using the direction of the mandrel line 11 thereto of the inner surface 9 from fiber guide element 1
Guide plate, this also will prevent the twist of fibre bundle 4 in contrast to direction of the supply T antidromic propagation.
About shown guidance mandrel, it should also be noted that, the central axis that they should preferably with fiber guide element 1
11 form angle δ (angle is only implied in Figure 15, with for clarity) preferably exists between 10 ° to 50 °
Between 20 ° to 40 °, particularly preferably between 25 ° to 35 °.
In general, it can also be advantageous for center induction element 26 in Figure 14 and 16 towards yarn formed element
21 end be located parallel to fiber guide element 1 central axis 11 extend the respective destinations region between guide portion 17 it
Between part on.This ensures that, fibre bundles 4 at least to connect simultaneously with guide portion 17 and center induction element 26 in some parts
Touching.
In addition, it should be pointed out here that, center induction element 26 should be at least in its inwardly directed region in fibre
