Description
Technical field
The present invention relates to a kind of yarn forming element of the yarning part for sir jet spinning machines, wherein the yarn forming element has a hole of entering distolateral, and have the discharge-channel for yarn, this discharge-channel is initial and extend along longitudinal axis in the inside of yarn forming element in entering the zone in hole.
Background technology
This yarn forming element is known by prior art, and is positioned in sir jet spinning machines in the described minor air cell.In the minor air cell, fibrous material drawing-off or homogenising is mostly by supplying roll to guiding and bear tangent vortical flow by the yarn forming element.The effect of this air-flow finally is that the outer fiber end of fibrous material can be twined round non-rotary core fibre (Kernfasern) in the zone that enters the hole of yarn forming element, and surrounds enduringly it.The yarn that produces by this way finally can be pulled out from yarning part by discharge-channel, and for example is wrapped on the bobbin.
In order to avoid as far as possible, be applied to torque on the outer fiber (input of air with enter the hole tangent) by air-flow and be delivered on the non-rotary core fibre, enter the large more options of diameter very little in hole.Therefore, WO 2006017948A1 for example is decided to be 0.8mm to 1.2mm entering bore dia.
But in this case, still can not avoid torque to be delivered on the core fibre from wrapper fibre, even this transmission of torque is very little.Therefore, core fibre and whole yarn all finally can form described false twisting.But, because the restriction of false twisting torque suspension has the direction of rotation identical with wrapper fibre, thus when unclamping, false twisting can cause the counter-rotating of fiber, and therefore can make fiber composite loosening to a certain extent, or make the yarn forfeiture fastness of producing.
Summary of the invention
The objective of the invention is, avoid the above-mentioned shortcoming of prior art.
This purpose is achieved by the yarn forming element with Patent right requirement 1 feature.
By the present invention's suggestion, the yarn forming element has at least one in the inside of discharge-channel and only turns round element, and this only turns round element narrows down the cross section of discharge-channel at least partly.In other words, exist element or the section bar of restriction discharge-channel of the inwall of yarn forming element, this element puts in the discharge-channel, and therefore for produced and provide contact-making surface by the yarn that discharge-channel is pulled out.Therefore, discharge-channel not only have cylindrical or truncated cone-shaped hole by the known shape of prior art.It but can have one or more forms be recess, protuberance, vaulted, crimp or other section bar only turn round element, they make the inwall of discharge-channel have the shape different from cylinder or truncated cone.
Different from cylindrical or truncated cone-shaped inwall is, this only turns round element finally is an obstacle, and it especially avoids core fibre to form false twisting.If they begin to reverse in entering the zone in hole and by its next yarn, then this yarn forcibly presents the longitudinal dilatation of slight curving (namely different from straight line).At this, it contacts with inwall, and therefore also with only turn round element and contact.At yarn with only turn round the formation that friction between the element prevented effectively that at last this from reversing or continue development, and therefore prevented the formation of false twisting.The result is that yarn penetrates discharge-channel, does not reverse and manifest error can not occur.
Be preferably in this context, the inwall of discharge-channel has the extension in the cross section perpendicular to longitudinal axis in the scope of only turning round element, and this extension is different from the trend of the circle of concentrating towards longitudinal axis.Discharge-channel is only turned round this or these in scope of element has profile, and this profile is different from cylindrical or truncated cone-shaped hole.Can't get rid of at this, certain circumferential part section of discharge-channel has circular-arc extension in the scope of only turning round element.But between them, have one or more projections, they radially put in the inside of discharge-channel from the circle of the imagination, and therefore are the obstacles (when forming false twisting can round the medial axis motion of discharge-channel and the yarn section section that contacts with inwall) of yarn ball diffusion.
More preferably, the yarn forming element has many elements of only turning round, and they are made of the protuberance of inwall.These protuberances constitute little nodular, chock shape, straight or crooked at this, and make inwall have superficial makings, and this superficial makings is different from smooth wallboard.This inwall for example also can have relatively large roughness (〉 RA0.5), so this inwall has the coarse protuberance of many generations.Go up usually herein and note also, this or these only turn round in the scope that element can be set directly at discharge-channel, this scope is connected to and enters the hole.Also may be considered that to have certain spacing between the element entering the hole and only turn round, wherein this spacing for example can be between 1mm to 20mm, preferably between 1mm to 10mm.
More preferably, only turn round element and consist of by connecing piece, it axially extends and extends in discharge-channel on the direction that is about longitudinal axis radially towards the longitudinal axis of discharge-channel.In the cross section of discharge-channel, only turn round this or these in scope of element and produced by this way a kind of ring gear, this ring gear has the gear teeth that point to inwardly, and wherein single gear teeth formation is only turned round element, and their toroidal inwalls from opposite directions radially extend to the inside of discharge-channel.Therefore, can prevent the yarn ball of appearance when being formed on false twisting forms, and therefore also prevent from forming false twisting, no longer can swing round the medial axis of discharge-channel or rotation because hold flexible yarn.These connect piece can have in its side that puts in discharge-channel inside smooth also or surface sharp-pointed or that tilt.These radially extending parts that connect piece are 0.1mm to 2mm preferably.Alternatively, described extending part also can be selected according to entering bore dia.For example advantageously, radially extending part is equivalent to enter 1/10 to 1/3 of bore dia.
In addition preferably, the yarn forming element have a plurality of forms be connect piece only turn round element, they are arranged on the inwall on the circumferencial direction of inwall evenly distributedly.Therefore, for the yarn of producing has produced an especially effectively rotation-obstacle, wherein connect the quantity of piece advantageously between 2 and 6.These radially extending parts that connect piece can fluctuate single connecing between the piece at this, also or can be invariable.These axial (about longitudinal axis of discharge-channel) that connect piece expand for example between 1mm and 30mm, preferably between 10mm and 20mm.In addition, these connect piece and usually also have the inclined-plane in their two ends, raise from the section's section that connects between the piece that is arranged on of the inwall of discharge-channel perhaps steppedly.
More preferably, discharge-channel have two transitional region interweave transition and two section's sections that diameter differs from one another, its termination is turned round element and is arranged in the transitional region.Especially in described zone, yarn only has lateral support, because pass through the internal diameter meeting partial loss of expansion and the contacting of inwall of discharge-channel.If now torque is applied on the yarn, then may form false twisting, but this false twisting can be avoided by one or more layouts of only turning round element.These are only turned round element and can only be arranged in the transitional region, or from this transitional region along or against the spinning direction extend at the axial direction of discharge-channel.
Equally preferably, discharge-channel has two transition that interweave in transitional region and two section's sections that diameter differs from one another, its termination is turned round in the zone that element preferably only is arranged on the larger section's section of internal diameter.As having mentioned, especially in the larger zone of internal diameter, exist danger, namely yarn has the flexible trend of appearance, and begins to swing (that is, yarn has spherical outline) on the circular orbit by the acting on of torque by the wrapper fibre transmission.If now this or these only turn round element and be arranged on specially in this zone, an obstacle then can be provided, yarn describedly can collide on this obstacle when spherical attempting to form.Therefore, can prevent rotation, and therefore prevent from forming the false twisting of not expecting.
More preferably, only turning round element is installed in the yarn forming element with the form of plug-in unit.In this case, only turning round element can be made of the material different from the yarn forming element, and in addition, from the manufacturing technology angle, the manufacturing plug-in unit is only turned round accordingly element than moulding in discharge-channel and more simplified.This plug-in unit can have basically columniform outline, so it can be installed in the corresponding hole of yarn forming element, and can consist of at last a position of discharge-channel.In addition, this plug-in unit has vault or recess in its outside, and they can concur with corresponding opposed the section at hole, in order to guarantee that plug-in unit is with respect to the stop of reversing of yarn forming element.
Equally preferably, only turning round element releasably links to each other with the yarn forming element.Therefore, for example after wearing and tearing, can change simply it.Equally, sir jet spinning machines can be rapidly be complementary with fibrous material to be spinned, and wherein also can change existing plug-in unit with the plug-in unit of coordinating mutually with new fibrous material when changing fibrous material.Only turn round element and can be screwed in, be clipped in the respective apertures of yarn forming element, or otherwise force closure or type link to each other with it in locking manner.If do not need the connection that can get loose, then can paste above-mentioned part yet.
Preferably, only turn round on the longitudinal direction that element is arranged on discharge-channel at least two, it is preferably spaced by the spacing holder that is arranged between them that this only turns round element.In this case, exist a plurality of respectively elements of only turning round spaced apart from each other in the inside of septal pathways, wherein singlely only turn round element and/or spacing holder exists with the form of plug-in unit again.Only turning round element and can for example press the form of ring gear and consist of separately, wherein the gear teeth single, preferred rounding radially extend to the inside of discharge-channel.
In addition preferably, spacing holder constitutes sleeve-shaped.This or these spacing holder can for example have the shape of hollow circular cylinder, so they have circular bearing-surface for the adjacent separately element of only turning round.Also have columniform outline if only turn round element, then it can push in the hole, center of yarn forming element, and wherein the spacing holder preferred orientation is between per two yarn forming elements.
In addition preferably, only turn round element for these at least two and define logical perforation for yarn, this logical perforation about longitudinal axis in the radial direction setting with offseting with respect to each.In this case, this only turns round element makes yarn in inner (about longitudinal axis) the radially deflection of discharge-channel, and can constitute mutually reverse setting, have an identical shaped plug-in unit.Should the logical cross section of boring a hole and also self can have circle, ellipse, lenticular shaped or corner angle are arranged.
In addition preferably, only turn round element and the yarn forming element constitutes one.In this case, can omit the afterwards connection of each part, its termination is turned round element and is for example made in the following manner, namely takes off the adjacent section of the inwall of discharge-channel afterwards.
More preferably, only turn round the surface section that element has at least one rounding.Therefore, can avoid damaging yarn, this yarn should specially only be turned round element with this or these and contact, in order to avoid forming false twisting.
Preferably, it is most advanced and sophisticated that the yarn forming element constitutes spinning, is used for the hollow spindle that is made of spinning tip and spindle body at least of sir jet spinning machines.In this case, the most advanced and sophisticated longitudinal extension position with several centimetres of spinning, and before sir jet spinning machines puts into operation, link to each other with the spindle body.This structure can be realized most advanced and sophisticated simply and fast the changing of spinning, and does not need to change whole hollow spindle.But alternative is, the yarn forming element also can have longer longitudinal extension position, and with other part without the hollow spindle that plays sir jet spinning machines with being connected.

The specific embodiment
Fig. 1 there is shown yarning part 14 by the sir jet spinning machines of prior art in the side-looking of partly cut-away.This yarning part 14 comprises fibre guide element 15, to be spinned and most fibrous material 16 that exists as the fiber band of drawing-off arrives at by this fibre guide element in the described minor air cell 17 of described yarning part 14, finally carries out original spinning process in this minor air cell.The drafter that is arranged on fibre guide element 15 fronts has been taken in described drawing-off usually, and the fiber band of drawing-off is by pull out roll to pulling out from this drafter.At last, fiber band preferably by be used as the supply roll to the roll of 18 usefulness to catching, this roll is to directly being connected on the fibre guide element 15 of should arranging as far as possible, to avoid wrong delay.
By the air-flow of being induced by spinneret 20, torque is worked being positioned at outside described wrapper fibre, and this torque finally is used for forming yarn.But simultaneously, this torque also is delivered to and is positioned on the inner core fibre, and this core fibre should keep not reversing in principle.This torque can make core fibre also place oneself in the midst of among the rotation in the disadvantageous situation, the yarn 22 that therefore is arranged in discharge-channel 4 also can begin rotation.But this rotation can not develop without restriction, pulls out parts (for example to pull out the right form of roll) because arrange in the interface of discharge-channel 4, and this pulls out parts clip ground delivered yarn 22.The result is, entering the described false twisting of region generating of 2 back, hole, i.e. reversing of yarn 22, and this reverses in it continues the process of transportation and again unclamps.But, finally can cause the loose of wrapper fibre, and the yarn fastness is degenerated.
As shown in Figure 2, by the effect of described torque, can produce the yarn trend, this yarn trend has one or more bendings with respect to longitudinal axis 3.Yarn 22 contacts the inwall 5 of discharge-channels 4 in most of positions, and skims in its inner circumferential, wherein finally can produce the false twisting of not expecting.
For fear of forming described false twisting, now by the present invention's suggestion, what yarn forming element 1 had that at least one is arranged on discharge-channel 4 inside only turns round element 6, and it narrows down the cross section of discharge-channel 4 at least partly.From Fig. 3 to 7, can draw this or these only turn round the operation principle of element 6 and possible embodiment.
Fig. 3 shows the exemplary moulding of only turning round element 6 by of the present invention.In the embodiment shown, only turn round element 6 and be made of equally distributed protuberance 7 in the scope of a plurality of inwalls 5 at discharge-channel 4, they can for example constitute little nodular.May be considered that also described protuberance 7 is by selecting sufficiently high roughness to realize for inwall 5.
If transmission of torque is to core fibre now, then yarn 22 consists of bending shown in Figure 2, and namely yarn 22 contacts with the element 6 of only turning round that is shaped as protuberance 7 in the scope that enters hole 2.Because swell and 7 avoided the motion (protuberance 7 finally be an obstacle, it must by yarn 22 constantly be skimmed over) of yarn 22 on the circumferencial direction of inwall 5, so also can prevent from forming false twisting.Only turn round element 6 and therefore produced bearing-surface, the torque that is delivered on the core fibre can be by this bearing-surface interception.The generation of false twisting is avoided, and yarn 22 has than the better fastness of prior art.
Fig. 4 shows aspect structure and realizes by another possibility of only turning round element 6 of the present invention.In an illustrated embodiment, that only turns round that element 6 has that four longitudinal axis 3 about discharge-channel 4 radially stretch out inwardly connects piece 8, and the quantity that wherein connects piece 8 changes.As in conjunction with appreciable by the cutaway view (not having identical yardstick) of line A-A', connect on the circumference that piece 8 is arranged on discharge-channel 4 evenly distributedly.In addition, they and yarn forming element 1 constitute one, wherein also can be divided into independent part.In the running of sir jet spinning machines, connect piece 8 and consist of now described obstacle, be used for yarn along the course of inwall 5, therefore can avoid reliably the formation of false twisting.
At last, connect in the transitional region 9 between the section's section with different-diameter that piece 8 is arranged on discharge-channel 4.Certainly, also can consider before or after this zone, to position or extend.
Fig. 5 shows corresponding structure.At this, connect piece 8 from transitional region 9 along discharge-channel 4 direction extend.The length that connects piece 8 is transformable at this, and can have a plurality of centimeter length.Connecing piece 8 also can be interrupted by intermediate cavity.
At last, from Fig. 6 and 7, can draw two other favourable improvement project of the present invention, compare with previously described scheme, be characterised in that at the element 6 of only turning round shown in this it and yarn forming element 1 are not to make integratedly, but make as independent plug-in unit 10.These plug-in units 10 for example separate by the spacing holder 11 of the sleeve-shaped that illustrates, and shift onto from below in the middle hole of yarn forming element 1, and correspondingly fix.
Fig. 6 show have a projection only turn round element 6, and only turn round element 6 by Fig. 7 constitute half the hook moon shape, and limit lenticular logical perforation 12 by the middle hole of yarn forming element 1.By the biasing of logical perforation 12 shown in two, yarn 22 last experience zigzaggeries, this route can prevent the formation of false twisting reliably.In addition, only turn round the surface section 13 that element 6 also has rounding among Fig. 7, in order to avoid the damage of yarn 22 therebetween in deflection.
In addition, the present invention is not limited to the embodiment that illustrates.All combinations of described single feature all are contents of the present invention, as they shown in claim, description and the accompanying drawing or describe the same, need only and be combined in accordingly technical elements and look like feasible or significant.
