Description
The present invention relates to a kind of yarn forming element of the spinning station for open-end spinning frame, wherein yarn forming element have front side enter hole and for the discharge-channel of the yarn manufactured by spinning station, described discharge-channel originates in and enters the region in hole and extend yarn forming element is inner.The open-end spinning frame with at least one spinning station has been described in addition, wherein spinning station has the required entrance of fibrous material to be weaved and in the direction of spinning, is arranged on the minor air cell in entrance downstream, and have to put in minor air cell and have and enter hole and for the yarn forming element of the discharge-channel of the yarn manufactured by spinning station, and at least one leads to the spinning jet nozzle of minor air cell, by entering the region generating spiral type air-flow in hole in described spinning jet nozzle Ke minor air cell.Finally, a kind of method of manufacturing yarn by the spinning station of open-end spinning frame has also been proposed, eddy airstream is provided wherein in the region that enters hole of spindle shape yarn forming element, in the minor air cell at spinning station, to the fibrous material being formed by filament, by it, the part in fiber is reeled in the first rotation direction of seeing with top view visual angle around fibre core, thereby generation yarn, and wherein by the yarn of generation being emitted with discharge-channel minor air cell's adjacency, yarn forming element.
To have the yarn forming element that enters hole and discharge-channel thereafter in front side be known in the prior art and be used to guide in the inside, minor air cell of open-end spinning frame the fiber that will send into of fibrous material to be weaved and guiding entering the yarn of being made by fiber in the region in hole.While producing yarn, conventionally by feed roller, warp yarn director element is also run into tangential eddy current there by stretching, extension or the minor air cell of fibrous material introducing uniformly.Finally, the fiber outer end that this air-flow causes fibrous material yarn forming element enter bore region in around untwisted core fibre, reel and these core fibres of looping always.The yarn of manufacturing in this way is finally emitted and for example can be wound up into bobbin from spinning station by discharge-channel.
Although it is feasible that the method has been proved to be since for a long time, the intensity that the yarn of correspondingly producing has is not also best conventionally.Therefore task of the present invention is, improve the known yarn forming element of prior art and equipped the open-end spinning frame of described yarn forming element, and improve the method for producing yarn by open-end spinning frame, to can produce the extra high yarn of yarn strength by this open-end spinning frame.
The yarn forming element that solves now this task is characterised in that, has arranged spiral director element in discharge-channel, by it, can allow the yarn false-twisted (Falschdrall) by discharge-channel.The known yarn forming element of prior art always has discharge-channel, described discharge-channel has cylindrical or Frusto-conical wall, so that the least possible in entering bore region, frictionally the untwisted fibre core being intertwined of the wrapper fibre by being caught by air-flow (causing the fiber outer end of the fibrous material of minor air cell) is ejected.In contrast, core of the present invention is to change at least in part the known form of discharge-channel, and object is to force Sha Xian – and known regimes Xiang anti-– false twisting.This refers to that yarn is around its longitudinal axis rotation, and wherein director element unclamps again by rear rotation.From wrapper fibre during spinning discharge-channel enter bore region in the permanent twisting that obtains different, according to director element of the present invention, only generate interim twisting, its at reel for yarn around just unclamping voluntarily before.
This interim false twisting tool in region after discharge-channel enters hole has the following advantages:
The air-flow that the yarn end that side direction is outstanding from be introduced into the fibrous material minor air cell during spinning is tangentially acted on is caught, and around almost untwisted core fibre (around the fiber of fibrous material, it is inner that described fiber mainly or is all positioned at same fibrous material, and therefore air-flow can not enter), result produces the yarn with true sth. made by twisting.In this process, wrapper fibre is entering in bore region core fibre (another title: fibre core) apply torque, thereby dangerous below making when not according to director element of the present invention, fibre core equally also rotates in sun colyliform fiber (Fasersonne) region on airflow direction.But described in be rotated in after entering hole and unclamp again (so this is also a kind of false twisting) because only effect beyond discharge-channel of so-called torque.But by the reverse rotation of correspondingly unclamping relevant core fibre to false twisting, also can make the wrapper fibre of finished product yarn to returning the large section of (contrary with airflow direction) rotation one.Consequently likely cause fibre bundle loosening, thereby cause yarn strength to decline.
In discharge-channel, by spiral director element according to the present invention, can less desirable effect be balanced out by simple mode now.The present invention is simultaneously based on such fact, at (helical form) vortex, through out-of-date, also can for example, to filamentary material (yarn of producing by open-end spinning frame), produce torque, causes described filamentary material around its longitudinal axis rotation.Its reason is the frictional force between filamentary material and director element surface.If corresponding director element is placed in discharge-channel, finished product yarn will rotate, and described rotation can produce torque to the fiber entering in bore region of discharge-channel upstream again.If spiral director element has such direction of rotation, the direction of rotation of the air-flow that this direction of rotation produces with spinning jet nozzle by minor air cell is contrary, can see following effect:
The eddy current that wrapper fibre produces because of spinning jet nozzle produces torque to the core fibre entering in bore region at discharge-channel, and this torque acts on airflow direction.Yet a part for the yarn in spiral director element region produces torque to core fibre, this torque acts on (prerequisite is that the direction of rotation of this spiral director element is contrary with the direction of rotation of air-flow certainly) in the reverse direction.The core fibre of result in entering bore region rotates up in the side contrary with wrapper fibre direction of rotation, and causing wrapper fibre is not around untwisted fibre core, but around pre-fibre core of twisting.
If the yarn of producing in this way leaves spiral director element region, the core fibre rotation that director element causes can be unclamped again, that is to say that the side around core rotates up core at wrapper fibre.But while not rotating together around the wrapper fibre of fibre core, fibre core can not rotate, so wrapper fibre at present also can be toward looping direction (extraly) rotation.So wrapper fibre can be tightlier more firmly around fibre core (it is the same when untwisted in this stage), thereby generate especially firmly yarn.
To before elaborating as follows according to the CONSTRUCTED SPECIFICATION of spiral director element of the present invention, what important affair first illustrated herein is, yarn forming element can be the hollow spindle that puts in minor air cell, also can only refer to that spinning is most advanced and sophisticated, it forms corresponding hollow spindle together with supporting the most advanced and sophisticated spindle that spins.
But particularly advantageously, yarn forming element comprises having that to enter the spinning in hole most advanced and sophisticated and support the most advanced and sophisticated spindle of spinning, wherein discharge-channel the most advanced and sophisticated inner and spindle of spinning inner extend and wherein spiral director element be arranged in the most advanced and sophisticated inside of spinning.Therefore,, by suitably selecting spinning tip also can use spiral director element, the material that the geometry of this spiral director element (winding number, pitch, pitch etc.) can be to be weaved with each matches.Also can realize guiding by insert corresponding, that have spiral director element, this will be described in detail in the back, and condition is that manifold hollow spindle may be simple especially, and the reason tip that is to spin can removably be connected with spindle.Finally it is also contemplated that, director element is only arranged in spindle or is additionally arranged in spindle, be connected to spinning most advanced and sophisticated.
Particularly advantageously, discharge-channel has the part of spiral extension, and this part forms the spiral director element of yarn.In this case, discharge-channel itself is as spiral director element, and without re-using extra element.In this situation, first lower discharge-channel for example extends (reeling without corresponding) segment distance from entering hole straight line, and then is transitioned into sweep.Discharge-channel is finally spiral extension in this region, and wherein pitch is roughly even, but can be also increase progressively or successively decrease.The yarn forming element that result obtains has the discharge-channel extending in inside, and this passage has again such part sections, and it extends in a tubular form and extends through yarn forming element according to the screw line of imagination.Finally at spiral part place, be and then provided with again linearly extended discharge-channel part.Spiral part also can, directly in abutting connection with entering hole, so just can be saved above-mentioned linear pattern start-up portion.
Yet, except the spiral shape of discharge-channel, when spiral director element consists of the independent director element that is spiral extension, be also favourable.In this case, discharge-channel itself can be also straight line, for example, design the form of pore-forming, wherein also can additionally arrange one or more director elements, and they can guarantee to produce described false twisting.In other words, spiral director element can form by being arranged in the insert of discharge-channel inside, described insert regularly (by gluing, welding, soldering etc.) is connected to yarn forming element, or removably (is for example connected by screw) and is connected to yarn forming element.Owing to manufacturing separately insert and discharge-channel, so the integral body manufacture of yarn forming element has been greatly simplified from structure.
Also advantageously, insert is in the face of having the screw type and recess of flute profile preferably on the surface of discharge-channel inwall, and this recess forms the spiral director element of spiral channel form together with inwall adjacent part.In this case, insert does not have corresponding spiral-shaped orifices, and described hole is considered the introduction channel of yarn.In fact, above-mentioned passage be due to insert surface part (boundary surface form of recess) and answer in contrast, near the mating surface acting in conjunction generation of the yarn forming element inwall of insert.Method that described recess can be polished by material by simple mode is for example introduced in matrix cylindraceous, yet consider and formed spiral channel, just for example, without having reprocessed the depressed part that is used for holding finished product insert (hole shape) of yarn forming element.
In addition, also maybe advantageously, director element is configured to line rolling piece.Described rolling piece can be made into insert equally, and preferably has the minor diameter that is no more than 1mm, to guarantee corresponding, to allow yarn generation false twisting deflection.Now, as all other according to director element of the present invention, the pitch of coiling can be constant in the part extending longitudinally of rolling piece, but also can change in part extending longitudinally, for example (equably) increase or reduce.
In addition when the number of turns of spiral director element is between 0.2 to 5, in the time of preferably between 1 to 3, can be favourable.Number of turns is many causes the rotation that core fibre is strong especially in entering bore region, and number of turns causes the friction between yarn and director element little less, thereby makes the outer fiber of yarn only be subject to minimum mechanical stress.Even if for example director element can only have half coiling, but it has the spiral contact-making surface for yarn, that is to say that described contact-making surface has sweep and extends on the longitudinal direction of residue discharge-channel, thereby make to produce screw line or spiral curve.
When entering spacing between hole and spiral director element between 1mm and 10mm, in the time of preferably between 1mm and 5mm, this is favourable.It is favourable that spacing is tried one's best little, because the torque for being produced by director element should act on core fibre exposed in entering bore region, thereby core fibre is rotated in exposed fiber end along air-flow opposite direction.But certain spacing is favourable, to form the facing stop of the insert with director element.
Also very advantageously, the spiral director element of seeing with top view visual angle has presented a circular arc, and this circular arc has central angle alpha with respect to the longitudinal axis of yarn forming element, and its number of degrees are at least 60 °, and preferably at least 120 °, particularly preferably at least 180 °.Therefore as previously mentioned, director element does not have a complete circle coiling, but wherein because therefore curved shape likely produces corresponding false twisting.
Advantageously likely, insert consists of a plurality of, preferred similar discrete component finally, and wherein said discrete component with power, coordinates to each other and/or the mode of form fit connects.In other words, also can use " basic rolling piece ", this rolling piece is constructed as follows, and it can be connected with the mode that one or more other basic rolling pieces coordinate with form fit and/or power.Result is to produce thus such possibility, and the length of insert or the number of turns of discharge-channel are because the number of discrete component connected to one another changes.Discrete component for example has one or more depressed parts and on relative front, has one or more expansions in its front simultaneously.If two discrete components link together, one or more expansions of one of them discrete component mesh into the depressed part of adjacent discrete component.Described one or more expansion or depressed part preferably have non-circular cross section at least one region, thereby the discrete component connecting together can not be reversed mutually.This shows, discrete component connected to one another can form the discharge-channel of stepless, and this discharge-channel extends along whole discrete component.Possible in addition, insert is comprised of initial, end piece and one or more identical middleware, and wherein initial has entrance inclined-plane, and end piece has outlet inclined-plane.The quantity final decision of middleware the total length of insert (wherein also can not use middleware).Last insert also can be comprised of a plurality of identical discrete components, and these discrete components have respectively entrance inclined-plane and outlet inclined-plane.Meanwhile, the profile on entrance inclined-plane and outlet inclined-plane preferably coordinates as follows, makes it when connecting discrete component, form form fit and guarantee described anti-torsion.
Finally, open-end spinning frame according to the present invention is characterised in that, in discharge-channel and/or after exporting with discharge-channel, arranges spiral director element, by it, makes yarn produce false twisting.Can be with reference to description above about possible form of implementation and advantage, wherein all single features can be combined use, only otherwise occur obvious contradiction.In addition also maybe advantageously, except described director element or substitute described director element, after spiral director element is arranged in to discharge-channel outlet.
Particularly advantageously, at least one spinning jet nozzle is tangential orientation with respect to entering hole, thereby make can generate air-flow (seeing that with top view visual angle described air-flow has the first direction of rotation) by spinning jet nozzle, also can make spiral director element there is coiling (seeing that with top view visual angle its direction of rotation is in the second direction contrary with the first direction of rotation).Finally produce thus two torques, the torque energy wherein being produced by air-flow guarantees, the uncovered fibres end that is introduced into the fibrous material of minor air cell is reeled around core fibre in the first direction of rotation, and rotates in the opposite direction by the torque being produced by director element.Therefore in uncovered fibres, be used as wrapper fibre before fibre core placement, just to a certain extent core fibre strained in advance.Finally, after passing through guide channel, the whole yarn in the present invention main side toward wrapper fibre around fibre core rotates up, thereby makes the coiling of wrapper fibre be strengthened and the rotation of fibre core is unclamped.
Last according to the invention provides a kind of method of manufacturing yarn by the spinning station of open-end spinning frame, in the method, yarn is subject to torque after entering into discharge-channel, this torque causes yarn to rotate in the second direction of rotation around its longitudinal axis, wherein the second direction of rotation with top view visual angle, see contrary with the first direction of rotation, and wherein because yarn can produce false twisting around the rotation of its longitudinal axis.Can in discharge-channel and/or after discharge-channel, to yarn, apply torque.Can give birth to torque by pneumatic real estate in addition, but also can produce torque by mechanical organ.
Therefore for example advantageously, by spiral director element, produce torque, this director element is arranged in discharge-channel and/or after the outlet of discharge-channel.Again can be with reference to description above about the architectural feature of director element, all feature all can single realization or is realized with any combination here simultaneously, as long as no obvious contradiction.
Other advantage of the present invention is described in the following embodiments.In figure, show:
Fig. 1 is according to the partial cut away side views in the open-end spinning frame cross section of prior art.
Fig. 2 is in the yarn forming element (a) by known) and by according to yarn forming element of the present invention (b)) time the cross section of each yarn,
Fig. 3 is according to the partial cut away side views of yarn forming element of the present invention,
Fig. 4 be another according to the partial side view of yarn forming element of the present invention, and
Fig. 5 is side view and the top view of the middleware of many parts insert, and described many parts insert is used for according to yarn forming element of the present invention, and
Fig. 6 is the side view according to spiral director element of the present invention.
Fig. 1 shows the partial cut away side views at the spinning station 2 of known open-end spinning frame.Described spinning station 2 comprises the fiber guide element 21 with entrance 19 and guide channel 15, wait that the fibrous material 20 of weaving and conventionally existing with drawing of fiber bundle form enters the minor air cell 18 at so-called spinning station 2 by described guide channel, actual spinning process here occurs again.Conventionally by the drawing frame that is connected to fiber guide element 21 upstreams, stretched, by traction roller to the fibre bundle being stretched is pulled out from drawing frame.Finally, fibre bundle is preferably caught 16 by feed roller, and it should be tried one's best and directly be arranged in after fiber guide element 21, to avoid wrong crooked.
When the guide channel 15 of fibrous material 20 via fiber guide element 21 passes through after this fiber guide element 21, it enters a plurality of, conventionally tangentially to enter the spinning jet nozzle 7 of minor air cell 18 effective coverages.If apply overvoltage to described spinning jet nozzle by corresponding supply pipe 14 during spinning, can produce eddy airstream, described eddy airstream can divide mobile around the top that puts in the hollow spindle of minor air cell 18.If outwards outstanding fibre end is caught by described air-flow, fibrous material 20 is in the required rotation of the region generating that enters hole 3, and result generates required yarn 5, and described yarn finally can be by entering hole 3 and discharge-channel subsequently 4 ejects from minor air cell 18.
Except the hollow spindle of single type, the hollow spindle of many parts is also known for a long time, and as shown in Figure 1, described hollow spindle is comprised of spindle 10 and the spindle tip being attached thereto.Described connection for example realizes at the join domain schematically showing, and wherein can realize the connection that form fit and/or power coordinate.Enter region around, hole 3 because of abrasion deformation after, spinning most advanced and sophisticated 9 finally can be independent of spindle 10 and change.This is applicable to following situation too, and hypothesis will be changed the situation of fibrous material to be weaved 20.
During spinning, fiber end outside, that form so-called sun colyliform fiber 22 can be subject to the impact of the air-flow that produced by spinning jet nozzle 7, and described air-flow applies corresponding torque by its tangent line at fibre end.This torque finally also acts on untwisted fibre core 23, and therefore described fibre core is also attempted to rotate on airflow direction.Yet this rotation of fibre core 23 will be avoided.Reason is this fact, and potential being rotated in discharge-channel 4 of fibre core 23 can be unclamped again again, because unstable torque of rotating is worked here.Therefore just may in discharge-channel 4, make whole yarn 5, fibre core 23 counter-rotates, so wrapper fibre 24 is also with the contrary direction rotation of direction of rotation with wrapper fibre 24 fibre end of fibre core (=around).In this case, wrapper fibre 24 can unclamp again a large section, thereby causes yarn 5 intensity to decline.
In order to eliminate this impact and to make wrapper fibre 24 produce extra twisting in the direction of its existing rotation causing due to air-flow, what according to the present invention, propose is, in discharge-channel 4, (or as required also can after the outlet 6 of discharge-channel) arranges spiral director element 8, by it, make to produce false twisting (i.e. rotation, described rotation is unclamped again after not being fixed on guiding) by the yarn 5 of discharge-channel 4.Meanwhile, the direction of rotation of spiral director element 8 is contrary with the direction of rotation of air-flow, thereby makes to apply torque to offset the torque applying forming the fibre end of sun colyliform fiber 22 by air-flow on the core fibre of director element 8 in entering 3 regions, hole.In other words, internal fiber core 23 rotates up in the contrary side of the direction of rotation of the fibre end of catching with air-flow.
Described effect is shown in Figure 2, represents the direction of each fiber in figure with the hacures of corresponding orientation.
As from Fig. 2 a) as shown in and in describing the accompanying drawing of prior art, can find out, the fiber that forms fibre core 23 is parallel in entering region above, hole 3 (region " I "), himself does not rotate (its uncovered fibres end moving around fibre core 23 as sun colyliform fiber 22 in this region is not illustrated and is inessential for understanding yet).When fibre core 23 is entered to discharge-channel 4 inside by entering hole 3 tractives, exposed fiber end is finally understood around fibre core 23, thereby makes to generate in principle image as shown in region " II " in Fig. 2 a.Because discharge-channel 4 is configured to hollow cylinder shape or frustoconical shape on known spinning station 2, therefore the yarn 5 in another region (" III ") is not further rotated before the outlet of discharge-channel 4, thereby makes to form the fiber of fibre core 23 and the orientation of corresponding wrapper fibre 24 without any change.
In contrast, the fiber of formation fibre core 23 is having rotation (referring to Fig. 2 b) after entering hole 3 (region " II ")).Its reason is the torque of having described, and described torque is delivered to the yarn 5 reversing by director element 8 according to the present invention on fibre core 23 in entering 3 regions, hole.Because described torque reaction is in the torque being applied to by air-flow on exposed outer fiber end, the rotation of the fibre core 23 existing in region " II " is contrary with the rotation of wrapper fibre 24.
Finally, yarn 5 arrives director element 8 region " III " below.Fibre core rotation is finally here unclamped, and this is because for example, by corresponding pulling device (pulling device of traction roller to form) that spinning station 2 yarn 5 below is fixing as follows, can not proceed rotation by pulling device.So have the thread segment of false twisting the closer to pulling device, contrary torque will be worked, and fibre core 23 reverse rotations are finally guaranteed in this contrary torque.But meanwhile, wrapper fibre 24 also can rotate up same side, thereby unidirectional rotation is strengthened.By the open-end spinning frame according to the present invention final result of processing that spins, be to obtain especially firmly yarn 5.
Fig. 3 shows from structure and realizes according to the possibility of director element 8 of the present invention.In the embodiment shown, yarn forming element 1 has and is roughly columniform insert 12, and recess 13 screw type and structure grooving extends on the surface of this insert 12.This recess forms spiral channel with together with the adjacent part of the wall of centre bore again, and this passage is for example transitioned into inclined-plane at two end faces of insert 12, and yarn 5 is entered described passage and can be left this passage again by inclined-plane.Spiral director element by yarn 5 finally produces false twisting the part 11 (it inwardly limits by recess 13) of the spiral extension of discharge-channel 4 is inner, but it unclamps again below and therefore makes wrapper fibre 24 more firm at director element 8, as shown in Fig. 2 (region " III ").
Purely for fear of doubt, here also to point out, spinning jet nozzle shown in Fig. 17 is according to should tangentially entering as follows minor air cell 18 in the yarn forming element 1 of Fig. 3, make described spinning jet nozzle produce air-flow, this air-flow (entering hole 3 with top view visual angle) rotates counterclockwise, so that the core fibre of guaranteeing to enter in 3 regions, hole rotates in the opposite directions of expectation with the fibre end that forms sun colyliform fiber 22.
In addition likely advantageously, described insert 12 is configured to manifold.For example Fig. 4 and Fig. 5 show corresponding form of implementation.
As can be seen from these figures, insert shown in 12 comprises having initial 16 of entrance inclined-plane 25, have the end piece 28 on outlet inclined-plane 27 and be arranged in the middleware 29 between the two.Initial 26, middleware 29 and end piece 28 correspondingly have the intermeshing anti-torsion of contact-making surface 30 and form fit ground abutting one another under embedded installment state.
As can be seen from Figure 5, anti-torsion for example can be realized by the interaction of corresponding extension 31 and corresponding depressed part 32.For instance, the end region of middleware 29 in two end face has extension 31 and has corresponding depressed part 32 in its opposing end surface region.If in the embodiment shown in fig. 4, initial 26 also has corresponding depressed part 32 on its end face down, middleware 29 can by its extension 31 form fit connect together with initial 26.Also can correspondingly be connected with end piece 28, prerequisite is that at it, the contact-making surface 30 facing to middleware 29 has the extension corresponding with the depressed part 32 of middleware 29 31 to end piece.
Finally, the advantage of many parts insert 12 is, the quantity of the middleware 29 using can change according to corresponding procedure parameter (fibrous material 20 to be weaved, spinning speed etc.).If end piece 28 is directly coupled with initial 26, obtain short especially discharge-channel 4, but this discharge-channel can extend by correspondingly inserting one or more middlewares 29.
Certainly also possible, initial 26, end piece 28 and middleware 29 are configured to the same, thereby corresponding insert 12 can be comprised of identical primary element again.What can imagine especially in this is, each primary element has entrance inclined-plane 25 and outlet inclined-plane 27 (being similar to the insert 12 in Fig. 3), wherein the entrance inclined-plane 25 of two primary elements adjacent under installment state and outlet inclined-plane 27 abut one another, and make mutually to reverse and to produce continuous discharge-channel 4.
Finally, Fig. 6 shows and realizes according to the another kind of possibility of director element 8 of the present invention.
Do not use the insert 12 shown in Fig. 3, it is also possible by line rolling piece 17 (except the rolling piece being made of metal, certainly also can use the rolling piece of other material), yarn 5 being turned to.The diameter of line rolling piece 17 should be less, and its diameter is less than the diameter of the yarn 5 that will produce, to prevent that yarn 5 from not generating false twisting by line rolling piece 17.
Finally, rolling piece can enter with the form of insert 12 spinning tip 9, enters in the spindle 10 that supports spinning most advanced and sophisticated 9, enters in the hollow spindle of single type, or also can (from spinning direction) be arranged in yarn forming element 1 downstream.The number of turn, pitch or the thickness of rolling piece will be selected according to professional person's judgement simultaneously, thereby make the description in Fig. 6 only be regarded as example.In any case but yarn all can be because spiral director element produces rotation, this can unclamp again after being rotated in director element.
The present invention is not limited to embodiment shown and that describe.Change in the framework of Patent right requirement as the combination of feature be also possible, even if these features are to describe and describe in different embodiment.
