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 extends at the regional endogenous origin that enters the hole and in the inside of yarn forming element.In addition, a kind of method of preparing joint process (Anspinnvorgnang) at the yarning part of sir jet spinning machines has also been described, wherein yarning part comprises yarn forming element and the fibre guide element before the spinning direction is arranged on the yarn forming element, this yarn forming element has for the discharge-channel at the yarn of yarning part internal pair production, and this fibre guide element has the guide channel be used to the fiber band that transfers to yarning part.
Background technology
Common way is after yarn breakage appears in sir jet spinning machines, the wind that again was received partly yarn in the yarn end of the yarn of the internal pair production of the yarning part of sir jet spinning machines before yarn breakage launches, and guides by yarning part against original winding direction.Yarn at first passes through the discharge-channel of yarn forming element at this, by air-flow targetedly the fiber band of input is reversed in spinning process on its outer surface, and therefore forms yarn.By being arranged on after aperture on yarn forming element distolateral leaves discharge-channel, this aperture is used for the yarn produced as entering the hole during spinning in the yarn end, and it at last must be through so-called fibre guide element.During conveying fiber, this fibre guide element can be avoided in spinning process, fiber band or the yarn that in this stage, produces entering the inside that far spreads to arbitrarily the fibre guide element of reversing that occurs in the scope of hole, and cross the fibre guide element and spread away.
Realize the described back coupling process of yarn end by air-flow, this back coupling process is until provide in the supply roll and the scope between the fibre guide element of fiber band to be spinned, this air-flow enters discharge-channel by independent air duct with wedge angle, and leaves this discharge-channel by entering the hole.For example learn this solution from DE102008 050 874 A1.In most of situation, realize the back coupling of yarn end in the scope between supply roll and fibre guide element without problems by described air-flow, but can not fully debug situation.
Summary of the invention
Therefore the objective of the invention is, advise a kind of yarn forming element of the spinning chamber for sir jet spinning machines, and advise a kind of method of preparing the joint process, they can more effectively realize the back coupling of yarn end in a scope, the yarn end contacts with fiber band to be spinned in the joint process in this scope.
Aspect equipment and technology, this purpose is achieved by the yarn forming element with Patent right requirement 1 feature.
By the present invention, the yarn forming element has injection channel, and it extends in the inside of the wallboard that surrounds discharge-channel of yarn forming element at least partly, and leads to tap, and this tap is positioned at the scope of the outer surface of yarn forming element.This injection channel or tap namely can produce air-flow in this preferred like this design when packing air into to injection channel, this air-flow begins to extend in the distolateral direction of yarn forming element at least partly from tap, and this is distolateral to have the hole of entering.The yarn forming element is often referred to Yarn-spinning spindle, i.e. most object longitudinal, that have described discharge-channel, and having of it enters the distolateral of hole and extends in the so-called minor air cell of yarning part according to corresponding structure.In spinning process, in entering the scope in hole, produce the air-flow of rotation by corresponding spinneret, mostly by the supply roll ribbon-like fibre material that provides is caught by this air-flow.This air-flow makes the fiber rotation that is positioned at the outside at least, and the result produces yarn, and this yarn can pull out from the minor air cell by discharge-channel.Therefore the yarn forming element both can refer to the hollow spindle of monomer, but only referred to that also the spinning of this spindle is most advanced and sophisticated, namely referred to section's section spindle the place ahead, that preferably can get loose and arrange, and this section has the hole of entering.
In all cases, the yarn forming element has described injection channel, can produce air-flow by it, and therefore this air-flow direction along inlet port under the confined state of yarn forming element also extends along the direction of above-mentioned fibre guide element.If present yarn end is moved so far away for joint process subsequently towards the spinning direction by discharge-channel, so that it enters in the minor air cell, then it is caught by described air-flow, this air-flow extends to the guide channel of the fibre guide element of having mentioned from the surf zone of the sensible yarn forming element of tap always, and leaves yarning part by it.Therefore, this air-flow begins to have obtained the path trend from the hole that enters of discharge-channel, and the yarn end also should obtain this path trend, in order to arrive in the joint area in the outside of minor air cell.In other words, produce air-flow, this air-flow is caught the yarn end in entering the scope in hole, and imports in the guide channel of fibre guide element, and moves at last the fibre guide element and supply roll in the scope between (or similar supply equipment).Therefore the result is, also can use the fibre guide element, its guide channel arranges about the axialy offset ground of discharge-channel, preventing that yarn distortion from spreading in the zone of outside, minor air cell always, because the yarn end is by by the air-flow of the present invention ladder through existing in this case reliably.
In addition advantageously, the yarn forming element has at least one at the inner air duct that extends of wallboard, this air duct leads in the discharge-channel with wedge angle and like this design, namely can produce sensing in discharge-channel inside when packing air into to air duct and enter the air-flow of hole direction.In this case, only just can realize the yarn back coupling by yarning part by two air-flows, the air that wherein flows into the discharge-channel from air duct moves in the scope of minor air cell the yarn end always, and the air of discharging from injection channel can be guaranteed the guiding of yarn end, and described guiding finally is conducive to the yarn end and imports in the fibre guide element.Because two air-flows finally leave the minor air cell by the guide channel of fibre guide element, so exist fluid in this scope, the flowing velocity of its flowing velocity brake specific exhaust emission channel interior is higher.Especially high tractive force has been born in the yarn end therefore in the inside of fibre guide element, and therefore stays in this scope under stress, thereby can guarantee safe back coupling.
Especially advantageously, injection channel and air duct lead in the common air feed passage.The yarn forming element for example has the annular chamber that is arranged in the wallboard for this reason, and this annular chamber can link to each other with corresponding superpressure source in yarning part according to structure.If applied corresponding superpressure now before the joint process, then air both also flowed by air duct by injection channel, and this air duct leads in the discharge-channel of yarn forming element.Described air-flow is unified before the fibre guide element in the minor air cell at last, therefore at this region memory in higher air velocity, this air velocity guarantees that the yarn end more firmly imports in the guide channel of fibre guide element.
Very advantageously, injection channel and/or air duct constitute the hole.At this, the hole that consists of injection channel begins basically to extend in the spinning direction from tap, namely also pulls out in spinning process on the direction of yarn.If the back coupling of yarn end expects, then therefore this hole air of can packing at last produces air-flow against the spinning direction.This air-flow begins to extend along the guide channel of fibre guide element from tap at last.Usually emphasize herein at last can certainly have a plurality of in the above-mentioned passage by yarn forming element of the present invention.
In addition advantageously, injection channel at least part extends as the crow flies, and the longitudinal axis of section's section of straight extension and discharge-channel surrounds an angle, and this angle is between 1 ° and 10 °, especially between 1 ° and 5 °.Especially has conical outer surface when the front region of yarn forming element (i.e. the section's section that the hole links to each other that enters of direct and discharge-channel), then the described orientation of injection channel has been guaranteed, air-flow begins to extend along the direction that enters the hole on the outer surface of yarn forming element 1 from tap.In this scope, air is caught yarn end to be feedback at last, and the yarn end is converged, and carries this yarn end by the guide channel of fibre guide element.Alternative is, also possible at last is that injection channel and discharge-channel be arranged in parallel.
Equally also advantageously, the yarn forming element has matrix and cover component, wherein injection channel is made of the corresponding counter surface of the depression of the preferred channel form of the outer surface of matrix and cover component that (certainly alternative is, this depression also can be arranged on the inner surface of cover component, or be arranged in two elements, as long as matrix and cover component corresponding relative and section's section formation of putting are by injection channel of the present invention).Especially in the problematic situation in manufacturing technology aperture (for example the yarn forming element, it is made by pottery wholly or in part), then in matrix and cover component, provide above-mentioned parts.In this case, but the injection channel milling is on the surface of matrix, therefore at first produce a kind of groove, this groove preferably extends (that is, depression and discharge-channel are overlapping at least within the specific limits) by discharge-channel in the side view of yarn forming element in the plane.If matrix links to each other with cover component at last, then postpartum Omnidirectional enclosed injection channel.Cover component should consist of certainly like this, and namely it is until all hide depression in the scope of tap, in order to enter in the zone of outer surface of yarn forming element with allowing air free.In description subsequently, also will elaborate favourable alternative.
In addition advantageously, cover component constitutes liner ring, and it hides or covered the part of the outer surface of the part of injection channel and yarn forming element at least.In favourable improvement project, cover component has inner surface for this reason, and the profile of this inner surface is equivalent to the profile of the exterior surface area of matrix basically.As a result, cover component consists of for a kind of cover plate with middle aperture, the part of matrix with extend by aperture in the middle of this after cover component carries out corresponding the connection.Cover component preferably has the side view of frustum-like shape, and this side view has the one or more ladders of possibility, and wherein relatively thin wallboard (wallboard thickness is for example less than 2mm) surrounds the cavity that the part is holding matrix.
Also very advantageously, cover component is made of plastics, and is minimum so that manufacturing cost is down to.Plastics should be constructed preferably antistaticly or conduction, in order to avoid twisting the negative influence in spinning process.In addition, cover component can constitute rotational symmetric, or has protective finish, in order to overcome wearing and tearing by the fiber that may coat in advance.
Also advantageously, cover component has the section's section that has covered tap, and this section can be brought in the position of vacating tap when packing air into to injection channel.This section is made by the material of the elasticity of flexure at this or (part), or can be used as whole in the position of having vacated tap with sealed between the position in aperture mobile.The advantage of this structural scheme is, can be when the spinning running, namely in injection channel is not also packed stage of air into, seal this aperture (namely this aperture is to consist of like this, namely it without the air back-pressure move in its closing position).Therefore, fiber that may sucking-off from the minor air cell can not arrive in the injection channel by tap, has therefore avoided its obstruction.On the contrary, if air pressure is so high in the charging process of injection channel, blow to the minor air cell from injection channel so that existing fiber or the dirt that carries have reliably, then whole cover component also can be made of stiff material.
In addition advantageously, cover component abuts on the outer surface of matrix in the scope of injection channel.Thus, avoided air-flow between matrix and the cover component in the outside of injection channel.Matrix and cover component for example can adhere to each other for this reason.
In addition advantageously, between matrix and cover component, potted component is set, for example with the form of sealing ring.Therefore, also can avoid the air-flow of not expecting between matrix and the cover component.Sealing ring is preferably placed in the annular depression of matrix and/or cover component at this, and in can be when needed same and the above-mentioned part one or two is bonded together.
Also advantageously, cover component has (interior) screw thread in order to link to each other with matrix, the opposed screw thread of this screw thread and matrix (it preferably constitutes external screw thread) acting in conjunction.In this improvement project of the present invention, cover component can constitute a kind of locking nut, and it is screwed on the matrix.After tightening, produced the injection channel of expectation by the depression that hides matrix, wherein tap should be vacated this injection channel again.
In addition advantageously, cover component and matrix link to each other in locking manner by clip connector (namely for example the protuberance of the corresponding embedding of the depression in the matrix surface and cover component) type.Except manufacturing technology was simple, the clip connector also had other advantage, and namely cover component can be removed from matrix when needed again, and was replaced by new cover component.
Also very advantageously, yarn forming element or matrix and/or cover component have at least one safety element, stop the rotation of yarn forming element under can the state in installing to yarning part by it.This safety element for example is made of protuberance at this, and it is embedded in another supporting depression that abuts in part on the part separately, antitorque supporting.Corresponding safety bolt, brake also or various groove-spring connector also can consider.In all cases, one or more in the said elements of yarn forming element should have corresponding safeties, and it can stop the separately rotation of element under the state in installing to yarning part.In other words, should guarantee by the measure of structure aspect, can not change injection channel in the position of inside, minor air cell.Guarantee by this way, have in the situation of axialy offset between the guide channel of discharge-channel and fibre guide element, injection channel extends (wherein certainly existing certain space length between guide channel and injection channel) basically in the extend longitudinally part of guide channel.
At last, be characterised in that by method of the present invention, that be used for preparing at yarning part the joint process, the end portion section of the yarn of having produced is blown into and/or sucks by discharge-channel against the spinning direction, and after from discharge-channel, discharging, caught by the air-flow that between the preparatory stage of joint process, produces, and move in the guide channel of fibre guide element, wherein the local at least outer surface along the yarn forming element of this air-flow extends in the direction of guide channel.Therefore this air-flow has been realized converging, and has realized continuing to carry by guide channel, so yarn section section can for example be caught by manipulator after through the fibre guide element, and contacts (namely the part is overlapping) with fiber band to be spinned for the joint process.After successfully feedback the yarn end, air-flow stopped again, so the yarn end imports in the yarning part with fiber band, and the yarn of new production can be pulled out by discharge-channel at last.Discharge-channel preferably loads by air-flow during the back coupling of yarn end equally, and this air-flow extends in the direction that it enters the hole, and links to each other with the air-flow that produces by injection channel in the scope that enters between hole and the guide channel.Therefore compare with the inside of discharge-channel, the flowing velocity of the inside of fibre guide element is higher, so the yarn end always is under certain stress, and this stress is assisted the back coupling of yarn end extraly.
The of the present invention favourable improvement project of more than setting forth and/or repeating in the dependent claims can both also or with arbitrarily combination realize separately, unless each is incompatible in that clear and definite dependence or each alternative are arranged in some cases.

Fig. 8 shows the yarning part that has by another embodiment of fibre guide element of the present invention.
The specific embodiment
Fig. 1 there is shown yarning part 2 by the sir jet spinning machines of prior art in the side-looking of partly cut-away.This yarning part 2 comprises fibre guide element 24, to be spinned and most fibrous material 26 that exists as the fiber band of drawing-off arrives at by this fibre guide element in the so-called minor air cell 27 of yarning part 2, finally carries out original spinning process in this minor air cell.The drafter that is arranged on fibre guide element 24 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 23 usefulness to catching, this roll is to should arrange to such an extent that directly be connected on the fibre guide element 24 as far as possible, to avoid wrong delay.
If fracture appears in yarn now, fibrous material 26 crackle occurs or yarn 5 is cut (for example because diameter fluctuation is too large) wittingly, the yarn end of the yarn 5 of then having produced must guide by discharge-channel 4 against the spinning direction, also the guide channel 22 by fibre guide element 24 guides at last, so that it and fibrous material 26 are overlapping, and again be transferred to (so-called joint) in the minor air cell 27 with fibrous material 26.
In order to allow the yarn end move by discharge-channel 4, yarn forming element 1 preferably has air duct 10, and it leads in the discharge-channel 4 with wedge angle.If air duct 10 links to each other with unshowned superpressure source now, then can produce air-flow, this air-flow begins upper part by discharge-channel 4 from air duct 10, and from it enter hole 3 by minor air cell 27, the guide channel 22 by fibre guide element 24 extends outwardly at last.
Both made this air-flow mostly be enough to make the yarn end to be moved by discharge-channel 4 in the situation, and also move by fibre guide element 24 subsequently, especially when guide channel and discharge-channel 4 are setovered from the side (shown in Fig. 1 and 2), also may cause the collision (see figure 2) of yarn end and fibre guide element 24.
In order to deal with this shortcoming, now by the present invention's suggestion, yarn forming element 1 has injection channel 6, it extends to the inside of the wallboard that surrounds discharge-channel 4 of yarn forming element 1 at least partly, and lead in the tap 8, this tap is positioned at the scope of the outer surface of yarn forming element 1 (before elaborating the present invention and favourable structural scheme thereof, illustrate in advance at this, certainly have equally corresponding spinneret 7 by Fig. 3,4,5 and 8 yarning part 2, but they for vision clearly reason do not illustrate at this; Same also possible also in many cases also advantageously, the yarn forming element 1 shown in Fig. 3,5 and 8 is provided with one or more air ducts extraly, as described in conjunction with Fig. 1 and 2.
For example Fig. 3 shows the significant advantage by injection channel 6 of the present invention now.As appreciable in the accompanying drawing from then on, it is connected to again mutually and should has on the superpressure source by injection channel 6() during the back coupling of yarn end, produced air-flow 9, the pinnacle of this air-flow from tap 8 beginnings along yarn forming element 1 extends to the guide channel 22 of fibre guide channel 22 always.If yarn end now to be feedback enters hole 3 by discharge-channel 4 processes after its route, then it arrives in the vortex of this air-flow 9, and import reliably in the aperture, below of guide channel 22 at last, and finally transmit outwardly by fibre guide element 24.
Preferably, injection channel 6 is arranged on extending axially in the part of guide channel 22, but it also can be in other position (for example in Fig. 3) be arranged on the right of discharge-channel 4.In all cases, all can produce air-flow 9 by injection channel 6, it is by fibre guide channel 22 acquisition approachs, and the yarn end also should obtain this path in preparing the joint process, has therefore realized reliable yarn back coupling.
As can be known from Fig. 4, same possible is that (also can consider in by the embodiment of Fig. 3) can flock together air duct 10 and injection channel 6 and lead in the common air feed passage 11.If this air feed passage 11 loads by superpressure during the yarn of expectation is feedback now, then at the discharge-channel 4 inner air-flows that produce, this air-flow makes yarn 5 mobile in the direction that enters hole 3, and unite at outside and the air-flow 9 of yarn forming element 1 at last, this air-flow produces by injection channel 6.Produced by this way air-flow 9 in the zone that enters between hole 3 and the fibre guide element 24, its flowing velocity is higher than the air-flow that is in the ascendance in discharge-channel 4.The yarn end can be caught securely, and conduction in fibre guide element 24 guide channels 22, and carries outwardly at last.Therefore, enter hole 3 and also can realize expecting little diameter, because restricted less air volume flow is replenished by the additional airflow 9 of injection channel 6 thus, when yarn 5 is feedback, exist this air volume flow in the inside of discharge-channel 4.
Can draw in the summary of Fig. 3 and 4 at last, injection channel 6 or its section's section 20 needn't be forcibly extended abreast with the longitudinal axis of discharge-channel 4, and this section is connected to tap 8 and normally straight extension.The layout that tilts is more favourable, so section's section 20 of the straight extension of injection channel 6 and discharge-channel 4 surround the angle between 1 ° and 10 °.
Fig. 5 shows its hollow spindle normally by yarn forming element 1(of the present invention, or be this spindle be called as the most advanced and sophisticated front part section independent, that can get loose of spinning) especially favourable embodiment.Yarn forming element 1 by front figure constitutes one, and is made of two discrete components that are connected with each other by the yarn forming element 1 of Fig. 5, i.e. matrix 12 and the cover component 13 that is attached thereto.
The significant advantage of this structure is that the manufacturing of injection channel 6 is relatively simple.It must be realized as the hole in the yarn forming element 1 of one mostly, can make by milling or similar method of surface finish by 6 of the injection channels of Fig. 5.Therefore suitablely be, in the outer surface of matrix 12, mill out the sagging place of channel form, it after placing cover component 13 towards outer closure.This cover component 13 as far as possible fully abuts on the matrix 12 at this, can only spill by injection channel 6 with the air of guaranteeing to be blown into.
In addition, as can drawing in the summary of Fig. 5 to 7, injection channel 6 preferably extends along the outer surface of matrix 12, and causes for example stair-stepping profile at this.On the side that enters hole 3 of discharge-channel 4, injection channel 6 leads in the tap 8 at last, and it is called the section's section that cover component 13 hides of not mending at the place 14 of sinking.
For matrix 12 can be linked to each other each other securely with cover component 13, the docking screw thread 16 that described part for example has screw thread 15 and matches with it, so cover component 13 can cover by matrix 12 as locking nut, and be screwed in together with it.
Last another possible connected mode that in Fig. 8, also can draw matrix 12 and cover component 13.In this scheme, realize the connection of these two parts by clip connector 19, wherein this clip connector is made of (certainly the sagging place of matrix 12 and the corresponding embedding protuberance wherein of cover component 13, should also can be arranged on the cover component 13 at sagging place, and matrix 12 arranges corresponding protuberance).Because described element preferably is not to extend round the excircle of matrix 12, so their are used with respect to the retainer that reverses of matrix 12 as cover component 13 simultaneously.If cover component 13 is not fully axisymmetric, then this point is favourable (for example, consisting of the sagging place of injection channel 6 if equally or alternatively have (together) towards the sagging place 14 of matrix 12).May be considered that also as shown in Figure 8, the end portion section 21 adjacent with tap 8 of cover component 13 constructed to such an extent that separate with the outer surface of yarn forming element 1, in order to can draw away targetedly air-flow 9.End portion section 21 also can alternatively constitute pliable and tough, and therefore as long as injection channel 6 does not load by air, then this end portion section can be sealed tap 8.
Last Fig. 8 shows, and between matrix 12 and cover component 13 seal can be set, for example with the form of sealing ring 17, to avoid the wrong air-flow of injection channel 6 outsides.In addition, matrix 12 also has the safety element 18 that form is recess, can prevent that by it matrix 12 from reversing with respect to the section's section 28 that is fixedly installed of yarning part 2.
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.
