Description
Technical field
The utility model relates generally to a kind of open end spinning apparatus, relates in particular to the spindle that open end spinning apparatus possesses and the configuration of air injection nozzle.
Background technology
In the past, known spinning machine possess utilize swirling eddy to fiber apply sth. made by twisting around and generate the open end spinning apparatus of spun yarn.This kind open end spinning apparatus possesses: spindle, produce the air injection nozzle of swirling eddy by jet airstream around above-mentioned spindle.The fiber of the above-mentioned effect that is subjected to swirling eddy by rotation around spindle to fiber apply sth. made by twisting around, generate spun yarn.
Like this, owing in open end spinning apparatus, utilizing swirling eddy that fiber twisting is formed spun yarn, so the quality of this spun yarn be subjected to a great extent swirling eddy the type of flow about.So the shape etc. that flows through the spindle of swirling eddy to formation position of the air injection nozzle that is used to produce swirling eddy etc., was around descended very big time in the past.
For example, in the disclosed spinning apparatus of TOHKEMY 2003-193337 communique, air injection nozzle (air jet hole) is set as, the air that will spray from this air injection nozzle is on the tangential direction of the arc sections in the bight, upper end that is formed at spindle (hollow guiding axis body (hollow guide shaft body)), and ejection downwards.In this look-ahead technique document, the air that sprays from air injection nozzle becomes the swirling eddy on every side that flows through hollow guiding axis body with helical form downwards.
Japanese kokai publication hei 3-241021 communique discloses the formation that the angle of inclination of air injection nozzle (nozzle) is set as the above and angle that 90 degree are following of 70 degree with respect to the direct of travel of fibre bundle.In this look-ahead technique document, put down in writing, can obtain thus can gratifying twisting count yarn.And if with reference to Fig. 2 of this look-ahead technique document, then the ejiction opening of air injection nozzle is located at the upstream side of spindle head end.
TOHKEMY 2008-297687 communique discloses following formation, that is, the outlet of air injection nozzle (air nozzle) is not towards counter-rotating chamber (suction pressure-reducing chamber) (that is, forming above-mentioned outlet in the downstream of the head end of spindle).The situation that this look-ahead technique document suppresses to eject whereby from air injection nozzle air spreads hastily.In addition, disclosed spinning machine in this look-ahead technique document by spindle is made as cylindrical (constant diameter) from its head end side the scope of specific length, thereby makes the constant cross section of swirling eddy generating chamber in the scope of afore mentioned rules length.This look-ahead technique document is given stable rotation air-flow on the whole whereby, thereby can produce swirling eddy effectively.
As TOHKEMY 2003-193337 communique, under the situation of the formation of injection air on the tangential direction of the arc sections in the bight, upper end that is formed at spindle, from the ejection air of air injection nozzle, might with the head end collision of spindle.If air and hollow guiding axis body collision like this then will be expanded hastily by the compressed air with ejection at a high speed.Thus, can't produce the situation of swirling eddy with regard to having the velocity of compressed air reduction.Consequently, counter-rotating fiber (reversal fiber) can't be wound on the core fibre (core fiber), thereby have the situation that can't generate spun yarn.
Stable from the movement that makes the counter-rotating fiber and this counter-rotating fiber is given the tension force of appropriateness viewpoint consideration preferably forms the counter-rotating fiber by the state that moderately pushes to the spindle head end.But, as Japanese kokai publication hei 3-241021 communique, the ejiction opening of nozzle is located under the situation of upstream side of head end of spindle, according to the inclination angle of nozzle, having can't be with the compressed-air actuated power that sprays from this nozzle situation of fiber to the head end pushing of spindle of will reversing.Promptly, in the formation of this look-ahead technique document, under the big situation in the inclination angle of nozzle (particularly 70 °～90 °),, therefore can't utilize this compressed air to push to the head end of spindle with the enough power fiber that will reverse because compressed air is aimed at the upstream side ground ejection of the head end of spindle.For this reason, in the formation of this look-ahead technique document, have the situation that the counter-rotating fiber forms the state that floats from the spindle head end.Fiber floats from the spindle head end if reverse like this, then just can't give enough tension force to the coiling fiber when twisting.In addition, also can produce problems such as winding takes place between the end of the counter-rotating fiber that floats.Consequently, the situation of the yarn strength reduction of the spun yarn that can generate to some extent.
In the TOHKEMY 2008-297687 communique, the outlet of air nozzle is formed at head end than spindle near the downstream.So, have the counter-rotating fiber forms the state that is exceedingly pushed to spindle by the compressed-air actuated power of spraying from this air nozzle situation, thereby hinder the rotation of counter-rotating fiber.In addition, in the formation of this look-ahead technique document, the space between nozzle block and spindle is constant.Thus, the swirling eddy that is caused by the compressed air that ejects from air nozzle flows to the downstream easily.So along with swirling eddy flows to the downstream, flow (the axial flow composition) towards the downstream of swirling eddy increases, this swirling eddy reduces flow (the rotation composition) of the rotation of counter-rotating fiber sharp on the contrary.Consequently, the situation that the rotary speed reduction of counter-rotating fiber occurs.
The utility model content
The purpose of this utility model is, provides a kind of movement that can make the coiling fiber stable and improve the open end spinning apparatus of the yarn strength of spun yarn.
According to first viewpoint of the present utility model, utilize swirling eddy to make the fiber rotation of fibre bundle and the open end spinning apparatus of making spun yarn possesses suction pressure-reducing chamber portion, rotating room portion, spindle.Be formed with the suction pressure-reducing chamber in above-mentioned suction pressure-reducing chamber portion.Be formed with than the longer rotating room of girth, above-mentioned suction pressure-reducing chamber in above-mentioned rotating room portion.Be formed with the air injection nozzle that in above-mentioned rotating room, produces above-mentioned swirling eddy from spraying compressed air more than 1 in above-mentioned rotating room portion to the jet hole of above-mentioned rotating room inner opening.Be formed with fiber in the inside of above-mentioned spindle and pass through the road.Above-mentioned spindle is configured to, and above-mentioned fiber is positioned at above-mentioned suction pressure-reducing chamber by the cephalic par of the entrance side on road.The said nozzle mouth is set in the conveyance direction downstream side than the close above-mentioned fibre bundle of cephalic par of above-mentioned spindle.
Like this, by jet hole being formed at rotating room's side, the head end of spindle is configured to be positioned at the suction pressure-reducing chamber, just can prevents that the compressed air that sprays from expanding from jet hole near the head end of spindle.Consequently, the fiber that can prevent to reverse floats at the spindle head end.That is, can utilize above-mentioned compressed air, the fiber that will reverse stably pushes to the spindle head end.In addition, the girth by making the suction pressure-reducing chamber is than all length of rotating room, and dilated compressed air just is difficult to from the rotating room to suction pressure-reducing chamber side inflow.Like this, the rotation composition of the swirling eddy in the suction pressure-reducing chamber will diminish, and the pressure-reducing chamber is aspirated in the domination of flow air stream reposefully towards the downstream.So it is smooth and easy that the counter-rotating of the fiber in the rotating room will become, can stably obtain to be wound on the tension force of the appropriateness of the fiber on the core fibre.Consequently, the yarn strength of the spun yarn that is generated improves.In addition, because the counter-rotating fiber is difficult to float from the spindle surface,, also can realize stable spinning even therefore under the situation of the rotary speed that has increased fiber.Thus, just can tackle in the past spinning apparatus of utilization (spinning speed be 250m/min about 400m/min) 500m/min that can't realize or the high-speed spinning of 600m/min.
In the said flow spinning apparatus, in the section with through the plane cutting of the axis of above-mentioned spindle the time, form the section profile of the part of above-mentioned at least suction pressure-reducing chamber side in the interior sidewall surface of above-mentioned rotating room portion of above-mentioned rotating room, formed with curve-like in fact.Like this, owing in the rotating room, can therefore can prevent to get muddled, this air flow is flowed swimmingly not with the partly formation of corner angle in the wall of suction pressure-reducing chamber side in the rotation indoor air stream.Consequently, the fiber that can prevent to reel is wound on the core fibre brokenly, or twines between the free end of coiling fiber, thereby can make the stay in grade of the yarn that is generated.
In the said flow spinning apparatus, at least a portion of the opening profile of said nozzle mouth, the central above-mentioned section profile of interior sidewall surface that is formed in the above-mentioned rotating room portion that forms above-mentioned rotating room is in the above-mentioned curvilinear part.Like this, being formed at section profile by at least a portion with jet hole is in the curvilinear wall, just can prolong the oval girth of the opening profile of this jet hole.Like this, just can spray compressed air, can in the scope of broadness, make swirling eddy impact fiber, therefore can fiber be rotated effectively from jet hole broadening ground in the rotating room.In addition, under the situation of the wall band corner angle of rotating room as open end spinning apparatus in the past, if will then offset slightly across this partly formation jet hole with corner angle as long as form the position, the shape of jet hole will change significantly, and flowing of the air in the rotating room also can change.So, in the wall of band corner angle, forming under the situation of jet hole, the quality of the yarn that is generated just is subjected to the influence of the machining accuracy of jet hole easily.But, be under the situation in the curvilinear wall as described above jet hole being formed at section profile, slightly offset even form the position of this jet hole, the outlet shape of injection nozzle does not have any variation yet.That is, constitute open end spinning apparatus as described above,, can guarantee the quality of the yarn that generated then regardless of the machining accuracy of jet hole.
In the said flow spinning apparatus, when looking up with the central axis quadrature of above-mentioned spindle and with the side of the length direction quadrature of above-mentioned air injection nozzle, the length direction of above-mentioned air injection nozzle tilts with respect to the central axis of above-mentioned spindle angle above with 70 degree and that 80 degree are following.Like this, in the rotating room, act on the speed of direction of rotation of swirling eddy of fiber and fibre transportation direction speed be equilibrated at high-speed spinning the time will become good especially.That is, can utilize the compressed air that from the air injection nozzle that is formed as described above, sprays, in the suction streams that produces the downstream drawing-off of fiber orientation fibre transportation direction, make this fiber with enough speed rotations.Consequently, can improve the intensity of the spun yarn that is generated.In addition, obtain keeping owing to act on branchs that be rotated into of the air of fiber in the rotating room, therefore the staple fibre of suspension is inverted fiber and catches in turn and reel down, thereby can reduce fiber loss.
In the said flow spinning apparatus, the flow path cross sectional area of the end of downstream side of above-mentioned rotating room preferably is made into, less than the flow path cross sectional area of the position that is formed with the said nozzle mouth of this rotating room.Like this, just can this swirling eddy be remained high speed at swirling eddy by during before in the rotating room, discharging.That is owing to can in the rotating room, make fibre high-speed ground rotation, even so under the situation of high-speed spinning, also can improve the yarn strength of the spun yarn that is generated.

Nozzle block (suction pressure-reducing chamber portion, rotating room portion) 34 is configured in than the position of fiber guiding section 23 near the downstream.Fig. 4 is the detailed profile of expression nozzle block 34.Fig. 4 is the profilograph with the nozzle block 34 of the plane identical with Fig. 3 (guiding the plane of the axis of axis body 20 through hollow) cutting.As shown in Figure 4, in this nozzle block 34, be formed with open-work 70.Open-work 70 is made into, and the section shape with central axis 90 plane orthogonal (with the fibre transportation direction plane orthogonal) cutting of hollow guiding axis body 20 time is a circle.
As shown in Figure 3, hollow guiding axis body 20 possesses: by the cylinder (columnar body) 56 of axis body retaining member 59 maintenances.At an end of cylinder 56, be formed with the tapered portion 24 of taper.At the head end of tapered portion 24, be formed with ingate 28.At the axle center part of cylinder 56, be formed with the fiber that is communicated with ingate 28 and pass through road 29.And fiber becomes outlet opening (omitting diagram) by the end of downstream side on road 29.Through fibre bundle 8 or the spun yarn 10 of fiber by road 29, the yarn feeding device 11 in the downstream by being disposed at open end spinning apparatus 9 is sent to the outside of open end spinning apparatus 9 from above-mentioned outlet opening.
The tapered portion 24 of hollow guiding axis body 20 is seen by the opposite side from fiber guiding section 23 from nozzle block 34, inserts the inside that is formed at the open-work 70 in this nozzle block 34 when making the axis unanimity.For air flow can be passed through, between the interior sidewall surface (wall of open-work 70) of the outer peripheral face of the tapered portion 24 of hollow guiding axis body 20 and nozzle block 34, separate the interval of regulation.
In nozzle block 34, be formed with suction pressure-reducing chamber 71, rotating room 72, taper chamber 73 in turn from the direct of travel upstream side of fibre bundle 8.More strictly speaking, utilize the outer peripheral face of the tapered portion 24 of hollow guiding axis body 20, the interior sidewall surface (wall of open-work 70) of nozzle block 34, form the rotating room 72 of approximate columned suction pressure-reducing chamber 71, approximate circle tubular, the taper chamber 73 of approximate awl tubular.And, be made as the approximate circle column though will aspirate pressure-reducing chamber 71, yet the cephalic par (fiber is by the cephalic par of the ingate 28 on road 29) of hollow guiding axis body 20 is inserted a little from the downstream in suction pressure-reducing chamber 71 to the inside in this suction pressure-reducing chamber 71 in fact as shown in Figure 3.
As shown in Figure 3, suction pressure-reducing chamber 71 is interconnected with the fiber entrance hole 21 of fiber guiding section 23.Rotating room 72 is interconnected with suction pressure-reducing chamber 71.Taper chamber 73 is interconnected with rotating room 72.
Around nozzle block 34, be formed with supply gas and store chamber 61.At spray nozzle part case 53 places, be connected with and omit the compressed air supply pipe 65 that illustrated compressed air source is connected.Like this, just can store chamber 61 supply compressed air to above-mentioned supply gas from above-mentioned compressed air source.
In nozzle block 34, be formed with rotating room 72 is stored the air injection nozzle more than 1 27 that chamber 61 is communicated with supply gas.In the present embodiment, though be formed with 4 air injection nozzles 27, the number of formed air injection nozzle 27 is not limited thereto.Air injection nozzle 27 is constituted with the elongated circular hole that is arranged in the nozzle block 34.Store the compressed air that chamber 61 is supplied to supply gas, in rotating room 72, spray via air injection nozzle 27.Like this, in rotating room 72, will produce around hollow and guide the axis of axis body 20 along the mobile rotatably swirling eddy of a direction.
In order in rotating room 72, to produce aforesaid swirling eddy, the length direction of air injection nozzle 27, when overlooking towards the rotating room 72 roughly tangential direction.And the length direction of air injection nozzle 27 is depicted as being in together in the plane identical with the central axis of rotating room 72 among Fig. 3, however this way of (conceptually) performance briefly only for figure is understood easily.In fact air injection nozzle 27 is formed as described above in the rotating room 72 tangential direction.So the profile of representing air injection nozzle 27 more accurately as shown in Figure 4.
As shown in Figures 3 and 4, air injection nozzle 27 is formed its length direction on slightly inclined ground, downstream.The compressed air that sprays from air injection nozzle 27 is flowed towards the downstream.
In above formation, the compressed air that sprays from air injection nozzle 27 in the rotation, flows towards the direct of travel downstream of fibre bundle 8 in rotating room 72.That is, in rotating room 72, can produce the spiral helicine swirling eddy that flows towards the downstream.
Being formed with air in spray nozzle part case 53 discharges with space 55.Air is discharged with space 55 and taper chamber 73 and is interconnected.Discharge with 55 places, space at air, be connected with the illustrated negative pressure source of omission (aspirating mechanism) that is disposed in the above-mentioned gettering container 4 through pipe arrangement 60.
Below, describe at the appearance when fiber entrance hole 21 imports fibre bundle 8 in the open end spinning apparatus 9 that constitutes as described above.
At first, under the state that in open end spinning apparatus 9, does not import fibre bundle 8 (state of Fig. 3), store chamber 61 supply compressed air to supply gas from omitting illustrated compressed air source.Store the compressed air that chamber 61 is supplied to supply gas, in rotating room 72, spray via air injection nozzle 27.Thus, the swirling eddy that produces in rotating room 72 after flowing through to side in this rotating room 72 downstream with helical form, flows into taper chamber 73.Swirling eddy further flows to the downstream when weakening its flow velocity, finally discharge with space (air discharge space) 55 from air and discharge.
In rotating room 72, produce as described above towards the flowing of the air in downstream, in the adjacent suction pressure-reducing chamber 71 of the upstream side of this rotating room 72, just be depressurized, in fiber entrance hole 21, produce suction air flow.Suction air flow flows into suction pressure-reducing chamber 71 from fiber entrance hole 21.Thereafter, the part of suction air flow flows into fiber by flowing to the downstream in the road 29.Remaining suction air flow flows into rotating room 72 and converges with swirling eddy.
If from drafting system 7 fibre bundle 8 is sent to open end spinning apparatus 9 sides under this state, then this fibre bundle 8 is just aspirated from fiber entrance hole 21, guiding in suction pressure-reducing chamber 71.Direct into fibre bundles 8 in the suction pressure-reducing chamber 71 taking advantage of flows into the mobile quilt of fiber by the suction air flow in the road 29 through this fiber by road 29 downstream side guide, be sent to the outside of open end spinning apparatus 9 from omitting illustrated outlet opening.
The fibre bundle of sending from the above-mentioned outlet opening of open end spinning apparatus 98 or the end of spun yarn 10 are caught by the suction pipe 44 that joint chassis 3 is possessed, at the yarn end connector of splicer 43 places and package 45 sides.Like this, fibre bundle 8 or spun yarn 10 just become, and are extended down to the continuous state of yarn feeding device 11 by road 29 through fiber entrance hole 21, suction pressure-reducing chamber 71 and fiber from preliminary roller 18.Under this state, give carrying capacity by utilizing yarn feeding device 11 towards the downstream, give tension force ground to spun yarn 10 and from open end spinning apparatus 9, in rapid succession spun yarn 10 is pulled out.
Below, with reference to Fig. 5 come in the open end spinning apparatus 9 of present embodiment to fibre bundle 8 apply sth. made by twisting around and the appearance that generates spun yarn 10 describes.And, conceptually represent the flowing of air in the open end spinning apparatus 9 with the arrow of thick line among Fig. 5.
Import the end of downstream side of each fiber in suction pressure-reducing chamber 71, when constantly being twisted, twist with the fingers into core fibre 8a.But each fiber is not to be that its whole sth. made by twisting is gone into core fibre 8a, and upstream-side-end becomes free end.
In the time of in the above-mentioned free end (upstream-side-end) of each fiber enters suction pressure-reducing chamber 71, this free end separates with core fibre 8a and is opened fibre, and is utilized from the suction air flow of 71 inflow rotating rooms 72, suction pressure-reducing chamber and rushes at rotating room's 72 sides (downstream).Like this, rush at the downstream by upstream-side-end with fiber, this upstream-side-end towards will " reversing ".The fiber of this state is called counter-rotating fiber (reversal fiber) 8b.And, originally be core fibre 8a fiber also at its upstream side end one enter in the suction pressure-reducing chamber 71, promptly become counter-rotating fiber 8b.
The free end of counter-rotating fiber 8b is imported into rotating room 72, is subjected to towards the downstream with the influence of the mobile swirling eddy of helical form.Like this, as shown in Figure 5, counter-rotating fiber 8b just in the surface of the tapered portion 24 of guiding axis body 20 along hollow, guides the rotation on every side of the tapered portion 24 of axis body 20 in this hollow.So the free end of counter-rotating fiber 8b will circle round around through the core fibre 8a of fiber by 29 inside, road.Like this, counter-rotating fiber 8b with regard to be wound in turn core fibre 8a around and become the coiling fiber.
At this moment, counter-rotating fiber 8b flows to the surface pushing of the power in downstream to the tapered portion 24 of hollow guiding axis body 20 by the intention of swirling eddy.So, the free end situation out of control of the fiber 8b that just can prevent to reverse, counter-rotating fiber 8b can be stably rotation around the tapered portion 24 of hollow guiding axis body 20.
Like this, will generate the real spun yarn 10 of twisting with the fingers shape.Spun yarn 10 advances in by road 29 at fiber, is sent to yarn feeding device 11 from above-mentioned outlet opening (omitting diagram).
By via yarn feeding device shown in Figure 1 11 coiling spun yarn 10 on coiler device 12, just can finally form package 45.And, above-mentioned fiber open fibre and when twisting waited the fiber of twisting with the fingers spun yarn 10 because of fracture, taking advantage of flowing of air flow 72 to be sent to air through taper chambers 73 and to discharge with space 55 from the rotating room, utilize the suction of negative pressure source, via pipe arrangement 60 discharges.
Below, the formation of the nozzle block 34 of the open end spinning apparatus 9 of present embodiment is elaborated.
At first, the shape that the rotating room that forms rotating room 72 is formed face 82 describes.
As shown in Figure 4, in the interior sidewall surface (wall of open-work 70) of nozzle block 34, the part that forms suction pressure-reducing chamber 71 is made as the suction pressure-reducing chamber forms face 81, the part that forms rotating room 72 is made as the rotating room forms face 82.The suction pressure-reducing chamber forms face 81 in suction pressure-reducing chamber 71.The rotating room forms face 82 in rotating room 72.
Profile when Fig. 4 represents with the nozzle block 34 of the plane cutting present embodiment of the central axis of guiding axis body 20 through hollow.In this profile, the part that the rotating room forms the upstream side (suction pressure-reducing chamber 71 sides) of face 82 is that its section profile is curvilinear curve part 82a, and the part that the rotating room forms the downstream of face 82 is that its section profile is the line part 82b of linearity.
In the open end spinning apparatus 9 of present embodiment, the suction pressure-reducing chamber forms the radius R 1 of face 81, is made into littler than the radius R 2 (radius of the line part 82b that says so exactly) of rotating room's formation face 82.In other words, the girth of rotating room 72 is longer than the girth in suction pressure-reducing chamber 71.Like this, short by the radius ratio rotating room 72 that makes suction pressure-reducing chamber 71, even under the situation that the compressed air of ejection expands in the left-hand tools chamber 72, also can make this compressed air be difficult to flow to suction pressure-reducing chamber 71 sides.Thus, owing in suction pressure-reducing chamber 71, air flow is flowed swimmingly towards the downstream, therefore can in suction pressure-reducing chamber 71, fiber be reversed swimmingly.
As shown in Figure 4, the end of downstream side of suction pressure-reducing chamber formation face 81 is connected by curve part 82a with the upstream-side-end that the rotating room forms the line part 82b of face 82.In the profile (figure of Fig. 4) when the plane cutting of the central axis of guiding axis body 20 with process hollow, curve part 82a is connected smoothly with the section profile of line part 82b.Like this, the section profile of the upstream side (fiber guiding section 23 sides) by the rotating room being formed face 82 is made as curve-like, just can constitute in rotating room 72 not the part with corner angle.
On the other hand, for example in TOHKEMY 2003-193337 communique, in rotating room (the first circular cone shape spatial portion and the second circular cone shape spatial portion), has the part (coupling part of the first circular cone shape spatial portion and the second circular cone shape spatial portion) of band corner angle.When in the rotating room, having the part of band corner angle like this, will in this rotating room, produce the disorder of air flow, unsettled situation thereby the movement that has a fiber that reverses becomes.
But, in the present embodiment and since as described above in rotating room 72 not with the partly formation of corner angle, therefore can reduce the disorder of the air flow in the rotating room 72.So, can make the movement of the counter-rotating fiber in the rotating room 72 stable.Consequently, the fiber 8b that can prevent to reverse floats from the surface of the tapered portion 24 of hollow guidance axis body 20, thereby stably generates high-quality spun yarn 10.
In the present embodiment, the section profile of curve part 82a forms circular-arc specifically.Circular-arc by like this section profile of rotating room 72 being made as, just can reduce the disorder of the air flow in the rotating room 72 especially well.By reducing the disorder of the air flow in the rotating room 72, just can make the compressed air of ejection in rotating room 72 be difficult in this rotating room 72, expand.
Under spinning speed as 500m/min or 600m/min is at a high speed situation, make the counter-rotating fiber with respect to core fibre reliably and at short notice (at high speed) rotation be particular importance.But in case form high-speed spinning, the fiber 8b that then will reverse introduces fiber and will shorten by the time before the road 29, so the slight disorder of the air flow in the rotating room 72 will cause very big influence to the rotating speed of counter-rotating fiber 8b.By as present embodiment, with circular-arc formation, just can make the air flows in the rotating room 72 stable the section profile of the curve part 82a of rotating room 72.Thus, even under the situation of high-speed spinning, also can stably generate high-quality spun yarn 10.
Below, the air injection nozzle 27 of present embodiment is described.
As previously mentioned, air injection nozzle 27 is by 72 roughly tangential direction ground forms towards the rotating room with its length direction.So air injection nozzle 27 forms the opening profile of the part (jet hole 27a) of face 82 split sheds in the rotating room, just become approximate ellipsoidal as shown in Figure 4.In the present embodiment, the girth of the opening profile of this jet hole 27a is called oval girth.
In the open end spinning apparatus 9 of present embodiment, as shown in Figure 4, the jet hole 27a of air injection nozzle 27 is formed among the curve part 82a of rotating room's formation face 82.Like this, compare oval girth that can extended jet nozzle mouth 27a with the situation that for example in line part 82b, forms jet hole 27a.So, air injection nozzle 27 just can according to make compressed air downstream the mode of side broadening spray compressed air.Like this, owing to can make swirling eddy in the scope of broadness, act on fiber, therefore can make the fiber rotation effectively with powerful power.In addition and since can be like this with compressed air towards the ejection of broadening ground, downstream, even therefore under the situation that this compressed air expands in rotating room 72, this compressed air also is difficult to towards upstream side (aspirating pressure-reducing chamber 71 sides) diffluence.Like this, side is mobile more swimmingly downstream just can to make suction air flow, further reduces the disorder of the air flow in the rotating room 72.
For example in TOHKEMY 2003-193337 communique, the jet hole of air jet hole is formed part (coupling part of the cylindric spatial portion and the first circular cone shape spatial portion) across the band corner angle.Thus, will there be the problem that the opening shape of jet hole then will change significantly as long as the formation position of jet hole slightly offsets.So the formation of TOHKEMY 2003-193337 communique has the shortcoming that yarn quality is subject to processing the influence of precision easily.But, in the present embodiment, the opening profile of jet hole 27a all is formed at the rotating room forms among the curve part 82a of face 82.That is, in the present embodiment, jet hole 27a is formed on not can be across the position of the part of wall band corner angle.According to the formation of present embodiment, even the position that jet hole 27a is formed slightly offsets, the shape of the opening profile of this jet hole 27a does not have any change yet.Consequently, the quality of spun yarn 10 is guaranteed on the machining accuracy ground that can be independent of air injection nozzle 27.
As shown in Figures 3 and 4, the head end of hollow guiding axis body 20 is inserted in the suction pressure-reducing chamber 71 slightly.In other words, the head end of hollow guiding axis body 20 is positioned at the upstream side that the suction pressure-reducing chamber forms the end of downstream side of face 81.The jet hole 27a of air injection nozzle 27 is formed on the rotating room and forms in the face 82.That is, jet hole 27a is formed on the downstream of the head end of hollow guiding axis body 20.Like this, just can prevent the head end collision of the compressed air that from jet hole 27a, sprays and hollow guiding axis body 20.So, expand at the head end of hollow guiding axis body 20 owing to can prevent to spray air, therefore can in rotating room 72, produce swirling eddy well.
Below, the angle of inclination of air injection nozzle 27 is described.As previously mentioned, Fig. 4 is with the profile through the plane cutting of the axis of hollow guiding axis body 20.The length direction of the air injection nozzle 271 on the right side among this plane and the figure is parallel.So Fig. 4 can be described as the figure when looking up with the central axis quadrature of hollow guiding axis body 20 and with the side of the length direction quadrature of air injection nozzle 271.Among Fig. 4, the central axis 90 of hollow being guided axis body 20 is made as tilt angle alpha with the angle of the length direction of air injection nozzle 271.
In (angle of air injection nozzle 27 precipitous situation under) under the little situation of tilt angle alpha, the ejection air will flow to the downstream surgingly.So, though can in fiber guide hole 21, produce powerful suction air flow, mobile the dying down of in rotating room 72, rotating.Consequently, counter-rotating fiber 8b can't be wound on fully core fibre 8a around, thereby have the situation that yarn strength reduces.Do not increased owing to twist with the fingers the staple fibre of core fibre, therefore the problem that fiber loss increases also can take place.On the other hand, in (angle of air injection nozzle 27 mild situation under) under the big situation of tilt angle alpha, though can utilize the ejection air in rotating room 72, to produce the swirling eddy that rotates surgingly, die down towards the mobile of downstream.Consequently, can't produce enough suction air flow at fiber entrance hole 21, thereby have the situation that to aspirate fibre bundle 8.
The present application people confirms, in the open end spinning apparatus 9 of present embodiment, if be made as more than 70 ° the angle of inclination and the scope below 80 °, then the swirling eddy rotation flow with towards the downstream flow be equilibrated in the high-speed spinning good.That is,, just can carry out the suction of fibre bundle 8 at fiber entrance hole 21 places and the rotation of the counter-rotating fiber 8b in the rotating room 72 rightly, generate high-quality spun yarn 10 by tilt angle alpha being made as in the above-mentioned scope.So, in the open end spinning apparatus 9 of present embodiment, tilt angle alpha is made as the scope below 80 ° more than 70 °.And, though in the drawings, only 1 air injection nozzle 271 is expressed tilt angle alpha, all formed yet in nozzle block 34, dispose a plurality of air injection nozzle 27 with identical angle of inclination.
Below, the flow path area of rotating room 72 is described.And so-called flow path area is meant the sectional area of the rotating room 72 with the cutting of the throughput direction plane orthogonal of fiber the time.
In the present embodiment, constitute the periphery wall of tapered portion 24 of hollow guiding axis body 20 of internal perisporium of rotating room 72 by to make towards the taper of downstream broadening.Like this, the flow path area of rotating room 72 is just along with from the formation position of jet hole 27a downstream before the side and then diminish.So, comparing with the flow path area of the position that is formed with jet hole 27a, flow path area one side of the end of downstream side of rotating room 72 diminishes.
Because the flow path area with rotating room 72 constitutes according to the mode of dwindling slightly in the downstream like this, therefore just can prevent from rotating room 72, just do not going out under the state of rotation fully as yet to taper chamber 73 effluents from the ejection air of jet hole 27a.Like this, just can in rotating room 72 before swirling eddies are discharged in taper chamber 73 during, the flow velocity of this swirling eddy is remained high speed.
As above shown in the explanation, the open end spinning apparatus 9 of present embodiment is to utilize swirling eddy to make the fiber of fibre bundle 8 rotate the open end spinning apparatus of making spun yarn 10, possesses: nozzle block 34, hollow guiding axis body 20.In nozzle block 34, be formed with suction pressure-reducing chamber 71 and the rotating room 72 longer than these suction pressure-reducing chamber 71 girths.In nozzle block 34, be formed with more than 1 from spraying compressed air to the jet hole 27a of rotating room's 72 inner openings rotating room 72 in the air injection nozzle 27 of generation swirling eddy.In the inside of hollow guiding axis body 20, be formed with fiber by road 29.Hollow guiding axis body 20 is configured to, and fiber is positioned at suction pressure-reducing chamber 71 by the cephalic par of ingate 28 sides on road 29.Jet hole 27a is set in the conveyance direction downstream side of more leaning on above-mentioned fibre bundle 8 than the cephalic par of hollow guiding axis body 20.
Like this, by according to jet hole 27a being formed at rotating room's 72 sides, the mode that the head end that makes hollow guide axis body 20 is positioned at suction pressure-reducing chamber 71 disposes, and just can prevent that the compressed air that sprays from jet hole 27a from expanding near the head end of hollow guiding axis body 20.Consequently, the fiber 8b that can prevent to reverse floats at the head end of hollow guiding axis body 20.That is, can utilize above-mentioned compressed air, counter-rotating fiber 8b is stably pushed to the head end of hollow guiding axis body 20.In addition, the girth by making suction pressure-reducing chamber 71 is than all length of rotating room 72, and dilated compressed air just is difficult to from the rotating room 72 to suction pressure-reducing chamber 71 side inflows.Like this, the rotation composition of the swirling eddy in the suction pressure-reducing chamber 71 will diminish, downstream side flow air stream domination suction pressure-reducing chamber 71 reposefully.So the counter-rotating of the fiber in the rotating room 72 will become smooth and easy, can stably obtain to be wound on the tension force of the appropriateness of the fiber on the core fibre 8a.The yarn strength of the spun yarn 10 that consequently, is generated improves.In addition, because counter-rotating fiber 8b is difficult to float from the surface of hollow guidance axis body 20, therefore, can tackle the 500m/min that in the past can't realize or the high-speed spinning of 600m/min even under the situation of the rotary speed that has increased fiber, also can realize stable spinning.
In the open end spinning apparatus 9 of present embodiment, in the section when the plane cutting of the axis of guiding axis body 20 with process hollow, the part of suction pressure-reducing chamber 71 sides is used as section profile and is essentially curvilinear curve part 82a formation in rotating room's formation face 82.Like this, in rotating room 72, just can constitute in the wall of suction pressure-reducing chamber 71 sides not part with corner angle.So, can prevent that air flow gets muddled in rotating room 72, this air flow is flowed swimmingly.Thus, the fiber that just can prevent to reel is wound on the core fibre brokenly, or twines between the free end of coiling fiber.Consequently, can make the stay in grade of the spun yarn 10 that is generated.
In the open end spinning apparatus 9 of present embodiment, among whole curve part 82a that are formed in rotating room's formation face 82 of the opening profile of jet hole 27a.Like this, by jet hole 27a is formed among the curve part 82a, just can prolong the oval girth of the opening profile of this jet hole 27a.Like this, just can spray compressed air, can in the scope of broadness, make swirling eddy impact fiber from jet hole 27a broadening ground in rotating room 72.Consequently, can fiber be rotated effectively.In addition, be formed with in curve part 82a under the situation of jet hole 27a as described above, slightly offsetting even form the position of this jet hole 27a, the outlet shape of air injection nozzle 27 does not have any change yet.That is, constitute open end spinning apparatus 9 as described above,, can guarantee the quality of the spun yarn 10 that generated regardless of the machining accuracy of air injection nozzle 27.
In the open end spinning apparatus 9 of present embodiment, when looking up with the central axis quadrature of hollow guiding axis body 20 and with the side of the length direction quadrature of air injection nozzle 27, the length direction of above-mentioned air injection nozzle 27 tilts with respect to the central axis of hollow guiding axis body 20 angle above with 70 degree and that 80 degree are following.Like this, in rotating room 72, act on the speed of direction of rotation of swirling eddy of fiber and fibre transportation direction speed be equilibrated at high-speed spinning the time will become good especially.That is, can utilize the compressed air that from the air injection nozzle 27 that is formed as described above, sprays, in the suction streams that produces the downstream drawing-off of fiber orientation fibre transportation direction, make this fiber with enough speed rotations.Consequently, can improve the intensity of the spun yarn 10 that is generated.In addition, obtain keeping owing to act on branchs that be rotated into of the air of fiber in rotating room 72, therefore the staple fibre of suspension is inverted fiber and catches in turn and reel down, thereby can reduce fiber loss.
In the open end spinning apparatus 9 of present embodiment, the flow path cross sectional area of the end of downstream side of rotating room 72 is made into, less than the flow path cross sectional area of the position that is formed with said nozzle mouth 27a of this rotating room 72.Like this, just can be before in rotating room 72, discharging swirling eddy during, this swirling eddy is remained high speed.That is owing to can in rotating room 72, make fibre high-speed ground rotation, even so under the situation of high-speed spinning, also can improve the yarn strength of the spun yarn 10 that is generated.
The spinning frame 1 of present embodiment possesses: above-mentioned open end spinning apparatus 9 and the spun yarn 10 that will utilize this open end spinning apparatus 9 to make are wound into the coiler device 12 of package 45.Like this, even, therefore compare and at a high speed and to form high-quality package 45 effectively with spinning machine in the past owing under the situation of high-speed spinning, also can generate the spun yarn 10 that has improved yarn strength.

Though the shape in suction pressure-reducing chamber 71 adopts the approximate circle column, yet is not limited thereto.Portion produces swirling eddy owing to not necessarily need in the pressure-reducing chamber 71 within it in suction, and therefore the section shape when cut with fibre transportation direction plane orthogonal also can not be a circle.But, because in this case, also to make air flow can 72 inflows not aspirate pressure-reducing chambers 71 from the rotating room, therefore preferably make the periphery length of the outer perimeter in suction pressure-reducing chamber 71 than rotating room 72.
The section profile that cause on the plane by guide the axis of axis body 20 through hollow of the curve part 82a of rotating room's formation face 82 can not be circular-arc also, as long as section profile is level and smooth curve, no matter is which kind of shape can then.In brief, as long as 72 fiber guiding section 23 sides are not with the part of corner angle in the rotating room.But, as described above the section profile of curve part 82a is made as circular-arcly, just can suppress the disorder of the air flow in the rotating room 72 especially well.
It also can be that its entire profile profile is a curve-like that the rotating room forms face 82.That is, also can omit line part 82b.
And, can regard as in fact under the situation of curve at the section profile of curve part 82a, this section profile also can be made of little broken line.For example, as long as the section profile of curve part 82a then can substantially be regarded curve as by constituting with obtuse angle warpage broken line repeatedly.
Be not as above-mentioned embodiment, in rotating room's formation face 82, to have curve part 82a, in rotating room 72, can have the part of band corner angle yet.For example, also can omit curve part 82a, only constitute the rotating room and form face 82 with line part 82b.
Though in the above-described embodiment, adopt whole formations that are formed among the curve part 82a, yet be not limited to this formation the opening profile of the jet hole 27a of air injection nozzle 27.For example, also can be only the part of the opening profile of jet hole 27a be formed among the curve part 82a, a remaining part is formed among the line part 82b.In addition, also the whole of opening profile of jet hole 27a can be formed among the line part 82b.But, if at least a portion of the opening profile of jet hole 27a is formed among the curve part 82a, then can be from jet hole 27a in rotating room 72 broadening ground spray compressed air, therefore preferred.
Though in the above-described embodiment, adopted nozzle block 34 to have the formation of suction pressure-reducing chamber portion and rotating room portion concurrently, yet also suction pressure-reducing chamber portion and rotating room portion can be made as discrete member.
Though in the above-described embodiment, air is discharged and is formed in the spray nozzle part case 53 with space 55.But air is discharged and also can be formed in the axis body retaining member 59 with space 55.Air is discharged also can be by forming spray nozzle part case 53 and 59 combinations of axis body retaining member with space 55.
Though in the above-described embodiment, fibre bundle 8 (or spun yarn 10) is illustrated by the spinning frame 1 of the type of being carried from the top down, yet is not limited thereto.It for example also can be the spinning machine of type from bottom to top.That is, also can be disposed at the loom bottom, coiler device is disposed in the spinning machine on loom top, possess the open end spinning apparatus of above-mentioned embodiment at the bar tube that will take in fibre bundle.
Spinning frame 1 also can adopt between yarn feeding device 11 and coiler device 12 formation that yarn stores device is set.So-called yarn stores device, if describe simply, then is the device that constitutes as follows, that is, by store the spun yarn 10 of temporarily reeling of roller on every side at the yarn that rotates, store on the roller and a certain amount of spun yarn 10 can be stored at this yarn.It is as follows that yarn stores the function of device.That is, coiler device 12 is carrying out the process of the joint action spun yarn 10 of can't reeling when medium at joint chassis 3.In this case, when sending spun yarn 10 in rapid succession from open end spinning apparatus 9, the spun yarn 10 of not reeled will relax.So, establish above-mentioned yarn and store device by folder between coiler device 12 and yarn feeding device 11, coiler device 12 can't reel yarn during spun yarn 10 stored at yarn store on the roller, just can prevent the situation that spun yarn 10 relaxes.
And above-mentioned yarn stores device to be possessed and spun yarn 10 is reeled and the yarn of rotation stores roller.Above-mentioned yarn stores device and stores roller rotation by making yarn, just can be wound on this yarn store on the roller spun yarn 10 downstream side send.That is, yarn stores device and possesses the spun yarn 10 side function of carrying downstream.So, possessed the spinning frame 1 that yarn stores device as described above and also can omit yarn feeding device 11, will utilize yarn to store device side conveyance downstream from the spun yarn 10 of open end spinning apparatus 9.
