Description
Technical field
The present invention relates generally to a kind of open end spinning apparatus, relates in particular in open end spinning apparatus the shape in the space producing swirling eddy.
Background technology
In the past, known spinning machine possesses and utilizes swirling eddy (whirling airflow) apply to twist around to fiber and generate the open end spinning apparatus of spun yarn.
This spinning machine is such as disclosed Japanese Unexamined Patent Publication 2003-1933337 publication.Be somebody's turn to do the Ministry of Textile Industry that spinning apparatus possesses disclosed in first technology, possess the nozzle block being formed with jet-impingement hole.
Fig. 7 be represent that this records in first technology nozzle block near the schematic cross sectional view of formation.As shown in Figure 7, in nozzle block 100 disclosed in first technology, multiple jet-impingement hole 105, open-work (passage hole) 101 is formed with at this.Above-mentioned open-work 101 is made up of cylindrical space portion (columnar space section) 102, the first circular cone shape spatial portion (first circular truncated cone shaped space section) 103 be connected with cylindrical space portion 102, the second circular cone shape spatial portion 104 of being connected with the first circular cone shape spatial portion 103.Cylindrical space portion 102 produces negative pressure therein and in Conductivity of Fiber hand-hole 106, produces the space that suction streams comes for vacuum fibers.In the following description, cylindrical space portion 102 is called suction pressure-reducing chamber.Second circular cone shape spatial portion 104 is the spaces for making reversion fiber rotate, and is called rotating room (whirling chamber) in the following description.
In first technical literature, following content is recorded above-mentioned, namely, by the effect of the ejection air from air jet hole, near the Conductivity of Fiber hand-hole of needle stand, produce suction air flow (suction airflow), fibre bundle can be sucked Conductivity of Fiber hand-hole.By making this suction air flow flow swimmingly, just can vacuum fibers bundle swimmingly.Conceptually represent the flowing of this suction air flow with the arrow of thick line in Fig. 7.
But, if the swirling eddy produced in the rotating room 104 of Fig. 7 flows into suction side, pressure-reducing chamber 102, then will hinder the flowing of above-mentioned suction air flow, thus can occur cannot in Conductivity of Fiber hand-hole 106 problem of vacuum fibers bundle.Consider this problem points, as shown in Figure 7, the above-mentioned formation recorded in first technical literature is that the diameter made by the diameter of rotating room 104 than aspirating pressure-reducing chamber 102 is larger, and forms ladder between suction pressure-reducing chamber 102 and rotating room 104.Because the part of this ladder plays a role as necking part, the swirling eddy in rotating room 104 is therefore made to be difficult to flow into suction side, pressure-reducing chamber 102.Thus, due to the situation of the flowing hindering suction air flow can not be there is, therefore think and fibre bundle can be aspirated in Conductivity of Fiber hand-hole 106.
On the other hand, as the above-mentioned formation recorded in first technical literature, when arranging ladder between suction pressure-reducing chamber 102 and rotating room 104, then rotating room 104 will have the part (bight 107 of Fig. 7) of band corner angle in suction side, pressure-reducing chamber 102 (Conductivity of Fiber hand-hole 106 side).Present inventor finds, in the above-mentioned formation recorded in first technical literature, bight 107 place that is flowing in of suction air flow forms vortex (with reference to Fig. 7), thus can occur in the situation of the movement disorder of the fiber that place of rotating room 104 rotates.If the movement of fiber gets muddled like this, then coiled fiber (reversion fiber) will reel brokenly on core fibre, or be wound around between the free end of coiled fiber (above-mentioned said rearward end in first technical literature), consequently make the quality of generated yarn become unstable.
On the other hand, proposing the requirement improving weaving speed in recent years, just there is the problem of the rotary speed of the fiber improved in rotating room 104 in order to tackle this requirement.And the general weaving speed of open end spinning apparatus is in the past about 250m/min to 400m/min.As solving the approach of above-mentioned problem, the diameter by reducing rotating room 104 can be considered, and the radius of turn reducing swirling eddy is to improve the rotary speed of fiber.
But, if reduce the diameter of rotating room 104, the region (spindle 108 around) that the region (vicinity in bight 107) then producing the disorder of suction air flow and coiled fiber rotate is close, and therefore the disorder of suction air flow will increase further on the impact that rotating fibers causes.So, in the formation of Fig. 7, due to the diameter of rotating room cannot be reduced while guaranteeing yarn quality, the problem that the rotary speed of raising swirling eddy is so therefore cannot be solved.That is, with regard to open end spinning apparatus in the past, it cannot tackle the demand improving weaving speed.
And, as the countermeasure making the disorder of suction air flow can not impact the rotation of coiled fiber, consider and form rotating room 104 diametrically enough largely.If formed like this, then because the region (spindle 108 around) that the region of the disorder of generation suction air flow (vicinity in bight 107) and coiled fiber can be made to rotate is away from, the impact that the rotation of disorder on coiled fiber that therefore can reduce suction air flow causes.
But if increase the diameter of rotating room 104, then the radius of turn of swirling eddy will become large, and consequently, the rotary speed of coiled fiber is slack-off, the demand improving weaving speed therefore cannot be tackled.If consider the installation space of open end spinning apparatus, be then difficult to form the enough large rotating room 104 can getting rid of the degree of the disorder of suction air flow.If make the diameter of rotating room 104 excessive, then in order to maintain rotating flow in rotating room 104, just must increase the amount of the air supplied to rotating room 104, thus also can there is the problem that energy efficiency is deteriorated.
Summary of the invention
The object of the invention is to, a kind of disorder of the air stream prevented in rotating room is provided, the open-end spinning frame of the yarn of stay in grade can be generated.
According to the first viewpoint of the present invention, provide a kind of fiber utilizing swirling eddy to make fibre bundle rotate and manufacture the open end spinning apparatus of spun yarn, open end spinning apparatus possesses: nozzle block, fiber guiding section, spindle.Rotating room is formed in said nozzle block.The air injection nozzle of more than 1 is formed in this nozzle block.Air injection nozzle sprays compressed air and produce above-mentioned swirling eddy in above-mentioned rotating room from the jet hole to above-mentioned rotating room inner opening.Above-mentioned fiber guiding section possesses the Conductivity of Fiber hand-hole be communicated with above-mentioned rotating room.Above-mentioned spindle is formed in the fiber that the fiber that rotated in above-mentioned rotating room passes through and passes through road in inside.With in the section of the plane cutting of the axis through above-mentioned spindle, form the part of at least above-mentioned fiber guiding section side in the section profile of the interior sidewall surface of the said nozzle block of above-mentioned rotating room, formed by with curve-like in fact.
Like this, in rotating room, the part not with corner angle in the wall of fiber guiding section side can be configured to, therefore can prevent from getting muddled in rotation indoor air stream, this air stream is flowed swimmingly.As a result, coiled fiber can be prevented to be wound on core fibre brokenly, or to be wound around between the free end of coiled fiber, therefore can make the stay in grade of generated yarn.Due to the disorder of air stream can be prevented as described above, even if therefore when reducing the diameter of rotating room, dysgenic possibility is produced to the movement of coiled fiber also very little.So, according to above-mentioned formation, the rotary speed of fiber can be improved by reducing rotating room, while maintenance yarn quality, realizing weaving at a high speed.
In above-mentioned open end spinning apparatus, formed in the interior sidewall surface of said nozzle block of above-mentioned rotating room, above-mentioned section profile is this section profile of above-mentioned curvilinear part is arc-shaped.Like this, the disorder of the swirling eddy in the rotating room of open end spinning apparatus can just be suppressed well.
In above-mentioned open end spinning apparatus, preferably, at least partially, be formed on above-mentioned section profile in the interior sidewall surface of the said nozzle block forming above-mentioned rotating room is above-mentioned curvilinear part to the opening contours of said nozzle mouth.Like this, by being form jet hole at least partially in curvilinear wall at section profile, the oval perimeters of the opening contours of this jet hole can just be extended.Like this, just can spray compressed air according to from jet hole to the mode of broadening in rotating room, thus swirling eddy can be made in the scope of broadness to impact fiber.Consequently, can with powerful power, fiber be rotated effectively in rotating room.
In above-mentioned open end spinning apparatus, preferably, opening contours whole of said nozzle mouth are formed on above-mentioned section profile in the interior sidewall surface of the said nozzle block forming above-mentioned rotating room is above-mentioned curvilinear part.Namely, when the wall of rotating room as open end spinning apparatus in the past is with corner angle, if will across the partly formation jet hole of these band corner angle, as long as then forming position offsets slightly, the shape of jet hole will significantly change, and the flowing of air also can change.So when form jet hole on the wall being with corner angle, the quality of the yarn generated easily is subject to processing the impact of precision.But when as described above jet hole whole to be formed at section profile be in curvilinear wall, even if the position forming this jet hole slightly offsets, the outlet shapes of injection nozzle does not have anything to change yet.That is, form as described above, then regardless of machining accuracy, the quality of generated yarn can be guaranteed.
Above-mentioned open end spinning apparatus possesses the suction pressure-reducing chamber portion being formed with suction pressure-reducing chamber.Above-mentioned suction pressure-reducing chamber and above-mentioned rotating room are near cylindrical or approximate circle tubular.The radius in above-mentioned suction pressure-reducing chamber is less than the radius of above-mentioned rotating room.The difference of the radius of above-mentioned rotating room and the radius in above-mentioned suction pressure-reducing chamber, below the diameter for above-mentioned air injection nozzle.
That is, in open end spinning apparatus in the past, produce the disorder of air in rotating room, the compressed air therefore ejected from jet hole expands in rotating room, and this compressed air easily flows to suction pressure-reducing chamber from rotating room.In order to prevent this situation, in open end spinning apparatus in the past, the difference of the radius in rotating room and suction pressure-reducing chamber must be increased to a certain extent, thus open end spinning apparatus is maximized.But according to formation of the present invention, owing to can make smooth air in rotating room flow, the compressed air therefore sprayed from jet hole is difficult to expand in rotating room.Consequently, this compressed air is difficult to flow to suction side, pressure-reducing chamber.So, just do not need to a certain degree to increase the difference of the radius in rotating room and suction pressure-reducing chamber as open end spinning apparatus in the past, such as can be described above, this rotating room and the difference of the radius in suction pressure-reducing chamber are set to below the diameter of air injection nozzle.Due to rotating room can be reduced like this, the miniaturization of open end spinning apparatus therefore can be realized.
According to the second viewpoint of the present invention, the spinning machine possessing above-mentioned open end spinning apparatus, will the spun yarn-winding of said flow spinning apparatus manufacture be utilized to become the coiler device of package can be provided.Like this, just package can be formed at high speed with stable quality.

Nozzle block (suction pressure-reducing chamber portion, portion of rotating room) 34, is configured in than the position of fiber guiding section 23 near downstream.Fig. 4 is the detailed profile representing nozzle block 34.Fig. 4 is the profilograph of the nozzle block 34 cut with the plane identical with Fig. 3 (plane through the axis of hollow guiding axis body 20).As shown in Figure 4, in nozzle block 34, open-work 70 is formed with.Open-work 70 is made into, to guide section shape when the orthogonal plane (plane orthogonal with fiber throughput direction) of the central axis 90 of axis body 20 is cut for circular with hollow.
As shown in Figure 3, hollow guiding axis body 20 possesses: the cylinder (columnar body) 56 kept by axis body retaining member 59.In one end of cylinder 56, be formed with the cephalic par 24 of taper.At the axle center part of cylinder 56, be formed with fiber by road 29.And fiber becomes outlet opening (omitting diagram) by the end of downstream side on road 29.Pass through fibre bundle 8 or the spun yarn 10 on road 29 through fiber, by being configured at the yarn feeding device 11 in the downstream of open end spinning apparatus 9, the outside from above-mentioned outlet opening to open end spinning apparatus 9 is sent.
The cephalic par 24 of hollow guiding axis body 20, sees by the opposite side from fiber guiding section 23 from nozzle block 34, inserts the inside of the open-work 70 be formed in this nozzle block 34 while making axis consistent.In order to enable air stream pass through, guide the interval of the outer peripheral face of cephalic par 24 of axis body 20 and the spaced apart regulation of the interior sidewall surface (wall of open-work 70) of nozzle block 34 in hollow.
In nozzle block 34, from the direct of travel upstream side of fibre bundle 8, be formed with suction pressure-reducing chamber 71, rotating room 72, taper room 73 in turn.More strictly speaking, utilize hollow to guide the outer peripheral face of cephalic par 24, the interior sidewall surface (wall of open-work 70) of nozzle block 34 of axis body 20, form approximate columned suction pressure-reducing chamber 71, the rotating room 72 of approximate circle tubular, the taper room 73 of approximate cone tubular.And although suction pressure-reducing chamber 71 is set to approximate circle column, but in fact as shown in Figure 3, the cephalic par 24 of hollow guiding axis body 20, is inserted a little by the downstream from suction pressure-reducing chamber 71 to the inside in this suction pressure-reducing chamber 71.
As shown in Figure 3, aspirate pressure-reducing chamber 71 to be interconnected with the Conductivity of Fiber hand-hole 21 of fiber guiding section 23.Rotating room 72 is interconnected with suction pressure-reducing chamber 71.So can say, above-mentioned rotating room 72 is communicated with Conductivity of Fiber hand-hole 21 via suction pressure-reducing chamber 71.Taper room 73 and rotating room 72 are interconnected.
On the other hand, around nozzle block 34, be formed with supply gas reserving chamber (supplyair accumulating chamber) 61.At spray nozzle part case 53 place, be connected with and the compressed air supply pipe (compressed air supplyingpipe) 65 omitting illustrated compressed air source and be connected.Like this, just compressed air can be supplied from above-mentioned compressed air source to above-mentioned supply gas reserving chamber 61.
In nozzle block 34, be formed with the air injection nozzle 27 of more than 1 be communicated with supply gas reserving chamber 61 rotating room 72.And in the present embodiment, although be formed with 4 air injection nozzles 27, but the number of the air injection nozzle 27 formed is not limited thereto.Air injection nozzle 27 is formed by with the elongated circular hole be arranged in nozzle block 34.To the compressed air that supply gas reserving chamber 61 is supplied, spray in rotating room 72 via air injection nozzle 27.Like this, in rotating room 72, the swirling eddy that flows rotatably along a direction of axis around hollow guiding axis body 20 will be produced.
In order to produce swirling eddy as above in rotating room 72, the length direction of air injection nozzle 27, when overlooking towards the roughly tangential direction of rotating room 72.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 in Fig. 3.But this is only in order to make figure easy understand and (conceptually) way of showing briefly.Air injection nozzle 27 is formed at the tangential direction of rotating room 72 in fact as mentioned above.So, represent the profile of air injection nozzle 27 more accurately as shown in Figure 4.
As shown in Figures 3 and 4, the length direction of air injection nozzle 27 is at downstream slightly inclined.Like this, the compressed air sprayed from air injection nozzle 27 just can be made to flow towards downstream.
In above formation, the compressed air sprayed from air injection nozzle 27, while rotating in rotating room 72, flow in the direct of travel downstream towards fibre bundle 8.That is, in rotating room 72, can produce towards the spiral helicine swirling eddy of downstream flowing.
Air discharge space 55 is formed in spray nozzle part case 53.Air discharge space 55 and taper room 73 are interconnected.At air discharge space 55 place, be connected with the illustrated negative pressure source of omission (aspirating mechanism) be configured in above-mentioned gettering container 4 through pipe arrangement 60.
Below, be described for appearance when importing fibre bundle 8 to Conductivity of Fiber hand-hole 21 in the open end spinning apparatus 9 formed as described above.
First, under the state not importing fibre bundle 8 in open end spinning apparatus 9 (state of Fig. 3), supply compressed air from the illustrated compressed air source of omission to supply gas reserving chamber 61.To the compressed air that supply gas reserving chamber 61 is supplied, spray in rotating room 72 via air injection nozzle 27.Thus, the swirling eddy produced in rotating room 72, spirally flowing through after in this rotating room 72 to downstream, flows into taper room 73.Swirling eddy flows to downstream further while weakening its flow velocity, finally discharges from air discharge space (air discharge space) 55.
On the other hand, produce towards the flowing of the air in downstream in rotating room 72 as described above, be just depressurized in the suction pressure-reducing chamber 71 that the upstream side of this rotating room 72 is adjacent, in Conductivity of Fiber hand-hole 21, produce suction air flow.This suction air flow flows into suction pressure-reducing chamber 71 from Conductivity of Fiber hand-hole 21.Thereafter, a part for suction air flow, flows into fiber and flows to downstream by road 29.Remaining suction air flow flows into rotating room 72 and converges with swirling eddy.
If fibre bundle 8 is sent to open end spinning apparatus 9 side from drafting system 7 in this condition, then this fibre bundle 8 is just aspirated by from Conductivity of Fiber hand-hole 21, guiding in suction pressure-reducing chamber 71.Direct into the fibre bundle 8 in suction pressure-reducing chamber 71, take advantage of flowing into fiber and guided to downstream by road 29 by through this fiber by the flowing of the suction air flow in road 29, be sent to the outside of open end spinning apparatus 9 from the illustrated outlet opening of omission.
The fibre bundle 8 sent from the above-mentioned outlet opening of open end spinning apparatus 9 or the end of spun yarn 10 by, the suction pipe 44 that adapter trolley 3 possesses catches, at the yarn end connector of splicer 43 place and package 45 side.Like this, fibre bundle 8 or spun yarn 10 just become, and are extended down to the continuous state of yarn feeding device 11 from preliminary roller 18 through Conductivity of Fiber hand-hole 21, suction pressure-reducing chamber 71 and fiber by road 29.In this condition, by utilizing yarn feeding device 11 to give towards the carrying capacity in downstream, spun yarn 10 being given and in rapid succession spun yarn 10 is pulled out from open end spinning apparatus 9 in tension.
Below, the appearance generating spun yarn 10 with reference to Fig. 5 to applying to twist around to fibre bundle 8 in the open end spinning apparatus 9 of present embodiment is described.And, the flowing of the air in open end spinning apparatus 9 is conceptually represented in Fig. 5 with the arrow of thick line.
Fibre bundle 8 is made up of many fibers.Each bar fiber is imported from Conductivity of Fiber hand-hole 21 in suction pressure-reducing chamber 71.The end in the downstream of each fiber to be taken advantage of from Conductivity of Fiber hand-hole 21 towards fiber by the flowing of the suction air flow of flowing in road 29, is imported into this fiber by road 29.Like this, import to fiber in suction pressure-reducing chamber 71 at least partially, just between Conductivity of Fiber hand-hole 21 and fiber are by road 29, become continuous state.The fiber of this state is called core fibre 8a.
Core fibre 8a is twisted jointly by the reversion fiber 8b (aftermentioned) rotated in rotating room 72.And although this twists around be intended to upstream side (preliminary roller 18 side) propagation, but this propagation is stoped by pin 22.So, the situation that the fibre bundle 8 sent from preliminary roller 18 is twisted into because of above-mentioned twisting around can not be there is.Like this, pin 22 just has and prevents from twisting around communication function.
Import the end of downstream side of each fiber in suction pressure-reducing chamber 71, while constantly being twisted, be twisted into core fibre 8a.But each fiber is not that its entirety is twisted into core fibre 8a, and upstream-side-end becomes free end.
When the above-mentioned free end (upstream-side-end) of each fiber enters in suction pressure-reducing chamber 71, this free end is separated with core fibre 8a and by fibrillation, and is utilized the suction air flow flowing into rotating room 72 from suction pressure-reducing chamber 71 and rushes at side, rotating room 72 (downstream).Like this, by the upstream-side-end of fiber is rushed at downstream, this upstream-side-end towards will " reverse ".The fiber of this state is called reversion fiber (reversal fiber) 8b.And, be that the fiber of core fibre 8a also can enter in suction pressure-reducing chamber 71 by side end one at its upstream originally, namely become reversion fiber 8b.
The free end of reversion fiber 8b is imported into rotating room 72, is subject to the impact of the swirling eddy spirally flowed towards downstream.Like this, as shown in Figure 5, fiber 8b is reversed just while the surface of the cephalic par 24 along hollow guiding axis body 20, rotation around the cephalic par 24 of this hollow guiding axis body 20.So the free end of reversion fiber 8b will convolution around the core fibre 8a passing through inside, road 29 through fiber.Like this, the fiber 8b that reverses just is wound on the surrounding of core fibre 8a in turn and becomes coiled fiber.Due to core fibre 8a by through fiber by carrying to downstream in road 29, therefore jointly the coiled fiber be wound on this core fibre 8a is drawn in fiber in turn by road 29 with it.
Like this, the real spun yarn 10 twisting with the fingers shape (truly twisted) will be generated.Spun yarn 10, is sent to yarn feeding device 11 by from above-mentioned outlet opening (omitting diagram) by advancing in road 29 at fiber.
By the spun yarn 10 that reels on coiler device 12 through yarn feeding device 11 as shown in Figure 1, just can finally form package 45.And, be not twisted into the fiber of spun yarn 10 when above-mentioned fibrillation and twisting because of fracture etc., take advantage of the flowing of air stream to be sent to air discharge space 55 through taper room 73 from rotating room 72, utilize the suction of negative pressure source, discharge via pipe arrangement 60.
Below, the formation of the nozzle block 34 of the open end spinning apparatus 9 of present embodiment is described in detail.
First, the shape of the rotating room's forming surface 82 forming rotating room 72 is described.As shown in Figure 4, in the interior sidewall surface (wall of open-work 70) of nozzle block 34, the part forming suction pressure-reducing chamber 71 is set to suction pressure-reducing chamber forming surface 81, the part forming rotating room 72 is set to rotating room's forming surface 82.Suction pressure-reducing chamber forming surface 81 is towards in suction pressure-reducing chamber 71.Rotating room's forming surface 82 is towards in rotating room 72.
In the nozzle block 34 of present embodiment, in the profile (Fig. 4) of the plane cutting of the central axis to guide axis body 20 through hollow, the section profile of the part of the upstream side (fiber guiding section 23 side) of rotating room's forming surface 82 is curve-like, and this part is curve part 82a.The section profile of the part in the downstream of rotating room's forming surface 82 is linearity, and this part is line part 82b.
In the open end spinning apparatus 9 of present embodiment, the radius R 1 of suction pressure-reducing chamber forming surface 81, is made into less than the radius R 2 (precisely the radius of line part 82b) of rotating room forming surface 82.In other words, the radius (suction footpath, pressure-reducing chamber R1) in suction pressure-reducing chamber 71, is made into less than the radius (footpath, rotating room R2) of rotating room 72.Like this, by making the radius in suction pressure-reducing chamber 71 be less than rotating room 72, even if when the compressed air of the then interior ejection in left-hand tools room 72 expands, this compressed air also can be made to be difficult to flow to suction side, pressure-reducing chamber 71.Thus, due to can make suction air flow swimmingly to downstream effluent move, therefore just can in Conductivity of Fiber hand-hole 21 vacuum fibers bundle 8, swimmingly to suction pressure-reducing chamber 71 in guide.
As shown in Figure 4, the end of downstream side of aspirating pressure-reducing chamber forming surface 81 is connected by curve part 82a with the upstream-side-end of the line part 82b of rotating room's forming surface 82.In the profile (figure of Fig. 4) of the plane cutting of the central axis to guide axis body 20 through hollow, curve part 82a is connected smoothly with the section profile of line part 82b.Like this, be set to curve-like by the section profile of the upstream side (fiber guiding section 23 side) by rotating room's forming surface 82, just can be configured to the part not with corner angle in rotating room 72.Like this, with compared with the conventional art (Fig. 7) that there is the part being with corner angle in rotating room, suction air flow can be made to move to downstream effluent swimmingly, the disorder of the air stream in rotating room 72 can be reduced.So, due to the movement of the reversion fiber 8b in rotating room 72 can be made to stablize, the winding etc. between the free end of the fiber 8b of therefore can preventing from reversing.By reducing the disorder of the air stream in rotating room 72 like this, the compressed air of ejection in rotating room 72 just can be made to be difficult to expand in this rotating room 72.
In the present embodiment, the section profile of curve part 82a becomes arc-shaped specifically.By the section profile of rotating room 72 is set to arc-shaped, just can in rotating room 72, air stream be made to flow swimmingly.
Below, the air injection nozzle 27 of present embodiment is described.
As previously mentioned, air injection nozzle 27 by by its length direction towards rotating room 72 tangential direction formed.So air injection nozzle 27, at the opening contours of the part (jet hole 27a) of rotating room's forming surface 82 split shed, just becomes approximate ellipsoidal as shown in Figure 4.In present embodiment, the girth of the opening contours of this jet hole 27a is called oval perimeters.
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 in the curve part 82a of rotating room's forming surface 82.Like this, with such as form the situation of jet hole 27a in line part 82b compared with, can the oval perimeters of extended jet nozzle mouth, therefore compressed air can be sprayed to downstream broadening.Like this, due to swirling eddy can be made in the scope of broadness to act on fiber, therefore fiber effectively can be made to rotate by powerful power.Owing to being sprayed towards downstream broadening by compressed air like this, even if therefore when this compressed air expands in rotating room 72, this compressed air is also difficult to towards upstream side (suction side, pressure-reducing chamber 71) diffluence.Like this, suction air flow just can be made smoothly to flow to downstream.
In conventional art (Fig. 7), jet hole due to air jet hole 105 is formed the part (symbol 109) of across tape corner angle, slightly offsets as long as therefore there is the forming position of jet hole, the problem that the opening shape of jet hole will significantly change.So the formation of the conventional art of Fig. 7, has the shortcoming that yarn quality is easily subject to processing the impact of precision.Consider this point, in the present embodiment, the opening contours of jet hole 27a is all formed in the curve part 82a of rotating room's forming surface 82.That is, in the present embodiment, be formed on can not across the position of the part of wall band corner angle for jet hole 27a.Formation according to the present embodiment, even if the position that jet hole 27a is formed slightly offsets, the shape of the opening contours of this jet hole 27a does not have anything to change yet.So, the quality of spun yarn 10 can be guaranteed independent of the machining accuracy of air injection nozzle 27.
But, in open end spinning apparatus in the past, in order to the swirling eddy in Bu Shi rotating room flows into suction pressure-reducing chamber, the difference of the peripheral radius of rotating room with the peripheral radius in suction pressure-reducing chamber is designed to be greater than to a certain degree." being greater than to a certain degree " mentioned here, such as, refer to the penetration hole diameter of air injection nozzle.This is because if the difference of the peripheral radius in rotating room and suction pressure-reducing chamber is below the penetration hole diameter of air injection nozzle, then the compressed air sprayed from air injection nozzle will from the ladder between rotating room and suction pressure-reducing chamber " spilling ".Consequently, can think when this compressed air expands, easily flow to suction side, pressure-reducing chamber.
But, in the present embodiment, rotating room's forming surface 82 and the difference (namely footpath, rotating room R2-aspirates footpath, pressure-reducing chamber R1) of the radius of suction pressure-reducing chamber forming surface 81 are set to below the penetration hole diameter D1 of air injection nozzle 27.That is, the open end spinning apparatus 9 of present embodiment is compared with formation in the past, and suction air flow can be made to flow swimmingly to downstream, and therefore in rotating room 72, the compressed air of ejection is difficult to expand.Consequently, the swirling eddy in rotating room 72 is difficult to flow in suction pressure-reducing chamber 71.So, footpath, rotating room R2 can be made less than ever with the difference (R2-R1) of suction footpath, pressure-reducing chamber R1.Like this, due to the radius R 2 that can reduce rotating room 72 compared with the past, therefore can improve the rotary speed of the reversion fiber 8b in rotating room 72 and tackle high-speed spinning.And so-called high-speed spinning refers to, be 250m/min to 400m/min relative to spinning speed in the past, spinning speed be set to the spinning of about 500m/min to 600m/min.
As described above, the open end spinning apparatus 9 of present embodiment possesses: nozzle block 34, fiber guiding section 23, hollow guiding axis body 20.In nozzle block 34, be formed with rotating room 72.The air injection nozzle 27 of more than 1 is formed in this nozzle block 34.Air injection nozzle 27, sprays compressed air and produce swirling eddy in this rotating room 72 from the jet hole 27a to rotating room 72 inner opening.Fiber guiding section 23 possesses: the Conductivity of Fiber hand-hole 21 be communicated with rotating room 72.Hollow guiding axis body 20 forms fiber by road 29 in inside, in rotating room 72 by the fiber that have rotated by fiber by road 29.In the section of the plane cutting of the axis to guide axis body 20 through hollow, in the middle of the section profile of rotating room's forming surface 82, the part of fiber guiding section 23 side is formed by as curvilinear curve part 82a.
Like this, in rotating room 72, because be configured to can part not with corner angle in the wall of fiber guiding section 23 side, therefore can prevent the disorder of the air stream in rotating room 72, this air stream is flowed swimmingly.As a result, coiled fiber can be prevented to be wound on core fibre brokenly, or to be wound around between the free end of coiled fiber, therefore can make the stay in grade of generated yarn.Due to the disorder of air stream can be prevented as described above, even if therefore when reducing the diameter of rotating room 72, dysgenic possibility is produced to the movement of coiled fiber also very little.So, according to above-mentioned formation, the rotary speed of fiber can be improved by reducing rotating room 72, while guaranteeing yarn quality, realizing high-speed spinning.
In the open end spinning apparatus 9 of present embodiment, be that for the part of curvilinear curve part 82a, this section profile is arc-shaped for the above-mentioned section profile of rotating room's forming surface 82.Like this, the disorder of the swirling eddy in rotating room 72 can just be suppressed suitably.
In the open end spinning apparatus 9 of present embodiment, whole by the opening contours of jet hole 27a, being formed at rotating room's forming surface 82 midship section profile is in the part of curvilinear curve part 82a.Like this, by being form jet hole 27a in curvilinear wall at section profile, the oval perimeters of the opening contours of this jet hole 27a can just be lengthened.Like this, just can spray compressed air from jet hole 27a to broadening in rotating room 72, swirling eddy can be made in the scope of broadness to impact fiber.Consequently, can fiber be effectively made to rotate with powerful power in rotating room 72.
As mentioned above, when jet hole 27a whole are formed at section profile is in curvilinear wall, even if the position forming this jet hole 27a slightly offsets, what the outlet shapes of air injection nozzle 27 do not have yet and changes.That is, form as described above, regardless of machining accuracy, the quality of generated spun yarn 10 can be guaranteed.
In the open end spinning apparatus 9 of present embodiment, in nozzle block 34, be formed with suction pressure-reducing chamber 71.Suction pressure-reducing chamber 71 and rotating room 72 are near cylindrical or approximate circle tubular.Suction footpath, pressure-reducing chamber R1 is less than footpath, rotating room R2.Footpath, rotating room R2 and the difference of aspirating footpath, pressure-reducing chamber R1, at below the penetration hole diameter D1 of open-end spinning nozzle.
Like this, owing to flowing with can making the smooth air in rotating room 72, the compressed air therefore sprayed from jet hole 27a, is just difficult to expand in rotating room 72.Consequently, this compressed air is difficult to flow to suction side, pressure-reducing chamber 71 from rotating room 72.So, just do not need as open end spinning apparatus in the past to a certain degree to increase the difference of the radius in rotating room and suction pressure-reducing chamber, such as can be described above, this rotating room 72 and the difference of the radius in suction pressure-reducing chamber 71 are set to below the diameter of air injection nozzle 27.Due to rotating room 72 can be reduced like this, the miniaturization of open end spinning apparatus 9 therefore can be realized.
The spinning machine 1 of present embodiment, owing to possessing above-mentioned open end spinning apparatus 9 and the spun yarn 10 utilizing this open end spinning apparatus 9 to manufacture being wound into the coiler device 12 of package 45, therefore, it is possible to form package 45 at high speed with stable quality.

Although in the above-described embodiment, rotating room 72 adopts approximate circle tubular, but is not limited thereto.Such as also as the conventional art of Fig. 7, rotating room can be formed with approximate cone-shape tubular.But, because rotating room 72 needs to produce swirling eddy, be therefore preferably circular with the section shape during plane cutting orthogonal with fiber throughput direction therein.
Although the shape in suction pressure-reducing chamber 71 adopts approximate circle column, but is not limited thereto.Because suction pressure-reducing chamber 71 not necessarily needs to produce swirling eddy therein, therefore may not be circle with the section shape during plane cutting orthogonal with fiber throughput direction.
The section profile of curve part 82a in the plane of the axis through hollow guiding axis body 20 of rotating room's forming surface 82 may not be arc-shaped, as long as section profile is level and smooth curve, then no matter is which kind of shape can.In brief, as long as the part of fiber guiding section 23 side not with corner angle in rotating room 72.But, as described above the section profile of curve part 82a is set to arc-shaped, just can suppresses the disorder of the air stream in rotating room 72 especially well.
