Description
Technical field
According to the introduction part of patent claims independently, the present invention relates to pneumatic spinning apparatus and spinning method.
Background technology
According to present technological level, the technology of spinning in gas is known.It is relevant with eddy current air spinning method, and this method is to be sent in the rotating air-swirl at an indoor fiber that is come out by the fiber supply line.Fiber is subjected to twisted in this rotating air-swirl and is spun into yarn in this way, leaves by the ingot hole of rotating or fixing spindle subsequently, and in fact this spindle is configured in the opposite of fiber supply orifice.In this technology, each bar fiber of sending eddy current to has at least an end freely to remain in a period of time in the revolution air-flow.It is fast that the advantage of this weaving techniques is considered to process velocity, and relatively quality of yarn is higher with ring spinning.
In said method, required air-swirl is produced by the compressed-air atomizer of arranged tangential in the spinning room.The compressed air that breaks away from spinning line is through extending along spindle and the exhaust passage discharge coaxial with spindle.Because spinning chamber and the exhaust passage size is less and because the supply gas pressure height, so air velocity is corresponding higher.This speed is near velocity of sound in certain zone.
In for example U.S. Pat-5 ' 528 ' 895 description is arranged by the spinning method known to the state of the art, it is characterized in that, form day crown body of crown at the upstream fiber of ingot hole import and support by air-swirl.One end of every fiber of this fiber corona is positioned at the ingot hole and becomes the part of yarn here, and yarn continuously is pulled away.A part and parcel task of this fiber corona briefly is to catch the fiber that freely rotates and bring them into spinning process.Both made that problem also exists in this structure, promptly the part fiber is not caught by the fiber corona, but dissipation is in exhaust airstream.Most of the fiber that these are lost is staple fibre, sees quantitatively, have great economy to be worth, but they lost in the spinning method known to the state of the art.
Purpose of the present invention proposes a kind of spinning method and spinning apparatus exactly, can obtain quality yarns and can reduce fiber loss with it.
This purpose can reach with spinning method of stipulating in this patent claims and spinning apparatus.
The present invention is based on a fact, and promptly in said method, the fiber that exhaust is carried is intercepted and captured, and reclaims and returns spinning process at assigned position.The first step is separated fiber and exhaust airstream in this technology, second step, i.e. and removal of contamination and aligning in case of necessity, the 3rd step taked suitable means that it is returned spinning process.According to the difference of Application Areas, adopt different feedback points, this has Different Effects to the yarn forming process.Preferred scheme below is described.
First scheme that fiber feeds back is that the fiber of recovery is turned back in the rotating fiber corona district.In revolution fiber corona center, as the eye of wind of cyclone, flow velocity is lower.The fiber that enters this district can not be subjected to the effect in the high velocity stream of periphery, thereby correspondingly deflection is little.With the yarn that this structure is produced, its core is fibrous by low twist, and one deck twisted fibers cover is twined in the outside.
Preferably sending the rotating fiber corona of fibre feeding to hole and/or one or more deep fiber by an independent fiber that is positioned at central authorities sends the hole to and carries out.Adopt the fiber guide device in order to ensure fiber at the center that optimum is issued to rotating fiber corona.This guide, conical part for example, symmetric arrangement and point to the center of rotating fiber corona basically.Suitable shape also has the conical guiding device that attenuates towards revolution fiber corona center, and the outlet in fiber feeding hole is arranged at its front end.Also can adopt asymmetric layout.
The front end of fiber guide device can have an outstanding device, and as pipe, it is the elongated fibres supply orifice in addition.The fiber guide device is without any sharp edge or step, because these things have adverse influence to stream condition; Step will seamlessly transit more favourable.The fiber guide device prevents from can produce harmful twist against twist and reach the feeding district backward by the principal fiber stream that the main feed hole around one or more being arranged in is sent to also as anti-twist device.
The fiber that reclaims mainly be those the first time feed in the stage more and more away from the complete disadvantaged staple fibre at the revolution fiber corona center at their places.If the recycled fiber of now these natural separation being collected is sent this center back to, then the yarn of Chan Shenging has more staple fibre in its cross section central authorities, and the outside is equipped with than long fiber.The difference of the methods that feed back according to fiber, this fiber will be in yarn cross section central authorities more or less.
Except the recycled fiber that feedback is arranged, also can send into the fiber that adds.This fiber can be constantly (a continuous filament), the also elastomer sent to of its extended state, and it can exert an influence to synthetic yarn.
Another kind may be with fiber, is staple fibre specifically, and initial gross separation from fibre stream to be processed so that as mentioned above, is sent these fibers back to spinning process in revolution fiber corona center.Because this procedure, the possibility of removing staple fibre in exhaust stream is little.
In order to help the forming process of yarn, can in the ingot hole, produce the suction air flow that one flows along the yarn throughput direction.This measure purpose is to help fiber, particularly staple fibre, enters the inlet in ingot hole.But corresponding suction air flow may not be relevant with the processing of the fiber of sending to from central authorities.
The fiber feeder also can be used for promoting the starting of spinning process, if insert a guide.Under certain condition, fiber is sent central authorities to and can be prevented that feeding zone from the interior fiber that holds unmanageable twisting taking place.Reclaiming the supply port of dimension and the distance between the inlet of ingot hole regulates according to fibrous material to be processed.
In said apparatus, spinning process can influence with many method affords.Except the sending to of recycled fiber, the air nozzle that the yarn feeding hole also can be designed to add influences the forming process of yarn by this.The injection of in check auxiliary air flow makes the fiber suspension of central authorities.Because the effect of nozzle, fiber initiatively drops into the yarn forming process.In addition, air accomplishes that at central injection the eddy current center hangs down the flow velocity district.
In above-mentioned spinning method, the placed upstream one fiber preparation device that the present spinning apparatus of spinning room is arranged, making the fiber in the ribbon is that spinning process is got ready, and known in principle two kinds of fiber preparation devices, this device of fiber utilization can be the spinning forming process and get ready.By refining (drawing-off) be in parastate, in second kind of device, use one or more opening rollers with the ribbon separation or be cut into fiber one by one in the drafting system that ribbon is introduced in just like EP0488007 in first kind of device.The intermediate structure that also has these two kinds of devices.Also can draw other structure of the present invention based on these two kinds of devices.
Summary of the invention
The drafting system of using as fibre-opening unit having simple in structure is seen along the fibre transportation direction in first kind of device, comprises first pair of roller, subsequently a pair of belt of Bu Zhiing and second pair of roller.The fiber of Hui Shouing can be sent the upstream and/or the right upstream of belt of first pair of roller back in principle, or the upstream of second pair of roller or downstream.If recycled fiber is carried out new drafting process, will be clear that then whether they send the drafting system upstream to.The said structure of sending revolution fiber corona center with fiber to is opposite, and at this moment general the and usual yarn of the yarn that produces on the device of being considered is not seen difference.
The fibre-opening unit having that second kind of device mentioned is based on such arrangement, and promptly the ribbon of fiber to be processed guides by supply orifice, is received by feeding roller, and is transported to the opening roller of tooth or pin from here.In this process, ribbon is pickled with grains or in wine with the feeding that will be sent to opening roller at feeding roller and is compressed.Each fiber of ribbon has obtained combing or drawing-off at least, therefore substantially parallel arrangement.Fiber is sent to air-breathing roller from opening roller, and the peripheral speed of air-breathing roller is lower, and air-breathing roller generally has a porous surface, and air can absorb from these holes, and at this moment fiber just is attached to the roller surface.In the fibre-opening unit having of second kind of structure, the fiber of recovery turns back in feed orifice, the opening roller zone, or in the air-breathing roller zone.In order to form the most desirable preparation that technology provides recycled fiber to yarn, they are preferably sent back in the feed orifice zone.

The specific embodiment
The cross section of spinning apparatus 1 shown in Figure 1.Drafting system 3 in the upstream arrangement of spinning room 2.Drafting system 3 is used to the spinning process in the spinning room 2 to be ready to the fiber of ribbon 4.Drafting system 3 comprises first pair of roller 5, and another is to roller 5.1 and a pair of drawing-off belt 6 that is arranged between them.The speed of service difference of these parts, this speed are selected to make fiber alignment and the purification of passing through, and fiber is parallel mutually by the forming process of arranging and send to the correct number that requires yarn in this process.
The compressed air that is fed to spinning room 2 by compressed-air atomizer (on the figure detailed show) is used to produce vortex 15, and by parallel with spindle 12 and discharge around the annular waste air duct 16 that spindle extends.Because be not that all fibres is intercepted and captured in spinning process, so the part fiber is arranged along with exhaust is escaped by exhaust passage 16.These fibers 17 mainly are staple fibres.The fiber 17 of discharging and exhaust flow point from, as shown by arrow A.In removal process (here detailed show), fiber 17 is without any threshing and residual impurity, is positioned and is attached in the spinning process again.Arrow B is pointed out respectively to feed back a little to E.The type of the recovery technology of fibrous material to be processed and employing is depended in the selection that feeds back point.Will experience another drafting process as fruit fiber, then their feedback points of being preferably in the arrow B indication enter.
Fig. 2 illustrates another embodiment of the present invention.In this structure, the fiber 17 that is present in the exhaust stream separates from here, reclaims and by roughly being sent to the center of the fiber corona 9 that rotates in the second fibre transportation hole 20 of coaxial configuration in spinning room 2 with spindle 12.This operation is schematically illustrated by arrow F.First and/or the second fibre transportation hole can be designed to an angle, or loads onto other device in case disadvantageous twisting takes place fiber.
The fiber of discharging with use mechanical means separating of air, or realize that under centrifugal action for example this air-flow deflects so that fiber leans on its inertia and separates.Another may be the filter that is applied in continuous cleaning.This filter can be the annular filter band of not stopping transport moving that is bearing on the roller.Exhaust is directed to by this filter bag and makes airborne fiber separated.The fibrous material that accumulates on the filter bag is recovered and feeds and get back to the yarn forming process.For example, fibrous material can be transported to air-breathing cylinder from filter bag, and this cylinder forms the parts of fiber preparation device.In removal process, collected fiber does not contain any impurity if desired, in line row and be compressed into ribbon, so that be that the yarn forming process is done optimum the preparation.This removal process is preferably on the drafting system to be finished, perhaps with a fiber opening device that provides for this purpose respectively.
On the second fiber supply orifice, 20 sides one first fiber supply orifice 21 is set.This first fiber supply orifice 21 is with respect to the axis bias of spindle 12, be used to supply to be processed, from trailer system or the fiber 7 that transports from said the sort of fiber opening device (the two is all detailed showing on figure).Fiber 7 is carried to along fiber guide device 14.1 in the scope of rotating fiber corona 9, and the fiber 10 that its end is rotated in this scope is intercepted and captured and is attached in the yarn forming process.
Fiber guide device 14.1 and spindle 12 coaxial arrangement and the fiber guide surface 22 of tapered extension is basically arranged, this cone part is flat, and attenuates towards ingot hole 11, its front end can have a protrudent pin (visible DE4431761 or US-5 ' 528 ' 895).The second fiber supply orifice 20 extends and coaxial with it and reach the end in that fiber guide device 14 is inner.The outlet 23 of the second fiber supply orifice 20 is provided with facing to ingot hole 11.Fiber guide device 14 plays a part anti-twist device, prevents that the fiber of supplying 7 from disadvantageous twisting taking place, and it just in time puts in first supply orifice backward.
Be not that all fibers that provide 7 are all intercepted in the yarn forming process, some escapes in the exhaust passage 16.These fibers 17 mainly are relatively shorter fibers, absorb the yarn forming process not quite easily.These fibers 17 in the implementation method shown here are recovered and with after the second fiber supply orifice 20 is delivered to the central authorities of rotating fiber corona 9.In this structure, these fibers mainly are positioned at yarn cross section central authorities, and its outer bread than long fiber.Because the central area flow condition of revolution fiber corona 9 is steady relatively, so the risk that staple fibre is taken away with exhaust is little.
Structure in 20, the 21 other two kinds of outlets of fiber supply orifice shown in Fig. 3 a and the 3b.Press CH1845/00, cancelled the fiber guide device of taper, replace fiber output seamed edge 24.The advantage of these seamed edges is owing to flow conditions special in spinning room, and they help to carry high-quality especially yarn.
Shown in form of implementation in, in the outlet that one second fiber supply orifice 20 is arranged below the fiber output seamed edge 24 of the ingot hole 11 imports biasing of spindle 12.Fiber 7 to be processed is sent into spinning room 2 by the first fiber supply orifice 21 and is transported to via output seamed edge 24 in the zone of revolution fiber corona 9, is incorporated into the yarn forming process therein.The anti-twist device effect is played on fiber output limit 24, prevents that fiber 7 to be processed from disadvantageous twisting taking place and turn back to the fiber supply area of the first fiber supply orifice 21.
Structure difference shown in Fig. 3 a and the 3b is that the second fiber supply orifice 20 has a jut 25 in the structure of Fig. 3 b, makes the central authorities of fiber near revolution fiber corona 9.Outlet by regulating the second fiber supply orifice 20 and the distance X between 11 imports of ingot hole can additionally influence the yarn forming process, and the jut 25 in this structure is designed to the uiform section pipe, protrude on the wall 26 of spinning room 2.This pipe reaches the center of the rotary air vortex (not detailed showing on the figure) of bearing and turning fiber corona 9.Jut 25 is designed to it can not have an adverse effect to the mobile of rotation vortex, for example causes disadvantageous eddy current.
In order to influence the yarn forming process specially in addition, fiber supply orifice 20,21 one or both of produces the air-flow of directive spinning room 2 inside simultaneously.In addition, perhaps in other words, the ingot hole also can produce windstream.In case of necessity and spinning apparatus design proper, also the second fiber supply orifice 20 can be used to the starting process of spinning, if it plays the yarn effect of picking up.
Fig. 4 illustrates another embodiment of the present invention.In this structure, fiber 17 separates in exhaust passage 16 with exhaust, reclaims and deliver to by the second fiber supply orifice center of revolution fiber corona 9.Fiber 17 by a moving annular filter band 50 and exhaust flow point from.Filter bag 50 in this structure is designed so that the fiber 17 migration certain distances that separate and is delivered to air-breathing roller 51.Air-breathing roller 51 in this structure is arranged in the upstream of the second fiber supply orifice 20, helps it simultaneously and mixes.Air-breathing roller 51 can also be worked in coordination with fiber opening device.Filter bag 50 be designed to make fiber 17 and exhaust flow point from but can remove residual particles 52.This process is represented with arrow 53.The belt filter bag 50 that replaces service firing, fiber also can be used as in the flexible pipe Returning flow that is fit to.
Fig. 5 illustrates a spinning apparatus 1, and fiber opening device is positioned at the upstream, is similar to the applicant at the device described in the CH1845/00.Fiber opening device 30 comprises a feed hole 31, is used to send into fiber 7 to be processed, arranges a feeding roller 32 and a feeding trough 39 in feed hole 31 exits, and this guide plate is used for fiber 7 to be processed is transported to the opening roller 33 that tooth or pin are housed.In this course of conveying, threshing and residual impurity 35 were eliminated and discharge through first exhaust passage 38 of correspondence in the phase I.Fiber 7 is transported to air-breathing roller 34 from opening roller 33.Air-breathing roller 34 is usually designed to the roller of porous surface, air absorbs through this porous surface, so that fiber 7 sticks on this roller surface, in course of conveying, fiber sharply turns to, and remaining threshing 35 and residual impurity 35 are eliminated and take away by another exhaust passage 38.Fiber 7 usefulness one transferring roller 40 to be processed is directed to fiber feed hole 36 from air-breathing roller 34, reaches spinning room 2 through this.
In the embodiment of the invention here, the fiber 17 that is included in the exhaust is separated, and reclaim again in case of necessity, and 37 be transported to opening roller 33 through the hole, be that the yarn forming process is prepared again with these opening roller 33 fibers.The fiber of removing laterally incision makes any remaining threshing separated.In the structure shown here, from exhaust separate staple fibre with from the mixed with fibers to be processed of feed hole 31.Opposite with known spinning method, owing to feed back like this, the efficient of spinning process is improved.Because send to be in the opening roller zone, take place and owing to be transported to air-breathing roller subsequently, so fiber is arranged in parallel once more and with other fiber blend.Because removal process, fiber has been done fine preparation for the yarn forming process, so that can obtain uniform yarn.
Combine by feature and also can obtain other embodiment each figure illustrated embodiment.
