Description
The present invention relates to a kind of fine spining machine with at least one multistage drafting device and spinning apparatus.
At known ring spinning method and known this ring throstle (DE 39 27936 A1, in September, 1994 number the 684th～686 page is put into practice in international weaving) in, one or two parallel rove bar respectively is directed to half of ring spindle yarn drafting system, carry out drawing-off with common drawing-off value, flowing to a Pneumatic fiber compression set on the porous suction roll under the situation of no drawing-off then.On the surface of porous suction roll (or tube) the solid compression that ribbon is subjected to pneumatic action taking place with known method, obtains positive effect by the drawing-off of fiber and condensed phase are separated here.In order to compress, remain on the lip-deep ribbon of suction roll by suction airstream and deflect vertically through drawing-off, therefore, the fiber of ribbon inside is merged individual fibers mutually by stretching and the mat effect of traversing abreast and gathers into a branch of.Generally speaking, inflatable gas stream impacts by it and helps the process that caused by swabbing action on the outer surface, thereby is in stable poised state in the air-flow that the fiber that makes separation is applying in transferring to the process that the jaw line twists.The present invention also can particularly advantageously be applied in by in the described ring spinning method of the application that is entitled as " ring spinning method and ring throstle " and ring throstle submitted to simultaneously, and the air-flow of wherein blowing is replaced by suitable air channel.Therefore the content of similar application also can be used as the reference of teachings herein.
Fiber after the height drawing-off produces about 1mm of a width or littler solid fiber skein through pneumatic compression, and this width also forms the and then twist prevention jaw leg-of-mutton base of spinning afterwards simultaneously.The result has also reduced the leg-of-mutton height of spinning.Therefore the pneumatic bunching action of fiber can influence fiber skein and accepts the twist.
The general drafting system that adopts three rollers of ring throstle.The a pair of middle roller that is positioned at high draw zone start-up portion generally is provided with two aprons, and it extends near the inlet jaw of delivery roller.
According to the difference of fineness of yarn, the drafting multiple of three roller drafting devices of feeding rove bar is 25～50 times.High drafting multiple is corresponding to fine-count yarn.The mechanical condenser of employing comes boundling fiber skein (DE 4132919 A1 between the jaw of also once terminal at the apron of main drawing area and drafting system delivery roller; DE 4141237 Al).But the effect that improves yarn qualities in this way is limited, because the friction of individual fibers on the condenser induction element causes the irregular of yarn.Therefore, to be arranged on the end of main drawing area also be not the measure that significantly improves the best of yarn qualities to condenser.
In order to reduce the wearing and tearing in the multistage drafting device, one traversing gear generally was set before drafting system, it makes the ribbon that the enters drafting system 6～10mm that traverses in the order of magnitude is time interval about one minute, but in the case such problem will appear, just adopt the suction channel of an inclined slot, its principal advantages is from throughput direction, ribbon on the front in rake joist road simultaneously pneumatic the and mechanical means of mat carry out boundling.
Because ribbon moved along front edge in the long comparatively speaking time, made the effect in rake joist road change with the process of traversing in time.
The objective of the invention is to propose the ring throstle that a kind of this paper starts described type, no matter it adopted or do not adopt traversing gear before the multistage drafting device, can guarantee that all pneumatic the and mechanical mode combine of improving of ribbon mat in the fibre-condensing district of no drawing-off comes polymerization.
The technical solution of above-mentioned purpose is, using before the multistage drafting device under the situation of traversing gear, the suction district has facing to the residing end of suction roll direction of rotation than the bigger width of distance that traverses, and dwindle gradually along the ribbon throughput direction, or the width of a 6mm arranged when not adopting traversing gear, 8～12mm particularly, and dwindle gradually along the ribbon throughput direction.
Therefore, design of the present invention is: have one axial, the suction district on linear border preferably against the direction of rotation of suction roll, have one to be slightly larger than the extension of the movement length of traversing and to dwindle symmetrically substantially along the feeding direction of ribbon in above-mentioned linear bounds.Ribbon alternately contacts with the opposed tilt boundary on left side, suction district or right side in the motion process that traverses like this, therefore, though have the motion of traversing, but still can realize pneumatic and the ribbon pack that combines of machinery and form a solid ribbon perfectly.
On the contrary, in the rake joist road of two edges setting parallel to each other, when motion was traversed in stack one, the guide situation just had obvious variation.This can reduce by the structure of leg-of-mutton and symmetrical suction district by the present invention.
Narrow output point at the suction district end that is positioned at feeding direction is very important for obtaining special fiber with excellent bar pack.
According to of the present invention, at least basically be triangular structure the suction district can with the suction district gross area obviously reduce interrelate, wherein triangle has quite big shortening at feeding direction.And from circumferencial direction, second half one of suction district only forms a slit that along the circumferential direction extends.
The present invention will be described by embodiment shown in the drawings below, wherein:

Fig. 6 is according to the another kind of advantageous embodiments of suction district of the present invention,
Fig. 7 according to the present invention to reducing the particularly advantageous version of required suction air amount,
Fig. 8 still stitches in the zone, road at Fig. 6 or straight line shown in Figure 7 with the similar profile of Fig. 3.
Fig. 1 and 2 represents that a rove bar 11 feeds three roller drafting devices 13 from the bobbin 12 that is installed in the top by a director element 28.Drafting system 13 comprise have a pair of feeding roller 37,37 ' preliminary draft district 23 and a main drawing area 24.Be provided with at the top of the end in preliminary draft district 23 and main drawing area 24 a pair of roller 29,29 ', be provided with as everyone knows on it the apron 30,30 that only schematically illustrates in the drawings ', apron 30,30 ' always extends to leading into jaw of a pair of delivery roller 25,26.
The structure of the bottom roll of delivery roller centering is the suction roll 25 of a porous, and it has much bigger diameter than other roller, and a rotating shaft 36 is arranged, and suction roll 25 forms the last jaw gap 14 of drafting system 13 together with the drafting system delivery roller 26 of counter-rotating.
Be directed into a counter-rotating roller 27 that stops the twist through the fiber of drafting system 13 dimension bar crooked distance 15 on the part circumference of suction roll 25 after output jaw 14, it forms the twist prevention jaw 16 of ribbon together with suction roll 25.
The perforation 35 of suction roll 25 is to be distributed on the whole circumference as shown in Figure 2, but only limits in the very little width on suction roll 25 circumferential wall.The size of its width should make ribbon 22 contact with meshed portion 35 all the time when considering that ribbon 22 traverses process.
In suction roll 25 inside one concentric cage 32 is arranged, it is an opening in the zone of distance 15.Because maintenance one negative pressure cage 32 in, thus produce one along arrow 34 directions radially outside in through the air-flow of via hole 35.
After the twist stops jaw 16, ribbon is issued to a traditional ring spinning apparatus 17 in twist configuration, it is provided with ring rail 18, rings 19, steel traveler 20, step rail 38 and spindle 21, and the solid ribbon 22 that stops jaw 16 to be drawn from twisting is spun into ring spun yarn 39.
Preferably 80～100 times of the total drafting multiples of drafting system, the drawing-off in preliminary draft district 23 are then only in 1.1～1.3 times of general limits.
Fig. 1,2 and 3 is illustrated in the cage 32 with taking out of forming of opening mode and only distinguishes 33 length that not only along the circumferential direction are limited in distance 15, and also is limited within the width d at width, and the width of this width and hole area 35 is roughly the same.
According to the present invention, shown in Fig. 1～3, above suction district 33, be provided with deflection screen 40 in suction roll 25 outsides, it extends on the distance between roller 26 and 27 15 basically at circumferencial direction, and extends to outside the 33 width d of suction district in axial both sides.Deflection screen 40 distance A apart from suction roll 25 outer surfaces approximate the width d of suction district 33.
Because deflection screen 40 obviously exceeds suction district 33 in side direction, therefore the pumping airflow 34 that sucks from the outside is forced to from its both sides basically axially to flow on the ribbon 22 that almost is positioned at 33 centers, suction district.Air-flow collides ribbon 22 in every respect there, but mainly be from both sides axially.This just forms the very big axial compression of ribbon and produces a splendid fiber pack, thereby forms the solid ribbon 22 of a width less than 1mm.
In main drawing area 24, produce after the height drawing-off, just can be between roller 26,27 and suction roll 25 do not having drawing-off in the fibre-condensing zone (distance 15) of formed jaw 14,16 and the situation that do not have to blow under obtain the ribbon 22 of such pack, thereby can after output jaw 16, obtain very high-quality yarn.According to fibre-condensing of the present invention, not only can eliminate the influence that main drawing area enlarges strip, but also it is carried out overcompensation, yarn qualities is improved by leaps and bounds.
In the embodiment shown in fig. 4, same deflection with suction roll 25 concentric settings shields 40 ' and have only a side that one opening 42 is arranged, basically can be by its air-flow 34 axially to flow to suction district 33.At its opposite side, deflection screen 40 ' have a sidewall 31 radially inwardly outstanding, its with deflection screen 40 that is located at this side ' on the border, side of suction district 33 flush basically.
Because this structure makes basically and with the air-flow 34 of radial effect on ribbon 22 ribbon is pressed to sidewall 31 and porous 35 simultaneously with axial and part, so ribbon pressurized between air-flow 34 and sidewall 31, thereby pack becomes the very narrow and solid ribbon of width less than 1mm.
Because a ring throstle has the spinning unit shown in Fig. 1～4 of many adjacent settings usually, so deflection screen 40 ' also can extend to an adjacent suction district from opening 42, the there have one with the sidewall of 31 one-tenths mirror images of wall, and aim at the edge of a reverse setting of suction district.But deflection screen 40 ' the end at circumferencial direction or deflection screen 40 ' itself must be provided with enough big opening so that air enters from the outside.
Main inventive concept according to Fig. 3 and Fig. 4 embodiment is, around the deflection screen 40,40 of suction roll 25 in suction district 33 and distance 15 scopes ' and the outer surface of suction roll 25 between form the slit 41 of a circular arc, air is main herein only flows into basically vertically from one or both sides.
As mentioned above, a ring throstle generally has 400～500 adjacent spinning units.In the ordinary course of things, a drawing-off arm is used for four adjacent draw zones.Therefore in addition, a suction roll 25 can be provided with a drawing-off arm, and suction roll 25 is provided with four adjacent porous regions that separate 35 in practicality, each porous region be provided with one shown in Fig. 3 and 4 deflection screen 40,40 '.
Fig. 5～7 expressions are by the radial view of pressing Fig. 1 arrow 34 directions among the different embodiment of suction district 33 of the present invention, and arrow F represents the direction that ribbon is carried.
As shown in Figure 5, suction district 33 has the shape of an acute angle isosceles triangle, and its symmetry axis 43 extends along the circumferencial direction of suction roll 25, and suction district 33 is divided into two two halves that equate and become mirror image mutually.The ahead boundaries of suction district 33 be one vertical with symmetry axis 43 or with shown in the straight line base that parallels of the rotating shaft 36 of suction roll 25.In Fig. 5 from above through the ribbon of suction district 33, base 33 ' enter slightly be shorter than base 33 ' but be positioned within the base area B fully and traverse.Thus, the ribbon of on suction roll 25, carrying through the suction district 33 right side boundary 33 " and left border 33 (seeing) that alternately reach suction district 33 along throughput direction.Therefore produce a pneumatic and mechanical ribbon bunching action that combines and the approach situation of ribbon is constant substantially." and 33 with opposite direction on the bias to the summit 33 of triangle suction district 33 " " extends on the border 33 of suction district 33.
Equally, in the embodiment shown in fig. 6, wherein represent the corresponding element with last figure with identical code name, suction district 33 is a triangle at start-up portion.Yet " form a bigger angle with 33 and its symmetry axis 43, therefore, the triangle of leg-of-mutton aspect ratio Fig. 5 is obviously low on border, side 33.Connect a straight slit section 45 along the circumferential direction in the triangular apex 33 " " of Fig. 6 back, its width is 1～2mm and extends along throughput direction F.
According to said method, in the fibre-condensing district, can obtain a ribbon equally and traverse, and at border, side 33 " and 33 " apart from B " on obtain the pneumatic and mechanical bunching action that combines.This bunching action can continue to keep and further strengthen when transporting the solid ribbon 22 of pack in straight slit section 45.
In the embodiment of the suction district 33 of pressing Fig. 7, the linear axis of suction district 33 is to base 33 ' two borders, side 44 with the concave surface of 45 one-tenth mirror image symmetries of the axis of symmetry join together.They are transformed into the straight slit section 45 that a width is 1～2mm along throughput direction.
As shown in Figure 8, be about at width 1～2mm straight slit section 45 above be provided with a row perforation 35 of suction roll 25 symmetrically, its diameter is 0.8mm preferably.
Equally, on the border 44 that concave surface diminishes gradually, can provide the pneumatic and mechanical bunching action that combines an of the best to the ribbon that in traversing, moves around apart from B.Ribbon enters the straight slit section 45 of pointing to circumferencial direction after compressing under the effect of suction airstream, bunching action continues to keep and further strengthen there.
Advantage by the embodiment on the border, side 44 that has concave surface shown in Figure 7 is: corresponding to two kinds of embodiments of the gross area and other of the suction district 33 of total suction air amount mutually specific energy further reduce, and under perfect guide situation, do not damage its pack effect.
