Fine spining machine with multi-stage drafting compression unit

The application is to be 2003.08.07 the applying date, and application number is 03127446.3, and denomination of invention is divided an application for the application of " fine spining machine with multi-stage drafting compression unit ".

Technical field

The present invention relates to a kind of ring throstle,

Background technology

Use this class fine spining machine (referring to DE 19500036, DE 196 08697) of previously known, after twisting check gap, all be spun into its oneself single cord at each the root tight fibers bundle that forms on the suction roller.In the situation of production twine, the several threads of Chan Shenging is then twisted into twine like this.

Know also in the outlet roller back of drafting unit from EP 0 444 486 A2 two fiber skein are combined that this drafting unit includes some solid cylinders; Also know by means of a spindle and handle the textile yarn that these fibers become to be similar to twine with the bell-shaped piece that can rotate freely basically.Yet twine's characteristic of the textile yarn of Sheng Chaning is unsafty in this way.

In addition, AT-PS 398 086 is open, on the suction roller that provides in exit, multistage drafting unit, fiber skein is split into two parts, these two parts still combine again in twisting check front, gap then, and therefore the yarn that is spun at last just is made of a fibre bundle usually.

Summary of the invention

Task of the present invention will provide a kind of fine spining machine, and the method for type is pointed out in particularly a kind of ring throstle and a kind of front, and in this way, no matter various lines are to have or do not have twine's characteristic, can both be produced.

The target of independent claims provides the solution of this task.

More embodiment according to fine spining machine of the present invention takes from these independently claims.

Before fibre bundle twisting and reeling, fibre bundle is subjected to time dependent drawing-off and was condensed afterwards, and this also is a part of the present invention.In addition, for example from two one ribbon of flyer bobbin, can be closely on aspirator, particularly on the suction roller, and particularly after twisting check gap, they can be each other as twine in conjunction with and twisting, thus, single tight fibers bundle is given and certain spinning twist fully simultaneously.Therefore at least one fibre bundle can be by differently drawing-off.In addition, at least one auxiliary yarn can add on one or a few fibre bundle in the arbitrfary point.

By making fibre bundle and/or strip method closely, the intensity of fibre bundle has increased significantly, and disturbs the filoplume of twine to reduce when producing.Might particularly operate with less number of twists in this case, this causes again increasing produces.

If the distance that two tight fibers bundle binding sites leave twisting check gap 5 and 15mm between, and particularly approximate 10mm greatly, just special desirable especially.The lateral separation of twisting check gap location two tight fibers bundles will 5 and 10mm between, 7mm particularly.Preferably provide a device after twisting check gap, under the ruined situation of fibre bundle closely, this installs and also interrupts another root tight fibers bundle, and this is as by known to above-mentioned EP 0 444 086 A2.

About the present invention, importantly two closely fibre bundle all be separated to guide up to twisting check gap, just just be combined into twine towards the spinning apparatus direction afterwards.

By the approximating component that more or less become to tilt is suitably located, by means of guiding device, at least by a drawing-off and fibre bundle and an auxiliary yarn and the structure of the composite yarn formed can be affected closely.

What the present invention relates to is a fine spining machine that component is spinned each other.These components are to want a fibre bundle 22a and at least one auxiliary yarn 60a drafted and cohesion at least, particularly have aforesaid characteristic, it has the drafting unit and the coacervation device that are used for a fibre bundle 22a at least, thus, for fibre bundle provides guiding device, it is characterized in that a handle assists yarn 60a, 60b guide fiber bundle 22a, the guiding device 61 of 22b, these yarns are yarns chemical synthesis and/or flexible and/or smooth and/or that curl, and/or smooth or effect yarn, thus, guiding device 61 is designed to guide member 25: or at least one auxiliary yarn 60a become to be directed to obliquely at least one fibre bundle 22a, perhaps opposite, at least one fibre bundle 22a become to be directed to obliquely at least one auxiliary yarn 60a, and both twist each other, and be not diagonal angle guiding component transporting direction preferably be that axle with transportation roller 25 accurately laterally advances, another component then not therewith axle accurately laterally advance.By to more or less becoming approximating obliquely component to carry out suitable location, by at least one drawing-off and fibre bundle and an auxiliary yarn and the structure of the composite yarn that makes up can be affected closely.

In Fig. 1 to 3, described relevant with cohesion spinning and also particularly with the relevant prior art of twisting of condensing yarn, as the prior art that obtains according to DE 196 19 307.On this basis, by Fig. 4 to 7 the present invention has been described in more detail.

According to Fig. 1 and 2, two flyer bobbins 12 are installed in the frame of not drawing, by means of an import roller 37,37 ', the strip 11 that is spun into from two flyer spindles of two flyer bobbins is entered one to including the three cylinder drafting units 13 in preliminary draft zone 23 and dominant draft zone 24 by directed parallel on turning member 28.At the terminal of preliminary draft district 23 with at a pair of

roller

29,29 of dominant draft zone 24,30 ' section start ' illustrate schematically that just all know, it is equipped with band (apron) 30, this band puts in the introducing gap 14 of a pair of

outlet roller

25,26.

The bottom roller of this a pair of outlet roller is designed to have the perforation suction roller 25 of rotating shaft 36, this bottom roller includes bigger than all the other rollers substantially diameter, and the drafting unit outlet roller 26 on it and opposite constitutes the last clamping gap 14 of drafting units 13.

These strips of advancing by drafting unit 13 are directed route segment 15 along bending along outlet gap 14, one section circumference around suction roller 25, that is to say, up to the relative roller 27 of twisting check, this relative roller and suction roller 25 constitute the twisting check gap 16 of these fibre bundles together.

According to Fig. 1 and 2, the punched areas 35 of suction roller 25 spreads on the whole circumference of suction roller 25, yet but just stride across an enough big axial width, this also considers fibre bundle 22,22 ' any transverse movement, therefore two fibre bundle 22,22 ' maintenances always check the punched areas 35 between the gap to contact with outlet gap 14 and twisting.

In suction roller 25, exist the umbrella insert 32 of a bending, this insert is concentric with the suction roller, and in the zone of route segment 15, interrupt by rights, it is to arrange so simultaneously: owing to keep vacuum in the inside of umbrella insert 32, so direction of arrow 34 in Fig. 1, produced the air-flow by the punched areas 35 of suction roller 25, this air-flow produces from the outside towards inner radial ground.

Along twisting check gap 16, leave two strip combinations closely in twisting check gap 16 and twist into twine 39, this twine is directed to the traditional ring spinning yarn feeding device 17 of back, it is down rails 38 of common part to whole spindles that this device is equipped with a ring rail 18, rings 19, steel traveler 20, spindle 21 and one, therefore produces the twine that is formed by two fibre bundles twisting on spindle 21.

Total draft in the drafting unit 13 preferably be 80 to 100-doubly, thus, the drawing-off in preliminary draft zone 23 is just in 1.1 to 1.3 times common limit.

As in Fig. 2, seeing, otch in the umbrella part 32 define two suction districts 33,33 ', these two zones axially are being spaced apart, generally extend in the circumferencial direction and/or the fibre bundle direction of transfer 31 of suction roller 25, and converge towards spinning apparatus 17 each other.

According to Fig. 2 for embodiment in, suction district 33,33 ' what axially be close to, and at fibre bundle direction of transfer 31, the drafting unit that is located immediately at suction roller 25 and correspondence exports one of end of 14 back, outlet clamping gap between the roller 26, is positioned at the place that strip 11 enters.At this intra-zone, the big axial distance in suction district 33,33 ' include.Therefrom, this two suction districts 33,33 ' basis is tapered towards the central shaft minute surface that extends between them symmetrically in circumferencial direction, the notch that approximately runs parallel in end regions, or the notch that converges a little each other.

Though according to Fig. 2 for embodiment in, suction district 33,33 ' converge originate in the suction roller 25 a circumferential point 42 (referring to Fig. 2), conform to clamping gap 14, but according to Fig. 3 for embodiment in, corresponding circumferential point 42 ' on fiber direction of transfer 31, but be 14 1 significant circumferential distances from the clamping gap.This is essential, because utilize the design form of Fig. 3, has only an one thread 11 to offer multistage drafting unit 13, and in the back in clamping gap 14 because known suction district 33,33 ' disperse, must be at first by a described one thread form the

fibre bundle

22,22 of two separation '.Two defibre bundles 22,22 ' formation obtain the help of an airduct 40, this airduct extends in the diverging region, shows with dotted line in Fig. 1.

Fibre bundle 22 two separation, 22 ' each other are in after the significant axial distance, thus, this distance is so big, so that two fibre bundles 22,22 ' between bow member (connection bridge) be to have avoided at least basically, two suction districts 33 at this moment, 33 ' converge just at fibre bundle direction of transfer 31, from circumferential point 42 ', that is to say, be similar to Fig. 2, yet thus, method hereto, effectively circumferential area is shorter, therefore with respect to Fig. 2, or converge the angle and must increase, or total converge minimizing.Other possibility has been to increase the diameter of suction roller 25, has therefore increased the length of route segment 15.

Also be according to Fig. 3 for embodiment in, these two tight fibers bundles that form on the suction roller 25 just behind twisting check gap 16 just in conjunction with and twist into spinning twine 39.

According to Fig. 4, arranged a velocity variations device 52d at drafting unit 13 places, this means for engaging is in drafting unit driver 50.The drafting unit cylinder 54a of modern fine spining machine, 54b, 54c be normally by drafting unit motor 50a independently, 50b, and 50c drives, and thus, speed reduction gearing 52b, 52c are applied between these motors and the cylinder.Preferably the preliminary draft location of drafting unit 13

drafting unit cylinder

54a and 54b therebetween is connected on the first transmission device 52b, and the outlet cylinder 54c of drafting unit preferably includes its oneself the CD-ROM drive motor 50c and the transmission device 52c of appointment.Presetting apparatus preferably is connected motor 50a, on the c.

For producing effect yarn or burning strip, drawing-off in the drafting unit 13 is not to keep constant in time, but change like that as mentioned, this can finish like this: the speed of independent drafting unit cylinder is not that the speed with another drafting unit cylinder changes pari passu.This can finish by velocity variations device 52d, preferably realizes that by a differential transmitting linkage this differential transmitting linkage is connected on drafting unit transmission device 52b or the 52c.If being the speed control mechanisms by motor 50b, admission velocity changeable device and/or the inlet velocity that enters differential transmitting linkage device 52d change in time, even drive

motor

50b and 50c and they enter the driving shaft constant speed drive of

transmission device

52b and 52c, at cylinder 54a, the transmission device 52b of 54b and 54c and the output of 52c also can cause an inconstant in time rotating speed.Such velocity variations device is for example provided by Amsler company.

Differential transmitting linkage device 52d and drafting

unit transmission device

52b and 52c are bonded together, and preset other deceleration device 52a can for this differential transmitting linkage device, and a motor 50a are connected on this deceleration device.

Fibre bundle 11 is supplied with by packing 12 as rove or drafting strip, is for example supplied with by a flyer bobbin or a bar tube.Drafting strip 11 is then at three

drafting unit cylinder

54a, 54b, and 54c is last drafted, above-mentionedly discloses already mentionedly as getting in touch, and thus, in each situation, a drafting unit cylinder has been distributed a corresponding roller 27.In preliminary draft zone 23, just drawing-offs a little of drafting strip 11, and in dominant draft zone 24, but at least drawing-off 10 times, therefore in drafting process, a little less than the interior fusion of fiber gets more and more.Because the effect of velocity variations device 52d if drafting process is to carry out discontinuously now, this means a kind of interference in fibre stream so, can take by arranging that in the outlet of drafting unit 13 measure of a coacervation device 25 stops this interference.As for embodiment, illustrate a coacervation device in the drawings, it includes a cylindric ventilative drum, as main coacervating part, according to Fig. 4, this coacervating part is installed on the drafting unit cylinder 54c.Yet coacervating part 25 also can be arranged in drafting unit cylinder 54c back, that is to say with this cylinder irrelevant.As what described, must be expressed to fibre bundle on the circumference of coacervation device 25 and/or drafting strip 11 on this coacervation device at some point by additional corresponding roller 27, utilize equally another

drafting unit cylinder

54a and 54 this also be essential.The effect that is used to the coacervation device 25 that works from the internal suction air is, under the intermittently approaching situation of strip 11, come out from punched areas 35 at drafting strip 11, be combined into before (ring spinning (ringspinning)) yarn, strip is combined, also promptly cohesion is got up, and a ring spinning apparatus 17 is provided for this reason, and it is driven by spindle 21.

According to Fig. 5 a and 5b, other material is introduced to the drafting unit and/or the yarning position on fibre bundle 22 sides, particularly auxiliary yarn 60a, and 60b, they also are called core or heart yarn line.One or a few auxiliary yarn 60a and/or one or a few auxiliary yarn 60b can be arranged, and they are close to operation each other, are provided for fibre bundle 22 or several fibre bundles 22 at the point of stipulating.Auxiliary yarn for example is at bobbin 60a ', on the 60b ', and is to leave these bobbins.According to Fig. 5 a, fibre bundle 22 is advanced by roller or

cylinder

54a, 27a, and 54b, the clamping gap between the 27b etc., to the cylinder 54c that has corresponding roller 27c, thus, drafting unit cylinder 54c has formed as suction roller 25.Further described as top, the cohesion zone is moved between the clamping point between the clamping point of the cylinder 54c that has corresponding roller 27c and cylinder 54c and the corresponding roller 27d.As what in Fig. 5 a, illustrate, auxiliary yarn for example can be supplied with the first corresponding roller 27c at drafting unit cylinder 54c place at entrance side, and/or other auxiliary yarn 60b supplies with the corresponding roller 27d at drafting unit cylinder 54c place at entrance side, therefore in first kind of situation, according to Fig. 5 a and 5b, auxiliary yarn itself is embedded in the middle of the fibre bundle 22, and perhaps with regard to the supply at corresponding roller 27d place, the itself side direction is lain on the fibre bundle 22.A thread-carrier and/or thread-carrier device 61 can be provided, it can be according to the double-head arrow activity, as what in Fig. 5 b, point out, at the supply section of assisting yarn 60b1 or 60b2 to drafting unit 13, the auxiliary yarn of this thread-carrier guiding is more or less near fibre bundle 22, and according to Fig. 5 b, this is in cohesion.Therefore in yarn 39 inside, one or a few is in the auxiliary yarn 60a in the twisting process, 60b, and 60b1, the position of 60b2 is can be affected.For the schematic diagram among Fig. 5 a, suppose/be interpreted as auxiliary yarn 60a, 60b runs on the fibre bundle 22 about the center greatly as pointed at Fig. 5 b that is used for auxiliary yarn 60a.Therefore auxiliary yarn 60a and/or 60b are wrapped up by the fibrous structure 22 of twisting, and this fibrous structure is towards the direction operation of spinning apparatus and/or spindle there.In this case, auxiliary yarn 60a, 60b locatees more in the central inner of yarn 39, is batched by the ring spinning apparatus 17 at spindle 21 places equally.Yet, if according to Fig. 5 b, by thread-carrier device 61 is carried out suitable location, auxiliary yarn 60b2 more is directed to the perimeter of coacervation device 25 place's fibre bundles 22, another effect can obtain by such mode so: because the effect of ring spinning apparatus 17 and when yarn 39 twisted, this twisting around fibre bundle 22 of auxiliary yarn 60b2, the schematic diagram according among Fig. 5 b is in the twisting process simultaneously.Simultaneously other auxiliary yarn 60a, and/or other auxiliary yarn 60a, 60b1 can be positioned at more to the inside of the fibre bundle in twisting process 22 just.With different shown in the schematic diagram of Fig. 5 a and 5b, can conceive just after the clamping line 14 and/or drawing between drafting unit cylinder 54c and the last corresponding roller 27d and be arranged in the clamping gap 14 of outlet side after just introduce (entering) and assist yarn, other auxiliary yarn 60a is then taken to fibre bundle 22 in advance, for example in corresponding roller 27c front or in other corresponding roller 27d front.Supply by the auxiliary yarn of appropriate change can realize different effects in the final products that forming.The thread-carrier device 61 that also can move around in spinning process, thus, auxiliary yarn 60b2 can be brought to the inside of fibre bundle 22 more or less, has therefore produced additional effect in yarn 39.Very clear, the fibre bundle with numeral 22 marks in Fig. 5 b just just can converge later at the bite that drafting unit exports between roller 25 and the corresponding roller 27c.

According to Fig. 6 a and 6b, fibre bundle 22a, 22b can be in parallel with each other by suitable rove packing 12a, and 12b supplies with drafting unit 13.The name of different spinning components is similar to the name among Fig. 5 a and the 5b, does not therefore repeat here.As what shown for Fig. 5 a and 5b, several auxiliary yarn 60a, the supply of 60b also can realize.According to Fig. 6 b., " if approximating mode disposes suction sealing 25 to become; they can have a kind of effect so; this effect is exactly that two fibre bundle 22a and 22b itself for example combine at 14 places, clamping gap between suction roller 25 and corresponding roller 27, and they are twisted together at the outlet side in clamping gap 14 owing to the rotation of spindle 21.In addition, Fig. 5 a and 5b described as relating to, auxiliary yarn 60a, 60b is the auxiliary yarn of independence also or just, can be introduced into spinning process, thus, with fibre bundle 22a and additional fibers bundle 22b, produce an effect yarn closely.By a thread-carrier 61 of having described according to the double-head arrow at 61 places of the numeral among Fig. 6 b, auxiliary yarn 60a or auxiliary yarn 60b can do and be displaced sideways, therefore auxiliary yarn is placed on this fibre bundle 22a and/or these fibre bundles 22a that is in the twisting process, the inside of 22b more or less.According to the configuration among Fig. 6 a and the 6b, therefore produce the false twine of a cohesion, this twine is supplemented with auxiliary yarn or heart yarn line.Also can not that fibre bundle 22a and 22b are directed to corresponding

drafting unit cylinder

54a, 54b, 25 and/or 54c on, but be directed to different, in case of necessity, be on the cylinder of placement parallel to each other, therefore a fibre bundle 22a includes continuous drafting, and additional fibers bundle 22b bears interrupted drawing-off in drafting unit 13.Fig. 6 b is noted that, the perforation 25a of suction roller 25 is arranged in left side suction sealing 25 " the zone in; other suction sealing 25 " then be in the other suction roller 25 that does not draw punched areas below, auxiliary relatively yarn 60b mirror-symmetrical in the suction insert, and auxiliary yarn 60a, 60b but stops at suction sealing 25 " and the zone between 25 , be positioned at the punched areas 25a outside on drafting unit outlet roller and/or the suction roller 25.Auxiliary yarn 60a, what 60b may relate to is yarn that synthesize and/or flexible and/or smooth and/or that curl, or also can be smooth or effect yarn, and fibre bundle 22a, 22b supplies with or variation ground drawing-off in time continuously.

At Fig. 7 a, 7b, among the 7c, for guiding auxiliary yarn 6oa, 60b is to the fibre bundle 22a of drawing-off, and 22b has pointed out other possibility.For example in Fig. 7 a, auxiliary yarn 60a on the left side fibre bundle 22a place is directed into drafting unit outlet roller 25, enters straight suction sealing 25 " near.The guiding of this auxiliary yarn is finished by thread-carrier device 61.A fibre bundle 22b in addition equally also is that continuously or intermittently is drafted, and it twists into yarn 39 towards the direction operation of drafting unit outlet roller together with the component that another root is mentioned.Coacervating part the place or the suction sealing 25 of suction on the roller 25 " can with straight line (referring to Fig. 7 a) or become (referring to Fig. 7 c) move structurally.For auxiliary yarn 60a, this also is suitable for the guiding of 60b.According to Fig. 7 c, two fibre bundle 22a that will condense, 22 ' a can " go up operation at same suction sealing 25.

In contrast, in Fig. 7 b, the second auxiliary yarn 60b is placed on the drafting unit outlet roller 25 at the second fibre bundle 22b place, and perhaps auxiliary yarn 60aa is in middle heart, that is to say the direction operation of the twisting point in the plane of symmetry of this accompanying drawing below clamping line 14.According to Fig. 7 c, also be with Fig. 6 b interrelate and described the same, auxiliary yarn 60a, also may be other auxiliary yarn 60aa, be between the fibre bundle 22a and 22b that is on the drafting unit outlet roller 25, thus, according to double-head arrow, thread-carrier device 61 can influence auxiliary yarn with respect to fibre bundle 22a, the position of 22b.Punched areas on the roller 25 generally is called coacervating part, can concerning whole illustrated embodiments, all extend on the All Ranges of suction roller 25 as seen by Fig. 7 c, and these zones then are subjected to the effect of fibre bundle or auxiliary yarn.

Therefore produce following variation:

-for example according to Fig. 7 a, of being present among plying bobbin 22a and the 22b of heart yarn line locates, thus, suction sealing 25 " operation that is to say as the crow flies, with clamping line 14 transversely or becomes obliquely to move.

-according to Fig. 7 b, every on a yarn attached or core all is in a plying bobbin 22a, on the 22b; And

-according to Fig. 7 c, a single heart yarn line or auxiliary yarn 60a and particularly an other auxiliary yarn 60b are in two plying bobbin 22a, the center between the 22b, thus, the suction sealing can, single ground or together, as the crow flies and/or become (25 ") operation obliquely.
