Abstract
The invention provides an apparatus for producing a mock ply yarn. The apparatus for producing the mock ply yarn comprises a drafting apparatus, a condensation zone arranged on the downstream of the drafting apparatus and a twisting apparatus for twisting two drafted and condensed fiber strands together. An air-permeable transportation element transports the drafted fiber strands to be condensed on mutually adjacently arranged suction slits. The condensation zone is bounded by twist stopping rollers at the outlet side of the condensation zone and the twist stopping rollers nip the condensed fiber strands by nip lines. The suction slits are tapered mutually toward in the movement direction of the transportation element until only a small gap is left between them by the regulation of this invention. The gap should having a sufficient size to keep the fiber strands apart in the nip lines of the stopping rollers.
Description
Technical field
The present invention relates to a kind of device of producing charging yarn, it is equipped with a drafting system, its front roller is to exporting two ribbons of drawing-off, its downstream has one to gather the district, gather the district a ventilative conveyer belt is arranged, carry the suction slot of two one ribbons, also dispose one and define at outlet side and to gather the district, grip the resistance twist roller of ribbon and one at jaw and be placed in the twisting apparatus that gathers district's downstream co-twisted ribbon by adjacent arrangement.
Background technology
Charging yarn is with the difference of really twisting thread, the component of producing charging yarn have the sth. made by twisting identical with spun charging yarn to.Real twisting thread is then opposite, form the component of twisting thread have twist thread different with finished product another twist with the fingers to.Charging yarn adopts following manner production, and two one ribbons or rove carry out drawing-off and converge and co-twisted on a twisting apparatus in a working procedure after the drawing-off at a spinning spindle position.
If two last ribbons that form charging yarn leave the preceding jaw line of drafting system, promptly the jaw line at every one ribbon forms a tangible spinning triangle under the normal mode.Its reason is that the diameter of the ribbon of drawing-off is wider than its yarn diameter of producing.This spinning triangle contains the edge fiber, and the latter is random to be entangled in the yarn that is just forming, and this single thread of single thread and production charging yarn is gathered in the effect that is subjected to the air draught air-flow in the district of gathering in drafting system downstream.To this, drawing-off also the ribbon of no twist carried through gathering the district by ventilative conveyer belt, ribbon is by the side force set and become narrow thin.Be subjected to a twisting resistance roller the defining of outlet side if gather the district, only form very little spinning triangle at relevant jaw line afterwards, the yarn filoplume of Xing Chenging will lack like this, and all even brute force of integral body is good.
A kind of prior art of producing the device of charging yarn of the above-mentioned type is German patent DE 19860201A1.This device contains a ventilative woven belt, is used for carrying two ribbons that just gathering of drawing-off, and this conveyer belt slides past an aspiration channel.On planing surface, be mounted with two arranged adjacent, the suction slot of the operation that is parallel to each other, suction slot is covered by woven belt.The transmission of woven belt is by a nip roiler, and the latter's transmission is again to be driven by the right roller of the drafting system front roller of one side.After the jaw that is used as the nip roiler that the resistance twist roller uses, drawing-off and the ribbon set gathered are together and add on a ring ingot in downstream and be twisted as charging yarn.
Based on the suction slot that is arranged parallel to each other, gathering the ribbon that has gathered of distinguishing terminal just like gathering district's entrance side identical spacing like that.This spacing was original just bigger, because jaw line place enters the ribbon broad still that gathers the district before drafting system, so enough spacings must be arranged each other.This causes forming forcibly long ribbon gathering the big spacing of distinguishing terminal, before this ribbon is plied to a charging yarn, has obtained twisting the jaw line after.
Summary of the invention
Task of the present invention is to shorten the ribbon of formation charging yarn and improve the quality of whole charging yarn with this.
The solution of this task is that suction slot is close mutually till the ribbon at the jaw place still keeps spacing separately according to the conveyer belt direction of motion.
The spacing of ribbon is preferably mutually near a minimum spacing that arrives such as 5mm, and the size of this spacing just in time makes ribbon not contact mutually before reaching resistance twist roller jaw.Because the ribbon filoplume is seldom after gathering the district, so this little spacing is possible.Then only produce very short ribbon at resistance twist roller jaw place, correspondingly have minimum spinning triangle, thereby just after jaw, form the charging yarn that will produce.
As everybody knows in German patent DE 43 43 437 A1 that are not such, the wide ribbon of drawing-off directly pneumatically is split up into two thin fiber skein in the downstream of drafting system, enter the suction slot that gathers respectively, make ribbon separately accumulate an one ribbon again, suction slot is approaching mutually by the direction of motion of conveyer belt here.Ribbon is unified again fully in jaw line the place ahead of resistance twist roller like this, but is not to form charging yarn, but a single thread.
Advantages and features of the invention can be learnt from a following illustrated embodiment explanation.
Description of drawings
Fig. 1 in gathering the zone, the partial cross section side view of apparatus of the present invention;
Fig. 2 be the arrow II direction of Fig. 1 towards the side view that gathers the district, among the figure all rollers of Fig. 1 are economized and omit.
The specific embodiment
According to the device of the production charging yarn of Fig. 1 and Fig. 2, what its primary clustering comprised that 2, one of drafting systems are placed in the drafting system downstream gathers the 3 and twisting apparatuss 4 in district.
Reality has only been showed front roller to 5 in the drafting system 2, and it is made up of the top roller 7 of a driven bottom roll 6 and an elasticity pressurization.Under the mode known to the crowd, the apron 8,9 of a pair of guiding two one ribbons or rove 10 and 11 is placed in front roller to 5 upstream.Coequal ribbon or rove 10,11 are pressed the drawing-off direction A drawing-off of drafting system 2 to desired fineness.The draw zone of drafting system 2 is at front roller 5 preceding jaw line 12 places to be come to an end.
And then preceding jaw line 12 is two drawing-off but the ribbons 13 and 14 of no twist, should gather in gathering under the effect that district 3 is subjected to the air draught air-flow of downstream.This gathers district 3 and comprises a ventilative conveyer belt 15 that is designed to woven belt, and the direction of motion of conveyer belt indicates with B.Conveyer belt 15 slides at an aspiration channel 16 that extends through many work ingots position, and aspiration channel inside is designed to vacuum lead 17.
The conveyer belt 15 of this woven banding pattern is directed sliding past certain length areas of aspiration channel 16 outlines.Have two to betransported with 15 suction slots 18 and 19 that cover, adjacent arrangement in this sliding area, the vacuum source of not representing on suction slot and the figure is connected.For this reason, to many spinning spindle positions, in inhaling blank pipe 16, be provided with a vacuum connection tube 20.
Banded transport element 15 moves through this side tension element 21 that deviates from suction slot 18 and 19.
Gather district 3 and defined by a resistance twist roller 22 at outlet side, the resistance twist roller itself is by cog belt 23 transmissions by a top roller 7.Resistance twist roller 23 and aspiration channel 16 constitutes jaws 24, and in this jaw, two ribbons that gathered 13 and 14 are from gathering to come out in district 3 and entering into a ring ingot 26 by the air ring twizzle 25 of outbound course C by a pigtail shape.Obtain twisting jointly by this 26, two on ingot of ring ribbon 13 and 14 of drawing-off.
See from Fig. 2 that particularly suction slot 18 and 19 direction of motion B along conveyer belt 15 are progressively near till less spacing 27.This spacing 27 should be as much as possible little of suitable dimension, but its size still makes two one ribbons 13,14 on jaw 24 keep just separately.Like this, ribbon 13 and 14 gathers in gathering district 3, thereby filoplume will reduce the several millimeters of 27 needs of spacing.
As can be seen from Figure 2, two ribbons 13 of having twisted from jaw 24 beginning and 14 binding site 28 are the downstreams that are close to jaw 24, make the single sliver that forms charging yarn 1 very short.Also can see on Fig. 2, charging yarn 1 have as the identical sth. made by twisting of the single yarn that forms charging yarn 1 twisting to.
