Description
The present invention relates to method according to the operation drafting system of the preceding explanation clause of Patent right requirement 1 independently and 2, relate to according to the controller of the drafting system of the weaving loom of the preceding explanation clause of Patent right requirement 12 and relate to weaving loom with described controller according to Patent right requirement 13.
Prior art
Operate the method for drafting system known dawn in textile technology.Publication EP 121 97 37, EP 807 700 and EP 137 57 09 have described the method for this form.Yet as obviously finding out from the announcement of having mentioned, the present invention is particularly suitable for operating the drafting system that belongs to open-end spinning frame.In open-end spinning frame, fibrous composite is by a kind of spun yarn in the multiple air flow.
Yet the known method of operation drafting system has shortcoming.This is for the drafting system that belongs to open-end spinning frame or particularly like this for the drafting system that the fibrous composite of drawing-off is delivered to according to the spinning unit of open-end spinning process work.The shortcoming of the known method of operation drafting system is: joint quality can not be always satisfactory.Term " joint " is understood to mean " seam " in the yarn, after for example breaking aborning, locates yarn in " seam " and " is connected " once more or " hanging up ".Usually, joint by at existing yarn end place or the fiber that spins other on every side produce.Joint constitutes yarn end and additionally spins actual overlap joint section between thereon the new fiber.Therefore usually form actual undesirable thickness portion (place).Ideally, joint or docking point should be as broad as long with remaining yarn (part), and this is particularly like this for intensity and fiber quality.In the effort that realizes this perfect condition, various possibilities are disclosed in the above-mentioned announcement.For example, the fibrous termination of butt joint nidus is narrowed down and/or delivery ratio still less fiber under the steady state operation subsequently in the overlap joint section.
Yet, in addition, in known devices, also have other the present invention to plan the problem that solves now.
Really say, once find: when drafting system is devoted oneself to work when middle, therefore in relevant roller is devoted oneself to work to quilt or when being accelerated, the velocity of rotation curve is superimposed upon on the corresponding butt joint speed.By roller to producing this stack (cross to be in harmonious proportion and dash down) from pausing to their the corresponding butt joint speed or the quickening of butt joint velocity of rotation, when having reached the butt joint velocity of rotation for the first time, described stack has formed the right non-constant velocity of rotation curve of roller, therefore formed the drafting system roller between non-constant velocity of rotation than (seeing the explanation of Fig. 2 and back).Usually, in drafting system, to during accelerating to operating rate or after just having arrived fixing butt joint speed, just begun mating operation at roller.In other words, roller never is considered in the production of joint up to now to accelerate to the stack during the butt joint speed at it.Like this, up to now, produced under the non-constant velocity of rotation or cause drawing-off drafting system two rollers between non-constant velocity of rotation than under the joint that obtains.Exactly, because right toning and the Xia Chong of roller produced drawing-off coarse or that change in fibrous composite.When this fibrous composite that changes the ground drawing-off combines with yarn end, thereby during the generation joint, then this joint also has quality fluctuation.Consequently: in the overlap joint section of joint, great majority are to have produced unallowed thick position, usually are thereafter unallowed thin positions.On the contrary, be in the overlap joint section, to produce thin position or butt joint falls flat.
Therefore the purpose as basis of the present invention provides the method that operation is used for the drafting system of drawn fiber composite, utilizes described method to avoid the quality fluctuation in the joint or it is reduced to minimum.The purpose that also is considered provides the method for operation drafting system, and in described method, fibrous composite is from the starting just drafted with correct draw ratio.This or these purpose utilizes the feature in the Patent right requirement 1 and 2 independently to reach.
Explain the beneficial effect of the method according to this invention below with reference to Fig. 1 and 2.
Fig. 1 shows drafting system commonly used 1, and the method according to this invention can be applied to wherein.For this purpose, drafting system 1 has: front roller is to 3 and have the rear roller of jaw line 5 to 4.Drafting system 1 can have other roller to 7.Drafting system 1 is used for drawn fiber composite 2.For this purpose, roller rotates with different speed or peripheral speed 3 and 4.Front roller to 3 and rear roller to the 4 so-called main drawing areas 8 that therefore constitute drafting system 1.Drawing-off also occurs in roller to (so-called preliminary draft) between 7 and 3.Usually, at front roller 3 places are had apron 20 such as the illustrated drafting system of Fig. 1, apron 20 is used to guide will drafted fibrous composite 2.Yet the existence of apron 20 is unessential for the present invention or is not absolute demand.During steady operation, fibrous composite 2 operation by roller to 7 (if present), and especially by roller to 3 and 4.In the case, fibrous composite 2 is drafted, and at rear roller drafting system 1 is left in 4 jaw line 5 places or its downstream.The fibrous composite great majority of drawing-off are handled (for example in spinning unit in the same way more afterwards; This respect is seen Fig. 4 subsequently).Then, if owing to any reason, take place to interrupt aborning or usually drafting system 1 must be devoted oneself to work again when middle, fibrous composite 2 must be directed into drafting system 1 again or correctly be located at least.Therefore the effect of particular importance is played in the position of fibrous composite termination 6.In the case no matter drafting system 1 whether have additional roller to 7 or even also have other roller right, all be unessential to the present invention.Normally such: if generation interruption aborning, the roller of drafting system 1 is to stopping in order, and fibrous composite 2 disconnects at jaw line 5 places thus.For this purpose, front roller stopped before rear roller is to 4 to 3.The result is that fibrous composite termination 6 just in time is positioned at the place ahead of jaw line 5.This respect is for example seen above-mentioned EP 137 57 09.
Devoted oneself to work once more when middle when drafting system 1 then, usually, at first, rear roller began to rotate before front roller itself restarts work to 3 to 4.Be preferably in rear roller to 4 work and front roller to the adequate time cycle is arranged between 3 the work, to guarantee: rear roller to 4 velocity of rotation curve in, be superimposed upon front roller to finishing before 3 motions by what acceleration produced.Yet, because fibrous composite termination 6 just in time is positioned at rear roller the place ahead to 4 jaw line 5, at front roller to 3 drawing-offs that fibrous composite 2 taken place after in devoting oneself to work immediately.Because after front roller was devoted oneself to work to 3, it still must accelerate to butt joint speed or operating rate, and the stack to desired butt joint velocity of rotation also takes place herein.The result is that the section that follows the fibrous composite 2 of 6 back, fibrous composite termination closely carries out drawing-off in the mode of fluctuation, therefore has undesirable quality fluctuation.If this of fibrous composite 2 " original sections " is used to produce joint, then this joint also has undesirable quality fluctuation certainly.
Also can most clearly see the generation of these quality fluctuations from Fig. 2.Especially Fig. 2 has shown that rear roller is to 4 velocity of rotation curve U
4(t) and front roller to 3 velocity of rotation curve U
3(t).At time point t=0 place, rear roller is devoted oneself to work to 4.For this purpose, described roller to 4 at time cycle t
H, 4In be accelerated, reach butt joint velocity of rotation U until rear roller to 4
A, 4(for example～5mm/msec).The acceleration of described roller is very high, because otherwise the length of selected yarn end 10 must be unacceptably.Therefore accelerate during several milliseconds, to take place.When reaching desired velocity of rotation, concerning under constant but very high acceleration situation, interrupting suddenly quickening, because physically, be impossible, so at specific time cycle t for roller
EV, 4Produced stack during this time.Same situation also correspondingly be applicable to front roller to 3 (at time cycle t
EV, 3Stack during this time).This stack continuity is depended on the right physical property of driven roller and is depended on their driver, closed loop controller and open-cycle controller how long with toning or dash down and have muchly.By using suitable closed loop controller and driver, but time cycle t
EVBe reduced to minimum.Yet because the right high acceleration of roller, it can not be avoided fully.
Therefore, when drafting system is devoted oneself to work when middle, because the result of the described effect in the original sections of drafted fibrous composite, quality fluctuation does not take place, according to the present invention, only when two rollers when being through with by the corresponding stack that quicken to produce, the fibrous composite termination (that is to say, the most preceding tip of fibrous composite), be fed to the right jaw line of second roller.This time point is used t in Fig. 2
EVEMark; At this time point, two rollers have been to having reached constant butt joint velocity of rotation (releasing as the figure of institute among Fig. 2), perhaps their stacks that is through with at least.Then, according to the present invention, the drawing-off of fibrous composite is as far back as time point t
EVEBeginning, or in other words, the fibrous composite termination should enter the jaw line of next second pair of roller, therefore as far back as time point t
EVEDrafted.If except this coordinated drawing-off, the operation of drafting system also related to the butt joint effect to yarn end, then the time started of butt joint action is put t
