Description
Technical field
The present invention relates to be used to prepare bobbin so that the apparatus and method of feeding winding portion.
Background technology
In industrial practice, the yarn production technology is widely current, and said yarn production technology comprises the phase I of ring spinning; Said phase I is produced cheese, next is second winding portion, in said second winding portion with the bobbin unwinding of yarn from it; Remove the fault of yarn; And being wound into yarn package again, said yarn package comprises much bigger amount of thread, and corresponding with quite a large amount of bobbins through processing.The processing of reeling is much faster than spinning, and therefore a spot of about tens spinning positions or spinning unit can be accomplished the production of a large amount of thousands of ring spinning unit.
Fill the transfer between two procedure of processings of bobbin from the fine spining machine to the bobbin winder of yarn, and the transfer of empty spool from the bobbin winder to the fine spining machine carried out through directly and individually between two process segments, shifting bobbin in so-called " winder ".In the automatic winder that great majority are imagined at present; Pandemic is to utilize peg (peg) supporting member to move the technology of bobbin and spool; So that bobbin and spool are placed on conveyor belt or the similar movement parts, said conveyor belt or similar movement parts are used for transporting one by one above-mentioned bobbin and spool.
Therefore generally speaking, in winder, fine spining machine is connected on the bobbin winder, said bobbin winder per hour has the spinning capacity that the doff ability substantially exceeds fine spining machine, can accomplish whole spinning production within the specific limits and does not have the dead time.
Generally, in the prior art, the bobbin that comes out from fine spining machine has them around the reel end portion of yarn of the specific number of turn of the package of bobbin or its substrate.Also according to prior art, the preparation of bobbin is on bobbin winder, to carry out, and before it comprised one of them winder station of automatic winder in feeding simultaneously, processing was carried out with several steps.The end portion of yarn on bobbin must stretch, and makes yarn leave the substrate of spool simultaneously, and from the outer surface unwinding certain-length of bobbin.Then with the yarn cut-to-length and insert in its upper end of spool; Winder station-feed new bobbin on it when beginning unwinding-can be from the upper end drawing of above-mentioned spool at each; Yarn is connected with the terminal yarn tail front bobbin, that in package, can get; Restart then to reel, machine until package.In addition generally speaking, still reel above that if bobbin has the residual yarn of considerable worth recovery, then need this preparation be used for from the bobbin of the new bobbin of fine spining machine and the incomplete unwinding of minority the two.
Therefore, the preparation station of bobbin requires have certain time interval to prepare each bobbin under the bobbin winder situation, and therefore they have limited the coiling ability.Especially for the bobbin winder that is made up of many winder units, they require each bobbin winder to have a plurality of preparation stations; For winder situation especially like this, said winder must each bobbin doff of waiting for from connected fine spining machine, so that restart processing.Increase the bobbin be positioned on each bobbin winder and prepare the unit and significantly increased their total length, transportation route, and therefore increased machine cost.

The specific embodiment
For problem relevant and the technical solution of promoting understanding,, should remember that simultaneously every spinning machine all comprises a plurality of spinning positions of aiming at along its surface with reference to the conventional scheme that Fig. 1 explains whole spinning unit with ring spinning.Each spinning working face all comprises hundreds of such stations; Described station normally obtains their driving from motor; With the function that obtains them from dispenser unit, above-mentioned motor drives along longitudinal axis, and above-mentioned dispenser unit is along the machine assignment station.
Sliver 1 is from the package that is suspended on spinning position top, and delivers at first forward in the drafting unit 2, and above-mentioned package is not shown in the drawings for the sake of simplicity.This generally comprises many sliver actuators under ever-increasing linear velocity; These actuators make this sliver attenuate through the fiber that constitutes sliver is slided between actuator gradually.In Fig. 1, as an example, what illustrate that the drawing-off group has an a pair of beginning is with 3 and 4, wherein wears 3 down and is driven into motion by the knurled segment 5 of longitudinal rod 6, the same with adjacent spinning position, and according to arrow direction rotation a).
Wearing 3 route down approximate is triangle, and confirms that by common terminal pole 7 said terminal pole 7 extends in the vertical.On to wear 4 be static, and be driven into according to arrow b by wearing 3 down) the direction motion, on wear 4 by on the supporting member that covers be pressed in down and wear on 3, for simplicity, the supporting member that covers on said is not shown.On to wear 4 route also approximate be triangle, and confirm by roller 8 with by fixed terminal bar 9.
With 3 and 4 downstream, place a pair of drawing rollers 11,12, said drawing rollers 11,12 are applied to last drawing-off on the sliver because they have a linear velocity greater than above-mentioned with 3,4 linear velocity.Following roller comprises the groove section 11 of longitudinal rod 13, said groove section 11 share with adjacent spinning position and according to arrow c) the direction rotation.Above relative roller (counter-roller) the 12nd, static; And the supporting device (not shown) that is also overhang is pressed against on the roller section 11; Said roller section 11 drives the jaw rollers towards according to arrow d) the direction rotation, refining simultaneously sliver is inserted between them, and produces yarn 20.
The mode of yarn 20 usefulness rotation is rotated around bobbin, simultaneously owing to centrifugal force forms so-called " air ring ".Air ring produces sizable stress on yarn 20, and can use a retaining ring (containment) 28 restrictions, and said retaining ring 28 general diameters are greater than the diameter of bobbin 25.Air ring retaining ring 28 is fixedly mounted on its platform, said platform ability vertical motion, however above-mentioned retaining ring 28 is kept above the level of platform 24.
The twisting of yarn causes by the rotation of bobbin 25, and propagates together with relevant stress, rises to this point that the sliver of yarn 20 is discharged by final drawing-off cylinder 11,12 simultaneously.Therefore; For with regular mode with twisting reel for yarn on bobbin 25, along with yarn forms gradually, must yarn be distributed in the differing heights place on the bobbin; Change simultaneously the level of the little ring 22 of rotation that is carried by loop bracket platform 24 continuously; Continuously according to arrow e) towards both direction motion and adjustment deposit (deposition), so that rise arrow e continuously) mid point of advancing.The deposit of the yarn 20 on bobbin 25 generally begins at the place, bottom of bobbin; And upwards be grown in the overlying strata of band taper enhancement, a series of slow upstroke that above-mentioned taper is promoted with loop bracket platform 24 then obtains with the downward movement of lacking slightly through unexpected.The purpose of this winder method is to make bobbin become conical by its shape basically, so the bobbin result is very closely knit, so yarn do not rupture at unspooling operation, and therefore yarn is to carry out unwinding through the unwinding successively of tapering part above bobbin basically.
According to the present invention, bobbin lead ingot 30 usefulness following manner are processed.Guide ingot 30 comprises:
-following cylindrical shape part 31, said following cylindrical shape part 31 always keeps below the level of advancing of loop bracket platform 24, and reception carries 37 rotation drive movement;
-base part 32, spool 26 are close on the base part 32, and base part 32 is configured as band shape nut simultaneously, and the yarn tail may be limited on the above-mentioned collar nut,
-cylindrical shape part 33; Said cylindrical shape part 33 is above collar nut 32; The diameter that has is littler than spool 26 internal diameters; And length is bigger than the length of above-mentioned spool 26, in case so its terminal part 35-spool 26 be assemblied on the holder for package former spindle 30-stretch out from the top of spool 26 significantly, and can be for example through the yarn circle of a plurality of mutual superposition reel it and with bound on it.
The length of the part of stretching out from terminal part 35 may be limited in the 8-15mm scope, and said length range enough is used for during rising the bobbin of accomplishing, reeling and keeps the purpose of yarn coil.Along this part, its cylinderical surface can be processed the different schemes of the adhesive effect with the yarn that is used to change coiling, and is as shown in Figure 6.
As an example, the preparation bobbin is implemented as follows.Spinning process on the ring throstle is managed with control module through management, the amount of thread of being produced in above-mentioned management and the bobbin 25 of control module detection on each fine spining machine unit that reaches by rice.Before this fine spining machine unit replaces them at the doff of the bobbin of accomplishing 25 with new spool 26; Beginning bobbin complete process; New bobbin must be wound on the new spool, parallel work-flow on all spinning units simultaneously, and above-mentioned spinning unit comprises ring throstle.
Fine spining machine has the doff device, and said doff device can rise, so that with a series of independent clips all bobbins 25 of on whole spinning units, accomplishing of holding with a firm grip simultaneously; Above-mentioned clip takes out bobbin; So that rise them, from the holder for package former spindle 30 that they are fitted thereon, take out bobbin simultaneously, and put down then; So that they are placed on each supporting member, said each supporting member constitutes the transportation system of winder.Provide same device to take out empty spool 26 then, and they are assemblied on the holder for package former spindle of removal bobbin 25 in the aforesaid operations.
First preparatory phase of the bobbin of accomplishing 25 is shown in Fig. 2: loop bracket platform 24 is raised to highest level, so that the little ring 22 of rotation is placed on the winder (winding) 40 of the yarn 20 on the upper end part 35 of holder for package former spindle 30.Temporarily yarn 20 is strapped in the purpose on the above-mentioned part 35 in order to reach, the yarn circle of a small amount of winder 40 is just enough.Thereby the length of this winder can utilize, so that insert the inside of spool 26 of the bobbin of doff.
As shown in Figure 3, bobbin is accomplished and is bound to normally in the substrate of spool 26.For this reason, loop bracket platform 24 is transferred to floor level, so that the little ring 22 of rotation is placed on the winder 41 of yarn 20 on the collar nut of part 32, bobbin is close on the above-mentioned part 32.In order to reach yarn tail 20 is strapped in the purpose on the above-mentioned part 32 firmly, the yarn number of turns of winder 41 is just enough in the 5-10 scope.All holder for package former spindles 30 all stop and interrupting spinning, begin actual doff operation simultaneously.
As shown in Figure 4, then 24 lockings of loop bracket platform are in extreme lower position.Himself rise on hold with a firm grip the top and making of spool of bobbin 25 of clip 45, from holder for package former spindle 30, takes out bobbin 25 simultaneously.Generally, clip 45 comprises rigid cylinder shape ring 46, and portion has a doughnut 47 within it simultaneously, and said doughnut 47 can be inflated with compressed air.Therefore clip 45 can be provided for engaging the yarn main body on the bobbin 25 that is wound on completion, the spool 26 that perhaps engages it top of yarn of not reeling.Under two kinds of situation, the lateral dimension of doughnut 47 is definite like this, so that under the situation of the chamber of unaerated, can be easy to chamber 47 is inserted in main body or the spool 26 of the bobbin of accomplishing 25 or from both, taken out.Give chamber 47 inflations with bobbin 25 lockings again with compressed air, and can rise and move bobbin, can make bobbin after motion, become free and discharge compressed air through applying necessary power.
In Fig. 4, clip 45 has been locked the top of bobbin 25, and has risen to the intermediate point of its lifting travel, so that from holder for package former spindle 30, unload bobbin 25.Rise thread-carrier 21 so that prevent to disturb doff.Yarn 20 remains on the side that bobbin 25 clamped by clip 45, and in that it is bound on the collar nut of the part 32 of holder for package former spindle 30 on the opposite side.Because so the rise pulling function that clip 45 is applied is the intermediate point cleaved of yarn 20 between clip and collar nut.Therefore bobbin 25 is unloaded from holder for package former spindle 30, and loosen the yarn winder 40 on its end portion 35, drop on the inside of spool 26 simultaneously, begin the unwinding of bobbin and remain on when beginning to reel capable of using simultaneously.To be placed on from the bobbin 25 of its holder for package former spindle 30 doffs on one of them peg fulcrum post then, said peg fulcrum post plays the supporting mass (carrier) of whole bobbin and empty spool.
According to improved embodiment of the present invention, clip 45 works on the top of spool 26-as shown in Figure 4-and be equipped with blow-out nozzle (not shown in the accompanying drawing for the sake of simplicity).When unclamping the spool of the bobbin on the peg of doff at it through exitting to film 47, this blow-out nozzle makes the whole yarn tail of winder 40 get into inner at the inner injecting jet air of spool simultaneously.
In Fig. 5, holder for package former spindle 30 is shown, said guide ingot 30 has received new spool 26 and has been used to begin the production of new bobbin.Yarn tail from drawing-off group 2 passes little ring 22, and is bound on the collar nut 32.From here, can retrieve the yarn tail of winder 41, be used on the spool of changing, beginning once more spinning.
In Fig. 6, show several embodiment of the end portion 35 of holder for package former spindle 30.Different schemes A illustrates cylindrical shape end portion 35, and said end portion 35 is machined to has hollow opening 51 a little, so that confirm the placement level of winder 40.Different schemes B illustrates cylindrical shape end portion 35 and in its peripheral part 52, processes more coarsely, for example is machined to and has annular knurl, so that help the yarn circle of yarn 20 is sticked to desirable height place.Different schemes C illustrates the cylindrical shape end portion 35 that can change length.It can be processed can be with respect to following 33 motions of cylindrical shape part and replacement.For example, part 35 can be used screw thread 55 or install with the mechanical connection of equivalence.Alternatively, same end portion 35 can be tightened it or unscrew with respect to 33 liters of lower parts or fall through beginning from its screw thread 55, possibly insert the thickness of axle collar form simultaneously.
Different schemes C can make ring throstle be used for spool 26 processing of different length, is wound on the either large or small yarn yarn batches on the bobbin 25 so that produce.In this case, can on the holder for package former spindle 30 in the ring spinning unit, prepare the end portion 35 of appropriate length, these parts 35 that form the outstanding level of above-mentioned end part meet the length of new spool for use.
Between the doff operational period, a plurality of bobbins 25-in their terminal yarn end insert under the situation in the spool-be transported to transportation route then, be used to transfer them to bobbin winder.
Compare with the bobbin preparation system that prior art adopts, have considerable advantage according to preparation method and the device that still is positioned at the bobbin on the fine spining machine of the present invention.At least simple one said below advantage of the present invention was worth.
With respect to the technical solution at the winder hands-operation of present use, bobbin winder therefore can be with direct use the new Cylinder feeder that has prepared of time delay not.Uncompleted those bobbins of bobbin that fraction is not accepted and spinning unit can prepare outside production line transportation branch through the Assisted Preparation unit; And do not influence the normal winding process; Strict time restriction needn't be considered in said Assisted Preparation unit, and can under best output capacity and maximum reliability, work.
Significantly eliminate on each bobbin winder the streamline of bobbin and prepare the unit and simplified its operation, and significantly reduced the total length of the machine of machine transportation route, and therefore reduced machine cost.The bobbin of the preparation completion on fine spining machine requires to revise a little, and said modification does not increase machine cost basically, but the difference of some members that requirement has been adopted is used.
