Description
Technical field
The present invention relates to a kind of device of optimizing the unwinding yarn of cross winding automatic device winding head, this device has at the yarn introduction member that forms the vertical shifting of locating on the unwinding cop of cop.
Background technology
Through winding head, the cop with little yarn amount that feeding bobbin particularly forms on ring spinner (Spinnkopse or cop) is again around (umspulen) Cheng Dajuan cross winding bobbin.Walking around again in the journey, detecting the yarn defect of yarn, removing the yarn defect and change through the approximate uniform joint of yarn.Pull out again walking around in journey of carrying out through forming so-called ballooning of yarn through the head of cop at yarn, yarn bears pulling force, and its yarn pulling force finally can limit the withdrawal speed of yarn and limit the winding speed of cross winding automatic device thus.That is to say, in winding process, if do not take the actv. countrmeasure, last three/for the moment at winding process particularly, the yarn pulling force may be increased to several times of initial yarn pulling force, and this can obviously improve the danger that yarn is broken.Because yarn is broken not only and can the quality of cross winding bobbin be had a negative impact; But also can reduce the efficient of relevant loom; Recently, people attempt to improve this device, improve through this device and walk around the unwinding characteristic of cop in the journey again and improve yarn take-off speed.
In order to improve yarn take-off speed, for example advise again around the time unwinding cheese is rotated.For example in CH-PS 542781, described a kind of winding head of accurate cross winding machine, it has the bobbin of the rotating support that is used for feeding bobbin and accepts axle.Bobbin is accepted axle and is connected with driving drum through drive belt, and this driving drum is bearing in loom and vertically constantly also on purpose is connected with axle drive shaft through magnetic clutch on the axle drive shaft of rotation.When accepting shaft drying winding bobbin diameter and under the cross winding correlation circumstance, arrive predetermined size and when being in high yarn take-off speed thus, corresponding device thereof makes the bobbin of feeding bobbin accept axle and rotates and simplified yarn unclamping from the unwinding cheese thus in the opposite direction of unwinding yarn.
DE 3843928A1 has also described a kind of work winding head of cross winding automatic device.In this known winding head, the bobbin that is used for feeding bobbin is accepted axle and is being walked around journey again through pneumatic rotation.Return bobbin and accept axle and disposed brake equipment, break off in case be used to rotate the pressure air of driving, it starts automatically.By above-mentioned device; Though can reduce walking around the yarn pulling force that produces in the journey again and improving yarn take-off speed thus; But the shortcoming of bringing thus is, usually can occur for this device that the unwinding cheese yarn is uncontrollable to be unclamped and produce snarling thus.
When particularly this snarling is not noted being wound up on the cross winding bobbin, can cause the obvious decline of quality, cause whole relevant cross winding bobbin not use thus.Even snarling comes to light and by yarn clearer excision, snarling usually occurs and also can be at least the efficient of loom be had a negative impact.

The specific embodiment
Fig. 1 shows on the whole the diagrammatic side view of the cross winding automatic device of representing with Reference numeral 1.Such cross winding automatic device 1 has a plurality of identical control positioies usually between its tailstock (not shown), here be winding head 2.As known, also be not described further thus; Through winding head 2; The cop 9 that on ring spinner, forms is the big volume cross winding bobbin 15 of coiled again, they according to its processing known by manipulator group (not shown) preferably the cross winding bobbin transfer device be transferred to machinery longitudinally on the cross winding bobbin feedway 21 and be transported to bobbin loading-unload station or the similar position that is provided with in mechanical side.
The logic device that cross winding automatic device 1 also has coiling cop delivery system 3 forms usually.In coiling cop system 3, on transfer dish 8 around cop 9 or bare bobbin.In Fig. 1, only show the supply bobbin yarn section 4, reversible driving memory paragraph 4 of coiling cop system 3, to the lateral transfer section 6 and the bobbin section of returning 7 of winding head 2 guiding.
Such cross winding automatic device also generally includes a Central Processing Unit (CPU) 42, and it is regulated computer device 29 through loom bus 43 with the coiling of each winding head 2 and is connected.
The device of this winding head 2 that does not further describe in addition, is yarn tensioner, yarn clearer, waxing attachment, yarn cutting device, yarn tension sensor and bottom line sensor.
The coiling of cross winding bobbin 15 normally carries out on wind2 24.Such wind2 also has around the bobbin bank 28 of balance staff 13 motion supportings and rotates the device that keeps cross winding bobbin.Be that cross winding bobbin 15 free rotation ground supporting in winding process is being resisted against on the groove drum 14 between the arm of bobbin bank 28 and through its surface, its groove drum drives cross winding bobbin 15 through friction force.
Of Fig. 1, the yarn 31 that the head of the cop 9 of AS location is pulled out from the unwinding position at first arrives cross winding bobbin 15 through the feed carrier 11 of vertical shifting supporting of the present invention in its path.That is, yarn 31 from the cop 9 with the form unwinding of ballooning of yarn 30.For example yarn fineness of lamination coating, yarn property is depended in the formation of ballooning of yarn, when chemical fiber avivage, can receive the distance affects between cop bobbin head and the feed carrier 11.Its implication is, in whole winding process, guarantees to form when the unwinding single air ring through the determined combined action of distance between yarn fineness, winding speed and feed carrier 11 and the cop bobbin head, this guaranteed from the cop head to cop tail condition evenly.
In said embodiment, winding head also has sensing device 22, and it contactlessly detects the formation of ballooning of yarn 30.The sensing device that for example is optical detector is connected with analytical equipment 27, and this analytical equipment 27 is connected with coiling computer device 29 through data line 23.
Fig. 2-4 has schematically illustrated first embodiment of feed carrier 11 of the present invention.The yarn introduction member 17 of vertical shifting is made up of the osed top ring integratedly, and its inner diameter d is for example confirmed according to the yarn fineness of yarn 31.
Fig. 2 shows and walks around the situation that journey begins again, and Fig. 3 shows the situation of walking around the fast end of journey again.That is, pull out yarn 31 from the cop 9 that is positioned at unwinding position AS through its head, yarn 31 then is wound up on the unshowned cross winding bobbin of Fig. 2-4 in known manner.
The yarn introduction member 17 of vertical shifting supporting at first is in reference position SP, has guaranteed that in this position yarn pulls out from cop 9 through the single thread thread balloon 30 that forms.
When walking around Cheng Jinhang again, yarn introduction member 17 moves down through corresponding control apparatus 18, up to yarn introduction member 17 last arrival end position EP shown in Figure 3.Mobile cop 9 reeling conditions that depend on of yarn introduction member 17.
In addition, can be to the central control unit 42 inputs different parameter of other device like winding regulator 29 or cross winding automatic device 1.These parameters for example are the yarn fineness of yarn 31, the length of unwinding cop 9, the diameter d of yarn introduction member 7 and/or the spacing of shape, unwinding cop head 32 and yarn introduction member 17 etc.
In a replacement embodiment shown in Figure 4, in winding head 2 zones for example optical detector of sensing device 22 is set respectively, it contactlessly detects the shape that when yarn 31 is pulled out, forms ballooning of yarn 30.The shape of detected ballooning of yarn 30 is assessed in additional bonded assembly analytical equipment 27 respectively and for example is transferred in the adjusting computer device 29 of reeling through data line 23.
Regulate computer device 29 through reeling, control apparatus 18 forms best ballooning of yarn 30 through the corresponding guiding of yarn introduction member 17.
Fig. 5,6 and 7 and 8 shows many bodies embodiment of other replacement yarn introduction member 17 respectively.
For given yarn fineness and winding speed, the air ring radius receives the internal diameter in minimum vias zone (being guide eyelit 39,40,41 here) or the influence of geometric configuration.The geometric configuration of guide eyelit 39,40,41 plays a part positive to the frictional behavior between the fixing or floating support spare of yarn 31 and yarn introduction member 17, and thus yarn load is played positive role.
Especially as can beappreciated from fig. 5, in this embodiment, yarn introduction member 17 is made up of the matrix 33 by control apparatus 18 vertical shifting, and floating part 34 is set therein.Its matrix 33 has the hole of entrying 35 or 36 respectively in its cover plate zone and baseplate zone.In winding process, wanting light as far as possible through yarn 31 out-of-position floating parts 34 is also for example processed by aluminium or plastics.Floating part 34 also has through welding fixing yarn guiding ring 38, and it is processed by steel or pottery and has a guide eyelit 39, leads wherein walking around in the journey yarn 31 again.
The guide eyelit 39 of yarn guiding ring 38 can have different shapes.That is, guide eyelit 39 is for example as shown in Figure 6 has an oval hollow cross-section.Guide eyelit also can be as shown in Figure 7 with Reference numeral 4 represent rounded.Certainly guide eyelit also can be as shown in Figure 8 is polygon 41.
Fig. 9 shows the winding head according to Fig. 1, and wherein AS also installs an air ring device for limiting 50 in the unwinding position.This air ring device for limiting 50 is along with the continuous unwinding of cop 9 also limits the radiuses of ballooning of yarn thus by actuating device 51 continuous declines, and is as shown in Figure 9.
This ballooning of yarn 30 can be regarded the restricted string of a musical instrument vibration of different obviously decay as, and wherein external curve forms the intrinsic curve of rotation air ring.Free length of yarn is that the unwinding yarn position and the yarn line segment between the yarn introduction member 17 of location on the cop 9 of cop 9 can consider to be equivalent to string of a musical instrument clamping length.
The formed balloon shape of free ballooning of yarn is similar to the string of a musical instrument and vibrates normally sinusoidal vibration characteristic.The grade of string of a musical instrument vibration is corresponding to the quantity of ballooning of yarn.Relative is to confirm single air ring like this, and promptly its air ring structure does not have waist.To this, along with the increase of balloon height, when angle of lag was spent greater than 180, the first harmonic of vibration string line was seen two air rings as.This ballooning of yarn forms the inclination serious with respect to constriction, has promptly formed waist.
Similarly, when dragging the latitude angle to spend, form three layers of air ring greater than 270.This means, can influence the possible quantity that forms ballooning of yarn and to the yarn pulling force of yarn generation effect through drift.
That is to say that the yarn introduction member 17 of vertical shifting supporting can form the guide zone of motion.For whole cop 9, for example between cop 9 heads and yarn introduction member 17, form bigger distance.This distance reduces along with the increase that is unwound to ideal position.For whole cop 9, the distance between cop head and the yarn introduction member 17 preferably is about 60mm according to cop length and yarn fineness.At the ideal position of yarn introduction member 17, this distance is about half the.
Except drift, centnifugal force and air resistance also can produce very big influence to the formation of air ring.These two kinds of power and different constant and variable relating to parameters.The parameter that directly influenced by winding process mechanical technique condition also has the mean radius of air ring except drift.
As stated, when drift was passed through the position adjustments of yarn introduction member 17, the increase of the maximum of air ring radius was confirmed through the air ring device for limiting 50 that on cop 9, descends.
Realized walking around in the journey whole through vertical shifting supporting yarn introduction member 17 again, from cop 9, discharged yarn 31 by single air ring 30, this is special relevant with air ring device for limiting 50.Especially for whole cop, prevented that also the ballooning of yarn that comes off from falling on the cop tube head and cause trouble thus.
