Description
Technical field
The present invention relates to be used for the fourfold twist spindle of twisting machine, relate in particular to the device of the tension force that is used to regulate the yarn on the fourfold twist spindle.
Background of invention
In order to illustrate the technical problem that the present invention relates to better, and correctly estimate technical scheme of the present invention, can as non-restrictive example, in the exploded view of Fig. 2, provide its function with reference to the fourfold twist spindle among the figure 1.Fourfold twist spindle given here has truly reflected the device among the patent application EP1726693 of same Applicant.Fourfold twist spindle among all right referenced patent EP1007773.In these documents, disclose these and installed the more details of the function that is had.
According to Fig. 1 and Fig. 2, the twist spindles that adds that is used for the multiple twisting of filament and yarn comprises the Sheng yarn jar 10 that is used to feed bobbin 11, remains locked in the appropriate location by using for example fixing magnet M will contain the yarn jar.In general, the doubled yarn of being reeled on feeding bobbin 11 and the doubling winder is prepared respectively on the yarn package, is brought to twisting mill then.
Fourfold twist spindle also comprises two parts that direction of rotation is opposite, be respectively the last rotary part 15 and the following rotary part 16 of more close inside, both all are positioned at bobbin holder yarn jar 10 belows, last rotary part 15 and following rotary part 16 are coaxial in the ingot axle toward each other, and transmission and unwinding element 20 are installed above bobbin 11.At first will pass unwinding element 20 from the yarn F that feeds unwinding on the bobbin, the terminal of unwinding element is connected to the driving element 21 that is positioned at the bobbin top, and yarn enters the inner rotary part 15 of going up downwards subsequently, has formed the interior air ring B around bobbin.Yarn 28 enters the described rotary part 15 of going up along the radial passage, with roller 29 deflections, is passed in the axial passage in the rotary part 15 30 on the described inside.Be positioned at the above the exit of passage 30 of ingot rotating shaft when yarn arrives, yarn just passes second transfer element 31 integrally formed with following rotary part 16, passes the radial passage 32 of described time rotary part 16 inside subsequently; Therefrom withdraw from and be redirected to the top, form outside air ring B ', arrive last transfer element 33 places and also finally deliver in the gathering-device on top.For figure is simplified, do not provide these gathering-devices among the figure, gathering-device is collected in the yarn of working on the fourfold twist spindle in the package with stable and predetermined speed.Along from transfer element 21 to the stroke of final transfer element 33, yarn each in two rotary parts each the revolution in be coupled with two turns.
Following rotary part 16 is supported by the fixed mounting base 14 that supports whole fourfold twist spindle, and by external transmission device, and for example, by driving with the coaxial transmission tengential belt of spindle, spindle is then rotated by the tengential belt transmission.Following rotary part 16 passes through, and for example the epicycloid transmission mechanism of mentioning among another patent application EP1726693 according to the same Applicant of above mentioning passes motion to rotary part 15, and more details can be with reference to this patent application.One cassette part 19 is arranged in this epicycloid device 18, and this device is locked in place with being installed in the fixed magnet of containing yarn jar 10 bottoms too.
Be provided with unwinding apparatus 20 above feeding bobbin 11, this unwinding apparatus receives doubled yarn F from feeding bobbin 11.Described unwinding device 20 is positioned on the axle 13 of containing yarn jar 10, is inserted with rolling bearing 22 on interior axle 13.Whole unwinding device 20 is by same doubled yarn F driven rotary of spiral unwinding from feeding bobbin 11, the terminal ring of yarn process rotation guide arm 23 also enters the axial cavity 24 that is arranged in unwinding device 20, and unwinding is thought highly of the top of the transmitter 21 of newly guiding top arrival mitriform into.The unwinding linear velocity is by the tractive force decision of the gathering element that is positioned at downstream part, and this tractive force has also determined hour output of twist yarn output.
In order to set forth the technical problem that faces among the present invention and need to solve better, twisting process is described with reference to figure 2 and the actual speed in the spindle function.
Fourfold twist spindle for example is subjected to single driving from the axial axis of bottom rotary part 16 by pulley 17, and for example is driven with 10,000 rev/mins.Epicycloid transmission device 18 passes motion to top rotary part 15 with about 50% speed, so the rotary speed successively of top rotary part is 5000 rev/mins.
Because as indicated above, in whole stroke, each revolution of each rotary part all makes yarn F add turn twice.During twisting, the per minute yarn is through bottom rotary part 16, and obtaining twice 10000 changes, and through top rotary part 15, obtaining twice 5000 changes, and that is to say it is 30000 rev/mins altogether.If it is 600 twists that yarn F requires on every rice noodles, per minute can be processed 50 meters yarns on the four double twisting ingots, with the draft speed of the control downstream unit of 50m/min.
Because the 26S Proteasome Structure and Function that twister has, the tension force of most of yarns all are because the centrifugal force of the ballooning of yarn of high speed rotation causes.The stable technical problem of air ring is not only caused by tension value, is also caused from the erratic behavior that feeds unwinding volume on the bobbin 11 by yarn F.
Because the drawing-off effect of collected downstream device comes the yarn F of the terminal ring of spinning guide arm 23 to be pulled away from the feeding bobbin 11 that is locked in the Sheng yarn jar, this causes for example unwinding of 50m/min.At the initial skin of feeding bobbin, this 50m/min is corresponding to the spiral unwinding of about per minute 100 times: yarn F advances around feeding the slow spiral of bobbin.The resistance of yarn F unwinding and the tension force of yarn correspondence change along with the variation of yarn drawing point, helical pitch corresponding to feeding bobbin 11, the drawing point of yarn has a pulse: when yarn when feeding bobbin highest point is pulled, resistance and corresponding tension force have a minimum of a value, when yarn was pulled in the bottom of feeding bobbin, resistance had a maximum.This pulse is that length variations owing to the yarn line segment the terminal ring from feeding bobbin drawing point to rotation guide arm 23 causes, also is because the bigger or less frictional force that yarn is run into when sliding on the feeding bobbin causes.Unwinding tension difference between the feeding bobbin upper and lower be actually by rise and descent direction on the unwinding yarn be subjected to coming from that the different resistances of adjacent spiral determine.
When feeding bobbin 11 is about to use up, mention the linear velocity 50m/min corresponding to per minute 400 spirals (limiting value is 500-600) unwinding in the preamble: yarn F is around feeding bobbin 11 rotation at a high speed, and always keep spiral to advance and close tension pulse, and higher frequency.
Because yarn F continues to increase from feeding bobbin 11 unwinding rotary speeies, the traction drive that the unwinding device 20 of traction yarn F also is subjected to yarn itself begins rotation, and at first with rotation at a slow speed, speed is several rev/mins, when feeding bobbin 11 was about to use up, rotary speed became greatly to hundreds of commentaries on classics per minute.Because increase in the transmission speed of feeding bobbin 11 to the yarn F of the spiral unwinding of extending between the unwinding device 20, the resistance of unwinding also progressively increases.
This driving effect transmits via rotation guide arm 23 in the rotation.Because the tension force resistance pulse of yarn F, guide arm 23 and whole unwinding device 20 are also with impulse speed rotation, and pulse has an amplification to yarn F tension force resistance in yarn F unwinding process.In fact resistance difference when doubled yarn stretches has caused the angular coordinate of towing point and has rotated periodicity deviation between the guide arm 23, and wherein towing point is that yarn is isolated part from the feeding bobbin.Be cyclically-varying owing to extend to the drift of the yarn F of the terminal ring that rotates guide arm 23 from feeding bobbin towing point, and, from this ring, yarn is replaced substantially invariable speed and is pulled, and the pulse of described drift causes being applied to the angle draw speed on the yarn and the pulse of hauling speed by guide arm 23.Corresponding to reel for yarn around towing point, yarn F is on the reversal point of feeding bobbin 11 unwindings, unwinding guide arm 23 has one jiao of acceleration.Unwinding device 20 has certain inertia ratio to its weight and structure, and by being drawn upward and the yarn driven rotary of unwinding from the feeding bobbin 11.When lead the feeding bobbin the top inverse change time, the unwinding resistance of yarn F increases suddenly, and it is big that the angle of displacement between guide arm 23 and the yarn towing point becomes: unwinding device 20 exceeds the yarn towing point, because becoming, angular displacement causes a positive peak tension greatly, have to a certain degree subsequently and loosen, the peak tension of " bearing " also promptly occurs.On the other hand, when lead the feeding bobbin the top inverse change time, yarn F unwinding resistance force diminishes, angular displacement between yarn F towing point and the guide arm 23 diminishes: unwinding device 20 has certain inertia, adjust to some extent immediately, and in transmission course, because the tension force that diminishes of angular displacement has loosening to a certain degree.In other words, to be subjected to resistance big more when yarn, tight by Zhang Deyue, and angular displacement also becomes big.The yarn line segment of yarn F between towing point and ring is long more, and the frictional force that yarn is subjected to is big more.When yarn line segment shortens, the resistance that is subjected to is more little, and situation is then opposite.
In the exit of the top of unwinding device 20 transmitter 21, yarn F is redirected to the below, forms the air ring B of internal layer.To end, in the process of transmitter 21, the process of time and instantaneous tension force changes to be represented with the solid line TI among Fig. 3 above yarn is redirected to from the initiating terminal of feeding bobbin 11, and the yarn mean tension is expressed as dotted line TM.Begin to end from process, instantaneous tension force presents irregular pulse phenomenon, and mean tension increases gradually.So whole tension force is pressure and the resistance sum that provides until the whole kinematic system of the inlet of radial passage 28 on the yarn and from the towing point.
Different with outer air ring B ', internal layer air ring B reason not enough owing to the space and system geometries does not have compensating sheave.For these reasons, the yarn among the internal layer air ring B has a pulse tension force naturally, and this tension force makes air ring itself present unstability.Based on this, the shape of internal layer air ring B and size continue to change.The tension force of internal layer air ring B can not too greatly can not be too little.Cross low tension force and make two air ring B and B ' interfere with each other, yet maximum danger is excessive tension force.Crossing hightension and will reduce around the coiling of the reservation of second air ring B ' of surperficial 36 among the decline air ring B makes during it plays pendulum.Thisly cross the diameter dimension that hightension also reduces internal layer air ring B simultaneously, make and air ring rotation and contact at a high speed itself cause broken yarn with the periphery of the Sheng yarn jar of fixing 10.When both contacted, yarn was attached to also being reeled in the above on the ladle bowl, and the result is torn immediately.
Summary of the invention
The present invention proposes a kind of new unwinding apparatus that is used for fourfold twist spindle, and this unwinding apparatus can be controlled internal layer air ring B and regulate the tension value of yarn, and can overcome above-mentioned defective of the prior art.In the present invention, the prevailing meaning by the employed unwinding apparatus of twisting machine is limited by first claim.Its advantageous variant and embodiment are limited by dependent claims 2-5.

For the operation of giving compensator 51 leaves activity space, in the specific embodiment in Fig. 4, the tension element 25 of folded yarn is placed in the bottom of axial cavity 24.Fig. 4 amplifier section more clearly illustrates, tension element is made up of the elastic piston 26 with spring, this spring is positioned at the inside of elastic piston, elastic piston is pressed against the F of twine on the annular deflection seat 27 of bottom with its upper end, and the horizontal guide arm 59 of the bottom of piston 26 and L shaped bar 52 leans.In this embodiment, when yarn F had been tensioned, the tension force that tensioner 25 applies was just less, and when yarn F was lax, the tension force that tensioner applies was just bigger.
Fig. 3 is illustrated in the unwinding process of feeding bobbin 11, a pulse process of unwinding tension.When tension force becomes big, yarn F is easy to the guide arm 55 of pulley 56 and bar 52 is taken on the axis of axial cavity 24, and yarn travel shortens and the compensation yarn tension.Bar 52 rotates along clockwise direction.The other end 60 of bar 52 is tending towards being lowered and is used for extrusion spring 62, and piston 61 is shortened.In addition, the circle segment that is resisted against on the ceramics seat 27 of yarn F diminishes.
When yarn F tension force discharges, spring 62 stretches and elastic piston 61 is prolonged: the other end 60 of bar rises, bar 52 is tending towards mobile pulley 56 and guide arm 55 axis away from axial cavity 24 along rotation counterclockwise, prolongs the stroke of yarn and compensates the tension force of yarn.When tension force discharged, the yarn F length that holds ceramics seat 27 increased.Therefore compensation arrangement 51 has realized that also Fig. 1 and Fig. 2 plant the function of tension element 25.
