The detailed structure of yarn accumulation device 12 is described below with reference to Fig. 4 and Fig. 5.The roller member that above-mentioned yarn accumulation roller 21 forms for the material with having ABRASION RESISTANCE.Yarn accumulation roller 21 is fixed on the motor reel 25a of motor 25.If using a side with repiece parts 22 as top, using a side of configuration motor 25 as butt, the outer peripheral face 21a of yarn accumulation roller 21 has butt side tapered portion (base-end taper portion) 21b, cylindrical portion (cylindricalportion) 21c, tip side tapered portion (tip-end taper portion) 21d successively from butt to top.
Cylindrical portion 21c forms thin a little any the shape of top one side, and be and the tapered portion 21b of both sides and 21d between there is no step, continuous shape.The above-mentioned quantity sensor 27 (not representing in Fig. 5) that stockpiles configures with this cylindrical portion 21c oppositely.Stockpile quantity sensor 27 and detect the amount of stockpiling that is wound up into the yarn on yarn accumulation roller 21, the amount of stockpiling detecting is sent to cell controller 60.Be specially, stockpile the detection position P1 shown in quantity sensor 27 watch circles 5 (chain-dotted line of Fig. 5 around scope), if P1 place, this detection position is wound with spinning 10, from stockpiling quantity sensor 27, toward the output of cell controller 60, become " ON ", the output amount of stockpiling detection signal.And if this detection position P1 do not reel spinning 10, cylindrical portion 21c exposes, from stockpiling quantity sensor 27 toward the cell controller 60 output amount of stockpiling detection signals.That is, from stockpiling quantity sensor 27, toward the output of cell controller 60, become " OFF ".
Butt side tapered portion 21b and tip side tapered portion 21d are respectively the large mild pyramidal structure of end one side diameter.On the outer peripheral face 21a of yarn accumulation roller 21, butt side tapered portion 21b adopts and makes the spinning 10 of supplying with from particle size part to small diameter part, divide swimmingly the mobile surperficial structure that arrives cylindrical portion 21c, spinning 10 is wound up in good order to cylindrical portion 21c.Tip side tapered portion 21d has the knocking over phenomenon (sloughing phenomenon) that the spinning 10 that prevents from reeling when a side unwinding spinning 10 downstream comes off quickly, divides the particle size part that is sent to successively end face side 10 functions of pulling out swimmingly of again reeling, guarantee to spin by spinning 10 from small diameter part simultaneously.
Near yarn accumulation roller 21, dispose suction device 30, suction device 30 has the suction tube 30c that forms tubulose.Suction tube 30c one distolateral be open end, form to produce attract the attraction mouth 30b of stream.Attract mouthful 30b be configured near the outer peripheral face of yarn accumulation roller 21, near the end of butt one side of this yarn accumulation roller 21.The effect of the attraction stream that suction device 30 produces is born in the spinning 10 that utilizes this structure to make to be wound up into yarn accumulation roller 21 butt one sides.In addition, this suction tube 30c is being connected with above-mentioned tube connector 30a.Thus, from attracting Soft flocks and yarn bits that mouthful 30b sucks to be removed by tube connector 30a, be finally collected in predetermined place discarded.
The driving of above-mentioned motor 25 (direction that comprises driving) and stop being controlled by cell controller 60 as shown in Figure 3.Thus, cell controller 60 can be controlled the driving of yarn accumulation roller 21 etc.In normal package coiling operation process, with certain speed (the 1st rotary speed), the direction of rotation (the 1st direction) during along normal winding drives 21 rotations of yarn accumulation roller to cell controller 60.Thus, spinning 10 is winding on yarn accumulation roller 21 with certain speed, by this spinning 10 of having reeled that stretches, from spinning apparatus 9, with certain speed, pulls out spinning 10.
In addition, in the following description, sometimes the rotation of the direction of rotation when making yarn accumulation roller 21 along normal winding is referred to as " positive rotation ", will make the rotation of yarn accumulation roller 21 contrary direction (the 2nd direction) when with normal winding referred to as " reverse rotation ".
As shown in Figure 4 and Figure 5, the repiece parts 22 that are configured in yarn accumulation roller 21 top one sides as one man configure axis and above-mentioned yarn accumulation roller 21.Repiece parts 22 have flyer shaft 33, are fixed on the flier (flyer) 38 on these flyer shaft 33 tops.
Flyer shaft 33 can be supported rotatably with respect to yarn accumulation roller 21.On the other hand, mounting permanent magnet on some in flyer shaft 33 or yarn accumulation roller 21 is installed hysteresis material on another.Utilize these magnetic texures to produce and stop repiece parts 22 with respect to the counterrotating torque of yarn accumulation roller 21.Utilize this moment of resistance that repiece parts 22 are driven in the rotation of yarn accumulation roller 21 and rotate, result can one be rotated repiece parts 22 and yarn accumulation roller 21.On the other hand, in the situation that apply the power that overcomes this moment of resistance on repiece parts 22, repiece parts 22 can relatively rotate with respect to yarn accumulation roller 21.
Above-mentioned flier 38 forms suitable crooked, the shape that can engage with spinning 10 (hook spins 10) towards the outer peripheral face 21a of above-mentioned yarn accumulation roller 21.On yarn accumulation roller 21, do not have under the state of winding yarn, when flier 38 and yarn accumulation roller 21 one positive rotation, flier 38 engages with spinning 10.So the spinning 10 having engaged with the flier 38 of this rotation is waved by this flier 38, be directed on the outer peripheral face of yarn accumulation roller 21 of positive rotation and be wound.
As shown in Figure 5, when spinning 10 is winding on the outer peripheral face of yarn accumulation roller 21, between spinning 10 and yarn accumulation roller 21, frictional force works.Therefore, if in this state yarn accumulation roller 21 with certain speed (the 1st rotary speed) along the 1st direction positive rotation, by this yarn accumulation roller 21, produce the power of drawing-off upstream side spinning 10, can from spinning apparatus 9, pull out with certain speed spinning 10.
The appearance of the spinning 10 on the yarn accumulation roller 21 that is wound up into positive rotation is then described.Spinning 10 through upstream side thread-carrier 23 is directed to outer peripheral face 21a by butt one side from yarn accumulation roller 21, and multi-turn is wound on cylindrical portion 21c.Be winding to spinning 10 on cylindrical portion 21c because the positive rotation of yarn accumulation roller 21 is wound up into butt one side again by spinning 10, therefore from butt one side of yarn accumulation roller 21, be sent to top one side gradually.And the spinning 10 going out from top one layback of outer peripheral face 21a is being sent to downstream through downstream thread-carrier 26 after flier 38.
And, on yarn accumulation roller 21, be wound with under the state of spinning 10 as shown in Figure 5, if apply the power that the spinning 10 engaging with flier 38 is stretched to downstream one side, on flier 38, effect makes repiece parts 22 rotate the power from the top one side unwinding of yarn accumulation roller 21 by spinning 10.Therefore, if the yarn tension of yarn accumulation device 12 downstream one sides (yarn tension between yarn accumulation device 12 and coiler device 13) is large to the degree that overcomes the above-mentioned moment of resistance, repiece parts 22 and yarn accumulation roller 21 rotate mutually independently, thus, spinning 10 is got off from the top of yarn accumulation roller 21 by unwinding gradually through fliers 38.
Otherwise in the situation that the yarn tension of yarn accumulation device 12 downstream one sides does not have is large to the degree that overcomes the above-mentioned moment of resistance, repiece parts 22 rotate with yarn accumulation roller 21 one.Now, repiece parts 22 stop the top one side unwinding of the yarn accumulation roller 21 of spinning 10 from rotation to get off to work.
So, yarn accumulation device 12 moves like this, when the tension force of downstream spinning 10 increases, from yarn accumulation roller 21, unwinding gets off to spin 10, when reducing (spinning 10 becomes slack), the tension force of spinning 10 stop spinning 10 unwinding from yarn accumulation roller 21 to be got off, thus, can eliminate relaxing of spinning 10 and give suitable tension force to spinning 10.
Yarn accumulation device 12 is also eliminated the lax of spinning 10 in the process of joint action.That is,, in joint course of action, although the coiling action of coiler device 13 stops, during this, still from spinning apparatus 9, send continuously spinning 10.Therefore, if like this no matter spinning 10, spin 10 just produced lax.Here by make to spin 10 be wound up on yarn accumulation roller 21, prevent from spinning 10 lax.
And, as mentioned above, by making repiece parts 22 action to absorb the tension change from yarn accumulation device 12 to the spinning 10 coiler device 13,10 the tension change of can preventing from spinning has influence on from spinning apparatus 9 to the spinning 10 yarn accumulation device 12.By adopting the yarn accumulation device 12 of said structure, can from spinning apparatus 9, pull out spinning 10 with more stable speed.
The fine spining machine 1 of this example is then described in the situation that swim on the lower side generation broken yarn etc., need to remove the spinning 10 being wound up on yarn accumulation roller 21, the control that cell controller 60 carries out than yarn accumulation device 12.This control comprises that the 1st control, the 2nd is controlled and the 3rd control.In addition, in the following description, sometimes started to the number of turns that yarn accumulation roller 21 rotated the moment from predetermined referred to as " rotation amount ".
First in a succession of control of carrying out with reference to Fig. 6, Fig. 7 and Fig. 8 instruction book cell controller 60, detect and broken yarn etc. occurs and carry out the 1st control before controlling.The detection that Fig. 6 is explanation broken yarn etc. and the 1st flow chart of controlling.Fig. 7 is the stereogram of the appearance while representing yarn accumulation roller 21 with the 1st speed reverse rotation.The stereogram of appearance when Fig. 8 is about to start with the 2nd speed reverse rotation for expression yarn accumulation roller 21.
In the situation that broken yarn or splicer 43 joint failures have occurred downstream one side (between yarn accumulation device 12 and coiler device 13) of yarn accumulation device 12 in spinning operation process, coiler device 13 gives tension force can not to the spinning 10 on yarn accumulation roller 21.Therefore, can not be from a yarn accumulation roller 21 side unwinding spinning 10 downstream.
This speciogenesis broken yarn and joint unsuccessfully use lower yarn sensor 31 to detect.; instantly yarn sensor 31 for example, does not detect spinning 10 o'clock in predetermined time (about 1 second); cell controller 60 is judged to be between yarn accumulation device 12 and coiler device 13 broken yarn occurs, the operation (step S101) of can not proceeding to reel.At cell controller 60, be judged to be there is broken yarn etc. in the situation that, stop immediately the drawing-off action of drafting system 7 and the spinning action of spinning apparatus 9 etc., cut off spinning 10 (step S102).
And cell controller 60 still makes yarn accumulation roller 21 continue positive rotation (to the 1st direction rotation) after cutting off spinning 10, thus, will because spinning apparatus 9 grades stop, cut yarn end be wound up on yarn accumulation roller 21.After this, transfer to the 1st and control (step S103).
In the 1st controls, cell controller 60 by make motor 25 stop positive rotation, then to reverse rotational direction (the 2nd direction) drive motor 25, make thus yarn accumulation roller 21 reverse rotations (step S104).The reverse rotation of yarn accumulation roller 21 is carried out with the 1st lower speed (the 1st rotary speed).
Near butt one side of yarn accumulation roller 21, dispose the attraction mouth 30b of suction device 30, in attracting mouthful 30b, produce and attract stream.Butt one side from yarn accumulation roller 21 on being wound up into yarn accumulation roller 21 time starts to reel, and the yarn end that stops cut spinning 10 because of the weaving action of spinning apparatus 9 etc. is attracted mouthful 30b and attracts.Even if now yarn end is not attracted a mouthful 30b attraction, also, because above-mentioned the 1st speed is lower speed, yarn end rotates along radial direction in butt one side of yarn accumulation roller 21 lentamente.Therefore, yarn end is almost subject to attracting the effect of stream to be inhaled in attraction mouthful 30b in all cases.In addition, yarn end be about to be inhaled into attract mouthful 30b in before appearance be illustrated in Fig. 7.
Because 10 butt one sides from this yarn accumulation roller 21 of spinning when making yarn accumulation roller 21 positive rotation start to reel, therefore, if make yarn accumulation roller 21 reverse rotations (to the 2nd direction rotation), spinning 10 starts unwinding from butt one side of this yarn accumulation roller 21.By being attracted under the state that mouthful 30b attracts and making yarn accumulation roller 21 reverse rotations at yarn end as described above, stockpile spinning 10 on this yarn accumulation roller 21 gradually from the butt one side unwinding of this yarn accumulation roller 21.Spinning 10 from yarn accumulation roller 21 under unwinding in, the spinning 10 remaining on yarn accumulation roller 21 is attracted in suction device 30 successively.
As mentioned above, on the relative position of butt one side with yarn accumulation roller 21, dispose and stockpile quantity sensor 27 (not representing in Fig. 7).Cell controller 60 is controlled (step S105) according to having or not from the amount of the stockpiling detection signal that stockpiles quantity sensor 27 (output is " ON " or " OFF ").
Lower mask body describes.In Fig. 7, because spinning 10 is wound up on yarn accumulation roller 21 at P1 place, detection position, therefore from stockpiling quantity sensor 27, toward cell controller 60, export the amount of stockpiling detection signals.On the other hand, when the butt one side unwinding spinning 10 from yarn accumulation roller 21, in the spinning 10 of detection position P1, during by unwinding, from stockpiling quantity sensor 27, toward cell controller 60, do not carry the amount of stockpiling detection signals as shown in FIG. 8.If not when stockpiling the quantity sensor 27 output amount of stockpiling detection signal, cell controller 60 is judged to be spinning 10 unwinding from yarn accumulation roller 21 and gets off successfully, controls thereby transfer to the 2nd.And, making yarn accumulation roller 21 reverse rotations front and back, spinning 10 is likely wrapped in flier 38 grades of yarn accumulation roller 21, has represented this appearance in Fig. 8.
In addition, in the above-mentioned the 1st controls, when transfer to the 1st control after the rotation amount of yarn accumulation roller 21 reached predetermined when severals or after transferring to the 1st control through during predetermined time, if continued, from stockpiling the quantity sensor 27 output amount of stockpiling detection signals, be judged to be spinning 10 not unwindings from yarn accumulation roller 21 (spinning 10 does not attracted to and attracts a mouthful 30b).Now, cell controller 60 stops the driving of motor 25, makes yarn accumulation roller 21 stop the rotation (step S106).
Then with reference to Fig. 9 and Figure 10, illustrate that the 2nd controls.The flow chart that Fig. 9 controls for explanation the 2nd.Figure 10 is for representing the stereogram of yarn accumulation roller 21 appearance with the 3rd speed reverse rotation.
When transferring to the 2nd while controlling, cell controller 60 improves the rotary speed of motor 25, makes yarn accumulation roller 21 with than the 1st fast the 2nd speed (the 2nd rotary speed) reverse rotation (step S107).By making like this yarn accumulation roller 21 high speed reverse rotations, spinning 10 high speed unwindings from yarn accumulation roller 21 that can make thus to remain on yarn accumulation roller 21 are got off.Therefore, the 2nd rotary speed is set in the speed of utilizing centrifugal force to make the degree that the spinning 10 on yarn accumulation roller 21 hikes up.
In the 2nd control, also the amount of the stockpiling detection signal from stockpiling quantity sensor 27 is flowed to cell controller 60 (being output as " ON " from stockpiling quantity sensor 27) (step S108) always.If remain on " OFF " from the output that stockpiles quantity sensor 27, cell controller 60 is not controlled especially.But, if stockpile the output of quantity sensor 27, become " ON " (step S108, step S111, step S114), be judged to be the spinning 10 that unwinding is got off from yarn accumulation roller 21 and be again wound up on yarn accumulation roller 21, stop the reverse rotation of yarn accumulation roller 21.In addition, to be again wound up on yarn accumulation roller 21 be that direction (one side direction butt one side from top) along contrary when normal is carried out in spinning 10.
Rotation amount and the time (step S109) of yarn accumulation roller 21 after cell controller 60 meterings make yarn accumulation roller 21 with the 2nd speed reverse rotation.When the rotation amount of yarn accumulation roller 21 of cell controller 60 metering or the time of yarn accumulation roller reverse rotation surpass predetermined value, cell controller 60 improves the speed of motor 25 rotations, makes yarn accumulation roller 21 with than the 2nd fast the 3rd speed reverse rotation (step S110).
By yarn accumulation roller 21 is rotated with the 3rd speed temporarily, even if spinning 10 is wound on flier 38, also can utilize as shown in FIG. 10 centrifugal force to shake off the spinning 10 of winding.
It is a lot of soon that the 3rd speed is attracted than spinning 10 speed that device 30 attracts, if continue unwinding spinning 10 from yarn accumulation roller 21 with the 3rd speed, the attraction of 30 pairs of spinning 10 of suction device does not catch up with, spinning 10 be trapped in yarn accumulation roller 21 near.Now, spinning 10 is just wound into yarn accumulation roller 21 each place around.Therefore, with rotation amount or the time of the 3rd speed drive yarn accumulation roller 21, set shortlyer.With the 3rd speed make the rotation amount of yarn accumulation roller after yarn accumulation roller 21 reverse rotations or the reverse rotation time the same as with step S109 cell controller 60 meterings (step S112).When the rotation amount of yarn accumulation roller 21 or reverse rotation time surpass predetermined value, cell controller 60 is controlled the driving of motor 25, again with the 2nd speed, makes yarn accumulation roller 21 reverse rotations (step S113).
Cell controller 60 makes yarn accumulation roller 21 with the 2nd speed as described above (the 2nd time) reverse rotation, until make rotation amount or reverse rotation time after yarn accumulation roller 21 reverse rotations surpass predetermined value with the 2nd speed, then transfers to the 3rd and controls.Now for the rotation amount of yarn accumulation roller 21 or reverse rotation time, also equally with step S112 with step S109 with cell controller 60, measure (step S115).
In addition, in the 2nd control, make the rotation amount of yarn accumulation roller 21 reverse rotations or reverse rotation time automatically be obtained according to the condition of setting by cell controller 60.Can consider that for example following methods is as the method for obtaining.
That is, pre-estimate the imagination maximum of the length of the spinning 10 remaining on yarn accumulation roller 21.In addition, the moment of length maximum that is generally wound on the spinning 10 on yarn accumulation roller 21 is for just having carried out the post-job moment of joint.Reason be as described above in joint operation process yarn accumulation roller 21 to positive direction rotation, continue the spinning 10 of reeling and coming over from upstream row.On the other hand, owing to not having the downstream of past yarn accumulation roller 21 that spinning 10 is provided in joint operation process, therefore within the time of joint operation (being the time about 1 second in this example), from spinning apparatus 9, provide the spinning 10 coming to be trapped in yarn accumulation roller 21.
And, as mentioned above, after there is broken yarn etc., to passing through predetermined time (about such as 1 second), do not judge and produced broken yarn etc. before.Therefore can think and from spinning apparatus 9, provide the spinning 10 coming to be further winding to yarn accumulation roller 21 within this scheduled time.
And the speed of spinning is preset, the required time of joint operation and can being set too to the time of judging before broken yarn.Therefore, by spinning speed being multiplied by above-mentioned time sum, can obtain the imagination maximum of spinning 10 length.Cell controller 60 determine for the rotary speed of yarn accumulation roller 21 and, the predetermined value of rotation amount and rotational time is so that even the length that makes to be wound up into the spinning 10 on yarn accumulation roller 21 is the 10 also unwindings completely of spinning of this maximum.
Below with reference to Figure 11～Figure 13, illustrate that the 3rd controls.The flow chart that Figure 11 controls for explanation the 3rd.Figure 12 utilizes suction pipe 44 and suction nozzle 46 to capture the longitudinal section of the appearance of yarn and lower yarn for representing.The longitudinal section of appearance when Figure 13 represents upper yarn and lower yarn to be directed in splicer 43.
The 2nd, control the stage finishing, the spinning 10 being wound up on yarn accumulation roller 21 should all be removed.But, during with the 3rd speed reverse rotation, from yarn accumulation roller 21, do not removed clean spinning 10 and still likely hung over flier 38 grades.Therefore,, for such spinning 10 is shaken off from flier 38 grades, cell controller 60 makes yarn accumulation roller 21 positive rotation (step S116).
The positive rotation of yarn accumulation roller 21 lasts till with this speed makes rotation amount after its positive rotation or time surpass (step S117) till predetermined value.This predetermined value is set smallerly.Cell controller 60 transmits control signal to joint chassis 3, makes 3 walkings of joint chassis to these spinning unit 2 fronts, starts joint action (step S118).First, cell controller 60 makes suction nozzle 46 turn to the near surface (with reference to Figure 12) of package 45, in the attraction mouth of suction nozzle 46, makes to inhale drainage, makes package 45 reverse rotations by coiler device 13 simultaneously.Thus, from the outer peripheral face of package 45, draw yarn discharging end (yarn), by suction nozzle 46, attract and catch.
Then, cell controller 60 use coiler devices 13 make package 45 reverse rotations, simultaneously under suction nozzle 46 is attracting descend the state of yarn, suction nozzle 46 are upwards rotated, and this lower yarn is guided to splicer 43 (with reference to Figure 13).When yarn is directed in splicer 43 instantly, package 45 is stopped the rotation.
In the front and back of said suction nozzle 46 rotational action, cell controller 60 makes suction pipe 44 turn near downstream one side (with reference to Figure 12) of spinning apparatus 9.Spinning apparatus 9 grades that again drive cell controller 60 restart spinning, make the yarn end (upper yarn) that attracts miscarriage to catch from birth spinning apparatus 9 one sides simultaneously in suction pipe 44.Then,, while continue to attract to rotate suction pipe 44, by pulling out spinning 10 from spinning apparatus 9 like this, also will spin 10 guiding to splicer 43 (with reference to Figure 13).
When the joint operation of carrying out when splicer 43 completes, coiler device 13 restarts to reel normally operation.
As described above, the fine spining machine 1 of this example has yarn accumulation roller 21, motor 25 and cell controller 60.Yarn accumulation roller 21, by the spinning being generated by spinning apparatus 9 10 being wound up on outer peripheral face and rotation, temporarily stockpiles spinning 10.Motor 25 drives 21 rotations of yarn accumulation roller.In the situation that the spinning 10 being wound up on yarn accumulation roller 21 needs unwinding, cell controller 60 makes yarn accumulation roller 21 reverse rotations to be controlled the 1st of motor 25 and controls.Then, cell controller 60 make yarn accumulation roller 21 with the high speed reverse rotation of the rotary speed in controlling than the 1st control the 2nd of motor 25 and control.Cell controller 60 temporarily increases the control of the reverse rotation speed of yarn accumulation roller 21 in the 2nd controls.
Thus, even in the situation that making the 21 reverse rotations front and back spinning 10 of yarn accumulation roller be wrapped in flier 38 grades, by making the speed of yarn accumulation roller 21 reverse rotations become the 3rd speed, temporarily increasing the speed of yarn accumulation roller 21 reverse rotations, can enough centrifugal force etc. shake off to be wrapped in the yarn in flier 38 grades.Therefore, needn't operator's manual working remove the spinning 10 of winding, can efficiency carry out well the spinning operation of fine spining machine 1.
In the fine spining machine 1 of this example, cell controller 60 makes yarn accumulation roller 21 positive rotation and controls the 3rd control of motor 25 after the 2nd controls.Thus, by making yarn accumulation roller 21 along the spinning direction rotation of 10 o'clock of reeling, can shake off from yarn accumulation roller 21 grades and not remove clean spinning 10 when yarn accumulation roller 21 reverse rotation.Therefore, needn't operator's manual working remove the 21 unwanted spinning 10 around of yarn accumulation roller, can efficiency carry out well the spinning operation of fine spining machine 1.
In the fine spining machine 1 of this example, cell controller 60 changes the 2nd rotary speed of yarn accumulation roller 21 in controlling, the rotational time of the rotation amount of yarn accumulation roller 21 and yarn accumulation roller 21 according to spinning speed.Thus, too rotation just can be by spinning 10 unwindings that are wound on yarn accumulation roller 21 need not to make yarn accumulation roller 21.
The fine spining machine 1 of this example have that to detect the spinning 10 stockpile on yarn accumulation roller 21 be more than scheduled volume or not enough scheduled volume stockpile quantity sensor 27.Thus, when removing the spinning 10 remaining on yarn accumulation roller 21, can detect this spinning 10 and change to not enough a certain amount of situation more than a certain amount of.Whether as a result, can enoughly stockpile quantity sensor 27 detections can be by yarn accumulation roller 21 reverse rotations by spinning 10 unwindings that are wound up on yarn accumulation roller 21.And, in spinning, during operation, stockpile quantity sensor 27 and by detection, stockpile the amount of stockpiling of the spinning 10 on yarn accumulation roller 21, can control and remain on suitable amount being trapped in amount of thread on yarn accumulation roller 21.
In the fine spining machine 1 of this example, when stockpiling quantity sensor and the spinning 10 not enough scheduled volume stockpiling on yarn accumulation roller 21 detected, cell controller 60 is controlled from the 1st controls metastasis to the 2.Thus, from stockpiling quantity sensor 27, detect after the spinning 10 beginning unwindings that are wound on yarn accumulation roller 21, cell controller 60 can enough the 2nd control increase the rotary speed of yarn accumulation roller 21.Therefore, can prevent from stockpiling roller 21 High Rotation Speeds at spinning 10 kaput state yarn under working of unwinding from yarn accumulation roller 21, make this spinning 10 be wound into each place.Therefore, can reduce significantly and process the needed time of spinning 10 being wound around.
In the fine spining machine 1 of this example, when stockpiling quantity sensor 27, the spinning 10 that stockpiles on yarn accumulation roller 21 in the 2nd controls, detected when scheduled volume is above, cell controller 60 stops the rotation yarn accumulation roller 21.Thus, even in the situation that spinning 10 is wound up on yarn accumulation roller 21 by the impact of yarn accumulation roller 21 reverse rotations in the other direction, also can enoughly stockpiles quantity sensor 27 and this state be detected, cell controller 60 can make yarn accumulation roller 21 stop the rotation immediately.Therefore, can reduce to spin 10 from the 21 unwindings failures of yarn accumulation roller time impact, can prevent from for example spinning 10 is wound up on yarn accumulation roller 21 in a large number.
In the fine spining machine 1 of this example, even the rotation amount of yarn accumulation roller 21 or rotational time surpass predetermined value in the 1st controls, when stockpiling quantity sensor 27, the not enough scheduled volume of spinning 10 that stockpiles on yarn accumulation roller 21 do not detected (in other words, stockpile quantity sensor 27 and continue to detect the spinning 10 that stockpiles on yarn accumulation roller 21 more than scheduled volume) time, cell controller 60 stops the rotation yarn accumulation roller 21.Thus, can enoughly stockpile quantity sensor 27 and spinning 10 be detected starting unwinding from yarn accumulation roller 21, cell controller 60 can make yarn accumulation roller 21 stop the rotation.Therefore, can prevent from spinning 10 for a long time in surrounding's rotation of yarn accumulation roller 21, can reduce spinning 10 possibilities that are wound in flier 38 grades.
The fine spining machine 1 of this example possesses and can near the attraction mouth 30b being disposed at yarn accumulation roller 21 outer peripheral faces, produce the suction device 30 that attracts stream.Thus, the spinning 10 on being wrapped in yarn accumulation roller 21 is during by unwinding, can remove this unwinding immediately spinning 10.Therefore, can prevent that the spinning 10 of untiing is wound on yarn accumulation roller 21 again.
Preferred example of the present invention has more than been described, but said structure can for example change as follows.
Although use the speed of this two-stage variation of the 2nd speed and the 3rd speed as the reverse rotation speed of yarn accumulation roller 21 in the 2nd controls, but so long as make yarn accumulation roller 21 temporary transient with high speed reverse rotation, the speed that makes its variation also can be for example 3 grades, 4 grades with Shangdi, change.And temporarily making the opportunity of the rotation high speed of yarn accumulation roller 21 is also arbitrarily.
Also can have respectively and carry out the structure that joint operation uses and replace the structure of carrying out joint operation with joint chassis 3 with each spinning unit 2.
The method that applies torque between repiece parts 22 and yarn accumulation roller 21 is not limited to above-mentioned magnetic texure, can be also for example frictional force or electromagnetic structure.
Repiece parts 22 and yarn accumulation roller 21 be relative rotation not also, also can, for example as the disclosed relaxation eliminating device of TOHKEMY 2004-124333 communique, make the lax notch part forming on roller of eliminating play repiece portion.
The shape of suction device 30 is not limited to above-mentioned shape.The top that for example, also can attract the structure of mouth to be substituted in suction tube 30c with the top formation of cubic cartridge forms the structure that attracts mouth 30b.
