Above-mentioned flier 38 forms towards above-mentioned yarn and stockpiles the shape that the outer peripheral face 21a of roller 21 is suitably crooked, can engage (hook spins 10) with spinning 10.Stockpile at yarn under the state of the yarn of not reeling on the roller 21, when flier 38 and yarn stockpiled roller 21 one positive rotation, flier 38 engaged with spinning 10.So the spinning 10 that has engaged with the flier 38 of this rotation is waved by this flier 38, the yarn that is directed to positive rotation stockpiles on the outer peripheral face of roller 21 and is reeled.
As shown in Figure 5, when spinning 10 is winding to yarn when stockpiling on the outer peripheral face of roller 21, spinning 10 and yarn stockpile that frictional force works between the roller 21.Therefore, if in this state yarn stockpile roller 21 with certain speed (the 1st rotary speed) along the 1st direction positive rotation, then stockpile the power that roller 21 produces drawing-off upstream sides spinning 10 by this yarn, can from spinning apparatus 9, pull out spinning 10 with certain speed.
Illustrate that then the yarn that is wound up into positive rotation stockpiles the appearance of the spinning 10 on the roller 21.The butt one that is stockpiled roller 21 through the spinning 10 of upstream side thread-carrier 23 from yarn is side directed to outer peripheral face 21a, and multi-turn is wound on the cylindrical portion 21c.Be winding to the spinning 10 on the cylindrical portion 21c because yarn stockpiles the positive rotation of roller 21 will spin and 10 be wound up into butt one side again, so butt one side that stockpiles roller 21 from yarn gradually is sent to top one side.And the spinning 10 that goes out from top one layback of outer peripheral face 21a is being sent to the downstream through behind the flier 38 through downstream thread-carrier 26.
And, stockpile under the state that is wound with spinning 10 on the roller 21 at yarn as shown in Figure 5, if apply the power that the spinning 10 that will engage with flier 38 is stretched to downstream one side, then make repiece parts 22 rotation 10 power that stockpile from yarn under the top one side unwinding of roller 21 of will spinning in effect on the flier 38.Therefore, if it is big to the degree that overcomes the above-mentioned moment of resistance that yarn stockpiles the yarn tension (yarn stockpiles the yarn tension between device 12 and the coiler device 13) of device 12 downstreams one side, then repiece parts 22 stockpile roller 21 rotation independently mutually with yarn, thus, spinning 10 is got off from top that yarn stockpiles roller 21 by unwinding gradually through fliers 38.
Otherwise the yarn tension that stockpiles device 12 downstreams one side at yarn does not have big to the situation of the degree that overcomes the above-mentioned moment of resistance under, and repiece parts 22 stockpile roller 21 one with yarn and rotate.At this moment, the repiece parts 22 top one side unwinding that stops the yarn of spinning 10 from rotation to stockpile roller 21 is worked with getting off.
So, yarn stockpiles device 12 and moves like this, when increasing, the tension force of downstream spinning 10 stockpiles on the roller 21 the unwinding spinning 10 of getting off from yarn, stoping spinning 10 to stockpile on the roller 21 unwinding from yarn when spinning 10 tension force reduces (spinning 10 becomes slack) gets off, thus, can eliminate the lax of spinning 10 gives suitable tension force for spinning 10.
Yarn stockpiles device 12 and also eliminate the lax of spinning 10 in the process of joint action.That is, in the joint course of action,, still send spinning 10 continuously during this from spinning apparatus 9 though the coiling action of coiler device 13 stops.Therefore, if like this no matter spinning 10, then spin 10 just produced lax.Here by make spinning 10 be wound up into yarn stockpile prevent from the roller 21 to spin 10 lax.
And, as mentioned above, so that absorb and stockpile the tension change of device 12 to the spinning 10 the coiler device 13 from yarn, 10 the tension change of can preventing to spin has influence on the spinning 10 that stockpiles from spinning apparatus 9 to yarn the device 12 by making repiece parts 22 action.Stockpile device 12 by the yarn that adopts said structure, can pull out spinning 10 from spinning apparatus 9 with more stable speed.
The fine spining machine 1 that this example then is described stockpile than yarn device 12 by downstream one side generation broken yarn etc., need remove and be wound up under the situation that yarn stockpiles the spinning 10 on the roller 21 control that cell controller 60 is carried out.This control comprises the 1st control, the 2nd control and the 3rd control.In addition, in the following description, will begin yarn sometimes from the predetermined moment and stockpile the number of turns that roller 21 rotated and abbreviate " rotation amount " as.
At first broken yarn etc. takes place and carry out control before the 1st control with reference to detecting in a succession of control that Fig. 6, Fig. 7 and Fig. 8 instruction book cell controller 60 carried out.Fig. 6 is the flow chart of the detection and the 1st control of explanation broken yarn etc.The stereogram of the appearance when Fig. 7 stockpiles roller 21 with the contrary rotation of the 1st speed for the expression yarn.The stereogram of the appearance when Fig. 8 is about to begin with the contrary rotation of the 2nd speed for the expression yarn stockpiles roller 21.
Downstream one side (yarn stockpiles between device 12 and the coiler device 13) that yarn stockpiles device 12 in the spinning operation process has taken place under the situation that broken yarn or splicer 43 joints fail, and coiler device 13 can not be given tension force to the spinning 10 that yarn stockpiles on the roller 21.Therefore, can not stockpile roller 21 a side unwinding downstream spinning 10 from yarn.
This speciogenesis broken yarn and joint failure detect with following yarn sensor 31.That is, yarn sensor 31 does not detect spinning 10 o'clock at preset time (for example about 1 second) instantly, and cell controller 60 is judged to be to stockpile between device 12 and the coiler device 13 at yarn broken yarn takes place, and can not proceed winding work (step S101).Be judged to be under the situation that broken yarn etc. has taken place at cell controller 60, stop the drawing-off action of drafting system 7 and the spinning action of spinning apparatus 9 etc. immediately, cut off spinning 10 (step S102).
And cell controller 60 still makes yarn stockpile roller 21 after cutting off spinning 10 to continue positive rotation (to the rotation of the 1st direction), thus, will be because spinning apparatus 9 grades stop cut yarn end be wound up into yarn and stockpile on the roller 21.After this, transfer to the 1st control (step S103).
In the 1st control, cell controller 60 by make motor 25 stop positive rotation, then to reverse rotational direction (the 2nd direction) drive motor 25, make yarn stockpile the contrary rotation of roller 21 (step S104) thus.Yarn stockpiles the contrary rotation of roller 21 to carry out with the 1st lower speed (the 1st rotary speed).
Stockpile at yarn near butt one side of roller 21, dispose the attraction mouth 30b of suction device 30, in attracting mouthful 30b, produce attraction stream.For butt one side that stockpiles roller 21 from yarn when being wound up into yarn and stockpiling on the roller 21 begins to reel, 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 the yarn end was not attracted mouthful 30b and attracted this moment, also because above-mentioned the 1st speed is lower speed, the yarn end rotates along radial direction in butt one side that yarn stockpiles roller 21 lentamente.Therefore, the yarn end almost is subjected to attracting the effect of flowing to be inhaled into attracting among mouthful 30b in all cases.In addition, the yarn end is illustrated among Fig. 7 in the appearance that is about to be inhaled into before attracting among mouthful 30b.
Because butt one side that spinning 10 stockpiles roller 21 from this yarn when make yarn stockpile roller 21 positive rotation begins to reel, if therefore make yarn stockpile roller 21 contrary rotations (rotating to the 2nd direction), 10 butt one sides that stockpile roller 21 from this yarn of then spinning begin unwinding.Make yarn stockpile roller 21 contrary rotations under mouthful state of 30b attraction by being attracted at the yarn end as described above, stockpile the spinning 10 that stockpiles on the roller 21 at this yarn and stockpile from this yarn gradually under the butt one side unwinding of roller 21.Spinning 10 stockpiles on the roller 21 under the unwinding from yarn when, remain in the spinning 10 that yarn stockpiles on the roller 21 and be attracted to successively in the suction device 30.
As mentioned above, stockpiling on the relative position of butt one side of roller 21, disposing and stockpile quantity sensor 27 (not expression among Fig. 7) with yarn.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 ").
Following mask body describes.Owing to being wound up into yarn at detection position P1 place, spinning 10 stockpiles on the roller 21 among Fig. 7, therefore from stockpiling quantity sensor 27 toward the cell controllers 60 output amount of stockpiling detection signals.On the other hand, when the butt one side unwinding that stockpiles roller 21 from yarn spinning 10, as during by unwinding, not carrying the amount of stockpiling detection signals toward cell controllers 60 in the spinning 10 of detection position P1 as shown in Figure 8 from stockpiling quantity sensor 27.If not when stockpiling the quantity sensor 27 output amount of stockpiling detection signals, cell controller 60 is judged to be spinning 10 and stockpiles on the roller 21 unwinding from yarn and get off successfully, thereby transfers to the 2nd control.And, make yarn stockpile roller 21 contrary rotation front and back, spinning 10 might be wrapped in yarn and stockpile on flier 38 grades of roller 21, has represented this appearance among Fig. 8.
In addition, in above-mentioned the 1st control, when transfer to rotation amount that the 1st control back yarn stockpiles roller 21 reached predetermined when severals or transfer to the 1st control after through during preset time, then be judged to be spinning 10 and do not stockpile unwinding on the roller 21 (spinning 10 does not attracted to and attracts a mouthful 30b) from stockpiling the quantity sensor 27 output amount of stockpiling detection signals if continue from yarn.At this moment, cell controller 60 stops the driving of motor 25, makes yarn stockpile roller 21 stop the rotation (step S106).
Then the 2nd control is described with reference to Fig. 9 and Figure 10.Fig. 9 is the flow chart of explanation the 2nd control.Figure 10 stockpiles the stereogram of roller 21 with the appearance of the contrary rotation of the 3rd speed for the expression yarn.
When transferring to for the 2nd when control, cell controller 60 improves the rotary speed of motor 25, makes yarn stockpile roller 21 with than the contrary rotation of the 1st fast the 2nd speed (the 2nd rotary speed) (step S107).Remain in yarn and stockpile spinning 10 on the roller 21 and stockpile on the roller 21 unwinding from yarn at a high speed and get off by making yarn stockpile the contrary at a high speed rotation of roller 21 like this, can making thus.Therefore, the 2nd rotary speed is set in and utilizes centrifugal force to make yarn stockpile the speed of the degree that the spinning 10 on the roller 21 hikes up.
Also will flow to cell controller 60 (being output as " ON ") (step S108) from the amount of the stockpiling detection signal that stockpiles quantity sensor 27 in the 2nd control from stockpiling quantity sensor 27 always.If remain on " OFF " from the output that stockpiles quantity sensor 27, cell controller 60 is not controlled especially.But, become " ON " (step S108, step S111, step S114) if stockpile the output of quantity sensor 27, then be judged to be and stockpile unwinding is got off on the roller 21 spinning 10 from yarn and be wound up into yarn again and stockpile on the roller 21, stop the contrary rotation that yarn stockpiles roller 21.In addition, to be wound up into once more that yarn stockpiles on the roller 21 be along carrying out with just often opposite direction (i.e. one side direction butt, one side from the top) in spinning 10.
Cell controller 60 meterings make yarn stockpile roller 21 stockpiles roller 21 with the contrary rotation of the 2nd speed back yarn rotation amount and time (step S109).When the yarn of cell controller 60 metering stockpiles the rotation amount of roller 21 or time that yarn stockpiles the contrary rotation of roller when surpassing predetermined value, cell controller 60 improves the speed of motor 25 rotations, makes yarn stockpile roller 21 with than the contrary rotation of the 2nd fast the 3rd speed (step S110).
By making yarn stockpile roller 21 temporarily with the 3rd speed rotation, 10 be wound on the flier 38 even spin, also can be as utilizing centrifugal force to shake off the spinning 10 of winding as shown in Figure 10.
It is a lot of soon that the 3rd speed is attracted the speed that device 30 attracts than spinning 10, if continue to stockpile unwinding spinning 10 on the roller 21 from yarn 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 stockpile roller 21 near.At this moment, spinning 10 just is wound into yarn and stockpiles roller 21 each place on every side.Therefore, stockpiling the rotation amount or the time set of roller 21 with the 3rd speed drive yarn must be shorter.Making yarn stockpile roller 21 contrary rotation back yarns with the 3rd speed stockpiles the rotation amount of roller or measures (step S112) against rotational time is the same with step S109 by cell controller 60.When yarn stockpiled the rotation amount of roller 21 or contrary rotational time and surpasses predetermined value, the driving of cell controller 60 control motor 25 made yarn stockpile roller 21 contrary rotations (step S113) with the 2nd speed once more.
Cell controller 60 makes yarn stockpile roller 21 with the contrary rotation of the 2nd speed as described above (the 2nd time), till making yarn stockpile roller 21 contrary postrotational rotation amounts or contrary rotational time to surpass predetermined value with the 2nd speed, transfers to the 3rd control then.Stockpile the rotation amount of roller 21 or against rotational time also with step S109 with step S112 the same with cell controller 60 measure (step S115) for yarn this moment.
In addition, rotation amount or the contrary rotational time that makes yarn stockpile roller 21 contrary rotations in the 2nd control automatically obtained according to the condition of setting by cell controller 60.Can consider that for example following method is as the method for obtaining.
That is, pre-estimate and remain in the imagination maximum that yarn stockpiles the length of the spinning 10 on the roller 21.In addition, be wound on yarn generally speaking and stockpile moment of length maximum of the spinning 10 on the roller 21 for just finishing the post-job moment of joint.Reason be as described above in the joint operation process yarn stockpile roller 21 to positive direction rotation, continue the spinning 10 of reeling and coming over from upstream row.On the other hand, because the downstream that does not have past yarn to stockpile roller 21 in the joint operation process provides spinning 10, therefore in the time of joint operation (being the time about 1 second in this example), provide the spinning 10 that comes to be trapped in yarn and stockpile on the roller 21 from spinning apparatus 9.
And, as mentioned above, after broken yarn etc. takes place, judge before and do not produced broken yarn etc. to passing through preset time (for example about 1 second).Therefore can think that providing the spinning 10 that comes further to be winding to yarn from spinning apparatus 9 stockpiles on the roller 21 in this scheduled time.
And the speed of spinning is preestablished, the required time of joint operation and can be set too to the time of judging before the broken yarn.Therefore, can obtain the imagination maximum of spinning 10 length by spinning speed being multiply by above-mentioned time sum.Cell controller 60 determine for yarn stockpile roller 21 rotary speed and, even the predetermined value of rotation amount and rotational time so that make is wound up into length that yarn stockpiles the spinning 10 on the roller 21 and is the 10 also unwindings fully of spinning of this maximum.
Below with reference to Figure 11~Figure 13 the 3rd control is described.Figure 11 is the flow chart of explanation the 3rd control.Figure 12 captures the longitudinal section of the appearance of yarn and following yarn for expression utilizes suction pipe 44 and suction nozzle 46.The longitudinal section of the appearance when Figure 13 represents to go up yarn and following yarn and is directed in the splicer 43.
In the stage that the 2nd control finishes, being wound up into the spinning 10 that yarn stockpiles on the roller 21 should all be removed.But, do not stockpiled roller 21 during with the contrary rotation of the 3rd speed and still might be hung on flier 38 grades except that clean spinning 10 from yarn.Therefore, for such spinning 10 is shaken off from flier 38 grades, cell controller 60 makes yarn stockpile roller 21 positive rotation (step S116).
The positive rotation that yarn stockpiles roller 21 lasts till with this speed makes rotation amount after its positive rotation or time surpass (step S117) till the predetermined value.This predetermined value is set smallerly.Cell controller 60 transmits control signal for joint chassis 3, makes joint chassis 3 this spinning unit 2 fronts of walking, beginning joint action (step S118).At first, cell controller 60 makes suction nozzle 46 turn to the near surface (with reference to Figure 12) of package 45, makes the stream effect that attracts in the attraction mouth of suction nozzle 46, makes package 45 contrary rotations by coiler device 13 simultaneously.Thus, draw yarn discharging end (following yarn), attract and catch by suction nozzle 46 from the outer peripheral face of package 45.
Then, cell controller 60 usefulness coiler devices 13 make the contrary rotation of package 45, under suction nozzle 46 is attracting descend the state of yarn suction nozzle 46 are upwards rotated simultaneously, and this time yarn is guided to splicer 43 (with reference to Figure 13).When yarn is directed in the 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.Cell controller 60 drives spinning apparatus 9 grades once more and restarts spinning, makes simultaneously to attract miscarriage to catch the yarn end of spinning apparatus 9 one sides (going up yarn) from birth in suction pipe 44.Then, while continue to attract to rotate suction pipe 44, also will spin 10 guiding to splicer 43 (with reference to Figure 13) by pulling out spinning 10 from spinning apparatus 9 like this.
When the joint operation of carrying out when splicer 43 was finished, coiler device 13 restarted normal winding work.
Mistake as described above like that, the fine spining machine 1 of this example has yarn and stockpiles roller 21, motor 25 and cell controller 60.Yarn stockpiles roller 21 by being wound up on the outer peripheral face by the spinning 10 that spinning apparatus 9 generates and rotation, temporarily stockpiles spinning 10.Motor 25 drives yarn and stockpiles roller 21 rotations.Need under the situation of unwinding being wound up into the spinning 10 that yarn stockpiles on the roller 21, cell controller 60 makes yarn stockpile roller 21 contrary the 1st controls of controlling motor 25 rotatably.Then, cell controller 60 makes yarn stockpile roller 21 with contrary the 2nd control of controlling motor 25 rotatably of the speed higher than the rotary speed in the 1st control.Cell controller 60 temporarily increases the control that yarn stockpiles the contrary rotary speed of roller 21 in the 2nd control.
Thus, even yarn is stockpiled under roller 21 contrary rotation front and back spinning 10 situations about being wrapped on flier 38 grades, become the 3rd speed, temporarily increase the speed that yarn stockpiles roller 21 contrary rotations by the speed that makes yarn stockpile roller 21 contrary rotations, the enough centrifugal force of energy etc. shakes off to be wrapped in the yarn on flier 38 grades.Therefore, needn't operator's manual working remove the spinning 10 of winding, can efficient carry out the spinning operation of fine spining machine 1 well.
Cell controller 60 makes yarn stockpile the 3rd control of roller 21 positive rotation ground control motor 25 after the 2nd control in the fine spining machine 1 of this example.Thus, stockpile roller 21 along 10 o'clock directions of the spinning rotation of reeling, can stockpile roller 21 grades from yarn and shake off and when yarn stockpiles roller 21 contrary rotations, do not remove clean spinning 10 by making yarn.Therefore, needn't operator's manual working remove yarn and stockpile unwanted spinning 10 around the roller 21, can efficient carry out the spinning operation of fine spining machine 1 well.
In the fine spining machine 1 of this example, cell controller 60 changes rotary speed, the yarn that the yarn in the 2nd control stockpiles roller 21 according to spinning speed and stockpiles the rotation amount of roller 21 and the rotational time that yarn stockpiles roller 21.Thus, need not make yarn stockpile the undue rotation of roller 21 and just can stockpile spinning 10 unwindings on the roller 21 being wound on yarn.
The fine spining machine 1 of this example have detect stockpile yarn to stockpile spinning 10 on the roller 21 be more than scheduled volume or not enough scheduled volume stockpile quantity sensor 27.Thus, removing when remaining in yarn and stockpiling spinning 10 on the roller 21, can detect this spinning 10 and more than a certain amount of, change to not enough a certain amount of situation.Whether as a result, can be enough stockpile quantity sensor 27 detects and can stockpile roller 21 contrary rotations by yarn and will be wound up into yarn and stockpile spinning 10 unwindings on the roller 21.And,, stockpile quantity sensor 27 and stockpile the amount of stockpiling that stockpiles the spinning 10 on the roller 21 at yarn during operation in spinning by detection, can stockpile amount of thread on the roller 21 and control and remain on suitable amount being trapped in yarn.
In the fine spining machine 1 of this example, detect and stockpile when yarn stockpiles spinning 10 not enough scheduled volumes on the roller 21 when stockpiling quantity sensor, cell controller 60 is transferred to the 2nd control from the 1st control.Thus, detect and be wound on after yarn stockpiles spinning 10 beginning unwindings on the roller 21 from stockpiling quantity sensor 27, the rotary speed that cell controller 60 can enough the 2nd control make yarn stockpile roller 21 increases.Therefore, can prevent to stockpile from yarn that the kaput state yarn under working of unwinding stockpiles roller 21 rotation at a high speed on the roller 21, make this spinning 10 be wound into each place in spinning 10.Therefore, can reduce the 10 needed times of spinning of handling winding significantly.
In the fine spining machine 1 of this example, in the 2nd control, detect to stockpile and stockpile spinning 10 on the roller 21 when scheduled volume is above when stockpiling quantity sensor 27 at yarn, cell controller 60 makes yarn stockpile roller 21 to stop the rotation.Thus, stockpile under the situation on the roller 21 even be wound up into yarn in the other direction in the influences that spinning 10 is subjected to yarn to stockpile the contrary rotation of roller 21, also can enoughly stockpile quantity sensor 27 and detect this state, cell controller 60 can make yarn stockpile roller 21 to stop the rotation immediately.Therefore, 10 the influences when yarn stockpiles roller 21 unwindings and failed that can reduce to spin, can prevent from for example to spin 10 is wound up into yarn in a large number and stockpiles on the roller 21.
In the fine spining machine 1 of this example, even yarn stockpiles the rotation amount of roller 21 or rotational time surpasses predetermined value in the 1st control, when stockpile quantity sensor 27 do not detect stockpile yarn stockpile on the roller 21 spinning 10 not enough scheduled volumes (in other words, stockpile quantity sensor 27 continue to detect to stockpile at yarn stockpile spinning 10 on the roller 21 more than scheduled volume) time, cell controller 60 makes yarn stockpile roller 21 to stop the rotation.Thus, can be enough stockpile quantity sensor 27 and detect spinning 10 and do not stockpile roller 21 from yarn and begin unwinding, cell controller 60 can make yarn stockpile roller 21 to stop the rotation.Therefore, can prevent to spin 10 for a long time yarn stockpile roller 21 around rotation, can reduce spinning 10 possibilities that are wound on flier 38 grades.
The fine spining machine 1 of this example possesses and can stockpile among near roller 21 outer peripheral faces the attraction mouth 30b and produce the suction device 30 that attracts stream being disposed at yarn.Thus, when being wrapped in yarn when stockpiling spinning 10 on the roller 21 by unwinding, can remove this unwinding immediately spinning 10.Therefore, can prevent that the spinning 10 of untiing is wound into yarn once more and stockpiles on the roller 21.
Preferred example of the present invention more than has been described, but said structure can for example change as follows.
Though the speed of using the 2nd speed and this two-stage of the 3rd speed to change in the 2nd control stockpiles the contrary rotary speed of roller 21 as yarn, but so long as make yarn stockpile roller 21 temporarily with the contrary rotation of high speed, the speed that makes its variation also can be for example 3 grades, change more than 4 grades.And also be arbitrarily the opportunity that temporarily makes yarn stockpile the rotation high speed of roller 21.
Also can have respectively and carry out the structure that the joint operation uses and replace the structure of carrying out the joint operation with joint chassis 3 with each spinning unit 2.
Stockpiling the method that applies torque between the roller 21 at repiece parts 22 and yarn and be not limited to above-mentioned magnetic texure, also can be for example frictional force or electromagnetic structure.
Repiece parts 22 stockpile roller 21 with yarn and also can rotate not relatively, also can make the lax notch part that forms on the roller of eliminating play repiece portion for example as the disclosed relaxation eliminating device of TOHKEMY 2004-124333 communique.
The shape of suction device 30 is not limited to above-mentioned shape.For example, also can form the structure that the structure that attracts mouth is substituted in the top formation attraction mouthful 30b of suction tube 30c with the top of cubic cartridge.
