The detailed construction of yarn accumulation device 12 then is described with reference to Fig. 4 and Fig. 5.
Yarn accumulation roller 21 is fixed on the motor shaft 25a of motor 25 for the roller member with wear-resisting material formation.If the side that the outer peripheral face 21a of yarn accumulation roller 21 will have a repiece section 22 as the top, will dispose motor 25 a side as butt, then possess successively butt side conus portion 21b, cylindrical portion 21c and tip side conus portion 21d to the top from butt.
Cylindrical portion 21c constitutes the shape that tip side attenuates a little, and becomes the shape that does not have step ground continuous with respect to conus portion 21b and the 21d of both sides.The size of cylindrical portion 21c can stockpile at least above spinning 10 ground of the necessary minimum amount of stockpiling and suitably be set.Stockpile quantity sensor 27 possess minimum stockpile quantity detection sensor (minimum accumulated amount detecting sensor) 27a and cross stockpile detecting sensor (excessive accumulation detecting sensor) (yarn excision test section) 27b.Minimum stockpile quantity detection sensor 27a and cross stockpile detecting sensor 27b and cylindrical portion 21c arranges oppositely.
Butt side conus portion 21b and tip side conus portion 21d constitute respectively and make mild coniform for large footpath side of end face side.On the outer peripheral face 21a of yarn accumulation roller 21, part moves the middle cylindrical portion 21c of arrival to butt side conus portion 21b swimmingly from large diameter portion to path by the spinning 10 that provides is provided, and spinning 10 fitly is wound up on the surface of cylindrical portion 21c.Tip side conus portion 21d prevents when spinning 10 unwindings from yarn accumulation roller 21, the knocking over that the spinning 10 of coiling comes off quickly (sloughing phenomenon) phenomenon.Tip side conus portion 21d has and the large diameter portion of spinning 10 from path part to the end face side transmitted ground successively again reels 10 functions of pulling out swimmingly of guaranteeing to spin.
As shown in Figure 4 and Figure 5, the repiece section 22 that is configured in yarn accumulation roller 21 tops one side as one man disposes axis and yarn accumulation roller 21.Repiece section 22 possesses flyer shaft (flyer axis) 33 and is fixed on the flier 38 on flyer shaft 33 tops.
Flyer shaft 33 can supported rotatably with respect to yarn accumulation roller 21.Permanent magnet (not shown) is installed on flyer shaft 33 or yarn accumulation roller 21 some, and hysteresis material (not shown) is installed on another.Utilize these magnetic mechanisms to produce and resist repiece section 22 with respect to yarn accumulation roller 21 counterrotating moments of torsion.Utilize this resistive torque, repiece section 22 follows the rotation of yarn accumulation roller 21 and rotates, and repiece section 22 rotates integratedly with yarn accumulation roller 21 as a result.Under the power that overcomes this resistive torque was applied to situation in the repiece section 22, repiece section 22 relatively rotated with respect to yarn accumulation roller 21.
Flier 38 is suitably crooked towards the outer peripheral face 21a of yarn accumulation roller 21, constitutes the shape that can engage with spinning 10 (hook spinning 10).Under the state of the spinning 10 of not reeling on the yarn accumulation roller 21, if flier 38 and the rotation of yarn accumulation roller 21 one, flier 38 engages with spinning 10.Waved by this flier 38 with the spinning 10 that the flier 38 of rotation engages, by outer peripheral face 21a guiding and the coiling to the yarn accumulation roller 21 that rotates.
Then explanation is winding to the appearance of the spinning 10 on the yarn accumulation roller 21.The spinning 10 of having passed through upstream side thread-carrier 23 is directed on the outer peripheral face 21a by the butt side from yarn accumulation roller 21, repeatedly is wound up on the cylindrical portion 21c.The spinning 10 of pulling out from the tip side of outer peripheral face 21a is being sent to the downstream through behind the flier 38 through downstream thread-carrier 26.
Be wound with at yarn accumulation roller 21 as Fig. 5 under the state of spinning 10, move the spinning 10 that engages with flier 38 power of downstream to if pay, then want to make the power of repiece section 22 rotations to impose on flier 38 from the top ends unwinding of yarn accumulation roller 21 10 ground that spin.Therefore, if the yarn tension in yarn accumulation device 12 downstreams (yarn tension between yarn accumulation device 12 and the coiler device 13) is large to the degree that overcomes resistive torque (spinning 10 that namely engages with flier 38 is subject to the yarn tension more than the setting), then be independent of the rotation of yarn accumulation roller 21 ground by repiece section 22, spinning 10 is passed through gradually unwinding of flier 38 from the top of yarn accumulation roller 21.
Yarn tension in the downstream of yarn accumulation device 12 does not have large to the situation that overcomes resistive torque in, and repiece section 22 rotates with yarn accumulation roller 21 one.Repiece section 22 stops spinning 10 from the tip side unwinding ground action of the yarn accumulation roller 21 of rotation.
Yarn accumulation device 12 10 unwindings of will spin when the tension force of the spinning 10 in downstream increases when the tension force of yarn reduces (spinning 10 will relax), stop 10 the unwinding of spinning.Thus, yarn accumulation device 12 can be eliminated the lax of spinning 10, pays suitable tension force for spinning 10.Impose on the change ground action of the tension force of the spinning 10 between yarn accumulation device 12 and the coiler device 13 by absorbing repiece section 22, can prevent that the change of this tension force is to the spinning 12 10 brings impact from open end spinning apparatus 9 to yarn accumulation device.Can utilize yarn accumulation device 12 will spin from open end spinning apparatus 9 10 pulls out with more stable speed.
Because being winding to butt one side of this yarn accumulation roller 21, yarn accumulation roller 21 10 speed with regulation of by the speed rotary actuation with regulation, therefore spinning get on.Be wound up in the fireballing situation of butt side in the velocity ratio of spinning 10 from the tip side unwinding of yarn accumulation roller 21, the yarn accumulation amount reduces.Not in the situation of the tip side unwinding of yarn accumulation roller 21, the yarn accumulation amount increases gradually in spinning 10.
Yarn accumulation device 12 possesses yarn and extracts bar 28.Yarn is extractd the parts that bar 28 forms the approximate L font of the elongated portion (service portion (operating section) 28a) with horizontal arrangement as shown in Figure 5.The butt that yarn is extractd bar 28 is supporting with swinging axle 28b.Yarn is extractd bar 28 and can be swung along the vertical direction between lifting position (the yarn tail is extractd the position) and down position (position of readiness) centered by swinging axle 28b.When yarn excision bar 28 was positioned at down position, yarn was extractd bar 28 and is not contacted with the yarn road of spinning 10.When yarn was extractd bar 28 and is positioned at lifting position, will spin 10 yarn road of service portion 28a up pushed away, and can 10 take from flier 38 spinning.Yarn is extractd bar 28 by with the diagram abridged elastomeric element application of force, is maintained at ordinary times down position.Driven by the pneumatic cylinder 49 that joint chassis 3 possesses, yarn is extractd bar 28 and is pushed by pushing ﹠ lifting arms 47, moves to lifting position.
Move to lifting position by making yarn extract bar 28, can take spinning 10 from repiece section 22.Because the resistance (acting on the resistive torque of repiece section 22) when the tip side unwinding spinning 10 of yarn accumulation roller 21 does not act on spinning 10, therefore even in a little less than the yarn tension in the downstream of yarn accumulation roller 21, also can be from this yarn accumulation roller 21 unwindings spinning 10.Rise if under the state of the spinning 10 of not reeling on the yarn accumulation roller 21, make yarn extract bar 28, then can stop flier 38 to engage with spinning 10.As a result, spinning 10 is not wound up on the yarn accumulation roller 21 controls.
Then illustrate that with reference to Fig. 6 and Fig. 7 the yarn that is arranged in the joint chassis 3 moves the detailed of detecting sensor 50.Yarn moves the upper position that detecting sensor 50 is arranged on joint chassis 3.The detecting sensor 50 that moves yarn detects non-contactly owing to the spinning 10 that move rotatably the tip side end that centers on yarn accumulation roller 21 is rotated by repiece section 22 under spinning 10 and state that repiece section 22 engage.Yarn moves detecting sensor 50 from the lower position of yarn accumulation roller 21 towards the lid 12a irradiation laser L50 that covers yarn accumulation roller 21 sidepieces.Yarn moves the light path ground irradiation laser L50 that detecting sensor 50 makes the spinning 10 crosscut laser L50 that move rotatably around the tip side end of yarn accumulation roller 21.The laser L50 that yarn moves detecting sensor 50 irradiations is blocked in the spinning 10 of moving along the circumferencial direction of this yarn accumulation roller 21 in the tip side end of yarn accumulation roller 21 thus, off and on.Yarn moves detecting sensor 50 and detects the spinning 10 of blocking off and on laser L50.The result that the detecting sensor 50 that moves yarn detects is sent to cell controller 60.
Then stockpile the detailed of quantity sensor 27 with reference to Fig. 6 and Fig. 7 explanation.Cross and stockpile detecting sensor 27b and be arranged near the tip side end in the yarn accumulation roller 21.Cross and stockpile detecting sensor 27b towards the outer peripheral face 21a irradiation laser L27b of yarn accumulation roller 21.The irradiation position of laser L27b is got the tip side position that the spinning 10 of predetermined specific length was wound up into the outer peripheral face 21a of yarn accumulation roller 21 spinning 10 when upper from butt one side direction top one side.The spinning 10 of this predetermined specific length is the above length of the necessary minimum amount of stockpiling, the maximum length that the coiling of orientation yarn accumulation roller 21 allows.Cross and stockpile detecting sensor 27b and detect on the irradiation position of the laser L27b on the outer peripheral face 21a of yarn accumulation roller 21, whether there is spinning 10.Exist at the irradiation position of laser L27b in the situation of spinning 10, can be judged to be spinning 10 too much is wound up on the yarn accumulation roller 21, namely spinning 10 was to stockpile.
If repiece section 22 rotations under the state that spinning 10 has engaged with repiece section 22, then spinning 10 stockpiles in the space between the detecting sensor 27b mobile in the outer peripheral face 21a of yarn accumulation roller 21 and mistake.That is, by the rotation of repiece section 22, spinning 10 circumferencial direction along yarn accumulation roller 21 on the outer peripheral face 21a of yarn accumulation roller 21 moves.Blocked off and on the laser L27b that stockpiles detecting sensor 27b irradiation along the spinning 10 that the circumferencial direction of yarn accumulation roller 21 moves.Cross and stockpile the detection that detecting sensor 27b also blocks the spinning 10 of laser L27b off and on.Cross the result who stockpiles detecting sensor 27b detection and be sent to cell controller 60.
The minimum quantity detection sensor 27a that stockpiles is arranged on than excessively stockpiling on the position of detecting sensor 27b by butt one side of yarn accumulation roller 21.Minimumly stockpile quantity detection sensor 27a and cross that to stockpile detecting sensor 27b the same, towards the outer peripheral face 21a irradiation laser L27a of yarn accumulation roller 21.The irradiation position of laser L27a is got the position that the spinning 10 of the minimum amount of stockpiling of necessity was wound up into top one side of the outer peripheral face 21a of yarn accumulation roller 21 spinning 10 when upper from butt one side direction top one side.Whether there is spinning 10 on the minimum position that stockpiles the laser L27a irradiation on the outer peripheral face 21a that quantity detection sensor 27a detects yarn accumulation roller 21.Exist at the irradiation position of laser L27a in the situation of spinning 10, can be judged to be at yarn accumulation roller 21 and be wound with spinning 10 more than the necessary minimum amount of stockpiling.The minimum testing result that stockpiles quantity detection sensor 27a is sent to cell controller 60.
Spinning processing method when then illustrating that with reference to Fig. 8 to Figure 12 spinning machine 1 center tap of this example moves.
In Figure 10, when being the attraction state with " ON " expression suction pipe 44, when attracting for halted state with " OFF " expression.Extract the state that bar 28 rises with " ON " expression yarn, extract the state that bar 28 descends with " OFF " expression yarn.
If yarn clearer 52 detects the yarn defect in the coiling of spinning 10, this yarn clearer 52 sends yarn defect detection signal to cell controller 60.If cell controller 60 receives yarn defect detection signal (among the step S101 for "Yes"), make the spinning of the fibre bundle 8 that drafting system 7 or open end spinning apparatus 9 etc. carry out stop 10 cut-outs (step S102) of spin.Coiler device 13 is proceeded the coiling of package 45, is wound up into for the time being in the package 45 than the spinning 10 of off-position by the downstream.Thus, the spinning 10 that is wound up on the yarn accumulation roller 21 also is winding in the package 45, does not spin 10 on this yarn accumulation roller 21.The position that comprises the yarn defect in the spinning 10 also is wound up in the package 45 for the time being.
Then, cell controller 60 transmits control signal for joint chassis 3, makes 3 walkings of joint chassis to the front (step S103) of the spinning unit 2 that detects the yarn defect.
Then begin the joint action cycle.Be specially, cell controller 60 makes suction nozzle 46 turn to the near surface (with reference to Figure 11) of package 45, makes package 45 contrary rotations with coiler device 13.Thus, the yarn end of lower yarn is drawn out from the outer peripheral face of package 45, and this yarn end is caught (step S104) by suction nozzle 46.Partly be drawn into the attraction stream from suction nozzle 46 by pull out spinning 10 yarn defect from package 45, the part that comprises the yarn defect in the spinning 10 can be removed from package 45.
Then, cell controller 60 makes the contrary rotation of package 45, and making under the state that has attracted time yarn above suction nozzle 46 turns to, this time yarn is guided to splicer 43.Along with lower yarn is directed into splicer 43, the rotation of package 45 stops (step S105).
Cell controller 60 makes suction pipe 44 turn near the downstream of open end spinning apparatus 9 (with reference to Figure 11) before and after suction nozzle 46 rotates.Cell controller 60 again moves open end spinning apparatus 9 grades and generates spinning 10(step S107).Cell controller 60 produces from suction pipe 44 in the front and back of the generation that begins this spinning 10 and attracts stream, catches the upper yarn of the spinning 10(that is generated by open end spinning apparatus 9 with suction pipe 44) yarn end (step S108).
When suction pipe 44 caught upper yarn, cell controller 60 proceeded to attract the limit to make suction pipe 44 turn to the below by the limit, pulled out spinning 10 and guided (step S109) to splicer 43 from open end spinning apparatus 9.Although the operation (step S104 and step S105) of yarn catches the operation (step S106 and step S109) of upper yarn afterwards under catching in the flow chart of Fig. 8, this flow chart is an example of expression action just.Yarn under both can having caught behind the yarn on catching also can catch yarn and lower yarn simultaneously.
When spinning 10 finished to the guiding of splicer 43, open end spinning apparatus 9 engaged with flier 38 with spinning 10 between the suction pipe 44, and 10 coilings to yarn accumulation roller 21 begin to spin.The coiling of the package 45 that coiler device 13 carries out in the joint action stops, even but 10 also sent from open end spinning apparatus 9 continuously spinning during this period.If let alone spinning 10 like this, then produced spin 10 lax.Therefore, by will spin 10 be wound up into prevent from spinning on the yarn accumulation roller 21 10 lax.Yarn accumulation amount on yarn accumulation roller 21 after this moment increases, from the power increase of open end spinning apparatus 9 traction spinning 10.
During before yarn accumulation roller 21 stockpiles spinning 10 more than the necessary minimum amount of stockpiling, generation is skidded easily between yarn accumulation roller 21 and spinning 10, and the 10 trailed power of spinning are unsettled.Stockpile at yarn accumulation roller 21 before the spinning 10 of q.s (necessary the minimum amount of stockpiling) during the low place of spinning 10 yarn strengths of pulling out from open end spinning apparatus 9 many, be the unsettled part of spinning quality.
In the existing spinning machine, yarn end one is directed to splicer 43 by suction pipe 44, the joint action of carrying out with regard to beginning immediately splicer 43.Joint action for by the upper yarn on the assigned position that is configured in splicer 43 and lower yarn are cut off, backtwisting and twisting, with spinning 10 actions of splicing together.If carry out the joint action under above-mentioned opportunity, owing to have unsettled spinning part at yarn accumulation roller 21 as described above, therefore this unsettled spinning part has been winding in the package 45.
In order to prevent that this unsettled spinning part from sneaking into package 45, the spinning machine 1 of this example consists of as follows.
Even being directed to splicer 43 by suction pipe 44, cell controller 60 upper yarns do not begin immediately the joint action yet, with the minimum yarn accumulation amount that stockpiles on the quantity detection sensor 27a supervision yarn accumulation roller 21, judge whether to have reached the necessary minimum amount of stockpiling (step S110).For in the minimum amount of stockpiling (being "No" among the step S110), becoming decline state by making yarn extract bar 28 less than necessity, spinning 10 is winding on the yarn accumulation roller 21 in the yarn accumulation amount, and the increase of yarn accumulation amount is gone down.When detecting the yarn accumulation quantitative change and become when (being "Yes" among the step S110) more than the necessary minimum amount of stockpiling with the minimum quantity detection sensor 27a that stockpiles, cell controller 60 rises pneumatic cylinder 49, make yarn extract bar 28 and move to lifting position (step S111), from flier 38 10 excisions of will spin.
If spinning 10 is extractd from flier 38 under the state of yarn accumulation roller 21 rotations, then stop spinning 10 to disappear from the resistance of the tip side end unwinding of yarn accumulation roller 21.Even the faint attraction such as suction pipe 44 also can be with spinning 10 from 21 unwindings of yarn accumulation roller.Therefore under state shown in Figure 12, the spinning 10 on the yarn accumulation roller 21 attracts by unwinding and by suction pipe 44.Thus, the unsettled spinning 10 on the yarn accumulation roller 21 can be removed by suction pipe 44.
In the butt side of yarn accumulation roller 21, by the rotation of yarn accumulation roller 21, spinning 10 is reeled again.Because only the spinning 10 suitable with the amount that is attracted by suction pipe 44 reeled again, so the amount of stockpiling on the yarn accumulation roller 21 is maintained at roughly certain.
Therefore, pulling out from the spinning 10 of open end spinning apparatus 9 carried out on the state limit that keeps the above spinning 10 of the necessary minimum amount of stockpiling to be stockpiled, limit.As a result, again be wound up into the steady quality of spinning 10 of the butt side of yarn accumulation roller 21.From the stable spinning 10 of reeling of the butt side of yarn accumulation roller 21, on the other hand unsettled spinning 10 from the tip side of yarn accumulation roller 21 by unwinding.As a result, the spinning 10 on the yarn accumulation roller 21 is replaced as the spinning 10 of stabilised quality successively.
Pre-enter in the cell controller 60 from beginning the 10 needed times of spinning (in other words the unsettled spinning 10 of quality all being abandoned the needed time from yarn accumulation roller 21) that spinning 10 to the yarn accumulation roller 21 all is replaced as stabilised quality by making yarn extract the rise unwinding of the unsettled spinning 10 of beginning of bar 28.Cell controller 60 judges whether through this official hour (step S112).If passed through the stipulated time (being "Yes" among the step S112), then cell controller 60 descends pneumatic cylinder 49, makes yarn extract bar 28 declines (step S113).Then, cell controller 60 begins the joint action (step S114) that splicers 43 carry out.
Owing to by making yarn extract bar 28 declines flier 38 is engaged with spinning 10, therefore from not unwinding of the tip side spinning 10 of yarn accumulation roller 21, can prevent that this spinning 10 is lax.
Even in the joint that splicer 43 the carries out action, also produce attraction stream from suction nozzle 46 and suction pipe 44, attract spinning 10.In the way of joint action, the spinning 10 of not wanting is cut off by splicer 43, and the spinning 10 of should not want is attracted removes.
Joint action one finishes, and cell controller 60 just restarts the coiling of the spinning 10 that coiler device 13 carries out.
Like this, rise from repiece section 22 10 excisions of will spin by making yarn extract bar 28, the unsettled spinning 10 of the quality on the yarn accumulation roller 21 is removed by suction pipe 44, the spinning 10 that is trapped on the yarn accumulation roller 21 can be replaced as stay-in-grade spinning 10.But, rise when also having spinning 10 not extract from repiece section 22 even make yarn extract bar 28.The below with Figure 13 illustrate detect that yarn extracts that bar 28 carries out extract the structure of the baulk of spinning 10 from repiece section 22.
Cell controller 60 stockpiles testing result that detecting sensor 27b, walking detecting sensor 31 and/or yarn move detecting sensor 50 according to above-mentioned mistake and can detect yarn and extract the failure that spinning that bar 28 carries out is extractd.
At first, the failed detection of spinning excision of having used the testing result that excessively stockpiles detecting sensor 27b is described.Cross and stockpile detecting sensor 27b and can detect on the outer peripheral face 21a of yarn accumulation roller 21 spinning 10 of moving along the circumferencial direction of this yarn accumulation roller 21.Move to lifting position and spin 10 when extracing from repiece section 22 thereby extract bar 28 when yarn, as shown in figure 13, be wound up into that spinning 10 on the yarn accumulation roller 21 is extractd bar 28 by yarn and downstream thread-carrier 26 flow to the downstream.Spinning 10 becomes not, and the circumferencial direction along this yarn accumulation roller 21 moves on the outer peripheral face 21a of yarn accumulation roller 21.When making yarn extract bar 28 to move to lifting position, with crossing when stockpiling detecting sensor 27b and not detecting the spinning 10 of blocking off and on laser L27b, can be judged to be spinning 10 from 22 excisions of repiece section.Although move to lifting position making yarn extract bar 28, stockpile in the situation that detecting sensor 27b detects the spinning 10 of blocking off and on laser L27b with mistake, can be judged to be from the yarn of repiece section 22 and extract unsuccessfully.
The yarn that the testing result of having used walking detecting sensor 31 is described is extractd failed detection.Walking detecting sensor 31 detects the whether yarn road walking on waxing attachment 30 of spinning 10.After spinning 10 is cut off, make the yarn accumulation amount make for the necessary minimum amount of stockpiling ground spinning 10 engage, will spin with repiece section 22 10 be wound up on the yarn accumulation roller 21 during (making yarn excision bar 28 move to lifting position state before), the end of downstream side that is wound up into the spinning 10 on the yarn accumulation roller 21 is attracted by suction pipe 44.But, a little less than the attraction that suction pipe 44 produces, 10 unwindings of can not will spinning from the tip side end of yarn accumulation roller 21.Do not walk in the downstream of yarn accumulation device 12 spinning 10, the walking that walking detecting sensor 31 detects spinning 10 is halted state.Move to lifting position when making yarn extract bar 28, when spinning 10 is extractd from repiece section 22, stop spinning 10 to disappear from the resistance of the tip side end unwinding of yarn accumulation roller 21.Even weak attraction such as suction pipe 44 grades also can be with spinning 10 unwindings.Thus, walk in the yarn road in the downstream of yarn accumulation device 12 spinning 10, walking detecting sensor 31 detects spinning 10 and walks in the yarn road of waxing attachment 30.When making yarn excision bar 28 move to lifting position, when detecting the walking of spinning 10 with walking detecting sensor 31, can be judged to be spinning 10 and extractd from repiece section 22.Although move to lifting position making yarn extract bar 28, can't detect with walking detecting sensor 31 in the situation of 10 the walking of spinning, can be judged to be from the yarn of repiece section 22 and extract unsuccessfully.
The yarn that the testing result of having used yarn to move detecting sensor 50 is described is extractd failed detection.The detecting sensor 50 of moving yarn detects the spinning 10 of moving along the circumferencial direction of this yarn accumulation roller 21 in the tip side end of yarn accumulation roller 21.Extract bar 28 when yarn and move to lifting position, when spinning 10 was extractd from repiece section 22, as shown in figure 13, the spinning 10 that is wound up on the yarn accumulation roller 21 flow to the downstream by yarn excision bar 28 and downstream thread-carrier 26.The circumferencial direction along this yarn accumulation roller 21 does not move in the tip side end of yarn accumulation roller 21 in spinning 10.Therefore, when making yarn extract bar 28 to move to lifting position, can't detect in the situation of the spinning 10 of blocking off and on laser L50 moving detecting sensor 50 with yarn, can be judged to be spinning 10 and extract from repiece section 22.Although move to lifting position making yarn extract bar 28, move in the situation that detecting sensor 50 detects the spinning 10 of blocking off and on laser L50 with yarn, can be judged to be from the yarn of repiece section 22 and extract unsuccessfully.
Cell controller 60 stockpiles detecting sensor 27b, walking detecting sensor 31 and yarn and moves any testing result in the detecting sensor 50 and can detect yarn and extract the failure that yarn that bar 28 carries out is extractd according to crossing.Extract the yarn that bar 28 carries out and extract in the failed situation detecting yarn, cell controller 60 for example carries out again moving to lifting position after bar 28 turns back to down position in that yarn is extractd, from will the spin control of 10 excisions etc. of repiece section 22.
In the spinning machine 1 and spinning unit 2 of this example, be used for detecting the sensor extractd from the yarn of repiece section 22 (cross stockpile detecting sensor 27b, walking detecting sensor 31 and/or yarn move detecting sensor 50) by setting, can detect spinning 10 and whether picked-off from repiece section 22 by being used for detecting sensor that yarn extracts.Thus, can prevent the problem that produces in the situation of extracing from the yarn of repiece section 22 not detecting.
Use is arranged on the walking detecting sensor 31 in the waxing attachment 30 or detects mistake that the mistake of spinning 10 stockpiles and stockpiles detecting sensor 27b and can detect spinning 10 and picked-off from repiece section 22.Thus, there is not to arrange the necessity be used for detecting the new sensor of extracing from the yarn of repiece section 22.
Whether also can detect spinning 10 in the spinning unit 2 that possesses open end spinning apparatus 9 extracts from repiece section 22.
