In addition, be provided with in the lower end that above-mentioned thread path forms parts 75 and draw sensor 154, this is drawn sensor 154 and can in fact detect to connecing the situation that yarn portion 8 sides draw the yarn ends that is rolled into the yarns Y in the reservoir 61.This is drawn sensor 154 and is electrically connected with control part 109,, will be drawn detection signal and send to control part 109 by after connect the situation that yarn portion 8 sides draw in the yarn ends that detects yarns Y.

And, in reservoir 61, be provided with for detection of the holding of allowance of holding of yarns Y and stay upper limit sensor 155, hold and stay limit sensor 156, hold and stay lower limited sensor 157.Hold stay upper limit sensor 155, hold when staying limit sensor 156 and holding and staying lower limited sensor 157 to be positioned in holding allowance and becoming 300m, 200m and 40m of yarns Y in the reservoir 61 respectively, rotate on the relative position, the upper end of holding the wire harness that stays the yarns Y on the reel 71 with being wound on.

Here, 300m refer to for example carry out repeatedly three times (at least one times) described later connect yarn during, length more than the length of the textile yarn Y that is reeled by coiling portion 5, as described later, even when during connecing yarn, continuing the coiling of the textile yarn Y in the coiling portion 5, in reservoir 7, also be difficult to take place the situation that the yarn of textile yarn Y lacks.

And, in this constitutes, hold and stay upper limit sensor 155, hold and stay the duration of existence that limit sensor 156 and holding stays the yarns Y of lower limited sensor 157 in detecting relative position, send to control part 109 respectively and hold limited signal on the allowance, hold under the allowance limited signal and hold allowance and descend limited signal most.

In addition, stay upper limit sensor 155 upper right side relative, that hold the yarns Y when staying reel 71 to be wound with the yarns Y of 300m in rotation not hold the upper right end of staying reel 71 in rotation with holding, hold the position, way that the regulation of staying reel 71 is held in the rotation of the substantial middle portion of staying reel 71 etc. and be arranged in for example rotation.

Below, the formation of the control part 109 of winder unit 2 is described.That is control part 109, shown in Figure 3 has: as the CPU (Central Processing Unit) of arithmetic processing apparatus; Store the control program of CPU execution and the ROM (Read Only Memory) of the employed data of control program; The above-mentioned RAM of temporary storaging data when program is carried out (Random Access Memory).And, being stored in above-mentioned control program among the ROM is read into CPU and carries out by CPU, thus, control program make hardware such as CPU as reel spool motor controling part 160, rotation hold stay reel motor controling part 161, draw length of yarn operational part 163, on manage control part 164 and play a role.

Reel spool motor controling part 160 is parts that the rotative speed of reel spool motor 116 is controlled, by above-mentioned hold that the allowance test section detects hold allowance less than specified value the time, the winding speed Va of coiling yarns Y is slowed down in described coiling portion 6.

Specifically, reel spool motor controling part 160 stays the holding under the allowance behind the limited signal of limit sensor 156 stopping to receive from holding, so that in the degree of the thread layers confusion reigned of package 30 above-mentioned winding speed Va is slowed down.And, reel spool motor controling part 160 stop to receive from hold stay the holding allowance and descend limited signal most of lower limited sensor 157 after, winding speed Va is slowed down rapidly, and the coiling that is undertaken by coiling portion 6 is stopped.

Like this, holding when allowance reduces of the yarns Y of reel spool motor controling part 160 in reservoir 61 slowed down winding speed Va, and, holding of yarns Y at reservoir 61 makes the coiling that is undertaken by coiling portion 6 stop when allowance becomes few, thus, the yarn that can prevent the yarns Y in the reservoir 61 lacks in possible trouble.

Rotation holds that to stay reel motor controling part 161 be that the parts that the hand of rotation that stays reel motor 72 is controlled are held in rotation, left-hand tools is held when staying on the reel 71 the coiling yarns Y, hold with rotation and to stay reel 71 to control rotation to the mode of direction rotation to hold and stay reel motor 72, hold the yarn ends of staying the yarns Y on the reel 71 when connecing yarn portion 8 sides and draw in rotation, to hold and stay reel motor 72 to controlling rotation with the mode of holding direction rotation opposite when staying coiling yarn on the reel 71 in rotation.In addition, rotation is held and is stayed reel motor controling part 161 (rotative speed control mechanism) as described later, also is rotated the control of holding the rotative speed that stays reel motor 72.

Draw length of yarn operational part 163, be to from draw sensor 154 detect that moment of yarns Y begins, hold the anglec of rotation of staying reel motor 72 based on the rotation that is detected by rotary encoder 153, computing from reservoir 61 to the parts of drawing length of yarn as the length of yarn of yarns Y that connect that yarn portion 8 sides draw.

The yarn defect length that 164 pairs of last pipe control parts are obtained from yarn defect detection signal and compare by drawing the length of yarn of drawing that length of yarn operational part 163 calculates, and after drawing length of yarn arrival yarn defect length, state with yarn guiding tube 26 in the clamping makes its rotation, thereby the yarns Y of coiling portion 6 sides is guided and setting to connecting device 14.

Below, utilize Fig. 4～Fig. 7 that the action of winder unit 2 is described.

The operator of automatic bobbin winder (winder unit 2) makes the yarns Y unwinding from yarn feeding spool 21, and this yarns Y is arranged on unwinding yarn auxiliary device 12, yarn contact pilotage 37, first tensioner 41, yarn yarn clearer 15, reservoir 61, second tensioner 42, the waxing attachment 17, and be fixed on the coiling spool 22.The yarn road of the yarns Y in the reservoir 61 as shown in Figure 2.That is, the operator make yarns Y successively by draw sensor 154, thread path form parts 75 thread path 128, blow down the yarn stream 146 of nozzle 74, the internal flow path of yarn guide member 73.Under this state, the operator stays reel 71 opening opposing to draw yarns Y from holding with rotation of yarn guide member 73, and it is held in rotation stay reel 71 to reel for example about 5～20 circles, and, and it is held by rotation stay between reel 71 and the endless member 81, be arranged on then to be configured in to rotate and hold on the top-right yarn guide spare 82 that stays reel 71, it is arranged on second tensioner 42 then.In addition, the convenience of the yarns Y among Fig. 2 in order to illustrate all described slightlyer, and it reels and also to become big at interval, but in fact, always can hold in rotation and stay reel 71 to hold to stay the wire harness of the yarns Y about 600 circles of having reeled at interval with little coiling.

(when reeling usually)

Under this state, as shown in Figure 4, behind the power supply of connection winder unit 2 (S300), the mode of 1200m/min begins the rotation of reel spool 24 to control part 109 (rotation is held and stayed reel motor controling part 161) so that for example become based on the winding speed Va of the yarns Y of coiling portion 6, and, begin to rotate and hold the rotation (S310) of staying reel motor 72 so that the winding speed Vb that the yarns Y of staying in the reel 71 is held in rotation for example becomes the mode of 1500m/mmin.

Like this, be wound on rotation and hold the yarns Y of staying on the reel 71 and begin unwinding from upper right side successively by coiling portion 6, and be wound in the package 30 while traversing by reel spool 24.

At this moment, yarns Y is held between the surface and endless member 81 of staying reel 71 by rotation with the state that is held, and the burr of yarns Y is lodged.In addition, because being clamped in rotation, yarns Y holds between the surface of staying reel 71 and the endless member 81 (being endowed resistance), so, give tension force to yarns Y.And, by this tension force, can prevent that holding the yarns Y of staying reel 71 unwindings and moving to coiling portion 6 from rotation expands (generation air ring).In addition, at this moment, be wound on that the endless member that stays on the reel 71 81 is held in rotation owing to hold with rotation and to stay the rotation of reel 71 one, so, endless member 81 can not hold with respect to rotation and stay reel 71 to move, and thus, endless member 81 can not hold with rotation and stay reel 71 to rub mutually and be worn away.

In addition, meanwhile, the yarns Y of yarn feeder 5 sides is held the tapered portion 71a guiding of staying reel 71 by yarn guide member 73 to rotation as shown in Figure 2, holds by rotation and stays reel 71 to rotate to a direction centered by axle C, and the yarns Y that is directed is wound onto on the tapered portion 71a.

And the yarns Y that is wound onto on the tapered portion 71a moves to the upper right side with axle C almost parallel ground along the surface of tapered portion 71a successively.And thus, yarns Y is held to stay to rotate to hold to be stayed on the reel 71.

Like this, in the present embodiment, the yarns Y that is directed to tapered portion 71a is held the rotation of staying reel 71 by rotation and is wound onto on the tapered portion 71a, and move in the mode of sliding to the upper right side along the surface of tapered portion 71a, thus, the yarns Y that previous yarns Y of reeling is newly reeled boosts, and stays on the reel 71 and hold successively to stay to rotate to hold.Therefore, yarn guide member 73 be so long as can guide to yarns Y any parts of tapered portion 71a and get final product, regardless of rotate hold the position of staying reel 71 and towards, can both be configured with comparalive ease.Therefore, can be according to the free space of winder unit 2 etc., configuration rotation is more freely held and is stayed reel 71.

In addition, different with present embodiment, replace rotation to hold staying reel 71 that fixing holding can also be set staying reel, and, be provided with for hold the mechanism of staying reel coiling yarns Y to this, under this situation, this mechanism is in order to stay reel to reel to holding yarns Y, and have hold stay reel around the part of rotation, in any case but the path that is formed on the yarns Y on this part all can become the more structure of number of bends.Its result is, the number of bends of the yarns Y by such path also becomes many, becomes the major reason that the quality that causes yarns Y reduces.

But, in the present embodiment, because holding, rotation stays reel 71 rotations, so, yarns Y is wound onto to rotate to hold and stays on the reel 71, therefore do not have the mechanism be used to the coiling that carries out yarns Y as described above, can also be used in and yarns Y is guided to rotation hold the path of staying reel 71 and form the path structure such, that number of bends is few that the inner space by thread path 128, the yarn stream 146 of blowing down nozzle 74 and yarn guide member 73 constitutes, can prevent that the quality of yarns Y from reducing.

And, like this, when under the state that links from yarn feeder 5 to coiling portion 6 yarns Y, carrying out common coiling that yarns Y reels to package 30, control part 109, as shown in Figure 4, the having or not of reception of broken yarn signal confirmed (S320), the having or not of reception of yarn defect detection signal confirmed (S330), having or not of reception to the empty spool signal confirmed (S340), and the having or not of reception of holding limited signal on the allowance confirmed (S350).

And, at (S320:YES) under the situation that receives the broken yarn signal, receiving (S330:YES) under the situation of yarn defect detection signal and receiving under the situation of empty spool signal (S340:YES), respectively execution graph 5, Fig. 6, control flow chart (S325, S335, S345) shown in Figure 7 return to the control flow chart of Fig. 4 then.

In addition, after the beginning of reeling, soon, owing to rising to, winding speed Vb is higher than winding speed Va, so the allowance of holding of the yarns Y of reservoir 61 increases gradually, subsequently, after the holding allowance and arrive 300m of yarns Y, hold and stay upper limit sensor 155 to send to control part 109 to hold limited signal on the allowance.Control part 109 (rotation is held and stayed reel motor controling part 161), as shown in Figure 5, staying upper limit sensor 155 to receive to hold on the allowance behind the limited signal (S350:YES) from holding, change rotation and hold the rotative speed that stays reel motor 72, thus, make winding speed Vb be altered to 1200m/min (S360) from for example 1500m/min.Thus, winding speed Va is consistent with winding speed Vb, and the allowance of holding of reservoir 61 becomes constant.

Here, as previously mentioned, because it is relative to hold the part of staying upper limit sensor 155 and rotation to hold in the way of staying reel 71, so, hold in rotation and to stay in the reel 71, only than staying the relative part of upper limit sensor 155 to be wound with yarns Y near the part of lower-left distolateral (reel for yarn is around the け side) with holding, comparing with it near the part of upper right distolateral (unwinding yarn side) yarns Y of not reeling.

Therefore, hold from rotation the yarns Y staying reel 71 unwindings and move to coiling portion 6 rotation hold stay reel 71, than staying the relative part of upper limit sensor 155 to move near the rolling limit, surperficial top of upper right distolateral part with holding, thus, the burr of yarns Y is lodged.

(during broken yarn)

Below, the action shown in the control flow chart of the Fig. 5 under the situation that broken yarn takes place is described.Broken yarn is taking place, and control part 109 receives (S320:YES) behind the broken yarn signal from yarn yarn clearer 15, and control part 109 at first stops the rotation and holds the rotation (S410) of staying reel 71.

Next, control part 109 switches electromagnetic valve 152 to open state, thus, forms in the inner space of yarn guide member 73, thread path 128 etc. and holds the air that stays yarn guiding tube 26 sides on reel 71 side direction from rotation and flow (S420).

Meanwhile, the attraction mouth 26b that control part 109 will be gone up yarn guiding tube 26 switches to open state from closed state, thus, forms in last yarn guiding tube 26 from attracting mouthful air stream (S420) of 26b side direction negative pressure source 120 sides.

Then, rotation hold stay reel motor controling part 161 so that rotation hold stay the side of reel 71 towards with the coiling yarns Y time in the opposite direction the mode that is rotated of low speed rotation held stay reel motor 72 to control (S430), become and wait for and receiving from the state of drawing detection signal (S440:NO) of drawing sensor 154.

Like this, the opening that the yarn ends of staying existing yarns Y on the reel 71 is inhaled into yarn guide member 73 is held in rotation, and draws via the attraction mouth 26b of the yarn guiding tubes 26 that make progress such as thread path 128.At this moment, since rotation hold stay reel motor 72 be can the control position motor, so, can make rotation hold the residing part of the yarn ends of staying the yarns Y in the reel 71 and move to the position relative with the opening of yarn guide member 73 accurately, thus, can suck the yarn ends of yarns Y reliably from the opening of yarn guide member 73.

And, as previously mentioned, because yarn guide member 73 guides to tapered portion 71a with yarns Y, so guiding to moving direction that rotation holds the yarns Y of staying reel 71 from yarn guide member 73, to relate to that rotation holds axial (direction parallel with axle C) of staying reel 71 and become from its unwinding yarn side end be that upper right side side direction tapered portion 71a side is the distolateral direction in lower-left.

Therefore, the yarns Y that is directed to tapered portion 71a is held inertia when staying reel 71 by move to rotation from yarn guide member 73, can not hold the upper right side side shifting of staying reel 71 to rotation, the yarn ends of yarns Y is positioned at rotation reliably and holds near the tapered portion 71a that stays reel 71, say that closely the yarn ends of yarns Y is come on the end, lower-left of line part 71c.Therefore, can be reliably suck yarns Y from the opening of yarn guide member 73.

In addition, yarn guide member 73 attracts the mode of two actions can carry out yarns Y to the guiding of tapered portion 71a and to the yarn ends of the yarns Y on the end, lower-left that is positioned at line part 71c, and the opening of its left upper end is disposed to stride across this two-part mode.

And,, draw sensor 154 and draw detection signal to control part 109 transmissions by after drawing sensor 154 in yarns Y.From draw sensor 154 receive draw detection signal after (S440:YES), control part 109 holds the state of the low speed rotation of staying reel 71 to continue rotation, to attract a mouthful 26b to switch to closed state from open state, and by holding part 26c clamping yarns Y, and yarn guiding tube 26 is rotated from the top down, thus, will guide (S450) to the connecting device 14 that meets yarn portion 8 from the yarns Y that reservoir 61 is drawn.

At this moment, rotation by last yarn guiding tube 26, yarns Y is drawn about general 60cm again from reservoir 61, but this moment, in order not make yarns Y hold to stay between the reel 71 in holding part 26c and rotation broken yarn takes place, control part 109 makes the rotation of yarn guiding tube 26 hold with rotation to stay the rotation of reel 71 synchronous.By on yarn guiding tube 26 carry out yarns Y is finished back (S450) to the guiding of connecting device 14, control part 109 makes rotation hold the rotation of staying reel 71 to stop (S460).

On the other hand, yarn under working guiding tube 25 and last yarn guiding tube 26 similarly attract to catch to the yarn ends of the peripheral existing yarns Y of yarn contact pilotage 37, and with this yarns Y to connecting device 14 guiding.And after the yarns Y with the yarns Y of reservoir 61 sides and yarn feeder 5 sides was arranged on the connecting device 14, control part 109 was carried out connecting device 14 and is connect yarn operation (S470).

Then, control part 109 as shown in Figure 2, holds rotation and stays reel 71 beginnings to the rotation (S480) of a direction, and return to above-mentioned common reeling condition (S490).In addition, Ci Shi rotation is held the rotating speed that stays reel 71 and is set (S480) in the mode that winding speed Vb becomes 1500m/min.

(when the yarn defect detects)

Below, the represented action of control flow chart under the situation that detects the yarn defect, Fig. 6 is described.But, because same when the part of action of this moment and broken yarn, so in the following, its detailed explanation is omitted in same action about with broken yarn the time.

Detecting the yarn defect, after control part 109 received yarn defect detection signal from yarn yarn clearer 15, yarn shutoff signal, the order of control part 109 same above-mentioned S410～S440 according to broken yarn the time was moved.And, from draw sensor 154 receive draw detection signal after (S440:YES), draw length of yarn operational part 163 and obtain from drawing sensor 154 and detect rotation that moment of yarns Y begins, that detected by rotary encoder 153 and hold the anglec of rotation (S570) of staying reel 71, and based on the described length of yarn (S580) of drawing of this anglec of rotation computing.

And, on manage the length of the yarn defect that 64 pairs of control parts obtain from yarn defect detection signal and compare (S590) by the length of yarn of drawing of drawing 63 computings of length of yarn operational part.And, 164 standbies of last pipe control part reach yarn defect length (S590:NO) to drawing length of yarn, after reaching yarn defect length (S590:YES), during with broken yarn similarly the order according to above-mentioned S450～S480 move, thus, connect yarn and to the recovery of common reeling condition.

(when spool is changed)

Below, the represented action of control flow chart under the empty situation of yarn feeding spool 21 changes, Fig. 7 is described.But because the part of action under this situation is identical during with broken yarn, so, below in, its detailed explanation is omitted in same action about with broken yarn the time.

Become empty at yarn feeding spool 21, control part 109 receives (S340:YES) behind the empty spool signal from yarn contact pilotage 37, discharging current yarn feeding spool 21 also loads new yarn feeding spool 21 to yarn feeding spool maintaining part 60, to the yarns Y channeling conduct of this yarn feeding spool 21, become and to be caught the state (S710) that attracts by yarn under working guiding tube 25.And the situation during with broken yarn is same, by the action of above-mentioned S410～S440, connects yarn and to the recovery of common reeling condition.

And, in the winder unit 2, by moving as described above, even when meeting yarn portion 6 and connect yarn, also can stay yarn and hold the textile yarn Y that stays on the reel 27 and carry out unwinding holding, thus, during connecing the yarn operation and carrying out once at least, also can in coiling portion 5, continue the coiling of textile yarn Y-direction package P.That is, under the situation that the coiling of textile yarn Y-direction package P that can be in not making coiling portion 5 interrupts, connect yarn by meeting yarn portion 6.

In addition, by rotation being held stay reel 271 opposite direction rotation to the coiling of yarns Y the time, yarns Y can be drawn to connecing yarn portion 8 sides, so, yarns Y can be drawn to meeting yarn portion 8 reliably.

And, by carry out simultaneously the coiling action that undertaken by coiling portion 5 and by rotation is held stay reel 271 to the coiling of yarns Y the time opposite direction rotation and with yarn to connecing the action of drawing that yarn portion 8 sides draw, can carry out the coiling of yarns Y simultaneously and connect yarn.

In addition, in the yarn winder unit 2 of above explanation, thereby the tension force transmission of configuration yarn reserving portion 9 blocking yarns Y between yarn feeding spool 21 and coiling portion 6 thus, can prevent that tension change that the change of traversing because of coiling portion 6 causes from partly transmitting to the unwinding tension of yarn feeding spool 21.And, by at yarn feeding spool 21 apparatus for unwinding 12 being installed, can stably carry out from the unwinding yarn of yarn feeding spool 21, so, can prevent broken yarn, and then can accelerate from the withdrawal speed of yarn feeding spool 21.Therefore, can improve unwinding efficient from yarn feeding spool 21.

Next, describe having appended various variation after changing in the present embodiment.But, for having the identical mark of the parts mark of same formation with present embodiment, suitably omit its explanation.

In the variation, as shown in Figure 8, thread path forms the above-mentioned embodiment weak point of aspect ratio of parts 75 (thread path 128).In addition, the rotation hold stay reel 71, the rotation hold stay reel motor 72, yarn guide member 73 and blow down nozzle 74 compare with above-mentioned embodiment be positioned at the below, and, compare with above-mentioned embodiment, form parts 75 left to the figure from thread path and leave at interval configuration significantly.And, thread path being installed in the end, bottom right of blowing down nozzle 74 forming parts 76, the yarn stream 146 of blowing down nozzle 74 is connected with thread path 128 via the thread path 129 of the inside that is formed on thread path formation parts 76.

Under this situation, rotation can be held and stay reel 71 grades to be configured in to compare with the situation of above-mentioned embodiment on the low position, can make winder unit 2 be positioned at the height of the winder unit that does not have reservoir 61 with degree on.

In addition, this variation is compared with above-mentioned embodiment, rotation is held the position of staying reel 71 grades and is existed more different, but can also change the height that thread path forms parts 75 (thread path 128), in the end, bottom right of blowing down nozzle 74 thread path is installed and is formed parts 76, thereby only by yarn stream 146 is connected via thread path 129 with thread path 128, and with above-mentioned embodiment similarly to tapered portion 71a guiding yarns Y.And from this situation also as can be known, rotation is held and is stayed the reel 71 can be according to configurations more freely such as the free spaces of winder unit 2.

In addition, in the above-mentioned embodiment, yarn guide member 73 is the parts of the tubulose of pipe etc., blowing down nozzle 74 makes and holds the air stream that stays yarn guiding tube 26 sides on reel 71 side direction from rotation and be created in the inner space of yarn guide member 73, thus, the yarn ends of staying the yarns Y on the reel reel 71 is held in rotation attracted and catch, but be not limited thereto.For example, replace blowing down nozzle 74, can also arrange and stay the yarn ends of the yarns Y on the reel to attract to being positioned to rotate to hold, and, the yarns Y that attracts is taken to the attraction mouth 26b of yarn guiding tube 26 mechanism etc., can hold other the mechanism of staying that the yarn ends of holding the yarns Y of staying on the reel 71 catches to rotation.And, under this situation, as long as yarn guide member 73 can be not limited to the parts of tubulose with yarns Y to tapered portion 71a guiding.

In addition, in the above-mentioned embodiment, hold the upper right end of staying reel 71 in rotation, as giving the endless member 81 that resistance mechanism is wound with rubber system, the parts that the material but endless member 81 can also be served as reasons beyond the rubber such as synthetic resin material for example constitutes.

And, give resistance mechanism and if rotation hold clamping yarns Y between the surface of staying reel 71, be not limited to be wound on rotation and hold the endless member that stays on the reel 71, can also be to be configured in rotation to hold the parts of the outside of staying reel 71.Here, giving resistance mechanism to stay reel 71 to rub mutually and is worn away in order to prevent from holding with rotation, preferably holding with rotation stays reel 71 to rotate integratedly, but resistance mechanism is inferior by the situation that the material that is difficult to wear away constitutes for example giving, can also be fixed on rotation hold the parts of the outside of staying reel 71 first-class do not hold the parts that stay reel 71 to rotate integratedly with rotation.And, can adopt with rotating and hold the becket that stays reel 71 to separate the space of regulation and be mounted.

Perhaps, yarns Y and rotation hold under the upper right end state of contact of staying reel 71 by mobile and yarns Y is given under the situation of sufficient resistance and rotation hold stay be provided with in addition between reel 71 and the coiling portion 6 for the situation of the mechanism that yarns Y is given resistance inferior, can also not arrange by its with rotate the resistance mechanism of giving of holding clamping yarns Y between the surface of staying reel 71 and yarns Y being given resistance.

In addition, in the above-mentioned embodiment, it is relative to hold the part of staying upper limit sensor 155 and rotation to hold in the way of staying reel 71, only be positioned at the distolateral part in lower-left and be wound with yarns Y comparing with this part, but hold and stay upper limit sensor 155 to hold with rotation to stay the upper right end of reel 71 relatively to dispose, hold in rotation and stay the roughly whole zone of reel 71 to be wound with yarns Y.In addition, under this situation, above-mentioned to pass through the effect that yarns Y holds the mobile burr lodging that makes yarns Y in the surface of staying reel 71 in rotation faint, stays rotation and hold and stay the amount of the yarns Y on the reel 71 to increase but can hold.

In addition, in the above-mentioned embodiment, the both ends of staying reel 71 are held in rotation to be become its diameter of distolateral part along with the trend opposition side respectively and becomes more little

tapered portion

71a, 71b, but about the upper right end of Fig. 2, can also make its constant diameter.

In addition, in the above-mentioned embodiment, rotation is held a part of staying reel motor 72 and is held from rotation and stay reel 71 to stretch out, and stays reel 72 to be accommodated in rotation fully to hold the inside of staying reel 71 but rotation can also be held.And, under this situation, hold with rotation and to stay reel motor 72 not hold from rotation to stay amount that reel 71 stretches out correspondingly, can more freely dispose rotation and hold and stay reel 71.

And in the above-mentioned embodiment, when broken yarn, when the yarn defect detects, when spool is changed, the yarns Y in downstream becomes and is wound onto rotation fully and holds the state that stays on the reel 71.But, can also implement following mode, namely when broken yarn, when the yarn defect detects, when spool is changed, detect it in advance and take place, and be wound on rotation fully in the yarns Y in downstream and hold and rotation is held before staying on the reel 71 to stay the driving of reel 71 to stop.For example, when carrying out the detection of yarn defect, when the cutter that yarn yarn clearer 15 has cuts off yarns Y, rotation is held and stay the driving of reel 71 to stop.In addition, when spool is changed, the sensor of the residual amount of thread of installation and measuring yarn feeding spool 21 on unwinding yarn auxiliary device 12, the residual amount of thread of supervision yarn feeding spool 21.And, can implement following mode, namely detect the generation of the dummy status of yarn feeding spool 21 in advance, and be wound on rotation fully at the textile yarn Y in downstream and hold and rotation is held stay the driving of reel 71 to stop.

Like this, being wound on rotation fully in yarns Y holds and rotation is held stay the driving of reel 71 to stop, thus, can to blowing down under the state that upstream side that nozzle 74 or thread path form parts 75 hangs down of reservoir 61 it be stopped in the yarn ends of yarns Y.

Therefore, the yarn ends of the state that hangs down in the below that last yarn guiding tube 26 can subtend reservoir 61 catches, so, can cut down the operation of drawing of the yarns Y of being undertaken by the yarn ends derivation mechanism, improved and connect the yarn efficiency of operation.In this form, owing to be provided with and draw sensor 154, so, can detect and hold the yarn ends of staying the yarns Y in the reservoir 61 and stop at the state of received position by last yarn guiding tube 26, be i.e. the state that under the state that yarn ends hangs down to the upstream side of reservoir 61, stops reliably.Thus, can shorten the yarn ends of yarns Y is drawn the needed time from described yarn reserving portion to the described yarn portion side that connects.

Like this, derivation mechanism of the present invention not only can be drawn the yarns Y that is wound on fully on the reservoir 61, the yarns Y that stops under the state of below of reservoir 61 can also be drawn to connecing yarn portion 8 sides.In addition, about rotative speed, the rotative speed shown in the present embodiment is an example, can also implement with other rotative speed, other speed unit.
