At this, in the 1st embodiment, at the 71c of straight flange section of rotation reserving portion 71, an end of winder 6 sides of the yarns Y that winds should residing scope (being wrapped in the winding width of the yarns Y on the 71c of straight flange section) be predesignated into to the scope R1 shown in Fig. 2.Thus, the scope of holding allowance of the yarns Y of rotation in reserving portion 71 is set following scope for: the yarns Y when yarns Y of take is wound to the maximum (upper right side in Fig. 2) of scope R1 to hold allowance (300m left and right) be the upper limit, the yarns Y when yarns Y of take is wound to the minimum place (the lower-left end in Fig. 2) of scope R1 to hold allowance (about 40m) be lower limit.

And, in the 1st embodiment, as described later, in order in above-mentioned scope R1, in rotation, to hold on reserving portion 71 and to stay yarns Y, by Yarn senser 155～157, detects respectively the yarns Y of rotating in reserving portion 71 hold allowance whether be compared to the A1 that the above-mentioned upper limit position that holds the scope R1 of allowance stipulates many, whether be compared to that A2 that the above-mentioned half-way of holding the scope R1 of allowance stipulates is many and whether to be compared to the A3 stipulated above-mentioned lower position of holding the scope R1 of allowance many.

In addition, yarns Y hold be left to scope R1 on the allowance of holding of yarns Y in the rotation reserving portion 71 of prescribing a time limit set that to hold allowance few than can actually holding the maximum of staying the yarns Y on rotation reserving portion 71 for, thus, as described later, even the yarn in rotation in reserving portion 71 hold allowance when temporarily many than above-mentioned A1, yarns Y can not overflowed from rotation reserving portion 71 yet.

Next, the structure of the control part 109 of winder unit 2 is described.As shown in Figure 3, control part 109 has: as the CPU (Central Processing Unit, central process unit) of arithmetic processing apparatus; The ROM (Read Only Memory, read-only memory (ROM)) of the data that store the performed control program of CPU and use in control program; With above-mentioned RAM (Random Access Memory, random access memory) for temporary transient storage data when the executive routine etc.And, the above-mentioned control program be stored in ROM is read by CPU and carries out on CPU, thus, control program make the hardware such as CPU as reel spool motor control section 160, rotation hold stay drum motor control part 161, draw length of yarn operational part 163, upper pipe control part 164, lower pipe control part 165 and performance function.

Reel spool motor control section 160 controls the rotative speed of reel spool motor 116.Rotation is held and is stayed the 161 control rotations of drum motor control part to hold hand of rotation and the rotative speed that stays drum motor 72.

Draw that length of yarn operational part 163 is that start according to the moment that yarns Y detected from drawing sensor 154, the anglec of rotation of staying drum motor 72 is held in rotation that detected by rotary encoder 153, the length of yarn of drawing as from reservoir 61 to the length of yarn that connects the yarns Y that yarn section 8 sides draw is carried out to computing.

The yarn faults length that 164 pairs of upper pipe control parts are obtained from the yarn faults detection signal and comparing by drawing the length of yarn of drawing that length of yarn operational part 163 calculates, when drawing length of yarn while reaching yarn faults length, make yarn guiding tube 26 with the clamp position rotation, the yarns Y of winder 6 sides is guided, arranges to connecing yarn feeding device 14.Lower pipe control part 165 makes yarn under working guiding tube 25 with the clamp position rotation, and the yarns Y of yarn feeder 5 sides is guided, arranges to connecing yarn feeding device 14.

Next, use Fig. 4～Fig. 7 that the coiling action of the yarns Y in winder unit 2 is described.

The operator of automatic bobbin winder (winder unit 2) by yarns Y from 21 unwindings of yarn feeding spool, this yarns Y is arranged on unwinding yarn auxiliary device 12, yarn detector 37, the 1st tensioner 41, yarn clearer 15, reservoir 61, the 2nd tensioner 42, Wax applyor 17, and is fixed on coiling spool 22.The yarn route of the yarns Y in reservoir 61 as shown in Figure 2.That is, the operator makes yarns Y in order through drawing sensor 154, the thread path 128 of thread path formation parts 75, the internal path of blowing down yarn path 146 and the yarn guide member 73 of nozzle 74.

Under this state, the operator draws yarns Y from the opening relative with rotation reserving portion 71 of yarn guide member 73, it is wound around to for example 5～20 left and right on rotation reserving portion 71, and then, through between rotation reserving portion 71 and endless member 81 and be arranged on to be disposed at and rotate on the top-right thread guides 82 of reserving portion 71, then be arranged on the 2nd tensioner 42.In addition, for convenience of explanation, in Fig. 2 yarns Y describe slightly and its to be wound around interval also larger, leave but hold all the time in reality the wire harness that are wound around the yarns Y of hundreds of circles left and right with little winding interval on rotation reserving portion 71.

Then, under this state, drive rotation to hold and stay drum motor 72 and reel spool motor 116.Thus, make the yarns Y unwinding of yarn feeding spool 21 by the rotation of rotation reserving portion 71, the yarns Y of unwinding is wrapped on the 71a of tapering.The yarns Y be wrapped on the 71a of tapering moves to the 71c of straight flange section along the surface of tapering 71a, and thus, yarns Y axially is wrapped on rotation reserving portion 71 along rotation reserving portion 71.In addition, the rotation by reel spool 24 makes to hold the yarns Y unwinding of staying on rotation reserving portion 71, and is wound on the coiling spool 22 of rotation together with reel spool 24.That is,, in winder unit 2, yarns Y starts to reel.And, during the coiling that carries out yarns Y by winder unit 2, control the rotative speed of rotation reserving portion 71 and reel spool 24 etc. according to the flow process of Fig. 4 and Fig. 5.

The action of rotation reserving portion 71 is described.In the 1st embodiment, as described later, when making to rotate reserving portion 71 and stop the rotation, the yarns Y of take makes rotate reserving portion 71 rotations as the such rotative speed of maximum Vc from the unwinding yarn speed of yarn feeding spool 21 in can be by the scope of the normal unwinding of yarns Y.At this, above-mentioned Vc is defined as according to material and the thickness of yarns Y, when yarns Y can not occurred during from 21 unwinding of yarn feeding spool to for the scope of the unfavorable conditions such as knocking over (sloughing) of yarns Y.In addition, in the present invention, the unwinding yarn speed means the speed from the yarns Y of yarn feeding spool unwinding by rotation reserving portion 71.

And, as shown in Figure 4, under the state of rotation reserving portion 71 rotations (S101: be), the defect (S102: no) that yarns Y do not detected by yarn clearer 15 and detect yarns Y have (S103: be) time,, when yarns Y mobile being detected, make to rotate reserving portion 71 and continue rotation under this state.On the other hand, when the defect of yarns Y being detected by yarn clearer 15 (S102: be), or, when the existing of yarns Y not detected (S103: no), make to rotate reserving portion 71 and stop the rotation (S104), and turn back to above-mentioned S101.

On the other hand, thereby in above-mentioned S104, make to rotate under the state that the rotation reserving portions 71 such as reserving portion 71 stops the rotation stop the rotation (S101: no), based on connect that yarn section 8 carries out connect before the yarn release during (S105: no), rotation reserving portion 71 is remained on to the state that rotation stops, based on connect that yarn section 8 carries out connect the yarn release time (S105: be), make to rotate reserving portion 71 and again start rotation (S106), and turn back to above-mentioned S101.

Next, the action of reel spool 24 is described.As shown in Figure 5, in the situation that the yarns Y of rotation in reserving portion 71 to hold allowance more than A3 (lower limit holds allowance),, stay (S201: be) in the situation that holding of the yarns Y more than the regulation lower limit detected by lower limit Yarn senser 157, in the defect (S202: no) that yarns Y do not detected by yarn clearer 15 and while the existing of yarns Y being detected (S203: be),, when yarns Y mobile being detected, according to the rotative speed that allowance changes reel spool 24 that holds of the yarns Y in rotation reserving portion 71.

Particularly, in the situation that holding of the yarns Y more than set upper limit detected by upper limit Yarn senser 155, stay,, in the situation that the yarns Y of rotation in reserving portion 71 hold allowance than A1 many (S204: be), make reel spool 24 take the winding yarn speed of yarns Y as than unwinding yarn speed being the such regulation rotative speed rotation of V1 that Vc is fast, continue the coiling (S205) of yarns Y on coiling spool 22, and turn back to S201.In addition, in the present invention, winding yarn speed means to be wound into by the rotation of reel spool 24 speed of the yarns Y of package.

On the other hand, in the situation that yarns Y do not detected by upper limit Yarn senser 155,, in the situation that the allowance of holding of the yarns Y in rotation reserving portion 71 is (S204: no) below A1, make reel spool 24 take the winding yarn speed of yarns Y as than unwinding yarn speed being the such regulation rotative speed rotation of V2 that Vc is slow, continue the coiling (S206) of yarns Y on coiling spool 22, and turn back to S201.

In addition, by lower limit Yarn senser 157, detecting under the state that holding of the yarns Y more than the regulation lower limit stay (S201: be), when by yarn clearer 15, on yarns Y, defect being detected (S202: be), or when the existing of yarns Y not detected (S203: no),, in the situation that the movement of yarns Y do not detected and yarns Y (S207: be) detected by middle Yarn senser 156, owing to holding the yarns Y of holding the amount that allowance is more than A2 that leaves the yarns Y in rotation reserving portion 71, so maintaining continuation coiling (S208) under the state of winding speed.In other words, with the rotative speed with (S203: be) is identical when the existing of yarns Y being detected, particularly, take winding yarn speed as the such rotative speed of V1, in the situation that yarn holds allowance take winding yarn speed continue the coiling of yarns Y to coiling spool 22 as the such rotative speed of V2 below A1 in the situation that yarn holds allowance than A1.And, then, turn back to S201.

On the other hand, in the situation that the allowance of holding of the yarns Y of rotation in reserving portion 71 is below A2 and yarns Y (S206: no) do not detected by middle Yarn senser 156, after the rotative speed that makes reel spool 24 is reduced to the winding yarn speed rotative speed such for the V3 slower than above-mentioned V1, V2, continue the coiling (S209) of yarns Y to coiling spool 22, and turn back to S201.

In addition, the allowance of holding of the yarns Y in rotation in reserving portion 71 is below A3 and while by Yarn senser 157, yarns Y not detected (S201: no), with other conditional independence, reel spool 24 is stopped the rotation, make thus yarns Y stop the coiling (S210) to coiling spool 22, and turn back to S201.

Next, illustrate when yarns Y in movement disconnects, when yarn faults being detected and use up and the order that connects yarn action etc. of carrying out while changing yarn feeding spool 21 etc. in the yarns Y of yarn feeding spool 21.As shown in Figure 6, when the defect of yarns Y being detected by yarn clearer 15 (S301: be), after by cutter 16 cutting continuous strand Y, removing the part that has defect (S302), carry out the yarn that connects described later and move (S303), and turn back to above-mentioned S301.

In addition, (S301: no when by yarn clearer 15, existing of yarns Y not detected, S304: no), in the situation that the yarns Y of yarn feeding spool 21 remains, that is,, in the situation that yarns Y detected by yarn detector 37, judge into exist (S305: no) that yarns Y do not detected because the yarns Y in movement disconnects by yarn clearer 15, carry out the yarn that connects described later and move (S303), and turn back to S301.

On the other hand, in the situation that the yarns Y of yarn feeding spool 21 is used up,, in the situation that yarns Y (S305: be) do not detected by yarn detector 37, wait for the replacing (S306: no) of yarn feeding spool 21, when having changed yarn feeding spool 21 and the yarns Y of drawing from yarn feeding spool 21 having been detected by yarn detector 37 (S306: be), carry out immediately the yarn that connects described later and move (S303), and turn back to S301.

At this, the order that connects the yarn action in above-mentioned S303 is described.In order to be connect yarn action, at first, by by electromagnetic valve 152 to the open state switching, in the inner space of yarn guide member 73, thread path 128 etc., form from rotate reserving portion 71 sides towards the air stream of yarn guiding tube 26 sides.

In addition, meanwhile, the attraction mouth 26b of upper yarn guiding tube 26 is switched to open state from blocked state, thus, form in upper yarn guiding tube 26 from attracting the air stream of mouthful 26b side towards negative pressure source 120 sides.

Next, make to rotate reserving portion 71 contrary direction low speed rotation when being wound around with yarns Y.Thus, the yarn ends that is present in the yarns Y of rotation on reserving portion 71 is inhaled in the opening of yarn guide member 73, and via thread path 128 etc. from the attraction mouth 26b of yarn guiding tube 26 draw.

And, by drawing sensor 154 while the yarns Y of drawing being detected, after under the state of the low speed rotation to continue rotation reserving portion 71, amount of thread is stipulated in sucking-off, to attract a mouthful 26b to switch and pass through holding part 26c clamping yarns Y from open state to blocked state, and then making yarn guiding tube 26 rotation from the top down centered by axle 26a, the yarns Y that will draw from reservoir 61 thus guides to the yarn feeding device 14 that connects that meets yarn section 8.

On the other hand, yarn under working guiding tube 25 and upper yarn guiding tube 26 similarly, attract to catch the yarn ends of the yarns Y that is present in yarn detector 37 peripheries, and this yarns Y is guided to connecing yarn feeding device 14.Then, after the yarns Y of the yarns Y of reservoir 61 sides and yarn feeder 5 sides is arranged on and connects on yarn feeding device 14, control part 109 makes to connect yarn feeding device 14 and carries out and connect the yarn operation, and the yarns Y that completes yarn feeder 5 sides is moved with the yarn that connects of the yarns Y of reservoir 61 sides.

In addition, there is the disposable unsuccessful situation of yarn operation that connects of carrying out based on connecing yarn feeding device 14, when connecing yarn operation failure, repeatedly repeat and connect the yarn operation.

Next, when as mentioned above, enumerating an example explanation and control rotation reserving portion 71 and reel spool 24 and make winder unit 2 action, the variation of holding allowance of yarns Y from the unwinding yarn speed of yarn feeding spool 21, yarns Y to winding yarn speed and the yarns Y rotation reserving portion 71 of reel spool 24.

As shown in Figure 7, when just starting to reel, due to the yarns Y of rotation in reserving portion 71 to hold allowance fewer than A1, so yarns Y do not detected by upper limit Yarn senser 155.Therefore, rotation reserving portion 71 be take the unwinding yarn speed as the such rotative speed rotation of Vc.In contrast, reel spool 24 be take winding yarn speed as than unwinding yarn speed being the such rotative speed rotation of V2 that Vc is slow.Therefore, the holding allowance according to the difference of unwinding yarn speed Vc and winding yarn speed V2 of yarns Y of rotation in reserving portion 71 and along with the time through increase gradually.

Then, at moment T1, when the holding allowance and surpass A1 of the yarns Y of rotation in reserving portion 71, by upper limit Yarn senser 155, yarns Y detected, reel spool 24 speedups to winding yarn speed is the such rotative speed of V1 faster than unwinding yarn speed Vc.Thus, the allowance of holding of the yarns Y in rotation reserving portion 71 reduces gradually along with the time process.

When the allowance of holding of the yarns Y of rotation in reserving portion 71 is reduced to A1 when following, can't detect yarn by upper limit Yarn senser 155, reel spool 24 is decelerated to winding yarn speed for being the such rotative speed of V2 that Vc is slow than unwinding yarn speed.Thus, the allowance of holding of the yarns Y in rotation reserving portion 71 increases gradually along with the time process.

And, below, the yarns Y of the existence owing to yarn faults being detected by yarn clearer 15 or yarn feeding spool 21 use up or yarn feeding spool 21 and rotation reserving portion 71 between yarns Y disconnect the moment T2 of the existence that can't detect yarn before, reel spool 24 repeats to accelerate and slow down, and the winding yarn speed based on reel spool 24 is alternately switching between V1 and V2.Thus, the allowance of holding of the yarns Y in rotation reserving portion 71 alternately repeats to increase and reduce, and remains on the amount approaching with A1.

Use the action during Fig. 8 further describes above-mentioned moment T1～moment T2.(a) of Fig. 8, (b) are respectively (a) of Fig. 7, the moment T1 of (c) and near the enlarged drawing part between moment T2.But, in order easily to observe accompanying drawing, (a) of Fig. 8, (b) extend the above-mentioned part of Fig. 7 and describe along time-axis directions.

As shown in Figure 8, at moment T1, when by upper limit Yarn senser 155, yarns Y being detected, in the acceleration of the rotative speed of the moment T11 reel spool 24 postponed a little since moment T1, then the acceleration/accel with constant is accelerated, and in moment T12 winding yarn speed, reaches V1.In addition, T11 with respect to the delay of moment T1 is constantly, from yarns Y detected by upper limit Yarn senser 155, to reel spool motor control section 160, makes reel spool motor 116 start the spent time of speedup.And afterwards, reel spool 24, before by upper limit Yarn senser 155, can't detect the moment T13 of yarns Y, be take winding yarn speed as the so constant rotative speed rotation of V1.

Now, in rotation reserving portion 71, the allowance of holding of yarns Y increased before winding yarn speed reaches unwinding yarn speed Vc, after winding yarn speed surpasses unwinding yarn speed Vc, reduced gradually.

Then, at moment T13, when by upper limit Yarn senser 155, can't detect yarns Y, start the deceleration of the rotative speed of reel spool 24 at the moment T14 postponed a little with respect to moment T13, then the acceleration/accel with constant is slowed down, at moment T15, the winding yarn speed that is decelerated to yarns Y is the such rotative speed of V2.In addition, moment T14 is, from can't detect yarns Y by upper limit Yarn senser 155, to reel spool motor control section 160, reel spool motor 116 to be reduced speed now the spent time with respect to the delay of moment T13.And, afterwards, before the moment T17 that reel spool 24 postpones a little at the moment T16 from yarns Y detected by upper limit Yarn senser 155, take winding yarn speed as the so constant rotative speed rotation of V2.

And, by repeating such action, the allowance of holding of the yarns Y in rotation reserving portion 71 repeatedly increases and reduces centered by A1, thus, the allowance of holding of the yarns Y in rotation reserving portion 71 remains on the amount approaching with A1.

Next, at moment T2, when by yarn clearer 15, yarn faults being detected, maybe, when can't detect the existing of yarns Y, rotation reserving portion 71 stops the rotation and makes the unwinding yarn speed is 0.In addition, at moment T2, the allowance of holding of the yarns Y in rotation reserving portion 71 approaches A1, and more than A2, therefore, by Yarn senser 156, yarns Y detected, and reel spool 24, with similarly before this, continues the coiling of yarns Y to coiling spool 22.

Now, because rotation reserving portion 71 stops the rotation, on rotation reserving portion 71, do not hold and stay new yarns Y, so, if continue the coiling amount of yarns Y to coiling spool 22, the allowance of holding of rotating the yarns Y in reserving portion 71 reduces gradually along with the time process.Therefore, rotative speed at reel spool 24 makes the timing that winding yarn speed is V1, in the situation that yarn faults detected or can't detect the existence of yarns Y by yarn clearer 15, reel spool 24 be take winding yarn speed at short notice after the such rotative speed of V1 rotates, and with winding yarn speed, becomes the such rotative speed rotation of V2.On the other hand, rotative speed at reel spool 24 makes the timing that winding yarn speed is V2, in the situation that yarn faults detected or can't detect the existence of yarns Y by yarn clearer 15, reel spool 24 maintains take winding yarn speed and continues rotation as the such rotative speed of V2.

Then, the allowance of holding of the yarns Y in rotation reserving portion 71 reduces gradually along with the time process, at moment T3, when thereby the allowance of holding of yarns Y is while below A2, by Yarn senser 156, can't detect yarns Y, after reel spool 24 is decelerated to the winding yarn speed rotative speed such for the V3 slower than V1, V2, continue the coiling of yarns Y to coiling spool 22.

Then, at moment T4, when connecing the yarn release, rotation reserving portion 71 again starts to rotate and makes the unwinding yarn speed is Vc again.In addition, holding that allowance reduces during moment T2～T4 and be below A1 at moment T4 due to the yarns Y of rotation in reserving portion 71, so can't detect yarns Y by upper limit Yarn senser 155, reel spool 24 be take winding yarn speed as the such rotative speed rotation of V2 (<Vc).

Thus, the yarns Y of rotation in reserving portion 71 hold allowance along with the time through and increase gradually, after the holding allowance and reach A1 of yarns Y, with similarly above-mentioned, winding yarn speed is alternately switching between V1 and V2, and the allowance of holding of yarns Y remains on the amount approaching with A1 thus.

Then, at moment T5, when yarn faults again being detected by yarn clearer 15 or can't detect the existing of yarns Y, with similarly above-mentioned, to stop the rotation and make the unwinding yarn speed be 0 to rotation reserving portion 71, and reel spool 24 be take winding yarn speed and continued the coiling of yarns Y to coiling spool 22 as V1 or the such rotative speed of V2.Then at moment T6, the allowance of holding of the yarns Y in rotation reserving portion 71 is A2 when following, and being decelerated to winding yarn speed is the such rotative speed of V3.

Then, at moment T7, when connecing the yarn release, with similarly above-mentioned, rotation reserving portion 71 again starts to rotate and makes the unwinding yarn speed is Vc again, and reel spool 24 be take winding yarn speed as the such rotative speed rotation of V2 (<Vc).

At this, in the example of Fig. 7, from can't detect yarns Y by yarn clearer 15 for the second time, start to again by yarn clearer 15, the time of yarns Y, i.e. time during T5～T7 constantly being detected, with the primary above-mentioned time, the time during moment T2～T4 is compared elongated.This is because yarns Y stops different from the reason of yarn feeding spool 21 unwindings or connects yarn and move spent asynchronism(-nization) etc. and cause.

Describe particularly, for example, in yarns Y, stop from yarn feeding spool 21 unwindings former because yarn faults detected or because the yarns Y movement disconnects the existence that can't detect yarns Y by yarn clearer 15, and connect in the less situation of the yarn success multiplicity that connects the yarn operation before above-mentioned time shorten.

On the other hand, for example, in the situation that yarns Y stops carrying out because the yarns Y of yarn feeding spool 21 uses up from yarn feeding spool 21 unwindings former the replacing of yarn feeding spool 21 or in the situation that the multiplicity that connects the yarn operation connect before the yarn success is more, above-mentioned time expand.

And, yarns Y after moment T7, in rotation in reserving portion 71 hold allowance more than A2 before, at moment T8, when yarn faults being detected by yarn clearer 15 or can't detect the existing of yarns Y, with similarly above-mentioned, make to rotate that reserving portion 71 stops the rotation and make unwinding yarn speed V is 0.Because the allowance of holding of rotating the yarns Y in reserving portion 71 at moment T8 is below A2, so can't detect yarns Y by middle Yarn senser 156, reel spool 24, after being decelerated to immediately winding yarn speed and being the such rotative speed of V3, continues the coiling of yarns Y to coiling spool 22.

And, then, connect the yarn release, below, same action continued.

According to the 1st embodiment described above, in the situation that yarn faults detected or can't detect the existence of yarns Y by yarn clearer 15, yarns Y in rotation in reserving portion 71 hold allowance less (A2 below) time, make reel spool 24 decelerations and make the winding yarn Speed Reduction.The minimizing of holding allowance of the yarns Y in the rotation reserving portion 71 that therefore, can suppress to be caused to the coiling of coiling spool 22 by yarns Y.Therefore, thereby do not hold under the state that stays new yarns Y on rotation reserving portion 71 even stop unwinding from yarn feeding spool 21 in yarns Y, also can continue for a long time the coiling of yarns Y to coiling spool 22, can guarantee fully the time of being moved for connecing yarn in the situation that do not make to rotate reserving portion 71 maximizations.Perhaps, in the situation that will be guaranteed certain set time in order to connect the yarn action, can make to rotate reserving portion 71 miniaturizations.

In addition, even in the situation that yarn faults detected or can't detect the existence of yarns Y by yarn clearer 15, in the more situation of allowance of holding of the yarns Y in reserving portion 71 in rotation (than A2 many situation), do not reduce the rotative speed of reel spool 24, do not reduce the coiling of yarns Y to the winding yarn speed ground continuation yarns Y of coiling spool 22, so can carry out efficiently the coiling of yarns Y yet.In addition, in this case, because winding yarn speed does not change, so can reduce the waste of power that the variation by winding yarn speed causes.

In addition, yarn faults do not detected by yarn clearer 15 and detecting under the state of existence of yarns Y, yarns Y in rotation in reserving portion 71 hold allowance when more than A1, by making reel spool 24 take winding yarn speed as the rotation of the such rotative speed of the V1 faster than unwinding yarn speed Vc, reduce the allowance of holding of yarns Y in rotation reserving portion 71.On the other hand, the allowance of holding of the yarns Y in rotation in reserving portion 71 is that A1 is when following, by making reel spool 24 take winding yarn speed as being the such rotative speed rotation of V2 that Vc is slow than unwinding yarn speed, increase the allowance of holding of yarns Y in rotation reserving portion 71.Therefore, the allowance of holding of the yarns Y in rotation reserving portion 71 can be remained on to the amount approaching with A1.

At this, as the method for holding allowance of adjusting the yarn in rotation reserving portion 71, different from the 1st embodiment, also can consider to make the winding yarn constant airspeed of yarns Y to coiling spool 22, and the allowance of holding of the yarn in reserving portion 71 changes the rotative speed of rotation reserving portion 71, changes the unwinding yarn speed of yarns Y from yarn feeding spool 21 according to rotation.

But, in the situation that change the unwinding yarn speed of yarns Y from yarn feeding spool 21, and yarns Y to be compared from the situation of yarn feeding spool 21 unwindings with maximum as far as possible unwinding yarn speed Vc, the average unwinding yarn speed of yarns Y slows down.

In addition, in the winder unit 2 of the 1st embodiment, in yarn feeding spool 21, when the unwinding yarn speed that makes yarns Y acutely increases and decreases, existence, because the unfavorable conditions such as knocking over (sloughing) of above-mentioned yarns Y occur in this change, does not therefore expect to make yarns Y acutely to increase and decrease from the unwinding yarn speed of yarn feeding spool 21.When knocking over occurs, due to the broken yarn increased frequency, so cause capacity rating to reduce.

According to above content, in winder unit 2, yarns Y is to the coiling capacity rating of coiling spool 22 in the situation that change the unwinding yarn speed, is starkly lower than the situation that changes winding yarn speed.That is, when change the unwinding yarn speed adjust yarns Y in rotation reserving portion 71 hold allowance the time, can cause yarns Y to become low especially to the coiling capacity rating of coiling spool 22.

Therefore, in the 1st embodiment, from what do one's utmost to avoid acutely to increase and decrease, yarns Y is from the viewpoint of the reduction of the unwinding yarn speed of yarn feeding spool 21, so that the unwinding yarn speed can be normally by yarns Y from the scope of yarn feeding spool 21 unwindings being the mode of maximum Vc, making to rotate reserving portion 71 rotates with constant rotative speed, and the rotative speed that allowance changes reel spool 24 that holds according to the yarns Y in rotation reserving portion 71, change the winding yarn speed of yarns Y to coiling spool 22, adjust thus the allowance of holding of yarns Y in rotation reserving portion 71.Thus, can improve yarns Y in the winder unit 2 coiling capacity rating to coiling spool 22.

In addition, yarns Y in rotation in reserving portion 71 hold allowance when fewer than A3, with other conditional independence, reel spool 24 is stopped the rotation and yarns Y is stopped to the coiling of coiling spool 22, therefore can prevent from holding the yarns Y of staying in rotation reserving portion 71 and use up fully.Thus, for example, can before the yarns Y of rotation reserving portion 71 is used up fully, continue the coiling of yarns Y, thereby can prevent that the yarns Y of reservoir 61 sides for being connect yarn from using up.

The 2nd embodiment

Next, preferred the 2nd embodiment of the present invention is described.The structure of the unwinding yarn reserving portion 209 of the 2nd embodiment is different from the unwinding yarn reserving portion 9 of the 1st embodiment, part in addition is roughly the same structure, therefore, below, the structure of main explanation unwinding yarn reserving portion 209, to the structure identical with the 1st embodiment, suitably description thereof is omitted.

As shown in Figure 9, the unwinding yarn reserving portion 209 of the 2nd embodiment has reservoir 261.Reservoir 261 has 6 rollers 271, base material 272, rotor plate 273, is wound around arm 275, is wound around arm motor 276 etc.

The tabular body that base material 272 is circular, be bearing in the front end of the output shaft 236 that is wound around arm motor 276 via not shown bearing.6 rollers 271 (yarn wound portion) configure along circumference at the upper surface of base material 272, and its lower end pivot suspension is at the upper surface of base material 272, and its upper end is bearing on rotor plate 273.

Rotor plate 273 can be centered by the axis C2 that is wound around arm motor 276 and rotate, and when rotor plate 273 is rotated, the upper end edge that is bearing in the roller 271 on rotor plate 273 is the mobile and mutually the same suitable distance of neutral angle circumferentially.And when by making rotor plate 273 rotate the upper end edge that makes roller 271 while circumferentially moving, roller 271 is to peripheral, oblique.

In addition, be wound around arm motor 276 below be provided with the thread path 244 be communicated with the thread path 228 that is wound around arm 275, below thread path 244, dispose with above-mentioned blow down nozzle 74 (with reference to Fig. 1) identical blow down nozzle 248.

Be provided with and draw sensor 254 in the lower end of blowing down nozzle 248, this draw sensor 254 can detect be rolled into the yarns Y in reservoir 261 yarn ends really to the situation that connects yarn section 8 sides and draw.This is drawn sensor 254 and is electrically connected to control part 109, when the yarn ends that yarns Y detected leads to while connecing yarn section 8 side, to control part 109, sends and draws detection signal.

And, in reservoir 261, as shown in Figure 9, should residing scope set an end (upper end) that is wrapped in winder 6 sides of the yarns Y on roller 271 for scope R2, correspondingly, be provided with the Yarn senser 155～157 identical with the 1st embodiment.And, can by Yarn senser 155～157 detect respectively yarns Y in reservoir 261 whether hold allowance more than A1, A2, A3.

Next, the action of the winder unit of the 2nd embodiment is described.In the 2nd embodiment, also with the 1st embodiment similarly, as shown in Figure 4, Figure 5, yarn faults detected according to whether by yarn clearer 15 and the existence of yarns Y whether detected and the yarns Y in reservoir 261 hold allowance, control the winding yarn speed of yarns Y from the unwinding yarn speed of yarn feeding spool 21 and yarns Y to coiling spool 22 etc., and connect yarn action etc. according to the order identical with Fig. 6.

But, in the 2nd embodiment, as mentioned above, by making to be wound around arm 275 rotations, by yarns Y from 21 unwindings of yarn feeding spool, and by the yarns Y of unwinding so that across roller 271 and around roller 271, the mode of the winding accessory 274 of configuration is wound around.At this, the outer peripheral face that is wound around accessory 274 is wound around auxiliary plane 274a, and with upper section, the mode the closer to the radially inner side of the circumference of configuration roller 271 tilts.And, the yarns Y be wound around be positioned at be wound around on auxiliary plane 274a during, be moved upward and break away from from being wound around auxiliary plane 274a along being wound around auxiliary plane 274a, after becoming the state only be wrapped on roller 271, by the roller 271 be tilted, carrying and be moved upward.Thus, on 6 rollers 271 along axis C2 direction winding yarn Y.

In addition, in the 2nd embodiment, in the S101 of Fig. 4, whether judgement winding arm 275 rotates, and makes to be wound around arm 275 and stop the rotation in S104, makes to be wound around arm 275 and again start rotation in S106.In addition, in the 2nd embodiment, the S303 of Fig. 6 connect yarn the time, draw yarns Y by making to be wound around arm 275 contrary direction rotation to winding yarn Y the time.

Next, illustrate the 1st, the 2nd embodiment is applied to various changes and the variation that obtains.But suitably the description thereof will be omitted to part with structure identical with the 1st, the 2nd embodiment.

In the 1st, the 2nd embodiment, detect and have or not yarns Y by yarn clearer 15, detect thus the movement of the yarns Y between yarn feeder 5 and reservoir 61,261, but be not limited to this.For example, the sensor (speed test section) that speed to mobile yarns Y is detected also can be set between yarn feeder 5 and reservoir 61,261, perhaps, be provided for the sensor (movable length test section) of the length of the mobile yarns Y of detection, detect the movement of yarns Y with these sensors.

When yarns Y normally moves, the speed of the yarns Y detected by the sensor or length are in specialized range, in contrast, when the yarns Y in movement disconnects, while yarns Y being cut off by cutter 16 yarn faults being detected, when the yarns Y of yarn feeding spool 21 is used up etc., speed or the length of the yarns Y detected by the sensor reduce, be finally 0,, break away from the afore mentioned rules scope, the movement that therefore, can whether in specialized range, detect yarns Y according to speed or the length of the yarns Y detected by the sensor.

In addition, in the 1st, the 2nd embodiment, even when by yarn clearer 15, yarn faults being detected or while can't detect the existing of yarns Y, in the situation that yarns Y to hold allowance more than A2, can not reduce winding yarn speed yet, under the state that maintains winding yarn speed before this, continue the coiling of yarns Y to coiling spool 22, but be not limited to this.For example, in a variation (variation 1), what be not provided for detecting yarns Y holds the whether many middle Yarn senser 156 (with reference to Fig. 2) than A2 of allowance, as shown in figure 10, when by cutter 16, yarns Y being cut off (S202: the time), or, when by yarn clearer 15, can't detect yarns Y (S203: no), regardless of the allowance of holding of yarns Y, make without exception the winding yarn Speed Reduction to V3 (S401).

In this case, in yarns Y, stop from the state of the unwinding of yarn feeding spool 21, in the situation that yarns Y to hold allowance more than A2, with the 1st embodiment, compare, the winding efficiency of yarns Y worsens.But, in this case, with the 1st, the situation of the 2nd embodiment compares, in yarns Y, stop, from the state of the unwinding of yarn feeding spool 21, can extending the time that can continue winding yarn Y, and can extending for being connect the time of yarn action etc.Perhaps, in the situation that identical with the 1st, the 2nd embodiment and only will guarantee can be made to rotate reserving portion 71 and the further miniaturization of roller the 271 to the 1, the 2nd embodiment for connecing the time of yarn action.

And, can be also, only when yarn faults (S202: no) not detected and the existing of yarns Y being detected,, only when the normal winding of yarn, carry out the control of winding yarn speed, when yarn faults being detected (S202: be) or while can't detect the existing of yarns Y (S203: no), do not reduce winding yarn speed and continue all the time the coiling of yarns Y with the winding yarn speed with identical before this.But, in this case, although can when the normal winding of yarn, improve the coiling capacity rating of yarn, in order guaranteeing fully for being connect the time of yarn action, need to make to rotate reserving portion 71 and maximize.

In addition, in the 1st, the 2nd embodiment, under the state of the movement that yarn detected, yarns Y in reservoir 61,261 hold allowance when more than A1, make winding yarn speed for being the V1 that Vc is fast than unwinding yarn speed, and be A1 when following in the allowance of holding of yarns Y, make winding yarn speed without exception for being the V2 that Vc is slow than unwinding yarn speed, adjust thus the allowance of holding of yarns Y in reservoir 61,261, but be not limited to this for the control of holding allowance of adjusting yarns Y.

For example, can be also, after the coiling of the yarns Y of carrying out based on winder unit 2 has just started or after connecing just end of yarn, yarns Y in reservoir 61,261 hold allowance when less (such as for A2 when following etc.), make winding yarn speed for the speed slower than V2, after the holding allowance and surpass A2 of yarns Y, making winding yarn speed is V2.Thus, in the situation that the yarns Y in reservoir 61,261 to hold allowance less, the yarns Y that can increase sharply hold allowance.

In addition, replace Yarn senser 155～157, the sensor that holds allowance of the yarns Y of setting in can continuous detecting reservoir 61,261, with detected yarns Y to hold allowance more and the faster mode of winding yarn speed is controlled, also can adjust thus the allowance of holding of yarns Y.

And, can be also, when the normal winding of yarn, not carry out the control of winding yarn speed as described above, only when yarn faults being detected (S202: be) or while can't detect the existing of yarns Y (S203: no), carry out the control of winding yarn speed.But, in this case, although can guarantee fully the time of being moved for connecing yarn in the situation that do not make to rotate reserving portion 71 maximizations, when the normal winding of yarn, need to change the unwinding yarn speed, thereby cause the coiling capacity rating of yarn to reduce.

In addition, in the 1st embodiment, by making to rotate reserving portion 71 rotations, by yarns Y from 21 unwindings of yarn feeding spool, and the yarns Y of unwinding is wound around and hold stay the rotation reserving portion 71 on, in the 2nd embodiment, by making to be wound around arm 275 rotations, yarns Y, from 21 unwindings of yarn feeding spool, and is wound around the yarns Y of unwinding and holds and stay along on a plurality of rollers 271 of circumferential array, but for by yarns Y from the structure of yarn feeding spool 21 unwindings be not limited to this for the structure of holding the yarns Y of staying unwinding.

About for the structure from 21 unwindings of yarn feeding spool by yarns Y, for example, can near yarn feeder 5, wait the application specific architecture different with structure (rotation reserving portion 71, winding arm 275) for winding yarn Y is set.

In addition, about for holding the structure of staying yarns Y, also can make from the yarns Y of yarn feeding spool 21 unwindings by be wound around arm 275 be wrapped in the cylindrical body of self non-rotary substantial cylindrical shape first-class, be wrapped in the parts beyond rotation reserving portion 71 and roller 271 and hold and stay.And, the unwinding yarn reserving portion is not limited to have the structure for the yarn wound portion of winding yarn Y, for example, also can be arranged on inside and be formed with housing for holding the space of staying yarn etc., from the yarns Y of yarn feeding spool 21 unwindings, be directed in this space and hold and stay in this space.

In addition, in the above-described embodiment, in connecing the yarn action, use yarn under working guiding tube 25 and upper yarn guiding tube 26 that the yarns Y of the yarns Y of reservoir side and yarn feeding spool 21 sides is separately positioned on and connects on yarn feeding device 14, but be not limited to this.

In a variation (variation 2), as shown in figure 11, in the 1st embodiment, yarn under working guiding tube 25, upper yarn guiding tube 26 and thread path are not set and form parts 75 etc., replace, be provided with yarn trap setting 301, guide member 302, yarn under working and blow device 303 and yarn trap 304.In addition, in Figure 11, as for supplying with the spool feedway of yarn feeding spool 21, figure is shown with the spool of Sha Kushi and supplies with yarn device 305.

Upper yarn trap setting 301 is configured near the top of the 1st tensioner 41, and is connected with not shown negative pressure source.Guide member 302 is parts cylindraceous roughly, at upper yarn trap setting 301 and the mode of blowing down between nozzle 74 the yarn circuit of the yarns Y when walking around normal winding, extends.In addition, on guide member 302, left end in the drawings is formed with slit 302a in its length range.

Yarn under working blows device 303 and is configured near the below of the 1st tensioner 41.Yarn under working blows device 303 and is connected with not shown pressure air source, produces the air stream towards top.Yarn trap 304 is configured in and connects between yarn feeding device 14 and yarn clearer 15 in the mode that can attract yarns Y, and is connected with not shown negative pressure source.

And, with above-mentioned the 1st embodiment similarly, when yarn in movement disconnects, when yarn faults being detected, use up and while changing yarn feeding spool 21 etc. in the yarns Y of yarn feeding spool 21, if produce air stream in blowing down nozzle 74, the yarn ends that is wrapped in the yarns Y on rotation reserving portion 71 is attracted, and blows to guide member 302 from blowing down nozzle 74.Blow to the yarn ends of guide member 302 as shown in long and short dash line, along the wall on right side in the figure of guide member 302, be directed to the position relative with upper yarn trap setting 301.Upper yarn trap setting 301 by attracting the directed yarn ends of coming by its seizure.And, when by upper yarn trap setting 301, attracting yarn ends, be positioned at guide member 302 the yarns Y stretching and from slit 302a to guide member 302 outside draw, thereby be arranged on, connect on yarn feeding device 14.

On the other hand, yarn under working blows the yarns Y that device 303 blows afloat yarn feeding spool 21 sides upward, and yarn trap 304 attracts and catch by yarn under working to blow the yarn that upper device 303 upwards blows afloat.And, when the yarns Y of yarn feeding spool 21 sides is blown upper device 303 attraction by yarn under working, by stretching, be arranged on and connect on yarn feeding device 14.

And, in variation 2, after as mentioned above the yarns Y of the yarns Y of reservoir 61 sides and yarn feeding spool 21 sides being arranged on and connecing on yarn feeding device 14, with above-mentioned the 1st embodiment similarly, connect yarn in connecing yarn feeding device 14.

In addition, the mode of the yarn circuit of the yarns Y due to guide member 302 when getting around normal winding is extended, so, when normal winding, yarns Y can not come in contact with guide member 302, can prevent that the quality of yarns Y from descending.

In this case, to guide to Yarn guide device 301 from the yarn ends of rotation reserving portion 71 attractions by guide member 302 by blowing down nozzle 74 owing to being configured to, so by change guide member 302 towards, length, shape etc., can more freely change the position relationship of blowing down nozzle 74 and upper Yarn guide device 301.That is, improved the Design freedom of blowing down nozzle 74 and upper Yarn guide device 301.

In addition, in the situation that as mentioned above the yarns Y of the yarns Y of reservoir 61 sides and yarn feeding spool 21 sides is arranged on and connects on yarn feeding device 14, for yarns Y being set connecing on yarn feeding device 14, do not follow the yarn under working guiding tube 25 of the 1st embodiment and the such mechanical action of rotation of upper yarn guiding tube 26, therefore, can yarns Y be arranged on and connect on yarn feeding device 14 rapidly, thus, can shorten until connect the spent time of yarn release.

In addition, in the above-described embodiment, by the groove 27 that traverses is set on reel spool 24, the yarns Y be wound on coiling spool 22 is traversed, but be not limited to this, also can be about to be wound under the state of the yarns Y on coiling spool 22 at hook, the arm-type traverse gear moved back and forth by the left and right, edge carries out traversing of yarns Y.
