And, in the 1st embodiment, as described later, in order in above-mentioned scope R1 on rotation reserving portion 71 accumulation yarns Y, the accumulation amount detecting the yarns Y in rotation reserving portion 71 respectively by Yarn senser 155 ~ 157 whether than the scope R1 as above-mentioned accumulation amount upper limit position and the A1 that specifies is many, whether than the scope R1 as above-mentioned accumulation amount half-way and the A2 that specifies is many and whether than the scope R1 as above-mentioned accumulation amount lower position and the A3 that specifies is many.

In addition, the accumulation amount of the yarns Y in the rotation reserving portion 71 that yarns Y accumulation to scope R1 is prescribed a time limit be set to than can maximum accumulation amount that actual accumulation is rotating the yarns Y on reserving portion 71 few, thus, as described later, even if when the accumulation amount rotating the yarn in reserving portion 71 is temporarily many than above-mentioned A1, yarns Y also can not be overflowed from rotation reserving portion 71.

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 (CentralProcessingUnit, central process unit) of arithmetic processing apparatus; The ROM (ReadOnlyMemory, read-only memory (ROM)) of data storing the control program performed by CPU and use in a control program; With the above-mentioned RAM (RandomAccessMemory, random access memory) etc. for the temporary transient storage data when executive routine.And, the above-mentioned control program be stored in ROM is read by CPU and performs on CPU, thus, control program make the hardware such as CPU as reel spool motor control part 160, rotate accumulation drum motor control part 161, draw length of yarn operational part 163, upper pipe control part 164, lower pipe control part 165 and play function.

Reel spool motor control part 160 controls the rotative speed of reel spool motor 116.Rotate hand of rotation and rotative speed that accumulation drum motor control part 161 controls to rotate accumulation drum motor 72.

Draw length of yarn operational part 163 according to from drawing moment that sensor 154 detects yarns Y, the anglec of rotation of rotation accumulation drum motor 72 that detected by rotary encoder 153, carry out computing to as from reservoir 61 to the extraction length of yarn of the length of yarn connecing the yarns Y that side, yarn portion 8 is drawn.

Upper pipe control part 164 compares to the yarn faults length obtained from yarn faults detection signal with by drawing the extraction length of yarn that length of yarn operational part 163 calculates, when drawing length of yarn and reaching yarn faults length, yarn guiding tube 26 is rotated with clamp position, the yarns Y of winder 6 side is guided to yarn splicing device 14, arranges.Lower pipe control part 165 makes yarn under working guiding tube 25 rotate with clamp position, and the yarns Y of yarn feeder 5 side is guided to yarn splicing device 14, arranged.

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 yarn feeding spool 21 unwinding, 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 winding spool 22.The yarn route of the yarns Y in reservoir 61 as shown in Figure 2.That is, operator make yarns Y in order through draw sensor 154, thread path forming member 75 thread path 128, blow down the yarn path 146 of nozzle 74 and the internal path of yarn guide member 73.

In this condition, operator draws yarns Y from the opening relative with rotating reserving portion 71 of yarn guide member 73, it is wound around such as about 5 ~ 20 times on rotation reserving portion 71, and then, rotating in the top-right thread guides 82 of reserving portion 71 through being arranged on to be configured at rotation reserving portion 71 and endless member 81, being then arranged on the 2nd tensioner 42.In addition, for convenience of explanation, in Fig. 2 yarns Y describe comparatively thick and its to be wound around interval also comparatively large, but to have with the wire harness of the yarns Y of the hundreds of circle left and right of little winding apart windings rotating on reserving portion 71 accumulation all the time in reality.

Then, in this condition, rotation accumulation drum motor 72 and reel spool motor 116 is driven.Thus, made the yarns Y unwinding of yarn feeding spool 21 by the rotation rotating reserving portion 71, the yarns Y of unwinding is wrapped on the 71a of tapering.Be wrapped in the yarns Y on the 71a of tapering to move along the surface of tapering 71a to straight flange portion 71c, thus, yarns Y is wrapped in along the axis rotating reserving portion 71 and rotates on reserving portion 71.In addition, make accumulation rotate the yarns Y unwinding on reserving portion 71 by the rotation of reel spool 24, and be wound on the winding spool 22 that rotates together with reel spool 24.That is, in winder unit 2, yarns Y starts winding.And, during carrying out the winding of yarns Y by winder unit 2, rotate the rotative speed etc. of reserving portion 71 and reel spool 24 according to the Row control of Fig. 4 and Fig. 5.

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

And, as shown in Figure 4, under the state rotating reserving portion 71 rotation (S101: yes), when the defect (S102: no) of yarns Y not detected by yarn clearer 15 and existence (S103: yes) of yarns Y detected, namely, when yarns Y mobile being detected, rotation reserving portion 71 is made to continue to rotate in this condition.On the other hand, when the defect of yarns Y being detected by yarn clearer 15 (S102: yes), or when the existing of yarns Y not detected (S103: no), rotation reserving portion 71 being stopped the rotation (S104), and turns back to above-mentioned S101.

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

Next, the action of reel spool 24 is described.As shown in Figure 5, when the accumulation amount rotating the yarns Y in reserving portion 71 is more than A3 (lower limit accumulation amount), namely, when the accumulation of the yarns Y more than regulation lower limit being detected by lower limit Yarn senser 157 (S201: yes), when the defect (S202: no) of yarns Y not detected by yarn clearer 15 and the existing of yarns Y detected (S203: yes), namely, when yarns Y mobile being detected, change the rotative speed of reel spool 24 according to the accumulation amount of the yarns Y rotated in reserving portion 71.

Specifically, when the accumulation of the yarns Y more than set upper limit being detected by upper limit Yarn senser 155, namely, when the accumulation amount rotating the yarns Y in reserving portion 71 is more than A1 (S204: yes), make reel spool 24 with the winding yarn speed of yarns Y for the regulation rotative speed that the V1 faster than unwinding yarns speed i.e. Vc is such rotates, winding spool 22 continues the winding (S205) of yarns Y, and turns back to S201.In addition, in the present invention, winding yarn speed represents the speed being wound into the yarns Y of package by the rotation of reel spool 24.

On the other hand, when yarns Y not detected by upper limit Yarn senser 155, namely, the accumulation amount of the yarns Y in rotation reserving portion 71 is below A1 (S204: no), make reel spool 24 with the winding yarn speed of yarns Y for the regulation rotative speed that the V2 slower than unwinding yarns speed i.e. Vc is such rotates, winding spool 22 continues the winding (S206) of yarns Y, and turns back to S201.

In addition, under the state of the accumulation yarns Y more than regulation lower limit being detected by lower limit Yarn senser 157 (S201: yes), when defect being detected in yarns Y by yarn clearer 15 (S202: yes), or when the existing of yarns Y not detected (S203: no), namely, when the movement of yarns Y not detected and yarns Y detected by Intermediate yarn sensor 156 (S207: yes), because accumulation has the yarns Y of the amount that the accumulation amount of the yarns Y rotated in reserving portion 71 is more than A2, so continue winding (S208) under the state maintaining winding speed.In other words, with the rotative speed identical with when the existing of yarns Y being detected (S203: yes), specifically, when yarn accumulation amount is more than A1 with winding yarn speed be the such rotative speed of V1, when yarn accumulation amount for when below A1 with winding yarn speed for the rotative speed that V2 is such continues the winding of yarns Y to winding spool 22.And, then, turn back to S201.

On the other hand, when the accumulation amount rotating the yarns Y in reserving portion 71 is below A2 and yarns Y is not detected by Intermediate yarn sensor 156 (S206: no), after to be reduced to winding yarn speed making the rotative speed of reel spool 24 be the such rotative speed of the V3 slower than above-mentioned V1, V2, continue the winding (S209) of yarns Y to winding spool 22, and turn back to S201.

In addition, when the accumulation amount rotating the yarns Y in reserving portion 71 is below A3 and yarns Y is not detected by Yarn senser 157 (S201: no), have nothing to do with other conditions, reel spool 24 is stopped the rotation, make yarns Y stopping to the winding (S210) of winding spool 22 thus, and turn back to S201.

Next, the order connecing yarn action etc. of carrying out when illustrating that yarns Y in movement disconnects, when yarn faults being detected and when the yarns Y of yarn feeding spool 21 is used up and changed yarn feeding spool 21 etc.As shown in Figure 6, when the defect of yarns Y being detected by yarn clearer 15 (S301: yes), after removing the part of existing defects (S302), carry out the yarn action (S303) that connects described later by cutter 16 cutting continuous strand Y, and turn back to above-mentioned S301.

In addition, (the S301: no when existing of yarns Y not detected by yarn clearer 15, S304: no), when the yarns Y of yarn feeding spool 21 remains, that is, when yarns Y being detected by yarn detector 37, the existence (S305: no) yarns Y not detected because the yarns Y in movement disconnects by yarn clearer 15 is judged into, carry out described laterly connecing yarn action (S303), and turn back to S301.

On the other hand, when the yarns Y of yarn feeding spool 21 is used up, namely, when yarns Y not detected by yarn detector 37 (S305: yes), 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 detected by yarn detector 37 (S306: yes), carrying out immediately described laterly connecing yarn action (S303), and having turned back to S301.

At this, the order connecing yarn action in above-mentioned S303 is described.In order to carry out connecing yarn action, first, by electromagnetic valve 152 is switched to open state, formed in the inner space of yarn guide member 73, the thread path 128 etc. from rotate reserving portion 71 side towards the air stream of yarn guiding tube 26 side.

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

Next, make rotation reserving portion 71 to direction low speed rotation contrary when being wound around with yarns Y.Thus, the yarn ends being present in the yarns Y rotated on reserving portion 71 is inhaled in the opening of yarn guide member 73, and draws via the suction port 26b of thread path 128 grade from upper yarn guiding tube 26.

And, when the yarns Y of extraction being detected by extraction sensor 154, under the state of the low speed rotation to continue rotation reserving portion 71 after sucking-off regulation amount of thread, suction port 26b is switched from open state to blocked state and passes through holding part 26c and clamp yarns Y, and then yarn guiding tube 26 is rotated from the top down centered by axle 26a, thus the yarns Y of drawing from reservoir 61 is guided to the yarn splicing device 14 meeting yarn portion 8.

On the other hand, yarn under working guiding tube 25, in the same manner as upper yarn guiding tube 26, attracts to catch the yarn ends being present in the yarns Y of yarn detector 37 periphery, and this yarns Y is guided to yarn splicing device 14.Then, the yarns Y of the yarns Y in reservoir 61 side and yarn feeder 5 side is arranged on after in yarn splicing device 14, and control part 109 makes yarn splicing device 14 perform and connects yarn operation, and what complete the yarns Y of yarn feeder 5 side and the yarns Y of reservoir 61 side connects yarn action.

In addition, exist carry out based on yarn splicing device 14 connect the disposable unsuccessful situation of yarn operation, connect yarn operation failure time, repeatedly repeat and connect yarn operation.

Next, as mentioned above, enumerate an example illustrate control to rotate when reserving portion 71 and reel spool 24 make winder unit 2 action, yarns Y from the unwinding yarns speed of yarn feeding spool 21, winding yarn speed from yarns Y to reel spool 24 and rotate the change of accumulation amount of the yarns Y reserving portion 71.

As shown in Figure 7, when just starting to reel, because the accumulation amount rotating the yarns Y in reserving portion 71 is fewer than A1, so yarns Y do not detected by upper limit Yarn senser 155.Therefore, reserving portion 71 is rotated with unwinding yarns speed for the rotative speed that Vc is such rotates.In contrast, reel spool 24 with winding yarn speed for the such rotative speed of the V2 slower than unwinding yarns speed i.e. Vc rotates.Therefore, the accumulation amount rotating the yarns Y in reserving portion 71 according to the difference of unwinding yarns speed Vc and winding yarn speed V2 along with the time is through increasing gradually.

Then, at moment T1, when the accumulation amount rotating the yarns Y in reserving portion 71 is more than A1, yarns Y detected by upper limit Yarn senser 155, reel spool 24 speedup to winding yarn speed is the such rotative speed of the V1 faster than unwinding yarns speed Vc.Thus, the accumulation amount rotating the yarns Y in reserving portion 71 is passed through along with the time and reduces gradually.

When the accumulation amount rotating the yarns Y in reserving portion 71 is reduced to below A1, can't detect yarn by upper limit Yarn senser 155, it is the such rotative speed of the V2 slower than unwinding yarns speed i.e. Vc that reel spool 24 is decelerated to winding yarn speed.Thus, the accumulation amount rotating the yarns Y in reserving portion 71 is passed through along with the time and increases gradually.

And, below, due to detected by yarn clearer 15 existence of yarn faults or the yarns Y of yarn feeding spool 21 use up or before yarn feeding spool 21 and the yarns Y rotated between reserving portion 71 disconnect and can't detect the moment T2 of the existence of yarn, reel spool 24 repeats to accelerate and slow down, and the winding yarn speed based on reel spool 24 alternately switches between V1 and V2.Thus, the accumulation amount rotating the yarns Y in reserving portion 71 alternately repeats to increase and reduce, and remains on the amount close with A1.

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

As shown in Figure 8, at moment T1, when yarns Y being detected by upper limit Yarn senser 155, the acceleration of the rotative speed of reel spool 24 the moment T11 postponed a little from moment T1, then accelerate with the acceleration/accel of constant, reach V1 in moment T12 winding yarn speed.In addition, moment T11 relative to the delay of moment T1 is, from yarns Y being detected by upper limit Yarn senser 155, to the time that reel spool motor control part 160 makes reel spool motor 116 start spent by speedup.And, afterwards, reel spool 24 before the moment T13 that be can't detect yarns Y by upper limit Yarn senser 155, with winding yarn speed for the such constant rotational speeds of V1 rotates.

Now, the accumulation amount rotating yarns Y in reserving portion 71 increased before winding yarn speed reaches unwinding yarns speed Vc, reduced gradually after winding yarn speed exceedes unwinding yarns speed Vc.

Then, at moment T13, when can't detect yarns Y by upper limit Yarn senser 155, the deceleration of the rotative speed of reel spool 24 is started at the moment T14 postponed a little relative to moment T13, then slow down with the acceleration/accel of constant, at moment T15, the winding yarn speed being decelerated to yarns Y is the such rotative speed of V2.In addition, moment T14 relative to the delay of moment T13 is, from can't detect yarns Y by upper limit Yarn senser 155, to reel spool motor control part 160, reel spool motor 116 is reduced speed now the spent time.And, afterwards, reel spool 24 from before the moment T17 that the moment T16 of yarns Y postpones a little detected by upper limit Yarn senser 155, with winding yarn speed for the constant rotational speeds that V2 is such rotates.

And by repeating such action, the accumulation amount rotating the yarns Y in reserving portion 71 repeatedly increases and reduces centered by A1, thus, the accumulation amount rotating the yarns Y in reserving portion 71 remains on the amount close with A1.

Next, at moment T2, when yarn faults being detected by yarn clearer 15, maybe when can't detect the existing of yarns Y, rotating reserving portion 71 and stop the rotation and make unwinding yarns speed be 0.In addition, at moment T2, rotate the accumulation amount of the yarns Y in reserving portion 71 close to A1, and more than A2, therefore, yarns Y detected by Yarn senser 156, reel spool 24, in the same manner as before this, continues the winding of yarns Y to winding spool 22.

Now, because rotation reserving portion 71 stops the rotation, rotating the yarns Y that reserving portion 71 does not have accumulation new, if so continue the winding amount of yarns Y to winding spool 22, then the accumulation amount rotating the yarns Y in reserving portion 71 is passed through along with the time and reduces gradually.Therefore, winding yarn speed is made to be the timing of V1 at the rotative speed of reel spool 24, deposit in case what yarn faults detected by yarn clearer 15 or can't detect yarns Y, reel spool 24 at short notice with winding yarn speed for after the such rotative speed of V1 rotates, the rotative speed becoming V2 such with winding yarn speed rotates.On the other hand, winding yarn speed is made to be the timing of V2 at the rotative speed of reel spool 24, deposit in case what yarn faults detected by yarn clearer 15 or can't detect yarns Y, reel spool 24 maintains with winding yarn speed as the rotative speed that V2 is such continues to rotate.

Then, the accumulation amount rotating the yarns Y in reserving portion 71 is passed through along with the time and reduces gradually, at moment T3, when the accumulation amount of yarns Y is below A2 thus can't detect yarns Y by Yarn senser 156, after to be decelerated to winding yarn speed be the such rotative speed of the V3 slower than V1, V2 at reel spool 24, continue the winding of yarns Y to winding spool 22.

Then, at moment T4, when connecing yarn release, rotating reserving portion 71 and again start to rotate and make unwinding yarns speed be Vc again.In addition, accumulation amount due to the yarns Y in rotation reserving portion 71 reduces and is below A1 at moment T4 during moment T2 ~ T4, so can't detect yarns Y by upper limit Yarn senser 155, reel spool 24 with winding yarn speed for the such rotative speed of V2 (<Vc) rotates.

Thus, the accumulation amount rotating the yarns Y in reserving portion 71 is passed through along with the time and increases gradually, after the accumulation amount of yarns Y reaches A1, as described above, winding yarn speed alternately switches between V1 and V2, and the accumulation amount of yarns Y remains on the amount close 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, as described above, rotate reserving portion 71 stop the rotation and make unwinding yarns speed be 0, reel spool 24 with winding yarn speed for the such rotative speed of V1 or V2 continues the winding of yarns Y to winding spool 22.Then, at moment T6, when the accumulation amount rotating the yarns Y in reserving portion 71 is below A2, being decelerated to winding yarn speed is the such rotative speed of V3.

Then, at moment T7, when connecing yarn release, as described above, rotate reserving portion 71 again start to rotate and make unwinding yarns speed again for Vc, and reel spool 24 with winding yarn speed for the such rotative speed rotation of V2 (<Vc).

At this, in the example of fig. 7, to the time during time, i.e. moment T5 ~ T7 that yarns Y again detected by yarn clearer 15 from second time can't detect yarns Y by yarn clearer 15, elongated compared with the time during primary above-mentioned time, i.e. moment T2 ~ T4.This stops or time of connecing yarn action spent by different from the reason of yarn feeding spool 21 unwinding not cause on an equal basis due to yarns Y.

Be described particularly, such as, stop from the reason of yarn feeding spool 21 unwinding being yarn faults detected by yarn clearer 15 or can't detect the existence of yarns Y because the yarns Y movement disconnects in yarns Y, and connect yarn success before the multiplicity connecing yarn operation less when, above-mentioned time shorten.

On the other hand, such as, when the yarns Y that yarns Y stopping is yarn feeding spool 21 from the reason of yarn feeding spool 21 unwinding uses up the replacing carrying out yarn feeding spool 21 or when connecing the multiplicity connecing yarn operation before yarn success and being more, above-mentioned time expand.

And, after moment T7, before the accumulation amount rotating the yarns Y in reserving portion 71 is more than A2, at moment T8, when yarn faults being detected by yarn clearer 15 or can't detect the existing of yarns Y, as described above, make rotation reserving portion 71 stop the rotation and make unwinding yarns speed V be 0.Because the accumulation amount of the yarns Y rotated in reserving portion 71 at moment T8 is below A2, so can't detect yarns Y by Intermediate yarn sensor 156, reel spool 24, being decelerated to after winding yarn speed is the such rotative speed of V3 immediately, continues the winding of yarns Y to winding spool 22.

And, then, connect yarn release, below, continue same action.

According to the 1st embodiment described above, deposit in case what yarn faults detected by yarn clearer 15 or can't detect yarns Y, when rotating accumulation amount less (below the A2) of the yarns Y in reserving portion 71, reel spool 24 is made to slow down and winding yarn speed is reduced.Therefore, it is possible to suppress by the minimizing of yarns Y to the accumulation amount of the yarns Y in the rotation reserving portion 71 that causes of winding of winding spool 22.Therefore, even if stop unwinding from yarn feeding spool 21 thus under the state rotating the yarns Y that reserving portion 71 does not have accumulation new in yarns Y, also can continuing the winding of yarns Y to winding spool 22 for a long time, the time for carrying out connecing yarn action can being guaranteed when not making rotation reserving portion 71 maximize fully.Or, when certain set time will be guaranteed in order to carry out connecing yarn action, rotation reserving portion 71 miniaturization can be made.

In addition, even if deposit in case what yarn faults detected by yarn clearer 15 or can't detect yarns Y, due in the situation (situations more than A2) that the accumulation amount rotating the yarns Y in reserving portion 71 is more, do not reduce the rotative speed of reel spool 24, namely do not reduce winding yarn speed from yarns Y to winding spool 22 continue the winding of yarns Y, so the winding of yarns Y also can be carried out efficiently.In addition, in this case, because winding yarn speed does not change, so the waste of power caused by the change of winding yarn speed can be reduced.

In addition, yarn faults is not being detected and under the state existence of yarns Y being detected by yarn clearer 15, when the accumulation amount rotating the yarns Y in reserving portion 71 is more than A1, by making reel spool 24 rotate for the rotative speed that the V1 faster than unwinding yarns speed Vc is such with winding yarn speed, reduce the accumulation amount of the yarns Y rotated in reserving portion 71.On the other hand, when the accumulation amount of the yarns Y in rotation reserving portion 71 is below A1, by making reel spool 24 rotate for the rotative speed that the V2 slower than unwinding yarns speed i.e. Vc is such with winding yarn speed, increase the accumulation amount of the yarns Y rotated in reserving portion 71.Therefore, it is possible to the accumulation amount of the yarns Y rotated in reserving portion 71 is remained on the amount close with A1.

At this, the method of the accumulation amount of the yarn in reserving portion 71 is rotated as adjustment, different from the 1st embodiment, also can consider to make yarns Y to the winding yarn constant airspeed of winding spool 22, and change according to the accumulation amount of the yarn rotated in reserving portion 71 rotate reserving portion 71 rotative speed, namely change the unwinding yarns speed of yarns Y from yarn feeding spool 21.

But, when changing yarns Y from the unwinding yarns speed of yarn feeding spool 21, with by yarns Y with unwinding yarns speed Vc maximum as far as possible from compared with the situation of yarn feeding spool 21 unwinding, the average unwinding yarns speed of yarns Y slows down.

In addition, in the winder unit 2 of the 1st embodiment, in yarn feeding spool 21, when making the unwinding yarns speed of yarns Y acutely increase and decrease, there is the unfavorable conditions such as the knocking over (sloughing) that above-mentioned yarns Y occurs due to this variation, therefore undesirably make yarns Y acutely increase and decrease from the unwinding yarns speed of yarn feeding spool 21.When there is knocking over, due to broken yarn increased frequency, so cause capacity rating to reduce.

According to above content, in winder unit 2, yarns Y when changing unwinding yarns speed, is starkly lower than the situation changing winding yarn speed to the winding capacity rating of winding spool 22.That is, when changing unwinding yarns speed and adjusting the accumulation amount of the yarns Y rotated in reserving portion 71, yarns Y can be caused to become low especially to the winding capacity rating of winding 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 view point of the reduction of the unwinding yarns speed of yarn feeding spool 21, to make unwinding yarns speed can normally by yarns Y mode for maximum Vc in the scope of yarn feeding spool 21 unwinding, rotation reserving portion 71 is rotated with constant rotational speeds, and the rotative speed of reel spool 24 is changed according to the accumulation amount of the yarns Y rotated in reserving portion 71, namely the winding yarn speed of yarns Y to winding spool 22 is changed, adjustment rotates the accumulation amount of the yarns Y in reserving portion 71 thus.Thereby, it is possible to improve the winding capacity rating of the yarns Y in winder unit 2 to winding spool 22.

In addition, when the accumulation amount rotating the yarns Y in reserving portion 71 is fewer than A3, have nothing to do with other conditions, reel spool 24 is stopped the rotation and makes yarns Y stopping to the winding of winding spool 22, therefore, it is possible to prevent the yarns Y of accumulation in rotation reserving portion 71 from using up completely.Thus, such as, continue the winding of yarns Y before can using up completely in the yarns Y rotating reserving portion 71, thus can prevent the yarns Y of reservoir 61 side for carrying out connecing yarn from using up.

2nd embodiment

Next, preferred 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 is in addition roughly the same structure, therefore, below, the structure of main explanation unwinding yarn reserving portion 209, suitably omits the description the structure identical with the 1st embodiment.

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, winding arm 275, winding arm motor 276 etc.

Base material 272 is the tabular body of circular, is bearing in the front end of the output shaft 236 of winding arm motor 276 via not shown bearing.6 rollers 271 (yarn wound portion) circumferentially configure 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 rotate centered by the axis C2 of winding arm motor 276, and when making rotor plate 273 rotate, the upper end edge circumference being bearing in the roller 271 on rotor plate 273 moves the distance suitable with mutually the same neutral angle.And when making the upper end edge circumference of roller 271 mobile by making rotor plate 273 rotate, roller 271 is to peripheral, oblique.

In addition, to be configured with rubber ring 281 around the mode of its outer peripheral face on rotor plate 273, as described later, the yarns Y be wrapped on roller 271 is carried to winder 6 through between the gap rotor plate 273 and rubber ring 281.Now, due to yarns Y is carried therebetween with the state be clamped between rotor plate 273 and rubber ring 281, so the fine hair of yarns Y can be made in order.In addition, because yarns Y is clamped between rotor plate 273 and rubber ring 281, so can prevent from producing air ring from roller 271 unwinding in the yarns Y of winder 6 movement.

In addition, in the 2nd embodiment, can be the driving rollers of whole rollers 271 for being rotated by winding arm motor 276, also can be the roller 271 of an only part for driving roller, the driven roller of other rollers for rotating linkedly with the movement of be wound around yarns Y.

Winding arm 275, for yarns Y being guided the bottom of yarns Y to roller 271 from yarn feeding spool 21 unwinding, has in inside and for the thread path 228 of yarns Y movement, can be formed rotatably centered by axis C2.Winding arm 275 links with the outer peripheral face of output shaft 236, is made up of the curve 242 near the line part 241 extended from the outer peripheral face of output shaft 236 to radial outside and the bottom walked around base material 272 and arrive roller 271.

The opening 243 relative with the bottom of roller 271 is formed in the front end of curve 242.In the structure shown here, winding arm 275 can rotate centered by axis C2, by centered by axis C2 under top view left-hand revolution, as described later, the yarns Y being directed into yarn feeder 5 side in the thread path 228 of winding arm 275 is wrapped in the bottom of 6 rollers 271.

Winding arm motor 276 is that such as servomotor, DC brushless motor, stepper motor etc. can the motors of control position, and be electrically connected with control part 109, thus, control part 109 controls rotative speed, the i.e. yarns Y speed of wrap to roller 271 of winding arm 275.

In addition, be provided with the thread path 244 be communicated with the thread path 228 of winding arm 275 in the below of winding arm motor 276, be configured with in the below of thread path 244 with above-mentioned blow down nozzle 74 (with reference to Fig. 1) identical blow down nozzle 248.

Be provided with in the lower end of blowing down nozzle 248 and draw sensor 254, this extraction sensor 254 can detect the yarn ends of the yarns Y be rolled in reservoir 261 really to the situation connecing the extraction of side, yarn portion 8.This extraction sensor 254 is electrically connected with control part 109, when detect the yarn ends of yarns Y lead to connect 8 side, yarn portion time, to control part 109 send draw detection signal.

And, in reservoir 261, as shown in Figure 9, one end (upper end) of winder 6 side of the yarns Y be wrapped on roller 271 residing range set should be become scope R2, correspondingly, the Yarn senser 155 ~ 157 identical with the 1st embodiment is provided with.And, whether manyly than A1, A2, A3 the accumulation amount of the yarns Y in reservoir 261 can be detected respectively by Yarn senser 155 ~ 157.

Next, the action of the winder unit of the 2nd embodiment is described.In the 2nd embodiment, also in a same manner as in the first embodiment, as shown in Figure 4, Figure 5, yarn faults detected according to whether by yarn clearer 15 and the accumulation amount of the yarns Y in the existence of yarns Y and reservoir 261 whether detected, control yarns Y from the unwinding yarns speed of yarn feeding spool 21 and yarns Y to the winding yarn speed etc. of winding spool 22, and carry out connecing yarn action etc. according to the order identical with Fig. 6.

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

In addition, in the 2nd embodiment, in the S101 of Fig. 4, judge whether winding arm 275 rotates, in S104, make winding arm 275 stop the rotation, in S106, make winding arm 275 again start to rotate.In addition, in the 2nd embodiment, Fig. 6 S303 connect yarn time, draw yarns Y by making winding arm 275 rotate to the direction contrary with during winding yarn Y.

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

In the 1st, the 2nd embodiment, detect with or without yarns Y by yarn clearer 15, detect the movement of the yarns Y between yarn feeder 5 and reservoir 61,261 thus, but be not limited thereto.Such as, also can the sensor (speed detecting portion) detected the speed of the yarns Y of movement be set between yarn feeder 5 and reservoir 61,261, or, the sensor (movable length test section) of the length of the yarns Y for detecting movement being set, using these sensors to detect the movement of yarns Y.

When yarns Y normally moves, the speed of the yarns Y detected by the sensor or length are in specialized range, in contrast, when yarns Y in movement disconnects, when 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., the speed of the yarns Y detected by the sensor or length reduce, be finally 0, namely, depart from afore mentioned rules scope, therefore, it is possible to whether be according to the speed of the yarns Y detected by the sensor or length the movement detecting yarns Y in specialized range.

In addition, in the 1st, the 2nd embodiment, even if when yarn faults being detected by yarn clearer 15 or when can't detect the existing of yarns Y, when the accumulation amount of yarns Y is more than A2, also winding yarn speed can not be reduced, under the state maintaining winding yarn speed before this, continue the winding of yarns Y to winding spool 22, but be not limited thereto.Such as, in a variation (variation 1), whether many than the A2 Intermediate yarn sensors of accumulation amount for detecting yarns Y 156 (with reference to Fig. 2) are not set, as shown in Figure 10, when yarns Y being cut off by cutter 16 (S202: time), or when be can't detect yarns Y by yarn clearer 15 (S203: no), regardless of the accumulation amount of yarns Y, make winding yarn speed be reduced to V3 (S401) without exception.

In this case, stop from the state of the unwinding of yarn feeding spool 21 in yarns Y, when the accumulation amount of yarns Y is more than A2, compared with the 1st embodiment, the winding efficiency of yarns Y worsens.But, in this case, compared with the situation of the 1st, the 2nd embodiment, stop from the state of the unwinding of yarn feeding spool 21 in yarns Y, the time can continuing winding yarn Y can be extended, and the time for carrying out connecing yarn action etc. can be extended.Or, when identical with the 1st, the 2nd embodiment and when only will guarantee for carrying out the time connecing yarn action, rotation reserving portion 71 and the further miniaturization of roller the 271 to the 1, the 2nd embodiment can be made.

And, also can be, only when yarn faults (S202: no) not detected and the existing of yarns Y detected, namely, only when the normal winding of yarn, carrying out the control of winding yarn speed, when yarn faults being detected (S202: yes) or when can't detect the existing of yarns Y (S203: no), not reducing winding yarn speed and all the time to continue the winding of yarns Y with winding yarn speed identical before this.But, in this case, although the winding capacity rating of yarn can be improved when the normal winding of yarn, in order to guarantee the time for carrying out connecing yarn action fully, need rotation reserving portion 71 is maximized.

In addition, in the 1st, the 2nd embodiment, under the state of movement yarn being detected, when the accumulation amount of the yarns Y in reservoir 61,261 is more than A1, make winding yarn speed be the V1 faster than unwinding yarns speed i.e. Vc, and when the accumulation amount of yarns Y is below A1, making winding yarn speed is without exception the V2 slower than unwinding yarns speed i.e. Vc, adjust the accumulation amount of the yarns Y in reservoir 61,261 thus, but be not limited thereto for the control of the accumulation amount adjusting yarns Y.

Such as, also can be, after the winding of the yarns Y of carrying out based on winder unit 2 just starts or connecing after yarn just terminates, when the accumulation amount of the yarns Y in reservoir 61,261 is less (when being such as below A2 etc.), winding yarn speed is made to be the speed slower than V2, after the accumulation amount of yarns Y is more than A2, winding yarn speed is made to be V2.Thus, the accumulation amount of the yarns Y in reservoir 61,261 is less, the accumulation amount of the yarns Y that can increase sharply.

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

And, also can be, when the normal winding of yarn, do not carry out the control of winding yarn speed as described above, only when yarn faults being detected (S202: yes) or when can't detect the existing of yarns Y (S203: no), the control of winding yarn speed is carried out.But, in this case, although the time for carrying out connecing yarn action can be guaranteed fully when not making rotation reserving portion 71 maximize, when the normal winding of yarn, need to change unwinding yarns speed, thus cause the winding capacity rating of yarn to reduce.

In addition, in the 1st embodiment, rotate by making rotation reserving portion 71, by yarns Y from yarn feeding spool 21 unwinding, and by the yarns Y of unwinding be wound around and accumulation rotation reserving portion 71 on, in the 2nd embodiment, rotate by making winding arm 275, by yarns Y from yarn feeding spool 21 unwinding, and the yarns Y of unwinding is wound around and accumulation on the multiple rollers 271 circumferentially arranged, but for the structure of yarns Y from the structure of yarn feeding spool 21 unwinding and the yarns Y that is used for accumulation unwinding is not limited thereto.

About for by the structure of yarns Y from yarn feeding spool 21 unwinding, such as, can wait near yarn feeder 5 and the application specific architecture different from the structure (rotating reserving portion 71, winding arm 275) for winding yarn Y is set.

In addition, about the structure for accumulation yarns Y, also can make the cylindrical body being wrapped in self non-rotary substantial cylindrical shape from the yarns Y of yarn feeding spool 21 unwinding by winding arm 275 first-class, be wrapped in accumulation the parts that rotate beyond reserving portion 71 and roller 271.And, unwinding yarn reserving portion is not limited to the structure of the yarn wound portion had for winding yarn Y, such as, also can be arranged on the housing etc. that inside is formed with the space for accumulation yarn, from the yarns Y of yarn feeding spool 21 unwinding to be directed in this space and accumulation in this space.

In addition, in the above-described embodiment, connecing in yarn action, using yarn under working guiding tube 25 and upper yarn guiding tube 26 yarns Y of the yarns Y of reservoir side and yarn feeding spool 21 side to be separately positioned in yarn splicing device 14, but be not limited thereto.

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 forming member 75 etc. are not set, replace, be provided with yarn trap setting 301, guide member 302, yarn under working blow device 303 and yarn trap 304.In addition, in fig. 11, as the spool feedway for supplying yarn feeding spool 21, figure is shown with the spool supply yarn device 305 of Sha Kushi.

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 roughly cylindric parts, and the mode of the yarn circuit of the yarns Y at upper yarn trap setting 301 and when to blow down between nozzle 74 to walk 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 the close beneath that device 303 is configured in the 1st tensioner 41.Yarn under working blows device 303 and is connected with not shown pressure air source, produces air stream upward.Yarn trap 304 is configured between yarn splicing device 14 and yarn clearer 15 can attract the mode of yarns Y, and is connected with not shown negative pressure source.

And, in the same manner as the 1st above-mentioned embodiment, when the yarn in movement disconnects, when yarn faults being detected, when the yarns Y of yarn feeding spool 21 is used up and changed yarn feeding spool 21 etc., if produce air stream blowing down in nozzle 74, the yarn ends being then wrapped in the yarns Y rotated on reserving portion 71 is attracted, and blows to guide member 302 from blowing down nozzle 74.The yarn ends blowing to guide member 302 as indicated by chain dotted lines, is directed to the position relative with upper yarn trap setting 301 along the wall on right side in the figure of guide member 302.Upper yarn trap setting 301 is caught by attracting directed next yarn ends.And when being attracted yarn ends by upper yarn trap setting 301, the yarns Y being positioned at guide member 302 stretches and draws from slit 302a to the outside of guide member 302, thus is arranged in yarn splicing device 14.

On the other hand, yarn under working blows the yarns Y that device 303 blows afloat yarn feeding spool 21 side upward, and yarn trap 304 attracts and catch to be blown by yarn under working the yarn that upper device 303 upwards blows afloat.And, when yarn feeding spool 21 side yarns Y by yarn under working blow upper device 303 attract time, be arranged on by stretching in yarn splicing device 14.

And, in variation 2, be arranged on after in yarn splicing device 14 in the yarns Y by the yarns Y of reservoir 61 side and yarn feeding spool 21 side described above, in the same manner as the 1st above-mentioned embodiment, carry out connecing yarn in yarn splicing device 14.

In addition, due to guide member 302 to get around normal winding time the mode of yarn circuit of yarns Y extend, so when normal winding, yarns Y can not come in contact with guide member 302, can prevent the quality of yarns Y from declining.

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

In addition, when the yarns Y by the yarns Y of reservoir 61 side and yarn feeding spool 21 side described above is arranged in yarn splicing device 14, for in yarn splicing device 14, yarns Y is set, not with the yarn under working guiding tube 25 of the 1st embodiment and the such mechanical action of the rotation of upper yarn guiding tube 26, therefore, rapidly yarns Y can be arranged in yarn splicing device 14, thereby, it is possible to shorten until connect the time spent by yarn release.

In addition, in the above-described embodiment, make to be wound on the yarns Y traversing on winding spool 22 by arranging traversing groove 27 on reel spool 24, but be not limited thereto, under the state that also can be about at hook the yarns Y be wound on winding spool 22, carried out the traversing of yarns Y by the arm-type traverse gear moved back and forth along left and right.
