Like that, cutting part 30 is circular, more specifically is flat truncated cone shape shown in Fig. 5 B.The diameter of the circular blade tip of the cutting part 30 of present embodiment is bigger than the external diameter of bobbin B lower end.The outer peripheral face of bobbin inserting part 29 bottoms has the groove 33 of the ring-type of holding rubber ring 34.Rubber ring 34 has improved the inlay resultant force between bobbin inserting part 29 and the bobbin B.The part of rubber ring 34 from groove 33 outstanding and with the inner peripheral surface butt of bobbin B.
Fig. 4 A and Fig. 4 B show be equipped on ring throstle, the doff doffing device 35 (tube ejector) of mode of known collective.Doffing device 35 has been equipped the bar 36 that doffs that is provided with bobbin grasping device 36a.The transport 37 that is configured in step rail 26 belows has the protruding nail 37a of the empty bobbin B of supporting.Doffing device 35 is with the bobbin B and 38 exchanges of the cop on the spindle 11 of the sky on the protruding nail 37a.When doffing operation, bobbin grasping device 36a pulls up the bobbin B of the sky on the protruding nail 37a, and empty bobbin B is moved along the arrow shown in Fig. 4 A, in the middle of the bobbin B of sky is inserted on the protruding nail 39.Then, bobbin grasping device 36a moves to the top of the cop 38 on the spindle 11.Bobbin grasping device 36a moves along the arrow shown in Fig. 4 B, thereby controls cop 38, cop 38 is pulled up from spindle 11, and cop 38 is inserted on the protruding nail 37a.Then, bobbin grasping device 36a moves along the arrow shown in Fig. 4 A once more, and the bobbin B of the sky on the protruding nail 39 in centre is inserted on the spindle 11.Then, bobbin grasping device 36a moves along the arrow shown in Fig. 4 B, gets back to the position of readiness of protruding nail 37a top.
Below, the effect of present embodiment is described.
Shown in Fig. 5 A like that, but under bobbin B one was installed in state on the spindle 11 rotatably, the bottom of bobbin B and bobbin inserting part 29 were chimeric.When spindle motor 12 makes spindle 11 rotations via tangential belt 15, bobbin B and the rotation of spindle 11 one.
Continue spinning, the result becomes the full packages state, is that pipeline 38 is wound on the state on the bobbin B, the set action that spindle 11 is stopped with filling bobbin B.That is to say that by the action same with prior art, ring rail 17 descends fast, the cop 38 that is installed in the full bobbin state on the spindle 11 is implemented inclination coiling 38a (Figure 1A illustrates).Then, ring rail 17 stops near the abutting part of relative Yarn end cutting parts 28 butts of spindle base portion 24b.Steel traveler T on the ring rail 17 leans on the below slightly than the abutting part of relative Yarn end cutting parts 28 butts of spindle base portion 24b.That is, steel traveler T leans on the below slightly than the abutting part of the lower surface butt of the relative cutting part 30 of spindle base portion 24b.The abutting part of relative Yarn end cutting parts 28 butts of spindle base portion 24b slightly below, spindle 11 is applied braking, spindle 11 stops, and becomes less than one volume of having reeled, the state of the yarn about 1/2 volume for example.Lappet 18 is not configured to can give the retreating position that doffs and counteract.State shown in Figure 1A appears in its result.
In other words, when stopping to doff, ring rail 17 stops at the corresponding position of abutting part of relative Yarn end cutting parts 28 butts with spindle base portion 24b.At this, said " the corresponding positions of abutting part of relative Yarn end cutting parts 28 butts with spindle base portion 24b " are meant following position, this position makes when ring rail 17 is present in this position under the state of Yarn end cutting parts 28 and spindle base portion 24b butt, can will import between cutting part 30 and the spindle base portion 24b to the yarns Y of cop 38 continuously from steel traveler T.
Then, make doffing device 35 actions.The cop 38 that bobbin grasping device 36a will expire the bobbin state pulls up from spindle 11.Lift motor 23 rises ring rail 17.Lift motor 23 makes ring rail 17 rise with the speed identical with the speed that pulls up of cop 38.Up to cop 38 pull up from spindle 11 midway till, Yarn end cutting parts 28 all together rise with cop 38.Shown in Figure 1B, like that, be directed between Yarn end cutting parts 28 and the spindle base portion 24b from cop 38 continuous yarns Y to steel traveler T.
As described above, when spindle 11 pulls up cop 38, ring rail 17 is risen.Thereby, rising to from position shown in Figure 1A shown in Figure 1B during the position at cop 38, the increase of tension force that is connected to the yarns Y of steel traveler T from cop 38 is suppressed.Its result, like that, even cop 38 rises, the position of the relative rings 17a of steel traveler T does not change yet shown in Fig. 1 C and Fig. 1 D.Fig. 1 C and Fig. 1 D have demonstrated the state different with the steel traveler 56 of expression Fig. 6 E of prior art and Fig. 6 F.Like this, in the present embodiment, the winding angle that yarns Y is reeled on spindle 11 can not diminish.Its result, Yarn end cutting parts 28 are when breaking away from the position that moves to spindle base portion 24b butt from cop 38, and 28 leakages of Yarn end cutting parts take place, and to control the probability of yarns Y lower.
The easy degree that steel traveler T moves is influenced by spinning conditions such as the rugosity of institute's yarn and the twist.When institute's yarn was thin, employed steel traveler T was light, and steel traveler T moves easily.Therefore, compare with the situation of spinning 40 yarn, under the situation of spinning 80 count yarns thinner than 40, even the tension force recruitment of yarns Y is identical, steel traveler T also moves than being easier to.In addition, when the yarns Y with kink (snarl) was applied tension force, yarns Y broke away from from steel traveler T easily, and perhaps yarns Y significantly moves.Therefore, according to spinning conditions, the tension force of cop 38 yarns Y when spindle 11 pulls up is increased the feasible value difference of ratio.In the present embodiment, when spindle 11 pulled up, ring rail 17 rose simultaneously and with identical speed with cop 38 with cop 38.Like this, the tension force increase of yarns Y is suppressed to minimum.
Ceiling (limit of rising) to ring rail 17 is set, and makes that steel traveler T is positioned at below the upper surface of cutting part 30 when cutting part 30 rises the most.In the present embodiment, as benchmark, the ceiling of ring rail 17 is set with state cutting part 30 upper surfaces down of Yarn end cutting parts 28 and spindle base portion 24b butt, make steel traveler T be positioned at than this benchmark lean on last 10mm with scope.Specifically, the ceiling of ring rail 17 is set, made steel traveler T be positioned at 5mm place, benchmark top.The position of the steel traveler T corresponding with the ceiling of ring rail 17 is corresponding to half position of the maximum open amount of Yarn end cutting parts 28.Said " the maximum open amounts of Yarn end cutting parts 28 " are meant, the largest interval distance between cutting part 30 and the spindle base portion 24b.
When the Yarn end cutting parts 28 that together rise with cop 38 both reached take the altitude, the active force of helical spring 31 made Yarn end cutting parts 28 break away from from cop 38.Like this, Yarn end cutting parts 28 descend, with spindle base portion 24b butt.Yarn end cutting parts 28 are controlled (clamping) from cop 38 continuous yarns Y to steel traveler T with spindle base portion 24b.Cop 38 continues to rise.Thereby cutting part 30 is crimped on yarns Y under the tensioning state, and the result cuts off yarns Y.So, become the state shown in Fig. 2 A.Yarn end cutting parts 28 and spindle base portion 24b control the yarns Y after (clamping) cut-out.Yarns Y via steel traveler T and twizzle 18a, arrives front roller 40 shown in Figure 3 from Yarn end cutting parts 28 and spindle base portion 24b.
After cop 38 is doffed, become the state shown in Fig. 2 B.Empty bobbin B is inserted on the spindle 11.Lappet 18 is configured to winding position.Then, start the machine once more.Till doffing next time, Yarn end cutting parts 28 and spindle base portion 24b continue to control (clamping) continuously to the end of the yarns Y of steel traveler T.Control the yarn tail of (clamping) by Yarn end cutting parts 28 and spindle base portion 24b, when doffing, link to each other disengaging spindle 11 next time with cop 38.
Present embodiment has following such advantage.
(1) the Yarn end cutting parts 28 that possess cutting part 30 rise with cop 38 when doffing, and then descend.Its result, Yarn end cutting parts 28 are controlled (clamping) from cop 38 continuous yarns Y to steel traveler T with spindle base portion 24b.Cutting part 30 cuts off yarns Y.Therefore, present embodiment is different with the prior art of the yarn tail being controlled by the yarn tail is wound to spindle 53.That is to say that present embodiment need not yarn mantissa time is wound on the spindle 11.And present embodiment need not form special yarn tail coiling portion, only just can reduce the yarn (yarn tail) that residues in spindle base portion 24b by simple structure.
(2) doffing device 35 with cop 38 when spindle 11 pulls up, ring rail 17 also rises.Thereby, with cop 38 when spindle 11 pulls up, from cop 38 via steel traveler T and twizzle 18a and the stretch-draw that is connected to the yarns Y of front roller 40 be suppressed.Its result, the mobile of steel traveler T is suppressed.Therefore, Yarn end cutting parts 28 break away from from the cop 38 that rises midway, when turning back to the position with spindle base portion 24b butt, leak the probability of controlling (controlling ミ ス) to the yarns Y of steel traveler T by Yarn end cutting parts 28 continuously from cop 38 and reduce.And, compared with prior art, reduced the yarn leakage and cut (cutting れ ミ ス).
(3) with cop 38 when spindle 11 pulls up, the tension force that is connected to the yarns Y of twizzle 18a from cop 38 via steel traveler T increases.In the present embodiment, the rate of climb of ring rail 17 be set at cop 38 to pull up speed identical.Therefore, the tension force of yarns Y increases minimum.Like this, Yarn end cutting parts 28 leak the situation of controlling yarns Y and further are inhibited.
(4) ceiling of ring rail 17 is configured to, below cutting part 30 upper surfaces when making steel traveler T be positioned at cutting part 30 to rise the most.If under steel traveler T is present in than the also high locational state of the upper surface of cutting part 30, in other words be exactly under the state that steel traveler T deflects away from from (peristome) between the lower surface of Yarn end cutting parts 28 and the spindle base portion 24b, Yarn end cutting parts 28 break away from from cop 38, then leak the probability of controlling yarns Y and increase.Yet, in the present embodiment, be under steel traveler T must be present in state between Yarn end cutting parts 28 lower surfaces and the spindle base portion 24b, Yarn end cutting parts 28 break away from from cop 38.Like this, further reduce Yarn end cutting parts 28 and leaked the possibility of controlling yarns Y.
(5) on spindle 11, dispose the helical spring 31 that works as the limiting part that limits 28 risings of Yarn end cutting parts.This helical spring 31 has been set the maximum ceiling of cutting part 30.Therefore, can set the maximum ceiling of cutting part 30 simply, its result, the setting of ring rail 17 ceilings also becomes easy.
(6) with the upper surface of the cutting part 30 under the state of Yarn end cutting parts 28 and spindle base portion 24b butt as benchmark.The ceiling of ring rail 17 is configured to, make steel traveler T be positioned at than this benchmark by top 10mm with scope.If the lifting position of steel traveler T too away from the abutting part of relative Yarn end cutting parts 28 butts of spindle base portion 24b, then exists Yarn end cutting parts 28 to leak the danger of controlling yarns Y easily.Yet in the present embodiment, this possibility is very little.
(7) ceiling of ring rail 17 is set, made half the position of steel traveler T corresponding to the maximum open amount of Yarn end cutting parts 28.If with the ceiling of setting ring rail 17, make steel traveler T compare corresponding near the situation the Yarn end cutting parts 28 maximum open amount upper limits, yarns Y is controlled in then more difficult in the present embodiment leakage.
(8) helical spring 31 always towards spindle base portion 24b to Yarn end cutting parts 28 application of forces.Thereby, can control continuous yarns Y reliably with the Yarn end cutting parts 28 of spindle base portion 24b butt to steel traveler T.
Embodiments of the present invention are not limited to aforesaid way, also can be as following specific implementation.
Yet, preferably the ceiling of ring rail 17 is set for, below cutting part 30 upper surfaces when making steel traveler T be positioned at cutting part 30 to rise the most.This be because, if at steel traveler T under than the also high locational state of cutting part 30 upper surfaces, promptly under the state that steel traveler T deflects away from from the peristome between Yarn end cutting parts 28 and the spindle base portion 24b, Yarn end cutting parts 28 break away from from cop 38, and then Yarn end cutting parts 28 leak the probability of controlling yarns Y and increase.Yet,,, also can reduce Yarn end cutting parts 28 sometimes and leak the situation of controlling yarns Y even under the situation that steel traveler T deflects away from from the peristome between Yarn end cutting parts 28 and the spindle base portion 24b according to spinning conditions such as the rugosity of yarn, the twists.
Also can be with cutting part 30 upper surfaces under the state of Yarn end cutting parts 28 and spindle base portion 24b butt as benchmark, doffing device 35 is set cop 38 ceiling of ring rail 17 when spindle 11 pulls up, make steel traveler T be positioned at than this benchmark by the position more than the last 10mm.Yet, preferably the ceiling of ring rail 17 is set for, make steel traveler T be positioned at than said reference by last 10mm with scope.This is because when the lifting position of steel traveler T during too away from the abutting part of spindle base portion 24b and Yarn end cutting parts 28 butts, Yarn end cutting parts 28 leak the danger increase of controlling yarns Y.If make the lifting position of steel traveler T be positioned at than said reference by last 10mm with, even then under the situation that spinning conditions changes, it is also very little that such yarn leaks the possibility of controlling.
, be not limited to begin simultaneously from pulling up of spindle 11 with the opportunity that cop 38 makes ring rail 17 begin to rise when spindle 11 pulls up at doffing device 35 with cop 38.For example, also can make the rising of ring rail 17 begin to be later than cop 38 pulling up from spindle 11.Yet, the rising beginning of ring rail 17 and cop 38 are carried out simultaneously from the beginning that pulls up of spindle 11, the tension force that can suppress yarns Y increases, so preferred.
Parts as the restriction portion of restriction Yarn end cutting parts 28 risings works are not limited to be configured in the helical spring 31 between the collar 32 and the Yarn end cutting parts 28.For example, also can save the helical spring 31 and the collar 32, but in the set fixed-site of spindle blade 24a by limiting the retainer that Yarn end cutting parts 28 rise with bobbin inserting part 29 butts.Yarn end cutting parts 28 in the process that cop 38 rises can be by breaking away from from cop 38 with above-mentioned retainer butt.
Cutting part 30 is not limited to circle, also can be zigzag.In addition, also can adopt following structure: circular sword body is set as split with respect to the cutting part body, the sword body is fixed on the portion of connecting airtight on the body and body possesses a plurality of being used for.
