As shown in Figure 4, the bottom in the tube portion 78 of reservoir 61 is equipped with via cramp bar and forms tabular cam part 67.Be formed with protuberance 66 on above-mentioned holding part 65, this protuberance 66 contacts above-mentioned cam part 67 and is urged, and thus, holding part 65 constitutes and can switch to the release position from detent position.
In this structure, when downstream yarn guiding tube 26 was positioned at position of readiness, protuberance 66 separated with cam part 67.Then, downstream yarn guiding tube 26 rotates to the device face side from this position of readiness, with its top near the action of yarn 20 roughly side by side, protuberance 66 contact cam part 67, holding part 65 is pushed to the release position side, it is mouthfuls 34 open to attract.In addition, also can adopt at position of readiness and make raised part 66 and above-mentioned cam part 67 attract mouthfuls 34 open structures from beginning at first just to contact, make all the time.
The yarn operation that connects when next, yarn clearer 15 being detected the yarn defect describes.In a single day yarn clearer 15 detects the yarn defect by the supervision of yarn rugosity, just unit controls portion 50 is sent yarn defect detection signals.According to this yarn defect detection signal, the above-mentioned cutter 18 of said units control part 50 operations cuts off yarn 20.Simultaneously, unit controls portion 50 stops the servomotor 55 of reservoir 61, makes thus to hold and stays the rotation of guide arm 75 to stop.Thus, the line end of downstream yarn stops below the entrance hole 80 of reservoir 61.
Then, unit controls portion 50 makes the downstream yarn guiding tube 26 that is maintained at above-mentioned position of readiness turn to the guide position shown in the dotted line of Fig. 2 downwards via catching position.Thus, the part of yarn clearer 15 detected yarn defects, is returned to the upstream side of reservoir 61 by unwinding from reserving portion 71.
So, will be before catching position move at downstream yarn guiding tube 26, the cam part 67 that is configured on the reservoir 61 contacts with the protuberance 66 of holding part 65, attracts mouthful 34 quilts open.Thus, because to attracting near mouthfuls 34 effect that the stream of attraction is arranged, thereby the line end that is in the state that hangs down from entrance hole 80 is attracted mouthfuls 34 and attracts to catch.The action of further rotating, leave catching position with downstream yarn guiding tube 26 roughly side by side, the pushing of 67 pairs of protuberances 66 of cam part is disengaged, holding part 65 returns detent position once more because of the above-mentioned spring that suppresses.At this moment, attract mouthfuls 34, therefore become the state that line end is clamped by the top end part of downstream yarn guiding tube 26 and holding part 65 because the part of line end is inhaled into.
As described above, with downstream yarn guiding tube 26 action by catching position mutually linkedly, holding part 65 carries out switching a series of action of also returning to detent position once more to the release position from detent position.Therefore, the control that downstream yarn guiding tube 26 is stopped at catching position is not to need, and can catch yarn by the moment of catching position apace, the downstream yarn not guided to device of splicer 14 with having stop.In addition, in order to attract to catch reliably, can also to control it is temporarily stopped at catching position.
Clamped the downstream yarn guiding tube 26 of line end, turned to guide position shown in dotted lines in Figure 2, and temporarily stop.Then, upstream side yarn guiding tube 25 attracts to catch the upstream side yarn at position of readiness, and turns to guide position shown in dotted lines in Figure 5.Because this rotation, the upstream side yarn is directed to device of splicer 14.
When the line end of upstream side and the line end in downstream are directed to device of splicer 14 by upstream side yarn guiding tube 25 and downstream yarn guiding tube 26, then begin to connect the yarn operation by device of splicer 14.The thread end that comprises the downstream yarn of yarn defect is cut off by the cutter of device of splicer 14.
The downstream yarn is caused the downstream yarn guiding tube 26 of device of splicer 14, rotating, and return position of readiness around the mode of the rear side of going into device of splicer 14 from the guide position shown in the dotted line of Fig. 2.At this moment, because holding part 65 moves to the release position by the graphic cam part of omission that is configured in device of splicer 14 belows, therefore, the clamping of being undertaken by holding part 65 is disengaged, and cut line end is attracted removal in downstream yarn guiding tube 26.
When device of splicer 14 carried out connect the yarn operation and finish after, do not wait downstream yarn guiding tube 26 to return, just begin yarn 20 once more and stay to holding of reservoir 61 to position of readiness.Consequently, form the mobile route of yarn 20 in the face side of device of splicer 14.Because downstream yarn guiding tube 26 rotates around the mode of going into the rear side to device of splicer 14, the yarn 20 interferences ground that therefore can be not move with face side at device of splicer 14 returns to position of readiness swimmingly.On the other hand, upstream side yarn guiding tube 25 returns to position of readiness through the face side of device of splicer 14 after the upstream side yarn is caused device of splicer 14.
Owing to above-mentioned connect yarn operation and parallel the carrying out of winding work, thereby reel spool 24 is stopped and reversally the yarn defect being removed to the yarn 20 of package 30.After connecing the yarn operation and finishing, the supply to the yarn of reservoir 61 is just changeed, is begun once more in servomotor 55 beginnings.In order to make, will be controlled to be bigger to the feed speed of the yarn 20 of reserving portion 71 than the winding speed of package 30 because of the above-mentioned used up amount of thread of yarn operation that connects recovers.When holding the yarn that has stayed specified amount, unit controls portion 50 makes the feed speed to the yarn of reservoir 61 return to the speed that equates with the yarn winding speed of package 30.
The yarn action that connects during next, to the replacing of yarn feeding spool 21 describes.When above-mentioned yarn detector 37 detects the yarn of supplying with from yarn feeding spool 21 and used up, this yarn detector 37 will not have the yarn detection signal to 50 transmissions of unit controls portion.Receive the unit controls portion 50 of this no yarn detection signal, the supply to the yarn of reservoir 61 is stopped.At this moment, if to regulating, make the opportunity that servomotor 55 is stopped line end stopping at the position of regulation, then the seizure of yarn becomes easily, can further suppress waste of yarns, thereby is preferred.
And, unit controls portion 50 makes downstream yarn guiding tube 26 rotate, near the yarn 20 reservoir 61 inlets is attracted to catch, and, make downstream yarn guiding tube 26 under this state, turn to above-mentioned guide position downwards, thus, the downstream yarn is guided to device of splicer 14.After the downstream yarn was guided to device of splicer 14, downstream yarn guiding tube 26 was around the rear side of going into device of splicer 14, rotate to position of readiness.In addition, because the rotation of this downstream yarn guiding tube 26 is same when detecting with the yarn defect, the Therefore, omited detailed description.
When supplying with new yarn feeding spool 21 by above-mentioned spool feedway, the yarn of yarn feeding spool 21 sides that this is new is directed to device of splicer 14 by upstream side yarn guiding tube 25.And after device of splicer 14 connect yarn with upstream side yarn and downstream yarn, control servomotor 55 made to hold and stays guide arm 75 to hold the direction rotation of staying to yarn 20.
Owing to connect the yarn operation and be and carry out to the winding work of the yarn of package 30 is parallel, so reel spool 24 is stopped and reversing and just can carry out the replacing of yarn feeding spool 21.When connecing the yarn operation and finish, servomotor 55 beginnings are just changeed, and the yarn 20 of new yarn feeding spool 21 is supplied with to reservoir 61.
As shown above, the automatic bobbin winder of present embodiment has coiling portion 9, reservoir 61, device of splicer 14, downstream yarn guiding tube 26.Coiling portion 9 coiling yarns.Reservoir 61 can hold to stay and be wound up into coiling portion 9 yarn before.Device of splicer 14 is for connecing the upstream side that the yarn operation is configured in reservoir 61.Downstream yarn guiding tube 26 is caught the yarn end in device of splicer 14 downstreams and it is guided to device of splicer 14.This downstream yarn guiding tube 26 constitutes, can and the line end that captures be guided between the guide position of device of splicer 14 at the catching position of catching above-mentioned line end and move, and, near this downstream yarn guiding tube 26 standby above-mentioned catching position usually the time.And automatic bobbin winder constitutes, and can catch by 26 pairs of yarns between device of splicer 14 and reservoir 61 of downstream yarn guiding tube of above-mentioned catching position.
Thus, be necessary to connect under the situation of yarn operation, downstream yarn guiding tube 26 can move to catching position at short notice, can begin the seizure of yarn rapidly.Therefore, can shorten the duty cycle that connects the yarn operation, the production efficiency of the package 30 of winder unit 10 productions is improved.Can continue the coiling that undertaken by coiling portion 9 on one side, from reservoir 61 yarn drawn and connect yarn operation on one side.Because to connect the required yarn of yarn operation be not from coiling portion 9 but drawn from reservoir 61, therefore can be as existing design, surface that the package that causes because of pump orifice occurs by pulling the cross winding disorder takes place or generation end face landing in package.Like this, can suppress to connect the yarn operation, maybe this harmful effect is controlled to be zero the harmful effect that the coiling of package 30 causes.And, owing to be to carry out winding work continuously in coiling portion 9, thereby can make the reeling condition of package certain, can form high-quality package.
In the present embodiment, the coiling portion 9 that automatic bobbin winder had constitutes, by the traverse groove 27 of reel spool 24 yarn traversed on one side to reel on one side.Downstream yarn guiding tube 26 has the attraction mouth 34 that is used to attract to catch yarn.Above-mentioned attraction mouth 34 forms with the width littler than the width that traverses of above-mentioned coiling portion 9.
Thus, owing to will not attract mouthfuls 34 as existing pump orifice, constitute the wide cut shape, therefore, can constitute downstream yarn guiding tube 26 compactly in the mode of the whole coiling width that comprises package 30.Owing to can reduce to attract mouth 34, thereby can reduce attraction and catch required pressure, realize energy-conservationization.
In the present embodiment, above-mentioned reservoir 61 has the entrance hole 80 in the path that is used to guide the yarn that is imported into.Above-mentioned catching position is positioned near the entrance hole 80.When connecing the yarn operation, near the yarn of 34 pairs of above-mentioned entrance holes 80 of attraction mouth of downstream yarn guiding tube 26 is caught.
Thus, 80 pairs of entrance holes are imported into the path channeling conduct (restriction) of the yarn 20 of reservoir 61, thereby when connecing the yarn operation, line end are present in the narrow and small zone of below of entrance hole 80 of reservoir 61.Therefore, even small-sized attraction mouth 34 also can easily carry out the seizure of line end, can make and catch the success ratio raising.
The downstream yarn guiding tube 26 that automatic bobbin winder had of present embodiment, as shown in Figure 2, constitute, its top is with near drawing mode around the track of the ring-type of device of splicer 14, being back to above-mentioned catching position or its via above-mentioned guide position from above-mentioned catching position.
Thus, downstream yarn guiding tube 26 can be after guiding to device of splicer 14 with yarn, with around the mode of the rear side of going into device of splicer 14, be back to position when common from guide position.Therefore, connect that yarn mechanism carried out connect yarn after, also can make downstream yarn guiding tube 26 not return position when common with yarn with interfering.
The downstream yarn guiding tube 26 that automatic bobbin winder had of present embodiment, constituting can 360 degree rotation.
Thus, so that the simple structure of downstream yarn guiding tube 26 rotation, can realize not moving near the catching position structure via guide position with yarn from catching position with interfering.
The automatic bobbin winder of present embodiment has the line end of the upstream side that is used to catch device of splicer 14 and it is guided to the upstream side yarn guiding tube 25 of above-mentioned device of splicer 14.
Thus, can promptly catch the line end in downstream and it is guided to device of splicer 14 by downstream yarn guiding tube 26, and, can catch the line end of upstream side and it is guided to device of splicer 14 by upstream side yarn guiding tube 25.Therefore, can promptly connect the yarn operation.
