The yarn guiding part of after the leading section of the arm 74 that traverses is formed with, stating 73.The arm 74 that traverses can keep (guiding) yarn 20 through yarn guiding part 73.Because yarn guiding part 73 carries out crankmotion under the state that is keeping yarn 20, so yarn 20 is traversed.
Below, the warpage in the yarn road that produces when yarn 20 is traversed describes.
In Fig. 3 as the lateral plan of traverse gear 70; The rotation axis (rotation axis of the arm 74 that traverses) of drive motor 76 of traversing is represented with symbol L1, representes with symbol L2 along the straight imaginary line of drawing of length direction (line of centers in the side of the arm 74 that traverses) the side of the arm 74 that traverses from the base end part of the arm 74 that traverses.Along with the crankmotion of the arm 74 that traverses, yarn guiding part 73 is with the mode of in the imaginary plane perpendicular to the rotation axis L1 of the arm 74 that traverses, drawing circular-arc track move back and forth (following this imaginary plane is called " plane of revolution ").In this embodiment, the arm 74 that traverses generally perpendicularly disposes with respect to rotation axis L1.Thus, said imaginary line L2 is vertical with respect to rotation axis L1.Therefore, we can say that the arm 74 that traverses carries out crankmotion in said plane of revolution.
Yarn diatom L3 is near the traverse straight line in the yarn road leading section of arm 74 (from the end of guide plate 28 to the yarn road of contact roller 29) of expression.In this embodiment, this yarn diatom L3 is parallel with the rotation axis L1 of the arm 74 that traverses.In other words, yarn diatom L3 is vertical with said plane of revolution (and imaginary line L2).
In addition, about yarn diatom L3, except said method, can also be expressed as " will with the situation of position that is positioned at upstream side in the yarn 20 of contact roller 29 contact as a P1 under is connected this P1 and the straight line of the fulcrum 27 of traversing ".In addition, this P1 also can show as " expression is by yarn 20 beginnings of yarn guiding part 73 guiding and the point at the position that contacts roller 29 contacts ".
Therefore, though thereby yarn guiding part 73 is that the mode of the circular-arc track at center moves back and forth yarn 20 is traversed to draw with rotation axis L1,, the power on the yarn 20 of being applied to this moment is on the above-mentioned direction parallel with plane of revolution.That is to say, owing to applying yarn 20 is gone up by the power that pulls or relax in the direction (along the direction in yarn road) of yarn diatom L3, so can be alleviated the warpage in yarn road at the Shi Buhui that traverses.Particularly in this embodiment, because at the place, end of traversing, the mode that is positioned on the yarn diatom L3 with the guide point of yarn guiding part 73 disposes the arm 74 that traverses, so the warpage in yarn road that can make the place, end of traversing is for minimum.In addition, suppose that rotation axis L1 and yarn diatom L3 are not parallel, the yarn 20 in then traversing not only on the direction in plane of revolution, also stressed on the direction of yarn diatom L3.Therefore, the warpage in yarn road is bigger than this embodiment.In this case, the winding tension that is wound on the yarn 20 in the package 30 can rise, or the hardness of package 30 especially can rise in the package end, and skips perhaps take place.Consequently.The quality of package 30 reduces.
In addition, as shown in Figure 3, the arm 74 that traverses has to joggling part (kink) 72a near the direction bending that contacts roller 29.In addition, though joggling part 72a is the structure that bends (bending) with steep anxious angle, also can be the structure of slick and sly bending (bending).
Through this structure; Make yarn guiding part 73 near package 30 and the contact wire that contacts roller 29, thus can shorten drift (from traverse arm 74 to the length of the yarn 20 that contacts roller 29 contact) and impression length (print length) (with the length that contacts roller 29 contiguous yarns 20).Therefore, owing to can make the action of the yarn 20 of being reeled stable, so can improve the quality of package 30.
In addition, under the situation of the package 30 of passing through doff unit 10 coiling cone shapes, especially hope to adopt the arm 74 that traverses, give reasons below with joggling part 72a.That is, the coiling from package 30 begin to become to thread layers big during, on the coiling spool 22 (package 30) of the contact roller 29 of drum (cylindrical shape) and cone shape, difference is big.Consequently, with respect to the central portion of the coiling Width of package 30, in larger diameter side, winding tension is high, and in smaller diameter side, winding tension is low.Therefore, in the end of package 30 skips or package wrinkle taking place easily, forms bad package.About this point; The traverse arm 74 with joggling part 72a such through this embodiment traverses yarn 20; Can in the drift of the yarn 20 that shortens package end (end of traversing) and impression length, the warpage of yarn 20 also be alleviated thus, thereby can prevent to form the bad package of above-mentioned that kind.
Below, the position relation of the last yarn in the yarn ends seizure being caught the parts 26 and the arm 74 that traverses describes.In addition, in Fig. 3, illustrated yarn ends in catching on yarn catch the position of parts 26.
As shown in Figure 3, the leading section (yarn guiding part 73) of the arm 74 that traverses of this embodiment is configured near (below and the face side of contact roller 29) of contact roller 29.This is in order to shorten drift and impression length.Through such shortening drift and impression length, can make the action of the yarn 20 in the coiling stable, thereby can improve the quality of package 30.
The arm 74 that traverses is configured such that yarn guiding part 73 is configured on the yarn diatom L3, and arm 72 is configured in from the position that yarn diatom L3 keeps out of the way.Specifically, yarn guiding part 73 is arranged on the face side of doff unit 10, and arm 72 is arranged on the inboard of doff unit 10.Therefore, the last yarn seizure parts 26 during the arm 74 that traverses in traversing is caught with yarn ends can not interfered.Consequently, the arm 74 that can positively prevent to traverse is caught conflicting of parts 26 with last yarn.Therefore, turn near the package 30 owing to can after the cut-out of Yarn break and yarn occurring, make yarn catch parts 26 immediately, thus the yarn action can be connect as soon as possible, and the coiling action that can promptly begin package 30 once more.
In addition; Suppose in this embodiment the structure that adopts the arm 74 that traverses to dispose with mode along yarn diatom L3; Before then near last yarn seizure parts 26 turn to package 30, yarn guiding part 73 is moved to exceed the retreating position of the end of traversing (going up the width that yarn attracts mouth 35).Its reason is, the last yarn that last yarn is caught parts 26 attracts mouthfuls 35 part conflict with yarn guiding part 73, thus yarn guiding part 73 meeting breakages.Therefore, need by on yarn catch parts 26 and carry out making yarn guiding part 73 temporarily move to above-mentioned retreating position before the seizure of yarn ends, and undertaken by device of splicer 14 connect the yarn end of job after yarn guiding part 73 is moved in the scope of traversing.But,, can omit the mobile control of catching the cooresponding yarn guiding part 73 of action of parts 26 with the last yarn of above-mentioned that kind through as this embodiment, disposing the arm 74 that traverses.
In addition; If hypothesis adopts the traverse gear (traverse gear of for example said patent documentation 1) traverse arm with respect to the structure that face is set on vertical direction roughly, extends in this embodiment; Then as preventing the method for conflicting of yarn attraction mouth 35 with the arm that traverses, consideration is configured in this arm that traverses the upstream side (with to a certain degree away from the contact roller) in yarn road.But in such layout, drift is elongated.Consequently, it is unstable that the action of yarn 20 becomes, so the quality of package 30 reduces, or yarn 20 is hooked on periphery material etc. and goes up and cause the coiling action of package 30 to continue.About this point, as shown in Figure 3 when the direction of principal axis of contact roller 29 is observed in this embodiment, the arm 74 that traverses is to oblique upper (in other words, roughly the tangential direction at package 30 and the contact wire place that contacts roller 29 in the lateral plan) extension.That is to say that the imaginary line L2 of the arm 74 that traverses sets towards the top bevelled mode of doff unit 10 with respect to the setting of doff unit 10 with yarn guiding part 73 sides.Contact roller 29 is positioned between the leading section (yarn guiding part 73) and package 30 of the arm 74 that traverses.Thus, on one side can keep the drift of the weak point of yarn 20, catch the interference of parts 26 and yarn guiding part 73 Yi Bian easily prevent the last yarn in the yarn ends seizure.In addition, preferably the traverse imaginary line L2 of arm 74 is configured at 0 degree (parallel state) in the scope of 60 degree with respect to the face that is provided with of doff unit 10.
In addition, will traverse arm 74 to dispose with respect to the mode of face towards oblique upper is set through above-mentioned that kind, the base end part that can make the arm 74 that traverses is significantly away from the path of yarn 20.Therefore, the structure of yarn road periphery (the last yarn that rotates is up and down caught parts 26 etc.) is not easy to interfere with the base end part of the arm 74 that traverses.Particularly owing in this embodiment, directly link the drive motor 76 that traverses at the base end part of the arm 74 that traverses, so traverse drive motor 76 also can away from the path of yarn 20 be configured.Consequently, the degree of freedom of the layout of doff unit 10 is good.
Below, with reference to Fig. 4 the yarn guiding part 73 that the arm 74 that traverses is had is described.The arm 74 that traverses is made up of the yarn guiding part that is configured in front 73, the arm 72 that is configured in base end side.
Yarn guiding part 73 is constituted hook-shaped by pottery and aluminium etc., and is connected the front of arm 72.As shown in Figure 4, yarn guiding part 73 is formed to the bent shape of a lateral bending.Be formed with in interior all sides of yarn guiding part 73 and be used to collude the elongated yarn that tangles yarn 20 and collude hanging groove (yarnhooking groove) 71.Yarn collude hanging groove 71 with the sidepiece in a side of yarn guiding part 73 form opening portion (guiding port) 71b and along the length direction of the arm 74 that traverses forward the mode of distolateral straight extension form.Terminal part (restrictions) 71a that yarn colludes hanging groove 71 is close-shaped (front of the arm 74 that traverses is not open).Yarn colludes the end (said opening portion 71b) of the open sides of hanging groove 71 and compares the base end side that is positioned at the arm 74 that traverses with the end that becomes the terminal (said terminal part 71a).
Thereby when on one side through yarn guiding part 73 guiding yarns 20 yarn 20 being traversed yarn 20 is wound on 30 last times of package, yarn 20 is positioned at the inside that yarn colludes hanging groove 71.Along with moving back and forth of yarn guiding part 73, the internal face that yarn colludes hanging groove 71 promotes yarn 20, and yarn 20 is traversed with respect to package 30.In addition, in this embodiment, the opening portion 71b that yarn colludes hanging groove 71 is not towards the front of the arm 74 that traverses but towards base end side.Therefore, even there is the masterpiece towards the front of the arm 74 that traverses to be used on the yarn 20, yarn 20 can not deviate from from yarn guiding part 73 yet.
Sidepiece at yarn guiding part 73 is formed with two rake 73a and 73b.Rake 73a extends in the bevelled direction towards the opening portion 71b that yarn colludes hanging groove 71 from the leading section of the bending of yarn guiding part 73.Rake 73b from the base end part (with the connecting bridge of arm 72) of yarn guiding part 73 towards the opening portion near the diagonally extending of 71b.Therefore; Under the state after the package of package 30 begins and just carried out connecing the yarn operation, that yarn 20 is deviate from from the arm 74 that traverses; The arm 74 that traverses is rotated to a side that is formed with rake 73a and 73b (left side of Fig. 4); Rake 73a and 73b contact with yarn 20 thus, under the guiding function of rake 73a and 73b, can make yarn 20 enter into yarn from opening portion 71b and collude in the hanging groove 71.
As discussed above, the automatic bobbin winder 1 of this embodiment comprises yarn feeder 11, reel cage 23, contact roller 29, the arm 74 that traverses, the drive motor 76 that traverses, device of splicer 14, goes up yarn seizure parts 26.Yarn feeder 11 is supplied with the yarn 20 that will reel to package 30.The coiling spool 22 of coiling yarn 20 supports with the mode that can rotate in order to form package 30 for 23 pairs of reel cages.Contact roller 29 contacts with coiling spool 22 or package 30 and rotates.Front at the arm 74 that traverses disposes the yarn guiding part 73 that is used to guide yarn 20.The arm 74 that traverses traverses yarn 20.76 pairs of the drive motor that the traverse arm 74 that traverses is rotated driving.Device of splicer 14 links the yarn ends of package 30 sides and the yarn ends of yarn feeder 11 sides.Last yarn seizure parts 26 can be caught the yarn ends of package 30 sides and guided to device of splicer 14.When the direction of principal axis of contact roller 29 is observed, near the yarn diatom L3 in the yarn road that the yarn guiding part at the place, end that the rotation axis L1 of the arm 74 that traverses and expression are traversed 73 is is parallel.
Thus, because rotation axis L1 is parallel with yarn diatom L3, so even when the arm 74 that traverses rotates to the end, yarn guiding part 73 is also moving on the direction of yarn diatom L3 hardly.Therefore, owing to can the warpage of yarn 20 be suppressed at Min., reduce so can prevent the quality of package 30.In addition, because the base end part of the arm 74 that traverses is left from the path of yarn 20 significantly, can easily can realize avoiding traversing the base end part of arm 74 and the layout that contacts of last yarn seizure parts 26 grades.
In the automatic bobbin winder 1 of this embodiment, last yarn catches that parts 26 have that yarn ends to package 30 sides attracts and the last yarn of catching attracts mouthfuls 35 to go up the last yarn tube arm 36 of yarn attraction mouth 35 with supporting.Last yarn attract the yarn ends of mouthful 35 pairs of package sides to attract and location of capture on, traverse arm 74 with yarn guiding part 73 and last yarn attract mouthfuls 35 compare the upstream side that is positioned at the yarn road mode be bearing on the drive motor 76 that traverses (output shaft 77).
Thus, can prevent positively that yarn guiding part 73 and last yarn from attracting mouth 35 to contact and breakage.In addition, not need by on yarn catch in the capturing motion of the yarn ends that parts 26 carry out the arm 74 that traverses moved to special retreating position.Therefore, for example through on yarn catch after parts 26 catch the yarn ends of packages 30 sides and carried out the suitable processing based on device of splicer 14 etc., can begin the winding work of yarn 20 as soon as possible once more.In addition; Through the arm 74 that traverses yarn 20 is traversed and under the situation of the doff unit 10 of coiling package 30 adopting as above-mentioned embodiment; Owing to be rotated driving through 76 pairs of the drive motor that the traverse arm 74 that traverses, so, the width of the package 30 of being reeled can freely be changed.Therefore, the doff unit 10 of this embodiment yarn 20 is traversed to approach reel spool 22 the end the position and form package 30.And the doff unit 10 of this embodiment can traverse yarn 20 near the narrow width in the zone central portion on the direction of principal axis of coiling spool 22 and form package 30.In patent documentation 3 disclosed Yarn winding apparatus for example; Under the situation of the coiling narrow width of package; If keep out of the way the position that when catching the yarn ends of package side through yarn guide portion material, this yarn guide portion material of the arm that traverses (yarn guiding part) Xiang Buyu is interfered; Then compare with the coiling width being positioned at the situation of reeling near the package of the end position of coiling spool, the distance that yarn guiding part is kept out of the way is elongated.The operating efficiency of the doff unit when consequently, carrying out yarn guiding action by yarn guide portion material is low.About this point, in this embodiment,, also can efficient carry out catching the capturing motion etc. of the yarn ends that parts 26 carry out well through last yarn even under the situation of the coiling narrow width of package.
The automatic bobbin winder 1 of this embodiment has the winding unit main body 16 of a plurality of configurations arranged side by side.Automatic bobbin winder 1 respectively has on a device of splicer 14 and one yarn and catches parts 26 in each winding unit main body 16.Thus, thereby connect yarn chassis etc. and when needs connect yarn, make and connect yarn chassis etc. and move to this winder unit and compare with having, can reduce the required time of yarn that connects with the structure that connects yarn.Therefore can enhance productivity.
In the automatic bobbin winder 1 of this embodiment, traverse arm 74 with yarn guiding part 73 compare with base end side be in from be provided with face (vertical surface) away from the mode of position be bearing on the drive motor 76 that traverses (output shaft 77).Thus, because the configuration of the arm 74 that traverses makes yarn guiding part 73 near package 30 and the contact wire that contacts roller 29, so can shorten drift and impression length.
In the automatic bobbin winder 1 of this embodiment, the arm 74 that traverses has the joggling part 72a that bends to the direction near contact roller 29.Can shorten drift and impression length thus.Therefore, owing to can make the action of the yarn 20 that will be wound in the package 30 stable, so can improve the quality of package 30.
In the automatic bobbin winder 1 of this embodiment, yarn guiding part 73 has terminal part 71a and opening portion 71b.Terminal part 71a is at the front restriction yarn 20 of yarn guiding part 73.Opening portion 71b is with the mode that yarn 20 guided to this terminal part 71a base end side opening of swing arm 74 sidelong.Thus, even under the situation that yarn 20 pulls because of vibration and quilt such as force of inertia in traversing, can prevent that also yarn 20 from deviating from from yarn guiding part 73.In addition, owing to easily yarn 20 is guided to yarn guiding part 73, thus can promptly begin to traverse, thus the production efficiency of automatic bobbin winder 1 can be improved.
In the automatic bobbin winder 1 of this embodiment, be formed with rake 73a and the 73b that colludes the opening portion 71b guiding yarn 20 of hanging groove 71 to yarn at yarn guiding part 73.Thus, can be really and carry out as soon as possible therefore the guiding of yarn 20 to yarn guiding part 73, can be improved the production efficiency of automatic bobbin winder 1.
In the automatic bobbin winder 1 of this embodiment, has the package drive motor 41 that directly rotation drives coiling spool 22.Thus, compare, can reduce to contact the diameter of roller 29 with the structure that makes package 30 driven rotations.Therefore, owing to can shorten drift and impression length, so thereby can make that the action of the yarn 20 that will reel is stable can to improve the quality of package 30.
The automatic bobbin winder 1 of this embodiment has the fulcrum of traversing 27.The fulcrum of traversing 27 is the fulcrums that traverse that will be wound on the yarn 20 in the package 30.When the direction of principal axis of contact roller 29 is observed; At least in the end of package 30; With respect to the yarn diatom L3 that the some P1 at the position of the upstream side that will represent the yarn 20 of contact on the roller 29 and the fulcrum 27 of traversing couple together, expression is approximate right angle along the imaginary line L2 of the line of the length direction of the arm 74 that traverses.
Thus, even in the end of the stroke that traverses of the arm 74 that traverses, also can alleviate the yarn 20 that will be wound up in the package 30 because of yarn guiding part 73 situation of warpage significantly.Consequently, in having the automatic bobbin winder 1 that connects yarn feeding device 14, can Yi Bian can connect the yarn operation aptly, not be wound in the package 30 because of 73 pairs of yarns 20 of yarn guiding part apply burden Yi Bian will damage few yarn 20.

Below, first variation of above-mentioned embodiment is described with reference to Fig. 5.In addition, in the explanation of following variation, exist identical with aforesaid embodiment or similar parts are marked identical Reference numeral in the drawings and omit the situation of explanation.
In the above-described embodiment, be traverse the rotation axis L1 and the parallel layout of yarn diatom L3 of arm 74.In first variation, be following such layout: when with yarn diatom L3a to from package 30 away from the direction overtime, rotation axis L1a and yarn diatom L3a are angle θ and intersect.In this variation, the line of drawing to yarn guiding part 73 from the base end part of the arm 74 that traverses, be that imaginary line L2a is not at right angles but is approximate right angle with respect to yarn diatom L3a.Here, so-called " approximate right angle " is meant not only to comprise extremely near the angle at right angle, also comprises the angle of the scope of the ratio broad that imaginary line L2a and the yarn diatom L3a angulation of Fig. 5 is such.
In the automatic bobbin winder 1 of first variation; When side-looking (when the direction of principal axis of contact roller 29 is observed); It is the downstream in yarn road that the intersection point P2 of imaginary line L2a and yarn diatom L3a (in other words, the position of yarn guiding part 73) compares with the intersection point P3 of yarn diatom L3a with the vertical line L4a that guides yarn diatom L3a from the base end part of the arm 74 that traverses into.
Thus, be suitable length, can make package 30 and the contact wire that contact roller 29 near yarn guiding part 73, so can shorten drift and impress length through making the arm 74 of traversing.Therefore, owing to can make the action of the yarn 20 that will reel to package 30 stable, so can improve the quality of package 30.
In addition, in first variation, angle θ is an acute angle, and this angle θ more little (rotation axis L1a approaches parallel with the relation of yarn diatom L3a more), the warpage in the yarn road at place, the end that can reduce to traverse more.
Below, with reference to Fig. 6 second variation is described.In the above-mentioned embodiment and first variation; Traverse the imaginary line L2 of arm 74 with respect to the face tilt that is provided with of doff unit 10; But in second variation, so that the imaginary line L2b of the arm 74 that the traverses mode parallel with respect to the face that is provided with of doff unit 10 disposes the arm 74 that traverses.In addition, also can dispose the arm 74 that traverses with respect to the mode of the face that the is provided with almost parallel of doff unit 10 with the imaginary line L2b of the arm 74 that traverses.
Thus, in the above-mentioned embodiment and first variation, yarn 20 is because guide plate 28 and warpage, but in second variation, realized making yarn 20 layout of warpage hardly from yarn feeder 11 to the arm 74 that traverses.
In addition, the yarn guiding part 73 in second variation is compared with the yarn guiding part 73 of above-mentioned embodiment, remotely disposes with the contact wire that contacts roller 29 from package 30.Therefore, from shortening the viewpoint of drift and impression length, the layout of above-mentioned embodiment is relatively good.
