As shown in Figure 1 and Figure 2, adapter trolley 3 possesses splicer (piecing devices) 43, suction pipe (first catches guide member) 44 and suction nozzle (second catches guide member) 46.When producing broken yarn at a certain spinning unit 2 or yarn cuts off, adapter trolley 3 marches to this spinning unit 2 and stops on above-mentioned track 41.As shown in Figure 2, suction pipe 44 rotates upward centered by axle, sucks and catches the loose thread sent from spinning apparatus 9.Then, suction pipe 44 rotates downward centered by axle, is guided by caught loose thread towards splicer 43.Suction nozzle 46 rotates downward centered by axle, attracts and catch loose thread from package 80.Then, suction nozzle 46 rotates upward centered by axle, is guided by caught loose thread towards splicer 43.Splicer 43 guides the loose thread joint each other come.
Batch up gear 7 possesses reel cage (support) 71, coil holder (maintaining part) 72, coiler drum 73 and traverse gear 74.
Reel cage 71 is made up of a pair more elongated in the vertical arm member.Reel cage 71 can support bobbin 60 and package 80.
Above-mentioned reel cage 71 is provided with a pair (two) coil holder 72.Coil holder 72 keeps the end of bobbin 60 respectively, bobbin 60 can be supported as rotating.
Coiler drum 73 is the parts of the cylinder shape being fixed on the axle drive shaft 79 that spinning frame 1 possesses.The propulsive effort of suitable drive source (such as, electro-motor) is passed to axle drive shaft 79.Coiler drum 73 is driven under the state contacted with the outer peripheral face of the bobbin 60 supported by reel cage 71 (coil holder 72) or package 80, thus can this bobbin 60 of friction-driven or package 80.
Traverse gear 74 possesses the traverse guide 74a that can guide spun yarn 10.Batch up gear 7, making traverse guide 74a reciprocating driving simultaneously coiler drum 73 by omitting graphic driver train, making the package 80 contacted with coiler drum 73 rotate thus, spun yarn 10 is batched while traversing.
The base portion of reel cage 71 is set to rotate around fulcrum 71a.Reel cage 71 is linked with and omits graphic actuator.By driving this actuator, state and bobbin 60 that bobbin 60 or package 80 contact with coiler drum 73 or the state that package 80 is left from coiler drum 73 can be switched.Batch up gear 7 possesses not shown stop mechanism, can brake the rotation of the package 80 of the state left from coiler drum 73.
Then, be described with reference to the detailed formation of Fig. 3 to the coiler drum 73 that above-mentioned batch up gear 7 possesses.
The coiler drum 73 of present embodiment is the columnar component with the outer peripheral face that can contact with bobbin 60 or package 80.Coiler drum 73 is formed as, and its total length (axial length) 73L is longer than the winding width 80W of package 80.Specifically, the spinning frame 1 of present embodiment is for so-called 6 inches of volumes.The stroke (following, to be sometimes called traverse stroke) of the traverse guide 74a that traverse gear 74 possesses is set to, and forms the package 80 that winding width 80W is 152mm.The total length 73L of coiler drum 73 is longer than this winding width 80W (152mm).
Coiler drum 73 possesses cylinder body 75 and high friction part 76.
Cylinder body 75 is the most columnar components forming coiler drum 73.The total length 73L of coiler drum 73 is consistent with the total length of cylinder body 75.Cylinder body 75 is fixed on above-mentioned axle drive shaft 79.Thus, such as, by electro-motor etc., axle drive shaft 79 is driven, rotary actuation can be carried out to cylinder body 75 thus.
High friction part 76 is by can the endless member that forms of the rubber of elastic deformation.In the present embodiment, multiple (two) high friction part 76 is configured with in the periphery of cylinder body 75.The outer peripheral face of this high friction part 76 and friction face 77, form a part for the outer peripheral face of coiler drum 73.
The friction face 77 that each high friction part 76 has is configured to, outstanding a little diametrically compared with the outer peripheral face of cylinder body 75.Thus, when making coiler drum 73 contact with bobbin 60 or package 80, the friction face 77 that high friction part 76 has contacts (in addition than the outer peripheral face of cylinder body 75 of the part not configuring this high friction part 76 more strongly, according to the hardness etc. of package 80, the friction face 77 that also only high friction part 76 has sometimes contacts with bobbin 60, package 80).By this formation, this high friction part 76 of coiler drum 73 stably can contact further with package 80.
The friction face 77 that high friction part 76 has is configured to, and avoids contacting with the both ends in the winding width direction of package 80.As shown in Figure 3, high friction part 76 is respectively configured with one in the left and right of coiler drum 73.The left part of friction face 77 that the high friction part 76 in left side has, is positioned at left part than package 80 more by the position of winding width direction central authorities.The right part of friction face 77 that the high friction part 76 on right side has, is positioned at right part than package 80 more by the position of winding width direction central authorities.
Thus, become 152mm (namely being set to winding width 80W, distance between the left part of package 80 and right part is 152mm) spinning frame 1 when, the left part of the high friction part 76 from left side of the coiler drum 73 of Fig. 3 axial distance 76L to the right part of the high friction part 76 on right side is less than 152mm.In other words, the axial distance 76L in the friction face 77 that two high friction parts 76 have, between the point closest to the left-hand end of coiler drum 73 and the point of the right-hand end closest to coiler drum 73 is less than 152mm.
" winding width " of package 80 refers to and in batch up gear 7, makes spun yarn 10 traversing and the winding width in the moment of batching.Namely, the reason of the larger grade of the coiling tension due to spun yarn 10, after doffing to package 80 becoming full volume, the centre portion of the layer of package sometimes 80 expands ground distortion, but " winding width " in this specification sheets means and do not consider this winding width of being afterwards out of shape.
Then, the formation for high friction part 76 is installed on cylinder body 75 is described.High friction part 76 is fixed by being embedded in the groove portion 78 of the ring-type of the periphery formation of cylinder body 75.
As shown in the section of Fig. 3, groove portion 78 is formed with the width identical with high friction part 76.This groove portion 78 is to arrange with the quantity of above-mentioned high friction part 76 and the mode that arranges position corresponding.
High friction part 76 is formed as having certain thickness cylindrical shape.The internal diameter of this high friction part 76 is formed be less than the external diameter becoming the part of path in cylinder body 75 owing to forming groove portion 78.When at the high friction part 76 making to be made up of rubber towards when installing to groove portion 78 while radial outside elastic deformation, by the restoring force towards radially inner side, and high friction part 76 is strongly fixed on the groove portion 78 of cylinder body 75.As a result, even if do not use the fixing means such as lining cement especially, high friction part 76 also can be made not slide with cylinder body 75 and rotate integratedly.
The thickness of high friction part 76 is formed slightly larger than the degree of depth in the groove portion 78 of coiler drum 73.Thereby, it is possible to the friction face 77 making the high friction part 76 of the state in the groove portion 78 being installed on cylinder body 75 have is outstanding a little from the outer peripheral face of cylinder body 75.
In the present embodiment, high friction part 76 is made up of rubber.The friction face 77 had high friction part 76 is implemented annular knurl processing and is formed tiny concavo-convex, improves friction coefficient thus.According to the above, the friction force produced between high friction part 76 and package 80 can be guaranteed significantly, package 80 can be driven.Thus, when being driven package 80 by high friction part 76, even if the heavier package 80 of the state close to full volume, it also can be made promptly to shift as High Rotation Speed state from halted state.
In batch up gear 7, when can shorten package 80 is rotated from halted state and arrive regulation rotative speed till time time, the capacity rating of package 80 can be improved, advantageously.Especially, the spinning frame 1 of present embodiment is configured to, when yarn defect being detected by yarn qualities analyzer 52, interruption is batched, and restart to batch after carrying out sub operation at this yarn defect of removing, therefore there is batching by the possibility repeating continually to stop and restarting of batch up gear 7.Thus, in batch up gear 7, it is more important for transferring to rapidly common rotative speed for boosting productivity from rotation halted state.
Shortening package 80 transfers to the time required for High Rotation Speed state from halted state, and it is also preferred for improving in this meaning of quality reducing the ribbon wound of package 80.Ribbon wound means that spun yarn 10 is not wound in same area by traversing.Namely, when starting to batch spun yarn 10 to the bobbin 60 of sky or make discontinuedly to batch when restarting, start the rotation of bobbin 60 or package 80 under the state of initial non-hooking spun yarn 10 on traverse guide 74a, make spun yarn 10 not traversing and (positions such as near the central authorities of the winding width of package 80) batch.The rotative speed of bobbin 60 or package 80 become enough large after, start the traversing of spun yarn 10.The reason starting to postpone of the traversing of spun yarn 10 is so made to be: under the state that the rotative speed of bobbin 60 or package 80 is insufficient, the tension force instability of spun yarn 10, therefore cannot make spun yarn 10 be sticked in traverse guide 74a sometimes or spun yarn 10 is wound in traverse guide 74a and becomes and cannot batch.Thus, during the rotative speed of bobbin 60 or package 80 does not arrive usual rotative speed, ribbon wound can be formed, and this ribbon wound becomes the reason that the quality of package 80 is reduced.The coiler drum 73 of present embodiment possesses high friction part 76, therefore, it is possible to make bobbin 60 or package 80 shift as usual slew mode from rotation halted state rapidly.As a result, the special quality package 80 that ribbon wound is less can be produced.
Then, be described with reference to the layout of Fig. 4 to the high friction part 76 of the relation between the traverse stroke according to traverse guide 74a.
Traverse guide 74a is driven reciprocally according to the traverse stroke 74W of the regulation shown in Fig. 4.Batch up gear 7 makes spun yarn 10 while traversing, batch the outer peripheral face of the package 80 in rotating.As shown in Figure 4, in the batch up gear 7 of present embodiment, the traverse stroke 74W of traverse guide 74a is configured to, comprise the width of outermost end to the outermost end of another side being configured with the axial end side of high friction part 76 (friction face 77) from coiler drum 73, and wider than this width.If be described according to the direction of Fig. 4, the position that the left part of high friction part 76 that then left end of the traverse stroke 74W of traverse guide 74a is positioned on the left of than coiler drum 73 more keeps left, the right-hand end of traverse stroke 74W is positioned at the position of more keeping right than the right part of the high friction part 76 on right side.
The traverse stroke 74W of traverse guide 74a is set to, and comprises the width (length suitable with the axial distance 76L in Fig. 3) of the entirety of the friction face 77 that multiple high friction part 76 has, and larger than the width of this entirety.Thereby, it is possible to make spun yarn 10 while with the mode traversing exceeding the contact site between the high friction part 76 of coiler drum 73 and package 80, batch in package 80.
Make spun yarn 10 traversing by traverse guide 74a, spun yarn 10 is turned back at the both ends of the winding width of package 80 and is reeled in meander-shaped thus.As described in Patent Document 3, when friction-driven portion is configured to contact with the both ends of package, yarn is turned back between friction-driven portion and package while bearing powerful friction or constraint.Thus, when having acted on certain fitfull power to the yarn near switch-back point, in the formation of patent documentation 3, yarn is difficult to discharge this power, therefore can think to become easily to produce broken yarn.
Be configured in the batch up gear 7 of present embodiment, the traversing width of traverse guide 74a is wider than the width in the region of the high friction part of the configuration of coiler drum 73 76.In the mode that the high friction part 76 of coiler drum 73 does not contact with the both ends of package 80, according to traverse guide 74a traverse stroke 74W between relation configure this high friction part 76.Thereby, it is possible to avoid the spun yarn 10 near switch-back point to contact with the high friction part 76 of coiler drum 73, even if therefore apply fitfull power to spun yarn 10, spun yarn 10 also can be out of shape etc. as required, thus easy release force.As a result, the broken yarn of the spun yarn 10 near traverse stroke 74W end can effectively be avoided.
The tendency of the hardness axially of package 80 is described.In the ordinary course of things, compared with when being in traverse stroke 74W central with traverse guide 74a, when being in end, yarn path is elongated, and therefore the tension force of spun yarn 10 uprises.Turn back at the both ends spun yarn 10 of package 80, therefore the density of spun yarn 10 is higher.According to the above, the both ends of the axis of package 80 are harder than central portion.Thus, if as described in Patent Document 3, become the layout making friction-driven portion contact with the both ends of hardening package, then can think and package can be made strongly to rotate.
In the present embodiment, high friction part 76 is configured to, and does not contact with the both ends of package 80 and contacts with leaning on ectocentral position a little.The spinning frame 1 of present embodiment possesses Yarn relaxation eliminating device 12, and therefore this Yarn relaxation eliminating device 12 can relax the tension change of the central authorities of above-mentioned traverse stroke 74W and the spun yarn 10 of end well.As a result, the difference of hardness produced between the central authorities and both ends of the winding width of package 80 can be reduced.Therefore, though as in the present embodiment, high friction part 76 is not contacted with the both ends of package 80 and with contact near center side row cutting of going forward side by side a little, also can obtain good propulsive effort.
Then, while the formation of the first variation shown in Fig. 5 and Fig. 4 is compared, the relation between the configuration of high friction part 76 and ribbon wound is described.In Figure 5, from the view point of being convenient to illustrate, the diagram of traverse guide 74a is eliminated.In the explanation of variation afterwards, sometimes give identical meeting and omit the description in the accompanying drawings for the parts identical or similar with above-mentioned embodiment.
Two high friction parts 76 are provided with in the embodiment shown in Fig. 4, but also as shown in the coiler drum 73x of first variation of Fig. 5, further high friction part 76 can be set in the substantial middle position of the winding width (traverse stroke 74W) of package 80.The high friction part 76 of this middle position is configured at the position of axial length two decile of coiler drum 73.In the coiler drum 73x of this formation, also can avoid the broken yarn of the spun yarn 10 near traverse stroke 74W end.
In the coiler drum 73 of Fig. 4, high friction part 76 is avoided the winding width central authorities neighbouring (position of ribbon wound) of package 80 and arranges.Thereby, it is possible to stably carry out ribbon wound, therefore, it is possible to improve the quality of package 80.
As described above, the coiler drum 73 of the batch up gear 7 that the spinning frame 1 of present embodiment possesses, by contacting with package 80 and rotating friction-driven package 80.Coiler drum 73 possesses multiple high friction part 76.Each high friction part 76 has the friction face 77 of a part for the outer peripheral face forming this coiler drum 73.This friction face 77, to have the mode of the friction force higher than other parts (outer peripheral face of cylinder body 75), makes its surface configuration and material and cylinder body 75 differently form.High friction part 76 is all configured to, and friction face 77 contacts with position more in the inner part, the end than package 80.
Thus, even if heavier package 80, also strongly can be driven by high friction part 76, and make it promptly shift as High Rotation Speed state from halted state.In addition, the friction face 77 that high friction part 76 has is set to, and contacts with position more in the inner part, the end than package 80, therefore near the both ends to package 80 either party winding spun yarn 10 time, even if apply fitfull power to this spun yarn 10, also can easily discharge this power.As a result, can effectively avoid producing broken yarn at the both ends of package 80.
In the coiler drum 73 of present embodiment, axial distance 76L in the friction face 77 that multiple high friction part 76 has, between the point closest to a side of coiler drum 73 and the point of another side closest to coiler drum 73, is less than winding width 80W and the 152mm of package 80.
Thus, when package 80 of formation 6 inches volume, carry out strongly friction-driven package 80 by high friction part 76, and either party near the both ends to package 80 reels during spun yarn 10, even if apply fitfull power to this spun yarn 10, also can easily discharge this power.As a result, can effectively avoid producing broken yarn at the both ends of package 80.
The axial length of the coiler drum 73 of present embodiment is more than 152mm.
Thus, when either party winding spun yarn 10 at the both ends of the package 80 to 6 inches of volumes, spun yarn 10 is arranged in the face beyond the outer peripheral face of coiler drum 73, friction face 77.Thus, can avoid producing broken yarn at the both ends of package 80, and the dimensionally stable of package 80 can be made.
In the coiler drum 73 of present embodiment, the friction face 77 that high friction part 76 has is avoided the position of axial length two decile of this coiler drum 73 and configures.
Thereby, it is possible to the ribbon wound part contact that situation near the friction face 77 avoiding high friction part 76 to have and the axial central authorities being formed in package 80 is more, and make the outer peripheral face of package 80 disorderly.(ribbon wound part generally with near the axially central authorities of coiler drum 73 contacts.)
In the coiler drum 73 of present embodiment, high friction part 76 is formed by rubber.
Thereby, it is possible to make package 80 strongly rotary actuation by the formation of low cost.
In the coiler drum 73 of present embodiment, the friction face 77 that high friction part 76 has is formed concavo-convex.
Thereby, it is possible to improve the friction coefficient of friction face 77, therefore, it is possible to strongly friction-driven package 80.
The batch up gear 7 that the spinning frame 1 of present embodiment possesses possesses coiler drum 73 and traverse guide 74a.Traverse guide 74a comprises the overall width of the friction face 77 that (multiple) high friction part 76 has, and makes spun yarn 10 traversing with the stroke larger than this overall width.
Thus, when being guided near traversing end by spun yarn 10 by traverse guide 74a, even if apply fitfull power to this spun yarn 10, also can easily discharge this power.As a result, can effectively avoid producing broken yarn at the both ends of package 80.
The batch up gear 7 of present embodiment possesses two coil holders 72 and reel cage 71.The end of the bobbin 60 of parallel package remains and can rotate by coil holder 72.Reel cage 71 carrying cylinder pipe bracket 72.In addition, parallel package refers to the package formed at the upper winding yarn of the bobbin (core pipe) of cylindrical shape.
Thereby, it is possible to avoid producing broken yarn at the both ends of parallel package 80, special quality package 80 can be produced.
The spinning frame 1 of present embodiment possesses batch up gear 7 and Yarn relaxation eliminating device 12.Yarn relaxation eliminating device 12 is arranged at than batch up gear 7 more by the position of yarn direct of travel upstream side.Yarn relaxation eliminating device 12 absorbs the tension change of the spun yarn 10 between this Yarn relaxation eliminating device 12 and batch up gear 7.
Thereby, it is possible to relaxed the tension change accompanied with the traversing of spun yarn 10 by Yarn relaxation eliminating device 12.As a result, in formed package 80, difference of hardness can be reduced at the both ends of axis and central portion.Thus, even if the position that high friction part 76 is contacted than package 80 both ends more in the inner part, also can strongly friction-driven package 80.
In the spinning frame 1 of present embodiment, the high friction part 76 of coiler drum 73 is avoided starting to rotate at this coiler drum 73 position that tightly, spun yarn 10 is not reeled by above-mentioned traverse guide 74a traversing and is configured.
Thereby, it is possible to avoid high friction part 76 and ribbon wound part contact and make layer disorderly, therefore, it is possible to realize the high quality of package 80.
The spinning frame 1 of present embodiment possesses spinning apparatus 9, splicer 43, suction pipe 44 and suction nozzle 46.Suction pipe 44 catches the spun yarn 10 from spinning apparatus 9 and guides to splicer 43.Suction nozzle 46 catches the spun yarn 10 from package 80 and guides to splicer 43.
Thus, in spinning frame 1, such as, when spun yarn 10 is cut off or produces broken yarn due to detection yarn defect, spun yarn 10 can be caught to carry out joint.In spinning frame 1, in order to carry out an operation by splicer 43, in batch up gear 7, needing the rotation making package 80 to stop, needing the rotation of package 80 is restarted after sub operation.According to above-mentioned formation, package 80 can be made to shift at short notice as High Rotation Speed state by high friction part 76, therefore, it is possible to improve the production efficiency of package 80.
Then, with reference to Fig. 6, the second variation is described.In the coiler drum 73y of the second variation, for the end side of package 80, be only provided with a high friction part 76x.This high friction part 76x is arranged between an end of package 80 and the central portion of winding width.High friction part 76x in order to strongly drive package 80, and is formed as the width wider than the high friction part 76 of the coiler drum 73 shown in Fig. 4.Thereby, it is possible to provide a kind of coiler drum 73y that just can be avoided the broken yarn produced at the both ends of package 80 by less number of components.From the parallelism stably maintained between the S. A. of coiler drum 73 and the S. A. of package 80, the viewpoint that package 80 is rotated swimmingly is set out, and preferably configures two high friction parts 76 symmetrically as shown in Figure 4.
As shown above, the coiler drum 73y of this variation is by contacting with parallel package 80 and rotating friction-driven package 80.Coiler drum 73y possesses high friction part 76x.High friction part 76x has the friction face 77 of a part for the outer peripheral face forming coiler drum 73y.There is with friction face 77 mode of the friction force higher than other parts, make the surface configuration of friction face 77 and other parts of material and this different.High friction part 76x is configured to, and friction face 77 contacts with position more in the inner part, the end than package 80.
Thereby, it is possible to the high friction part 76x arranged by the both ends avoiding package 80 promptly drives parallel package 80, and can avoid producing broken yarn at the both ends of package 80.
Then, with reference to Fig. 7, the 3rd variation is described.The coiler drum 73z of the 3rd variation is made up of the multiple parts split in the axial direction.Specifically, coiler drum 73z possesses two high friction part 76y, the first barrel 81 and two second tin roller bodies 82.
High friction part 76y is formed as shorter cylindric by materials such as resins, and its outer peripheral face and friction face 77 are carried out annular knurl processing.The axial both ends of high friction part 76y are formed as zig-zag.
First barrel 81 is formed as cylindric by materials such as resins, configures in the mode be clipped between high friction part 76y.The axial both ends of the first barrel 81 are formed as zig-zag in the mode corresponding with the toothed section of high friction part 76y.
Second tin roller body 82 is formed as cylindric by the material identical with the first barrel 81, and is configured in the position suitable with the end of coiler drum 73z.The end of the axially inner side in second tin roller body 82 is formed as zig-zag in the mode corresponding with the toothed section of high friction part 76y.
In this formation, by configuring second tin roller body 82, high friction part 76y, the first barrel 81, high friction part 76y, second tin roller body 82 successively from axial end side, and each parts zig-zag end is each other fitted together to, each parts are linked to relatively to rotate thus.By more than, form coiler drum 73z.
The coiler drum 73z of this variation is, the boundary portion between high friction part 76y and the part beyond it becomes meander-shaped, therefore spun yarn 10 be difficult to enter be formed in the groove of this boundary portion in be favourable.By preparing multiple first barrel 81 with different length in advance, and changing as required, easily can tackle the change of the winding width of package 80 thus.
Above the preferred embodiment of the present invention and variation are illustrated, but above-mentioned configuration example is if change as described below.
The material of high friction part 76,76x, 76y is not limited to rubber and resin, such as, can use the other materials such as metal.In addition, the material of high friction part 76, the material of 76x, 76y and other parts (such as, cylinder body 75, first barrel 81 or second tin roller body 82) of coiler drum also can be made identical.In this case, such as, by concavo-convex processing such as annular knurl processing, the friction coefficient of friction face 77 is increased, make the friction force of friction face 77 increase than other parts thus.
Also annular knurl processing can not be implemented especially for friction face 77.Also to the both sides of friction face 77 and other parts (such as, each outer peripheral face of cylinder body 75, first barrel 81 or second tin roller body 82), identical annular knurl processing can be implemented.In these cases, such as, by making, cylinder body 75 is resin-made, high friction part 76 is rubber system, and the friction force of high friction part 76 can be made thus to increase than other parts.
The method of fixing high friction part 76,76x, 76y is not limited to use groove portion 78 or use toothed section, such as, also can use lining cement and/or screw threads for fastening etc.
The present invention is not limited to so-called 6 inches of volume use, such as, also can be applied to the coiler drums that 3 inches of volumes are used, 4 inches are rolled up, can also be applied to the coiler drum of the package of the winding width for the formation of the size more than 6 inches of volumes.In other words, the present invention also can be applied to coiler drum for the formation of the package of batching according to the traversing width beyond 152mm and batch up gear.Even if in this case, as long as the mode that contacts with position more in the inner part, the end than package of the friction face also had with high friction part or configure high friction part than the stroke mode more in the inner part of traverse guide with the overall width of friction face.
The traverse gear 74 illustrated in the above-described embodiment, in order to avoid with the collisions such as peripheral parts, and not only relative to coiler drum 73 outer peripheral face and also form the position in gap to a certain degree relative to the outer peripheral face of package 80, make traverse guide 74a crank motion.Thus, the distance between the position that the outer peripheral face of the position that spun yarn 10 and traverse guide 74a cannot be made to engage and spun yarn 10 and coiler drum 73 or package 80 contacts becomes zero.Below, above-mentioned distance is called drift.When drift is longer, the distortion of spun yarn 10 absorbs the leeway change of the traversing of traverse guide 74a greatly.Therefore, even if traverse stroke is identical, the winding width of the package 80 formed when drift is longer, than little compared with the winding width of the package 80 formed short in drift.So, owing to there is the impact of drift, even if so traverse stroke is set as more than 152mm, the winding width of package 80 sometimes also can become and be narrower than 152mm.In this case, as long as to make friction face 77 configure high friction part 76 (76x, 76y) in the mode contacted with package 80 more in the inner part than the winding width being narrower than 152mm.
From to bobbin 60 batch spun yarn 10 from the beginning of, to package 80 becomes the state close to full volume, the winding width of package 80 is not limited to constant.Such as, starting under the initial state of batching spun yarn 10 to bobbin 60, due to the thinner thickness of layer, therefore package 80 is comparatively hard, but when batch carry out and layer is thickening time, package 80 deliquescing sometimes.So the point that coiler drum 73 and package 80 contact substantially, moves towards upstream side or downstream gradually along with the carrying out of batching, along with this moves and the change of above-mentioned drift, winding width is impacted.So, the winding width of package 80, from batch play full volume till during, can change according to situation.High friction part 76 (76x, 76y) is preferably configured, and friction face 77 contacts with the width position more in the inner part than the package 80 when winding width becomes the narrowest in package 80.
In the above-described embodiment, spun yarn 10 is pulled out by Yarn relaxation eliminating device 12 from spinning apparatus 9.But, be not limited thereto, also can be configured to, pull out spun yarn 10 by the outlet roller and niproll being arranged at the downstream of spinning apparatus 9 from spinning apparatus 9, and stockpile pulled out spun yarn 10 by the Yarn relaxation eliminating device 12 in downstream.
Coiler drum of the present invention and batch up gear are not limited to the spinning machines such as spinning frame, such as, can be widely used in possessing the Yarn winding machines such as the automatic bobbin winder that can arrange the Yarn supply device for yarn bobbin being wound with yarn.
