Next, the first control units 10 to winder unit 2 is illustrated.First control units 10 has as calculation process The CPU (Central Processing Unit: central processing unit) of device, it stores control program performed by CPU and is controlling The ROM (Read Only Memory: read-only memory) of data used in processing procedure sequence and for program execute when it is interim Above-mentioned RAM (Random Access Memory: random access memory) of storing data etc., to from remaining yarn sensor 23, yarn The signal of sensor 55a~55c, yarn clearer 96 etc. is received or to unwinding yarn auxiliary device 22, winding drum motor 35, the movement of cutter etc. of accumulation drum motor 43, solenoid valve 81, yarn splicing device 94, yarn clearer 96 is controlled.

Next, being illustrated to the movement of winder unit 2.

(initial extension yarn)

Before automatic bobbin winder 1 (winder unit 2) forms package P, extension yarn is carried out to winder unit 2.Opposite direction winding is single The sequences that member 2 hang yarn are illustrated, firstly, operator is from for yarn bobbin Bk unwinding yarns Y, and successively by the yarns Y Unwinding yarn auxiliary device 22, yarn under working blowing device 91, tensioner 92 and thread guides 51 are set to, and are fixed on volume Around bobbin Bm.At this point, as shown in fig. 6, the yarns Y drawn upwards from tensioner 92 is directly hung to thread guides 51, and It is not through the internal flow path 52a of the yarn flow path 53a and yarn guide member 52 that blow down nozzle 53.In addition, fixed The extension yarn to mound bobbins Bm is carried out by Automatic doffing devices 3 in the yarns Y of mound bobbins Bm.

Next, as shown in fig. 7, operator will be crossed on yarn feeder 11 and package shape and being arranged as described above At the part close to wire loop 73 of the yarns Y between portion 12, wire loop 73 is imported from opening portion 73a.It is carried out as a result, to steel wire The extension yarn of circle 73.At this point, in the case where wire loop 73 is located at the position for leaving yarns Y of orbit portion 72c, by making wire loop 73 move along orbit portion 72c close to after yarns Y, and yarns Y is imported wire loop 73.So, in present embodiment In, yarn feeder 11 and the yarns Y being wrapped between forming portion 12 will be crossed on from the opening portion 73a of wire loop 73 and import wire loop 73, thus, it is possible to carry out the extension yarn to wire loop 73, therefore it can easily be done the extension yarn to wire loop 73.

Then, after carrying out the extension yarn to wire loop 73, the power supply etc. of winder unit 2 is connected, starts winder unit 2 Movement.Then, as shown in figure 8, winder unit 2 passes through the control of first control units 10, it is first begin to rotation accumulation roller 50 It rotates (S101).As a result, from for yarn bobbin Bk unwinding yarns Y.Then, as shown in figure 9, wire loop 73 and rotation accumulation roller 50 Rotation linkage and rotate, by the yarns Y of unwinding be wound in rotation accumulation roller 50 outer peripheral surface, thus carry out to rotate accumulation The extension yarn of roller 50.

Here, if it is different from present embodiment, without contact plate 74, hinder wire loop 73 relative to rotation accumulation roller 50 Movement resistance it is too small, even if then rotation accumulation roller 50 rotates, wire loop 73 also do not rotate, thus in the presence of can not will be from confession (there is no normal direction rotation accumulation roller in the worry that the yarns Y of yarn bobbin Bk unwinding is wound in the outer peripheral surface of rotation accumulation roller 50 50 hang the worry of yarn).On the other hand, in the present embodiment, it is provided with contact plate 74, so as to wire loop 73 Apply the resistance for hindering the movement relative to rotation accumulation roller 50.Therefore, as described above, wire loop 73 and rotation accumulation roller 50 rotation links and rotates, so as to carry out extension yarn to rotation accumulation roller 50.

Then, until completing to the extension yarn for rotating accumulation roller 50 (S102: no), the state is maintained, is completed to rotation Turn to make the rotation of winding drum 31 start (S103) when the extension yarn of accumulation roller 50 (S102: yes).As a result, in winder unit 2 In, acted as follows: accumulation movement unwinds the yarns Y for yarn bobbin Bk by the rotation of rotation accumulation roller 50, and By the yarns Y of unwinding be wound in rotation accumulation roller 50 outer peripheral surface and accumulation；And package formation movement, i.e., by with winding The rotation of roller 31 links and the rotation of the mound bobbins Bm of rotation, draws accumulation in the yarns Y of rotation accumulation roller 50, and make The yarns Y of extraction is wound in mound bobbins Bm in traversing.

Here, in the present embodiment, make to rotate the rotation of accumulation roller 50 in this way to unwind the yarn for yarn bobbin Bk Line Y, so as to which the yarns Y of unwinding is wound in rotation accumulation roller 50 and by its accumulation.Therefore, in the present embodiment, In addition to rotating accumulation roller 50, do not need separately to be arranged for from the mechanism etc. for yarn bobbin Bk unwinding yarns Y.

Then, the broken yarn (S105: no) caused by yarn defect (S104: no) is not detected, does not generate because of tension, for tube Pipe Bk is remained during having yarns Y (S106: no), continues the common volume of accumulation movement with package formation movement the two Around.In addition, carrying out aftermentioned yarn defect removing movement (S107) when detecting yarn defect (S104: yes), returning to S104 later.Separately Outside, when detecting broken yarn (S105: yes), aftermentioned broken yarn recovery action (S108) is carried out, returns to S104 later.In addition, For yarn bobbin Bk yarns Y light when (S106: yes), carry out aftermentioned bobbin change movement (S109), return to S104 later.

Here, in the present embodiment, in the case where detecting yarn defect by yarn clearer 96, it is judged to detecting in S104 Yarn defect.In addition, not detecting yarns Y by yarn clearer 96, and detect there is being yarn for yarn bobbin Bk is surplus by remaining yarn sensor 23 In the case where line Y, the broken yarn caused by S105 is judged to generating because of tension.In addition, not detecting yarns Y by yarn clearer 96, And it is not detected to be determined as in S106 for yarn bobbin Bk in the case where remaining for yarn bobbin Bk has yarns Y by remaining yarn sensor 23 Yarn used up.

(yarn defect removing movement)

Next, the yarn defect removing movement to S107 is illustrated.It is first as shown in Figure 10 (a) in yarn defect detection operation First, the cutter cutting continuous strand Y (S201) of yarn clearer 96 is utilized.Then, stop the rotation (accumulation movement) for rotating accumulation roller 50 Only (S202).As a result, in cut-off yarns Y, by the loose thread position of the yarns Y of 13 side of yarn reserving portion (package 12 side of forming portion) Near the outer peripheral surface of rotation accumulation roller 50 or its, the loose thread of the yarns Y of 11 side of yarn feeder is in from yarn under working blowing device 91 states hung down.

Next, the yarns Y of 13 side of yarn reserving portion is drawn (S203) to 11 side of yarn feeder.It is said in more detail It is bright, in S203, firstly, rotating rotation accumulation roller 50 to direction opposite when acting with accumulation, and open solenoid valve 81 Air stream is generated to yarn flow path 53a from flow path 53b is blown down.Then, yarn is leaned on the outer peripheral surface of rotation accumulation roller 50 The loose thread of the yarns Y of 13 side of line reserving portion is attracted by yarn guide member 52, the yarns Y for 13 side of yarn reserving portion being attracted Loose thread as described above via the internal flow path 52a of yarn guide member 52, blow down yarn flow path 53a and the guidance of nozzle 53 The thread path 97a of component 97 and the lower end for being drawn to thread path 97a.

Here, in the present embodiment, in initial extension yarn, do not make yarns Y by blowing down the yarn flow of nozzle 53 The internal flow path 52a of road 53a, yarn guide member 52, but so that yarns Y is passed through above-mentioned access by the movement of S203.

Then, as described above, using upper yarn capture device 93 to the lower end for leading to thread path 97a in S203 The yarns Y of 13 side of yarn reserving portion attracted, above-mentioned yarns Y is thus imported into yarn splicing device 94 (S204).Next, sharp The yarns Y of 11 side of yarn feeder is blown afloat with yarn under working blowing device 91, and attracts to capture using yarn under working capture device 95 and be blown Thus the yarns Y of 11 side of yarn feeder is imported yarn splicing device 94 (S205) by the yarns Y risen.In addition, S205 can S202 it Afterwards, it carries out, can also be carried out simultaneously with S203, S204 before S203, S204.

Next, yarn splicing device 94 is made to execute the yarns Y of 11 side of yarn feeder imported and the yarns Y of 13 side of yarn reserving portion Meet yarn (S206).Then, it after the completion of connecing yarn, starts again at the rotation (accumulation movement) of winding drum 31 (S207), returns S104。

(broken yarn recovery action)

Next, the broken yarn recovery action to S108 is illustrated.It is first as shown in Figure 10 (b) in broken yarn recovery action First, the rotation (accumulation movement) for rotating accumulation roller 50 is made to stop (S301).Then, by the yarns Y and yarn of 11 side of yarn feeder The yarns Y of 13 side of line reserving portion is directed respectively into yarn splicing device 94 (S302).Here, in S302, for example, according to it is above-mentioned The yarns Y of 13 side of the yarns Y of 11 side of yarn feeder and yarn reserving portion is imported yarn splicing device by the identical sequence of S204, S205 94.Also, at this point, according to broken yarn generate position, drawn in a manner of identical with S203 13 side of yarn reserving portion yarns Y it Afterwards, the yarns Y of 13 side of yarn reserving portion of extraction is imported into yarn splicing device.Next, yarn splicing device 94 is made to execute feeding for importing The yarns Y of the yarns Y and 13 side of yarn reserving portion of 11 side of yarn portion meets yarn (S303).Then, after the completion of connecing yarn, make winding drum 31 rotation (accumulation movement) starts again at (S304), returns to S104.

(bobbin change movement)

Next, the bobbin change movement to S109 is illustrated.It is first as shown in Figure 10 (c) in bobbin change movement First, the rotation (accumulation movement) for rotating accumulation roller 50 is made to stop (S401).Then, yarn is discharged from for yarn bobbin supporting part 21 Used up for yarn bobbin Bk, and it is new for yarn bobbin Bk from bobbin supply apparatus to being supplied for yarn bobbin supporting part 21 (S402).Next, the yarns Y of 13 side of the yarns Y of 11 side of yarn feeder and yarn reserving portion is directed respectively into yarn splicing device 94 (S403).Here, in S403, for example, according to sequence identical with above-mentioned S204, S205 by the yarns Y of 11 side of yarn feeder with And the yarns Y of 13 side of yarn reserving portion imports yarn splicing device 94.In addition, in bobbin change movement, yarn reserving portion in S403 Importing of the yarns Y of 13 sides to yarn splicing device 94 can also carry out before S402.Next, yarn splicing device 94 is made to execute importing The yarns Y of yarns Y and yarn reserving portion 13 side of 11 side of yarn feeder meet yarn (S404).Moreover, making to roll up after the completion of connecing yarn Rotation (accumulation movement) around roller 31 starts again at (S405), returns to S104.

(rotation speed of rotation accumulation roller when being commonly wrapped about)

Next, being acted with both package formation movements when being commonly wrapped about using the flow chart of Figure 11 to accumulation is carried out The rotation speed of rotation accumulation roller 50 be illustrated.The process of Figure 11 when being commonly wrapped about beginning, i.e. accumulation movement with Both package formation movements start when starting.When being commonly wrapped about, accumulation is few in the amount of the yarns Y of rotation accumulation roller 50, When not detecting yarns Y by upper limit Yarn senser 55a (S501: no), make to rotate accumulation roller 50 with defined rotation speed Vc1 rotates (S502).Here, rotation speed Vc1 is that yarns Y than makes to wind as described later from the withdrawal speed for yarn bobbin Bk The fast rotation speed of the off speed of yarns Y from rotation accumulation roller 50 when roller 31 is with rotation speed Vm1 rotation.Therefore, During making to rotate accumulation roller 50 with rotation speed Vc1 rotation, accumulation increases in the amount of the yarns Y of rotation accumulation roller 50 Add.

On the other hand, when detecting yarns Y by upper limit Yarn senser 55a (S501: yes), make to rotate accumulation roller 50 rotate (S503) with the rotation speed Vc2 slower than above-mentioned rotation speed Vc1.Here, rotation speed Vc2 is yarns Y from for yarn The withdrawal speed of bobbin Bk than making yarns Y of the winding drum 31 with rotation speed Vm1 rotation when from rotation accumulation as described later The slow rotation speed of the off speed of roller 50.Therefore, during making to rotate accumulation roller 50 with rotation speed Vc2 rotation, Accumulation is reduced in the amount of the yarns Y of rotation accumulation roller 50.

Moreover, be commonly wrapped about continue during (S504: yes), controlled as above-mentioned S501~S503 rotation store Stay the rotation speed of roller 50.Accumulation remains close to pass with upper limit yarn in the amount of the yarns Y of rotation accumulation roller 50 as a result, The amount of the corresponding accumulation amount of sensor 55a.In addition, in the rotation for the accumulation roller 50 that stops rotating as above-mentioned S202, S301, S401 When turning etc., do not go on be commonly wrapped about when, terminate the process of Figure 11.

(rotation speed of winding drum)

Next, the flow chart using Figure 12 is illustrated the rotation speed of winding drum 31.The process of Figure 12 is being rolled up Dress formation movement starts when starting.

When formation movement beginning is wrapped, winding drum 31 is made to rotate (S601) with defined rotation speed Vm1.Moreover, During carrying out accumulation movement (during rotation accumulation roller 50 rotates) (S602: no), by the rotation speed of winding drum 31 Degree maintains Vm1.

On the other hand, when rotating rotation (accumulation movement) stopping of accumulation roller 50 in above-mentioned S201, S301, S401 (S602: yes), in the case where detecting yarns Y by lower limit Yarn senser 55b (S603: yes), by the rotation of winding drum 31 Rotary speed maintains Vm1 (S604).In addition, not detecting yarns Y (S603: no) by lower limit Yarn senser 55b, but by most In the case that lower limit Yarn senser 55c detects yarns Y (S605: yes), the rotation speed of winding drum 31 is made to be decelerated to ratio Vm1 slow Vm2 (S606).In addition, not by most lower limit Yarn senser 55c detects yarns Y in the case where (S605: no), Make the rotation of winding drum 31 that formation movement be wrapped and stops (S607).So, in the present embodiment, acted in accumulation During stopping, accumulation is fewer in the amount of the yarns Y of rotation accumulation roller 50, and (package is formed the rotation speed of winding drum 31 Off speed of the yarns Y of movement from rotation accumulation roller 50) it is slower.

Moreover, during until accumulation movement starts again in S207, S305, S404 (S608: no), such as above-mentioned S603 ~S607 controls the rotation speed of winding drum 31 like that, and accumulation movement when starting again in S207, S305, S404 (S608: yes) returns to S601.

In the present embodiment, due to having in rotation 50 accumulation of accumulation roller from the yarns Y unwound for yarn bobbin Bk, Even if accumulation movement stops in S201, S301, S401 as described above, package formation movement also can continue to.But it is storing During staying movement to stop, yarns Y is not supplied to rotation accumulation roller 50, therefore accumulation is in rotation 50 yarns Y of accumulation roller Amount is reduced due to formation movement is wrapped and continues.

On the other hand, in the present embodiment, in accumulation in the case where rotating more than the amount of yarns Y of accumulation roller 50 (in the case where more than accumulation amount corresponding with lower limit Yarn senser 55b), makes winding drum 31 with identical as when being commonly wrapped about Rotation speed Vm1 rotation, thus, it is possible to efficiently carry out package P formation.On the other hand, in accumulation in rotation accumulation roller The amount of 50 yarns Y reduce and in the case where tailing off (in the case where fewer than accumulation amount corresponding with lower limit Yarn senser 55b), The Vm2 for keeping the rotation speed ratio Vm1 of winding drum 31 slow.Thereby, it is possible to slow down accumulation in the yarns Y of rotation accumulation roller 50 Reduction, so as to extend make be wrapped formation movement continue time.Connect what yarn etc. can use as a result, being able to extend Time.In addition, accumulation in the case where the amount of yarns Y for rotating accumulation roller 50 is further reduced and almost disappears (than with In the case that the most corresponding accumulation amount of lower limit Yarn senser 55c is few), the rotation for stopping winding drum 31 (is wrapped to be formed and move Make).Thereby, it is possible to prevent yarns Y from completely disappearing from rotation accumulation roller 50.

It is illustrated next, implementing variation obtained from various changes to present embodiment.

In the above-described embodiment, in initial extension yarn, make yarns Y not by blowing down the yarn flow path 53a of nozzle 53 And the internal flow path 52a of yarn guide member 52, however, it is not limited to this.In initial extension yarn, yarns Y can also be made logical Cross yarn flow path 53a and internal flow path 52a.

In addition, in the above-described embodiment, as shown in fig. 6, operator will be crossed on yarn feeder 11 and package forming portion Yarns Y between 12 carries out extension yarn to wire loop 73 as shown in Figure 7, then, starts the rotation for rotating accumulation roller 50, but simultaneously It is not limited to this.In a variation (variation 1), as shown in figure 13, rotation accumulation roller 50 be configured at wire loop 73 along The movement routine (a part of yarn limiting unit 63) of orbit portion 72c and identical as Fig. 6 it is crossed on yarn feeder 11 and package shape The position intersected at the yarns Y between portion 12 is (positioned at the yarn road for being crossed on yarn feeder 11 and the yarns Y being wrapped between forming portion 12 On).

At this point, without the extension yarn from operator to wire loop 73, but start the rotation for rotating accumulation roller 50. Then, it is crossed on the portion yarns Y between yarn feeder 11 and package forming portion 12, Chong Die with the movement routine of wire loop 73 Point, from opening portion, 73a is imported into wire loop 73, to automatically carry out the extension yarn to wire loop 73.At this point, 73 conduct of wire loop It hangs yarn portion and functions.Moreover, hereafter, rotation accumulation roller 50 further rotates, thus identically as above embodiment Carry out the extension yarn to rotation accumulation roller 50.

At this point, the freedom degree for rotating the configuration of accumulation roller 50 is lower, but does not need to operate compared with above embodiment Personnel carry out the extension yarn to wire loop 73 manually, therefore can reduce the burden of initial operator when hanging yarn.

In addition, in the above-described embodiment, applying to wire loop 73 and hindering by contacting contact plate 74 with wire loop 73 Hinder the resistance of the movement relative to rotation accumulation roller 50, however, it is not limited to this.

In another variation (variation 2), as shown in figure 14,74 (reference of contact plate is configured in the above-described embodiment Fig. 5 (b)) position rubber magnet iron plate 101 (" resistance applying unit " of the invention) is set, and replace contact plate 74.At this point, steel wire The magnetic force generated between circle 73 and rubber magnet iron plate 101 becomes the movement for hindering wire loop 73 relative to rotation accumulation roller 50 Resistance.In addition, at this point, wire loop 73 is formed to package using the magnetic force generated between wire loop 73 and rubber magnet iron plate 101 12 layback of portion is close.

In addition, as shown in Figure 15 (a), replacing contact plate 74 in another variation (variation 3) (referring to Fig. 5 (b)) Setting, and cricoid magnet 106 (" resistance applying unit " of the invention) is configured in the extension 72a of guide rail 72.Magnet 106 is for example It is neodium magnet etc..Hinder wire loop 73 relative to rotation accumulation at this point, the magnetic force generated between wire loop 73 and magnet 106 becomes The resistance of the movement of roller 50.In addition, at this point, using the magnetic force of wire loop 73 and magnet 106 by wire loop 73 to yarn feeder 11 Layback is close.

In addition, the tapering 62a of flange 62 is in the axial direction of rotation accumulation roller 50 than above-mentioned embodiment party in variation 3 Formula is long, further extends to package 12 side of forming portion than the case where above embodiment.The yarns Y for hanging yarn to wire loop 73 as a result, is temporary When be difficult to fall off from wire loop 73.But the tapering 62a of the flange 62 of variation 3 is not limited to as described above rotating Long structure can also be identical as above embodiment (variation 4) as shown in Figure 15 (b) in the axial direction of accumulation roller 50.

In addition, in another variation (variation 5), as shown in figure 16, in wire loop 73 by rotating accumulation roller 50 The end of radial inside magnet 111 (resistance applying unit) is set.At this point, being set to the magnet 111 and and magnetic of wire loop 73 Iron 111 is opposed and the matrix 71 that is made of metal material between the magnetic force that generates become and hinder wire loop 73 relative to rotation accumulation The resistance of the movement of roller 50.In addition, in the present embodiment, matrix 71 is equivalent to metal portion according to the present invention.

In addition, magnet 111 also can be set it is in wire loop 73, be made of with rotation accumulation roller 50 metal material The opposed part different from variation 5 of arbitrary portion.At this point, the part phase opposed with magnet 111 of rotation accumulation roller 50 When in metal portion of the invention.

In addition, as shown in Figure 17 (a), Figure 17 (b), yarn limiting unit 63 has resistance in another variation (variation 6) Power applies 116 (" resistance applying units " of the invention) of brush, and replaces contact plate 74 and pressing plate 75.Resistance applies brush 116 and exists The upper end of the outer peripheral surface of matrix 71 is extended in a manner of the complete cycle throughout the outer peripheral surface, and is contacted with wire loop 73.At this point, steel Wire ring 73 applies brush 116 with resistance and contacts when moving along guide rail 72, hinders to store relative to rotation to apply wire loop 73 Stay the resistance of the movement of roller 50.

Furthermore, it is also possible to be not provided with above-mentioned contact plate 74, rubber magnet iron plate 101, magnet 106,111, resistance application brush The structure of 116 etc the resistance for applying movement of the obstruction relative to rotation accumulation roller 50 to wire loop 73.For example, The case where wire loop 73 and the resistance to sliding of guide rail 72 are large enough to some extent is inferior, even if not setting separately for applying to wire loop 73 The structure for hindering the resistance of the movement relative to rotation accumulation roller 50 is also capable of increasing and is applied to from rotation 50 court of accumulation roller The tension for the yarns Y drawn to package forming portion 12.In addition, due in initial extension yarn, wire loop 73 and rotation accumulation rolling The rotation of cylinder 50 links and moves, therefore can carry out extension yarn to rotation accumulation roller 50.

In addition, the structure of guide rail and wire loop is not limited to the structure of above embodiment.In (the deformation of another variation Example 7) in, as shown in Figure 18 (a), Figure 18 (b), in above-mentioned variation 6, replaces guide rail 72 and guide rail 121 is set, replace steel wire It encloses 73 and wire loop 122 is set.Guide rail 121 has to be stretched out from the periphery of matrix 71 towards the radial outside of rotation accumulation roller 50 Extension 121a and orbit portion 121b from the front end of extension 121a to upper and lower two sides that separately extend from.In addition, wire loop 122 are installed on orbit portion 121b in such a way that opening portion 122a is towards the radial inside of rotation accumulation roller 50.

Even if in this case, also identical as above embodiment, from rotation accumulation roller 50 to package 12 side of forming portion The yarns Y of extraction is limited by wire loop 122 and is moved.The yarns Y that thereby, it is possible to keep drawing, to prevent from being wound in rotation storage Stay the yarns Y relaxation of roller 50.

Even if, also can be by the yarn that will be crossed on yarn feeder 11 and be wrapped between forming portion 12 in addition, in this case Line Y imports wire loop 122 from opening portion 122a to carry out extension yarn to wire loop 122.At this point, wire loop 122 as hang yarn portion and It functions.Further, it is possible to be carried out by making to rotate the rotation of accumulation roller 50 in the state of hanging yarn in wire loop 122 to rotation Turn the extension yarn of accumulation roller 50.

In addition, in variation 7, it is identical as variation 6, applied by resistance and brushes 116 pairs of application obstruction phases of wire loops 122 For rotating the resistance of the movement of accumulation roller 50, but in variation 7, contact plate 74, rubber magnet iron plate can also be passed through 101, magnet 106,111 to apply wire loop 122 resistance for hindering the movement relative to rotation accumulation roller 50.

In addition, in above embodiment, variation 1~7, wire loop 73,122 is that have that opening portion 73a, 122a's is big The component in C word shape is caused, it can be by the way that yarn feeder 11 and the yarns Y being wrapped between forming portion 12 will be crossed on from opening portion 73a, 122a import to carry out extension yarn to wire loop 73,122, and however, it is not limited to this.Wire loop 73,122 can also by with Above-mentioned different structure come to be crossed on yarn feeder 11 and be wrapped forming portion 12 between yarns Y carry out extension yarn.

In addition, yarn limiting unit is not limited to the structure with wire loop and the guide rail for guiding steel wire circle.Again In one variation (variation 8), as shown in Figure 19, Figure 20 (a), Figure 20 (b), yarn limiting unit 130 has matrix 131 and flier 132 (" bar-like members " of the invention).The substantially cylindrically shaped component of matrix 131, is configured in the upper surface of flange 62 Centre portion.Flier 132 is made of metal material etc., and there are two part 132a, 132b for tool.Part 132a is configured at rotation accumulation roller On 50 axis C, extended parallel to the axial direction of rotation accumulation roller 50, and be rotatably supported in matrix 131.Part 132b from The front end of part 132a extends radially to the position more more outward than flange 62 to rotation accumulation roller 50.

In addition, the end in the radial outside in the face by 12 side of forming portion is wrapped in the axial direction of flange 62 is provided with ring The rubber magnet iron plate 133 of shape, rubber magnet iron plate 133 are opposed with the part 132b of flier 132.As a result, in variation 8, by gold Belonging to the magnetic force generated between the flier 132 and rubber magnet iron plate 133 that material is constituted becomes obstruction flier 132 relative to rotation accumulation The resistance that roller 50 rotates.In addition, in variation 8, from rotation accumulation roller 50 to the yarns Y of package 12 side of forming portion extraction After the front end (" hanging yarn portion " of the invention) for the part 132b for being suspended to flier 132, it is suspended to thread guides 51, and court It is brought out to package forming portion 12.

It is moved at this point, being limited from rotation accumulation roller 50 to the yarns Y that package 12 side of forming portion is drawn by flier 132.By This, is able to maintain the yarns Y of extraction, to prevent the yarns Y relaxation for being wound in rotation accumulation roller 50.

In addition, at this point, the yarns Y with extraction is rotating accumulation roller 50 along the outer peripheral surface of rotation accumulation roller 50 Move up linkage week, flier 132 rotates, and the front end of part 132b is being rotated along the outer peripheral surface of rotation accumulation roller 50 The week of accumulation roller 50 moves up.Thereby, it is possible to swimmingly draw yarns Y.In addition, at this point, flier 132 is because of itself and rubber magnet The resistance of the magnetic force that is generated between iron plate 133 and the interrupted rotation relative to rotation accumulation roller 50, thus with no rubber The case where magnet plate 133, is compared, and the tension for being applied to the yarns Y of extraction is capable of increasing.

In addition, at this point, in initial extension yarn, yarn feeder 11 will be crossed on and be wrapped between 12 side of forming portion yarns Y It is hooked on the part 132b of flier 132.Yarns Y hangs yarn by flier 132 as a result,.Moreover, if making to rotate accumulation rolling in this state Cylinder 50 rotates, then the rotation of flier 132 and rotation accumulation roller 50 links and rotates, so that yarns Y is wound in rotation accumulation Roller 50.The extension yarn to rotation accumulation roller 50 is carried out as a result,.At this point, as described above, by flier 132 and rubber magnet iron plate The magnetic force generated between 133 applies the resistance for hindering the rotation relative to rotation accumulation roller 50, therefore flier to flier 132 132 reliably link with the rotation of rotation accumulation roller 50 and are rotated.Thereby, it is possible to reliably carry out to rotation accumulation roller 50 Extension yarn.

In addition, as shown in Figure 21 (a), Figure 21 (b), replacing the rubber in variation 8 in another variation (variation 9) Glue magnet plate 133, and part 132b of the end face setting with flier 132 by 12 side of forming portion is wrapped in the axial direction of flange 62 The resistance of contact applies brush 136 (" the first resistance applies brush " of the invention).It is brushed at this point, the flier 132 of rotation applies from resistance 136 power being subject to become the resistance for hindering flier 132 to rotate relative to rotation accumulation roller 50.

In addition, as shown in Figure 22 (a), Figure 22 (b), replacing the rubber in variation 8 in another variation (variation 10) Glue magnet plate 133, and apply 141 (this hair of brush in the resistance that the part 132b of flier 132 setting is contacted with the upper surface of flange 62 Bright " the second resistance applies brush ").At this point, the resistance for being set to the flier 132 of rotation applies the power that brush 141 is subject to from flange 62 As the resistance for hindering flier 132 mobile relative to rotation accumulation roller 50.

In addition, in variation 8~10, for example, it is also possible to make the front end of the part 132b of flier 132 to rotation accumulation Yarn for preventing from hanging over the front end of the part 132b of flier 132 is arranged in axial 11 side bending of yarn feeder of roller 50 etc. The part that line Y falls off.

In addition, in the example above, yarn limiting unit has and moving along guide rail along rotation accumulation roller 50 Outer peripheral surface is in the wire loop of rotation accumulation roller 50 moved up in week or by centered on the central axis for rotating accumulation roller Rotation and its front end along rotation accumulation roller 50 outer peripheral surface in rotation 50 weeks fliers moved up of accumulation roller, but not It is confined to this.Yarn limiting unit is also configured to, and is had and is configured to rotating along the outer peripheral surface of rotation accumulation roller 50 It moves up in the week of accumulation roller 50 and is configured to the yarn for being crossed on yarn feeder 11 and being wrapped between forming portion 12 Y hang the structures different from above structure in the extension yarn portion of yarn.

Moreover, yarn limiting unit is not limited to rotating with the outer peripheral surface for being configured to edge rotation accumulation roller 50 The structure in the extension yarn portion moved up in the week of accumulation roller 50.In another variation (variation 12), such as Figure 23 (a), Figure 23 (b) shown in, yarn limiting unit 150 has ring component 151.Ring component 151 is by CFRP (Carbon Fiber Reinforced Plastic: carbon fibre reinforced composite) etc. compositions circular component.In addition, ring component 151 throughout than rotation to store The mode of 2 weeks circumferential slightly shorter ranges (" than the range of 1 perimeter " of the invention) of roller 50 is stayed helically to be wound in rolling The end by 12 side of forming portion is wrapped in the axial direction of the vertical tube part 61d of cylinder main body 61.In addition, circumferential two of ring component 151 End is bent in such a way that the outside of the radial direction towards rotation accumulation roller 50 is curved respectively.In addition, being utilized in variation 12 The tapering 62a of flange 62 prevents ring component 151 from falling off from rotation accumulation roller 50.Moreover, from rotation accumulation roller 50 to package The yarns Y that 12 side of forming portion is drawn is by reaching thread guides 51 between ring component 151 and rotation accumulation roller 50.

At this point, contacting and being limited with ring component 151 from rotation accumulation roller 50 to the yarns Y that package 12 side of forming portion is drawn System movement.The yarns Y that thereby, it is possible to keep drawing, to prevent the yarns Y relaxation for being wound in rotation accumulation roller 50.

In addition, at this point, as shown in arrow A in Figure 23 (a), Figure 23 (b), will be crossed in initial extension yarn Yarns Y between yarn feeder 11 and package forming portion 12 is inserted into the ring helically wound from the end of a side of ring component 151 Gap 151a (" thread path " of the invention) between the overlapped part of component 151, and make the yarns Y of insertion along ring The circumferential direction of component 151 is mobile.Then, yarns Y is mobile according to the sequence of Y1, Y2, Y3 shown in double dot dash line in Figure 23 (a), from And it is imported into the inside of ring component 151 (between ring component 151 and rotation accumulation roller 50).Thereby, it is possible to carry out to ring component 151 extension yarn.Then, in this state, if making to rotate the rotation of accumulation roller 50, ring component 151 and rotation accumulation roller 50 It integrally rotates, so that yarns Y is wound in rotation accumulation roller 50 (carrying out the extension yarn to rotation accumulation roller 50).

In addition, ring component is not limited to the structure of variation 11.For example, ring component be also possible to it is different from variation 11 , the structure helically wound in a manner of the range throughout the 1 circumferential perimeter than rotation accumulation roller 50.Moreover, ring What component was not limited to helically to wind in a manner of the range throughout the 1 circumferential perimeter than rotation accumulation roller 50 Structure.Ring component is also possible to the yarns Y for having with for that will be crossed between yarn feeder 11 and above-mentioned package forming portion 12 The region more outward from the ratio ring component radially of rotation accumulation roller 50 imports its of the yarn access in the region of inside The structure that he constructs.

In addition, in another variation (variation 12), as shown in Figure 24, Figure 25 (a), Figure 25 (b), yarn limiting unit 155 have yarn limitation brush 156, and replace the guide rail 72 of the yarn limiting unit 63 of above embodiment, wire loop 73, contact plate 74, pressing plate 75 (referring to Fig. 5).Yarn limitation brush 156 is arranged in the outer peripheral surface of matrix 71 throughout its complete cycle.Moreover, from rotation The yarns Y that accumulation roller 50 is drawn to package 12 side of forming portion reaches yarn by the region configured with yarn limitation brush 156 Guiding piece 51.

At this point, the yarns Y drawn from rotation accumulation roller 50 to package 12 side of forming portion is because being hooked on yarn limitation brush 156 Hair and by limitation move.The yarns Y that thereby, it is possible to keep drawing, to prevent the yarns Y for being wound in rotation accumulation roller 50 Relaxation.

In addition, at this point, making to be crossed on yarn feeder 11 and the yarns Y being wrapped between 12 side of forming portion close to yarn when hanging yarn Limitation brush 156.Yarns Y is hooked on the hair of yarn limitation brush 156 as a result, and yarns Y is by extension yarn to yarn limitation brush 156.Moreover, In this state, if making to rotate the rotation of accumulation roller 50, yarn limitation brush 156 and rotation accumulation roller that yarns Y is hooked 50 integrally rotate, so that yarns Y is wound in rotation accumulation roller 50 (hanging yarn to rotation accumulation roller 50).

In addition, in the above-described embodiment, when making that formation movement stopping is wrapped, in the yarns Y of rotation accumulation roller 50 Accumulation amount be amount corresponding with lower limit Yarn senser 55b more than in the case where, make the rotation speed of winding drum 31 Vm1, rotation accumulation roller 50 yarns Y accumulation amount be it is fewer than amount corresponding with lower limit Yarn senser 55b and with it is most lower In the case where limiting the corresponding amount of Yarn senser 55c or more, the Vm2 for keeping the rotation speed ratio Vm1 of winding drum 31 slow, but simultaneously It is not limited to this.For example, it is also possible to be set as more subtly detecting the accumulation amount of the yarns Y of rotation accumulation roller 50, with rotation The reduction of the accumulation amount of the yarn of accumulation roller 50 and the rotation speed etc. for the winding drum 31 that slows down gradually.Alternatively, can also be Make be wrapped formation movement stop when, with rotation accumulation roller 50 yarns Y accumulation amount independently, make winding drum 31 with certain Rotation speed rotation.
