And, in this example, swing the 1st conveying roller 23 is moved by making to have configured the oscillating deck 22 of the 1st conveying roller 23, arm 41,42, axle 43 and electrical motor 44 part are altogether equivalent to mobile unit of the present invention.So such mobile unit can form with comparalive ease.

The 2nd conveying roller 24 is configured on the left surface of framework 21, the leading section of the part of extending along fore-and-aft direction of approximate L font, can centered by the axle A3 extending along left and right directions (parallel with wireline reel), rotate by the electrical motor 52 being configured on the right flank of framework 21.And by the 2nd such conveying roller 24 is separately positioned in multiple supply units 20, thereby these multiple the 2nd conveying rollers 24 are arranged along left and right directions.

And as mentioned above, be axle A3 because the oscillating axle of oscillating deck 22 is the same with the S. A. of the 2nd conveying roller 24, therefore compare with the inconsistent situation in position of these two axles, it is simple that the structure of supply unit 20 becomes.

Filar guide 25 (the 1st filar guide) is configured in the upper end of the part of extending along the vertical direction of the left surface of framework 21, approximate L word shape.Filar guide 26 (the 2nd filar guide) be configured in framework 21 left surface, be positioned in the part of the 2nd conveying roller 24 belows.

Cross winding unit 27 be configured in framework 21 left surface, filar guide 25 and in the part between the 1st conveying roller 23 of the 1st position.Cross winding unit 28 be configured in framework 21 left surface, between the 1st conveying roller 23 and the 2nd conveying roller 24 of the 1st position.

Cross winding unit 27,28 possesses respectively 61 and 2 filar guides 62 of interlacing device.Interlacing device 61 is configured in the substantial middle position of cross winding unit 27,28, has the silk thread walking space 61a for give cross winding to the silk thread Y of walking and is used for the silk thread of silk thread Y insertion silk thread walking space 61a to insert gap 61b.2 filar guides 62 are configured in the both sides of interlacing device 61, have the silk thread installing space 62a that silk thread is installed.

And silk thread inserts the mutually same side opening of gap 61b and silk thread installing space 62a, cross winding unit 27 makes these openings come configuration ventrally, and cross winding unit 28 makes these openings come upside to configure.

Silk thread guide member 29 is configured in part left surface, contiguous the 1st conveying roller 23 fronts of oscillating deck 22, integrally swings by swing and the 1st conveying roller 23 of oscillating deck 22.As described later, the parts of silk thread guide member 29 for guiding silk thread to use carry out repiece in yarn feeding device 1 time.

Anticreep filar guide 30 starts to extend to left from the part of top of the 2nd conveying roller 24 of the left surface that is positioned at framework 21, and rearward warpage of way therein.Anticreep filar guide 30 is as described later for preventing that in the time that supply unit 20 carries out repiece silk thread Y is from the come off parts of use of the 2nd conveying roller 24.

So, in the yarn feeding device 1 with this structure, as shown in FIG. 1 to 3, in each supply unit 20, spun the silk thread Y coming by spinning machine 2 from top and be arranged on filar guide 25, cross winding unit 27, cross winding unit 28, filar guide 26, and be wound around on the 1st conveying roller 23 and the 2nd conveying roller 24 that is positioned at the 1st position.

Thus, silk thread Y is transferred successively on filar guide 25, cross winding unit 27, the 1st conveying roller 23 that is positioned at the 1st position, cross winding unit 28, the 2nd conveying roller 24 and filar guide 26, is then transported to below towards filament winding device 3.Now, the 1st conveying roller 23 and the 2nd conveying roller 24 be with mutually different speed rotations, utilizes the tension force of the silk thread Y that the velocity contrast adjustment of the 1st conveying roller 23 and the 2nd conveying roller 24 is transferred.In addition, the path that this silk thread Y is transferred is equivalent to conveying Yong Si of the present invention road.

So, in this example, keeping being transported to filament winding device 3 by yarn feeding device 1 state of arrangement in parallel owing to spinning from spinning machine 2 the silk thread Y coming under the state of arrangement parallel to each other, therefore do not having direction the earth bending to the left and right on the way.Thus, can prevent the quality decline of silk thread Y.

And, because silk thread Y rolls up and is suspended on the 1st conveying roller 23 after having been given cross winding by cross winding unit 27, the silk thread Y that therefore can prevent from being wound around on the 1st conveying roller 23 is attached on the 1st conveying roller 23 dispersedly, thus, can prevent on silk thread Y circumvolution to the 1 conveying roller 23.

And, because silk thread Y is wound around on the 2nd conveying roller 24 after having been given cross winding by cross winding unit 28, then carry towards filament winding device 3, therefore can prevent from being winding in filament winding device 3 silk thread Y on bobbin B at random.

The following describes the step of carrying out repiece in yarn feeding device 1 (supply unit 20).Fig. 6 A～Fig. 6 D is the figure that represents the step of carrying out this repiece.In addition, below the repiece operation of explanation is undertaken by the operator who stands in yarn feeding device 1 front.

In order to carry out repiece in yarn feeding device 1, by being swung, oscillating deck 22 make the 1st conveying roller 23 move to above-mentioned the 1st position in advance, in this state, silk thread Y volume is not suspended to as shown in Figure 6A on the 1st conveying roller 23 and attaches it on filar guide 25,26.But, now partly installing between the part of extending along left and right directions of silk thread Y process anticreep filar guide 30 and the 2nd conveying roller 24.

In addition, under the state of Fig. 6 A the path one of silk thread Y process be silk thread Y be not equivalent to repiece Yong Si road involved in the present invention towards the path of filar guide 26 from filar guide 25 via the 1st conveying roller 23, in this example, make above-mentioned the 1st position and the 2nd position clip this repiece to come mutually a contrary side with Si Dao and set configuration, the pendulum angle of oscillating deck 22 etc. of the each several part of supply unit 20.

Then as shown in Fig. 6 B, Fig. 6 C, make the 1st conveying roller 23 move to the 2nd position from above-mentioned the 1st position by oscillating deck 22 is swung, then as shown in Figure 6 D, make in the opposite direction oscillating deck 22 swing, thereby make the 1st conveying roller 23 get back to above-mentioned the 1st position.

Fig. 7 A, Fig. 7 B are the figure that sees the 1st conveying roller 23 and silk thread guide member 29 from the direction of the arrow VII of Fig. 2, situation when Fig. 7 A represents the 1st conveying roller 23 is moved from from the 1st position to the 2nd position, situation when Fig. 7 B represents the 1st conveying roller 23 is moved from the 2nd position to the 1st position.

In addition, in Fig. 7 A, Fig. 7 B, make the direction of arrow VII and the swing of oscillating deck 22 is consistent centered by axle A3, swings, its above-below direction is 1st conveying roller 23 of oscillating deck 22 while having swung and the moving direction of silk thread guide member 29, and downside is the 1st position one side, upside is the 2nd position one side.

As shown in Figure 7 A, 7 B, outstanding towards left from the left side of oscillating deck 22 of silk thread guide member 29.And the face of upside tilts to below in figure toward the part in left side is offside in Fig. 7 A, Fig. 7 B of silk thread guide member 29, and, at least on left and right directions with the overlapping part of the 1st conveying roller 23 than the 1st conveying roller 23 in the drawings above give prominence to.

And the bottom of the face of the upside in Fig. 7 A, Fig. 7 B of silk thread guide member 29 in same figure is connected with the face in the left side of silk thread guide member 29.The face in the left side of silk thread guide member 29 from this connecting portion to figure lower left extend, and halfway to lower right warpage in figure, the lower end in its figure is arranged in the below of figure than the 1st conveying roller 23.

In addition, in this example, in the figure of silk thread guide member 29, the face in upside and left side is equivalent to guide surface of the present invention.

On the other hand, the face of the downside in Fig. 7 A, Fig. 7 B of silk thread guide member 29 is included on left and right directions the part overlapping with the 1st conveying roller 23, the part of having removed its left part is arranged in figure top than the 1st conveying roller 23.

So, in the time that the 1st conveying roller 23 is moved from the 1st position to the 2nd position, as shown in Fig. 6 B, Fig. 6 C, Fig. 7 A, silk thread Y contacts to the face of the top upside that give prominence to, Fig. 7 A of Fig. 7 A with ratio the 1st conveying roller 23 of silk thread guide member 29, is moved to by this face guiding the side keeping left than the 1st conveying roller 23.

If start to make the 1st conveying roller 23 and silk thread guide member 29 to continue to move to the 2nd position one side (top of Fig. 7 A) from this state, silk thread Y is guided by the face in the left side of silk thread guide member 29, come the lower end in the figure of this face, then leave silk thread guide member 29, under the effect of the tension force of silk thread Y, get back to original position.Thus, silk thread Y comes a contrary side with respect to the 1st conveying roller 23.

Thus and thus, in the time making the 1st conveying roller 23 move to the 2nd position from the 1st position, silk thread guide member 29 utilize above-mentioned guide surface make to be positioned at silk thread Y on repiece Yong Si road from the left (side) of the 1st conveying roller 23 around entering, be directed to a side contrary with respect to the 1st conveying roller 23.

Now, although the part that is positioned at the 2nd conveying roller 24 tops of silk thread Y also moves to left to a certain degree, by contacting with the part of extending along fore-and-aft direction of anticreep filar guide 30, can prevent from coming off from the 2nd conveying roller 24.

In addition, the amount of movement that is positioned at the part above the 2nd conveying roller 24 of silk thread Y is less than the length of the 2nd conveying roller 24 on left and right directions, because silk thread Y can not come off from the 2nd conveying roller 24, therefore anticreep filar guide 30 is not set passable yet.

On the other hand, as shown in Fig. 6 D, Fig. 7 B, in the time that the 1st conveying roller 23 has been moved from the 2nd position to the 1st position, silk thread Y is positioned at the top of Fig. 7 B than the 1st conveying roller, do not contact with the face of the downside in Fig. 7 B of silk thread guide member 29, contact with the 1st conveying roller 23.So, when start to make the 1st conveying roller 23 and silk thread guide member 29 further to move to the 1st direction one side (below of Fig. 7 B) from this state, silk thread Y is pushed and moves by the 1st conveying roller 23, and final the 1st conveying roller 23 moves to the 1st position, and silk thread Y is configured in and carries on Yong Si road.

Now, silk thread Y is respectively from the close cross winding unit 27,28 of coming in front and top, but because the silk thread insertion gap 61b of cross winding unit 27 and the silk thread insertion gap 61b of silk thread installing space 62a and cross winding unit 28 and silk thread installing space 62a have mouth in front side and upside (seeing repiece Yong Si road one side from carrying Yong Si road) respectively as mentioned above, therefore silk thread Y automatically inserts gap 61b from the silk thread of cross winding unit 27,28 and is inserted into silk thread walking space 61a, and is installed in silk thread installing space 62a.

As shown in Fig. 1～Fig. 3, Fig. 6 D, in yarn feeding device 1 (supply unit 20), carry out repiece by above such step.

Wherein, this example owing to arranging separately respectively the 1st conveying roller 23 and the 2nd conveying roller 24 with respect to silk thread Y as mentioned above in yarn feeding device 1, and therefore each the 1st conveying roller 23 and the 2nd conveying roller 24 become small-sized.Thus, can the 1st conveying roller 23 and the 2nd conveying roller 24 be rotated with the electrical motor of smaller type 51,52.And, because the 1st conveying roller 23 and the 2nd conveying roller 24 are small-sized, therefore need not make framework 21 and special maximization of oscillating deck 22 just can support the 1st conveying roller 23 and the 2nd conveying roller 24.Due to above reason, can make yarn feeding device 1 integral miniaturization.

And, owing to respect to multi-filament line Y, the 1st conveying roller 23 being set separately respectively, and arrange along left and right directions, therefore in the time making as described above the 1st conveying roller 23 move to the 2nd position from the 1st position, utilize silk thread guide member 29 can make silk thread Y from the left side of the 1st conveying roller 23 around entering, be directed to a side contrary with respect to the 1st conveying roller 23.

Therefore, as long as carry out as described above after silk thread Y being installed on filar guide 25,26, make the 1st conveying roller 23 move to the 2nd position from the 1st position, return the 1st such action in position, just can easily in yarn feeding device 1 (supply unit 20), carry out repiece.

And, in this example, even if silk thread guide member 29 is not set, as shown in Fig. 6 C the 1st conveying roller 23 is moved under the state of the 2nd position, make silk thread Y through the rear of the 1st conveying roller 23 silk thread Y is installed on filar guide 25,26, then by making the 1st conveying roller 23 move to the 1st position from the 2nd position, also can equally with this example in supply unit 20, carry out repiece.

But, now because being positioned to clip, the 2nd position and the 2nd conveying roller 24 carry out a repiece Yong Si road contrary side mutually, therefore in the time that silk thread Y is installed on filar guide 25, the 1st conveying roller 23 is located at the front of yarn feeding device 1 to carry out between the operator and filar guide 25 of operation, as a result 23 one-tenth of the 1st conveying rollers obstacle, repiece operation becomes and is difficult to carry out.

And in this example owing to being provided with silk thread guide member 29, therefore can, the 1st conveying roller 23 being configured in respect to repiece under the 1st locational state with Si Dao and the 2nd conveying roller 24 phase the same sides, multifilament be installed on filar guide 25,26 as shown in Figure 7 A.Thus, by silk thread Y when installing on filar guide 25,26, the 1st conveying roller 23 can not become obstacle, the repiece operation in supply unit 20 becomes easier.

And, in the time making as described above the 1st conveying roller 23 move to the 1st position from the 2nd position, because silk thread Y is automatically installed in cross winding unit 27,28, therefore making the 1st conveying roller 23 move to the 1st position from the 2nd position, needn't carry out again silk thread Y to be installed to the operation in cross winding unit 27,28, become easier toward carrying out repiece in yarn feeding device 1.

Then, the variation that has applied all changes on this example is described.But, add identical Reference numeral for the part with the structure identical with this example, and suitably the description thereof will be omitted.

In above-mentioned example, adopt carry out repiece in supply unit 20 time, when making the 1st conveying roller 23 silk thread Y when the 1st position is got back in the 2nd position be automatically installed to the structure cross winding unit 27,28, but silk thread that also can interlacing device 61 insert the silk thread installing space 62a of gap 61b, filar guide 62 opening towards different from this example, make the 1st conveying roller 23 from the 1st position is got back in the 2nd position, operator is by being manually installed to silk thread Y in cross winding unit 27,28.

And, in above-mentioned example, respectively carrying between filar guide 25 in Yong Si road and the 1st conveying roller 23 and be provided with cross winding unit 27,28 between the 1st conveying roller 23 and the 2nd conveying roller 24, but also can only configure in cross winding unit 27,28.Or, also can cross winding unit be set the place different from above-mentioned example in conveying Yong Si road.

For example, in a variation as shown in Fig. 8 A～Fig. 8 D, the part of extending along the vertical direction of framework 21 extends to more closer to the top than filar guide 25, and cross winding unit 27 is configured in the top (carrying the part of top trip one side of ratio filar guide 25 in Yong Si road) of filar guide 25.Now, carry out repiece in yarn feeding device 1 time, first make the 1st conveying roller 23 move to the 1st position, as shown in Figure 8 A silk thread Y is installed in cross winding unit 27 at such state, and be installed to filar guide 25,26 on the same with above-mentioned example.So, the same with above-mentioned example, as shown in Fig. 8 B～Fig. 8 D, make the 1st conveying roller 23 move to the 2nd position from the 1st position, then get back to the 1st position, by carrying out repiece like this in yarn feeding device 1.

Wherein, silk thread Y volume not being suspended on the 1st conveying roller 23, attaching it under the state in filar guide 25,26, as shown in Figure 8 A, silk thread Y contacts with the 2nd conveying roller 24.But now because silk thread Y is installed in cross winding unit 27, therefore silk thread Y contacts with the 2nd conveying roller 24 after having been given cross winding by cross winding unit 27.Therefore can prevent that silk thread Y from attaching on the 2nd conveying roller 24, can prevent on silk thread Y circumvolution to the 2 conveying rollers 24 thus.

And, in above-mentioned example, silk thread guide member 29 is configured on the face in left side of oscillating deck 22, but silk thread guide member 29 is just passable as long as having the parts of the guide surface that silk thread Y is directed to a side contrary with respect to the 1st conveying roller 23 in the time making the 1st conveying roller 23 move to the 2nd position from the 1st position, and its shape, size etc. are not limited to above-mentioned example.

And silk thread guide member 29 can not have yet.Now also can as described above the 1st conveying roller 23 be configured under the 2nd locational state and silk thread Y be installed on filar guide 25,26, if then make the 1st conveying roller 23 move to the 1st position from the 2nd position, just can in supply unit 20, carry out repiece.

And, although configured the oscillating deck 22 of the 1st conveying roller 23 in above-mentioned example for swing the parts that are freely being supported centered by the axle A3 identical with the S. A. of the 2nd conveying roller 24, the S. A. of the oscillating axle of oscillating deck 22 and the 2nd conveying roller 24 is inconsistent also passable.

And, although use in above-mentioned example and be connected to the oscillating deck 22 that arm on oscillating deck 22 41,42, axle 43, electrical motor 44 made to configure the 1st conveying roller 23 and swing, by making like this 1st conveying roller 23 swing between the 1st position and the 2nd position, but it is also passable by other structure, the 1st conveying roller 23 to be swung between the 1st position and the 2nd position.

And, the 1st conveying roller 23 is not limited to the structure that can swing centered by certain oscillating axle, also can be for example can be mobile etc. between the 1st position and the 2nd position along the guide rail extending point-blank, can be on the path different from above-mentioned example between the 1st position and the 2nd position the structure of movement.

And the 1st conveying roller 23 can be to be also fixed on the 1st locational structure.Now also because the 1st conveying roller 23 is distinguished separately and arranged with respect to multi-filament line Y, arrange along the direction parallel with its S. A., if after therefore in silk thread Y is installed to filar guide 25 and cross winding unit 27, make silk thread Y from the left side of the 1st conveying roller 23 around entering, roll up to be suspended to the 1st conveying roller 23, be installed to again in cross winding unit 28, and volume is suspended on the 2nd conveying roller 24, is finally installed in filar guide 26, just can in supply unit 20, carry out repiece.

And, due to now in the time that silk thread Y volume is suspended on the 1st conveying roller 23, can make as mentioned above silk thread Y from the left side of the 1st conveying roller 23 around entering, silk thread Y around to rear, is therefore become to easy toward the repiece in yarn feeding device 1.

And, although in above-mentioned example the 1st conveying roller the 23, the 2nd conveying roller 24 both arrange separately respectively with respect to multi-filament line Y, can be also the rectangular roller extending continuously across multi-filament line Y for the 2nd conveying roller 24.

Now also owing to respect to multi-filament line, the 1st conveying roller 23 being set separately respectively, therefore with make the 1st conveying roller 23 for extend continuously across multi-filament line rectangular roller time compared with, do not need large-scale electrical motor, be used for large-scale supporting member of anvil roll etc., correspondingly can make yarn feeding device 1 miniaturization.

In addition, even if the 2nd conveying roller 24 is rectangular roller, by with above-mentioned the same make silk thread Y from the left side of the 1st conveying roller 23 around entering, can easily carry out toward the repiece in yarn feeding device 1.
