Strand Y is drafted by drafting assembly (not expression among the figure), props up through reciprocating traverse
Point volute guide wire 8 is batched by wind2 1.When batching, strand Y simultaneously back and forth drives by traversing apparatus 3, and one side is pushed down by friction roller 4 at the P point.
Bobbin 6 is installed on spool stand 5, and bobbin 6 is by friction roller 4 friction-driven, and therefore, the strand Y that is pushed down by friction roller 4 is wound into package 7 on bobbin 6.
Give prominence on the slide block 2 and be provided with frame 9, above-mentioned friction roller is installed on the frame 9 with freely rotating.Dispose traversing apparatus 3 above friction roller 4, the crank motion of strand Y is realized by traversing apparatus 3.
In addition, mechanism unit UL and the UR that constitutes traversing apparatus 3 is made up of upstream side traversing unit U1 and traversing unit, downstream U2 respectively.
Fig. 3 is the section-drawing of the main rotating part of one of reciprocating thread guide mechanism unit shown in Figure 2.
On upstream side traversing unit U1, be provided with and make the reciprocating fin 23,24 of strand Y, on the traversing unit in downstream U2, be provided with equally and make the reciprocating fin 25,26 of strand Y.
These fins 23～26 are respectively by by two groups of gear clusters 29,30,31 about bearing supporting, obtain driving and turn round.
In the end of frame 9, as shown in Figure 2, be provided with motor 43, this motor 43 turns round the gear 29 that is transferred to mechanism unit UL by gear 44, makes its revolution.Gear 29 so with gear 32 engagement of adjacency, this gear 32 further passes to power mechanism unit UR.
Be called the 1st traversing apparatus below the traversing unit U1(of upstream) the configuration of fin 23,24 can from reciprocating traverse, transport strand in the mind-set two ends.On the other hand, be called the 2nd traversing apparatus below the traversing unit U2(in downstream) fin 25,26 be configured to and can transport strand Y to the center from crank motion journey two ends.
As shown in Figure 4, traversing unit U1, U2 are respectively such configurations: the plane of rotation of fin 23～26 is with vertical by the formed plane of strand Y crank motion, perhaps the end of fin 23～26 tilt slightly downstream (tilting 30 ° in the present embodiment).
Guide plate 37(Fig. 2) be fixed on the unit U1, guide plate 38 is fixed on the unit U2.Shaped design at the guide plate track 37a that forms on the guide plate 37 becomes when strand Y is transported by fin 23,24, roughly keeps certain along the moving velocity of the reciprocating strand of this guide plate track 37a.
On the other hand, the shape of the guide plate track 38a that forms on the guide plate 38 is to set like this: when strand Y is transported by fin 25,26, at the reciprocating traverse central portion, with above-mentioned fin 23,24 speed about equally, and in the reciprocating traverse end, decelerate to moving velocitys gradually from 1.5～7 times of moving velocity by the strand Y of fin 23,24 guiding by the strand Y of fin 23,24, guiding.
In addition, the arrow of Fig. 2 is the gyratory directions of each fin of expression.
According to above structure, the strand Y that transports with fin 24 mind-set end from reciprocating traverse of the 1st traversing apparatus, one arrives the reciprocating traverse end, just the fin 26 of the 2nd traversing apparatus is given in handing-over, turn back to the reciprocating traverse center again, the fin of midway delivering by the 1st traversing apparatus 23 continues to transport, the strand one that transports by fin 23 arrives the reciprocating traverse end, the fin 25 of the 2nd traversing apparatus is given in handing-over again, turn back to the reciprocating traverse center once more, repeat like this, realize the reciprocating traverse effect.
In addition, the 1st with the fin 23,24 of the 2nd traversing apparatus and 25,26 spacing also can be identical.
Below, according to Fig. 4, Fig. 5, strand handover method when Fig. 6 describes traversing of the present invention in detail.
1. Fig. 4 represents the state that the fin 24 by the 1st traversing apparatus makes strand move to left-hand.Because fin 24, strand Y transports to left-hand with speed about equally from reciprocating traverse central authorities.Fin 24 1 arrives corners (2. state), just contacts with strand towards the fin 26 of rotating the 2nd traversing apparatus of dextrad.But fin 24 continues to transport strand Y left, and at this moment the dextrad moving velocity of the 2nd traversing apparatus fin 26 be 7 times of near 1. strand speed V (fin 26 speed can in 1.5～7 times the scope of strand speed V).
Strand Y is transported to such position by fin 24 always: the position compared with contact point that connects strand and friction roller with straight line and place, fin 24 places is come, the position of Y is also to the center position of reciprocating traverse bent position slightly, the guide plate track 37a of strand Y and upstream side reciprocating thread guide mechanism unit U1 contacts like this, breaks away from fin 24.
In order to make strand be case of bending slightly as mentioned above, the traverse S1 of the strand Y that is transported by fin 24 will satisfy:
S1≥S0+2L1 tgθ
Here, the traverse of the strand that contacts on the friction roller is made as S0, and the distance from fin 24 to the friction roller contact point is made as L1, and winding angle is made as θ.
In addition, the traverse S2 when fin 26 contacts with strand Y is set at, S2≤S0+2L2 tg θ.Here, L2 is the distance from fin 26 to the friction roller contact point.
The strand Y that breaks away from fin 24 from the position 2. 2. to the position that surpasses the winding angle commutation ', because fin 26 decelerates to the speed that is roughly V gradually from 7V speed, and as among Fig. 5 3. shown in, transport towards dextrad by fin 26.
Describe the situation that strand Y arrives reciprocating traverse end, above-mentioned left side in detail, shown in Fig. 6 (a), strand Y contact end is the 26a of minor flaps portion of the fin 26 of fork shape, this is because strand Y one breaks away from fin 24, just be subjected to the effect of inertia of strand Y, and strand Y breaking away from the moment tension force steep variation and become unstable of fin 24, therefore, and with the slot part 26b restriction strand of fin 26.Fin 25 also is same shape.This slot part 25b, 26b are located at the vertical of fin 25,26, and to the reciprocating traverse central part shown in Fig. 6 (b), it is controlling strand Y always from the reciprocating traverse end shown in Fig. 6 (a).
Fig. 6 (b) presentation graphs 5 is the situation of transporting of the strand Y of state 3., and Fig. 6 (c) presentation graphs 5 is the situation of transporting of the strand Y of state 4..
As Fig. 5 4. shown in, when strand Y was transported near the reciprocating traverse center, strand Y contacted with the fin 23 of the 1st traversing apparatus, fin 23 is located at the upstream side of the fin 26 of the 2nd traversing apparatus, is spaced from certain distance, strand with speed V fortune to right-hand.
Arrive near the extended line of the straight line that connects friction roller contact points and fin 26 when fin 23 after, the guide plate track 38a of the strand that is transported by fin 26 and fin 23 and the reciprocating thread guide mechanism unit U2 in downstream contacts (with reference to Fig. 6 (c)), strand Y breaks away from fin 26, as Fig. 5 5. shown in the state, by fin 23 fortune of the 1st traversing apparatus to right-hand.
Subsequently, strand Y arrives the reciprocating traverse end on right side, and the strand that fin 23 transports arrives corner (Fig. 4, the 6. state of Fig. 5), and it just contacts with the fin 25 of rotating the 2nd traversing apparatus left.At this moment, fin 23 is further towards the right-hand strand Y that transports, and in the bent position slightly than the linear position that connects friction roller contact point and fin 23, the guide plate track 37a of the reciprocating thread guide mechanism unit U1 of strand Y and upstream side contacts, and breaks away from fin 23.
As mentioned above, traverse S1 is set at: S1 〉=S0+2L1 tg θ, traverse S2 is set at: S2≤S0+2L2 tg θ.
The strand Y that breaks away from fin 23 and aforementioned 2., 2. ' the same, surmounting the oppositely directed position of winch spool, decelerate to the speed that is roughly V gradually by fin 25 from 7V speed, as 7. shown in the state of Fig. 4, transport to left.
As among Fig. 4 8. shown in the state, when strand Y transported near the reciprocating traverse center, strand Y just contacted with the upstream side of being located at fin 25, at a certain distance the fin 24 of the 1st traversing apparatus, and strand is transported by the speed of fin 24 with V.
The strand that transports by fin 25 and fin 24, arrive near the extended line of the straight line that connects friction roller contact points and fin 25 when fin 24 after, strand Y contacts with the guide plate track 38a of the reciprocating thread guide mechanism unit U2 in downstream, break away from fin 24, strand Y is as among Fig. 4 1. shown in the state, by fin 24 fortune to left.Strand speed during above-mentioned moving back and forth is set by the combination of shapes of fin 24,23 and guide plate track 37a, fin 25,26 and guide plate track 38a.
Then, above-mentioned handshaking is carried out repeatedly, forms package being installed on the bobbin of spool stand.
Below, the relation of transporting with regard to fin of the present invention between the package periphery hardness of the speed of strand and winding shaping explains.
For reduce strand irregular, package intensity is uprised, the difference of hardness of package periphery is preferably as far as possible little in whole package width.Therefore, among the present invention, fin is transported the speed of strand and study, the difference of hardness of package periphery is reduced.Below, this method is described.
Fig. 7 represents that traversing traverse and fin transport the relation between the strand speed, X-axis is represented traverse, and the speed (dotted line) that Y-axis is represented the 1st traversing is with respect to the speed ratio of the seal wire speed of reciprocating traverse central portion and the 2nd reciprocating wire spee (solid line) speed ratio with respect to the seal wire speed of reciprocating traverse central portion.A is illustrated in the oppositely directed position of winding angle, reciprocating traverse end.The hardness of the package periphery when Fig. 8 represents to batch strand with speed shown in Figure 7.
X-axis is represented the package width, and B represents the package end, and C represents the package center since about the relative center C of package hardness about equally, therefore only represent its left side.
Y-axis is represented the aviation value of 6 packages being measured with hardness meter (NAKAASA SOKKI makes yarn hardness) every 5mm from package B end.Because B is the package end face, hardness there can not be measured.Therefore it is identical with measured value apart from the point of B5mm to imagine it.
Batching on spindle driving type reeler of Fig. 8 carried out, and its condition of batching is: drawn polyester yarn, cross section 75 daniers/36 feet, 5600 meters/minute of coiling speeds, 6.8 ° of winding angles, batch contact pressure 16kg, tension force 14～16g, batch 6 packages on a spool stand.
The speed of Fig. 7 (a)～(c) expression the 1st traversing apparatus is constant speed roughly, and it is 2 times～7 multiplication speed that the speed of the 2nd traversing apparatus is risen by the end, decelerates to gradually then and crosses the A point; The package hardness of this moment is at Fig. 8 (a)～(c) representing accordingly.
(d)～(e) expression of Fig. 7 is in order further to make the package hardness difference diminish, at the package central portion, make the state of the speed deceleration of the 2nd traversing apparatus, Fig. 7 (d) has done 5% with respect to constant speed and has slowed down, Fig. 7 (e) has done 8% deceleration with respect to constant speed, and the package hardness of this moment is illustrated among Fig. 8 (d), (e) accordingly.
The speed that Fig. 7 (f) expression makes the 1st, the 2nd traversing apparatus is roughly batched the state of strand during constant speed, and the package hardness of this moment is represented in Fig. 8 (f).
The front has illustrated that the deceleration of package central portion speed realizes by the 2nd traversing apparatus, even but only also can access effect same by the 1st traversing apparatus or with the deceleration that the 1st, the 2nd traversing apparatus is made identical value.
Make fin 25 and 26 distance between shaftss bigger in the present embodiment, but also can be same distance than fin 23 and 24 distances.
(Fig. 2) in the present embodiment, the fin monolithic molding, but also can be shown in Fig. 9 (a) and Figure 10 (a), with support 40 and filar guide 41(pottery etc.) be made into two parts, fix with bolt 42.
In addition, shown in Fig. 9 (b) and Figure 10 (b), also can use rivet 43 or bolt support 40 and filar guide 41, and shoulder 40a is closed in establishing on support 40, so that bear centnifugal force.
Further, Fig. 9 (c) and Figure 10 (c) make support 40 and filar guide 41 respectively, with rivet 44 or bolt, the auxiliary section are designed to circle, to bear centnifugal force and location.
In addition, the two ends at the guide plate track of guide plate 38 as shown in figure 11, are provided with the lug boss 38b of stria 38c separately, make strand Y can insert the slot part of fin 25,26 reliably, simultaneously, can prevent to be extruded to Figure 11 below by the strand of fin 25,26 guiding.
Little at interval between the 1st traversing apparatus and the 2nd traversing apparatus (was 5～10mm) originally, strand will be dragged between the fin of two traversing apparatus and fin and be smoothed out with the fingers, strand can young pilose antler be taken place or percentage elongation is irregular, toward only past the strand quality is obviously reduced.Therefore, the interval between the 1st traversing apparatus and the 2nd traversing apparatus with 15mm～70mm for well.
In the present embodiment, describe, but bobbin also can be more than one or 2 with regard to the traversing apparatus that batches two packages on the spool stand.
In addition, up-coiler also can be the sutomatic winding machine that includes several spool stands.
In the present embodiment, fin 25,26 is provided with recess 26b,, also can not establish the 26c among Fig. 6, only establishes 26a.
According to above explanation, according to traversing apparatus of the present invention, even when high-speed wind-up, can access does not have chimb to have the package of good shaping yet, and it is irregular to prevent to batch the strand quality.
