Abstract

Damage on yarns is restrained while allowing the bending angles of the yarns at distribution guides by which the yarns spun out from a spinning unit are distributed to be large. Yarns 10 serially spun out and supplied from a spinning machine are conveyed to a winding unit below by two godet rollers, and in a winding unit the yarns 10 are distributed by fulcrum guides 13 and then wound onto bobbins attached to a bobbin holder. Each fulcrum guide 13 is a column having a radius of not shorter than 3mm and not longer than 8mm, and the yarn 10 is threaded on the outer circumference of the fulcrum guide 13. By rotating the fulcrum guide 13, the sliding position between the fulcrum guide 13 and the yarn 10 is changed. Furthermore, the movement of the yarn 10 threaded on the fulcrum guide 13 is restrained in the axial directions of the fulcrum guide 13, because the yarn 10 is arranged to pass through a slit 25a made through a restraining guide 25 which is provided above the fulcrum guide 13.

godet rollers

11,12 can be bearing on the framework 14 the axle center 7a quadrature of its

axle center

11a, 12a and coil holder 7 as shown in Figure 1 rotatably above the body frame 5 of winder unit 3.Godet

roller

11,12 is the driven roller that is driven by not shown drive motors.Godet roller 11 be configured in spinning machine 2 under.Godet roller 12 is configured in axially the departing from the position of godet roller 11 at coil holder 7 of godet roller 11 tops.

And godet roller 12 is by moving in the Filament winding position above the substantial middle that is positioned at a plurality of fulcrum guide 13 orientations (position that the solid line of Fig. 1 represents) and between than the Filament winding position string-up position near godet roller 11 (position that the double dot dash line of Fig. 1 represents) on the lower such as the elevating mechanisms such as linear motor 16.

A plurality of fulcrum guides 13 along the axle center 7a of coil holder 7 with identical being spaced in interval at the center in the axial direction of a plurality of bobbin B be configured in than the godet roller 12 in the downstream that is positioned at the Filament winding position on the lower, top, a plurality of traverse motion threadguide 8 of a plurality of traverse motion threadguide 8 and be installed in a plurality of bobbin B on the coil holder 7 directly over.

A plurality of fulcrum guides 13 as Fig. 2～shown in Figure 4 have along extend with the horizontal direction of the axial quadrature of coil holder 7 (prescribed direction of intersecting with the axle of coil holder 7), radius R is the cylindrical shape below the above 8mm of 3mm, the silk thread 10 of sending here from godet roller 12 is hung on the outer peripheral face of fulcrum guide 13.That is, fulcrum guide 13 with the sliding surface of silk thread 10 on radius of curvature below the above 8mm of 3mm.

And fulcrum guide 13 is formed by for example ceramic material, and such as Fig. 2～shown in Figure 4, its root end is installed on the thread guide support unit 21.And volume hangs with conveyer belt 22 respectively on the thread guide support unit 21 corresponding with adjacent 2 fulcrum guides 13 in a plurality of fulcrum guides 13.And, with be configured in outermost 2 fulcrum guides 13 in a corresponding thread guide support unit 21(in Fig. 3, be configured in the thread guide support unit 21 of top side (being the rightmost side among Fig. 1, Fig. 2)) a side opposite with adjacent thread guide support unit 21, be provided with belt wheel 23, also volume hangs with conveyer belt 22 between this thread guide support unit 21 and belt wheel 23.Belt wheel 23 is installed on the motor 24, when drive motor 24 rotates belt wheel 23, utilize conveyer belt 22 and a plurality of thread guide support units 21 of being connected to each other and the fulcrum guide 13 that is installed on these thread guide support units 21 rotate centered by axially by it.And when fulcrum guide 13 rotated, sliding position fulcrum guide 13 and silk thread 10 changed.That is the structure that, in this example conveyer belt 22, belt wheel 23 and motor 24 is combined is equivalent to consist of sliding position of the present invention and changes mechanism, thread guide rotating mechanism of the present invention.

Implemented the processing that makes silk thread 10 be easy to slide with the friction of silk thread 10 in order to reduce on the outer peripheral face of the fulcrum guide 13 that wherein, slides with silk thread 10.But if identical long-time and silk thread 10 slips of part of the outer peripheral face of fulcrum guide 13, then the above-mentioned processing of this part of fulcrum guide 13 is just deteriorated.

Therefore in this example, by fulcrum guide 13 being rotated to change fulcrum guide 13 and sliding position silk thread 10, can prolong thus the life-span of fulcrum guide 13 as mentioned above.In addition, the change with sliding position silk thread 10 fulcrum guide 13 just makes fulcrum guide 13 turn an angle to carry out by the action that for example whenever makes take-up winding 1 carry out the stipulated time.

And, because a plurality of thread guide support units 21 and the belt wheel 23 usefulness conveyer belts 22 that are installed on the motor 24 are being connected to each other, if drive motor 24, belt wheel 23 and a plurality of fulcrum guide 13 rotate, and therefore the sliding position with silk thread 10 of a plurality of fulcrum guides 13 are changed.

And, above adjacent each fulcrum guide 13, be respectively arranged with restriction guide 25, restriction guide 25 be formed with along coil holder 7 extend axially and at the slit 25a of the medial extremity opening of Fig. 2.Hang over silk thread 10 on the fulcrum guide 13 through disposing in the 25a of slit, with the wall restriction of the slit 25a movement to axial (prescribed direction) of fulcrum guide 13.Thus, can prevent that silk thread 10 from coming off from fulcrum guide 13.

And in the take-up winding 1 with above structure, as shown in Figure 1, a plurality of silk threads of providing from spinning machine 2 10, are at first arranged volume along the axle center 11a of godet roller 11 and are hung to the below by conveyance.Then roll up a plurality of silk threads 10 limits that hang on the godet roller 11 and walk abreast the oblique upper end bay around being positioned on the locational godet roller 12 of Filament winding.And a plurality of silk threads 10 that volume hangs on the godet roller 12 are distinguished repieces to a plurality of fulcrum guides 13, are bent at fulcrum guide 13, and conveyance is to the winder unit 3 of below.

Wherein, when silk thread 10 when crooked on fulcrum guide 13, as shown in Figure 5, on silk thread 10, apply pressure of contact surface F from fulcrum guide 13, the winding angle θ of 10 pairs of fulcrum guides 13 of silk thread (angle of bend of silk thread 10) is larger, and this pressure of contact surface is larger.And pressure of contact surface F is larger, and the damage that silk thread 10 is subject to becomes larger.

On the other hand, to be positioned at higher position at the godet roller 12 of silk thread 10 being given fulcrum guide 13 then less for winding angle θ.Therefore, reduce winding angle θ (becoming for example below 15 °) if godet roller 12 is configured in high position, then silk thread 10 also diminishes from the pressure of contact surface F that fulcrum guide 13 is subject to, and can alleviate the damage of silk thread 10.But, if godet roller 12 is configured in high position, then brought the maximization of device.

And, the radical of the silk thread 10 that provides from spinning machine 2 has the tendency that becomes many in recent years, in the corresponding situation that a plurality of fulcrum guides 13 are set, greatly away from godet roller 12, the winding angle θ of silk thread 10 on the fulcrum guide 13 in the outside becomes large at the axial superolateral fulcrum guide 13 of coil holder 7.Therefore, reduce winding angle θ if godet roller 12 is configured in high position, then the radical of silk thread 10 is more, more has godet roller 12 is configured in high locational necessity, and device large-scale changed into large problem.

Therefore, even in this example when having increased winding angle θ (for example about 30 °), by diminishing for the pressure of contact surface F that silk thread 10 is subject to from fulcrum guide 13 and fulcrum guide 13 being become the cylindrical shape that outer peripheral face becomes the sliding surface of silk thread 10, can increase the radius of curvature on fulcrum guide 13 and sliding surface silk thread 10.

But if winding angle θ is identical, then the radius R of fulcrum guide 13 (with the radius of curvature on the sliding surface of silk thread 10) is larger, and is silk thread 10 just longer with length fulcrum guide 13 slippers.Therefore if make the radius R of fulcrum guide 13 excessive, the damage that then silk thread 10 is subject to the slip of fulcrum guide 13 just becomes large.

Namely, during the winding angle θ of the silk thread 10 on having increased fulcrum guide 13, the damage that is subject in order to suppress as small as possible silk thread 10 has to take into account the necessity that the radius R of fulcrum guide 13 (with the radius of curvature on the sliding surface of silk thread 10) is set in appropriate scope with the length of fulcrum guide 13 slippers that imposes on the pressure of contact surface F of silk thread 10 and silk thread 10 from fulcrum guide 13.

Therefore, consider these factors in this example, in order to suppress as possible the damage that silk thread 10 is subject to, the radius R that makes the fulcrum guide 13 of cylindrical shape is more than the 3mm, below the 8mm.Thus, even reduce, increase in the situation of winding angle θ in the position with godet roller 12, also as described below, can do one's utmost to suppress the damage that 13 pairs of silk threads 10 of fulcrum guide cause.

[embodiment]

Then use Fig. 6 that embodiments of the invention are described.The figure of the result of the test of the silk thread physical characteristic mensuration of silk thread 10 when Fig. 6 distributes the spinning Y that sends here from godet roller 12 for expression with the fulcrum guide 13 of various radius Rs, that carry out in the downstream of fulcrum guide 13.Wherein, so-called silk thread physical characteristic represent stretch bending silk thread 10 situations under the ratio of tensile stress and the tensile stress when not having silk thread 10 fracture in crooked silk thread 10 situations that stretches during silk thread 10 fracture, this value is higher, and it is less to be illustrated in the damage that fulcrum guide 13 place's silk threads 10 are subject to.And, Fig. 6 has represented to make silk thread 10 to be the multifilament of polyester material FDY, 150de, the winding angle θ that makes the silk thread 10 at fulcrum guide 13 places is 30 °, making the speed of travel of silk thread 10 is 4800m/min, the experimental result when making thread tension than the top trip sides part of fulcrum guide 13 be 0.25gr/de.Wherein, in order to make the positively durable use in after this etc. of the silk thread 10 that is wound up on the bobbin B, preferably make the physical characteristic of silk thread more than 90%, from the result of Fig. 6 as can be known, if make the radius R of fulcrum guide 13 more than the 3mm, below the 8mm, then can guarantee the silk thread physical characteristic more than 90%.

In addition, the situation when although Fig. 6 has represented that winding angle θ is 30 °, but winding angle θ than 30 ° of little situations under, if the radius R of fulcrum guide 13 is identical, compare when being 30 ° with winding angle θ, pressure of contact surface F is little, and length silk thread 10 and fulcrum guide 13 slippers are short, so the damage of silk thread 10 is little when being 30 ° than winding angle θ.Therefore, though winding angle θ than 30 ° of little situations under, if the radius R that makes fulcrum guide 13 then can be guaranteed the silk thread physical characteristic more than 90% more than the 3mm, below the 8mm.And, even in the situation different from above-mentioned example such as the kind of silk thread 10, thickness, speed of travel, if winding angle θ is 30 °, then be speculated as the silk thread physical characteristic identical with above-mentioned experimental result.

Then explanation has applied the variation of all changes to this example.But for the structure identical with this example, suitably the description thereof will be omitted.

Connect 2 adjacent thread guide support unit 21(fulcrum guides 13 with conveyer belt 22 in the above-mentioned example) and connect respectively outermost thread guide support unit 21 and be installed in belt wheel 23 on the motor 24 with conveyer belt 22, by the positions of sliding with silk thread 10 that motor 24 rotation can be unified change fulcrum guide 13, but be not limited to this.

For example, also can hang on all the thread guide support unit 21 and belt wheel 23 across volume by a conveyer belt.Perhaps, also can motor be set respectively to a plurality of fulcrum guides 13, fulcrum guide 13 can be rotated individually.

And, also be not limited to by fulcrum guide 13 being rotated change fulcrum guide 13 and sliding position silk thread 10.A variation (variation 1) arranges cylinder 30 in a side opposite with the top of fulcrum guide 13 as shown in Figure 7, and the piston rod 31 of cylinder 30 is installed on the end of an opposite side with the top of fulcrum guide 13.So when the air pressure of the inner space 32 that changes cylinder 30 with not shown pump etc., piston rod 31 and fulcrum guide 13 be moving axially along fulcrum guide 13 integratedly.Be specially, fulcrum guide 13 moves to axial top one side when making the pressure rises of inner space 32, moves to butt one side when air pressure is descended.

So, moving along its axis by making like this fulcrum guide 13, the positions of sliding with silk thread 10 that can change fulcrum guide 13 can prolong life-span of fulcrum guide 13 thus.That is, cylinder 30 is equivalent to consist of the thread guide of the present invention travel mechanism that sliding position of the present invention changes mechanism in the variation 1.

Wherein, although with cylinder 30 fulcrum guide 13 is moved along its axis in the variation 1, be not limited to cylinder 30 fulcrum guide 13 is moved along its axis, also can the fulcrum guide be moved along its axis with oil hydraulic cylinder or other mechanism.

And, as being used for changing fulcrum guide 13 and mechanisms silk thread 10 sliding positions, although above-mentioned example only is provided with mechanism's (conveyer belt 22, belt wheel 23 and motor 24) that fulcrum guide 13 is rotated, variation 1 only is provided with mechanism's (cylinder 30) that fulcrum guide 13 is moved along its axis, but also can these mechanisms both arrange.In this case, the life-span of fulcrum guide 13 becomes longer.

And although be provided with to change mechanism fulcrum guide 13 and sliding position silk thread 10 in the above example, such mechanism does not arrange passable yet.

And, although above-mentioned example is provided with restriction silk thread 10 and from the restriction guide 25 that fulcrum guide 13 comes off, is used for preventing that silk thread 10 is not limited to this from the mechanism that fulcrum guide 13 comes off along moving axially of fulcrum guide 13 above fulcrum guide 13.For example, also can prevent that in large other structure that waits of diameter change of its top ends silk thread 10 from coming off from fulcrum guide 13 with fulcrum guide 13.

And, at fulcrum guide 13 along its axial long enough, even silk thread 10 is along in the situation that moves axially also not the worry that comes off from fulcrum guide 13 of fulcrum guide 13, as described abovely be used for preventing that silk thread 10 is also passable from the structure that fulcrum guide 13 comes off.

And, although above-mentioned example central bearing point guide 13 have along extend with the direction of the axial quadrature of coil holder 7, outer peripheral face becomes and the cylindrical shape of the sliding surface of silk thread 10, fulcrum guide 13 also can extend along the direction of intersecting with coil holder 7 axial, tilt with respect to the direction with the axial quadrature of coil holder 7.And the fulcrum guide is not limited to cylindrical shape, also can be that radius of curvature on the sliding surface with silk thread 10 is in other shape more than the 3mm, below the 8mm.And the radius of curvature on the fulcrum guide and sliding surface silk thread 10 also can be not necessarily, and every part is different.
