Patent Document 1: Japanese Patent Laid-Open Publication No. 2012-241941

In the spinning and pulling device described in Patent Document 1, when a plurality of multifilaments are wound around a plurality of heating rolls at an angle of inclusion within 360 degrees, the apparatus has a small size, and thus energy saving can be achieved, and the environment is excellent. Fig. 9 (a) is a view showing a spinning machine 100 in which a plurality of filaments Y3a, Y3b, ... are spun. 9(b) to 9(e) are cross-sectional views of a plurality of filaments wound around a godet 200, which is a heating roller. In Figs. 9(b) to (e), a plurality of filaments constituting one multifilament of a different thread type are respectively shown. In the conventional apparatus, for example, as shown in (b) of FIG. 9, a plurality of filaments Y3a, Y3b, ... constituting one multifilament are bundled, that is, wound as a filament bundle X3 on the godet 200. Further, the plurality of filaments Y3a, Y3b, ... are wound around the godet roller 200 in a state of being overlapped to some extent.

In the spinning and pulling device described in Patent Document 1, when the filament is wound around the godet at an angle of 360 degrees or less, the contact length of the filament with respect to one of the godet rollers is short, so that it is difficult to make the filament. The problem of rising to a predetermined temperature (for example, above the glass transition point). Figure 9 As shown in (b), when the filaments Y3a, Y3b, ... are thin, even if the filaments Y3a, Y3b, ... are slightly overlapped, the height of the filament bundle X3 in the radial direction of the godet roller is not so high. Therefore, there is no problem in the heating of the filament by the godet roller. Further, as shown in Fig. 9(c), when the number of the plurality of filaments Y4a, Y4b, ... is small, the filaments Y4a, Y4b, ... have a small degree of overlap, and therefore, the filament in the radial direction of the godet roller The height of beam X4 is also not that high. Therefore, there is no problem in the heating of the filament by the godet roller.

However, as shown in Fig. 9(d), when the filaments Y5a, Y5b, ... are thick, the height of the filament bundle X5 in the radial direction of the godet becomes high due to the overlap of the filaments Y5a, Y5b, ... . Further, as shown in Fig. 9(e), when the number of the plurality of filaments Y6a, Y6b, ... is large, the filament bundles X6 in the radial direction of the godet roller are overlapped by the overlapping of the filaments Y6a, Y6b, ... The height becomes higher. As described above, when the height of the filament bundle on the godet roller becomes high, the heat of the godet roller is hardly transmitted to the respective corners of the filament bundle, that is, the individual filaments, and therefore, the heating of the filament bundle becomes insufficient. . Here, when the device in which the filament is wound around the godet at an angle of inclusion within 360 degrees is applied to each of the multifilaments having a large number of filaments or a multifilament having a large number of filaments, by increasing the diameter of the godet, Or increasing the number of godet rolls ensures the length of contact of the filaments with the godet. However, this contradicts the miniaturization and energy saving of the above-described devices.

It is an object of the present invention to reliably heat a filament in a spinning retracting device having a heating roller on which a filament is wound, even for a multifilament having a large number of multifilaments or a plurality of filaments. .

In the spinning and pulling device according to the first aspect of the invention, the plurality of multifilament yarns spun from the spinning machine are separately drawn and wound, and the spinning and pulling device includes a plurality of godet rollers including a heating roller. The plurality of godet rollers are used for stretching and heat treatment, and have restricting means upstream of the traveling direction of the multifilament of the heating roller, the restricting means having a plurality of guiding portions for dividing one multifilament into The filament bundle is guided by two or more filament bundles, and the filament bundles respectively limiting the integral number of the winding packages are respectively provided, and a yarn joining means is provided on a downstream side of the heating roller in the traveling direction of the multifilament yarn. The wire means is for combining the plurality of filament bundles obtained by stretching the plurality of godet rolls into one of the plurality of multifilaments.

In the conventional spinning traction device, a plurality of filaments constituting one multifilament are wound around a heating roller by a bundle of filaments. In the present invention, the plurality of filaments constituting one multifilament are respectively wound around a plurality of rollers including a heating roller on the basis of a plurality of filament bundles divided into two or more by a restriction means. Therefore, compared with the case where a plurality of filaments constituting one multifilament are wound around the heating roller with one filament bundle, the number of filaments constituting the filament bundle wound around the heating roller is small, so that the diameter of the heating roller can be suppressed. The height of the upward filament bundle. Therefore, the heat generated by the heating roller is easily transmitted to the filaments constituting the filament bundle, so that the heating efficiency of the filament of the heating roller is improved. Further, since the heating of the filament can be made more reliable, the quality of the multifilament is improved. Further, since the heating efficiency of the filament is improved, the temperature of the filament is improved, and the filament can be raised to a predetermined temperature even if the length of contact of the filament with respect to the heating roller is short.

According to a second aspect of the invention, in the spinning and pulling device of the first aspect of the invention, the filament bundle traveling on the godet roller is in contact with the godet roller at an angle of inclusion within 360 degrees.

In the present invention, since the heating efficiency of the filament is improved, the temperature of the filament is improved, and the filament can be raised to a predetermined temperature even if the contact length between the filament and the heated godet is short. Thus, the apparatus capable of winding the filaments around the heating godet at an angle of 360 degrees or less can be applied to a multifilament having a large number of filaments or a multifilament having a large number of filaments.

According to a third aspect of the invention, in the spinning and pulling device of the second aspect of the invention, the plurality of guide portions for restricting the plurality of filament bundles are arranged at a predetermined interval. The plurality of filament bundles traveling on the heating roller do not overlap each other.

In the present invention, the plurality of guiding portions by the restricting means restrict the interval of the adjacent filament bundles so that the respective adjacent filament bundles of the plurality of godet rollers including the plurality of heating rollers do not overlap. Therefore, the separate filament bundles are heated by the heating rolls, so that the heating efficiency of the filaments is further improved.

According to a fourth aspect of the invention, in the spinning and pulling device of the second aspect of the invention, the restricting means restricts forming the two filament bundles wound around the multifilaments of the different wound packages a spacing between the two of the plurality of guiding portions is greater than a limit of two adjacent filament bundles respectively defining the two or more filament bundles of the one multifilament wound around one of the wound packages The spacing between the two aforementioned guides.

Forming a plurality of filament bundles of a multifilament as long as it does not generate a large The interval of the degree of overlap may be arranged on a plurality of rollers. On the other hand, it is preferable that the adjacent two filament bundles forming one multifilament which are different from each other are spaced as far as possible so as not to be entangled. However, when the interval is too large, a plurality of rollers become long. In the present invention, the guiding portion of the restricting means restricts the interval of the adjacent filament bundles so that the intervals of the adjacent two filament bundles of one multifilament which are different from each other on each of the plurality of rollers are larger than The spacing of adjacent two filament bundles forming a multifilament. Thus, it is sufficiently ensured that the intervals of adjacent filament bundles of one multifilament which are different from each other are formed, thereby preventing the filament bundles adjacent to each other from being formed from being twisted together. On the other hand, the interval between the plurality of filament bundles forming the same one multifilament is suppressed to be small, so that the plurality of godet rollers including the heating roller do not become long.

According to a fifth aspect of the invention, in the spinning and pulling device of the first aspect of the invention, the plurality of filaments that are wound around one of the multifilaments of the wound package are formed from the spinning machine. A polymer is supplied by a polymer flow path connected by a polymer metering means.

In the present invention, a plurality of filaments constituting one multifilament formed from a polymer supplied from a polymer flow path connected to one outlet of the polymer metering unit of the spinning machine are divided into two or more The filament bundles are then combined into one multifilament. Therefore, even if the number of the plurality of filaments constituting the filament bundle is slightly different in each filament bundle, it can be combined into one multifilament without any problem.

In the spinning and pulling device according to any one of the first to fifth aspects of the present invention, the spinning apparatus of the present invention further includes the plurality of filament bundles before stretching which are spun from the spinning machine. Oil agent for oil segment.

In the present invention, an oil agent is applied to a plurality of filament bundles before stretching which are spun from a spinning machine by an oil agent supply means. The filament bundle is obtained by dividing a plurality of filaments constituting one multifilament into two or more strips. Therefore, the number of filaments constituting the filament bundle is small, so that the oil agent is easily and uniformly attached to each filament.

In the present invention, a plurality of filaments constituting one multifilament are divided into two or more filament bundles by a restriction means, and are respectively wound around a plurality of rollers including a heating roller. Therefore, the number of filaments constituting the filament bundle wound around the heating roller is small as compared with the case where a plurality of filaments constituting one multifilament are wound around the heating roller by one filament bundle. Therefore, with respect to the above plurality of filaments, the height of the radial filament bundle of the heating roller can be suppressed. Therefore, the heat generated by the heating roller is easily transmitted to the respective filaments constituting the filament bundle, so that the heating efficiency of the filament of the heating roller is improved. Moreover, since the heating of the filament can be made more reliable, the quality of the multifilament is improved. Further, since the heating efficiency of the filament is improved, the temperature rise of the filament is improved, and the filament can be raised to a predetermined temperature even if the contact length of the filament with respect to the heating roller is short.

The plurality of filaments Y1a, Y1b, ... spun from the spinning machine 100 are in a state of being a bundled filament bundle X1. Further, the plurality of filaments Y2a, Y2b, ... travel downward in a state in which the bundled filament bundles X2 are formed. That is, one filament bundle X1 is composed of a plurality of filaments Y1a, Y1b, ..., and one filament bundle X2 is composed of a plurality of filaments Y2a, Y2b, .... Further, in the drawing, only a part of the plurality of filaments Y1a, Y1b, ... constituting one filament bundle X1 is numbered, and only a plurality of filaments Y2a, Y2b, ... constituting one filament bundle X2 are... Some of them are labeled, and other reference numerals are omitted.

The cooling device 2 is a device for cooling a plurality of filament bundles X1, X2 spun from the spinning machine 100. The cooling device 2 cools the filament bundles X1 and X2 by, for example, blowing cooling air toward the filament bundles X1 and X2. The cooling device 2 is disposed below the spinning machine 100. Also, the cooling device 2 is provided for one spinning machine 100.

The refueling nozzle 3 is a device that applies an oil agent to the two filament bundles X1 and X2 cooled by the cooling device 2. The refueling nozzle 3 is disposed below the cooling device 2. Further, the refueling nozzle 3 is provided in the same manner as the cooling device 2 for one spinning unit 101, that is, for each of the two filament bundles X1 and X2. Therefore, one of the refueling nozzles 3 applies an oil agent to the filament bundle X1, and the other refueling nozzle 3 applies an oil to the filament bundle X2.

Fig. 3 (a) is a front view of the fueling nozzle 3. Fig. 3(b) is a cross-sectional view taken along line B-B of Fig. 3(a). Here, it means long The tow X1 (a plurality of filaments Y1a, Y1b, ...) is supplied to the oiling nozzle 3 of the oil agent. The fueling nozzle 3 has a guide groove 33 that extends in the vertical direction and guides a plurality of filaments Y1a, Y1b, ... spun from the spinning machine 100 in the front side portion (the front side portion of the paper surface of Fig. 3(a)). Further, a supply hole 34 connected to the supply portion outside the drawing is formed in the rear side portion of the fueling nozzle, and the tip end of the supply hole 34 is opened in the guide groove 33. The oil agent supplied from the supply unit is supplied from the supply hole 34 to the inside of the guide groove 33. In the guide groove 33, a plurality of liquid storage tanks 35 are formed side by side. Each of the liquid storage tanks 35 has a horizontally long shape, and both end portions thereof extend to the side faces of the guide grooves 33. The oil supplied from the supply hole 34 into the guide groove 33 is expanded to the entire inner surface of the guide groove 33.

When the plurality of filaments Y1a, Y1b, ... are guided downward by the guide groove 33, the oil in the guide groove 33 adheres to the plurality of filaments Y1a, Yb, .... Further, since the oil agent is held in the liquid storage tanks 35 of a plurality of horizontally long shapes, the oil agent is easily and uniformly adhered to the plurality of filaments Y1a, Y1b, ... traveling in the guide grooves 33. For the filament bundles X1, X2 after the oil agent is supplied from the fueling nozzle 3, the wire passage guide 20 is bent toward the inner side.

The plurality of godet rollers 4 to 8 are members disposed along the wire passage for stretching a plurality of multifilament yarns Y (filament bundles X1, X2). The plurality of godet rollers 4 to 8 are driving rollers that are rotated by a motor (not shown) supported by a frame (not shown), and have heaters inside. The godet rolls 4 to 6 are pre-heating godet rolls for pre-heating the filament bundles X1 and X2 before stretching by the filament bundles X1 and X2 before stretching. Preheating guide The wire rolls 4 to 6 are set to, for example, a temperature of 80 to 100 °C. In order to perform stretching, it is necessary to set the temperatures of the plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... to be above the glass transition temperature. Therefore, in the case of polyester fibers, it is necessary to use a godet for preheating. heating. In addition, the glass transition temperature varies depending on the polymer. The godet rolls 7, 8 are heat setting godet rollers for heat setting the stretched filament bundles X1, X2. The godet rollers 7, 8 for heat setting are set to a temperature of, for example, 120 to 150 ° C in the case of polyester fibers.

The rotation axes of the plurality of godet rollers 4 to 8 extend in the depth direction of the paper surface of FIG. 1, and the respective axes are substantially parallel to each other. Further, the diameters of the plurality of godet rollers 4 to 8 are, for example, in the range of 220 to 300 mm, and are substantially the same diameter. The zigzag rollers 4, 5, 6, 7, and 8 are arranged in a zigzag manner from the bottom. The godet rollers 7, 8 for heat setting are disposed at positions above the godet rollers 4 to 6 for preheating. On the godet rollers 4-8, the guide rollers at a lower angle of 360 degrees are respectively directed from the lower guide roller toward the upper guide roller, that is, in the order of the godet rollers 4, 5, 6, 7, 8. The filament bundles X1, X2 are wound.

The plurality of godet rollers 4 to 8 are disposed inside the incubator 11. The incubator 11 is a box having a substantially rectangular parallelepiped shape formed of a heat insulating material. The heat from the plurality of godet rollers 4 to 8 is prevented from escaping to the outside by the incubator 11. On the incubator 11, slits 12, 13 are provided below and above the same side. The filament bundles X1, X2 enter the interior of the incubator 11 through the slit 12 below. Further, the filament bundles X1 and X2 are led out from the inside of the heat insulating box 11 through the slit 13 above.

The filament bundles X1, X2 spun from the spinning machine 100 are fed by the guide rolls 14 to the most upstream pre-heating godet rolls 4. Here, the rotation axis of the guide roller 14 extends in the depth direction of the paper surface of FIG. Further, the direction of the rotation axis of the guide roller 14 and the arrangement direction (left-right direction) of the spinning unit 101 are shifted by 90 degrees. The filament bundles X1, X2 spun from the spinning machine 100 are rotated by 90 degrees and guided to the guide rolls 14, and are wound side by side in the direction of the rotation axis of the guide rolls 14. Similarly, in the plurality of godet rollers 4 to 8 whose axes are substantially parallel to the axis of the guide roller 14, the filament bundles X1 and X2 are wound side by side in the direction of the rotation axis.

The process of stretching the filament bundles X1, X2 will be described. The filament bundles X1, X2 are preheated to a temperature above the glass transition point by contact with the godet rollers 4 to 6 for preheating. The preheated filament bundles X1, X2 are fed to the downstream heat setting godet rolls 7, 8 by the rotation of the preheating godet rolls 4-6. Here, for example, the wire feed speeds (speeds at which the filament bundles X1 and X2 are transported downstream) of the upstream pre-heating godet rolls 4 to 6 are substantially the same. Further, the wire feeding speeds of the downstream heat guiding godet rolls 7, 8 are substantially the same, and the wire conveying speed is faster than the godet rollers 4 to 6 for preheating. Therefore, the filament bundles X1 and X2 are stretched between the godet rollers 4 to 6 for preheating and the godet rollers 7 and 8 for heat setting which are faster than the godet rollers 4 to 6. The stretched filament bundles X1, X2 are heat-set by contact with the godet rollers 7, 8 for heat setting, and are conveyed toward the guide roller 15 by the rotational driving of the godet rollers 7, 8 for heat setting. .

The complexing device 9 imparts a complexation to the two filament bundles X1 and X2 stretched by the plurality of godet rollers 4 to 8 to form a single multifilament Y. through The stretched two filament bundles X1, X2 are conveyed by the guide roller 15 from the plurality of godet rollers 4 to 8 toward the intersecting device 9.

After the two filament bundles X1 and X2 stretched by the plurality of godet rollers 4 to 8 are combined into one multifilament yarn Y by the intersecting device 9, the winding device 10 winds the multifilament yarn Y to form a winding. Package P. The winding shaft of the winding device 10 extends horizontally in the depth direction of the paper surface, and has a bobbin holder 16 in which a plurality of bobbins B are assembled in series along the axial direction of the winding shaft (in the depth direction of the paper surface), and the bobbin holder is provided 16 rotating motor (not shown).

The winding device 10 rotates the bobbin holder 16 by the driving of the motor to rotate the plurality of bobbins B attached to the bobbin holder 16. A plurality of multifilament yarns Y are wound around a plurality of rotating bobbins B to form a plurality of winding packages P. Further, when the plurality of winding packages P attached to the bobbin holder 16 are fully loaded, they are pushed forward by a pusher (not shown) and are removed from the bobbin holder 16. As described above, the winding device 10 winds one multifilament Y by a plurality of bobbins B attached to the bobbin holder 16, and forms a plurality of winding packages P in parallel.

In the prior art apparatus, a plurality of filaments constituting a multifilament yarn spun from a spinning pack are wound as a filament bundle on a godet roller. In this way, when a multifilament having a large number of filaments and a multifilament having a large number of filaments are produced, the height of the radial filament bundle of the godet roller becomes high. Therefore, there is a problem that the heating efficiency of the filament bundle is poor, it is difficult to heat the filament bundle to a predetermined temperature, and it is difficult to produce a multifilament having a large number of filaments or a multifilament having a large number of filaments.

In the present embodiment, a plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... which are formed by spinning a single multifilament Y from the spinning machine 100 are divided into two filament bundles X1, X2, and on this basis Above 360 degrees The inner surrounding angle is wound around a plurality of godet rollers 4-8. Further, the two filament bundles X1 and X2 stretched by the plurality of godet rollers 4 to 8 are wound after being combined into one multifilament yarn Y.

4 is a cross-sectional view of the filament bundles X1, X2 wound around the godet roller 4. As shown in Fig. 4, on the godet roller 4, a plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... which are spun from the spinning machine 100 and constitute a multifilament Y are divided into two filament bundles. Rolling is performed on the basis of X1 and X2. Therefore, compared with the case where a plurality of filaments constituting one multifilament are wound around a godet by a filament bundle (a bundle of filaments indicated by a broken line in Fig. 4), the composition of the godet 4 is long. The plurality of filaments Y1a, Y1b, ... of the tow X1 and the plurality of filaments Y2a, Y2b, ... constituting the filament bundle X2 are small in number, and therefore, the filament bundle X1 in the radial direction of the godet roller 4 can be suppressed. The height of the X2. Therefore, the heat generated by the godet roller 4 is easily transmitted to the filaments Y1a, Y1b, ... constituting the filament bundle X1 and the filaments Y2a, Y2b, ... constituting the filament bundle X2, and therefore, on the godet roller 4 The heating efficiency of the plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... is improved.

Further, in Fig. 4, when a plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... constituting one multifilament Y are divided into two filament bundles X1, X2 and wound around a godet, Since the heating of the filament bundles Y1a, Y1b, ..., Y2a, Y2b, ... is more reliably performed, the quality of the multifilament Y is improved. Further, since the heating efficiency of the filaments Y1a, Y1b, ..., Y2a, Y2b, ... is improved, the temperature rise of the filaments Y1a, Y1b, ..., Y2a, Y2b, ... is good. Therefore, even if the filaments Y1a, Y1b, ..., Y2a, Y2b, ... are in contact with each of the godet rollers 4-8, The degree is short, and it is also possible to raise Y1a, Y1b, ..., Y2a, Y2b, ... to a predetermined temperature. Therefore, even when the filaments Y1a, Y1b, ..., Y2a, Y2b, ... are wound around the godet rollers 4 to 8 at an angle of inclusion within 360 degrees, it is possible to produce multifilaments and filaments each having a thick filament. A large number of multifilaments.

Further, one godet roller 4 has been described in Fig. 4, but the other godet rollers 5 to 8 are also treated in the same manner. Specifically, a plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... which are spun from the spinning machine 100 and which constitute a multifilament yarn Y are wound on the basis of being divided into two filament bundles X1, X2. .

Here, in the present embodiment, the plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... constituting one multifilament Y are divided into a plurality of filaments Y1a, Y1b spun from the nozzle group 106 on the left side, ... and spun from the two sets of the filaments Y2a, Y2b, ... spun from the nozzle group 107 on the right side. Therefore, the plurality of filaments Y1a, Y1b, ... form a bundle of filament bundles X1. Further, the plurality of filaments Y2a, Y2b, ... form a bundle of filament bundles X2. The plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... constituting one multifilament Y are divided into two filament bundles X1, X2 and stretched. Here, the polymer supplied from one polymer flow path 102 connected to one output pipe of a polymer metering pump (not shown) is a plurality of nozzles Y as a plurality of filaments Y1a, Y1b, ..., Y2a, Y2b, ... Spinning out. Therefore, in the present embodiment, a plurality of filaments Y1a, Y1b of a multifilament Y composed of a polymer supplied from one polymer flow path 102 connected to one output pipe of a polymer metering pump (not shown) is formed. , ..., Y2a, Y2b, ... are divided into two filament bundles X1, X2. Further, the above-mentioned filament bundles X1 and X2 are bundled 9 (corresponding to the method of the present invention) is combined into a multifilament Y. Therefore, the number of the plurality of filaments Y1a, Y1b, ... constituting the filament bundle X1 and the number of the plurality of filaments Y2a, Y2b, ... constituting the filament bundle X2 do not need to be strictly the same amount, even if they are slightly different It doesn't matter.
