Disclosure of Invention

As in the device of patent document 1, when the interlacing device is disposed between two non-heated rollers, the non-heated rollers located upstream of the interlacing device in the running direction of the yarn are wound with the yarn before the bundling property is imparted by the interlacing device. In such a case, at the upstream side non-heated roller, a problem occurs in that a part of the plurality of filaments constituting one filament is cut and wound around the roller due to friction with the roller or the like, resulting in yarn breakage.

On the other hand, when the yarn is disposed upstream of the plurality of heating rollers in the advancing direction of the yarn, the yarn having the bundling property imparted thereto by the yarn interlacing device is subjected to a heat treatment in the drawing section. The interlacing device winds a plurality of filaments constituting one filament at regular intervals. That is, in the drawing section, the filament in which the bundled portions in which the plurality of filaments are wound and the non-bundled portions which are not wound are alternately arranged in the filament traveling direction is heat-treated. In such a case, uneven heating occurs between the yarn winding portion and the non-winding portion, and there is a problem in that physical properties are degraded.

The utility model aims to provide a spinning traction device which can inhibit the physical property of a silk thread from being reduced and prevent the silk thread from being wound on a non-heating roller.

The spinning drawing device according to claim 1 draws a yarn composed of a plurality of filaments spun from a spinning device, and stretches the yarn while heating the yarn, and is characterized by comprising: at least one heating roller for heating the yarn; a non-heating roller, on which the yarn heated by the at least one heating roller is first wound; and an interlacing device disposed between the heating roller and the non-heating roller for conveying the filaments to the non-heating roller, and imparting bundling property to one of the filaments composed of a plurality of filaments.

In the present utility model, a yarn in a state of being given bundling by an interweaving device is wound on a non-heated roller on which the yarn heated by at least one heated roller is wound first. Thus, winding of the filament at the non-heated roller can be prevented. Further, since the yarn heat-treated by the heat roller is not given bundling property by the interlacing device, uneven heating of the yarn due to the bundled state of the yarn can be prevented, and deterioration of physical properties can be suppressed.

The spinning drawing device according to claim 2 is characterized by further comprising an incubator accommodating the heating roller, wherein the interlacing device is disposed outside the incubator.

When the interleaving device is disposed in the incubator, the temperature of the air in the incubator is lowered by the air blown out from the interleaving device, which may affect the heating process of the heating roller. Further, the surface temperature of the heating roller is lowered due to the air blown out from the interleaving device, and the power consumption is increased. In the present utility model, since the interweaving device is disposed outside the incubator, the heat treatment can be performed normally while suppressing a decrease in the temperature of the air in the incubator. Further, power consumption can be suppressed.

The spinning device 2 spins out the molten polymer as a plurality of filaments F. Each package P formed by the winding unit 6 is a package in which one multifilament yarn, i.e., yarn Y, composed of a plurality of filaments F is wound around 1 bobbin B.

The oil supply guide 3 is disposed below the spinning device 2. The oil supply guide 3 is provided corresponding to 1 yarn Y composed of a plurality of filaments F. Each oil feed guide 3 imparts an oil agent to the bundle-like filaments F.

A plurality of filaments Y to which the oiling agent is applied by the plurality of oil supply guides 3 are supplied to the stretching portion 4. The stretching unit 4 mainly includes 5 godet rolls 41 to 45 and an incubator 46. The plurality of filaments Y are guided to the drawing section 4 by the guide roller 11. In the drawing section 4, the plurality of filaments Y are drawn by 5 godets 41 to 45 while being heated. The plurality of filaments Y stretched by the stretching unit 4 are guided to the winding unit 6 by the guide rollers 12 to 14.

The 5 godet rolls 41 to 45 are each rotationally driven by a motor (not shown). In the present embodiment, the wire feeding speed of the godet rollers 41 to 43 is set to be slower than the wire feeding speeds of the godet rollers 44 and 45. The wire feeding speed of each godet 41 to 45 is not limited thereto. The rotation axes of the 5 godet rollers 41 to 45 are parallel to each other. The 5 godet rolls 41 to 45 are disposed in a posture in which their axes of rotation are parallel to the front-rear direction. In the drawing section 4, the yarn Y is wound around the 5 godets 41 to 45 at a winding angle of less than 360 degrees.

The godet 41 has a heater 41a inside. The godet 42 has a heater 42a inside. The godet 43 has a heater 43a inside. The godet 44 has a heater 44a inside. The godet 45 has a heater 45a inside. The 5 godet rolls 41 to 45 heat the yarn Y while conveying the yarn Y. The 5 godet rolls 41 to 45 correspond to "heating rolls" of the present utility model.

The incubator 46 houses 5 godet rolls 41 to 45. The incubator 46 is a substantially rectangular parallelepiped-shaped box. The incubator 46 is formed by a side wall in which a heat insulating material is enclosed. Thus, the heat emitted from the 5 godet rolls 41 to 45 is less likely to escape from the inside of the incubator 46 to the outside, and the inside of the incubator 46 is insulated.

A yarn inlet 46a for introducing a plurality of yarns Y into the incubator 46 is formed in the right side wall portion of the incubator 46. The yarn inlet 46a is an opening penetrating the right side wall of the incubator 46 in the right-left direction. The yarn inlet 46a is formed near the lower end of the right side wall of the incubator 46. A yarn outlet 46b for guiding the plurality of yarns Y from the inside of the incubator 46 to the outside is formed in the right side wall portion of the incubator 46. The yarn outlet 46b is an opening penetrating the right side wall of the incubator 46 in the right-left direction. The yarn guide-out port 46b is formed near the upper end of the right side wall portion of the incubator 46.

The plurality of wires Y guided by the guide roller 11 to the drawing section 4 are introduced into the incubator 46 through the wire introduction port 46a. As described above, the plurality of wires Y introduced into the incubator 46 are wound around the 5 godets 41 to 45 in order from the lower godet 41. The winding angle of the yarn is less than 360 degrees with respect to the 5 godets 41 to 45, respectively.

The plurality of wires Y introduced into the incubator 46 from the wire inlet 46a are stretched by the difference in wire feeding speed between the two godet rolls 43 and 44, and heated by the 5 godet rolls 41 to 45. Thereafter, the plurality of wires Y are led out of the incubator 46 from the wire outlet 46b. The plurality of wires Y led out of the incubator 46 are conveyed to the winding unit 6 by the guide rollers 12 to 14.

The guide rollers 11 to 14 are driven to rotate by motors (not shown). The guide rollers 11 to 14 each have no heater inside. The guide rollers 11 to 14 are unheated rollers. The guide roller 11 guides the plurality of filaments Y to which the oiling agent is applied by the plurality of oiling guides 3 to the drawing section 4. The guide rollers 12 to 14 guide the plurality of filaments Y stretched by the stretching unit 4 to the winding unit 6.

The guide roller 11 is disposed in a posture in which its rotation axis is parallel to the front-rear direction. The guide roller 11 is disposed on the right side of the incubator 46. The guide roller 11 is disposed near the yarn inlet 46a of the incubator 46. The guide roller 11 guides the plurality of wires Y into the incubator 46 through the wire introduction port 46a.

The guide roller 12 is disposed in a posture in which its rotation axis is parallel to the front-rear direction. The guide roller 12 is disposed on the right side of the incubator 46.

A plurality of wires Y fed by the godet 45 and led out of the incubator 46 from the wire outlet 46b are wound around the guide roller 12. That is, the guide roller 12 is wound on the first of the plurality of filaments Y heated by the 5 godets 41 to 45 at the stretching portion 4.

The guide rollers 13 and 14 are each disposed in a posture in which their rotation axes are parallel to the left-right direction. The guide rollers 13 and 14 are disposed on the right side of the incubator 46. The guide roller 13 is disposed below the guide roller 12. A plurality of wires Y fed from the guide roller 12 are wound around the guide roller 13. The guide roller 13 conveys the plurality of wires Y to the guide roller 14. The guide roller 14 is disposed at a position rearward and above the guide roller 13. A plurality of wires Y fed from the guide roller 13 are wound around the guide roller 14. The guide roller 14 conveys the plurality of wires Y to the winding portion 6.

The interlacing device 5 is disposed between the godet 45 and the guide roller 12. The interweaving device 5 is arranged outside the incubator 46. The interlacing device 5 blows air blown from a fluid jet nozzle (not shown) to a plurality of filaments F in a bundle.

The two spool holders 63 are respectively driven to rotate by motors (not shown). The rotation axes of the two bobbin holders 63 are parallel to each other. The two spool holders 63 are disposed in a posture in which the axial directions thereof are parallel to the front-rear direction. A plurality of bobbins B are mounted to each bobbin holder 63 along the axial direction thereof. When each bobbin holder 63 rotates, the plurality of bobbins B attached to the bobbin holder 63 also rotate integrally with the bobbin holder 63.

The rotation of the turntable 62 supporting the two bobbin holders 63 can switch the positions of the two bobbin holders 63 between the winding position (upper position in fig. 1) and the retracted position (lower position in fig. 1). That is, the turntable 62 switches the bobbin holder 63 that winds the yarn Y.

The plurality of fulcrum guides 64 and the plurality of traverse guides 65 are each mounted to the main body frame 61. The plurality of fulcrum guides 64 are disposed above the bobbin holder 63 at the winding position. The plurality of traverse guides 65 are arranged above the plurality of fulcrum guides 64. The plurality of fulcrum guides 64 and the plurality of traverse guides 65 are disposed in correspondence with the plurality of bobbins B, respectively. Each traverse guide 65 traverses the yarn Y hooked on the corresponding fulcrum guide 64.

The plurality of wires Y fed from the guide roller 14 are hooked to the plurality of fulcrum guides 64, respectively. The plurality of wires Y are wound around the plurality of bobbins B mounted on the bobbin holder 63 at the winding position while being traversed in the axial direction of the bobbins B by the plurality of traverse guides 65 centering on the corresponding fulcrum guides 64. Thereby, a plurality of packages P are formed on the plurality of bobbins B, respectively. In the wire winding, the contact roller 66 rotates while being in contact with the outer peripheral surface of the package P and applying a predetermined contact pressure, thereby adjusting the shape of the package P.

(features of the embodiment)

As described above, the spinning drawing device 1 according to the present embodiment draws the yarn Y composed of the plurality of filaments F spun from the spinning device 2, and stretches the yarn Y while heating the yarn Y.
