Abstract
An oil supply guide and a spinning draft device are provided, which can uniformly supply oil to yarns even if the viscosity of the oil is low. The surface of the front side of the guide body of the oil supply guide extends in the up-down direction. The surface is formed with a discharge port for discharging the oil agent. Two yarn guide members extending in the vertical direction and inclined with respect to the vertical direction such that the interval therebetween becomes narrower as it goes downward are disposed at both left and right side portions of the discharge port on the surface. The portion of the surface located below the lower end of the discharge port is a lower curved surface curved so as to be convex toward the front side. When viewed from the left-right direction, neither a tangent line at the upper end of the discharge port and an upper portion of the guide body above the upper end, nor a straight line formed by rotating the tangent line by 10 ° in a direction approaching the upper end of the discharge port around the lower end of the discharge port, overlap each other.
Description
Technical Field
The present invention relates to an oil supply guide for applying an oil to a yarn spun from a spinning device, and a spinning draft device provided with the oil supply guide.
Background
The oil supply guide described in patent document 1 is an oil supply guide for applying an oil to a yarn spun from a spinning device. The oil supply guide of patent document 1 includes: an outlet for discharging the oil agent; and a contact surface for contacting the filament. The contact surface has: a 1 st curved surface formed with a discharge port; and a 2 nd curved surface located below the 1 st curved surface. The yarn starts to contact the contact surface at the peripheral edge portion of the discharge port, and at a predetermined position of the 2 nd curved surface, the yarn is separated from the contact surface by traveling in a tangential direction at the position.
Patent document 1: japanese patent laid-open publication No. 2016 and 216838
Here, the fueling guide of patent document 1 may be formed in a shape in which the upper end of the discharge port protrudes forward from the lower end due to manufacturing errors and the like. In this case, the wire starts to contact the contact surface at a portion near the upper end of the discharge port, and a gap is formed between the wire and the 2 nd curved surface. The oil agent discharged from the discharge port is accumulated in the gap, and the oil agent accumulated in the gap is applied to the yarn. In this case, when the viscosity of the oil agent is low, the oil agent tends to flow down from the gap, and the amount of the oil agent in the gap tends to vary with time. As a result, the yarn may have uneven adhesion (uneven adhesion) of the oil agent.
Disclosure of Invention
The invention aims to provide an oil supply guide capable of uniformly providing oil to a silk thread even under the condition of low viscosity of the oil, and a spinning traction device with the oil supply guide.
The oiling guide according to claim 1 is a guide for applying a finish to a yarn comprising a plurality of filaments spun from a spinning device, and comprises: a guide body having a surface extending along a 1 st direction; a discharge port formed in the surface of the guide body and discharging the oil; and two yarn guide members which are disposed on the surface of the guide body so as to be positioned on both sides of the discharge port in a 2 nd direction orthogonal to the 1 st direction, extend so as to narrow a mutual interval in the 2 nd direction as going from one side of the 1 st direction to the other side, and guide a plurality of yarns toward a center side in the 2 nd direction of the discharge port, the surface of the guide body having a contact surface for yarn feeding contact which is positioned on the other side than the discharge port in the 1 st direction, the contact surface being a curved surface which is curved so as to project toward an outer side of the guide body, an end portion on the one side of the discharge port in the 1 st direction and a portion of the guide body on the one side of the end portion on the one side of the discharge port in the 1 st direction being positioned on the one side than the end portion on the one side of the discharge port in the 1 st direction as viewed from the 2 nd direction, and does not overlap with a tangent line of the curved surface at the other end of the discharge port in the 1 st direction.
In contrast to the present invention, a case is considered in which, when viewed from the 2 nd direction, an end portion on one side of the discharge port in the 1 st direction or a portion of the guide body on one side of the end portion on one side of the discharge port in the 1 st direction overlaps a tangent line of the curved surface at a position of an end portion on the other side of the discharge port in the 1 st direction. In this case, when the fueling guide is disposed so that the wire is advanced from one side to the other side in the 1 st direction and the wire is brought into contact with the surface of the fueling guide at the peripheral edge portion of the discharge port, the portion of the wire near the end portion on the one side of the discharge port in the 1 st direction is brought into contact with the surface of the guide body. Thus, a gap can be formed between the curved surface and the wire. Further, the oil agent discharged from the discharge port is accumulated in the gap, and the oil agent accumulated in the gap is applied to the yarn. However, when the viscosity of the oil agent is low and the amount of oil agent discharged per unit time is small, there is a concern that: the oil agent does not stay in the gap for a long time but easily flows down, so that the amount of the oil agent in the gap is unstable, and unevenness in adhesion (uneven adhesion) of the oil agent occurs in the yarn.
In the present invention, when viewed from the 2 nd direction, the end portion on one side of the discharge port in the 1 st direction and the portion of the guide body on one side of the end portion on one side of the discharge port in the 1 st direction do not overlap with the tangent line of the curved surface at the position of the end portion on the other side of the discharge port in the 1 st direction. Therefore, when the oil feeding guide is disposed so that the wire is advanced from one side to the other side in the 1 st direction and the wire is brought into contact with the surface of the guide body at the peripheral edge portion of the discharge port, the portion of the wire near the end portion of the other side of the discharge port in the 1 st direction comes into contact with the curved surface. This prevents a gap in which the oil agent is accumulated between the curved surface and the yarn or a gap which is very small even if a gap is formed. As a result, the finish can be uniformly applied to the yarn even when the viscosity of the finish is low.
Further, in the present invention, since the contact surface is a curved surface, the wire in contact with the curved surface is separated from the curved surface by advancing in a tangential direction at a portion on the other side of the other end of the discharge port. Therefore, the oil agent is not scraped off by the corner when the wire is separated from the curved surface. This makes it possible to appropriately control the amount of finish applied to the yarn.
The fueling guide according to claim 2 is the fueling guide according to claim 1, wherein, in the fueling guide according to claim 1, the one end portion of the discharge port in the 1 st direction and a portion of the guide body closer to the one end portion of the discharge port than the one end portion of the discharge port in the 1 st direction do not overlap with a straight line in which the tangent line is inclined by 10 ° in a direction approaching the one end portion of the discharge port in the 1 st direction with the other end portion of the discharge port in the 1 st direction as a center, as viewed in the 2 nd direction.
The oil supply guide may be disposed such that a tangent to a contact surface at the position of the other end of the discharge port in the 1 st direction is slightly inclined with respect to the running direction of the yarn. In the present invention, when viewed from the 2 nd direction, the one end portion of the discharge port in the 1 st direction and the portion of the guide body on the one side of the one end portion of the discharge port in the 1 st direction do not overlap with a straight line in which the tangent line is inclined by 10 ° in a direction approaching the one end portion of the discharge port in the 1 st direction with the other end portion of the discharge port in the 1 st direction as a center. Thus, even if the oil guide is disposed such that the tangent line is inclined in a range of 10 ° or less with respect to the advancing direction of the thread, the thread starts to contact the curved surface at a portion near the other end of the discharge port in the 1 st direction, and a gap in which the oil agent is accumulated is not formed between the curved surface and the thread or is minute even if a gap is formed.
The oiling guide according to claim 3 is a guide for applying an oiling agent to a yarn comprising a plurality of filaments spun from a spinning device, and comprises: a guide body having a surface extending along a 1 st direction; a discharge port formed on the surface of the guide body and discharging an oil agent; and two yarn guide members arranged on the surface of the guide body so as to be positioned on both sides of the discharge port in a 2 nd direction orthogonal to the 1 st direction, extending so that a mutual interval in the 2 nd direction becomes narrower as going from one side to the other side in the 1 st direction, and guiding a plurality of yarns toward a center side in the 2 nd direction of the discharge port, the surface of the guide body having a contact surface for yarn feeding contact, the contact surface having a plane forming an end portion on the other side of the discharge port in the 1 st direction, the end portion on the one side of the discharge port in the 1 st direction and a portion of the guide body on the one side of the end portion on the one side of the discharge port in the 1 st direction being viewed from the 2 nd direction, not overlapping with the 1 st extension plane formed by extending the plane.
In contrast to the present invention, a case is considered in which, when viewed from the 2 nd direction, an end portion on one side of the discharge port in the 1 st direction or a portion of the guide body on one side of the end portion on one side of the discharge port in the 1 st direction overlaps the 1 st extension surface. In this case, when the fueling guide is disposed so that the wire is advanced from one side to the other side in the 1 st direction and the wire is brought into contact with the surface of the fueling guide at the peripheral edge portion of the discharge port, the portion of the wire near the end portion on the one side of the discharge port in the 1 st direction is brought into contact with the surface of the guide body. Thus, a gap can be formed between the plane and the wire. Further, the oil agent discharged from the discharge port is accumulated in the gap, and the oil agent accumulated in the gap is applied to the yarn. However, when the viscosity of the oil agent is low and the amount of oil agent discharged per unit time is small, there is a concern that: the oil agent does not stay in the gap for a long time but easily flows down, so that the amount of the oil agent in the gap is unstable, and the oil agent is unevenly adhered to the yarn (uneven adhesion).
In the present invention, when viewed from the 2 nd direction, the end portion on the discharge port side in the 1 st direction and the portion of the guide body on the side closer to the end portion on the discharge port side in the 1 st direction do not overlap the 1 st extension surface. Therefore, when the oil feed guide is disposed so that the filament travels from one side to the other side in the 1 st direction and the filament starts to contact the surface of the guide body at the peripheral edge portion of the discharge port, the portion of the filament near the end portion of the other side of the discharge port in the 1 st direction starts to contact the plane. This prevents a gap in which the oil agent is accumulated between the plane and the yarn or a gap which is very small even if a gap is formed. As a result, the finish can be uniformly applied to the yarn even when the viscosity of the finish is low.
The fuel filler guide according to claim 4 is the fuel filler guide according to claim 3, wherein, when viewed in the 2 nd direction, the one end portion of the discharge port in the 1 st direction and a portion of the guide body closer to the one end portion of the discharge port in the 1 st direction do not overlap with a 2 nd extension surface in which the 1 st extension surface is inclined by 10 ° in a direction approaching the one end portion of the discharge port in the 1 st direction with the other end portion of the discharge port in the 1 st direction as a center.
The oil feed guide may be disposed so that the plane is slightly inclined with respect to the traveling direction of the yarn. In the present invention, when viewed from the 2 nd direction, the end portion on the discharge port side in the 1 st direction and the portion of the guide body on the side closer to the end portion on the discharge port side in the 1 st direction do not overlap the 2 nd extension surface. Thus, even if the oil feeding guide is disposed so that the plane is inclined in a range of 10 ° or less with respect to the running direction of the thread, the thread starts to contact the plane at a portion near the other end of the discharge port in the 1 st direction, and therefore, a gap in which the oil agent is accumulated is not formed between the plane and the thread, or the gap is very small even if the gap is formed.
The fuel filler guide according to claim 5 is the fuel filler guide according to claim 3 or 4, wherein the contact surface has a curved surface that is connected to the other end of the plane in the 1 st direction and that is curved so as to protrude outward of the guide body.
In the present invention, the contact surface has a curved surface which is continuous with the other end portion of the plane in the 1 st direction and which is curved so as to project toward the outside of the guide main body, and therefore, the oil agent is not scraped off by the corner portion when the wire in contact with the contact surface is separated from the other end portion of the plane in the 1 st direction. This makes it possible to appropriately control the amount of finish applied to the yarn.
The spinning draft device according to claim 6 is a spinning draft device that drafts a yarn made of a plurality of filaments spun from a spinning device, and includes: an oil supply guide that supplies an oil agent to a yarn that travels from one side to the other side in a 1 st direction, the oil supply guide comprising: a guide body having a surface extending along the 1 st direction; and a discharge port formed in the surface of the guide body, the discharge port discharging an oil agent having a viscosity of 50cSt or less, the yarn coming into contact with the surface at a peripheral edge portion of the discharge port, the surface of the guide body having a contact surface located on the other side in the 1 st direction than the discharge port and with which the yarn is to be brought into contact, the contact surface being a curved surface curved so as to project toward an outer side of the guide body, an end portion of the discharge port on the one side in the 1 st direction and a portion of the guide body located on the one side in the 1 st direction than the end portion of the discharge port on the one side not overlapping a tangent line of the curved surface at a position of the end portion of the discharge port on the other side in the 1 st direction, as viewed from the 2 nd direction.
In contrast to the present invention, a case is considered in which the end portion on one side of the discharge port in the 1 st direction, or the portion of the guide body on one side of the end portion on one side of the discharge port in the 1 st direction, as viewed from the 2 nd direction, overlaps with the tangent line of the curved surface at the position of the end portion on the other side of the discharge port in the 1 st direction. In this case, when the fueling guide is disposed so that the wire is advanced from one side to the other side in the 1 st direction and the wire is brought into contact with the surface of the fueling guide at the peripheral edge portion of the discharge port, the portion of the wire near the end portion on the one side of the discharge port in the 1 st direction is brought into contact with the surface of the guide body. Thus, a gap can be formed between the curved surface and the wire. Further, the oil agent discharged from the discharge port is accumulated in the gap, and the oil agent accumulated in the gap is applied to the yarn. However, when the viscosity of the oil agent is low and the amount of oil agent discharged per unit time is small, there is a concern that: the oil agent does not stay in the gap for a long time and easily flows down, so that the amount of the oil agent in the gap is unstable, and the oil agent is unevenly adhered to the yarn (uneven adhesion).
In the present invention, when viewed from the 2 nd direction, the end portion on one side of the discharge port in the 1 st direction and the portion of the guide body on one side of the end portion on one side of the discharge port in the 1 st direction do not overlap with the tangent line of the curved surface at the position of the end portion on the other side of the discharge port in the 1 st direction. Therefore, when the oil feeding guide is disposed so that the wire is advanced from one side to the other side in the 1 st direction and the wire is brought into contact with the surface of the guide body at the peripheral edge portion of the discharge port, the portion of the wire near the end portion of the other side of the discharge port in the 1 st direction comes into contact with the curved surface. This prevents a gap in which the oil agent is accumulated between the curved surface and the yarn or a gap which is very small even if a gap is formed. As a result, even when the viscosity of the finish oil is low and the discharge amount of the finish oil per unit time is small, the finish oil can be uniformly applied to the yarn.
Further, in the present invention, since the contact surface is a curved surface, the wire in contact with the curved surface is separated from the curved surface by advancing in a tangential direction at a portion on the other side of the other end of the discharge port. Therefore, the oil agent is not scraped off by the corner when the wire is separated from the curved surface. This makes it possible to appropriately control the amount of finish applied to the yarn.
A spinning draft device according to claim 7 is the spinning draft device according to claim 6, wherein the oiling guide is arranged such that: an angle formed by the tangent line and a running direction of the yarn to be in contact with the surface is 10 ° or less as viewed in the 2 nd direction, and the end portion on the one side of the discharge port in the 1 st direction and a portion of the guide body on the one side of the discharge port in the 1 st direction are not overlapped with a straight line formed by inclining the tangent line by 10 ° in a direction approaching the end portion on the one side of the discharge port in the 1 st direction with the end portion on the other side of the discharge port in the 1 st direction as a center.
The oil supply guide may be disposed such that a tangent to a contact surface at the other end of the discharge port in the 1 st direction is slightly inclined with respect to the running direction of the yarn. In the present invention, when viewed from the 2 nd direction, the one end portion of the discharge port in the 1 st direction and the portion of the guide body on the one side of the one end portion of the discharge port in the 1 st direction do not overlap with a straight line in which the tangent line is inclined by 10 ° in a direction approaching the one end portion of the discharge port in the 1 st direction with the other end portion of the discharge port in the 1 st direction as a center. Thus, even if the oil supply guide is disposed so that the tangent line is inclined in a range of 10 ° or less with respect to the running direction of the yarn, the portion of the yarn near the other end of the discharge port in the 1 st direction starts to contact the curved surface, and the gap in which the oil agent is accumulated as described above is not formed or is very small even if the gap is formed.
A spinning and drawing device according to claim 8 draws a yarn made of a plurality of filaments spun from a spinning device, and includes: an oil supply guide that supplies an oil agent to a yarn that travels from one side to the other side in a 1 st direction, the oil supply guide comprising: a guide body having a surface extending along the 1 st direction; and a discharge port formed on the surface of the guide body, the discharge port discharging an oil agent having a viscosity of 50cSt or less, the yarn coming into contact with the surface at a peripheral edge of the discharge port, the surface of the guide body having a contact surface located on the other side of the discharge port in the 1 st direction and coming into contact with the yarn, the contact surface having a flat surface forming an end portion on the other side of the discharge port in the 1 st direction, the end portion on the one side of the discharge port in the 1 st direction and a portion of the guide body located on the one side of the end portion on the one side of the discharge port in the 1 st direction do not overlap with a 1 st extension surface extending the flat surface, as viewed from the 2 nd direction.
In contrast to the present invention, a case is considered in which the end portion on the side of the discharge port in the 1 st direction as viewed from the 2 nd direction or the portion of the guide body on the side of the end portion on the side of the discharge port in the 1 st direction overlaps the 1 st extension surface. In this case, when the fueling guide is disposed so that the wire is advanced from one side to the other side in the 1 st direction and the wire is brought into contact with the surface of the fueling guide at the peripheral edge portion of the discharge port, the portion of the wire near the end portion on the one side of the discharge port in the 1 st direction is brought into contact with the surface of the guide body. Thus, a gap is formed between the contact surface and the wire. Further, the oil agent discharged from the discharge port is accumulated in the gap, and the oil agent accumulated in the gap is applied to the yarn. However, when the viscosity of the oil agent is low and the amount of oil agent discharged per unit time is small, there is a concern that: the oil agent does not stay in the gap for a long time and easily flows down, and therefore, the amount of the oil agent in the gap is unstable, and unevenness in adhesion (uneven adhesion) of the oil agent occurs on the yarn.
In the present invention, when viewed from the 2 nd direction, the end portion on the discharge port side in the 1 st direction and the portion of the guide body on the side closer to the end portion on the discharge port side in the 1 st direction do not overlap the 1 st extension surface. Therefore, when the oil feeding guide is disposed so that the wire is advanced from one side to the other side in the 1 st direction and the wire is brought into contact with the surface of the guide body at the peripheral edge portion of the discharge port, the portion of the wire near the end portion of the other side of the discharge port in the 1 st direction is brought into contact with the plane. This prevents a gap in which the oil agent is accumulated between the plane and the yarn or a gap which is very small even if a gap is formed. As a result, even when the viscosity of the finish oil is low and the discharge amount of the finish oil per unit time is small, the finish oil can be uniformly applied to the yarn.
In the spun yarn haul-off device according to claim 9 or 8, the fueling guide is disposed so as to include: an angle formed by the tangent line and a running direction of the yarn to be in contact with the surface is 10 ° or less as viewed in the 2 nd direction, and the end portion on the one side of the discharge port in the 1 st direction and a portion of the guide body on the one side of the discharge port in the 1 st direction are not overlapped with the 2 nd extended surface in which the 1 st extended surface is inclined by 10 ° in a direction approaching the end portion on the one side of the discharge port in the 1 st direction with the end portion on the other side of the discharge port in the 1 st direction as a center.
The oil feed guide may be disposed so that the plane is slightly inclined with respect to the traveling direction of the yarn. In the present invention, when viewed from the 2 nd direction, the end portion on the discharge port side in the 1 st direction and the portion of the guide body on the side closer to the end portion on the discharge port side in the 1 st direction do not overlap the 2 nd extension surface. Therefore, even if the oil supply guide is disposed so that the plane is inclined in a range of 10 ° or less with respect to the running direction of the yarn, the yarn starts to contact the plane at a portion near the other end of the discharge port in the 1 st direction, and a gap in which the oil is accumulated is not formed between the plane and the yarn or the gap is very small even if the gap is formed.
The spun yarn haul-off device according to claim 10 is the spun yarn haul-off device according to claim 8 or 9, wherein the fueling guide has a curved surface which is connected to the other end of the plane in the 1 st direction and curved so as to be convex toward an outer side of the guide body.
In the present invention, the contact surface has a curved surface which is continuous with the other end of the plane in the 1 st direction and which is curved so as to project toward the outside of the guide main body, and therefore, the oil agent is not scraped off by the corner when the wire in contact with the contact surface is separated from the other end of the plane in the 1 st direction. This makes it possible to appropriately control the amount of finish applied to the yarn.
The spinning draft device according to claim 11 is the spinning draft device according to any one of claims 6 to 10, wherein the oil guide discharges the finish oil having a concentration of 85% or more from the discharge port.
The viscosity of the oil agent becomes low in both cases where the concentration of the oil agent is low and high. However, since the amount of oil to be applied required for the yarn is not changed, the amount of oil discharged from the discharge port per unit time is smaller when the concentration of the oil is high than when the concentration of the oil is low in order to apply a predetermined amount of oil to the yarn. Therefore, when the concentration of the oil agent is high, the amount of the oil agent accumulated in the gap is likely to vary. Therefore, when the concentration of the oil agent is 85% or more, it is significant that the end portion on the side of the discharge port in the 1 st direction and the portion of the guide main body on the side of the end portion on the side of the discharge port in the 1 st direction do not overlap the tangent line or the 1 st extension plane, so that a gap for accumulating the oil agent is not formed or the gap is made small between the contact surface (curved surface or flat surface) and the yarn.
Effects of the invention
According to the present invention, even when the viscosity of the finish is low, the finish can be uniformly applied to the yarn.

(oil supply guide)
As described above, the oil supply guide 11 applies the finish to the yarn Y composed of the plurality of filaments F spun from the spinning device 2. The oil supply guide 11 is formed of a ceramic material such as alumina or zirconia, and has a guide main body 20 as shown in fig. 2 and 3. The surface 21 of the front side of the guide body 20 extends in the up-down direction. Further, the yarn Y (a plurality of filaments F) conveyed from the cooling section 3 and traveling from the upper side to the lower side (from one side to the other side in the 1 st direction) is in contact with the surface 21.
The guide body 20 also has an oil passage 22. The oil flow path 22 is formed inside the oil supply guide 11 and extends in the front-rear direction. The tip of the finish flow path 22 constitutes a discharge port 25 formed in the surface 21, and finish is applied to the yarn Y (a plurality of filaments F) by discharging finish from the discharge port 25. In the present embodiment, the concentration of the oil agent discharged from the discharge port 25 is about 85%. Here, the concentration of the oil agent refers to the total concentration of the active ingredients including oil components other than water and additives. Fig. 4 shows the relationship between the concentration of the oil agent and the viscosity of the oil agent. As shown in fig. 4, in general, the greater the difference between the oil amount and the water amount, the smaller the viscosity of the oil agent. For example, when the concentration of a certain oil agent is about 85%, the viscosity is about 45cSt (50cSt or less). Further, for example, as described in japanese patent application laid-open No. 7-70819, in the case of applying an oil agent having a viscosity of more than 50cSt to a yarn, yarn breakage often occurs, and therefore, it is known that an oil agent having a viscosity of 50cSt or less is preferably used as the oil agent applied to the yarn Y.
Here, the surface 21 of the guide body 20 has: an upper curved surface 26 located above an upper end 25a (end on one side in the 1 st direction) of the discharge port 25; and a lower curved surface 27 (a "contact surface" or a "curved surface" in the present invention) located below a lower end 25b (the other end in the 1 st direction) of the discharge port 25. Both the curved surfaces 26, 27 are curved so as to protrude toward the outside of the guide body 20.
Further, when viewed in the left-right direction (cross section of fig. 3), the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 above the upper end 25a of the discharge port 25 do not overlap the tangent L1 of the lower curved surface 27 at the position of the lower end 25b of the discharge port 25. Further, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 do not overlap with a straight line L2 that is a 10 ° rotation of the tangent line L1 clockwise in fig. 3 (in a direction approaching the upper end 25a of the discharge port 25) about the lower end 25b of the discharge port 25, when viewed from the left-right direction.
Here, in the present embodiment, for example, the length K between the upper end 25a and the lower end 25b of the discharge port 25 is set to about 0.1mm in the direction orthogonal to the tangent line L1, whereby the upper end 25a and the lower end 25b of the discharge port 25 are brought into the positional relationship as described above.
The oil supply guide 11 is configured to: the tangent line L1 is substantially parallel to the running direction of the yarn Y (filament F) fed from the cooling unit 3 when viewed from the left-right direction.
Two wire guide members 23 are disposed on the surface 21 of the guide body 20. The two yarn guide members 23 are disposed on the surface 21 on the right side of the discharge port 25 and on the left side of the discharge port 25, respectively. That is, the two yarn guide members 23 are disposed on the front surface 21 so as to be positioned on both sides of the discharge port 25 in the left-right direction. The two yarn guide members 23 extend obliquely with respect to the vertical direction so as to approach the center portion of the discharge port 25 in the horizontal direction as they go downward from above. Thus, the distance between the two yarn guide members 23 in the left-right direction decreases from the top to the bottom (from one side to the other side in the 1 st direction). Further, the plurality of filaments F conveyed from the cooling portion 3 are guided by the two yarn guide members 23 in the direction approaching the center side in the left-right direction of the discharge port 25 while passing through the oil supply guide 11, and are gradually gathered and collected to form 1 yarn Y.
(Effect)
Here, unlike the present embodiment, a case of applying an oil agent to the yarn Y using an oil supply guide 11' as shown in fig. 5 is considered. The surface 21 'of the oil supply guide 11' has an upper curved surface 26 'above the upper end 25 a' of the discharge port 25 'and a lower curved surface 27' below the lower end 25b 'of the discharge port 25'. The curved surfaces 26 ', 27 ' are each curved in such a manner as to be convex toward the outside of the guide body 20 '. Further, when viewed from the left-right direction (the cross section of fig. 5), an upper portion 20a 'of the guide body 20' above the upper end 25a 'of the discharge port 25' overlaps a tangent L1 'of the lower curved surface 27' at the position of the lower end 25b 'of the discharge port 25'.
In this case, when the yarn Y fed from the cooling unit 3 is brought into contact with the surface 21 'at the peripheral edge portion of the discharge port 25', the yarn Y first comes into contact with the upper end 25a 'of the discharge port 25' of the upper curved surface 26 'or a portion above the upper end 25 a'. Then, the yarn Y comes into contact with the portion a of the lower curved surface 27 ' below the lower end 25b ' of the discharge port 25 ', and moves from the portion S ' below the portion a of the lower curved surface 27 ' in the direction of the tangent T ' at that position, thereby separating from the lower curved surface 27 '.
In this case, a gap C is formed between the region of the lower curved surface 27 'between the lower end 25 b' of the discharge port 25 'and the portion a and the yarn Y, and the oil discharged from the discharge port 25' is accumulated in the gap C. Further, the oil agent accumulated in the gap C is applied to the yarn Y. At this time, if the viscosity of the oil agent is low and the discharge amount of the oil agent discharged from the discharge port 25' per unit time is small, the oil agent does not stay in the clearance C for a long time and easily flows down. Therefore, the amount of the oil agent accumulated in the gap C is unstable, and the amount of the oil agent applied to the yarn Y is also unstable. As a result, the yarn Y was unevenly attached with the finish (uneven attachment). Here, the viscosity of the oil agent also becomes low when the concentration of the oil agent is low (for example, 30% or less). However, since the amount of oil to be applied to the yarn Y is not changed, when the concentration of the oil agent is as high as about 85%, the amount of oil agent discharged from the discharge port 25' per unit time is smaller than when the concentration of the oil agent is low. Therefore, when the concentration of the oil agent is high, the amount of the oil agent accumulated in the clearance C is more likely to become unstable than when the concentration of the oil agent is low.
In addition, in the fueling guide, when the upper end of the discharge port is located on the tangent line of the lower curved surface at the position of the lower end of the discharge port as viewed in the left-right direction, the above-described problem does not occur. However, with such an oil feed guide, due to slight errors during manufacturing, there is a high possibility that the positional relationship between a tangent line of the lower curved surface at the position of the lower end of the discharge port, and the upper end of the discharge port and the upper portion of the guide body above the upper end of the discharge port, as viewed in the left-right direction, will be the same as that of the oil feed guide 11'. Further, in this case, as in the case of using the oil supply guide 11', there is a possibility that uneven adhesion may occur on the yarn Y.
In contrast, in the present embodiment, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 do not overlap the tangent L1 of the lower curved surface 27 at the position of the lower end 25b of the discharge port 25 when viewed in the left-right direction. Therefore, when the yarn Y (filament F) fed from the cooling unit 3 is brought into contact with the surface 21 at the peripheral edge portion of the discharge port 25, the yarn Y is brought into contact with the lower curved surface 27 at a portion of the lower curved surface 27 in the vicinity of the lower end 25b of the discharge port 25, and is not brought into contact with the upper curved surface 26. This prevents a gap for accumulating the oil agent from being formed between the lower curved surface 27 and the yarn Y, or even if a gap is formed, the gap is very small. Therefore, the finish oil discharged from the discharge port 25 is directly applied, the amount of finish oil applied to the yarn Y is stable, and uneven adhesion to the yarn Y is less likely to occur.
The oil supply guide 11 may be disposed in a posture in which the tangent line L1 is slightly inclined with respect to the running direction of the yarn Y fed from the cooling unit 3. In contrast, in the present embodiment, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 do not overlap with a straight line L2 that is a 10 ° rotation of the tangent line L1 clockwise in fig. 3 (in a direction approaching the upper end 25a of the discharge port 25) about the lower end 25b of the discharge port 25, as viewed in the left-right direction. Accordingly, even when the oil supply guide 11 is disposed in a posture in which the tangent line L1 is inclined in a range of 10 ° or less with respect to the direction of travel of the yarn Y fed from the cooling unit 3, the yarn Y does not form a gap in which the oil agent is accumulated between the lower curved surface 27 and the yarn Y, or is minute even if a gap is formed, as in the above case. This makes it difficult to cause uneven adhesion to the yarn Y.
In the present embodiment, the yarn Y travels from the portion S of the lower curved surface 27 below the portion (the lower end 25b of the discharge port 25) that comes into contact with the lower curved surface 27 in the direction of the tangent T at that position, and thus is separated from the lower curved surface 27. Therefore, when the yarn Y is separated from the oil supply guide 11, the oil agent attached to the yarn Y is not scraped off by the corner portion. This makes it possible to appropriately control the amount of finish applied to the yarn Y.
[ examples ] A method for producing a compound
Next, examples of the present invention will be explained.
Fig. 6 (a) shows the measurement results of U% of the yarn after finish application when 3 kinds of finishes, G1, G2, and G3, are applied to the yarn Y using the oil feeding guide 11 ' in which the tangent line L1 ' of the lower curved surface 27 ' at the position of the upper portion 20a ' of the guide main body 20 ' and the lower end 25b ' of the discharge port 25 ' overlap when viewed from the left-right direction (comparative examples 1 to 3).
Fig. 6 (b) shows the measurement results of U% of the yarn after finish application when 3 kinds of finishes, i.e., finishes G1, G2, and G3, are applied to the yarn Y using the oil supply guide 11 in which the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 do not overlap the tangent L1 of the lower curved surface 27 at the position where the lower end 25b of the discharge port 25 is viewed from the left-right direction (examples 1 to 3).
Here, U% of the yarn shows the degree of variation in yarn diameter after the finish is applied. The diameter of the yarn varies depending on the amount of finish applied, and the smaller the unevenness in adhesion of finish to the yarn, the smaller the U%. The yarn used in the measurement was a polyester yarn. As shown in fig. 6 (c), oil G1 was 85% in concentration and 45cSt in viscosity. Finish G2 was a 90% strength, 38cSt viscosity finish. Finish G3 was 98% strength and 23cSt viscosity.
The measurement results of U% of comparative examples 1 to 3 shown in fig. 6 (a) are average values of the measurement results of U% when a plurality of oil supply guides 11 'are prepared and an oil agent is applied to the yarn using the oil supply guides 11'. The average value of the radii of curvature of the lower curved surfaces 27 'of the plurality of oil supply guides 11' used in the measurements of comparative examples 1 to 3 was 32.6 mm. The average value of the amount of displacement of the upper end 25a 'of the discharge port 25' of the oil supply guide 11 'to the front side in the front-rear direction with respect to the lower end 25 b' is 0.055 mm.
The measurement results of U% of examples 1 to 3 shown in fig. 6 (b) are average values of the measurement results of U% when a plurality of oil supply guides 11 are prepared and the oil is applied to the yarn using the oil supply guides 11. The average value of the radii of curvature of the lower curved surfaces 27 of the plurality of oil supply guides 11 used in the measurements of examples 1 to 3 was 32.7 mm. The average value of the amount of displacement of the upper end 25a of the discharge port 25 of the oil supply guide 11 toward the rear side in the front-rear direction with respect to the lower end 25b is 0.058 mm.
The ratio Q in fig. 6 (b) is a ratio of U% in each example to U% in a comparative example measured using the same oil agent as in the example. The smaller the value of the ratio Q, the greater the effect of improving the uneven adhesion of the oil agent. In any of examples 1 to 3, the value of the ratio Q was smaller than 1, and it was found that the oil agent had less uneven adhesion than in comparative examples 1 to 3.
The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made in the description of the technical means.
In the above-described embodiment, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 do not overlap the straight line L2 when viewed from the left-right direction, but the present invention is not limited thereto. The upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 may overlap the straight line L2, as long as they do not overlap the tangent line L1 when viewed from the left-right direction. In this case, the occurrence of uneven adhesion on the yarn Y can be prevented by disposing at least the oil feeding guide in a posture in which the tangent line L1 is substantially parallel to the running direction of the yarn F (yarn Y) fed from the cooling section 3.
In the above-described embodiment, the portion of the surface 21 of the guide body 20 located below the lower end 25b of the discharge port 25 is formed as the lower curved surface 27, but the present invention is not limited thereto. In one modification, as shown in fig. 7, in the oil feed guide 101, a surface 121 on the front side of the guide main body 120 has: a plane 126 located above the upper end 125a of the discharge port 125 and forming the upper end of the discharge port 125; a flat surface 127 (corresponding to a "flat surface" of the present invention) which is located below the lower end 125b of the discharge port 125 and forms the lower end of the discharge port 125; a plane 128 on the lower side than plane 127; and a flat surface 129 on the lower side than the flat surface 128. The plane 126 is inclined with respect to the vertical direction so as to be more upward and more rearward. The plane 127 is substantially parallel to the up-down direction. The flat surfaces 128 and 129 are inclined with respect to the vertical direction so as to be directed rearward as they are directed downward. The inclination angle of the plane 129 with respect to the vertical direction is larger than the inclination angle of the plane 128 with respect to the vertical direction. The flat surface 127 and the flat surface 128 are connected by a curved surface 130 that is curved so as to protrude toward the outside of the guide body 120. The flat surface 128 and the flat surface 129 are connected by a curved surface 131 that is curved so as to protrude toward the outside of the guide body 120. In the present modification, the surface formed by joining the flat surfaces 127 and 128 and the curved surface 130 corresponds to the "contact surface" of the present invention.
Further, in the present modification, the upper end 125a of the discharge port 125 and the upper portion 120a of the guide body 120 above the upper end 125a of the discharge port 125 do not overlap the 1 st extension surface H1 extending the plane 127 including the lower end 125b of the discharge port 125. The upper end 125a of the discharge port 125 and the upper portion 120a of the guide body 120 do not overlap the 2 nd elongated surface H2, which is inclined by 10 ° clockwise as viewed from the direction of fig. 7 about the lower end 125b of the discharge port 125, with the 1 st elongated surface H1.
In this case, when the filament Y is brought into contact with the surface 121 of the guide body 120 at the peripheral edge portion of the discharge port 125, the portion of the filament Y near the lower end 125b of the discharge port 125 is brought into contact with the flat surface 127 without being in contact with the flat surface 126. The thread Y exits from the surface 121 at a connecting portion between the plane 128 and the curved surface 131 after sequentially proceeding on the plane 127, the curved surface 130, and the plane 128. Further, even in this case, since a gap cannot be formed between the plane 127 and the yarn Y, the finish can be uniformly applied to the yarn Y.
In the present modification, since the plane 127 and the plane 128 are connected by the curved surface 130, the oil agent adhering to the yarn Y does not scrape off by the corner when the yarn Y travels from the plane 127 to the plane 128 (when it is separated from the lower end of the plane 127). Also, since the plane 128 and the plane 129 are connected by the curved face 131, when the filament Y exits from the surface 121, the filament Y exits in a tangential direction at a connecting portion of the curved face 131 to the plane 128. This prevents the oil agent adhering to the yarn Y from being scraped off by the corner when the yarn Y is separated from the lower end of the plane 128. Therefore, the amount of finish applied to the yarn Y can be appropriately controlled.
In the present modification, the portion of the surface 121 of the guide body 120 above the upper end 125a of the discharge port 125 is formed as the flat surface 126, but the portion of the surface 121 above the upper end 125a of the discharge port 125 may be formed as a curved surface as in the above-described embodiment. In the above-described embodiment, the portion of the front surface 21 above the upper end 25a of the discharge port 25 may be formed to be flat in the same manner as the above-described modified example.
In the above modification, plane 127 and plane 128 are connected by curved surface 130, and plane 128 and plane 129 are connected by curved surface 131, but the present invention is not limited to this. The plane 127 and the plane 128 may also be directly connected, the connection of the plane 127 and the plane 128 being formed as a corner. Likewise, the plane 128 and the plane 129 may be directly connected, and a connection portion of the plane 128 and the plane 129 is formed as a corner portion.
In the above embodiment, the concentration of the oil agent is about 85%, but the present invention is not limited thereto. The concentration of the finish may be further higher than 85%. Further, the viscosity of the oil agent is not limited to 50cSt or less by setting the concentration of the oil agent to 85% or more. For example, the viscosity of the oil agent may be set to 50cSt or less by setting the concentration of the oil agent to a low concentration of 30% or less. Even when the concentration of the oil agent is more than 30% and less than 85%, the viscosity of the oil agent may be 50cSt or less. Even in these cases, similarly to the above-described embodiment, when the oiling agent is applied to the yarn Y using the oil supply guide 11' shown in fig. 5, uneven adhesion is likely to occur on the yarn Y.
In the above-described embodiment, the stretching unit including the heat-insulating tank and the heating roller is disposed, but the present invention is not limited thereto. For example, the present invention can be applied also to a POY production facility which does not require heat stretching. In this case, for example, the concentration of the oil agent may be set to 15% or less and the viscosity of the oil agent may be set to 50cSt or less.
