[The problem to be solved by the invention]

Here, the fuel supply 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 or the like. In this case, the portion of the thread near the upper end of the ejection port starts to contact the contact surface, and a gap is formed between the thread and the second 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 thread. At this time, when the viscosity of the oil agent is low, the oil agent is likely to flow down from the gap, and the amount of the oil agent in the gap is likely to fluctuate with the passage of time. As a result, there is a concern that uneven adhesion (uneven adhesion) of the oil agent may occur on the thread.

An object of the present invention is to provide an oil supply guide that can uniformly apply an oiling agent to a thread even when the viscosity of the oiling agent is low, and a spinning traction device provided with the oil supply guide. [Technical means to solve the problem]

The lubrication guide of the first invention applies an lubricating agent to a thread composed of a plurality of filaments spun from a spinning device, and includes: a guide body having a surface extending in a first direction; and a discharge port, Formed on the surface of the guide body and used to discharge the oil; and two thread guide members are arranged on the both sides of the discharge port in a second direction orthogonal to the first direction The surface of the guide body extends so that the mutual interval in the second direction becomes narrower from one side in the first direction to the other side, and is used to feed a plurality of filaments toward the discharge The outlet is guided on the center side in the second direction, and the surface of the guide body has a contact surface that is located on the other side of the discharge port in the first direction and is used for contacting the thread, the contact surface It is a curved surface that is curved so as to protrude toward the outside of the guide body. When viewed from the second direction, the end of the discharge port on the one side in the first direction and the guide body The portion on the one side in the first direction that is closer to the one side than the end on the one side of the ejection port is not in contact with the curved surface at the position of the end on the other side of the ejection port in the first direction. The tangents overlap.

Unlike the present invention, it is considered that when viewed from the second direction, the end on the side of the discharge port in the first direction, or the end of the guide body on the side of the end on the side of the discharge port in the first direction The part is a case where it overlaps the tangent of the curved surface at the position of the end on the other side of the discharge port in the first direction. In this case, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the oil supply guide at the periphery of the discharge port, the thread is in The portion near the end on the side of the discharge port in the first direction starts to come into contact with the above-mentioned surface of the guide body. In this way, a gap is formed between the curved surface and the wire. Then, 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 thread. However, when the viscosity of the oil is low and the discharge amount of the oil per unit time is small, there is a concern that the oil cannot stay in the gap for a long time and easily flows down, so the amount of the oil in the gap is not It is stable and causes uneven adhesion (uneven adhesion) of the oil on the thread.

In the present invention, viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction. , Does not overlap with the tangent of the curved surface at the position of the end on the other side of the discharge port in the first direction. Therefore, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the guide body at the periphery of the discharge port, the thread moves in the first direction. The part near the end on the other side of the upper discharge port starts to come into contact with the curved surface. In this way, no gap is formed between the curved surface and the thread to allow the oil to accumulate, or even if the gap is formed, the gap is very small. As a result, even when the viscosity of the oil agent is low, the oil agent can be uniformly applied to the thread.

In addition, in the present invention, the contact surface is a curved surface. Therefore, the thread in contact with the curved surface travels in the tangential direction of the part on the other side than the end of the other side of the discharge port. Leave from the curved surface. Therefore, there is no possibility that the oil is scraped off the corner when the wire leaves from the curved surface. In this way, the amount of oil agent applied to the thread can be appropriately controlled.

The oil supply guide of the second invention is the oil supply guide of the first invention, as viewed from the second direction, the end of the discharge port on the one side in the first direction, and the guide body The portion on the one side of the discharge port in the first direction is closer to the one side than the end of the discharge port on the one side, and the tangent line is centered on the end on the other side of the discharge port in the first direction. The straight lines that are inclined by 10° near the end of the discharge port in the first direction do not overlap either.

The oil supply guide may be arranged so that the tangent line of the contact surface at the position of the end on the other side of the discharge port in the first direction is slightly inclined with respect to the traveling direction of the thread. In the present invention, viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction, It does not overlap with a straight line that is inclined by 10° in a direction approaching the end of the discharge port in the first direction with the tangent line on the other side of the discharge port in the first direction as the center. In this way, even if the oil supply guide is arranged so that the tangent line is inclined at a range of 10° or less with respect to the traveling direction of the thread, the thread is still in the first direction at the portion near the end on the other side of the ejection port and starts to contact with the curved surface. In contact, there is no gap between the curved surface and the thread that allows the oil to accumulate, or even if there is a gap, the gap is very small.

The oil supply guide of the third invention applies an oiling agent to a thread composed of a plurality of filaments spun from a spinning device, and includes: a guide body having a surface extending in a first direction; and a discharge port, Formed on the surface of the guide body and used to discharge the oil; and two thread guide members are arranged on the guide so as to be located on both sides of the discharge port in a second direction orthogonal to the first direction The surface of the main body extends so that the mutual interval in the second direction becomes narrower from one side of the first direction to the other side, and is used for directing a plurality of filaments toward the discharge port. The center side guide in the second direction, the surface of the guide body has: a contact surface that is located on the other side of the discharge port in the first direction and is used for making the thread contact, the contact surface has A plane forming the end of the other side of the discharge port in the first direction, viewed from the second direction, the end of the discharge port on the one side in the first direction, and the guide body The portion on the side of the side of the end of the discharge port in the first direction does not overlap with the first extended surface formed by extending the flat surface.

Unlike the present invention, it is considered that when viewed from the second direction, the end on the side of the discharge port in the first direction, or the part of the guide body on the side of the end on the side of the discharge port in the first direction , When overlapping with the first extended surface. In this case, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the oil supply guide at the periphery of the discharge port, the thread is in The portion near the end on the side of the discharge port in the first direction starts to come into contact with the above-mentioned surface of the guide body. In this way, a gap is formed between the above-mentioned plane and the thread. Then, 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 thread. However, when the viscosity of the oil is low and the discharge amount of the oil per unit time is small, there is a concern that the oil will not stay in the gap for a long time and will easily flow down, so the amount of the oil in the gap is not It is stable and causes uneven adhesion (uneven adhesion) of the oil on the thread.

In the present invention, viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction, Does not overlap with the first extended surface. Therefore, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the guide body at the periphery of the discharge port, the thread moves in the first direction. The part near the end on the other side of the upper discharge port starts to come into contact with the above-mentioned plane. In this way, no gap is formed between the above-mentioned flat surface and the thread to allow the oil to accumulate, or even if the gap is formed, the gap is very small. As a result, even when the viscosity of the oil agent is low, the oil agent can be uniformly applied to the thread.

The fuel supply guide of the fourth invention is, in the fuel supply guide of the third invention, viewed from the second direction, the end of the discharge port on the one side in the first direction, and the guide body The portion on the one side in the first direction than the end of the one side of the discharge port is on the other side of the discharge port in the first direction with the first extended surface The second extended surface does not overlap even when the end is the center and the second extended surface is inclined by 10° in the direction approaching the end on the one side of the discharge port in the first direction.

Sometimes the oil supply guide is arranged so that the above-mentioned plane is slightly inclined with respect to the traveling direction of the thread. In the present invention, viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction, Does not overlap with the second extended surface. In this way, even if the oil supply guide is arranged so that the above-mentioned plane is inclined within a range of 10° or less with respect to the traveling direction of the thread, the thread is still in the first direction at the part near the end of the discharge port on the other side. Since the above-mentioned plane is in contact, there is no gap between the plane and the thread for the oil to accumulate, or even if the gap is formed, the gap is very small.

According to the fuel supply guide of the fifth invention, in the fuel supply guide of the third or fourth invention, the contact surface has: connected to the end on the other side of the plane in the first direction and facing The curved surface of the guide body is curved in such a way that the outer side of the guide body is convex.

In the present invention, the contact surface has a curved surface that is connected to the end of the plane on the other side of the plane in the first direction and is curved so as to protrude toward the outside of the guide body. Therefore, there is no contact with the contact surface. When leaving the end of the thread on the other side of the plane in the first direction, the oil is scraped off from the corner. In this way, the amount of oil agent applied to the thread can be appropriately controlled.

The spinning drawing device of the sixth invention draws a yarn composed of a plurality of filaments spun from the spinning device, and is provided with an oil supply guide that faces from one side in the first direction to The thread running on the other side provides an oiling agent. The oil supply guide includes: a guide body having a surface extending along the first direction; and a discharge port formed on the surface of the guide body and used for discharging viscosity For the oil below 50cSt, the thread starts to come into contact with the surface at the peripheral edge of the discharge port, and the surface of the guide body has: in the first direction, it is located on the other side than the discharge port and is used to allow The wire contact surface, the contact surface is a curved surface that is curved so as to protrude toward the outside of the guide body, viewed from the second direction, the end of the discharge port on the one side in the first direction , And the part of the guide body that is closer to the one side than the end of the one side of the discharge port in the first direction is not connected to the end of the other side of the discharge port in the first direction The tangents of the above-mentioned curved surface overlap at the position.

Unlike the present invention, it is considered that when viewed from the second direction, the end on the side of the discharge port in the first direction, or the end of the guide body on the side of the end on the side of the discharge port in the first direction The part overlaps the tangent of the curved surface at the position of the end on the other side of the discharge port in the first direction. In this case, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the oil supply guide at the periphery of the discharge port, the thread is in The portion near the end on the side of the discharge port in the first direction starts to come into contact with the above-mentioned surface of the guide body. In this way, a gap is formed between the curved surface and the wire. Then, 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 thread. However, when the viscosity of the oil is low and the discharge amount of the oil per unit time is small, there is a concern that the oil will not stay in the gap for a long time and will easily flow down, so the amount of the oil in the gap is not It is stable and causes uneven adhesion (uneven adhesion) of the oil on the thread.

In the present invention, viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction, It does not overlap with the tangent of the curved surface at the position of the end on the other side of the discharge port in the first direction. Therefore, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the guide body at the periphery of the discharge port, the thread moves in the first direction. The part near the end on the other side of the upper discharge port starts to come into contact with the curved surface. In this way, a gap where the oil accumulates is not formed between the curved surface and the thread, or even if a gap is formed, the gap is very small. As a result, even when the viscosity of the oil agent is low and the discharge amount of the oil agent per unit time is small, the oil agent can be uniformly applied to the thread.

In addition, in the present invention, the contact surface is a curved surface. Therefore, the thread in contact with the curved surface travels in the tangential direction of the part on the other side than the end of the other side of the discharge port. Leave from the curved surface. Therefore, there is no possibility that the oil is scraped off the corner when the wire leaves from the curved surface. In this way, the amount of oil agent applied to the thread can be appropriately controlled.

In the spinning pulling device of the seventh invention, in the spinning pulling device of the sixth invention, the oil supply guide is arranged such that, when viewed from the second direction, the tangent is determined by the direction of travel of the thread that is about to be in contact with the surface The included angle is 10° or less, and the end on the one side of the discharge port in the first direction and the end of the guide body on the first direction are closer to the end on the one side of the discharge port in the first direction The part on the one side is the direction that the tangent line is centered on the end on the other side of the discharge port in the first direction toward the end on the one side of the discharge port in the first direction The straight lines do not overlap after being inclined by 10°.

The oil supply guide may be arranged so that the tangent line of the contact surface at the position of the end on the other side of the discharge port in the first direction is slightly inclined with respect to the traveling direction of the thread. In the present invention, when viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction , Does not overlap with a straight line that is inclined by 10° in a direction approaching the end of the discharge port in the first direction with the tangent line on the other side of the discharge port in the first direction as the center. In this way, even if the oil supply guide is arranged such that the tangent line is inclined within a range of 10° or less with respect to the traveling direction of the thread, the thread still starts to bend at the portion near the end on the other side of the discharge port in the first direction. Surface contact does not form a gap for the oil to accumulate as described above, or even if a gap is formed, the gap is very small.

The spinning pulling device of the eighth invention draws a yarn composed of a plurality of filaments spun from the spinning device, and includes: an oil supply guide that faces one side from the first direction The thread running toward the other side applies the oiling agent. The oil supply guide includes: a guide body having a surface extending along the first direction; and a discharge port formed on the surface of the guide body and used for discharging viscosity For the oil below 50cSt, the thread starts to come into contact with the surface at the peripheral edge of the discharge port, and the surface of the guide body has: located on the other side of the discharge port in the first direction and used for The contact surface for the thread to contact, the contact surface has a flat surface that forms the end of the discharge port in the first direction, and when viewed from the second direction, the discharge port in the first direction One end and the part of the guide body on the one side than the one end of the discharge port in the first direction does not overlap with the first extension surface formed by extending the plane .

Unlike the present invention, it is considered that when viewed from the second direction, the end on the side of the discharge port in the first direction, or the end of the guide body on the side of the end on the side of the discharge port in the first direction Part, overlap with the first extended surface. In this case, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the oil supply guide at the periphery of the discharge port, the thread is in The portion near the end on the side of the discharge port in the first direction starts to come into contact with the above-mentioned surface of the guide body. In this way, a gap is formed between the contact surface and the wire. Then, 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 thread. However, when the viscosity of the oil is low and the discharge amount of the oil per unit time is small, there is a concern that the oil will not stay in the gap for a long time and will easily flow down. Therefore, the amount of the oil in the gap It is unstable, and uneven adhesion of the oil agent (uneven adhesion) occurs on the thread.

In the present invention, when viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction are not Overlap with the first extended surface. Therefore, if the oil supply guide is arranged so that the thread travels from one side to the other side in the first direction, and the thread starts to come into contact with the surface of the guide body at the periphery of the discharge port, the thread moves in the first direction. The part near the end on the other side of the upper discharge port starts to come into contact with the above-mentioned plane. In this way, no gap is formed between the above-mentioned flat surface and the thread to allow the oil to accumulate, or even if the gap is formed, the gap is very small. As a result, even when the viscosity of the oil agent is low and the discharge amount of the oil agent per unit time is small, the oil agent can be uniformly applied to the thread.

The ninth invention of the spinning pulling device is the spinning pulling device of the eighth invention, wherein the oil supply guide is arranged such that, when viewed from the second direction, the tangent line is determined by the direction of travel of the thread that is about to be in contact with the surface. The included angle is 10° or less, and the end on the one side of the discharge port in the first direction and the end of the guide body on the first direction are closer to the end on the one side of the discharge port in the first direction The portion on the one side is the first extended surface that is centered on the end of the other side of the discharge port in the first direction toward the side closer to the discharge port in the first direction After the direction of the end portion is inclined by 10°, the second extended surface does not overlap either.

Sometimes the oil supply guide is arranged so that the above-mentioned plane is slightly inclined with respect to the traveling direction of the thread. In the present invention, when viewed from the second direction, the end on the side of the discharge port in the first direction and the portion of the guide body on the side of the end on the side of the discharge port in the first direction , Does not overlap with the second extended surface. In this way, even if the oil supply guide is arranged such that the above-mentioned plane is inclined within a range of 10° or less with respect to the traveling direction of the thread, the thread is still in the first direction at the part near the end on the other side of the discharge port. In flat contact, no gap is formed between the above-mentioned flat surface and the thread to allow the oil to accumulate, or even if a gap is formed, the gap is very small.

In the spinning pulling device of the tenth invention, in the spinning pulling device of the eighth or ninth invention, the fuel supply guide has: connected to the end on the other side of the plane in the first direction and A curved surface that is curved so as to protrude toward the outside of the guide body.

In the present invention, the contact surface has a curved surface that is connected to the end portion on the other side of the plane in the first direction and is curved to protrude toward the outside of the guide body. Therefore, it does not appear as a contact surface. When the touching thread leaves the end on the other side of the plane in the first direction, the oil is scraped off from the corner. In this way, the amount of oil agent applied to the thread can be appropriately controlled.

The eleventh aspect of the spinning traction device is the spinning traction device of any one of the sixth to tenth inventions, wherein the fuel supply guide discharges an oil agent having a concentration of 85% or more from the discharge port.

In either the case where the concentration of the oil agent is low and the case where the concentration of the oil agent is high, the viscosity of the oil agent becomes low. However, because the amount of oil required for the thread does not change, when the concentration of the oil is high, compared with the case where the concentration of the oil is low, in order to impart a predetermined amount of oil to the thread, the output is from the discharge port per unit time. The discharge amount of the discharged oil is small. Therefore, when the concentration of the oil agent is high, the amount of the oil agent accumulated in the gap is likely to fluctuate. Therefore, when the concentration of the oil agent is 85% or more, the end on the side of the discharge port in the first direction and the end of the guide body in the first direction are larger than the end on the side of the discharge port. The part on one side is set so as not to overlap with the tangent line or the first extended surface, so that there is no gap between the contact surface (curved surface or flat surface) and the thread that allows the oil to accumulate, or the gap is made small ,has great significance. [Effects of the invention]

Figure 4 shows the relationship between the concentration of the oil agent and the viscosity of the oil agent. As shown in Fig. 4, in the oil agent, generally, the greater the difference between the oil content and the water content, the lower the viscosity of the oil agent. For example, in a certain oil agent, when the concentration is about 85%, the viscosity is about 45 cSt (50 cSt or less). In addition, for example, as described in Japanese Patent Application Laid-Open No. 7-70819, when an oil with a viscosity of more than 50 cSt is applied to the yarn, wire breakage occurs in many cases. Therefore, it is used as an oil for the yarn Y. It is known that it is preferable to use an oil agent with a viscosity of 50 cSt or less.

Here, the surface 21 of the guide body 20 has an upper curved surface 26 that is higher than the upper end 25a of the discharge port 25 (one end in the first direction); and a lower end 25b (the first end) of the discharge port 25. The end on the other side in the direction 1) is further below the lower curved surface 27 ("contact surface" and "curved surface" in the present invention). The curved surfaces 26 and 27 are both curved in a manner protruding toward the outside of the guide body 20.

And when viewed from the left-right direction (the 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 are not in contact with the lower end 25b of the discharge port 25. The tangent line L1 of the lower curved surface 27 at the position overlaps. In addition, when viewed from the left and right direction, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 are aligned with the tangent line L1 centered on the lower end 25b of the discharge port 25 in the clockwise direction of FIG. 3 (close to the discharge port 25). The straight line L2 rotated by 10° in the direction of the upper end 25a does not overlap either.

Here, in the present embodiment, for example, in the direction orthogonal to the tangent line L1, by making the length K between the upper end 25a and the lower end 25b of the discharge port 25 approximately 0.1 mm, the upper end 25a of the discharge port 25 It is formed in the positional relationship as described above with the lower end 25b.

In addition, the oil supply guide 11 is arranged such that when viewed from the left-right direction, the tangent line L1 is substantially parallel to the traveling direction of the thread Y (filament F) fed from the cooling unit 3.

In addition, two thread guide members 23 are arranged on the surface 21 of the guide body 20. The two thread guide members 23 are respectively arranged on a portion of the surface 21 on the right side of the discharge port 25 and a portion on the left side of the discharge port 25. That is, the two thread guide members 23 are arranged on the surface 21 so as to be located on both sides of the discharge port 25 in the left-right direction. In addition, the two thread guide members 23 extend obliquely with respect to the up-down direction so as to approach the center portion in the left-right direction of the discharge port 25 as they go from the top to the bottom. Therefore, the more from above to downward (from one side to the other in the first direction), the distance between the two thread guide members 23 in the left-right direction becomes smaller. In addition, the plurality of filaments F fed from the cooling section 3 are guided toward the center of the discharge port 25 by the two yarn guide members 23 while passing through the oil supply guide 11, and are gradually bundled. And gather to form a silk thread Y.

(Effect) 　　 Here, unlike the present embodiment, a case where the oil supply guide 11' as shown in Fig. 5 is used to apply an oil to the thread Y is considered. The surface 21' of the oil supply guide 11' has an upper curved surface 26' above the upper end 25a' 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' and 27' are both curved in a manner of protruding toward the outside of the guide body 20'. And, viewed from the left-right direction (the cross section of FIG. 5), the upper portion 20a' of the guide body 20' which is higher than the upper end 25a' of the discharge port 25' is at a position with the lower end 25b' of the discharge port 25' The tangent L1' of the lower curved surface 27' overlaps.

In this case, when the thread Y fed from the cooling section 3 starts to contact the surface 21' at the peripheral edge of the discharge port 25', the thread Y first contacts the upper end 25a of the discharge port 25' of the upper curved surface 26' 'Or the upper part of the upper end 25a' is in contact with each other. Then, the thread Y comes into contact with the portion A of the lower curved surface 27' that is lower than the lower end 25b' of the discharge port 25', and from the portion S'that is lower than the portion A of the lower curved surface 27' It travels in the direction of the tangent line T'at this position, thereby leaving from the lower curved surface 27'.

In this case, a gap C is formed between the area between the lower end 25b' of the discharge port 25' and the portion A of the lower curved surface 27' and the thread Y, and the oil discharged from the discharge port 25' accumulates in the gap. C. Then, the oil agent accumulated in the gap C is applied to the thread Y. At this time, if the viscosity of the oil is low and the discharge amount of the oil discharged from the discharge port 25' per unit time is small, the oil does not stay in the gap C for a long time and easily flows down. Therefore, the amount of oil agent accumulated in the gap C is unstable, and the amount of oil agent applied to the thread Y is also unstable. As a result, uneven adhesion of the oil agent (uneven adhesion) occurs on the thread Y. Here, when the concentration of the oil agent is low (for example, 30% or less), the viscosity of the oil agent also becomes low. However, because the amount of oil required to cope with the thread Y does not change, when the concentration of the oil is as high as about 85%, the oil is discharged from the discharge port 25' per unit time compared to the case where the concentration of the oil is low. The discharge amount of the medicine decreases. Therefore, when the concentration of the oil agent is high, the amount of the oil agent accumulated in the gap C is more likely to become unstable than when the concentration of the oil agent is low.

In addition, in the oil supply 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, the above-mentioned problem does not occur when viewed from the left-right direction. However, with regard to such an oil supply guide, due to a slight error during manufacture, when viewed from the left and right, the tangent to the lower curved surface at the position of the lower end of the discharge port is compared with the upper end of the discharge port and the guide body. There is a high possibility that the positional relationship between the upper part of the upper end of the upper part of the oil supply guide 11' becomes the same. Furthermore, in this case, as in the case of using the oil supply guide 11', there is a concern that uneven adhesion of the thread Y may occur.

In contrast, in the present embodiment, when viewed from the left and right direction, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 are not in contact with the lower curved surface 27 at the position of the lower end 25b of the discharge port 25. The tangent line L1 overlaps. Therefore, when the thread Y (filament F) fed from the cooling section 3 starts to contact the surface 21 at the peripheral edge of the discharge port 25, the thread Y starts at the portion near the lower end 25b of the discharge port 25 of the lower curved surface 27 It is in contact with the lower curved surface 27 but not with the upper curved surface 26. In this way, no gap is formed between the lower curved surface 27 and the thread Y to allow the oil to accumulate, or even if a gap is formed, the gap is very small. Therefore, the oil agent discharged from the discharge port 25 is directly applied, and the amount of the oil agent applied to the thread Y is stable, and it is difficult to cause uneven adhesion on the thread Y.

In addition, the oil supply guide 11 may be arranged in a posture in which the tangent line L1 is slightly inclined with respect to the traveling direction of the thread Y conveyed from the cooling unit 3. On the other hand, in this embodiment, viewed from the left and right direction, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 are aligned with the tangent line L1 centered on the lower end 25b of the discharge port 25 in FIG. 3 The straight line L2 rotated by 10° in the clockwise direction (the direction approaching the upper end 25a of the discharge port 25) does not overlap either. In this way, even when the oil supply guide 11 is arranged in a posture in which the tangent line L1 is inclined within a range of 10° or less with respect to the traveling direction of the thread Y conveyed from the cooling unit 3, it is the same as in the above case and will not be lowered. A gap is formed between the side curved surface 27 and the thread Y to allow the oil to accumulate, or even if a gap is formed, the gap is very small. As a result, it is difficult to cause uneven adhesion on the thread Y.

In addition, in the present embodiment, the thread Y travels from the portion S on the lower side of the curved surface 27 to the lower side than the portion (lower end 25b of the discharge port 25) where it starts to come into contact in the direction of the tangent T at that position, thereby It is separated from the lower curved surface 27. Therefore, when the wire Y is separated from the oil supply guide 11, the oil adhering to the wire Y will not be scraped off at the corners. Thereby, the amount of the oil agent applied to the thread Y can be appropriately controlled. [Example]

Next, an embodiment of the present invention will be described.

Figure 6 (a) shows the use of an oil supply guide in which the upper portion 20a' of the guide body 20' and the lower end 25b' of the discharge port 25' overlap the tangent L1' of the lower curved surface 27' when viewed from the left and right direction Item 11', measurement results of U% of the thread after the oil agent application when the three types of oil agents G1, G2, and G3 were applied to the thread Y (Comparative Examples 1 to 3).

6(b) shows that the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 do not overlap with the tangent L1 of the lower curved surface 27 at the position of the lower end 25b of the discharge port 25 when viewed from the left and right direction. The measurement results of U% of the thread after the oiling agent application when the oiling agent G1, G2, and G3 were applied to the thread Y with the oil supply guide 11 (Examples 1 to 3).

Here, the U% of the thread represents the degree of deviation of the thread diameter after the application of the oil agent. The diameter of the thread changes according to the amount of the oil agent applied, and the smaller the unevenness of the adhesion of the oil agent to the thread, the smaller the U%. In addition, the thread used in the measurement was a polyester thread. And, as shown in FIG. 6(c), the oil agent G1 is an oil agent having a concentration of 85% and a viscosity of 45 cSt. The oil agent G2 is an oil agent with a concentration of 90% and a viscosity of 38 cSt. The oil agent G3 is an oil agent with a concentration of 98% and a viscosity of 23 cSt.

In addition, the measurement results of U% of Comparative Examples 1 to 3 shown in Fig. 6(a) were obtained when a plurality of oil supply guides 11' were produced, and these oil supply guides 11' were used to apply oil to the thread. The average of U% measurement results. In addition, the average value of the curvature radius of the lower curved surface 27' of the plurality of fuel supply guides 11' used in the measurement of Comparative Examples 1 to 3 was 32.6 mm. In addition, the average value of the amount of displacement of the upper end 25a' of the discharge port 25' of the fuel supply guide 11' to the front side of the lower end 25b' in the front-rear direction is 0.055 mm.

In addition, the U% measurement results of Examples 1 to 3 shown in FIG. 6(b) are U% when a plurality of oil supply guides 11 are produced, and these oil supply guides 11 are used to apply oil to the thread. The average of the measurement results. In addition, the average value of the radius of curvature of the lower curved surface 27 of the plurality of fuel supply guides 11 used in the measurement of Examples 1 to 3 was 32.7 mm. In addition, the average value of the offset amount of the upper end 25a of the discharge port 25 of the fuel supply guide 11 toward the rear side in the front-rear direction with respect to the lower end 25b is 0.058 mm.

In addition, the ratio Q in FIG. 6(b) is the ratio of U% in each example to U% in the comparative example measured using the same oil agent as 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 is all smaller than 1, and it can be seen that the adhesion unevenness of the oil agent is smaller than that of 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-mentioned embodiments, and various modifications can be made within the scope of the patent application.

In the above-mentioned embodiment, when viewed from the left-right direction, 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, but it is not limited to this. When viewed from the left-right direction, the upper end 25a of the discharge port 25 and the upper portion 20a of the guide body 20 may not overlap the tangent line L1, and may overlap the straight line L2. In this case, as long as the oil supply guide is arranged in a posture that at least the tangent line L1 is substantially parallel to the traveling direction of the filament F (thread Y) conveyed from the cooling section 3, it is possible to prevent uneven adhesion on the thread Y. .

In addition, in the above-described embodiment, the portion of the surface 21 of the guide body 20 that is located below the lower end 25b of the discharge port 25 is formed as the lower curved surface 27, but it is not limited to this. In a modified example, as shown in FIG. 7, in the oil supply guide 101, the front surface 121 of the guide body 120 has a flat surface 126, which is located above the upper end 125a of the discharge port 125 and forms a discharge port 125 The upper end of the plane 127 (equivalent to the "plane" of the present invention), which is located on the lower side than the lower end 125b of the discharge port 125 and forms the lower end of the discharge port 125; a plane 128 that is lower than the plane 127; and a plane 128 that is lower than the plane 128 is further down the plane 129. The flat surface 126 is inclined with respect to the up-down direction so that the more it faces upward, the more it faces backward. The plane 127 is substantially parallel to the vertical direction. The flat surfaces 128 and 129 are inclined with respect to the up-down direction so that the more they face downward, the more they face rearward. In addition, the inclination angle of the plane 129 with respect to the vertical direction is greater than the inclination angle of the plane 128 with respect to the vertical direction. In addition, the flat surface 127 and the flat surface 128 are connected by a curved surface 130 that is curved to protrude toward the outside of the guide body 120. In addition, 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 addition, in this modification, the flat surfaces 127 and 128 and the curved surface 130 together correspond to the "contact surface" of the present invention.

Furthermore, in this 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 are not extended from the plane 127 that includes the lower end 125b of the discharge port 125. The resulting first extended surface H1 overlaps. In addition, the upper end 125a of the discharge port 125 and the upper portion 120a of the guide body 120 are inclined by 10° in the clockwise direction as viewed from the direction of FIG. 7 with the first extension surface H1 centered on the lower end 125b of the discharge port 125. The second extended surface H2 does not overlap either.

In this case, when the thread Y is about to come into contact with the surface 121 of the guide body 120 at the periphery of the discharge port 125, the portion of the thread Y near the lower end 125b of the discharge port 125 starts to contact the flat surface 127 instead of the flat surface. 126 contacts. In addition, after the thread Y travels in the plane 127, the curved surface 130, and the plane 128 in sequence, it leaves the surface 121 at the connecting portion of the plane 128 and the curved surface 131. Moreover, even in this case, a gap is not formed between the flat surface 127 and the thread Y, so the thread Y can be uniformly applied with oil.

In addition, in this modification, the plane 127 and the plane 128 are connected by the curved surface 130. Therefore, there is no occurrence of the wire Y being attached to the wire Y when it travels from the plane 127 to the plane 128 (when leaving from the lower end of the plane 127). When the oil is scraped off the corner. In addition, since the flat surface 128 and the flat surface 129 are connected by the curved surface 131, when the thread Y leaves the surface 121, the thread Y leaves in the tangential direction of the connecting portion of the curved surface 131 connected to the flat surface 128. Therefore, when the thread Y is separated from the lower end of the flat surface 128, the oil agent attached to the thread Y will not be scraped off at the corners. Therefore, the amount of oil agent applied to the thread Y can be appropriately controlled.

In addition, in this modification, the part of the surface 121 of the guide body 120 above the upper end 125a of the discharge port 125 is formed as a flat surface 126. However, the surface 121 may be formed more than the upper end 125a of the discharge port 125. The upper part is formed as a curved surface similarly to the above-mentioned embodiment. Furthermore, in the above-mentioned embodiment, the part of the surface 21 above the upper end 25a of the discharge port 25 may be formed into a flat surface similarly to the above-mentioned modification.

In addition, in the above modification, the flat surface 127 and the flat surface 128 are connected by the curved surface 130 and the flat surface 128 and the flat surface 129 are connected by the curved surface 131, but it is not limited to this. The plane 127 and the plane 128 may also be directly connected, and the connecting portion of the plane 127 and the plane 128 is formed as a corner. Similarly, the plane 128 and the plane 129 can also be directly connected, and the connecting portion of the plane 128 and the plane 129 is formed as a corner.

In addition, in the above-mentioned embodiment, the concentration of the oil agent is about 85%, but it is not limited to this. The concentration of oil can also be higher than 85%. In addition, it is not limited to make the viscosity of the oil agent 50 cSt or less by making the concentration of the oil agent 85% or more. For example, by making the concentration of the oil agent a low concentration of 30% or less, the viscosity of the oil agent may be 50 cSt or less. In addition, even in the case where the concentration of the oil agent is greater than 30% and less than 85%, as long as the viscosity of the oil agent is 50 cSt or less. Even in these cases, as in the above-mentioned embodiment, when the oil supply guide 11' shown in FIG.

In the above-mentioned embodiment, the stretching part provided with the heat preservation box and the heating roller is arrange|positioned, but it is not limited to this. For example, the present invention can also be applied to POY production equipment that does not require heating and stretching. In this case, for example, the concentration of the oil agent may be 15% or less and the viscosity of the oil agent may be 50 cSt or less.
