BACKGROUND OF THE INVENTION
The present invention relates to a roller oil supply device that is particularly effective when a water-containing oil agent is applied to a spun synthetic fiber, particularly polyamide fiber, by a single oil supply roller.
[0002]
[Prior art]
A roller oil supply device comprising an oil supply roller driven and rotated around a substantially horizontal roller shaft and an oil trough arranged immediately below the oil supply roller has long been used as a device for applying oil to a spun fiber yarn. Has been.
[0003]
In this roller oil supply device, the oil agent is stored in the rectangular tray portion of the oil agent trough, and a part of the lower portion of the oil supply roller is immersed in the stored oil agent, and the oil agent is applied to the roller surface as the oil supply roller rotates. The oil agent on the roller surface adheres, and the oil agent is applied to the yarn by the next contact with the running yarn. The amount of oil applied to the yarn is controlled by changing the rotation speed of the oiling roller. And since the fresh oil is always supplied into the rectangular trough of the oil trough and the excess oil is discharged, the oil in the rectangular dish is always slowly in a certain direction at a constant liquid level. Flowing.
[0004]
In the conventional apparatus, each of the oil supply port and the oil discharge port has one location, and the oil supply roller disposed on one end side of the rectangular dish portion extends from the oil supply port disposed on the other end side to the oil supply roller. The device structure was such that the oil flowed along the roller axis direction.
[0005]
By the way, recently, in order to improve the efficiency of the yarn production process, multiple yarns such as four or more yarns are melt-spun simultaneously, and each of the multiple yarns is cooled and supplied with oil by the same device, or further drawn. Thus, a yarn-making method of winding is often used.
[0006]
Therefore, a method has been adopted in which a multi-thread is fed in contact with the oil supply surface of the same oil supply roller in parallel.
[0007]
[Problems to be solved by the invention]
However, when a conventional roller oiling device is used to feed multiple yarns with the same oiling roller, there has been a problem that the adhering moisture and the adhering oil content greatly vary between the yarns. This problem is particularly noticeable when the oil is a hydrous oil.
[0008]
The level of moisture adhering to the yarn and the amount of oil adhering to it, especially in the case of polyamide fibers, greatly affects the wound package foam and fiber properties, etc. The problem was triggered.
[0009]
Therefore, the present invention solves the problems of the prior art as described above, even when supplying multiple yarns simultaneously by the same oil supply roller, or even when supplying a hydrous oil to polyamide fibers, The main purpose is to provide a roller oil supply device that can suppress variations in the amount of adhered moisture and adhered oil between yarns.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, a roller oil supply device according to the present invention is a roller oil supply device comprising an oil supply roller that is driven to rotate about a substantially horizontal roller shaft, and an oil trough disposed immediately below the oil supply roller. The oil trough is provided with a rectangular dish portion for storing an oil agent in which a part of the lower portion of the oil supply roller is immersed, and oil is applied to the rectangular dish portion from substantially the entire side parallel to the roller axial direction of the oil supply roller. is supplied, and oil from the left and right sides of each of the sides of its oil supply sides is discharged, the Taitojo the roller surface of the same oil supply roller is brought into contact in parallel, characterized that you refuel .
[0011]
When the oil supply to the rectangular dish and the oil discharge are configured as described above, the supplied fresh oil can be attached to any position on the immersed roller oil supply surface in the rectangular dish. . Therefore, even if multiple yarns are brought into contact with the same oil supply roller in parallel, the adhering moisture and the variation in the amount of adhering oil between the yarns are suppressed, and the level can be made substantially the same.
[0012]
That is, the oil agent stored and flowing in the rectangular plate part gradually changes in quality over time as it flows from the supply position flowing in the oil supply pipe to the discharge position of the discharge weir. It is extremely important for the oil agent adhering to the ink to have a certain quality in order to suppress the variation between the adhering moisture and the yarn content of the adhering oil. In view of this, the present invention employs an apparatus structure that allows the supplied fresh oil agent to adhere to the immersed roller oil supply surface at any position.
[0013]
On the other hand, when the oil agent flows along the roller axial direction as in the conventional device, the oil agent adhering to the roller surface gradually changes depending on the position in the roller axial direction. Variations in quality induced variations in the amount of moisture and oil adhering between the yarns.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be specifically described with reference to embodiments shown in the drawings.
[0015]
1 and 2 show an example of a roller oil supply device of the present invention. FIG. 1 is a plan view of the roller oil supply device, and FIG. 2 is a longitudinal sectional view taken along the line II-II ′ of FIG.
[0016]
Fresh oil is constantly supplied from the oil supply pipe 1 to the oil trough 7 of the roller oil supply device of the present invention. The supplied oil agent is supplied from substantially the entire side parallel to the roller axial direction of the oil supply roller 3 into the rectangular dish portion 6 for storing the oil agent in which a part of the lower portion of the oil supply roller 3 is immersed. is required. For this purpose, the oil agent from the oil agent supply pipe 1 is once supplied into the supply unit 8 separated from the rectangular dish 6 by the supply weir 2. In the supply weir 2, there is an oil agent circulation part 9 that leads to the rectangular dish part 6 over almost the entire surface, so that there is a gap over the almost entire surface between the lower end of the supply weir 2 and the bottom of the trough. Yes. This gap functions as the oil distribution part 9, that is, fresh oil is supplied from substantially the entire side parallel to the roller axis direction into the rectangular dish part under the supply weir 2. is there.
[0017]
Since the oil agent is supplied in this way, a fresh oil agent of almost the same quality is attached to the entire surface of the oil supply roller 3, and the problem that the quality of the attached oil agent varies in the roller axial direction can be solved.
[0018]
Furthermore, the oil discharged from the rectangular tray portion 6 of the oil trough is discharged from the discharge ports 5 and 5 'provided on the left side and the right side of the oil supply side. The discharge ports 5 and 5 'may be provided at a position close to the supply weir 2, but are preferably provided at a position away from the supply weir 2 as shown in FIG. The discharge ports 5, 5 'have a lower end height that is substantially the same as the oil surface height Q, thereby fulfilling the function of maintaining the oil surface height Q at a constant level and discharging excess oil. ing.
[0019]
By providing the discharge ports 5 and 5 'at the left and right positions (up and down positions in FIG. 1) in this way, the oil agent supplied over the entire surface of the oil supply roller surface is allowed to flow uniformly and be discharged. It is effective. Although it is ideal to provide a discharge port over the entire side facing the supply weir 2, there is a restriction that there is a yarn traveling position, so it is a reality to provide a discharge port at the position specified in the present invention. Is.
[0020]
The oil trough 7 of the device structure specified in the present invention can be made by integral molding of resin and / or by combination bonding of resin materials.
[0021]
In the above-described roller oil supply device of the present invention, fresh oil supplied from the oil supply pipe 1 is supplied from below the supply weir 2 to the rectangular dish 6 over substantially the entire side parallel to the roller axial direction. Therefore, when the roller surface is immersed in the oil agent, a homogeneous oil agent adheres to the entire surface in the roller axis direction, the adhered oil film surface is uniformly formed, and the multi-yarn Y is brought into contact with the same oil supply roller in parallel. Even so, the adhesion rate of the oil moisture is made uniform among the yarns. Note that the level of the amount of oil and moisture attached to the yarn may be adjusted by changing the rotation speed of the oil supply roller 3.
[0022]
[Examples and Comparative Examples]
Nylon 6 yarn is melt-spun by a usual method, cooled, supplied with a water-containing oil, and wound up at 700 m / min. Next, it is stretched 3.5 times by a conventional method to produce a 20-denier 13 filament Y-shaped nylon 6 stretched yarn.
[0023]
For supplying water-containing oil in the spinning process, the roller oil supply device of the present invention shown in FIGS. 1 and 2 was used, and oil was simultaneously supplied to four yarns running in parallel with the same oil supply roller. As shown in Table 1, the amount of oil and water adhering every four yarns was almost at the same level. On the other hand, when a conventional roller oil supply device in which the oil agent supply port is on the left side of the oil supply roller and the oil agent discharge port is on the right side of the oil supply roller and the oil agent flows along the roller axis direction is used, As shown in Table 1, the amount of adhesion varied greatly.
[0024]
Further, when the ratio of the 1.5 kg wound package that could not be wound due to the occurrence of yarn breakage in the drawing process was examined, it was as low as 7% when the oil was supplied by the roller oil supply device of the present invention. When the oil was supplied by a conventional roller oil supply device, it was extremely high at 45%.
[0025]
