The oil level fluctuates up and down depending on the amount, and the amount of oil on the surface of the coating roll varies. (B) When oil is directly supplied to the application tank by heating by a heater built in the oil application tank (supply tank), temperature fluctuation occurs,
The temperature cannot be maintained constant and the amount of oil on the surface of the coating roll changes.
(C) It is difficult to minutely replenish the amount of oil adhering to the filaments from the oil application roll, and there is a drawback that the amount of adhering oil used cannot be adjusted.

Oil tank (supply tank) for (2) direct, upper and lower rolls
In the method of supplying oil by rotating inside, (a) the amount of oil applied attached to the linear body cannot always be replenished, so the oil level decreases and the amount of oil on the upper and lower roll surfaces changes.
(B) There is a drawback that the temperature changes during replenishment. Therefore, the amount of adhesion to the filament cannot be adjusted.

The present invention has been made in view of the above points, and it is an object of the present invention to provide an oil application device and an oil application method for the surface of a linear body that makes it possible to make the amount of oil adhered to the surface of the linear body constant. It is intended.

[Means for Solving the Problem] The above object is to provide a backup tank adjacent to a supply tank, which pumps up the coating oil contained therein by a supply roll and supplies the supply oil to the supply tank via a knife edge and a gutter. Further, it is achieved by providing the supply tank with an overflow port for letting out the coating oil in the supply tank in excess of a predetermined amount and forming the overflow port in the oil coating device. Then, in order to apply the coating oil, a spare tank is provided adjacent to the supply tank, and the coating oil in this spare tank is pumped up by rotating the supply roll provided in the spare tank and supplied through the knife edge and the gutter. This is achieved by supplying the oil to the tank, and pumping the application oil in the supply tank, which has been supplied from the auxiliary tank and held at a predetermined amount, by the upper and lower rolls and applying it to the surface of the filament.

[Operation] Since the above-mentioned means is provided, it is possible to suppress the temperature change in the supply tank and make the height of the oil surface constant, and it is possible to make the oil amount on the upper and lower roll surfaces constant. become able to.

[Examples] Hereinafter, the present invention will be described based on illustrated examples. FIG. 1 shows an embodiment of the present invention. As shown in the figure, a supply tank 3 in which the coating oil 1 is stored and which is provided with a heating heater 2, and a rotatable tank provided in the supply tank 3 and connected to a variable speed motor 4 Above
Lower rolls 5 and 6 are provided, and the coating oil 1 in the supply tank 3 is applied to the surface of the linear body 7 by the lower rolls 5 and 6. In this embodiment, the oil coating device for the surface of the filament is used to draw up the coating oil 1 which is adjacent to the supply tank 3 and is accommodated therein by the supply roll 8, and the knife edge 9 and the gutter 10.
A spare tank 11 for supplying to the supply tank 3 via
In addition, the supply tank 3 is provided with an overflow port 12 for letting out the coating oil 1 that exceeds a predetermined amount in the supply tank 3. Then, in order to apply the coating oil 1 to the surface of the filamentous body, a spare tank 11 is provided adjacent to the supply tank 3, and the spare tank 11 is provided.
The coating oil 1 therein is pumped up by rotating a supply roll 8 provided in a spare tank 11, supplied to a supply tank 3 via a knife edge 9 and a gutter 10, and supplied from this spare tank 11 and held at a predetermined amount. The applied oil 1 in the supplied tank 3 was pumped up by the upper and lower rolls 5 and 6 to be applied on the surface of the filamentous body. By doing so, it becomes possible to suppress the temperature change in the supply tank 3 and to make the height of the oil surface constant, and to make the oil amount on the surfaces of the upper and lower rolls 5 and 6 constant. As a result, it is possible to obtain the oil applying device and the oil applying method for the surface of the filament, which makes it possible to make the amount of oil attached to the surface of the filament constant.

That is, the coating oil 1 in the spare tank 11 is pumped up by the supply roll 8 and supplied into the supply tank 3 using the knife edge 9 and the gutter 10. The upper and lower rolls 5 and 6 in the supply tank are rotated by the variable speed motor 4, and the coating oil 1 in the supply tank is pumped up and transferred to the upper roll 5. The transferred coating oil 1 adheres to the surface of the upper roll 5, adheres to the surface of the linear member 7 in contact with the upper roll 5, and supplies and coats the coating oil 1. The supply tank 3 has a built-in heating heater 2 so that the temperature of the coating oil can be kept constant, and the temperature is adjusted by a temperature controller. Further, by rotating the upper and lower rolls 5 and 6, it is possible to adjust the amount of oil adhered and applied to the linear body 7. The rotation can be arbitrarily changed by a separately provided voltage variable knob. The amount of oil in the supply tank 3 that is used by adhering to the filament 7 is supplied from the supply roll 8 in the spare tank 11 through the gutter 10, so that the oil level is always kept constant. When it is supplied more than necessary, the amount of oil in the supply tank is overflowed from the overflow port 12 to make the liquid level constant. By making the oil surface height constant, the amount of oil that adheres to the surfaces of the upper and lower rolls 5 and 6 can be made constant, and the oil that adheres to the filament 7 by the upper and lower rolls 5 and 6 The amount can also be kept constant. Striatum 7
After being coated with oil, the oil is passed through the felt 13 and wound up on a winding material. In the figure, 14 is a gear.

As described above, according to this embodiment, the following effects can be obtained.

(1) Since the coating oil adhering to the surface of the supply roll in the spare tank is constantly supplied to the supply tank via the knife edge, there is no shortage of oil supply, and oil shortage can be eliminated.

(2) Since the oil is constantly overflowed, the height of the oil surface is constant and the performance of oil application is constant. Since a fixed amount of oil adhered to the surface of the upper and lower rolls is supplied, a fixed amount of oil is constantly supplied.

(3) Since the amount of oil applied to the filament can be adjusted by changing the rotation of the upper and lower rolls, the quality guarantee of oil application to the filament can be maintained.

(4) By providing V-grooves and U-grooves on the surface of the upper and lower rolls, the contact with the filaments is increased and stable coating is secured.

(5) The temperature of the applied oil can be controlled by the heating heater and the temperature controller that can control the temperature, and the quality can be kept constant.

In this example, the upper roll was formed with a smooth surface,
The present invention is not limited to this, but the upper roll may be provided with a V-shaped groove as described above to improve oil adhesion to the filament.

Further, a slide mechanism for moving the supply tank up and down can be attached to facilitate oil supply to the supply tank.

In addition, an oil supply pipe is connected to the spare tank, and the liquid level sensor detects that the oil level has fallen from a separate tank using a constant supply pump to automatically supply oil. As a result, it is possible to prevent defective oil adhesion due to oil shortage. Human refueling can be avoided, eliminating human error.

[Advantages of the Invention] As described above, the present invention is provided with a backup tank adjacent to a supply tank, which pumps up the coating oil contained therein by a supply roll and supplies the applied oil to the supply tank via a knife edge and a gutter, and The supply tank was provided with an overflow port for letting out the coating oil in the supply tank in excess of a predetermined amount to form an oil coating device. Then, in order to apply the coating oil, a spare tank is provided adjacent to the supply tank, and the coating oil in this spare tank is pumped up by rotating the supply roll provided in the spare tank and supplied through the knife edge and the gutter. The coating oil in the supply tank, which was supplied to the tank and supplied from the spare tank and held at a predetermined amount, was pumped up by the upper and lower rolls and applied to the surface of the filament. By doing this, it is possible to suppress the temperature change in the supply tank and to make the height of the oil surface constant, and to make the oil amount on the upper and lower roll surfaces constant. It is possible to obtain an oil application device and an oil application method for the surface of a filament, which makes it possible to make the amount of oil attached to the surface of the filament constant.
