DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn winding machine for winding a yarn or the like twisted by a multiple twisting machine, wherein oil is wound on the yarn when winding the yarn. The present invention relates to an oiling device of a yarn winding machine for attaching the yarn winding device.

[0002]

2. Description of the Related Art Conventionally, there has been known an oiling device for attaching oil to a yarn or the like which has been twisted by a multiple twisting machine when the yarn is wound by a yarn winding machine. The device is provided, for example, on the downstream side of the feed roller. Such oiling devices include:
As shown in FIG. 8, oil stored in an oiling tank 101 is attached to a yarn via an oiling roller 110 in some cases. The oil is supplied to the oiling tank 101 by, for example, supplying the oil stored in the main tank 103 to the sub-tank 102 and connecting the sub-tank 102 and the oiling tank 101 with a communication pipe 112. in this case,
The oil level of the oiling tank 101 and the oil level of the sub-tank 102 become the same height, and when the oil in the oiling tank 101 is consumed and the oil level falls, the float provided in the sub-tank 102 descends, and the oil tank 101
The oil is supplied from the main tank 103 into the sub tank 102 until the oil level of the oil tank rises to a predetermined height. As shown in FIG. 9, the oil stored in the main tank 103 is sucked up by a pump 115, supplied to the oiling tank 101 from a supply pipe 117, and
There is also a configuration in which the excess oil in the inside is overflowed from the discharge pipe 118 and discharged to the main tank 103 to circulate the oil.

[0003]

However, in the oiling apparatus constructed as shown in FIG. 8 described above, the oil in the oiling tank 101 is reduced because only the amount of oil adhering to the yarn is reduced. The amount is small, the main tank 103 to the sub tank 102 and the oiling tank 1
01 is supplied with only a small amount of oil. Therefore,
The oil in the oiling tank 101 is replaced only gradually, and the contamination of the oil in the oiling tank 101 proceeds at an early stage. On the other hand, in the case of a circulation type as shown in FIG. 9, the oil can be kept clean.
01, the amount of oil supplied to the oiling tank 101 pulsates and becomes unstable,
In particular, when the viscosity of the oil is high, the supply amount and the discharge amount of the oil to the oiling tank 101 are not balanced, and the oil may overflow from the oiling tank 101. Further, when finely adjusting the amount of oil supplied to the oiling tank 101, the rotation speed of the motor of the pump 115 must be finely adjusted, which makes the adjustment operation difficult.

[0004]

The present invention uses the following means to solve the above-mentioned problems in the oiling device of the yarn winding machine. That is, in the oiling device of the yarn winding machine, wherein the oil stored in the main tank is supplied to the oiling tank and the oil in the oiling tank adheres to the yarn, A sub-tank is provided above, and the oil stored in the main tank is supplied to the sub-tank by a pump, and the oil is supplied from the sub-tank to the oiling tank.
