JPS592133Y2 - Automatic spinning machine ring lubrication device - Google Patents

Description

[Detailed description of the invention] The present invention relates to the configuration of an automatic oil supply device for rings for spinning machines, which enables proper and smooth oil supply to the ring, securely fits the oil tank, and can be attached and detached with a single touch. This is what I did.

Furthermore, the oil tank that automatically refuels the ring is made larger, and this is removably fitted into the ring holder body, increasing the oil storage capacity of the oil tank and dramatically reducing the number of times the oil is replaced. The purpose is to prevent oil from escaping and leaching to prevent oil stains on the spun yarn, to measure the amount of leached oil evenly, and to facilitate and shorten the time required to replenish oil to the cartridge type oil supply tank. That is.

As shown in FIG. 1, a conventional ring holder using a cartridge-type oil tank has a recess 2 for fitting the cartridge-type oil tank in the main body 1 of the ring holder, and a bottom surface 8 of the recess 2 is sloped. There is one in which a cartridge type oil supply tank 11 is provided with a protrusion 13 and one oil guide hole 9 is provided in the recess 2, and the oil guide hole 9 is inserted into the protrusion 13 and fitted.

However, in the above configuration, when refueling the cartridge type oil tank 11, the oil guide hole 9 functions as an oil injection hole and an air exhaust port at the same time, so that oil escapes around the oil tank. Disadvantages include that it leaches out, causing oil stains, and that refueling work is difficult and time-consuming.

Furthermore, when refueling, oil oozes out along the protrusions, but since the exchange of air and oil is not performed smoothly, there is a drawback that the oil leaches out unevenly.

Furthermore, since the cartridge-type oil supply tank is simply fitted into a recess, it has the disadvantage that it can loosen and come off due to vibrations of the machine stand.

The present invention has been made to eliminate the various drawbacks mentioned above.

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, the ring holder main body 1 is provided with recesses 2 for fitting one or more cartridge type oil tanks 11,
One or more oil retaining substances 4 containing and retaining lubricating oil are inserted into the bottom 8 of the recess 2 to form an oil retaining layer, and one end of the oil supply thread 5 is inserted or press-fitted into a part of the oil retaining layer; The other end is led into the ring.

A wedge-shaped groove 6 extends over the entire circumference of the upper inner peripheral surface of the side wall of the recess 2.
An annular body 7 made of metal, resin, natural or synthetic rubber, etc. and having at least elasticity is fitted into the groove 6 to form a gripping part that prevents loosening or coming off. .

Incidentally, as the oil-retaining material 4, oil-retaining materials such as felt, sponge, and nonwoven fabric are suitable.

In addition, as shown in FIG. 3A and 3, the bottom surface 3 of the cartridge type oil supply tank 11 is provided with an oil guide hole 9 through which the lubricating oil 10 leaks out from inside the oil supply tank and an air hole 12 through which air enters instead of oil. One or more cartridge type oil supply tanks 11 are provided respectively.
As shown in FIG. 2, the ring holder is fitted into a recess 2 provided in the ring holder main body 1 so that the bottom surface having the hole of the oil tank 11 comes into contact with the oil retaining substance 4.

Note that the diameter of the oil guide hole is larger than the diameter of the air hole.

In addition, Fig. 3A shows an example in which holes are provided at three locations on the bottom of the fuel tank, and holes are provided in four locations on the bottom of the fuel tank, and the opening is located at the top of the recess 2 of the ring holder main body 1 on the side of the tank. A convex portion 14 is provided which engages with an annular body 7 provided on the holder.

Further, a concave portion may be provided instead of the convex portion 14.

Since the present invention has the above-mentioned configuration, when refueling the IJ fuel tank 11, oil is injected from the oil guide hole 9 and exhausted from the air hole 12, making the refueling work extremely difficult. It becomes easier.

Furthermore, when the cartridge type oil supply tank 11 is fitted into a holder as shown in FIG. Due to the capillary phenomenon of the oil retaining substance 4 that is in close contact with the bottom surface of the lubricant, it leaks out from the oil guide hole 9, and conversely, air enters through the air hole 12, and the exchange between lubricating oil and air becomes smooth, causing oil shortage or excess oil. This eliminates oil leakage and enables continuous, even automatic lubrication of the ring.

Furthermore, since the elastic annular body 7 is fitted into the wedge-shaped groove, it is possible to prevent the machine stand from lifting up or coming off due to vibration, and the oil tank can be attached and detached with one hand or with a single touch, which greatly reduces the hassle of replacement. This is a device that has many effects, such as reducing the amount of water used.
