Abstract

(57) [Abstract] [Purpose] To provide a method and an apparatus for attaching a powder lubricant for removing the stickiness of the striatum. [Structure] In a method of depositing a powder lubricant in which a filament 1 is run through the inside of a powder lubricant 2, mechanical vibration of an appropriate cycle is continuously applied to the powder lubricant 2 by an appropriate vibrator 4. At the same time, mechanical stirring movement is performed by the stirring plate 6A or the high-pressure air jetted from the air jetting cylinder 7 at an appropriate period in the portion close to the portion of the linear lubricant 1 of the powder lubricant 2 that runs. And a device used for this method.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for depositing powder lubricant.

[0002]

2. Description of the Related Art For example, when winding a linear member 1 having a sticking property (tack property) such as a tape cord,
A powder lubricant 2 such as magnesium silicate or so-called talc is often adhered to the surface and then wound up. For this reason, the method shown in FIG. 3 is used.

That is, the vibration container 4 containing the powder lubricant 2 in the lubricant container 3 has an appropriate frequency, for example, about 50 hertz.
With this, the powder lubricant 2 inside the box is constantly shaken by this, and the powder lubricant 2 is allowed to pass through the linear body 1 to travel. Note that reference numeral 1A indicates a feeding device for the filamentous body 1, and 1B indicates a winding device. The reason why the powder lubricant 2 is vibrated is that the powder lubricant 2 is constantly moved and supplied from the surroundings to the position of the traveling line of the filament 1 and the powder lubricant 2 adheres well to the surface of the filament 1. To do so.

[0004]

However, with the passage of time, the powder lubricant 2 is compacted by the vibration of the vibrator 4 having a small amplitude, and an elongated tunnel-like cavity is formed in the running line of the filament 1. After all, there is a drawback that the powder lubricant 2 is hard to adhere to the surface of the linear body 1.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the means taken by the present invention is to apply a powder lubricant to a powder lubricant in a method for adhering a linear body through the inside of the powder lubricant. A mechanical stirring motion is continuously applied at an appropriate cycle, and mechanical stirring motion is applied at an appropriate cycle to a portion of the powder lubricant which is close to a portion where the linear body passes and travels. This is a method of attaching a powder lubricant.

Further, the means taken by the present invention is a mechanical system in which a lubricant storage box for storing a powder lubricant, a vibration exciter fixed to the lubricant storage box, and an operating body portion provided inside the lubricant storage box are provided. It is an apparatus for adhering a powder lubricant having a stirrer.

[0007]

[Function] The actuating portion of the mechanical agitator applies mechanical force to the powder lubricant in the lubricant storage box to loosen the crushed powder lubricant portion and move the positions to each other to run. It facilitates adhesion to the striatum.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus according to an embodiment of the present invention will be described with reference to FIG. Reference numerals 2, 3 and 4 are the same as in the case of FIG. 1 for explaining the prior art, and are a powder lubricant, a lubricant storage box, and a vibration exciter fixed thereto. In this invention, an appropriate fluid pressure cylinder 5 is attached to the lubricant container 3, and the stirring plate 6A is attached to the tip of the stirring rod 6 corresponding to the piston. The shape of the stirring plate 6A may be a flat plate (arbitrary planar shape) as shown in the drawing, or may be a columnar one having a spiral formed on its outer periphery. By supplying / discharging the pressure fluid to / from the fluid pressure cylinder 5, the powder lubricant 2 in the lubricant storage box 3 can be agitated to improve the tamped state.

FIG. 2 shows an apparatus according to another embodiment of the present invention,
In this case, an air ejection cylinder 7 is provided in the lubricant container 3, and high-pressure air ejected from a large number of holes formed in the outer peripheral wall pushes down the mass of the powder lubricant 2 in the surroundings and simultaneously It is possible to prevent a situation in which a long and narrow tunnel is formed in the shape of the filamentous body 1 by changing the parts of the lubricant and the positions of the parts. Reference numeral 72 is a compressed air tank, and 71 is an opening / closing valve.

The stirring rod 6 in these embodiments,
Although the air jetting cylinders 7 are both actuating body parts of the mechanical stirring device, rotating stirrers and the like are also very effective actuating body parts of the mechanical stirring device. . However, it is preferable that the mechanical agitation by such an agitation unit is applied every time period longer than the vibration period of the vibration exciter 4, for example, every 10 to 15 seconds. Although slightly away from the subject of the present invention, it is also important to remove moisture, which is one of the causes of solidification of the powder lubricant 2.
It is important for efficient operation of the method of the present invention that the outer box 8 is placed in an appropriate dehumidifying atmosphere to prevent the scattering of the powder lubricant 2.

[0011]

According to the present invention, the actuating portion of the mechanical stirrer applies a mechanical force to the powder lubricant in the lubricant storage box to loosen the crushed powder lubricant portion and This has the effect of facilitating the adhesion to the striatum that travels by changing the positions of each other.
