BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling device for removing bubbles mixed in a viscous substance such as silicone grease into a target container while removing bubbles.

[0002]

2. Description of the Related Art Viscous viscous materials such as silicone grease are sold in relatively large cans. At that time, if air is mixed in, the silicone grease may not be evenly injected into the entire target area, or the lubrication operation may be stopped halfway, when the automatic grease is injected into the target machine or equipment. , Causing work delays. 2. Description of the Related Art Conventionally, when filling silicone grease into a can, a technique of tapping with a tool such as a spatula to remove bubbles and filling the can in a desired amount has been adopted.

[0003]

As described above, the artificial filling operation using a spatula or the like has a basic problem that the defoaming efficiency is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the conventional circumstances, and has as its object the purpose of the present invention is to use a tool such as a spatula to perform an artificial filling and defoaming operation without performing a defoaming operation.

In order to achieve the above-mentioned object, the technical means taken in the method is that, in the method, a discharge section connected to a viscous material supply means is integrated with a predetermined interval around the discharge port. Of a viscous material discharged from the discharge port into a diffusion-preventing body for preventing the viscous material from being diffused in all directions, and a viscous material that is integrated with the lower end opening of the radiation-prevention body and is horizontally rotated to fill the viscous material with the filling container. The gist of the present invention is that the viscous material is discharged from the discharge unit into the filling container while simultaneously performing horizontal rotation and ascent of the discharge unit. Further, in synchronization with the discharge of the viscous material from the discharge unit,

A pressurizing body configured to press the viscous material in the bottom direction of the filling container by horizontally rotating the lower end opening of the anti-radiation body that prevents the viscous material from being diffused in all directions. The point is that Further, it is more effective to removably support the filling accommodating portion on a support base supported by means for rotating about a point horizontally displaced with respect to the rotation center of the discharge portion. The pressurizing body is laid on the lower end opening of the radiation preventing body, and the viscous material is filled on the bottom surface of one half and the other half of the half of the other half which is bounded by the rotation center of the rotating shaft when filling in the horizontal direction. For pressing in the direction of the bottom of the portion, each has a pressing inclined surface inclined in the opposite direction, and for stirring the viscous material when rotating in a horizontal direction each of the longitudinal side surfaces having the upper end of the pressing inclined surface as a lower end. It is also effective in the case of an elevation.

[0006]

According to the above technical means, the following effects are obtained.

Apply a pressing force in the direction. (Claims 2 and 4) The discharge section is positioned in a well-balanced manner over the entire filling space in the large filling accommodating section. (Claim 3) In addition to the effect of the first aspect, the discharge section is reliably raised in the vertical direction along the filling accommodating section (vertically-shaped container) without swinging in the left-right direction or the front-rear direction. (Claim 5) While stirring the discharged viscous material on the agitating upright surface of the pressurized body, the viscous material is forcibly pressed in the bottom direction by the pressing inclined surface to remove bubbles mixed therein. Fill the container for filling while foaming.

[0007]

According to the present invention, as described above, the viscous material is added to the filling container while defoaming the foam mixed without performing artificial filling and defoaming operations using a tool such as a spatula. A filling device for a viscous material that can be filled is provided. Moreover, claim 2,

Furthermore, in the fifth aspect, since the viscous material is formed into a pressurized body shape which is pressed toward the bottom of the filling container while being stirred, the defoaming efficiency can be further improved.
