Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing liquid from scattering, and more particularly to a device for preventing liquid from scattering out of a container when filling the container with liquid using a filling machine.

BACKGROUND OF THE INVENTION Conventionally, filling machines have been used to fill liquids such as lubricating oils, paints, drinking water, and liquid seasonings into suitable containers at relatively high speeds.

When using these filling machines, a container having an opening relatively larger than the diameter of the filling nozzle is used in consideration of the misalignment between the position of the filling nozzle and the opening of the container.

The container becomes full after a predetermined period of time after starting filling with liquid, but at that point the piston-type filling valve of the filling machine suddenly closes.

At this time, the pressure of the filled liquid causes the surface layer of the liquid inside the container to scatter to the outside through the opening of the container and is lost, and the outside of the container becomes dirty, making it necessary to clean the container.

The present invention aims to provide a device for preventing liquid from scattering during liquid filling.

The present invention will be explained with reference to the drawings.

As shown in Figures 2 and 3, the flat plate 1 has a hole 2 in its center that penetrates from the upper surface to the lower surface. As shown in Figure 3), the bottom surface is larger.

Furthermore, one or more holes 4 communicating with the through hole 2 are provided on the side surface of the flat plate 1.

This hole 4 is used to guide and collect a part of the liquid that has scattered from the container and entered directly opposite the scattering preventer, and if necessary, a conduit, a scattered liquid collecting container, etc. Can be connected.

The vertical cross-sectional shape of the through hole 2 is convex toward the side surface of the flat plate, so that the hollow portion of the flat plate is expanded.

4 to 6 show the embodiment.

By enlarging the hollow part of the flat plate in this way, it is possible to increase the receiving volume of the liquid that scatters from the container and prevent it from leaking to the outside. It exhibits cushioning properties when pressed and allows the anti-scattering plate to come into close contact with the opening of the container.

The material of the flat plate 1 is preferably an elastic body, such as natural rubber, synthetic rubber, home rubber, foamed resin, etc. Home rubber having closed cells and foamed resin are particularly preferred.

This material can be appropriately selected in consideration of the pressure applied when the opening of the container is pressed by the anti-scattering tool, the strength of the container, and the like.

The dimensions of the casing and flat plate must be at least large enough to completely cover the opening of the container.

Usually, the diameter is 1.5 to 3.0 times the diameter of the opening of the container, specifically 3 to 10 cm, and the thickness is about 1 to 7 m.

Next, to explain how to use the scattering prevention device 5 of the present invention, the scattering prevention device 5 is attached to the filling nozzle 6 of the filling machine as shown in FIG. The preventer 5 is attached so that the lower surface of the preventer 5 contacts the opening 8 of the container 7 from the time the filling is completed.

When the container 7 is sent to the liquid filling start point of the filling machine by a conveyor or other conveyance means, a container lifter (not shown) is activated to lift the container 1, so that the filling nozzle head enters the opening 8 of the container. Set to .

In this case, since the filling nozzle 6 is not always located at the center of the opening 8 of the container I, the diameter of the flat plate 1 constituting the scattering preventer 5 is made slightly larger than the diameter of the opening 8, and the container T
It is necessary to make the through-hole on the lower surface an appropriate size so that the through-hole on the lower surface does not protrude from the opening 8.

When filling of the liquid starts and reaches the filling end point, the piston valve 9 is suddenly closed, and a part of the filled liquid is scattered out of the container T from the opening 8 due to the pressure of the liquid at that time.

However, the splashed liquid hits the flat bottom surface of the scattering preventer 5 and drips back into the container, and the remaining part of the liquid hits the flat lower surface of the scattering preventer 5.
Most of the water reaches the internal space through the holes on the lower surface of the container, but most of it hits the inner wall surface and flows down to return inside the container, while the rest passes through the holes 4 and is led outside and collected.

Therefore, according to the present invention, there is no possibility that the liquid will scatter to the outside of the container when it is filled with liquid.

This eliminates the need to clean the outer surface of the container and prevents loss of liquid due to splashing.

In addition, the anti-scattering device of the present invention can be easily installed and removed, and the cam floor for piston valve operation
No other modifications are required.

The anti-scattering device of the present invention can be added to various automatic filling machines for liquids, and its range of use is extremely wide.
