Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a filling device for filling a bag-like container with a liquid. In contrast, this invention relates to a grommet holder that holds the inlet/outlet of the bag body, which is installed above the inclined surface of the table at a relatively high position, and is movable up and down as the liquid is being filled.

[Conventional technology]

A bag-shaped container is usually made by stacking two sheets of thin synthetic resin film and fusing the four sides together, and then forming a bag-shaped container with a cylindrical spout (called a grommet) in the corner of one side of the film. When filling liquid into a bag-like container made by fusing a holder with a concave portion (with which the tip of the holder that holds the pouring inlet engages), be sure to close the filling nozzle. The pouring port of the container is locked in the grommet holder provided at the bottom, and filling is started after specifying the position of the spouting port, but as the liquid filling progresses, all the weight of the filling liquid is poured through the film of the bag body. There is a risk of it getting stuck in the doorway and damaging the bag.
In this case, the bottom of the container is often placed on a table surface, and the weight of the filled liquid is supported by the tail.

[Problem that the invention attempts to solve]

When filling the liquid, the bag-shaped container is placed on the surface of the mounting table in a horizontally long state, and when the liquid is filled from the spout port fused to one side of the film at the corner of the container, the residual air in the container is removed from the bag. It may be difficult to remove the liquid from the spout port because it is obstructed by the film that makes up the liquid, or it may take a long time to remove the liquid from the spout. Also,
Even after the container is filled with a predetermined amount of liquid, air remaining in the bag remains in areas other than the spout opening and often becomes an obstacle when filling with inert sterile gas.

The present invention collects the air remaining in the bag-like container at a predetermined position of the container, near the pouring port, during filling of liquid and after filling a predetermined amount of liquid, thereby adjusting the amount of residual air and injecting inert and sterile gas. It is an object of the present invention to provide a filling device that allows easy filling and adjustment of the amount of filling.

[Means for solving problems]

The present invention has been made to improve the above-mentioned defects, and its main point is that in a filling machine of the type that fills a bag-like container with a pouring port by lying it on a table, the bottom of the container is filled with liquid. The surface of the mounting table is slightly inclined with respect to the horizontal plane, and a grommet holder that holds the pouring port of the bag is installed above the relatively high side of the inclined surface of the mounting table. A liquid filling device equipped with a grommet holder that moves up and down, characterized in that the grommet holder is moved up and down while holding the spouting port in connection with the filling operation.

〔Example〕

One embodiment of the present invention will now be described with reference to the drawings.

In Fig. 1, 1 is two thin synthetic resin films stacked on top of each other, their four sides fused together to form a bag shape, and a cylindrical spout 2 is fused to the corner of one side. In the grommet holder, a liquid filling nozzle (not shown) is installed facing downward directly above the spout port held in the grommet holder.

Reference numeral 5 denotes a table whose surface is inclined so that the side where the grommet holder 1 is located is higher and the side away from it is lower, and the container is held at the spouting port 2 by the grommet holder.
It is placed horizontally along the bottom surface of one side. In the figure, the liquid filling operation has progressed considerably and nearly the predetermined amount of liquid is contained in the container, but there remains a space between the liquid level and the container film, and a large amount of liquid remains in the container. Indicates that air is trapped inside the container.

However, since the surface of the container mounting table 5 is inclined, a certain angular relationship is maintained between the free surface of the filling liquid in the container and the table surface, that is, the bottom of the container, which naturally flows into the container. Influenced by the shape of the bag film surrounding the remaining air, the voids within the container are concentrated in the portion communicating with the spout, making it extremely easy to remove the air from inside the container.

The arrow displayed on the right side of the grommet holder 1 indicates that the holder 1 moves up or down in the direction of the arrow during and after filling the liquid. By concentrating the air on the side, it not only facilitates discharge from the spout but also makes it possible to adjust the amount of residual air.

Of course, it is necessary to adjust the lowering position of the holder to such an extent that there is no gap between the free surface of the filled liquid formed in the container by filling a predetermined amount of liquid and the outlet of the container, and to By arbitrarily adjusting the height of the holder, the amount of enclosed air can be adjusted freely.

Fig. 2 shows the same as Fig. 1, but after filling a predetermined amount of liquid, adjusting the vertical position of the holder to eliminate residual air in the bag container, and then fitting the cap 3 into the spout port 2. shows.

When filling the container with an inert sterile gas after filling the liquid, lower the holder to eliminate residual air in the container, switch the atmosphere to the inert gas side, raise the grommet holder, If the gas is inhaled onto the surface of the liquid filled in the container and the position of the holder is controlled so that an appropriate amount of inert gas remains in the container, then the cap 3 is attached to the spout port 2, making the work extremely easy. easily done.

In the above configuration, the rate or amount of downward movement of the grommet holder 1 may be linked to the liquid filling amount, but may be adjusted or finely adjusted separately. Furthermore, since the positional relationship (viewed in the vertical direction) between the table surface 5 and the grommet holder 1 is relative, the above-mentioned actions and effects also apply when the table surface is raised and lowered relative to the grommet holder position. It becomes something to play.

〔effect〕

As mentioned above, according to the present invention, the spouting port of the bag-like container is placed on the table at a high position, and the grommet holder that holds the spouting port is movable up and down, so that it is possible to As shown in Figure 2, the spout can be lowered to remove any remaining air in the container, and then the cap can be placed over the container. Therefore, the amount of air remaining in the container can be adjusted with a simple configuration.
