Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the use of a flexible container bag for mass transport or storage of powdered or granular products such as minerals, resins, and grains. The present invention relates to an apparatus for filling a flexible container bag, wherein the filling is performed mechanically.

[0002]

2. Description of the Related Art The above flexible container bag is
Usually, a bag main body having a large sectional area in plan view and having a sufficient capacity to store the above-mentioned filling material, and a bag projecting upward from the upper surface of the bag main body and having an axial center extending substantially vertically. A cylindrical inlet for communicating between the inside and the outside of the main body, and a cylindrical outlet for projecting downward from the lower surface of the bag body and communicating between the inside and the outside of the bag main body,
The filler can be injected into the bag body through the cylindrical inlet, and the filler stored in the bag body can be discharged to the outside through the cylindrical outlet.

[0003] When the packing is transported using the above-mentioned flexible container bag, first, prior to this use, each flexible container bag is made into a flat shape in the vertical direction as a whole by hand, and a large number of bags are formed. Of flexible container bags are stacked on a support.

Next, the uppermost flexible container bag of the group of flexible container bags stacked as described above is picked up by hand,
In addition, the cylindrical inlet of the flexible container bag is in an upright posture, and the cylindrical inlet is externally fitted to a discharge pipe at the lower end of a storage tank in which a large amount of filler is stored in advance, and is attached and detached by a band. Freely fixed. In this case, the cylindrical outlet is closed by a band or the like.

[0005] The discharge pipe is closed openably and closably,
When the discharge pipe is opened, the filling in the storage tank is injected into the inside of the bag body through the cylindrical inlet, and when a desired amount is stored, the discharge pipe is closed.

Next, by manually releasing the sticking of the cylindrical inlet to the discharge pipe by the band and closing the cylindrical inlet by tying the cylindrical inlet itself, the flexible container bag is closed. The filling operation of the filler into the is completed.

Next, if the tubular outlet is opened, for example, by transporting the flexible container bag to a desired position, the filling can be discharged from the inside of the flexible container bag through the tubular outlet. .

When the flexible container bag is emptied by the discharge of the filling material, the cylindrical inlet is opened, and each flexible container bag is again flattened as described above. If it is stacked again, the above use can be repeated.

[0009]

From the state in which a number of flexible container bags are stacked in a flat shape as described above, the cylindrical inlets of these flexible container bags are attached to the discharge pipe of the tank. When working or closing the cylindrical inlet after filling the flexible container bag, it is conceivable to mechanize these operations to save labor, but for the following reasons, Mechanization is not easy.

That is, prior to using the flexible container bag, when stacking the flexible container bags in a flat shape, the cylindrical inlet is also formed into a flat shape in the vertical direction. Since it is a simple tubular body having flexibility, when it is simply formed into a flat shape, it does not become a fixed shape.

[0011] For this reason, the cylindrical injection port of the stacked flexible container bags is set to an upright posture, and an attempt is made to externally fit the cylindrical injection port into the discharge pipe. Even if a part of the inlet is gripped or this cylindrical inlet is to be opened, it is not easy to mechanize the above operation because the shape of the cylindrical inlet is not constant as described above.

Further, as described above, when closing the cylindrical inlet, an operation such as tying it is necessary, but such closing operation also requires the same shape of the cylindrical inlet as described above. Since it is not constant, it is not easy to mechanize and save labor.

Conventionally, at the upper end of the cylindrical injection port,
It has been proposed to mount a foldable rigid flange and to mechanize attaching the cylindrical inlet to the discharge pipe or closing the cylindrical inlet with the flange.

However, the above-mentioned flexible container bags are provided with the above-mentioned flanges, respectively, so that the structure of these flexible container bags becomes complicated and the molding thereof becomes complicated. .

The present invention has been made in view of the above situation, and when a flexible container bag is filled with a filling material and transported, it is stacked in a flat shape in advance. The flexible container bag is formed into a shape capable of injecting the filler through the cylindrical inlet into the inside thereof, or after this injection, the work for filling, that is, closing the cylindrical inlet is mechanized, and the flexible container bag is opened.

Therefore, the operation of stacking the flexible container bags 1 on the mounting table 21 in a flat shape in the vertical direction as a whole can be more easily performed. Moreover, since the cylindrical inlet 3 can be laid down in a more accurate and constant shape by its gusset shape, the accuracy of the subsequent mechanical work by the expanding and rising means 27 is also improved. Thus, labor saving of the filling operation can be accurately performed.

The cylindrical injection port 3 is formed into a gusset shape by forming bent portions 15 and 16 extending vertically at a plurality of positions around the axis 6 of the cylindrical injection port 3 so that the cylindrical injection port 3 is in an upright posture. In the free state, the shape injection port 3 has a flat shape in the horizontal direction (X).

For this reason, when the cylindrical injection port 3 is to be closed by the closing means 75, the cylindrical injection port 3 tends to become flat in the horizontal direction (X) and attempts to close itself. The operation of mechanically closing the cylindrical inlet 3 by the closing means 75 can be more easily and smoothly performed.

Therefore, the above filling operation is further labor-saving.

Although the above description is based on the illustrated example, the cylindrical outlet 4 may not be provided.
