Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a packaging container suitable for automatically supplying materials to a shrink molding machine, an injection molding machine, or the like.

<<Prior Art>> For example, equipment for compression molding glass fiber reinforced plastic materials uses bulk mold compound (abbreviated as "BMC") as a material.
If this material is stored bare, the styrene monomer, which is the crosslinking agent in the material, will scatter and escape.
Therefore, as shown in FIG. 5, after storing the material 2 in the bag-shaped film packaging material 1, the packaging material 1
The upper opening of the container is tied and sealed with a rubber band or the like, and the container is further stored in a container 3 such as a cardboard box. Then, the upper and lower flaps 4 of the container 3 are closed, and the container is further sealed with packing tape 5 or the like, and the container is transported in this state.

<Problems to be solved by the invention> For this reason, the material 2 transported to each device is removed from the container 3 by peeling off the cam tape 5 each time.
Furthermore, it is necessary to take out the material from inside the packaging material 1, and this operation requires manpower.

Furthermore, although devices such as compression molding machines that automatically feed the bulk molding compound material 2 have been developed today, the process up to taking out the material 2 from within the packaging material 1 relies on manual labor. That is, the material 2 is manually removed from the container 3 together with the packaging material 1 by peeling off the packing tape 5, and the material 2 is also manually removed from the packaging material 1 and placed on the hopper supply conveyor. After that, a conveyor automatically transports it to the reserve hopper and supplies it. Therefore, even if an automatic feeding device is used, it still relies on manual labor and has not yet reached full automation. As a result, there was a problem of high costs.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a packaging container that can completely automate the supply of materials by an automatic machine.

<Means for Solving the Problems> In order to achieve the above object, the present invention folds and closes the upper and lower openings of the box-shaped main body with a plurality of flaps formed integrally with the box-shaped main body, and at least This packaging container stores a material made by folding and enclosing a packaging material with its lower part open, and is characterized in that the flap on the upper surface side is provided with a hole for guiding a part of the packaging material to the outside.

[Operation] According to this configuration, a part of the packaging material used to wrap and store the material is stored with it protruding from the hole at the top, and the part of the packaging material protruding from the hole is removed by the chuck of the automatic machine. By grasping and lifting the
The weight of the material causes the bottom of the packaging material and the lower opening of the box-shaped body to open, allowing the material to fall and provide automatic feeding.

<<Example>> Hereinafter, an example of the present invention will be described with reference to the drawings.

1 to 4 show a packaging container according to an embodiment of the present invention.

In FIGS. 1 to 4, the packaging container 6 has a main body 7 made of cardboard or the like and shaped like a box. Furthermore, flaps 8 are provided on the four opposite sides of the upper and lower openings of the main body 7 and extend integrally from the main body 7, and each flap 8 can be bent at the boundary with the main body 7. . Then, when each flap 8 is bent inward approximately 90 degrees,
Each upper opening and lower opening can be closed by a respective flap 8. In addition, each flap 8 has an upper opening.
A notch 9 is provided on each side of the free tip side of the flap 8 on the long side, so that a circular hole 10 is formed when the flap is closed.

The packaging container 6 thus formed is made of a material 11 such as a bulk mold compound.
When storing, each flap 8 on the lower side is
Fold inward 90 degrees to close the bottom opening,
In this state, it is placed on a transport pallet and prepared with the top opening open. Further, prior to storage, the material 11 is preliminarily stored in a cylindrical film packaging material 12 with both ends open. This packaging material 12 only needs to be open at least at its lower part. As shown in FIG. 3, the material 11 housed in the film packaging material 12 is folded inward at the lower open part 13 of the film packaging material 12 under the material 11, and the material 11 is placed in close contact with the lower surface of the material 11. into a folded state. Then, in this state, it is stored in the packaging container 6 from the open top side. Then, the folded lower open portion 13 is pressed between the inner surface of the bottom flap 8 of the packaging container 6 and the material 11, resulting in a sealed state. Furthermore, when the upper part of the film packaging material 12 is bundled and bound with a rubber band 14 or the like, the material 11 becomes the film packaging material 12.
It becomes sealed inside. Next, in this state, the upper flap 8 is folded inward and closed. In this case, the bundled portion 15 of the bundled film packaging material 12
The flaps are closed with the flaps protruding outward from the holes 10, and packing tape 16 is applied to a portion between the flaps 8, 8 to prevent the upper opening from opening, and storage is completed. This state is shown in FIGS. 2 and 3, where the lower flap 8 of the packaging container 6 is merely folded and not sealed with adhesive tape 16 or the like.

Then, the packaging container 6 containing the material 11 in this manner is carried on a pallet to, for example, a hopper supply conveyor, where it is maintained until it reaches the preliminary hopper of the molding machine. In addition, when supplying the preliminary hopper material 11 of the forming machine,
The packaging container 6 remains in the state shown in FIGS. 2 and 3.
The binding portion 15 protruding from the hole 10 of the fourth
As shown in the figure, pick it up using the chuck 17 on the automatic feeder side. Then, the packaging container 6 opens with the upper flap 8
Since it is closed with packing tape 16, it is lifted up together with the film packaging material 12. On the other hand, the lower flap 8 of the packaging container 6 is not closed and is therefore opened. In addition, since the lower side of the film packaging material 12 is only folded, the weight of the material 11
It slips out and falls into the reserve hopper to be supplied.
After dropping the material 11, the packaging container 6 and the film packaging material 12 are moved outside the conveyor and processed.

Therefore, the material 1 using this packaging container 6
In the automatic supply method 1, the work after storing the material 11 can be automated until the material supply is completed without any manual intervention.

In the above embodiment, the material 11 to be stored is a bulk mold compound used in a compression molding machine as an example, but the present invention is not limited to this material and can be applied to other materials.

<<Effects of the Invention>> As explained above, the packaging container of the present invention enables complete automation of material feeding in an automatic machine by using this container, and can reduce manufacturing costs.
