Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention can be installed in supermarkets, sushi restaurants, etc.
The present invention relates to a forming machine capable of forming a packaging container at its own store if necessary.

(Problems to be Solved by the Related Art and Invention) A synthetic resin packaging container used in supermarkets, shops, etc. is mainly formed of expanded polystyrene plate, cardboard, warp wood, etc., and a forming means in case of using expanded polystyrene plate For example, Japanese Utility Model Laid-Open No. 57-169509 and Japanese Patent Laid-Open No. 51-127174.
As shown in the publication, each side plate of the expansion plate is erected and heat is welded between the adjacent side plates, or the Styrofoam plate is softened by heat and formed into a container by using a molding die. This packaging container is mass-produced at each factory and transported to a user such as a supermarket for use. In addition, containers made of wood such as wood are also produced at each factory and provided to users.

However, since this packaging container is very bulky, it requires a large-area warehouse to store it as inventory,
Further, the transportation is inefficient and causes a cost increase. There are various types of assembling cardboard, but those that are easy to assemble at the time of use have a complicated structure and are expensive, and those that are inexpensive are complicated to assemble.

Therefore, the present inventor provides a plate-shaped container material, that is, a development plate, by a conventional manufacturer, and when a user such as a supermarket produces a container immediately before use, inventory storage and transportation are performed in the state of the development plate. I thought that it would be possible to make the distribution of packaging containers very rational. However, in the production of packaging containers, since there is no particular problem because a large quantity of individual products are produced, in order to have the user of the container install the container forming machine to be used in the factory, the installation location, Needless to say, it is inconvenient to handle. Especially on the user side, a large amount of various types (types of container size) and a small amount are required.

Therefore, the present inventor has proposed a simple forming machine for packaging containers that can handle a wide variety of products.

(Means for Solving the Problem) A food packaging container forming machine according to the present invention uses a spreading plate in which side plates are arranged on the four circumferences of a bottom plate, and the side plates are erected and adjacent side plates are bonded to form a container. A forming machine for forming a box-making cassette body having inclined side surface portions for adhering the side plates by erecting the side plates of the spreading plate, and a mounting portion of the box-making cassette body and the mounted box-making cassette body. It comprises a pressing mechanism for pushing out the central portion of the plate and a main body having a container outlet formed on the pushing side of the mounting portion of the box-making cassette body.

(Working) Attach a box-making cassette body corresponding to a container of a predetermined size to the main body, insert a development board made of foamed resin plate, cardboard, warp wood, etc. on the box-making cassette body and use the pressing mechanism to open the development board. When press-fitted into the box-making cassette body, the side wall of the expansion plate stands up due to the inclined wall surface portion, and the container material itself or the previously applied adhesive is melted by the heating device, or the adhesive is applied by the adhesive application device. A predetermined part of the side plate is adhered to form a container. When the size of the container to be formed changes, the box-making cassette body corresponding to the size of the container may be replaced.

(Example) Next, the Example of this invention is described.

<First Embodiment> FIGS. 1 to 3 show the first embodiment. In the first embodiment, a box making mechanism provided with a heating device is used as a cassette member.

The forming machine comprises a main body 1 and a box-making cassette body 2. The main body 1 has a box shape as a whole and is provided with a pressing mechanism 11, and a cassette mounting portion 12 and a take-out portion 13 are provided on the front surface. The pressing mechanism 11 includes an air cylinder 111 arranged above the cassette mounting portion 12 and a pressing plate 11 connected to the piston of the air cylinder.

The box making cassette body 2 has a positioning wall plate 23 and an inclined wall surface.
It is necessary to prepare several kinds of holes with different sizes formed in 21. Especially, the raw material (delayed material of the expansion plate for forming the packaging container) occurs during manufacturing. The directional property is provided, and the resistance when the side plate is erected differs between the case where the side plate portion is erected along this direction and the case where the side plate portion is bent in a direction orthogonal to the direction. If the state is the same for each wall surface, the upper edge portion of the container formed by the difference in the resistance becomes uneven, so that the inclined wall surface 21 has a higher resistance and a smaller resistance. Are formed so that the adjacent wall surfaces are slightly different in shape so that they stand up late and finally become the same standing state.

Thus, a developing plate A as shown in FIG. 3 is prepared in advance, the box-making cassette body 2 corresponding to the developing plate A is mounted on the cassette mounting portion 12 of the main body 1, and the heating plate 22 is energized. When the accumulator 115 is ready to form the packaging container B when the predetermined high pressure air is stored, the heating plate 22 is heated and the expansion plate A is inserted into the upper part of the box making cassette body 2. In addition, when the expansion plate A is pushed into the hole formed by the inclined wall surface 21 by aligning with the positioning wall plate 23 and operating the cylinder 111, each side plate a of the expansion plate A stands up and The edge b is brought into contact with the heating plate 22 and melted and welded to each other to form the container B.
The container B is taken out from the take-out section 13 and used.

Therefore, when forming containers of different sizes, it is only necessary to replace them with a predetermined box-making cassette body, and a single forming machine can easily form many kinds of containers.

In particular, when forming a rectangular box-shaped container, the expansion plate A
If the welding end edge b of (1) is made to protrude more than the conventional end edge b (shaded shape of partially enlarged cross-section in FIG. 3), the formed container B becomes an accurate rectangular box-shaped container. In the conventional state, the styrofoam material melts and the volume of the styrofoam material decreases slightly after welding and solidification. This improves the point that the strength of the welded portion is reduced.

Further, in the first embodiment, the side edge b of the spreading plate A may be used in advance, such as a hot-melt type adhesive agent, which is preliminarily coated with an adhesive capable of adhering when heat is applied. However, if a pressure-sensitive adhesive is applied instead of the adhesive, the heating device described above is not required.

<Second Embodiment> FIGS. 4 and 5 show a second embodiment. In this second embodiment, two cassette members, a developing plate supply cassette body and a box making cassette body, are used. .

1 and a positioning portion 412 having a positioning wall surface of the expansion plate A. Further, the box making cassette body 42 is a development plate A.
The side wall a is provided with an inclined wall surface and a heating plate.

Thus, the predetermined supply cassette body 41 and the box-making cassette body 41 are mounted on the supply receiving portion 34 and the cassette mounting portion 32 of the main body, respectively, and the developing plate A is positioned by the feeding mechanism 341 from the supply portion 411 of the supply cassette body 41. When it is sent to the portion 412 and the pressing mechanism 31 is operated, the expansion plate A is pushed into the inclined wall surface and the side plate a
And the side edge b is welded and the container B is formed.

Therefore, the size and design (pattern) to be formed can be selected by replacing the supply cassette body 41, and the expansion plate supplied by the supply cassette body 41 can be replaced by the corresponding box-making cassette body 42 to produce the product. A box can also be easily implemented.

In the above-described first and second embodiments, when the pressing mechanism pushes down the expansion plate to the extraction portions 13 and 33 at once, the side edges b of the expansion plate A are not welded (cooling and solidification of the molten portion). There is also a case where it reaches the take-out section and is not boxed. The pressing mechanism is operated so that the standing state of each side plate a of the expansion plate A is maintained for a predetermined time.
