In order to maintain a predetermined distance between the articles and place them on the pallet, partitions are usually formed integrally or separately between the articles. be done.

When the partitions are integrally formed, special molds are prepared according to the external dimensions of the article to form the pallet.

[Problems to be Solved by the Present Invention] However, in conventional pallets, as described above, when the partitions are integrally formed, a special mold is prepared according to the external dimensions of the article to form the pallet. As a result, a problem arises in that a special mold for the pallet is required depending on the external dimensions of the article.

Therefore, the general-purpose type of pallet body of the present invention was created in view of the above-mentioned problems, and its purpose is to provide a pallet body that does not require a special mold for forming the pallet according to the external dimensions of the articles to be placed. The purpose is to provide a general-purpose type.

[Means for Achieving the Object] and [Operation] In order to achieve the above-mentioned object and object, the present invention provides a method for placing a plurality of articles on a placing surface of a pallet body at predetermined intervals. This is a general-purpose mold for a pallet body that molds a pallet body integrally provided with a partition body, and in order to mold various pallet bodies having different predetermined intervals, the female mold part forming the back surface of the pallet body is a die set having a die set, a die holder movable with respect to the die set, and a piece fixed to the die holder and having a female mold part forming the mounting surface and the partition body divided at a predetermined pitch. It is formed by assembling and hanging pieces together, and integrally includes a partition body for assembling and hanging pieces appropriately according to the external shape of the article and placing them on the placement surface of the pallet body. It functions to form the pallet body to be provided.

[Example] An embodiment will be described below with reference to the drawings.

FIG. 1 shows a perspective view of the appearance of a pallet according to an embodiment. In this figure, an outer box 9 made of, for example, resin molded is also called a transit box, and has reinforcement and holding parts on the outer periphery as shown in the figure. On the other hand, a bottom portion (not shown) is integrally formed to form a container shape, and the pallet body 1 formed by the mold of the present invention is housed inside and used as a pallet. As shown in the figure, this pallet body 1 is integrally formed with a loading surface 1a on which articles 10 are placed and a partition body 2 for keeping articles 10 at approximately equal intervals, and has a clearance slightly larger than the external dimensions of articles 10. We are making sure that we have enough time to set it up. Since this article 10 has various external dimensions, the partition body 2 must be integrally formed at an optimal position depending on the article.

Next, FIG. 2 is a cross-sectional view of a general-purpose pallet body for molding the pallet body 1 shown in FIG. A female mold part 8a serving as the back surface and a side part 8d are formed, and an injection port 8b for injecting a resin material or the like is provided.

Further, the die holder 7, which is moved in the directions of arrows A and B with respect to the die set 8, is provided with a female mold part for forming the above-mentioned mounting surface 1a and the partition body 2. This female mold part is formed by assembling and hooking large pieces 3 and small pieces 4 divided at a predetermined pitch as shown in the figure, and is fixed to the die holder 7. Large frame 3 and small frame 4
The large piece 3 and the small piece 4 are attached to the fixing hole 5a of the fixing plate 5.
After the fixed pillar parts 3a and 4a are inserted, they are latched by the latching plate 6.

FIG. 3 is an exploded perspective view showing how to set the large piece 3 and small piece 4 shown in FIG. To limit the description, the large top 3 is integrally formed with a fixed pillar part 3a as shown in the figure, and while this part is inserted into the fixing hole part 5a of the fixed plate 5, the fixed pillar part 3a is inserted into the fixed pillar part 3a. A fixing groove portion 3b is formed by processing, and an elongated hole portion 6b having one end open at the outer peripheral edge of the insertion hole portion 6a bored at regular intervals in the vertical and horizontal directions of the hanging plate 6 is moved in the direction of arrow C. This fixing groove part 3
As a result of being infiltrated into b, the large piece 3 is fixed as shown in FIG. The small piece 4 is also formed and hung in substantially the same way as the large piece 3, but the height H2 of the small piece 4 is higher than that of the large piece 3.
This height difference is the height of the partition body 2 described above.

Furthermore, the dimensions of the small piece 4 and the large piece 3 are set to ensure the pitch P1 shown in the figure in the width direction, while the pitches P2 and Pi in the vertical and horizontal directions of the fixing holes 5a of the fixing plate 5 match. In this way, when the small piece 4 or the large piece 3 is inserted into any position of the fixing hole 5a, no gap is created between them. Here, if the height H2 of the small piece 4 and the height Hl of the large piece 3 are prepared in advance, the height of the partition body 2 can be set freely, so this should be taken into consideration especially when holding items that easily fall down. be done.

FIG. 4 is an external perspective view of the female mold part set in the die holder 7, and shows the small piece 4 fixed as described above.
The upper surface portion 4S forms a convex portion of the partition body 2, while the upper surface portion 3S of the large piece 3 forms a mounting portion 1a for the pallet body l.

Referring again to FIG. 2, after forming the pallet body 1 by injecting low foam urethane resin from the injection port 8b using the general-purpose pallet described above, the die holder 7 is moved in the direction of arrow B. The cured pallet body l is taken out from the female mold part. Alternatively, the pallet body 1 is formed by vacuum forming.

After producing the required number of pieces in this way, move the hanging plate 6 shown in FIG.
is removed, the pieces are set again on the fixing plate 5 in accordance with the outer shape of the article, the hanging plate 6 is moved in the direction of arrow C to form a female mold part, and the pallet body 1 is molded again. Thereafter, the partition body 2 is similarly formed integrally according to the outer shape of the article.
