Description

[Detailed explanation of the invention] [Industrial field of application] The present invention has the ability to
This is a synthetic resin pallet with holes as large as possible on the product placement surface in order to reduce costs by reducing the amount of resin used as a constituent material, and ease of handling due to weight reduction. A plurality of strip-shaped plate portions each of which has a mounting surface parallel to or substantially parallel to a side portion different from the side portions between opposing side portions, and these strip-shaped plate portions and said side. It is constructed with a plurality of rib-like plate parts formed in such a manner that rib-like pieces that are X-shaped or approximately X-shaped in plan view are continuously arranged between adjacent side parts. Regarding the palette.

[Conventional technology]

In the conventional pallet of this kind, as shown in FIG. 4A, the X-shaped rib-like pieces 03a, Intersection 03 of 03a
b, 03b were arranged to be located on a straight line along a direction perpendicular to the longitudinal direction of the band-shaped plate portion 02.

[Problem that the invention attempts to solve]

In this type of pallet, a large number of small articles are lined up and packaged in a columnar or cylindrical shape, and the articles are arranged in parallel along the longitudinal direction of the strip plate in a direction perpendicular to the longitudinal direction of the strip plate. It is sometimes used to transport and store items placed in a certain state. Incidentally, a columnar or cylindrical article is supported in a line or almost line contact state with the mounting surface.

When placing a wrapped cylinder or cylindrical item,
According to the conventionally constructed pallet, the support conditions of the rib-shaped plate sections for each of the articles lined up in the longitudinal direction of the strip-shaped plate section vary greatly from one article to another, so that some articles are easily deformed and damaged.

Based on FIG. 4A, the above-mentioned drawbacks will be explained while considering the placement situation of the article.

Comparing the article placed on the A-A line and the article placed on the B-B line, the article on the A-A line has a rib-like plate located between the side part and the band-like plate part. The article is supported at the point corresponding to the intersection of the X-shaped rib-like pieces in the rib-like plate part located between the side and adjacent strip-like plate parts, whereas the article on the line B-B is supported at the point corresponding to the intersection of the Some rib-like plate parts located between the part and the band-like plate part and rib-like plate parts located between adjacent band-like plate parts are not supported. Also, A
- As a mounting state other than on line A and line B-B,
Considering the case where the article is placed on the line C-C as a representative example, the article is supported at two locations in the longitudinal direction by each rib-like plate portion.

As is clear from this invention, in the pallet of the conventional structure, the state in which the articles are supported by the rib-like plate portions varies greatly depending on the articles lined up in the longitudinal direction of the strip-like plate portions.

By the way, when placing articles on a pallet, it is desirable to support them not only by the side portions or the band-like plate portions but also by the rib-like plate portions. In other words, the part of the article located between the side portion and the strip-shaped plate portion or between adjacent strip-shaped plate portions will be bent downward and deformed if the support is poor. When the article is deflected downward between the side portion and the strip-shaped plate portion or between adjacent strip-shaped plate portions, the total amount of deflection deformation becomes large, and therefore, In the case of items packed with many small items lined up,
Since the wrapping paper is easily damaged by the tensile force associated with bending and deformation, there was a risk of deformation and damage.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to eliminate the conventional drawbacks through simple improvements.

[Means for solving problems]

The characteristic configuration of the synthetic resin pallet according to the present invention is that, at the intersection of the X-shaped rib-like pieces in each of the rib-like plate parts, which are elements constituting the article placement surface, among the plurality of strip-like plate parts, The intersection points of the rib-like plate parts located on both sides of at least one band-like plate part are arranged so that their positions are shifted along the longitudinal direction of the band-like plate, and the functions and effects are as follows. That's right.

[Effect]

In other words, if the intersection points of the rib-shaped plates located on both sides of the strip-shaped plate are misaligned along the longitudinal direction of the strip-shaped plate, the rib-shaped plate located on one side of the strip-shaped plate may Even if the article is not supported, the rib-like plate portion located on the other side of the strip-like plate portion supports the article. This corresponds to A-
This corresponds to a state in which an article is placed on line A or line B-B. Furthermore, if we consider the case where the article is placed on the C-C line as a representative example of the placement state other than on the A-A line or the B-B line, it is assumed that the article is supported by each rib-like plate part. Become.

In other words, according to the configuration of the present invention, either the rib-shaped plate portion located between the side portion and the strip-shaped plate portion or the rib-shaped plate portion located between the adjacent strip-shaped plate portions can hold the article. Compared to the case where the article is deformed downward between the side portion and the strip-shaped plate portion or between the adjacent strip-shaped plate portions because the article is supported,
The amount of deflection deformation of the entire article becomes smaller. Along with this, for items that are packed with many small items lined up,
This makes it possible to reduce the tensile force that acts on the wrapping paper as it bends and deforms.

[Effect of idea]

Therefore, it is possible to reduce the tensile force acting on the wrapping paper of an article packed with a large number of small articles side by side, thereby suppressing deformation and damage to the article due to breakage of the wrapping paper, etc. It has become possible to easily place cylindrical or cylindrical articles packed in large numbers side by side.
