Abstract

PROBLEM TO BE SOLVED: To allow articles to be stably stacked in multiple stages by forming an upper face fitting protrusion protruding upward on an upper face of a hill formed on a mount board and by concaving a bottom of a recess or a stage to form a lower fitting part protruding from a lower face of the mount board. SOLUTION: An upper fitting protrusion (m) is provided to protrude upwardly from an upper face of an outer hill formed adjacent to a rim of a mount board 1. In addition, a bottom 3' of an annular recess is concaved downward to form a lower face fitting protrusion (d) protruding downwardly from a lower face of the mount board 1. When the transfer tray T is put over a pallet, side walls 2 hanging downwardly from four side rims of the mount board 1 are positioned close to side faces of the pallet, as well as the lower fitting protrusion (d) is fitted into a through hole formed on an upper deck board. This limits horizontal movement of the transfer tray T with respect to the pallet, thereby improving stability of articles stacked in multiple stages via the transfer trays T.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article placed on a pallet in multiple stages and a transport tray disposed between pallets or between articles.

[0002]

2. Description of the Related Art Heretofore, there has been known a transport tray in which side walls are formed by hanging down from four sides of a rectangular plate material. Then, the transport tray is placed on the upper deck board of the pallet, the articles are placed on the article placing surface of the transport tray, and then, on the articles placed on the article placing face of the transport tray, Furthermore, articles are stacked in multiple stages via a transport tray, such as placing a transport tray and placing articles on the article placement surface of the transport tray. The transport tray is also placed on the uppermost article. In addition, a pallet in which articles are stacked in multiple stages is similarly stacked on a pallet in which articles are stacked in multiple stages via a transport tray.

[0003]

A transfer tray having a side wall which is suspended downward from four sides of a plate having a rectangular planar shape is placed so as to cover an upper deck board of a pallet. Since the transfer tray is formed of a thin plate made of synthetic resin, the side wall of the transfer tray has no rigidity and is easily deformed. Therefore, there has been a problem that the pallet is easily moved in the lateral direction with respect to the upper deck board, and the articles in which the articles are stacked in a multi-stage manner via the transport tray have poor stability and are easily collapsed.

Also, when a pallet in which articles are stacked in a multi-stage manner is stacked on a pallet in which articles are stacked in a multi-stage manner via a transfer tray, the pallet is also positioned upward. Since there is no engaging means for preventing lateral movement between the lower surface of the pallet and the transport tray on which the pallet is placed, there is a problem that the pallet is easily broken.

An object of the present invention is to solve the problems of the conventional transport tray as described above and to provide a transport tray capable of stably stacking more articles in multiple stages. .

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides an upper surface fitting projection which projects upward from a hill formed on a mounting plate on a transport tray. And a lower surface of the mounting plate which can be fitted into a through-hole or a recess formed in the upper deck board of the pallet by recessing a bottom surface or a step portion of the concave portion formed in the mounting plate downward. And a lower surface fitting projection protruding downward from the projection.

In the present embodiment, an example is shown in which a substantially cylindrical tire wheel is placed on the transport tray T, so that the recess 3 is formed as an annular recess, and the loading plate 1
Has six annular concave portions 3 as an example. The annular concave portion 3 is formed inside the annular concave portion 3, the inner hill portion 4 having a circular planar shape higher than the bottom surface 3 ′ of the annular concave portion 3, and the annular concave portion 3 formed outside the annular concave portion 3.
Is formed so as to be sandwiched between a plurality of outer hills 5 higher than the bottom surface 3 ′. In this embodiment, as shown in FIG. 1, the annular recesses 3 are arranged in parallel to each other, two rows on the left and right and one row at the center of the two rows, for a total of three rows. Are provided with two annular concave portions 3 respectively.

M is an upper surface fitting projection projecting upward from the upper surface of the outer hill portion 5 formed adjacent to the edge of the mounting plate 1. May project from the entire outer hill 5 formed adjacent to the edge of the mounting plate 1, or may project from an appropriate outer hill 5. In the present embodiment, in FIG. 1, one is disposed on each of the outer hills 5 a disposed on the left and right of the annular recess 3 a above the central row, and one is disposed in the middle of the left and right rows of the annular recess 3.
Each of the outer hills 5b having a substantially triangular planar shape has one
A total of six upper surface fitting projections m, two in the outer hill portion 5c having a substantially trapezoidal planar shape and arranged along the annular concave portion 3b below the central row, are provided. .

Reference numeral d denotes a lower surface fitting projection d formed by recessing the bottom surface 3 ′ of the annular concave portion 3 and projecting downward from the lower surface of the mounting plate 1. Are formed on the bottom surface 3 ′ of the annular concave portion 3 adjacent to the edge of the mounting plate 1.
In the present embodiment, in FIG. 1, two annular recesses 3
On the bottom surface 3 ′ of the annular concave portion 3 c located above the left and right rows of
A total of six lower surface fitting projections d, one each, are formed on the bottom surface 3 'of the annular recess 3c located below the left and right rows of the annular recess 3, respectively.

Next, a method of using the above-described transport tray T will be described.

First, the transfer tray T is placed on the pallet P, and a large number of through holes p3 are formed at least near the edges of the upper deck board p1 and the lower deck board p2 of the pallet P. Therefore, the transfer tray T
Is placed on the pallet P, the lower surface fitting projection d projecting downward from the lower surface of the mounting plate 1 of the transport tray T fits into the through hole p3 formed in the upper deck board p1. Will do. As described above, the transport tray T placed on the pallet P has the side wall 2 hanging downward from the four side edges of the mounting plate 1 arranged close to the side surface p4 of the pallet P, The lower surface fitting projection d protruding downward from the lower surface of the mounting plate 1 is fitted into the through hole p3 formed in the upper deck board p1, so that movement in the horizontal direction with respect to the pallet P is restricted. Therefore, the stability of the articles stacked in multiple stages via the transport tray is improved.

In addition, the pallets P, on which the articles W are stacked in multiple stages, are also stacked on the pallets P, on which the articles W are stacked in multiple stages, via the transport trays T. In this case, the loading plate 1 of the transport tray Ta arranged at the top of the pallet P '
Upper surface fitting projection m protruding from the outer hill portion 5 formed at
Will fit into the through-hole formed in the lower deck board p2 of the pallet P ″ placed on the transport tray Ta. Therefore, the pallet P ″ is arranged at the top of the pallet P ′ located below. With respect to the transport tray Ta, the pallet P ″ placed on the transport tray Ta is restricted from moving in the horizontal direction, so that the pallets P stacked in multiple stages via the transport tray are restricted. Stability is improved.

At an appropriate corner of the transport tray T, a part of the step 6 having the same height as the bottom surface 3 'of the annular recess 3 is recessed downward, and the lower surface fitting projection d as described above is formed. May be formed so that the lower surface fitting projection d is fitted into the through hole p3 formed in the upper deck board p1. Of course, it is also possible to form the lower surface fitting convex portion d on both the bottom surface 3 ′ of the annular concave portion 3 and the step portion 6,
Alternatively, the lower surface fitting projection d can be formed on only one of the step portions 6. Further, instead of the through hole p3, a concave portion into which the lower surface fitting projection d can be fitted can be formed in the upper deck board p1.

Further, in the above-described embodiment, the upper surface fitting projection m which fits into the through-hole or the recess formed in the lower deck board p2 of the pallet P is projected from the outer hill portion 5. However, the upper surface fitting convex portion m can be protruded from the inner hill portion 4. In this case, as a matter of course, a through hole or a depression is formed in the lower deck board p2 at a position corresponding to the upper surface fitting projection m protruding from the inner hill portion 4.

[0015]

Since the present invention is configured as described above, it has the following effects.

[0016] The stability of articles stacked in multiple stages via the transport tray is improved.

Also, when a pallet in which articles are stacked in a multi-stage manner is stacked on a pallet in which articles are stacked in a multi-stage manner via a transfer tray, a transfer tray is also provided. Since the horizontal movement of the pallets placed on the pallet is restricted, the stability of the pallets stacked in multiple stages via the transfer tray is improved.
