Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to pallets, and more particularly to pallets made of aluminum alloy.

Prior Art Aluminum alloy pallets are lighter, nonflammable, and corrosion resistant than wooden pallets, and are also easier to clean and dry, so they are widely used in the pharmaceutical, food, and paper products and book industries. It tends to be used.

As the aluminum alloy pallet described above, for example, one disclosed in Japanese Patent Laid-Open No. 54-86147 is known.

Problems with the Prior Art However, in the conventional pallet disclosed in the above publication, each deck board (center board) is attached to each digit (leg) via a spacer in the width direction, so there is a gap between each deck board. A certain gap (corresponding to the width dimension of the main body of the spacer that fixes the centerboard) is formed.

Therefore, for example, when a relatively small high-tech product, which has been increasingly handled in industry in recent years and is extremely sensitive to dust, is placed on the conventional pallet, the product can be removed from the gap between the deck boards. This causes problems such as spillage and dust adhering to the gaps, which deteriorates the quality of the products on the pallet.

Furthermore, in the conventional pallet described above, each deck board and each digit are connected only at their respective intersections to maintain the shape of the pallet, so the load acting on each deck board is applied to each digit separately. There was also the problem that the strength was relatively weak.

Purpose of the invention The present invention was devised in view of the above circumstances, and by changing the structure of the pallet, it is possible to handle small high-tech products, for example, and the strength of the pallet itself is improved. The purpose is to provide a palette that allows for

Structure of the invention In order to achieve the purpose of air conditioning, the main means adopted by the present invention are a pair of side beams arranged in parallel on the left and right, and a middle part between this pair of side beams. and a plurality of deck boards that are attached to both upper and lower surfaces of each of the girders and are arranged in a flat plate shape, and the deck boards are arranged at both left and right ends of the deck boards. In the pallet made of aluminum alloy, the deck boards are arranged side by side in close contact with each other, and the adjacent parts of the deck boards are engaged with each other so as to be mutually connected. A locking portion is formed to mutually restrict movement in an upward/downward direction, and an engaging portion for connecting the deck board and each digit is provided in the longitudinal direction on both upper and lower surfaces of each digit, and the engaging portion is provided in the longitudinal direction of each digit. This is a pallet in which a connecting member that slidably engages with the joint is fixed to the deck board.

Embodiments Hereinafter, embodiments embodying the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

It should be noted that the following example is an example embodying the present invention, and is not intended to limit the technical scope of the present invention.

Here, FIG. 1 is a perspective view of a pallet according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line B-B in FIG. 1, and FIG. 3 is a partially broken side view taken along the arrow C in FIG. It is a diagram.

In the aluminum alloy pallet A according to this embodiment, as shown in Figs. A plurality of deck boards 4 are attached to the upper and lower surfaces of each girder and are arranged in close contact with each other. Both longitudinal ends and the pair of side beams 1 and 2 are welded to each other.

Further, a protection member 6 is welded to the insertion port side 5 on the side surface of the deck board 4.

Above side beams 1, 2 and middle beam 3 (see Figure 2)
are made of extruded aluminum material each having a rectangular hollow part 7, and the upper/lower walls 8, 9 are provided with an engaging part 1.
A groove 11 having a diameter of 0 is integrally molded. A blind portion 12' for concealing the opening end face of the deck board 4 extends above/below the side wall 12 of one of the side beams 1 and 2.

Above deck board 4 (see Figures 2 and 3)
is a rectangular hollow part 1 partitioned by a reinforcing part 13
4 and 14', and the side walls 15 and 16 have locking parts 15' and 1
6' are each integrally molded. Furthermore,
Each of the above digits 1 on the inner surface 4' of the deck board 4,
A connecting member 17 having an engaging portion 18 is welded to the connecting portion between the connecting members 2 and 3 using a through hole 17' formed in the center of the connecting member 17.

In addition, the locking portions 15', 1 of the deck board 4
6' is for restricting upward/downward movement of the adjacent deck boards 4 by interlocking the locking parts 15' and 16' with each other.

The connecting member 17 sequentially moves and guides the deck board 4 along the longitudinal direction inside each groove 11 of each girder 1, 2, and 3, and engages the engaging portion 18 of the connecting member 17 with the groove 11. This is for connecting each of the girders 1, 2, and 3 to the deck board 4 by engaging the portions 10 with each other in the vertical direction.

Since the pallet A is constructed as described above, there are no gaps between the deck boards 4, and since there are no protruding parts on the whole, the pallet A has a structure that is difficult to attract dust.

Also, the locking portions 15', 1 of the deck board 4 are
The deck boards 4 are mutually reinforced by the interaction of the deck boards 6', and welding work between the deck boards 4 can be omitted.

Furthermore, when assembling the pallet A, the connecting member 17 of the deck board 4 guides the deck board 4 to the normal position along the 1st, 2.3rd grooves 11 of each digit, making the assembly work easier. Due to the action of the engaging portion 18 and the engaging portion 10 of the groove 11, the pallet A has a stronger structure, and the welding operation between the deck board 4 and the hollow 3 can be omitted.

Note that, as in the present embodiment described above, the protective member 6 is attached to the locking portion 1 on the insertion port side 5 of the side surface of the deck board 4.
5' and the side wall 1 of the deck board 4
By welding to the deck board 5, for example, when the tip of the claw of the pallet transport lift hits the side of the deck board 4,
This makes it possible to protect the

Effects of the invention As described above, the present invention has a pair of side beams arranged parallel to each other on the left and right, and a hollow groove placed in the middle of the pair of side beams parallel to the set of side beams. and a plurality of deck boards attached to the upper and lower surfaces of each girder and arranged in combination in a flat plate shape, and both left and right ends of the deck boards are fixed to the set of side girders. In the pallet made of aluminum, the deck boards are arranged side by side in close contact with each other, and locking portions are provided at adjacent portions of the deck boards to engage with each other and restrict mutual upward/downward movement. The deck board is provided with engaging portions for connecting the deck board and each girder in the longitudinal direction on both upper and lower surfaces of each girder, and a connecting member that slidably engages with the engaging portion. Since this pallet is characterized by being firmly fixed to the deck boards, there are no gaps between the deck boards. For this reason,
For example, it is possible to handle high-tech products that are small and dust-free, and since the structure of the pallet is almost integrated, it is possible to provide a pallet that can improve the strength of the pallet itself. .
