A wood pallet in which a plurality of wood plates, which are orthogonal to the spacers and are fixed in parallel and in a plane at predetermined intervals, on both surfaces of the three wood spacers are provided. An improved pallet characterized in that at least side edges of the upper and lower wood boards are made of synthetic resin.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improved pallet, and more particularly to an improved pallet that is lightweight and inexpensive, and has excellent impact resistance, strength, durability and the like.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, when a heavy object is transported, unloaded or unloaded at a factory or the like, the heavy object is loaded on a pallet, and the pallet is transported, unloaded or unloaded by a forklift. As shown in FIG. 1, the above-mentioned conventional pallet has three wood spacers on both sides of which a plurality of wood plates orthogonal to the spacers are fixed in parallel and in a plane at predetermined intervals. It is configured.

[0003]

[Problems that the device is trying to solve]

 Since the above-mentioned conventional pallet is made of high-strength wood such as pine, it has various advantages such as being lightweight, inexpensive, non-slip, and capable of withstanding high loads. However, when using the forks of the forklift on both sides of the spacer in the center during use, the tips of the forklift hit the side of the wooden plate above and below the insertion slot, and the side is easily scratched and many There is a problem that the wood plate is damaged by repeated use and eventually becomes unusable.

As a method of improving the above drawbacks, a pallet made of all synthetic resin has been proposed, but since the bending rigidity of the synthetic resin plate is smaller than that of wood, the thickness of the structural material is increased and the rib However, there is a problem that handleability is deteriorated due to the increase in weight. Further, the synthetic resin structural material is more slippery than wood, and therefore, it is necessary to separately provide an anti-slip agent and the like, and there is a problem that the number of manufacturing steps is not economical. It is therefore an object of the present invention to provide an improved pallet that does not break even after multiple uses without losing the advantages of light weight, low cost, non-slip, load bearing, etc. of wood pallets.

[0005]

[Means for solving problems]

 The above object is achieved by the present invention described below. That is, the present invention provides a wood pallet in which a plurality of wood plates, which are orthogonal to the wood spacers and are fixed in parallel and in a plane at a predetermined interval, on both sides of the wood spacers. This is an improved pallet characterized in that at least the side end portions of the end plates of the wood plates above and below the wood pallet are made of synthetic resin plates.

[0006]

[Action]

 At least the side edges of the upper and lower ends of the wooden pallet of the wooden pallet are made of synthetic resin, and by tying them together with the wooden plate, the tips of the forklifts repeatedly collide with the ends. However, the collision surface is less likely to be destroyed, and therefore the improved pallet will not be damaged even if it is used many times without losing the advantages of the wooden pallet such as light weight, low cost, slip resistance, and load resistance.

【Example】

 The present invention will be described in more detail with reference to the preferred embodiments shown in the drawings. FIG. 1 is a perspective view showing the structure of the improved pallet of the present invention. The improved pallet of the present invention has the same structure as the conventional pallet, but the hatched portion in the drawing is a synthetic resin plate. It is characterized by being composed of. Other configurations of the improved pallet of the present invention except this characteristic portion are the same as those of the conventional wood pallet and are not particularly limited.

As shown in the figure, the pallet has two strength spacers made of wood such as pine and two spacers on both sides and a central spacer. In the illustrated example, the three spacers are columnar with a length a of 1100 mm, a height b of 120 mm, and a width c of 50 mm, but this is an example, and the size is not limited to this. Absent. Above and below the three spacers, a plurality of wood plates orthogonal to the spacers are arranged in parallel and in a plane at appropriate intervals (about 33 mm in the illustrated example). It is firmly fixed. This wood plate has a length of 1100 mm, a width of 120 mm, and a thickness of 20 mm, and has seven sheets arranged on the upper side and seven sheets on the lower side (partially omitted in the drawing). This wood plate is also made of high-strength wood such as pine, and these dimensions are not limited to those shown in the drawings.

In the example shown in the figure, among the above-mentioned wood plates, a part of the plate forming the insertion port into which the forklift fork is inserted (the hatched portion in the drawing) is made of synthetic resin. All of the constituent wood plates may be made of synthetic resin. The synthetic resin plate shown has the same dimensions as the above-mentioned wooden plate except that its width is 30 mm. However, in the present invention, it is not essential that the width is 30 mm. May have a width in the range of 10 to 100 mm, more preferably a width of about 30 to 70 mm.

As the above synthetic resin plate, a polyolefin resin such as a polyethylene resin or a polypropylene resin to which various fillers are added as necessary is preferable in terms of strength and cost. It may be resin, AS resin, ABS resin or the like. The most preferred resin is a low density to high density polyethylene resin. A resin plate made of these resins can be easily manufactured by a known molding method such as extrusion molding or injection molding.

Production of two types of improved pallets of the present invention shown in the drawings (using two types of synthetic resin plates, a high density polyethylene plate (Example 1) and a low density polyethylene plate (Example 2)) Then, as shown in FIG. 1b, the tip of the fork of the forklift was strongly collided with the side end of the pallet, and the number of times until the side end was broken or deformed was counted. As a comparative example, a pallet made of all wood was similarly tested, and the results shown in Table 1 below were obtained. Table 1 From the above results, the improved pallet of the present invention is significantly superior to the conventional all-wood pallet in impact resistance.

[0010]

【effect】

 According to the present invention as described above, by forming at least the side end portions of the end plates of the upper and lower wood plates of the wood pallet from synthetic resin, the tip of the forklift repeatedly collides with the end parts. However, the collision surface is less likely to be destroyed, and therefore, the improved pallet will not be damaged even if it is used many times without losing the advantages of the wooden pallet such as light weight, low cost, slip resistance, and load resistance.
