Abstract

PROBLEM TO BE SOLVED: To improve the strength and the resistance against weight of a pallet by providing a reinforcing member made of a composite fibrous material on supports of the pallet and the upper and lower faces of panels. SOLUTION: Reinforcing members 32 made of a composite fibrous material are provided on the upper and lower faces of a core member 31 of pallet supports 3 so as to form a sandwich. And further, reinforcing members 42 made of a composite fibrous material are provided on the upper and lower faces of the core member 41 of panels 4 to form a sandwich. The strength of the supports 3 and the panels 4 can be greatly improved by the installation of the reinforcing members 32, 42. Further, since the supporting force is added, the strength of the pallet is increased and hence, loading weight can be increased. Moreover, since the weight of pallet is not increased so much, it does not impose a burden on carrying works. In this way, the strength of the pallet can be securely enhanced and the use efficiency can be improved by providing one layer of reinforcing members 32, 42 on the upper and lower faces of the core members 31, 41 of the supports 3 and the panels 4.

2. Description of the Related Art Pallets can increase the convenience of carrying cargo and are an essential tool for carriers. Conventional wooden pallets were often damaged by insects and corroded by being wetted by water, so some manufacturers developed plastic products. Plastic pallets can help reduce wood use by recovering and recycling them after breakage. As shown in FIG. 1, the structure mainly includes a frame 1 and a face plate 2. Due to the characteristics of the plastic material, there is no risk of insect biting or corrosion, but if the weight is relatively large, it will be damaged. Due to this, the structure has not reached the ideal stage.

[0003]

The pallet and the upper and lower surfaces of the face plate are provided with a reinforcing material made of a composite fiber material.
It is a primary object of the present invention that strength can be greatly increased without changing the size and overall weight of the pallet, thus extending the service life and thus reducing operating costs. is there. It is a second object of the present invention to provide a decorative leather layer made of a vinyl material on the reinforcing material to improve the effects of heat resistance, abrasion resistance, non-slip, ultraviolet rays prevention and the like.

[0004]

Means for Solving the Problems A reinforced material made of a composite fiber material is provided on the upper and lower surfaces of the pallet support and the face plate, so that the strength is greatly increased, the weight resistance of the pallet is increased, and the service life of the pallet is further extended. It is the purpose of the construction of the pallet board of the present invention.

[0005] As shown in FIG. 2, the pallet of the present invention comprises a column 3 and a face plate 4, and is made of a plastic material. The support 3 has a columnar shape, and the face plate 4 has a flat shape. The pillar 3 and the heartwood 31 of the noodle 4,
41 is a plastic plate. Heartwood 31, 41
The upper and lower surfaces are made of composite fibers. Reinforcement 32, 42
As the plastic material of the core members 31 and 41 formed in a sandwich shape, a foam type or non-foam type throat may be used. Further, the plastic material of the face plate 4 can be either a non-hollow material or a hollow material, and the plastic material of the column 3 can be either a column material or a hollow shape. Further, as the material of the composite fiber used for the reinforcing members 32 and 42, glass fiber, carbon fiber, or similar material such as organic fiber can be used. Furthermore, in order to provide the reinforcing members 32 and 42 with elasticity, a woven or non-woven fiber can be used as the reinforcing fiber.

As shown in FIG. 3, the pallet of the present invention is assembled from three laterally oriented columns 3 and a plurality of face plates 4. The upper and lower surfaces of the pillar 3 are mosaic-type irregularities,
The face plate 4 can thereby be fixed in the concave position of the column 3. In addition, there are methods of bonding the columns 3 and 4 or fixing them with screws. The arm of the fork wrist is inserted into the gap between the columns 3, the pallet is lifted, and the carrying operation is advanced. The core material 31 of the support 3 of the pallet of the present invention is provided with a reinforcing material 32 of a composite fiber material on the upper and lower surfaces at the time of manufacture, and is configured in a sandwich shape. The core material 41 of the face plate 4 is also provided with a reinforcing material 42 of a composite fiber material on the upper and lower surfaces at the time of molding, and this is also formed in a sandwich shape. The installation of the reinforcements 32, 42 greatly increased the strength of the columns 3 and 4. Due to the added supporting force, the strength of the pallet increases, and the load can be increased. In addition, the pallets are not heavily weighted so as not to burden the transport operation. In the present invention, only the reinforcing members 32 and 42 are provided above and below the core members 31 and 41 of the column 3 and the face plate 4.
The installation of 42 surely increases the strength of the pallet and improves the efficiency of use.

[0007] As shown in FIG. 7, 5 can be further adhered to the surface of the reinforcing members 32 and 42 of the column 3 and the face plate 4. The decorative leather layer 5 is made of a non-slip plastic material that is resistant to heat, friction, and ultraviolet rays. There may be a pattern on the surface of the decorative leather layer 5, thereby increasing strength, heat resistance,
Not only is the anti-slip and anti-slip effect equipped,
The added value of the pallet appearance can be increased.

[0010] As shown in FIG. 7, the pillars 3 can be combined with each other by attaching them to the face plate 4 or fixing them with screws without providing recesses on the upper and lower surfaces of the columns 3. A decorative leather layer 5 of a vinyl material can be attached to the surfaces of the reinforcing materials 32 and 42 made of a composite fiber material in the same manner as the upper and lower surfaces of the column 3 and the face plate 4, so that the molded pallet can be strengthened, polished, and non-slip. Give better effect such as. Otherwise, in order to prevent rupture due to collision of the hollow column, the foam portion 33 can be packed in the hollow portion, and the strength of the column 3 is increased, thereby avoiding damage due to the collision.

Then, the sleepers are arranged on each of the 1/3 locations on the face plate. The weight is applied to the upper and lower sleepers, and when the load reaches 1.5 times the limit load, the amount of deflection is measured. Then, it is left for 30 minutes with no weight applied, and the amount of deflection at the center of the pallet is measured again. The standard deflection is 45 mm or less. FIG. 8 shows the embodiment.
