[Problems to be solved by the device]

 However, the above-mentioned corrugated cardboard cargo pallet simply consists of multiple corrugated cardboard sheets fixed together with an adhesive, and due to the flexibility of the corrugated cardboard, twisting may occur during transport, or the cargo may be stacked during storage. There are problems that it may collapse, its impact resistance is weak, and that the side edges of the corrugated cardboard sheet are not hardened so that they tend to be softened and damaged, resulting in extremely poor water resistance and corrosion resistance. It was

This invention solves the above-mentioned problems and provides a low-priced cargo container pallet that is made of paper containers and is easy to manufacture with excellent durability that is excellent in impact resistance, water resistance, and corrosion resistance. It is intended to be provided.

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a part of each constituent element of the paper container cargo handling pallet of the present invention. In FIG. 1, reference numeral 1 denotes a paper container cargo handling pallet of the present invention. The cargo handling pallet comprises a rectangular loading plate 10, three narrow bottom plates 20, and the loading plate 10 and the bottom plate 20. It is composed of nine pedestals 30 which are arranged between the facing surfaces and which fix the both.

The stacking plate 10 is composed of ten cardboards 11 cut into a rectangular shape, and a corrugated cardboard sheet 12 having a three-layer structure with two cardboards 11 interposed between the cardboards 11 (see FIG. 1). The core material 14 is formed by fixing the contact surfaces to each other by means of not shown), and four cardboards 15 and two cardboards 16 of the same shape are formed on the upper surface 11a and the lower surface 11b of the core material 14, respectively. And are integrated in a laminated form with an adhesive (not shown), and the total thickness is about 15 to 25 mm, which is 20 mm in this embodiment.

The bottom plate 20 is made of the same material as that of the stacking plate 10 and has a narrow width. The bottom plate 20 is arranged on the lower surface of the stacking plate 10 at regular intervals in the same row direction. The pedestal 30 is made of a high-rigidity cylindrical paper tube, and has a horizontal pressure resistance of 170 kg / cm ² and a vertical pressure resistance of 1200 kg / cm ² . As is often seen in the inverted view of FIG. 2, the stacking plate 10 has circular recesses 17 formed in the lower surface portion 10a so as to be separated in a row for a certain period of time. , 8 along each side edge of the lower surface 10a and 1 in the center, a total depth of 11 to 21 mm from the flat portion of the lower surface 10a. When the thickness is 20 mm, the depth of the recess 17 is preferably 16 mm.

Reference numeral 23 denotes a circular concave portion formed on the upper surface portion 20 a of the bottom plate 20, and the concave portion 23 has a diameter equal to that of the concave portion 17 formed on the lower surface portion 10 a of the stacking plate 10 and a position corresponding to the concave portion 17. It is provided in. The upper end portion 30a and the lower end portion 30b of the pedestal 30 are fitted into the recesses 17 and 23 and fixed by an adhesive, so that the stacking plate 10 and the bottom plate 20 can be separated from each other. They are connected as shown in 3.

As described above, the outer end surfaces 18 and 19 of the stacking plate 10 and the bottom plate 20 which are connected to each other by the pedestals 30 are end-sealed and hardened by the superhard thermosetting adhesives 40 and 41, respectively. Is done. Reference numeral 42 is a resin film that is coated and adhered to the outer surfaces of the laminated plate 10 and the bottom plate 20.

According to the paper container cargo handling pallet of the present invention configured as described above, it is light and easy to handle when a load is placed on the upper surface of the stacking plate 10 and is packaged and transported together with the stacking plate 10. At the same time, even when the luggage is placed on the upper surface of the loading plate and is moved by the forklift fork portion (not shown), it is possible to use the gap between the loading plate 10 and the bottom plate 20 formed by the pedestals 30. It's easy.

Further, according to the above-mentioned embodiment, the outer surface of the stacking plate 10 and the bottom plate 20 is coated and adhered with the resin film. However, instead of the resin film, wax or the like is applied to the outer surface to perform waterproof treatment. It is possible to provide a cargo-handling pallet with excellent water resistance even with a structure that applies the above.

[0016]

[Effect of device]

 As described above, according to the pallet for cargo handling made of paper containers according to the present invention, a plurality of cardboard sheets having a loading plate and a plurality of corrugated cardboard sheets interposed between these cardboard sheets are laminated and pressure-bonded with an adhesive to form a core material. The core material is formed, and a plurality of cardboards are laminated on the upper and lower surfaces of each core material to be pressure-bonded and integrated, and each side end surface is end-sealed with a thermosetting resin, resulting in strong impact resistance. It is possible to make a stacking board made of paper containers that is excellent in water resistance and corrosion resistance, and since the stacking board and the bottom board can be firmly connected by the pedestal made of paper tubes, it is possible to reduce the cost. Moreover, it is possible to provide a paper container cargo pallet that has a low overall weight and is durable enough to be used for a long period of time.
