Abstract

<P>PROBLEM TO BE SOLVED: To provide a paper tube pallet which is easily performing mechanization and mass production by forming an assembly of members of simple shapes, capable of using a large amount of paper tubes disposed by a printing company as industrial waste, reduced in cost and adaptable to the environment. <P>SOLUTION: A corrugated fiberboard pallet is formed by affixing a plurality of semi-circular and long paper tubes 3 on a corrugated fiberboard sheet of a deck board 1 and a bottom board 2, and a considerably strong board can be formed. In addition, two of these boards are affixed vertically so that directions of the paper tubes are orthogonal to each other, and an ideal pallet having high strength in both right and left directions can be formed. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention belongs to the field of cardboard pallets.

The deck board and bottom board of cardboard pallets currently on the market are mainly made by bonding reinforced cardboard. In addition, a wide variety of girders such as those obtained by cutting a laminated corrugated cardboard into a prismatic shape, or a corrugated cardboard sheet assembled in a box shape, are made.

Corrugated cardboard pallets that are currently on the market have already been developed and used for the strength of the girders enough to withstand the weight of the load. However, the deck board and the bottom board have not yet been developed with sufficient strength, especially in the case of products with bags that have a heavy load and fluid shape, or products with flexible containers, etc. The current situation is that the middle part of the girder cannot bear the weight and still relies on wooden and plastic pallets.

In the present invention, a long girder having a semicircular shape made by cutting a cylindrical paper tube in half is formed on a deck board and a tom board having a problem in strength, and a plurality of them are arranged in parallel on a cardboard sheet, We have succeeded in making a strong board by bonding the cut surface of the tube and the cardboard sheet. After combining these two boards up and down so that the directions of the paper tubes are perpendicular to each other, they succeeded in making a new pallet in which the deck board and bottom board are integrated by firmly bonding them together.

Since the pallet according to the present invention is an assembly of members having a simple shape, it is easy to be mechanized and mass-produced, and paper tubes that are disposed of as industrial waste by printing companies in large quantities should be used. It can be said that the product is suitable for the environment.

The paper tube which is the main constituent material of the pallet of the present invention is a paper tube of roll paper which is used in large quantities by a printing company and is disposed of as industrial waste. This thick and strong paper tube was cut in half and bonded to a cardboard sheet as a girder material to make a board that resists bending stress, making an ideal pallet.

The board is made by arranging a plurality of long semicircular paper tubes 3 in parallel on the cardboard sheet 1 and firmly bonding the cut surface of the paper tube and the cardboard.

Two boards are set as one set, and the directions of each paper tube are perpendicular to each other.

Usually, a paper tube has a diameter of 105 to 110 mm and a wall thickness of about 15 mm. If this paper tube is cut in half, it is possible to make a girder having a height of about 55 mm. When a cardboard sheet is pasted on this girder, a board with a thickness of 60 mm can be quickly made, and when two boards are joined together, a pallet with a height of 120 mm can be made.

The bottom board constituting the lower layer has a height of 60 mm, and a normal forklift can be used, but a hand fork requires a height of 90 mm. In this case, instead of the semicircular paper tube, a flat paper tube 4 having a height of 90 mm is used, or a laminated girder 5 in which laminated cardboard is cut into a prismatic shape is used. When using either girder, it is better to paste the bottom plate 6 under the girder.

Not only the bottom board 2 but also the deck board 1 can be used to make a four-way pallet that can be used from either direction if the forklift claw can be inserted into the gap between the girders.

The deck board 1 is in a state in which a semicircular paper tube is bonded to the cardboard, but the cardboard on the upper surface of the bottom board 2 is bonded to the lower surface. You can make a stress-resistant deck board.

Industrial applicability

The biggest feature of this pallet is the deck board that resists bending stress. This means that a path that can be used as a pallet for heavy objects, which could only be used with wooden pallets and plastic pallets, has been opened up. Therefore, it can be widely used in the pallet market, which currently has a 70-80% share of the pallet market.

It is a whole view of a pallet. It is the figure which used the flat paper tube for the lower layer part. It is the figure which used the lamination girder for the lower layer part.
