Abstract

[PROBLEMS] Conventional girder of corrugated cardboard pallet is made with emphasis on load-bearing, and therefore has high strength, but has problems such as low adhesive strength to a top plate and a bottom plate and difficulty in mounting method. Was.
According to the present invention, a flat paper tube girder having a flat surface is formed by cutting the upper and lower two portions of the circumferential surface of a cylindrical paper tube, and this is installed horizontally. By bonding the top plate and the bottom plate, we succeeded in making a strong cardboard pallet with strong adhesion.

Description

Detailed description of the invention

The invention relates to the field of cardboard pallets.

Conventionally, the girder used for corrugated cardboard pallets is often a laminated girder made of multiple layers of corrugated cardboard, or one obtained by cutting a paper tube into a circle, and vertically standing and bonding it to a top plate or a bottom plate. I have.

Issues that the device is trying to solve

Although these laminated girders and paper tube girders have high strength, there are problems such as low adhesive strength to the top plate and bottom plate of the corrugated cardboard pallet, difficulty in mounting methods, and the problem of high price. .

Means for solving the problem

As a method of solving these problems, a flat paper tube having a flat surface is formed by cutting the upper and lower portions of the circumference of a cylindrical paper tube, and the flat paper tube is installed horizontally as a girder. By bonding the top plate and the bottom plate to each other, we succeeded in obtaining a strong adhesive force.

Inventive embodiment

Hereinafter, a basic form of the present invention will be described.
FIG. 2 shows a two-sided flat paper tube having a flat surface A by cutting the upper and lower two portions of the circumferential surface of a cylindrical paper tube having a wall thickness of 10 cm to 30 cm into approximately 10 mm in thickness. The girder 3 is made, and nine or so girders are usually set horizontally. The top plate 1 and the bottom plate 2 of the corrugated cardboard are stuck on the upper and lower sides to complete the flat paper tube girder cardboard pallet FIG.

FIG. 3 shows one flat paper tube girder 4 having one cut flat surface A. Usually, this flat paper tube girder is made as long as 90 cm to 110 cm in length, and is used for a two-way pallet or a skit pallet shown in FIG.

FIG. 5 shows the four flat paper tube girder 5 in which the flat surface A is formed on the side surface in addition to the two cut upper and lower flat surfaces A.

FIG. 6 shows a parallel girder 6 in which two quadrangular paper tubes are arranged. Usually, this girder is used as one girder by arranging two pallets in parallel when the pallet load is large and heavy. When arranging two, it is easier to fix if the flat surface A is on the side surface.

FIG. 7 shows an embodiment of a pallet using nine parallel girders 6.

The effect of the invention

The greatest effect of the flat paper tube girder pallet according to the present invention lies in the reuse of the paper tube. Currently, most of the paper tubes used for printing roll paper are treated as industrial waste.However, the paper tubes are hard and durable, so it takes time to process them, and the volume is very large. Processing costs are also expensive.
The present invention is intended to provide a cheap and robust pallet while reducing the amount of waste by reusing the large amount of paper tubes as a pallet beam by processing it a little.
