Description

Palette using a paper

The present invention relates to a pallet, and more particularly, to a pallet using paper which is light, contributes to prevention of environmental pollution through recycling, and is inexpensively produced.

Pallets are typically used for storage, shipping and transport of goods and are molded from wood and plastics. Since they have sufficient rigidity, they have excellent load-bearing capacity, but have a problem in that they are expensive in case of export transportation, which is difficult to recover due to their high unit cost. As a result, disposal is becoming a serious threat to environmental pollution. In addition, the wooden pallet has a problem in that the moisture moisture content is high to provide an environment in which bacteria (fungus) can easily grow.

In recent years, pallets made of paper such as cardboard and paper, which are inexpensive, have appeared. These paper pallets are advantageous in cost reduction due to the low cost of raw materials, and can be easily assembled without using nails or fastening means, thereby reducing the production time without the need for subsidiary materials. In addition, these paper pallets are superior in vibration and vibration resistance compared to wood or plastic and less damage to pests than wood. As it is recycled, it is economical and helps to prevent environmental pollution.

However, the problem of such a paper pallet has a problem that insufficient rigidity cannot be exhibited. That is, the legs attached between the upper panel and the lower panel are mostly bonded by the adhesive and the nail of the "c" shape, but the contact area is small and the adhesive strength is weak. Therefore, the load capacity acting vertically is good but is weak to torsion and impact, and when the forklift is in contact with the leg due to malfunction of the forklift, the leg is broken or twisted and cannot be used, and the life is shortened. In addition, the process is complicated and mass production is difficult as attaching a reinforcing frame or bending for reinforcing to increase the strength.

The present invention is to overcome the above-mentioned conventional problems, the object of the present invention is to increase the strength and durability by increasing the adhesive strength, to provide a pallet using paper that can reduce the production process and mass production with a simple structure.

In order to achieve the above object, the present invention has an upper panel 10 having an auxiliary plate attached to a lower portion of the upper plate, and a flange 22 attached to the bottom of the upper panel 10 and protruding outwardly on the upper plate. Consists of the legs 20, the reinforcing frame 18 is attached along the outer side surface of the upper panel 10 and the flange formed on the leg, characterized in that the branch pipe 28 is selectively installed into the leg It is done.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of the disassembled pallet using paper according to the present invention, Figure 2 shows a central cross section of the pallet assembly state using a paper according to the present invention. According to the drawings, the pallet 100 using the present invention paper is attached to the upper panel 10 or lower panel 10a coupled with predetermined auxiliary plates 14 and attached to the lower portion of the upper panel or between the upper panel and the lower panel. It consists of a leg 20 attached to.

The above is described in more detail as follows.

First, the upper panel 10 and the lower panel 10a have a structure corresponding to each other, but install a leg 20 in the center, but also constitute a pallet having a structure without the lower panel 10a.

At this time, the upper panel 10 is a top plate 10 made of a laminated board and the auxiliary plate 14 made of a multi-layer laminated board attached to the bottom surface is bonded with an adhesive. In addition, the lower panel 10a also has a structure in which the lower plate 10 made of a lamination board and the auxiliary plate 14 made of a multi-layer lamination board attached to the upper surface thereof are bonded to each other while being opposed to each other.

In addition, the legs 20 installed on the bottom surface of the upper panel 10 or between the upper panel 10 and the lower panel 10a are attached to respective corners and intermediate points of the upper panel or the lower panel in a square or circular shape. Is formed. The legs 20 constitute flanges 22 and 24 that extend outwardly at the top or the bottom. Accordingly, the upper surface of the upper flange 22 is attached to the bottom surface of the upper panel 10 by an adhesive, and the lower surface of the lower flange 24 is attached to the upper surface of the lower panel 10a by an adhesive.

Meanwhile, the concave groove 16 is formed at a position at which the legs are attached to the inner surfaces of the upper panel 10 and the lower panel 10a, and the branch pipe 28 is inserted into the leg 20. The upper end and the lower end of the 28 may be inserted into the concave groove 16 so as to reinforce the leg or perform the leg role only with the branch pipe 28.

In addition, the flanges 22 and 24 and the auxiliary plate 14 may be nailed in the "c" shape after adhesion by an adhesive to increase the adhesive strength.

Next, the reinforcing frame 18 of the "L" shape is bonded to the outer surface of the joint portion of the panel (10, 10a) and the legs to reinforce the adhesive force. In other words, the reinforcing frame 18 is vertically bent and is attached to overlap the outer surface to the bottom surface of the flange formed on the side circumference and the leg of the upper panel 10. In addition, the reinforcing frame 18a is attached along the periphery of the lower panel 10a which is symmetrical with the upper panel 10.

The pallet using the present invention paper configured as described above is completed by attaching a leg 20 integrally formed with an adhesive to an upper panel or a lower panel and attaching a reinforcing frame. An embodiment is shown.

3 is a state in which only the branch pipe 28 is installed without the leg 20, and the upper end of the branch pipe is inserted into the recess groove of the upper panel 10 and the lower portion of the branch pipe is inserted into the recess groove of the lower panel 10a. It is firmly fixed by Therefore, it has sufficient strength even without the legs 20 and the reinforcing frames 18 and 18a formed to the outside.

4 is a state in which only the leg 20 is installed without the branch pipe 28 described above, and may have a large contact area of the flanges 22 and 24 and a large strength as a reinforcing frame.

Therefore, the structure of the leg 20 may be changed to obtain the required strength while reducing the manufacturing cost when assembling the pallet 100.

As described above, the pallet using paper according to the present invention is to reduce the manufacturing process with a simple configuration and to be mass-produced, and to increase the bonding area by the flange structure of the legs and the uneven type assembly method. To increase. Therefore, the load capacity is increased, not easily broken, and the durability is increased.
