[Problems to be solved by the invention]
The corrugated cardboard pallet described in Patent Document 2 is designed to form the product bearing surface only from the upper end surface of each girder (horizontal girder), and not only requires a large number of girder materials, Since such a large number of girders have a structure like an integrally molded product in which a few gaps are arranged in parallel, there is a problem that material is wasted.
The pallet for conveyance described in Patent Document 3 can solve the problem caused by Patent Document 2 by combining a plurality of horizontal beams and vertical beams, but a space portion is formed between the vertical beams and between the horizontal beams. Therefore, the supporting strength of this part is weakened, and when a large number of products such as acrylic curved plates attached to the front of a large screen LCD TV are stacked, the load distribution is uneven and the product is wavy ( There is a possibility that a wavy deformation may occur.
[0007]
The present invention has been made in view of such conventional circumstances, and the object of the present invention is to swell when the load distribution is uneven, such as an acrylic curved plate mounted on the front surface of a large-screen liquid crystal TV. A paper pallet for transporting products that are likely to be deformed in a large number of products such as the curved plate in a state where the load is uniformly distributed so that the wavy deformation does not occur. It is an object of the present invention to provide a new paper pallet that can be stacked and conveyed and can be formed without waste of material.
[0008]

[0012]
According to a third aspect of the present invention, the outer case (7) is fixed to an upper surface of a lower pallet (b) having a fork insertion opening (8) on a side peripheral wall.
[0013]
When formed in this manner, the paper pallet is integrally provided with the lower pallet (b) having the fork insertion opening (8), so that the transport work can be easily performed using the forklift.

The X-shaped crosspiece 5 is combined in an outer case 7 having a size of about 900 mm × 700 mm to form a pallet main body a, and the upper surface of the pallet main body a has the same size as the outer case 7 and is curved. The upper surface plate 6 that is curved with the same curvature as the plate 100 is fixed, and the outer case 7 is further placed on the deck board 9 of the lower pallet b, and the required portions of these components are fixed with a desired adhesive. A paper pallet A was prepared.
On the upper surface plate 6 of the paper pallet A, about 20 acrylic curved plates 100 to be mounted on the front surface of the large-screen liquid crystal TV were stacked and allowed to stand for a predetermined time. Without deformation, the forklift could be used to transport in a stable state.
[0031]
The embodiment of the present invention has been described above with reference to the drawings. However, the configuration and application of the paper pallet according to the present invention are not limited to the illustrated examples, and are described in the claims. It goes without saying that various modifications are possible within the scope of the technical idea.
[0032]
【The invention's effect】
As described above, the present invention is a paper pallet made of paperboard such as corrugated board, and therefore has lower material costs, better manufacturability, and lighter weight than a pallet made of wood or synthetic resin. It is easy to handle and also suitable for recyclability.
In addition, the space formed between the left and right and center vertical beams and a plurality of horizontal beams is loaded with an X-shaped beam so that the load on the product (conveyed object) is evenly distributed. Therefore, the load applied to the product can be uniformly dispersed and supported while using the paper material efficiently. Therefore, products such as an acrylic curved plate mounted on the front of a large-screen liquid crystal TV that are prone to undulating deformation when the load distribution is uneven are stacked without causing such deformation. It was possible to provide a new paper pallet that can be transported and can be manufactured at low cost without wasting material.
