Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport pallet for storing and transporting products, and more particularly to a one-way transport pallet suitable for loading and transporting products for export, and a recyclable transport pallet. About pallets.

[0002]

2. Description of the Related Art Conventionally, when transporting various materials and products,
Fork list pallets are used. In these forklift pallets, a deck board is provided on the upper surface of a girder arranged at an appropriate interval, and a space surrounded by the girder and the deck board is used as a fork insertion port of the forklift. These pallets are made of wood, plastic, paper, metal or the like.

[0003] However, among these pallets,
Pallets carrying products for export are less frequently used than normal pallets after the products are transported to their destinations, and are often discarded once used. For this reason, wooden pallets that are easy to manufacture are generally used in consideration of the reduction in manufacturing cost and the strength to the product.

[Problems to be solved by the invention]

On the other hand, pallets for transporting export products include:
In many countries fumigation or chemical treatment is required for plant protection (prevention of pest infestation). Applying fumigation or chemical treatment to all of the pallets produced has been a tedious and time-consuming task for exporters, increasing costs.

In recent years, the export of timber overseas such as in Southeast Asia has been regulated due to the depletion of timber resources, and waste of natural resources has led to the destruction of the global environment and has become a major social problem. Under these circumstances, it has become increasingly difficult to obtain wood for pallets. Therefore, plastic pallets are also being used.

[0006] Most of export pallets are so-called one-way pallets which are discarded after they have been used up to a destination, and are manufactured for each product to be transported according to the size and weight of the export product. Often. Further, various physical properties such as bending strength, compressive strength, and drop strength are not required as much as those of ordinary pallets that are repeatedly used.

[0007] Conventional wooden pallets can cope with the production of many kinds in small quantities and are inexpensive. However, as described above, in addition to the problems of fumigation or chemical treatment, destruction of the natural environment, etc., recycling is also required. There is a problem that can not be. In contrast, plastic pallets can be recycled, but they can be freely resized,
There is a problem that it is not possible to cope with the production of many kinds of small quantities.

[0008] Even for wood, fumigation or chemical treatment is required mainly for softwood materials, and not for processed materials such as plywood, particle board, and laminated wood.

[0009] The present invention has been made in view of such a situation, and is applicable to the production of many kinds of small quantities, for example, the size can be appropriately changed and the strength can be changed according to the weight of the product to be transported. And it is easy to manufacture,
An object is to provide a low-cost transport pallet.

[0010]

The present invention has the following configuration to achieve the above object. That is, the pallet for transportation according to the present invention is a pallet in which a deck board is erected on a girder arranged in parallel, and a space surrounded by the girder and the deck board is a fork insertion port. And a reinforcing member fitted into a recess formed by cutting out the upper part of the spar at an appropriate interval. The relationship between the recess and the reinforcing member is H ≦ H1, preferably H <H1, where H is the depth of the recess and H1 is the height of the reinforcing member. When the height H1 of the reinforcing member is larger than the depth H of the concave portion, the reinforcing member can be reliably fixed by the pressing force of the deck board. Further, the girder and the deck board are preferably formed of a processing material such as a plywood, a particle board, and a laminated material. In addition, a cross bar orthogonal to the girder is provided at both ends of the lower surface of the girder, and the cross bar can be formed of a processed material such as a plywood, a particle board, and a laminated wood. It is preferable to provide a fork guide on the lower surface of the deck board on the side of the fork insertion port to prevent the fork from colliding with the reinforcing material. Further, the deck board may be formed by dividing into a plurality of sheets, or may be a single plate.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a preferred embodiment. The pallet 1 has the beams 3, 3 arranged in parallel at appropriate intervals, and a deck board 5 orthogonal to the beams 3, 3 is erected on the upper surface of the beams 3, 3. A reinforcing material 7 having a length substantially the same as that of the deck board 5 is interposed between the girders 3 and 3 and the deck board 5. Is provided. The pallet according to the present invention includes a waist or a bottom plate.

A space surrounded by the girders 3, 3, the deck board 5 and the cross bar 9 is formed as a fork insertion port 10,
A fork guide 11 is provided on the lower surface of the deck board 5 on the opening side of the fork insertion port 10 in order to prevent a fork from colliding with the reinforcing member 7.

In the illustrated embodiment, the lower surface of the fork guide 11 is substantially the same as the lower surface of the reinforcing member 7 and has a uniform thickness as a whole, and is formed of the same material as the deck board. If the reinforcing member 7 side is substantially the same thickness as the height of the reinforcing member 7, the lower surface of the fork is made thinner at the opening side of the fork insertion port 10 and is formed as a tapered surface or an arc-shaped surface inclined in the fork insertion direction. Is also good. Further, in the embodiment, the fork guide 11 is in contact with the reinforcing member 7, but a certain interval may be provided between the fork guide 11 and the reinforcing member 7.

[0014] As shown in FIG.
Is fitted in a concave portion 13 formed by cutting out the upper part of.
Assuming that the depth of the recess 13 is H and the height of the reinforcing member 7 is H1, H ≦ H1, and preferably H <H1. H
Is between 0 and 2 mm, preferably 0.3. ~ 1
mm. In this way, the height H1 of the reinforcing member 7 is
By making the depth greater than the depth H of the spar 3, the stiffener 7 protrudes from the upper surface of the spar 3 when assembled on a pallet.

Therefore, as shown in FIG. 4, a slight gap is formed between the upper surface of the spar 3 and the lower surface of the deck board 3 in the reinforcing member 7, and the reinforcing member 7 and the spar 3 are directly fixed. Even if not provided, the reinforcing member 7 is securely fixed only by fitting into the concave portion 13 and does not fall off. With the above structure, the pallet can be assembled by fitting the reinforcing member 7 to the inner portion 13 and placing the deck board 5 from above.
May be fixed to the digit 3 by the tucker 14 or the like. Therefore, not only can it be assembled very easily, but also it can be easily disassembled and reproduced after use.

The beam 3 can be, for example, a laminate of two 35 mm-thick particle boards and processed into a 70 mm square bar. The deck board 5 and the crosspiece 9 are, for example, 9 mm-thick plywood. One processed to a width of 150 mm can be used. The reinforcing member 7 has, for example, a width of 22 mm, a height of 10 mm, and a thickness of 1.2 m.
m square pipes can be used. Deck board 5
To assemble the jump rung 9
In addition to using 4, a nail may be used to fix the beam 3.

In the above configuration, the girder 3, deck board 5
The material of the cross bar 9 may be a processed material such as plywood, particle board, glued laminated wood or the like which is not a target of fumigation or chemical treatment. In particular, a plywood can be used for the deck board 5 and the cross bar 9. In addition, the dimensions of the pallet 1 may be appropriately determined according to the size and weight of the product to be placed. In particular, according to the present invention, since the weight is not applied only by the deck board 5 but is applied by the reinforcing member 7, the reinforcing member 7 having a large diameter is used even with the same pallet size. It can be a high strength pallet.

Further, the diameter of the reinforcing member 7 in a portion (for example, the center portion) which receives a large load is made larger than that of the reinforcing member at the end portion, or the interval between the reinforcing members 7 (for example, the reinforcing portion in the center portion). By reducing the distance between the members, it is possible to cope with partial reinforcement depending on the load. Thus, an efficient pallet corresponding to each load to be transported can be obtained, and a pallet of appropriate quality can be obtained.

The deck board 5 is not divided into a plurality of pieces as in the illustrated embodiment, but may be a single board. In this way, when the deck board 5 is made of a single plate and covers the entirety, it is possible to prevent the protrusions and corners of the load from entering the gaps. The load can be easily moved.

FIG. 5 shows an example of a method of fixing a load. A wooden box 15 is placed on the load and held. The reinforcing material 7 is inserted from the lower surface of the deck board 5, that is, from the fork insertion port 10. A supporting member 19 is connected to a locking member 17 abutting on the lower surface of the pallet, a fastening member 20 is inserted over an upper end of the supporting member 19, and a wooden box 15 is integrally fixed to the pallet 1. The fastening member 20 can be configured to fasten the wooden box 15 with a nut 21 screwed to the upper end of the support member 19.

In the above, the support member 19 and the fastening member 20
May be replaced with a strap made of a plastic sheet or a steel sheet. The method of fixing the load is
Of course, the present invention is not limited to the above embodiment.

[0022]

As is apparent from the above description, the transport pallet according to the present invention has the following effects. (1) Since it is made of a processing material such as a plywood, a particle board, and a laminated material, no fumigation or chemical treatment is required, and the cost can be reduced as compared with a conventional wooden pallet. (2) Pallets of any size can be obtained by changing the length of the girder and / or deck board, and by changing the spacing or diameter of the reinforcing material, The strength can be changed in whole or in part according to the weight. (3) Since the dimensions can be arbitrarily changed, it is possible to provide a low-cost transport pallet that can cope with the production of many kinds of small quantities and is easy to produce. (4) It is easy to assemble and disassemble, and can be reproduced because it is made of a processing material such as plywood, particle board, and glued laminated wood, and is suitable as a one-way pallet.
