Abstract

PURPOSE:To provide a pallet for a forklift, which is excellent in the strength and mass-productivity, and low in cost. CONSTITUTION:This is a usable pallet on transferring freight by a forklift and provided with a hollow base body 1. A plurality of parallel ribs 2 are provided in the inside of this base body 1 and two fork-insertion holes 4 extending in parallel with the ribs are formed between the ribs 2 at the position near both ends of the base body 1. And ribs 6 crossing in right angles with the ribs 2 are arranged in appropriate positions in the space surrounded by the ribs 2 except the fork-insertion holes 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for a forklift used when carrying a load by a forklift and a molding method thereof.

[0002]

2. Description of the Related Art Conventionally, various types of resin pallets for forklifts have been proposed, but in terms of production efficiency and production cost,
The strength is still insufficient.

An object of the present invention is to provide a pallet for a forklift and a molding method thereof which are excellent in terms of manufacturing efficiency, manufacturing cost, strength and the like as compared with conventional products.

[0004]

The gist of the present invention will be described with reference to the accompanying drawings.

A pallet used for carrying a load by a forklift truck, in which a hollow base 1 is provided, a plurality of ribs 2 in the same direction are provided inside the base 1, and the ribs are provided at positions near both ends of the base 1. Two fork insertion holes 4 extending in the same direction as the ribs 2 are formed between two ribs, and orthogonal ribs orthogonal to the ribs 2 are formed at appropriate places in the space surrounded by the ribs 2 other than the fork insertion holes 4. The present invention relates to a pallet for a forklift, which is characterized in that 6 is provided.

A method for molding a pallet used when carrying a load by a forklift, wherein the base 1, rib 2, fork insertion hole 4 and orthogonal rib 6 are simultaneously molded by extrusion molding. The present invention relates to a characteristic method of forming a pallet for a forklift.

[0007]

Since all the ribs 2 formed on the base body 1 which is the mother body of the pallet are ribs in the same direction, the manufacturing efficiency is good and sufficient strength is exhibited.

Further, the existence of the orthogonal ribs 6 orthogonal to the ribs 2 also increases the strength in the direction orthogonal to the ribs 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The drawings illustrate an embodiment of the present invention and are described below.

A rectangular base 1 integrally provided with ribs 2 is extrusion-molded by a known extrusion molding method. The size of the fork insertion hole 4, the width of the rib 2, the number of ribs 2 and the like are appropriately designed. The resin used is P, which is a general thermoplastic resin.
P and PE are used. It should be noted that molten light metal may be used instead of resin.

At the time of this extrusion molding, the anti-slip member 3
Are molded at the same time. The anti-slip member 3 is formed of a rubber material, but any material such as EVA and elastomer may be used as long as it is a material having a bendability and an anti-slip effect.

Although the anti-slip strip 3 in the drawing is formed intermittently, it may be formed continuously.

Although the fork is often inserted into the fork insertion hole 4 to damage the ceiling wall of the fork insertion hole 4 (upper surface of the pallet), the drawings show the ceiling wall and the bottom of the fork insertion hole 4. The protection ribs 5 are formed on the wall in a continuous state in the lengthwise direction to prevent the fork insertion hole 4 from being damaged.

The orthogonal ribs 6 in the drawing are the case where the upper and lower surfaces of the pallet are pushed in and the flesh of the upper and lower surfaces are connected to form a pallet. The orthogonal ribs 6 are formed at the same time when the pallet is extruded.

Since this embodiment has the above-mentioned structure, the following operational effects are exhibited.

Since the extrusion molding method is adopted, compared with the case where the injection molding method, which is a general manufacturing method for manufacturing resin pallets, is adopted, the cost of the product is reduced by the amount that a mold or the like is unnecessary.

Further, since the extrusion molding method is adopted, the size of the fork insertion hole, the position of the ribs, and the number of ribs can be arbitrarily set easily. That is, according to the injection molding method, if the size of the fork insertion hole, the position of the ribs, and the number of ribs are changed, the die must be manufactured each time, but the extrusion molding method has such a problem. Does not happen.

Since the extrusion molding method is adopted, the length of the pallet body can be freely set by appropriately selecting the cut position of the molded product that is sequentially cured and extruded from the die.

In the product according to the present embodiment, all the ribs 2 are ribs in the same direction, so the strength is increased as compared with the case where the ribs are not regulated.

Since the anti-slip member 3 can be molded at the same time as the main body and the anti-slip member 3 is not separately provided, the manufacturing efficiency is increased accordingly.

Since the protection rib 5 exists, it is possible to prevent the ceiling wall of the fork insertion hole 4 from being damaged. The protective ribs 5 are also ribs 2 during extrusion molding of the pallet body.
Since the anti-slip member 3 is molded at the same time, the manufacturing efficiency is increased accordingly.

The existence of the orthogonal ribs 6 increases the strength of the pallet in the direction orthogonal to the ribs 2. Since the orthogonal ribs 6 are molded at the same time as the pallet body in the same manner as the protection ribs 5, the manufacturing efficiency is increased accordingly.

[0023]

As described above, the present invention provides a pallet for a forklift which is excellent in strength and mass productivity in both vertical and horizontal directions and at a low cost, and a molding method thereof.
