Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin pallet in which synthetic resin pallet molding members having a plurality of girders separated by a predetermined distance from each other are bonded to each other with the girders.

[0002]

2. Description of the Related Art Conventionally, when transporting various articles, a method has been used in which the articles are stacked on a pallet, and the articles are lifted and carried together with the pallet using a forklift. There are various types of pallets for loading and transporting such articles. For example, there are wooden pallets, metal pallets, and synthetic resin pallets depending on the material. Wooden pallets have drawbacks such as unstable supply due to tight wood resources, poor durability and chemical resistance, and complicated manufacturing. Metal pallets are disadvantageous in that they are expensive, heavy and easily corroded. Therefore, in recent years, synthetic resin pallets have been increasingly used.

[0003] A synthetic resin pallet is generally formed by molding a synthetic resin pallet molding member having a plurality of girders separated by a predetermined distance from each other, and bonding these pallet molding members to each other with the girders. And a fork insertion hole for inserting a fork from a space between the adjacent girders is formed. There is no problem as long as the fork is inserted straight into the fork insertion slot, but if the fork enters at an offset with respect to the fork insertion port or enters at an angle, the fork is inserted into the fork insertion port. Accidentally colliding with nearby girders and possibly damaging the pallet.

In order to avoid this, conventionally, a method of increasing the thickness of the pallet from 4 to 5 mm to 6 to 7 mm, a method of reducing the thickness of the pallet to 10 mm by low foaming, and a method of reinforcing There is a method of providing excessive ribs. Further, as a conventional example of providing a reinforcing rib, a structure in which the reinforcing rib is formed so as to protrude inward from a corner portion inside the spar,
A structure in which reinforcing ribs with complicated shapes are provided inside the girders
No. 51-108438, JP-A-50-117145, JP-B-60-55374)
There is.

[0005]

In the conventional example in which the thickness of the pallet is increased, there is a disadvantage that the weight of the pallet itself increases. Even in the conventional example where the thickness of the pallet is increased by low foaming, the weight increase of the pallet is large, the molding time for cooling the foam is prolonged, and the cost of the foaming agent is increased. The inconvenience of doing so occurs.

Further, in the conventional example having a simple structure in which the reinforcing ribs are formed so as to project toward the corners inside the spar, although the weight of the pallet does not increase much, the reinforcement with the reinforcing ribs is not sufficient. There is an inconvenience that it is generated from the bonded portion at the end of the rib. Further, in the conventional example using the reinforcing ribs having a complicated shape shown in JP-A-50-117145 and JP-B-60-55374, not only does the weight of the pallet increase,
In order to avoid complication of the mold for injection molding, the height of the reinforcing ribs must be reduced, and the strength of the pallet cannot be sufficiently increased.

In other words, in order to increase the strength of the pallet, it is preferable that the height of the reinforcing ribs be approximately the same as the height of the adhesive surface of the spar. However, when injection molding a pallet molding member, the molding cycle is shortened. This is indispensable, and therefore, a plurality of cooling tubes must be installed in the injection mold. However, if the shape of the reinforcing ribs is complicated, if the height of the reinforcing ribs is the same as the height of the adhesive surface of the girder, there is no room for cooling pipes. It is formed low. Further, in the conventional example disclosed in Japanese Patent Application Laid-Open No. 51-108438, the position where the reinforcing rib is provided is limited, and there is a disadvantage that the fork inserted from a specific direction cannot have sufficient strength. .

An object of the present invention is to provide a lightweight and inexpensive synthetic resin pallet which can maintain sufficient strength without being damaged even when a fork is erroneously inserted and can be manufactured with high productivity. It is in.

[0009]

Therefore, the present invention provides reinforcing ribs which form a substantially box-shaped space in a direction in which a fork is inserted into a spar and in a direction perpendicular to this direction. The above-mentioned object is achieved by bonding the tips of the pallet reinforcing ribs to each other. Specifically, the synthetic resin pallet of the present invention is such that synthetic resin pallet molding members having a plurality of girders separated from each other by a predetermined distance are bonded to each other by girders, and from the space between girders adjacent to each other. In a synthetic resin pallet in which a fork insertion hole for inserting a fork is formed, a predetermined width and depth are set in a direction in which the fork is inserted into a girder adjacent to the fork insertion hole and in a direction orthogonal to this direction. Reinforcement ribs each forming a substantially box-shaped space having are provided on each pallet molding member, and the tip ends of the reinforcement ribs provided opposite to each other on these pallet molding members are bonded to each other. I do.

According to the present invention having this configuration, a plurality of pallet forming members are formed in a state where the reinforcing ribs are provided by injection molding, press forming, or other forming methods, and these pallet forming members are bonded to each other to be synthesized. Manufactures resin pallets. In this synthetic resin pallet, since the reinforcing ribs have a simple shape in which a substantially box-shaped space is formed inside the girders, the space defined by the reinforcing ribs is enlarged to secure a space for cooling pipe arrangement. Therefore, the height of the reinforcing rib can be increased. Therefore, the reinforcing ribs provided on each pallet forming member are bonded to each other to increase the strength of the beam.

In addition, since a substantially box-shaped space having a predetermined width and depth is formed not only in the direction in which the fork is inserted by the reinforcing ribs but also in a direction perpendicular to this direction, the fork can be inserted from any direction. When entering the entrance, even if the beam near the fork insertion port erroneously collides, the beam is not damaged, and the pallet strength can be increased from this point as well. Further, since it is not necessary to increase the thickness of the pallet itself, it is not necessary to increase the weight of the pallet. In addition, since there is no need to produce the foam by a low foam injection method, there is no need to take molding time for cooling the foam, and there is no cost for a foaming agent, so that the total cost does not increase.

Here, in the present invention, a structure may be adopted in which a part of the reinforcing rib is a corner reinforcing rib which is continuous with a corner of the beam. With this structure, even if the fork collides obliquely with the corner of the girder, the force is transmitted to the reinforcing ribs in the longitudinal direction instead of from the side, and the girder can be reliably prevented from being damaged. it can. Further, the depth dimension of the substantially box-shaped space formed by the reinforcing rib is set to 30 to 4
The width may be set to 0 mm and the width may be set to 80 to 160 mm. If the depth of the substantially box-shaped space is less than 30 mm or the width thereof is less than 80 mm, the space for disposing the cooling pipe becomes small, and the height of the reinforcing rib cannot be increased. On the other hand, if the depth dimension is set to a value exceeding 40 mm or the width dimension is set to a value exceeding 160 mm, the strength of the pallet itself is reduced.

Further, in the present invention, the fork insertion port may be provided on two sides, and the fork may be inserted from two directions. In this configuration, the girders can be arranged along the remaining side surfaces where the fork insertion opening is not formed, so that the area where the girders are bonded to each other increases, and the strength of the synthetic resin pallet increases.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. Here, in each embodiment, the same components are denoted by the same reference numerals, and description thereof will be omitted or simplified.
1 to 5 show a first embodiment of the present invention. FIG. 1 is a plan view showing a pallet molding member of the synthetic resin pallet according to the first embodiment, and FIG. 2 is a front view of the synthetic resin pallet.

In these figures, a synthetic resin pallet according to the first embodiment is composed of a synthetic resin pallet molding member 3 having three girders 2 spaced apart from each other by a predetermined distance on a plate 1, A pallet molding member 5 made of synthetic resin having three separated girders 2 is bonded to each other with girders 2, so that a fork of a forklift (not shown) is inserted from a space between the girders 2 adjacent to each other. Is a two-way pallet in which two fork insertion ports 6 are formed on two opposite sides.

This synthetic resin pallet is a single-sided pallet on which articles are loaded only on the upper surface of the plate material 4. Therefore, a fork is inserted only near the fork insertion port 6 of the upper pallet molding member 5. A guide surface 5A for guiding to the mouth 6 is formed. In the first embodiment,
It is also possible to apply the present invention to a synthetic resin pallet in which the plate members 4 are bonded to each other with the girders 2 and articles can be stacked on both sides.

These pallet molding members 3 and 5 are made of polypropylene, propylene-ethylene block copolymer,
Polyolefins such as high-density polyethylene, or polystyrene, rubber-modified polystyrene, acrylonitrile-styrene copolymer, acrylonitrile-styrene-butadiene copolymer, polyamide, formed from synthetic resins such as polyvinyl chloride, these synthetic resins , If necessary, elastomers, reinforcing agents such as glass fiber, curk,
A filler such as calcium carbonate, or a pigment, a stabilizer or the like is added. The pallet molding members 3 and 5 are integrally formed by injection molding, injection compression molding, or press molding, respectively, and their adhesion is generally welded by heat, but other methods such as adhesives are used. May be.

The plate material 1 of the pallet molding member 3 has a plane formed in a substantially square shape having a width L as shown in FIG.
A plurality of main ribs (not shown) are formed on a surface facing the pallet forming member 5. In the drawing, a circular portion indicated by reference numeral 7 is a hole for mounting anti-slip rubber. In the first embodiment, the width L is determined as appropriate, but for a pallet that is normally used, L is 800 to 1500 mm. In addition,
In the first embodiment, the planar shape of the pallet molding members 3 and 5 may be a shape other than a square, for example, a rectangle.

Two girders 2 of the pallet forming member 3 are arranged along one side of the plate 1 facing each other, and the other one is arranged at an intermediate position between these two girders 2. Are parallel to each other. The inside of these girders 2 is composed of a main portion 2A formed at the center portion and reinforcing portions 2B provided at both ends of the main portion 2A, and the outer portions of the main portion 2A and the reinforcing portion 2B are formed. A wall 8 is provided. At the four corners of the spar 2, the wall portion 8 is formed to be curved.

The main portion 2A has a structure in which grid-like main ribs 9 are arranged between the wall portions 8 facing each other.
Has a structure in which reinforcing ribs 10 forming a substantially box-shaped space 10F are arranged between the wall portions 8 in a total of three directions of a direction P in which the fork is inserted and a direction Q orthogonal to the direction P. The main rib 9 is composed of a first main rib 9A arranged along the longitudinal direction of the spar 2 and a plurality of second main ribs 9B arranged orthogonally to the first main rib 9A. A substantially box-shaped hollow portion is formed in the ribs 9A and 9B and the wall portion 8.

As shown in FIG. 3 in an enlarged manner, the reinforcing rib 10 is formed continuously with the first main rib 9A and has a front end in contact with the wall portion 8A. A second reinforcing rib 10B disposed parallel to the second main rib 9B at the base end of the first reinforcing rib 10A and having both ends in contact with the wall portion 8
At the intermediate position of the second reinforcing rib 10B.
Third reinforcing rib 1 arranged in parallel with reinforcing rib 10A

The second main ribs 9A and 9B and the wall 8 have the same height. Further, the fifth reinforcing rib 10E constitutes a corner reinforcing rib continuous with the corner of the spar 2.

In FIG. 4 showing a plane cross section of the reinforcing rib 10, four substantially box-shaped spaces 10F are formed from the first to fifth reinforcing ribs 10A to 10E and the wall portion 8, and these substantially box-shaped spaces are formed. The depth dimension U of the space 10F is 30 to 40 mm, and the width dimension V is 80 to 160 mm. If the depth dimension U is less than 30 mm or the width dimension V is less than 80 mm, the space for arranging the cooling pipe arranged in a mold such as injection molding becomes small, and the height dimension of the reinforcing rib 10 is reduced. It cannot be at the same height as the wall 8. On the other hand, when the depth dimension U is set to a value exceeding 40 mm or the width dimension V is set to a value exceeding 160 mm, in general, the fork cannot withstand a load and accidentally collides with the fork. (For example, collision speed 0.8Km / h, vehicle weight 3.7
5t).

The specific numerical values of these dimensions U and V are determined in relation to numerical values such as the width dimension W of the spar 2 and the length dimension S of the reinforcing portion 2B. For example, W = 195 mm, S = 137.5
In the case of mm, the depth dimension U is 30 mm and the width dimension V is 97.5 to 107.5 mm. The first to fifth reinforcing ribs 10A to 10E, the first to second main ribs 9A,

In the above, the lower pallet molding member 3
However, the pallet forming member 5 arranged on the pallet forming member 3 has the same structure as the pallet forming member 3 in the main part. That is, the plate member 4 of the pallet forming member 5 has a plurality of main ribs (not shown) formed on the surface facing the pallet forming member 3 like the plate member 1. As shown in FIG. 5, a main part 2A composed of a main rib 9, a reinforcing part 2B provided at both ends (only one end is shown in FIG. 5) of the main part 2A, a main part 2A and the reinforcing part And a wall 8 surrounding the periphery of the portion 2B. These reinforcing ribs 1

0 are bonded (welded) to each other, and the bonding surface M is formed parallel to the plane of the plate 1 and the plate 4.

Therefore, in the first embodiment, the synthetic resin pallet molding members 3 and 5 having three girders 2 spaced apart from each other by a predetermined distance are bonded to each other by the girders 2 and the adjacent girders 2 are formed. A fork insertion hole 6 is formed from the space between the fork insertion holes 6, and a predetermined width U and a predetermined width U are set in a direction P in which the fork is inserted into the inside of the spar 2 adjacent to the fork insertion hole 6 and a direction Q orthogonal to the direction P. Substantially box-shaped space 1 having V
OF is provided on each of the pallet molding members 3 and 5, and these pallet molding members 3 and 5 are provided.
Since the reinforcing ribs 10 are provided such that the distal ends of the reinforcing ribs 10 are bonded to each other, the reinforcing ribs 10 have a simple shape in which a substantially box-shaped space 10F is formed inside the spar 2. The space defined by the reinforcing ribs 10 can be enlarged to secure a space for arranging the cooling pipes, and the height of the reinforcing ribs 10 can be increased by the wall portions 8 of the beam 2 and the main ribs 9.
Can be as high as the height of Therefore, the reinforcing ribs 10 provided on each of the pallet molding members 3 and 5 are bonded to each other, so that the strength of the beam 2 can be increased.

In addition, not only in the direction P in which the fork is inserted by the reinforcing ribs 10 but also in the direction Q perpendicular to this direction, a substantially box-shaped space 10F having a predetermined width and depth.
Is formed, even if the fork enters the fork insertion port 6 from any direction and collides with the spar 2 near the fork insertion port 6 by mistake, the spar 2 is not damaged. further,
Since it is not necessary to increase the thickness of the pallet itself, there is no need to increase the weight of the pallet, and furthermore, since there is no need to manufacture the pallet by a low foam injection method, a molding time for cooling the foam is taken. There is no need to do so, and there is no foaming agent cost, so that the total cost does not increase.

In the first embodiment, the reinforcing rib 1
0, some of the reinforcing ribs 10E are corner reinforcing ribs continuous with the corners of the spar 2, so that even if the fork collides obliquely with the corners of the spar 2,
The force will be transmitted to E in the longitudinal direction, not from the side,
The breakage of the girder 2 can be reliably prevented. further,
Since the fork insertion port 6 of the synthetic resin pallet is formed on two sides and the fork can be inserted from two directions, the spar is formed along the remaining side where the fork insertion port 6 is not formed. 2 can be arranged, so that the area where the girders 2 provided on the upper and lower pallet molding members 3 and 5 are bonded to each other becomes large, and the strength of the synthetic resin pallet becomes large.

Further, since the main portion 2A of the beam 2 is constituted by the main rib 9, the weight of the synthetic resin pallet can be reduced, and the strength of the main portion 2A of the beam 2 can be increased.
Further, since ribs (not shown) are provided on the plate material 1 and the plate material 4, the weight of the synthetic resin pallet can be reduced, and the strength of the plate material 1 and the plate material 4 can be increased. Furthermore, since the wall portion 8 is curved at the four corners of the spar 2, the fork can be smoothly guided to the fork insertion port 6, and the spar 2 can be prevented from being damaged.
