In particular, when conveying foods, medicine, medicines, cosmetics, and the like, this demand becomes stronger. In addition, a pallet for cargo handling has been used for loading and unloading and transporting cargo with a forklift. And as the conditions that the cargo pallet should have,
Since it is necessary to reduce the weight of the cargo handling pallet itself, conventionally, as shown in FIG. 9, a cargo handling pallet including a top plate 3 on which a heavy object is placed and a columnar material 5 supporting the same is used. Was used. However, in such a cargo handling pallet, although the weight of the cargo handling pallet itself can be reduced, when a heavy object is placed, the load is applied to the columnar material 5 occupying a relatively narrow area. There was a problem in terms of load bearing. Therefore, as shown in FIG. 10, a pallet for cargo handling, which has improved load-bearing capacity and is suitable for carrying heavy loads, is provided with a strip-shaped stringer 2 instead of the columnar member 5 (see FIG. 10). Reference is made to Utility Model Registration No. 2585858). However, in the case of such a cargo handling pallet, in order to improve the load resistance, since the side wall plate constituting the stringer is a simple flat plate having no hole, when inserting the fork, the two-way There is a problem that the direction of use of the pallet for cargo handling is limited because the pallet can only be inserted from the pallet.

[0004] The present invention has been made in view of the above viewpoints, and various types of luggage (goods) are provided in a cleaner and safer state.
It is another object of the present invention to provide a cargo handling pallet capable of transporting a forklift and a cargo handling pallet that is lightweight, has excellent load resistance, and can easily insert a fork of a forklift from four directions.

Then, the distance between the upper surface of the upper partition plate 211 and the upper inner wall surface of each girder 2 and the lower partition plate 212
And the lower inner wall surface of each girder 2 are made equal in distance.

In this embodiment, in order to reduce the weight of the pallet 1, each beam 2 is made of a thin hollow member, but the upper partition plate 211 and the lower partition plate 2
Since 12 functions as a reinforcing rib, the rigidity of each girder 2 is sufficient. However, the number of the partition plates 211 and 212 provided in the girder 2 is not particularly limited.
May not include the partition plates 211 and 212.

Further, as shown in FIG.
The left and right side wall plates 213a and 213b have
4, 214 are provided two each. Note that, for each girder 2, the distance between one insertion opening 214 and one end of the girder 2 along the longitudinal direction, and the distance between the other insertion opening 214 and the longitudinal direction of each girder 2. The distance to the end is equal. Also, in each of the beam members 2, each of the insertion openings 214, 214
Are provided at the same position. Therefore, three girder members 2
Can be aligned along the lateral direction of the girder material 2.

The top plate portion B constitutes a mounting portion T on which luggage is mounted. As shown in FIG.
Are arranged along the lateral direction of the beam 2.
This beam member 3 is also manufactured by extrusion molding, and as shown in FIG. 6A, is formed using a hollow member having a substantially trapezoidal cross section. Also, on the surface of this beam material 3,
A ridge M for non-slip is provided along the longitudinal direction,
Both corners on the front side are chamfered.

Further, two partition plates 311 and 312 are respectively extended substantially vertically between the upper and lower inner wall surfaces of each beam member 3, and the internal space of each beam member 3 is divided into three along the width direction. ing. In the present embodiment, in order to reduce the weight of the pallet 1, each beam member 3 is formed using a thin hollow member, but the two partition plates 311 and 312 function as ribs for reinforcement. Therefore, the rigidity of each beam member 3 is sufficient. However, the number of the partition plates 311 and 312 provided in the beam member 3 is not particularly limited, and the beam member 3 may not include the partition plates 311 and 312.

In each of the beam members 3, a specially-shaped luggage (a specially shaped object such as a round shape) is inserted between two adjacent beam members (3a and 3b, 3c and 3d) above the insertion opening 214. ) Are mounted on the mounting plate 6 for fixing a mounting plate (see FIGS. 1 and 3). The number of the mounting plates 6 and the arrangement and fixing positions are not particularly limited. However, it is preferable to provide two or four mounting plates 6 so as to be point-symmetric with respect to the center point of the pallet 1.

The top plate portion B, that is, the surface side of the mounting portion T is formed of an "antibacterial coating K" as shown in FIG. 6 (b). Various methods can be selected for forming the antibacterial coating K. In the present embodiment, the following method is exemplified.

First, the beam 3 (hereinafter, referred to as "semi-finished product 30") before the formation of the antibacterial coating K is subjected to a degreasing treatment. In this degreasing treatment, a detergent is used to remove oils and fats attached to the surface of the semi-finished product 30. In this embodiment, the semi-finished product 30 previously formed into a desired shape is used.
Next, an embodiment in which the antibacterial coating K is formed is exemplified. However, even if the antibacterial coating K is formed on an aluminum material before the semi-finished product 30 is formed, and then the material is formed into a beam material shape, Good.

Next, the semi-finished product 30 is washed with water and then subjected to a caustic treatment. In this caustic treatment, for example, a caustic soda solution (for example, 5 to 8 wt%, 50 to 60 wt%)
C), oxides on the surface of the semi-finished product 30 are removed and washed.

Further, after the semi-finished product 30 is washed with water, a neutralization treatment is performed. In this neutralization process, for example,
Nitric acid or hydrochloric acid (for example, 10 to 15%) neutralizes caustic soda remaining on the surface of the semifinished product 30 and removes contaminant metals or compounds thereof remaining on the surface of the semifinished product 30. .

After the semi-finished product 30 is washed with water, anodizing treatment is performed. In this anodization, the semi-finished product 30 is used as an anode, oxygen is generated by electrolysis, and aluminum is oxidized to generate an aluminum layer.
At this time, for example, a direct current or an alternating current is supplied by using carbon, lead, or aluminum as an electrode on the cathode side.

As a result, as shown in FIG. 6B, anions are attracted to the surface 3A of the semi-finished product 30 (the surface before the anodization treatment), and oxygen is generated to generate a thin barrier layer (10 to 10).
50 nm) 3B is formed. At the same time, a small hole 3C in the center
A hexagonal column-shaped cell (diameter: 80 nm) 3D is formed. Then, the anion reaches the bottom of the cell 3D through the hole of the cell 3D, is oxidized through the barrier layer 3B, and the cell 3D grows. With the growth of this cell 3D,
The growth rate is suppressed, and the dissolution of the oxide film by the sulfuric acid electrolytic solution substantially stops the growth of the cell 3D, thereby forming an anodic oxide film (porous film) 3E of alumina (aluminum oxide).

Subsequently, the semi-finished product 30 is immersed in an aqueous solution of an antibacterial metal salt (for example, a salt of silver, copper, zinc, or the like), and the antibacterial metal 3F is formed in the small holes 3 of the anodic oxide coating 3E.
Adhere in C. Then, by the sealing process, the sealing 3G
Is performed, the formation of the antibacterial film K is completed, and a beam as a finished product is obtained.

As shown in FIG. 3, the bottom plate portion C constitutes the bottom portion of the pallet 1, and the five beam members 4
Are arranged along the lateral direction. The beam 4 is also manufactured by extrusion molding, and has a structure substantially similar to that of the beam 3 except that the antibacterial coating K is not provided on the surface side.

In the pallet 1 described above, since the surface side of the mounting portion T is made of the antibacterial film K, it is possible to transport the luggage in a cleaner and safer state. Hereinafter, this point will be described using experimental examples.

First, an aluminum test piece (hereinafter referred to as “executable product”) having the antibacterial coating K formed on the surface side, and an anodic oxide coating 3E not subjected to antibacterial treatment.
And a test piece made of aluminum (hereinafter, referred to as “comparative product”). On the other hand, the test bacteria include “Staphylococcus aureus”, “Escherichia coli”, and “Escherichia coli O-15”.
7 "were prepared and cultured in a normal broth medium (35
C, 18 hours) and dilute 500-fold with sterile purified water.
The solution adjusted to pH 7.0 ± 0.2 is defined as a bacterial solution.

Next, each of the three working products and the three comparative products was placed in a sterilized petri dish, and 0.5 μg of the bacterial solution was placed on each test surface.

Store for 24 hours (temperature; 35 ° C, humidity; 99%). After this storage, the bacteria adhering to the coated film are removed by SCD
Rinse with 10 ml of LP broth medium and 48
After culturing for a time (temperature: 35 ° C.), the number of bacteria is measured. Then, the average values of the three working products and the three comparative products are checked. still. For the control, the bacterial solution was added to 6 sterile dishes at the same time.
Inoculate 5 ml and cover with a covering film. The three sterile petri dishes are stored for 24 hours at a temperature of 35 ° C. and a humidity of 99%.

Immediately after the inoculation of the bacteria and after storage for 24 hours, the bacteria adhering to each of the coated films were removed by SCDL.
After washing with 10 ml of P-bouillon medium and culturing in SA medium for 48 hours (temperature: 35 ° C.), the number of bacteria is measured. Table 1 shows the average of the measured values.

[0046]

[Table 1]

According to Table 1, the sterilization rate (about; 99.9%) of “Staphylococcus aureus”, “Escherichia coli” and “Escherichia coli O-157” is high in the actual products. Therefore, according to the present pallet 1 having the same antibacterial coating K as that of the embodiment on the surface side of the mounting portion T, it is possible to transport the load in a cleaner and safer state. Therefore, food, medical products, drugs,
It can be particularly preferably used when conveying cosmetics and the like.

In the pallet 1, the antibacterial metal 3F
Is adhered into the small holes 3C of the anodic oxide coating 3E to form the antibacterial coating K. Therefore, even if the surface of the mounting portion T is worn or the surface of the mounting portion T is wiped with a rag or the like, the antibacterial property of the antibacterial coating K is not reduced.

Further, the present pallet 1 can be said to be a cleaner pallet 1 from the viewpoint that each of the pallets 1 is constituted by combining an aluminum beam 2 and beams 3 and 4. Since the pallet 1 is mainly composed of aluminum having high corrosion resistance, rust and the like are hardly generated. In addition, unlike a pallet mainly made of wood, there is no occurrence of "a nail dropout" or "scratch". Therefore, the rust, nails, wood chips, and the like do not enter the package to be transported.

In the pallet 1, when a fork is inserted below the top plate B, an insertion space formed between the left girder 2 and the center girder 2 is usually provided. An insertion space formed between the girder 2 and the center girder 2 is used. However, since the pallet 1 has an insertion opening 214 on the side surface of the core B (each girder 2), a fork is placed below the top plate B from a direction perpendicular to the axial direction of each girder 2. It can also be inserted.

That is, in a pallet provided with a mounting portion having a substantially rectangular planar shape, an insertion portion into which a fork is inserted is provided below the mounting portion by a pair of opposing side surfaces of the pallet (a core portion and a base portion). Is generally provided along the inter-plane direction. However, in the present embodiment, in addition to this insertion portion, another insertion portion is provided along the inter-surface direction of the side surface of another opposing pair of the pallet (the core portion and the base portion).
For this reason, in this pallet 1, the mounting portion T
A fork can be inserted below the Therefore, the pallet 1 is excellent in usability.

Further, as shown in FIG. 4B, the pallet 1 includes the upper partition plate 211 and the lower partition plate 212, so that even if the insertion direction of the fork F into the insertion opening 214 is oblique, The tip of this fork F is
11 in sliding contact with the lower surface or upper surface of the lower partition plate 212,
Follow. Therefore, it is easy to insert the fork F into the insertion opening 214. In the case where the upper partition plate 211 and the lower partition plate 212 are excluded from the beam 2, FIG.
As shown in the figure, when the insertion direction of the fork 4 is oblique,
In some cases, the tip of the fork F comes into contact with the inner wall surface of the girder member 2, which makes it difficult to insert the fork F.

Further, in the present pallet 1, as shown in FIG. 7, the contact area between the beam 2 and the fork F is increased by providing the upper partition plate 211. That is,
The entire lower surface of the upper partition plate 211 that can secure a sufficient area is a pressure receiving surface that comes into contact with the fork F. Therefore, even when a heavy object is mounted on the mounting portion T, the load can be received substantially evenly on the entire pressure receiving surface having a sufficient area, thereby preventing unnecessary deformation of the side wall plates 213a and 213b. it can. As shown in FIG. 8, when the upper partition plate 211 is removed from the girder member 2, the fork F comes into contact with the periphery of the insertion port 214 having a small end area. For this reason, when a heavy object is mounted on the mounting part T, there is a possibility that the side walls 213a and 213b may be unnecessarily deformed.

It should be noted that the scope of the present invention is not limited to those specifically described in the above embodiments, and various modifications can be illustrated within the scope of the configuration and the purpose of the present invention. That is, in the above-described embodiment, the aspect in which the surface side of the top plate portion B is configured with the antibacterial coating K is illustrated, but at least one of the surface side of the bottom plate portion C and the surface side of the core portion A is provided with an antibacterial It can also be constituted by the conductive film K. For example, when a plurality of pallets 1 are stacked and used vertically, the load on one pallet 1 comes close to the bottom plate portion C of another pallet 1 arranged directly above the pallets 1. .
In such a case, if the front side (lower side) of the bottom plate portion C is formed of the antibacterial coating K, bacterial contamination of the load from above can be prevented. When the front side (lower side) of the bottom plate C is made of the antibacterial coating K, the top plate B and the bottom plate C can be used upside down. Selfishness improves.

Further, there is no particular limitation on the number of spaces defined by the partition plate in the vertical cross section of the “column”, and other than the square shape as shown in FIG. The shape may be divided into two spaces by one plate. Further, the partition plate for creating the above space can be provided in the entire lateral direction of the stringer 2, but if it is provided at least above and / or below the notch hole for inserting a fork, the way of providing the partition plate is particularly limited. There is no. Incidentally, the end side of the vertical girder can be covered with a cap or the like.
