Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an identification tag (ID tag: iden) for identifying a pallet on a pallet for carrying a load and carrying it with a forklift or a handlift.
The present invention relates to a pallet with an identification tag provided with a tification tag), and particularly to a pallet with an identification tag capable of identifying the pallet from the side direction of the pallet by wireless communication.

[0002]

2. Description of the Related Art FIG. 1 is a diagram showing a general conventional pallet. As shown in FIG. 1, the pallet 1 is a planar cubic object and is usually made of synthetic resin. One of the surfaces of the pallet 1 having the largest area is used as a loading surface (deck board) 2 for loading luggage. The surface facing the loading surface 2 is
It is the back side. The loading surface 2 is also called a deck board. The side surface of the pallet 1 is composed of two types of surfaces.

One is a fork insertion surface (W direction) 3. The fork insertion port surface 3 is a surface having a fork pocket 5 used for holding the pallet 1 for moving a load such as a forklift or a handlift. A fork such as a forklift or a handlift is inserted into the fork pocket 5 to hold the pallet 1. Then, the pallet 1 is moved by moving the forklift, the handlift, or the like, and the load loaded on the pallet 1 can be transported. Further, the fork pocket 5 penetrates to the opposite side. That is, the facing surface is also the fork insertion port surface 3, and the facing surface is also formed with the same specifications.

The other is a girder surface (L direction) 4, which is not normally provided with holes or the like. Its main role is to reinforce the loading surface.

The direction in which the fork is inserted as shown in FIG. 1 is sometimes called the W direction, and the direction orthogonal to the W direction is sometimes called the L direction.

By the way, in a conventional synthetic resin pallet having an identification tag, an identification tag holder is attached from the outside to the central portion of the girder surface 4 shown in FIG. It is possible to write information in the identification tag by transmitting a signal having specific information to the identification tag by an external writing device. Further, by receiving the signal emitted by the identification tag by the external device, the external reading device can recognize the information possessed by the identification tag. Therefore, each pallet 1 can be managed by the identification tag.

A pallet 1 provided with an identification tag holder at the center of the girder surface 4 is described in, for example, Japanese Patent Application Laid-Open No. 9-254983. In the pallet described in Japanese Patent Application Laid-Open No. 9-254983, an identification tag holder, that is, an identification tag is installed at the center of the girder surface 4. Since one pallet has two girder surfaces 4, two identification tags are installed.

[0008]

However, since the identification tag is installed only on the surface of the girder surface 4, the distance from the direction 3 of the fork insertion surface to the identification tag holder is large, and It is likely impossible to read the information or write the information to the identification tag.
This possibility is determined by the minimum communication distance required to read from and write to the identification tag and the size of the pallet. As a typical example, in the identification tag, the communication limit distance at the time of reading is about 30 cm, and the communication limit distance at the time of writing is about 18 cm. Also, the pallet is 110 cm
It is x 110 cm x 14.4 cm (length in the L direction x length in the W direction x height). Therefore, if the identification tag and pallet of this example are described in JP-A-9-254983, it is impossible to read information from the identification tag and write information to the identification tag from the W direction. .

Therefore, in view of these problems in the prior art,
The object of the present invention is from all sides of the pallet,
It is to provide a pallet with an identification tag that allows information to be exchanged with the identification tag.

Another object of the present invention is to provide a pallet with an identification tag in which the identification tag is less susceptible to external damage.

[0011]

According to the present invention, there is provided a pallet made of a synthetic resin which is a rectangular parallelepiped, and a rectangular parallelepiped identification tag which is installed inside the pallet and has unique information for each pallet. It is provided by a palette with an identification tag.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the pallet with an identification tag of the present invention will be described below with reference to the drawings. Figure 2
FIG. 1A is a perspective view of a pallet with an identification tag according to the first embodiment of the present invention. A rectangular hole with a boundary line between the fork insertion surface 3 and the loading surface 2 and a straight line extending a long-sided line of the rectangle forming an angle of about 45 degrees is a loading surface 2 of the pallet 1. It is provided at the corner of. Further, the longitudinal direction of the rectangular hole on the loading surface into which the identification tag cassette 11 is inserted is perpendicular to the diagonal line of the loading surface. The straight line obtained by extending the long-sided line segment of this rectangle is the girder surface 4 and the loading surface 2.
It also forms an angle of about 45 degrees with the boundary line between and.

This hole has a depth perpendicular to the loading surface 2 which is equal to or greater than the length of the identification tag. Usually, the depth is about 10 cm. This depth is the length of the identification tag 12 and the identification tag 1
2 is determined by the size of the identification tag cassette 11 for mounting. The size of the identification tag 12 which is expected to be put into practical use at present is about 75 mm × 15 mm × 5 mm (length × width × width). Then, the identification tag cassette 11 equipped with the identification tag 12 is inserted into the hole. In this way, the identification tag 12 is externally attached to the identification tag cassette 1
1 and a pallet 1 made of synthetic resin, it is less likely to get wet with water and dust. Therefore, it is possible to provide a pallet with an identification tag that is durable and reliable, with less concern that the identification tag 12 will break down. Since the pallet 1 is washed with hot water of about 50 to about 70 degrees, the identification tag 12
Is important to be protected from water. Further, in this embodiment, the identification tag 12 is only in thermal communication with the outside through the identification tag cassette 11. Since the identification tag cassette 11 is made of synthetic resin, it has low thermal conductivity. Further, since the identification tag cassette 11 is exposed to the outside only in a small portion on the stacking surface, the identification tag cassette 11 is unlikely to have heat. therefore,
Since it is not easy for heat to conduct to the identification tag 12,
It becomes possible to protect the identification tag 12 from heat. This advantage is not found in conventional pallets.

The identification tag 12 of this embodiment can send and receive data wirelessly to and from an external reading or writing device using, for example, microwaves. The identification tag 12 has memory areas of a system area (currently 18 bytes: predetermined information is written when the tag is manufactured) and a user area (currently 110 bytes: freely rewritable by an application). In the system area, the individual number of the identification tag 12 is managed. Predetermined initial information is written in the system area when the tag is manufactured. In the user area, the company code,
The loaded product code, manufacturing date, quantity by loaded product, delivery destination code, etc. are read or rewritten. In the user area, the information contained in the application can be rewritten. This has a capacity that is several times or several tens of times that of conventional barcodes, and makes it possible to provide the palette with the function of a storage device that can manage information from a simple unique number.

FIG. 2B shows the identification tag cassette 11 mounted on the pallet as shown in FIG. 2A and the identification tag 12 mounted on the identification tag cassette 11.

The identification tag cassette 11 has at least two locking portions (11-1, 11-2). The locking portion is for preventing the identification tag cassette 11 from easily coming off the pallet 1.

Further, since the identification tag cassette 11 is removable, when the identification tag 12 is defective, the identification tag 12
It is easy to replace the identification tag 12 when changing the capacity of the. Therefore, even if the performance is improved by the accelerated technological innovation of the identification tag 12, the latest identification tag 12 can be installed on the pallet 1. Further, since the identification tag 12 can be exchanged without destroying the pallet 1, the latest pallet with the identification tag 12 can be always provided at low cost.

Further, the pallet 1 and the identification tag cassette 1
When discarding 1 or the identification tag 12 and recycling, it becomes easy to sort by material. Therefore, the cost for recycling can be kept low. Therefore, it will have a great effect on the environmental problems of synthetic resin pallets that will become popular in the future. In the pallet 1 of this embodiment, since the identification tag 12 made of a material different from that of the pallet 1 can be attached / detached,
It is possible to remove the identification tag 12 from the pallet 1 and crush the synthetic resin to utilize it as a recycled raw material.

The identification tag cassette 11 is usually made of synthetic resin. However, a material such as metal may be used. In particular, it is effective to use a metal plate having a high conductivity for the portion 11-3 where the identification tag 12 is attached in order to extend the communication distance. The metal plate plays the role of a reflection plate, and the metal plate reflects an electromagnetic wave that propagates a communication signal, so that the communication distance becomes longer than when the metal plate is not used.

As described above, by installing the identification tags 12 at the corners of the pallet 1, it is possible to bring the reading or writing device closer within the communicable distance in both the L and W directions. Therefore, it becomes possible to read information from the identification tag 12 and write information to the identification tag 12 from both directions of the L direction and the W direction.

FIG. 3A is a top view of the pallet.
The identification tag cassette 11 is installed so that the flat surface portion of the identification tag 12 having the largest area faces the outside of the corner of the pallet. That is, the identification tag 12 is installed so that the radio waves transmitted from the identification tag 12 or input to the identification tag are equal in the L direction and the W direction.

Further, the pallets 1 used in physical distribution are susceptible to external damage on the side surfaces (L and W directions) by a fork such as a forklift. However, the loading surface is less susceptible to external damage such as forklifts. Therefore, as in this embodiment, from the loading surface 2 to the identification tag cassette 11
Inserting is effective in that the identification tag cassette 11 and the identification tag 12 are less likely to be damaged.

FIG. 3B shows the case where the identification tag 12 having a directivity of 90 degrees is installed. In the case of the identification tag 12 having the directivity of 90 degrees as described above, the W from the L direction is centered on the middle direction of the L direction and the W direction.
The effective angle is up to the direction.

By the way, pallets 1 used for physical distribution are generally handled with the L direction or the W direction aligned. When attaching the identification tag 12 to the pallet 1, if the identification tag 12 with directivity is used, L
The reading direction and the writing direction of the identification tag 12 are limited to the direction or the W direction. Even if there is no directivity, if the communicable distance is short, the distance to the reading or writing device may be longer than the communicable distance depending on the installation location of the identification tag 12, and communication may not be possible. is there.

In this embodiment, by installing the identification tags 12 at the corners of the pallet 1, even if an external reading and / or writing device is arranged in the L direction and the W direction, the identification tags 12 can be connected to the identification tags 12. Communication becomes possible.

The distribution pallet 1 is for loading products and distributing the products from the producer side to the consumer side. At production bases, automation of production equipment is advancing,
Belt conveyors are used. The produced products are automatically loaded on the distribution pallet 1 and moved on the conveyor line. Identification tag 12 installed on the conveyor line
The reading device and the writing device are installed in the L direction of the physical distribution pallet 1. Therefore, it is necessary to arrange the reading and / or writing device within the communication range of the identification tag in the L direction.

On the other hand, at a distribution site near the place of consumption, cargo handling by a forklift or a handlift is the mainstream.
As a result, since the work from the W direction is the center, it is necessary to arrange the reading and / or writing device within the communicable distance of the identification tag 12 also in the W direction.

In the case of a conventional pallet having an identification tag holder attached to the central portion of the girder surface 4, at the physical distribution site near the consumption center where the work from the W direction is the center, it is not practical because of the limit of the communicable distance. Was missing. In this embodiment, the identification tag is embedded in the corner portion of the distribution pallet at an angle of 45 ° so that the identification function of the pallet 1 can be used both at the production base and at the distribution site near the place of consumption. As a result, it is possible to bring the reading and / or writing device close to the L direction and the W direction within about 18 cm, and a practical identification tag that can be used from the production base to the physical distribution site near the consumption place is provided. It becomes possible to realize the attached pallet 1.

Further, according to the pallet with an identification tag of this embodiment, in the distribution environment of the consistent palletization in which the shipper loads the merchandise on the pallet 1 and transports the goods to the shipper, the identification tag 12 is used to store the transaction information. It becomes possible to perform management. Therefore, there is a possibility that the transaction slip can be abolished. Also, the information of the shipper is the identification tag 1
Reading from 2 can reduce inspection work.

Furthermore, since the identification tag 12 is arranged inside the pallet 1, a fork such as a forklift and a handlift hits the vicinity of the identification tag 12,
The identification tag 12 is less likely to be damaged.

Further, since the identification tag 12 is isolated from the outside by the synthetic resin, even in the case of a drastic environmental change such as outside temperature and humidity, the vicinity of the identification tag 12 makes a gradual environmental change. . Therefore, it becomes possible to provide the identification tag cassette 11 having the identification tag 12 suitable for the pallet 1 that is often used in a harsh environment.

FIG. 4A shows the pallet 1 viewed from the direction of the girder surface 4. FIG. 4B is a cross-sectional view taken along the line AB of FIG. According to FIG. 4B, the identification tags 12 mounted on the identification tag cassette 11 are arranged at the corners of the pallet 1. Further, as described above, the identification tag 12 is arranged in the hollow portion of the rib structure of the pallet 1 at an angle of 45 degrees.

FIG. 5 is a top view of a pallet with an identification tag according to the second embodiment. In this embodiment, it is shown that the identification tag cassettes 11 to which the identification tags 12 for identifying the pallet 1 are attached are installed in all of the four corners of the pallet 1. Each identification tag cassette 11
Like the identification tag cassette 11 in the first embodiment, is installed at the corner at the above-mentioned angle of 45 degrees.

As described above, when the identification tags 12 are installed in the four corners, it is not necessary to consider which side of the belt the identification tag reader and writer provided near the belt conveyor should be installed. . Further, even when the pallet 1 is transported by a forklift or a handlift, it is not necessary to consider which direction of the two fork insertion surface 3 of the pallet 1 is to be inserted. Furthermore, on which side of the two forks,
There is also no need to negotiate whether a reading and / or writing device for the identification tag 12 is provided.

FIG. 5B is a top view of the pallet with an identification tag according to the third embodiment. The difference from the pallet with the identification tag of the second embodiment is that the identification tag cassette 11
Is installed near the midpoint of four sides of the pallet 1 with an identification tag. In this case, an identification tag reader and / or writer installed on a forklift or a handlift is provided between the forks.

FIG. 6A shows the corners of the pallet with identification tags of the first and second embodiments. FIG. 6B shows a corner portion of the pallet with an identification tag according to the fourth embodiment. FIG. 6B is a vicinity of a corner where the identification tag cassette 11 in FIG. 6A is provided, and holes 6 are formed near the corner of the girder surface 4 and near the corner of the fork insertion surface 3, respectively.
Is provided. As a result, in the first and second embodiments, the portion where the synthetic resin was provided becomes hollow. Therefore, there is an effect that the electromagnetic wave attenuated by the synthetic resin is not attenuated. This is expected to increase the communicable distance between the identification tag reading device and / or the writing device and the identification tag, as compared with the case where the synthetic resin is present.

FIG. 6C shows a corner of the pallet with an identification tag according to the fifth embodiment. FIG. 6C is the same as FIG.
This is a case where the synthetic resin between the two holes 6 in (B) is also removed to provide a larger hole 7. According to this, since the hollow portion further expands, the communicable distance between the identification tag 12 and the reading device and / or the writing device of the identification tag 12 is larger than that in the pallet with the identification tag according to the fourth embodiment. Expected to grow.

FIG. 7 shows a corner of a pallet with an identification tag according to the sixth embodiment. In this embodiment, a new wall surface is provided inside the pallet so that the identification tags 12 are arranged at the same angle as in the first embodiment. This wall surface corresponds to the identification tag cassette 11 of the first embodiment. The position where the identification tag 12 is installed is the same as in the case of the first embodiment.

Since the identification tag 12 is completely isolated from the outside by the synthetic resin of the pallet 1, it is unlikely that the identification tag 12 gets wet with water or dust is attached to the identification tag 12. . Therefore, the risk of the identification tag 12 breaking down is greatly reduced, and a pallet with an identification tag having durability and reliability can be provided.

FIGS. 8A and 8B are top views of a pallet with an identification tag according to the seventh embodiment. Figure 8
8C is a cross-sectional view taken along the line segment AB of FIG.
In this embodiment, as shown in FIG.
As in the above embodiment, holes are provided at the corners on the loading surface 2. Then, a pedestal 16 of synthetic resin is provided inside the facing surface of the stacking surface 2, the identification tag 12 is inserted from the hole, and the identification tag 12 is placed on the pedestal 16. Finally, grommet 1 made of synthetic resin
The hole is closed at 5, and the identification tag 12 is fixed by the grommet 15 and the pedestal 16. The identification tag 12 is arranged in a form similar to that of the first embodiment.

By the grommet 15, the grommet 15
The part marked with swells up a little, and it looks like a protrusion just on the loading surface 2. However, since a slip stopper or the like having the same height as that is installed on the loading surface 2,
There is almost no concern that the grommet 15 will be hit by luggage and destroyed. This embodiment is also the sixth
The identification tag 12 can be held in the pallet 1 while maintaining airtightness as in the above embodiment. Furthermore, in the pallet 1 of this embodiment, the identification tag 12 can be attached and detached by breaking the grommet 15.

FIG. 9 is a sectional view showing a pallet with an identification tag according to the eighth embodiment. FIG. 9 is a cross-sectional view of a cross section corresponding to the line segment AB shown in FIG.

In this embodiment, the identification tag 12 is inserted from the fork insertion surface 3 near the corner of the pallet with the identification tag, and is capped with a cap. The identification tag 12 is arranged in the same form as in the first embodiment.

Of course, holes may be formed not only from the fork insertion surface 3 but also from the girder surface 4 so that the identification tag 12 can be inserted from the girder surface 4.

In this embodiment as well, as in the sixth and seventh embodiments, the identification tag 12 can be held in the pallet 1 while maintaining airtightness. Furthermore, in the pallet 1 of this embodiment, the identification tag 12 can be attached and detached by removing the cap.

FIG. 10A is a perspective view of a pallet with an identification tag according to the ninth embodiment. FIG. 10 (B) shows
An identification tag cassette 11 attached to the pallet with an identification tag shown in FIG.
1 shows the identification tag 12 attached to 1. The identification tag cassette 11 and the identification tag 12 are the same as the identification tag cassette 11 and the identification tag 12 of the first embodiment.

In this embodiment, the identification tag cassette 11
Is different from the pallet with the identification tag of the first embodiment only in the direction in which is installed. That is, in this embodiment, the longitudinal direction of the rectangular hole on the loading surface 2 into which the identification tag cassette 11 is inserted is parallel to the diagonal line from the corner near the identification tag cassette 11 on the loading surface 2. Further, a rectangular hole having a boundary line between the fork insertion surface 3 and the loading surface 2 and a straight line obtained by extending a line segment in the long direction of the rectangle forms an angle of about 45 degrees is used for loading the pallet 1. It is provided at a corner of the surface 2. Also,
A straight line obtained by extending a line segment in the long direction of the rectangle forms an angle of about 45 degrees with the boundary line between the girder surface 4 and the loading surface 2. Figure 11
FIG. 11 is a cross-sectional view of the pallet with an identification tag shown in FIG. 10 (A) taken along a plane similar to the cross section taken along the line AB of FIG. 4 (A). The identification tags 12 attached to the identification tag cassette 11 are arranged at the corners of the pallet. In addition, as described above, the cavity of the rib structure of the pallet is
The identification tags are arranged at an angle of 5 degrees.

The rest is the same as the pallet with the identification tag of the first embodiment. First, depending on the directivity of the identification tag
Alternatively, it is desirable that either the ninth embodiment is selected and applied.

FIG. 12A is a perspective view of a pallet with an identification tag according to the tenth embodiment. FIG. 12 (B)
FIG. 13 is a cross-sectional view of the pallet with an identification tag shown in FIG. 12 (A) taken along the same plane as the cross section along the line AB in FIG. 4 (A). The identification tag 12 is inserted into the pallet 1 at an angle of 45 degrees as in the case of the ninth embodiment. FIG. 12 (C) shows a state in which the cap 17 is attached to the pallet with the identification tag shown in FIG. 12 (A). FIG. 13 is a diagram showing FIG. 12B in more detail. A hole into which the identification tag 12 and the cap 17 are inserted is provided at a corner of the pallet 1 at an angle of 45 degrees. In this embodiment, the identification tag 12 is inserted into the hole provided in the pallet 1 from the side surface of the corner. The holes extend from the corners of the pallet 1 toward the center of the pallet 1.
The holes are provided so that the identification tags 12 are arranged in the pallet 1 as in the first embodiment. That is, the hole is such that the height is the length of the longest side of the identification tag 12, the depth is the length of the next longest side of the identification tag 12, and the width is the length of the shortest side of the identification tag 12. It is provided corresponding to.
Of course, the holes are made slightly larger than the size of the identification tag 12. Further, since the cap 17 is inserted into the hole after the identification tag 12 is inserted, the cap 17
The length of the minute is taken into account to determine the depth of the hole. By arranging the identification tag 12 in this way, the same effect as that of the first embodiment can be obtained. In this embodiment, the identification tag 12
Is isolated from the outside by the cap 17. Cap 17
Since the is removable, it is easy to replace the identification tag 12 when the identification tag is defective or when the capacity is changed.
Furthermore, the pallet 1 and the identification tag 12 are discarded,
When recycling, sorting by material becomes easy. Therefore, the cost for recycling can be kept low. The material of the cap 17 is preferably an elastic material such as synthetic resin. With such a material, the outside and the identification tag 12 can be isolated with high accuracy. It is also expected that the cap 17 can be easily attached and detached.

The hole may be inserted into the hole when the identification tag 12 is in a horizontal state. That is, in the case where the identification tag 12 is in the horizontal state, the depth is the length of the longest side of the identification tag 12, the height is the length of the next longest side of the identification tag 12, and the width. Is provided corresponding to the length of the shortest side of the identification tag 12. Of course, the holes are made slightly larger than the size of the identification tag 12. Further, since the cap 17 is inserted into the hole after the identification tag 12 is inserted,
The depth of the hole is determined in consideration of the length of the cap 17 minutes. By arranging the identification tag 12 in this way, the same effect as that of the first embodiment can be obtained. However, the identification tag 12
In some cases, the communication distance becomes extremely short in the direction perpendicular to the surface having the smallest area. When the identification tag 12 is inserted horizontally into the hole, the communicable distance is extremely short in the direction perpendicular to the lateral direction of the pallet, in the direction in which the identification tag 12 is arranged, from the center of the pallet. Become. In addition, the communication range of the identification tag 12 is widened toward the upper surface and the lower surface of the pallet 1. In this case, when a plurality of pallets 1 are loaded, it is difficult to distinguish between a pallet 1 and a pallet 1 above or below the pallet 1 and communicate with the identification tag 12 of each pallet 1. There is. That is, even if an attempt is made to communicate with a certain pallet 1, the communication range of the identification tag 12 is within the pallet 1
Since it extends in the stacking direction, there is a possibility that communication will occur with the identification tag 12 of the pallet 1 arranged above or below the pallet 1. This makes it impossible to exchange information with a desired pallet. Therefore, in the case of this identification tag, it is preferable to install the identification tag 12 in the same arrangement as in the first embodiment. Since the arrangement of the identification tag 12 depends on the communicable distance and the communicable range of the ID, it is preferable to arrange the identification tag 12 in the pallet according to the performance of the identification tag 12.

In this embodiment, the holes are provided at the corners of the side surface of the pallet, but the holes are provided in the vicinity of the fork insertion surface 3, girder surface 4, loading surface 2, or facing the loading surface 2,
The identification tags 12 may be arranged at the corners of the pallet 1.
There can be various variations in the installation of the holes.
What is important is that the identification tag 12 is arranged as in the first embodiment. Further, the form of arrangement of the identification tags 12 is determined depending on the performance of the identification tags 12, as described above. The placement of the identification tag 12 described herein is important in all embodiments herein. For example,
In the above, the identification tag 12 is embedded in the pallet 1 at an angle of 45 degrees, but since it varies depending on the performance of the identification tag, there is a possibility that there is an effective angle depending on the identification tag other than this angle.

FIG. 14 (A) is a perspective view of a pallet with an identification tag 12 in the pallet with an identification tag according to the eleventh embodiment of the present invention. FIG. 14 (B)
Is a state in which the grommet 23 is inserted from the upper surface and the lower surface shown in FIG. 14 (A) and the identification tag 12 is fixed, from the upper surface along the line segment AB shown in FIG. 14 (A). It is sectional drawing which crossed to the lower surface. FIG. 14 (C)
FIG. 14 is a cross-sectional view taken along a line segment AB shown in FIG. In the above-described embodiment, there is only one hole for inserting the identification tag 12. In the eleventh embodiment, the pallet 1 is provided with a through hole 21 penetrating between the upper surface and the lower surface thereof.
An identification tag 12 is placed inside.

When only one surface is closed (for example, a hole in which the lower surface of the through hole 21 in FIG. 14A is closed is assumed), the grommet for arranging the identification tag 12 is arranged. By the time 23 is inserted into the hole, dust such as dust may collect at the bottom of the hole. Moreover, depending on the place where the pallet 1 is stored, insects may make the bottom of the hole live. When the pallet 1 is manufactured and the grommet 23 is used to attach the identification tag 12 immediately, such a problem does not occur easily, but when there is a period after the pallet 1 is manufactured until the hole is closed with the grommet or the like. Are likely to cause the problems described above. Then, an extra step of removing dust such as dust and insects and cleaning the hole becomes necessary.

Therefore, by providing the through hole 21 as shown in FIG. 14 (A), dust or the like will often escape even if it enters the through hole 21. Therefore, it is less likely that dust or insects such as dust will remain in the hole, and there is a high possibility that the step of cleaning the hole becomes unnecessary.

As shown in FIGS. 14 (A) to 14 (C), the inner surface of the through hole 21 is provided with a convex portion 22 for locking the grommet 23 inserted into the through hole 21. There is. The convex portion 22 fits into the concave portion 25 provided in the grommet 23 to lock the grommet 23.
The recess 25 is a shaft portion of the grommet 23, that is, a side surface portion of the grommet 23 that comes into contact with the through hole 21 during insertion. As a result, the grommet 23 has the through hole 2
It is fixed in 1 and cannot rotate about its axis.

The relationship between the convex portion 22 and the concave portion 25 may be reversed. That is, a concave portion may be provided on a part of the side surface of the through hole 21 and a convex portion may be provided on the shaft portion of the grommet 23. Also in this case, it is possible to set such that the concave portion and the convex portion are locked and the grommet 23 cannot rotate about the shaft in the through hole 21.

As shown in FIG. 14C, the identification tag 12 is arranged so that the surface having the largest area faces the outside of the corner of the pallet. Not limited. For example, like the arrangement of the identification tags 12 in the ninth embodiment, the identification tags 12 may be arranged so that the surface having the second largest area faces the pallet corner. Further, depending on the performance of the identification tag 12, if the other direction is preferable in communication, it is preferable to arrange the identification tag in that direction.

The identification tags 12 are arranged in the convex portion 22.
Alternatively, it is set by changing the position where the recess 25 is provided from the position shown in FIG.
Of course, both the positions of the convex portion 22 and the concave portion 25 may be changed and set.
