According to the present invention, since a sufficient distance is secured between the wireless tag and the metal frame material so as to be 1/3 or more of the communication wavelength, the wireless tag is provided in the center of the pallet body. However, there is no risk that the antenna matching will be out of order, and problems such as a decrease in transmission / reception sensitivity will not occur. Therefore, it becomes possible to reliably receive the information from the wireless tag and facilitate the management of the movement route of the pallet and the building material, and the tag writer writes various information without considering the orientation of the pallet. You will be able to do it.

It is a perspective view of the pallet for a building material which is an embodiment of this invention. It is a perspective view of the state which the building material is mounted on the pallet for building material shown in FIG. It is a top view of the pallet for building materials shown in FIG. It is a side partial fracture view of the building material pallet shown in FIG. It is a vertical side view which enlarged the main part of the pallet for building materials shown in FIG.

Hereinafter, a preferred embodiment of the pallet for building materials according to the present invention will be described in detail with reference to the accompanying drawings.
1 to 5 show a building material pallet according to an embodiment of the present invention. The building material pallet 1 exemplified here is applied to transport building materials that are components of fittings and exteriors. For example, building materials that are components of fittings include frame materials, frame materials, glass, doors, and the like. Building materials that are components of the exterior include fences and gates. As for frame materials such as frame materials, stile materials, and fences, those arranged in the horizontal direction are transported in a state of being stacked in multiple stages. On the other hand, face materials such as glass, doors, and gates are transported in a leaning state.

The building material pallet 1 includes a pallet body 10 for mounting the building material F. The pallet body 10 is configured by arranging two frame portions 12, 13 configured by combining a plurality of frame members 11 one above the other. Each of the frame portions 12 and 13 has a rectangular grid shape in outer shape, and is configured to have the same size as each other. The frame portion arranged above (hereinafter referred to as the upper frame portion 12 when distinguished) and the frame portion arranged below (hereinafter referred to as the lower frame portion 13 when distinguished) are vertically aligned between each other. By interposing a plurality of connecting members 14, they are connected to each other in a state where a space 15 having a constant height is secured. To give specific dimensions as an example, in the present embodiment, the pallet body 10 having dimensions of 2000 mm on the long side, 1015 mm on the short side, and 111 mm in height is configured. As the frame member 11, a material having a square cylindrical cross section with a side of 20 mm and forming a square cylinder is applied. A height of about 70 mm is secured between the upper frame portion 12 and the lower frame portion 13. The building material F is mounted on the pallet body 10 in a state where a resin sheet (not shown) called a step plastic is arranged on the upper surface of the upper frame portion 12.

At the edges of the pallet body 10 which are the long sides, the support members 16 are erected at the portions at both ends of the pallet body 10. The strut member 16 includes a base 16a fixed to the pallet body 10 and a strut portion 16b provided flexibly at the upper end of the base 16a. Although not explicitly shown in the figure, a recess is provided on the bottom surface of each base 16a. The recess is configured to accommodate the upper end of the support column 16b and the upper end of the base 16a. Therefore, when the support column 16b is projected upward, the support column 16b of the building material pallet 1 arranged below is housed in the recess of the building material pallet 1 arranged above, so that the pallet body 10 can be accommodated. With the building material F mounted, it is possible to stack a plurality of building material pallets 1 one above the other. On the other hand, when each support column portion 16b is bent, the height of the support column member 16 becomes the height of the base 16a, and the height of protrusion from the pallet body 10 becomes small. Therefore, an empty building material pallet on which the building material F is not mounted can be stacked up and down with the pallet body 10 in close proximity to each other by accommodating the upper end portion of the base 16a in the recess.

A wireless tag 20 is arranged at the center of the pallet body 10. In this embodiment, a wireless tag 20 that communicates with a radio wave having a frequency of 920 MHz (≈ wavelength 325 mm) is applied. Although not explicitly shown in the figure, the wireless tag 20 includes a passive tag antenna, a memory, a vibration sensor, a temperature sensor, and a battery 21. The built-in battery 21 serves as a power source when operating as an active tag with the tag reader. The communication range between the wireless tag 20 and the tag reader is approximately 300 m. On the other hand, the wireless tag 20 operates as a passive tag with the tag writer. When operating as a passive tag, it is possible to wirelessly communicate with the tag writer within a range of about 1 m and write desired information in the memory. The external dimensions along the top and bottom of the wireless tag 20 are substantially equal to the height of the space 15 secured between the upper frame portion 12 and the lower frame portion 13.

As is clear from the figure, the above-mentioned wireless tag 20 is housed in the central portion of the rectangular parallelepiped storage box 30 formed of resin, and then arranged in the storage portion 17 formed in the pallet body 10. The accommodating portion 17 is a rectangular parallelepiped space surrounded by a rectangular frame 18 provided in the central portion of the upper frame portion 12 and a rectangular frame 19 provided in the central portion of the lower frame portion 13, and the accommodating box 30 is provided without a gap. It is configured to have dimensions that can be fitted without protruding from the building material pallet 1. More specifically, in each of the frame portions 12 and 13, the line of intersection between the vertical plane that bisects the short side and the vertical plane that bisects the long side is the central axis. Rectangular frames 18 and 19 are provided by the material 11. A minimum distance d of 150 (> 325/3) mm is secured between the wireless tag 20 and the frame member 11 constituting the rectangular frames 18 and 19.

According to the building material pallet 1 configured as described above, the frame material 11 constituting the rectangular frames 18 and 19 becomes the conductive member closest to the wireless tag 20, and the wireless tag 20 and the frame material 11 A space of 150 mm is secured between them. As a result, although the wireless tag 20 is provided in the center of the pallet body 10 made of the metal frame material 11, there is a possibility that the antenna matching may be out of order due to the interaction with the frame material 11. However, the gain of the antenna is secured. Therefore, for example, when the building material pallet 1 equipped with the building material F is delivered to a factory equipped with a tag reader, the information stored in the memory of the wireless tag 20 can be received by the tag reader, and the building material pallet 1 can be received. It becomes possible to facilitate the management of the moving route of the building material F and the building material F mounted on the building material pallet 1.

Here, even if a building material F such as a frame material formed of a metal such as an aluminum alloy is mounted on the building material pallet 1, the long ones are regularly and periodically arranged, so that the pallet body is the main body. The upper surface of 10 is not completely covered. Further, even when a face material such as a door or glass is mounted on the building material pallet 1, the upper surface of the pallet body 10 is not completely covered if it is in a leaning posture. Therefore, the radio wave transmitted upward from the wireless tag 20 provided in the central portion of the pallet body 10 is output upward through the gap formed between the building materials F, and surely reaches the tag reader. Will be done.

It is necessary to update or delete the information of the wireless tag 20 for the building material pallet 1 that has been emptied by lowering the building material F. According to the building material pallet 1 described above, the wireless tag 20 is arranged facing the space 15 between the upper frame portion 12 and the lower frame portion 13. Therefore, if the tag writer is operated from the space 15 between the upper frame portion 12 and the lower frame portion 13 toward the center of the pallet body 10, the wireless tag 20 does not consider the orientation of the building material pallet 1. You will be able to update or delete the information in.

It should be noted that the dimensions and numerical values shown in the above-described embodiments are merely examples and do not limit the present invention in any way. For example, as the wireless tag, of course, a tag whose communication wavelength is centered on a radio wave other than 920 MHz may be applied. In this case, it goes without saying that the distance secured between the frame material and the frame material is not 150 mm, and the value is changed according to the wavelength. Further, as the pallet main body 10, the one provided with the upper frame portion 12 and the lower frame portion 13 is exemplified, and the wireless tag 20 is provided in the space 15 between the frame portions 12 and 13, so that the pallet main body is provided. The wireless tag 20 can be seen through the space 15 from the side of the 10, and it is possible to more easily write information by the tag writer. However, in the present invention, the pallet body does not necessarily have to include the upper frame portion and the lower frame portion.
