Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, recently, as building materials, flash materials that are lightweight and easy to transport are often used. A flash material is a material in which a veneer such as a plywood is attached to a framed core material, and there are various types with different materials, uses, thicknesses, dimensions, etc. It would be convenient if these could be easily identified. Flash materials are used, for example, on ceilings, walls, floors, etc. However, since the material, use, thickness, dimensions, etc. of the flash material cannot be known from the appearance, the work progresses if information about the core material can be obtained by some method.

[0005] The present invention focuses on the above points, and an object thereof is to provide a building material capable of distinguishing the types of building materials and improving the work efficiency at the site, and a management method thereof.

Means for Solving the Problems

[0006] The building material of the present invention is characterized in that an electronic tag recording a UID associated with building material information stored in a management server is attached inside the building material. According to one of the main forms, an electronic tag is attached to the core material of the flash material. The portable information terminal of the present invention is characterized in that it inquires of the management server the building material information corresponding to the UID of the electronic tag of the building material and displays it. According to one of the main forms, when the UIDs of a plurality of electronic tags are detected, the building material information of the UID with the highest signal strength is displayed (Claim 4). Alternatively, the UIDs of a plurality of electronic tags are detected, and the building material information of the UID designated by the operator is displayed from among them (Claim 5). The building material management system of the present invention includes a tag reader that reads out the UID of the electronic tag from the building material, a management server that stores the building material information corresponding to the UID read by the tag reader, and a portable information terminal that reads out and displays the building material information corresponding to the UID read by the tag reader from the management server. The above and other objects, features, and advantages of the present invention will become clear from the following detailed description and the accompanying drawings.

Effects of the Invention

[0007] According to the present invention, an electronic tag is provided inside the building material, the building material information is stored in the management server corresponding to the UID of the electronic tag, and this is appropriately read out and displayed on the portable information terminal. Therefore, the types of building materials can be easily identified, and the work efficiency at the site can be improved.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

Examples

[0010] FIG. 1(A) shows a state where an electronic tag is attached to a flash material in this embodiment. In this embodiment, for example, an RFID tag is used as the electronic tag. As is well known, RFID (Radio Frequency Identification) is a system that reads and writes data of an RFID tag non-contact using radio frequencies. As shown in FIG. 1(A), a panel 10 of the flash material (the panel 10 is used, for example, for ceilings, walls, floors, etc.) has a configuration in which plywood sheets 14 and 16 such as veneer are attached to the front and back of a framed core material 12. In the illustrated example, it is rectangular, but there are various shapes and sizes. The RFID tag 100 is attached at an appropriate position within the space inside the panel 10. By doing so, there are advantages that damage to the RFID tag 100 is prevented and the appearance is good because it does not affect the appearance of the panel.

[0011] Figure 1(B) shows the overall configuration of the management system that uses the RFID tag 100. The RFID tag 100 of the panel 10 described above is read by the tag reader 200, and the read result is transmitted to the tablet 300. For data transmission and reception, various short-range wireless communication standards such as bluetooth and infrared can be applied. An application 310 for panel management is pre-installed on the tablet 300. These tag readers 200 and tablets 300 are prepared in the required numbers at the manufacturing factory of the flash material or the construction site. The tablet 300 is connected to the Internet 400 through a wireless LAN (not shown) provided at the factory or the site, and is further connected to the management server 500 of the panel 10.

[0012] Among these, as shown in Figure 2(A), the tablet 300 has the panel management application 310 installed, and thereby communicates with the tag reader 200 and the management server 500. And, a, the panel UID 320 of the RFID tag 100 obtained from the tag reader 200, b, the radio wave intensity 322 of the RFID tag 100, c, the panel information 324 of the UID obtained through the exchange of information with the management server 500, d, the GPS (position) information 326 of the tag reader 200 to the tablet 300, are to be displayed on the tablet 300. In the illustrated example, there are three panels 10, and for them, the panel UID 320, the radio wave intensity 322, the panel information 324, and the GPS information 326 are respectively displayed. The panel information 324 corresponds to the panel information 522 of the management server 500 described later. Note that the two do not necessarily have to match, and a part of the panel information 522 may be displayed as the panel information 324. The GPS information 326 is used for specifying the location of the factory where the work is performed from the location of the tablet 300.

[0013] Next, as shown in FIG. 2(B), the management server 500 has a management program 510 prepared, and information exchange with the tablet 300 is thereby enabled. Also, the information of the panel 10 is integrated in the database 520. An example of the panel information 522 is shown in FIG. (C), and a, lot number, b, panel part number, c, production drawing, d, core material area, e, material, f, application, g, dimensions, h, manufacturing date, i, manufacturing company, etc. apply. These panel information 522 are listed for each UID of the panel 10. If necessary, information such as the construction site where the panel 10 is installed, the room number where it is installed, and the number of panels per room is added as needed. (These panel information are manufactured in a factory or the like and are input into the database at least before shipment.)

[0014] Next, the panel manufacturing process will be described with reference to FIG. 3. FIG. 3 shows the main processes in the manufacturing factory of the panel 10. (1) Material Incoming (Step S10) (2) Wood Cutting Process (Core Material Cutting) (Step S12) (3) Affix the RFID tag 100 to the cut core material 12 (Step S14): In this embodiment, at this point, the RFID tag 100 associated with information such as materials and dimensions is affixed to the core material 12 at a predetermined position. (4) Face Material Cutting Process (Surface Material Cutting) (Step S16) (5) Frame Assembly Process (Panel Frame Assembly) (Step S18) (6) Core Placement Process (Step S20) (7) Pressing Process (Step S22) (8) Leader reading and press machine setting change (Step S24): Read the RFID tag 100 of the panel 10 to be pressed, read the corresponding panel information 522 from the management server 500, and change the setting conditions of the press machine. (9) Running saw process (Step S26) (10) Tenoner process (Step S28) (11) Leader reading and tenoner machine setting change (Step S30): Read the RFID tag 100 of the panel 10 to be pressed, read the corresponding panel information 522 from the management server 500, and change the setting conditions of the tenoner machine. (12) Finishing (Step S32) (13) Multiple-piece picking (Step S34) (14) Mechanism (Step S36) (15) Floor door-to-door packaging (RFID tag attachment in the case of external sticking) (Step S38) (16) Shipping process (Step S40) (17) Leader reading (verifying with the packing list to prevent shipping omissions and mistakes) (Step S42): Read the RFID tag 100 of the panel 10 before shipping, read the corresponding panel information 522 from the management server 500, and verify it with the packing list. This can prevent shipping omissions and mistakes.

[0015] In each of the above processes, the work is carried out in the procedure of reading the operator's nameplate → executing the work → updating the panel information → finishing the work. For example, when detailing the process of (3) above, it is as follows. At this time, a, Display the initial screen on the tablet 300, b, Start the work, c, Scan the barcode of the operator's nameplate to read the operator information on the tablet 300 (it may be possible to use the RFID tag 100 as the barcode and read it with the tag reader 200). d, Read the UID of one or more RFID tags 100 (in the case of multiple, it will be consecutive UIDs), e. Access the management server 500 from the tablet 300 and update the disclosure time and the person in charge of this process. f. Receive the panel information 522 such as the manufacturing number corresponding to the read UID from the panel information database 520 of the management server 500 and display it on the tablet 300. g. Affix the RFID tag 100 that has undergone the above processing to the core material 12 (for example, before affixing to the core material, the tag is affixed to something like a sheet, and then it is peeled off one by one and affixed to the core material), and the work is completed. Finally, read the affixed RFID tag 100 with the tag reader 200, check whether the panel information 522 displayed on the tablet 300 is the same as the product, and access the management server 500 to update the end time.

[0016] As described above, in the manufacturing process of the panel 10, the RFID tag 100 associated with the panel information 522 of the panel 10 to be affixed is affixed to the cut core material 12. Then, the RFID tag 100 is read with the tag reader 200, and the management server 500 is accessed with the tablet 300, and the panel information 522 of the panel 10 is read and displayed. In the press process and the tenoner process, appropriate press and tenoner operations are performed with reference to the panel information 522 of the tablet 300. Also, the inspection of the panel 10 before shipment is performed with reference to the panel information 522 of the tablet 300.

[0017] Next, referring to FIG. 4, the installation and assembly process of the panel 10 at the construction site will be described. First, the case of constructing one panel 10 at a time will be described. The main processes are as follows. (1) Panel loading (step S50) (2) Read only one RFID tag with the tag reader 200 (step S52) (3) Display the panel information corresponding to the UID of the read RFID tag 100 (step S54)

[0018] In this case, the panels 10 carried into the site are generally stacked as shown in Fig. 1(B). Here, when the tag reader 200 attempts to read the RFID tags 100 of multiple panels 10, the signal strength from the topmost panel 10 is strong, and the signal strength from the bottommost panel 10 is weak. Therefore, in this embodiment, the UID of the RFID tag 100 obtained for the topmost panel 10 with the highest signal strength is transmitted from the tablet 300 to the management server 500, the panel information 522 is acquired, and it is displayed as panel information 324. The operator refers to the panel information 324 on this tablet 300, that is, the room number, left or right hand, panel part number, placement location within the room, etc., and performs the construction of the panel 10 based on this information. Note that the panel information 324 may be displayed in the order of the signal strength of reading the RFID tags 100 of multiple panels 10, and the panel 10 with the UID displayed at the topmost position may be selected, or the UID with the highest signal strength may be highlighted by flashing, coloring, etc.

[0019] Similarly, for the second, third, and other stacked panels 10, when the same operation is performed, this time the signal strength of the RFID tag 100 of the second panel 10 is the strongest, so the panel information 522 is acquired from the management server 500 and construction is performed. In this way, even if the panels 10 are stacked, since the panel 10 at the topmost position is taken out and construction is carried out, construction can be accurately performed without making a mistake in the construction location, and the work efficiency can be improved.

[0020] Next, the case of distributing the carried-in panels 10 to each room where construction is to be performed will be described. (1) Read all the RFID tags 100 of the panels 10 with the tag reader 200 (step S56) (2) Display the panel information corresponding to the UID of the read RFID tag 100 (step S58) (3) Check whether a predetermined number of panels 10 have been carried into each room (step S60) (4) Search for the misdistributed panels 10 (step S62)

[0021] In this case, for all the panels 10 carried into the room, it is necessary to obtain panel information. Therefore, regardless of the signal strength, the tag reader 200 reads the RFID tags 100 of all the panels 10, receives the corresponding panel information 522 from the management server 500, and displays it as panel information 324 on the tablet 300. In addition, since the panel information of all the panels 10 has been obtained, for example, when the UID of the panel 10 required by the operator is known, the corresponding panel 10 can be searched for, and its building material information can be displayed on the tablet 300 or notified by sound or the like. Note that the information of the panel 10 that should originally be distributed can be obtained from the management server 500, and this can be compared with the detection result by the RFID tag 100 to detect distribution errors.

[0022] As described above, according to this embodiment, the RFID tag 100 is attached to the core material 12 of the panel 10 of the flashing material, and the panel information such as the shape of the panel 10 is stored in the management server 500 and read out and sent to the manufacturing factory or the assembly site. Therefore, the following effects can be obtained. a. By obtaining panel information using the RFID tag 100 of the panel 10, the types of the panels 10 can be easily distinguished during manufacturing and construction, and the work efficiency can be improved. b. At the assembly site, among the many stacked panels 10, the type of the topmost panel 10 can be known from the signal strength of the RFID tag 100, and the construction efficiency can be improved. c. The type of the panel 10 can be known using the RFID tag 100, and construction errors such as using panels 10 of different types by mistake can be reduced.

[0023] <Other Embodiments> Note that the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the gist of the present invention. For example, the following are also included. (1) The shapes, dimensions, and materials of the respective parts shown in the above embodiments are examples, and the design can be changed so as to achieve the same functions. (2) In the above embodiment, when the RFID tag 100 of the panel 10 is read by the tag reader 200, the ID of the operator (for example, the barcode that identifies the operator displayed on the name tag) may be read and transmitted to the management server 500, and the operator information may be added to the panel information 522. (3) The panel management application 310 of the tablet 300 shown in the above embodiment may be configured separately for use in a manufacturing factory and a construction site. (4) In the above embodiment, a database 520 is provided in the management server 500, but it may be provided separately. The management server 500 may be shared with a server used for other inventory management or the like. (5) In the above embodiment, the panel information 522 is displayed on the tablet 300, but various portable information terminals such as smartphones may be used. Also, the tag reader and the portable information terminal may be integrated. (6) Although the present invention is a preferred example of a flashing material, it does not prevent its application to other building materials.
