Description

  The present invention relates to a structure for attaching an authentication tag for wood used, for example, for precut processing management of residential wood.

  FIG. 13 is a block diagram showing a flow of processing, shipment, etc. of a conventional general precut product. In general, a housing maker or a construction company (hereinafter abbreviated as “house maker or the like”) A receives an order from a customer for housing construction and creates a drawing for housing construction. Pre-cut company B inputs CAD according to the house building drawing created by housing maker A (step b2), and pre-cut after housing maker A checks if the input data is desired for processing the product. Order a precut product from company B (step a1). In the pre-cut company B, after receiving an order (step b1), a tree allocation table, a tree chart and processing data are created based on the input data, and a production plan is drafted (production management) (step b3). Here, the raw material wood (raw material) necessary for processing the precut product is ordered from the wood sales company C (step b4). Inventory and warehouse management (inventory management) are performed as necessary (step b5). In the wood sales company C, the designated wood is selected by receiving an order for raw material wood (step c1) and delivered from the wood warehouse 1 of the wood sales company C to the precut company B (step c2). In the precut company B to which the raw material wood has been delivered, the tree cutting operation (step b6) is performed, and precut processing including length cutting is performed in the precut equipment 2 to obtain a precut product (step b7), and inspection, packing, and storage are performed. (Step b8), the product is shipped and delivered to the construction site 3 of the housing manufacturer A (step b9). The pre-cut product is accepted at the construction site 3 (step a2).

  As described above, the ordering of the timber is performed in the order of the house maker A, the precut company B, and the timber sales company C, and the timber is delivered in the order of the timber sales company C, the precut company B, and the house maker A. In addition, wood processing is performed by the precut equipment 2 of the precut company B, and management of stock of raw material wood is performed by the precut company B and the wood sales company C, respectively. In particular, there are multiple housing manufacturers A, pre-cut companies B, and wood sales companies C, and the relationship between each company (raw material ordering, raw material delivery, pre-cut product ordering, pre-cut product delivery, etc.) depends on the number of each company. Furthermore, the construction site is managed for each property.

  As described above, timber is carried and transported between the timber sales company C, the precut company B, and the housing maker A, and is individually managed and processed at each company or construction site. In general, wood required for a construction site, for example, one house, is carried in, processed and transported together. For this reason, the items to be managed were diverse and it was necessary to manage each company and each site. However, since the workers managed by checking the wood manually, There was a problem that it was very complicated and time-consuming.

  A system for managing wood using the Internet or online has been proposed by the present applicant (Japanese Patent Application No. 2006-135830). In this system, an authentication tag such as an IC tag is used for inputting and reading data, and it has been confirmed that management work is simplified by using the authentication tag. However, since the surface of the wood is standing upright or dust, dust, etc. are attached, it may be peeled off even if a sheet-like authentication tag is attached. In addition, since wood is stacked and processed such as cutting and cutting, simply attaching it to the surface of the IC tag and the wood makes it impossible to know the position of the authentication tag with the overlapped wood, or it is rubbed and damaged or peeled off. The occurrence of the problem was predicted.

  The problem to be solved by the present invention is to attach an authentication tag for wood that prevents the occurrence of the above problems, withstands accumulation, movement, and processing, and clearly confirms the position so that data can be easily input and read. To provide a structure.

  In the structure for attaching an authentication tag for wood according to the present invention, the concave portion provided in the wood having a predetermined length is in a position where the wood does not overlap when the wood is accumulated, and the authentication tag is attached in the concave portion. The concave portion in the attachment structure of the authentication tag for wood is provided at a position where it does not interfere with a portion of the wood to be cut. Moreover, the said recessed part consists of one or the combination of the recessed part formed in the plane part of the said timber, the recessed part formed in the corner | angular part of the said timber, and the recessed part formed in the cutting | disconnection end surface of the said timber. Moreover, the shape of the internal space of the recess is any one of a prism, a triangle, a cylinder, a semi-cylinder, and an elliptic cylinder. The authentication tag is fixed to the inner surface of the concave portion with an adhesive. The authentication tag is formed by embedding an IC chip in an elastic material, and is attached in the concave portion by the elasticity of the elastic material. The authentication tag is housed in the concave portion and attached by closing the opening of the concave portion with a plug-like member. Moreover, the said authentication tag is stored in the said recessed part, and is attached by spraying an adhesive agent on the said authentication tag. The adhesive or plug-like member is colored.

  According to the present invention, the concave portion provided in the wood having a predetermined length is in a position that does not overlap when the wood is accumulated, and the authentication tag is attached therein, so that the wood having a rough surface before processing Even if an authentication tag is attached to the, it will not be easily peeled off or rubbed by overlapping wood. In particular, when not only the flat part of wood but also concave parts in the corners and cut end faces, the cross-sectional shape is not only rectangular, but also wood that is round, triangular, or polygonal. The authentication tag can be attached at a position where it can be easily confirmed.

  Further, when the authentication tag is fixed with the adhesive, the concave portion is provided, so that the adhesive does not flow out from the bonding position, and the authentication tag can be firmly attached without waste. In addition, the concave part is formed in a hole shape whose inner space shape is a cylinder or the like, and an authentication tag in which an IC chip is embedded in an elastic material is housed therein, so that authentication can be performed without using an adhesive. A tag can be attached.

  Moreover, after storing an authentication tag in a concave part, the authentication tag can be reliably attached to wood by closing the opening part of a concave part with a plug-shaped member.

  Moreover, it can also adhere to wood by spraying and coating an adhesive on the authentication tag housed in the concave portion, and the position of the authentication tag can be shown more clearly by coloring the adhesive.

  The authentication tag in the structure for attaching an authentication tag for wood according to the present invention is attached in a concave portion provided in wood having a predetermined length used as an assembly material for a building. The concave portion is provided at a position where the concave portions do not overlap with each other when the timber is accumulated, and includes, for example, a concave portion formed on a flat portion of wood, a corner or corner portion of the flat portion, a cut end surface, or the like. The authentication tag is attached by being adhered to the inner surface of the concave portion or being pushed into the concave portion. Further, the authentication tag is more securely attached by blowing the adhesive or plugging the opening of the concave portion with a plug-like member.

  As mentioned above, since the authentication tag attached in the concave part of the wood does not touch the wood directly or the processing table of the processing machine, even if the wood is stacked, cut, or cut, It will not drop out or be damaged. In addition, the concave portions provided on the corners and cut end faces of the wood can be visually confirmed between the woods or from the side even if the woods are stacked, and the positions thereof can be easily confirmed.

  FIG. 1 is a perspective view showing an attachment structure of an authentication tag for wood according to an embodiment of the present invention. The wood 10 is in a state as a raw material, and is in a state before being subjected to processing such as cutting and cutting. In the case of the wood 10 as such a raw material, in order to divide into a plurality of semi-finished products of a predetermined length to be used as an assembly material of a wooden building or to obtain a rectangular end portion, at the cutting parts 11, 12, 13 A pre-cut cutting process is performed. The recesses 14, 15, 16 are formed at such positions that do not interfere with the cut portions 11, 12, 13 by performing recess processing or the like.

  The recesses 14 and 15 are formed in a flat portion (upper surface in FIG. 1) of the wood 10, and the recess 16 is formed in a cut end surface (left end surface in FIG. 1) of the wood 10. The recesses 14, 15, and 16 are formed by performing relatively easy processing that is usually performed in precut processing such as recess processing of about 1 to 2 mm or cutting processing of a depth of about 1 to 10 mm. . The recesses 14, 15, and 16 are formed so that the shape of the internal space forms a quadrangular prism.

  The recesses 14, 15, 16 formed in this way are in a state in which the inner surfaces are smooth and dirt and dust are removed. An IC tag 17 as an authentication tag is attached to the bottom of each of the recesses 14, 15 and 16. As shown in FIG. 2, the IC tag 17 is composed of a thin sheet-like flexible substrate 18 provided with a transmission / reception antenna pattern, and an IC chip 19 mounted on the flexible substrate 18. The IC tag 17 specifies the manufacturer, date of manufacture, tree species, grade, W (width), H (height), L (length), price, etc., semi-finished products and products that specify the raw material wood. Manufacturer, date of manufacture, tree species, W (width), H (height), L (length), price, name of house maker, building name, part code, pre-cut processing place, scheduled processing date, processing details, processing Data such as end, scheduled shipping date, manual processing, assembly procedure, use of structural reinforcing metal fittings, etc. are written or rewritten as appropriate.

  As described above, the wood 10 with the IC tag 17 mounted in the recesses 14, 15 and 16 has the data held in the IC tag 17 by the reader / writer at the time of transportation / carrying in, precut processing, assembly, etc. By reading, the state of the wood 10 and its product can be easily grasped and managed. Note that writing and reading of data can be automated by installing a reader / writer in a transfer device or processing machine.

  Next, an example of changing the formation position and the shape of the recess will be described. FIG. 3 is a perspective view showing a state in which the recesses 20, 21 and 22 are provided at the corners of the wood 10 having a rectangular cross section. The recesses 20, 21, and 22 have a quadrangular prism, a substantially half cylinder (half cylinder), and a triangular cylinder, respectively. The recesses 20, 21, and 22 are in an open state in two directions, upper and front, in FIG. When attached to the recess 20, the IC tag 17 is attached to the bottom surface 20a or the side surface 20b. When attached to the recess 21, the IC tag 17 is attached to the side surface 21a composed of a flat surface. It is done. Thus, if the recessed part 20,21,22 is provided in the corner | angular part of the timber 10, since two directions are opened, there exists an advantage that it becomes easy to find the position of the recessed part 20,21,22 even if it piles up timber.

  4 to 6 are perspective views showing a state in which the recesses 24, 26, 28, and 29 are formed in the woods 23, 25, and 27 whose cross-sectional shapes are triangular, polygonal, round, or the like. As shown in the figure, the timbers 23, 25, and 27 have a predetermined length used as an assembly material of a wooden building, for example. Concave portions 24, 26, 28, and 29 can be formed on the curved surface portion.

  Further, as shown in FIG. 7, it is also possible to use a hole whose inner space forms a cylinder as the recess 30. The concave portion 30 is formed by performing relatively easy processing that is usually performed by precut processing such as boring hole processing of about 10 to 20 mm. As described above, the recesses can be provided in various places, but it is desirable to provide them on the cut end surface of the wood called a fore edge, which has the least influence on processing and is a position where the woods are difficult to overlap.

  Next, a configuration for ensuring the attachment of the IC tag will be described. FIG. 8 is a cross-sectional view showing a structure in which the IC tag 17 is fixed in the recess 32 using the adhesive 31. The adhesive 31 is applied so as to be interposed between the bottom surface of the recess 32 and the IC tag 17. FIG. 9 is a cross-sectional view showing a structure in which the adhesive 33 is sprayed onto the IC tag 17 and fixed in the recess 32. The adhesive 33 may be in the form of a resin, covers the surface of the IC tag 17 so as to coat it, and fixes the IC tag 17.

  FIG. 10 is a cross-sectional view showing a structure in which the IC tag 34 is bent and inserted into the hole-shaped recess 30 shown in FIG. As shown in FIG. 12, the IC tag 34 is configured by embedding an IC chip 36 in an elastic material 35 such as a rubber sheet or a resin sheet. As shown in FIG. 7, when the IC tag 34 is bent into a cylindrical shape and pushed into the recess 30, the elastic material 35 spreads in the recess 30 and closely contacts the inner surface of the recess 30, and the IC tag 34 is fixed. As described above, the IC tag 34 can be mounted in the recess 30 without using an adhesive. Further, even if the IC tag 17 does not use the elastic material 34, as shown in FIG. 11, after being accommodated in the concave portion 30, the opening portion of the concave portion 30 is formed in a plug shape made of resin, adhesive, wood or the like. It can be held in the recess 30 by closing with the member 37.

  Further, if the adhesive 33 or the plug-like member 37 is colored, the position of the IC tag 17 can be easily found, and workability can be improved. In particular, when the adhesive 33 is colored, the color can be visually recognized by the adhesive protruding around the IC tag 17 or by the adhesive coated by spraying, and the position of the IC tag 17 can be shown more clearly.
