Description

  The present invention relates to a structure for attaching an authentication tag for wood used for, for example, management of raw material wood for residential wood or wood products to be precut.

  FIG. 8 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.

  The timber is transported 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 products required at a construction site, for example, one house, are collectively carried in, processed, and transported. 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 the products by checking the wood products manually, However, there was a problem that it was very complicated and time-consuming.

  Therefore, the present applicant has proposed the technique described in Patent Document 1 as a system for managing wood using the Internet or online. 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, the timber is stacked and pre-cut by the pre-cutting company in advance to the desired size and shape used for the building. Pre-cutting such as cutting is applied, so simply attaching the recognition tag to the surface of the timber will result in overlapping timber. There was a possibility that the problem of being damaged or peeling off by rubbing in the case may occur. Therefore, as described in Patent Document 2, the applicant of the present application has proposed a recognition tag mounting structure that can prevent the recognition IC tag from being peeled off and can easily input and read data by checking the mounting position. In this mounting structure, a method is adopted in which the recognition tag is firmly fixed with an adhesive at the mounting position where the recess is formed in the wood product, and the recognition tag is protected from damage.

  Although the technology described in Patent Document 2 can reuse the recognition tag, basically, the recognition tag is left as it is without being easily peeled off from the wood product.

  The present invention can easily attach and remove the recognition tag of this type, can be reused after being removed, and can easily input the data of raw material wood or wood products by checking the position after the attachment. A structure for attaching a recognition tag for wood that enables reading is provided.

  The structure for attaching the recognition tag for wood according to the present invention inputs the wood recognition information of the raw material wood between the end face of the wood obtained by cutting the raw material wood into a desired length or between the end of the mouth end processed from the end of the mouth and the side face of the end of the mouth. The first recognition tag is removably attached, and the end of the wood including the first recognition tag is cut to form an end face perpendicular to the longitudinal direction, and then the first recognition tag is mounted. The second recognition tag is inputted by removing and collecting the other wood recognition information or product recognition information of the wood product after the precut processing, and the second recognition tag is located at a position that does not interfere with the precut cutting site when the wood is precut. A recognition tag is attached.

  The first and second recognition tags are covered with a non-contact IC chip that holds the recognition information and a anteflexible insulating material that inputs and outputs the recognition information. It has a fixing part which engages.

  The first and second recognition tags are thin plate-shaped and rectangular, the fixing portions at both ends are cut, and the fixing member uses a staple.

  In addition, the first and second recognition tags are provided with a protrusion in the vicinity of the inside of the fixed portion.

  In addition, the wood recognition information of the first recognition tag includes the origin, manufacturer, date of manufacture, tree type, grade, W (width), H (height), L (length), and price of the raw material wood. The product recognition information of the second recognition tag includes manufacturer, date of manufacture, tree species, grade, W (width), H (height), L (length), and housing manufacturer Name, building name, part code, pre-cut processing place, scheduled processing date, processing content, processing end date, scheduled shipping date, manual processing, assembly procedure, and price data. These data are written, deleted or rewritten as appropriate. Held

  According to the present invention, since the recognition tag can be reused many times, the wood product does not become expensive and is efficient.

  Further, by fixing the fixing portion at the end of the authentication tag using a fixing member that can be easily removed, the IC tag and the antenna can be removed without damaging them, so that the recognition tag can be reused.

  In addition, since the protrusion is provided in the vicinity of the fixed portion of the recognition tag, there is a margin for a slight gap between the recognition tag and the surface of the wood product, so that the surface of the flexible material covering the IC chip is damaged. This makes it difficult to input and read data.

It is a perspective view which shows the attachment structure of the authentication tag for wood which concerns on one Example of this invention. It is a perspective view which shows an IC tag. 1 is a perspective view showing a state where an IC tag is attached to a wood 10. It is a perspective view which shows the state which attached the 2nd IC tag to the timber. It is a top view which shows the example of a change of IC tag from which an external shape differs. It is a top view which shows the example of a change of the fixing | fixed part of an IC tag. It is a perspective view of the one end part which shows the modification of an IC tag. It is a block diagram which shows the flows, such as processing of conventional general precut products, and shipment.

  The recognition tag in the mounting structure of the authentication tag for wood according to the present invention uses an IC tag, and is attached to a wood product obtained by pre-cut processing to a desired size and shape to be used as an assembly material of wood and building materials obtained by cutting raw material wood into a desired length. It is done. The IC tag attached to the wood is detachably attached to one end surface or both end surfaces of the wood as the first IC tag, or between the end of the mouth end to the end surface of the end of the mouth. The IC tag attached to the wood product is re-input to the first IC tag removed after cutting the end of the wood to make the second IC tag, and at the position where it does not interfere with the precut cutting site when precutting. Attached.

  As described above, since the first IC tag removed from the wood is reused as the second IC tag, the IC tag can be used efficiently and an increase in the price of the wood product can be suppressed.

  In addition, since the IC tag is used several times after rewriting data, an IC chip with a small capacity can be used, and the IC chip can be small and simple and inexpensive.

  FIG. 1 is a perspective view showing a structure for attaching a recognition tag for wood according to an embodiment of the present invention. The wood 10 is in a state as a raw material wood, and is cut into a predetermined length according to several standards, for example, 30 × 30 × 200 cm, and the cross-section 101 has a square shape. The wood 10 is in a state before being subjected to precut processing such as cutting and cutting. A first IC tag 11 as a first recognition tag is attached to one end surface 101 of the wood 10. The end face 101 of the wood 10 is not easily rubbed even when other woods are stacked, and does not touch the processing table of the processing machine. Therefore, the first IC tag 11 is not damaged or dropped off. is there.

  In the present embodiment, the first IC tag 11 is attached to one end face 101 of the wood 10, but if the end face 101 of the wood is rough or not flat, the first IC tag 11 is attached. As shown by the dotted line in FIG. 1, the first IC tag 11 is attached to L between the end of the end that is a cut surface and the side surface of the end of the end of the end.

  FIG. 2 is a perspective view showing the first IC tag. The first IC tag 11 is a thin sheet-like flexible substrate 13 provided with a pattern of an antenna 12 for transmission and reception, and an IC chip 14 mounted on the flexible substrate 13 is thinly covered with a flexible insulating material. Thus, a rectangular plate shape is formed so that the IC chip 14 is located at the center. Both ends of the first IC tag 11 are provided with notches 15 as fixing portions for engaging fixing members such as metal or resin needles, scissors, and staples.

  FIG. 3 is a perspective view showing a state in which the first IC tag 11 is attached to the wood 10. A notch 15 at the end of the first IC tag 11 is engaged with a metal staple 16 having a U-shape and driven into the wood 10 with a staple driving machine. The first IC tag 11 is cut into the wood 10. Fixed. The staple 16 driven into the wood 10 can be easily removed with a tool such as a remover.

  The IC chip 14 of the first IC tag 11 attached to the wood 10 has a production area, a manufacturer, a production date, a tree species, a grade, W (width), H (height), L, which specify raw material wood as recognition information. Data such as (length) and price are input via the antenna 12 and used for management of storage, shipment, processing, and the like of the wood 10. That is, the wood 10 to which the first IC tag 11 is attached is prepared in a separate reader / writer that can read the recognition information in a non-contact manner when being transported or carried in, and is held in the first IC tag 11. By reading the data, the state of the wood 10 can be easily grasped and managed.

  The wood 10 with the first IC tag 11 fixed to the end face 101 is cut as shown in the dashed line in FIG. And the end portion 102 including the first IC tag 11 is separated. From the separated end 102, the first IC tag 11 is removed and collected using a tool such as a remover at a fixed timing, and the first IC tag 11 that has been collected has already been input. The data used as the wood recognition information is deleted, and another piece of wood recognition information or product recognition information of a pre-cut wood product is input and reused as a second IC tag as a second recognition tag.

  FIG. 4 is a perspective view showing a state in which the second IC tag is attached to the semi-finished wood product. The second IC tag 17 includes the manufacturer, date of manufacture, tree species, grade, W (width), H (height), L (length), price, house maker, etc., that identifies the wood product as product recognition information. Data such as name, building name, part code, pre-cut processing location, scheduled processing date, processing content, processing end date, scheduled shipping date, manual processing, assembly procedure, and use of structural reinforcement metal fittings are appropriately written and held. Since the wood semi-finished product 23 obtained by cutting the end portion 102 of the wood 10 is used as the wood products 18, 19, 20 after the precut processing, the second IC tag 17 has the precut cutting site 21, It is attached at a position where it does not interfere with 22. That is, the semi-finished wood product 23 whose end 102 has been cut is divided into a plurality of wood products 18, 19, 20 having a predetermined length to be used as an assembly material for a wooden building, and the kerfs 24, holes 25 Etc. are cut, and the second IC tag 17 is attached at a position away from the cutting parts 21 and 22 and the cutting part.

  The second IC tag 17 is fixed so as not to be easily peeled off, but may be detachably attached. Further, the second IC tag 17 is provided at a position where the second IC tags 17 do not overlap with each other when the wood products are accumulated, or at a position where the second IC tags 17 do not overlap each other.

  As a result, the second IC tag 17 can be visually confirmed between woods or from the side, the reader / writer can be used reliably, and data can be easily read.

  The second IC tag 17 is fixed to the flat portion (upper surface in FIG. 4) of the wood product 18, and the second IC tag 17 is fixed to the side surface (side surface in FIG. 4) of the wood product 19. As for the fixing method, both ends of the second IC tag 17 are fixed to the wood products 17 and 18 with a staple or a nail in the same manner as the first IC tag 11, but may be fixed with an adhesive. In addition, the second IC tag 17 can be used when the wood product 20 is stored and transported in a stacked manner by fixing the fixing part of the wood product 20 to a concave portion (upper surface in FIG. 4) of the flat portion. There is no risk of 17 being rubbed and damaged by other wood products. The concave portion is formed by performing a relatively easy process that is usually performed by a pre-cut process such as a recess process of about 1 to 2 mm or a cutting process of a depth of about 1 to 10 mm. It is formed so as to form a prism.

  The wood products 18, 19, 20 to which the second IC tag 17 is attached as described above are held in the second IC tag 17 by the reader / writer at the time of pre-cut processing, transport / carry-in, assembly, etc. By reading the collected data, it is possible to easily grasp and manage the state of the wood product and the wood product. 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 shape of the first and second IC tags, the shape of the fixing portion, and the fixing method will be described. Since the first and second IC tags have the same form, they will be described here as IC tags.

  FIG. 5 shows a modified example of an IC tag having a different outer shape, in which the shape of the flexible insulating material covering the IC chip 26 and the antenna 27 is formed in a square shape, and the antenna 27 is made longer by reducing the size. Fixed portions provided at both ends of the IC tag have notches 31.

  FIG. 6 shows a modified example of the fixing portion of the IC tag, and has a simple fixing structure in which holes 28 for inserting nail-like fixing members are provided at both ends.

  As another modification of the fixing part of the IC tag, although not shown, a large hole or notch for inserting the bag can be provided.

  FIG. 7 is a partial perspective view showing a state in which a protrusion is provided at one end of the IC tag, and a pyramidal protrusion 30 is provided near the inside of the fixing portion 29 provided at the end. The protrusions 30 are provided at both ends of the IC tag, and are configured to prevent the entire surface of the IC tag from coming into contact with the wood product when it is fixed to the wood product, so that there is a gap between the wood product. This makes it difficult to scratch the surface of the IC chip and ensures reading of information on the IC chip.

  Although the protrusion 30 provided at one end of the IC tag has a conical shape, the protrusion may be formed in a pyramid shape, a cylindrical shape, or a prism shape.

  The wood products 18, 19 and 20 have a predetermined length used as an assembly material for a wooden building, and their cross-sectional shapes may be triangular, polygonal, round, etc. You may attach a recognition tag by forming a recessed part in the shape wood, respectively.

  In the above-described embodiment, after the first IC tag is removed, the product recognition information of the pre-cut wood product is input and used as the second IC tag, but the wood recognition information of the raw material wood is used as the second IC tag. And may be reused in the same manner as the first IC tag.

  The wood in the present invention is mainly intended for attaching an authentication tag to wood used as an assembly material for residential buildings, but it is also applicable to wood used for furniture, structures, materials, etc. Can be attached.
