Description

  The present invention relates to a pre-cut processing management system for residential wood, and in particular, reduces the stock of raw material wood for supply to pre-cut processing equipment, realizes a good yield as a whole pre-cut processing system, inspection, management, The present invention relates to a system capable of simplifying assembly work.

  FIG. 7 is a block diagram showing a flow of processing, shipping, etc. of a conventional precut product. In general, a housing maker or a construction company (hereinafter abbreviated as “housing maker”) A receives an order from a customer for housing construction and creates a drawing for housing construction. The pre-cut company B inputs the CAD according to the housing construction drawing created by the housing manufacturer A (step b2), and the housing manufacturer A confirms whether the input data for processing the product is desired. A precut product is ordered from the precut 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 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). At the precut company B to which the raw material wood has been delivered, the wood cutting operation (step b6) is performed, and the precut processing including the length cutting processing is performed in the precut equipment 2 to obtain a precut product (step b7). Perform (step b8), and ship and deliver to the construction site 3 of the house maker 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. Wood processing is performed at the precutting facility 2 of the precutting company B, and management of stock of raw material timber is performed at the precutting company B and the wood sales company C, respectively. In particular, there are multiple housing manufacturers A, pre-cut companies B, and timber 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 each company. Furthermore, the construction site is managed for each property.

  In the process related to the conventional precut processing management as described above, when the precut company B purchases raw material timber from the timber sales company C, in order to reduce the timber price, it is possible to purchase for each bundle that is a set of a plurality of bundles. Usually done. For this reason, the unused portion is in stock, and it is necessary for the precut company B to perform inventory management. In addition, the unused raw material timber as described above has a problem that inventory loss occurs at a certain rate, and there is also a problem of timber storage, or costs and interest burdens associated therewith.

  In addition, in the pre-cut company B, when pre-cut processing is usually performed, it is possible to increase the yield as much as possible by reducing the remaining material by allocating the wood to determine how to combine the semi-finished products to be pre-cut from the raw material wood. Be considered. However, as described above, in order to reduce the amount of unused inventory, it was impossible to hold abundant types, and it was necessary to select raw material wood appropriately from a small number of options. In addition, it is difficult to allocate wood in a plurality of buildings, and there is a problem that most of the remaining material after wood allocation and cutting is discarded, and the yield does not increase.

In addition, the pre-cut processing includes a part that cannot be automatically processed in addition to an automatic part that is automatically processed by a processing apparatus, and sometimes forgets manual processing. Normally, products that have undergone precut processing are packaged and delivered to the construction site. However, since checking the contents of the packaging is done through human work, there is also a problem that shortages are likely to occur. It was. In addition, at construction sites, experienced work managers check the excess or deficiency of products based on drawings, or perform assembly instructions by instructing manual processing parts processing and placing products in the right place. A skilled person was needed.

  Further, in the precut company B, the raw material lumber necessary for precut processing is performed from the bundle. It is necessary to perform this tree-making work by an operator or use an automatic warehouse that automatically performs picking based on processing data. For this reason, in the pre-cut company B, the expense concerning picking work was also borne. In addition, this picking work has a problem that, when the daily production amount varies, the operation rate is lowered and the operation time is prolonged.

  The problems of the present invention are to solve the above problems, streamline inventory management work to reduce inventory, improve processing yield by eliminating processing omissions, prevent shortage, and level pre-cut operations. It is to improve workability at the construction site.

  The pre-cut processing management system according to the present invention includes a length cutting device attached to an automatic warehouse, cuts the raw material wood into a desired length by the length cutting device, and turns the semi-finished product into a pre-cut processing facility. A system for processing a product by supplying and pre-cut processing, wherein the data obtained from the first authentication tag attached to the raw material wood and the data given to the length cutting device are processed in cooperation with the semi-finished product And the data obtained from the second authentication tag attached to the semi-finished product and the pre-cut processing equipment, rewriting the data of the first authentication tag attached to only the remaining material and managing the remaining material The product is processed in cooperation with the processing data given to the product to make a product, and the product is managed and assembled based on the data obtained from the second authentication tag.

In addition, the cooperative processing of the data obtained from the first authentication tag and the data given to the length cutting device is to process the raw material wood by combining semi-finished products supplied to a plurality of precut processing facilities. Thus, the cutting process is performed in which wood is allocated with a small yield and a good yield.

In addition, the pre-cut processing equipment is supplied with a necessary amount of the semi-finished product after the length cutting, and the stock management work is rationalized by reducing the stock of raw material wood in the automatic warehouse.

In addition, the first authentication tag is attached to the end face of the raw material wood and attached as it is to the remaining material after the length cutting process, and the second authentication tag is a part to be cut by a precut process of a semi-finished product. A position that does not interfere is detected from the machining data, and is attached to a position that does not interfere.

Further, the first authentication tag has data for specifying raw material wood obtained by checking with a reader / writer in the length cutting device, and the data and cutting processing data given to the length cutting device; The raw material wood is cut and processed in cooperation, and the second authentication tag has data for identifying the semi-finished product obtained by checking with the second reader / writer in the precut processing facility, and the data and the precut processing Pre-cuts semi-finished products in cooperation with the processing data given to the equipment.

Further, the second authentication tag inputs and holds processing and manual processing end data by the precut processing equipment after the processing.

Further, the length data in the data held in the first authentication tag attached to the remaining material is rewritten by the reader / writer to the length of the remaining material in the precut processing facility and discharged from the precut processing facility. The remaining material having a predetermined length or more is returned to the automatic warehouse and used as a semi-finished material, and the remaining material having a length less than the predetermined length is used as a recycled material other than the semi-finished product.

The second authentication tag holds data for specifying a semi-finished product and data for specifying a product. After the length cutting process is completed, the second authentication tag includes data of a desired semi-finished product obtained by checking with the reader / writer. Based on the data of the desired product obtained by checking with the second reader / writer after the pre-cut processing is completed after packing the semi-finished product into a packing unit to be delivered to the pre-cutting equipment, packing and automatic inspection. The products are packed into packing units to be delivered to the construction site, and packed and automatically inspected.

In addition, the second authentication tag attached to the product after the precut processing includes manual processing data of the product at the construction site obtained by checking with the second reader / writer, assembly procedure data, and use data of the structural reinforcing bracket. Possess.

  According to the present invention, by performing precut processing on a semi-finished product that has been subjected to length cutting processing of the raw material wood in advance, the precut company receives only the semi-finished product necessary for the corresponding precut processing and performs precut processing. Therefore, inventory management at a precut company can be eliminated.

In addition, by disclosing the inventory status in the automated warehouse, the timber sales company can manage inventory management, including ordering and delivery of timber associated with precut processing, so that it does not run out of stock to timber manufacturers. Can be streamlined.

  Further, since the pre-cut company purchases the semi-finished products necessary for the processing of all the products as described above and the stock is lost, the stock loss and the interest rate burden are eliminated, and the business can be reduced. In addition, since there is no stock, the space previously used as a timber storage area can be used for other purposes.

  In addition, since only the necessary semi-finished products are delivered to the precut company, the picking work selected in the precut company is eliminated.

Further, when cutting the length, the wood sales company can perform the wood allocation, so that the choice of raw material wood including the remaining material already in stock can be increased and the yield can be improved.
Thereby, the total amount of wood as a raw material can also be reduced. Further, as the yield is improved as described above, the amount of raw material timber to be used is reduced, and the total amount of timbering and length cutting is reduced by the reduced amount, so that productivity can be improved.

In addition, with regard to operations, the use of the first authentication tag that has been entered into the data has led to the introduction of an automated warehouse, and the recycle of the remaining material has been used to summarize the work that has been carried out at each pre-cut company in the past. As a whole, the pre-cut processing management system can streamline the work.

  In addition, by using an automated warehouse at a timber sales company and automating it, the inventory can be streamlined as compared with conventional precut companies. That is, the inventory can be automated by checking the first authentication tag with a reader / writer attached to a picking crane installed in an automatic warehouse.

In addition, by rewriting and using the data of the first authentication tag, even if a remaining material longer than a predetermined length that can be used is produced, it can be managed as a semi-finished material. Since it is used as a reusable material other than products, waste material can be reduced, and the remaining material can be effectively used for other purposes and waste is reduced. In addition, inspection at the time of shipment can be automated to prevent out-of-stock items.

Similarly, by using the second authentication tag, recovery can be automatically performed even if a failure occurs in the material tracking of the precut processing equipment. By checking this, there is no oversight of manual processing omission, and the final confirmation of processing omission can be made by checking the product before shipment based on the processing end data. Further, when products are packed in a delivery unit, it is possible to rationalize the confirmation of the packing contents by automatically sorting and automatically transporting the same packaged products to the packing place. In addition, products can be confirmed at the construction site, manual processing parts can be checked to prevent manual processing leakage, the assembly procedure can be easily understood, and the assembly work does not require skill, reducing the burden on the operator. .

In addition, by using the first and second authentication tags, it is possible to easily instruct reassignment of the corresponding raw material wood when a raw material wood defect is detected, and even when a defective product is detected, the corresponding product is made. It is easy to allocate the raw material wood required for

Further, by printing on the product based on the data of the second authentication tag, it is possible to visually confirm the shortage, and depending on the contents of printing such as the company name and brand, an advertising effect to consumers and outsiders is produced.

  In the precut processing management system of the present invention, a length cutting device is attached to an automatic wood warehouse, and the length of the raw material wood is cut in the automatic wood warehouse. In this way, by cutting the length of wood at the automatic warehouse, it becomes a semi-finished product and remaining material, and the raw material wood delivered from the wood sales company to the precut company is the quantity, tree species and properties necessary for the production of the precut product (Section shape, grade) etc. are all provided, and the length is cut into a product length. On the other hand, if the remaining material is longer than the predetermined length, it is stored in the wood sales company as other usable wood, and the remaining material shorter than the predetermined length is used as a recycled material. In pre-cut processing equipment, pre-cut processing is applied to semi-finished products so that there are no processing omissions. This length cutting processing, pre-cut processing, and management of semi-finished products, products, and remaining materials are performed based on electronic data obtained from an authentication tag attached to wood. In addition, only the necessary timber will be transferred to timber automatic warehouses of timber sales companies, precut processing equipment of precut companies, and construction sites such as housing manufacturers.

  That is, when a housing manufacturer orders a pre-cut product from a pre-cut company, a wood sales company delivers a semi-finished product that has been picked and cut into length to the pre-cut company based on the electronic data related to the ordered product. We also manage inventory of possible remaining materials. A precut company preprocesses semi-finished products based on electronic data, and delivers the products to building sites managed by housing manufacturers. All electronic data from the authentication tag attached to the product is entered into the company database, and the product and its current status are tracked. In addition, the authentication tag attached to the product enables easy confirmation of processing, product specifications, delivery date, inspection, etc. at the processing site, shipping site, construction site, etc., and enables electronic data to be entered into the company database. . In addition, at the construction site, product shortages and manual processing omissions can be confirmed, and the operator can easily assemble products without requiring skill. In particular, by installing an automatic timber warehouse, automatic processing equipment, etc., it is possible to automate all of the wood extraction, length cutting processing, precut processing, inspection, packing, storage, and management based on data.

  FIG. 1 is a block diagram showing a precut processing management system according to an embodiment of the present invention. D1 and D2 are housing makers or construction companies (hereinafter abbreviated as “housing makers, etc.”), respectively managing the construction sites 10 and 11 and placing orders for precut products subjected to precut processing (step d1), Product inspection (step d2), assembly (step d3), and the like are performed.

  E1 and E2 are precut companies, respectively, and are equipped with precut processing facilities 12 and 13. In the present embodiment, product warehouses 14 and 15 for temporarily storing pre-cut processed products are provided. In the precut companies E1 and E2, precut processing is performed by the precut processing facilities 12 and 13 (step e1), the products are packed for shipping (step e2), and the products are shipped to the housing manufacturers D1 and D2, respectively. (Step e3).

  F is a timber sales company, and includes a timber automatic warehouse 16 for timbering raw material timber and a length cutting device 17 for cutting the raw material timber. Further, the wood sales company F in the present embodiment includes an automatic packing facility 18 for packing at the time of shipment. This wood sales company F selects raw material wood suitable for precut processing from stock (step f1), performs only length cutting processing (step f2), and ships (step f3). .

  COM1 and COM2 are computers provided in the housing manufacturers D1 and D2, respectively. COM3 and COM4 are computers provided in the precut companies E1 and E2, respectively. COM5 is a computer provided in the wood sales company F. . In the computers COM1 to COM5, data such as processing end, product data, delivery, shipping status, manual processing, assembly procedure, and use of reinforcing metal fittings are input.

  T1 and T2 are first and second authentication tags of the IC tag. The first authentication tag T1 is attached to the end of the timber when the raw material timber enters the automatic timber warehouse 16, and the manufacturer, date of manufacture, tree type, grade, W (width), which specifies the raw material timber. Data such as H (height), L (length), and price is written and held in advance. Prior to cutting the length of the raw material wood, a few centimeters are cut from the end face in order to obtain a right angle face of the end face, and the first authentication tag is attached to the end face opposite to the cut face. The first and second authentication tags T1 and T2 are attached to the wood that has been subjected to length cutting, the second authentication tag is a semi-finished product to be precut, and the first authentication tag is It can be attached directly to the remaining material, excluding semi-finished products after length cutting. The second authentication tag T2 attached to the semi-finished product includes the manufacturer, date of manufacture, tree species, W (width), H (height), L (length), price, house maker, etc. for identifying the semi-finished product and the product. Data such as name, building name, part code, pre-cut processing location, scheduled processing date, processing content, processing end, scheduled shipping date, manual processing, assembly procedure, use of structural reinforcement brackets, etc. are written and held. The first authentication tag T1 attached to the remaining material is rewritten by the reader / writer to newly manufacture the data, manufacturer, date of manufacture, tree species, W (width), H (height), L (length), pre-cut processing place Data is retained.

  The first and second authentication tags T1 and T2 are attached at positions where the wood is not cut or processed. 2 to 6 are perspective views of the wood showing the authentication tag mounting position. As shown in FIG. 2, the first authentication tag T1 is attached to the end face 20a of the timber 20 that is the raw material timber that is not cut. The wood 20 is initially cut to about 1 cm at the end 21 opposite to the end face 20a in order to obtain the rectangular shape of the end, and the length from the cut face 20b after the cutting is cut into the product length. . For this reason, in the present embodiment, the wood 20 is selected from the first authentication tag T1 attached at the time of warehousing based on the data obtained by checking with the reader / writer in the length cutting device, and the length cutting process is performed. Sometimes, it is cut into a desired length from the cut surface 20b of the timber 20 in cooperation with the cutting data given to the length cutting device to form two semi-finished products.

The second authentication tag T2 can be attached to the semi-finished product before or after cutting the wood, and after the cutting, the processing site is provided on the side surfaces of the wood pieces 22 and 23, which are cut into lengths and become semi-finished products. It is attached to remove. Before the cutting, the second authentication tag T2 is attached so as to remove the cut positions 24 and 25 and the processing site. The second authentication tag T2 holds data for specifying a semi-finished product obtained by checking with the second reader / writer in the precut processing facility, and cooperates with the data and the processing data given to the precut processing facility. Semi-finished product is processed, and processing end data is input after processing. The mounting position of the second authentication tag T2 specifies a position that does not interfere with the part to be cut based on precut processing data provided in advance by the precut companies E1, E2, and the like. The remaining material 26 after cutting the wood pieces 22 and 23 is attached with the first authentication tag T1 as it is, and data such as length, processing date, processing place, etc. is newly rewritten by the reader / writer. If it is longer than the length, it is inventoried as a semi-finished material, and if the remaining material 26 is less than a predetermined length, it is used as a recycled material or discarded as a waste material. As shown in FIG. 2, the second authentication tag T2 may be attached to the surface of the wood 20 by bonding, screws, nails, or the like. However, the second authentication tag T2 is damaged during transportation work or on the processing machine. 3 to 6, a recess 29 is formed in the corner or surface of the wood 20, and the second authentication tag T <b> 2 is attached to the bottom or inner surface of the recess 29. May be.
In addition, when attachment of a 1st authentication tag supports a process and conveyance, an attachment place can be changed without restricting to the end surface 20a.

By attaching the second authentication tag T2 in the recess 29 as described above, it is possible to prevent the second authentication tag T2 from being damaged or detached even when the wood 20 is rotated. Moreover, when the 2nd authentication tag T2 is attached in the recessed part 29 provided in the corner | angular part, the 2nd authentication tag T2 can be read from two surface directions, and it can make it easy to check with a 2nd reader / writer. it can.

  The first and second authentication tags T1 and T2 can also be formed by printing directly on the surface of wood using a barcode. Also in this case, the concave portion 29 described above may be formed and printed therein.

  Next, the flow and input / output of data related to wood flow and ordering, processing, shipment, and assembly in the precut processing management system configured as described above will be described. First, when a customer requests a housing construction from D1 and D2, the housing manufacturers D1 and D2 input CAD to process the precut products according to the drawings of the houses. Then, it is confirmed whether the input data is desired, and wood precut products are ordered from the precut companies E1 and E2 (step d1). The data relating to the necessary precut products can also be transmitted and received between the computers COM1 and COM2 of the housing manufacturers D1 and D2 and the computers COM3 and COM4 of the precut companies E1 and E2 via the Internet. The precut companies E1 and E2 send data related to wood as a raw material according to CAD input to the wood sales company F. The necessary data can be transmitted to the computer COM 5 of the wood sales company F via the Internet.

  The timber sales company F selects timber at the automatic timber warehouse 16 based on the received data (step f1). At that time, the first authentication tag T1 attached to the wood at the time of warehousing is checked by a reader / writer and input to the computer COM5 as inventory management data. The selected wood is cut at the end as described above, and is cut into a length based on the data by the length cutting device 17 with reference to the cut surface (step f2). The remaining material after the length cutting process is attached with the first authentication tag as it is, and the length data is rewritten with a reader / writer, and those whose length is determined to be, for example, 1 m or more are stock-managed as usable wood The On the other hand, those less than 1 m are used as reusable materials such as pallets, building material chips, and plywood laminators. Any remaining material that cannot be reused is discarded. Here, the 2nd authentication tag T2 in which the data regarding a pre-cut product were written is each attached to the wood by which length cutting was carried out. The above-mentioned selection of wood and length cutting processing are necessary not only to place orders from the precut company E1, but also to order all from other precut companies E2, etc. to minimize the amount of remaining material. Selection and processing are performed in combination so that products of a proper length can be obtained efficiently. Wood as a semi-finished product that has been subjected to the necessary length cutting processing based on the processing data as described above is packed in a packing unit that is checked by a reader / writer and delivered to a pre-cut facility, and is packed by an automatic packing facility 18. Ship to pre-cut companies E1, E2 (step f3). At the time of shipment or packing, the second authentication tag T2 is checked with a reader / writer, and the data of the shipment and the corresponding product are input to the computer COM5. At this time, it can be transmitted to the computers COM3 and COM4 of the precut companies E1 and E2 via the Internet. In addition, management of entry / exit and stock can be easily managed by data obtained from the first authentication tag T1.

  When the pre-cut companies E1 and E2 receive the semi-finished products, the pre-cut processing based on the data is performed on the pre-cut processing facilities 12 and 13 based on the production plan (step e1). At that time, the precut product number and the corresponding processing data for each precut product input in advance to the precut processing facilities 12 and 13 and the product data obtained by checking the second authentication tag T2 with the second reader / writer are obtained. The semi-finished product is pre-cut based on the product data required for construction. The pre-cut processing is performed on an automatic processing portion based on processing data and a hand processing portion that cannot be automatically processed. After the pre-cut processing, the inspection device is used to check whether there is any forgotten processing or error in the processing site that requires manual processing, and processing end data is input to the second authentication tag. Pre-cut wood has been input by the second reader / writer into the second authentication tag T2 with data related to manual processing of products detected at the construction site, combination position, assembly procedure, and structural reinforcement bracket use data. For example, based on the data corresponding to the construction sites 10 and 11, the products are temporarily stored in the product warehouses 14 and 15 until they are collected in units of the construction sites, and the products corresponding to the construction sites 10 and 11 are collected into packing units. (Step e2) and shipped to the construction sites 10 and 11 managed by the housing manufacturers D1 and D2 (step e3). Also, at the time of shipment, the second authentication tag T2 is checked by the second reader / writer to automatically detect the product, and the shipment and the data of the corresponding product are input to the computers COM3 and COM4. At this time, it can also be transmitted to the computers COM1 and COM2 of the housing manufacturers D1 and D2 via the Internet network.

  At the construction sites 10 and 11 of the housing manufacturers D1 and D2, the second authentication tag T2 attached to the delivered precut product is checked with a reader and input to the computers COM1 and COM2. Whether or not it exists is checked and accepted (step d2). After acceptance inspection, the reader is checked again, and hand processing is performed based on the information related to hand processing held in the second authentication tag T2, and the use position of the combination position and the reinforcing bracket based on the assembly procedure information Assembling while confirming the assembly procedure (step d3).

  As described above, the ordered data and the data at the time of shipment of the semi-finished product or the pre-cut product are always collated, and the system is easy to detect a shortage or a defect. In particular, the timber shipped from the timber sales company F will be sent to the construction sites 10 and 11 from the precut companies E1 and E2 without delay as a product, and can be manufactured and shipped extremely efficiently. Become. Moreover, although the wood sales company F requires the length cutting processing equipment 17, it can reduce the amount of the remaining material of wood and can use wood efficiently and can improve shipping efficiency. In addition, the yield of the entire system is improved as compared with the conventional system. In addition, the pre-cut companies E1 and E2 are out of stock. In addition, shipments and product checks at each company can be easily performed using an authentication tag, and it is possible to reduce missing parts and smoothly perform returns, exchanges, etc. No need for workers.

Of course, the housing manufacturers and pre-cut companies mentioned above are not limited to two as in the embodiment, but can be implemented with three or more, and a length cutting device is installed at the same site as the automatic wood warehouse. If it is, it may not be the equipment of the wood sales company.
In addition, progress management such as production management can be rationalized by collectively managing electronic data obtained from the authentication tag and the obtained location data, and accounting processing can be rationalized by linking with accounting data. At this time, the data link may use the Internet.

  Inventory management is automatically performed by the first authentication tag attached before warehousing, and wood allocation is always set based on the current inventory. In other words, if for any reason a shortage is found in the stock of raw material wood and it is not in time for delivery, it is possible to allocate the best tree in the current stock.

  The system in the present invention reduces the stock and loss at each pre-cut company by length cutting at a wood sales company, eliminates processing errors by using an authentication tag, and performs inspection work at the time of packaging. It is easy to improve the workability at the construction site, streamline the whole, and enable accurate management. When the wood sales company and the pre-cut company belong to the same company, it is also possible to mutually input and output data using an in-house LAN or the like.
