Description

  The present invention relates to a pre-cut processing system for residential timber, 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, and automates inspection work. It relates to a system that makes it possible.

  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). In the precut company B to which the raw material wood has been delivered, the wood cutting operation (step b6) is performed, the precut processing including the length cutting processing is performed in the precut equipment 2 (step b7), the inspection, packaging, Storage is performed (step b8), and the product is shipped and delivered 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. In addition, the processing of wood is performed only by the precutting facility 2 of the precutting company B, and the management of the stock of raw material timber is performed by 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 as described above, when the precut company B purchases raw material timber from the wood sales company C, it is usually purchased for each bundle of bundles in order to reduce the timber price. It is 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 above-mentioned unused timber has an inventory loss at a certain rate, and there is also a problem that a timber storage, or costs and interest charges related thereto are also generated.

  In the pre-cut company B, it is considered that when pre-cut processing is usually performed, the yield is increased as much as possible by allocating wood according to how the pre-cut product is taken from the raw material wood. However, as described above, in order to reduce the occurrence of unused inventory, it was impossible to hold abundant types, and it was necessary to select wood appropriately from a small number of options. Furthermore, there is a problem that the yield does not increase because it is difficult to allocate trees in multiple buildings.

  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.

  Moreover, in the precut company B, the raw material lumber used for precut processing from the said bundle is carried out. 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, it was necessary to bear the expense concerning picking work. 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.

  An object of the present invention is to solve the above-mentioned problems, rationalize inventory management work in order to reduce inventory, improve yield, prevent shortage, and level pre-cut operation.

  The pre-cut processing system of the present invention is equipped with a length cutting device attached to an automatic warehouse, cuts the raw material wood into a desired length by the length cutting device, and supplies the semi-finished product to the pre-cut processing facility. This is a system for processing products by applying pre-cut processing, in combination with data obtained from authentication tags attached to wood and processing data given to length cutting devices and pre-cut processing equipment, cutting processing and pre-cut processing It is characterized by doing.

Moreover, the said length cutting process performs the wood allocation allocation with a sufficient yield by combining the semi-finished product supplied to several precut processing equipment, and cutting raw material wood.

  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.

  The first authentication tag among the authentication tags is attached to the end face of the raw material wood, separated from the semi-finished product at the time of length cutting, and collected as necessary. The second authentication tag is the semi-finished product. A position that does not interfere with the part to be cut by the pre-cut machining is detected from the machining data and attached to a position that does not interfere.

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

Further, the second authentication tag has data for specifying a semi-finished product and data for specifying a product, and after completion of the cutting process, the second authentication tag includes data of a desired semi-finished product obtained by checking with the first reader. Based on the data of the desired product obtained by checking with the second reader 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 that are delivered to the construction site, packed and automatically inspected.

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

In addition, when cutting the length, the wood sales company can allocate the wood, so that the choice of wood 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 wood used is reduced, and the total amount of wood cutting and length cutting processing is also reduced by that amount, so that productivity can be improved.

  In addition, by performing the length cutting process at the wood sales company as described above, the wood sales company generates a work for timbering and length cutting processing for the processed semi-finished product.

In addition, with regard to the work, an automatic warehouse is introduced by using the authentication tag that has been input data, and the benefits of scale can be obtained by summarizing the work that has been carried out at each pre-cut company in the past, thereby streamlining the work as a whole pre-cut processing system. it can.

  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 authentication tag with the first reader attached to the picking crane installed in the automatic warehouse. Similarly, by using an authentication tag, inspection at the time of shipment can be automated, and a shortage can be prevented.

Similarly, even if there is a problem with the material tracking of the pre-cut processing equipment, recovery can be performed automatically, and moreover, when products are packed in a delivery unit, the products in the same package are collected at the packing location. It is possible to streamline the confirmation of the packing contents by automatically sorting and automatically transporting.

Also, by using an authentication tag, it is possible to easily instruct reassignment of the corresponding raw material wood when a raw material defect is detected, and the raw material wood necessary to make the corresponding product even when a defective product of a semi-finished product is detected Can be easily allocated.

  In the precut processing system of the present invention, a length cutting device is attached to the automatic wood warehouse, and the length cutting is performed in the automatic wood warehouse. In this way, the wood that is delivered to the precut company from the wood sales company by cutting the length in the automatic wood warehouse, all the quantity, tree species, properties (cross-sectional shape, grade), etc. necessary for the production of precut products A semi-finished product with the length cut into the product length. In pre-cut processing equipment, pre-cut processing is applied to semi-finished products to make pre-cut products. The length cutting process and the precut process are performed based on electronic data obtained from an authentication tag attached to the 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 house maker or the like orders a precut product from a precut company, a lumber sales company delivers a semi-finished product obtained by picking and cutting the length of the wood to the precut company based on electronic data relating to the ordered product. The pre-cut company applies pre-cut processing to semi-finished products based on electronic data, and delivers pre-cut products to construction sites managed by housing manufacturers. All electronic data from the authentication tag attached to the pre-cut 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 makes it possible to easily confirm the processing, product specifications, delivery date, etc. at the processing site, construction site, etc., and to input electronic data into the company database. In particular, by installing a wood automatic warehouse, automatic processing equipment, etc., it is possible to automate all of the tree-making, length cutting processing, pre-cut processing, inspection, packing, and storage based on the data.

  FIG. 1 is a block diagram showing a precut processing 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), Inspection of pre-cut products (step d2) is performed.

In the present embodiment, product warehouses 14 and 15 are provided for temporarily storing precut products subjected to precut processing. 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 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 wood suitable for precut processing from the 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. . The computers COM1 to COM5 are input with data such as product data, delivery, and shipping status.

  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 of H (height), L (length), and price is written and held in advance. The second authentication tag T2 is attached to the wood that has been subjected to the length cutting process, and the manufacturer, date of manufacture, tree species, W (width), H (height) for identifying the semi-finished product and the product. , L (length), price, house maker name, ridge name, part code, pre-cut processing location, processing date, and shipping date data are written and held.

  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 wood 20 that is the raw material wood. The wood 20 is initially processed to have a length of 10 to 20 mm at both ends and the length after the cutting as a product length in order to obtain a rectangular shape at the end. For this reason, in this 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 first reader in the length cutting device, and the length At the time of cutting, the end 20a of the wood 20 is cut off from the cutting position 21 together with the first authentication tag T1 in cooperation with the cutting data given to the length cutting device, and the first authentication tag T1 is used as necessary. Collected.

The second authentication tag T2 can be attached before or after the cutting of the wood, and after the cutting, the second authentication tag T2 is attached so as to remove the processing site from the side of the wood pieces 25 to 27 which are cut into lengths and become semi-finished products. It is done. Before the cutting, the second authentication tag T2 is attached so as to remove the cut positions 22 to 24 and the processing site. This second authentication tag T2 holds data for specifying a semi-finished product obtained by checking with the second reader in the precut processing facility, and cooperates with the data and the processing data given to the precut processing facility. Process semi-finished products. 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 wood piece 28 is a portion discarded as an unused member. 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.

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 2 surface directions, and it can make it easy to check with a 2nd reader. .

  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 relating to the flow of wood, ordering, processing, and shipping in the precut processing system configured as described above will be described. First, if there is a request from a customer for housing construction in D1 and D2, etc., these housing manufacturers D1 and D2 input CAD for precut companies E1 and E2 to process precut products according to the drawings of the house. 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 pre-cut companies E1 and E2 send data related to wood as a raw material according to the 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 the first reader and input to the computer COM5 as inventory management data. The end portion of the selected wood is cut off as described above, and at that time, the first authentication tag T1 is collected as necessary, and is cut into a length based on the data by the length cutting device 17. (Step f2). 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 wood selection and length cutting process not only orders from the precut company E1, but also all orders from other precut companies E2, etc., so that the amount of wood pieces to be discarded is minimized. Selection and processing are performed in combination so that products of the required length can be obtained efficiently. The 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 by the automatic packing facility 18 in a packing unit that is checked by the first reader and delivered to the precut facility. Then, they are shipped to the precut companies E1 and E2 (step f3). At the time of shipment or packing, the second authentication tag T2 is checked by the first reader, and the shipment and the data of 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 are compared with the product data obtained by checking the second authentication tag T2 with the second reader. Then, based on the product data required for construction, the wood is pre-cut. The pre-cut wood is temporarily stored in the product warehouses 14 and 15 until it is collected for each building site based on the corresponding data required at the building sites 10 and 11, for example, and corresponds to the building sites 10 and 11. The products to be delivered are packed together in packing units to be delivered (step e2), and shipped to the construction sites 10 and 11 managed by the housing manufacturers D1 and D2 (step e3). Further, at the time of shipment, the second authentication tag T2 is checked by the second reader 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).

  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 is sent from the precut companies E1 and E2 to the construction sites 10 and 11 without any delay, and can be manufactured and shipped extremely efficiently. Moreover, although the wood sales company F requires the length cutting processing equipment 17, it can reduce the waste amount of wood and can use it effectively, 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, so that shortage can be reduced, and returns, exchanges, and the like can be performed smoothly.

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 according to the present invention reduces the stock and loss of each pre-cut company by cutting the length at a wood sales company, and uses the authentication tag to facilitate the inspection work at the time of packing. It is streamlined and enables 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.
