Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material processing management system for accurately managing the flow of a material to be processed.

[0002]

2. Description of the Related Art When a contract is made for housing construction, a house maker designs a house and arranges materials necessary for the house construction. The arranged material is carried into a pre-cut factory and pre-cut processing is performed. The pre-cut material is transported to a residential construction site and used for construction work. In such a system, a sales department that receives an order for house construction, a factory department that precuts materials, and a construction department that actually performs house construction work may each employ independent profitability. In this case, the sales department arranges and purchases the material (wood) once at a predetermined partition price and then sells it to the factory department.
The process of repurchasing the pre-cut materials at the added amount of labor is performed.

[0003]

The above prior arts have the following problems to be solved. Even when materials are brought into the pre-cut factory, the materials may be stored in the factory for several months in order to perform pre-cut processing as the construction progresses. However, the market price of the material often fluctuates while the material is stored in the factory. If the partition price from the sales department to the factory department or the repurchase price from the construction department to the sales department fluctuates in accordance with the market price of the materials, the profits of the construction department fluctuate and management becomes unstable. For example, if the price of the material rises, the profit will increase because the repurchase price of the precut material will rise, but conversely, if the price of the material falls, the repurchase price of the material will fall below the partition price and the labor can be recovered. Disappears. Therefore, it is conceivable to adopt a method in which the sales department absorbs the price fluctuation of the material price, delivers the material to the factory department at a constant partition price as much as possible, and collects the precut material at a constant repurchase price.

However, if the factory department gives priority to the pursuit of profits and sells products processed using materials purchased at a lower price than the market price to other than the sales department, the sales department suffers considerable damage. In addition, when the market price is low, it is conceivable to purchase cheap materials, precut, and sell them to the sales department. In this case as well, there is damage to the sales department, and if materials other than the supplied materials are used, the quality of the materials cannot be controlled. This can be caused by administrative errors as well as by design. Since a plurality of pre-cut materials may be produced from one material, it is not easy to control which material is pre-cut. In addition, if such a situation occurs, it will break the mutual cooperation between the sales department and the factory department. Therefore, there is a need for a system that automatically manages the flow of materials in which all materials delivered from a sales department are repurchased by the sales department.

[0005]

The present invention employs the following structure to solve the above problems. <Structure 1> This is a system for managing the material delivered from the requesting department to the processing department in the processing department and returning it to the requesting department.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below using specific examples. FIG. 1 is an explanatory diagram showing a specific example of the material processing management system of the present invention. The requesting department 10 shown in the figure is a department that arranges materials like a sales department and delivers the materials to another department to request processing. The processing section 20 is, for example, a section such as a pre-cut factory, which receives a material from a requesting section and adds processing thereto. These may belong to the same company or may be different companies. In this drawing, only the timber 1 that has been arranged is shown in the request section 10. This wood 1
Is delivered to the processing section 20 and processing is requested. For this purpose, the wood 1 is previously provided with an identification mark 3 that can be managed separately from all other wood.

The identification mark 3 may be, for example, a bar code or a number. In order to be able to distinguish all the materials, for example, a number combining the arrival date, material type, shipping date and other information may be generated each time. The identification mark 3 may be printed on the wood 1 or may be attached like a label. The request section 10 is provided with a first recording unit 5. The first recording unit 5 has a function of reading an identification mark attached to the wood 1 and recording the information in the storage device 21. Something like a bar code reader is suitable. Here, the first recording means 5 has the identification mark 3
The information that is read and stored in the storage device 21 is referred to as delivery information 22.

The processing section 20 is provided with a second recording means 6 for reading the identification mark 3 of the wood 1 received from the request section 10 and recording it in the storage device 21.
The information recorded by the second recording means 6 in the storage device 21 is called processing information 23. Normally, when the wood 1 is received by the processing department, the wood is first stored in a stock yard (not shown). Then, when performing a descending process, for example, a pre-cut process, it is taken out of the stock yard and set in the processing machine 11. Immediately before the processing, the second recording means 6 generates the processing information 23 and records it in the storage device 21. The processing machine 11 is a device for precutting the wood 1 based on predetermined design information. The processing information may include a part of the design information.

The original wood 1 is divided into several parts by the pre-cutting process, and a pre-cut material 8 is obtained. Here, the identification mark 9 is printed on each pre-cut material 8 by the marking means 12. The format of the identification mark 9 attached to the pre-cut material 8 is also free as in the case of the identification mark 3. The marking unit 12 receives the marking information 24 stored in the storage device 21 and prints the identification mark 9 using the contents. The marking information 24 is generated based on the processing information 23 as described later.

The precut material 8 is then returned to the requesting department 10. In the requesting section 10, when the precut material 8 is returned, the third recording means 7 reads the identification mark 9 attached to the precut material 8, and records the content in the storage device 21. The information recorded by the third recording means 6 in the storage device 21 is called return information 25. In this example, the storage device 21 is built in or externally attached to the management server 15 that can be accessed simultaneously from the requesting department 10 and the processing department 20. In this way, the management information can be referred to from any department at any time, and various managements are facilitated. However, the delivery information 22 and the return information 25 may be stored in the computer of the requesting department 10, and the processing information 23 and the marking information 24 may be stored in the computer of the processing department.

The first recording means 5, the second recording means 6, and the third recording means 7 are identification mark reading devices. The read data controls the storage device 21 wirelessly or through a network. Sent to the management server. Further, the marking information 24 is transmitted to the marking means 12 through the network. Further, the management server 15 is provided with management means 26. The management means 26 is composed of a computer program or the like for executing processing for confirming and managing the return of the material transferred from the requesting department 10 to the processing department 20. The management means 26
It has a function of generating the marking information 24 with reference to the delivery information 22 and the processing information 23, and generating a management table and the like described later with reference to the return information 25 and the delivery information 22 and the processing information 23.

FIG. 2 is an explanatory diagram of the contents of the information stored in the storage device 21. FIG. 2A is an explanatory diagram of the contents of the delivery information 22. As shown in this figure, the delivery information 22 includes, for example, a material type, contents of an identification mark, a request date, and other information. For the material type part, for example, material name, production date, production lot number, price information,
Shipping destination information can be included. The content of the identification mark is the content of the label or print mark attached to the wood 1 itself. The request date is, for example, a shipping date. When the request date is recorded, it is set as a management target until the material returns to the request section 10 from that date.

FIG. 2B is an explanatory diagram for explaining the contents of the processing information. This includes a material type, an identification mark, precut information, a processing date, and the like. The content of the material type may be the same as or part of the delivery information 22. The content of the identification mark is the same as the delivery information 22. The precut information includes information indicating how one piece of wood received from the requesting department is processed. Design information for precut processing may be linked to this precut information. The processing date is the date when the material was actually processed by the processing machine 11 shown in FIG.

FIG. 3C is an explanatory diagram of the contents of the marking information. The marking information 24 is generated with reference to the contents of the delivery information 22 and the processing information 23. Among them, the marking information is different from the contents of the delivery information 22 and the processing information 23. In this example, the pre-cut material 8 is provided with an identification mark 9 indicating that the pre-cut material 8 has been divided and processed by cutting from the same material, and the number of the divided number. For example, a precut material divided from wood having an identification mark of 1001 has an identification mark of 1001.
-1-5 and 1001-2-5.
1001 is an identification mark of the parent's wood, and the next -1 is
It indicates that the precut material was cut out first from the parent. The next -5 indicates that the image is divided into five parts.

FIG. 2D is an explanatory diagram for explaining the contents of the return information. Here, a return date of returning the precut material from the processing section to the requesting section in place of the processing date of the marking information is entered. Other information is the same as the marking information 24 described above.

FIG. 3 is an explanatory diagram showing the contents of the identification information of each precut material divided into five pieces from the parent wood 1. The precut material 1-1 has 1001-1
An identification mark of -5 is given. Pre-cut material 1-
2 is given an identification mark of 1001-2-5. In the same manner, 5 from pre-cut materials 1-1 to 1-5
An identification mark that can distinguish each of the divided pre-cut materials is provided. If each precut material is managed in this way, when the precut material is finally returned to the requesting section, it is determined whether the original wood 1 has been processed and whether all the pieces have returned to the requesting section. Can be.

It should be noted that, for example, a material that has caused a scratch or a processing loss in the processing section is not returned to the requesting section. In this case, it is reported as disposal.
The management unit 26 generates a management table as shown in FIG. 3B with reference to the delivery information 22 and the return information 25 stored in the storage device 21. By looking at this management table, it becomes clear how the actual base material was precut and finally processed. The management table is referred to by the manager of the requesting department, notified to the processing department as needed, and used for the smooth management of the material. The delivery information 22, the processing information 23, the marking information 24, and the return information 25 need not always be provided separately and independently as described above. The management unit 26 determines whether all the materials delivered from the requesting section 10 have been finally returned to the requesting section 10.
May be any content that can be compared and determined.

FIG. 4 is a specific operation sequence chart of the system shown in FIG. First, the requesting section 10 performs a request process for the prepared wood to the processing section (step S1). Following the request processing, the delivery information 22 is recorded as described above (step S2). After recording the delivery information 22 in the storage device 21, the wood is transferred to the processing section 20 (step S3). The processing section 20 performs processing for receiving the wood transferred from the request section 10 (step S4). The wood that has undergone the receiving process is stored in a stock yard (step S5). Next, the wood taken out of the stock yard at a predetermined timing is read with the identification mark, and the processing information 23 is recorded (step S6). Thereafter, the wood is pre-cut (step S7).

In the next step S8, each pre-cut material subjected to the pre-cut processing is marked. For this purpose, the marking information 24 is generated. In addition,
The marking information 24 may be generated before the pre-cut processing. Thereafter, marking is performed on each precut material (step S9). Then, the completed precut material is transferred to the request department 10 (step S1).
0). The requesting section 10 reads the identification mark 9 of the received precut material and records the return information 25 (step S11). Next, in step S12, the management means 26 generates a management table. Thereafter, the management table is used for evaluating the return state of the material. For example, it is possible to periodically refer to the management table and automatically inquire from the requesting department 10 to the processing department 20 for a material whose return status is unknown. Materials that are all determined to have returned to the requesting department are excluded from management.

FIG. 5 is an explanatory view showing a modification of the present invention.
(A) is a perspective view of wood of a modification, (b) is a perspective view of wood of another modification, and (c) is a perspective view of a plate material of still another modification. The present invention is not limited to the above embodiments. In the above embodiment, one identification mark is attached to one piece of wood, but in this example, a large number of identification marks 31, 32, 33,... Each of these identification marks has such a content that the part provided with the identification mark can be distinguished up to which part of the wood 30. Therefore, no matter how the wood 30 is cut, the cut material is in a state where the identification mark is given. That is, when the material is cut and divided, the identification mark may be given to the material at such a density that at least one identification mark is included in the divided material piece.

Therefore, it is not necessary to newly add an identification mark to the precut material. By checking all the identification marks of the precut material returned to the requesting section, it can be determined whether or not all the materials delivered to the processing section have been returned to the requesting section. Printing many identification marks on a material may impair the aesthetics of the material. In the example shown in FIG. 3B, the identification mark is provided by a fluorescent paint or the like. A number of identification marks 36 made of fluorescent paint are printed on the side surface of the wood 35. In this case, the identification mark 36 cannot be seen in a normal state. UV lamp 3 as shown
7, the identification mark 36 appears to be raised. That is, if the information is read using a special reader, the identification mark 36 can be recognized. In this example, the identification mark is a numeral, but may be a barcode. This makes it possible to manage the delivery and return of the material without being conscious of the identification mark.

In the above-described example, the description has been given by taking the example of the columnar wood. However, for example, the same is possible even with a board-shaped plate-shaped material. (C) is a plate 38
Are provided with an identification mark 39 at an arbitrary position.
In this case, no matter what size the plate 38 is cut, it is possible to include the identification mark in the cut plate. By the above method, when the sales department requests the processing department to process the material, the computer can automatically manage whether or not all the delivered materials have returned after the processing. In addition, it is possible to manage it very accurately.

Each functional block shown in FIG. 1 may be constituted by a separate program module, or may be constituted by an integrated program module. Further, all or a part of these functional blocks may be configured by hardware using a logic circuit.
Further, each program module may be operated by being incorporated into an existing application program, or may be operated as an independent program. The computer program for realizing the present invention as described above can be recorded on a computer-readable recording medium such as a CD-ROM, installed, and used. It can also be downloaded and used in the memory of a computer via a network.
