[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the generation and utilization of product / assembly composition information (family tree) showing a list of drawings and parts / materials constituting a product or an intermediate assembly, and element information constituting the same. The present invention also relates to a family tree editing and design system for managing data.

[0002]

2. Description of the Related Art FIG. 12 is a diagram showing a current family tree generation method. The family tree is a child part (DE) constituting a product or an intermediate assembly (here, S) as shown in an example of 960 in FIG. 12, and further, a child part (FG) of the child part DE. H.J) are shown in a hierarchical structure (tree structure). In general, product production arrangements and cost estimation are performed based on the family tree data.

Conventionally, as shown in FIG. 12, a family tree has been automatically generated by computer processing by a tree expansion function of a database device 950. Prior to generation of the family tree, a drawing creation device 940 such as CAD,
Assembly drawings (9 in FIG. 12) are individually set for each of the child parts constituting the product.
10, 920, 930) and parts drawings. Assembly drawings and parts drawings are parts table information 911, 921, 931 for each drawing.
(Definition of the part information and the configuration information of the child parts and materials constituting the part information), and the family tree 960 is created by the database device 950 based on these.
Had been generated.

[0004] A parts table of an assembly drawing defines types and numbers of child parts having an assembly as a parent part. 911, 921, FIG.
931 is a parts table of an assembly drawing. The parts table 911 of the assembly drawing 910 indicates that the intermediate assembly S is composed of parts D and H. The parts table 921 of the assembly drawing 920 indicates that the intermediate assembly D is composed of parts F and G. The parts table 931 of the assembly drawing 930 indicates that the intermediate assembly E is composed of parts H and J.

[0005] In a parts table of a parts drawing, information of materials and processing information necessary for manufacturing the parts are defined. FIG. 13 shows an example of a parts table of a parts drawing. FIG. 13 is a component diagram of the component H, and its component table 941 defines the material, dimensions, weight, and the like of the component H in this component diagram. The database device 950 sets the final assembly drawing of a product or an intermediate assembly as the top-level parent component based on the information of the parts table of the drawing created by the drawing creation device 940, and defines the parts defined in each drawing. The parent-child information is sequentially expanded from the parent-child information to the lowest child parts / materials to generate a family tree.

As described above, the current family tree generation method is based on the parts list included in the drawings, and therefore, unless all the drawings necessary to construct the family tree are created and input in advance, the family tree is automatically generated. could not.

[0007]

Generally, in the initial stage of product development and design, there are rare cases where drawings of a new product or a new model change product are sufficiently prepared. Therefore, it is difficult to automatically generate a family tree of the product at this stage. Nevertheless, at this stage, it is effective to consider how to configure the product parts on the Family Tree.However, the designer repeatedly examines the paper while cutting and pasting existing product information. Is in a situation. In the early stage of development, it is important to accurately estimate product costs and other costs, which is an important task that determines the success or failure of product development.However, since there is no family tree, cost simulation by manual cost estimation and design changes is performed manually. Therefore, there is a dilemma that the accuracy is low in spite of the design load. In addition, there is a problem in that prior arrangement of parts and materials with a delivery date is also a manual operation, which hinders quickness of the arrangement.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, an embodiment of a family tree editing and designing system according to the present invention will be described with reference to FIGS. 1 to 4
1 is a schematic diagram illustrating an example of a configuration of a family tree editing and designing system according to the present invention. The family tree editing and designing system of the present invention includes, for example, a tree generating / editing device 100 for generating and editing a family tree, and various databases 300 for providing information to the family tree in both directions.
, Tree generating / editing apparatus 100 and database 300
And an interface device 200 for connecting the.

The database 300 is a basic database which is a drawing database generated and updated by a drawing creating device such as a CAD, and stores drawing title information, a parts table, and a drawing entity as "drawings". Further, “parts information” and “parts configuration information” are stored. The family tree itself is also stored in the database 300. These data are classified into verification data that has been verified in the database 300 and unverified data that the designer is working on. In addition, “cost information” and “production management information” are also targets of this system as a database group.

The tree generating / editing apparatus 100 registers a new object to be generated and edited, such as a new product, a model change product, and an intermediate assembly, as an "edit model".
It has a tree editing / searching / diverting unit for searching / diverting a family tree of an existing model or an intermediate assembly as a base of the “editing model”. At the time of this search / diversion, verification data and unverification data are also selected.

The tree generation / editing apparatus 100 holds the generated data as "edit data" in the apparatus as shown at 400. Since the generated data is held as "edit data", it is possible to graphically switch and directly display the information of the family tree in the tree display / editing section even when there is no individual drawing. Also, input / save of various data required for design study is displayed as a tree /
Performed by the editorial department.

Further, based on the "edited data", integration / file output processing (shown at 500) such as cost integration estimation, unit price estimation request to other departments, and parts arrangement (shown at 600) are performed. FIG. 2 shows a cost estimation summary table 510. FIG.
Shows a quote request form 610. In addition, design support utilizing the family tree is performed by inversely generating an individual drawing (parts list) from the family tree (shown at 700).
FIG. 4 shows a drawing (parts list) reversely generated from the family tree of the edit data 400. Normal generation, which has been performed in the past, generates a family tree from the bill of materials in the drawing.
It may be simply called generation.

Reference to the database in the process of retrieving, diverting, and editing the existing tree and reflection of the inversely generated drawing and estimate / arrangement instruction on the database are performed via the interface device 200. The interface device 200 links the data of the database 300 and the edit data of the tree generating / editing device 100. The interface device 200
Although shown as independent hardware in FIG. 1, the hardware need not be implemented by unique independent H / W (hardware). In this embodiment, a computer equipped with a program having an interface function of the tree generation / editing apparatus 100 and various databases 300 or an interface S / W (software) itself is shown. In that sense, the tree generating / editing device 10
0 may be considered to indicate a computer on which the program of the function is installed or the interface S / W itself.

Hereinafter, embodiments of the present invention will be described in detail. FIG. 5 shows a configuration diagram of the function of the present invention. In FIG. 5, reference numeral 110 denotes a tree definition / search / reuse unit for defining, searching, and diverting edit data 130; 120, a tree display edit unit for displaying and editing the edit data 130; A tree integration / output unit 150 for performing output is an estimate / arrangement instructing unit for instructing estimation and arrangement based on the edited data. In FIG. 5, tree generation /
In the editing apparatus 100, a designer directly generates and edits a family tree of products and intermediate assemblies by interactive operation. When considering a model change of a new product or an existing product, the designer activates the tree definition / search / reuse unit 110 of the tree generation / editing apparatus 100.

First, model information of a new product or an existing product whose model is to be changed is defined. The contents of the model information include a model code (“PA01499G05” shown at 402 in FIG. 1), a model name (“PLFY-J56M” shown at 401 in FIG. 1),
It consists of a model name (not shown). Next, the editing model (13 in FIG. 5) of the editing data is set using the defined model information as a key.
Register in 2). The edit model 132 of the edit data refers to an area in which the model information is stored.
It is registered as shown in

Next, if there is an existing product serving as a base for a new product / model change in the database 300, the family tree of the existing product is searched from the drawing database 310. FIG. 7 shows an example of a screen display when searching. FIG.
, 71 is a family tree search screen, 72 is a search model name input area, 73 is a search model code input area, 74 is a search button, 75 is a search result display area, 7
6 is a family tree display button, 77 is a family tree diversion button, and 78 is a cancel button.

First, the model information of the family tree to be searched is input as a key. In this screen, the model name and the model code are used as search keys, but “PLF *” is entered in the search model name input area 24 because it is desired to search for a model whose first letter is PLF. Here, search button 7
When 4 is pressed, a model having PLF as an initial is searched for and displayed in the search result display area 75. The operator
Select the desired model from the displayed search results and press F / T
When the (Family Tree) display button 76 is pressed, the Family Tree of the selected model is displayed.

In this way, the family tree of the new product / model change product to be created this time is edited with the selected family tree as the object to be edited. A set of drawing information constituting a family tree is extracted and copied to an editing database. The data copied to the editing database is referred to as editing data. By examining the addition or change of parts or materials based on the edited data, the designer can instruct cost evaluation and advance parts arrangement from the stage where there is no drawing of a new product or a model change product.

The link to the drawing database 310 is made via the interface device 200. A specific example of the function of the reference link from the drawing database 310 will be described below. From the tree generation / editing device 100, a tree definition
Key information required for generation / editing (model name / part number, etc.)
Is specified in the drawing database 300 in SQL.
(Structured Query Language)
e: sele of structured query language of database)
A ct statement is issued to obtain a family tree and component information / configuration information.

A specific example of a link function of reflecting a reversely generated drawing in a drawing database will be described below. An edited drawing (assembly drawing / parts drawing) unit is selected and extracted from the editing tree, and an SQL statement for inserting new data into the unverified data 314 of the drawing database is issued.

In general, the drawing database 310 often has a different form for each product, design department, and drawing type. That is, the system that generates and maintains the drawing database differs depending on the product and the design department.
This is because the application S / W is different. Therefore, there are a plurality of individual database schemas dependent on individual applications, and a group of them is called a drawing database. For example, specifically, the drawing name of the drawing drawn by the design department A is alphanumeric 20 digits, but the design department B is alphanumeric kana 32 digits, and the attribute of the drawing information is different between the electrical parts and the mechanical parts. The reason is that there is a separate database schema.

For this reason, in the interface device 200 of this embodiment, the interface device 2 is provided with a drawing link function that defines a data comparison table between the individual database and the edit database so that the edit database does not depend on those individual forms. To exchange data.

In the data comparison table, as described above, when the drawing database differs depending on, for example, the design department or the type of product / part, for example, the “drawing name” of the editing database is “A”.
Which field of which table in the design department database corresponds, and which data corresponds in the design department B, are defined. When data is copied, which data type / digit is to be integrated is defined in the data comparison table, and data shared as an editing database is extracted from a different database schema, or a reflection standard in the reverse direction is determined.

FIG. 8 shows an example of the structure of the drawing database. Although the form differs individually, the drawing database 310
Has basically the data contents shown in FIG. The drawing database 310 classifies and holds data in two broad categories. The verification data is “correct” verification data 312 that has been verified and output, and the latest unverified data 314 that the designer is working on at that time. In the unverified data 314, individual drawing information 380 is stored. The individual drawing information means that the drawing creation device 320 such as a CAD does not establish the drawing parent-child relationship because the drawings are created separately. In the verification data 312, the drawing verification / revision function 350
Is confirmed. For this reason, the family tree is generated by expanding the component information and the component configuration information generated from the drawing of the verification data 312, and expanding the parent-child components in order from the top-level drawing connected to the model information. The generated family tree is held in the verification data 312 as shown at 370.

FIG. 9 shows the relationship between verified data and unverified data. The new and old drawings are indicated by sub-number data of the drawing title information.
The sub-number data is numbered as follows, for example. In this embodiment, the sub-number of a new drawing (also called a new drawing) is “blank (blank)”, and each time the drawing is changed, the sub-number is sequentially assigned from A to Z. However, in this case, numbers can be assigned only in ascending order. As described above, there is a method of automatically proceeding with the subroutine, but a method of proceeding independently by a designer may be employed.

The data under revision is stored in a folder (also referred to as a working folder) 92 managed for each purpose of the revision work, and the sub-number and date are advanced. In the verification data 91, folder information is recorded in the recording drawing title information 94 in order to determine which drawing is working in which folder. When the folder content of the unverified data is verified, the sub-number, date, designer, etc. of the verified data are updated to the latest verified data, and the corresponding folder information is blank. At the same time, the drawing entity and parts list information are updated to the latest data, and the Family Tree is redeployed according to the latest information. After that, the unverified data is deleted. This series of processing is performed by a drawing verification / revision function 3 for controlling the drawing database.
Perform at 50.

The tree definition / search / diversion unit 110 shown in FIG. 5 selects tree diversion in the verification data and tree diversion reflecting unverified data when searching and diverting the existing family tree. The tree diversion of the verification data and the selection of the non-verification data are performed, for example, by displaying the status of verified and non-verification in the search result of the family tree search screen described above. When the designer selects the diversion source and presses the F / T diversion button 77 while checking the status of verified and unverified, the family tree is copied from the corresponding database.

The selection between the tree diversion in the verification data and the tree diversion reflecting the non-verification data can be made by selecting a new drawing or revised drawing which has been created or revised when a new product or model change is considered. This is performed to generate edit data by reflecting it in Diversion of verification data uses the data in the drawing database as it is. In the diversion reflecting the unverified data, all the drawing information in the family tree based on the verified data is searched, and if there is a working drawing as shown in FIG. 9, the drawing data and the children below the drawing are displayed. The drawing data is extracted and generated by replacing it with the relevant part of the family tree of the verification data. This processing is performed by the drawing link unit 210 of the interface device 200 shown in FIG.

The family tree generated in the editing database is freely edited by the tree display / editing unit 120 by the designer without depending on the drawing database, and the design is examined.
1 in FIG. 1 described above is a family tree editing (F /
An example of edit data displayed on the (T edit) screen 399 is shown. Here, the component configuration is graphically displayed as a family tree in a hierarchical structure (410). In the case of a family tree based on unverified data, it is also possible to highlight which part is currently being worked on by the drawing creation device 320 in FIG. In the tree display state, the content is directly graphically edited / updated by the editing operation menu 420 or the like. At this time, the existing drawing data in the drawing database is referred to via the interface device 200. Drawing information, component information, and component configuration information that is not in the drawing database (not yet created as a drawing) can be independently registered as edit data. These data are held independently in the editing database. On the F / T editing screen 399, various data required for design study can be displayed while switching screens, corresponding to the graphical tree display 410.

An example of screen switching will be described with reference to FIGS. In FIG. 10, the F / T editing screen 399 is configured to be divided into right and left. The left column 1001 is a tree area for always displaying a tree, and the right column 1002 is a view area for switching display contents corresponding to the tree. FIG. 10 is an example of cost display. FIG. 11 shows an example of order information (production management information). An example of the component information is as shown in the display 450 of FIG.

In FIG. 1, the display 430 of the cost information of the parts is performed.
Display 440 of production management information Switch display 450 of component information indicating various attribute information of components. The cost information and the production management information are supplied to the respective databases (the production management database 330 and the cost management database 34 in FIG. 5) via the interface device 200 when the editing data is initially diverted and generated from the drawing database.
Reference copy is made from 0) to the edited data. When the editing data is updated in the tree editing process, the latest cost and production management information is acquired via the interface device 200 by the instruction operation of the designer, and the corresponding editing data is also updated.

Next, a description will be given of how to take an interface according to a designer's instruction, the transfer of commands, operations, and information. If nothing is done on the cost and arrangement information held by the editing family tree in the editing database, the contents copied first are retained. During that time, the data in the various databases is updated daily, so that an operation for matching is performed at a certain timing. For example, after displaying the editing family tree, the designer instructs “refresh cost” and “refresh arrangement information” from the screen menu, and updates the components of the displayed editing family tree. It provides a function of acquiring the cost and arrangement information from various databases and displaying it again.

Further, the designer can input the design target cost and the estimated cost independently from the cost display screen 430. This is used for cost estimation 500 and unit price estimation request / part arrangement 600. Further, on the component information screen 450, data can be independently added or changed with respect to the component attribute information.

Next, other functions will be described. FIG. 1 shows three functions provided as a design study support function other than the editing of the family tree and the display of various data.
First, the cost estimation function 500 is described. In the early stages of development, cost considerations account for a large proportion of design considerations. It was difficult to perform this work with computer support in the early stages of design when the drawings were not aligned, but with the above-mentioned function of the present invention, the cost of new products and model change products was automatically integrated based on the edit tree, It is estimated as a cost summary table 510 shown in FIG. The cost tabulation table 510 in FIG. 2 is an example of a form for performing ABC analysis on the cost of a product. In general, when totaling costs, it is often the case that the costs are totaled and evaluated for each type of parts constituting the product, but in the cost totaling table 510, the types of the component parts are "sheet metal", "plumbing", "electrical goods", etc. Interim totals are used for those with a high cost ratio. The type of the component is calculated by judging data such as the component classification and the purchase classification in the component information and the order information. Furthermore, cost summary table 5
In the example of 10, the cost of purchasing a finished product by external work or outsourcing processing is “direct material cost (direct material cost)” and the “processing cost” of in-house processing is
Are divided into tally. The term “totaling” as used herein refers to multiplying the unit price of the components constituting the family tree by the number of components and summing up.

This cost integration function is a function obtained by applying the function of the tree integration / output unit 140 shown in FIG. In addition to the cost, the method is applied to the integration of weight and reliability data, and the tree information and the integration result are output to a file in a general-purpose spreadsheet data format, thereby providing more flexible data processing.

Also, in the tree display section 410 in FIG. 1, the parts for which the material department and the production engineering department are to estimate the purchase unit price and the processing time are marked, the marked part data is assembled, and a unit price estimation request is sent to the department. A function of issuing electronically (unit price estimation request / part arrangement 600) is provided. By performing this process, an estimate request form 610 composed of the marked parts is automatically generated, and the designer additionally inputs necessary information to generate request data. The cost data estimated by the request is the cost management database 3
40, and the designer acquires this cost data as edit data via the interface device 200,
Cost can be newly added.

In the same manner, the parts to be ordered in advance for the trial arrangement and production are marked on the tree display, and a parts arrangement request is generated electronically. By utilizing these functions, it is possible to quickly and accurately estimate a unit price, reflect the unit price, and arrange parts.

Also, in the present invention, drawing information (parts list) for updating drawing data by extracting drawing information from the editing tree, which is generated independently in the editing tree and has not been drawn by the drawing creation device, is updated. A function 700 is provided. In the reverse generation of the drawing information, a drawing (parts list information) 710 is generated from an editing tree, and data is transferred to the unverified data (314 in FIG. 8) of the drawing database via the interface device 200. In the edit tree, the working folder of the unverified data is specified in advance for the data to be reversely generated. At this time, if the drawing data already exists in the unverified data, a warning message is displayed to the designer. If the designer inputs no problem, the existing unverified data is overwritten. If the drawing data is not present in the unverified data, the data becomes new unverified data as viewed from the drawing database. Therefore, the consistency of the database is maintained by adding working data to the verified data.

As described above, in this embodiment, in generating a family tree indicating the parts and material composition of a product or an intermediate assembly, a tree generating / editing apparatus for directly generating and editing a family tree, and a family tree This system consists of a database that provides information in both directions and an interface device that connects the tree generation / editing device and the database group. The database contains drawing title information, parts table, parts information, parts configuration information, and drawing entities. And a drawing database in which family trees are stored, and cost information and production management information are also linked to the tree generating / editing device as a database via an interface device.
Define and register new objects, model change products, intermediate assemblies, and other objects that you want to create and edit as editing models, and use the tree editing / search / reuse unit to search and reuse existing family trees that serve as the base. In addition, the data generated by the tree generation / editing device is independently retained as editing data in the device. Even if there is no individual drawing, the family tree can be directly edited and various data necessary for design study can be input. The family tree editing and designing system, which has a tree display / editing unit capable of switching and displaying various data, has been described.

Further, based on the edited data, integration / file output processing such as cost estimation / estimation, unit price estimation /
The family tree editing and design system including the part arrangement request and the function of reversely generating individual drawings (parts list) from the family tree has been described.

In addition, the verification data that has been verified and the unverified data that is being worked on are classified and stored in the drawing database.
The family tree editing and design system has been described in which verified data and unverified data can be selected when a family tree is diverted or drawing data is referenced.

Also, a family tree editing and designing system characterized in that an unverified drawing (parts table) is reversely generated from a family tree of edited data and reflected in a drawing database has been described.

In the present invention, a system integrating the above functions is devised as a family tree editing and design system, and supports design study work at an early stage of design when drawings are not sufficiently prepared. As a result, the computer processing of the drawing information can be performed in two directions in real time, from the conventional one-way processing of inputting individual drawings to expanding the family tree. In addition, at that time, the system includes the drawings of “verified / unverified” and the management division of Family Tree, which are necessary for practical use, especially as unverified data when reversely generating drawings from Family Tree. Is effective. Furthermore, in order to make full use of the Family Tree upstream in the design, not only are the information groups and contacts required for many designs maintained, but also the Family Arrangement, such as direct parts arrangement from the Family Tree and cost aggregation / evaluation functions. We devised and provided a function to make the most of the tree. For this reason, a method of defining a contact point with various various databases and a method of coordinating with an individual application such as arrangement are specifically realized by the present invention. as a result,
There is an effect that independence and versatility of the tree generation / editing device can be secured, and implementation can be easily performed at any design office. In addition, by sharing, transmitting, and reusing the family tree study data electronically, including the reverse generation of drawing information from the family tree, the development period can be shortened and the cost can be reduced from the initial development stage.

[0050]

According to the present invention, a family tree can be easily generated electronically with an existing database as a background, without a completed drawing.

According to the present invention, the family tree can be generated / edited at the stage where the drawings are irregular, without affecting the completed drawings.

According to the present invention, a new family tree can be generated / edited by utilizing an existing family tree.

Further, according to the present invention, through the direct generation / editing of a family tree against the background of an existing database, from the initial stage of design with irregular drawings, the study of the component configuration is performed based on the data being edited. Estimate cost and product costs and arrange advanced parts quickly and accurately.

According to the present invention, drawing creation can be performed simply and quickly, and efficiency can be improved by inversely generating a drawing from a family tree.
