Description

The present invention relates to a drawing generating unit and drafting programs according to automate the creation working drawings for instructing the assembly order by the working process in the assembly operations of the control device or the like.

In the device generation method using 3D CAD (Computer Aided Design) in the design and manufacture of the control device, the shape of the control device is easier to visually recognize than the 2D design, and high quality drawings are created at the design stage. Is easy.
On the other hand, on the manufacturing side for assembling the control device, the assembly information of the components constituting the control device is used when the work instruction is given by a two-dimensional drawing such as paper, and the assembly order of the control device is classified by work process. There is a method of clearly indicating an assembly work instruction of the work process, and the control device can be completed by a high-quality manufacturing process as compared with the conventional method.

  In Patent Document 1, which is a publicly known document related to three-dimensional CAD, component model data for specifying the shape of a component and component attribute data of the component model data are input to generate three-dimensional model data, and a component configuration drawing , Outputting an assembly group component configuration table and an assembly component configuration table.

The "3D CAD drawing generation apparatus" of Patent Document 2 generates 3D model data for specifying the shape of each assembly, and is specific to each assembly for each part. It is described that a product number is given and a parts configuration table and a three-view drawing of each assembly are output as required by the operator.
JP-A-11-66115 (paragraphs 0031 to 0048, FIG. 2, etc.) JP-A-11-66137 (paragraphs 0017 to 0038, FIG. 1, etc.)

By the way, in order to improve the assembly productivity in the above-described assembly work instruction of the control apparatus, instead of the conventional assembly work instruction by the two-dimensional drawing, the control apparatus by application of the three-dimensional CAD is used. It is necessary to give instructions for assembly work.
Here, in the three-dimensional CAD model necessary for the actual product image in the work instruction drawing, a configuration model is sequentially created for each assembly process of the control device using the configuration function of the three-dimensional CAD.
However, unless the user switches the configuration, it is not possible to recognize what component is instructed in each process, and the device assembly process on the three-dimensional CAD cannot be imaged. Therefore, it is difficult to evaluate assembly workability, and there is a problem that productivity is not improved.

Also, when creating a configuration model for each process for the assembly model of the control device, the user manually selects a model to be instructed to perform suppression processing, and repeats an operation of newly creating it as a configuration for each process. Thus, the assembly model for each assembly process of the control device is completed. Therefore, the work man-hour is large.
Further, regarding the model suppression processing, when the three-dimensional CAD model is suppressed in the order of the assembly process, the model to be specified in the next process is in the suppression state, and therefore is not displayed on the assembly model graphic. It takes time and effort to search for the model of the component part you want to display with the file name, open the file for each component part, and check it.

Next, for parts information necessary for assembling the control device, a parts table in the order of assembly work is created, but the user can enter the component file name and attribute information of the three-dimensional CAD from the assembly model tree and graphics. Refer to the file for each component and manually enter it into the assembly parts table. Therefore, there is a possibility that an input error due to a human error may occur and the quality is not stable.
Also, when completing the work instruction drawing, the above-mentioned configuration model and assembly parts table are manually pasted to each work instruction drawing one by one for each process, resulting in a large work man-hour. .

Here, in the process of creating the work instruction drawing, when editing the attribute information of the component in the assembly parts table, a series of operations of opening the component file to be edited, editing the attribute information, saving and closing, The number of man-hours is large because one component is manually operated for each component to be edited.
Also, in the configuration model attached to the drawing by the operator, if the user wants to change the angle of the drawing view in the 3D CAD drawing for the convenience of the assembly work instruction, the user first determines the angle on the model first, Select the angle pasted in the drawing view on the model, change the angle with the keyboard or mouse, save the changed angle information, return to the drawing view, and select the saved angle. It takes time to go back and forth between the screen and the model screen.

When a configuration model is pasted as a drawing view, the user needs to adjust the scale several times in order to display a picture of the model as large as possible in a limited space, which takes time.
In addition, it is necessary to manually assign the row numbers of the assembly parts table as balloon numbers to the components of the configuration model on the drawing view, which is troublesome.

However, Patent Document 1 describes a technique for generating part model data, part attribute data, generating three-dimensional model data, and outputting a part configuration drawing, an assembly group part configuration table, an assembly part configuration table, and the like. However, a technique for solving the above-described problem is not described.
Similarly, Patent Document 2 gives three-dimensional model data for specifying the shape of each assembly, a unique product number, etc., limited to each assembly for each component. Only a technique for outputting a plan view is described, and a technique for solving the above-described problem is not described.

That is, Patent Documents 1 and 2 disclose a technique for obtaining an assembly drawing, details of each part constituting an assembly (assembly), etc. using a three-dimensional CAD. There is no description of a specific method that contributes to improving the production efficiency of the process, standardizing the assembly work instruction method for each process, and the like.
In view of the above circumstances, the present invention provides a 3D CAD model of an automated tool and a drawing creation apparatus and a drawing creation program for automatically creating a 3D CAD drawing that can improve the efficiency of creating a work instruction drawing and standardize an assembly work instruction method for each process. The purpose is to provide a program .

Hereinafter, the process of creating the work chart D for each assembly process of the control device by the automatic creation system S will be described in detail with reference to FIGS.
<< Details of Processing for Creating Work Drawing D for Each Assembly Process of Control Device by Automatic Creation System S >>
First, in S101 of FIG. 2, the user starts up a three-dimensional CAD in the client 103 (see FIG. 1). As a result, the three-dimensional CAD in which the control program is incorporated is executed, and the automatic creation system S enters an operating state.
Then, in the client 103 (see FIG. 1), the three-dimensional CAD assembly model A (see FIG. 3 (a)) in the assembly completion state of the control device created by the three-dimensional CAD is obtained from the three-dimensional database 101 (see FIG. 1). In the read state, each work shown in FIG. 2 is performed by executing an automatic creation function of a work chart for each assembly process incorporated in a menu bar (not shown) on a three-dimensional CAD displayed on the display 106 of the client 103. Steps (S102 in FIG. 2 to S106 in FIG. 2, S108 in FIG. 2, S109 in FIG. 2) are displayed as menus. Then, the user selects each predetermined menu, and the following processing is performed.

<Create folder>
In S102 of FIG. 2, when the user executes a folder creation menu (not shown) of the automatic creation system S (control program) displayed on the display 106 of the client 103 (see FIG. 1), the folder creation shown in FIG. A folder creation screen G1 of the operation screen to be performed is displayed.
The folder creation screen G1 (see FIG. 4) is a screen responsible for creating a folder necessary for creating the configuration model B (see FIG. 3B) used to create a work chart for each assembly process.

  The folder creation screen G1 shown in FIG. 4 displays a process name 201 in which a folder name 201a of each folder and a folder name check box 201b corresponding to the folder name 201a are displayed, and the name when a new folder is added. A text box 202 for inputting text, an add button 203 that is pressed when a folder having the name input in the text box 202 is additionally created, and creation of a folder using the process name 201, the text box 202, and the add button 203 are created. An OK button 204 that is pressed when confirming and a cancel button 205 that is pressed when canceling the folder creation screen G1 (see FIG. 4) are provided.

In the folder creation screen G1 (see FIG. 4), in addition to the folder name 201a of the process name 201 defined and automatically displayed, a desired process name is entered in the text box 202 and the add button 203 is pressed. The process name (folder name) can be added. As described above, the same name is used for one process name and the folder corresponding to this process.
A folder name check box 201b is provided for each process name, and is checked by default. The definition can be canceled by unchecking the folder name check box 201b with the mouse 105 (see FIG. 1) or the like, and it is possible to create only a folder for each necessary process name.

When the user presses the OK button 204 after confirming the assembly work process name using the folder name check box 201b, the text box 202, and the add button 203 on the folder creation screen G1 (see FIG. 4), the folder creation screen The folder determined in G1 (see FIG. 4) is automatically inserted into the three-dimensional CAD assembly model A (see FIG. 3A), which is the assembly completion state of the control device.
Then, the name of the folder determined on the folder creation screen G1 (see FIG. 4), the component part name or the component name of the three-dimensional CAD assembly model A (see FIG. 3A) in the assembly completion state of the control device, and Are compared, the component model having the component name or the component model stored in the component model having the component name is automatically stored in the folder, and the three-dimensional CAD is executed. Addition to the assembly model A (see FIG. 3A) is completed.

For example, when the number of component parts used in the process is one, the component part name and the folder name are the same, so the component model can be automatically stored in the folder. Alternatively, if the process name is the door of the component and the part model used in the process is put in the door model, the folder name “door” matches the model name “door”. A plurality of component models stored in the door model to be used can be automatically stored in the corresponding folder.
Thus, the addition of a folder as a function of the three-dimensional CAD is performed in the component tree in which the components of the three-dimensional CAD assembly model A (see FIG. 3A) in the assembly completion state of the control device are displayed on the hierarchy. A name is defined, and a folder having a component model for instructing work in each process can be automatically added collectively.

<Create configuration>
In S103 of FIG. 2, when the user executes a configuration creation menu (not shown) of the automatic creation system (control program) displayed on the display 106 of the client 103 (see FIG. 1), configuration creation is realized. A configuration creation screen G <b> 2 (see FIG. 5) that is an operation screen is displayed on the display 106.
The configuration creation screen G2 (see FIG. 5) is a screen having a function for realizing the addition of a configuration to the three-dimensional CAD assembly model A (see FIG. 3A), which is a completed assembly state of the control device.

  The configuration creation screen G2 shown in FIG. 5 includes a configuration name field 301 including a configuration name 301a in units of process names and a configuration name check box 301b that is checked by default corresponding to each configuration name 301a. , An OK button 302 that is pressed when the configuration set by the configuration name 301 is confirmed and created, and a cancel button 303 that is pressed when canceling the configuration creation.

Since the user can cancel the definition by unchecking the configuration name check box 301b for each process name with the mouse 105 (see FIG. 1) or the like, only the necessary configuration can be created. Yes.
When the user selects the process name using the configuration name 301a and the configuration name check box 301b and then presses the OK button 302, the control program of the automatic creation system S operates the three-dimensional CAD on the folder. The suppression state is switched in units of folders from the upper stage of the upper tree, and a configuration model is automatically created according to the assembly order of the control device.

In this way, the addition of the configuration which is a function of the 3D CAD is performed by adding a folder unit consistent number from the top of the tree of the 3D CAD assembly model A on the 3D CAD (see FIG. 3A) to the folder name. Configuration names can be automatically added as a configuration name.
Furthermore, angle information that can be displayed at a position that can be easily recognized by an assembly operator of the control device is automatically added to the three-dimensional model.

In other words, the angle information set in a predetermined angle unit (for example, a multiple of 5 degrees) based on the front and back surfaces defined in advance by the function of the three-dimensional CAD according to the assembly pattern in the control device is automatically generated when the configuration is automatically created. It is automatically added and the angle can be changed in the drawing view with the angle information.
In addition, in work drawings such as completed drawings, for example, in the case of a control device, a movable model such as a door needs to be displayed open so that a model of the entire process can be recognized. Then, a match condition for opening the door is automatically added, for example, an angle match of 90 degrees is added with reference to an existing angle match of 0 degrees.
For example, the angle match is 0 degree by default in the three-dimensional CAD, but if the angle match is 90 degrees in the control program, the angle match 90 degrees can be added when the configuration model is automatically created. .

<Device production information setting>
