Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an apparatus for creating panel processing information necessary for processing a mounting board (panel) for attaching a device to a door of a control panel, a switchboard, etc. It is.

[Background technology]

In order to create panels for attaching equipment such as meters and protective relays to the doors of control panels, switchboards, etc., basic processing information must be created in a basic processing drawing, and the specifications and number of equipment to be installed, etc. Therefore, additional machining drawings are created for parts that require different machining each time.

Generally, additional processing drawings are created and used as door layout drawings for submission of approval. Basic machining information corresponding to the basic machining drawings is prepared in advance on NC tape, etc., but additional machining information is created through the following operations.

First, create a door layout diagram (Figure 1). In this case, the specifications of the equipment to be installed are investigated, and according to the prescribed standards, the outline drawing of the equipment, the dimensions of the installation position, the indication of the machining origin position on the parent drawing (basic processing drawing), the equipment code, the equipment name, the type, and the specifications. , drilling drawing numbers, etc. are written in association with the mounting position of the equipment. Next, the processing work (thin plate processing work) is performed using an NC machine (NCT:
In order to perform the process using an NC turret punching press (NC turret punching press), a person reads the dimensions from the machining origin to the mounting center point of the tool and the drilling pattern number written in the diagram, converts it into NC machining information, and uses the NC machining tape. Key input into the production device was required.

These tasks using conventional methods include:
Both require specialized training and a lot of work time. Furthermore, since the essence of the work is transcription or conversion of design information from the previous stage onto drawings, errors are likely to occur, which is an obstacle to improving work quality and work efficiency.

Also, since there are many orders where some machining in the basic machining drawing is canceled and another machining is added, use the NC tape for the basic machining drawing and the NC tape for the additional machining drawing separately in advance. If both tapes are unconditionally combined at the processing stage, unnecessary holes may be machined, causing damage.

Furthermore, the thickness of the door material is 1.6 according to customer specifications.
2.3, 3.2, etc. are often specified, so if the finished dimensions of a door, etc. are the same, the material development dimensions will change depending on the plate thickness. This means that the dimensions from the machining origin (lower left corner) to the attachment center point of the fixture displayed on the additional machining drawings change depending on the plate thickness of the parent drawing (basic machining drawing), so the additional machining drawings can be shared. This was a hindrance to standardization efforts.

[Purpose of the invention]

In view of these problems, the present invention accomplishes the following tasks that were previously necessary: () Investigating the installation specifications of the equipment at the drafting preparation stage () Investigating the equipment name, type, specifications, and drilling diagram at the drafting stage Filling in the equipment specification list section such as number etc. () Reading and transcription at the NC input information creation stage,
Input work () An object of the present invention is to provide a drawing device that automates the work of synthesizing partial processing cancellation information with respect to basic processing information, and facilitates the sharing and standardization of additional processing drawings.

[Summary of the invention]

The gist of the present invention is to create a drawing by utilizing an instrument outline symbol, a material center point symbol, and a processing cancellation symbol as symbols for creating a layout drawing, and to create a symbol master file related to the above-mentioned symbols, an instrument name related to the instrument outline symbol, A list figure data file containing figure data such as types, specifications, drilling drawing numbers, etc., a production command file containing data such as the relationship between additional processing drawing numbers and basic processing drawing numbers, material development dimensions, etc., and basic processing drawings.

(Explanation of creating a door layout diagram) Examples of creating a layout diagram are shown in FIGS. 3 to 6.

In FIG. 3, 201 is a frame diagram of a door of a control panel, switchboard, etc. In FIG. 4, 202A to 202C are instrument external symbols, 203 is a material center symbol, and 204 is a processing cancellation symbol.

In this example, the appliance code is “V” in the frame diagram of the door.
202A, "CS" 202B, and "10CR" 202C are placed, and a material center symbol is placed to show the association of the machining display origin with the parent diagram (basic machining diagram). An example of instructing to partially cancel processing is shown below.

FIG. 5 is an example of a completed door layout diagram completed according to the above example.

To explain how to create a door layout diagram according to the drawing procedure, first, draw a frame diagram of the door at a predetermined scale on the graphic display screen of the graphic display device 102 shown in FIG. If there is a drawing, it will be displayed. Next, call up the appliance outline symbol 202A shown in FIG. 3 from the layout drawing symbol library 102 shown in FIG. Key in the code “V” to install.

202B and 202C are placed in the same way, and the instrument codes are “CS” and “1OCR” at the designated positions, respectively.
Enter the key and install it.

In this embodiment, an example of the arrangement of three instruments is shown to simplify the explanation, but since a large number of instruments are generally attached, similar operations are repeated.

Next, in order to indicate the association of the processing display origin with the parent drawing, a material center symbol 203 is placed at a position corresponding to the center position of the developed material dimension of the parent drawing. Next, when it is desired to cancel a part of the processing in the parent diagram as necessary, the processing cancellation symbol 204 is placed at the corresponding position. The material center symbol and the processing cancellation symbol are expressed in a modified manner so that they are not conspicuously visible when outputted by the drawing output device 130, but are shown large for explanation purposes.

Finally, FIG. 5 is completed on the graphic display device 102 and stored in the layout drawing file 103.

(Description of graphic information extraction) The input interface unit 104 in FIG. 2 decodes the data in the layout drawing file 103 and arranges the data in a configuration that can be processed by a general computer.
It is stored in the layout drawing figure data file 105.

Layout figure data file 10 regarding Fig. 5
The graphic information stored in 5 is as follows.

Symbol: Coordinates (X _K1 , Y _K1 ), Symbol number 501 〃 : 〃 (X _K2 , Y _K2 ), 〃 502 〃 : 〃 (X _K3 , Y _K3 ), 〃 503 〃 : 〃 (X _C , Y _C ), 〃 600 〃 : 〃 (X _K4 , Y _K4 ), 〃 700 NOTE: 〃 (X _N1 , Y _N1 ), Character code V NOTE: Coordinates (X _N2 , Y _N2 ), Character code CS NOTE with arrow: Coordinates of the starting point of the arrow (X _N3 , Y _N3 ), character code 1OCR, information on line segments and dimension display for displaying the door frame, information on points generated during drawing, etc. are included, but from now on. Since it is not necessary for the data analysis, it is excluded from the extraction target.

Here symbol numbers 501, 502, 503, 600, 700
are the symbol shapes 202A, 202B, and 202B in Figure 3, respectively.
This is the number assigned in advance to 202C, 203, and 204.

(Description of the graphic data analysis processing unit 107) For the symbols among the data recognized above, the symbol number is used as a key item, and data in the symbol master file 104 in FIG. 2 is referred to to determine the symbol type code and drilling diagram. Find out the number.

For example, the symbol type code is defined as follows.

In Fig. 4, the symbol for the outer shape of instruments 202A, 202B, 202C, etc. is K, the material center symbol for 203 is C, and the undo point symbol for 204 is D.

Next, for those whose symbol type code is "K" (or "D"), the dimensions from the material center point to the fixture attachment point (or processing cancellation point) (X _Co ,
Find Y _Co ).

_{XCo = _ _ _ _ _ _}
(X _C , Y _C ) are the coordinate values of the attachment point of the material center symbol.

(Description of output information from graphic data analysis section) As a result of the above processing, the following additional processing information is stored in the additional processing information file 111 shown in FIG. 2.

(a) Additional processing drawing number (layout drawing number): Identification number (b) Additional classification (A: Symbol type code is “K”)
D: Symbol type code is "D") (C) Dimensions from the center point of the material to the attachment point of the equipment or the point of canceling processing (X _Co , Y _Co ) (D) Hole drilling drawing number ( (Only for those whose additional classification is "A") (Explanation of the processing information synthesis processing unit) First, the production command information is received from the production command file 109 shown in FIG.
Recognizes the additional machining drawing number, basic machining drawing number, and material developed dimensions that are paired, and calculates the dimensions (X _Co , Y _Co ) from the material center point to the attachment point of the equipment (or machining cancellation point) for the additional machining information. Convert it to the dimension (X _Oo , Y _Oo ) from the lower left corner of the material to the attachment point of the equipment (or processing cancellation point), and adjust the level to the reference point of the basic processing data.

X _Oo = X _Co + X _Z /2, Y _Oo = X _Co + Y _Z /2 Now (X _Z , Y _Z ) is the material development dimension of the data extracted from the production instruction file 109.

Next, for the additional processing information file 108 whose additional classification is “D”, we obtained the above (X _Oo ,
Y _Oo ) and the machining point coordinates in the basic machining information file 110 are found to match, and the data is deleted from both.

Next, for the data in the additional machining information file 108 whose additional classification is “A”, the coordinates of the machining point (X _Ao , Y _Ao ), processing type, and size data are extracted, and the coordinates are converted into the dimensions (X _OAo , Y _OAo ) from the lower left corner of the material to the mounting hole of the equipment.

_{X OAo = X Oo +} Add the data group that has not been canceled and output the following information to the output information file (a) Panel number (layout drawing number): Identification number (b) Material development dimension: Material cutting dimension (ha) ) Processing instruction information However, the processing instruction information includes: ・Position, type, and size of holes for manufacturing the panel itself ・Position, type, and size of corner notches for manufacturing the panel itself ・Bending of the panel itself Bending position, direction, bending dimensions, bending radius for processing, hole position for attaching equipment to the panel,
Consists of type and size.

These pieces of information (a) to (c) can generally be converted into a tape for NC processing according to a certain logic, and the production of the tape for NC processing can be automated using known techniques.

(Description of Graphic Data Processing Unit 122) Next, a specific example of creating a door layout diagram specification list, which is the second purpose, will be described.

The steps up to creating the layout drawing figure data file and extracting the figure information are as described above.

Next, regarding the symbol among the already recognized graphic information, using the symbol number as a key item,
With reference to the data in the symbol master file 104 of FIG. 2, the entry range position (ΔX, ΔY) of the list figure number and instrument code is extracted for the symbol type code "K".

Next, since the appliance code is attached within the figure of the appliance external symbol or with an arrow pointing out from the attachment point of the appliance symbol, the coordinates (X _Ko , Y _Ko ) of the appliance external symbol and the one-letter code are show sign
The association process with the NOTE coordinates (X _No , Y _No ) is as follows.

Find the character code of NOTE that satisfies the relationship |X _Ko −X _No |<ΔX and |Y _Ko −Y _No |<ΔY, and recognize it as the instrument code that corresponds to the instrument outer symbol. Next, the graphic data corresponding to the list graphic number already extracted corresponding to the appliance external symbol is extracted from the list graphic data file 121, and a combination of list graphic data corresponding to the appliance code is created.

(Fig. 6 301A, 301B, 301C) Next, in descending order of the Y coordinate of the instrument outline symbol,
The data is arranged in descending order of X coordinate, and the display position of the list graphic data paired with the instrument code is determined and displayed according to a predetermined rule. Next, predetermined data (302 in FIG. 6) corresponding to the title of the list is displayed at a predetermined position. Finally, the data determined in the above process is organized with a designated drawing number, and the equipment specification list figure data file 1 is created.
23.

The appliance specification list graphic data file 123 is stored in an appliance specification list diagram file 125 via the output interface section 124.

The figure is a graphic display device 10
2 can be called up as needed on the figure display screen (Fig. 6, 303), so the designer can overwrite the original drawing with the appliance specification list diagram created by batch processing using interactive processing, and then display it on the screen as necessary. Check the above and complete the drawing by adding, canceling, moving, changing, etc.

〔Effect of the invention〕

As explained above, according to the present invention, on the graphic display screen of the graphic processing device, devices that need to be attached to the door are placed, device codes are given, material center symbols are placed, or machining cancellation symbols are placed. For example, additional processing information on the panel can be automatically output, and equipment specification list diagram information can also be automatically created. Since the designer only needs to arrange predetermined symbols and characters under certain conditions, the specialized knowledge and experience that were conventionally required are no longer required.
Therefore, even an unskilled designer can easily create a door layout diagram of a control panel and a switchboard. Since design defects due to transcription errors, etc., which conventionally occur, will no longer occur, there will be great benefits in saving labor in design work and improving drawing quality.

Furthermore, by using a drawing method that considers the material center point as a reference point, a drawing method that utilizes a processing cancellation symbol, a graphic data analysis method, etc. according to the present invention, it is possible to overcome the problems associated with conventional drawing sharing and standardization. Furthermore, it becomes possible to centralize technical information from design, which can greatly contribute to improving productivity.
