Description

Detailed Description of the Invention [Field of the Invention] The present invention relates to a steel structure component comprising a design support computer for designing and producing a steel structure, a process computer that provides processing data to an NG control processing machine and an NC control processing machine. This invention relates to manufacturing equipment.

[Conventional technology]

Conventionally, in the production of steel structures, after designing the entire steel structure and partial detailed drawings, detailed drawings of the entire structure are designed again.

Based on this, we organize the necessary parts, create actual size data for the necessary parts, process the steel material to manufacture the necessary parts based on this actual size data, and then weld, bolt, etc. Assemble the steel structure into predetermined small units (products). The product is transported to a construction site and used there as part of the structure.

In order to facilitate this type of design, CAD systems and CAM systems have recently been developed, and attempts are being made to combine them with NC control to automate everything from design to production.

[Problems with conventional technology]

However, this is limited to bridges with patterned structures and connections, and NC processing requires cutting, drilling,
For each beveling process, batch processing is partially performed for each lot, and the degree of freedom in design, that is, the steel structure that can be applied, is extremely limited, and the degree of freedom in automatic processing, that is, the application There is a problem in that the processing that can be done is extremely limited.

Steel structures have a large number of components, and the types and sizes of structural rolled steel materials used as components vary widely, and an infinite number of detailed connection patterns can be considered, resulting in a wide variety of parameters for finalizing the design. . Therefore, no matter how much standardization is attempted, it is difficult to consistently combine CAD systems, CAM systems, and even NC control machining. In the end, although single-item production of parts is unavoidable, drastic improvements in production efficiency have been impossible because the system relies on batch production for each lot. In addition, after cutting the plates, six holes are made for each lot, which requires a great deal of effort to handle. On the other hand, in order to operate an NC processing machine from a design drawing via a CAM system, not only does it take an extremely large amount of effort to create and check data, but it is also inevitable that checks will be omitted and mistakes will occur, leading to production errors. It was also the reason for the invitation.

Since NC control machining requires an extremely large amount of labor to create machining data from design drawings, it is limited to a limited number of machining processes for relatively large quantities of parts. Furthermore-
There are attempts to move forward and connect the so-called CAM system, which takes actual size data from an automatic work drawing creation system, to NC-controlled machining, but since the designs themselves vary widely, structures and connections are limited to those that can be patterned. After all, it takes a lot of effort to create input data to the system. On the other hand, there is a movement toward designing using interactive CAD systems, but since it is all about drawing the design drawings, C
It is difficult to use AD data directly as input data for a CAM system for manufacturing, and at the same time, since the drawings are patterned and standardized, the accumulated data is difficult to search, and at the same time, some design conditions may be required. Even if something changes, it is not easy to modify it, making reuse difficult.

In this way, various designs become the biggest bottleneck in achieving consistent automation of high-mix, low-volume production by linking design CAD data and manufacturing CAM data and combining them with NC-controlled processing equipment. Not only does checking require an extremely large amount of effort, but also checking omissions and checking mistakes are unavoidable, leading to parts being manufactured incorrectly.

The present invention allows for various designs of steel structures while maximizing the effects of design standardization, and provides automatic design with high productivity, flexibility, and reliability.

The purpose is to produce.

[Means for solving problems]

The steel structure parts manufacturing apparatus of the present invention organizes and generalizes the detailed design data of each member end around the node of a steel structure with respect to the part of the member and the type of steel section used, and produces standardized design data. The stored design standard value file, the special joint design standard value file that stores the design data in which the detailed design data of special joints that are not in the standard value file are standardized for each special joint pattern, and the Structure definition image creation means for defining specifications and their arrangement; fitting processing means for reading design data from the standard value file, editing design data for each node of the structure, and determining fitting of members at each node; Interference processing means for eliminating interference between component members at each node, detail processing means for generating additional part information and processing information necessary for joining members at each node, a simulation processing means for creating part data; a drawing creation means for creating image information showing the finished shape of the arrangement of the constituent members and additional parts; and
Manufacture of steel structure parts, including a processing data editing means for editing processing information of the constituent members and additional parts into actual size data corresponding to each part, and a production planning means for allocating processing data of the constituent members and additional parts to materials. an information creation device; and a marking means for attaching machining instructions such as a designated part shape and machining position to the material based on the machining data created by the manufacturing information creation device for steel structure articles; A steel component processing device comprising: a drilling means for making a hole at a position, a cutting means for cutting a specified position of a material, and a beveling means for forming a specified bevel at a specified end; Be prepared.

[Effect]

Most of the input data for the CAM system is created automatically since the design stage (CAD system) replaces the design drawing procedure with the actual processing procedure, processes the actual data, and performs a complete automatic design from the manufacturing point of view. be done. Therefore,
This greatly reduces the effort required to enter data into the CAM system and the unnecessary repetition of processing due to omissions or mistakes in the design drawings.
Moreover, it is possible to prevent production errors. On the other hand, the machining procedure is written in elemental and generalized manner for each member end around the node, or if it cannot be generalized, the machining procedure and standard dimensions of the shiguch for each node are made into a cassette as a special shiguch, and Dimensions of end joints of each member are standardized for the parts where the section steel is used, and these are combined arbitrarily and processed for each node, allowing for a variety of designs. In addition, past results are stored not as drawing data, but as standard value files of design data or cassette programs and standard value files that store processing procedures and data for special shiiguchi, making it easy to reuse past know-how. Therefore, it is easy to customize by simply replacing the standard values, and it is possible to efficiently respond to a variety of designs. Through this integrated CAD/CAM system, NC lines are created according to CAD/CAM data, material type, and processing characteristics.
Controlled machining and batch-based NC-controlled machining can be flexibly combined, making it possible to automate the high-mix, low-volume production of steel frame parts that can accommodate a variety of diversified structures while maximizing the effects of standardization. It also makes production management easier.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

The design standard value file A (a) in FIG. 2b is a data file that is standardized by associating the type of steel section with the detailed information on the end design of the member for each part of the building type. Special Shiguchi cassette program module group (b) describes the design procedure for each special Shiguchi in a Special Shiguchi design standard value file (c)
This is a group of program modules (program library) written using . The special shikiguchi design standard value file (c) is the cassette progera l of the module group (b),
The detailed dimensions of each special shikiguchi are written in to create detailed data for design. The design standard value file B (d) is a file in which detailed dimensions of joints/joints necessary for design processing and local parts common to each part are written. The welding standard value file (e) is a file in which plate combination patterns, detailed shape data of welding grooves marked for each size, and shrinkage allowance/processing allowance data are written.

Files (A) to (E) in Figure 2b are data files for each property that result from the processing, and the basic design condition file (A) is given by the designer or operator and is shown in Figure 3. Consists of 3 types.

The detailed design data file (a) is detailed information on the member end design for each node that is automatically created and edited by the detailed design data editing process from the basic design conditions (a) and the design standard value A (a). There are two types shown in Table 4.

The special joint design detailed data file (1) in Table 4 is a special design that has been designed and processed from the detailed design data (a) and the special joint design standard value file C using the special joint cassette program module group. Detailed dimensions of each part of the mouth.

The design database (1) contains the results of design processing using the detailed design data file (a), the special joint design detailed data file (2), and the design standard value B (d). Data that shows detailed processing conditions for parts and products, such as overall arrangement of parts, assembly conditions of parts, and processing conditions (

The machining database (e) contains data showing the details of the three-dimensional distribution and shape of parts such as sections and plates, which are the results of simulated machining using the design database (1). It consists of actual layout and shape data of steel sections/plates with part connection data such as assembly/product assembly/subassembly.

The production database (power) is the result of actual size processing and production planning processing using the processing database (e),
This is a data group for performing processing and assembly by NC control as shown in Table 5.

Each processing block shown in FIG. 2c is processed using the design system 1° according to instructions from the designer or operator.
This is automatically done in batch processing. Before and after each of these blocks, the designer or operator creates, changes, and adds input data using the design system 10.

Next, a schematic flow of design A and work design B by the host computer 11 of the design system 10 and (one of) the design devices 12 to 16 connected thereto is shown. The details of the automatic processing of each block will be explained along FIG. 2c.

First, in design A in FIG. 2a, detailed design data editing AI, design processing A2, and processing design A3 (A3-1+A3-2) are executed for a typical frame of a structure.

In design B of Figure 2a, design A for the entire frame of the structure.
(A1+A2+A3) is executed again, and production design A4 (A4-1+A4-2) is executed.

FIG. 3a shows the relationship between data files and the flow of automatic processing performed in the detailed design data editing A1 shown in FIG. 2c.

This detailed design data editing A1 uses the basic design conditions (1, 2) and design standard values A(a) input by the designer, and the processing/joining member standard value file (6) to process the design. The complete detailed data (1-7, 7) required for A2 is automatically created, and the data is developed and edited (3, 4, 5, 7) into a form that facilitates subsequent processing of each node.

Here, first, 1-1 to 1-6 of structure definition data (1)
Up to this point are the basic parameters of the special shikiguchi exemplified for the skeleton and the second garment illustrated in Fig. 4a, and the members table (2
) is the member data illustrated in Table 1.

These are basic design conditions given by a designer or operator through an image processing terminal or the like. In addition, the special Shiguchi basic parameters illustrated in the second garment are based on this structure definition data (1)
As shown in 1 and 2 above, the attributes of the nodes are defined through the image processing terminal.

In member attribute generation (101), gutter structure definition data (1)
Select the steel section type corresponding to the member name/part name (1-4) from the member table (2), read the design standard value file A (a) using the selected steel section type as a key, and calculate the member attributes. Automatically set and write in (1-7).

Details of this component attribute are shown in Table 4.

The above relationship is shown in Figure 5a.

In this way, when creating design data for a structure, the design standard value file A (a) automatically generates all the member attributes necessary for design processing simply by providing the member name/part name and the type of steel section. This is a file for setting. This file allows the designer to design according to design standard values set in advance. This file is set to be editable for each designer and for building type 111th.

Figure 5b shows the specific structure of this file.

Note that the design member code and the constituent material pattern are standardized so that there is a one-to-one correspondence with the member name/part name.

In the three-dimensional bridge detailed data generation (102), the structure definition data (1) that has been processed in the member attribute generation (101),
The three-dimensional structure design data consisting of the member table (2) is converted into a form (3, 4) that makes it easy to repeat processing for each node thereafter.
, 5).

File (3) is the coordinates that should be included as attributes of the node.

These are the special joint name and its basic parameters, and the file (5) is data such as the priority order that should be held as an attribute of the member. File (4) is node connection data of members and frame surfaces for arbitrarily extracting separated node attributes and member attributes according to processing needs.

When file 3.4.5 is completed, calculate each point perpendicular to the center of gravity of each member that gathers there for each processing surface by taking the node given as input in skeleton gravity line conversion (103), and input it. Replace the skeleton given by the member center line.

In the target black reference 2 member setting (104), for each member that gathers at the contact point for each processing surface of each contact point, search for a member that is closest to the contact point and one member in the counterclockwise direction and has a higher priority than itself. Then, set the basis for determining the crossing aiming point of each two members that will wrestle (l! Set the two members that will strike, set the member aiming point pattern, and write it in file (7).

Plate subsidence pattern setting (105) focuses on two members, each member and the member attached to it, for each processed surface of each node, and connects gusset plate generation information and gussets from the 9 rotation angles of each type of steel section and the joint code. The fitting pattern of the joint plate, such as the plate mounting surface number, is processed/read from the standard value file for connecting parts (6) and written to the file (7).

This process/connection member standard value file (6) focuses on the two members that connect the joint plates, such as the plate attachment level, plate expansion angle, stiffener generation pattern, etc. This file is standardized for each rotation angle and connection code, and is edited for each designer and building type.

An example of the structure of this file (6) is shown in FIG. 5c, and an example of the mounting level of the plate according to the connection code/type of steel section/rotation angle is shown in FIG. 5d. FIG. 5e shows an example of a stiffener generation pattern.

Through the above processing, the detailed design data (a) shown in FIG. 2b is completed, and the input data necessary for the design process A2 is prepared.

Nao, place! (103/104/105) are automatically repeated for each processing surface (member processing surface) for each node of the structure.

For example, when the three-dimensional skeleton of the structure shown in the upper part of FIG. 9 is decomposed into component processing surfaces, it is as shown in the middle part.

FIG. 7a shows the flow of automatic processing performed in the design process A2 shown in FIG. 2c.

This design processing A2 uses the detailed design data (a) (Figure 2b) created in the detailed design data editing A1, the special shiiguchi design standard value (c), and the design standard value B (d). Then, a complete design necessary for processing design A3 is automatically performed and the results are written into the design database (1).

First, the settling process (22) automatically fine-tunes the member position for a given member skeleton so that each member end fits at each node mouth, referring to the design standard value B(d) if necessary. It is for making adjustments.

In the aiming point setting (222), as shown in FIG. 3a (104)
The target point setting base 'P! The intersection of the centroid lines of the two members is set as the target point of the processing member. However, if the reference member is on the left,
If only one side of the right side does not exist, and 2
Even if there are members, if their centers of gravity are on the same line and there are no intersections, the point obtained in (103) shown in Figure 3a is placed perpendicular to the base axis of the reference member. point,
In other words, the target point is a point placed vertically on the axis of the reference member.

Here, the reference axis refers to the center of gravity line/outer outline line/inner outline line, etc.

Converge the aim point at each node by repeating these aim point setting procedures twice, or three or more times if necessary.6 Even if the aim point has been converged once, if it is specified by input 1 Points moved by (ΔX, Δy) and (Δy, Δz)+(ΔZ, ΔX) for each surface based on the coordinate axes of the skeleton surface are set as new target points.

If there is a special tie, the target point is changed in a routine (223) according to target point change data determined by a special subsidence processing program to be described later.

Next, in the interference process (23), each member is placed while the skeleton that has completed the settling process (22) is fixed, and the interference part of each member end is cut at each node to find the material end cut point. can be.

In routine (231), the priorities of each member at the node are compared with each other, and the material end cut point on the center of gravity of each member is set in the order of priority for member end cutting.

Detail processing (24) reads the end joint data of each member at each node from the design standard value file B (d), and determines the arrangement and shape of the seed plates of various joint plates (diaphragms, gussets, stiffeners, rib plates, etc.). Determine. Additionally, the position of the cut point at the end of the member is changed as necessary.

In the routine (242), Shiguchi design standard value file B
Read (d) and find the apex candidate point of the gusset plate on the processing member side.

In the routine (243), the Shiguchi design standard value file B
Read (d) and find the vertex candidate points of the gusset plate on the other side that the gusset plate on the processing member side will engage with.

In the routine (244), the apex candidate points of the gusset plate determined in steps 242/243 are connected to determine the shape of the gusset plate seed plate, and the shape is shaped as necessary. At the same time, conditions for combining a plurality of gusset plates on the same level into one are set.

If there is a special tie, the cut points and cut lines are changed in a routine (245) according to the edge cut point and cut line change data determined by a special detail processing program to be described later.

In the routine (246), the material end cut point determined in 231 is corrected if the material end cut point needs to be changed. Also, if an irregular cut is required, add the cut line and its case point.

In the joint processing (25), the design standard value file B (d) is read, the position of the members at the joint position is checked, and the position of each joint is determined.

The above process is automatically repeated by sequentially extracting the machined surfaces of each node of the structure, as shown in FIG. 7b. Here, the processed surface refers to the facing surface of the member or plate that is perpendicular to the processing direction of the member or plate. However, only the joint processing is automatically and repeatedly performed for each member.

Note that FIGS. 8a and 8b illustrate an overview of the series of design processes for one machined surface of one node. In addition, the contents of the design standard value file B (d: Fig. 2b) used for the above processing are (d-1) structural procedure file, (d-2) joint standard value file, (d-3
) Gusset joint standard value file and (d-4) Bolt arrangement/gauge dimension standard value file.

The n-building procedure file (d-1) stores the data shown in the right column in FIG. 12a using the data shown in the left column as a key, and reads out the data in the right column by accessing the data shown in the left column. The structure outline file (d-1) stores detailed local dimensions (standard values) common to various details. 0 of them. An example of common joint dimensions is “overlap allowance for fillet welding AJ”.

"Turning welding allowance B" and "clearance C with joining material" are shown in Fig. 12b, and an example of the positional relationship, clearance, etc. between the gusset and the section steel corresponding to the rotation angle is shown in Fig. 12c.
An example of the determined dimensions on the section steel side is shown in Fig. 12d.

(d-2) The joint standard value file provides detailed splice dimensions of joints made of the same material based on the joint code and type of steel. FIG. 13a shows the input for specifying data (left column) and the data to be read (right column), and FIG. 13b shows the columns on the file accessed by the input. By specifying a certain joint position and joint code as shown in the left column of FIG. 13c, information on the joint specified by input is written in the specified position as shown in the right column.

(d-3) The gusset joint standard value file provides detailed dimensions of the gusset joint by joint code and type of steel. Fig. 14a shows the input for specifying data (left column) and the data to be read (right column), and Fig. 14b shows the columns on the file accessed by the input. By specifying a certain gusset position, joint code, and type of steel as shown in the left column of Fig. 14c, the detailed gusset joint dimensions specified by input are written in the specified position as shown in the right column. It will be done.

(d-4) Bolt arrangement/gauge dimension file is for joint/
It gives detailed bolt arrangement dimensions for joint codes and type steel types, and when the input shown in the left column of FIG. 15a is given, the data shown in the right column is read out with the access shown in the center column.

As a result, the information shown in FIG. 15b is written to the designated position.

Next, of the design process A2, special joint design process (A2-1)
will be explained based on FIG. 2b.

Special joint design treatment (A2-1) is for column base/panel zone/
If there is a special joint such as a truss end, read the special joint name and its basic parameters specified in the input of the basic design conditions (A) from the detailed design data file (B), and specify the special joint by the designer in advance. Automatically generates detailed design data (pieces) related to the special joint required for the design process of the entire structure from the special joint cassette program module group (f) set for each pattern and the special joint design standard value (c) It is created in

The special joint design process (A2-1) includes a special subside process (213) and a special detail process (213) as shown in FIG. 6a.
214).

The routine (213) determines special aiming points for members at special nodes, such as column bases/panel zones/shed truss ends, and feeds the data into the overall structure settling process (Figure 7a, 22). It is something to be handed over.

The routine (214) also performs the joint design process at special nodes such as column bases/panel zones/shed truss ends, determines the shape, placement, and bolt arrangement of various plates, and If necessary, it generates member end cut point/cut line data or plate processing conditions such as combining multiple plates into one, and passes the data to detail processing of the entire structure (FIG. 7a, 24).

As shown in FIG. 6b, the special shiguchi design standard value file (C) is structured so that complete detailed data of the shiguchi can be read out using the type of the special shiguchi and its basic parameters as keys.

Taking the panel zone/haunch as an example of the special rotary type, a specific example of the readout relationship is shown in FIG. 6c.

The above processing is automatically repeated for each machined surface of each special joint node of the structure.

Next, Fig. 16b shows the contents of "simulated machining process JA3-1" of machining design A3 shown in Fig. 2c. This simulates a process similar to when actually machining parts on a computer, This subroutine automatically generates data for machining (parts machining).This subroutine is specified by input, and a certain section of a certain structure created in the above-mentioned design process is specified by the designer or operator. Then, the design data group for this division in the design data database (FIG. 2b) is specified, and based on this, the process shown in FIG. 16b is automatically and repeatedly executed for each part.

That is, the design system 10 first defines (generates) and arranges (assembles) pieces (shaped steel) based on processing condition data in the design database, and then creates pieces (various steel plates: diaphragms/stiffeners/ribs/gussets, etc.). Define (generate) and arrange (assemble) (33
1). Next, a plurality of steel plates (gussets/diaphragms, etc.) at the same level are synthesized based on the design conditions, and a build-up section steel is defined using the pieces (steel plates) determined in the above subroutine 331. Then, the rolled steel section is disassembled into built-up type t [(I plate) (33
2). Next, the parts are cut together based on the processing condition data for each part in the design database (mainly in the panel zone), the parts are lengthened/shortened, and then cut (mainly in the material ends and joints).
. Alternatively, pieces may be cut together, members may be cut into pieces, or pieces may be cut into members. Or cut a member or piece in a shape (line, closed shape). Or H
A portion of the flange of the section steel (member or piece) is cut with a piece (gusset plate) (333), and then a hole is drilled in the member or piece (334). Next, the member or piece is bent, and the member or piece is further subjected to drawing processing (cutting and bending) (335). The above processes (331 to 335) are automatically performed for all parts. This generates all machining information for all required parts in the machining data database.

Next, production management basic data is created based on the data generated in this way. That is, basic data regarding production control such as the number of parts, weight of each part, surface area, cutting length, number of holes, etc. is created (336). Next, the connections between the parts are recognized, and it is determined whether they are in contact with other parts.
Or find the number of bolts for each diameter and neck length (337)
. Next, each part is automatically classified and numbered according to the same part processing conditions such as design mark (part name), size, material, processing shape, position, etc., and a part mark is attached (338). Next, the connection data between parts is determined, and products with the same assembly conditions for each part are automatically classified and a product mark is attached (339). The processing data and production management basic data generated above are then stored in the processing data database.

By the above "simulation processing JA3-1, the above-mentioned A1
Processing information is generated in the "processing data database" based on the "design data database" generated in the "detailed design data editing" and A2r design processing.

Next, the design drawing/work drawing creation/form editing JA3-2 of the machining design A3 shown in FIG. 2c is shown in FIG. 16c and will be explained with reference to this. First, an overview will be given.

During overall assembly, subroutines 401-403-4
A drawing database is generated in step 04, and during product assembly, the drawing database is generated in subroutines 402-403-404-405-406. Then, based on the drawing database, plot data is created 407 and a product inspection list is created 408.

Next, to explain in detail, first, figure/cross section data of the required part is extracted from the machining data database, coordinate transformation,
Scale (401/402).

Next, fill in dimension B/dimensions/product/parts mark, material, etc. (write data to drawing frame) (4)
03). The above processing is performed for all products to create all partial diagram data for each product. Next, each partial drawing is placed on each required drawing, taking into account the scale, and the name and dimensions of the overall layout basic line are entered (404). As a result, product data was organized in the form of drawings. Furthermore, in the case of product assembly, the number of pieces (number of pieces) of each product is calculated, and the product mark/number of pieces is written on the required drawing (405).

Create a key plan showing the z-product equipment on the required drawings (
406). Next, if there are any inconveniences in the drawing notation, such as overlapping characters or dimensions, in the automatically generated drawing (drawing database) as described above, the operator corrects it through dialogue (409).
. When generating a product inspection list, edit a list (408) in which dimensions and appearance drawings to be checked during assembly are entered for each product, and print it out (41).
4). When obtaining design drawings/work drawings, the drawing data in the drawing database is converted into a plotter data format (407), and the drawings are printed out by the plotter (410-413). In the case of the overall assembly design drawing (410), the arrangement of all products is developed for each frame surface, and depending on the scale, a general drawing or detailed drawing is obtained. In addition, the case of the work drawing (411) is essentially the same as the case of the design drawing (410), but generally only the general drawing is obtained.

In the case of a design drawing for a product assembly unit (412), a part of the factory assembly disassembled into actual joints is outputted, with details of each part developed for each product. In the case of a work drawing for a product assembly unit (413), all of these are output.

An example of a general drawing of a design/work drawing is shown in the lower part of FIG. 9, and an example of a work drawing broken down into product units is shown in FIGS. 10a and 10b.

Next, among the production design A4 shown in Fig. 2c, "actual size machining/form editing JA4-1" is shown in Fig. 16d and will be explained with reference to this. First, the above-mentioned processing data database (
2b and 16b) and refers to extract part processing shape data (461). Next, if there is a bending process, it is expanded to find the shape of the part before bending (462). Next, the combined marking data is edited (463). Next, referring to the weld line position, length data, shape, and welding standard value, the weld joint shape is determined, the weld length is calculated, and if necessary, backing metal is generated and registered (464
). Next, the welding line intersection is recognized, scalloping is performed with reference to the welding standard value, and the final part shape is determined by taking into account the welding shrinkage margin (465). All of the above processing is automatically executed with Z+L.

Next, the number of identical part marks (with the same processing conditions) is calculated, and the part marks/number of parts/materials are entered on the part drawing (466). Then, the above actual part size data is edited for each drawing output unit and stored in a drawing database. When an instruction is given to output a full-size processed drawing, the corresponding drawing data in the drawing database is converted into the data format of the plotter (469), and the drawing is printed out by the plotter. An example of the actual size processing drawing is shown in FIG. 11. Various production control data obtained through actual size processing are edited into a form and printed out (468).

Next, of the production plan A4 shown in FIG. 2c, "Production plan JA4-2" is shown in FIG. 16e and will be explained with reference to this. nesting), determine the standard length, standard width, and quantity of the material, and assign a material lot ID (identification code) as well as a material ID/part ID.In the case of steel plates, irregularly cut plates The removal is done interactively using CAD (471).Next, the NC machining data is edited for each lot (472).Next, the time required for each machining process is calculated for each lot. (473).

Next, we determine the machining loft for 2 to 3 days based on the machining urgency that takes into account the construction order and the machining man-hours in the post-process, and we also determine the machining capacity of each process by adding up the machining time required for each machining process for one day. Set the machining order of each loft so that the load of each machining process is balanced as much as possible (4).
74). Then, based on this set lot processing order, create a "Material stocking schedule data file" and a "Mountain/Forest (processing) order data file (including processing specification deletion data)" for several days including the day of processing, and The processed data is transferred to the Kanji system 30 (475).

FIG. 17a shows an outline of the structure of the section steel part processing line apparatus 34A (FIG. 1) in the part processing C shown in FIG. 2a, and FIG. 17b shows an outline of the arrangement of the cut plate part processing line apparatus 35A. These processing line devices are comprised of automatic warehouses (flat racks, three-dimensional racks, vertical racks, etc.), various processing machines such as NG sub-control, and transport lines. Other processing lines of the Kanji system 30 also have a similar configuration.

Figure 18 shows the elaine equipment for each shaped steel part [34A], the process computer 35B and various equipment for the processing line 34A (
computer, controller)
Note that in other processing line devices, a system similar to the computer connection system shown in FIG. 18 is configured.

Referring to FIG. 18, the process computer 35B operates as a central processing unit of the section steel parts processing line, and performs data input/output 1 editing, status monitoring, calculation, etc. Analyze the machining data, determine the tool path, and convert the machining data to NC data.

In the case of steel plates, the NC data may be stored in a portable (portable) controller.

In the line control bag, NC'U is a 9 communication control device that controls the reception of processing schedules and processing specification data sent from the design computer (10), and controls the transmission of processing performance data collected at @babatami. The CCU controls data transmission and reception between the process computer 35B and the actual product terminal 35C and the computers and controllers of each processing equipment, as well as between the actual product terminal 35C and the computers and controllers of each processing equipment. The terminal interface control device TIF monitors the status of control terminals (various processing equipment) and transfers processing specification data.

The communication interface CIF is a protocol for performing each communication. The spot terminal 35C serves as an on-site terminal.
M in the processing line! There are two terminals installed, and they display the buffer status of each control terminal (various processing equipment) and communicate with operators on site.

The process input/output device 1PIO corresponds to the control panel or operation panel of various processing equipment, and is composed of a PC-level computer, and is responsible for emergency stop, -temporal stop, and operation of each control terminal, conveyor controller, etc. Or, it sends out instructions to change the control, performs manual control (based on operator input), etc.

FIG. 19a shows a process computer (34B) in each processing line device in the processing system 30.

35B) shows the control operation up to material dispensing performed by the controller 35B).

Based on the material warehousing schedule data, the process computer issues a warehousing instruction from the material warehouse to the racks of the automated warehouse (510). In the automated warehouse, based on the warehousing instruction, a predetermined negative number of materials are received into a predetermined rack (520), and upon completion of the warehousing, the rack inventory file is updated (530).

If there is an emergency change, the process computer changes the processing order, checks whether there is excess or shortage of rack stock, and if there is a shortage, returns to the rack stocking instruction again (540), and if the change is large, returns (returns) to the automated warehouse. Then, the need for material collection is notified on the control panel again. If the changes are small, the process computer instructs the automated warehouse to start. The automated warehouse follows the mountain and village order data, sequentially performs the mountain and village, and updates the rack inventory file.

FIG. 19b shows the processing of the shaped steel parts processing line apparatus 34A and the cut plate parts processing line apparatus 35A. These processing line devices transport materials from automated warehouses to forests.
Since there are variations in the length and width of each material, measurements are taken using a length measuring machine (590), and peak marks (part IDs), marking lines, etc. are marked on the material so that the worker can identify the piece after cutting. Print alignment marks (600). Next, the material is cut into pieces according to the cutting length or cutting path (610/620). Next, according to the bevel processing data and the end processing data, the edge of the piece is beveled and irregularly cut (620/630). Next,
Follow the perforation route on each part of the piece and perform perforation (
630, 610).

Next, small parts prepared in advance are welded to predetermined alignment mark positions (640). Then, the finished parts are sorted into assembly sections and stocked in racks (650). Note that edge processing, drilling, and small assembly processes may not be performed depending on the part specifications.

Moreover, in FIG. 19b, the information in parentheses indicates the case of laser processing of a steel plate (cut plate).

FIG. 19c shows the subroutines 600 to 63 of FIG. 19b.
An example of gas cutting of a steel plate with a treatment of 0 is shown below.

In this case, when cutting the material, marking/cutting data is written to a portable controller, and this controller is used as the PI of the processing equipment (marking/cutting machine) on the line.
701), and set the material loading order so that the same cutting pattern continues (702). Next, the cutting pattern is read from the ID of the material to be charged, and the NC data is set (703). 704 The operator uses an overhead crane etc. to set the material on the cutting machine surface plate.
), set the start point of the marking/cutting machine (705), set the driving conditions on the operation panel, and press the start button to start marking/cutting (705).
06), as long as the cutting pattern of the next material does not change, return to the material set (704) and repeat, but when the pattern changes, return to the NC data set (703) and repeat.

Next, when drilling or beveling each cut piece, the cut plates are lined up so that the same piece mark continues, and the NC data of the piece mark of the cut plate to be processed is set (709° 710). When the operator manually sets the cut plate on the processing machine (711), sets the start point of the drilling/beveling machine, sets the driving conditions on the operation panel, and presses the start button, the drilling/beveling machine starts.
Start beveling (712), and as long as the next piece mark does not change, return to the next cutting plate set (711) and repeat, but when the peak mark changes, return to the NG data set (710). repeat.

〔Effect of the invention〕

As described above, according to the present invention, the design drawing procedure is replaced with the actual processing procedure from the design stage (CAD system), and the actual data is processed to automatically design a complete form from the manufacturing point of view. Most of the input data is created automatically. Therefore, it is possible to greatly save the labor of inputting data into the CAM system and the unnecessary repetition of processing due to omissions or mistakes in reading from the design drawings, and it is also possible to prevent production errors. - On the other hand, the machining procedure is described in elemental and generalized manner for each member end around the node, or if it cannot be generalized, the machining procedure and standard dimensions of the joint are made into a cassette as a special joint, for each node. In addition, the dimensions of the end joints of each member are standardized for the parts where the section steel is used, and these are combined arbitrarily and processed for each node, allowing for a variety of designs. In addition, past results are stored not as drawing data, but as standard value files of design data or cassette programs and standard value files that store processing procedures and data for special shiiguchi, making it easy to reuse past know-how. Moreover, it is easy to customize by simply replacing the standard values, and it is possible to efficiently correspond to a variety of designs.

Through this integrated CAD/CAM system, NC lines are created according to CAD/CAM data, material type, and processing characteristics.
Controlled machining and batch-based NC-controlled machining can be flexibly combined, making it possible to automate the high-mix, low-volume production of steel frame parts that can accommodate a variety of diversified structures while maximizing the effects of standardization. It also makes production management easier.
