123, etc.).

This prior art is a drawing generation device that stores drawing information of a plurality of types of products having similar shapes in a storage means and generates a drawing based on the drawing information read from the storage means. When storing, the drawing information of each product is classified into shape information indicating the shape of the product, parameter values common to each product, and parameter values different for each product. In addition to saving the shape information of these, the parameter values common to a plurality of products are stored as a set of common parameter information, and the parameter values different for a plurality of products are the parameter values of each product in the parameter table information. It is supposed to be saved as.

When the drawing information is read to generate the drawing, the shape information, the common parameter information, and the parameter table information that are stored are read to generate the drawing.

[0005]

However, in the above-mentioned conventional drawing generation apparatus, it is necessary to design and draw the parameters representing the product shape for each product group based on the basic shape, and to express the shape. Since it is necessary to set the parameters to be set, it cannot be said that the labor and the design time of the designer are sufficiently reduced.

Further, since the items having the same number of parameter items are handled, and the totalizing function is not applied to the component groups having different number of parameter items, they are excluded from the targets of the totalizing chart at the first stage. There was a problem that it ended up. That is, there is a problem that the number of managed drawings is not necessarily an efficient number.

The present invention was devised to solve such a problem, and the purpose thereof is to be able to create a component drawing with as little labor and time as possible and to use an efficient number of drawings. An object of the present invention is to provide a device for creating a developed parts drawing of an assembled product capable of managing drawings.

[0008]

In order to solve the above-mentioned problems, a device for creating a developed part drawing of an assembled product according to the present invention has a plurality of types composed of position information, direction information, and parameter information representing dimensions in each direction. And a basic shape information storage unit that stores basic shape information of a plurality of types of parts that are included in the basic shape information storage unit when the assembly drawing of the assembled product is created.

FIG. 7 shows a format for storing such a basic shape.

Next, a procedure for creating each part drawing from the assembled product shown in FIG.

The assembled product shown in FIG. 2 is a kitchen lower box, and includes a right door 31, a left door 32, a right side plate 33, a left side plate 34, a bottom plate 35, a back plate 36, a curtain plate 37, a contact plate 38, and a handshake 3.
It is composed of 9 parts and the like.

Therefore, the component shape information creating unit 12 first creates the component shape information of the right door 31 in accordance with the input from the information input unit 13. FIG. 8 shows the right door 31 taken out from the assembled product, and the dimensions of each part are as entered in the figure.

From the drawing of the right door 31 shown in FIG.
The right door 31 has one cube basic shape of basic shape number 1,
It can be understood that a total of seven basic shapes can be expressed by combining two basic shapes that represent the cylindrical hole having the basic shape number 2 and four basic shapes that represent the corner R having the basic shape number 4.

Therefore, in the part shape information creating section 12,
According to the input from the information input unit 13, the parameter information of the basic shape information of the basic shape numbers 1, 2, and 4 stored in the basic shape information storage unit 11 includes the vertical, horizontal, and thickness values shown in FIG. And the like, the distance from the reference position is written in the position information, and the x, y, and z directions are written in the direction information, respectively, and stored in the component shape information storage unit 15.

FIG. 9 shows basic shape information of the right door 31 expressed by the combination of parameters of each basic shape.

In the component shape information creating unit 12, the left door 32, the right side plate 33, the left side plate 34, the bottom plate 35, the back plate 36, the curtain plate 37, and the contact plate 3 according to the input from the information input unit 13.
8. Basic shape information of the handshake 39 is sequentially created and stored in the component shape information storage unit 15.

Therefore, the lower kitchen box composed of these parts 31 to 39 can be expressed in the format shown in FIG.

When all the basic shape information of the parts has been created in this way, the parts drawing creation unit 16 starts counting the parts in accordance with the totaling instruction from the information input unit 13.

The counting procedure will be described below with reference to the flowchart of FIG.

That is, the part drawing creation unit 16 reads the part shape information of each of the parts 31 to 39 forming the lower kitchen box from the part shape information storage unit 15 (step S1),
The read combinations of the basic shape numbers of the respective parts 31 to 39 are compared (step S2). Then, if the number of constituents of the basic shape and their combination match, the operation proceeds to step S3. If the number of constituents of the basic shape and their combination do not match, one item uniform drawing is created for the mismatched parts. Yes (Step S
8).

For example, when the basic shape information of the right door 31 and the basic shape information of the left door 32 shown in FIG. 10 are compared, the number of basic shape components is the same for both 7, and the combination is also the basic shape. The number 1 is common to one, the basic shape number 2 is two, and the basic shape number 4 is four. Therefore, in step S2, the right door 31 and the left door 32
Is determined to be a part having the same number of basic shapes and the combination thereof.

Although not shown, the right side plate 33
The left side plate 34, the bottom plate 35, and the back plate 36 are also determined to be the same parts.

In step S3, the arrangement directions of the basic shapes are compared next. Then, if the arrangement directions do not match, a one-item uniform drawing is created for the mismatched parts (step S8).

On the other hand, when the directions match in the comparison in step S3, the matched parts are counted as one group.

For example, comparing the right door 31 and the left door 32, which are determined to have the same number of basic shapes and their combinations, as shown in FIG. 10, the direction information is the same in each basic shape number. . Therefore, the right door 31 and the left door 32 are totaled as one group.

Further, in the totaling operation, the position information in the x direction of the cylindrical hole indicated by the basic shape number 2 of the right door 31 (serial numbers 2 and 3) and the basic shape number 2 of the left door 32 are indicated. Since the position information in the x-direction (for serial numbers 2 and 3) of the columnar hole is different (the right door 31 is 50 and the left door 32 is 550), in this case, as shown in FIG. ,
The common parameters are extracted (step S4), and a totalized part drawing defined by the representative shape and the parameter table to which the common parameters are added is created (step S4).
5, S6, S7).

Therefore, the totalized component drawings made into drawings by the drawing output unit 17 are each a plan view, a front view, and a side view.
The form is a combination of a plan view and a parameter table in which the formation positions of the cylindrical holes are displayed as parameters.

FIG. 13 shows a flow chart for explaining the counting procedure when the number of parameters is not the same.

For example, as shown in FIG. 14, when only the right door 31 has a hole-shaped recess, the shape information of each of the parts 31 to 39 of the kitchen lower box is as shown in FIG. The right door 31 and the left door 32 have different numbers of basic shapes.

Therefore, the part shape information of each of the parts 31 to 39 forming the lower kitchen box is read from the part shape information storage section 15 (step S11), and the combination of the basic shape numbers forming the read parts 31 to 39 is read. When the comparison is made (step S12), the right door 31 and the left door 32
Means that although the combinations are almost the same, some of them do not match.

In this case, in step S13, the arrangement directions (direction information) of the basic shapes having the same combination are compared. That is, the serial number 1
The direction information of the basic shapes up to 7 will be compared.

In this case, since the right door 31 and the left door 32 have the same basic shape direction information (see FIG. 15), the right door 31 and the left door 32 are aggregated as one group.

In addition, in the totalizing operation at this time, positional information in the x direction of the cylindrical hole indicated by the basic shape number 2 of the right door 31 (serial numbers 2 and 3) and the basic shape number of the left door 32. The position information in the x direction of the cylindrical hole indicated by 2 (with serial numbers 2 and 3) is different (50 for the right door 31, 32 for the left door).
Is 550) and the serial number 8 of the right door 31
Since there is no basic shape information in the part shape information of the left door 32, in this case, as shown in FIG. 16, common parameters are extracted (step S14), and the representative shape and parameter table with the common parameters added thereto are added. A total parts drawing defined by and is created (steps S15 and S1).
6, S17).

Further, the basic shape information of the serial number 8 which is the difference between the two parts is created as a detailed difference shape diagram (special shape) (step S18), and the difference shape exists in the remarks column of the parameter table. Is added (step S
19).

Therefore, the totalized component drawings made into drawings by the drawing output unit 17 are each a plan view, a front view, and a side view.
This is a form in which a plan view, a parameter table in which the formation positions of cylindrical holes are displayed as parameters, and a differential shape detailed view are combined.

As described above, according to the unfolded-part drawing creating apparatus of the present invention, the parameters representing the basic shape prepared in advance become the parameters of the parts handled at the time of creating the part drawing. There is no need to re-classify the parameters so that they are parts and are subject to the aggregate drawing. In addition, since the parameters are expressed for each basic shape, even if the number of parameters is not the same for each component to be aggregated, the difference is treated as a difference shape detailed diagram, and the aggregated drawing is created using only the parameter table. It is possible to collect more similar parts and express them in drawings.

[0054]

As described above, the apparatus for creating a developed part drawing of an assembled product according to the present invention stores basic shape information storing a plurality of types of basic shape information composed of position information, direction information, and parameter information representing dimensions in each direction. Means and the assembly shape of the assembled product, the information expressed by the combination of the plurality of types of basic shape information stored in the basic shape information storage means is used as the part shape information of each part constituting the assembled product. Part shape information storage means for storing and storing the actual value at the time of drawing in the parameter information of the combined basic shape information, and the part shape information at the time of creating the part drawing in which the assembled product is developed. Based on the component shape information for each component stored in the storage means, the stored component combination information of the basic shape and the component having similar direction information and similar components are stored. Parts are aggregated as one group, and if similar, the shapes of a plurality of similar parts are represented by a representative shape with common parameters and a parameter table, or a difference between representative shapes and parameter tables with common parameters and aggregated parts. Since the configuration is provided with a component drawing creation means that is represented in the drawing by the detailed shape of the shape that becomes, the parameter that represents the basic shape prepared in advance becomes the parameter of the component that is handled when creating the component drawing, There is no need to perform the work of setting parameters again so that each component is a similar component and is the target of the aggregated drawing. In addition, since the parameters are expressed for each basic shape, even if the number of parameters is not the same for each component to be aggregated, the difference is treated as a difference shape detailed diagram, and the aggregated drawing is created using only the parameter table. It is possible to aggregate and represent more similar parts. As a result, it is possible to create a component drawing with less labor and time and with an efficient number of drawings than those of the prior art.
