DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a parts ordering system using three-dimensional CAD according to the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram of the present embodiment. In this figure, reference numeral 1 denotes a three-dimensional CAD, 2 denotes an automatic ordering device, and 3A to 3C denote terminals. 3D CAD1
Is for generating and outputting arrangement table data of components constituting a structure based on design data of the structure such as a plant.

Here, a general three-dimensional CAD is for designing a three-dimensional shape of a structure or a component constituting the structure and storing the design data. The three-dimensional CAD 1 of the present embodiment has a structure. The attributes of various parts constituting the object are also registered as part of the design data. For example, design data relating to the three-dimensional shape of a piping structure of a plant includes, in addition to the three-dimensional shape data of various parts (straight pipe, bent pipe, elbow, piping support member, etc.) constituting the piping structure, Various attribute data such as the component name, material, name of a deliverable component maker, delivery mode (container), delivery location (pallet), and the like of various components are included.

The three-dimensional CAD 1 extracts data necessary for ordering various parts constituting the piping structure from such attribute data, for example, part names, order quantities, containers and pallets, and converts the arrangement table data. Generate.

The automatic ordering device 2 is a component maker (company A, company B,
C) automatically generates estimation request data for each component, transmits the request to each terminal 3A to 3C of the component manufacturer of the various parts via a communication line, and receives estimation response data for the estimation request data from the terminals 3A to 3C. Is what you do.

In the automatic ordering apparatus 2, maker data of a part maker for each part is registered in advance for one or a plurality of companies. The maker data includes an e-mail address in addition to the maker name, address, telephone number, and fax number. The automatic ordering apparatus 2 generates estimation request data for each part maker based on the maker data, and transmits the data to each part maker as an e-mail.

The terminals 3A to 3C are provided by respective component manufacturers (Company A,
(Company B, Company C), which receives an e-mail regarding the above-mentioned estimate request data and transmits an e-mail of estimate response data to the estimate request data to the automatic ordering apparatus 2.

Next, a time-series operation of the embodiment constructed as described above will be described with reference to a flowchart shown in FIG. This flowchart shows a series of processing operations of the automatic ordering apparatus 2.

First, the automatic ordering device 2 has a three-dimensional CAD 1
, The control parameter i indicating the part number is set to "1" (step S2). Usually, since a structure such as the above-mentioned piping structure is composed of a plurality of parts, a plurality of parts are indicated as arrangement targets in the order sheet data. By setting the control parameter i to "1" in step S1, the part having the part number 1 on the order table data is selected as the first processing target.

Subsequently, the automatic ordering apparatus 2 checks and extracts the part maker having the part number 1 by referring to the maker data (step S3). That is, in step S3, one or more component manufacturers registered in advance as deliverable manufacturers of the component corresponding to the component number 1 are extracted. When the part maker of the part corresponding to the part number 1 is extracted in this way, the automatic ordering apparatus 2 increments the control parameter i (step S4), and selects the part corresponding to the part number 2 as a processing target. .

If the part number 2 is not the last part on the order table data (step S5), the processes of steps S3 and S4 are repeated to obtain the parts of all parts on the order table data. Extract manufacturers. When the extraction of a part maker for one piece of order table data is completed in this way, the automatic ordering apparatus 2 generates estimation request data for each extracted part maker, and transmits it as an e-mail to the terminals 3A to 3C of the part maker. (Step S
6).

For example, if three parts manufacturers (company A, company B, company C) are registered for the same part in the automatic ordering apparatus 2, the request for the parts is sent to the company A, company B and company C for estimation request data. Will be sent. The companies A, B, and C respectively create estimate response data for the estimate request data and return them as e-mail to the automatic ordering device 2, which then returns the estimate response data. Receive (Step S7). Then, the orderer operating the automatic ordering apparatus 2 separately purchases a part by sending a purchase table for requesting the delivery of parts to Company C, for example, which has returned the cheapest estimate response data.

According to the present embodiment, since the estimate request data is automatically generated and transmitted for each component maker (company A, company B, company C) corresponding to the component, a plurality of component manufacturers (company A) , Company B, Company C) can be requested efficiently. In addition, since the estimate response data for the estimate request data is received from the component maker via the communication line, the orderer can obtain the estimate response from a plurality of component manufacturers more quickly than by mail or the like. Furthermore, since e-mails that are widely used at present are used as means for sending and receiving estimation request data and estimation response data, system construction is easy.

In the above embodiment, the automatic ordering device 2
Has been described in the case of ordering parts from a part maker registered in advance, but such parts maker is trusted by the ordering party in terms of parts production capacity and quality, etc., and continuously performs ordering of parts. It is a certified manufacturer. However, for general parts, it is not always necessary to limit the suppliers to authorized manufacturers. As for parts that do not need to be limited to authorized manufacturers in this way, by posting the data of the parts to be ordered on a website on the Internet, it is possible to collect quotes from more parts manufacturers and purchase parts. You may do it.

Further, some parts, such as "valves", are determined by the part maker to determine the shape and dimensions and delivered to the supplier. It is also conceivable that the automatic ordering device 2 receives the shape and dimension data of such a part via a communication line and outputs the shape and size data to the three-dimensional CAD 1 from the automatic ordering device 2 to assist in the design.

In the above embodiment, the purchase table is separately sent to the parts maker to purchase the parts.
That is, the automatic ordering apparatus 2 does not automatically process even the shipping of the purchase table. The reason for this is that the actual selection of the component maker is determined in consideration of not only the estimated amount but also various conditions, and it is necessary for human judgment to be involved. However, for parts that can be selected simply based on the estimated price, for example, the estimated price of each component manufacturer is compared by the automatic ordering device, and the purchase table is automatically sent to the component manufacturer with the lowest estimated price. You may do it.

[0025]

As described above, according to the third embodiment of the present invention,
According to the parts ordering system using the dimensional CAD, the order table data is automatically generated based on the design data and transmitted to the parts maker, so that the efficiency of parts ordering can be greatly improved as compared with the related art. It is possible.
