FIG. 13 shows that the information management device 30 sends the fixed order information to the output data management device 50 and also sends the second drawing information request signal to the drawing management device 40. Further, it is shown that the drawing management device 40 transmits the second drawing information to the output data management device 50.

Then, it is judged by the function of a predetermined program of the data processing unit 501 whether or not the fixed order information and the drawing information corresponding to each other are gathered. When it is determined that the firm order information and the drawing information are complete, a predetermined program is operated to transmit the firm order information / drawing information as a set of information from the transmitting / receiving unit 506 to the order receiving terminal 60 via the Internet 70. To do. In this way, each information is once sent to the hard disk 205.
Since the fixed order information transmitted from the information management device 30 and the drawing information transmitted from the drawing management device are received at different timings, the fixed order information and the drawing information are stored on the Internet. Via 70,
The fixed order information / drawing information can be integrally transmitted to the order receiving terminal 60.

The overall operation procedure will be described below with reference to FIGS. FIG. 8 shows a schematic operation procedure from creation of quotation request information to decision of order. First, in the production / technical department, an engineer uses a drawing creation device such as CAD to create a drawing of a processed part, and transfers the drawing data to the drawing management device 40 via the network (step 801).
Note that the drawing data here may be any data such as vector format or PDF format as long as it can represent the drawing. On the other hand, the person in charge creates the specification information as shown in FIG. 10 including the information necessary for creating the processed parts by the information management device 30 (step 802).

Then, the information management device 30 transmits the created specification information of the parts to the intermediate data management device 20 and a first drawing information request signal to the drawing management device 40 (step 803). The drawing information request signal requests the drawing management device to read the drawing information corresponding to the specification information. When the drawing management device receives the first drawing information request signal, the drawing management device receives the hard disk 405 (hereinafter, memory 405) based on the drawing number included in the drawing information request signal.
Then, the corresponding first drawing information is read out and transmitted to the intermediate data management device (step 804). When steps 801 to 804 are repeated, a plurality of drawing information and a plurality of specification information are stored in the hard disk 705 (hereinafter referred to as memory 705) of the intermediate data management device 20.

At this time, since there is a difference in the time required to create the drawing information and the specification information, it is general that the quantity of drawing information and the quantity of specification information stored in the memory 705 are different. Next, the intermediate data management device 20 reads the specification information stored in the memory 705 and the drawing information corresponding to the specification information, and sets them as a set to the quotation management device 1
0 (step 805).

As described above, the intermediate data management device 20 is provided for transmitting the drawing information and the specification information received at different times as a set (pair) to the quotation management device 10. The quotation management device 10 receives the drawing information and specification information transmitted in step 805 as a set and stores them in the hard disk 105 (hereinafter referred to as the memory 105) (step 806). The quotation management device 10 executes a predetermined program to create quotation request information based on the specification information (step 807).

The relationship between the specification information and the estimate request information is only different in some data as described above. When the creation of the estimate request information is completed, the estimate request information is stored in the memory 10
5 (step 808). The drawing information and the estimate request information are linked by the drawing number as described above.
Therefore, at this stage, it is preferable that the drawing information and the estimate request information already stored in the memory 105 be set and stored in an appropriate memory area in order to increase the reading speed later. In order to browse and obtain the quotation request information and drawing information created in step 808, the trader activates the order receiving terminal (eg, personal computer) 60 to bring up the browsing screen.

Then, a predetermined operation is performed on the browsing screen to access the quotation management device 10 via the Internet. Then, it requests the transmission of the menu screen data and the quotation request information / drawing information stored in advance in the memory 105 of the quotation management device 10 (step 809). The menu screen data here is assumed to represent, for example, a plurality of quotation request information in a list format. In response to step 809, the quotation management device 10 causes the menu screen data and quotation request information /
The drawing information is transmitted to the order receiving terminal (step 810). The trader, looking at the received menu screen data display, specifies the quotation request information of the processed part of interest on the screen (step 811).

The quotation management device 10 transmits the quotation request information / drawing information of the processed part designated in step 811, and the order receiving terminal 60 displays or prints out the received quotation request information / drawing information (step 812). The trader confirms the content of the quotation request information / drawing information displayed or printed out and decides whether to apply for the quotation. When applying for a quotation, the quotation reply information is input from the display screen, the quotation reply information is created and transmitted to the quotation management device 10 (step 8).
13). The quotation management device 10 receives the quotation reply information sent from the order receiving terminal 60, stores the quotation reply information in the memory 105 by classifying the quotation reply file or the quotation request slip number file (step 814). If the quotation answer information is managed separately for each file in this way, it is convenient for later management.

The person in charge of the quotation request compares the quotation reply information returned from the vendor and determines the most appropriate processor as the ordering party. Then, the order determination information is created and transmitted to the intermediate data management device 20 (step 815). This order determination information serves as the basic information of the confirmed order information created later. As described above, in the present invention, the quotation request information and the drawing information corresponding to the quotation request information can be transmitted as a set to the order receiving terminal 60 of the vendor. Therefore, the trader can quickly and accurately determine whether or not the processed parts are manufactured by referring to the drawing information at the time of considering the quotation application without making a mistake.

FIG. 9 shows a procedure from determining the ordering party to obtaining the firm order information by the trader. The order determination information transmitted from the quotation management device 10 in step 815 described above is once received by the intermediate data management device 20. The received order decision information is transmitted to the information management device 30,
The information management device 30 receives the order determination information (step 901). In the information management device 30, the person in charge creates fixed order information based on the received order determination information and stores it in the hard disk 305 (hereinafter referred to as the memory 305) (step 902). The information management device 30 transmits the confirmed order information to the output data management device 50 (step 9).
03). At this time, in order to read the drawing information corresponding to the confirmed order information from the drawing management device 40, the information management device 30 transmits a second drawing information request signal to the drawing management device 40 (step 904).

When only the firm order information is transmitted to the trader, it is not necessary to transmit the drawing information request signal, but the present invention is characterized in that the firm is provided with the firm order information and the drawing information. Have. The drawing management device 40 reads the drawing information stored in the memory 405 based on the drawing number included in the received second drawing information request signal. Then, the read drawing information is transmitted to the output data management device 50 (step 905).

The output data management device 50 sets the received fixed order information and drawing information as a set to the hard disk 505.
(Hereinafter, referred to as memory 505) (step 90)
6). The output data management device 50 transmits the fixed order information and the drawing information stored in the memory 505 as a set to the order receiving terminal 60 of the contractor of the processed parts (step 907). The order receiving terminal 60 of the order receiving company receives the confirmed order information and the drawing information (step 908). The contractor has confirmed order information,
The contents of the drawing information are displayed or printed out to confirm the contents (step 909). As described above, according to the present invention, in addition to the firm order information which is the final processed part information, the drawing information corresponding to the firm order information can be provided to the trader.

Further, even if the machining parts are changed after the quotation request, the latest drawing information of the machining parts can be provided to the trader by replacing the drawing number when the fixed order information is created. Specifically, it is effective when there is a change in the drawing data used at the time of requesting an estimate, and includes the drawing number of the replacement drawing (for example, a version number that has been upgraded) when the firm order information is created by the information management device 30. By transmitting the drawing information request signal to the drawing management device 40, the replacement drawing information can be read and the changed drawing data can be transmitted.

Further, the precision (data resolution) of the drawing data provided together with the quotation request information and the drawing data provided together with the confirmed order information can be made different. For example, if the accuracy of the drawing data provided at the time of requesting quotation is good, a drawing data format with a low accuracy is used in consideration of the transmission speed, and the drawing data format provided with the firm order information has a highly accurate drawing data format. Can be adopted. In some cases, the order may be reversed, or the drawing data corresponding to the quotation request information and the fixed order information may have different compression rates.

In the above embodiment, the intermediate data management device 20 is arranged between the information management device 30 and the quotation management device 10. The intermediate data management device 20 takes the consistency between the timing of receiving the drawing information and the timing of receiving the specification information and sets the two information as a set.
Has a role to send to. Therefore, the function of this device may be provided in the quotation management device.

In the above embodiment, the drawing management device is described as one unit, but the present invention may be configured by connecting a plurality of drawing management devices to the network as shown in FIG. In this case, the drawing management device is installed in each factory and technical department, and the terminal (PC, etc.) of the information management device is installed in each department in pair with the drawing management device.
