Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing information automatic generation system, and more particularly to a data creation system used in various manufacturing / manufacturing information systems, production management systems, CAM systems, field instructions, etc. in the manufacturing field.

2. Description of the Related Art As a conventional technique, for example, Japanese Patent Laid-Open No.
There is a production line control information automatic generation method described in the 4-372002 publication.

A conventional production line control information automatic generation system comprises a process design system, a production line scheduling system, a production preparation support system, and a production machine database. This method realizes schedule planning and automatic generation of NC data in processing cells from the process design of machined products.

[0004]

The above-mentioned conventional automatic control information generation method for a production line uses various methods such as exchanging data between a process design system using an expert system, a scheduling system, and an NC data automatic creation system. The configuration is complicated by integrating the systems, and it is difficult to manage data such as rule bases because expert systems are used. In addition, the target of control information is schedule, Gantt chart, NC.
Since data is targeted, the disadvantages are that standard data is not provided to other production and manufacturing systems, and that the target is specialized for machined products.

The present invention will be described in detail with reference to the drawings.

FIG. 1 shows a manufacturing information automatic generation system for packaged products according to an embodiment of the present invention. CAD data 1 that is input data of this embodiment and is created by the design department
Has component configuration data and component mounting position data. The package manufacturing information automatic generation system 2 includes a manufacturing information database 3, a process sequence creation processing unit 4, a process information creation processing unit 5, and a cost lead time information creation processing unit 6. Then, the output information includes process procedure data (work process order) 7 for each product, process standard time data (work time for each process) 8, work component data (work components for each process, number) 9, standard lead time, which is the data 10 _{of the} partition original _value. These output data are processed by the data processing unit 1
By processing in 1, the production management system, the production progress management system, the CAM system, the scheduling system, the cost management system, the production / manufacturing system such as the work site instruction, and the reference data of the work site 12 are obtained.

FIG. 2 shows an example of the data format 3 of FIG.
_Indicates . The process sequence master 13 shows basic flow information of each process. In this example, based on the rules of the site,
After the step A, the flow to the step B or C is defined. The process capability master 14 has information on the capability of each process. In this embodiment, the work content of each process,
It has a work element, a unit work time for each work element, and a work unit price for each work element. The parts master 15 has data such as specifications and prices of individual parts.

As an example, a process when the CAD data of the product A shown in FIG. 3 is input will be shown. Product A parts configuration 1
6 includes 50 parts a, 20 parts c. ． ． It is composed of. The process sequence creation processing unit 4 sequentially processes the process capability master 1 from the first process defined in the process sequence master 13.
4 to the list of work elements for each process
It is checked whether 6 exists, and the existing processes are arranged in the order of the process sequence. At this time, the process in which the component does not exist in the work element list is excluded from the process sequence of the product A. As a result, the process sequence of product A is shown in FIG.
The relationship between the process B and the process C in FIG. 4 means that either process can be used because the process capability master 14 has the same work content and the same work element. The process information creation processing unit 5 uses the process capability master 14
From the work content of each process, work time per work element, work unit price, considering the priority such as manufacturing lead time, manufacturing cost, etc., optimize and decide the process series and which work element to perform in which process To do. The priority for this optimization is
It is input as a parameter in advance when processing is executed. In the process in which the work element is a part, the process of arranging the part between the processes is performed, and the work time in each process is calculated. The result is shown in FIG. For example, between steps B and C in FIG. 4, when selecting either step with priority on the short work time, the total time for working 50 parts and 20 parts a and _c in step B is calculated. And 25 (S), while the total time of process C is 37 (S), process B is used. The processing result of the process information creation processing unit 5 is shown in FIG.
Shown in. The cost lead time information creation processing unit 6 is for the product A.
6, the material cost is calculated from the component price of the component master 15 and the component price of the component master 15, and the partition cost of the product A is calculated from the sum of the work price of each process of FIG. 6, and each process of FIG. The lead time of the product is calculated from the sum of the working hours of. As a result, the standard lead time is 1049 (s).
The partition cost is 5940 + 625 = 60025 yen. From the results of the above processing, process sequence data 7, process standard time data 8, process work part data 9, lead time, and cost data 10 are obtained. In the data processing unit 11, these data are processed, transferred, and printed as standard data 12 for various production / manufacturing systems and site-specific data 12.

By making the work contents and work elements of the process capability master 14 various kinds of elements in manufacturing, the same idea can be applied to other manufacturing industries.

According to the automatic manufacturing information creation method of the present invention, since the output data covers all the basic information necessary for production activities, it is possible to use the standard data for various production / manufacturing systems and sites. It can be provided, effective use of existing systems can be achieved, the database model is simple, so maintenance is easy. Based on data from the information design department, various conventional production / manufacturing systems and By performing calculation processing on the same information that was created individually in the field activities collectively, it is possible to eliminate inconsistencies between information, input errors, and optimize processes based on priority. As a result, there is an effect that efficient production activities can be performed.
