Description

The present invention, a single product by integrating a large number of companies is a production base to allow production, and as a manufacturing history of each member, each of the companies have manufactured in charge can easily be traced and collectively Related to the integrated production system.

  Large products that require a very large number of parts, such as aircraft, are completed by collaborators from a number of companies that branch off from aircraft manufacturers into pyramids. On the other hand, each component requires extremely high reliability.

  For this reason, in the past, companies that manufactured each part independently stored so-called manufacturing histories such as the manufacturing process and quality inspection method of the part in documents and computer storage devices. It was almost impossible to provide the manufacturing history of the data, and it was impossible to provide it as data having consistency and continuity.

  In particular, SMEs only produce smaller parts or elements of parts, and only passively manufacture parts according to instructions from the parent company, and make their own parts proposals. There was no active participation in manufacturing.

  Furthermore, many companies have a level that requires advanced technology such as aircraft and want to enter the technical field, but do not have a certain type of connection, and therefore cannot participate in parts manufacturing.

Therefore, the problem of the present invention is that any company can freely participate, can be produced consistently by arbitrarily combining companies according to products, and its complete manufacturing history can be traced quickly and easily. Is to do so.

In order to solve the above-described problems, the present invention provides a server in which data relating to the manufacturing histories of the members at a number of production bases that manufacture members, which are component parts of the components, are collected, and the server is accessed to place an order. In the integrated production system of parts comprising a personal computer having a program for allocating the parts of the produced parts to the production base and integrating the parts for manufacturing,
The server has a database in which names of individual production bases and at least names, materials, manufacturing processes, and inspection methods of members manufactured by the bases are registered, and the computer includes at least design drawings and specifications of ordered parts. A member table in which at least the name and material of each component member that has been disassembled into the members that are composed of the letters is input is stored, and the program sequentially retrieves the data of each member of the table, searches the database, and the same Means for searching for a member, means for extracting at least a base name, a manufacturing process and an inspection method of the member when the same member exists in the database, and storing the same corresponding to each member of the table; When the search is completed for all members, the table and all the data stored corresponding to each member are stored. Characterized in that it comprises a means for outputting a granulation history data file.

After said searching for all members of the table is complete, it is possible to provide a means for confirmation to the production facilities to be produced members listed in this table. Moreover, the company group which manufactures the said member can participate arbitrarily. Furthermore, the manufacturing history data file at least vendor has become accessible.

According to this invention, a member table that is a component part of a part is created from a design drawing or a specification of the ordered part, and a database of production bases that manufacture various members based on this table is searched, the order part extracted combinations multiple production sites that can be productive, and since the output as manufacturing history data file so attached to the member table well as production process and inspection process of those members, different variety An integrated production system can be created according to the ordered parts, and the manufacturing history of the ordered parts can be easily and reliably taken out as a whole as a whole by simply accessing the file.

It is a diagram which shows the outline | summary of the integrated production system by multiple companies of this invention. It is a longitudinal section showing a hydraulic pump which is an ordered part. 5 is a flowchart showing computer processing in the system of the present invention. It is a chart which shows the data format of a member table. It is a chart which shows the registration data format of a database.

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the integrated production systems, any, formed mainly SMEs group, interposed between the participating companies A ₁ ... A _n, Inc. as the production bases, and ordering company 30 for ordering parts Te, analyzes the ordered part, consisting of a network connecting the three parties of the participating companies a ₁ ... cooperative integration center 10 to integrated management as a _n company was appropriate linkage can consistently produce.

Participating companies A ₁ ... A _n company is able to participate in any, may be a company related to software is not limited to the manufacturer. Each participating company A _n company registers the products manufactured to the center 10. As shown in FIG. 5, the registered items include not only the company name but also the product name, material, manufacturing process, inspection method, quality control method, and the like. Among these, the product name is registered with a unified name. For example, in the aircraft industry, aircraft manufacturers produce standards with uniform names, and product names are used according to the dictionary. Of course, other unified names, for example, names according to JIS standards may be used. Registration method may be sent may be employed communication means such as a personal computer or a cellular telephone with the participating companies A _n company, or a document to the center 10.

Center 10 includes a server 20, stores the data from the participating companies A _n company database 21. Further, the center 10 receives an order for a product (part) from the ordering company 30 and proposes a new product (part). At that time, by virtue of computer programs center 10's, analysis of products, performing such allocation to participating companies group A ₁ ... A _n.

  The program is loaded on a personal computer or the like operated at the center 10.

  Now, for example, it is assumed that a hydraulic pump 40 as shown in FIG. The hydraulic pump 40 is housed in a housing 41 such that a cylinder block 43 that holds a plurality of pistons 42 at a predetermined interval is rotationally driven by a drive shaft 44. 45 is attached so as to be swingable in all directions, and the shoe 45 is slidably connected to a yoke (swash plate) 46. As the cylinder block 43 rotated by the drive shaft 44 rotates, the plurality of piston shoes 45 slide while closely contacting the yoke (swash plate) 46, so that each piston 42 moves in its axial direction, The pumping action of discharging or sucking oil in the cylinder is performed by changing the volume of each cylinder of the cylinder block 43.

As shown in FIG. 3 while watching the drawings and specifications of the hydraulic pump 40 as described above, is decomposed in the members constituting the hydraulic pump 40 in step S _1, as shown in FIG. 4 is inputted to the personal computer A new member table is created and stored in the memory. At this time, each part of the component is often functionally expressed in the design drawing or the specification (for example, a housing or a cover), so that it is necessary to change to the above-described unified name at the time of input. This would be difficult except by operator input. Others can be input by, for example, an optical reader. In addition, if data such as design drawings and specifications is transmitted from the ordering company 30 via a storage device format such as a disk or a memory stick or the Internet, it is input as it is to create a member table, and the missing part Can be supplemented manually. Note that the minimum unit of members in the member table is preferably set to the same level as, for example, JIS machine elements. Furthermore, it is better if the drawing of the member can be input.

When the member table is completed, pull the data one by one member of the member table in the order in step S _2, it searches the database 21. The search key is preferably a unified name and material of the member. It is preferable to search all databases. If the same member and the same material are found by this search (step S ₃ ), as shown in the lower part of FIG. 4 in step S ₄ , the corresponding company name and the product process and inspection registered in the company database 21. All data such as methods and quality control methods are extracted and attached to the corresponding column of the member table for storage. There may be a plurality of companies that can manufacture the same member. In that case as well, data such as the manufacturing process is taken out for each company and attached to the corresponding member.

When the search is completed for all the members of the table created in the initial step S ₁ (step S ₅ ), the contents of the table are notified to each company listed in the table by e-mail as necessary, and whether or not the manufacturing is possible. You can get permission from the company. Of course, this operation can be automatically performed by the program if only the mail address of each company is registered. If there is an answer indicating that manufacture is not possible, it may be deleted from the member table or set a flag.

Thus the completed final member table, and writes the manufacturing history data file 22 consisting of storage device such as a hard disk at step S _7. Of course, you can print it out. Needless to say, the header when writing to the data file 22 is an ordered part name, an order number, a design drawing, a specification, or the like.

Wherein when searching the database 21 in step S _3, if the missing member may be re-search similar products obtained by slightly changing either or both of the unified name and the material of the member. If you can find in it, may be registered in the member table may be confirmed at step S _6. If it cannot be found by re-searching, you must consider outsourcing to companies other than the participating companies, but in any case this is extremely exceptional. It is assumed that it can be procured.

The above-described processing steps S _{1 to} S ₈ have been described on the assumption that parts have been ordered. However, the cooperative integration center 10 can develop a part as a new product and propose it to the company 30. Again, it is possible as in the case where there is ordered from the company 30, on the basis of the pre-designed drawings and specifications, previously subjected to the process of step S ₁ to S _8.

By producing a member company specified is designated based on the data file 22 created as described above, it becomes possible consistent production of components that are ordered to assemble each member one In order to finish a single part, a company having an assembly line and a collection / delivery yard may be established. Original purpose of cooperation integrated center 10, a number of voluntary corporate group completed by consistent production of particular parts by selecting a particular company, a production history for retaining its quality quickly and reliably It is to be obtained.

In this way, the designated company manufactures the designated member based on the data file 22, so that the material, specifications, manufacturing process, inspection method, quality control method, etc. registered in the data file 22 are obtained. That is, it becomes a manufacturing history. Thus by accessing the data file 22, so that can be traced to the manufacturing history of certain parts Batch.
