Description

  The present invention relates to a system in which a large number of companies can be integrated so that one product can be produced in an integrated manner, and the manufacturing history of each member produced by each company can be easily traced.

  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 is required to have 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. The company did not actively participate 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 participate freely, and it is possible to perform integrated production by arbitrarily combining companies according to products, and to trace the complete manufacturing history quickly and easily. It is to be.

  In order to solve the above problems, the present invention comprises a center for receiving an order for the part interposed between a company for ordering a part formed from an assembly of members and a group of companies for manufacturing the member. The center includes a database in which at least unified names, materials, manufacturing processes, and inspection methods of members manufactured by individual companies of the group of companies are registered, and at least design drawings and specifications of each ordered part. A table storage means for enumerating at least unified names, materials, and specifications; each means for taking out each member in turn from the table storage means; searching the database for the same member; and the same member in the database At least the company name, the manufacturing process and inspection method of the member are extracted and attached to the corresponding member column of the table storage means. And means for outputting all data of the table storage means as a manufacturing history data file when the search is completed for all members of the table storage means. Data communication is possible.

  After all the members of the table storage means have been searched, there can be provided means for confirming with respect to a company that should manufacture the members listed in this table. Moreover, the company group which manufactures the said member can participate arbitrarily. Further, the manufacturing history data file can be accessed at least by the ordering company and the center.

  According to the present invention, a member table that is a component part of a part is created from a design drawing or specification of the ordered part, and a database of companies that manufacture various members is searched based on the table. The combination of multiple companies is extracted so that parts can be produced in an integrated manner, and the manufacturing process and inspection method for those parts are attached to the part table and output as a manufacturing history data file. A system can be created, and the manufacturing history of ordered parts can be easily and reliably retrieved simply by accessing the file.

It is a diagram which shows the outline | summary of the integrated production history trace 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, integrated production history tracing system, any, interposed between primarily the participating companies A ₁ ... A _n company formed from small business group, and ordering company 30 for ordering parts, It 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 may integrated production.

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 a 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 this 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 via 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, extraction one by one member from the member table in step S _2, 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 found of the same member the same material by the search (step S _3), as shown in the lower part of FIG. 4 in step S _4, the corresponding product process registered in the database 21 of the company name and the company, the inspection 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 searching for all members of the table created in the initial step S ₁ is terminated (step S _5), and notifies the contents of the table by email to each company listed in table if necessary, the possibility of manufacturing the 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 manufacturing a specified member by a specified company based on the data file 22 created as described above, it becomes possible to produce the ordered parts in an integrated manner. In order to finish the parts, a company having an assembly line and a collection / delivery yard may be established. The original purpose of the cooperative integration center 10 is to select a specific company from a large number of voluntary participating companies, complete specific parts by integrated production, and quickly and reliably obtain a manufacturing history for maintaining the quality. Is to be able to.

  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. Therefore, by accessing this data file 22, the manufacturing history of a part can be traced consistently.
