  Since Patent Document 1 defines a part corresponding to a symbol in a drawing, the relationship between the position in the product and the design time is unclear, and it becomes difficult to cooperate with the design work. Further, Patent Document 2 creates a design drawing and a design list from input information, but the input information is not standardized. As a result, since the input information becomes a character string, the check takes time.

  An object of the present invention is to provide a design / manufacturing support system that can overcome the above-mentioned problems of the prior art and can automate parts ordering and creation of a design drawing only by selecting a design code. Another object is to provide a new business based on a design / manufacturing order method using a design code. Thereby, the man-hours for design work and parts arrangement work can be greatly reduced, and work leakage can be reduced.

  To achieve the above object, the present invention provides a design / production support system including a computer device that assigns a drawing number to a set of product drawings and stores it as electronic information, and supports automation of product design and production. Product code definition database in which product codes are defined by grouping upper elements to lower elements by component configuration, and each group is associated with upper 1 digit to lower n digits, and the product code definition database is referred to for each product. A design code table in which the product code of each digit is selected according to the specification and the design code is registered, and a drawing definition table in which the created design code is associated with the drawing number of the corresponding product are provided. It is created by referring to the drawing definition table from a design code.

  Or, in a design / production support system equipped with a computer device that supports the automation of product design and production, the high-order elements of the product are grouped by component structure, and each group corresponds to the high-order 1 digit to the low-order n digits. A product code definition database in which product codes are defined, a design code table that refers to the product code definition database, selects a product code for each digit according to the specifications of each product, and registers a design code; and A part database in which the number of digits for each part, product code, specification, and number are associated from a product code definition database is provided, and parts of the corresponding product are arranged by referring to the part database based on the design code. .

  Alternatively, when a plurality of drawings of a product are assigned with drawing numbers and stored as electronic information, and a design / manufacturing method is provided with a computer device that supports automation of product design and production, the specification of the ordered product is received from a client. A design code composed of a plurality of digits in which each element of the ordered product is represented by a code is created, and a drawing is automatically created and / or parts are automatically arranged according to the design code. The design code may be created in advance for a plurality of patterns of products, and the client may select according to the use of the ordered product.

  According to the present invention, it is possible to automate the creation of a design drawing and the ordering of parts by creating a design code. In addition, there is an effect that part ordering can be appropriately managed by design classification.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a business flow of a design / production method according to an example of the present invention. The customer 101 makes a production request 102 to the design / production company 103. The design / production company 103 first performs product design 104 based on the request contents (product specifications) from the customer 101. For design, group the lower elements from the higher elements of the product in advance by component configuration, and create a product code definition database in which the parts are defined in association with each group, and a parts database in which the parts and the number are associated with each product code. .

  Next, when the product code is selected for each ordered product and the design code 105 is created, arrangement information for automatically arranging parts 106 is automatically created 107. Based on this arrangement information, a part order 109 is made to the part maker 108, and the maker 108 sends the part 110. In addition, based on the design code 105, a drawing definition database is created by associating a drawing number of a set of drawings stored in advance for each product with a design code, and a design drawing is automatically created 112 by designating the design code. The product is completed 114 based on the delivered parts 113 and the design drawings, and delivered to the customer.

  As described above, in the product design in the present invention, a product code and further a design code are created from the product specification, and based on this, automatic ordering of parts and automatic creation of a design drawing are performed. The design code may be created by the customer. In other words, it is possible to register design codes for a plurality of patterns of products in advance, and customers can select a design code according to the specifications of the ordered product and request a product from the design / production company. .

  FIG. 2 shows an outline from design to production. A combination of codes, that is, a design code 202 can be created by the designer 201 selecting a product specification (spec) based on the product code definition. The design code 202 is associated with a drawing number, and a drawing definition database is created. After that, the design drawing 203 is automatically created based on the design code. Further, the arrangement information 204 is automatically created based on the design code, the parts are ordered from the parts maker 206 via the arrangement section 205, and the manufacturer 207 manufactures the parts based on the procured parts.

  FIG. 3 shows the flow of processing from design to manufacturing in more detail. After the designer 301 creates the design code 305 based on the product code definition created in advance, the designer 301 transmits the arrangement information automatically created by the arrangement instruction 306 to the arrangement staff 302. The arrangement staff 302 receives the arrangement information (specification document) 307 and places an order 308 for parts to the parts maker 303.

  The parts maker 303 searches 309 for the ordered parts, and if there is no part, reports 311 that there is no inventory to the arrangement staff, and the arrangement staff contacts the designer 312. The designer examines 313 alternatives and the like, and performs design code creation 305 again. If there are parts (310), the parts are sent 314 to the arrangement staff. The dispatched part is received 315 via the arranger 302, and the designer confirms the part (316).

  If the result of the confirmation is that the part is wrong (317), the dispatcher contacts 318 to the part maker, and the part maker searches for the correct part 319 and re-sends (314). On the other hand, if the part is correct, the part is sent to the manufacturer 304 (320). Further, the designer transmits the design drawing created by the design drawing automatic creation instruction 321 to the manufacturer 304. The manufacturer 304, upon receiving the parts reception (322) and the design drawing reception (323), manufactures (324).

  FIG. 4 shows the configuration of a design / production support system according to an embodiment. Here, the processing configuration from design code creation 305 to design drawing automatic creation 321 and arrangement information automatic creation 306 of FIG. 3 is shown. In addition, each terminal of an arrangement staff, a parts maker, and a manufacturer is abbreviate | omitted.

  The design terminal 400 and the server 410 are connected by a network 409. In the design terminal processing device 407, a design code 402 is created through the product design 401, and based on this, the parts arrangement information automatic creation processing 403 and the design drawing automatic creation processing 404 are executed. Each process is executed by exchanging with the server 410 via the network 409.

  The server 410 includes a product code definition database 411, a parts database 412, a drawing definition database 413, and the like, and is referred to from the processing device 407 via the network 409. A design code table and drawings (hard sequence) are also stored.

  First, in order to perform product design 401, the product code information is referred to from the product code definition database 411 and a design code is created. Next, in the parts arrangement information automatic creation processing 403, necessary information is extracted from the parts database 412 based on the created design code 402, and parts arrangement information 405 is created. Further, a drawing definition database 413 is created, and a design drawing automatic creation process 404 extracts a necessary drawing by referring to the drawing definition database 413 based on the design code 402 to create a design drawing 406.

  FIG. 5 shows how a design code is created according to one embodiment. This figure is an example of control panel design. The control panel 501 is grouped by component configuration, product codes are related to the grouped products, and product codes are defined so that the designer can select each digit. A code definition database 502 is provided. The design code creation unit 503 refers to the definition content of the product code definition database 502 and creates a design code having a multi-digit system from the first digit to the n-th digit.

  The parts database 504 stores part information corresponding to the product code, extracts parts from the parts database 504 based on the created design code, and creates a parts arrangement form 505. Since the drawing definition database 506 defines the drawing number corresponding to the design code, the hard sequence is collected by the design code by referring to the drawing number.

  FIG. 6 shows the basic system of the design code. The design code is defined from a rough specification that is higher in the digit to a detailed specification that is lower than the digit to represent the product. Specifically, the product name 601, the product size 602, the outer surface element 603, the inner surface element 604, and the element subdivision 605 are defined. Design division (606) indicates a division in design work and arrangement work (thus related to design / production time), and is defined as 1st to nth in order from the highest digit.

  FIG. 7 shows registration of the product code definition database and selection of the design code of the target product. The number of digits, product code, specification / manufacturer, and design classification are set from the product code definition registration screen 701 and stored in the definition table 703. When the product is a control panel, for example, there are three types of panel sizes in the first digit. Among these, if code A is set for a specification having a height of 2300 mm, a depth of 860 mm, and a width of 900 mm, it is registered in the product product code definition table 703 as in the first line 704. Codes B and C are also set for the other sizes. Similarly, when n digits are set, the specifications for each digit are associated with the product code, and the product code definition table 703 is completed.

  In addition, by setting a design category indicating the design time for each digit, design work according to the design category becomes possible. That is, since the same design category is set in the same digit row, the parts arrangement can be appropriately managed according to this design category. In the product code definition database, product code definition tables 703 for a plurality of product types may be stored.

  After the product code definition database is registered, the design code for the target product can be created. First, product code associations from the first digit to the nth digit are selected and set from the design code selection screen 702. For example, if the first digit is A (height = 2300, depth = 860, width = 900), the spec that can be set in the second digit is 1 (front and back doors), and the spec that can be set in the third digit. If S (both sides) is set and the spec that can be set in the n-th digit is a (AC 100 V, 50 Hz), “A1S... A” is registered in the design code table 705, and the design code of the target product can be selected. .

  FIG. 8 shows a method for referring to a product code in creating a design code. With reference to the product code definition table 802 of the control panel from the product code definition database 801, information from the first digit to the nth digit is displayed for each digit on the design code selection screen (803 to 806). When the first digit is the board height 803, the second digit is the door 804, the third digit is the side cover presence / absence 805, and the n-th digit is the control power supply 806, the respective product codes are displayed as menus as shown in the figure. . Accordingly, when the corresponding product code is selected in order from the upper digit, the selected design code appears on the input screen 807. In this way, by selecting in order from the upper digit, there is no wrong combination, and backtracking work can be prevented.

  FIG. 9 shows features of design code selection. When the product code of each digit is selected from the product code definition database 901, the product code selected at the higher digit limits the product codes that can be selected at the lower digit. For example, when the design code is selected as “A1S... A” 903, if 2300 mm is selected 906 in the first digit, only the back and front doors can be selected 907 in the second digit. When “B1R... A” 904 is selected, since 1900 mm is selected 910 in the first digit, selection 911 can be performed in the second digit for the front and back kannon doors and the front and back single doors. Further, only the right side can be selected 912 in the third digit. Since the same restrictions are automatically displayed for the following digits, design errors can be prevented.

  FIG. 10 shows the data registration procedure of the parts database. On the data registration screen 1001, a registration screen for the number of digits, product code, part name, specification / manufacturer, number of persons, and design category is displayed, and necessary information is defined for each product code of each digit. sign up. The data registration screen 1001 is automatically displayed where the same contents as the product code definition table are displayed.

  FIG. 11 shows a method for automatically creating an arrangement specification. When the created design code 1101 is “A1S... A”, the part name, specification / manufacturer, and number are extracted from the part database 1002 for each product code of each digit. An arrangement specification 1102 is automatically created based on the extracted information.

  FIG. 12 shows the data registration procedure of the drawing definition database. On the drawing data registration screen, a design code and drawing number input screen is displayed, and the drawing (hard sequence) is associated with the design code. For example, when drawing number A is input to design code “A1S... A” and drawing number B is input to design code “B1S... B”, the design code and hard sequence drawing numbers are stored in drawing definition database 1202. Is registered.

  FIG. 13 shows a drawing (hard sequence) registered in the server. Each product is registered with a drawing number assigned to a set of drawings. For example, the drawing number A is composed of a plurality of drawings representing the corresponding product.

  Thus, the drawing can be created by referring to the drawing definition database 1202 and automatically extracting the hard sequence based on the design code. Here, all drawings of an arbitrary product are stored in one drawing number, but it is also possible to store drawings related to common element parts so that they can be shared.
