  Returning to FIG. 1, when the part configuration information, the part information, and the processing information are stored in the design parts table storage unit 12, the input screen generation unit 13 of the parts table creation support apparatus 1 stores these information and the condition storage unit 14. The process information input screen is generated based on the processing condition information and the facility information stored in the process information and sent to the display unit 15. The process information is information indicating what process is performed on the part in which order and how many man-hours are performed with which equipment for each part included in the part configuration information.

  The display unit 15 displays the input screen received from the input screen generation unit 13. The display unit 15 may include a monitor, and may display an input screen on the monitor, or may be transmitted to a terminal used by the designer and displayed on the terminal.

  FIG. 7 is a diagram illustrating an example of the input screen according to the embodiment. When the part configuration information is stored in the design part table storage unit 12, the input screen generation unit 13 refers to the part information of each part included in the part configuration information and inputs process information of all the parts that need to be processed. A screen is generated and displayed on the display unit 15.

  FIG. 7 shows an example of an input screen for inputting process information of the cover A, which is a part constituting the finished product A. The input screen generation unit 13 determines the “name” cover A, “drawing number” abc222, “material” SPCC, “expanded dimension (thickness)” 0.8 mm from the component configuration information and the component information and processing information of the cover A. , “Development dimension (length)” 250.0 mm, “Development dimension (width)” 400.0 mm, “Completed dimension (thickness)” 25.2, “Completed dimension (length)” 220.5, “Completed dimension” (Width) ”345.0,“ Drilling ”25 shots,“ Molding ”4 steps, and“ Painting ”1 step are read out and displayed at the top of the input screen.

  Note that the information displayed on the upper part of the input screen is not limited to this, and at least information for identifying a component is sufficient. Further, the display location is not limited to the upper part of the input screen.

  The input screen generation unit 13 uses the part information and processing information of the cover A, the processing condition information, and the equipment information, and the process candidate that can be performed on the cover A and the equipment candidate that can perform each process. Are extracted and displayed on the input screen in a selectable manner. On the input screen displayed on the display unit 15, the designer selects a process and equipment from the displayed candidates in order from the first process, and inputs the man-hours of the process performed by this equipment.

  In the example of FIG. 7, the designer has selected drilling as the first step, and has selected equipment P1 as the facility for drilling. Moreover, the designer has input 25 as the man-hour of the drilling performed with the equipment P1. When a process and equipment are selected and man-hours are input, the input screen generation unit 13 calculates a tact time for each process from the processing condition information and displays it on the input screen. The takt time is a standard time from when a material is input to the facility until the next process can be started after processing.

  The tact time in the case of performing 25 shots with the equipment P1 is standard work time 2.0 (seconds) × 25 (shots) + setup time 600.0 (seconds) = 650.0 (seconds). Here, since the unit of the tact time is expressed in (minutes), 10.8 (minutes) is displayed.

  By displaying the tact time as the cost for each process, when there are a plurality of candidates, it can be used as a judgment material for the designer to select a process or equipment. Note that the input screen generation unit 13 may calculate not only the tact time but also other costs such as cost and manpower, and may display them on the input screen, or may not display the tact time on the input screen. When the tact time is not displayed on the input screen, the “standard processing time” that is the cost information included in the processing condition information may be omitted.

  Similarly, the designer selects a process and equipment in order of the second process and the third process, and inputs the man-hours of the process to be performed by this equipment. Process and equipment candidates are displayed in a pull-down manner. Since the processing steps performed on the cover A are drilling, molding, and painting, the input screen generation unit 13 displays the drilling, molding, and painting in a pull-down manner.

  For example, when there is a predetermined rule that drilling and molding are always performed before painting, the input screen generation unit 13 may narrow down candidates for the process to be displayed according to the predetermined rule.

  When the designer selects drilling as in the first step, the input screen generation unit 13 refers to the processing information, processing condition information, and facility information, and determines the material and dimensions of the cover A and the jigs required for drilling. The facility P1 is extracted as a candidate. When there is an equipment that satisfies the conditions other than the equipment P1, the input screen generating unit 13 displays the candidate equipment in a pull-down manner.

  In this way, the designer inputs the process information of all the parts that need processing on the input screen.

  Returning to FIG. 1, the input unit 16 of the parts table creation support apparatus 1 acquires process information input on the input screen by the designer. The input unit 16 sends the acquired process information to the manufacturing parts table generation unit 17.

  The process information may be input directly to the input unit 16 by the designer, or may be transmitted from the terminal used by the designer to the BOM creation support apparatus 1 and received by the input unit 16.

  The manufacturing parts table generation unit 17 generates manufacturing parts table information from the parts configuration information stored in the design parts table storage unit 12 and the process information received from the input unit 16 and stores the manufacturing parts table information in the manufacturing parts table storage unit 18. . The manufacturing parts table information is information indicating what processes are performed on which parts in what order in which equipment and how many man-hours to manufacture a product.

  FIG. 8 is a diagram illustrating an example of manufacturing parts table information according to the embodiment. The manufacturing parts table generation unit 17 generates manufacturing parts table information shown in FIG. 8 from the parts configuration information and process information.

  The manufacturing bill of material information includes a “level” indicating the part configuration of the product, a “name” indicating the name of the product or part, a “number” indicating the figure number of the product or part, and a “quantity” indicating the quantity of the product or part. It consists of “items” consisting of items and “processes” consisting of “inspection”, “assembly”, “mounting”, “painting”, “molding”, “drilling”, and “purchasing” indicating various processes. Is done.

  FIG. 8 shows manufacturing parts table information of the finished product A. “Level” ranges from 1 to 3, and level 1 indicates a product. Level 2 shows the parent part. Level 3 shows child parts.

  For example, the cover A, which is the parent part, uses the steel material B and the paint A as the child parts. Steel B and paint A are purchased. The cover A is completed using the steel material B and the paint A by performing 25 shots of drilling, 4 processes of forming, and 1 process of painting. The manufacturing parts table information includes attached information regarding each process performed on a product or a part. The attached information is associated with the name or figure number of the product or part.

  FIG. 9 is a diagram showing an example of attached information included in the manufactured parts table information according to the embodiment. FIG. 9 shows attached information of the cover A (drawing number abc222). For example, it is assumed that the designer selects “drilling” as the first process of the cover A, selects the equipment “P1”, and inputs the man-hour “25” on the process information input screen shown in FIG. It is assumed that “Molding” is selected as the second to fifth steps, the equipment “B1” is selected, and the man-hour “1” is input. It is assumed that “painting” is selected as the sixth step, equipment “D1” is selected, and man-hour “1” is input.

  The input unit 16 acquires the process information input by the designer on the input screen and sends it to the manufacturing parts table generation unit 17. The manufacturing parts table generation unit 17 generates the attached information shown in FIG. 9 from the process information received from the input unit 16, and associates it with the cover A (drawing number abc222) of the manufacturing parts table information shown in FIG. The attached information is generated in the same manner for products or parts that require other processing.

  Returning to FIG. 1, when the manufacturing parts table information is stored in the manufacturing parts notation unit 18, the output unit 19 of the parts table creation support apparatus 1 outputs the manufacturing parts table information. As the output method, manufacturing parts table information may be displayed on the screen, printed out as an instruction sheet, and made available for viewing by a worker or inspector, or used by a worker or inspector. The instruction information may be transmitted to the terminal. Further, the output unit 19 may accept input of a request from a worker or inspection person, and may output manufacturing parts table information when the request is input.

  The person in charge of the work or the person in charge of inspection looks at the manufacturing parts table information and schedules work or inspection.

  FIG. 10 is a flowchart illustrating an example of the operation of the parts table creation support process according to the embodiment. The parts table creation support process starts when the parts table creation support apparatus 1 is turned on.

  When the design parts table acquisition unit 11 of the parts table creation support apparatus 1 does not acquire the design parts table information (step S11; NO), the process repeats step S11 and waits for the acquisition of the design parts table information.

  When the design parts table information is acquired (step S11; YES), the design parts table acquisition unit 11 stores the part configuration information, the part information, and the processing information in the design parts table storage unit 12. When the component configuration information, the component information, and the processing information are stored in the design parts table storage unit 12, the input screen generation unit 13 uses these information and the processing condition information and facility information stored in the condition storage unit 14. A process information input screen is generated (step S12).

  The display unit 15 displays the input screen generated by the input screen generation unit 13 (step S13).

  When the input unit 16 does not acquire the process information input on the input screen (step S14; NO), the process repeats step S14 and waits for acquisition of process information. When the process information is acquired (step S14; YES), the input unit 16 sends the acquired process information to the manufacturing parts table generation unit 17.

And stored in the manufacturing parts table storage unit 18.

  When the manufacturing part table information is stored in the manufacturing part notation unit 18, the output unit 19 outputs the manufacturing part table information (step S16).

  If the power of the parts table creation support apparatus 1 is not OFF (step S17; NO), the process returns to step S11, and steps S11 to S17 are repeated. If the power is turned off (step S17; YES), the process is terminated.

  As described above, according to the parts table creation support apparatus 1 of the embodiment, the process parts list of the product having the machining process is supported by the designer, and the production parts list is created at the design stage. It is possible to advance the timing of parts arrangement and production start that require maintenance, and to reduce rework due to design defects. In addition, it can be expected to prevent the misuse of parts in the production stage due to the review of the manufacturing parts list that has occurred and the omission of review due to every design change.
