Next, the operation of the equipment design / evaluation apparatus 30 will be described with reference to the flowchart shown in FIG.
In step 1, product design data produced by the equipment to be designed is extracted from the common database.

In step 2, the designer inputs the production condition data using the input device 70. When inputting the production condition data, a screen as shown in FIG. 11 is displayed on the display device, and the production conditions such as the planned production amount of the product, the number of models and the product life such as how many years the product is produced are displayed. input. Further, here, a fuzzy membership function pattern corresponding to each production condition data is selected from the displayed plurality of membership function patterns, and values such as height and slope of the function pattern are input. If the value of the function pattern is a standard value, it is not necessary to input it, and only when it is necessary to change it. Thus, choosing a membership function will eventually
At the stage of outputting the manufacturing facility design result, for example, with respect to the planned production amount, the percentage of which the appropriate production method is suitable is output from the suitability of the selected membership function. In addition, for example, when the planned production volume is not specifically determined, by inputting a value that has a range in the production volume to some extent, the fitness of the selected membership function is used, and a rough facility design is performed. Is done.

In step 3, the manufacturing easiness is evaluated using the product design data and the production condition data.
At this point, if the manufacturability does not reach the target (step 4), the product design is improved (step 5). If manufacturability meets the goal (step 4),
In step 6, the designer inputs the line construction policy using the input device 70. When inputting the line construction policy, the input screen as shown in FIG. 12 is displayed, and a necessary item is selected from the displayed plurality of items, for example, “automation” and “lead time reduction” are marked. Enter the specific target value of each selected item, and also enter the degree of priority of that item over other items in%. Further, if there is a detail that cannot be represented only by this table, mark the detail column and enter the details separately.

In step 7, the designer uses the input device 70 to input the constraint conditions. When inputting a constraint condition, an input screen as shown in FIG. 13 is displayed, and a necessary item is selected from the displayed items, for example, “floor area” and “return on investment capital” are marked. Select and add specific condition values for each selected item, and input the degree of importance for this condition in%. In addition, 100% of importance means an absolute requirement here. Furthermore, if there are detailed conditions, mark the details column and enter the details separately.

In step 8, the equipment design / evaluation apparatus 30
The general overall design unit 31 of executes the general overall design of the equipment. In the general overall design, out of the product design data, a general process design is performed from the size of parts, assembly operation, processing operation, assembly order, etc. The data related to the price of the virtual device corresponding to this specification is called. Step 9
Then, the simulation apparatus 40 builds an equipment model from the schematic process design result obtained in step 8 and executes the simulation. In this simulation, a physical distribution simulation for confirming where and how many parts are accumulated during manufacturing, and an operation rate simulation for confirming operation contents of each device and a person are performed.

In step 10, the general overall designing section 31
However, it outputs the number of stations, the approximate number of devices used, the approximate automation rate, the approximate number of required workers, the approximate capital investment amount, etc. The number of stations, the approximate number of devices to be used, and the approximate capital investment amount are determined at the stage of the rough process design in step 8. As for the rough automation rate, as shown in FIG. 22, from the number of parts and the ease of assembly evaluation point or the workability evaluation point of each part, the automation rate setting rule according to the evaluation point as shown in FIG. On the basis of,
Find the process that can be automated and the automation rate. Regarding the required number of workers, use the work time calculated from the manufacturability evaluation method and the automatable process (or parts) obtained when the automation ratio was calculated, as shown in the figure. According to the rules. In step 11, the designer looks at the output contents of step 10 and judges whether or not each meets the goal. If they match the goal, the designer proceeds to the next step (step 12) If not, the product design CAD device 10 is used to change the product design (step 5).

By the way, the loop up to this point is executed when the product is designed or improved. Therefore,
Generally, the product designer inputs the product design data by himself, so the product designer inputs the information such as the production condition data, the line construction policy and the constraint condition with a very small amount of input data. Although it is an outline, you can know about manufacturing equipment. For this reason, the product designer can design the product in consideration of the manufacturing facility without being overloaded.

In step 12, the equipment design / evaluation device 3
The 0 process design unit 32 executes a specific process design.
Note that the subsequent processing will be mainly handled by the production engineer or equipment designer. There are assembly process and processing process in the process of manufacturing equipment, but in the process design here, there is no big difference in the process design procedure for both, so here, the process design procedure is explained using the assembly process as an example. To do.

In the assembling process design, first, as shown in FIG. 15, the assembling order used in the assembling performance evaluation, that is, in FIG.
It is decided to be 3,2,1 according to 2,1, and the action basic element (action analysis symbol) is set corresponding to each part A, B, C,
Create a basic model. Next, as shown in FIG. 16, parts may not flow smoothly in the basic model, so an intermediate model obtained by leveling the basic model is created. Further, the quantity of this intermediate model is determined and an intermediate modified model is created. In determining the quantity of the intermediate model, first, the target production time in the production condition data, the working time per day (number of shifts), and the target tact time for producing one product from the number of moving days per month. Calculate T. Then, when one step of the intermediate model exceeds the target takt time T, the number of intermediate models is increased.

Next, as shown in FIGS. 17 and 21,
Based on the operation of the basic elements written under each process and the correction factors such as the size of parts set at the time of the manufacturability evaluation, the specifications such as the operation and ability of the device are determined, and the common database Extract the appropriate commercial device from 70 and fit it into the interim modified model. At this time, the application of the existing equipment will also be examined so that the existing equipment can flow. Specifically, as shown in FIG. 26, an appropriate existing device registered as a constraint condition in the common database 70 is extracted, and a new commercially available device for the determined specifications is extracted. Existing equipment, the existing equipment shall be used if the equipment meets the capacity of the new commercial equipment. (2) If the equipment of the new commercial equipment meets the capacity of the new equipment by adding auxiliary equipment to the existing equipment, Set rules such as the use of equipment and so that the flow rate of existing equipment can be used as much as possible. When there is no corresponding commercially available device in the common database 70 at the time of extracting the commercially available equipment, it is assumed that there is a device with the determined specifications and the subsequent processing is executed.

The assembly process thus determined is sent to the simulation device 40. The simulation device 40 converts the sent assembly process data into data that can be simulated, and then executes a physical distribution / operation rate simulation. Then, based on this result, as shown in FIG. 18, the buffer capacity between each process of the line,
The operating rate of each device, the distance between processes, etc. are determined. If the device and the process are specifically determined, the automation rate and the required number of workers can be obtained almost accurately. Therefore, the automation rate and the required number of workers are calculated again here. As shown in FIG. 24, the required number of workers is calculated from the assembling or machining ease score of the component and the determined device.

In step 13, the machining / assembly station designing unit 33 executes the design of the machining / assembly station. Here, the specifications of the station are determined based on the process design determined in step 12. Specifically, the type and number of devices used in the station are determined. In step 14, the product transportation design unit 34 determines a transportation method and a transportation device for parts / products. Here, as shown in FIG. 19, the product transfer device to be used is determined in accordance with the processing rule as shown in the figure from the production amount, the size of the product, the accuracy, the workability evaluation point, and the like. In the example of the figure, only the rule when the free flow conveyor is selected is shown, similarly, the rule when the fixed cycle conveyor is selected, the rule when performing work on the continuous moving conveyor, the conveyor The rules for selecting a machining center or an assembly center system in which machining / assembling equipment approaches a product without using are also set in advance.

In step 15, the parts supply design unit 35
However, as shown in FIG. 20, the component supply system for the device such as bulk supply, magazine supply, kit distribution, etc. is determined from the size of the component, the assembly posture of the component, the component accuracy, etc., and this is output.

In step 16, the parts stock designing section 3
6 determines the warehouse capacity, the size of the lot to be taken out from the warehouse, and the like, based on the production volume and the component supply system determined in step 15. In step 17, the layout designing section 37 arranges the manufacturing equipment, the transportation equipment, the warehouse, etc. according to the process so as to fit within the “usable floor area” input as the constraint condition, and determines the layout of the equipment. In addition,
At this time, as shown in FIG. 25, for the specific device determined in step 12, etc., from the required floor area registered in the common database 70, according to a rule considering the margin ratio as shown in FIG. , Find the floor space required as a whole.

In step 18, the investment effect evaluation unit 38
However, the required investment amount, profit rate, and the number of months for collecting funds are calculated. As shown in FIG. 27, the investment amount is calculated based on the price data of each device and the correction coefficient a ₁ and the correction constant a ₂ in consideration of the installation work and the incidental work of the device. In step 19, it is judged whether or not the number of workers calculated in step 12 and the investment amount calculated in step 18 meet the target. If they do not match, the constraint condition or the target value is corrected. If it does not match, the process returns to step 5 again to improve the product. If it matches the target value, a large number of data obtained in steps 12 to 18 are output.

Here, a concrete output example will be described with reference to FIGS. 28 to 31. FIG. 28 shows an output example of a device used for each station. If an A3010 model of a horizontal articulated robot is used for the eighth station and a magazine and a magazine feeder are used for supplying parts, It's good. Further, below that, the reason why the robot is selected as a comment and the improvement points for further reducing the investment amount are output. This comment is automatically given depending on which rule was used when selecting the equipment, and the rule that met the conditions was the reason why the rule was selected and the rule that did not meet the conditions. The part that does not meet the condition of is shown as an improvement point. FIG. 29 shows an output example in the case where the number of assembling devices cannot be limited to one due to insufficient input conditions, and shows a plurality of possible devices and the percentage of the possibility. In addition, in the comment field,
It also outputs what kind of conditions the required device can be specified. FIG. 30 also shows an example of outputting the selected device. In this case, the device cannot be determined because the input condition is insufficient, and the comment field prompts the user to input the insufficient data. FIG. 31 is an output example of the layout design, and displays the layout of each work station, automated guided vehicle, warehouse, office, and the like. Although these outputs may be finally output at once in this way, they may be sequentially output when the output contents are determined, and the contents may be sequentially changed.

In step 20, CAD for auxiliary equipment design
The device 60 is used to design a device that has not been finally determined, and a necessary additional device.

As described above, in this embodiment, since the product designing to the equipment designing are performed by using one common data base 70, the data re-insertion and the data conversion work at each stage are performed one by one. There is no need to perform this, and the handling of data at each design stage can be simplified. In addition, since the manufacturing equipment can be planned immediately when the product design is completed or when the product design proposal is made, the development of the manufacturing equipment and the product development can be performed at the same time, and from the product design to the design of the manufacturing equipment. The time to finish can be shortened. This can be said to be very effective in recent years when the shipping cycle of new products has become shorter. In addition, when the product designer makes a design plan, he / she can know the outline shape of the manufacturing equipment and the amount of investment, so that feedback to the product design improvement is possible. Also, the production conditions and policies are
Since it can be input as a fuzzy function fit,
The facility plan can be executed even if the future production quantity plan is not clear. Also, if the input conditions are insufficient or if it is not possible to limit to one facility, the reason etc. will be output as a comment. Therefore, by referring to this comment, it is easy to improve the facility plan. It is possible to perform accurate equipment planning. In addition, various equipment planning know-how is stored as a processing rule, and since it is also evaluated by simulation, it is necessary to formulate an excellent plan even if there is no expert required for equipment planning in the past. You can
