  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic configuration diagram of a sheet metal equipment product sales system 1 according to the present embodiment.

  The sheet metal equipment product sales system 1 includes a sheet metal equipment product (laser processing machine, NC turret punch press, bending machine, mold, software, jig, etc.) in its own factory and a user 3 who performs sheet metal processing. And a seller 5 who sells sheet metal equipment products to the user 3 based on an optimal proposal for sheet metal processing. The user 3 and the seller 5 can communicate with each other via a network (for example, a dedicated line, the Internet, etc.) 23.

  The user 3 includes an information terminal 7 for obtaining information on sheet metal equipment products and answers such as questions.

  The seller 5 performs a process of making the virtual processing and the proof processing the same, the call center 9 that answers the question of the user 3 and supports the entire sheet metal processing, the seller computer 11 provided in the seller 5, and the like. A sheet metal processing laboratory 17 to be performed, a demonstration factory 19 for performing actual processing of products and photographing, and a demonstration processing exhibition hall 21 for showing actual processing to the user 3 are provided.

  The proposer computer 11 includes an editing unit 13 and a sheet metal database (database) 15. Here, it is assumed that the proposer computer 11 is not only a single computer but also a computer system that is installed in a plurality of places and can perform network communication.

  The editing unit 13 edits product drawing related information (paper drawing, CAD data, 3D model, etc.), and generates product drawing related editing information such as a 3D model of the product, development view information, attribute information, and the like. Then, the same or similar product as the product related to the user is searched from the sheet metal database 15, the registered product production information associated with the same or similar product is read, the registered product production information, and the product drawing related editing information. The user product production information, which is information on an appropriate production method by an appropriate production facility for the product related to the user, is created. Further, when the user gives an instruction, the product related to the user is verified with actual equipment to create verification processing information.

  The sheet metal database 15 includes product drawings, product manufacturing processes, three-dimensional models, development views, sheet metal properties (scripts), processing methods, processing machine tools, know-how, procedures, verification data (quality, accuracy, time, etc.), verification Information (registered product production information) in which video images are associated with each other is stored.

  FIG. 2 shows a schematic flow of the sheet metal equipment product sales system 1. That is, the user 3 accesses the seller computer 11 from the information terminal 7 in order to purchase a sheet metal equipment product (for example, NC turret punch press, laser processing machine, bending machine, etc.). Then, product drawing related information, which is design data (such as a paper drawing of the product, a CAD drawing, a three-dimensional model) of the sheet metal product of its own is transmitted.

  The seller computer 11 receives the product drawing related information and edits it (for example, generates a three-dimensional model, development drawing information, attribute information, etc.). Subsequently, when proof processing is necessary (for example, when the user 3 wants to see the actual processing or when the same or similar product is not searched), processing data is created and proof processing is performed. The actual machining is performed at the center (including 19, 21, etc.). This proof processing is transmitted as proof processing data to the information terminal 7 included in the user 3 as proposal information. Then, the user 3 determines whether or not to purchase the sheet metal equipment product with reference to the proposal information.

  Please refer to FIG. The processing flow of each data in the user 3, the call center 9, and the sheet metal processing laboratory 17 is shown. Step S301 is a case where the user 3 sends a paper drawing (included in product drawing related information). Step S303 is a case where the drawing is transmitted as data based on DXF or the like (included in the product drawing related information). Step S305 is a case of transmitting a three-dimensional model (included in product drawing related information).

  In step S307, if the received drawing is a paper drawing, it is read as image data by a scanner or the like. The drawing is traced by CAD.

  In step S309, when the received data is data such as DXF, automatic conversion processing is performed on CAD drawing data.

  In step S311, a three-dimensional figure (three-dimensional model) is created by an operation according to the procedure. In step S313, a three-dimensional figure (three-dimensional model) is completed. In step S315, development view information is created. In step S317, the attribute information of the sheet metal product is extracted and stored in the sheet metal database (database) 15.

  In step S319, the stereoscopic figure (stereoscopic model) is edited, and the three-dimensional figure (stereoscopic model) of the product is divided and examined for processing (if there is a VA / VE proposal, editing related to the product drawing) Created as information).

  At this time, the same or similar product as the product related to the user 3 is searched from the sheet metal database (database) 15, and registered product production information associated with the same or similar product is read. Then, using the registered product production information and product drawing related editing information, user product production information which is information on an appropriate production method by an appropriate production facility for the product related to the user is created.

  In step S <b> 321, attribute information extracted from the product related to the user 3 (for example, shape characteristics such as bending length and forming process) is registered in the sheet metal database (database) 15.

  In step S323, when proof processing is necessary (for example, when the user 3 wants to see actual processing directly, when the same or similar product is not searched), processing data is created from the development view information. In step S325, production management is performed. In step S327, verification processing is performed and created as verification processing information.

  Subsequently, proposal information including user product production information and verification processing information is transmitted to the user 3.

  Please refer to FIG. The details of the proposal information created by the user product production information and the verification processing information are shown. That is, the seller (including the call center 9, demonstration factory 19, sheet metal processing laboratory 17, demonstration processing exhibition hall 21) 5 that has received the product drawing related information (paper drawing, CAD drawing, three-dimensional model, etc.) 401 is the user 3. As proposal information, CG model data 403, estimate data, product processing time (including delivery date, etc.) data 405, data generation method (NC data generation, bending processing feasibility determination, CAD operation etc. CG, video proposal) data 407, product processing method (processing machine operation method, processing know-how, processing machine operation etc. CG, moving picture proposal) 409, and increased profit verification result data 411 are created and transmitted. Thereby, the user 3 can speed up the purchase decision-making of the sheet metal equipment product.

  FIG. 5 shows the processing operation of the editing unit 13. That is, the editing unit 13 reads the received CAD data. In step S501, a three-dimensional view (three-dimensional model) of the product is created from the three-view data of the product stored in the editing unit 13.

  In step S503, the created three-dimensional figure (three-dimensional model) is divided into a three-dimensional figure (three-dimensional model) of the part in consideration of bending or the like. At this time, the editing unit 13 creates welding / assembly instruction data (for example, displays an assembly method using a three-dimensional model) and stores it in the memory.

  In step S505, the three-dimensional figure (three-dimensional model) of the parts divided in step S503 is displayed on the screen in the order of processing targets.

  In step S507, whether or not bending is possible is determined with reference to a three-dimensional figure (three-dimensional model) of the component displayed on the screen. Here, the editing unit 13 calculates the L value, which is the distance from the abutment to the bending tool position, and the D value, which is the descending position of the bending tool, for each bending process, and stores them in the memory. The L value and D value are calculated for each processing step.

  In step S509, a development view is created with reference to a three-dimensional view (three-dimensional model) of a part that is determined to be bendable by determining whether or not bending can be performed. The editing unit 13 creates NC data of the processing machine for cutting the developed part from the sheet metal sheet by referring to the development view (this makes it possible to virtually simulate the operation of the processing machine). The processes from step S505 to step S509 are performed for the number of divided parts. This completes a virtual simulation (included in the product drawing related editing information) that allows the product production method to be virtually recognized on the screen.

  FIG. 6 shows the operation of the estimation / delivery date calculation process. That is, the product drawing related information (for example, CAD data) is read by the editing unit 13 from the memory. In step S601, a three-dimensional view (three-dimensional model) of the product is created from the three-view CAD data of the product stored in the editing unit 13.

  In step S603, the created three-dimensional figure (three-dimensional model) is divided into a three-dimensional figure (three-dimensional model) of the part in consideration of bending and the like. At this time, the assembly time T601, the painting time T603, and the welding time T605 are calculated and stored in the memory. Further, referring to each time, etc., the assembling cost K601, the painting cost K603, and the welding cost K605 are calculated and stored in the memory.

  In step S605, the three-dimensional figure (three-dimensional model) of the parts divided in step S603 is displayed on the screen in the order of processing targets.

  In step S607, it is determined whether or not bending is possible with reference to a three-dimensional figure (three-dimensional model) of the component displayed on the screen. Here, the bending time T607 is calculated. Further, the bending cost K607 is calculated with reference to the processing time and the like.

  In step S609, a development view is created with reference to a three-dimensional view (three-dimensional model) of a part that is determined to be bendable by determining whether or not bending can be performed. By referring to this development view, a blanking time T609 is calculated. Then, blank processing cost K609 is calculated with reference to blank processing time, material cost, and the like. The processes from step S605 to step S609 are performed for the number of divided parts. Thereby, the delivery date calculation T611 can be performed. Further, the product cost K613 can be calculated with reference to the material cost K611. By combining these, a CG estimate is created. When there is a VE / VA proposal or the like during the simulation, text data is created and stored in the memory. Thereby, the user 3 can know in advance the time and cost of manufacturing the sheet metal product when purchasing the sheet metal equipment product.

  FIG. 7 shows the operation of the technical transfer process. Here, the seller 5 logs in to the information terminal 7 from the seller computer 11, and the seller 5 determines that the user 3 and the user 3 are based on the verification data and processing know-how of similar work from the sheet metal database (database) 15. It is assumed that a process editing meeting is held to determine a product production method while considering sheet metal processing. That is, the product drawing related information (for example, CAD data) is read by the editing unit 13 from the memory. In step S701, a three-dimensional figure (three-dimensional model) is created from the three views of the product stored in the editing unit 13. For example, the information terminal 7 is operated in accordance with an instruction from the user 3. As a result, it is possible to carry out technology transfer that combines knowledge possessed by a bending specialist and a CAD / CAM specialist.

  In step S703, the three-dimensional figure (three-dimensional model) of the created product is divided into three-dimensional figure (three-dimensional model) of the part in consideration of bending processing or the like. Again, the user 3 and the seller 5 work together.

  In step S705, the three-dimensional figure (three-dimensional model) of the parts divided in step S703 is displayed on the screen in the order of processing targets.

  In step S707, whether or not bending is possible is determined by software based on the sheet metal database 15 based on the three-dimensional figure (three-dimensional model) of the component displayed on the screen.

  In step S709, a development view is automatically created from a three-dimensional model of a part that is determined to be bendable based on whether or not bending is possible.

  The processes from step S705 to step S709 are performed for the number of divided parts.

  As a result, it is possible to make a product (work editing conference) on a computer before actual manufacturing and digitize and share the processing method. That is, the technologies possessed by the user 3 and the seller 5 can be integrated and accumulated.

  Please refer to FIG. The operation of creating proposal information (particularly increased profit) based on product drawing related information received from the user 3 is shown.

  In step S801, similar workpieces are searched from the sheet metal database (database) 15. When there is a similar work, the similar work is referred to and proposal information is created. Since this similar work may include demonstration processing actually processed by a predetermined processing facility in the past, the reliability of each accompanying processing information is high.

  On the other hand, when a similar workpiece is not found, the possessed equipment information is read from the customer database, and a three-dimensional figure (three-dimensional model) is created, parts are separated, whether bending is possible, and a development drawing is created. Then, it is possible to perform a faithful processing simulation for equipment owned by the customer or equipment proposed by the dealer (including new products). The sheet metal processing laboratory 17 and the demonstration factory 19 create a three-dimensional figure (three-dimensional model), determine whether parts are separated, determine whether or not to bend, develop a development drawing, and perform a demonstration process to examine the optimum machining method. This makes it possible to accurately propose a comparison between the processing at the existing equipment (referred to as the current equipment) and the processing at the proposed equipment.

  In step S803, the proposed equipment, mold, software, etc. are determined in the process of step S801 described above. Then, it is stored in the memory.

  In step S805, the product processing time by the proposed equipment is calculated.

  In step S807, the product processing time for the user 3's current equipment is calculated.

  In step S809, an increase profit proposal material is created by referring to (subtracting) the product processing time of the proposed equipment and the product processing time of the user 3's current equipment.

  In step S811, the editing unit 13 creates proposal information 813 and transmits the proposal information 813 to the information terminal 7.

  Please refer to FIG. The flow of demonstration processing is shown. In step S901, the editing unit 13 performs a product processing simulation.

  In step S903, verification processing is performed in accordance with the product processing simulation. In this case, the equipment to be processed may be already delivered equipment owned by the user or proposed equipment suggested by the dealer. This demonstration processing is performed in the demonstration processing center 301 described above. This demonstration processing is photographed as an actual processing image and stored in a memory.

  In step S905, it is determined whether the result of the product processing simulation matches the result of the demonstration processing. When it is determined that they match, the process proceeds to step S907. When it is determined that they do not match, the process proceeds to step S909.

  In step S907, proposal information is created and a virtual proposal is made.

  In step S909, the proposal information is corrected with the real result based on the demonstration machining actually machined in the demonstration machining center 301. Thereby, the result of processing can be proved completely.

  In step S911, a virtual correction proposal is made. Thereby, the user 3 can trust the result of a process.

  In step S913, the cause analysis of the mismatch between the virtual and the demonstration processing is performed. By accumulating the cause of this discrepancy and reflecting it in the machining simulation, it is possible to create reliable proposal information in a virtual product machining simulation without performing demonstration machining. In particular, if demonstration processing is performed with a proposed facility (new product, etc.) proposed by a dealer, it is proved that processing with higher profit can be realized.

  The data stored in the above includes the following. In other words, the standard master (Product Variety Standard, Process Design Standard, Assembly Design Standard, Welding Standard, Bending / Mold Standard, Bending Interference Standard, Laser Cutting Condition Standard, Punching / Mold Allocation Standard, Machining Accuracy Standard And quality standards such as scratches) and calculation parameters (processing time / setup time for each machine, material handling / conveying time, processing time / setup time for human processes, elongation value for each material type / bending mold, etc.) is there.

  FIG. 10 shows an example in which the product processing simulation shown in FIG. 9 matches the actual processing. That is, although there was a concern about the interference between the mold and the part due to the D value considering the spring back due to the material, it was determined that the product was not affected as a result of the demonstration processing. By reflecting and accumulating this result in the sheet metal database 15, as a result, when the virtual part 1005 is bent by the virtual punch mold 1001 by simulation and the virtual die mold 1003, the virtual end of the virtual part 1005 is the virtual punch mold. It can be determined that it interferes with 1001 but does not affect the product.

  Although the outline of the sheet metal equipment product sales system 1 has been described above, a more detailed description will be given below. In addition, as described above, management / creation of product drawing related information, product drawing related editing information, registered product production information, etc. can be performed by being distributed to the computer devices provided in the call center 9, the sheet metal processing laboratory 17, etc. In the following description, it is assumed that the editing unit 13 included in the seller computer 11 performs the respective processes in a concentrated manner via a network.

  That is, as shown in FIG. 11, the editing unit 13 includes a process editing unit 31, a search unit 33, a user product production information creation unit 35, a verification unit 37, a proposal information creation unit 43, and a communication unit 45. I have.

  The process editing means 31 performs various editing processes for processing products. The search means 33 performs a process of searching for a product that is the same as or similar to the product. The demonstration means 37 performs actual processing on the product and obtains various information therefrom. The proposal information creating means 43 creates information for proposing to the user. The communication means 45 transmits and receives various information.

  The verification means 37 includes table management means 39 for managing each table, and verification processing information creation means 41 for performing verification processing and creating predetermined information.

  Please refer to FIG. The overall operation of the sheet metal equipment product sales system 1 is shown. In step S1201, the user 3 is prompted to access the seller computer 11 from the information terminal 7 of the user 3. In step S <b> 1203, the editing unit 13 provided in the seller computer 11 receives the product drawing related information of the product and stores it in the memory 25 of the seller computer 11.

  In step S1205, the search means 33 searches and reads registered product production information associated with the same or similar product from the sheet metal database (database) 15. Subsequently, it is stored in the memory 25.

  In step S1207, the search unit 33 determines whether to use the search result as it is. If it is determined that the search result is to be used as it is, the process proceeds to step S1213. If it is determined that the search result is not used as it is, the process proceeds to step S1209.

  In step S1209, the process editing unit 31 generates / edits product drawing related editing information. In step S <b> 1211, the process editing unit 31 creates and edits user product production information (proposed equipment / suggested process or existing equipment / suggested process) and stores it in the memory 25.

  In step S1213, the verification means 37 determines whether verification processing is necessary. When it is determined that demonstration processing is necessary, the process proceeds to step S1215. When it is determined that the demonstration process is not necessary, the process proceeds to step S1217. Note that the case where demonstration processing is necessary is, for example, when the user 3 transmits instruction data indicating that demonstration processing is to be performed.

  In step S <b> 1215, the proof machining information creation unit 41 creates proof machining information and stores it in the memory 25. In step S1217, the user product production information creation means 35 refers to the customer database (owned equipment information) 27 to create / edit user product production information (proposed equipment / suggested processing or existing equipment / suggested processing) and store it in the memory 25. To do.

  In step S <b> 1219, the communication unit 45 distributes the proposal information created by the proposal information creation unit 43 (user product production information, demonstration processing information, or both information) to the user 3.

  Also, for example, first, when there is an instruction from the user 3, verification processing information (information obtained by actual processing) is created by performing verification processing of the product related to the user 3 at the production facility of the user 3. The proposal information for comparing and proposing the difference with the user product production information (information created by virtual trial production) by the proposal facility of the seller 5 can be distributed. Further, the difference between the virtual production information by the existing equipment of the user 3 and the actual processing information by the proposed equipment proposed by the seller 5, or the difference in each case of the real or virtual processing information in both equipments is confirmed.

Is stored in the sheet metal database 15. Specifically, as shown in FIG. 20C, conditions: material / plate thickness / V width / bending angle / bending type are set for rough skin. Then, a reference level for a product that meets this condition is set.

  The quality verification procedure is shown below. Based on the user product production information, a part (checkpoint) that matches the condition of each quality item is extracted, and the reference level (virtual trial production level by simulation) of the part is identified with reference to the condition. The quality check table TH shown in FIG. 20 (d) manages the extracted information.
