[0010] FIG. 1 shows an example of a factory system 1 according to this embodiment.

[0011] The factory system 1 includes a processing machine 10 that processes materials, an information management unit 20 that controls the processing machine 10, and a virtual factory 30 that is connected to the processing machine 10 via the information management unit 20. The virtual factory 30 is connected to a terminal 50 via a line 40 such as the Internet.

[0012] The processing machine 10 may be a machine tool 10a, a heat treatment device 10b, a 3D printer 10c, or the like, which processes materials such as metal or resin by cutting, grinding, laser processing, electric discharge processing, etc. Each of the processing machines 10 can be controlled independently.

[0013] The processing machine 10 is installed in a production factory 2. The production factory 2 may be divided into multiple factories. The production factory 2 may have multiple processing machines 10. For example, in this embodiment, a first production factory 2a is equipped with a machine tool 10a and a heat treatment device 10b, and a second production factory 2b is equipped with a 3D printer 10c. Furthermore, the production factory 2 may be equipped with multiple processing machines 10 of the same type.

[0014] The information management unit 20 can comprehensively control the production factory 2 based on information transmitted from the multiple processing machines 10. The information management unit 20 can also calculate CAM data based on information transmitted from the virtual factory 30 and transmit the CAM data to the virtual factory 30.

[0015] By sharing information using the information management unit 20, the virtual factory 30 can reflect the status of the production factory 2 in real time and perform simulations. A user inputs parameters from a terminal 50, such as a smartphone 51, tablet 52, or PC 53, and transmits them to the virtual factory 30 via a line 40. The virtual factory 30 then transmits the received parameters to the information management unit 20.

[0016] The information management unit 20 uses the received parameters to create CAM data that reflects the situation of the production factory 2 in real time, and transmits the data to the virtual factory 30. The virtual factory 30 calculates delivery dates, costs, etc. from the CAM data that reflects the situation of the production factory 2 in real time.

[0017] When a user requests the production of an actual product, the virtual factory 30 instructs the information management unit 20 to carry out actual production using the processing machine 10. The information management unit 20 controls the production factory 2 based on the parameters input by the user, thereby causing actual processing to be carried out.

[0018] FIG. 2 shows a part of the production factory 2 of the factory system 1 of this embodiment.

[0019] The processing machine 10 has a drive unit 11 that drives various mechanisms equipped with tools, a drive status detection unit 12 that detects the operating status of the drive unit 11, an input / output device 13 such as an operation unit where the user gives instructions and a display unit that displays various information, a memory 14 that stores programs and parameters in advance and newly stores information such as processing results after processing, a CPU 15 that controls the drive unit 11 according to instructions from the input / output device 13 or programs stored in the memory 14 and sends information such as processing results to an information management unit 20, and an interface 16 that connects to the information management unit 20 via an in-house network. The production factory 2 has a transport unit 17 that transports materials to and from each processing machine 10, and a transport status detection unit 18 that detects the transport status of the transport unit 17.

[0020] The drive unit 11 is a servo motor, ball screw, linear motor, etc., and includes a power that imparts motion to the material or tool, and a guide mechanism that converts the power into a specific motion. The operating status detection unit 12 detects the operating status of the processing machine 10. The operating status may be the actual production volume relative to the production capacity of the processing machine 10, or the presence or absence of a malfunction of the processing machine 10, etc.

[0021] The input / output device 13 includes a touch panel or keyboard as an input unit for inputting various information such as a target operating rate, and includes a display as an output unit for displaying various information such as the operating status. The memory 14 stores in advance a program for controlling the operation of the drive unit 11 and various parameters of the processing machine 10. The memory 14 also stores the operating status of the drive unit 11.

[0022] The CPU 15 controls the drive unit 11 based on information from the operation status detection unit 12, the input / output device 13, and the memory 14. The CPU 15 is connected to the information management unit 20 via an interface 16.

[0023] The conveying unit 17 conveys the material to be processed to each processing machine 10. The conveying unit 17 may be installed between the processing machines 10, or may be installed across multiple processing machines 10. For example, multiple conveying units 17 may be installed between each processing machine 10, or one conveying unit 17 may be installed across multiple processing machines 10.

[0024] The conveyance status detection unit 18 detects the number of materials present in the conveyance unit 17, etc. Information on the conveyance status, etc. detected by the conveyance status detection unit 18 is transmitted to the CPU 15 or information management unit 20 of the processing machine 10 adjacent to the position of the detected conveyance unit 17.

[0025] The processing machine 10 can operate independently by having the CPU 15 control the drive unit 11 in accordance with the operating status detected by the operating status detection unit 12, instructions input from the input / output device 13, a program that controls the operation of the drive unit 11 in advance and that is stored in the memory 14, and various parameters of the processing machine 10.

[0026] FIG. 3 shows the information management unit 20 of the factory system 1 of this embodiment.

[0027] The information management unit 20 controls the entire production factory 2 and manages information with the virtual factory 30. The information management unit 20 includes a parameter acquisition unit 21 that acquires parameters transmitted from the processing machines 10 or the virtual factory 30, a processing machine specification acquisition unit 22 that acquires specifications of the processing machines 10 installed in the production factory 2, a production factory status detection unit 23 that detects the overall status of the production factory 2, a CAM data creation unit 24 that creates CAM data for controlling the drive units 11 and conveyance units 17 of each processing machine 10, a factory control unit 25 that controls the production factory 2 based on the CAM data created by the CAM data creation unit 24, and a simulation result storage unit 26 that stores the results of a simulation performed in the virtual factory 30.

[0028] The parameter acquisition unit 21 acquires parameters transmitted from the processing machine 10 or the virtual factory 30. The parameters transmitted from the processing machine 10 are parameters input by the user from the processing machine 10, and the parameters transmitted from the virtual factory 30 are parameters input by the user from the terminal 50.

[0029] The processing machine specification acquisition unit 22 acquires specifications stored in the memory 14 of the processing machine 10 installed in the production factory 2. The production factory status detection unit 23 detects the overall status of the production factory 2 by compiling information sent to the CPU 15 from each operation status detection unit 12 and each transport status detection unit 18. The CAM data creation unit 24 creates CAM data based on the parameters entered by the user acquired by the parameter acquisition unit 21, the specifications of the processing machine 10 acquired by the processing machine specification acquisition unit 22, and the status of the production factory 2 detected by the production factory status detection unit 23. The factory control unit 25 controls the drive unit 11 and transport unit 17 of each processing machine 10 in the production factory 2 based on the CAM data created by the CAM data creation unit 24.

[0030] For example, when the first conveyance status detection unit 18 detects that a large amount of material is present in front of the first processing machine 10 in the production factory 2, the first conveyance status detection unit 18 transmits the conveyance status to the information management unit 20. The information management unit 20 transmits control content to the CPU 15 of each processing machine 10 to improve efficiency, and the CPU 15 of each processing machine 10 controls a predetermined drive unit 11. The information management unit 20 may also control the conveyance unit 17.

[0031] The simulation result storage unit 26 stores information simulated in the virtual factory 30. The information simulated in the virtual factory 30 includes information input from the terminal 50, the settings of the processing machine 10 and the transport unit 17 simulated in the virtual factory 30, delivery dates and costs calculated in the virtual factory 30, etc.

[0032] 4 shows the virtual factory 30 of the factory system 1 of this embodiment. The virtual factory 30 reflects in real time the operating status of the production factory 2. In other words, the production factory 2 and the virtual factory 30 have a digital twin relationship.

[0033] The virtual factory 30 has a parameter receiving / transmitting unit 31 that receives parameters input from the terminal 50 and transmits them to the information management unit 20, a CAM data acquisition unit 32 that acquires CAM data created by the CAM data creation unit 24 of the information management unit 20, a delivery date cost calculation unit 33 that calculates delivery dates and costs from the CAM data acquired by the CAM data acquisition unit 32, a simulation result creation unit 34 that summarizes the simulated results, and a production instruction unit 35 that transmits production instructions to the information management unit 20 when production at the production factory 2 is instructed from the terminal 50.

[0034] The parameter receiving / transmitting unit 31 receives parameters input by the user from the terminal 50. The parameters may be information such as material, dimensions, weight, shape, quantity, etc., and may be information necessary for processing the product. The CAM data acquiring unit 32 acquires CAM data created by the CAM data creating unit 24 of the information managing unit 20. The CAM data includes a processing program, etc.

[0035] The delivery time cost calculation unit 33 calculates the delivery time and cost required to manufacture the product from the data acquired by the CAM data acquisition unit 32. The delivery time and cost may be calculated in consideration of the factory situation in real time, or may be calculated regardless of the factory situation. The simulation result transmission unit 34 compiles the simulation results and transmits them to the simulation result storage unit 26 of the information management unit 20 and the terminal 50. The simulation results include at least one of the input parameters, CAM data, delivery time, cost, etc.

[0036] When an instruction to produce a product at the production factory 2 is received from the terminal 50, the production instruction unit 35 instructs the information management unit 20 to produce the product. The product is produced at the production factory 2 based on the simulation results stored in the simulation result storage unit 26.

[0037] 5 shows a first example of the control flow of the factory system 1 of this embodiment. In the first example shown in FIG. 5, the information management unit 20 controls the production factory 2 based on input from the processing machine 10.

[0038] In step 11, the parameter acquisition unit 21 of the information management unit 20 determines whether or not the parameters input from the input / output device 13 of the processing machine 10 have been acquired (ST11). If the parameter acquisition unit 21 has not acquired the parameters in step 11, the process returns to step 11.

[0039] If the parameter acquisition unit 21 acquires the parameters in step 11, then in step 12 the processing machine specification acquisition unit 22 of the information management unit 20 acquires the specifications of the processing machine 10 (ST12).

[0040] Next, in step 13, the production factory status detection unit 23 of the information management unit 20 compiles the information sent to the CPU 15 from each operation status detection unit 12 and each conveyance status detection unit 18 of each processing machine 10 to detect the overall status of the production factory 2 (ST13).

[0041] Subsequently, in step 14, the CAM data creation unit 24 of the information management unit 20 creates CAM data for controlling the drive unit 11, the transport unit 17, etc. of each processing machine 10 (ST14).

[0042] Next, in step 15, the factory control unit 25 of the information management unit 20 controls the production factory 2 based on the CAM data created by the CAM data creation unit 24 in step 14 (ST15). Specifically, it controls the drive unit 12 and the conveyance unit 17 of the processing machine 10 in the production factory 2, and actually produces the product.

[0043] In this way, the information management unit 20 controls the production factory 2 while detecting the operating status of the production factory 2 in real time, so that the production status of the production factory can be grasped with high accuracy, and products can be produced efficiently.

[0044] Figure 6 shows a second example of the control flow of the factory system 1 of this embodiment. In the second example shown in Figure 6, the operating status of the production factory 2 is detected in real time based on input from the terminal 50, and a simulation is performed in the virtual factory 30. Furthermore, if instructed, the information management unit 20 controls the production factory 2 based on the simulation to produce products. The production factory 2 is linked to the cyber factory 30 as a sharing factory that can be used by multiple users.

[0045] First, in step 21, it is determined whether or not the parameter receiving / transmitting unit 31 of the virtual factory 30 has received parameters from the terminal 50 (ST21). If the parameter receiving / transmitting unit 31 has not acquired parameters in step 21, the process returns to step 21.

[0046] If the parameter receiving / transmitting unit 31 has acquired the parameters in step 21, then in step 22 the parameter acquiring unit 21 of the information managing unit 20 acquires the parameters from the parameter receiving / transmitting unit 31 (ST22).

[0047] Next, in step 23, the processing machine specification acquisition unit 22 of the information management unit 20 acquires the specifications of the processing machine 10 (ST23).

[0048] Next, in step 24, the production factory status detection unit 23 of the information management unit 20 compiles the information sent to the CPU 15 from each operation status detection unit 12 and each conveyance status detection unit 18 of each processing machine 10 to detect the overall status of the production factory 2 (ST24).

[0049] Subsequently, in step 25, the CAM data creation unit 24 of the information management unit 20 creates CAM data for controlling the drive unit 11, the transport unit 17, etc. of each processing machine 10 (ST25).

[0050] Next, in step 26, the CAM data acquisition unit 32 of the virtual factory 30 acquires the CAM data created by the CAM data creation unit 24 in step 25 (ST26).

[0051] Subsequently, in step 27, the delivery time and cost calculation unit 33 of the virtual factory 30 calculates the delivery time and cost from the CAM data acquired by the CAM data acquisition unit 32 (ST27).

[0052] Next, in step 28, the simulation result transmission unit 34 of the virtual factory 30 outputs the simulation results to the terminal 50 and the information management unit 20 (ST28).

[0053] Next, in step 29, the simulation result storage unit 26 of the information management unit 20 stores the simulation results transmitted from the simulation result transmission unit 34 (ST29).

[0054] Next, in step 30, it is determined whether or not a production instruction for the product has been sent from the terminal 50 to the production instruction unit 35 of the virtual factory 30 (ST30). If a production instruction for the product has not been sent from the terminal 50 to the production instruction unit 35 of the virtual factory 30 in step 30, the control ends.

[0055] In step 30, when a production instruction for a product is sent from the terminal 50 to the production instruction unit 35 of the virtual factory 30, in step 31, the factory control unit 25 of the information management unit 20 controls the production factory 2 based on the simulation results stored in the simulation result storage unit 26, and actually produces the product (ST31). Specifically, it controls the drive unit 12 and conveyance unit 17 of the processing machine 10 in the production factory 2, etc.

[0056] In this way, the factory system 1 can easily simulate the virtual factory 30 by inputting data from the terminal 50. Furthermore, the factory system 1 detects the operating status of the production factory 2 in real time, so it can accurately grasp the production status of the production factory and accurately indicate delivery dates and costs. Furthermore, if a user gives instructions from the terminal 50, the information management unit 20 controls the production factory 2 based on the simulation results, enabling efficient product production.

[0057] As described above, the factory system 1 of this embodiment is a factory system 1 that processes materials to create products, and includes a processing machine 10 having an input / output device 13 for inputting parameters, a drive unit 11 that processes the material, and an operation status detection unit 12 that detects the operation status of the drive unit 11, a transport unit 17 that transports materials to the processing machine 10, a transport status detection unit 18 that detects the transport status of the transport unit 17, and an information management unit 20 that controls the drive unit 11 and the transport unit 17, and the information management unit 20 includes a parameter acquisition unit 21 that acquires parameters input to the processing machine 10, and a processing status detection unit 12 that detects the operation status of the transport unit 17. The system includes a processing machine specification acquisition unit 22 that acquires the specifications of the machine 10, a production factory status detection unit 23 that detects the status of the production factory 2 from the operation status detection unit 12 and the transport status detection unit 18, a CAM data creation unit 24 that creates CAM data for controlling the drive unit 11 and the transport unit 17 based on the parameters acquired by the parameter acquisition unit 21, the specifications acquired by the processing machine specification acquisition unit 22, and the status of the production factory detected by the production factory status detection unit 23, and a factory control unit 25 that controls the drive unit 11 and the transport unit 17 based on the CAM data created by the CAM data creation unit 24.

Therefore, the production status of the production factory 2 can be grasped and a simulation can be performed with high accuracy in the virtual factory 30.

[0059] Furthermore, according to the factory system 1 of this embodiment, the virtual factory 30 has a production instruction unit 35 that transmits production instructions to the information management unit 20 when an instruction to produce at the production factory 2 is received from the terminal 50, and when the information management unit 20 receives an instruction from the production instruction unit 35, it controls the drive unit 11 and the transport unit 17 based on the CAM data stored in the simulation result storage unit 26. Therefore, when there is an instruction from the user via the terminal 50, the information management unit 20 controls the production factory 2 based on the simulation results, enabling efficient product production.
