[0010] Hereinafter, the present embodiment will be described with reference to the drawings. The present embodiment includes a tensile tester 1 according to a first embodiment, which will be described with reference to Figs. 1 to 6, and a particle analyzer 6 according to a second embodiment, which will be described with reference to Figs. 7 to 10.

[0011] [1. First embodiment] [1-1. Configuration of tensile testing machine] FIG. 1 is a diagram showing an example of the configuration of a tensile tester 1 according to the first embodiment. The tensile tester 1 of the first embodiment applies a test force F to a test piece TP to perform a tensile test to measure mechanical properties such as the tensile strength, yield point, elongation, and reduction of area of ​​the sample. The test force F is a tensile force. The tensile tester 1 includes a tester body 2 that applies a test force F to a test piece TP, which is a material to be tested, to perform a tensile test, and a control unit 3 that controls the tensile test operation performed by the tester body 2. The tensile tester 1 corresponds to an example of a "material testing machine".

[0012] As shown in FIG. 1, the testing machine body 2 is configured by forming a load frame on a base 26 with a pair of support columns 28, 29 and a yoke 13, and by fixing a crosshead 10 to the support columns 28, 29.

[0013] A hydraulic actuator 18 is disposed on the base 26, and a lower grip 22 for gripping the lower end of the test piece TP is attached to a piston rod 181 of the hydraulic actuator 18. In addition, an upper grip 21 for gripping the upper end of the test piece TP is attached to the crosshead 10 via a load cell 14.

[0014] The hydraulic actuator 18 extends and retracts a piston rod 181 by controlling the direction and amount of pressure oil by a servo valve 20. As a result, the distance between the upper grip 21 and the lower grip 22 extends and retracts, and a test force F is applied to the test piece TP fixed between the upper grip 21 and the lower grip 22. The stroke of the hydraulic actuator 18, i.e., the displacement of the test piece TP, is detected by a differential transformer 19 attached to the hydraulic actuator 18.

[0015] The load cell 14 is a sensor that measures a test force F, which is a tensile load applied to the test piece TP, and outputs a test force measurement signal SG1 to the control unit 3. The differential transformer 19 is a sensor that measures the amount of displacement of the test piece TP and outputs to the control unit 3 a displacement measurement signal SG2 corresponding to the amount of displacement.

[0016] A displacement sensor 15 is disposed on the test piece TP. For example, a dumbbell-shaped test piece formed with a constriction in the center is used as the test piece TP. The displacement sensor 15 is a sensor that measures an elongation measurement value ED by measuring the distance between a pair of reference points on the test piece TP, and outputs an elongation measurement signal SG3 to the control unit 3. The pair of reference points are disposed above and below the constriction area of ​​the test piece TP.

[0017] The testing machine main body 2 further includes an electric power source GE and a hydraulic power source GP. The power source GE supplies power to each part of the testing machine main body 2. The power source GE supplies power to, for example, various motors to drive them. The power source GE also supplies power to a hydraulic pump and a hydraulic control valve (not shown) to drive them. The power source GE is configured as, for example, a voltage source. The power source GE supplies the corresponding voltage to each part of the testing machine main body 2. For example, the power source GE supplies a voltage of 100 V to the hydraulic pump and various motors, and supplies a voltage of 10 V to the control unit 3.

[0018] The hydraulic power source GP supplies hydraulic pressure to a hydraulic device constituting the testing machine main body 2. The hydraulic power source GP supplies hydraulic pressure to, for example, a hydraulic actuator 18 to drive the hydraulic actuator 18. That is, the hydraulic actuator 18 is driven by the hydraulic pressure supplied from the hydraulic power source GP, and a piston rod 181 is extended and contracted. The hydraulic power source GP includes a hydraulic pump and a hydraulic control valve (not shown), and generates hydraulic pressure by driving the hydraulic pump. The hydraulic pump is supplied with power from a power source GE. The hydraulic control valve adjusts the hydraulic pressure output from the hydraulic power source GP.

[0019] The control unit 3 includes a signal input / output device 40 and a control device 50. The signal input / output device 40 constitutes an input / output interface circuit for transmitting and receiving signals between the testing machine main body 2, and in the first embodiment, has a first sensor amplifier 42, a second sensor amplifier 45, a third sensor amplifier 43, and a servo amplifier 44. The first sensor amplifier 42 is an amplifier that amplifies the test force measurement signal SG1 output by the load cell 14 to generate a test force measurement value FD, and outputs the test force measurement value FD to the control device 50. The second sensor amplifier 45 is an amplifier that amplifies the extension measurement signal SG3 output by the displacement sensor 15 to generate an extension measurement value ED, and outputs the extension measurement value ED to the control device 50. The third sensor amplifier 43 amplifies the displacement measurement signal SG2 output by the differential transformer 19, and outputs a displacement measurement signal A3 indicating the displacement measurement value XD to the control device 50 as a digital signal. The servo amplifier 44 is a device that controls the servo valve 20 under the control of the control device 50. The control device 50 calculates a command value dX of the displacement measurement value XD, and transmits a command signal A4 indicating the command value dX to the servo valve 20.

[0020] Based on an operation by a user, the control device 50 controls the operation of the testing machine main body 2. Furthermore, the control device 50 causes the testing machine main body 2 to execute a tensile test. In the first embodiment, the “user” includes an operator who operates the testing machine main body 2 .

[0021] The control device 50 includes a computer having a storage device such as a hard disk drive (HDD) or a solid state drive (SSD), an interface circuit with the signal input / output device 40, and various electronic circuits. An A / D converter is provided in the interface circuit with the signal input / output device 40, and the analog test force measurement signal SG1, elongation measurement signal SG3 and displacement measurement signal SG2 are converted into digital signals by the A / D converter. The control device 50 is not limited to a computer, and may be configured by one or more appropriate circuits such as an integrated circuit, such as an IC chip or an LSI.

[0022] FIG. 2 is a diagram showing an example of the configuration of the control device 50 according to the first embodiment. The control device 50 includes a control unit 52 . The testing machine main body 2 further includes an operation panel 51 . The operation panel 51 includes a microphone 511 , a touch panel 512 , and a push button switch 513 . The microphone 511 receives a voice from the user and generates a voice signal SW. The microphone 511 outputs the voice signal SW to the control unit 52. The touch panel 512 includes an LCD (Liquid Crystal Display) and displays various images on the LCD in accordance with instructions from the control unit 52. The touch panel 512 also includes a touch sensor arranged along the display surface of the LCD. The touch sensor detects a touch with a user's fingertip or pen, and transmits a detection signal to the control unit 52. The push button switch 513 includes a plurality of push button switches, accepts various operations from the user, and transmits operation signals corresponding to the operations to the control unit 52.

[0023] The control unit 52 is configured by, for example, a personal computer, and controls the operation of the control device 50. The control unit 52 includes a processor 53 and a memory . The processor 53 is composed of a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), and the like. The memory 54 is composed of a ROM (Read Only Memory), a RAM (Random Access Memory), and the like.

[0024] The control unit 52 is not limited to a personal computer, and may be configured by one or more appropriate circuits such as an integrated circuit such as an IC chip or an LSI. The control unit 52 may also be configured by, for example, a tablet terminal, a smartphone, or the like. The control unit 52 may also include programmed hardware such as a digital signal processor (DSP) or a field programmable gate array (FPGA). The control unit 52 may also include a system-on-a-chip (SoC)-FPGA.

[0025] [1-2. Configuration of the control unit] As shown in FIG. 2, the control unit 52 includes a communication unit 531, an operation control unit 532, a display control unit 533, a voice receiving unit 534, an extraction unit 535, a determination unit 536, an instruction unit 537, a correspondence memory unit 541, a sequence memory unit 542, and a test condition memory unit 543. Specifically, the processor 53 of the control unit 52 executes a control program stored in the memory 54 or a storage device, thereby functioning as a communication unit 531, an operation control unit 532, a display control unit 533, a voice receiving unit 534, an extraction unit 535, a determination unit 536, and an instruction unit 537. The processor 53 of the control unit 52 also executes a control program stored in the memory 54 or a storage device, thereby causing the memory 54 to function as a correspondence storage unit 541, a sequence storage unit 542, and a test condition storage unit 543.

[0026] The correspondence storage unit 541 stores the specific word KW and the instruction information CM for the test machine main body 2 in association with each other. The specific words KW are words preset by the user, and include a first word KW1, a second word KW2, and a third word KW3. The instruction information CM indicates an instruction to the test machine main body 2. The instruction information CM includes first instruction information CM1, second instruction information CM2, and third instruction information CM3. The first instruction information CM1 indicates an instruction corresponding to one operation of the test machine main body 2. The second instruction information CM2 indicates an instruction corresponding to multiple successive operations of the test machine main body 2. The third instruction information CM3 indicates an instruction to the test machine main body 2 to set test conditions. The first word KW1 is associated with the first instruction information CM1 and stored in the correspondence storage unit 541. The second word KW2 is associated with the second instruction information CM2 and stored in the correspondence storage unit 541. The third word KW3 is associated with the third instruction information CM3 and stored in the correspondence storage unit 541. The first word KW1 to the third word KW3 and the first command information CM1 to the third command information CM3 will be specifically described with reference to FIGS.

[0027] The sequence storage unit 542 stores a sequence SQ indicating a plurality of consecutive operations of the test machine main body 2. Each of the plurality of operations constituting the sequence SQ is stored in the correspondence storage unit 541 as, for example, first command information CM1. The sequence storage unit 542 stores a plurality of sequences SQ. Each of the plurality of sequences SQ is set by a user and stored in the sequence storage unit 542. Each of the plurality of sequences SQ is identified by a registration number. The registration number corresponds to an example of identification information.

[0028] The test condition storage unit 543 stores a plurality of test conditions CT executed by the testing machine main body 2. The plurality of test conditions CT are stored in the test condition storage unit 543 in advance. Each of the multiple test conditions CT is set by the user and stored in the test condition storage unit 543 in, for example, a file format. Each of the multiple test conditions CT is identified by a file number. The file number corresponds to an example of identification information. In the first embodiment, the test condition CT defines the test conditions for the tensile test. The test conditions CT include, for example, a first test condition CT1 in which position control is performed for the test force measurement value FD, and a second test condition CT2 in which speed control is performed for the elongation measurement value ED.

[0029] The communication unit 531 controls communication with the signal input / output device 40 shown in FIG. The communication unit 531 receives, for example, the test force measurement value FD, the elongation measurement value ED, and the displacement measurement value XD from the signal input / output device 40. In addition, the communication unit 531 transmits, for example, a command signal A4 indicating a command value dX to the signal input / output device 40.

[0030] Further, the communication unit 531 transmits various pieces of instruction information CM to, for example, the load cell 14, the displacement sensor 15, the servo valve 20, the hydraulic power source GP, and the power source GE in accordance with instructions from the instruction unit 537. The communication unit 531 transmits, for example, instruction information CM to set the offsets of the load cell 14 and the displacement sensor 15 to zero. The communication unit 531 also transmits, for example, instruction information CM to start up the hydraulic power source GP and the electric power source GE.

[0031] The operation control section 532 controls the operation of the testing machine main body 2 . For example, when a tensile test corresponding to the first test condition CT1 in which position control is performed for the test force measurement value FD is performed, the operation control unit 532 calculates a command value dX of the displacement measurement value XD so that the test force measurement value FD coincides with the test force target value FT. Then, the communication unit 531 transmits a command signal A4 indicating the command value dX to the servo amplifier 44 of the signal input / output device 40.

[0032] For example, when a tensile test corresponding to the second test condition CT2 in which speed control is performed on the elongation measurement value ED is performed, the operation control unit 532 calculates a command value dX for the displacement measurement value XD so that the elongation speed measurement value EVD, which is the amount of change per unit time of the elongation measurement value ED, coincides with the elongation speed target value EVT. Then, the communication unit 531 transmits a command signal A4 indicating the command value dX to the servo amplifier 44 of the signal input / output device 40.

[0033] The display control unit 533 controls the screen and images displayed on the LCD of the touch panel 512 . When the operation control unit 532 is performing a tensile test, the display control unit 533 displays, for example, a graph showing the relationship between at least one of the test force measurement value FD and the elongation measurement value ED and the displacement measurement value XD on the LCD of the touch panel 512. Furthermore, when the operation control unit 532 executes a tensile test corresponding to the first test conditions CT1, the display control unit 533 displays, for example, a screen showing the first test conditions CT1 on the LCD of the touch panel 512. When the operation control unit 532 executes a tensile test corresponding to the second test conditions CT2, the display control unit 533 displays, for example, a screen showing the second test conditions CT2 on the LCD of the touch panel 512.

[0034] The voice receiving unit 534 receives a voice from the user. Specifically, the voice receiving unit 534 receives a voice signal SW generated by the microphone 511 in response to the voice from the user. In the following description, for convenience, the audio signal SW is not limited to an analog signal, but also includes digital information, that is, the audio signal SW also includes audio information obtained by A / D converting the audio signal SW.

[0035] The extraction unit 535 extracts the specific word KW from the voice signal SW by voice recognition processing. The voice signal SW may include, for example, the worker's mutterings, conversations with other workers, etc. The extraction unit 535 removes the worker's mutterings, conversations with other workers, etc., contained in the voice signal SW to extract the specific word KW. In other words, the extraction unit 535 determines whether or not the audio signal SW contains the specific word KW stored in the correspondence storage unit 541, and extracts the specific word KW if the specific word KW is included. The extraction unit 535 may also determine the degree of coincidence with the specific word KW, and extract the specific word KW if the degree of coincidence is equal to or greater than a preset threshold value. The threshold value is, for example, 90%.

[0036] The determination unit 536 refers to the correspondence storage unit 541 to determine the instruction information CM corresponding to the specific word KW extracted by the extraction unit 535. In other words, the determination unit 536 reads out the instruction information CM corresponding to the specific word KW extracted by the extraction unit 535 from the correspondence storage unit 541, thereby determining the instruction information CM.

[0037] The instruction unit 537 outputs the instruction information CM determined by the determination unit 536 to the test machine main body 2. In the first embodiment, the instruction unit 537 outputs instruction information CM to the test machine main body 2 via the operation control unit 532 and the communication unit 531, for example. The instruction information CM will be further explained with reference to FIGS.

[0038] FIG. 3 is a table showing an example of the relationship between the first word KW1 and the first instruction information CM1. 3 shows the first table TB11. The first table TB11 is stored in the correspondence storage unit 541 shown in FIG. In the left column of the first table TB11, a first word KW1 is stored, and in the right column of the first table TB11, a first instruction information CM1 corresponding to the first word KW1 is stored.

[0039] For example, if the first word KW1 is "start test", the instruction unit 537 instructs the testing machine main body 2 to "start material test" as indicated by the first instruction information CM1. For example, if the first word KW1 is "test end", the instruction section 537 instructs the test machine main body 2 to "end the ongoing test" as indicated by the first instruction information CM1.

[0040] For example, if the first word KW1 is "start return", the instruction unit 537 instructs the servo valve 20 of the testing machine main body 2 to "return the hydraulic actuator to the origin position" as indicated by the first instruction information CM1. For example, if the first word KW1 is "stop", the instruction unit 537 instructs the servo valve 20 of the testing machine main body 2 to "stop the operation of the hydraulic actuator" as indicated in the first instruction information CM1.

[0041] For example, when the first word KW1 is "jog mode", the instruction section 537 instructs the test machine main body 2 to "switch to jog (manual) operation mode" as indicated by the first instruction information CM1. For example, when the first word KW1 is "test mode", the instruction section 537 instructs the test machine main body 2 to "enter a test start waiting state" as indicated by the first instruction information CM1.

[0042] For example, if the first word KW1 is "hydraulic source off", the instruction unit 537 instructs the hydraulic source GP of the testing machine main body 2 to "shut off the hydraulic source" as indicated by the first instruction information CM1. For example, if the first word KW1 is "shutdown", the instruction section 537 instructs the power source GE of the test equipment main body 2 to "cut off the power supply to the test equipment" as indicated by the first instruction information CM1.

[0043] For example, if the first word KW1 is "test force zero reset," the instruction unit 537 instructs the load cell 14 of the testing machine main body 2 to "reset the test force measurement value to zero," as indicated by the first instruction information CM1. For example, if the first word KW1 is "stroke zero reset", the instruction unit 537 instructs the differential transformer 19 of the testing machine main body 2 to "reset the displacement measurement value to zero" as indicated by the first instruction information CM1.

[0044] 3, when the operator speaks so that a voice including the first word KW1 is input to the microphone 511, the first instruction information CM1 corresponding to one action can be output to the testing machine main body 2. Therefore, even if the operator is located away from the testing machine main body 2 (operation panel 51), the operator can easily instruct the testing machine main body 2 to perform one action. This improves the operator's workability.

[0045] FIG. 4 is a table showing an example of the relationship between the second word KW2 and the second instruction information CM2. 4 shows the second table TB12. The second table TB12 is stored in the correspondence storage unit 541 shown in FIG. The second word KW2 is stored in the left column of the second table TB12, and the second instruction information CM2 corresponding to the second word KW2 is stored in the right column of the second table TB12.

[0046] For example, when the second word KW2 is "execute sequence XX", the instruction unit 537 instructs the test machine main body 2 to "execute preregistered sequence XX" as indicated in the second instruction information CM2. Here, "registration" indicates that the user sets the content of the second instruction information CM2 corresponding to the sequence SQ and stores it in the sequence storage unit 542. In the first embodiment, the sequence SQ indicates an instruction corresponding to a plurality of consecutive operations of the test machine main body 2. The "XX" in the "sequence XX" indicates identification information of the sequence SQ stored in advance in the sequence storage unit 542. The "XX" in the "sequence XX" is, for example, a registration number. The sequence SQ is stored in the sequence storage unit 542 shown in FIG.

[0047] For example, when the second word KW2 is "test preparation", the instruction unit 537 instructs the testing machine main body 2 to "perform the 'jig distance movement' operation after performing calibration" as indicated in the second instruction information CM2. Here, "jig distance movement" refers to moving the lower grip 22 by the hydraulic actuator 18 so that the distance between the upper grip 21 and the lower grip 22 becomes a predetermined distance that has been set in advance, as shown in FIG.

[0048] For example, when the second word KW2 is "emergency stop", the instruction unit 537 instructs the testing machine main body 2 to "stop the operation of the hydraulic actuator and perform the 'hydraulic source off' operation" as shown in the second instruction information CM2. The operation of the hydraulic actuator 18 is stopped by controlling the servo valve 20. "Hydraulic source off" means to stop the operation of the hydraulic source GP as shown in FIG. 3.

[0049] 4, when the operator speaks so that a voice including the second word KW2 is input to the microphone 511, the second instruction information CM2 corresponding to a series of multiple actions can be output to the testing machine main body 2. Therefore, even if the operator is located away from the testing machine main body 2 (operation panel 51), the operator can easily instruct the testing machine main body 2 to perform a series of multiple actions. This improves the operator's workability.

[0050] FIG. 5 is a table showing an example of the relationship between the third word KW3 and the third instruction information CM3. 5 shows the third table TB13. The third table TB13 is stored in the correspondence storage unit 541 shown in FIG. The third word KW3 is stored in the left column of the third table TB13, and the third command information CM3 corresponding to the third word KW3 is stored in the right column of the third table TB13.

[0051] For example, if the third word KW3 is "Read file YY", the instruction unit 537 outputs an instruction to the test machine main body 2 indicating that "Read the test condition file with file number YY, set it as the test condition, and execute the "test mode" operation" as shown in the third instruction information CM3. The test condition file is stored in the test condition storage unit 543 shown in Fig. 2. That is, the test condition file having the file number YY is read out from the test condition storage unit 543. The "test mode" operation means a state in which the device is waiting for the start of a test, as shown in FIG.

[0052] 5, the operator speaks so that a voice including the third word KW3 is input to the microphone 511, whereby the third instruction information CM3 for setting the test conditions CT for the testing machine body 2 can be output to the testing machine body 2. Therefore, even if the operator is located away from the testing machine body 2 (operation panel 51), the operator can easily set the desired test conditions CT for the testing machine body 2. This improves the operator's workability.

[0053] [1-3. Processing of the control unit] Next, the process executed by the control unit 52 will be described with reference to FIG. FIG. 6 is a flowchart showing an example of a process executed by the control unit 52. In the first embodiment, a first table TB11 shown in Fig. 3, a second table TB12 shown in Fig. 4, and a third table TB13 shown in Fig. 5 are stored in advance in the correspondence storage unit 541. A plurality of sequences SQ are stored in advance in the sequence storage unit 542, and a plurality of test conditions CT are stored in advance in the test condition storage unit 543.

[0054] 6, first, in step S101, the voice receiving unit 534 receives a voice from the user. Specifically, the voice receiving unit 534 receives a voice signal SW generated by the microphone 511 in response to the voice from the user. Next, in step S103, the extraction unit 535 determines whether or not a specific word KW has been extracted from the voice signal SW by the voice recognition process. When the extraction unit 535 determines that the specific word KW has not been extracted (step S103; NO), the process proceeds to step S105. Then, in step S105, the display control unit 533 displays a message indicating that the specific word KW has not been extracted on the LCD of the touch panel 512. After that, the process returns to step S101.

[0055] When the extraction unit 535 determines that the specific word KW has been extracted (step S103; YES), the process proceeds to step S107. Then, in step S107, the determination unit 536 refers to the correspondence storage unit 541 to determine the instruction information CM corresponding to the specific word KW. Next, in step S109, the instruction unit 537 determines whether or not the instruction information CM determined by the determination unit 536 is the first instruction information CM1.

[0056] If the instruction unit 537 determines that the instruction information CM is not the first instruction information CM1 (step S109; NO), the process proceeds to step S115. If the instruction unit 537 determines that the instruction information CM is the first instruction information CM1 (step S109; YES), the process proceeds to step S111. Then, in step S111, the instruction unit 537 outputs the first instruction information CM1 to the test machine main body 2. Next, in step S113, the control unit 52 determines whether or not one action corresponding to the first instruction information CM1 has been completed. When the control unit 52 determines that one operation corresponding to the first command information CM1 has not been completed (step S113; NO), the process goes into a standby state. When the control unit 52 determines that one operation corresponding to the first command information CM1 has been completed (step S113; YES), the process returns to step S101.

[0057] If NO in step S109, in step S115, the instruction unit 537 determines whether or not the instruction information CM determined by the determination unit 536 is the second instruction information CM2. If the instruction unit 537 determines that the instruction information CM is not the second instruction information CM2 (step S115; NO), the process proceeds to step S121. If the instruction unit 537 determines that the instruction information CM is the second instruction information CM2 (step S115; YES), the process proceeds to step S117. Then, in step S117, the instruction section 537 outputs the second instruction information CM2 to the test machine main body 2. Next, in step S119, the control unit 52 determines whether or not the multiple actions corresponding to the second instruction information CM2 have been completed. If the control unit 52 determines that the multiple actions corresponding to the second command information CM2 have not been completed (step S119; NO), the process goes into a standby state. If the control unit 52 determines that the multiple actions corresponding to the second command information CM2 have been completed (step S119; YES), the process returns to step S101.

[0058] In the case of NO in step S115, in step S121, the instruction unit 537 determines that the instruction information CM determined by the determination unit 536 is the third instruction information CM3. Then, in step S123, the instruction unit 537 outputs the third instruction information CM3 to the test machine main body 2. Next, in step S125, the control unit 52 determines whether or not setting of the test conditions CT corresponding to the third instruction information CM3 is completed. If the control unit 52 determines that the setting of the test conditions CT corresponding to the third command information CM3 is not completed (step S125; NO), the process goes into a standby state. If the control unit 52 determines that the setting of the test conditions CT corresponding to the third command information CM3 is completed (step S125; YES), the process returns to step S101.

[0059] 6, the voice receiving unit 534 receives the voice signal SW generated by the microphone 511 in response to the voice from the user, and the extracting unit 535 extracts the specific word KW from the voice signal SW by voice recognition processing. Then, the determining unit 536 refers to the correspondence storage unit 541 to determine the instruction information CM corresponding to the specific word KW extracted by the extracting unit 535, and the instruction unit 537 outputs the instruction information CM to the test machine main body 2. Therefore, when the operator speaks so that a voice including the specific word KW is input to the microphone 511, the instruction information CM corresponding to the specific word KW can be output to the testing machine main body 2. Therefore, even if the operator is located away from the testing machine main body 2 (operation panel 51), the operator can easily instruct the testing machine main body 2 with the instruction information CM. This improves the operator's workability. Furthermore, in the material testing machine 1, as a test preparation operation, an operator may set heavy objects such as the upper grip 21 and the lower grip 22 in the testing machine body 2. In such a case, even if the operator is located away from the testing machine body 2 during the test preparation operation, the operator can easily output the instruction information CM to the testing machine body 2. Therefore, the safety of the operator's work can be improved.

[0060] [2. Second embodiment] [2-1. Configuration of particle analyzer] FIG. 7 is a diagram showing an example of the configuration of a particle analyzer 6 according to the second embodiment. As shown in FIG. 7, the particle analyzer 6 includes an analyzer main body 6A and a control device 50. The particle analyzer 6 analyzes images of the particles PT of the powder sample SP contained in a sample image PS obtained by flowing the liquid sample SL, in which particles PT of the powder sample SP are dispersed, through the flow path 77 at a predetermined speed VA and photographing the liquid sample SL at a predetermined period TA. Furthermore, the particle analyzer 6 analyzes the particle properties of the particles PT of the powder sample SP based on the results of the image analysis.

[0061] The powder sample SP is, for example, a powder of an industrial product such as a pigment, a cosmetic powder, a toner, a particulate catalyst, an abrasive, a powdered medicine, a synthetic resin powder, fine ceramic particles, a metal particle, etc. The particle property is typically a particle shape, and includes a circle equivalent diameter, a circularity, an aspect ratio, etc. The particle analyzer 6 analyzes the images of the particles PT of the powder sample SP, for example, by the dynamic image analysis method defined in JIS Z8827-2. The size of the particles PT of the powder sample SP is, for example, 5 μm to 100 μm.

[0062] The analysis device main body 6A shown in FIG. 7 generates a sample image PS of a liquid sample SL in which particles PT are dispersed. As shown in FIG. 7, the analysis device main body 6A includes a flow cell 62, a liquid sample supplying mechanism 90, an illumination unit 60, a camera 80, and a focusing mechanism . The flow cell 62 is an optically nearly transparent measurement container formed in a nearly rectangular plate shape. An inlet 64A for introducing a liquid sample SL is formed in an upper end surface 66A of the flow cell 62, and an outlet 64B for discharging the liquid sample SL is formed in a lower end surface 66B of the flow cell 62. A flow path 77 is formed linearly from the inlet 64A to the outlet 64B. The flow cell 62 of the second embodiment is provided with a focus target (not shown) for focusing, and the control unit 52 is configured to adjust the focus of the camera 80 based on the focus target.

[0063] The liquid sample supply mechanism 90 is a mechanism for feeding a predetermined amount of the liquid sample SL into the flow cell 62 per unit time, and includes a liquid feed pump 82. In other words, the liquid feed pump 82 causes the liquid sample SL to flow through the flow path 77 at a predetermined speed VA. The predetermined speed VA is, for example, 14.5 mm / sec. In the second embodiment, an inlet pipe 76 extending from a liquid sample storage container 74 that stores a liquid sample SL is connected to an inlet 64A of a flow cell 62. One end of a discharge pipe 78 is connected to the outlet 64B, and the other end of the discharge pipe 78 is connected to the suction side of a liquid delivery pump 82. By operating the liquid feed pump 82, the liquid sample SL in the liquid sample storage container 74 flows from the inlet 64A into the flow path 77 of the flow cell 62, passes through the flow path 77, and is discharged from the outlet 64B. A waste liquid pipe 79 is connected to the discharge side of the liquid delivery pump 82, and the liquid sample discharged by the liquid delivery pump 82 is collected in a waste liquid tank 83 through the waste liquid pipe 79. The liquid delivery pump 82 may be provided on the side of the introduction pipe 76.

[0064] The illumination unit 60 includes a light source device 60A that irradiates the flow cell 62 with measurement light 84. The light source device 60A of the second embodiment irradiates the measurement light 84, which is substantially parallel light, from a direction substantially perpendicular to the flow path 77 of the flow cell 62. The light source device 60A includes a light source having a light emitting element such as an LED (Light Emitting Diode) light source or a laser light source, and a collimating optical system that converts the light emitted from the light source into parallel light. The light source device 60A may include a planar light source that emits light in a planar manner, such as a COB (Chip On Board) type LED, as the light source.

[0065] The camera 80 is disposed at a position facing the illumination unit 60 across the flow cell 62, and captures an image of a portion of the flow cell 62 irradiated with the measurement light 84 at a predetermined period TA in accordance with instructions from the control unit 52. The camera 80 of the second embodiment includes an image sensor 86, which is an imaging sensor, and a telecentric microscope 88. The imaging element 86 is composed of a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), etc. The telecentric microscope 88 is a telecentric optical system that forms an image of the irradiated portion of the flow cell 62 on an imaging surface 86A of the imaging element 86, and includes a telecentric lens 89 disposed opposite the flow cell 62.

[0066] The shooting speed of the camera 80 is, for example, 8 FPS. That is, the predetermined cycle TA is 0.125 seconds. The predetermined cycle TA is set so as to satisfy the following condition. That is, the predetermined speed VA and the predetermined period TA are each set so that the particles flowing inside the flow path 77 are not included in two successively captured images of the sample PS. In other words, the predetermined speed VA and the predetermined period TA are set so as to satisfy the following formula (1). VA>LA / TA (1) Here, the length LA indicates the length of the particle PT in the flow direction in the field of view of the camera 80. For example, the length LA is 1.8 mm. In this case, the value of the right side of the formula (1) is 14.4 (= 1.8 / 0.125) mm / sec, which satisfies the formula (1) when the predetermined speed VA is 14.5 mm / sec.

[0067] In this way, the specified speed VA and the specified period TA are each set so that a particle PT flowing within the flow path 77 is not included in two consecutively captured images of the sample PS, thereby preventing images of the same particle PT from being captured multiple times.

[0068] The focus mechanism 70 is a mechanism for varying the focus of the telecentric microscope 88, and includes a lens driving mechanism 87. The lens driving mechanism 87 is a mechanism for varying the focus of the camera 80 by driving a telecentric lens 89 along the optical axis A of the telecentric optical system under the control of the control unit 52.

[0069] The control device 50 has substantially the same configuration as the control device 50 according to the first embodiment shown in FIG. That is, the control device 50 includes a control unit 52. The analysis device main body 6A further includes an operation panel 51. The operation panel 51 includes a microphone 511 , a touch panel 512 , and a push button switch 513 . The microphone 511 receives a voice from the user and generates a voice signal SW corresponding to the voice. The microphone 511 outputs the generated voice signal SW to the control unit 52. The touch panel 512 includes an LCD (Liquid Crystal Display) and displays various images on the LCD in accordance with instructions from the control unit 52. The touch panel 512 also includes a touch sensor arranged along the display surface of the LCD. The touch sensor detects a touch with a user's fingertip or pen, and transmits a detection signal to the control unit 52. The push button switch 513 includes a plurality of push button switches, accepts various operations from the user, and transmits operation signals corresponding to the operations to the control unit 52.

[0070] [2-2. Control Unit Configuration] The control unit 52 is configured by, for example, a personal computer, and controls the operation of the analysis device main body 6A. The control unit 52 includes a processor 53, a memory 54, a storage device such as an HDD or SSD, and an interface circuit for connecting the camera 80, etc. The processor 53 is composed of a CPU, an MPU, etc. The memory 54 is composed of a ROM, etc.

[0071] The control unit 52 is not limited to a personal computer, and may be configured by one or more appropriate circuits such as an integrated circuit such as an IC chip or an LSI. The control unit 52 may also be configured by, for example, a tablet terminal, a smartphone, or the like. The control unit 52 may also include programmed hardware such as a DSP, an FPGA, etc. The control unit 52 may also include an SoC-FPGA.

[0072] Similar to the control unit 52 shown in FIG. 2, the control unit 52 includes a communication unit 531, an operation control unit 532, a display control unit 533, a voice receiving unit 534, an extraction unit 535, a determination unit 536, an instruction unit 537, a correspondence memory unit 541, and a sequence memory unit 542. The control unit 52 includes a measurement condition storage unit 544 and an image storage unit 545 in place of the test condition storage unit 543 shown in FIG. Specifically, the processor 53 of the control unit 52 executes a control program stored in the memory 54 or a storage device, thereby functioning as a communication unit 531, an operation control unit 532, a display control unit 533, a voice reception unit 534, an extraction unit 535, a determination unit 536, and an instruction unit 537. The processor 53 of the control unit 52 also executes a control program stored in the memory 54 or a storage device, thereby causing the memory 54 to function as a correspondence storage unit 541, a sequence storage unit 542, a measurement condition storage unit 544, and an image storage unit 545.

[0073] In the following description, differences from the control unit 52 shown in FIG. 2 will be mainly described, and a description of the same configuration as the control unit 52 shown in FIG. 2 will be omitted. However, the testing machine main body 2 in the explanation of the control unit 52 shown in FIG. 2 corresponds to the analysis device main body 6A in the control unit 52 shown in FIG.

[0074] The measurement condition storage unit 544 stores a plurality of measurement conditions AT executed by the analysis device main body 6A. The plurality of measurement conditions AT are stored in the measurement condition storage unit 544 in advance. Each of the plurality of measurement conditions AT is set by the user and stored in, for example, a file format in the measurement condition storage unit 544. Each of the plurality of measurement conditions AT is identified by a file number. The file number corresponds to an example of identification information. The measurement conditions AT include conditions for generating the sample image PS. Specifically, the measurement conditions AT include, for example, a predetermined speed VA at which the liquid sample SL flows in the flow channel 77 shown in Fig. 7, an image capturing speed (predetermined period TA) of the camera 80 shown in Fig. 7, and a length LA in the flow direction of the particle PT in the field of view of the camera 80 shown in Fig. 7. The measurement conditions AT may also include conditions for analyzing the sample image PS.

[0075] The image storage unit 545, in accordance with instructions from the operation control unit 532, stores the sample images PS obtained by photographing the liquid sample SL with the camera 80 at a predetermined period TA.

[0076] The communication unit 531 controls communication with the analysis device main body 6A shown in FIG. In other words, the communication unit 531 controls communication with each part of the analysis device main body 6A. Specifically, the communication unit 531 controls communication with each of the liquid sample supply mechanism 90, the illumination unit 60, the camera 80, and the focus mechanism 70, for example.

[0077] The operation control unit 532 adjusts the autofocus of the camera 80 and adjusts the timing of shooting by the camera 80. The operation control unit 532 adjusts the focus of the camera 80 (telecentric microscope 88) based on the captured image of the focus target of the flow cell 62. Specifically, the operation control unit 532 captures the captured image of the camera 80, and determines the deviation between the focus of the camera 80 and the focus target based on the captured state of the focus target shown in the captured image. Then, the operation control unit 532 controls the lens driving mechanism 87 so that the telecentric lens 89 moves to a position that eliminates the deviation in focus. In this way, the operation control unit 532 can adjust the focus of the camera 80 to the focus target. The operation control unit 532 also controls the camera 80 to capture the liquid sample SL at a predetermined period TA and generate a sample image PS. The operation control unit 532 also controls the image storage unit 545 to store the generated sample image PS.

[0078] FIG. 8 is a table showing an example of the relationship between the first word KW1 and the first instruction information CM1. 8 shows the first table TB21. The first table TB21 is stored in the correspondence storage unit 541 shown in FIG. In the left column of the first table TB21, the first word KW1 is stored, and in the right column of the first table TB21, the first instruction information CM1 corresponding to the first word KW1 is stored.

[0079] For example, when the first word KW1 is "start water supply", the instruction unit 537 instructs the analyzer body 6A to "operate the water supply pump" as shown in the first instruction information CM1. The water supply pump is a pump that supplies water to the liquid sample storage container 74 shown in FIG. For example, if the first word KW1 is "stop water supply", the instruction unit 537 instructs the analyzer main body 6A to "stop the water supply pump" as indicated in the first instruction information CM1.

[0080] For example, when the first word KW1 is "pump speed XX", the instruction unit 537 instructs the analyzer body 6A to "change the liquid delivery pump speed to XX" as shown in the first instruction information CM1. Here, the "liquid delivery pump speed" refers to the flow speed of the liquid sample SL flowing through the flow path 77 (predetermined speed VA, for example, 14.5 mm / sec).

[0081] 8, the operator speaks so that a voice including the first word KW1 is input to the microphone 511, whereby the first instruction information CM1 corresponding to one operation can be output to the analysis device main body 6A. Therefore, even if the operator is located away from the analysis device main body 6A (operation panel 51), the operator can easily instruct the analysis device main body 6A to perform one operation. This improves the operator's workability.

[0082] FIG. 9 is a table showing an example of the relationship between the second word KW2 and the second instruction information CM2. 9 shows the second table TB22. The second table TB22 is stored in the correspondence storage unit 541 shown in FIG. The second word KW2 is stored in the left column of the second table TB22, and the second instruction information CM2 corresponding to the second word KW2 is stored in the right column of the second table TB22.

[0083] For example, when the second word KW2 is "execute sequence XX", the instruction unit 537 instructs the analyzer body 6A to "execute a sequence XX registered in advance" as indicated in the second instruction information CM2. Here, "registration" indicates that the user sets the content of the second instruction information CM2 corresponding to the sequence SQ and stores it in the sequence storage unit 542. In the second embodiment, the sequence SQ indicates an instruction corresponding to a plurality of consecutive operations of the analysis device main body 6A. The "XX" in the "sequence XX" indicates identification information of the sequence SQ stored in advance in the sequence storage unit 542. The "XX" in the "sequence XX" is, for example, a registration number. The sequence SQ is stored in the sequence storage unit 542 shown in FIG.

[0084] For example, when the second word KW2 is "XX seconds water supply", the instruction unit 537 instructs the analysis device main body 6A to "operate the water supply pump for XX seconds" as shown in the second instruction information CM2. That is, the instruction unit 537 instructs the analysis device main body 6A to perform a plurality of successive operations, such as starting the operation of the water supply pump and stopping the operation of the water supply pump when the water supply pump has operated for XX seconds.

[0085] 9, when the operator speaks so that a voice including the second word KW2 is input to the microphone 511, second instruction information CM2 corresponding to a series of multiple actions can be output to the analysis device main body 6A. Therefore, even if the operator is located away from the analysis device main body 6A (operation panel 51), the operator can easily instruct the analysis device main body 6A to perform a series of multiple actions. This improves the operator's workability.

[0086] FIG. 10 is a table showing an example of the relationship between the third word KW3 and the third instruction information CM3. 10 shows the third table TB23. The third table TB23 is stored in the correspondence storage unit 541 shown in FIG. The third word KW3 is stored in the left column of the third table TB23, and the third command information CM3 corresponding to the third word KW3 is stored in the right column of the third table TB23.

[0087] For example, if the third word KW3 is "Read file No. YY", the instruction unit 537 outputs an instruction to the testing machine main body 2 indicating that "read the measurement condition file with file number YY, set it as the measurement condition, and execute the "measurement mode" operation" as shown in the third instruction information CM3. The measurement condition file is stored in the measurement condition storage unit 544 shown in Fig. 7. That is, the measurement condition file with the file number YY is read out from the measurement condition storage unit 544. The measurement condition file indicates the measurement condition AT. The "measurement mode" operation means that the tester main body 2 is put into a state waiting for the start of a measurement operation under measurement conditions AT.

[0088] 10, the operator speaks so that a voice including the third word KW3 is input to microphone 511, whereby third instruction information CM3 for setting measurement conditions AT for analysis device main body 6A can be output to analysis device main body 6A. Therefore, even if the operator is located away from analysis device main body 6A (operation panel 51), the operator can easily set the desired measurement conditions AT for analysis device main body 6A. This improves the operator's workability.

[0089] [3. Aspects and Effects] It will be understood by those skilled in the art that the above-described embodiment is a specific example of the following aspects.

As a result, the operator's workability can be improved. In addition, in the case of a material testing machine, an operator may set heavy objects such as an upper grip and a lower grip on the main body of the testing machine as part of test preparation work. In such a case, even if the operator is located away from the main body of the testing machine during the test preparation work, the operator can easily output instruction information to the main body of the testing machine.

Therefore, by the operator uttering a voice including the third word so that the voice receiving unit can receive it, the third instruction information for setting test conditions for the testing machine body can be output to the testing machine body. Therefore, even if the operator is located away from the testing machine body, the operator can easily set the desired test conditions for the testing machine body. As a result, the operator's workability can be improved.

Then, a determining unit refers to the corresponding storage unit to determine instruction information corresponding to the specific word extracted by the extracting unit, and an instruction unit outputs the instruction information determined by the determining unit to the analyzer body. Therefore, when the operator speaks in a manner that allows the voice receiving unit to receive a voice containing the specific word, instruction information corresponding to the specific word can be output to the analysis device body. Therefore, even if the operator is located at a distance from the analysis device body, the operator can easily output instruction information to the analysis device body. As a result, the operator's workability can be improved.

Therefore, the first instruction information corresponding to one operation can be output to the analysis device body by the operator uttering a voice including the first word stored in the correspondence storage unit in association with the first instruction information so that the voice receiving unit can receive the voice. Therefore, even if the operator is located at a position away from the analysis device body, the operator can easily instruct the analysis device body to perform one operation.

Therefore, by the operator uttering a voice including the second word stored in the correspondence storage unit in association with the second instruction information so that the voice receiving unit receives the voice, the second instruction information corresponding to a plurality of consecutive actions can be output to the analysis device main body. Therefore, even if the operator is located at a position away from the analysis device main body, the operator can easily instruct the analysis device main body to perform a plurality of consecutive actions. As a result, the operator's workability can be improved.

[0104] (Section 8) In a particle analysis device described in any one of paragraphs 5 to 7, the instruction information includes third instruction information for setting measurement conditions for the analysis device main body, and the correspondence memory unit stores a third word, which is the specific word corresponding to the third instruction information, in correspondence with the third instruction information.

Therefore, even if the operator is located at a distance from the analyzer body, the operator can easily set the desired measurement conditions for the analyzer body. As a result, the operator's workability can be improved.

[0106] [4. Other embodiments] The tensile tester 1 according to the first embodiment is merely an example of an embodiment of the material testing machine according to the present invention, and can be modified and applied as desired without departing from the spirit of the present invention. The particle analyzer 6 according to the second embodiment is merely an example of an embodiment of the analysis device according to the present invention, and can be modified and applied as desired without departing from the spirit of the present invention.

[0107] For example, in the first embodiment, a case will be described in which the material testing machine is a tensile testing machine 1, but the present invention is not limited to this. The material testing machine may apply a test force to the test piece TP and deform the test piece TP to perform a material test. For example, the material testing machine may be a compression testing machine, a bending testing machine, or a torsion testing machine.

[0108] In the second embodiment, the particle analyzer 6 analyzes an image of the particles PT of the powder sample SP by the dynamic image analysis method defined in JIS Z8827-2, but is not limited to this. The particle analyzer 6 may generate a sample image PS of the liquid sample SL in which the particles PT are dispersed. In other words, the analysis of the image of the particles PT using the sample image PS may be performed by a device other than the particle analyzer 6.

[0109] In the present embodiment, the case where the command information CM includes the first command information CM1, the second command information CM2, and the third command information CM3 has been described, but is not limited thereto. The command information CM may include at least one of the first command information CM1, the second command information CM2, and the third command information CM3.

[0110] 1, 2, and 7 show functional configurations, and the specific implementation form is not particularly limited. In other words, it is not necessary to implement hardware corresponding to each functional unit individually, and it is of course possible to implement a configuration in which one processor executes a program to realize the functions of multiple functional units. Also, some of the functions realized by software in the above embodiments may be realized by hardware, or some of the functions realized by hardware may be realized by software.

[0111] In addition, the processing units in the flowchart shown in Fig. 6 are divided according to the main processing contents in order to facilitate understanding of the processing of the control unit 52. There is no limitation to the manner of division or names of the processing units shown in the flowchart of Fig. 6, and the processing units can be further divided according to the processing contents, or one processing unit can be divided to include further processes. In addition, the processing order of the above flowchart is not limited to the example shown in the figure.

[0112] 2 and 7, in this embodiment, the processor 53 included in the control unit 52 executes a control program stored in the memory 54 or a storage device. This control program can also be recorded in a computer-readable recording medium. As the recording medium, a magnetic or optical recording medium or a semiconductor memory device can be used. Specifically, examples of such recording media include portable or fixed recording media such as flexible disks, HDDs, CD-ROMs (Compact Disk Read Only Memory), DVDs, Blu-ray (registered trademark) Discs, magneto-optical disks, flash memories, and card-type recording media. The recording medium may be a non-volatile storage device such as a RAM, a ROM, or a HDD that is an internal storage device included in the control unit 52. The control program may be stored in a server device or the like, and the control program may be downloaded from the server device to the control unit 52. [Explanation of symbols]
