  An embodiment in which a testing machine according to the present invention is applied to a material testing machine will be described with reference to FIGS. As shown in FIG. 2, the material testing machine includes a testing machine main body 100 and an operation panel 200 that controls the testing machine main body 100. The operation panel 200 is provided with a terminal (connector) for mounting a portable recording medium 300 such as a USB memory. Hereinafter, the operation panel will be described as the control device 200.

The tester main body 100 and the control device 200 will be described in detail with reference to FIG.
The testing machine main body 100 has a fixed table 101, and a pair of left and right screw rods 102 and 103 are erected on the fixed table 101, and a yoke 104 is horizontally mounted on the upper portions of the screw rods 102 and 103. . A cross head 105 is supported on each of the screw rods 102 and 103 so as to be movable up and down. The screw rods 102 and 103 are rotationally driven by a servo motor 107 via a transmission 106, whereby the cross head 105 is moved up and down.

  When a load is applied to the specimen TP held by the upper grip 108 and the lower grip 109 due to the rise of the crosshead 105, the specimen TP is deformed. The load is detected as a load (test force) by a load cell 110 attached to the upper part of the crosshead 105, and the deformation amount is detected as an extension amount by a displacement meter 111 attached to the specimen TP. The rotation amount of the servo motor 107 is detected by the rotation sensor 112.

  The control device 200 sets test conditions performed by the tester main body 100, records measurement data, and processes the data. In this embodiment, graph image data is created from measurement data and compressed in JPEG format. The compressed image data is recorded together with a DPOF (Digital Print Order Format) file described later. Such a control device 200 includes a CPU 201, a ROM 202, a RAM 203, a touch panel monitor 204, a USB connector 205, A / D converters 206, 207 and 208, and a D / A converter 209. A USB memory 300 is attached to the USB connector 205, and an image data file and a DPOF file are recorded. That is, the image data is stored in accordance with the DPOF file standard for printing by connecting a digital camera and a printer.

  The CPU 201 executes various calculations by executing a test execution / data processing program stored in the ROM 202 using the RAM 203 as a work area. The main processes executed by this program are a test condition setting process, a test execution process, and a measurement data process.

  In the test condition setting process, the CPU 201 displays a test condition setting screen on the touch panel monitor 204. On this setting screen, a dialog box and input buttons for setting test conditions in an interactive format are displayed. The operator performs character input and button operation via the dialog box, and sets test conditions, test result display format, and the like. For example, when performing a tensile test, the operator inputs the displacement speed, that is, the speed of the crosshead 105 from the touch panel monitor 204.

  In the test execution process, the following process is executed. An analog signal measured by a load cell 105 that measures a load acting on the specimen TP and a displacement meter 111 that measures deformation of the specimen TP due to the load is sent at predetermined sample times via A / D converters 206 and 207. As digital data. The CPU 201 stores the measurement data in the measurement data storage area, calculates the load of the specimen TP and the change rate of the deformation amount based on the measurement data, and loads the specimen TP at the target test speed. A motor drive signal is generated and output to the motor 107 via the D / A converter 209.

  In the measurement data processing, the following processing is executed. During the test execution, the CPU 201 displays the deformation amount and load numerical data on the touch panel monitor 204 in real time using the deformation amount and the load stored in the measurement data storage area. Also, display image data of a graph representing the relationship between the deformation amount and the load is generated and displayed on the touch panel monitor 204 in real time.

  After the test is completed, the CPU 201 performs data processing based on the stored measurement data, creates graph image data from the measurement result after the data processing, and records it in the USB memory 300 in JPEG format. The image data recorded in the USB memory 300 is, for example, a load-displacement characteristic graph created based on load data and displacement data. The title of the graph, the units of the vertical axis and horizontal axis of the graph, that is, the character data superimposed on the image can be input at an arbitrary position according to the user's preference. In addition, strength data such as the maximum point, yield point, and break point that briefly indicate the test result of the graph can be arbitrarily selected from a plurality of strength data prepared in advance according to the user's preference and superimposed on the graph. . An automatic print file that is a DPOF file is also created together with the JPEG image data. If necessary, an automatic transmission file and an automatic reproduction file, which are DPOF files, are also created.

  Data processing instructions after the end of the test are performed using the touch panel monitor 204. On the display screen of the monitor, a dialog box and an input button for instructing data processing interactively are displayed. The operator can create favorite image data by inputting characters using a dialog box or by using various buttons.

  When the USB memory 300 is set in a printer (not shown), an image data file and an automatic print file that is a DPOF file are read by the printer, and a graph in which character data is superimposed on image data that is a load-displacement characteristic graph (see, for example, FIG. 7). ) Is printed on the printer.

  Here, DPOF will be described in detail. DPOF is one of recording formats for digital cameras, and can record information for automatically printing images taken with a print service or a home printer. The DPOF file is recorded together with the image data file. That is, a DCIM directory and a MISC directory are constructed under the root directory, an image data file is recorded in the DCIM directory, and a DPOF file is recorded in the MISC directory.

  Usually, in the MISC directory, an automatic print file (AUTOPRINT.MRK), a UNICODE character string description file (UNICODE.MRK), an automatic transmission file (AUTOXFER.MRK), and an automatic reproduction file (AUTOPLAYN.MRK) are generated.

  The automatic print file is assigned with areas for defining general information, user information, print job information, image source information, various setting information, and vendor functions. Areas for defining general information, user information, destination information, message information, process job information, image source information, and data information are assigned to the automatic transmission file. Areas defining general information, user information, auto play job information, image source information, various setting information, video information, audio information, and vendor functions are assigned to the auto play file.

  In this embodiment, the number of prints and the like are described in the print job information column of the automatic print file, and the name of the image file to be printed is described in the image source information column. Follow the steps to print an image file.

  With reference to FIG. 4 to FIG. 6, display contents and operation procedures on the touch panel monitor 204 during and after the test will be described.

  FIG. 4 is a display example during the test. A curve of displacement and load of the specimen TP to be loaded is drawn along with the test. Test force and displacement are displayed in real time. Various units of the horizontal axis and the vertical axis can be set in the test condition setting process.

When the box 410 is touched, the screen is switched to a file name input screen (not shown), and a file name is input from this screen. When the box 411 is touched, the screen is switched to a print number input screen (not shown), and the number of prints is input from this screen.

  Thereafter, when the OK button 405 is operated, the graph image data is stored in the DCIM folder of the USB memory 300 with the input file name, and the number of prints is stored in the MISC folder as an automatic print file. In the USB memory 300, a DCIM folder and a MISC folder are created in advance. When the cancel button 406 is operated, a transition is made to the initial screen of FIG.

  When data is stored in the USB memory 300 by the operation of the OK button 405, the display screen is changed to the display screen of FIG. When the result insertion button 401 is operated, a transition is made to the display screen of FIG. In the display screen of FIG. 5C, the fields 404 of “maximum point test force”, “maximum point displacement”, “breaking point test force”, and “breaking elongation” are displayed, and a check box 404B is displayed at the top of each item. Is displayed. When the box 404B is pressed, the color in the box changes from white to black, indicating that it has been selected. On the right side of these display fields 404, an OK button 405 and a cancel button 406 are displayed. In the display example of FIG. 5C, “maximum point test force” and “breaking point test force” are selected. When the OK button 405 is operated, a transition is made to the screen shown in FIG.

  As shown in FIG. 6A, the test results relating to the “maximum point test force” and the “breaking point test force”, which are the results selected by the user, are displayed in the display area 407 in the graph. The maximum point test force and the breaking line test force are extracted based on measurement data stored in the RAM 203 of the control device 200.

  When the comment insertion button 402 is operated on the screen of FIG. 6A, the display screen is changed to the display screen of FIG. In the display screen of FIG. 6B, a column 408 for inserting an arbitrary comment is displayed. In the comment insertion field 408, a character input button 408a is further displayed. Similar to the display screen of FIG. 5C, an OK button 405 and a cancel button 406 are also displayed.

Drawn.

The material testing machine described above can provide the following operational effects.
(1) Test result image data, for example, a graph, can be created by the test execution / data processing control device without the need for a data processing device such as a personal computer. The image data is stored in the USB memory in accordance with the DPOF file standard for printing by connecting a digital camera and a printer. Therefore, if the USB memory is set in the printer, the graph can be printed.
(2) An arbitrary comment on the graph can be input with the character input button of the touch panel monitor 204, and a data processing device such as a personal computer for editing the graph is unnecessary.
(3) Test data to be printed together with the graph, for example, the maximum test force and the maximum breaking point can be selected on the touch panel monitor 204. This selection is also automatically extracted from the test result data stored in the RAM 202 only by checking the selection items displayed in the display field of the touch panel monitor 204. Therefore, it is possible to provide a testing machine with good operability without using a personal computer or the like.

  The case has been described above in which the USB memory 300 is set in the USB connector 205 of the control device 200 to record test result output data, and the USB memory 300 is set in a DPOF compatible printer and the test result is printed. However, if a network board is mounted on the control device 200 and the control device 200 is connected to the printer via a network, the DPOF data can be directly transmitted to the printer, and the test result as shown in FIG. 7 can be printed by the printer. Further, various portable recording media such as a memory card can be used instead of the USB memory.

  In the above description, the case of generating an image of a graph has been described. However, the present invention can also be applied to a case where a diagram other than a graph is generated as an image. Although the image data is stored in the DPOF format, a standard other than the DPOF file standard for printing an image generated on the testing machine side by connecting a digital camera and a printer may be used.

  Although the tensile tester has been described above, the present invention may be applied to a compression tester, a fatigue tester, a fracture impact tester, and the like. The present invention can also be applied to a material testing machine that uses a hydraulic actuator or a hydraulic ram as a load mechanism. Further, the type and type of the tester main body is not limited to the embodiment. In other words, the present invention is not limited to the above embodiment as long as the characteristics of the present invention are not impaired.
