Third, the composition and working principle of the instrument
YG023C-III automatic single yarn strength machine is composed of three parts: main machine, printer and ordinary PC. See figure 1 for the appearance of the instrument.
The main engine adopts box structure, which contains Soc processing module, transmission mechanism, force measuring mechanism, length measuring encoder and driving circuit.
The transmission mechanism adopts imported DC servo driver and permanent magnet DC motor (with tachogenerator), and the output of motor shaft drives the chain through gear reducer. The chain is connected with the lower gripper, and the up-and-down movement of the lower gripper can be smoothly realized by controlling the motor to rotate forward and backward at a constant speed.
The rear end of the gear reducer of the instrument is connected with a high-precision encoder, and the output signal of the encoder is 0.05mm/ pulse. The elongation error is much less than ±1mm, which ensures the accuracy of length positioning and elongation measurement.
The driving circuit includes a sensor amplifying circuit and an input/output signal interface circuit. It mainly controls six electromagnetic air valves, manipulator drive, yarn carrier drive, button signal and limit switch signal.
Working principle is as follows:
Automatic test: firstly, set the test parameters and install the test samples. Press the "Start" button on the operation panel. The manipulator returns to the lowest position, the lower gripper rises to the top at the highest speed, and stops when it touches the upper limit switch. Clamping the sample, and then moving downward, when leaving the upper limit switch, it will be used as the starting point of length measurement. Sample the pulse number of encoder, and when the set clamping length is reached, the lower gripper stops. The manipulator clamps the sample and applies pretension, and the upper gripper pulls in. The lower gripper stretches at the set speed. The force sensor starts to be stressed. The computer samples the force value of the sensor and the elongation value of the encoder, and sends it to the screen for display and draws a strong elongation curve. After the first stretching, the computer processes the sampled data, and obtains the data such as breaking strength, breaking strength, breaking elongation, breaking work, breaking time, constant strength elongation and constant elongation strength. The broken residual yarn is automatically sucked by the yarn suction box. Then the instrument repeats the above process for the next test. When a tube test is finished, the leading yarn rack moves to the right by one grid, and the pneumatic scissors cut the last yarn. The manipulator goes up to the highest point and takes the next yarn for test. After the test is completed, the instrument stops working.
Manual test: when the sample is not suitable for automatic test, manual test can be selected. After setting the test parameters, press the "Start" button. The manipulator goes up to the highest position and stops when it touches the upper limit switch. And then run down to the clamping length. Take out the sample, put one end in the clamping surface of the upper gripper, press the "Start" button, and the upper gripper will pull in (if the yarn clamping is not good, press the "Stop" button to release the upper gripper, and then press the "Start" button to clamp the yarn again), put the other end of the yarn in the lower clamping surface, press the "Start" button to pull in the lower gripper, and the instrument will automatically carry out tensile test. Test data obtained after the completion of one test (same as data of automatic test mode). The lower gripper goes to the clamping length again for the next test. Data statistics are equivalent to automatic test.
IV,Description of Control Switch
"Power" switch: Turn on the instrument power when it is turned to the "ON" position, and turn off the instrument when it is turned to the "OFF" position.
"Start" button: Press this button to start the instrument when the lower gripper stops at the beginning of the test or during the test.
"Stop" button: when this button is pressed during the test, the gripper stops moving, and the test is invalid. Press "Start" to continue the test.
"Emergency stop" button: In case of any unexpected situation during the test, press the "Emergency stop" button to force the lower gripper to stop, and release the "Emergency stop" button to resume movement after the situation is eliminated. Note: During normal test, the emergency stop button must be in the released position, otherwise the test cannot be carried out.
V,Operation and use of instruments
This instrument is controlled by computer, so the operator is required to have common knowledge of computer operation.
First, start the computer, then turn on the main power switch of the instrument and power on the printer.

DeThe test interface is divided into four areas
Left test parameter area, middle curve box area, right strong elongation area and lower test result area.
Test parameter area: display the test parameters of the current group of tests,If you need to modify the test parameters, just enter the corresponding test parameters.
Note: It is forbidden to modify the test parameters when a group of tests are not completed,If you need to modify the test parameters, please click the "Stop" button to stop the test or press the stop button on the instrument. Then enter the parameters to be modified, click the New Test button, and then press Start to conduct a new set of tests.
Middle curve box area: shows the strength and elongation curves of each curve in the test. It can be set to display single curve and all curves,The software has automatic expansion function when displaying curves, that is, if the curve exceeds 90% of the coordinate frame during the test, the software will automatically increase the proportion of each grid of the coordinate frame so that the curve will not exceed the coordinate frame.
Note: When the mode of displaying all curves is selected, if there are many tests, there will be a corresponding delay when the curve box is automatically scaled. At this time, the software is redrawing all the test curves that have been done in this group of tests according to the scaled coordinate scale. Please be patient. The waiting time increases with the increase of test times.
Right strength elongation area: display the real-time data of a test, and display the breaking strength and after the completion of a test
Elongation at break.
Lower test result area: this area is divided into two layers, and the test results and statistical results are controlled and displayed by corresponding buttons. Test results show the results of each test. The statistical results show that up to this test, the statistical values of this group of tests include average value, maximum value, minimum value, mean square deviation and CV value.
