Ⅲ. Structure of Product and Operation Principle
Model YG023A Full Automatic Single Yarn Strength Tester consists of mainframe, printer, yarn holder and monitor. The appearance of the tester can be seen on Figure1 on Page9.
Transmission system adopts import direct current servo driver and mag-dynamo, the axle of the electrical machinery outputs and drives the chain through the gear wheel gearbox. Connect the holder on the roller chain, through control motor at the uniform up down to transfer to can realize going to the upper and lower sports of the lower gripper smoothly.
Dynamometry adopts the pole system of block of four. Upper gripper through hang board pressed against the sensor probe, the back is equipped with the counterweight and damper. The counterweight can play a balance role to the pole system of block of four. The output signal interface circuit. Mainly controlling six electromagnetic pneumatic valves, manipulator tramper can make the pole system of block of four don’t shake in the course of sport, that guaranteed the accuracy of dynamometry.
The back of instrument gear deceleration box links the high-accuracy encoder, the encoder outputs the signal as 0.05mm / pulse. Smaller than the error of elongation of ± 1mm, guaranteed that the length localized and elongation the accuracy measured.
Drive circuit including sensor amplifying circuit, input/output interface module, the yarn guider transmission, the signal of limit switch and signal of button switch.
Operation principle as follows:

Test automatically: Install the sample as per operation style and make changes of data of this test as per prompts on the menu in the monitor. After completion of change, press “S” key under test state and the lower gripper rises up at the highest speed to the top, grips the sample and moves down. When it leaves the upper limit switch, which will be referred as the origin of the coordinate to measure the length, the number of pulses from the grating will be sampled. When it arrives at the preset gripping distance, the lower gripper stops and the manipulator will exert force upon gripped sample. The lower gripper then draws with preset equal speed and the force sensor will be exerted by force. During the process the sample is drawn straightly till to be broken, the computer takes sample of value of the force sensor and number of pulsed to measure length continuously, and measure the time from the sample is drawing to it is broken. After completion of one drawing, the computer will deal with sampled data, and measure seven items of data covering breaking force, elongation and its rate, strength, power, time and strength-elongation curve, which will be displayed on the monitor and printed out by the printer. The suction box will suck the remaining broken yarn automatically. Then the lower gripper rises again to repeat above process to make next drawing test. When test times reach at the times preset for each tube, the front yarn guider moves one position to the right and the electrical scissor cuts the sample of last tube. The manipulator moves up to the position between two rows of buckle to grip the next sample and turns down to the position to make the test of the second tube continuously. After completion of all tests of preset numbers of tubes, the printer will print out the maximum, minimum, CV average values and strength-elongation curve as well.
Test manually: When the sample is unsuitable to test automatically, can choose the manual experimental way. After establishing the experimental parameter, push “start” button. Manipulator raises up to the highest, touch the upper limit switch stop. Then lowers down at the preset gripping distance. Take out sample in the upper gripper, then push “start” button, upper gripper shut to suck (if yarn grasp unkind, can push “stop” button to unclamp the upper gripper, then push “start” button to grip the yarn again), to grip the another end of sample yarn in the lower gripper, push “start” button sucks and makes the lower gripper jointly, The instrument carries on the draw test automatically after stopping for one second. Test data drawn after being finished in a test (same as automatic experimental way). The lower gripper rises up to present gripper distance and starts the next test. The data same as test automatically.

Ⅳ. Control Switches Instructions
“Power” Button: Press “on” key to turn on power supplies, press “off” key to turn on power supplies.
“Start” Button: This button that started the instrument to test.
“Stop” Button: Press it down to make the motor stop, this time test has failed. Press “Start” key to go on.
Ⅴ. Operation and Use of Instrument
The Instrument control by computer, computer operate must have general knowledge about computer.

At first, turn on power button of the main frame, wait for the computer to start WindowsXP to finish. Turn on the power button of printer. Whether mouse right key of mouse double click “YG023B” icon, enter and test procedure display as follows:

Operation Manual

The experimental parameter explained: (Note: The parameter is established and kept automatically well, namely the open parameter of next time is the amended parameter of last time)

Count/Pack: Input the times of per tube, the times are multiplied by tubes not being greater than 300.
Specified force: For determining and appointing the Length of the force place, establish it as zero when doesn’t need to test. Fixed force can't be greater than the range of sensor chosen.
Specified Length: For determining the force of appointing to Length place, establish
Ⅵ. Maintenance of Product
1. The average force of samples should be used within 80cN to 4500cN.
2. Make calibration of force display value once a year according to calibration regulations of the National Metrological Standard JJG475 “Electronic Universal Tester” for Class 1 tester so as to ensure accuracy of tests of the instrument.
3. Normally change ribbon of the printer once a year.
4. The positions of upper and lower limit switches inside the door at right side should not be loosened arbitrarily.
5. Maintenance of the air compressor can be seen on the operating instruction of the air compressor.
6. The layman can't dismantle the spare part-containing instrument at will.

Ⅶ. Common Trouble Clearing
1. The display trouble is explained:
1.1 “Manipulator does not reply get minimum location, please check manipulator transmission part and upper limit switch”
Manipulator have not touched the upper limit switch while it moves down, open the left side door to look over the signal lamp of manipulator at this moment, whether the fourth light is on from left, if shows that the manipulator moves down are normal. Use hands to be slight towards the left end of the pop-up manipulator again, if the machine can work, prove that there is appearance of skidding in the transmission part of the manipulator, check the transmission part of the manipulator. If can't work yet, please check two fuses on the drive board and upper limit switch circuit.
1.2 “Yarn guider doesn’t go to location in the course of changing yarn, please check according to the manual”
Open the left side door of the instrument and look over the signal lamp of manipulator, it is bright from the second light of left, if on, it means yarn guider operate normally, can push the yarn guider, if it can work normally after putting in place, check the transmission belt wears and tears the situation to need changing or not, and the rail of the beam bar of the yarn guider is leveled. Can adjust the upper and lower positions of both sides of beam bar.
1.3 “Receive the signal of lower limit in the drawing course, please check the lower limit or sample to extend too long according to the manual”
Confirm the elongation of exceeding the length that the instrument tests of the sample at first. If exceeding, can alter the length of gripper and carry on the test. Check the lower limit switch is damaged or not, and the circuit is normal or not.
2 Lower gripper can’t the yarn
Check the guide yarn position of front yarn guider is correct or not at first, lower gripper close normal or not. Yarn though front yarn guider, passes insert surface of upper gripper and gets the insert surface of lower gripper should keep the same to hang down on the line to reach. It makes mistakes which seats if have, can adjust properly.
3 After start the instrument, the lower gripper can’t move
Check “Stop Urgently” button is in unclamping the position or not.
Look over the D.C servo-driver in the adjustable-speed box that shows it should be “0”.
Check the plug of adjustable-speed box to insert in the socket to keep in touch well or not.
