オーで強伸度を測定するようにしている。Generally, when measuring the strength and elongation of a sample using a yarn tension tester, in order to ensure the accuracy of the test length, a certain initial load is applied to the yarn to create a tensioned state with good straightness and convergence, and then further load is applied. I am trying to measure the degree of strength elongation by applying the force.

題があった。Conventionally, this work of adding the initial load was done manually↓, but since this work required the specimen to be attached to the pair of gripping tools of the testing machine without applying a load greater than the initial load on the specimen, it was A great deal of attention was required to prevent individual differences in tension, and as a result, there were many unstable factors such as reduced efficiency due to fatigue, and there were problems in obtaining quantitative test results.

Manually pull out the yarn from the yarn winding cheese 1 once,
Yarn guide 2, front clamp device 3, yarn guide 4b of upper air chuck 4, yarn guide 5b of lower chuck 5, ring 7c of initial load applying device 7, rear clap device 8, suction device! f 9 air nozzle 9a and yarn storage cap 7b
Thread the entire thread in this order. Here, the near nozzle 9a of the suction device 9
At the same time as f is activated, the front clamp filter, upper and lower air chucks 4.5 and rear clamp device t8 are opened, and the plunger of the air cylinder 7a is raised to remove the initial load tV. The yarn is suctioned into the reservoir 9b, but this causes the yarn to pass through the yarn tension tester from the winding cheese 1, which is the sample supply source, because the yarn between the reservoir and 9b is continuous. kl, the new and old will be replaced. Next, after a predetermined period of time, the air nozzle 9a is stopped by switching the 4-boat valve 101), and IIH force air is introduced to the front clamp 6 and the rear clamp 8, and a thread is created between the clamp face surface 31)/ and the fixed plate 3a/. It becomes a button when the row Y is gripped. Furthermore, after a certain period of time, the initial cart applying force device 7 is activated, and the ring 7C is lowered.
+) A load corresponding to the weight of the ring is applied, and tension is applied to the yarn Y. Furthermore, after a certain period of time has elapsed, the upper air chuck 4 and the lower air chuck 5 operate to grip the yarn Y. In this way, preparations for measuring the strength and elongation of the yarn are completed. After that, the toe chuck 5 is moved and pulled away from the identified upper chuck 4 to pull the yarn Yi, and the load cell 4
The strength of yarn Y is detected at C, and the measurement ends. Once this measurement is completed, reverse the above and move the front clamp 6.
The rear clamp 8 and the upper and lower air chucks 4.5 are released, and the air cylinder 7ajlr that applies an initial load is operated to raise the ring 7c'l, thereby eliminating the tension applied to the yarn Y. Next, when the near nozzle 9ai is operated, the yarn Y is suctioned and deposited in the storage basket 9b, and the yarn Y that was applied to the test machine is discharged, and a new yarn Y is pulled out from the winding cheese 1 and transferred to the K test machine. It will be supplied automatically.
