Japanese Laid-Open Patent Publication No. 2009-25857 (Patent Document 7) discloses that a stretched sample is obtained by stretching a film sheet before stretching in a one-axis direction by a tensile tester. A two-axis extension tester in which a sheet-like sample is extended to a two-axis is disclosed using a link constituting a scaling mechanism, as disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. Japanese Laid-Open Patent Publication No. 2004-148878 (Patent Document 9) discloses a test device for extending a sheet material, comprising: a link device, a longitudinal extension means, and a lateral extension means, further comprising a longitudinal extension means and Control means for controlling the change time by the lateral extension means. However, according to the physical property evaluation of the film sample extended by the extension test apparatus disclosed in Patent Documents 7 to 9, the extension machine disclosed in Patent Documents 1 to 6 and In the case where the film is continuously produced by the biaxially stretched film manufacturing apparatus of the stretching method, the difference in the structure of the stretching test device and each of the stretching machines and the behavior at the time of extension may result in failure to obtain the same physical properties as the film sample. The case of the film. In the tensile tester disclosed in Patent Document 7, and the biaxial stretching tester disclosed in Patent Document 8, the test piece of the raw material roll sheet or the test piece of the raw material roll film is extended in a stationary state, It is difficult to say that it is an elongation test equivalent to the continuous production state by the stretcher of the biaxially stretched film manufacturing apparatus. Further, in the test device for extension disclosed in Patent Document 9, by the opening of the equal length link of the link device of 201202005, the one end portion of the pair of rails which are arranged gradually from the end toward the other end is used to hold the gripping device. The extension test was carried out to achieve the same conditions as those of the continuous production state of the stretcher of the biaxially stretched film manufacturing apparatus. However, in the test device for extension, only the tip holding device reaches the other end portion, and only the tip end of the sheet held by it is extended. Further, since the tip end of the sheet is a cut end, it has a characteristic different from that of the continuous film. In other words, even in the test apparatus for elongation disclosed in Patent Document 9, it is difficult to say that it is an elongation test under the same conditions as the continuous production state of the film in the stretcher of the biaxially stretched film production apparatus. In particular, in the curved portion of the rail of the extension machine, as disclosed in Patent Document 3, although the interval between the adjacent clips is changed, in the extension test device disclosed in Patent Document 9, the bending is performed. The move in the ministry was not considered. Further, with respect to the method of extending the film or sheet disclosed in Patent Document 5 and Patent Document 6, the corresponding elongation test cannot be performed. SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object thereof is to provide a test piece stretching device and a test piece extending method capable of performing conditions equivalent to continuous production of a film by an extension machine of a biaxially stretched film manufacturing apparatus. In the elongation test, a film sample showing the same characteristics as a film continuously produced by an extension machine can be obtained. The present invention is a test piece extension device having: being disposed on a rail

The second support device 21 pulls the second support device 14 disposed at the start point S2 until the end point E2, and causes the second support device 14 to be guided toward the second track 12 and the second pitch adjustment track 26. . Thereby, the second clip group 18 travels along the second rail 12. According to the present embodiment as described above, the elongation test can be carried out under the same conditions as the continuous production state by the link type simultaneous biaxial stretching machine which simultaneously stretches the raw material roll sheet or the material roll film in two directions. Namely, a film sample which is identical to a film which is continuously produced by a link type simultaneous biaxial stretching machine can be obtained. The specific procedure for the extension test performed by the test piece stretching device 1 is as follows. First, the orbits of the first orbital track 1 1 and the second track 12 are determined based on the elongation test conditions such as the stretch ratio in the flow direction of the test piece 15 and the stretch ratio in the width direction, and the track is formed (moved). 1 track 〗 1 and 2nd track 12.

Further, between the start point S1 and the start point S2 and between the end point E1 and the end point E2, an extension section B in which the test piece 15 is simultaneously extended in both the width direction and the flow direction is set. Specifically, in order to apply the extension in the width direction, the interval Dp is enlarged, and the interval L 1 p and the interval L2p are narrowed by applying the extension of the flow direction by expanding the clip pitch. Further, the upstream side of the extension section B is The preheating section A is set, and the heat treatment section C is set on the downstream side of the extension section 。. As described above, after the first rail 11 and the second rail 12, the first pitch setting rail 25, and the second pitch setting rail 27 are provided (arranged) in accordance with the extension test conditions, one edge of the test piece 15 is held and placed. The first clip group 17 at the start point S1 of the first track 11 holds the other edge of the test piece 15 at the second clip group 19 disposed at the start point S2 of the second track 12. Then, the first drive unit 20 and the second drive unit 21 are actuated, and the first support unit 13 and the second support unit 14 are pulled. As a result, the first clip group 17 and the second clip group 19 held by the test piece 15 travel along the first rail 1 1 and the second rail 12, respectively, and enter the preheating section A. And, stop here at this time. In the preheating section A, the test piece 15 is heated to a predetermined preheating temperature by the heating means 2 2a. After the warm-up of the test piece 15 in the preheating section A is completed, the first driving device 20 and the second driving device 21 are again actuated. Thereby, the first clip group 17 and the second clip group 19 held by the test piece 15 are each along the first track.

At this time, the test piece 15 is extended in the width direction as the interval Dp is enlarged. At the same time, as the clip pitch which is reduced corresponding to the interval L 1 p and the interval L2p is enlarged, it is also extended in the flow direction. Here, the entire first clip group 17 and the second clip group 19 held by the test piece 15 are extended by the extending section B so that the entire test piece 15 is extended in the width direction and the flow direction. Then, after extending the section B, the first clip group 17 and the second clip group 19 enter the heat treatment section C, and are stopped at this time. In the heat treatment zone C, the film sample 23 which is formed by stretching the test piece 15 is heated to a predetermined heat treatment temperature by the heating means 22c. Thereby, its physical properties are stabilized. After the heat treatment of the sample film 23 in the heat treatment section C is completed, the first drive unit 20 and the second drive unit 21 are again actuated. Thereby, the first clip group 17 and the second clip group 19 held by the sample film 23 are respectively reached to the end point E1 and the end point E2. Thereafter, the sample film 23 held by the first clip group 17 and the second clip group 19 is taken out. After the sample film 23 is taken out, the first support device 13 including the first clip group 17 and the second support device 14 4 including the second clip group 19 are respectively selected from the end point E丨 and the end point E2 for the next extension test. It is taken off and installed again at the start point S1 and the start point S2. However, the movement from the end point E1 and the end point E2 of the first support device 13 and the second support device 14 to the start point S1 and the start point S2 may be performed by providing the traction device at the start point S1 and the start point S2 side. That is, the first drive unit 20 and the second drive unit 21 respectively set the i-th support unit 13 and the second branch -17-201202005 support unit 14 between the start point S1 and the start point S2 and the end point El and the end point E2. It can also be configured to reciprocate. According to the present embodiment as described above, the first clip group 17 and the second clip group 19 held by the test piece 15 are directed from the start point S1 and the start point S2 of the first track 11 and the second track 12 toward the end point E1. And the end point E2 walks. Further, when the test piece 15 is entirely extended by the extension section B set in the running section, the film sample 23 can be obtained. At least the central portion of the test piece 15 is continuous (because it is not the cut end), so that the obtained film sample 23 can be said to have the same physical properties as those continuously produced by the biaxially stretched film manufacturing apparatus. Further, in order to carry out the extension test by using the link type simultaneous biaxial stretching machine itself, it is necessary for the pair of endless (annular) rails formed by the rail and the sprocket to be continuous and endless (annular) like the transmission link member. A plurality of linked clips continuously walk. In this test, the size of the first clip group 17 and the second clip group 19 held by the test piece 15 in this embodiment are large and the efficiency is also different. Since the start point S1 and the start point S2 of the first rail 11 and the second rail 12 which are arranged are arranged toward the end point E1 and the end point E2, the extension test can be performed efficiently. In the present embodiment, the first rail 11 and the second rail 12 are arranged symmetrically with respect to the center line CL, but may be appropriately selected depending on the elongation test conditions of the test piece 15, and may be adapted according to the extension test conditions.
