Then, the first film 31 is placed so as to straddle the rod-shaped film support portions 42 and 42 arranged in a pair so as to sandwich the base portion 41 (cell main body 33) and one end of the cell main body 33. Thereby, the 1st film 31 is arrange | positioned so that the end of the cell main body 33 may be covered. In this embodiment, the film support portions 42 and 42 are formed in a substantially U shape by bending a round bar, but may be formed in a plate shape or a cylindrical shape. Also good.

  Thereafter, the cell main body 33 is passed through the film temporary fixing member 5 formed in an annular shape together with the first film 31. Accordingly, as shown in FIG. 5B, the first film 31 temporarily fixes the first film 31 on the lower side of the cell body 33 so that the first film 31 has one end and the outer periphery of the cell body 33. Arranged along the surface. At this time, since the first film 31 was placed in a stable state by the film support portions 42, 42, the wrinkles of the first film 31 generated by deformation are uniform.

  When the annular protrusion 61 provided inside the cylindrical pushing member 6 is inserted into the cell body 33, the first film 31 is moved by the annular protrusion 61 as shown in FIG. It is pushed into the inside of 33 and deforms into a concave shape. In addition, the first film 31 is deformed into a concavo-convex shape inside the cell main body 33 by the convex portion 43 protruding from the base portion 41 of the cell holding member 4.

Then, by holding the cell 3 with the holding unit 11, the sample S flows down into the container 131 through the opening formed in the second film 32 and the guide unit 132 (as indicated by the arrow E). Therefore, it is separated from the films 31 and 32 naturally.

  Then, as shown in FIG. 10A, the detaching member 15 is urged downward while the projection 152 of the detaching member 15 is in contact with the flange 342 of the film fixing body 34. Accordingly, as shown in FIG. 10B, the engagement between the engaging portion 331 of the cell main body 33 and the engaging portion 341 of the film fixing body 34 is released, and the film fixing body 34 moves downward. At this time, one end (lower end) of the film fixing body 34 is positioned below the one end (lower end) of the cell body 33.

  Then, as shown in FIG. 11A, after removing the lid member 16, the cell body 33 is removed from the film fixing body 34. Furthermore, after removing each film 31 and 32, as shown in FIG.11 (b), the cell 3 is disassembled by removing the removal member 15 and the film fixing body 34 in order.

  As described above, when the cell disassembly device 1 according to the present embodiment holds the cell 3 in the state in which the second film 32 is directed downward by the holding portion 11, the second film 32 is used by the blade portion 121 of the blade member 12. Disconnect. And since the sample S flows down from the opening of the 2nd film 32 formed by cut | disconnecting, the sample receiving part 13 arrange | positioned below the blade part 121 receives the sample S. FIG. Thereby, since the holding | maintenance part 11 hold | maintains the cell 3, the sample S can be discharged | emitted naturally from the cell 3, Therefore The operation | work which disassembles the cell 3 can be simplified.

Thereby, since it can prevent that the cell 3 shifts | deviates, the sample S can be reliably received by the sample receiving part 13. FIG.

  Further, in the cell disassembling apparatus 1 according to the present embodiment, since the blade portion 121 has an end and is formed in a bent shape (curved shape), the cut piece 321 of the second film 32 is directed downward by gravity. Droop. Therefore, since the opening for flowing down the sample S can be formed in the film, the sample S can surely flow down from the opening of the second film 32. Moreover, since the cut piece 321 is not separated from the second film 32, it is possible to prevent a part of the second film 32 (cut piece 321) from being mixed into the sample S that has flowed down.

  In addition, the cell apparatus 1 according to the present embodiment can separate the sample S from the cell 3 while holding the cell 3 by the holding unit 11, and further, the cell main body while holding the cell 3 by the holding unit 11 The engagement between the film 33 and the film fixing body 34 can be released. Therefore, since the sample S can be separated from the cell 3 and the cell 3 can be disassembled continuously, it is possible to simplify the processing operation after the analysis.
