After a ₁ is engaged and supported, the operation cylinder 21 at the upper end of the plates 8 and 9 is moved back, that is, moved upward.

As a result, the left and right side plates A are placed between the fixed piece 23 on the upper side and the movable piece 22 on the lower side, as shown in FIG.
Check as shown in Figure B (second step).

Next, the operation cylinder 11 on the outer side of the panels 8 and 9
When hydraulically driven, each shelf board B, B ₁ and architrave C
The handles b ₁ and c ₁ protruding from both ends of the side plate A and the handle a ₂ bored at a predetermined position on the side plate A are fitted and engaged as shown in FIG. 3 steps).

Next, the operation cylinder 21 at the upper end of the panels 8 and 9 is moved down, and the adapter 3 on the movable piece 22 is moved downward.
6 is removed, and the top plate D is mounted and supported on the movable piece 22 as shown in FIG. 12B (d) (fourth step).
Next, when the operating cylinder 21 is moved upward again, the handle a ₁ protruding from the lower end of the side plate A and the handle hole d ₁ bored at both left and right ends of the top plate D are opened as shown in FIG. 12b. Fit and engage as shown in Figure E (fifth step).

In addition, a back plate E such as a plywood board is fitted into the grooves a ₃ and d ₂ formed on the inner surface of the side plate A and the upper surface of the top plate D, and in this state, the upper edge of the side plate A, the upper edge of the architrave C, and Separately, a sliding plate F is nailed and fixed between the horizontal crosspiece _e1 at the upper end of the back plate E to complete the entire assembly process.

After assembling and configuring the box frame X having the joint structure shown in FIG. 12a in this manner, each operating cylinder 11, 21,
26 to return to its original position, thereby releasing this chucking and removing the box frame object X.
Take it out from the machine to the front (6th step).

In the case where the top plate D is configured to extend outward from the side plate A, a spacer having the thickness of the overhang width is adhered and fixed to the inner surfaces of the boards 8 and 9.

Next, FIGS. 7 to 1 show a second embodiment of the present invention.
