(Thus, the box body t placed on the first movable table 30
The AlO side edges can be positioned.

Further, on the side of the other stop position of the moving table 20,
As shown in FIG. 3, a fixed table 40 is arranged. This fixed table 40 is supported at approximately the same height as the upper surface of the movable table 20 at the raised position 1 as shown in FIG. The member 41 is the cylinder 4
It is connected to the piston rod 43 of No. 2 and can be moved up and down.
When raised, it protrudes above the upper surface of the fixed table 40 so that the front side of the box body GA') placed on the fixed table 4o can be positioned. The box body (A) positioned by the positioning member 41 is suction-supported by a plurality of suction ports 44 provided on the fixed table 40.

A second movable table 50 is arranged on the side of the fixed table 4o, as shown in FIG.

As shown in FIG. 6, this second movable table 50 is supported at the same height with respect to the fixed table 4o, and its lower surface (the ends of the plurality of arms 51 provided thereon are connected to the fixed table 4o).
The end of the arm 51 extends toward the support shaft 5.
It is rotatably supported by 2. Also, arm 5
1 is the piston rod 5 of the table rotation cylinder 53
4 is connected and the cylinder 53 is actuated, the second movable table 50 moves upward approximately 9 degrees centering on the support shaft 52.
Rotates 0°.

Further, the second movable table 50 has a plurality of positioning holes 55.
are provided at equal intervals in the moving direction of the moving table 20, and a positioning member 56 is detachably attached to the positioning hole 55 (see FIG. 1).

This second movable table 50 and the fixed table 40
As shown in FIG. 3 and FIG. When you rotate the guide shaft 57, it moves.

The movement path of the movable table 20 includes a stopper plate 60 (see FIG. 1) that prevents the rotation of the first movable table 30 (and thus the box body A assembled on the movable table 20) from falling down. , a guide 61 (see FIG. 10) that guides the movement of the box body tA) on the movable table 20 when the movable table 20 is moved, and a box body (A) transported to the other stop position of the movable table 2o. and the box body assembled on the fixed table 40 (
A') stopper plate 62 (first
(see Figure 0) are provided respectively.

Also, in the middle of the conveyance path of the moving table 2o, there are a joint piece (td) of the box body (A) and a joint piece (dl) of the box body (A) conveyed by the moving table 20.
Application nozzles 63 for applying adhesive to each portion of the tab plate [b) to be pasted are provided as shown by chain lines in FIG. 10.

Further, as shown in FIGS. 2 and 10, a presser plate 70 is disposed at an upper position between the other stop position of the movable table 20 and the fixed table 40, and the presser plate 7o is attached to the piston rod 72 of the cylinder 71. When connected, the movable table 20 and fixed table 4 can be moved up and down.
The top surface of the box body tA) and (A) above 0 are to be pressed at the same time.

The connection device shown in the embodiment has the above-described structure. After placing the main body (Al, tA+), mechanically assemble the box main body LAI ( That's what I do.

Figure 13 shows the box body (A), ^1 placed on the box body, with the joint piece facing downward and the lower tab plate (b
') is placed on the upper surface of the movable table 2o and the first movable table 30 so as to be supported by the movable table 2o, and is positioned by the positioning member 24 of the movable table 20 and the protruding shaft 36 of the first movable table 30. (3rd
(see Figures and Figure 4).

Further, the box body (A') is placed on the upper surface of the fixed table 4o and the second movable table 50 so that the joint piece (with dl facing upward and the lower tab plate tb) is supported by the fixed table 40. and is positioned by the positioning member 41 provided to be movable up and down and the positioning member 56 of the second movable table 50 (see FIGS. 3 and 6).

When (A) is set in the pair of box bodies as described above, the suction port 25 provided on the movable table 20 and the suction port 44 provided on the fixed table 40 are connected to the upper tab plate (b).
'), tbl is attracted, and after the attraction, the first movable table 30 and the second movable table 50 rotate upward about the support shaft 32.52.

As the first movable table 30 is rotated upward, its upper side plate (a) is raised, as shown in FIG.
The box body (A) is assembled into a rectangular tube shape on the moving table 20, with the joint piece td) protruding.

Moreover, by the upward rotation of the second movable table 50,
Since the upper side plate (a) is raised, the box body (AI is assembled into a rectangular cylinder shape on the fixed table 40 with the joint piece (d) protruding), as shown by the chain line in FIG. Figure 14 shows the assembled state.

In addition, in order to facilitate assembly into the box body (Al,
As shown in FIGS. 3, 8, and 9, push-up temporary plates 80 and 81 are arranged on one side of the moving table 20 and on one side of the positioning member 41, respectively, and each push-up plate 80
．． The piston rod 83 of the cylinder 82 is connected to the piston rod 81 so as to be able to move up and down, and the uplifting plate 80.81 is raised from between the pair of flaps tq and tc1 located on the lower side to the upper side plate ta'+ta+. It is preferable to push up the part.

When the pair of box bodies tA) and 〆) are assembled as described above, the movable table 2o moves to the left in FIG. It is applied to the upper surface of the joint piece (d) and one side of the upper surface of the upper knob plate tbl (to the box body).

At this time, the positioning member 41 is held at the lowered position, as shown in FIG. 10, and does not inhibit the movement of the movable table 20.

The moving table 20 stops when it moves to a position where the inside of the upper box body abuts against the stopper plate 62. FIG. 10 and FIG. 15 show the stopped state, and FIG.
Ie) shown in the figure is an adhesive layer.

After the movable table 20 has stopped, the table lifting cylinder 2
2, the moving table 20 is raised diagonally upward as shown in FIG. Due to the rise, the box body tA) on the moving table 20 comes into contact with the box body 1 on the fixed table 40, and the box body tA), the joint pieces 1d), [d) of the other box body (A), Fourth Tsuma Board tb
), (b), and after the moving table 20 stops rising, the presser plate 70 descends and presses the upper surfaces of the pair of parallelly arranged box bodies tA), ().

Therefore, each joint piece (d) can be adhered to the corresponding tab plate tbl, (b) to form a joint box IXI as shown in FIG. 16 (FIG. 16).

After the joint box is formed, the presser plate 70 is raised, and the first movable table 30 and the second movable table 50 are rotated from a vertically standing state and return to a horizontal state. Also,
The suction of the suction port 25.44 is released, the joint box tX) is removed, and the moving table 20 is moved backward to return to the state shown in FIG. 3.

In the case of the example, adhesive was applied to the upper surfaces of the joint piece td) and the tab plate tb) when moving inside the box body assembled into a rectangular cylindrical shape, but when the box body tA+ stopped, the adhesive was applied. The agent may be applied to the desired location.

Alternatively, the adhesive may be applied to the other box body. [Effect] As described above, according to the present invention, the orientation of the flat box body is regulated on the two table tops. Since the assembly of each box body and the connection after assembly can be performed automatically by a simple operation of placing the boxes on the boxes, joint boxes can be manufactured extremely efficiently.
