As shown in a cross section in FIG. 2, the claw piece 5 and the holding piece 6 are engaged by fitting the claw piece 5 between the holding pieces 6. It does not come off in the state of. This is because the claw piece 5 is formed in a slightly hook shape, and this is strongly pushed into the gap between the holding pieces 6 and is resiliently locked. When it is desired to open the storage box positively, when the second half member 3 is strongly separated from the first half member 2, the claw pieces 5 become slightly stretched, and at the same time, the gap between the holding pieces 6 slightly widens, Therefore, the claw pieces 5 and the holding pieces 6 are released.

In the present invention, the storage box 1 having the above configuration is initially in a closed state. The storage box 1 in a state where the two half members 2, 3 are closed is supplied to the apparatus of the present invention from another place. Here, as shown in FIG. 3, the unfolding device of the present invention presses the stopper 10 for supporting and fixing the first half member 2 at a fixed position on the receiving table and the hinge portion 4 of the fixed storage box 1.

The stopper 10 is formed, for example, in an L-shape, and is mounted so as to be rotatable around a support shaft 15 at an appropriate position on the support base 14 as shown by an arrow, as shown in FIG. A conveyor 19 for placing and transporting the storage box 1 is provided beside the cradle 14, and the conveyor 19 will be described later. The storage box 1 is, as described above,
In a state of being closed from another place, it is supplied to the cradle 14 via the chute portion 14a and placed. Oppression roller 11
Is, for example, a rubber roller having a suitable hardness and rotating, and is attached to the receiving base 14 via the arm 16 so as to be swingable around the support shaft 17 as shown by an arrow (see FIG. 4).

The opener claw 12 is formed, for example, in an L-shape, and is rotatably supported as shown by an arrow around a support shaft 18 at an appropriate position in the vicinity of the cradle 14 as shown in FIG. The tip of the opener claw 12 comes into contact with and engages with the inner surface of the edge of the first half member 2 (see FIG. 5A). In addition, it is preferable that a pair of the opener claws 12 are arranged side by side (in the direction perpendicular to the paper surface in the drawing) and abut on the inner surface of the edge at two places. Further, the opener claw 12 is configured to slide and move in the left-right direction as shown in the figure as indicated by an arrow, and to be able to catch the first half member 2 and move it onto the conveyor 19 [FIG. B)

As shown in FIG. 6, the above-mentioned conveyors 19 are arranged side by side at the extension of the receiving table 14 in the sliding direction of the storage box 1. This conveyor 19
Is running in the direction perpendicular to the paper surface, and the first of the storage boxes 1
The half member 2 and the second half member 3 are received from the cradle 14 and transported in a state where they are unfolded substantially horizontally.

The guide plate 13 is used to open the second half member 3 with respect to the first half member 2, and as shown in FIG. 6, at least the unfolded half members 2, 3
And has a clearance equal to or greater than the height (thickness), and is disposed at an upper fixed position while moving from the receiving table 14 to the conveyor 19. In addition, the guide plate 13 is provided on both sides 3A of the second half member 3.
It is preferable that a pair is arranged side by side so as to press against. If the end 13a of the guide plate 13 is formed in a tapered or tapered shape, the guide is smooth.

The above-described stopper 10 and pressure roller 11
The opener claw 12 is operated by well-known driving means (for example, a cam driving mechanism or a pneumatic cylinder or the like) not shown. The operation timings are controlled by a sequence control device (not shown).

Next, the process of unfolding the storage box 1 according to the present invention will be described. First, the storage box 1 is supplied to the cradle 14 from the chute portion 14a in a closed state. As shown in FIG. 3, the stopper 1 waiting at a predetermined position
When the edge 2A of the first half member 2 comes into contact with 0,
The storage box 1 is stopped and positioned and fixed. Thereafter, as shown in FIG. 4, the elastic pressure roller 11 swings against the positioned storage box 1 to elastically contact the hinge portion 4 and press it. The pressure roller 11 acts so as to ride on the corner region P of the hinge portion 4 while rotating on the storage box. The engaging portion of the storage box 1 is disengaged by the pressing force of the elastic pressure roller 11, and the second half member 3 is opened.

FIG. 7 shows the releasing action of the engaging portion by the elastic roller 11. The position where the elastic pressure roller 11 elastically contacts is near the center on the back side of the storage box 1 (see FIG. 7C). The second half member 3 is positioned on the receiving table 14 by the pressing of the elastic roller 11.
(See FIG. 7A). When further pressed, the claw piece 5 of the engaging portion and the holding piece 6 are disengaged (see FIG. 7B). Then, by further pressing, the second half member 3 opens greatly.

When the hinge portion 4 is pressed by the elastic pressure roller 11, the hinge portion 4 may be elastically contacted from the corner region (P) of the hinge portion 4 in FIG. By pressing this corner area (P) near the center part on the back side of the storage box, the second half member 3 is easily displaced as shown by the arrow, and the engagement between the claw piece 5 and the holding piece 6 is increased. Can be smoothly and reliably released. In addition, when the corner area (P) is pressed with a certain strength by the elastic pressure roller 11, not only the engaging portion is released, but also the corner of the corner area (P) is extended, and the recoil thereof causes The second half member 3 warps, and as a result, the second half member 3 opens largely with respect to the first half member 2.

In the closed state, both ends of the storage box 1 are flush with the edge 2A of the first half member 2, the edge 3A of the second half member 3, and the edge 4A of the hinge portion 4. Since they are provided so as to be in contact with each other, they are mutually deformed and hardly deformed by the force of the elastic pressure roller 11. As a result, only the vicinity of the center of the back side (hinge part 4) of the storage box 1, which is the pressing position of the elastic pressure roller 11, is largely deformed, so that the warping phenomenon is promoted.

FIG. 8 is a view showing the operation, and schematically shows a change in the open state of the half members 2 and 3 at the central portion on the back side of the storage box. Here, (A) is a side cross section of the center part on the back side of the storage box, and (B) is each (A)
It is a top view with respect to a state. The first state of (A) is a state in which the pressing roller 11 is in contact with the corner P1 of the storage box. The second state of FIG.
Reference numeral 1 denotes a state where the corner P1 of the storage box is pressed. The engaging portion of the storage box 1 is disengaged, and the second half member 3 opens with respect to the first half member 2.

In the third state of FIG.
Is a state where the corner P1 of the storage box is further pressed.
The opening of the second half member 3 is further greatly changed with respect to the first half member 2. As described above, the engagement portion of the storage box 1 is disengaged (released) by the action of the elastic pressure roller 11, and the opening S is formed between the first half member 2 and the second half member 3. It is formed.

Next, the opener claw 12 rotates as shown in FIG. 5, and is caught on the inner surface of the edge of the first half member 2 through the opened opening S. Then, the opener claw 12 holds the first half member 2 (the entire storage box) in a direction from the hinge portion to the engagement portion while the half member 2 is hooked,
That is, it is slid in the direction of the conveyor 19. When the first half member 2 is slid, when passing under the guide plate 13, the second half member 3 coupled to the first half member 2 moves integrally, and the guide plate 13 is moved.
It is forcibly pushed open and deployed.

FIG. 9 is a diagram showing the opening operation.
When the entire storage box slides in the direction of the conveyor 19, the guide plate 13 comes into contact with the edge 3A of the second half member 3 (see FIG. 9A). Then, the guide plate 13 pushes and opens the second half member 3 while abutting on the second half member 3 (see FIG. 9B). In other words, the second half member 3 falls down in the opening direction while pressing against the stopped and fixed guide plate 13.

Until the storage box 1 moves from the cradle 14 to above the conveyor 19, the second half member 3
However, it is gradually developed. When the opener claw 12 has pulled off the first half member 2, that is, when the storage box 1 has completely moved from the cradle 14 onto the conveyor 19, the two half members 2, 3 are substantially horizontal. (See FIG. 9C). And opener claw 1
2 slides back to its original position again. The developed storage box 1 is thereafter moved by the conveyor 19
It is further conveyed to the next step, and, for example, another member is assembled.

Although the present invention has been described above, the present invention is not limited to the embodiment, and it goes without saying that various other modifications are possible without departing from the essence of the present invention. For example, either the first half member or the second half member may be a lid.

The method of displacing the half member by the pressing of the elastic pressure roller to release the engaging portion is not limited as long as the engaging portion can be released by the positional deviation.
Any structure is applicable. In that sense, DVD
