DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for automatically covering a case body 1 having a side wall 1a with a cover 2 having a side wall 2a partially overlapping the side wall 1a.

[0002]

2. Description of the Related Art In automatically covering a case body having a side wall with a cover body having a side wall partially overlapping the side wall, the cover body is rotated with a chamfered portion of a corner bent portion of the case body as a fulcrum. There is such a technique. Further, as an apparatus for carrying out the method, fixing means for holding a case body with a chamfered corner bent portion at a predetermined position,
There is known a case in which a lid having a side wall overlapping the side wall portion of the case body and a lid holding means for rotating around a corner bent portion of the case body as a center (for example, Japanese Unexamined Patent Application Publication No. 05-147604).

[0003] In the prior art, the lid is put on the case body by rotating the lid. That is, with the case body fixed, the lid is rotated with the chamfered portion of the corner as a fulcrum.

[0004]

As described above, in the conventional method in which the lid is turned on the case body so as to cover the case body, the case body and the lid have a strong rigidity as in the case of a resin molded product. There will be no problem if it is made of something, but if it is made of something that is not strong like paper, both the case body and the lid may be deformed. Since there are many cases, simply turning the lid with respect to the case body cannot cover the lid reliably.

Further, the prior art employs a method in which only one of the two sides of the lid is held on the assumption that the case body and the lid are resin molded products. When the case body and the lid are resin molded products, it is sufficient to hold only one of the two sides of the lid, but when the case is made of something that is not strong like paper In this case, if only one of the two sides of the lid is held, the lid is easily deformed and cannot be covered with the case body.

[0006] In particular, when the case body and the lid are made of non-rigid materials as in the case of paper, and when they are used as pass-through boxes, after the product has been transported. out of the box, at least, the lid, as shown by the a, a of a ₀ and 3 in FIG. 2, b 1, bulky by bending a portion to be a side wall with a four peripheral parts thereof When folded into a sheet, a large number of them are stacked and carried, and reassembled for use, the four side walls are raised from the four peripheral portions as shown in FIG. 1 b, FIG. 2 b and FIG. 3 c, It is used again as a lid. Although not shown, the case main body is also of a so-called assembling type. After the product is transported, it is developed and folded into a non-bulky sheet shape, a large number of these are stacked and carried. As shown in FIG. 2C and FIG. 2C, four side walls are formed and used again as a case body.

As described above, in the case where the case body 1 and the lid 2 are made of a material that is not strong as in the case of paper, and when they are used as pass-through boxes, However, since at least the lid 2 has a so-called folding habit and it is difficult to keep the lid in a regular shape as shown in FIGS. 1B and 3C, the case body and the lid are made of synthetic resin. However, there is a problem that the lid 2 is hard to cover the case body 1 in particular. For example, the lid 2
It is difficult to hold the four side walls perpendicularly to the top plate 2c, and it is likely that the four side walls are bent inward. In this state, even if the lid body 2 is put on the case body 1, the side walls bent inwardly It cannot be covered well because it is caught on the four peripheral walls of the main body 1.

In the case where the case body 1 and the lid 2 are made of non-rigid materials as in the case of paper and the case body is used as a pass-through box, When the strength of the cover 1 is compared with the strength of the cover 2, an article (generally, almost always a product) must be put in the case body 1, and therefore, the cover 2 is usually used.
Although it is stronger in strength, it is sufficient to cover the case body 1 with the lid 2, so there is almost no problem even if the strength is weaker than the case body 1. Therefore, the cover 2 is usually weaker in strength than the case body 1 in many cases.
Is moved to cover the case body 1 with difficulty. If this method is adopted, the above-described problem occurs when the lid is covered.

According to the present invention, even in such a case, the cover 2 can be securely covered on the case main body 1. That is, the present invention relates to the side wall 2 of the lid 2.
a is engaged with the side wall 1 a of the case body 1, and then the case body 1 is moved upward, so that the case body 1
The cover 2 is put on the cover. Then, simply just beyond the relative movement between the lid and the case body, merely by moving the case body 1 with respect to this while holding the lid member 2 from both sides, to case body 1 The cover 2 can be securely covered
Things .

[0010]
