Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation fan packaging device, and more particularly to a ventilation fan packaging device having a cushioning member for elastically fixing a ventilation fan body inside an outer box. .

[Prior Art] FIGS. 4 to 6 show a conventional ventilation fan packaging device disclosed in, for example, Japanese Utility Model Publication No. 57-20540, and FIG. 4 shows a cushioning member of the conventional ventilation fan packaging device. Fifth, showing perspective view
4 is a development view of the cushioning member of FIG. 4, and FIG. 6 is a plan view with a partial cross section showing a state in which the ventilation fan is stored in a conventional ventilation fan packaging device.

In the figure, 1 is a cushioning member made of a single plate-shaped member such as a corrugated board, 2 is a slit formed in the cushioning member 1 by die-cutting, and 3 and 4 are slits 2 and the cushioning member 1. The first outer side fold line and the second outer side fold line that connect to the edge portion are the first central part fold line and the second central part fold line that connect between the slits 2 formed on the left and right of the buffer members 1 and 5, respectively.
Reference numeral 7 denotes a bottom plate formed by vertically valley-folding the first outer side folding line 3 and the first center folding line 5 of the cushioning member 1, and 8 further vertically folds the second outer side folding line 4 to form the first outer side. The outer side plates formed between the partial folding line 3 and the second outer side folding line 4, and 9 are similarly mountain-folded at the second central portion folding line 6 vertically to form the first central portion folding line 5 and the second central portion folding line 5. Reference numeral 6 denotes a central side plate, and 10 denotes an upper plate formed between the second outer side folding line 4 and the second central folding line 6 and the left and right end edges of the cushioning member 1. 11
Is a ventilating fan main body, and includes an oil receiving portion 11a and a frame portion 11b. 12 is an outer box such as a cardboard box that houses the ventilation fan main body 11 and the cushioning member 1, 13 and 14 are inner flaps and outer flaps that serve as lids for the openings of the outer box 12, and 15 is the ventilation fan main body.
It is a protective plate that also acts as a spacer interposed between the oil receiving portion 11a of 11 and the outer box 12.

The conventional ventilation fan packaging device is configured as described above, and the ventilation fan main body 11 is elastically fixed in the outer box 12 by the cushioning member 1. The vertical and horizontal lengths of the cushioning member 1, the size and the position of the slit 2, the position of each fold line from the first outer side fold line 3 to the second center fold line 6, and the like are the outer shape of the ventilation fan main body 11. Also, it is appropriately set according to the inner size of the outer box 12. The cushioning member 1 is formed by bending a single plate-shaped body made of a cushioning material, has a small number of wasteful parts, and is easy to assemble.

This type of cushioning member 1 is used to prevent stains and damage during transportation of the ventilation fan main body 11, and in particular, the material cost and work cost are low and economical.

[Problems to be Solved by the Invention] The conventional ventilation fan packaging device as described above has the cushioning member 1
The dimensions in the vertical and horizontal directions after assembly were substantially the same as the dimensions in the outer box 12. Therefore, when the cushioning member 1 and the ventilation fan main body 11 were stored in the outer case 12, the cushioning member 1 could not be inserted into the opening of the outer case 12 unless the cushioning member 1 was completely assembled. By storing the cushioning member 1 in the outer box 12, the original shape of the cushioning member 1 was maintained.

However, since an elastic force that tries to return to the state before bending is applied to each folding line portion of the cushioning member 1, in the state of the single item before storing the cushioning member 1 in the outer box 12, the above-mentioned first It was difficult to maintain the shape of FIG. Therefore, the workability of packaging and assembling was poor, and there were many complaints on the packaging line.

Therefore, in the assembling work of the cushioning member 1, it is necessary to carefully perform the folding-back work of each folding line from the first outer side folding line 3 to the second center folding line 6. Further, since the cushioning member 1 and the ventilation fan main body 11 cannot be kept in an integrated state, automatic packaging such as automatic assembly cannot be performed. Therefore, the outer box of the cushioning member 1 and the ventilation fan main body 11
It took a lot of labor to store the inside of 12 and a lot of working time.

Also, since this type of cushioning member 1 has a single-plate structure, when packaging a particularly heavy ventilation fan body 11, an outer box 12 is used.
Could be deformed or the ventilation fan main body 11 might be damaged. For this reason, the cushioning effect is not sufficiently exerted, and the ventilation fan body 11 which is relatively heavy and the ventilation fan body 11 which is weak against vibrations.
Was not suitable for packaging.

On the other hand, as another prior art, there is a technique disclosed in Japanese Utility Model Publication No. 58-11748.

However, in this technique, two cushioning members each made of an independent plate-like cushioning material such as the corrugated cardboard described above are superposed, and the relative movement between the two is made freely possible, and the cushioning material can be stored in an outer box. Workability is not good. When an external force is applied in the left-right direction or the up-down direction when viewed from above, the movement in only the left-right direction or the up-down direction matches the bending direction, and the mechanical strength is not strong.

Therefore, the present invention can easily maintain the integrated state of the cushioning member and the ventilation fan main body, has good workability for storage in the outer box, and can sufficiently exhibit the cushioning action. Is the challenge.

[Means for Solving the Problem] A ventilation fan packaging device according to the present invention includes a cushioning member interposed between a ventilation fan main body and an outer box that accommodates the ventilation fan main body and elastically fixing the ventilation fan main body in the outer box. In the packaging device of the ventilation fan, the cushioning member includes a bottom plate formed by a plate-shaped body made of one cushioning material according to the outer dimensions of the ventilation fan main body and the inner dimension of the outer box, and bending from the bottom plate.

And an inner cushioning member 1b including an inner upper plate 26, and the outer cushioning member
1a and the internal cushioning member 1b are overlapped to form a double structure, and the cushioning member 1 is provided between the ventilation fan body 11 and the outer box 12 to elastically fix the ventilation fan body 11 in the outer box 12. It is a thing.

Therefore, the predetermined shape after bending can be maintained even in the state where the cushioning member 1 is a single product before being housed in the outer box 12. Therefore, it is not necessary to carefully perform the folding work of each folding line from the first outer side folding line 3 to the second center folding line 6 in the assembling work of the cushioning member 1 as in the prior art. Further, in this embodiment, since the buffer member 1 and the ventilation fan main body 11 can be fitted and kept in an integrated state, automatic packaging such as automatic assembly can be performed. As a result, it becomes easy to store the cushioning member 1 and the ventilation fan main body 11 in the outer box 12,
The work time can be shortened.

In addition, the outer cushioning member 1a and the inner cushioning member 1b of the cushioning member 1
By adopting the double structure of and, the cushioning effect is sufficiently exerted also on the ventilation fan main body 11 which is relatively heavy and the ventilation fan main body 11 which is weak against impact. Therefore, even when the heavy ventilation fan main body 11 is packaged as in the conventional case, the problem that the outer box 12 is deformed or the ventilation fan main body 11 is broken is solved, and it is suitable for packaging of the ventilation fan main body 11. It becomes a packaging device.

Moreover, in this embodiment, the outer cushioning member 1a and the inner cushioning member 1b are simultaneously manufactured by die-cutting a plate-shaped body made of one cushioning material, so that the manufacturing man-hour can be reduced and the number of raw material parts can be reduced. Is the same as the conventional one, and it is economical with little waste of raw materials.

In the above embodiment, the case where the ventilation fan main body 11 is housed in the outer box 12 by using the two cushioning members 1 has been described (see FIG. 3). Only one may be used.

[Effects of the Invention] As described above, the ventilation fan packaging device of the present invention is interposed between the ventilation fan main body and the outer box that houses the ventilation fan main body.
In a packaging device for a ventilation fan, which comprises a cushioning member for elastically fixing the ventilation fan main body in the outer box, the cushioning member is
A bottom plate formed by a plate-shaped body made of one cushioning material according to the outer dimensions of the ventilation fan main body and the inner dimensions of the outer box, and an outer side plate and a central side plate that are bent from the bottom plate and face each other. , The inner surface of the outer box and the outer part are formed so as to be in contact with the inner surface of the outer box from the outer part side plate and the central part side plate in parallel to the folding lines of the bent outer part side plate and central part side plate. An external cushioning member including a side plate and an upper plate that holds a space between the side plate and the central portion side plate, and a plate-shaped body that is the same as the external cushioning member. An inner upper plate coupled to the outer cushioning member, and inner plates that are bent and formed in a direction orthogonal to the folding line direction in which the outer cushioning member is bent in accordance with the inner size of the outer cushioning member and face each other,
The inner cushioning member is composed of a bottom plate of the outer cushioning member bent and formed in parallel with a fold line of the inner plate and an inner bottom plate having a double structure by overlapping with the bottom plate of the outer cushioning member.

Therefore, a double structure is formed by stacking the same plate-like body as the external cushioning member, which is bent in a certain direction in accordance with the internal size of the external cushioning member, with the bending direction orthogonal to that of the internal cushioning member. The cushioning member is interposed between the ventilation fan body and the outer box, and the ventilation fan body is elastically fixed in the outer box, so that the cushioning member can be stored in the outer box as a single item. Since the predetermined shape after bending can be maintained, the work of storing the cushioning member and the ventilation fan main body in the outer box becomes easy, and the work time can be shortened. Moreover,
Since the cushioning member has the double structure of the outer cushioning member and the inner cushioning member, the inner surface of the cushioning member constituted by the outer cushioning member and the inner cushioning member forms a surface, so that the contact area with the ventilation fan main body is large. Therefore, the ventilation fan main body can be protected regardless of the direction of the force applied, and the upper plate for holding a space between the outer side plate and the center side plate and the inner surface of the outer box is provided. Since it has a heavy structure, a space can be maintained by a space without stacking and filling a cushioning member between the ventilation fan main body and the outer box,
Furthermore, since the bottom plate that supports the weight of the ventilation fan main body has a double structure, it is possible to obtain sufficient strength by duplicating the parts that need strength, and to exert a sufficient cushioning effect, so that the weight of the The packaging device is also suitable for packaging certain ventilation fans and shock-sensitive ventilation fans. Since there is a space between the outer side plate and the center side plate, which are firmly held by the upper plate of the double structure, and the inner surface of the outer box, compared to the case where the cushioning members are stacked and filled. Since the amount of material used is small, the cost can be reduced, and the weight is also lightened, it is possible to obtain an effect that the burden on each of the stacked box bodies is reduced.
