Description

[Detailed description of the invention] The present invention relates to a packaging device for ventilation fans that is equipped with a buffer that is interposed between the outer box and the ventilation fan to fix the ventilation fan inside the outer box when the ventilation fan is packed in the outer box. .

Conventionally, in packaging equipment for household electrical appliances, especially ventilation fans, a cushioning body is interposed between the outer box and the ventilation fan in order to prevent damage caused by movement of the ventilation fan stored in the outer box during transportation. That's what I do.

Conventionally, such shock absorbers have been made of foamed resin molded products or corrugated cardboard sheets cut into appropriate dimensions, assembled, and bonded to form a predetermined shape.

However, with such conventional cushioning materials made of foamed resin, it is difficult to dispose of or incinerate after use from the perspective of preventing pollution, and with corrugated cardboard sheets, cutting and gluing the sheet materials is troublesome. It has drawbacks such as not being easy to manufacture and the manufacturing cost being relatively high.

Therefore, in view of the above-mentioned conventional circumstances, the present invention has been developed by constructing a first buffer body made of a paper sheet material. The structure is such that the second shock absorber is assembled, and this sheet material is simultaneously die-cut from a single sheet material, and the first shock absorber is assembled. To provide a packaging device for a ventilation fan that solves the above-mentioned drawbacks and is easy to dispose of waste material and easy to manufacture by forming the second buffer body into an integral structure by folding sheet materials. It is.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is a packaging device according to the present invention,
This is a rectangular corrugated cardboard sheet material that constitutes a first buffer body A that accommodates and supports a ventilation fan, and a second buffer body B that is fitted over the top of the ventilation fan.

The first buffer body A is connected to a first half sheet 2A through a fold described later provided at the longitudinal intermediate portion of the sheet 1 to the material 1.
and a second half sheet 2B which is integrally and simultaneously die-cut as a sheet material 3 whose intermediate portion is approximately rectangular for the second buffer body B. In the sheet material 2, broken lines 2a to 2C are folds to be folded inwards at right angles, dashed-dot lines 2d to 2f are folds to be folded outward at right angles, and dashed-two dotted lines 2g are folds to be folded outward to the right half of the sheet material 2.

In the first half-sea)-2A, 5 is a bottom plate in the center, and 6 and 7 are side plates extending from the bottom plate 5 through folds 2 a and 2 b, respectively, in the left and right end directions in the figure. , 10
and 11 are plane flaps that are connected to these side plates 6 and 7 via folds 2d and 2e; 12 is a notch that separates the central part of the side plates 6 and 7 from both ends thereof and a part of the plane flap 10.11; 13A is a U-shaped notch formed at the fold 2d portion of the plane flap 10.11 with the side plate 6.7, and by bending this portion outward, a notch 13 for connecting the second buffer body B, which will be described later, is formed. becomes.

The second half-sheet 2B is formed by bending along the folds 2C, 2f, 2g, and contacts the bottom plate 5 and the lower surface of both hand flaps 10.11 of the first half-sheet 2A. The first half-sea) 2A is reinforced.

Reference numeral 18 denotes a notch groove formed at the inner end of the second half-sea (2A), which corresponds to the connecting notch groove 13.

Such first and second semi-sea) 2A, 2B
An assembled diagram of the shock absorber A is shown in FIG. 2.

That is, in FIGS. 1 and 2, the side plates 6 and 7 are aligned at fold line 2.
At the same time, the planar flaps 10 and 11 are respectively bent at a right angle to the outside through fold lines 2e, and the side plates 6 and 7 are made to face each other via the bottom plate 5. Planar flaps 10.11 extend horizontally from the upper ends of the side plates 6,7.

In this case, the side plates 6 and 7 are formed in a stepped shape in which the distance between the two end portions is smaller than that between the center portions, and this stepped portion serves as one transmission surface.

Next, the second half sheet 2B, which has been bent into a predetermined shape along the folds 2C and 2f, is bent by 180 degrees through the fold 2g and adhered to the bottom surface of the bottom plate 5 and the side plane flaps 10 and 11.

In this case, the second half-sea) 2B faces both ends of the side plates 6 and 7 with a gap between them.

On the other hand, in the substantially rectangular sheet material 3 constituting the second buffer body B, 20 is a top plate in the center, and 21 is connected from the top plate 20 toward both side ends via folds 3a.

Reference numeral 22 denotes a connecting flap 22 which is cut and raised during assembly by a U-shaped notch 3b connected to the fold 3a of the top plate 20;
A is a connecting insertion piece formed at the tip of the connecting flap 22, and is inserted into the cut groove 13 of the first buffer body A during assembly.

The assembly diagram of the second buffer body B made of such sheet material 3 is shown in the third figure.
As shown in the figure.

That is, in FIGS. 1 and 3, the side plates 21 are each folded inward at right angles through the folds 3a, and the connecting flaps 22 are cut and raised flush with the side plates 21 from the notches 3b.

The procedure for packaging a ventilation fan using the packaging device for ventilation fans that separates the first and second buffer bodies A and B having such a configuration will be explained based on FIGS. 2 and 4.

First, the frame 23A of the ventilation fan 23 is inserted into the upper space of the bottom plate 5 of the first shock absorber A as shown in FIG. 23A is placed with the bottom surface raised above the bottom plate 5.

In this state, the side plates 6, 7 and 8, 9 are in contact with and fixed to the frame 23A of the ventilation fan 23.

Next, cover the second buffer body B from above and insert the insertion pieces 22A at the lower end of the side plate 21 into the cut grooves 13 of the flat flaps 10.11 of the first buffer body A, and then Unify bodies A and B.

In this state, the oil pan 23B of the ventilation fan 23 is clamped and fixed between the second buffer B and the flat flap 10.11.

Then, the ventilation fan 23 supported by the first and second shock absorbers A and B is inserted into the outer box 24, and the outer box 24 is sealed with tape, etc., to complete the packaging.

In this configuration, the ventilation fan 23 is fixedly supported inside the outer box 24 in a suspended state by the shock absorbers A and B, and is not inscribed in the outer box 24, so that the impact acting on the outer box 24 is not applied to the ventilation fan 23. The ventilation fan 23 is protected from deformation caused by the impact.

This allows for safe transportation by preventing damage to us and others.

In addition, the first shock absorber A has a part of the bottom plate and a flat flap as the second shock absorber A.
Since it has a double structure due to the semi-sea) 2B, it is particularly excellent in terms of compressive strength in the longitudinal direction.

Moreover, the sheet material 2 constituting the first and second buffer bodies A and B
, 3 are formed by simultaneously cutting out one sheet material 1, so only one mold is required for cutting out each sheet material 2, 3, the manufacturing process is reduced, and the material cost is reduced. The processing cost is low, the production is extremely easy, and the number of parts is small, so it does not take up much space to store materials.

Furthermore, the packaging process is as simple as supporting the ventilation fan 23 on the first cushioning body A and then covering it with the second cushioning body B, so the packaging process is excellent and the unpacking process is also easy. It is.

In addition, it is easier to incinerate waste materials than conventionally used solid cushioning materials such as styrofoam, and the final user is fully considered.

As explained above, according to the present invention, it is possible to exhibit a sufficient buffering function and safely transport products, and
Packaging and unpacking work is easy, and the cushioning body can be constructed from a sheet material that is simultaneously die-cut in one process, so material costs can be kept low, and manufacturing is extremely easy and cost-effective. It can be provided at a low cost.

Furthermore, since a paper sheet material such as a corrugated cardboard sheet material is used as the material, it is easy to incinerate and dispose of the material, which is also effective in preventing pollution.
