Description

[Detailed Description of the Invention] The present invention relates to a packing device that compactly packs fan blades and guards and prevents them from damaging each other.

In general, packaging equipment for export fans, etc. does not store the components of a single fan in a single outer box, but instead stores an appropriate number of components of the same type in a single box. .

Taking into consideration the shape of the component parts, it is common to use a packaging device that wraps an appropriate number of blades with an appropriate number of guards and stores them in a single box, and prior art related to this is disclosed in Japanese Utility Model Publication No. 47-36545. (hereinafter referred to as conventional example).

The packaging device shown in the conventional example consists of a packaging box made of corrugated paper or the like, and a substantially cylindrical storage frame made of corrugated paper that is sandwiched between front and rear protective frames stored in the box and that stores the feathers inside. A holding piece is formed on the inner surface of the storage frame to prevent rotation of the blade, which is interposed between the blade pieces of the blade, and a holding piece for preventing vertical movement is provided at both end openings of the storage frame to press the boss portion of the blade. are integrated into one.

However, no consideration is given to the inclination of the blade with the boss portion of the blade as a fulcrum.

That is, when the blades are tilted, the edges of the blades protrude beyond the storage frame, so the edges of the blades come into contact with the protective frame and damage each other.

In view of the above points, the present invention provides a packaging device that has a simple structure, allows for easy packaging without increasing the number of packaging materials, and prevents the blades and guards from damaging each other. An embodiment of the present invention will be explained with reference to FIGS. 1 to 7.

In this embodiment, the blades 1, the front guard 2, and the rear guard 3, each corresponding to four electric fans, are housed in one exterior box 4.

The blade 1 consists of a boss part 5 that is attached to an electric motor of a fan, and a plurality of blade pieces 6 formed around the boss part 5.

The blade pieces 6 are fan-shaped and twisted in order to improve air blowing efficiency.

The four blades 1 are stacked on top of each other like a packing bandwagon.

Two sets of two blades 1 are stacked with one side facing upward and the other side facing downward (hereinafter, this combination will be referred to as blade body A).

A portion of each blade piece 6 of the blade body A is positioned so that the blade pieces 6 are spaced apart from each other and face each other without abutting each other at their edges, and a protective paper (not shown) is placed between each blade 1. do not)
to intervene.

The front guard 2 and the rear guard 3 are made up of four overlapping pieces: the front guard 2 has only the front guard, and the rear guard 3 has only the rear guard (hereinafter, the overlaid pieces are referred to as guard bodies B and C).

A protective paper (not shown) is interposed between each guard of the guard bodies B and C.

Reference numeral 7 denotes a substantially cylindrical buffer made of corrugated paper which is held between the guard bodies B and 0. The inner diameter of the buffer 7 is approximately the same as the outer diameter of the blade 1.

The blade body A is housed within the buffer body 7. Cut grooves 8 are provided at the same intervals on both ends of the buffer body 7, and a plurality of flaps 9 are formed.

The folding portion 10 of the flap 9 crushes the corrugated paper to facilitate the creation of a new song on the flap.

Reference numeral 11 denotes an inner buffer body inserted into the buffer body 7, and both ends of the buffer body 11 are located close to the bent portion 10 of the flap 9.

Next, the action will be explained.

The one guard body C is housed in the outer box body 4.

At this time, the guard body C is stored with its outside facing down and its inside facing up.

Thereafter, the buffer body 7 with the inner buffer body 11 inserted therein is placed on the guard body C, and the buffer body 7 is pressed.

By doing so, the flap 9 is guided by the sloped portion inside the guard body C and is bent and sewn inward.

Even if it takes time and effort to bend the flap 9 inward in advance, the flap 9 can be folded simply by pressing it against the inside of the guard body C.

Next, after the blade body A is housed in the buffer body 7, the other guard body B is placed on the buffer body 7.

At this time, the inner side of the guard body B is in contact with the buffer body 7, and by pressing the guard body B, the flap 9 is guided by the inner surface of the guard body B and bent inward in the same manner as described above.

Finally, the upper opening of the outer box 4 is closed with the inner and outer flaps of the box to complete the packaging.

In the packed state, even if the blade 1 housed in the buffer body 7 is tilted, the corner edge 6a of the blade piece 6 will not directly contact the guard bodies B and C, but will contact the flap 9. This prevents damage to the guard and blades.

Furthermore, since the inner buffer body 11 is provided in this embodiment, it functions as a reinforcing material for the buffer body 7.

The edge of the inner buffer body 11 is connected to the bent portion 10 of the flap 9.
Therefore, even if the cut groove 8 is cut too far when forming the flap 9, the flap 9 will be bent to a certain length.

If the flap 9 is further bent inward and separated from the inside of the guard, when the blade 1 rotates, the flap 9 may ride on the corner edge 6a and the corner edge may come into direct contact with the guard, causing damage. In this embodiment, the edge of the inner buffer body 11 restricts it, so that the flap 9 is held in contact with the inner surfaces of the guards 2 and 3.

What is shown in FIGS. 8 and 9 is another embodiment of the present invention.

Since the cut groove 8 provided in the buffer body 7 is formed in a V-shape, and the flap 9 is made into a substantially uniform trapezoid shape, when the flap 9 is bent by the pressure of the buffer body 7, the side of the flap The edges, especially the corners, do not stick together and make it difficult to bend, and can be easily bent with a small pressing force.

As described above, the present invention forms a plurality of flaps that can be bent inward by pressing the buffer against the inner slope of the guard by providing cut grooves on both ends of the approximately cylindrical shock absorber sandwiched between the front and rear guards. Therefore, even if the blades housed in the buffer body are tilted, their edge portions will hit the flap and will not directly hit the guard, so that they will not damage each other.

In addition, the flap can be bent simply by pressing the buffer against the guard without having to bend it in advance, so it does not require any effort.
This has great practical effects, such as easy packaging.
