Description

[Detailed Description of the Invention] The present invention relates to a device for compactly packing fan blades and guards.

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. .

In consideration of 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.

However, if the guard is stored in the box in an inclined state, an unreasonable force is applied to the guard, causing it to deform.

In view of the above points, the present invention provides a device that prevents the guard from tilting and also allows easy packaging.An embodiment of the present invention will be described below with reference to the drawings.

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 as follows during packaging.

Two sets of two blades 1 are stacked one on top of the other with one facing upward and the other 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 spaced apart from each other and placed so as to face each other without abutting each other at their edges, and a protective paper (not shown) is placed between each blade 1. ) to intervene.

The front guard 2 and the rear guard 3 are made by stacking four identical guards (hereinafter, the stacked pieces will be 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 cushioning body made of corrugated paper which is sandwiched between the guard bodies B and C so as to cover them. form

The inner diameter of the buffer body 7 is formed to be approximately the same as the outer diameter of the blade 1, and the blade body 1 is housed within the buffer body 7.

The corrugated paperboard 8 is laterally divided into three equal parts at the bending part 9,
V-shaped grooves 10 are formed at the upper and lower parts of the bent portion 9,
A plurality of flaps 11 are formed.

The new bend portion 12 of the flap 11 is made of crushed corrugated paper to facilitate folding of the flap.

On both sides of the corrugated paperboard 8, flaps 13 are formed which are slightly shorter than between the folds 12 and 12.

The corrugated paper 8 is glued to each other's flaps 13, 13,
They are joined by using a conventional joining means such as a stapler, thereby forming the buffer body 7.

At this time, the flaps 13 are joined so as to extend in the longitudinal direction on the outside of the cushioning body.

Next, the action will be explained.

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

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

After that, the buffer body 7 is placed on the guard body C, and the buffer body 7 is placed on the guard body C.
Press.

Since the flap 11 is also formed on the upper part of the buffer body 7, this pressing cannot be performed by applying strong force to the upper part.

However, in the present invention, a flap 13 is provided protruding from the side surface of the buffer body 7, and the flap 13 can be held and pressed.

By doing so, the flap 11 is guided by the inclined portion inside the guard body C and is bent inward.

Therefore, even if it takes time and effort to bend the flap 11 inward in advance, the flap 11 can be bent simply by pressing it against the inside of the guard body C.

Moreover, even if a strong force is applied to the buffer body 7, the flap 13
comes into contact with the outer periphery of the guard body C, so that the flap 1
1 is not too bent.

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 11 is guided by the inner surface of the guard body B and bent inward in the same manner as described above.

At this time, since the outer circumference of the guard body B comes into contact with the flap 13, the flap 11 does not bend too much.

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

The blade 1 stored in the buffer body 7 in the packed state
Even if the blade pieces 6 are tilted, the corner edges of the blade pieces 6 are guard bodies B and C.
The guard and the blades will not be damaged because they do not come into direct contact with the flap 11, but the flap 11.

Since the outer peripheral portions of the guard bodies B and C are in contact with the flap 13, the guard bodies B and C are not tilted relative to the buffer body 7 due to vibrations during transportation, and are stably held. Even if an external force acting on the outer box acts on the guard bodies B and C, it is efficiently absorbed and no unreasonable force is applied.

Further, since the flap 13 is in contact with the inner surface of the outer box 4, the force applied to the outer box 4 can be absorbed by the buffer body 7.

As described above, the present proposal consists of an outer box body made of corrugated paper, etc.
A substantially cylindrical cushioning body made of corrugated paper is provided, which is sandwiched between the front and rear guards housed in the box body, and the blades are housed inside the cushioning body, and a flap is formed on the outside of the cushioning body, with which the outer periphery of the guard comes into contact. Since the guard is installed in the box, it has great practical effects, such as preventing the guard from tilting inside the box and causing no unreasonable force to be applied to it.
