Description

[Detailed explanation of the idea] This proposal relates to improvement of packing equipment for ventilation fans.

Conventionally, ventilation fans are packaged by sandwiching the ventilation fan between foamed resin cushioning bodies on both sides, and then wrapping the fan in a band-shaped exterior body or storing it in an exterior box.

However, this buffer is bulky and wastes a large space until it is used for packaging.

Furthermore, when the buffer is incinerated, harmful gases are emitted, which makes it difficult to dispose of it in the market, creating a problem.

In view of the above points, this proposal provides a packaging device mainly made of corrugated paper so that it is not bulky and can be easily processed in the market by minimizing the use of foamed resin. This will be explained with reference to FIGS. 1 to 4.

Reference numeral 1 denotes a ventilation fan, which consists of a ventilation fan main body 4 made of sheet metal to which a motor 3 is fixed via a mounting rod 2, and a grille 6 in which a wind tunnel 5 is formed and attached to the front surface of the main body 4.

The main body 4 is formed into a rectangular tube shape, and has a rear surface pivotally supporting a plurality of shutters 7 that are opened and closed in conjunction with a motor control switch (not shown).

A fan 8 having a boss portion that fits onto the motor is attached to the rotating shaft of the motor 3 by a spinner 9 so as to be located within the wind tunnel 5.

The grille 6 has a flange piece 10 stretched over the front edge of the main body 4.
It is removably attached using the elasticity of the grille.

Reference numeral 11 denotes an outer box made of corrugated paper that houses and holds the ventilation fan 1. The ventilation fan stored in the outer box 11 has the main body 4 fitted and held by the main holder 12, and the grille 6 and the outer box. The grille 6 is pressed and held by a spacer 13 interposed between the grille 6 and the grille 6 .

The spacer 13 is made of a sheet of rectangular corrugated paper, and the two spacers 13 are formed by bending opposite ends of the cardboard to form rectangular tube portions 14 and 14.
When the grille 6 is interposed between the grille 6 and the outer box 11, the square tube portion 14 contacts the grille 6, and the grille 6 is held down so that it does not directly contact the outer box 11.

The main holder 12 is formed by bending a sheet of substantially rectangular corrugated paper.

The corrugated paperboard has four side walls 16a, 16 forming a rectangular tube portion 15 that fits and holds the main body 4 when bent.
b, 16C, 16d into bent parts 17a, 17b
, 17C, and 17d.

18 is a margin for forming the square tube portion 15.

The upper edge of the square tube portion 15 has a flap 19a whose edge abuts against the inner surface of the outer box 11.

19 b , 19 C, and 19 d are formed.

The flaps have bent portions 20 a , 20 b , 20 C
, 20d from the four side walls, and each flap 19a, 19b, 19C.

Between 19d are L-shaped notches 21 a , 21 b , 21
Separated at C.

The flaps 19 a , 19 C are formed on the side walls 16 a , 16 C of the rectangular tube portion 15 , and are longer than the side walls 16 a , 16 C, and their length is longer than that of the outer box 11 .
The length is set to be the same as the opposite side of the inside surface.

Therefore, when the main holder 12 is inserted into the outer case 11, both end portions of the flaps 19a and 19C abut against the corners of the outer case 11.

Reference numeral 22 denotes a tongue piece formed on the lower edge of the side walls 16a, 16C of the square tube part 15. It is fixed in that position.

By fixing the tongue piece 22 in that position, the main body 4
A support part that supports the lower end is configured.

The dimension from the upper edge of the bent tongue piece 22 to the upper edge of the square tube part 15 is set to be equal to or shorter than the length of the main body 4.

Next, the action will be explained.

The flap 19a is formed by bending the corrugated paper at the bending portion and connecting the adhesive margin 18 to the side edge of the side wall 16d to form the rectangular tube portion 15.

19 b , 19 C, and 19 d are bent to make the flap protrude from the upper edge of the rectangular tube portion in a flange shape, and the tongue piece 22
The main holder 12 is assembled by bending it inward and fixing it to form a support part.

Thereafter, the main holder 12 is housed in the outer box 11, the main body 4 of the ventilation fan 1 is fitted into the rectangular tube part 15, and its lower end is placed in contact with the support part, and the spacer 13 is attached to the grill 6.
After placing it on the top surface, the outer box 11 is closed.

In this state, the lower edge of the main holder 12, the edges of the flaps 19a, 19b, 19c, 19d, and the spacer 13 are in contact with the inner surface of the outer box 11, so that the ventilation fan 1 does not directly touch the outer box 11. Moreover, it is securely held so that it does not move within the outer box 11.

Further, the main body 4 has its lower end supported by a support portion, and in this embodiment, the flange piece 10 of the main body 4 and the lower edge of the periphery of the grill 7 do not come into contact with the flap and the upper edge of the square tube portion 15.
The external force applied to the outer box 11 is transferred to the main body 4 via the main holder 12.
No external force is applied to the lower end and to the weaker strength of the flange piece 10 and the lower edge of the periphery of the grille 6.

Even if the upper edge of the square tube part 15 and the flasp are in contact with the flange piece 10 and the lower edge of the periphery of the grille 6, the external force applied to the main body 4 through the main holder 12 is dispersed and applied to the weaker parts. It will not damage the product.

5 and 6 show a second embodiment of the present invention, in which four side walls 16a, 16b, 16 constituting the square tube portion 15 are shown.
The lengths of two opposing side walls 16b and 16d of C and 16d are approximately half the length of the other two side walls 16a and 16C, and a U-shaped cut 24.
24 and cut and raised pieces 25 and 25 are formed.

The cut and raised pieces 25, 25 are the ridge-angled cylinder portion 15 which is folded in half.
It is bent and fixed so as to come into contact with the inner surface, thereby forming a support portion for the lower end of the main body 4.

In this embodiment, the amount of corrugated paper used can be reduced compared to the previous embodiments.

Further, as shown in FIG. 6, when punching out two main holders 12 from a sheet of corrugated paper, the four side walls 16a, 16 of the square tube portion 15
b, 16C.

If the pieces 16d are punched out so that they are combined with each other, the amount of wasted corrugated paper can be minimized.

FIGS. 7 and 8 show third and fourth embodiments of the present invention, and show various methods of cutting and bending the cut and bending pieces in the second embodiment.

Figure 7 shows T-shaped cuts 2 at the bottom of side walls 16a and 16C.
6 is formed and opened and fixed to each cut and raised piece 27 and 27.

FIG. 8 shows a short side wall 16. A new piece 28 is formed by punching out the parts of b and 16d that will be discarded while connected to the other side walls 16a and 16C, and the bent pieces 28 are used to form a rectangular frame at the bottom of the side walls 16a and 16C. This is a fixed version of the new song.

Although there are various other methods of forming the support portion shown in the above embodiments, the present invention does not exclude them.

As described above, in the present invention, since the main holder that fits and holds the ventilation fan body is formed by folding corrugated paper, it can be easily incinerated on the market.

The main holder includes a rectangular tube portion that abuts the side surface of the main body, a flap formed on the upper edge of the rectangular tube portion and abuts the inner side surface of the outer box, and a bent portion formed at the bottom of the rectangular tube portion, and Since it is constructed with a support part whose upper edge touches the lower end of the main body and whose lower edge contacts the inner surface of the outer box, the external force applied to the outer box is transferred to the lower end of the main body, the strongest part of the main body, through the main holder. In addition, damage to the main body can be minimized, which has great practical effects.
