Description

[Detailed Description of the Invention] This invention relates to a packaging device for preventing soiling and damage to ventilation fans during storage or transportation.

Conventionally, in packaging equipment for this type of ventilation fan, a cushioning material is filled in the space between the outer box and the ventilation fan to prevent the ventilation fan housed in the outer box from moving and being damaged during transportation. As the button and shock absorber, molded products made of foamed resin or cardboard materials cut into appropriate dimensions, assembled, and shaped into a predetermined shape by gluing or the like were used.

However, conventional cushioning bodies constructed in this way, for example those made of foamed resin, may cause pollution when disposed of after use, and those made of cardboard material cut into a predetermined shape by gluing, etc. There were drawbacks such as high manufacturing costs.

In addition, in recent years, mass production factories have begun to adopt automatic packaging equipment to increase packaging productivity, but when performing automatic packaging, it is necessary to integrate ventilation fans and cushioning materials. For this purpose, it is necessary to bind the ventilation fan and the buffer with tape or string, which may reduce work efficiency.

This invention aims to improve the above-mentioned drawbacks, and provides a packaging device that is provided with a rear holder that supports the rear part of the ventilation fan and a front holder that supports the front part of the ventilation fan.

An embodiment of this invention will be described below with reference to FIGS. 1 to 5.

Figure 1 is a developed view of the outer box, Figure 2 is a perspective view of the rear holder, Figure 3 is a perspective view of the front holder, Figure 4 is a developed view of the front holder, and Figure 5 is a perspective view of the rear holder. FIG. 3 is a front view of the assembled ventilation fan.

1 is an outer box made of paper board material such as cardboard, 1a indicated by a dotted line is a fold line, 1b is a cut line, 2 is a rear holder, and the rear holder 2 is formed by bending it in contact with 2a and 2b. bottom plate 2Cs side plates 2d, 28, top plate 2f
It is made up of two double bonds.

Reference numeral 3 denotes a front holder made of a paper board material 3a such as cardboard, and the front holder 3 includes front support plates 4a and 4b that support the front surface of the ventilation fan front section 8a, and a side that supports the side surfaces of the ventilation fan front section 8a. between the front support plates 4a and 4b, and between the front support plates 4a and 4b and the side support plates 5a.

5b, and spacer pieces 6a, 6b that maintain a predetermined distance between the ventilation fan front section 8a and the outer box 1.

6o, and a fold line 7 is formed from one paper board 3a.
As shown in FIG. 3, the side support plates 5a and 5b are formed with an inclination such that the width between the ends thereof is narrower than the width of the front part 8a of the ventilation fan.

Next, when packing is carried out using an automatic packing device (not shown), a ventilation fan whose rear part 8b is supported by a rear holder 2 is placed on the outer box 1 which is unfolded into a plate shape as shown in FIG. 8, and then the side support plates 5a, 5 of the front holder 3.
Open between the tips of b, and attach the front holder 3 to the ventilation fan front part 8a.
Attach to.

As a result, the side support plates 5a and 5b hold the sides of the ventilation fan front part 8a due to the elasticity of the paper board 3a.

As described above, the ventilation fan 8 was held together by the rear holder 2 and the front holder 3, and then the outer box 1 was folded along the fold line 1a in a predetermined order using an automatic packaging device, and was integrated with the holders 2 and 3. A box is formed with the ventilation fan 8 housed therein, and the box is sealed with adhesive or the like.

As described above, according to this invention, since all the holders are made of paper material, there is no risk of causing pollution when the buttons are disposed of after use.

Furthermore, since it can be formed by bending a single sheet of plate material, material costs and assembly costs can be reduced, and less space is required for storing materials before assembly and after use.

Furthermore, since the ventilation fan can be assembled together with the holder on the flat outer box, automatic packaging becomes easy and packaging costs can be reduced.
