DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of packaging technology for packaging a ventilation fan having a large mass with a mounting leg and an impeller provided on a motor.

[0002]

2. Description of the Related Art A ventilating fan having a configuration in which several mounting legs protrude angularly from the outer shell of a motor, and an impeller is mounted on a rotating shaft of the motor has a large number of irregularities, is complicated in shape, and has a large mass. A device is required for the packaging device. For example, Japanese Patent Application No. 7-8
No. 317 shows a packaging apparatus using a bottom C-type box made of corrugated paper with an open top and a top C-type box made of corrugated paper with an open bottom. In this packaging apparatus, as shown in FIG. 9, several girders (not shown) formed by laminating corrugated paper are fixed to the lower surface of the bottom C-type box 101, and the bottom of the bottom C-type box 101 is heavy. Has been reinforced.

[0003] In a bottom C-type box 101, four mounting legs 1 protruding from a motor 103 with an impeller 102 facing down.
The ventilation fan is housed so that 04 is in the diagonal direction of the bottom C-type box 101. The outer periphery of the ventilation fan on the bottom C-type box 101 has one end inserted along the inner wall surface of the bottom C-type box 101, and the cushioning member 1 made of corrugated cardboard is assembled as a whole in a rectangular tube shape.
05 is surrounded by a gap. The free ends of the mounting legs 104 of the ventilation fan fit into the four corners of the cushioning member 105, thereby restricting the movement of the ventilation fan. An upper C-type box is provided at the upper end of the buffer member 105 with the motor 1.
03 is covered with a lid with a gap, and the whole is bound by a resin band. In this packaging device, the cushioning member 1
05 has a double structure, the four corners of the packaging device are reinforced, and the bottom C-type box 101 that receives the mass of the ventilation fan is reinforced by a girder. Even a heavy ventilation fan can be packaged in a stable state.

[0004]

In the conventional ventilation fan packaging apparatus as described above, each mounting leg 1 is located at the corner of the cushioning member 105.
Since the free end side of 04 is fitted, the ventilation fan in the packaged state does not rotate, but there is a problem that it can be applied only to the case where the mounting legs 104 protrude diagonally. Further, when the vertical vibration is repeatedly applied to the whole, the ventilation fan moves because the ventilation fan in this direction has almost no constraint. When the ventilation fan moves up and down, the mass is concentrated at the center and the load concentrates on a part of the bottom C-type box 101, and the girder where the load concentrates because the entire corrugated cardboard girder cannot bear the load It may be broken and the packaging may be damaged.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a highly constrained ventilation fan package capable of fixing a ventilation fan with a simple structure and preventing rotation. The purpose of the present invention is to obtain a device, and to obtain a high-strength ventilation fan packaging device capable of packaging a large-mass ventilation fan in a stable state, thereby facilitating the separation of constituent materials when the ventilation fan packaging device is discarded. That is.

[0006]

According to a first aspect of the present invention, an impeller is mounted on a rotating shaft of a motor, and the outer shell of the motor is radially larger than the outer diameter of the impeller. Regarding the packaging of a ventilation fan having a plurality of mounting legs extending outward, a hexahedral lower box with an open upper surface is formed of corrugated paper, and a plurality of girders are fixed to the lower surface of the lower box. On the motor fixing surface having a fitting part to which the anti-impeller side of the motor is fitted, a support surface is provided on the four circumferences of the motor fixing surface, and the bottom holder, which is entirely formed of corrugated cardboard integrally molded, has a motor fixing surface facing downward. It is fitted on the bottom surface of the box at a distance so as to be supported by four supporting surfaces. Then,
The motor impeller side is fitted to the fitting part of the motor fixing surface of this bottom holder, and the motor mounting leg is supported by the motor fixing surface, and the motor is lifted from the bottom of the lower box and held on this lower box. The surroundings of the ventilated fan are enclosed with a gap by a square tubular body wrapping material made of corrugated cardboard having a protruding portion having a pressing surface for pressing the free end side of each mounting leg of the ventilating fan from above from the upper side. Then, a means is adopted in which an upper box made of a hexahedral corrugated cardboard with an open lower surface is covered on the upper end of the body packaging material in a lid shape with a gap with respect to the impeller, and the whole is bound.

According to a second aspect of the present invention, a motor is provided on the bottom surface of the lower box between the bottom surface of the lower box and the end surface of the motor supported by the bottom holder. Means for interposing a reinforcing member that abuts on a contact surface having an area larger than the end surface of the contact member is adopted.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. Embodiment 1 of the Invention The ventilation fan to which the ventilation fan packaging device according to the first embodiment shown in FIGS. 1 and 2 is applied has an impeller 2 mounted on a rotating shaft of a motor 1, and the outer shell of the motor 1 is provided with the impeller 2 in a radial direction. It has a plurality of mounting legs 3 projecting outward from the outer diameter, such as two, three or four, and each of the mounting legs 3 has a mounting surface 4 parallel to the rotating surface of the impeller 2 at the free end side. And a mass of 20 kg or less (the optimal mass is about 15 kg).

This ventilating fan packaging apparatus comprises a lower box 5 forming a bottom, an upper box 6 forming a top, a bottom holder 7 incorporated therein, a body packaging material 8 forming an outer periphery, and a binding band 9. , Except for the binding band 9, all of which are made of corrugated paper. The lower box 5 is a hexahedral C with an open top.
Formed as a formula box and has a low standing peripheral side wall. On the lower surface of the lower box 5, a plurality of girders 10 formed by laminating corrugated paper at intervals and forming a square bar shape are fixed. Upper box 6
Is the same size as the lower box 5, is formed as a hexahedral C-type box with an open lower surface, and has a low standing peripheral side wall.

The bottom holder 7 is mounted on the bottom surface in the lower box 5 and has a fitting portion 11 which is a hole for fitting the counter fan side of the motor 1 of the ventilation fan. As a whole, the support surface 13 is provided on the four circumferences to form a trapezoidal integral molded product. The developed shape of the bottom holder 7 is as shown in FIG. That is, the flange portion 14 having the same width is bent on the opposite side of the rectangular corrugated cardboard to form a ruled line 15.
The rectangular corrugated board is divided into three parts, a center and both sides. At the center of the central part, a rectangular motor fixing surface 12 is defined by four rounded bending rules 15,
A fitting portion 11 is punched in the center. A ruled line 16 by half-cutting is provided between four corners of a central portion and a motor fixing surface 12 defined at the center.
The edges at both ends of the central portion are slightly cut so as to be located slightly inward from the entire edges. The half-cutting process is a process of cutting one side of the corrugated cardboard without cutting the other side and the corrugated material. 1 is obtained by bending each ruled line 15 while squeezing each of the ruled lines 16 formed by half-cutting the expanded corrugated paper into an inward gusset shape.
A three-dimensional bottom holder 7 having a trapezoidal shape as shown in FIG.

The bottom holder 7 thus formed has a support surface 13 formed by inclined surfaces with the motor fixing surface 12 formed on both long sides thereof and a vertical support surface 13 formed on both short sides thereof. Thus, the supporting member is supported above the flange portion 14. The projection plane connecting the outer periphery of the flange portion 14 coincides with the bottom surface of the lower box 5.

The body wrapping material 8 is formed by combining four U-shaped cushioning materials 17 formed by bending a rectangular corrugated board. In other words, two U-shaped cushioning members 17 face each other, and two cushioning members 17 face each other such that the corners overlap the corners of the outer cushioning member 17 to form a square cylindrical body packaging. Combined as material 8. The body packaging material 8 having such a shape can be made of a single piece of corrugated cardboard. However, it is easier to store each of the body packaging materials 8 in a smaller configuration, and it is possible to form the double structure portion 18. Therefore, strength is obtained and it is convenient.

A protrusion 20 having a pressing surface 19 for pressing the mounting surface 4 from above at a position corresponding to the mounting surface 4 of each mounting leg 3 of the ventilation fan is provided on the inner surface of the body wrapping material 8. It is constituted by the fixation of the body. The pressing surface 19 is formed on the lower surface of the protruding portion 20, and is located higher than the lower end of the trunk portion packaging material 8.

In this ventilating fan packaging apparatus, first, the bottom holder 7 is fitted into the lower box 5 having the above-described structure in a restricted state with the motor fixing surface 12 facing upward. Then, the motor 1 of the ventilation fan is fitted into the fitting portion 11 of the bottom holder 7 from the side opposite to the impeller to a position where each mounting leg 3 contacts the motor fixing surface 12. In this state, the end of the motor 1 on the side opposite to the impeller is a motor fixing surface 12.
At a height above the bottom surface of the lower box 5 by setting the height of the lower box 5.
Thereafter, one end of the periphery of the ventilation fan held on the lower box 5 is fitted into the lower box 5, and the mounting surface 4 of each mounting leg 3 of the ventilation fan is pressed from above by the pressing surface 19 of each projection 20. It is positioned and enclosed with a gap by a square tubular body packaging material 8. Further, the upper box 6 is attached to the upper end of the body packaging material 8 by the impeller 2.
Is covered in a lid shape with a gap, and finally the whole is tied with a tying band 9 to complete the packaging.

In this ventilation fan packaging apparatus, the mounting legs 3 of the ventilation fan
Regardless of whether the number is two, three, or four, it can be easily handled by providing the corresponding number of protrusions 20. The ventilation fan in the package state is the motor fixing surface 12 of the bottom holder 7.
Is fixed so as to be pressed by each protrusion 20,
It is in a restricted state where it cannot rotate or move up and down. In this state, if vertical vibration is repeatedly applied to the whole,
Part of the inertial force due to the mass of the ventilation fan is dispersed as lateral force to each flange portion 14 by the oblique support surface 13, and the force acting in the vertical direction is carried by the vertical support surface 13, and the lower box 5 The load is concentrated on a portion of the slab, and the load is not concentrated on the corrugated cardboard girder 10. Therefore, a stable packaging function can be exhibited even with a fairly heavy ventilation fan. Since the bottom holder 7 is an integrally formed body having no cutting line, it has a high strength against a compressive load and can firmly support the ventilation fan. Since the ventilation fan packaging device is almost entirely made of corrugated cardboard, it is easily disposable and the material can be easily reused.

Embodiment 2 of the Invention In the second embodiment, the strength of the above-described ventilation fan packaging apparatus of the first embodiment is increased, and the mass of 20 kg to 25 kg is large.
It is devised so that it can be applied to packaging of a ventilation fan of about Kg. However, since the basic configuration is the same as that described in the first embodiment, the same portions as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

As shown in FIGS. 3 and 4, the ventilation fan wrapping device according to the second embodiment is configured such that the bottom surface of the lower box 5 of the ventilation fan wrapping device according to the first embodiment and the end face of the motor 1 supported by the bottom holder 7 are connected. The reinforcing member 22 is interposed between the bottom surface of the lower box 5 and a contact surface 21 having an area larger than the end surface of the motor 1. The reinforcing member 22 is formed in a U shape as shown in FIG.
The web portion contacts the bottom surface of the lower box 5 and rises 23 on both sides.
Is in contact with the rear surface of the motor fixing surface 12 along the long side thereof. That is, the motor fixing surface 12 is reinforced by the reinforcing member 22 on the back surface, and the support strength is improved. The material of the reinforcing member 22 can be made of a pile of corrugated cardboard, a rigid wood, or the like, and can be selected according to the required strength.

Although the reinforcing member 22 having the above structure is a channel type and is effective for reinforcing the motor fixing surface 12, even a simple flat plate-shaped reinforcing member 22 has a corresponding reinforcing effect. That is, vertical vibration is applied in the package state, and the motor fixing surface 1
In the case where the motor 2 is bent up and down, when the end face of the motor 1 directly hits the bottom surface of the lower box 5, the load concentrates there, and the beam 10 may be damaged. Is received over a large area, so that this can be avoided. In this ventilating fan packaging apparatus, since constituent members made of different materials are not in a fixed relation, it is easy to separate constituent materials at the time of disposal. The other functions are the same as those of the first embodiment, and the description thereof will be omitted.

Reference Example 1 The configuration of the ventilation fan to which this reference example 1 is applied is the same as that of the first embodiment, but the mass is heavier, about 30 kg. Note that the same parts as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The ventilation fan packaging device of the first embodiment is shown in FIG.
As shown in FIGS. 6 and 7, the bottom holder 7 of the ventilating fan packaging apparatus shown in the first embodiment is mounted on a pallet 24 made of a rigid body (preferably in the sense that wood is easily discarded or reused, but plastic may be used). The replacement and the fixing of the mounting legs 3 are performed by a structure provided on the pallet 24. That is, the screw hole 25 provided at the free end of the mounting leg 3
Is used as it is for fixing the motor 1. A pallet 24 made of a rigid body and shaped like a girder is fitted in the lower box 5 in a restrained state. The pallet 24 is configured such that the upper beam structure 27 is closer to the middle side than the lower girder 26. The end face of the motor 1 on the side opposite to the impeller is mounted on the center of the pallet 24. A rigid mounting piece 28 corresponding to each mounting surface 4 and receiving the mounting surface 4 is fixed to the beam structure 27 of the pallet 24 where the mounting surface 4 of each mounting leg 3 of the motor 1 in the ventilation fan in this state is located.

The end face of the motor 1 on the side opposite to the impeller is placed on the center of the pallet 24, and the mounting piece 28 is received by the mounting surface 4 of each mounting leg 3 at the corresponding position, and mounted using the screw holes 25 thereof. A screw 29 is fastened to the piece 28 to fix the ventilation fan. The periphery of the ventilation fan fixed on the pallet 24 is surrounded by a body packaging material 30 made of corrugated cardboard having a double U-shape, and an upper box 6 is formed on the upper end of the body packaging material 30 in a lid shape. The packaging is completed by covering the entire body with a tying band 9 after covering. The lower edge of the body packaging material 30 is placed on the spar 26 of the pallet 24 and is brought into close contact with the end face of the beam structure 27.

In this ventilating fan packaging apparatus, no spar is required on the lower surface of the lower box 5 because the pallet 24 bears the load. Depending on the strength of the pallet 24, it can be used for a ventilation fan having a considerably large mass. The screws 29 used for fixing to the pallet 24 are those that are actually used for mounting the ventilation fan, so that the accessories of the ventilation fan are included as they are and the packaging form is included, so that the screws 29 for mounting are not lost. be able to. In this ventilating fan packaging apparatus, since constituent members made of different materials are not in a fixed relation, it is easy to separate constituent materials at the time of disposal.

Reference Example 2 The configuration of the ventilation fan to which this reference example 2 is applied is the same as that of the reference example 1, and its mass is also about 30 kg. In addition,
The same parts as those of the reference example 1 are denoted by the same reference numerals, and their description is omitted.

As shown in FIG. 8, the ventilation fan packaging device of the second embodiment has the same structure as the beam 26 and the beam 26 of the pallet 24 of the ventilation fan packaging device shown in the first embodiment. And the body packaging material 30 is made of an outer box made of covered corrugated paper with an open lower surface (half-open A-type box JIS-Z-1507).
Code number 0200) 31. The fixing of the mounting leg 3 of the ventilation fan is performed by a mounting piece 28 provided on the pallet 24. The outer box 3 is attached to the pallet 24 in addition to the mounting pieces 28.
A fixed piece 32 made of a rigid body and fixed along the open end is fixed. The end face of the motor 1 on the side opposite to the impeller is mounted on the center of the pallet 24. Other configurations are the same as in the first embodiment.

In this ventilating fan packaging apparatus, the end face of the motor 1 on the side opposite to the impeller is mounted on the center of the pallet 24, and each mounting piece 2
8, the mounting surface 4 of each mounting leg 3 is received at the corresponding position, and the screw 29 is fastened to the mounting piece 28 using the screw hole 25 to fix the ventilation fan. The surroundings and the upper side of the ventilation fan fixed on the pallet 24 are surrounded by an outer box 31 with a gap, and the outer box 31 and the pallet 24 are bound by the binding band 9 to complete the packaging. The lower edge of the outer box 31 is a fixed piece 32 and a mounting piece 2 on the pallet 24.
8 to the outer surface.

Since the pallet 24 bears the load, this ventilation fan packaging apparatus can also be used for a ventilation fan having a considerably large mass depending on the strength of the pallet 24. By using the screws 29 used for fixing to the pallet 24 that are actually used for mounting the ventilation fan, the attached parts are packaged as they are, and loss of the mounting screws 29 can be prevented. This ventilating fan packaging device can be transported on a pallet because there is no lower box 5, and is easy to handle. In addition, since constituent members made of different materials are not in a fixed relation, it is easy to separate constituent materials at the time of disposal.
