Description of the Related Art Conventionally, fully automatic washing machines and the like are packed with various cushioning bodies in order to protect products from vibrations and shocks that are received during transportation. In particular, the heavy drive mechanism portion provided on the outer bottom portion of the tank body supported by the elastic suspension mechanism in the outer box is configured to be directly buffered and supported by the bottom cushioning body.

A conventional packaging device will be described below with reference to FIG. FIG. 5 is a sectional view showing a state in which the fully automatic washing machine is packaged.

In FIG. 5, reference numeral 1 denotes a packing device for a fully automatic washing machine 2, which includes a rotating tub (not shown) inside an outer box 3 of the fully automatic washing machine 2 to be packed and a water receiving tub 4 containing the rotating tub therein.
The tank body 5 consisting of the above is swingably supported via the elastic suspension mechanism 6 whose upper part is fixed to the outer box 3 and whose lower part is fixed to the side wall of the water receiving tank 4. Further, a top plate 7 having a lid for opening and closing the laundry entrance and exit on the upper part of the tub body 5 is attached to the upper part of the outer box 3.

Further, on the outer bottom of the tank body 5, a drive mechanism portion 8 provided with an electric motor or the like for rotationally driving the rotary tank is provided so as to be fixed to the water receiving tank 4. A protective frame 9 formed in a substantially U shape is fixed to the drive mechanism 8 to protect the lower end thereof.

The packing of the fully automatic washing machine 2 having the above-mentioned structure is carried out as follows. That is, as for the bottom of the package, a pair of first bottom cushioning bodies 11a, 1 made of Styrofoam are provided on the bottom plate of the bottom box body 10 made of cardboard.
1b are mounted at intervals, and a second bottom buffer body 12 made of styrofoam is dropped in the center of the bottom plate of the bottom box body 10 so as to be sandwiched between the first bottom buffer bodies 11a and 11b. It is installed so as not to.

In the fully-automatic washing machine 2, the lower part of the outer box 3 is fitted to the stepped portion 13 which is carved to follow the shape of the lower part of the outer box 3 of the first bottom cushioning bodies 11a and 11b. 3 is adapted to be supported, and the first bottom cushion 1
The second provided so as to project upward from 1a and 11b
The lower surface of the protective frame 9 of the drive mechanism section 8 is supported on the upper surface of the bottom cushioning body 12.

On the other hand, with respect to the upper part of the packaging, the upper cushion 14 made of Styrofoam, which is molded in conformity with the shape, is attached to the upper part of the fully automatic washing machine 2, and the upper cushion 14 is further attached. A box 15 made of corrugated cardboard whose lower surface is opened from above so as to be sandwiched is covered.
At the same time, the inner surface of the lower end portion of the box body 15 is fitted to the outer surfaces of the first bottom cushioning bodies 11a and 11b and the bottom box body 10. Then, a tightening band (not shown) is wound around the box body 15 and the bottom box body 10 and packed.

For this reason, in the tank body 5 provided with the heavy drive mechanism portion 8, the first bottom cushioning bodies 11a and 11a, 11 are made by bringing the protective frame 9 into contact with the second bottom cushioning body 12.
It is buffered and supported separately from the outer box 3 which is buffered and supported by b. In the packed state, the elastic suspension mechanism 6 and the weight of the tank body 5 and the like do not act on the outer box 3 via the elastic suspension mechanism 6.

However, in the conventional packaging apparatus configured as described above, there is a case in which, for example, the corners are dropped from a high position with the corners on the lower side, and a large impact that damages the corners of the package is generated. Should a force be applied, the first bottom cushioning bodies 11a and 11b and the second bottom cushioning body 12 are displaced from each other, thereby fixing and supporting the tank body 5, the outer case 3, and the like. However, the force due to the displacement acts on the tank body 5, the elastic suspension mechanism 6 for suspending the suspension body 5, or the outer box 3 connected through the elastic suspension mechanism 6,
It is recalled that sufficient product protection cannot be achieved.

[0011]

As described above, conventionally, if a large impact force that damages the corners of the package is applied, the outer box, tank body, etc. can be fixedly supported. Therefore, it is recalled that the product cannot be sufficiently protected. The present invention has been made in view of such a situation,
It is an object of the present invention to provide a packaging device for a washing machine that can sufficiently maintain the fixed support state of the tank body, the outer box, and the like even when a large impact force is applied, and can sufficiently protect the product. .

The same parts as those of the related art will be designated by the same reference numerals, and the description thereof will be omitted. In the figure, 21 is a fully automatic washing machine 2
In the packaging device, the bottom part of the package is configured by combining the pair of first bottom buffer bodies 22a and 22b so that the second bottom buffer body 23 is sandwiched.

The first bottom cushioning members 22a and 22b are in the form of a rectangular shallow dish having a semi-mounted shape, and are molded to have a predetermined shape by, for example, foamed plastic such as Styrofoam. It is molded with a foaming ratio that provides cushioning performance.

Then, the first bottom cushion members 22a, 22b
Has a stepped portion 24 imitating the lower shape of the outer box 3 formed at the time of molding, and forms a storage recess 25 into which the lower portion of the outer box 3 is fitted when combined with the second bottom cushion 23. It is supposed to be done. Reference numeral 26 is a hole formed so that the bottom leg 27 of the fully automatic washing machine 2 can be loosely fitted.

In addition, the second bottom shock absorbers 23 of the first bottom shock absorbers 22a, 22b are combined at the second position.
A concave portion 28 having a shape following the outer shape of the bottom cushioning body 23 is formed. Then, the second bottom cushion 2
3 is fitted so that the first bottom cushion 22
The a and 22b and the second bottom cushion 23 are prevented from moving relative to each other in the horizontal direction and being displaced.

Further, a groove 29 having a predetermined cross-sectional shape, which is opened in the middle portion in the thickness direction and is cut in the horizontal direction, is provided in the recess 28 and the portion adjacent thereto.

On the other hand, the second bottom cushion 23 has a substantially rectangular parallelepiped shape in which a tapered surface is formed on the upper portion of the opposite side, and is molded into a predetermined shape by using foamed plastic such as styrene foam. It is molded with a foaming ratio so as to obtain a predetermined cushioning performance.

A collar 30 extending horizontally from an intermediate portion in the thickness direction is integrally formed on a side portion of the second bottom cushioning body 23 which is combined with the first bottom cushioning bodies 22a and 22b. There is. The thickness of the collar 30 is substantially equal to the width of the groove 29 described above, and when the collar 30 is fitted in the groove 29 when combined with the first bottom cushioning bodies 22a and 22b, the first bottom cushioning body is formed. 22a and 22b and the second bottom cushion 23 are prevented from moving relative to each other in the vertical direction and being displaced.

Further, the second bottom cushion 23 has such a height that it can support the lower surface of the protective frame 9 of the drive mechanism 8 on the upper surface when combined with the first bottom cushions 22a and 22b. As described above, the upper part thereof projects upward from the upper surface of the storage recess 25. The second bottom cushion 23 and the first
The bottom surfaces of the bottom cushioning members 22a and 22b are so formed as to be flush with each other when combined. Reference numeral 31 is a bottom box that is the same as the conventional bottom box 10.

Therefore, the packing of the fully automatic washing machine 2 is performed as follows. That is, the first bottom cushion 22a,
22b and the second bottom shock absorber 23 are assembled by fitting the second bottom shock absorber 23 into the recess 28 while fitting the collar 30 into the groove 29, and housed in the bottom box body 31. .

Then, the lower portion of the outer box 3 is carved into the storage recess 25 of the first bottom cushioning members 22a and 22b.
The lower part of the outer box 3 is fitted into the housing. At the same time, the drive mechanism portion 8 is supported on the upper surface of the second bottom cushioning member 23 such that the lower surface of the protective frame 9 abuts on the upper surface. The upper part of the package has the same structure as the conventional one, and after the upper cushioning body 14 is mounted, the box body 15 is fitted and the tightening band (not shown) is provided on the box body 15 and the first bottom cushioning body 22a.
It is wound around 22b and packed.

With the above-mentioned structure, the tank body 5 provided with the heavy drive mechanism portion 8 is brought into contact with the second bottom cushioning body 23 by contacting the protective frame 9 with the first bottom cushioning body 23. It is buffered separately from the outer box 3 buffered and supported by the bottom buffers 22a and 22b, and in the packed state, the elastic hanging mechanism 6 and the outer box 3 are prevented from being acted on by the elastic suspension mechanism 6 and the elastic suspension mechanism 6 via the elastic suspension mechanism 6. Has become.

In addition, during transportation or during handling of a load accompanying this, for example, the product may drop from a high position with the corners on the lower side, which may damage the corners of the package. Even if an impact force is applied, the first bottom shock absorbers 22a and 22b and the second bottom shock absorber 23 are
Since the horizontal movement is restricted by the concave portion 28 and the vertical movement is restricted by the fitting of the collar 30 and the groove 29, no positional deviation occurs between the two.

Therefore, the first bottom cushion members 22a, 22
The outer box 3 and the tank body 5 that are buffered and supported by the b and the second bottom cushioning body 23 are maintained in a fixed supporting state, and the tank body 5 and the elastic suspension mechanism 6 for suspending the same are elastically suspended. The outer box 3 connected via the mechanism 6 does not have a force that would damage them, and thus the product can be sufficiently protected.

As the supporting member for protecting the product forming the bottom of the package, the first bottom cushioning member 22a,
The bottom box 31 used as one of the supporting members may be omitted or simplified as unnecessary.

It should be noted that the present invention is not limited to the above-described embodiment, but the relative movement in the vertical direction between the first bottom buffer bodies 22a, 22b and the second bottom buffer body 23 can be prevented. The structure of the limiting groove 29 and the flange 30 may be provided on the opposite bottom cushioning bodies, or may be formed to have an engaging shape such as another male-male relationship shape, which does not depart from the gist. It can be implemented by appropriately changing within the range.
