〔Example〕

1 to 3 are diagrams showing the structure of the packaging device as a premise for the convenience of understanding the configuration of one embodiment of the packaging device of the present invention shown in FIG.
The figure is a perspective view of the packaging device, FIG. 2 is a partially cutaway perspective view of the box 3, and FIG. 3 is a sectional view taken along the cutting line - of FIG. 1.

In FIGS. 1 to 3, parts corresponding to the configuration of the prior art (FIGS. 5 and 6) are given the same reference numerals.

The present invention and the packaging device 20 on which it is based basically consist of two support rods 2 supporting a component unit 2 having the same configuration as that shown in the prior art.
1, and a frame 23 having through holes 22 through which both ends of the support rod 21 are individually inserted. The two support rods 21 are made of a rod-shaped body such as metal, vinyl chloride, or cardboard, and are formed into a columnar shape. These support rods 21 have the same shape and are respectively inserted into the rectangular tube portion 16 of the support member 9 constituting the component unit 2. The outer diameter of the support rod 21 is the square tube portion 1.
The space is selected to be slightly smaller than the space in the thickness direction of the tube 6, which allows insertion into the rectangular tube portion 16.

The two support rods 21 are inserted into the square tube part 16 so as to be spaced apart from each other and in contact with the side inner walls of the square tube part 16, respectively. These support rods 21
Each length in the axial direction is selected to be longer than the distance connecting both opening ends 16a and 16b of the square tube part 16, and to be long enough to be inserted into the insertion hole 22 of the frame body 23, which will be described later. . Therefore, the support rod 21
Both ends are the open ends 16a, 16 of the square tube part 16.
They will each protrude outward from b.

The frame body 23 is composed of two long side plates 24 and 25, two short side plates 26 and 27, and one frame partition plate 28, which are combined in a parallel grid shape.

The component unit 2, as shown in FIG.
Two spaces 2 separated by a frame partition plate 28
A total of four units, two units each in each of the frames 9 and 30, are housed in one frame 23. The long side plates 24 and 25 have eight pairs of through holes 2 facing each other.
2 are formed with spaces between each other.

Both ends of the support rod 21 that supports the component unit 2 can be inserted through these insertion holes 22, respectively. The spacing between the insertion holes 22 is the same as that of the support rod 2.
It is determined according to the interval of 1. That is, the positions of the insertion holes 22 are selected so that the component units 2 housed with the drain valves 11 arranged alternately can be arranged at such intervals that they do not come into contact with each other.

The support rod 21 extends perpendicularly to the long side plates 24 and 25, and its both ends are inserted into the insertion holes 22, respectively. As a result, the rectangular tube portion 16 supported by the support rod 21, and therefore the component unit 2
are fixed within the spaces 29 and 30 of the frame body 23, as shown in FIG.

When packaging the component units 2 in the box 3, four component units 2 are packaged as shown in FIG.
As shown in FIG. 2, the frames 23 containing the boxes are stacked in three tiers: upper, middle, and lower, in the left and right space partitioned by a box partition plate 50 placed at the center of the box 3. Load with. At this time, each one end of the support rod 21 protruding from the insertion hole 22 of the frame 23 is
It is loaded so that it abuts against the box partition plate 50, and each other end abuts against the inner surface of the box body 3. Since both ends of the support rod 21 are brought into contact with the box partition plate 50 and the box body 3 in this way, the support rod 21 is prevented from coming out of the insertion hole 22 of the frame body 23, and the component unit 2 The fixed state of can be stabilized.

Furthermore, since the support rods 21 are in contact with the inner walls of the side portions of the rectangular tube portion 16 of the support member 9, the support member 9 is prevented from swinging in the vertical and horizontal directions in FIG. Moreover, the open ends 16a and 16b of the square tube part 16 are connected to the long side plates 24 and 25 of the frame body 23.
Since it comes into contact with each inner side surface of , it is prevented from swinging in the front-back direction (in the direction perpendicular to the plane of the paper in FIG. 3). In this way, the component unit 2 can be kept in a stable fixed state without rattling vertically, horizontally, and frontward.

In addition, by adopting such a configuration, there is no need to use the bottom cushioning member 4, the top reinforcing member 5, the side reinforcing member 6, etc. as shown in the conventional example, so the number of parts is reduced and the packaging work is simplified. Significantly faster. Furthermore, by partitioning the box body 3 with the box partition plate 50 and storing a plurality of component units 2 therein, the storage capacity of the component units 2 can be increased and transportation costs can be reduced.

FIG. 4 is a perspective view showing an embodiment of the packaging device of the present invention.

In FIG. 4, insertion holes 22 for inserting the support rods 21 are formed in the short side plates 26, 27 and the frame partition plate 28 that constitute the cross-shaped frame 23, and the support rods 21 are inserted into the frame partitions. Insertion hole 22 of plate 28
are passed through the support rod 21, and both ends of the support rod 21 are connected to the short side plates 26,
27 through-holes 22, respectively. In both spaces 29 and 30 of the frame body 23 partitioned by the intra-frame partition plate 28, component units 2 arranged with alternate drain valves 11 are supported by support rods 21, respectively.

In this state, if the frame 23 is housed in the box 3 as in the previous embodiment, each of the component units 2 can be stably fixed. In this embodiment, since the number of support rods 21 is halved, the reduction in the number of parts becomes even more remarkable.

The material of the frame body 23 is not limited to cardboard, but may also be a synthetic resin material such as plastic.

The number of component units 2 housed in the frame body 23 and the number of frame bodies 23 are not limited to the above embodiments;
The number may be less than or equal to 5, or may be greater than or equal to 5. Further, the number of frames 23 housed in the box 3 is not limited to the above embodiments, and should be interpreted to include all numbers of 1 or 2 or more.

The packaging device according to the present invention can be used not only for parts of fully automatic electric washing machines, but also for parts of other electrical appliances.
