Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing container for a compressor used for storing and transporting the compressor, and a packing method thereof.

[0002]

2. Description of the Related Art In recent years, the division of labor into elemental devices for industrial products has been progressing. With the progress of international division of labor, the transport and export volumes of each component are increasing. Therefore, the reliable, simple and inexpensive transportation and export of elemental equipment is
This is a very important issue.

[0003] A compressor used in an air conditioner is an important element device which is the heart of the air conditioner, and its transport volume is increasing year by year. Compressors are relatively heavy element devices and expensive devices. For this reason, it is necessary to perform reliable packing during transportation.

[0004] If a large vibration or the like occurs during transportation, the compressor is damaged. Therefore, it is desirable to pack the compressor firmly. On the other hand, the transportation cost required for transportation is generally proportional to the weight of the cargo. Therefore, it is preferable that the packing container of the compressor be lightweight. In addition, it is desirable that packing can be performed in a short time and that the package can be opened in a short time.

Conventionally, in general, a wooden frame packing container is used for packing an air conditioner as disclosed in Japanese Patent Application Laid-Open No. 6-329173, and a wooden watermark is also used for packing a compressor. A box was used. That is, a plurality of wooden flat plates are nailed and fixed at predetermined intervals to the bottom plate to which the compressor is fixed, and the flat plates are assembled in a box shape to form a packing container. In such packing, as shown in FIG. 7, the compressor (c) was housed in a wooden box so as to be aligned.

As shown in FIG. 8, in the wooden box, the bottom of the compressor (c) is placed and fixed on the upper surface of the bottom plate (b) of the wooden box. The fixing of the compressor (c) has been performed by bolting the fixture (c1) of the compressor (c) to the bottom plate (b) with the reinforcing plate (e) interposed therebetween. Bolt tightening was performed by three coaching bolts (d) arranged in an equilateral triangle so as to prevent the compressor (c) from shifting during transportation.

On the other hand, as shown in FIG. 9, the top of the compressor (c) is fixed by being pressed by a hanging bracket (h). The hanging bracket (h) is a wooden box top plate with a reinforcing member (g).
(f).

[0008] Packaging in a conventional wooden box having the above structure has been performed as follows.

First, the compressor (c) is placed on the bottom plate (b), and after sandwiching the reinforcing plate (e), the coaching bolt (d) is tightened to fix the fixture (c1) of the compressor (c). To the bottom plate (b). By such a fixing method, a predetermined number of compressors are arranged on the bottom plate (b). In the package shown in FIG. 7, 12 compressors are arranged. Then, a plurality of elongated flat plates are nailed and assembled to form side plates. Thereafter, the top plate (f) is assembled such that the hanging metal fitting (h) presses the top of the compressor (c). This top plate
(f) is formed by nailing and assembling a plurality of flat plates, similarly to the side plates.

[0010]

However, packing in a wooden box has the following problems.

[0011] Since a large number of wooden flat plates, bolts, and nails are required for packaging, the cost of the packaging container itself was high. Further, since the flat plate requires sufficient strength, the thickness of the flat plate is large, and as a result, the weight of the packing container is large. Therefore, a lot of costs were required for transportation.

Further, since bolting and nailing assembly are required, many work steps are required, and much time is required for packing work. Also, a lot of time was required when unpacking.

In addition, when bolting, a sufficient space is required for the work, so that a plurality of compressors (c) cannot be densely arranged. That is, since a certain amount of space was required between the adjacent compressors (c), the number of compressors (c) that could be stored in one wooden box was not sufficiently large.

Further, since many wooden materials (wooden flat plates) are used to make one wooden box, it goes against the need for resource saving, and requires a lot of costs for disposal, and is environmentally friendly. It was difficult to use materials in response to the problem.

The present invention has been made in view of the above points, and has as its object to reduce the weight, save resources,
