Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for packaging connecting nails,
More specifically, the present invention relates to a packaging method capable of packaging a wound body, in which connecting nails are formed in a spiral shape, at a constant height.

[0002]

2. Description of the Related Art A connecting nail used in an automatic nailing machine is made of a synthetic resin tape that holds a large number of nails in parallel at regular intervals and is formed into a spiral wound body. It is used for nailing while stored in the magazine of the nailer.

Conventionally, the above-mentioned method for packaging the connecting nails has been
With two wound bodies as a pair, the tips of the shafts of the nails of both wound bodies are made to face each other so that the nail shafts of both wound bodies are positioned in the space formed between the mating nail shafts. They are combined in an interlocking manner, and the combination is stored in a case for packaging in a state in which one or more of them are stacked or arranged in a plane.

[0004]

In the conventional packaging method described above, since the nail shaft portions of the wound body forming a pair are combined so as to be intermeshed with each other, the height dimension during packaging can be reduced accordingly. On the other hand, there are the problems listed below.

(I) There are many types of nails having different shaft lengths. Therefore, when the wound bodies are occluded and combined, the height varies, and the case for storing this also has a height. It is very uneconomical because many types of cases must be prepared according to the above.

(II) The nail has a sharp tip,
When the pair of wound bodies are occluded, a portion where the tip of the nail comes into contact with the tape of the other wound body is apt to occur, in which case the tape is damaged.

(III) When a plurality of wound bodies that have been occluded are arranged side by side and packed, adjacent winding bodies are free from each other.
The winding body moves in the case.

Therefore, an object of the present invention is to make it possible to make the height dimensions of the wound wound body constant even if the length dimensions of the nails are different, and to package them in a case of a constant height dimension. Another object of the present invention is to provide a method of wrapping a connecting nail that does not cause damage to the tape of the opposite winding body and that can prevent movement of the tape by arranging them in parallel.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention forms a wound body by spirally connecting a connecting nail in which a large number of nails are held in parallel by a long tape. ,
This winding body is used as one pair so that the tips of the shafts of the nails of both windings face each other, and the nail shafts of both windings are positioned in the space formed between the mating nail shafts. In the case of interlocking with each other, a structure is adopted in which a spacing member is interposed between the facing surfaces of both wound bodies.

[0010]

In the state where the tips of the shafts of the nails of the wound body forming a pair of two are faced to each other, and the spacing members are interposed between the facing surfaces of the wound bodies, the nail shafts of the both are made to contact each other. When interlocked with each other, the pair of wound bodies are assembled by sandwiching the spacing member, and the height dimension of the combined body is constant even if the length of the nail shaft is different, Even different nails can be packed in a case with a certain height.

Further, by connecting the adjacent winding bodies with the spacing member, it is possible to prevent the winding bodies arranged in a plane from moving.
