Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging or all other reels intended to be conveniently stored and transported by winding a tape containing a large number of electronic components.

[0002]

2. Description of the Related Art A packaging reel that winds and stores a tape containing electronic components, in which two side plates are integrally fixed to both ends of a tubular core, is not wound. Since the bulk does not change even when it is not used or after use, it occupies a large space when storing or transporting electronic components before winding, which increases the cost of returning transport or storage. There is. Also, the wider the reel width, the bulkier it becomes, which is a big problem.

A foldable disposable reel has also been proposed, but since many of them use paper, there is a problem in strength, and it is not used as a large reel. In addition, there is a problem that the amount of waste increases and it takes much time to incinerate.

In order to solve the above-mentioned problems of the conventional reels, an object of the present invention is to make the reels foldable so that they do not become bulky when not in use or after use, and have sufficient strength. It is to provide a convenient reel that can be used any number of times.

When it becomes unusable, it can be melted and recycled for prevention of dust generation.

That is, since the conventional reel is basically disposable and is not intended to be reused, it is bulky and a source of a large amount of dust after use, which is a serious problem.

The present invention has been invented as a reel that can be reused and recycled without generating dust, as the global trend of environmental protection has been strengthened and the reduction of dust has been strongly demanded.

[0008] When the reel is used and sent back for reuse, the conventional reel becomes bulkier as it becomes wider and the transportation cost for return becomes higher, and even when it becomes unusable, the side plate is paper and the core fires. Since many of them are made of styrene and cannot be recycled, we had no choice but to make them into garbage.

According to the present invention, the reel can be folded and assembled freely, so that the volume is greatly reduced at the time of return and the return cost is low, and it can be easily assembled without a jig and used many times. It is possible to prevent waste of waste and also prevent generation of dust. Moreover, it is to provide a reel that can be recycled after being melted and returned to a resin even when it cannot be used.
