Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to fireworks that are launched horizontally in the sky, and particularly relates to a pair of ring star accommodation aids in which a plurality of ring stars are positioned. This is related to the fireworks built into the interior.

[Conventional technology]

Conventionally, fireworks are generally manufactured as follows.

First, multiple stars are placed one by one along the inner wall of a hemispherical casing, and then the powder is loaded into the inner space.

A firework is manufactured by joining the end faces of the pair of hemispherical casings and pasting the outer surfaces with adhesive tape or the like.

For example, in a firework that unfolds in an axial-horizontal pattern in the sky (hereinafter referred to as axial-lateral fireworks), a group of ring stars connected to each other in a ring shape (hereinafter referred to as a ring-shaped star group) is housed inside. . As a conventional example, a firework with a horizontal axis of a -ring will be described below with reference to FIG.

FIG. 4 is an exploded perspective view of a conventional single-wheel horizontal firework.

First, the powder 4, which is a powder, is wrapped in a powder exterior sheet 5 and loaded into one hemispherical casing l. Next, a plurality of connected ring stars 2 wrapped in trough-like paper pieces 11 are accommodated along the edge of the hemispherical casing 1. At this time, since the charge 4 is loaded inside the hemispherical casing 1, a plurality of ring stars 2 are placed in the gap between the charge 4 and the hemispherical casing 1 while sequentially forming depressions for the charge 4 as storage positions. We will determine the position. The end faces of the hemispherical casing 1 and the other hemispherical casing 1'' loaded with only the powder 4 were joined to produce an axis-like firework. A single toroidal ring star group is accommodated inside the axis-horizontal fireworks manufactured by the above process.

[Problem to be solved by the invention]

However, conventional horizontal axis fireworks have the following problems.

■In the process of positioning the ring stars, a plurality of ring stars are positioned while sequentially forming depressions to accommodate the ring stars in the gap between the hemispherical casing 1 and the charge 4 loaded therein. Was.

However, the positioned ring star is only loosely held in the hollow of the powder powder. Therefore, when the depression is formed and the ring star is positioned, the powder around the ring star that has already been accommodated flows, causing the ring star to shift its position. Therefore, it is necessary to position the ring stars one by one while supporting the already housed ring stars by hand, and furthermore, it is necessary to form depressions at a certain depth and at a certain interval.
The above steps were time-consuming tasks even for those with skill.

■In the process of joining the end faces of one hemispherical casing 1, which has completed the loading of the charge and the accommodation of the ring star group, to the other hemispherical casing 1, in which only the charge has been loaded, the ring star is placed in one hemisphere. Since the casing 1 is only loosely held at the edge of the casing 1 by the powder charge, it was inevitable that the rings would shift due to the stress caused by the joining.

■Since the powder charged in the hemispherical casing is a gunpowder that is relatively easy to ignite, from the standpoint of safety, a manufacturing method that would allow for gentle handling of horizontal-axis fireworks was desired.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and its object is to automatically arrange a ring star group by simply placing the ring star in the ring load positioning section in the process of positioning the ring star.
