Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an igniter and an ignition method capable of igniting pyrotechnics such as black powder for launch fireworks, a squib and a fast ignition wire.

[0002]

2. Description of the Related Art Conventionally, to ignite a black powder for launch fireworks, a person throws a throwing powder called a heart powder in a launch tube that is ignited toward a black powder, or a person manually throws it at the tip of a bridge. A method has been used in which an electric ignition ball coated with an ignition charge is brought into contact with the black powder at the bottom of the launch cylinder, and electricity is applied from a remote location to ignite. Regarding ignition of pyrotechnics such as squib and fast-firing, there are roughly two methods, i.e., a person ignites by hand beside the pyrotechnic or an electric method from a remote place. Was taken.

[0003]

However, among the above-mentioned ignition methods, first of all, regarding the method of igniting with a human hand, (1) since the explosives to be ignited and the person are extremely close to each other,
There is always the risk of personal injury due to an accident. (2) For example, when throwing an ignition charge into a launch tube, a quick operation is performed so that a hand is not repelled by a ball, and a high skill is always required for an ignition method by a human hand. There were problems such as. Next, the electric ignition method has certainly succeeded in eliminating the above-mentioned disadvantage (1), but (3) in order to conduct electricity, two wires are always required, and it can be used in remote areas. And when trying to ignite a large number, the arrangement becomes complicated and extremely complicated. (4) It is vulnerable to electricity due to leakage current from electric appliances, electric current due to lightning, etc., which is affected by the weather, and restrictions on electric appliances and places. There were problems such as.

Means for Solving the Problems The inventors of the present invention have diligently studied whether many of the problems described above can be solved without contradiction, and as a result, produced an igniter in which one end of a nonel tube is coated with an ignition charge. However, it was found that these problems can be solved all at once by igniting the end opposite to the ignition charge using this igniter. Nonel tube (also called nonnel tube) is a pyrotechnic product in which explosive is applied to the inner wall of a hollow plastic tube, and when one end is ignited, it propagates the detonation at a speed of about 2000 m / s. (See page 181 of "Explosive Handbook" published by Kyoritsu Shuppan Co., Ltd. on May 20, 1987)
This nonel tube is said to be extremely safe, since the amount of explosive applied is extremely small, and shock does not leak to the outside of the plastic tube during detonation propagation.

The present invention (1) is an igniter characterized in that an ignition charge is applied to one end of a nonel tube. (2) Ignition characterized by igniting the igniting charge by opening the end of the nonel tube opposite to the igniting charge of the igniter of item 1 and igniting the end using a paper ball Method. It is about. The igniter applied to the igniter of the present invention may be any igniter commonly used in the explosive industry, but is usually a lead rhodanide igniter, an aromatic nitro compound igniter, diazo. Compound-based igniting agents, tetracene-based igniting agents, tricinate-based igniting agents, zirconium-lead-based igniting agents and the like are used. It is preferable that the amount of the ignition charge to be applied is as large as possible, but in view of economical efficiency and ignitability, the range of 3 mg to 1 g is preferable, and the range of 5 mg to 50 mg is more preferable. The applied ignition charge may be used as it is, or the periphery of the ignition charge may be further strengthened with a film of resin or the like. The end surface of the nonel tube to which the ignition charge is applied may have a degree of blockage such that the fire surface blown out from the terminal ignites the ignition. More preferably, the end faces are open. The ignition device according to the present invention can be used by detonating a Nonel tube with an electric detonator, a detonator for a gun, or the like as in the conventional method of igniting a Nonel tube. Is preferred.

The ignition method according to the present invention uses the above-described igniter to open the end of the nonel tube opposite to the ignition charge,
This is an ignition method in which the other ignition charge is ignited through the nonel tube by igniting the end portion with a paper ball. The paper ball used in the ignition method of the present invention is a wound ball,
It is for toys called flat balls or detonators. Usually, a paper ball is used in which an explosive compound containing potassium chlorate, red phosphorus, sulfur, or antimony trisulfide is applied in an amount of 0.002 g to 0.01 g on a mount, dried, and a thin paper paste is applied from above. .. ("Fireworks" 29 issued by Hitotsubashi Shobo on July 21, 1964
(See page 6 and “Industrial explosives” issued by the Japan Industrial Explosives Society on April 25, 1990, page 110) In the ignition method according to the present invention, the end of the nonel tube opposite to the ignition powder of the igniter is cut with a blade tool. It is opened by cutting with a method such as cutting and contacting the released end with the paper ball, or holding a distance of 10 cm or less, preferably 2 cm or less with an appropriate holder, and firing the paper ball by hitting etc. Then, the nonel tube is ignited by the impact of the ignited paper ball, and the ignition powder at the other end is ignited through the nonel tube, and the black powder or pyrotechnic is ignited by the ignition power of the ignition powder. In the ignition method according to the present invention, a pistol-type starter used for athletics etc. is processed by integrating a nonel tube holding tool and a hitting tool, and a nonel tube is inserted by punching a hole in front of a paper ball.
