Description

  The present invention relates to a method for joining a lead wire to each launch tube and the structure and material of a joined portion in the ignition device of continuous fireworks (referred to as smoke fire in the law).

Unlike the fireworks that shine in the night sky, the continuous fireworks are fired continuously unlike fireworks at every shot, and it is a gorgeous firework that spreads the garden in the air, so it impresses and delights the viewers. . Non-Patent Document 1 describes the outline of a method for setting up a continuous fireworks along the two ignition methods of an electric type and a conductive wire type. It is called the Starmine method, which is a mechanism that continuously launches large and small smoke fireballs and continuously blooms in the sky.

  Non-Patent Document 2 describes a starmine system using a squib wire system. In the lead-line star mine method, a large number of tubes are arranged, one or two balls are placed therein, and a number of balls are launched in sequence using the lead wire and the fast-fire wire. As shown in FIG. 1, balls are charged in the cylinder, and a lead wire called “step michi” is inserted into the cylinder from the lid of the cylinder. Since the length of this squib is changed for every cylinder, it is fired in the short order. Further, as shown in FIG. 2, since the tops of the cylinders are connected by a “quick line” (combustion speed 10 m / sec), all the cylinders are ignited almost simultaneously with a single ignition. If you want to increase the size of one star mine, or if you want to increase the launch interval in time, divide the block, and put a "connect" (conductor) between them. This is what works for more than a minute. The star mine method does not always raise the ball to the sky, but there is a method to open the ball without launching.

  FIG. 3 shows an example of the mechanism of each launch tube when connecting several launch tubes in the star mine system. To ignite the fireworks at the bottom of the launch cylinder, first ignite the upper fast firing line, and then ignite the conducting wire joined to the fast firing line at a combustion speed of 10 m / sec. Since the burning speed of the fire conductor of each launch tube is 0.01 m / sec, the timing for igniting the fireworks of the main body can be designed with the length of the fire conductor. Conventionally, when connecting the fast firing wire and the conducting wire, the fast firing wire is brought into close contact with the ignition portion of the conducting wire and fixed using a pyrotechnic called an ignition wire, and further, with a tape or the like as shown in FIG. Fix it.

  However, the conventional method has many problems. Usually, the burning speed of the fast heating line is 10 m / sec, and a large force is applied during the fast heating line combustion. In addition, some force may be applied from the outside after the fast firing wire and the conducting wire are connected. Due to these various factors, the connecting and fixing part between the fast firing wire and the conducting wire is disengaged, and as a result, ignition leakage may occur. Moreover, as shown in FIG. 5, a hole is made in the lead wire using the ignition wire and the ignition wire is attached through the hole, but the length of the lead wire may become uneven by making the hole. The burning speed of the lead wire is as slow as 0.01 m / sec, and a slight difference in distance shifts the timing of continuous launch. The beauty of the Starmine method of continuous launching is to launch it in order and in a timely manner, considering the color, shape, size and height of fireworks. If they go mad due to ignition leakage or the difference in the burning time of the lead wire, the idea of production is not interesting (Non-Patent Document 2). Therefore, the fireworkers involved in the production should pay close attention and carefully break the coating of the fast-fire wire by hand, and join it directly to the lead wire via the lead wire or ignition wire, as shown in Fig. 3. Perform the work of fixing with tape. As a result, even a skilled fireworker needs around 10 seconds / time at the joint. Also, the burning speed of the fast flame is fast, a large force is applied to the joint, the tape is not fixed, and an ignition leakage phenomenon may occur.
