Description

本発明は、船舶用信号弾等の火工品に用いる摩擦式点火具に関するものである。   The present invention relates to a friction igniter used for pyrotechnics such as a ship signal bullet.

従来、電源を使用できない状況で火工品類を点火するために種々の機械式雷管を用いた撃発方式が提案されている。一般に機械式雷管は、構造が複雑であり火工品類に一体的に組み込んだ場合、雷管に打撃等の衝撃を与えるための機構が必要である。   Conventionally, firing methods using various mechanical detonators have been proposed to ignite pyrotechnics in a situation where a power source cannot be used. In general, a mechanical detonator has a complicated structure, and when it is integrated into pyrotechnics, a mechanism for applying impact such as blow to the detonator is necessary.

また、機械式雷管を使用しない摩擦式点火具についても従来から種々提案されている。その代表例が実公昭５２−２５０９３号公報に開示された信号炎管等の点火装置である。この点火装置は、図２に示すように操作線１が小孔２を通って信号炎管容器３の内部まで延びている。内部に延びた操作線１の先端には、螺旋部４が形成されており、螺旋部４にはマッチの擦り薬５が塗布されている。また、操作線１の信号炎管容器３の外部に延びた末端は、導出部６となっている。更に、操作線１の挿通された小孔２の内側には、マッチの頭薬塊７が固着されている。信号炎管容器３の内部で螺旋部４の挿通された空間の下には、伝火薬８が設置され、更にその下層に発炎剤９が設置されている。   Various friction igniters that do not use mechanical detonators have been proposed in the past. A typical example is an ignition device such as a signal flame tube disclosed in Japanese Utility Model Publication No. 52-25093. In this ignition device, the operation line 1 extends through the small hole 2 to the inside of the signal flame tube container 3 as shown in FIG. A spiral portion 4 is formed at the tip of the operation line 1 extending inside, and a matching rubbing agent 5 is applied to the spiral portion 4. Further, the end of the operation line 1 extending outside the signal flame tube container 3 is a lead-out portion 6. Further, a matching head medicine mass 7 is fixed inside the small hole 2 through which the operation line 1 is inserted. Below the space through which the spiral portion 4 is inserted inside the signal flame tube container 3, a charge transfer agent 8 is installed, and a flame retardant 9 is installed in the lower layer.

この様に構成された信号炎管は、導出部６を引っ張ることにより点火される。導出部６が引っ張られると、マッチの擦り薬５が塗布された螺旋部４が、容器の小孔２位置に移動し、小孔２の内側に固着された頭薬塊７と接触する。その結果、擦り薬と頭薬塊との間に摩擦が生じ発火する。ここで発生した火炎が、伝火薬８を発火し、増大した火炎が発炎剤９を反応させる。
実公昭５２−２５０９３号公報 The signal flame tube configured as described above is ignited by pulling the lead-out portion 6. When the lead-out portion 6 is pulled, the spiral portion 4 to which the matching rubbing agent 5 is applied moves to the position of the small hole 2 of the container and comes into contact with the head medicine mass 7 fixed inside the small hole 2. As a result, friction is generated between the rubbing agent and the head mass, and ignition occurs. The flame generated here ignites the charge 8, and the increased flame causes the flame retardant 9 to react.
Japanese Utility Model Publication No. 52-25093

しかし、従来の機械式雷管の点火具では、部品点数が多くなり装置が複雑になると云う問題点が存在した。そのため、部品単価が高くなり、全体として製造コストが増加していた。また、実公昭５２−２５０９３号公報に開示された摩擦式点火具では、螺旋部に擦り薬を使用しないと着火信頼性に欠けると云う欠点が存在した。その対策のため、擦り薬と頭薬塊の２物品が必要となり、製造コストが高価になると云う問題があった。   However, the conventional mechanical detonator igniter has a problem that the number of parts increases and the apparatus becomes complicated. For this reason, the unit price of the parts has increased, and the manufacturing cost has increased as a whole. In addition, the friction-type igniter disclosed in Japanese Utility Model Publication No. 52-25093 has a drawback that the ignition reliability is insufficient unless a rubbing agent is used in the spiral portion. As a countermeasure, two articles, a rubbing drug and a head mass, are necessary, and there is a problem that the manufacturing cost is expensive.

The friction agent 14 contains potassium chlorate (KClO 3 ), antimony trisulfide (Sb 2 S 3 ), red phosphorus (P), commercially available shellac and ethyl alcohol as a binder, and these compounds are stirred and mixed. After applying the slurry, it is dried. The compounding ratios shown in Table 1 as Examples 1 to 15 were used. The formulation of Example 1 shown in Table 1 is potassium chlorate 40, antimony trisulfide 55, red phosphorus 5, binder 5 (parts by weight each), and the formulation of Example 2 is potassium chlorate 40, antimony trisulfide. 55, red phosphorus 4, binding agent 5 (parts by weight) and Example 3 were blended in potassium chlorate 40, antimony trisulfide 55, red phosphorus 3, binding agent 5 (parts by weight), Example 4 The formulation of potassium chlorate 40, antimony trisulfide 55, red phosphorus 2, binder 5 (each part by weight), and the formulation of Example 5 is potassium chlorate 40, antimony trisulfide 55, red phosphorus 1, viscosity Binder 5 (parts by weight), Example 6 is composed of potassium chlorate 30, antimony trisulfide 65, red phosphorus 5, binder 5 (parts by weight), and Example 7 is composed of potassium chlorate. 30, antimony trisulfide 65, red phosphorus 4 The binder 5 (each part by weight), Example 8 is composed of potassium chlorate 30, antimony trisulfide 65, red phosphorus 3, binder 5 (each part by weight), and Example 9 is composed of chloric acid. The composition of potassium 30, antimony trisulfide 65, red phosphorus 2, binding agent 5 (parts by weight) and Example 10 is potassium chlorate 30, antimony trisulfide 65, red phosphorus 1, binding agent 5 (each weight).

In addition, a resin protective film 15 is covered around the friction agent holding portion 12. The protective film 15 includes cellulose acetate, oil yellow, vinyl acetate, and acetone, and is formed by applying and drying a liquid composition in which these compounds are stirred.

次に、以上のように構成された本発明に係る摩擦式点火具１０をそれぞれの配合で、厚さ１０ｍｍで、直径１．０ｍｍの穴１７の形成されたアクリル板１８内を貫通させて着火実験を行ったところ、表１に実施例１〜１５で示すように全数着火した。点火方法は、穴１７に操作部１３を始めに通しておき、次に操作部１３を手で引っ張る。摩擦薬１４と保護膜１５が塗布された螺旋状の金属細線１１が穴１７を通過する際に摩擦が生じることにより、摩擦薬１４が発火する。摩擦薬１４が発火すると、保護膜１５も同時に燃焼する。   Next, the friction-type igniter 10 according to the present invention configured as described above is ignited by passing through the acrylic plate 18 having a thickness of 10 mm and a hole 17 having a diameter of 1.0 mm in each composition.

（比較例１）
実公昭５２‐２５０９３号公報に開示された信号炎管等の点火装置を模擬した構造を作製する為に径を変えた２つの紙筒を使用した。図３に示す様に、摩擦式点火具２０は、外径φ５．０ｍｍ、内径φ４．０ｍｍ、長さ９．０ｍｍの紙筒Ａの内側に外径φ４．０ｍｍ、内径φ３．０ｍｍ、長さ６．０ｍｍの紙筒Ｂを挿入して内側に段差部２５を製造した。当該段差部２５に表１に記載したとおりに配合した摩擦薬２２を塗布して摩擦式点火具２０を製造した。前記摩擦式点火具２０を（実施例１〜１５）同様のアクリル板の上に乗せ、摩擦薬２２に摩擦を加えるために上記と同様の金属製細線２１のみを用いて、着火確認を行ったところ１５％の確率で不発火が発生した。 (Comparative Example 1)
In order to produce a structure simulating an ignition device such as a signal flame tube disclosed in Japanese Utility Model Publication No. 52-25093, two paper tubes having different diameters were used. As shown in FIG. 3, the frictional igniter 20 has an outer diameter φ4.0 mm, an inner diameter φ3.0 mm, a length inside a paper tube A having an outer diameter φ5.0 mm, an inner diameter φ4.0 mm, and a length 9.0 mm. A 6.0 mm paper tube B was inserted to produce a step 25 on the inside. The friction igniter 20 was manufactured by applying the friction agent 22 blended as described in Table 1 to the step portion 25. The friction-type igniter 20 was placed on the same acrylic plate (Examples 1 to 15), and the ignition was confirmed using only the metal thin wire 21 similar to the above in order to apply friction to the friction agent 22. However, there was a 15% chance of non-firing.

Figure 2005155987
Figure 2005155987

そこで、実公昭５２−２５０９３号公報に開示された信号炎管等の点火装置と同様で、金属製細線２１の螺旋部２１ａに擦り薬を塗布したものを用いて着火確認を行ったところ全数発火した。このことから、実公昭５２−２５０９３号公報に開示された信号炎管等の点火装置を模擬した構造であると、摩擦を加えるために用いる金属製細線２１の螺旋部２１ａに擦り薬を塗布しないと着火信頼性が得られない。但し、擦り薬を塗布することで着火信頼性を得ることができるがその分コストが高くなると云う欠点が存在した。   Therefore, as with the ignition device such as the signal flame tube disclosed in Japanese Utility Model Publication No. 52-25093, when the ignition is confirmed using the spiral portion 21a of the metal thin wire 21 applied with a rubbing agent, all ignition is performed. did. Therefore, in the structure simulating an ignition device such as a signal flame tube disclosed in Japanese Utility Model Publication No. 52-25093, no rubbing agent is applied to the spiral portion 21a of the thin metal wire 21 used for applying friction. And ignition reliability is not obtained. However, although the reliability of ignition can be obtained by applying a rubbing agent, there is a drawback that the cost is increased accordingly.

（比較例２）
図４に示すとおり、径がφ０．５ｍｍの金属製細線２１を用いて、片側端部を曲げたものを作製した。当該曲げ部に塩素酸カリウム４０重量％、三硫化アンチモン５５重量％、粘結剤５重量％を配合した摩擦薬２２を塗布し、その上から表１に記載したとおりに配合した摩擦薬２２ａを塗布し、さらにその上から保護膜２３を塗布して摩擦式点火具２０を製造した。この摩擦式点火具２０を上記同様のアクリル板を用いて、同様の着火確認を行ったところ５％の確率で不発火が発生した。 (Comparative Example 2)
As shown in FIG. 4, a metal wire 21 having a diameter of φ0.5 mm was used to bend one end portion. A friction agent 22 containing 40% by weight of potassium chlorate, 55% by weight of antimony trisulfide, and 5% by weight of a binder is applied to the bent portion, and a friction agent 22a formulated as shown in Table 1 is applied from above. The friction igniter 20 was manufactured by applying the protective film 23 thereon. When the same ignition check was performed on this friction igniter 20 using the same acrylic plate as described above, non-ignition occurred with a probability of 5%.

このことから、（比較例２）に示す構造では着火信頼性を得ることはできない。このように実施例１〜 １５で使用した点火具の構造は着火性も確実であり摩擦式点火具として適当である。
尚、組成は塩素酸カリウム（ＫＣｌＯ3）２０〜４０重量％、三硫化アンチモン（Ｓｂ2Ｓ3）５５〜７５重量％、赤リン（Ｐ）１〜５重量％、粘結剤５重量％が好ましい。 For this reason, the ignition reliability cannot be obtained with the structure shown in (Comparative Example 2). Thus, the structure of the igniter used in Examples 1 to 15 has a reliable ignitability and is suitable as a friction igniter.
The composition is 20-40% by weight potassium chlorate (KClO 3 ), 55-75% by weight antimony trisulfide (Sb 2 S 3 ), 1-5% by weight red phosphorus (P), and 5% by weight binder. preferable.

金属製細線は求められる火炎の大きさによって金属製細線径、巻き数は任意で良い。また、金属製細線の材質については使用環境によって腐食等を考慮したものであれば良い。   The fine metal wire may have any diameter and the number of turns depending on the required flame size. The material of the metal thin wire may be any material that takes into account corrosion and the like depending on the use environment.

樹脂系保護膜は他にニトロセルース、エチルセルロース、市販のラッカーやそれらの混合物でも良い。本発明は１つの部品のみで構成され、且つ簡単な構造を有し製造性が優れているにも拘らず、着火が容易であり、摩擦薬の組成が塩素酸カリウム（ＫＣｌＯ3）、三硫化アンチモン（Ｓｂ2Ｓ3）、赤リン（Ｐ）、粘結剤であり、その上に樹脂からなる保護膜１５が被覆されている。 In addition, the resin-based protective film may be nitrocellulose, ethyl cellulose, commercially available lacquer, or a mixture thereof. Although the present invention is composed of only one part and has a simple structure and excellent manufacturability, ignition is easy and the composition of the friction agent is potassium chlorate (KClO 3 ), trisulfide. Antimony (Sb 2 S 3 ), red phosphorus (P), and a binder, and a protective film 15 made of resin is coated thereon.

なお、金属細線１１は、要求される火炎の大きさによって線径、巻き数等を任意に決めることができる。また、金属細線の材質については、使用環境によって腐蝕等を考慮して決定される。   The fine metal wire 11 can arbitrarily determine the wire diameter, the number of windings, etc. according to the required flame size. Further, the material of the fine metal wire is determined in consideration of corrosion and the like depending on the use environment.
