【発明の属する技術分野】
本発明は、現金収納ケース、ATM装置、自動販売機等で盗難などの不慮の被害に遭遇した場合に、ケース内の紙幣束を着色インキ液等の汚濁液で使用不能状態に汚損させる汚濁液噴出装置に関する。
【0002】
【従来の技術】
この種の汚濁液噴出装置として、例えば、現金輸送用防犯ケースの内部に装備された紙幣汚損用汚濁液噴出装置が公知である(特許文献1参照。)。この汚濁液噴出装置は、着色インク等の汚濁液が加圧状態に充填されたインク収納容器に、インクを紙幣束に指向して噴出させるインク噴出装置が取り付けられる。インク噴出装置は、弁機構及び該弁機構を開放動作させる開弁機構を備えて、インク収納容器の口部にねじ込み固定されている。前記弁機構は封板、破封爪、弁軸、及びピストン等からなる弁体を備え、この弁体の入口側通路にサイホン管の基端部を、出口側通路にインク放出管の基端部をそれぞれ接続し、そのインク放出管の先端に噴射ノズルを取り付けている。前記開弁機構はインク噴出装置の弁体にこれを起動するガス発生器を備えている。起動電気信号がガス発生器に入力されると、ガス発生器が所要量のガスを発生し、そのガス圧がインク噴出装置のピストンに作用して弁軸が開弁方向に移動し、これによって弁軸先端の破封爪が封板を破って、インク収納容器内のインクがサイホン管、弁体内、インク放出管を経て汚濁液噴出ノズルから紙幣束に向けて勢いよく噴出され、紙幣が使用不能状態に汚損される。

【発明が解決しようとする課題】
しかるに、ガス発生器を用いる上記汚濁液噴出装置では構造が複雑であり、しかも非常にコスト高になるという問題があった。
また、弁機構及び開弁機構を備えたインク噴出装置がインク収納容器本体の口部にねじ込み固定される構造の上記汚濁液噴出装置では、インク収納容器としてインク噴出装置をねじ込み可能にする特殊な形状に加工する必要があり、また弁機構及び開弁機構の複雑さ、需要数量が多くない等の理由によりコスト的に高価となり、量産化も難しいものであった。これに対し、通常、市販されているエアゾール容器は、殺虫剤や化粧品等の内容物を霧状に噴出させる容器として、またスプレー式の防犯具や消火具等の容器として幅広い範囲で大量生産され、その量産化により非常に安価に入手でき、しかもそれらの多くの需要により技術レベルアップし、品質、信頼性に富むものである。
【0005】
本発明の目的は、上記のような液貯蔵容器の開弁機構を起動する起動装置にガス発生器に代えて形状記憶合金製ばねを用いることにより構造の簡素化及びコスト低減を図れる汚濁液噴出装置を提供することにある。
本発明の他の目的は、通常市販されているエアゾール容器を液貯蔵容器として使用可能になすことにより量産化、低コスト化を図れる汚濁液噴出装置を提供することにある。
【0006】
【課題を解決するための手段】
本発明の汚濁液噴出装置は、止め弁を上端口部に取り付けた液貯蔵容器、前記止め弁を開放動作させる開弁機構、該開弁機構を起動する起動装置、及び先端に汚濁液噴出ノズルを付けた配管と、を備えている。
前記液貯蔵容器の上端口部は、弁棒貫通孔を有するキャップで封口している。前記止め弁は、前記キャップの弁棒貫通孔と前記液貯蔵容器内のサイホン管の上端部とを連通状に接続した弁胴体と、この弁胴体の内部に上下方向に摺動自在に備えられかつ常に通常のばねで押上げ付勢されて前記弁棒貫通孔を閉じる弁体、及び該弁体の上端に一体形成されて前記弁棒貫通孔から上方へ突出された、液流路を有する弁棒により構成されている。
前記開弁機構は、前記キャップの上部に固定され、周壁一部に開口を有するシリンダーと、前記弁棒の上端部に結合されてこのシリンダー内を上下方向に摺動するピストンにより構成され、前記ピストンには一端開口が該ピストンの下端面に臨み他端開口が該ピストンの外周一部に臨む液流出路が形成されている。前記ピストンの液流出路の一端開口に前記弁棒の上端部が挿入結合されている。
前記配管の基端部が前記シリンダーの開口内に遊嵌状に挿通されて前記ピストンの液流出路の他端開口に一体的に結合されている。
前記起動装置は、前記シリンダー内の上蓋と前記ピストンの上端部との間に形状記憶合金製ばねを介在し、この形状記憶合金製ばねは起動電気信号に基づく通電による加熱によって伸長しこの伸長動作で前記ピストンを下降させて前記弁体を前記通常のばねの力に抗して前記弁棒貫通孔から離すことで前記弁棒の液流路が開放されて前記弁胴体内と連通するように構成している。
【0007】
この場合において、前記キャップはこれの外周縁を前記液貯蔵容器の上端口部の開口縁にかしめるとともに、該キャップの中央に前記弁棒貫通孔を有する弁蓋を膨出状に一体形成し、かつ該弁蓋の外周と前記外周縁との間に環状凹溝を形成し、前記シリンダーの下端部は前記キャップの環状凹溝に嵌合固定することができる。
【0008】
【作用】
上記構成の汚濁液噴出装置によれば、起動電気信号が形状記憶合金製ばねに通電し、形状記憶合金製ばねは電気抵抗により発熱し、この発熱により伸長する。形状記憶合金製ばねが通電加熱により伸長すると、この伸長動作がピストンに作用してピストンが下降し、これによって弁棒及び弁体が通常のばねに抗し下降して弁体が弁棒貫通孔から離されて弁棒の液流路が開放し、液貯蔵容器本体内の汚濁液がサイホン管、弁胴体内、ピストン内の液流出路、及び配管を経て汚濁液噴出ノズルに圧送されて、該噴出ノズルから紙幣束に向けて勢いよく噴出され、紙幣が使用不能状態に汚損される。
【0009】
開弁機構及びこれに取り付けられた起動装置は、開弁機構のシリンダーの下端部を液貯蔵容器のキャップの環状凹溝に嵌合固定することにより液貯蔵容器に簡単かつ確実に取り付けることができる。
【0010】
キャップ、止め弁、及びサイホン管を含む液貯蔵容器は、通常市販されているエアゾール容器の構造と全く同じ構造に構成し、その容器が持つキャップの環状凹溝を利用してこれに開弁機構のシリンダーの下端部を嵌合固定するものとしてあると、通常市販されているエアゾール容器自体に何ら改変を加えることなく、そのまま利用することができて安価で品質上信頼性に優れる汚濁液噴出装置の量産を可能にすることになる。
【0011】
【発明の実施の形態】
以下、本発明の好適な実施形態を図面に基づき説明する。図1は本発明に係る汚濁液噴出装置全体の縦断正面図、図2は汚濁液噴出装置の組付け状態の要部拡大図、図3は汚濁液噴出装置の組付け途上の状態を示す要部拡大図である。
【0012】
図1、図2において、本発明の汚濁液噴出装置は、通常市販されているエアゾール容器もしくはそれと同一構造の容器からなる、止め弁1を備えた液貯蔵容器2と、止め弁1を開放動作させる開弁機構3と、開弁機構3を起動する起動装置4、および先端に汚濁液噴出ノズル39を備えた配管40により構成される。以下、これら止め弁1、液貯蔵容器2、開弁機構3、起動装置4、配管40の各構造について詳述する。
【0013】
図3に示すように、液貯蔵容器2は、着色インク等の汚濁液と共に窒素ガス等の加圧用ガスが充填される円筒状の液貯蔵容器本体5の上端口部6の断面外巻き形状の開口縁7に、該上端口部6を封口するキャップ8の断面逆U形状の外周縁9をシール材10を介在し被せて気密状にかしめ付けている。キャップ8は中心に弁棒貫通孔11を有する弁蓋12を中央部に上向きに膨出状に形成するとともに、この弁蓋12の外周と外周縁9との間に環状凹溝13を形成している。
【0014】
キャップ8の弁蓋12には止め弁1を取り付ける。止め弁1は弁蓋12の内部に垂下状に固定された弁胴体14、弁胴体14の内部に上下方向に摺動自在にかつ通常のばね15で常に押上げ付勢された弁体16、弁体16の上端に一体に形成されて弁棒貫通孔11から上方へ突出された弁棒17により構成される。弁棒17には液流路20がこれの上端開口を弁棒17の上端面に臨ませ、下端開口を弁体16との付け根部付近に臨ませるよう軸方向に形成されている。弁蓋12の内面の弁棒貫通孔11周囲にはガスケット18により弁座19が形成され、常に押上げ付勢された弁体16はこれの上端面を弁座19に気密を保持すべく当接して弁棒貫通孔11を閉じ、これにより弁棒17の液流路20の下端開口が塞がれている。
【0015】
図1に示すように、弁胴体14の下端の液流入口21側にはサイホン管22の上端部が接続され、サイホン管22の下端部23は液貯蔵容器本体5の内方に***する断面山形状の内底面24に達して該内底面24上の周辺の最深凹部25に臨ませている。
【0016】
図2、図3に示すように、開弁機構3は、弁棒17及び弁体16をばね15に抗して押し下げて開放動作させるものであり、下端開放状のシリンダー26と、弁棒17の上端部に結合されてシリンダー26内を上下方向に摺動するピストン27により構成される。ピストン27はこれの下端面にキャップ8の中央の弁蓋12が遊嵌する凹部28を形成し、かつ一端開口29aを凹部28内に、他端開口29bをピストン外周一部にそれぞれ臨ませる液流出路29を形成している。該液流出路29の一端開口29aは弁棒17の上端部17aが挿入結合できるように形成されている。シリンダー26の開放下端寄り部にはキャップ8の外周縁9の上に座する鍔部31を張出状に形成し、この鍔部31より下方の外径部32はキャップ8の環状凹溝13に圧入により嵌合固定できる寸法、形状に形成されている。
【0017】
開弁機構3を起動する起動装置4は起動電気信号に基づく通電による加熱によって所定値以上の温度で伸長しこの伸長動作を前記ピストン27に作用させるNi−Ti合金等の形状記憶合金製ばね33により構成される。形状記憶合金製ばね33はS字形状やコイル状などに形成され、シリンダー26内の上蓋34とピストン27の上端との間に介在される。その際、形状記憶合金製ばね33はこれの上下両端部が上蓋34、ピストン27の上端部にそれぞれねじ込み固定されたボルト35,36に結合される。そして、形状記憶合金製ばね33の両端にはリード線37,38が接続され、このリード線37,38を介して起動電気信号が形状記憶合金製ばね33に通電し、形状記憶合金製ばね33は自己発熱により所定温度に達した時に記憶形状に伸長し、この伸長動作がピストン27に作用して該ピストン27が所定ストロークだけ下降するよう構成している。
【0018】
先端に汚濁液噴出ノズル39を備えた配管40はこれの基端部がシリンダー26の周壁一部に形成した開口41内に通されてピストン27の液流出路29の他端開口29bに管継手(エルボ)42を介して連通するよう一体的に結合されている。シリンダー26の開口41は、配管40がピストン27と同行するとき配管40の基端部がシリンダー26と干渉することないような融通性をもつ開口大きさに形成されている。つまり、配管40の基端部はシリンダー26の開口41内に遊嵌状に挿通されている。
【0019】
このように構成された開弁機構3及びこれに一体的に取り付けられた起動装置4を液貯蔵容器2に取り付けるには、図3の取付け前の状態から開弁機構3のピストン27の液流出路29の一端開口29a内に弁棒17の上端部を挿入結合するとともに、シリンダー26の下端部を液貯蔵容器2のキャップ8の環状凹溝13に嵌合固定することにより図2に示すごとく開弁機構3及び起動装置4は液貯蔵容器2に確実、強固に取り付けることができる。その際、キャップ8の環状凹溝13に対しシリンダー26の下端部を嵌合固定するだけでは一体結合力が不十分である場合は、図2中、仮想線Fで示すごとくシリンダー26の鍔部31周辺と液貯蔵容器本体5の開口縁7部との重合部を金属製の締結リング部材43で離脱不能に締結固定することができる。
【0020】
上記構成の汚濁液噴出装置において、起動電気信号が起動装置4の形状記憶合金製ばね33に通電すると、形状記憶合金製ばね33が伸長し、この伸長動作がピストン13に作用してピストン13が下降し、これによって弁棒17及び弁体16がばね15に抗し下降して弁体16が弁座19から離されて弁棒17の液流路20の下端開口を開放し、液貯蔵容器本体5内の汚濁液がサイホン管22、弁胴体14の液流入口21、弁棒17の液流路20、ピストン13の液流出路30、および配管40を経由して汚濁液噴出ノズル39に圧送されて、該噴出ノズル39から紙幣束等に向けて噴出させることができる。
【0021】
【発明の効果】
本発明の請求項1に記載の発明によれば、シリンダー内に、通電加熱により伸長してピストンを開弁動作させる形状記憶合金製ばねを設けるという簡単な手段で足り、従来のガス発生器を用いる汚濁液噴出装置の開弁機構に比べて構造を著しく簡単にすることができ、また安価に提供できる。
請求項2に記載の発明によれば、キャップ、止め弁、及びサイホン管を含む液貯蔵容器は、通常市販されているエアゾール容器の構造と全く同じ構造に構成しているので、その液貯蔵容器に通常市販されている安価でかつ品質、信頼性に優れるエアゾール容器を用いることができ、この点でも品質上信頼性に優れる安価な汚濁液噴出装置の量産化を実現できる。しかも、開弁機構及び起動装置はシリンダーの下端部を液貯蔵容器のキャップの環状凹溝に嵌合固定するだけの簡単な取付け手段で足り、またかかる取付け手段を採用することにより、市販エアゾール容器はこれの容量の変化にかかわらず、そのキャップ形状は同一であることから、要求される汚濁液容量に応じた市販エアゾール容器の選択が任意に行えるという利点がある。

In the contaminated liquid ejection device having the above-described configuration, when the starting electric signal is supplied to the shape memory alloy spring 33 of the starting device 4, the shape memory alloy spring 33 expands, and this extending operation acts on the piston 13 to cause the piston 13 to move. As a result, the valve stem 17 and the valve body 16 descend against the spring 15, and the valve body 16 is separated from the valve seat 19 to open the lower end opening of the liquid flow path 20 of the valve stem 17 and the liquid storage container. The contaminated liquid in the main body 5 passes through the siphon pipe 22, the liquid inlet 21 of the valve body 14, the liquid flow path 20 of the valve stem 17, the liquid outflow path 30 of the piston 13, and the pipe 40 to the contaminated liquid jet nozzle 39. It can be pressure-fed and ejected from the ejection nozzle 39 toward a bill bundle or the like.

【The invention's effect】
According to the invention described in claim 1 of the present invention, a simple means of providing a shape memory alloy spring which expands by energizing heating and opens a piston in a cylinder is sufficient. The structure can be remarkably simplified as compared with the valve opening mechanism of the polluted liquid jetting device used, and it can be provided at low cost.
According to the second aspect of the present invention, the liquid storage container including the cap, the stop valve, and the siphon tube has the same structure as that of a commercially available aerosol container. An aerosol container which is inexpensive and excellent in quality and reliability can be used, and mass production of an inexpensive contaminated liquid ejection device excellent in quality and reliability can be realized in this respect. In addition, the valve opening mechanism and the actuating device need only be a simple mounting means for fitting and fixing the lower end of the cylinder into the annular groove of the cap of the liquid storage container. Regardless of the change in the capacity, the cap shape is the same, so that there is an advantage that a commercially available aerosol container can be arbitrarily selected according to the required contaminated liquid volume.
