Description
本発明は、液体や気体といった流体を噴出（流出）するスプレーガンに関するものであり、食品機械や薬品機械といった常に洗浄を必要とする装置、機械、器具を洗浄する洗浄液の噴出用に用いて好適なスプレーガンに関するものである。 The present invention relates to a spray gun that ejects (flows out) a fluid such as a liquid or a gas, and is suitable for use in ejecting a cleaning liquid for cleaning a device, a machine, or an instrument that always needs cleaning such as a food machine or a chemical machine. It is about a special spray gun.
この種の装置、機械、器具（以下、装置類）は細菌の繁殖を極端に嫌うことから、特に、使用後は念入りに洗浄する。この洗浄は洗浄液を被洗浄物に噴出して行うが、そのためには、噴出を制御するスプレーガンを必要とする。スプレーガンによる噴出の制御は、噴射口を開閉する開閉弁を押引するものであり、これを引金の操作で行うようにしている。この引金は、特許文献１に見られるように、ピンを中心に回動可能なレバー体（引金）を一方向（多くは戻す方向）に弾性付勢して設けたものであり、引金を手で引いて噴出口を開放している。 This type of device, machine, and instrument (hereinafter referred to as “devices”) are extremely disliked to the growth of bacteria, and therefore are carefully cleaned after use. This cleaning is performed by ejecting the cleaning liquid onto the object to be cleaned. For this purpose, a spray gun for controlling the ejection is required. Control of the ejection by the spray gun is performed by pushing and pulling an on-off valve that opens and closes the injection port, and this is performed by a trigger operation. As seen in Patent Document 1, this trigger is provided with a lever body (trigger) that is pivotable about a pin and elastically urged in one direction (mostly in a returning direction). Pull the gold by hand to open the spout.
これに伴い、この種の装置類を洗浄する洗浄液のスプレーガンも、使用後はスプレーガン自体を洗浄する必要がある。この洗浄を完全に行うためには、スプレーガンを分解する必要があるが、特に、引金についてはその分解が厄介である。引金を枢着するピンはスプレーガンの本体部にナット締め、ボルト締め或いはストップリングで止められているが、取り外すためには専用の工具を必要とする上に部品が細かいこともあって取外しに難渋する。加えて、取り外した部品が落下して紛失したり、装置や製造物に紛れ込むようなことがある。 Along with this, a spray gun of a cleaning liquid for cleaning this type of apparatus also needs to be cleaned after use. In order to perform this cleaning completely, it is necessary to disassemble the spray gun, but it is particularly troublesome to disassemble the trigger. The pin that pivots the trigger is fastened with a nut, bolt, or stop ring to the spray gun body, but it requires a special tool to remove it and may be removed due to small parts. It ’s difficult. In addition, the removed parts may fall and be lost, or get lost in the device or product.
このため、引金については分解しないで洗浄することがある。そうすると、引金と本体部との隙間に汚れが溜まり、細菌が繁殖することがある。引金までを分解して洗浄するためには、引金の取外しが容易であることはもちろんのこと、紛失や紛れ込みの虞がある細かな部品に分離しないことである。先の特許文献１にも、分解が容易なスプレーガンが提案されているが、この先行例のものは、スプレーガンの噴出口部分を迅速に分解できるものであって、引金の分解については触れられておらず、従来どおりと推察される。 For this reason, the trigger may be cleaned without being disassembled. Then, dirt may accumulate in the gap between the trigger and the main body, and bacteria may propagate. In order to disassemble and clean the trigger, it is not only easy to remove the trigger but also to not separate it into fine parts that may be lost or plugged in. A spray gun that can be easily disassembled has also been proposed in the above-mentioned Patent Document 1, but this prior example can quickly disassemble the spray port of the spray gun. It is not touched and is assumed to be the same as before.
本発明が解決しようとする課題は、引金の分解を工具等を使用しない（工具レス）でワンタッチで取り外せること、分解した部材にピンやビスといった細かい部品が含まれないようにすることである。 The problem to be solved by the present invention is that the trigger can be disassembled with one touch without using a tool or the like (toolless), and that the disassembled member does not include fine parts such as pins and screws. .
以上の課題の下、本発明は、請求項１に記載した、本体部の内部に設けられる第１流出口を上方方向である閉塞側に弾性付勢される弁頭で閉塞する開閉弁と、係合構造によって本体部に係合され、下方回動させることで弁頭の上部を構成する弁尾を下方に押動させて第１流出口を開放して流体を流出させる引金とを有するスプレーガンにおいて、本体部にピンを一体的に設け、引金にピンを工具レスで着脱可能に収受する収受部を設けて係合構造としたことを特徴とするスプレーガンを提供したものである。 Under the above-described problems, the present invention provides an on-off valve that closes the first outlet provided in the main body portion with a valve head that is elastically urged toward the closing side in the upward direction, according to claim 1; It is engaged with the main body portion by the engaging structure, and has a trigger that causes the valve tail constituting the upper part of the valve head to be pushed downward by rotating downward to open the first outlet and flow out the fluid. In the spray gun, there is provided a spray gun characterized in that a pin is integrally provided in a main body portion, and a receiving portion for receiving the pin in a detachable manner is provided on a trigger so as to be detachable. .
また、本発明は、以上の作業箱において、請求項２に記載した、収受部が引金の所定部位に開口している導入部を有しており、導入部から収受部までのピンの取込みが引金のワンタッチ操作で行われる手段、請求項３に記載した、引金が、弁尾で押圧される作用部と、作用部の後端から斜め下方に延びる握り部とで構成される手段、請求項４に記載した、本体部に対して握り部を握り込んで第１流出口を開放したとき、握り部の当該位置を保持する止め金を本体部に設けた手段、請求項５に記載した、本体部、開閉弁及び引金がステンレスで構成される手段を提供する。 Further, according to the present invention, in the above-described work box, the receiving portion described in claim 2 has an introduction portion that opens to a predetermined portion of the trigger, and the pin is taken in from the introduction portion to the receiving portion. The means which is performed by a one-touch operation of the trigger, the means according to claim 3, wherein the trigger is composed of an action part pressed by a valve tail and a grip part extending obliquely downward from a rear end of the action part. The means according to claim 4, wherein the main body is provided with a stopper that holds the position of the grip when the first outlet is opened by grasping the grip with respect to the main body. Provided is a means in which the main body, the on-off valve and the trigger described are made of stainless steel.
請求項１の発明によると、スプレーガンは本体部と引金の二部品で着脱可能に構成されているから、引金を取り外すことで両者を細部まで洗浄できる。また、引金を係合するピンは本体部に一体的に設けられているから、落下や紛失の虞がない。さらに、本体部と引金の着脱は工具レスでできるから、簡便で即座にできる。 According to the first aspect of the present invention, the spray gun is configured to be detachable by the two parts of the main body portion and the trigger, so that both can be cleaned in detail by removing the trigger. In addition, since the pin for engaging the trigger is provided integrally with the main body, there is no risk of dropping or losing. Furthermore, since the main body part and the trigger can be attached and detached without tools, it is simple and immediate.
請求項２の構成によると、引金の着脱がワンタッチ操作でできるから、簡単で迅速である。請求項３の構成によると、引金の絞り操作が容易であり、これに伴って噴出量の細かな調整ができる。請求項４の構成によると、引金から手を離していても、噴出状態を保てる。請求項５の手段によると、錆の発生しない衛生的なものにできる。 According to the second aspect of the present invention, since the trigger can be attached and detached by a one-touch operation, it is simple and quick. According to the configuration of the third aspect, the trigger throttle operation is easy, and accordingly, the ejection amount can be finely adjusted. According to the structure of Claim 4, even if it removes a hand from a trigger, it can maintain an ejection state. According to the means of claim 5, it can be hygienic without rusting.
以下、本発明の実施の形態を図面を参照して説明する。図１及び図２はスプレーガンの断面側面図であるが、スプレーガンは、直立した本体部１と、第１本体部１の上部から斜め上方に分岐する第２本体部２とで逆くの字状に形成された本体部３、及び第１本体部１の中に上下にスライド可能に挿入されて上端が覗く開閉弁４と、開閉弁４の上方に設けられる引金５とからなる。そして、これら本体部３、開閉弁４及び引金は錆の発生しないステンレスで構成して衛生面を保っている。なお、図示は省略するが、第１本体部１の下部には洗浄液管をカプラ６で接続している。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 are cross-sectional side views of the spray gun. The spray gun is reversed between the upright main body 1 and the second main body 2 that branches obliquely upward from the top of the first main body 1. It consists of a main body 3 formed in a letter shape, an on-off valve 4 that is slidably inserted into the first main body 1 so that the upper end can be seen, and a trigger 5 provided above the on-off valve 4. And these main-body parts 3, the on-off valve 4, and a trigger are comprised with the stainless steel which does not generate | occur | produce rust, and the hygienic surface is maintained. Although not shown, a cleaning liquid pipe is connected to the lower portion of the first main body 1 by a coupler 6.
第１本体部１の内部は空洞７に形成されており、第２本体部２の下方位置辺りの空洞７の上部には径細のテーパ部を経て空洞７の径よりも小さい径のストレートな狭窄部８が形成され、狭窄部８の上方から同じく空洞９が形成された第２本体部２が分岐している。この場合の狭窄部８は第１本体部１の内部に形成された第１流出口８を構成していることになる。開閉弁４は、第１流出口８の下方に位置する弁頭１０と、第１本体部１の上方に覗く弁尾１１とを有する弁棒であり、第１本体部１の空洞７内に設けられるスプリング１２で常時上方に弾性付勢されているものである。 The inside of the first body portion 1 is formed in a cavity 7, and a straight portion having a diameter smaller than the diameter of the cavity 7 is formed on the upper portion of the cavity 7 near the lower position of the second body portion 2 through a narrow taper portion. A narrowed portion 8 is formed, and a second main body portion 2 in which a cavity 9 is similarly formed is branched from above the narrowed portion 8. The narrowed portion 8 in this case constitutes the first outlet 8 formed inside the first main body 1. The on-off valve 4 is a valve stem having a valve head 10 located below the first outlet 8 and a valve tail 11 looking into the upper part of the first main body 1, and inside the cavity 7 of the first main body 1. The spring 12 provided is always elastically urged upward.
弁頭１０は、下方から第１流出口８の径よりも大きな径を有する径大部１０ａ、第１流出口８の内周に沿うストレート部１０ｂ、ストレート部１０ｂから連続して上方が径細のテーパ部１０ｃとからなっており、径大部１０ａとストレート部１０ｂとの間に第１流出口８の径よりも大きな径を有するＯリング１３を保持しているものである。したがって、開閉弁４がスプリング１２で上方に（閉塞側に）弾発されているときには、Ｏリング１３が第１流出口８で閉塞している。 The valve head 10 has a large diameter portion 10a having a diameter larger than the diameter of the first outlet 8 from below, a straight portion 10b along the inner periphery of the first outlet 8, and the upper portion continuously from the straight portion 10b. The O-ring 13 having a diameter larger than the diameter of the first outlet 8 is held between the large-diameter portion 10a and the straight portion 10b. Therefore, the O-ring 13 is closed at the first outlet 8 when the on-off valve 4 is ejected upward (to the closing side) by the spring 12.
第２本体部２の上部にはブラケット１４が突設されており、このブラケット１４にピン１５を水平に突設してこのピン１５を回動中心として引金５が設けられている。引金５は、その裏面に開閉弁４の弁尾１１が押当している作用部１６と、作用部１６から斜め下方に延びる握り部１７とでへの字状に形成されたものである。なお、引金５のこの形態は開閉弁４の長さを調整することで設定されている。 A bracket 14 projects from the upper portion of the second main body 2, and a pin 15 is projected horizontally on the bracket 14, and a trigger 5 is provided with the pin 15 as a rotation center. The trigger 5 is formed in a U-shape with an action part 16 on which the valve tail 11 of the on-off valve 4 is pressed and a grip part 17 extending obliquely downward from the action part 16. . In addition, this form of the trigger 5 is set by adjusting the length of the on-off valve 4.
そこで、第１本体部１に対して握り部１７を手で握り込むと（絞り込むと）、作用部１６は弁尾１１を押し下げ、弁頭１０を第１流出口８から離してここを開放する。すると、第１本体部１の空洞７内の洗浄液は第２本体部２の先端に設けられた第２噴出口１８から噴出される。このことから、第２噴出口１８から噴出される洗浄液は握り部１７（引金５）の絞り量に対応するものとなり、閉塞から全開まで無断階で調整できることになる。 Therefore, when the grip portion 17 is grasped by hand with respect to the first main body portion 1 (when narrowed down), the action portion 16 pushes down the valve tail 11 and separates the valve head 10 from the first outlet 8 to open it. . Then, the cleaning liquid in the cavity 7 of the first main body 1 is ejected from the second ejection port 18 provided at the tip of the second main body 2. From this, the cleaning liquid ejected from the second ejection port 18 corresponds to the amount of restriction of the grip portion 17 (trigger 5), and can be adjusted without any steps from closing to full opening.
この場合、握り部１７の握りストロークに比べて作用部１６が弁尾１１を押し下げるストロークは小さくなっているから、弁頭１０が第１噴射口８を開放して洗浄液を流通させる量を引金５の大きなストロークで細かく調整できることになり、調整能力が高い。なお、第２噴出口１８にはノズル１９とフィルター２０とが設けられている。また、握り部１７を最大に握って目一杯の噴射状態を保つために、握り部１７をその位置で保持する止金２１が第１本体部１に設けられている。この状態にしておけば、引金５から手を離しても噴出でき、別の作業もできる。 In this case, the stroke in which the action portion 16 pushes down the valve tail 11 is smaller than the grip stroke of the grip portion 17, so that the valve head 10 opens the first injection port 8 and triggers the amount of flowing cleaning liquid. Fine adjustment is possible with a large stroke of 5, and the adjustment capability is high. A nozzle 19 and a filter 20 are provided at the second jet outlet 18. Further, in order to hold the grip portion 17 to the maximum and keep a full injection state, a stopper 21 for holding the grip portion 17 in that position is provided in the first main body portion 1. In this state, even if the hand is released from the trigger 5, it can be ejected and another work can be performed.
図３は引金５を最大に引いたときの第１流出口８と弁頭１０との関係を示す要部の断面側面図であるが、引金５を緩めたときには、弁頭９のストレート部１０ｂとテーパ部１０ｃとが第１噴射口８の中に入り込み、その下に設けられているＯリング１３が第１流出口８の入口を塞いでいる。そして、引金５を一杯に引いたときには、弁頭１０の上端が第１流出口８の入口の位置かその下方まで降下している。この場合の弁頭１０のテーパ部１０ｃは、引金５をある程度引いた場合でも、洗浄液の流量が十分に確保できるのに寄与している。 FIG. 3 is a cross-sectional side view of the main part showing the relationship between the first outlet 8 and the valve head 10 when the trigger 5 is pulled to the maximum, but when the trigger 5 is loosened, the straight of the valve head 9 is shown. The portion 10 b and the tapered portion 10 c enter the first injection port 8, and an O-ring 13 provided below the first injection port 8 blocks the inlet of the first outlet 8. When the trigger 5 is pulled fully, the upper end of the valve head 10 is lowered to the position of the inlet of the first outlet 8 or below the first outlet 8. The tapered portion 10c of the valve head 10 in this case contributes to ensuring a sufficient flow rate of the cleaning liquid even when the trigger 5 is pulled to some extent.
本発明は、ピン１５と引金５との係合構成に関するものであり、図４は第１実施例の要部の断面側面図であるが、引金５には、前端に開口し、後方に水平に延びてピン１５が通過できる高さを有する導入部２２と、導入部２２の後端から下方にピン１５全体がほぼ落ち込む（没入する）収受部２３が形成されている。したがって、引金５を本体部３に装着するには、開閉弁４を押えた状態で（作用部１６で弁尾１１を押し下げた状態で）導入部２２にピン１５を銜え込み、そのまま前方に押してピン１５が収受部２３に来た位置で押えを解くと、スプリング１２の作用でピン１５は収受部２３に入り込む。 The present invention relates to an engagement configuration between the pin 15 and the trigger 5, and FIG. 4 is a cross-sectional side view of the main part of the first embodiment. An introduction portion 22 that extends horizontally and has a height that allows the pin 15 to pass therethrough, and a receiving portion 23 in which the entire pin 15 substantially drops (is submerged) downward from the rear end of the introduction portion 22 are formed. Therefore, in order to attach the trigger 5 to the main body 3, the pin 15 is held in the introduction portion 22 while the on-off valve 4 is being pressed (when the valve tail 11 is pushed down by the action portion 16), When the presser is released at the position where the pin 15 has come to the receiving portion 23, the pin 15 enters the receiving portion 23 by the action of the spring 12.
この状態は、スプリング１２で引金５を上方に弾発した状態であるから、握り部１７を握り込んで開閉弁４を押し下げても引金５は外れることはない。図５は図１のＡ−Ａ断面図であるが、作用部１５の両側には壁２４を垂らせており、この両方の壁２４に導入部２２や収受部２３をそれぞれ形成している。したがって、ピン１５はブラケット１４から左右に突設して導入部２２や収受部２３に係合しており、壁２４はブラケット１４を挟んでいて安定が強化されている。 In this state, the trigger 5 is springed upward by the spring 12, so that the trigger 5 does not come off even if the grip 17 is held and the on-off valve 4 is pushed down. FIG. 5 is a cross-sectional view taken along the line AA of FIG. 1, and walls 24 are suspended on both sides of the action portion 15, and an introduction portion 22 and a receiving portion 23 are formed on both walls 24. Therefore, the pin 15 protrudes from the bracket 14 to the left and right and engages with the introduction portion 22 and the receiving portion 23, and the wall 24 sandwiches the bracket 14 to enhance stability.
一方、引金５を本体部２から外すときも、作用部１６を押し下げてピン１５を収受部２３から導入部２２まで浮かせてそのまま後方に滑らすと、ピン１５は導入部２２から外れて分解できる。したがって、この取付け、取外しがワンタッチによる一連の動作ででき、操作が簡単、迅速であるとともに、工具も必要としない。この場合、引金５がへの字状をしていることは、これらの操作のときに力を入り易いという効果を有している。 On the other hand, when the trigger 5 is removed from the main body 2, the pin 15 can be detached from the introduction part 22 and disassembled by pushing down the action part 16 to lift the pin 15 from the receiving part 23 to the introduction part 22 and sliding it backward. . Therefore, this attachment and detachment can be performed by a series of one-touch operations, the operation is simple and quick, and no tools are required. In this case, the fact that the trigger 5 has a U-shape has an effect that a force can be easily applied during these operations.
加えて、分解した後は、本体部３と引金５だけになり、細かいピン１５等は単独では存在しない。この点で、ピン１５は本体部３と一体成形又は溶接等で一体に成形されるのが好ましいといえる。ピン１５は本体部３に対して抜けることのない緊嵌の状態にしてもよいが、嵌合孔の中に細菌等が入り込む虞があるから、これを避けるためである（この点で、一体とはこの孔を塞ぐ意味でもある）。なお、分解した後は本体部３と引金５をそれぞれ洗浄し、洗浄後は再度組み付けることになる。 In addition, after disassembling, only the main body 3 and the trigger 5 are provided, and the fine pins 15 and the like do not exist alone. In this respect, it can be said that the pin 15 is preferably integrally formed with the main body 3 by integral molding or welding. The pin 15 may be in a tight-fitting state that does not come off from the main body 3, but this is to avoid this because there is a possibility that bacteria or the like may enter the fitting hole. Means to close this hole). In addition, after disassembling, the main body 3 and the trigger 5 are cleaned, and after cleaning, they are assembled again.
図６は本体部３（ピン１５）と引金５との係合構成の第２実施例を示す要部の断面側面図であるが、本例のものは、導入部２２と収受部２３を側面視で凹陥形状にしたものであり、上方が導入部２２、下方の凹陥底が収受部２３ということになる。引金５の装着は、導入部２２の前端をピン１５の下側にあてがい、作用部１６を弁尾１１に当てて握り部１７を下側に回動させればよく、取外しはこの逆の操作をすればよい。 FIG. 6 is a cross-sectional side view of the main part showing a second embodiment of the engagement configuration of the main body 3 (pin 15) and the trigger 5, but in this example, the introduction part 22 and the receiving part 23 are arranged. It is a concave shape in a side view, and the upper part is the introduction part 22 and the lower concave bottom is the receiving part 23. The trigger 5 can be attached by applying the front end of the introduction portion 22 to the lower side of the pin 15, contacting the action portion 16 against the valve tail 11, and rotating the grip portion 17 downward. You only have to do it.
図７は第３実施例を示す同じく要部の断面側面図であるが、本例のものは、収受部２３が存在する部分の斜め下後方に開口する導入部２２と導入部２２から斜め上方前側に延びて下方に陥没する収受部２３を設けたものである。引金５をピン１５に装着するには、作用部１６で弁尾１１を押し下げて導入部２２にピン１５を銜え込み、そのまま後方に引いて握り部１７を上方に回動させると、ピン１５は収受部２３に入り込む。また、取外しはこれと逆の操作をすることになる。 FIG. 7 is a cross-sectional side view of the main part showing the third embodiment. In this example, the introduction part 22 that opens obliquely downward and rearward from the part where the receiving part 23 exists and the upper part obliquely upward from the introduction part 22 are shown. A receiving portion 23 that extends forward and sinks downward is provided. In order to attach the trigger 5 to the pin 15, the valve portion 11 is pushed down by the action portion 16, the pin 15 is held in the introduction portion 22, and pulled back as it is to rotate the grip portion 17 upward. Enters the receiving unit 23. Removal is the reverse of this operation.
これら三つの実施例に共通していることは、引金５のワンタッチ操作で着脱できることであり、これにおいて工具等を必要としない工具レスで操作できるということである。そして、このスプレーガンは食品機械等を洗浄する洗浄液に適用されることから、本体部４、開閉弁４及び引金５を始めとするすべての部材をステンレスで構成している。錆が発生せず、衛生的であるからであるが、見た目も清潔に見えるのも理由の一つである。 What is common to these three embodiments is that the trigger 5 can be attached and detached by a one-touch operation, and in this case, it can be operated without a tool or the like. And since this spray gun is applied to the washing | cleaning liquid which wash | cleans a food machine etc., all the members including the main-body part 4, the on-off valve 4, and the trigger 5 are comprised with stainless steel. This is because rust does not occur and it is hygienic, but it is also one of the reasons that it looks clean.
以上は、使用後、分解して洗浄する必要のある食品機械や薬品機械を洗浄する洗浄液のスプレーガンについてのものであるが、本発明は、これに限らない。具体的には塗装液を噴出するスプレーガンや農薬や殺虫剤を散布するスプレーガンにも適用できる。これらスプレーガンも、使用後にそのままにしておくと、固体分がこびり付いたり、次の噴射液と混ざったりする。 The above is a spray gun for a cleaning liquid for cleaning a food machine or a chemical machine that needs to be disassembled and cleaned after use, but the present invention is not limited to this. Specifically, it can be applied to a spray gun for spraying a coating liquid and a spray gun for spraying agricultural chemicals and insecticides. If these spray guns are also left as they are after use, the solid matter will stick or be mixed with the next spray liquid.
このため、洗浄することになるが、面倒なこともあって、普通は引金までは分解して洗浄しない。これらのスプレーガンでも、引金を分解して洗浄することは、その機能を保持すると同時にその周辺全体が洗浄できて好ましいのはいうまでもない。さらに、噴出するのは液体に限らず気体であってもよい。具体的には高圧空気を噴出して汚れを落としたりするスプレーガンであってもよい。 For this reason, although it will wash | clean, there is also a troublesome thing, and usually even a trigger is decomposed | disassembled and it does not wash | clean. In these spray guns, it is needless to say that it is preferable to disassemble and clean the trigger while maintaining its function and simultaneously cleaning the entire periphery. Further, the gas to be ejected is not limited to liquid but may be gas. Specifically, a spray gun that ejects high-pressure air to remove dirt may be used.
