　本発明は、二剤型以上の組成物をスタティックミキサーで混合して吐出する組成物吐出装置に関するものである。また、本発明は該組成物吐出装置の洗浄方法に関するものである。 The present invention relates to a composition discharge device that mixes and discharges two or more types of compositions using a static mixer.

　これらは、二剤型の第一剤と第二剤を収容したタンクから夫々規定の量を計量しつつスタティックミキサーに供給し、ミキサー内でこれら二剤を混合させてノズルから接着部位に塗布するようにしている。 As a two-component composition coating apparatus, there is known a discharging device in which two components are mixed immediately before use (Patent Documents 1 to 3).

　しかしながら、上記従来例では、混合され硬化が開始された二剤がミキサー内に滞留する構成になっているために、長時間使用しない場合はミキサー内で混合された組成物が固化し、ミキサーを交換しないと塗布が再開できない不具合があった。この不具合を解消するために、ミキサー内で混合され滞留した組成物を硬化する前にミキサー内から捨て打ちさせる方法もあるが、この場合には余分な組成物を大量に消費してしまう恐れがあった。更に、スタティックミキサー内に有機溶剤を導入して洗浄する方法もあるが、多量な溶剤を必要とすることや、洗浄時後の有機溶剤の臭気、溶剤の廃棄処理方法が問題となる場合があった。 However, in the above-mentioned conventional example, since the two components that have been mixed and started to be cured are retained in the mixer, the composition mixed in the mixer is solidified when the mixture is not used for a long period of time. There was a problem that application could not be resumed without replacement. In order to solve this problem, there is a method in which the composition mixed and stayed in the mixer is thrown away from the mixer before curing, but in this case, there is a risk that a large amount of the excess composition may be consumed. there were. In addition, there is a method of introducing an organic solvent into the static mixer for cleaning, but there are cases where a large amount of solvent is required, the odor of the organic solvent after cleaning, and the disposal method of the solvent are problematic. It was.
　本発明は上述の従来技術改善を目的になされたもので、余分な材料を必要とせずにスタティックミキサー内での硬化を防止できる二剤型組成物の吐出装置を提供するものである。 The present invention has been made for the purpose of improving the above-described prior art, and provides a two-part composition discharge device that can prevent curing in a static mixer without requiring extra materials.
　上記目的を達成するため、本発明は二剤型以上の組成物をスタティックミキサーに供給して混合し塗布するための組成物吐出装置において、スタティックミキサー内に滞留した組成物を圧縮された空気のみでミキサー外へ排出させてスタティックミキサー内を洗浄し、洗浄する際に使用する空気が圧縮空気の導入ラインへ逆流しないように空気を接続する部分を逆止弁構造にした。 In order to achieve the above object, the present invention provides a composition discharging apparatus for supplying a mixture of two or more components to a static mixer, mixing and applying the composition, and the composition staying in the static mixer is only compressed air. Then, the inside of the static mixer was cleaned by discharging the air to the outside of the mixer, and a check valve structure was used to connect the air so that the air used for cleaning did not flow backward to the compressed air introduction line.
　従って、本発明は一側面において、二剤型以上の組成物を塗布するための組成物吐出装置であって、該組成物の各成分の供給路と、各成分の供給路の出口と連結したスタティックミキサーと、各成分の供給路の途中に設置されて各成分のスタティックミキサーへの導入を制御するバルブと、前記バルブの下流側で逆止弁を介して各成分の供給路にそれぞれ連結された洗浄用空気の供給路と、を備えた吐出装置である。 Accordingly, in one aspect, the present invention is a composition discharge device for applying a two-component or more composition, which is connected to each component supply path and each component supply path outlet. A static mixer, a valve installed in the middle of each component supply path to control the introduction of each component into the static mixer, and connected to each component supply path via a check valve downstream of the valve. A cleaning air supply path.
　本発明は別の一側面において、二剤型以上の組成物を塗布するための組成物吐出装置であって、該組成物の各成分の供給路と、スタティックミキサーと、各成分の供給路の出口及びスタティックミキサーの入口を連結するマニホールドと、各成分の供給路の出口に設置されて各成分のマニホールドへの導入を制御するバルブと、逆止弁を介してマニホールドに連結された成分毎の洗浄用空気の供給路と、を備えた吐出装置である。 In another aspect of the present invention, there is provided a composition discharge device for applying a two-component or more composition, comprising: a supply path for each component of the composition; a static mixer; and a supply path for each component. A manifold that connects the outlet and the inlet of the static mixer, a valve that is installed at the outlet of the supply path of each component to control the introduction of each component into the manifold, and each component that is connected to the manifold via a check valve And a cleaning air supply path.
　本発明に係る組成物吐出装置の一実施態様においては、逆止弁は、逆止弁本体と、頭部と棒部を有し逆止弁本体に収容される芯棒と、芯棒の頭部に嵌め込まれたパッキンと、芯棒の動作方向を定めるガイドと、芯棒の頭部とガイドの間の棒部の周囲に配置されたバネとを備えている。 In one embodiment of the composition discharging apparatus according to the present invention, the check valve includes a check valve body, a core rod having a head portion and a rod portion, and being accommodated in the check valve body, and a head portion of the core rod. And a guide that determines the operating direction of the core rod, and a spring disposed around the rod portion between the head portion of the core rod and the guide.
　本発明に係る組成物吐出装置の更に別の一実施態様においては、組成物が二剤型接着剤である。 In yet another embodiment of the composition discharge device according to the present invention, the composition is a two-component adhesive.
　本発明は更に別の一側面において、二剤型以上の組成物の各成分を本発明にかかる組成物吐出装置内に各成分の供給路を介して供給し、該組成物を当該組成物吐出装置からスタティックミキサーを介して吐出した後に、圧縮空気を洗浄用空気の供給路を介して本発明に係る組成物吐出装置内に供給し、スタティックミキサー内に滞留した該組成物を該圧縮空気で排出することを含む、当該組成物吐出装置の洗浄方法である。 In yet another aspect of the present invention, each component of the two-component composition or more is supplied into the composition discharge device according to the present invention via the supply path of each component, and the composition is discharged. After discharging from the apparatus through the static mixer, compressed air is supplied into the composition discharging apparatus according to the present invention via the supply path for cleaning air, and the composition staying in the static mixer is supplied with the compressed air. It is a cleaning method for the composition discharge device, including discharging.
　本発明に係る洗浄方法の一実施態様においては、すべての洗浄用空気の供給路に圧縮空気を実質的に同時に実質的に同一の圧力で供給する。 In one embodiment of the cleaning method according to the present invention, compressed air is supplied to all cleaning air supply passages at substantially the same pressure at substantially the same time.
　ここで、特許文献４には組成物と圧縮空気を同時に混ぜて発泡状態で吐出する装置が記載されているが、ミキサーや吐出ノズルの洗浄方法を記載したものでは無く、更に混合塗布装置自体に設置された逆止弁はミキサー内を洗浄する時の作用を目的として設置されたものでもない。 Here, Patent Document 4 describes a device that mixes a composition and compressed air at the same time and discharges them in a foamed state, but does not describe a method for cleaning a mixer or a discharge nozzle, and further describes a mixing and coating device itself. The installed check valve is not installed for the purpose of cleaning the inside of the mixer.
　特許文献５は圧縮された空気でミキサーや吐出ノズルを洗浄する方法が記載されているが、別途用意された専用の洗浄ガンを用いて洗浄の都度吐出ガンに接続して行うため作業性が悪い。また、洗浄に使用するのはエアフラッシュ洗浄液であるため、スタティックミキサー内の微小間隙の洗浄性が劣る。 Patent Document 5 describes a method for cleaning a mixer and a discharge nozzle with compressed air. However, workability is poor because a dedicated cleaning gun prepared separately is connected to the discharge gun each time cleaning is performed. . Moreover, since it is an air flush washing | cleaning liquid used for washing | cleaning, the washing | cleaning property of the micro gap | interval in a static mixer is inferior.
　特許文献６には、塗料供給路を洗浄するための洗浄バルブが記載されているが、洗浄バルブを逆止弁にすることについて、記載がない。特許文献６はスタティックミキサー内をエアー洗浄する際にエアー供給ラインのバルブの開閉が必要となる。本発明はエアー洗浄のためのエアー供給ラインに逆止弁を設定することにより、バルブの開閉の機構を有しなくとも、逆止弁によりエアーの加圧、減圧のみでスタティックミキサー内をエアー洗浄することが可能である。また、特許文献６では洗浄する液のキャリアーとして圧縮空気を使用するのに対し、本発明は空気のみで洗浄する点で異なる。 Patent Document 6 describes a cleaning valve for cleaning the paint supply path, but there is no description about making the cleaning valve a check valve. In Patent Document 6, it is necessary to open and close the valve of the air supply line when the inside of the static mixer is cleaned with air. In the present invention, by setting a check valve in the air supply line for air cleaning, the inside of the static mixer can be cleaned by only pressurizing and depressurizing the air with the check valve, even without a valve opening / closing mechanism. Is possible. In Patent Document 6, compressed air is used as a carrier for the liquid to be cleaned, whereas the present invention is different in that it is cleaned only with air.
　本発明は、組成物を空気のみで排出することで、スタティックミキサー内の微小間隙の洗浄性が高い。そのため、洗浄後に新たに組成物を吐出する際に、捨て打ちのための組成物の無駄を大幅に防止することができ、洗浄のための有機溶剤の必要がなくなる。 In the present invention, the fine gap in the static mixer is highly cleanable by discharging the composition only with air. Therefore, when a new composition is discharged after cleaning, waste of the composition for discarding can be largely prevented, and the need for an organic solvent for cleaning is eliminated.

（実施形態）
　図１～６に本発明を適用した二剤型組成物吐出装置の実施形態を示す。ここでは、二剤型組成物吐出装置が二剤型接着剤吐出装置であり、流体が空気である場合について説明する。 (Embodiment)
1 to 6 show an embodiment of a two-component composition discharge apparatus to which the present invention is applied. Here, a case where the two-component composition discharge device is a two-component adhesive discharge device and the fluid is air will be described.
　以下、この発明の実施例を図面に基づいて説明する。図１は二剤型組成物吐出装置の外観正面の概略図である。洗浄装置はスタティックミキサーを装着するマニホールド１と、スタティックミキサー２と、マニホールド１と連結するためのミキサーホルダー３と、組成物導入ラインにスタティックミキサー内を洗浄するために用いる圧縮された空気の逆流防止のための逆止弁４Ａ及び４Ｂと、組成物の導入を制御するバルブ５Ａ及び５Ｂから構成されている。バルブとしては逆止弁、流量調節バルブ及び開閉バルブなどが挙げられる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic front view of an external appearance of a two-component composition discharging apparatus. The cleaning device includes a manifold 1 for mounting a static mixer, a static mixer 2, a mixer holder 3 for connecting to the manifold 1, and a backflow prevention of compressed air used for cleaning the inside of the static mixer in the composition introduction line. And check valves 4A and 4B and valves 5A and 5B for controlling the introduction of the composition. Examples of the valve include a check valve, a flow rate adjustment valve, and an on-off valve.
　図面には図示していないが、二剤型組成物は各液供給装置からバルブ５Ａ及び５Ｂ通じてマニホールド１を介しスタティックミキサー２内へ供給される。二剤型組成物の吐出の制御はバルブ５Ａ及び５Ｂの開閉で行われる。 Although not shown in the drawing, the two-component composition is supplied from each liquid supply device into the static mixer 2 via the manifold 1 through the valves 5A and 5B. The discharge of the two-component composition is controlled by opening and closing the valves 5A and 5B.
　バルブ５Ａ及び５Ｂが閉じられて二剤型組成物の塗布が終了した後、スタティックミキサー２内に滞留した二剤型組成物が硬化してスタティックミキサーを閉塞するのを防止するために、逆止弁４Ａ及び４Ｂを介して、空気をスタティックミキサー２内に導入して、組成物を排出して、洗浄させる。 After the valves 5A and 5B are closed and the application of the two-component composition is completed, a check is made to prevent the two-component composition staying in the static mixer 2 from hardening and blocking the static mixer. Air is introduced into the static mixer 2 through the valves 4A and 4B, and the composition is discharged and washed.
　二剤型組成物がミキサーから吐出終了した後、スタティックミキサー２内に滞留した二剤型組成物の硬化防止のため、逆止弁を介して圧縮空気がスタティックミキサー２内へ導入される。逆止弁は二剤型組成物が吐出する時に、空気配管６内に二剤型組成物が逆流しないように作動し、空気の導入方向のみに作動するようになっている。
　流体としては、スタティックミキサー２の洗浄性の点で、空気が好ましく、圧縮空気がより好ましい。 After the two-component composition is completely discharged from the mixer, compressed air is introduced into the static mixer 2 through a check valve in order to prevent the two-component composition remaining in the static mixer 2 from hardening. The check valve operates so that the two-component composition does not flow backward into the air pipe 6 when the two-component composition is discharged, and operates only in the air introduction direction.
As the fluid, air is preferable and compressed air is more preferable from the viewpoint of detergency of the static mixer 2.
　圧縮空気の圧力は０．１ＭＰａ以上、０．６ＭＰａ以下が好ましく、スタティックミキサー２の洗浄性の点で、０．２ＭＰａ以上、０．４ＭＰａ以下がより好ましい。０．１ＭＰａ未満だと洗浄にムラが発生する恐れがある。０．６ＭＰａを超えるとスタティックミキサー２からの排出される圧縮空気の圧力が高いので周囲に危険を及ぼす恐れがある。 Compressed air pressure is preferably 0.1 MPa or more and 0.6 MPa or less, and more preferably 0.2 MPa or more and 0.4 MPa or less from the viewpoint of detergency of the static mixer 2. If it is less than 0.1 MPa, unevenness may occur in cleaning. If it exceeds 0.6 MPa, the pressure of the compressed air discharged from the static mixer 2 is high, which may cause danger to the surroundings.
　圧縮空気の圧力を調整することにより、高粘度の二剤型組成物でも迅速な空気洗浄が可能となる。圧縮空気の圧力を調整することにより、スタティックミキサー２内で二剤型組成物の硬化が進行したり、粘度が増加したりした場合にも、迅速な空気洗浄が可能となる。 By adjusting the pressure of the compressed air, it is possible to quickly clean the air even with a high viscosity two-component composition. By adjusting the pressure of the compressed air, even when the two-component composition is cured in the static mixer 2 or when the viscosity is increased, rapid air cleaning can be performed.
　逆止弁４Ａ及び４Ｂは空気を導入する空気配管６へ組成物が逆流しないようにする働きがある。圧縮空気によるスタティックミキサー２の洗浄が行われている時は、バルブ５Ａ及びバルブ５Ｂは閉じているので、二剤型組成物が導入される方向への圧縮空気の逆流はない。 The check valves 4A and 4B have a function of preventing the composition from flowing back to the air pipe 6 through which air is introduced. When the static mixer 2 is cleaned with compressed air, the valve 5A and the valve 5B are closed, so there is no backflow of compressed air in the direction in which the two-component composition is introduced.
　マニホールド１の材質としては、樹脂製や金属製等が挙げられる。耐久性、製作加工性及び外的な衝撃からの破損を防止する点で、金属製が好ましい。金属としては、加工性の点で、アルミニウムが好ましい。また、二剤型接着剤のように各成分が混合することによって硬化する組成物の場合は、マニホールド内では各成分が混合されずに、スタティックミキサーに導入された後に初めて混合が起きるように、マニホールド内では各成分が壁で仕切られていることが望ましい。マニホールド内で混合が起きると、硬化によって洗浄性が悪化したり、吐出性が低下したりするおそれがあるからである。 Examples of the material of the manifold 1 include resin and metal. Metal is preferable in terms of durability, fabrication processability, and prevention of damage from external impact. The metal is preferably aluminum from the viewpoint of workability. In addition, in the case of a composition that cures when each component is mixed, such as a two-component adhesive, the components are not mixed in the manifold, and mixing occurs only after being introduced into the static mixer. It is desirable that each component is partitioned by a wall in the manifold. This is because if the mixing occurs in the manifold, there is a possibility that the cleaning property may be deteriorated or the discharge property may be lowered due to curing.
　スタティックミキサー２は一般的なスパイラル構造やそれに準じるものであればどれでも用いることが出来る。 The static mixer 2 can use any general spiral structure or any similar one.
　ミキサーホルダー３の材質としては、樹脂製や金属製等が挙げられる。 Examples of the material of the mixer holder 3 include resin and metal.
　逆止弁４Ａ及び４Ｂは逆止弁としての制御が可能であり、気体及び液体用いずれのものでも使用できる。 The check valves 4A and 4B can be controlled as check valves, and can be used for both gas and liquid.
　組成物がミキサーから吐出終了した後、ミキサー内に滞留した組成物の硬化防止のため逆止弁を介して圧縮空気がミキサー内へ導入される。 After the composition has been discharged from the mixer, compressed air is introduced into the mixer through a check valve to prevent the composition staying in the mixer from hardening.
　逆止弁は組成物が吐出するときに、圧縮空気配管内に組成物が逆流しないように作動し、圧縮空気の導入方向のみに作動するようになっている。 The check valve operates so that the composition does not flow back into the compressed air pipe when the composition is discharged, and operates only in the direction of introducing the compressed air.
　図６は逆止弁の１種の断面図である。逆止弁４Ａ及び４Ｂは、例えば、逆止弁本体１１と、パッキン１２と、パッキン付き芯棒１３と、バネ１４と、ガイド１５から構成する。パッキン付き芯棒１３は、逆止弁本体１１内部に移動自由に収容されている。パッキン１２は、リング状である。パッキン１２は、パッキン付き芯棒１３の頭部１３Ａ側面に形成されたリング状の溝に嵌め込まれている。バネ１４は、パッキン付き芯棒１３とガイド１５との間に介装されている。バネ１４の内部は、パッキン付き芯棒１３の棒部１３Ｂが貫通している。ガイド１５は、逆止弁本体１１に螺合している。　 FIG. 6 is a cross-sectional view of one type of check valve. The check valves 4A and 4B include, for example, a check valve main body 11, a packing 12, a core rod 13 with packing, a spring 14, and a guide 15. The core rod 13 with packing is accommodated in the check valve body 11 so as to be freely movable. The packing 12 has a ring shape. The packing 12 is fitted in a ring-shaped groove formed on the side surface of the head 13A of the core rod 13 with packing. The spring 14 is interposed between the core rod 13 with packing and the guide 15. Inside the spring 14, the bar portion 13B of the core rod 13 with packing passes. The guide 15 is screwed into the check valve body 11. *
　スタティックミキサー２の洗浄時には、洗浄する際の圧縮空気がもう一方の圧縮空気導入ラインに逆流しないように圧縮空気を接続する部分に逆止弁が設置される。逆止弁は、スタティックミキサー２の装着部分であるマニホールドに逆止弁本体１１が直接接続されており、逆止弁は組成物の各成分を供給している間は閉じている。 When the static mixer 2 is washed, a check valve is installed at a portion where the compressed air is connected so that the compressed air at the time of washing does not flow back to the other compressed air introduction line. In the check valve, the check valve main body 11 is directly connected to a manifold, which is a mounting portion of the static mixer 2, and the check valve is closed while supplying each component of the composition.
　圧縮空気を導入すると、圧縮空気の圧力によりパッキン付き芯棒１３が押し上げられて、逆止弁４Ａ及び４Ｂが開く。圧縮空気の導入を停止すると、バネ１４の力により、パッキン付き芯棒１３が押し下げられて、逆止弁４Ａ及び４Ｂが閉じる。圧縮空気を導入する際は、すべての洗浄用空気の供給路に圧縮空気を実質的に同時に実質的に同一の圧力で供給することが好ましい。一部の洗浄用空気の供給路に圧縮空気を供給しない場合や、各洗浄用空気の供給路に導入する圧縮空気の圧力に極端な差が生じると、スタティックミキサー側からマニホールドに組成物又はその成分が逆流するおそれがあるからである。 When the compressed air is introduced, the core rod 13 with packing is pushed up by the pressure of the compressed air, and the check valves 4A and 4B are opened. When the introduction of the compressed air is stopped, the core rod 13 with packing is pushed down by the force of the spring 14, and the check valves 4A and 4B are closed. When the compressed air is introduced, it is preferable to supply the compressed air to all the cleaning air supply paths at substantially the same pressure at substantially the same time. When compressed air is not supplied to some cleaning air supply passages, or when there is an extreme difference in the pressure of compressed air introduced into each cleaning air supply passage, the composition or its This is because the components may flow backward.
　バルブ５Ａと５Ｂは組成物の各成分を吐出を制御できるものであればボールバルブ式やシリンダー式のいずれのものでも使用できる。 The valves 5A and 5B can be either ball valve type or cylinder type as long as the discharge of each component of the composition can be controlled.
