Description
この発明は、圧縮エアをエアガン等のエア工具に分配するエア配管に関するものである。 The present invention relates to an air pipe that distributes compressed air to an air tool such as an air gun.
エアガン等のエア工具に圧縮エアを分配するエア配管として、表面を樹脂コーティングしたアルミ製パイプを用いたものが公知である（非特許文献１）。このアルミ製パイプによれば、それまで使用していた鋼管よりもエア配管全体の重量が大幅に軽量化されるため、運搬や設置にかかる作業が楽で、工場の天井に敷設する際も天井を補強することなく、既設の天井ボード等に直接吊下することができる。また、鋼管の接続には管端をネジ加工したりネジシール材が必要となるが、上記アルミ製パイプは表面に樹脂コーティング層が形成されていることにより管端をそのままワンタッチ継手に差し込んで接続することができる。 As an air pipe for distributing compressed air to an air tool such as an air gun, an aluminum pipe whose surface is resin-coated is known (Non-Patent Document 1). According to this aluminum pipe, the weight of the entire air pipe is significantly reduced compared to the steel pipe used so far, so it is easy to carry and install, and even when laying on the factory ceiling Without being reinforced, it can be directly hung on an existing ceiling board or the like. In addition, the pipe ends are threaded or screw seals are required to connect the steel pipes, but since the aluminum pipe has a resin coating layer on the surface, the pipe ends are directly inserted into the one-touch fittings for connection. be able to.
エア配管は、管路の任意箇所を分岐して、この分岐部にエアガン等のエア工具を接続するが、圧縮エアには結露等で生じた水分が含まれており、これが圧縮エアと共にエア工具に流出すると、エア工具が故障したりワークに悪影響を及ぼす。 Air piping branches an arbitrary part of the pipeline, and an air tool such as an air gun is connected to this branch, but the compressed air contains moisture generated by condensation, etc., and this is combined with the compressed air. If it flows out, the air tool will break down or the work will be adversely affected.
特に、エア配管を水平に敷設した場合、水分は管内の底側を流れる傾向にあることから、従来は、短い鋼管を継ぎ足して、エア工具を接続する分岐部に立ち上げ配管を構成していたが、継手の数が多くなる分、施工に手間やコストがかかり、また接続不良によるエア漏出の機会も多くなる。 In particular, when the air piping is laid horizontally, moisture tends to flow on the bottom side of the pipe, so conventionally, a short steel pipe was added to configure the rising pipe at the branch part connecting the air tool. However, as the number of joints increases, the construction takes time and cost, and the opportunity for air leakage due to poor connection also increases.
一方、非特許文献１のエア配管では、管壁に横穴を開け、専用のブラケットにより前記横穴を通じて圧縮エアを取り出すようにして、エア工具側の圧縮エアに水分が混入することを防止している。しかし、管壁に横穴を設けると管の剛性が低下し、エア工具の重量や使用時の引張荷重によって管が折曲破損するおそれがある。 On the other hand, in the air piping of Non-Patent Document 1, a horizontal hole is formed in the pipe wall, and compressed air is taken out through the horizontal hole by a dedicated bracket, thereby preventing moisture from being mixed into the compressed air on the air tool side. . However, if a horizontal hole is provided in the tube wall, the stiffness of the tube is reduced, and the tube may be bent and broken due to the weight of the air tool and the tensile load during use.
本発明は上述した課題を解決するためになされたもので、その目的とするところは、施工性がよく、管の剛性を低下させることなくエア工具を接続することができるエア配管を提供することである。 The present invention has been made in order to solve the above-described problems. The object of the present invention is to provide an air pipe that has good workability and can connect an air tool without reducing the rigidity of the pipe. It is.
上述した目的を達成するために本発明では、管を無端ループ状に配設してループ配管を構築し、該ループ配管を天井に沿って水平に吊下した状態で、その管路一箇所を主幹エア管と接続すると共に、前記管路の任意箇所にエア工具が接続可能な分岐部を有するエア出力用チーズを前記分岐部を下向きに取り付けるという手段を用いる。 In order to achieve the above-described object, in the present invention, a pipe is arranged in an endless loop shape to construct a loop pipe, and in the state where the loop pipe is suspended horizontally along the ceiling, one pipe line is provided. While connecting with a main air pipe, the means of attaching the branch part to the branch for the air output cheese which has the branch part which can connect an air tool to the arbitrary places of the pipe line is used.
ここで、ループ配管の構成管として、金属と樹脂を積層した積層管を採用することで、従来の鋼管よりも配管重量を大幅に軽量化する。 Here, as a constituent pipe of the loop pipe, the weight of the pipe is significantly reduced as compared with the conventional steel pipe by adopting a laminated pipe in which a metal and a resin are laminated.
また、本発明の積層管は、曲げ形状を保持する性質、即ち可塑性を有するため、配管先の障害物を避けるように、現場で容易に曲げることができる。 Moreover, since the laminated pipe of this invention has the property which hold | maintains a bending shape, ie, plasticity, it can be bent easily on-site so that the obstruction of a piping tip may be avoided.
そして、前記エア出力用チーズは、前記分岐部とは反対側外面に前記天井への吊下部を設けるという手段を用いる。この手段により、エア工具は当該チーズを介して天井に吊持されることになるため、エア工具の重量や使用時の引張荷重によってエア配管が曲がったり、傾いたりすることがなく、さらに、ねじれ方向にも一定の強度を発揮する。 And the said cheese for air output uses the means of providing the suspending part to the said ceiling in the outer surface on the opposite side to the said branch part. By this means, the air tool is suspended from the ceiling via the cheese, so that the air pipe is not bent or tilted due to the weight of the air tool or the tensile load during use, and it is further twisted. Demonstrates a certain strength in the direction.
なお、エア出力用チーズは、分岐部に開閉弁を一体的に設けたものであることが好ましい。エア工具を別のものに付け替えたりするときなどに、エア出力を一時中断できるからである。 In addition, it is preferable that the cheese for air output is what provided the opening-and-closing valve in the branch part integrally. This is because the air output can be temporarily interrupted when the air tool is replaced with another one.
さらに、エア出力用チーズは、一次側及び二次側に管継手を設けると共に、当該継手間の流路を分岐して圧縮エアを分配する分岐部を設け、さらに、前記流路の内部に前記分岐部側から同軸上に前記流路途中まで突出する円筒状のエア流入部を設け、該エア流入部の左右に水の通路を確保してなることが好ましい。円筒状のエア流入部がチーズ内で立ち上がっているため、水分が分岐部に流出することを防止できるからである。 Furthermore, the cheese for air output is provided with a pipe joint on the primary side and the secondary side, a branch part for branching the flow path between the joints and distributing compressed air, and further, the inside of the flow path It is preferable that a cylindrical air inflow portion that protrudes from the branch portion side to the middle of the flow path is provided on the same axis, and water passages are secured on the left and right sides of the air inflow portion. This is because the cylindrical air inflow portion rises in the cheese, so that moisture can be prevented from flowing out to the branch portion.
なお、積層管は、アルミニウム製の中間層と、該中間層の内外面それぞれを被覆する樹脂製の内外層とからなる三層管であることが好ましい。金属としてアルミニウムを用いることで軽量化と可塑性が得られると共に、樹脂による内外層によって防錆作用と耐食性が得られるからである。 The laminated tube is preferably a three-layer tube comprising an aluminum intermediate layer and resin inner and outer layers covering the inner and outer surfaces of the intermediate layer. This is because weight and plasticity can be obtained by using aluminum as the metal, and rust prevention and corrosion resistance can be obtained by the inner and outer layers made of resin.
本発明によれば、エア工具を接続するエア出力部分を天井への吊下部を有するチーズによって構成したため、エア工具を接続する際に、エア配管に専用の穴を設ける必要がなく、また、エア工具の重量や使用時の引張荷重も吊下部によって天井に分散されエア配管に直接作用することがない。このため、エア配管の剛性を維持することができる。 According to the present invention, since the air output portion for connecting the air tool is constituted by the cheese having the suspended portion to the ceiling, it is not necessary to provide a dedicated hole in the air pipe when connecting the air tool, The weight of the tool and the tensile load at the time of use are also distributed to the ceiling by the suspended portion and do not act directly on the air piping. For this reason, the rigidity of air piping can be maintained.
また、エア出力用チーズは、分岐部と同軸上に内部に突出する円筒部を設けているため、圧縮エアに含まれる水分は円筒部を迂回するように流れ、該水分が分岐部から流出することを防止することができる。 In addition, since the air output cheese has a cylindrical portion that protrudes inward and coaxially with the branch portion, the moisture contained in the compressed air flows so as to bypass the cylindrical portion, and the moisture flows out from the branch portion. This can be prevented.
さらに、エア配管の管部材である積層管は、鋼管に比べて軽量であり、耐食性に優れ、しかも、現場での曲げ加工が容易であり、施工性と耐久性といった実用的効果の高いエア配管を構築することができる。 Furthermore, laminated pipes, which are pipe members of air pipes, are lighter than steel pipes, have excellent corrosion resistance, are easy to bend on site, and have high practical effects such as workability and durability. Can be built.
以下、本発明の好ましい実施の形態を添付した図面に従って説明する。図１は、本発明の一実施形態に係るエア配管を示したもので、主幹エア管１にループ配管２・３を並列に接続した例を示している。主幹エア管１はコンプレッサ等（図示せず）をエア源として、ループ配管２・３それぞれにゲートバルブを介して圧縮エア（圧縮空気）を供給している。ループ配管２・３は数本の管部材をエルボによって無端ループ状に接続したものを、天井に沿って水平に吊下している。４・・４はループ配管２・３を天井に吊下する吊バンドである。 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an air pipe according to an embodiment of the present invention, and shows an example in which loop pipes 2 and 3 are connected to a main air pipe 1 in parallel. The main air pipe 1 uses a compressor or the like (not shown) as an air source, and supplies compressed air (compressed air) to the loop pipes 2 and 3 via gate valves. The loop pipes 2 and 3 hang several pipe members connected in an endless loop shape by elbows horizontally along the ceiling. Reference numerals 4... 4 denote suspension bands that suspend the loop pipes 2 and 3 from the ceiling.
ループ配管２・３の管路中にはエア工具５・・・５を取り付けることによりエア配管を構成している。エア工具５・・５は本実施形態においてワーク清掃用のエアガンを例示している。エア工具５・・・５はコイル型のエアホース６を介してループ配管２・３に吊り下げた状態で取り付けている。エアホース６の一次側はエア出力用のチーズ７に接続している。 Air pipes are configured by attaching air tools 5... 5 in the pipe lines of the loop pipes 2 and 3. The air tools 5... 5 illustrate an air gun for cleaning a workpiece in this embodiment. The air tools 5... 5 are attached to the loop pipes 2 and 3 through coiled air hoses 6. The primary side of the air hose 6 is connected to the cheese 7 for air output.
このエア出力用チーズ７は、図２に示すように、エアホース６を接続する分岐部７ａを下向きにしてループ配管２・３に取り付けるが、本発明では、分岐部７ａと反対側外面に天井への吊下部（ブラケット部）７ｂを設けている。この吊下部７ｂを吊バンド等によって天井に固定することで、各チーズ７が天井に吊持されることになり、エア工具５の重量や使用時の引張荷重は天井に分散し、ループ配管２・３に直接作用しないようにしている。 As shown in FIG. 2, the air output cheese 7 is attached to the loop pipes 2 and 3 with the branching portion 7a connecting the air hose 6 facing downward. In the present invention, the ceiling is formed on the outer surface opposite to the branching portion 7a. Suspending portion (bracket portion) 7b is provided. Each cheese 7 is suspended from the ceiling by fixing the suspended portion 7b to the ceiling with a suspension band or the like, and the weight of the air tool 5 and the tensile load during use are dispersed on the ceiling.・ We do not act directly on 3.
また、エア出力用チーズ７は、内部構造として分岐部７ａと同軸上に円筒部７ｃを内部に向かって突設している。円筒部７ｃは上面が開口しており、この開口から圧縮エアを分岐部７ａに分岐するエア流入部として機能する。 Moreover, the cheese 7 for air output has the cylindrical part 7c protruding toward the inside coaxially with the branch part 7a as an internal structure. The cylindrical portion 7c has an open top surface, and functions as an air inflow portion that branches compressed air from the opening to the branch portion 7a.
一方、圧縮エア中に含まれる水分は円筒部７ｃに衝突し、円筒部７ｃの上面開口への侵入が阻止されている。したがって、エア工具５に水分が流出することは防止される。 On the other hand, the moisture contained in the compressed air collides with the cylindrical portion 7c and is prevented from entering the upper surface opening of the cylindrical portion 7c. Therefore, it is possible to prevent moisture from flowing out to the air tool 5.
また、図３に示すように、円筒部７ｃの左右には水Ｗの通路７ｄが形成されている。このため、円筒部７ｃの手前（一次側）で停留した水Ｗは、その水位が円筒部７ｃと同じ高さになる前に、前記通路７ｄによって円筒部７ｃを回り込むように圧縮エアと共に二次側に飛散していく。 Further, as shown in FIG. 3, water W passages 7d are formed on the left and right sides of the cylindrical portion 7c. For this reason, the water W stopped in front of the cylindrical portion 7c (primary side) is secondary together with the compressed air so as to go around the cylindrical portion 7c by the passage 7d before the water level becomes the same height as the cylindrical portion 7c. Splash to the side.
なお、ループ配管２・３には水分を排出するためのドレン部を設けることができる。 The loop pipes 2 and 3 can be provided with drain portions for discharging moisture.
エア出力用チーズ７は、分岐部７ａに開閉弁（図示せず）を一体的に設けることができる。この開閉弁によって分岐部７ａからのエア出力を開閉制御できる。したがって、エア工具５を別のものに付け替えるときに、開閉弁を閉操作することで、一時的にエア出力を調整したり停止することができる。 The air output cheese 7 can be integrally provided with an on-off valve (not shown) at the branch portion 7a. The on / off valve can control the air output from the branching portion 7a. Therefore, when changing the air tool 5 to another one, the air output can be temporarily adjusted or stopped by closing the on-off valve.
なお、エア配管の管路をループ配管２・３により構成することで、管路内のエア圧力を均等に維持でき、どの出力用チーズ７からも一定の安定した圧力のエアを分配することができる。 In addition, by configuring the pipe line of the air pipe with the loop pipes 2 and 3, the air pressure in the pipe line can be maintained evenly, and air with a constant and stable pressure can be distributed from any output cheese 7. it can.
さらに、管部材として金属（アルミ）と樹脂の積層管を用いるようにしたので、鋼管でエア配管を構築するよりも、全体重量を大幅に軽量化することができる。特に、アルミニウム製の中間層と、該中間層の内外面それぞれを被覆する樹脂製の内外層とからなる三層管を用いることで、その接続をワンタッチ接続継手で行うことができると共に、曲げ加工が容易であるので、配管作業を極めて容易に行うことができる。しかも、樹脂層をポリエチレンで構成すれば、優れた耐食性を得ることも可能である。なお、積層管における金属と樹脂の積層数は三層に限らず、二層以上であればよい。 Furthermore, since a laminated tube of metal (aluminum) and resin is used as the pipe member, the overall weight can be greatly reduced compared to constructing an air pipe with a steel pipe. In particular, by using a three-layer tube comprising an intermediate layer made of aluminum and an inner and outer layer made of resin that covers the inner and outer surfaces of the intermediate layer, the connection can be made with a one-touch connection joint, and bending is also performed. Therefore, piping work can be performed very easily. Moreover, if the resin layer is made of polyethylene, excellent corrosion resistance can be obtained. Note that the number of layers of metal and resin in the laminated tube is not limited to three layers, but may be two or more.
