図１２は従来の流体流路の接続装置の説明図であり、少量塗料給送システム４００は、塗料カートリッジ４０１内の塗料を押出す押出し手段４０２と、塗料カートリッジ４０１の塗料吐出口に設けられた塗料カップラー４０３に塗装のために基本カップラー４０４を接続したり、基本カップラー４０４に洗浄のために洗浄カップラー４０６を接続するための接続手段４０７と、基本カップラー４０４と塗装機４０８とを連通させるための塗料配管４１１とを備える。 FIG. 8 of Patent Document 1 will be described with reference to FIG. In addition, the code | symbol was reassigned.
FIG. 12 is an explanatory diagram of a conventional fluid flow path connecting device. A small amount paint feeding system 400 is provided at an extrusion means 402 for extruding paint in a paint cartridge 401 and a paint discharge port of the paint cartridge 401. A connection means 407 for connecting the basic coupler 404 for painting to the paint coupler 403, or connecting the cleaning coupler 406 for cleaning to the basic coupler 404, and for communicating the basic coupler 404 and the coating machine 408 with each other. And a paint pipe 411.

上記の少量塗料給送システム４００の作用を次に説明する。
塗装を行うには、接続手段４０７を作動させて塗料カートリッジ４０１側の塗料カップラー４０３と基本カップラー４０４とを接続し、押出し手段４０２を作動させて、塗料カートリッジ４０１内の塗料を塗料カップラー４０３と基本カップラー４０４との接続部及び塗料配管４１１を介して塗装機４０８に供給する。これにより、塗装機４０８から塗料が噴射され、塗装が行われる。 Next, the operation of the above-described small amount paint feeding system 400 will be described.
In order to perform painting, the connecting means 407 is operated to connect the paint coupler 403 and the basic coupler 404 on the paint cartridge 401 side, and the pushing means 402 is operated to apply the paint in the paint cartridge 401 to the paint coupler 403 and the basic coupler 404. The paint is supplied to the coating machine 408 through the connection with the coupler 404 and the paint pipe 411. Thereby, a coating material is injected from the coating machine 408, and coating is performed.

また、洗浄を行うには、接続手段４０７を作動させて基本カップラー４０４と洗浄カップラー４０６とを接続し、洗浄カップラー４０６に取付けられている図示せぬ洗浄液供給手段から洗浄液を洗浄カップラー４０６と基本カップラー４０４との接続部及び塗料配管４１１を介して塗装機４０８に供給する。これにより、塗料供給経路の洗浄が行われる。   In order to perform cleaning, the connecting means 407 is operated to connect the basic coupler 404 and the cleaning coupler 406, and the cleaning liquid is supplied from the cleaning liquid supply means (not shown) attached to the cleaning coupler 406. 404 is supplied to the coating machine 408 through the connection portion 404 and the paint pipe 411. As a result, the paint supply path is cleaned.

塗装を終えた後、塗料カップラー４０３と基本カップラー４０４とを分離したときに、塗料カップラー４０３と基本カップラー４０４との接続部に溜まっていた塗料は、その量が少なければ接続部に付着したままであるが、その量が多くなると、垂れ落ちたりする不具合がある。   When the paint coupler 403 and the basic coupler 404 are separated after the painting is finished, the paint accumulated in the connection between the paint coupler 403 and the basic coupler 404 remains attached to the connection if the amount is small. There is a problem that droops when the amount increases.

基本カップラー４０４は、塗料カップラー４０３から外した後にしか洗浄カップラー４０６に接続できないから、塗料カップラー４０３と基本カップラー４０４とを分離する前に接続部を洗浄することはできない。   Since the basic coupler 404 can only be connected to the cleaning coupler 406 after being removed from the paint coupler 403, the connecting portion cannot be cleaned before the paint coupler 403 and the basic coupler 404 are separated.

また、塗料カートリッジ４０１を使用して塗装を終了した後、別の色の異なる塗料が入った塗料カートリッジに交換して塗装を行う場合、洗浄カップラー４０６に基本カップラー４０４を接続して基本カップラー４０４から塗装機４０８に至る塗料供給経路の全体を洗浄するが、例えば、同色の塗料が入った塗料カートリッジに直ちに交換して塗装を行う場合は、接続時に外気に触れて塗料が乾きやすい塗料カップラー４０３と基本カップラー４０４との接続部のみを洗浄すれば済むが、この少量塗料給送システム４００では、塗料供給経路の全体を洗浄する構造であるから、洗浄が非効率となる。
更に、洗浄するために、洗浄カップラー４０６を設置する洗浄ステーションが必要になり、装置の大型化を招く。 In addition, when the paint cartridge 401 is used to finish painting and then the paint cartridge 401 is replaced with a paint cartridge containing a paint having a different color, the basic coupler 404 is connected to the cleaning coupler 406 and the basic coupler 404 is connected. The entire paint supply route to the coating machine 408 is washed. For example, when the paint cartridge is immediately replaced with a paint cartridge containing the same color paint, the paint coupler 403 is easily dried by touching the outside air at the time of connection. Although only the connection portion with the basic coupler 404 needs to be cleaned, the small-amount paint feeding system 400 has a structure for cleaning the entire paint supply path, so that the cleaning becomes inefficient.
Furthermore, in order to perform cleaning, a cleaning station in which the cleaning coupler 406 is installed is necessary, resulting in an increase in the size of the apparatus.

本発明の目的は、塗料等の流体の垂れ落ちが防止でき、洗浄が効率良く行え、装置の小型化が図れる流体流路の接続装置を提供することにある。   An object of the present invention is to provide a fluid flow path connecting device that can prevent dripping of a fluid such as paint, can be efficiently cleaned, and can be downsized.

請求項１に係る発明は、塗料等の流体が流れる流路の接続部となる第１接続部を底面に有する雌型結合部材と、第１接続部に接続される流路の接続部となる第２接続部を先端に有する雄型結合部材とからなる流体流路の接続装置において、雌型結合部材が、底面近傍に、第１接続部及び第２接続部に洗浄用流体を供給する供給孔と、第１接続部及び第２接続部に供給された洗浄用流体を排出する排出孔とを備え、雄型結合部材が、外周部に雌型結合部材の内周面に嵌合するシール部材を備え、雌型結合部材又は雄型結合部材のどちらか一方を、シール部材が内周面に嵌合する範囲で第１接続部と第２接続部との接続状態から所定距離だけ離れた位置で停止可能な分離手段を備えることを特徴とする。   The invention according to claim 1 is a female coupling member having a first connection portion on the bottom surface as a connection portion of a flow path through which fluid such as paint flows, and a connection portion of the flow path connected to the first connection portion.

作用として、雌型結合部材及び雄型結合部材の第１接続部及び第２接続部を洗浄するには、分離手段で雌型結合部材と雄型結合部材とを所定距離だけ離し、第１接続部及び第２接続部に洗浄用流体を流す。これにより、第１接続部及び第２接続部に付着、あるいは溜まった塗料等の流体は洗浄用流体で洗い流される。従って、雌型結合部材と雄型結合部材とを、シール部材が内周面に嵌合しない位置まで分離したときに、塗料等の流体が外部へ垂れ落ちない。   As a function, in order to clean the first connecting portion and the second connecting portion of the female coupling member and the male coupling member, the first coupling is performed by separating the female coupling member and the male coupling member by a predetermined distance by the separating means. The cleaning fluid is allowed to flow through the section and the second connection section. As a result, the fluid such as paint that adheres to or accumulates on the first connection portion and the second connection portion is washed away with the cleaning fluid. Therefore, when the female coupling member and the male coupling member are separated to a position where the seal member does not fit the inner peripheral surface, fluid such as paint does not spill outside.

請求項２に係る発明は、雄型結合部材に、雌型結合部材の外周部に嵌合するガイド部を設けたことを特徴とする。
作用として、雄型結合部材のシール部材が雌型結合部材の内周面に嵌合するときに、雄型結合部材のガイド部が雌型結合部材の外周面に嵌合してシール部材の軸直角方向の位置決めが行われ、シール部材が横振れしにくくなってスムーズに雌型結合部材の内周面に嵌合する。
また、シール部材の周囲にガイド部を設けた場合、雄型結合部材のシール部材が雌型結合部材の内周面に嵌合しないときには、シール部材がガイド部によって保護される。 The invention according to claim 2 is characterized in that the male coupling member is provided with a guide portion fitted to the outer peripheral portion of the female coupling member.

Further, when the guide portion is provided around the seal member, the seal member is protected by the guide portion when the seal member of the male coupling member is not fitted to the inner peripheral surface of the female coupling member.

請求項１に係る発明では、雌型結合部材が、底面近傍に、第１接続部及び第２接続部に洗浄用流体を供給する供給孔と、第１接続部及び第２接続部に供給された洗浄用流体を排出する排出孔とを備え、雄型結合部材が、外周部に雌型結合部材の内周面に嵌合するシール部材を備え、雌型結合部材又は雄型結合部材のどちらか一方を、シール部材が内周面に嵌合する範囲で第１接続部と第２接続部との接続状態から所定距離だけ離れた位置で停止可能な分離手段を備えるので、雌型結合部材と雄型結合部材とを分離手段で所定距離だけ離し、第１接続部及び第２接続部に洗浄用流体を流すことで、洗浄用流体で第１接続部と第２接続部に付着、あるいは溜まった塗料等の流体を洗い流すことができ、第１接続部、第２接続部に塗料等の流体が固化して残留するのを防止することができる。従って、雌型結合部材と雄型結合部材とを、シール部材を内周面に嵌合しない位置まで雌型結合部材と雄型結合部材とを分離したときに、塗料等の流体が外部へ垂れ落ちるのを防止することができる。   In the invention according to claim 1, the female coupling member is supplied to the supply hole for supplying the cleaning fluid to the first connection portion and the second connection portion, and the first connection portion and the second connection portion in the vicinity of the bottom surface. The male coupling member is provided with a sealing member fitted to the inner peripheral surface of the female coupling member on the outer peripheral portion, and either the female coupling member or the male coupling member is provided. One of them is provided with separation means capable of stopping at a position separated from the connection state between the first connection portion and the second connection portion by a predetermined distance within a range in which the seal member is fitted to the inner peripheral surface. And the male coupling member are separated by a predetermined distance by a separating means, and a cleaning fluid is caused to flow through the first connection portion and the second connection portion, so that the cleaning fluid adheres to the first connection portion and the second connection portion, or The accumulated fluid such as paint can be washed away, and the fluid such as paint can be fixed to the first connection part and the second connection part. To can be prevented from remaining. Therefore, when the female coupling member and the male coupling member are separated from the female coupling member and the male coupling member to a position where the seal member is not fitted to the inner peripheral surface, fluid such as paint drips outside. It can prevent falling.

更に、第１接続部及び第２接続部のみを洗浄可能なため、洗浄用流体の使用量が少なくて済み、効率良く洗浄することができる。また更に、雌型結合部材と雄型結合部材とを所定距離だけ離した状態で洗浄できるため、特別に洗浄ステーションを設ける必要がなく、装置の小型化を図ることができる。   Furthermore, since only the first connection portion and the second connection portion can be cleaned, the amount of the cleaning fluid used is small, and the cleaning can be performed efficiently. Furthermore, since the female coupling member and the male coupling member can be cleaned in a state where they are separated from each other by a predetermined distance, it is not necessary to provide a special cleaning station, and the apparatus can be downsized.

請求項２に係る発明では、雄型結合部材に、雌型結合部材の外周面に嵌合するガイド部を設けたので、雌型結合部材と雄型結合部材とを接続するときに、ガイド部と雌型結合部材の外周面との嵌合によってシール部材が軸直角方向に位置決めされて横振れしにくくなり、シール部材を雌型結合部材の内周面にスムーズに嵌合させることができる。
また、シール部材が内周面に嵌合しない場合には、ガイド部によってシール部材を保護することができる。
以上より、シール部材の大きな摩耗や破損を防止することができる。 In the invention according to claim 2, since the male coupling member is provided with the guide portion that fits to the outer peripheral surface of the female coupling member, the guide portion is connected when the female coupling member and the male coupling member are connected. And the outer peripheral surface of the female coupling member are positioned in the direction perpendicular to the axis so that the horizontal swing is difficult, and the sealing member can be smoothly fitted to the inner peripheral surface of the female coupling member.
Further, when the seal member does not fit on the inner peripheral surface, the seal member can be protected by the guide portion.
From the above, it is possible to prevent the wear and damage of the seal member.

端部部材２２２の雌テーパ２２２ａに第３ニードルバルブ２２７の頭部２２７ａが当たり、雌テーパ２２２ｂから頭部２２７ａが離れた状態では、塗料供給通路１７は閉じ、洗浄用流体供給通路６６は開いた状態にある。なお、２２２ｃは端部部材２２２の開口である。   When the head 227a of the third needle valve 227 hits the female taper 222a of the end member 222 and the head 227a is separated from the female taper 222b, the paint supply passage 17 is closed and the cleaning fluid supply passage 66 is opened. Is in a state. Note that 222 c is an opening of the end member 222.

また、端部部材２２２の雌テーパ２２２ａから第３ニードルバルブ２２７の頭部２２７ａが離れ、雌テーパ２２２ｂに頭部２２７ａが当たった状態では、塗料供給通路１７は開き、洗浄用流体供給通路６６は閉じた状態にある。   When the head 227a of the third needle valve 227 is separated from the female taper 222a of the end member 222 and the head 227a hits the female taper 222b, the paint supply passage 17 is opened and the cleaning fluid supply passage 66 is Closed.

（ａ）において、第１バルブ装置２２を第１シリンダ装置３１で後退させ、第２バルブ装置２６を第２シリンダ装置３２で後退させた状態で、塗装カートリッジ１３を白抜き矢印で示すように下降させ、（ｂ）に示すように、塗装カートリッジ１３をカートリッジ固定部１４に載せる。 Next, the operation of the paint supply apparatus 10 described above will be described.
7 (a) to 7 (c) are operation diagrams showing how to attach the paint cartridge to the paint supply apparatus according to the present invention.
In (a), with the first valve device 22 retracted by the first cylinder device 31 and the second valve device 26 retracted by the second cylinder device 32, the coating cartridge 13 is lowered as indicated by the white arrow. The coating cartridge 13 is placed on the cartridge fixing portion 14 as shown in FIG.

（ｃ）において、白抜き矢印で示すように、第１バルブ装置２２及び第２バルブ装置２６を、それぞれ第１シリンダ装置３１、第２シリンダ装置３２で前進させ、塗装カートリッジ１３に接続する。これで塗料供給装置１０における塗料カートリッジ１３の装着が完了する。   In (c), as indicated by the white arrow, the first valve device 22 and the second valve device 26 are advanced by the first cylinder device 31 and the second cylinder device 32, respectively, and connected to the coating cartridge 13. This completes the mounting of the paint cartridge 13 in the paint supply apparatus 10.

図８は本発明に係る塗料供給装置の塗料供給の作用を示す作用図である。
流体２３を、流体供給部２８Ａから第２バルブ装置２６を介して塗料カートリッジ１３の第１室４７に供給すると、第１室４７内の圧力が高まり、フリーピストン４６が白抜き矢印で示すように図の左方に移動するため、第２室４８内の塗料１２は押し出され、矢印で示すように、塗料供給通路１７を通じて塗装ガン１６に至り、塗装ガン１６から噴射される。 FIG. 8 is an operation diagram showing the operation of supplying paint by the paint supply apparatus according to the present invention.
When the fluid 23 is supplied from the fluid supply unit 28A to the first chamber 47 of the paint cartridge 13 via the second valve device 26, the pressure in the first chamber 47 increases, and the free piston 46 is indicated by a white arrow. Since it moves to the left in the figure, the paint 12 in the second chamber 48 is pushed out, reaches the paint gun 16 through the paint supply passage 17 and is sprayed from the paint gun 16 as indicated by an arrow.

図９（ａ），（ｂ）は本発明に係る第１バルブ装置と塗料カートリッジとの接続部の洗浄の要領を示す作用図である。
（ａ）において、第３シリンダ装置３３を作動させ、第３ロッド３３ｃを白抜き矢印で示すように進出させ、第３ロッド３３ｃの先端をストッパ７７に当て、更に進出させる。 FIGS. 9 (a) and 9 (b) are operational views showing a procedure for cleaning the connecting portion between the first valve device and the paint cartridge according to the present invention.
In (a), the third cylinder device 33 is operated, the third rod 33c is advanced as indicated by a white arrow, the tip of the third rod 33c is applied to the stopper 77, and further advanced.

この結果、白抜き矢印で示すように第１連結部６８の連結部本体７１が図の左方に移動する。
図中のＳＴは第３ロッド３３ｃの全ストローク量であり、全ストローク量ＳＴは、第３ロッド３３ｃが進出する前の第３ロッド３３ｃの先端とストッパ７７とのクリアランスＣと、第３ロッド３３ｃの先端がストッパに当たった後のストローク量αとの和である。 As a result, the connecting portion main body 71 of the first connecting portion 68 moves to the left in the drawing as indicated by the white arrow.
ST in the figure is the total stroke amount of the third rod 33c, and the total stroke amount ST is the clearance C between the tip of the third rod 33c and the stopper 77 before the third rod 33c advances, and the third rod 33c. Is the sum of the stroke amount α after the tip of the contact with the stopper.

（ｂ）において、連結部本体７１の移動に伴って、白抜き矢印で示すように、第１バルブ装置２２が図の左方に移動する。この結果、図３（ｃ）で説明したのと同様に、塗料通路バルブ５３側の接続部５２Ａと第１バルブ１８側の接続部１７Ａとの間に空間１１５が形成される。図中のＣＬは接続部５２Ａと接続部１７ＡとのクリアランスＣＬ（即ち、バルブシート１２１，１７１間のクリアランスＬである。）であり、前述のストローク量αに等しい。   In (b), with the movement of the connecting portion main body 71, the first valve device 22 moves to the left in the figure as indicated by the white arrow. As a result, a space 115 is formed between the connecting portion 52A on the paint passage valve 53 side and the connecting portion 17A on the first valve 18 side, as described with reference to FIG. CL in the figure is a clearance CL between the connecting portion 52A and the connecting portion 17A (that is, the clearance L between the valve seats 121 and 171), and is equal to the stroke amount α described above.

次に、洗浄用流体を、洗浄用流体供給部７８から矢印で示すように洗浄用流体供給通路６５を介して空間１１５内に流し、洗浄用流体で空間１１５内を洗浄し、洗浄に使用された洗浄用流体は、矢印で示すように、洗浄用流体排出通路６７を介して洗浄用流体タンク８３に流れて溜まる。   Next, a cleaning fluid is allowed to flow from the cleaning fluid supply section 78 into the space 115 through the cleaning fluid supply passage 65 as indicated by an arrow, and the space 115 is cleaned with the cleaning fluid and used for cleaning. The cleaning fluid flows and accumulates in the cleaning fluid tank 83 via the cleaning fluid discharge passage 67 as indicated by an arrow.

図１０は本発明に係る塗料供給通路１７の洗浄要領を示す作用図である。
塗料通路バルブ５３と第１バルブ１８との間に空間１１５（図９（ｂ）参照）を形成した状態で、第１バルブ１８、第２バルブ２１をそれぞれ開けて、洗浄用流体を、洗浄用流体供給部７８から洗浄用流体供給通路６５、空間１１５、第１バルブ１８、第２バルブ２１に流し、更に塗装ガン１６まで流して塗料供給通路１７を洗浄する。 FIG. 10 is an operation diagram showing the cleaning procedure of the paint supply passage 17 according to the present invention.
With the space 115 (see FIG. 9B) formed between the paint passage valve 53 and the first valve 18, the first valve 18 and the second valve 21 are opened, and the cleaning fluid is used for cleaning. The fluid supply section 78 flows to the cleaning fluid supply passage 65, the space 115, the first valve 18 and the second valve 21, and further flows to the coating gun 16 to clean the coating material supply passage 17.

また、塗料供給通路１７の別の洗浄要領を次に説明する。
図１において、洗浄用流体を、洗浄用流体供給部７８から洗浄用流体供給通路８１，９１，６６に順に流し、図５において、第２バルブ２１内のバルブ内洗浄流体通路２５４，２５３、バルブ室２５１、バルブ内塗料通路２５２に順に流し、更に塗装ガン１６まで流して塗料供給通路１７を洗浄する。 Further, another cleaning procedure for the paint supply passage 17 will be described below.
In FIG. 1, the cleaning fluid flows from the cleaning fluid supply unit 78 to the cleaning fluid supply passages 81, 91, 66 in order, and in FIG. 5, the cleaning fluid passages 254, 253 in the second valve 21, The paint is supplied to the chamber 251 and the paint passage 252 in the valve in order, and further to the paint gun 16 to clean the paint supply passage 17.

以上の図１〜図３で説明したように、塗料カートリッジ１３側の塗料通路５２と第１バルブ装置２２側の塗料供給通路１７とを接続する接続装置１１８を設けたことで、雌型結合部材１１２と雄型結合部材１１１とを分離手段としての分離装置１０７で所定クリアランスＣＬだけ離し、第１接続部としての接続部１７Ａ及び第２接続部としての接続部５２Ａに洗浄用流体を流すことで、洗浄用流体で接続部１７Ａと接続部５２Ａに付着、あるいは溜まった塗料１２を洗い流すことができ、接続部１７Ａ、接続部５２Ａに塗料１２が固化して残留するのを防止することができる。従って、雌型結合部材１１２と雄型結合部材１１１とを、シール部材としてのシール組立体１１４を雌型結合部材１１２の内周面に嵌合しない位置まで雌型結合部材１１２と雄型結合部材１１１とを分離したときに、塗料１２が外部へ垂れ落ちるのを防止することができる。   As described above with reference to FIGS. 1 to 3, by providing the connection device 118 that connects the paint passage 52 on the paint cartridge 13 side and the paint supply passage 17 on the first valve device 22 side, a female coupling member is provided. 112 and the male coupling member 111 are separated by a predetermined clearance CL by a separating device 107 as a separating means, and a cleaning fluid is caused to flow through the connecting portion 17A as the first connecting portion and the connecting portion 52A as the second connecting portion. The paint 12 adhered to or accumulated in the connection portion 17A and the connection portion 52A can be washed away with the cleaning fluid, and the paint 12 can be prevented from solidifying and remaining in the connection portion 17A and the connection portion 52A. Therefore, the female coupling member 112 and the male coupling member 111, and the female coupling member 112 and the male coupling member up to a position where the seal assembly 114 as a sealing member is not fitted to the inner peripheral surface of the female coupling member 112. It is possible to prevent the paint 12 from dripping to the outside when 111 is separated.

更に、接続部１７Ａ及び接続部５２Ａのみを洗浄可能なため、洗浄用流体の使用量が少なくて済み、効率良く洗浄することができる。また更に、雌型結合部材１１２と雄型結合部材１１１とを所定クリアランスＣＬだけ離した状態で洗浄できるため、特別に洗浄ステーションを設ける必要がなく、装置の小型化を図ることができる。   Furthermore, since only the connecting portion 17A and the connecting portion 52A can be cleaned, the amount of cleaning fluid used can be reduced and cleaning can be performed efficiently. Furthermore, since the female coupling member 112 and the male coupling member 111 can be cleaned while being separated by a predetermined clearance CL, there is no need to provide a special cleaning station, and the apparatus can be miniaturized.

図１１（ａ）〜（ｃ）は本発明に係る塗料カートリッジと第１バルブ装置との接続部の構造の別実施形態とその作用を示す概略図である。図３（ａ）〜（ｃ）に示した実施形態と同一構成については同一符号を付け、詳細説明は省略する。
（ａ）において、塗料カートリッジ２７０は、雄型結合部材１１１と、この雄型結合部材１１１の周囲を覆うように突出させた筒状のガイド部２７１とを備え、第１バルブ装置２７５は、雌型結合部材１１２と、この雌型結合部材１１２の外周部に取付けられた筒状の被ガイド部２７６とを備え、被ガイド部２７６がガイド部２７１にガイドされて嵌合するように形成され、雄型結合部材１１１と雌型結合部材１１２が嵌合可能に形成されている。 FIGS. 11A to 11C are schematic views showing another embodiment of the structure of the connecting portion between the paint cartridge and the first valve device according to the present invention and the operation thereof. The same components as those in the embodiment shown in FIGS. 3A to 3C are denoted by the same reference numerals, and detailed description thereof is omitted.
In (a), the paint cartridge 270 includes a male coupling member 111 and a cylindrical guide portion 271 that protrudes so as to cover the periphery of the male coupling member 111. The first valve device 275 includes a female A mold coupling member 112 and a cylindrical guided portion 276 attached to the outer peripheral portion of the female coupling member 112, and the guided portion 276 is guided by the guide portion 271 to be fitted thereto, The male coupling member 111 and the female coupling member 112 are formed so as to be fitted.

第１シリンダ装置３１（図１参照）を作動させて、雌型結合部材１１２を白抜き矢印のように前進させたのが（ｂ）の状態である。即ち、（ｂ）は、被ガイド部２７６がガイド部２７１にガイドされながら雌型結合部材１１２と雄型結合部材１１１とが結合し、接続部１７Ａと接続部５２Ａとが接続されて塗料カートリッジ２７０側の塗料通路５２と第１バルブ装置２７５側の塗料供給通路１７とが連通したことを示す。   In the state (b), the first cylinder device 31 (see FIG. 1) is operated to advance the female coupling member 112 as indicated by the white arrow. That is, (b) shows that the female coupling member 112 and the male coupling member 111 are coupled while the guided portion 276 is guided by the guide portion 271, and the connecting portion 17 </ b> A and the connecting portion 52 </ b> A are connected to each other. It shows that the paint passage 52 on the side communicates with the paint supply passage 17 on the first valve device 275 side.

（ｃ）は、分離装置１０７（図２参照）が作動することにより、被ガイド部２７６がガイド部２７１にガイドされながら雌型結合部材１１２が白抜き矢印で示すように（ｂ）の状態からわずかに後退し、接続部５２Ａと接続部１７Ａとの間に空間１１５が形成されたことを示す。   FIG. 2C shows the state where the female coupling member 112 is indicated by the white arrow while the guided portion 276 is guided by the guide portion 271 by the operation of the separating device 107 (see FIG. 2). It slightly recedes, indicating that a space 115 has been formed between the connecting portion 52A and the connecting portion 17A.

以上の（ａ）〜（ｃ）で説明したように、雄型結合部材１１１に、雌型結合部材１１２の外周部に嵌合するガイド部２７１を設けている。
これにより、雌型結合部材１１２と雄型結合部材１１１とを接続するときに、ガイド部２７１と雌型結合部材１１２の外周面との嵌合によってシール部材としてのシール組立体１１４が軸直角方向（雌型結合部材１１２の進行方向と直交する方向であり、例えば、図では上下方向）に位置決めされて横振れしにくくなり、シール組立体１１４を雌型結合部材１１２の内周面にスムーズに嵌合させることができる。 As described in the above (a) to (c), the male coupling member 111 is provided with the guide portion 271 that fits to the outer peripheral portion of the female coupling member 112.
Accordingly, when the female coupling member 112 and the male coupling member 111 are connected, the seal assembly 114 as a seal member is perpendicular to the axis due to the fitting between the guide portion 271 and the outer peripheral surface of the female coupling member 112. (It is a direction orthogonal to the traveling direction of the female coupling member 112, for example, in the vertical direction in the figure) and is difficult to sway, and the seal assembly 114 can be smoothly applied to the inner peripheral surface of the female coupling member 112. Can be fitted.

また、シール組立体１１４が雌型結合部材１１２の内周面に嵌合しない場合には、ガイド部２７１によってシール組立体１１４を保護することができる。
以上より、シール組立体１１４の大きな摩耗や破損を防止することができる。 Further, when the seal assembly 114 does not fit on the inner peripheral surface of the female coupling member 112, the seal assembly 114 can be protected by the guide portion 271.
From the above, it is possible to prevent the seal assembly 114 from being greatly worn or damaged.

尚、本実施形態では、図４に示したように、シール組立体１１４に２つのＯリング１５６，１５６を備えたが、これに限らず、一つのＯリング１５６のみを備えてもよい。   In the present embodiment, as shown in FIG. 4, the seal assembly 114 includes the two O-rings 156 and 156, but the present invention is not limited to this, and only one O-ring 156 may be provided.
