以下、本発明の実施の形態について添付図面を参照して説明する。本発明の第１実施形態に係る液体を吐出する装置としての印刷装置について図１ないし図３を参照して説明する。図１は同印刷装置の正面説明図、図２は同じく側面説明図、図３は同じく平面説明図である。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. A printing device as a device for discharging a liquid according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1 is a front explanatory view of the printing apparatus, FIG. 2 is a side explanatory view, and FIG. 3 is a plan explanatory view.

印刷装置１は、装置本体１００内に、被印刷部材である布地などを保持するプラテン部材３００を有するカセット２００が着脱可能であり、カセット２００を保持して進退移動するステージ１１１と、ステージ１１１で保持されたカセット２００に保持されている被印刷部材に印刷する印刷手段１１２とを備えている。 In the printing apparatus 1, a cassette 200 having a platen member 300 for holding a fabric or the like as a printing member can be attached to and detached from the apparatus main body 100, and the stage 111 and the stage 111 move forward and backward while holding the cassette 200. It is provided with a printing means 112 for printing on a member to be printed held in the held cassette 200.

ステージ１１１はスライダ部材１１３に取付けられ、スライダ部材１１３はガイド部材１１４、１１４に矢印Ｙ方向（送り方向）に往復移動可能に保持されている。スライダ部材１１３が送り方向に往復移動されることでステージ１１１が往復移動する。これにより、ステージ１１１に着脱可能に装着されたカセット２００及びカセット２００のプラテン部材３００に保持されている被印刷部材もＹ方向に往復移動する。 The stage 111 is attached to the slider member 113, and the slider member 113 is held by the guide members 114 and 114 so as to be reciprocally movable in the arrow Y direction (feeding direction). The stage 111 reciprocates as the slider member 113 reciprocates in the feed direction. As a result, the cassette 200 detachably mounted on the stage 111 and the printed member held by the platen member 300 of the cassette 200 also reciprocate in the Y direction.

印刷手段１１２は、ステージ１１１に対して矢印Ｘ方向（主走査方向）に移動するキャリッジ１２１を有し、キャリッジ１２１には液体を吐出する液体吐出手段である液体吐出ヘッド１２２を備えている。 The printing means 112 has a carriage 121 that moves in the direction of arrow X (main scanning direction) with respect to the stage 111, and the carriage 121 is provided with a liquid discharge head 122 that is a liquid discharge means for discharging liquid.

また、矢印Ｘ方向の一端部側には、キャリッジ１２１の下方に、液体吐出ヘッド１２２のメンテナンスを行うメンテナンスユニット１３０を配置している。メンテナンスユニット１３０は、液体吐出ヘッド１２２のノズル面をキャッピングするキャップ１３１などを備えている。 Further, on one end side in the direction of the arrow X, a maintenance unit 130 for maintaining the liquid discharge head 122 is arranged below the carriage 121. The maintenance unit 130 includes a cap 131 and the like for capping the nozzle surface of the liquid discharge head 122.

この印刷装置１においては、カセット２００のプラテン部材３００に被印刷部材をセットした状態で、装置本体１００内のステージ１１１にカセット２００を装着して保持する。そして、ステージ１１１の矢印Ｙ方向への移動と印刷手段１１２（キャリッジ１２１）の矢印Ｘ方向への往復移動を繰り返すことで、被印刷部材に所要の画像を印刷する。 In the printing apparatus 1, the cassette 200 is mounted and held on the stage 111 in the apparatus main body 100 in a state where the printed member is set on the platen member 300 of the cassette 200. Then, the required image is printed on the member to be printed by repeating the movement of the stage 111 in the arrow Y direction and the reciprocating movement of the printing means 112 (carriage 121) in the arrow X direction.

ここで、装置本体１００に対するカセット２００の着脱側を装置本体１００の前側とし、矢印Ｙ方向において、前側の反対側を装置本体１００の後側とする。 Here, the attachment / detachment side of the cassette 200 with respect to the apparatus main body 100 is the front side of the apparatus main body 100, and the opposite side of the front side in the arrow Y direction is the rear side of the apparatus main body 100.

そして、本実施形態の印刷装置１には、装置本体１００の両側部であって、装置本体１００の後側に、本発明に係るミスト回収装置５００、５００を配置している。 In the printing apparatus 1 of the present embodiment, the mist collecting devices 500 and 500 according to the present invention are arranged on both sides of the apparatus main body 100 and on the rear side of the apparatus main body 100.

ミスト回収装置５００は、排気ダクト５０１と、ミストを捕集するフィルタ５０２と、フィルタ５０２を通過する気流を発生させる排気ファン５０３と、第１開口部材５０４と、第２開口部材５０５とを備えている。 The mist recovery device 500 includes an exhaust duct 501, a filter 502 for collecting mist, an exhaust fan 503 for generating an air flow passing through the filter 502, a first opening member 504, and a second opening member 505. There is.

排気ダクト５０１は、カセット２００と略同じ高さで吸入口５１１を有して、吸入される空気を上方に案内する吸入ダクト部５０１ａと、吸入ダクト部５０１ａからフィルタ５０２を介して空気を吸引する排気ファン５０３が配置された中間ダクト部５０１ｂと、排気ファン５０３から送り出される空気を後方の排気口５１５に向けて案内する排出ダクト部５０１ｃとを含む。 The exhaust duct 501 has a suction port 511 at substantially the same height as the cassette 200, and sucks air from the suction duct portion 501a that guides the sucked air upward and the suction duct portion 501a via the filter 502. It includes an intermediate duct portion 501b in which the exhaust fan 503 is arranged, and an exhaust duct portion 501c that guides the air sent from the exhaust fan 503 toward the rear exhaust port 515.

ここで、排出ダクト部５０１ｃの矢印Ｙ方向における幅は、中間ダクト部５０１ｂの矢印Ｘ方向における幅よりも広くしている。 Here, the width of the discharge duct portion 501c in the arrow Y direction is wider than the width of the intermediate duct portion 501b in the arrow X direction.

排出ダクト部５０１ｃ内には、排気ファン５０３の下流側であって、排気口５１５の上流側に、排気ファン５０３側から、順次、複数の開口部材を構成する第１開口部材５０４及び第２開口部材５０５を配置している。 In the exhaust duct portion 501c, the first opening member 504 and the second opening that form a plurality of opening members sequentially from the exhaust fan 503 side on the downstream side of the exhaust fan 503 and on the upstream side of the exhaust port 515. The member 505 is arranged.

これにより、第１開口部材５０４及び第２開口部材５０５は、矢印Ｘ方向における幅を排気ファン５０３の口径よりも広くしている。つまり、排気ファン５０３は、第１開口部材５０４、第２開口部材５０５に対して偏って配置されている。 As a result, the width of the first opening member 504 and the second opening member 505 in the direction of arrow X is wider than the diameter of the exhaust fan 503. That is, the exhaust fan 503 is biased with respect to the first opening member 504 and the second opening member 505.

次に、このミスト回収装置５００が駆動されているときの空気の流れについて図４を参照して説明する。図４は同説明に供する側面説明図である。 Next, the air flow when the mist recovery device 500 is driven will be described with reference to FIG. FIG. 4 is a side explanatory view for the same explanation.

ミスト回収装置５００の排気ファン５０３を駆動することによって排気ダクト５０１の吸入口５１１から装置本体１００内の空気が吸引され、気流６００が生じる。気流６００は、キャリッジ１２１の近傍から吸入ダクト部５０１ａに吸入され、フィルタ５０２を通過し、排気ファン５０３から送り出されて、第１開口部材５０４及び第２開口部材５０５を経て、排気口５１５をから吹き出される。 By driving the exhaust fan 503 of the mist recovery device 500, the air in the device main body 100 is sucked from the suction port 511 of the exhaust duct 501, and an air flow 600 is generated. The air flow 600 is sucked into the suction duct portion 501a from the vicinity of the carriage 121, passes through the filter 502, is sent out from the exhaust fan 503, passes through the first opening member 504 and the second opening member 505, and passes through the exhaust port 515. It is blown out.

次に、第１実施形態における第１開口部材及び第２開口部材について図５及び図６を参照して説明する。図５は同第１開口部材及び第２開口部材の説明に供する正面説明図であり、（ａ）は第１開口部材の正面説明図、（ｂ）は第２開口部材、（ｃ）は第１開口部材と第２開口部材とが重なる方向から見た説明図である。図６は排気ファンから排気口までの部分の平断面説明図である。 Next, the first opening member and the second opening member in the first embodiment will be described with reference to FIGS. 5 and 6. 5A and 5B are front explanatory views for explaining the first opening member and the second opening member, FIG. 5A is a front explanatory view of the first opening member, FIG. 5B is a second opening member, and FIG. 5C is a first. It is explanatory drawing which saw from the direction which 1 opening member and 2nd opening member overlap. FIG. 6 is a plan sectional explanatory view of a portion from the exhaust fan to the exhaust port.

第１開口部材５０４は、気流６００が通過するスリット形状の複数の第１開口部５０４ａと、気流６００の通過を阻止する第１開口部５０４ａ以外の壁部５０４ｂとを有している。 The first opening member 504 has a plurality of slit-shaped first openings 504a through which the airflow 600 passes, and wall portions 504b other than the first opening 504a that blocks the passage of the airflow 600.

第２開口部材５０５は、気流６００が通過するスリット形状の複数の第２開口部５０５ａと、気流６００の通過を阻止する第２開口部５０５ａ以外の壁部５０５ｂとを有している。 The second opening member 505 has a plurality of slit-shaped second openings 505a through which the airflow 600 passes, and a wall portion 505b other than the second opening 505a that blocks the passage of the airflow 600.

本実施形態では、第１開口部材５０４の複数の第１開口部５０４ａ及び複数の第２開口部材５０５の第２開口部５０５ａは、それぞれＸ方向に配列している。 In the present embodiment, the plurality of first openings 504a of the first opening member 504 and the second openings 505a of the plurality of second opening members 505 are arranged in the X direction, respectively.

そして、図５（ｃ）及び図６に示すように、隣り合う２つの開口部材となる第１開口部材５０４と第２開口部材５０５の内、上流側の開口部材となる第１開口部材５０４の第１開口部５０４ａは、下流側の開口部材となる第２開口部材５０５の壁部５０５ｂに対向して配置されている。 Then, as shown in FIGS. 5 (c) and 6, of the first opening member 504 and the second opening member 505 which are two adjacent opening members, the first opening member 504 which is the opening member on the upstream side The first opening 504a is arranged so as to face the wall portion 505b of the second opening member 505 which is the opening member on the downstream side.

本実施形態では、上流側の第１開口部材５０４のすべての第１開口部５０４ａが、下流側の第２開口部材５０５の壁部５０５ｂと全部が対向している構成としているが、これに限るものではない。 In the present embodiment, all the first openings 504a of the first opening member 504 on the upstream side face the wall portion 505b of the second opening member 505 on the downstream side, but the configuration is limited to this. It's not a thing.

このように構成したので、図６に示すように、排気ファン５０３から吹き出される気流６００は、第１開口部材５０４の第１開口部５０４ａに直接流入し、あるいは、壁部５０４ｂで方向を曲げられて、第１開口部５０４ａを通過する。 With this configuration, as shown in FIG. 6, the airflow 600 blown out from the exhaust fan 503 directly flows into the first opening 504a of the first opening member 504, or bends in the direction at the wall portion 504b. And pass through the first opening 504a.

この第１開口部材５０４の第１開口部５０４ａを通過した気流６００は、本実施形態では、第２開口部材５０５の壁部５０５ｂに衝突することで方向を曲げられて、第２開口部材５０５の第２開口部５０５ａを通過して、排気口５１５から外部に排出される。 In the present embodiment, the airflow 600 that has passed through the first opening 504a of the first opening member 504 is bent in the direction by colliding with the wall portion 505b of the second opening member 505, and the second opening member 505 It passes through the second opening 505a and is discharged to the outside from the exhaust port 515.

ここで、排気ファン５０３から吹き出される気流６００には、フィルタ５０２によって回収されなかったミストが含まれている。 Here, the airflow 600 blown out from the exhaust fan 503 contains mist that was not recovered by the filter 502.

このとき、気流６００が蛇行しながら第１開口部材５０４の第１開口部５０４ａ、第２開口部材５０５の第２開口部５０５ａを通過することで、気流６００の流速が低下している。したがって、気流６００に含まれるミストは、排気ダクト５０１の壁面、第１開口部材５０４の壁部５０４ｂ、第２開口部材５０５の壁部５０５ｂなどに付着し易くなる。 At this time, the airflow 600 passes through the first opening 504a of the first opening member 504 and the second opening 505a of the second opening member 505 while meandering, so that the flow velocity of the airflow 600 is reduced. Therefore, the mist contained in the air flow 600 tends to adhere to the wall surface of the exhaust duct 501, the wall portion 504b of the first opening member 504, the wall portion 505b of the second opening member 505, and the like.

これにより、排気口５１５から排出されるミストが低減する。 As a result, the amount of mist discharged from the exhaust port 515 is reduced.

なお、本実施形態のように第１開口部５０４ａ、及び、第２開口部５０５ａをスリット形状の開口部とすることで、形状を簡略化できる。 By using the first opening 504a and the second opening 505a as slit-shaped openings as in the present embodiment, the shape can be simplified.

次に、本発明の第２実施形態について図７を参照して説明する。図７は同実施形態における排気ファンから排気口までの部分の平断面説明図である。 Next, the second embodiment of the present invention will be described with reference to FIG. 7. FIG. 7 is a plan sectional explanatory view of a portion from the exhaust fan to the exhaust port in the same embodiment.

本実施形態では、前記第１実施形態と同様に、排気ファン５０３は、第１開口部材５０４及び第２開口部材５０５に対して偏って配置している。 In the present embodiment, as in the first embodiment, the exhaust fan 503 is arranged unevenly with respect to the first opening member 504 and the second opening member 505.

そして、第１開口部材５０４には、幅Ｗ１の第１開口部５０４ａを設けている。一方、第２開口部材５０５には、排気ファン５０３から離れるに従って幅Ｗ１～Ｗ３と広くなる３種類の第２開口部５０５ａ１、５０５ａ２，５０５ａ３を設けている。 The first opening member 504 is provided with a first opening 504a having a width W1. On the other hand, the second opening member 505 is provided with three types of second openings 505a1, 505a2, 505a3 having widths W1 to W3 as the distance from the exhaust fan 503 increases.

つまり、第２開口部材５０５には、排気ファン５０３から相対的に遠い側には、排気ファン５０３に近い側の第２開口部５０５ａ１よりも開口面積の大きい第２開口部５０５ａ２、５０５ａ３を設けている。また、この第２開口部５０５ａ２，５０５ａ３の開口面積は、第１開口部材５０４の第１開口部５０４ａよりも大きくしている。 That is, the second opening member 505 is provided with the second openings 505a2 and 505a3 having a larger opening area than the second opening 505a1 on the side closer to the exhaust fan 503 on the side relatively far from the exhaust fan 503. There is. Further, the opening area of the second opening 505a2, 505a3 is larger than that of the first opening 504a of the first opening member 504.

また、本実施形態では、上流側の第１開口部材５０４の一部の第１開口部５０４ａが、下流側の第２開口部材５０５の壁部５０５ｂと全部が対向し、残部の第１開口部５０４ａは第２開口部材５０５の第２開口部５０５ａ２，５０５ａ３に対向する構成としている。 Further, in the present embodiment, a part of the first opening 504a of the first opening member 504 on the upstream side faces the wall portion 505b of the second opening member 505 on the downstream side, and the remaining first opening portion The 504a is configured to face the second openings 505a2 and 505a3 of the second opening member 505.

このように、排気ファン５０３を第２開口部材５０５に対して偏って配置することで、第２開口部材５０５の排気ファン５０３から遠い部分の第２開口部５０５ａ２、５０５ａ３の開口面積を大きくしても、気流６００は第２開口部材５０５により蛇行されて排気口５１５から排気される。 By arranging the exhaust fan 503 in a biased manner with respect to the second opening member 505 in this way, the opening areas of the second openings 505a2 and 505a3 in the portion of the second opening member 505 far from the exhaust fan 503 are increased. However, the airflow 600 is meandered by the second opening member 505 and is exhausted from the exhaust port 515.

また、第２開口部材５０５の排気ファン５０３から遠い部分の第２開口部５０５ａ２．５０５ａ３の開口面積を近い部分の第２開口部５０５ａ１の開口面積より大きくすることで、気流６００は第２開口部５０５ａ２、５０５ａ３側では流れやすくなる。 Further, by making the opening area of the second opening 505a2.505a3 in the portion far from the exhaust fan 503 of the second opening member 505 larger than the opening area of the second opening 505a1 in the near portion, the airflow 600 is the second opening. It becomes easier to flow on the 505a2 and 505a3 sides.

したがって、通常は、排気ファン５０３から近い箇所の方が排気量は多いが、第２開口部の開口面積（大きさ）を変えることで、排気口５１５全体に分散されて排気されるようになる。 Therefore, normally, the displacement is larger in the portion closer to the exhaust fan 503, but by changing the opening area (size) of the second opening, the exhaust port 515 is dispersed and exhausted. ..

これにより、排気されるミストを含んだ気流６００は、より広い範囲に、より流速が遅い状態で排出されるので、ミストの装置外への付着を低減させることができる。 As a result, the airflow 600 including the exhausted mist is discharged over a wider range in a state where the flow velocity is slower, so that the adhesion of the mist to the outside of the device can be reduced.

次に、本発明の第３実施形態について図８及び図９を参照して説明する。図８は同実施形態における第１開口部材及び第２開口部材の説明に供する正面説明図であり、（ａ）は第１開口部材の正面説明図、（ｂ）は第２開口部材、（ｃ）は第１開口部材と第２開口部材とが重なる方向から見た説明図である。図９は排気ファンから排気口までの部分の平断面説明図である。 Next, the third embodiment of the present invention will be described with reference to FIGS. 8 and 9. 8A and 8B are front explanatory views for explaining the first opening member and the second opening member in the same embodiment, FIG. 8A is a frontal explanatory view of the first opening member, and FIG. 8B is a second opening member, (c). ) Is an explanatory view seen from the direction in which the first opening member and the second opening member overlap. FIG. 9 is a plan sectional explanatory view of a portion from the exhaust fan to the exhaust port.

本実施形態では、排気ファン５０３のＸ方向における幅と第１開口部材５０４及び第２開口部材５０５の幅はほぼ同じにしている。 In the present embodiment, the width of the exhaust fan 503 in the X direction and the width of the first opening member 504 and the second opening member 505 are substantially the same.

そして、第１開口部材５０４は、マトリクス状に配置された複数の第１開口部５０４ａを有し、第１開口部５０４ａ以外の部分は壁部５０４ｂとしている。同様に、第２開口部材５０５は、マトリクス状に配置された複数の第２開口部５０５ａを有し、第２開口部５０５ａ以外の部分は壁部５０５ｂとしている。 The first opening member 504 has a plurality of first openings 504a arranged in a matrix, and the portion other than the first opening 504a is a wall portion 504b.

Then, it is discharged from the exhaust port 515.

このとき、第１開口部材５０４の第１開口部５０４ａをマトリクス状に配置して第２開口部材５０５の壁部５０５ｂと対向させているので、矢印Ｘ方向だけでなく、矢印Ｚ方向でも気流６００の流れが乱れて、気流６００は第１実施形態よりも複雑な流れを生じることになる。 At this time, since the first opening 504a of the first opening member 504 is arranged in a matrix and faces the wall portion 505b of the second opening member 505, the airflow 600 is not only in the direction of arrow X but also in the direction of arrow Z.
