本発明によれば、次の効果を得ることができる。
（１）請求項１の発明によれば、筒状支柱部の上端から容器天面に沿う方向に筒状梁部を設け、筒状支柱部の上端から側部に連続する噴射流を形成するように噴射孔を設けたので、開口部を下方にして載置した容器天面すなわち容器の内底面を含めて隅々まで的確に水切りすることができ、高度の清浄性を確保できる。
（２）しかも、ノズルを昇降かつ回転可能に構成したので、容器の内面全体に対して効率的に高度の清浄性を得ることができる。
（３）請求項２の発明によれば、筒状梁部の側面の噴射孔を上方から順次回転方向後方へずらして傾斜した位置に穿設したので、それらの各噴射孔からのエアによって傾斜したエア噴射流が形成されることから、前記筒状梁部を回転しながらエアを噴射することにより、容器側壁部の内面に付着した液滴を下方へ掻き落すように水切りすることができる。
（４）請求項３の発明によれば、前記筒状梁部の先端部近傍の噴射孔の開口量を大きく形成したので、容器の内底面の周辺部の液滴の除去しにくい隅部に強力なエア噴射流が吹付けられることから、より的確な水切り処理が可能である。

(1) According to the first aspect of the present invention, the cylindrical beam portion is provided in the direction along the top of the container from the upper end of the cylindrical support column, and a jet flow continuous from the upper end of the cylindrical support column to the side is formed. Since the injection hole is provided as described above, it is possible to accurately drain water to every corner including the top surface of the container placed with the opening portion downward, that is, the inner bottom surface of the container, and a high degree of cleanliness can be secured.
(2) Moreover, since the nozzle is configured to be movable up and down and rotated, a high degree of cleanliness can be obtained efficiently over the entire inner surface of the container.
(3) According to the invention of claim 2, since the injection holes on the side surface of the cylindrical beam portion are formed in the inclined positions by sequentially shifting from the upper side to the rear in the rotation direction, the injection holes are inclined by the air from the respective injection holes. Since the air jet flow thus formed is formed, by spraying air while rotating the cylindrical beam portion, it is possible to drain water so that the liquid droplets adhering to the inner surface of the container side wall portion are scraped downward.
(4) According to the invention of claim 3, since the opening amount of the injection hole in the vicinity of the tip end portion of the cylindrical beam portion is formed large, it is difficult to remove the droplet on the peripheral portion of the inner bottom surface of the container. Since a powerful air jet stream is sprayed, more accurate drainage treatment is possible.
(5) According to the invention of claim 4, after the nozzle is rotated by a predetermined angle at the rising end position and then lowered while rotating, the liquid is gradually lowered from the top surface to the side surface of the container inner surface and from the upper side of the side surface downward.

本発明は、薬剤原料用のステンレス容器などの高度の清浄性が要求される容器の洗浄装置に使用される洗浄後の水切り装置として好適であるが、それに限定されることなく、容器内面の水切り装置として広く適用することが可能である。本発明では、容器は開口部を下方にして載置された状態において水切り処理を受けることになる。その水切り処理は、容器の内面にノズルからのエアを吹付けて付着する洗浄液等の液体を除去するという手法が採られる。ノズルは、容器の中心にほぼ沿って配設される筒状支柱部と、該筒状支柱部の上端から容器天面に沿う方向に取付けられる筒状梁部とから構成される。この場合、容器天面の形状が単純な平坦面でない場合には、その形状に合わせて筒状梁部の上面を沿わせるように形成することも可能である。筒状梁部には、筒状支柱部の上端部から側部に連続する噴射流が形成されるように噴射孔が設けられる。この筒状梁部の上部に形成される噴射孔の向きは、回転方向斜め前方を向くように形成した方が望ましいが、真上に向くように形成したものでもよい。また、その噴射孔は、スリット状の細長い形状のものでも、一列に並べて形成された多数の孔でもよく、要は連続した噴射流が形成されるものであればよい。さらに、筒状梁部は筒状支柱部を中心に片方だけ設けたものでもよいし、３つ以上設けたものでもよい。そして、以上の筒状支柱部と筒状梁部から構成される前記ノズルは昇降かつ回転可能に構成されている。なお、水切り室への搬送時に容器の上面にエアを吹付けて水切り処理を行い、搬送停止時に容器の内面と外側面を水切り処理するように切替えるように構成すれば、効率的な処理が可能である。また、搬送停止時に容器を搬送手段からわずかに持上げるように構成すれば、容器の下端部からの水の切れがよくなる。前記筒状梁部の側面の噴射孔を、上方から順次回転方向後方へずらして傾斜した位置に穿設すれば、容器の側壁部内面に付着した液滴の除去に効果的である。前記筒状梁部の先端部近傍の噴射孔の開口量を大きく形成すれば、容器の内底面周辺部の隅部の水切りに有効である。前記ノズルを上昇端位置で所定角度回転した後、回転しながら下降させるように構成すれば、容器内面の天面から側面へ、側面上部から下方へ液滴を的確に移動させることができる。 The present invention is suitable as a draining device after washing used in a washing device for a container that requires a high degree of cleanliness, such as a stainless steel container for a pharmaceutical raw material, but is not limited thereto, and drains the inner surface of the container. It can be widely applied as a device. In the present invention, the container is subjected to a draining process in a state where the container is placed with the opening portion downward. The draining process employs a technique of removing the liquid such as the cleaning liquid that adheres by blowing air from the nozzle to the inner surface of the container. The nozzle is composed of a cylindrical column portion that is disposed substantially along the center of the container, and a cylindrical beam portion that is attached in a direction along the container top surface from the upper end of the cylindrical column portion. In this case, if the shape of the top surface of the container is not a simple flat surface, it can be formed so that the upper surface of the cylindrical beam portion is along the shape. The cylindrical beam portion is provided with an injection hole so as to form a continuous injection flow from the upper end portion of the cylindrical column portion to the side portion. The direction of the injection hole formed in the upper portion of the cylindrical beam portion is preferably formed so as to face obliquely forward in the rotational direction, but may be formed so as to face directly above. In addition, the injection hole may be a slit-like elongated shape, or may be a large number of holes formed in a line, and may be anything as long as a continuous injection flow is formed. Further, only one of the cylindrical beam portions may be provided around the cylindrical support column portion, or three or more cylindrical beam portions may be provided. And the said nozzle comprised from the above cylindrical support | pillar part and a cylindrical beam part is comprised so that raising / lowering and rotation are possible. Efficient processing is possible if it is configured to spray water on the upper surface of the container when transporting to the draining chamber, and to switch to draining the inner and outer surfaces of the container when transport is stopped It is. Further, if the container is configured to be slightly lifted from the conveying means when the conveyance is stopped, the water breaks off from the lower end of the container. If the injection holes on the side surface of the cylindrical beam part are formed at positions inclined by shifting backward from the upper side in the rotation direction, it is effective for removing the droplets adhering to the inner surface of the side wall part of the container. If the opening amount of the injection hole in the vicinity of the distal end portion of the cylindrical beam portion is formed large, it is effective for draining the corners around the inner bottom surface of the container. If the nozzle is rotated at a rising end position by a predetermined angle and then lowered while rotating, the droplet can be accurately moved from the top surface to the side surface of the container inner surface and from the upper portion of the side surface downward.

図１は本発明の実施例に係る水切り装置の内部を示した要部構成図である。図示のように、本実施例に係る水切り装置１では、洗浄処理等の前工程を経て容器２は開口部を下方にして載置された状態で水切り室３内に搬入される。容器２の停止位置の上方には、容器２の外側面にエアを吹付けて表面に付着した洗浄水等の液滴を除去するノズル４〜７が昇降可能に設置されている。このノズル４〜７は、図２に示したように容器２の周囲を取囲むように配設されており、その中のノズル６，７は容器２の取っ手と干渉しないように外側に変位して設けられている。各ノズル４〜７は、図３の縦断面図に示したように内部にエア室８が形成され、下方の隅部にスリット状の噴射孔９が形成されている。しかして、容器２が水切り室３へ搬送されて所定の停止位置に停止すると、ノズル４〜７の各エア室８内に図示しないターボファン等の送風機からエアが送られ、スリット状の噴射孔９から扁平状のエア噴射流が容器２の外側面へ向けて吹出される。同時に各ノズル４〜７の下降を始めると、容器２の外側面に付着した液滴は流下して下方へ除去される。この場合に、容器２を搬送手段の載置面から少し持上げて離間するように構成すれば水の切れがよく、より効果的な水切りが可能である。因みに、容器２の上面に付着した液滴の水切りに関しては、水切り室３の入口に配設した、図示しない容器２の上面の直径より長い長さを有する筒状ノズルの下部に形成されたスリット状の噴射孔から噴射されるエアの中を通過する際に水切り処理される。 FIG. 1 is a main part configuration diagram showing the inside of a drainer according to an embodiment of the present invention. As shown in the figure, in the draining device 1 according to the present embodiment, the container 2 is carried into the draining chamber 3 in a state where the container 2 is placed with the opening portion downward through a pre-process such as a cleaning process. Above the stop position of the container 2, nozzles 4 to 7 that blow air on the outer surface of the container 2 to remove liquid droplets such as cleaning water attached to the surface are installed so as to be movable up and down. The nozzles 4 to 7 are arranged so as to surround the periphery of the container 2 as shown in FIG. 2, and the nozzles 6 and 7 therein are displaced outward so as not to interfere with the handle of the container 2. Is provided. As shown in the longitudinal sectional view of FIG. 3, each of the nozzles 4 to 7 has an air chamber 8 formed therein, and a slit-like injection hole 9 formed in a lower corner. When the container 2 is transported to the draining chamber 3 and stopped at a predetermined stop position, air is sent from a blower such as a turbo fan (not shown) into each air chamber 8 of the nozzles 4 to 7 to form a slit-like injection hole. A flat air jet flow is blown from 9 toward the outer surface of the container 2. At the same time, when the nozzles 4 to 7 start to descend, the droplets adhering to the outer surface of the container 2 flow down and are removed downward. In this case, if the container 2 is configured to be slightly lifted away from the placement surface of the transport means, the water is well drained, and more effective draining is possible. Incidentally, regarding the draining of the droplets adhering to the upper surface of the container 2, a slit formed at the lower part of a cylindrical nozzle having a length longer than the diameter of the upper surface of the container 2 (not shown) disposed at the inlet of the draining chamber 3. A draining process is performed when the air passes through the air injected from the injection hole.

次に、本発明の特徴部分である容器２の内面の水切り処理に関して説明する。図１に示したように、容器２の停止位置の下方には内面水切り用のノズル１０が昇降及び回転可能に配設されている。このノズル１０は、容器２の中心にほぼ沿って配設される筒状支柱部１１と、その筒状支柱部１１の上端から容器天面に沿う方向に取付けられた筒状梁部１２とから構成される。筒状梁部１２には、筒状支柱部１１の上端部から側部に連続する噴射流が形成されるように噴射孔を設けられており、二点鎖線で示したように容器本体２の内部へ上昇させて、筒状梁部１２の前記噴射孔からエアを吹出しながら回転させて徐々に下降させることにより、容器本体２の内側の天面及び側面に付着した洗浄液等の液滴を効率的に水切りできるように構成している。 Next, the draining process of the inner surface of the container 2 which is a characteristic part of the present invention will be described. As shown in FIG. 1, a nozzle 10 for draining the inner surface is disposed below the stop position of the container 2 so as to be movable up and down. The nozzle 10 includes a cylindrical support 11 disposed substantially along the center of the container 2 and a cylindrical beam 12 attached in the direction from the upper end of the cylindrical support 11 to the top of the container. Composed. The cylindrical beam portion 12 is provided with an injection hole so as to form a continuous injection flow from the upper end portion of the cylindrical support column portion 11 to the side portion, and as shown by a two-dot chain line, The liquid droplets such as cleaning liquid adhering to the inner top surface and the side surface of the container main body 2 are efficiently removed by being lifted to the inside, rotated while being blown out from the injection holes of the cylindrical beam portion 12, and gradually lowered. It is configured so that it can be drained.

図４はノズル１０の回転昇降機構を示した部分拡大図である。図示のように、ノズル１０の筒状支柱部１１は、ベアリング１３を介してチェーン１４に固定された昇降基板１５に対して回転可能に支持されている。チェーン１４は、スプロケット１６と昇降用モータ１７の駆動輪１８との間に張設された歯付きベルト１９を介して昇降駆動されるように構成されている。また、昇降基板１５には回転用モータ２０が筒状支柱部１１と共に昇降し得るように支持され、その出力軸２１に固着されたギヤ２２に歯合したギヤ２３を介して筒状支柱部１１を回転可能に構成されている。しかして、ノズル１０は、昇降用モータ１７によりチェーン１４を昇降駆動することにより昇降基板１５に支持された筒状支柱部１１を介して昇降し得るとともに、回転用モータ２０によりギヤ２２，２３を介して回転させることができる。 FIG. 4 is a partially enlarged view showing the rotary lifting mechanism of the nozzle 10. As shown in the figure, the cylindrical column portion 11 of the nozzle 10 is supported so as to be rotatable with respect to the elevating board 15 fixed to the chain 14 via a bearing 13. The chain 14 is configured to be lifted and lowered via a toothed belt 19 stretched between the sprocket 16 and the drive wheel 18 of the lifting motor 17. Further, a rotating motor 20 is supported on the elevating board 15 so as to be able to move up and down together with the cylindrical support column 11, and the cylindrical support unit 11 is connected via a gear 23 engaged with a gear 22 fixed to the output shaft 21. It is configured to be rotatable. Thus, the nozzle 10 can be moved up and down through the cylindrical support column 11 supported by the lift board 15 by driving the chain 14 up and down by the lift motor 17, and the gears 22 and 23 can be moved by the rotation motor 20. Can be rotated through.

図５〜図８はノズル１０を示した拡大部品図であり、図５はその正面図、図６は平面図、図７は右側面図、図８は図６のＡ−Ａ断面図である。図示のように、ノズル１０を構成する筒状支柱部１１の下部には所要数の給気口２４が形成されており、図示しない前記送風機からエアが筒状支柱部１１内に供給されるように構成されている。図６に示したように、筒状支柱部１１の上端部には傾斜状に複数の小孔からなる噴射孔２５が形成されているとともに、その筒状支柱部１１の上端から容器天面に沿う方向に取付けられた筒状梁部１２には前記噴射孔２５を中心に両側に回転方向前方側に多数の小孔からなる噴射孔２６，２７が直線状に形成されている。なお、本実施例では、噴射孔２６，２７の最外部にスリット状の噴射孔２８，２９を形成し、筒状梁部１２の先端部近傍の噴射孔の開口量を大きくすることにより、容器２の天面すなわち内底面周辺部の隅部の水切りを促進するようにしている。しかして、これらの噴射孔２５〜２９から噴射されるエアによって、筒状支柱部１１の上端部から側部に連続する噴射流が形成されることになる。 5 to 8 are enlarged part views showing the nozzle 10, FIG. 5 is a front view thereof, FIG. 6 is a plan view, FIG. 7 is a right side view, and FIG. . As shown in the drawing, a required number of air supply ports 24 are formed in the lower portion of the cylindrical support 11 constituting the nozzle 10 so that air is supplied into the cylindrical support 11 from the blower (not shown). It is configured. As shown in FIG. 6, the upper end portion of the cylindrical support column 11 is formed with an injection hole 25 composed of a plurality of small holes in an inclined manner, and from the upper end of the cylindrical support column 11 to the top of the container. The cylindrical beam portion 12 attached in the direction along which the injection holes 26 and 27 are formed in a straight line on the both sides of the injection hole 25 on the front side in the rotational direction. In this embodiment, the slit-shaped injection holes 28 and 29 are formed in the outermost part of the injection holes 26 and 27, and the opening amount of the injection holes in the vicinity of the distal end portion of the cylindrical beam portion 12 is increased, whereby the container The drainage of the corners of the top surface of 2, ie, the inner bottom surface peripheral portion, is promoted. Accordingly, the air jetted from these jet holes 25 to 29 forms a jet flow that continues from the upper end portion of the cylindrical column portion 11 to the side portion.

さらに、筒状梁部１２の両端側面には、図７及び図８に示したように上方から順次回転方向後方へずらして傾斜した位置に、前記スリット状の噴射孔２８，２９に連なる所要数の小孔からなる噴射孔３０，３１を形成している。そして、これらの噴射孔２８〜３１からのエアにより傾斜したエア噴射流が形成されるので、筒状梁部１２を回転しながら下降すれば、容器２の側壁部の内面に付着した液滴は下方へ掻き落されるように効率的に水切りされる。なお、筒状梁部１２の１回転当りの降下量は、その両端面に形成されたスリット状の噴射孔２８，２９及び小孔の噴射孔３０，３１からの噴射流の上下幅からみて上下方向の吹付けもれがなく連続的に吹付けられるように設定される。すなわち、本実施例のように筒状梁部１２の両端面に噴射孔２８〜３１が形成され、両側で噴射流が形成される場合の１回転当りの降下量は、それらの噴射孔からの噴射流の上下幅の２倍以下に設定されることになる。 Further, on both side surfaces of the cylindrical beam portion 12, as shown in FIGS. 7 and 8, the required number connected to the slit-like injection holes 28 and 29 at positions inclined sequentially from the upper side to the rear in the rotational direction. The injection holes 30 and 31 are formed of small holes. And since the inclined air jet flow is formed by the air from these jet holes 28-31, if it falls while rotating the cylindrical beam part 12, the droplet adhering to the inner surface of the side wall part of the container 2 will be It is drained efficiently so that it is scraped downward. Note that the amount of descent per rotation of the cylindrical beam portion 12 increases and decreases as viewed from the vertical width of the injection flow from the slit-like injection holes 28 and 29 and the small-hole injection holes 30 and 31 formed on both end faces thereof. It is set so that there is no leakage of the direction and it is continuously sprayed. That is, when the injection holes 28 to 31 are formed on both end faces of the cylindrical beam portion 12 as in the present embodiment, and the injection flow is formed on both sides, the amount of descent per rotation is from these injection holes. It is set to be not more than twice the vertical width of the jet flow.

しかして、図１で二点差線で示したように、ノズル１０を容器２内の上昇端位置で所定角度回転した後、回転しながら下降させるようにすれば、容器２の内面に付着した液滴を天面から側面へ、さらに側面上部から下方へ徐々に移動させることができ、きわめて効率的かつ的確な水切り処理が可能である。 Thus, as shown by the two-dot chain line in FIG. 1, if the nozzle 10 is rotated by a predetermined angle at the rising end position in the container 2 and then lowered while rotating, the liquid adhered to the inner surface of the container 2. Drops can be gradually moved from the top surface to the side surface, and further from the upper side of the side surface to the lower side, enabling extremely efficient and accurate draining treatment.
