In the final rinse washing step 30, the bottled drinking water sent from the supply pipe 46 is pressurized by the pump P3 and jetted from the jet port 31. The outer surface of the bottle B is washed.

上記のボトルＢの外面を洗浄する各洗浄工程における各洗浄水は、通常は各洗浄工程においてボトルＢ内部をそれぞれ洗浄する洗浄水と同一のものが使用される。従って、貯留槽４２，４３からポンプＰ１，Ｐ２に接続されている洗浄水Ｄ，Ｅの供給管４４，４５は、ボトルＢの内部洗浄用の各洗浄ノズル１２ａ，１２ｂ，１２ｃ及び２２ａにも接続され、また飲料水Ｆの供給管４６はポンプＰ３と供給管４６’を介してすすぎ洗浄工程３０の洗浄ノズル３２ａ，３２ｂに接続されている。 As the cleaning water in each cleaning process for cleaning the outer surface of the bottle B, the same cleaning water as that for cleaning the inside of the bottle B in each cleaning process is usually used. Accordingly, the supply pipes 44 and 45 of the cleaning water D and E connected from the storage tanks 42 and 43 to the pumps P1 and P2 are also connected to the cleaning nozzles 12a, 12b, 12c and 22a for cleaning the inside of the bottle B. The drinking water F supply pipe 46 is connected to the washing nozzles 32a and 32b of the rinsing washing step 30 via the pump P3 and the supply pipe 46 '.

これらの天井部付近に設けられた噴射口１１，２１，３１からの洗浄水Ｄ，Ｅ，Ｆの噴射が水霧状に噴霧されることで、ボトルＢの外周面を洗浄するとともに洗浄・殺菌工程１０などの温水使用に伴って洗浄槽２内に発生する湯気を急速に水滴化し消失させることができ、湯気発生に伴う問題を解消し、ダクトなどの排気装置の設置を不要とすることができる。 By spraying the sprays of cleaning water D, E, and F from the spray ports 11, 21, and 31 provided in the vicinity of these ceilings in the form of water mist, the outer peripheral surface of the bottle B is cleaned and cleaned and sterilized. Steam generated in the washing tank 2 due to the use of hot water in the step 10 can be quickly dropped into water, and the problem associated with the generation of steam can be eliminated, making it unnecessary to install an exhaust device such as a duct. it can.

本実施形態では、洗浄と殺菌とが同一の洗浄・殺菌工程１０において実施され、洗浄水として次亜塩素酸ソーダや苛性ソーダなどの殺菌剤を含む５０〜６０℃の殺菌洗浄水Ｄが用いられている。洗浄と殺菌とを別工程で行う場合は、洗浄工程では通常５０〜６０℃の温水が、殺菌工程では次亜塩素酸ソーダなどのを含む５０〜６０℃の殺菌水が使用される。 In this embodiment, cleaning and sterilization are performed in the same cleaning / sterilization step 10, and sterilized cleaning water D of 50 to 60 ° C. containing a sterilizing agent such as sodium hypochlorite and caustic soda is used as the cleaning water. Yes. When washing and sterilization are performed in separate steps, hot water of 50 to 60 ° C. is usually used in the cleaning step, and sterilized water of 50 to 60 ° C. containing sodium hypochlorite is used in the sterilization step.

この洗浄・殺菌工程１０の先頭位置においては、回転ブラシ１３，１４によって空ボトルＢの外側面と外底面がブラシ洗浄され、ボトルＢの外周面に付着した付着物や汚れを除去し外観性を向上するものとなる。 At the head position of this cleaning / sterilization step 10, the outer surface and the outer bottom surface of the empty bottle B are brush-washed by the rotating brushes 13 and 14, and the appearance and appearance are removed by removing the deposits and dirt adhering to the outer peripheral surface of the bottle B. It will be improved.

この洗浄・殺菌工程１０では、循環コンベヤＣの間欠運転により所定の３箇所の洗浄位置に空ボトルＢが停止した際に、貯留槽４２に溜められた殺菌洗浄水ＤがポンプＰ１によって吸引、加圧され供給管４４を経由して洗浄ノズル１２ａ，１２ｂ，１２ｃ（２ラインで合計６個）に送られ、それに連結された各洗浄ノズル１２ａ，１２ｂ，１２ｃが昇降シリンダー（図示せず）により各ボトルＢの口部近傍に挿入され、前記殺菌洗浄水Ｄがノズル口から拡散されながらボトルＢ内に噴射され洗浄と殺菌を行うと同時に、上部の噴射口１１から殺菌洗浄水Ｄを噴霧してボトルＢの外面を洗浄するとともに水霧状の噴霧により洗浄槽２内の湯気を急速に冷却し消失することができる。 In this cleaning / sterilization process 10, when the empty bottle B is stopped at three predetermined cleaning positions by intermittent operation of the circulation conveyor C, the sterilized cleaning water D stored in the storage tank 42 is sucked and added by the pump P1. The pressure is compressed and sent to the cleaning nozzles 12a, 12b, and 12c (total of six in two lines) via the supply pipe 44, and the cleaning nozzles 12a, 12b, and 12c connected to the nozzles are respectively moved by lift cylinders (not shown). Inserted in the vicinity of the mouth of the bottle B, the sterilizing washing water D is sprayed into the bottle B while being diffused from the nozzle opening, and at the same time, the sterilizing washing water D is sprayed from the upper injection port 11. The outer surface of the bottle B can be cleaned and the steam in the cleaning tank 2 can be rapidly cooled and disappeared by spraying water mist.

本実施形態においては、洗浄・殺菌工程１０の後にボトル内に残る殺菌洗浄水ＤをボトルＢ外に排出する排水工程５０を設けている。このように前工程での洗浄殺菌水ＤをボトルＢ内から排除することで、次のすすぎ工程２０でのすすぎ洗浄力を向上することができる。この排水工程５０は、洗浄作業を行わない工程を前後の洗浄工程間に設けることで、倒立状態にあるボトルＢの口部から残留水を自然落下させることにより容易に実施できる。また、場合によってはこの排水工程５０を省略してもよい。 In the present embodiment, a drainage process 50 for discharging the sterilized cleaning water D remaining in the bottle after the cleaning / sterilization process 10 to the outside of the bottle B is provided. Thus, by removing the cleaning sterilizing water D in the previous step from the bottle B, the rinsing cleaning power in the next rinsing step 20 can be improved. The draining process 50 can be easily performed by naturally dropping the residual water from the mouth of the bottle B in an inverted state by providing a process that does not perform the cleaning operation between the previous and subsequent cleaning processes. In some cases, this draining step 50 may be omitted.

次のすすぎ洗浄工程２０では、洗浄水としてオゾンを０．２〜１ｐｐｍ、好ましくは０．４〜０．６ｐｐｍ程度含有する５０〜６０℃のオゾン水ＥがボトルＢ内に噴射されすすぎ洗浄が行われ、前の洗浄・殺菌工程１０において残留する洗浄殺菌水Ｄを洗い流すとともに、内部に残った殺菌剤の臭いを脱臭することができる。このオゾン水処理はボトル詰め飲料水の異臭発生の問題を大幅に改善するものとなり、また殺菌効果も向上する。 In the next rinsing step 20, ozone water E containing ozone of 0.2 to 1 ppm, preferably about 0.4 to 0.6 ppm as washing water is injected into the bottle B to perform rinsing washing. In addition, it is possible to wash away the cleaning sterilizing water D remaining in the previous cleaning / sterilization step 10 and deodorize the odor of the germicide remaining inside. This ozone water treatment greatly improves the problem of odor generation in bottled drinking water, and also improves the bactericidal effect.

このオゾン水Ｅによるすすぎ洗浄工程２０においても、前工程と同様に、循環コンベヤＣの間欠運転により所定のすすぎ位置に空ボトルＢが停止した際に、貯留槽４３に溜められたオゾン水ＥがポンプＰ２によって吸引、加圧され供給管４５を経由して洗浄ノズル２２ａ（合計２個）に送られ、洗浄ノズル２２ａが昇降シリンダー（図示せず）により各ボトルＢの口部近傍に挿入され、ノズル口からオゾン水ＥをボトルＢ内に拡散させながら噴射することによりすすぎ洗浄を行うと同時に、上部の噴射口２１からオゾン水Ｅが水霧状に噴霧されボトルＢの外面の洗浄、脱臭を行い、同時に周辺の湯気を消失させる。 Also in the rinsing cleaning process 20 using the ozone water E, when the empty bottle B is stopped at a predetermined rinsing position due to the intermittent operation of the circulation conveyor C, the ozone water E stored in the storage tank 43 is removed as in the previous process. It is sucked and pressurized by the pump P2 and sent to the cleaning nozzles 22a (two in total) via the supply pipe 45, and the cleaning nozzles 22a are inserted in the vicinity of the mouth of each bottle B by the lifting cylinder (not shown), Rinsing and cleaning are performed by spraying ozone water E from the nozzle port while diffusing into the bottle B. At the same time, ozone water E is sprayed in a water mist form from the upper spray port 21 to clean and deodorize the outer surface of the bottle B. At the same time to eliminate the surrounding steam.

これらの殺菌・洗浄工程１０及びすすぎ洗浄工程２０では、同一洗浄工程内の複数の洗浄ノズル１２ａ，１２ｂ，１２ｃ及び２２ａはそれぞれ１つのノズル昇降シリンダー装置（図示せず）に連結され、ボトルＢの口部近傍に挿入されるようになっている。 In these sterilization / washing process 10 and rinsing washing process 20, a plurality of washing nozzles 12a, 12b, 12c and 22a in the same washing process are connected to one nozzle lifting cylinder device (not shown), respectively. It is inserted near the mouth.

最終のすすぎ洗浄工程３０では、供給管４６から送られてきた新鮮な飲料水ＦがポンプＰ３を介して加圧され洗浄ノズル３２ａ，３２ｂによってボトルＢ内部の仕上げのすすぎ洗浄が行われ、また供給管４６’からの飲料水Ｆは噴射口３１にも送られボトルＢの外面を洗浄し前工程のオゾン水Ｅなどの混入を防止し、ボトル洗浄の仕上げが行われる。 In the final rinsing process 30, fresh drinking water F sent from the supply pipe 46 is pressurized through the pump P3, and the rinsing cleaning of the inside of the bottle B is performed by the cleaning nozzles 32a and 32b. Drinking water F from the pipe 46 ′ is also sent to the injection port 31 to clean the outer surface of the bottle B to prevent mixing of ozone water E and the like in the previous process, and finish the bottle cleaning.

この最終のすすぎ工程３０では、通常、常温の水が使用され、ボトル本体の温度上昇を抑え充填される飲料水等の変質を防ぐようにしている。しかし、充填物によっては温水の使用も可能であり、充填内容により使用水の温度を選択することができる。 In this final rinsing step 30, water at normal temperature is usually used so as to prevent the quality of the bottled water and the like from being altered by suppressing the temperature rise of the bottle body. However, depending on the filling, warm water can be used, and the temperature of the used water can be selected according to the filling content.

この最終のすすぎ工程３０では、循環コンベヤＣの間欠運転により所定の２箇所のすすぎ位置に空ボトルＢが停止した際に、連結された洗浄ノズル３２ａ，３２ｂ（合計４個）が昇降シリンダーにより各ボトルＢの口部からボトルＢ内部に挿入され、同時にポンプＰ３が作動し加圧された飲料水Ｆが供給管４６’を経て洗浄ノズル３２ａ，３２ｂに圧送される。 In this final rinsing step 30, when the empty bottle B is stopped at two predetermined rinsing positions by intermittent operation of the circulation conveyor C, the connected cleaning nozzles 32a and 32b (four in total) are moved by the lifting cylinders. The drinking water F, which is inserted into the inside of the bottle B from the mouth of the bottle B and is simultaneously operated and pressurized, is pumped to the washing nozzles 32a and 32b through the supply pipe 46 '.

この最終のすすぎ工程３０で使用される洗浄ノズル３２は、図３に示すように、倒立支持された空ボトルＢの口部５１からボトルＢの内部に略垂直に挿入されるもので、ボトル内面に向けて飲料水Ｆを洗浄水として噴射口から円錐形状に拡げて噴射する４個の噴射口３３，３４，３５，３６をボトル内面５２の側面に対して９０度毎の等角度間隔でノズル軸方向の上下に設け、また洗浄ノズル３２の頭部にはボトル内面５２の天井面に向けて飲料水を噴射口から円錐形状に拡げて噴射する噴射口３７を設けている。 As shown in FIG. 3, the cleaning nozzle 32 used in the final rinsing step 30 is inserted into the bottle B from the mouth portion 51 of the empty bottle B that is inverted and supported substantially vertically. The four injection ports 33, 34, 35, and 36 that spray the drinking water F into the conical shape from the injection port as the cleaning water toward the nozzle are spaced at equal angular intervals of 90 degrees with respect to the side surface of the bottle inner surface 52. An injection port 37 is provided at the top and bottom in the axial direction, and at the head of the washing nozzle 32, the drinking water 37 is sprayed from the injection port in a conical shape toward the ceiling surface of the bottle inner surface 52.

この洗浄ノズル３２は、昇降シリンダーによってボトルＢの内部を上下動することができ、ボトルＢ全体の内面形状や内周壁の凹凸形状に合わせて動作させることで、図４に示すように、洗浄ノズル３２の各噴射口３３，３４，３５，３６及び３７から拡がって噴射される飲料水ＦがボトルＢ内部の隅々まで行き渡り、特に洗浄ノズル３２の頭部に噴射口３７を設けることで、天井面を洩れなく洗浄するとともにボトル内面５２に当たった水の下方への流れ良くし洗浄効果を向上することができる。 The cleaning nozzle 32 can be moved up and down inside the bottle B by an elevating cylinder, and is operated in accordance with the inner surface shape of the entire bottle B and the uneven shape of the inner peripheral wall. As shown in FIG. The drinking water F that is spread and sprayed from each of the 32 spray ports 33, 34, 35, 36, and 37 spreads to every corner of the bottle B, and in particular, by providing the spray ports 37 at the head of the cleaning nozzle 32, the ceiling It is possible to clean the surface without omission and improve the flow of water that hits the bottle inner surface 52 downward, thereby improving the cleaning effect.

しかも、洗浄ノズル３２がボトルＢ内部を上下動することで、ボトルＢ内面の細かい凹凸部を見逃すことなく洗い流し、水の流れない死角を無くして完全にすすぎ洗浄を行うことができる。また、このノズル３２の上下動はボトルＢ内の洗浄後排水の排出効果を向上することもできる。 In addition, since the cleaning nozzle 32 moves up and down in the bottle B, it is possible to wash away without overlooking the fine irregularities on the inner surface of the bottle B, and it is possible to completely rinse with no blind spots where water does not flow. Further, the vertical movement of the nozzle 32 can also improve the discharge effect of the waste water after washing in the bottle B.

勿論、この複数の噴射口を有しボトルＢ内を上下動する洗浄ノズル３２は、前の洗浄・殺菌工程１０及びオゾン水Ｅによるすすぎ工程２０においても使用することができ、これによりボトルＢ内の洗浄効果をより向上することができる。 Of course, the cleaning nozzle 32 having a plurality of injection ports and moving up and down in the bottle B can also be used in the previous cleaning / sterilization step 10 and the rinsing step 20 with the ozone water E. The cleaning effect can be further improved.

図５及び図６は、前記洗浄ノズル３２のボトルＢ内部での上下動を示すもので、供給管４６からポンプ３を介した飲料水Ｆの供給管４６’が接続された連結具６２に先端部に洗浄ノズル３２ａ，３２ｂを備えたノズル支持管６３が連結され、それぞれの連結具６２，６２の中央部にシリンダー装置６１ａ，６１ｂが上方から接続されている。このシリンダー装置６１ａ，６１ｂの昇降により洗浄ノズル３２ａ、３２ｂはボトルＢ内を上下動し（図５の（ａ）はノズル３２ａの下降時、（ｂ）はノズル３２ｂの上昇時を示す）、その動きを制御することでボトルＢ内の隅々まで洗浄することができる。 5 and 6 show the vertical movement of the washing nozzle 32 inside the bottle B, and the tip of the supply pipe 46 is connected to a connecting tool 62 to which a supply pipe 46 ′ of drinking water F is connected via the pump 3. The nozzle support pipe 63 provided with the washing nozzles 32a and 32b is connected to the part, and the cylinder devices 61a and 61b are connected from above to the central parts of the respective connecting tools 62 and 62. As the cylinder devices 61a and 61b move up and down, the cleaning nozzles 32a and 32b move up and down in the bottle B ((a) in FIG. 5 shows when the nozzle 32a is lowered, and (b) shows when the nozzle 32b is raised). By controlling the movement, every corner of the bottle B can be washed.

さらに、本発明では、前記洗浄槽２の後方外部に連続して、洗浄されたボトルＢに飲料水Ｆの充填工程７０を設けることもできる。このように飲料水Ｆの充填工程７０を連結させることで、ボトル詰め飲料水の製造効率を大幅に向上させることができる。 Furthermore, in the present invention, a drinking water F filling step 70 can be provided on the washed bottle B continuously outside the washing tank 2. Thus, by connecting the filling process 70 of the drinking water F, the manufacturing efficiency of bottled drinking water can be improved significantly.
