Hereinafter, the container cleaning apparatus of the present invention will be described with reference to the drawings.

図７は、本発明に従う容器洗浄装置の構成の一例を示す側面図である。
図７において、洗浄用液体供給手段は、洗浄用液体噴射ノズル１０に接続する洗浄用液体供給管７０と洗浄用液体供給ポンプ７１とからなる。回転手段は、回転モータ７２、回転モータに接続する駆動フリクションローラ７３、及び回転モータを上下方向に移動させるモータ移動用シリンダ７４からなる。ノズル移動手段は、洗浄用液体供給管に固定されたノズル移動用シリンダ７５、シリンダのレール７６からなる。 FIG. 7 is a side view showing an example of the configuration of the container cleaning device according to the present invention.
In FIG. 7, the cleaning liquid supply means includes a cleaning liquid supply pipe 70 and a cleaning liquid supply pump 71 connected to the cleaning liquid jet nozzle 10. The rotation means includes a rotation motor 72, a drive friction roller 73 connected to the rotation motor, and a motor moving cylinder 74 that moves the rotation motor in the vertical direction. The nozzle moving means includes a nozzle moving cylinder 75 and a cylinder rail 76 fixed to the cleaning liquid supply pipe.

上記容器洗浄装置による容器内壁面の洗浄は、例えば次のように行われる。
モータ移動用シリンダ７４により、駆動フリクションローラ７３が容器１に接するように回転モータ７２を下方向に移動させる。次いで、ノズル移動用シリンダ７５により、洗浄用液体噴射ノズル１０を容器１の内部に挿入し、洗浄用液体供給ポンプ７１により供給された洗浄用液体をノズルから噴射させ、回転モータ７２により駆動フリクションローラ７３を回転させながら、ノズル移動用シリンダ７５にてノズルを前後に移動させる。 The cleaning of the inner wall surface of the container by the container cleaning device is performed as follows, for example.
The rotation motor 72 is moved downward by the motor moving cylinder 74 so that the drive friction roller 73 is in contact with the container 1. Next, the cleaning liquid ejecting nozzle 10 is inserted into the container 1 by the nozzle moving cylinder 75, the cleaning liquid supplied by the cleaning liquid supply pump 71 is ejected from the nozzle, and the driving friction roller is driven by the rotation motor 72. While rotating 73, the nozzle is moved back and forth by the nozzle moving cylinder 75.

すすぎブース２４において用いるすすぎ用液体噴射ノズル２６は、前記の洗浄用液体噴射ノズルと同様に、軸方向に対して前方斜め方向にすすぎ用液体を噴射する前方斜方向噴射口及び軸方向に対して後方斜め方向にすすぎ用液体を噴射する後方斜方向噴射口をそれぞれ複数個にて備えていることが好ましい。容器内部へのすすぎ用液体の噴射には、上記のすすぎ用液体噴射ノズル、ノズルに洗浄用液体を供給する洗浄用液体供給手段、ノズル軸を中心に洗浄対象の容器を回転させる回転手段、及びノズルを軸方向にノズルを前後に移動させるノズル移動手段を有するすすぎ装置を用いることができる。   The rinsing liquid injection nozzle 26 used in the rinsing booth 24 is similar to the above-described cleaning liquid injection nozzle with respect to the front oblique direction injection port and the axial direction for injecting the rinsing liquid in the forward oblique direction with respect to the axial direction. It is preferable that a plurality of rear oblique injection ports for ejecting the rinsing liquid in the oblique rear direction are provided. For rinsing the rinsing liquid into the container, the rinsing liquid ejecting nozzle, a cleaning liquid supplying means for supplying the cleaning liquid to the nozzle, a rotating means for rotating the container to be cleaned around the nozzle axis, and A rinsing device having nozzle moving means for moving the nozzle back and forth in the axial direction can be used.

液体除去第一ブース２７において用いる液体除去用気体噴射ノズル２８及び液体除去第二ブース２９において用いる液体除去用気体噴射ノズル３０は、前記の洗浄用液体噴射ノズルと同様に、軸方向に対して前方斜め方向に液体除去用気体を噴射する前方斜方向噴射口及び軸方向に対して後方斜め方向に液体除去用気体を噴射する後方斜方向噴射口をそれぞれ複数個にて備えていることが好ましい。容器内部への液体除去用気体の噴射には、上記の液体除去用気体噴射ノズル、ノズルに液体除去用気体を供給する液体除去用気体供給手段、ノズル軸を中心に洗浄対象の容器を回転させる回転手段、及びノズルを軸方向にノズルを前後に移動させる移動手段を有する液体除去装置を用いることができる。   The liquid removal gas injection nozzle 28 used in the liquid removal first booth 27 and the liquid removal gas injection nozzle 30 used in the liquid removal second booth 29 are located in front of the axial direction in the same manner as the cleaning liquid injection nozzle. It is preferable that a plurality of front oblique injection ports for injecting the liquid removal gas in an oblique direction and a plurality of backward oblique injection ports for injecting the liquid removal gas in an oblique rearward direction with respect to the axial direction. Injecting the liquid removal gas into the container, the liquid removal gas injection nozzle, the liquid removal gas supply means for supplying the liquid removal gas to the nozzle, and the container to be cleaned around the nozzle axis are rotated. A liquid removing apparatus having a rotating means and a moving means for moving the nozzle back and forth in the axial direction can be used.

これまで円筒状容器を例にとり、本発明の洗浄方法について説明したが、矩形状の筒状容器を洗浄する場合は、容器を固定して、ノズルをノズル軸方向を中心として回転させる方が、装置の構成を簡易化できるので好ましい。また、管状体の場合はノズル軸方向への噴射が必要ない以外は、筒状容器の場合と同様に洗浄することができる。なお、配管などの長尺の管状体を洗浄する場合は、ノズルをノズル軸を中心として回転させることが好ましい。   So far, taking a cylindrical container as an example, the cleaning method of the present invention has been described, but when cleaning a rectangular cylindrical container, it is better to fix the container and rotate the nozzle around the nozzle axis direction, This is preferable because the configuration of the apparatus can be simplified. Further, in the case of a tubular body, it can be cleaned in the same manner as in the case of a cylindrical container, except that injection in the nozzle axis direction is not necessary. In addition, when cleaning long tubular bodies, such as piping, it is preferable to rotate a nozzle centering on a nozzle axis | shaft.
