  On the other hand, the container table 5 is rotated along the container conveyance path 4. During the operation of the rotary filling device 1, the liquid filling operation to the container 3 on the container table 5 rotated along the container transport path 4 is performed as follows. First, when the first filling liquid is supplied from the first filling liquid supply source, the first liquid supply pipe 12 is used. At this time, the nozzle switching means 61 is driven to rotate the nozzle head 63 about the rotation support shaft 62, and the first nozzle 7 of the main body 2 of the rotary filling apparatus 1 is moved to the container base as shown in FIG. 5 is set at a position to fill the container 3 above the liquid.

  In this state, the first filling liquid is supplied to the first filling liquid supply port 19 from a liquid supply pipe (not shown) connected to the first filling liquid supply source. Subsequently, the liquid receiving part of the second upper pipe line 17 passes from the straight tubular pipe line 18 of the first fixed part 15 b of the first double pipe 15 through the second upper pipe line 17 of the first double pipe 15. The first filling liquid flows into 17b.

The container 3 is filled with the first filling liquid from the first filling valve 9 through the first nozzle 7.

  Moreover, when performing the liquid change which switches the rotary filling device 1 in production with the first filling liquid to the second filling liquid, the following switching operation is performed. First, the first filling liquid supply source is switched to the second filling liquid supply source. At the same time, the second liquid supply line 13 of the main body 2 of the rotary filling device 1 is switched to a state in which it is used, and the nozzle head 63 is rotationally driven around the rotational support shaft 62 by the nozzle switching means 61. The first nozzle 7 and the second nozzle 8 are switched.

  In this state, the second filling liquid is supplied to the second filling liquid supply port 21 from a liquid supply pipe (not shown) connected to the second filling liquid supply source. Subsequently, the liquid receiving part 16b of the first upper pipe line 16 passes from the bent pipe line 20 of the second fixed part 15c of the first double pipe 15 through the first upper pipe line 16 of the first double pipe 15. The second filling liquid flows into the. Thereafter, the second filling liquid is supplied to the second filling valve 10 of the main body 2 of the rotary filling device 1 through the plurality of second valve pipes 24. As a result, the second filling liquid is supplied from the second filling valve 10 to the container 3 through the second nozzle 8.

  Furthermore, at the time of changing the liquid filling the container 3 from the first filling liquid to the second filling liquid, at the same time, the cleaning operation of the first liquid supply line 12 is performed by the cleaning device 26 as follows. During the cleaning operation of the first liquid supply conduit 12, the first nozzle moving device 39 moves the first nozzle cleaning cup 37 to the cleaning position where the first nozzle 7 is attached. In this state, either the cleaning / disinfecting liquid or the next liquid replacement filling liquid is supplied to the first filling liquid supply port 19.

  Subsequently, after the cleaning liquid is supplied from the first filling liquid supply port 19 to the first filling valve 9 along the same path as the case where the first filling liquid described above is supplied to the first liquid supply pipe line 12, From the 1 filling valve 9, the first nozzle 7 is supplied to the first nozzle cleaning cup 37. The cleaning liquid supplied to the first nozzle cleaning cup 37 subsequently flows into the liquid receiving portion 31b of the first lower pipe 31 through the first waste liquid recovery pipe 33, and then the vertical pipe of the second double pipe 30. The liquid is discharged from the passage 31a to the waste liquid outlet 42 through the first waste liquid pipe 41 of the first fixed portion 30b. Thereby, the cleaning operation of the first liquid supply line 12 can be performed at the same time while the second liquid supply line 13 is used and the container 3 is supplied with the second filling liquid.

  Note that, when the cleaning operation of the second liquid supply pipe line 13 is performed by the cleaning device 26, the second nozzle cleaning cup 38 is moved to the cleaning position where the second nozzle 8 is mounted by the second cup moving device 40. The In this state, it becomes possible to supply the cleaning liquid (for example, the next liquid replacement filling liquid) to the second filling liquid supply port 21.

  Subsequently, the cleaning liquid is supplied from the second filling liquid supply port 21 to the second filling of the main body 2 of the rotary filling apparatus 1 along the same path as the case where the second filling liquid is supplied to the second liquid supply conduit 13. After being supplied to the valve 10, it is supplied from the second filling valve 10 to the second nozzle cleaning cup 38 through the second nozzle 8. The cleaning liquid supplied to the second nozzle cleaning cup 38 subsequently flows into the liquid receiving portion 32b of the second lower pipe 32 through the second waste liquid recovery pipe 35, and then the vertical pipe of the second double pipe 30. The waste liquid is discharged from the passage 32a to the waste liquid outlet 44 through the second waste liquid pipe 43 of the second fixed portion 30c. Thereby, the cleaning operation of the second liquid supply conduit 13 can be performed.

That is, in the rotary filling device 1 of the present embodiment, since two independent liquid supply lines (the first liquid supply line 12 and the second liquid supply line 13) are provided, The nozzles used for production can be selectively switched between the first nozzle 7 and the second nozzle 8. Therefore, by switching between the first nozzle 7 and the second nozzle 8, separately supplied liquids can be selected and used for production, and can be filled without time for liquid change. As a result, the other nozzles can be cleaned while being produced by one nozzle, so that it is not necessary to stop the filling for liquid change and perform the washing, and an efficient production can be achieved.

  In the present embodiment, nozzle switching means 61 is provided in the nozzle support member 2D so that the nozzle used for filling the container 3 can be switched between the first nozzle 7 and the second nozzle 8. Therefore, as the air cylinder 64 of the nozzle switching means 61 is driven, the nozzle head 63 is rotationally driven about the rotational support shaft 62 as shown by the arrow in FIG. It is possible to switch between a state where either one is selectively used and a state where both are used together. Thereby, it is applicable to various production with one machine.
