(Function)
Next, the operation of the above configuration will be described. During the operation of the rotary filling device 1 according to the present embodiment, the rotary table 2B is rotated with respect to the fixed base 2A of the main body 2 of the rotary filling device 1 to thereby support the shaft portion 2C provided on the rotary table 2B. The nozzle support member 2D, the nozzles 7 and 8, the rotating unit 15a of the liquid supply device 11, and the rotating unit 30a of the cleaning device 26 are rotated together with the rotation of the rotary table 2B. Further, the members attached to these are similarly rotated together with the rotation of the turntable 2B.

  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 first nozzle 7 of the main body 2 of the rotary filling device 1 is set at a position where the container 3 on the container table 5 is filled with 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. Thereafter, the first filling liquid is supplied to the first filling valve 9 of the main body 2 of the rotary filling device 1 through the plurality of first valve pipes 22. When the container table 5 flowing through the container conveyance path 4 reaches a predetermined filling liquid supply position in a state synchronized with the flow of the container 3 on the container table 5 conveyed along the container conveyance path 4. The first filling liquid is supplied from the first filling valve 9 to the container 3 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 where it is used, and 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.

(effect)
Therefore, the above configuration has the following effects. 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.

  Furthermore, since liquids having particularly different liquidity can be provided with different systems of piping, it is possible to prevent the smell and color transfer of the filling liquid, and to prevent foreign matters from being mixed in from another filling liquid. Therefore, the quality of the product liquid filled in the container 3 on the container transport path 4 can be stabilized.

  In addition, a cleaning device 26 for cleaning each liquid pipe of the liquid supply device 11 is provided below the main body 2 of the rotary filling device 1, and two cup moving devices (a first cup moving device 39 and a second cup moving device 40) are provided. ), The first nozzle cleaning cup 37 and the second nozzle cleaning cup 38 are movably supported at the cleaning position (see FIG. 7) and the standby position (see FIG. 6), respectively. As a result, at the time of cleaning in which the waste liquid from the first nozzle 7 is discharged from the first waste liquid recovery pipe 33 for cleaning, the nozzle 7 and the waste liquid recovery pipe 33 are connected by the operation of the first cup moving device 39. The first nozzle cleaning cup 37 is moved to the position. Similarly, at the time of cleaning in which the waste liquid from the second nozzle 8 is discharged from the second waste liquid recovery pipe 35 for cleaning, the nozzle 8 and the waste liquid recovery pipe 35 are connected by the operation of the second cup moving device 40. The second nozzle cleaning cup 38 is moved to the position. Therefore, during the production using one of the two nozzles (the first nozzle 7 and the second nozzle 8) of the main body 2 of the rotary filling device 1, the other nozzle can be cleaned at the same time. . As a result, while producing using one nozzle and the liquid supply path connected to the same nozzle, the liquid supply path connected to the other nozzle and the same nozzle can be cleaned at the same time. Efficient production is possible without requiring time.

  Furthermore, since the pattern of the cleaning process can be changed according to the situation, for example, when the next liquid replacement filling liquid is used as a cleaning liquid for the co-cleaning cleaning, a cleaning time for liquid replacement is required. Therefore, the production amount can be increased. This makes it possible to use dedicated piping for filling liquids such as strong-fat oils (roasted sesame oil, olive oil, etc.) that are difficult to clean and oils with high melting points (palm oil, palm kernel oil, coconut oil, etc.) that easily solidify at room temperature. The product of the main body 2 of the rotary filling apparatus 1 during the operation of filling the container 3 with the product liquid from one of the nozzles of the main body 2 of the rotary filling apparatus 1 and producing it in one of the liquid supply pipes Waste liquid from other nozzles that are not filled with liquid can be washed from the waste liquid conduit by washing the waste liquid from the first nozzle 7 and the second nozzle 8 for each filling liquid supply source. The waste liquid can be drained without being mixed from the waste liquid pipes (second waste liquid pipe 27 and first waste liquid pipe 28) corresponding to different paths, and the two systems of filling pipes can be washed simultaneously.

  In general, when the filling liquid is solidified in the exposed pipe, the pipe is heated from the outside to be dissolved. Alternatively, a method of disassembling and cleaning the piping is used, but it is difficult to heat the piping inside the apparatus from the outside, and disassembling is a large-scale operation.

  In the present embodiment, the first double pipe 15 is provided in the liquid supply device 11 at the top of the main body 2 of the rotary filling device 1. And one of the two pipe lines (the first upper pipe line 16 and the second upper pipe line 17) of the first double pipe 15 arranged coaxially (for example, the first upper pipe) For example, palm oil (melting point: 27-50 ° C.), palm kernel oil (melting point: 25-30 ° C.), palm oil (melting point: 20-28 ° C.), etc. When solidified in the pipe, a high-temperature heating in the second upper pipe 17 is caused by flowing a high-temperature heating liquid (filling liquid) through the other pipe (for example, the second upper pipe 17). The edible oil having a high melting point in the first upper pipe line 16 can be heated and dissolved by the heat of the liquid through the pipe wall of the first double pipe 15. Therefore, there is an effect that the filling liquid of edible oil having a high melting point in the first upper pipeline 16 can be easily prevented and dissolved.

  In addition, the other liquid supply pipe can be obtained by allowing the warming / warming liquid to flow through one of the two independent liquid supply lines (the first liquid supply line 12 and the second liquid supply line 13). It is also possible to prevent solidification of the filling liquid or cleaning liquid of the passage. In this case, one of the two independent liquid supply lines (the first liquid supply line 12 and the second liquid supply line 13) is provided by an existing heating device (hot water device, steam device, etc.). It is easy to heat and control the temperature.

  Moreover, in this Embodiment, the 2nd double piping 30 which is not exposed outside is provided in the washing | cleaning apparatus 26 of the lower part of the main body 2 of the rotary filling apparatus 1. FIG. Of the two pipes of the second double pipe 30 (the vertical pipe 31a and the liquid receiving part 31b of the first lower pipe 31 and the vertical pipe 32a and the liquid receiving part 32b of the second lower pipe 32) For example, palm oil (melting point: 27 to 50 ° C.), palm kernel oil (melting point: 25 to 30 ° C.), or the like (for example, the vertical pipe 31 a and the liquid receiving portion 31 b of the first lower pipe 31), When edible oil having a high melting point such as coconut oil (melting point: 20 to 28 ° C.) is dissolved and the remaining edible oil in the pipe is solidified, the other pipe (for example, the vertical pipe of the second lower pipe 32) 32a and the liquid receiving part 32b), the hot liquid (filling liquid) is allowed to flow through the vertical pipe line 32a of the second lower pipe 32 and the heat of the hot liquid in the liquid receiving part 32b. Melting points in the vertical pipe line 31a and the liquid receiving part 31b of the first lower pipe line 31 through the pipe wall of the second double pipe 30 It can be dissolved by heating high edible oil. Therefore, there is an effect that the filling liquid of edible oil having a high melting point in the vertical pipe line 31a and the liquid receiving part 31b of the first lower pipe line 31 can be easily prevented and dissolved. It is to be noted that the warming / warming liquid is allowed to flow through one of the two waste liquid pipes (the first waste liquid pipe 28 and the second waste liquid pipe 27), thereby filling or cleaning liquid in the other waste liquid pipe. It is also possible to prevent solidification. In this case, it becomes possible to clean the pipeline without disassembling the peripheral portion of the second double pipe 30 that is not exposed to the outside at the lower part of the main body 2 of the rotary filling device 1, thereby simplifying the cleaning process. Simplification can be realized.
