In the following, the present invention will be described in detail with reference to the drawings.
In FIG. 1 and FIG. 2, the filler 1 for filling drink liquid of the present invention is such a type that container 2, such as barrel of beer is kept upside-down, and drink liquid, such as beer, soft drink etc., is filled through cap 3 from the lower part, and is composed of cylinder rod 4 connected to cap 3, discharge hole 7 longitudinally penetrated through a center of cylinder rod 4, stay portion 5 secured at the upper part of the periphery of cylinder rod 4, through which the drink liquid passes, and supply pipe 6 for drink liquid connected to stay portion 5. Each of stay portion 5 and discharge hole 7 is respectively connected into the inside of the container 2 by pushing up cylinder rod 4 and opening the cap 3 of container 2, and drink liquid is filled up into container 2 from supply pipe 6. At the same time, the air in container 2 is discharged through discharge hole 7. On supply pipe 6, storage equipment 12 for stayed liquid having storage room 18 is secured, and on stay portion 5, pipe 11 for introducing pressurized air is secured to be connected to stay portion 5 through discharge hole 7. As a result, stay portion 5 and exhaust hole 7 are both shut off from the inside of container 2 by pulling down cylinder rod 4 and closing the cap 3 of container 2, and then, the pressurized air is introduced into stay portion 5 from pipe 11 for pressurized air, and the stayed liquid in stay portion 5 is introduced into storage room 18 through supply pipe 6. Discharge hole 7 is connected to discharge line 8 and pipe 11 for pressurized air. Numeral 10 is air discharge pipe.
The characters of the present invention reside in securing storage equipment 12 for stayed liquid on the optional point of supply pipe 6, connecting stay portion 5 to supply pipe 6 and to pipe 11 for introducing pressurized air through discharge hole 7, closing cap 3 of container 2 by pulling down cylinder rod 4, and thereafter, introducing pressurized air into stay portion 5 from pipe 11 for introducing pressurized air through discharge hole 7, and sending stayed liquid of stay portion 5 to storage equipment 12 for stayed liquid through supply pipe 6.
The afore-mentioned filler 1 for filling drink liquid is operated as follows. At first, empty container 2 before filling is carried with a carrying machine not shown in the drawings, and after then, cylinder rod 4 is pushed up as shown in FIG. 3 to open cap 3 of container 2, and at the same time, to connect stay portion 5 to container 2. FIG. 1 is a cross section showing the state of opening cap 3 of filler 1 for filling drink liquid. Next, control valve 13 for drink liquid, control valve 14 for discharge air and control valve 15 for stayed liquid are all, opened, and as a result, supply pipe 6 for drink liquid is connected into the inside of container 2, and drink liquid is introduced and filled into container 2 toward the direction shown by an arrow through supply pipe 6 and stay portion 5 from supply source not shown in the drawings. At the same time, the air in container 2 is discharged from container 2 toward the direction of an arrow through pipe 10 for discharging air in container 2, discharge hole 7 longitudinally penetrated through a center of cylinder rod 4, and discharge line 8. At this time, stay portion 5 is occupied with drink liquid during the filling.
When the filling is reached to desired amounts, control valve 13 for drink liquid of supply pipe 6, control valve 14 for discharge gas of discharge line 8, and control valve 15 for stayed liquid are respectively closed. Thereby, the filling of drink liquid to container 2 is finished. At the same time, cap 3 of container 2 is shut by pulling down cylinder rod 4, thereby, the inside of container 2 is separated from filler 1 for filling drink liquid.
After then, control valve 13 for drink liquid and control valve 16 for pressurized air are both opened, and pressurized air is introduced into stay portion 5 in which the stayed liquid is stayed, through discharge hole 7 from pipe 11 for introducing pressurized air, and as a result, the stayed liquid in the stay portion 5 is pushed out to supply pipe 6, and finally is carried out to storage room 18 of storage equipment 12 for stayed liquid.
The storage equipment 12 is composed, as shown in FIG. 1, by storage room 18, driving device 19, such as air cylinder, connected on the top of storage room 18, and diaphragm 17 arranged on opening 20 for introducing stayed liquid, which is opened toward supply pipe 6. The storage room 18 is covered with diaphragm 17 as shown in FIG. 1, before the pressurized air is introduced into the discharge hole 7. When the stayed liquid is pushed out to the supply pipe 6 by the pressurized air, the diaphragm 17 is pushed up to the roof of the storage room 18 as shown in FIG. 2 by the operation of air cylinder 19 and the pressure of pressurized air, and the storage room 18 is opened. At this time, the stayed liquid is introduced and recovered into the storage room 18 in a direction shown by an arrow with the pressure of the pressurized air.
When the recovery of the stayed liquid is finished, the control valve 13 for drink liquid and the control valve 16 for pressurized air are closed. Thereby, the stayed liquid is tightly preserved in the storage room 18 of the storage equipment 12 for stayed liquid with keeping the pressure necessary for the quality of a liquid product. And the container 2 is removed from the filler 1 for filling drink liquid, and is transported with carrying machine not shown in the drawings. After then, next empty container is set up to the filler 1 for filling drink liquid in the same manner, and the filling operation starts in the same manner. At this time, the drink liquid preserved in the storage equipment 12 for stayed liquid is used in the next filling.
The driving device 19 driving the diaphragm 17 of the storage equipment for stayed liquid can be an operating spring 21 as shown in FIG. 5. Also, it can be a valve 22 for adjusting pressure as shown in FIG. 6. Further, the storage room 18 of the storage equipment 12 for stayed liquid can be composed by piston room 23 as shown in FIG. 7, and the stayed liquid in the storage room 18 of the storage equipment 12 for stayed liquid can be inhaled or discharged by driving piston 24 in the piston room 23 with driving device 19, such as air cylinder.
The filler for filling drink liquid of the present invention is composed by arranging the storage equipment for stayed liquid on the supply pipe, and introducing the stayed liquid stayed in the stay portion into the storage equipment for stayed liquid through the supply pipe. And accordingly, it can accomplish the advantages of recovering the stayed liquid without a dropping of the quality, and economically re-used by mixing with the drink liquid from a supply resource not shown in drawings during the filling. Then, the present filler is preferably utilized in the factories for drink liquid, such beer brewery, soft drink manufacturing, etc.
