When the plugging is completed, the cap is raised, shifted, and returned to the original position (decap position). . When the capping device is completed, the second spout jig 110 is opened while the capping device returns to the original position, and is forcibly ejected by the inclined ejection drive roller conveyor 80. At the same time, the next bag is spouted by the forward movement of the pusher. Supplied to the tool. Then, liquid filling is started again. Immediately after the start of the filling, a part of the perforation 13 connected to the filled bag that has been forcibly discharged is cut and separated by the cutter 70 shown in FIGS. 11 and 12, conveyed by a driving roller conveyor for discharging, and provided at the top of the boxing device. And is stored in an outer box 85 such as a cardboard case.

In the present invention, filling is performed while being measured by an electromagnetic flow meter 90, and shortly before the filling amount reaches a fixed amount, the filling nozzle valve 43 descends as shown in FIG. The liquid adhering to the tip of the filling nozzle is sucked by a vacuum device such as a water ring vacuum pump through the suction pipe 44.

Further, before filling the bag with the liquid, the air in the bag is evacuated from the tip of the filling nozzle in the same manner as described above, and when filling the bag with the liquid, the air is provided below the bag as shown in FIGS. The back lifter 60 shown in FIG. 8 is filled while supporting the weight of the liquid product, thereby preventing air from getting into the bag. Except for the back insertion and discharge parts, the filling device body covers the whole and has a substantially closed structure. A hepa filter 91 is provided at the top, and clean air is blown down into the device to allow outside air to enter the filling part. The structure is such that the liquid product can be prevented from being sanitized.
