Then transported. The PET bottle 4 whose inner surface and outer surface have been cleaned by an upstream rinser (not shown) is transferred from the intermediate wheel 6 to the supply wheel 8 and supplied to the rotary filling device 2 via the supply wheel 8. Is done.

  First, the case where gas filling is performed will be described. A plurality of filling means 12 are provided on the outer peripheral portion of the rotary body 10 of the rotary filling device 2 at equal intervals in the circumferential direction. A neck gripper 14 and a flange receiving guide are respectively provided below the filling means 12. 68, a container holding means 13 having a mouth guide 72, a support plate 80, and the like are arranged. The PET bottles 4 supplied from the supply wheel 8 are delivered to the container holding means 13 one by one. As shown in FIG. 3, both grip members 14 </ b> A and 14 </ b> B constituting the neck gripper 14 are inclined on the front surfaces 14 </ b> Ab and 14 </ b> Bb and are held by container holding means (not shown) of the supply wheel 8. When the PET bottle 8 is pressed against the inclined surfaces 14Ab and 14Bb of the grip members 14A and 14B at the supply position A, both grip members 14A and 14B fixed to the both side portions 66a and 66b of the leaf spring 66 are expanded. Then, the PET bottle 4 is pushed in.

  When the thickest portion of the neck portion 4a of the PET bottle 4 passes through the front ends 14Ac and 14Bc of the engaging portions 14Aa and 14Ba of the grip members 14A and 14B, the grip members 14A and 14B are restored to the original state by the spring force of the leaf spring 66. Then, the outer surface side of the neck portion 4a of the PET bottle 4 is held. The neck portion 4a of the PET bottle 4 is supported on the lower surface side of the flange 4b by the arc-shaped flange receiving guide 68, and on the radially inner side of the rotating body 10 above the flange 4b. The plate 80 and the mouth guide 72 are arranged, and the gripper 14, the flange receiving guide 68, the support plate 80 and the mouth guide 72 jointly grip the PET bottle 4. The mouth portion guide 72 is urged radially outward of the rotating body 10 by a spring 78. By pressing the upper portion of the neck portion 4a, the flange 4b is pressed against the horizontal portion 68b of the flange receiving guide 68, and PET. The bottle 4 is maintained in a vertical posture.

  When the PET bottle 4 is delivered from the supply wheel 8 to the container holding means 13, the packing unit elevating cylinder 48 is operated to lower the packing unit 46. When the packing unit 46 is lowered, the bottle mouth packing 52 provided at the center thereof is pressed against the mouth upper end 4c of the PET bottle 4 held in the vertical state by the container holding means 13. Since the lower surface of the bottle opening packing 52 is inclined so that the center side of the rotating body 10 is low and the outer side is high, the PET bottle 4 is inclined with the bottom 4d facing outward in the radial direction of the rotating body 10. While the PET bottle 4 is held by the container holding means 13 and is in a vertical posture, the flange 4 b of the PET bottle 4 is placed on the horizontal portion 68 b on the front end side of the flange receiving guide 68. When pressed from above, it is pressed against the substantially semicircular inclined surface 68a and is stably held in an inclined posture between the bottle packing 52 and the flange receiving guide 68, and the inside of the PET bottle 4 Is sealed (state shown in FIG. 7).

  As described above, the inside of the PET bottle 4 is sealed by pressing the bottle packing 52 against the upper end 4c of the PET bottle 4 held by the container holding means 13, and then the open / close valve 56 and the snift of the counter passage 54 are sealed. The open / close valve 60 of the passage 58 is opened to introduce the pressurized counter gas into the PET bottle 4 and discharge the air in the PET bottle 4 from the sniff passage 58. After a predetermined time has elapsed, the opening / closing valve 56 of the sniff passage 54 is closed, and the liquid valve 30 is opened to start filling. The PET bottle 4 is filled with a liquid, and the pressurized gas introduced into the PET bottle 4 is discharged from the counter passage 58. When it is measured that a predetermined amount of liquid is filled by the flow meter 40 provided in the liquid supply pipe 28, the liquid valve 30 is closed by a command from a control device (not shown), and the filling is finished.

  After that, the sniffer passage 58 is opened for a predetermined time, and the pressurized gas in the head space of the PET bottle 4 is discharged, and then the bottle packing 52 is raised by the packing unit elevating cylinder 48. When the pressing force from above is removed, the PET bottle 4 filled with the liquid is pushed from the radially inner side by the mouth guide 72 on the upper side of the flange 4b, and is returned to the upright state and conveyed. When it reaches the discharge position B with the rotation of the rotating body 10, it is delivered to a gripper (not shown) of the delivery wheel 16 and sent to the next capper 18. The PET bottle 4 capped by the capper 18 is discharged to the transport conveyor 22 via the discharge wheel 20 and sent to the next step. In this embodiment, since the PET bottle 4 is filled with the bottom portion 4d held in the radially outward direction of the rotating body 10, the filling liquid discharged from the filling means 12 is rotated by the rotation of the rotating body 10. Even if it is shaken to the outer side in the radial direction of the rotating body 10 by the generated centrifugal force, it can be applied to almost the center of the bottom 4d of the PET bottle 4 and foaming at the time of filling can be suppressed. Moreover, since foaming can be suppressed, the filling capacity can be increased. As a result, the number of necessary filling means can be reduced and the size of the apparatus can be reduced.

  Next, the case of non-gas filling in which a liquid not containing gas is filled will be described. The PET bottles 4 supplied from the supply wheel 8 are delivered to the container holding means 13 one by one. The flange 4b of the PET bottle 4 is placed on the horizontal portion 68b of the flange receiving guide 68, and the PET bottle 4 is supported in an upright posture (state shown in FIG. 2). In the case of non-gas filling, filling is performed with the bottle opening packing 52 in the raised position. In this state, a gap is formed between the upper end surface 4c of the mouth portion of the PET bottle 4 and the lower surface 52a of the upper bottle mouth packing 52, and filling is performed in a state where the inside of the PET bottle 4 is opened. At the time of non-gas filling, the PET bottle 4 can be stably supported by pressing the lower surface of the flange 4b against the horizontal portion 68b by the mouth guide 72.

  In the case of non-gas filling, the open / close valves 56 and 60 provided in the counter passage 54 and the sniffer passage 58 are always closed. The PET bottle 4 is supplied to the container holding means 13, and the PET bottle 4 and the upper filling means 12 rotate in a state where the upper and lower positions coincide with each other, and a predetermined position on the transport path of the PET bottle 4 by the rotation of the rotating body 10. Then, an air cylinder for opening and closing a liquid valve (not shown) is operated to raise the rod 32 and open the liquid valve 30. The filling liquid supplied from the filling liquid tank to the filling liquid passage 26 in the valve housing 24 through the liquid supply pipe 28 passes through the liquid valve 30 and the discharge port 44 below the filling liquid tank 30 and fills the PET bottle 4. (State shown in FIG. 2). The filling liquid passing through the liquid supply pipe 28 is measured by a flow meter 40, and the liquid valve 30 is closed when a predetermined liquid amount is measured. In the above embodiment, the packing unit 46 is moved up and down to bring the bottle mouth packing 52 and the upper end 4c of the PET bottle 4 into close contact with each other. However, the neck gripper 14 may be moved up and down. Moreover, in the said Example, although the flange receiving guide 68 was provided independently of the neck gripper 14, the surface which supports the flange 4b can also be provided in the neck gripper 14.
