Abstract: An article carrier includes a first supply wheel adjacent to a receiving wheel and a second supply wheel provided on the upstream side in the rotating direction of the receiving wheel from the first supply wheel. A switching device for switching a gripper of the first supply wheel between a use state so as to transfer a plastic bottle to a gripper of the receiving wheel and a retracted state so as not to interfere with the plastic bottle held by the gripper of the receiving wheel is also provided. When a first carrier path is used, the switching device brings the gripper of the first supply wheel into the use state, and when a second carrier path is used, the switching device brings the gripper of the first supply wheel into the retracted state.

Abstract: The present invention includes a first supply wheel 11 adjacent to a receiving wheel 13, and a second supply wheel 12 provided on the upstream side in the rotating direction of the receiving wheel from the first supply wheel. Switching means 17 for switching a gripper A of the first supply wheel between a use state so as to transfer a plastic bottle 1 to a gripper C of the receiving wheel and a retracted state so as not to interfere with the plastic bottle held by the gripper of the receiving wheel is also provided. When a first carrier path is used, the switching means brings the gripper of the first supply wheel into the use state, and when a second carrier path is used, the switching means brings the gripper of the first supply wheel into the retracted state, to thereby prevent the gripper of the first supply wheel from interfering with the article held by the gripper of the receiving wheel from the second supply wheel. The carrier paths can be thereby quickly switched.

Abstract: A beverage filling method and an apparatus to perform the beverage filling method, wherein a liquid is delivered from a storage tank into a filler tank of a filler, and the liquid is filled into containers by the filler. The method is characterized in that the liquid in the filler tank is returned through return piping attached to the filler tank and refluxed to the storage tank through a reflux path. According to this method, an excess of liquid in the filler can be circulated throughout the entire line.

Abstract: A vessel mouth gasket unit is fitted around the outer periphery of a valve body which is internally formed with a filled liquid passage. A first gasket having a smaller diameter and a second gasket having a larger diameter is mounted on the lower surface of the unit. The filling valve is made up of a liquid valve opening and closing air cylinder which opens and closes a liquid valve 8 disposed in the filled liquid passage, and a vessel mouth gasket auxiliary air cylinder which urges the unit downward. The valve body has an outer diameter which is greater than the aperture diameter of a bottle-like first type vessel and less than the aperture diameter of a second type vessel having a larger aperture. The operating pressure of the auxiliary air cylinder is controllable and the filling operation takes place by urging the gasket against the first vessel with a low load and by urging the gasket against the second type vessel with a high load.

Abstract: A filling apparatus 1 is made up of a gas passage 14 connected to a storage tank 31 via a connection passage 14a, a first gas valve 35 that opens and closes the gas passage, a pressure gas passage 41 connected to a pressure gas supply source, a pressure gas valve 42 that opens and closes the pressure gas passage, an exhaust passage 43 that allows an interior of a container 4 to communicate with the exterior thereof, and an exhaust valve 44 that opens and closes the exhaust passage. With this filling apparatus, before a pressurized filling operation, both the gas passage and the pressure gas passage are opened to pressurize the interior of the container with a carbonated gas supplied through both passages. Further, also before a unpressurized filling operation, both the gas passage and the pressure gas passage are opened to perform a flushing operation in which droplets are discharged from the gas passage with air exhausted from the container into the storage tank via the gas passage.
