Abstract
A rotary type continuous filling apparatus that continuously fills bags accommodated in retainers with a filling liquid via filing nozzles. A cylinder of each of the pump devices that correspond to the respective filling nozzles is installed horizontally with the discharge opening facing outward. The discharge opening communicates with a feed-out opening of a nozzle main body, and a tank containing the filling liquid communicates with a supply opening of the nozzle main body via a flow passage. A cam roller is connected to the piston via swing levers, vertical supporting shafts and cam levers, and these cam rollers move along an annular cam groove of a piston operating cam. Furthermore, each filling nozzle has a flow passage switching valve that switches between a communication and non-communication of the supply opening and the feed-out opening, and it also has an opening-and-closing valve that opens and closes the discharge port.
