Since the positioning part can be arranged in the lowered position where it can be engaged with the filling port of the bottle, the filling port of the bottle can be surrounded by the guide ring of the positioning part, and the filling port is accurately positioned at the filling position of the filling nozzle. can do. As a result, the positioning accuracy of the bottle can be accurately maintained for a long period of time, and the reliability can be improved, as compared with the case where a positioning member made of a rubber material is used as in the prior art.

According to the third aspect of the present invention, at the supply position and the discharge position, the tip end side of the rotating arm of the elevating mechanism is turned upward by the cam plate to raise and lower the tip end side of the rotating arm of the positioning member. The positioning portion can be pushed up by engaging the plate portion from the lower side, and can be arranged in the raised position. When the lifting mechanism is out of the supply position and the discharge position, the tip end side of the rotating arm is rotated downward by the biasing force of the spring member, and the lifting plate portion of the positioning member is lowered to move the positioning portion to the lowered position. By arranging, the guide ring can be engaged with the filling port of the bottle, and the bottle can be positioned.

On the other hand, when changing the bottle to another bottle having a different height, the elevating plate portion of the positioning member is supported on the tip end side of the rotating arm of the elevating mechanism, and in this state the height adjusting mechanism. By elevating the elevating / lowering rotary body by using, the height distance between each filling nozzle and each positioning member can be adjusted at the same time, and the positioning portion of each positioning member can be easily adjusted according to the height dimension of the bottle. Therefore, the workability can be improved. Moreover, since it is not necessary to prepare various replacement parts for each height dimension of the bottle, it is possible to reduce the cost of replacement parts and reduce the cost.
