Abstract
A liquid metering-filling apparatus is provided which includes a container transport conveyor intermittently drivable so as to halt containers one by one at a filling station. A filling nozzle is disposed above a path of transport of containers at the filling station. A metering cylinder houses a piston and has an outlet in communication with the filling nozzle. An inlet check valve is provided at an inlet of the metering cylinder. An outlet check valve is provided at any one of the outlet of the metering cylinder and inside of the filling nozzle. The liquid metering-filling apparatus also includes a driver for causing the piston to perform a cycle of stroking movement every time the conveyor is driven by one pitch. A photoelectric sensor is provided at the filling station for detecting any one of the presence and absence of a container of the plurality of containers at the filling station. A photoelectric sensor is provided at a stop station for detecting any one of the presence and absence of a container of the plurality of containers at the stop station which is immediately preceding the filling station upstream therefrom. The liquid metering-filling apparatus also includes a va…
