Abstract
Weighing and filling apparatus for controlling filling device based on a container weight. A linear actuator for driving a drive shaft coupled to container support unit is included, a weight measuring unit determines the container weight from a detected height of the drive shaft detected by a height detecting unit and a drive signal of the linear actuator at the detected height. A first acceleration signal is calculated from a specified height of the container support unit set in advance and the height detected by the height detecting unit, a second acceleration signal is calculated from the container weight and an expected weight expected to be applied to the container support unit. The container support unit is kept at the specified height by a drive signal calculated from the first and second acceleration signals.
