Title:
WEIGHING AND FILLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/216144
Kind Code:
A1
Abstract:
The present invention relates to a weighing and filling device 3 which controls a filling means 6 on the basis of a container weight measured by a weight measuring means. The weighing and filling device is provided with a linear actuator 12 which drives a drive shaft 11 coupled to a container support means 5. A weight measuring unit 9a (weight measuring means) obtains the container weight from a detected height of the drive shaft 11 detected by a height detecting means 13, and a drive signal of the linear actuator 12 at the detected height. The weighing and filling device calculates a first acceleration signal from a predetermined specified height of the container support means 5, and the detected height detected by the height detecting means 13, calculates a second acceleration signal from the container weight obtained by the weight measuring unit 9a and an assumed weight assumed to be acting on the container support means 5, and maintains the container support means 5 at the specified height by means of a drive signal calculated from the first and second acceleration signals. The container weight can be measured rapidly, and trouble when delivering the container can be prevented as far as possible.
