Method and apparatus for filling liquid into containers
First Claim
1. An apparatus for filling a predetermined weight of a liquid sequentially into each of a plurality of containers such as bottles, cans, or the like, said apparatus comprising:
- a metering container having a liquid inlet for receiving liquid and a liquid outlet for discharging liquid;
weighing balance means, having placed thereon said metering container, for determining the weight of said metering container and any liquid therein and for generating signals representative thereof;
liquid feed control valve means, connected to said liquid inlet with a flexible pipe therebetween, for controlling the supply of liquid into said metering container;
liquid filling control valve means, connected to said liquid outlet with a flexible pipe therebetween, for controlling the discharge of liquid from said metering container;
conveyor means for sequentially positioning the containers beneath said liquid filling control valve means; and
control unit means, operatively connected to said weighing balance means and to said liquid feed control valve means and said liquid filling control valve means, for, in response to said signals generated by said weighing balance means, opening and closing said liquid feed control valve means to thereby regulate the weight of liquid supplied into said metering container, and opening and closing said liquid filling control valve means to thereby regulate the weight of liquid discharged from said metering container into a container positioned by said conveyor means beneath said liquid filling control valve means.

Abstract
A predetermined amount of liquid is to be filled into a container. The weight of liquid contained within a metering container is measured by a balance and a filling control valve provided at an outlet of the metering container is controlled in response to a signal issued from the weighing balance. Thereby a predetermined amount of the liquid can be filled from the metering container into the container. A control unit opens and closes the filling control valve and a feed control valve connected to a liquid feed source in response to a signal issued from the weighing balance. An inlet of the metering container is connected via a flexible pipe to an outlet of the feed control valve, and an outlet of the metering container is connected via a flexible pipe to an inlet of the filling control valve.

4. A method for filling a predetermined weight of a liquid sequentially into each of a plurality of containers such as bottles, cans, or the like, said method comprising:
-
providing a metering container, having a liquid inlet and a liquid outlet, placed on a weighing balance, and thereby determining the weight of said metering container and any liquid therein, and generating signals representative thereof; providing a liquid feed control valve connected to said liquid inlet with a flexible pipe therebetween for controlling the supply of said liquid into said metering container, and providing a liquid filling control valve connected to said liquid outlet with a flexible pipe therebetween for controlling the discharge of said liquid from said metering container; sequentially positioning said plurality of containers beneath said liquid filling control valve; and controlling, in response to said signals generated by said weighing balance, opening and closing of said liquid feed control valve and thereby regulating the weight of said liquid supplied into said metering container, and opening and closing of said liquid filling control valve and thereby regulating the weight of said liquid discharged from said metering container into each said container positioned beneath said liquid filling control valve. - View Dependent Claims (5, 6)
