A process and device for filling a vessel with a liquid. The vessel is placed on a lifting plate and guided up to a filler spout a predetermined distance measured from its base, the vessel's opening being lifted into a sealed filling position below the filler spout. The vessel is filled up to a predetermined filling level by opening a valve associated with the filler spout, whereupon the supply of liquid is terminated, and a volume of liquid still present between the valve and the filling level flows into the vessel. This after-flowing liquid volume is controlled as a function of the vessel height so that in the case of a vessel having a height smaller than a mean vessel height there is an afterflow of a larger volume of liquid than in the case of a greater vessel height where the afterflow is of a smaller volume of liquid.
A method for controlling the total volume of a liquid fed to vessels of varying height in a filling machine for filling the vessels with a liquid, said vessels having a base at a bottom end, an opening at a top end and a mean height as measured from said bottom end, said filling machine having a fixed filler spout for receiving the opening of the vessel in a sealed filling position and a liquid flow valve for controlling the flow of liquid through said spout into said vessel, said method comprising lifting each vessel up toward said filler spout so that its base is a constant distance from the filler spout and its opening is in said sealed filling position below the filler spout, opening the liquid control valve and filling the vessel with the liquid to a predetermined filling level in the vessel measured from its base, thereafter closing the liquid control valve to terminate the flow of liquid to the vessel, an afterflow volume of liquid remaining between said filling level and the valve after the valve is closed, and controlling said afterflow volume of the liquid as a function of the height of the vessel such that the afterflow volume of a vessel having a height more than said mean height is smaller than the afterflow volume for said mean height vessel and for a vessel having a height less than said mean height, the afterflow volume is greater than the afterflow volume for said mean height vessel.
A device for controlling the total volume of a liquid fed to vessels of varying height in a filling machine for filling the vessels with a liquid, said vessels having a base at a bottom end, an opening at a top end and a mean height as measured from said bottom end, said device comprising a filler spout fixedly mounted on said filling machine adapted to receive the opening in the top of a vessel in a sealed manner, a liquid flow valve for controlling the flow of liquid through said spout, lifting means for lifting a vessel toward said filler spout to bring said opening into a sealed filling position with respect to the filler spout with its base being a constant distance from the filler spout, control means for operating the valve to fill each vessel to a predetermined filling level measured from its base, an afterflow chamber being formed between said level and said valve containing an afterflow volume of liquid after said filling level has been reached and means for varying the volume of said chamber as a function of the height of the vessel such that the volume of the chamber is smaller for a vessel having a height more than said mean height than the volume of the chamber is for a mean height vessel and is larger for a vessel having a height less than said mean height than volume of the chamber is for a mean height vessel.
