DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE ART

The invention refers to the technological field of bottling, generally known in the international classification B67c, and in particular to the volumetric filling devices.


STATE OF THE ART

In the literature of prior art are described several types of metering devices (for example patent EP A1 0262258) in which the volumetric chamber includes a mobile cover, sliding inside the transfer chamber, and equipped with o-ring seals.
In the patent EP A1 0470398 is shown a piston inside a metering chamber, and the movements of which, are controlled by an actuating rod, exiting from the chamber, equipped with o-ring seals.
Furthermore, in all known systems, the capacity of the volumetric chamber of the metering filling devices, is pre-set and regulated, by movements of a piston inside the volumetric chamber. Said movements are actuated by rods that exit to be connected to the cinematic systems. Such rods need to be equipped with o-ring seals at the exit orifice. These o-rings are known to cause problems during the sanitation and cleaning in place.
The problem yet to be solved is the realization of a device to actuate the movements of a sliding body inside the volumetric chamber without employing mechanical devices going through the hermetic cover of said filling chamber.
This problem is solved by the present invention as defined in the appended claims. The solution proposed, is to employ a system with permanent magnets, which allows to move from the outside a body suspended inside the hermetic chamber.
The forces needed to move the inside body can be transferred without contact, using the magnetic fields through the walls of the volumetric chamber.
Furthermore, the running slack fit of the inside body, is utilized to allow the flow of the processing fluids without the use of the traditional venting tube.


BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be better understood from the following detailed description of a preferred embodiment of the invention, taken in conjunction with the accompanying drawings, in which like reference numerals refer to like parts, and in which:
FIG. 1 is a partial cross-sectional view of a metering apparatus according to a preferred embodiment of the invention, showing the start of a transfer phase of the filling liquid from a main feeding tank into a volumetric chamber;
FIGS. 2 and 3 are views similar to FIG. 1 showing the continuing flow of liquid during the transfer phase;
FIG. 4 is a view similar to FIGS. 1 to 3 showing the end of the transfer cycle;
FIG. 5 is a view similar to FIGS. 1 to 4 illustrating the start of a delivery cycle in which liquid in the volumetric chamber is transferred to a bottle;
FIG. 6 is a view similar to FIG. 5 illustrating the continuing of the delivery cycle;
FIG. 7 is a view similar to FIGS. 5 and 6 illustrating the completion of the delivery cycle in which the bottle is filled;
FIG. 8 is a schematic top view of a rotating filler assembly;
FIG. 9 is a view similar to FIG. 4 illustrating the end of a delivery cycle for filling bottles of smaller capacity than those of FIGS. 5 to 7; and
FIG. 10 is a partial cross-sectional view of the apparatus illustrating a cleaning operation.


DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1 to 7 illustrate a metering apparatus according to a preferred embodiment of the present invention for supplying predetermined quantities of a liquid 16 to a bottle or other container, and also illustrate successive steps in a filling operation. The metering apparatus basically comprises a vertically orientated metering cylinder 4 having an inner wall defining a volumetric chamber 3, and a free-hanging metering device 1 slidably mounted in chamber 3 for controlling the amount of liquid supplied to chamber 3, as described in more detail below.
The lower end of the chamber 3 is connected via passageway 30 to the lower end of a main filling tank 32, and a cut-off valve 12 is provided in passageway 30. The upper end of the chamber 3 is connected via connecting pipe 11 to the upper end of main filling ta
