Abstract

The apparatus comprises a vat (1) in the bottom of which a certain number filling devices (22) are arranged around the axis of the vat. Each device contains a filling pipe in communication with the vat (1) and which is traversed by a vent tube which is connected at its top with a connection pipe (54) outside the vat and debouching in the upper part of an air-liquid separator (56). The lower part of this separator is connected to a vat of liquid (64) by means of a pipe (62). At its top it is connected by pipes (58) to a pipe (60) in which the pressure is lowered. Since the vat is mounted on a rotary shaft (4), the pipe (60) is connected to the pipe (58) by a rotary joint on the cover of the vat. Likewise, a pressurized pipe from the vat is mounted, by means of the same rotary joint, inside the cover of the vat.

Dependent claims

A device for automatically filling bottles, comprising:

A. a vat for holding a supply of a liquid to be filled into said bottles;
B. a liquid reservoir;
C. a vacuum source;
and
D. at least one filling device, each said filling device comprising:
(1) a filling tube having an upper end in communication with the interior of said vat, said tube filling being vertically movable with respect to said vat;
(2) a vent tube axially traversing said filling tube and having a lower end below a lower end of said filling tube;
(3) a valve for opening and closing said filling tube in response to a position of a bottle to be filled;
(4) an air-liquid separator reservoir disposed below said vat and above said liquid reservoir, an upper end of said separator reservoir being communicated with an upper end of said vent tube and with said vacuum source;
and
(5) a pipe connecting a lower end of said separator reservoir to said liquid reservoir, wherein:
a lowered pressure created by said vacuum source in said air-liquid separator reservoir pulls liquid from said liquid reservoir into said pipe for a predetermined height.
