Abstract
A machine for the filling of containers, and in particular for the fillings of bottles, which combines advantages of a traditional isobaric machine with those of a machine operating under a slight depression, such as a good seal at a neck of a bottle and a minimum absorption of air by an introduced liquid. The machine allows performing steps of pre-evacuating air inside the bottle and insufflating an inert gas through the neck of the bottle.
Claims15
A machine for the filling of containers in particular for the filling of bottles comprising at least one container receiving a liquid drained from a nozzle of a filling section of said machine by opening a tap, said nozzle being arranged at one of the ends of a piping system comprising two concentric tubes respectively crossed in opposite directions by the flow of said liquid originating from at least one storage tank and of air aspirated from the outside portion of said container, which is moved in the direction of the falling liquid, by an actuating system comprising a table pushing against the bottom of said container and causing it to tightly adhere to a sealing ring of said tap, for the purpose of aspirating the air inside the container, said tubes being actuated by corresponding commanding devices for closing said tap, with said machine further providing a member for insufflating inert gas inside said container, wherein said actuating system is governed by a continuous rotating motion of a first cam having a contoured profile connected to the profile of at least one transmission member receiving a variable motion, depending on the various positions assumed by said first cam, said transmission member being connected to said table supporting said container in such a manner as to advance or retract said container from said filling section and said tap.
