Definitions
- the present invention relates to a machine for filling containers provided with a plurality of filling valves.
- each filling valve comprises a pneumatic valve, connected to a shutter to actuate it from an open position to a closed position of the valve and vice versa, and an electrical valve connected to the pneumatic valve to operate it.
- Said filling valve are used to introduce into the bottles a treatment fluid, e.g. a filling liquid, or nitrogen or carbon dioxide.
- a treatment fluid e.g. a filling liquid, or nitrogen or carbon dioxide.
- the filling machine comprises an electric manifold and a bank of electrical valves connected to the electric manifold.
- the electric valves are connected by means of electrical wires to the pneumatic valves, each of which is inserted within a valve body of a corresponding filling valve. Note that the pneumatic valves, having to be inserted into the corresponding filling valves to actuate the shutters, operate at high temperatures, in the order of 100 0 C.
- the electrical valves because of heat and humidity problems, are positioned in banks separate from the pneumatic valves and connected thereto with tubes and cables.
- the electrical valves normally have maximum operating temperatures of about 55°C; moreover, the electrical valves are easily subject to oxidation phenomena, which are definitely undesirable in a filling machine, due to hygiene-related problems.
- the electrical valves are positioned externally to the filling valves, to prevent them from being damaged by the humidity and high temperatures present within the filling valves.
- said solutions present some drawbacks. In the first place, said solutions require the use of a large number of electrical connection cables and of pneumatic tubes around the filling machine. The presence of a tangle of cables and tubes causes the presence of particularly dirty areas, hard to clean, and it makes maintenance operations on the machine difficult.
- An object of the present invention is to eliminate the aforesaid drawbacks and make available a filling machine with filling valves commanded by pneumatic valves, which in turn are actuated by electrical valves, that is particularly simple and economical to install and to operate.
- each filling valve comprises, in combination: - a valve body containing in its interior the pneumatic valve and the corresponding electrical valve; - a protective layer inserted in a gap between the valve body and the block constituted by said pneumatic valve and electrical valve.
- - figure 1 shows a filling valve of a filling machine according to the present invention
- - figure 2 shows a function diagram of the filling machine of the present invention.
- the reference number 1 designates a filling valve in a filling machine according to the present invention.
- the filling machine in its entirety is to illustrated, because it is known; it comprises a plurality of filling valves 1, e.g. positioned in a carrousel.
- the filling valves 1 serve the purpose of introducing into containers fluids of various kinds, depending on the needs, e.g. a filling fluid, or nitrogen or carbon dioxide.
- Each filling valve 1 comprises
- a pneumatic valve 3 connected to the shutter 2 to actuate it from a closed position to an open position and vice versa.
- the shutter 2 is movable between the open position, the closed position and an intermediate position between the open and the closed position, to enable a throttling of the flow of fluid delivered by the valve 1, according to a technique.
- the shutter 2 can be movable with continuity between the open position and the closed position.
- the filling machine 1 comprises, for each filling valve 1, an electrical valve 4 operatively connected to the corresponding pneumatic valve 3 to operate it.
- the electrical valve 4 and the pneumatic valve 3 are preferably connected to each other in such a way as to be integral with each other.
- the electrical valve 4 is able to operate at high temperatures, in particular higher than 100 0 C. In this light, the electrical valve is preferably of the type for high temperatures.
- the reference number 5 designates an intake conduit, to connect the pneumatic valve 3 to a source 6 of compressed air; the reference number 7 designates a delivery conduit, through which the pneumatic valve 3 actuates a piston 8, to move the shutter 2 from the open position to the closed position.
- the filling valve 1 comprises a spring 9 positioned in such a way as to exert a thrust on the piston 8 towards the open position of the shutter 2.
- the reference number 10 designates a conduit for the discharge of the air, for evacuating air from the pneumatic valve 3.
- valve body 11 the pneumatic valve 3 and the piston 8 (and the spring 9, when it is present) are contained in a valve body 11.
- each filling valve 1 originally, the electrical valve 4 is contained within the valve body 11 , together with the pneumatic valve 3.
- each filling valve 1 comprises, originally, a protective layer
- the pneumatic valve 3 and the electrical valve 4 constitute a single block, so the protective layer 12 is applied onto an external surface of the block constituted by the pneumatic valve 3 and by the electrical valve 4.
- Said protective layer 12 is preferably constituted by a polymer introduced into said gap, e.g. resin or polyurethane foam or silicone.
- said polymer is introduced into the gap preferably by means of an injection step.
- the protective layer 12 constitutes a hermetically sealing lid for the pneumatic valve 3 and the electrical valve 4, enabling, advantageously, a protection of the electrical valve 4 against possible oxidation, preventing infiltrations of humidity and of air.
- the machine 1 comprises a control unit 13, constituted for example by a PLC, interfaced with the electrical valves 4 to control them.
- the control unit 13 is preferably connected to all the electrical valves 4 of the corresponding filling valves 1, so that the electrical valves 4 are mutually interconnected.
- the machine 1 also comprises, for each electrical valve 4, a communication board 14, for the interfacing (or the communication) of the corresponding electrical valve 4 with the control unit 13.
- each communication board 14 originally, is contained within the valve body 11.
- each communication board 14 is contained within the protective layer 12; therefore, it is separated from the valve body 11 by the protective layer
- the present invention originally provides for the use of shielded cables 15.
- each electrical valve 4 is connected, through the respective communication board 14, with the control unit 13 by means of a single shielded cable.
- the present invention makes available, advantageously, a filling machine that is particularly simple and economical both with regard to installation and maintenance, because it comprises a minimal number of electrical cables for the operation of the electrical valves.
- the filling machine according to the present invention is particularly hygienic and reliable, because the electrical valves are protected against possible oxidation.
