Definitions
- the invention relates to the field of filling spouts, in particular those intended for bottle filling machines.
- I t is already known to produce filling spouts which condition a jet of conical or "umbrella" product. Used for filling bottles, they make it possible in particular to ensure that the product is sprayed, very quickly as soon as it leaves the spout, against the internal lateral wall of the bottle. Thus, the product is introduced into the bottle by flowing along the internal wall, and not by being sprayed directly at the bottom of the bottle. In this way, the filling of the bottle is carried out with the least amount of foaming possible, which makes it possible to increase the filling rate and therefore to reduce the time necessary for filling a bottle.
- I t is also known to have, in such a type of spout, an axial cannula which allows to evacuate the air initially contained in the bottle without po r disturbing the coniq ue jet.
- the invention therefore aims to propose a new design for a filling spout which, while retaining the qualities specific to the spouts described above, also makes it possible to greatly limit or even eliminate the contact of the bottled product with the 'air.
- the invention provides a filling spout for dispensing a liquid in a container, of the type in which the spout includes a liquid distribution orifice that conditions an umbrella jet, and of the type in which the spout comprises an axial cannula provided with a gas evacuation duct which opens into the space delimited by the umbrella jet, characterized in that the cannula comprises a gas supply pipe which opens out inside the space delimited by the umbrella jet and which projects a flow of gas which flows essentially parallel to the umbrella jet of the liquid, on the internal side thereof.
- the gas supply pipe opens into the space delimited by the umbrella jet in the form of an annular opening
- the gas supply pipe has a substantially conical deflection surface;
- the discharge conduit opens axially at the center of the annular opening of the gas supply pipe, which opens axially at the center of the product distribution orifice which is substantially annular;
- the gas supply line is supplied with a neutral gas vis-à-vis the product to be distributed;
- the product jet has an axial rotation component
- the spout has an annular rotation chamber in which the product is injected with a tangential speed component, the rotation chamber being extended axially by an annular channel whose open end forms the product dispensing orifice ;
- the rotation chamber is connected to the annular channel by a funnel surface
- the invention also relates to a machine for filling containers, characterized in that it comprises at least one filling station provided with a filling spout incorporating any of the preceding characteristics.
- FIG. 1 is a schematic view in axial section of a filling spout according to the teachings of the invention, the spout being illustrated in operation during the filling of a bottle;
- FIG. 2 is a view on a reduced scale in cross section along line 2-2 of Figure 1.
- the filling spout 1 0 illustrated on the figures is more particularly intended for filling bottles 1 2 with narrow necks.
- I t could for example be used both for glass bottles and for plastic bottles such as polyethylene terephthalate (PET).
- PET polyethylene terephthalate
- such a spout will preferably be used for the manufacture of filling machines with multiple spouts, for example of the rotary carousel type,
- the spout 1 0 illustrated in the figures comprises essentially a hollow main body 1 4, substantially of revolution of axis A1, which is traversed axially right through by two coaxial tubes: an internal tube 1 6 and an external tube 1 8.
- the main body 1 4 therefore delimits an internal volume which is axially traversed by the tubes 1 6, 1 8.
- the main body 1 4, which is here represented in one piece, can also be produced in several pieces to facilitate the manufacturing.
- I t is capped by an upper cover 20 which seals the internal volume upwardly and which supports the tubes 1 6, 1 8.
- the cover 20 has an internal bore stage which passes axially through it.
- the upper stage 22 of the bore, which opens upwards towards the exterior of the main body, is cylindrical with axis A1, substantially of the same diameter as the external diameter of the internal tube 1 6.
- the lower stage r 24, which opens down into the internal volume, is cylindrical with axis A1, substantially the same diameter as the external diameter of the external tube 18.
- the intermediate stage 26, which extends axially between the upper 22 and lower 24 stages, is cylindrical with axis A1, substantially the same diameter as the internal diameter of the external tube 1 8.
- the upper end of the outer tube 1 8 is engaged axially from bottom to top in the lower stage 26 of the bore of the cover, until it comes to bear against an annular abutment surface which delimits the lower stage r 24 of the intermediate stage 26.
- the tube 1 8 is mounted with clamping and with the presence of an O-ring so as to ensure on the one hand the fixing of the external tube 1 8 on the cover 20, and on the other apart from the tightness of this assembly.
- the internal tube 1 6 is engaged, axially in the center of the external tube 1 8, so as to pass entirely through the cover 20.
- the internal tube 20 is held with clamping through the upper stage 22 of the bore of the cover, this which again ensures the fixing of the internal tube 1 6.
- the inside diameter of the outer tube 1 8 is greater than the outside diameter of the inner tube 1 6 so that when they are mounted coaxially on the cover 20, there remains between the two tubes 1 6, 1 8 an annular space which forms a pipe 28.
- the upper end of this pipe 28, which is formed by the intermediate stage 26 of the bore of the cover 20 is closed due to the sealed mounting of the internal tube 1 6 in the upper stage 22 of the bore.
- an inlet port 30 passes radially through the cover to open into the intermediate stage 24 of the bore and thus allow the communication of the pipe 28 with a source of fluid.
- the internal volume delimited by the main body 1 4 essentially comprises three parts: an upper rotation chamber 32, an acceleration cone 34, and an annular distribution channel 36.
- the rotation chamber 32 has here a shape simple ring arranged around the outer tube 1 8.
- a supply inlet 38 allows the product to be bottled to be introduced into the chamber 32 according to a orientation which is not purely radial but which, on the contrary, has a tangential component.
- the product is introduced into the chamber with a certain pressure, the product is entrained in a spiral circulation in the chamber, even in the case where this pressure comes only from the flow by gravity of the product.
- the annular distribution channel 36 through which the product to be bottled flows to the container 1 2, is formed around the lower part of the outer tube 1 8. In the illustrated embodiment, it is expected that this part of the spout 1 0 enters the interior of the neck of the container to be filled, so that the channel 36 has a smaller diameter than that of the rest of the main body 1 4.
- the channel 36 is delimited by a tubular cylindrical wall element.
- a connection surface 34 is provided which, for simplicity, has been chosen frustoconical.
- the internal shapes of the main body 1 4 of the spout 1 0 can be optimized, for example as illustrated in document US-A-5.1 25.441, without however departing from the teaching of the invention.
- the lower end of the outer tube 1 8 descends below the level of the lower end of the channel 36, thus delimiting an orifice 40 for the outlet of the product which is annular.
- the lower end of the outer tube 1 8 widens radially outward so that the outer surface of the outer tube thus forms a deflector 44 which tends to project the product radially outward so that 'it comes into contact with the inner wall of the container by forming an umbrella spray.
- the dimensions and the respective position of the end of the outer tube 1 8 and the end of the channel 36 are chosen so that the passage section of the outlet orifice 40 is relatively small, this in order to be able to retain r the liquid contained in the spout when the product supply is cut off.
- the maximum acceptable cross-section to prevent the product from dripping is determined in particular as a function of the intrinsic surface tension of the product.
- the lower end of the inner tube 1 6 projects axially below that of the outer tube 1 8 and the outer surface of the end of the inner tube 1 6 widens radially outward to form a surface. def defection 46.
- the lower end of the pipe 28 is therefore annular and widens radially outwards.
- the supply inlet 38 of the chamber 32 is connected to a storage tank for the product to be bottled, with the interposition of a controlled valve.
- the opening and closing of the valve can be controlled according to different parameters.
- I t can be a time command which determines a fixed filling time which will be applied to all the containers.
- the order may be of the weight type, the dispensing of product being interrupted when the container has reached a predetermined weight. It may also be a flow control in which the value of the flow rate delivered by the spout is integrated in order to have an estimate of the volume of product poured into the container. In the case of a volumetric machine, the quantity of product to be dispensed will be dosed in an intermediate volume placed between the storage tank and the filling spout.
- the inlet port 30 of the pipeline 28 for supplying gas will preferably be connected to a gas source which is not for the product under consideration. This neutral gas could for example be carbon dioxide (CO2) or nitrogen (N2).
- central duct 42 delimited inside the central tube 1 6 will be connected to a gas evacuation device or simply to the open air.
- the batch of product which is injected into the body of the spout is therefore rotated in the chamber 32, which, in combination with the annular shape of the outlet orifice 40 and with the shape of the deflection surface 44, ensures that the product is distributed by the spout in the form of an umbrella jet.
- the lower part of the spout being engaged in the container or being in the immediate vicinity of the latter, the product then comes into contact with the internal wall of the container and flows along it to fill the container. A flow is obtained which creates very little foam, even for high flow rates.
- the line 28 is supplied with a neutral gas so that the gas flow which flows through the lower end of the line 28 opens “below” the flow in product umbrella. Due to the flared shape of the defection surface 46, the gas flow flows substantially parallel to the product flow in the bottle.
- the product flow is somehow trapped between, on the external side, the container wall, and on the internal side, the neutral gas flow. In this way, the contact of the product with the ambient air is very limited, or even canceled.
- the discharge duct 42 allows the gases to escape from the container to the oven and as the level of product in the container increases. This escape is preferably done through the center of the container, upwards along the axis A1.
- the discharged gases can be either a part of the gas initially contained in the container before filling, or a part of the neutral gas supplied by the pipe 36.
- the nozzle according to the invention it is also possible to extend the inj ection of neutral gas beyond the time required for filling the product, this in order to perfect the sweeping of the head space of the container with a neutral gas to avoid trapping the air in the bottle, therefore in contact with the product, when the bottle is capped.
