Definitions
- the present invention relates to a machine for filling containers with liquid or powder products.
- the invention has application to advantage in the art field of carousel type machines used to fill containers with a variety of substances, including liquid food products such as milk or fruit juices, also mineral lubricating oils, detergents, etc.
- a filling machine of the type in question appears as a tank carried by a main carousel and holding a supply of the liquid substance; the carousel is rotatable about a vertical axis through a first transfer station by way of which it receives a succession of containers, each presenting a filler mouth.
- the tank is rigidly associated with the carousel and affords a plurality of filler valves at the bottom, each of which can be associated with the mouth of a respective container; thus, when the carousel is set in rotation, the tank turns on the vertical axis and its contents are released via the filler valves into the containers, whereupon the filled containers are directed by way of a second transfer station onto an outfeed conveyor.
- Filler valves of conventional type like the one shown in the documents US-6 073 667 and US 5 676 334 comprise a feed duct terminating at the bottom end in a dispensing outlet such as can be opened or closed by a valve element sliding axially within the duct.
- the valve element is attached to the end of a rod operated by suitable devices installed above the filler valve.
- the feed duct is vertically disposed, extending downward from a bottom wall of the tank so that the tank can be emptied entirely of its contents. Accordingly, each rod passes through the tank and connects with the relative operating device, which is located internally of the tank and above the free surface of the product contained therein; the operating devices, preferably, will be separated from the product by a suitable partition baffle.
- the presence of the rods in the space occupied by the product being dispensed from the tank can lead to contamination of the selfsame product, whilst the operation of cleaning the tank, which must be undertaken before changing over to a new product, can be rendered more difficult and less thorough.
- the structure of the rods is such as to create interstitial spaces in which the product will stagnate and collect.
- servicing of the rods is complicated by the fact that any repair or replacement operation necessitates their removal from the tank.
- the object of the present invention is to provide a machine for filling containers with liquid products or powder products, such as will be unaffected by the drawbacks mentioned above.
- One object of the invention is to make available a machine for filling containers with liquid or powder products, of which the filler nozzles can be serviced easily without having to dismantle any part of the tank.
- a further object of the invention is to provide a machine such as will ensure products are handled in conformity with pertinent hygiene standards.

Abstract
Description
- The present invention relates to a machine for filling containers with liquid or powder products.
- The invention has application to advantage in the art field of carousel type machines used to fill containers with a variety of substances, including liquid food products such as milk or fruit juices, also mineral lubricating oils, detergents, etc.
- A filling machine of the type in question, as disclosed in
US 6073667 , appears as a tank carried by a main carousel and holding a supply of the liquid substance; the carousel is rotatable about a vertical axis through a first transfer station by way of which it receives a succession of containers, each presenting a filler mouth. - The tank is rigidly associated with the carousel and affords a plurality of filler valves at the bottom, each of which can be associated with the mouth of a respective container; thus, when the carousel is set in rotation, the tank turns on the vertical axis and its contents are released via the filler valves into the containers, whereupon the filled containers are directed by way of a second transfer station onto an outfeed conveyor.
- Filler valves of conventional type like the one shown in the documents
US-6 073 667 andUS 5 676 334 , comprise a feed duct terminating at the bottom end in a dispensing outlet such as can be opened or closed by a valve element sliding axially within the duct. The valve element is attached to the end of a rod operated by suitable devices installed above the filler valve. The feed duct is vertically disposed, extending downward from a bottom wall of the tank so that the tank can be emptied entirely of its contents. Accordingly, each rod passes through the tank and connects with the relative operating device, which is located internally of the tank and above the free surface of the product contained therein; the operating devices, preferably, will be separated from the product by a suitable partition baffle. - The presence of the rods in the space occupied by the product being dispensed from the tank can lead to contamination of the selfsame product, whilst the operation of cleaning the tank, which must be undertaken before changing over to a new product, can be rendered more difficult and less thorough. In effect, the structure of the rods is such as to create interstitial spaces in which the product will stagnate and collect. Moreover, servicing of the rods is complicated by the fact that any repair or replacement operation necessitates their removal from the tank.
- These drawbacks have been overcome to an extent by adopting filler valves connected to rods and actuators located externally of the tank, with the relative valve elements operated via levers, although the structure of the machine is rendered notably more complex. A filler valve of the type in question is disclosed, for example, in
EP 1129949 . - Accordingly, the object of the present invention is to provide a machine for filling containers with liquid products or powder products, such as will be unaffected by the drawbacks mentioned above.
- One object of the invention, in particular, is to make available a machine for filling containers with liquid or powder products, of which the filler nozzles can be serviced easily without having to dismantle any part of the tank.
- A further object of the invention is to provide a machine such as will ensure products are handled in conformity with pertinent hygiene standards.
- The stated objects are realized in a machine according to the present invention for filling containers with liquid or powder products, of which the characterizing features are recited in one or more of the appended claims.
- The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which:
-
figure 1 shows a preferred embodiment of a machine according to the present invention for filling containers with liquid or powder products, viewed in elevation; -
figure 2 shows a detail of the machine illustrated infigure 1 , viewed partly in section; -
figure 3 is a section on the plane denoted III-III infigure 2 ; -
figure 4 shows the detail offigure 2 in an alternative embodiment. - With reference to
figure 1 , numeral 1 denotes a filling machine, in its entirety, designed to batch liquid or powder products intocontainers 2, each affording arespective filler mouth 3. - In the embodiment of
figure 1 , illustrated purely by way of example, the filling machine 1 comprises acarousel 4 rotatable about avertical axis 5. Thecarousel 4 carries supporting and weighing means 6 on which a plurality ofcontainers 2 can be placed, filled with a product P and weight-checked while caused to advance along a circular filling path extending about thevertical axis 5 of the carousel from an infeed station to an outfeed station, both conventional in embodiment and therefore not illustrated. -
Containers 2 are received in succession by thecarousel 4 at the infeed station, and transferred ultimately from the outfeed station to a take-up unit, not shown in the drawings. - The machine 1 comprises feed means supplying a product P, which in the embodiment illustrated are shown as a
tank 7 holding the selfsame product P. - The
tank 7 is mounted to thecarousel 4 and carries a plurality ofnozzles 8 distributed about theaxis 5 of rotation, from which thecontainers 2 positioned on the supporting and weighingmeans 6 are filled with the product. - Referring to
figure 2 , in particular, each of thefiller nozzles 8 comprises abarrel 10 preferably of cylindrical shape, delimiting afeed duct 9 aligned on anaxis 11 disposed parallel to thevertical axis 5 of thecarousel 4. - The
duct 9 terminates at bottom in a dispensingoutlet 12 directed toward arelative container 2 positioned for filling, and is equipped internally with avalve element 13 capable of movement between a position in which theoutlet 12 is closed and a position in which theoutlet 12 is open. - The
valve element 13 and the inside surface of theduct 9 adjacent to the dispensingoutlet 12 are shaped in such a way that the outflowing stream of the product P will assume selected characteristics of geometry, velocity and pressure. - Motion is induced in the
valve element 13 by operating means 14 mounted advantageously inside ahousing 15 incorporated into thefeed duct 9. Thehousing 15, which appears tapered and preferably of ogival geometry, with adomed portion 16 directed toward thetank 7, is aligned on thelongitudinal axis 11 of theduct 9 and presents a cross-section smaller than that of the duct, as discernible infigure 3 , with the result that a flow passage of predeterminedcross-sectional area 17 is offered to the product P. - The
housing 15 thus occupies a position distanced from aninner side wall 18 of theduct 9 and is joined to the wall by way of at least onearm 19, of which the function is to support thehousing 15. In the preferred solution illustrated, thenozzle 8 presents a pair ofarms 19 fashioned integrally with and extending radially in opposite directions from thehousing 15. - The contours of the
housing 15 are optimized in order to create fluidynamic characteristics such as will minimize turbulence in the flowing product P, whilst thecross-sectional area 17 is preferably constant along the length of the duct, or tapered toward the dispensingoutlet 12. - The
housing 15 presents abottom portion 20 with an opening 21, located at the end opposite from thedomed portion 16 and directed toward the dispensingoutlet 12. The opening 21 is occupied slidably by arod 22 extending partly into achamber 23 afforded by thehousing 15 and carrying thevalve element 13 at one end, externally of the housing. Axial motion induced in therod 22 causes thevalve element 13 to shift between the open and closed positions. - To prevent the product P from entering the
chamber 23, thehousing 15 is equipped withsealing means 24, provided for example by a wiper ring offered in sliding contact to therod 13 and fitted to thebottom portion 20, at theopening 21. - The movement of the
rod 22 is produced preferably by pneumatic or electromagnetic means. - As illustrated in
figures 2 and3 , the operating means 14 comprise apiston 25 rigidly associated with therod 22, accommodated slidably in thechamber 23 of thehousing 15 and engaging with aside wall 26 of the selfsame chamber by way ofseals 27. - The
chamber 23 is connected to at least onesource 28 of pressurized gas, so that thepiston 25 can be driven by admitting and exhausting the gas. - More exactly, the
chamber 23 is separated by thepiston 25 into a top cavity denoted 29 and a bottom cavity denoted 30, both of variable volume. - A
first duct 31 formed in thehousing 15 connects thetop cavity 29 with afirst valve 32 installed on thehousing 15, and asecond duct 33 connects thebottom cavity 30 with asecond valve 34. Eachvalve pressure source respective cavity - The entry of gas by way of the
first valve 32 into thetop cavity 29 causes thepiston 25 and thevalve element 13 to shift toward theoutlet 12, in other words toward the closed position. At the same time, the gas contained in thebottom cavity 30 is compressed to a degree by thepiston 25 and forced out via thesecond valve 34. - Conversely, the entry of gas by way of the
second valve 34 into thebottom cavity 30 causes thepiston 25 and thevalve element 13 to shift away from theoutlet 12, in other words toward the open position. At the same time, the gas contained in thetop cavity 29 is compressed to a degree by thepiston 25 and forced out via thefirst valve 32. - To assist the action of the gas in closing the
outlet 12 and/or keep the outlet closed when there is no gas supply to the machine 1, thenozzle 8 further comprises aspring 35, preferably a coil spring, seated between thepiston 25 and anend wall 36 of thetop chamber cavity 29 in such a way as to bias thevalve element 13 toward the dispensingoutlet 12. - In an alternative embodiment of the machine, not illustrated, the operating means might include only the
first duct 31 connecting with thetop cavity 29 of the chamber, and theoutlet 12 could be closed by the action of thespring 35 alone. - Where motion is induced electromagnetically (see
figure 4 ), theoperating means 14 will be composed, for example, of a fixed field winding 37 installed in thechamber 23 and powered by asuitable control circuit 38, and a movingpart 39 of ferromagnetic material rigidly associated with therod 22. The movingpart 38 is paired with the field winding 37 and functions as a solenoid plunger. - In operation, when the
field winding 37 is fed with a current of sufficient strength generated in a direction determined by thecontrol circuit 38, an electromagnet field is induced in theplunger 39 which, depending on the direction of the current through the field winding 37, will set up an electromotive force tending to direct theselfsame plunger 39 along theaxis 11 of theduct 9 toward the position that opens or closes theoutlet 12. This electromagnetically induced type of movement could be assisted likewise by the action of the aforementioned spring 35 (not shown infigure 4 ). - To facilitate access to the operating means 14 and simplify maintenance of the
nozzle 8, as illustrated in the example offigures 2 and3 , thecylindrical barrel 10 is embodied as a plurality of tubular sections assembled coaxially with and separable one from another. - A flared
first section 40 is connected to atubular coupling 41, for example a straight piece extending from anopening 42 presented by abottom wall 43 of thetank 7. Thefirst section 40 is butt-joined to thecoupling 41 together with an interposedannular seal 44 and secured thus by means of a "C"profile clamp collar 45, removable with ease using normal workshop tools. To guarantee a secure assembly, thefirst section 40 and thecoupling 41 are fashioned with respectiveannular projections 46 around the mating edges, which when joined one with another will fit into the groove of the "C"profile collar 45. - A second
tubular section 47 is butt-joined to thefirst section 40 and secured with afurther clamp collar 45 of the type described above. Thesecond section 47 carries thehousing 15, which is axially longer and embodied preferably in one piece with theselfsame section 47. - The dispensing
outlet 12 is located in the bottom end of a taperedthird section 48 joined to thesecond section 47, secured by means of arelative clamp collar 45 and encasing thebottom portion 20 of thehousing 15 together with therod 22. - Finally, the
bottom portion 20 of thehousing 15 is mounted removably, for example screw-coupled to a top portion 49 integral with thearms 19 and with the secondtubular section 47, so as to allow the removal of therod 22 and the operating means 14 from thechamber 23.
