Abstract
Description
- The present invention relates to a rotary filler machine comprising the characteristics expressed in the preamble to claim 1.
- The present invention is in particular destined to be employed in sectors in which the product to be inserted in the appropriate containers has such characteristics as to be subject to separation of the substances that compose it, with the heavier ones settling towards the bottom.
- In particular, products of this kind are substantially all those products that are solid at ambient temperature, and that are packaged at higher than ambient temperature, such that they are in the liquid state.
- Products of this kind are for instance stick deodorants, degreasing hand cleaner paste and stick glue.
- Although hereafter explicit reference is mostly made to this type of product, the present invention can nonetheless be similarly applied also to fill containers with any other liquid product, whether or not it has the problem of the separation of the substances composing it (for instance, fruit juices).
- The present invention is advantageously applicable in particular to weight-based rotary filler machines, i.e. machines in which the quantity of product inserted in each container is determined according to the weight of the product.
- Today's technology provides for the use of rotary or linear filler machines.
- Rotary machines are constituted by a fixed support structure whereon is pivotally engaged a rotary structure that supports a first carrousel and a second superposed carrousel.
- The first carrousel peripherally bears a plurality of housing plates for the containers to be filled, whilst the second carrousels bears a plurality of filling devices, each of which is positioned above one of the plates to fill the related container.
- The filling devices are fed from an upper tank integral with the rotating structure, which contains the product that may be kept in the liquid state by means of appropriate heating elements.
- Rotary machines allow for the continuous filling of the containers, but they have the drawback that they are unable to keep the product always with a homogeneous composition, because the product itself tends to settle inside the tank, as well as in the conduits that join the tank to the filling devices.
- Linear machines, on the other hand, have one or more filling devices positioned in correspondence with a work station identified along a rectilinear path of advance of the containers
- Thanks to the static nature of the work station, the product is fed to the filling devices always correctly mixed, directly from the machines that prepared it.
- This type of machines, however, also has a considerable drawback, since its productivity is very limited.
- The filling operation cannot be conducted continuously, but requires three successive steps: a step of loading the containers underneath the filling devices, a step of filling the containers with the products, and a step of removing the full containers.
- In this situation the technical task constituting the basis for the present invention is to provide a rotary filler machine that overcomes the aforementioned drawbacks.
- In particular, a technical task of the present invention is to obtain a filler machine that allows to have a continuous filling of the containers.
- Another technical task of the present invention is to provide a rotary filler machine that assures the ability of maintaining the product always with a homogeneous composition.
- The specified technical task and the indicated aims are substantially achieved by a rotary filler machine, as described in the accompanying drawings.
- Further features and advantages of the invention shall become more readily apparent from the detailed description of a preferred, but not exclusive, embodiment of a rotary filler machine, illustrated in the accompanying drawings, in which:
- Figure 1 shows a schematic top view of an apparatus for filling containers, comprising the filler machine of the present invention;
- Figure 2 shows a sectioned front elevation of a filler machine according to the present invention, with some parts removed the better to highlight others;
- Figure 3 shows the machine of Figure 2 in raised position;

- Figure 8 shows a top view of the device of Figure 7 according to the trace VII-VII with some parts removed the better to highlight others.
- With reference to the aforementioned figures, the
reference number 1 globally indicates a rotary filler machine, according to the present invention in a complex embodiment thereof - Figure 1 shows a plan view of a complete apparatus 2 (known except for the filling
machine 1 of the present invention), in which alinear feeding device 3 carries the containers to be filled to afirst transfer star 4 that in turn feeds them to afiller machine 1 which fills them with the product. - A
second transfer star 5 then draws them from thefiller machine 1 and delivers them to a capper machine that closes them. - In known fashion, depending on whether the filling and the subsequent capping were completed correctly, a
third transfer star 7 deposits the containers on anoutlet device 8a or on ascrapping device 8b. - The
rotary filler machine 1 is constituted by afixed support structure 9 which can be associated to the base of theapparatus 2 described above, and hence fixed relative to the ground (Figure 2). - A
rotary structure 10 is pivotally associated to thefixed structure 9 according to a vertical axis, and bears afirst carrousel 11 peripherally provided with a plurality ofhousing plates 12 for a container to be filled, arranged along a circumference of lay centred on the same axis of rotation, and asecond carrousel 13 peripherally provided with a plurality offilling devices 14, each positioned above one of theplates 12 to fill the container positioned on theplate 12 itself with a product in the liquid state. - In known ways, the machine is further provided with elements (such as pincers) for retaining the containers to be filled positioned on the plates 12 (not shown herein).
- Each
filling element 14 has aninternal conduit 15 having anend 16 for the entrance of the product and anend 17 for the exit of the product (Figure 7). Bothends filling device 14. - A
dispenser 18 is then connected in off-take fashion to theinternal conduit 15 to tap some liquid product from theconduit 15 and dispense it to the container. - Between the
filling devices 14 and the feeding means, thefiller machine 1 is further provided with at least amanifold 19 that has ajunction portion 20 integral with thefixed structure 9, and adistribution portion 21 pivotally engaged to thejunction portion 20 and integral with the rotating structure 10 (Figure 4). - In the
junction portion 20 of themanifold 19 are obtained at least afirst inlet conduit 22 and afirst outlet conduit 23 able to be connected to the means for feeding a first product in the liquid state (Figure 5). - On the
distribution portion 21 are instead mounted a plurality offirst outlet mouths 24 and a plurality of first inlet mouths 25 (Figures 4 and 6). - The
first outlet mouths 24 are in fluid communication with thefirst inlet conduit 22, whilst thefirst inlet mouths 25 are in fluid communication with the first outlet conduit 23. - Also provided are first pairs of
hydraulic connections 26, each composed by afirst delivery pipe 27 connected from one of thefirst outlet mouths 24 to theinlet end 16 of afilling device 14, and by afirst return pipe 28 connected from theoutlet end 17 of thesame filling device 14 to one of thefirst inlet mouths 25. - Said
hydraulic connections 26 allow the continuous flow of the first product between the feeding means and thefilling device 14 through themanifold 19. - In the illustrated embodiment, the
junction portion 20 of themanifold 19 comprises a widenedupper head 29 in which are mounted thefirst conduits cylindrical body 30 positioned under theupper head 29 with its axis coinciding with the axis of rotation of therotating structure 10. The rotating portion is instead constituted by atubular body 31 counter-shaped relative to thecylindrical body 30 and mounted in hydraulically sealed fashion externally thereto (Figure 4). - Between the
cylindrical body 30 and thetubular body 31 are also obtained at least a first and a secondannular chambers cylindrical body 30, and vertically distanced from each other. A first and asecond channels first inlet conduit 22 to thefirst chamber 32 and the first outlet conduit 23 to thesecond chamber 33. - The
first outlet mouths 24 are obtained radially in thetubular body 31 in correspondence with thefirst chamber 32, and, similarly, thefirst inlet mouths 25 are obtained radially in thetubular body 31 in correspondence with thesecond chamber 33. - Heretofore, a basic embodiment has been described in which the machine fills the containers with a single product.
- In the case of a machine provided with sixteen
plates 12 and with sixteenfilling devices 14, as in the accompanying figures, therefore, sixteenfirst inlet mouths 25 and asmany outlet mouths 24 would be present. - The accompanying figures instead show a more complete and versatile version of the
filling machine 1 of the present invention. - In this version, the
manifold 19 is substantially split in two, and further comprises at least asecond inlet conduit 36 and a second outlet conduit 37 integral with the junction portion 20 (Figure 5), also able to be connected to the feeding means, and a plurality ofsecond outlet mouths 38 and ofsecond inlet mouths 39, similar to thefirst inlet mouths 25. - The
second outlet mouths 38 are mounted on the rotatingdistribution portion 21 and are in fluid communication with thesecond inlet conduit 36, whilst thesecond inlet mouths 39 are mounted on the rotatingportion 21 and are in fluid communication with thesecond outlet conduit 37. - In particular, in the illustrated embodiment, between the
cylindrical body 30 and thetubular body 31 are further obtained at least a third and a fourthannular chambers cylindrical body 30 and vertically distanced from each other as well as from the first and thesecond chamber - The
second outlet mouths 38 and thesecond inlet mouths 39 are obtained radially in thetubular body 31 respectively in correspondence with the third and with thefourth chamber - Additionally, a third and a
fourth channel second inlet conduit 36 to thethird chamber 40 and the second outlet conduit 37 to thefourth chamber 41. - In this case, too, second pairs of
hydraulic connections 44 are provided, each composed by asecond delivery tube 45 connected from one of thesecond outlet mouths 38 to theinlet end 16 of afilling device 14 and by asecond return tube 46 connected from theoutlet end 17 of thesame filling device 14 to one of thesecond inlet mouths 39. - Said
second connections 44 allow the continuous flow of a second product between the feeding means and thefilling device 14 through themanifold 19, always keeping it separate from the first product. - In this case, part of the
filling devices 14 is connected to thefirst mouths second mouths - In the preferred embodiment, the
filling devices 14 are present in an even number and are uniformly distributed along their own circumference of lay. Advantageously, they are also connected alternatively to each plurality ofinlet mouths outlet mouths filling devices 14 can dispense the first product and half the second product. - According to manners that are wholly similar to those described heretofore, filler machines with the capability of dispensing a plurality of different products can also be provided. In this cases the
connector 19 will have, for each product, an additional pair of inlet and outlet conduits, as well as additional pluralities of inlet and outlet mouths connected from appropriate hydraulic connections to fillingdevices 14. - Advantageously, the number of plates 12 (and of filling devices 14) will be a whole multiple of the number of products to be dispensed, whilst the
plates 12 relating to each product will be uniformly distributed along their circumference of lay, and mutually distanced by a number ofplates 12 corresponding to the number of other products to be dispensed. - In regard to the structural conformation of the filling
devices 14, eachdispenser 18 comprises anozzle 47, oriented towards therelated plate 12, and ashutter 48, able to move between a first raised position (not shown herein) for opening thenozzle 47 and a second lowered position for closing the nozzle 47 (Figure 2). The operation of theshutter 48, which in the accompanying drawings is positioned inside theinternal conduit 15, is assured by apneumatic actuator 49 positioned externally to theconduit 15 and connected to theshutter 48 itself by means of a rigid connectingrod 50, provided withcentring appendages 50a. - The area of entry of the
rigid rod 50 into theconduit 15 is constructed with aflexible membrane 51 having its edge rigidly connected to a wall of the conduit and its central portion rigidly connected to therod 50 to guarantee the hydraulic seal, preventing rubbing between the various parts. - In the illustrated embodiment, the filling
machine 1 is of the weight-based type and it comprises aloading cell 52 associated to eachplate 12 to measure the weight of the product poured into the container. The weight reading is then transmitted to a remote electronic control unit (not shown) operatively connected to the filling devices 14 (in particular to related actuators 48) and is used to control the dispensing of the product according to pre-set values. - The electronic control unit is also programmed to adapt the dispensing of the product by each filling
device 14 according to the previous dispensing operation performed by thesame dispensing device 14, in order to have an ideal filling, consistent over time, of individual containers. - The electronic control unit can also be set by the operators through
appropriate control panels 53. - Advantageously, the
individual plates 12 of the filler machine can easily be removed by unscrewing an appropriate screw (not shown herein). - It is therefore sufficient to provide the
filler machine 1 with a series ofinterchangeable plates 12 of different sizes, to allow to adapt the machine to different formats of the containers to be filled, simply by replacing theplates 12. - In any case, in order to adapt in an even better manner the
filler machine 1 to containers of different formats, the rotatingstructure 10 is subdivided into alower part 54 bearing thefirst carrousel 11 and anupper part 55 bearing thesecond carrousel 13, which is connected in sliding fashion to thelower part 54 according to a vertical direction of sliding. Positioning means 56 allow to determine the position of theupper part 55 relative to thelower part 54. - In the illustrated embodiment, the positioning means 56 are constituted by a
nut 57, able to be rotated by an operator by means of a wrench, which through anangular transmission 58 actuates a first threadedbar 59 connected by means oftransmission belts 60 to threesupport element 61 constituted by threadedbars 62 screwed in cylinders 63 (the accompanying figures show only one). - The machine represented in the accompanying figures is then destined to be used with products that need to be maintained in the liquid state by means of continuous heating, and for this purpose it is provided with heating means 64 connected to the control unit.
- In particular, both the
filling devices 14 and the manifold 19 are provided with electrical resistors (not shown herein), whereof thehousing seats 65 are shown, whilst thehydraulic connections 26 44 are constituted by commercial electrically heated pipes. - Additionally, probes (not shown herein) are provided, also housed in some of the
housing seats 65 and connected to the control unit. - A resistor and a probe can also be inserted in the
shutter 48. - All electrical and electronic connections between the fixed
structure 9 and the rotatingstructure 10 are obtained by means of known rotating connections inside a fixedconnection box 16 positioned under the rotatingstructure 10. - In regard to the operating modes of the subject machine, they can be adapted according to the user's needs.
- In particular, the machine can be used, for instance, to fill alternatively at successive times containers with different products, or to fill simultaneously containers with different products, or to fill containers with a single product adapting productivity as required.
- In the simplest operating mode, the machine operates exploiting only half the
plates 12 and the fillingdevices 14 to fill containers with a first product. - Once this production run is complete, the machine can immediately be converted to fill products with a second product with no need to empty it and clean it.
- It is sufficient, in fact, to exploit the second half of the
plates 12 and of the fillingdevices 14. - At the user's discretion, the two products (or more than two in the case of more complex machine) can also be dispensed simultaneously filling half of the containers with one and half with the other. This in particular can be found useful in the case of identical containers that can be filled with products having, for instance, different colours.
- In any case, the filling
devices 14 can also be used to fill simultaneously containers with the same product in order to increase the production of the machine. - In all cases of operation, the product is fed to the inlet conduit, always correctly mixed, directly by the apparatuses that prepared.
- Through the
first outlet mouths 24, it reaches the fillingdevices 14, where a part thereof is tapped when necessary, to return to the outlet mouths, and thence to the outlet conduit and then to the supply means. - With reference to Figure 1, the dispensing of the product into the individual containers takes place along the path travelled by the containers from the point of their drawing from the first transfer star to the point in which they are released to the second transfer star. Once the containers are loaded on the
first carrousel 11, theshutter 48 is opened and the product, which circulates under pressure, egresses. Thanks to the shaping of theoutlet nozzle 47, product splashes due to excessively fast egresses, are prevented. - When, through the
loading cell 52, the control unit sees that the proper quantity of product has been poured into a container, it activates thepneumatic actuator 49 to close theshutter 48. - Due to the delay of the closure relative to the time when the
loading cell 52 measures a determined weight, the command to close theshutter 48 is given when the weight reached is close, but lower than, to the required one, so that the product dispensed during the delay interval correctly completes the filling operation. - Since the quantity of product dispensed during the delay interval can vary over time, for instance because of slight differences in the composition of the product or temperature variations, at each filling the control unit checks the product actually dispensed at the end and, if necessary, changes the closure time for the subsequent cycles.
- The present invention achieves important advantages.
- In the first place, the filler machine of the present invention allows continuously to fill the containers.
- In the second place, said machine assures the capability of maintaining the product always with a homogeneous composition, thanks to the continuous circulation thereof in the conduits, without any stagnation areas. Additionally, this also holds true in the case of product that need to be continuously heated to remain liquid.
- Moreover, the machine of the present invention can be used to dispense any number of products, simultaneously or in succession.
- When the machine is used for a single product, the arrangement with two or more separate hydraulic systems allows to keep the manifold diameter, and consequently the related moment of inertia, to a limited size.
- It should be noted that the present invention is relatively easy to construct and that the cost connected with its embodiment is not very high.
- The invention thus conceived can be subject to numerous modifications and variations, without thereby departing from the scope of the inventive concept that characterises it.
- All components can be replaced by other technically equivalent elements and in practice all materials used, as well as the shapes and dimensions of the various components, can be any depending on requirements.
