Definitions

  • the present invention relates to a rotary filling machine for filling containers with liquids, according to the preamble of the main claim.
  • the machine in question is advantageously intended to be used in industrial bottling plants for filling containers, and preferably bottles, with liquids in particular of the alimentary type, such as beverages, wine, mineral water, etc.
  • the machine in question can be preferably used in bottling lines comprising typically a rinsing machine, a capping/capsuling machine or also, along the part of the line furthest downstream, a labelling machine and a packaging machine.
  • the machine in question is of the type which is provided, in a per se entirely conventional manner, with a rotating carousel (or turret) having, mounted along its periphery, a plurality of filling valves which are able to convey the liquid contained in a cylindrical tank inside the bottles.
  • filling machines are commonly classified as reduced-vacuum machines, isobaric machines, reduced-pressure machines, gravity machines, etc.
  • Reduced-vacuum filling machines have been designed mainly for filling containers with wines which are gas-free and are able to operate so that the pressure inside the container is reduced to the pressure (below atmospheric pressure) of the tank inside which the liquid to be introduced is stored and so that the air contained in the container is conveyed externally without coming into contact with the product.
  • the valves of these machines usually consist of a set of concentric tubes (usually two in number) one of which is inserted inside the other one; the outer tube is used for introducing the liquid into the bottle, while the air or gas contained inside the bottle rises up along the inner tube.
  • So-called isobaric filling machines have been designed mainly for filling containers with fizzy wines and operate under pressures much higher than atmospheric pressure. Filling of the containers is performed when the final pressure in the container is the same as the pressure inside a tank which is suitably mounted above the valves.
  • Reduced-pressure filling machines perform bottling in conditions where there is a slight pressure such that the fluid retains a small amount of gas, but without being subject to the technical requirements and regulations governing isobaric machines. This latter type of machine is particularly suitable for bottling smooth products and liquids which are slightly fizzy.
  • Volumetric or gravity filling machines envisage that filling is performed by means of free falling and constant metering; in this case, the product, drawn from a container, is conveyed to a series of metering devices and dispensed by the latter into the containers.
  • the filling machines of the known type described above provide ample possibility for adjusting, by means of a simplified user interface, the operating times and pressures of the filling valves. Owing to the possibility of adjusting the times required by the valves to execute given filling steps, it is possible to optimize the operations in relation to the instantaneous speed of the filling machine and the type of product to be bottled.
  • a further characteristic of more modern filling machines is the possibility of performing daily complete flushing, and in particular flushing of any part of the machine which comes into contact with the alimentary products to be bottled.
  • the filling machines which exist at present on the market, in particular for the wine industry, envisage typically a preparation and setting stage for adapting the filling product and the quantity of product to be introduced into the container to the format of the container to be filled.
  • This adjustment is achieved by means of overly complex mechanisms which slow down circulation of the liquids, increasing the loss of head therein and basically proving to be too expensive from a cost point of view and operationally disadvantageous.
  • each format change requires the intervention of specialized operators in particular to modify the setting of the air return tubes.
  • the patent GB - A- 1,316,629 describes a filling machine with a plurality of filling valves, which machine performs the adjustment of the level of the liquid into the containers by means of probes mounted on each of the filling valves at the end of corresponding shafts. It is possible to provide a common adjustment of the position of the probes of all the filling valves by means of pinions engaged on the corresponding probes, and moved, by a common driven mechanism, down and up for regulating the level of the filling liquid into the containers.
  • the main object of the present invention is therefore that of overcoming the drawbacks of the art known hitherto by providing a rotary filling machine for filling containers with liquids, which allows a change in format of the containers to be performed simply and rapidly.
  • Another object of the present invention is to provide a rotary filling machine for filling containers with liquids, which allows adjustment of the level in the containers to be performed automatically and with a high degree of precision and reliability.
  • Another object of the present invention is to provide a rotary filling machine for filling containers with liquids, which allows changing of the specific settings for each user, relating to the parameters associated with the bottles, the product and the filling temperature.
  • Another object of the present invention is to provide a rotary filling machine for filling containers with liquids, which allows optimization of the flushing operations as regards speed and working times and quality of flushing performed.
  • Another object of the present invention is to provide a rotary filling machine for filling containers with liquids, which allows the operator to switch over easily via a control panel the operating cycle envisaged between reduced-vacuum filling, reduced-pressure filling and finally gravity filling.
  • Another object of the present invention is to provide a rotary filling machine for filling containers with liquids, which is extremely safe for operators and highly reliable in terms of operation.
  • 1 denotes in its entirety the rotary filling machine for filling containers with liquids, according to the present invention.
  • the abovementioned machine 1 may be arranged, in a per se entirely conventional manner, inside a bottling plant, for example downstream of a rinsing machine and upstream of a capping machine to which it is operationally connected by means of conveying means.
  • the filling machine 1 ( Figure 4 ) is provided with an external frame 23, protective walls 24, 25 on the perimeter of the machine 1 and an external cabin 1a containing the electric and electronic operating devices ( Figure 1 ).
  • the machine is also provided, in a manner known per se, with a rotating carousel or turret 4 arranged inside the frame 23 and having, mounted along its periphery, a plurality of filling valves 6.
  • the containers 3, in particular bottles, to be filled are inserted inside the frame 23 and loaded onto the guide or conveyor belt 2 so that they proceed in the direction and sense defined by the entry arrow F1 and exit arrow FU.
  • the containers 3 must preferably be filled with alimentary substances such as milk, wine, fruit juice, etc., and for this purpose are conveyed, one after another, along the guide belt 2 and then transported into the vicinity of an entry starwheel 31 of the carousel 4 which performs, by means of the filling valves 6, all the steps necessary for bottling.
  • alimentary substances such as milk, wine, fruit juice, etc.
  • Each valve 6 has a pair of coaxial pipes 7, 8, i.e. an outer pipe 7 for supplying the liquid from a storage tank 20 to the container 3 to be filled which rotates on the carousel 4 underneath the corresponding valve 6, and an inner compensation pipe 8 (or air return tube) for determining the level of liquid inside the container 3.
  • the bottom portion of the pipes (or tubes) 7 and 8 is shaped so as to be inserted along at least a section of the neck of the bottle 3.
  • the terminal section of the inner compensation pipe 8 is intended to regulate hydraulically the maximum level of the liquid inside the container 3 as will be clearly specified below.
  • the liquid conveying duct is defined by the interspace existing between the outer surface of the inner compensation pipe 8 and the inner surface of the outer liquid supply pipe 7.
  • the two pipes 7, 8 are movable slidably with respect to each other so as to open and close a closing member arranged between them and, in accordance with a preferred solution of the present invention, consisting of a headpiece 120 fixed to the bottom end of the compensation pipe 8 against which the mouth 121 situated at the bottom end of the liquid supply pipe 7 is able to come into contact. Therefore, opening of the closing member 120 will occur when the outer pipe 7 is displaced with respect to the inner pipe 8, leaving a fluid flow aperture open.
  • the conveying duct is defined by the interspace between two concentric pipes, i.e. outer pipe and inner pipe. Therefore, it will be possible to envisage providing a dedicated compensation and air return pipe situated concentrically inside the outer pipe between which there will still be defined the duct for supplying the liquid from the tank 20 to the container 3 with the closing member arranged in between in a manner similar to that described above.
  • the closing member in the conveying duct may also be formed in another way known per se, such as, for example, by a widened nose-shaped portion of the inner pipe of the conveying duct able to come into contact against the annular shoulder provided on the inner side of the outer pipe of the conveying duct.
  • An extension guide 11 extends vertically downwards from the bottom 104 of the tank 20, said guide being coaxial and external with respect to the two pipes 7 and 8 and having, fixed at the bottom end, a seal 13 which is able to receive against it the mouth of the container 3.
  • the filling machine 1 comprises first actuator means 100 acting on the compensation pipe 8 of each filling valve 6 by means of transmission means 101 so as to vary simultaneously in an adjustable manner the vertical position of all the compensation pipes 8 with respect to the seal 13.
  • the position of the compensation pipe 8 with respect to the seal 13 determines the portion of the said compensation pipe 8 which penetrates into the container 3 and therefore, as will be clarified below, the filling level 9 inside the said container 3.
  • the first actuator means 100 act on the outer pipe 7 of each filling valve 6 by means of transmission means 101, varying simultaneously in an adjustable manner the vertical position of both the pipes 7, 8 with respect to the seal 13.
  • the transmission of the vertical movement to the compensation pipe 8 by the outer pipe is achieved by means of mechanical connections between the two pipes 7 and 8 and advantageously consisting of a spring 15 fixed at its ends to the pipes 7, 8.
  • seal 13 must be understood as referring to that part which is fixed to the tank 20 (in the examples consisting of a bottom end part of the extension guide 11 fixed underneath the tank) and against which the mouth of the container is intended to come into contact directly.
  • the machine 1 envisages an operation for setting the level of the container 3; this adjustment is entered by the operator directly on the panel, or one of the settings previously recorded in a special logic control unit of the machine is retrieved.
  • the first actuator means for example consisting of an electromechanical system such as, for example, one or more electric motors, operate simultaneously all the filling valves 6, via transmission means 101 for example formed by a regulating ring 17 connected on the one hand to the first actuator means 100 and fixed on the hand to the outer liquid supply pipe 7 of each of the filling valves 6 by means of mechanical transmission arms 10.
  • transmission means 101 for example formed by a regulating ring 17 connected on the one hand to the first actuator means 100 and fixed on the hand to the outer liquid supply pipe 7 of each of the filling valves 6 by means of mechanical transmission arms 10.
  • the first actuator means consist of a motor 110 mounted on a motor support bracket 111 which is connected by means of an angular transmission to an internally threaded driven wheel 112 inside which an acme-thread screw 113 fixed at its bottom end to the regulating ring 17 engages.
  • activation of the motor 110 causes, via the transmission means 101, raising and lowering of the two pipes 7 and 8, adjusting the filling level 9 of the containers 3.
  • the first actuator means 100 may be formed by other driving systems such as linear actuators or other equivalent means for raising the ring 17.
  • the transmission means 101 may similarly in turn be formed with kinematic mechanisms of various types which are well known to the person skilled in the art.
  • the outer pipe 7 may have advantageously at the top end a widened part 102 for fastening to the corresponding transmission 10 (for example between two parallel plates).
  • the transmission 10 may however, differently, also be connected to other parts of the valve 6 in turn connected to the pipes 7 and 8.
  • the regulating ring 17 acts as a locating element for determining the level 9 reached inside the containers 3, being able to determine simultaneously the position of all the pipes 8 for compensating the level 9.
  • the coaxial pipes 7, 8 pass through the lid 104 and the bottom 105 of the tank 20, there being provided an upper seal 106 and a bottom seal 107 through which the pipes 7, 8 slide following operation of the first actuator means 100.
  • the abovementioned transmission 10 imparts a vertical movement to the entire filling valve 6 (denoted by a dot-dash line) so that the latter slides inside the tank 20 and the extension guide 11.
  • This regulating system is extremely rapid as regards setting thereof, has a fast movement and reliable dynamic seals and reaches the given height in a precise manner.
  • This movement system also has the convenient advantage that it does not require any further movement during operation with the same batch of containers 3, reducing substantially wear and consumption.
  • the container 3 is rested on the raising cylinder 5 which rises and brings the neck 14 of the container 3 (in the case in question, the neck 14 of a bottle) into sealing contact with the seal 13 situated underneath the filling valve 6, with a pressure suitably designed to ensure optimum operation of the machine according to the invention ( Figures 2 - 4 ) and at the same time reduce as far as possible the stresses acting on the neck 14; at the same time, a first valve 18 of the filling valve 6 is opened and is connected to a vacuum circuit by means of a first suitably separated duct 27 and causes suction of all the air from the bottle 3
  • a vacuum is thus created inside the bottle 3 so as to evacuate any polluting gas which may be present.
  • opening of the filling valve 6 is performed by means of operation of second actuator means consisting of a pneumatic cylinder 28 which is mounted above the valve 6 and which is lowered by acting on the top end of the compensation pipe 8 which is thus forced to slide inside the outer pipe 7, causing opening of the closing member 120.
  • Each regulating valve 6 is provided at the top, above the tank 20, with associated second actuator means 28 which are advantageously supported and fixed to the outer pipe 7 (together with which they are therefore able to move) and are able act on the top end of the inner compensation pipe 8 so as to vary the relative position thereof with respect to the outer pipe 7, causing opening of the closing member.
  • Lowering of the pneumatic cylinder 28 causes at the same time also opening of a third valve 12B, which connects the inside of the container 3 to a separate reduced-vacuum circuit 16 by means of the compensation pipe 8, allowing filling of the container 3 to the desired level 9 when the filling valve 6 closes again as a result of the action of the spring 15 which pushes against the action of the pneumatic cylinder 28, overcoming the pressure thereof, when the latter is deactivated.
  • the pressure of the separate reduced-vacuum circuit 16 is suitably stabilized in relation to the pressure of the tank 20 and the inside of the container 3, in order to optimize the filing speed and fluidity.
  • This pressure of the separate circuit 16 is typically, although not exclusively, defined so that it is the same as the internal pressure of the tank 20.
  • the suitable introduction of the abovementioned completely separate circuit 16 allows the total evacuation of the gas contained inside the container 3, so as to prevent in an entirely reliable manner the gas present in the container 3 from contaminating the gas present inside the tank 20.
  • the third valve 12B closes, while a fourth valve 12A opens and connects the compensation pipe 8 inside the tank 20.
  • Release of the pneumatic cylinder 28 and suitable opening of the second valve 19 connects the pressurised gas circuit 29 to the neck 14 of the container 3 and to the pipes of the filling valve 6 so that the pressurised gas pushes the excess liquid through the central hole of the compensation pipe 8.
  • the excess liquid instead of being introduced again into the tank 20, may be conveyed to a separate recirculation circuit 21 in order to prevent any possible contamination inside the tank 20 of the filling machine 1.
  • a separate recirculation circuit 21 in order to prevent any possible contamination inside the tank 20 of the filling machine 1.
  • the valves 12A, 12b are combined as a single valve, which envisages the return of self-levelling gas and liquid inside a single separate return duct 16 or alternatively the return completely into the tank 20.
  • valves 12A, 12B and 19 are closed so as to optimize the consumption of inert gas and without any further movement of any mechanical part.
  • opening of the second valve 19 occurs so as create a layer of inert gas inside the neck 14 of the bottle (container 3) and all around, since opening of the second valve 19 remains as such also during removal of the container 3 from the filling valve 6.
  • each filling valve 6, of the first and second valves 18 and 19 on the bottom of the extension guide 11 it is possible to optimize the time needed for execution of the filling cycle operations, speeding up the vacuum and gas insertion stages, since it is required to fill a smaller volume consisting of only the container 3 (bottle) and the suitably sized through-holes in the seal 13.
  • valves 12A, 12B, 18, 19 are electro-valves which are controlled by the logic control unit so that the respective opening times are determined accurately in order to optimize the filling cycle, it being possible to adjust them independently for each filling valve 6, so as to optimize the cycle for each filling valve 6, counteracting the effects of the mechanical machining tolerances.
  • the logic control unit is able to memorize the heightwise positions of the pipes 7, 8 or the filling valves 6 to which different container formats correspond and reproduce them with operation of the first actuator means simply via a control panel, so as to allow during a change in format of the bottles 3 rapid adjustment of the levels 9 set for all the filling valves 6.
  • Each filling valve 6 is operated so as to move vertically in a controlled manner simultaneously by the first actuator means 100 for adjusting the level 9 in the container 3 and includes the coaxial pipes 7, 8, the second actuator means 28, the closing member 120 and at least one valve 12A, 12b arranged so as to intercept the inner compensation pipe 8.
  • the concentric pipes 7, 8 can be operated by the first actuator means 100 so as to move upwards until they are completely retracted inside the extension guide 11 and preferably until they pass beyond the seal 13 so as to form, together with a closing lid 32 preferably pivotably mounted on the bottom portion of the extension guide 11, a closed receptacle 160 suitable for allowing recirculation of a flushing product both inside and outside the surface of the filling valve 6.
  • the lid 32 is operated automatically or manually so as to move between a closed position underneath the extension guide 11 (and in particular underneath the centring cone 150 as shown in Figure 6 ) and an open position for normal operation of the machine, where it is separated from the bottom of the guide 11.
  • the filling machine Owing to automation of the filling machine 1, not only can specific time schedules be determined for each format or group of containers 3, for each working temperature and for each substance treated, but it is also possible to personalize the individual operations of the pneumatic electro-valves 12A, 12B, 18, 19 of each filling valve 6 for their adjustment heightwise or depending on the liquid level to be obtained inside the bottle 3. Owing to this operational versatility, the machine may be used to operate with different operating cycles, including reduced-vacuum filling, reduced-pressure filling and also reduced-gravity filling.
  • the actuators of the valves 12A, 12B, 18, 19 and the pneumatic cylinder 28 may be made of materials which are entirely compatible with alimentary products, can be perfectly flushed and be equipped with a suitable control chamber which allows verification of any malfunctions, without contaminating the product used for filling the containers.
  • the abovementioned trays 33 are operated and positioned only at the time required, in particular when the flow of the containers 3 being supplied is interrupted, by means of suitable actuators 35, so that the individual filling valves 6 open and allow the product to flow out when they pass above the trays 33.
