Definitions

  • the present invention refers to a filling machine and to a method for sanitising said filling machine, according to the preamble of the relative main claims 1 and 12 respectively and known from EP 0 785 134 A2 .
  • the machine in question is advantageously intended to be used in industrial bottling plants to fill containers, and preferably bottles, with liquids in particular of the food and drink type such as wine, liquor, mineral water, oil, etc.
  • the machines in question can preferably be used within bottling lines comprising, typically, a rinsing machine, a capping/capsuling machine or also, in the part farthest downstream of the line, a labelling machine and a packaging machine.
  • Filling machines of food and drink products are usually provided, in a per sé totally conventional way, with a rotary carousel (or tower) carrying a plurality of valve assemblies mounted peripherally suitable for conveying the liquid contained in a cylindrical tank inside the containers to be filled. These, lifted by suitable support plates, are associated with the single valve assemblies to be filled up to the desired level during the operating stroke around the rotary carousel.
  • the filling machines are commonly classified as machines operating under slight depression, isobaric machines, machines operating under slight pressure, machines operating by gravity, etc.
  • so-called isobaric filling machines are mainly studied to fill containers with fizzy liquids, i.e. containing carbon dioxide, sparkling wines, champagne, etc. and work at pressures much higher than atmospheric pressure.
  • each valve assembly suitably fixed below the cylindrical tank, is equipped with a tubular pipe, which is intercepted by a shutter that adjusts the supply of alimentary liquid from the tank to the container below.
  • a compensation cannula is coaxially mounted through which the gas or the air present in the container is evacuated.
  • the supply of liquid into the container is controlled electronically through the actuation of actuators or else mechanically once the pressure in the container reaches the same pressure value as in the tank.
  • the air present therein goes out through the compensation cannula.
  • the lower part of such a cannula moreover, normally has the function of adjusting, for example hydraulically or through a probe, the maximum level of the alimentary liquid in the container.
  • filling machines need frequent sanitising operations, to be carried out even many times each day, for many reasons.
  • a first reason derives from the need to periodically carry out the cleaning of all of the parts of the machine, in particular the valve assemblies, which come into contact with the alimentary liquid to be bottled in order to keep the degree of concentration of microbes and bacteria in the bottled product within the limits permitted by the applicable national and international standards regarding contamination of foodstuffs.
  • the interruption for example, can be foreseen to carry out maintenance operations on the machine or else to suspend working activity.
  • a second reason is the need to change the product to be bottled and therefore clean the machine to avoid contamination between different liquids.
  • sanitising operations require that a sanitising fluid (mostly containing suitable liquid chemical products and/or steam) be run in all of the pipes where the liquid passes and where air or inert gas passes.
  • a sanitising fluid mostly containing suitable liquid chemical products and/or steam
  • This known sanitising method involves long manual operations to mount the rinsing containers below each valve assembly and does not allow the carrying out of sanitising treatments to be programmed automatically.
  • patent US 5,533,552 describes an isobaric filling machine equipped with a cylindrical casing (made from stainless steel), which extends from the bottom of the tank coaxially with respect to the rotation shaft of the rotary carousel and is arranged inside the valve assemblies.
  • a trolley is arranged supported by two guide shafts and carrying a mounted rinsing container.
  • Each trolley can be slidably moved through a pneumatic actuator, through an opening formed in the casing, between an operative position, that it takes up during the sanitising treatments and in which it is positioned with the rinsing container aligned below the centring cone of a corresponding valve assembly, and an inoperative position, that it takes up during the normal filling steps of the machine and in which it is positioned behind the casing closing the opening with a protective screen fixed to the front of the trolley.
  • the rinsing container is lifted from the trolley and brought to form a seal against the centring cone of the valve assembly, with an O-ring being foreseen arranged on the upper face of the rinsing container.
  • the sanitising liquid is injected into the tank and conveyed inside the valve assemblies until it reaches the rinsing containers below, from which it then goes back into the tank through the compensation cannula.
  • each rinsing container is lowered so that the trolley can then pull back behind the casing.
  • a first drawback is linked to the fact that such a filling machine allows only the inner surface of the centring cone to be sanitised, whereas its outer surface, which can also get dirty, is never washed by the sanitising liquid.
  • a further drawback derives from the fact that the gasket of the rinsing container against the centring cone is unable to withstand the high pressures at which the sanitising fluid is injected inside the valve assembly, which are necessary in order to obtain adequate sanitisation of the filling machine.
  • the sanitising liquid especially after many hours of operation when the gaskets are no longer new, tends to come out from the valve assemblies with losses that as well as fouling the machine also constitute a waste of sanitising liquid.
  • the main purpose of the present invention is therefore to overcome the drawbacks of the current prior art by providing a filling machine capable of carrying out sanitising operations in a totally automatic way.
  • Another purpose of the present invention is to provide a filling machine that is able to carry out sanitising operations that allow the outer surface of the centring cones of the valve assemblies to also be washed.
  • Another purpose of the present invention is to provide a filling machine that allows the sanitising operations to be carried out without losses of sanitising fluid from the valve assemblies.
  • Another purpose of the present invention is to provide a filling machine that is able to carry out the sanitisation of the valve assemblies through a fluid in countercurrent to improve the washing thereof.
  • Another purpose of the present invention is to provide a filling machine that allows the parts of the centring cone able to come into sealed relationship with the mouth of the container for filling to be easily replaced.
  • a rotary isobaric filling machine that is intended for bottling containers through fizzy fluids, generally used in the food and drink industry, like for example beverages with added carbon dioxide, sparkling wines, beer, mineral water, etc.
  • the filling machine 1 is conventionally inserted inside a bottling plant downstream of a rinsing machine and upstream of a capping machine.
  • the containers to be filled are transferred from one machine to the other through transportation lines, like for example conveyor belts, starwheels with recesses, Archimedean screws, etc.
  • the filling machine 1 comprises a support structure 2, resting on the ground, on which a rotary carousel 3 is rotatably mounted.
  • the latter is equipped with a vertical central rotation shaft 45 that supports a horizontal support disc 38.
  • the latter has columns 37 fixed to it that support a tank 4 containing the liquid to be bottled at a suitable pressure so as to prevent the gas dissolved in the liquid from being lost.
  • a plurality of valve assemblies 5 are mounted on the rotary carousel 3 peripherally under the tank 4 and are hydraulically connected to the latter to transfer the liquid to containers 7 to be filled below, generally consisting of glass or PET bottles. These are transported around the filling machine 1, in a per sé conventional way, by support means consisting, for example, of a plurality of plates 10 that rotate in synchrony with the valve assemblies 5 and are suitable for transferring the containers 7 from an entry recess 39 to an exit recess 40 (see figures 1 and 2 ).
  • each valve assembly 5 comprises a metal body or tap 44 in which a tubular pipe 6 is formed, which places the tank 4 in hydraulic communication with the container 7 to be filled below.
  • interception means 8 consisting for example of a shutter 12, which is mounted coaxially in the same tubular pipe 6 and can be moved between an open position, in which it is away from the inner wall of the tubular pipe 6 allowing the liquid to pass towards the container 7, and a closed position, in which it is in contact with the inner wall of the tubular pipe 6 blocking the passage of the liquid.
  • the shutter 12 is controlled to close through, for example, a pneumatic actuator, and is controlled to open through, for example, a return spring preloaded to push it into its open position when the container 7 reaches the same pressure as the tank 4.
  • the interception means 8, therefore, adjust the supply of liquid from the tank 4 to each container 7 that rotates in synchrony with the corresponding valve assembly 5.
  • the tubular pipe 6 ends with one or more dispensing openings 41 formed on a lower wall 16 of the tap 44, which is able to enter into sealed relationship with a centring cone 9 aligned with the same tubular pipe 6.
  • a centring cone 9 is connected to the valve assembly 5 through a horizontal support bracket 42 fixed to a pair of vertical shafts 43 slidably mounted on the same valve assembly 5 to allow the centring cone 9 to move between a lower position, in which it is away from the tap 44 (see figure 4 ), and an upper position, in which it is sealed on the tap 44 (see figures 2 and 5 ).
  • Each valve assembly 5 is also equipped with a compensation cannula 68 for the return of air, mounted concentrically to the tubular pipe 6 and intercepted by a mechanical valve, preferably also associated with a pneumatic valve, to control the pressure equilibrium between the container 7 and the tank 4.
  • a compensation cannula 68 for the return of air, mounted concentrically to the tubular pipe 6 and intercepted by a mechanical valve, preferably also associated with a pneumatic valve, to control the pressure equilibrium between the container 7 and the tank 4.
  • a compensation cannula 68 during the operation of the filling machine 1, is able to pass through the centring cone 9 to insert inside the container 7 below.
  • Each valve assembly 5 is conventionally equipped with foreseen control valves to adjust specific steps of the filling process of the containers 7, like for example, in the example case described of an isobaric machine: the pre-evacuation, pressurisation, self-levelling and degassing step.
  • each valve assembly 5 comprises an intercept valve of a vacuum circuit intended to take in all of the air from the container 7 during the pre-evacuation step, an intercept valve of an isobaric circuit intended to bring the container to the pressure of the tank 4 making the air of the tank 4 itself, or rather an inert gas, flow in during the pressurisation step of the container 7, an intercept valve of a self-levelling circuit intended to blow an inert gas in the container 7 during the self-levelling step.
  • Such intercept valves place the respective circuits in communication with the container 7 through a further poppet valve 71 mounted in common with the different circuits on the tap 44.
  • the poppet valve 71 connects such circuits to an auxiliary pipe 72 that is formed on the tap 44 and extends inside it until it passes through its lower wall 16.
  • degassing valves 84 to evacuate the air or the gas in overpressure in the container once it has been filled with the liquid to be bottled.
  • the filling machine 1 object of the present invention also comprises a plurality of rinsing containers 13 of a sanitising fluid, each of which can be operatively and mechanically associated with one of the valve assemblies 5 during the foreseen sanitising treatment.
  • first actuator means 76 are foreseen to move each rinsing container 13 between an inoperative position, in which the rinsing container 13 is moved into a position withdrawn outside of the working bulk of the valve assemblies 5, and an operative position, in which the rinsing container 13 is vertically aligned below a corresponding valve assembly 5.
  • the first actuator means 76 advantageously comprise first pneumatic cylinders 96 that determine the rotation of a crown gear 97, engaged with a plurality of pinions 46 arranged peripherally on the rotary carousel 3. As illustrated in detail in figure 4 , each pinion 46 is fixed around a vertical pin 47 rotatably mounted on the support disc 38 of the rotary carousel 3. A substantially horizontal deviation arm 48 is fixed at a first end 49 thereof to the pin 47 and at its second end 50 to one of the rinsing containers 13.
  • the pinions 46 in groups of pinions arranged in succession along contiguous arcs of circumference of the carousel.
  • the pinions of each group are rotatably engaged with each other by gear wheels arranged between the pinions and are set in rotation by a corresponding pneumatic cylinder 96, which acts with the end of its stem on a toothed sector engaged with the pinion of a group to simultaneously set all of the pinions of the same group in rotation.
  • moving means 11 are foreseen, mechanically connected to the rotary carousel 3 to adjust the vertical position of the valve assemblies 5.
  • moving means 11 are preferably obtained with mechanical actuators (comprising, for example, trapezium-shaped threaded screws) connected to the support columns 37 of the tank 4 of the filling machine 1 to vertically move the tank 4 and simultaneously all of the valve assemblies 5 fixed peripherally onto it.
  • the moving means 11 are suitable for moving the valve assemblies 5 between at least one raised position, in which the valve assemblies 5 are separated from the rinsing containers 13 below, and at least one lowered position, in which the tap 44 of each valve assembly 5 is in sealed relationship with the corresponding rinsing container 13, brought into operative position by the first actuator means 76.
  • each rinsing container 13 comprises a first tubular body 51 fixed vertically to the second end of the arm 48 and closed at the bottom by a bottom 52 equipped with one or more draining holes 53.

  • the descent of the valve assembly 5 also brings the inner surface of the stepped seat 77 of the tap 44 to adhere on the upper portion 15 of the outer body 14 with the fourth gasket 70.
  • the descending thrust of the valve assembly 5 makes the second tubular body 54 of the rinsing container 13 slide downwards in the first tubular body 51, until the lower end 57 of the same second tubular body 54 goes into abutment against the bottom 52 of the first tubular body 51.
  • Such a lower end 57 is then hermetically closed by the projecting portion 59 of the bottom 52 that adheres in sealed relationship with the first gasket 60. In this way, no liquid can come out from the bottom of the rinsing container 13.
  • the lowering of the valve assembly 5 also ensures that the compensation cannula 68 enters, through the centring cone 9, into the chamber 27 defined by the same centring cone 9 and by the rinsing container 13.
  • the inner body 18 has its projecting element 24 resting on the lower limit switch 25 of the outer body 14. As described earlier, in this position, in which the inner body 18 is perimetrally enclosed by the outer body 14, a gap 28 remains defined between the lower wall 16 of the tap 44, the outer body 14 and the outer surface 29 of the inner body 18.
  • the subsequent washing step foresees supplying the sanitising liquid to one or more hydraulic circuits of the filling machine 1, which are connected through, for example, the opening of the poppet valve 71 to the auxiliary pipe 72.
  • the sanitising liquid coming from the auxiliary pipe 72 enters into the gap 28 through the second opening 73 of the outer body 14, also washing the outer surface 29 of the inner body 18.
  • the sanitising liquid passes through the passages 26 formed on the centring cone 9 arriving in the chamber 27. From here it rises both through the tubular pipe 6 and through the compensation cannula 68 to enter into a hydraulic sanitising circuit that comprises the tank 4. In this way, an accurate washing and a microbicide and anti-contamination treatment is ensured both of all of the parts of the filling machine 1 able to come into contact with the alimentary liquid to be bottled, and of the outer surface 29 of the inner body 18.
  • the poppet valve 71 of the sanitising circuit is closed interrupting the supply of sanitising liquid.
  • the moving means 11 lift the valve assemblies 5 from the rinsing containers 13 causing the extraction of the tubular profile 30 of the centring cone 9 from the cup 56 of the second tubular body 54.
  • the projecting portion 59 therefore, separates from the lower end 57 of the second tubular body 54 going past the first gasket 60 and allowing the sanitising liquid remaining inside the rinsing container 13 to be completely evacuated through the draining holes 53.
  • the first actuator means 76 bring the rinsing containers 13 back into their inoperative position.
  • the second actuator means 36 bring the first portion 35 of the separating casings 33 back in extended position and the moving means 11 bring the valve assemblies 5 back into their initial position to allow the filling operations to start up again.
  • the invention thus conceived therefore achieves the predetermined purposes.
