Definitions

  • the present invention relates to a piston assembly for pumping a liquid, particularly in a bottling plant.
  • a method that can be used in particular for volumetric filling is the use of a piston that performs stroke movements in a cylinder and displaces a defined volume of liquid with each stroke.
  • a defined volume can be sucked into the piston through a supply line from a reservoir.
  • the supply line is then shut off by a shut-off valve, which can also be designed as a non-return valve, so that no liquid can flow back into the reservoir.
  • the liquid inside the cylinder is then forced out of the cylinder by a piston stroke in the opposite direction and fed through a line to the container to be filled.
  • This can be done under different levels of pressure.
  • This process can be used to fill a container that has already been formed or to simultaneously form and fill a preform under high pressure. Cleaning is a problem when using such piston pumps. Strict hygiene regulations must be observed, particularly in the case of bottling plants for bottling beverages. This includes regular cleaning and disinfection, which should be carried out as quickly as possible to avoid downtime of the affected machine.
  • intervention in a machine for example by dismantling parts to be cleaned and disinfected, should be avoided as far as possible in order to prevent contamination of a machine by germs brought in from outside.
  • the areas of a machine that carry product should be isolated from the environment as far as possible and should be able to be cleaned without opening.
  • liquid can be pumped from a supply line into a container by moving the piston between two reversal points.
  • the volume supplied to the container is determined by the working path of the piston and the diameter of the cylinder.
  • the piston and cylinder form a seal against one another. This can be done without a seal by means of an exact fit between the piston and the cylinder with a non-contact gap seal or by a seal on the piston to the raceway in the cylinder.
  • the diameter of the cylinder should be enlarged in one section beyond one of the two reversal points outside of the working path.
  • the cylinder diameter should be enlarged in such a way that the sealing closure is eliminated.
  • the piston should be able to be moved into this area for a cleaning and/or disinfection process.
  • the piston describes strokes between the two reversal points and thus pumps a defined volume of liquid from a reservoir into a container.
  • the piston is then moved into the area of the cylinder with the enlarged diameter, which represents a cleaning chamber.
  • the flask can also be disinfected there.
  • the term cleaning chamber should always be used here, even if disinfection can be carried out there.
  • the sealing effect of the piston relative to the cylinder wall is eliminated and a cleaning and/or disinfecting medium can be applied to the piston and cylinder barrel including any seals that may be provided. It is no longer necessary to dismantle the arrangement or other interventions from the outside.
  • a cylindrical shape does not necessarily have to be present in this area, even if this is advantageous.
  • the term cylinder should be used throughout here, even if it goes without saying for the person skilled in the art that in areas in which pistons and cylinders do not make contact, the shape does not necessarily have to be cylindrical, but also oval, polygonal or any shape can be different.
  • the sole decisive factor is that the diameter is expanded in such a way that there is no longer any sealing effect between the piston and the cylinder.
  • Liquid or foaming media are particularly suitable as the cleaning and/or disinfecting medium.
  • the supply of steam is also possible.
  • the diameter of the cylinder increases with continuous transitions and/or with large radii. This ensures that the piston can be moved from the cleaning position into its working area without getting caught or jammed.
  • the section with the enlarged diameter of the cylinder is provided with nozzles for supplying a cleaning and/or disinfecting medium.
  • cleaning and/or disinfecting medium can be introduced into the cleaning chamber in a targeted manner.
  • the piston is provided with a peripheral seal, and this area of the piston can be directly and specifically applied with cleaning and/or disinfecting medium.
  • the piston and seal can be made in one piece so that there are no hidden areas that are difficult to clean and disinfect.
  • the seal can in particular be a sealing lip running around the piston.
  • Piston and seal can be made of plastic, in particular of polyethylene (PE), polypropylene (PP) or polyethylene terephthalate (PET).
  • the diameter of the cylinder beyond the enlarged diameter section can again have the diameter of the area of the working path.
  • the piston and cylinder can seal beyond the enlarged diameter portion of the cylinder.
  • the piston arrangement can advantageously have a liquid line and two valves arranged in the liquid line.
  • at least one valve thereof can be designed as a non-return valve.
  • any other regulation or control of the valves is also possible.
  • One of the valves can be arranged in the liquid line upstream of the piston and/or one valve downstream of the piston.
  • a valve can also be arranged in the piston. In this case, liquid can be supplied through the piston.
  • FIG 1a an exemplary embodiment of a piston arrangement according to the invention is shown schematically, with which liquid filling material can be sucked in from a reservoir, not shown, and fed to a container.
  • a piston 1 is arranged in a cylinder 2 for this purpose.
  • the piston seals with the lip seal 3 with the running path of the cylinder 2.
  • the piston moves over a working path A between a first reversal point U1 and a second reversal point U2.
  • the diameter DZ of the cylinder and the length of the working path A are dimensioned such that the piston 1 displaces the volume that is to be filled into the container during its downward movement from the first reversal point U1 to the second reversal point U2.
  • the piston 1 is driven by any drive 4.
  • the force required for this depends on the pressure required with which the filling material is to be filled. In principle, this process is suitable for all common filling or forming and filling processes. Non-carbonated beverages can be filled at relatively low pressure, while carbonated beverages require slightly higher pressure. If a container is to be formed from a preform at the same time as the filling, a significantly higher pressure is required.
  • the piston sucks in filling material from a storage container, not shown, through the check valve 5 and with the shut-off valve 7 open, which flows in from the storage container in the direction of the arrow V.
  • the filling valve 6 is closed.
  • the filling valve 6 is opened and the piston is moved from the upper reversal point U1 to the lower reversal point U2.
  • the filling material flows in the direction of arrow B to the container, not shown here.
  • the arrangement has a cleaning chamber 8, here above the working path of the piston 1, in which the diameter DR of the cylinder is enlarged in such a way that the piston no longer seals with the cylinder.
  • Piston 1 is here, as in Figure 1b shown, freely accessible from all sides and can be charged with a cleaning and/or disinfecting medium.
  • Nozzles 9 are provided for this purpose in the cleaning chamber,
  • valves 6 and 7 are used to close the inlet and outlet lines.
  • Piston 1 is, as in Figure 1b shown, driven up into the cleaning chamber 8, and through the nozzle 9 cleaning and disinfecting medium is supplied. This can be done in several steps with different media.
  • the introduced cleaning and disinfecting media flow through the arrangement and are withdrawn again via the drain line 10, for which the valve 11 of the drain line 10 is opened.
  • the machine can be put back into operation after cleaning and disinfection is complete, if necessary after another rinse, by lowering the piston 1 to the working position, closing the valve 11 of the drain line 10 and opening the valve 7 of the supply line again.
  • the drive 4 of the piston 1 is guided through a bellows 12 sealing the chamber 8 .
  • FIG. 2a and 2 B show to facilitate understanding of the invention, a generic embodiment of an arrangement that largely the embodiment of the Figures 1a and 1 b is equivalent to. Again shows Figure 2a the arrangement in the working position and Figure 2b in the cleaning position.
  • the cleaning and/or disinfecting media are supplied via the supply line 13 and the shut-off valve 14.
  • FIGS figures 3a and 3b show an embodiment similar to the embodiment according to FIGS figures 2a and 2 B , where in turn Figure 3a the arrangement in the working position and Figure 3b in the cleaning position.
  • the piston 1 is moved into the cleaning position in such a way that it seals again with the cylinder in the upper area and the cleaning chamber 8 is thus closed.
  • the area of the piston 1 around the seal 3, which comes into contact with the filling material, is located in the cleaning chamber 8 and can be subjected to cleaning medium by means of the nozzles 9 arranged there.
  • FIGS figures 4a and 4b show an embodiment similar to the embodiment according to FIGS figures 2a and 2 B , where in turn Figure 4a the arrangement in the working position and Figure 4b in the cleaning position.
  • the cleaning chamber 8 is arranged on the other side of the working position A of the piston 1 in relation to the product line 15, ie the piston 1 is lowered into the cleaning chamber 8 for cleaning.
  • figure 5 shows schematically a fifth embodiment of a generic piston arrangement without nozzles for supplying a cleaning and/or disinfecting medium in section, in which a non-return valve is arranged in the piston. With this arrangement it is possible to pump the liquid through the piston.
  • the piston 1 has a check valve 5 which, in the arrangement shown, allows liquid to flow from top to bottom.
  • the filling material is again supplied through the supply line 20 in the direction of arrow V. If the piston moves downwards, it pumps filling material in the direction of arrow B with the valve 6 open to a container (not shown here). After one pump cycle, the valve 6 is closed. The piston moves upwards, valve 5 opens and the filling material located above piston 1 can flow through the piston. On the next pump stroke, valve 5 closes as soon as the piston moves down and pumps the product towards the container. At the same time, filling material flows out of the reservoir.
  • a shielding element 22 as a seal, such as a bellows, as shown in this figure.
  • a membrane, a rolling membrane or a rolling bellows can also be used.
  • a shielding element 22 arranged in the flow path is exposed to high pressure and thus high wear.
  • the shielding element 22 can therefore, as in figure 6 shown, also be arranged on the outside.
  • the pressure prevailing in the flow path is then absorbed by the seal 23 .
  • a notch 24 is provided in the drive rod 4, which is located in the cleaning position of the arrangement in the area of the seal 23 and allows the seal to be flushed with the cleaning medium.
  • the shielding element 22 designed as a bellows seals the arrangement from the outside. The bellows only has to withstand the pressure under which the assembly is cleaned. This pressure is significantly lower than the pumping pressure of the piston.
  • the valve 5 in the piston must also be suitable for CIP cleaning. Such valves can be designed in different ways.
  • the piston 1 in this embodiment is hollow and has liquid passages 30 and 31 in the lower and upper heads, respectively.
  • a sealing element 32 here a circular plate, which is vertically movable on the pin 33. If the piston moves up, as in Figure 7a shown, the sealing element 32 is on the pin in the lower stop 34 and liquid can flow through the piston 1 in the direction from top to bottom.
  • FIGs 8a and 8b is an alternative embodiment of the arrangement of the Figures 7a and 7b shown.
  • the sealing element 32 is a ball here, which seals against a seat on a pipe extension 36 .
  • Several such elements can be arranged in a piston.
  • One option for CIP cleaning of circumferential seals on cylindrical bodies, such as pistons, can also be to provide a number of seals spaced apart from one another.
  • the piston can then be brought into a position, as described above, in which the seals are in a cleaning chamber in which the seals have no contact with the surrounding cylinder in the working position, in order to be able to carry out cleaning.
  • All of the seals can be located in a single cleaning chamber, as described above, or individually in a single chamber.
  • a recess, z. B. can be in the form of a groove in the cylinder. Cleaning medium can penetrate between the cylinder and the piston right into the groove and enable cleaning.
  • the recesses can also be arranged in a staggered manner so that an individual seal can be cleaned at a time. Such a solution is in figure 9 shown.
  • the filling valve 6 can advantageously be integrated directly into a filling head 100, so that a minimal flow path is realized between the filling valve 6 and the preform or the container.
  • An exemplary filling head 100 within the scope of the invention is shown in 10 shown.
  • the filling head 100 consists of a filling chamber 102, which can be introduced via an inlet 104 for pressurized filling material and an annular gap 106, via which the filling material can be introduced into a preform or container, not shown.
  • the annular gap 106 can be closed by means of a valve insert 108 .
  • the valve insert includes a sealing surface 109 which interacts with a complementary sealing surface 109 ′ surrounding the annular gap 106 .
  • the valve insert 108 can be moved in the direction of the arrow 110 shown in order to close or open the annular gap 106 .
  • the valve insert 108 is mounted on the upper side of the pressure chamber 102 in a passage 112 in the side wall of the pressure chamber 102 and is sealed against the cylindrical passage 112 by means of a seal 114 . In the two operating positions for releasing and closing the annular gap 106, the seal 114 is always within the passage 112.
  • a bellows 116 is arranged above the passage 112 and is fastened firmly and tightly to the passage 112 on the one hand and to the valve insert 108 on the other hand. This results in a closed, variable-shape cleaning chamber 118 above the seal 114.
  • valve insert 108 For CIP cleaning, the valve insert 108 is brought into a cleaning position in which the seal 116 is arranged right into the cleaning chamber 118, so that an unsealed gap is created between the passage 112 and the valve insert 108, which connects the filling chamber and the cleaning chamber 118. At this point, the filling chamber 102 and the cleaning space 118 can be flushed together with suitable cleaning media, the surface of the valve insert including the sealing surface 109 and the seal 116 also being flushed with the cleaning medium.
  • a stretching rod 120 is provided, which is guided inside the valve insert 108 and sealed against it by means of a seal 122 .
  • the seal 122 is arranged in such a way that a sufficiently long travel of the stretch rod within the valve insert is made possible.
  • a gap is provided between the valve insert 108 and the stretch rod 120 , which widens the filling chamber 102 up to the seal 120 .
  • the stretch rod 120 there is a widening in the valve insert 108 which forms a cleaning chamber 122 .
  • the stretch rod is moved upwards until the seal 120 is arranged in the cleaning chamber 122 and the gap between the stretch rod 120 and the valve insert 108 connects the filling chamber 102 to the cleaning chamber 122 in a flow-conducting manner.
  • a second seal 124 on the stretch rod seals the cleaning chamber 122 upwards, so that the cleaning chamber, the gap between stretch rod 120 and valve carrier 108 and the filling chamber 108 can be flushed and cleaned together with a suitable cleaning medium.
  • the stretch rod is previously moved so far down that the seal 124 is arranged in the cleaning chamber 122, which is now using the Gasket 122 is sealed downwards.
  • the cleaning chamber 122 which is open at the top, can already be flushed with a cleaning medium, with the seal 124 being flushed and cleaned at the same time.
