Definitions

  • the present invention relates to a method and an apparatus for producing prefilled containers filled with a liquid filling product by means of filling material introduced under pressure into the preform.
  • prefabricated blank which is produced for example by injection molding.
  • containers in particular bottles, are shaped in the blow-molding process by a molding gas flowing under pressure into a preheated preform and, in a second step, filled with a filling material, in particular with a liquid filling material.
  • Characteristic for the production of containers from preforms is that for the preform on the one hand and for the container on the other hand different molds for their production are used.
  • Extrusionblasclar Extrusionblasclar in which the molten raw material is extruded directly into a container contour predetermining blow mold and then inflated immediately. Production of a preform is omitted in these extrusion blow molding.
  • CONFIRMATION COPY can be shaped and filled. Such a method is known for example from DE 10 2010 007 541 A1.
  • a preform can be formed into a container, it is thermally conditioned, that is, in particular heated and provided with a suitable temperature profile.
  • the body of the preform is e.g. heated to about 120 ° C and malleable, while the mouth area may only reach significantly lower temperatures, since the preform is held at the mouth area in the forming and filling machine and may not deform under the usual holding forces there.
  • a device for producing filled containers has a heating section, along which the preforms are guided while being provided with the desired temperature profile.
  • the molding process must then proceed very rapidly so that the heat stored in the preform is sufficient to plastically deform the preform until completion of the molding process. Therefore, when molding with liquid product, the volume required for the molded container must be supplied to the preform under high pressure and within a short time interval. Typical filling times are in the range of 100 to 150 ms, whereby volume flows of up to 20 liters / s and more at pressures of up to 40 bar are required.
  • the beginning of the molding process is usually assisted by a stretch rod dipping into the preform, which mechanically applies pressure to the bottom of the preform to attract the preform, and subsequently takes over the guidance of the soil to allow the container to form symmetrically.
  • a minimum filling pressure dependent on the material and shape of the preform and the container to be produced is required, wherein at the beginning of the forming phase, a higher pressure may be advantageous in order to start the forming process.
  • piston pumps are used for the hydraulic shaping and filling of containers whose stroke volume corresponds to the required quantity of filling material or is adapted.
  • the piston is driven by a linear motor, hydraulically or pneumatically, and the filling material located in the cylinder of the piston pump is pressed into the preform or into the forming container.
  • reaction time of a piston pump is long compared to the filling time, so that in particular at the beginning of a molding and filling process, the desired volume flow is not achieved and a reproducible good distribution of the material of the preform can not be guaranteed in the molded container.
  • a plurality of containers can be filled in a time-overlapping manner at a plurality of filling stations.
  • the object of the invention is achieved by a method for producing filled with a liquid product containers from preforms by under pressure into the preform introduced contents, wherein the contents are pressurized by a pressure pump and at a forming and filling station by a filling valve in the Preform is initiated.
  • the inventive method is characterized in that a pressure accumulator arranged between the pump and the filling valve is pressurized by the pump when the filling valve is closed and filled with a volume of filling material and the Accumulator with an open filling valve emits the stored under pressure filling material to the preform.
  • the inventive method has the advantage that a continuously running pump can be used. Although such pumps can reach the required high pressures, but usually not required for the filling large volume flow.
  • the pump pressurizes the pressure accumulator with filling material under pressure according to the invention when the filling valve is closed, whereby the pressure accumulator fills with a volume of filling material.
  • a certain minimum pressure is required to deform the preform. Higher pressures can be used and are particularly advantageous in the initial phase of forming to initiate the forming process.
  • the beginning of the forming process can also be supported by a stretch rod.
  • the provision of a stretch rod is an embodiment which may be preferred.
  • a certain maximum pressure should also not be exceeded, on the one hand because the system components are not designed and on the other hand, because the transformation of the preform into the container is not controlled.
  • the pressure accumulator used should therefore advantageously have a preload pressure that corresponds to the minimum mold pressure.
  • the pressure of the accumulator increases when filled with the contents.
  • the pressure increase can be negligible or significant.
  • a preload pressure of 36 bar can be used, which increases to 40 bar when filled with the desired volume of contents. If the pressure reached in the store is higher than the desired maximum filling pressure, it is preferable to provide pressure reducers in front of the forming and filling station.
  • the pump must be able to apply the pressure that should be reached in the pressure accumulator.
  • the pump reaches a pressure corresponding to the maximum filling pressure. If the pump pressure is higher, in turn, appropriate means for pressure reduction are to be provided.
  • the design described above as an example has the advantage that the pressure built up in the pressure accumulator during the forming and filling process is initially high, whereby the deformation of the preform can be more easily set in motion. Supportive and leading the beginning of the transformation can be facilitated, for example, by a stretch rod.
  • the volume of the pressure accumulator should preferably correspond at least to the volume of the container to be formed and filled, ie essentially the volume of the mold in which the preform is formed into the container.
  • the volume of the pressure accumulator may also be higher, in particular if the method is implemented with a shaping and filling device, on which containers can be shaped and filled in a temporally overlapping manner at a plurality of forming and filling stations.
  • the object according to the invention is also achieved by a device for producing prefilled containers filled with a liquid filling material by means of a filling material introduced into a mold at a forming and filling station under pressure into the preform, which comprises a pressure pump and a filling valve, which are connected by a feed line connected to each other.
  • the device according to the invention is characterized in that it comprises a pressure accumulator which is arranged in the supply line between the pressure pump and the filling valve.
  • the pressure accumulator is preferably a gas pressure accumulator, which is biased at a pressure corresponding to the minimum forming and filling pressure.
  • the pump is preferably a continuously running pump. Any other type of pump capable of achieving sufficient pressure is also suitable.
  • the working pressure of the pump should preferably correspond to at least the minimum filling pressure, but preferably and preferably to the maximum filling pressure. At higher pressures, it is preferable to provide corresponding pressure limiters in the fluid path in front of the filling valve. Outside a molding and filling process, ie in particular when the filling valve is closed, the pump pressurizes the pressure accumulator with filling material under pressure. As long as the pressure achieved by the pump is greater than the pressure prevailing in the pressure accumulator, the pump pumps fluid into the pressure accumulator. In the pressure accumulator, a volume is stored which preferably corresponds at least to the volume required for a molding and filling operation, ie essentially the volume of the mold in which the preform is formed into the filled container.
  • the pump runs empty or the filling material is discharged via a return line with pressure relief valve.
  • the filling valve is opened. It is due to the features of the invention immediately the full form and filling pressure available, which was previously constructed in the pressure accumulator.
  • the volumetric flow required for the forming and filling process can be made available from the accumulator independently of the pump capacity.
  • a damping element in particular a gas pressure accumulator is suitable.
  • a gas pressure accumulator may be provided with a gas filling, which is completed by a membrane in the memory against the supply line.
  • a damping element a prestressed piston in a cylinder can be used, which can be biased for example by spring force or gas pressure. If at the end of a molding and filling operation a sudden increase in pressure occurs, this pressure increase is at least partially cushioned by the damping element, for example, the gas cushion is compressed in the pressure accumulator or the spring is tensioned and the pressure wave forming is damped in this way.
  • the pressure accumulator for this purpose should have a biasing pressure or a biasing force that corresponds to the maximum inflation pressure or slightly higher.
  • the pressure accumulator is not stretched at normal filling pressure in this way and retains its capacity for absorbing the pressure wave at the end of the molding and filling process.
  • alternative damping elements should be designed so that let the normal form and Gudenburg pass substantially unattenuated to the forming and filling station, but causes a damping of the sudden pressure increase at the end of the molding and filling process.
  • the abovementioned pressure accumulator is oriented relative to the forming and filling station so that the pressure wave propagating in the line system between the forming and filling station and the pressure accumulator meets the membrane at right angles, ie that the direction of propagation of the Pressure wave is perpendicular to the membrane. This is ensured in particular when the diaphragm of the pressure accumulator is perpendicular to the axis of the preform. Due to the special propagation of waves in thin lines and the reflection on the cable walls, this effect can also be achieved with correspondingly curved lines in a different orientation.
  • the damping element For effective damping of the propagating pressure wave and the protection of the widest possible areas of the device, it is advantageous to arrange the damping element near the forming and filling station, in particular near a forming and filling head of the mold and filling station. Thus, it can be ensured that the pressure wave can propagate only in a spatially very limited area of the device and is effectively damped. More remote components of the device are effectively protected.
  • the pressure strokes which can hardly be determined at their pressure, can thus be controlled with only one simple element. System parts are protected against pressure surges where safety valves can no longer work.
  • Figure 1 shows schematically the structure of an embodiment of a device according to the invention.
  • the illustrated apparatus has a forming and filling station 3, in which a preform 1 is transformed inside a mold 4 into a filled container.
  • the forming and filling station 3 has a forming and filling head 5 with a filling valve 6 which is connected to a supply line 2, through which the filling and filling station 3 contents can be supplied from a reservoir 9 under pressure.
  • the forming and filling head 5 is placed sealingly on the mouth of the preform 1 and the preform 1 within the filling time of a maximum of 150 ms filling material supplied at a pressure of 36 to 40 bar.
  • a maximum of 150 ms filling material supplied at a pressure of 36 to 40 bar For a 1, 5-liter bottle, this requires a volume flow of the contents of at least 10 l / s.
  • the device is equipped with a pump 7, which runs continuously and reaches a pressure of 40 bar.
  • the supply line 2 is provided behind the pump with a check valve 8.
  • the device has a pressure accumulator 10 preloaded with a gas.
  • the pressure accumulator is biased with, for example, 36 bar and can at a pressure of, for example, 40 bar record a volume of, for example, 1, 5 liters.
  • the running pump 7 sets the contents in the supply line 2 under a pressure of 40 bar, so that the gas is compressed in the pressure accumulator 10 and the accumulator 1, 5 liters of the contents absorbs. When the pressure of 40 bar is reached, the pressure accumulator no longer absorbs any other contents.
  • the pumped by the pump 7 filling material is passed through the pressure relief valve 11 and the return line 12 back into the reservoir 9.
  • the filling valve 6 can be opened.
  • the stored in the pressure accumulator 0 filling material flows under the initial pressure of 40 bar and high volume flow through the forming and filling head 5 in the preform 1, which transforms under the action of the contents within the mold 4 into the container and is filled at the same time.
  • the pressure in the accumulator 10 drops to 36 bar, which is sufficient for container molding.
  • the pressure accumulator 10 reacts quickly and without delay and, in contrast to the pump 7, can provide the volume flow required for the short filling time.
  • the container can thus be formed from the thermally conditioned preform 1, before the temperature of the preform 1 falls so far that it is no longer malleable.
  • the molded container can be separated from the forming and filling head 5 and further processed, in particular by closing, labeling, etc.
  • the pump 7 continues to run continuously and refills the pressure accumulator 10 for the next forming and filling operation.
  • the device according to the invention has the advantage that a simple pump 7 can be used with a conventional liter capacity, since the short-term required for the molding and filling high volume flow can be stored by the pressure accumulator 10 and dispensed as needed.
  • the liter capacity of the pump 7 must be designed to correspond to the amount of filling per unit time.
  • the high volume flows required during the molding and filling phase are achieved by filling and emptying the pressure accumulator 10.
  • the pressure accumulator 10 is thereby interpreted by the volume so that it can accommodate the container volume at the time when forming and filling a container.
