The invention relates to a filling element according to the superordinate concept of claim 1 and a filling machine according to the superordinate concept of claim 18 .
Filling elements used in filling machines, particularly filling elements for filling bottles or similar containers with liquid fillers, even in rotating configurations, are known in different embodiments. In this case, so-called free injection filling elements are known, and the liquid filler flows as free injection from the exhaust opening of the filling elements into the container, which are spaced apart by the respective filling elements. Filling elements for so-called pressure filling or reverse pressure filling are known, and liquid fillers flow under pressure (filling pressure) into the filling phase in containers, each with a filling element.
In free-injection filling, the problem of trailing drops of the filling element essentially arises after the end of the filling phase and after removal of the filled container from the container support. This later drop can be blocked by the use of a gas block at the exhaust opening.
Of course, a filling element comprising a gas blocking part arranged in the exhaust opening for pressure filling of the carbon-containing filler is not suitable.
When the filling valve is closed or after the closing, a certain amount of liquid filler is suppressed in the flow path by being delayed to the upper part of the gas blocking part of the flow path. When the pressure valve is filled, the filling valve is closed. When the residual load is reduced, it is delayed to the upper part of the gas shut-off portion, and the opening of the contained carbon dioxide is led to the carbon-containing filler. As a result of this, the filling is pressed by the gas barrier and, as a result of significant contamination of the filling machine, it cannot withstand high sterilization requirements, especially during cooling aseptic filling.
If known filling elements are used for both free injection filling and pressure filling, therefore, is the gas barrier provided to avoid trailing drops during free injection filling removed? Or, conversely, it is necessary to assemble after pressure filling or before free injection filling, which means time-consuming and laborious replacement of each filling machine, which conditioned additional production costs as well as additional cleaning cycles.
Special table 2003-515510 gazette JP-T-2004-530599 German Patent No. 102004015167 German Patent No. 3903768 US Pat. No. 4,410,108 JP 2001-122394 A
The object of the present invention is to provide a filling element which allows a replacement between free injection filling and pressure filling without problems.
In order to solve this problem, the filling element is formed in accordance with claim 1. The filling machine is the subject of claim 18 .
The filling element according to the invention can be used selectively for free injection filling and pressure filling without disassembly of the gas barrier or new assembly. In both cases, the filling element operates without drops. During the pressure filling, the liquid filler is guided inside the filling element along the flow path or the liquid passage, and no gas blocking part is provided in the flow path or the liquid passage. The gas barrier is present in an additional flow path that is used as a return gas passage during pressure filling. In this case, the return gas is guided by the gas shut-off, which is possible without drawbacks. The replacement from pressure filling to free injection filling is done simply by shutting off the liquid valve used for pressure filling and opening another liquid valve, through which the liquid filler is added to the additional flow path. The flow path has an exhaust opening with a gas blocking part, so that the liquid filler can flow into the container to be filled as free injection through the exhaust opening with this channel and the gas blocking part.
Thereby, the replacement between both filling methods (free injection filling / pressure filling) can only be carried out by appropriate valve control without modification of the filling element. This gas barrier is not disassembled for replacement or reassembled.
The filling element according to the invention is suitable for free injection filling and pressure filling of bottles or similar containers, in particular for free injection filling and pressure filling of cylindrical containers. The reproduction of the invention is the subject matter of the dependent claims.
The invention will now be described in detail in an embodiment with reference to the drawings.
In the figure, reference numeral 1 denotes a filling element of a filling machine having a rotating configuration in which a bottle 2 is filled with a liquid filler. A filling element 1 is provided at the periphery of a rotor 3 which can be driven around a longitudinal machine axis together with a number of other filling elements and together with a bottle support 4 forms one filling position in the rotor 3. .
The filling element 1 is suitable for free-injection filling, in which each bottle 2 is spaced from the filling element 1 by its bottle communication part 2.1, so that the liquid filling material of each bottle can be used during the filling process. Since it flows in by the free injection 5, the capacity | capacitance of the air and / or gas which pushes a filler into a bottle can reach the circumference | surroundings freely in the area | region of the bottle communication part 2.1.
Furthermore, the filling element 1 is suitable for filling the bottles 2 under pressure (pressure filling), and the bottles 2 are each filled by their bottle communication part 2.1 in accordance with FIG. 3 during the filling process. It is in sealing contact with the element 1.
In detail, the filling element 1 consists of a single housing 6, in which a branched flow passage is formed, which is formed by both flow paths 7 and 8. A common connection passage 9 is attached to these flow paths, and the liquid filler is supplied from the external coupling portion 10 through the common connection passage when filling. The connecting passage 9 simultaneously forms a measuring section of the measuring device 11 (MID-sensor), and the amount of the filling material flowing into the respective bottles 2 at the time of filling is detected by the measuring device in order to control the volume of the filling process. The
The flow path 7 is formed by a ram passage 12.1 that is open at both ends of a tubular ram 12 that partially defines the filling element axis FA by an axis, and the ram 12 is transferred to the tube member 13 at the lower housing surface 6.1. The gas blocking part 13.1 is arranged on the tube member, and the tube member forms a short filling tube for free injection filling. In the case of the simplest gas barrier 13.1, it is a sieve-like insert with a large number of openings or an insert with a large number of passages, each of which is a liquid in the ram passage 12.1 and the pipe member 13. It is also open at the lower end that forms the exhaust opening for the filler. The ram passage 12.1 communicates with the valve chamber 14 of the liquid valve 15 by the upper end, and the valve chamber 14 and thereby the ram passage 12.1 is controlled by the liquid valve, so that the branch points of both flow paths 7 and 8; Alternatively, it can be connected to the connection passage 9. The liquid valve 15 consists of a valve body 17 activated by an actuating device 16, in the embodiment in which the valve body is illustrated, perpendicular to the filling element axis FA about the valve stroke in order to open and close the liquid valve 15; Can be moved in an axial direction oriented with respect to the machine axis in the radial direction and cooperate with a suitable valve face 18.
The ram 12 is guided in the housing 6 or in a cylindrical housing part 19 formed in the housing so as to be movable in the axial direction around a predetermined process in the direction of the filling element axis FA, and the disc-shaped membrane packing 20 Under the use of radial packing 21, the packing seals the gap between the outer surface of the ram 12 and the cylindrical inner surface of the housing portion 19 surrounding this ram in the region of the housing portion 19. The ram 12 is elastically biased to its lowering state.
The flow path 8 is formed in the filling element in a manner similar to a normal liquid passage, and communicates with an annular exhaust opening 22 that surrounds the tube member 13 on the lower surface 6.1 of the housing 6, and this exhaust opening has a second liquid. A valve 23 is provided and is closed when the ram 12 is lowered. The lower end of the ram 12 is formed as a valve body 24 for the liquid valve 23, and the valve body cooperates with a valve surface formed in the flow path 8 in the vicinity of the exhaust opening 22.
The housing lower surface 6.1 is further provided with an annular centering element 25 which is spaced beyond the lower surface, and the centering element is provided with an annular packing 25.1 surrounding the exhaust opening 22. On the other hand, each bottle 2 is sealed and abutted when pressure-filled by the bottle communication portion 2.1.
In the illustrated embodiment, the valve chamber 14 is in communication with two controlled gas passages 26 and 27, which are provided with one controllable valve 26.1 or 27.1 in each gas passage. It has been.
In the embodiment of FIGS. 1 to 3, the container support 4 holds the bottles 2 suspended from the container support by the communication flange 2.2. In order to move the container support 4 up and down, the container support is held by a rod 28 oriented parallel to the filling element axis FA by its axis, and the rod is movable in the axial direction for the movement stroke. 6 and the rotor 3. The rod 28 and each container support 4 by the rod 28 are also urged to the lower process state lowered by the compression spring 29. The rod 28 and the container support 4 can be lifted from the lower process state by an actuating device 30 which cooperates with the upper end of the rod 28, for example in the form of a pneumatic piston-cylinder arrangement. The lower process state of the rod 28 and thereby the lower position of the container support 4 coincides with the position during free injection filling. For pressure filling, the rod 28 and the respective container support 4 are moved to the upper process position.
As the figure further shows, the tube member 13 with the gas blocking part 13.1 projects downwardly through the plane of the annular packing 25.1 and thereby through the exhaust opening 22, and the lower end of the gas blocking part 13.1. Is approximately at the same level as the lower edge of the alignment element 24.
A wall is indicated by 31, which has a filling element 1 with a lower end and an inner space 32 for cooling aseptic filling in which the container support 4 rotates, separated from the surroundings. A packing 33 is provided at the transition between the rotor 3 and the fixed wall 31.
For free injection filling, consistent with FIG. 2, the bottles 2 at the container inlet of the filling machine are moved to the filling positions formed by the filling element 11 and the associated container support 4 respectively, and each bottle 2 is The bottle axis is oriented to the same axis as the filling element axis FA or approximately the same axis, and is suspended and held by the communication flange 2.2. Moreover, the filling element 1 or the gas blocker 13. 1 is spaced from the lower end of the tube member 13 having 1. The opening of the liquid valve 15 guides the filling process, i.e. the liquid filling material comprises an external connection 10, a connection passage 9, a valve chamber 14, a ram passage 12.1 and a gas blocking part 13.1. And reaches the inside of each bottle 2 as free injection 5. The individual passage 8 and the annular exhaust opening 22 are closed by a liquid valve 23. The measuring device 11 measures the amount of filler that flows into each bottle 2 during the filling process. If the required filler volume is achieved, the liquid valve 15 is closed on the basis of the signal supplied by the measuring device 11, thereby ending the filling process. The filled bottles 2 are taken out from the container outlets by respective container supports 4 and supplied to a closing machine (closer). The use of the gas barrier 13.1 in the filling element 1 effectively avoids liquid filler drops after each bottle 2 is removed.
In order to empty the valve chamber 14 and the ram passage 12.1, one or both of the gas passages 26 or 27 can be activated against the surroundings or by a special control valve or by actuation of the gas valve 26.1 or 27.1. It can be opened to a gas passage formed in the rotor.
FIG. 3 shows the working mode of each filling element 1 during pressure filling. In this case, each bottle 2 is attached in a sealed state to the filling element 1 or the packing 25.1 by its bottle communication part 2.1 by the rise of the container support 4. The liquid valve 15 is closed in this working mode. By opening the control valve 26.1 or 27.1, the internal space 2 of the bottle 2 sealed in the filling element 1 is energized, for example via the valve chamber 14 or the ram passage 12.1, ie under pressure. Is acted upon by inert gas present. Since the filling material reaches the flow path 8 through the external connection portion 10 and the connection passage 9 having a filling pressure, it is moved to the upper stroke state based on the pressure of the ram 12 acting on the annular lower membrane packing 20 based on this. Since the liquid valve 23 is opened, the liquid filler flows into the respective bottles 2 along the inner surface of the bottle through the annular exhaust opening. The reverse gas pressed by the liquid filler from the bottle 2 is the gas shut-off section 13.1, at least one open gas passage 26 through the ram passage 12.1 and the valve chamber 14 used as a reverse gas passage in this working mode or 27 flows in. Controlled by the signal of the measuring device 11, it is terminated by the closing of the gas passages 26 and 27 and the liquid valve 23 when the desired filling pressure of the filling process is achieved.
FIG. 4 shows a filling element 1a for selectively free-filling or pressure-filling a cylindrical container 2a. This filling element 1a has a substantially larger packing 25a. 1 is different from the filling element 1 only. FIG. 4 shows the working state of the filling element 1 a in the case of free injection filling when the liquid valve 15 is opened. Pressure filling is achieved by a container or cylindrical container edge 2a. 1 is done.
FIG. 5 shows the so-called CIP-filling element during cleaning. For this purpose, the alignment element 24 is closed by the dish-like closing element 34, so that when the liquid valves 15 and 23 are opened, the front passage inside the respective filling element 1 is used for CIP-cleaning. Can be flowed through by a cleaning medium. In particular, as shown in FIG. 6, a dish-like closure element 34 is provided on the container support 4 and is pivoted about the axis of the rod 28 (double arrow A) of the container support 4 formed in the shape of a circular fan. Since it is brought to a position below the centering element 25, the actuation of the actuating element 30 can cause the closure element 34 to abut against the centering element 25 and thereby the centering element 25 on the lower housing surface 6.1. The cleaning clap is formed together, and the cleaning clap is connected to the pipe member 13 having the gas blocking portion 13.1 when the exhaust opening 22 is opened.
As further shown in FIG. 6, the circular fan-shaped container support 4 is provided with a single recess 35 or 36 next to the closure element 34 and has a different size so that the container support 4 is a rod. It can be adjusted in the region of the communication flange 2.2 on the bottle 2 with different diameters by 28 swivels.
This invention was previously described in the examples. It will be understood that numerous changes and modifications can be made without abandoning the inventive idea upon which the invention is based.
