Definitions
- the invention relates to a device for treating containers according to the preamble of patent claim 1. Furthermore, the present invention relates to a method for treating containers according to the preamble of patent claim 15.
- Systems for the aseptic filling of a liquid product into containers, in particular in bottles, cups or cans, are known in a wide variety of designs and are used, for example, for cold aseptic filling of heat-sensitive beverages (e.g. fruit juices).
- the individual machines which form such a system and which are connected to one another in the production or treatment line, e.g.
- the rinser, sterilizer, filling machine or closing machine are provided with housings, in such a way that there is a conveying path for the containers or bottles within the system in a sterile interior, which, because of this housing, is opposite adjacent non-sterile rooms or areas, for example the environment , in particular is sealed against the ingress of germs.
- such an enclosure when using machines of the rotating design, as is customary for rinsers, sterilizers, filling machines and / or closing machines, such an enclosure generally has several transitions between a rotating or
- Seals made of elastomeric material that slide on another part made of metal have the major disadvantage that they wear out quickly, which then also leads to a loss of the seal.
- Gap and / or labyrinth seals which solve the problem of wear of the seals have also proven themselves, since they do not bring any physical contact between the parts which are movable with respect to one another.
- the quality of the seal depends on the distance between the moving parts: if this distance decreases, the quality of the seal increases, but small distances can only be achieved with large machines at great expense and high costs.
- Labyrinth seal referenced. It is essential that the labyrinth seal represents the transition from rotating to non-rotating housing parts.
- the pressure of the sterile gas in the interior is kept higher than the pressure of the ambient air.
- a certain amount of the sterile gas constantly flows into the environment via the labyrinth seal, and this amount of sterile gas has to be continuously supplied to the interior via a gas line.
- the amount of sterile gas that flows from the interior into the environment depends on both the distances between the moving parts and the pressure difference between the interior and the environment. This pressure difference is usually kept as small as possible, but also as large as is necessary to prevent the penetration of ambient air and thus
- the object of the present invention is to provide an improved device and an improved method for treating containers under aseptic conditions, which in particular optimize the flow behavior of the sterile gas.
- a device for treating containers is proposed, the containers being, in particular, bottles, cups, cans and the like.
- the device has a stationary machine element, a rotating machine element and an interior.
- the rotating machine element can be a
- the container is circumferential transport element that holds and / or transports the containers. Further it is conceivable that the device has further rotating machine elements. When the containers are treated, they are predominantly or exclusively in the interior of the device. The interior is advantageously a sterile
- the interior is delimited by at least one first
- Machine element is assigned. Are other rotating machine elements
- Labyrinth seal formed and the pressure in the interior is kept higher than the air pressure in the environment, so that there is always a small gas flow from the interior through the labyrinth seal to the environment.
- the labyrinth seal is one
- annular channel-like slot wherein between the stationary and the rotating part of the machine element an annular channel-like slot is formed, which in cross section resembles a labyrinth.
- the annular channel-like slot has an inner channel end facing the interior and an outer channel end facing away from the interior.
- the special sealing effect of the labyrinth seal is based on the fact that the labyrinth extends the flow path from the interior to the surroundings, which also increases the flow resistance. Given a pressure difference between
- the gas flow through the labyrinth seal is therefore relatively low in the interior and surroundings.
- the device has a rotatable vacuum device which is arranged in the region of the outer channel end and has at least one wing element.
- the at least one wing element creates a depression in the labyrinth seal and / or a gas flow directed from the inner channel end to the outer channel end. This supports the flow of the sterile gas from the interior to the environment and at the same time further suppresses the flow of ambient air into the interior.
- the flow behavior of the sterile gas is thus significantly improved, so that the pressure difference between the interior and environment can be kept small and less sterile gas into the
- the rotating machine element rotates about a first axis of rotation and the
- the vacuum device can be rotated about a second axis of rotation.
- the first axis of rotation particularly advantageously coincides with the second axis of rotation. Then the at least one wing element rotates along the outer channel end and the oppression in the labyrinth seal or that from the inner channel end to the outer one
- Channel end directed gas flow is even along the circumference of the
- Machine element is firmly connected and / or part of the rotating
- Vacuum device with the advantages mentioned above.
- the vacuum device can be rotated by a motor and in particular has its own drive. Then the vacuum device can be operated independently of the rotating machine element. For example, the vacuum device can then also be operated in the event that the rotating machine element has to stop for a short time due to operational reasons and generate the necessary negative pressure in the labyrinth seal or the gas flow from the inner channel end to the outer channel end. Furthermore, the rotational speed of the
- Vacuum device selected regardless of the speed of rotation of the rotating machine element and thus the strength of the vacuum in the
- Labyrinth seal or the gas flow from the inner to the outer channel end can be determined.
- the at least one wing element is advantageously bent and / or rotated or rotatable with respect to a tangential direction to the second axis of rotation.
- a wing element bent from an aerodynamic point of view is indeed at most complex, but can produce a stronger suppression compared to a straight wing element of the same size and rotating at the same speed.
- a rotation or a pivoting of the wing element in relation to the tangential direction to the second axis of rotation can increase the suppressions generated.
- the wing element can have a constant inclination to the tangential direction, which is particularly easy to implement in terms of construction. However, the wing element can also be rotatable, so that its inclination to the tangential direction can be adjusted.
- Changing the incline can, for example, the strength of the negative pressure
- Vacuum device or a changed pressure difference between the interior and surroundings can be compensated.
- Has wing elements which are stored individually or in groups. A plurality of in particular evenly distributed wing elements result in a more constant one
- each wing element is individually rotatably mounted, the inclination of each wing element to the tangential direction to the second axis of rotation can be changed individually in order to obtain certain flow conditions. However, if the wing elements are mounted in groups, several wing elements are adjusted at the same time by adjusting the inclination.
- the vacuum device comprises an adjusting device which adjusts the inclination of the wing element or the wing elements to the tangential direction to the second axis of rotation.
- This adjustment device can be designed in a variety of ways, for example as a manual adjustment device which is operated by operating personnel or as an automatic adjustment device which detects the inclination of the wing elements
- one or more cover element are provided which at least partially cover the outer channel end. This covering of the outer end of the channel makes possible entry of non-sterile Ambient air in the sterile interior is further suppressed.
- the cover elements can contribute to the fact that the generated by the vacuum device
- the cover element (s) are firmly connected to the vacuum device or constitute part of the vacuum device
- Interaction of the cover elements with the vacuum device can ensure particularly good protection against the penetration of non-sterile ambient air into the sterile interior in the area of the outer channel end.
- a further channel is provided, one end of which is located in the region of the outer channel end.
- the further channel has no direct connection to the interior, can be subjected to a vacuum and is in particular covered by the cover element (s).
- a targeted air flow can be generated in the area of the outer end of the duct via this additional duct. This air flow makes it difficult for other air flows to let non-sterile air get into the interior.
- the application of negative pressure can also take place via the negative pressure device.
- the further channel has one or more openings through which gas can be supplied.
- the flow conditions in the further channel can be controlled even more precisely.
- one or more can advantageously
- Filter elements to be attached to the or the openings, which from the outside to the
- a reservoir with cleaned gas can be realized, for example, by a closed ring channel which is connected to a compressor and a gas filter via a gas feed line.
- At least one line leading into the interior for sterile and / or sterilizing media and associated outlets in the interior are provided. It can, for example, in
- Sterilization of the interior can be carried out at regular intervals or as required.
- a method for treating containers is also proposed.
- the containers are treated in a device which has a stationary machine element, a rotating machine element and an interior.
- the interior is delimited by at least a first wall section and a second wall section, the first wall section being the stationary machine element and the second
- Wall section is assigned to the rotating machine element.
- a labyrinth seal is formed between the first and the second wall section, which has an annular channel-like slot with an inner channel end facing the interior and an outer channel end facing away from the interior.
- the rotating machine element is rotated, for example in order to transport containers held by the rotating machine element.
- the method is carried out by means of a device according to
- this device has a rotatable negative pressure device which is rotated in the present method, so that a negative pressure is generated in the labyrinth seal and / or a gas flow directed from the inner channel end to the outer channel end. This improves the flow behavior of the sterile gas in particular.
- FIG. 1 shows a schematic section through an inventive device for treating containers
- FIG. 2 shows a schematic section through a detail of a further embodiment variant of a device for treating containers according to the invention
- FIG. 3 shows a schematic section through a detail of yet another
- FIG. 4 shows a schematic section through yet another embodiment variant of a device according to the invention for treating containers
- 5a is a purely schematic side view of a wing element
- 5b is a purely schematic side view of a group of wing elements.
- FIG. 1 shows a schematic section through a device 1 for treating containers 2.
- the device 1 can be, for example, a rinser, a sterilizer, a filling machine and / or a closing machine.
- the containers 2 are shown in Figure 1 as bottles, but the invention also relates to other containers 2, such as cups or cans or the like.
- the containers 2 are located in an interior 3 of the device 1 during the treatment. This interior 3 is designed as a sterile interior, so that the device 1 is suitable, for example, for cold aseptic filling of heat-sensitive beverages such as fruit juices.
- the device 1 has, in addition to many other components, which are, however, not essential to the invention and are therefore not shown in the schematic figures, a stationary machine element 4 and a rotating machine element 5.
- the rotating machine element 5 comprises holding devices 6 which hold the containers 2 and transport them when the rotating machine element 5 rotates.
- the rotating machine element 5 is rotated about a first axis of rotation RA1.
- At least one labyrinth seal 9 is provided between the first wall section 7 and the second wall section 8 to prevent the penetration of non-sterile ambient air into the interior 3.
- the gas pressure in the interior 3 is preferably kept greater than the air pressure of the ambient air, so that a somewhat sterile gas can always flow into the environment via the labyrinth seal 9, which in turn prevents the inflow of ambient air into the interior 3
- the labyrinth seal 9 has an annular channel-like slot 10, which extends the flow path from the interior 3 to the surroundings through its labyrinth-like cross section and thus increases the flow resistance between the interior 3 and the surroundings. Due to the increased flow resistance, the flow of the sterile gas from the interior 3 into the environment and thus the loss of sterile gas is reduced.
- the annular channel-like slot 10 has an inner channel end 11 facing the interior 3 and an outer channel end 12 facing away from the interior 3.
- the device 1 has a rotatable vacuum device 13 which is arranged in the region of the outer channel end 12 and which in this exemplary embodiment represents part of the rotating machine element 5.
- the rotatable vacuum device 13 which is arranged in the region of the outer channel end 12 and which in this exemplary embodiment represents part of the rotating machine element 5.
- Vacuum device 13 has at least one wing element 14, preferably a plurality of wing elements 14, which generate a depression in the labyrinth seal 9 and / or a gas flow directed from the inner channel end 11 to the outer channel end 12 when the vacuum device 13 rotates. This suppression or gas flow makes it more difficult for non-sterile ambient air to enter sterile interior 3.
- FIG. 2 shows a section through a further device 1 for treating containers 2 in the area of the labyrinth seal 9. In comparison with device 1 of the exemplary embodiment described in FIG.
- Cover element 15 is provided, which is firmly connected to the stationary machine element 4 and covers the outer channel end 12 at least in sections. The at least partial covering of the outer duct end 12 further complicates the entry of contaminated air into the interior 3.
- a further channel 16 is provided, the upper end of which lies in the area of the outer channel end 12 and is also covered by the cover element 15.
- the further channel 16 is implemented, for example, in the form of a through hole.
- the further channel 16 is also acted upon by a suppressor. This leads to a gas flow through the further channel 16.
- the lower opening 17 of the further channel 16 is connected to the ambient air, so that the gas flow is a flow of ambient air. Since this is a directed flow, the entry of contaminated air into the interior 3 is made even more difficult.
- a filter pack 30 is shown in dashed lines in FIG. 2, which can optionally be attached to at least one or all openings 17 and thus prevents the entry of foreign or harmful substances into the sealing area.
- the opening 17 of the further channel 16 is connected to a reservoir with cleaned and / or sterile gas.
- a gas flow with cleaned and / or sterile gas is generated in the further channel 16, so that the entry of contaminated air into the interior 3 is made even more difficult.
- Figure 3 shows a section through a further embodiment of the
- the cover element 15 forms part of the vacuum device 13, for example via a detachable connection a screw connection 18 is firmly connected to the rotating machine element 5.
- the cover element 15 preferably has opening slots 19 arranged on the edge and / or in the area of the wing elements 14, which ensure that the negative pressure generated by the wing elements 14 when the vacuum device 13 rotates causes an outward gas flow in the opening slots 19, which in turn causes has a suppression in the area of the outer channel end 12.
- This exemplary embodiment also enables the generation of defined flow conditions in the region of the outer channel end 12 of the labyrinth seal 9 and thus offers good protection against the ingress of contaminated ambient air into the sterile interior 3.
- FIG. 4 shows a schematic section through a further embodiment variant of the device 1 according to the invention for treating containers 2.
- the vacuum device 13 in this exemplary embodiment is not connected to the rotating machine element 5, but rather can be rotated by a motor via at least one of its own drives 20 formed, and preferably rotatable about a second axis of rotation RA2.
- this is structurally complex, it enables the vacuum device 13 to be operated independently of
- the first and second axes of rotation RA1, RA2 preferably coincide.
- the vacuum device 13 with its own drive 20 is particularly advantageous when the rotating machine element 5
- Vacuum device 13 can be rotated further by its own drive 20 and ensure the desired gas flow conditions in the area of the outer channel end 12.
- a line 21 for sterilizing media is provided with an outlet 22 located in the interior 3.
- This line can be used to introduce sterilizing media into the interior 3 at predetermined time intervals or, if necessary, to restore the sterile conditions in the interior 3.
- FIG. 5 a shows a schematic side view of a curved wing element 14.
- the bending of the wing element 14 is so from an aerodynamic point of view chosen that the negative pressure generated in the area of the outer channel end 12 reaches a predetermined size and / or is as constant as possible.
- FIG. 5b shows a group of wing elements 14 that can be rotated about a pivot point 23 in each case
- Connecting wing elements 14 forms an adjusting device 26 for the inclination of the wing elements 14.
- the adjusting device 26 can be used to adjust the inclination of the wing elements 14.
- the adjusting device 26 can also be controlled by a motor, hydraulically or pneumatically and also an automatic control of the inclination of the wing elements 14, for example depending on the speed of rotation of the vacuum device 13, the pressure difference between the interior 3 and the environment and / or the degree of pollution of the ambient air is conceivable.
