Description

Technical Field

[0001] The invention relates to a device for filling containers. The invention also relates to a method of operating a device for filling containers. Background Art

[0002] Filling devices for filling containers are already known in the prior art. According to the prior art, such filling devices can be cleaned with a liquid cleaning agent in the context of a cleaning mode. This cleaning agent can be supplied, for example, via a product supply line in order to clean the individual filling elements. The cleaning agent can then be returned using a so-called CIP cap (CIP, English: cleaning in place) or cover.

[0003] DE 37 22 495 A1 discloses a filling and sealing machine for containers such as bottles, cans, plastic containers, etc., which consists of the following parts: a rotating support for filling valves, sealing components, etc.; a chassis and a lifting mechanism associated with these filling valves and sealing components; a rinsing container that can be placed between these chassis and lifting mechanisms and can be placed at the filling valve or sealing device, for collecting and guiding the cleaning liquid that circulates during the rinsing process. The corresponding rinsing container in or at the filling and sealing machine is supported in a way that it can be automatically moved from a static position outside the movement path of the container into a working position below the filling valve and sealing component. The rinsing container is installed in or at the actual lifting mechanism and is moved from a static position to a working position in or at the lifting mechanism and can be moved relative to the filling element by the lifting mechanism.

[0004] For further prior art, please refer to EP 1 270 498 A1, JP S52 047042U, EP 2 748 102 B1, EP 0 785 134 A2, DE 10 2006 013 367 A1, DE 10 2014 117 859 A1, DE 43 43 425 A1 and DE 10 2011 111 496 B3.

[0005] A disadvantage of the prior art is that a system for moving the cleaning cover of the rinsing container or the filling mechanism may require a relatively large space, especially when the filling mechanism also has an elongated filling level probe that needs to be cleaned together. In practice, this results in the fact that in the case of a small footprint, for example due to the relatively small spacing of the filling stations of a circular carousel (such as 87 mm or 94 mm), it is sometimes still necessary to manually install and remove the CIP cleaning cover. Summary of the invention

[0006] The object of the present invention is to provide an improved technique for cleaning a filling mechanism of a filling device, which technique preferably has a particularly small space requirement and / or is suitable for filling mechanisms having a filling level probe.

[0007] This object is achieved by the features of the independent claim. Advantageous developments are given in the dependent claims and in the description.

[0008] One aspect of the disclosure relates to a device for filling containers, preferably a circular rotating device. The device has (at least one) filling mechanism for filling the container. The device also has (at least one) container holder, preferably a container support plate, for supporting the container (e.g. at the bottom) when filling the container. The device also has (at least one) (e.g. tubular) cleaning cover, preferably a CIP cleaning cover, for covering the filling mechanism when cleaning the filling mechanism. The device also has (at least one) replacement system, which is designed to, for cleaning the filling mechanism, move the container holder from a (e.g. use) position directly below the filling mechanism (e.g. to a non-use position of the container holder laterally offset relative to this position), preferably pivot away (about a single pivot axis), and move the cleaning cover (e.g. from an inverted non-use position of the cleaning cover), preferably pivot to a (e.g. use) position directly below the filling mechanism, particularly preferably about several pivot axes spaced apart from each other (e.g. parallel).

[0009] Advantageously, the replacement system makes it possible to use only a very small amount of space. The container holder can be moved away from the position directly below the filling mechanism in order to create space for the cleaning cover. In this way, CIP cleaning with automatic positioning of the cleaning cover is possible even for filling mechanisms with a filling level probe and relatively small spacing.

[0010] In one embodiment, the changing system is further designed to couple the movement of the container holder and the movement of the cleaning cover to one another, preferably mechanically. Preferably, the movement of the container holder away from its position directly below the filling mechanism (e.g. pivoting away) and the movement of the cleaning cover to its position directly below the filling mechanism (e.g. pivoting away) can be coupled to one another, preferably mechanically. Alternatively or additionally, for example, the movement of the container holder to its position directly below the filling mechanism (e.g. pivoting away) and the movement of the cleaning cover to its position directly below the filling mechanism (e.g. pivoting away) can be coupled to one another, preferably mechanically. Advantageously, the movement of the container holder and the cleaning cover can thus be realized by a common drive device, thereby making a particularly space-saving solution possible.

[0011] In a further embodiment, the changing system has a pivoting device, which preferably has several pivot axes, and / or a lifting device (e.g. a pneumatic cylinder-piston unit) with a movable lifting element, preferably a lifting piston, for moving the container holder and the cleaning cover. Advantageously, the container holder and the cleaning cover can thus be pivoted and / or lifted by the changing system.

[0012] In one embodiment, the pivot device connects the movable lifting element with the container support and the cleaning cover. Advantageously, the movable lifting element can be used to realize the common mechanical coupling of the container support and the cleaning cover via the pivot device, thereby for example only the lifting device is required to drive the container support and the cleaning cover.

[0013] In a further embodiment, the replacement system is further designed as follows:

[0014] a first section of the stroke of the movable lifting element causes the container holder to be pivoted away from its position directly below the filling mechanism by means of the pivot device and the cleaning cover to be pivoted into its position directly below the filling mechanism; and

[0015] The second section connected to the first section enables the container holder and the cleaning cover to be lifted and moved toward the filling device.

[0016] Advantageously, such configuration makes it possible that: only a lifting device is required to remove the container support, pivot the clean cover to the position and lift the clean cover. Advantageously, the clean cover can be oriented upside down in the non-use position by pivoting, thereby the clean cover can be emptied easily.

[0017] In one embodiment variant, the filling mechanism has a centering bell, into which the cover opening of the cleaning cover can be inserted and which can be displaced in a vertically guided manner (for example by a vertical guide of the filling mechanism) for vertically guiding the container holder in the second section of the lifting stroke. Advantageously, a separate vertical guide for the cleaning cover can thus be omitted, thus particularly saving space.

[0018] In another embodiment variant, the pivot device has (at least one) lever element,

[0019] - the (eg first) end of the lever element is guided at a guide curve, preferably at a guide curve groove; and / or

[0020] - the (for example second) end of the lever element is mounted on the container holder; and / or

[0021] - the lever element is pivotably connected between a first end and a second end, preferably horizontally, to a movable lifting element of the lifting device; and / or

[0022] The (for example third) end of the lever element is pivotably connected, preferably horizontally, to the cleaning cover.

[0023] Advantageously, a desired pivoting movement of the container holder can thus be fully realized by the lifting device and optionally also partially enabled for a desired pivoting movement of the cleaning cover.

[0024] In another implementation variant, at least one of the following is satisfied:

[0025] - the guide curve is enclosed in the housing part, preferably on the inner side of the housing part;

[0026] - the guide curve is fixed relative to the stationary part of the lifting device, preferably the lifting cylinder;

[0027] - the guide curve has a stepped shape; and

[0028] - The guide curve has a first substantially vertical guide curve section, a second substantially inclined or horizontal guide curve section connected to the first guide curve section, and a third substantially vertical guide curve section connected to the second guide curve section, optionally with a (e.g. conical) widening outlet end.

[0029] Advantageously, a desired pivoting movement of the container holder can thus be fully realized by the lifting device and optionally also partially enabled for a desired pivoting movement of the cleaning cover.

[0030] In one embodiment, the pivot device has (at least one) pivot arm,

[0031] - the (eg first) end of the pivot arm is pivotably connected, preferably horizontally, to a movable lifting element of the lifting device; and / or

[0032] The (eg second) end of the pivot arm is pivotably connected, preferably horizontally, to the cleaning cover.

[0033] Advantageously, the desired pivoting movement of the cleaning cover can thus be partially enabled by the lifting device.

[0034] Preferably, the pivot arm and the lever element are connected to the movable lifting element via several pivot axes spaced apart from one another, preferably spaced apart vertically, preferably parallel, and / or the pivot arm and the lever element are connected to the cleaning cover via several pivot axes spaced apart from one another, preferably parallel, thereby advantageously making it possible to pivot the cleaning cover over a particularly large angular range without the lifting element having to have a large lift for this purpose. Advantageously, this also makes it possible to orient the cleaning cover upside down in the non-use position.

[0035] In one embodiment, the lever element is connected to the movable lifting element via a (e.g. first and / or horizontal) pivot axis, and the pivot arm is connected to the movable lifting element via a (e.g. second / other) pivot axis (e.g. vertically) spaced, preferably parallel, (e.g. horizontal) pivot axis. Alternatively or additionally, the lever element is connected to the cleaning cover via a (e.g. third / further and / or horizontal) pivot axis, and the pivot arm is connected to the cleaning cover via a (e.g. fourth / further additional) pivot axis (e.g. horizontal) spaced, preferably parallel, relative to the pivot axis. As previously mentioned, the cleaning cover can therefore be advantageously pivoted within a particularly large angle range, and the lifting element does not need to have a large lift for this purpose. Similarly, as previously mentioned, it is therefore advantageously possible to make the cleaning cover inverted in the non-use position.

[0036] In one embodiment variant, the lifting device has a lifting curve follower, preferably a roller, for following a (e.g. fixed) lifting curve portion (e.g. a lifting curve portion of the device). The lifting curve follower can preferably be operatively connected to the lifting element in order to vertically move the lifting element, preferably lift it. For example, the lifting curve follower can be arranged and, for example, supported at the lower end of the lifting element. Thus, a reliable, accurate and robust mechanical lifting device can be provided, which can move the lifting element without complex pneumatic systems.

[0037] In another embodiment variant, the device further comprises a locking device, preferably a mechanical locking device, which is configured to lock the lifting element, preferably automatically (e.g. elastically preloaded), when the cleaning cover is positioned (e.g. pivoted) in its position directly below the filling mechanism. Preferably, the locking device can be mechanically actuable to release the lifting element (e.g. mechanically). Alternatively or additionally, the lifting element can be elastically preloaded to be lowered, preferably in order to move the container holder into its position directly below the filling mechanism and / or in order to move the cleaning cover away from its position directly below the filling mechanism. Alternatively or additionally, the lifting element can be lockable by a locking element of the locking device at a boss of the (e.g. stepped) lifting element.

[0038] Advantageously, the locking device can make it possible for the lifting element (and therefore the cleaning cover and the container holder) to assume a defined position. For example, when the lifting element is locked, the cleaning cover can be securely positioned in its position below the filling mechanism. On the other hand, when the lifting element is unlocked, it is possible, for example, to move the container holder into its position directly below the filling mechanism. Then, under the effect of the elastic preload, the lifting element can, for example, always be moved in such a way that the container holder reaches and remains in its defined position directly below the filling mechanism.

[0039] In another embodiment, the replacement system is also designed to, in order to end the cleaning of the filling mechanism, move the container holder into, preferably pivot it into, its position directly below the filling mechanism and to move the cleaning cover away from its position directly below the filling mechanism, preferably pivot it away and / or into an inverted orientation of the cleaning cover. Advantageously, the cleaning cover can thus be moved away from the position directly below the filling mechanism in order to create space for the container holder for the normal operating mode / filling operating mode of the device.

[0040] In one embodiment variant, the changing system has a common and / or single drive source for moving the container holder from its position directly below the filling mechanism and also for moving the cleaning cover into its position directly below the filling mechanism, and optionally vice versa. Advantageously, a particularly space-saving arrangement can thus be made possible.

[0041] In another embodiment variant, the replacement system is also designed so that the cleaning cover is pivoted to its position directly below the filling mechanism over a greater angular range than the container holder is pivoted away from its position directly below the filling mechanism. Advantageously, this makes it possible to orient the cleaning cover upside down in the non-use position.

[0042] In one embodiment, the non-use position of the container holder and the (eg inverted) non-use position of the cleaning cover are arranged on opposite sides of the replacement system. Advantageously, a particularly space-saving arrangement and simple kinematics can thus be made possible.

[0043] In another embodiment, the filling mechanism has a filling level probe. The cleaning cover can be dimensioned to accommodate the filling level probe. Optionally, the replacement system can be designed to move the cleaning cover in such a way that the filling level probe is inserted into the cleaning cover for cleaning the filling mechanism. Advantageously, the cleaning cover can thus also be used in systems with a filling level probe.

[0044] In one embodiment, the device also has a lifting system, which is designed to jointly lift and lower the container support, the cleaning cover and the replacement system. Advantageously, the container supported on the container support can therefore be lifted and lowered in the normal operation of the device.

[0045] Another aspect of the present disclosure relates to a container processing device (e.g., for tempering, manufacturing, cleaning, coating, testing, filling, sealing, pasteurizing, labeling, printing, lettering, laser lettering and / or packaging containers for liquid or pasty media, preferably beverages, liquid foods or products from the pharmaceutical or healthcare industry). The container processing device can have an apparatus as disclosed herein.

[0046] For example, the container can be a bottle, jar, can, carton, vial, tube, etc.

[0047] Another aspect of the disclosure relates to a method for operating a (e.g. circularly rotating) device for filling containers, preferably as disclosed herein. The method comprises: switching to a (e.g. CIP) cleaning operating mode of the device by moving the container holder from a (e.g. use) position directly below the filling mechanism, preferably pivoting it away (e.g. about a single pivot axis) (e.g. to a use position of the container holder laterally offset relative to this position) by means of a replacement system, and moving a (e.g. CIP and / or tubular) cleaning cover (e.g. from an inverted non-use position of the cleaning cover), preferably pivoting it to a (e.g. use) position directly below the filling mechanism, preferably about several pivot axes spaced apart from each other (e.g. parallel). The same advantages that have already been described with reference to the device can advantageously be achieved using this method. This also applies to the preferred embodiments of the method described below.

[0048] In one embodiment, the method further comprises at least one of the following steps:

[0049] - ending the cleaning operating mode by moving, preferably pivoting, the container holder into its position directly below the filling mechanism by means of the changing system and moving, preferably pivoting, the cleaning cover away from its position directly below the filling mechanism, preferably into an inverted orientation of the cleaning cover;

[0050] - the container holder is moved away from its position directly below the filling mechanism, preferably pivoted away, and the cleaning cover is moved, preferably pivoted, into its position directly below the filling mechanism by means of a change system coupling, preferably mechanical coupling;

[0051] - the container holder is moved, preferably pivoted, into its position directly below the filling mechanism by means of a coupling, preferably mechanical coupling, of the changing system, and the cleaning cover is moved, preferably pivoted, away from its position directly below the filling mechanism;

[0052] - using the centering cover of the filling mechanism to guide the cleaning cover vertically towards the filling mechanism; and

[0053] - Immersing the filling level probe into the cleaning cover (eg while the cleaning cover is moved vertically upwards by means of the changing system, preferably guided by the centering bell).

[0054] - locking the cleaning cover in its position directly below the filling mechanism (e.g. self-locking and / or elastically preloaded) by means of a locking device, preferably a mechanical locking device, which preferably locks a lifting element of a lifting device of the changing system (e.g. at a boss of the lifting element); and

[0055] - elastically prestressing a lifting element of a lifting device of the changing system in order to lower the lifting element in order to move the container holder into its position directly below the filling mechanism and in order to move the cleaning cover away from its position directly below the filling mechanism.

[0056] The preferred embodiments and features of the present invention described above may be combined with each other as needed. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Figure 1 A device 10 for filling containers is shown. The device 10 can be included, for example, in a container processing plant. For example, the container processing plant can also have a device for sealing the filled containers. The device for sealing the filled containers can be connected to the device 10, for example, via a container conveyor.

[0070] Preferably, the device 10 can fill containers with liquid or pasty media. The device 10 is preferably embodied as a circular rotary filling device, for example with a vertical central rotation axis A. The device 10 can have several filling devices 12 for filling several containers simultaneously or overlapping in time. For example, the filling devices 12 can be arranged around the circumference of a filler turntable of the circular rotary filling device.

[0071] Figure 2 A section of a device 10 is shown, which has a filling device 12 (in Figure 2 ), a container holder 24, a cleaning cover 26 and a replacement system 30. Optionally, the device 10 may also have a lifting system 22.

[0072] Preferably, the device 10 has several stations, each with a filling mechanism 12, a container holder 24, a cleaning cover 26 and a replacement system 30, and optionally a lifting system 22. The stations can preferably be arranged distributed around the circumference of the device 10.

[0073] The filling mechanism 12 can be held at the rotatable upper part 14 of the device 10 (at Figure 2 The upper part 14 is preferably rotatable about a vertical central axis of rotation A of the device 10. For example, the upper part 14 can be rotated by a vertically oriented main axis / central axis of the device 10.

[0074] Preferably, the upper part 14 can be raised and lowered by means of a displacement device of the device 10. Possibly, the displacement device lowers the upper part 14 to a lower position or a lowermost position for the cleaning operation mode of the device 10.

[0075] The filling mechanism 12 can, for example, have a filling valve having a movable valve element for releasing and blocking a filling material path. Preferably, the filling mechanism 12 can also have a centering bell 16 and / or a filling level probe 20 .

[0076] The centering bell 16 can center the container to be filled directly below the filling device 12. For example, the centering bell 16 can have a conical receiving portion for the container mouth of the container. The receiving portion can be opened from the bottom side of the centering bell 16.

[0077] Preferably, the centering cover 16 can be vertically movable and guided. For example, the centering cover 16 can be vertically movable and guided by a vertical guide 18 (at Figure 2 The centering cover 16 is movable in a vertically guided manner (only schematically indicated in FIG. 1 ). It is feasible that the centering cover 16 is vertically movable relative to the filling material outlet or the filling valve housing of the filling mechanism 12. Correspondingly, the centering cover 16 can be lowered from a position close to the outlet or the filling valve housing and / or raised from a lowered position to be close to the filling material outlet or the filling valve housing.

[0078] The filling level probe 20 can protrude vertically downward from the filling mechanism 12. The filling level probe 20 can be immersed in the container when the container is filled by the filling mechanism 12. Preferably, the filling level probe 20 can send a filling stop signal to the filling mechanism 12 when the desired filling height is reached in the container. The filling level probe 20 can be implemented as a short-circuit probe, for example.

[0079] Preferably, the filling level probe 20 is an elongated, for example rod-shaped or tubular component. The longitudinal axis of the elongated filling level probe 20 may be oriented vertically. The filling level probe 20 may extend through the centering cap 16.

[0080] The lifting system 22 can lift and lower the container holder 24. Preferably, the lifting system 22 lifts and lowers the container holder 24 together with the cleaning cover 26 and the replacement system 30.

[0081] For example, the lifting system 22 can lift the container holder 24 together with the container carried by it for filling. During the lifting, the filling level probe 20 can be immersed in the container. During the lifting, the container mouth of the container can be in contact with the centering shield 16 or has been in contact with the centering shield. After filling, the lifting system 22 can lower the container holder 24 together with its filled container.

[0082] It is possible that the lifting system 22 lowers the container holder 24 , the cleaning cover 26 and the changing system 30 to a lower position or a lowermost position for the cleaning operating mode of the device 10 .

[0083] The container holder 24 can carry the container. The container holder can support the container when filling with the filling mechanism 12. Preferably, the container holder can support the bottom side of the container. For example, the container holder can be implemented as a container support plate. Alternatively or additionally, the container holder 24 can carry the circumference of the container, such as the container neck, container neck ring or container base (container body).

[0084] In the normal operating mode (filling operating mode) of the device 10, the container holder 24 can be positioned directly below the filling mechanism 12. As described in more detail herein, for the cleaning operating mode, the container holder 24 can be moved away from the position directly below the filling mechanism 12 by means of the replacement system 30 to create space for cleaning the cover 26.

[0085] The cleaning cover 26 can cover the filling mechanism 12 from below when cleaning the filling mechanism 12. Specifically, the filling mechanism 12 can cover the filling material outlet of the filling mechanism 12 from below. Therefore, the cleaning cover 26 can make the cleaning liquid flowing through the filling mechanism 12 flow back into the filling mechanism 12 at the filling material outlet of the filling mechanism 12 in the cleaning operation mode of the device 10.

[0086] Preferably, the cleaning cover 26 is embodied as a so-called CIP cleaning cover or clean-in-place cover.

[0087] Preferably, the cleaning cover 26 may be dimensioned to accommodate the filling level probe 20. For example, the cleaning cover may have an inner diameter that is greater than the outer diameter of the filling level probe 20. For example, the cleaning cover 26 may have a length that is greater than the length of the filling level probe 20.

[0088] For example, the fill level probe 20 may be substantially tubular, having a closed end and an oppositely arranged open end.

[0089] The cleaning cover 26 may, for example, have a cover opening 28. The cover opening 28 may, for example, be conical.

[0090] The outer shape of the cover opening 28 is preferably adapted to the inner shape of the centering cover 16. Preferably, the cleaning cover 26 can be inserted into the centering cover 16 through its cover opening 28. The centering cover 16 can hold or lock / fix the cleaning cover 26, for example, in the radial direction relative to the central vertical axis of the centering cover 16.

[0091] In the normal operating mode (filling operating mode) of the device 10, the cleaning cover 26 can be positioned away from the position directly below the filling mechanism 12, such as Figure 2 Preferably, the cleaning cover 26 can be oriented upside down in its non-use position, such as parallel to the vertical axis or at an angle less than 90° to the vertical axis (downward). As described in more detail herein, for the cleaning mode of operation, the cleaning cover 26 can be removed from the position directly below the filling mechanism 12 using the replacement system 30.

[0092] The replacement system 30 is usually designed to move the container holder 24 out of its position directly below the filling mechanism 12 and to move the cleaning cover 26 into its position directly below the filling mechanism 12 for cleaning the filling mechanism 12 .

[0093] In particular, the replacement system 30 can preferably move the container holder 24 between its position directly below the filling mechanism 12 (use position) and a non-use position of the container holder 24, which is laterally offset relative to the use position. Preferably, the replacement system 30 can pivot the container holder 24 from its position directly below the filling mechanism 12 to the side, for example about a pivot axis, preferably about a single and / or horizontal pivot axis, and / or to the non-use position.

[0094] In particular, the replacement system 30 can preferably move the cleaning cover 26 between its position (use position) directly below the filling mechanism 12 and a non-use position of the cleaning cover 26, which is laterally offset relative to the use position. Preferably, the replacement system 30 can pivot the cleaning cover 26 to its position directly below the filling mechanism 12, particularly preferably around several pivot axes spaced parallel to each other and / or from the non-use position.

[0095] Preferably, the direction in which the container holder 24 is pivoted away from its position directly below the filling mechanism 12 and the direction in which the cleaning cover 26 is pivoted to its position directly below the filling mechanism 12 coincide with each other.

[0096] Preferably, the non-use position of the container holder 24 and the non-use position of the cleaning cover 26 may be arranged on opposite sides of the replacement system 30 .

[0097] To complete the cleaning of the filling mechanism 12, the replacement system 30 can also move, preferably pivot, the container holder 24 back into its position directly below the filling mechanism 12, for example from its non-use position. In addition, the replacement system 30 can move, preferably pivot, the cleaning cover 26 away from its (use) position directly below the filling mechanism 12, for example into an inverted orientation of the cleaning cover 26 in its non-use position.

[0098] Preferably, the changing system 30 can have a lifting device 32 with a movable lifting element 34 and / or a pivoting device 38 .

[0099] The lifting device 32 may preferably be the sole drive source for movement of the container holder 24 from its position directly below the filling mechanism and also for movement of the cleaning cover 26 to its position directly below the filling structure 12 .

[0100] Preferably, the replacement system 30 couples the movement (e.g., moving away and / or moving to) of the container holder 24 and the movement (e.g., moving to and / or moving away) of the cleaning cover 26 to each other, particularly preferably mechanically. For example, a pivot device 38 connects the movable lifting element 34 to the container holder 24 and the cleaning cover 26.

[0101] As mentioned above, the lifting device 32 can have a movable lifting element 34. The lifting element 34 can be vertically telescopic. For example, the lifting element 34 can be implemented as a lifting piston. The lifting piston can be guided vertically movably, for example, in a (lifting) cylinder 36. The cylinder 36 and the lifting piston / lifting element 34 can form a piston-cylinder unit together. Preferably, the lifting device 32 can be a pneumatic lifting device, for example a single-acting or double-acting pneumatic piston-cylinder unit. Alternatively, the lifting device 32 can be, for example, a motor-type lifting device, an electric lifting device or a mechanical lifting device.

[0102] It is possible that the lifting element 34 is elastically preloaded for lowering, as here by reference to Figures 8 to 10 As exemplarily described.

[0103] The lifting device 32 can be arranged, for example, below the pivot device 38 and / or below the container holder 24 .

[0104] Preferably, the lifting device 32 can be connected to the lifting system 22 in a self-adjustable height manner. That is, the lifting system 22 can adjust the height of the lifting device 32 (and, for example, adjust the pivot device 38 connected thereto, the container support 24 connected thereto, and / or the cleaning cover 26 connected thereto).

[0105] The pivoting device 38 can, preferably under the drive of the lifting device 32, pivot the container holder 24 to its position directly below the filling mechanism 12 or pivot away from this position, and pivot the cleaning cover 26 to its position directly below the filling mechanism 12 or pivot away from this position, preferably in a mechanically coupled manner.

[0106] The pivot device 38 can be arranged, for example, between the container holder 24 and the lifting device 32. The pivot device 38 can have a housing 40 and a pivot mechanism arranged therein.

[0107] The following references Figures 3 to 6 A particularly preferred embodiment of the pivot device 38 is described.

[0108] The pivot device 38 can have a housing 40 and a pivot mechanism arranged therein. The pivot mechanism can, for example, have at least one lever element 42 (in Figure 3 is obscured in Figure 4 can be seen in Figure 5 and 6 Omitted), at least one guide curve portion 44 (in Figure 3 is obscured in Figure 4 , 5 and 6) and at least one pivot arm 48 (in Figure 3 is obscured in Figure 4 and 5can be seen in Figure 6 omitted).

[0109] Preferably, the pivot device 38 has two mirror-symmetrically arranged lever elements 42, two mirror-symmetrically arranged guide curves 44 and two mirror-symmetrically arranged pivot arms 48. Preferably, the mirror symmetry exists with respect to a vertical center plane of the pivot device 38. In the following, reference is made to only one of these elements, etc., in each case, in order to facilitate a better understanding.

[0110] The lever element 42 can guide a first end of the lever element 42 on a guide curve 44. For example, the lever element 42 can have a guide element 46, such as a guide pin, at its first end, which can engage in the guide curve 44.

[0111] The lever element 42 can be mounted on the container holder 24 at the second end of the lever element 42. For example, the lever element 42 can be fixedly mounted on the container holder 24 at its second end, for example by means of a screw connection.

[0112] The lever element 42 may be a double-sided lever. The lever element 42 may be pivotally connected to the movable lifting element 34 between its first end and second end. For example, the lever element 42 may be pivotally connected to the upper end of the movable lifting element 34. Preferably, the connection may be implemented as a horizontal pivot axis S1.

[0113] The lever element 42 may also be pivotally connected to the cleaning cover 26. For example, the lever element 42 may be pivotally connected to the lower end of the cleaning cover 26 (based on the upright orientation of the cleaning cover 26). Preferably, the connection may be implemented as a horizontal pivot axis S2.

[0114] Preferably, the lever element 42 may be implemented such that its three ends are substantially triangular.

[0115] The guide curve 44 is preferably arranged on the inner side of the housing 40. The guide curve 44 can be implemented, for example, as a guide curve groove.

[0116] The guide curve 44 can be fixed relative to the stationary part, preferably the cylinder 36 of the lifting device 32, for example by means of a screw connection.

[0117] Preferably, the guide curve 44 has a stepped shape. Specifically, the guide curve 44 may preferably have a substantially vertical first guide curve section 44A, a substantially inclined or horizontal second guide curve section 44B connected to the first guide curve section, and a substantially vertical third guide curve section 44C connected to the second guide curve section, optionally with a widened outlet end 45 (see Figure 6). The pivoting caused by this orientation will also be referred to in this article. Figure 7 Describe in more detail.

[0118] The guide curve 44 can also be referred to as a guide contour or a guide slot.

[0119] The pivot arm 48 can be pivotally connected to the movable lifting element 34 of the lifting device 32 at a first end of the pivot arm 48. For example, the pivot arm 48 can be pivotally connected to the upper end of the movable lifting element 34. Preferably, the connection can be implemented as a horizontal pivot axis S3. The pivot axis S3 can preferably be arranged above or below the pivot axis S1.

[0120] The pivot arm 48 can be pivotally connected to the cleaning cover 26 at the second end of the pivot arm 48. For example, the pivot arm 48 can be pivotally connected to the lower end of the cleaning cover 26 (based on the upright orientation of the cleaning cover 26). Preferably, the connection can be implemented as a horizontal pivot axis S4. The pivot axis S4 can preferably be arranged on the side next to the pivot axis S3.

[0121] Preferably, the lever element 42 and the pivot arm 48 can therefore be connected to the movable lifting element 34 via the pivot axes S1 and S3, and to the cleaning cover 26 via the pivot axes S2 and S4. Thus, the lever element 42 and the pivot arm 48 can jointly mechanically couple the movement of the container holder 24 and the movement of the cleaning cover 26.

[0122] The pivot axes S1 , S2 , S3 and / or S4 can, for example, be (each) embodied as a plain bearing (eg a plain bearing bushing) and as a pin, a shaft or a bolt which is rotatably supported in the plain bearing.

[0123] Preferably, the pivot axes S1 , S2 , S3 and / or S4 may be spaced apart and parallel to each other.

[0124] Preferably, an imaginary connection line (lever line) between the pivot axes S1 and S2 and an imaginary connection line (pivot arm line) between the pivot axes S3 and S4 may cross.

[0125] The following references Figure 7 The operation of the exemplary replacement system 30 to switch to the cleaning mode of operation of the device 10 is described in more detail. For a better understanding, Figure 7 The middle lifting device 32 is transparent, and the housing of the pivoting device 38 is open.

[0126] As in Figure 7 As can be seen in the first four figures, in a first section of the lift of the movable lifting element 34 , a pivoting of the container holder 24 from its position directly below the filling mechanism 12 and a pivoting of the cleaning cover 26 into its position directly below the filling mechanism 12 are effected.

[0127] In this case, the guide element 46 can follow the guide curve 44 .

[0128] In the (optional) first guide curve section 44A, the container holder 24 and the cleaning cover 26 can be lifted slightly.

[0129] In the second guide curve section 44B, this causes the container holder 24 to pivot from the position directly below the filling mechanism 12 and the cleaning cover 26 to pivot to its position directly below the filling mechanism 12. By means of the exemplary illustrated special configuration of the pivot device 38 with several pivot axes S1 to S4 etc., the angular range over which the cleaning cover 26 is pivoted to its position directly below the filling mechanism 12 (e.g. between 90° and 180°) can be greater than the angular range over which the container holder 24 is pivoted away from its position directly below the filling mechanism 12 (e.g. between 45° and 90°).

[0130] At the end of the second guide curve section 44B, the cleaning cover 26 may already be oriented upright and is preferably positioned directly below the lowered centering cover 16 .

[0131] In the third guide curve section 44A, the container holder 24 and the cleaning cover 26 can be further lifted. Here, the cover opening 28 of the cleaning cover 26 can be immersed in the lowered centering cover 16 and fit with its interior. At the end of the third guide curve section 44C, the cover opening 28 of the cleaning cover 26 can be positioned in the lowered centering cover 16.

[0132] exist Figure 7 As can be seen from the two figures at the bottom, in a second section of the stroke of the movable lifting element 34 , which follows the first section, a pure lifting movement of the container holder 24 and the cleaning cover 26 towards the filling device 12 can be effected.

[0133] The centering bell 16 guided by the vertical guide 18 can hereby assume the vertical guidance of the cleaning cover 26 toward the filling device 12. Preferably, the centering bell 16 can hereby be supported by the cleaning cover 26 so that it can also be lifted by the lifting device 32.

[0134] In the second section of the stroke, the fill level probe 20 can be immersed or inserted into the cleaning cover 26 .

[0135] Once the centering cup 16 is in sealing contact with the filling material outlet of the filling mechanism 12 , the delivery of the liquid cleaning agent can be started to perform CIP cleaning of the filling mechanism 12 .

[0136] At the end of the cleaning mode, the movement process described can be performed in reverse order.

[0137] Although the pivoting of the container holder 24 and the cleaning cover 26 disclosed here is particularly preferred, it is in principle possible to configure the exchange system 30 in another way, for example for a lateral displacement of the container holder 24 and / or the cleaning cover 26 .

[0138] Figures 8 to 10 A modified device 10 ′ (or portion thereof) having an exemplary lifting device 32 and locking device 54 is shown.

[0139] It is understood that the locking device 54 is also generally disclosed herein and may, for example, be included in reference Figures 2 to 7 In the exemplary device 10 described.

[0140] The lifting device 32 can preferably be embodied as a mechanical lifting device.

[0141] For example, the lifting device 32 may have a lifting curve follower 50. The lifting curve follower 50 may follow a fixed lifting curve portion (in Figures 8 to 10 For example, the lifting curve follower 50 can be implemented as a roller, such as Figure 8 As shown in . The lift curve follower 50 implemented as a roller can roll at (eg on) the lift curve portion.

[0142] The lifting curve follower 50 may be operatively connected to the lifting element 34 so as to vertically move the lifting element 34. For example, the lifting curve follower 50 may be arranged at the lower end of the lifting element 34. The lifting curve follower 50 may, for example, be rotatably supported at the lower end of the lifting element 34. The lifting curve follower 50 may transmit the height profile of the lifting curve portion to the lifting element 34.

[0143] Preferably, the lifting curve follower 50 can lift the lifting element 34 according to the height profile of the lifting curve portion. This can move the cleaning cover 26 to its position directly below the filling mechanism 12 (see, for example, Figure 2 ), and the container holder 24 can be moved away from its position directly below the filling mechanism 12 (see, for example Figure 2 ).

[0144] For example, if the lifting element 34 and its associated lifting curve follower 50 are moved to the lowest position and the device 10' is rotated (see Figure 1 ), the lifting curve follower 50 can abut against the lifting curve portion, for example sit on it. Then, in the rotation direction of the device 10 ′, the lifting curve portion can use the lifting curve follower 50 to lift the lifting element 34, for example against the elastic preload of the lifting element 34.

[0145] It is possible that the lifting element 34 is elastically preloaded for lowering.

[0146] For example, the lifting element 52 may be elastically preloaded by the elastic element 34 to be lowered. The elastic element 52 may, for example, be arranged between the lifting element 34 and the cylinder 36. Preferably, the elastic element 52 may be arranged in the cylinder 36.

[0147] For example, the elastic element 52 can be implemented as a (compression) spring, preferably a coil spring. The coil spring can be arranged coaxially with the lifting element 34. Preferably, the coil spring is arranged between the outer circumference of the lifting element 34 and the inner circumference of the cylinder 36.

[0148] By means of the elastic element 52, the cleaning cover 26 can be moved away from its position directly below the filling mechanism 12 after use of the cleaning cover 26, for example after CIP cleaning (see Figure 2 ), and the container holder 24 can be moved into its position directly below the filling mechanism 12 (see Figure 2 ).

[0149] Purely by way of example, Figure 8 It is also shown that the cleaning cover 26 has an inverted orientation or is oriented downwards in its non-use position, wherein the longitudinal axis of the cleaning cover 26 forms an angle of <90°, preferably ≤45° or ≤25° with the vertical axis.

[0150] The locking device 54 may be configured to lock the lifting element 34 in a position in which the cleaning cover 26 is positioned in its position directly below the filling mechanism 12. Preferably, the locking device 54 is a mechanical locking device.

[0151] For example, Figure 8 and Fig. 9 The locking device 54 is shown in an unlocked or released position. Fig.10 The locking device 54 is shown in the locked position.

[0152] The locking device 54 can have a (e.g. horizontally) movable locking element 56. The locking element 56 can be locked in order to lock the lifting element 34 in a raised position of the lifting element 34, for example when the cleaning cover 26 is positioned in its position directly below the filling mechanism 12. The locking element 56 can be, for example, a plate or a (e.g. metal) block.

[0153] Preferably, the locking element 56 can lock the lifting element 34 at the boss (or shoulder) 58 of the lifting element 34. The locking element 56 can act as a stop for the boss 58. In the locked position, the boss 58 and the locking element 56 can contact each other (see Fig.10 In the release position, the boss 58 and the locking element 56 may be spaced apart from each other (see Figure 8 and Fig. 9 ).

[0154] For example, the lifting element 34 can have two elongated piston parts. The two piston parts can be arranged offset from each other in the horizontal and vertical directions. The two piston parts of the lifting element 38 can be connected to each other via a boss 58. For example, the lifting element 34 can be implemented in a stepped manner with a boss 58 between the two piston parts. The lifting element 34 is preferably multi-piece and has two piston parts, which are connected to each other via a connecting part with a boss 58 and fixed to each other.

[0155] Alternatively, the lifting element 34 may for example be constructed as a (single) continuous piston rod.The boss 58 may preferably be formed as a part in the piston rod, for example a groove, a hole or a bore.

[0156] Preferably, the locking element 56 can be elastically preloaded to occupy the locking position. For example, an elastic element 60, such as a (eg, helical and / or compression) spring, can elastically preload the locking element 56 to occupy the locking position.

[0157] For example, one end of the elastic element 60 can be accommodated in the carrier 62. The opposite end of the elastic element 60 can be connected to the locking element 56, for example, to support the locking element. The carrier 62 can be installed at the cylinder 36, for example. The longitudinal axis of the elastic element 60 can preferably extend horizontally.

[0158] The lifting element 34 can slide along the end surface of the locking element 56. Once the lifting element 34 has reached the lifting position (e.g. caused by the lifting curve follower 50 and the lifting curve), the boss 58 may have passed the locking element 56. Then, the upper edge of the locking element 56 can be positioned below the boss 58. The locking element 56 can then move under the boss 58 (e.g. caused by the elastic element 60) to occupy the locking position and thus lock the lifting element 34 in the lifting position. Correspondingly, the cleaning cover 26 can be locked in its position directly below the filling mechanism 12 (see Figure 2 ).

[0159] Various techniques are conceivable for releasing the locking device 54 . For example, the locking device 54 may be mechanically actuatable to release the lifting element 34 .

[0160] The locking device 54 may, for example, have a movable unlocking element 64, such as a pressure plate. The unlocking element 64 may be operatively connected to the locking element 56 so as to move the locking element 56 away from the locked position.

[0161] For example, the unlocking element 64 and the locking element 56 may be arranged on opposite circumferential sides of the lifting element 34. The operative connection between the unlocking element 64 and the locking element 56 may be configured, for example, via a clip-shaped or fork-shaped connection that bypasses the lifting element 34.

[0162] The movement of the unlocking element 64 in the direction of the carrier 62 can remove the locking element 56 so that it is no longer in contact with the boss 58, until the lifting element 34 can pass the retracted locking element 56 again to be lowered (for example under the action of the elastic element 52). The force applied by the unlocking element 64 can preferably overcome the elastic preload of the elastic element 60 on the locking element 56.

[0163] For example, the unlocking element 64 can be movable by a fixed (e.g., pneumatic or electric) actuator (not shown). The actuator can, for example, retract and extend a control element (e.g., a control curve or a roller). In the extended or retracted state of the actuator, when rotating the device 10 ′, the unlocking element 64 can run along the control element and can be pushed away from the control element to move the locking element 56 so as to release the lifting element 34.

[0164] The invention is not limited to the preferred embodiments described above. On the contrary, a large number of variants and variations are possible, which also utilize the concept of the invention and therefore fall within the scope of protection. In particular, the invention also claims the subject matter and features of the dependent claims independent of the cited claims. In particular, the individual features of independent claim 1 are disclosed independently of each other. In addition, the features of the dependent claims are disclosed independent of all the features of independent claim 1, as well as features such as the presence and / or configuration of the filling mechanism, container holder, cleaning cover and / or replacement system independent of independent claim 1. All range descriptions provided herein are to be understood as disclosed, i.e. all values ​​falling within the respective ranges appear to be disclosed individually, for example, preferably also as narrower outer boundaries of the respective ranges.
