Description

The invention relates to a container treatment machine specified in the preamble of claim 1. Art Such a container treatment machine in the manner of a filling machine is from the document DE 10 2007 035 872 A1 known. In this Behätterfüllmaschine for the return gas pipe of a filling valve, a positioning device is provided with a linear electric motor, the stator arranged fixedly arranged cooperates with a arranged on the return gas axial runner to set different positions of the return gas pipe and set. A conversion of the return gas pipe from one position to another requires a current application of the linear motor. An axial magnetic interaction is generated between the stator part and the axial rotor. The return gas pipe carries no flow guide.

Medium-carrying tubes are used in different container treatment machines for the respective processes for different purposes each at a predetermined holding position and must be replaced or adjusted in a variety change in the rule. Such media-carrying pipes require, for example, filler (carousel machine or rotary), cleaning machines (rinser, bottle washing machine) or sterilization machines (preheater, sterilizer, radiator).

Out DE 1 254 498 B a filling valve of a filler is known which is equipped with a return gas pipe as the media-carrying pipe and with at least one deflector screen on the return gas pipe. At the upper end of the return gas pipe, a plurality of circumferential grooves are arranged in different axial regions, which serve in the filling valve for the positive locking engagement of the return gas pipe at different height positions. Furthermore, two further circumferential grooves are formed on the outside of the return gas pipe, which define different, optionally usable holding positions for a deflected shield there. The grooves and the catches result in hygienic problems.

Out DE 20 2006 019 136 U is a sterilizer known here for bottle sterilization, which has a treatment tube in a treatment station as the media-carrying tube, which is optionally adjustable in the longitudinal direction. On the treatment tube sits as Strömungsleitkörper a Umlenkkalotte.

At one off FR 1 246 555 A known, designed as a filler container treatment machine, a magnetic drive for controlling relative movements between two coaxial tubes is provided. The magnetic drive comprises a magnet, a magnetic plate and an axially movable armature. By means of the magnet, which is subjected to different currents to produce different magnetic flux densities, not only a valve formed between the tubes is opened and closed, but both tubes are also adjusted in height together. The exterior of the tubes carries a flow guide which is anchored to this tube at a fixed position.

At one off JP 2000 185796 A known container treatment machine carries the return gas pipe of a filling valve at a fixed axial region a support member which magnetically cooperates with a height-adjustable outside of an encapsulation magnetic ring to change the height position of the return gas pipe. To adjust the height of the outer magnet ring an externally driven actuator is provided.

Out US 3,455,350 A a container treatment machine is known in which in the filling valve is provided from the valve member downwardly extending tube with a flow guide. In different embodiments shown different tubes with different, each firmly mounted flow guide bodies are disclosed.

Carbonated drinks are bottled by constant pressure filling. The mouth of the container, eg a bottle, is sealingly pressed against a filling element to produce (bias) a higher filling pressure than the ambient pressure, from a pressurized gas reservoir. After a filling process, the overpressure is reduced, for example via a return gas channel and a return gas pipe. As a rule, carbonated drinks are not filled with full jet onto the bottom of the container, but rather along the inner wall of the container and are deflected towards the inner wall. For this serves as at least one flow guide arranged on the outside of the return gas tube Abweiseschirm which projects in the axial direction of the filler or container by a certain extent in this and thus is at a required location in the container, but must be fixed in a predetermined holding position on the return gas pipe , For bottlenecks of different width, deflector screens with different diameters and / or pitches are required. Depending on the product, deflector screens made of different materials or in different thicknesses may be required. The one or more Abweiseschirme are usually arranged in their holding position firmly on the return gas pipe. Since the immersion depth of the return gas tube adjusts the filling level, either the return gas tubes are exchangeable at a predetermined holding position in one for grade change Filling plug inserted or is the return gas pipe or its holding position manually or automatically adjustable by actuators. Depending on the geometry of the container mouth and the neck, the required location of the deflector shield varies in the container, so that the beverage is filled as gently as possible. If the return gas pipe is adjusted in the longitudinal direction, consequently, the deflector screen is no longer placed at the required location in the container. The described problem also occurs in so-called vacuum filling machines, in which the filling level in the container is adjusted by applying a negative pressure, wherein overfilled filling product is sucked out of the container again through the return gas pipe.

Also in the cleaning or sterilization of containers (bottles or preforms), depending on the variety, a treatment tube with its tube end is immersed deeper or less deeply, which is accomplished by adjusting or swapping the treatment tube. In most cases, no flow guide body is arranged here on the treatment tube, although a deflection calotte can nevertheless be placed on the treatment tube in order to sterilize a threaded region.

The invention has for its object to improve a container treatment machine of the type mentioned in terms of hygienic maintenance of the media-carrying tube and optionally a flow on the pipe, and to allow easy and quick change in a container variety or filling product change.

The stated object is achieved with the features of claim 1.

Since the respective holding position for the media-carrying pipe and / or the flow guide is defined by magnetic forces, eliminates due to the very smooth or covered arranged magnet holder deposits favoring or difficult to clean undercuts in the holding position. This eliminates hygienic problems. Furthermore, the holding position can be solved easily and quickly, either to perform an exchange or to set another holding position, if more than one defined holding position is provided. If a magnetic holder is provided for each of the flow guide body and the media-carrying tube, both components can easily be exchanged or can easily and quickly set a new optimum holding position of the flow guide body when setting a new holding position of the media-carrying tube. In this case, in the respective magnet holder on at least one axial region at least one holding element consisting of a full-circumference ring or at least one partially circumferential ring segment made of permanently magnetic or magnetizable material is provided on or in the medium-carrying tube, and at least one axial region on or in a pipe wall receiving the channel or flow guide inner wall at least one consisting of a full ring or at least a teilumfbaren ring segment of permanent magnetic or magnetic material support member provided, wherein the respective support member of the pipe and the channel wall or the Flow guide inner wall have opposite polarizations and are aligned in the respective holding position radially to the axial direction and radially attract. Depending on the use of a full-circumference ring or at least a teilumfbaren ring segment a full holding power between the support members is generated by magnetic means, or only at least one local location or a peripheral portion, the respective holding position is defined properly and reproducible.

In an expedient embodiment, therefore, the respective magnetic holder is formed either to adjust the depth of immersion of the pipe end in the mouth of the container and / or the Strömungsleitkörpers along the tube with at least two selectively usable axially offset holding positions. The changeover can be carried out quickly and easily either manually or via actuator drives.

In an expedient embodiment, the media-carrying tube is a return gas tube in a filling valve sleeve of a pressure filling valve. The return gas pipe is held hygienically with the magnetic holder, and easily and quickly either exchangeable or convertible. The flow guide body can, preferably, be at least one deflector screen, which is likewise fixed to a magnet holder on the return gas tube at at least one holding position. If the return gas pipe is moved longitudinally to a new holding position, the deflector screen can be easily and quickly brought back to an optimum holding position and fixed or exchanged. The respective magnetic holder is hygienic, stable and structurally simple.

In another expedient embodiment, the media-carrying tube is a treatment tube in a valve head of a rinsing, washing or sterilizing station. Thanks to the magnetic holder, the treatment tube can either be easily and quickly replaced or adjusted to a new holding position. If, as for example in a sterilizer, a flow-guiding body should be arranged on the outside of the treatment tube, this can be a sterilization-deflecting calotte which, thanks to its magnetic holder, can be exchanged and / or adjusted quickly and easily.

In a further embodiment, several teilumfängliche ring segments of a support member in the circumferential direction have the same polarizations, or alternately opposite polarizations. In this case, only two teilumfängliche ring segments can be used to generate the holding force and defining the holding position, which attract each other.

If several full-length rings or teilumfängliche ring segments should be provided inside and / or outside, they may have alternating polarizations in the axial direction, for example, to avoid that the deflector screen accidentally engages in an adjacent holding position and not properly in the next but one. Incidentally, two or more holding elements may be provided inside and outside for each holding position, in order to increase the holding force and to better define the holding position.

In an advantageous embodiment, a plurality of axially distributed on the pipe and / or the channel wall or flow guide inner wall provided support members are each provided with each other with the same or alternately opposite polarizations.

The respective support element, for example the full-circumference ring or the partially circumferential ring segment, is expediently fixed in a circumferential groove, e.g. pressed, glued, potted, or welded, or poured into the material of the tube, the flow guide or the channel wall. This fixation can be hygienically formed properly, i. non-depositable and difficult to clean undercuts, e.g. such that the support member is placed below the continuous surface.

Suitably, the material of the tube, the channel wall or the flow guide is non-magnetic, so as not to disturb or distort the magnetic forces for defining the holding position.

As mentioned, a plurality of axially spaced inner and outer support members may be aligned and tightened at the same time in the respective holding position.

In a further embodiment, identical or different axial distances are provided between more than two holding positions. The distances can be matched to the container portfolio to be processed in the container treatment machine.

In a further expedient embodiment, an outwardly projecting Abgleitsicherung is provided in the direction of or at the pipe end of the media-carrying pipe outside, expedient if on the pipe, a flow guide should be interchangeable and / or arranged. The flow guide could be uncontrollably displaced from its holding position, for example, in a cleaning cycle due to very high flow rates, or in the bottling by erroneous contact with the mouth and then stripped from the tube and washed away. This Abgleitsicherung is, preferably, an annular flange, a flange segment, at least one nose or pin, a compression, a bend or the like .. The cross section of this Abgleitsicherung can be chosen arbitrarily. The Abgleitsicherung can also be made by upsetting the pipe end, by machining, punching, rolling, bending, or applied as a separate component and permanently fixed. The material of the Abgleitsicherung does not necessarily have to be equal to the material of the pipe or flow guide. The Abgleitsicherung could also be fixed by gluing, soldering, welding, clamps, etc. The anti-unloading device only has to ensure that it takes up a width that is greater than the inside width of the inner wall of the flow guide.

In a further advantageous embodiment, the at least one exchangeable and / or adjustable flow guide carrying, media-carrying tube extending from the respective holding position for the flow guide to the pipe end and / or to an opposite pipe end with an outer width at most corresponding to the inner width of the flow guide inner wall. As a result, the replacement of the flow guide, for example, the Abweiseschirms, simplified. For this purpose, only the media-carrying pipe needs to be pulled out by releasing its magnetic holder, before the flow guide body, which is likewise fixed by its magnetic mount, can be removed and exchanged.

In Fig. 1 is shown in a section of the internal structure of an example designed as a filling valve outlet and / or inlet element V of a container treatment machine, not shown, as a non-limiting example. The container treatment machine may according to Fig. 1 be a filler, or (not shown) a dishwasher, washing machine, or a sterilizer for bottles or preforms. Regardless of the type of container treatment machine, a media-carrying tube R is provided in the outlet and / or inlet element V, which is fixed at least interchangeably at a predetermined holding position P1 and in an in Fig. 1 not shown container immersed in the mouth.

The concept according to the invention of at least one detachable magnetic mount M1, here for the media-carrying pipe R, will be described on the basis of the non-limiting example of the filling valve of a container treatment machine designed as a filler, as in FIG Fig. 1 shown, explained.

The filling valve includes a valve sleeve 1, in the interior of which a return gas channel 3 extends, and which has a conical seat surface 2 at the lower end. In the upper end of the valve sleeve 1, an adjustable return gas needle 4 is shown in an extension. The media-carrying pipe R is a return gas pipe 5 and inserted with an attached or integral thickening 6 in the lower open end of the valve sleeve 1 and there at the holding position P1 by means of the releasable Magnetic holder M1 fixed. Preferably, the tube R and the valve sleeve 1, at least in its lower portion, made of non-magnetic material. To define the holding position P1 by magnetic forces here are an outer, full-circumference and annular outer support member Ha and also a full, annular inner support member Hi provided that either permanent magnetic or magnetizable and magnetized material and have different polarizations, such that they attract each other , The outer support member Ha is set, for example in a circumferential groove in the outer periphery of the valve sleeve 1, for example, pressed, glued, welded, soldered, cast, or even poured into its material and encapsulated on all sides. The inner support member Hi is also here in an outer circumferential groove of the media-carrying tube, ie the return gas tube 5, or in its thickening 6 set analog or encapsulated encapsulated on all sides. An elastic seal 11, for example an O-ring, of the return gas pipe 5 seals in the holding position P1. The inner support element Hi is, for example, an annular body 10 (magnetic ring), just as the outer support element Ha is an annular body 9 (magnetic ring). The mutually cooperating support elements Ha, Hi could also be formed only by a respective teilumfängliches annular segment (not shown), or by a plurality of circumferentially distributed teilumfängliche ring segments (not shown). To replace the return gas pipe 5 this is, for example, manually pulled out by loosening the magnetic mount M1 in the axial direction Y and replaced by another, after a change of grade of a container to be filled or a product change suitable return gas pipe 5, which in turn in the magnetic holder M1 at the holding position P1 is set and then optionally immersed with another immersion depth of the lower pipe end 7 in the mouth of the container.

As may be appropriate for Gleichdruckfüllverfahren is on the return gas pipe 5 in Fig. 1 At least one flow guide K arranged at a predetermined position, for example, firmly connected to the return gas pipe 5. Alternatively, the flow guide K, here a deflector 8, be determined by means of a detachable, further magnet holder M2. In a further, not shown alternative, the media-carrying pipe R is set in a conventional manner by other means at the holding position P1 interchangeable, and only the flow guide K with its magnetic holder M2 (analogous to the magnetic holder M1) determined as Fig. 3 to 8 will be explained.

Fig. 2 clarifies a detail variant too Fig. 1 and shows the left half of the partial axis section showing the magnetic holder M1 for the media-carrying pipe R, here the return gas pipe 5, in the valve sleeve 1. In Fig. 2 For example, in the valve sleeve 1 more embedded outer support members Ha arranged distributed in the axial direction, which optionally with only an inner support member Hi of the return gas pipe 5 cooperate to generate magnetic forces due to opposite polarizations, which can set different holding positions P1 to Pn. The axial distances between the different holding positions P1 to Pn may be equal to each other or, as indicated by x1 and x2, different from each other. The magnetic mount M1 serves not only to set the return gas pipe 5 at the predetermined holding position P1, but allows the setting of different holding positions P1 to Pn to set with a return gas pipe 5 more container filling heights can. The respective magnetic holder M1 (as well as M2) works with magnetic forces (forces of attraction) and is wear-resistant or wear-free and from a microbiological point of view optimal (hygienic), and easy to clean. In the Fig. 2 For example, each annular body 9a, 9b, 9c of permanently magnetic or magnetizable and magnetized material shown outer support members Ha. Although in Fig. 2 Only an inner support body Hi is shown, alternatively, several such inner support body Hi may be provided in the axial direction, so that at the respective holding position P1 to Pn at least two inner and two outer support body Hi, Ha cooperate.

Furthermore, only an outer holder body Ha as in Fig. 1 be provided, and for setting different holding positions more distributed in the return gas pipe 5 in the axial direction arranged inner support body Hi.

Fig. 3 shows an embodiment of a media-carrying pipe R, for example, a return gas pipe 5, with a flow guide K arranged thereon, eg a deflector screen 8. However, the media-carrying pipe R and the flow guide K could also be a treatment tube and a Umlenkkalotte another type of container treatment machine.

In Fig. 3 are in the media-carrying pipe R, eg the return gas pipe 5, placed at three different axial areas in each case an annular body 13, 13a, 13b as part of the magnetic holder M2, have the same polarizations, wherein the axial distance between the annular bodies 13 and 13a is shorter than for example between 13a and 13b. In the deflector screen 8, however, a single annular body 12 is provided, which optionally interacts magnetically with each of the annular body 13, 13a and 13b to define a plurality of holding positions P1, P2, P3 for the deflector screen 8 here.

As a detail variant is further in Fig. 3 in the direction of or at the lower end of the pipe 7 a Abgleitsicherung S provided which projects outward and claimed a width that is less than the inner width of the Abweiseschirmes 8. The Abgleitsicherung S is for example a Flange 14 or a flange segment, a nose or a pin or a compression or bending or the like., And can either be formed from the material of the tube R or placed and fixed as a separate body. The Abgleitsicherung S ensures that brought in the process of accidentally brought out of the hold position Abweiseschirm 8 does not slide off and falls.

In the embodiment in FIG Fig. 4 are in the return gas pipe 5 for defining two holding positions P1, P2 in the magnet holder M2 each three ring body 13 axially close to each other and placed with the same intermediate distances. In the flow guide K, here the deflector screen 8, however, three ring body 12 are arranged opposite to the polarizations of the ring body 13 polarizations (indicated by a cross) with the same intermediate distances as the ring body 13. The holding position P1 is, for example, further spaced from the holding position P2, as the axial extent, which is occupied by the three annular bodies 13.

In the embodiment in FIG Fig. 4 the two very stable holding positions P1, P2 are each defined by the fact that all three annular bodies 13 and 12 are radially aligned. However, it is also possible to set intermediate holding positions, in which only two inner and two outer or one inner and one outer annular body 12, 13 are radially aligned with each other. However, these intermediate stop positions do not provide the full holding force given in the stop positions P1 and P2.

In the embodiment in FIG Fig. 5 are in the return gas pipe 5 a total of six annular body 13, for example, distributed in equal axial distances, while in the deflector screen 8 as part of the magnetic holder M2 two annular body 12 are provided, between which the distance corresponds to the distance of the annular body 13. The annular bodies 13 are alternately polarized in the axial direction in opposite directions, as indicated by a blackening and a cross. The annular bodies 12 are polarized opposite (blackened or crossed), but inversely as the ring body 13. In this way, three holding positions are defined in which two inner and two outer ring body 12, 13 are radially aligned and attract each other. For only one pitch offset intermediate positions are not possible here.

In the in 6 and 7 indicated embodiment, the annular body 12, 13 are not full, but is each inner and / or outer support member Hi, Ha by at least one teilumfängliches annular segment 15, 16, 17, 18 ( Fig. 7 ) Are defined. In the embodiment of 6 and 7 are two approximately 180 ° circumferentially offset from each other ring segments 15, 16, 17, 18 are provided, although in each case only a single ring segment would be sufficient, or are provided in the circumferential direction more than two teilumfängliche segments. For defining two holding positions P1, P2 are in the return gas tube 5 axially relatively widely spaced two annular bodies 13 are provided which have opposite polarizations (crossed and blackened), while in Abweiseschirm 8 only two ring body 12 also with opposite polarizations and an intermediate distance corresponding to the distance between two of the annular body 13 are provided. As indicated by crossing and blackening, the part-circumferential ring segments 15, 16, 17, 18 ( Fig. 7 ) even with circumferentially alternating polarizations. This does not exclude, by partially umfängängliche ring segments 15, 16, 17, 18 defined annular body 12, 13 also form with the same polarization in the circumferential direction of the partially circumferential ring segments. This arrangement avoids that an intermediate holding position with respect to the holding positions P1 and P2 can be set accidentally or intentionally with only one pitch at a time. When adjusting the Abweiseschirmes 8 in the axial direction of the holding position P1 to P2 or vice versa care must be taken to obtain the correct rotational position of the Abweiseschirmes so that the attracting ring segments are also properly aligned radially to each other.

In the embodiment in FIG Fig. 8 are in the return gas pipe R a total of, for example, eight equally spaced axial spaced annular body 13 with axially alternately opposing polarizations arranged, defining a plurality of holding positions P1 to Pn. In Abweiseschirm 8 two axially spaced at the same pitch annular body 12 are also provided with opposite polarizations. The annular body 12, 13 are, for example, of teilumfbaren ring segments 15, 16, 17, 18, analogous to Fig. 7 , Defined, for example, each offset by 180 ° in the circumferential direction to each other. Here, a total of seven different holding positions P1 to Pn can be set for the deflector screen 8 on the return gas pipe 5, namely four holding positions axially spaced apart by two pitches, and three further holding positions spaced by one pitch. Such a holding position spaced apart by only one pitch is indicated at Pn for the deflecting screen 8 axially adjusted in the direction of the dashed arrow 21, whereby, however, the deflecting screen 8 corresponding to the arrow 20 has to be turned by 180 ° in order to set this stop position offset by only one pitch. By axial adjustment in the direction of arrow 21 and alternately back and forth rotation in the direction of arrow 20 here a relatively large adjustment is possible with defined holding positions, each two inner ring body 13 and two outer ring body 12 are radially aligned and jointly generate the holding force ,
