Description

Method and device for the combined production and filling of plastic containers

The invention relates to a method and apparatus for the combined production and filling of containers made of plastic, in particular plastic bottles, after which the respective container is produced by a thermal molding process, then transferred to a filling device and cooled during this transfer, and then the container is finally filled in the filling device with a product medium.

Such a method has become known by and large by DE 43 26 601 A1. In addition to the essay "From the blow molding machine directly into the pen" of the authors. Sven Fischer and Dr. med. Christian Detrois of the company Krones AG referenced (company magazine 3-2002, page 105 ff.). In the context of the latter publication, it is described how PET bottles produced with the aid of a blow molding machine are cooled and stabilized as soon as possible after their production by cooling measures so that they can be filled with the product medium immediately afterwards in the filling device. This is in the example case, a CO 2 -containing product, which under

Preload is bottled, thus increased demands on the mechanical stability of the previously directly produced PET bottle.

[0003] In order to achieve this stability, the bottles are sprayed from outside with cooled water within the scope of the known procedure. This is disadvantageous, as this results in an increased water requirement or the running water must be elaborately treated if it is to be recycled. This results in not inconsiderable costs.

Quite independently, it is known in the production of hollow bodies made of thermoplastic material in a contoured blow mold from practice to cool the hollow body, in which a cooling medium is blown into the interior. Another possibility of cooling is described in DE 10 2004 023 419 A1, in which the plastic bottles produced for active cooling pass through a cooling tunnel which at least partially cools the bottles. - The procedures described for cooling are relatively expensive and energy-intensive. Here, the invention aims to provide a total remedy.

[0006] The technical problem underlying the invention is to further develop a method and a device of the embodiment described above in such a way that the energy efficiency is increased and the costs in carrying out the method are reduced.

To solve this technical problem, the invention proposes in a generic method, that the container produced in each case during its transfer (after the thermal molding process) is cooled by applying a spray. It is understood that the cooling is carried out or carried out so much that can be filled and cooled container immediately after in the filling with the desired product medium. These are not limited to CO2-containing products that are filled under bias, so require immediately available sufficient stability of the plastic containers or plastic bottles produced, so they do not burst during filling or otherwise damaged.

It has proved to be particularly advantageous if the production of the container in the thermal molding process and its filling connect directly to each other, so a combined production and filling takes place by both associated devices ultimately form a structural unit. In this case, the containers are passed between a blow molding machine for their manufacture by the thermal forming process and the filling device through a transfer line, which is an integral part of this assembly. As a result, a space-saving and cost-effective design is provided and unnecessary any cleaning procedures, which then required are when a longer transport path or even a storage of the produced containers after their production and before filling is required.

By the immediate cooling of the container following its production by means of the spray according to the invention during its transfer is now achieved according to the invention that the container immediately upon entry into the

Filling device are cooled at least so far that they can be filled with virtually any conceivable product medium, including with carbonated beverages.

Ie. the bottles or containers are in ready to use state when entering the filling device.

It has proven particularly useful if the spray applied only selected areas of the container. Because the spray is distributed during operation often and in no time within the entire filling device and / or the transfer line. As a consequence of this, penetration into, for example, a bottle opening must be prevented in order to prevent mixing of the spray with the product medium to be subsequently introduced. That is, the container is generally divided on its outer surface and, according to an advantageous embodiment, into a spray-mist-free region and a spray-sprayed region. Of course, a plurality of spray-mist-free areas and spray-affected areas on the outer surface of the container can be realized.

In order to realize the separation into the spray-fog-free area and the area subject to spray on the outer surface of the container in detail, means are regularly provided for guiding and / or limiting the spray. These means can be a liquid atomizing device and a compressed gas unit in the context of a spray misting machine. Because in this way, the atomized liquid can be applied with a targeted jet and under pressure to the respective container. For this purpose, an outlet pipe with an outlet nozzle at the end of the spray mist machine may additionally contribute, which ultimately ensure that the In fact, mist only precipitates on the desired spray-misted area of the container and otherwise the spray-mist-free area of the container remains unaffected.

Alternatively or additionally, the means for guiding and / or limiting the spray mist may also be a shut-off device which seals off the spray-mist machine from spray-cloud-free areas of the container. In this case, it is ensured, as it were by mechanical means, that the container is divided on its outer surface into the spray-misted area and the spray-mist-free area. Actually, this is ensured by the shut-off device. In the simplest case, this may seal off the spray misting machine in the form of a shut-off plate or a shut-off plate, the containers being guided only through a slot in the shut-off device. The outer surfaces of the respective container, which are located in the area of the sprayer machine, are supplied with the spray mist and define the sprayed area of the container. On the other hand, beyond the shut-off device, no action is taken on the spray, so that the spray-mist-free region of the associated container automatically adjusts there.

As a further possibility for the realization of a means for the guidance and / or limitation of the spray, the invention proposes a gas flow device. This gas flow device generates a preferably sterile gas flow or else air flow, which acts on the spray-mist-free regions of the container in order to keep the spray out. In this case, therefore, a shut-off device is not necessarily required. Likewise, it does not matter if the spray directed or undirected applied to the container. Because the gas flow leaving the gas flow device ensures that the spray-mist-free region of the container is acted upon here or is guided through a corresponding gas stream curtain, so that spray mist can not be precipitated onto the container at this point. According to an advantageous embodiment of the invention, the above-described means can be optionally combined with each other. D. h., The atomizing device including compressed gas unit, outlet pipe and outlet nozzle of the spray mist machine can be combined with the shut-off device described and / or the gas flow device. Just as well, the shut-off device and the gas flow device can be realized simultaneously or the gas flow device and the atomizing device including compressed gas unit, outlet tube and outlet nozzle. Of course, all three measures described can also be combined in order to achieve a particularly effective separation between the respectively spray-mist-free and spray-misted area of the container and in particular to ensure that no spray can reach the interior of the container.

It has been proven in summary, when the spray is applied to the container at least in areas of high material thickness, for example in the bottom area. That is to say, the bottom region virtually coincides with the area of the container subject to the spray mist, whereas the mouth region and in most cases also the jacket region of the container represent the spray-fog-free region. By this measure, the invention takes into account the fact that the addressed areas of high material thickness must be particularly cooled, because by a local accumulation of the plastic and due to its poor heat conduction temperature peaks are otherwise observed in these areas that do not allow an immediately subsequent filling.

In any case, it is recommended, especially the areas of high material thickness to cool targeted, whereas the other areas of the container are mostly cooled by the transfer as such, namely by direct heat radiation or as a result of convection with the ambient air. - The areas of high material thickness are not limited to the floor area. However, it is also possible for the mouth region of the container or the plastic bottle in particular to undergo the described treatment. In general, the spray is composed of a gas and a finely atomized liquid therein. The gas is usually air. In the generally pressurized air, the liquid, such as water, is now finely atomized into droplets. The existing liquid in the spray can now be used advantageously for evaporative cooling of the container. The required compressed air is usually available anyway, so that expensive installation work is not required.

In fact, the finely atomized droplets from the liquid as a result of their transport with the compressed air after their application to the container a (thin) liquid film. This liquid film evaporates because the container as a carrier has an elevated temperature. At the same time the container cools down.

For example, at the entrance of the transfer line and immediately after the blow molding machine temperatures for the plastic containers produced in the range of more than 70 ° C are observed. These temperatures can be up to 90 ° C or even higher. Now, if a thin liquid film of water is applied to such a container, the temperature of the container immediately ensures that the liquid film evaporates. As a result, the container cools primarily in the areas where the liquid film is present (evaporative cooling). Due to the temperature conditions, it is also clear that water is particularly advantageous as a liquid for producing the finely atomized droplets in the spray. Of course, other liquids are conceivable and are encompassed by the invention. That depends on the reached temperatures of the plastic containers produced in each case after their thermal forming process.

It has further proven to be particularly favorable when the container is subjected to several times during its transfer with the spray. A particularly preferred variant provides in this context that the spray as a function of the container after the evaporative cooling remaining amount of residual liquid is applied again. In this case, the residual liquid quantity on the container can largely be determined without contact, for example by ultrasound, optically or the like.

Overall, can be achieved by the multiple exposure of the container with the spray during its transfer that the above-mentioned temperatures of 70 ° C or more immediately after the thermal molding process to values of 50 ° C or less are reduced. As a result of this significant temperature reduction, which is reached after a few seconds, usually within a period of less than 10 seconds or less than 5 seconds, it is possible to fill the thus cooled containers directly with the desired product medium. The illustrated transfer times of less than 10 seconds, and preferably even less than 5 seconds, make it clear that the blow molding machine and the filling machine can be easily combined or interlocked with the structural unit.

For the above-mentioned transfer times correspond to transfer routes, which are usually in the range of one or less meters, which must be covered anyway in such machines. That is, the device according to the invention advantageously takes advantage of a combination machine from the blow molding machine and the filling machine with an intermediate transfer line.

In this case, the effectiveness of the treatment with the spray can be further increased insofar as before the (re) application of a spray, the residual liquid remaining on the container is first determined. This amount of residual liquid can be estimated via its layer thickness associated with a liquid film. The layer thickness can be determined without contact on the container, for example by ultrasound or optically. Depending on whether the layer thickness and the resulting residual liquid quantity on the container has fallen below a certain threshold, a compulsory control unit ensures that depending on is reapplied by the residual liquid quantity of the container with the spray.

This can be done so that along the transfer line several spray nozzles or spray mist machines for applying the

Spray mist and measuring devices for determining the thickness of the film

Remaining liquid quantity are arranged. In this case, the spray nozzles or

Spray mist machines and the aforementioned measuring devices along the

Alternating transfer line, for example, be arranged alternately to each other.

The spray nozzle as part of the spray mist machine is generally located on the output side of the atomizing device for the liquid. The atomizing device is generally combined with the compressed gas unit, which applies the atomized liquid with a targeted jet and under pressure to the respective container. In fact, the spray leaves the spray nozzle on the output side of the atomizing device, or an outlet nozzle at the end of an outlet pipe. In this case, the atomizing device can be opened and closed by the already mentioned control unit. In this case, the spray nozzle or outlet nozzle advantageously provides the area of the container which is wetted by the spray mist, that is to say the spray-misted area. This is - as already explained - usually to the areas of the container, which have a particularly large material thickness, such as the floor area.

As a result, a method and a device are described, which are particularly suitable for the combined production and filling of containers made of plastic. In fact, the invention has recognized that the containers can advantageously be cooled during their transfer from the blow molding machine to the filling device or filling machine with a spray mist. As a result, water consumption can be reduced to a minimum, which leads to significant energy savings compared to the previous approaches. In addition, problems with possibly contaminated water practically do not occur. That is, in addition to the energy saving and the low water requirement no running cooling water is observed, which would be elaborately processed and / or collected. Here are the main benefits.

In the following the invention will be explained in more detail with reference to a drawing showing only one embodiment; show it:

1 shows the device according to the invention in an overview,

2 shows the transfer section in detail in plan view, FIG. 3 shows a modified embodiment, and FIG. 4 shows a further modified variant of the invention.

In Fig. 1, an apparatus for the combined production and filling of containers 1 made of plastic, in the present case of plastic bottles 1, is shown. It is a combination machine, with the help of which the bottles or containers 1 in question are produced in a thermal molding process in a blow molding machine 2 and then in a filling machine 3 with a product medium, present and not restrictive with a CO2-containing beverage filled , Between the blow molding machine 2 and the filling device or filling machine 3, a transfer line 4 is interposed, which also belongs to the basic structure.

2 that the transfer section 4 is equipped with a cooling device 5 in order to cool the plastic bottles 1 originating directly from the blow molding machine 2 before they reach the filling machine 3. According to the invention, the cooling device 5 is designed as a spray mist machine. This is composed in detail of a front spray nozzle 5a, a sputtering device 5b and a compressed gas unit 5c together. With the aid of the compressed gas unit 5c, the liquid atomized by the atomizing device 5b is directed with a targeted jet via the spray nozzle 5a onto the respective container or plastic bottle 1 to be treated. 2 is chosen so that the spray mist machine 5 and the spray nozzle 5a the container respectively the plastic bottle 1 bottom side respectively applied to the wall side, so that at this point a liquid film 6 on the container or the Plastic bottle 1 precipitates. For this purpose, the container 1 or the plastic bottle 1 may be rotated when passing the transfer section 4, which is not obligatory.

In the exemplary embodiment, the container or plastic bottles 1 are suspended and transported in the bottom area freely by means of a neck guide through the transfer section 4 to. Since the bottom region of the containers or plastic bottles 1 is kept free from below, the liquid film 6 can be selectively and advantageously applied to the center of the bottle bottom from below. This is because experience shows that the largest accumulation of material in the material for the production of the respective plastic bottle 1 can be found at this point. Of course this is only an example and not restrictive to understand.

In any case, the container or the plastic bottle 1 is cooled by the application of a spray 8. Characterized in that the spray 8 is applied to the container 1 at least in areas of high material thickness, for example in the bottom area, temperature peaks are avoided in these areas.

As a liquid for acting on the atomizing device 5b, the invention recommends water. The gas in the compressed gas unit 5c is air. Due to the fact that the spray 8 or the liquid present therein is deposited as liquid film 6 on and around the container 1, evaporative cooling of the container 1 is achieved.

It can be seen from the illustration in FIG. 2 that the container or the plastic bottle 1 is subjected to multiple sprays 8 during its travel along the transfer path 4. The admission of the Container 1 as a function of remaining after the upstream evaporative cooling residual liquid. That is, the container 1 is first charged with the aid of the first spray misting machine 5. Then, the container 1 moves on and, in its path indicated by an arrow in FIG. 2, subsequently strikes a measuring device 7 along the transfer line 4. With the aid of this measuring device 7, the thickness or layer thickness of the liquid film 6 on the container 1 can be determined. If the layer thickness has fallen below a certain level or no liquid is present at all on the container 1 at this position, the container in question 1 is again subjected to passing the measuring device 7 with a spray 8 in a downstream sprayer machine 5 ¹ .

It can be seen that the respective spray machines 5, 5 'and the measuring device 7 are arranged alternately along the transfer path 4. In addition, both the spray mist machine 5, 5 ¹ and the measuring device 7 are located in the transfer path 4 or are arranged along the transfer path 4. For reasons of measurement reliability, the liquid film 6 or its layer thickness is determined twice at opposite locations with the aid of the measuring device 7, although this is not absolutely necessary, but is only pursued for reasons of accuracy.

In Fig. 1, the blow molding machine 2 is then still shown in detail, which as usual from a preform, also called preform, the bottle or container 1 forms. Here, the mouth or closure region of the preform (preform) already has the final shape. Also known is a method in which the container 1 is formed from a tube of hot moldable plastic. This then happens in the manner that the hose in question is ejected or extruded vertically downward into an associated workpiece. In today's conventional method, the preform is heated, this held in a cavity and enclosed by this. Subsequently, a mandrel moves from above into the preform and compressed air is pressed into the preform, whereby it is inflated and pressed against the contour of the blow mold (cavity) and possibly partially cooled. To this This way, the shape of the desired plastic bottle 1 can be predetermined, these aforementioned methods being known in principle. According to the invention, the compressed air for the described blow molding process can now also be used to pressurize the compressed gas unit 5c, ie it is supplied with an additional benefit.

The plastic bottle 1 and the container 1, after leaving the blow molding machine 2 is still at a temperature which is usually settled above 70 ° C or even more. Along the transfer path 4, the plastic bottle 1 is now preferably cooled in the region of its largest material thickness, usually in the bottom area. This is achieved by applying the spray 8 with the aid of the spray-mist machine 5 or the plurality of spray-mist machines 5, 5 ¹ along the transfer section 4.

As a result, the output side of the transfer line 4 temperatures of the plastic bottle 1 of usually less than 50 ° C observed. The treatment time or cooling time of the plastic bottle 1 is usually not even 5 sec. Thus, the blow molding machine 2 and the filling device or filling machine 3 can be blocked directly together or combined into a single unit. The transfer section 4 is therefore an integral part of this combination machine from the blow molding machine 2 and the filling machine 3.

In the variant of FIG. 3, there is the spray nozzle or outlet nozzle 5a for the spray at the end of an outlet pipe 9 of the spray mist machine 5 respectively 5 ^first In this case, the outlet pipe 9 or the spray nozzle or outlet nozzle 5a is directed onto the bottom region of the plastic bottle 1. The plastic bottle 1 is transported in this case in the transfer section 4 circumferentially by means of a merely indicated carousel. The spray mist machine 5 or 5 ', may again have the atomizing device 5b for liquid, in particular water and the compressed gas unit 5c, which are not explicitly shown in the context of FIG. 3. In the atomizing device 5b, the compressed gas unit 5c, the outlet pipe 9 and finally the spray nozzle or outlet nozzle 5a is a total of means 5a, 5b, 5c, 9, which serve to guide the spray nozzle 5a leaving the spray.

To these means 5a, 5b, 5c, 9 for guiding and / or limiting the spray occur in the context of the illustration of FIG. 3 further means 10 in the form of a local shut-off device 10 added. With the help of this shut-off device 10 or shut-off the spray mist machine 5, 5 'is sealed off, and primarily against a mouth 1a of the container or the plastic bottle 1. In fact, by these means 5a, 5b, 5c, 9; 10 ensures that a spray-mist-free area 11a and a spray-mist-covered area 11b are defined on the outer surface of the container or the plastic bottle 1. In fact, the shut-off device 10 seals off the spray-mist machine 5, 5 'from the spray-mist-free region 11a of the container 1.

For this purpose, the shut-off device 10 has a gap or slot 12, which is adapted to the outer dimensions of the container or the plastic bottle 1. Through this gap or slot 12, the plastic bottles 1 along the transfer section 4, in the example of the carousel circular, out. This ensures that the spray mist 8 leaving the spray nozzle 5a is kept away from the spray-mist-free region 11a of the plastic bottle 1 and in particular the bottle mouth 1a, so that spray mist 8 can not get inside the plastic bottle 1.

In the context of the invention, the shut-off device 10 can be changed in their height H, as indicated by a double arrow in FIG. 3. As a result, different formats of the plastic bottles 1 can be processed without difficulty, and ultimately the extent of the spray-mist-free region 11a and that of the spray-affected region 11b can be set variably and according to requirements. Of course, a width B of the gap or slot 12 can be changed, depending on which format the plastic bottles 1 have. In this way can be with the shown device easily process all common plastic bottles 1, for example, from a 0.5 liter bottle to a 2.5 liter bottle.

4, an additional means 13 in the form of a gas flow device 13 is still provided in order to achieve a guidance and / or limitation of the spray 8. In fact, a gas flow indicated by arrows emerges from the gas flow device 13. This gas flow is directed to the spray-free region 11a of the container or the plastic bottle 1, in the present case forms a gas flow veil, which acts primarily on the bottle opening 1a. Incidentally, the gas flow is also directed to the slot or gap 12 and may be sucked out along the slot or gap 12, for which purpose only a suction device 14 is provided. However, this is not mandatory.

In any case, with the help of the gas flow device 13 and the gas flow leaving it is achieved that the plastic bottle 1 is acted upon in the spray mist region 11 a with a gas stream curtain, which prevents reflected in this area spray 8 on the plastic bottle 1. For this purpose, it may be the gas flow to a sterile air flow, which prevents bacteria from entering the bottle via the mouth of the bottle 1a. Further, the air or the gas used for the gas flow is of course dried to prevent liquid precipitation in the mist-free region 11a on the plastic bottle 1. Most of the work is carried out at this point with flow rates, the gas velocity of about 0.1 m / sec. correspond, which of course is only an example and not obligatory to understand.

In the variant according to FIG. 4, consequently, the entire transfer section 4 is located in an enclosure 15, which at the same time as the

Shut-off 10 is equipped in the interior in the form of, for example, an intermediate wall or an intermediate floor. This separates the shut-off device 10 or the intermediate bottom, the gas flow device 13 in the upper part of the housing 15 of the spray mist machine 5 and 5 ¹ in the lower part.

The means 5a, 5b, 5c, 9; 10; 13; 14 for guiding and / or delimiting the spray 8, individually or in any combination with one another, can ensure that the plastic bottle 1 is subdivided on its outer surface into the desired spray-mist-free region 11a and the mist-sprayed region 11b. Incidentally, it is possible with the aid of these means 5a, 5b, 5c, 9; 10; 13; 14, of course, also define and specify the extent and shape of the respective spray-mist-free area 11a and of the spray-misted area 11b. For this purpose, a not explicitly shown and already mentioned in the introduction control unit may be realized. This ensures the control of the blow molding machine 2, the filling machine 3 and the transfer line 4 as well as for the application of the spray mist machine 5 or 5 '. In addition, with the help of this control unit, the format of the plastic bottle 1 to be processed in each case may be taken into account by the fact that the height H of the shut-off device 10 or of the intermediate bottom within the housing 15 undergoes a corresponding variation. Comparable may apply to the gap 12, which can be adjusted remotely by its size.
