Description

The invention relates to a blow molding machine for converting plastic preforms to plastic containers comprising a plurality of blowing stations with Blasformträgern for holding blow molds, comprising a clean room for arranging or transporting the blowing stations under aseptic conditions and comprising a Rüstzugang the clean room for equipping the blow mold with blowing station components.

The invention also relates to a method for exchanging blowing station components of a blowing station in a clean room of a blow molding machine, in which the clean room is opened and in which the blowing station components are exchanged.

In addition, the invention relates to both a beverage filling plant and a beverage container manufacturing plant.

Generic blow molding machines, in particular stretch blow molding machines, beverage filling plants and / or beverage container production plants are well known from the prior art.

For example, the published patent application DE 10 2008 038 141 A1 a plant for producing plastic containers with a clean room in which the plastic containers are both produced and filled with drinks. In this respect, the manufacturing plant comprises a device for forming plastic preforms to the plastic containers and a filling device for the latter. The forming apparatus has a plurality of blowing stations with blow mold carriers for holding blow molds in which the plastic preforms are expanded to the plastic containers. The object of DE 10 2008 038 141 A1 is hereby incorporated by reference in its entirety to the disclosure content of the present application. It is understood that for the production of differently shaped plastic containers, for example with regard to a volume and / or a contour, also different blow molds must be used on the forming device. A corresponding exchange takes place here on the forming device manually, by exchanging a first blow mold set with blow molds of the first type for another blow mold set with blow molds of the second type. After replacement, not only the new blow molds must be sterilized within the clean room to prevent contamination of the plastic preforms or plastic containers with germs, but also the previously opened clean room itself.

In order to facilitate replacement of the blow molds, it is known to provide a blow mold set to be exchanged in a mobile magazine device, in which the blow molds are picked up individually on receiving means of a carrier device. Here, a transfer of the individual blow molds between a blowing station of a forming device and the magazine device can be done manually or at least semi-automatically. Some mobile magazine devices can have a cleaning device by means of which, for example, the blow molds can be immediately rinsed, cleaned, polished, disinfected and / or sterilized.

As a result, although already sterilized and thus ready for use blow molding can be provided. Nevertheless, there is still the danger that the clean room will be contaminated during opening and therefore after the replacement of the new blow molds a sterilization of the clean room and the equipment, tools, etc. therein must be mandatory. However, this leads to a considerable delay in production.

It is an object of the invention generic systems, in particular generic stretch blow molding machines, further develop such that the risk of contamination of the clean room and the devices and tools located therein with germs is excluded.

This object is achieved on the one hand by a blow molding machine for converting plastic preforms to plastic containers comprising at least one and preferably a plurality of blowing stations with blow mold carriers for holding blow molds, comprising a clean room for arranging or transporting the blow stations under aseptic conditions and comprising a setup access of the clean room for setup the blow mold carrier with blowing station components dissolved, in which the set-up access comprises at least one sterile room, which is upstream of the clean room with the plurality of blow molding stations on the environment side.

According to the invention, in addition to the actual clean room, in which the treatment, ie in particular the production and / or filling, the plastic containers, there is another sterile room through which allows a replacement of the blow molds at a Rüstzugang the blow molding machine under sterile or aseptic conditions is. By means of this new setup access, the actual clean room of the blow molding machine can be opened without danger for the replacement of a blow molding set without contaminating both the clean room and devices located therein, such as blowing tools, by germs from the surroundings.

The present invention is particularly advantageous in the beverage industry, since plastic bottling bottles and beverages to be filled therein, which are very sensitive to germs, are often processed there. Therefore, on the other hand, the object of the invention is also achieved by a beverage bottling plant and / or a beverage container manufacturing plant, which is characterized by the present blowing machine.

It is conceivable that in addition to a beverage bottling plant or to a beverage container manufacturing plant at a plurality of areas or treatment machines, a set-up access can be advantageously used with such an additional sterile room. For example, on a filling machine or on a dishwasher for changing CIP caps, in a capping machine for changing capping, in a cleaning or sterilizing machine with container-dependent nozzles and in general also for changing format parts in container transport units.

The term "clean room" in the sense of the invention here describes a process space in a processing line of the blow molding machine, in which the plastic containers are traded under sterile conditions due to the process.

The term "sterile room" in the context of the invention describes a region of the blow molding machine, through which machine-relevant components can be brought under sterile conditions into or out of the clean room.

Preferably, the clean room can be brought into fluid communication with the sterile room. Advantageously, a flow connection between the clean room and the sterile room can be interrupted.

The term "blow molding machine" specifically covers a stretch blow molding machine.

Advantageously, the blowing station components may in particular include blow molds, bottom molds, stretching rods, stretch rod stops, holding clamps, gripping clamps, blowing nozzles or the like.

A preferred embodiment variant provides that the setup access on the one hand comprises an environmental lock for accessing the sterile room and on the other hand an exchange lock for introducing or removing the blowing station components into or out of the clean room. This allows easy access to the sterile room, without risking contamination of the clean room.

In this case, the sterile room can be advantageously charged with blowing station components while it is still separated from the clean room. If a loading of the sterile room has taken place and the environmental lock is closed again, sterilization of the sterile room and of the blowing station components arranged therein can take place. Subsequently, the exchange lock and thus the clean room can be opened without danger.

In this respect, the object of the invention is also achieved by a method for exchanging blowing station components of a blowing station in a clean room of a blow molding machine, in which the clean room is opened and in which the blowing station components are exchanged, in particular in the opened clean room, wherein the blowing station components are exchanged under sterile conditions.

It is advantageous if the blowing station components are exchanged in a sterile room or through a sterile room in a sterile environment, since this can considerably shorten set-up times.

If the environmental lock and the exchange lock are located directly opposite one another, the set-up access can be made very compact, since in particular blow molds can be passed vis-a-vis through the set-up access.

It is possible that a sterile room of the retrieval access can be configured immediately by a correspondingly designed housing of a clean room.

If the setup access has a housing enclosing the sterile room, which is detachably arranged on a clean room wall, conventional or already constructed blow molding machines can also be easily retrofitted.

In particular, such a detachable setup access can be advantageously repositioned or temporarily arranged with the housing enclosing the sterile room also at different areas of a beverage container treatment plant, namely, where a corresponding set-up process is currently to be carried out under sterile conditions.

A particularly preferred embodiment therefore also provides an exchange lock for introducing or removing the blowing station components into or out of the clean room, wherein the replacement lock comprises an openable partition wall of the setup access, preferably a partition on the inside of the room and a dividing wall on the clean room side.

The setup access can be easily removed from the clean room wall for maintenance purposes, for example, if the clean room side partition is closed, since contamination of the clean room by germs can be excluded. If then the sterilraumseitige partition is closed, the risk of sterilization room side contamination can be excluded. In particular, this is also advantageous in the case of a relocation of the present setup access.

Moreover, it is advantageous if the setup access comprises an automatically or at least semiautomatically actuatable device for transferring the blow station components from the sterile room into the clean room and / or vice versa. As a result, a replacement of the blowing station components can be accelerated, whereby the set-up time can be advantageously reduced.

Advantageously, the transfer device has a gripper for gripping and transferring the blowing station components, by means of which, for example, each blow mold can be gripped. Thus, in particular, a blow mold to be exchanged can be removed from a blow mold carrier of a blow station by means of the gripper and transferred to a free holder within the setup access. Subsequently, a new blow mold can be taken from a further receptacle of the setup access and transferred to the previously emptied blow mold carrier. This procedure can be continued until the complete blow molding set has been replaced.

It is understood that such an exchange can also be carried out manually or by means of a different design.

It is also advantageous if the setup access comprises a preferably rotatable blowing station component holding device, so that a setting-up process, in particular of a complete blow-molding set, can be carried out quickly and easily. It is conceivable that differently constructed holding devices can be used.

So that a coordination between the individual devices, such as the exchange lock, the preferably rotatable blowing station component holding device, a pureraumseitigen Blasformenrades and the transfer device can be automated, it is advantageous if this is a control device is provided by means of which the corresponding functional processes can be performed at least partially automated ,

Furthermore, it is advantageous if the set-up access comprises a sterile gas supply which has a connection to a clean-room sterilant gas supply. Thus, sterilization at the set-up access can be realized structurally simple.

In order to prevent the danger of contamination of the clean room and the sterile room equally exceptionally well, it is of particular advantage if a clean room working air pressure is higher than a sterile room working air pressure of the setup supply and the sterile room working air pressure is higher than the atmospheric air pressure. In this way, on the one hand, the risk can be reduced that an air exchange can take place from the sterile room into the clean room. On the other hand, air exchange from the environment outside the stretch blow molding machine into the sterile room can thus be avoided well.

In this respect, a set-up access with an advantageous two-stage compressed air barrier is provided in the present case. This alone can be used to develop a blow molding machine with a clean room, in particular a stretch blow molding machine, without the other features of the invention.

Further advantages, objects and features of the present invention will be explained with reference to the appended drawings and the following description, in which an example of a beverage container treatment plant is shown and described with a stretch blow molding machine comprising at least one set-up access according to the invention.

The mobile exchange lock door 56 and the blow mold carrier 22 are suitably controlled automatically. However, a manual operation is conceivable, for example, the service intervention 39 can be done. The hygienically designed transfer device 57 changes when the exchange lock door is open 56 the blow mold sets 46 and 47 out.

Generally, the gripper can 58 and the exchange lock 52 Also used to place items in the clean room 15 into or out of the clean room 15 to be taken out, such as improperly shaped plastic beverage bottles 6 ,

The setup access 40 can be identical or similar designed several times, especially in the field of blowing wheel 24 to be available. Depending on the plant or machine size and requirement, the arrangement in position and position this can be selected appropriately.

For sterilizing the individual blow molds 48 within the setup access 40 is still a sterile gas supply 60 with at least one cleaning nozzle 61 intended. Here, each of the in the sterile room 41 arranged blow molds 48 temporarily in front of the cleaning nozzle 61 parked and cleaned.

Preference is given to the clean room 15 sterilized with a tempered gas mixture of H ₂ O ₂ and air. Cleaning is not mandatory before each sterilization.

Appropriate is also the setup access 40 sterilized with gas. This is necessary if, for example, an unsterile blow molding set 48 from the operator 55 in the sterile room 41 is introduced. So can the blow molds 48 already during the production of the plastic beverage containers 6 equipped or by means of one or more cleaning nozzles 61 be cleaned and sterilized. The various blow molds can be useful here 48 be brought to distance A to wet all surfaces well.

As especially good from the presentation after the 2 It can be seen, is the beverage treatment plant 1 in a sterilizable area 65 and an area 66 , which is cleanable and sterilizable, divided.

The sterilizable area 65 begins after the sterilization of the plastic preforms 5 on the sterilization wheel 20 and ends at a transfer unit 67 between the stretch blow molder 4 and the beverage bottling machine 8th the beverage bottling unit 3 ,

The cleanable and sterilizable area 66 begins immediately after the sterilizable area 65 and ends after applying closures on the plastic beverage bottles 6 at the capping machine 9 with a closure sterilization unit 70 for closures 70A , It is particularly advantageous that the other blow molds 48 in the scaffold access 40 be cleaned automatically. Preferably, the beverage container treatment plant 1 total dry sterilized.

Furthermore, the beverage container treatment plant comprises 1 one to the heater 7 belonging oven 71 for heating the plastic preforms 5 and an additional plastic beverage bottle lock 72 ,

During production, a well-known evaporator supplied 75 the sterilization wheel 20 the plastic preforms 5 and / or the seal sterilization unit 70 , In order to produce several required quantities for different operating conditions of H ₂ O ₂ -air mixture, the evaporator 75 over two or more ways 76 and 77 from a H ₂ O ₂ ring line 78 fed.

The air supply can either be from the environment 42 and / or from a ventilation system 80 with a filter 80A respectively. 81 (please refer 1 and 3 ) of the beverage container treatment plant 1 and / or from the exhaust device 82 of the oven 71 come. Absolute safety in terms of purity is a candle filter element 83 in the supply line of the supply air.

The H ₂ O ₂ ring line 78 can be more customers 84 have to order more units of the beverage container treatment plant 1 to supply. For example, hydraulic sealing systems can be used together with a water connection 85 be supplied.

Because the evaporator 75 during production should not be adversely affected, it is advantageous that the further blow mold set 47 over another evaporator 86 can be sterilized as this process should be temporarily scheduled during production.

By means of the second evaporator 86 Furthermore, the additional plastic beverage bottle lock can also be connected via a pipe 72 be sterilized at least temporarily.

About the additional plastic beverage bottle lock 72 For example, defective plastic beverage bottles 6 or sample container (not shown here) from the current process via a transfer wheel 73 be removed or disposed of.

After production becomes the cleanable and sterilizable area 66 preferably automatically cleaned with lye over one or more spray nozzles and / or rotary heads (not shown here) and then rinsed with water, preferably with drinking water quality.

Subsequently, the cleanable and sterilizable area 66 to be dried. The beverage container treatment plant 1 can then be put into a sleep state.

Before the next production, the various components of the beverage container treatment plant 1 be sterilized. These must be heated. Appropriately, tempered air 90 in a piping system 91 fed.

Subsequently, the beverage container treatment plant 1 preferably dry sterilized with H ₂ O ₂ . Both evaporators 75 and 86 can into the piping system 91 feed and thus accelerate the process. Also, H ₂ O _{2 may be} from the piping system 91 at a connection 92 be diverted to, for example, the first ventilation system 80 and / or another pipeline system, such as a nozzle system for cleaning the beverage container treatment plant 1 , and / or to sterilize non-plant units.

The clean room 15 and the sterile room 41 are subjected to filtered air, so that an overpressure to the surrounding atmosphere is ensured. In the present case, the overpressure is determined by a machine control (not shown here) by means of one or more pressure sensors 100 and 101 supervised.

A particularly successful plastic beverage bottle production ensures, for example, the following pressure ratio: p ₁ > p ₂ > p _at , wherein in the present case p _{1 is} the clean room working air pressure 102 , p ₂ the sterile room working pressure 103 and p _at the atmospheric pressure 104 is. To the risk of contamination by germs, especially in the stretch blow molder 4 To reduce even further, is the clean room working air pressure 102 higher than the sterile room working air pressure 103 the setup supply 40 and the sterile room working air pressure 103 higher than the atmospheric pressure 104 set.

It is expedient to supply sterile air via a central ventilation system 80 respectively. 81 processed and fed via pipelines to the various cleanroom sections. The control of the air flows usually take over seat and flap valves 105 (only exemplified).

Optionally, there is also an exhaust system with respect to the second ventilation system 81 required if directional flow is desired. Part of the air can also be in a cycle 106 be driven. The ventilation system can also supply other clean rooms of machines, such as the beverage filling machine 8th , Closing machine 9 or parallel installations (not shown here). In general, it is desirable that the process technology be combined with other container handling equipment. The ventilation system 80 can also be sterilized from the back.

In particular, the representation after the 3 shows schematically well the operation of the ventilation technology of the present beverage container treatment plant 1 that in unsterile areas 110 and 111 into a sterilization area 112 for sterilizing the plastic preforms 5 and in a sterile area 113 is divided. The sterile area 113 begins during the sterilization of the plastic preforms 5 and ends after the closure on the respective plastic beverage container 6 is applied. This entire area must be kept under pressure during production.

There are also the areas 65 and 66 showing the filling area of the present stretch blow molding machine 4 delimit.

At the transfer unit 67 , which represents a lock system is preferably sucked off, so that during production no aerosols from the filling process in the sterilizable area 65 reach. Additionally, at the transfer unit 67 a supply air 114 be connected, so that always an overpressure to the atmosphere can be kept. Throughout the sterile area 113 should not be below an overpressure of 5 Pascal.

On the feed side of the plastic preforms 5 is also a lock system in the form of the plastic preform feed 19 Installed. There in particular on the sterilization wheel 20 a hot H ₂ O ₂ air mixture for sterilizing the plastic preforms 5 it is necessary to have the same pressure level on both sides (p ₁ ≈ p ₈ ≈ p ₇ > p _at ). This is on the one hand by a second supply air 115 and on the other hand by a third supply air 116 guaranteed. Whereby a majority of the volume flow of the second supply air 115 over the exhaust air 117 is sucked off.

Also on the outlet side must be an airlock 118 be present to a clear separation between the sterile area 113 and the first non-sterile area 110 to have.

During the sterilization of the beverage container treatment plant 1 is preferably used hot H ₂ O ₂ -air mixture, as already mentioned. For this purpose, the spout becomes 118 with a single flap 119 at least partially closed.

With regard to the introduction of objects during a production interruption, it is useful for the purpose of plant flexibility meaningful format-dependent parts, such. B. blow molding 30 respectively. 48 into the sterile zone of the clean room 15 , especially in the stretch blow molder 4 , via a retrofit access 40 contribute.

For introducing the blow molds 48 must be the environmental lock door 54 be opened, causing the setup access 40 is not sterile. After closing the environmental lock door 54 become the blow molds 48 in the sterile room 41 of the equipment access 40 preferably with the H ₂ O ₂ air mixture via a H ₂ O ₂ air mixture supply 120 sterilized. From the H ₂ O ₂ air mixture supply 120 If appropriate, plastic preform sterilization or the filters of the ventilation system can also be used 80 (please refer 1 ) are sterilized. After the sterilization of the blow molds 48 should the sterile room with filtered air from the ventilation system 80 be rinsed. This is also an exhaust air 121 necessary. Before opening the exit lock door 56 Must be the pressure between the clean room 15 and the sterile room 41 be brought to the same level (p ₁ ≈ p ₂ ). Then the new blow molds 48 in the clean room 15 introduced or existing blow molding 30 from the clean room 15 should be removed without violating the sterility. During production, the following pressure states must always be ensured: p ₁ , p ₃ , p ₄ > p _at .

It goes without saying that the exemplary embodiment explained above is merely a first embodiment of the stretch blow molding machine according to the invention 4 is. In this respect, the embodiment of the invention is not limited to this embodiment.
