Description

The present invention relates to a device for labeling containers and in particular plastic containers. Such devices have been known for a long time from the prior art. In the context of the present invention, devices for labeling are understood as devices which attach a label material to the containers. This label material can be labels, which are applied with a glue layer and then attached to the containers. However, it may also be self-adhesive labels, which are subtracted from a substrate and then adhered to the container.

In addition, the labels may also be so-called shrink sleeves, which are slipped over the containers and then shrunk onto this, in particular by thermal action. It may also be stretchable sleeves, which are raised only by mechanical force on containers. Also, the label material may be color that is applied to the containers.

Such devices usually have a transport device which transports the containers. In addition, these devices also have an application device which attaches the label material to the containers. This application device is usually arranged stationary and attaches the labels to the moving containers.

From the EP 2 332 845 A2 For example, a labeling apparatus and a labeling method for labeling containers are known. This labeling device has a sterilization device for sterilizing the containers or a tool. This sterilization device is intended, for example, to sterilize a centering bell which holds the containers during the labeling process.

From the DE 10 2008 024 947 A1 a method for packaging patient-specific substances and a system for carrying out the method is known. The packaging takes place within a clean room.

Recently, it has begun to fill in many areas containers under sterile conditions. However, this requires that even the containers to be filled should arrive sterile at the filling machine. For this reason, sterile production machines have become known recently, with which plastic preforms are transformed under sterile conditions to plastic containers.

Both the filling machines and the forming machines, for example stretch blow molding machines, have in common that the containers that treat the containers, for example filling valves, blow molding stations, stretching bars and the like, are moved along with the containers. For this reason, usually these elements are usually integrated into the clean room.

Furthermore, the Applicant has recently developed devices which already sterilize the plastic preforms prior to the expansion process. This has the advantage that the consumption of sterilizing agent compared to the sterilization of containers can be kept lower. Also, the treatment time of the plastic preforms can be kept lower in these cases.

However, this procedure required so far that the labeling was carried out after the filling process. However, this labeling of the containers after the filling process has the disadvantage that the containers, often caused by the filling process, are still moist, which makes labeling difficult. In addition, a bottling for bottled bottles is difficult to accomplish due to the weight.

The present invention is therefore based on the object to provide a device which allows a sterile treatment or promotion of the containers, at the same time, however, the labeling of the containers should not be hindered by, for example, a high level of moisture. In addition, a sterilization of the containers should also be able to be advantageously carried out in a labeling machine, whereby the containers can advantageously be both plastic preforms and plastic containers produced from these plastic preforms.

These objects are achieved by the subject matter of the independent claims. Advantageous embodiments and further developments are the subject of the dependent claims.

A device according to the invention for labeling containers has a transport device which transports the containers along a predetermined transport path. Furthermore, the device has a feed unit, which supplies the label material to the containers or makes available. In addition, the device also has an application device, which attaches the label material to the containers.

According to the invention, the device has a clean room, which is delimited by means of at least one first wall with respect to an unsterile environment, this clean room at least partially surrounding the transport path of the containers, in particular such that the containers are moved within this clean room.

It is therefore proposed according to the invention that the labeling machine is kept in a controlled environment under clean room conditions, so that containers are not contaminated during the passage or during the labeling process.

Such measures have hitherto always been prevented in labeling machines, since it was assumed that the labeling process itself may already be associated with contamination (for example due to the adhesive used). In addition, in a labeling machine the additional problem arises that it usually also has stationary parts of the system which thus do not move with the containers to be labeled.

The label material can be, for example, labels to be coated with glue, self-adhesive labels, tubes, shrink films, but also ink material or the like.

The invention would also be conceivable for laser labeling, wherein the applicant reserves the right to claim protection even for such labeling of containers, which takes place in particular in a clean room.

In an advantageous embodiment, the clean room has a second wall which delimits the clean room from the environment and the first wall is relatively movable relative to this second wall. It is possible that the two walls against each other by means of a hydraulic seal, such as a water castle, sealed.

Similar to a filling area of a filling machine or in the space of a blow molding machine, it is advantageous for achieving the clean room conditions to take measures to keep the space through which the containers are transported sterile. Advantageously, at least some, and preferably all curves, drives and elements, which are not necessarily required for transport and treatment, are arranged outside of said clean room. This facilitates on the one hand assembly work and on the other hand reduces the risk of contamination within the clean room.

Advantageously, the transport device has a rotatable about a predetermined axis of rotation on which the individual transport elements for transporting the containers are arranged. Thus, the containers are advantageously at least partially or partially transported along a circular path. With rotating machines, a hydraulic seal between a stationary and a rotating part of the machine is also advantageous in order to be able to supply these with a sufficient overpressure. But it can also be provided a rubber seal, such as a labyrinth seal. Advantageously, a supply device is provided, which introduces a gaseous medium, in particular, but not exclusively sterile and / or filtered air, into the clean room. Advantageously, the device also has a fine filter unit (FFU). This fine filter unit acts advantageously on the clean room with an overpressure relative to the (atmospheric) environment of the clean room. However, it would also be conceivable to supply the device with adjacent sterile machines located in adjacent clean rooms, such as, for example, the filler with sterile air.

As mentioned, the difference to the already mentioned blowing machines and a filling machine is that not all treatment units are co-rotating in the case of a labeling machine. The labeling units as treatment units are usually arranged stationary with respect to the movable or rotating containers. This results in differences that make the design of a labeling machine as a sterile machine consuming. In particular, it is more expensive here to keep the clean room under an overpressure.

Advantageously, all moving parts are sealed within the clean room with sealing devices, as sealing means, for example, water locks, vapor barriers, bellows or seals made of rubber materials come into question. The drives, such as cam rollers, motors and gears of these elements, in particular those of the turntable, are advantageously arranged outside the clean room, so that even a lubrication of these elements is not a problem. However, it would also be possible for the forces to be transmitted magnetically and for this magnetic effect to have an advantageous effect through the clean room boundaries.

In a further advantageous embodiment, the device has a cleaning device for cleaning the clean room and / or moving within the clean room elements. Advantageously, therefore, the clean room itself and also prefers all moving components therein CIP-bar (cleaning in place) and / or SIP-bar (sterilization in place).

In a further advantageous embodiment, inclined surfaces are arranged within a clean room through which a liquid medium can flow. Thus, for example, the clean room can be cleaned by means of a liquid sterilization medium and this sterilization medium can then flow, for example, into a collecting channel.

In a further advantageous embodiment, an outer wall of the clean room is stationary and an inner wall rotates relative to this outer wall. It is possible that over the outer wall containers are supplied for the purpose of labeling and preferably also removed again.

In a further advantageous embodiment, the transport device itself can also form a wall of the sterile room. The device preferably has a storage unit for storing the label material.

In a further advantageous embodiment, the above-mentioned storage unit is arranged at least in sections and preferably completely outside the clean room. This storage unit may, for example, be a roll magazine which makes the labels available, but it would also be conceivable that this is a magazine which, for example, provides shrink sleeves or also that this is simply a Tray is in which the label stock is stored.

Also advantageous is the feed unit, which supplies the containers the label material, at least partially disposed outside of the clean room. Preferably, at least a portion of the feed unit extends through a boundary of the clean room. It would also be possible for the application unit and the delivery unit to jointly form a structural unit. It would also be possible that the label material is supplied to the containers through a border of the clean room.

In a further advantageous embodiment, however, it would also be possible for the application units or labeling units themselves to be located inside the clean room. This would be useful, for example, for hot-glue labeling, but it would also be possible to use other labeling methods in this way.

It would also be conceivable to use complete clean room units in this way, which can be docked and also centered on the machine in just a few simple steps, just like previous modular machines. The clean room units can even provide or form part of the clean room wall, which itself can be docked to the clean room of the machine via suitable sealing means. For this purpose, it is also possible to provide locks (for example movable sheets) on the machine and / or on the clean room units which ensure a seal against the non-sterile zone during a change of unit.

In a further advantageous embodiment, the device has a sterilization device for sterilizing the clean room. This may be, for example, a sterilization device, which acts on the clean room with a flowable sterilization medium. However, it would also be possible that it is a sterilization device, which acts on the clean room or walls of the clean room with ozone or radiation, for example, electron radiation, gamma radiation or UV radiation.

In a further advantageous embodiment, facilities are provided which hold the clean room under an overpressure.

It would also be possible to provide a sterilization device which sterilizes the label material itself. For example, it would be possible for label magazines or label rolls to be driven through a dipping bath with hydrogen peroxide or a lock before they are used.

Thus, the labels can also be sterilized before, during or after attachment to the containers. For this purpose, gaseous hydrogen peroxide is suitable in a preferred embodiment, so that no liquid adheres to the labels, so as not to impair the adhesion to the containers. For example, labels may also be heated above the dew point of hydrogen peroxide prior to application so as to be subsequently applied thereto.

It would also be possible to sterilize the labels by means of heat or heat, if the corresponding label material is designed for this purpose. Sterilization in an immersion bath would also be conceivable, for example in peracetic acid or liquid hydrogen peroxide (H ₂ O ₂ ). It is also intended to sterilize the labels by means of ozone, UV light, gamma radiation, photodynamics or electron radiation.

The labels are preferably sterilized shortly before or after entry into the clean room. But it can also be provided a kind of lock in which the labels are sterilized before they enter the clean room, in which the containers are transported.

It would also be conceivable to use antibacterial adhesives instead of hot glue, for example also for the labeling of a carrier tape. Such adhesives could be carried out containing iodine or silver ions. As examples of silver-containing additives, mention may be made of zeolites, glass ceramics, nanoparticle metallic silver, nanosilver-coated polymers, silver salts or the like.

It is therefore proposed in a further advantageous embodiment, the use of an adhesive which is mixed with the above additives. For this purpose, an adhesive with a hydrophilic base polymer is preferably used. These include, for example, formulated and UV-light-crosslinkable pressure-sensitive adhesives or else hydrocolloids, for example based on thermoplastic rubber.

If a Schlauchetikettierung or labeling is carried out by means of carrier tape, the carrier tape or the label may also have a particular non-visible perforation through which a sterilization agent can reach the covered areas of the label.

Therefore, a sterilization device for sterilizing the label material is also proposed. In particular, a sterilization device is provided, which acts on the label material with a flowable sterilization medium or with a sterilizing radiation.

When using tubular labels, it is also conceivable to separate the individual hoses from each other before and then to apply to the containers.

Another possibility for the labeling is the use of a stretchable tube, which is pre-stretched mechanically, for example, by spreading fingers. After slipping the label over the container, the corresponding spreading fingers are moved out again between the container and the label. In this way, a sterilization of the label in the phase, for example, electron radiation or ultraviolet radiation could take place, since just the label is widened on the said spreading fingers. It would also be conceivable in this embodiment that nozzles are provided which are mounted between the spreading fingers and in which also H ₂ O ₂ can escape. Furthermore, a combination with the function of removing via (sterile) air nozzles and / or sterilization would also be conceivable here.

In a further advantageous embodiment, the transport device, as mentioned above, a rotatable about a predetermined axis of rotation carrier, wherein a rotation axis is preferably arranged outside of the clean room. Particularly preferably, the clean room is channel-like formed around the transport path of the containers. Also, the rotatable support itself can form a wall of the clean room. In this way, the clean room can be kept relatively small.

In this embodiment, it is conceivable that the clean room is at least partially annular and has a feeder or an inlet and a drain for the containers. However, it would also be possible that in addition to the axis of rotation even more elements, such as in particular the drive outside the clean room are arranged. Other moving parts that may be located outside of the clean room are, for example, drives for turntables and centering bells or also drives for neck handling clamps. These drives are advantageously also arranged outside of the clean room.

In a further advantageous embodiment, the device has a sterilization device, which sterilizes the containers during transport through the labeling machine.

In a further advantageous embodiment, the application device is modular and can be removed in its entirety from the transport device. It is possible that the application device is both mechanically and electrically connected and disconnected.

In a further advantageous embodiment, there is at least one drive for transporting the containers and / or the labels outside the clean room.

In a further advantageous embodiment, at least one sterilization device is provided for sterilizing the labels, and preferably at least one sterilization device for sterilizing the labels is arranged on the device.

In addition, as mentioned above, it would also be possible for the labeling unit to be arranged inside the clean room and for drives for the labeling unit to be arranged at least partially outside the clean room. It would also be possible that portions of the labeling unit or the application device are arranged outside the clean room.

However, it would also be conceivable to design the labeling units outside of the clean room, but in line, in particular co-rotating. In this way it would be possible to ensure an even easier seal. The disadvantage that each conveyor, especially turntable, a separate unit would be assigned, would be taken in the case deliberately accepted.

The present invention is further directed to a plant for treating containers, this plant having at least one device of the type described above for labeling the containers and a filling device, which is arranged according to this device for labeling the containers.

Advantageously, the containers are plastic containers. However, it would also be an application to glass containers or containers made of other materials conceivable.

Preferably, however, the system has a forming device for forming plastic preforms into plastic containers, this forming device preferably being arranged upstream of the above-mentioned labeling device. It is therefore proposed here that the labeling of the containers between a manufacturing process of the containers and a filling of the containers is performed.

In a further advantageous embodiment, the containers are transported from the forming device to the filling device continuously in the region of its thread or below a support ring. In other words, the containers are transported in the forming device, in the labeling machine and in the filling device in the neck handling. It is therefore proposed a continuous neck handling of blowing wheel to the filling device. Advantageously, the containers between the forming device and the filling device are transported isolated. In this way can be dispensed with transport facilities such as air conveyor and the like. This can reduce the risk of damage to the containers. Also, such a sterility of the containers can be better ensured.

In particular, the containers are transported from the forming device via the labeling machine to the filling device in a continuous clean room. In this case, a pressure gradient can be within this clean room or result. The highest pressure is preferably in the filling device, while in the labeller and the forming device, a lower pressure is present, which is still higher than the ambient pressure outside the clean room. The air pressure gradient results in an air flow with sterile air from the filling device in the direction of the labeling machine.

Since it u.U. it is necessary to suck off any residues of the treatment in the labeling machine (paint, glue residues) at the point of origin, or else to compensate for leaks in the labeling machine, blowers for introducing sterile air into the labeling machine can be present. In other words, the pressure produced by the filling device is not sufficient, depending on the embodiment, to keep the labeling machine under pressure alone.

In particular, the pressure in the labeling machine is slightly lower than in the area upstream and / or in the forming device in order to be able to suck said residues within the labeling machine and not to distribute them. For sucking off the residues, it is also possible to provide suction in the area in front of the labeling machine and suction in the area downstream of the labeling machine. In some cases, it can not be prevented that (contaminated) ambient air enters the labeling and contamination of the containers takes place. Nevertheless, the use of the proposed means for creating a clean room can nevertheless be helpful here, because e.g. in a subsequent sterilization of the containers only less sterilant must be used, as in the sterilization of a completely contaminated container. In other words, in these cases, the containers are only slightly germinated.

• – Ein durchgängiger Reinraum von einer vorgelagerten Spritzgussmaschine bis zum Verschließer, in diesem Fall erfolgt keine weitere Sterilisation der Behältnisse.
• – Ein durchgängiger Reinraum von einer vorgelagerten Spritzgussmaschine bis zum Verschließer, Sterilisation der Kunststoffvorformlinge findet vor deren Umformung statt und keine weitere Sterilisation.
• – Ein durchgängiger Reinraum von einer vorgelagerten Spritzgussmaschine bis zum Verschließer, die Sterilisation der umgeformten Behältnisse erfolgt vor und/oder in und/oder nach der Etikettiermaschine.
• – Ein durchgängiger Reinraum von der Sterilisation der Vorformlinge vor der Umformungseinrichtung bis zum Verschließer, es erfolgt keine Sterilisation der umgeformten Behältnisse.
• – Ein durchgängiger Reinraum von der Sterilisation der Vorformlinge vor der Umformungseinrichtung bis zum Verschließer mit zusätzlicher Sterilisation der umgeformten Behältnisse vor und/oder in und/oder nach der Etikettiermaschine
• – Ein durchgängiger Reinraum vom Bereich vor der Etikettiermaschine bis zum Verschließer, eine Sterilisation der umgeformten Behältnisse erfolgt in diesem Bereich und evtl. zusätzlich in oder nach der Etikettiermaschine
• – Ein durchgängiger Reinraum von der Etikettiermaschine bis zum Verschließer bei einer Sterilisation der umgeformten Behältnisse in der Etikettiermaschine

It should be mentioned that a sterilization of the containers does not necessarily, as already mentioned above, must take place before the forming device. A clean room according to the invention in the labeling machine can also be used if a preform manufacturing device, that is, for example, an injection molding machine, is also present in front of the forming device. By present in the preform during injection molding heat already a certain sterility of the containers may be present, which, if a clean room is available continuously until the containers are closed, can be maintained. In this case, the following variants are conceivable, wherein the order of the machines forming device, labeller and then the filling device with associated capper for the container is always maintained (this is no Clean room in front of the former machine in the clean room provided in the following list):

• - A continuous clean room from an upstream injection molding machine to the capper, in this case there is no further sterilization of the containers.
• - A continuous clean room from an upstream injection molding machine to the capper, sterilization of the plastic preforms takes place before their transformation and no further sterilization.
• - A continuous clean room from an upstream injection molding machine to the capper, the sterilization of the formed containers takes place before and / or in and / or after the labeling machine.
• - A continuous clean room from the sterilization of the preforms before the forming device to the capper, there is no sterilization of the formed containers.
• - A continuous clean room from the sterilization of the preforms before the forming device to the capper with additional sterilization of the formed containers before and / or in and / or after the labeling machine
• - A continuous clean room from the area in front of the labeling machine to the capper, a sterilization of the transformed containers takes place in this area and possibly additionally in or after the labeling machine
• - A continuous clean room from the labeling machine to the capper in a sterilization of the transformed containers in the labeling machine

Especially the last two variants would also offer glass bottles. For sterilization (s), all variants or combinations suggested above are suitable.

The present invention is further directed to a method for labeling containers, wherein the containers are transported by means of a transport device along a predetermined transport path and wherein an application unit attaches label material during the transport of the containers to the containers.

According to the invention, the containers are at least temporarily transported during the application of labels within a clean room, said clean room at least partially surrounds the transport path of the containers.

In an advantageous method, the containers are also rotated at least temporarily during the labeling process about a longitudinal axis of the containers.

The applicant further reserves the right to claim protection for a method for labeling containers, in which the containers are transported by means of a transport device along a predetermined transport path and wherein an application unit attaches label material to the containers during the transport of the containers and wherein the containers after be filled with a liquid during the labeling process.

According to the invention, the containers are filled within a clean room which surrounds the transport path of the containers during their filling and the containers are subjected to radiation after labeling and before filling, this radiation having at least radiation components in the ultraviolet spectral range.

In this proposed method, the sterile room does not necessarily have to start in the labeling machine, but can also begin, for example, only in the region of a filling device.

It is proposed here that after the labeling, the containers are driven, for example, through a UV tunnel and irradiated with ultraviolet light. In this way it can be achieved that those parts of the label are adhered to which the UV light passes. It is therefore advantageous to use a UV-curable label size as label size. In the case of printing, the UV light can also be used to cure the printing ink.

Subsequently, the containers are filled within a clean room filler. If, as proposed, the clean room begins later, that is to say in the region of the filling device, the containers are advantageously also sterilized before filling by means of a sterilizer. However, it would also be possible here for the clean room to begin before the labeling machine, as suggested above.

Particularly preferred as label materials so-called stretch sleeves are used, these are preferably used without adhesive. It would also be possible to provide such stretch sleeves in the labeling and after the filler. In this case, however, the transport of the containers is advantageously converted from a neck transport to a ground transport (basehandling). It would also be possible to use pre-glued wrap-around labels as label material or else self-adhesive labels which have initial and end gluing.

In a further advantageous method, the labeling device and the subsequent filler are operated in a block mode, that is to say in particular synchronously.

In particular, it is envisaged not to change the distance between the individual containers from the labeling machine to the filling device, in other words it remains constant. From the filling device to the capper, however, it can be changed or it remains constant here as well.

1 shows a schematic representation of a device 1 for labeling containers 10 , It should be noted that structurally identical or similar features are not described several times in the individual figures. It should also be pointed out that features from different figures can also be combined with one another, as far as is technically feasible. Specifically, aspirations, vents and / or slopes for the drainage of cleaning media / sterilization media in all embodiments at any meaningful position conceivable.

In the 1 shown device 1 for labeling containers 10 has a carrier 2 on, the here also a transport device for transporting the containers 10 represents. The containers are transported on a circular path here, which extends perpendicular to the plane of the figure here. The reference number 12 refers to a drive device such as an electric motor, the transport device 2 , that is, here the carrier designed as rotatable plates, drives. The reference number 72 indicates accordingly a drive shaft for driving in its entirety with 2 designated transport device. The reference numerals 74 and 76 Mark here two rotatable plates, the rotation on the driven shaft 72 are arranged. The reference character D indicates the axis of rotation about which the transport device 2 rotates. Instead of the plates 74 or 76 could also with each other a thinner sheet or ring connected struts to connect the drive shaft 72 be used with the treatment stations.

The reference number 20 refers to a clean room within which the containers are transported. This clean room 20 is thereby also by the two transport plates 74 and 76 educated. The reference number 26 indicates another boundary wall of this clean room 20 , Also this boundary wall 26 turns with the containers. At the transport device, more precisely here at the lower plate 76 , is a variety of drive equipment 14 arranged (here only one represented), in each case over a wave 64 the turntables 68 inside the clean room 20 drive. On these turntables are the containers 10 arranged and thus can rotate about its longitudinal direction L. The rotatable plates simultaneously form upper and lower boundaries of the clean room 20 ,

The reference number 18 indicates another drive, which is a shaft 62 (to Hubbewegungen) drives, which is also the container 10 from above. This is the container between the turntable 18 and the upper holding member 65 , which also turns, clamped. The movable boundary wall is advantageously at least partially cylindrical.

Preferably, however, it is the drive 18 to a lifting drive, a lifting and lowering of the retaining element 65 in the longitudinal direction L of the container allows. The reference number 56 indicates a bellows that seals this longitudinal movement, so that the clean room can not be polluted. The reference number 58 refers to a bearing device for rotatably supporting the shaft 62 ,

The clean room 20 is with two sealing devices 54a . 54b sealed against the environment. These sealing devices are so-called water locks, that is, these have a circumferential stationary channel which is filled with a liquid. In each case swords or sections dive into this liquid 55a . 55b One, dealing with the carriers 74 and 76 rotate. In this way, a seal of the clean room 20 allows.

Via a fine filter unit (FFU) 30 is in the clean room 20 supplied sterile air, so that it is compared to the environment U under an overpressure.

The reference number 4 refers to an application device which the labels (not shown) on the containers 10 install. In this embodiment, this application device 4 arranged stationary and has a (outside the clean room 20 arranged) drive 16 up, a wave 66 to rotate drives. The reference number 42 indicates an application element which attaches the label to the container. It can be seen that a (rotatable) carrier 45 this application device 4 through the opening 35 in the wall 28 in the clean room 20 protrudes. Advantageously, therefore, the size of this opening is chosen as small as possible, so that the carrier 45 just into it can be led into. Furthermore, lock devices can also be provided to this area of the opening 35 seal. On the other hand, sealing means, such as sliding seals could be provided. The wall 28 is arranged stationary. Advantageously, the distance of the container 10 to the wall 28 chosen as small as possible to the opening 35 to keep small in the direction perpendicular to the image plane. In particular, the distance is less than 20 cm, preferably less than 10 cm.

The reference number 52 indicates an optional hydraulic seal for the movement of the turntable 68 , In this case, the area B would be below the turntable and above the rotatable plate 76 no sterile or clean room anymore. A correspondingly rotatable and with the turntable 68 connected section 53 dives into the channel of the sealing device 52 one.

Advantageously, these individual hydraulic sealing devices 52 . 54a . 54b Level controls, which control a level of the liquid medium in the channels and also regulate (refill if necessary).

The transport path of the containers 10 extends perpendicular to the plane of the figure, more precisely along a circular path, which is perpendicular to the plane of the figure here.

2 shows a further embodiment of a device according to the invention for labeling containers. Here is a label magazine 44 shown what about a pallet carousel 46 with a glue roller 46a the individual labels 50 supplies. The reference number 34 indicates a first sterilization station, which sterilizes the labels to be arranged on the containers on the side, which then forms part of the outer surface of the labeled containers. The reference number 32 identifies another (optional) such sterilization station which is the other side of the labels 50 sterilized, which adheres to the container. With appropriate gluing is the sterilizing 32 not absolutely necessary. This can be a sterilization station, which acts on the labels, for example, with hydrogen peroxide or another sterilization medium. In addition, however, it would also be possible for a sterilization with radiation, for example electron radiation or also UV radiation, to take place here.

The transport device 2 serves here again to transport the containers. These containers are delivered via a feed wheel 82 fed and via a Abführrad 84 dissipated, so that the overall outlined by the arrows P transport path into the device 1 into or out of the device 1 results out. The reference number 20 again indicates the clean room, here by the stationary walls shown only schematically 28 is delimited. Sterilization of the gripper cylinder and the pallets is also possible in the embodiment described here (in particular when idling or through further sterilization stations on the non-label-carrying side). In the embodiment shown is the limit 28 of the clean room 20 through the pallet carousel 46 placed at the above corresponding glue choice could be the glue roller 46a and the whole pallet carousel 46 also in the clean room 20 be arranged.

3 shows a further embodiment of in 1 shown device. In this embodiment, the FFU 30 stationary, that is on the stationary wall 28 arranged. Alternatively or additionally, however, it would also be possible to have a FFU 30 (dashed lines) on the rotating part of the system, here on the upper plate 74 to arrange.

4 shows a further embodiment of a labeling device. In this case, a total of 4 designated application unit arranged such that it has a coupling element 41 at the transport device 2 or at the stationary parts of the transport device 2 can be coupled or docked. The label material 100 (which is band-like here) can be the clean room here 20 again via an opening 33 be supplied. In this case, a wall section which is stationary in the direction of rotation is preferably provided 28a in the height direction H movable so as to achieve an adaptation to the label size and preferably to provide a positionable opening at the unit change. Also in this embodiment is the turntable 68 again with hydraulic seals 52 sealed. The reference number 59 identifies wheels that facilitate the mobility of the application device 4 enable. The FFU is here again at the rotating part, that is here at the top plate 74 arranged. However, it would also be conceivable, for example, this FFU from below on the lower plate 76 to arrange. Furthermore, the coupling element 41 the machine with a drive for lifting the application unit 4 be coupled. The (self-adhesive) labels are off the line 100 by means of the dispensing edge 42 replaced. The opening 33 is in this case only a perpendicular to the image plane extending thin slot.

The reference number 270 indicates a (preferably outside the clean room arranged) cutting unit to separate the individual sleeves or sheaths. The reference number 278 indicates a wall, which in the dipping bath 264 protrudes and in this way also the clean room 20 separates. The clean room 20 is therefore also here by this wall 278 limited, so that here, too, an effective sealing of a clean room is possible. In particular, the wall is 278 with the radially outer wall ( 28 ) or the wall 278 dives from the ceiling in an annular manner - enclosing the sleeve - into the immersion bath (not shown). In this way, a completely tight barrier for air is achieved. The reference number 102 refers again to a suction device for sucking H ₂ O ₂ .

Furthermore, a variety of roles 282 . 284 (partly outside the dipping bath 264 , partly within the dipping bath 264 ) intended. These rollers support the sleeve 260 opposite the sleeve mandrel 262 and also serve to transport the sleeves. Further, drive means (not shown) for driving these rollers 282 . 284 intended. These drive devices can be inside and / or outside the clean room 20 be arranged.

15 also illustrates a labeling of the containers with sleeves. Here, in this embodiment, again a reservoir 35 for supplying a sterilization medium via a supply line 126 intended. In this embodiment, the container with a holding device 294 gripped from underneath and the sleeves are again pulled over the containers. It is also possible that after donating the sleeves on the container 10 the sleeve can be shrunk with a sterilizing agent, for example with hot H ₂ O ₂ gas. In this case, the gas sterilizes the container 10 as well as the sleeve both inside and outside. The mandrel shown here is offset here in the direction of rotation of the machine and is arranged stationary, as can be seen from the arrangement of the sealing device 54b results. In this way, the in 15 shown machine used advantageously only in clock mode.

16 shows a similar embodiment as 15 However, this system is suitable for continuous operation. Note the changed arrangement of the sealing device 54b , In this embodiment, the mandrel moves with the container 10 With.

17 shows a further embodiment for the sleeve labeling. Again, a continuously running machine is preferably provided as well as fixed nozzles 299 that are not in the transport path of the containers 10 stand. These nozzles act on the container with the sleeve arranged thereon (eg with H ₂ O ₂ ) and shrink it in this way. It would also be conceivable to use a sterilization medium which does not shrink the sleeves and apply the containers still in the machine or afterwards with (sterile) hot air in order to shrink the sleeves.

18a and 18b show an example of labels to be attached 300 , In this case, the reference numeral refers 302 on a label imprint and the reference numeral 304 on a non-printed area, such as an area for the initial and final taping in the case of a wrap-around label of a roll. However, this is also conceivable when using corresponding pallets in the case of individual labels. The label 300 Here is a transparent label, which the said imprint 302 having. At the label in 18b are more imprinted parts 312 still outside the unprinted area 304 intended. This in 18a and 18b The labels shown are particularly suitable for the following method. First, the containers are provided, then a regionally particular UV and translucent label 300 applied with adhesive, wherein the adhesive in particular at the non-printed locations of the label 300 located. Subsequently, the label is exposed to UV light to achieve curing of the adhesive. Furthermore, the container and the label can be sterilized by means of UV light. However, sterilization procedures can also be carried out in other ways.

19 shows a possible embodiment of a system 400 for treating containers. In this case, the reference numeral refers 402 to an oven or heater for heating plastic preforms. These plastic preforms are starting from a reservoir, such as a chute 404 , fed. Subsequently, the plastic preforms to a in its entirety with 410 designated Blasmodul, in particular a stretch blow molding machine supplied and formed there to the plastic bottles or plastic containers. Optionally, this can also be a sterilization module 408 be provided or a module 408 , which allows a varying in the circumferential direction heating, in particular for producing non-circular, for example, oval, containers. The reference numerals 406 . 412 . 414 and 416 refer in each case to transfer stars, which pass the manufactured containers. The reference number 1 indicates in its entirety the labeling device as described above. In this case, the reference numerals relate 4 to the respective labeling units and the reference numerals 422 each on UV light waves for sterilizing and / or curing of glue.

Downstream of the labeling device, a rinsing module closes 420 which is optional and then a filling device 430 , The reference number 440 indicates a closure device. Subsequently, the containers are carried out and a packer 450 For example, to a palletizer 460 guided. The reference number 20 again identifies the clean room, as seen here from the labeling 1 starts. In addition, it would be possible to expand the clean room, for example, if preforms already after the heater 402 be sterilized. It would also be possible, the clean room area on the heating device 402 expand, for example, if sterilization in or directly in front of the oven 402 he follows. This is illustrated by the dashed lines.

20 shows a further embodiment of a system according to the invention, in which case also here, as in the case of 19 , a heating unit 402 as well as a blowing machine 410 are provided. The labeling device 1 however, it is used here for attaching sleeve labels to the containers. At this labeling closes here a shrink tunnel 425 on, the heating elements 426 has, which shrink the labels on the containers. However, it would also be conceivable to sterilize the sleeve together with the container before the container in the shrink tunnel 425 moves, since in this design, the sterilization medium also gets into the area between the sleeve and the container. If sealing of the (sleeve) label to the containers is ensured, it is also possible to sterilize the containers, including the label already applied, without sterilizing the inside of the labels or the area covered with the labels on the bottles got to.

In 21 is a one-step process illustrated, here over a manufacturing unit 470 the plastic preforms are produced, then with a blow molding machine 410 be blown and then the labeling process, as described above with reference to 19 and 20 described. Instead of the solutions for container production shown here, it is also intended to produce containers by means of extrusion blow molding or injection blow molding.

The 22a to 23 illustrate embodiments for a vacuum or gripper cylinder 45 as an example of an application device 4 , At the in 22a shown embodiment, a geometric axis of a shaft of the vacuum cylinder simultaneously forms a boundary G of the clean room. This is the wave 66 of the vacuum cylinder half in the clean room 20 , At the in 22b The embodiment shown is the shaft 66 of the vacuum cylinder 45 completely outside the clean room. 23 shows a sectional view of a vacuum cylinder after 22b , It can be seen that the vacuum cylinder 45 here a circumferential sealing device 508 having, which the opening area of the wall 28 as far as possible seals. This is here except for the passage window for the labels 50 a perfect seal proposed by the clean room outgoing side. Inside the vacuum cylinder 45 there are channels here 502 . 504 showing the vacuum for the label material 25 provide. The reference number 506 indicates a vacuum pump.

The reference number 508 indicates a sealing device, which surrounds the vacuum or gripper cylinder here in full circumference. This sealing device 508 can be in a recess of the wall 28 through which the vacuum cylinder 45 be arranged protruding. In this case, this sealing device 508 to the direction of movement of the vacuum cylinder 45 be adapted and, for example, on the side with respect to the axis of rotation of the vacuum cylinder 45 (on which the label is also located), in the clean room 20 be directed in and extend on the other side with respect to the axis of rotation to the outside. This sealing device 508 may be formed of an elastic material (eg a rubber material) and on an outer circumference of the vacuum cylinder 45 invest. In the area in which the label rests against the vacuum cylinder, the sealing device could 508 have a recess.

The 24 shows two more illustrations to illustrate the sealing of the vacuum cylinder. In this design is an additional role 518 provided, which opposite the vacuum cylinder 45 unwinds around the gap that is facing the wall 28 yields, seals. This role rolls against the vacuum cylinder 45 or with respect to its outer surface and preferably also with respect to the label 50 from.

Furthermore, a biasing device 520 be provided, which is the additional role 518 opposite the vacuum cylinder 45 biases. This biasing device can be applied to a sealing portion 514 acting outside the role 518 is arranged. The reference number 516 marks a wave opposite the roll 518 is rotatably mounted.

The pretensioner 520 or another biasing device could also act on this wave. The reference number 522 indicates a (in particular stationary) bearing point. This pushes the role 518 in addition, the label on the vacuum cylinder.

On the opposite side of the vacuum cylinder, unlike in the 24 be shown another role arranged. This further role can in particular also to protect the outer surface of the vacuum cylinder 45 serve, since these are then not directly opposite the wall 28 must be sealed. Also can about the role 518 a sterilant is applied to the label.
