Description

[0001] Container treatment plant

[0002] Technical area

[0003] The invention relates to a plant for treating, in particular combined manufacturing, labelling and filling, containers, in particular PET bottles.

[0004] State of the art

[0005] Devices, particularly in block form, for producing, labeling, and filling liquid products into containers, especially bottles, are generally known. Such devices are described, for example, in DE 10 2006 053 193 A1 or DE 43 26601 A1.

[0006] The production of containers, especially PET (polyethylene terephthalate) bottles, is typically carried out by blow molding. Preheated preforms are processed under heat to form containers or bottles. Containers leaving the blow molding machine in a hot state cannot be filled directly. Instead, they must be cooled and stabilized immediately after production by cooling measures, at least to the point where they can be filled with a liquid product. Since the liquid product often contains carbon dioxide and is filled under pressure, increased demands are placed on the mechanical stability of the PET containers produced directly beforehand.The problem is compounded when using labeling devices that are located upstream of the filling machine and that apply an internal pressure, the so-called stabilization pressure, to the containers during labeling. To achieve sufficient cooling of the produced containers, it is known to spray the containers externally with a cooling medium. Such a method and device are known, for example, from EP 2 956 288 B1. There, a liquid cooling medium mixed with a disinfectant is sprayed onto the produced containers.

[0007] However, with the state-of-the-art devices, the manufactured containers are still not sufficiently cooled, especially before labeling. After filling, stress cracks develop in the containers, particularly due to the pressure or pre-stress of the CO2-containing products. Containers affected by such stress cracks often only lose their contents after they have already been palletized and stored, thus contaminating the inventory.

[0008] Description of the invention

[0009] The invention is therefore based on the object of providing a system for treating containers that eliminates the above-mentioned problems and disadvantages of the prior art. In particular, the object of the invention is to provide a system that results in fewer or no leaky containers.

[0010] This object is solved by the subject matter of independent claim 1. Further possible embodiments of the invention are specified in particular in the dependent claims.

[0011] The solution according to the invention consists in particular in specifying a system for treating, in particular combined manufacturing, labeling and preferably filling, containers, in particular PET bottles. The system has a blow molding machine for manufacturing containers. The blow molding machine is therefore designed to manufacture containers. The system also has a labeling device for labeling the containers manufactured by means of the blow molding machine. The labeling device is therefore designed to label containers, i.e. to provide them with labels. Furthermore, the system has a cooling device for cooling the manufactured containers. The cooling device is therefore designed to cool the manufactured containers. The cooling device has a cooling section. A plurality of outlet openings, in particular nozzles, are arranged along the cooling section.The outlet openings are used to supply the containers with a cooling medium.

[0012] According to the invention, a gas or gas mixture, in particular air, is used as the cooling medium, and the cooling section extends into the labeling device. In particular, outlet openings are also arranged within the labeling device.

[0013] Containers are generally formed as a single piece or from several parts that are firmly connected to one another. Each container preferably has a hollow space inside. The walls that define this hollow space are the inner walls of the container. The container is designed to separate the formed hollow space from the surroundings. The container can, for example, be a container for storing food and in particular liquid products. The containers are particularly preferably bottles. The following descriptions are therefore often based on bottles as an example. Of course, the aspects described there can also be extended to other types of containers. The bottles are, in particular, PET bottles. In general, bottles have a bottle mouth or bottle opening in an upper region. The bottle mouth is used to fill the bottles and can be closed after filling.

[0014] The blow molding machine is designed for blow molding containers. In blow molding, the containers are manufactured from preforms. Typically, the mouth of the preform already has its final shape. Blow molding can involve extrusion blow molding, in which the container is formed from a tube of hot, moldable plastic. This is done by ejecting or extruding the tube vertically downward into a corresponding workpiece.

[0015] However, blow molding is preferably stretch blow molding. In stretch blow molding, the preform is heated, held in a cavity, and enclosed within it. A mandrel then enters the preform from above, and compressed air is forced into the preform, inflating it and pressing it against the contours of the blow molding tool or cavity. This allows the desired shape of a plastic bottle to be defined.

[0016] Empty containers, especially bottles, produced by blow molding under heat typically have a temperature above 70 °C immediately after production. Typical temperatures are between 75 °C and 80 °C, but in some cases temperatures can reach up to 90 °C.

[0017] Before applying pressure to the containers, especially before labeling and filling, the containers must be cooled to a temperature at which the thermoplastic material used for the containers has sufficient stability. For example, the containers must be cooled to 60 °C or lower.

[0018] Only when the containers have been cooled to a temperature at which they are sufficiently stable can it be guaranteed that they will not develop stress cracks later. Such stress cracks often only appear after filling and pressurization, when the containers are palletized and stored. As a result, containers affected by stress cracks lose their contents and contaminate the remaining inventory. In principle, it would also be conceivable to cool the containers to a different specified temperature during cooling to prevent negative effects, such as the condensation of H2O2, in downstream treatments.

[0019] The cooling section is generally the section of the cooling device along which the containers are cooled. The cooling section can, for example, be a pipe or pipe system arranged following the container transport flow. The pipe or pipe system then has a plurality of outlet openings through which the cooling medium can flow out of the pipe or pipe system. The outlet openings are therefore openings in the cooling section or in the pipe or pipe system that serve to direct the cooling medium onto the containers in order to cool them. In particular, the outlet openings are designed as nozzles. This allows for a particularly good flow of cooling medium.

[0020] Previously, fluids or aerosols were typically used as cooling media. However, since the labeling device is a dry area, the cooling section is only located upstream and downstream of the labeling device. Thus, the containers were cooled downstream of the labeling device on a transfer line from the blow molding machine to the labeling device and downstream of the labeling device.

[0021] According to the invention, however, the cooling section with the outlet openings extends into the labeling device. Accordingly, the containers are cooled by applying a cooling medium in the labeling device, so that the transfer distance between the blow molding machine and the labeling device can be shortened. Gas or a gas mixture, in particular air, is also used as the cooling medium. This makes it possible to provide a dry cooling medium, the use of which is possible within the labeling device without negatively impacting the labeling process. If conventional cooling media with a high degree of moisture were used within the labeling device, the labeling process in the labeling device would be disrupted. The cooling medium is particularly preferably dry air.

[0022] The invention is therefore based on the finding that by changing the cooling medium to a gas or gas mixture, in particular air, it is possible to extend the cooling section far into the labeling device.

[0023] According to an advantageous development of the invention, the labeling device comprises a labeling carousel. The cooling section and, in particular, the outlet openings are formed at least partially along the labeling carousel.

[0024] Preferably, the cooling section along the labeling carousel is curved, at least in some areas. The cooling section thus follows the container transport flow or transport path defined by the labeling carousel. In particular, the cooling section is curved, at least along 90°, preferably at least 125°, and particularly preferably at least 180°, along the labeling carousel.

[0025] Overall, this allows a long and therefore effective cooling section to be created within the labeling device.

[0026] The labeling device can further comprise an input starwheel into the labeling carousel and an output starwheel from the labeling carousel. Particularly preferably, the cooling section also extends at least partially along the input starwheel. Particularly preferably, the cooling section extends continuously between the input starwheel and the labeling carousel. The cooling section is thus formed, for example, by a continuous pipe or pipe system.

[0027] In an advantageous development, the labeling device comprises a labeling unit. The labeling unit is the part of the labeling device designed to apply a label to the container. The labeling unit is preferably arranged on the labeling carousel. For example, the cooling section, in particular its outlet openings, is arranged upstream of the labeling unit in the container transport stream.

[0028] Particularly preferably, the cooling section, in particular the outlet openings, extends to just before the labeling unit. In other words, the cooling section extends at least substantially to the labeling unit.

[0029] According to an advantageous development of the invention, the cooling section, in particular the outlet openings, are arranged in the container transport stream upstream and downstream of the labeling unit. In particular, the cooling section or the outlet openings are arranged on the labeling carousel upstream and downstream of the labeling unit.

[0030] Here too, the cooling section preferably extends at least substantially to the labelling unit.

[0031] If the cooling section is arranged before and after the labeling unit within the labeling device, particularly along the labeling carousel, particularly effective container cooling can be achieved. For example, such a cooling section is used for large-volume containers with a volume of over one liter, preferably 2.5 liters. For small-volume containers with a volume of 0.5 liters, it may be sufficient if the cooling section is arranged only before the labeling unit.

[0032] Preferably, the cooling section is arranged upstream and downstream of the labeling unit if the containers used are large-volume, and the cooling section is arranged exclusively upstream of the labeling unit if the containers used are small-volume. In an advantageous development of the invention, the cooling section in the region of the labeling unit is designed without outlet openings or has closed outlet openings.

[0033] This means that no cooling medium is discharged in the vicinity of the labeling unit. The cooling section can still be continuous, i.e., formed from a pipe or pipe system. In this case, the cooling section also runs, for example, below the labeling unit, but has no or closed outlet openings there. Alternatively, a cooling section without outlet openings can also be formed using an interrupted cooling section. In this case, the cooling section does not run continuously along, especially below, the labeling unit, but has an interruption at this point.

[0034] Alternatively, it would also be conceivable for the cooling section to have open outlet openings in the area of ​​the labeling unit. In this case, the outlet openings are preferably designed and / or aligned in such a way that these or the generated cooling medium flows do not impair the function of the labeling unit.

[0035] According to an advantageous development of the invention, air flow protection devices, in particular shielding plates, are arranged between the outlet openings before and / or after the labeling unit and the labeling unit.

[0036] Alternatively or additionally, in a further embodiment of the invention, the outlet openings, in particular nozzles, are aligned and arranged such that the outlet openings generate cooling medium flows directed away from a labeling area of ​​the labeling unit. The labeling area is preferably the area of ​​the labeling unit where the labels are transferred to the containers.

[0037] The two options described serve to protect the labeling unit from impairing cooling medium flows. In simple terms, both the airflow protection devices and the specific alignment and arrangement of the outlet openings prevent labels from being blown onto the labeling unit during labeling, which could cause them to slip or shift. These two measures therefore ensure trouble-free labeling and allow the cooling line to be positioned close to the labeling unit.

[0038] In an advantageous development of the invention, the labeling device comprises holding elements for holding the containers at a mouth region, i.e., the container mouth. The holding elements are preferably designed to rotate the containers about a vertical axis of the containers.

[0039] Since the holding elements are designed to hold the containers at a mouth area, the containers are held from above. Particularly preferably, the holding elements are designed to hold bottles by the bottle neck. This allows access to the container or bottle base. In particular, this allows for container base cooling or

[0040] Bottle bottom cooling can be implemented as a cooling device.

[0041] The containers can be rotated, for example, using a stamp and is used to rotate the containers around their vertical axis during labeling.

[0042] With a labeling device designed in this way, cooling of the container base is possible. Containers, especially bottles, often have very thick material at the base. Through the measures described above, the invention takes into account the fact that these areas of thick material require special cooling, because otherwise, temperature peaks would occur in these areas due to the accumulation of plastic there and its poor thermal conductivity, which would promote cracking.

[0043] In an advantageous development of the invention, the labeling device is designed to apply a stabilizing pressure of more than 0.2 bar, preferably more than 0.25 bar, particularly preferably approximately 0.3 bar, to the containers. In particular, a stabilizing pressure of up to 3.5 bar is conceivable.

[0044] Stabilization pressure is an internal pressure applied to the containers to stabilize them during labeling. A sufficiently high stabilization pressure is necessary for reliable and accurate labeling. On the other hand, high stabilization pressure on containers that have not yet cooled sufficiently can cause damage to the container, particularly cracking.

[0045] However, since the cooling system extends into the labeling device, a sufficiently long cooling zone is provided, allowing the containers to be sufficiently cooled. This allows the containers to be subjected to the advantageous stabilizing pressure shortly after production. This enables high-quality labeling on intact containers.

[0046] In an advantageous development of the invention, the cooling device is designed as a container bottom cooling device or a bottle bottom cooling device. The outlet openings are then preferably arranged below the containers.

[0047] The containers are therefore cooled from below, so that most of the cooling medium comes into contact with the bottle bottom. As already described, the bottle bottom is a sensitive area that requires particularly high levels of cooling. Bottle bottom cooling or general container bottom cooling, especially in combination with the previously described holding elements, allows for targeted cooling of the bottle bottom.

[0048] Alternatively or additionally, it would also be conceivable for outlet openings to be arranged laterally around the bottle or the bottle base. According to an advantageous development of the invention, the

[0049] Cooling device has a heat exchanger to cool the cooling medium.

[0050] The heat exchanger preferably has a liquid heat transfer medium. This allows the cooling medium to be sufficiently cooled.

[0051] According to an advantageous development of the invention, the system comprises a filling machine. Preferably, the system comprises a further cooling device arranged in the container transport flow upstream of the filling machine, in particular between the filling machine and the labeling device. Preferably, the further cooling device is designed as a fluid cooling system. Alternatively, the cooling device is also designed as a dry cooling system using a gas or a gas mixture.

[0052] The additional cooling device allows the container to be cooled even further before entering the filling machine. For example, the containers should be cooled to a maximum of 55 °C before being subjected to filling pressure during filling. The filling pressure is higher than the stabilization pressure during labeling.

[0053] As an alternative to a filling machine, it would also be conceivable for the system to include a coating machine, in particular a Plasmax coating machine. The Plasmax coating machine is designed to coat the inside of the container with a thin protective layer of glass or SiO x to cover.

[0054] According to an advantageous development of the invention, the blow molding machine, the labeling machine, the filling machine, and the cooling device are designed as a single unit. Consequently, the system is designed as a combination machine.

[0055] It has proven particularly advantageous when container production, container labeling, and container filling take place directly after one another, i.e., combined production, labeling, and filling. This is achieved by combining the individual machines into a single unit in a block design. Overall, this provides a space-saving and cost-effective design. Furthermore, cleaning procedures are eliminated, which are necessary when longer transport routes or storage of the manufactured containers are required after production and before filling.

[0056] Particularly in such combination machines, particularly effective and sufficient container cooling is necessary and important. The invention also has a positive effect here, as the transfer line between the blow molding machine and the labeling machine can be eliminated or at least shortened, thus further reducing the size of the machine.

[0057] In principle, when using a coating machine, it would also be conceivable for the blow molding machine, the labeling machine, the coating machine and the cooling device to be designed as a single structural unit.

[0058] In general, the present invention is always applicable when a labeling or labeling device is provided in combination with a tempering device or cooling device for bottles.

[0059] Short description of the drawings

[0060] The various and exemplary features described above can be combined with one another according to the invention, provided this is technically reasonable and suitable. Further features, advantages, and embodiments of the invention will become apparent from the following description of exemplary embodiments and from the figures.

[0061] The figures used to explain the embodiments show:

[0062] Fig. 1 is a schematic representation of the system according to the invention; and Fig. 2 is a more detailed view of a labeling device usable in the system in Fig. 1.

[0063] Ways to implement the invention

[0064] Fig. 1 shows a system 100 for treating, in particular combined manufacturing, labeling and filling, containers 10 designed as bottles 10. Since the containers 10 are bottles 10, the following embodiments are described directly with reference to bottles 10.

[0065] To produce the bottles 10, the system 100 includes a blow molding machine 110. After their production, the bottles 10 are transferred from the blow molding machine 110 to a labeling device 120 of the system 100. In the labeling device 120, the bottles 10 are provided with a label. For this purpose, the labeling device 120 includes a labeling unit 122 designed to apply the labels to the bottles 10.

[0066] After labeling, the containers 10 are transferred via conveyor belts 151 to a filling machine 140 of the system 100. In the filling machine 140, the bottles 10 are filled with a filling material, in particular containing carbon dioxide, and sealed.

[0067] The system 100 shown in Fig. 1 is designed as a combination machine to carry out both the production, labeling and filling of the bottles 10.

[0068] The empty bottles 10 produced by blow molding with heating typically have a temperature of at least 70°C, often 75°C to 80°C, at the exit of the blow molding machine 110. This means that, before further processing, the bottles 10 must be cooled to a temperature at which the thermoplastic used for the bottles 10 has sufficient stability. For example, a temperature of 60°C or lower must be reached for this purpose.

[0069] For this purpose, the system 100 has a cooling device 130 for cooling the produced bottles 10. The cooling device 130 has a cooling section 131, which, as can be seen in Fig. 1, also extends within the labeling device 120.

[0070] In addition to the cooling device 130, the system 100 may have a further cooling device 150 located between the labeling device 120 and the filling machine 140.

[0071] Fig. 2 shows a more detailed view of the labeling device 120 and the cooling device 130 arranged therein.

[0072] The labeling device 120 has an input starwheel 124, a labeling carousel 121, and an output starwheel 125. The input starwheel 124 is designed to transfer bottles 10 to the labeling carousel 121. In the labeling carousel 121, the bottles 10 are transported in a circular motion past the labeling unit 122 to the output starwheel 125. The labeling unit 122 is designed to apply a label to the bottles 10 transported past. The labeling unit 122 is shown in Fig. 2 in a simplified manner as a box to ensure clear visibility of the cooling device 130.

[0073] The exit starwheel 125 is preferably designed as a pitch-delay starwheel. The exit starwheel 125 then serves not only to transport the bottles 10 from the labeling device 120, but also to change the pitch of the bottles 10.

[0074] The labeling carousel 121 has a plurality of holding elements 123, shown only sketchily, for holding the bottles 10 at a bottle mouth 11. The bottles 10 are thus held in an upper area of ​​the labeling carousel 121. Although this is not visible in Fig. 2, the holding elements 123 are designed to rotate the bottles 10 about a vertical axis. The bottles 10 are rotated upon reaching the labeling unit 122 in order to apply the label circumferentially.

[0075] As can be seen in Fig. 2, the cooling section 131 has a plurality of outlet openings 132 through which the cooling medium can exit. Only a few outlet openings 132 are shown in Fig. 2 as examples. However, the outlet openings 132 can extend completely along the cooling section 131. The plurality of outlet openings 132 are preferably designed as nozzles to direct the cooling medium specifically onto the bottles 10.

[0076] As can also be seen in Fig. 2, the cooling section 131 comprises several sections. In particular, the cooling section 131 has an inlet star cooling section 131c, which is arranged at the inlet star 124. The inlet star cooling section 131c follows the bottle transport flow at the inlet star 124, thus being at least substantially curved.

[0077] Furthermore, the cooling section 131 has a front cooling section 131a. The front cooling section 131a is arranged in a front region of the labeling carousel 121, as seen in the bottle transport flow. The front cooling section 131a extends to the labeling unit 122. Independently of this, the front cooling section 131a follows the bottle transport flow or transport path defined by the labeling carousel 121. The front cooling section 131a is thus at least substantially arcuate or partially circular.

[0078] Between the inlet cooling section 131c and the front cooling section 131a, a turning point is located at which the path of the cooling section 131 transitions from a left turn to a right turn. Irrespective of this, the front cooling section 131a and the inlet cooling section 131c can be formed continuously from a common pipe or pipe system, as shown in Fig. 2, with the cooling medium flowing from the inlet cooling section 131c into the front cooling section 131a or vice versa. The front cooling section 131a and the inlet cooling section 131c are thus fluidically connected.

[0079] The cooling section 131 further comprises a rear cooling section 131b. The rear cooling section 131b is arranged in a rear region of the labeling carousel 121, as viewed in the bottle transport flow. In particular, the rear cooling section 131b is arranged behind the labeling unit 122.

[0080] However, the arrangement of the sections of the cooling section 131 shown in Fig. 2 is not to be understood as limiting. For example, only the front cooling section 131a, the front cooling section 131a and the inlet star cooling section 131c, or the front cooling section 131a, the rear cooling section 131b and the inlet star cooling section 131c can be formed. This depends in particular on the type of bottle 10 used. For example, the inlet star cooling section 131c in combination with the front cooling section 131a is sufficient to adequately cool small bottles with a filling volume of 0.5 liters. The rear cooling section 131b is then additionally useful for larger bottles 10 with a larger filling volume of at least one liter, preferably 2.5 liters.

[0081] In Fig. 2, the rear cooling section 131b is formed separately from the front cooling section 131a. There is therefore an interruption between the front cooling section 131a and the rear cooling section 131b. Accordingly, the front cooling section 131a and the rear cooling section 131b have supply inlets 134 formed separately from one another. However, it would also be conceivable for the front cooling section 131a and the rear cooling section 131b to be connected, in particular fluidically connected. In this case, the front cooling section 131a and the rear cooling section 131b would be connected in a similar way to the front cooling section 131a and the inlet star cooling section 131c. If the front cooling section 131a and the rear cooling section 131b are connected to one another, a cooling section 131 is also formed in the region of the labeling unit 122, more precisely below the labeling unit 122.In order not to negatively influence the labeling process, it is then provided that no outlet openings 132 are arranged in this area of ​​the cooling section 131 through which the cooling medium escapes to the outside.

[0082] The labeling device 120 can have further means for protecting the labeling unit 122. For example, the outlet openings 132, which are formed adjacent to the labeling unit 122, can be aligned and arranged such that the cooling medium flow generated by them is directed away from a labeling area of ​​the labeling unit 122. Thus, the cooling medium flow cannot negatively influence the labeling taking place in the labeling area.

[0083] A further protective measure is provided by the air flow protection devices 126 indicated in Fig. 2, which in the form of shielding plates shield the labeling unit 120 from the outlet openings 132.

[0084] As can be seen in Fig. 2, the cooling device 130 is designed as a bottle bottom cooler. The cooling device 130 is designed, in particular, to cool the bottle bottom of the bottles 10. For this purpose, the cooling section 131 is arranged below the bottles 10. The outlet openings 132 are directed upwards along the cooling section 131 and thus toward the containers 10. This ensures effective cooling of the bottles 10. As indicated in Fig. 2, the cooling device 130 has a heat exchanger 133 for providing the cool cooling medium.

[0085] It should be noted that the features of the invention described with reference to individual embodiments or variants, such as the type and design of the individual components as well as their precise dimensions and spatial arrangement, may also be present in other embodiments, unless otherwise stated or technically prohibited. Furthermore, such features of individual embodiments described in combination do not necessarily have to be implemented in a given embodiment.
