Description

Technical field

[0001] The invention relates to a container treatment plant with a cleanroom and a method for operating a container treatment plant with a cleanroom. Technical background

[0002] It is known to treat containers in a container treatment plant, e.g., to manufacture, fill, and seal them. If there are special hygiene requirements for container treatment, the container treatment plant may, for example, include a cleanroom where the treatment of the containers takes place under cleanroom conditions.

[0003] It may be necessary to clean specific components in the cleanroom, such as cameras, optical devices, or sensors. The primary goal is to remove particles from the respective component. These particles can be generated, for example, by abrasion from the container during handling in the cleanroom. The aim of cleaning is to prevent functional impairment or at least to extend the component's lifespan until the next maintenance cycle.

[0004] Cleaning can be carried out, for example, by opening the cleanroom and manually cleaning the respective component, or by using brushes or wipers that specifically touch the section of the respective component that needs to be cleaned.

[0005] A disadvantage of these solutions is that opening the cleanroom interrupts the container treatment for a relatively long period, as a cleanroom environment must first be restored after cleaning and closing the cleanroom. Furthermore, the use of brushes or wipers can cause mechanical damage, such as scratches, to the surface being cleaned.

[0006] It is also possible that components are located in the cleanroom that would benefit from cooling.

[0007] The invention is based on the objective of creating an improved technology for cleaning and / or cooling in the cleanroom of a container treatment plant. Summary of the invention

[0008] The problem is solved by the features of the independent claims. Advantageous further developments are specified in the dependent claims and the description.

[0009] One aspect concerns a container handling system comprising a cleanroom and at least one device (e.g., a rotary conveyor) for transporting and / or treating (e.g., tempering, manufacturing, filling, sealing, and / or outfitting) containers, wherein the at least one device is located in the cleanroom. The container handling system further comprises an air distribution system (e.g., for cleaning and / or cooling) that includes an air inlet located in the cleanroom for receiving cleanroom air from the cleanroom and an air outlet located in the cleanroom for delivering a directed cleanroom airflow (e.g., sterile airflow) for cleaning and / or cooling. The air distribution system further comprises a fluid line connecting the air inlet and the air outlet and an air conveying unit (e.g., a pump).blower or compressor), which is located in the fluid line for drawing in cleanroom air from the air inlet and conveying the drawn-in cleanroom air to the air outlet.

[0010] Advantageously, the device enables targeted cleaning and / or cooling within the cleanroom at a desired location through its directed cleanroom airflow, requiring only minimal construction costs. In contrast to a cleanroom / sterile airflow generated externally, there is no need for extensive structural measures such as sterile filters and long, regularly sterilized piping. The directed cleanroom airflow can preferably be used to blow particles off surfaces, enabling effective and gentle cleaning. Furthermore, the blow-off process is highly scalable without significantly affecting the cleanroom pressure.The proposed technology also has the advantage of not requiring any additional consumption of a relatively expensive medium such as sterile air and is self-sterilizing due to its integration within the cleanroom. The proposed technology can also be used, for example, in non-aseptic applications.

[0011] For example, the at least one device can be a heating device for heating preforms (container blanks or preforms), a container manufacturing device (e.g., a container blow molding machine), a coating device for coating the containers, a depalletizing device, a rinsing device (e.g., with rinse nozzles), a sterilization device (e.g., with sterilization nozzles) for sterilizing the containers, a filling device (e.g., with filling valves) for filling the containers (e.g., with a liquid or pasty material), a closing device (e.g., with closing heads) for closing the containers, a labeling device (e.g., with labeling units) for labeling the containers, a printing device (e.g., with print heads) for printing on the containers, a pasteurizing device for pasteurizing the containers, a glue packaging manufacturing device (e.g., with adhesive application nozzles), a packaging device (e.g.,with packing heads or film wrappers) and / or a palletizing device (e.g. with palletizing heads, sliding plates or the like).

[0012] In one embodiment, the air outlet has a nozzle section for generating the directed cleanroom airflow. Advantageously, this allows the directed cleanroom airflow to be generated reliably and with a narrow flow.

[0013] In another embodiment, the air inlet is designed as a free end of a duct, and / or the air outlet is designed as a free end of a duct. This advantageously allows for a simple design of the air distribution system, as well as direct intake of cleanroom air from the cleanroom and direct discharge of this intake air as a directed cleanroom airflow into the cleanroom.

[0014] In one embodiment, the air outlet is directed horizontally or downwards. This advantageously prevents the directed cleanroom airflow from unintentionally carrying particles upwards within the cleanroom, thus preventing these particles from, for example, reaching and contaminating the container openings.

[0015] In a further embodiment, the air outlet for releasing the directed cleanroom airflow is arranged in a direction towards a component of the container treatment system to be cleaned and / or cooled. The component to be cleaned and / or cooled is located in the cleanroom. Preferably, the air outlet can be arranged adjacent to the component to be cleaned and / or cooled. Alternatively or additionally, the air outlet can be oriented relative to the component to be cleaned and / or cooled such that the directed cleanroom airflow released from the air outlet strikes and / or passes through the component to be cleaned and / or cooled. Advantageously, this allows for cleaning the component to remove particles and / or cooling the component.

[0016] In one embodiment, the component to be cleaned and / or cooled is a sensor device, preferably for detecting the containers, located in the cleanroom. Optionally, the sensor device can be a non-contact and / or optical sensor, preferably comprising at least one camera, an ultrasonic sensor, a laser sensor, a distance sensor, and an LED sensor. Advantageously, the technology proposed herein can be used to clean / blow off particles from the sensor device, thereby increasing and maintaining measurement accuracy / quality without requiring regular opening of the cleanroom for downtime and cleaning. Ultimately, this can advantageously increase the usable operating time of the container treatment system.

[0017] In a further embodiment, the air outlet is arranged such that the directed cleanroom airflow can be released to flow along the containers being treated and / or transported by the at least one device, preferably below a container opening and / or to deflect particles trickling down from the containers (e.g., away from one or more components of the container treatment system to be cleaned and / or cooled, preferably a sensor device). This advantageously prevents particles carried by the directed cleanroom airflow from reaching, for example, the container opening and contaminating it.

[0018] In one embodiment, the air conveying unit is located in the cleanroom, and / or the fluid line runs entirely within the cleanroom. This advantageously allows for a particularly simple design.

[0019] In a further embodiment, the container treatment system also includes a drive unit that is connected to the air conveying unit, with the drive unit being located outside the cleanroom. Preferably, an outer wall of the cleanroom can have a sealed shaft penetration through which a drive shaft passes, connecting the drive unit to the air conveying unit. This advantageously eliminates the need for complex encapsulation of the drive unit when located within the cleanroom. Furthermore, it allows for maintenance of the drive unit outside the cleanroom.

[0020] In one embodiment, the cleanroom can be pressurized and / or pressurized with sterile air. Advantageously, this prevents the ingress of particles, etc., from outside the cleanroom into its interior due to the existing pressure differential.

[0021] In another embodiment, the air inlet, fluid line, air conveying unit, and air outlet are free of sterile air filters and / or sterilizing devices for sterilizing air. Advantageously, this allows the integration of the air inlet, fluid line, air conveying unit, and air outlet within the cleanroom itself to be utilized, since, due to this arrangement, only cleanroom air from the cleanroom is used by the air handling unit for cleaning and / or cooling.

[0022] In another embodiment, at least one of the following is fulfilled: - the air inlet is located in the upper half, upper third or upper quarter of the cleanroom; - the air inlet is located adjacent to an air supply outlet of a cleanroom air supply system (e.g., located in the ceiling area of ​​the cleanroom) for supplying cleanroom air into the cleanroom; and - The air inlet is located in a ceiling area of ​​the cleanroom.

[0023] The air distribution system can thus advantageously draw cleanroom air from a particularly particle-free area of ​​the cleanroom. This area can be particularly particle-free because, on the one hand, any particles present in the cleanroom sink due to gravity, and on the other hand, the cleanroom air is advantageously supplied from above or in the ceiling area of ​​the cleanroom using a top-down principle.

[0024] In one embodiment, the at least one device has at least one container holder, preferably a neck-handling container holder, for holding a container. The air outlet can be located essentially at the same level as the at least one container holder or below it. Optionally, the air outlet can be directed horizontally or downwards. This advantageously prevents particles carried by the directed cleanroom airflow from reaching, for example, the container opening and contaminating it.

[0025] For example, the container treatment plant can be designed for tempering, manufacturing, cleaning, coating, testing, filling, closing, pasteurizing, labeling, printing, marking, laser marking and / or packaging containers for liquid or pasty media, preferably beverages, liquid food products or products from the pharmaceutical or healthcare industry.

[0026] For example, the containers can be designed as bottles, cans, canisters, cartons, vials, tubes, etc.

[0027] Another aspect concerns a method for operating a container treatment plant, preferably as disclosed herein, with a cleanroom (e.g., pressurized and / or supplied with sterile air). The method comprises (e.g., controlled by a control device of the container treatment plant): - Transporting and / or treating containers using at least one device of the container treatment plant in the cleanroom; - Drawing in cleanroom air (e.g. sterile air) through an air inlet located in the cleanroom of an air supply unit (e.g. cleaning and / or cooling) by means of an air conveying unit of the air supply unit; - Conveying the drawn-in cleanroom air through a fluid line of the air handling unit to an air outlet of the air handling unit; - Discharging the conveyed cleanroom air as a directed cleanroom air stream (e.g., sterile air stream) from the air outlet, preferably in a direction towards a component of the container treatment system to be cleaned and / or cooled and / or to flow along the transported and / or treated containers; and - Cleaning and / or cooling using the directed cleanroom airflow.

[0028] The same advantages can be achieved with this method as have already been explained with reference to the tank treatment plant. The same applies to the preferred examples of the method described below.

[0029] In one embodiment, at least one of the following is fulfilled: - the directed cleanroom airflow is directed in a horizontal direction or downwards; - the directed cleanroom airflow hits the component and / or passes through the component to clean and / or cool the component; - the directed cleanroom airflow removes particles from the component, preferably in a downward direction; - the directed cleanroom airflow deflects particles trickling down from the containers (e.g. away from one or the component to be cleaned and / or cooled, preferably sensor device, of the container treatment system); - the directed cleanroom airflow is oriented in such a way that it flows only below a container opening of the transported and / or treated containers; - Suction, conveying, dispensing, cleaning and / or cooling take place during the transport and / or treatment of the containers; and - Suction, conveying, dispensing and cleaning and / or cooling are carried out continuously during the transport and / or treatment of the containers or discontinuously at predetermined times during the transport and / or treatment of the containers.

[0030] In another embodiment, the component is a sensor device, preferably for detecting the containers located in the cleanroom. Optionally, the sensor device is a non-contact and / or optical sensor device, preferably comprising at least one camera, an ultrasonic sensor, a laser sensor, a distance sensor, and an LED sensor.

[0031] In a further embodiment, the method also features: - Driving the air conveying unit, which is located in the cleanroom, from outside the cleanroom by means of a drive unit (e.g., the air guide device), wherein the drive unit is located outside the cleanroom. Preferably, an outer wall of the cleanroom can have a sealed shaft penetration through which a drive shaft runs, connecting the drive unit to the air conveying unit.

[0032] Preferably, the term "control device" as used herein may refer to electronics (e.g., implemented as a driver circuit or with microprocessor(s) and data storage) and / or mechanical, pneumatic, and / or hydraulic control systems, which, depending on their design, can perform control tasks, regulation tasks, and / or processing tasks. Although the term "control" is used herein, it may also appropriately encompass or refer to "regulation" or "control with feedback" and / or "processing."

[0033] The previously described preferred embodiments and features of the invention can be combined with one another in any way. Brief description of the character

[0034] Further details and advantages of the invention are described below with reference to the accompanying drawing. It shows: Fig. 1 A schematic representation of a container treatment plant according to an exemplary embodiment. Detailed description of exemplary embodiments

[0035] The Fig. Figure 1 shows a purely schematic representation of a container treatment plant 10, e.g. a beverage bottling plant.

[0036] The container treatment plant 10 has a cleanroom 12, at least one device 20, 22, 24, an air guidance device 30 and optionally a component 28.

[0037] Cleanroom 12 can also be referred to as an isolator. Cleanroom 12 can be essentially free of or low in particles (e.g., particles of all types and sizes). Sterile cleanroom conditions can prevail in cleanroom 12. Cleanroom 12 can also be designed or referred to as a sterile or aseptic room, since it is preferably essentially free of microorganisms.

[0038] Cleanroom 12 can be supplied with sterile air (cleanroom air). Preferably, cleanroom 12 can be supplied with sterile air such that the air pressure inside cleanroom 12 is greater than in the surrounding area or outside cleanroom 12.

[0039] The sterile air can preferably be supplied to the cleanroom 12 via a cleanroom air supply 14. Preferably, the cleanroom air supply 14 can supply the sterile air to the cleanroom 12 from above or in the ceiling area of ​​the cleanroom 12. For example, an air supply outlet of the cleanroom air supply 14, through which the sterile air flows into the cleanroom 12, can be arranged in the ceiling area of ​​the cleanroom 12.

[0040] The cleanroom air supply 14 can, for example, include a sterile air source. The sterile air source can supply sterile air to the cleanroom 12. The sterile air source can, for example, include at least one air filter and / or an air conveying device, e.g., a blower or compressor.

[0041] Preferably, the sterile air source can be located outside the cleanroom 12 or be accessible from outside the cleanroom 12, so that components (e.g., air filter and / or air conveying device) of the sterile air source can preferably be serviced, repaired or replaced from outside the cleanroom 12.

[0042] The cleanroom 12 can, for example, have an enclosure. The at least one device 20, 22, 24 and the optional component 28 can be enclosed by the enclosure, e.g., from above and from the sides. The air distribution system 30 can also be at least partially enclosed by the enclosure, e.g., from above and from the sides.

[0043] The cleanroom 12 can have an inlet airlock 16 for the containers. A transport device can move the containers through the inlet airlock from outside the cleanroom 12 into the cleanroom 12. Preferably, the containers can be sterilized or disinfected in the inlet airlock 16 or upstream of it. For example, the containers can be treated with a sterilization medium containing hydrogen peroxide in or upstream of the inlet airlock, e.g., by spraying or misting.

[0044] The cleanroom 12 may also have an outlet airlock 18 for the containers. A transport device can convey the containers through the outlet airlock 18 from inside the cleanroom 12 to outside the cleanroom 12.

[0045] The at least one device 20, 22, 24 can treat and / or transport the containers in the cleanroom 12. The at least one device 20, 22, 24 is arranged in the cleanroom 12. Preferably, the at least one device 20, 22, 24 can be arranged downstream of the inlet lock 16 and upstream of the outlet lock 18.

[0046] The at least one device 20, 22, 24 can comprise any conceivable device for handling and / or transporting containers.

[0047] For example, at least one treatment device 20, 24 can be included, by which the containers can be treated, e.g., manufactured, filled and / or sealed, and optionally transported. Preferably, the at least one treatment device 20, 24 can each have several treatment stations for the simultaneous or overlapping treatment of several containers. The treatment stations can preferably be arranged around the circumference of a rotatable carousel of the at least one treatment device 20, 24, which is preferably designed as a rotary device.

[0048] For example, at least one transport device 22 can be included, from which the containers can be transported. The transport device 22 can support the containers during transport, for example, at the bottom, around the circumference, and / or in the neck area (so-called neck handling). The at least one transport device 22 can, as in Fig. Figure 1 shows, for example, a rotary transport device 22 or a so-called transport star. However, it is also possible that the at least one transport device is or is a linear transport device (not shown in Figure 1). Fig. 1 shown).

[0049] The at least one device 20, 22, 24 can each have several container holders 26 with which the containers can be held during treatment and / or transport. The container holders 26 can, for example, each have a support plate on which a container can stand upright. Alternatively or additionally, the container holders 26 can, for example, each have a clamp or gripper that can hold a container by its body, neck, and / or neck ring. For example, the container holders 26 (e.g., together with the respective treatment stations) can be arranged distributed around the circumference of a rotatable carousel of the at least one device 20, 22, 24, which is preferably designed as a rotary unit.

[0050] Component 28 can be located in cleanroom 12. Component 28 can be cleaned and / or cooled by the air handling unit 30. Cleaning may be necessary, for example, because abrasion during handling / transport of the containers in cleanroom 12, such as during neck handling, can cause particles to be generated in cleanroom 12 and, for example, trickle down from the containers. These particles can contaminate component 28 and impair its functionality.

[0051] For example, component 28 can be a sensor device, as exemplified in Fig. Figure 1 shows the sensor device. The containers and / or components of the at least one device 20, 22, 24, such as the container holders 26, can be detected and monitored using the sensor device. The air guide 30 can be used to clean and / or cool the sensor device, preferably to maintain its functionality.

[0052] Preferably, the sensor device can be a non-contact and / or optical sensor device. For example, the sensor device can include a camera, an ultrasonic sensor, a laser sensor, a distance sensor, and / or an LED sensor.

[0053] It is also possible that component 28 is, for example, an electrical or electronic component or a bearing, e.g., a rotary bearing, which needs to be cleaned and / or cooled.

[0054] In general terms, component 28 can be any component located in cleanroom 12 that needs to be cleaned and / or cooled.

[0055] It is understood that several components 28 may also be included, which can be cleaned and / or cooled by the air handling unit 30 by means of a respective directed cleanroom airflow or a common directed cleanroom airflow.

[0056] The air guidance device 30 has an air inlet 32, a fluid line 34, an air conveying unit 36 ​​and an air outlet 44.

[0057] The air inlet 32 ​​is arranged in the cleanroom 12 to receive cleanroom air from the cleanroom 12. Preferably, the air inlet 32 ​​can be arranged inside the enclosure of the cleanroom 12.

[0058] For example, the air inlet 32 ​​can be located in an upper half, an upper third, or an upper quarter of the cleanroom 12, e.g., in a ceiling area of ​​the cleanroom 12 or the enclosure. For example, the air inlet 32 ​​can be suspended from the ceiling area.

[0059] The air inlet 32 ​​of the air guide device 30 can particularly preferably be arranged adjacent to the air supply outlet of the cleanroom air supply 14, e.g. within a radius of ≤ 2 m or ≤ 1 m to the air supply outlet.

[0060] Preferably, the air inlet 32 ​​can be configured as a free end of a duct. This free end of the duct can be located within the cleanroom 12 to receive cleanroom air directly from the cleanroom 12. The cleanroom air can then flow directly from the cleanroom 12 into the air inlet 32.

[0061] Fluid line 34 connects air inlet 32 ​​and air outlet 44. Cleanroom air can be conveyed from air inlet 32 ​​to air outlet 44 via fluid line 34. Fluid line 34 can be configured as a single pipe or as a pipe system.

[0062] Preferably, the length of the fluid line 34 on the pressure and suction side with respect to the air conveying unit can be kept as short as possible and the fluid line 34 can be designed according to hygienic requirements.

[0063] Preferably, the fluid line 34 runs completely within the cleanroom 12. The fluid line 34 can be arranged inside the enclosure of the cleanroom 12.

[0064] The air conveying unit 36 ​​is designed to convey air. For example, the air conveying unit 36 ​​can be a blower or a compressor. The air conveying unit 36 ​​can convey the air at a pressure level higher than the pressure level of the cleanroom air in cleanroom 12.

[0065] The air conveying unit 36 ​​is arranged in the fluid line 34. Cleanroom air can be drawn in from the air inlet 32 ​​by means of the air conveying unit 36. The air conveying unit 36 ​​can then convey the drawn-in cleanroom air through the fluid line 34 to the air outlet 44.

[0066] The air conveying unit 36 ​​is preferably arranged in the cleanroom 12, as shown in Fig. Figure 1 is shown as an example. Preferably, the air conveying unit 36 ​​is arranged inside the enclosure of the cleanroom 12.

[0067] Alternatively, for example, the air conveying unit 36 ​​is possible to be located outside of cleanroom 12 (not inside). Fig.(1 shown). For example, the fluid line 34 may have a section that runs outside the cleanroom 12. The air conveying unit 36 ​​may be located in this section. The section may be located downstream of the air inlet 32 ​​and upstream of the air outlet 44.

[0068] A drive unit 38 can be connected to the air conveying unit 36 ​​in a driving manner. For example, the drive unit 38 is connected to the air conveying unit 36, e.g., a conveying wheel or a conveying piston, by means of a drive shaft 40. The drive unit 38 can, for example, be an electric motor.

[0069] The air conveying unit 36 ​​can, for example, be operated continuously during operation of the at least one device 20, 22, 24 and / or be driven by the drive unit 38, e.g., controlled by a control device of the air guidance device 30. Alternatively, the air conveying unit 36 ​​can, for example, be operated discontinuously during operation of the at least one device 20, 22, 24 and / or be driven by the drive unit 38, e.g., controlled by a control device of the air guidance device 30.

[0070] Preferably, the drive unit 38 is arranged outside the cleanroom 12. The drive shaft 40 can preferably pass through a sealed shaft penetration 42 in an outer wall of the cleanroom 12 or the enclosure.

[0071] Alternatively, for example, the drive unit 38 is possible to be arranged within the cleanroom 12 and encapsulated.

[0072] The air outlet 44 is located in the cleanroom 12. Preferably, the air outlet 44 is located adjacent to the component 28.

[0073] The air outlet 44 is designed to receive the cleanroom air conveyed by the air conveying unit 36 ​​through the fluid line 34 and to discharge it as a directed cleanroom airflow R for cleaning and / or cooling. For example, the air outlet 44 can have a nozzle section for generating the directed cleanroom airflow R and / or be designed as a free line end.

[0074] Preferably, the directed cleanroom airflow R can be discharged in one direction towards component 28 to cool and / or clean it. Alternatively or additionally, the directed cleanroom airflow R can, for example, flow along the containers held by the container supports 26 and thereby deflect (redirect / carry away) particles trickling down from the containers.

[0075] The air outlet 44 is preferably directed horizontally or downwards. Accordingly, the cleanroom airflow R can be directed horizontally or downwards.

[0076] For example, the air outlet 44 can be arranged at the level of the container supports 26 or below the container supports 26. Preferably, the directed cleanroom airflow R is oriented such that it flows only below a container opening of the containers transported and / or treated by the at least one device 20, 22, 24.

[0077] Specifically, the air outlet 44 can be oriented relative to the component 28 such that the directed cleanroom airflow R emitted from the air outlet 44 strikes and / or passes over (flows past) the component 28. For example, the directed cleanroom airflow R can pass over and / or strike a sensor window or sensor surface of the component 28, which is configured as a sensor device. The directed cleanroom airflow R can remove particles from the component 28 and / or cool the component 28.

[0078] The invention is not limited to the preferred embodiments described above. Rather, a multitude of variants and modifications are possible, which also make use of the inventive concept and therefore fall within the scope of protection. In particular, the invention also claims protection for the subject matter and the features of the dependent claims independently of the referenced claims. In particular, the individual features of independent claim 1 are each disclosed independently of one another. In addition, the features of the dependent claims are also disclosed independently of all features of independent claim 1 and, for example, independently of the features relating to the presence and / or configuration of the cleanroom, which discloses at least one device, the air distribution system, the air inlet, the fluid line, the conveying unit, and / or the air outlet of independent claim 1.All range specifications herein are to be understood as disclosed in such a way as to disclose all values ​​falling within the respective range individually, e.g. also as preferred narrower outer limits of the respective range.
