Description

Technical Field

[0001] This invention relates to a method for setting up a cleaning operation for equipment used to fill containers with filling materials. The invention further relates to a method for cleaning equipment used to fill containers with filling materials. The invention further relates to equipment used to fill containers with filling materials. Background Technology

[0002] Various methods are known for cleaning and sterilizing filling equipment used to fill containers with filling products such as beverages. In this way, so-called CIP ("Cleaning in Place") and SIP ("Sterilization in Place") methods have been widely used, for example, in which the disassembly of parts and surfaces in contact with the filling product or intermediate products and accessories is essentially eliminated. For example, filling elements do not need to be removed for cleaning or sterilization, but are instead rinsed or steam-treated in their installed state using a cleaning medium. "CIP" or "SIP" cleaning can also be described as cleaning the interior of the processing machine, i.e., cleaning of product paths, gas paths, pipes, etc. This disclosure specifically relates to such internal cleaning. In contrast, for example, the abbreviation "COP" refers to external cleaning (all external surfaces).

[0003] For the sake of simplicity, the SIP method is referred to as the CIP method in this paper, that is, the CIP method includes cleaning and / or sterilization.

[0004] WO 2019 / 043240 A1 discloses an apparatus for filling containers with a filling product. To allow venting of the container filled with the carbonated filling product at the filling valve before removal from the valve, a release line is preferably provided, which is led outward via a rotary distributor. This release line and rotary distributor can also be used to perform CIP cleaning of the area of ​​the apparatus that carries the filling product.

[0005] DE 10 2019 132 749 A1 discloses an apparatus (preferably in a beverage bottling facility) for filling containers with a filling product and a method for cleaning and sterilizing such apparatus. The apparatus includes a main component supply section for supplying a main component (preferably water) of the filling product, at least one filling element in fluid communication with the main component supply section for filling containers to be filled with the filling product, and a CIP device for cleaning and sterilizing the parts of the apparatus that come into contact with the filling product using a CIP medium.

[0006] Traditionally, cleaning operations are manually set up on-site, a process that is both difficult and error-prone. In this respect, cleaning operations may not guarantee adequate cleaning, especially when gas paths (such as filling gas paths) must also be cleaned with a cleaning medium in addition to the filling material path. Undesirable pressure fluctuations may also occur in the system during cleaning operations, which could, for example, lead to damage to bellows.

[0007] The present invention is based on the aim of creating an improved technique for setting up cleaning operations for equipment used for filling containers, preferably using this technique to overcome at least some of the disadvantages mentioned above. Summary of the Invention

[0008] This objective is achieved through the features of the independent claims. Advantageous developments are indicated in the dependent claims and the specification.

[0009] One aspect relates to a method for (e.g., automatically) setting up a cleaning operation for equipment (preferably a rotary device) for filling containers with (e.g., liquid or paste) filling materials (e.g., beverages or food). The equipment has a plurality of filling stations, each having a filling material path, a filling material path valve arranged in the corresponding filling material path, and a flow meter arranged to measure the flow rate through the corresponding filling material path. The method includes the following steps:

[0010] - To allow cleaning media (e.g., from the cleaning media source of the device) to pass through some of the filling material paths in the filling material path by opening the corresponding filling material path valve to release at least some of the filling material paths in the filling material path;

[0011] - Use a corresponding flow meter to (e.g., repeatedly) measure the flow rate of the cleaning medium through the path of the released filling material; and

[0012] - (e.g., by the processing unit of the equipment) sets at least one valve actuation parameter of the cleaning operation of the equipment (e.g., the equipment and / or the filling station) based on the measured flow rate of the cleaning medium.

[0013] Advantageously, this method enables improved setup of the cleaning operation through the use of device technology (i.e., flow meters) for the filling operation. The flow meter can not only be used to ensure a constant filling volume in the container during the filling operation, but also advantageously to measure the flow rate of the cleaning medium. This measurement can be evaluated to find the optimal valve actuation parameters for the cleaning operation and set these parameters accordingly. In particular, it can be determined how many paths the cleaning medium can flow through simultaneously such that adequate cleaning is still achieved (e.g., for a given pipe diameter, flow at a sufficient rate through the corresponding path). The switching characteristics generated between the corresponding released paths then preferably ensure that the total cleaning medium volume flow rate remains substantially constant during the cleaning operation, which is particularly preferred because this can, for example, reduce unwanted pressure fluctuations in the system. Furthermore, error conditions can be quickly identified and reported. Using existing equipment (i.e., flow meters) advantageously makes it possible to implement this method in a cost-effective and simple manner. In addition to the cleaning process, this principle can also be applied to, for example, spraying or evacuation processes.

[0014] In one exemplary embodiment, the at least one valve actuation parameter includes a target number of filling material path valves that are simultaneously opened during the cleaning operation. This advantageously ensures that not too many filling material path valves are opened simultaneously during the cleaning operation, and therefore not too many filling material paths are simultaneously released for the passage of the cleaning medium, thus ensuring a sufficient supply of cleaning medium to each filling material path. On the other hand, it advantageously ensures that not too few filling material path valves are opened simultaneously, and therefore not too few filling material paths are simultaneously released for the passage of the cleaning medium, so that the cleaning operation does not take too long. By setting this target number, it is also relatively easy to ensure that the total cleaning medium flow rate remains constant, thus preventing or at least reducing (e.g., during switching) undesirable pressure fluctuations.

[0015] In another exemplary embodiment, the setting of the at least one valve actuation parameter further depends on a predefined cleaning media supply from a cleaning media source of the device, wherein, preferably, the predefined cleaning media supply is a nominal supply (available supply) of the cleaning media from the cleaning media source. Advantageously, the at least one valve actuation parameter (such as a specified target quantity) can be adapted to the nominal supply such that the total cleaning media flow rate can be kept constant according to the nominal supply, thereby enabling particularly efficient cleaning operations.

[0016] In one implementation, at least one of the following conditions is met:

[0017] - The target number of filling material path valves opened simultaneously during the cleaning operation is set to the number of opening filling material path valves that meet the following condition: when the number of filling material path valves is opened, the sum of the measured cleaning medium flow rates substantially corresponds to the predefined cleaning medium supply.

[0018] - The target number of filling material path valves simultaneously opened during the cleaning operation is set such that: if the sum of the measured cleaning media flow rates is less than the predefined cleaning media supply, the number of released filling material paths is increased by (e.g., continuously) opening at least one additional filling material path valve until a number of open filling material path valves is reached that: when that number of filling material path valves is opened, the sum of the measured cleaning media flow rates determined for the increased number of released filling material paths substantially corresponds to the predefined cleaning media supply; and

[0019] - The target number of filling material path valves simultaneously opened during the cleaning operation is set such that: if the sum of the measured cleaning media flow rates is greater than the predefined cleaning media supply, the number of released filling material paths is reduced by (e.g., continuously) closing at least one of the open filling material path valves until a number of open filling material path valves is reached that satisfies the condition that when that number of filling material path valves are opened, the sum of the measured cleaning media flow rates determined for the reduced number of released filling material paths substantially corresponds to the predefined cleaning media supply.

[0020] In this way, the optimal target number of filling material path valves to be opened simultaneously for the cleaning operation can be determined iteratively.

[0021] In another embodiment, the method further includes: if the sum of the measured cleaning media flow rates is outside a predefined tolerance range (e.g., greater than or less than the predefined tolerance range), outputting a fault message (e.g., visual and / or audible) using the device's user interface, the predefined tolerance range preferably beginning at the predefined cleaning media supply. This also allows for advantageous detection of errors in cleaning agent supply and dispensing, enabling subsequent, for example, manual inspection and correction of these errors.

[0022] In one embodiment variation, the plurality of filling stations further each have a gas path (gas supply path) and a gas path valve arranged in the corresponding gas path, the gas path preferably being a filling gas path and the gas path valve preferably being a filling gas path valve. Preferably, the at least one valve actuation parameter includes a target number of gas path valves simultaneously opened during the cleaning operation. Particularly preferably, the target number of gas path valves simultaneously opened is set to a number of gas path valves that achieve a predefined minimum flow rate and / or a predefined minimum flow velocity through the released gas path, and / or the target number of gas path valves simultaneously opened during the cleaning operation and the target number of filling material path valves simultaneously opened during the cleaning operation are adjusted in a coordinated manner.

[0023] This advantageously ensures that during the cleaning operation, not too many gas path valves are opened simultaneously, and where applicable, not too many filling material path valves are opened simultaneously, and therefore not too many gas or filling material paths are released simultaneously for the passage of the cleaning medium, thus ensuring a sufficient supply of cleaning medium to each path. On the other hand, it advantageously ensures that not too few paths are opened simultaneously, and therefore not too few paths are released simultaneously for the passage of the cleaning medium, so that the cleaning operation does not take too long. By setting this target number, it is also relatively easy to ensure that the total cleaning medium flow rate remains constant, thus preventing or at least reducing (e.g., during switching) unwanted pressure fluctuations. This is particularly advantageous as it eliminates the need for separate flow measurements and corresponding measuring equipment in the gas paths. Alternatively, for example, the cleaning medium flow rate through the gas path can be inferred based on the cleaning medium flow rate through the released filling material path, for example, if the total flow rate is additionally known or measured, as described in more detail in the preferred examples below.

[0024] In one exemplary implementation, the method further includes the following operations:

[0025] - The cleaning medium is passed through at least some of the gas paths, preferably all of the gas paths, by opening the corresponding gas path valve to release at least some of the gas paths, preferably in a manner that is simultaneous with or overlaps with the passage of the cleaning medium through at least some of the filling material paths.

[0026] In one exemplary implementation, the method further includes the following operations:

[0027] - Measure the clean media supply from the clean media source of the equipment and / or the clean media discharge from the plurality of filling stations (e.g., measured in the clean media return line in the equipment), wherein, preferably: the setting of the at least one valve actuation parameter further depends on the measured clean media supply and / or the measured clean media discharge.

[0028] In one implementation, the method further includes:

[0029] - The cleaning medium flow rate through the released gas path is determined based on the measured cleaning medium flow rate through the released filling material path and the measured cleaning medium supply and / or the measured cleaning medium discharge, wherein, preferably, the setting of the at least one valve actuation parameter further depends on the determined cleaning medium flow rate through the released gas path.

[0030] In another embodiment, at least one of the following conditions must be met:

[0031] - The filling material path valve is a closed-loop control valve or an open-loop control valve and / or is configured to adjust the flow cross-section between an open position and a closed position (e.g., continuously or gradually); and

[0032] - The filling material path valve (e.g., by the processing device of the equipment) operates in such a way that each filling material path valve closes with a pressure shock damping closing characteristic and / or does not close abruptly.

[0033] This advantageously enables a smooth switching between the paths for releasing the cleaning medium (fill material path and, optionally, gas path), thereby reducing additional unwanted pressure fluctuations.

[0034] In one embodiment variation, the passing cleaning medium (e.g., via the released filling material path and / or the released gas path) is dispensed from the filling station into the environment of the filling station. Alternatively, the passing cleaning medium (e.g., via the released filling material path and / or the released gas path) may be guided from the cleaning cap (e.g., CIP or SIP) of the corresponding filling station, preferably via the release path of the corresponding filling station, to the cleaning medium return line, the cleaning cap being positioned at the filling material outlet of the corresponding filling station. Therefore, the techniques described herein can be advantageously used, for example, in rinsing processes, CIP cleaning processes, and SIP cleaning processes.

[0035] In another embodiment variation, each of the filling stations has a filling valve arranged downstream of a corresponding filling material path valve in the corresponding filling material path for dispensing the filling material into a container. During the passage of a cleaning medium (e.g., through the released filling material path and / or through the released gas path), the filling valve of the corresponding filling station or all filling stations' filling valves are open.

[0036] Another aspect of the invention relates to a method for cleaning equipment used for filling containers with (e.g., liquid or paste) filling materials (e.g., beverages or food), the equipment preferably being a rotary device, wherein the equipment has a plurality of filling stations, each of the plurality of filling stations having a filling material path, a filling material path valve arranged in the corresponding filling material path, and a flow meter arranged for measuring the flow rate through the corresponding filling material path. The method includes the following steps:

[0037] - The cleaning operation of the device is set up by methods as disclosed herein (e.g., automatically); and

[0038] - (For example, automatically) perform the cleaning operation to clean the device.

[0039] Preferably, at least one of the following conditions is met:

[0040] -Preparing for the cleaning operation is preferably done during the initial commissioning of the equipment;

[0041] -Settings are executed at the start of the cleaning operation, preferably for the initial settings of the cleaning operation being performed; and

[0042] -Settings are performed during the cleaning operation, preferably several times, and preferably used to dynamically adjust the cleaning operation being performed.

[0043] In one embodiment, the cleaning operation is performed in such a way that the filling material path valve and / or gas path valve of the equipment are preferably opened and closed in a rolling manner according to the at least one set of valve actuation parameters, preferably to maintain a constant total flow rate of cleaning medium through the plurality of filling stations. Alternatively or additionally, the filling material path valve (e.g., by the processing device of the equipment) is operated in such a way that each filling material path valve closes with a pressure shock damping closing characteristic and / or does not close abruptly.

[0044] On the other hand, it relates to an apparatus for filling containers with a filling material (e.g., a liquid or paste) that is preferably a rotary device, wherein the apparatus is configured to perform the methods disclosed herein.

[0045] For example, the device may have several filling stations, each having a filling material path, a filling material path valve arranged in the corresponding filling material path, and a flow meter arranged to measure the flow rate through the corresponding filling material path. Optionally, each of the filling stations may further have a gas path (gas supply path) and a gas path valve arranged in the corresponding gas path, the gas path preferably being a filling gas path and the gas path valve preferably being a filling gas path valve. The device may further include a processing unit, which, for example, is configured together with the filling station to perform the methods disclosed herein.

[0046] On the other hand, it relates to a container handling facility (e.g., for temperature control, production, cleaning, coating, testing, filling, sealing, pasteurizing, labeling, printing, marking, laser marking, and / or packaging of containers for liquid or paste-like media (preferably beverages, liquid foods, or products in the pharmaceutical or healthcare industries). This container handling facility may include equipment as disclosed herein.

[0047] For example, the container can be constructed as a bottle, can, tube, cardboard box, vial, pipe, etc.

[0048] Preferably, the term "processing device" can refer to an electronic system (e.g., configured as a drive circuit or having a microprocessor and data memory) that, depending on its configuration, can perform open-loop control tasks and / or closed-loop control tasks and / or processing tasks. Although the term "control" is used herein, it can also include or be understood as "closed-loop control" or "control with feedback" and / or appropriate "processing".

[0049] It should be understood that the term "cleaning medium" includes any medium suitable for cleaning, particularly preferably CIP and / or SIP cleaning media. For example, rinsing water or alkaline solution can be used as a cleaning medium.

[0050] The preferred embodiments and features described above can be combined with each other as desired. Attached Figure Description

[0051] Further details and advantages of the invention are described below with reference to the accompanying drawings, in which:

[0052] Figure 1 A schematic diagram of a section of an apparatus for filling containers according to an exemplary embodiment is shown; and

[0053] Figure 2 A schematic diagram of a filling station for an exemplary device is shown.

[0054] The embodiments shown in the accompanying drawings correspond at least partially to each other, such that similar or identical parts have the same reference numerals, and in order to avoid repetition, reference is also made to the description of other embodiments or drawings for illustration. Detailed Implementation

[0055] Figure 1 A section of apparatus 10 for filling container 12 with filling material is shown. Apparatus 10 may preferably be included in a container handling facility. Apparatus 10 is preferably a beverage filling apparatus. Preferably, the filling material may be a beverage.

[0056] Equipment 10 has several filling stations 36, which, for clarity, are shown below. Figure 1 Only one of the several filling stations is shown in the diagram. The equipment 10 may further include, for example, a filling material source 14, a carbon dioxide source 20, a buffer tank 26, a sterile air or nitrogen source 34, and / or a cleaning media source 62.

[0057] exist Figure 1 The filling material source 14, shown only schematically, can provide filling material for filling container 12. The provided filling material can be, for example, (product) water or (product) water-syrup mixture. The water can be pre-cleaned, degassed, and / or treated, for example. At least one syrup can be added to the water.

[0058] Filling materials can be supplied from filling material source 14 to buffer tank 26 via main filling material line 16.

[0059] Preferably, a carbonator 18 may be arranged in the main filling material line 16. The contents may be carbonized at the carbonator 18. The carbonator 18 may, for example, be configured as at least one carbonation nozzle. Carbon dioxide for carbonation may be provided by a carbon dioxide source 20. Carbon dioxide may be supplied from the carbon dioxide source 20 to the carbonator 18 via a gas line 22.

[0060] Preferably, a bypass 24 may be arranged around the carbonator 18. Through the bypass 24, substantially the same conditions regarding the flow rate and / or pressure for carbonation (CO2 addition) can always be provided.

[0061] The filling material can be temporarily stored (buffered) in buffer tank 26. Buffer tank 26 can receive filling material via main filling material line 16. Buffer tank 26 can receive additional components for the filling material, such as syrup, via optional auxiliary filling material line 28.

[0062] Preferably, the carbonation of the filling material can be maintained in the buffer tank 26. Preferably, the buffer tank 26 can be pre-filled with carbon dioxide from the carbon dioxide source 20. The buffer tank 26 can be pre-filled with carbon dioxide, for example, at a pressure that prevents the release of carbon dioxide bound in the filling material. For example, the pre-filling of the buffer tank 26 can be achieved by a pre-filling device through which carbon dioxide from the carbon dioxide source 20 can be introduced into the top space of the buffer tank 26.

[0063] A circulation line 30 may be included to monitor the quality of the filling material in the buffer tank 26. A circulation pump 32 may be arranged in the circulation line 30. Using the circulation pump 32, the filling material can be removed from the buffer tank 26 and returned to it. At least one sensor (e.g., a carbon dioxide sensor and / or a brussels weight gain sensor) may be arranged in the circulation line 30.

[0064] The buffer tank 26 and / or the gas line 22 for receiving sterile air can be connected to the sterile air source 34.

[0065] Each filling station 36 can be connected to a buffer tank 26. Specifically, the buffer tank 26 can be connected to the filling station 36 via a filling material line 38. Filling material can be supplied from the buffer tank 26 to the filling station 36 via the filling material line 38.

[0066] Optionally, the gas space / top space of the buffer tank 26 may also be connected to several filling stations 36 via a filling gas line 40. Filling gas (carbon dioxide) can be supplied from the gas space of the buffer tank 26 to the filling stations 36 via the filling gas line 40.

[0067] Preferably, the filling station 36 may be included in the filling turntable or rotary filler 42 (only in cases where...). Figure 1 (Illustrated in the image). The filling station 36 can fill several containers 12 simultaneously or at overlapping times using filling material. For example, the filling station 36 can be arranged in a circumferential distribution around the filling turntable 42.

[0068] Preferably, the filling station 36 can receive filling material from the buffer tank 26 (and the filling material line 38) via a rotary distributor 44. Alternatively, the filling station 36 can also receive filling gas from the buffer tank 26 (and the filling gas line 40) via a rotary distributor 44.

[0069] The rotary distributor 44 can transfer filling material and (optionally) filling gas from the fixed facility portion of the device 10 to the filling turntable 42 that rotates relative to it, in which buffer tank 26 and filling material line 36 and (optionally) filling gas line 40 are arranged, etc.

[0070] Figure 2An exemplary filling station 36 is shown in more detail below.

[0071] Each filling station 36 has a filling material path 46, a filling material path valve 48, and a flow meter 50. Each filling station 36 may further include, for example, a filling valve 52, a gas path (gas supply path) 54, a gas path valve 56, a release path 58, and / or a release valve 60. Preferably, the filling valve 52, the gas path valve 56, and the release valve 60 together form the filling element of the corresponding filling station 36.

[0072] The filling material path 46 of the filling station 36 can be connected to the buffer tank 26 (see...). Figure 1 The filling material path 46 is used to receive filling material from the buffer tank 26. Preferably, the filling material path 46 may be connected to the filling material line 38, for example, via a rotary dispenser 44. For example, the filling material path 46 may be connected to the rotary dispenser 44 via an annular channel.

[0073] A filling material path valve 48 is arranged in each filling material path 46. The filling material path valve 48 may optionally allow or block flow through the corresponding filling material path 46, or optionally adjust the flow. For example, the processing device 74 of the apparatus 10 may selectively operate the filling material path valve 48 to adopt a released position or a closed position, or optionally adjust the released flow cross-section.

[0074] Preferably, the filling material path valve 48 can be a closed-loop control valve or an open-loop control valve. Preferably, the filling material path valve 48 can adjust the flow cross-section between an open position and a closed position.

[0075] A flow meter 50 is arranged in each filling material path 46. For example, as Figure 1 and Figure 2 As shown, the flow meter 50 can be arranged downstream of the filling material path valve 48 in the corresponding filling material path 46. Alternatively, the flow meter 50 can be arranged, for example, upstream of the filling material path valve 48 in the corresponding filling material path 46.

[0076] Flow meter 50 is configured to measure the flow rate through the corresponding filling material path 46. For example, flow meter 50 can detect the flow rate of filling material heading to filling valve 52. For example, flow meter 50 can measure the flow rate based on quantity and / or volume. Flow meter 50 can output a measurement signal indicating the detected flow rate to, for example, the processing device 74 of device 10.

[0077] The flow meter 50 may have any suitable flow measurement principle for detecting the flow rate. Particularly preferred is that the flow meter 50 may be a magnetic induction flow meter or an ultrasonic flow meter.

[0078] The filling valve 52 may be arranged downstream of the filling material path valve 48 and the flow meter 50. Preferably, the filling valve 52 is arranged at the downstream end region of the corresponding filling material path 46. Through the filling valve 52, filling material can be dispensed into the container 12 located below the filling valve 52.

[0079] For example, filling valve 52 can be opened to fill container 12. Filling valve 52 can be closed to prevent the flow of filling material through filling valve 52. Optionally, the flow cross-section of filling valve 52 can be adjustable, for example, to adjust the flow rate of filling material through filling valve 52.

[0080] The filling valve 52 is particularly preferably a proportional valve. Because it is constructed as a proportional valve, the flow rate of the filling product can be continuously adjusted in several stages, or particularly preferably, in particular stages.

[0081] The filling valve 52 may, for example, be configured as a cone valve. The filling valve 52 may, for example, have a valve seat into which the valve cone of the filling valve 52 descends to close the filling valve 52. The cross-section of the annular gap between the valve cone and the valve seat can be changed by gradually or continuously lifting the valve cone from the valve seat.

[0082] The gas path 54 of filling station 36 may, for example, be connected to the gas space / top space of buffer tank 26 (see...). Figure 1 The gas path 54 is used to receive filling gas from the buffer tank 26. Preferably, the gas path 54 may be connected to the filling gas line 40, for example, via a rotary distributor 44. For example, the gas path 54 may be connected to the rotary distributor 44 via an annular channel.

[0083] A gas path valve 56 may be arranged in each gas path 54. The gas path valve 56 may selectively allow or block the flow through the corresponding gas path 54. For example, the processing device 74 of the apparatus 10 may selectively operate the gas path valve 56 to adopt a released position or a closed position.

[0084] Preferably, gas path 54 can be configured as a filling gas path, and gas path valve 56 can be configured as a filling gas path valve. Preferably, filling gas (e.g., from buffer tank 26) can be supplied to the corresponding container 12 via gas path 54 and (open) gas path valve 56 for pre-filling of the container. Return gas can preferably be returned during filling via gas path 54 and (open) gas path valve 56, for example, back to buffer tank 26.

[0085] However, gas path 54 can also be connected to conduct another gas or a gas with another function, for example, to a corresponding gas source or gas tank.

[0086] Release path 58 allows for venting of the container 12 being filled with the filling product. For example, release path 58 can be connected to a rotary dispenser 44 for venting gas from the top space of the filled container 12.

[0087] A release valve 60 may be arranged in each release path 58. The release valve 60 can selectively release or prevent flow through the corresponding release path 58. For example, the processing device 74 of the apparatus 10 can selectively operate the release valve 60 to adopt a release position or a closed position.

[0088] During the filling operation of the equipment 10, the filling station 36 fills the container 12 with filling material. The filling station 36 can receive filling material from the buffer tank 26. By opening the corresponding filling material path valve 48, the corresponding filling material path 46 can be released for filling, and the filling valve 52 can be opened to fill the container 12. The desired amount of filling material for the container 12 can be set by the corresponding flow meter 50. Optionally, the container 12 can be pre-filled with filling gas via the gas path 54 before filling. By opening the corresponding gas path valve 56, the corresponding gas path 54 can be released for pre-filling.

[0089] In addition to filling operations, the device 10 can also be operated in cleaning operations. For this purpose, the device 10 may, for example, have a cleaning media source 62 (only in...). Figure 1 (Illustrated schematically). Optionally, the device 10 may further include, for example, a cleaning top cover 64 for each filling station 36 (only when...). Figure 2 (Illustrated schematically) and cleaning medium return line 66.

[0090] Cleaning media source 62 can supply cleaning media to filling station 36. The cleaning media can be used for cleaning, sterilization and / or rinsing.

[0091] For example, cleaning medium source 62 can supply cleaning medium to main filling material line 16. Cleaning medium can be supplied to buffer tank 26 via main filling material line 16. Cleaning medium can be supplied to filling material path 46 of filling station 36 via filling material line 38. Cleaning medium can also be supplied from main filling material line 16 to another filling material line 28 via connecting line 68 to be introduced into buffer tank 26, from which cleaning medium can then be supplied to filling station 36.

[0092] Preferably, the cleaning medium source 62 may also supply cleaning medium to the gas path 54 of the filling station 36 (if such a gas path exists and is desired). For example, cleaning medium may be supplied from the cleaning medium source 62 via the main filling material line 16 and via the connecting line 68 to another filling material line 28 to be introduced into the filling gas line 40. The cleaning medium may be supplied to the gas path 54 via the filling gas line 40.

[0093] For cleaning operations, the cleaning cap 64 can be moved (e.g., pivotable and / or displaceable) below the filling element or filling valve 52 of the corresponding filling station 36 to allow cleaning media exiting the filling valve 52 to return, for example, to the release path 58. Therefore, the cleaning cap 64 allows for so-called CIP (Clean-in-Place) and / or SIP (Sterilization-in-Place) cleaning of the corresponding filling element / filling station 36. The cleaning cap 64 can be configured as, for example, a (CIP) cleaning-in-place or (SIP) sterilization-in-place cleaning cap.

[0094] The returned cleaning medium can be returned to the cleaning medium return line 66 via the release path 58, which is released by opening the corresponding release valve 60. For example, the release path 58 can be supplied to the cleaning medium return line 66 via a rotary distributor 44.

[0095] Preferably, a pump 70 may be arranged in the cleaning medium return line 66. The pump 70 delivers the cleaning medium through the filling station 36 by drawing the cleaning medium into the cleaning medium return line 66. Depending on the number of released paths 46 (through the open filling material path valve 48) and / or 54 (through the open gas path valve 56), the pump 70 may draw in different volumes of cleaning agent each time, and thus cause different cleaning agent flow rates through the activated paths 46 and / or 54.

[0096] While the exemplary embodiment with a cleaning top cover 64 and a cleaning medium return line 66 (which has a pump 70) is particularly preferred, it should be noted that the technology disclosed herein is not limited thereto. Alternatively or additionally, during a flushing operation as part of a cleaning operation, for example, the corresponding filling material outlet of filling station 36 may remain idle, and the cleaning medium may escape from filling station 36 into the environment, for example, into a collection tray arranged below filling valve 52.

[0097] The device 10 may further include a user interface 72 and / or a processing device 74 for operating the device 10.

[0098] User interface 72 may be configured to receive user input and / or output information to the user. For example, user interface 72 may be a visual, auditory, and / or tactile / haptic user interface. Preferably, user interface 72 may include a preferred touch-sensitive display, speaker, microphone, keyboard, buttons, and / or at least one indicator light.

[0099] The user interface 72 can be used by the user, for example, to initiate the setting of the cleaning operation, to initiate the cleaning operation of the device 10 and / or to initiate the filling operation of the device 10.

[0100] The processing device 74 is configured to operate the device 10, for example, during a filling operation, during a cleaning operation, and / or to set up a cleaning operation.

[0101] A distinctive feature of this disclosure is the method for adjusting cleaning operations. This setting method is based on the knowledge that at least one valve actuation parameter for the cleaning operation is set based on measurements from flow meter 50 when the cleaning medium is passed through filling station 36.

[0102] At least one valve actuation parameter may preferably be at least one valve actuation parameter of the filling station 36. Particularly preferably, the at least one valve actuation parameter may have a target number of simultaneously open filling material path valves 48 and / or a target number of simultaneously open gas path valves 56, as described by way of example below. The at least one valve actuation parameter may alternatively or additionally include corresponding valve control curves for the filling material path valves 48 and / or gas path valves 56. The at least one valve actuation parameter may alternatively or additionally include corresponding opening durations for the filling material path valves 48 and / or gas path valves 56. The at least one valve actuation parameter may alternatively or additionally include corresponding opening times and / or corresponding closing times for the filling material path valves 48 and / or gas path valves 56.

[0103] The methods used to set up cleaning operations can vary depending on the level of expansion and / or degree of automation.

[0104] For example, settings can be performed, preferably during the initial commissioning of the device 10, before the actual cleaning operation of the device 10 is performed. For example, settings can be performed at the start of the cleaning operation of the device 10, preferably for the initial settings of the cleaning operation being performed. For example, settings can be performed while the cleaning operation of the device 10 is being performed, preferably several times, preferably for dynamically adjusting the cleaning operation being performed.

[0105] For example, this setting can be used only for the filling material path 46 of the cleaning filling station 36. Alternatively, this setting can be used for both the filling material path 46 and the gas path 54 of the cleaning filling station 36.

[0106] During the setup process, the cleaning medium is first passed through at least some of the filling material paths 46. For this purpose, filling material path valves 48 are opened in some of the filling material paths 46. Preferably, only the filling material paths 46 are released, without releasing any existing gas paths 54. Gas path valves 54 can be closed accordingly.

[0107] The cleaning medium can be dispensed into the environment, for example, from the filling station 36, or it can be guided to the cleaning medium return line 66 via the corresponding cleaning cap 64.

[0108] During the passage of the cleaning medium, the filling valve 52 of the corresponding filling station 36 with the released filling material path 46 can be opened, or for example, the filling valve 52 of all filling stations 36 can be opened.

[0109] For example, cleaning media via the released filling material path 46 can (e.g., in CIP or SIP cleaning) preferably be delivered from the cleaning cap 64 of the corresponding filling station 36 via the release path 58 to the cleaning media return line 66, which is positioned at the filling material outlet of the filling station 36. Alternatively, cleaning media via the released filling material path 46 can (e.g., in the case of rinsing) be dispensed from the filling station 36 into the environment of the filling station 36 via separately opened filling valves 52.

[0110] The flow rate of the cleaning medium is measured by flow meter 50 during the passage of the released filling material through path 46.

[0111] Based on the measured flow rate of the cleaning medium, a target number of filling material path valves 48 to be opened simultaneously for the cleaning operation is then preferably set automatically, preferably by means of the processing device 74. As already mentioned, the target number of filling material path valves 48 to be opened simultaneously during the cleaning operation is a preferred example of the valve actuation parameters set for the cleaning operation.

[0112] Preferably, the target number of filling material path valves 48 opened simultaneously can be set to the number of filling material path valves 48 opened that satisfies the following condition: when this number of filling material path valves are opened, the sum of the measured cleaning medium flow rates V2_sum substantially corresponds to the cleaning medium supply V1_nom, i.e., V1_nom = V2_sum.

[0113] The cleaning media supply V1_nom is a predefined value, preferably a nominal supply (available supply) of cleaning media from the cleaning media source 62. The predefined value can be received, for example, via the communication interface of device 10 or entered via user interface 72.

[0114] If the sum of the measured cleaning medium flows V2_sum is less than the predefined cleaning medium supply V1_nom, i.e., V2_sum < V1_nom, then the number of released filling material paths 46 can be increased by opening at least one additional filling material path valve in the filling material path valves 48 until the number of opened filling material path valves 48 is reached that satisfies the following condition: when this number of filling material path valves is opened, the sum of the measured cleaning medium flows V2_sum determined for the increased number of released filling material paths 46 essentially corresponds to the predefined cleaning medium supply V1_nom, i.e., V1_nom = V2_sum.

[0115] If the sum of the measured cleaning medium flows V2_sum is greater than the cleaning medium supply V1_nom, i.e., V2_sum > V1_nom, then the number of released filling material paths 46 can be reduced by closing at least one of the opened filling material path valves 48 until the number of opened filling material path valves 48 is reached that satisfies the following condition: when this number of filling material path valves is opened, the sum of the measured cleaning medium flows V2_sum determined for the reduced number of released filling material paths 46 essentially corresponds to the cleaning medium supply V1_nom, i.e., V1_nom = V2_sum.

[0116] It is also possible that an error message is issued. For example, if the sum of the measured cleaning medium flows V2_sum is outside the predefined tolerance range, the processing device 74 can operate the user interface 72 to output a fault message. The tolerance range can be predefined, for example, based on the predefined cleaning medium supply V1_nom, for example, via the user interface 72.

[0117] For example, the cleaning medium source can be capable of providing a nominal supply of 60 m [[ID=1,0]] 2 [[ID=1,1]] / h of cleaning medium. For example, if V1_nom >> V2_sum or V1_nom << V2_sum, a fault message can be issued. [[ID=1,2]] [[ID=1,3]]

[0118] [[ID=1,4]]For example, it can be determined in the above manner that in the case of 150 released filling material paths 46 (or 150 opened filling material path valves 48), the sum of the 150 measured cleaning medium flows V2_sum is approximately 400 l / h, each corresponding to, for example, approximately 60 m [[ID=1,5]] 3A predefined cleaning agent supply of / h (60000 l / h) is provided. Therefore, the target number of filling material path valves 48 simultaneously opened for the cleaning operation can be predefined as 150. During this cleaning operation, for example, only 150 of a total of 160 filling material paths 46 will be released, or for example, only 150 of a total of 160 filling material path valves 48 will be opened. The filling material path valves 48 can preferably be opened and closed in a rolling manner, such that the actual number of filling material path valves 48 simultaneously opened corresponds to the predefined target number of simultaneously opened filling material path valves 48.

[0119] If, for example, gas paths 54 exist and it is desired to take them into consideration, the setting method can be optionally modified or supplemented by taking gas paths 54 into account. When taking gas paths 54 into account, at least one valve actuation parameter to be set for the cleaning operation may preferably have a target number of gas path valves 56 that are simultaneously open during the cleaning operation.

[0120] For this purpose, the cleaning medium can be passed through at least some of the gas paths 54, preferably all of them. The gas path 54 to be released can be released by opening the gas path valve 56 arranged in the gas path 54 to be released. Preferably, this passage is performed simultaneously with or at least overlaps in time with the passage of the cleaning medium through some of the filling material paths 46.

[0121] The cleaning medium can be dispensed into the environment, for example, from the filling station 36, or it can be guided to the cleaning medium return line 66 via the corresponding cleaning cap 64.

[0122] During the passage of the cleaning medium, the filling valve 52 of the corresponding filling station 36 with the released gas path 54 and the released filling material path 46 can be opened, or for example, the filling valve 52 of all filling stations 36 can be opened.

[0123] Similarly, the flow rate of the cleaning medium through the released filling material path 46 can be measured using the corresponding flow meter 50. The sum of the measured cleaning medium flow rates is again V2_sum.

[0124] The flow rate of the cleaning medium through the released gas path 54 can then be determined, for example, by the processing device 74 as follows.

[0125] The supply of clean media from clean media source 62 and / or the discharge of clean media from filling station 36 can be measured, for example, by a flow meter (not shown in the figure) downstream of clean media source 62 and / or a flow meter (not shown in the figure) in clean media return line 66 (=V1_meas).

[0126] The cleaning medium flow rate V3_det through the released gas path 54 can be determined based on the sum of the measured cleaning medium flow rates V2_sum through the released filling material path 46 and the measured cleaning medium supply or discharge V1_meas. Preferably, the cleaning medium flow rate V3_det through the released gas path 54 can be directly calculated as the difference between the measured cleaning medium supply or discharge V1_meas and the sum of the measured cleaning medium flow rates V2_sum, i.e., V3_det = V1_meas - V2_sum.

[0127] Then, the target number of gas path valves 56 that are opened simultaneously during the cleaning operation can preferably be set according to the determined flow rate V3_det of the cleaning medium through the released gas path 54.

[0128] Preferably, the number of released gas paths 54 and / or the number of released filling material paths 46 can be varied until a cleaning medium flow rate V3_det is determined that ensures a predefined minimum flow rate and / or predefined minimum flow velocity is achieved through the released gas paths 54. For example, the corresponding pipe diameter of the gas path 54 must flow through at a minimum flow velocity of 1.5 m / s. The number of released gas paths 54 based on this determined cleaning medium flow rate V3_det can then be set as a target number of gas path valves 56 to be opened simultaneously during the cleaning operation. The number of released filling material paths 46 based on this determined cleaning medium flow rate V3_det can then be set as a target number of filling material path valves 48 to be opened simultaneously during the cleaning operation.

[0129] For example, measuring 60m 2 The equipment provides a cleaning medium supply of V1_meas at a rate of / h (60,000 l / h). It has, for example, 160 filling stations, i.e., 160 filling material path valves 48 and 160 gas path valves 56. For example, the desired cleaning medium flow rate V3_det can be obtained if the target number of simultaneously open filling material path valves 48 is approximately 75 (400 l / h at each filling material path 46) and the target number of simultaneously open gas path valves 56 is approximately 150 (200 l / h at each gas path 54). It should be understood that other combinations of target numbers are also possible, particularly combinations where the target number of simultaneously open gas path valves 56 corresponds to the total number of gas path valves 56 (i.e., 160 in this example).

[0130] Generally speaking, the target number of gas path valves 56 that are opened simultaneously during the cleaning operation and the target number of filling material path valves 48 that are opened simultaneously during the cleaning operation are adjusted in a coordinated manner.

[0131] The cleaning operation can then be performed in such a way that, according to at least one valve actuation parameter set, the filling material path valve 48 and / or the gas path valve 56 are opened and closed in a rolling manner, preferably to maintain a constant total cleaning medium flow through several filling stations.

[0132] Preferably, the filling material path valve 48 is operated during the cleaning operation to gradually change the flow rate of the cleaning medium passing through when the corresponding filling material path valve 48 is opened and closed, thereby preventing pressure fluctuations when the corresponding filling material path valve 48 is opened and closed. This can be achieved, for example, through a pressure shock damping shut-off characteristic, which, for example, eliminates the possibility of sudden closure of the corresponding filling material path valve 48.

Instead, various variations and modifications utilizing the same inventive concept are possible and therefore fall within the scope of protection. In particular, the invention also claims protection for the subject matter and features of the dependent claims, regardless of the claims they refer to.
