Device and plant for treating containers

Abstract

The invention relates to a device (12, 14, 16), preferably a rotary device, for treating containers for a container treatment plant (10). The device (12, 14, 16) has a part (20), a pivot bearing (22) which rotatably supports the part (20), and a vibration sensor (26) which is arranged on the pivot bearing (22) in order to detect mechanical vibration of the pivot bearing (22). With this technique, critical bearing points, such as main bearings, rotary ball connectors, etc. can advantageously be monitored by means of vibration monitoring in order to predict wear or imminent failure. It has been recognized that mechanical vibration monitoring is particularly advantageous here, since it can detect wear and failure of a bearing very much earlier and very much more accurately than pure temperature monitoring or acoustic monitoring, for example.

[0001] DESCRIPTION

[0002] Device and system for treating containers

[0003] Technical field

[0004] The invention relates to a device for treating containers for a container treatment plant. The invention further relates to a container treatment plant.

[0005] Technical background

[0006] Container handling equipment can incorporate a variety of bearings, including critical bearings whose failure can lead to extended machine and plant downtime. Examples include the filler main bearing, the capper main bearing, and the labeling machine main bearing.

[0007] Traditionally, bearing wear and failures cannot be predicted. A failure occurs suddenly and unexpectedly. One way to prevent failures is to replace the bearings prophylactically at specific intervals. However, this can also incur unnecessary costs.

[0008] DE 10 2017 115 915 A relates to a device for treating a container in a product filling plant, preferably for filling a container with a product in a product filling plant. The device comprises a treatment carousel rotatable relative to a stationary part of the plant and a rotary distributor for transferring a medium from the stationary part of the plant to the treatment carousel. A monitoring device is provided for monitoring the mechanical integrity of the rotary distributor while the treatment carousel is rotating.

[0009] The invention is based on the objective of creating an improved technique for preventing or avoiding bearing failure in a container treatment device.

[0010] Summary of the invention

[0011] The problem is solved by the features of independent claim 1. Advantageous embodiments are specified in the dependent claims and the description. One aspect of the present disclosure relates to a device, preferably a rotary device, for treating containers for a container treatment plant. The device comprises a part, a rotary bearing that rotatably supports the part, and a vibration sensor. The vibration sensor is arranged on the rotary bearing to detect a mechanical vibration (e.g., a mechanical vibration pattern) of the rotary bearing (e.g., on an inner bearing ring, an outer bearing ring, a bearing cup, or a bearing plate).

[0012] This technique allows critical bearing components, such as main bearings, ball joints, etc., to be monitored using vibration monitoring to predict wear or impending failure. Mechanical vibration monitoring has proven particularly advantageous because it can detect wear and impending bearing failure much earlier and more accurately than, for example, temperature or acoustic monitoring alone. This allows for longer component lifetimes in the machine, as replacement only occurs when the bearing exhibits abnormal vibration values. Overall, this results in reduced downtime and outages, leading to increased efficiency. Finally, the accuracy of mechanical vibration monitoring enables well-planned overhauls.

[0013] In one embodiment, the vibration sensor comprises at least one acceleration sensor, preferably a radial acceleration sensor arranged to detect acceleration of the rotary bearing in a radial direction with respect to an axis of rotation of the rotary bearing, and / or a vertical acceleration sensor arranged to detect acceleration of the rotary bearing in a vertical direction. Advantageously, this allows the mechanical vibrations of the rotary bearing to be determined very accurately and with good evaluability in the spatial directions relevant for wear determination.

[0014] In a further embodiment, the device also includes an evaluation unit configured to: compare a vibration parameter, preferably frequency or amplitude, of the mechanical vibration of the rotary bearing detected by the vibration sensor with a predetermined limit value; and, depending on the comparison, output a warning signal, preferably to a control unit of the device and / or to a user interface of the device; and optionally filter out at least one predetermined frequency in the mechanical vibration of the rotary bearing detected by the vibration sensor, wherein preferably the at least one predetermined frequency is caused by the treatment of the containers by the device.

[0015] Advantageously, if vibration values ​​fall outside a predefined process window, a warning or alarm can be issued. The evaluation can be particularly precise because irrelevant (known) frequencies from mechanical vibrations of other components, etc., can be easily filtered out of the vibration pattern. Preferably, the evaluation can be performed in the machine control, in a separate controller, or in a watchdog timer.

[0016] In another embodiment, the limit value is predetermined depending on the current rotational speed of the rotary bearing, the current power output of the device, and / or the container format of the containers currently being processed by the device. Advantageously, this allows different influences on the vibration pattern to be taken into account, enabling the reliable and rapid detection of abnormal mechanical vibrations under the current operating conditions.

[0017] In a further embodiment, the device also includes a temperature sensor arranged on the rotary bearing to detect the bearing's temperature. Advantageously, this allows wear and an impending failure of the rotary bearing to be detected through temperature monitoring.

[0018] In one embodiment, the limit value is predetermined depending on the temperature detected by the temperature sensor (e.g., from several predefined temperature-dependent limit values ​​or from a predefined temperature-dependent limit value range). Advantageously, different limit values ​​can be defined for different temperatures of the rotary bearing, thereby further increasing the accuracy of the monitoring and prediction.

[0019] In a further embodiment, the device also includes an adapter block via which the vibration sensor is connected to the rotary bearing. Optionally, the adapter block can be attached to an inner bearing ring of the rotary bearing, to an outer bearing ring of the rotary bearing, to a bearing cup, to a bearing plate, or to a bearing table (e.g., detachably, preferably by means of a screw connection, or permanently, preferably by means of an adhesive bond). Alternatively or additionally, the adapter block can have a curved contact surface, preferably annular segment or cylindrical segment, which bears flat against a curved contact surface, preferably annular segment or cylindrical segment, facing the rotary bearing. This advantageously simplifies the mounting of the vibration sensor and improves the mechanical transmission of vibrations from the rotary bearing to the vibration sensor.The adapter block can also enable straightforward retrofitting to an existing device.

[0020] In one embodiment, the temperature sensor is connected to the rotary bearing via the adapter block, or the device includes a further adapter block through which the temperature sensor is connected to the rotary bearing. Optionally, a sensor head of the temperature sensor can be screwed into a threaded hole in the adapter block or the further adapter block, preferably filled with thermal paste. This advantageously simplifies the mounting of the temperature sensor and improves heat transfer from the rotary bearing to the temperature sensor.

[0021] In another embodiment, the device further comprises insulation, preferably plastic or foam insulation, wherein the insulation partially or completely surrounds the rotary bearing. Preferably, the adapter block can be inserted into a recess in the insulation, and optionally, the adapter block can be glued into the recess. Advantageously, this allows for a particularly secure connection of the vibration sensor without compromising the insulation functionality.

[0022] In one embodiment, the vibration sensor and optionally a temperature sensor are: arranged on a bearing outer ring, preferably on the upper side of the bearing outer ring of the rotary bearing, or on an annular bearing plate, preferably on the upper and / or lower side of the annular bearing plate; or on a bearing cup, preferably on an outer circumferential surface of the bearing cup; or on a bearing table, preferably on an inner circumferential surface of a central opening of the bearing table.

[0023] Advantageously, this allows for an arrangement close to the rotary bearing, ensuring good vibration and heat transfer to the respective sensor, while simultaneously facilitating easy mounting of the sensor. In another embodiment, the device is a filling device for filling the containers, a closing device for closing the containers, or a labeling device for labeling the containers.

[0024] In one embodiment, the part is a main shaft of the device, preferably vertically oriented and / or centrally located, and the rotary bearing is a main rotary bearing of the device that rotatably supports the main shaft. Alternatively, the part can be, for example, a carousel (e.g., a container handling carousel or container transport carousel) or a rotatable upper part of the device, and the rotary bearing can be a ball swivel joint of the device that rotatably supports the carousel or the rotatable upper part. Alternatively, the part can be, for example, a rotatable container transport carousel, and the rotary bearing can mount a label brushing device stationary relative to the rotatable container transport carousel.

[0025] Another aspect of the present disclosure relates to a container treatment plant comprising a first device as disclosed herein, a second device as disclosed herein, and optionally a third device as disclosed herein. Advantageously, the same advantages can be achieved with the container treatment plant as have already been described with reference to the device.

[0026] In one embodiment, the first device is a filling device, a closing device, and a labeling device, and the second device is another of the filling device, the closing device, and the labeling device. Optionally, the third device can be a remaining combination of the filling device, the closing device, and the labeling device.

[0027] In another embodiment, the tank treatment system also includes a common evaluation unit configured to receive and evaluate signals from the sensors of the devices. Advantageously, this allows the vibration signals and, if applicable, temperature signals from several devices to be evaluated by the common evaluation unit, thereby reducing, for example, the effort required for monitoring.

[0028] Preferably, the container handling system can be configured for tempering, manufacturing, cleaning, coating, testing, filling, sealing, 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 industries. For example, the containers can be bottles, cans, canisters, cartons, vials, tubes, etc.

[0029] Preferably, the term "evaluation unit" or "control unit" can refer to electronics (e.g., implemented as a driver circuit or with microprocessor(s) and data storage) that, depending on its design, can perform control tasks, regulation tasks, and / or processing tasks. Although the term "control" is used here, it can also appropriately encompass or refer to "regulation" or "control with feedback" and / or "processing."

[0046] Detailed en

[0047] Figure 1 shows a container treatment plant 10.

[0048] The container treatment plant 10 includes, for example, a filling device 12, a closing device 14, a labeling device 16 and / or at least one container conveyor 18.

[0049] The filling device 12 can fill containers, preferably with a liquid or pasty medium. The filling device 12 is preferably designed as a rotary filling device. The filling device 12 can have several filling valves for the simultaneous or overlapping filling of several containers. For example, the filling valves can be arranged around the circumference of a filling carousel of the filling device 12. The closing device 14 can close the filled containers, e.g., with a lid, a cork, a crown cap, or a screw cap. The closing device 14 is preferably designed as a rotary closing device. The closing device 14 can have several closing stations for the simultaneous or overlapping closing of several containers. For example, the closing stations can be arranged around the circumference of a closing carousel of the rotary closing device.The closing device 14 can be arranged downstream of the filling device 12 with respect to a container flow.

[0050] The labeling device 16 can label the containers, e.g., with self-adhesive labels, cold glue labels, or roll labels. The labeling device 16 is preferably designed as a rotary labeling device. The labeling device 16 can, for example, have several rotatable container holders (e.g., container turntables) for the containers, arranged around the circumference of a labeling carousel of the rotary labeling device. The container holders, with the containers held in or on them, can be moved past at least one labeling unit of the labeling device 16. The at least one labeling unit can, for example, be arranged at the periphery of the rotary labeling device. With respect to a container flow, the labeling device 16 can, for example, be arranged downstream of the filling device 12 and / or the closing device 14.

[0051] The at least one container conveyor 18 can transport the containers through the container handling system 10. The at least one container conveyor 18 can connect the container handling devices 12, 14 and / or 16 to each other. The at least one container conveyor 18 can, for example, have at least one transport star wheel and / or at least one linear conveyor.

[0052] Figure 2 shows, purely schematically, that at least one of the devices 12, 14, 16 (or another container treatment device of a container treatment plant) has a part 20 and a rotary bearing 22.

[0053] The pivot bearing 22 allows part 20 to rotate. For example, the pivot bearing 22 can allow part 20 to rotate relative to another part 24. For example, one of the two parts 20, 24 can be rotatable, and the other part 20, 24 can be stationary. However, it is also possible for both parts 20, 24 to be rotatable.

[0054] An axis of rotation of the rotary bearing 22 is preferably a main axis of rotation, e.g., a central vertical axis, of the device 12, 14, 16, which is preferably designed as a rotary device. For example, the part 20 can be a main shaft of the (rotary device) 12, 14, 16, preferably vertically oriented and / or centrally located. The main shaft can preferably be vertically oriented and / or centrally located. The main shaft can, for example, be driven by a drive unit, e.g., an electric motor. The rotary bearing 22, in turn, can be a main rotary bearing of the (rotary device) that rotatably supports the main shaft.

[0055] In another example, part 20 could be, for instance, a carousel or a rotating upper section of the (rotary) device. The carousel could, for example, be a container handling carousel. This container handling carousel could be, for instance, a filler carousel with multiple filling elements or a capping carousel with multiple capping elements. Alternatively, the carousel could be, for example, a container transport carousel, such as a rotating container table of the labeling device 16. The rotary bearing 22, in turn, could be a ball bearing of the device 12, 14, 16. The ball bearing can rotatably support the carousel or the rotating upper section.

[0056] A vibration sensor 26 is arranged on the rotary bearing 22. For example, the vibration sensor 26 can be attached to a component of the rotary bearing 22 or to a component connected to the rotary bearing 22.

[0057] The vibration sensor 26 is designed to detect mechanical vibration of the rotary bearing 22. For example, the vibration sensor can detect a mechanical vibration pattern of the rotary bearing 22 during operation of the device 12, 14, 16.

[0058] Preferably, the vibration sensor 26 can have at least one acceleration sensor. For example, the vibration sensor 26 can have a radial acceleration sensor. The radial acceleration sensor can be arranged such that it can detect an acceleration of a component of the rotary bearing 22 in a radial direction with respect to a main axis of rotation of the rotary bearing 22. Alternatively or additionally, the vibration sensor 26 can, for example, have a vertical acceleration sensor. The vertical acceleration sensor can be arranged such that it can detect an acceleration of a component of the rotary bearing 22 in a vertical direction.

[0059] Preferably, a temperature sensor 28 can be arranged on the rotary bearing 22. Preferably, the temperature sensor 28 is arranged adjacent to the vibration sensor 26. The temperature sensor 28 can be attached to a component of the rotary bearing 22 or to a component connected to the rotary bearing 22. The vibration sensor 26 can preferably be connected to the rotary bearing 22 via an adapter block 30. The adapter block 30 can be attached directly to a component of the rotary bearing 22. Alternatively, the adapter block 30 can, for example, be attached to a component that is attached to a component of the rotary bearing 22.

[0060] The adapter block 30 can be attached, for example, to an inner bearing ring of the rotary bearing 22, to an outer bearing ring of the rotary bearing 22, to a bearing cup, to a bearing plate, or to a bearing table. The attachment can be detachable, preferably by means of a screw connection. Alternatively, the attachment can be material-bonded, preferably by means of an adhesive bond.

[0061] Preferably, the adapter block 30 can have a contact surface that bears flat against a contact surface of the inner bearing ring, the outer bearing ring, the bearing cup, the bearing plate, or the bearing table. The contact surfaces can each be flat or curved, e.g., curved in a ring segment shape or a cylindrical segment shape.

[0062] It is possible that the temperature sensor 28 is also connected to the rotary bearing 22 via the adapter block 30. Alternatively, a further adapter block can be included, through which the temperature sensor 28 is connected to the rotary bearing 22 (not shown in Figure 2). Preferably, a sensor head of the temperature sensor 28 can be screwed into a threaded hole in the adapter block 30 or the further adapter block, preferably filled with thermal paste.

[0063] It is also possible that at least one of the devices 12, 14, 16 has several parts 20, several rotary bearings 22 and several vibration sensors 26, which are arranged on the several rotary bearings 22 to detect a mechanical vibration of the respective rotary bearing 22, and optionally several temperature sensors 28, which are arranged on the several rotary bearings 22 to detect a temperature of the respective rotary bearing 22.

[0064] For example, in the device 12, 14, or 16, a first part 20 can be rotatably mounted on a first rotary bearing 22, on which a first vibration sensor 26 and optionally a first temperature sensor 28 are arranged. In the same device 12, 14, or 16, a second part 20 can be rotatably mounted on a second rotary bearing 22, on which a second vibration sensor 26 and optionally a second temperature sensor 28 are arranged. In the same device 12, 14, or 16, a third part 20 can optionally be rotatably mounted on a third rotary bearing 22, on which a third vibration sensor 26 and optionally a third temperature sensor 28 are arranged. An evaluation unit 32 can be in communication with the vibration sensor 26 and optionally with the temperature sensor 28. The evaluation unit 32 can receive and evaluate measurement signals from the vibration sensor 26 and optionally the temperature sensor 28.

[0065] Preferably, the evaluation device 32 can be configured to compare a vibration parameter, preferably a frequency or an amplitude, of the mechanical vibration of the rotary bearing 22 detected by the vibration sensor 26 with a predetermined limit value.

[0066] Preferably, no fixed limit is specified. Instead, a variable limit can be specified.

[0067] Preferably, the limit value can be predefined as temperature-dependent. The limit value can be different for different current temperatures of the rotary bearing 22. For example, the limit value can be higher at a lower temperature of the rotary bearing 22 than at a higher temperature of the rotary bearing 22. Preferably, the limit value can be predefined as dependent on a temperature of the rotary bearing 22 detected by the temperature sensor 28.

[0068] Preferably, the limit value can be predefined depending on the current rotational speed of the rotary bearing 22, the current power output of the device 12, 14, 16, and / or the container format of the containers currently being processed by the device 12, 14, 16. Thus, different limit values ​​can apply for different rotational speeds, different power outputs, and / or different container formats. The evaluation unit 32 can receive current rotational speed information, current power information, and / or current container format information, for example, from the user interface 34 and / or the control unit 36 ​​and / or at least one other sensor of the device 12, 14, 16.

[0069] The temperature-, speed-, power- and / or container-format-dependent specification of the limit value can be implemented programmatically, for example, by empirically and / or simulation-generated tables, characteristic maps, formulas, algorithms and / or other assignments.

[0070] The evaluation unit 32 is particularly preferably configured to filter out predefined frequencies in the mechanical vibration of the rotary bearing 22 detected by the vibration sensor 26. These predefined frequencies can be caused, for example, by the treatment of the containers by the respective device 12, 14, 16. Preferably, the evaluation unit 32 can output a warning signal depending on the comparison, e.g., if the vibration parameter exceeds, reaches, or falls below the predefined limit value.

[0071] For example, the warning signal can be output to a user interface 34. Upon receiving the warning signal, the user interface 34 can, for example, issue an acoustic, visual, and / or haptic warning to a user.

[0072] Alternatively or additionally, the warning signal can be output to a control unit 36, e.g., of the device 12, 14, 16 or the system 10 (see Figure 1). Upon receiving the warning signal, the control unit 36 ​​can, for example, adjust the operation of the device 12, 14, 16, e.g., slow it down or stop it.

[0073] If the device 12, 14, 16 or the system 10 (see Figure 1) has several vibration sensors 26 and optionally several temperature sensors 28, it is preferred that a common evaluation unit 32 for these sensors 26, 28 is included. This common evaluation unit 32 can, for example, receive and evaluate the measurement signals from the vibration sensors 26 and the temperature sensors 28.

[0074] The following are different examples of the rotary bearing 22 with reference to Figures 3 to 14, in which the vibration and temperature monitoring explained above is particularly advantageous.

[0075] Figures 3 and 4 show a preferred application in the labeling device 16.

[0076] The labeling device 16, shown in section 3, has a rotary bearing 22A designed as a ball swivel for rotatably supporting the upper part 20A (labeling device upper part) of the labeling device 16. Preferably, the ball swivel can support a stationary lifting cam (lifting control cam) (not shown) of the labeling device 16 relative to the rotatable upper part 20A. The upper part 20A can, for example, be arranged above a lower part (container transport carousel) of the labeling device 16 that is also rotatable.

[0077] The vibration sensor 26A and optionally the temperature sensor 28A can be arranged on an outer bearing ring of the rotary bearing 22A. Preferably, the vibration sensor 26A and optionally the temperature sensor 28A are arranged on the upper surface of the outer bearing ring of the rotary bearing 22A. A sensor cable from the vibration sensor 26A and / or from the temperature sensor 28A can be routed via the upper part 20A to a column (e.g., a support column) of the labeling device 16 and then through the column, e.g., under the tabletop of the labeling device 16. The sensor cable(s) can be enclosed by at least one protective sleeve.

[0078] Preferably, the vibration sensor 26A and optionally the temperature sensor 28A are attached to the rotary bearing 22A via an adapter block 30A. Specifically, the adapter block 30A can preferably attach the vibration sensor 26A and optionally the temperature sensor 28A to a top surface of the outer bearing ring of the rotary bearing 22A.

[0079] Preferably, the adapter block 30A can be detachably attached to the outer bearing ring of the rotary bearing 22A, e.g. by means of at least one screw connection.

[0080] The adapter block 30A can have an elongated shape. Preferably, the adapter block 30A can have an arcuate curved shape. The arcuate curved shape can follow the contour of the outer bearing ring of the rotary bearing 22A. The radius of the arcuate shape of the adapter block 30A can correspond to a radius of the outer bearing ring of the rotary bearing 22A in the western direction.

[0081] The adapter block 30A can bear in contact with the outer bearing ring of the rotary bearing 22A. Preferably, a planar underside of the adapter block 30A can bear in contact with a planar upper side of the outer bearing ring of the rotary bearing 22A.

[0082] The vibration sensor 26A preferably includes a radial acceleration sensor. The radial acceleration sensor can be arranged such that it can detect an acceleration of the outer bearing ring of the rotary bearing 22A in a radial direction with respect to a main axis of rotation of the rotary bearing 22A.

[0083] The vibration sensor 26A can be in contact with the adapter block 30A over a flat surface. For example, the vibration sensor 26A can be in contact with a longitudinal outer surface of the adapter block 30A. Preferably, the adapter block 30A can have a planar contact surface against which the vibration sensor 26A rests. The vibration sensor 26A can be detachably attached to the adapter block 30A, e.g., by means of a screw connection.

[0084] The temperature sensor 28A can be screwed into a threaded hole of the adapter block 30A. The temperature sensor 28A can, for example, be screwed into the threaded hole from the top of the adapter block 30A. The threaded hole is preferably filled with thermal paste. Figures 5 and 6 show another preferred application with a filling device 12.

[0085] The filling device 12, shown section by section in Figures 5 and 6, has a rotary bearing 22B designed as a ball swivel connector for rotatably mounting a rotatable lower part / container carousel (not shown) of the filling device 12. For example, several containers can be held or supported during filling, distributed around the circumference of the container carousel. Preferably, the ball swivel connector can rotatably mount the container carousel on a bearing table 24B of the filling device 12, which is preferably annular. The bearing table 24B can be stationary.

[0086] The vibration sensor 26B can be arranged and attached to an inner circumferential side of the bearing table 24B. The inner bearing ring of the rotary bearing 22B can be attached to a top surface of the bearing table 24B, e.g., by means of a screw connection. Thus, the vibration sensor 26B can be mounted on a stationary part of the rotary bearing 22B.

[0087] The vibration sensor 26B preferably comprises a radial acceleration sensor 26B1 and / or a vertical acceleration sensor (axial acceleration sensor) 26B2. The radial acceleration sensor 26B1 can be arranged to detect an acceleration of the outer bearing ring of the rotary bearing 22B in a radial direction with respect to a main axis of rotation of the rotary bearing 22B. The vertical acceleration sensor 26B1 can be arranged to detect an acceleration of the outer bearing ring of the rotary bearing 22B in a vertical direction (axial direction of the rotary bearing 22B).

[0088] Preferably, the vibration sensor 26B (the radial acceleration sensor 26B1 and / or the vertical acceleration sensor 26B2) is attached to the rotary bearing 22B via an adapter block 30B and the bearing table 24B. Specifically, the adapter block 30B can preferably attach the vibration sensor 26B (the radial acceleration sensor 26B1 and / or the vertical acceleration sensor 26B2) to an inner circumferential side of the bearing table 24B adjacent to the (stationary) inner bearing ring of the rotary bearing 22B. The adapter block 30B can be attached, preferably by a material bond, to an inner circumferential side of a central opening of the bearing table 24B, e.g., by means of an adhesive bond.

[0089] The adapter block 30B can rest flat against the inner circumferential side of a central opening of the bearing table 24B. Preferably, a cylindrically segment-shaped contact surface of the adapter block 30B can rest flat against a cylindrically segment-shaped curved inner circumferential side of the bearing table 24B. The vibration sensor 26B (the radial acceleration sensor 26B1 and / or the vertical acceleration sensor 26B2) can rest flat against the adapter block 30B.

[0090] For example, the radial accelerometer 26B1 can be in contact with a flat surface on the top side of the adapter block 30B. For example, the vertical accelerometer 26B2 can be in contact with a flat surface on a longitudinal inner side of the adapter block 30B. Preferably, the adapter block 30B can have a planar contact surface against which the radial accelerometer 26B1 rests and a planar contact surface against which the vertical accelerometer 26B2 rests.

[0091] The vibration sensor 26B (the radial accelerometer 26B1 and / or the vertical accelerometer 26B2) can be detachably attached to the adapter block 30B, e.g. by means of at least one screw connection.

[0092] Figures 7 to 9 show another preferred application in the labeling device 16.

[0093] The labeling device 16, shown in section in Figure 7, has a rotary bearing 22C, designed as the main bearing, for rotatably supporting the main shaft 20C of the labeling device 16. Preferably, the main bearing supports the main shaft 20C in a stationary bearing cup 24C. The main shaft 20C can be vertically oriented and / or centrally located. The main shaft 20C can be driven by a drive unit. The main shaft 20C can, for example, drive the container transport carousel and / or the upper part of the labeling device 16. The main bearing can, for example, be located below the container transport carousel / container table. The main bearing can, for example, have two radial bearings and one axial bearing.
