Description

State of the art

The present invention relates to a device and a method for handling, in particular for filling and/or closing, containers.

Processing machines are known, such as filling or sealing machines for the continuous filling and/or sealing of containers. Carriers, which have the elements required for processing, such as filling tubes, usually carry out a movement that is adapted to the transport of the containers. The movement of the carrier is usually driven by servo motors. Conventional processing machines often only have limited flexibility and cannot meet the required hygiene requirements in the pharmaceutical, oral-pharmaceutical or cosmetics industry. These are, for example, requirements for as few components as possible, and in particular no motors, which are arranged above openings in the containers. In addition, cleaning the filling elements, such as filling tubes, is often complicated and usually only possible manually. The documents US2011209441A1 , JP2000142890A and DE10246061A1 disclose known devices for handling containers.

Disclosure of Invention

The device according to the invention with the features of claim 1 offers the advantage of an optimized arrangement to meet the highest hygienic requirements. The device also allows, in particular, fully automatic inline cleaning of the product-carrying components, which allows the containers to be processed in a particularly time-efficient and cost-effective manner. According to the invention, this is achieved by a device comprising a carrier with at least one filling element and/or at least one closing element. The filling element is designed for filling a container, and the closing element is designed accordingly for closing the container.

The containers can preferably be filled with the device. For this purpose, the carrier preferably has a filling tube as a filling element, by means of which the containers are filled. Alternatively or additionally, the containers can be closed by a closing element. The closure element can, for example, screw or press closure caps onto the containers. The device can preferably be used in any area in which containers have to be filled and/or closed. Use in the pharmaceutical, oral-pharmaceutical or cosmetic industry or in the food industry is particularly advantageous.

The device also includes at least one cantilever, which is connected to the carrier. The cantilever is connected to a shaft extending along a Z-axis, in particular in a rotationally fixed manner and preferably in an axially non-displaceable manner. The Z-axis is perpendicular to a processing plane in which an opening of the container is arranged. The Z-axis is preferably arranged vertically. The processing level preferably extends in the horizontal direction due to the appropriate arrangement of the container.

The boom can be swiveled around the Z-axis by means of a first motor. Preferably, the cantilever can be pivoted indirectly about the Z-axis, in that the cantilever is non-rotatably connected to the shaft and in that the first motor causes the shaft to rotate. The cantilever can be moved along the Z-axis by means of a second motor. Preferably, the cantilever is translated along the Z-axis indirectly by displacing the shaft using the second motor. Alternatively, the cantilever can be directly translated along the Z-axis by the second motor and relative to the shaft.

Furthermore, the cantilever has a cantilever arm. The cantilever arm can be displaced perpendicularly to the Z axis, in particular linearly, by means of a third motor. The cantilever arm connects the carrier and the cantilever so that they can be displaced relative to one another.

The first motor, the second motor and the third motor of the device are arranged below the processing level. In other words, the first motor, the second motor and the third motor are arranged on a side of the processing plane opposite the carrier. The motors are preferably arranged below a machine table on which the containers are located during handling. In particular, motors or similar elements that perform mechanical work, for example generate torque, are regarded as motors. In particular, gears for setting a target torque can also be regarded as parts of the motor. In particular, however, mechanical elements for transmission, such as shafts or belts, are not included in the engine.

Due to the fact that the motors, and in particular also essential parts of the mechanics required to drive the device, are arranged below the processing level, particularly high hygienic requirements can be met when filling and/or sealing the containers. It can thus be reliably avoided that the containers and/or products filled in the containers become soiled by motors, drive elements or the like arranged above the containers. In addition, the special mechanism of the device results in a particularly favorable and flexible handling of the carrier and the filling and/or closing element arranged thereon. For example, the vertical displaceability of the carrier perpendicular to the Z-axis by means of the cantilever arm can be used to carry out a return movement next to the containers. This prevents, for example after completion of a filling process, that the container or the container contents can become contaminated by product residues dripping down from the filling element. Advantageously, the special mobility of the carrier makes it possible to completely prevent any elements or components of the device from being located above the container opening, for example after a filling process.

The dependent claims show preferred developments of the invention.

The shaft is preferably designed as a hollow shaft and has an internal drive shaft. The internal drive shaft is preferably coaxial to formed radially outer hollow shaft and in particular rotatable relative to this. The drive shaft is connected to the cantilever arm and thus transmits in particular a torque from the third motor to the cantilever arm or preferably to a drive element, which converts a rotation of the drive shaft into a linear movement of the cantilever arm. This results in a particularly simple possibility of arranging the third motor, which drives the horizontal displacement of the carrier, below the processing level.

The extension arm particularly preferably has a toothed belt-driven linear guide, which is preferably provided with a profile rail guide. The linear guide allows linear displacement of the cantilever arm perpendicular to the Z-axis. The linear guide and the drive shaft are in engagement with each other and thus enable a simple transmission of the rotation of the drive shaft and the linear displacement of the cantilever arm.

Preferably, the device further comprises a ball screw, which is driven by the second motor. The ball screw is set up to move the shaft and/or the boom along the Z-axis. For example, an arrangement of the ball screw drive such that it displaces the shaft and thus also the boom arranged thereon with the boom arm and carrier along the Z-axis is particularly favorable. For this purpose, the ball screw drive is preferably arranged on an outer circumference of the shaft. Alternatively, it is preferably also possible for the shaft to be immovable along the Z axis, and for the ball screw drive to cause the boom, which can be displaced relative to the shaft, to be displaced. The ball screw can, for example, have a ball screw shaft which is spatially fixed in relation to the processing plane and extends parallel to the Z axis. A spindle nut of the ball screw drive can be arranged on this ball screw shaft, which is connected to the shaft and/or the extension arm and causes the displacement along the Z-axis when the ball screw shaft rotates. In this case, the ball screw shaft can be directly driven by the second motor, for example.

More preferably, the device includes a torque ball bushing, which is arranged on the shaft. The torque ball bushing is connected to the first motor to particularly prevent pivoting of the shaft about the Z-axis easy way to enable. In particular, the torque ball bushing ensures that the linear displacement of the shaft along the Z-axis is freely possible. The torque ball bushing can be in direct engagement with the first motor or, for example, can also be driven indirectly by the first motor via a gear or a coupling rod.

The carrier particularly preferably comprises a plurality of filling and/or closing elements which are arranged along an X-axis perpendicular to the Z-axis in order to enable the containers to be handled in a particularly time-efficient manner. In particular, only one variant is provided in each case, that is, either a plurality of filling elements or a plurality of closing elements. The carrier preferably has at least 2, preferably at most 20, filling and/or sealing elements. The carrier particularly preferably has 8 or 10 or 12 filling elements. Alternatively or additionally, the carrier preferably has 4, or 6, or 8 closure elements.

Advantageously, the device comprises two cantilevers and two shafts extending parallel to the Z-axis, the two cantilevers each being connected to one of the two shafts, and the two cantilevers each being connected to an axial end of the carrier. The two shafts are preferably each arranged at a predetermined distance from the X-axis. In a particularly preferred manner, the cantilevers are each rotatably connected to the carrier.

More preferably, the device comprises one coupling rod per shaft, which couples the corresponding shaft to the first motor. On the one hand, the coupling rods cause the torque of the first motor to be transmitted to the two shafts in order to rotate them about the Z axis, and on the other hand they synchronize this pivoting of the two shafts.

More preferably, the third motor comprises a belt, the belt connecting the respective cantilever arms of the two cantilevers to allow synchronous displacement of the two cantilever arms. The belt is preferably designed as a toothed belt and is arranged on the axial ends of the shafts opposite the cantilevers, which also particularly advantageously prevents an unnecessarily large number of parts being arranged above the processing plane.

The device preferably also comprises a cleaning device in order to clean the at least one filling and/or closing element. The cleaning device preferably comprises at least one rinsing cup. If the carrier comprises a plurality of filling and/or closing elements, exactly one rinsing cup is advantageously provided for each filling and/or closing element. The flush cup is preferably positioned adjacent to the X-axis when viewed along the Z-axis. The filling and/or closing element is cleaned in particular by the fact that it is immersed in the rinsing cup by appropriately coordinated movements of the device and is rinsed with a cleaning medium. Such a special arrangement of the rinsing cup enables, in particular, fully automatic inline cleaning of the filling and/or closing element without manual intervention. Such a cleaning device is particularly favorable when the filling and/or closing element is designed as a filling tube.

The first motor and/or the second motor and/or the third motor is/are preferably an electric motor, for example a servomotor, in order to enable the device for positioning the carrier to be adjusted particularly easily and precisely.

The device particularly preferably also comprises a transport device which is set up to transport the containers along the X-axis. For example, the transport device can be a conveyor belt. Alternatively, one or more different transport options are possible, such as a rake transport, a screw transport, or a driver transport. A movement of the carrier is preferably adapted in all degrees of freedom to the containers transported by means of the transport device.

• Transportieren einer vorbestimmten Anzahl an Behälter entlang einer X-Achse, und
• Befüllen und oder Verschließen der Behälter.

Furthermore, the invention leads to a method for handling containers with a device described above. The procedure includes the steps:

• transporting a predetermined number of containers along an X-axis, and
• Filling and/or sealing of the containers.

The containers are preferably filled and/or sealed during transport, that is to say while the containers are being transported through the device at a speed that is particularly constant. In the process, containers are particularly preferably transported continuously. Within the device, the predetermined number of containers, in particular at least 10, preferably at most 20, and particularly preferably 8, or 10, or 12, is advantageously always filled and/or closed at the same time. In the method, at least one filling and/or closing element of a carrier of the device, which is assigned to exactly one container, is carried along with the containers during the filling and/or closing. The filling and/or closing element is carried along by a boom of the device connected to the carrier being displaced along a Z-axis and/or by pivoting the boom about the Z-axis and/or by the carrier being vertical is moved to the Z-axis. All three of these movements are particularly preferably carried out simultaneously and are specially coordinated with one another in such a way that the carrier carries out a movement which is optimally adapted to the transport of the containers.

• Zurückfahren des Trägers in eine Ausgangsposition nach dem Befüllen und/oder Verschließen der Behälter.

The method particularly preferably also includes the step:

• Returning the carrier to a starting position after the containers have been filled and/or sealed.

The carrier is retracted with respect to a processing plane next to the X-axis. In other words, the carrier after the filling process and/or the closing process has been completed is displaced perpendicularly to the Z axis in such a way that the carrier, and in particular the filling and/or closing elements of the carrier, when viewed along a direction of the Z Axis are arranged next to the X-axis, then the carrier is moved parallel to the X-axis back to the starting position in order to be able to fill and/or close the next predetermined number of containers. In particular, locating the carrier adjacent to the X-axis equates to locating the carrier at a predetermined retraction distance from the X-axis, the predetermined retraction distance being measured in a direction parallel to the processing plane and perpendicular to the X-axis. Preferably, the predetermined reversing distance is at least large enough for the carrier to be completely outside of a projection that is parallel to the Z axis and aligned with the openings of the container. A soiling of the containers after Completed filling and / or closing can be avoided particularly easily and reliably.

• Reinigen des Füll-und oder Verschließelements des Trägers mittels einer Reinigungseinrichtung.

Preferably, the method further includes the step:

• Cleaning the filling and/or closing element of the carrier by means of a cleaning device.

For cleaning, the carrier is displaced perpendicularly to the Z-axis and, in particular subsequently, displaced along the Z-axis in order to immerse the filling and/or closing element in a rinsing cup of the cleaning device. This means that the rinsing cup of the cleaning device is arranged in particular next to the containers and the cleaning process is also carried out next to the containers. A movement of the carrier from the filling and/or the closing position to the cleaning device can be carried out fully automatically by the device, so that no manual intervention is necessary.

Embodiments of the invention

the figures 1 and 2 show a device 1 for filling containers 10 according to a first embodiment of the invention. the figure 1 shows a snapshot of an operation of the device 1 of FIG figure 1 in the Application in a bottling plant 100. In the figure 2 the device 1 is shown in detail. For reasons of clarity, multiple components that are functionally the same are only identified once with a reference number.

Referring to the figures 1 and 2 First, a description of the structure and the mode of operation of the device 1.

The device 1 comprises a horizontally arranged carrier 2 which has twelve filling elements 21 . The filling elements 21 are designed as filling tubes and are distributed uniformly along an X-axis on the carrier 2 . Each filling element 21 can be used to fill exactly one container 10 with a product during a filling process, for example using a liquid and/or granules.

During operation of the filling system 100, containers 10 are continuously transported in a row, namely along the X-axis and transport direction A, through the device 1 by means of a transport device 8. Container openings 11 of the containers 10 are in a horizontal processing plane 15. In addition, the containers are transported above a machine table 16 of the bottling plant 100. The processing plane 15 and the machine table 16 are thus parallel to one another, with the processing plane 15 in particular being vertically above the machine table 16 at a distance which essentially corresponds to a height of the containers 10 . For the transport of the containers 10, the transport device 8 has a rake transport (not visible in the figures), which pushes the containers 10 in the transport direction A through the device 1.

During transport, twelve containers 10 are filled one after the other by means of the device 1 . For this purpose, the carrier 2 with the filling elements 21 carries out a carrier movement 25 which is optimally adapted to the container transport and which is shown in FIG figure 2 is shown in simplified schematic form.

In detail, before the start of the filling process, the filling elements 21 are immersed in the containers 10 by sliding them downwards parallel to a vertical Z-axis. The containers 10 are then filled with the product via the filling elements 21, during this filling process the filling elements 21 are simultaneously carried along the X-axis with the containers 10 and are shifted upwards parallel to the Z-axis. After the container 10 has been completely filled, the carrier 2 is moved horizontally in which figure 1 indicated by the portion 25a of the carrier movement 25 in order to allow a return movement in the horizontal direction next to containers 10. That is, during the return movement, the filling elements 21 are arranged in such a way that they are arranged completely next to openings 11 of the containers 10 when viewing the device 1 in the direction of the Z-axis. This prevents the contents of the containers 10 and the containers 10 themselves from being contaminated by parts of the device 1 arranged above the openings 11 of the containers 10, ie above the processing level 15 and aligned with the container openings 11.

To fill the next twelve containers 10, the carrier 2 is moved horizontally in the opposite direction following the return movement, characterized by the portion 25b of the carrier movement 25.

In order to enable the carrier 2, in particular the filling elements 21, to be cleaned, the device also comprises a cleaning device 7, each with a rinsing cup 71 for each filling element 21. The rinsing cups 71 are arranged parallel to the X-axis and horizontally next to the containers 10, as in the figure 1 can be seen. To clean the filling elements 21, they can be arranged above the rinsing cups 71 by a corresponding movement of the carrier 2 and then be immersed in them for rinsing the filling elements 21. This so-called inline cleaning is carried out fully automatically by appropriate control of the device 1, and thus without manual intervention of an operator. This enables the containers 10 to be filled in a particularly time-efficient and cost-effective manner, with the highest hygienic requirements being able to be met when the filling system 100 is operated.

An embodiment of the degrees of freedom of the device 1, which enables the above-described handling of the carrier 2 with the filling elements 21, and which further particularly simple advantageously meets the highest hygienic requirements, is described below with reference to figure 2 described.

The carrier 2 is pivotally connected to a cantilever arm 5 at each of its axial ends. The cantilever arms 5 are each part of a cantilever 3 and relative to a boom body 33 of the boom 3 horizontally, ie perpendicular to the Z-axis and along a boom axis 35 displaceable. The horizontal movement portions 25a and 25b of the carrier are made possible in particular by the cantilever arms 5.

For the entrainment movement of the carrier 2 with the containers 10 during the filling, a horizontal displacement of the cantilever arms 5 and a synchronous pivoting of the cantilevers 3 each about a vertical Z-axis takes place at the same time. In order to enable such pivoting about the Z-axis, the booms 3 are each connected to their boom body 33 with a shaft 4 that extends along the Z-axis. The connection between the shaft 4 and the boom 3 is located at one end of the boom body 33 opposite the connection between the carrier 2 and the boom arm 5. The two shafts 4 are also each arranged at a predefined distance 42 from the X-axis, i.e. horizontally from the container openings 11 apart. Shafts 4 and boom 3 are each firmly connected to one another, that is to say non-rotatably and immovably.

Furthermore, the vertical movement of the carrier 2 parallel to the Z-axis is made possible by the shafts 4 and thus also the entire arrangement of shafts 4, brackets 3 and carrier 2 being displaced vertically.

The special design of the drive technology of the device 1, which enables the movements described below with respect to the figure 2 described.

The pivoting of the booms 3 is achieved by driving by means of a first motor 30 and torque ball bushings 32 arranged on the shafts 4, respectively. The torque ball bushings 32 are each connected to the first motor 30 and thus allow torque to be transmitted from the first motor 30 to the shafts 4 to pivot them about the Z-axis. The torque ball bushings 32 allow the shafts to be displaced along the Z-axis relative to the torque ball bushings 32. The torque ball bushings 32 are each connected to the first motor 30 via a coupling rod 43, which means that the shafts 4 and thus the boom 3 can pivot synchronously the Z-axis is possible.

For displacement along the Z-axis, the device 1 comprises a second motor 40 and a ball screw drive 41. The ball screw drive 41 has a ball screw shaft 41a arranged parallel to the Z-axis, which is driven by the second motor 40 via a belt 41b. Furthermore, the ball screw drive 41 has a spindle nut 41c which is arranged on the ball screw shaft 41a and is connected to a beam 45 . In addition, the two shafts 4 are rotatably but immovably connected to the beam 45 . The ball screw drive 41 thus has the effect that when the ball screw shaft 41a is rotated by the second motor 40, the bar 45 and thus also the two shafts 4 and the entire arrangement arranged above are displaced in the direction of the Z axis.

Furthermore, the device 1 for driving the horizontal movement of the carrier 2 by means of the cantilever arms 5 comprises a third motor 50. The third motor 50 drives a belt 53 which is connected to drive shafts 47. The drive shafts 47 are part of the shafts 4. The shafts 4 are each designed as a hollow shaft, with the drive shafts 47 being guided coaxially within the hollow shafts. Due to the fact that the belt 53 is connected to both drive shafts 47, these are rotated synchronously around the Z-axis. The drive shafts 47 are each connected to one of the two cantilever arms 5 . In order to transmit the rotational movement of the drive shaft 47 to the cantilever arm 5 , the cantilever 3 has a toothed belt-driven linear guide 51 which is arranged within the cantilever 3 . The toothed-belt-driven linear guide 51 also has a profile rail guide, which allows a linear and backlash-free displacement of the cantilever arm 5 along the cantilever axis 35 .

Due to the special design of the drive mechanism of the device 1, it is possible to arrange the three motors 30, 40, 50 below the processing level 15, and in particular below the machine table 16, whereby the high hygienic requirements when filling the containers 10 are met and yet all Degrees of freedom of movement of the carrier 2 are made possible. Like in the figure 1 As can be seen, the torque ball bushings 32 pass through the machine table 16, so that all of them are arranged vertically below the torque ball bushings 32, correspondingly below the container 10.

the figure 3 shows a perspective view of a device 1 according to a second embodiment of the invention in use in a sealing machine 200. The second embodiment essentially corresponds to the first embodiment of FIG figures 1 and 2 , wherein alternatively to the filling elements 21 closing elements 22 are provided on the carrier 2, which are designed for closing containers 10. In addition, a movement of the carrier 2, in particular in the vertical direction, is correspondingly adapted to a closing of the container 10. In particular, no vertical movement of the carrier 2 is carried out during the closing process, but only beforehand, for attaching the closing elements 22 to the containers 10, and afterwards.

Nevertheless, it should be noted that tracking of the z-axis, i.e. a movement of the carrier 2 in the vertical direction when the containers 10 are closed, can also be implemented in the device 1 according to the second exemplary embodiment, for example advantageously when there is a thread or the containers are snapped open 10

The closing of the containers 10 is possible, for example, by means of closure caps which are screwed onto the container openings 11 of the containers 10 . This closure cap is fed to the closure elements 22 during the return movement of the carrier (cf. figure 2 ). Otherwise there are essentially the same characteristics and advantages of the device 1 described in accordance with the in connection with figures 1 and 2 described first embodiment.
