Description

Technical area

The present invention relates to a device and a closing device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant with a screw cap.

State of the art

In beverage filling plants it is known to provide closing devices designed for this purpose for closing containers with a screw cap, which are also referred to as closers or screw closers. Such devices for closing a container with a screw cap have a closure receptacle in which a screw cap to be screwed onto a container to close the container can be received. The device is set in rotation around an axis of rotation and is lowered onto the container to be closed perpendicular to the axis of rotation, so that the screw cap comes into contact with the container mouth. As a result of the rotation of the device, the screw cap is screwed on and the container is thus closed by the screw cap.

In particular, two types of devices for closing containers are used in current systems. A widespread type comprises a magnetic coupling which provides a rotary coupling of a drive element of the device, which provides the torque or the rotation, and the lock receptacle. Such magnetic couplings are based on the principle of the hysteresis coupling. In this case, a plurality of magnet elements, which are connected to the drive element in a rotationally fixed manner, are opposed to a plurality of magnet elements, which are connected to the closure receptacle in a rotationally fixed manner. Below a breakaway torque that can be predetermined by the configuration of the hysteresis clutch, torque is transmitted from the drive element to the lock receptacle due to the magnetic force generated between the components by the hysteresis clutch. If the set torque, and therefore the specified tear-off torque, is reached or exceeded, the magnetic holding force between the drive element and the Closure receptacle so that the closure receptacle slips through essentially evenly relative to the drive element. It can thus be ensured that the screw cap is screwed onto the container cap with a predetermined maximum closing torque.

Furthermore, it is known to use a servo motor, by means of which a defined torque can be generated, for specifying the rotation of the closure receptacle. In addition, the movements of the lock holder can be controlled individually via the servo motor.

Devices for closing a container with a screw cap, which have servo motors, are comparatively expensive and are therefore only to be preferred for certain applications. In devices for closing a container with a screw cap, which are equipped with a hysteresis coupling, it can happen that the closure receptacle begins to rotate again as soon as the device is lifted from the container, and therefore removed, as this causes the screw cap and consequently the Container acting pressure force is reduced. This can result in, for example, the container, which is no longer fixed by the spike plates of a star-shaped neck holding the container, being rotated, or the closure receptacle slips over the surface of the screw closure, which is usually provided with teeth. In this way, the container and in particular its neck ring can be scratched. Slipping through of the closure in the closure receptacle can also damage the screw cap and, in the long term, also lead to increased wear on the closure receptacle. A twisting of the container can also be problematic if the container is, for example, a molded bottle and this is to be transported through the system in a directed manner.

Presentation of the invention

Based on the known prior art, it is an object of the present invention to provide an improved device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant with a screw cap, and a closing device for closing containers with a screw cap.

The object is achieved by a device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant with a screw cap, with the features of claim 1. Advantageous further developments result from the subclaims, the description and the figures.

Accordingly, a device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling system with a screw cap, is proposed, comprising a closure receptacle for receiving a screw cap, a drive element for providing a torque about an axis of rotation, and a magnetic coupling for rotary coupling of the drive element and the lock receptacle. The device is further characterized in that a further coupling is arranged between an output element, which is arranged on the output side of the magnetic coupling in relation to the drive element, and the lock receptacle.

Because a further coupling is arranged between an output element, which is arranged on the output side of the magnetic coupling with respect to the drive element, and the lock receptacle, in addition to the decoupling provided by the magnetic coupling, when the tear-off torque is reached, a coupling or decoupling of the lock receptacle can be performed independently of the magnetic coupling and the tear-off torque take place from the output element. In this way, it can be achieved that a torque is only transmitted to the closure receptacle when this is necessary for screwing the screw cap onto the container closure, and then the closure receptacle, even if the tear-off torque is not reached, by the rotational movement provided by the drive element or by that the torque provided by the drive element is set in rotation again.

Consequently, it can be avoided that, after the screw cap has been screwed on, an undesired movement of the container provided with the screw cap is caused by the torque of the drive element. Furthermore, it can be avoided that, when the device is lifted from the container, the closure receptacle slides or slips uncontrollably over the screwed-on screw cap and thereby the closure receptacle and / or the screw cap are exposed to wear.

The terms “drive side” or “drive side” and “output side” or “output side” are to be understood here in relation to a corresponding component in the direction of force flow, with the force flow from the drive element initially to be provided to the torque or the rotation Torque or the rotation extends to the screw cap transmitting closure receptacle.

It has been found to be particularly advantageous if the device is designed in such a way that the coupling and decoupling or decoupling of the further coupling is applied by means of the device when the screw cap is screwed onto the container mouth Contact pressure is controlled. The pressing force can correspond to the force applied by the closure receptacle to the container closure in the closing direction, with which the closure receptacle is pressed onto the container in the screwing-on direction.

The contact pressure of the device, controlled for example by a lifting curve, with which the device is pressed in the direction of the axis of rotation when the screw cap is screwed onto the container mouth, can be used, for example, to couple the further coupling when it is placed on the container mouth.

The device is preferably also designed in such a way that when the device is lifted from the closed container or from the screw cap screwed onto the container, the further coupling is decoupled due to the resulting reduced contact pressure.

According to a preferred embodiment, the further clutch has a drive part arranged on the drive side and a driven part arranged on the driven side, the driven part and the drive part preferably each having a coupling area for mechanical coupling with the coupling area of the other part, the coupling areas preferably being designed in the form of a toothing are. In this way, reliable coupling and decoupling of the further coupling can be achieved in a simple manner.

According to a further embodiment, the further coupling has a drive part arranged on the drive side and a driven part arranged on the driven side, the driven part and the drive part preferably each having a coupling area for mechanical coupling with the coupling area of the other part, the coupling areas preferably being in the form of a magnetic or electromagnetic pairing are formed. In this way, reliable coupling and decoupling of the further coupling can be achieved in a simple manner.

The driven part and the drive part are preferably arranged so as to be displaceable relative to one another between a coupled position and a decoupled position in the direction of the axis of rotation. In the case of electromagnetic pairing, the power supply can also be terminated in order to achieve a decoupled position.

According to a further preferred embodiment, the drive part is rotatably coupled to the output element, preferably the drive part with the output element by means of a Toothing is rotatively coupled or the drive part and the output element are integrally formed.

Alternatively or additionally, the driven part can be rotatably coupled to the closure receptacle, the driven part preferably being rotatively coupled to the closure receptacle by means of a toothing or the driven part being formed in one piece with the closure receptacle.

In order to achieve a particularly small installation space for the device, the drive element can be arranged radially outside the output element at least in the area of the magnetic coupling with respect to the axis of rotation.

If the drive part is arranged radially inside the output element in relation to the axis of rotation, this contributes to a simple construction of the device with a comparatively small installation space.

According to a further preferred embodiment, a bushing extending in the direction of the axis of rotation in the drive part is provided, the bushing being guided in the direction of the axis of rotation on the drive part, the driven part being essentially fixed to the bushing in the direction of the axis of rotation and the driven part being attached to the bushing is rotatably mounted about the axis of rotation, preferably by means of a roller bearing, particularly preferably by means of a ball bearing, and wherein the bushing has a stop arranged relative to the drive part opposite the driven part for striking on the drive side against a stop surface of the drive part. In this way, a particularly rigid structure of the device can be achieved in a simple manner, so that it can be possible to place the screw cap on the container mouth with a high degree of accuracy.

A distance in the direction of the axis of rotation between the stop and the coupling area of the driven part is preferably larger than a distance in the direction of the axis of rotation between the stop surface and the coupling area of the drive part. As a result, a range of movement of the output part relative to the drive part can be provided which allows the output part and the drive part or their coupling regions to be disengaged by moving the coupling regions away from one another in the direction of the axis of rotation. The stop limits the maximum possible distance between the coupling areas.

In order to be able to achieve a particularly simple construction and a stable structure of the device, the bushing can extend radially inside the drive part in relation to the axis of rotation, the stop being designed as a radially outwardly directed projection.

Alternatively or additionally, the output part can be arranged radially outside the bush.

According to a further preferred embodiment, a spring is provided for biasing the further clutch into the decoupled position in which no torque can be transmitted via the further clutch. In this way it can also be achieved that when the device is lifted from the container mouth after the screw cap has been unscrewed, the spring tension of the spring causes the container to continue to be pressed onto a container holder, for example a spike plate, for a short additional period of time, thus also securing against rotation of the container.

According to a further preferred embodiment, a stop disk is arranged in the closure receptacle for transmitting a contact pressure to a screw cap held in the closure receptacle during a closing process.

It has been found to be advantageous if the closure receptacle has a closure cone for transmitting the torque provided by means of the drive element.

The object set above is also achieved by a closing device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant with a screw cap, with the features of claim 12. Advantageous further developments of the closing device emerge from the present description and the figures.

Accordingly, a closing device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant with a screw cap, is proposed, comprising a container holding device for holding a container, preferably for holding a container on its retaining ring. The closing device is characterized by a device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant with a screw cap, according to one of the preceding embodiments.

Because the closing device has a device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant with a screw cap according to one of the preceding embodiments, the advantages and effects described with regard to the device can be achieved in an analogous manner by the closing device .

The configurations, features, advantages and effects described with regard to the device also apply to the locking device without this being described again redundantly, and vice versa.

Detailed description of preferred exemplary embodiments

Preferred exemplary embodiments are described below with reference to the figures. Identical, similar or identically acting elements are provided with identical reference symbols in the different figures, and a repeated description of these elements is in some cases dispensed with in order to avoid redundancies.

In Figure 1 a sectional view through a device 1 for closing a container 18 with a screw cap 17 is shown schematically. According to this embodiment, the container 18 is a beverage container in the form of a PET bottle, which is provided for filling a beverage in a beverage filling plant. The device 1 comprises a closure receptacle 2 for receiving a screw closure 17 to be applied to the container 18. It further comprises a drive element 3, which provides a torque or a rotation about an axis of rotation 4, and a magnetic coupling 5 for the rotative coupling of the drive element 3 and the lock holder 2.

The magnetic coupling 5 is constructed in a manner known per se on the principle of the hysteresis coupling. It comprises a plurality of magnetic elements arranged in the circumferential direction around the axis of rotation 4 on an output element 6, which face a hysteresis ring made of non-magnetized permanent magnet material on the drive element 3, wherein in the area of the magnetic coupling 5, the drive element 3 is arranged radially outside of the output element 6 in relation to the axis of rotation 4 is. The magnetic coupling 5 provides an essentially slip-free torque transmission below a predetermined breakaway torque. Above the tear-off torque, the drive element 3 rotates relative to the output element 6.

The device 1 also has a further coupling 7, which is arranged between the output element 6, which is arranged on the output side of the magnetic coupling 5 in relation to the drive element 3, and the lock receptacle 2.

The further clutch 7, viewed in the direction of force flow, provides the output side of the output element 6, the possibility of decoupling the lock receptacle 2 from a torque provided by the drive element 3 or from a rotation additionally provided to the drive element 3 independently of the magnetic coupling 5.

For this purpose, the further clutch 7 has a drive part 8 arranged on the drive side and a driven part 9 arranged on the driven side, the driven part 9 and the drive part 8 each having a coupling area 80, 90 for mechanical coupling with the coupling area 90, 80 of the respective other part. In the present case, the coupling regions 80, 90 are designed in the form of a tooth system. In other words, the coupling region 80 has a plurality of teeth and the coupling region 90 has a plurality of teeth designed to correspond to the teeth of the coupling region 80.

The output part 9 and the drive part 8 are in the direction of the axis of rotation 4 relative to one another between a coupled position in which the coupling areas 80, 90 intermesh and thus provide a torque transmission, and a decoupled position in which the coupling areas 80, 90 are disengaged thus providing no torque transmission, displaceable. In Figure 1 the further clutch 7 is shown in the decoupled position.

According to this embodiment, the driven part 9 is integrated in one piece into the closure receptacle 2. In other words, the closure receptacle 2 has the coupling area 90.

To transmit torque between the output element 6 and the drive part 8, a toothing 10 is provided between them, the output element 6 being arranged radially outside of the drive part 8 with respect to the axis of rotation 4.

To implement the further coupling 7, according to this optional embodiment, an optional bush 11 extending in the direction of the axis of rotation in the drive part is provided, the bush 11 being guided in the direction of the axis of rotation 4 on the drive part 8. The drive output part 9 is in turn essentially fixedly mounted on the bushing 11 in the direction of the axis of rotation 4 and rotatably mounted about the axis of rotation 4 by means of a ball bearing 13. Furthermore, the bushing 11 has a stop 12, which is arranged with respect to the drive part 8 opposite the driven part 9, for striking a stop surface 82 of the drive part 8 on the drive side.

The socket 11, the drive part 8 and the driven part 9 are designed such that a distance in the direction of the axis of rotation 4 between the stop 12 and the coupling area 90 of the driven part 9 is greater than a distance in the direction of the axis of rotation 4 between the stop surface 82 and the coupling area of the drive part 80.

According to this embodiment, the bushing 11 extends radially inside the drive part 8 with respect to the axis of rotation 4, the stop 12 being designed as a radially outwardly directed projection. Furthermore, the driven part 9, and therefore the closure receptacle 2, is arranged radially outside the bush 11.

In the according to Figure 1 As shown in the decoupled position of the further coupling 7, the locking receptacle 2 can rotate about the bushing 11 via the ball bearing 3. If the further coupling 7 is moved into the coupled position in which the coupling regions 80, 90 mesh with one another, the lock receptacle 2 rotates together with the drive part 8 and the driven element 6 mechanically rotatably coupled to it.

An optional spring 14 extending within the socket 11 in the direction of the axis of rotation 4 biases the further coupling 7 into the decoupled position. For this purpose, the spring 14 is supported on the drive side, thus against the driven part 9 or the locking receptacle 2, on the driven element 6, and the spring 14 is supported on the socket 11 on the driven side. As a result of its pretension, the spring 14 presses the bushing 11 and the driven part 9 or the locking receptacle 2 away from the drive part 8 in relation to the direction of the axis of rotation 4, so that the coupling regions 80, 90 are disengaged.

In the closure receptacle 2 there is also a stop disk 15 for transmitting a contact pressure to the screw cap 17 held in the closure receptacle 2 during a closing process arranged. In addition, the closure receptacle 2 has a closure cone 16 for receiving the screw closure 17 with an essentially precise fit and for transmitting the torque provided by means of the drive element 3.

According to this embodiment, the container 18 is held on a retaining ring 20 arranged on the container 18 below the container mouth 19 from below by means of a spike plate 21 provided with spikes 22.

The further clutch 7 is always held in the decoupled position by the spring 14. If the device 1 is lowered onto the container 18 to be closed held by the spike plate 21 in the direction of the axis of rotation 4, there is initially contact between the screw cap 17 and the container mouth 19 of the container 18 1 applied pressing force the bias of the spring 14, the drive part 8 is moved in the direction of the output part 9 until the coupling areas 80, 90 come into engagement and thus the further clutch 7 comes into the coupled position. From this point in time, the torque provided by the drive element 3 or the rotation provided by the drive element 3 can be transmitted to the screw closure 17 by means of the closure receptacle 2, so that the screw closure 17 is screwed onto the mouth area 19 of the container 18.

If the friction torque between the threads of the screw cap 17 and the container mouth 19, which corresponds to a closing torque of the screw cap 17 to be achieved, reaches the level of the tear-off torque of the magnetic coupling 5, the drive element 3 rotates mechanically relative to the output element 6 and the drive part 8 and with the latter output part 9 coupled by means of the further coupling 7.

If the device 1 is lifted again from the container 18 after the container 18 has now been closed with the screw cap 17, the closure receptacle 2 is initially still pressed against the screw cap 17 due to the spring 14. The coupling regions 80, 90 are thereby disengaged. Accordingly, it can be achieved that with a decreasing friction torque between the closure cone 16 and the screw closure 17 due to the decreasing contact pressure on the screw cap 17, there is no rotation of the closure receptacle 2 due to a torque transmission by means of the magnetic coupling 5 if the aforementioned torque falls below the level of the tear-off torque.

Furthermore, by means of the spring 14, the container 18 with its retaining ring 20 continues to be pressed against the spike plate 21 for a short period of time, which can provide additional protection against rotation of the container 18.

Out Figure 2 FIG. 11 is a schematic sectional view of a portion of the device 1 from FIG Figure 1 can be seen which shows the further coupling 7 in the decoupled position in detail.

In the decoupled position, the socket 11 strikes with its stop 12 against the stop surface 82 of the drive part 8, as described above, so that the coupling regions 80, 90 are out of engagement. As described above, the distance between the stop 12 and the coupling area 90 is larger than the distance between the stop surface 82 and the coupling area 80. As a result, there is a gap 23 between the driven part 9 and the drive part 8, which is greater than the tooth height of the coupling areas 80, 90 .

In Figure 3 FIG. 11 is a schematic sectional view of the further coupling 7 from FIG Figure 2 shown in the coupled position. Here, as already described above, the driven part 9 is moved towards the drive part 8 against the bias of the spring 14, so that the coupling regions 80, 90 are in engagement with one another. Accordingly, the gap 23 is present between the stop 12 and the stop surface 82.

Figure 4 shows the device 1 again with the further coupling 7 in the coupled state, as in detail Figure 3 refer to.

Figure 5 shows schematically a sectional view through a closing device 100 for closing containers 18 with a screw cap 17. The closing device 100 is embodied in the present case in a rotary design. It has a rotating carousel, comprising a container holding device 110 for holding containers 18 and a plurality of devices 1 for closing a container 18 with a screw cap 17 according to the embodiment described above.

The container holding device 110 has a plurality of spike plates 21 for holding a container 18 on its holding ring 20, each of the spike plates 21 being assigned to a device 1.

The devices 1 are arranged on the closure device 100 such that they can be moved in the direction of the axis of rotation 4, so that a distance between the device 1 and the container 18 held on the respective spike plate 21 can be changed by moving the device 1 along the axis of rotation 4.

In the Figure 5 The device 1 shown on the left is held in a raised position in which it can take over a screw cap 17 from a cap transfer device 120 of the closing device 100. The device 1 shown by way of example on the right in FIG. 6 is on its associated container 18 lowered to this as with respect to Figures 1 to 4 described to close with a screw cap 17.

As far as applicable, all the individual features that are shown in the exemplary embodiments can be combined with one another and / or exchanged without departing from the scope of the invention.
