Description

 DEVICE FOR FILLING A CONTAINER

Technical area

The present invention relates to a device for filling a container with a

Filling product, preferably for filling a container in a beverage filling plant and a filling device for filling a filling product into a container.

PRIOR ART It is known to bring the container to be filled and the filling valve into sealing contact with each other when bottling beverages. This is especially necessary when bottling carbonated drinks. The sealing contact is achieved by pressing the container to the filling valve or by pressing the filling valve to the container.

For pressing the container to the filling valve is known to raise the container to be filled in the direction of a fixed height mounted filling valve. However, this has the disadvantage that a container to be filled can only be lifted after the container holding the container holder of a filling device from the region of the container holder of the inlet star, which passes to be filled container to the filling device, driven as usually the container holder the filling device at the transfer of the container below the

Container holder of the inlet star is arranged. In addition, the container holder of the

Filling device be lowered before it enters the area of an outlet star bracket, to which the filled container is handed over.

Filling devices in which the containers to be filled are raised accordingly have a reduced treatment angle, which has adverse effects on the performance or the possible throughput of such filling devices. Nevertheless, in order to achieve a high throughput, such filling devices are very large form, resulting in high manufacturing and operating costs. The strokes of the container lifting and lowering staples of the filling devices are about lifting curves controlled, which are given by arranged on the stationary part of the filling device guide curves. The pressing cylinder of the staples of the filling devices, however, are arranged on the rotating part of the filling devices.

During operation of the filling device, this results in a swelling force load between the stationary and the rotating part of the filling device. To be able to absorb these loads permanently, such filling devices are correspondingly massive

training, which in turn increases the manufacturing and operating costs.

In order to overcome the aforementioned disadvantages, it is known that on a rotating

Lowering valve carrier arranged filling valves for filling the container on the container and to keep the container itself but at a fixed height. In such a trained

 Filling devices, the clamps for holding the container are firmly connected to the valve carrier.

Since the filling valves and the clamps are connected at different positions on the valve carrier, there is an unfavorable distribution of force flux and moment distribution during pressing. In particular, during pressing, contact forces which are transmitted as bending moments to the valve carrier occur. So filling valves, valve carrier and container holders are to their

Compensation accordingly massive.

Presentation of the invention

Starting from the known prior art, it is an object of the present invention to provide an improved apparatus for filling a container with a filling product, preferably for filling a container in a beverage filling plant.

The object is achieved by a device for filling a container with a filling product, preferably for filling a container in a beverage filling plant with the features of claim 1. Advantageous developments emerge from the subclaims. Accordingly, an apparatus for filling a container with a filling product, preferably for filling a container in a beverage filling plant is proposed, comprising a support pin, a fastened to the support bolt filling member, which along a

Has longitudinal axis of the filling member relative to the carrier bolt movable filling valve, and a rigidly fixed below the filling valve to the carrier bolt container holder for holding a container to be filled. According to the invention a connection device for height-adjustable attachment of the carrier bolt to a transport device, preferably provided on a valve carrier, a filling device in a beverage filling plant.

As a result of this structure of the device, the force flow which occurs during pressing no longer extends over the valve carrier, but is closed within the device. The contact forces that act when pressing the filling valve on the recorded in the container holder container are introduced on both sides directly into the carrier bolts and absorbed by this. In other words, the force flow during pressing only runs between the filling valve, filling member, container holder and carrier pin. Since the filling member and the container holder are mounted directly on the carrier bolt, and the resulting lever arm over which the contact forces on the filling valve and on the container holder resulting contact forces are introduced to the carrier bolt is short. Accordingly, the bending moment on the

Carrier pin low and thus an inclination of container and filling valve relative to each other negligible. The transport device of the filling plant is therefore of the by the

Pressing the filling valve on the forces acting in the container holder container forces decoupled and can be constructed correspondingly less massive.

Furthermore, since the attachment device is designed to be height-adjustable for height-adjustable attachment of the carrier bolt to the transport device, the attachment device is designed to be height-adjustable. Thus, the height of the carrier pin relative to the transport device of the filling device can be adjusted so that the height level of the attached to the carrier bolt container holder corresponds to a predetermined height in the filling device. The height adjustment is done only by changing the height of the carrier bolt relative to the transport device. Thus, the distance between filling member and container holder, which are both attached directly to the carrier bolt, always the same. In other words, given an adjustment of the predetermined by the height-adjustable connection device

Connection position or connection height of the carrier bolt a parallel

Displacement of filling member and container holder, both of which are fixedly secured to the carrier bolt. Consequently, the distance between the filling valve and the container holder remains the same, so that all parameters relating to the control of the contact pressure and the resulting filling behavior are independent of the height position. In this way, the device can be designed to be particularly efficient.

Furthermore, any existing rash of the transport device, as

for example, the valve carrier, via the height adjustment by means of the connection device be compensated. Thus, a particularly reliable construction of a filling device can be achieved because possible height tolerances can be compensated, which could possibly affect the adoption behavior of the container holder. In other words, all container holders can be set to exactly the same height, without the container carrier would have to be aligned very precisely.

Furthermore, the filling member can also be preassembled as a preassembled module and later in the form of this module by means of the connection device to the transport device, preferably attached to the valve carrier. In this respect, it is possible to pre-assemble already all the pneumatic and / or hydraulic switching functions and filling functions of the device and their hoses and to check the function of the preassembled device before it is installed in the filling device.

In order to allow a particularly simple and accurate adjustment of the height of the carrier bolt relative to the transport device, the attachment device according to another preferred embodiment, at least one adjusting nut with an adjusting thread provided on the support bolt in engagement. The carrier bolt is supported by means of the adjusting nut on the transport device from above, thus in the direction of gravitational acceleration. Turning the adjusting nut on the adjusting thread causes a displacement of the adjusting nut in the longitudinal direction of the bolt. Consequently, the carrier pin also experiences a displacement relative to the transport device according to the displacement of the adjusting nut. Preferably, two adjusting nuts are provided, wherein a first adjusting nut acts from a first side of the connecting device and a second adjusting nut of one of the first

Adjusting nut opposite side of the connection device acts. The second

Adjusting nut acts as a lock nut, so that the carrier pin is clamped to the transport device and the device can thereby be fixed in a fixed position relative to the transport device.

According to a further preferred embodiment, the attachment device has a clamping plate for rigid attachment to the transport device, wherein preferably the

Height adjustment of the carrier pin relative to the clamping plate takes place. As a result, a simple and secure installation of the filling element is achieved on the transport device. Furthermore, the filling member including height adjustment can be preassembled. In particular, if the height adjustment is provided by the provision of an adjusting nut or preferably two adjusting nuts, the adjusting nuts on the clamping plate can cause the height adjustment. In order to specify the position of the filling member relative to the transport device transversely to the vertical direction, the attachment device according to another preferred

Embodiment an alignment member for aligning the device on the transport device perpendicular to the longitudinal axis seen on, preferably a groove element and / or a spring element and / or a pin.

When the filling member and the container holder according to another preferred

Embodiment are arranged on the carrier bolt such that when pressing the filling valve to a container held in the container held by the pressing forces and / or moments are absorbed by the carrier bolts, a particularly secure filling of the container to be filled can be achieved. The forces acting on pressing forces are then absorbed directly by the carrier bolt. In other words, the filling member is fixedly mounted on the carrier pin in one area or one side of the carrier pin, and the container holder is fixedly mounted on the carrier pin on another area or on another side of the carrier pin. The forces acting on the container when the filling valve is pressed are then also introduced directly into the carrier bolt through the connection of the filling member directly into the carrier bolt and through the connection of the container holder. Consequently, then the conclusion of the power flow in the carrier bolt.

The above object is further achieved by a filling device for filling a filling product into a container having the features of claim 6. advantageous

Further developments will become apparent from the dependent claims and the present description and the figures.

Accordingly, a filling device is proposed for filling a filling product into a container, comprising a valve carrier rotatable about a central axis of rotation and at least one device for filling a container with a filling product according to one of the preceding embodiments.

By means of the filling device, the advantages described for the device for filling a container with a filling product are achieved analogously. Brief description of the figures

Preferred further embodiments of the invention are described by the following

Figure 1 shows schematically a side view of a filling device for filling a filling product into a container;

FIG. 2 is a schematic sectional view of a device for filling a container with a filling product of the filling device from FIG. 1;

FIG. 3 schematically shows a sectional view of a connection device of the device from FIG. 2; and FIG. 4 schematically shows a detailed view of a valve carrier of a filling device according to a further embodiment.

Detailed description of preferred embodiments

In the following, preferred embodiments will be described with reference to the figures. In this case, identical, similar or equivalent elements in the different figures are provided with identical reference numerals, and a repeated description of these elements is partially omitted in order to avoid redundancies.

1 shows schematically a side view of a filling device 100 for filling a filling product into a container, not shown here, which is to be filled. The filling device 100 may be, for example, in a filler carousel in a beverage filling plant for filling drinks into beverage containers.

The filling device 100 comprises a valve carrier 104 which can be rotated about a central axis of rotation 102 and which can form, for example, a filler carousel, and a plurality of devices 1 for filling a container with a filling product. The devices 1 are held around the circumference of the filler carousel, for example, on the valve carrier 104. The devices 1 are respectively connected via media lines 108 to a central media rotary distributor 106, from which the devices 1 are connected respectively to the process media and to the

Be supplied filling product. The media lines 108 are each with process connections a process media plate 34 of the devices 1 connected. By providing the

Process media plate 34, all process connections can be arranged in a plane.

FIG. 2 schematically shows a sectional view of a device 1 for filling a container with a filling product of the filling device 100 from FIG. 1. The device 1 comprises a carrier pin 2, a filling member 3 fastened to the carrier pin 2, which is relatively long along a longitudinal axis 32 of the filling member 3 to carrier pin 2 movable filling valve 30, and a rigidly fixed below the filling valve 30 to the support pin 2 container holder 4 for holding a container to be filled. The

Container holder 4 may be provided for example in the form of a passive or active clamp.

To fill a container to be filled this is held on the rigidly fixed to the carrier pin 2 container holder 4 and the filling valve 30 is lowered relative to the carrier pin 2 on the container to be filled, so that the filling can be performed with pressed filling valve 30. The device 1 further comprises a height-adjustable attachment device 5, by means of which the carrier pin 2 is connected to the valve carrier 2 of the filling device 1 adjustable in height.

The attachment device 5 has a clamping plate 52 which is rigidly secured to the valve carrier 104. The carrier pin 2 is, as will be described in detail below with reference to Figure 3, through a bore 54 of the clamping plate 52 and by means of two adjusting nuts 50, 50 'in the direction of the bolt longitudinal axis 22, and thus in its height relative to the clamping plate 52 and thus in its height relative to the valve carrier 104, held in a fixed position.

The contact forces that act on a filling in the container holder 4 container on the filling valve 30 and the container holder 4 at a pressing of the filling valve 30 are introduced on both sides directly into the carrier pin 2 and received by this. In other words, the force flow during pressing only runs between the filling valve 30 or filling member 3, the container holder 4 and the carrier pin 2. Since the filling member 3 and the container holder 4 are mounted directly on the support pin 2, which is between the longitudinal axis 32 and Bolt longitudinal axis 22 forming lever arm over which the contact forces generated at the filling valve 30 and the container holder 4 contact forces are introduced to the carrier pin 2, short. Accordingly, the bending moment on the Carrier pin 2 low. The valve carrier 104 is thus decoupled from the forces acting on the container located in the container holder 4 by the pressing of the filling valve 30 and correspondingly less solid.

FIG. 3 schematically shows a sectional view of the connection device 5 of the device 1 from FIG. The clamping plate 52 is pinned by means of alignment elements (not shown) in the form of pins with the valve carrier 104 and screwed by means of screws 56.

As already mentioned with regard to Figure 2, the Anbindungsvornchtung 5 two adjusting nuts 50, 50 ', each of which is provided with an adjustment provided on the support bolt 2 adjusting thread 20, 20' in engagement. A first adjusting nut 50 acts from a first side of the Anbindungsvornchtung 5 on the clamping plate 52 of Anbindungsvornchtung 5 and a second adjusting nut 50 'acts from one of the first adjusting nut 50 opposite side of the clamping plate 52 on the clamping plate 52 a.

The carrier pin 2 is supported by means of the first adjusting nut 50 on the clamping plate 52 from above, thus in the direction of gravitational acceleration. The second adjusting nut 50 acts as a lock nut, so that the carrier pin 2 is clamped to the clamping plate 52 and thereby fixed in a fixed position.

The provided by the Anbindungsvornchtung 5 height adjustment of the carrier pin 2 via a rotation of the first adjusting nut 50, wherein the second adjusting nut 50 'must be previously solved to solve the above-described strained state. The rotation of the first adjusting nut 50 on the adjusting thread 20 causes a displacement of the adjusting nut 50 in the direction of the bolt longitudinal axis 22. Consequently, the carrier pin 2 experiences relative to

Clamping plate 52 a displacement in the direction of its bolt longitudinal axis 22, which the

Displacement of the adjusting nut 50 corresponds.

By the aforementioned adjustment of the support pin 2 in its height relative to the clamping plate 52, the height of the support pin 2 can be adjusted relative to the valve carrier 104, so that the height level of the attached to the carrier pin 2 container holder 4 corresponds to a predetermined height of the container holder 4 in the filling device 100 , The height adjustment takes place solely by changing the height of the carrier pin 2 relative to the clamping plate 52

or to the valve carrier 104. Thus, the distance from filling member 3 or filling valve 30 and container holder 4 to each other remains the same, since both are attached directly to the support pin 2. In other words, in an adjustment of the height-adjustable Connection device 5 predetermined connection position or connection height of the carrier pin 2 a parallel displacement of filling valve 30 and container holder. 4

FIG. 4 schematically shows a detail view of a valve carrier 104 according to a further embodiment. For connecting a device for filling a container with a filling product as described with reference to FIGS. 2 and 3, a connection 10 is provided on the valve carrier 104. The carrier pin 2 can be pushed for connection from the outside into the connection 1 10. The clamping plate can then by means of pins, which are inserted into fitting holes 1 14 of the valve carrier 104, pinned and by means of the screws, which are screwed into provided therefor threaded holes 1 12 of the valve carrier 104, are attached.
