Definitions

• the invention relates to a method for filling containers with a liquid product, which is supplied to the container via a filling valve and a filling nozzle.
• the invention further relates to a device for filling containers with a liquid product, which has at least one filling valve and at least one filling nozzle.
• Such filling devices and methods are known in various embodiments, for example for filling Kartonageverpak- kungen or bottles.
• An essential goal in the implementation of filling process is a fast and reliable filling of the container. To realize a quick filling, it helps if foaming during the filling process can be avoided or reduced as much as possible.
• a problem in the filling of containers with non-circular cross-sectional area results from the fact that the distances of the inner walls to a generally centrally arranged filling nozzle are different depending on the respective solid angle and thereby a foaming is supported.
• the object of the present invention is to improve a method of the aforementioned type such that rapid filling of containers with a non-circular cross-sectional area is supported.
• This object is achieved in that the leaking from the filling material is fed to a guide element, which is provided with a geometric shape such that an edge of the guide extends inside with a small distance along walls of the container.
• Another object of the present invention is to construct a device of the initially mentioned type such that a filling of containers with a non-circular cross section is supported.
• a guide element is arranged, which has a design such that an edge of the guide element on the inside and with a small distance to an inner wall of the container to be filled can be arranged.
• the inventive method and the device according to the invention are particularly suitable for filling beverage cartons.
• Such beverage cartons are opened during the filling process in the region of their extent, which is still oriented upwardly in the vertical direction, and are sealed only after completion of the filling process. It is thus possible in a simple manner to introduce the guide element according to the invention in the upper region of the interior of the container.
• the material flowing along the guide element is passed against the inner wall of the container and can flow evenly here.
• a design of the Leitele- Mentes can also be taken to ensure that a uniform distribution of the contents takes place in such a way that substantially the same volume rates of contents are supplied to all areas of the inner circumference of the container. This supports fast, even and low-foam filling.
• the uniform distribution of the contents over the entire area of the inner surface of the container leads to a significant reduction in the flow rate of the filling material. Due to the uniform sliding of the filling material on the inner wall of the container, the impact velocity of the filling material is reduced to the bottom of the container and with progressive filling on the surface of the already filled contents, which also reduces the formation of foam.
• the guide element according to the invention can be used both with stationary clocked filling devices and with filling devices with rotating filling wheels.
• a uniform supply of the filling material into the container interior is assisted by the fact that the guide element is used as a diffuser.
• a drainage of the filling material on the inner wall is supported by the fact that the filling material is guided by the guide element obliquely to the horizontal direction against the wall of the container.
• a continuous transfer of the contents of the guide element to the inside of the wall of the container is also supported by the fact that the distance is chosen such that the filling material flowing over the edge of the guide element reaches into the region of the inside of the side walls of the container.
• An appropriate dimensioning is that a distance of at most 15 mm is selected.
• an aseptic filling of the filling material is carried out.
• a typical filling of non-round containers is defined by filling a container made from a cardboard material.
• a uniform implementation of the filling process is also achieved in that the contents are prevented with baffles on the guides of the container edges, whereby the displaced from the interior of the container air is discharged to the container edges upwards.
• the air discharge elements are positioned in the region of corners of the guide element.
• a hollow-bore valve stem also allows quick venting during the filling process.
• the packing interior is purged with inert gas, such as nitrogen, through the valve stem prior to filling to reduce oxygen in the headspace.
• FIG. 1 is a schematic partially sectioned view of a filling device with associated portion of a container to be filled
• FIG. 2 is a perspective view of the guide element with additional air discharge elements
• Fig. 3 is a perspective view for illustrating a flow of the filling material via the guide element to the inside of the container and
• FIG. 4 is a side view of the arrangement of FIG .. 3
• Fig. 1 shows a schematic partial and sectional view of a filling device (1).
• the filling device (1) has a connecting line (2) for connection to a supply, not shown, of a liquid filling material.
• the connecting line (2) via a manifold (3) with a valve seat (4) is connected, which is provided for receiving a filling valve, not shown.
• the valve seat (4) is connected via a valve manifold (5) with a nozzle (6).
• a shaft (7) In a longitudinal direction of the nozzle (6) extends a shaft (7), which is generally hollow and thereby allows gas exchange in the package interior before and during the filling process.
• a guide element (9) In a direction of flow (8) below the filling nozzle (6), a guide element (9) is arranged which has an edge (10).
• the geometric design of the guide element (9) and in particular the course of the edge (10) are adapted to a cross-sectional area of a container to be filled (11), of which in Fig. 1, only a portion is shown.
• the guide element (9) Starting from one of the filling nozzle (6) facing the central kingdom (12) of the guide element (9), the guide element (9) extends in the direction of the edge (10) with a direction opposite to the vertical direction arranged slope and in the region of the edge (10) with a Distance (13) to an inner side (14) of the side walls of the container (11).
• the filling nozzle (6) and the guide element (9) are covered by a hood (15), in particular to support aseptic filling of the filling material.
• the air discharge elements (18) are preferably arranged in the region of corners (19) of the guide element (9). In the area of their central area (12) facing extension the air discharge elements (18) are provided with baffles (20).
• the air discharge elements (18) can be designed as an open towards the inside (14) of the container (12) profile. It is also possible to use open hollow profiles in the vertical direction.
• FIG. 2 shows a perspective view of the guide element (9) and the filling nozzle (6) arranged above the guide element (9).
• the guide element (9) for the filling of a substantially provided with a square cross-sectional area container (11) is formed.
• the guide element (9) has a surface profile (21) such that a uniform supply of the filling material to the inner sides (14) of the container (11) is supported.
• each air discharge elements (18) are arranged such that they rise like a column over the edge (10).
• Fig. 3 illustrates the performance of a filling process. From the filling nozzle (6), the filling material (22) exits and impinges on the guide element (9). By the guide element (9), the filling material (22) is guided uniformly in the direction of the inner sides (14) of the container (11) and can run evenly on these inner sides (14). 4 illustrates the filling process according to FIG. 3 in a side view. Again, the extremely uniform flow of the filling material (22) on the inner sides (14) can be seen.
