Definitions

  • the invention relates to a filling system for filling powder into a filling container to be sealed of the type specified in the preamble of claim 1 and a method for filling powder in a target container by means of such a filling system.
  • Certain powders such as detergent powder are prepared as loose bulk material and then metered by means of a metering device in specified subsets. The dosed subsets are then filled into a destination container.
  • target containers may be film packages of water-soluble film containing a unit dose of the powder for later use by the end user.
  • packaged in water-soluble film unit boxes are intended to be inserted into the washing machine. Upon contact with the washing water, the film packaging dissolves and releases the intended amount of washing powder.
  • the metering device is usually positioned above the upwardly open target container, so that the metered subset of the powder falls as a result of the force acting force in the open, later still to be sealed target container. This forms a loose bulk cone, which must not exceed a certain height. If the height level of the powder cone is kept low, the target container can not be filled to the brim. At a higher Schüttkegel that extends beyond the level of container sealing surface is the subsequent sealing process endangered. The bulk cone is then contrary to the application of the réellesiegelnden cover sheet. Powder can get on the sealing surface, which affects the quality of the subsequent sealing. A full utilization of the container volume is therefore not possible.
  • a filling system with a hopper is known, the outlet pipe is guided into the target container.
  • the target container is set in vibration, which should favor a compaction of the powder to be filled.
  • the invention has the object of developing a generic filling system such that an improved degree of filling of the target container is possible.
  • the invention is further based on the object of specifying a method for filling powder in a target container, by means of which the available container volume can be better utilized.
  • a compression element for the powder is arranged, wherein the compression element for the filling process can be lowered from above to the target container.
  • the powder is first metered by means of the metering device and filled in the direction of weight force from above into the target container open at the top.
  • the advantages of the invention come in particular for carrying a filling system, which comprises a transport chain for receiving and transporting the target container.
  • a conveyor chain in particular designed as a plate chain
  • an influence on the powder does not take place on the container side, but from above by means of the compression element, which is arranged below the metering device and therefore during the filling process between the metering device and the target container.
  • the compression element By means of the compression element, either the formation of a bulk cone is prevented or such a bulk cone - if present - leveled.
  • the compacting element is designed as a vibrating element with a vibrating drive, wherein the vibrating element protrudes at least partially from above into the target container during the filling process.
  • the compression element designed as a vibrating element is lowered from above to the target container so that it at least partially protrudes from above into the target container.
  • the vibrating element is vibrated by means of its vibrating drive.
  • the powder in the target container is subjected to vibration without causing the container itself to vibrate.
  • the formation of a bulk cone is prevented.
  • any powder pour cone that may be present can be made uniform to a flat, free powder surface. In both cases, the shaking also leads to a compaction of the powder in the target container, so that the available container volume can be optimally utilized.
  • the compression element is designed as a pressing element with a pressing surface facing the open side of the target container.
  • the pressing element is lowered with its pressing surface onto the free surface of the powder in the target container. This also results in a good compaction of the powder and the formation of a flat as possible, uniform free surface achieved.
  • a hopper is formed. This ensures that filling, compaction and surface homogenization can go hand in hand, while keeping the sealing surface of the target container free of powder.
  • a particular conical distribution surface is formed in the compression element. This distribution surface is particularly effective in connection with the pressing element, in that despite the presence of a pressing surface a uniform powder filling is achieved in the target container.
  • the filling system has a cover for the sealing edge of the target container. This provides additional security that, due to the compacting and homogenizing process described above, no powder can reach the sealing surface or the sealing edge.
  • Fig. 1 shows a schematic sectional view of a first embodiment of the filling system 1 according to the invention for filling powder 2 in a target container 3.
  • the target container 3 is an example of a trough-shaped deep-drawn water-soluble film, which is sealed later after the filling with a cover film, not shown .
  • the powder 2 is an example of a washing powder.
  • the filling system 1 comprises a metering device 4, a compression element 5 arranged below the metering device 4 with respect to the direction of the weight force, a receptacle for the target container 3 to be sealed, which in the exemplary embodiment shown is designed as a schematically indicated transport chain 16, a cover 14 and also during operation the target container 3 itself.
  • the transport chain 16 is executed in the embodiment shown as a plate chain. To illustrate the invention are in Fig. 1 only simplifies a target container 3, an associated compression element 5, an associated cover 14 and an associated portion of the metering device 4 shown with a metering hole 19.
  • a plurality of target containers 3 arranged in the form of a row or a matrix are filled at the same time, to each of which a separate metering bore, each having its own cover 14 and its own compacting element 5, is assigned.
  • the compression elements 5 can be combined to form a common compression plate. The same applies to the covers 14th
  • the filling system 1 is provided for filling powder 2 into the target container 3, which is still open during the filling process and later to be sealed.
  • the powder 2 provided as loose bulk material in a storage container, not shown, is first metered into intended partial quantities by means of the metering device 4.
  • the metering device 4 is designed as a volumetric metering device with a metering slide 18, wherein in the metering slide 18 at least one, here several metering holes 19 are introduced.
  • the metering holes 19 have a fixed volume which corresponds to the desired metering volume of the powder 2.
  • the metering slide 18 is positioned so that the metering bore 19 comes to lie below the storage container for the powder 2, as a result of which the powder 2 falls into the metering bore. Subsequently, the metering slide 18 is displaced laterally according to an arrow 20, whereby a partial amount of the powder 2 is metered into the metering bore 19, and whereby this metered subset comes to rest above the target container 3 to be filled. In this case, the metered subset of the powder 2 falls due to the force acting down from the metering 19 and out into the target container 3, as in Fig. 1 is shown. In the upwardly open, not yet sealed state of the target container 3, an upper, free surface 17 of the powder 2 forms in this case.
  • a compression element 5 is provided, which is based on the direction of the weighting force below the metering device 4 and during the filling process between the metering device 4 and the target container located underneath 3 is arranged.
  • the compression element 5 is designed as a vibrating element 6 with a vibrating drive 7.
  • the vibrating element 6 can be offset according to a double arrow 22 in a horizontal and lateral vibration or vibration. In the context of the invention, however, other forms of vibration come into consideration.
  • the metering device 4, the compression element 5 and a cover 14 described in more detail below together form a structural unit which is assigned to a single target container 3 to be filled.
  • This assembly of metering device 4, compression element 5 and cover 14 is positioned in the overall machine not shown in more detail at a stationary filling station, while the target container 3 by means of the transport chain 16 from station to station, ie in particular to said filling station and also to a separate, not shown Siegelstation be moved.
  • the transport chain 16 is continuously moved together with the target containers 3 held thereon.
  • the above-mentioned "stationary positioning" of the filling station here means that it or its assembly of metering device 4, compression element 5 and cover 14 only during the dosing, filling, compression and homogenization process in synchronism with the transport chain 16 and held thereon Target containers 3 moved and then based on the direction of the transport chain 16 is returned to its original position. There then begins a new cycle of dosing, filling, compression and homogenization process on a new set of target containers 3.
  • the filling station or its described parts do not run continuously, but only over a short, for the dosing, filling , Compaction and equalization process required path with the transport chain 16 with. But it can also be a clocked expiration expedient.
  • the transport chain 16 is stopped together with the target containers 3 held thereon at the individual stations, ie in particular at the filling station and the subsequent sealing station, where then takes place in the dormant state of dosing, filling, compression and homogenization process or the subsequent sealing process ,
  • the method according to the invention described here is carried out analogously in the same way both in continuous operation and in clocked operation of the transport chain 16.
  • the target containers 3 are initially positioned below the dosing and filling unit described above. Said unit including the compression element 5 and the cover 14 is then lowered according to an arrow 21 from above to the target container 3 out.
  • the target container 3, in the still-open state shown, has an upwardly directed circumferential sealing edge 15 onto which a cover film is later sealed.
  • the cover 14 is placed on the sealing edge 15, so that the sealing edge 15 is covered and can not come into contact with powder 2.

  • the vibrating element 6 projects at least partially from above into the target container 3 in that a corresponding part of the vibrating element 6 comes to lie below the sealing edge 15 in the interior of the target container 3 and within the metered and filled powder quantity.
  • the filling process performed in this state of the filling system 1 is composed of two sub-processes which can be performed sequentially, simultaneously or overlapping in time.
  • the first sub-process is the filling of the powder 2 through the Verdiekchtungselement 5 through into the target container 3, as described above subsequently to the dosing.
  • In support of this ein Anlagende sub-process is performed in the vibrating element 6 as a compression element 5, a hopper 12 with a bottom circumferential edge 8. Through the hopper 12, the falling down from the top of the metering hole 19 powder 2 2 is directed through the compression element 5 purposefully into the target container 3.
  • the second sub-process of filling consists in a compression of the powder 2 located in the target container 3 to form a uniform, at least approximately flat, free surface 17 by means of the compacting element 5.
