Definitions

  • the invention relates to a method for filling prefabricated, relatively rigid containers, with powdery material, with the exchange of a first gas, for. B. air against a second gas, e.g. B. Inert gas.
  • a first gas for. B. air against a second gas, e.g. B. Inert gas.
  • the lid is usually clipped onto the can after being filled with packaging material, i. H. the lid is fixed on the can without sealing it tightly. It is thus possible to remove the air and thus the oxygen with the aid of the vacuum apparatus and to carry out the gassing with inert gas without the packaged goods being able to get into the apparatus from the can.
  • Inert gas purging of relatively rigid containers has proven to be inadequate since the amounts of inert gas that have to be expended are very large are, and yet a relatively large amount of air remains in the container.
  • the object of the invention is to propose a method by means of which the air or the like in the packaged goods or in the pack can be removed from rigid packagings with little expense and labor and exchanged for another gas and, at the same time, the packaged goods can be filled in in doses can.
  • the invention proposes a method in which the first gas is displaced from the container by the filling material and the gas introduced together with the filling material.
  • the packaged goods may have been gassed with the second gas, for example an inert gas, before the actual filling.
  • the second gas can also flow into the packaging container at the same time as the packaged goods. It is also possible to introduce a gas line that is separate from the packaging material into the packaging container, and thus to flush the packaging container with the second gas before loading the packaging material.
  • the main advantage of the method according to the invention is that a vacuum apparatus is completely avoided. It is also not necessary to use high gas velocities so that the mixing of the two gases is suppressed, the gas consumption remains moderate and dust formation is also avoided.
  • a filling device delivering the filling material is lowered to the bottom of the container at the beginning of the filling process.
  • This lowering of the filling device facilitates the relatively gentle stacking of the packaging material from below, the second gas being able to flow into the packaging container at the same time as the packaging material and likewise displacing the air upwards.
  • the filling device moves away from the bottom of the container according to the filling height, i.e. H. So that either the filling device can be raised and lowered, or the packaging container can be moved up and down. In this way it is achieved that the filling material is not or only slightly above the surface of the filling material already filled when it emerges from the filling device. Dusting and the loss of packaging material practically does not occur, and the first gas is displaced from the packaging material in a uniform flow.
  • a displacement body is introduced into the container at the beginning of the filling process.
  • This displacement body which has approximately the shape of the packaging container, displaces the gas in the packaging container before the container is charged with the filling material.
  • the displacement body is expediently firmly connected to the filling device and moves away from the bottom of the container in accordance with the filling height of the filling material.
  • the displacer can either have the shape of a disc, the shape of which is adapted to the packaging container, or it can fill the packaging container entirely.
  • the invention further proposes an invention for carrying out the method, in which a filling device with a filling tube is provided, the mouth of the filling tube being arranged at least at the beginning of the filling process on the bottom of the container.
  • the goods to be packaged flow through the filling tube into the packaging container in a uniform flow.
  • the filling device is then raised or the packaging container is lowered, as it corresponds to the filling height of the goods to be packed, until finally the container is completely filled and the filling device is removed upwards.
  • the filling tube is designed as part of a metering device.
  • the filling tube is designed as part of a metering device.
  • for. B. weighed the corresponding amount of the packaging material on a scale or measured by volume and introduced through the filling tube into the packaging container.
  • the filling tube encloses a screw conveyor.
  • the screw conveyor causes a uniform flow of the filling material, which reduces the inclusion of air in the packaging vessel, and on the other hand, exact metering can also be achieved with the screw conveyor.
  • a controllable closure is attached to the lower end of the filling tube.
  • the controllable closure enables the filling material to be pre-dosed before the packaging container is actually filled. Thereby the workflow can be facilitated and accelerated.
  • Another embodiment consists in arranging lines of the second gas at the mouth of the filling pipe.
  • the second gas is fed directly into the packaging vessel and displaces the first gas, such as the air, upwards before or while the filling material gets into the packaging vessel.
  • the displacement body surrounds the filling pipe and supply lines for the second gas are provided in the displacement body.
  • the filling material is compressed by the displacement body, so it contains less gas.
  • the filling tube 6 of the filling device 3 is lowered almost to the bottom 4 of the container 1.
  • the container 1 receives the filling material 2.
  • the filling material 2 is located in a storage container 9, to which a screw conveyor 7 is connected.
  • the screw conveyor 7 is driven by the shaft 11.
  • the filling material 2 reaches the bottom 4 of the packaging container 1 through the screw conveyor 7 in a uniform flow.
  • the filling device 3 with the filling tube 6 lifts out of the packaging container 1, as it corresponds to the filling level of the filling material 2.
  • Another variant of the method provides that the container 1 is lowered, corresponding to the filling height of the filling material 2.
  • the lowering speed of the container 1 or the lifting speed of the filling device 3 is determined from the speed with which the filling material 2 reaches the container 1 .
  • the container 1 is now filled to the top.
  • the filling device 3 is removed from the container.
  • a lid 12 can be applied to the container 1 and the container 1 can be closed in a known manner.
  • the filled, closed container is replaced by a new, empty one, after which the process is repeated.
  • Fig. 4 shows a further embodiment of the invention with a displacement body 5 in the form of a disk.
  • the disc is in the shape of the container 1, adjusted for example a can.
  • the first gas contained in the container 1 is displaced by the introduction of the displacement body 5.
  • the displacement body 5 is fixedly connected to the filling device 3 and is raised with this in the course of the filling process.
  • the air is further displaced by the introduced filling material 2.
  • the filling material 2 Before the filling material 2 is introduced into the container 1, the filling material can be fed through supply lines 8 (see FIG. 1) in the storage container 9 with a second gas, e.g. such as an inert gas. In this process, already gassed filling material gets into the container 1. By using the displacement body 5, an even more complete gas exchange is achieved.
  • the displacement body 5 also causes the filling material 2 to be compressed.
  • the displacement body 5 'can also, as shown in FIG. have a cylindrical shape that fills the can.
  • lines 10 are provided for the second gas in the displacement body 5 '. These gas lines can open out on the underside of the displacement body 5, or else have an opening in the filling tube 6, which causes the filling material 2 to be gassed again before it exits the filling tube 6.
  • a metering device 20 is shown, at the lower end of which the filling tube 6 is connected.
  • the means for introducing the filling material into the metering device and for metering itself are not shown in more detail.
  • the contents can be measured, for example, using a scale, or can also be determined in terms of volume.
  • valve plate 25 which forms a controllable closure.
  • This valve plate 25 is carried by the rod 22, which runs inside the tube 6 and the metering device 20. By lowering the rod 22, the closure 21 is opened, and the filling material enters the container 1 through the gap 23.
  • the valve plate of the closure 21 can also be designed as a centrifugal plate and driven via the rod 22, which then acts as a shaft. As a result, the filling of the filling material into the container 1 can be accelerated.
  • the closure 21 is designed as a rotatable disk.
  • This disc 27 has sector-like openings 24, and the disc 27 interacts with a substantially similarly designed closure plate 26 which is arranged at the lower end of the tube 6 and also has openings 28.
  • the disc 27 can be rotated by means of the rod 22, for example at a right angle, so that the openings 24 of the disc 27 and the openings 28 of the closure plate 26 come into register, whereby the closure 21 is opened.
  • the invention is particularly applicable when, for example, cans containing powdered foods, e.g. B. with milk products or the like. should be filled. This product should be packed under the exclusion of oxygen in order to exclude the harmful effects of oxygen on the shelf life.
  • the invention is concerned with oxygen through an inert gas, e.g. To replace nitrogen.
  • the invention can also be used when gases other than air or oxygen are to be exchanged for a second gas.
  • the second gas can also have a sterilizing effect, for example, with the aim of keeping the contents sterile for as long as possible.
  • the invention can also be used when exchanging undesired reaction gases for a second gas, or also when it comes to bringing about a reaction with the filling material through the second gas during the closure of the containers.
