Definitions

  • the invention is based on a filling device for valve bags, in particular, in which a centrifugal wheel driven by a vertical axis of rotation and loaded with bulk material from above is provided in a supply housing, the supply housing having a filler neck, which is assigned to the circumference of the centrifugal wheel and laterally outgoing, for introducing the bulk material into has the attached valve bag.
  • a further device is provided with a centrifugal wheel driven about a vertical axis of rotation.
  • this centrifugal wheel is preceded by a control device which consists of a central metering cone on the centrifugal wheel and a vertically adjustable cylinder slide which is coaxial with it.
  • the inlet cross-section to the centrifugal wheel can thus be reduced and enlarged in order to achieve an approximately uniform inflow of the medium into the centrifugal wheel, depending on the density and the moisture of the filling material.
  • the full filling capacity of the centrifugal wheel cannot generally be used. This is only possible when the cylinder slide is fully retracted, which, on the one hand, only occurs in a few cases and, on the other hand, the increased possibility of error of the tolerance-exceeding bag filling remains in any case.
  • the object of the invention is to improve a filling device of the type mentioned above in such a way that, with optimal filling of the centrifugal wheel, an increased filling capacity of the device and compliance with the filling tolerances during the filling process with respect to the respective container used is achieved.
  • the solution to the problem is that, starting from a filling device of the type mentioned at the outset, the centrifugal wheel is preceded by a feed device which forcibly fills this wheel.
  • This feed device can preferably consist of a screw which can be driven about a vertical axis of rotation.
  • the first exemplary embodiment shown in FIG. 1 comprises a funnel-like feed housing 1, a feed device 2 provided in its lower region, a centrifugal wheel 3 adjoining it below, and a filler neck 4 adjoining the lower end of the feed housing 1 in the usual way, which extends from the side Housing 1 goes off and is arranged substantially tangentially to the circumference of the centrifugal wheel 3.
  • a container indicated by dashed lines is attached to the filler neck 4 and is to be filled and preferably consists of a valve bag.
  • the feed device 2 preferably consists of a worm that can be driven about a vertical axis of rotation 6, which in the illustrated case is single-start, but can also be multi-start.
  • the centrifugal wheel 3 is also driven to rotate about a vertical axis, it being possible for both the centrifugal wheel 3 and the worm 2 to be arranged on a common shaft 7, as shown.
  • a preferably electric drive motor 8 drives the shaft 7.
  • the motor 8 is preferably mounted on the lower wall 9 of the feed housing 1. In this case, the centrifugal wheel 3 and the worm 2 are driven at the same, possibly variable speed.
  • the screw 2 can also be driven at a different speed, which differs from the speed of the centrifugal wheel 3.
  • Such an embodiment will essentially be chosen if the contents to be processed with the proposed device vary very greatly in consistency and / or density, which e.g. depends on the degree of moisture and / or the degree of fluidization of the filling material.
  • the filling usually consists of powdery or fine-grained material, e.g. Cement, lime and other prepared powder material for building; but it also includes appropriate material from other areas, such as milk powder.
  • a realization of a different speed in relation to that of the centrifugal wheel 3 can be achieved in that a further drive motor 10 is provided, the shaft 11 of which extends through the shaft of the first-mentioned motor 8 and through the mentioned shaft 7.
  • the shaft 7 is hollow and ends with the centrifugal wheel 3, so that the worm 2 is then arranged on the shaft 11 which protrudes from the shaft 7 above the centrifugal wheel 3.
  • the different speed of the screw 2 can also be realized in a different way.
  • a drive shaft can protrude into the feed housing from above and have the worm 2 at its lower end, while the upper end of this shaft is provided with the motor 10, in a manner that does not hinder the entry of the filling material into the feed housing.
  • the two drive motors 8 and 10 can each be speed-controlled, so that a corresponding, optimal speed can be selected in adaptation to the filling material to be filled in the valve bag 5.
  • FIG. 2 shows a further exemplary embodiment, which differs from the first exemplary embodiment in that the screw 2 is preceded by a further device 12 which consists of paddle-like stirring arms.
  • These agitator arms are arranged on the shaft 7 or 11, which also carries the screw 2, at a circumferential distance from one another.
  • the agitator arms 12 are also spaced apart from one another in the axial direction, so that they are located on an imaginary helical line running around the shaft 7 or 11, as shown in FIG.
  • a plurality of stirring arms can also be provided in different levels, the stirring arms of one level preferably being offset from the stirring arms of the adjacent level.
  • the radially projecting stirrer arms 12 themselves can also be angularly adjustable about their longitudinal axis, so that different angles of attack of the paddle-like stirrer arms are possible depending on the product being conveyed.
  • the procedure can also be such that the screw 2 is omitted and instead only the paddle-like stirring arms 12 are provided in a corresponding number and desired arrangement.
  • the paddle-like stirring arms 12 will be provided if there is a fear in the conveyed filling material that segregation of the filling material can occur.
  • the agitator arms 12 in addition to their axial conveying work, develop a mixing effect on the filling material.
  • the angular adjustability of the agitator arms also loosens or compresses the filling material, depending on how it is necessary for the optimal feeding of the filling material.
  • a cellular wheel sluice 13 is used instead of the screw 2 as the feed device provided that can be driven about a horizontal axis of rotation 14.
  • Cellular wheel locks are generally known in their structure and function, so that the cellular wheel lock 13 is not explained in detail.
  • the filling material can be metered into the centrifugal wheel 3 with the cellular wheel sluice. This embodiment will be chosen if the product tends to press more or less.
