Definitions

  • the invention relates to a metering device for pourable, especially powdery material, with a feed shaft, a vertical to the lower end of the feed chute Filling pipe and one arranged at the lower end of the filling pipe, displaceable in the longitudinal direction of the filling pipe by means of a shaft Closing cone that in an open position Releases the annular gap at the lower end of the filling tube and in one Closed position on a ring surface or ring edge on the bottom The end of the filling pipe.
  • the the coarse filling causes a metering device to be used which can only generate one dosing flow for fine dosing, or a dosing device with a filling device for the Combine coarse filling, which is setting different large openings for coarse filling and fine dosing.
  • a problem with fine dosing is that powder Materials tend to bridge in narrow exit openings form, where appropriate, even at a high ballast Weight to prevent material from flowing off. Especially if the material is sticky in consistency as it is with Goods in the food sector such as cocoa powder, milk powder or the same is the case, it can be assumed that a reliable Drain in free flow from a narrow opening to the Fine dosing is practically impossible.
  • the present invention has the object based on providing a metering device that also poorly flowing materials in a fine stream for fine metering can measure.
  • the solution to this is a dosing device which is characterized in that the closing cone a slope on an upward-facing cone surface having blading and that the closing cone for Conveying material through the annular gap using the blading can be driven to rotate by the shaft.
  • a first embodiment of the device according to the invention can go that a device for fine dosing only is created that is independent of a system for the coarse filling is used.
  • a device be chosen with a relatively short filling tube, because the one to be attached Sack is already mostly filled when it is from a rough filling station coming in the dosing station if required is pulled over the filling pipe.

  • the locking cone can be lowered up to a point where the cross-sectional area of the annular gap is almost the cross-sectional area corresponds to the filling pipe.
  • the closing cone has a second counter cone surface on its underside, which the Closing surface forms and in a deepest position against a reducing the free cross section of the filling tube, in particular inner conical counter surface.
  • the closing cone is preferably adjusted by that the shaft firmly connected to a drive motor for the locking cone together with this opposite the frame and the feed chute.
  • a first actuating cylinder is preferably which is fixed, the path between the open position with a large annular gap and the metering position with cause a small annular gap and at least a second Actuating cylinder made up by the first actuating cylinder in total is moved, the stop of the sealing cone on the ring edge or ring surface for the closed position.
  • two first and second actuating cylinders diametrically opposite each other in the ratio shaft of the locking cone.

  • On the filling tube 57 is a Welded connection ring 70, the one with an end ring 71st is connected by means of a union nut 72.
  • an inner ring 73 is welded in, the inner one Ring surface 65 forms.
  • the lower cone surface 67 sits on this of the closing cone 63 sealingly, while the upper conical surface 66 carries only the blading 64.
  • annular gap in this version by pulling shaft 62 upwards open.
  • the annular gap is open in the position shown the delivery rate that is suitable for fine dosing is set.
  • the material is rotated by means of the Blading promoted through the annular gap. This device is only intended for fine dosing.
  • the shaft 62 is within the hopper 52 through the Guided hollow shaft 84 and emerges from this hollow shaft 84 free out. There it is connected via a bearing 89 to a connector 83 an actuating cylinder 81 connected.
