Definitions

  • the invention relates to a device for filling sacks with a clamping device holding the flat sacks in the region of their opening edges and side edges, with suction cups engaging and pulling them up on opposite sides in the region of the opening edges, and with a filler neck which is parallel to one another by a drive device Axes in opposite directions swiveling hopper halves is provided.
  • the object of the invention is therefore to provide a device for filling sacks of the type specified at the outset, with which sacks can be filled essentially dust-free.
  • this object is achieved in a device of the type specified at the outset in that the swivel axes of the filling funnel halves run transversely to the line connecting the gripping devices and in that the expansion plates of the filling funnel halves have essentially convex profiles, the apex of which, in mirror image, pointing outwards, on that connecting the gripping devices Line.
  • the profiled spreading plates in the area of the gripping devices can sealingly rest against the edge of the sack spanned by the filling funnel halves, so that the opening cross section of the spreading filling funnel halves essentially corresponds to the profile of the spanned sack opening.
  • the clamping devices which usually consist of pliers, are at a constant distance from one another when the bags are gripped, so that the bag openings spanned by the filling funnel halves have the same size even with bags of different widths. Since the filling funnel halves fit well against the inner wall of the opened sack opening in their spread state, no channels remain through which dust could escape in a disruptive manner. Since the gripping tongs pinch off the side areas of the opening sides of the sacks to be filled, sacks provided with gussets can be filled in the same way as sacks without gussets with the device according to the invention.
  • the profiles of the expansion plates can have an approximately circular or elliptical shape or can be formed by the legs of an isosceles triangle.
  • the spreading plates shaped in this way can be swiveled close to the gripping devices without inadmissibly high tensions occurring in the edge region of the opened sack.
  • the side edges of the profiled sheets are connected to sheets of the filling funnel halves which are parallel to the pivot axes and which delimit channels with the profiled sheets. These channels can be covered to prevent dust from escaping, or they can also be connected to suction channels so that dust can be sucked off through them during the filling process.
  • the filling speed can be increased significantly if the opening of the filling funnel halves can be started immediately with the filling of the clamped sack and does not have to be waited until the inflow to the filler neck is released after the filling funnel halves have spread.
  • the two halves 1, 2 of the funnel are mounted on a support piece 21 which can be fastened to the filling tube or a frame so as to be pivotable about axes and shafts 7, 8 which are parallel and horizontal to one another.
  • the two hopper halves 1, 2 have an essentially U-shaped cross section and are arranged in mirror image to one another.
  • the side walls 1.1 and 1.2 of the hopper half 1, the cross section of which can be seen in FIG. 2, partially overlap the corresponding side walls of the other hopper half 2 in the pivoted-in position and in the pivoted-out position over their entire height, as shown in FIG. 1 in the extended and dash-dotted lines is shown.
  • Suction pipes 5, 6 are attached to the rear walls 1.3 of the hopper halves 1, 2. In their lower area, which dips into the sacks to be filled, these have the cross section of an isosceles triangle, the length of the base of this isosceles triangle corresponding to the width of the rear wall of the filling funnel halves 1, 2. In the lower area of the hopper halves, the suction tubes 5, 6, which are triangular in cross section, are connected to them. Above their triangular cross-sectional area, the suction pipes 5, 6 change their cross-section and these are connected to a suction pump via flexible pipes, not shown.
  • a lever 10 is rotatably attached, at the free end of the piston rod of a pneumatic cylinder 9 is articulated.
  • the hopper half 2 can thus be pivoted.
  • the pivoting movement to the other half of the hopper 1 is angled to the lever 10 on the shaft 8 a further lever 22.
  • one end of a coupling rod 11 is articulated, the other end of which is articulated to the free end of the lever 12 which is fastened on the shaft 7 pivoting the hopper half 1.
  • the pneumatic cylinder 9 can thus simultaneously pivot both filling funnel halves 1 between their swiveled-in position, shown in solid lines, and their swung-out filling position 1 ', 2', 5 ', 6', shown in broken lines.
  • Fig. 3 the filling funnel halves in their pivoted-in position 1, 2 and their pivoted-out position 1 ', 2' are shown schematically in a section along the line III-III - in FIG. 1.
  • the lower ends of the filling funnel halves 1, 2 are pivoted from the position shown in full lines in FIG. 3 by confirming the pneumatic cylinder 9 into the position 1 ', - 2' and at the same time the suction air of the suction devices 19, 20 is switched off, so that the filling funnel halves pull the opening edge of the sack apart in the manner shown in FIG.
