Definitions

  • the invention relates to a bag-filling machine in which made the medium with compressed air flowable and is supported by an F üllrschreibe, having a storage cylinder having at its bottom with a ventilation openings, formed from at least three segments, inclined towards the stuffing tube sieve-like bottom is completed and in the peripheral wall above the bottom, the filling tube is attached.
  • Such bag filling machines which work with the pneumatic conveying principle, have been known for many years and are used in practice for filling bags with dusty goods.
  • the sieve-shaped base serves to loosen the filling material through the air flow, so that it becomes fluid and can get into the filling tube.
  • a sack filling machine of the type mentioned at the outset is known, the bottom of which is inclined towards the filling tube and is divided into six segments, two of which are arranged one behind the other in the direction of the inclination.
  • a common compressed air line is applied to the segments.
  • the six segments each have an air inlet opening, so they only serve to distribute the compressed air over the surface of the floor. The problem of emptying residual quantities is not addressed in this publication.
  • the invention has for its object to provide a bag filling machine of the type mentioned, which ensures a significantly improved flow of the pneumatically conveyed filling material and at least leads to a reduction in the remaining filling quantity contained in the filling tube and in the storage cylinder.
  • This object is achieved in that at least three segments are arranged one behind the other in the direction of the inclination of the floor and that under the segments sealed from each other, a separate compressed air supply chamber is arranged, which are each provided with a controllable compressed air supply.
  • the setting of the pressure for the different segments - including the relative setting of the pressure of the segments among one another - depends on the respective filling material.
  • the optimum setting can easily be determined experimentally by a person skilled in the art.
  • At least four segments are arranged one behind the other on the line between the filling tube and the wall of the storage cylinder opposite the filling tube.
  • An optimal result in practice is achieved when the floor is inclined and the angle of inclination is between 10 ° and 45 °, preferably approximately 20 °.
  • the flow guidance is particularly favorable if the segment which lies directly in front of the filling tube has approximately the width of the filling tube and the width of the segments arranged one behind the other increases conically with increasing distance from the filling tube.
  • the side segments should be inclined obliquely to the center segments arranged one behind the other, so that a channel that tapers conically to the filling tube is formed, which is formed from the center segments arranged one behind the other and the side segments, whereby the side segments can also be divided into a plurality of side segments arranged one behind the other or next to one another .
  • the underside of the filling tube is arranged in alignment with the top of the bottom. This creates a step at the transition between the floor and the filling tube avoided, as was the case with conventional filling machines.
  • the filling pipe is connected to a through hole in the wall of the storage cylinder, the opening cross section of which is essentially identical to the cross section of the filling pipe. It has surprisingly been found that any nozzle-like design of the transition from the supply cylinder to the filling tube leads to a deteriorated flow.
  • the filling tube has a cross section with a width that is substantially greater than its height.
  • the ratio of width to height is preferably about 2: 1.
  • the filling pipe has its greatest width at its bottom, for example it is semicircular or preferably rectangular.
  • the emptying of the filling tube is further promoted in that the filling tube is arranged inclined downwards.
  • the inclination of the filling tube can preferably correspond approximately to the inclination of the bottom on the line between the filling tube and the wall of the storage cylinder opposite the filling tube.
  • the filling machine shown in Figure 1 has a support frame 1 to which a bag chair 2 is attached as part of a weighing device. With the movable with the sack chair; Arrangement is connected to a filling tube 3, which opens into a storage cylinder 4 held on the frame 1.
  • the storage cylinder is completed at its lower end with a sloping floor 5.
  • On the underside of the base 5 there are a large number of compressed air lines 6 in FIG recognizable with which compressed air is directed to different locations of the floor 5 divided into several areas.
  • Locking device 7, which separates the storage cylinder 4 from a feed line 8 to a storage silo (not shown) for the filling material.
  • the filling tube 3 is surrounded at its front end, onto which a valve of a valve bag is inserted, with an inflation hose 9, which ensures a seal between the filling tube 3 and the valve of the valve bag, so that the dusty filling material is not blown out.
  • the bag placed on the filling tube 3 is fixed in a known manner on the filling tube 3 by means of a pneumatically controlled stamp 10 which presses on the filling tube from above.
  • the air pressure supplied via the compressed air lines 6 can be adjusted with the aid of setting controllers 7, depending on the application, a separate setting controller 7 for each compressed air line 6 or also a setting controller 7 for a subset of compressed air lines 6.
  • Figure 2 shows schematically that the filling tube 3 has a rectangular cross section in the illustrated embodiment.
  • the first segment 11 which is adjacent to the filling tube 3
  • All segments 11 widen conically to the wall of the storage cylinder 4 opposite the filling tube 3, so that they form a conically tapering path towards the filling tube 3.
  • the segments 11 adjoin one another and are inclined downwards towards the filling tube 3 with respect to the horizontal.
  • the first segment adjacent to the filling tube 3 has a lower inclination than the other segments 11, which are all inclined equally and continuously connect to each other.
  • the inclination of the segment 11 adjacent to the filling tube 3 is adapted to the inclination of the filling tube 3, as shown in FIG. 3b.
  • the segments 11 arranged one behind the other are supplemented laterally by side segments 12 to form the complete floor 5.
  • the side segments 12 adjoining on both sides of the segments 11 are inclined laterally to the segments 11 arranged one behind the other.
  • Four side segments are provided on each side of the segments 11, the dividing lines 13 of which are approximately perpendicular to the direction pointing towards the filling tube 3 from the side segments 12.
  • the segments 11 arranged one behind the other, together with the laterally rising side segments 12, form an approximately U-shaped channel in cross section, the upstanding legs of which diverge obliquely upwards.
  • Each of the segments 11, 12 has on its underside a pressure chamber 14 (see FIGS. 1 and 3b) which are sealed off from one another and each have their own compressed air supply line 6. This ensures that the air flowing through the sieve-like segments 11, 12 of the base 5 can be regulated for each segment 11, 12 relative to other segments 11, 12.
  • the compressed air supply line 6 is expediently provided with a separate setting regulator 7 for each segment 11, 12.
  • the suitable setting of the setting regulator 7 for each segment 11, 12 allows an adaptation to the respective filling material.
  • various setting combinations can lead to optimal fluidization and thus to an optimal flow of the filling material through the storage cylinder 4 and the filling tube 3.
  • the storage cylinder 4 has a wall 15, in which there is a through opening 16 which is flush with the cross section of the filling tube 3.
  • the bottom of the filling tube 3 is flush with the top of the relevant bottom segment 11, so that on the underside of the filling tube 3 there is a continuous transition between the bottom 5 and the underside of the filling tube 3. Otherwise, the passage opening 16 leads to sharp-edged transitions with respect to the wall 15 of the storage cylinder 4. A nozzle-like expansion to create a gradual transition has therefore been avoided.
  • Figures 4 and 5 also show an air discharge line 17 on the underside of the filling tube 3 below the rectangular cross section and a compressed air supply line 18 on the top of the filling tube, which opens into a chamber 19 surrounded by the inflation hose 9 and therefore causes the inflation hose 9 to inflate.
  • a compressed air supply line 23 is also arranged, which ends below a bottom part designed as a sieve 24 with two ventilation segments and thus produces a fluidized bed on the bottom for complete residual emptying.
