Definitions

  • the invention relates to a bag filling machine with a unit having a conveyor belt for supplying the medium to be bagged and with a filling pipe.
  • the conveyor belt is an element of a centrifugal belt filling element and in this case interacts with a flywheel in which a U-shaped channel is formed on the outside.
  • the outer circumference of the flywheel lies against the centrifugal belt, so that a closed cross section is formed which binds the feed cross section.
  • the centrifugal belt and flywheel are driven at high speed and accelerate the material to be fed, which is then conveyed into the sack in a free jet through the filling tube.
  • Filling machines of this type are used for the filling of fillings of gritty to lumpy structures, for example of finer products, for example in the type of white sugar via fertilizer granules to animal feed or shredded compacts (US-A-19 79 483 and 26 05 990).
  • centrifugal belt filling element In filling machines with a centrifugal belt filling element, mechanical stress on the filling material is inevitable. In addition, there is a risk of segregation when filling goods that are of different sizes. Finally, the transition between the centrifugal belt filling element and the filling pipe is problematic in terms of sealing.
  • the object of the invention is to provide a filling machine with which the product can be filled with high filling performance and almost without mechanical stress.
  • the conveyor belt or a plurality of conveyor belts is arranged for conveying the goods in the filling tube so that their downstream deflection is in the region of the filling tube mouth and in each case the returning run of the conveyor belt runs inside the filling tube.
  • the filling pipe may be expedient to provide the filling pipe with at least two conveyor belts which are guided on different cross-sectional wall surfaces of the filling pipe.
  • the conveyor belts can be guided on two opposite wall surfaces.
  • the conveyor belts can be guided converging at least over a partial area downstream.
  • the filling tube itself can, for example, be arranged essentially vertically.
  • the filling tube can be provided with an inclined inlet shaft, on the lower and upper wall of which a conveyor belt is guided.
  • a continuous conveyor belt can be provided for the upper walls of the filling pipe and the inlet shaft.
  • the conveyor belts are each slidably guided on a guide plate and deflected around a rounded end edge of the guide plate at the downstream end.
  • a filling element 2 is shown with a filling funnel 4, to which a filling pipe 6 connects horizontally, on which a valve bag 8 can be plugged in for filling in the usual way.
  • the bottom of the filling funnel 4 is formed by a conveyor belt 10, which extends with its downstream end to the front edge of the filling tube 6, ie to the mouth 12 thereof.
  • the conveyor belt 10 is guided on a metal plate 14 and guided around a rounded edge 15 of the metal plate 14 at the downstream end. At the upstream end, the conveyor belt 10 extends beyond the rear wall 16 and is guided there around a drive roller 18.
  • the conveyor belt is guided around a tensioning roller 20, which holds the returning run 22 of the conveyor belt once parallel to the underside of the metal plate 14 and is also adjustable in the direction of the arrow to adjust the tension of the conveyor belt if such a tensioning option is not in the storage of the Drive motor for the drive roller 18 is provided.
  • the metal plate is disposed within the filler tube 6 so that it bears against the side walls thereof. It can be held by screws which are passed through the straight sections of the side walls of the filling tube.
  • the conveyor belt can be a fabric belt coated or impregnated with a polyurethane with a wall thickness, for example between 0.8 and 1.5 mm.
  • Such belts have a high elasticity and a low coefficient of friction, so that they can be guided around small radii without being exposed to rollers. Such belts still work reliably with semicircular deflections with a radius of 3 mm.
  • the conveyor belt can be driven at speeds of up to 2 m / s and accordingly conveys the material accumulating in the hopper 4 with a high conveying capacity into the valve bag 8 placed on the filling tube.
  • the material largely rests on the one running in the direction of the filling tube mouth Conveyor belt. Friction only occurs outside of the cone of bulk against the side wall of the filling pipe. The goods are thus transported in a dormant manner to the mouth without mechanical stress. The goods are therefore only mechanically stressed to a negligible extent. Due to the stationary transport, there is no segregation.
  • the underside of the conveyor belt can be cleaned in the area between the tensioning roller 20 and the drive roller 18, for example by means of a suction tube 24 which is introduced into this intermediate space, which can optionally be supplemented by a brush or the like.
  • the space can of course also be expanded for this purpose by a further deflection roller.
  • the filling pipe is shown firmly connected to the filling funnel.
  • the filling tube can be formed separately from the filling funnel.
  • the guide plate 14 for the conveyor belt 10 can also be interrupted in the separation area.
  • the filling tube 26 here has a V-shaped bottom with the two bottom sections 28, on each of which a conveyor belt 30 is guided.
  • the two bottom sections 28 merge into a web 33 in the area of their connection.
  • the entire arrangement is enclosed by a filling tube jacket 32, the upper section 34 of which can be bent.
  • the entire good weight lies on the two conveyor belts.
  • the lower edges of the conveyor belts can rest against a guide bar 36 on the inside.
  • Corresponding guide strips can also be provided on the outside of the base plates.
  • the conveying cross section 38 of the filling tube 40 which is here essentially triangular, can also be provided on its upper side with a conveyor belt 42.
  • the material in the filling cross section 38 is thus enclosed on all sides by walls moving in the conveying direction.
  • the upper conveyor belt can also be designed so that a certain compression of the material is achieved.
  • the conveyor belt 42 can be guided at its downstream end to converge over a partial area to the other conveyor belts.
  • the fill tube 44 here has an essentially square cross section.
  • a guide plate 46 is arranged on the bottom analogously to the guide plate 14 in the embodiment according to FIGS. 2 and 2.
  • the guide plate 46 here forms the web of a U-shaped cross section with legs 48, which in turn are designed as guide plates, on each of which lateral conveyor belts 50 are led.
  • the side guide plates 48 can, as shown, lie at right angles to the base plate 46, but they can also be inclined outwards or inwards.
  • the embodiment according to FIG. 5 has the advantage that for a given extent, which is generally given through the filling opening of a paper bag, for example through the valve opening, a larger conveying cross section can be achieved compared to the embodiment according to FIGS. 3 and 4.
  • the conveyor cross section is enclosed on all sides by conveyor belts, analogously to the embodiment according to FIG.
  • the fill pipe 52 is again square here.
  • Conveyor belts of the type mentioned above are highly elastic and can also be guided around curved edges. It is possible, for example, to design the guide plate in the embodiment according to FIG. 1 to be curved downward in cross section in order to achieve more favorable filling tube cross sections in this way. Due to the high elasticity of the conveyor belt, the guide plate, as shown in Fig., Can also be U-shaped with a half circular bottom. The shape of the cross section of the conveyor belt 54 is determined here by the deflecting edge at the front end of the guide plate 56.
  • the upright legs of the guide plate 56 can be designed to diverge outward in the region of the hopper, in such a way that the guide plate in the region of the rear end of the Filling funnel is essentially flat, so that the conveyor belt can be driven via a cylindrical drive roller.
  • the returning run can be guided by appropriate guide and tension rollers.
  • the guide plate 58 could also be tubular in the area of the filling tube 60, a slot 62 having to be arranged in the upper area. This profile of the support plate 58 could then also be continuously developed into a flat plate towards the rear deflecting end of the conveyor belt.
  • a filling pipe 64 which in cross-section can have, for example, an essentially square cross-section, that is, for example, can have a cross-section according to the embodiments according to FIGS. 6 and 6.
  • a lower conveyor belt runs above the bottom of the filling pipe 64 66 on a guide plate 68.
  • the arrangement corresponds essentially to that of FIG. 1.
  • a drive roller 70 and a deflection roller 72 are provided, which in turn can also serve as a tension roller.
  • An inclined inlet shaft 76 leads from an inlet opening 74 into the filling pipe 64.
  • This inlet shaft is delimited on its rear side by a guide plate 78, over which a conveyor belt 80 with a drive roller 82 and deflection roller 84 is guided. The lower end is provided with the rounded deflection edge 86.
  • the upper side of the inlet shaft 76 is delimited by a guide plate 90, which is of an angular design here and extends with a leg 91 in the region of the top of the filling tube 64 up to its front end.
  • a conveyor belt 88 is guided around the guide plate 90, which is guided in the region of the apex 92 of the guide plate 90 via two deflection rollers 94 and loops around a drive roller 96 in this region.
  • the material is already gripped in the area of the inclined feed shaft 76 by the opposite conveyor belts 80 and 88 and is thus fed to the horizontal section which is delimited in the area of the filling pipe 64 by the conveyor belts 66 and 88.
  • the feed shaft 76 can be designed to converge in the conveying direction, for example. This convergence can be fixed. However, it is also possible, for example, to arrange the conveyor belt 80 in a pivotable manner.
  • a convergence of the conveyor belts within the inlet shaft 76 can alternatively also be achieved in that the two legs 91, 93 of the guide plate 90 are connected to one another in an articulated manner at their apex 92, in which case the leg 93 pointing obliquely upwards can be made pivotable about this joint, so that the feed angle between the conveyor belts in the feed shaft 76 is adjustable.
  • conveyor belts 100, 102 in a filling bunker or intermediate bunker located above the connecting flange 98 on the bunker floor in the direction of the opening 74, which are either horizontal or inclined at an angle to the inlet 74 could be.
  • These counter-rotating conveyor belts ensure uniform discharge from the upstream bunker and prevent this segregation in the case of substances where segregation is to be feared.
  • the two conveyor belts 100 and 102 can simultaneously serve to adjust the inlet cross section.
  • at least one of the conveyor belts can be designed to be adjustable in the longitudinal direction, as indicated by the double arrow on the conveyor belt 102.
  • the conveying of the filling material through the filling pipe in bag filling machines can be optimally adjusted to the respective material using the conveyor belts according to the invention, their arrangement and inclination to one another. In this way it is also possible to bag goods that cannot be filled into bags with the known filling devices.
  • FIG. 10 shows an embodiment with a filling tube 104 directed vertically downwards.
  • two counter-driven conveyor belts 110, 112 are provided, which run on guide plates 114, 116 and are provided with guide rollers and tensioning rollers.
  • the walls delimiting the inlet shaft 118 transversely to the level of the conveyor belts can be designed to be stationary. However, it is also possible to design the inlet shaft with three or four bands and then with a cross section approximately corresponding to the cross sections of FIGS. 4 and 6. In the embodiment according to FIG. 10, the inlet shaft 118 again has a convergence towards the outlet end.
  • conveyor belts conveying in the direction of the inlet opening 106 can be arranged above the connecting flange 108 in the bottom of an intermediate bunker or the like, analogously to the conveyor belts 100 and 102 in FIG. 9.
