Definitions

  • the invention relates to a method for filling a flexible film container within a relatively rigid carton according to the preamble of claim 1 and also relates to an apparatus for performing this method.
  • the containers have a capacity of 500 l and more, whereby individual containers with a capacity of 500 l or two adjacent containers with a capacity of 250 l each can be filled one after the other on Euro pallets.
  • the film container to be filled with the outer carton and Euro pallet is on a lifting table, which assumes its highest position at the beginning of the filling process.
  • the film container inserted into the box is filled from above by a fixed filling device, the lowering process of the lifting table depending on the filling pressure that occurs when filling the film container via a sensor on the pressure plate and a control unit connected to it, which is connected to a hydraulic cylinder or other suitable Lowering devices for the lifting table acts, is controlled.
  • the outer carton for the film container has a flat bottom, and that the side wall parts of the film container are draped either on the side walls of the carton or on the pressure plate serving as a supporting device for the film container in such a way that during filling undesirable folds and cavities form at these points, which can considerably reduce the filling volume and from which particularly viscous filling material cannot flow out completely again when the container is emptied.
  • the pressure plate resting on the film container during the filling process has a flat underside, which, in conjunction with the flat bottom of the outer carton, means that the film wall of the film container is already on the container bottom and away from it at the beginning of the filling process starting from the container side walls in folds, so that proper filling and emptying of the film container is in question for this reason alone.
  • the invention has for its object to further develop the generic method and an apparatus for performing the method so that on the one hand a correct insertion of the folded around the pressure plate of the filling film container is possible in such a way that the wall of the film container is smooth at the beginning of the filling and comes into contact with the bottom of the outer carton in the middle and, in the course of further filling, starts from the middle of the bottom of the carton to the side walls, smoothly against the bottom of the carton, and then the folded-over side wall parts gradually against the resistance of the pressure plate covering the foil container in the outer carton be released from the pressure plate and gradually lay smoothly on the side walls of the outer carton until the film container is finally completely filled and its inlet connection after closing by a cap again from the pressure plate of the filling device g can be solved.
  • the method according to the invention and the device provided for carrying it out have the advantage that the flat-lying, evacuated film container, which is pre-folded in parallel side folds and transverse end folds, in a simple manner by means of the pressure or support plate connected to the filling device from above into the open outer carton can be lowered at the bottom so that already at the start of filling, the filling material entering the film container expands evenly outwards from the central filler neck to the side walls of the outer carton and gradually builds up a uniform pressure in the preferably wedge-shaped cavity below the pressure plate, which initially only takes effect in the middle part of the printing plate between the inclined edge regions and the side folds of the film container folded there.
  • the film container Since the film container not only lies smoothly on the bottom of the outer carton, but also on the side walls of the box, the film container is completely filled with the intended filling quantities.
  • the filling device with the easily replaceable pressure or support plate designed according to the invention for the film container is comparatively light compared to the prior art and can be handled particularly well, in particular in connection with the counterweight compensation.
  • the telescopic tube arrangement for the suspension of the filling device also contributes to this, since the filling device can adapt itself to any deviations from the normal position when lowering into the outer carton and floating during the filling process, and also particularly easily from the assembly unit for preparation the film container on the pressure plate for the actual filling of the film container can be pivoted back and forth or moved.
  • a large container 1 of, for example, 250 l or 500 l content is shown, which consists of a corrugated cardboard box 2 and a film container 3 arranged therein with a upper filler neck 4 and a lateral outlet nozzle 5.
  • the corrugated cardboard folding box 2 can be delivered to the user in a flat state.
  • the outer carton or the corrugated cardboard folding box 2 has a lower punch opening 6 in one of its side walls, which serves as a push-through opening for the outlet connection 5 of the film container 3.
  • flat support wall parts 13, 14 on the two front sides of the container and a U-shaped prefolded support wall part 15 with a V-shaped inclined container base 16 can be inserted into the outer carton 2, initially as a receptacle for the one lying flat 3, 3A, 3B and FIG. 6 to serve pre-folded film container 3, which is shown in its filled form in the upper part of FIG. 2.
  • the flat, closed and evacuated film container 3 has, as shown in Fig. 3, in its center the upper filler neck 4 and on its container side facing away from the lateral drain or drain pipe 5, which before filling the film container 3 by the punch - Put through opening 6 on the outer carton 2 and is fixed in this opening.
  • the actual filling station 20 consists of at least one side assembly table 21 and a receiving device 22 for Filling container 1 with film container 3 and outer box 2, next to which a stand column 23 is arranged with a horizontal pivotable boom 24, which serves as a suspension device for a filling device 25 with a detachably mounted pressure plate 30, which is provided as a support plate for each pre-folded film container 3 is, as will be described in more detail below.
  • the filling head 26 of the filling device 25 consists of a filling bell 27 with an integrated decapping and filling valve mechanism 28, 29 and the pressure plate 30, which is easily detachably connected to the filling bell 27 and the folded film container 3 serves as a support plate.
  • the pressure plate 30 closes the filling bell 27 at the bottom.
  • the initially flat-lying evacuated, preferably rectangular, film container 3 is in each case on its longitudinal and transverse sides 3a, 3b or 3c, 3d against the protruding in the middle of the container upper filler neck 4 folded over in such a way and fixed with the filler neck 4 on the pressure plate 30 of the filling device 25 such that the two folded longitudinal edges 3a, 3b of the film container 3 extend under the pressure plate 30 and the ends of the transverse sides 3c, 3d of the film container 3 die Overlap printing plate 30 from both ends.
  • the pressure plate 30 has, according to FIGS. 6 to 9, on both sides of an essentially horizontal lower middle part 31 trapezoidal outwardly rising edge regions 32, 33, which the folded or folded longitudinal edges 3a, 3b of the film container 3 in the filling shown in FIG. 9 hold down position between themselves and the wedge-shaped inclined bottom of the outer carton 2, while the middle part 3e of the film container 3 can sag under the filler neck 4 into the wedge-shaped bottom recess of the outer carton 2 (FIG.
  • the pressure plate 30 has a central central opening 35 for the filler neck 4 of the film container 3, in which the filler neck 4 passing through the opening can be fixed by means of a tensioning device 36.
  • This clamping device 36 consists of a two-part or multi-part clamping ring 37, the ring parts of which are held together by an outer retaining ring 38 surrounding them and have a conical centering surface 39 for a central opening 40 on the underside of the filling bell 27, with which the filling bell 27 is placed on the filler neck 4 of the film container 3 and can be placed in a sealed manner on the pressure plate 30 connected to it.
  • the filling bell 27 is firmly connected to the pressure plate 30 for each filling process by means of releasable clamping devices 41, 42.
  • the pressure plate 30 can easily be exchanged for another pressure or support plate 30 with corresponding dimensions.
  • the filling device 25 is connected to a counterweight 46 by a stainless steel chain 45 running over deflection devices 43, 44, such as deflection rollers or the like, or by a traction cable, the mass of which is only slightly smaller than the total mass of the filling device 25 with the film container 3 hanging on the pressure plate 30 is dimensioned such that when the film container 3 is filled, a slight buoyancy is sufficient to allow the pressure plate 30 to float on the top of the film container 3 connected to it in accordance with the increase in the contents in the film container 3 .
  • the filling device 25 is loosely mounted by means of a telescopic tube arrangement 47 serving as a lead-through for the counterweight chain 45 or the pulling rope on a suspension device (bracket 24), which is preferably between a mounting unit 21 for the pressure plate 30 with a film container 3 around it and at least one filling station 20 is horizontally reciprocable or pivotable.
  • a counter switch 48 is assigned to the counterweight compensation, which during the filling process depending on the position of the counterweight 46. When the film container 3 is completely filled, it switches off.
