Definitions

  • the invention relates to a device for forming, filling and closing sacks according to the preamble of claim 1 and to a method according to the preamble of claim 12.
  • a device is for example from the German patent application DE 10 2005 037 916 A1 out.
  • This device is usually a film tube, often a film tube with gussets, fed, which is withdrawn from a hose reel.
  • a cross-cutting device a piece of hose is separated from this hose, wherein the newly emerging, leading-running hose end is provided, for example in a welding device with a transverse weld, which forms the bottom of the subsequent bag.
  • the empty bag is transferred from a gripping device to another gripping device.
  • the empty bag can be taken over by further gripping means (hereinafter referred to as "second gripping means") which fix the bag during the filling process.
  • second gripping means In the filling station opening means are generally provided which engage the two walls of the empty bag to pull them apart. This are in known devices of this kind mostly sucker, which sit on the outer walls and suck them. Then the suckers can be moved away from each other. In this way, a filling opening on the empty bag, so that it can be filled.
  • For filling usually serves a filler neck, through which the contents is passed into the bag.
  • the DE 10 2004 037 916 it is intended to lift the opened bag so that the filler neck reaches into the bag interior.
  • the bag is lowered. In this way, the drop height of the filling material between the lower outlet opening of the filler neck and the surface of the already filled filling material is minimized.
  • the bag is now taken over by further gripping means and conveyed to a closing device, where the bag is closed. This is usually done by attaching another transverse weld, the so-called head weld.
  • This so-finished, filled bag can now be removed, with several such bags are usually initially stacked on pallets.
  • the generic EP 0 844 175 A proposes a device in which the opening means during the transport of the bag to the filling station a highest position occupy, which lies above a plane which is spanned by the upper edge of the empty bag when the empty bag has reached its highest position in the area of the filling station.
  • the second gripping means are arranged laterally of the empty bag.
  • the object of the present invention is therefore to propose a further device and a further method in which the sack, which is supplied as empty sack to the filling station, can be gripped securely by the second gripping means, which fix the sack during the filling process.
  • the second gripping means are movable into a position which lies above the plane which is spanned by the upper edge of the empty bag, when the empty bag has taken its highest position in the region of the filling station.
  • the second gripping means are designed such that they can be moved to a position so that they lie completely above said horizontal plane.
  • the gripping means and the opening means can be pivotable about horizontal axes.
  • the opening means may also be arranged on lever gears which move the opening means on a path which lies within the circular path which would describe the opening means, if they were swung by means of a rigid lever arm.
  • sealing element which is applied to the insides of the walls of the empty bag.
  • a sealing element generally has a central opening through which the filling material can be filled into the interior of the bag. Through this opening and the filler neck can be inserted into the bag interior, in which case the sealing element serves to seal the gap between the, usually cylindrical, outer wall of the filler neck and the inner walls of the empty bag.
  • the sealing element is movable into a position above the horizontal plane already described.
  • clamping elements can be provided which press the bag walls from the outside onto the sealing element, so that it is effectively avoided that leaks occur between the sealing element and the bag walls, which may for example stem from the elasticity of the bag material.
  • these clamping elements are movable into a position which lies above the plane passing through the upper edge of the bag is clamped when it has reached its highest position in the filling station.
  • the device according to the invention comprises a first support device, which serves to move the bags vertically, so that they can be pulled over the filler neck.
  • this carrying device Up to the time at which a blank bag was completely taken over by the second gripping means, there is advantageously this carrying device, on which the elements described above can be arranged, but at rest.
  • the mass to be moved would be large.
  • the transfer time would be excessively extended by the second gripping means until the bag was gripped, which would considerably reduce the efficiency of a sack forming, filling and closing apparatus.
  • it is therefore provided to keep the delivery between the delivery of a filled bag and the acquisition of a new empty bag at rest, so not to move the support device. In this way, the performance of the entire device can be maximized.
  • the first support means which is also referred to below as the support element, only support the opening means, which are no longer in contact with the bag at the latest when the filling process is started, since the bag then the sealing element is kept open.
  • All other elements which are in connection with the bag during filling ie the second gripping means, the sealing element and the clamping elements, are advantageously carried by a holding plate, which in turn is supported on the first supporting plate.
  • the holding plate is supported by load cells. To this Way, a weighing of the bag is made possible during filling, so that the most uniform possible filling of all bags can be ensured. Under load cells are all means to understand with which a weighing is possible, such as spring elements.
  • Fig. 1 shows a filling station 1 in a device for forming, filling and closing of bags.
  • This filling station 1 comprises a support element 3 which is arranged on a component 2 of the machine frame and can be displaced vertically with respect thereto. The direction of displacement is indicated by the arrows X.
  • the support element 3 is located in the FIG. 1 in a starting position in which a blank bag 4 can be taken over.
  • This empty bag 4 is fed by means of a pair of gripper tongs 5 of the filling station, wherein the feed movement comprises a horizontal component, which is represented by arrow Z.
  • the bag 4 has already reached the transfer position, in which it can be taken over by second grippers, which will be described below.
  • the suction cups 8, the second grippers 10, the sealing element 11 and the clamping elements 12 are located until the empty bag 4 has reached the transfer position shown, in a position above the level 7, so that the empty bag on an optimal, time-saving way the filling station 1 can be supplied.
  • the second grippers 10 are arranged on a holding plate 13, wherein the grippers 10 about axes 14 which are arranged horizontally, are pivotable.
  • the sealing element 11 is vertically displaceable by means of lifting cylinder 15, which may be designed as a compressed air cylinder, the lifting cylinder 15 on a manner not shown in detail on the holding plate 13 are attached.
  • the clamping elements 12 are mounted on the support plate 13. The type of storage will be discussed later.
  • the retaining plate 13 is fastened to the support element 3 via retaining elements 16.
  • These holding elements can also be designed as weighing elements, which enables a weighing of the bag and the already filled filling material during the filling process.
  • the empty bag 4 has already been gripped by the second grippers 10, which hold the empty bag relative to the support elements 3.
  • the opening means designed as suckers 8 have already been applied to the outer bag walls. While the grippers 10 engage in the region of the outer edges of the empty bag 4, the suckers 8 come centrally to the walls and are therefore in the view of FIG. 2 hidden by the grippers 10. Now the suckers 8 can be moved apart in the direction z. At the same time, the grippers 10 are moved in the direction Y (this direction is directed orthogonally to the plane of the page), so that the empty bag 4 opens.
  • the support member 3 can be moved vertically upwards to thread the filler neck, not shown in the empty bag 4.
  • clamping elements 12 and the sealing element 11 can likewise be removed again, to such an extent that they again assume their basic positions above the plane 7.
  • FIG. 4 shows again the same view as the FIGS. 1 to 3 ,
  • the arrows B indicate the movements that make up the individual elements perform to occupy the positions above level 7.
  • the indices at the respective letter B indicate which element is moved along the relevant path.
  • the suckers 8 may be mounted on the support plate 3 via a not further illustrated lever mechanism.
  • a lever mechanism can be designed as a four-bar linkage. This consists of two hinged to the support plate levers whose other ends are connected to each other with a coupling. At the coupling itself, a sucker can then be arranged.
  • the trajectory of the teat can be determined, which then from a simple circular path, which would describe a nipple, when he s.einer simple, joint-mounted lever arranged, could differ significantly. In this way, in the case of the present invention, it can be achieved that the pivoting range of the suckers 8 remains limited in the vertical direction. Thus, the task of reducing the overall height of the device can be solved.
  • the clamping elements 12 can be moved by means of such lever mechanism. It is particularly advantageous if both suckers 8 and clamping elements by means of lever mechanism are movable and the movement curve of the clamping elements 12 between the clamping position, as in FIG. 3 is shown, and the position above the level 7 is completely within the movement path of the suckers 8, as is apparent from the FIG. 4 becomes clear. In this way, clamping elements 12 and suction can be moved independently, without causing collisions.
