Definitions

  • the invention relates to a device for filling and closing sacks or bags according to the preamble of claim 1.
  • Roto-Packers It is also known in so-called Roto-Packers to divide the different operations over several processing stations, with the result that a higher performance of such machines can be achieved.
  • the invention has for its object to design a device of the type presumed to be known in such a way that its filling capacity increases, the changeover from one sack format to another should also be possible at short notice on a small scale.
  • the provision of external grippers which grip the sack in its side folds, allows the opened and filled or partially filled sack to be transported to the next processing station without the sack having to be closed beforehand.
  • the filling process can also be divided up in such a way that the main quantity of the dosing material is filled in and possibly pre-compressed in a first filling station, while the remaining quantity can be precisely metered in in a second filling station.
  • the provision of external grippers, which are moved in the invention with a cyclically reciprocating carriage thus allows the operations otherwise occurring at a processing station to be distributed over a plurality of individual stations arranged one behind the other.
  • the external grippers according to the invention which grip the outer folds of the sack, have the advantage that they enable a substantially better utilization of the filling volume of the sack.
  • such external grippers allow a secure fixation and a safe transport in the defined position desired in each case. This also applies if four external grippers are provided in the three successive processing stations, that is to say in the pre-opening station, in the filling station and in the closing station, which take over the sack one after the other.
  • Various suction elements or suction strips are provided in the construction according to the invention.
  • suction elements or suction strips are used in the pre-opening station to pre-open the sack and ensure that the outer folds of the pre-opened sack can be gripped by external grippers.
  • suction strips may be used to support the holding effect.
  • the drive members for moving the outer grippers and / or the suction strips apart or preferably are preferably arranged at an acute angle that deviates from the horizontal, which is usually 45 °. This acute-angled arrangement allows the system to be adapted very quickly to different sack formats.
  • the external grippers and / or suction strips are not only moved further towards the center due to the inclined arrangement of the drive when the bag format is reduced, but at the same time further downwards, as is necessary when the format is changed.
  • the stops sit on a disc which can be pivoted about an axis. Such an arrangement proves to be particularly robust and reliable. If the stops are formed, for example, by adjustable screws, a fine adjustment can be made to the stops if necessary.
  • the drive of the fixed four external grippers is coupled to the drive for the folding members inserting the side folds.
  • Such a coupling by means of a coupling linkage ensures that the adjustment path of the folding members is also automatically adjusted when the format is changed.
  • a sealing station it proves to be expedient for a sealing station to be followed by a sealing station in which the plastic layer is welded in the region of the fold line if a plastic layer of the paper sack is provided.
  • welding jaws are provided at the welding station for welding the sack in the upper lateral corner areas.
  • the welding of the welding jaws in the upper corner area is completely free of prototypes.
  • a side gusset bag closed in this way assumes a shape which is very close to the ideal shape of the cuboid after the final closing.
  • a first folding station in which a first folding takes place, is followed by a second folding station for a second folding.
  • a machine frame 35 carries a plurality of guide tubes 36 arranged on both sides and distributed over its length, on which the guides of a slide, which is designated by 1, are mounted in a longitudinally displaceable manner.
  • the device shown in FIG. 1 has various stations, namely a pre-opening station 6, the subsequent filling station and then the closing station 7, which can also be designed as a refilling station and closing station. This is followed by a welding station 8, a first folding station 9, a reserve station 11, which is provided for inserting handles, and finally a second folding station 10.
  • the structure of these different stations can be seen better from the individual illustrations:
  • the individual bags arriving in a package are removed from the package by suction devices and moved between suction strips 15.
  • the suction strips 15 are moved apart via the drive cylinders 18 and 19, namely until they abut one of the stops 24 and 25 arranged several times on the two cylindrical disks.
  • These stops 24 and 25 are designed as screws and can because of their Screw character can be finely adjusted by screwing in or out.
  • the desired stop 24 or 25 is brought into position in accordance with the desired sack format.
  • the external grippers are designed as pivotable grippers that work with a corresponding drive, which is not shown in detail.
  • the pre-opened sack 3 is moved by means of the slide 1 into the filling station 4 under the stationary filling funnel 37.
  • the pre-opened sack is then gripped by the stationary, also swiveling grippers 2 connected to the two suction beams, which can be moved against and apart from one another.
  • the carriage 1 can move back to pick up a new sack in the pre-opening station.
  • the grippers 12 attached to the carriage 1 move out of the closing station and into the takeover position shown in FIGS. 6 and 7, in which they grip the filled sack 3 in a clamped manner.
  • the stationary grippers 2 are released and, with the next working stroke, the carriage uses the grippers 12 to convey the filled sack 3 from the filling station to the closing station 7.
  • both externally arranged grippers 14 are provided as well as stationary folding members or folding members 26 and 27.
  • the folding members 26 and 27 are carried along by means of a coupling linkage 38.
  • the folding members 26 and 27 insert the gussets.
  • two clamping strips 39 and 40 clamp the almost completely folded bag.
  • the clamping strips 39 and 40 are fastened to the slide 1 and transport the clamped sack further into the welding station with the next stroke.
  • terminal strips the drive of which is not shown in more detail, are provided for the further transport of the processed sack.
  • the bag is welded along an upper fold line. It is possible that the corner regions 29 and 30 are also welded by appropriate design of the welding jaws.
  • the first folding takes place in the subsequent folding station, which is done in the usual way and cannot be described in detail. Double folding is carried out in the second folding station.
  • Double folding is carried out in the second folding station. This is done with the aid of a folding knife 31 which is movable transversely to the longitudinal movement of the sack and which moves the sack above the clamping strips between the folding jaws 32 and 33 of a folding pliers designated by 34.
  • the sack area gripped in this way is then pressed onto the sack area below by pivoting the entire folding tongs (cf. FIG. 34) by means of the pressure piece 40 shown in FIGS. 21 and 22, which sits on the folding jaw 32. Due to the adhesive previously applied to the corresponding points, the double-folded sack 3 is firmly bonded in the position shown in FIG.
