Definitions

  • the present invention relates to a machine for forming-filling packaging bags, in particular for packaging food articles.
  • the thus made bags in particular, can be processed in several manners, by arranging said bags on supporting elements of carousels comprising chain elements, driven either with a continuous or an intermittent movement, which transport the bags for long linear distances, passing through processing stations, in which there are performed the filling and control operations on the bags; then, the filled bags are conveyed to further carousel assemblies, provided with bell elements, in order to evacuate the filled bags and sealing the thus formed packages.
  • the document DE 1 926 223 discloses a simple carousel assembly boxing machine for processing boxes made of a rigid cardboard material.
  • the aim of the present invention is to overcome the above mentioned problems, by providing a machine for forming-filling bags for packaging products, which, while having a performance analogous to that of conventional packaging machines, has a very reduced size.
  • a main object of the present invention is to provide such a machine which comprises very simple driving mechanisms so as to greatly reduce the wear of the mechanical parts of the machine, thereby also reducing the maintenance requirements.
  • Another object of the present invention is to provide such a machine which is specifically designed for optimizing all of the filling and vacuum sealing operations of the bags and which, in addition, is very safe and reliable in operation.
  • Figure 1 schematically illustrates, by a perspective view, the forming-filling machine according to the present invention.
  • the bag forming-filling machine which has been generally indicated by the reference number 1, comprises: a first section 2 provided with means for forming bags 3, a second section 4 provided, in a known manner, with means for filling-in the formed bags 3 and with means for controlling the performed filling-in operation and, finally, a third section or station 5, provided with means for vacuum sealing the filled-in bags 3.
  • the first section 2 comprises a carousel assembly 6, which can in turn comprise, for example, a chain, meshing with two gear wheels 7a and 7b, having parallel vertical axes, at least one of which is rotatively driven by a controllable electric motor 8.
  • a carousel assembly 6 which can in turn comprise, for example, a chain, meshing with two gear wheels 7a and 7b, having parallel vertical axes, at least one of which is rotatively driven by a controllable electric motor 8.
  • holder or supporting elements 9 Spaced along the chain of the carousel assembly 6, are arranged holder or supporting elements 9, provided for supporting the bags 3.
  • the forming of the bags 3 is performed in a forming station 10, which is arranged above the carousel 6 and substantially comprises a forming mandrel 11, having a vertical axis, on which is wound, in a known manner, a film 12 coming from a roll or coil 13.
  • the two vertical portions of the film 12, wound on the forming mandrel 11, are continuously sealed, so as to provide a continuous tubular body, which is cut in preset length portions and downwardly removed, for example by means of suitable crawlers 14, so as to progressively remove said tubular portions constituting the bags 3, from the forming mandrel 11, and so as to properly locate them on the holders 9 of the carousel assembly 6.
  • sealing means for sealing the bottom end portion of the tubular elements formed on the forming mandrel 11, so as to make, from the mentioned tubular portions, the bags 3 during the advancement thereof on the carousel assembly 6.
  • the second section 4 also comprising a carousel assembly, on which there are arranged holders or supporting elements 15 provided for receiving the bags 3 from the carousel assembly 6 and for conveying said bags to the several processing stations, arranged along the periphery of the carousel assembly of the second section 4.
  • the carousel assembly of the second section 4 has a vertical axis and is rotatively driven, about this axis, by a disc of fifth wheel element 16, which is rigidly affixed to the carousel assembly, and therewith a pinion 17 meshes which is driven by a servomotor 18.
  • filling-in devices 19 for filling the bags 3, as well as weighing devices 20, for controlling the filled-in product weight.
  • the third section 5 which is constructionally and mechanically similar to the second section 4; in particular, the third section 5 is also constituted by a carousel assembly, which is coaxially coupled to a disc or fifth-wheel element 31, meshing with a pinion 32 driven by a servomotor 33.
  • the bell 35 in particular, can be raised so as to allow for the operation of devices 37, of known type, by means of which the bags are sealed, as well as of cutting devices 38, for trimming the top end portion of the sealed bags.
  • a conveyor belt 39 Downstream of the sealing and cutting devices 37 and 38 is arranged a conveyor belt 39, by means of which the packaged bags 3 are removed from the forming-filling machine.
  • the holders 15 provided on the carousel assembly of the second section 4, are provided in a number which is equal to that of the holders 34 arranged on the carousel assembly of the third section 5.
  • the pitch diameters of the carousel assemblies of the sections 4 and 5 supporting the respective holders 15 and 34 are substantially equal to one another, so as to afford the possibility of aligning the holders 15 on the top of the holders 34 during the transfer of the bags from the second to the third sections.
  • the servomotors 18 and 33 can be driven in an independent manner, so as to properly control the rotary movement of the carousel assembly of the second section 4, with respect to the carousel assembly of the third section 5, and so as to provide the possibility of properly programming the advancing movements of the two carousel assemblies, to properly finishing the bags.
  • the operation of the forming-filling machine according to the invention should be self-evident from the above description and illustration: in particular, it should be pointed out that the bags 3, formed in the forming station 10, are conveyed to the holders 9 of the first section 2, where they are closed at the bottom and then conveyed to the holders 15 of the second section 4 which, by rotating about the axis thereof, will progressively bring the bags 3 to the filling-in devices 19, and to the weighing devices 20 for controlling the weight of the product supplied by the devices 19.
  • the filled-in bags are pressed and pre-closed, and then they are conveyed from the holders 15 to the holders 34 of the third section 5, where the filled-in bags 3 are evacuated and sealed, and then the sealed bags being removed by the conveyor belt 39.
  • the sections in which there are performed the filling and vacuum sealing operations on the bags are constituted by carousel assemblies, which are driven by gear wheels, it is possible to reduce to a minimum the maintenance requirements and, moreover, the operating sections must be driven in a more accurate manner.
