Definitions

  • the material falls under gravity from an hermetically sealed degassing and weighing chamber mounted above the filling chamber, passing through a tube into the bag.
  • the neck of the filled bag is heat-sealed under vacuum in the filling chamber by two sealing heads.
  • the sealed, filled bag is then removed from the filling chamber by opening the door and the bag is removed from the enclosure by a suction plate which grips one side of the bag.
  • the bag can be inflated before insertion into the enclosure in order to produce its maximum volume.
  • PACKAGING MACHINE BACKGROUND OF THE INVENTION This invention relates to packaging materials of low mesh size in bags of flexible material. It relates to a machine for such packaging.
  • Pulverulent or granulated products such as cements, lime, sugar, flour and granulated plastics material are normally packaged either in paper, plastics or plasticized jute bags etc. in the case of small amounts (less than lOkg.), or in vessels made of metal, reinforced plastics or reinforced concrete, such as containers or silos, in the case of greater amounts.
  • these finely divided products takes place either in bags for small amounts or finely divided amounts or in vessels made of metal or possibly reinforced plastics for larger amounts. In the latter case, whether they are conveyed by road, rail, waterway or sea, the vessels are generally permanently mounted on specialized transportation appliances.
  • the time required for creating the vacuum does not make it possible to envisage an economical industrial exploitation.
  • the dura tion of the operation depends on the volume to be packaged and on the pressure drop undergone by the evacuated air, this pressure drop being particularly dependent on the dimensions of the inter-granular spaces. In the case of a material having a low mesh size, these dimensions are very reduced and even tend to decrease as the value of the vacuum increases, under the action of atmospheric pressure exerted on the walls of the enclosure.
  • the new machine comprises:
  • At least one door for opening the second chamber, allowing introduction of the bag therein and to bring the neck of the latter under the discharge pipe;
  • each bag is inflated before filling to produce its maximum internal volume.
  • Packaging may also take place with a controlled gaseous atmosphere.
  • the packaging time itself is shorter, since the volume of gas to be eliminated is less.
  • the volume of material does not vary during its packaging and it is possible to give the packaging enclosure a well defined shape before filling, so that it has at least one flat face for gripping by the nozzle. For the same reason, it is thus possible to use containers which are lessflexible, thus thicker and stronger than the sheet of plastics material used in the known methods.

When they are full, they preferably generally cubic shape, as shown, and have at least one flat side enabling them to be gripped by a suction plate.

  • each bag is engaged manually on the lower end portion 8 of a vertical tube 7 at the upper end of which a blower 9 blows in air.
  • a microswitch (not shown) causes inflation of an annular seal 10 placed around and secured to the tube 7, at its lower end 8 (see FIG. 2).

  • FIGS. 3 and 4 show that the end closure door 20 is provided with a device intended to retain the neck of the bag while the bag is filled. In fact, this operation cannot be carried out by the telescopic tube 7, which must be extracted from the neck of the bag before closing the door 20 and after the seal 10 has been deflated.
  • the neck-retaining device comprises two arcuate members 30 and 31 which, when they are in position, form a horizontal circular ring fitted on the upper edge 6 of the neck of the bag.
