Definitions

  • the invention relates to a machine for filling bags with a bulk product comprising: a first station comprising filling means for filling a bag and first means of mechanical compaction, said first means of compaction being arranged with respect to said means for filling said product as said sack is filled with bulk product, a second station, following said first station, which comprises first sealing means for sealing the filling mouth of said sack.
  • the invention also relates to a filling process that is performed on the machine according to the invention.
  • Machines for filling bags with bulk products are known, both in pre-formed bag filling machines, and in forming, filling and sealing machines that form their own bag and are known in the art for their English acronym FFS (by form , fill and seal).
  • FFS by form , fill and seal
  • To fill the bags it is usual to take advantage of the effect of gravity, so that the product falls by its own weight centrally inside the bag. When falling into the bag, the product is not completely compacted and therefore occupies a volume greater than optimal. This has the disadvantage that it would require a larger bag than is strictly necessary.
  • compaction means at the stage of filling the bag. The compaction means, either by tapping or by vibration, reduce the volume occupied by the bulk material.
  • the level of compaction required depends on the granulometric characteristics of the product, and its geometry and dimensions.
  • the slope angle of the product is relevant, that is, the angle that forms a bulk product mound (similar to a cone), between the side wall of the mound and the horizontal wall of the base, when the product It stabilizes by itself.
  • a reduced slope angle implies that the product has a favorable compaction capacity, while a large slope angle implies that the compaction capacity is unfavorable. If the product falls free and therefore forms a reduced angle, the bag is better filled. On the contrary, a large slope angle implies a lower filling level.
  • a bulk product is understood as a product whose grain size is equal to or greater than 50 microns and preferably equal to or greater than 100 microns. Bulk products range from coarse powder to granular products.
  • the particles have different shapes, such as spherical ball-like shapes or shapes that, without being strictly spherical, are more or less rounded. Alternatively, the particles may have irregular shapes with sharp edges, such as small cylinders, polyhedra or parallelepipeds.
  • An example, not limiting, of this type of product is plastic pellets. Figures 1 and 2 show examples of the geometry of two types of pellets.
  • a plastic pellet of polyamide, polyethylene or similar is shown, with rounded shapes and approximate dimensions of between 3 and 8 mm.

In parallel, a second bag that can be filled has already been placed in the first station. Finally, after the compaction in the second station, the first bag can be passed to the third station to seal the filling mouth.
  • the slope is disassembled and the top of the bulk product becomes flatter. As a consequence, the filling is improved and the bulk density increases.
  • This combination of two stages of compaction and two stages of sealing provides great flexibility to the machine to pack products of very different granulometric characteristics and increases in a way Notorious the productive capacity of the same.
  • the maximum capacity of a machine with a blow to fill or several blows to compact can drop 30% on a regular basis, more than 50% usually and in extreme cases if an extreme compaction is required approximately 80%.
