More in detail, the present invention relates to a machine configured to bundle pouch wrappings, for example paper pouches, to allow them to be easily transported. In other words, the machine in question is configured to pack stacks of pouch wrappings.
  • the present invention finds advantageous use in the technical field of the production and marketing of packaging machines, and more particularly in the technical field of the production and marketing of substantially automatic machines for packaging together a plurality of products.
  • machines for packaging are known, and in particular machines for packaging pouch wrappings are known.
  • pouch wrapping is to be understood, for the purposes of this privative, as meaning a substantially flexible container shaped like a pouch, for example made of paper or plastic or similar, intended to contain further products, for example foodstuffs or similar.
  • pouch-shaped wrapping made of substantially paper material intended to contain bakery products.
  • pouch wrapping have an opening for the products to be contained and an opposite bottom, realised by fixing, normally by sealing or gluing, two opposing flaps. This fixing of the flaps defines a larger footprint than the footprint of the opening.
  • a further drawback is that the stack of pouch wrappings thus formed is difficult to wrap with the plastic layer, increasing costs and packaging time.
  • An example of a packaging machine known in the relevant technical field is equipped with a conveyor belt to transport the pouch wrappings along a movement direction.
  • the pouch wrappings are loaded onto the machine's conveyor belt in groups comprising a plurality of wrappings stacked vertically all in the same direction.

  • the machine of the known type further comprises a mobile platform placed at the exit section of the conveyor belt and configured to receive the pouch wrappings groups.
  • Said movable platform is vertically movable downwards step-by-step, i.e. as it receives a new group of pouches wrapping to allow the next group to stack on top of the previous one.
  • the pouch wrappings groups stack on top of each other rotated 180° each relative to the next and the previous one.
  • the known type of machine involves packing the stack of pouch wrappings groups inside a package, e.g. a cardboard box or a layer of flexible plastic material.
  • a package e.g. a cardboard box or a layer of flexible plastic material.
  • the main drawback lies is that it is very complex to set up a conveyor belt.
  • a further drawback is that the known machine is very expensive to manufacture, which results into a high selling price.
