METHOD AND MACHINES FOR TRANSFORMING FLEXIBLE CONTAINERS CONTAINING SOLIDS INTO 3D CONTAINERS, MODELS OF 3D CONTAINERS, AND TWO OCCLUSIVE FLAP SYSTEMS

摘要

The invention relates to a method and machines for transforming sealed flexible initial containers, which have at least two faces and contain fluid (liquid/viscous material and/or air/gas) and solids, into containers having different shapes of three-dimensional geometric bodies and which stand independently. The method comprises the following steps: 1- positioning the initial container vertically so that the solids fall downwards and, preferably, holding and/or blocking same using at least one set of securing jaws (3) and/or at least one set of pushing jaws (21); 2- forming at least one flap of at least one of the peripheral lateral sides of the uppermost part of the container, using at least one set of impact jaws (6); and in turn transforming the initial container into a three-dimensional shape by 3- either folding and adhering at least one of the formed flaps to the rest of the container, or sealing or sealing and cutting same using sealing jaws or sealing and cutting jaws (8), preferably via the line of intersection between the flap and the rest of the container, whereby said container permanently maintains the acquired three-dimensional shape; 4- rotating the container by 180° such that the solids fall downwards, in order to free the uppermost zone (or peripheral lateral sides) of the container from solids; and 5- repeating the steps 1 to 3. The invention also relates to two occlusion systems for slowing down and dosing the liquids of the containers.
