Abstract
The invention refers to an automatic apparatus for producing nearly parallelepipedal containers of flexible packaging material, particularly suitable for packaging liquids.
Claims11
An apparatus for producing nearly parallelepipedal packaging containers, from a continuous hose of flexible packaging material, comprising two substantially equal and symmetrically opposed assemblies of jaws, mounted to engage between them a length of said hose and to maintain a purely translational continuous motion, said apparatus comprising:
- actuating and guiding means for said jaws, including for each assembly two rotating parallel disks having axes of rotation and transversely distanced fixed bearings mounting said disks for rotation about their axes, each jaw being pivoted on said disks at two points of the jaw which are at the same transverse distance as the rotating disks, to provide for each jaw a kinematic motion like that of an articulated parallelogram;
- said jaw having a portion forming a support, sealing means supported by each jaw, comprising a sealing member adapted to reciprocate with respect to said jaw portion forming a support;
- metering and shaping means supported by each jaw, comprising fixed plate means, pivoting square means and surfaces of said sealing means, said metering and shaping means only defining portions of only two sides of the container to be formed;
- and severing means, supported by each jaw, comprising blade means adapted to slide through said sealing means.
In apparatus for producing nearly parallelepipedal packaging containers from a continuous hose of flexible packaging material, said apparatus being of the type having at least one pair of substantially equal symmetrically opposed jaws which engage between them a length of hose in a manner to effect formation of a parallelepipedal package containing a product, the improved construction for actuating and guiding each jaw comprising two rotatable members disposed in spaced-apart parallel planes;
- means mounting said members for rotation in said parallel planes about spaced-apart axes which extend at right angles to said planes;
- and means pivotally mounting the respective jaw to each rotatable member for rotation about two separate pivot axes parallel to the rotation axes of said rotatable members, the pivot axes of said jaw being spaced apart by a distance equal to the spacing between said rotation axes of said members, whereby upon rotation of said rotatable members the respective jaw shows a kinematic motion like that of an articulated parallelogram.
