Abstract

A method and a machine for forming a box from a blank, in which the blank is removed from a storage magazine by suction, the blank is fed horizontally above a support having an upper edge with a V-shaped cross section and faces that correspond to the main walls and are inclined with respect to the horizontal by a given angle a, such that the central folding line, known as the reference folding line, is next to the edge, the blank is placed on the support, the blank is then pressed against a polygonal mandrel, the upper edge of which coincides with and/or is in line with the upper edge of the support, said mandrel having a shape complementary to that of the box, so as to form a tubular box body at an angle to the horizontal, the bottom of the box is formed by folding and pressing together flaps after application of glue, and the inclined box thus formed is ejected, is positioned upright and then is transferred to a filling station.

Dependent claims

A method for forming a box from a blank comprising a sequence of four main rectangular walls ending in a gluing tab that are linked together by first mutually parallel fold lines or by intermediate walls, including a first center fold line or a first intermediate center wall, two first lateral fold lines or two intermediate lateral walls and a first tab fold line or a lateral end wall, and further including an assembly of lateral flaps linked at one side of said sequence by second fold lines perpendicular to the first fold lines, to form the bottom of the box, the method comprising:

extracting the blank from a storage magazine by suction,
conveying the blank horizontally above a support having an upper edge with a V-shaped or substantially V-shaped cross section and faces corresponding to the main walls that are inclined to the horizontal by a given angle α, such that the first center fold line or the intermediate center wall, referred to as the reference center fold line or the reference intermediate center wall, face said edge,
positioning the blank on the support such that the reference fold line or the reference intermediate wall coincides or substantially coincides with said edge,
applying the blank to a polygonal mandrel, the upper edge of which coincides and/or continues in line with the upper edge of the support, the shape of said mandrel fitting the shape of the box, by applying the walls adjacent to said reference center fold line or to said reference intermediate wall to the opposing upper faces of the mandrel and applying the previously glued end walls and the tab to the opposing lower faces of said mandrel, to form a tubular box body inclined to the horizontal,
forming the bottom of the box by folding and applying the flaps to one another after gluing,
ejecting the inclined box,
setting the box is-set upright and transferring the box to a filling station.

means for extracting the blank from a storage magazine by suction and conveying the blank horizontally above a support, said support having a V-shaped or a substantially V-shaped upper edge and adjacent faces corresponding to the main walls that are inclined from the horizontal, said extraction and conveyance means being arranged such that the first center fold line or the intermediate center wall, referred to as the reference center fold line and the reference intermediate center wall, face said edge:
means for controlling the positioning of the blank on the support such that the reference fold line or the reference intermediate wall coincides or substantially coincides with said edge;
means for forming the box that coincide with or continue the line of the support including a polygonal mandrel shaped to match the shape of the box;
means for gluing the flaps and the gluing tab;
means for applying the walls adjacent to said first reference fold line or to said reference intermediate wall to the opposing upper faces of the mandrel and for applying the previously glued end walls and the tab to the opposing lower faces of said mandrel, to form a tubular box body inclined to the horizontal;
means for pressing the flaps to form the bottom of the box by folding and applying the flaps to one another after gluing;
means for ejecting the inclined box thus formed;
means for setting the box upright and transferring said box to a filling station.
