This is a method and device for making a packaging box from two blanks (2, 3), wherein blanks are taken simultaneously from two adjacent stacks (25, 26) and placed on two parallel tracks (29, 30), the blanks are transferred flat until butted longitudinally to an assembly station, the first blank is glued on its way to the longitudinal abutment position, the first and second blanks are butted laterally into their respective positions to give them an exact lateral reference position, they are grasped, and transferred laterally, and the second blank is placed on the first blank which is thus indexed, escaping the drivers (61) of the first track (29) when the second blank is placed against the fast blank, but clamped by vertical pressure. The second blank is then applied to the first blank to glue them together in their respective defined longitudinal positions, and the resulting set of blanks is then transferred to an erecting station where the box is erected by rolling the blanks around a core.

A method for producing a packaging box with a polygonal section from at least two blanks of sheet cardboard or corrugated cardboard material, namely a first blank (2) forming the bottom of said box, and a second blank (3) comprising at least four panels (4, 5, 6, 7) respectively connected togethe
1. A method for producing a packaging box with a polygonal section from at least two blanks of sheet cardboard or corrugated cardboard material, namely a first blank (2) forming the bottom of said box, and a second blank (3) comprising at least four panels (4, 5, 6, 7) respectively connected together by third parallel fold lines (9), comprising a lower free edge lacking a flap on the side of the bottom, said second blank forming a cover for said box, characterized in that blanks are taken simultaneously from two adjacent magazines (25, 26) and said blanks (2, 3) are placed on two parallel tracks (29, 30), namely a first track (29) for the first blank and a second track (30) for the second blank,said blanks are transferred flat to said tracks by being guided substantially with a lateral clearance between two rails (40, 41; 42, 43) by a stopper-drive system, until they butt longitudinally at an assembly station, in a determined longitudinal position for each of the blanks,said first blank (2) is glued during its transfer to the longitudinal abutment position (34, 35),the first and second blanks are wedged in lateral abutment respectively in order to be given an exact lateral reference position,the second blank (3) is picked up, transferred laterally and placed on the first blank (2) thus indexed, by escaping the stoppers (61) of the first track when the second blank is placed beside the first, while being held by vertical-pressure immobilization,the second blank is then pressed onto the first blank in order to glue them together in their determined respective longitudinal positions,and then the assembly of blanks thus formed is transferred to a forming station (90) where the box is formed by rolling the blanks around a core. 2. The method as claimed in claim 1, characterized in that, in order to escape the stoppers (61) of the first track (29), the first blank (2) is raised above said stoppers. 3. The method as claimed in claim 1, characterized in that, in order to escape the stoppers (61) of the first track, said stoppers are retracted downward. 4. The method as claimed in claim 3, characterized in that, in order to retract the stoppers, the latter are pivoted about a shaft (67) situated above the plane of the first track, which allows a release without catching the cardboard. 5. The method as claimed in claim 1, characterized in that the vertical-pressure immobilization is carried out by means of a stopper (63) beveled toward the blanks which is actuated vertically. 6. The method as claimed in claim 1, characterized in that the second blank (3) is brought onto the first blank by transverse translation, after being picked up by suction cups (51) actuated vertically by linear electric motor cylinders, at a speed of translation of between 4 m/s and 6 m/s. 7. The method as claimed in claim 6, characterized in that the second blank (3) is transferred to the first blank (2) by an assembly of two carriages (52, 53) actuated by a belt-clamping drive system. 8. The method as claimed in claim 1, characterized in that, in order to transfer the set of blanks thus formed to the forming station, said set is lifted in order to bring it into contact with pick-up suction cups (84) of an assembly for transferring the set to the forming station. 9. The method as claimed in claim 1, characterized in that, the first blank (2) comprising a series of at least four main sections (12, 13, 14, 15) terminated by a fastening tab (17), said sections being connected together by first fold lines (16) that are parallel with one another, said series of sections forming the outer walls of the base of the box, comprising on one side an upper free edge (18) lacking flaps and being connected on the other side to a series of flaps by second fold lines (20) perpendicular to said first fold lines, the second blank (3) is placed on the first blank by aligning or by substantially aligning the free edge (11) of said second blank with the second fold lines (20) of the first blank and by superposing the third fold lines (9) relative to the first fold lines (16) of the first blank. 10. The method as claimed in claim 1, characterized in that, the first blank (2) comprising a central panel and four lateral peripheral flaps, one of said flaps, previously covered with adhesive, is placed facing a section of the second blank in order to form, once folded around the core, a tray-shaped bottom. 11. A device (24) for producing a polygonal-section packaging box from at least two blanks (2, 3) made of sheet cardboard or corrugated cardboard material, namely a first blank (2) forming the bottom of said box, and a second blank (3) comprising at least four panels (4, 5, 6, 7) connected together by third parallel fold lines (9), comprising a lower free edge (11) lacking a flap on the side of the bottom, said second blank forming a cover for said box, characterized in that it comprises two adjacent storage magazines (25, 26) respectively of the first and second blanks,means for transferring said blanks to an assembly station comprising:means (27, 28) for picking up the blanks from said magazines,two parallel tracks (29, 30) for transferring flat said blanks to an assembly station (31), namely a first track (29) for the first blank (2) and a second track (30) for the second blank (3), each track comprising a stopper-drive system (32, 33) for the blanks,means for guiding each of said blanks, each comprising two rails (40, 41; 42, 43) for guiding the blanks (2, 3) substantially with a lateral clearance up to the assembly station, andmeans (34, 35) for longitudinal abutment at said assembly station, in a determined longitudinal position for each of the blanks,means (36) for coating the first blank with adhesive during its transfer to its longitudinal position,means (44) for wedging in lateral abutment the first and second blanks in order to give them a respective exact lateral reference position against one of the rails,means (50) for pick-up and lateral transfer by suction cups (51) of the second blank (3) in order to place it on the first blank (2) thus indexed, in their determined respective longitudinal positions,means (60) for escaping from the stoppers of the first track relative to the first blank, when the second blank is placed beside the first, and means for vertical-pressure immobilization of said first blank during the escape,means for pressing (70) the second blank onto the first blank,and means (80) for transferring the set of blanks thus formed to a forming station (90). 12. The device as claimed in claim 11, characterized in that it also comprises said forming station (90) comprising a core (23) and means for rolling the blanks around said core in order to form the box. 13. The device as claimed in claim 11, characterized in that the vertical-pressure immobilization means comprise a stopper (69) beveled toward the blanks which is actuated by a cylinder. 14. The device as claimed in claim 11, characterized in that the means (60) for achieving the escape from the stoppers (61) comprise means for retracting the stoppers downward by pivoting of the latter about a shaft (67) situated above the plane of the first track. 15.
