The invention concerns a method and a machine for automatic production of inserts made of undulated board sheet, for dividing boxes into sections. The method consists in: forming two opposite stacks of blanks, namely one first stack consisting of first blanks (1) designed to form by folding a first part of cross-bracing insert or a first cross-bracing insert, and a second stack of blanks (2) designed to form a second part of cross-bracing insert or a second cross-bracing insert, gripping on one side the first blank (1), and on the other side the second blank (2); simultaneously moving by a pivoting motion the first blank (1) and the second blank (2) so as to bring them in contact with each other by the edge in a common horizontal plane, then in simultaneously folding down on either side of the central panel, the two sets of flaps to form two half-cross-bracing inserts or two cross-bracing inserts
A method for the automatic manufacture of cross-bracing inserts made of sheets of corrugated cardboard for dividing boxes into sections, characterized in that:
The method as claimed in either one of the preceding claims, characterized in that the two half cross-bracing inserts or the two cross-bracing inserts are formed directly by punching in the corresponding box or boxes at the same time as the gripper means go in search of the next blanks.
The method as claimed in one of the preceding claims, characterized in that, with the first set comprising a rectangular first base flap equipped, on a first end side, with a first end flap provided with two notches which are symmetric with respect to an axis of symmetry of the cross-bracing insert and, on the two sides adjacent to said first end side, with two first lateral flaps, also symmetric with respect to said axis, able to be inserted in part into said notches,
The method as claimed in any one of the preceding claims, characterized in that the second sets of the second blanks are each equipped with a central panel connected to said corresponding second set by a fold line, the second blank being seized by the suction-gripping of the central panel, the latter being positioned vertically and symmetrically between the two sets of flaps in contact or practically in contact with one another.
The method as claimed in any one of the preceding claims, characterized in that the central panel is placed in a vertical position only by rotation of the means for the suction gripping of said central flap.
The method as claimed in any one of the preceding claims, characterized in that the suction gripper means are moved using a cam and pulleys set.
A machine for the automatic manufacture of cross-bracing inserts made of sheets of corrugated cardboard for dividing boxes into sections, characterized in that it comprises:
