Packaging machine

1. A packaging machine, comprising:

a rest surface ( 2 ) for supporting blanks (B) intended to form a quadrangular packaging (C);

a first store ( 31 ), a second store ( 32 ), a third store ( 33 ) and fourth store ( 34 ), each of said stores being structured for containing a plurality of blanks (B) intended to form the packaging (C);

a first handler ( 41 ) structured so as to pick up the blanks (B) from the first store ( 31 ) and to arrange the blanks (B) from the first store ( 31 ) on the rest surface ( 2 );

a second handler ( 42 ) structured so as to pick up the blanks (B) from the second store ( 32 ) and to arrange the blanks (B) from the second store ( 32 ) on the rest surface ( 2 );

a third handler ( 43 ) structured so as to pick up the blanks (B) from the third store ( 33 ) and to arrange the blanks (B) from the third store ( 33 ) on the rest surface ( 2 ); and

a fourth handler ( 44 ) structured so as to pick up the blanks (B) from the fourth store ( 34 ) and to arrange the blanks (B) from the fourth store ( 34 ) on the rest surface ( 2 ); and

folder means ( 5 ), structured so as to fold the blanks (B) arranged on the rest surface ( 2 ) in such a way as to form the packaging (C).

2. The packaging machine according to claim 1 , wherein the four stores ( 31 , 32 , 33 , 34 ) are arranged along a rectangular perimeter.

3. The packaging machine according to claim 1 , wherein each of said first, second, third and fourth stores ( 31 , 32 , 33 , 34 ) is structured so as to contain at least a blank (B) in a position parallel to a side of an article (A) to be packaged.

4. The packaging machine according to claim 1 , wherein each of said first, second, third and fourth stores ( 31 , 32 , 33 , 34 ) comprises two lateral borders (S 1 , S 2 ) which are structured so as to laterally contain a stack of blanks (B), and a support abutment (S 3 ) for supporting the stack of blanks (B).

5. The packaging machine according to claim 1 , wherein each of said first, second, third and fourth handlers ( 41 , 42 , 43 , 44 ) comprises a pick-up device (M 1 ), which is structured so as to be associated with a blank (B); and a motor device (M 2 ), structured for moving the pick-up device (M 1 ) between a pick-up position, wherein the pick-up device (M 1 ) can be associated with a blank (B) and a release position, in which the pick-up device (M 1 ) can deposit the blank (B) on the rest surface ( 2 ).

6. The packaging machine according to claim 5 , wherein the motor device (M 2 ) is structured for rotating the pick-up device (M 1 ) about a first horizontal axis and/or for translating the pick-up device (M 1 ) along an axis which is perpendicular to the first horizontal axis.

7. The packaging machine according to claim 1 , wherein the folder means ( 5 ) comprise a first cursor ( 51 ) for each blank (B) of the packaging, which first cursor ( 51 ) is provided with an operating end ( 52 ) that is projecting and mobile between an initial position, wherein the operating end ( 52 ) is located below the rest surface ( 2 ) and distanced from an article (A) to be packaged, and a final position, wherein the operating end ( 52 ) is located above the article (A) to be packaged and flanked to the article (A) itself.

8. The packaging machine according to claim 7 , wherein the folder means ( 5 ) comprise a pair of second cursors ( 53 ) for at least a blank (B) of the packaging, which pair of second cursors ( 53 ) is mobile along a horizontal direction between a retracted position, in which the second cursors ( 53 ) are distanced from the blank (B), and an advanced position, in which the second cursors ( 53 ) are in contact with a respective end of the blank (B) and fold said end of the blank (B) about a vertical axis so as to arrange the end of the blank (B) in contact with the article (A) to be packaged.

9. The packaging machine according to claim 1 , comprising a gluing device (G), which is structured in such a way that a quantity of adhesive can be arranged on a surface of each of two blanks (B) arranged opposite one another.
