System and method for forming a custom-sized package
A method and an apparatus ( 10 ) for realising a box ( 9 ) starting from a cardboard band ( 7 ) for packing a plurality of articles ( 100 ) with the box ( 9 ), wherein the plurality of articles ( 100 ) is contained in a reusable crate ( 1 ), the first internal wall ( 4 ) of which is positioned such as to minimise the volume of the chamber ( 5 ) containing the plurality of articles ( 100 ). The apparatus comprises: detecting means ( 11 ) arranged so as to detect data on the volume occupied by the plurality of articles ( 100 ); cutting means ( 12 ) for cutting a cardboard band ( 7 ) and obtaining a portion of cardboard band ( 8 ) in a flat configuration; a control unit which receives the data from the detecting means ( 11 ) and which commands the cutting means ( 12 ); movement means ( 13 ) for moving the bottom wall ( 2 ) of the crate ( 1 ); positioning means ( 14 ) for reciprocally positioning the portion of cardboard band ( 8 ) and the crate ( 1 ) such that the portion of cardboard band ( 8 ) can receive the plurality of articles ( 100 ); folding means ( 15 ) for folding the portion of cardboard band ( 8 ) in a flat configuration so as to form a box ( 9 ).
1. A method for realizing a box starting from a cardboard band for packaging and for packing a plurality of articles within the box, comprising steps of:
providing a reusable crate comprising an external wall, a chamber, a first internal wall, a bottom wall with a projection, the first internal wall being mobile to vary the volume of the chamber, the bottom wall being constrained to the external wall so as to be slidable along a part of an edge of the external wall so as to be disposable with respect to the external wall in a first closed position, wherein the bottom wall closes the chamber with a bottom-wall portion projecting from the external wall, and in a second open position wherein the bottom wall opens the chamber;
arranging a plurality of articles to be packed in the chamber of the reusable crate with the bottom wall in the first closed position;
moving the first internal wall of the reusable crate such as to minimize the volume of the chamber and, thereafter, detecting volume data on the volume of the articles within the chamber;
cutting a cardboard band for packaging according to the volume data, obtaining a portion of cardboard band in a flat configuration comprising a central region dimensioned to restingly receive the articles contained in the chamber of the reusable crate and a peripheral region surrounding the central region;
reciprocally positioning the portion of cardboard band and the reusable crate such that the central region of the portion of cardboard band is placed below the chamber of the reusable crate and can receive the articles from the chamber of the reusable crate when the bottom wall is moved to the second open position;
gripping the projection of the bottom wall of the reusable crate in the first closed position and moving the bottom wall from the first closed position to the second open position to open the chamber so that the articles can be released from the chamber onto the central region of the portion of the cardboard band;
folding the peripheral region portion of the cardboard band in the flat configuration with respect to the central region around the articles resting on the central region so as to form a box containing the articles,
wherein the folding of the peripheral region of the portion of the cardboard band includes drawing the portion of the cardboard band towards and against two folding elements, each of the two folding elements encountering the peripheral region of the portion of the cardboard band and folding the peripheral region with respect to the central region around the articles resting on the central region so as to form the box,
wherein the drawing of the portion of the cardboard band towards and against the two folding elements includes pushing the articles contained in the chamber against the central region of the cardboard band and thus pushing the portion of the cardboard band along with the articles towards and against the two folding elements and, simultaneously with the pushing, aspirating the central region of the portion of the cardboard band to draw the portion of the cardboard band towards and against the two folding elements.
2. The method of claim 1 , wherein the step of folding the portion of cardboard band in the flat configuration comprises steps of:
arranging an abutting plane inferiorly to the at least two folding elements so as to encounter the central region of the cardboard band;
moving the abutting plane, according to the volume data detected as to the volume of articles, so as to vary a distance between the abutting plane and the at least two folding elements;
the drawing of the portion of the cardboard band in the flat configuration against the at least two folding elements including drawing the portion of the cardboard band in the flat configuration up to contacting the abutting plane with the central region of the portion of the cardboard band.
