A machine is used for packing bottles by assembling cardboard boxes starting from an unfolded sheet (2) with adhesive strips, in such a way that in an initial step the bottles (6) to be packed are placed on a central part of the unfolded sheet of the box, a central part that will correspond with the bottom of the box. Once the bottles have been put on this central part of the unfolded sheet (2), in a downward movement, the sheet will encounter a funnel-shaped structure (14), whose mouth and due to the weight of the bottles (6), causes the box (8) to be partially assembled, introducing itself inside this funnel-shaped structure (14), resting at its bottom on a movable platform coupled on longitudinal guides (16). Once the initial and main assembly have been carried out, the total folding of the side walls and then the assembly of the mouth of the box will be carried out in subsequent phases, and finally the assembled box with the bottles inside will be ejected by a pusher (40)

1. A machine for packing bottles in cardboard boxes, said machine comprising:a device for feeding an unfolded sheet of cardboard with adhesive strips thereon; a device for feeding a group of bottles; a descending device that receives and supports said unfolded sheet of cardboard and said group of bottles fed onto a central part or bottom of the cardboard sheet, said descending device comprising a U-shaped horizontal support including a pair of branches, said horizontal support movable vertically by means of a pneumatic cylinder, the side walls of the unassembled box in an unfolded position resting on the branches of said horizontal support; a U-shaped guide located under the horizontal support, wherein when the horizontal support moves downward together with the bottles, the unfolded sheet makes contact with the U-shaped guide and due to the weight of the bottles, the unfolded sheet is partially assembled into a box that remains inside the U-shaped guide; a movable conveyor platform located under the U-shaped guide, wherein the bottom of the partially assembled box sits on the platform after being introduced inside the U-shaped guide; a plurality of longitudinal guides on which the movable platform and partially assembled box are conveyed; a plurality of forming devices positioned adjacent to said U-shaped guide and on both sides of the longitudinal guides for forming at least smaller side walls or front ends of the partially assembled box, when the partially assembled box is inside the U-shaped guide, wherein the forming devices are movable toward one another in a direction transverse to the longitudinal guides; a plurality of collapsible lugs associated with the forming devices for inwardly folding top end laps of a mouth of the partially assembled box, the top end laps originating from the front ends of the unassembled box; an arm mechanism positioned adjacent to the longitudinal guides for collapsing a first larger lap of the mouth of the partially assembled box when the partially assembled box is conveyed on the longitudinal guides by the platform; and a total closing device located at a forward position from the U-shaped guide for completing the assembly of the box by collapsing a second larger lap that abuts against the first larger lap after the partially assembled box has been conveyed out of the U-shaped guide. 2. The machine for packing bottles in cardboard boxes, according to claim 1, further comprising a centering device, said feeding device conveying said group of bottles onto the unfolded sheet with said group of bottles being centered on the central part or bottom of the unfolded sheet by means of said centering device.3. The machine for packing bottles in cardboard boxes, according to claim 2, wherein the centering device comprises a U-shaped support having a cross-member and a pair of branches between which each group of bottles is located.4. The machine for packing bottles in cardboard boxes, according to claim 2, wherein the centering device comprises a conveyor support that conveys each group of bottles to the unfolded sheet.5. The machine for packing bottles in cardboard boxes, according to claim 4, wherein the conveyor support comprises:a top base; a plurality of bottom elements for fastening and anchoring the bottles by their necks during conveyance; and a plurality of side elements for clamping the group of bottles during their conveyance to the unfolded sheet. 6. The machine for packing bottles in cardboard boxes, according to claim 1, further comprising a fixed folded guide that starts the folding of said second larger lap during the advance of the movable conveyor platform along the longitudinal guides when the partially assembled box is conveyed from the area where the U-shaped guide is located toward said forward position along the longitudinal guides where the total closing device is located.7. The machine for packing bottles in cardboard boxes, according to claim 1, wherein the U-shaped guide comprises at least:two horizontal strips facing each other; a plurality of vertical strips connected to the horizontal strips and extended downward; and a plurality of forming elements arranged above the horizontal strips and connected thereto, and wherein said plurality of forming elements include a plurality of central elements that have a slant outward and end elements that help to form corner extensions of the box during introduction thereof into said U-shaped guide, and wherein said forming elements form the mouth of that U-shaped guide. 8. The machine for packing bottles in cardboard boxes, according to claim 1, wherein each one of the forming devices of the side walls of the box comprises a support, and further comprising a movable part hingedly joined to each forming device that carries out the positioning of at least the front ends of the unassembled box.9. The machine for packing bottles in cardboard boxes, according to claim 8, wherein the collapsible lugs are coupled to the movable parts of the forming devices.10. The machine for packing bottles in cardboard boxes, according to claim 1, wherein the arm mechanism comprises:a collapsible longitudinal rod; a front arm integral to the rod for collapsing the first larger lap of the mouth of the box; and an elbowed arm integral to the rod with an inclined end section that maintains the first larger lap folded during conveyance of the box when it is removed from the inside of the U-shaped guide. 11. The machine for packing bottles in cardboard boxes, according to claim 1, wherein the movable platform includes movable end parts for collapsing bottom end laps against the front ends of the unassembled box, when the unassembled box is located inside the U-shaped guide, wherein the end laps originate from the bottom of the unassembled box.12. The machine for packing bottles in cardboard boxes, according to claim 1, wherein the total closing device comprises:a jointed central plate for collapsing the second larger lap of the mouth of the box; and a plurality of end folding elements that in turn articulate with said central plate, and said elements folding tongues connected to the second larger lap which abut against the front ends of the box.
