Abstract:
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.
