Definitions

  • This invention relates to the packaging sector and in particular relates to a wrapping machine for collective, group packaging of products stacked on a stand, by wrapping with plastic film.
  • the plastic film for wrapping is supported by a reel sustained by a carriage which is motor-driven and movable in a guide along the vertical upright. While the platform rotates, a strip of film is unwound from the reel and, being simultaneously wound around the stack, creates a spiral due to the composition of the translating motion of the carriage and the rotating motion of the platform.
  • the wrapping of the products is obtained by producing two spirals: one ascending (which is formed for example during the carriage upstroke) and one descending (which is formed for example during the downstroke), as well as covering of the top of the stack by placing a sheet of polyethylene over it which, released after production of the ascending spiral, is then engaged and stabilised by the descending spiral which is superposed on it.
  • sheet extender devices For positioning the polyethylene sheet, sheet extender devices are used which comprise a suitable reel of film and are equipped with mechanical actuators which: unwind the film, move it into position and cut it suitably synchronised with the steps of wrapping of the stack by the wrapping film.
  • Such sheet extender devices usually have their own structure, independent of the structure of the wrapping machine, which in the overall configuration of the machine is located in a position diametrically opposed to that of the upright or uprights of the wrapping machine.
  • a second disadvantage is that of requiring the presence of additional units for positioning at a predetermined height the actuators for unwinding and for depositing the sheet of packaging material on top of the stack.
  • this involves: machine structural complexity, a parallel increase in machine costs; and also a cycle time needed for packaging each stack which is relatively long, since it disadvantageously includes significant unproductive times due to positioning of the sheet extender device at a predetermined height.
  • the aim of this invention is to overcome such disadvantages with a solution whose characteristics in accordance with the above-mentioned aims are clearly described in the claims below.
  • the numeral 1 denotes a wrapping machine, designed for wrapping with plastic film 2 - in the form of collective packaging, which is sealed - a plurality of products arranged in a vertical stack 3 on a stand 4.
  • the machine 1 basically comprises [ Figure 1 ]: a platform labelled 5; a fixed supporting structure labelled 6; and an arm 8 supported by the fixed structure 6.
  • the platform 5 comprises a horizontal table, rotatable round a vertical axis 5a, and driven to rotate by the operation of suitably controlled drive means, labelled 15.
  • the fixed supporting structure 6 preferably comprises a single vertical upright 7, next to the platform 5, which supports the arm 8 horizontally, cantilever-style and above the platform 5.
  • the arm 8 in turn sustains a presser 9 which is freely rotatable round its own vertical axis 9a of rotation, coinciding with the axis 5a of rotation of the platform 5.
  • the presser 9 can also translate longitudinally relative to said axis 9a, when subjected to suitable operating commands, between a first, forward limit operating position [ Figure 4 ], and a fully retracted non-operating position [ Figure 3 ].
  • the stack 3 of products is placed on top of the platform 5 and made to rotate round the vertical axis 5a, whilst the presser 9 is brought into its forward operating position and is placed in contact with the top of the stack 3. Acting on the stack 3, the presser 9 presses the stack into contact with the platform 5, thereby helping to stabilise the products and keep them in a neat condition, preventing the stack 3 from losing its shape during packaging.
  • the machine 1 comprises a carriage 16 supporting a reel 17 of plastic film 2.
  • the carriage 16 is constrained to the upright 7 and is motor-driven in such a way as to translate along the upright 7, in both directions along the vertical axis "Z", whilst the film 2 previously coupled to the stand 4 is unwound by the rotation of the platform 5 and is simultaneously rewound around the stack 3.
  • the machine 1 also comprises a sheet extender device 10 for placing a sheet 18 of plastic film 2 between the top of the stack 3 and the presser 9 for sealed wrapping (for example, sealed against water and/or dust), as explained in more detail below.
  • a sheet extender device 10 for placing a sheet 18 of plastic film 2 between the top of the stack 3 and the presser 9 for sealed wrapping (for example, sealed against water and/or dust), as explained in more detail below.
  • the sheet extender device 10 is structurally integrated in the vertical structure 6 of the machine 1 and is supported, cantilever-style by the structure 6, or projecting horizontally, on one side, from the related upright 7.
  • the sheet extender device 10 and the upright 7, that is to say, the fixed structure 6 which sustains it, are both on the same side relative to the platform 5.
  • the sheet extender device 10 is therefore supported fixed to the horizontal arm 8 and is movable with the latter relative to the upright 7, as well as parallel with itself, in the two directions of the vertical axis "Z".
  • the sheet extender device 10 requires the presence of a second reel 19 of plastic film 2 and of actuator means 11 which move alternately along the arm 8, substantially along the horizontal axis "Y" and by means of suitable supporting and guiding means 12 on the arm 8.
  • the actuators 11 of the sheet extender device 10 moving along the arm 8 and synchronised with the movement of the presser 9 between the forward and retracted positions, unwind a stretch of plastic film 2 from the reel 19, and by pulling it convey it beyond the top of the stack 3.
  • Subsequent activation of cutting means associated with the sheet extender device 10 (being of the conventional type and therefore not illustrated in the drawings), allows cutting of the stretch of film 2 unwound from the reel 19 and allows a sheet 18 to be obtained from it which is released over and covering the top of the stack 3, as schematically illustrated in Figure 6 .
  • Figure 3 shows how starting from an initial condition in which: the stack 3 and the related stand 4 are positioned on the platform 5; and after [ Figure 4 ] the presser 9 has been associated with the stack 3 in the operating position and an edge of film 2 from the reel 17 has been coupled to the stand 4; starting rotation of the platform 5 and the simultaneous upstroke of the carriage 16 along the upright 7, a first, ascending, spiral wrapping band is produced around the stack 3.
