Self-propelled wrapping machine

1. A self-propelled wrapping machine movable around a load to wrap the load with a film of plastic material, the self-propelled wrapping machine comprising:

a wrapping apparatus which includes a supporting base, a column fixed to said supporting base and an unwinding unit suitable to supply the film unwound from a reel and slidably supported by said column;

an automatic guided vehicle movable and arranged to be reversibly and automatically coupled to said supporting base in an assembled condition of said self-propelled wrapping machine to support and move said wrapping apparatus around the load and enable wrapping of the load with the film.

2. The self-propelled wrapping machine according to claim 1 , wherein said automatic guided vehicle is arranged to automatically uncouple from said supporting base in a disassembled condition of said self-propelled wrapping machine wherein said automatic guided vehicle and said wrapping apparatus are uncoupled and separated.

3. The self-propelled wrapping machine according to claim 1 , wherein said supporting base comprises a seating suitable for housing said automatic guided vehicle in said assembled condition.

4. The self-propelled wrapping machine according to claim 3 , wherein said automatic guided vehicle is configured to be automatically inserted into, or removed from, said seating moving along an operating direction nearly parallel to a supporting plane on which said automatic guided vehicle rests and moves.

5. The self-propelled wrapping machine according to claim 1 , wherein said supporting base comprises a supporting arrangement for abutting a supporting plane on which said automatic guided vehicle rests and moves, and for supporting said wrapping apparatus when said wrapping apparatus is uncoupled and separated from said automatic guided vehicle in a disassembled condition of said self-propelled wrapping machine.

6. The self-propelled wrapping machine according to claim 1 , wherein said automatic guided vehicle comprises a lifting system for lifting said supporting base and said wrapping apparatus from a supporting plane on which said automatic guided vehicle rests and moves, in said assembled condition.

7. The self-propelled wrapping machine according to claim 1 , further comprising connecting assemblies for attaching said wrapping apparatus to said automatic guided vehicle in said assembled condition.

8. The self-propelled wrapping machine according to claim 1 , further comprising an interface system for connecting said wrapping apparatus and said automatic guided vehicle in said assembled condition and for allowing transmission of electrical signals and/or power supply.

9. The self-propelled wrapping machine according to claim 1 , wherein said wrapping apparatus comprises at least one electric accumulator for power supply of said wrapping apparatus.

10. The self-propelled wrapping machine according to claim 1 , wherein said wrapping apparatus comprises a moving system for moving said unwinding unit along said column, said unwinding unit comprising the reel of film and a roller assembly for unwinding and/or pre-stretching the film.

11. The self-propelled wrapping machine according to claim 1 , wherein said wrapping apparatus comprises a first control unit for adjusting at least unwinding of the film around the load and said automatic guided vehicle comprises a second control unit for controlling and guiding said automatic guided vehicle at least around the load along a defined wrapping path.

12. The self-propelled wrapping machine according to claim 11 , wherein said first control unit and said second control unit are connected and communicate with each other via an interface system in order to guide said automatic guided vehicle along the defined wrapping path and to control movement of said unwinding unit along said column and the unwinding of the film around the load so as to achieve a defined wrapping configuration.

13. The self-propelled wrapping machine according to claim 1 , wherein said automatic guided vehicle comprises an automatic navigation system.

14. The self-propelled wrapping machine according to claim 1 , wherein said automatic guided vehicle comprises one of a lowered automatic guided vehicle for towing carriages, or an automatic guided vehicle with lifting forks.

15. A wrapping apparatus comprising a supporting base, a column fixed to said supporting base and a unwinding unit slidably supported by, and movable along, said column and arranged to supply a plastic film to wrap a load, said wrapping apparatus being reversibly and automatically couplable to an automatic guided vehicle in an assembled condition and movable by the automatic guided vehicle so as to make a self-propelled wrapping machine according to claim 1 .
