Self-propelled wrapping machine and wrapping system and method

A system for wrapping, with a film of plastic material, loads that are positioned in a working area, comprising:

• at least one self-propelled wrapping machine that is provided with a self-propelled carriage having at least a directional wheel and a guide means system for directing said carriage, a column fixed to said carriage and slidably supporting an unwinding unit of said film and a control unit for controlling at least said guide system;
• a drone that is remotely controllable and provided with sensor means sensors for capturing images of at least one between surfaces and external edges of said loads;
• and
• a central processing unit for receiving at least one between signals and data related to said images from said sensor means sensors so as to locate and identify said loads, calculating on the basis of said images of at least one between surfaces and external edges respective peripheral outlines of plan maximum overall dimensions of said loads and, on the basis of said peripheral outlines, processing respective wrapping paths to be sent to said control unit of said wrapping machine, said wrapping machine moving around a load for wrapping the load with said film along a respective wrapping path avoiding collisions with said load.

A method for wrapping loads with a film of plastic material and by at least one self-propelled wrapping machine, comprising:

• capturing images of at least one between surfaces and external edges of said loads in a working area by means of a drone that is remotely controllable and provided with sensors;
• locating and identifying said loads in said working area by means of a central processing unit that is arranged for receiving at least one between signals and data related to said images from said sensors of said drone;
• calculating by means of said central processing unit, on the basis of said images of at least one between surfaces and external edges, respective peripheral outlines of maximum overall dimensions of said loads and on the basis of said peripheral outlines processing corresponding wrapping paths around said loads for a self-propelled wrapping machine that is in said working area;
• and
• sending to said self-propelled wrapping machine a wrapping path processed by said central processing unit for a corresponding load to be wrapped.

A method for wrapping a load with a plastic film through a self-propelled wrapping machine, comprising:

• positioning said wrapping machine at said load to be wrapped;
• activating sensors of said wrapping machine for detecting at least one between a surface and an external edge of said load that is closest to said wrapping machine;
• activating and moving said wrapping machine around said load wrapping the load with said film and detecting at least one between surfaces and external edges of said load in their total extension;
• and
• said moving comprises controlling a guide system of said wrapping machine in order to guide the wrapping machine around said load so as to avoid collisions with at least one between said surfaces and said external edges for a plurality of wrapping rounds.
