System and method for optimizing the wrapping of palletized loads with film and wrapping method for a wrapping machine

A method for determining a wrapping configuration of a plastic film that is wrapped around a group of products to form a palletized load intended to be moved or transported along a transport settled path, said method comprising the following steps:

• Step 1, forming a palletized load by grouping and wrapping with the film a determined group of products by using a defined wrapping configuration;
• Step 2, detecting and measuring a set of physical quantities, the physical quantities including at least kinematic-type quantities that comprise one or more of linear displacements, speed and accelerations along at least one axis and angular rotations, speed and accelerations about at least one axis, the kinematic-type quantities acting on the palletized load as a result of at least one of movements and stresses that the palletized load is subjected to when the palletized load is moved along a plurality of different test paths and associating to each of the test paths one respective set of the physical quantities detected and measured;
• Step 3, defining each of the test paths as a composition of a respective sequence of elementary path stretches, the test paths and the elementary path stretches being identified and defined by at least one of a digital mapping or cartography system;
• Step 4, associating to each of the elementary path stretches a respective group of physical quantities detected and measured in the elementary path stretch;
• Step 5, defining from the elementary path stretches of the test paths a set of base elementary path stretches which respective groups of physical quantities are associated to and that are able to form with a suitable composition any path of the palletized load;
• Step 6, obtaining the transport settled path as a suitable composition of base elementary path stretches selected by the set of base elementary paths;
• Step 7, obtaining calculated physical quantities that act on the palletized load along the transport settled path as a composition of groups of physical quantities associated to base elementary path stretches of the suitable composition of base elementary path stretches that compose the transport settled path;
• Step 8, positioning the palletized load on a motion platform adapted to support and move the palletized load and inputting the calculated physical quantities as driving data of the motion platform;
• Step 9, operating the motion platform on the basis of the calculated physical quantities to perform a simulation of at least one of movements and stresses that act on the palletized load moved or transported along the transport settled path;
• Step 10, at an end of the simulation, checking if the palletized load wrapped with the film according to the defined wrapping configuration has remained stable and compact;
• Step 11, modifying the defined wrapping configuration if the palletized load did not remain stable and compact and repeating said steps 8 to 11 of said positioning, said operating, said checking and said modifying until the palletized load is stable and compact;
• and
• Step 12, storing a stability wrapping configuration of the film wrapped around the determined group of products adapted to maintain the palletized load stable and compact when the palletized load is moved or transported along the transport settled path,
• wherein each of the test paths represents motion of the palletized load in three-dimensional space about three orthogonal axes and is stored as an executable program, and
• wherein the digital mapping or cartography system shows test path locations of the palletized load over a time interval.
