Abstract

Winder device (1 ) for packing loads (C) by means of a film of plastic material (F) comprising: - a load-bearing column (3) constrained at one end thereof to a rest baseplate (5) or to a self-propelled machine body configured to advance in a plane, along which load-bearing column (3) a slide (6) provided with at least one reel-holder roller (2) of film (F) in plastic material is constrained to slide, - a platform (7) associated with said slide (6) through a support arm (8) and movable by rotation around a vertical axis (Y), parallel to said column (3), said platform (7) being configured to receive a load (C) by resting and make it rotate around said vertical axis (Y), the rotation of the platform (7), together with the unwinding of the plastic film (F) being adapted to coat the load (C) with said plastic film (F).

Abstract

A winding device for loads includes a reel-holder roll adapted for receiving a reel of an extensible plastic film; a vertical column, along which the reel-holder roll is movable; and a lifting plane adapted to receive a load movable along the column, so that the winding device can be used as both a winder and a lifter for forming the load.

Abstract

A method for effecting the wrapping of stacks, which comprises the following phases: preparing a self- propelled winding machine comprising: a self-propelled motorized trolley, suitable for moving on the ground by means of at least two driving wheels whose rotation creates the movement trajectory of the machine, a control unit of the movement of the driving wheels and means suitable for supplying a wrapping material of the stack supported by the trolley, a distance detector assembled on the machine suitable for perceiving the distance from the stack. The method comprises the following phases: arranging the stack in a fixed position with respect to the ground where the machine moves, effecting the wrapping of the stack by releasing the wrapping material while the machine completes a series of revolutionary movements around the stack. The method comprises the following additional phases: establishing a main circular trajectory for the machine, having a constant diameter which is greater than the maximum dimension, in plan view, of the stack, so that the machine always moves at a distance from the stack, initially positioning the machine so that the centre of the main trajectory is conveniently close to the central and vertical geometrical axis of the stack; sending a correction signal to the control unit when the distance revealed by the distance detector falls below a predetermined threshold distance, establishing a corrective trajectory for the machine wherein the radius of the main trajectory is varied following the emission of said correction signal, said corrective trajectory being such as to move the centre of the movement trajectory of the machine towards the axis of the stack, and re-establishing said main trajectory for the machine.
