Definitions

  • the invention relates to movable or self-propelled wrapping machines arranged to wrap a film of extensible plastic material around a load consisting of a product or a plurality of products arranged on a pallet.
  • the self-propelled wrapping machines also called self-propelled wrapping robots, are machines generally used to wrap loads of variable shapes and sizes and in limited productions, typically in environments or rooms where fixed or static wrapping machines cannot be used because of the dimensions and/or available spaces.
  • the loads are generally formed by pallets on which a plurality of products and/or objects, also of different sizes and formats, superimposed in a more or less regular manner, is arranged.
  • the wrapping normally for protective purposes, directly concerns the product which is generally large in size.
  • the self-propelled wrapping machines include a cart or carriage that supports a vertical post along which a film unwinding or dispensing unit, which houses a plastic film reel and is provided with a plurality of rollers for unwinding and pre-stretching the film, is movable with alternating rectilinear motion. More precisely, the unwinding unit is provided with a pair of pre- stretching rollers suitable for unwinding the film from the reel and pre-stretching or extending it by a predefined percentage, and with one or more return rollers to divert the film towards the load.
  • the carriage is generally provided with motorized rear drive wheels and a front guide device which includes one or more steering wheels, operated by a steering.
  • the steering can be operated via a guide bar by an operator to manually drive the machine in a manoeuvring configuration, or by a feeler element capable of following the profile or external shape of the load in an operational working configuration, in which the self-propelled machine turns autonomously and automatically around the load to wrap it with the film.
  • the combination of the alternating linear movement of the unwinding unit along the vertical post and the rotation of the self-propelled machine around the load allows the film to be wrapped around the load so as to form a series of intertwined strips or bands.
  • the plastic film is wrapped to completely wrap the load on all its sides.
  • the feeler element comprises an arm which extends externally and laterally with respect to the carriage and is provided at the end with an idler wheel capable of following the external contour of the load to be wrapped.
  • the feeler element exerts a predefined elastic compression or thrust force on the load, so as to maintain contact with the aforementioned load and allow the machine to move reliably around the load according to a path determined by the contour of the load.
  • Self-propelled wrapping machines which, in place of the feeler element, include sensors e.g. ultrasonic, capable of detecting the external surfaces and edges of the load and processing related signals that allow the control unit of the wrapping machine to calculate a wrapping path around the load to avoid collisions. More precisely, the control unit on the basis of the external surfaces and edges of the load detected by the sensors controls the steering wheels and/or the driving wheels of the carriage so as to steer and guide the latter around the load.

  • WO 99/42367 describes an apparatus for wrapping a load with a wrapping material comprising a load supporting surface for supporting the load during wrapping, a dispenser for dispensing the wrapping material, means for performing the relative rotation between dispenser and load so as to wrap the latter with the wrapping material, gripping means for retaining or releasing an end flap of the wrapping material, and a movable support arm above the load supporting surface for radially moving the gripping means between an external position away from the load and an internal position close to the load.
  • US 5450711 describes a machine for wrapping a load with a film of plastic material comprising means for supporting the load, means for supporting a film reel, first means for rotating the film reel with respect to the load around a first axis of rotation, second means for rotating the film reel with respect to the load around a second axis of rotation and actuating means acting on said first and second rotation means of the film reel to control and coordinate their operation.
