Definitions

  • the invention relates to machines for wrapping products with a film of extendible plastics.
  • the invention refers to a wrapping machine arranged for wrapping a film around elongated products that rest on a small number of rests of limited dimensions, for examples products of irregular shape or of curve shape supported at opposite ends by respective supports.
  • Wrapping machines are known that are provided with a vertical ring that is rotatable around a horizontal rotation axis and supporting a reel of extendible plastics film and a corresponding unwrapping group.
  • Such machines include a horizontal conveying plane that extends through the vertical ring and on which are moved, along a supplying direction parallel to the aforesaid rotation axis, products or groups of products that have to be wrapped with the film.
  • the film of plastics is unwound from the reel by the unwrapping group and is wound around the product so as to form a series of plaited bands or strips, owing to the combination of rotation movements of the vertical ring, that supports the reel of film, and linear movement of the product in the supplying direction.
  • Some machines are further set up for laying on the product or on the group of products a covering sheet on which the film of extendible plastics is subsequently wrapped.
  • the covering sheet which is also made of plastics, separates and insulates more effectively the product from the external environment.
  • the conveying plane generally consists of two conveyors, for example two conveyor belts or mats, that are aligned with one another and separated by a gap or an interruption at the vertical ring to enable the film to be wrapped around the objects.
  • the width of the gap i.e. the distance between the conveyor upstream and the conveyor downstream, depends on the width of the reel of film.
  • Such wrapping machines have the drawback of being able to wrap with film of plastics only elongated products that are able to exceed the aforesaid separation gap between the two conveyors, i.e. products that rest for almost the entire extend on the conveyors and that at the same time have a length that is greater than the width of the gap.
  • Products having a length that is the equivalent to that of the width of the gap and/or products that rest on a small number of rests of limited dimensions, for example products of an irregular shape or of curve shape arranged at opposite ends on respective supports, are not in fact able to get over the gap and move from the conveyor upstream to the conveyor downstream and vice versa.
  • United States patent US 4524568 illustrates a wrapping machine with a vertical rotating ring comprising an inlet conveyor, a wrapping conveying group, a distributing mechanism of the film of plastics supported by the rotating ring and an outlet conveyor.
  • the wrapping conveying group is interposed between the supplying conveyor and the outlet conveyor, at the distributing mechanism of the film, and comprises an upper conveyor and a lower conveyor that are superimposed on one another.
  • the upper conveyor supports and moves the load to be wrapped, whilst the lower conveyor receives and moves the film being wrapped.
  • the film can be wrapped continuously around the load that moves from the supplying conveyor to the outlet conveyor through the rotating ring.
  • the portion of film supported and moved by the lower conveyor disengages from the latter and adheres elastically to the lower portion of the load, previously abutting on the upper conveyor.
  • the film detaches from the lower conveyor and adheres to the load, passing through a suitable passage between the conveying group and the outlet conveyor.
  • This wrapping machine is not, however, able to wrap appropriately curved products, i.e. products have an arched shaped with the convex part facing upwards.
  • the conveying group in fact prevents the film being wrapped effectively around the lower portions of the product that are more distant from the aforesaid conveying group. In this case, in fact, owing to the distance, the only elasticity of the plastics does not enable the film, which disengages from the lower conveyor, to adhere firmly to the lower portion of the product.
  • An object of the present invention is to improve the machines for wrapping products with a film of extendible plastics. Another object is to make a machine that enables products to be wrapped with a film of extendible plastics continuously and completely that rest on a small number of rests of limited dimensions, in particular products with an irregular and/or curved shape arranged on opposite ends on respective supports.
  • a further object is to obtain a machine for wrapping with a film of extendible plastics, and possibly with a covering sheet, products having an arched shape so as to ensure an adhering and stable wrapping.
  • a wrapping machine comprising a wrapping unit for wrapping with a film a product, in particular a curved elongated product, first conveying means and second conveying means placed respectively upstream and downstream of said wrapping unit for moving said product along a supplying direction, and transferring means interposed between said conveying means for moving said product through said wrapping unit, characterised in that said transferring unit comprises transferring means that is movable at least between a retracted position, in which it does not interact with said film wrapped on said product, and an extended position, in which said transferring means supports and moves said product through said wrapping unit.
  • the transferring means in the extended position enables the supports, or rests, of the product to pass between the first conveying means and the second conveying means through the wrapping unit without the need to interrupt wrapping.
  • the product is slidably supported by first movement means, fixed to a supporting frame of the transferring unit, and by second movement means, fixed to a carriage of the transferring means that is slidably mounted on the supporting frame.
  • the transferring means comprises abutting means that is movable between an abutting position, in which it protrudes from the carriage to engage the moving product, and a disengaging position, in which said abutting means is inside the carriage so as not to interact with the product.
  • the product when engaged by the abutting means pushes the transferring means into the extended position.
  • the transferring means further comprises slides around which the film wraps when the transferring means moves the product through the wrapping unit.
  • the slides enable the film to disengage easily from the transferring means and to adhere to the product when the aforesaid transferring means is returned to the retracted position and/or when the product is advanced with respect thereto.
  • the transferring means does not interfere with wrapping of the film around the product.
  • This enables, in the case of curved products, in particular products having an arched shape with the convex part facing upwards, the film to be wrapped effectively also around the lower portions of the product, said lower portions being further from the conveying means, so as to obtain compact and uniform wrapping along the entire length of the product.
  • the product can be moved along the supplying direction and the film can be wrapped at high speed.
  • the wrapping machine 1 of the invention arranged for wrapping a product 100 with a film 50 of extendible plastics unwound from a reel 20.
  • the product 100 in particular with an elongated and curved shape with the convex part facing upwards, rests on opposite ends 100a, 100b, on respective supports 101, 102.
  • a front end 100a rests on one or more front supports 101
  • a back end 100b rests on one or more back supports 102.
  • the product can rest directly on the ends 100a, 100b.
  • the product 100 can include a single curved element or a plurality of curved elements that are superimposed and/or placed side by side to be packaged together.
  • the machine 1 comprises a wrapping unit 2 arranged for unwrapping the film 50 from the reel 20 and wrapping the film 50 in strips or bands superimposed on the product 100.

  • the ring 21 supports the reel 20 and a group of unwrapping and tensioning rollers 23 of the film 50.

  • first conveying belt 12 and the second conveying belt 13 can be motorized and driven by a respective electric motor.
  • the transferring means 7 also comprises abutting means 14 arranged for abutting on the product 100 during movement thereof in the advancing orientation K such that the same product 100 pushes the transferring means 7 from the retracted position A to the extended position B, as explained further on in the description.
