Definitions

  • the present invention refers to a machine with a dome for packaging products in centre-folded heat-shrinking film.
  • Packaging machines formed from a structure, upon which a mobile dome is hinged, which closes the top of a heat-shrinking chamber, containing a fan for circulating the air and heating means, are known.
  • the dome is integrated with a cutting and sealing frame, equipped with sealing rods and facing a counterframe, mounted upon the structure.
  • the chamber is moreover equipped with a support surface of the product in the packaging step.
  • the product partially wrapped in the centre-folded film, in other words placed between two flaps of a film folded longitudinally upon itself, is arranged inside the chamber.
  • the dome is lowered so as to activate the sealing blades which close the open sides of the film.
  • the heated air is made to circulate which causes the shrinking of the film on the product.
  • the operator lifts the dome to remove the product from the support surface.
  • Machines with a dome of the known type are mainly used with transparent PVC film, which is easy to seal and to shrink, and does not hold heat. Therefore, the removal of the packaged product from the machine with a dome can be carried out manually by the operator even immediately after the sealing operation. Nevertheless, PVC film has a high cost of purchase, which makes the use of polythene as an alternative, which is substantially more cost-effective, desirable.
  • polythene has the drawback of being more difficult to seal. Indeed, as the dome is lowered the material tends to remain stuck to the sealing rods.
  • the general purpose of the present invention is that of overcoming the aforementioned drawbacks of the prior art in an extremely simple, cost-effective and particularly functional manner.
  • Another purpose is that of realising a packaging machine which allows greater efficiency in production.
  • a machine with a dome for packaging products in centre-folded heat-shrinking film in object is wholly indicated with 10. Only the most useful functional elements for understanding the present invention shall be shown of the structure of the machine, which is per se known and to which a reel of heat-shrinking film 11 is applied.
  • the machine with a dome 10 comprises a body 12 upon which a mobile dome 13 is hinged which, in lowered position, defines a heat-shrinking chamber 14, equipped with a heat source 15, for example made up of many resistors, and with a fan 16 for forcefully circulating air, schematised in the figures.
  • the dome 13 carries along the edges a sealing frame 17, equipped with sealing rods 18 and facing a counterframe 19, mounted on the body 12.
  • the heat-shrinking chamber 14 is, moreover, equipped with a transportation and support surface 20 for a product 21 being treated, or with another equivalent means.
  • the transportation surface 20 consists of a motorised conveyor belt made out of a suitable heat-resistant material of the high-friction type, but it can be replaced by equivalent techniques, for example by motorised rollers.
  • the motorisation, as well as the command device for the transportation surface 20, are not described since they are well known to the man skilled in the art.
  • the packaging machine 10, object of the present invention is equipped with a cooling device 22, applied to the body 12 at the exit of the dome 13 and arranged bridging over the transportation surface 20.
  • the machine with a dome 10, object of the present invention has specific innovative characteristics for feeding with the reel of heat-shrinking film 11 made out of polythene, without however prejudicing the possibility of using films made of PVC or other.
  • the operating sequence of the machine is the following: the product 21 is packaged according to substantially known methods, in other words inserted between the flaps of the centre-folded heat-shrinking film.
  • the dome 13 is lowered causing the sealing of the film between the sealing rods 18, of the frame 17 and of the counterframe 19, respectively (figures 2 and 5).
  • the moving of the dome 13 is carried out manually by the operator.
  • the salient characteristics of the machine with a dome 10, object of the present invention can also be transferred to a machine with automated operation.
  • the product 21 is made to advance integral with the transportation surface 20 - whether a conveyor belt or another equivalent means of the high-friction type - by a short distance, so as to cause the detachment by yanking of the film held under the sealing rods 18 (figure 3).
  • This teaching is indispensable for the use of polythene film which, due to its physical properties, tends to remain applied to the sealing rods 18.
  • the dome is opened (figure 4) and the packaged product 21 is removed onto the transportation surface 20.
  • the product 21 is conveyed below the bridging cooling device 22, where it is hit by a mass of cold air.
  • packaged products 21 which are cooled and therefore which can safely be moved by the operator are gathered on the discharge line 23.
  • the shapes of the machine with a dome of the invention can be different to those shown just as a non-limiting example in the drawings, just as the materials can be different.
