Definitions

  • Object of the present invention is a product packaging machine with single-fold heat-shrinkable film.
  • Machines are known that allow packaging various products into a single-fold heat-shrinkable film.
  • single-fold film indicates a film longitudinally folded on itself so as to determine two superimposed edges.
  • Known packaging machines for example, consist of a body into which there is formed a chamber provided with a heat source and with a fan for the circulation of the air heated by such heat source.
  • the chamber is closable through a hinged bell, so as to determine a single space for the cutting, heat-sealing and heat-shrinking of the film.
  • the chamber is provided with a grid for supporting the product during packaging.
  • the product to be packaged is inserted between a work surface (arranged at the side of the grid, outside the bell) and the upper edge of the single-fold film, and it is carried on the grid enclosed between two stripes or edges of film.
  • the bell is lowered, and such lowering concurrently causes the actuation of the cutting/heat-sealing blades, of the heat source resistances, and of the hot air circulation fan.
  • the single-fold film is thus cut and heat-sealed around the product so as to form a closed wrapping, and it is shrunk on it thanks to the circulation of hot air into the chamber and the bell.
  • the bell motion and the belt actuation are automated in an intermittent manner.
  • US-A-3 496 700 discloses a packaging machine of the type comprising a heat-shrinking tunnel and a transport path formed by idle rollers.
  • Purpose of the present invention is that of realising a product packaging machine with single-fold heat-shrinkable film which should allow a higher production efficiency even though without a considerable cost increase.
  • a further purpose of the invention is that of realising a packaging machine which should allow an improved use comfort.
  • machine 10 exhibits a body 11 inside which there is determined a chamber 12, in turn provided with a heat source and with a fan for the circulation of the air heated by said heat source (heat source and fan not shown).
  • blades 13 and 14 respectively longitudinal and transversal, for cutting and heat-sealing the film, and chamber 12 is closable through an overhanging hinged bell 15, so as to determine a single space for the cutting, heat-sealing and heat-shrinking of the film.
  • machine 10 of the invention exhibits a plurality of idle rollers 18, adapted to function as support, transport and discharge surface for products 19 and 20.
  • the idle rollers 18 form a path exhibiting a first plane portion 21, corresponding to the heat-sealing area, and a second inclined portion 22, arranged on a side 23 of machine 10, which can be referred to as plane of product discharge through thrust and gravity.
  • the height of such plate 24 can thus be adjusted at pleasure, within a predetermined interval, so that the same plate 24 may function as support surface for the inclined portion 22 of the idle rollers 18.
  • the height of the idle rollers 18, and in particular of the horizontal portion 21 of the same can be adjusted through a system of uprights or racks 30 and 31, provided with relevant engagement means so as to allow the packaging of products 19 and 20, having a considerable height dimension, such as for example packages of mineral water bottles or other relatively high products.
  • the operating sequence of machine 10 (figures 3-9) is as follows: a product 19 is packaged according to substantially known methods, that is to say, it is inserted between the work surface P and the upper edge of the single-fold film (figures 3, 4).
  • Bell 15 is now manually lowered to the position of figure 6 and such lowering concurrently causes (in a per se known manner) the actuation of the heat-sealing blades 13, 14, and the circulation, through fan, of the air heated by the heat source.
  • the single-fold film is thus cut and heat-sealed around product 19 so as to form a closed wrapping, shrunk on it thanks to the circulation of hot air into chamber 12 and bell 15, which can thus be lifted to the position of figure 7.
  • the already packaged product is manually pushed (laterally) along the sliding direction defined by the idle rollers 18 (figure 9), thus, along a reduced-friction surface and, thanks to the inclined portion of the same rollers it is automatically discharged through gravity from the working area of the packaging machine 10, to be further handled.
  • the described system of rollers 18 can also be applied to automatic packaging machines, not of the bell type but exhibiting a heat-shrinkage tunnel downstream of the heat-sealing and cutting area, thus allowing an easy and automatic access of the products to be packaged in such heat-shrinkage tunnel.
