Definitions

  • the present invention refers to an energy-saving machine for packaging products with heat-shrinking film.
  • packaging machines of the traditional type are sized and structured so as to be able to wrap products of varying sizes with heat-shrinking film. In such a way the investment costs are cut and with a single machine it is possible to advantageously treat the various products in their different sizes.
  • 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 being able to limit as desired the consumption still with the ability of the machine being unchanged according to the variation of the requirements.
  • Yet another purpose is that of being able to also limit the treatment times both according to the material and according to the size of the product being packaged.
  • FIGS 1-3 show a first embodiment in which a machine according to the present invention is wholly indicated with 10, and in the illustrated example it comprises a structure 11 upon which a reel of heat-shrinking film 14 is lodged.
  • a cover or dome 13 constitutes the upper part of the machine 10 which is arranged on a tank or lower part 12 to define a chamber, wholly indicated with 15 only in figure 2.
  • This chamber which is equipped with a heat source and with a fan for circulating the air which is heated by the aforementioned heat source, defines a single cutting, sealing and heat-shrinking space of the film used.
  • a composite dividing wall is arranged formed from an upper portion 17, integral with the dome 13, and a lower portion 18, inserted into the tank 12.
  • both the dome 13 and the tank 12 define two separate zones A and B which can be used together or separately thanks to an external control (not shown).
  • Each zone A and B then foresees a transportation and support group 22A and 22B for a product schematised at 23.
  • each zone A and B foresees an air circulation fan 20A and 20B and relative heat sources, such as two groups of resistors 21A and 21B.
  • Both the fans 20A, 20B and the groups of resistors 21A, 21B can be selectively activated so that it is possible to only make those of zone A (fan 20A and resistors 21A) function in the presence of small products 23, supplied one after the other only in that zone.
  • Figures 4 and 5 show a second embodiment wherein the dome 13 and the tank 12 are equipped with mobile portions of the dividing wall.
  • the upper portion 17 of the dividing wall be mobile.
  • the use of an upper portion or mobile partition 17 transversally divides the dome.
  • This upper portion or mobile partition 17 can be guided by a group of two guides 24 (only one of which is shown) inside which they are capable of sliding with or without spherical pins 25 bound to the upper portion 17 of the dividing wall.
  • This dividing wall 17, 18 constituting a partition can in this case form a single body with a lower plate 26 carrying the motor of the fan 20, capable of sliding on a base portion 12a of the tank 12.
  • a lower plate 26 is, for example, guided by suitable guides, with or without balls, arranged in the lower part of the body of the machine, in such a way that, moving the dividing wall 17, 18, the fan with the relative motor 20 also moves so that they are always arranged in the closest position to the centre of the area created by the dividing wall and by the rest of the tank 12 and of the dome 13.
  • two distinct groups of fans 20A and 20B can be used connected to two relative groups of resistors 21A and 21B.
  • the second fan 20B shall only be activated when the area of use shall be such as to have to use the air vortex created by this to obtain a better yield.
  • the lower portion 18 supports and/or can support a support grill or transportation and support group 22 of a product schematised at 23, which also adapts to the varying useful size of the operating zone inside the machine.
  • a support grill or transportation and support group 22 of a product schematised at 23, which also adapts to the varying useful size of the operating zone inside the machine.
  • a suitable slit 27 behind which is arranged a support system, such as a roller 28, which also eases its ability to slide when the lower portion 18 of the dividing wall is moved.
  • the activation of these upper 17 and/or lower 18 partition portions therefore determines the activation of the heating resistors 21A and 21B which are of a number and power such as to correspond with the volume requirement of the dome 13 and of the tank 12 determined by the position of the portions of dividing wall 17 and 18.
  • Such resistors which constitute the heating group (heat lung), instead of being in a single body like in traditional machines, is divided into two parts separated longitudinally each containing two, three or more resistors of an appropriate power which in total, however, does not differ much from the maximum used on traditional "dome" machines of an equal maximum format.
  • the group of resistors 21A arranged towards the right shall always be heating up (when the machine is set up for shrinking) whereas the group arranged on the left shall be activated two resistors 21B at a time, when the portions 17, 18 of dividing wall divide the total volume of the machine by about 2/3. On the other hand, when this ratio is exceeded the third resistor 21B is also made to heat up to have an optimal shrinking.
  • Figures 6 and 7 show yet another embodiment of the invention wherein the machine for packaging products with heat-shrinking film foresees an even greater saving of energy.
  • this machine realises both a regulation of the chamber and the operating elements connected to it and a regulation of the support grill or of the transportation and support group of the product or products to be packaged.
  • a dividing wall 17, 18 is foreseen which can be moved according to predetermined discrete positions in the machine in correspondence with arrangements indicated with X, Y, Z, etc.
  • the wall 17, 18, moving in correspondence with the aforementioned arrangements X, Y, Z etc., defines a chamber of a greater size which can adapt to the size of the product to be packaged. Should the height or thickness of such a product be large, it is, moreover, also possible to vary the arrangement of the support grill 22 according to variable height arrangements S, T, V, W, etc.
  • At least one fan 20 and relative resistor groups 21A and 21B are foreseen, capable of being activated through sensors or microswitches 19A, 19B which selectively control the two groups of resistors 21A and 21B arranged in the tank 12.
