Definitions

  • the personalizing strip is unwound from a reel disposed with its axis parallel to that of the packaging film reel and located on a slider which is moved manually with a change in the dimensions of the package or according to the various requirements of the user, to change or to keep unchanged the disposition of the personalizing strip on the package.
  • the number 1 indicates the reel of stretchable packaging film, from which the film is unwound by suitable means and is fed to a fixed distributor 2 from which the film is drawn by its end by a clamp 3 which, by its reciprocating horizontal traversing movement indicated by the arrow 103, extends a portion 101 of the said film, with a length proportional to the dimensions of the product, over the product 5 to be packaged.
  • While the product 5 is fed by known means (not illustrated) to an elevator 4, scanning means 6, which are also known, measure the dimensions of the product to permit the aforesaid logical operation of the clamp 3 and other components of the packaging machine.
  • the product 5 is then raised against the portion of film 101, which has preferably been subjected to a stage of transverse pre-stretching, after which the flaps of the said film are folded onto the base of the product, after the film has been detached from the distributor 2, and the packaged product is removed from the packaging station, while the flaps of the package are welded by known means.
  • the personalizing strip 107 made of thermoplastic material, which is superimposed on the film 101 and is also held at its end by the distributor 2, is unwound from the secondary reel 7 which is disposed parallel to the reel 1.
  • the reel 7 may advantageously be provided with parallel side pieces 8 for the lateral containment of the strip, and is mounted on the supporting winder 9 with the interposition of means 10 which ensure a precise degree of friction in the unwinding of the strip which is fed to the packaging station solely by the drawing action of the clamp 3.
  • the winder 9 is fixed on and projects from a slider 11 which has bushes 12 sliding on at least one pair of horizontal fixed guide bars 13 which are parallel to the axes of the reels 1 and 7, have a length proportional to the maximum dimensions of the product 5 which the packaging machine can handle, and are supported at their ends by fixed supports 14.
  • At least one of the said bushes, indicated by 112 consists of a nut, preferably a ball screw nut, which interacts with a corresponding screw 113 driven by a motor 15, for example one of the stepping or other type whose speed of rotation and angular position of the shaft may be controlled electronically, as indicated in Figure 2.
  • the numbers 105 and 205 schematically indicate, solely by way of example, the two limit formats of the product which can be handled by the packaging machine. Independently of the product format, the product is positioned, by known means disposed in the packaging machine, on the elevator 4, with its mid-line always aligned with the median longitudinal axis 16 of the film 101.
  • the device described here ensures that when the slider 11 is in a predetermined position, for example one of alignment between the reel 7 and the said median axis 16, a reference point 17 integral with the said slider 11 interacts with a fixed sensor 18.
  • the device according to the invention is completed by a control logic unit 19 to whose inputs are connected the said sensor 18, the means 6 of measuring the dimensions of the products to be packaged, and a programming and interrogation unit 20, consisting for example of a keyboard and visual display unit. Through a suitable interface, one output of the control logic unit 19 controls the motor 15 for traversing the secondary reel 7.
  • the variables relating to the position of the personalizing strip 107 on the package are supplied to the control unit 19 through the unit 20.
  • the strip 107 may be located on the mid-line of the package, or near one edge of the package, at the required distance, as illustrated for example in Figures 2-3.
  • the unit 19 is provided with a memory with a small buffer accumulator battery, to record the last position of the reel 7. When the packaging machine is activated, the position of the reel 7 will be changed, if necessary, according to the changes of format of the product to be packaged.
  • the control unit 19 automatically activates the motor 15 to provide the said resetting condition.
  • the control unit 19 activates the motor 15 normally to ensure that the personalizing strip 107 is placed in the predetermined position on the package.
  • the moving element which carries the reel 7 will remain halted in the aforesaid resetting position, independently of the changes of format of the product.
  • the control system 19-20 may be independent of that of the packaging machine, or may be integrated into the control system of the said machine, with serial connections and with predetermined communications protocols, the whole being done in a way that will be understood and easily applied by those skilled in the art.
