Definitions

  • the invention described in US 7,316,102 involves an apparatus for extracting air from within flexible packages.
  • the package is displaced along a conveyor system and has air removed therefrom under a hood which is linked to a subsequent closing mechanism.
  • -displacement means for continuously displacing the package along a horizontal direction while supporting a bottom of the package and holding an upper part of the package at all times;
  • -raising means for raising the bottom of the package along a distance of travel of the package to reduce vertical tension within the package; and -opening means for opening a portion of the upper part of the package while maintaining holding of the sides thereof using a vacuum source acting through a belt system which urges the sides of the package against the belt system during the continuous displacement of the package.
  • Figure 8 is another side close-up view of the upper driving system shown in Figure 4.
  • Figures 11 a and 11 b are front views of the interaction of a package with a system according to another preferred embodiment of the present invention, showing lower and upper positions of the package;
  • Figures 12a to 12c are side views of the interaction of a package with a system according to another preferred embodiment of the present invention, as the package travels along the conveyor system;
  • Figures 14a to 14d are perspective views of the interaction of a package with the system shown in Figure 11 , illustrating air extraction, vacuum shutdown and maintaining of the condition of the package after extraction.
  • A. Module receives packages from packaging machine.
  • the upper part of the bag is not held before and during air extraction.
  • the upper part of the package is continuously held, even during air extraction, ensuring an exact positioning of the upper part of the bag, thus ensuring a constant transfer to the closing system and an increase in the closing system reliability and quality of the finished product.
