  • the system also comprises a deaeration port 20 located above the upper driving system 16 connected to the vacuum source 18 that allows removal of air from the interior of the package 12 when the package is positioned under the deaeration port 20 by the upper driving system 16 and the lower conveyor system 14, under the bag-opening sub-system.
  • the deaeration port can be an aspiration port, a dedusting port, a vacuum port, a system connected to a vacuum source or any other equivalent system known to the person of skill in the art which is capable of removing air or substances from the package.
  • the lower conveyor 14 includes a steel frame 30, conveyor rollers 32 and a conveyor belt 34.
  • the conveyor belt is driven by a motor 36 at a constant linear velocity in order to displace the package towards the closing or sealing systems located downstream.
  • the steel frame has a shape 38 that allows the conveyor belt and the package to rise along a certain height while translating along the system.
  • the system 40 controlling the upper part of the package has three sections, 42,44,46.
  • the first 42 and third 46 sections are made of aluminum blocks, pulleys and belts.

  • the mid-section of the system 44 includes aluminum blocks 50 having a special shape, perforated belts 52, pulleys 54 and various other pieces of hardware.
  • a tube 56 connected to a high debit ventilator removes the air through an opening in the aluminum blocks and through the perforated belt.

  • the package arrives from the packaging system with a certain quantity of air inside thereof, in addition to the packaged product.
  • the product reaches a certain height within the package.
  • the upper part of the package which is not filled is designated as the freeboard.
  • the sides of the freeboard approach one to another. Raising the package using the shape of the bottom conveyor will result in loose freeboard.
  • the blocks in the deaeration section have a special internal curvature.
  • the belts are assembled in a manner such that there is a greater length on the side on which the belts face each other to follow the curvature.
  • the source of vacuum produced by the high flow ventilator which removes the air from behind the belts constrains the belts to follow the curvature of the block.
  • a certain quantity of air passes through them so that the upper sides of the package are constrained to follow the belt and curvature of the block.
  • A. Module receives packages from packaging machine.
  • FIGS 11 to 14 illustrate various aspects of the system during operation.
  • Figures 1 1 a and 11 b show lower and upper positions of the package along the conveyor illustrating how tension is removed from the top of the package once it is lifted.

  • the present invention offers the following performance parameters:
  • a method removing air from an interior of a flexible package before closure thereof comprising the following steps: a) displacing the package along a horizontal direction; b) maintaining continuously an upper part of the package closed along a significant length of its displacement; c) partially opening the upper part of the package at a specific location along the length of the system; and d) removing air from the interior of the package when the package is positioned, at said specific location.
  • the method further comprises the step of decreasing, along the length of the displacement, a distance between a means for displacing the package in step a) placed under the package and a means for maintaining the package closed in step b) to remove vertical tension from the upper part of the package.
  • a package after going through the above-described deaeration system or method, can then be sealed or closed using any sealing or closing system known in the art.
  • the open package goes through the hood and it is gradually closed by the belts facing each other and located in the upper part.
  • the package is closed when it arrives at the air removal section (the package is held by the upper driving system belts) and it is partially opened. In fact, a portion of it stays closed while it is still held by the belts. This partial opening is done while the package is moving forward.
  • 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.
  • the upper part of the package is not held before the end of air extraction; whereas in the present invention, the upper part of the bag is continuously held.
  • the distance between the conveyor which supports the lower part of the package and the belts supporting the upper parts of the package is adjustable. Consequently, it is possible to control tensions exerted to the sides of the package when the air is extracted from it. Since the distance between the conveyor supporting the lower part of the package and the belts holding the upper part of the package is controlled, the condition (behaviour) of the flap is also controlled and the distance between the closing system and the product level into the bag is decreased which reduces the freeboard required.

Abstract

L'invention porte sur un système permettant le retrait d'air de l'intérieur d'emballages souples, dans lesquels peut se trouver un matériau, lequel système comprend un transporteur transportant et supportant la partie inférieure d'un ou plusieurs emballages souples, un deuxième sous-système maintenant la partie supérieure de l'emballage, et un système d'extraction d'air. L'emballage est soulevé verticalement tout en étant déplacé le long du transporteur. Le retrait de l'air des emballages avant leur fermeture produit un volet plat et droit, tout en réduisant la distance entre le produit et le raccord scellé ou cousu. Le processus est accompli à l'aide d'un déplacement continu de l'emballage. Ces avantages conduisent à des économies de matériau d'emballage. L'invention porte également sur un procédé permettant le retrait d'air.
