Definitions

  • the present invention relates to a sealing device in a packaging apparatus for heat-sealing a film by sandwiching a position of a film in which a package is stored at a predetermined interval from the outside of the film.
  • the sealing device in this type of packaging apparatus intermittently conveys, for example, a cylindrical film in which the articles to be packaged are stored at predetermined intervals, installs a holding body above and below the film, and temporarily stops the film conveyance. Above the film, the position between the objects to be packaged is sandwiched from outside of the film by this holding body, and the film is welded by the heat of the heater on the front surface of the holding body, and the position between the objects to be packed of the film is sequentially partitioned and sealed. For example, it is configured such that the middle part of the heat sealing position is cut and intermittently conveyed, so that the packaging bags containing the articles to be packaged are sequentially carried out.
  • the heat-sealing position can be controlled. If there is any debris in the package, there is a risk that heat sealing failure may occur.
  • the object to be packaged is such that mushroom-like debris is apt to come out, small pieces of mushrooms, debris at the portion with a stone, or soil may come out in the film. Even if this is not done, if such debris is pinched and pinched together with the film and heat-sealed, the heat-sealing of the films will be insufficient, and the welded spots will come off after bag making, or There is a possibility that a seal failure may occur, for example, where a portion that does not weld at all may occur.
  • this heat seal portion also serves as a cutting position, and if debris is caught in this portion, defective cutting, breakage or wear of the cutting blade may be accelerated.
  • the present invention is an improvement on such a conventional sealing device, It is an object of the present invention to provide an extremely innovative sealing device for a packaging device that can solve the above problem. Disclosure of the invention
  • the present invention intermittently conveys a cylindrical film 1 in which a packaged object 3 is stored at a predetermined interval, and holds the film 1 by sandwiching the packaged object 3 in the film 1 from the outside of the film 1.
  • the film push-up body 20 that pushes up the heat sealing position P of the film 1 is provided, so that the lower portion of the cylindrical film 1 is inwardly pushed by the push-up body 20. Even if there is a defective sealing cause 3A such as debris of the packaged object 3 at the heat sealing position P, it is eliminated.
  • the film push-up body 20 is configured to push up and project toward the heat sealing position P before heat-sealing the cylindrical film 1, so that the By previously pushing up the film with the film pushing-up body 20, the defective sealing cause 3A is removed from the heat sealing position P, and the sealing failure due to the penetration can be prevented.
  • a lower holding member 21 and an upper holding member 22 are arranged above and below the cylindrical film 1 in the width direction of the film 1, and the film 1 is held between the two holding members 21 and 22.
  • a gap 23 is provided in the middle of the lower holding body 21 along the width direction of the cylindrical film 1.
  • the film push-up body 20 Before the lower holding body 21 is raised and heat-sealed, the film push-up body 20 is positioned in the two heat sealing positions P. It works up to the head With this configuration, it is possible to easily remove the seal failure cause 3A from the heat seal position P simply by controlling the film push-up body 20 to drive up the film push-up body 20.
  • An extremely practical packaging device that can easily apply the present invention to a sealing device. An apparatus can be provided.
  • a cutting device 7 is provided by arranging a blade plate 7A for cutting the middle part of the two heat sealing positions P at the middle part of the upper holding body 22 so as to advance and retreat.
