Definitions

  • bales are typically fairly large and, as a consequence, require large sheets/webs of plastic film capable of surrounding the bales. Additionally, such bales vary in size (length, width and height) and hence are difficult to consistently and snugly envelop in plastic film.
  • the present invention is directed to a joining apparatus used in an apparatus for forming elongate film into a tube around articles, the forming apparatus including: a conveying surface adapted to carry the articles being wrapped; a forming collar adapted to wrap film around the articles carried on the conveying surface, the forming collar including left and right sections, the left section located adjacent a left side of the conveying surface and the right section located adjacent a right side of the conveying surface; wherein the left and right forming collar sections each include an inside surface, an outside surface and a leading edge; wherein elongate film having a central area and left and right sides is formed into a tube by directing: the central film area onto the conveying surface; the left film side along the forming collar left section outside surface, around its leading edge and along its inside surface; and, the right film side along the forming collar right section outside surface, around its leading edge and along its inside surface; wherein the formed tube includes an elongate overlap region whereat the left film side is arranged adjacent to and
  • the apparatus for joining the left and right film sides to one another at the overlap region includes an outside shoe adapted to be located outside the formed tube adjacent the overlap region and an inside shoe adapted to be located inside the formed tube adjacent the overlap region whereby the overlap region may be sandwiched between the outside and inside shoes. Hot air is selectively directed to the overlap region whereby the first and second plastic film sheets are heated and joined to one another.
  • the outside shoe includes a face adapted to slidingly engage the plastic film overlap region and an air delivery groove extending into the outside shoe from a delivery groove opening in the face.
  • the hot air is selectively provided under pressure into the groove and exits through the air delivery opening whereby the hot air is directed onto the plastic film overlap region.
  • the groove is elongate and extends in the longitudinal direction of the formed tube.
  • the elongate groove has an ingress end closest to the forming collar and an egress end opposite the ingress end.
  • the inside shoe includes an inside shoe face adapted to slidingly engage the plastic film overlap region and an inside groove extending into the inside shoe from the inside face.
  • the inside groove is elongate and extends in the longitudinal direction of the formed tube.
  • the inside elongate groove has an ingress end closest to the forming collar and an egress end opposite the ingress end.
  • the inside groove is adapted to be located adjacent to and facing the outside shoe groove with the plastic film overlap region therebetween.
  • an outside roller is located adjacent the outer shoe groove egress end and has an outside bearing surface.
  • An inside roller is located adjacent the inner shoe groove egress end and has an inside bearing surface.
  • the outside bearing surface is adapted to be located adjacent to and facing the inside bearing surface with the plastic film overlap region therebetween.
  • the outside roller bearing surface is comprised of silicone rubber.
  • the outside shoe is preferably selectively moveable between an operative position adjacent the plastic film overlap region and an idle position away from the plastic film overlap region.
  • a guiding post is mounted to the outside shoe and slidingly engages a supporting mount, whereby the outside shoe is guided between its operative and idle positions.
  • a pneumatic cylinder is connected between the outside shoe and the supporting mount and is selectively energized for moving the outside shoe between the operative and the idle positions.
  • the apparatus for joining the left and right film sides to one another at the overlap region includes an outside shoe adapted to be located outside the formed tube adjacent the overlap region and an inside shoe adapted to be located inside the formed tube adjacent the overlap region, whereby the overlap region may be sandwiched between the outside and inside shoes. Hot air is selectively directed to the overlap region whereby the first and second plastic film sheets are heated and joined to one another.
  • An inside roller is located adjacent the inner shoe and has an inside bearing surface.
  • the outside bearing surface is adapted to be located adjacent to and facing the inside bearing surface with the plastic film overlap region therebetween.
  • a manifold is located within the air delivery groove and has a plurality of hot air distribution holes. The hot air is adapted to travel through and be distributed by the manifold along the air delivery groove.
  • the present invention is directed to an apparatus for joining a first plastic film sheet and a second plastic film sheet to one another, the plastic film sheets being arranged adjacent to and overlapping one another at an overlap region.
  • the joining apparatus includes a first shoe adapted to be located adjacent the first plastic film sheet at the overlap region and a second shoe adapted to be located adjacent to the second plastic film sheet at the overlap region, whereby the overlap region is sandwiched between the first and second shoes. Hot air is directed to the overlap region whereby the first and second plastic film sheets are joined to one another.

Abstract

L'invention concerne un appareil et des procédés d'assemblage, au moyen desquels un film plastique est formé en un tube de taille variable pour recevoir et envelopper divers articles de grande taille, tels que des balles de coton, de déchet, de tissu, etc.. L'appareil d'assemblage assemble la région de chevauchement du tube de film plastique pour sceller et créer efficacement le tube de film plastique. L'appareil d'assemblage comprend un châssis interne situé dans le tube formé. La région de chevauchement coulisse sur le châssis interne au moment où le tube est formé. Un châssis externe est mobile entre une position de repos éloignée du châssis interne et une position de fonctionnement adjacente au châssis interne. Lorsqu'elle est en position de fonctionnement, la région de chevauchement est prise en sandwich entre les châssis externe et interne et l'air chauffé est mis sous pression à travers une rainure sur le châssis externe et sur la région de chevauchement pour chauffer et assembler efficacement les feuille de plastique qui se chevauchent.
