  • teeth of the blade cut a transversely extending series of perforations adjacent to a transverse seal. Accordingly, the machine outputs a continuous string of connected sealed packages having a transversely extending perforation between adjacent packages.
  • the reciprocating jaws may be limited to only reciprocal motion.
  • the toothed blade may have a series of teeth spaced equidistant from each other, or a series of pairs of teeth spaced equidistant from each other.
  • each tooth of the blade may comprise wedges along laterally opposed sides of the tooth, the wedges each terminating in a cutting edge along a peripheral edges of the tooth, the laterally opposed wedges converging in a sharp point at a leading edge of the tooth.

  • FIG. 10 is a view of the other side of the toothed blade of FIG. 6.
  • FIG. 1 An exemplary vertical form, fill, seal packaging machine is shown diagrammatically in FIG. 1. This drawing is simplified and does not show the cabinet and support structures that typically surround a machine 100.
  • Packaging-film 110 is unwound from a roll 112 of film and passed through tensioners 114 that keep it taut.
  • Packaging-film is typically polypropylene, polyester, paper, polyolefm extrusions, adhesive laminates, and other such materials, or layered combinations of these film materials.
  • a metalized or barrier layer may be used to form the inner-most layer.
  • the packaging-film 110 passes from the tensioners 114 over a former 116, which directs the packaging-film into a vertical tube around a product delivery conduit 118. As the tube is pulled downward by drive belts 120, the vertical tube of film is sealed along its length by a vertical sealer 122, thereby forming a film tube 133 having a continuous longitudinally extending back seal 132.
  • the machine applies the pair of heat sealing jaws 126, 128 against the film tube 133 to form a pair of transverse seals 134, 136.
  • One of the pair of transverse seals acts as the top seal of a package created by that cycle, and the other part of the transverse seal acts as the bottom seal of the next package that will be made in the machine.
  • the heat seal jaws also includes a blade that reciprocates in an orbital motion to cut along a line that extends between the pair of seals 134, 136 to release the formed and filled packages 130 sequentially.
  • the prior art cannot produce a continuous string 135 of packages 130 that have a transverse tear line 138 between adjacent packages for ease of subsequent separation of the string into individual packages, as illustrated in FIG. 2, for example.
  • an exemplary embodiment of heat sealing and perforating jaws shows a pair of jaws 126, 128 that include a toothed blade 150 located between the two heating surfaces 142, 144, of one jaw.
  • the toothed blade 150 may be held fixedly but releasably in position mounted to the jaw.
  • a shank portion of each tooth projects out from the body of the blade and terminates in a head that forms part of a leading edge of the blade.
  • the leading edge 152 projects beyond the leading end 127 of the jaw such that the teeth 154 of the blade (seen more clearly in FIGS.
  • the teeth 154 on the leading edge 152 may project into a slot 146 in the opposing jaw after penetrating the packaging-film to avoid inadvertent blunting or other damage to the sharp pointed tips 156 of the teeth 154.
  • FIGS. 5-10 Exemplary non- limiting embodiments of toothed blades 150 are illustrated in FIGS. 5-10. These embodiments may be mounted in a fixed position in a recess in the jaw 128, for example, using the exemplary locating and positioning features 162, 164. Thus, these blades move in unison with jaw 128.
  • FIGS. 5-7 has a shank portion projecting out from the body of the blade and terminates in a head portion that includes teeth 154 grouped in pairs, albeit that other multiples in a group may also be used.
  • the exemplary embodiment of FIGS. 8-10 has equidistantly spaced individual teeth 154; each tooth having a shank portion projecting out from the body of the blade and terminating in a sharp head portion. While the illustrated examples have teeth or grouped teeth spaced apart equidistantly, such even spacing, while perhaps aesthetically desirable, is not essential for producing tear lines 138 to separate a continuous string of separable packages.
  • the head portion of teeth 154 have wedges 158 on only one face or surface of the blade 150, while the shank portion is free of such sharpening wedges.
  • the wedges 158 extend along the opposed sides of the teeth, tapering to sharp cutting edges at the peripheral edges of each tooth.
  • the wedges from the opposing sides converge in a sharp pointed tip 156 of each tooth that is able to penetrate packaging-film during normal operation of the vertical form, fill and seal machine.

  • the blades 150 are planar, and the teeth 154 are coplanar with the blades, and do not project out of the plane of the blades 150 either upward or downward.
  • packaging-film is unwound from a film-dispensing roll 112 of the machine 100.

  • the film tube 133 is then sealed with a pair of reciprocating jaws that include a toothed blade 150 located between a pair of heat sealing elements 142, 144.

Abstract

L'invention porte sur une machine de formation, de remplissage et de scellement verticale, laquelle machine comprend une paire de mâchoires à va-et-vient, disposées au-dessous de la conduite d'alimentation en produit de la machine. Les mâchoires sont mutuellement espacées de façon à permettre au tube de film sortant de la conduite d'alimentation en produit de passer entre les mâchoires après que le tube de film se sépare de la conduite d'alimentation en produit. L'une des mâchoires à va-et-vient comprend une lame dentée comportant un bord avant de la lame dentée s'étendant au-delà d'un bord avant de la mâchoire. Quand la paire de mâchoires se ferme, les dents de la lame coupent une série de perforations s'étendant transversalement adjacentes à un scellement transversal. Par conséquent, la machine délivre en sortie une chaîne continue d'emballages scellés reliés comportant une perforation s'étendant transversalement entre des emballages adjacents.
