  • This invention relates to packaging machines which convert tubular, heat-sealable packaging material into filled and sealed bags or packages, and has particular reference to such a machine which is, at least partially, actuated pneumatically.
  • a tube of the plastic packaging material is pulled over a filling pipe through which the merchandise to be packaged is fed, and the machine is provided with sealing jaws, below the filling pipe and on either side of the tube, adapted to open and close in a direction transverse to the tube axis in order to produce a transverse seal in the tube after each charge of merchandise is delivered into it.
  • the jaws are also adapted to move back and forth in a longitudinal direction for the purpose of intermittently advancing the tubular material.
  • Such machines are well known in the art.
  • the invention is predicated upon the discovery that this desirable objective can be achieved in an admirable manner by providing a pneumatic piston-cylinder device for operating the jaw-moving mechanism, especially the mechanism controlling the transverse opening and closing of the jaws.-
  • a pneumatic piston-cylinder device for operating the jaw-moving mechanism, especially the mechanism controlling the transverse opening and closing of the jaws.
  • An additional special feature of the invention resides in the fact that the piston-cylinder arrangement and'its associated linkages, travel with the jaws during the longitudinal movements of the latter.
  • FIG. 1 is a fragmentary side elevational View of a machine embodying the features of this invention, certain parts being shown in cross-section;
  • FIG. 2 is a front elevational view of the essential parts shown in FIG. 1;
  • FIG. 3 is a cross-sectional view substantially along the line IIIIII of FIG. 2;
  • FIG. 5 is a view ofthe latch mechanism shown in FIG. 1, this view being in the same direction as FIG. 1 and showing the mechanism by itself;
  • FIG. 6 is a diagram of the cycle of operation of the machine.
  • a column or post 1 is mounted for reciprocating movement in a vertical direction within a suitable framework (not shown).
  • the motive power and the drive shaft for accomplishing this movement have not been shown, and may be of any conventional character.
  • Above the post 1 and in substantial alignment therewith is a hollow filling pipe 5 over which the tubular packaging material 4 is pulled in a downward direction.
  • the packaging material may be supplied in the form of a continuous web which is drawn around a forming element (not shown) surrounding the filling pipe, whereby it is formed into a tube with its longitudinal edges in overlapping relation.
  • Suitable means may be provided for fusing the overlapped longitudinal edges to produce a longitudinal seam.
  • the post 1. is provided at its upper end with a stepped or platform-like section 2 which carries a pair of spaced vertical wings 3 arranged on opposite sides of the tubular material 4. These wings carry the transverse sealing jaws 6 and 7 and the mechanisms which control the opening andclosing of these jaws.
  • These mechanisms include a pair of parallel links 8 articulated to the jaw 6 (see 'FiG. 2 and another pair of similar parallel links 9 artic'ulated to the jaw 7.
  • the links 8 each have one end 8" 'pivotally connected to the jaw 6 and the othe'rend 8 pivotally articulated to one of the wings 3.
  • the links 9 are pivotally connected at 9 to the jaw 7 and at 9" to the wings 3.
  • the links 8 and-9 are located outwardly of the wings 3.

Suitable connections (not shown) including appropriate control valves are provided between a source of fluid under pressure and the inlet 13. slidable hollow piston 14 formed with a hollow piston rod 15. The piston rod is slidably mounted within the upper end of the cylinder 12. region of the piston 14 and piston rod 15 is a compression spring 16, one end of which rests against the floor of the cylinder 12, and the other end'of which presses against the closed upper end of the piston rod.
  • the upper end of the piston rod 15 is formed with a projecting head 17. Pivotally connected to the head 17, and extending in opposite directions therefrom, are connecting'links 18 and 19.
  • the outer end of the link 18 is pivotally connected at 1i? tothe lower end of the lever 10, and similarly, the outer end of the link 19 is pivotally connected at 11 to the lower end of the lever 11.
  • Each of the piston heads. 17 is provided with aroller 21) (see FIGS. 2, '4 and 5) projecting toward the adjacent .wing 3 and arranged with its axis horizontal. Between each head 17 and wingfi, a latch 21. is provided (see FIG.
  • the latch 21 is also articulated at 24' to an actuating arm 24, the opposite end of the arm 24 being keyed at 247m a rocker shaft 34- extending between the wings3 as best indicated in FIG. 2.

  • the spring 16 remains compressed and hence the jaws 6 and 7 remain closed because tube 4 that lies between the pipe 5 and the jaws 6 and 7.
  • the electric eye 35 becomes effective, as a result of being actuated by an appropriate marking '36 on the. material 4, to "energize the solenoid 30.
