Definitions

  • the neck of the bags always has the same peripheral dimensions, the device operates satisfactorily. However, when the effective circumference of the neck is less than the predetermined minimum dimension, the bag is frequently damaged at the time the mandrel is inserted, or bursts while being inflated. On the other hand, if the peripheral dimension of the bag is relatively too large, the pressure introduced into the bag is insufficient to inflate it, or an arrangement must be provided to automatically increase the air supply.
  • Another aspect of the present invention resides in the provision of a packaging apparatus in which the resilient collar is made of an open pore foam-like material to enable that the resilient collar can deform easily and adapt itself to the dimension of the bag opening without damaging the bag.
  • FIG. 1 is a schematic side view of the apparatus showing the bags below the mandrels;
  • FIG. 2 is a view similar to FIG. 1, illustrating the bags in situ
  • FIG. 3 is a cross sectional view taken along line Ill- -III of FIG. 2.
  • each tubular mandrel 2 substantiallytransversely to the longitudinal axis thereof, is a retaining plate 6 carrying secured to its bottom face a resilient collar 7 which circumferentiallyencloses the mandrel 2.
  • the mandrels 2 are jointly attached to a support means 8 composed of a suspending rod and plate structure, with the rod receiving an arm 9 which in turn is connected to 'a rotatable shaft 10.
  • the shaft 10 is mounted in a bearing 11 so that it can move parallel with the axis of the bag to be inflatedand the shaft is raised and lowered by means of a drive, not shown.
  • the bags 1 to be inflated are placed in a pro-opened condition below mandrels 2 by means of a conveyor device known per se, but not shown, for example, conveyor tongs fitted to a chain.
  • the mandrels 2 are then lowered into the bags until the flat bottom face of each resilient collar 7, which extends perpendicular to the length direction of the bag, abuts edge 12 of openings 13 of the bag so as to establish a seal therebetween.
  • the insertion of the mandrels 2 into bags 1 causes the opening of the bags to be widened. Thereafter, air is blown through the nozzle outlets 3 into the bags to completely open them. The air supply is shut off before mandrels 2 are withdrawn. During this process step, the seal between the edges 12 and the collar is maintained.
  • the resilient collars 7 are preferably made of an elastomeric porous foam material, or an equivalent thereof. As already .indicated above, the bottom faces of collars 7 are biased against edges 12 of bags 1 into an abutting relationship, causing a slight deformation without, however, doing damage to the peripheral edges 12. A certain amount of the air can escape through the pores of the foam material, thus restricting the pressure within the bags within certain limits, thereby establishing a degree of air pressure control. This ensures that the bag will be adequately inflatedbut will not burst.
  • the cross section of mandrel 2. in the vicinity of its upper end, is suitably selected to be similar to the cross section of the filler connection of a bag filling device, not shown.
  • the mandrel 2 and the filling device can both be aligned with the path along which the bag is conveyed on the pack-again machine (not shown). This has the advantage of ensuring that the openings 13 of the inflated bags are positioned to coincide correctly with that of the filling device.
  • the arrangement of the resilient collars 7 makes it possible to inflate bags of a variety of circumferential dimensions utilizing a single mandrel; the main consideration being that the edge 12 does not protrude beyond the radial periphery of the collar.
  • a mandrel of a different size may be desirable or necessary when the cross section of the filling device outlet is not suitably designed to accept such other sizes.
  • At least one of retaining plates 6 is, optionally, adjustable in height relative to the mandrel which carries the plate, so that the depth of penetration of one bag edge 12 into the resilient collar 7, is independent of the penetration of the adjacent bag of the second collar.
  • a packaging system having an apparatus for inflating bags, comprising:
