Abstract

Packaging machine with forming tube (1) around which a ribbon of flexible material (2) is wrapped, in order to shape a continuous sleeve (7), longitudinally sealed (3) to obtain, with subsequent transversal sealings (8, 9), filled and sealed packages, characterized by the fact that it is equipped with a shaping device (14) that produces on said sleeve, along the part between two transversal subsequent sealings, a gusset (14) that is able to constitute the bottom structure of the package, that will have, when turned and placed over a horizontal ground, the necessary base to stand up steadily in vertical position.

Description

  • TECHNICAL FIELD: the present invention relates to the field of packaging machines generally included in the international classification B65 b.
  • STATE OF THE ART: there are several kinds of packaging machines with forming tube around which a ribbon of flexible material is wrapped, in order to shape a continuous sleeve. This sleeve is longitudinally sealed to obtain, with subsequent transversal sealings, filled and sealed packages; it is already known that the envelopes, if placed on a horizontal ground, can only lie flat.
  • In EP 0620156, that concerns a method to obtain stand-up pouches from a sleeve of flexible material wrapped around a vertical forming tube, and discloses a machine according to the preamble of claim 1, the figure 4 discloses a touching device 13 performed at one side of the sleeve. Neverthless said touching device and the longitudinal sealing of the sleeve are not arranged opposite each other. Consequently said longitudinal sealing of the sleeve results in the central zone of the packet and his attractive is non agreeable.The market trend of the packaging field requires at present packages that are able to stand up steadily when placed on a horizontal ground, in order to have a better presentation in display or sale points.The problem to be solved is to obtain, with a machine for envelope production, packages that are able to stand up steadily on a horizontal ground.
  • The present invention is an optimal solution to the problem for the simplicity and the inexpensiveness of the realization and for the great reliability and versatility of employment in the packaging process with forming tube. This is done with the machine according to claim 1.
  • DESCRIPTION: the invention is now disclosed in detail referring to the figures of the attached drawings, as a not limitative example.
  • Figure 1 is an axonometric view that schematizes a packaging process with forming tube around which a ribbon of flexible material is wrapped, in order to shape a continuous sleeve. Said sleeve is longitudinally sealed to obtain, with subsequent transversal sealings, filled and sealed packages.
  • It can be noticed that the ribbon of flexible material comes out from a roll and the product to be packaged is fed by gravity through the forming tube.
  • Figure 2 shows with more details the performance of the transversal sealings and the action of the device that makes on the sleeve a gusset that constitutes the bottom structure of the resulting packages.
  • Figure 3 shows the advancement of the sleeve during the phase in which the transversal sealing device is open. It can be noticed that the shaping device can act also when the sleeve in moving forward.
  • Figure 4 shows in detail the operation of longitudinal sealing obtained by thermosealing together the two opposite facing ends of the internal side of the sleeve.
  • Figure 5 shows the shaping device set on the side opposite to the one where the longitudinal sealing of the sleeve is carried out. It can be noticed that the forming tube is appropriately profiled in correspondence with the shaping device that forms the gusset.
  • Figure 6 shows the characteristic structure of the bottom that allows the package, when turned and placed on a horizontal plane, to stand-up steadily in a vertical position.
  • Figure 7 shows a device to ease the opening of the packages: it is clear that said device is set by the longitudinal sealing of the sleeve.
  • Figure 8 shows the application, by the longitudinal sealing of the sleeve, of a device for pouring and hermetically reclosing the package.
  • Figure 9 shows the application of a ribbon for the tear-off opening of the package.
  • Figure 10 shows the device that, in correspondence with the longitudinal sealing, can include shaped slots.
  • Figure 11 shows a package equipped with a zip fastener for reclosing.
  • Figure 12 shows the application, by the longitudinal sealings, of zip fasteners coming from a roll.
  • In the figures of the attached drawings each single detail is marked as follows:
    • 1 is the forming tube through which the product to be packaged is fed.
    • 2 is the ribbon of flexible material that is wrapped around the forming tube
    • 3 is the longitudinal thermosealing made by compressing the two facing ends of the internal side of the sleeve against each other.
    • 3' is the device that performs the longitudinal thermosealing.
    • 4 is a hopper to put the product to be packaged in the forming tube.
    • 5 is the device with drive belt to make the tubular sleeve move forward.
    • 6 is the station where subsequent sealings, transversal to the sleeve, are performed in order to seal the package.
    • 7 is the tubular sleeve
    • 8 and 9 are two subsequent sealing transversal to the sleeve.
    • 10 and 12 are the two ends of the flexible ribbon.
    • 11 is the internal side of the sleeve
    • 13 is the bottom of the package
    • 14 is the gusset made on the sleeve
    • 14' indicates schematically the shaping device that creates the gusset on the sleeve longitudinally sealed on the opposite side.
    • 15 is the schematization of a device for the tear-off opening of the package.
    • 16 is the pouring and reclosing device applied in the package inside the longitudinal sealing of the sleeve.
    • 17 is the ribbon for the tear-off opening of the package.
    • 18 indicates a profile of the forming tube by the shaping device.
    • 19 indicates the roll of the ribbon for the tear-off opening of the package. It can be noticed that the ribbon is applied continuously during the unrolling of the flexible material roll.
    • 20 is a slot punched on the longitudinal sealing.
    • 21 is a zip fastener, coming from a continuous roll, inserted in line during the longitudinal sealing.
  • The clearness of the figures enlightens the simplicity of the operation of the devices object of the present invention. It is here disclosed that said devices can be used also for machines without a vertical forming tube, but presenting an inclined or horizontal structure also with forced feeding.
  • The invention is obviously susceptible to several usage variations for what concerns the overall dimension, the structural proportioning and the technological choices.
  • All those packaging machines with forming tube, realized according to the characteristics hereinafter claimed will be therefore included in the context of the present industrial invention.
