Definitions

  • the present invention relates to a package conditioning machine including pneumatically insulated chambers.
  • the preamble of claim 1 is based on US-A-3 545 983.
  • machines are divided into two categories: the first comprises those machines that have a big chamber inside which several packets are simultaneously conditioned; the second category includes machines that show a plurality of different small conditioning chambers, everyone conditioning a single packet.
  • the simultaneous conditioning of several packets requires highly voluminous structures, owing to the wide areas of accumulation and to the need to employ together several chambers for the loading, conditioning and unloading operations. Furthermore, inside the conditioning chamber the packets must be carefully placed in order to allow the action of multiple sealing jaws, that don't permit, even if regulated, the same precision on every single sealed packet.
  • Said machines have moreover problems related to the overall dimensions, due to the opening and closing operations of covers and doors.
  • the most pertinent prior art - USA- A-1.589.452 has a plurality of covers for the chambers of the turret ; it is therefore difficult to operate said device.
  • This invention represents an optimal solution to the specific problems of the above-described machines by designing a machine which is characterized by the features of claim 1.
  • Figure 1 schematises a perspective view of the machine, which comprises a single cover for closing and opening different conditioning chambers set up in a revolving turret. It can be noticed that the opening and closing of the conditioning chambers is achieved by the revolving of the turret and not by the lifting of the cover. This feature removes any radial or axial overall dimensions problem during the opening operation.
  • Figure 3 highlights the fact that the conditioning chambers are set up in a revolving turret with the mouths laying over the same flat surface.
  • Figure 4 highlights the fact that also the cover has the same plain surface as the turret beneath, and it can be noted that said cover is provided with a passage for the loading and unloading of the packets.
  • Figure 5 is an exploded view of the machine to highlight the configuration of the sealing strip (9) and of the elastic seal elements (10) inserted in the seat (11).
  • Figure 6 is a section of an open conditioning chamber because it is in front of the passage that allows the loading operation. It can be noticed that during this operation the adjacent chambers are pneumatically insulated.
  • Figure 7 is a section of the next conditioning chamber closed by the cover, in order to start the conditioning process.
  • FIG. 8 Figure 8, 9, 10 and 11 indicate different phases of conditioning in the following chambers.
  • Figure 12 indicates the sealing operation of the packet inside the chamber that is still pneumatically insulated. It can be noticed that the sealing device is placed on the cover and it's only one for all the conditioning chambers.
  • Figure 13 is a section of a conditioning chamber that is open because, at the end of the conditioning cycle, it is again in front of the passage that allows the unloading operation.
  • Figure 14 and 15 show in section a variation of the machine equipped with similar conditioning chambers, but presenting also a bottom mouth and its cover to allow the operation of loading from above and unloading from below.
