Definitions

  • the object of the present invention is to constructively simplify a tray sealing machine for packaging trays which have products that contain the edge of the tray.
  • At least one depression around a dome or around all domes is provided at least partially, preferably closed, circumferentially.
  • the lidding foil can be held on all four sides around the dome or domes even during the molding process.
  • the cover film is thereby deep-drawn or formed at least partially into the depression.
  • the settable under vacuum recess thus generates a high holding torque in addition to the static friction of the lid film on the underside of the sealing tool shell.
  • the depression is a U-shaped or V-shaped groove, since it is easy to manufacture and suitable for deep-drawing or shaping the cover film into this groove.
  • Under a U-shaped groove is also a rectangular shape, as used for inserting sealing cords to understand.
  • the recess comprises a dome-oriented edge for vacuum-forming the lid film around the edge. This creates a very high holding force and counteracts the tensile force through the lid film when molding in the dome.
  • the edge at an angle of at least 70 °, preferably 90 °.
  • At least one or each recess preferably has a width of 1 mm to 5 mm and / or a depth of 0.5 mm to 3 mm.
  • the heating plate is preferably provided on the underside of the sealing tool upper part upstream of a production direction of the cover film in order to have the shortest possible transport path for the cover film from the heating position to the molding position and thus to achieve a very short time span, during which the cover film cools before the molding process.
  • a method for operating a tray sealing machine with a sealing tool upper part comprising at least one dome to form a lid film in the dome is characterized in that before and during the molding of the lid film into the dome (or dome) one outside of Domes or the dome arranged film holding device on the underside of the sealing tool upper part holds the lid film by means of vacuum.
  • the molding process can take place independently of time of transport of the shell and for holding the lid film on the sealing tool shell no clamping frame or sealing tool base is needed. Or the molding takes place by lifting the shell with protruding product therein to the lidding film.
  • the product forms the lid foil into the dome.
  • the phrase "forming the lid foil in the dome” does not necessarily require that the lid foil be applied to the entire surface of the dome. Rather, it is sufficient if the lid foil deforms into the interior of the dome.
  • the cover sheet is formed around an edge of the recess in order to further increase the holding force.
  • the cover film is preferably heated by means of a heating plate before the heated part of the cover film is transported under the dome of the sealing tool upper part.
  • the lidding film is heated to the extent that a plastic deformation during molding in the dome is made possible and in skin films shrinkback and thus a flat concern to the product is possible.
  • FIG. 1 shows a tray sealing machine 1 with a sealing station 2, the shells 20 sealed with a lid film 3, and a gripper system 4, which moves the trays 20 in a transport direction P from a feed conveyor 19 in the sealing station 2.
  • the sealing station 2 has a sealing tool lower part 5 and a sealing tool upper part 6 arranged above it.
  • the cover film 3 is transported intermittently in the production direction P.
  • the stationary lidding film 3 is pulled over the film holding device 9 by means of a vacuum to the underside 10 of the sealing tool upper part 6 and thus the lidding film 3 also bears against the heating plate 7.
  • the voltage applied to the heating plate 7 part of the lid film 3 is heated to the desired or predetermined temperature.
  • the film holding device 9 is deactivated by venting the vacuum openings 12 and the lid film 3 and thus the heated part of the lid film 3 in the production direction P are transported under the dome 8.
  • the film holding device 9 is activated again and the lid film 3 is held.
  • the lidding film 3 is cut according to the contour of the tray edge 22 and then moves the finished packaging produced together with the tray holder and the sealing tool base 5 down and thus the sealing station 2 is opened.
  • FIG. 4 a detail view of the film holding device 9 is shown. It can clearly be seen that the film holding device 9 four recesses 13 which are parallel to each other, in the form of V-shaped grooves in the bottom 10 are provided. The required vacuum is provided via vacuum openings 12 for the individual recesses 13. In this case, the vacuum openings 13 are designed such that each individual vacuum opening 12 is connected to the adjacent recesses 13. To allow a compensation of the vacuum between parallel recesses 13, grooves 14 may be provided which are arranged transversely to the extension of the recesses 13 and establish a connection between the recesses 13.
  • FIG. 5 shows a detailed view as a sectional view of the film holding device 9 with the held under vacuum and molded into the dome 8 lid film 3.
  • the lid film 3 is also partially formed in the recess 13.
  • the lidding film 3 bears against an edge 15 oriented toward the dome 8.
  • This deformation of the cover film 3 at the edge 15 produces a very high holding force of the cover film 3 on the film holding device 9 in order to counteract the tensile force F during the molding process and to hold the cover film 3 securely.
  • the vacuum V Via the vacuum line 11, the vacuum V (see arrow) is generated at the recess 13.
  • FIG. 6a shows a V-shaped groove as a recess 13 with the edge 15 in a sectional view.
  • the Figures 6b and 6c show a U-shaped groove, the FIG. 6b an edge 15 with an angle ß of 90 °.
  • the edge 15 of the FIG. 6c has an angle ß of about 75 ° and a groove base 16 is rounded, while the groove bottom 16 in FIG. 6b is rectangular.
  • FIG. 6a also the width B and the depth T of the recess 13 are shown.
  • FIG. 7 shows a shell 20 with a product 21, which projects far beyond a shell edge 22.
  • the tray sealing machine 1 is particularly well suited to seal very high products 21, which are in very shallow bowls 20, with the lidding film 3.
  • this can also be applied to the inner sides 23 of the shell 20.
  • heating plate 7 is not integrated in the sealing tool upper part 6, but is provided as a separate workstation in front of the sealing tool upper part 6.
  • a heating plate 7 is also optional provided, since very thin and flexible lidding sheets 3 do not require heating to be formed in the dome 8.
  • the term “forms" is to be equated with the usual term "deep drawing”.
  • the lidding film 3 is vacuum formed in the mandrel 8 before a sealing tool base 5 with a shell 20 in which a projecting over a shell edge product 21, with the sealing tool shell 6 forms a vacuum chamber to the interior of the shell 20 to evacuate and / or aerate and then seal the lid film 3 with the shell 20.
  • the dome 8 may also be heated to reheat the lidding film 3 so that it can rest tightly against the product 21 after venting.
