Definitions

  • the present invention relates to a device and a method for coating packaging and a coated packaging.
  • trays are lined with an oxygen-barrier plastic composite film and then sealed after being filled with a top film.
  • the packages are separated along the edge of the shells in a separating system of the plastic composite film and the top film and the plastic composite film ends in the finished packaging flush with the shell edge.
  • protruding edges of the coating there is a risk that it will detach from the shell at individual points. If the overhanging of the edge is to be prevented by an accurate cutting, a complex exact positioning of the packaging must be carried out prior to the cutting and there is a risk that the edges of the shell will be damaged. This problem occurs in particular when a shell of a porous plastic material such as foamed polystyrene is to be used.
  • a package can be produced in which it is reliably prevented that the sheet material used for coating the shell protrudes at the edges. Furthermore, the production of packages does not require such a precise positioning even with a sensitive shell material as in the known methods, so that a more effective, faster production can take place.
  • the device according to the invention enables a fast and efficient production of the desired packaging in a few steps.
  • the packaging has a lower part in the form of a shell 1, which in the embodiment shown has a substantially rectangular cross section and forms a trough 10 for a product to be packaged.
  • the shell 1 has a peripheral upper edge 13, which is substantially planar, and outer side edges 14, which extend substantially vertically.
  • the trough 10 is lined with a moldable sheet-like material 3 as a coating, which rests against the inner bottom wall 11 and the inner side walls 12 of the shell 1.
  • the sheet-like material 3 also covers the circumferential upper edge 13.
  • the lateral edge 3a of the sheet-like material 3 abuts in an upper portion 14a of the outer side edges 14. Over the entire contact surface between the moldable sheet material 3 and the shell 1 they adhere to each other, wherein the adhesion is generated in the illustrated embodiment by a thermal sealing by means of heat.
  • the package has a cover part 2, which is formed by a second sheet-like material, which is sealed in the region of the peripheral upper edge 13 on the coating applied there from the moldable sheet material 3.
  • the cover part 2 has a protruding portion 2a.
  • the lid part 2 can be grasped and the seal with the moldable sheet material 3 can be released to open the package.
  • the sealing of the moldable sheet material 3 with the shell 1 on the one hand and with the cover part 2 on the other hand is formed so that the web-shaped material 3 does not detach from the shell 1 when opening the lid part 2.
  • the interior of the shell has a hermetically sealed controlled atmosphere prior to initial opening.
  • the atmosphere may be evacuated and replaced with an inert gas such as CO 2 as a replacement gas.
  • the moldable sheet material which is formed in the described embodiment by a thermoplastic resin film, from a supply roll 4 is unrolled.
  • a heating and forming station 6 In the working direction of the packaging machine (from right to left in Fig. 7) behind the feeder 5, a heating and forming station 6 is provided, in which the moldable sheet material 3 is formed in the wells 10 of the shells 1.
  • the heating and forming station 6 is formed as a thermoforming station, in which the trays 1 are lined by deep drawing with the moldable sheet material 3.
  • the moldable sheet material 3 is first heated and then formed by a pressure difference generated in the wells 10 of the shells 1. After this station, the trays 1 are connected to the moldable sheet material 3.
  • the trays 1 are made of a porous foamed plastics material such as e.g. made of foamed polystyrene and are themselves gas permeable, so they can serve directly as a mold for the deep drawing process.
  • the trays 1 are transported with the already coated troughs 10 together with the feed of the moldable sheet material 3 in a cutting and edge sealing station 7.
  • the coated shells 1 from the moldable web-shaped material 3 separated and laterally over a shell protruding side edge 3a of the sheet-like material 3 is sealed to the upper portion 14a of the side edges 14 of the respective shell 1.
  • a winding device 8 is provided, in which a remaining skeleton 3 'of the moldable sheet material 3 is wound up after the peeling of the coated shells. Behind the winding device 8, a discharge device 9 is provided for the coated shells produced.
  • FIGS. 3 to 5 each show a schematic sectional view of the cutting and edge sealing station 7 transversely to the transport direction.
  • the packaging machine shown is designed for the simultaneous processing of two shells 1 perpendicular to the transport direction.
  • the cutting and edge sealing station 7 consists of a cutting device 20 and a edge sealing device 30.
  • the cutting device 20 has a frame 21, are fixed to the cutting blade 22, which are arranged in the illustrated embodiment, in the first position shown in Fig. 3 below the path of the sheet material 3.
  • the frame 21 is attached to a lifting device 23, the frame 21 with the cutting blades 22 of the in Fig. 3rd shown first position in the second position shown in Figs. 4 and 5 can move.
  • the lifting device 23 is realized by a piston-cylinder arrangement.
  • the cutting blades 22 are arranged so that they run around when introduced into the cutting and Randsiegelstation 7 shell 1 around outside of the outer contour on the opposite side of the web of the sheet-like material 3.
  • the edge sealing device 30 has a sealing tool 31, which is connected to a lifting device 32.
  • the sealing tool 31 is formed by two sealing tools 31a and 31b provided for two packages to be processed in parallel but identical in construction. Also shown are two lifting devices 32a and 32b in the form of piston-cylinder arrangements, which, however, may also be designed as a single lifting device 32. For the sake of simplicity, only one sealing tool 31 and one lifting device 32 will be described in the following.
  • the lifting device 32 is designed such that it can move the sealing tool 31 from the first position shown in FIGS. 3 and 4 into the second position shown in FIG. 5. In the first position shown in FIGS. 3 and 4, the sealing tool 31 is located below the plane spanned by the web-shaped material 3.
  • the sealing tool 31 is designed to be heatable and has a circumferential projecting edge 33.
  • the circumferential projecting edge 33 is adapted to the outer contour of the shells 1 and arranged so that in the second position when inserted into the cutting and Randsiegelstation 7 shell 1 surrounds its outer contour all around along an upper portion 14 a of the outer side edge 14 and the web-shaped material 3 presses against the upper portion 14a.
  • the circumferential projecting edge has an inner wall 34 extending substantially parallel to the direction of movement of the edge seal 30 from the first position to the second position. It can also be seen that the circumferential projecting edge 33 on the side of the inner wall 34 has a tapered surface 35 towards its free end.
  • the trays 1, which are already lined with the formable sheet-like material 3, are held between an upper abutment 40 and a lower abutment 41 in a tray receiving position.
  • the upper abutment 40 is fixed to an upper frame 42 of the cutting and edge sealing station 7, and the lower abutment 41 is fixed to a lower frame 43 of the cutting and edge sealing station 7.
  • This extension plane E extends perpendicular to the direction of movement of the edge-sealing station from the first position to the second position.
  • the upper frame 42 can be moved with the anvil 40 in the direction of the arrow 44 from the closed position shown in FIGS. 3 to 6 into an open position in which the trays 1 are inserted into the cutting and edge sealing station 7 and out of this can be removed.
  • the trays 1 are unstacked from the feed device 5 to the unrolled from the supply roll 4 formable sheet material 3. Subsequently, the moldable sheet-like material 3 is formed in the heating and forming station 6 in the wells 10 of the shells 1, wherein this operation is clocked in a main machine cycle. Subsequently, those with the malleable sheet-like Material 3 clothed trays 1 transported in the machine cycle in the cutting and edge sealing station 7.
  • the cutter 20 is moved by the lifting device 23 from the first position shown in Fig. 3 in the second position shown in Fig. 4, whereby the path of the moldable sheet material 3 respectively outside the outer contour of a shell 1 around by the cutting blade 22nd is severed, so that a lateral edge 3a of the sheet-like material 3 outside the peripheral upper edge 13 of each shell 1 is formed.
  • the sealing tool 31 of the edge sealing device 30 is moved by means of the lifting device 32 from the first position shown in FIG. 4 into the second position shown in FIG. 5.
  • the lateral edge 3a of the moldable sheet material 3 is pressed by the circumferential projecting edge 33 of the sealing tool 31 along the entire contour of the peripheral upper edge 13 of the shell 1 in an upper portion 14a against the outer side edge 14 of the shell 1, as Best seen in the enlarged detail view in Fig. 6.
  • the encircling projecting edge 33 of the sealing tool 31 is heated and there is a thermal sealing of the lateral edge 3a of the moldable sheet material 3 to the outer side edge 14 of the shell 1.
  • the peripheral projecting edge 33 presses the lateral edge 3a of the web-shaped material. 3 against the upper portion 14a.
  • the circumferential projecting edge 33 is therefore in contact with the upper section 14a via the formable sheet-like material 3.
  • the inner wall 34 of the peripheral projecting edge 33 ensures that the lateral edge 3a of the web-shaped Material 3 is reliably pressed against the outer side edge 14 of the shell 1.
  • the beveled surface 35 allows easy passing over the peripheral edge 13 of the shell 1 by the circumferential projecting edge 33, even if the shell 1 is not optimally located in the tray receiving position A.
  • the cutting and edge sealing station 7 thus has three lifting devices, for opening and closing the entire station, for the movement of the cutting device 20 and for the movement of the edge sealer 30. These may e.g. all be realized via piston-cylinder devices.
  • the packaging thus produced can then be filled in a filling station, not shown, with the goods to be packaged and then sealed in a sealing station, also not shown with a second web-shaped material along the peripheral upper edge 13. It may also be provided an Evakuier thanks in which the atmosphere in the package is evacuated and replaced by a replacement gas. In particular, an exchange by a protective gas, such as CO 2 , in question, which prevents aging of the packaged goods or delayed.
  • a protective gas such as CO 2
  • the trays 1 and the formable sheet material 3 are transported from one workstation to the next in a clockwise cycle in a main machine cycle, and the edge is cut and sealed in the cutting and edge sealing station 7 in one clock cycle.
  • the trays 1 are processed with the trough 10 directed downwards and the cutting knives 22 and the tucking tool 31 are located below the path of the formable sheet material 3, the reverse arrangement is also possible.
  • sealing of the overhanging edge 3a of the moldable sheet material by heat is described, however, another form of sealing is possible, such as e.g. a sticking.
  • the packaging is not limited to the form described, there are many different packaging forms depending on the product to be packaged conceivable. Also, the package is not limited to the foamed polystyrene described in the above embodiment, but various materials that require such a coating are conceivable.
  • the cutting device 20 and the edge sealing device 30 are integrated in a cutting and edge sealing station 7, but it is also a separate training possible. Then, however, the packages must be re-grasped after cutting and before the edge is sealed, and processing in the cutter 20 and the edge sealer 30 occurs in mutually different clock cycles.
