Definitions

  • the invention relates to a method for sealing trays with film, comprising sealing the film to the tray edges and separating the trays by cutting the film.
  • the invention further relates to a device for sealing trays with film, comprising a holding receptacle for the trays, a sealing tool arranged above the trays, and a holding tool for the film, which is arranged between retaining receptacle and sealing tool, preferably for carrying out the aforementioned method.
  • Methods of sealing shells with foil are known. With these, for example, food or objects are packaged, this is an object placed in the shell, then the shell is sealed with foil.
  • various films may serve, for example, top films, which remain approximately in the plane of the peripheral shell edge, or deep-drawing films, which closely abut the inserted into the shell object, so that in the region of the packaged object only a small Residual volume of an atmosphere remains.
  • Trays can reach a greater extent, for example, when larger pieces of meat are to be packaged.
  • a correspondingly large film section is needed, which is jossiegeln on the peripheral edges. If this film is too deep to pull, make sure that the film is heated.
  • the invention is therefore based on the object to provide a method of the type mentioned, with the deep-drawing film in particular can be successfully sealed even with large shells. Furthermore, a device for sealing trays is to be shown, with which in particular the aforementioned method is feasible.
  • this object is achieved in that the film is first fixed to a sealing tool arranged above that the film is acted upon by the sealing tool with heated gas, then that the film is guided against the sealing tool and then sealed onto the shell edges becomes.
  • this film is fixed to the above-arranged sealing tool, so that an action on the film does not lead to their displacement or slippage.
  • the next measure is to pressurize the film with heated gas, for example heated compressed air.
  • heated gas for example heated compressed air.
  • This gas is passed through the sealing tool, it can thereby approach the film at different locations.
  • the heated gas With the heated gas, the film is heated, at the same time it is carried away with the gas from the sealing tool. It can assume a bulbous shape, it is suitably vorgereckt and lengthened.
  • the foil is guided against the sealing tool, which means that the supply of heated gas ceases and optionally this heated gas is withdrawn by applying a vacuum again.
  • the film can also be guided from the other side against the sealing tool, here a compressed air can be used.
  • the sealing tool is warm, the film attaches itself to the sealing tool and is thereby further heated. In this condition, it is then sealed onto the shell edges.
  • the gas is, for example, passed against the film at a low pressure of 0.2 to 0.5 bar, which ensures that no areas are formed in which the film has a thinner thickness than in other areas.
  • the gas is supplied in this process step over the surface of the film about evenly distributed.
  • all areas of the film are heated in the same way, in the same way they are also lifted from the sealing tool and elongated or stretched.
  • the film is preferably cut after sealing on the shell edges.
  • the cutting takes place so that the shell edges are not to be damaged.
  • This cutting also has the advantage that clean cut edges of the sealed film are formed.
  • the cut edges are straight and not frayed.
  • the cut edges are also firmly connected to the shell edge, so that they have a flat, high-quality appearance.
  • the device-side solution of the problem is characterized in that at least in a component of the sealing tool, a plurality of gas channels is arranged, which open into a contact surface for the film in the sealing tool.
  • a component of the sealing tool according to the invention is equipped with gas channels.
  • These gas channels are available in a variety, they can be guided by gas.
  • the gas guide is possible in both directions.
  • the gas channels open into a contact surface for the film in the sealing tool, so gas can be brought to the film through the gas channels, for example, to lift them from the sealing tool to heat and vorzuscken, or it can gas from the area between contact surface and film on the gas channels are removed, so that the film is used on the contact surface.
  • the preparatory measures of the film according to the method of the invention are thus feasible with a sealing tool designed in this way.
  • This holding tool is preferably a spacer plate with openings for the sealing tool.
  • the spacer plate can components of the sealing tool, such as holding devices for cutting tools or similar at a distance to the holding receptacle for the shell hold, but the sealing tool can overcome this distance, since in the spacer plate an opening for the sealing tool is provided.
  • the spacer plate is durable on the sealing tool, so that it is associated with this correct position.
  • the component with the gas channels has on its side facing the film, the contact surface for the film, while this contact surface preferably has a dome-like design.
  • the film may lengthen due to the dome-like design, the film is thereby pulled over a voltage applied to the gas channels vacuum against the contact surface.
  • the gas channels are at least partially aligned parallel to each other, it can be set at gas channel sections and special angular relationships.
  • a knife for cutting the film is preferably applied pneumatically, so that can be performed very accurately and it is achievable that only the optionally already sealed foil is cut, but not the shell edge.
  • the device according to the invention for sealing trays 1 has a holding receptacle 2, a sealing tool 3 and a holding tool 4 arranged between holding receptacle 2 and sealing tool 3 for a foil 5.
  • a holding receptacle 2 In the shell 1, an object 6 to be packaged is received.
  • the film is 5. This is to be sealed onto the peripheral edge 7 of the shell 1.
  • the sealing tool 3 has a heatable component 8, which has sealing end regions 9, which can be placed on the peripheral edge 7. These end regions 9 are also associated with blades 10.
  • FIG. 2 the first step is shown, namely the setting of the film 5 on the sealing tool 3.
  • This setting is done with the holding tool 4, which is designed as a spacer plate and which has an opening 11 for the component 8 of the sealing tool 3.
  • FIGS. 1 to 3 It is clear that in the component 8 of the sealing tool 3, a plurality of gas channels 12 are arranged. Through these gas channels is in FIG. 3 Added via a central supply 14 warm compressed air, which exits along the arrows 13 from the gas channels 12. The supply takes place here evenly, resulting in an increase in volume of the gap between the film 4 and component 8. The film 4 is heated, it is softer, it can be deflected like a bulb. In this state, the film 5 is fixed by the holding tool 4.
  • FIG. 4 If the feed 14 is now an exhaust, arrows 15 show that the gap between the component 8 and the film 5 is evacuated. The film 5 lays tight against a contact surface 16 of the component 8. In FIG. 5 is then the holding receptacle 2 has been performed up against the holding tool 4. Fig. 5a shows that the holding receptacle 2 and the sealing tool 3 are vented at this time, arrows 15a.
  • the component 8 of the sealing tool 3 is in FIG. 6 placed on the peripheral edge 7 of the shell 1. Now it is sealed.
  • FIG. 7 the knives 10 are lowered, so that now the film 5 is cut on the peripheral edge 7.
  • the cutting of the film 5 takes place on the peripheral edge 7.
  • the cut areas of the film 5 are thereby with clean edge closely on the peripheral edge 7, such as Fig. 9 shows.
  • the design of the peripheral edge with an angled free end is not separated from the shell 1, it remains.
  • FIG. 9 shows the shell 1 with inserted product 6 after demolding. Remains of the film 5, which are disposed of. The shell 1 is taken out of the holding receptacle 2, in this can subsequently a new, empty shell 1 are inserted.
  • FIGS. 10a to 10c In the first embodiment in FIGS. 10a to 10c is in perspective view in FIG. 10a the component 8 is shown. In the contact surface 16 open the gas channels 12, these are arranged here in the center of the contact surface 16.
  • FIG. 10b shows that a supply of compressed air through the feed channel 14 then takes place through the gas channels 12 only in the center of the component 8.
  • the film 5 is thus heated in the center of their extension, they can then invest well on a survey 18 in the article 6, as FIG. 10c after demolding shows.
  • the gas channels 12 are arranged on the edge of the contact surface 16.
  • FIG. 11b shows that the object 6 has elevations 18 in these areas.
