Definitions

  • the present invention relates to a shrinking device for shrinking an outer package around an article assembly.
  • the shrinking device comprises a transport path, an entrance area, a shrink tunnel and an outlet area, wherein in the exit area above the transport path at least one first coolant device is arranged, through which the article assembly can be acted upon from above with coolant.
  • the articles When packaging articles, in particular beverage containers, bottles, etc., into containers, the articles are assembled in the desired manner and covered with a shrink film.
  • the shrink wrap is shrunk around the articles by supplying hot air in a shrink tunnel.
  • the containers are transported on a conveyor through the shrink tunnel. Due to the permanent supply of hot air, the conveyor chain heats up. This can lead to problems because due to excessive local heating shrink film stuck in the bottom of the container with the conveyor and thus can lead to damage to the shrink wrap. For this reason, devices are known in which the conveying device is selectively cooled.
  • shrink packs After the shrink packs leave the shrink tunnel, they must cool relatively quickly, before you or other processing devices, such as palletizers. be supplied.
  • the shrink film itself has a so-called memory effect.
  • the film material used is heated, while stretched and then cooled again.
  • the shrink wrap wrapped around the articles is reheated.
  • the shrink film changes back to its unstretched original state, with the molecules rearranging themselves in their original form.
  • the shrinking process thus consists of heating and cooling the shrink wrap wrapped around the packs.
  • a shrinkage package is stable only when the shrink film has cooled so far after heating, that no further deformation (contraction of the shrink film) takes place more and the shrinkage package is thus firm and stable.
  • Such unfavorable forces additionally act against the still unfinished shrinking process when the shrinkage package is still warm or not yet fully cooled and thus worsen the result or lead to defective packaging.
  • Such unfavorable forces acting on the shrinkage packages can be found, for example, at transitions between individual conveyor belts following the shrink tunnel, via which the shrinkage packages are fed to further processing devices. This is due to not yet completely cooled shrink film in the bottom area of the container easy to damage the same. In this bottom area where the shrink film ends overlap, the time to complete cooling is higher than in the other areas (top, front of the container, etc.). Upon cooling of the shrink film, the film contracts further and is firmly fixed around the wrapped articles.
  • This necessary cooling of the container can be achieved for example by the fact that after the shrink tunnel, a so-called cooling line is present. This is often extended due to the given ambient temperatures or due to the thickness of the film used to ensure that the shrinkage packages are cooled sufficiently before they are passed to the next conveyor belt.
  • the conveyor, with which the shrinkage packages are moved through the shrink tunnel and through the cooling section, is a single conveyor line whose length is designed according to the respective requirements. Optionally, an adaptation of the conveyor line is therefore necessary in a product change.
  • one or more fans are installed after the shrink tunnel above the conveying means. used to blow the cooling air from above onto the product.
  • the bottom of the container is not covered by this cooling air, so that there is less cooling of the container in this area.
  • the containers in this area have a lower stability, which is particularly in the transfer to a downstream conveyor belt, a container turning station o.ä. leads to problems.
  • This problem is generally solved by the combination of blowers mounted in series and an extension of the cooling line and the type mentioned at the exit of the shrink tunnel.
  • An extension of the cooling section is very complex, since this - as already described above - brings with it an extension of the entire conveyor.
  • US 3727324 describes a shrink tunnel that provides an air curtain at the entrance and the exit, respectively.
  • the first air curtain at the entrance to the shrink tunnel serves to preheat the film in this area.
  • the second air curtain at the exit of the shrink tunnel serves to cool the film in the exit area.
  • a cooling arc is arranged at the outlet of the shrink tunnel through which cooling air is blown from above and from the sides onto the shrink-wrapped pallet with piece goods.
  • DE 2320424 A1 describes an apparatus for the continuous packaging of articles comprising a shrink tunnel. Cooling of the packaged articles also takes place after the shrinking process, whereby a cooling arrangement arranged at the top directs cold air onto the enveloped objects, thereby accelerating the cooling of the articles and their shrunk-on packaging.
  • WO 03/093114 A1 describes a method for producing a packaging unit.
  • the packaged goods are transported on a conveyor belt of individual air-permeable chain links and, after the shrinking station, pass through a cooling station in which the packaging units are cooled in a controlled manner via corresponding cold nozzles.
  • FR 2588828 describes a shrink tunnel. Simultaneously with the hot shrinkage air, a gaseous fluid of lower temperature is injected between the shrink wrap and the article. This takes place within the shrink tunnel, for example via suitable means. It can be provided that the device with the cooling gas accompanies the article during movement on the conveyor. This effectively prevents local overheating during shrinkage.
  • DE 1586349 also discloses a shrinking device.
  • the conveyor belt In a subsequent to the shrink tunnel area, the conveyor belt is cooled from below.
  • the object of the invention is to containers in the output area of a Cooling shrink tunnels effectively and on all sides while preventing shrinkage air from escaping from the shrink tunnel.
  • the invention relates to a shrinking device for shrinking an outer package or a shrink film around an article compilation.
  • the articles are preferably liquid containers, in particular beverage bottles, which are wrapped with a shrink film and combined into containers.
  • the shrinking device comprises a transport path, via which the containers are transported in the transport direction via an input area into a shrink tunnel and via an exit area to further transport devices or other processing devices.
  • at least one first coolant device is arranged above the transport path, by means of which the containers are subjected to a coolant from above.
  • Preferably above the transport route at least one blower o.ä. arranged, with the cold air on the coming out of the shrink tunnel, warm container is blown.
  • the transport path consists of a continuous, uninterrupted transport means, i. from a single conveyor belt or similar, on which the containers are transported through the entrance area, the shrink tunnel and the exit area to a transfer area.
  • the finished shrunk containers are transferred to another means of transport or to a further processing device.
  • the transport of the shrinking device is permeable to a coolant.
  • at least one second coolant device is arranged below the transport means, by means of which coolant is applied to the bottom region of the bundles from below. Due to the additional coolant device, the bottom portion of the container can be cooled specifically. This was with the previous cooling from above insufficient or not at all possible. Due to the cooling from below, the front sides and side surfaces of the lower regions of the containers are now subjected to more coolant, since the distance from the surface to be cooled to the coolant device is now substantially lower.
  • At least one upper and one lower coolant device are arranged directly opposite each other directly at the exit from the shrink tunnel.
  • the upper coolant device produces a largely vertically downwardly directed coolant flow.
  • the lower coolant device produces a largely vertically upward coolant flow.
  • the two coolant streams thus form at the exit of the shrink tunnel a coolant curtain, in particular an air curtain. This prevents the hot air from escaping uncontrolled from the shrink tunnel and thus has a positive effect on the energy balance of the shrinking device.
  • the transport means is preferably a conveyor belt, in particular an endless conveyor chain, a wire belt, a mesh grid belt, a Stabröllchenkette or similar suitable conveying means which is permeable to a flow of coolant.
  • a coolant in particular, a cooling air flow is used, which is provided by at least one fan, a fan, for example a cross-flow fan, a radial fan or an axial fan or the like. is produced.

  • the blower can also be arranged outside the shrinking device and the cooling air can be conducted via lines to the desired locations.
  • a cooling channel can be arranged below the transport path. The coolant is directed into the cooling channel and the container bottoms are supplied with coolant via nozzles pointing upwards.
  • the nozzles are adjustable, in particular, an adjustability of the nozzle angle and the size of the nozzle opening can be provided, so that the amount and angle at which the coolant impinges on the container bottom, can be adjusted.
  • the coolant is preferably blown at an angle between 30 ° to 150 ° to the transport surface from below to the bottom of the container.
  • the air sucked in by the fan is taken, for example, from the area of the machine frame below the conveyor belt. Alternatively, the air may also be removed via side intake ducts from the environment or from another packaging device.
