Definitions

  • the invention relates to a method for shrinking a shrink film on packaging according to the preamble of patent claim 1.
  • Packaging especially in the form of containers, which consist of several packaging units and are held together with a shrink film, are known in various designs. Packing units are for example filled with a product and closed packaging, such as. Bottles, cans, but also filled with a product packaging of a single or multi-layer sheet, etc.
  • a plurality of packaging units each are assembled into a bundle group, then wrapped with the shrink film and this under application of at least one jet of hot gaseous medium, i. Shrunk in practice with hot air to the package group that the packaging units are connected to the container together.
  • the shrinking of the shrink film is carried out by moving the packaging or container on a conveyor through an example designed as a shrink tunnel device.
  • the currently common technique does not succeed in all cases when shrinking the shrink wrap wrinkle-free packaging to produce, as this is increasingly required to meet the increased demands of customers.
  • a method is known according to the preamble of claim 1 for shrinking shrink films on packaging ( US 5,787,682 A1 ), in which are provided below a transport path for the packaging, nozzle assemblies for emitting a jet of hot gaseous medium, for example, the delivery of hot air.
  • the nozzles and thus also the jet of hot gaseous medium emerging from them are moved with the respective packaging during the shrinking of the shrink film.
  • the nozzles are controlled so that only the leading and trailing in the transport direction, oriented transversely to the transport direction ends of the packages are subjected to the hot gaseous medium.
  • the disadvantage here is, inter alia, that the rays emerging from the nozzle openings are cut by the Schrumpfffolienkanten or supernatants surrounding the shrinkage, resulting in an arbitrary folding or folding these edges during shrinkage and thus to an optically unacceptable appearance of the respective container after shrinking Shrink film leads.
  • the at least one jet of the hot gaseous medium is moved with the respective packaging in such a way that this jet is directed exclusively to the shrinkage eye during the shrinking process.
  • This is produced by the fact that when wrapping the package with the shrink film at least one example lateral opening remains as shrinkage eye, then enters through the hot, gaseous medium with the at least one beam in the surrounding the packaging and formed by the shrink wrap shell and thereby a Shrink the shrink film from the inside out.
  • the at least one jet is moved in such a controlled manner with the packaging that it hits the shrinkage eye as centrally as possible, but in no case shrink film overhangs or shrink film edges or edges cut or break this beam.
  • the controlled entrainment of the at least one jet of the hot gaseous medium with the respective packaging can be realized in many different ways, for example by moving at least one nozzle opening for discharging the hot gaseous medium with the respective packaging, or else by moving it along the transport path, on which the package is moved when shrinking the shrink film, at least one nozzle arrangement is provided with a plurality of controlled exit or nozzle openings for the hot gaseous medium.
  • the nozzle openings are activated and deactivated in computer-controlled or computer-controlled manner, for example, so that only one or more nozzle openings are activated for the delivery of the jet of hot gaseous medium, where a package is also located on the transport route, so that the at least an activated nozzle opening emerging jet of hot gaseous medium in the shrinkage eye of the respective packaging meets.
  • the activation and deactivation of the nozzle openings takes place, for example, by means of controlled slides or shutters. In principle, it is also possible to provide a plurality of nozzle nozzles forming individually controllable nozzles.
  • 1 container each consisting of a plurality of packaging units 2, namely in the illustrated embodiment of a total of six packaging units designed as bottles, from a carrier 3 for these packaging units and from a shrunk onto the packaging units 2 and the carrier 3 and thus the container 1 cohesive packaging or shrink film 4 exist. Because of the simpler presentation are in the FIG. 1 the packaging units 2 of the container 1 in total as a volume 2.1.
  • the shrink film 4 is wrapped in each case in a device, not shown, but known in the art about the unit formed by the packaging units 2 and the carrier unit 3, so that the shrink film 4 each container 1 above and below encloses the respective container. 1 but at two opposite sides initially open and characterized each case a so-called shrinkage eye 5 is formed, which is surrounded by a film projection 4.1.
  • a so-called shrinkage eye 5 is formed, which is surrounded by a film projection 4.1.
  • the shrinking of the shrink film 4 is carried out using lateral hot air jets A, which are each directed to a shrinkage eye 5. Due to the dynamic pressure occurring in this case, the shrink film 4 is slightly lifted off the packaging units 2 and also laterally from the carrier 3, e.g. about 20 - 30 mm. This will u.a. ensures that the energy input is made by the hot air to the inside of the shrink film 4, for an optimal shrinking of this film on the container 1. To achieve a wrinkle-free shrinking of the shrink film 4, it is essential that the respective hot air flow A from the side is as accurately as possible directed to the center of the shrinkage eye 5 and not on the shrinkage eye 5 surrounding edges or film overhangs 4.1.
  • the sealing of the shrink film 4 at the bottom of the container 1 and the carrier 3 is carried out using directed to this bottom hot air jets, as shown in the FIG. 1 indicated by the arrows B.
  • the device 6 is designed as a shrink tunnel through which the containers 1 provided with the shrink film 4 are moved, in each case on a conveyor belt 7 in a horizontal transport direction C.
  • the device 6 is two lanes with two parallel Conveyor belts 7 formed.
  • Each nozzle arrangement consists in the illustrated embodiment of a in the transport direction C extending closed distribution channel 10, which is connected to a hot air supply, not shown, and extends in the vertical direction over a height which is at least equal to the maximum height of the device to be processed with the container 6 1 is.
  • the outer nozzle assemblies 8 have on the respective conveyor belt 7 facing, arranged in a vertical plane and extending in the transport direction C side of the distribution channel 10, a plurality of outlet or nozzle openings 11 for hot air.
  • the distribution channel 10 of the nozzle assembly 9 has these nozzle openings 11 at both, each arranged in vertical planes and extending in the transport direction C sides.
  • the outlet openings 11 are each distributed so that they form a plurality of vertical rows R1 - Rn, in which the nozzle openings 11 close to each other and which are provided in close succession in the vertical direction.
  • Each row R1 - Rn or each of a group of two or more than two rows is associated with a slide 12, which can be controlled by a stand-alone actuator, for example in the form of a pneumatic cylinder, so moved that the nozzle openings 11 in a state of the slider 12 closed by this and are open in another state of the slider.
  • a stand-alone actuator for example in the form of a pneumatic cylinder
  • control electronics for example via a computer
  • the control of the slide 12 takes place, for example, by means of sensors which deliver a signal corresponding to the respective position of the containers 1, and / or taking into account the transport speed of the conveyor belts 7 likewise determined by sensors.
  • containers 1 of different heights are also to be processed with the device 6, means are provided for adapting the height of the rows R1-Rn effective at the respective shrinking process to the height of the containers 1.
  • This is for example possible because in addition to the slides 12 further, for example, horizontally moving slide 13 are provided with which then a certain number of the nozzle openings 11 of each row R1 - Rn can be switched to be effective or ineffective.
  • each nozzle opening is formed on an individually controllable hot air nozzle, so then computer-controlled these individual nozzles are opened and closed, in turn so that the side of the container 1 or their shrinkage eyes 5 move directed hot air jets A with the containers 1 in the transport direction C and the number and position of the respective activated nozzles of the position and shape and / or size of the container 1, or correspond to the shrunken eyes formed on these containers.
  • FIG. 5 shows a schematic representation of a device 6a, in which the shrinking of the shrink film 4 takes place on the container 1 in a carousel system 14 on which the container 1 when shrinking the shrink film 4 on a vertical machine axis enclosing circular path are moved (arrow D).
  • Shrink bells 15 are provided above the carousel system 14 or above a standing surface formed by this carousel system for the containers 1, which are moved together with the containers 1 on or in the carousel system 14 and which in each case have a hose or pipe connection 16 with a center the carousel system 14 arranged hot air supply 17 are connected.
  • the shrink bells 15 are, for example, according to the FIG. 6 formed, ie they consist of a frame 18, are formed at which nozzle openings 19 for the exit of the hot air jets A so that the exiting hot air jets A are directed in the illustrated embodiment in an axial direction radially to the vertical machine axis or to the axis of rotation of the carousel system 14, namely radially outward or radially inward.
  • the containers 1 provided with the shrink film 4 are fed to the device 6a via a conveyor 20 in such a manner that each container 1 is arranged on the carousel system 14 under a shrinking bell 15 and the shrinking eyes 5 lie radially outside or radially inward relative to the axis of rotation of the carousel system 14 , Due to the fact that the shrinking bells 15 move with the carousel system 14 and the containers 1 arranged thereon, it is ensured that the shrinking eyes 5 are in each case blown centrally with the hot air jets A during shrinking. After shrinking the shrink film 4, the container 1 are lowered on the carousel system 14 and then get lowered or submerged on the conveyor 21 for removal.
  • FIGS. 7 and 8th show as another embodiment, a device 6b, in which the shrinking of the shrink film 4 on the container 1 in turn when moving these containers on a circular path about a vertical machine axis using a carousel system 22 takes place.
  • the device 6b differs from the device 6a of Figures 5 and 6 in that there are no shrinking bells moved along with the carousel system 22, but a nozzle arrangement 23 or 24 is respectively provided inside and outside on the circular transport path formed by the carousel system 22. These are formed, for example, according to the nozzle assemblies 8 and 9, but partially curved curved.

  • Sliders corresponding to sliders 13 are again a format adaptation, i. an adaptation to the height of the container 1 possible.
  • the nozzle openings 11 can also be formed in each case by individually controllable individual or Schubuchdüsen, which are then controlled for the required Mitbe admire the hot air jets A synchronously with the movement of the container 1 on the carousel system 22, for example, again taking into account sensor signals, the Define the position of the containers 1 on the carousel system 22.
  • the containers 1 are lowered and then arrive in the lowered state on the conveyor 21st
  • FIGS. 9 and 10 show a device 6c, in which the container 1 for shrinking the shrink film 4 are moved on a transport path 26 formed by a paternoster 25 system.
  • the containers 1 are fed to the device 6c via the feed dog 20 and transported away after shrinking the shrink film 4 from the device 6c via the feed dog 21.
  • the containers 1 are each moved on a container support 27 initially on a section 26.1 of the transport path 26 in the vertical direction upwards (arrow E) and then continue on the container support 27 standing with this on the section 26.2 of the transport path 26 in vertical Direction down (arrow F) to the output of the device 6 c moves.
