Definitions

  • the invention relates to a device for packaging goods by means of a shrink film with a conveyor track for transporting the goods to a station for wrapping them with thermoplastic films and further through a heatable channel in which the films can be shrunk onto the goods, in the station
  • a roller of a pair of rollers with thermoplastic foil belts and a device for separating the strip pulled from each roller and for welding the strips pulled off the two rollers are provided.
  • the free ends of the film strips drawn off from the rollers arranged on both sides of the conveyor track are welded to one another, thereby forming a curtain located transversely to the conveyor track.
  • a good that is to be packaged along the conveyor track, its end face runs onto this film curtain and, during the further movement of the good, lies on the side surfaces of the film.
  • the device for welding and separating the film strips is then put into operation, by means of which the two film strips are also placed on the back of the goods and connected to one another by means of a double weld seam. The film strips are separated between the double weld seam.
  • the double weld seam on the one hand connects the film strips pulled off by the two rollers to the back of the goods to be packaged, and on the other hand they are joined together to form the film curtain required for packaging a subsequent good.
  • the packaging on the underside or on the top of the goods takes place in that the pallets for holding the Goods, before the respective good is applied to them, a foil sheet is placed on top of it, and that another foil sheet is placed on top of the good. These two foil sheets are welded to one another in the shrink channel with the foil strips through which the goods were encased.
  • the object of the invention is to create a device which ensures that goods of different heights are properly packaged without the need for additional work.
  • This is achieved according to the invention in that a plurality of roller pairs are provided with film strips of different widths, one roller pair each being adjustable from the side of the conveyor track or from above into its operating position on the conveyor track.
  • the height of the goods to be packed is scanned by means of a measuring device arranged in front of the film rollers in the area of the conveyor track, whereupon a transport device for adjusting the pairs of rollers is scanned Signal is emitted by which that pair of rollers, the film width of which has a value which is adapted to the height of the goods to be packaged, is adjusted to its operating position on the conveyor track.
  • roller pairs can be adjusted either from the side of the conveyor track or from above into their operating position. After covering the goods in question with the film, either the roller pair remains in its operating position, provided that the subsequent material has approximately the same size, or the roller pair in question is moved out of the area of the conveyor track again by means of a subsequent control signal and another roller pair is included in this area Foils that have a smaller or larger width are adjusted.
  • the pairs of rollers can be arranged on carriages or carriers which can be adjusted along longitudinal guides, a device associated with the relevant pair of rollers for separating and welding the strips pulled off from the two rollers being also provided on the carriages or carriers. These slides or carriers are moved into the region of the conveyor track in planes one behind the other in the conveying direction.
  • the individual roller pairs can be assigned a single device for cutting and welding the film strips, the roller pairs being adjusted in different planes in the area of the conveyor track, but furthermore the film strips by means of separate tensioning and guiding devices assigned to the individual roller pairs be guided in an area which is located close to the adjustment plane of the bars of the device for welding and cutting the film strips.
  • a device As shown in Fig. 1, a device according to the application consists of a conveyor track 1, by means of which goods to be packed, e.g. Goods stacked on pallets: cartons containing, a device for wrapping by means of thermoplastic film tapes and then a device for heating these films, whereby they are shrunk onto the goods.
  • goods to be packed e.g. Goods stacked on pallets: cartons containing, a device for wrapping by means of thermoplastic film tapes and then a device for heating these films, whereby they are shrunk onto the goods.
  • first station 2 the goods 10 are aligned for the wrapping process.
  • second station 3 the goods 10 are wrapped by means of the film strips.
  • This station 3 has a frame-like frame 31 in which three slides 32a, 32b, 32c can be displaced transversely to the conveyor track 1.
  • a pair of rollers 33a, 33b, 33c are each carried by the slides 32, 32b, 32c with a thermoplastic film strip 34a, 34b, 34c and two beams of a cutting and welding device 35a, 35b, 35c.
  • the individual carriages 32 can be adjusted in planes lying one behind the other transversely to the conveying direction, which is indicated by the arrow A. They differ from each other only in that 33 rolls of film with different widths can be pulled off the rollers.
  • a first film band 34a can have a width of approximately 2 m
  • a second film band 34b can have a width of approximately 1.50 m
  • a third film band 34c can have a width of approximately 1 m.
  • the height of the good 10 that is to be enveloped by film strips 34 is scanned in each case. From this measuring device, a signal is emitted to the wrapping station 3, by means of which the carriage 32, the film rollers 33 of which have the film strips 34 with the corresponding width, is adjusted into its working position. As soon as the material 10 in question enters the wrapping station 3, it is wrapped in a known manner by the film strips 34. Thereupon, these are welded to one another by means of the bars of the welding and separating device 35, or the individual foil strips 34 are separated. After a subsequent measurement signal has been received, the respective slide 32 remains in its working position or is moved out of it and another slide 32 is included Foil tapes 34 of different widths adjusted into the working position.
  • the exemplary embodiment according to FIGS. 2 and 3 differs from the exemplary embodiment according to FIG. 1 in that the rollers 33a, 33b, 33c for the film strips 34 are held by carriers which are guided into their working position above the conveyor track 1 from above by guides 36 can be lowered.
  • tensioning or guiding rollers 38 are assigned to the foil strips 34 pulled off from the individual roller pairs 33, through which the curtains formed by the foil strips 34 and spanning the conveying path 1 transversely extend approximately in one plane assigned, which is formed by two welding bars 7, 8 which are adjustable transversely to the conveying direction A.
  • the operation of this device corresponds to the operation of the device according to FIG. 1, apart from the fact that the pairs 33 of the rollers with the film strips 34 are not adjusted into their working position from the side of the conveyor track, but that they are guided along the guides 36 into their working position from above be lowered.
  • FIG. 4 of the drawing the device according to FIG. 1 is shown axonometrically.
  • a film dispenser 40 is also shown, by means of which a cover film is applied to the cover surfaces of the goods 10 that are to be packaged, which cover film is pulled off a roller 45 and divided into individual sheets by means of a separating device 46 .
  • the goods 10 After the goods 10 have been wrapped with the foils, they are conveyed in a known manner to a subsequent third station, which is formed by a shrinkage channel in which the foil strips, depending on their thickness, are heated to 180 ° C. to 260 ° C. and higher temperatures and thereby to the goods are shrunk.
  • a subsequent third station which is formed by a shrinkage channel in which the foil strips, depending on their thickness, are heated to 180 ° C. to 260 ° C. and higher temperatures and thereby to the goods are shrunk.
