Definitions

  • the invention relates to a device for packing a stack of goods held in particular by a pallet by means of a shrink film with a conveyor track for transporting the stack of goods to a station for wrapping them with foils made of thermoplastic material and further for transporting the stack of goods through a heatable channel in which the Films are shrink-fit onto the stack of goods, in the station for wrapping the stack of goods with the films several pairs of rollers with film strips of different widths, which pairs can be moved transversely to the conveying direction into and out of the working position, and further a device for separating the the two rolls of the pairs of peeled films and for welding them together 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 extending 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 connected to form the film curtain required for the packaging of a subsequent good.
  • the packaging on the underside or on the top of the goods takes place in that a foil sheet is placed on the pallets for holding the goods before the respective goods are applied to them, and that another foil sheet is placed on the top of the goods becomes. These two foil sheets are welded to one another in the shrink channel with the foil strips from which the goods were enveloped.
  • FR-PS 2 276 224 discloses a device which is formed with two rollers of a pair which are located above and below the conveyor track. Basically, the foils on these two rollers work together as explained above. However, by means of this known device, the undersides of the pallets carrying the stack of goods are also covered with foils, which should also be avoided.
  • This known device also contains two pairs of rollers with film strips of different widths, the pair with the required width of the film being brought into the working position.
  • these two pairs of rollers are in the same plane, it is necessary to adjust the pair of rollers that are in the working position in their rest position, after which the other pair of rollers can only be brought into the working position.
  • one pair of rollers is moved into its working position and removed when a different width of film is required, whereupon the other pair of rollers is brought into the working position.
  • An expansion of this device to an enlarged number of pairs of rollers is therefore not possible, since this would require complicated movements of the pairs of rollers.
  • the invention is therefore based on the object of avoiding the disadvantages inherent in this known device.
  • This is achieved according to the invention in that the individual pairs of rollers, which are at least approximately vertically aligned, can be moved into their working position in planes that are spaced apart in the direction of the conveyor path from above the conveyor path or in a manner known per se . In this way, regardless of the number of pairs of rollers, one can be adjusted from its working position to its rest position without these adjustment movements hindering one another. Since an arbitrary number of pairs of rollers can be provided as a result, a significant improvement in the mode of operation of the device is achieved, since an arbitrary number of film strips of different widths can be used.
  • the individual roller pairs and a welding and cutting device assigned to each of them are on separate carriages, which run along guides from one side of the conveyor track into their working position, in each of which a roller is located to the side of the conveyor track det, can be inserted.
  • the individual pairs of rollers and a welding and separating device assigned to them are arranged on separate supports, which can be lowered along guides from above into their working position, in each of which a roller is located to the side of the conveyor track.
  • the individual pairs of rollers and the tensioning devices assigned to them are arranged on separate supports which can be lowered from above into the working position of the rollers, all of the roller pairs being assigned only a single welding and cutting device.
  • a device As shown in Fig. 1, there is a device according to the application consisting of a conveyor 1, by means of which goods to be packed, e.g. Cartons stacked on pallets containing goods, a device for wrapping by means of thermoplastic film strips and then a device for heating these films, whereby they are shrunk onto the goods.
  • a first station 2 the goods 10 are aligned for the wrapping process.
  • the goods 10 are wrapped in a second station 3 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 32a, 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 are adjustable 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 the rollers have 33 foil strips with different widths.
  • the first film band 34a can thus have a width of approximately 2 m
  • the second film band 34b can have a width of approximately 1.50 m
  • the third film band 34c can have a width of approximately 1 m.
  • the height of the good 10 is to be scanned, which is to be wrapped next with foil strips 34.
  • a signal is emitted to the wrapping station 3, by means of which the carriage 32, the rollers 33 of which have the film strips 34 with the corresponding width, is adjusted into its working position.
  • the material 10 in question enters the wrapping station 3, it is wrapped in a known manner by the film strips 34.
  • 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.
  • the carriage 32 in question remains in its working position or is moved out of it and becomes another carriage 32 with it 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 guide rollers 38 are assigned to the foil strips 34 drawn off from the individual roller pairs 33, by means of which the curtains formed by the foil strips 34 and spanning the conveying path 1 transversely are held in closely adjacent planes.
  • These curtains are assigned a single, frame-fixed separating or welding device, which is formed by two welding bars 7, 8 which are adjustable transversely to the conveying direction.
  • 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 from the side of the conveyor track in their working position, but that these from above along the guides 36 in their Working position can be lowered.
  • FIG. 4 of the drawing the device according to Figure 1 is shown axonometrically.
  • a film dispenser 40 is also shown, through 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 the individual sheets by means of a separating device 46 becomes.
  • 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 are heated to 180 ° C. to 260 ° C. and higher temperatures, depending on their thickness, whereby they are shrunk onto the goods.
  • a subsequent third station which is formed by a shrinkage channel in which the foil strips are heated to 180 ° C. to 260 ° C. and higher temperatures, depending on their thickness, whereby they are shrunk onto the goods.
