Definitions

  • the invention relates to a device for packaging, in particular quadrangular objects, such as books, catalogs, magazines or the like, by means of a film, the film being guided over the article by guide devices, with connecting devices in and transversely to the direction of travel of the articles, the articles are offset laterally to the width of the film web to essentially only half the width of the film.
  • Devices of this type are used in particular to pack cuboid objects in packaging film, so that these items can be sent directly without additional envelopes, for example, if the address has either been printed directly on the item beforehand, an address sheet has been packed in the foil, or a label field is subsequently glued to the envelope foil.
  • the content and in particular the external design of the content are fully visible.
  • Known devices of the type mentioned guide the film by means of deflecting rods from both sides of the object over the object to its center and weld the half-tube thus formed there by sealing devices. The film is then welded transversely to the direction of travel between the objects running one behind the other and the objects are thereby completely packaged in an envelope.
  • the present invention is therefore based on the object to improve the known devices of the type described above while avoiding their disadvantages and to lead the film over one side over the entire upper object surface, so that the weld seam from the center of the large surface of the object to a narrow side, especially in books or the like is shifted to the opposite side of the book, so that the image and lettering of a book cover or a catalog surface or similar cuboid objects come into full effect.
  • this object is achieved in a device of the generic type in that, as guide devices for guiding the film web over the object, a deflecting rod extending over several lengths of the objects at a small angle to the direction of travel for deflecting the free half of the film over the objects to one Half hose is arranged; that transport belts are arranged below the film, at least one of which is designed as a suction belt with suction holes, hold the film on the belt by means of the suction pipes with suction openings by means of vacuum; that holding and guide rollers rest on the deflecting rod; that at least one suction belt running above the deflected film part is arranged in the connecting device in the end region of the switches deflecting the film laterally; that diverting points provided are to cause a lateral overlapping of the lower and the upper edge of the film on the narrow side of the objects; and that the connecting devices for connecting the film edges in the running direction of the film are arranged laterally next to the narrow side of the objects for closing the half-tube into a
  • the holding and guiding rollers resting on the deflecting rod ensure good holding and guiding of the film deflected diagonally by the deflecting rod, so that it is guided smoothly over the objects to be packaged.
  • a suction tape running above the deflected film part in the end area of the sealing station enables the film to be held securely when the edges of the film are laid over and over one another by means of switches and when sealing in the edge area, on the object, when sealing from the side or when sealing in the edge area below the object, so that the film does not run.
  • the leading transport belts are returned by a roller and a roller and transport belts are provided which are slower than those to delay the speed of the objects Objects and the belts leading up to the film run.
  • a particularly preferred embodiment of the invention is characterized in that, in the sealing device, the welding stamp has the shape of a cutting-like electrode transverse to the direction of travel of the objects; that cutouts are provided in the side of the electrode cutting edge facing away from the welding point; that the outbreaks are partially filled in their upper part with stable, reinforced insulation material; and that the cross-section of the electrode cutting edge is reduced in a region where the electrode cutting edge presses on the double film layer formed by overlapping the film edges when the film is cross-welded.
  • transverse sealing seams advantageously reduced in width, since a higher temperature is possible with a narrower electrode, and despite the increase in resistance and thus higher temperature in the electrode cutting edge, its stability during fastening is ensured, which is particularly due to the breakouts in it supporting the upper part of the stable, reinforcing insulation material.
  • a further embodiment of the invention provides that liquid-cooled hold-down devices running parallel to the electrode cutting edge of the welding die are arranged to be foldable. This allows the hold-down device to be brought as close as possible to the electrode cutting edge without experiencing an inadmissible increase in temperature which would cause undesired secondary sealing. This option enables the hold-down device to be brought close to the electrode cutting edge supported by a narrow weld.
  • the packaging film 1 for the items to be packaged is obtained from a supply roll 3.
  • the film 1 is transported over conveyor belts 4, 5, one of which is a suction belt 5, in the direction of the sealing station 6.
  • the catalogs 2 lie on the film 1, so that they are carried by the conveyor belts 4, 5.
  • a deflecting rod 7 is attached to holding rods 8 and extends obliquely over a transport length of approximately six catalogs 2.
  • the film 1 is placed over the deflecting rod 7 and is from this guided and deflected, as shown in the sections of Figures 1a to d. Due to the oblique guidance of the deflecting rod 7 over the catalogs 2, the film 1 is continuously guided over the catalogs 2, so that it completely covers the surface of the catalog 2 located there in the place of FIG. 1c.
  • the suction belt 5 which is provided with suction holes 9, is located below the film web.
  • a plurality of vacuum-loaded suction pipes 10 with suction openings 11 are arranged below the suction belt 5 and hold the film 1 firmly by sucking the film 1 through the suction holes 9 and thus prevent it from running.
  • deflecting rod 7 On the deflecting rod 7 there are holding and guide rollers 12 at several points, which firmly press the film 1 onto the deflecting rod 7 and thus support the deflection of the film 1.
  • deflection switches 13 In front of the sealing station 6 deflection switches 13 are attached, which cover the flat edge 14 of the lower part of the film 1 and the edge 15 of the upper part of the film 1, which is largely horizontally stretched by the end region of the deflection rod 7, around edges 16, 17 of the catalog 2 overlay the narrow side of catalog 1 defined between these edges, as can be clearly seen in FIG. 1b.
  • an upper, endless suction belt 18 with suction holes 19 is attached in the area of the sealing station 6, through the suction holes 19 of which the film 1 is held by the opening 21 of further suction pipes 22.
  • a sealing head 23 in the form of a roller 25 provided with a heating coil 24 for welding the half-tube thus formed.
  • a welding stamp 26 is provided for attaching the transverse seals between the successive catalogs 2, as is shown in the upper part of FIG. 1 and in particular in FIGS. 2 and 3.
  • the conveyor belts are interrupted at 27 and the conveyor belts 4 transporting the catalogs 2 and the film 1 to the sealing station 6 run around a roller 28, while new ones the catalogs 1 continuously engage belts 29 around a roller 31 on the underside of the catalogs 2.
  • the rollers 31 rotate at a lower rotational speed than the rollers 28, so that the conveyor belts 29 also run more slowly than the conveyor belts 4, as a result of which the catalogs 2 are somewhat delayed from the roller 31, so that the distance between them decreases and as a result the tension of the previously tight film 1 is released.
  • the welding stamp 26 has a cutting-shaped electrode or electrode cutting edge 32, through which current flows directly via lines 33, 34, which heats up the electrode cutting edge 32 due to the resistance of the latter.
  • the electrode cutting edge 32 is firmly clamped between holding blocks 35. From the side of the electrode cutting edge, which is remote from the film web 1 and is clamped in the holding blocks 35 32 ago the electrode cutting edge 32 is interrupted by cutouts 36 which expand further downward, so that the cutouts have the form of cuts of mushrooms standing upside down. Reinforcements (not visible) made of insulation material are introduced into the cutouts 36 in their upper part between the holding blocks 35.
  • a hold-down 37 folded up can be seen, which in the folded-down state does not rest on the electrode cutting edge 32 on one side, while a corresponding hold-down 37 lies on the other side of the electrode cutting edge 32 and both the film 1 between press catalogs 2 down while sealing.
  • the hold-down devices 37 can be brought extremely close to the electrode cutting edge 32 without heating up inadmissibly (which would result in an undesirable additional lateral welding effect), since they are liquid-cooled via supply and removal hoses 38, 39.
  • the area of the electrode cutting edge 32, which acts on the part of the film 1 during welding, which is thickened by the longitudinal sealing and the consequent overlapping of the edges 14 and 15, is reduced in its cross section, as a result of which an increase in resistance and thus an increase in temperature is brought about .
  • a film 1 coming from the supply roll 3 is placed around the deflecting rod 7 and through the switches 13 in the manner shown in FIG. 1 with the secondary figures a to d.
  • Catalogs 2 are then fed above the conveyor belts 4 and the suction belt 5 and guided under the film half passed from left to right through the deflection rod 7 in FIG. 1 and thus between the film 1.
  • the film 1 is held by the vacuum passing through the suction holes 9 of the suction belt 5.
  • the edges 14 and 15 of the film 1 projecting beyond the edges of the catalogs 2 are placed one above the other by means of deflecting switches 13 next to the catalogs 2 around their edges 16 and 17 perpendicular to the transport plane, preventing them from running through the suction belt 18 are, and then welded by the sealing head 23.
  • the catalogs 2 run on the delayed conveyor belts 29 so that the distance between them is reduced.
  • the welding stamp 26 with its electrode cutting edge 32 is pressed through this intermediate space onto the film 1 and thereby welds the film 1 perpendicular to the direction of transport between the catalogs 2, whereby the catalogs 2 are now completely packed.
