Definitions

  • the present invention relates to a shaping device for forming an inflow hose according to the preamble of independent claim 1.
  • a folding device in order to form an inflow hose package from a packaging material web fed from a roll.
  • a guide fork and a folding plate with a U-shaped cross section are provided to form the side walls of the hose. Both the guide fork and the folding plate are held on a support so that they can be adjusted on all sides.
  • To form the bottom surface there are folding tongues provided with guide horns pointing upwards.
  • An improvement of the folding device is achieved with a shaped shoulder according to DE-A-1 179 495.
  • a mandrel is therefore covered with an externally sticky shell.
  • This surface is in turn surrounded by a flexible film in such a way that one end of the film is correctly shaped into a tube, while the other end of the film is a flat surface.
  • the shape of the film corresponds to a tape that runs in on the one hand and is then formed into a tube.
  • the pocket formed by the film is poured out with a mass that solidifies without significant shrinkage, and after the film has solidified, the film and casing are removed. The body obtained forms the desired shape shoulder.
  • a shaping device according to the preamble of claim 1 is known, in which objects continuously fed at a distance from one another are wrapped by means of a band-shaped plastic film.
  • a guide body that penetrates the transport plane guides the plastic film.
  • the guide body has a longitudinal slot at the bottom for guiding sealable edge parts of the film.
  • This device is only suitable for insensitive, stretchable, non-wrinkling films, since the deformation of the approximately flat surface pulled off from a roll into a tubularly curved surface enclosing the objects generates considerable shear forces in the film in this known device.
  • a very sensitive packaging material such as the aluminum foil mentioned, places the highest demands on the packaging machines. These include: a smooth, bumpless conveying speed and smooth starting, as well as precise and sensitive traction control.
  • a further transport device which can be synchronized precisely with the running-in speed.
  • a strip-shaped aluminum foil 1 is fed from a dispensing roller 2 via deflection rollers 3a, 3b, 3c, 3d to the guide body 4, where it is now placed on a horizontal conveyor device 5 fed items are folded.
  • the sealing station 6 Downstream of the guide body 4 is the sealing station 6, of which only two sealing rollers 6c, 6d, which are arranged in pairs and are each rotatably driven with a vertical axis 6a, 6b, are shown.
  • the second deflection roller 3b is pretensioned via a two-armed lever 8 which is rotatably mounted on a rotational axis 7 fixed to the frame and with a spring 9 in order to maintain a constant tension in the aluminum foil 1. Since this tape guide is generally known, there is no need to go into this at this point.
  • the conveying device 5 for the articles G is also known and can have a structure as described in CH-A-527 090. Accordingly, the objects G are pushed on a horizontal track 50 fixed to the frame from guide rails 51 with a central longitudinal slot 52 (see FIGS. 5 and 6) by drivers 53 in the direction of arrow A.
  • the drivers 53 are rotatably connected to a transport chain 54 which rolls on a support 55 fixed to the frame and can be connected in a known manner, e.g. are deposited against the transport direction by a run-up curve (not shown) so that they cannot injure the aluminum foil 1 or the objects G when they pass over the chain deflecting roller 56.
  • the guide rails 51 taper in the transport direction and are omitted entirely in the area where the lateral par tien the aluminum foil 1 are folded around the items G.
  • the task of the guide body 4 is to reshape the aluminum foil 1 from its original, newly supplied state into a tube without tensile forces.
  • the side view of this guide body 4 is clearly shown in FIG. 1 and the bottom view in FIG. 1 is shown in FIG. 2, while the shape of the body is illustrated in five sectional views, FIGS. 3 to 7.
  • the guide body 4 is symmetrical with respect to a perpendicular plane.
  • the intersection line 40 of this perpendicular plane with the guide body 4 is shown in broken lines in FIG. 2. Since the aluminum foil 1 is delivered flat and rests on an upstream part of the guide body 4 and leaves it as a tube S, the aluminum foil 1 in turn nestling against a wall, a first main shaping surface 41 and a second main shaping surface 42 can be distinguished.
  • the section line 40 which is shown in FIG. 1 as the lower contour line of the first main shaping surface 41, is at least approximately straight up to a point 43 from which it is bent into a horizontal straight line 40a.
  • the two edge parts 45a, 45b of the first main shaping surface 41 have a smaller pitch angle than the central straight line 40.
  • the aluminum foil 1 is thus deformed from its flat state according to FIG. 3 into a concave shape according to FIG. 4.
  • the second main shaping surface 42 begins from point 43.
  • the objects G press the aluminum foil in its central part against the horizontal part 40a of the central straight line 40 (FIG. 5).
  • the edges are thickened in a bead-like manner with a rounded ridge 46a, 46b when the two main shaping surfaces penetrate, so that the aluminum foil 1 can slide over it.
  • the two edge parts 45a, 45b are pulled down shortly after the point 43, at the section line IV in FIG. 1, below the transport plane according to the guide rails 51, and the rounded ridges 46a, 46b approach each other according to FIG. 6.
  • the guide rails 51 taper in an arrow shape, because from there the ridges 46a, 46b with the adjoining portions of the second main shaping surface 42 support the objects G in the newly formed tube.
  • the edge parts 45a, 45b of the first main shaping surface 41 and the remaining remnants of this surface form a slot 47 for the edges of the aluminum foil 1, which are only to be connected to one another by a seal.
  • the film is shaped uniformly.
  • the two rounded ridges 46a, 46b cause the film to roll evenly against the objects, so that the film does not have to perform any other sliding movement apart from the sliding movement in the direction of the center line. This ensures that only a tensile force is exerted on the film in the direction of transport and that the film cannot tear under the action of differently directed forces.
  • a bulge 43 with a rounded ridge portion 48a and an upstream concave curvature 48 was formed at the kink of the middle straight line 40.
  • the packaging material 1 undergoes a first slight reshaping at this transition point in that the web width is reduced by the amount of this bead. This excess material in the middle of the web allows the subsequent forming into a hose to be stress-free.
  • 41 spherical glass particles with a diameter of 0.2 to 0.4 mm can be embedded in the sliding surface of the first main shaping surface.
  • the shaping body 4 can be divided along the middle straight line 40. For larger objects, the width of the channel between the edge parts 45a, 45b can thus be increased by inserting intermediate pieces.
