Definitions

  • the present invention relates to a method and device of multi-bagging bags and sachets thus obtained, or also said multi-compartment pockets.
  • the technical sector of the invention is that of the field of bagging by packaging such as bags and especially sachets, made by flat bands folded and sealed to form pockets that are then filled with liquid, pasty, solid or powdery product, and closed.
  • One of the main applications of the invention is the possibility to make multi-pocket sachets with at least 3 compartments each receiving a different product, powder or other, such as by example of sugar, coffee and powdered milk, thus constituting a complete set to prepare a breakfast, which allows to simplify handling and preparation of trays, for example in communities.
  • the problem posed to be able to achieve the above objective of multi-pouch bag allowing to be filled with several products different is to be able to present the various compartments of the same sachet under the filling orifices of said products after having sufficiently open the volume of each pocket by spacing walls made of flexible and deformable material, but which, due in particular to the welds and to a certain inherent rigidity, does not deform sufficiently under the simple weight of the product that is inside drop in or drop in to receive the full volume of the desired dose: it is therefore necessary to pre-spread the walls of each pocket to the maximum of their volume so that the filling is then do in good conditions.
  • the opening device has at least two pairs, in fact as many as integral pockets to constitute a sachet independent, of said suction cups mounted at the end of movable arms by compared to fixed guides, which movable movable arms simultaneously and their associated fixed guides, arranged on the same side of the pocket, form two by two between them a divergent angle whose opening ⁇ is oriented opposite that of the same opening ⁇ formed by the arms arranged on the other side and carrying the suction cups which face theirs.
  • the device comprises at least two, in fact as many pockets attached to the same bag, blowing nozzles gases such as compressed air, oriented in the plane defined by said suction cups placed side by side and each towards the contact point of these; this helps the separation of the walls not only to ensure the opening of each pocket, but also to inflate it and obtain the deformation of the desired volume.
  • gases such as compressed air
  • the device according to the invention comprises two sets of pairs of suction cups arranged and movable in parallel planes, each suction cup of the pairs of the second set being in the same plane, perpendicular to said parallel mobility planes, that the suction cup the pair of the first set associated with it for the same pocket.
  • the result is a new bagging device and method allowing to make bags of rectangular shape, such as have at least two pockets, preferably three or more same height, at least two of them being of different width, made in a continuous strip of flexible material and double-walled, sealed and closed, each containing a product liquid, pasty, solid or powdery of a given amount different from that contained in the adjacent pocket of the same sachet, and this automatically and quickly and reliably, whatever the height of said sachets and the respective width of each pocket; in effect, in the same sachet, depending on the products you want dose, some of these may be in larger quantities than others and thus require different pocket widths, at least for two of them.
  • Such a device and method can be used in any type of bagging lines known to date, such as those shown in the figures below, with of course an adaptation in terms of automatisms and locations of the different sachets and the different pockets relative to the products you want to fill.
  • said suction cups 12 are mounted at the end of arms 32 movable relative to fixed guides 21, which fixed guides each associated with a movable arm and arranged with a same side of the strip 5, form a divergent angle two by two, of which the opening ⁇ is oriented facing the plane defined by said strip 5, so that each suction cup 12 can be placed against each wall of a pocket 2 of said bag and is able to pull on it to open said pockets, in particular by a suction device 44 creating a depression in the center of each suction cup.
  • Said arms 32 supports are mounted on guide supports 17 integral with lever supports 20 which, when you push them aside to simultaneously open the openings 40 of said pockets 2 of the same bag 1, cause the arms 32 along the guides 21: thus the suction cups 12 are brought together which are arranged on the same side of the bag 1, each pulling and thus causing one of the walls of a pocket, so that they follow the deformation of these.
  • the pockets 2, by opening, will indeed bring their common lateral sides closer to the adjacent pockets of the same bag 1: the suction cups 12, using the device of the invention, following their converging guide 21, will get closer the same.
  • the pockets are not of the same width l 1 and if it is then of course to open the widest further to deposit a larger dose of product, it is necessary to separate the suction cups 12 therefrom, a greater distance than the others: this is possible by having two lever supports 20 as described below, articulated at the end situated on the side of the narrowest pocket 2, and then giving the closest suction cups 12 from their axis of rotation Z 1 , Z ′ 1, a spacing displacement smaller than those which are the most distant.
  • two pairs of suction cups 12 are available per bag 2, the second 12 2 lower being located between the bottom 34 of said pockets and those 12 1 upper ensuring the opening 40 of said pocket: these two sets of pairs of suction cups 12 are each preferably carried in a separate device or head, l '13 1 located at the top above the pockets and the other 13 2 located at the bottom below them.
  • a fixed support block 36 is integral with the assembly of the frame 30 of the machine of the bagging line 43 and door guides 21, fixed, preferably two per suction cup to maintain it in one plane and located one above the other in a plane parallel to the desired displacement of the latter and at angles ⁇ , ⁇ open towards said bag 1 and as defined above: for three pockets 2 and therefore three pairs of arms 32, said angles ⁇ , ⁇ formed by these and therefore their guides 21, shown in FIG. 3 are determined as a function of width l of each pocket 2 and therefore of their deformation when they are opened, determining the approximation value of the suction cups required.
  • the two lever supports 20 are articulated, either directly for the upper head 13 1 around axes Z 1 , Z ' 1 , or indirectly by two lever arms 37 driving connecting pieces 38 with a Y axis connected to said lever supports 20 which then pivot and move apart each along an axis Z 2 Z 2 'for the lower head 13 2 .
  • Said lever supports 20 articulated, drive said supports 17 of the suction cup arms 32, by means of rolling rollers 33 which can move in windows 31 1 made in said lever supports 20, in the desired direction to follow both the spacing and convergence of the suction cups 32: for this, the guide supports 17 of the suction cup arms slide on said fixed guides 21 which impose on them the angle and the orientation of movement, the levers 20 ensuring the amplitude of said movement.
  • either different devices or heads 13 1 , 13 can be produced for each type of bag, or it can be provided a minimum of adjustment of the position of said suction cups 12 relative to their support 17 2 such as by windows 39 made in said supports 17, in which said nozzle supports 12 2 are blocked by any means of attachment, or it is possible to change and adapt as for the upper assembly 13 1 the arms ends 32 of the nozzles which, as in FIG. 3, are bayonet-shaped and whose part parallel to the plane defined by the set of nozzles 12 which is also that walls of the strip 5 before deformation, are more or less long for this.
  • control rods 28 are connected to the end of said levers 20, either directly in the case of the example of the upper head 13 1 , or indirectly by the set of arms and connecting pieces 37, 38 in the case of the lower head 13 2 of FIG.
  • control rods 28 are for example, according to Figure 2, driven by secondary control levers 27 whose movement is ensured by connecting rods 26, whose reciprocating movement is controlled by a main control lever 24, articulated to one of its ends around an axis A: at its other end, this control lever 24 carries a bearing 23 held in contact by a spring 25 against a cam 22 rotated at the desired speed;
  • a drive device is perfectly known in different existing bagging lines and can simultaneously ensure the functions of all other workstations, such as those shown in Figure 1, from the same tree cam control 22.
  • the suction cups 12 1 On the upper head 13 1 , in order to help the spacing of the walls sucked by the suction cups 12 1 , there are preferably arranged as many nozzles 18 as pockets 2 for blowing a gas such as air 19 which, in addition to to help the opening 40, also allows the entire bag to swell and completes the work of the lower suction cups 12 2 .
  • a gas such as air 19
  • a bag 1 of rectangular shape as shown in FIG. 5, comprising at least two sealed pockets 2, or three as shown, produced in the same continuous strip 5 of flexible material and with double walls, sealed and closed and each containing a product of a given quantity 14 which may be different from that contained in the adjacent pocket of the same sachet 1; said bag thus comprises, according to FIG. 5, three pockets 2 of the same height h, at least two of which 2 1 and 2 2 are of different width l 1 , l 2 , ie l 1 > l 2 in order to receive in the pocket 2 1 a product 14 1 in quantity greater than that 14 2 of the bag 2 2 .
  • Each pocket 2 is connected to the adjacent one by a zone 41 of sealing, preferably comprising a line 42 for pre-cutting.
  • a zone 41 of sealing preferably comprising a line 42 for pre-cutting.
