Definitions

  • the subject of the present invention is a method and device for multi-pocket bagging and sachets thus obtained, or also called multi-compartment pouches.
  • the technical sector of the invention is that of the field of bagging by packaging such as bags and especially sachets, produced by flat strips folded and sealed to form bags which are then filled with liquid, pasty, solid or powdery product, and closed.
  • One of the main applications of the invention is the possibility of producing multi-pocket sachets with at least 3 compartments which can each receive a different product, powder or other, such as for example sugar, coffee and powdered milk, thus constituting a complete set for preparing a breakfast, which simplifies the handling and preparation of trays, for example in communities.
  • patent application FR 2 682 932 is known, published on April 30, 1993, on a "Method for producing dose-sachet wafers, the machine for processing as well as the wafers obtained" for containing different products but with injection of the products by nozzles and according to a device which can only be along a vertical advancement axis from two strips of sheets whose width corresponds to that of the plates, or to the sum of that of all the pockets, this which limits the possibilities.
  • the problem posed in order to be able to achieve the above objective of a multi-pocket sachet allowing it to be filled with several different products is to be able to present the various compartments of the same sachet under the filling orifices of said products after having sufficiently opened the volume of each of the pockets by spacing the walls made of a material which is certainly flexible and deformable, but which, because of the particular welds and of a certain inherent rigidity, does not deform sufficiently under the simple weight of the product which is deposited therein or that is made to flow therein to receive the entire 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 carried out in good conditions.
  • a solution to the problem posed is a bag opening device of rectangular shape produced by two walls of flexible material integral on three sides and constituting at least one pocket, such that it comprises in a known manner at least two suction cups arranged face to face so that they can be placed against each wall of said bag and able to pull on it, to open the walls at the fourth side not secured to said pocket:
  • the opening device comprises at at least two pairs, that is to say as many as integral pockets intended to constitute an independent bag, of said suction cups mounted at the end of movable arms relative to fixed guides and forming, between those arranged on the same side and movable simultaneously, a divergent angle whose aperture ⁇ is oriented opposite that of the same aperture ⁇ formed by the arms arranged on the other side and carrying the suction cups which face the leu rs.
  • the device comprises at least two, in fact as many as pockets attached to the same sachet, gas blowing nozzles such as compressed air, oriented in the plane defined by said suction cups joined face to face and each towards the point of contact thereof; this helps to separate the walls not only to ensure the opening of each pocket, but also to inflate it and obtain the deformation of the desired volume.
  • gas blowing nozzles 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 planes of parallel mobility, as the suction cup of the pair of the first set associated with it for the same pocket.
  • the result is a new bagging device and method making it possible to produce bags of rectangular shape, such that they comprise at least two pockets, and preferably three, or more of the same height, produced in a continuous strip of flexible material and double-walled, sealed and closed, each containing a liquid, pasty, solid or powdery product of a given quantity which may be different from that contained in the adjacent pocket of the same sachet, and this in an automatic rapid and reliable manner, whatever that the height of said sachets and the respective width of each pocket are; indeed, in the same sachet, depending on the products to be dosed, some of these may be in greater quantity than others and thus require different pocket widths, at least for two of them. they.
  • 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 at the level of the automatic mechanisms and of the locations of the different bags and of the different pockets relative to the products you want to fill.
  • Figure 1 is a schematic overview of an example of a bagging line according to the method of the present invention.
  • FIG. 2 is a sectional view along II, II ′ of the opening device shown diagrammatically in FIG. 1.
  • FIG. 3 is a top view of the device or upper opening head according to FIG. 2.
  • FIG. 4 is a side view of the device or lower opening head of FIG. 2.
  • Figure 5 is a side view of a bag with 3 pockets according to the invention.
  • said suction cups 12 are mounted at the end of mobile arms 32 relative to fixed guides 21 and forming a divergent angle between them, the opening a of which 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 either capable of pulling on the latter 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 thereof, are mounted on guide supports 17 integral with lever supports 20 which, when separated to simultaneously open the openings 40 of said pockets 2 of the same bag 1, drive them along the guides 21 and thus bring said suction
  • 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.
  • FIG. 2 Such devices are shown in FIG. 2 in transverse view along the plane II, II 'of FIG. 1.
  • 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, one 13 1 located at the top above the pockets and the other 13 2 located at the bottom under 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. 4; which control rods 28 are for example, according to FIG.
  • 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 sealing zone 41, preferably comprising a line 42 for pre-cutting.
  • a sealing zone 41 preferably comprising a line 42 for pre-cutting.
