Definitions

  • the present invention relates to the field of manufacturing automatic bags or sachets comprising closing profiles complementary adapted to allow openings and closings successive, at the user's discretion.
  • the present invention now aims to provide new ways of making such sachets or bags comprising complementary closure profiles.
  • the present invention also relates to a machine for implementation of this process, as well as sachets and products intermediates obtained by this process.
  • the forming neck 20 receives the film F at the input state in the planar state (and provided closure means 100 as will be explained later). He gives at the output, the film F shaped into a tube.
  • the expression "tube” or “tubular” should not be considered as limiting to a tubular section of revolution. It also includes especially any polygonal tubular section.
  • the filling chute 30 opens into the forming neck 20 and in the tube formed by the film F at the outlet from this forming neck 20.
  • the longitudinal welding means 40 are adapted to close the tube thus formed by joining the two longitudinal edges of the film F
  • the transverse welding means 50 are preferably adapted to sequentially generate a first transverse weld 52 before a product is introduced into the tube through the chute filling 30, then a second transverse weld 54 when the product has been introduced into the tube, to close a bag around the latter.
  • these two welds 52 and 54 can be generated simultaneously, by both and other cutting means 56 ensuring the separation of the bags, thanks to 50 double welding jaws.
  • the welding means 40 and 50 are preferably formed of heated jaws moving cyclically in approximation and separation of the film in a direction orthogonal to the axis of movement thereof.
  • the aforementioned welding means adapted to ensure welding of the second web 124 can be integrated into the welding means 50 transverse.
  • weld lines of the first web 114 on film F are referenced 115, while the weld line of the second veil 124 on film F is referenced 125.
  • sections T of closure means 100 are sectioned using a cutting tool 80 from a coil reserve 82 as shown schematically in Figure 1 attached.
  • the means 60 adapted to convey sections of means of closure 100 transversely on the film F and weld said means of closure 100 on it, can be the subject of many variants of production. They can generally be in accordance with the means described in documents US-A-4,909,017, US-A-4,617,683, US-A-4,665,862, US-A-4,666,536, US-A-4,878,987 and US-A-4,844,759.
  • these means are essentially in accordance with the provisions described in patent application FR 96 02390 filed on February 27 1996 in the name of the Applicant, according to which the means routing 60 include a straight guide 62, for the means of closure 100, superimposed on film F, transverse thereto, designed to precisely position the closure means 100 on the film F and means 64 for gripping or gripping (pliers, needle or suction head) which proceed by traction on the front end of the closure means 100 and not by pushing on the rear end thereof, to convey the means closure 100 in the above-mentioned rectilinear guide 62.
  • gripping or gripping pliers, needle or suction head
  • sections T of closure means 100 routed and welded to film F preferably have a length equal to maximum at half the width of the film F.
  • sections T of closure means 100 are of preferably deposited and welded on the film F in a centered position according to the width of it.
  • the closure means 100 may include two complementary profiles 112, 122 arranged on respective separate webs 114, 124, as seen in Figures 2 and 4 to 6.
  • the sails 114, 124 carrying the profiles complementary 112, 122 can be connected in the form of a canvas common 130 of U-shaped geometry as seen in Figure 3.
  • the U-shaped fabric 130 may have its convexity directed towards the front or towards the rear in the direction of movement L of the film F.
  • this convexity is preferably turned towards the back.
  • the first web 114 of the closure means is welded on film F at its two longitudinal edges, at 115.
  • the first veil 114 of the closure means 100 may only be welded to the film F on one only from its longitudinal edges. In this case it is preferably from the longitudinal edge of the web 114, located in front with reference to the direction of displacement L of the film F, as illustrated in FIG. 4.
  • the weld 115 formed between the web 114 and the film F prevents detachment of the means of closure 100 when moving the film F.
  • the weld 125 produced on only one longitudinal edge of the second sail 124 is operated on the rear longitudinal edge in reference to the direction of movement L of the film F, as seen on the Figure 5.
  • This weld 125 is thus placed on the mouth of the bag and not on the internal volume side of it. Therefore internal pressure of the bag requests closing profiles 112, 122 in approach and not away.
  • the webs 114 and 124 of the closure means 100 may be provided with longitudinal beads 116, 126 at the level of the edges of the webs 114, 124 to be welded to the film F (these are preferably beads 116, 126 tapered away from the web 114, 124, for example beads of generally triangular cross section such that defined in the French patent application filed in the name of Applicant on June 17, 1997 under N ° 97 07490 and as shown schematically in Figure 6), or even localized layers of material facilitating the welding of the sails 114, 124 at this level.
  • the present invention is particularly applicable to the production of bags based on plastic film F.
  • the present invention can apply to the production of bags based on film F formed from any material equivalent, in particular based on complex film comprising a sheet of paper or metal coated with a layer of plastic material.
  • the support sails 114, 124 profiles 112, 122 of the closure means 100 may have come from molding with their respective profile 112, 122 or be attached to it.
  • the geometry of the complementary sections 112, 122 can be the subject of numerous variant embodiments.
  • the sections 112 and 122 are respectively formed of an element single female and a single male element adapted to enter said female element.
  • a means of closure 100 in which the sections 112 and 122 each comprise several male and female elements respectively juxtaposed such as described for example in document FR-A-2 613 326.
  • profiles 112 and 122 can also include, in a manner known per se, support ribs or buttresses, preferably arranged laterally on the outside of the male elements and female, to guarantee a reliable engagement of these.
  • closure means 100 comprising two support sails 114, 124 of width substantially identical.
  • sails supports 114, 124 of markedly different width.
  • present invention is not limited to the modes of particular achievements which have just been described, but extends to all variants according to his spirit.
  • the step of welding the first web 114 of the means of closure 100, on film F can be operated on the forming machine, filling and closing of bags, immediately upstream of the means 20, during a continuous process, or on the contrary, the first web 114 of the closure means 100 can be welded to the film F during a stage prior to the implementation on the machine of formation, filling and automatic closing illustrated in figure 1, the film F thus equipped with the closure means 100 being conditioned before to be routed to the forming means 20 of said machine for the implementation of the above method.
  • the sachets obtained can have many characteristics complementary to those previously described, such as lines of precut, opening or decoration borders etc ...
