Definitions

  • the present invention relates firstly to a method by which a first portion of a label is folded over a second portion of the same label according to the preamble of claim 1. It also relates to a device capable of carrying out said method.
  • Patent EP-B-0.514 340 describes a method and a device by which various operations are carried out for the preparation of a packaging blank, respectively of a label.
  • the device described in particular comprises a drum on the cylindrical lateral surface of which a label is maintained, various preparation operations being successively carried out during the rotation of the drum.
  • One of these operations consists in folding down a first portion of the label by 180 ° onto a second portion of the same label.
  • the patent in question indicates that this operation is carried out using a semi-helical guide rail. Since the label is placed on a cylindrical drum, the fold line around which the fold is to be made is arched according to the diameter of the drum.
  • a first object of the present invention is therefore to precisely define a method by which this folding operation is carried out, while a second object of the invention, as defined in the claims 5 to 11, is to specify the characteristics of a folding device suitable for this operation.
  • FIG. 1 shows a label 1 held on the external cylindrical surface of a rotating drum 2, the label being arranged longitudinally and parallel to the axis of rotation of the drum, folding means 3 being provided for folding down the portion 10 of the label 1 on the portion 11 around the range line 12; pressure roller means 4 are arranged at the outlet of the pad means 3 in order to consolidate the fold or, if necessary, if a drop of glue has been placed on one of the portions 10 or 11 before the fold is carried out, by means not shown arranged upstream of the folding means 3, to consolidate the bonding of the folded portion.
  • the drum 2 comprises in particular a first support disc 20 on which the portion of the label 1 close to the fold line 11 is supported.
  • FIG. 2 represents, seen in perspective, the guide or shaping rail 30, which is the main element of the folding device 3 according to the invention, on which a plurality of label portions 1 are seen to pass, in order to describe the different stages of folding down the surface portion 10 on the adjacent portion 11 around the fold line 12.
  • the rail 30 is here shown seen from its concave face.
  • the portions represented of the labels 1 relate only to the central part at the end of the label 1, the shape of the latter having been simplified compared to the shape shown in the figure. 1 so as not to overload the figure.
  • the label 1 is maintained on the drum 2, not shown in this figure, the different labels represented here corresponding to different angular positions of the drum, respectively various stages of the process.
  • the shaping rail 30 consists of a preferably metallic piece, having the general shape of a circular crown segment, of relatively small thickness. It comprises a first portion 30A extending over approximately a third of the length of the rail 30, followed by a second portion 30B extending over most of the length of the rail 30, then a third portion 30C, relatively short and constituting the end of the rail 30. As can best be seen in FIG.
  • the edge 31 on the first portion 30A of the rail 30 directed towards the drum 2, respectively towards the first support disc 20, is perpendicular to the longitudinal axis of said drum, while the same edge 32 on the second portion 30B takes the form of a helix directed towards the drum 2, and that the edge 33 corresponding to the portion 30C is again perpendicular to the longitudinal axis of the drum 2.
  • the outer face of the portion 30A, respectively the convex part of this portion of the rail 30 is cut in a bevel so as to have a surface 34 in the form of a portion of a truncated cone inclined towards the edge 31 , the axis of said truncated cone being coincident with the axis of rotation of the drum 2; the theoretical apex of this truncated cone would be on said axis, in the direction of the drum. It can be seen in FIG.
  • this surface 34 has a general shape of a triangle, that its height increases rapidly from the upstream end of the porton 30A, ie from the nose 35 of said portion, to a maximum value and then slowly decreases until the end of portion 30A. It may be recalled that the end of this surface 34 facing the drum 2, respectively the edge 31 is perpendicular to the axis of the drum 2.
  • this surface 36 On the other face of the rail 30, that is to say on the concave part of the latter, there is also a bevel cut, defining another surface 36, also in shape portion of truncated cone, the axis of which also coincides with the axis of rotation of the drum 2, but the apex of which is in the direction opposite to that of the drum.
  • the intersection of this surface 36 with the internal face of the rail has the general shape of a triangle, its height increasing from a point located near the nose 35 of the portion 30A, to a maximum value located on the meeting line between the portions 30A and 30B then decreasing on the portion 30B to cancel out on the meeting line between the portions 30B and 30C.
  • the end of this surface 36 facing the drum therefore corresponds to the edge 31 on the portion 30A and then to the edge 32 of helical shape on the portion 30B.
  • the surface 37 corresponding to the concave internal face of the portion 30C simply has the shape of a circular cylindrical portion.
  • FIGS. 3B and 5B show a portion of a label 1 seen in profile, arranged on the drum 2 in rotation and moving towards the shaping rail 30 in order to fold the surface portion 10 around the fold line 12 to fold it over the surface portion 11 as indicated by the arrow.
  • FIG. 3B it can be seen that the label 1 is held on the drum 2 in a position such that the fold line 12 is very slightly set back towards the drum relative to the edge 31 of the portion 30A.
  • the different folding steps can now be followed in FIG. 2.
  • the label 1 therefore comes upstream of the portion 30A of the rail 30, being positioned as we have just seen.
  • the portion 10 of the label engages on the convex part of the rail 30, respectively on the surface 34 located on the other side of the rail 30 as shown in Figure 2 where the portion 10 begins to fold, being guided by the surface 34.
  • the folding angle increases regularly until reaching 90 ° when the label reaches the end of the portion 30A, ie at the start of the portion 30B, respectively at the point where the helical edge 32 begins.
  • the label is then guided by the surface 36 located on the concave face of the rail 30 where the fold continues to form until the surface portion 10 is completely folded over the portion 11 when the label 1 arrives on the portion 30C.
  • the surface portion 10 of the label 1 has been folded back 180 ° from the entry to the exit of the label on the rail 30.
  • FIGS. 3A and 3B a first embodiment of the means for holding and guiding the label is shown in FIGS. 3A and 3B, their operation being described with reference to FIGS. 4A to 4F.
  • These holding means 5 are arranged on the first support disc 20, which in this case has a support surface, on which the label 1 rests, wider than that shown in FIG. 1, or which can be offset in the direction of the shaping rail 30, so that the label 1 can rest on this surface up to the fold line 12 (see upper part of FIG. 3B).
  • suction nozzles 50 On this bearing surface of the disc 20, suction nozzles 50 have been distributed along the same generatrices of the drum 2 as the suction nozzles described in the patent mentioned above.
  • the suction nozzles 50 are connected to the same suction device as the suction nozzles of the patent mentioned above and operate simultaneously with them. If it is desired that the label 1 remains flat during folding, it is possible to provide a frame 51 surrounding the mouth of each nozzle 50 on the bearing surface of the disc 20, thus defining a plane bearing surface, or then create a flat at the mouth of each nozzle 40 (see FIG. 3A).
  • FIGS. 4A to 4F Several stages of the folding process are shown in FIGS. 4A to 4F which correspond respectively to the state of the label 1 along lines A to F of FIGS. 3A and 3B.
  • FIG. 4A the label 1 has not yet entered the folding device, it is firmly held on the support disc 20, in particular by a suction nozzle 50.
  • FIG. 4B the portion 10 has then been slid on the convex side of the portion 30A of the shaping rail 30 and is therefore supported on the surface 34 which begins to form the fold.
  • FIG. 4C also shows a subsequent step where the portion 30A already includes the surface 36 on its concave face, the folding here is mainly carried out by the edge 31 which is always parallel to the fold 12. In the step shown in FIG.
  • the portion 10 has tilted from the convex face to the concave face of the rail 30, over the helical edge 32 and is now guided by the surface 36 of the portion 30B of the shaping rail 30.
  • This tilting operation is caused by the offset of the rail 30 relative to the disc 20 as described below.
  • the portion 10 is completely folded over the portion 11, the fold being held by the surface 37 against the surface d support of the support disc 20. In order to fully form the fold 12, it is then crushed by a roller 40 pressing firmly against the support surface of the disc 20.
  • the roller 40 is mounted on suspension means 41, for example spring-loaded, so as to be able to maintain a constant pressure despite the shape irregular of the bearing surface of the disc 20. It was indicated in the aforementioned patent that a device for depositing one or more spots of adhesive was placed before the pad device so that after folding the portion surface 10 ad hère on the corresponding portion 11; the support exerted by the roller 40 on the portion 10 folded over the portion 11 bearing on the bearing surface of the bearing disc 20 makes it possible to consolidate this bonded bond. On examining FIGS.
  • the rail 30, respectively its portions 30A, 30B and 30C or the edges 31 and 32 move relatively to the bearing surface of the bearing disc 20; this is not the case, the rail 30 is absolutely fixed, this effect of relative displacement being obtained by an offset of the surfaces of the cylindrical segment of the rail 30 relative to the cylindrical periphery of the support disc 20, so that the nose 35 of the portion 30A is tangent or slightly inside the envelope of the periphery of the support disc 20 and the portion 30C is slightly spaced from this periphery (see FIG. 3A), the support surface 37 of said portion 30C then being coaxial with the cylindrical bearing surface of the disc 31 in order to keep the fold closed, maintained between the two said surfaces, as seen in FIG. 4E.
  • the edge 31, 32 of the shaping rail 30 progressively passes from a tangent position or below the cylindrical bearing surface of the disc to an external position, parallel to said cylindrical bearing surface, label 1 exactly following the periphery of disc 31, will see its portion 10 engage on the surface 34 disposed outside of the rail 30 then later after having tilted over the edge 31.32 at the moment when said edge crosses the cylindrical bearing surface of the disc, it will see said portion 10 follow the surfaces 36 then 37 located inside the rail 30.
  • the second embodiment of the holding and guiding means described below corresponds to the preferred embodiment of these; this embodiment is shown in Figures 5A and 5B, different stages of the action of these means during the folding process being shown in Figures 6A to 6G in the same manner as above.
  • the folding and holding means according to this embodiment consist only of fixed and stationary elements excluding the drum 2 in rotation.
  • the shaping rail 30 is absolutely identical to that described above, but unlike the previous embodiment, the support disc 20 no longer comes in close proximity to the fold line 12 but is clearly set back from this line, as shown in FIG. 5B.
  • the means 6 for holding the label 1 during the folding operation comprise, apart from those described in the patent mentioned above and arranged on the drum 2, a first internal support rail 60 and a second external support rail 61 provided with a support tab 62, these elements as well as the shaping rail 30 being fixed and immobile.
  • the first internal support rail 60 consists of a circular ring segment generally disposed inside the concave surface of the rail 30, so as to present a cylindrical offset support surface 63 in the exact extension of the surface support of the disc 20, it generally provides support on the back of the label 1 before and during the folding thereof; consequently, the circumference portion covered by the rail 60 also extends upstream from that covered by the rail 30.
  • the second external support rail 61 also consists of a circular crown segment; it is arranged parallel to the rail 60, on the side of the drum 2, but is not exactly coaxial with it.
  • the concave face of this rail 61 has a cylindrical surface 64 disposed opposite the bearing surface 63 of the rail 60, the spacing between the surfaces 64 and 63 decreasing, passing from a large spacing towards the upstream parts of the rails 60 and 61, leaving the label 1 relatively free between the surfaces 63 and 64, at a reduced spacing towards the parts downstream of said rails where the folded portion 10 is pressed on the portion 11 of the label 1 as we will see below.
  • a portion of the back of the label 1 rests on a portion of the bearing surface 63 of cylindrical shape while a portion of the opposite face of the label 1 is guided or maintained by the second support rail 61.
  • the fold line 12 will therefore take an arcuate shape during said path.
  • the essential part of the second support rail 61 consists of a support tongue 62 projecting from a portion of a circle on the inside of the rail 61 closest to the shaping rail 30, said tongue having an edge directed towards the bearing surface 63 of the rail 60 and whose length and position correspond approximately to that of the portion of the surface 36 located on the portion 30A of the rail 30. (see FIG. 5B).
  • the way in which the shaping rail 30 cooperates with the holding means consisting of the first support rail 60 and the second support rail 61 described above, in order to make the fold around the beach line 12, is shown in Figures 6A to 6G.
  • the label 1 is held on the drum 2 as described in the previously mentioned patent.
  • its portion disposed behind the folding line 12, ie on the side of the rest of the label 1 comes to bear on the bearing surface 63 of the inner bearing rail 60 and engages under the bearing surface 64 of the outer bearing rail 61 without coming into direct contact with said surface.
  • the portion 10 of the label 1 meets the surface 34 of the portion 30A of the shaping rail 30.
  • the end of label 1 is slightly raised; due to the spacing of the two bearing surfaces 63 and 64, the portion of the label 1 comprising the fold line 12 can be straightened so as to be relatively straight in this place, that is to say not arcuate .
  • the fold around the fold line 12 can be initiated before the latter is arched again.
  • the fold is accentuated even that the label has an arcuate shape, the surface portion slightly behind the beach line 12 being strongly pressed by the edge of the tongue 62 against the surface d 'support 63.
  • the fold is more and more pronounced; the pinching of the label 1 between the edge of the tongue 62 and the bearing surface 63 giving the arcuate shape described in the fold line, cooperating with the increase in the folding angle caused by the surface of support in the form of a truncated cone portion 34 creates a tilting of the surface portion 10 around the arcuate fold line 12, the fold being now guided by the edge 31.
  • FIG. 6E it can be seen that the label 1, after the mentioned tilting, has passed on the other side of the rail 30, and is now opposite the portion 30B of the rail 30. It is the surface 36, the edge 32 of which has the helical shape mentioned previously , which contributes to continuing the formation of the fold.
