Definitions

  • the invention relates to a roll paper dispensing system and the method of manufacturing such a roll.
  • the state of the art includes plastic tips of a special shape, which are placed for example inside a mandrel on which the product is wound and which cooperate with complementary supports placed in the dispenser. Without these tips, the roller can not be put in place or can not be used properly.
  • rollers having flanks with a groove each cooperating with a special support are also known: a roll without groove can not be held in the dispenser or the hood of the latter can not close, because of the different size of the roll without throat compared to a roll with grooves.
  • EP-A1-1,782,722 proposes a distribution system, which comprises a strip of absorbent product roll and a distributor.
  • the dispenser comprises a frame and a cover which is mounted movable relative to the frame, between an open position for the introduction of the roll in the dispenser and a closed position of use of the roll.
  • the distributor comprises a first guide and positioning element which is carried by the cover and which is adapted to be received axially in a first housing arranged in the center of a first side of the roll, and a second holding element which is carried by the frame and which is adapted to be received axially in a second housing arranged in the center of a second side of the roll.
  • the first guide and positioning element comprises a generally frustoconical smooth section of decreasing section towards the inside of the dispenser which is adapted to be received axially in the first associated housing of the roller.
  • a roll which does not comprise a frustoconical complementary shape of housing to that of the smooth section will oppose the closure of the distributor cover, because of the different dimensions of the roll without complementary housing with respect to a roller with a frustoconical complementary housing.
  • the smooth section is likely to be driven into the side of the roll which has no complementary housing, forcing the closing of the cover so as to deform the sidewall of the roll.
  • the roller may be able to rotate about its axis of rotation by sliding on the smooth section, and the system is then usable, despite degraded operating conditions .
  • the invention provides an economical means to make captive the couple "distributor, paper roll" without adding to the roll of additional elements.
  • the invention proposes a dispensing system comprising means for opposing the rotation of a roll which does not comprise a complementary housing.
  • the invention proposes a system of the type described above, characterized in that said second guide and positioning element comprises at least one projecting portion on which an inner wall of the second housing is able to slide for the guidance in rotation of the roll if the roll has a complementary shape and which is able to penetrate into the product strip constituting the roll if the roll does not have a complementary shape in order to prevent its rotation.
  • FIG. 1 a system 10 for dispensing an absorbent product strip.
  • the absorbent product is, for example, a paper strip 12, such as toilet paper, which is in the form of a cylindrical roller 14 of axis A.
  • the roller 14 is delimited axially by a first sidewall 16a and a second sidewall 16b opposite axially between them.
  • the roller 14 has a first housing 24a, shown in FIG. figure 3b which is arranged in the center of the first flank 16a of the roller 14 and which has an inner wall.
  • the roller 14 has a second housing 24b, shown in FIG. figure 3a which is arranged in the center of the second flank 16b of the roller 14 and which has an inner wall 25b.
  • the first housing 24a and the second housing 24b are here opposed axially and interconnected by a generally tubular cavity 24 extending along the axis A of the roller 14.
  • the distribution system 10 further comprises a distributor 18 for the distribution of the paper 12, which is made by rotating the roller 14 about the axis A.
  • the dispenser comprises a frame 20 which, advantageously, is fixed integrally to a wall (not shown).
  • the distributor 18 comprises a cover 28 which is mounted to move relative to the frame 20 by means of rotation 30.
  • the rotation means 30 here consist of a pivot link B axis hinge type.
  • the cover 28 is able to open and close thanks to a rotational movement about a transverse axis B orthogonal to the axis A of rotation of the roller 14.
  • the cover 28 is able to occupy an open position for the positioning of the roll 14 and a closed position for the distribution of the paper 12, illustrated in FIG. figure 1 .
  • the frame 20 and the cover 28 may be a single piece, in which case the frame 20 and the cover 28 are for example interconnected by a flexible portion adapted to ensure the opening of the cover 28 relative to the frame 20.
  • the distributor 18 comprises means 22 for holding and guiding the rotation of the roller 14.
  • the means 22 for holding and guiding the rotation of the roller 14 comprise a first holding member 22a which is carried by the frame 20 and which is capable of being received axially in the first housing 24a associated with the roller 14.
  • the first holding element 22a is of the "harpoon” type, known from the prior art, and is of generally cylindrical shape.
  • the first retaining element 22a comprises a hooking section 32 which is arranged axially along the axis A of rotation of the roller 14, in the first housing 24a of the first sidewall 16a of the roller 14.
  • the hooking section 32 comprises radially projecting elements 34, such as fins 34, which extend in a direction that is substantially oblique with respect to the longitudinal axis A of the roll 14, so that the fins 34 oppose the withdrawal. of the first holding member 22a when the latter is pressed into the roll 14, as illustrated in FIG. figure 1 for example.
  • the fins 34 are preferably free to rotate along the axis A relative to the attachment section 32 and the section 32 is fixed relative to the frame 20.
  • attachment section 32 includes a chamfer 36 to facilitate the insertion of the first element 22a for holding in the roller 14.
  • the hooking portion 32 of the first holding member 22a preferably has an axial length 13 equal to or less than one third of the axial length 12 of the roll 14.
  • the first holding element 22a comprises a section 38 fixed in a bore 40 of the frame 20 along the longitudinal axis A of the roller 14.
  • first retaining element 22a comprises a shoulder 42 which cooperates with an annular seat 44 of the bore 40 of the frame 20 so as to prevent the axial displacement along the axis A of the first element 22a for holding outwards of the distributor 18.
  • the means 22 for holding and guiding the rotation of the roller 14 comprise a second holding member 22b which is carried by the movable cover 18.
  • the second element 22b for guiding and positioning comprises a projecting portion 26 which extends axially from an inner face 29 of the cover 28 and which is fixed in rotation.
  • the inner face 29 of the cover 28 is arranged opposite the first side 16a of the roller 14 when the cover 28 is in its closed position, so that the projecting portion 26 is adapted to be received axially in the second housing 24b of the roller 14.
  • the protruding portion 26 is here of generally conical inwardly decreasing section of the dispenser 18, and it has a plurality of plates 48, or teeth.
  • the plates 48 are distributed angularly around the axis A in a regular and symmetrical manner along the axis A, forming a star.
  • Each plate 48 is of decreasing section towards the inside of the dispenser.
  • each plate 48 is delimited by a leading edge 50 which extends obliquely towards the axis A and which is able to cooperate by sliding on the inner wall 25b of the second housing 24b of the roller 14.
  • the second housing 24b has a shape of revolution about the axis A which is complementary to that of the assembly constituted by the plates 48, here a conical or frustoconical shape, to allow the rotation of the roller 14 around the axis A sliding on the plates 48.
  • the generally conical shape of the assembly constituted by the plates 48 allows self-centering of the roller 14 with respect to the cover 28.
  • the second housing 24b has an angle a2 of revolution relative to the axis A which is substantially identical to an angle a1 of the leading edge 50 of each plate 48 relative to the axis A.
  • the optimal angle a1 can be between 30 ° and 55 °.
  • the second housing 24b has a maximum diameter d1 less than or equal to one third of the diameter d2 of the new roll 14.
  • each plate 48 extends axially from the first sidewall 16a of the roll 14 into the second housing 24b of the roll 14, over a length I1 less than or equal to one-third of the total axial length I2, or width, of the roll 14.
  • the edge Attack 50 of each plate 48 is rounded convex shape, without sharp angle.
  • the plates 48 converge axially towards the axis A to form a vertex 46 of rounded shape without sharp angle.
  • the plates 48 of the protruding portion 26 are able to fulfill a first function of guiding and positioning the roller 14, if the roller 14 is a roller 14 said complementary.
  • the roller 14 shown in figures 1 , 3a and 3b is a complementary roll 14.
  • complementary roller 14 is meant a roller 14 whose second housing 24b has a shape of revolution which is complementary to the shape of the projecting portion 26 and plates 48, here a generally conical shape.
  • the plates 48 of the protruding portion 26 are capable of performing a rotational locking function of the roller 14, if the roller 14 is non-complementary.
  • non-complementary roll is meant a roll 15 whose second housing 24b has a shape which is not complementary to the shape of the protruding portion 26, such as the roll 15 illustrated in FIG. figure 4 .
  • the invention also relates to a method of manufacturing the complementary roll 14.
  • the manufacturing process of the complementary roller 14 comprises a step during which is deformed axially a sidewall of the roller 14, here the second sidewall 16b, to form the second housing 24b by means of a tool (not shown) male shaped by frustoconical example driven by a press-type machine, crushing the folds of the paper 12 in the center of the second flank 16b of the roll 14, so that the second housing 24b is able to cooperate by sliding on the plates 48 of the second element 22b of guidance and positioning.
  • the second housing 24b thus formed may have a maximum depth p1 equal to one third of the axial length I2 of the complementary roller 14, and preferably equal to one fifth of this length I2 so as not to deform the roller 14 too much.
  • the maximum diameter d1 of the second housing 24b is less than half the diameter d2 of the roll 14, and preferably less than or equal to one third of the diameter d2 of the roll 14.
  • the conicity of the second housing 24b thus produced does not affect the properties of use of the paper sheets 12 forming the roller 14.

  • the complementary roll 14 comprises a first housing 24a and a second housing 24b of conical shape in each of its flanks 16a and 16b respectively.
  • the means 22 for holding and guiding the complementary roll 14 in rotation may be part of a structural element that is not permanently bonded to the frame 20 of the distributor 18.
  • each plate 48 has a plurality of notches 52, each of which extends axially from the leading edge 50 of the associated plate 48.
  • the notches 52 are able to trap the mandrel when the cap 28 is driven towards its closed position.
  • the notches 52 are arranged in several series, the notches 52 of the same series being arranged in a circle around the axis A of rotation of the roller 14, so that each series of notches 52 is able to trap a mandrel of a determined standard diameter.
  • the function of guiding the complementary roller 14 in rotation and the locking function in rotation of the non-complementary roller 15 are filled by the same elements, here the plates 48 of the projecting portion 26.
  • the rotational guiding function can be filled by a smooth element on which the inner wall 25b of the second housing 24b is able to slide
  • the rotational locking function can be filled by a plurality of projecting elements which are able to penetrate into the product strip 12 of the non-complementary roll 15, in order to oppose the rotation of this roll 15.
