Abstract

The dispenser (10), comprising a housing with a supporting rod (30) for a roll of material which is dispensed by pulling on its end, has the rod inclined at an angle to the horizontal so that one side of the roll is pressed against one of the housing's vertical walls (14,18) to provide a brake on the rotation of the roll. The dispenser wall against which the roll is pressed has a friction zone with projecting radial ribs (46).

Description

L'invention concerne un distributeur pour bande de matériau en rouleau comportant une tige support inclinée.The invention relates to a dispenser for a strip of rolled material. comprising an inclined support rod.

L'invention concerne plus particulièrement un distributeur pour bande de matériau en rouleau, notamment pour du papier tel que l'ouate de cellulose, du type dans lequel le rouleau comporte un alésage central qui permet son montage sur une tige support du distributeur. Le distributeur présente par exemple la forme d'un boítier à l'intérieur duquel est contenu le rouleau et une extrémité libre de la bande de papier en rouleau est destinée à traverser une ouverture de distribution.The invention relates more particularly to a dispenser for a strip of roll material, especially for paper such as cellulose wadding, type in which the roller has a central bore which allows its mounting on a distributor support rod. The distributor presents for example the shape of a box inside which is contained the roller and one end free of the strip of roll paper is intended to pass through an opening of distribution.

Ainsi, en tirant sur l'extrémité libre de la bande de papier, l'utilisateur provoque le dévidage du papier par rotation du rouleau autour de l'axe de la tige support.Thus, by pulling on the free end of the paper strip, the user causes the paper to be unwound by rotating the roller around the axis of the rod support.

Si l'effort de traction que l'utilisateur exerce sur le papier est relativement énergique, le rouleau peut acquérir une certaine vitesse de rotation autour de la tige du support et, si rien n'est prévu, l'énergie cinétique emmagasinée par le rouleau risque de provoquer un dévidage excédentaire du rouleau, au-delà de la longueur de papier souhaitée par l'utilisateur.If the tensile force exerted by the user on the paper is relatively energetic, the roller can acquire a certain rotation speed around the support rod and, if nothing is provided, the kinetic energy stored by the roller may cause excess unwinding of the roll, beyond the length of paper desired by the user.

On connaít par les brevets US A 2523951 et US A 5653403 des supports de rouleaux dont l'axe est en positon inclinée à 45°. En s'appuyant sur un élément dont la surface est perpendiculaire à l'axe, le rouleau est freiné dans son mouvement de rotation autour de celui-ci. Toutefois de tels systèmes augmentent l'encombrement des rouleaux. Ils ne sont adaptés aux rouleaux de grands diamètres que l'on trouve dans les collectivités. L'invention a pour objet de proposer un distributeur de bande de matériau en rouleau qui comporte des moyens pour assurer le freinage du rouleau qui soient à la fois simples et efficaces quelle que soit la géométrie effective de ce dernier.We know from the patents US A 2523951 and US A 5653403 roller supports whose axis is in position inclined at 45 °. By relying on an element whose surface is perpendicular to the axis, the roller is braked in its rotational movement around it. However such systems increase the size of the rollers. They are only suitable for rolls of large diameters found in communities. The object of the invention is to propose a material strip dispenser in roll which includes means for braking the roll which are both simple and efficient whatever the effective geometry of this latest.

Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
  • Figure 1 is a schematic perspective view with cutaway of a dispenser according to the teachings of the invention; and
  • FIG. 2 is a partial view in section on a vertical plane passing through the support rod of the dispenser of FIG. 1.

On a représenté sur les figures 1 et 2 un distributeur 10 pour une bande de matériau en rouleau, notamment pour des rouleaux de papier. Le distributeur 10, en forme de boítier, est par exemple prévu pour recevoir des rouleaux de grande dimension du type de ceux qui sont destinés aux collectivités.FIGS. 1 and 2 show a distributor 10 for a strip of roll material, in particular for rolls of paper. The distributor 10, in the form of a housing, is for example provided to receive large rolls of the type of those which are intended for communities.

Le distributeur 10 est destiné à être fixé contre un mur vertical et il comporte un socle 12 dont une paroi verticale 14 s'étend le long du mur et forme la paroi verticale arrière du boítier, lequel est refermé vers l'avant par un capot 16 qui est monté pivotant par son extrémité inférieure sur le socle 12 autour d'un axe A1 horizontal sensiblement parallèle au mur sur lequel le distributeur 10 est fixé.The distributor 10 is intended to be fixed against a vertical wall and it comprises a base 12, a vertical wall 14 of which extends along the wall and forms the rear vertical wall of the housing, which is closed forward by a cover 16 which is pivotally mounted by its end lower on the base 12 around a substantially horizontal axis A1 parallel to the wall on which the distributor 10 is fixed.

Comme on peut le voir sur les figures, le capot 16 comporte une paroi transversale 18 qui délimite à l'avant le volume interne du distributeur 10 et des parois latérales 20, 21 qui déterminent la profondeur du boítier selon une direction horizontale perpendiculaire au mur.As can be seen in the figures, the cover 16 includes a transverse wall 18 which delimits at the front the internal volume of the distributor 10 and side walls 20, 21 which determine the depth of the housing in a horizontal direction perpendicular to the Wall.

Comme on peut le voir plus particulièrement sur la figure 1, le socle 12 comporte, à son extrémité inférieure, un bandeau 22 qui délimite une ouverture inférieure 24 du distributeur 10. La bande de papier est destinée à être dévidée au travers de cette ouverture 24 qui est ouverte vers le bas.As can be seen more particularly in FIG. 1, the base 12 has, at its lower end, a strip 22 which delimits a lower opening 24 of the distributor 10. The strip of paper is intended to be unwound through this opening 24 which is open down.

En effet, comme on peut le voir plus particulièrement sur la figure 2, le distributeur 10 est destiné à recevoir un rouleau 26 de matériau en bande.Indeed, as we can see more particularly on the Figure 2, the distributor 10 is intended to receive a roller 26 of strip material.

Le rouleau 26, cylindrique d'axe A3, comporte un mandrin tubulaire central 28 sur lequel est enroulée la bande de matériau. L'enroulement ainsi formé présente deux faces latérales transversales 40, 42 qui sont sensiblement parallèles aux parois transversales 14, 18 du distributeur 10.The roller 26, cylindrical with axis A3, has a mandrel central tubular 28 on which the strip of material is wound. The winding thus formed has two transverse lateral faces 40, 42 which are substantially parallel to the transverse walls 14, 18 distributor 10.

Le mandrin tubulaire 28 présente donc un alésage central 29 afin de permettre le montage du rouleau 26 sur une tige de support 30 qui s'étend vers l'avant depuis la paroi transversale arrière 14 du socle 12.The tubular mandrel 28 therefore has a central bore 29 so allow the mounting of the roller 26 on a support rod 30 which extends forward from the rear transverse wall 14 of the base 12.

Conformément aux enseignements de l'invention, la tige de support 30 s'étend selon un axe A2 qui est contenu dans un plan vertical perpendiculaire au mur sur lequel est fixé le distributeur 10 et qui forme avec la direction horizontale H un angle α tel que l'extrémité axiale avant libre 32 de la tige support 30 est au-dessus de son extrémité arrière qui est liée au socle 12. L'angle α peut par exemple être de l'ordre de 5 à 10 degrés.In accordance with the teachings of the invention, the rod support 30 extends along an axis A2 which is contained in a vertical plane perpendicular to the wall on which the distributor 10 is fixed and which forms with the horizontal direction H an angle α such that the axial end free front 32 of the support rod 30 is above its end rear which is linked to the base 12. The angle α can for example be around 5 to 10 degrees.

Ainsi, sous l'effet de son poids, le rouleau 26 est en porte-à-faux sur la tige support, et il a tendance à s'orienter selon cet angle par basculement autour d'un axe horizontal sensiblement perpendiculaire à la tige 30, jusqu'à ce qu'une génératrice supérieure 36 du mandrin 28 soit au contact, sur toute sa longueur, avec une génératrice supérieure 38 de la tige support 30.Thus, under the effect of its weight, the roller 26 is cantilevered on the support rod, and it tends to orient itself at this angle by tilting around a horizontal axis substantially perpendicular to the rod 30, until an upper generator 36 of the mandrel 28 either in contact, along its entire length, with an upper generator 38 of the support rod 30.

Cependant, la profondeur du distributeur 10 est prévue pour être peu supérieure à la largeur axiale de la bande de papier qui constitue le rouleau 26. De la sorte, le rouleau 26 tend à se mettre en appui par la partie périphérique de ses faces transversales arrière 40 et avant 42 contre les parois transversales arrière 14 et avant 18 qui délimitent le boítier du distributeur 10.However, the depth of the distributor 10 is provided for be little more than the axial width of the paper strip which constitutes the roller 26. In this way, the roller 26 tends to become support by the peripheral part of its rear transverse faces 40 and front 42 against the rear transverse walls 14 and front 18 which delimit the distributor housing 10.

Plus précisément, la face interne 44 de la paroi avant 18 du capot 16 comporte deux nervures en relief 46 qui s'étendent selon une direction sensiblement radiale autour de l'axe A2 de la tige de support 30.More specifically, the internal face 44 of the front wall 18 of the cover 16 has two raised ribs 46 which extend in a substantially radial direction around the axis A2 of the support rod 30.

Les nervures 46 s'étendent sensiblement à 120° l'une par rapport à l'autre, en dessous du niveau de la tige support 30. Elles présentent en section orthogonale un profil semi-cylindrique dont la partie arrondie coopère avec la face transversale avant 42 du rouleau.The ribs 46 extend substantially at 120 ° relative to one another. to the other, below the level of the support rod 30. They have at orthogonal section a semi-cylindrical profile whose rounded part cooperates with the front transverse face 42 of the roller.

Les nervures 46 forment donc une zone de frottement contre laquelle le rouleau est en appui de telle manière que l'axe A3 du rouleau 26 reste sensiblement horizontal, la génératrice supérieure 36 du mandrin 28 n'étant alors pas en contact sur toute sa longueur avec la génératrice supérieure 38 de la tige de support 30.The ribs 46 therefore form a zone of friction against which the roller is in support so that the axis A3 of the roller 26 remains substantially horizontal, the upper generator 36 of the mandrel 28 then not being in contact over its entire length with the upper generator 38 of the support rod 30.

Les nervures 46 permettent de limiter la surface de contact du rouleau 26 avec la paroi transversale avant 18 et leur forme arrondie permet d'éviter que les nervures ne provoquent un déchirement du matériau en bande, notamment lorsqu'il s'agit de papier.The ribs 46 make it possible to limit the contact surface of the roller 26 with the front transverse wall 18 and their rounded shape prevents the ribs from tearing the strip material, especially in the case of paper.

Le rouleau 26 est aussi en appui par sa face transversale arrière 40 contre une zone de frottement 48 de la paroi transversale arrière 14 du socle 12. Toutefois, la zone de frottement 48 de la paroi transversale arrière 14 est elle agencée au-dessus du niveau de la tige support 30.The roller 26 is also supported by its rear transverse face 40 against a friction zone 48 of the rear transverse wall 14 of the base 12. However, the friction zone 48 of the transverse wall rear 14 is it arranged above the level of the support rod 30.

Grâce à l'invention, le rouleau 26 est donc en appui contre des zones de frottement 46, 48 du distributeur 10, essentiellement par des parties périphériques de ses faces transversales 40, 42.Thanks to the invention, the roller 26 is therefore in abutment against friction zones 46, 48 of the distributor 10, essentially by peripheral parts of its transverse faces 40, 42.

Il en résulte que le couple des efforts de frottement du rouleau 26 contre les parois 14, 18 du distributeur tend à diminuer avec le diamètre du rouleau 26. Ainsi, au cours du dévidage du rouleau, l'effort résistant qui permet de freiner le rouleau diminue en même temps que diminue le moment d'inertie du rouleau.It follows that the torque of the friction forces of the roller 26 against the walls 14, 18 of the dispenser tends to decrease with the diameter of the roller 26. Thus, during the unwinding of the roller, the force resistant which makes it possible to brake the roller decreases at the same time as reduces the moment of inertia of the roller.

De plus, l'utilisation d'une tige de support inclinée permet de garantir l'appui du rouleau 26 par ses faces transversales 40, 42 contre les parois transversales 14, 18 du distributeur quel que soit le gauchissement du rouleau, c'est-à-dire quelle que soit la forme géométrique exacte des faces transversales 40, 42 qui peut être irrégulière en fonction des variations de positionnement axial que peut présenter la bande de papier par rapport au mandrin 28 au cours de son enroulement.In addition, the use of an inclined support rod allows guarantee the support of the roller 26 by its transverse faces 40, 42 against the transverse walls 14, 18 of the distributor whatever the warping of the roller, i.e. whatever the shape exact geometry of the transverse faces 40, 42 which can be irregular depending on variations in axial positioning that may present the strip of paper with respect to the mandrel 28 during its winding.

Selon un autre aspect de l'invention, la tige de support 30 peut être agencée à plusieurs altitudes dans le distributeur 10. Dans l'exemple de réalisation illustré sur les figures, la tige 30 peut occuper deux positions discrètes différentes mais on peut aussi envisager que la tige support soit montée sur une glissière solidaire du socle et qu'elle soit pourvue de moyens de verrouillage lui permettant d'être fixée à différents niveaux de hauteur.According to another aspect of the invention, the support rod 30 can be arranged at several altitudes in the distributor 10. In the example shown in the figures, the rod 30 can occupy two different discrete positions but we can also consider that the rod support is mounted on a slide secured to the base and is provided with locking means allowing it to be fixed to different height levels.

Dans l'exemple de réalisation illustré sur les figures, la tige support 30 comporte, à son extrémité axiale arrière 34, une plaque transversale 50 qui est munie, à son extrémité supérieure, d'au moins un crochet supérieur 52 destiné à être engagé dans l'une de deux fentes 54 formées dans la paroi transversale arrière 54 du socle 12, et, à son extrémité inférieure, d'au moins un pion inférieur 56 qui est susceptible d'être emboíté élastiquement dans l'un de deux orifices 58 correspondants aménagés eux aussi dans la paroi transversale arrière 14.In the embodiment illustrated in the figures, the rod support 30 comprises, at its rear axial end 34, a plate transverse 50 which is provided at its upper end with at least one upper hook 52 intended to be engaged in one of two slots 54 formed in the rear transverse wall 54 of the base 12, and, at its lower end, of at least one lower pawn 56 which is susceptible to be fitted resiliently in one of two orifices 58 correspondents also arranged in the rear transverse wall 14.

Bien entendu, les fentes 56 et les orifices 58 sont agencés par paires de manière que lorsque le crochet supérieur 52, qui est courbé vers le bas, est engagé dans une fente 54, qui est sensiblement horizontale, le pion 56 est emboíté axialement dans l'orifice 58 correspondant de manière à assurer la fixation de la plaque 50.Of course, the slots 56 and the orifices 58 are arranged by pairs so that when the upper hook 52, which is bent down, is engaged in a slot 54, which is substantially horizontal, the pin 56 is fitted axially in the orifice 58 corresponding so as to secure the plate 50.

Plus précisément, une face interne 57 de la paroi transversale arrière 14 comporte un renfoncement 59, au fond duquel sont aménagés les fentes 56 et les orifices 58, et dans lequel la plaque 50 est reçue de manière à ne pas dépasser axialement en avant de la face interne 57.More specifically, an internal face 57 of the transverse wall rear 14 has a recess 59, at the bottom of which are arranged the slots 56 and the orifices 58, and in which the plate 50 is received from so as not to protrude axially in front of the internal face 57.

Par ailleurs, comme on peut le voir sur la figure 1, le distributeur 10 comporte une tige de support auxiliaire 60 qui est escamotable et qui est agencée à l'extrémité inférieure du distributeur 10, sensiblement au niveau du bandeau 22.Furthermore, as can be seen in Figure 1, the dispenser 10 has an auxiliary support rod 60 which is retractable and which is arranged at the lower end of the dispenser 10, substantially at the level of the strip 22.

La tige auxiliaire 60 est articulée autour d'un axe horizontal transversal A4 sur la paroi arrière 14 du socle 12 et elle est susceptible d'être rabattue sensiblement dans le plan de cette paroi 14, verticalement vers le haut, pour être reçue dans un logement 62 correspondant aménagé dans la paroi arrière 14. En position abaissée, la tige auxiliaire 60 s'étend en travers de l'ouverture inférieure 24. The auxiliary rod 60 is articulated around a horizontal axis transverse A4 on the rear wall 14 of the base 12 and it is susceptible to be folded down substantially in the plane of this wall 14, vertically upwards, to be received in a corresponding housing 62 fitted in the rear wall 14. In the lowered position, the rod auxiliary 60 extends across the lower opening 24.

La tige auxiliaire 60 est destinée à recevoir un rouleau 26 lorsque celui-ci est presque entièrement dévidé. Ainsi, un tel rouleau peut être terminé tout en permettant à en un rouleau neuf d'être installé sur la tige support principale 30 de telle sorte que, lorsque le premier rouleau est terminé, l'utilisateur peut se servir du second rouleau sans qu'il n'y ait de discontinuité dans l'approvisionnement.The auxiliary rod 60 is intended to receive a roller 26 when it is almost completely unwound. So, such a roller can be finished while allowing a new roll to be installed on the main support rod 30 so that when the first roller is finished, the user can use the second roller without there is no discontinuity in supply.

Éventuellement, comme on peut le voir sur la figure 1, on peut prévoir que la face interne du bandeau 22 soit pourvue elle aussi d'une nervure de frottement 64 destinée à freiner le rouleau installé sur la tige auxiliaire 60.Optionally, as can be seen in Figure 1, we can provide that the internal face of the strip 22 is also provided with a friction rib 64 intended to brake the roller installed on the rod auxiliary 60.
