Description

L'invention se rattache au secteur technique des appareils de-distribution de papier d'essuyage en ouate de cellulose, papier crêpé, et matériaux similaires destinés plus particulièrement à l'essuyage des mains des utilisateurs de papier toilette, tels que ceux selon le préambule de la revendication 1.The invention relates to the technical sector of distribution devices cellulose wiping paper, crepe paper, and the like intended more particularly for wiping the hands of paper users toilet, such as those according to the preamble of claim 1.

Il existe de très nombreux appareils distributeur de matériaux d'essuyage à fonctionnement automatique ou semi-automatique et le demandeur a développé plusieurs appareils de ce type permettant la distribution de bandes de matériau plié ou non plié. Ces appareils qui font l'objet d'exploitation satisfaisantes sont du type comprenant un carter moulé en matière plastique recevant en partie haute une bobine d'alimentation en matériau d'essuyage, un tambour contenant un dispositif de coupe à lame dentelée, ainsi qu'un moyen presseur assurant l'alimentation de la bande de papier vers le tambour, et la mise en tension du papier. La lame de coupe est articulée dans le tambour en étant mise en mouvement par la coopération d'un talon denté fixe associé à l'axe de la lame de coupe et coopérant avec un moyen à crémaillère positionné fixement et intérieurement sur une des ailes du carter. Une disposition de ce type a notamment été décrite dans le brevet français n° 2701016 du demandeur. Par ailleurs, l'extrémité de ce tambour est associée à un mécanisme de lancement avec excentrique et ressort de rappel décrit et illustré dans le brevet FR 2340887.There are many devices for dispensing wiping materials at automatic or semi-automatic operation and the applicant has developed several devices of this type allowing the distribution of strips of material folded or unfolded. These devices which are subject to satisfactory operation are of the type comprising a molded plastic casing receiving at the top a reel for supplying wiping material, a drum containing a serrated blade cutting device, as well as a pressing means ensuring feeding the paper web to the drum, and tensioning the paper. The cutting blade is articulated in the drum by being placed movement by the cooperation of a fixed toothed heel associated with the axis of the blade cutting and cooperating with a rack means fixedly positioned and internally on one of the housing wings. A provision of this type has in particular has been described in French patent No. 2701016 of the applicant. Through elsewhere, the end of this drum is associated with a launching mechanism with eccentric and return spring described and illustrated in the FR patent 2340887.

Néanmoins, l'effort de traction nécessaire pour développer la bande de matériau en vue de sa coupe est important, de l'ordre de un kilogramme. Cet effort peut être augmenté en fonction de la qualité des matériaux traités, de leur épaisseur, et de leur présentation en plis ou non pliés selon l'agencement de l'appareil. Nevertheless, the tensile force necessary to develop the strip of material for its cutting is important, of the order of one kilogram. This effort can be increased depending on the quality of the materials treated, their thickness, and their presentation in folds or unfolded according to the arrangement of the device.

Le demandeur a donc développé des recherches complémentaires pour améliorer encore la fiabilité de fonctionnement de l'appareil et réduire les efforts nécessaires pour l'utilisateur lors de la traction effectuée sur la bande de matériau.The applicant therefore developed additional research to further improve the operating reliability of the device and reduce efforts necessary for the user when pulling on the belt material.

La réduction des efforts de traction a amené ainsi le demandeur à s'intéresser plus particulièrement au dispositif permettant la rotation du tambour sur lui-même et autorisant la sortie de la lame de coupe. On a ainsi représenté à la figure 1 des dessins un appareil distributeur selon l'art antérieur décrit dans le brevet français n° 2701016, correspondant au préambule de la revendication 1. Un moyen à crémaillère est monté sur l'arbre du tambour et présente une pluralité de dents formant crémaillère, les premières dents étant à profil constant, les suivantes à profil progressif, pour provoquer les mouvements de la lame de coupe. Par ailleurs, la lame présente à son extrémité susceptible d'être mise en regard du moyen crémaillère une pièce-fixe formant talon présentant une pluralité de dents formant pignon et étant disposée en éloignement progressif par rapport à l'axe de la lame, la dent d'attaque étant de hauteur plus grande pour assurer l'engrènement. Cette pièce formant talon est solidaire de l'axe de la lame dans une position excentrée, de manière à provoquer le pivotement angulaire de la lame et de la pièce formant talon. Dans cette mise en oeuvre particulière, on observe qu'il y a un positionnement relatif continu sensiblement à 90° entre le point d'attaque de la lame de l'engrenage, l'articulation du porte-lame et le bout ou zone de coupe de la lame selon l'axe identifié XOX. Cette angulation (α) est constante pendant toute la rotation du tambour, lors de la coupe d'un format de bande de matériau.The reduction in tensile forces thus led the applicant to focus on the device for rotating the drum on itself and authorizing the exit of the cutting blade. We have thus represented at the FIG. 1 of the drawings a dispensing device according to the prior art described in the French patent n ° 2701016, corresponding to the preamble of claim 1. A rack and pinion means is mounted on the shaft of the drum and has a plurality of teeth forming a rack, the first teeth with a constant profile, the following with a progressive profile, to cause movements of the cutting blade. Furthermore, the blade has at its end likely to be compared with the rack means a fixed part forming heel having a plurality of pinion teeth and being arranged in progressive distance from the axis of the blade, the leading tooth being greater height to ensure meshing. This heel piece is secured to the axis of the blade in an eccentric position, so as to cause the angular pivoting of the blade and of the piece forming the heel. In this bet in particular work, we observe that there is a continuous relative positioning substantially at 90 ° between the point of attack of the gear blade, the articulation of the blade holder and the tip or cutting area of the blade along the axis identified XOX. This angulation (α) is constant throughout the rotation of the drum, when cutting a strip of material format.

Le demandeur dans le cadre de ses recherches a donc imaginé la possibilité de modifier cette angulation pour voir s'il pouvait y avoir des effets sur la force de traction de la bande de matériau tirée par l'utilisateur.The applicant in the course of his research therefore imagined the possibility to modify this angulation to see if there could be effects the tensile force of the strip of material pulled by the user.

D'une manière surprenante, il est apparu qu'une modification substantielle de cette angulation par un accroissement de son amplitude avait pour résultat de réduire la force de traction nécessaire au tirage de la bande de papier améliorant ainsi d'une manière non négligeable le confort d'utilisation de l'appareil.Surprisingly, it appeared that a substantial change of this angulation by an increase in its amplitude resulted in reduce the tensile force required to pull the strip of paper thus in a significant way the comfort of use of the device.

Ainsi, selon l'invention, le mécanisme à talon denté, tel que défini dans le préambule de la revendication 1, comprend un bras articulé à l'encontre d'un moyen élastique de rappel par rapport au porte-lame, ledit bras présentant une forme curviligne avec une pluralité de dents susceptibles de coopérer avec le moyen à crémaillère dans un montage flottant élastiquement, et en formant une angulation définie par le point d'attaque de l'engrenage, l'axe d'articulation du talon denté et la zone de coupe de la lame qui se situe sensiblement entre 160 et 170°.So according to the invention, the heel mechanism toothed, as defined in the preamble of claim 1, includes an arm articulated against an elastic means of return relative to the blade holder, said arm having a curvilinear shape with a plurality of teeth capable of cooperating with the means to rack in an elastically floating assembly, and forming a angulation defined by the point of attack of the gear, the axis of articulation of the toothed heel and the cutting area of the blade who lies substantially between 160 and 170 °.

L'effet de ces caractéristiques ressortira bien de la suite de la description.The effect of these characteristics will become clear from the rest of the description.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

De manière connue, l'appareil distributeur pour essuie-mains et papier toilette référencé dans son ensemble par (1), comprend un carter (2) moulé en matière plastique susceptible de recevoir dans sa partie haute une bobine (3) d'alimentation en matériau d'essuyage ou papier toilette maintenue entre des flasques (4) porte bobine supérieurs rapportés, sur le fond du carter ou autrement. Des flasques inférieurs (5) sont rapportés sur la face de fond (2a) du carter et sont aménagés avec des échancrures autorisant la fixation et le montage du tambour (6), lequel inclut un dispositif de coupe (7) à lame dentelée (7a). Ce dispositif de coupe est particulier de la manière décrite précédemment avec un agencement sur l'un des côtés du tambour qui comprend un mécanisme à talon (8) dentelé associé à la lame de coupe qui coopère avec une crémaillère fixe (9) établie sur le flan intérieur (5b) de ladite flasque (5) du carter. Le tambour présente une ouverture longitudinale (6f) permettant le passage et la sortie de la lame de coupe. Le tambour est agencé de manière connue de son autre coté avec un agencement non illustré aux dessins et correspondant à l'enseignement du brevet français FR A 2 340 887, et incluant un mécanisme de lancement et de rappel avec excentrique et ressort L'appareil comprend en outre un moyen presseur (11) sous forme de cylindre et de longueur correspondante à celle du tambour qui est susceptible d'être en appui sur celui-ci, en étant positionné entre les flasques (5) précités.In known manner, the dispenser for paper towels and paper toilet referenced as a whole by (1), includes a housing (2) molded in plastic material capable of receiving in its upper part a coil (3) supply of wiping material or toilet paper maintained between flanges (4) upper reel holders attached, on the bottom of the housing or other. Lower flanges (5) are attached to the bottom face (2a) of the casing and are fitted with notches allowing fixing and mounting drum (6), which includes a cutting device (7) with a serrated blade (7a). This cutting device is particular in the manner described above with a arrangement on one side of the drum which includes a heel mechanism (8) serrated associated with the cutting blade which cooperates with a fixed rack (9) established on the inner blank (5b) of said flange (5) of the housing. The drum has a longitudinal opening (6f) allowing the passage and the exit of the cutting blade. The drum is arranged in a known manner on its other side with an arrangement not illustrated in the drawings and corresponding to the teaching of French patent FR A 2 340 887, and including a launch and recall mechanism with eccentric and spring The apparatus further comprises a pressing means (11) in the form of a cylinder and of length corresponding to that of the drum which is likely to be supported on it, being positioned between the flanges (5) supra.

Selon l'invention, la crémaillère fixe (9) comprend une pluralité de dents (9a) établie dans le profil et la configuration définis dans le brevet FR 2701016. Par contre, le mécanisme à talon (8) est agencé en ce qu'il comprend un bras articulé (8a) à l'encontre d'un moyen élastique de rappel (12) dont une extrémité (12.1) est fixée à une patte (7b) disposée sur le porte-lame du dispositif de coupe et l'autre extrémité (12.2) est fixée audit bras. Ce dernier comprend à sa base (8.b) une forme en bague susceptible de s'engager à pivotement sur un doigt (13.a) ménagé en saillie sur un bossage fixe (13b) établi sur le porte-lame d'une manière rapportée ou moulée.According to the invention, the fixed rack (9) comprises a plurality of teeth (9a) established in the profile and configuration defined in patent FR 2701016. By cons, the heel mechanism (8) is arranged in that it comprises an arm articulated (8a) against an elastic return means (12), one end of which (12.1) is fixed to a tab (7b) arranged on the blade holder of the cutting device and the other end (12.2) is fixed to said arm. The latter includes at its base (8.b) a ring shape capable of pivotally engaging on a finger (13.a) projecting from a fixed boss (13b) established on the blade holder of a reported or molded.

Ledit bras (8a) se prolonge dans sa partie avant en forme de secteur curviligne (8c) dont la face supérieure présente une pluralité de dents du type correspondant aux dents (8d) formées sur le talon dentée décrit dans le brevet 2701016. Ledit bras est donc susceptible d'une articulation à montage élastique flottant. Lors de la rotation du tambour en vue de la coupe, ledit bras est susceptible de s'écarter par rapport au porte-lame du dispositif de coupe en modifiant ainsi l'angulation (α1) qui est définie par le point d'attaque de l'engrenage, l'axe d'articulation du talon denté et la zone de coupe de la lame. On obtient ainsi une angulation selon YOY qui se situe sensiblement entre 160 et 170 °. Cette amplitude est sensiblement constante lors de la rotation du tambour. Elle permet par le montage flottant du bras (8a) formant pignon de réduire d'une manière substantielle la force de traction nécessaire de la bande de matériau qui a été mesurée ainsi à environ 300 à 400 grammes. Cette réduction est due au fait que la force de résistance du tambour lors de sa rotation est moindre de par la souplesse de la liaison et de l'engrènement de la crémaillère et du talon précité. On obtient ainsi un meilleur confort d'utilisation de l'appareil.Said arm (8a) extends in its front part in the form of a sector curvilinear (8c) whose upper face has a plurality of teeth of the type corresponding to the teeth (8d) formed on the toothed heel described in the patent 2701016. Said arm is therefore capable of an articulation with elastic mounting floating. When the drum is rotated for cutting, said arm is likely to deviate from the blade holder of the cutting device in thus modifying the angulation (α1) which is defined by the point of attack of the gear, the hinge pin of the toothed heel and the cutting area of the blade. We thus obtains an angulation according to YOY which is substantially between 160 and 170 °. This amplitude is substantially constant during rotation of the drum. She permits by the floating mounting of the arm (8a) forming a pinion to reduce in a way substantial the necessary tensile force of the strip of material which has been thus measured at around 300 to 400 grams. This reduction is due to the fact that the resistance of the drum during its rotation is less due to the flexibility of the connection and the engagement of the rack and the aforementioned heel. We obtain thus a better comfort of use of the device.

Les avantages ressortent bien de la description.The advantages are apparent from the description.
