Description

L'invention se rattache au secteur technique des appareils de distribution de papier d'essuyage en ouate de cellulose, en papier crêpé et en matériau similaire destiné plus particulièrement à l'essuyage des mains des utilisateurs, à la distribution de papier toilette, à la distribution de serviettes en papier.The invention relates to the technical field of wiping paper dispensing devices made of cellulose wadding, creped paper and similar material intended more particularly for wiping the hands of users, the distribution of toilet paper, the distribution of paper towels.

Le demandeur a développé de nombreux brevets sur les appareils du type précité avec un concept de base défini dans les brevets français n° 2.332.215 , n° 2.340.887 .The applicant has developed numerous patents on apparatus of the aforementioned type with a basic concept defined in French patents no. 2332215 , No. 2340887 .

Ainsi, on rappelle succinctement les caractéristiques de tels appareils. Ceux-ci comprennent essentiellement un carter (1) présentant un fond (1a) et deux ailes latérales (1b), ledit carter se prolongeant dans sa partie basse avec un profil incliné (1c), l'ensemble présentant un profil adapté pour permettre la réception et l'articulation d'un couvercle (2). Dans sa partie basse, le carter est susceptible de recevoir, de manière connue, un tambour (3), creux intérieurement, pour recevoir un dispositif de coupe (4). Dans la partie haute, le carter reçoit deux flasques (5a) (5b) susceptibles de recevoir, à articulation, un porte-bobine (6) ayant des embouts (6d) supports d'alimentation d'une bobine de matériau d'essuyage (b). La bobine d'essuyage prend appui sur le tambour (3) en permettant le passage et le déroulement de la bande de matériau à l'arrière de l'appareil entre le tambour et la paroi de fond du carter, de sorte que ladite bande de matériau soit susceptible de déboucher dans la partie basse de l'appareil. Le tambour présente sur sa périphérie une bande auto-agrippante (3a) en contact avec le matériau pour permettre la tenue et faciliter le déchirement après opération de coupe. Pour assurer une tenue de 1a bobine de matériau sur le tambour, il est nécessaire d'exercer une certaine pression d'appui constante, durant tout le déroulement de la bobine de matériau, quels que soient les efforts effectués.Thus, we briefly recall the characteristics of such devices. These essentially comprise a housing (1) having a bottom (1a) and two lateral wings (1b), said housing extending in its lower part with an inclined profile (1c), the assembly having a profile adapted to allow the receiving and hinging a lid (2). In its lower part, the housing is capable of receiving, in known manner, a drum (3), hollow internally, to receive a cutting device (4). In the upper part, the casing receives two flanges (5a) (5b) capable of receiving, with articulation, a spool holder (6) having end pieces (6d) support supports for a spool of wiping material ( b). The wiping spool is supported on the drum (3) allowing the passage and unwinding of the material web at the rear of the apparatus between the drum and the bottom wall of the housing, so that said web of material is likely to open into the lower part of the appliance. The drum has on its periphery a self-gripping band (3a) in contact with the material to allow holding and facilitate tearing after cutting operation. In order to ensure that the reel of material on the drum is held, it is necessary to exert a certain constant bearing pressure throughout the course of the reel of material, regardless of the forces exerted.

Dans le cadre de développement d'appareils du type précité, il a été introduit, dans la partie basse de l'appareil, un rouleau de sécurité (7) pouvant être associé à une courroie de guidage (8) et de transmission liant les rouleaux de sécurité et ledit tambour. Une disposition de cette nature a notamment été décrite dans le brevet français n° 2.555.975 .In the development of devices of the aforementioned type, it has been introduced, in the lower part of the apparatus, a safety roller (7) can be associated with a guide belt (8) and transmission linking the rollers safety device and said drum. A provision of this nature has in particular been described in French patent no. 2555975 .

Le tambour peut être décrit du type de celui décrit dans les brevets français précités, mais il peut prévoir en variante, selon le brevet français n° 2656601 , deux ouvertures (3b) formées à la périphérie du tambour et permettant l'orientation et l'engagement des parties de bande de matériau correspondantes en cas de traction angulaire de l'extrémité de la bande de papier par l'utilisateur, traction non conforme à une traction normale définie dans le prolongement avant de l'appareil.The drum may be described of the type described in the aforementioned French patents, but may alternatively provide, according to the French patent no. 2656601 two apertures (3b) formed at the periphery of the drum and permitting the orientation and engagement of the corresponding material web portions in case of angular pulling of the end of the paper web by the user, non-conforming traction to a normal pull defined in the front extension of the appliance.

Le demandeur a également développé un dispositif particulier permettant le contrôle du bon déroulement de 1a bande de papier à matériau en fonction du diamètre et du poids du rouleau de papier, en fonction de la tension de traction exercée sur l'extrémité débordante du papier en sortie d'appareil. Un tel dispositif a été décrit dans le brevet français n° 2.764.278 .The applicant has also developed a particular device for controlling the smooth running of the paper web according to the diameter and weight of the paper roll, depending on the tensile stress exerted on the projecting end of the paper output. apparatus. Such a device has been described in French Patent No. 2764278 .

Dans le cadre de l'exploitation des appareils du type précité, mettant en oeuvre tout ou partie des caractéristiques rappelées succinctement, le demandeur a constaté, à l'usage, un problème de tenue de la bobine de matériau par rapport à ses flasques support (5a - 5b). Quelles que soient les caractéristiques desdits flasques et de leur réalisation, on constate à l'usage un léger basculement de la bobine vers la gauche, selon une inclinaison (α) de quelques degrés, provoquant l'arrêt de fonctionnement de l'appareil et la non distribution du papier.In the context of the exploitation of the apparatus of the aforementioned type, using all or part of the characteristics recalled briefly, the applicant has found, in use, a problem of holding the reel of material with respect to its support flanges ( 5a - 5b). Whatever the characteristics of said flanges and their implementation, there is the use a slight tilting of the coil to the left, at an inclination (α) of a few degrees, causing the shutdown of the device and the no paper distribution.

Cette situation a été constatée indépendamment de la force de traction effectuée par l'utilisateur, et ce quelle que soit la configuration du tambour.This situation was observed independently of the traction force performed by the user, regardless of the configuration of the drum.

Les flasques supports (5a - 5b) de bobine viennent alors en appui entre les ailes (1b) du carter et l'on constate des effets de coincement de la bande de papier qui ne peut sortir directement par l'ouverture basse de l'appareil.The support flanges (5a - 5b) of coil then bear against the wings (1b) of the housing and there are jamming effects of the paper web that can not come out directly through the lower opening of the device .

Pour remédier à cet inconvénient, l'utilisateur doit alors actionner le bouton de chargement (9) manuel disposé latéralement à l'appareil qui provoque la rotation du tambour et la sortie de la bande de matériau. L'action sur le bouton de chargement est obligatoire pour mettre l'appareil en état de fonctionnement. Si cette manipulation n'est pas réellement gênante en soi, elle cause néanmoins un certain désagrément à l'utilisateur qui a l'impression d'avoir alors un appareil dont le fonctionnement est aléatoire. Cela nécessite aussi que l'utilisateur ait l'idée d'actionner le bouton de chargement, ce qui est loin d'être évident si l'on considère que ces types d'appareils distributeurs sont disposés dans des lieux publics où il y a une multitude d'utilisateurs potentiels.To overcome this disadvantage, the user must then operate the loading button (9) arranged laterally to the device that causes the rotation of the drum and the output of the material web. The action on the load button is mandatory to put the device in working order. If this manipulation is not really troublesome in itself, it nevertheless causes some inconvenience to the user who has the impression of having then a device whose operation is random. This also requires the user to have the idea of pressing the load button, which is far from obvious if we consider that these types of dispensing devices are located in public places where there is a multitude of potential users.

Le document US 4 621 755 définit le préambule de revendication 1.The document US 4,621,755 defines the preamble of claim 1.

La démarche du demandeur a donc été de rechercher à améliorer le fonctionnement de tels appareils distributeurs de matériau d'essuyage en évitant des interventions ponctuelles sur le bouton de chargement, en permettant une distribution de bandes de matériau automatique et régulière face à un contrôle constant du positionnement de la bobine de matériau à l'intérieur de l'appareil.The applicant's approach has therefore been to seek to improve the operation of such dispensers of wiping material by avoiding occasional interventions on the loading button, allowing a distribution of automatic and regular material strips against a constant control of the material. positioning the coil of material inside the apparatus.

Selon une première caractéristique, l'appareil de distribution de bande de matériau d'essuyage à coupe automatique du type comprenant un carter (1) présentant un fond (1a), deux ailes latérales (1b) et se prolongeant dans sa partie basse avec un profil incliné (1c) et recevant un couvercle (2), ledit carter recevant un tambour (3) creux intérieurement avec une fente longitudinale recevant un dispositif de coupe (4) avec lame de coupe articulée, et des flasques latéraux (3d), ledit carter recevant deux flasques (5a - 5b) agencés à articulation pour recevoir un porte-bobine (6) support d'une bobine de matériau d'essuyage (b), ledit tambour présentant, sur une partie de sa périphérie, une bande auto-agrippante (3 a), ledit tambour étant associé à des moyens de lancement, une excentrique (10) et ressort de rappel (11) et un bouton de chargement (9), est caractérisé en ce qu'il comprend un dispositif de contrôle et de repositionnement de la bobine de matériau d'essuyage intervenant à chaque tour de rotation du tambour, ledit dispositif (12) étant aménagé sur le tambour et ayant un contact ponctuel avec la bobine à chaque tour de rotation du tambour en provoquant la remise en place de ladite bobine.According to a first feature, the automatic cut wiper material strip dispensing apparatus of the type comprising a housing (1) having a bottom (1a), two lateral wings (1b) and extending in its lower part with a inclined profile (1c) and receiving a cover (2), said housing receiving a drum (3) internally hollow with a longitudinal slot receiving a cutting device (4) with an articulated cutting blade, and lateral flanges (3d), said housing receiving two flanges (5a - 5b) arranged to articulate to receive a spool carrier (6) supporting a spool of wiping material (b), said drum having, on a part of its periphery, a self-adhesive strip gripping means (3a), said drum being associated with launching means, an eccentric (10) and return spring (11) and a loading button (9), is characterized in that it comprises a control device and repositioning the coil of wiper material ge occurring at each revolution of rotation of the drum, said device (12) being arranged on the drum and having a point contact with the coil at each revolution of rotation of the drum causing the repositioning of said coil.

Selon une deuxième caractéristique, l'appareil est caractérisé en ce que le dispositif comprend sur l'un des flasques latéraux (3d) d'extrémité du tambour, une zone d'épaisseur en saillie en forme de doigt (12), ledit tambour étant aménagé en regard dudit doigt avec une zone lisse (3g) en rupture de la zone agrippante (3a), la largeur de ladite zone lisse entre les parties auto-agrippantes étant telle qu'il n'y a que le contact avec la bobine.According to a second characteristic, the apparatus is characterized in that the device comprises, on one of the lateral flanges (3d) of the end of the drum, a zone of finger-shaped projecting thickness (12), said drum being arranged opposite said finger with a smooth zone (3g) breaking the gripping zone (3a), the width of said smooth zone between the self-gripping parts being such that there is only contact with the coil.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These and other characteristics will be apparent from the rest of the description.

Le dispositif de contrôle et de repositionnement de la bobine de matériau, selon l'invention, est conçu de la manière suivante. L'un (3d) des disques latéraux du tambour, avantageusement celui disposé côté droit de l'appareil correspondant à la partie inclinaison basse constatée de la bobine de matériau, présente, directement par moulage ou rapportée, une zone d'épaisseur en saillie en forme de doigt (12) pouvant être en contact avec la bobine de matériau (b) une fois par tour de rotation du tambour. Par ailleurs, le tambour présente, en regard du positionnement dudit doigt (12), une zone lisse (3g) en rupture avec la zone agrippante (3a). On a représenté ainsi aux dessins une telle disposition. La position en saillie du doigt (12) est telle qu'elle se trouve dans un plan supérieur (P1) au plan de la génératrice (P2) du tambour dans sa zone auto-agrippante concevant ainsi que, lors de la rotation du tambour, la bobine, partiellement en contact avec ledit doigt, provoque alors un effet de soulèvement de la bobine de matériau permettant son réajustement en position de non inclinaison et donc parfaitement parallèle à l'axe du tambour. Le doigt de soulèvement est établi pour permettre un soulèvement ponctuel de la bobine suffisant pour autoriser sa remise en place et positionnement. La largeur de la zone lisse (3g) entre les deux parties auto-agrippantes (3a) du tambour est telle également qu'il n'y a aucun contact avec la bobine de matériau avec aucun effet de retenue ou de freinage.The device for controlling and repositioning the material reel according to the invention is designed in the following manner. One (3d) of the lateral discs of the drum, advantageously the one arranged on the right side of the apparatus corresponding to the noted lower inclination portion of the material coil, has, directly by molding or inserting, a zone of thickness projecting from finger shape (12) which can be in contact with the material reel (b) once per revolution of rotation of the drum. Furthermore, the drum has, opposite the positioning of said finger (12), a smooth zone (3g) breaking with the gripping zone (3a). The drawings are shown in such an arrangement. The protruding position of the finger (12) is such that it lies in an upper plane (P1) in the plane of the generatrix (P2) of the drum in its self-gripping zone thus conceiving that, during the rotation of the drum, the coil, partially in contact with said finger, then causes a lifting effect of the material reel allowing its readjustment in non-inclination position and therefore perfectly parallel to the axis of the drum. The lifting finger is established to allow a timely raising of the coil sufficient to allow its refitting and positioning. The width of the smooth zone (3g) between the two self-gripping parts (3a) of the drum is also such that there is no contact with the material reel with no retaining or braking effect.

Dans l'hypothèse où le tambour est plein, la zone lisse est établie sur toute la longueur dudit tambour, sa largeur est supérieure à la largeur du doigt de soulèvement. En variante où le tambour présente des ouvertures ou évidements décrits dans le brevet FR 2656601 la zone lisse est établie dans la partie correspondante à la surface en regard du doigt de soulèvement.In the event that the drum is full, the smooth zone is established over the entire length of said drum, its width is greater than the width of the lifting finger. In a variant where the drum has openings or recesses described in the patent FR 2656601 the smooth zone is established in the part corresponding to the surface facing the lifting finger.

Il y a lieu également de considérer que ledit doigt de soulèvement se situe, dans un plan sensiblement opposé, à l'endroit de sortie de la lame de coupe, et ce après découpe de la bande de matériau. On comprend ainsi qu'il y a un réajustement automatique à chaque tour de la position de la bobine de matériau répondant au problème posé et évitant toute intervention sur le bouton de chargement.It should also be considered that said lifting finger is located in a substantially opposite plane, at the output of the cutting blade, and after cutting the web of material. It is thus understood that there is an automatic readjustment at each turn of the position of the material reel responding to the problem and avoiding any intervention on the loading button.

La solution apportée par l'invention est simple à réaliser et ne nécessite aucune pièce complémentaire.The solution provided by the invention is simple to make and requires no additional part.
