Description

L'invention se rattache au secteur technique des moyens de distribution de longueur déterminée de bandes enroulées sur bobine.The invention relates to the technical sector of the means of distribution of determined length of strips wound on a reel.

L'invention s'applique aux appareils de distribution et de coupe simultanée du papier, ouate ou matériau d'essuyage dans toutes applications d'essuie-mains ou de distribution de papier toilette.The invention applies to distribution and cutting devices simultaneous paper, wadding or wiping material in all applications hand towels or toilet paper dispensers.

Le Demandeur a développé de nombreux appareils distributeurs de ce type, qui ont notamment été définis dans le brevet européen 145 622.The Applicant has developed numerous dispensing devices of this type. type, which have in particular been defined in European patent 145 622.

Un appareil de ce type comprend un carter de configuration parallélépipédique, à l'intérieur duquel est disposé un tambour monté en rotation par rapport aux flasques latéraux du carter, ce tambour étant agencé pour recevoir intérieurement un mécanisme de coupe avec lame dentelée, susceptible de sortir de celui-ci selon un cycle donné, lors de la rotation du tambour résultant de la traction de la bande de papier par un utilisateur. Un dispositif de lancement et de rappel du tambour décrit dans le brevet antérieur du Demandeur, permet d'assurer une coupe franche de la bande de matériau.A device of this type includes a configuration casing rectangular, inside which is arranged a drum mounted in rotation with respect to the lateral flanges of the casing, this drum being arranged to receive internally a cutting mechanism with serrated blade, capable of coming out of it according to a given cycle, during the rotation of the drum resulting from the pulling the strip of paper by a user. A device for launching and recall of the drum described in the Applicant's prior patent, allows to ensure a clean cut of the strip of material.

La bobine de matériau disposée au dessus du tambour est maintenue par des flasques disposés à partir du carter de l'appareil, elle est susceptible de venir ou non en appui sur le tambour.The reel of material placed above the drum is held by flanges arranged from the casing of the device, it is likely to come or not pressing on the drum.

La bande de matériau à distribuer contourne ainsi par l'arrière le tambour, en vue d'être évacuée à travers une fente disposée dans la partie inférieure du carter. The strip of material to be dispensed thus bypasses the drum from the rear, in order to be evacuated through a slot arranged in the lower part of the casing.

Pour assurer une bonne trajectoire de sortie hors de l'appareil de la bande de papier ou matériau tirée par l'utilisateur, le Demandeur a prévu d'agencer le tambour avec une gorge de guidage et de logement d'une courroie sans fin de transmission, qui s'enroule elle-même sur un arbre, maintenu entre les côtés latéraux du carter, et disposé près de la zone d'ouverture et de sortie de la bande de papier au fond de l'appareil.To ensure a good exit trajectory out of the tape device of paper or material drawn by the user, the Applicant has planned to arrange the drum with a guide groove and housing an endless belt of transmission, which wraps itself on a tree, held between the sides sides of the casing, and located near the belt opening and exit area of paper at the bottom of the device.

Cet arbre présente également une gorge disposée en étroite relation et dans le même plan avec la gorge formée sur le tambour, de sorte que lors de la rotation du tambour en vue de la coupe, ladite courroie entraíne la rotation de l'arbre et le bon guidage de la bande de papier vers la sortie de l'appareil.This tree also has a groove arranged in close relation and in the same plane with the groove formed on the drum, so that during rotation of the drum for cutting, said belt causes the rotation of the shaft and the good guiding of the paper strip towards the exit of the device.

Les dispositions de ce type ont été décrites dans le brevet européen précité.Arrangements of this type have been described in the aforementioned European patent.

Si ces dispositions permettent un bon fonctionnement de l'appareil distributeur de bandes de papier, on constate néanmoins quelques inconvénients qui résultent des modalités de traction et de tirage de la bande de papier à la sortie de l'appareil distributeur par l'utilisateur.If these provisions allow the device to function properly distributor of paper strips, there are nevertheless some drawbacks which result from the methods of pulling and pulling the strip of paper at the exit dispenser by the user.

En effet, il est courant que l'utilisateur tende à tirer latéralement la bande de papier à droite ou à gauche, dans une position oblique, ce qui a pour effet de faire sortir la courroie de son logement défini par les gorges précitées et de freiner ainsi le fonctionnement de l'appareil en entraínant parfois le blocage de ce dernier par déchirure du papier.Indeed, it is common for the user to tend to pull the strip laterally of paper on the right or on the left, in an oblique position, which has the effect of remove the belt from its housing defined by the aforementioned grooves and slow down the operation of the device by sometimes causing the blocking of this last by tearing the paper.

Très souvent, la courroie a même tendance à s'échapper de son logement, ce qui est naturellement nuisible au bon fonctionnement de l'appareil distributeur. Very often, the belt even tends to escape from its housing, which is naturally harmful to the proper functioning of the dispensing device.

Pour remédier à ces inconvénients, une première solution a été d'augmenter la tension de la courroie pour éviter ainsi son échappement de son logement, par un maintien très ferme. Cette première solution a entraíné un inconvénient secondaire. Il est alors apparu que le mécanisme de lancement du tambour devenait dur à mettre en oeuvre en rotation, et l'on a rencontré des difficultés pour tirer le papier et de la bande de matériau en général, surtout lorsque la ou les mains de l'utilisateur étaient mouillées.To remedy these drawbacks, a first solution was increase the tension of the belt to avoid its escape of sound housing, by a very firm support. This first solution resulted in a secondary drawback. It then appeared that the mechanism for launching the drum was becoming hard to rotate, and we encountered difficulties in pulling the paper and strip of material in general especially when the user's hand or hands were wet.

Ainsi, une tension renforcée de la courroie n'est donc pas satisfaisante et rend l'appareil distributeur inutilisable.Thus, an increased tension of the belt is therefore not satisfactory and makes the dispenser unusable.

Une autre démarche a été d'augmenter le diamètre des bords de la gorge formée sur l'arbre, de manière à constituer ainsi une sorte de couloir tendant à éviter l'échappement de la partie de courroie en regard dans le cas de traction latérale du papier.Another step was to increase the diameter of the edges of the groove formed on the tree, so as to constitute a sort of corridor tending to avoid the escape of the opposite belt part in the case of traction side of the paper.

Cette solution n'est pas entièrement satisfaisante, car on constate en pratique que le papier est marqué en son milieu, très souvent se coupe en se déchirant en deux parties de part et d'autre de la zone médiane.This solution is not entirely satisfactory, as we note in practice that the paper is marked in the middle, very often cuts in tearing in two parts on either side of the middle zone.

La démarche du Demandeur a donc été de s'orienter vers une modification dans la liaison tambour/arbre de sécurité, qui réponde d'une manière satisfaisante aux problèmes posés, liés à la traction latérale par l'utilisateur de la bande de papier sortant de l'appareil, dans des conditions de traction et de force plus ou moins importantes, et ce pour éviter l'échappement de la courroie de sa zone de réception.The Applicant's approach was therefore to move towards a modification in the drum / safety shaft connection, which responds satisfactorily to the problems posed, linked to the lateral traction by the user of the web of paper coming out of the machine, under tensile and force conditions more or to reduce the escape of the belt from its area of reception.

Selon une première caractéristique de l'invention, le dispositif de contrôle et de sécurité permettant la sortie de la bande de matériau dans un appareil distributeur de bandes comprenant un tambour et un arbre de sécurité obturant l'ouverture inférieure de passage de la bande de matériaux en sortie de carter et de tambour, ledit tambour et ledit arbre étant reliés par un moyen de transmission constitué par une courroie est caractérisé en ce que ledit moyen de transmission est monté entre le tambour et l'arbre selon un montage flottant, l'arbre récepteur de ladite courroie étant aménagé dans sa partie centrale en regard de la gorge formée sur le tambour dans une configuration en diabolo, de dimension supérieure à la largeur de la gorge formée sur le tambour, de manière à permettre un débattement latéral en oblique de la courroie, en accompagnant, selon une amplitude limitée, ainsi le sens de traction longitudinal de la bande de papier par l'utilisateur hors du distributeur.According to a first characteristic of the invention, the control and security device enabling the strip of material to exit into a strip dispensing device comprising a drum and a safety shaft closing the lower opening for passage of the strip of materials at the outlet of the casing and of the drum, said drum and said shaft being connected by a transmission means constituted by a belt is characterized in that said transmission means is mounted between the drum and the shaft according to a floating assembly, the shaft receiver of said belt being arranged in its central part facing the groove formed on the drum in a diabolo configuration, of dimension greater than the width of the groove formed on the drum, so as to allow a lateral oblique movement of the belt, accompanying, according to a limited amplitude, the direction of longitudinal traction of the strip of paper by the user out from the distributor.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These characteristics and others will become clear from the rest of the description.

  • Figure 3 is a large-scale view of the shaft arranged according to the invention with a graphic representation of the position of the belt according to different forces of the front or side traction.

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.

L'appareil distributeur est référencé dans son ensemble par (1). Une mise en oeuvre particulière, non limitative, est décrite ci-après, permettant l'adaptation de l'invention.The dispensing device is referenced as a whole by (1). A bet in particular, non-limiting work, is described below, allowing the adaptation of the invention.

Il comprend un carter (2) à fixation murale présentant des côtés latéraux ou flasques (3) susceptibles de recevoir dans leur partie basse en rotation un tambour (4) creux intérieurement.It includes a wall-mounted housing (2) with lateral sides or flanges (3) capable of receiving in their lower part in rotation a drum (4) hollow internally.

Ce tambour est susceptible de recevoir un mécanisme de coupe (5) apte à sortir dudit tambour dans des conditions de rotation de ce dernier lors de la traction de la bande de papier en vue de la coupe de cette dernière.This drum is capable of receiving a cutting mechanism (5) capable of leave said drum under conditions of rotation of the latter during the pulling the strip of paper to cut it.

Le mécanisme de coupe peut être du type décrit dans les brevets du Demandeur.The cutting mechanism can be of the type described in the patents of Applicant.

Le tambour creux intérieurement présente ainsi une fente (4a) de passage du dispositif de coupe (5) en sortie de ce dernier.The hollow inner drum thus has a passage slot (4a) of the cutting device (5) at the outlet of the latter.

Latéralement et de manière connue, le tambour est susceptible de recevoir un mécanisme de lancement (7) du type décrit précédemment.Laterally and in a known manner, the drum is capable of receiving a launching mechanism (7) of the type described above.

La bande de matériau enroulée en bobine est montée entre des flasques (8) supérieurs, de sorte que ladite bobine vient avantageusement en appui sur le tambour.The strip of material wound on a reel is mounted between flanges (8) upper, so that said coil advantageously bears on the drum.

Un dispositif de contrôle et de sécurité constitué par un arbre (9), est disposé dans la partie inférieure du carter (2) sous-jacent au tambour (4) et près de l'ouverture (11) ou fente de passage établie dans le carter pour permettre la sortie de la bande de matériau (B). A control and safety device consisting of a shaft (9) is arranged in the lower part of the casing (2) underlying the drum (4) and close opening (11) or passage slot established in the housing to allow the material strip exit (B).

Ce dispositif de contrôle et de sécurité constitué par un arbre (9) est susceptible de permettre la réception d'une courroie d'entraínement (10) constituant le moyen de transmission qui empêche, d'une part, le passage inopiné des bandes de papier entre le tambour et l'arbre et, d'autre part, les oblige à se diriger vers l'ouverture inférieure de l'appareil.This control and safety device constituted by a shaft (9) is capable of allowing the reception of a drive belt (10) constituting the means of transmission which prevents, on the one hand, the unexpected passage strips of paper between the drum and the tree and, on the other hand, forces them to direct towards the lower opening of the appliance.

Le tambour (4) comprend ainsi une gorge (4b) dans sa partie médiane, susceptible de recevoir la courroie (10) en formant le chemin de glissement.The drum (4) thus comprises a groove (4b) in its middle part, capable of receiving the belt (10) by forming the sliding path.

L'invention réside dans le fait que l'arbre (9) présente, dans sa partie médiane et en regard de la gorge (4b) formée sur le tambour (4), une configuration en diabolo (9a) selon une réduction d'épaisseur (D1) par rapport à la section (D2) de l'arbre (9) , et constituant le logement de la courroie (10).The invention resides in the fact that the shaft (9) has, in its part median and opposite the groove (4b) formed on the drum (4), a diabolo configuration (9a) according to a reduction in thickness (D1) compared to the section (D2) of the shaft (9), and constituting the housing of the belt (10).

La longueur (L1) de cette configuration en diabolo est telle qu'elle déborde très largement de la largeur (L2) de la gorge formée sur le tambour, de sorte qu'elle permet, lors de l'effort de traction de la bande de papier par l'utilisateur, un mouvement latéral selon une amplitude α, en limitant le déplacement latéral de la courroie qui subit ainsi une déformation sensible lors de la traction de la bande de papier dans un plan latéral.The length (L1) of this diabolo configuration is such that it greatly exceeds the width (L2) of the groove formed on the drum, so that it allows, during the effort of traction of the strip of paper by the user, a lateral movement according to an amplitude α, limiting the lateral movement of the belt which undergoes significant deformation during pulling the strip of paper in a lateral plane.

Ladite courroie (10) est mise dans une tension telle qu'elle ait un montage flottant entre le tambour (4) et l'arbre de sécurité (9), pour assurer un débattement latéral en fonction des conditions de traction de la bande de papier.Said belt (10) is tensioned so that it has a mounting floating between the drum (4) and the safety shaft (9), to ensure travel lateral depending on the pulling conditions of the paper strip.

Avantageusement, la forme en diabolo (9a) de la partie de l'arbre précité, est arrêtée latéralement par les parois (9b) de l'arbre (9) formant ainsi épaulement et butée, de sorte que ladite courroie ne peut échapper de son logement. Cette courroie montée flottante dans le logement, reste néanmoins maintenue et en position extrême de placement contre l'une des parois intérieures de l'arbre, elle ne déborde pas et ne vient pas sur la périphérie extérieure (9c) de celui-ci.Advantageously, the diabolo shape (9a) of the part of the aforementioned tree, is stopped laterally by the walls (9b) of the shaft (9) thus forming a shoulder and stop, so that said belt can not escape from its housing. This belt mounted floating in the housing, remains nevertheless maintained and in extreme position of placement against one of the interior walls of the tree, it does not overflow and does not come on the outer periphery (9c) thereof.

Le montage ainsi réalisé flottant et limité en amplitude de la courroie de transmission entre le tambour et l'arbre de sécurité, permet d'utiliser l'appareil de distribution dans toutes les circonstances de traction latérale de la bande de matériau, sans qu'il y ait de blocage de l'appareil.The assembly thus produced floating and limited in amplitude of the belt transmission between the drum and the safety shaft, allows the use of the distribution under all circumstances of lateral traction of the material, without blocking the device.

Par ailleurs, accessoirement, la gorge (4a) formée sur le tambour peut présenter à l'endroit de sa fente formée sur celui-ci, de légères surépaisseurs (4b) pour assurer le contrôle de position de la courroie de transmission lors du débattement extrême de celle-ci dans le cas de son montage flottant le long de la forme en diabolo de l'arbre de sécurité.Furthermore, incidentally, the groove (4a) formed on the drum can present at the location of its slot formed thereon, slight excess thicknesses (4b) to check the position of the transmission belt when extreme displacement of the latter in the case of its floating assembly along the diabolo shape of the safety tree.

L'invention est applicable à tous types d'appareils distributeurs de bandes de matériau, incluant une liaison par moyen de transmission du type « courroie » entre le tambour récepteur d'un dispositif de coupe, et un arbre de sécurité disposé en partie inférieure du carter, assurant le guidage de sortie de la bande de matériau.The invention is applicable to all types of tape dispensing devices of material, including a connection by means of transmission of the “belt” type between the receiving drum of a cutting device, and a safety shaft disposed in the lower part of the casing, ensuring the exit guide of the strip of material.

Sans sortir de l'invention, on peut envisager également de doubler le nombre de moyens de transmission mettant en oeuvre l'invention. Dans ce cas là, le tambour est agencé avec un nombre de gorges correspondant au nombre de courroies de transmission, et en regard, l'arbre de sécurité présente un nombre de formes en diabolo identiques pour assurer le fonctionnement considéré.Without departing from the invention, it is also possible to envisage doubling the number of transmission means implementing the invention. In this case, the drum is arranged with a number of grooves corresponding to the number of transmission belts, and opposite, the safety shaft has a number of Identical diabolo shapes to ensure the functioning considered.

Les avantages ressortent bien de l'invention. The advantages emerge clearly from the invention.

On souligne la simplicité de mise en oeuvre de ce perfectionnement qui n'augmente pas les coûts de fabrication de l'appareil distributeur, et la grande fiabilité de celui-ci.The simplicity of implementing this improvement is emphasized. does not increase the manufacturing costs of the dispensing apparatus, and the large reliability of it.
