Description

APPAREIL DISTRIBUTEUR DE MATERIAU DΕSSUYAGE ET PAPIER TOILETTE A FONCTIONNEMENT AUTOMATIQUE OU SEMI- AUTOMATIQUE. APPARATUS FOR DISPENSING WIPING MATERIAL AND TOILET PAPER WITH AUTOMATIC OR SEMI-AUTOMATIC OPERATION.
L'invention se rattache au secteur technique des appareils de distribution de papier d'essuyage, en ouate de cellulose, papier crêpé, ou matériau similaire destiné plus particulièrement à l'essuyage des mains des utilisateurs, et papier toilette.The invention relates to the technical sector of devices for dispensing wiping paper, cellulose wadding, crepe paper, or similar material intended more particularly for wiping the hands of users, and toilet paper.
Il existe de très nombreux appareils d'essuyage en fonctionnement automatique, et le Demandeur a développé plusieurs appareils de ce type à fonctionnement automatique ou semi-automatique permettant la distribution de bandes de matériau pliées ou non pliées.There are many wiping devices in automatic operation, and the Applicant has developed several devices of this type with automatic or semi-automatic operation allowing the distribution of folded or unfolded strips of material.
Ces appareils, qui font l'objet d'exploitations 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 associé à l'axe de la lame de coupe, et coopérant avec un moyen à crémaillère positionné fixement et intérieurement sur l'une des ailes du carter. Ce tambour est associé par ailleurs à un mécanisme de lancement avec excentrique et ressort de rappel décrit et illustré dans le brevet français du Demandeur. Un couvercle assure la protection des mécanismes. On connaît par le Brevet US 4441392 l'agencement du tambour dans un appareil distributeur de coupe avec des points en saillie disposés aux extrémités du tambour pour permettre le décollage du papier lors de la rotation du tambour, et faciliter la coupe. 2These devices, which are the subject of satisfactory operations, are of the type comprising a molded casing, of plastic material, receiving in the upper part a reel for supplying wiping material, a drum containing a cutting device with a serrated blade. , as well as a pressing means ensuring the feeding of the strip of paper towards the drum and the tensioning of the paper. The cutting blade is articulated in the drum being set in motion by the cooperation of a toothed heel associated with the axis of the cutting blade, and cooperating with a rack means positioned fixedly and internally on one of the wings. of the housing. This drum is also associated with a launching mechanism with eccentric and return spring described and illustrated in the Applicant's French patent. A cover protects the mechanisms. The patent US 4441392 discloses the arrangement of the drum in a cutting dispensing apparatus with projecting points arranged at the ends of the drum to allow the paper to take off during rotation of the drum, and to facilitate cutting. 2
On connaît également par le brevet français n° 2555975 au nom du demandeur l'agencement du tambour sur sa périphérie avec des saillies en forme de pointes ou picots d'accrochage destinés à éviter le glissement l'une par rapport à l'autre des bandes libres de papier tirées sur deux rouleaux à la fois.Also known from French patent n ° 2555975 in the name of the applicant is the arrangement of the drum on its periphery with protrusions in the form of hooking points or pins intended to prevent the bands from sliding relative to each other. of paper drawn on two rolls at a time.
Si ces appareils du type précité, qui sont exploités très largement, ont un fonctionnement très fiable pour des papiers d'essuyage issus de fabrication nouvelle, on rencontre par contre certaines difficultés de coupe pour les papiers recyclés, pour les papiers de large épaisseur non plies, pour les papiers plies qui comprennent plusieurs épaisseurs se juxtaposant.If these devices of the aforementioned type, which are widely used, have a very reliable operation for wiping papers from new manufacturing, there are on the other hand certain cutting difficulties for recycled papers, for very thick unfolded papers. , for folded papers which include several thicknesses juxtaposed.
Cela est dû au fait que la mise en tension du papier avant la coupe n'est pas toujours constante en fonction de la nature et des caractéristiques du matériau, des conditions de traction de l'extrémité de la bande de papier par l'utilisateur.This is due to the fact that the tensioning of the paper before cutting is not always constant depending on the nature and characteristics of the material, the conditions of traction of the end of the strip of paper by the user.
Le Demandeur s'est donc intéressé à résoudre ce problème en essayant tout d'abord d'améliorer les conditions de pression du moyen presseur sur le tambour, en recherchant le tarage le plus approprié des moyens de rappel élastique.The Applicant is therefore interested in solving this problem by first trying to improve the pressure conditions of the pressing means on the drum, by seeking the most appropriate calibration of the elastic return means.
En pratique, les résultats étant peu constants, le Demandeur s'est orienté d'une manière imprévue sur les conditions de fonctionnement du tambour récepteur du dispositif de coupe.In practice, the results being inconsistent, the Applicant unexpectedly turned to the operating conditions of the receiving drum of the cutting device.
Ainsi, selon l'invention, l'originalité a consisté à modifier la section circulaire constante initiale du tambour par une variation de son profil extérieur sur une partie de sa périphérie, pour qu'il puisse agir dans certaines phases de fonctionnement de l'appareil et de distribution de coupe d'une bande de papier en assurant la meilleure tension possible de celle-ci. Selon l'invention, le tambour présente sur un secteur angulaire de sa périphérie une zone en surépaisseur définie entre le bord de l'ouverture de passage de la lame de coupe et une ligne correspondant au plan axial d'extrémité de l'axe de liaison et d'accrochage en bout de l'excentrique permettant le lancement du tambour en vue de la coupe, ladite zone d'épaisseur complémentaire étant en contact avec le moyen presseur sensiblement escamotable en position selon un montage flottant pour absorber les modifications de 1 'épaisseur du tambour lors de la phase de traction de la bande de papier étirée, puis de la coupe dudit papier.Thus, according to the invention, the originality consisted in modifying the initial constant circular section of the drum by a variation of its external profile over a part of its periphery, so that it can act in certain operating phases of the device. and cutting distribution of a strip of paper ensuring the best possible tension thereof. According to the invention, the drum has on an angular sector of its periphery a zone in excess thickness defined between the edge of the opening of passage of the cutting blade and a line corresponding to the axial end plane of the connecting axis and hooking at the end of the eccentric allowing the drum to be launched with a view to cutting, said zone of additional thickness being in contact with the presser means substantially retractable in position in a floating assembly to absorb changes in thickness of the drum during the phase of traction of the stretched paper strip, then of the cutting of said paper.
Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These characteristics and others will become apparent from the following description.

Afin de rendre plus concret l'objet de l'invention, on le décrit de manière non limitative illustrée aux figures des dessins. L'appareil selon l'invention incluant le tambour perfectionné et le montage flottant du moyen presseur sur le tambour, contribuant à assurer une mise en tension constante de la bande de matériau d'essuyage, est adapté pour la distribution de la coupe automatique ou semi-automatique de matériau d'essuyage en tout matériau approprié, ouate de cellulose, papier crêpé et similaire, en situation pliée ou non pliée, pour l'essuyage des mains ou la distribution de papier toilette.In order to make the object of the invention more concrete, it is described in a nonlimiting manner illustrated in the figures of the drawings. The apparatus according to the invention including the improved drum and the floating mounting of the pressing means on the drum, helping to ensure constant tensioning of the strip of wiping material, is suitable for the distribution of the automatic or semi cutting -automatic wiping material in any suitable material, cellulose wadding, crepe paper and the like, in a folded or unfolded situation, for wiping hands or dispensing toilet paper.
On rappelle rapidement et succinctement la conception d'un appareil distributeur pour essuie-mains et papier toilette référencé dans son ensemble par (1).We quickly and succinctly recall the design of a dispenser for hand towels and toilet paper referenced as a whole by (1).
Il 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 maintenu entre des flasques (4) supérieurs rapportés à montage rapide sur le fond du carter ou autrement.It comprises a casing (2) molded in plastic material capable of receiving in its upper part a coil (3) for supplying wiping material or toilet paper held between upper flanges (4) attached to quick mounting on the bottom of the casing or otherwise.
Des flasques inférieurs (5) sont rapportés et fixés à montage rapide ou autrement, sur la face de fond (2a) du carter et sont aménagés avec des échancrures (5a) autorisant la fixation et le montage rapide du tambour (6) incluant son dispositif de coupe (7) à lame dentelée (7a). Ledit dispositif de coupe est articulé, de la manière décrite précédemment, avec un mécanisme à talon (8) dentelé associé à la lame de coupe qui coopère avec une crémaillère fixe (9) établie sur le flanc intérieur (5b) de l'un des flasques (5) du carter. Le tambour présente une ouverture longitudinale (6f) permettant le passage et la sortie de la lame de coupe.Lower flanges (5) are attached and fixed for quick mounting or otherwise, on the bottom face (2a) of the casing and are fitted with notches (5a) allowing the fastening and quick mounting of the drum (6) including its device cutting (7) with serrated blade (7a). Said cutting device is articulated, as described above, with a serrated heel mechanism (8) associated with the cutting blade which cooperates with a fixed rack (9) established on the inner flank (5b) of one of the flanges (5) of the housing. The drum has a longitudinal opening (6f) allowing the passage and exit of the cutting blade.
Le tambour est agencé de manière connue correspondant à l'enseignement du brevet français no. 7604664 Une extrémité est positionnée et centrée sur l'un des flasques du carter (5), tandis que l'autre extrémité présente un axe (6a) en 5The drum is arranged in a known manner corresponding to the teaching of French patent no. 7604664 One end is positioned and centered on one of the flanges of the housing (5), while the other end has an axis (6a) in 5
débordement extérieur de l'autre flasque en s 'engageant et s 'ancrant dans une échancrure (5a) correspondante dudit flasque.external overflow of the other flange by engaging and anchoring in a notch (5a) corresponding to said flange.
Ledit axe (6a) présente une forme en excentrique (6b) dont l'extrémité (6c) formant doigt constitue le point d'attachement d'une extrémité (10a) d'un ressort de rappel et de lancement (10) , ce dernier ayant son autre extrémité (10b) fixée au carter à l'arrière du flasque (5) en regard. Un moyen presseur (11) sous forme de cylindre est de longueur correspondant à celle du tambour, et est susceptible d'être en appui sur celui-ci en étant positionné entre les flasques (5) précités. Comme illustré à la figure 2 des dessins, l'appareil distributeur ainsi connu peut être agencé accessoirement mais non obligatoirement avec un dispositif anti-retour (12) de la bande de matériau d'essuyage, comprenant ainsi un galet (13) en appui sur la bobine de matériau d'essuyage, ce galet étant positionné entre les flasques (5) du carter sur un levier coudé (14) assujetti à un moyen de rappel élastique (15) fixé aux flasques (5) du carter. Une courroie (16) est susceptible d'entourer le tambour (6) et le galet anti boucle.Said axis (6a) has an eccentric shape (6b) whose end (6c) forming a finger constitutes the point of attachment of one end (10a) of a return and launch spring (10), the latter having its other end (10b) fixed to the casing at the rear of the flange (5) opposite. A pressing means (11) in the form of a cylinder is of length corresponding to that of the drum, and is capable of being supported thereon by being positioned between the abovementioned flanges (5). As illustrated in FIG. 2 of the drawings, the dispensing device thus known can be arranged incidentally but not necessarily with a non-return device (12) of the strip of wiping material, thus comprising a roller (13) resting on the reel of wiping material, this roller being positioned between the flanges (5) of the casing on a bent lever (14) secured to an elastic return means (15) fixed to the flanges (5) of the casing. A belt (16) is capable of surrounding the drum (6) and the anti-loop roller.
Il convient dès lors d'exposer l'invention. Le tambour (6) qui est constitué sous forme d'un cylindre, creux par exemple présente sur une partie de sa périphérie extérieure et selon un secteur angulaire (α) déterminé, une zone de renflement (17) continue qui a pour but d'être dans certaines phases de fonctionnement de l'appareil en contact avec le moyen presseur (11), en sollicitant le déplacement de ce dernier selon un montage flottant par rapport à des ouvertures (18) ovalisées réceptrices formées sur les flasques (5) des extrémités du moyen presseur (1 1). Cette zone en surépaisseur (17) continue peut être de l'ordre de 0,7 mm à 1 ,5 mm en fonction des besoins. En se référant à la figure 3 illustrant l'appareil en phase de non fonctionnement la zone en surépaisseur est établie entre le bord (19) de l'ouverture longitudinale (6f) de passage de la lame de coupe du 6It is therefore necessary to expose the invention. The drum (6) which is formed in the form of a hollow cylinder, for example present on a part of its outer periphery and according to a determined angular sector (α), a continuous bulge zone (17) which has the purpose of be in certain operating phases of the device in contact with the pressing means (11), by requesting the displacement of the latter in a floating arrangement with respect to receptive oval openings (18) formed on the end plates (5) presser means (1 1). This continuous oversized area (17) can be of the order of 0.7 mm to 1.5 mm depending on requirements. Referring to FIG. 3 illustrating the appliance in the non-operating phase, the extra thickness zone is established between the edge (19) of the longitudinal opening (6f) for the passage of the cutting blade. 6

Cette zone de surépaisseur (17) peut être constituée par une paroi rapportée établie ou directement formée sur toute la longueur (α) du tambour dans le secteur considéré.cutting device and a line AA materializing a plane between the connecting axis (6a) for hooking at the end of the eccentric (6b) and the return and launching spring (10), with an angular sector (α) on the order of 120 ° to 130 °. This extra thickness zone (17) can be constituted by an attached wall established or directly formed over the entire length (α) of the drum in the sector considered.
On a représenté à la figure 1 des dessins un exemple de réalisation d'un tambour (6) qui comprend à partir de son arbre central (6d) une pluralité de disques radiaux (6e), permettant ainsi un allégement dudit tambour. Dans ce cas, la paroi (17) de surépaisseur se prolonge comme représenté aux dessins sur une partie de la périphérie (6e 1) des disques (6e) radiaux jusqu'à venir sensiblement dans le plan axial de la ligne AA décrite précédemment. Pour la compréhension des dessins, on a enlevé le revêtement accrocheur (toile émeri) recouvrant en partie le tambour.There is shown in Figure 1 of the drawings an exemplary embodiment of a drum (6) which comprises from its central shaft (6d) a plurality of radial discs (6e), thus allowing relief of said drum. In this case, the extra thickness wall (17) is extended as shown in the drawings over a part of the periphery (6th 1) of the radial discs (6th) until it comes substantially in the axial plane of the line AA described above. To understand the drawings, the eye-catching covering (emery cloth) partially covering the drum was removed.
Ainsi, selon l'invention, le secteur angulaire (α)correspondant à cette zone en surépaisseur est de l'ordre de 1 10 à 140°.Thus, according to the invention, the angular sector (α) corresponding to this area in excess thickness is of the order of 1 10 to 140 °.
Selon une autre disposition complémentaire de l'invention, les ouvertures réalisées (18) sur les flasques et permettant la réception du moyen presseur (11) sont ovalisées pour permettre un montage libre et flottant dudit moyen presseur (11). La profondeur de ces ouvertures ovalisées est telle qu'elles absorbent le déplacement du moyen presseur (1 1) en contact avec le tambour (6) lorsque ledit moyen presseur (11) est en appui et roulement sur la zone en surépaisseur établie sur ledit tambour.According to another complementary arrangement of the invention, the openings made (18) on the flanges and allowing the reception of the pressing means (11) are ovalized to allow free and floating mounting of said pressing means (11). The depth of these ovalized openings is such that they absorb the displacement of the pressing means (1 1) in contact with the drum (6) when said pressing means (11) is in bearing and rolling on the area in excess thickness established on said drum .
Avantageusement, lesdits flasques (5) peuvent être agencés avec plusieurs couples (18) de lumières ou trous ovalisés, pour permettre un positionnement de tambours de diamètres différents. Il y a lieu maintenant de se référer aux figures 3,4 et 5 des dessins qui illustrent d'une manière schématique la rotation du tambour (6) lors de l'effet de tirage de l'extrémité de la bande (B) de matériau par l'utilisateur et ainsi la coupe de la bande de papier selon le format pré-établi.Advantageously, said flanges (5) can be arranged with several pairs (18) of lights or ovalized holes, to allow positioning of drums of different diameters. Reference should now be made to Figures 3,4 and 5 of the drawings which schematically illustrate the rotation of the drum (6) during the pulling effect of the end of the strip (B) of material by the user and thus the cutting of the paper strip according to the pre-established format.
Selon la figure 3 correspondant à la phase initiale de non fonctionnement, la zone en surépaisseur (17) du tambour se trouve en position basse de celui-ci sans contact avec le moyen presseur (1 1) .According to Figure 3 corresponding to the initial phase of non-operation, the area in excess thickness (17) of the drum is in the low position of the latter without contact with the pressing means (1 1).
A la figure 4, selon la flèche (F) la traction de l'extrémité de la bande de papier a provoqué partiellement la rotation du tambour (6) et la mise en contact du moyen presseur (11) avec la zone en surépaisseur (17) tandis que la lame de coupeIn FIG. 4, according to the arrow (F), the pulling of the end of the paper strip partially caused the rotation of the drum (6) and the contacting of the pressing means (11) with the area in excess thickness (17 ) while the cutting blade
(7a) vient affleurer la bande de papier tendue située en sortie de la zone de contact et d'appui du moyen presseur (11) et du tambour (6).(7a) is flush with the stretched strip of paper located at the outlet of the contact and support area of the pressing means (11) and of the drum (6).
La figure 5 correspond à la phase de lancement maximum du tambour (6)avec effet de retour, correspondant à la situation dans laquelle le ressort (10) associé à l'excentrique (6b) est en position de sollicitation maximum. Dans cette phase, la lame de coupe (7a) est en position sortie en phase de coupe, tandis que le moyen presseur (11) est en contact avec la fin de la zone en surépaisseur (17) établie sur le tambour (6).Figure 5 corresponds to the maximum launch phase of the drum (6) with return effect, corresponding to the situation in which the spring (10) associated with the eccentric (6b) is in the position of maximum stress. In this phase, the cutting blade (7a) is in the extended position during the cutting phase, while the pressing means (11) is in contact with the end of the extra thickness zone (17) established on the drum (6).
Le mode de fonctionnement ainsi décrit permet de mettre en valeur l'effet recherché à la base de l'invention, à savoir une tension constante exercée sur la bande de papier étirée en phase de distribution puis de coupe. Après le passage du secteur la suppression de cette pression permet la sortie très librement de la bande de matériau sans aucun freinage. L'invention permet ainsi d'utiliser le tambour (6) perfectionné et le montage flottant du moyen presseur (11) pour autoriser la coupe de tout matériau d'essuyage ou papier toilette plié ou non plié et en toute matière.The operating mode thus described makes it possible to enhance the effect sought at the basis of the invention, namely a constant tension exerted on the stretched paper strip during the distribution and then cutting phase. After the passage of the sector, the removal of this pressure allows the strip of material to exit very freely without any braking. The invention thus makes it possible to use the improved drum (6) and the floating mounting of the pressing means (11) to authorize the cutting of any folded or unfolded wiping material or toilet paper and of any material.
Les caractéristiques intérieures du tambour sont quelconques. L'exemple représenté à la figure 1 des dessins est illustré comme une possible exécution.. L'orignalité réside dans la formation sur un secteur angulaire (α) de la périphérie dudit tambour d'une zone d'épaisseur (17) sur un secteur correspondant sensiblement à la mise en contact de la lame de coupe avec la bande de papier d'essuyage à découper après l'appui entre le moyen presseur et le tambour jusqu'à la phase finale de la coupe.The interior characteristics of the drum are arbitrary. The example shown in Figure 1 of the drawings is illustrated as a possible execution. The originality lies in the formation on an angular sector (α) of the periphery of said drum of a thick zone (17) on a sector substantially corresponding to the contacting of the cutting blade with the strip of wiping paper to be cut after pressing between the pressing means and the drum until the final phase of cutting.
Les avantages ressortent bien de la description. The advantages are apparent from the description.
