Description

L'invention se rattache au secteur technique des appareils distributeurs de matériau d'essuyage du type papier ouaté pour des applications essuie-mains, papier toilette, essuyage et nettoyage en général.The invention relates to the technical sector of devices dispensers for wiping paper-type wiping material for hand towel, toilet paper, wiping and cleaning applications in general.

Le demandeur a développé de nombreux appareils de ce type qui comprennent, de manière usuelle, un carter, un capot, un tambour avec lame de coupe intégrée, ladite lame étant susceptible de sortir en fonctionnement grâce à des moyens de lancement et de rappel du tambour incluant un excentrique et un ressort de lancement de rappel disposés à partir d'un côté latéral du tambour. Des flasques latéraux du carter sont agencés pour supporter la bobine de matériau qui vient soit en appui direct sur le tambour selon l'enseignement du brevet FR 2.332.215, soit dans un plan au-dessus du tambour sans contact avec celui-ci, comme par exemple dans la réalisation décrite dans le brevet FR 99.13691. Dans cette mise en oeuvre spécifique, un rouleau presseur est susceptible d'assurer une pression de la bande de matériau à un endroit donné en complément d'une seconde zone de pression définie vers la zone de coupe de la bande de matériau au niveau du tambour.The applicant has developed numerous devices of this type which usually include a housing, a cover, a drum with blade integrated cutting, said blade being capable of coming out in operation by means of launching and recalling the drum including a eccentric and a return launch spring arranged from one side side of the drum. Side flanges of the housing are arranged to support the reel of material which comes either in direct support on the drum according to the teaching of patent FR 2,332,215, or in a plane above of the drum without contact with it, as for example in the realization described in patent FR 99.13691. In this implementation specific, a pressure roller is capable of ensuring a pressure of the strip of material at a given location in addition to a second area of defined pressure towards the cutting zone of the strip of material at the level of the drum.

Dans ce genre d'appareils, le chargement de la bande de matériau, c'est-à-dire la mise en place de la première bande de matériau contre le tambour de la bobine selon la première mise en oeuvre, ou entre le tambour et le rouleau presseur s'effectue à l'aide d'un bouton de chargement qui est disposé à partir d'un côté latéral du carter et dans le prolongement axial dudit tambour. In this kind of device, loading the strip of material, that is to say the placement of the first strip of material against the drum of the coil according to the first implementation, or between the drum and the pressure roller is made using a loading button which is arranged from a lateral side of the casing and in the axial extension of said drum.

Un premier problème posé réside dans la difficulté d'accès audit boítier de chargement lors de la mise en place de l'appareil dans certains sites. L'accès n'est pas toujours aisé et cela peut être une contrainte.A first problem posed lies in the difficulty of access to said audit. charging box when installing the device in some Site (s. Access is not always easy and this can be a constraint.

La solution de placer le bouton de chargement à partir de la face avant apparente de l'appareil sous la forme d'une molette pouvant être manipulée par l'opérateur est envisageable, mais la solution n'est pas en pratique réalisable par suite d'autres contraintes liées au fonctionnement de l'appareil distributeur, et en particulier la faible course de la molette entraínant en rotation très limitée le tambour sans contrôle des efforts de lancement et de retour du tambour.The solution of placing the loading button from the front visible front of the device in the form of a wheel which can be manipulated by the operator is possible, but the solution is not practice achievable as a result of other constraints related to the operation of the dispensing device, and in particular the short stroke of the dial causing the drum to rotate very limited without controlling the forces of drum launch and return.

La solution d'utilisation d'un levier de chargement basculant vers l'avant de l'appareil a été décrite dans le brevet FR 2.705.330, ledit levier étant agencé à une extrémité avec des moyens d'engrènement pour coopérer avec une pièce formant crémaillère disposée sur l'axe du tambour. Lesdits moyens permettent, par le basculement du levier, d'avoir un effet démultiplicateur suffisant pour autoriser la sortie de la bande de matériau hors de l'appareil. Cette mise en oeuvre nécessite cependant la réalisation spécifique d'un levier avec des formes particulières, tout en requérant des moyens complémentaires pour le contrôle de rotation du tambour lors de la sortie de la lame de coupe. Ainsi, la solution précitée reste coûteuse à mettre en oeuvre. En outre, le levier débordant largement de l'appareil, il est source d'accrochage et de gêne. The solution for using a loading lever tilting towards the front of the device has been described in patent FR 2,705,330, said lever being arranged at one end with engagement means for cooperating with a rack-forming part arranged on the axis of the drum. Said means allow, by tilting the lever, to have an effect reduction gear sufficient to allow the material strip to exit out of the device. However, this implementation requires the realization specific of a lever with particular shapes, while requiring additional means for controlling the rotation of the drum during the exit of the cutting blade. Thus, the aforementioned solution remains expensive to put in action. In addition, the lever extending well beyond the device, it is source hooking and embarrassment.

Le but recherché selon l'invention était donc de concevoir un appareil distributeur de matériaux d'essuyage qui ait à la fois un dispositif de chargement peu encombrant, d'accès et de manipulation aisée, tout en résolvant le problème du contrôle de la rotation du tambour lors de la phase de sortie de lame de coupe, mais aussi en anticipant et évitant les effets anti-retour dans l'hypothèse d'un effort de traction excessif par l'opérateur.The aim sought after according to the invention was therefore to design an apparatus distributor of wiping materials which has both a device for space-saving loading, easy access and handling, while solving the problem of controlling the rotation of the drum during the phase cutting blade output, but also by anticipating and avoiding the non-return effects in the event of an excessive tractive effort by the operator.

Un autre but recherché selon l'invention était de mettre en oeuvre une solution nouvelle, peu coûteuse et qui offre un fonctionnement de l'appareil très silencieux.Another aim sought after according to the invention was to implement a new, inexpensive solution that offers device operation very silent.

Ces buts et d'autres encore ressortiront bien de la suite de la description.These and other goals will emerge well from the rest of the description.

Selon une première caractéristique de l'invention, l'appareil distributeur de matériau d'essuyage du type comprenant un carter de fixation murale avec une paroi de fond, deux flasques latéraux, une paroi de base inclinée et un capot, lesdits flasques latéraux recevant à rotation libre les axes d'un tambour incluant une lame de coupe du dispositif de coupe qui est intégré dans ledit tambour et susceptible d'un mouvement de déplacement à l'extérieur du tambour grâce à un mécanisme de chargement incluant un excentrique, un ressort de rappel et de lancement associé à l'un des flasques du carter, est remarquable en ce qu'il comprend un dispositif de chargement de l'appareil assurant le contrôle de la rotation du tambour, ledit dispositif incluant une plaque profilée montée pivotante sur l'un des flasques du carter, cette plaque étant agencée avec des moyens formant logement permettant le positionnement temporaire d'un moyen basculant associé au tambour et un moyen profilé en saillie disposé sur le flasque, ladite plaque étant agencée avec une forme en saillie supérieure coopérant, d'une part, avec le moyen pour permettre le pivotement de la plaque et, d'autre part, pour constituer une butée limitant le retour en position de la plaque en fin de traction de la bande de matériau et de rotation du tambour.According to a first characteristic of the invention, the device wiping material dispenser of the type comprising a fixing casing wall with a back wall, two side panels, a base wall inclined and a cover, said lateral flanges receiving free rotation axes of a drum including a cutting blade of the cutting device which is integrated in said drum and capable of displacement movement at the outside of the drum thanks to a loading mechanism including a eccentric, a return and launch spring associated with one of the flanges of the casing, is remarkable in that it includes a loading device of the device ensuring the control of the rotation of the drum, said device including a profiled plate pivotally mounted on one of the flanges of the casing, this plate being arranged with means forming a housing allowing the temporary positioning of a tilting means associated with the drum and a protruding profiled means disposed on the flange, said plate being arranged with a cooperating upper projecting shape, on the one hand, with the means to allow the plate to pivot and, on the other hand, to constitute a stop limiting the return to position of the plate at the end of pull the strip of material and rotate the drum.

    • 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 described now in a nonlimiting manner illustrated in the figures of the drawings.

    Préalablement, il est précisé que le mécanisme de chargement et de réglage du contrôle en rotation du tambour, est susceptible de s'appliquer dans les deux variantes de mise en oeuvre de l'appareil distributeur rappelées précédemment, c'est-à-dire celle dans laquelle la bobine de matériau est en appui sur le tambour (BF 2.332.215), et celle où la bobine de matériau n'est pas en appui sur le tambour (BF 99.13691). On a représenté aux dessins la seconde variante à titre d'exemple non limitatif.Beforehand, it is specified that the loading and drum rotation control setting, may apply in the two implementation variants of the dispensing device recalled previously, that is to say the one in which the coil of material is supported on the drum (BF 2.332.215), and that where the coil material is not supported on the drum (BF 99.13691). We have shown in the drawings the second variant by way of nonlimiting example.

    L'appareil distributeur est référencé dans son ensemble par (A) et comprend, de manière connue, un carter de fixation murale (1) avec une paroi de fond (la), deux flasques latéraux (1b), une paroi de base inclinée (1c) et un capot (2). Les flasques latéraux reçoivent à rotation libre les axes (3a) d'un tambour (3) incluant une lame de coupe (4a) du dispositif de coupe (4) qui est intégré dans ledit tambour et susceptible d'un mouvement de déplacement à l'extérieur du tambour grâce à un mécanisme de chargement incluant un excentrique, un ressort de rappel et de lancement associé à l'un des flasques (1b) du carter. De manière connue aussi, ledit tambour (3) est associé à un rouleau de sécurité (8) disposé dans la partie basse de l'appareil en sortie de carter, en étant relié l'un à l'autre par une courroie de transmission (7) pénétrant dans des gorges aménagées (3c) - (8a) sur le tambour et sur le rouleau de sécurité. Cette courroie (7) assure notamment le guidage du matériau vers la sortie de l'appareil. La bobine de matériau (B) est montée entre les flasques fixes de l'appareil ou des flasques basculants comme décrits dans les brevets antérieurs du déposant.The dispensing device is referenced as a whole by (A) and comprises, in known manner, a wall fixing housing (1) with a bottom wall (la), two side flanges (1b), an inclined base wall (1c) and a cover (2). The lateral flanges receive the axes with free rotation (3a) of a drum (3) including a cutting blade (4a) of the device cup (4) which is integrated in said drum and capable of movement movement outside the drum thanks to a mechanism loading including an eccentric, a return and launch spring associated with one of the flanges (1b) of the casing. In a known manner also, said drum (3) is associated with a safety roller (8) arranged in the part bottom of the device at the outlet of the casing, by being connected to each other by a transmission belt (7) penetrating into fitted grooves (3c) - (8a) on the drum and on the safety roller. This belt (7) ensures in particular the guiding of the material towards the exit of the device. The reel of material (B) is mounted between the fixed flanges of the device or flanges tilting as described in the previous patents of the applicant.

    Le mécanisme de coupe connu en soi comprend une lame (4a) associée à un porte-lame (4b) articulée qui permet sa sortie du tambour dans la partie arrière de l'appareil lors de l'effet de traction de l'extrémité de la bande de matériau par l'utilisateur. Cette traction exercée, qui peut varier selon la force exercée par l'utilisateur, peut provoquer un effet de retour du tambour entraínant alors la formation d'une boucle de matériau.The cutting mechanism known per se comprises a blade (4a) associated with an articulated blade holder (4b) which allows it to exit the drum in the rear part of the device during the pulling effect of the end of the strip of material by the user. This traction exerted, which can vary depending on the force exerted by the user, can cause a return effect of the drum then causing the formation of a loop of material.

    Le dispositif objet de l'invention inclut un dispositif de chargement de l'appareil assurant le contrôle de la rotation du tambour.The device which is the subject of the invention includes a loading device of the device controlling the rotation of the drum.

    Ce dispositif comprend une plaque profilée (10) qui est montée pivotante sur l'un des flasques (1b) du carter. Cette plaque profilée (10) présente une portée tubulaire (10a) qui est susceptible de s'engager autour d'une portée (12) formée directement sur ledit flasque (1b), et autorisant elle-même l'insertion de l'extrémité (3a) de l'axe du tambour (3) précité. Cette plaque profilée (10) présente également une partie plane en forme de secteur angulaire (10b) de l'ordre de 70 à 100° et située perpendiculaire à l'axe du tambour, pour venir en regard du flasque ou flanc latéral (3d) de ce dernier. Sur ledit secteur (10b), est conformée une succession de logements (10c) décalés angulairement et séparés par des formes en saillies (10d) orientées vers l'extérieur, c'est-à-dire vers la partie d'extrémité supérieure du secteur. Ces formes en saillies (10d) adjacentes sont orientées angulairement, de manière à assurer une fonction de butée et de retenue d'un moyen (13) associé au tambour (3) lorsqu'il y a un effet de retour de ce dernier. Le nombre de logements (10c) est au minimum de deux avec trois formes en saillies (10d) réparties sur la zone correspondante du secteur angulaire précité. La profondeur desdits logements est telle qu'elle permet l'insertion et le maintien en position du moyen (13) précitée. Ledit secteur (10b) est également agencé, dans sa partie supérieure (10e) avec une saillie supplémentaire avantageusement en arc curviligne et coaxiale à la portée tubulaire (10a) formée sur la pièce précitée (10). Cette saillie en forme d'arc présente un chant (10f) dont la fonction apparaítra par la suite.This device comprises a profiled plate (10) which is mounted pivoting on one of the flanges (1b) of the housing. This profiled plate (10) has a tubular seat (10a) which is capable of engaging around a bearing (12) formed directly on said flange (1b), and allowing itself the insertion of the end (3a) of the axis of the drum (3) above. This profiled plate (10) also has a flat part in the form of angular sector (10b) of the order of 70 to 100 ° and located perpendicular to the axis of the drum, to come opposite the flange or lateral flank (3d) of this latest. On said sector (10b), is formed a succession of dwellings (10c) angularly offset and separated by protruding shapes (10d) oriented towards the outside, i.e. towards the upper end part of the sector. These adjacent protruding shapes (10d) are oriented angularly, so as to provide a stop and retaining function for a means (13) associated with the drum (3) when there is a return effect of this latest. The number of dwellings (10c) is at least two with three protruding shapes (10d) distributed over the corresponding area of the sector aforementioned angular. The depth of said housings is such that it allows inserting and holding the above-mentioned means (13) in position. Said sector (10b) is also arranged, in its upper part (10e) with a projection advantageously additional in curvilinear and coaxial arc within reach tubular (10a) formed on the aforementioned part (10). This arch-shaped projection presents a song (10f) whose function will appear later.

    Selon une autre disposition, ladite plaque profilée (10) permet autour de sa portée (10a) de recevoir un moyen de rappel (14) sous forme de ressort dont une extrémité (14a) est fixée sur le flasque en regard (1b) à partir d'une ouverture appropriée (15), tandis que l'autre extrémité (14b) dudit moyen de rappel est fixée sur la plaque (10) proprement dite formant secteur. Une rondelle de maintien (16) du moyen de rappel (14) est positionnée et clipsée en extrémité de la portée (10a) tubulaire de la plaque précitée.According to another arrangement, said profiled plate (10) allows around of its scope (10a) to receive a return means (14) in the form of spring, one end (14a) of which is fixed to the facing flange (1b) at from an appropriate opening (15), while the other end (14b) said return means is fixed to the plate (10) proper forming sector. A retaining washer (16) of the return means (14) is positioned and clipped at the end of the tubular surface (10a) of the plate cited above.

    Selon une autre disposition, le flasque (1b) du carter est aménagé pour recevoir, d'une manière fixe, une saillie profilée (17), coudée par exemple, et pouvant assurer une fonction de butée et de limitation de course de la plaque (10). La dite ouverture (15) se situe sous-jacente à ladite saillie. Celle-ci est située sensiblement au-dessus de la portée (12) formée sur le flasque (1a). According to another arrangement, the flange (1b) of the casing is arranged to receive, in a fixed manner, a profiled projection (17), bent by example, and capable of providing a stop and limit function travel of the plate (10). Said opening (15) is located underlying said protrusion. This is located substantially above the bearing surface (12) formed on the flange (1a).

    Le tambour (3) présente, en regard du dispositif précité, un flasque ou flanc latéral (3d) agencé avec un évidement permettant le positionnement et le basculement d'une barrette (13) articulée sur ledit flasque par un axe (19). Cette barrette est profilée à son extrémité libre pour former crochet (13a).The drum (3) has, opposite the above-mentioned device, a flange or lateral flank (3d) arranged with a recess allowing positioning and the tilting of a bar (13) articulated on said flange by an axis (19). This bar is profiled at its free end to form a hook (13a).

    Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.

    Lors de l'opération de traction de la bande de matériau par l'utilisateur, selon un effort normal, le tambour (3) est mis en rotation pour permettre le défilement de la bande de matériau. Lors de la rotation du tambour, la barrette (13) tend à prendre une position excentrée vers l'extérieur, de par le phénomène de force centrifuge. Cette barrette (13) qui forme crochet (13a) à son extrémité est susceptible de venir en appui sur l'arc curviligne (10e) formé sur le secteur angulaire de manière à l'entraíner en pivotement par contact entre la partie crochet (13a) et le chant (10f) en provoquant la mise en tension du moyen élastique (14). En fin de traction et passage du point mort du tambour après lancement, la barrette (13) associée bascule n'étant plus soumise à l'effet de la force centrifuge et vient s'engager dans un des logements (10c) formés sur le secteur angulaire (10b). L'échappement de la barrette (13) et son basculement libère alors la plaque profilée (10) qui, par effet de détente du ressort de rappel (14), reprend sa position initiale, l'arc curviligne (10e) venant en butée contre la saillie fixe (17) formée sur le flasque (1b) de l'appareil. Ladite barrette (13) associée au tambour est susceptible de venir successivement dans les différents logements formés sur le secteur angulaire, lors du chargement de l'appareil, en permettant ainsi d'assurer une sortie programmée et délimitée de la bande de matériau.During the pulling operation of the strip of material by the user, according to a normal effort, the drum (3) is rotated to allow the strip of material to run. When rotating the drum, the bar (13) tends to assume an eccentric position towards outside, due to the centrifugal force phenomenon. This bar (13) which hook shape (13a) at its end is capable of coming to bear on the curved arc (10th) formed on the angular sector so as to drive it in pivoting by contact between the hook part (13a) and the edge (10f) in causing the tensioning of the elastic means (14). At the end of traction and passage of the dead center of the drum after launch, the associated bar (13) rocker no longer subject to the effect of centrifugal force and engages in one of the housings (10c) formed on the angular sector (10b). The exhaust of the bar (13) and its tilting then releases the plate profile (10) which, by the relaxation effect of the return spring (14), resumes its initial position, the curvilinear arc (10th) coming into abutment against the fixed projection (17) formed on the flange (1b) of the device. Said bar (13) associated with the drum is likely to come successively in different housings formed on the angular sector, when the device is loaded, thereby ensuring a programmed and delimited exit from the tape of material.

    Le mécanisme de chargement de l'appareil inclut un ensemble de pignons qui sont notamment représentés figure 2 des dessins. Une molette (20) de chargement est ainsi montée sur un axe (21) solidaire du flasque de l'appareil. Cette molette est épaulée et présente une première couronne (20a) qui est susceptible de déborder sensiblement hors de l'appareil pour permettre sa manipulation par l'opérateur. Cette molette comprend axialement une deuxième couronne (20b) de diamètre plus réduit qui coopère avec un pignon (22) intermédiaire monté sur un axe (23) tournant sur le flasque (1b), ledit pignon intermédiaire (23) coopérant avec une couronne (24) dentée montée en bout de l'axe (3a) du tambour (3).The device's charging mechanism includes a set of pinions which are shown in particular in FIG. 2 of the drawings. A wheel (20) of loading is thus mounted on an axis (21) integral with the flange of the device. This wheel is shouldered and has a first crown (20a) which is likely to spill out of the device significantly to allow its manipulation by the operator. This wheel includes axially a second ring (20b) of smaller diameter which cooperates with an intermediate pinion (22) mounted on a rotating pin (23) on the flange (1b), said intermediate pinion (23) cooperating with a toothed crown (24) mounted at the end of the axis (3a) of the drum (3).

    On comprend ainsi que toute action sur la molette (20) de chargement provoque une rotation partielle du tambour (3). Il peut être nécessaire d'effectuer plusieurs opérations sur la molette pour permettre une sortie suffisante de la bande de matériau. A cet effet, la partie réceptrice des logements (10c) et des saillies (10d) formées sur le secteur angulaire permet, par le positionnement de la barrette (13) dans le ou les logements, de sauvegarder l'avance et sortie de bande de matériau, et d'exercer une nouvelle action si nécessaire sur la molette sans que le tambour revienne en position initiale qui pourrait entraíner le retour de la bande de matériau dans l'appareil.It is thus understood that any action on the wheel (20) of loading causes partial rotation of the drum (3). He can be necessary to perform several operations on the dial to allow sufficient exit of the material strip. To this end, the receiving party of housings (10c) and projections (10d) formed on the angular sector allows, by positioning the bar (13) in the housing or housings, to save the feed and exit of material web, and to exercise a new action if necessary on the wheel without the drum coming back in initial position which could cause the strip of material to return to the device.

    Le dispositif ainsi décrit selon l'invention est donc simple et particulièrement avantageux en ce qu'il permet un fonctionnement sans bruit de l'appareil, et surtout une sortie et chargement de bande de matériau systématiquement contrôlée et sauvegardée. Le nombre de zones crantées et logements formés sur le secteur angulaire, permet ainsi de faire varier la longueur de la bande de matériau sortant de l'appareil, en combinaison avec la rotation partielle de la molette.The device thus described according to the invention is therefore simple and particularly advantageous in that it allows noise-free operation of the device, and especially a material strip exit and loading systematically checked and saved. The number of notched areas and housings formed on the angular sector, thus makes it possible to vary the length of the strip of material leaving the device, in combination with partial rotation of the wheel.
