Description

L'invention concerne un dispositif de coupe de maté­riaux d'essuyage stockés dans un appareil assurant leur distri­bution automatique sous la forme d'une bande étroite pliée en accordéon.The invention relates to a device for cutting wiping materials stored in an apparatus ensuring their automatic distribution in the form of a narrow strip folded in accordion.

L'objet de l'invention se rattache au secteur tech­nique des appareils de distribution de matériaux d'essuyage du type papier, ouate, non tissés ou autres.The object of the invention relates to the technical sector of devices for dispensing wiping materials of the paper, wadding, non-woven or other type.

On connaît de nombreux appareils et dispositifs conçus pour distribuer automatiquement ou non des longueurs de matériaux d'essuyage dans les sanitaires publics ou privés.Many devices and devices are known which are designed to automatically or not distribute lengths of wiping material in public or private sanitary facilities.

Ces moyens utilisent des matériaux divers : papiers, ouates, non tissés, qui sont dotés d'un certain pouvoir d'ab­sorbtion. Pour des raisons essentiellement économiques, les matériaux employés sont de plus en plus fins et donc plus fragiles.These means use various materials: papers, wadding, nonwovens, which are endowed with a certain absorbing power. For essentially economic reasons, the materials used are becoming thinner and therefore more fragile.

Lorsqu'on veut mettre à la disposition de l'utilisa­teur un appareil permettant une distribution automatique de longueurs déterminées de ces types de matériaux par simple traction sur une partie débordante de l'appareil, comme c'est le cas pour les appareils ayant fait l'objet de protections par brevets et dont le déposant est également le titulaire, on comprend que, compte-tenu des résistances à la traction, aussi faibles soient-elles, et du fait que l'utilisateur a les mains mouillées, il peut arriver avec des matériaux très fragiles, de déchirer la bande tirée avant la fin de la distribution.When we want to make available to the user a device allowing automatic distribution of determined lengths of these types of materials by simple traction on an overhanging part of the device, as is the case with devices having made the subject to patent protection and of which the applicant is also the holder, it is understood that, taking into account the tensile strengths, as low as they are, and the fact that the user has wet hands, he can arrive with very fragile materials, to tear the strip pulled before the end of the distribution.

Pour remédier à cet inconvénient, le déposant à proposé selon les demandes 8805939 et 8807823, un appareil permettant de couper et de distribuer automatiquement des lon­gueurs de matériaux d'essuyage mêmes les plus fins sans risque de déchirement inopiné. Pour celà, il a été prévu des moyens combinés entre eux pour successivement plier en accordéon la bande déroulée, l'entraîner et la couper à longueur de manière automatique lorsqu'on tire sur l'extrémité pliée et débordante de l'appareil, en ayant ainsi dans la main une bande étroite et résistante qui se dépliera naturellement ensuite en offrant une surface d'essuyage suffisante.To remedy this drawback, the applicant has proposed, according to applications 8805939 and 8807823, an apparatus making it possible to cut and automatically distribute lengths of wiping material, even the finest, without risk of unexpected tearing. For this, provision has been made for combined means for successively folding the accordion strip unrolled, drag it and cut it to length automatically when the folded and protruding end of the device is pulled, thus having in the hand a narrow and resistant strip which will naturally unfold then offering a surface sufficient wiping.

Dans ce type d'appareil, le dispositif d'entraîne­ment et de coupe de la bande pliée monté sur une partie fixe ou dans une cassette interchangeable, répond bien au problème posé. Cependant, suivant le genre de matériau d'essuyage utili­sé, la coupe par pénétration et déchirement obtenue par une lame dentelée et l'action de pincement de deux mâchoires d'ap­pui et de contre-appui, peut être modifiée, c'est-à-dire que la bande pliée peut être coupée trop tôt et alors la bande suivan­te risque de ne pas déborder de l'appareil, ou trop tard ce qui peut entraîner un débordement excessif et un effort plus impor­tant de traction.In this type of device, the device for driving and cutting the folded strip mounted on a fixed part or in an interchangeable cassette, responds well to the problem posed. However, depending on the type of wiping material used, the cut by penetration and tearing obtained by a serrated blade and the pinching action of two jaws of support and counter-support, can be modified, that is to say -to say that the folded strip can be cut too early and then the next strip may not overflow from the device, or too late which can lead to excessive overflow and a greater tensile force.

Pour obtenir un détachement net et précis de la bande pliée lors de la traction sur la partie débordante de l'appareil, avec tous les genres de matériaux d'essuyage des plus fragiles aux plus résistants, avec les mains mouillées et suivant n'importe quelle direction en sortie de l'appareil, on a conçu le dispositif de coupe selon l'invention qui est dispo­sé entre les couples de roues dentées d'entraînement du maté­riau plié en amont par les saillies complémentaires orientées et espacées définies dans la demande N. 8805939.To obtain a clear and precise detachment of the folded strip when pulling on the projecting part of the device, with all kinds of wiping materials from the most fragile to the most resistant, with wet hands and according to any direction at the output of the device, the cutting device according to the invention has been designed which is arranged between the pairs of toothed wheels for driving the material folded upstream by the complementary oriented and spaced projections defined in application N. 8805939 .

Suivant une première caractéristique, le dispositif de coupe est constitué par deux lames métalliques profilées et à bord tranchant montées à articulation élastique entre les couples de roues dentées d'entraînement du matériau plié, en un point déterminé, pour que par rotation desdits couples, les lames se superposent progressivement d'une extrémité à l'autre au fur et à mesure de la rotation, en restant en contact perma­nent avec pression et en position sensiblement parallèle aux axes de rotation des couples de roues dentées pendant toute la durée de la coupe pour trancher par cisaillement la bande pliée du matériau introduite entre lesdits couples et entraînée par traction manuelle sur la bande débordant de l'appareil provo­quant la rotation des couples.According to a first characteristic, the cutting device is constituted by two profiled metal blades with a cutting edge mounted with elastic articulation between the pairs of toothed wheels for driving the folded material, at a determined point, so that by rotation of said couples, the blades are progressively superimposed from one end to the other as the rotation progresses, remaining in permanent contact with pressure and in position substantially parallel to the axes of rotation of the pairs of toothed wheels throughout the duration of the cut for shear the folded strip of the material introduced between said pairs and driven by manual traction on the strip projecting from the device causing the couples to rotate.

Selon une autre caractéristique, les lames métalli­ques sont maintenues en contact permanent et en position sen­siblement parallèle aux axes de rotation des couples de roues dentées, par un dispositif comprenant une biellette articulée élastiquement par rapport à l'un des couples de roues dentées à sa partie inférieure et conformée à son extrémité supérieure pour que,lorsque les lames sont face à face, une saillie formée sous la lame métallique solidaire de l'autre couple de roues dentées s'appuie sur cette extrémité profilée et provoque à la fois, le basculement de ladite biellette et le pivotement de ladite lame qui oblige ainsi,l'autre lame située au dessus, à pivoter également.According to another characteristic, the metal blades are maintained in permanent contact and in a position substantially parallel to the axes of rotation of the pairs of toothed wheels, by a device comprising a rod articulated elastically with respect to one of the pairs of toothed wheels in its part. lower and shaped at its upper end so that, when the blades are face to face, a projection formed under the metal blade integral with the other pair of toothed wheels rests on this profiled end and causes both the tilting of said link and the pivoting of said blade which thus forces, the other blade located above, to also pivot.

Une autre caractéristique se trouve dans le fait que la biellette articulée est positionnée de manière précise sur le couple de roues dentées et profilées à son extrémité supé­rieure, de telle sorte qu'elle soit en contact avec la saillie de la lame de poussée pendant toute la fraction de rotation correspondant à la superposition complète des lames d'une ex­trémité à l'autre de leur bord tranchant, et qu'elle échappe de ladite saillie pendant tout le reste de la rotation.Another feature is that the articulated link is precisely positioned on the pair of toothed wheels and profiled at its upper end, so that it is in contact with the projection of the thrust blade throughout the fraction of rotation corresponding to the complete superposition of the blades from one end to the other of their cutting edge, and that it escapes from said projection during all the rest of the rotation.

Selon d'autres caractéristiques, les lames ont des bords tranchants opposés l'un à l'autre et courbes dans la longueur des lames pour autoriser le cisaillement progressif et leurs axes de pivotement sont légèrement inclinés de manière inverse dans le sens transversal pour assurer le contact entre elles.According to other characteristics, the blades have sharp edges opposite to each other and curved in the length of the blades to allow progressive shearing and their pivot axes are slightly inclined inversely in the transverse direction to ensure the contact between them.

Ces caractéristiques et d'autres encore ressortiront de la description qui suit.These characteristics and others will emerge from the description which follows.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous forme non limitative de réalisa­tion illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is now described in nonlimiting form of embodiment illustrated in the figures of the drawings.

En se référant à la figure 1, on rappelle successi­vement les principaux composants de l'appareil illustré, étant entendu que le dispositif selon l'invention peut être combiné avec d'autres types d'appareils.Referring to Figure 1, we successively recall the main components of the illustrated device, it being understood that the device according to the invention can be combined with other types of devices.

L'appareil est constitué essentiellement d'un sup­port (A) de fixation par rapport à une surface quelconque, d'un élément (B) porte-bobine, d'un capot de fermeture (D) et d'une cassette interchangeable (E), portant tous les mécanismes néce­ssaires à l'entraînement et à la coupe des bandes précedemment pliées en accordéon par des saillies (G1-G2) établies complé­mentairement sur le support (A) et sur le porte-bobine (B) qui porte également un moyen (H) de renvoi et de conformation de la bande déroulée.The device consists essentially of a support (A) for fixing relative to any surface, of a reel holder element (B), of a closure cover (D) and of an interchangeable cassette (E ), carrying all the mechanisms necessary for driving and cutting the strips previously folded in accordion by projections (G1-G2) established additionally on the support (A) and on the spool holder (B) which also carries a means (H) of return and conformation of the strip unrolled.

La cassette (E) présente latéralement des rainures (E1) de guidage à coulissement sur des glissières équipant les parois du support (A) où elle est verrouillée de manière auto­matique et libérée par action manuelle.The cassette (E) laterally has grooves (E1) for sliding guide on slides fitted to the walls of the support (A) where it is locked automatically and released by manual action.

Entre les faces avant et arrière de la cassette, sont montés à rotation libre deux couples de roues dentées coaxiales (1-2) et (3-4) destinées au guidage et à l'entraîne­ment de la bande pliée en amont, et passant entre les deux couples. A l'arrière, les roues dentées de guidage (1-3) à denture complète ont un module inférieur à celui des roues dentées d'entrainement (2-4). De cette manière, les roues den­tées de guidage engrènent entre elles sans jeu, tandis que les roues dentées d'entrainement engrènent entre elles avec un jeu régulier permettant le passage sans coincement de la bande pliée.Between the front and rear faces of the cassette, two pairs of coaxial toothed wheels (1-2) and (3-4) are mounted for free rotation intended for guiding and driving the folded strip upstream, and passing between the two couples. At the rear, the guide toothed wheels (1-3) with full teeth have a lower module than that of the drive toothed wheels (2-4). In this way, the guide toothed wheels mesh with each other without play, while the drive toothed wheels mesh with each other with a regular play allowing the passage without jamming of the folded strip.

D'autre part, les roues dentées d'entrainement pré­sentent du côté extérieur une bordure arrondie facilitant l'en­gagement de la bande au chargement de l'appareil, tandis que l'intérieur des dents est de préférence à surface rugeuse, en particulier de part et d'autre d'entailles (2a-4a) de passage du dispositif de coupe, afin d'assurer l'entraînement sans glissement après la coupe de la bande détachée.On the other hand, the drive toothed wheels have a rounded edge on the outside facilitating the engagement of the band when loading the device, while the inside of the teeth is preferably with a rough surface, in particular on the and other notches (2a-4a) for passage of the cutting device, in order to ensure the drive without slipping after the cutting of the detached strip.

Afin d'ajuster de manière précise l'espace entre les roues dentées, (2-4) en fonction de l'épaisseur du matériau à distribuer, il est prévu un montage réglable d'au moins un des couples de roues dentées au niveau de son axe de rotation. Ce réglage peut être obtenu par tous moyens tels que basculement suivant plusieurs positions dudit couple par rapport aux faces de la cassette, montage de l'axe dans une ouverture ovalisée, ou bien encore, par utilisation de cassettes de couples de roues dentées à écartement différent.In order to precisely adjust the space between the toothed wheels, (2-4) according to the thickness of the material to be dispensed, provision is made for an adjustable mounting of at least one of the pairs of toothed wheels at the level of its axis of rotation. This adjustment can be obtained by any means such as tilting according to several positions of said torque relative to the faces of the cassette, mounting of the axis in an ovalized opening, or alternatively, by using cassettes of pairs of toothed wheels with different spacing. .

Le dispositif de coupe suivant l'invention est cons­titué de deux lames métalliques (5 et 6) articulées en (7 et 8) aux deux roues dentées de chaque couple et traversant les entailles (2a-4a) des roues (2-4). Le bord tranchant (5a-6a) de chaque lame est en forme de biseaux inversés et l'arête est courbe comme le montre la figure 3, c'est-à-dire que la distan­ce (x) de l'arête à l'axe de pivotement de chaque lame décroit progressivement depuis l'extrémité articulée sur les roues dentées (1-3) jusqu'à l'autre extrémité.The cutting device according to the invention consists of two metal blades (5 and 6) articulated at (7 and 8) to the two toothed wheels of each pair and passing through the notches (2a-4a) of the wheels (2-4). The cutting edge (5a-6a) of each blade is in the form of inverted bevels and the edge is curved as shown in Figure 3, that is to say that the distance (x) from the edge to the pivot axis of each blade gradually decreases from the hinged end on the gear wheels (1-3) to the other end.

A noter que les axes (a et b) de pivotement des lames (5 et 6) sont légèrement inclinés de manière inverse dans le sens transversal pour des raisons expliquées dans la suite de la description.Note that the pivot axes (a and b) of the blades (5 and 6) are slightly inclined inversely in the transverse direction for reasons explained in the following description.

Les lames sont positionnées entre les roues dentées de chaque couple de telle sorte que par rotation desdits cou­ples puissent se trouver face à face en léger décalage avec leurs arêtes tranchantes superposables.The blades are positioned between the toothed wheels of each pair so that by rotation of said pairs can be face to face in slight offset with their overlapping cutting edges.

La lame (5) est réliée, à son extrémité opposée au tranchant à la roue dentée (2) par un ressort (9) orienté pour rappeler ladite lame dans le sens de rotation de la roue dentée ; de la même façon, la lame (6) est rappelée par un ressort (10) et les deux lames s'appuient au repos sur le moyeu entre les roues dentées (3-4).The blade (5) is connected, at its end opposite the cutting edge to the toothed wheel (2) by a spring (9) oriented to return said blade in the direction of rotation of the toothed wheel; in the same way, the blade (6) is returned by a spring (10) and the two blades rest at rest on the hub between the toothed wheels (3-4).

Une biellette (11) est articulée en (12) près de son extrémité inférieure sur la roue dentée (3) en dessous de la lame (6) au repos. Son extrémité supérieure située immédia­tement sous la lame forme une empreinte en creux (11a) destinée à coopérer avec une saillie convexe (5b) de la lame (5) lorsque les deux lames arrivent face à face.A link (11) is articulated at (12) near its lower end on the toothed wheel (3) below the blade (6) at rest. Its upper end located immediately under the blade forms a hollow imprint (11a) intended to cooperate with a convex projection (5b) of the blade (5) when the two blades arrive face to face.

Un ressort (13) convenablement attaché à l'extrémité inférieure de la biellette et sur la roue dentée (3), rappelle élastiquement la biellette en butée contre un point d'arrêt (3a) de ladite roue dentée.A spring (13) suitably attached to the lower end of the link and on the toothed wheel (3) resiliently brings the link back into abutment against a stopping point (3a) of said toothed wheel.

On décrit maintenant le fonctionnement de l'appareil équipé du dispositif de coupe selon l'invention.We will now describe the operation of the device equipped with the cutting device according to the invention.

Au chargement de l'appareil, la bande de matériau est déroulée de la bobine montée sur son support (B), puis positionnée sur l'organe de renvoi et de conformation (H) et engagée derrière le support (B) dégagé de la partie fixe (A), jusqu'à ce que son extrémité libre déborde à la partie infé­rieure de l'appareil.When loading the device, the strip of material is unwound from the reel mounted on its support (B), then positioned on the return and shaping member (H) and engaged behind the support (B) released from the fixed part (A), until its free end projects beyond the lower part of the appliance.

On applique ensuite le support (B) contre la partie fixe (A) en amorçant ainsi le pliage de la bande par les sail­lies (G1-G2). Lorsqu'on tire manuellement sur l'extrémité dé­bordante, la bande pliée passe automatiquement entre les cou­ples de roues dentées (1-3) et (2-4) qui sont alors entraînés en rotation, en tendant un ressort (14) attaché aux extrémités d'excentriques (15) formés en bout des axes de rotation des couples de roues dentés et à l'extérieur des roues (1 et 3). Le ressort (14) est pré-tendu en position repos (figure 4) et les excentriques (15) sont orientés de telle sorte que le ressort soit en phase de rappel élastique lorsque les deux lames de coupe arrivent face à face. De cette manière, l'énergie emmaga­sinée par le ressort se libère pour s'ajouter à l'effort de traction manuelle afin de vaincre la résistance engendrée par la coupe du matériau.The support (B) is then applied against the fixed part (A), thereby initiating the folding of the strip by the projections (G1-G2). When manually pulling on the overhanging end, the folded strip automatically passes between the pairs of toothed wheels (1-3) and (2-4) which are then rotated, tensioning a spring (14) attached to the ends eccentrics (15) formed at the end of the axes of rotation of the pairs of toothed wheels and outside the wheels (1 and 3). The spring (14) is pretensioned in the rest position (Figure 4) and the eccentrics (15) are oriented so that the spring is in the elastic return phase when the two cutting blades come face to face. In this way, the energy stored by the spring is released to add to the manual tensile force in order to overcome the resistance generated by cutting the material.

Lorsque les deux lames sont face à face (figures 5 et 6), compte-tenu de leur montage sur les roues dentées, leur partie active est sensiblement parallèle à la ligne passant par les axes de rotation des roues dentées, et le tranchant de la lame (6) est en contact ou presque avec le tranchant de la lame (5) en étant prêts à se superposer à leur extrémité située du côté des roues dentées (1 et 3).When the two blades are face to face (Figures 5 and 6), taking into account their mounting on the toothed wheels, their active part is substantially parallel to the line passing through the axes of rotation of the toothed wheels, and the cutting edge of the blade (6) is in contact or almost with the edge of the blade (5) while being ready to be superimposed at their end situated on the side of the toothed wheels (1 and 3).

A cet instant, la saillie (5b) de la lame (5) s'appuie sur l'empreinte (11a) de la biellette (11) qui du fait de son point d'articulation (12) judicieusement calculé, pivote à l'encontre de son ressort (13) sous la poussée de la lame (5) entrainée en rotation par la traction manuelle sur la bande débordante. Ladite lame (5) ainsi butée par sa saillie (5b), reste alignée avec la ligne d'axes et soutient la lame (6) également entrainée ; le ressort de la lame (5) est taré pour assurer la pression sur la lame (6) pendant la coupe.At this instant, the projection (5b) of the blade (5) rests on the imprint (11a) of the rod (11) which, due to its judiciously calculated point of articulation (12), pivots with the against its spring (13) under the thrust of the blade (5) driven in rotation by manual traction on the overflowing strip. Said blade (5) thus abutted by its projection (5b), remains aligned with the line of axes and supports the blade (6) also driven; the blade spring (5) is calibrated to ensure pressure on the blade (6) during cutting.

Pendant cette phase, la bande pliée de matériau tirée manuellement est tranchée progressivement d'un bord à l'autre (figures 7 et 8) du fait du profil courbe des tran­chants des lames.During this phase, the folded strip of material pulled manually is cut gradually from one edge to the other (Figures 7 and 8) due to the curved profile of the cutting edges of the blades.

En pratique, le réglage et la configuration des lames est tel qu'en fait de coupe, il reste une épaisseur de matériau qui n'est pas coupée, cela afin que dans l'action manuelle de traction, la bande suivante soit également entraî­née entre les roues dentées pour déborder de l'appareil. La séparation complète s'opère ensuite tout naturellement par réaction en fin de traction lorsque les roues dentées entrai­nées également par le rappel du ressort (14), reprennent leur position de repos après qu'un cliquet (16) articulé élastique­ment sur la roue dentée (2), ait passé une saillie (17) formée sur le moyeu de la roue dentée et munie d'au moins un cran d'arrêt (17a) empêchant le retour en arrière des roues dentées.In practice, the adjustment and configuration of the blades is such that in terms of cutting, there remains a thickness of material which is not cut, so that in the manual traction action, the next strip is also driven between the gears to extend beyond the device. The complete separation then takes place quite naturally by reaction at the end of traction when the toothed wheels also driven by the return of the spring (14), return to their rest position after a pawl (16) articulated elastically on the toothed wheel ( 2), has passed a projection (17) formed on the hub of the toothed wheel and provided with at least one stop notch (17a) preventing the backward movement of the toothed wheels.

A noter que lorsque la bande tirée est coupée, les lames (5 et 6) sont sensiblement sur la ligne des axes de rotation des roues dentées (figure 7).Note that when the drawn strip is cut, the blades (5 and 6) are substantially on the line of the axes of rotation of the toothed wheels (Figure 7).

A ce moment, l'empreinte (11a) de la biellette (11) échappe de la saillie (5b) de la lame (5) qui peut alors pivo­ter en rappel élastique pour revenir à la position repos, tandis que la lame (6) qui n'est alors plus soutenue en fait de même (figure 9). La biellette (11) revient également en posi­tion de butée sur le point d'arrêt (3a). L'appareil est alors prêt pour opérer une nouvelle traction manuelle sur la bande suivante en débordement. A noter encore qu'un dégagement (18) est ménagé à l'arrière de la cassette pour recueillir éven­tuellement les déchets de matériaux d'essuyage qui peuvent alors être évacués par des ouvertures (19).At this time, the imprint (11a) of the link (11) escapes from the projection (5b) of the blade (5) which can then pivot in elastic return to return to the rest position, while the blade (6) which is then no longer supported in fact the same (Figure 9). The link (11) also returns to the stop position on the stop point (3a). The device is then ready to operate a new manual traction on the next strip overflowing. Note also that a clearance (18) is provided at the rear of the cassette to possibly collect the waste of wiping materials which can then be discharged through openings (19).

Les avantages ressortent bien de la description, on souligne notamment la coupe nette et précise de tous types de matériaux d'essuyage par les lames de coupe profilées agissant par cisaillement progressif.The advantages emerge clearly from the description, in particular the clear and precise cutting of all types of wiping materials is emphasized by the profiled cutting blades acting by progressive shearing.
