LONGUEUR DE MATÉRIAU DÉBITÉLENGTH OF MATERIAL DELIVERED
L'invention se rattache au secteur technique des appareils de distribution de papiers d'essuyage, en ouate de cellulose, papiers crêpés, ou matériaux similaires destinés plus particulièrement à l'essuyage des mains des utilisateurs, à la distribution de papier toilette, à la distribution de serviettes en papier. Ces papiers peuvent être sous forme pliée ou non pliée.The invention relates to the technical sector of devices for dispensing wiping paper, cellulose wadding, crepe paper, or similar materials intended more particularly for wiping the hands of users, for dispensing toilet paper, for distribution of paper towels. These papers can be in folded or unfolded form.
Le Demandeur a développé de nombreux brevets sur les appareils du type précité dans les versions automatique et semi-automatique de distribution de bande de papier en provenance d'une bobine de chargement.The Applicant has developed numerous patents on devices of the aforementioned type in the automatic and semi-automatic versions for dispensing paper webs from a loading reel.
On rappelle succinctement les caractéristiques d'un tel appareil cité à titre non limitatif.The characteristics of such a device cited without limitation are briefly recalled.
L'appareil est référencé dans son ensemble par (1) et comprend un carter (2), un couvercle (3), un tambour (4), un dispositif de coupe (5) intégré dans le tambour, un élément presseur (6) ainsi que des moyens de lancement et de rappel du tambour incluant un excentrique (7) et un ressort (8). Dans sa partie haute, le carter reçoit deux flasques (2a - 2b) susceptibles de recevoir un porte-bobine (9) ou des embouts support d'alimentation d'une bobine (B) de matériau d'essuyage. Le tambour (4) et l'élément presseur sont également maintenus entre des flasques inférieurs (2c - 2d) établis perpendiculairement par rapport au plan arrière (2e) du carter. Le tambour comprend un axe (4a) se prolongeant à ses extrémités pour former, d'une part et d'un côté, un bouton de manoeuvre et, d'autre part et de l'autre côté, au-delà du flasque récepteur (2c), un levier excentrique (7) susceptible de recevoir le ressort (8) de lancement et de rappel. L'ensemble tambour (4) - élément presseur (6) permet le passage et l'entraînement de la bande de papier derrière le tambour en vue de sa coupe, l'élément presseur étant en appui sur le tambour et l'ensemble tournant à la manière d'un engrenage en sens opposé. Un rouleau suiveur (10) peut être disposé dans la partie basse du carter ayant pour objet notamment, d'une manière connue, la protection des mains de l'utilisateur en se trouvant à l'endroit de sortie du papier hors de l'appareil, et le guidage de la sortie du papier. Ce rouleau suiveur est mis en mouvement à l'aide d'une courroie (11) associée au tambour.The device is referenced as a whole by (1) and comprises a casing (2), a cover (3), a drum (4), a cutting device (5) integrated in the drum, a pressing element (6) as well as means for launching and returning the drum including an eccentric (7) and a spring (8). In its upper part, the casing receives two flanges (2a - 2b) capable of receiving a reel holder (9) or end pieces supplying a reel (B) of wiping material. The drum (4) and the pressing element are also held between lower flanges (2c - 2d) established perpendicularly to the rear plane (2e) of the casing. The drum comprises an axis (4a) extending at its ends to form, on the one hand and on one side, an operating button and, on the other hand and on the other side, beyond the receiving flange (2c), an eccentric lever (7) capable of receiving the spring (8) for launching and returning. The drum unit (4) - pressing element (6) allows the passage and the entrainment of the paper strip behind the drum in view of its cutting, the pressing element being in abutment on the drum and the rotating assembly at the way of a gear in opposite direction. A follower roller (10) can be arranged in the lower part of the casing having, in particular, in a known manner, the protection of the user's hands by being at the point where the paper exits the device , and guiding the paper exit. This follower roller is set in motion using a belt (11) associated with the drum.
Dans tous ces types d'appareils, quelles qu'en soient leurs caractéristiques de construction, la bande de matériau qui est sortie à chaque tour de rotation du tambour, est établie sous un format fixe et définitif, par exemple de 10 pouces ou de 18 pouces ou autre. Si l'on veut modifier la longueur du format de chaque unité de papier découpé, il est nécessaire alors de changer de tambour afin qu'il ait un diamètre ou une circonférence correspondant à la longueur choisie dudit format pour un tour de rotation du tambour. Cela limite donc, d'une manière très conséquente, les conditions d'utilisation de l'appareil distributeur.In all these types of apparatus, whatever their construction characteristics, the strip of material which has come out at each rotation of the drum, is established in a fixed and definitive format, for example 10 inches or 18 inches or whatever. If you want to change the length of the format of each unit of cut paper, it is then necessary to change the drum so that it has a diameter or a circumference corresponding to the chosen length of said format for one rotation of the drum. This therefore limits, in a very consistent manner, the conditions of use of the dispensing device.
L'expérience a montré que, selon les marchés en Europe, aux Etats-Unis ou dans d'autres pays, les habitudes de consommation de papier étaient sensiblement différentes dans le domaine de l'essuyage que ce soit dans des applications de papier essuie-main, essuie-tout, papier-toilette et autres ou pour une même application. Il est donc pour l'instant nécessaire de réaliser des appareils distributeurs dont le tambour, qui est l'élément ou composant principal, doit être changé en fonction des conditions d'utilisation et de distribution du format de papier. Cela entraîne de ce fait des modifications dans les formes, les dimensions de l'appareil et de ses différents composants. A la connaissance du Demandeur et d'une manière générale pour l'ensemble des appareils distributeurs de matériau d'essuyage, aussi bien ceux du Demandeur que ceux de la concurrence, les appareils distributeurs sont limités à la distribution d'un format déterminé de la bande de matériau.Experience has shown that, depending on the markets in Europe, the United States or other countries, paper consumption habits are significantly different in the area of wiping, whether in paper towel applications. hand, paper towel, toilet paper and others or for the same application. It is therefore for the moment necessary to produce dispensing devices, the drum, which is the main element or component, must be changed according to the conditions of use and distribution of the paper size. This therefore results in changes in the shapes, dimensions of the device and its various components. To the knowledge of the Applicant and generally for all of the wiping material dispensing apparatuses, both those of the Applicant and those of the competition, the dispensing apparatuses are limited to the distribution of a determined format of the strip of material.
Il s'agit donc d'inconvénients importants allant à rencontre d'une standardisation de production des composants.These are therefore significant drawbacks which go against a standardization of production of the components.
On observe également qu'en fonction des applications des appareils distributeurs pour des essuie-mains, des essuie-tout, du papier-toilette, serviettes en papier, les longueurs de format de bande de papier sont bien différentes dans chacune d'elles. On rencontre donc également des problèmes de standardisation et il faut réaliser des appareils avec leurs composants adaptés à chaque application choisie.It is also observed that, depending on the applications of the dispensing apparatus for paper towels, paper towels, toilet paper, paper towels, the lengths of paper tape format are very different in each of them. There are therefore also problems of standardization and it is necessary to produce devices with their components adapted to each chosen application.
Le but recherché selon l'invention était donc de concevoir un nouveau tambour pour appareil distributeur de matériau d'essuyage, toutes applications considérées qui soit apte, sur un seul tour de rotation, à distribuer une bande de matériau d'essuyage selon un format variable.The aim sought after according to the invention was therefore to design a new drum for apparatus for dispensing wiping material, all applications considered, which is capable, on a single rotation, of dispensing a strip of wiping material in a variable format. .
Un autre but recherché selon l'invention était de concevoir un tambour qui soit apte, sur un tour de rotation correspondant à une sortie d'un format de matériau, à proposer une variation de longueur (α) couvrant toutes les plages de longueur de matériau en vue de couvrir toutes les applications des appareils distributeurs.Another aim sought after according to the invention was to design a drum which is capable, on a rotation turn corresponding to an output of a material format, of proposing a variation in length (α) covering all the ranges of length of material to cover all applications of dispensing devices.
Un autre but recherché selon l'invention a été de concevoir un nouveau tambour qui réponde aux problèmes posés mais qui soit d'un coût de fabrication faible et d'un montage rapide.Another aim sought after according to the invention has been to design a new drum which responds to the problems raised but which is of a low manufacturing cost and rapid assembly.
Ces buts et d'autres encore ressortiront bien de la suite de l'invention.These aims and others will emerge clearly from the rest of the invention.
Selon une première caractéristique de l'invention, le tambour est aménagé intérieurement avec des moyens permettant une variation programmée par un mécanisme sélecteur de la longueur du format de la bande de matériau à distribuer en obtenant des formats différents à partir de longueur minimum et maximum, et une amplitude différentielle.According to a first characteristic of the invention, the drum is fitted internally with means allowing a programmed variation by a mechanism for selecting the length of the format of the strip of material to be dispensed by obtaining different formats from minimum and maximum length, and a differential amplitude.

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.
Le tambour référencé dans son ensemble par (4) est utilisé dans un appareil de distribution de bande de matériau d'essuyage référencé dans son ensemble par (1). Ce tambour, d'une manière connue, participe à la distribution de la bande de matériau issue de la bobine (B) par le fait que la bande est mise en appui sur le tambour puis, grâce à l'intervention d'un moyen presseur (6) complémentaire, le tambour entraîne, par sa rotation, la bande de matériau. De manière connue également, le tambour est agencé pour recevoir un dispositif de coupe référencé dans son ensemble par (5). A titre d'exemple non limitatif, le tambour qui présente une cavité (4a) intérieure, reçoit à articulation le dispositif de coupe, dans les conditions par exemple qui ont été décrites dans le brevet français du Demandeur N. 2332215. La rotation du tambour sur un tour est obtenue par l'effet de traction du matériau par l'utilisateur hors de l'appareil, selon un format spécifique. L'objet de l'invention est donc d'agencer le tambour (4) avec un mécanisme permettant, après réglage et sélection, de faire varier la longueur du format du matériau distribué, selon les besoins, et obtenir des formats différents selon les longueurs (Ll) et (L2) (minimum et maximum), et une amplitude différentielle (α).The drum referenced as a whole by (4) is used in a device for dispensing a strip of wiping material referenced as a whole by (1). This drum, in a known manner, participates in the distribution of the strip of material from the reel (B) by the fact that the strip is pressed against the drum then, thanks to the intervention of a pressing means (6) complementary, the drum drives, by its rotation, the strip of material. Also in known manner, the drum is arranged to receive a cutting device referenced as a whole by (5). By way of nonlimiting example, the drum which has an interior cavity (4a), receives the cutting device with articulation, under the conditions for example which have been described in French patent of Applicant N. 2332215. The rotation of the drum on a lathe is obtained by the pulling effect of the material by the user outside the device, according to a specific format. The object of the invention is therefore to arrange the drum (4) with a mechanism making it possible, after adjustment and selection, to vary the length of the format of the material dispensed, as required, and to obtain different formats according to the lengths (L1) and (L2) (minimum and maximum), and a differential amplitude (α).
A cet effet, le tambour selon l'invention est agencé avec un mécanisme sélecteur réglable en position et permettant de faire varier la longueur du format de la bande de matériau en agissant d'une manièreTo this end, the drum according to the invention is arranged with a selector mechanism adjustable in position and making it possible to vary the length of the format of the strip of material by acting in a manner
10 spécifique pour obtenir en plus de la longueur (L) de la circonférence du tambour, un différentiel (α) complémentaire correspondant à l'augmentation ou à la réduction du format en longueur de la bande de matériau .10 specific to obtain in addition to the length (L) of the circumference of the drum, a complementary differential (α) corresponding to the increase or reduction of the format in length of the strip of material.

Il y a lieu maintenant de se référer à la mise en oeuvre spécifique de l'invention.It is now necessary to refer to the specific implementation of the invention.
Le tambour (4) est réalisé à partir de différents composants fabriqués „0 en matière plastique et qui sont assemblés entre eux par un montage rapide essentiellement à base d'emboîtements. Le tambour comprend tout d'abord un corps de base cylindrique (10) comprenant, à partir d'un disque central (10a) un arbre (10b) traversant disposé axialement et longitudinalement à l'axe du tambour, en débordant de part et d'autre du pc disque. L'arbre comprend ainsi deux demi-parties (lObl - 10b2) consécutives qui sont susceptibles de constituer une base d'introduction des deux flancs latéraux (11 - 12) du tambour. Ces derniers sont emmanchés et sont maintenus à l'arbre (10b) à l'aide d'une vis de liaison (13) ou similaire. Les deux demi-parties (lObl - 10b2) opposées de l'arbreThe drum (4) is made from various manufactured components "0 plastic material and which are interconnected by quick assembly essentially based on sockets. The drum firstly comprises a cylindrical base body (10) comprising, from a central disc (10a) a through shaft (10b) disposed axially and longitudinally to the axis of the drum, projecting from both sides and d other from the pc disk. The shaft thus comprises two consecutive half-parts (lObl - 10b2) which are capable of constituting a base for the introduction of the two lateral flanks (11 - 12) of the drum. The latter are fitted and are held on the shaft (10b) using a connecting screw (13) or the like. The two opposite half-parts (lObl - 10b2) of the shaft
30 sont de longueur différente pour tenir compte du montage des autres composants du tambour. Afin d'assurer de parfaits centrages et orientations des flancs latéraux (11 - 12) du tambour (4) sur le corps de base (10), il est prévu d'établir, sur chacun des flancs latéraux et de leur portée cylindrique (lia - 12a) en particulier, des échancrures (11b - 12b) permettant l'engagement de tenons (14) de forme complémentaire établis sur les pièces en regard.30 are of different length to take account of the mounting of the other components of the drum. In order to ensure perfect centering and orientation of the lateral flanks (11 - 12) of the drum (4) on the base body (10), provision is made to establish, on each of the lateral flanks and their cylindrical bearing (lia - 12a) in particular, notches (11b - 12b) allowing the engagement of studs (14) of complementary shape established on the facing pieces.
Un premier flanc latéral (11) comprend ainsi, d'une manière monobloc obtenue par moulage, une forme en cuvette circulaire (lie) prolongée intérieurement par un manchon (lia) de petite longueur s'adaptant sur la demi-partie (lObl) de l'arbre du corps de base et extérieurement avec un doigt de centrage (15) prolongé par un profil en came formant excentrique (16) pour s'adapter sur le flasque (2c) fixe de l'appareil distributeur. Ce flanc (11) est agencé par exemple avec une découpe (lld) pour permettre le passage, l'orientation du dispositif de coupe (5) établi par exemple sous forme d'un portique avec lame dentelée.A first lateral flank (11) thus comprises, in a monobloc manner obtained by molding, a circular bowl shape (lie) extended internally by a sleeve (lia) of short length fitting on the half-part (lObl) of the shaft of the base body and externally with a centering finger (15) extended by a cam profile forming an eccentric (16) to adapt to the fixed flange (2c) of the dispensing device. This sidewall (11) is arranged for example with a cutout (lld) to allow passage, the orientation of the cutting device (5) established for example in the form of a gantry with serrated blade.
Le deuxième flanc latéral (12) opposé du tambour comprend une forme en cuvette monobloc (12c) avec, côté intérieur, un manchon (12a) de grande longueur s'adaptant sur la demi-partie (10b2) de l'arbre du corps de base (10) et présentant extérieurement un prolongement permettant la formation et la réalisation du bouton de manoeuvre (12d).The second opposite lateral flank (12) of the drum comprises a one-piece cup shape (12c) with, on the inside, a long sleeve (12a) fitting onto the half-part (10b2) of the body shaft. base (10) and externally having an extension allowing the formation and the production of the operating button (12d).
Selon l'invention, le corps de base comprend, sur un premier côté, une paroi (lOd) profilée établie sur une partie de la circonférence du tambour et sur une partie de l'intervalle existant entre le disque (10a) du corps de base (10) et le flanc (11) latéral en regard. Cette paroi périphérique (lOd) est établie sur une circonférence d'environ 300 à 330 degrés pour laisser le passage et l'articulation du portique support de lame de coupe (5). Cette paroi périphérique (lOd) sera susceptible de recevoir une bande caoutchouteuse (16) formant courroie. Cette dernière est montée, comme représentée figure 2 des dessins, dans une configuration en haricot de sorte à entourer la partie d'arbre (lObl) correspondante du corps de base.According to the invention, the base body comprises, on a first side, a profiled wall (10d) established on a part of the circumference of the drum and on a part of the gap existing between the disc (10a) of the base body (10) and the side flank (11) opposite. This peripheral wall (10d) is established on a circumference of approximately 300 to 330 degrees to allow passage and the articulation of the gantry supporting the cutting blade (5). This peripheral wall (10d) will be able to receive a rubber band (16) forming a belt. The latter is mounted, as shown in Figure 2 of the drawings, in a bean configuration so as to surround the corresponding shaft part (lObl) of the base body.
L'autre face (lOf) du corps de base (10), côté bouton de manoeuvre (12c), est agencée avec une première barrette (10g) perpendiculaire à la paroi discale (10a) et débordant axialement sur une certaine longueur, ainsi qu'une deuxième barrette (lOh) espacée de la première et d'une longueur similaire. Ces deux barrettes (10g - lOh) sont avantageusement disposées de part et d'autre de l'échancrure (e) du tambour, laissant le passage à la lame de coupe (5). Une butée (17) est conformée sur la paroi discale (10a) corps de base (10) à un endroit approprié. Avantageusement, l'arbre (10b) du corps de base reçoit directement par moulage ou d'une manière rapportée une portée (19) cylindrique mais excentrée par rapport à la demi-partie (10b2) de l'arbre et venant en butée par une face (19a) contre la paroi discale du corps de base et présentant sur l'autre face, une portée de centrage (19b) dont la fonction sera précisée par la suite.The other face (10f) of the base body (10), on the operating button side (12c), is arranged with a first bar (10g) perpendicular to the disc wall (10a) and projecting axially over a certain length, as well as 'a second bar (10h) spaced from the first and of a similar length. These two bars (10g - 10h) are advantageously arranged on either side of the notch (e) of the drum, allowing passage to the cutting blade (5). A stop (17) is formed on the disc wall (10a) base body (10) at a suitable location. Advantageously, the shaft (10b) of the base body receives directly by molding or in a reported manner a bearing (19) cylindrical but eccentric with respect to the half-part (10b2) of the shaft and coming into abutment by a face (19a) against the disc wall of the base body and having on the other face, a centering surface (19b) whose function will be explained below.
La paroi discale (10a) du corps de base présente une perforation (10m) dans son épaisseur pour permettre le positionnement d'un moyen de rappel (18) du type ressort à hélice ainsi qu'il sera précisé par la suite. A la suite de la portée cylindrique excentrée (19) précitée, est positionnée une pièce cylindrique (20) dont les formes sont très particulières et qui vient s'emmancher par une portée (20a) sur la demi-partie (10b2) de l'arbre (10b) du corps de base (10). Cette pièce (20) est maintenue à positionnement par la partie manchon (12a) du flanc latéral (12) adjacent du tambour. Cette pièce (20) est agencée sur sa partie extérieure avec des zones d'appui (20b - 20c) curvilignes destinées à permettre le passage à positionnement et appui du papier ou matériau d'essuyage. Ces deux zones d'appui (20b - 20c) sont situées de part et d'autre de la zone d'échancrure (e) du tambour (4) réceptrice de l'organe de coupe (5). Ces zones d'appui ont un profil établi sur une partie seulement de la circonférence du tambour. La première zone d'appui (20b) est agencée pour recevoir un cliquet de verrouillage (21) basculant articulé par rapport à un axe (22) intégré dans la partie d'appui précitée. Cette dernière présente en outre des fentes (20d - 20e) ou des découpes permettant le positionnement du cliquet établi dans une configuration générale en U.The disc wall (10a) of the base body has a perforation (10m) in its thickness to allow the positioning of a return means (18) of the helical spring type as will be explained later. Following the above-mentioned eccentric cylindrical seat (19), a cylindrical part (20) is positioned, the shapes of which are very specific and which is fitted by a seat (20a) on the half-part (10b2) of the shaft (10b) of the base body (10). This part (20) is held in position by the sleeve part (12a) of the lateral flank (12) adjacent to the drum. This part (20) is arranged on its outer part with curvilinear support zones (20b - 20c) intended to allow the passage or positioning of the paper or wiping material. These two support zones (20b - 20c) are located on either side of the notch zone (e) of the drum (4) receiving the cutting member (5). These support zones have a profile established over only part of the circumference of the drum. The first support zone (20b) is arranged to receive a tilting locking pawl (21) articulated with respect to an axis (22) integrated in the abovementioned support part. The latter also has slots (20d - 20e) or cutouts allowing the positioning of the pawl established in a general U-shaped configuration.
Ainsi, il est formé entre la paroi discale (10a) du corps de base (10) et le disque annulaire (20f) de la pièce d'appui (20), une chambre intérieure radiale (23) permettant l'insertion d'un mécanisme original particulier permettant de faire varier la longueur du format de bande de matériau, distribuée par le tambour de l'appareil. Ainsi, le mécanisme comprend une roue dentée (24) disposée et montée libre autour de la collerette (19b) de la portée excentrée établie sur l'arbre du corps de base, ladite roue dentée venant en regard du cliquet de verrouillage (21). Cette roue présente, sur sa périphérie, une multitude de dents (24a) consécutives séparées par des fentes (24b), les dents étant marquées par des références (24c) chiffrées par exemple en définissant des longueurs de pas. Cette roue dentée (24) est donc susceptible de recevoir, dans une fente (24b) entre ses dents, le cliquet (21) en définissant ainsi un positionnement particulier pour une longueur de format particulière de la bande de papier. Cette roue dentée reçoit intérieurement une saillie (24d) formant butée dont l'intérêt sera précisé par la suite. Cette roue dentée assure donc la fonction d'un sélecteur de format. Adjacente à cette roue dentée, est positionnée une bague de distribution (25) profilée montée sur la portée excentrée de l'arbre du corps de base. A cet effet, la bague de distribution comprend un alésage (25a) en contact avec la portée excentrée précitée en étant montée libre à rotation. Cette bague de distribution comprend un disque intérieur (25b) formant paroi médiane définissant de part et d'autre deux chambres (25c - 25d) ou cavités, l'une (25c) en regard de la roue dentée (24), l'autre (25d) en regard du corps de base. La première chambre (25c) est par ailleurs agencée avec une butée (26) susceptible de coopérer dans certaines conditions avec la patte en saillie (24d) formée sur la roue dentée (24). L'autre chambre (25d) est susceptible de recevoir le ressort de rappel (18). La première extrémité (18a) de ce ressort est introduite dans l'orifice (10m) de la paroi discale du corps de base. L'autre extrémité (18b) du ressort est introduite dans l'épaisseur (25e) du disque médian de la bague de distribution. Cette bague de distribution reçoit par ailleurs sur sa périphérie une bande (27) caoutchouteuse susceptible de constituer une zone d'appui du matériau. La bague est ainsi montée avec une excentration de sorte qu'elle se trouve dans un plan sensiblement déportée vers l'extérieur par rapport aux zones d'appui du matériau formées sur les autres pièces composantes du tambour.Thus, there is formed between the disc wall (10a) of the base body (10) and the annular disc (20f) of the support piece (20), a radial inner chamber (23) allowing the insertion of a special original mechanism for varying the length of the material strip format, distributed by the device drum. Thus, the mechanism comprises a toothed wheel (24) disposed and mounted freely around the flange (19b) of the eccentric bearing established on the shaft of the base body, said toothed wheel coming opposite the locking pawl (21). This wheel has, on its periphery, a multitude of consecutive teeth (24a) separated by slots (24b), the teeth being marked by references (24c) encrypted for example by defining pitch lengths. This toothed wheel (24) is therefore capable of receiving, in a slot (24b) between its teeth, the pawl (21) thereby defining a particular positioning for a particular format length of the paper strip. This toothed wheel internally receives a projection (24d) forming a stop whose interest will be explained later. This toothed wheel therefore performs the function of a format selector. Adjacent to this toothed wheel, is positioned a profiled distribution ring (25) mounted on the eccentric bearing of the shaft of the basic body. To this end, the distribution ring comprises a bore (25a) in contact with the above-mentioned eccentric bearing while being mounted free to rotate. This distribution ring includes an inner disc (25b) forming a median wall defining on either side two chambers (25c - 25d) or cavities, one (25c) facing the toothed wheel (24), the other (25d) opposite the base body. The first chamber (25c) is also arranged with a stop (26) capable of cooperating in certain conditions with the protruding tab (24d) formed on the toothed wheel (24). The other chamber (25d) is capable of receiving the return spring (18). The first end (18a) of this spring is introduced into the orifice (10m) of the disc wall of the base body. The other end (18b) of the spring is introduced into the thickness (25e) of the median disc of the distribution ring. This distribution ring also receives on its periphery a rubber band (27) capable of constituting a support zone for the material. The ring is thus mounted with an eccentricity so that it lies in a plane substantially offset towards the outside with respect to the bearing zones of the material formed on the other component parts of the drum.
La bague de distribution est donc mise en rotation à rencontre de la déformation élastique du ressort de rappel pouvant créer un effet de retour par détente élastique de ce dernier.The distribution ring is therefore rotated against the elastic deformation of the return spring which can create a return effect by elastic relaxation of the latter.
Il y a lieu de noter que le support de lame, lorsqu'il est relevé, permet facilement l'accès manuel en vue du réglage de la roue dentée formant sélecteur.It should be noted that the blade support, when raised, allows easy manual access for adjusting the gear wheel forming the selector.
Selon une disposition importante de l'invention, il est prévu des moyens qui limitent la rotation angulaire de la roue dentée par rapport à la pièce cylindrique (20) afin de définir un réglage de la course entre une position minimum et une position maximum correspondant à la variation (α) de la longueur du format de matériau à distribuer. Ces moyens empêchent à la roue dentée de devenir une roue folle empêchant alors tout réglage du format choisi. Pour ce faire, la roue dentée comprend une rainure circulaire (24e) établie sur une partie simplement de la circonférence de la roue dans l'épaisseur de celle-ci, de façon à définir des zones de butée (24f - 24g) correspondant à des positions minimum et maximum. Une butée (20g) en saillie formée sur la pièce cylindrique (20) en débordement extérieur de la paroi discale en regard de la roue dentée est susceptible de pénétrer dans la rainure circulaire (24e) formée sur cette dernière. Ainsi, la rotation de la roue dentée est limitée angulairement sur environ 300 à 340 degrés puisque la partie en saillie (20g) bloque en position la roue dentée.According to an important arrangement of the invention, means are provided which limit the angular rotation of the toothed wheel relative to the cylindrical part (20) in order to define an adjustment of the stroke between a minimum position and a maximum position corresponding to the variation (α) in the length of the format of material to be dispensed. These means prevent the toothed wheel from becoming a mad wheel then preventing any adjustment of the chosen format. To do this, the toothed wheel comprises a circular groove (24e) established on a part simply of the circumference of the wheel in the thickness of the latter, so as to define abutment zones (24f - 24g) corresponding to minimum positions and maximum. A projecting stop (20g) formed on the cylindrical part (20) projecting outside the disc wall opposite the toothed wheel is capable of penetrating into the circular groove (24e) formed on the latter. Thus, the rotation of the toothed wheel is angularly limited to around 300 to 340 degrees since the projecting part (20g) locks the toothed wheel in position.
u a été indiqué, dans la description, que la roue dentée présentait une indexation en pouces. Il est évident néanmoins que toute autre mesure de référence est possible, et notamment en système métrique.u was indicated, in the description, that the toothed wheel had an indexing in inches. It is obvious, however, that any other reference measurement is possible, and in particular in the metric system.
Ainsi que représenté figure 10, la pièce cylindrique (20) est agencée sur son axe avec un bossage excentré (20m) susceptible de permettre l'emmanchement approprié de la pièce sur le corps de base. Un ensemble à rainurage et tenon permet la liaison et l'assemblage de la pièce cylindrique (20) sur le corps de base (10).As shown in Figure 10, the cylindrical part (20) is arranged on its axis with an eccentric boss (20m) capable of allowing the appropriate fitting of the part on the base body. A grooving and tenon assembly allows the connection and assembly of the cylindrical part (20) on the base body (10).
La bague de distribution (25) comprend également dans sa chambre (25b), une saillie (25g) susceptible de coopérer avec la butée (17) formée sur le corps de base (10).The distribution ring (25) also comprises in its chamber (25b), a projection (25g) capable of cooperating with the stop (17) formed on the base body (10).
Il convient maintenant, en se reportant aux figures des dessins, d'expliquer le fonctionnement de l'invention.It is now appropriate, with reference to the figures of the drawings, to explain the operation of the invention.
La bague de distribution (25) est montée libre en pivotement rotatif à rencontre du ressort de rappel (18). La roue dentée (24) qui lui est associée est positionnée par rapport à un point de repérage qui est avantageusement établi sur la base d'ancrage du cliquet (21) dans la roue dentée. Ainsi, le chiffre qui apparaît sur la dent de la roue dentée sous-jacente au cliquet correspond à l'indication de longueur du format du matériau à distribuer et à couper. Dans l'exemple où le format de matériau est d'une longueur minimum, par exemple 10 pouces, correspondant à la circonférence du tambour, la rotation de celui-ci, à travers la mise en contact de la bague (25) de distribution avec le matériau, va provoquer la rotation de celle-ci jusqu'à ce que la butée (26) formée dans la chambre intérieure (25c) vienne en contact avec le doigt de butée (24 d) ou saillie formé sur la roue dentée.The distribution ring (25) is mounted to rotate freely against the return spring (18). The gear (24) associated therewith is positioned with respect to a locating point which is advantageously established on the base for anchoring the pawl (21) in the gear. Thus, the figure which appears on the tooth of the toothed wheel underlying the pawl corresponds to the length indication of the format of the material to be distributed and cut. In the example where the format of material is of a minimum length, for example 10 inches, corresponding to the circumference of the drum, the rotation of the latter, through contacting the distribution ring (25) with the material, will cause the rotation of the latter until the stop (26) formed in the inner chamber (25c) comes into contact with the stop finger (24 d) or projection formed on the toothed wheel.
Dans cette position, le cliquet verrouille la roue dentée dans l'échancrure formée sur la dent repérée (10 pouces), et on distribue une bande du format minimum.In this position, the pawl locks the toothed wheel in the notch formed on the marked tooth (10 inches), and a strip of the minimum size is distributed.
Lorsque l'opérateur veut modifier la longueur du format de matériau à distribuer, il procède au déverrouillage du cliquet (21) et on tourne la roue dentée (24) dans la position choisie de sélection de longueur de format. Il peut donc manoeuvrer, sans difficulté, la roue dentée par une action partielle de rotation, selon l'angle souhaité correspondant par exemple à une variation de distance angulaire établie entre 10 et 18 pouces. Lorsque la longueur a été choisie, il bascule le cliquet sur la roue dentée assurant son blocage en position, de sorte que la saillie (24d) qui lui est associée est orientée angulairement dans la chambre (25c) de la bague de distribution. L'opérateur peut alors utiliser l'appareil distributeur en tirant la bande de matériau.When the operator wants to modify the length of the format of material to be dispensed, he proceeds to unlock the pawl (21) and the toothed wheel (24) is turned to the selected position for selecting the format length. It can therefore maneuver, without difficulty, the toothed wheel by a partial action of rotation, according to the desired angle corresponding for example to a variation of angular distance established between 10 and 18 inches. When the length has been chosen, it rocks the pawl on the toothed wheel ensuring its locking in position, so that the projection (24d) associated therewith is angularly oriented in the chamber (25c) of the distribution ring. The operator can then use the dispensing device by pulling the strip of material.
Selon l'invention, en phase initiale, le rouleau presseur (6) est en appui sur la bague de distribution excentrée, le tambour étant immobile. Quand on tire sur le papier, on fait tourner la bague de distribution et l'élément presseur. On obtient ainsi le différentiel de longueur qui a été programmé sur la roue dentée formant sélecteur. Lorsque la bague de distribution vient en butée sur le tambour, on entraîne le tambour et on permet la sortie continue du matériau. Dès que le tambour, par ses parois (lOd - 20c), est en contact avec la bande de matériau et non plus avec la bague de distribution, celle-ci est libérée et revient au point zéro par l'effet de rappel donné par le ressort intérieur (18), déroulant ainsi la bande de matériau d'une longueur complémentaire.According to the invention, in the initial phase, the pressure roller (6) is supported on the eccentric distribution ring, the drum being stationary. When you pull on the paper, you rotate the dispensing ring and the pressing element. This gives the length differential which has been programmed on the gear wheel forming the selector. When the distribution ring abuts on the drum, the drum is driven and the material is continuously allowed to exit. As soon as the drum, by its walls (10d - 20c), is in contact with the strip of material and no longer with the distribution ring, it is released and returns to zero point by the return effect given by the inner spring (18), thus unwinding the strip of material of a complementary length.
Ainsi, par l'invention, on peut programmer facilement les longueurs de format de matériau à découper.Thus, by the invention, it is easy to program the format lengths of material to be cut.
L'agencement du tambour est simple à réaliser.The arrangement of the drum is simple to carry out.
A titre complémentaire et en égard du mode de distribution du matériau , il est prévu l'adjonction d'un dispositif anti-retour (40) du matériau comprenant une barrette (40a) articulée sur un flasque du carter disposé transversalement à l'appareil et derrière le tambour. Cette barrette comprend un patin (40b) appuyant sur un joint disposé sur le rouleau presseur (figure 8). De ce fait, le matériau est bloqué en position. In addition and with regard to the method of distributing the material, provision is made for the addition of a non-return device (40) for the material comprising a bar (40a) articulated on a flange of the casing disposed transversely to the device and behind the drum. This bar includes a pad (40b) pressing on a seal disposed on the pressure roller (Figure 8). As a result, the material is locked in position.
