Description

APPAREIL DISTRIBUTEUR DE MATERIAU D'ESSUYAGE APPARATUS FOR DISPENSING WIPING MATERIAL
L'invention se rattache au secteur technique des appareils de distribution de papier d'essuyage en ouate de cellulose, papier crêpé ou matériau similaire, destiné plus particulièrement à l'essuyage des mains des utilisateurs, à la distribution de papier toilette, à la distribution de serviettes en papier. Ces papiers peuvent être sous forme pliée ou nonpliée.The invention relates to the technical sector of devices for dispensing wiping paper in cellulose wadding, crepe paper or similar material, intended more particularly for wiping the hands of users, for dispensing toilet paper, for dispensing of paper towels. These papers can be folded or unfolded.
Le Demandeur a développé de nombreux brevets sur des appareils du type précité dans des versions automatique et semi-automatique, et distribution de bandes de papier en provenance d'une bobine de chargement.The Applicant has developed numerous patents on devices of the aforementioned type in automatic and semi-automatic versions, and distribution of paper strips from a loading reel.
On rappelle succinctement les principaux composants d'un tel appareil. Un appareil distributeur de matériau d'essuyage référencé dans son ensemble par (1) comprend un carter (2), un couvercle (3), un tambour (4), un dispositif de coupe (5 - 6) intégré dans le tambour, 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 est agencé avec des flasques (2a) susceptibles de recevoir le porte-bobine (9) d'une bobine d'essuyage (B). Ces flasques peuvent être à position fixe et, dans ce cas, la bobine de matériau d'essuyage est montée en suspension par rapport au tambour. Dans une variante, les flasques ou bras d'un porte-bobine sont montés articulés par rapport au carter de telle sorte que la bobine de matériau d'essuyage vienne en contact avec le tambour proprement dit.The main components of such an apparatus are briefly recalled. A device for dispensing wiping material referenced as a whole by (1) comprises a casing (2), a cover (3), a drum (4), a cutting device (5 - 6) integrated in the drum, as well that means for launching and returning the drum including an eccentric (7) and a spring (8). In its upper part, the casing is arranged with flanges (2a) capable of receiving the reel holder (9) of a wiping reel (B). These flanges can be in a fixed position and, in this case, the reel of wiping material is mounted in suspension relative to the drum. In a variant, the flanges or arms of a reel holder are mounted articulated with respect to the casing so that the reel of wiping material comes into contact with the drum proper.
De telles dispositions sont bien courantes sur ce type d'appareil. La traction de la bande de papier par l'utilisateur est susceptible d'être exercée de manière très variable avec une force plus ou moins importante, sans compter le sens directionnel de la traction qui peut être un paramètre supplémentaire dans le fonctionnement de l'appareil distributeur. Il peut alors se produire un phénomène d'apparition de boucles entre la bobine de matériau d'essuyage et le tambour sur une longueur de bande pouvant être de quelques centimètres. Pour remédier à cet inconvénient, le Demandeur a développé des dispositifs antiboucle notamment dans le brevet FR N° 2643808. Ces dispositifs anti-boucle font intervenir des ensembles de leviers basculants montés par rapport au porte-bobine et qui sont susceptibles d'avoir un effet de pivotement pour réduire ou compenser le phénomène de la boucle et mettre en tension la bande de matériau. De tels ensembles sont de fonctionnement très satisfaisant mais sont susceptibles de gêner le chargement de l'appareil, étant face et dans le plan frontal de la bobine de matériau.Such provisions are very common on this type of device. The traction of the strip of paper by the user is likely to be exerted in a very variable way with a more or less significant force, without counting the directional direction of the traction which can be an additional parameter in the operation of the device. distributor. A phenomenon of appearance of loops can then occur between the reel of wiping material and the drum over a length of strip which may be a few centimeters. To remedy this drawback, the Applicant has developed anti-loop devices in particular in patent FR No. 2643808. These anti-loop devices involve sets of tilting levers mounted relative to the reel holder and which are capable of having an effect swivel to reduce or compensate for the loop phenomenon and tension the strip of material. Such assemblies are very satisfactory in operation but are liable to interfere with the loading of the device, being opposite and in the frontal plane of the reel of material.
Un autre inconvénient réside aussi dans le coût des moules nécessaires à la réalisation du dispositif anti-boucle. Malgré toutes les précautions prises, il peut se produire aussi la distribution de plusieurs bandes de matériau.Another drawback also lies in the cost of the molds necessary for the production of the anti-loop device. Despite all the precautions taken, it can also occur the distribution of several strips of material.
Le but recherché selon l'invention était donc de remédier à ces inconvénients en proposant une solution mieux adaptée qui ne soit pas une gêne pour l'utilisateur lors du montage et du chargement de l'appareil.The aim sought after according to the invention was therefore to remedy these drawbacks by proposing a more suitable solution which would not be a nuisance for the user during assembly and loading of the device.
Selon un autre but recherché de l'invention, le Demandeur s'est orienté sur un concept technique qui puisse être, dans son principe, utilisé aussi bien pour des appareils où la bobine de chargement est suspendue sur les fiasques porteurs, ou la bobine est en appui sur le tambour grâce au pivotement d'un porte-bobine avec bras ou flasques articulés.According to another desired object of the invention, the Applicant is guided by a technical concept which can in principle be used both for devices where the loading coil is suspended on the carrier flasks, or the coil is resting on the drum thanks to the pivoting of a reel holder with articulated arms or flanges.
Selon une première caractéristique, l'appareil distributeur de matériau d'essuyage, du type comprenant un carter, un couvercle, un tambour, un dispositif de coupe intégré dans le tambour, des moyens de lancement et de rappel du tambour incluant un excentrique et un ressort de lancement, disposés à partir d'un côté latéral du tambour, les flasques latéraux étant agencés pour supporter le porte- bobine, est remarquable en ce qu'il comprend un dispositif anti-boucle de matériau en provenance de la bobine de matériau incluant au moins un mécanisme agissant sur le porte-bobine en bloquant en position ce dernier, ce mécanisme étant disposé sur l'un des flasques du carter, et étant actionné par un dispositif en masselotte intégré dans le mouvement du tambour en rotation et assurant la mise en fonctionnement ou non du blocage du porte-bobine en cas de sollicitation et traction forte de la bande de matériau.According to a first characteristic, the device for dispensing wiping material, of the type comprising a casing, a cover, a drum, a cutting device integrated in the drum, means for launching and returning the drum including an eccentric and a launching spring, arranged from a lateral side of the drum, the lateral flanges being arranged to support the reel holder, is remarkable in that it comprises an anti-loop device for material coming from the reel of material including at least one mechanism acting on the reel holder by locking the latter in position, this mechanism being arranged on one of the flanges of the casing, and being actuated by a counterweight device integrated in the movement of the rotating drum and ensuring the operation or not of the blocking of the reel holder in the event of stress and strong traction of the strip of material.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins. L'appareil distributeur référencé dans son ensemble par (1) est agencé avec un dispositif anti-boucle de matériau en provenance de la bobine de matériau, ce dispositif incluant au moins un premier mécanisme agissant sur le porte-bobine en bloquant en position celui-ci, ledit premier mécanisme étant agencé pour être disposé sur un premier flasque de l'appareil distributeur, et ce aussi bien pour des appareils présentant la bobine de matériau en suspension sur un flasque fixe, que la bobine en appui sur le tambour, les bras d'un porte-bobine supports articulé.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.

En pratique, il convient d'identifier certains composants complémentaires à l'appareil distributeur dans chacune de ses versions à flasque fixe ou porte-bobine articulé à partir desquels les mécanismes du dispositif de l'invention sont mis en œuvre.In practice, it is appropriate to identify certain components complementary to the dispensing device in each of its versions with fixed flange or articulated reel holder from which the mechanisms of the device of the invention are implemented.
Le tambour (4) est du type comprenant un moyen dont les extrémités latérales forment flasque support du porte-lame de coupe. L'un des flasques est en pratique agencé avec une plaque ovoïde (10) munie d'une ouverture profilée (10a) tandis qu'une seconde plaque intérieure (10b) également formée solidaire avec le manchon (11) support du flasque (10), présente une ouverture (10c) pour l'introduction d'un axe support (12a) d'une masselotte (12) articulée. Ladite masselotte présente ainsi un doigt (12b) formant axe d'articulation, et un déportThe drum (4) is of the type comprising a means the lateral ends of which form a flange supporting the cutting blade holder. One of the flanges is in practice arranged with an ovoid plate (10) provided with a profiled opening (10a) while a second inner plate (10b) also formed integral with the sleeve (11) supporting the flange (10) , has an opening (10c) for the introduction of a support pin (12a) of an articulated flyweight (12). Said flyweight thus has a finger (12b) forming a hinge pin, and an offset
(12c) en saillie extérieure susceptible de traverser l'ouverture (10a) formée sur la plaque ovoïde (10). L'extrémité en saillie (12c) de la masselotte (12) vient ainsi sensiblement en regard de la face intérieure du flasque du carter. Cette masselotte est montée libre en pivotement et elle est articulée par gravité lors de la rotation du tambour (4) et donc de ses flasques d'extrémité. Selon l'invention, le dispositif anti-boucle susceptible d'agir sur le porte-bobine monté sur le flasque fixe est conçu par l'agencement suivant :(12c) projecting from the outside and capable of passing through the opening (10a) formed on the ovoid plate (10). The projecting end (12c) of the counterweight (12) thus comes substantially opposite the internal face of the flange of the casing. This counterweight is mounted to pivot freely and it is articulated by gravity during the rotation of the drum (4) and therefore of its end flanges. According to the invention, the anti-loop device capable of acting on the spool holder mounted on the fixed flange is designed by the following arrangement:
Le flasque porte-bobine (2a) est agencé pour recevoir un embout (13) monté tournant et susceptible de s'engager dans le mandrin (14) de la bobine de matériau. Cet embout (13) présente une portée cylindrique (13a) s'engageant dans ledit mandrin et se prolonge par un disque (15) agencé sur sa périphérie avec une multitude de saillies ou dents (15a) espacées régulièrement entre elles. Entre le flasque latéral (2a) fixe du carter et le disque (15) de l'embout, est monté un levier (16) de grande longueur dont la partie supérieure (16a) formant tête est montée pivotante sur un axe de liaison (17) solidaire du flasque (2a) du carter, et dont la position permet le rapprochement pour assurer la fonction de blocage. L'extrémité supérieure (16a) dudit levier assure la fixation d'une extrémité (18a) d'un ressort de rappel (18) dont l'autre extrémité (18b) est solidaire du flasque du carter. Ledit ressort de rappel (18) est hors tension en cas de non sollicitation du levier (16) Ce dernier est par ailleurs agencé avec un doigt (16b) en saillie situé en regard sur le disque cranté. La partie basse (16c) du levier (16) est agencée avec une extrémité située en regard du flasque latéral du tambour supportant la masselotte (12) précitée. En outre, ledit levier (16) présente, près de sa partie basse, une forme intérieure en crochet (16d) qui est susceptible d'être guidée et maintenue par une patte fixe (19) solidaire de la face intérieure (2a) du flasque du carter, limitant le débattement latéral du levier. En outre et en opposition à cette patte, une butée (20) en saillie est susceptible de retenir le levier (16) dans l'autre sens en agissant ainsi comme limiteur de course.The spool holder flange (2a) is arranged to receive an end piece (13) mounted to rotate and capable of engaging in the mandrel (14) of the material reel. This tip (13) has a cylindrical surface (13a) engaging in said mandrel and is extended by a disc (15) arranged on its periphery with a multitude of projections or teeth (15a) regularly spaced therebetween. Between the fixed lateral flange (2a) of the casing and the disc (15) of the end piece, is mounted a lever (16) of great length, the upper part (16a) of which forms a head is pivotally mounted on a connecting pin (17 ) integral with the flange (2a) of the casing, and whose position allows the approximation to ensure the locking function. The upper end (16a) of said lever secures one end (18a) of a return spring (18), the other end (18b) of which is secured to the flange of the casing. Said return spring (18) is de-energized in the event that the lever (16) is not stressed. The latter is also arranged with a projecting finger (16b) located opposite the notched disc. The lower part (16c) of the lever (16) is arranged with one end situated opposite the lateral flange of the drum supporting the aforementioned counterweight (12). In addition, said lever (16) has, near its lower part, an internal hook shape (16d) which can be guided and maintained by a fixed tab (19) secured to the internal face (2a) of the flange. of the housing, limiting the lateral movement of the lever. In addition and in opposition to this tab, a projecting stop (20) is capable of retaining the lever (16) in the other direction, thus acting as a stroke limiter.
A titre complémentaire, l'embout (13) récepteur du mandrin de la bobine d'essuyage peut être agencé avec un evidement (13b) central périphérique formant logement susceptible de recevoir des moyens à roulement (21) du type à aiguilles maintenue par des demi-brides (22) semi-circulaires Une bande ou courroie (23) recouvre l'ensemble et sert de plan d'appui à la bobine. Dans cette mise en œuvre, le fonctionnement du dispositif est le suivant. Lorsque l'opérateur tire la bande de matériau selon une force trop importante, il peut arriver que la masselotte (12) n'ait pas le temps matériel de basculer dans son logement en vue de passer sous extrémité du levier (16). Dans cette situation, ladite masselotte (12) emportée par la vitesse de rotation du tambour vient alors en butée contre l'extrémité basse du levier (16) précité. Elle provoque de par son appui, le basculement dudit levier et ce à rencontre de son ressort (18) associé à la partie supérieure formant tête. En outre, le doigt (16b) en saillie est également basculé et vient pénétrer dans l'espace en regard entre deux dents (15a) consécutives du disque cranté. Cette pénétration provoque alors le blocage en position du porte- bobine. En outre, la courroie (23) montée sur l'embout (13) assure un effet de freinage complémentaire du mandrin de bobine.As a complement, the end piece (13) receiving the mandrel of the wiping reel can be arranged with a central peripheral recess (13b) forming a housing capable of receiving rolling means (21) of the needle type maintained by half - semi-circular flanges (22) A band or belt (23) covers the assembly and serves as a support plane for the coil. In this implementation, the operation of the device is as follows. When the operator pulls the strip of material with too great a force, it may happen that the counterweight (12) does not have the material time to tilt in its housing in order to pass under the end of the lever (16). In this situation, said counterweight (12) carried by the speed of rotation of the drum then comes into abutment against the lower end of the aforementioned lever (16). It causes, by its support, the tilting of said lever and this against its spring (18) associated with the upper part forming a head. In addition, the projecting finger (16b) is also tilted and enters the space opposite between two consecutive teeth (15a) of the notched disc. This penetration then causes the spool holder to lock in position. In addition, the belt (23) mounted on the end piece (13) provides an additional braking effect on the spool core.
En variante, le disque (15) peut être réalisé sous forme d'une section polygonale contre laquelle prend appui successivement le doigt (16b) précité. D'autres configurations du disque (15) peuvent être engagées pour assurer l'effet d'appui, de butée et de blocage du levier.As a variant, the disc (15) can be produced in the form of a polygonal section against which the aforementioned finger (16b) bears successively. Other configurations of the disc (15) can be engaged to ensure the support, stop and blocking effect of the lever.
La remise à niveau est automatique par le retour du tambour grâce au ressort de rappel de l'excentrique et l'effet de retour en arrière du matériau sur le porte- bobine.The leveling is automatic by the return of the drum thanks to the return spring of the eccentric and the backward effect of the material on the spool holder.
On se réfère maintenant à la seconde mise en œuvre illustrée figures 5 à 8. D'une manière connue, le support porte-bobine (25) est établi selon une forme en U dont les bras latéraux (25a) sont agencés avec un embout (13) susceptible de pénétrer dans le mandrin de la bobine. L'un des bras (25a) de ce support porte-bobine peut être lui-même monté pivotant pour faciliter le chargement de l'appareil. Des moyens élastiques de rappel et de mise en tension de ce support porte-bobine permet de mettre en contact et appui la bobine et le tambour.We now refer to the second implementation illustrated in FIGS. 5 to 8. In a known manner, the reel holder support (25) is established in a U shape, the lateral arms (25a) of which are arranged with a nozzle ( 13) likely to penetrate into the spool core. One of the arms (25a) of this reel holder can be itself pivotally mounted to facilitate loading of the device. Elastic means of return and tensioning of this reel holder support makes it possible to bring the coil and the drum into contact and support.
Le dispositif anti-boucle est ainsi agencé comme suit. L'embout (13) pénétrant dans le mandrin est réalisé de la manière décrite précédemment, de sorte que les références utilisées sont les mêmes.The anti-loop device is thus arranged as follows. The end piece (13) penetrating into the mandrel is produced in the manner described above, so that the references used are the same.
Le tambour est agencé de manière similaire avec, près de l'un de ses flasques, une masselotte (12) assurant la fonction anti-retour du tambour.The drum is similarly arranged with, near one of its flanges, a counterweight (12) ensuring the non-return function of the drum.
Dans cette mise en œuvre, le mécanisme anti-boucle est le suivant.In this implementation, the anti-loop mechanism is as follows.
Un premier levier (26) est disposé à partir de la paroi de fond du carter en étant articulé sur un axe (27) pénétrant dans le flasque du carter en regard et sur une patte (28) intérieure recevant à articulation le support porte-bobine à l'aide d'une portée (29) et d'un axe de liaison (30) Le bras porte-bobine est avantageusement profilé en U de sorte qu'il peut recevoir intérieurement un bloc (31) parallélépipédique susceptible de coulisser à l'intérieur dudit bras. La face de fond dudit bras présente une fente (32) orientée oblique et oblongue susceptible d'autoriser le déplacement et le coulissement d'un doigt (33) en saillie établi sur le bloc (31) précité, selon des positions haute et basse. Ce bloc (31) est solidaire d'un second levier (34) profilé en L dont la branche supérieure (34a) est accouplée au bloc (31) et la branche inférieure (34b) est montée sur l'axe de pivotement du support porte-bobine. L'extrémité (34b) dudit second levier présente une échancrure oblongue (34c) dans laquelle coulisse ledit axe (30) permettant ainsi de faire varier la position du second levier (34) et donc du bloc (31) qui lui est associé. La patte (28) moulée dans le carter est établie entre la partie basse dudit second levier (34) et la zone (26a) de pivotement et d'ancrage dudit premier levierA first lever (26) is arranged from the bottom wall of the casing, being articulated on an axis (27) penetrating into the flange of the casing opposite, and on an inner tab (28) receiving the spool holder support at articulation. using a bearing surface (29) and a connecting pin (30) The spool-holder arm is advantageously U-shaped so that it can internally receive a parallelepipedal block (31) capable of sliding at the inside said arm. The bottom face of said arm has an oblique and oblong oriented slot (32) capable of allowing the displacement and sliding of a projecting finger (33) established on the aforementioned block (31), in high and low positions. This block (31) is integral with a second lever (34) L-shaped whose upper branch (34a) is coupled to the block (31) and the lower branch (34b) is mounted on the pivot axis of the door support. -coil. The end (34b) of said second lever has an oblong notch (34c) in which slides said axis (30) thus making it possible to vary the position of the second lever (34) and therefore of the block (31) which is associated with it. The tab (28) molded in the casing is established between the lower part of said second lever (34) and the zone (26a) of pivoting and anchoring of said first lever
(26). La patte (28) présente ainsi une ouverture (28a) de passage de l'axe de liaison avec le premier levier (26) et une seconde ouverture (28b) de passage de l'axe de liaison avec le second levier (34) et la base d'articulation du bras porte-bobine. Un ressort de rappel (36) est disposé entre le premier levier (26) avec un point de fixation et le second levier (34) à l'endroit de sa partie coudée (34d). Le positionnement est donc le suivant.(26). The tab (28) thus has an opening (28a) for the passage of the connecting axis with the first lever (26) and a second opening (28b) for the passage of the connecting axis with the second lever (34) and the articulation base of the spool arm. A return spring (36) is disposed between the first lever (26) with an attachment point and the second lever (34) at the location of its bent part (34d). The positioning is therefore as follows.
En phase de non sollicitation, c'est-à-dire que le tambour de l'appareil tourne normalement et la masselotte reprend sa position normale, il n'y a aucune intervention sur le premier levier. Le porte-bobine peut tourner normalement.In the non-solicitation phase, that is to say that the device drum turns normally and the flyweight returns to its normal position, there is no intervention on the first lever. The spool pin can rotate normally.
Dans le cas d'une sollicitation brusque par une traction trop forte par l'utilisateur, la masselotte (12) associée au tambour peut ne pas reprendre sa place initiale. Elle vient alors en butée contre l'extrémité libre (26c) du premier levier (26) en provoquant son pivotement et son basculement. Ce pivotement va mettre en contact l'extrémité libre du premier levier avec la face inférieure du second levier (34) en lui engendrant un mouvement de déplacement vers le haut le long du bras porte-bobine. Ce mouvement va entraîner le déplacement du doigt (33) associé audit bloc (31) et permettre son positionnement à l'intérieur entre deux dents (15a) consécutives de la plaque circulaire (15) crantée de l'embout. Il y aura également un blocage en position de l'embout empêchant la rotation de la bobine. La libération du levier (26) par la masselotte s'effectue automatiquement dans les mêmes conditions qu'indiqué précédemment.In the event of sudden stress by too strong traction by the user, the flyweight (12) associated with the drum may not return to its original place. It then abuts against the free end (26c) of the first lever (26) causing it to pivot and tilt. This pivoting will bring the free end of the first lever into contact with the underside of the second lever (34), causing it to move upward along the spool arm. This movement will cause the finger (33) associated with said block (31) to move and allow it to be positioned inside between two consecutive teeth (15a) of the notched circular plate (15) of the nozzle. There will also be a blocking in position of the end cap preventing rotation of the coil. The lever (26) is released by the counterweight automatically under the same conditions as indicated above.
II y a lieu maintenant de se référer à la figure 2 des dessins dans lesquels le second flasque porte-bobine est agencé à son tour avec un moyen complémentaire permettant le retour de la bobine.Reference should now be made to FIG. 2 of the drawings in which the second reel-holder flange is in turn arranged with additional means allowing the return of the reel.
Dans cette mise en œuvre complémentaire qui a pour but de permettre le retour en arrière de la bobine pour réenrouler la bobine en cas d'apparition d'une boucle, le mécanisme comprend les agencements suivants.In this additional implementation which aims to allow the rewinding of the reel to rewind the reel in the event of the appearance of a loop, the mechanism includes the following arrangements.
Le flasque, dans la version fixe, est agencé avec un moyeu central (37), fixé par vis ou autrement. Ce moyeu (37) est épaulé et reçoit en extrémité un embout (38) profilé en forme de chapeau avec une portée extérieure (38a) réceptrice du mandrin de la bobine et une forme en couvercle (38b) entourant le moyeu précité. Un ressort à spirale (39) est disposé dans le logement ainsi réalisé avec une extrémité (39a) fixée sur le flasque et l'autre extrémité (39b) fixée sur le couvercle. La rotation de la bobine sous l'effet de traction du papier par l'utilisateur va amener le moyen porte-bobine à tourner dans un sens en provoquant le bandage du ressort et en emmagasinant de l'énergie. Cette tension est maintenue pendant le temps de maintien de l'extrémité libre de la bande de papier. La suppression de ce maintien provoque par détente élastique, le retour en arrière de la bande de matériau en supprimant son effet boucle qui aurait pu être réalisé. Une butée (40) assure la limitation de course et de rotation de l'embout (38).The flange, in the fixed version, is arranged with a central hub (37), fixed by screw or otherwise. This hub (37) is shouldered and receives at the end a shaped cap (38) in the form of a cap with an outer bearing surface (38a) receiving the spool mandrel and a cover shape (38b) surrounding the aforementioned hub. A spiral spring (39) is disposed in the housing thus produced with one end (39a) fixed to the flange and the other end (39b) fixed to the cover. The rotation of the reel under the pulling effect of the paper by the user will cause the reel holder means to turn in one direction, causing the spring to tire and storing energy. This tension is maintained during the holding time of the free end of the paper strip. The elimination of this retention causes, by elastic relaxation, the backward movement of the strip of material while eliminating its loop effect which could have been achieved. A stop (40) limits the stroke and rotation of the end piece (38).
Un appareil distributeur de bande de matériau d'essuyage peut donc être agencé avec les différents mécanismes pour éviter les effets de boucles précités. A device for dispensing a strip of wiping material can therefore be arranged with the various mechanisms to avoid the above-mentioned effects of loops.
