Abstract

The subject of the invention is related to the technical sector of apparatuses for dispensing wiping(-up) materials. The device according to the invention is noteworthy in that one of the arms of the support (12) has an upper extension (12c) on which is centred a pendular member (16) capable of following as closely as possible the periphery of the roll as the roll diminishes, thus preventing the winding up of a torn strip of material awkwardly about the said roll (R).

Description

Dispositif de guidage de bandes de matériaux enroulées sur un support de stockage,
L'objet de l'invention on rattache au secteur technique des appareils distributeurs de matériaux d'essuyage.
Device for guiding strips of material wound on a storage medium,
The subject of the invention relates to the technical sector of devices for distributing wiping materials.

Plus particulièrement, 1 ' invention se rapporte aux appareils assurant automatiquement la distribution et la coupe de bandes de matériaux présentes en bobine qui sont placés directement en appui et en pression au-dessus d'un tambour a surface anti-glissante incluant le système de coupe ; la longueur des bandes déroulées étant égale a la circonférence du tambour, la distribution et la coupe simultanées étant obtenues par simple traction manuelle sur la bande débordante de l'appareil se repaçant automatiquement après chaque traction en position de débordement,
Ce type d'appareils qui a fait l'objet de nombreux brevets dont le déposant est également le titulaire, fonctionne de manière satisfaisante.
Cependant, avec certaines qualités de matériaux d'essuyage, et lorsque la traction manuelle sur la bande débordante n'est pas exercée approximativement de haut en bas, il peut se produire un déchirement au niveau de la génératrice de contact entzre le tambour et le rouleau de matériau. Dans ce cas, il est nécessaire d'agir sur un bouton de manoeuvre associé au tambour afin d'assurer la sortie de la bande en vue d'une nouvelle traction manuelle. Cette action de chargement est en générale suffisante te néanmoins il peut arriver surtout en fin de rouleau que la bande de matériau stenroule sur le rouleau au lieu de passer derrière le tambour, provoquant ainsi un bourrage et mettant l'appareil en panne du fait que l'utilisateur ne peut avoir accès a l'intérieur.
More particularly, the invention relates to devices automatically distributing and cutting strips of material present on a reel which are placed directly in support and pressure above a drum with an anti-slip surface including the cutting system ; the length of the unrolled strips being equal to the circumference of the drum, the simultaneous distribution and cutting being obtained by simple manual pulling on the overflowing strip of the apparatus which is automatically repositioned after each pull in the overflowing position,
This type of device, which has been the subject of numerous patents of which the applicant is also the owner, works satisfactorily.
However, with certain qualities of wiping material, and when the manual traction on the overflowing strip is not exerted approximately from top to bottom, there may be a tear in the generator of contact between the drum and the roller. of material. In this case, it is necessary to act on an operating button associated with the drum in order to ensure the exit of the strip for a new manual traction. This loading action is generally sufficient, however, it can happen especially at the end of the roll that the strip of material stenroule on the roll instead of passing behind the drum, thus causing a jamming and putting the device down because the user cannot access inside.

Pour éviter cela, on propose le dispositif selon l'invention qui résout le problème de manière simple et efficace, c 'est-a-dire assurer systématiquement la sortie de la bande de matériau en cas de déchirement par action manuelle sur le bouton de chargement,
Pour cela et selon une première caractéristique l'un des bras du support du rouleau de matériau en appui élastique sur le tambour d'entrainement agencé avec des moyens de coupe, présente un prolongement supérieur gur lequel est axé un organe pendulaire apte suivre au plus près 1a périphérie du rouleau au fur et a mesure de sa diminution, en empêchant ainsi l'enroulement d'une bande de matériau déchirée malencontreusement autour dudit rouleau.
To avoid this, the device according to the invention is proposed which solves the problem in a simple and effective manner, that is to say systematically ensuring the exit of the strip of material in the event of tearing by manual action on the loading button. ,
For this and according to a first characteristic, one of the arms of the support of the roll of material in elastic support on the drive drum arranged with cutting means, has an upper extension gur which is oriented a pendulum member able to follow more closely 1a periphery of the roll as it decreases, thereby preventing the winding of a strip of material torn inadvertently around said roll.

Selon une autre caractéristique destinée a faciliter l'engagement d'un rouleau neuf, l'organe pendulaire est associé a un taquet mbile retenant ledit organe pendulaire en position arrière lorsque le support du rouleau est relevé en vue du chargement en rouleau neuf. According to another characteristic intended to facilitate the engagement of a new roller, the pendulum member is associated with a movable cleat retaining said pendulum member in the rear position when the support of the roller is raised for loading into a new roller.

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

In order to make the object of the invention more concrete, it is now described in a nonlimiting embodiment illustrated in the figures of the drawings and applied to a device for simultaneous distribution and cutting as defined in the preamble.

Pour la bonne compréhension de l'invention, on rappelle succintement les principaux éléments de ce type d'appareils largement décrit dans les précédents brevets du déposant. For a good understanding of the invention, we briefly recall the main elements of this type of device widely described in the previous patents of the applicant.

à partir d'une plaque-support (1) de fixation murale prolongée latéralement par des parois (1a-1b). from a support plate (1) for wall fixing extended laterally by walls (1a-1b).

est fixé a rotation un tambour (2) a surface extérieure (2a) anti-glissante. D'un côté, l'axe du tambour est relié a un levier-excentrique C3) a ressort de lancement (4) et de l'autre côté a un bouton de manoeuvre (5). Du côté du levier (3), le palier (1b1) de la paroi (1b) porte une came fixe (6) sur laquelle s'appuie un galet (7) relié à une lame de coupe dentelée (8) logée et articulée dans le tambour. a non-slip drum (2a) with an external surface (2a) is rotatably attached. On one side, the axis of the drum is connected to an eccentric lever C3) with a launching spring (4) and on the other side to an operating button (5). On the side of the lever (3), the bearing (1b1) of the wall (1b) carries a fixed cam (6) on which rests a roller (7) connected to a serrated cutting blade (8) housed and articulated in the drum.

De l'autre côté, le tambour est agencé pour coopérer avec des organes du type amortisseur (9), cliquet (10) agissant en fin de course du tambour pour l'arrêter dans une position où la bande (B1) de matériau suivant la coupe déborde sous l'appareil en passant entre deux rouleaux de guidage (11),
Le rouleau (R), de matériau d'essuyage est monté a rotation libre sur les bras (12.1) (12.2) d'un support (12) articulé en (13) sur la plaque-support (1) et est rappelé constamment en appui sur le tambour par un moyen élastique (14),
L'ensemble de ces organes est enfermé dans un capot (non représenté) verrouillé sur la plaque (1)
Le fonctionnement de ce genre d'appareil est le suivant : lorsqu'on tire manuellement sur la bande (B1), le tambour (2) est entraîné en rotation et la lame de coupe (8), par son galet ( appliqué sur la came (6) décrit une trajectoire courbe l'amenant a l'extérieur du tambour en passant par une ouverture (2b) du tambour.Le matériau étant tendu de part et d'autre de la lame, celle-ci pénètre dans ledit matériau en continuant sa trajectoire jusqu'au détachement. A ce moment, le tambour lancé par le levierexcentrique (3) continue sa course en soulevant le cliquet (10), puis l'amortisseur (9) coopérant avec une saillie du tambour l'arrente tandis que le cliquet (10) retomé empêche ledit tambour de revenir en arrière, l'appareil est alors prêt pour une nouvelle distribution.
On the other side, the drum is arranged to cooperate with members of the shock absorber type (9), pawl (10) acting at the end of the drum's travel to stop it in a position where the strip (B1) of material according to the section extends beyond the device passing between two guide rollers (11),
The roller (R) of wiping material is mounted to rotate freely on the arms (12.1) (12.2) of a support (12) articulated in (13) on the support plate (1) and is constantly recalled in support on the drum by elastic means (14),
All of these members are enclosed in a cover (not shown) locked on the plate (1)
The operation of this type of device is as follows: when manually pulling on the strip (B1), the drum (2) is rotated and the cutting blade (8), by its roller (applied to the cam (6) describes a curved path leading it to the outside of the drum by passing through an opening (2b) of the drum. The material being stretched on either side of the blade, the latter penetrates into said material while continuing its trajectory until detachment. At this moment, the drum launched by the eccentric lever (3) continues its race by lifting the pawl (10), then the shock absorber (9) cooperating with a projection of the drum arrives while the retomated pawl (10) prevents said drum from turning back, the device is then ready for a new distribution.

Si l'on tire sur la bande (B1) d'une manière désordonnée, il peut arriver avec certains matériaux d'essuyage fragiles, et plus particulièrement lorsqu'on est en fin de rouleau, qu'un déchirement se produise au niveau de la génératrice de contact entre le rouleau et le tambour. If one pulls on the strip (B1) in a disorderly manner, it can happen with certain fragile wiping materials, and more particularly when one is at the end of the roll, that a tear occurs at the level of the generating contact between the roller and the drum.

Dans ce cas, la bande (B1) ne sort pas sous l'appareil et il faut alors actionner le bouton (S) entrainant le tambour pour amener la bande en débordement. Cette action n'est pas toujours efficace car la bande de matériau peut accidentellement s'enrouler autour du rouleau au lieu de descendre derrière le tambour, ce qui amène un bourrage puis un blocage complet de l'appareil. In this case, the strip (B1) does not come out under the appliance and it is then necessary to press the button (S) driving the drum to bring the strip overflowing. This action is not always effective because the strip of material can accidentally wrap around the roller instead of descending behind the drum, which causes a jam and then a complete blockage of the device.

Pour éviter cette panne, et assurer systématiquement la sortie d'une bande déchirée sous l'action du bouton (5), on a conçu le dispositif de guidage selon l'invention,
Pour cela, l'un des bras du support de rouleau (12) présente un prolongement supérieur (12c) sur lequel est réalisé dans la partie supérieure un orifice (12c1) destiné a recevoir un axe C15) d'articulation pour un organe pendulaire C16) qui comprend A cet effet une patte de suspension (16a) avec un orifice (16a1), L'organe (16) forme une palette (16b) s'étendant perpendiculairement a la patte (16a) et de manière inclinée par rapport a ladite patte.Par simple gravité, l'organe (16) ainsi suspendu, peut suivre au plus près par ia partie avant de la palette, la périphérie du rouleau de matériau Cfigure 4) au fur et à mesure de sa diminution. De la sorte, si un déchirement accidentel se produit lors d'une action anormale de traction, la bande déchirée arrêtée par la palette ne peut s'enrouler sur le rouleau (R) et en actionnant le bouton (6), on obtient toujours la sortie de la bande (B1).
To avoid this breakdown, and systematically ensure the exit of a torn strip under the action of the button (5), the guide device according to the invention has been designed,
For this, one of the arms of the roller support (12) has an upper extension (12c) on which is formed in the upper part an orifice (12c1) intended to receive an axis C15) of articulation for a pendulum member C16 ) which comprises for this purpose a suspension lug (16a) with an orifice (16a1), the member (16) forms a pallet (16b) extending perpendicularly to the lug (16a) and in an inclined manner with respect to said patte.Par simple gravity, the organ (16) thus suspended, can follow as closely as possible by the front part of the pallet, the periphery of the roll of material Cfigure 4) as it decreases. In this way, if an accidental tear occurs during an abnormal pulling action, the torn strip stopped by the pallet cannot be wound on the roller (R) and by actuating the button (6), one always obtains the exit from the strip (B1).

Le débattement angulaire de l'organe C16) peut être limité par tous moyens tels que la vis 17) ou saillie similaire, solidaire de la patte (16a) et traversant une lumière (12c2) exécutée avec un rayon ayant pour centre l'orifice d'articulation (12c1),
Pour faciliter l'engagement d'un rouleau neuf entre les bras (12.1 - 12.2) du support, on a également prévu un dispositif de retenue en arrière de l'organe pendulaire (16).
The angular movement of the member C16) can be limited by any means such as the screw 17) or similar projection, integral with the tab (16a) and passing through a lumen (12c2) executed with a radius having the orifice d as its center. 'articulation (12c1),
To facilitate the engagement of a new roller between the arms (12.1 - 12.2) of the support, a retaining device has also been provided behind the pendulum member (16).

A cet effet, un taquet (18) est monté de manière mobile sur le prolongement (12c) par deux vis (19-20) ou organes similaires traversant des ouvertures allongées (12c3 - 12c4) du prolongement, L'extrémité avant (OSa) effilée du taquet est destinée à s'engager sous un cran (16a2) de la patte (16a1) lorsque les bras (12a - 12b) sont relevés en vue du chargement (figure 4), cela par déplacement du taquet dont l'extrémité arrière (18b) débordant du prolongement (12c) s'appuie contre la plaque (1). For this purpose, a cleat (18) is movably mounted on the extension (12c) by two screws (19-20) or similar members passing through elongated openings (12c3 - 12c4) of the extension, the front end (OSa) tapered cleat is intended to engage under a notch (16a2) of the tab (16a1) when the arms (12a - 12b) are raised for loading (Figure 4), this by displacement of the cleat whose rear end (18b) projecting from the extension (12c) bears against the plate (1).

Les avantages ressortent bien de la description, on souligne encore le guidage sûr du matériau entre son rouleau de stockage et la sortie de l'appareil de distribution dans toutes les circonstances, en particulier en cas de rupture inopinée a l'intérieur de l'appareil.  The advantages emerge clearly from the description, it is further emphasized the safe guiding of the material between its storage roller and the outlet of the dispensing device in all circumstances, in particular in the event of an unexpected break inside the device. .
