Description

L'invention se rapporte à un dispositif pour mouiller de façon uniforme une bande souple telle qu'une bande de papier ou tout autre support souple préalablement encollé du commerce, utilisé pour l'affranchissement des lettres, paquets et colis, pour l'emballage et l'étiquetage.The invention relates to a device for uniformly wetting a flexible strip such as a strip of paper or any other flexible support previously glued commercially, used for franking letters, packages and parcels, for packaging and labeling.

Les dispositifs les plus répandus, car les plus simples, pour mouiller une bande souple préalablement encollée comportent un élément de mouillage constitué par une éponge ou un feutre. Il est connu que ce type d'élément de mouillage n'a pas une bonne tenue dans le temps. La demande de brevet européen N° 0293316 décrit un dispositif pour mouiller des étiquettes préalablement encollées qui comprend un élément de mouillage sous forme d'une brosse constituée d'une nappe de fils. La brosse est placée dans une cuve remplie d'un liquide de mouillage apte à diluer la colle. La partie inférieure de la brosse baigne dans le liquide de mouillage maintenu à niveau constant. La partie supérieure de la brosse, mouillée du liquide par capillarité, est maintenue en contact avec la face encollée des étiquettes au cours de leur défilement devant la brosse. Si cette brosse a une meilleure tenue dans le temps qu'une éponge ou un feutre, elle présente l'inconvénient de ne pas répartir régulièrement, dans le temps, le liquide de mouillage sur la face encollée des étiquettes du fait qu'elle se charge intempestivement de colle. En effet, le raclage de la face encollée des étiquettes sur les extrémités des fils de la brosse provoque un dépôt de colle entre les fils de la brosse. Il en résulte un phénomène d'encrassement de la brosse du fait que la colle reste piégée entre les fils de la brosse sans possibilité d'être évacuée au cours du défilement des étiquettes. Ceci entraîne un mauvais transfert de liquide de mouillage aux étiquettes, certaines parties de la face encollée des étiquettes étant lavées, et il en résulte que le mouillage des étiquettes n'est pas uniforme dans le temps.The most widespread devices, because the simplest, for wetting a flexible strip previously glued comprise a wetting element constituted by a sponge or a felt. It is known that this type of wetting element does not hold up well over time. European patent application No. 0293316 describes a device for wetting previously glued labels which comprises a wetting element in the form of a brush consisting of a layer of wires. The brush is placed in a tank filled with a wetting liquid capable of diluting the glue. The lower part of the brush is immersed in the wetting liquid kept at a constant level. The upper part of the brush, wetted with liquid by capillary action, is kept in contact with the glued side of the labels during their movement in front of the brush. If this brush has a better resistance over time than a sponge or a felt, it has the disadvantage of not regularly distributing, over time, the wetting liquid on the glued side of the labels because it becomes charged accidentally glue. Indeed, the scraping of the glued side of the labels on the ends of the brush wires causes a deposit of glue between the brush wires. This results in a fouling phenomenon of the brush due to the fact that the adhesive remains trapped between the wires of the brush without the possibility of being removed during the movement of the labels. This results in poor transfer of wetting liquid to the labels, certain parts of the adhesive side of the labels being washed, and the result is that the wetting of the labels is not uniform over time.

Le but de l'invention est de proposer un dispositif pour mouiller une bande souple comportant un élément de mouillage qui ne présente pas les inconvénients précités.The object of the invention is to provide a device for wetting a flexible strip comprising a wetting element which does not have the aforementioned drawbacks.

A cet effet, l'invention a pour objet un dispositif pour mouiller une bande souple ayant une face au moins partiellement encollée, comportant un élément de mouillage ayant une partie inférieure baignant dans un liquide de mouillage et une partie supérieure mouillée dudit liquide par capillarité, en contact avec face encollée au cours du défilement, selon une direction de défilement, de ladite bande contre ledit élément de mouillage, caractérisé en ce que l'élément de mouillage est un barreau rigide dont la partie supérieure est traversée, selon ladite direction de défilement de la bande souple, par une pluralité de fentes de capillarité ayant des fonds respectifs baignant dans le liquide de mouillage.To this end, the subject of the invention is a device for wetting a flexible strip having an at least partially glued face, comprising a wetting element having a lower part immersed in a wetting liquid and an upper part wetted by said capillary liquid, in contact with glued face during the running, in a running direction, of said strip against said wetting element, characterized in that the wetting element is a rigid bar whose upper part is crossed, in said running direction of the flexible strip, by a plurality of capillary slots having respective bottoms immersed in the wetting liquid.

Un tel élément de mouillage rigide n'est pas sujet à l'usure. Il n'est pas non plus sujet à l'encrassement du fait que l'orientation des fentes de capillarité selon la direction de défilement de la bande souple permet une évacuation continue des résidus de colle au cours du défilement de la bande, par canalisation du liquide de mouillage dans les fentes de capillarité. Le mouillage de la bande souple, sous forme de lignes parallèles de collage, reste uniforme dans le temps.Such a rigid wetting element is not subject to wear. It is also not subject to fouling because the orientation of the capillary slots along the direction of travel of the flexible strip allows continuous removal of adhesive residues during the travel of the strip, by channeling the wetting liquid in the capillary slots. The wetting of the flexible strip, in the form of parallel bonding lines, remains uniform over time.

Selon une autre caractéristique de l'invention, le barreau est pourvu à sa partie supérieure de rainures parallèles aux fentes de capillarité et disposées entre celles-ci pour évacuer un excès de liquide de mouillage.According to another characteristic of the invention, the bar is provided at its upper part with grooves parallel to the capillary slots and arranged between them to evacuate an excess of wetting liquid.

Selon une autre caractéristique de l'invention le barreau est monté de façon amovible pour être enlevé de la cuve en cas de besoin.According to another characteristic of the invention, the bar is removably mounted to be removed from the tank if necessary.

Selon une autre caractéristique de l'invention, le barreau est en une matière thermoplastique par exemple injectée ce qui le rend simple à fabriquer et donc peu couteux.According to another characteristic of the invention, the bar is made of a thermoplastic material for example injected which makes it simple to manufacture and therefore inexpensive.

Selon encore une autre caractéristique de l'invention, le dispositif pour mouiller une bande souple comporte en outre un organe de guidage de la bande souple monté au dessus du barreau rigide pour l'application en pression de la bande sur la partie supérieure du barreau, cet organe de guidage étant pourvu d'une pluralité de nervures faisant face à la partie supérieure du barreau, chaque nervure s'étendant parallèlement aux fentes de capillarité sans leur faire face. Cette position des nervures par rapport aux fentes de capillarité permet de guider convenablement la bande souple tout en préservant une bonne qualité de transfert du liquide de mouillage à la bande souple, c'est à dire sans mouiller intempestivement la face non encollée de la bande souple.According to yet another characteristic of the invention, the device for wetting a flexible strip also comprises a member for guiding the flexible strip mounted above the rigid bar for applying the strip under pressure on the upper part of the bar, this guide member being provided with a plurality of ribs facing the upper part of the bar, each rib extending parallel to the capillary slots without facing them. This position of the ribs relative to the capillary slots makes it possible to guide the flexible strip properly while preserving a good quality of transfer of the wetting liquid to the flexible strip, that is to say without inadvertently wetting the unglued side of the flexible strip. .

Avantageusement, chaque nervure fait face à une rainure pour que l'application en pression de la bande souple sur le barreau soit réalisée aux endroits où il n'y a pas de transfert de liquide de mouillage à la bande souple afin de ne pas la détériorer.Advantageously, each rib faces a groove so that the pressure band of the flexible strip is applied to the bar in places where there is no transfer of wetting liquid to the flexible strip so as not to damage it. .

D'autres caractéristiques et avantages de l'invention apparaîtront encore mieux à la lecture de la description détaillée qui suit d'un exemple de réalisation de l'invention faite en référence aux dessins.Other characteristics and advantages of the invention will appear even better on reading the detailed description which follows of an exemplary embodiment of the invention made with reference to the drawings.

La figure 1 est une vue schématique de face, cuve coupée, du dispositif selon l'invention.Figure 1 is a schematic front view, cut tank, of the device according to the invention.

La figure 2 est une vue schématique en coupe selon II-II de la figure 1.FIG. 2 is a schematic sectional view along II-II of FIG. 1.

La figure 3 est une vue en perspective du barreau rigide selon l'invention.Figure 3 is a perspective view of the rigid bar according to the invention.

Sur les figures les mêmes références numériques désignent des éléments identiques.In the figures, the same reference numerals designate identical elements.

Sur la figure 1, le dispositif 1 pour mouiller une bande souple telle qu'une bande de papier 2 ayant une face au moins partiellement encollée, telle qu'une étiquette, comporte une cuve 3 dans laquelle est placé un barreau rigide 4, de forme sensiblement parallélélipédique ayant sa partie supérieure faisant saillie par rapport à l'ouverture de la cuve. Le barreau rigide 4 repose sur des plots 5 solidaires du fond de la cuve et est maintenu à ceux ci par l'intermédiaire de pions 6 fixés aux plots 5 et venant se loger à force dans des évidements 7 aménagés dans la partie inférieure du barreau. Selon cette disposition le barreau rigide est monté amovible pour pouvoir être enlevé de la cuve en cas de besoin.In FIG. 1, the device 1 for wetting a flexible strip such as a paper strip 2 having an at least partially glued side, such as a label, comprises a tank 3 in which is placed a rigid bar 4, of substantially parallelepiped shape having its upper part projecting from the opening of the tank. The rigid bar 4 rests on studs 5 integral with the bottom of the tank and is held to these by means of pins 6 fixed to the studs 5 and coming to be forced into recesses 7 arranged in the lower part of the bar. According to this arrangement, the rigid bar is removably mounted so that it can be removed from the tank if necessary.

La bande de papier entraînée de façon classique par un jeu de rouleaux et contre-rouleaux (non représentés) défile au dessus du barreau selon une direction de défilement et un sens représentés par la flèche f, la direction de défilement de la bande de papier étant perpendiculaire à l'axe longitudinal du barreau en place dans la cuve comme visible sur la figure 2. La face préalablement encollée de la bande de papier fait face à la partie supérieure du barreau rigide et vient en affleurement avec celle-ci.The strip of paper conventionally driven by a set of rollers and counter-rollers (not shown) scrolls above the bar in a direction of travel and a direction represented by the arrow f, the direction of travel of the paper strip being perpendicular to the longitudinal axis of the bar in place in the tank as shown in Figure 2. The previously glued side of the paper strip faces the upper part of the rigid bar and comes flush with it.

La partie supérieure du barreau est traversée, selon la direction de défilement de la bande de papier, par une pluralité de fentes de capillarité 8 sensiblement parallèles entre elles visibles sur la figure 3. Chaque fente de capillarité 8 débouche sur la face de dessus, la face avant et la face arrière du barreau. Bien entendu, on pourrait concevoir des fentes débouchant seulement sur la face du dessus et la face arrière du barreau (face droite du barreau visible sur la figure 2) pour obtenir le même effet.The upper part of the bar is crossed, in the direction of travel of the paper strip, by a plurality of capillarity slots 8 substantially parallel to one another visible in FIG. 3. Each capillary slot 8 opens onto the top face, the front and back of the bar. Of course, one could design slots opening only on the top face and the rear face of the bar (right side of the bar visible in Figure 2) to obtain the same effect.

La cuve 3 est remplie d'un liquide de mouillage tel qu'un liquide de dilution de la colle comme par exemple de l'eau, dont le niveau est maintenu constant par tout moyen adapté tel que décrit dans la demande de brevet EP 0293316, pour que le fond 9 des fentes baigne continuellement dans le liquide de mouillage.The tank 3 is filled with a wetting liquid such as an adhesive dilution liquid such as for example water, the level of which is kept constant by any suitable means as described in patent application EP 0293316, so that the bottom 9 of the slots continuously bathes in the wetting liquid.

Le barreau en forme de peigne, peut être réalisé en une matière thermoplastique injectée apte à amener par capillarité le liquide de mouillage du fond des fentes de capillarité jusqu'à la face supérieure du barreau. Il est placé transversalement par rapport au chemin d'avance de la bande de papier de manière que la partie supérieure de celui-ci, mouillée dudit liquide par capillarité, forme des lignes de collage sur la face encollée de la bande de papier, ces lignes de collage étant sensiblement parallèles entre elles et à la direction de défilement de la bande de papier.The comb-shaped bar can be made of an injected thermoplastic material capable of bringing capillarity the wetting liquid from the bottom of the capillary slots to the upper face of the bar. It is placed transversely to the path of advance of the paper strip so that the upper part thereof, wetted by said liquid by capillary action, forms bonding lines on the glued side of the paper strip, these lines of bonding being substantially parallel to each other and to the direction of travel of the paper strip.

Le barreau 4 est aussi pourvu à sa partie supérieure de rainures 10 parallèles aux fentes de capillarité 8 et disposées entre celles-ci. Comme visible sur les figures 1 et 3, les rainures sont moins larges que les fentes débouchantes de capillarité et aussi moins profondes pour obtenir une résistance suffisante du barreau rigide. Ainsi qu'on pourra le comprendre, chaque dent 11 du barreau formée entre deux rainures 10 et traversée par une fente 8 qui a une largeur très petite (de l'ordre de 1 mm) de sorte que les lignes de mouillage ont une largeur très petite mais suffisante pour assurer un collage convenable de la bande de papier. Le nombre de dents et de rainures est choisie en fonction de la largeur de la bande de papier et de la qualité du papier. Sur les figures, le barreau 4 comporte 8 fentes de capillarité 8 pour le mouillage d'une bande de papier dont la largeur est d'environ 3 cm. Le nombre de fentes et de rainures peut varier en fonction de la largeur de la bande de papier. La vitesse de défilement de la bande de papier, la hauteur du niveau de liquide de dilution de la colle par rapport au fond des fentes débouchantes de capillarité et la largeur de celles-ci permettent de faire varier la quantité d'eau déposée sur la face encollée de la bande de papier.The bar 4 is also provided at its upper part with grooves 10 parallel to the capillary slots 8 and disposed between them. As can be seen in FIGS. 1 and 3, the grooves are narrower than the through capillary slots and also less deep to obtain sufficient resistance from the rigid bar. As will be understood, each tooth 11 of the bar formed between two grooves 10 and crossed by a slot 8 which has a very small width (of the order of 1 mm) so that the mooring lines have a very wide small but sufficient to ensure proper bonding of the paper strip. The number of teeth and grooves is chosen according to the width of the paper strip and the quality of the paper. In the figures, the bar 4 has 8 capillary slots 8 for wetting a strip of paper whose width is approximately 3 cm. The number of slots and grooves may vary depending on the width of the paper strip. The speed of movement of the paper strip, the height of the adhesive dilution liquid level with respect to the bottom of the through capillary slits and the width of these make it possible to vary the amount of water deposited on the face glued with the paper strip.

Comme visible sur les figures 1 et 2, un organe de guidage de la bande de papier constitué d'une partie supérieure 12 et d'une partie inférieure 13 est fixé à la cuve 3 par des vis de fixation respectivement 14, 14', ces deux partie étant disposées de part et d'autre de la bande de papier 2. La partie supérieure 12 de l'organe de guidage qui est montée au dessus de la bande de papier, pour l'application en pression de la bande de papier sur la partie supérieure du barreau, est pourvue d'une pluralité de nervures 15 faisant face à la partie supérieure du barreau 4. Chaque nervure 15 s'étend parallèlement aux fentes débouchantes de capillarité 8 sans leur faire face et de préférence en vis-à-vis d'une rainure 10. La partie supérieure 12 de l'organe de guidage peut aussi être montée à articulation pour pouvoir pivoter entre une première position où elle est positionnée au-dessus de la bande de papier pour son application en pression sur la partie supérieure du barreau et une seconde position où elle forme un déflecteur empêchant la bande de papier de venir affleurer la partie supérieure du barreau.As can be seen in FIGS. 1 and 2, a member for guiding the paper strip consisting of an upper part 12 and a lower part 13 is fixed to the tank 3 by fixing screws 14, 14 'respectively, these two parts being arranged on either side of the paper strip 2. The upper part 12 of the guide member which is mounted above the paper strip, for the pressure application of the paper strip on the upper part of the bar is provided with a plurality of ribs 15 facing the upper part of the bar 4. Each rib 15 extends parallel to the through capillary slots 8 without facing them and preferably facing them screw of a groove 10. The upper part 12 of the guide member can also be hinged in order to be able to pivot between a first position where it is positioned above the paper strip for its application under pressure on the part upper part of the bar and a second position where it forms a deflector preventing the strip of paper from coming flush with the upper part of the bar.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation ci-dessus décrit et on pourra prévoir d'autres variantes sans pour cela sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment described above and we can provide other variants without departing from the scope of the invention.
