Abstract
Description
La présente invention concerne le domaine de la fabrication d'articles enroulés en carton à partir de l'assemblage par collage de bandes individuelles en carton et a pour objet un dispositif d'encollage de bandes en carton défilant en continu dans une installation de fabrication de tels articles enroulés et plus particulièrement d'articles en forme de tubes.The present invention relates to the field of the manufacture of rolled articles made of cardboard from the gluing assembly of individual cardboard strips and relates to a device for gluing cardboard strips running continuously in a production facility. such wound articles and more particularly of articles in the form of tubes.
On sait que dans une installation de fabrication de tubes en carton par enroulement de bandes en carton et collage de ces dernières les unes sur les autres, celles-ci sont délivrées simultanément en continu, selon un faisceau de bandes situées les unes au-dessus des autres et espacées les unes des autres, éventuellement avec un décalage horizontal des bandes entre elles. Un tel faisceau de bandes est délivré depuis un poste d'alimentation ou de déroulement, via une station d'encollage, jusqu'à un poste d'enroulement ou spiraleuse où les bandes sont enroulées en hélice de manière synchrone autour d'un mandrin destiné à la formation du tube en carton.It is known that in a plant for manufacturing cardboard tubes by winding cardboard strips and gluing them together, they are delivered simultaneously continuously, in a bundle of strips located above the others and spaced from each other, possibly with a horizontal offset of the bands between them. Such a bundle of strips is delivered from a feeding or unwinding station, via a sizing station, to a winding or spiral station where the strips are helically wound synchronously around a mandrel intended to to the formation of the cardboard tube.
On connaît différents types de stations d'encollage de bandes en carton dont certaines sont constituées par une cuve unique d'imprégnation, dans laquelle les bandes en carton sont immergées dans un bain de colle unique qui les imprègne de colle sur leurs deux faces.Various types of cardboard strip sizing stations are known, some of which consist of a single impregnation vat, in which the cardboard strips are immersed in a single adhesive bath which impregnates them with glue on their two faces.
Toutefois, les bandes en carton traversent la cuve d'imprégnation en étant guidées au moyen de guides spécifiques créant des points de déviation qui exercent des sollicitations mécaniques dans lesdites bandes altérant leurs fibres.However, the cardboard strips pass through the impregnation vessel by being guided by means of specific guides creating deflection points which exert mechanical stresses in said bands altering their fibers.
D'autres stations d'encollage proposent des solutions moins traumatisantes pour les bandes, qui consistent à déposer de la colle par le haut et par gravité sur la bande supérieure du faisceau, ladite colle s'écoulant par gravité en cascade sur les autres bandes, et à étaler ladite colle sous la forme d'un film recouvrant leur face supérieure grâce à des racleurs.Other sizing stations provide less traumatic solutions for the strips, which consists in depositing adhesive by the top and by gravity on the upper band of the bundle, said adhesive flowing by gravity in cascade on the other strips, and spreading said glue in the form of a film covering their upper face by means of scrapers.
Cependant, ces stations d'encollage ne permettent pas de réaliser un encollage des deux faces de la bande, ce qui nécessite de rajouter des étapes supplémentaires complexifiant d'autant lesdites stations et rallongeant les temps de fabrication. D'autre part, la quantité de colle déposée est expulsée de part et d'autre des bandes par les racleurs, ce qui entraîne des pertes excessives dues aux éclaboussures fréquentes et par conséquent des consommations importantes de colle. En outre, les projections de colle, et plus particulièrement de colle de silicate, peuvent avoir des effets sur la santé des opérateurs travaillant à proximité, ce qui nécessite une maîtrise de l'exposition sur le lieu de travail et le port d'équipements de protection appropriés.However, these sizing stations do not make it possible to glue both sides of the strip, which necessitates the addition of additional steps which make the said stations more complex and lengthen the manufacturing times. On the other hand, the amount of adhesive deposited is expelled on both sides of the strips by the scrapers, which causes excessive losses due to frequent splashing and consequent high consumption of glue. In addition, splashes of glue, and more particularly silicate glue, can have effects on the health of operators working nearby, which requires control of workplace exposure and the wearing of equipment. appropriate protection.
La présente invention a pour but de pallier ces inconvénients en proposant un dispositif d'encollage de bandes en carton permettant une meilleure maîtrise de la quantité de colle utilisée et une consommation de colle inférieure à celle des dispositifs actuels, tout en empêchant les projections de colle en dehors de la zone effective d'encollage.The object of the present invention is to overcome these drawbacks by proposing a device for gluing cardboard strips allowing a better control of the quantity of glue used and a glue consumption lower than that of the current devices, while preventing glue projections. outside the actual sizing area.
A cet effet, le dispositif d'encollage, selon la présente invention, de bandes en carton défilant en continu selon un faisceau de bandes, plus particulièrement, dans une ligne de fabrication d'articles enroulés et notamment de tubes en carton, se caractérise essentiellement en ce qu'il consiste en au moins une boîte d'encollage susceptible d'être traversée par ledit faisceau de bandes et renfermant au moins un espace d'encollage, permettant de réaliser un encollage desdites bandes dans une enceinte fermée empêchant les projections de colle en dehors dudit espace d'encollage.For this purpose, the sizing device, according to the present invention, of cardboard strips moving continuously in a strip of bundles, more particularly in a line of manufacture of rolled articles and in particular of cardboard tubes, is essentially characterized in that it consists of at least one gluing box capable of being traversed by said bundle of strips and containing at least one gluing space, making it possible to glue said strips into a closed enclosure preventing glue splashes outside said gluing space.

Les moyens d'étanchéité des ouvertures de passage 8 seront, de préférence, situés du côté aval des faces respectivement d'entrée et de sortie 7 correspondantes et pourront consister avantageusement en des joints d'étanchéité 9 à lèvres 10 déformables élastiquement, de manière à permettre le passage des bandes 1 en s'adaptant élastiquement à leur épaisseur, tout en assurant l'étanchéité desdites ouvertures de passage 8, avec ou sans passage desdites bandes 1.The sealing means of the
On peut voir également que les joints 9 sont maintenus grâce à des serre-joints 10' fixés sur les faces respectivement d'entrée et de sortie 7, côté aval.It can also be seen that the
La boîte d'encollage 2 pourra comporter avantageusement au moins une ouverture d'alimentation en colle, non représentée, destinée à alimenter constamment la cuve d'encollage 4 pour maintenir le niveau du bain de colle à un niveau maximum N (
D'autre part, la cuve d'encollage 4 pourra comprendre avantageusement une goulotte de trop plein 11 reliée à une goulotte de récupération de colle 12 (
La
Une surface de guidage horizontale 15 pourra consister en au moins deux barres ou rouleaux de guidage 16 fixés, de préférence, à l'une des faces internes de la boîte d'encollage 2 orientée sensiblement parallèlement au sens d'avancement du faisceau de bandes 1 dans ladite boîte d'encollage 2.A
Si on se réfère maintenant à la
Un bac individuel à colle 17 pourra avantageusement être constitué par un fond 18, reliant les deux barres ou rouleaux de guidage 16, de telle manière que ces derniers forment deux côtés latéraux dudit bac 17, tandis que les deux autres côtés latéraux dudit bac 17 pourront être fermés par des parois 19 s'étendant, de préférence, sensiblement parallèlement au sens d'avancement du faisceau de bandes 1 dans la boîte d'encollage 2.An
On comprendra alors que le niveau de colle dans un bac 17 devra atteindre sensiblement le bord supérieur des barres ou rouleaux de guidage 16 pour obtenir un contact d'encollage efficace des faces inférieures des bandes 1 avec la surface de la colle contenue dans les bacs individuels 17.It will then be understood that the level of adhesive in a
Le fond 2' de la boîte d'encollage 2 pourra avantageusement être conformé en pente vers des ouvertures d'évacuation 20 débouchant, de préférence, dans le au moins un espace de récupération 6, de manière à pouvoir évacuer les fuites et/ou excédents de colle tombant sur ledit fond 2', dans la goulotte de récupération de colle 12 située sous ledit fond 2' de la boîte d'encollage 2 (
Les figures montrent également que la boîte d'encollage 2 pourra comporter deux côtés opposés 21, 22, sensiblement perpendiculaires au sens d'avancement du faisceau de bandes 1, formant respectivement une face d'entrée 21 des bandes 1 dans ladite boîte d'encollage 2 et une face de sortie 22 des bandes 1 de ladite boîte d'encollage 2. En outre, pour permettre le passage des bandes 1 à travers les faces d'entrée 21 et de sortie 22 de la boîte d'encollage 2, une pluralité de fentes de passage 23 seront pratiquées dans lesdites faces d'entrée 21 et de sortie 22 en étant situées les unes au-dessus des autres et écartées les unes des autres, de sorte que chaque fente de passage 23 soit apte à permettre le passage d'une bande 1 du faisceau de bandes 1 traversant ladite boîte d'encollage 2.The figures also show that the
