Abstract
Description
La présente invention concerne un arbre dit arbre à friction qui est destiné à recevoir les mandrins sur lesquels viennent s'enrouler des bandes de matériau tel que du papier. Ces arbres sont conçus de façon à permettre un glissement des bobines du matériau en bandes lors de l'enroulement de ce matériau sur les mandrins correspondants de façon à assurer une compensation des différences de tension dans les bandes et de diamètre des bobines. The present invention relates to a so-called friction shaft which is intended to receive the mandrels on which strips of material such as paper are wound. These shafts are designed so as to allow the coils of the material to slide in strips during the winding of this material on the corresponding mandrels so as to compensate for the differences in tension in the strips and in diameter of the coils.
Les arbres à friction actuellement disponibles sur le marché pour une telle application comprennent généralement arbre proprement dit, entraîné en rotation par tout moyen approprié et destiné à recevoir les mandrins des bobines, ces mandrins, généralement en carton, étant positionnés sur des bagues de serrage enfilées sur l'arbre et sur lesquelles s'exerce le glissement. Ces arbres à friction connus comportent en outre des barres de friction qui sont disposées longitudinalement sur l'arbre de manière que leur surface extérieure soit au contact de la surface interne des bagues de serrage. The friction shafts currently available on the market for such an application generally comprise the shaft itself, driven in rotation by any suitable means and intended to receive the mandrels of the reels, these mandrels, generally made of cardboard, being positioned on threaded clamping rings. on the tree and on which the sliding is exerted. These known friction shafts also have friction bars which are arranged longitudinally on the shaft so that their outer surface is in contact with the inner surface of the clamping rings.
La présente invention se propose de perfectionner ce type d'arbre à friction selon la technique antérieure en le simplifiant, en le rendant plus fiable et en en améliorant le rendement en permettant des couples élevés et en admettant des poids de bobines importants. The present invention proposes to improve this type of friction shaft according to the prior art by simplifying it, by making it more reliable and by improving the yield by allowing high torques and by admitting significant coil weights.
En conséquence, cette invention concerne un arbre à friction pour bobines, recevant des bandes de matériau tel que notamment du papier, conçu de façon à permettre un glissement des bobines sur l'arbre pendant l'enroulement du matériau en bandes afin de compenser notamment les différences de tension et de diamètre, caractérisé en ce qu'il comporte des barres de friction longitudinales, positionnées dans des logements débouchant sur des fentes ménagées dans la surface dudit arbre et qui soumettent à une friction directe les mandrins sur lesquels s 'enroulent lesdites bobines au moyen de vessies, interposées respectivement entre la surface inférieure de chaque barre de friction et le fond du logement correspondant et soumises à une pression d'air déterminée de manière à appliquer lesdites barres contre la surface interne respective de chaque mandrin. Consequently, this invention relates to a friction shaft for reels, receiving strips of material such as in particular paper, designed so as to allow the reels to slide on the shaft during the winding of the material in strips in order to compensate in particular for the differences in tension and diameter, characterized in that it comprises longitudinal friction bars, positioned in housings opening onto slots formed in the surface of said shaft and which subject the cores on which said coils are wound to direct friction by means of bladders, interposed respectively between the lower surface of each friction bar and the bottom of the corresponding housing and subjected to an air pressure determined so as to apply said bars against the respective internal surface of each mandrel.
Selon un mode de réalisation préféré de cette invention, chaque barre de friction directe présente une section droite en forme de T, la barre de ce T étant positionnée dans ledit logement débouchant sur ladite fente et étant soumise à l'action de ladite vessie. According to a preferred embodiment of this invention, each direct friction bar has a T-shaped cross section, the bar of this T being positioned in said housing opening onto said slot and being subjected to the action of said bladder.
Selon 1 invention, chaque barre de friction directe est réalisée en une matière plastique, de préférence en polyuréthane. According to 1 invention, each direct friction bar is made of a plastic material, preferably polyurethane.
Selon un autre exemple de réalisation de cette invention applicable plus particulièrement lorsque l'arbre ntest pas garni de mandrins sur toute sa longueur, on peut remplacer l'une des barres de friction directe par des barrettes interposées entre les mandrins et maintenant latéralement ces derniers. According to another embodiment of this invention applicable more particularly when the shaft is not lined with mandrels over its entire length, one can replace one of the direct friction bars with bars interposed between the mandrels and holding them laterally.
D'autres autre caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence au dessin annexé qui en illustre des exemples de réalisation dépourvus de tout caractère limitatif. Sur le dessin
- la figure 1 est une vue schématique en élévation latérale d'un premier exemple de réalisation d'un arbre à friction directe selon la présente invention
- la figure 2 est une coupe selon 2-2 de la figure 1, à échelle agrandie destinée à illustrer le montage des barres de friction directe dans l'arbre à friction objet de la présente invention et
- la figure 3 est une vue schématique similaire à la figure 1 illustrant un second exemple de réalisation de l'arbre à friction directe objet de l'invention.Other other characteristics and advantages of the present invention will emerge from the description given below with reference to the appended drawing which illustrates exemplary embodiments thereof without any limiting character. On the drawing
- Figure 1 is a schematic side elevational view of a first embodiment of a direct friction shaft according to the present invention
FIG. 2 is a section on 2-2 of FIG. 1, on an enlarged scale intended to illustrate the mounting of the direct friction bars in the friction shaft which is the subject of the present invention, and
- Figure 3 is a schematic view similar to Figure 1 illustrating a second embodiment of the direct friction shaft object of the invention.
On se réfère en premier lieu aux figures 1 et 2 qui illustrent un premier exemple de réalisation de l'arbre à friction directe selon l'invention dont toute la longueur est garnie de mandrins 10, par exemple en carton sur lesquels vient s'enrouler un matériau en bandes tel que notamment du papier. Firstly, reference is made to FIGS. 1 and 2 which illustrate a first embodiment of the direct friction shaft according to the invention, the entire length of which is furnished with mandrels 10, for example made of cardboard on which is wound a strip material such as in particular paper.
Comme on le voit clairement sur la figure 2, l'arbre 12, de forme cylindrique est muni de barres de friction longitudinales telles que 14 qui sont positionnées dans des logements tels que 16 ménagés dans la surface de l'arbre 12. Dans l'exemple de réalisation illustré par le dessin, chacune des barres de friction 14 présente un profil en forme de T et la barre de ce T maintient la barre de friction dans le logement 16, la surface extérieure de chaque barre 14 faisant saillie au travers de la fente 16' débouchant sur le logement 16 de manière que cette surface extérieure soit au contact des différents mandrins tels que 10 enfilés sur l'arbore 12. De préférence, les barres de friction directe telles que 14 sont réalisées en matière plastique telle que du polyuréthane. As clearly seen in Figure 2, the shaft 12, of cylindrical shape is provided with longitudinal friction bars such as 14 which are positioned in housings such as 16 formed in the surface of the shaft 12. In the exemplary embodiment illustrated by the drawing, each of the friction bars 14 has a T-shaped profile and the bar of this T maintains the friction bar in the housing 16, the external surface of each bar 14 projecting through the slot 16 'leading to the housing 16 so that this external surface is in contact with the different mandrels such as 10 threaded on the arbor 12. Preferably, the direct friction bars such as 14 are made of plastic material such as polyurethane .
Chacune des barres de friction directe 14 est soumise à un effort radial grâce à la présence d'une vessie gonflable telle que 18 interposée dans chaque logement 16 entre la surface inférieure de la barre de friction 14 et le fond du logement 16 (voir la figure 2). Each of the direct friction bars 14 is subjected to a radial force thanks to the presence of an inflatable bladder such as 18 interposed in each housing 16 between the bottom surface of the friction bar 14 and the bottom of the housing 16 (see figure 2).
L'arbre à friction directe décrit ci-dessus peut fonctionner selon deux méthodes
10 - Méthode à pression fixe
Chacune des vessies telles que 18 est gonflée selon une pression prédéterminée par l'intermédiaire d'une valve et l'enroulement du matériau en bandes sur les différents mandrins tels que 10 s'effectue sous pression constante.The direct friction shaft described above can operate in two ways
10 - Fixed pressure method
Each of the bladders such as 18 is inflated to a predetermined pressure by means of a valve and the material is wound in strips on the different mandrels such as 10 is carried out under constant pressure.
20 - Méthode avec variation de pression durant le
fonctionnement
Les différentes vessies telles que 18 sont gonflées par l'intermédiaire d'un raccord tournant au moyen d'un mano-détendeur de précision. L'arbre 12 qui est recouvert sur toute sa longueur par les mandrins tels que 10 est mis en pression par l'intermédiaire des différentes vessies 18 en affichant à chaque fois une pression différente compte tenu du matériau des bobines, de la largeur de ces dernières et de leur diamètre. La friction s'effectue alors directement sur les barres telles que 14.20 - Method with pressure variation during
operation
The various bladders such as 18 are inflated by means of a rotating connector by means of a precision pressure regulator. The shaft 12 which is covered over its entire length by the mandrels such as 10 is pressurized by means of the different bladders 18, each time displaying a different pressure taking into account the material of the coils, the width of the latter and their diameter. The friction then takes place directly on the bars such as 14.
Bien entendu, il est nécessaire que les mandrins soient retenus à chaque extrémité de l'arbre 12 par des bagues de retenue telles que 20, 20'. Of course, it is necessary that the mandrels are retained at each end of the shaft 12 by retaining rings such as 20, 20 '.
Dans le second exemple de réalisation de l'invention illustré par la figure 2 l'arbre 12 n'est pas garni sur toute sa longueur de mandrins 10 recevant les bobines telles que B. Dans cette application on remplace l'une des barrettes de friction par une barrette de guidage interchangeable telle que 22 qui est interposée entre deux mandrins successifs et qui permet de maintenir latéralement ces mandrins. Ces barrettes 22 sont interchangeables depuis l'extérieur et il en existe une pour chaque largeur de mandrins. Par ailleurs le fonctionnement de ce second exemple de réalisation est similaire à celui décrit ci-dessus en référence aux figures 1 et 2. In the second embodiment of the invention illustrated in FIG. 2, the shaft 12 is not filled over its entire length with mandrels 10 receiving the coils such as B. In this application, one of the friction bars is replaced. by an interchangeable guide bar such as 22 which is interposed between two successive mandrels and which allows these mandrels to be held laterally. These bars 22 are interchangeable from the outside and there is one for each width of mandrels. Furthermore, the operation of this second exemplary embodiment is similar to that described above with reference to FIGS. 1 and 2.
Parmi les avantages apportés par l'arbre à friction directe objet de l'invention, on peut citer notamment
- un prix de revient relativement peu important
- la possibilité d'admettre tous les diamètres des mandrins courants
- la possibilité de recevoir toutes les quantités de mandrins possibles
- l'admission de poids élevés
- l'aptitude à l'admission de couples élevés de la même manière qu'un arbre pneumatique classique.Among the advantages provided by the direct friction shaft which is the subject of the invention, there may be mentioned in particular
- a relatively low cost price
- the possibility of admitting all the diameters of the current chucks
- the possibility of receiving all the quantities of possible chucks
- admission of high weights
- the ability to admit high torques in the same way as a conventional pneumatic shaft.
I1 demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés mais qu'elle en englobe toutes les variantes. I1 remains of course that the present invention is not limited to the embodiments described and shown but that it encompasses all variants.
