Abstract
Description
Les bandes transporteuses sont généralement plates sur leur face inférieure et sont entraînées et tournent autour de tambours cylindriques. La bande est alors instable transversalement et, pour chercher à assurer un centrage automatique de la bande, on a donné aux tambours une forme ovoïde ou conique. The conveyor belts are generally flat on their underside and are driven and rotate around cylindrical drums. The strip is then unstable transversely and, in order to seek to ensure automatic centering of the strip, the drums have been given an ovoid or conical shape.
Ce moyen est efficace lorsque la bande est beaucoup plus longue que large, en raison de ltélasticité des fils de chaine, mais donne beaucoup moins satisfaction dans le cas des bandes larges par rapport à leur longueur. This means is effective when the strip is much longer than wide, due to the elasticity of the warp threads, but gives much less satisfaction in the case of wide strips compared to their length.
Dans ce cas, on a proposé de garnir la face intérieure de la bande d'un ou de plusieurs profils longitudinauxs qui trouvent leur place dans des gorges pratiquées dans les tambours. Ce moyen est efficace lorsque les bandes sont peu tendues, mais dès qu'est appliquée a la bande une tension appréciable, les forces~transversales au mouvement deviennent considérables au moindre désalignement des tambours. In this case, it has been proposed to fill the inner face of the strip with one or more longitudinal profiles which find their place in grooves made in the drums. This means is effective when the bands are slightly stretched, but as soon as an appreciable tension is applied to the band, the forces ~ transverse to the movement become considerable at the slightest misalignment of the drums.
La présente invention vise à remédier à la naissance de ces forces, et, par là, à obtenir un alignement parfait des bandes transporteuses. The present invention aims to remedy the birth of these forces, and thereby obtain a perfect alignment of the conveyor belts.
A cet effet, l'invention prévoit, contrairement à ce qui s'observe dans une bande classique, de ne pas confier à la carcasse de la bande l'ensemble des fonctions de cette bande, a savoir le port du produit, le déplacement dans une direction déterminée et la transmission de la puissance nécessaire à ce travail et d'associer des éléments spécifiques à leur fonction propre. To this end, the invention provides, contrary to what is observed in a conventional band, not to entrust to the carcass of the band all the functions of this band, namely the wearing of the product, the movement in a determined direction and the transmission of the power necessary for this work and to associate specific elements with their own function.
Or on sait que la transmission de la puissance, le mouvement et le guidage sont très bien assurés par des moyens mécaniques tels que courroies trapézoidales et poulies, et que le port du produit l'est également par des toilesvprotégées ou non par un élastomère. Now, we know that the transmission of power, movement and guidance are very well ensured by mechanical means such as V-belts and pulleys, and that the wearing of the product is also carried out by fabrics protected or not by an elastomer.
Compte tenu de ce qui précède, la bande transporteuse selon l'invention est constituée par un revêtement élastomère déposé -sur une toile déformable longitudinalement, par exemple en tissu gommé, éventuellement à tissage à 450 et munie sur sa face inférieure d'au moins un profil longitudinal en élastomere d'extensibilité minimale, par exempte de section trapézordalepet d'une nappe de câbles de traction au droit du profil. In view of the above, the conveyor belt according to the invention consists of an elastomeric coating deposited on a longitudinally deformable fabric, for example of gummed fabric, optionally woven at 450 and provided on its underside with at least one longitudinal profile in elastomer of minimum extensibility, for example trapezoidal section of a sheet of traction cables to the right of the profile.
On voit queydans cette bande, ses différentes fonc
tions sont confies a des éléments spécifiques de ces fonctions et sans que naissent, au passage du profil sur la poulie à gorge inscrite dans le tambour, des forces de cisaillement pouyant aboutir à la rupture, étant donné que c'est le profil seul qui est conçu pour offrir ltex-
tensibilcé minimale, la toile étant déformable longitudinalement.We see that in this strip, its different functions
tions are entrusted to specific elements of these functions and without the emergence, on passing of the profile on the grooved pulley inscribed in the drum, of shear forces which can lead to rupture, since it is the profile alone which is designed to offer ltex-
minimum tensile strength, the fabric being longitudinally deformable.
A titre nullement limitatif, on a représenté sur les figures du dessin annexé, trois exemples de réalisation de bandes transporteuses selon l'invention, ces figures étant des vues partielles en coupe transversale dans la zone des profils longitudinaux. By way of non-limiting example, there are shown in the figures of the appended drawing, three embodiments of conveyor belts according to the invention, these figures being partial views in cross section in the area of the longitudinal profiles.
Dans L'exempLe de la fig. 1, la bande comporte un tissu gommé 1 dont le tissage est disposé à 45 pour permettre sa déformation longitudinale. I1 est revêtu d'une couche 2 de matière élastomère. Le guidage et la puissancesont assurés par la courroie trapézoldale 3 traversée lon- gitudinalement par des câbles de traction 4. Bien entendu il peut être prévu plusieurs courroies. In the example of fig. 1, the strip comprises a gummed fabric 1, the weaving of which is arranged at 45 to allow its longitudinal deformation. I1 is coated with a layer 2 of elastomeric material. The guiding and the power are ensured by the trapezoidal belt 3 traversed lengthwise by traction cables 4. Of course, several belts can be provided.
Dans l'exemple de la fig. 2, la bande a la même struc
ture que celle de la fig. 1 et les éléments analogues portent les mêmes chiffres de référence. Toutefois, ici, la nappe de câbles de traction 4 est disposée dans la cou che de revêtement porteur 2.In the example of fig. 2, the band has the same struc
ture than that of fig. 1 and the like have the same reference numerals. However, here, the sheet of traction cables 4 is arranged in the layer of carrier coating 2.
Dans l'exemple de la fig. 3, il est prévu non seulement des nappes de câbles de traction disposés longitudinalement dans les profils 3comme dans l'exemple de la fig. 1, mais également une nappe 5 de câbles, non tissés, disposés
transversalement dans la couche de revêtement 2, au-dessus de la toile 1 qui peut entre ici en fils droits.In the example of fig. 3, it is not only provided with plies of traction cables arranged longitudinally in the profiles 3 as in the example of FIG. 1, but also a sheet 5 of cables, nonwoven, arranged
transversely in the covering layer 2, above the fabric 1 which can here enter straight wires.
Pour un meilleur fonctionnement des bandes selon l'invention, il peut être recommandé de créer un dégagement entre la face inférieure de la bande et le tambour afin que toute la tension passe par les profils t-rapézoldaux et qu'ils puissent donner ainsi leur plein effet de transmission de puissance et d'engagement dans les gorges des tambours. For a better functioning of the bands according to the invention, it may be recommended to create a clearance between the underside of the band and the drum so that all the tension passes through the t-rapézoldaux profiles and so that they can give their full effect of power transmission and engagement in the grooves of the drums.
D'autre part, cette absence de pression entre la partie porteuse du tapis et les tambours peut autoriser un certain-désalignement dans le parallélisme des tambours, dans les limites que peuvent permettre des courroies trapézoidales. Ce cas se présente notamment sur les machines mobiles dont le châssis ne présente pas toujours une rigidité rigoureuse. On the other hand, this absence of pressure between the load-bearing part of the belt and the drums can allow a certain misalignment in the parallelism of the drums, within the limits that V-belts can allow. This case arises in particular on mobile machines whose chassis does not always have rigorous rigidity.
