Abstract
Description
L'invention a pour objet un transporteur à bande dont le profil des rebords autorise une fermeture simplifiée. The invention relates to a conveyor belt whose profile edges allow simplified closure.
Ce type de transporteur à bande est destiné à transporter des produits solides tels que minerai, tout venant, gravier, etc. ou pâteux tels que du béton, boue de papeterie, sur des distances variables, de très courtes (intérieur usine) à des distances très importantes, et dans ce cas la traversée des vallées ou de combes. De par sa grande capacité de survol, il intègre les accidents de terrain. This type of belt conveyor is intended for transporting solid products such as ore, general materials, gravel, etc. or pasty, such as concrete, stationery mud, over variable distances, from very short (factory interior) to very large distances, and in this case crossing valleys or valleys. Due to its great overflight capacity, it integrates accidents on the ground.
La présente invention concerne les transporteurs à bande et permet de véni cule r, de faSon continue, des produits divers, quels que soient la distance, le débit, le profil de l'installation, ainsi que la densité et la nature des matériaux. The present invention relates to belt conveyors and makes it possible to continuously sample various products, whatever the distance, the flow rate, the profile of the installation, as well as the density and the nature of the materials.
Dans les systèmes connus de ce genre, les bandes transporteuses sont constituées par des tapis sans fin armés, de longueurs différentes et reposant sur des rouleaux transversaux. In known systems of this kind, the conveyor belts are constituted by endless reinforced belts, of different lengths and resting on transverse rollers.
Ceux-ci sont répartis sur toute la longueur et suivant la charge, aussi bien dans la "zone de transport" que dans la partie retour de bande où leur espacement est différent. These are distributed over the entire length and according to the load, both in the "transport zone" and in the tape return part where their spacing is different.
Leurs extrémités comportent généralement d'un côté, un tambour "moteur" et de. l'autre un tambour de renvoi, avec plusieurs dispositifs de tension possibles. Their ends generally include on one side a "motor" drum and. the other a return drum, with several possible tensioning devices.
Les appareils ainsi conçus nécessitent des infrastructures importantes pour supporter les rouleaux, ce qui conduit, à un coût élevé, des installations. The devices thus designed require significant infrastructure to support the rollers, which leads, at a high cost, to installations.
Par ailleurs, dans le cas de passage au droit de terrains très accidentés et pour des distances importantes, il est impératif d'adapter des supports au profil de ces terrains. In addition, in the case of passing over very uneven terrain and for large distances, it is imperative to adapt supports to the profile of these terrains.
Il en résulte une grande complexité d'implantation et de réalisation des éléments fixes. This results in a great complexity of installation and production of the fixed elements.
Dans un autre mode de réalisation illustré par les documents US 1.530.707 et 2.925.903 la bande transporteuse est soutenue par des câbles et l'on prévoit des agrafes qui solidarisent de loin en loin la bande et les câbles. In another embodiment illustrated by documents US 1,530,707 and 2,925,903 the conveyor belt is supported by cables and staples are provided which fasten the belt and the cables from time to time.
Suivant une autre réalisation illustrée par le document US 3.326.354 les rebords de la bande sont directement surmoulés sur les câbles. Bien entendu, un tel agencement ne peut se réaliser que pour des bandes courtes. On sait que les câbles subissent des contraintes de torsion qui entraînent leur vrillage surtout si les portées sont longues. Ce vrillage se transmet, bien entendu, à la bande qui est déformée si bien qu'on peut assister à des décharges intempestives des produits transportés. Mais dans tous les cas, la bande est soumise à des efforts qui nuisent à sa longévité, malgré les articulations existant entre elle et les agrafes. According to another embodiment illustrated by document US 3,326,354 the edges of the strip are directly overmolded on the cables. Of course, such an arrangement can only be achieved for short strips. We know that cables undergo torsional stresses which cause their twisting especially if the spans are long. This twist is transmitted, of course, to the strip which is deformed so that one can witness untimely discharges of the products transported. But in all cases, the strip is subjected to stresses which harm its longevity, despite the articulations existing between it and the staples.
Enfin, il existe aussi des bandes transporteuses dont les bords sont suspendus à des crochets qui roulent dans des chemins de roulement. Cette disposition nécessite donc des superstructures coûteuses que les convoyeurs à câbles de suspension ont éliminées. Finally, there are also conveyor belts, the edges of which are suspended from hooks which roll in raceways. This arrangement therefore requires costly superstructures which the suspension cable conveyors have eliminated.
L'état de la technique peut également être définie par les demandes de breve ts suivantes:
- n0 88 03009 du 7 mars 1988,
- nO 88 05493 du 22 avril 1988,
- nO 88 07276 du 30 mai 1988,
- nO 88 07277 du 30 mai 1988.The state of the art can also be defined by the following patent applications:
- n0 88 03009 of March 7, 1988,
- No. 88 05493 of April 22, 1988,
- No. 88 07276 of May 30, 1988,
- No. 88 07277 of May 30, 1988.
Ces différentes demandes de brevets d'invention décrivent des transporteurs à bande dont la nouveauté réside notamment dans le ou les câbles et/ou dans les moyens de fermeture de la bande. These various patent applications describe belt conveyors, the novelty of which resides in particular in the cable or cables and / or in the means for closing the band.
Ces différents moyens de fermeture ainsi décrits assurent une fermeture parfaite et étanche. Ce type de fermeture convient pour des produits lourds ou des produits réclamant une étanchéité de fermeture parfaite. Or, dans un grand nombre de cas, la bande peut hêtre fermée à des endroits spécifiques et simplement protégée dans sa partie supérieure ou son ouverture dans tous les autres passages. These different closure means thus described ensure perfect and sealed closure. This type of closure is suitable for heavy products or products requiring a perfect seal. However, in a large number of cases, the strip may be closed in specific places and simply protected in its upper part or its opening in all the other passages.
L'invention tend à résoudre ces problèmes. Les moyens de fermeture, selon l'invention assure une fermeture souple de la bande transporteuse sans maintien des bords serrés. Cette solution est beaucoup plus simple et plus économique. Cette solution s'applique bien entendu aussi bien auxtransporteurs à bande dont les câbles sont en acier ou en matériau composite. The invention tends to solve these problems. The closure means according to the invention ensures flexible closure of the conveyor belt without keeping the edges tight. This solution is much simpler and more economical. This solution applies of course as well to belt conveyors whose cables are made of steel or composite material.
A cet effet, le transporteur à bande, selon l'invention, comporte, au niveau de ses rebords, des câbles qui sont logés dans les profilés des rebords. Lesdits profilés peuvent avoir une forme trapézoïdale. La grande base du trapèze est orientée vers l'intérieur de la bande. Lesdits rebords de la bande se prolongent par des rabats qui font office de bavette de protection pour protéger la partie supérieure ou ouverture de la bande. To this end, the conveyor belt according to the invention comprises, at its edges, cables which are housed in the profiles of the edges. Said profiles can have a trapezoidal shape. The large base of the trapezium is oriented towards the inside of the band. Said edges of the strip are extended by flaps which act as a protective flap to protect the upper part or opening of the strip.
Les dessins ci-joints sont donnés à titre d'exemples indicatifs et non limitatifs. Ils représentent un mode de réalisution préféré selon l'invention. Ils permettront de comprendre aisément l'invention. The attached drawings are given as indicative and non-limiting examples. They represent a preferred embodiment according to the invention. They will allow the invention to be easily understood.
La figure 1 est une vue de la bande du transporteur représentée à plat. Figure 1 is a view of the conveyor belt shown flat.
La figure 2 est une vue de la bande transporteuse en position fermée au niveau des rebords serrés entre eux. Figure 2 is a view of the conveyor belt in the closed position at the edges clamped together.
La figure 3 est une vue de la bande du transporteur représentée en position fermée souple uniquement par les.bavettes de protection. Figure 3 is a view of the conveyor belt shown in flexible closed position only by les.bavettes de protection.
La bande 1 comporte, au niveau de ses rebords 2, 3, les câbles 4 et 5 qui permettent sa traction et sa suspension. Ces câbles 4, 5 en acier ou en matériau composite sont logés dans des logements prévus dans les profilés 6, 7 desdits rebords 2, 3. The strip 1 comprises, at its edges 2, 3, the cables 4 and 5 which allow it to be pulled and suspended. These cables 4, 5 made of steel or of composite material are housed in housings provided in the profiles 6, 7 of said flanges 2, 3.
Les profilés 6, 7 ont une forme trapézoldale. Profiles 6, 7 have a trapezoidal shape.
La grande base est orientée vers l'intérieur de la bande 1. The large base is oriented towards the inside of the strip 1.
Lesdits rebords 2, 3 de la bande 1 se prolongent par des rabats 8, 9 qui font office -de bavette de protection pour protéger la partie supérieure ou ouverture 10 de la bande 1. Said edges 2, 3 of the strip 1 are extended by flaps 8, 9 which act as a protective flap to protect the upper part or opening 10 of the strip 1.
Comme on peut le voir dans la figure 2, la bande 1 est fermée hermétiquement en certains points tels qu'au passage des galets 11, 12. As can be seen in FIG. 2, the strip 1 is hermetically closed at certain points such as when the rollers 11, 12 pass.
Les galets 11, 12 rapprochent les rebords 2, 3 pour que leurs talons ou que les grandes bases viennent se serrer l'une contre l'autre pour fermer hermétiquement la bandé 1.The rollers 11, 12 bring the flanges 2, 3 together so that their heels or the large bases come to press against each other to hermetically seal the bandage 1.
Au contraire, dans la figure 3, il n'y a aucun galet qui puisse permettre le rapprochement des rebords 2, 3 de la bande. On the contrary, in FIG. 3, there is no roller which can allow the edges 2, 3 of the strip to be brought together.
Seul les rabats 8, 9 ferment sommairement le dessus 10 de la bande 1. Only the flaps 8, 9 close the top 10 of the strip 1 summarily.
Selon un autre mode de réalisation, les rabats de protection 2, 3 sont souples. According to another embodiment, the protective flaps 2, 3 are flexible.
Selon un autre mode de réalisation les rabats de protection 8, 9 sont préformés pour former deux plans inclinés de pente contraire pour faire office de toit de protection pour le contenu de la bande 1. According to another embodiment, the protective flaps 8, 9 are preformed to form two inclined planes of opposite slope to act as a protective roof for the contents of the strip 1.
