Abstract

The subject of the invention is a belt conveyor using a single cable, the said cable being metallic. The belt is completely closed on itself by virtue, in particular, of the profiles of its edges, characterised in that it uses a single cable 2 which fulfils both the function of supporting and the function of closing the belt 3; the monocable 2 is metallic; the profile of the edges 4, 5 of the belt 3 forms a housing 6 which permits twisting of the cable 2 without transmission of the twisting of the belt 3. Belt conveyor intended for conveying solid products.

Description

L'invention a pour objet un transporteur à bande utilisant un seul câble métallique. The invention relates to a conveyor belt using a single metal cable.

L'avantage de ce transporteur à bande, lorsque le câble est métallique, réside dans le fait que la bande est simple de conception et peut entre non armée. Il est possible d'utiliser un câble d'acier du commerce. Il peut utiliser un seul câble et le profil des rebords de la bande lui transmet l'action de la charge transportée tout en lui laissant la possibilité de vriller sans transmettre ce vrillage à la bande. The advantage of this belt conveyor, when the cable is metallic, lies in the fact that the band is simple in design and can be unarmed. It is possible to use a commercial steel cable. It can use a single cable and the profile of the edges of the strip transmits to it the action of the load transported while leaving it the possibility of twisting without transmitting this twist to the strip.

La présente invention concerne les transporteurs à bande et permet de véhiculer, de façon 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 convey, continuously, 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 on 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 to a high cost of the 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 ur,e grande complexité d'implantation et de réalisation des éléments fixes. This results in the great complexity of setting up and producing the fixed elements.

Dans un autre mode de réalisation illustré par les documents US 1.533.707 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 1,533,707 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, des torsions qui entrainent 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 stresses, twists 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 forces 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 être défini également par
- le brevet FR-A-2.519.944 GIMAR qui décrit une bande comportant deux talons latéraux qui enserrent les câbles de traction et de suspensions.The state of the art can also be defined by
- Patent FR-A-2,519,944 GIMAR which describes a band comprising two lateral heels which enclose the traction and suspension cables.

L'ensemble est tendu entre deux tambours. Les talons s'engagent dans des gorges du tambour et dans des gorges correspondantes du tambour. Ainsi, autour de ces tambours, le câble et les talons de la bande sont-ils rendus solidaires pour assurer un excellent entraSnement ?
- la demande de brevet déposée par la SARL ETUDES DE TRANSPORT le 7 mars 1988 sous le nO 88 03oye9. Ce dernier décrit un transporteur à bande utilisant des câbles de matériaux composites faisant partie intégrante de la bande et dont les rebords de la bande ont un profil tel qu'il permet le maintien de la bande fermée.The assembly is stretched between two drums. The heels engage in grooves of the drum and in corresponding grooves of the drum. Thus, around these drums, the cable and the heels of the band are made integral to ensure excellent training?
- the patent application filed by SARL ETUDES DE TRANSPORT on March 7, 1988 under the number 88 03oye9. The latter describes a conveyor belt using cables of composite materials forming an integral part of the band and whose edges of the band have a profile such that it allows the band to be kept closed.

Le transporteur à bande, selon l'invention, est du type utilisant un seul câble, ledit câble étant indépendant de la bande. The belt conveyor according to the invention is of the type using a single cable, said cable being independent of the belt.

Selon un mode de réalisation, le câble peut hêtre un câble métallique. According to one embodiment, the cable can be a metal cable.

Le profil des rebords de la bande forme un logement qui laisse la possibilité de vriller au câble sans transmettre ledit vrillage à ladite bande. Le verrouillage des rebords de la bande entre eux peut s'effectuer au moyen d'un verrouillage à lèvres, d'un verrouillage par tenons et mortaises (sans frottements), d'un verrouillage par emboitement (avec frottements). The profile of the edges of the strip forms a housing which leaves the possibility of twisting the cable without transmitting said twist to said strip. The edges of the strip can be locked together by means of a lip lock, a tenon and mortise lock (without friction), a socket lock (with friction).

Les dessins ci-joints sont donnés à titre d'exemples indicatifs et non limitatifs. Ils représentent un mode de réalisation 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.
