Abstract

The includes a metallic flexible band made of an assembly of connecting spirals (3),connecting bars and lateral plates (4). The lateral plates are passed through in two points by each connecting bar (2). The lateral plates have a main body (5) with a curved edge (6) and an angle (7) parallel to the body plane. The angle (7) is made from a part of the body bottom to allow the overlapping of two consecutive plates and their connection by a common bar (8). The lateral plates are formed from a metal blank whose base is folded twice in a right angle to form the angle (7) parallel to the main body of the plate. One of the holes (9,10) for passage of the bars is oblong. The zone (11) connecting the body (5) and the angle (7) has a depth less than or at the most equal to the diameter of the belt spiral wires (3). USE/ADVANTAGE - Belts, used in high temperature conditions, are less susceptible to rupture at the connection between bars and plaques.

Description

La présente invention a pour objet un tapis transporteur métallique, en particulier utilisable dans des conditions de température élevées et de contraintes mécaniques sévères, tapis transporteur composé essentiellement d'une bande métallique articulée constituée par l'assemblage de spires métalliques de liaison, de barettes perpendiculaires au sens d'avancement du tapis et de plaquettes latérales. The present invention relates to a metal conveyor belt, in particular usable under conditions of high temperature and severe mechanical stress, conveyor belt essentially composed of an articulated metal band constituted by the assembly of metal connecting turns, perpendicular bars in the direction of advancement of the belt and side plates.

L'invention concerne plus particulièrement des tapis transporteurs pouvant être utilisés à très hautes températures, par exemple de 700" à 1200 C (ceci non limitativement) pour des traitements thermiques de matériaux en tout genre, généralement par passage de ceux-ci dans des fours tunnels. The invention relates more particularly to conveyor belts which can be used at very high temperatures, for example from 700 "to 1200 C (this without limitation) for thermal treatments of materials of all kinds, generally by passing them through ovens tunnels.

On comprendra néanmoins que l'invention peut être transposée à tout type de tapis, indépendamment du type de maillage.It will nevertheless be understood that the invention can be transposed to any type of carpet, regardless of the type of mesh.

De manière générale, ces tapis transporteurs sont entrainés par cylindres et par adhérence ou par friction. On ne reviendra pas ultérieurement sur cet aspect, secondaire en l'espèce et connu de l'homme de l'art. Generally, these conveyor belts are driven by cylinders and by adhesion or friction. We will not come back to this aspect, secondary in the present case and known to those skilled in the art.

Ces tapis transporteurs sont généralement réalisés en acier réfractaire. En raison des conditions élevées de température, il se produit une dilatation inévitable et répétée des différents composants du tapis, ce qui entraine à la longue des ruptures de certaines pièces. En effet, les tapis connus comportent des pièces soudées, ce qui entraine une modification structurelle de l'acier, donc des risques de rupture au niveau desdites soudures. C'est le cas en particulier au niveau de la liaison entre les barrettes et les plaquettes latérales. These conveyor belts are generally made of refractory steel. Due to the high temperature conditions, there is an inevitable and repeated expansion of the different components of the carpet, which in the long term leads to ruptures of certain parts. Indeed, known belts have welded parts, which causes a structural modification of the steel, therefore risks of rupture at said welds. This is particularly the case at the connection between the bars and the side plates.

En effet, les barrettes sont soudées en un point haut sur les plaquettes correspondantes. La barrette comporte donc un retour vertical dont l'extrémité est soudée sur la plaquette. Ainsi la dilatation de la tringle entraine un basculement de la plaquette en direction du tapis, donc une détérioration et souvent une rupture des plaquettes. Indeed, the bars are welded at a high point on the corresponding plates. The bar therefore has a vertical return, the end of which is welded to the plate. Thus the expansion of the rod causes the plate to tilt in the direction of the belt, therefore deterioration and often rupture of the plates.

De plus, les retours verticaux sont en fait des aspérités qui risquent d'accrocher les rebords contre lesquels défile le tapis transporteur, d'où des risques supplémentaires de détérioration. In addition, the vertical returns are in fact asperities which risk catching the edges against which the conveyor belt scrolls, hence additional risks of deterioration.

On a déjà proposé de remédier à ces inconvénients par la demande de brevet 90 15266, au nom de la demanderesse. It has already been proposed to remedy these drawbacks by patent application 90 15266, in the name of the applicant.

Dans cette structure, on propose un tapis transporteur métallique en particulier utilisable dans des conditions de température élevées et de contraintes mécaniques sévères, tapis transporteur composé essentiellement d'une bande métallique articulée constituée par l'assemblage de spires métalliques de liaison, de barrettes perpendiculaires au sens d'avancement du tapis et de plaquettes latérales, caractérisé en ce que les barrettes sont articulées chacune sur deux trous oblongs de deux plaquettes adjacentes qui se chevauchent au niveau de ladite articulation, les barrettes étant désolidarisées des plaquettes et étant reliées deux à deux, selon un pas déterminé, par des pontets de matière situés de l'autre côté du tapis par rapport aux plaquettes.  In this structure, a metal conveyor belt is provided, in particular usable under conditions of high temperature and severe mechanical stress, a conveyor belt essentially composed of an articulated metal strip formed by the assembly of metallic connecting turns, bars perpendicular to the direction of advancement of the mat and side plates, characterized in that the bars are each articulated on two oblong holes of two adjacent plates which overlap at the level of said articulation, the bars being separated from the plates and being linked in pairs, according to a determined pitch, by bridges of material located on the other side of the mat relative to the plates.

Bien que cette structure apporte un progrès notable, les résultats ne sont pas totalement satisfaisants et on note encore des ruptures au niveau des pontets. Although this structure brings significant progress, the results are not completely satisfactory and there are still ruptures in the bridges.

La présente invention a pour but de remédier à ces différents inconvénients. The object of the present invention is to remedy these various drawbacks.

Conformément à l'invention, on propose en effet un tapis transporteur métallique, en particulier utilisable dans des conditions de température élevées et de contraintes mécaniques sévères, tapis transporteur composé essentiellement d'une bande métallique articulée constituée par l'assemblage de spires métalliques de liaison, de barettes perpendiculaires au sens d'avancement du tapis et de plaquettes latérales, caractérisé en ce que les plaquettes latérales sont traversées en au moins deux points par chaque barette de liaison. In accordance with the invention, a metal conveyor belt is in fact proposed, in particular usable under conditions of high temperature and severe mechanical constraints, conveyor belt essentially composed of an articulated metal band constituted by the assembly of metal connecting turns , bars perpendicular to the direction of travel of the mat and side plates, characterized in that the side plates are crossed at at least two points by each connecting bar.

De préférence, les plaquettes latérales seront constituées d'un flan métallique dont la base est repliée deux fois à angle droit pour former un retour parallèle au corps principal de la plaquette. Preferably, the side plates will consist of a metal blank whose base is folded twice at right angles to form a return parallel to the main body of the plate.

On comprendra mieux l'invention à l'aide de la description ci-après d'un mode non limitatif de mise en oeuvre, en référence à la figure unique annexée qui est une vue en perspective partielle d'un tapis transporteur conforme à l'invention. The invention will be better understood with the aid of the description below of a non-limiting mode of implementation, with reference to the attached single figure which is a partial perspective view of a conveyor belt conforming to the invention.

Le tapis (1) comporte principalement: - des barettes (2) perpendiculaires au sens d'avancement du tapis, - des spires (3) constituant la partie support du tapis, - des plaquettes latérales (4). The carpet (1) mainly comprises: - bars (2) perpendicular to the direction of advancement of the carpet, - turns (3) constituting the support part of the carpet, - side plates (4).

Selon l'invention les plaquettes latérales comportent un corps principal (5), éventuellement courbé en (6) et un retour (7) sensiblement parallèle au plan du corps (5). According to the invention the side plates comprise a main body (5), possibly curved at (6) and a return (7) substantially parallel to the plane of the body (5).

Le retour sera réalisé sur seulement une partie de la base du corps pour permettre le chevauchement de deux plaquettes consécutives et donc leur liaison par une barette commune (8). The return will be made on only a part of the base of the body to allow the overlapping of two consecutive plates and therefore their connection by a common bar (8).

Pour rattraper les jeux dus aux déformations de température et pour permettre l'enroulement sur les tambours, I'un des trous (9,10) de passage des barettes dans les plaquettes sera de forme oblongue. To make up for the play due to temperature deformations and to allow winding on the drums, one of the holes (9, 10) for the passage of the bars in the plates will be of oblong shape.

II est en outre essentiel que la zone de liaison (11) entre le corps (5) et le retour (7) ait une profondeur inférieure ou au plus égale au diamètre de fils de spire du tapis pour éviter toute saillie en dessus du tapis. It is also essential that the connection zone (11) between the body (5) and the return (7) has a depth less than or at most equal to the diameter of the turns of the carpet to avoid any projection above the carpet.

On comprendra que cette par structure les plaquettes sont maintenues en deux points par les barettes, ce qui est bien entendu préférable à un maintien en un seul point comme précédemment. It will be understood that this structure by platelets are held at two points by the bars, which is of course preferable to a maintenance at a single point as above.

Les plaquettes seront rendues solidaires des barettes par soudure (12) de l'extrémité des barettes sur le retour, ou par une boule de soudure (13) indépendante du retour (5). Les deux principes pouvant être utilisés en alternance. The plates will be made integral with the bars by welding (12) from the end of the bars on the return, or by a solder ball (13) independent of the return (5). The two principles can be used alternately.

On peut également au lieu de la boule de soudure (13) prévoir un écrasement mécanique (pinçage) de l'extrémité de la barette.  It is also possible, instead of the solder ball (13), to provide a mechanical crushing (pinching) of the end of the bar.

De préférence la plaquette sera obtenue par estampage et pliage d'une plaque métallique unique. On ne sortirait pas du cadre de l'invention en réalisant une plaquette à partir de deux ou trois pièces différentes assemblées par soudure.  Preferably the plate will be obtained by stamping and folding a single metal plate. It would not go beyond the ambit of the invention to produce a wafer from two or three different parts assembled by welding.
