Description

Dispositif de maintien et de centrage automatique pour bande de couverture souple et étanche sur transporteurs courbes- L'invention se rapporte au domaine de la manutention en continu de matériaux en vrac par des convoyeurs équipés de bandes transporteuses souples sans fin. Plus particulièrement, l'invention concerne les bandes transporteuses souples sans fin rendues étanches aux éléments extérieurs tels que pluies, vents et pollution pour assurer la protection des matériaux transportés<B>et</B> susceptibles de confiner lesdits matériaux transportés tels que sels, produits pulvérulents, ciments ou céréales, pour garantir la protection des sites traversés. The invention relates to the field of continuous handling of bulk materials by conveyors equipped with endless flexible conveyor belts. More particularly, the invention relates to flexible endless conveyor belts sealed to the external elements such as rain, wind and pollution to protect the transported materials <B> and </ B> capable of conferring said transported materials such as salts, pulverulent products, cements or cereals, to guarantee the protection of the crossed sites.

Essentiellement, on connait, <B>à</B> ce jour, parmi les ensembles de manutention supposés offrir cette double étanchéité, d'une part vers l'intérieur de la bande transporteuse souple sans fin d'autre part vers l'exiérieur, des dispositifs tubulaires<B>de</B> bandes transporteuses souples (le plus souvent désignés par "pipe conveyor" ou "hose conveyor") ou des gaines mobiles susceptibles de contenir et de convoyer des matériaux, tels que ceux qui sont décrits dans les documents W09511848-A de DUNLOP ENERKA BV <B>et</B> FOERDEkANLANGEN MASCHINENBAU Gmbh ou FR2615836-A de MAREAU. Essentially, we know, <B> to </ B> today, among the handling sets supposed to offer this double seal, on the one hand towards the inside of the endless flexible conveyor belt on the other hand to the outside , tubular devices <B> of </ B> flexible conveyor belts (most often referred to as "pipe conveyor" or "hose conveyor") or mobile sheaths capable of containing and conveying materials, such as those described in the documents W09511848-A of DUNLOP ENERKA BV <B> and </ B> FOERDEKANLANGEN MASCHINENBAU GmbH or FR2615836-A of MAREAU.

Ces dispositifs présentent plusieurs inconvénients majeurs. Outre la réduction de capacité sectionnelle des bandes transporteuses, donc<B>de</B> débit qu'ils induisent, ils présentent des difficultés dans les moyens d'assurer une étanchéité efficace, laissant<B>de</B> ce fait, pénétrer les eaux de ruissellement<B>à</B> l'intérieur de la bande transporteuse souple et polluant les produits trarisportés, avec les conséquences que celà implique qu'il<U>s'agit</U> de matériaux sensibles<B>à</B> l'eau ou même<B>à</B> l'humidité tels que ciments, céréales, sucres ou sels. En effet, un des problèmes essentiels est de nature mécanique. Il s'agit moyens destinés au maintien de la bande transporteuse souple sans fin, sous sa forme tubulaire, comme, par exemple, dans le document FR2604983-A de JAPAN PIPE CONVEYOR et des moyens de fen-neture de la bande transporteuse souple sans fin sur elle-même ou celle de la couverture souple sur la bande transporteuse souple sans fin près du point de chargement et des moyens d'ouverture de ladite bande transporteuse souple sans fin près du de déchargement. Pour<B>y</B> pallier, le document FR'-)715538-A de SURRATEAU propose de faire glisser ladite bande transporteuse souple sans fin sur la paroi interne d'un support de bande lui aussi tubulaire, ce qui ne facilite pas les opérations<B>de</B> chargement et<B>de</B> déchargement. autre solution est offerte par le document FR2615836-A de MAREAU qui décrit une installation nécessitant non seulement un cible de<U>guidage</U> et de mise en forme de la bande transporteuse souple sans fin, mais aussi la présence<B>de</B> rainures<B>et</B> d'éléments saillants venant s'engrener pour fermer la bande transporteuse souple sans fin au dessus du câble. These devices have several major disadvantages. In addition to reducing the sectional capacity of the conveyor belts, hence the <B> of </ B> flow they induce, they present difficulties in the means of ensuring an effective seal, leaving <B> of </ B> in this way penetrate runoff <B> to </ B> within the flexible conveyor belt and pollute the transported products, with the consequences that this implies that <U> is </ U> of sensitive materials <B> to </ B> water or even <B> to </ B> moisture such as cements, grains, sugars or salts. Indeed, one of the essential problems is of a mechanical nature. These are means intended for holding the endless flexible conveyor belt, in its tubular form, as for example in document JAPAN PIPE CONVEYOR FR2604983-A and means for closing the endless flexible conveyor belt. on itself or that of the flexible blanket on the endless flexible conveyor belt near the loading point and means for opening said endless flexible conveyor belt near the unloading station. For <B> y </ B> mitigate, the document FR '-) 715538-A SURRATEAU proposes to slide said endless flexible conveyor belt on the inner wall of a tubular support also tubular, which facilitates not the <B> operations of </ B> loading and <B> of </ B> unloading. Another solution is offered by FR2615836-A MAREAU which describes an installation requiring not only a target <U> guiding </ U> and shaping the endless flexible conveyor belt, but also the presence <B> </ B> grooves <B> and </ B> of protruding elements coming into mesh to close the endless flexible conveyor belt over the cable.

<B>De</B> manière similaire,<B>le</B> document FR270172-A de POIVRE, bien que l'installation qu'il décrit ne nécessite pas<B>de</B> cible mais des rouleaux pour former la bande transporieuse souple sans fin en forme<B>de</B> tube, propose des dents sur les bordures longitudinales<B>de</B> la bande umuporteuse souple sans fin pour permettre leur engrènement. <B> From </ B> the PEIVRE document FR270172-A, although the installation it describes does not require <B> of </ B> target but rolls to form the endless flexible conveyor belt in <B> form of </ B> tube, offers teeth on the longitudinal edges <B> of </ B> the endless flexible conveyor belt to allow their meshing.

Pour pallier ces inconvénients et, en particulier pour réduire les coûts élevés<B>de</B> maintenance, dus<B>à</B> la nécessité d'utiliser des dispositifs mécaniques plus ou moins complexes de mise en forme<B>de</B> tuyau ou d'ouverture et de fermeture de la bande transporteuse souple sans fin, le document DE4138780-A, de PHOENIX AG, propose une bande transporteuse souple, utilisant un dispositif sans rouleaux consistant en un ou plusieurs éléments de guidage, tels que bandes, plaques ou rails, constitué(s) d'un matériau antifriction, polytétrafluoréthylène ou polyéthylène. Bien que relativement simple dans son principe, ce dispositif ne permet pas d'éNiter une réduction de la capacité sectionnelle <B>de</B> la bande souple, donc du débit<B>de</B> l'installation, puisque son fonctionnement, sous forme<B>de</B> tuyau, ne permet pas une utilisation de la bande transporteuse souple sans fin sous forme d'auge semi-circulaire profonde. To overcome these drawbacks, and in particular to reduce the high maintenance costs, due to the need to use more or less complex mechanical shaping devices <B> <B> to </ B>, the need to use more or less complex mechanical shaping devices <B > from </ B> hose or opening and closing of the endless flexible conveyor belt, the document DE4138780-A, from PHOENIX AG, proposes a flexible conveyor belt, using a device without rollers consisting of one or more elements of guiding, such as strips, plates or rails, made of antifriction material, polytetrafluoroethylene or polyethylene. Although relatively simple in principle, this device does not allow to eliminate a reduction in the sectional capacity <B> of </ B> the flexible band, therefore the flow <B> of </ B> the installation, since its operation, in the form of <B> of </ B> hose, does not allow a use of the endless flexible conveyor belt in the form of deep semicircular trough.

Une autre tentative de solution est décrite dans le document JP10120136-A <B>de</B> BA!,#'DO CHEMCAL INDUSTRY Lid qui propose une bande<B>à</B> couverture destinée<B>à</B> éviter l'utilisation des dispositifs mécaniques complexes d'assemblage et de séparation de la bande transporteuse de sa bande de couverture. Pour ce faire, elle nécessite forme particulière, dite "défomiée" de la bande de couverture dont les bords sont recouverts d'une bande intermédiaire de dureté supérieure<B>à</B> celle<B>de</B> la bande elle-même et surtout une circulation d'air entre la bande transporteuse et sa bande de couverture, ce nécessite, aussi, une installation délicate et fragile. Dans le but d'éviter que les matériaux transportés sous forme de tube n'adhèrent aux parois de la bande, la société RAYNERI a proposé, dans le document FRI-0373472-A, un dispositif connecté, lui aussi,<B>à</B> une source d'air comprimé. Another attempt at solution is described in JP10120136-A <B> of </ B> BA!, # 'DO CHEMCAL INDUSTRY Lid which proposes a band <B> to </ B> cover intended <B> to </ B> Avoid the use of complex mechanical devices for assembling and separating the conveyor belt from its cover strip. To do this, it requires a special form, called "defomie" of the cover strip whose edges are covered with an intermediate band of hardness greater than <B> to </ B> the <B> of </ B> the band itself and especially a circulation of air between the conveyor belt and its cover band, it also requires a delicate and fragile installation. In order to prevent the materials transported in the form of a tube from adhering to the walls of the strip, the company RAYNERI proposed, in the document FRI-0373472-A, a device connected, also <B> to < / B> a source of compressed air.

Outre les inconvénients<B>déjà</B> cités, les systèmes précédemment décrits sont, également, tout<B>à</B> fait inefficaces lorsque le convoyeur arrive en limite de pente pour matériau transporté.In addition to the aforementioned drawbacks, the previously described systems are also ineffective when the conveyor reaches the edge of the slope for transported material.

C'est pour cette raison que le document FR2469365-A de HASHIMOTO propose l'utilisation d'une bande transporteuse souple sans fin comportant, dans sa part' interne, des éléments séparateurs destinés<B>à</B> empêcher le glissement des produits lorsque la pente s'accroît. Si cette disposition peut s'avérer utile, elle a l'inconvénient de nécessiter l'emploi de bandes spéciales, Le brevet déposé par F.VALCALDA <B>N'</B> 9904430<B>'</B> pour une bande transporteuse souple sans finjonctionnant en auge semi-circulaire Profonde<B>-</B> bande de couverture souple étanche,, satisfait<B>à</B> la fois le double critére d'étanchéité.,, les contraintes de simplicité mécanique de quidage,d'ouverture et de fermeture et celles de la capacité sectionnelle maximale de<B>1</B> bande souple sans fin,pour assurer un débit maximal- Toutefois.,les dispositifs de maintien et de guidage de la bande de couverture,ne permettent pas aux transporteurs qui en sont équipés, de prendre des virages sur le plan horizontal sans qu'il<B>y</B> ait ssociation entre.la bande porteuse,vide ou remplie de matériaux et la bande de couverture- Lé proble'6me technique consiste donc dans la réalisation d'un spositif de maintien et de centrage automatique de la bande de couverture souple sàns fin,sur la bande porteuse-lorsque cette dernière#,soumise dans les virages sur plan horizontal<B>à</B> des efforts centripétes,tend a quitter l'axe tansversal de la station porteuse et<B>à</B> remonter le long du rouleau de rive prévu acet effet- Le but de<B>1</B> invention est donc de proposer un dispositif de maintien et de centrage automatique de la bande de couverture(l) qui suive le mouvement latéral de la bande porteuse, sans fin et en auge profonde(2). <B>Z7</B> reposant ses rouleaux porteurs,(3) de manière<B>à</B> assurer une parfaite coordination de mouvement entre les deux bandes- Fig:1/2/3- Torsque la bande porteuse vide Fig:l lorsque le bande porteuse est<B>à</B> X% de sa charge maximale Fig:2 lorsque la bande porteuse est<B>à</B> sa charge maximale Fig:3 Et soumise aux effets d'une force centripète (4) Là :4 montre une vue complété du dispositif de maintien et de centrage automatique- il constitué d'un axe-support transversal(5)solidaire du bâti du transporteur(6)ou de la guirlande(8)constituée par les rouleaux(3)- Il supporte un boitier central(9)dont le réglage transversal par rapport<B>à</B> l'axe a-b.peut être assuré par tous moyens me'caniques tel que "tendeurs<B>à</B> lanternes"<B>(10)</B> permettant son déplacement transversal p"ar rapport<B>à</B> l'axe a-b Lé boitier central(9) permet<B>à</B> l'ensemble de maintien et centrageOli, composé de rouleaux(12) dont le diamkre et la longueur vari en fonction de la largeur des bandes et de la vitesse du transporteur- Ces rouleaux(12)sont mobiles en azimut et fixes en site par rapport à.la piece centrale unique(<B>13)</B> qui,en fonction de son altitude,controlée par la reglétte verticale(14) permet<B>à</B> l'ensemble de mainti et de centrage(ll) de rester au contact de la bande de couverture(l) quelle que soit la position de celle-çi,lors des déplacements latéraux de bande porteuse(2)- Là- <B>:5</B> Montre le détail du boitier central(9)et de la pi- centrale unique(13)réunis par un maillon permettant un déplacement pièce dans le plan transversal- reglette(14)peut,en raison le sa fente longitudinale,se mouvoir autour de l'axe(15)en rotation et en altitude- Sa liberté de mouvement e-n rotation et en altitude étant limitée par des butées réglables(16)- Le mouvement vertical de l'ensemble est induit Vers bas, par le poids de l'ensemble mobile (reglette-piéce-centrale rouleaux<B>)</B> Vers le haut,par <B>1</B> bande de couverture et en fonction de position engendrée par le taux de remplissage de la bande porteuse entre la marche <B>à</B> vide et la marche au taux de remplissage maximal<B>(</B> debit maximum du transporteur<B>) -</B> Le dispositif de ntien et de centrage précédemment décri a pour caractéristique ncipale l'automatisme donné de part sa liberté de mouvement,en altitude,du fait du déplacement controlé de la reglette(14) par le boitier central(9)lui même solidaire par l'intermédi re de l'axe- support(5)du bâti du transporteur(6)ou de la guirlande<B>(8)</B> rouleaux(3) et de la possibilité de déplacements angulaires,en azimut, rouleaux presseurs(12),de suivre tous les mouvements latérauxde l'ensemble bande porteuse(2)-bande de couverture(l)- Le déplacement latéral du dispositif étant imposé par la forme prise par la bande de couvertureMet les butées que constituent arrondis d'accrochages(17)situés de part et d'autre de la bande de couverture(l) <B>y</B> dans sa liaison avec la bande porteuse(2) Fig 4<B>-</B> It is for this reason that HASHIMOTO document FR2469365-A proposes the use of an endless flexible conveyor belt having, in its internal part, separating elements intended to prevent the sliding of produced when the slope increases.
