Abstract

Overhead (cable transport) method using a cable 2, and a belt 1 whose lateral edges include notches 5 collaborating with flexible magnets and adhesively bonded onto the edges in order to permit the closure of the belt around the cable, thus forming a flexible tube. The belt is reopened upstream of the unloading station in order to be separated from the cable and to wind around the end pulley which has a vertical axis. The transported product is discharged just upstream of the end station by sliding transversely to the belt and downwards, where the side of the belt edge is smooth on the face in contact with the product. Moreover, the vertical axis configuration of the end pulley solves the problem of reversal of the belt on the return side.

Description

On sait qu'il existe différents moyens pour réaliser un convoyeur faisant collaborer une bande de caoutchouc avec un ou plusieurs cables acier. En général, le ou les cables assurent la fonction tracteur-porteur alors que la bande, qui est solidaire du ou des cables, assure le portage du produit.We know that there are different ways to make a conveyor by collaborating a rubber band with one or more steel cables. In general, the cable or cables provide the tractor-carrier function while the band, which is integral with the cable or cables, ensures the carrying of the product.

On connait tout d'abord les dispositifs mettant en oeuvre un ou plusieurs profilés de caoutchouc solidaires de la bande et destinés à maintenir la bande sur le ou les cables.We firstly know the devices using one or more rubber profiles integral with the strip and intended to hold the strip on the cable or cables.

Ces profilés peuvent se classer en plusieurs types:
- les profilés entourant complètement le ou les cabines. These profiles can be classified into several types:
- the profiles completely surrounding the cabin (s).

- les profilés entourant les cables mais comportant une fente
longitudinale permettant d'insérer les cables au moment du
montage de l'appareil convoyeur.- the profiles surrounding the cables but having a slot
longitudinal allowing cables to be inserted when
mounting of the conveyor device.

- les profilés n'entourant que partiellenent le ou les cables
de telle sorte que le ou les cables sont directement en
contact avec les galets supports évitant ainsi de faire
subir de forte pression au profilé.- the profiles only partially surrounding the cable (s)
so that the cable (s) are directly in
contact with the support rollers thus avoiding making
undergo strong pressure on the profile.

On connait enfin le dispositif n'utilisant qu'un seul cable supportant une bande par l'intermédiaire d'un profilé faisant corps-avec la bande en sa partie haute. La bande à une section dite en goutte d'eau et comporte un dispositif longitudinal sur un de ses flancs, permettant l'ouverture et la fermeture en vue du chargement et déchargement du produit à transporter.Finally, the device is known which uses only one cable supporting a strip by means of a profile forming a body with the strip in its upper part. The strip has a so-called teardrop section and has a longitudinal device on one of its sides, allowing opening and closing for loading and unloading of the product to be transported.

Tous ces procédés ou dispositifs comportent des stations d'extrémité comportant des tambours autour desquels le ou les cables effectuent une demi-rotation. Deux cas se présentent; soit le profilé reste solidaire du cable,soit celui-ci est désolidarisé du cable avant le passage autour du tambour.All these methods or devices include end stations comprising drums around which the cable or cables make a half-rotation. Two cases arise; either the profile remains secured to the cable, or the latter is detached from the cable before passing around the drum.

Dans le premier cas, le profilé caoutchouc subit une forte pres- s-ion entre le cable et la gorge du tambour.In the first case, the rubber profile undergoes a strong pressure between the cable and the groove of the drum.

Dans le second cas, le profilé subit une déformation pour sé séparer du cable.In the second case, the profile undergoes deformation to separate from the cable.

Enfin dans tous les cas existants, la bande comporte une géo- trie complexe de par son ou ses profils
Par ailleurs, ces dispositiSs ou procédés permettent de refermer la bande après chargement;Selon les cas, cette fermeture est plus ou moins étanche.Finally, in all existing cases, the strip has a complex geometry due to its profile (s)
Furthermore, these arrangements or methods make it possible to close the strip after loading; depending on the case, this closure is more or less sealed.

La présente invention vise à éliminer l'obligation de bande à géométrie complexe tout en apportant une solution de contournement des stations d'extrémité permettant d'éviter les surpressions sur le caoutchouc et par ailleurs, d'éviter le retournement de bande destiné à-laisser le côté sali coté supérieur de la bande retour.The present invention aims to eliminate the obligation of strip with complex geometry while providing a solution for bypassing the end stations making it possible to avoid overpressure on the rubber and moreover, to avoid the reversal of the strip intended for leaving the dirty side on the upper side of the return strip.

Comme le montre la figure 1 , la bande 1j de section rectangulaire, se referme autour du cable 2 après son chargement.As shown in Figure 1, the strip 1j of rectangular section, closes around the cable 2 after loading.

Sur la même figure, onrvoit que la bande est soulagée par des rouleaux 3 permettant entre autres au galet 4 de terminer l'e- pération de fermeture de la bande.In the same figure, it can be seen that the strip is relieved by rollers 3 allowing inter alia the roller 4 to complete the closing operation of the strip.

Sur la figure 2, on voit une coupe du cable 2 et de la partie supérieure de la bande 1, après le galet 4.In FIG. 2, we see a section of the cable 2 and of the upper part of the strip 1, after the roller 4.

Les bords latéraux de la bande la et lb , sont découpés en créneaux longitudinaux 5 afin que les deux bords la, lb, s'encastrent l'un dans l'autre.The lateral edges of the strip 1a and 1b are cut into longitudinal slots 5 so that the two edges 1a, 1b fit into one another.

Des aimants souples 6, 7, solidaires respectivement de la et b, sont en contact pour maintenir l'extrême bord de lb. Ils ne participetdonc pas directement > l'effort tangentiel de glissement des deux bords de bande.Flexible magnets 6, 7, respectively secured to la and b, are in contact to maintain the extreme edge of lb. They do not therefore participate directly> the tangential sliding force of the two edges of the strip.

La figure 5 montre en vue de dessus. l'ensemble d'une station.Figure 5 shows a top view. an entire station.

Le cable 2 quitte sa poulie de tension et éventuellement motrice 8, pour venir prendre en charge le bord de bande la en en collaboration avec le galet 9 muni d'une encoche 10 , fig.3 alors que le bord b est maintenu juste en aval par les galets 11, 12 dans une position verticale.The cable 2 leaves its tension and possibly driving pulley 8, to take over the edge of the strip 1a in collaboration with the roller 9 provided with a notch 10, fig.3 while the edge b is held just downstream by the rollers 11, 12 in a vertical position.

Les rouleaux 13, 14, ont préalablement guidé le bord de bande la en collaboration avec les rouleaux 3a, 3b , pour l'amener en position sous le galet 9.The rollers 13, 14 have previously guided the edge of the strip 1a in collaboration with the rollers 3a, 3b, to bring it into position under the roller 9.

Encore en aval, fig. 1 et coupe de la fig.4 , la poulie 4 positionne le bord b en recouvrement sur le bord la.Still downstream, fig. 1 and section of fig.4, the pulley 4 positions the edge b overlapping on the edge la.

La fig. 5 montre le rambour 5 destiné au contournement de la bande 1 . Ce contournement se fait bande à plat contre la périphérie du tambour. La fig. 6 montre une vue en élévation dans laquelle on peut voir le bord la de la bande descendre et se retourner progressivement en se rapprochant du tambour '15 pour se retrouver complètement dépliée à la tangente du tambour ,'dont l'axe est vertical.Fig. 5 shows the drum 5 intended for bypassing the strip 1. This bypass is made flat strip against the periphery of the drum. Fig. 6 shows an elevational view in which we can see the edge la of the strip go down and turn gradually while approaching the drum '15 to find itself completely unfolded at the tangent of the drum, 'whose axis is vertical.

On peut voir aussi le point de déchargement 16 ou le produit glisse sur la face hors encoche du bord la pour quitter la bande.We can also see the unloading point 16 where the product slides on the non-notched side of the edge 1a to leave the strip.

Le cable 2 est, de par sa tension importante et son maintien à la tangente de la poulie 8 , maintenu à la hauteur correspondant au point d'épure nécessaire au niveau des galets 9 et 4.The cable 2 is, by virtue of its high tension and its retention at the tangent of the pulley 8, maintained at the height corresponding to the necessary point of cleaning at the level of the rollers 9 and 4.

La différence de trajectoire des bords la et lb, au voisinage du tambour 15, bien visible sur la fig. 6 , est compensée par l'élasticité de la bande1 qui à cet effet, ne comporte pas de fibre rigide.The difference in trajectory of the edges 1a and 1b, in the vicinity of the drum 15, clearly visible in FIG. 6, is compensated for by the elasticity of the band 1 which for this purpose does not comprise a rigid fiber.

ainsi, le procédé d'ouverture et fermeture de bande lié au dispositif de tambour à axe vertical, permet d'éviter comme dans la pratique courante, le retournement de bande mettant le coté souillé par le produit transporté, à l'intérieur du tube que forme la bande fermée sur le coté retour.thus, the band opening and closing process linked to the vertical axis drum device, makes it possible to avoid, as in current practice, the turning of the band putting the soiled side by the transported product, inside the tube that forms the closed band on the return side.

Le dispositif de fermeture de la bande, fig. 2 , sert à la fois a rendre le tube-bande étanche tout en tenant lieu d'interface de maintien de la bande sur le cable.The tape closing device, fig. 2, is used at the same time to make the tube-tape watertight while taking the place of the interface for holding the band on the cable.

En variante, plusieurs cables peuvent être disposés cote à cote pour collaborer au maintien de la bande.Alternatively, several cables can be arranged side by side to collaborate in maintaining the strip.

En seconde variante, le dispositif d'accrochage des deux bords de bande peut être assuré par le collage de deux profilés en U ,est a dire un sur chaque bord de bande, de telle sorte qu'ils se présentent tEte-bêche en vue de s'emboîter longitudinalement.In the second variant, the device for hooking the two strip edges can be ensured by the bonding of two U-shaped profiles, that is to say one on each strip edge, so that they are presented head to tail in order to fit longitudinally.

En troisième variante, afin de respecter la symétrie concernant la distance de parcours des bords de bande, le point de rencontre des deux bords sieffectue à la hauteur de l'axe1? fig.6 de la bande. In a third variant, in order to respect the symmetry concerning the distance of travel of the edges of the strip, the meeting point of the two edges is carried out at the height of the axis1? fig. 6 of the strip.

On peut remarquer sur la figure 6 que le bord de bande la comporte ses encoches 5 ainsi que sa bande aimantée 6 sur la face qui n'est pas en contact avec le produit transporté. It can be seen in FIG. 6 that the edge of the strip 1a has its notches 5 as well as its magnetic strip 6 on the face which is not in contact with the product transported.

Au niveau des supports de ligne, fig.7, le cable 2 est supporté atravers la bande 1 par des courroies l8 elles-mêmes supportées par des galets l9
Cette configuration permet d'offrir une grande surface de contact évitant ainsi que la bande 1 ne supporte une forte pression.At the level of the line supports, fig. 7, the cable 2 is supported over the strip 1 by belts l8 themselves supported by rollers l9
This configuration makes it possible to offer a large contact surface thus preventing the strip 1 from supporting a high pressure.

Ces courroies peuvent être continuées de telle sorte que, par des galets appropriés, le même brin serve à la fois pour le côté aller et le côté retour de la bande 1 et ce, sur le pylône considéré.These belts can be continued so that, by suitable rollers, the same strand serves both for the forward side and the return side of the strip 1 and this, on the pylon considered.

Cette dernière disposition permet de réaliser l'équipotentialité des forces de tension au niveau des cables 2 pour les brins aller et retour. This latter arrangement enables the equipotentiality of the tension forces to be achieved at the level of the cables 2 for the outward and return strands.
