Abstract
Description
La présente invention a pour objet un système électro-mécanique de centrage automatique des bandes de transporteurs à courroie en auge ou à plat. The present invention relates to an electro-mechanical system for automatic centering of conveyor belts in a trough or flat.
Le centrage des bandes de transporteurs à courroie est un élément important de leur bon fonctionnement. The centering of the belt conveyor belts is an important element of their proper functioning.
Ce centrage normal sur un transporteur à courroie dont ltossature et les éléments sont bien conçus peut, néanmoins, être mis en défaut par
. une alimentation excentrée des produits transportés,
. une mauvaise mise en sans fin de la bande au niveau du jonction
nement provoquant un défaut d'alignement de l'axe de la courroie
proprement dite,
. un encrassement des tambours et des rouleaux dus à un mauvais net
toyage du brin porteur.This normal centering on a belt conveyor whose frame and elements are well designed can, however, be faulted by
. an eccentric supply of the products transported,
. improper endless positioning of the strip at the junction
causing a misalignment of the belt axis
proper,
. fouling of drums and rollers due to poor cleaning
toy strand.
L'absence de centrage d'une bande en fonctionnement peut créer des désordres à l'alimentation-en provoquant la chute du produit sur le plancher ou sur le brin inférieur, ce qui en aggrave la mauvaise tenue. The lack of centering of a strip in operation can create feeding disorders - by causing the product to fall on the floor or on the lower strand, which worsens its poor performance.
I1 entrain également l'usure ou la déchirure des bords de la bande qui frotte sur les capots ou sur les éléments fixes de la structure métallique du transporteur. I1 also causes wear or tear of the edges of the strip which rubs on the covers or on the fixed elements of the metal structure of the conveyor.
Pour obtenir un centrage correct de la bande pendant le fonctionnement du transporteur a courroie, on utilise habituellement des stations à rouleaux montées sur pivots. verticaux et dont la rotation limitée dans le plan horizontal estiprcyoquéepar le déport de la bande agissant surdes- galets guides places sur des supports situés de part et d'autre de la station. In order to obtain correct centering of the belt during the operation of the belt conveyor, roller stations mounted on pivots are usually used. vertical and whose limited rotation in the horizontal plane is biased by the offset of the band acting on guide rollers placed on supports located on either side of the station.
Le recentrage de la bande est provoqué par la rotation de la station dont l'axe des rouleaux ne forment plus un angle droit avec l'axe longitudinal du transporteur. The re-centering of the belt is caused by the rotation of the station whose axis of the rollers no longer form a right angle with the longitudinal axis of the conveyor.
Ce système qui peut être placé sur le brin supérieur ou inférieur ne possède pas une triez grande efficacité, la composante dynamique devant provoquer le recentrage n'étant.pas toujours suffisante pour refaire concider l'axe de la bande avec l'axe du transporteur. This system which can be placed on the upper or lower strand does not have a high efficiency sort, the dynamic component having to cause the refocusing being not always sufficient to redo reconcile the axis of the belt with the axis of the conveyor.
Un autre système utilisant une station en auge inversée agissant uniquement sur le brin inférieur de la bande du transporteur à courroie est également utilise en complément ou en substitution du systeme de station sur pivot. Another system using an inverted trough station acting only on the lower strand of the belt of the conveyor belt is also used in addition to or in replacement of the pivot station system.
Le système est plus considéré comme un moyen d'empêcher le déport de la bande (ce qu'il ne réussit pas toujours à faire) que comme un moyen de recentrage d'une bande déportée. Elle n'a, de plus , rien d'automatique et demande des réglages réguliers. The system is considered more as a means of preventing the tape from being offset (which it does not always succeed in doing) than as a means of refocusing a deported tape. There is, moreover, nothing automatic and requires regular adjustments.
te but de l'invention est de proposer un système de station (3) sur pivot (2), en auge ou à plat suivant le profil de la bande, inclinée à 600 par rapport au plan matérialisé par le bat i du transporteur à courroie et dont la rotation est actionnée par vérin (5). The object of the invention is to propose a station system (3) on pivot (2), in trough or flat according to the profile of the strip, inclined at 600 relative to the plane materialized by the bat i of the belt conveyor. and the rotation of which is actuated by jack (5).
Situés avant la station (3) et placés de part et d'autre de la bande se trouvent deux capteurs de proximité capacitifs (8) et (7). Located before the station (3) and placed on either side of the strip are two capacitive proximity sensors (8) and (7).
Lorsque la bande en se déportant est détectée par l'un ou l'autre des capteurs, celui-ci active le vérin (5) par l'intermédiaire d'un contact. When the strip moving away is detected by one or other of the sensors, the latter activates the jack (5) via a contact.
Le vérin agit alors sur le levier (6) solidaire du pivot (2) de la station (3) la faisant pivoter dans le sens opposé au capteur et donc au déport. The jack then acts on the lever (6) integral with the pivot (2) of the station (3) causing it to pivot in the direction opposite to the sensor and therefore to the offset.
Le fait que la station soit inclinée à 600 provoque un soulàvement du rouleau latéral incliné de la station (3) situé du coté ou se fait le déport et simultanément un abaissement du rouleau incliné opposé ce qui, par voie de conséquence, fait revenir l'axe longitudinal de la bande en concordance avec l'axe longitudinal du transporteur. The fact that the station is inclined at 600 causes an uplift of the inclined lateral roller of the station (3) located on the side or is offset and simultaneously a lowering of the opposite inclined roller which, consequently, causes the longitudinal axis of the belt in agreement with the longitudinal axis of the conveyor.
Eh reprenant son alignement, la bande n'est plus détectée par le capteur de proximité, ce qui bascule le contact et fait revenir le vérin en position (a) soyenne. Resuming its alignment, the strip is no longer detected by the proximity sensor, which switches the contact and returns the cylinder to position (a) soyenne.
En agissant sur le levier solidaire (6) du pivot (2) de la station (3) il provoque sa rotation qui ramène celle-ci en position neutre (a). By acting on the integral lever (6) of the pivot (2) of the station (3) it causes its rotation which brings it back to the neutral position (a).
Ce systase peut s'adapter sur tous les transporteurs à courroie quelle que soit la largeur et la forte de l'auge ainsi que sur les bandes plates en adaptant le nombre et l'inclinaison des rouleaux. This systase can be adapted on all belt conveyors whatever the width and the strong of the trough as well as on the flat bands by adapting the number and the inclination of the rollers.
On peut également placer ces systèmes sur le brin de retour si nécessaire. These systems can also be placed on the return strand if necessary.
