Abstract

The mechanism comprises a roller (1) running on a belt (8). The roller is fixed on a lever (2), and the ensemble is held in contact with the belt by means of a spring (3). When the belt is displaced laterally the lever is subjected to a lateral push from right to left. This action forces a spindle (4) held in two bearings (5) to turn slightly from the right top the left, driving forwards or backwards a return roller (7) support (6). The length and shape of the lever are such that a slight spring pressure is sufficient to hold the roller in rubbing contact with the belt.

Description

La présente invention concerne un dispositif à installer sur un transporteur à bande pour permettre à celle-ci de se maintenir dans l'axe dudit transporteur,sans avoir recours à une source d'énergie extérieure. Il s'agit d'un support mobile pour rouleau inférieur communément appelé "rouleau de retour". The present invention relates to a device to be installed on a conveyor belt to allow it to be maintained in the axis of said conveyor, without having to resort to an external source of energy. It is a movable support for lower roll commonly called "return roller".

Le maintient de cette bande se fait traditionnellement en av ançant ou en reculant l'une des extrémités de ce rouleau. Cette opération s'éffectue manuellement,plusieurs fois par jour,d'oû la nécéssité d'une maintenance permanente. En effet ce rouleau est monté à ses deux extrémités sur supports fixes boulonnés et l'opérateur est obligé de déboulonner réguliérement l'un des deux supports pour repositionner convenablement la bande. The maintenance of this strip is traditionally done by advancing or retreating one of the ends of this roller. This operation is carried out manually, several times a day, hence the need for permanent maintenance. In fact, this roller is mounted at its two ends on bolted fixed supports and the operator is obliged to unbolt regularly one of the two supports in order to reposition the strip properly.

Le dispositif selon l'invention,permet de remédier à cet inconvénient. Il se compose,en effet,selon ses propres caractéristiques,d'un axe tournant sur deux paliers oû sont fixés:un levier qui suit le déplacement latéral de la bande,et un support qui maintient l'une des deux extrêmités du rouleau de retour concerné. Ainsi quand la bande se déplace d'un coté du transporter, le rouleau,maintenu par le support fixe à l'une de ses extrêmités,voit son autre extrêmité,fixée sur le support mobile, avancer en même temps que ce dernier support, ou reculer quand la bande se déplace de l'autre coté,permettant ainsi à la bande d'être toujours maintenue dans l'axe du transporteur. The device according to the invention overcomes this drawback. It consists, in fact, according to its own characteristics, of an axis rotating on two bearings where are fixed: a lever which follows the lateral movement of the strip, and a support which holds one of the two ends of the return roller concerned. Thus when the band moves on one side of the conveyor, the roller, held by the fixed support at one of its ends, sees its other end, fixed on the mobile support, advancing at the same time as this latter support, or back off when the belt moves to the other side, thus allowing the belt to always be kept in line with the conveyor.

Selon les modes particuliers de réalisation,un galet sera fixé au bout du levier pour frotter sur la bande; Un ressort sera prévu pour maintenir le galet en contact avec la bande,le levier fera tourner l'axe légérement dans un sens ou dans l'autre,et le support rouleau se déplacera d'avant en arriére entrainant avec lui l'extremité de ce rouleau. According to the particular embodiments, a roller will be fixed at the end of the lever to rub on the strip; A spring will be provided to keep the roller in contact with the strip, the lever will rotate the axis slightly in one direction or the other, and the roller support will move from front to back causing with it the end of this roller.

Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.

La figure 1 représente en vue de face le dispositif selon l'invention. La figure 2 représente en vue de dessus ce dispositif. Figure 1 shows a front view of the device according to the invention. Figure 2 shows a top view of this device.

La figure 3 représente une coupe de ce dispositif.Figure 3 shows a section of this device.

En référence à ces dessins,le dispositif comporte un galet 1 fixé sur le levier 2 qui reste en contact avec la bande 8 grace à un ressort 3. Quand la bande se déplace latéralement,le levier suit et fait tourner légérement l'axe 4 qui est fixé sur deux paliers 5. Par ce mouvement de rotation de l'axe,le support 6 fait avancer ou reculer le rouleau 7. With reference to these drawings, the device comprises a roller 1 fixed on the lever 2 which remains in contact with the band 8 thanks to a spring 3. When the band moves laterally, the lever follows and slightly rotates the axis 4 which is fixed on two bearings 5. By this movement of rotation of the axis, the support 6 causes the roller 7 to move forward or backward.

La longueur du levier et sa forme sont telles q'une faible pression du ressort suffit pour tenir le galet en contact avec la bande. The length of the lever and its shape are such that a low pressure of the spring is enough to hold the roller in contact with the band.

Selon une variante non illustrée,les paliers qui tiennent l'axe,peuvent êtres remplacés par des bagues en bronze,ou toute autre matiére suivant les conditions d'environnement (milieux acides,chaleur,poussiéres et agréssivités diverses). According to a variant not illustrated, the bearings which hold the axis, can be replaced by bronze rings, or any other material depending on the environmental conditions (acidic environments, heat, dust and various aggressiveness).

Ce dispositif étant destiné à être monté sur tous types de transporteurs,ses dimensions et sa forme pourront changer suivant la structure du transporteur concerné.  This device being intended to be mounted on all types of carriers, its dimensions and shape may change depending on the structure of the carrier concerned.
