Abstract

The subject of the invention relates to a device permitting the rapid replacement of conveyor rollers. It consists of the inversion of a notch 16, 17 forming a housing and ensuring the disengagement of the roller 12 downwards with locking 18 of the notch taking place on the carrying surface, it being possible for an equivalent result to be obtained by tilting the carrier cradle at the receiver housing. It is intended to ensure that rollers can be removed without dismantling support structures or displacing the transporting belt.

Description

L'obJet de l'invention concerne un dispositif permettant le remplacement rapifle des rouleaux de convoyeurs. The object of the invention relates to a device allowing rapid replacement of the conveyor rollers.

II est destiné à assurer 1 ' amovibilité des rouleaux sans démontage des structures de supports ni déplacement de la bande de transport. It is intended to ensure the removability of the rollers without disassembly of the support structures or displacement of the conveyor belt.

Jusqu ' à ce jour les convoyeurs comportent à la base des trémies, un chassis qui supporte les rouleaux sur lesquels se déplace la bande du transporteur. Ce chassis est formé par une armature fixe sur laquelle sont disposés les logements recevant les arbres fixes, des rouleaux de transport . Ces rouleaux supportent toute la charge que la trémie dirige sur le transporteur. Par ailleurs, le convoyeur se déplace parallèlement au transporteur en soulevant la bande porteuse.De ce fait, ces rouleaux s'usent rapidement et exigent souvent leur changement.Pour les remplacer, il faut alors démonter tout le chassis pour I ' a- baisser de manière à soulever la bande transporteuse et extraire les rouleaux dont les arbres reposent dans les chapes ouvertes vers le haut et formant logements.Cette opération exige un travail très important par un personnel qualifié et immobilise l'exploita- tion pendant des temps très longs. Until now, conveyors have included at the base of the hoppers, a frame which supports the rollers on which the conveyor belt moves. This chassis is formed by a fixed frame on which are arranged the housings receiving the fixed shafts, transport rollers. These rollers support all the load that the hopper directs on the conveyor. In addition, the conveyor moves parallel to the conveyor by lifting the carrying belt. As a result, these rollers wear out quickly and often require their change. To replace them, it is then necessary to dismantle the whole chassis to lower it. so as to lift the conveyor belt and extract the rollers, the shafts of which rest in the open screeds upwards and forming housings. This operation requires very important work by qualified personnel and immobilizes the operation for very long times.

Le dispositif suivant 1 ' invention supprime ces inconvénients et permet d ' assurer le démontage des rouleaux d ' un convoyeur sans démontage du chassis porteur et sans modification de structures porteuses. The device according to the invention eliminates these drawbacks and makes it possible to dismantle the rollers of a conveyor without dismantling the support frame and without modifying the support structures.

II est constitué par I ' inversion d ' une échancrure for- mant logement et assurant le dégagement du rouleau vers le bas avec verrouillage de I ' échancrure pratiquée sur la surface por- teuse; un résultat équivalent pouvant être obtenu par le basculement du berceau porteur au logement récepteur. It is constituted by the inversion of a notch forming a housing and ensuring the disengagement of the roller downwards with locking of the notch practiced on the carrier surface; an equivalent result can be obtained by tilting the carrier cradle to the receiver housing.

Sur les dessins annexés, donnés à titre d ' exemple non limitatif, d'une des formes de réalisation de l'objet de I '
La figure 1 représente un convoyeur avec 50n dispositif porteur de la bande du transporteur.
In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the object of I '
FIG. 1 represents a conveyor with 50n device carrying the conveyor belt.

La figure 2 est une vue en perspective d'une monture porte-rouleau avec chape à échancrure ou logement inversé. Figure 2 is a perspective view of a roller holder frame with scalloped notch or inverted housing.

Les figures 3 et 4 montrent une vue en perspective des variantes d'exécution. Figures 3 and 4 show a perspective view of alternative embodiments.

La trémie 1 (fig 1), du convoyeur débouche sur la bande transporteuse 2, supportée par les rouleaux 3, 4, 5 montés sur un chassis 6 fixé par ses extrémités 7 et 8, sur la monture 9 du convoyeur. The hopper 1 (fig 1) of the conveyor opens onto the conveyor belt 2, supported by the rollers 3, 4, 5 mounted on a frame 6 fixed by its ends 7 and 8, on the frame 9 of the conveyor.

Chaque rouleau tourne sur des axes supportés par des logements formés par des échancrures pratiquées sur les chapes 10, 11. Each roller rotates on axes supported by housings formed by notches made on the yokes 10, 11.

Ces échancrures ne permettent une extraction des rouleaux que si on démonte les assemblages 7, 8 pour abaisser la monture 6. Les arbres et les rouleaux sont alors soulevés et séparés de leurs logements porteurs. These indentations only allow the rollers to be extracted if the assemblies 7, 8 are dismantled to lower the mount 6. The shafts and the rollers are then lifted and separated from their bearing housings.

Le rouleau 12, figure 2 est démontable et peut s'extraire par le bas sans déplacement du tapis 2. The roller 12, Figure 2 is removable and can be extracted from the bottom without moving the carpet 2.

A cet effet, (fig 2) le logement 13 pratiqué sur l'entretoise 15 supportant l'arbre 14 comporte une ouverture 16 orientée vers le haut. To this end, (fig 2) the housing 13 formed on the spacer 15 supporting the shaft 14 has an opening 16 oriented upwards.

Par contre l'entretoise opposée 20 est munie d'une échancrure avec ouverture 19 orientée vers le bas. Une verrou amovible 18 supporte l'arbre 17. En déverrouillant le blocage 18, le rouleau 12 s'extrait par le bas. Against by the opposite spacer 20 is provided with a notch with opening 19 oriented downwards. A removable lock 18 supports the shaft 17. By unlocking the blocking 18, the roller 12 is extracted from below.

Par contre suivant les applications et les appareillages on peut obtenir un résultat équivalent avec des articulations. C'est ainsi que le berceau porteur 21 comportant des logements 22, 23 avec introduction à talonnette est reversible par rotation de 1800 autour des axes 24, 25 (figure 3). On the other hand according to the applications and the apparatuses one can obtain an equivalent result with articulations. Thus the carrier cradle 21 comprising housings 22, 23 with introduction to heel is reversible by rotation of 1800 around the axes 24, 25 (Figure 3).

Les échancrures 22, 23 avec crochets de retenue sont prévues pour empecher le rouleau de tomber lors d'une rotation de 1800.  The notches 22, 23 with retaining hooks are provided to prevent the roll from falling during a rotation of 1800.

On peut également prévoir (figure 4) un basculement du berceau 27, par tourillonnement autour de l'axe 28 afin d'extraire le rouleau 26. It is also possible to provide (FIG. 4) for the cradle 27 to tilt by swiveling around the axis 28 in order to extract the roller 26.

Les rouleaux sont ainsi montés de la façon classique mais sont remplaçables non en les soulevant, mais au contraire en les sortant par le bas sans toucher à la bande transporteuse, ils pourraient également équiper les transporteurs à bande.  The rollers are thus mounted in the conventional way but are replaceable not by lifting them, but on the contrary by taking them out from the bottom without touching the conveyor belt, they could also be fitted to belt conveyors.

Toutefois les formes, dimensions et dispositions des différents éléments, pourront varier dans la limite des équivalents, comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela, la conception générale de l'inven- tion qui vient d'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, like the materials used for their manufacture, without changing the general conception of the invention which has just been described. .
