Abstract

The guide way has a hollow rail (1), inside which rs an endless cable (5). This is held, at each end of the rail, by gullies (6), one of which is driven. The cable is fixed to a trolley (2), supporting the load and rolling inside the rail. The cable has spherical knots (9), spaced regularly on its length and the gullies have recesses to receive them. One cable strand runs in the rail and the other inside a tube (8).

Description

L'invention concerne un chemin de guidage pour le déplacement de charges. The invention relates to a guide path for moving loads.

Lorsqu'il s'agit de déplacer une charge le long d'un chemin complexe présentant des variations de direction plus ou moins brusques et plus ou moins nombreuses, ainsi que des variations de niveau de pentes diverses, on met en oeuvre un rail creux à l'intérieur duquel circule un cible anslfin tendu, aux extrémités du rail, par des poulies dont l'une au moins est motrice. When it comes to moving a load along a complex path with more or less sudden and more or less numerous variations in direction, as well as variations in level of various slopes, a hollow rail is used with inside which circulates an anslfin target stretched, at the ends of the rail, by pulleys of which at least one is driving.

Ce cible est fixé à un chariot qui roule à l'intérieur du rail et qui supporte la charge de façon que par entrarnement du cible on produise le déplacement de la charge suivant le chemin délimité par le rail. This target is fixed to a carriage which rolls inside the rail and which supports the load so that by interlocking with the target the displacement of the load is produced along the path delimited by the rail.

De tels dispositifs sont. par exemple mis en oeuvre pour le déplacement de charges au travers d'ateliers répartis en plusieurs niveaux ou encore pour permettre à des personnes handicapées de se déplacer entre les divers étages de leur habistation, le chariot supportant dans ce cas un siège et circulant à l'intérieur d'un rail disposé à hauteur suffisante au-dessus de l'escalier de l'habitation. Such devices are. for example implemented for the movement of loads through workshops distributed in several levels or to allow disabled people to move between the various floors of their living space, the trolley in this case supporting a seat and circulating in the interior of a rail arranged at a sufficient height above the staircase of the dwelling.

Cependant, la longueur, ainsi que les coudes et changements de niveaux de ces chemins de guidage connus sont limités par le fait que, à chaque changement de direction du rail, le câble frotte sur sa paroi interne, la force de friction étant d'autant plus importante que la charge est élevée. However, the length, as well as the bends and changes in levels of these known guide paths are limited by the fact that, with each change of direction of the rail, the cable rubs on its internal wall, the friction force being all the more more important than the load is high.

Avec ces dispositifs, on est donc contraint d'augmenter la puissance du moteur d'entratnement et de limiter la longueur du rail en fonction du poids de la charge, du nombre de changements de direction du rail et de l'importance de ses changements de niveaux, sans compter qu'il se produit une usure rapide du câble. With these devices, it is therefore necessary to increase the power of the drive motor and to limit the length of the rail as a function of the weight of the load, the number of changes of direction of the rail and the extent of its changes in levels, not to mention rapid cable wear.

La présente invention a notamment pour but de remédier à ces inconvénients et concerne à cet effet un chemin de guidage pour le déplacement de charges se composant d'un rail creux à l'intérieur duquel circule un câble sans fin, tendu, aux extrémités de ce rail, par des poulies dont l'une est motrice, ce câble étant fixé à un chariot supportant la charge et roulant à l'intqrieur du rail, chemin de guidage caractérisé en ce que le câble est pourvu de noyaux régulièrement répartis sur sa longueur, les poulies étant pourvues d'alvéoles aptes à recevoir ces noyaux. The present invention aims in particular to remedy these drawbacks and for this purpose relates to a guide path for the movement of loads consisting of a hollow rail inside which runs an endless cable, stretched, at the ends of this rail, by pulleys, one of which is driving, this cable being fixed to a carriage carrying the load and rolling inside the rail, guide path characterized in that the cable is provided with cores regularly distributed over its length, the pulleys being provided with cells capable of receiving these cores.

Suivant une autre caractéristique de l'invention, les noyaux sont réalisés sous la forme de sphère. According to another characteristic of the invention, the cores are produced in the form of a sphere.

Ltinvention est représentée, à titre d'exemple non limitatif, sur les dessins ci-joints, dans lesquels
- la figure 1 est une vue de dessus schématique d'un chemin de guidage conforme à l'invention
- la figure 2 est une vue latérale partielle du chemin de guidage de la figure 1.The invention is shown, by way of non-limiting example, in the accompanying drawings, in which
- Figure 1 is a schematic top view of a guide path according to the invention
- Figure 2 is a partial side view of the guide path of Figure 1.

La présente invention a notamment pour but la réalisation d'un chemin de guidage qui soit fiable et nécessite une puissance motrice réduite. The object of the present invention is in particular to produce a guide path which is reliable and requires reduced motor power.

Ce chemin se compose d'un rail creux 1 en forme de C dont l'ouverture 11 est dirigée vers le bas, tanais qu'un chariot 2, pourvu de paires de roues 3, roule à l'intérieur de ce rail, les roues 3 prenant appui sur les bords latéraux de l'ouverture longitudinale 11. This path consists of a hollow C-shaped rail 1, the opening 11 of which is directed downward, whereas a carriage 2, provided with pairs of wheels 3, rolls inside this rail, the wheels 3 resting on the lateral edges of the longitudinal opening 11.

A ce chariot est suspendu, de manière articulée, en 21 un moyen d'accrochage 4 de la charge à déplacer, l'arti- culation en 2 de ce moyen permettant à la charge d'être suspendue constamment en position verticale par rapport au chariot, quelles que soient les dénivellations suivies par le rail 1. To this carriage is suspended, in an articulated manner, at 21 a means 4 for attaching the load to be moved, the articulation in 2 of this means allowing the load to be suspended constantly in a vertical position relative to the carriage , whatever the differences in level followed by rail 1.

Le chariot 2 est accroché par ses extrémités avant et arrière à un cible 5 formant une boucle fermée, ce câble étant tendu par deux poulies 6 et 7, disposées à chacune des extrémités du rail 1. The carriage 2 is hooked by its front and rear ends to a target 5 forming a closed loop, this cable being stretched by two pulleys 6 and 7, arranged at each end of the rail 1.

Dans l'exemple représenté sur les dessins, cijoints, l'un des brins du câble tendu entre les poulies 6 et 7 passe au travers du rail 1, tandis que l'autre brin circule à l'intérieur d'un tube Q qui, soit, suit le changement de direction du rail 1, soit, si cela est possible, relie en ligne droite les poulies 6 et 7, comme cela est représenté sur la figure 1.  In the example shown in the attached drawings, one of the strands of the cable stretched between the pulleys 6 and 7 passes through the rail 1, while the other strand flows inside a tube Q which, either follows the change in direction of the rail 1 or, if possible, connects the pulleys 6 and 7 in a straight line, as shown in FIG. 1.

Çonformément à l'invention, des noyaux 9, de préférence réalisés sous la forme de sphère, sont figés de manière régulièrement répartis le long du câble 5, tandis que sur les poulies 6 et 7, sont prévues des alvéoles 10, susceptibles de recevoir les sphères 9 et de garantir ainsi un entraînement sans glissement du câble 5. In accordance with the invention, cores 9, preferably made in the form of a sphere, are fixed in a regular manner distributed along the cable 5, while on the pulleys 6 and 7, are provided cells 10, capable of receiving the spheres 9 and thus guarantee a drive without slipping of the cable 5.

L'écartement des sphères 9 serties et/ou soudées sur le câble 5 sera déterminé de façon à correspondre à la division par un nombre entier de la longueur de la circonférence des poulies 6 et 7, le nombre des alvéoles 10 prévues sur les poulies étant au moins de trois, afin qu'il y ait toujours au moins une sphère logée dans une alvéole. The spacing of the crimped and / or welded spheres 9 on the cable 5 will be determined so as to correspond to the division by an integer of the length of the circumference of the pulleys 6 and 7, the number of cells 10 provided on the pulleys being at least three, so that there is always at least one sphere housed in a cell.

Par la mise en oeuvre de ces sphères, fixées de manière régulièrement réparties le long du câble 1, on obtient une réduction très importante du frottement du câble 5 sur X s parois latérales internes du rail 1 étant donné que ce frottement est limité, pour chaque sphère, théoriquement à un point, le nombre de sphères s'appliquant à frottement sur les parois latérales internes du rail étant fonction du nombre de changements d'orientation 12 du rail et pour chaque changement d'orienstation, de la longueur de la partie coudée de ce rail. By the implementation of these spheres, fixed in a regularly distributed manner along the cable 1, a very significant reduction in the friction of the cable 5 is obtained on X s internal lateral walls of the rail 1 since this friction is limited, for each sphere, theoretically at a point, the number of spheres applying to friction on the internal lateral walls of the rail being a function of the number of changes of orientation 12 of the rail and for each change of orientation, of the length of the bent part of this rail.

La réduction importante de cette force de frottement permettra alors, pour une charge déterminée, de réduire la puissance du moteur entraînant le câble par un réducteur et/ou d'augmenter la longueur du rail 1 sans être limité par le nombre de ces changements de direction.  The significant reduction in this friction force will then, for a determined load, reduce the power of the motor driving the cable by a reducer and / or increase the length of the rail 1 without being limited by the number of these changes of direction. .
