Abstract
Description
Les convoyeurs destinés à véhiculer des charges sur un plan horizontal, tels que les transporteurs à écailles, comprennent généralement deux chaines motrices munies de taquets éclipsables qui viennent coopérer avec la channe en vue de la déplacer. L'ensemble de commande pourvu des deux chaînes motrices est orienté verticalement de manière que ses taquets viennent attaquer la chaîne du convoyeur en dessous de celle-ci. Conveyors intended to transport loads on a horizontal plane, such as flake conveyors, generally include two drive chains provided with eclipsable cleats which come to cooperate with the chain in order to move it. The control assembly provided with the two drive chains is oriented vertically so that its catches come to attack the conveyor chain below it.
Un tel agencement est complexe et lourd, de telle sorte que son prix de revient est élevé. On ne peut donc pas envisager l'utilisation d'un tel appareillage pour la mise en oeuvre d'un convoyeur léger. Such an arrangement is complex and cumbersome, so that its cost price is high. One cannot therefore envisage the use of such an apparatus for the implementation of a light conveyor.
Les perfectionnements qui font 11 objet de la présente invention visent à permettre la réalisation d'un convoyeur dont la chaîne de transport soit susceptible d'être entraînée par des taquets solidaire d'une chaîne motrice ou chenille se déplaçant dans un plan horizontal. The improvements which are the subject of the present invention aim to allow the production of a conveyor, the transport chain of which is capable of being driven by cleats secured to a drive chain or track moving in a horizontal plane.
Ainsi, les taquets peuvent-ils attaquer des doigts de la chaîne porteuse situés entre les articulations des maillons, lesdites articulations étant pourvues de galets de roulement et de direction.Thus, the cleats can they attack fingers of the carrying chain located between the articulations of the links, said articulations being provided with rollers and with steering.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une coupe transversale d'un convoyeur comportant application des perfectionnements suivant l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a cross section of a conveyor comprising application of the improvements according to the invention.
Fig. 2 en est une vue partielle par-dessus montrant-de quelle manière la chaîne porteuse est entraînée. Fig. 2 is a partial view from above showing how the carrier chain is driven.
Le transporteur illustré en fig. 1 comprend un châssis 1 pourvu de pieds 2 et de traverses 3 qui supportent un chemin de roulement 4 d'une chaîne transporteuse 5 à laquelle sont associées des écailles 6, conte cela est bien connu dans la pratique, par exemple pour réaliser des transporteurs de bagages dans les aéroports. The transporter illustrated in fig. 1 comprises a frame 1 provided with feet 2 and crosspieces 3 which support a raceway 4 of a conveyor chain 5 with which scales 6 are associated, as is well known in practice, for example for making transporters of baggage at airports.
Le chemin de roulement 4 est constitué par un longeron 7 qui soutient un profilé 8 affectant la forme générale d'un U et réalisé en une matiere plastique. Le profilé 8 comprend une gorge centrale 8a et deux rebords supérieurs 8h, 8c. The raceway 4 is constituted by a spar 7 which supports a profile 8 affecting the general shape of a U and made of a plastic. The profile 8 comprises a central groove 8a and two upper edges 8h, 8c.
Chaque articulation de~la chaîne 5 est pourvue d'un cavalier 9 dont les ailes portent chacune un axe 9a, 9bsur lequel tourillonne un galet 10, 11 reposant sur les rebords 8b, 8c du profilé 8, et un axe vertical 9c dont l'extrémité inférieure dépasse en dessous de la chaîne 5 pour porter un galet 12 qui coopère avec les deux parois verticales de la gorge 8a du profilé 8. Le support d'écaille 6a qui porte l'écaille 6 est fixé sur les maillons de la chaîne 5, les bords glissent sur des guides la, lb du châssis 1 par l'intermédiaire de patins 6b, 6c. Each articulation of ~ the chain 5 is provided with a jumper 9 whose wings each carry an axis 9a, 9bsur which journals a roller 10, 11 resting on the edges 8b, 8c of the profile 8, and a vertical axis 9c whose lower end protrudes below the chain 5 to carry a roller 12 which cooperates with the two vertical walls of the groove 8a of the profile 8. The scale support 6a which carries the scale 6 is fixed on the links of the chain 5 , the edges slide on guides 1a, 1b of the chassis 1 by means of pads 6b, 6c.
En fig. 2 on n'a pas représenté l'écaille 6 de manière à ne pas surcharger le dessin. In fig. 2 the scale 6 has not been shown so as not to overload the drawing.
On observe au niveau de chaque maillon la présence d'un doigt vertical 14 contre lequel viennent prendre appui des taquets successifs 15 d'une chaîne d'entrarnement 16 passant-autour de deux roues 17, 18 dont la première est motrice. L'ensemble ainsi constitué forme ce qu'on appelle dans la pratique une chenille ou caterpilar . On observe que les axes des deux roues 17, 18 sont verticaux de telle sorte que les taquets 15 se trouvent à l'horizontale. Lorsque la roue 17 est entraînée, les taquets viennent se placer entre les joues de chaque maillon successif de manière à prendre appui sur les doigts 14 en vue de provoquer la translation de la chaîne 5. On observe que chaque taquet est pourvu de deux roulettes 19, 20 qui viennent rouler sur une rampe verticale fixe 21 au niveau de l'entraînement de la chaîne 5. Ainsi, on est assuré que la tête des taquets référencée 15a viendra bien en appui contre les doigts 14. Comme illustré en fig. 1, la rampe 21 est soutenue par un montant 22 faisant partie du châssis 1. On choisit avantageusement de revêtir la face active de la rampe 21 d'une bande de matière plastique contre laquelle les roulettes 19 et 20 prennent appui. On améliore ainsi le roulement tout en diminuant le bruit engendré par ce dernier. We observe at each link the presence of a vertical finger 14 against which come to bear successive cleats 15 of a drive chain 16 passing around two wheels 17, 18 of which the first is driving. The assembly thus formed forms what is in practice called a caterpillar or caterpilar. It is observed that the axes of the two wheels 17, 18 are vertical so that the cleats 15 are horizontal. When the wheel 17 is driven, the tabs are placed between the cheeks of each successive link so as to bear on the fingers 14 in order to cause the translation of the chain 5. It is observed that each cleat is provided with two rollers 19 , 20 which come to roll on a fixed vertical ramp 21 at the drive of the chain 5. Thus, it is ensured that the head of the tabs referenced 15a will come into abutment against the fingers 14. As illustrated in fig. 1, the ramp 21 is supported by an upright 22 forming part of the chassis 1. It is advantageously chosen to coat the active face of the ramp 21 with a strip of plastic material against which the rollers 19 and 20 bear. This improves the rolling while reducing the noise generated by it.
On a ainsi réalisé un convoyeur pour charge légère qui est de construction simple de telle sorte que son prix est très bas. A light load conveyor has thus been produced which is simple in construction so that its price is very low.
I1 doit d'ailleurs être entendu que la description qui précède n'aété donnée qulà titre d'exemple et qu'elle ne limite nullement le domaine ne l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalent.
