Abstract
Description
La présente invention a pour objet un système modulaire de distribution d'un fluide sous pression pour la commande de plusieurs dispositifs moteurs tels que par exemple des moteurs ou vérins pneumatiques ou des vannes.The present invention relates to a modular system for distributing a pressurized fluid for the control of several motor devices such as for example pneumatic motors or cylinders or valves.
Dans des systèmes connus, un distributeur de fluide sous pression est associé à chaque dispositif moteur, par l'intermédiaire d'une plaque d'embase. Cette dernière comprend une face avant et une face arrière de raccordement comportant des orifices d'entrée et de sortie de fluide sous pression et des orifices d'échappement et, sur une autre face, des orifices de sortie reliés au dispositif moteur et des orifices de pilotage ou de commande ainsi qu'une face de pose d'interchangeabilité du distributeur associé comportant des orifices de raccordement au distributeur, qui sont en communication avec les orifices des faces avant et arrière et les orifices de sortie ou d'utilisation et de commande de la plaque d'embase.In known systems, a pressurized fluid distributor is associated with each motor device, via a base plate. The latter comprises a front face and a rear connection face comprising inlet and outlet openings for pressurized fluid and outlet openings and, on another face, outlet openings connected to the engine device and outlet openings piloting or control as well as an interchangeability installation face of the associated distributor comprising orifices for connection to the distributor, which are in communication with the orifices of the front and rear faces and the outlet or use and control orifices for the base plate.
Ces systèmes distributeurs comprennent souvent au moins deux groupes de distributeurs de taille différente pour assurer l'alimentation en fluide sous pression de dispositifs moteurs, notamment de vérins pneumatiques, exigeant respectivement un débit de fluide relativement élevé ou relativement faible. Un premier groupe très majoritaire et d'une taille comparativement petite est conçu pour un débit relativement faible, pour alimenter par exemple des vérins ne demandant pas des efforts trop élevés. Il s'agit des vérins de petit alésage et/ou de vitesse pas trop élevée. Le distributeur du deuxième groupe généralement plus restreint en nombre d'éléments et en nombre d'unités est dimensionné pour pouvoir fournir un débit plus élevé à des vérins se déplaçant à des vitesses plus élevées et dont les alésages sont par conséquent plus importants. Ces distributeurs ont une taille qui est plus grande que celle des distributeurs du premier groupe ou type. A chaque type de distributeur, spécifique par sa taille, correspond un type d'embase qui se distingue également par sa taille des embases de l'autre type ou groupe de distributeur.These dispensing systems often include at least two groups of dispensers of different sizes to ensure the supply of pressurized fluid to motor devices, in particular pneumatic cylinders, respectively requiring a relatively high or relatively low fluid flow rate. A first very large group and a comparatively small size is designed for a relatively low flow, to supply for example jacks that do not require too high forces. These are small bore and / or not too high speed cylinders. The distributor of the second group, generally more limited in number of elements and in number of units, is dimensioned so as to be able to provide a higher flow rate to cylinders moving at higher speeds and whose bores are therefore greater. These distributors have a size which is larger than that of the distributors of the first group or type. Each type of distributor, specific by its size, corresponds to a type of base which is also distinguished by its size from the bases of the other type or group of distributor.
Dans les systèmes distributeurs connus les embases du même type de taille sont associables entre elles par raccordement direct, en série, par leurs faces de raccordement correspondantes. Par contre en raison de leur taille différente et de la différence de leur plan de raccordement, qui en résulte, une telle association directe de deux embases de taille différente est exclue. Dans les systèmes connus, les interconnexions entre les embases de taille différente sont réalisées par câblage.In known distributor systems, the bases of the same type of size can be joined together by direct connection, in series, by their corresponding connection faces. By cons because of their different size and the difference in their connection plan, which results, such a direct association of two bases of different size is excluded. In known systems, the interconnections between the bases of different sizes are made by wiring.
Cette interconnexion par câblage des embases de type différent constitue un inconvénient considérable lors de la réalisation d'un système modulaire de distribution de fluide sous pression et rend ces systèmes très encombrants et peu compacts.This interconnection by wiring of the bases of different type constitutes a considerable drawback when producing a modular system for distributing fluid under pressure and makes these systems very bulky and not very compact.
L'invention a pour objectif de pallier ces inconvénients. Pour atteindre ce but, deux plaques d'embase dont les configurations des orifices dans les faces de raccordement sont différentes, sont associées par l'intermédiaire d'une plaque de transfert comprenant des faces de raccordement aux embases, dont les configurations des orifices de raccordement sont différentes et correspondent à celles des deux plaques d'embase.The invention aims to overcome these drawbacks. To achieve this goal, two base plates whose configurations of the orifices in the connection faces are different, are associated by means of a transfer plate comprising connection faces to the bases, whose configurations of the connection orifices are different and correspond to those of the two base plates.
Selon une caractéristique avantageuse de l'invention, les unités distributeurs-embases de type différentes sont assemblées de façon à former un seul bloc rigide et compact.According to an advantageous characteristic of the invention, the distributor-base units of different types are assembled so as to form a single rigid and compact block.
L'invention sera mieux comprise et d'autres buts, caractéristiques détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant deux modes de réalisation de l'invention, et dans lesquels .The invention will be better understood and other aims, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating two modes of realization of the invention, and in which.
- La figure 1 illustre de façon schématique, l'association selon l'invention de deux types de plaques d'embase de taille différente.Figure 1 illustrates schematically, the association according to the invention of two types of base plates of different sizes.
- La figure 2 est une vue de dessus sur un assemblage selon l'invention de deux groupes d'unités distributeur-embase.Figure 2 is a top view on an assembly according to the invention of two groups of distributor-base units.
- Les figures 3 à 5 sont des vues respectivement de dessus et latérales d'une plaque de transfert selon l'invention.Figures 3 to 5 are respectively top and side views of a transfer plate according to the invention.
- La figure 6 montre une variante d'une plaque de transfert selon l'invention, destinée à l'assemblage de deux types d'embase de longueur différente.FIG. 6 shows a variant of a transfer plate according to the invention, intended for the assembly of two types of base of different length.
La figure 1 représente de façon schématique un système modulaire de distribution d'un fluide sous pression, qui comprend une première unité de distribution U1 comportant un distributeur D1 et sa plaque d'embase associée E1 et un groupe de deux unités de distribution U2 comportant chacune un distributeur D2 monté sur sa plaque d'embase E2. L'embase E1 et la première embase E2 sont reliées rigidement par une plaque de transfert P selon l'invention. Les deux embases E2 sont directement associées l'une à l'autre. L'unité de distribution U1 est conçue pour alimenter un dispositif moteur à un débit relativement élevé tandis que les deux unités E2 sont destinées à l'alimentation de dispositifs moteurs ne nécessitant qu'un débit de fluide sous pression relativement faible. La taille de l'unité U1 est par conséquent plus grande que la taille des unités U2.FIG. 1 schematically represents a modular distribution system for a pressurized fluid, which comprises a first distribution unit U 1 comprising a distributor D 1 and its associated base plate E 1 and a group of two distribution units U 2 each comprising a distributor D 2 mounted on its base plate E 2 . The base E 1 and the first base E 2 are rigidly connected by a transfer plate P according to the invention. The two E 2 bases are directly associated with each other. The distribution unit U 1 is designed to supply a motor device at a relatively high flow rate while the two units E 2 are intended for supplying motor devices requiring only a flow of fluid under relatively low pressure. The size of the unit U 1 is therefore larger than the size of the units U 2 .
La configuration des distributeurs et des plaques d'embase ainsi que la réalisation des faces d'accrochage mutuel et des faces de pose des embases sont connues en soi et ne sont décrites par la suite que pour faciliter la compréhension de l'invention.The configuration of the distributors and of the base plates as well as the production of the mutual attachment faces and of the mounting faces of the bases are known per se and are described below only to facilitate understanding of the invention.
Les distributeurs D1 et D2 représentés sur la figure 1, sont du même type, c'est-à-dire du type 5/2 comprenant un orifice d'alimentation en fluide sous pression 1, deux orifices d'utilisation ou de sortie 2, 4, deux orifices d'échappement 3, 5 et deux orifices de commande 12, 14. Ces orifices se trouvent dans un même plan du distributeur.The distributors D 1 and D 2 shown in FIG. 1 are of the same type, that is to say of the 5/2 type comprising a pressure
Chaque distributeur D est monté de façon amovible et interchangeable sur la surface supérieure 20 d'une plaque d'embase E1, E2. Cette surface 20 est conformée en plan de pose d'interchangeabilité et présente à cette fin la configuration d'orifices de raccordement au distributeur, représentée sur la figure 2. Les orifices du plan de pose des embases sont désignés par les mêmes chiffres de référence que les orifices du distributeur auquel ils doivent être raccordés. Les orifices de pression 1 et d'échappement 3, 5 du plan de pose communiquent respectivement avec des canaux internes 21, 22, 23 qui traversent entièrement la plaque d'embase et débouchent sur les faces de raccordement avant et arrière 24, 25 de l'embase. Le canal 21 constitue le canal d'alimentation en fluide sous pression, tandis que les canaux 22 et 23 servent de canaux d'échappement. Les orifices d'entrée et de sortie du canal de pression 21 portent respectivement les chiffres de référence 26 et 27. Les orifices d'entrée et de sortie des canaux d'échappement sont désignés sur les figures respectivement par 28 et 29. Les orifices d'utilisation 2, 4 et les orifices de commande 12 14 du plan de pose 20 de l'embase sont en communication avec des orifices dans une autre face de la plaque d'embase comme cela est illustré de façon schématique sur la figure 1, pour pouvoir être relié au dispositif moteur et au dispositif de commande.Each distributor D is removably and interchangeably mounted on the
Toutes les plaques d'embase d'un type, c'est-à-dire du type E1 ou E2 sont identiques et conçus pour permettre une association en série de plusieurs plaques d'embase, par raccordement direct d'une face arrière 25 d'une embase à la face avant 24 d'une autre embase. Par contre il est impossible de raccorder de cette même manière une plaque d'embase E1 à une plaque d'embase E28 En effet, comme il ressort de la figure 2, l'écart entre les orifices 28, 29 dans la face de raccordement arrière 25 de la plaque d'embase E1 et le cas échéant le diamètre de ces orifices sont supérieurs aux écartements et aux diamètres que présentent les orifices 26, 27 de la face de raccordement avant 24 de la plaque d'embase E2.All base plates of one type, i.e. type E 1 or E 2, are identical and designed to allow a series association of several base plates, by direct connection of a rear face. 25 from a base to the
Pour qu'il soit quand même possible de relier rigidement les deux plaques d'embase E1, E2 qui sont de type différent , on interpose, selon l'invention, la plaque de transfert P entre ces deux plaques d'embase. Cette plaque sera décrite en se reportant aux figures 2 à 5 représentant un premier mode de réalisation d'une telle plaque. On constate que les plaques d'embase E1 et E2 et la plaque de transfert ont la même longueur L. La plaque de transfert P présente dans sa face de raccordement avant 31 une configuration d'orifices 32, 33 qui est identique à celle des orifices 27, 29 de la face arrière 25 de la plaque d'embase E1, tandis que le dispositif des orifices 34, 35 pratiqué dans la face de raccordement arrière 36 de la plaque de transfert correspond à celui des orifices 26, 28 de la face avant 24 de la plaque d'embase E2. Les orifices 32 et 34 sont reliés par un canal rectiligne 37 qui s'étend parallèlement à l'axe de l'assemblage en série des embases. Par contre, les canaux de liaison 38 des orifices d'échappement 33 et 35 sont coudés pour compenser la différence d'écartement de l'axe du canal 37, des orifices 33 et 35.So that it is still possible to rigidly connect the two base plates E 1 , E 2 which are of different type, the plate is interposed according to the invention transfer P between these two base plates. This plate will be described with reference to Figures 2 to 5 showing a first embodiment of such a plate. It can be seen that the base plates E 1 and E 2 and the transfer plate have the same length L. The transfer plate P has in its front connection face 31 a configuration of
Dans le mode de réalisation de l'invention représenté à la figure 6 la plaque de transfert P est conformée pour raccorder deux types de plaques d'embase E3, E4 dont la longueur est différente. Dans ce cas, la plaque d'embase P doit compenser une plus grande différence d'écart de la ligne médiane des orifices pratiqués dans les faces de raccordement avant et arrière 24, 25 de plaques:d'embase. Ceci est illustré schématiquement par une inclinaison relativement importante par rapport à l'axe, des canaux d'échappement 37.In the embodiment of the invention shown in Figure 6 the transfer plate P is shaped to connect two types of base plates E 3 , E4 whose length is different. In this case, the base plate P must compensate for a greater difference in deviation from the center line of the orifices made in the front and rear connection faces 24, 25 of the base plates. This is illustrated schematically by a relatively large inclination relative to the axis, of the
On comprend aisément que le système de distribution selon l'invention, notamment grâce à l'utilisation de la plaque de transfert, permet de créer un seul bloc de distributeurs en supprimant les câblages. On obtient un gain des raccords et du temps de câblage et on constate que l'encombrement de l'installation est fortement réduit grâce aux mesures spécifiques à l'invention.It is easily understood that the distribution system according to the invention, in particular through the use of the transfer plate, makes it possible to create a single block of distributors by eliminating the wiring. We get a gain in connections and wiring time and we see that the size of the installation is greatly reduced thanks to the measures specific to the invention.
Bien entendu, de diverses modifications peuvent être apportées au principe de l'invention qui vient d'être décrit et qui est représenté sur les figures. Ainsi la configuration de la plaque de transfert et des canaux qui la traversent peut être différente sans que cela entraîne un changement au niveau du principe de l'invention.Of course, various modifications can be made to the principle of the invention which has just been described and which is shown in the figures. Thus the configuration of the transfer plate and the channels which pass through it can be different without this resulting in a change in the principle of the invention.
