Abstract

The device of the present invention is characterised in that it is essentially composed of a single exhaust duct in the shape of a perforated pipe 1 connected to all the exhausts by means of individual connections 2, and by a caisson 3 housing the exhaust duct 1, equipped with an access cover 4 extending over one of its longitudinal faces, and at its silencer ends 5 each equipped with an oil-retention filter 6.

Description

La présente invention concerne le domaine des machines comportant des distributeurs et/ou des vérins pneumatiques, notamment des machines de scierie, et a pour objet un dispositif de réduction des nuisances de telles machines. The present invention relates to the field of machines comprising distributors and / or pneumatic cylinders, in particular sawmill machines, and relates to a device for reducing the nuisance of such machines.

Actuellement, dans les machines équipées de tels distributeurs etlou vérins, lesdits distributeurs sont généralement montés en échappement libre, ce qui a pour conséquence un niveau de bruit élevé ainsi qu'une pollution relativement importante de l'environnement par un brouillard d'huile. Currently, in machines equipped with such distributors and / or cylinders, said distributors are generally mounted in free exhaust, which results in a high noise level as well as relatively significant pollution of the environment by an oil mist.

Pour réduire les bruits d'échappement, il a été proposé de munir, dans certains cas, chaque distributeur d'un silencieux d'échappement. Un tel dispositif permet une réduction sensible du bruit, mais, cependant, il est nécessaire de prévoir alors, pour un rendement mécanique équivalent, une installation pneumatique de plus grande puissance. En outre, les problèmes de pollution par brouillard d'huile n'ont pas pu être résolus. Enfin, la prévision d'un silencieux sur chaque échappement entraîne souvent des coûts d'installation élevés. To reduce exhaust noise, it has been proposed to provide, in certain cases, each distributor with an exhaust silencer. Such a device allows a significant reduction in noise, but, however, it is necessary then to provide, for equivalent mechanical efficiency, a pneumatic installation of greater power. In addition, the problems of oil mist pollution could not be resolved. Finally, the provision of a silencer on each exhaust often leads to high installation costs.

La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un dispositif de réduction des nuisances, en particulier pour machines comportant un grand nombre de distributeurs et/ou de vérins pneumatiques, notamment de machines de scierie, caractérisé en ce qu'il est essentiellement constitué par un canal d'échappement unique sous forme d'un tuyau perforé relié à tous les échappements au moyen de raccords individuels, et par un caisson logeant le canal d'échappement, muni d'un couvercle d'accès s'étendant sur une de ses faces longitudinales, et à ses extrémités de silencieux pourvus chacun d'un filtre de retenue d'huile. It relates, in fact, to a device for reducing nuisance, in particular for machines comprising a large number of distributors and / or pneumatic cylinders, in particular sawmill machines, characterized in that it is essentially constituted by a channel single exhaust in the form of a perforated pipe connected to all the exhausts by means of individual fittings, and by a box housing the exhaust channel, provided with an access cover extending on one of its longitudinal faces , and at its ends of the silencer each provided with an oil retaining filter.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel la figure 1 est une vue en élévation par l'arrière d'un dispositif conforme à l'invention, et la figure 2 est une vue en plan suivant la figure 1. The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, in which FIG. 1 is a view in rear elevation of a device according to the invention, and FIG. 2 is a plan view according to FIG. 1.

Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 et 2 du dessin annexé, le dispositif de réduction des nuisances, en particulier pour machines comportant un grand nombre de distributeurs et/ou-de vérins pneumatiques, notamment de machines de scierie, est essentiellement constitué par un canal d'échappement en forme de tuyau perforé 1, qui est relié aux échappements des divers distributeurs et/ou vérins (non représentés) au moyen de raccords individuels 2. Le tuyau perforé 1 est logé dans un caisson 3, qui est muni d'un couvercle 4. Ce dernier permet un accès aisé à l'intérieur du caisson 3 et s'étend sur une face longitudinale dudit caisson 3, de préférence sur sa face arrière. In accordance with the invention, and as shown more particularly, by way of example, FIGS. 1 and 2 of the appended drawing, the device for reducing nuisances, in particular for machines comprising a large number of distributors and / or pneumatic cylinders, in particular for sawmill machines, essentially consists of an exhaust channel in the form of a perforated pipe 1, which is connected to the exhausts of the various distributors and / or cylinders (not shown) by means of individual fittings 2. The pipe perforated 1 is housed in a box 3, which is provided with a cover 4. The latter allows easy access to the inside of the box 3 and extends over a longitudinal face of said box 3, preferably on its rear face.

En vue d'améliorer davantage l'effet de réduction du bruit, il est prévu, aux extrémités du caisson 3, des silencieux 5, reliant l'intérieur dudit caisson 3 à l'atmosphère, et pourvus chacun d'un filtre 6 de retenue d'huile. In order to further improve the noise reduction effect, mufflers 5 are provided at the ends of the box 3, connecting the interior of said box 3 to the atmosphere, and each provided with a retaining filter 6 oil.

Le canal d'échappement sous forme de tuyau perforé 1 permet l'obtention d'un effet de "pot d'échappement", c'est-à-dire qu'il permet de réduire le bruit d'échappement sans entraîner de perte de charge. En outre, ce tuyau 1 sert également comme premier collecteur pour l'huile s'échappant habituellement en brouillard au niveau de chaque échappement de distributeur et/ou de vérin, le brouillard d'huile résiduel étant dispersé à l'intérieur du caisson 3 où il se condense en plus grande partie. Les filtres 6 prévus sur les silencieux 5 des extrémités du caisson 3 permettent une retenue de l'huile résiduelle en suspension, de sorte qu' aucune pollution de l'atmosphère environnant n'est plus possible, tandis que les silencieux 5, qui présentent avantageusement des orifices de grande dimension, assurent une réduction supplémentaire du bruit d'échappement. The exhaust channel in the form of a perforated pipe 1 makes it possible to obtain an "exhaust" effect, that is to say that it makes it possible to reduce the exhaust noise without causing loss of charge. In addition, this pipe 1 also serves as the first collector for the oil usually escaping in mist at each distributor and / or cylinder exhaust, the residual oil mist being dispersed inside the box 3 where most of it condenses. The filters 6 provided on the silencers 5 at the ends of the box 3 allow retention of the residual oil in suspension, so that no pollution of the surrounding atmosphere is no longer possible, while the silencers 5, which advantageously have large holes provide additional reduction in exhaust noise.

Selon une autre caractéristique de l'invention, le canal 3 peut avantageusement être garni intérieurement d'un revêtement 7 sous forme d'une isolation sonore, ce revêtement étant également prévu sur le couvercle 4. According to another characteristic of the invention, the channel 3 can advantageously be lined internally with a covering 7 in the form of sound insulation, this covering also being provided on the cover 4.

Le canal 3 est agencé de manière à loger toutes les conduites pneumatiques, notamment la conduite de pression principale 8, et les raccords 9 pour les conduites secon- daires 10 ainsi que les câbles de branchement électrique (non représentés), des joints de passage 11 pour les branchements individuels étant prévus sur au moins une face longitudinale du caisson 3. Ainsi, la sécurité de la machine à commander est améliorée, le caisson 3 assurant un rôle de chemin de câbles ou de conduites de branchement, alors que dans les machines connues tous ces organes sont branchés librement sans protection. The channel 3 is arranged so as to accommodate all the pneumatic lines, in particular the main pressure line 8, and the connections 9 for the secondary lines 10 as well as the electrical connection cables (not shown), passage joints 11 for the individual connections being provided on at least one longitudinal face of the box 3. Thus, the safety of the machine to be controlled is improved, the box 3 fulfilling a role of cable tray or connection pipes, whereas in known machines all these components are freely connected without protection.

Enfin, selon une autre caractéristique de l'invention, non représentée au dessin annexé, la partie inférieure du caisson 3 est avantageusement réalisée en forme de bac de récupération de l'huile d'échappement en suspension et est muni d'un orifice de soutirage permettant le retraitement éventuel de ladite huile. Finally, according to another characteristic of the invention, not shown in the accompanying drawing, the lower part of the box 3 is advantageously made in the form of a recovery tank for the exhaust oil in suspension and is provided with a withdrawal orifice. allowing the possible reprocessing of said oil.

Grâce à l'invention, il est possible de réaliser un dispositif permettant, à un moindre coût, des réductions très importantes des nuisances engendrées par les distributeurs et les vérins pneumatiques de machines, et pouvant être mis en oeuvre d'une manière très simple. Thanks to the invention, it is possible to produce a device allowing, at a lower cost, very significant reductions in the nuisance caused by the distributors and the pneumatic cylinders of machines, and which can be implemented in a very simple manner.

L'invention est plus particulièrement applicable dans le domaine des dispositifs de commande de machines de scierie, mais son application est également très intéressante dans le domaine de l'industrie alimentaire, ôù un grand nombre de manutentions est réalisé pneumatiquement.  The invention is more particularly applicable in the field of sawmill machine control devices, but its application is also very advantageous in the field of the food industry, where a large number of handling operations is carried out pneumatically.

Bien entendu invention n"est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing.

Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments' ou par substitution d ' équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
