Abstract

Rectangular machines components are washed and dried by a machine with two disc-shaped rotors (2,3) spaced apart on a horizontal driving shaft. Each rotor has rectangular openings (5) around its periphery, to receive the components (4), one rotor (2) being partly immersed in a liquid bath (14) containing a rotary head (8) to a system of drying air jets. The nozzles have horizontal supply tubes with inwardly bent ends guiding water at high pressure or air towards the sides of the components. The nozzles can then be rotated round each component while stationary so that the component is treated all round. Both rotors can be partly immersed in vessels so that either can be used for different treatments.

Sont déjà connus différents types de machines de ce genre telle celle décrite dans le brevet européen no 0.005.069, accordé au nom de la société pétitionnaire elle-même. Ce type de machine concerne celles utilisées pour le traitement de pièces usinées par procédé de lava­ge, jet, ébarbage et/ou séchage.Are already known different types of machines such as that described in European Patent No. 0,005,069, granted on behalf of the petitioner company itself. This type of machine concerns those used for the treatment of machined parts by washing, jet, deburring and / or drying process.

Dans les machines qui appliquent ce type de trai­tement, les jets de fluide de traitement sont toujours fixes et il faut faire tourner la pièce face à ces jets pendant la phase opératoire afin que le fluide atteigne facilement la surface totale de la pièce à traiter, no­tamment en ce qui concerne ses trous, cavités et recoins d'accès difficile.In machines which apply this type of treatment, the jets of treatment fluid are always fixed and the part must be turned opposite these jets during the operating phase so that the fluid easily reaches the total surface of the part to be treated, in particular as regards its holes, cavities and recesses of difficult access.

Toutefois, ces machines ont besoin de mécanismes hautement compliqués pour faire en sorte que les pièces, dont le poids est relativement élevé, puissent tourner dans les stations opératoires disposées sur une roue por­teuse de pièces.However, these machines need highly complicated mechanisms to ensure that the relatively heavy parts can rotate in operating stations located on a workpiece-carrying wheel.

Afin d'éviter cet important ennui et d'utiliser au maximum les performances de ce type de machine, a été prévue celle faisant l'objet de la présente invention qui, dans sa nature, est caractérisée par le fait que chacune des boîtes de lavage ou de séchage comprend un ensemble de bras orientés parallèlement en porte-à-faux et au sens sensiblement horizontal, munis d'au moins une buse de sortie de fluide laveur ou sécheur, ces bras étant supportés par un collecteur horizontal commun, pi­votant autour de son axe longitudinal et placé face à une position statique de travail d'une roue porteuse de piè­ces, ces bras étant disposés aussi de sorte que dans cha­que staton de travail la pièce est logée entre eux, ceux-ci l'entourant par la rotation du collecteur commun, pendant la phase opératoire, dans cette staton de tra­vail.In order to avoid this major annoyance and to make maximum use of the performance of this type of machine, provision has been made for the object of the present invention which, in its nature, is characterized by the fact that each of the washing boxes or drying comprises a set of arms oriented in parallel overhang and in the substantially horizontal direction, provided with at least one washer or dryer fluid outlet nozzle, these arms being supported by a common horizontal collector, pivoting around its longitudinal axis and placed facing a static working position of a wheel carrying parts, these arms also being arranged so that in each working staton the part is housed therebetween, these surrounding it by the rotation of the common collector, during the operating phase, in this working staton.

Selon une autre caractéristique de l'invention, les pièces sont supportées par chaque roue dépassant en porte-à-faux le plan de la roue.According to another characteristic of the invention, the parts are supported by each wheel projecting beyond the plane of the wheel.

Conformément à une autre caractéristique de l'in­vention, l'arbre de rotaton de chaque collecteur commun est monté de sorte qu'il peut se déplacer par rotation autour d'un axe aligné avec celui de la ou des roues por­teuses de pièces afin de faciliter les tâches d'entretien de la machine.According to another characteristic of the invention, the rotaton shaft of each common collector is mounted so that it can move by rotation around an axis aligned with that of the part-carrying wheel or wheels in order to facilitate machine maintenance tasks.

Selon une autre caractéristique de l'invention, chaque collecteur commun creux est monté rotativement à l'intérieur d'un support fixé à l'extrémité d'une condui­te d'alimentation de fluide laveur ou sécheur, ce collec­teur recevant le fluide à travers des ouvertures prati­quées dans sa paroi.According to another characteristic of the invention, each common hollow manifold is rotatably mounted inside a support fixed to the end of a supply line for washer or dryer fluid, this manifold receiving the fluid through openings in its wall.

Finalement, conformément à une autre caractéris­tique de l'invention, la machine comprend avantageusement des buses aspergeuses de liquide laveur fixées face aux positions de lavage des pièces, sur le côté de la pièce opposé à celui où se trouve le collecteur commun corres­pondant d'une boîte de lavage à buses tournantes.Finally, in accordance with another characteristic of the invention, the machine advantageously comprises spraying nozzles for washing liquid fixed opposite the parts washing positions, on the side of the part opposite to that where the corresponding common collector is located. washing box with rotating nozzles.

Les dessins ci-joints illustrent, à titre d'exem­ple non limitatif, un mode de réalisation de la machine fasant l'objet de la présente invention.

  • La Fig. 1 est une vue schématique de la machine dont il s'agit lors d'une application avec une première roue porteuse de pièces destinées à être lavées par cavi­tation au moyen de jets submergés, et une deuxième roue porteuse de pièces destinées au séchage;
  • la Fig. 2 est une vue schématique en élévation latérale de la machine de la Fig. 1; et
  • les Fig. 3 et 4 sont aussi des vues schématiques, en élévation de face et en élévation latérale, respecti­vement, de la partie de la machine correspondant à la zo­ne de lavage des pièces.
The attached drawings illustrate, by way of nonlimiting example, an embodiment of the machine making the object of the present invention.
  • Fig. 1 is a schematic view of the machine in question during an application with a first wheel carrying parts intended to be washed by cavitation by means of submerged jets, and a second wheel carrying parts intended for drying;
  • Fig. 2 is a schematic side elevation view of the machine of FIG. 1; and
  • Figs. 3 and 4 are also schematic views, in front elevation and in lateral elevation, respectively, of the part of the machine corresponding to the parts washing zone.

Dans ces dessins l'on peut apprécier que la ma­chine dont il s'agit comprend un dispositif de transfert 1, du type de ceux dits de pas de "pèlerin", qui convoie les pièces qu doivent être lavées et séchées, une pre­mière roue 2 porteuse de pièces 4 pour être lavées et une deuxième roue 3 porteuse de pièces 4 pour être séchées.In these drawings it can be appreciated that the machine in question comprises a transfer device 1, of the type of those known as "pilgrim" steps, which conveys the parts to be washed and dried, a first wheel 2 parts carrier 4 to be washed and a second wheel 3 parts carrier 4 to be dried.

Ces roues 2 et 3 sont munies de logements indivi­duels 5 équipés d'organes presseurs périphériques 6 qui, pas à pas, vont en s'arrêtant aux différentes stations de lavage ou séchage par lesquelles passe successivement chaque pièce 4.These wheels 2 and 3 are provided with individual housings 5 equipped with peripheral pressing members 6 which, step by step, stop at the various washing or drying stations through which each part 4 passes successively.

Dans chaque roue 2, 3 une station 7 de chargement et déchargement est prévue où l'organe presseur 6 corres­pondant lâche sur le dispositif de transfert 1 une pièce 4 lavée ou séchée qu se trouve dans la roue en prenant ensuite une autre pièce pour la laver ou la sécher.In each wheel 2, 3 a loading and unloading station 7 is provided where the corresponding pressing member 6 loosens on the transfer device 1 a washed or dried part 4 which is in the wheel, then taking another part to wash it or dry it.

Dans la réalisation représentée dans les dessins, la partie inférieure de la roue 2 porteuse de pièces 4 au lavage est submergée dans un bain 14 contenu dans une cu­ve 16 dont le niveau supérieur du liquide laveur 17 est inférieur à l'axe 11 commun aux deux roues 2 et 3.In the embodiment shown in the drawings, the lower part of the wheel 2 carrying parts 4 for washing is submerged in a bath 14 contained in a tank 16 whose upper level of the washing liquid 17 is less than the axis 11 common to both wheels 2 and 3.

Le liquide de lavage du bain 14 est pompé par la pompe 18 qui le transvase par le filtre 19 aux bras 15 par les conduites 20 respectives qui sont solidairement reliées aux supports 21 correspondants, à l'intérieur desquels tourne un collecteur commun 22 muni des bras 15, chacun desquels est équipé en extrémité d'une buse asper­geuse 10.The bath washing liquid 14 is pumped by the pump 18 which transfers it through the filter 19 to the arms 15 by the respective conduits 20 which are integrally connected to the corresponding supports 21, inside which a common collector 22 provided with the arms rotates. 15, each of which is fitted at the end with a spray nozzle 10.

Chaque collecteur commun 22 est équipé des ouver­tures 23 par lesquelles pénètre le liquide en provenance de la conduite 20, qui arrive par conséquent aux bras 15.Each common manifold 22 is equipped with openings 23 through which the liquid coming from the pipe 20 penetrates, which consequently arrives at the arms 15.

La rotation de chaque collecteur 22 est faite au moyen d'une roue dentée 24 solidaire du collecteur, qui est entraînée par un pignon 25 entraîné à son tour par un motoréducteur 26. Ce motoréducteur entraîne toutes les unités ou collecteurs 22 existant dans la machine.Each collector 22 is rotated by means of a toothed wheel 24 integral with the collector, which is driven by a pinion 25 in turn driven by a geared motor 26. This geared motor drives all the units or collectors 22 existing in the machine.

En outre, l'arrêt de la rotation de chaque col­lecteur 22 se produit de telle sorte que les bras 15 sont arrêtés par dessus et par dessous de la pièce 4, tel que l'on voit sur la Fig. 4, afin qu'en tournant d'un pas la roue 2 la pièce 4 ne vienne heurter les bras 15.Furthermore, the rotation of each collector 22 is stopped so that the arms 15 are stopped above and below the part 4, as seen in FIG. 4, so that by turning the wheel 2 one step, the part 4 does not strike the arms 15.

D'autre part, afin de faciliter l'entretien et de pouvoir vérifier l'état des bras 15 sans besoin de pénétrer dans la cuve 16, les conduites 20 qui supportent les collec­teurs 22 sont reliées par un bout tubulaire 35 à un pro­longement 27 de l'arbre commun 11 des deux roues 2 et 3. Ainsi, en actionnant le pignon 28 solidaire de ce bout 25 l'ensemble tourne vers la partie supérieure de la machine permettant alors l'accès à n'importe quel ouvrier placé au côté du dispositif d'alimentation 1.On the other hand, in order to facilitate maintenance and to be able to check the condition of the arms 15 without the need to enter the tank 16, the conduits 20 which support the collectors 22 are connected by a tubular end 35 to an extension 27 of the common shaft 11 of the two wheels 2 and 3. Thus, by actuating the pinion 28 integral with this end 25 the assembly turns towards the upper part of the machine then allowing access to any worker placed at the side of the feeding device 1.

L'entraînement du pignon 28 a été représenté dans la Fig. 3 par une chaîne 29 et un motoréducteur 30, mais ce positionnement n'est pas limitatif car il pourrait être fait aussi au moyen d'un cylindre pneumatique ou d'un cylindre hydraulique.The drive of the pinion 28 has been shown in FIG. 3 by a chain 29 and a geared motor 30, but this positioning is not limiting since it could also be done by means of a pneumatic cylinder or a hydraulic cylinder.

Il est évident qu'avant de faire basculer l'en­semble des collecteurs communs 22 de la manière décrite il faut dévisser les brides 31 de la conduite 20 repré­sentées dans la Fig. 4 afin de détacher le tuyau.It is obvious that before switching all of the common collectors 22 in the manner described, it is necessary to unscrew the flanges 31 of the pipe 20 shown in FIG. 4 to detach the hose.

La roue 3 convoie les pièces qui doivent être sé­chées et on y peut voir l'ensemble 91 des bras de souf­flage rotatifs à buses 10, qui est semblable à l'ensemble correspondant de la roue de lavage 2, mais le fluide de traitement, dans ce cas, est l'air comprimé. Ici le méca­nisme d'entraînement 32 est fixé à l'extérieur puisqu'il n'existe pas le problème d'étanchéité posé dans le cas du lavage.The wheel 3 conveys the parts which must be dried and one can see there the assembly 91 of the rotary blowing arms with nozzles 10, which is similar to the corresponding assembly of the washing wheel 2, but the treatment fluid, in this case is compressed air. Here the drive mechanism 32 is fixed to the outside since there is no sealing problem posed in the case of washing.

Dans l'opération de lavage l'on peut disposer préférablement une boîte supplémentaire fixe avec un col­lecteur 33 fixé sur la face de la roue 2 opposée à celle contenant le mécanisme de rotation, afin de laver la face de la pièce 4 qui n'est pas accessible à l'intervention des bras 15 des boîtes tournantes.In the washing operation, it is preferable to have an additional fixed box with a collector 33 fixed on the face of the wheel 2 opposite to that containing the rotation mechanism, in order to wash the face of the part 4 which is not not accessible to the intervention of the arms 15 of the rotating boxes.

Tel que l'on peut parfaitement apprécier dans les Fig. 2 et 4, les pièces 4 sont positionnées de sorte qu'elles dépassent en porte-à-faux le plan de la roue 2. Dans chaque extraction de travail la pièce 4 est logée entre les bras 15 et ceux-ci vont en l'entourant par la rotaton du collecteur commun 22 pendant la phase opéra­toire dans cette station de travail.As can be perfectly appreciated in Figs. 2 and 4, the parts 4 are positioned so that they overhang the plane of the wheel 2. In each working extraction, the part 4 is housed between the arms 15 and these go therein. surrounding by the rotaton of the common collector 22 during the operating phase in this work station.
