Abstract

Each rotating brush 3 is displaced alternately by a jack 18 so as to be displaced along guides 9 oriented transversely to the displacement direction of the conveyor belt 1 which supports the elements to be processed, so that it is the entire surface of the latter which is cleaned in spite of their complex profile. A motor 26 associated with an adjustment mechanism makes it possible to modify the height of the brush above the belt 1 as a function of the thickness of the moulded elements.

Description

On sait qu'au cours du processus de ponçage-polissage et de vernissage du bois, il y a lieu de prévoir une opération d'égrenage qui intervient habituellement sur la pièce brute avant mise en teinte ou après une première enduction de vernis et qui a pour but d'éliminer les aspérités superficielles. Cette opération est en général effectuée à l'aide d'une machine égreneuse pourvue de brosses rotatives au contact desquelles on fait passer les pièces a traiter, disposées à cet effet sur un transporteur oriente transversalement à l'axe des brosses. It is known that during the sanding-polishing and varnishing process of the wood, it is necessary to provide for a ginning operation which usually takes place on the raw part before coloring or after a first coating of varnish and which has to eliminate surface roughness. This operation is generally carried out using a ginning machine provided with rotary brushes in contact with which the parts to be treated are passed, arranged for this purpose on a conveyor oriented transversely to the axis of the brushes.

Les machines de ce type donnent entière satifaction lorsqu'on a affaire à des pièces planes en forme de panneaux. Par contre les résultats sont trams imparfaits quand il s'agit d'éléments de meubles en bois massif moulures ; on conçoit qu'en pareil cas les parties en saillie des éléments sont bien polies alors que les parties en creux ou les chants des pièces ne le sont pas. Machines of this type give full satisfaction when dealing with flat pieces in the form of panels. By cons the results are trams imperfect when it comes to solid wood furniture moldings; it is understood that in such a case the projecting parts of the elements are well polished while the recessed parts or the edges of the parts are not.

C'est à cet inconvénient qu'entend principalement remédier la presente invention, laquelle consiste essentiellement a déplacer alternativement, suivant une direction orientée perpendiculairement au sens de déplacement des -elEments à traiter, le point d'application de la périphérie utile des brosses rotatives sur la paroi des éléments précités. It is to this drawback that the present invention mainly intends to remedy, which essentially consists in alternately moving, in a direction oriented perpendicular to the direction of movement of the elements to be treated, the point of application of the useful periphery of the rotary brushes on the wall of the aforementioned elements.

Conforineffimes- a un mode de mise en oeuvre préféré de la disposition qui preède, la broche courante qui supporte chacune des brosses de la machine, ainsi que le mécanisme qui assure l'entralnement en rotation de ledit broche, sont mobiles le long de guides orientes transversalement au-dessus du transporteur destine au de placement des pinces égrener, l'un des paliers associes a ladite broche étant attele à l'organe mobile d'un vérin hydraulique ou pneumatique de commande, alimenté cy.liquement en vue d'impartir à l'ensemble mobile broche-mecanisme d'entranement un mouvement alternatif oriente perpendiculairement au sens de déplacement du transporteur précité.  Conforineffimes- has a preferred embodiment of the foregoing arrangement, the current spindle which supports each of the brushes of the machine, as well as the mechanism which ensures the rotational entrainment of said spindle, are movable along oriented guides transversely above the conveyor intended for placing the gripping pliers, one of the bearings associated with said spindle being coupled to the movable member of a hydraulic or pneumatic control cylinder, supplied cyclically in order to impart to the mobile spindle-drive mechanism reciprocating movement orients perpendicular to the direction of movement of the aforementioned conveyor.

Selon une autre disposition remarquable de la machine suivant l'invention, les guides transversaux et le vérin de commande sont fixes sur des supports mobiles verticalement, afin de permettre le réglage de la position des brosses au-dessus du transporteur en fonction de ltépaisseur des éléments moulures à traiter. According to another remarkable arrangement of the machine according to the invention, the transverse guides and the control cylinder are fixed on vertically movable supports, in order to allow the position of the brushes to be adjusted above the conveyor as a function of the thickness of the elements. moldings to be treated.

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 vue schématique en perspective illustrant l'agencement général d'une machine égreneuse établie conformément à 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 schematic perspective view illustrating the general arrangement of a ginning machine established in accordance with the invention.

Fig. 2 est une coupe à plus grande échelle suivant le plan indiqué en Il-Il en fig. 1. Fig. 2 is a section on a larger scale along the plane indicated in Il-Il in fig. 1.

Sur ce dessin, la référence 1 désigne un transporteur formé par un tapis sans fin ajouré, animé d'un mouvement longitudinal continu et dont le brin supérieur vient s'appliquer contre un caisson d'aspiration 2 propre à assurer, à la façon en soi connue, la retenue des pièces à égrener contre le tapis précité au cours du déplacement de celui-ci, et ce en dépit de l'action des brosses 3. Celles-ci ont été supposées au nombre de trois dans l'exemple de réalisation envisagé, seule l'une d'elles ayant été détaillée. In this drawing, the reference 1 designates a conveyor formed by an openwork endless belt, animated by a continuous longitudinal movement and the upper strand of which is applied against a suction box 2 suitable for ensuring, in the manner in itself known, the retention of the parts to be meshed against the aforementioned carpet during the movement thereof, despite the action of the brushes 3. These were assumed to be three in number in the embodiment envisaged , only one of them having been detailed.

Comme plus particulièrement montre en fig. 2, chaque brosse 3 est portée par une broche 4 supportée par des paliers 5 et 6. le palier 5 est fixé sur une travers pourvue a ses extrémités d'oreilles 8 (fig. 1) engagées à coulissement le long de deux guides 9 orientés parallèlement à la broche 4. De la même manière, le palier 6 est porte par une semelle 10 dotée d'oreilles 11 montées à coulissement sur les mêmes guides 9. En arrière du palier 6, la broche 4 est accouplée à l'arbre de sortie d'un moto-réducteur 12 fixe sur la semelle 10 ; l'arbre d'entrée de ce moto-réducteur 12 est relie, par une transmission logée dans un carter vertical 13, à un moteur d'entratnement 14 porte par ledit carter. As more particularly shown in fig. 2, each brush 3 is carried by a spindle 4 supported by bearings 5 and 6. the bearing 5 is fixed on a crosspiece provided at its ear ends 8 (fig. 1) slidably engaged along two guides 9 oriented parallel to the spindle 4. In the same way, the bearing 6 is carried by a sole 10 provided with ears 11 mounted to slide on the same guides 9. Behind the bearing 6, the spindle 4 is coupled to the shaft of output of a geared motor 12 fixed on the sole 10; the input shaft of this geared motor 12 is connected, by a transmission housed in a vertical casing 13, to a drive motor 14 carried by said casing.

On conçoit dans ces conditions que l'ensemble formé par la brosse 3, sa broche-support 4 et le mécanisme d'entraînement 12-13-14 est susceptible de se déplacer longitudinalement le long des guides 9, dans un plan orienté perpendiculairement à l'axe du transporteur forme par le tapis 1 et le caisson aspirant 2. It is therefore conceivable that the assembly formed by the brush 3, its support pin 4 and the drive mechanism 12-13-14 is capable of moving longitudinally along the guides 9, in a plane oriented perpendicular to the the axis of the conveyor formed by the belt 1 and the suction box 2.

Comme montré en fig. 2, les guides 9 s'étendent au-delà de la semelle mobile 10 pour être fixes, à l'aide de manchons 15, à une entretoise 16. Un ensemble 15-16 analogue est prévu au niveau de ltextrémité opposée des guides 9, comme montré en fig. 1, étant observé que cette entretoise 16 est dans sa partie centrale rendue solidaire d'un petit plateau 17 (fig. 2) formant support pour un vérin 18 du type à double effet et à fonctionnement pneumatique ou hydraulique. As shown in fig. 2, the guides 9 extend beyond the movable base 10 to be fixed, using sleeves 15, to a spacer 16. A similar assembly 15-16 is provided at the opposite end of the guides 9, as shown in fig. 1, it being observed that this spacer 16 is in its central part made integral with a small plate 17 (fig. 2) forming a support for a jack 18 of the double-acting type and with pneumatic or hydraulic operation.

L'organe mobile 18a de ce vérin 18 est relie par-une équerre 19 à la traverse 7 sus-mentionnée. The movable member 18a of this jack 18 is connected by a bracket 19 to the cross-member 7 mentioned above.

Si l'on suppose que le vérin 18 est alimenté alternativement, suivant un cycle approprié, à travers l'une et l'autre de ses deux extrémités, son organe mobile 18e et l'ensemble de la brosse 3 et de son mécanisme d'actionnement sont animés d'un déplacement en va-et-vient par rapport à la surface du transporteur. Dans ces conditions, les éléments de meubles disposés sur le tapis 1 afin d'être successivement amenés aux brosses 3 de la machine sont soumis à une opération d'égrenage parfaitement efficace, le déplacement transversal alternatif des brosses par rapport à la surface supérieure desdits éléments assurant le travail de toute cette surface supérieure en dépit du profil mouluré présenté par les éléments à traiter. If it is assumed that the jack 18 is supplied alternately, according to an appropriate cycle, through one and the other of its two ends, its movable member 18e and the assembly of the brush 3 and its mechanism actuation are driven back and forth relative to the surface of the conveyor. Under these conditions, the furniture elements placed on the carpet 1 in order to be successively brought to the brushes 3 of the machine are subjected to a perfectly effective ginning operation, the alternating transverse movement of the brushes relative to the upper surface of said elements ensuring the work of all this upper surface despite the molded profile presented by the elements to be treated.

Afin de permettre l'adaptation aisée de la machine à tous les éléments de meubles susceptibles d'être rencontrés, quelle que soit leur épaisseur, on fait comporter a la face inférieure de chacune des entretoises 16 qui portent les guides 9 une colonne verticale 20 engagée dans des manchons fixes de guidage 21-solidaires des montants 22 du bâti de la machine. L'extremite inférieure de chaque colonne 20 est percée d'un taraudage axial borgne 20e à l'interieur duquel se visse une tige filetée 23 ; la base de chacune des tiges 23 est reliée, par un renvoi d'angle 24, à un arbre d'entraînement commun 25 disposé entre les montants 22 et actionné en rotation, dans un sens ou dans l'autre par un moto-réducteur 26 à travers une transmission à chaîne 27. In order to allow the easy adaptation of the machine to all the furniture elements liable to be encountered, whatever their thickness, a vertical column 20 is engaged on the lower face of each of the spacers 16 which carry the guides 9. in fixed guide sleeves 21 integral with the uprights 22 of the machine frame. The lower end of each column 20 is pierced with a blind axial thread 20e inside which is screwed a threaded rod 23; the base of each of the rods 23 is connected, by a bevel gear 24, to a common drive shaft 25 disposed between the uprights 22 and actuated in rotation, in one direction or the other by a gear motor 26 through a chain transmission 27.

On comprend que l'actionnement de ce moto-reducteur 26 permet de déplacer verticalement l'ensemble associé à chacune des brosses 3 de la machine, en permettant l'adaptation de celle-ci a l'epaisseur des éléments de meubles a polir. It is understood that the actuation of this gear motor 26 allows to vertically move the assembly associated with each of the brushes 3 of the machine, allowing the adaptation of the latter to the thickness of the furniture elements to be polished.

Il va de soi qu'un résultat identique serait obtenu en modifiant la hauteur du transporteur 1-2 par rapport aux brosses tournantes 3. It goes without saying that an identical result would be obtained by modifying the height of the conveyor 1-2 relative to the rotating brushes 3.

De la meme manière, en certains cas on peut envisager d'impartir a ce transporteur 1-2 un mouvement alternatif horizontal oriente transversale ment à son axe longitudinal, les brosses rotatives étant alors fixes en position longitudinale. In the same way, in certain cases it is possible to envisage imparting to this conveyor 1-2 a horizontal reciprocating movement oriented transversely to its longitudinal axis, the rotary brushes then being fixed in the longitudinal position.

Il doit d'ailleurs être entendu que la description qui précède nta été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. On comprend en particulier que certaines seulement des brosses rotatives 3 peuvent être animées d'un mouvement horizontal alternatif, les autres restant fixes.  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 equivalents. It will be understood in particular that only some of the rotary brushes 3 can be driven in an alternating horizontal movement, the others remaining fixed.
