Description

L'invention concerne un dispositif pour le ponçage et/ou l'égrenage de pièces en bois, ledit dispositif comportant une cuve fermée contenant un matériau abrasif dans laquelle est prévu un support de pièces, ledit support étant animé de mouvements vibratoires.The invention relates to a device for sanding and / or ginning wooden parts, said device comprising a closed tank containing an abrasive material in which a workpiece support is provided, said support being driven by vibratory movements.

Le processus de fabrication des meubles en bois est maintenant automatisé ; par contre, les opérations de finition, telles que ponçage, égrenage, etc. n'ont pas encore trouvé de solutions satisfaisantes et nécessitent, dans la plupart des cas, une intervention manuelle.The manufacturing process for wooden furniture is now automated; on the other hand, finishing operations, such as sanding, ginning, etc. have not yet found satisfactory solutions and in most cases require manual intervention.

Le ponçage, technique bien connue, et l'égrenage, qui consiste à faire disparaître les irrégularités qui apparaissent lors de la teinture ou du vernissage des bois, par suite du redressement des fibres, sont des opérations longues et d'autant plus délicates que les surfaces sont travaillées.Sanding, a well-known technique, and ginning, which consists in removing the irregularities which appear during the staining or varnishing of wood, as a result of the straightening of the fibers, are long operations and all the more delicate as the surfaces are worked.

On a essayé de mécaniser l'égrenage en utilisant des brosses métalliques, mais ce procédé présentait l'inconvénient d'arrondir exagérément les angles vifs.We tried to mechanize the ginning using wire brushes, but this method had the disadvantage of excessively rounding the sharp corners.

Selon un autre procédé décrit dans la demande de brevet allemand publiée n° 25 20 399, la pièce à polir est fixée à un support pénétrant dans une enceinte contenant un matériau abrasif. Le support est soumis à des mouvements alternatifs longitudinaux et de rotation. La pièce, partiellement immergée dans le matériau abrasif, est successivement poncée ou égrenée sur toutes ses faces. Afin de permettre la sortie des pièces traitées et leur remplacement par de nouvelles, on a prévu un compartiment dans lequel pénètre le matériau abrasif lors du basculement de l'enceinte. Ce basculement a lieu autour de paliers fixés à l'extrémité de l'enceinte opposée à celle maintenant le support. Selon le mode de réalisation représenté, le dispositif est prévu pour traiter une chaise.According to another method described in the patent application German published n ° 25 20 399, the polishing piece is fixed to a support penetrating into an enclosure containing an abrasive material. The support is subjected to alternating longitudinal and rotational movements. The part, partially immersed in the abrasive material, is successively sanded or ginned on all its faces. In order to allow the treated parts to leave and replace them with new ones, a compartment has been provided into which the abrasive material penetrates when the enclosure tilts. This tilting takes place around bearings fixed at the end of the enclosure opposite to that holding the support. According to the embodiment shown, the device is designed to treat a chair.

Par suite de l'immobilité du matériau abrasif et des mouvements de la pièce en traitement, il se produit un tassement de l'abrasif qui freine les mouvements du support et qui peut même entraîner la détérioration de l'objet traité. En outre, le basculement de l'enceinte pour son déchargement et son chargement nécessite des moyens puissants, par suite de la masse d'abrasif et de la position de l'axe de rotation.As a result of the immobility of the abrasive material and the movements of the part being treated, there is a compaction of the abrasive which slows down the movements of the support and which can even cause deterioration of the object treated. In addition, the tilting of the enclosure for unloading and loading requires powerful means, due to the mass of abrasive and the position of the axis of rotation.

Le dispositif, selon l'invention, met en oeuvre un procédé de ponçage et/ou d'égrenage semblable à celui utilisé dans la demande citée, mais est conçu de manière à éviter les effets de tassement du matériau abrasif et à supprimer les déplacements importants du matériau lors du chargement ou du déchargement des pièces traitées.The device according to the invention implements a sanding and / or ginning process similar to that used in the cited application, but is designed so as to avoid the effects of compaction of the abrasive material and to eliminate large displacements of material when loading or unloading treated parts.

Les explications et figures données ci-après, à titre d'exemples, permettront de comprendre comment l'invention peut être réalisée.The explanations and figures given below, by way of examples, will make it possible to understand how the invention can be implemented.

Les figures 1, 2, 3 montrent différentes vues d'un dispositif pour le ponçage et/ou l'égrenage de pièces en bois selon une forme de réalisation de l'invention.Figures 1, 2, 3 show different views of a device for sanding and / or ginning of wooden parts according to an embodiment of the invention.

Le dispositif comprend une cuve intérieure 1 d'axe horizontal cylindrique ou polygonale, coaxiale à une cuve extérieure 2 cylindrique. Cet ensemble est réalisé sous la forme d'une cuve à double paroi latérale. La paroi latérale 2 coopère avec des moyens d'entraînement en rotation constitués de rouleaux ou galets d'axes horizontaux 3, 4 montés sur un berceau 5 fixé au sol. Les rouleaux ou galets sont solidaires d'axes ayant une longueur au moins égale à celle de la cuve et tournent dans des paliers 6, 7 fixés sur le berceau. Aux extrémités extérieures des rouleaux ou galets sont prévus des flasques 8 qui empt- chent les déplacements longitudinaux. Selon la réalisation représentée, un des axes des rouleaux est entrainé et l'autre fou. Ainsi, l'axe 3 est entraîné par un moteur 9 par l'intermédiaire d'un réducteur 10 et d'un accouplement 11. De préférence, le moteur 9 est un moteur avec variation de vitesse.The device comprises an internal tank 1 of horizontal cylindrical or polygonal axis, coaxial with an external tank 2 cylindrical. This assembly is produced in the form of a tank with double side wall. The side wall 2 cooperates with rotational drive means consisting of rollers or rollers with horizontal axes 3, 4 mounted on a cradle 5 fixed to the ground. The rollers or rollers are integral with axes having a length at least equal to that of the tank and rotate in bearings 6, 7 fixed on the cradle. Flanges 8 are provided at the outer ends of the rollers or rollers which prevent longitudinal movements. According to the embodiment shown, one of the axes of the rollers is driven and the other idler. Thus, the axis 3 is driven by a motor 9 via a reduction gear 10 and a coupling 11. Preferably, the motor 9 is a motor with speed variation.

Un des fonds 12 de la cuve intérieure 1, directement accessible, est muni d'une porte 13 semi-circulaire maintenue fermée par un verrou de porte 14 et portant dans l'axe de la cuve un raccord 23 pour le branchement à un dispositif d'aspiration ou de soufflageo La cuve intérieure 1 présente sur toute sa longueur une trappe 15 définie approximativement entre les deux fonds 12, 16 et deux génératrices 17, 18 situées entre le bas de porte 19 et la paroi latérale de la cuve 1 par rapport à son axe, la corde joignant les génératrices 17, 18 étant approximativement parallèle au bas de porte 19. Un abattant 20 est articulé selon, par exemple, la génératrice 17 et est maintenu en position fermée par un verrou de trappe 21. La largeur de l'abattant 20 est telle que celui-ci, lorsqu'il est ouvert (figure 1), vient reposer par son bord 22 contre la surface latérale interne de la paroi extérieure 2, partageant ainsi le volume compris entre les deux parois. La fonction de cet abattant sera expliquée ultérieurement.One of the bottoms 12 of the inner tank 1, directly accessible, is provided with a semi-circular door 13 kept closed by a door latch 14 and carrying a fitting 23 in the axis of the tank for connection to a device d suction or blowing The inner tank 1 has over its entire length a hatch 15 defined approximately between the two bottoms 12, 16 and two generators 17, 18 located between the bottom of the door 19 and the side wall of the tank 1 relative to its axis, the cord joining the generators 17, 18 being approximately parallel to the bottom of the door 19. A flap 20 is articulated according to, for example, the generator 17 and is held in the closed position by a trap latch 21. The width of the flap 20 is such that the latter, when open (Figure 1), comes to rest by its edge 22 against the inner lateral surface of the outer wall 2, thus sharing the volume between the two walls. The function of this flap will be explained later.

Le fond 16 de la cuve intérieure 1 présente dans l'axe une ouverture 24 par laquelle passe un équipage mobile 25 à une extrémité duquel est fixé le support 44 des pièces à traiter.The bottom 16 of the inner tank 1 has in the axis an opening 24 through which passes a movable assembly 25 at one end of which is fixed the support 44 of the parts to be treated.

Selon la réalisation représentée figures 2 et 3, l'équipage mobile 25 est constitué d'un arbre cylindrique 26 maintenu, à son extrémité opposée à celle portant le support, dans une rotule 27 dont le palier est fixé par une plaque support 28 à un châssis formé par le carénage 29 de l'équipage mobile, le carénage étant fixé au fond 16 de la cuve. La rotule est protégée des poussières par des soufflets 30.According to the embodiment shown in Figures 2 and 3, the movable assembly 25 consists of a cylindrical shaft 26 maintained, at its end opposite to that carrying the support, in a ball joint 27 whose bearing is fixed by a support plate 28 to a chassis formed by the fairing 29 of the movable assembly, the fairing being fixed to the bottom 16 of the tank. The ball joint is protected from dust by bellows 30.

L'équipage mobile 25 est mis en mouvement par un dispositif d'entraînement qui, dans l'exemple de réalisation des figures 2 et 3, comprend des biellettes de maintien et des moyens d'entraînement linéaire alternatif.The moving element 25 is set in motion by a drive device which, in the embodiment of FIGS. 2 and 3, comprises holding rods and alternative linear drive means.

L'arbre 26 est maintenu près de l'extrémité portant le support et extérieurement à la cuve par un jeu de deux biellettes 31, 32 disposées respectivement dans des plans vertical et horizontal par rapport au bâti 50 La biellette verticale 31 porte à une extrémité un étrier 33 dont les branches coopèrent avec des tourillons cylindriques 34 fixés diamétralement sur l'arbre 26. L'autre extrémité de la biellette est mobile autour d'un axe a, b, ou c fixé dans une console 35 solidaire du fond de cuve.The shaft 26 is held near the end carrying the support and outside the tank by a set of two links 31, 32 arranged respectively in vertical and horizontal planes relative to the frame 50 The vertical link 31 carries at one end a stirrup 33 whose branches cooperate with cylindrical pins 34 fixed diametrically on the shaft 26. The other end of the link is movable around an axis a, b, or c fixed in a console 35 secured to the bottom of the tank.

Selon une forme de réalisation, les points d'articulation a, b, c de la biellette verticale sur la console lui donnent une inclinaison comprise entre 90 et 45° par rapport à l'horizontale matérialisée par l'axe de l'équipage mobile. La biellette horizontale 32 est fixée à 90° de la biellette verticale 31, une des extrémités étant fixée sur l'arbre 26 par l'intermédiaire d'un étrier 36, et l' autre extrémité étant fixée à une console 37 solidaire du fond de cuve 16.According to one embodiment, the points of articulation a, b, c of the vertical link on the console give it an inclination of between 90 and 45 ° relative to the horizontal materialized by the axis of the moving assembly. The horizontal link 32 is fixed at 90 ° to the vertical link 31, one of the ends being fixed to the shaft 26 by means of a stirrup 36, and the other end being fixed to a console 37 secured to the bottom of tank 16.

Cette console présente également plusieurs points d'articulation a, b, c permettant d'obtenir une inclinaison comprise entre 90 et 45° par rapport à l'horizontale.This console also has several points of articulation a, b, c making it possible to obtain an inclination of between 90 and 45 ° relative to the horizontal.

L'arbre 26 est entraîné longitudinalement par des moyens d'entraînement linéaire alternatif 38 comportant un moteur électrique 39, fixé sur le fond de la cuve. L'arbre du moteur est muni d'un excentrique 40 coopérant avec l'alésage cylindrique du pied d'une bielle 41 dont la tête entraîne un étrier 42 fixé sur l'arbre 25.The shaft 26 is driven longitudinally by alternating linear drive means 38 comprising an electric motor 39, fixed to the bottom of the tank. The motor shaft is provided with an eccentric 40 cooperating with the cylindrical bore of the foot of a connecting rod 41 whose head drives a stirrup 42 fixed on the shaft 25.

La mise en service du moteur 39 entraine l'équipage mobile 25 dans un mouvement vibratoire qui se décompose selon trois axes rectangulaires dont deux sont déterminés par les biellettes 31, 32 et le troisième, par l'axe de l' équipage mobile 25. L'amplitude du mouvement selon les composantes verticale et horizontale est réglable par déplacement du point d'accrochage a, b, c des biellettes sur les consoles. Ces amplitudes augmentent avec l'inclinaison des bielletteso L'extrémité du carénage 29 porte un collecteur de courant rotatif 43 permettant l'alimentation du moteur 390The commissioning of the motor 39 drives the moving element 25 in a vibratory movement which breaks down along three rectangular axes, two of which are determined by the links 31, 32 and the third, by the axis of the moving element 25. L amplitude of movement according to the vertical and horizontal components is adjustable by moving the attachment point a, b, c of the rods on the consoles. These amplitudes increase with the inclination of the links The end of the fairing 29 carries a rotary current collector 43 allowing the power to the motor 390

L'équipage mobile 25 porte à son extrémité libre des moyens de fixation amovible du support de pièces 44. Ces moyens sont constitués par une bride 45 fixée à l'extrémité de l'arbre 26 sur laquelle vient se boulonner une traverse 46 du support. Le passage de l'arbre 26 dans l'ouverture 24 du fond 16 de cuve est rendu étanche par un soufflet d'étanchéité 47 dont les bords sont respectivement fixés à la bride 45 de l'arbre 26 et à une collerette 48 fixée sur le bord de l'ouverture 240The movable element 25 carries at its free end means for removable attachment of the workpiece support 44. These means consist of a flange 45 fixed to the end of the shaft 26 onto which a crosspiece 46 of the support is bolted. The passage of the shaft 26 in the opening 24 of the bottom 16 of the tank is sealed by a sealing bellows 47 whose edges are respectively fixed to the flange 45 of the shaft 26 and to a flange 48 fixed on the edge of opening 240

Le support de pièces représenté figures 5 et 6 est plus particulièrement destiné à maintenir des chaises (figurées en traits mixtes) par leur cadre et permet le traitement simultané de deux chaises.The workpiece support shown in Figures 5 and 6 is more particularly intended to hold chairs (shown in phantom) by their frame and allows the simultaneous treatment of two chairs.

La traverse 46 porte symétriquement par rapport à son milieu deux colonnes 49, 50 parallèles formant avec elle une pièce en U. A une distance de la traverse au moins égale à la hauteur du dossier de chaise est fixé un cadre de fixation 51 constitué de deux longerons 52, 53 parallèles reliés par des entretoises 54, 55. La distance entre les entretoises est telle qu'elle correspond approximativement à la distance intérieure entre deux bagues 56, 57 susceptibles de coopérer avec les colonnes 49, 50. Les éléments du cadre de fixation 51 sont symétriques par rapport à l'axe de symétrie passant par le centre des deux colonnes.The cross member 46 carries symmetrically with respect to its middle two parallel columns 49, 50 forming with it a U-shaped part. At a distance from the cross member at least equal to the height of the chair backrest is fixed a fixing frame 51 consisting of two longitudinal beams 52, 53 connected by spacers 54, 55. The distance between the spacers is such that it corresponds approximately to the interior distance between two rings 56, 57 capable of cooperating with the columns 49, 50. The elements of the frame attachment 51 are symmetrical with respect to the axis of symmetry passing through the center of the two columns.

Les extrémités dépassantes des longerons portent des moyens de blocage du cadre de chaise. Ces moyens sont constitués d'un collier 58 susceptible de coulisser sur une extrémité libre d'un longeron et portant un levier à excentrique 59 destiné à prendre appui sur un côté 60 du cadre de chaise, le collier étant bloqué sur le longeron par coincement ; et d'une butée 61 fixée à l'autre extrémité libre du longeron et maintenant le côté opposé 62 du cadre de chaise.The projecting ends of the side members carry means for locking the chair frame. These means consist of a collar 58 capable of sliding on a free end of a spar and carrying an eccentric lever 59 intended to bear on one side 60 of the chair frame, the collar being blocked on the spar by wedging; and a stop 61 fixed to the other free end of the side member and maintaining the opposite side 62 of the chair frame.

Les bagues 56 et 57 auxquelles est fixé le cadre de fixation 51 sont maintenues sur les colonnes, soit de façon amovible par des moyens de serrage connus, soit de façon permanente par soudure, comme montré sur les figures 5, 6.The rings 56 and 57 to which the fixing frame 51 is fixed are held on the columns, either removably by known clamping means, or permanently by welding, as shown in FIGS. 5, 6.

Pour le traitement simultané d'une deuxième chaise, on place sur l'extrémité des colonnes un deuxième cadre de fixation 63 semblable au premier 51, mais dont les bagues sont maintenues à une extrémité par un dispositif expansible de blocage 64 qui comprend, de manière connue, une bague élastique 65 susceptible d'être comprimée longitudinalement entre une butée fixe 66 et une butée mobile 67 par l'intermédiaire d'un excentrique 68.For the simultaneous treatment of a second chair, a second fixing frame 63 similar to the first 51 is placed on the end of the columns, but the rings of which are held at one end by an expandable locking device 64 which comprises, so known, an elastic ring 65 capable of being compressed longitudinally between a fixed stop 66 and a movable stop 67 by means of an eccentric 68.

Selon une autre forme de réalisation du dispositif d'entraînement de l'équipage mobile, représenté figure 4, celui-ci est constitué de trois générateurs de vibrations 69, 70, 71 montés sur une structure 72 fixée au carénage 29 par l'intermédiaire de plots en caoutchouc 73.According to another embodiment of the device for driving the mobile assembly, shown in FIG. 4, it consists of three vibration generators 69, 70, 71 mounted on a structure 72 fixed to the fairing 29 by means of rubber pads 73.

Les générateurs sont disposés sur la structure de façon que leurs actions s'exercent selon trois directions perpendiculaires entre elles.The generators are arranged on the structure so that their actions are exerted in three directions perpendicular to each other.

La structure 72 est munie d'un arbre 74 traversant le fond 16 de la cuve 1 et portant, comme dans l'exemple précédent, un support 44 de pièces à traiter.The structure 72 is provided with a shaft 74 passing through the bottom 16 of the tank 1 and carrying, as in the previous example, a support 44 of parts to be treated.

Les générateurs de vibration sont constitués, par exemple, par des moteurs à balourd.The vibration generators are constituted, for example, by unbalance motors.

Selon une variante, on prévoit à l'extrémité libre de l'équipage mobile un contrepoids 75 d'équilibrage des pièces à traiter.Alternatively, there is provided at the free end of the movable assembly a counterweight 75 for balancing the parts to be treated.

De préférence, le matériau abrasif se présente sous forme de billes ou de pastilles qui remplissent au moins à moitié la cuve intérieure.Preferably, the abrasive material is in the form of balls or pellets which fill at least half the inner tank.

La mise en oeuvre du dispositif pour le ponçage et/ou l'égrenage de pièces en bois est ci-après décrite.The implementation of the device for sanding and / or ginning of wooden parts is described below.

On admet le dispositif à l'arrêt, la charge de matériau abrasif étant contenue dans la cuve intérieure 1, l'abattant 20 de trappe étant en position fermée et retenu par le verrou de trappe 21, la porte 13 étant fermée par le verrou de porte 14.The device is allowed to stop, the load of abrasive material being contained in the inner tank 1, the flap 20 of the flap being in the closed position and retained by the flap latch 21, the door 13 being closed by the latch door 14.

On amène le bas de porte 19 approximativement en position horizontale par mise en marche du moteur 9 qui entraîne le rouleau 3. On arrête alors la rotation de la cuve et on ouvre l'abattant 20. Le matériau abrasif s'écoule par la trappe 15 dans l'espace compris entre la paroi de la cuve intérieure 1 et la paroi extérieure 2, le bord 22 de l'abattant 20 reposant contre la surface intérieure de la paroi 2 limite l'écoulement du matériau sur un c8té. Le vidage peut être aidé par la mise en oeuvre d'un mouvement alternatif de la cuve de faible amplitude. Le niveau du matériau abrasif s'abaisse au-dessous du bas de la porte et permet l'ouverture de la porte 13. On met en place le support 44 de pièces sur lequel sont fixées deux chaises à traiter. On referme la porte 13 et le moteur 9 est mis en marche pour faire tourner la cuve dans le sens des aiguilles d'une montre (pour la réalisation représentée dans laquelle l'ouverture de l'abattant se fait de gauche à droite figure 1). Le matériau abrasif est retenu par l' abattant 20 et s'écoule dans la cuve 1. Lorsque la cuve a fait un demi-tour et que l'abattant est venu dans la position diamétralement opposée à celle montrée sur la figure 1, celui-ci vient s'appliquer contre la trappe 15 et est verrouillé par le verrou de trappe 21. On met alors en action le dispositif d'entraînement de l'équipage mobile tout en faisant effectuer à la cuve une rotation alternée.The door bottom 19 is brought into an approximately horizontal position by starting the motor 9 which drives the roller 3. The rotation of the tank is then stopped and the flap 20 is opened. The abrasive material flows through the hatch 15 in the space between the wall of the inner tank 1 and the outer wall 2, the edge 22 of the flap 20 resting against the inner surface of the wall 2 limits the flow of the material on one side. The emptying can be helped by the implementation of an alternating movement of the tank of small amplitude. The level of the abrasive material drops below the bottom of the door and allows the door 13 to be opened. The support 44 for parts is placed on which two chairs to be treated are fixed. We close the door 13 and the motor 9 is started to rotate the tank clockwise (for the embodiment shown in which the flap is opened from left to right Figure 1) . The abrasive material is retained by the flap 20 and flows into the tank 1. When the tank has made a U-turn and the flap has come into the position diametrically opposite to that shown in FIG. 1, this this is applied against the hatch 15 and is locked by the hatch lock 21. The drive device of the moving assembly is then put into action while by making the tank rotate alternately.

Lorsque le traitement est jugé suffisant, on arrête le moteur d'entraînement 39 de l'équipage mobile et on amène le bas de la porte en position horizontale. Ou ouvre la trappe pour évacuer le matériau abrasif de la cuve intérieure et l'on sort le support de pièces 44.When the processing is deemed sufficient, the drive motor 39 of the moving assembly is stopped and the bottom of the door is brought to a horizontal position. Or open the hatch to evacuate the abrasive material from the inner tank and take out the workpiece support 44.

Selon les exemples de réalisation décrits : la fréquence de vibration est comprise entre 3 et 30 hertz et l'amplitude entre zéro et + 20 mm.According to the embodiments described: the vibration frequency is between 3 and 30 hertz and the amplitude between zero and + 20 mm.

Les poussières résultant du traitement sont évacuées par un appareil aspirateur par l'intermédiaire du raccord 230 Ce même raccord permet le décollement des poussières accrochées sur le matériau abrasif par soufflage.The dust resulting from the treatment is evacuated by a vacuum device via the connection 230. This same connection allows the separation of the dust attached to the abrasive material by blowing.

La figure 7 illustre une variante à caractère optimal du mode de réalisation de l'invention.FIG. 7 illustrates an optimal variant of the embodiment of the invention.

Dans cette variante, les organes précédemment décrits portent les mêmes repères. La différence réside dans le fait que le berceau 70 sur lequel repose l'ensemble tournant est lui-même mobile par rotation autour de l'axe 71 soutenu par des paliers (non représentés) solidaires d'une extrémité du berceau fixe 72. L'autre extrémité du berceau 76 est équipée d'un ou plusieurs vérins 73 dont la (ou les) partie (s) mobile (s) 74 est (sont) articulée(s) en 75 au berceau 70.In this variant, the previously described members have the same references. The difference lies in the fact that the cradle 70 on which the rotary assembly rests is itself mobile by rotation about the axis 71 supported by bearings (not shown) integral with one end of the fixed cradle 72. The other end of the cradle 76 is equipped with one or more jacks 73, the movable part (s) 74 of which are articulated at 75 to the cradle 70.

La mise en oeuvre du ou des vérins 73 par des moyens bien connus, par exemple hydrauliques, permet d'incliner l'ensemble tournant de la position horizontale à la position inclinée et inversement. Cette opération d'inclinaison suivant l'axe longitudinal peut se faire tout en effectuant la rotation de la cuve et la vibration du support.The implementation of the jack or jacks 73 by well known means, for example hydraulic, makes it possible to tilt the rotating assembly from the horizontal position to the inclined position and vice versa. This tilting operation along the longitudinal axis can be done while rotating the tank and vibrating the support.

Le dispositif suivant l'invention permet de traiter globalement l'objet. Il utilise une technologie courante et ne nécessite que peu d'outillages spécifiques. Son coût est faible et son entretien simple. Il peut fonctionner avec toute une variété de produits abrasifs qui peuvent être choisis en fonction de l'emploieThe device according to the invention makes it possible to treat the object globally. It uses current technology and requires only a few specific tools. Its cost is low and its maintenance simple. It can work with a variety of abrasive products which can be chosen according to the use

La rotation de l'ensemble cuve et objet à traiter permet, d'une part, le brassage de l'abrasif (donc évite le tassement) et, d'autre part, le passage dans l'abrasif de toutes les parties de l'objet à traiter même si la cuve n'est pas entièrement remplie d'abrasif. Ces avantages sont encore améliorés lorsque l'on incline le berceau.The rotation of the tank and the object to be treated allows, on the one hand, the mixing of the abrasive (therefore avoids compaction) and, on the other hand, the passage through the abrasive of all the parts of the object to be treated even if the tank is not completely filled with abrasive. These advantages are further improved when the cradle is tilted.

Pour atténuer le bruit et l'usure de l'enceinte, la paroi intérieure peut être revêtue de caoutchouc pulvérisé au pistolet ou d'une chemise amovible, par exemple collée.To reduce noise and wear on the enclosure, the interior wall can be coated with spray-sprayed rubber or with a removable jacket, for example glued.

L'invention trouve une application particulièrement intéressante dans l'égrenage et le ponçage d'objets en bois et en particulier des meublesoThe invention finds a particularly interesting application in the ginning and sanding of wooden objects and in particular furniture.
