Description

DISPOSITIF DE PONÇAGE ET DE DECAPAGE POUR LA MENUISERIE ET L'INDUSTRIE SANDING AND STRIPPING DEVICE FOR JOINERY AND INDUSTRY
La présente invention se rapporte au domaine de la mécanique et plus particulièrement au domaine des outils à bois.The present invention relates to the field of mechanics and more particularly to the field of wood tools.
Elle a plus particulièrement pour objet, un dispositif de ponçage et de décapage pour la menuiserie ou l'ébénisterie permettant le décapage et l'aplanissement du bois tout en assurant un travail réglable en épaisseur et garantissant une complète sécurité pendant l'exécution.It more particularly has for object, a device of sanding and stripping for joinery or cabinet making allowing the stripping and the leveling of the wood while ensuring a work adjustable in thickness and guaranteeing a complete safety during the execution.
On utilise fréquemment des outils électriques pour le travail du bois en adaptant, sur l'axe moteur d'une perceuse électrique, un plateau de polissage ou de ponçage formé d'un portoir et de feuilles de papier abrasif d'épaisseurs différentes. Ces ponceuses sont difficiles à régler car elles sont conçues pour travailler à vitesse constante et lorsque les détails du bois nécessitent un travail en finesse, ce type d'outil convient mal car il décape de trop et entame le bois, ou bien il tourne trop lentement et n'assure pas une découpe suffisante et régulière.Power tools are frequently used for woodworking by adapting, on the motor axis of an electric drill, a polishing or sanding plate formed by a rack and sheets of abrasive paper of different thicknesses. These sanders are difficult to adjust because they are designed to work at a constant speed and when the details of the wood require work in finesse, this type of tool is ill-suited because it scours too much and starts the wood, or else it turns too slowly and does not ensure sufficient and regular cutting.
Le dispositif selon l'invention vise à remédier aux inconvénients des systèmes déjà connus en réalisant un dispositif aisé à manier, facile à régler et assurant une sécurité complète pendant le travail. En outre, il assure un changement aisé des brosses qui effectuent le travail de décapage ou de polissage.The device according to the invention aims to remedy the drawbacks of the systems already known by providing an easy to handle device, easy to adjust and ensuring complete safety during work. In addition, it ensures easy change of the brushes which perform the work of stripping or polishing.
Le dispositif selon l'invention comporte une brosse métallique ou autre matériau dur dont la rotation est assurée par un moteur électrique qui transmet son mouvement par une courroie crantée venant coopérer avec l'axe central de la brosse monté lui-même sur l'axe fixe pourvu de roulements à billes pour en permettre la rotation. La hauteur de la brosse est assurée par une vis de réglage qui permet le déplacement de la brosse dans un plan vertical de manière à attaquer le bois plus ou moins profondément.. La vis de réglage interagit sur un bras extérieur d'entraînement, pivotant autour de l'axe moteur. La brosse est mise en mouvement par l'intermédiaire d'un axe moteur disposé au-dessus de celle-ci et qui reçoit le mouvement grâce à la courroie crantée.The device according to the invention comprises a metal brush or other hard material whose rotation is ensured by an electric motor which transmits its movement by a toothed belt coming to cooperate with the central axis of the brush mounted itself on the fixed axis provided with ball bearings to allow rotation. The height of the brush is ensured by an adjustment screw which allows the displacement of the brush in a vertical plane so as to attack the wood more or less deeply. The adjustment screw interacts on an external drive arm, pivoting around of the motor axis. The brush is set in motion by means of a motor axis placed above it and which receives the movement thanks to the toothed belt.
L'invention consiste donc en un dispositif électrique ou pneumatique entraînant une brosse métallique placée dans un carter protégeant la partie mécanique, présentant sur la partie avant, un capot placé dans un plan perpendiculaire assujetti au bâti et venant tourner dans un évidement disposé en bout du bâti sur lequel l'axe d'entraînement de la brosse et l'axe d'entraînement du moteur permettent la rotation de l'ensemble.The invention therefore consists of an electric or pneumatic device driving a metal brush placed in a casing protecting the mechanical part, having on the front part, a cover placed in a perpendicular plane subject to the frame and coming to rotate in a recess disposed at the end of the frame on which the brush drive axis and the motor drive axis allow the assembly to rotate.
Ce bâti fait partie d'un ensemble métallique rigide de forme allongée portant à la partie supérieure un moyen de préhension tel qu'une poignée et un dispositif de commutation électrique assurant la marche ou l'arrêt du dispositif. Le dispositif de préhension sert également à recevoir les fils d'alimentation.This frame is part of a rigid metallic assembly of elongated shape carrying at the upper part a gripping means such as a handle and an electrical switching device ensuring the start or stop of the device. The gripping device also serves to receive the supply wires.
Dans l'évidement du bras latéral, on a disposé un axe d'entraînement cranté monté sur un axe métallique qui reçoit la courroie crantée. De cette façon, la brosse est mise en rotation.In the recess of the lateral arm, a notched drive axis mounted on a metal axis is placed which receives the notched belt. In this way, the brush is rotated.
Le dispositif se termine par une portion sphérique qui permet de tenir l'outil bien en mains.The device ends with a spherical portion which makes it possible to hold the tool well in hands.
La partie importante de l'invention réside donc dans la brosse tournante dont la vitesse de rotation et la hauteur d'application peuvent être réglées selon les besoins et la nature du matériau à traiter. La brosse est destinée à s'appliquer sur le matériau à traiter et le capot, placé à proximité juste devant, présente une forme qui évite les projections de copeau:,: ou de particules de sciure et garantit à son utilisateur une absence de risque lors de l'utilisation.The important part of the invention therefore resides in the rotating brush, the speed of rotation and the height of application can be adjusted according to the needs and the nature of the material to be treated. The brush is intended to be applied to the material to be treated and the cover, placed close to the front, has a shape which avoids chip splashes:,: or sawdust particles and guarantees its user that there is no risk during use.
L'entraînement de l'axe moteur et de la brosse qui lui est reliée se fait par l'intermédiaire d'une courroie crantée qui assure une bonne adhérence aux deux axes et une marche sans à coup.The drive of the motor axis and of the brush which is connected to it is done by means of a toothed belt which ensures good adhesion to the two axes and smooth running.
La brosse métallique déborde légèrement le carter dans lequel elle est fixée et l'espace qui constitue ce débordement, constitue la hauteur d'attaque de ladite brosse. Ainsi, est-il possible soit d'attaquer très légèrement le bois en réglant la hauteur de la brosse de façon à ce qu'elle ne dépasse en- dessous du carter de protection que de quelques millimètres. Au contraire, s'il est possible de prévoir un polissage ou un décapage plus en profondeur, il convient de laisser dépasser la brosse d'une hauteur plus grande et alors, la surface d'attaque sera sensiblement plus importante. A l'arrêt, il est souhaitable de relever la brosse pour éviter toute manoeuvre risquée et inutile, et pour pouvoir poser le dispositif.The wire brush slightly overflows the casing in which it is fixed and the space which constitutes this overflow constitutes the attack height of said brush. Thus, is it possible either to attack the wood very slightly by adjusting the height of the brush so that it only protrudes below the protective casing by a few millimeters. On the contrary, if it is possible to provide for a deeper polishing or stripping, it is advisable to allow the brush to protrude by a greater height and then, the attack surface will be significantly greater. When stopped, it is desirable to raise the brush to avoid any risky and unnecessary operation, and to be able to install the device.
Les brosses métalliques, destinées à assurer le ponçage ou le décapage du bois, peuvent s'user ou se « graisser » à la longue. Le carter de protection présente, à cet effet, une trappe qui permet de changer aisément la brosse. Cette trappe, lorsqu'elle est refermée, contribue à la rigidité du bâti.Wire brushes, intended for sanding or stripping wood, can wear out or "grease" over time. The protective casing has, for this purpose, a hatch which allows the brush to be easily changed. This hatch, when closed, contributes to the rigidity of the frame.
Enfin, l'extrémité opposée du bâti présente une protubérance de forme oblongue et plus ou moins saillante selon les modèles. A cette extrémité, il est prévu, si besoin, de pouvoir adapter une poche pour la récupération des particules de poussière.Finally, the opposite end of the frame has a protrusion of oblong shape and more or less protruding according to the models. At this end, provision is made, if necessary, to be able to adapt a pocket for recovering dust particles.
Dans un mode d'exécution préféré de l'invention, figuré à la figure 1, le dispositif comporte un bâti (1) sur lequel est fixé l'axe moteur (2) et l'axe d'entraînement (3) de la brosse, reliés entre eux par une courroie crantée (4) , un carter de protection pour la courroie crantée, un capot de sécurité (6) fixé sur la partie arrondie (5) à l'avant du bâti et uneIn a preferred embodiment of the invention, shown in Figure 1, the device comprises a frame (1) on which is fixed the motor axis (2) and the drive axis (3) of the brush , linked together by a toothed belt (4), a protective casing for the toothed belt, a safety cover (6) fixed on the rounded part (5) at the front of the frame and a
FEUILLE DE REMPLACEMENT{REGLE26) molette de réglage (7) en profondeur, pénétrant à travers le carter et abaissant ou relevant le bras qui porte la brosse (8) . Le carter (9) entourant la brosse métallique présente une section circulaire. Le capot de protection est démontable mais il est fixé pendant le fonctionnement.SUBSTITUTE SHEET {RULE26) adjustment wheel (7) in depth, penetrating through the casing and lowering or raising the arm which carries the brush (8). The casing (9) surrounding the wire brush has a circular section. The protective cover is removable, but it is fixed during operation.
Le capot frontal de protection laisse, entre la brosse et lui- même, un espace étroit qui assure le rejet et la déflexion des particules arrachées. Dans ce mode d'exécution particulier, le moyen de préhension est du type poignée de forme triangulaire (10) .The protective front cover leaves, between the brush and itself, a narrow space which ensures the rejection and deflection of the torn particles. In this particular embodiment, the gripping means is of the triangular shaped handle type (10).
La brosse déborde du bâti de 3 mm. Cette hauteur peut être ajustée pour pouvoir épouser les détails de sculpture.The brush protrudes from the frame by 3 mm. This height can be adjusted to match the sculpture details.
Le fond du bâti est formé d'un patin, rainure ou lisse, comportant éventuellement des baguettes de Nylon ou de Téflon qui assurent ainsi un glissement facile sur la surface à traiter.The bottom of the frame is formed by a skid, groove or smooth, optionally comprising strips of Nylon or Teflon which thus ensure easy sliding on the surface to be treated.
La brosse est de forme cylindrique mais sa surface peut être bombée ou présenter des aspérités. La vitesse de rotation du moteur peut être réglée d'une vitesse très lente à une vitesse très élevée. Les roulements à aiguilles de deux axes moteurs permettent une vitesse élevée qui peut aller jusqu'à 30 000 t/mn. La vitesse du moteur est contrôlée par un potentiomètre ou tout autre dispositif de réglage usuel qui permet de varier la vitesse (par exemple de 500 à 5000 t/min environ) .The brush is cylindrical in shape but its surface can be curved or have roughness. The engine speed can be adjusted from a very slow speed to a very high speed. The needle bearings of two motor axes allow a high speed which can go up to 30,000 rpm. The speed of the motor is controlled by a potentiometer or any other usual adjustment device which makes it possible to vary the speed (for example from 500 to 5000 rpm approximately).
La brosse comporte des poils ou des fibres montés par sertissage ou par enroulement autour de l'axe. La brosse est montée sur un manchon porté par l'axe moteur et permet ainsi le démontage rapide de la brosse en cas d'usure ou de changement de matériau, à décaper.The brush has bristles or fibers mounted by crimping or by winding around the axis. The brush is mounted on a sleeve carried by the motor axis and thus allows rapid removal of the brush in the event of wear or change of material, to be stripped.
La figure 2 montre une vue de profil du dispositif avec plus de détails, le dispositif d'entraînement avec les deux axes moteurs (2) et (3) , le carter de protection (9) et son bec de sécurité (14) et la courroie de transmission (4) . Le moyen de préhension est une tige longitudinale renflée à son extrémité et recevant, à l'autre extrémité, l'alimentation électrique. On a figuré sous cette tige, le bouton marche/arrêt (11) du dispositif et le moyen de blocage du dispositif d'arrêt et de marche du moteur (12) . Le moyen de préhension (10) est formé d'une tige allongée, terminée par un corps sphérique (13) .Figure 2 shows a side view of the device in more detail, the drive device with the two motor axes (2) and (3), the protective casing (9) and its spout. safety (14) and the transmission belt (4). The gripping means is a longitudinal rod swollen at its end and receiving, at the other end, the power supply. Under this rod, the on / off button (11) of the device and the locking means of the engine stop and start device (12) have been shown. The gripping means (10) is formed by an elongated rod, terminated by a spherical body (13).

La plaque métallique de cette trappe, une fois refermée, contribue à la solidité et à la rigidité de l'ensemble.Figure 4 is a side view showing the gripping member (10) mounted on the frame (l). The dismantling hatch (15) is closed and is secured by a number of threaded rods (16) on the frame and allows the lower part of the brush (8) to be seen. On the gripping member, there has been shown the power supply and the control button (il). The metal plate of this hatch, once closed, contributes to the solidity and rigidity of the whole.
La figure 5 est une vue par en-dessus du dispositif de préhension (10) . On y voit figuré un dispositif de réglage (17) assurant par déplacement une vitesse de rotation plus ou moins importante. On peut ainsi régler, à tout moment, la vitesse de l'axe de la brosse. On a figuré également le bras latéral d'entraînement (18) assurant le réglage de la brosse, vu en coupe.Figure 5 is a view from above of the gripping device (10). There is shown an adjustment device (17) ensuring by displacement a more or less high speed of rotation. It is thus possible to adjust, at any time, the speed of the axis of the brush.
