Description

L'invention concerne un couvercle agitateur pour boíte de teinte sur les machines d'agitation de peinture et en particulier un couvercle agitateur pourvu d'un dispositif évitant l'usure de contact des agitateurs sur le fond des boítes pendant l'agitation.The invention relates to an agitator cover for a can. color on paint stirring machines and particular an agitator cover provided with a device avoiding contact wear of the agitators on the bottom of the boxes during agitation.

On sait que l'effet hydrodynamique de brassage de l'agitateur au sein de la laque conduit à appliquer l'axe agitateur vers le bas et avec une force relativement importante, ce qui dans le cas d'un montage libre en translation de l'axe agitateur relativement au couvercle d'entraínement supérieur, amène l'extrémité de l'axe agitateur à venir en contact de frottement sur le fond de boíte avec une érosion rapide de celui-ci. Ce fond de boíte est en effet relativement mince, d'épaisseur égale à environ 0,2 mm et par ailleurs, les particules érodées du fond peuvent polluer la laque traitée.We know that the hydrodynamic mixing effect of the agitator within the lacquer leads to applying the axis agitator down and with relatively force important, which in the case of free mounting in translation of the agitator axis relative to the cover upper drive, brings the end of the axis agitator coming into frictional contact on the bottom of box with rapid erosion of it. This bottom of the box is indeed relatively thin, of thickness equal to approximately 0.2 mm and also eroded particles from the bottom can pollute the lacquer treated.

L'invention vise à remédier à cet inconvénient et propose un couvercle agitateur pour boíte de teinte sur les machines d'agitation de peinture, de type comprenant un axe agitateur monté libre en translation relativement au couvercle, pourvu d'une tige axiale entraínée en rotation et d'une pale d'agitation inférieure, l'axe agitateur étant apte à s'appliquer en butée sur le fond de boíte sous la poussée de la pale en cours d'agitation, caractérisé en ce que l'axe agitateur comporte à son extrémité inférieure un embout d'application sur le fond de boíte, cet embout étant monté libre en rotation sur l'axe agitateur et étant pourvu d'au moins trois éléments en saillie inférieurs aptes à venir en contact par un même plan perpendiculaire à l'axe avec la surface de fond de la boíte.The invention aims to remedy this drawback and offers an agitator cover for a shade box on the paint stirring machines, of the type comprising an axis agitator mounted free in translation relative to the cover, provided with an axial rod driven in rotation and a lower stirring blade, the stirring axis being able to be applied in abutment on the bottom of the box under the blade thrust during agitation, characterized in that the agitator axis has at its lower end a application tip on the bottom of the box, this tip being freely rotatably mounted on the agitator axis and being provided at least three lower projecting elements capable of come into contact by the same plane perpendicular to the axis with the bottom surface of the box.

Naturellement, lesdits trois éléments en saillie de l'embout ont leur extrémité inférieure toutes trois disposées dans un même plan, sensiblement parallèle à celui du fond de boíte et le périmètre du triangle ainsi défini contient l'axe. Ces éléments en saillie viennent en contact ponctuel avec le fond de boíte.Naturally, said three projecting elements of the tip have their bottom end all three arranged in the same plane, substantially parallel to that the bottom of the box and the perimeter of the triangle thus defined contains the axis. These protruding elements come into contact punctual with the bottom of the box.

L'embout est de préférence monté libre en rotation coaxialement à l'axe agitateur, bien qu'une légère excentration à l'intérieur des trois points d'appui soit concevable.The nozzle is preferably mounted free to rotate coaxial to the agitator axis, although a slight eccentricity inside the three support points either conceivable.

Il résulte de cette disposition que, en cours d'agitation, l'axe agitateur vient s'appliquer sur le fond de la boíte par son embout qui demeure fixe sur le fond grâce à l'adhérence de l'appui ponctuel des éléments en saillie, l'axe agitateur tournant sur l'embout. De cette façon, le fond de boíte n'est pas érodé par l'axe agitateur.It follows from this provision that, in progress agitation, the agitator axis is applied to the bottom of the box by its tip which remains fixed on the bottom thanks to the adhesion of the point support of the elements in projection, the agitator axis rotating on the nozzle. Of this way, the bottom of the box is not eroded by the agitator axis.

Ledit embout est avantageusement pourvu d'un dimensionnement en hauteur déterminé en relation avec la pale, de façon à amener cette dernière à une hauteur déterminée optimale de fonctionnement relativement à la surface de fond de la boíte.Said tip is advantageously provided with a height design determined in relation to the pale, so as to bring the latter to a height determined optimal functioning relative to the bottom surface of the box.

Par ailleurs, l'embout avec ses trois points donne une assise inférieure stable à l'axe de rotation.In addition, the tip with its three points gives a lower seat stable to the axis of rotation.

Ledit embout d'axe agitateur est avantageusement une platine circulaire de diamètre légèrement supérieur à équivalent à celui de la tige d'axe agitateur (4-15 mm), montée perpendiculairement à l'axe de rotation. Les éléments en saillie sont des doigts cylindriques dont l'extrémité est arrondie. Ces doigts sont disposés de façon circulaire à 120° l'un de l'autre.Said agitator shaft end piece is advantageously a circular plate slightly larger in diameter equivalent to that of the agitator shaft rod (4-15 mm), mounted perpendicular to the axis of rotation. The elements protruding are cylindrical fingers whose end is rounded. These fingers are arranged circularly to 120 ° from each other.

Le montage rotatif coaxial de l'embout sur l'axe agitateur est assuré par un dispositif d'encliquetage de conformation circulaire à prise dans l'alésage de fût d'extrémité de l'axe agitateur.Coaxial rotary mounting of the nozzle on the axis agitator is provided by a latching device circular conformation to be taken in the barrel bore end of the agitator axis.

Ce dispositif d'encliquetage peut être constitué par trois pattes de clip supérieures fixées dans la partie centrale supérieure de l'embout et dont la partie de nez supérieure coopère avec une jupe complémentaire du fût d'axe. Cette partie de montage rotative de l'embout est de préférence en matière synthétique à faible coefficient de friction, par exemple à base de "Téflon".This latching device can be constituted by three upper clip tabs fixed in the part upper central tip and the nose part upper cooperates with a complementary skirt of the barrel axis. This rotating mounting part of the nozzle is preferably synthetic material with a low coefficient of friction, for example based on "Teflon".

L'axe agitateur est de préférence pourvu d'une pale à configuration spirale (génératrice de forme spirale). L'embout avec ses trois points selon l'invention permet d'amener cette pale spirale de haute efficacité à une hauteur de référence précise relativement à la surface de fond de la boíte, à laquelle sa performance est optimale, à un niveau élevé auquel le montage en vibration de la pale n'est plus nécessaire.The agitator axis is preferably provided with a paddle spiral configuration (spiral generator). The tip with its three points according to the invention allows to bring this high efficiency spiral blade to a precise reference height relative to the surface of bottom of the box, at which its performance is optimal, at a high level at which the vibration mounting of the blade is no longer required.

Cette pale spirale peut être montée mobile en translation sur la tige d'axe agitateur, à sa partie inférieure, et l'embout être monté rotatif sur la pale à sa partie inférieure, coaxialement à cette dernière, dépassant de son bord d'attaque inférieur d'une hauteur déterminée correspondant à la hauteur d'application de la pale sur le fond de boíte où le fonctionnement est optimal.This spiral blade can be mounted mobile by translation on the agitator shaft rod, at its part lower, and the nozzle be rotatably mounted on the blade at its lower part, coaxial to the latter, protruding of its lower leading edge of a determined height corresponding to the height of application of the blade on the bottom of the box where the operation is optimal.

Une forme de réalisation de l'invention est à présent décrite en référence aux dessins annexés, sur lesquels :

  • la figure 1 est une vue d'un couvercle agitateur avec sa boíte selon l'invention montrant par un arrachement le montage de l'embout d'appui de l'agitateur,
  • la figure 2 est une vue en coupe axiale agrandie de l'embout d'appui de ce couvercle agitateur, et
  • la figure 3 est une vue de dessous de l'embout d'appui du couvercle agitateur.
An embodiment of the invention is now described with reference to the accompanying drawings, in which:
  • FIG. 1 is a view of an agitator cover with its box according to the invention showing, with a cutaway, the mounting of the bearing end piece of the agitator,
  • FIG. 2 is an enlarged axial section view of the bearing end piece of this agitator cover, and
  • Figure 3 is a bottom view of the end cap of the agitator cover.

Avec référence à la figure 1, le couvercle agitateur 1 représenté est d'un modèle classique (excepté l'agitateur), comportant un bec verseur 3, une poignée de manipulation 5 à l'extrémité diamétralement opposée au bec, et un axe agitateur 7 en position axiale verticale. L'axe est entraíné par un pignon supérieur 9, lui-même en prise avec une chaíne continue (non représentée) d'une machine d'agitation sur laquelle le couvercle est monté. Ce couvercle reçoit une boíte de teinte inférieure 11.With reference to Figure 1, the agitator cover 1 represented is of a classic model (except the agitator), comprising a pouring spout 3, a handling handle 5 to the end diametrically opposite the spout, and an axis agitator 7 in vertical axial position. The axis is driven by an upper pinion 9, itself engaged with a chain continuous (not shown) of a stirring machine on which the cover is mounted. This cover receives a lower shade 11.

L'axe agitateur 7 est constitué d'une tige axiale 13 et d'une pale agitatrice inférieure 15. La pale 15 est montée mobile en translation sur la tige d'axe 13 à sa partie inférieure de façon à descendre sous l'action hydrodynamique d'agitation vers le fond 17 de la boíte (surface plane horizontale) à faible distance de celui-ci.The agitator axis 7 consists of an axial rod 13 and a lower agitating blade 15. The blade 15 is mounted movable in translation on the axis rod 13 in its part lower so as to descend under the hydrodynamic action agitation towards the bottom 17 of the box (flat surface horizontal) at a short distance from it.

On notera que la tige 13 a une longueur déterminée constante, permise grâce au montage en translation de la pale et adaptée à l'utilisation aux diverses boítes dans une gamme de contenance donnée, la hauteur de celles-ci variant légèrement d'un constructeur à l'autre.It will be noted that the rod 13 has a determined length constant, allowed thanks to the mounting in translation of the pale and suitable for use with various boxes in a given capacity range, the height of these varying slightly from one manufacturer to another.

La pale 15 est de type à génératrice 19 à forme de spirale dont l'efficacité de brassage permet l'utilisation sans avoir à faire vibrer l'axe agitateur 7, ce qui nécessitait dans l'état de la technique connu un montage en suspension de la pale avec l'adaptation correspondante en hauteur à chaque boíte.The blade 15 is of the generator type 19 in the form of spiral whose mixing efficiency allows the use without having to vibrate the agitator axis 7, which required in the prior art known a mounting in blade suspension with corresponding adaptation in height to each box.

La pale 15 est montée coulissante longitudinalement par son fût central 21 sur l'axe agitateur, ceci sur une course déterminée. Ce fût 21 comporte deux épaulements longitudinaux 23 diamétralement opposés pourvus chacun d'une rainure interne 25 recevant une nervure complémentaire 27 de la tige. La translation vers le haut est limitée par une butée supérieure 29 à l'extrémité haute de chacune des rainures, et de même vers le bas par une mise en butée inférieure.The blade 15 is slidably mounted longitudinally by its central shaft 21 on the agitator axis, this on a stroke determined. This bole 21 has two shoulders longitudinal 23 diametrically opposite each provided with a internal groove 25 receiving a complementary rib 27 of the stem. Upward translation is limited by a upper stop 29 at the upper end of each of the grooves, and similarly down by a stop lower.

La pale 15 comporte en outre à l'extrémité inférieure de son fût axial 21 un embout d'appui inférieur 31 monté libre en rotation sur celui-ci et qui fait saillie vers le bas sous le bord rectiligne inférieur horizontal 33 de la pale. La distance h entre le plan inférieur horizontal de l'embout et le bord inférieur 33 de la pale est déterminée selon cette dernière et la peinture à traiter (dans une moindre mesure) de manière à obtenir une agitation d'efficacité optimale.The blade 15 further comprises at the lower end of its axial shaft 21 a lower bearing end piece 31 mounted freely rotating on it and which projects down under the horizontal lower rectilinear edge 33 of the blade. The distance h between the lower horizontal plane of the nozzle and the lower edge 33 of the blade is determined according to the latter and the paint to be treated (in a lesser measurement) so as to obtain an efficiency agitation optimal.

L'embout 31 comporte (figure 2 et 3) une partie de corps à forme de disque ou platine circulaire 35, de diamètre équivalent à celui du fût de la pale 21, trois éléments à crochet d'encliquetage supérieurs 37 (pattes de clip) sur un même cercle à 120° d'angle l'un de l'autre, disposés verticalement sur la partie centrale de la platine 35, et trois doigts inférieurs 39 disposés verticalement sous la platine 35 et également sur un même cercle à 120° d'angle l'un de l'autre. L'ensemble possède une symétrie axiale, étant issu de moulage en une matière synthétique à faible coefficient de friction (à base de "Téflon").The end piece 31 comprises (FIGS. 2 and 3) a body part disc-shaped or circular plate 35, diameter equivalent to that of the barrel of the blade 21, three elements to upper snap hook 37 (clip tabs) on a same circle at 120 ° from each other, arranged vertically on the central part of the plate 35, and three lower fingers 39 arranged vertically under the plate 35 and also on the same circle at 120 ° angle one of the other. The whole has an axial symmetry, from molding in a low synthetic material coefficient of friction (based on "Teflon").

Les doigts 39 ont leur extrémité arrondie et viennent au cours de l'agitation s'appliquer ponctuellement sur la surface de fond 17 de la boíte (dans un plan perpendiculaire à l'axe). Ils sont disposés sensiblement à la périphérie de la platine 35, étant maintenus rigidement à celle-ci par des nervures radiales 41. leur disposition latérale augmente le couple de liaison adhérente au fond de la boíte, contre tout glissement rotatif sur ce fond.The fingers 39 have their rounded end and come to the during the agitation apply occasionally on the bottom surface 17 of the box (in a perpendicular plane to the axis). They are arranged substantially on the periphery of the plate 35, being rigidly held thereon by radial ribs 41. their lateral arrangement increases the bonding torque adherent to the bottom of the box, against all rotary sliding on this background.

Les éléments de crochet supérieurs 37 constituent la partie de liaison rotative de l'embout sur la pale. Ils ont leur nez de crochetage supérieur 43 tourné radialement vers l'extérieur et viennent s'engager en encliquetage dans la jupe cylindrique 45 interne inférieure complémentaire du fût de pale. Cette jupe 45 est développée verticalement enserrant avec léger jeu les jambes verticales des éléments de crochets 37 dans sa partie inférieure de diamètre réduite 47 et recevant dans une partie sus-jacente de plus grand diamètre les nez 43 de crochets. Ce montage en crochetage de l'embout sur le fût de pale comporte un jeu adapté, d'une part pour le débattement en rotation et, d'autre part, pour le débattement en plan d'assise de l'embout sur la surface de fond 17.The upper hook elements 37 constitute the part of rotary connection of the nozzle on the blade. they have their upper hook nose 43 facing radially towards the exterior and come into engagement by snapping into the cylindrical skirt 45 internal lower complementary to the barrel pale. This skirt 45 is developed vertically enclosing with slight play the vertical legs of the elements hooks 37 in its lower part of reduced diameter 47 and receiving in a larger overlying part diameter of hook noses 43. This hooking assembly of the tip on the blade shaft has a suitable clearance, of a part for the rotation travel and, secondly, for the travel in seat plane of the nozzle on the surface background 17.

Le glissement rotatif relatif de l'embout et de la pale est effectué entre les surfaces horizontales en regard respectivement 49, 49' d'extrémité inférieure de fût de la pale et de la surface supérieure correspondante de la platine. Le couple de glissement est très faible, bien inférieur au couple de glissement des points d'appui des doigts 39 sur la surface de fond 17 de la boíte.The relative rotary sliding of the nozzle and the blade is performed between the facing horizontal surfaces respectively 49, 49 'of the barrel lower end of the blade and the corresponding upper surface of the platinum. The sliding torque is very low, well less than the sliding torque of the support points fingers 39 on the bottom surface 17 of the box.

On notera par ailleurs qu'en raison du montage encliqueté de l'embout, celui-ci peut être déposé facilement, par simple retrait à l'aide d'une lame de tournevis, par exemple pour son remplacement en cas d'usure ou par un embout de hauteur différente selon la peinture traitée.It should also be noted that due to the mounting snap-on end cap, it can be removed easily, by simply removing it using a screwdriver blade, for example to replace it in case of wear or by a nozzle of different height depending on the paint treated.

En outre, comme indiqué précédemment, l'embout peut être monté à titre de variante directement sur la tige d'axe agitateur, à son extrémité inférieure, et non sur la pale, l'axe coulissant de façon télescopique avec une pale fixée sur l'axe ou la pale coulissant en translation sur l'axe.In addition, as indicated above, the tip can be alternatively mounted directly on the axle rod agitator, at its lower end, and not on the blade, the telescopically sliding axis with a fixed blade on the axis or the blade sliding in translation on the axis.
