Abstract

The invention relates to a machine for stirring paints. This machine is of the type comprising support racks (3) of cans of tints provided with an upper stirrer lid (5), and a mechanism for driving the stirrer lids on each of the racks, the stirrer lids (5) each being provided with a motion take-up pinion (27) for the stirrer shaft inside the cans. It is characterized in that said mechanism for driving the stirrer lids brings into play a set of endless screws (29) mounted one on each of the racks, these screws each coming to mesh with the driving pinions (27) of the stirrer lids of a same rack and being driven at an adequate speed of rotation, which is variable depending on the range of the cans of tints of the racks.

Description

La présente invention concerne une machine d'agitation pour peintures, du type comportant des étagères supports de boîtes de teintes munies d'un couvercle agitateur supérieur, et un mécanisme d'entraînement des couvercles agitateurs sur chacune des étagères, les couvercles agitateurs étant pourvus chacun d'un pignon de prise de mouvement pour l'axe agitateur au sein des boîtes.The present invention relates to a stirring machine for paints, of the type comprising shelves supporting color boxes provided with an upper agitator cover, and a mechanism for driving the agitator covers on each of the shelves, the agitator covers being each provided a power take-off pinion for the agitator axis within the boxes.

L'invention concerne en particulier un perfectionnement de la transmission de mouvement aux couvercles agitateurs.The invention relates in particular to an improvement in the transmission of movement to the agitator covers.

Sur les machines d'agitation de ce type connues, l'entraînement des couvercles agitateurs est essentiellement effectué au moyen d'une transmission à chaînes, une sur chaque étagère engrenant extérieurement sur sa longueur avec les pignons d'entraînement des couvercles positionnés. Les chaînes d'entraînement des étagères sont entraînées elles-même par des pignons à partir d'un arbre vertical principal monté latéralement sur la hauteur de la machine et actionné par un motoréducteur inférieur.On stirring machines of this known type, the drive of the agitator covers is essentially carried out by means of a chain transmission, one on each shelf externally meshing along its length with the drive sprockets of the covers positioned. The drive chains of the shelves are themselves driven by pinions from a main vertical shaft mounted laterally on the height of the machine and actuated by a lower gear motor.

Ce type de transmission de mouvement ne se prête pas facilement à un changement de configuration des étagères de la machine.This type of motion transmission does not easily lend itself to a change in configuration of the machine shelves.

L'invention vise à remédier à ces inconvénients et propose une machine d'agitation pour peintures, du type comportant des étagères supports de boîtes de teintes munies d'un couvercle agitateur supérieur, et un mécanisme d'entraînement des couvercles agitateurs sur chacune des étagères, les couvercles agitateurs étant pourvus chacun d'un pignon de prise de mouvement pour l'axe agitateur au sein des boîtes, caractérisée en ce que ledit mécanisme d'entraînement des couvercles agitateurs fait intervenir un ensemble de vis sans fin montées à l'unité sur chacune des étagères, ces vis venant en prise chacune avec les pignons d'entraînement des couvercles agitateurs d'une même étagère et étant animées à un régime de rotation adéquat, variable selon la gamme des boîtes de teintes des étagères.The invention aims to remedy these drawbacks and proposes a stirring machine for paints, of the type comprising shelves supporting color boxes provided with an upper agitator cover, and a mechanism for driving the agitator lids on each of the shelves. , the agitator covers each being provided with a power take-off pinion for the agitator axis within the boxes, characterized in that said agitator cover drive mechanism involves a set of endless screws mounted individually on each of the shelves, these screws each engaging with the drive pinions of the agitator covers of the same shelf and being driven at a rotation speed suitable, variable depending on the range of color boxes on the shelves.

L'entraînement des vis (qui nécessite un faible couple de rotation) est effectué avantageusement au moyen d'une transmission par courroies menantes et de préférence crantées (pour assurer une transmission de vitesse rigoureuse) et poulies menées solidaires des vis ou encore à chaînes et pignons en bout de vis, sur l'un des côtés de la machine.The driving of the screws (which requires a low torque) is advantageously carried out by means of a transmission by driving and preferably toothed belts (to ensure rigorous speed transmission) and driven pulleys integral with the screws or even with chains and pinions at the end of the screw, on one side of the machine.

Une série de courroies ou chaînes permet la reprise du mouvement d'une étagère à la suivante.A series of belts or chains allows the resumption of movement from one shelf to the next.

Il résulte de cette disposition que l'on peut utiliser pour l'entraînement de la machine un simple moteur électrique de type asynchrone sans avoir besoin d'un renvoi réducteur de vitesse, la réduction principale étant réalisée par les vis sans fin. Cette réduction est suffisante pour assurer un régime de rotation convenable des axes agitateurs des couvercles.It follows from this arrangement that one can use for driving the machine a simple asynchronous electric motor without the need for a speed reduction gear, the main reduction being achieved by the worms. This reduction is sufficient to ensure a suitable rotation speed of the agitator shafts of the covers.

Le moteur peut ainsi être disposé horizontalement avec sa poulie motrice (ou un pignon) en prise directe avec la ou les courroies ou chaînes d'entraînement. Dans ces conditions, une implantation horizontale basse du moteur ne gêne pas le positionnement des boîtes sur l'étagère inférieure, qui demeure par conséquent totalement disponible.The motor can thus be arranged horizontally with its drive pulley (or a pinion) in direct engagement with the belt or belts or drive chains. Under these conditions, a low horizontal positioning of the motor does not hinder the positioning of the boxes on the lower shelf, which therefore remains fully available.

Naturellement, ce type de transmission de mouvement convient à des machines d'agitation recevant des couvercles agitateurs avec leur boîtes positionnés en suspension sur les étagères, ou même avec clipsage de positionnement des boîtes posées sur les étagères.Naturally, this type of movement transmission is suitable for stirring machines receiving agitator covers with their boxes positioned in suspension on the shelves, or even with positioning clipping of the boxes placed on the shelves.

Other characteristics and advantages of the invention will appear below with regard to the description of an exemplary embodiment and with reference to the appended drawings, in which:
  • Figure 1 is a schematic elevational view of a stirring machine for paints according to the invention;
  • Figure 2 is a perspective view of this machine, but with side belt drive;

  • Figure 7 is a section similar to Figure 4 showing the drive of the agitator covers by a spring screw.

Comme représenté sur les figures 1 et 2, la machine d'agitation selon l'invention est essentiellement constituée de deux montants latéraux 1, auxquels sont attachées horizontalement des étagères 3 supports des couvercles agitateurs 5 des boîtes de teinte 7, et d'un moteur électrique d'entraînement 9 au niveau inférieur. Les boîtes de teinte 7 sont fixées aux couvercles, eux-mêmes suspendus à l'étagère de façon classique par des pattes transversales 11.As shown in FIGS. 1 and 2, the stirring machine according to the invention essentially consists of two lateral uprights 1, to which are horizontally attached shelves 3 supports for the agitator lids 5 of the shade boxes 7, and a motor electric drive 9 at the lower level. The shade boxes 7 are fixed to the covers, themselves suspended from the shelf in a conventional manner by transverse tabs 11.

Les étagères sont accrochées aux montants par l'intermédiaire de crochets 13 à leurs extrémités, engagés dans des perforations correspondantes 15 formées à intervalles réguliers sur la longueur des montants. Elles peuvent par conséquent être disposées avec écartement et hauteur variables selon la configuration de charge de la machine souhaitée, et en fonction du dimensionnement des boîtes de teinte.The shelves are hung on the uprights by means of hooks 13 at their ends, engaged in corresponding perforations 15 formed at regular intervals along the length of the uprights. They can therefore be arranged with variable spacing and height depending on the load configuration of the desired machine, and depending on the size of the color boxes.

L'un des montants loge une partie du système d'entraînement 17 des couvercles agitateurs des boîtes de teintes sur les étagères. Ce système d'entraînement est protégé par un carter longitudinal 19 (figure 4), monté articulé latéralement sur le montant et sur sa hauteur.One of the uprights houses part of the drive system 17 of the agitator covers of the color boxes on the shelves. This drive system is protected by a longitudinal casing 19 (FIG. 4), mounted articulated laterally on the upright and on its height.

La machine est légèrement inclinée vers l'arrière, étant en appui sur deux jambes arrière 21 repliables et dont l'écartement est limité par un compas 23 bloqué à l'ouverture. Une croix de rigidification 25 peut être fixée sur les jambes d'appui arrière ou de préférence sur les montants verticaux. Cette disposition avec accrochage des étagères sur les montants et appui sur des jambes repliables arrière permet un montage rapide et sans outil de la machine. Naturellement, la machine peut encore être réalisée dans une version verticale sur un pied d'appui avant et arrière. Néanmoins, la version inclinée améliore la stabilité de la machine et confère un bon accès aux couvercles agitateurs. Par ailleurs, la peinture résiduelle (quelques gouttes) des becs de couvercles agitateurs, après usage, ne tombe pas sur les étagères sous-jacentes mais peut être recueillie au sol.The machine is slightly inclined towards the rear, being supported on two rear legs 21 which are foldable and whose spacing is limited by a compass 23 blocked at the opening. A stiffening cross 25 can be fixed on the rear support legs or preferably on the vertical uprights. This arrangement with hooking of the shelves on the uprights and support on the rear folding legs allows rapid and tool-free assembly of the machine. Naturally, the machine can also be produced in a vertical version on a front and rear support leg. However, the inclined version improves the stability of the machine and gives good access to the agitator covers. In addition, the residual paint (a few drops) from the spouts of the agitator lids, after use, does not fall on the underlying shelves but can be collected on the floor.

Comme représenté sur les figures 3 et 4, les couvercles agitateurs avec leurs pignons d'entraînement 27 sont entraînés au moyen de vis sans fin 29, implantées à l'unité sur chacune des étagères. Ces vis sont entraînées en rotation au moyen de la transmission latérale sur montant animée par le moteur inférieur 9. Les vis sont implantées à l'intérieur d'un fourreau 31 muni d'une ou plusieurs fentes longitudinales 33 à l'avant. Cette fente permet la mise en contact des dents des pignons des couvercles, lors de leur mise en place, avec le filet de la vis. Les vis sont montées tourillonnantes par des paliers d'extrémité sur les montants latéraux. Ces paliers à roulement à billes 35 supportent les poulies d'entraînement 37 des vis à leur extrémité, à l'intérieur du montant. Ils sont en outre solidaires chacun d'une platine 41. Ces platines sont reliées à un profil 39 support des pattes 11, et elles sont munies de deux crochets 13 (précités) pour l'accrochage de l'étagère aux montants, par les perforations 15 des montants.As shown in FIGS. 3 and 4, the agitator covers with their drive pinions 27 are driven by means of endless screws 29, installed individually on each of the shelves. These screws are rotated by means of the lateral transmission on the upright driven by the lower motor 9. The screws are located inside a sheath 31 provided with one or more longitudinal slots 33 at the front. This slot allows the teeth of the pinions of the covers to come into contact with the thread of the screw when they are put in place. The screws are journalled by end bearings on the side uprights. These ball bearing bearings 35 support the drive pulleys 37 of the screws at their end, inside the upright. They are also each secured to a plate 41. These plates are connected to a profile 39 supporting the legs 11, and they are provided with two hooks 13 (aforementioned) for the attachment of the shelf to the uprights, by the perforations. 15 amounts.

Les vis sans fin peuvent être constituées d'éléments courts 47 en matière plastique injectée, d'environ 300 mm de longueur. Ces éléments sont raccordés l'un à l'autre avec parfaite coïncidence des filets pour s'adapter à la longueur de vis souhaitée, usuellement de un à trois mètres, selon la largeur de la machine. Ces éléments de vis comportent une extrémité mâle 49 fendue munie de deux parties hélicoïdales externes 51 au même pas que la vis. Ces parties viennent à l'assemblage des éléments s'engager élastiquement et en verrouillage dans un évidement complémentaire 53 d'une partie femelle 55 correspondante. Sur la figure 6, on voit que l'entraînement en rotation des éléments se fait par les plats opposés 57 des extrémités.The worms can be made up of short elements 47 of injected plastic, about 300 mm in length. These elements are connected to each other with perfect coincidence of the threads to adapt to the desired screw length, usually from one to three meters, depending on the width of the machine. These screw elements have a split male end 49 provided with two external helical parts 51 at the same pitch as the screw. These parts come to the assembly of the elements engaging elastically and locking in a complementary recess 53 of a corresponding female part 55. In FIG. 6, it can be seen that the elements are driven in rotation by the opposite flats 57 of the ends.

Dans le mode de réalisation de la figure 3, les poulies d'entraînement 37 menées sont de type crantée double. Elles reçoivent deux courroies crantées (59, 59'), l'une recevant le mouvement de l'étagère inférieure, chacune des courroies étant maintenue en place au moyen d'un galet tendeur 61 comme représenté à la figure 3. L'entraînement est effectué en liaison directe depuis la poulie du moteur, lequel est de type électrique asynchrone. Une réduction de vitesse peut être réalisée par le jeu des diamètres de poulie du moteur, par exemple selon la fréquence d'alimentation, qui peut varier de 50 à 60 HZ selon les pays, et de telle manière que le régime de rotation convenable des axes d'agitateurs des couvercles soit maintenu.In the embodiment of FIG. 3, the driven drive pulleys 37 are of the double toothed type. They receive two notched belts (59, 59 '), one receiving the movement of the lower shelf, each of the belts being held in place by means of a tension roller 61 as shown in FIG. 3. The drive is performed in direct connection from the motor pulley, which is of the asynchronous electric type. A speed reduction can be achieved by the play of the pulley diameters of the motor, for example according to the feeding frequency, which can vary from 50 to 60 HZ depending on the country, and in such a way that the proper rotation speed of the axes of the agitators of the covers is maintained.

Comme représenté sur la figure 7, les vis sans fin peuvent consister en des ressorts à boudin 63 réalisés en fil d'acier d'un diamètre suffisant pour assurer une bonne rigidité axiale. Les pignons des couvercles agitateurs sont conformés pour fonctionner avec une telle vis ressort. Il est par ailleurs rappelé que le nombre de dents de pignons peut varier, ceci pour s'adapter au régime d'agitation souhaité. Cette vis ressort tourne dans sa fourrure environnante, laquelle est en matière plastique pour éviter le bruit. L'entraînement est réalisé au moyen d'un embout d'extrémité 65 monté sur le palier et épousant la forme du ressort dans lequel il se visse par l'intérieur. Le sens de rotation est naturellement prévu pour que le ressort reste toujours en appui serré sur cette pièce d'embout.As shown in Figure 7, the worms may consist of coil springs 63 made of steel wire of a diameter sufficient to ensure good axial rigidity. The sprockets of the agitator covers are designed to operate with such a spring screw. It is also recalled that the number of pinion teeth can vary, this to adapt to the desired stirring regime. This spring screw turns in its surrounding fur, which is made of plastic to avoid noise. The drive is carried out by means of an end piece 65 mounted on the bearing and taking the shape of the spring into which it is screwed from the inside. The direction of rotation is naturally provided so that the spring always remains in tight support on this end piece.

On notera que l'on peut envisager d'autres formes de vis que celles décrites et, par exemple, issues d'extrusion rotative avec coupe à longueur ou simplement de soudage sur un tube d'un jonc ayant la forme du filet de vis.Note that one can consider other screw shapes than those described and, for example, from rotary extrusion with cut to length or simply welding on a tube of a rod having the shape of the screw thread.

Ce qui précéde démontre bien la facilité de mise à configuration souhaitée de la machine grâce à cette nouvelle conception de la transmission du mouvement, qui permet d'installer les étagères à la hauteur et à écartement souhaités, grâce à l'accrochage rapide des crochets d'attaches sur les perforations des montants et, éventuellement, de modifier la configuration de la machine (nombre d'étagères respectivement pour petites et pour grandes boîtes), et d'ajouter des étagères supplémentaires. La manoeuvre est donc simple et rapide et permet l'utilisation optimale de l'énergie motrice.The above clearly demonstrates the ease of setting up the desired configuration of the machine thanks to this new design of the transmission of movement, which makes it possible to install the shelves at the desired height and spacing, thanks to the rapid hooking of the hooks d 'fasteners on the perforations of the uprights and, possibly, to modify the configuration of the machine (number of shelves respectively for small and for large boxes), and to add additional shelves. The maneuver is therefore simple and quick and allows the optimal use of motive energy.
