Elle concerne en particulier une machine d'entraînement de couvercles agitateurs, sur chacun desquels est monté un pot de peinture, les couvercles étant suspendus au moyen de supports à glissières latérales sur des étagères de la machine et entraînés individuellement par un pignon de prise avant engagé sur une vis sans fin en rotation de l'étagère.It relates in particular to an agitator lids driving machine, on each of which is mounted a paint bucket, the lids being suspended by means of lateral slide supports on shelves of the machine and driven individually by a front engagement gear engaged on a worm in rotation of the shelf.

Une machine selon l'état de la technique proche, voir par exemple US-A-5 310 258, comporte deux montants verticaux supports des étagères, dont un montant comporte, enfermé dans un carter, l'ensemble des poulies et courroies d'entraînement des vis sans fin des étagères. Néanmoins, les étagères comportent chacune leur propre palier d'axe de rotation des vis sans fin et qu'il est nécessaire de monter sur le montant correspondant. Le montage des paliers d'étagère nécessite d'une part de fixer le palier sur le montant et d'autre part d'ajuster pour chacun l'accouplement de poulie et courroie d'entraînement correspondant dans le carter du montant. En outre, le montage du motoréducteur d'entraînement à la base du montant nécessite une fixation par des outils et clefs spécifiques. Un tel montage est relativement long et complexe, nécessitant par conséquent une main d'oeuvre spécialisée et un temps de main d'oeuvre important.A machine according to the state of the art, see for example US-A-5 310 258, comprises two uprights vertical supports shelves, including an amount comprises, enclosed in a housing, all pulleys and drive belts worm gear shelves. However, the shelves each have their own bearing axis of rotation of the worm and it is necessary to mount on the corresponding amount. The mounting of the shelf bearings requires, on the one hand, to fix the bearing on the upright and, on the other hand, to adjust for each the pulley coupling and corresponding drive belt in the casing of the upright. In addition, the mounting of the gear motor to the base of the amount requires fixing with tools and specific keys. Such an arrangement is relatively long and complex, requiring therefore a specialized workforce and a significant labor time.

Par ailleurs, on connaît par le document EP-A-0 298 806 un appareil d'agitation sélective des teintes de base de peinture, comprenant un groupe motoréducteur électrique pouvant être adapté à un montant d'une machine d'agitation de peinture à entraînement par chaîne des couvercles agitateurs d'étagère, ce groupe motoréducteur devant être relié aux chaînes d'entraînement d'étagère des couvercles agitateurs.Furthermore, EP-A-0 298 806 discloses an apparatus for selectively agitating paint basecoats, comprising an electric geared motor unit which can be adapted to an amount of a driving paint stirring machine. by chain of shelf stirring lids, this geared motor unit to be connected to the shelf drive chains of the agitator lids.

L'invention vise à remédier à ces inconvénients et propose une machine d'agitation de peinture conforme aux revendications 1 et 14.The invention aims to overcome these disadvantages and proposes a paint stirring machine according to claims 1 and 14.

Lesdits paliers de vis sans fin comportent chacun un arbre taraudé axialement recevant la tige filetée d'axe d'accouplement de vis sans fin, de sorte que le montage de la vis sur le palier soit effectué rapidement et sans autre ajustement par vissage axial de la vis sans fin sur son palier.Said worm bearings each comprise a threaded shaft axially receiving the threaded shaft spindle of worm coupling, so that the mounting of the screw on the bearing is performed quickly and without further adjustment by axial screwing the worm on its bearing.

L'accouplement entre chacune des vis sans fin et le palier de montant correspondant peut être réalisé au moyen d'un joint d'accouplement, par exemple à tampon caoutchouc à prise par deux embouts filetés d'extrémité, respectivement, dans l'arbre taraudé de palier et l'extrémité opposée de vis sans fin, ce joint ayant une fonction de cardan, compensant les éventuels légers défauts d'alignement d'axe, d'amortissement des à coups d'entraînement, et de sécurité à un effort excessif d'entraînement.The coupling between each of the worm and the corresponding upright bearing can be achieved by means of a coupling joint, for example rubber pad with two end threaded ends, respectively, in the threaded shaft. bearing and the opposite end of worm, this seal having a gimbal function, compensating for any slight misalignment of axis, damping of training, and safety to an excessive effort of 'training.

L'invention concerne également le procédé de montage de cette machine d'agitation de teintes de peinture.The invention also relates to the mounting method of this paint color stirring machine.

Le procédé de montage est caractérisé par les étapes successives suivantes :

  • disposer le montant comportant l'ensemble poulies et courroies d'entraînement des étagères sur le motoréducteur de façon à accoupler la courroie d'entraînement de l'ensemble poulies et courroies du montant à la poulie d'entraînement du motoréducteur,
  • réaliser l'assemblage final du motoréducteur sur le montant,
  • relier les deux montants support d'étagères en station verticale au moyen de deux barres arrières articulées en croisillon et fixées par leur extrémité à chacun des montants,
  • implanter les étagères comportant les vis sans fin conditionnées en maintien statique sur les montants,
  • libérer les vis sans fin de leur conditionnement et les visser à fixation verrouillée sur les axes des paliers prémontés, en actionnant ces paliers par l'entraînement du motoréducteur,
  • relier les étagères en liaison rigide par une barre médiane verticale, formant en outre par application au sol support médian des étagères, et
  • fixer à l'extrémité supérieure des montants un bandeau support d'informations relatives à la machine.
The mounting method is characterized by the following successive steps:
  • arranging the amount comprising the set of sheaves and drive belts of the shelves on the geared motor so as to couple the drive belt of the pulley and belt assembly of the amount to the drive pulley of the geared motor,
  • perform the final assembly of the gearmotor on the amount,
  • connecting the two uprights of shelves vertical station by means of two rear bars articulated cross and fixed by their end to each of the uprights,
  • implant the shelves with the worm conditioned in static maintenance on the uprights,
  • release the worm screws of their packaging and screw them with locked fixation on the axes of the pre-assembled bearings, by actuating these bearings by the geared motor drive,
  • connect the shelves in rigid connection by a vertical center bar, further forming by application to the floor median support of the shelves, and
  • attach to the upper end of the uprights a machine information support strip.

On utilise en outre avantageusement une pièce dite peigne à prise sur les filets de la vis sans fin par sa partie dentée active et pincée en encliquetage de fixation sur le profil porteur ou corps d'étagère pour assurer le maintien immobile conditionné des vis sans fin, cette pièce peigne permettant en outre au montage de la vis sur son palier de la translater horizontalement vers son palier de manière à assurer la prise de vissage de sa tige filetée d'axe dans le taraudage correspondant d'axe de palier.Advantageously, a so-called comb piece is used which is gripped on the threads of the worm by its active toothed part and pinched in snap-fastening on the carrier profile or shelf body in order to maintain the worm gear immobile. this piece comb further allowing the mounting of the screw on its bearing to translate it horizontally towards its bearing so as to ensure the tightening of its threaded shaft pin in the corresponding thread of the bearing axis.

Il résulte de cette disposition que relativement aux machines traditionnelles précitées on n'a plus à réaliser l'accouplement fastidieux et délicat d'entraînement de chacune des vis d'étagères sur le montant d'entraînement correspondant, en accouplant de façon ajustée sa poulie et courroie d'entraînement, après montage du palier d'axe, cet accouplement et montage des paliers étant prévu selon l'invention, ajusté en usine, dans le montant correspondant. Ceci épargne un temps de main d'oeuvre spécialisé important.It follows from this provision that relative to the above-mentioned traditional machines it is no longer necessary to perform the tedious and delicate coupling of each of the shelf screws to the corresponding drive post, by fittingly coupling its pulley and drive belt, after mounting of the axis bearing, this coupling and mounting of the bearings being provided according to the invention, adjusted at the factory, in the corresponding amount. This saves a significant amount of specialized labor time.

Comme représenté sur les figures 1 et 2, la machine d'agitation de peinture selon l'invention comporte essentiellement deux montants verticaux 1, sur lesquels sont implantées des étagères 3 d'entraînement de couvercles agitateurs (non représentés), un motoréducteur inférieur 5, une barre médiane verticale 7 reliée aux étagères 3, et un bandeau supérieur vertical 9 assemblé sur les deux montants verticaux 1 de machine.As shown in FIGS. 1 and 2, the agitation machine of paint according to the invention essentially comprises two vertical uprights 1, on which are placed shelves 3 driving agitator lids (not shown), a lower gear motor 5, a vertical center bar 7 connected to the shelves 3, and a vertical upper band 9 assembled on the two vertical uprights 1 machine.

La machine d'agitation est de type à vis sans fin 11 d'entraînement des couvercles agitateurs, lesquels sont engagés à coulissement sur des supports glissières 13 de l'étagère et en prise d'entraînement sur la vis sans fin 11 par un pignon avant en contact avec le filet de la vis.The stirring machine is of worm type 11 driving agitator lids, which are slidably engaged on slide supports 13 of the shelf and in drive engagement on the worm 11 by a front pinion in contact with the thread of the screw.

Les montants 1 supportent les étagères 3 selon une disposition sensiblement horizontale, et selon une hauteur variable de l'une à l'autre selon la dimension des pots de peintures suspendus, les étagères inférieures portant en général les pots les plus gros.The uprights 1 support the shelves 3 in a substantially horizontal arrangement, and according to a height variable from one to the other depending on the size of the hanging paint pots, the lower shelves generally carrying the largest pots.

Le montant gauche 1 sur le dessin enferme l'ensemble 15 des poulies et courroies d'entraînement de chacune des vis sans fin d'étagère, cet ensemble étant accouplé par courroie 17 à la poulie de sortie du motoréducteur, lui-même fixé à la base du montant.The left amount 1 in the drawing encloses the assembly 15 of the pulleys and drive belts of each of the endless rack screws, this assembly being coupled by belt 17 to the output pulley of the gearmotor, itself attached to the basis of the amount.

L'ensemble 15 des poulies et courroies dans le montant et les paliers 19 d'accouplement aux étagères à l'opposé sont fixés ajustés en usine sur le côté interne du montant. Le montant est livré équipé. L'autre montant droit assure à l'aide d'un pied inférieur 21 la seule fonction de support des étagères, opposée à celle du montant gauche.The set of pulleys and belts in the upright and the mating bearings 19 to the opposite shelves are set in the factory on the inner side of the upright. The amount is delivered equipped. The other right upright ensures with the help of a lower foot 21 the only support function of the shelves, opposite that of the left amount.

La barre médiane 7 est reliée rigidement aux étagères 3 et, étant posée au sol, elle assure en outre une fonction de support de la partie médiane des étagères face au poids des pots suspendus.The center bar 7 is rigidly connected to the shelves 3 and, being placed on the ground, it also provides a support function of the middle part of the shelves against the weight of the hanging pots.

Le bandeau supérieur 9 relie les montants à leur partie supérieure et de même, deux barres articulées en croisillon 23 à leur partie inférieure.The upper band 9 connects the uprights to their upper part and likewise, two bars articulated cross 23 at their lower part.

Le montage de la machine est à présent décrit. Celui-ci est effectué rapidement, en un temps inférieur à 15 minutes par machine et ceci sans outils et à donc à la main, par une seule personne.The assembly of the machine is now described. This is done quickly, in less than 15 minutes per machine and this without tools and therefore by hand, by one person.

On commence par disposer le montant d'entraînement 1, tout équipé de son ensemble interne 15 de poulies et courroies d'entraînement et paliers 19 d'entraînement des étagères, sur le support motoréducteur 5. Celui-ci se positionne dans l'évidement intérieur inférieur 25 du montant. Cet évidement 25, sensiblement rectangulaire, comporte deux lumières supérieures verticales distantes 27 permettant la fixation en serrage, chacune, d'une vis à molette de manoeuvre correspondante 29 vissée solidaire du support motoréducteur. Sur le bord avant interne du montant est également formée une lumière verticale 31 dont la partie d'extrémité intérieure 33 est inclinée vers l'avant. Le talon arrière du montant comporte une autre lumière verticale pour l'engagement d'une vis à molette de serrage correspondante 29 solidaire du motoréducteur. Le montant se positionne par introduction de sa lumière inférieure avant 31 sur la vis à molette correspondante 29 du support motoréducteur, en position inclinée naturelle vers l'avant. Cette position (fig. 3) facilite le montage de la courroie 17 d'accouplement de la poulie de sortie de motoréducteur à la poulie en regard de l'ensemble d'entraînement 15 du montant. Lorsque la courroie est montée, le montant est redressé sensiblement en position verticale (fig. 3a), position que l'on peut fixer par serrage de la molette de talon arrière. Le serrage de la courroie est ajusté puis verrouillé en position par la molette supérieure arrière. Les molettes supérieures et inférieures avant sont alors serrées pour verrouiller l'assemblage du montant et du motoréducteur. L'ensemble repose au sol verticalement en position stable étant maintenu par des pieds inférieurs 37 avant et transversal solidaires du support motoréducteur.We begin by arranging the amount of drive 1, fully equipped with its internal assembly 15 pulleys and drive belts and bearings 19 drive shelves on the gearmotor support 5. It is positioned in the inner recess less than 25 of the amount. This recess 25, substantially rectangular, comprises two upper vertical lights remote 27 for fastening in clamping, each of a corresponding screw actuating wheel 29 screwed to the gearmotor support. On the inner front edge of the upright is also formed a vertical light 31 whose inner end portion 33 is inclined forwardly. The rear heel of the upright comprises another vertical light for the engagement of a corresponding clamping screw 29 secured to the geared motor. The amount is positioned by introduction of its lower front light 31 on the corresponding thumbscrew 29 of the gearmotor holder, in natural inclined position forward. This position (FIG 3) facilitates the assembly of the belt 17 for coupling the gearmotor output pulley to the pulley facing the driving assembly 15 of the upright. When the belt is mounted, the upright is substantially upright (Fig. 3a), a position that can be fixed by tightening the rear heel knob. The tightening of the belt is adjusted and then locked in position by the upper rear wheel. The upper and lower front knobs are then tightened to lock the upright and gearmotor assembly. The assembly rests on the ground vertically in a stable position being maintained by lower feet 37 front and transverse integral with the geared motor holder.

Il s'agit ensuite de fermer le carter externe de ce montant bien que cette fermeture puisse être réalisée ultérieurement. Pour des raisons de sécurité et d'isolation des poulies et courroies de l'ensemble d'entraînement, cette fermeture peut être réalisée à ce moment. Elle est illustrée aux figures 10 et 11.It is then necessary to close the outer casing of this amount although this closure can be performed later. For reasons of safety and isolation of the pulleys and belts of the drive assembly, this closure can be achieved at this time. It is illustrated in Figures 10 and 11.

La tôle de carter externe 29 du montant, complémentaire de la tôle interne 41, formant toutes deux en assemblage un boîtier parallélépipédique rectangle, comporte quatre pattes latérales 43, une en bas et une en haut et de chaque côté avant et arrière, à prise en coulissement vertical vers le bas selon flèche dans des lumières complémentaires 45 de la tôle de carter intérieur. La tôle de carter extérieur 39 comporte en outre une languette supérieure 47, sur chacun de ses côtés opposés avant et arrière, découpée dans la partie supérieure de côté de la tôle. Cette languette 47 peut être tournée vers l'intérieur avec rappel ferme, en sorte que lorsque la tôle de carter externe 39 est engagée vers le bas sur la tôle de carter interne 41 avec ajustement de la hauteur des bords au niveau supérieur, cette languette en dépassant du bord supérieur du carter interne, revient vers l'intérieur et sous celui-ci, empêchant alors toute remontée du carter interne relativement au carter externe, sauf à tirer cette languette vers l'extérieur au risque de la déformer par exemple, avec un outil à lame.The outer casing plate 29 of the upright, complementary to the internal plate 41, both forming a rectangular parallelepipedal casing assembly, comprises four lateral tabs 43, one at the bottom and one at the top and at each front and rear side, to be gripped. vertical sliding down arrow according to complementary lights 45 of the inner housing plate. The outer casing plate 39 further includes an upper tab 47, on each of its opposite front and rear sides, cut in the upper side of the sheet. This tongue 47 can be turned inwards with firm return, so that when the casing plate 39 is engaged down on the inner housing plate 41 with adjustment of the height of the edges to the upper level, this tab protruding from the upper edge of the inner casing, back inwards and below it, thereby preventing any raising the inner casing relative to the outer casing, except pulling the tongue outward at the risk of deforming for example, with a blade tool.

Il s'agit maintenant de relier les deux montants 1 supports d'étagère. Cette opération est réalisée au moyen de deux barres en croisillon 23 articulées en leur milieu pour inscrire par leurs extrémités un rectangle; les extrémités comportent des encoches inférieures 49, disposées en symétrie par rapport à l'articulation, et qui viennent en engagement dans des pièces crochets arrière (non représenté) en saillie de chacun des montants support d'étagère par deux sur chacun des montants au niveau inférieur.It is now a matter of connecting the two uprights 1 shelf supports. This operation is performed by means of two cross bars 23 articulated in their middle to inscribe at their ends a rectangle; the ends comprise lower notches 49, arranged symmetrically with respect to the hinge, and which engage in rear hook pieces (not shown) projecting from each of the shelf support uprights by two on each of the uprights at the inferior.

Ces barres en croisillon, dès qu'elles sont montées sur les montants, les relient en position verticale, formant alors gabarit de montage des étagères support des couvercles agitateurs, lequel est décrit ci-après.These cross bars, as soon as they are mounted on the uprights, connect them in a vertical position, then forming the mounting template of the support shelves of the agitator lids, which is described below.

Les étagères 3 sont livrées avec leur vis sans fin 11 (fig. 6), maintenue conditionnée immobile au moyen d'une pièce dite peigne 51 engagée par sa partie active de peigne sur les filets de la vis, dans leur fente avant 53, et fixée encliquetée sur le corps de l'étagère.The shelves 3 are delivered with their worm 11 (FIG 6), kept stationary motionless by means of a so-called comb piece 51 engaged by its active comb part on the threads of the screw, in their front slot 53, and fixed snapped onto the body of the shelf.

Chaque étagère, successivement, est enfilée par son extrémité libre 55 (figure 4) dans un évidement complémentaire 57 du montant droit, convenablement formé à hauteur sur le montant pour chaque étagère à supporter.Each shelf, successively, is threaded by its free end 55 (Figure 4) in a complementary recess 57 of the right upright, suitably formed height on the amount for each shelf to support.

L'extrémité de l'étagère comporte deux encoches verticales latérales inférieures 59, par lesquelles elle peut être descendue engagée en verrouillage transversal dans ledit évidement 57, puis translatée vers l'arrière (figure 5) dans un décrochement étroit inférieur 61, empêchant toute remontée de l'extrémité d'étagère et sa translation vers l'avant.The end of the shelf comprises two lower lateral vertical notches 59, by which it can be lowered engaged in transverse locking in said recess 57, and then translated backwards (FIG. 5) into a lower narrow recess 61, preventing any ascent. the shelf end and its forward translation.

L'étagère en position de coulissement libre dans l'évidement 57 de montant est amenée vers le palier correspondant 19 de vis sans fin, lequel est préfixé à hauteur adéquate sur le montant d'entraînement ainsi que précité. L'étagère est alors encliquetée par son ouverture d'extrémité 63 (fig. 7a) sur le corps complémentaire du palier 19. En fin d'engagement (fig. 7b), l'étagère est verrouillée automatiquement en position par encliquetage de crochetage des parties.The shelf in free sliding position in the recess 57 of the upright is brought to the corresponding bearing 19 worm, which is prefixed to adequate height on the amount of training as aforesaid. The shelf is then snapped by its end opening 63 (FIG 7a) on the complementary body of the bearing 19. In the end 7b), the shelf is automatically locked in position by snap hooking parts.

L'accouplement de la vis sans fin 11 sur son palier 19 est obtenu de façon simple et rapide ainsi que décrit ci-après en référence à la fig. 7.The coupling of the worm 11 on its bearing 19 is obtained simply and quickly as described below with reference to FIG. 7.

Chaque vis 11 comporte à son extrémité, côté palier, un joint d'accouplement 65 de type à tampon ou tête en caoutchouc 67, à deux embouts filetés opposés, dont l'un est vissé dans l'extrémité de vis par un taraudage complémentaire et l'autre 69 est destiné à être vissé au palier. Ce joint d'accouplement, permettant une liaison axiale souple entre la vis et son palier (fonctions cardan, amortisseur et sécurité d'entraînement) est destiné à être vissé par son embout d'extrémité 69 dans un taraudage axial complémentaire 71 de l'arbre intérieur du palier.Each screw 11 has at its end, on the bearing side, a coupling coupling 65 of the buffer type or rubber head 67, with two opposite threaded ends, one of which is screwed into the end of the screw by a complementary tapping and the other 69 is intended to be screwed to the bearing. This coupling joint, allowing a flexible axial connection between the screw and its bearing (cardan functions, damper and drive safety) is intended to be screwed by its end cap 69 in a complementary axial tapping 71 of the shaft inside the landing.

Pour ce faire, on dégage la pièce peigne 51 de son encliquetage de conditionnement, on conserve la prise de peigne sur le filet de vis et on amène la vis 11 en translation vers le palier 19, de façon à assurer le contact entre l'embout fileté de joint 69 et le taraudage correspondant 71 d'arbre de palier. L'arbre de palier est entraîné au moteur en rotation assurant ledit vissage de l'arbre de palier sur l'embout correspondant de joint d'accouplement de la vis en rotation. A la fin de l'opération de vissage, la liaison vient en butée et entraîne la vis. L'accouplement de la vis sans fin au palier de montant étant réalisé, l'entraînement de l'arbre du palier concourt à parfaire, par l'entraînement toujours dans le même sens, la liaison de vissage entre la vis et son palier.To do this, the comb piece 51 is disengaged from its packaging snap, the comb hold is retained on the screw thread and the screw 11 is brought into translation towards the bearing 19, so as to ensure contact between the endpiece. threaded joint 69 and the corresponding thread 71 of the bearing shaft. The bearing shaft is rotatably driven to the motor providing said screwing of the bearing shaft to the corresponding coupling end of the rotating screw. At the end of the screwing operation, the connection comes into abutment and drives the screw. Since the coupling of the worm to the upright bearing is carried out, the drive of the bearing shaft contributes to perfecting, by the drive always in the same direction, the screw connection between the screw and its bearing.

Le montage des autres étagères est réalisé de la même façon que précité.The assembly of the other shelves is made in the same way as mentioned above.

Lorsque les étagères sont toutes montées, la barre médiane 7 de liaison des étagères peut être montée (figures 8 et 9) ; cette barre comporte des pièces d'accrochage 73 encliquetées aux étagères, à prise sur des lumières adéquates supérieures 75 des étagères et convenablement fixées chacune à hauteur sur la barre pour correspondre au positionnement de hauteur des étagères. Ces pièces comportent une lumière verticale supérieure 77 recevant, avec possibilité d'ajustement de hauteur sur leur longueur, la tête moletée d'une vis 79 à serrage manuel rapide vissée dans le corps de la barre. La barre 7 est donc enfoncée vers le bas selon flèche pour permettre l'engagement encliqueté des pièces d'accrochage 73 sur les étagères puis le serrage des vis à molette de manoeuvre 79 est réalisé, ajusté à chaque étagère, l'extrémité de la barre reposant au sol.When the shelves are all mounted, the middle bar 7 connecting shelves can be mounted (Figures 8 and 9); this bar has attachment parts 73 snapped to the shelves, to take on adequate lights above 75 shelves and suitably each fixed at height on the bar to match the height positioning of the shelves. These parts comprise an upper vertical light 77 receiving, with the possibility of height adjustment along their length, the knurled head of a screw 79 fast manual tightening screwed into the body of the bar. The bar 7 is thus depressed downwards according to arrow to allow the latched engagement of the attachment parts 73 on the shelves and the tightening of the adjusting thumbscrew 79 is made, adjusted to each shelf, the end of the bar resting on the ground.

Il ne reste plus qu'à monter le bandeau supérieur 9 sur l'extrémité des montants (figures 12, 13).It remains only to mount the upper band 9 on the ends of the uprights (Figures 12, 13).

Le bandeau 9 comporte deux pattes d'accrochage latéral opposées 81 s'engageant en encliquetage dans des encoches complémentaires 83 prévues à l'extrémité supérieure avant des montants. Le bandeau 9 étant déposé verticalement selon flèche sur la partie avant supérieure des montants, les pattes du bandeau viennent dans les encoches respectives du montant et s'y accrochent en verrouillage par engagement des crochets vers l'avant tandis que le bandeau est plaqué sur les montants.The strip 9 comprises two opposite lateral latching lugs 81 engaging in snap-fit in complementary notches 83 provided at the upper end of the uprights. The headband 9 being vertically deposited according to arrow on the upper front portion of the uprights, the tabs of the headband come into the respective notches of the upright and hang in lock by engaging the hooks forward while the headband is pressed on the amounts.

D'autres accessoires peuvent encore être montés, tel que le commutateur 85 de commande de fonctionnement de la machine, également encliqueté sur le montant d'entraînement 1, avec prise de contact automatique sur le circuit d'alimentation électrique de la machine.Other accessories can still be mounted, such as the machine operation control switch 85, also snapped onto the drive post 1, with automatic contact on the power supply circuit of the machine.

Ce qui précède montre l'extrême facilité du montage de la machine d'agitation de peinture selon l'invention, réalisé, sans outils particuliers, et avec accrochage automatique des composants, dans l'ordre décrit précité, par une personne en un temps inférieur à 15 minutes, sans nécessité d'ajustement des accouplements d'entraînements.The above shows the extreme ease of assembly of the paint stirring machine according to the invention, carried out without special tools, and with automatic fastening of the components, in the order described above, by a person in a shorter time. at 15 minutes, without the need for adjustment of the drive couplings.

On notera à titre de variante de réalisation de la machine (fig. 14) que le groupe motoréducteur 5 peut être été remplacé par un ensemble de petits moteurs électriques 87, disposés dans le montant à la place des poulies de palier d'étagères et entraînant directement les vis sans fin d'étagère, par l'intermédiaire des paliers externes 19 inchangés tel que décrits ci-dessus, les moteurs pouvant en outre tourner à des vitesses variables distinctes l'une de l'autre. Cette disposition autorise en outre une plus grande liberté de positionnement des étagères sans être liée à l'ensemble des poulies et courroies du montant.It will be noted as an alternative embodiment of the machine (FIG 14) that the geared motor unit 5 can be replaced by a set of small electric motors 87, arranged in the upright in place of the shelf bearing pulleys and causing directly the shelf worm, through the unchanged external bearings 19 as described above, the motors can also rotate at variable speeds distinct from each other. This arrangement also allows greater freedom of positioning shelves without being linked to all the pulleys and straps of the amount.
