The agitator lid, especially for tins of paint supported beneath racks (3), has a first helical gear (9) for engaging with an endless drive screw and fixed to the top end of an agitator spindle (9), and a detachable sprocket (19) to engage with a chain (17). The sprocket is of greater diameter than the helical gear and has hooks on its under surface to engage with the gear for a coaxial mounting. The hooks on the sprocket are spaced at regular intervals round its under surface, and can be in different shapes, e.g. shaped to engage with the helical gear's teeth for easy fitting and removal.

Description

L'invention concerne un couvercle agitateur à transmission de mouvement double pour les machines d'agitation de peinture et en particulier un couvercle agitateur à transmission de mouvement double s'adaptant sur les machines d'agitation de peinture à chaînes d'entraînement d'étagère et sur les machines à vis sans fin d'entraînement d'étagère.The invention relates to a stirrer cover with double movement transmission for paint stirring machines and in particular to a stirrer cover with double movement transmission suitable for paint stirring machines with shelf drive chains. and on the shelf drive worm machines.

On sait que les machines d'agitation de peinture, de type recevant des couvercles agitateurs avec leurs pots de peinture, montés en suspension sur des étagères, par des glissières transversales, comportent un dispositif d'entraînement des couvercles agitateurs sur chaque étagère. Ce dispositif d'entraînement est soit à chaîne disposée en boucle sur chacune des étagères, soit à vis sans fin s'étendant sur la longueur de chacune des étagères. Les couvercles agitateurs comportent un pignon supérieur d'entraînement de l'axe agitateur spécifique du dispositif d'entraînement, à denture d'engrenage hélicoïdale pour l'entraînement par la vis sans fin et à denture d'engrenage droite pour l'entraînement par chaîne, ce pignon venant en prise avec la chaîne ou la vis sans fin par translation adéquate du couvercle agitateur sur ses glissières. Ces pignons sont donc différents selon que le dispositif d'entraînement est à chaîne ou vis sans fin et ne permettent pas la compatibilité d'entraînement sur un même couvercle agitateur.It is known that paint stirring machines, of the type receiving agitator covers with their paint cans, mounted in suspension on shelves, by transverse slides, include a device for driving the agitator covers on each shelf. This drive device is either a chain arranged in a loop on each of the shelves, or a worm screw extending over the length of each of the shelves. The agitator covers have an upper drive pinion for the specific agitator axis of the drive device, with helical gear teeth for the worm gear drive and straight gear teeth for the chain drive , this pinion coming into engagement with the chain or the worm by adequate translation of the agitator cover on its slides. These sprockets are therefore different depending on whether the drive device is chain or worm and do not allow drive compatibility on the same agitator cover.

Cette disposition impose de détenir des jeux de couvercles agitateurs spécifiques des machines d'agitation selon qu'elles sont de type à entraînement par chaînes ou à entraînement par vis sans fin.This provision requires having sets of agitator covers specific to the stirring machines depending on whether they are of the chain drive or worm drive type.

L'invention vise à remédier à cet inconvénient et propose un couvercle agitateur pour les machines d'agitation de peinture à chaînes d'entraînement et pour les machines d'agitation de peinture à vis sans fin d'entraînement, du type supporté en suspension sur les étagères des machines d'agitation au moyen de glissières transversales et comportant un pignon supérieur d'entraînement de l'axe agitateur venant en prise en service sur l'élément d'entraînement de machine, chaîne ou vis sans fin d'étagère, lorsqu'il est convenablement positionné relativement audit élément d'entraînement d'étagère, couvercle caractérisé en ce qu'il comporte un premier pignon d'engrenage hélicoïdal pour la prise de mouvement sur un élément à vis sans fin d'une machine d'agitation à entraînement par vis sans fin, monté fixe à l'extrémité supérieure de l'axe agitateur du couvercle, et un second pignon amovible d'engrenage droit et de diamètre plus grand que ledit premier pignon, destiné à venir en prise en service sur un élément à chaîne d'entraînement de machine d'agitation, ce second pignon comportant des crochets sur sa face inférieure, destinés à s'engager en prise sur le premier pignon par des éléments récepteurs adéquats pour permettre son montage coaxial sur ce dernier. Le second pignon est avantageusement conformé pour que ses éléments de denture d'engrenage , lorsqu'il est monté crocheté sur le premier pignon, soient sensiblement dans le même plan que ceux du premier pignon. Cette particularité répond aux caractéristiques constitutives et de sécurité des machines d'agitation.The invention aims to remedy this drawback and proposes an agitator cover for paint stirring machines with drive chains and for worm gear paint stirring machines, of the type supported in suspension on machine shelves stirring by means of transverse slides and comprising an upper pinion drive pinion coming into service on the machine drive element, chain or endless shelf screw, when it is suitably positioned relative to said shelf drive element, cover characterized in that it comprises a first helical gear pinion for the power take-off on a worm element of a stirring machine with screwless drive end, fixedly mounted at the upper end of the agitator axis of the cover, and a second removable pinion of spur gear and of diameter larger than said first pinion, intended to come into service on a chain element of stirring machine drive, this second pinion having hooks on its underside, intended to engage in engagement on the first pinion by suitable receiving elements to allow its mounting coaxial age on the latter. The second pinion is advantageously shaped so that its gear teeth, when it is hooked on the first pinion, are substantially in the same plane as those of the first pinion. This particularity meets the constitutive and safety characteristics of stirring machines.

Naturellement, les crochets du second pignon peuvent avoir une forme variable de même que les éléments récepteurs complémentaires du premier pignon (par exemple, de simples trous de prise complémentaires des crochets dans le corps du pignon).Naturally, the hooks of the second pinion can have a variable shape as can the complementary receiving elements of the first pinion (for example, simple holes for taking complementary hooks in the body of the pinion).

Selon des caractéristiques avantageuses de l'invention, les crochets du second pignon sont disposés sur un cercle coaxial au pignon et de diamètre celui du premier pignon. Ils sont positionnés régulièrement sur ce cercle, selon un angle égal de l'un à l'autre, et sont conformés pour venir en prise sur les dents de périphérie du premier pignon. Ces crochets peuvent être au nombre de trois, positionnés à 120° l'un de l'autre.According to advantageous features of the invention, the hooks of the second pinion are arranged on a circle coaxial with the pinion and of diameter that of the first pinion. They are positioned regularly on this circle, at an angle equal to one another, and are shaped to engage on the periphery teeth of the first pinion. These hooks can be three in number, positioned at 120 ° from one another.

Les crochets peuvent être de type à rappel de crochetage élastique permettant le montage rapide en encliquetage du second pignon sur le premier par simple poussée et, inversement, son démontage facile par écartement des crochets pour autoriser la mise en service du premier pignon seul sur une machine à vis sans fin d'entraînement.The hooks can be of the hook picking type elastic allowing quick mounting by snap-fastening of the second pinion on the first by a simple push and, conversely, its easy disassembly by spacing the hooks to authorize the putting into service of the first pinion alone on a worm machine.

Les crochets sont identiques, ils peuvent avoir une largeur équivalente à deux dents d'engrenage du premier pignon pour venir en prise chacun sur deux dents de ce pignon. Ils peuvent comporter en outre un pion médian en saillie correspondant au creux entre deux dents d'engrenage du premier pignon, interdisant le glissement en rotation du second pignon sur le premier.The hooks are identical, they can have a width equivalent to two gear teeth of the first pinion to engage each on two teeth of this pinion. They may further comprise a projecting median pin corresponding to the hollow between two gear teeth of the first pinion, preventing the sliding of the second pinion in rotation on the first.

Le deuxième pignon est de préférence à forme de disque ouvert sur sa face inférieure et pourvu de dents d'engrenage droit sur sa périphérie, et comporte des crochets à forme de J destinés à venir en prise sur les éléments de denture d'engrenage du premier pignon avec le nez de crochetage (jambe transversale inférieure du J) pincé à leur partie inférieure. Il reçoit le premier pignon par son ouverture, monté maintenu coaxialement et sans jeu par lesdits crochets à forme de J.The second pinion is preferably in the form of a disc open on its underside and provided with straight gear teeth on its periphery, and comprises J-shaped hooks intended to engage the gear teeth of the first. pinion with hooking nose (lower transverse leg of J) pinched at their lower part. It receives the first pinion by its opening, mounted maintained coaxially and without play by said hooks in the form of J.

Il résulte de cette disposition que le premier pignon du couvercle agitateur, fixé à demeure sur l'axe agitateur, permet la prise d'entraînement rotative de l'axe agitateur avec la vis sans fin d'entraînement correspondante d'une machine d'agitation à vis sans fin et que le second pignon, monté de façon rapide par encliquetage sur le premier pignon, permet la prise d'entraînement avec la chaîne d'entraînement d'une machine d'agitation à chaîne d'entraînement. Le démontage de ce second pignon s'obtient par une manoeuvre inverse et permet le retour à l'entraînement du couvercle agitateur sur une machine à vis sans fin d'entraînement. Un couvercle agitateur selon l'invention peut donc être entraîné indifféremment sur une machine d'agitation à chaîne ou vis sans fin d'entraînement.It follows from this arrangement that the first pinion of the agitator cover, fixed permanently to the agitator axis, allows the rotary drive take-up of the agitator axis with the corresponding drive worm of a stirring machine. and that the second pinion, mounted quickly by snap-fastening on the first pinion, allows the drive to be taken with the drive chain of a stirring machine with drive chain. The disassembly of this second pinion is obtained by a reverse operation and allows the return to the drive of the agitator cover on a worm drive machine. An agitator cover according to the invention can therefore be driven either on a chain or worm drive stirring machine.

L'invention est décrite ci-après à l'aide d'un exemple de réalisation et en référence au dessin annexé, sur lequel :

  • La figure 1 est une vue en coupe d'un couvercle agitateur selon l'invention en prise sur un élément à vis sans fin d'entraînement d'étagère d'une machine d'agitation de peinture,
  • La figure 2 est une vue de dessus schématique montrant l'entraînement du premier pignon fixe de couvercle agitateur par la vis sans fin de machine.
  • La figure 3 est une vue en coupe analogue à la figure 1 d'un couvercle agitateur selon l'invention en prise sur une chaîne d'entraînement d'étagère de machine d'agitation à chaîne, et
  • La figure 4 est une vue analogue à la figure 2 montrant la prise du second pignon du couvercle agitateur selon la figure 3 avec la chaîne d'entraînement correspondante d'étagère de machine d'agitation à chaîne.
The invention is described below using an embodiment and with reference to the accompanying drawing, on which :
  • FIG. 1 is a sectional view of an agitator cover according to the invention engaged on a worm drive element of the shelf drive of a paint stirring machine,
  • Figure 2 is a schematic top view showing the drive of the first fixed pinion of agitator cover by the machine worm.
  • FIG. 3 is a sectional view similar to FIG. 1 of an agitator cover according to the invention engaged on a drive chain of a chain agitator machine shelf, and
  • Figure 4 is a view similar to Figure 2 showing the engagement of the second sprocket of the agitator cover according to Figure 3 with the corresponding drive chain of chain agitator machine shelf.

Avec référence au dessin, la figure 1 représente un couvercle agitateur 1 selon l'invention monté sur une étagère 3 de machine d'agitation de peinture à vis sans fin d'entraînement 5. Le couvercle agitateur 1 est suspendu, de même que d'autres couvercles agitateurs identiques avec leurs pots de peinture inférieurs, à des glissières transversales classiques d'étagères (non représentées). Il est positionné sur ces dernières pour venir en prise par son pignon supérieur de prise de mouvement 7 sur la vis sans fin d'entraînement 5, comme représenté encore sur la figure 2. Le pignon 7, fixé à demeure à l'extrémité supérieure de l'axe agitateur 9 et entraînant ce dernier en rotation, est à denture d'engrenage hélicoïdale 11 complémentaire de celle de la vis sans fin 5. Ce pignon est en matière plastique dure, étant goupillé sur l'axe agitateur du couvercle. Il est protégé par un carter 13, lequel est ouvert sur sa face avant 15 pour permettre la prise de mouvement avec la vis sans fin 5.With reference to the drawing, FIG. 1 represents an agitator cover 1 according to the invention mounted on a shelf 3 of a worm-paint paint stirring machine 5. The agitator cover 1 is suspended, as is other identical agitator covers with their lower paint cans, to conventional transverse shelf slides (not shown). It is positioned on the latter to engage by its upper power take-off pinion 7 on the drive worm 5, as also shown in FIG. 2. The pinion 7, fixed permanently to the upper end of the agitator axis 9 and driving the latter in rotation, has helical gear teeth 11 complementary to that of the worm screw 5. This pinion is made of hard plastic, being pinned on the agitator axis of the cover. It is protected by a casing 13, which is open on its front face 15 to allow movement to be taken with the worm 5.

La figure 3 montre l'entraînement du couvercle agitateur 1 sur une machine d'agitation à chaînes d'entraînement 17 des étagères. Un second pignon en métal 19, engrenant avec la chaîne d'entraînement d'étagère 17, est monté sur le pignon à denture hélicoïdale 7 fixé sur l'axe agitateur 9. Ce pignon est amovible. Il est à denture d'engrenage droit 21 venant en service dans le même plan que celle 11 du pignon à denture hélicoïdale 7. Il a la forme d'un disque 23 ouvert à sa partie inférieure, en 25, et pourvu de dents d'engrenage 21 à sa périphérie. Il comporte des crochets 27 dans son ouverture inférieure 25 à forme d'arc en plan, disposés coaxialement au pignon et sur un cercle de diamètre égal à celui du pignon à denture hélicoïdale 7. Les crochets 27, au nombre de trois et à 120° l'un de l'autre, sont à forme de J en section. Leur largeur est égale à deux dents 11 du pignon à denture hécoïdale. Le nez 29 de crochet est tourné vers l'intérieur à une distance de la paroi intérieure 31 du disque égale à la hauteur des dents d'engrenage hélicoïdale 11 du premier pignon. Ces crochets sont à rappel de crochetage élastique.Figure 3 shows the drive of the agitator cover 1 on a stirring machine with drive chains 17 of the shelves. A second metal gable 19, meshing with the shelf drive chain 17, is mounted on the helical toothed pinion 7 fixed on the agitator axis 9. This pinion is removable. It has a spur gear 21 coming into service in the same plane as that 11 of the pinion with helical teeth 7. It has the shape of a disc 23 open at its lower part, at 25, and provided with teeth gear 21 at its periphery. It has hooks 27 in its lower opening 25 in the form of a planar arc, arranged coaxially with the pinion and on a circle of diameter equal to that of the pinion with helical teeth 7. The hooks 27, three in number and at 120 ° from each other, are in the form of J in section. Their width is equal to two teeth 11 of the pinion with hecoidal toothing. The hook nose 29 is turned inward at a distance from the inner wall 31 of the disc equal to the height of the helical gear teeth 11 of the first pinion. These hooks are reminiscent of elastic hooking.

Le montage de ce second pignon d'engrenage droit 19 s'obtient aisément en l'introduisant dans l'ouverture 25 de carter, en l'appliquant sur le pignon fixe de denture hélicoïdale 7, coaxialement à celui-ci, et en engageant en encliquetage chacun de ses crochets 27 sur le premier pignon 7, par pression sur chacun d'eux à l'ouverture avant 25 de carter et en tournant convenablement le pignon à cet effet. Lorsque les trois crochets 27 sont engagés en prise sur les dents du premier pignon 7, le pignon d'engrenage droit 19 est alors monté. Il est crocheté sans jeu sur le pignon 7, coaxialement à celui-ci, en y étant parfaitement solidaire. Le couvercle agitateur ainsi équipé du pignon amovible d'engrenage droit à prise sur la chaîne d'entraînement d'étagère peut alors être mis en service comme un couvercle agitateur classique à pignon d'engrenage droit classique fixé à demeure sur l'axe agitateur, de même diamètre et à un positionnement équivalent de translation sur les glissières de suspension d'étagère.The mounting of this second spur gear pinion 19 is easily obtained by introducing it into the housing opening 25, by applying it to the fixed pinion with helical teeth 7, coaxially therewith, and by engaging in snap-fastening each of its hooks 27 on the first pinion 7, by pressing on each of them at the front opening 25 of the casing and turning the pinion appropriately for this purpose. When the three hooks 27 are engaged in engagement with the teeth of the first pinion 7, the spur gear 19 is then mounted. It is hooked without play on the pinion 7, coaxially with the latter, while being perfectly integral therewith. The agitator cover thus equipped with the removable straight gear pinion engaged on the shelf drive chain can then be put into service like a conventional agitator cover with conventional right gear pinion permanently fixed to the agitator axis, of the same diameter and at an equivalent translation position on the shelf suspension rails.

Le démontage de ce pignon s'obtient de façon toute aussi aisée en écartant chacun des crochets 27 et en les dégageant des dents du premier pignon 7, ceci sur la face avant 25 de carter 13 au moyen d'une lame de tourne-vis introduite par une fente adéquate 33 formée sur la surface du disque 23, sensiblement au droit de chacun des crochets 27. Lorsque le pignon est enlevé, le couvercle peut à nouveau être mis en service sur une machine d'agitation à vis sans fin d'entraînement comme un couvercle agitateur à entraînement par vis sans fin classique.The disassembly of this pinion is obtained just as easily by removing each of the hooks 27 and releasing them teeth of the first pinion 7, this on the front face 25 of casing 13 by means of a screwdriver blade introduced by a suitable slot 33 formed on the surface of the disc 23, substantially in line with each of the hooks 27.
