Abstract
Description
La présente invention a pour objet un dispositif d'application de mélangesThe subject of the present invention is a device for applying mixtures
de produits ayant une viscosité très importante ou encore de liquides relativement épais tels que des peintures et qui doivent être mélangés à des dosages très précis, ces dosages devant être adaptés à chaque cas d'utilisation. products with a very high viscosity or relatively thick liquids such as paints and which must be mixed at very precise dosages, these dosages must be adapted to each use case.
Ces produits peuvent, par exemple, être des colles constituées d'un produit dit produit de base, qui est la colle proprement dite, à laquelle doit être associé, à l'instant de l'application, un deuxième produit, appelé selon les cas durcisseur ou accélérateur . These products may, for example, be glues consisting of a product called base product, which is the glue itself, to which must be associated, at the time of application, a second product, called depending on the case hardener or accelerator.
La proportion du deuxième produit par rapport au premier, peut varier de 1 % 10 à 25 % ou même plus. The proportion of the second product relative to the first may vary from 1% to 25% or even more.
Dans la pratique, l'application de ce genre de produits se heurte à de grosses difficultés, du fait du fort écart de dosage entre deux produits épais avec un débit d'application variable, le tout associé à des pertes de charges importantes; de sorte que les installations existantes sont coûteuses et peu fiables. In practice, the application of this type of product faces great difficulties, because of the large difference in dosage between two thick products with a variable rate of application, all associated with significant pressure losses; so existing facilities are expensive and unreliable.
Dans ces installations, on utilise soit des pompes à engrenages, soit des pompes à piston. In these installations, either gear pumps or piston pumps are used.
Les pompes à engrenages ainsi que les pompes péristaltiques présentent l'avantage d'être précises, mais présentent l'inconvénient de ne pas permettre des débits importants et de ne pas être utilisables, de façon satisfaisante, pour des pressions élevées. De plus, elles nécessitent des pompes de gavage. Gear pumps as well as peristaltic pumps have the advantage of being precise, but have the disadvantage of not allowing high flow rates and not being usable, satisfactorily, for high pressures. In addition, they require booster pumps.
Les pompes à piston peuvent fournir un débit et une pression importants, mais leur précision n'est pas suffisante pour ces forts écarts de dosage. Piston pumps can provide significant flow and pressure, but their accuracy is not sufficient for these large dosing differences.
La présente invention a pour objet d[e porter remède à ces défauts. The object of the present invention is to remedy these defects.
Selon l'invention, l'installation d'application de mélanges de produits à hautes viscosités à des dosages très précis, mais pouvant être modifiés à volonté, est caractérisée par le fait qu'elle est constituée d'une part d'une pompe à piston à mouvement alternatif et d'au moins une pompe à engrenages ou péristaltique, la liaison entre la pompe à piston et la/ou les pompes à engrenages étant réalisée par l'intermédiaire d'un bloc de commande comportant d'une part un mécanisme transformant le mouvement linéaire alternatif du piston de la pompe à piston en un mouvement rotatif et d'autre part un variateur de vitesse recevant ledit mouvement rotatif et le transmettant à l'axe moteur de la ou des pompes à engrenages avec le rapport souhaité. According to the invention, the apparatus for applying mixtures of products with high viscosities at very precise dosages, but which can be modified at will, is characterized in that it consists on the one hand of a pump with reciprocating piston and at least one gear or peristaltic pump, the connection between the piston pump and the gear pump or pumps being carried out via a control block comprising on the one hand a mechanism transforming the reciprocating linear motion of the piston of the piston pump into a rotary motion and, on the other hand, a speed variator receiving said rotational movement and transmitting it to the motor axis of the gear pump (s) with the desired ratio.
A titre d'exemple et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés: - Figure 1, un exemple de dispositif connu avec pompes à engrenages.

La figure 1 représente un dispositif connu fonctionnant au moyen de deux pompes à engrenages. Figure 1 shows a known device operating by means of two gear pumps.
Les produits A et B sont pompés pair les pompes 1 et 2 respectivement et sont envoyés dans une buse d'application 3 où ils sont mélangés. Les produits A et B sont puisés dans des réservoirs 4 et 5 par des pompes de gavage à pistons 6 et 7, de façon que les pompes à engrenages n'aient pas à aspirer les produits A et B. Les deux pompes à engrenages 1 et 2 sont entraînées par les moteurs 8 et 9, respectivement, le rapport des vitesses des moteurs 8 et 9 étant déterminés par le calculateur 10 de façon à obtenir le dosage désiré des produits A et B. La figure 2 représente un autre dispositif connu fonctionnant au moyen de deux pompes à pistons. Products A and B are pumped by pumps 1 and 2 respectively and are sent to an application nozzle 3 where they are mixed. Products A and B are drawn from tanks 4 and 5 by reciprocating booster pumps 6 and 7, so that the gear pumps do not have to suck up products A and B. Both gear pumps 1 and 5 2 are driven by the motors 8 and 9, respectively, the ratio of the speeds of the motors 8 and 9 being determined by the computer 10 so as to obtain the desired dosage of the products A and B. Figure 2 shows another known device operating at means of two piston pumps.
Le produit A, qui est le produit de base qui est, en général, à haute viscosité et dont le volume utilisé est le plus important, est alimenté par une pompe à piston 13, à double effet, ayant deux chambres de volumes identiques, actionné par un moteur 15 équilibré en pression, de façon que le débit et la pression du liquide pompé soient les mêmes quel que soit le sens de déplacement de l'ensemble. Product A, which is the basic product which is generally of high viscosity and the volume used is the largest, is fed by a piston pump 13, double-acting, having two chambers of identical volumes, actuated by a motor 15 balanced in pressure, so that the flow rate and the pressure of the pumped liquid are the same regardless of the direction of movement of the assembly.
Le produit A est acheminé vers la buse 16 par la canalisation 17. Product A is conveyed to the nozzle 16 via line 17.
Le produit B est contenu dans une cartouche 18 dont le volume est nettement plus petit que celui du fût 14 de produit A. Le doseur est constitué par une petite pompe à piston 19 dont le piston 20 est 5 piloté pneumatiquement par un boîtier de commande qui émet des pulses en fréquence variable, en fonction du dosage à obtenir. The product B is contained in a cartridge 18 whose volume is significantly smaller than that of the drum 14 of product A. The dispenser is constituted by a small piston pump 19 whose piston 20 is pneumatically controlled by a control box which emits pulses in variable frequency, depending on the dosage to be obtained.
Les deux types d'installations ne donnent pas entièrement satisfaction à cause des imperfections, mentionnées plus haut, des pompes à engrenages ou des pompes à pistons. The two types of installations are not entirely satisfactory because of the imperfections, mentioned above, of gear pumps or piston pumps.
Les figures 3, 4, 5 et 6 illustrent l'invention. Figures 3, 4, 5 and 6 illustrate the invention.
Selon l'invention, on va combiner une pompe à piston pour le produit A, de façon à avoir puissance et débit et une pompe à engrenages ou pompe péristaltique pour le produit B, de façon à avoir la précision du dosage. According to the invention, a piston pump will be combined for the product A, so as to have power and flow and a gear pump or peristaltic pump for the product B, so as to have the precision of the dosage.
Pour cela il faut transformer le mouvement de translation de va et vient du 15 piston d'une pompe à piston, en un mouvement rotatif. For this purpose, the reciprocating movement of the piston of a piston pump must be converted into a rotary motion.
Pour cela, le piston de la pompe 13 à produit A est attelé à une crémaillère 20. For this, the piston of the pump 13 to product A is coupled to a rack 20.
Pour simplifier les figures, la pompe 13, n'est pas représentée sur les figure 3, 4 et 5, seule la crémaillère 20 étant représentée. To simplify the figures, the pump 13 is not shown in Figures 3, 4 and 5, only the rack 20 being shown.
Les pignons 21 et 22 identiques, qui engrènent sur la crémaillère 20, sont reliés chacun à un pignon 21a, 22a, par un mécanisme à roue libre de façon que selon le sens de déplacement de la crémaillère 20, seul un des deux pignons 21a soit entraîné en rotation, l'autre 22a étant entraîné lorsque la crémaillère 20 se déplace dans l'autre direction. The identical pinions 21 and 22, which mesh with the rack 20, are each connected to a pinion 21a, 22a by a freewheeling mechanism so that, in the direction of movement of the rack 20, only one of the two pinions 21a is rotated, the other 22a being driven when the rack 20 moves in the other direction.
Lorsque la crémaillère 20 se déplace selon la flèche F, elle entraîne le pignon 21 qui entraîne le pignon 21a lequel tourne dans le sens horaire et entraîne le pignon 24 dans le sens anti-horaire: tandis que le pignon 22 tourne sans entraîner le pignon 22a. Lorsque la crémaillère 20 se déplace dans la direction opposée à la flèche F, le pignon 22 entraîne le pignon 22a qui tourne dans le sens anti-horaire et engrène sur un pignon intermédiaire 23, de sorte que le pignon 24 est entraîné dans le même sens anti-horaire; le pignon 21 tournant sans entraîner le pignon 21a. When the rack 20 moves along the arrow F, it drives the pinion 21 which drives the pinion 21a which rotates clockwise and drives the pinion 24 in the counterclockwise direction: while the pinion 22 rotates without driving the pinion 22a . When the rack 20 moves in the opposite direction to the arrow F, the pinion 22 drives the pinion 22a which rotates counterclockwise and meshes with an intermediate pinion 23, so that the pinion 24 is driven in the same direction counter-clockwise; the pinion 21 turning without driving the pinion 21a.
Ainsi, les mouvements de translation en sens contraires du piston de la pompe 13 sont transformés en un mouvement rotatif de l'arbre 25, solidaire du pignon 24, toujours dans le même sens de rotation. Les pignons 21 et 22 étant identiques, la vitesse de rotation de l'arbre 25 est identique dans les deux ses de translation de la crémaillère. Thus, the translation movements in opposite directions of the piston of the pump 13 are transformed into a rotary movement of the shaft 25, integral with the pinion 24, always in the same direction of rotation. Since the pinions 21 and 22 are identical, the rotational speed of the shaft 25 is identical in both translation teeth of the rack.
Le mécanisme de transformation T est doté d'un système de guidage linéaire tel que sur la Figure 6. Ce système est solidaire du moteur et de la pompe 13 par l'intermédiaire d'un carter. The transformation mechanism T is provided with a linear guide system as in Figure 6. This system is integral with the motor and the pump 13 via a housing.
Le piston du moteur et sa liaison avec la pompe sont soumis à un effort de flambage et à un jeu au niveau des joints. La crémaillère, entraînée par la tige du piston, doit donc être positionnée précisément pour engrener correctement les pignons 21 et 22. The piston of the motor and its connection with the pump are subjected to a buckling force and a clearance at the joints. The rack, driven by the piston rod, must be positioned precisely to properly mesh the pinions 21 and 22.
Sur la figure 4, le mécanisme de transformation du mouvement linéaire alterné en un mouvement rotatif en sens constant de la figure 3, est désigné par la 15 référence T. Sur cette figure, on voit que l'arbre 25 de sortie du mécanisme de transformation T pénètre dans un variateur V. L'arbre de sortie 26 du variateur V entraîne une pompe à engrenages E qui puise le produit dans un réservoir 27 et le refoule vers la buse d'application par la conduite 28. In FIG. 4, the mechanism for transforming the alternating linear motion into a constant rotary motion of FIG. 3 is designated by the reference T. In this figure, it can be seen that the output shaft of the transformation mechanism T enters a variator V. The output shaft 26 of the variator V drives a gear pump E which draws the product into a reservoir 27 and delivers it to the applicator nozzle via line 28.
Il est à noter que la pompe E, à engrenages peut être une pompe péristaltique. It should be noted that the pump E, gear can be a peristaltic pump.
Le variateur V peut être tout type de variateur mécanique connu, par exemple le variateur portant la marque ZERO-MAX de la société UNICUM ou encore un variateur à courroies. The variator V can be any type of known mechanical variator, for example the drive bearing the ZERO-MAX mark of UNICUM or a belt drive.
Il en résulte que c'est la pompe à piston 13, pompant le produit A, qui entraîne la pompe à engrenages E pompant le produit B, la vitesse d'entraînement de l'axe 26 entraînant la pompe à engrenages E étant proportionnelle à la vitesse de la pompe 13, cette proportion étant modifiable à volonté au moyen du variateur de vitesse V. Dans un exemple de mise en oeuvre de l'invention, la pompe à piston délivre 30 à 300 bars le produit A jusqu'au pistolet d'application. Comme cette pompe se trouve à une distance importante environ 7 m de distance et que le produit A a une grande viscosité, la pression tombe à moins de 100 bars du fait des pertes de charge dans le conduit 17. As a result, it is the piston pump 13, pumping the product A, which drives the gear pump E pumping the product B, the driving speed of the shaft 26 driving the gear pump E being proportional to the speed of the pump 13, this proportion being modifiable at will by means of the variable speed controller V. In an exemplary implementation of the invention, the piston pump delivers 30 to 300 bar the product A up to the gun of application. Since this pump is at a considerable distance of about 7 m and the product A has a high viscosity, the pressure drops to less than 100 bar due to pressure drops in the pipe 17.
Cela permet d'associer à cette pompe à piston une pompe à engrenages, qui délivre un produit B plus liquide en petite quantité, avec une pression inférieure à 100 bars au niveau de la pompe; parce que les pertes de charge sont négligeables. This allows to associate with this piston pump a gear pump, which delivers a more liquid product B in a small amount, with a pressure lower than 100 bar at the pump; because the pressure drops are negligible.
On obtient ainsi un réglage précis, fiable et constant, du dosage du produit B par rapport au produit A, ce dosage pouvant être déterminé à volonté par l'utilisateur au moyen du variateur V. La figure 5 représente une version simplifiée (et plus économique) de la 10 transmission du mouvement de l'arbre 25 à l'arbre 26 d'entraînement de la pompe à engrenages E. Cette transmission est constituée de deux pignons 29 et 30, l'un, 29 solidaire en rotation de l'arbre 25 et l'autre, 30, solidaire en rotation de l'arbre 26. This gives a precise, reliable and constant adjustment of the dosage of the product B relative to the product A, this dosage can be determined at will by the user by means of the variator V. Figure 5 shows a simplified version (and more economical ) of the transmission of the movement of the shaft 25 to the drive shaft 26 of the gear pump E. This transmission consists of two pinions 29 and 30, one, 29 integral in rotation with the shaft 25 and the other, 30, integral in rotation with the shaft 26.
Le rapport des diamètres des pignons 29 et 30 détermine le rapport de la vitesse d'entraînement de l'arbre 26 par rapport à celle de l'arbre 25. The ratio of the diameters of the pinions 29 and 30 determines the ratio of the driving speed of the shaft 26 relative to that of the shaft 25.
Pour changer ce rapport, il suffit de changer les pignons 29 et 30. To change this ratio, simply change the gears 29 and 30.
Il est également possible, comme cela est représenté en pointillés aux figures 4 et 5, d'ajouter aux produits A et B un troisième produit C (un colorant par exemple), en entraînant une deuxième pompe à engrenages E'. It is also possible, as shown in dashed lines in FIGS. 4 and 5, to add to the products A and B a third product C (a dye for example), by driving a second gear pump E '.
Dans le cas de la figure 4, une dérivation est prise sur l'arbre 26 de sortie du variateur V; dans le cas de la figure 5, un pignon additionnel 31, entraînant une pompe à engrenages E' est associé au pignon moteur 29. In the case of Figure 4, a bypass is taken on the output shaft 26 of the variator V; in the case of FIG. 5, an additional gear 31 driving a gear pump E 'is associated with the driving pinion 29.
Il est bien évident que l'on peut disposer d'autres pompes à engrenages additionnelles telles que la pompe E' et donc ajouter autant de produits additionnels. It is obvious that one can have other additional gear pumps such as pump E 'and therefore add as many additional products.
Il est également possible d'associer un autre variateur ou même plusieurs à l'autre sortie 25 du transformateur mécanique de mouvement T. Une autre façon, très simple, de modifier le dosage du produit B par rapport au produit A, consiste à changer la pompe E. On voit donc que la disposition selon la présente invention, permet une très grande souplesse d'adaptation aux problèmes posés par l'utilisateur. It is also possible to associate another or several dimmers with the other output of the mechanical motion transformer T. Another very simple way of modifying the dosage of the product B with respect to the product A is to change the pump E. It is therefore seen that the arrangement according to the present invention, allows a very high flexibility of adaptation to the problems posed by the user.
Elle permet en outre, de supprimer les pompes de gavage 6 et 7 de la figure 1. It also makes it possible to eliminate the booster pumps 6 and 7 of FIG.
