A threaded rod (42) has opposite hands cooperating with a threaded bushing (32) such that translation of the armature produced by the actuator drives contra-rotating movement of the rods. Free wheels (44) are integrated in rotation of the rods such that a hollow rod (12) equipped with an injection head and mixture is driven in same rotation direction by an intermediary plate (23) of the wheels.

Description

La présente invention a pour objet un mélangeur automatique destiné à l'injection et au mélange d'un agent accélérateur dans une cartouche de mastic contenant un agent de base.The present invention relates to an automatic mixer for injecting and mixing an accelerating agent in a sealant cartridge containing a base agent.

On connaît du Brevet EP 1264640 un procédé de mélange dans lequel il y a rotation d'une tête de mélange et d'injection, aussi bien lors de l'injection que du mélange, avec mouvement de va-et-vient de la cartouche.Patent is known EP 1264640 a mixing process in which there is rotation of a mixing and injection head, both during the injection and the mixture, with reciprocating movement of the cartridge.

Les Brevets US 6213631 et US 3737900 décrivent par contre une technique selon laquelle la rotation de la tête n'a lieu que pendant le mélange et non pendant l'injection.Licences US 6213631 and US 3737900 describe a technique according to which the rotation of the head takes place only during the mixing and not during the injection.

Aucun des documents ne décrit de machine automatique apte à mettre en oeuvre un tel mélange.None of the documents describes an automatic machine capable of implementing such a mixture.

Un mélangeur automatique est seulement connu du modèle d'Utilité Allemand DE 29708716 . Un moteur pneumatique assure la rotation de la tête de mélange, alors qu'un vérin pneumatique assure le mouvement de va-et-vient de la cartouche.An automatic mixer is only known from the German Utility model DE 29708716 . A pneumatic motor ensures the rotation of the mixing head, while a pneumatic cylinder ensures the movement of the cartridge back and forth.

Ce mélangeur est peu pratique quant à sa mise en oeuvre par un opérateur, notamment quant à la mise en place de la cartouche.This mixer is impractical for its implementation by an operator, especially as to the introduction of the cartridge.

La présente invention concerne un mélangeur automatique destiné à l'injection et au mélange d'un agent accélérateur dans une cartouche de mastic contenant un agent de base, l'agent accélérateur étant contenu dans une tige creuse équipée d'une tête d'injection et de mélange, caractérisé en ce qu'il comporte :

  • un vérin linéaire entraînant un équipage mobile comprenant d'une part, un dispositif de maintien du corps d'une cartouche de mastic pour imprimer un mouvement de va-et-vient au corps de la cartouche, et d'autre part, deux douilles filetées montées en inverse,
  • deux tiges filetées ayant des pas opposés coopérant fonctionnellement avec les douilles filetées de manière que la translation de l'équipage mobile produite par le vérin linéaire entraîne un mouvement contra-rotatif des deux tiges filetées,
  • deux roues libres qui sont solidaires en rotation des deux tiges filetées de sorte que la tige creuse équipée de la tête d'injection et de mélange soit entraînée dans un même sens de rotation par l'intermédiaire des roues libres.
The present invention relates to an automatic mixer for injecting and mixing an accelerating agent into a base-containing mastic cartridge, the accelerating agent being contained in a hollow rod equipped with an injection head and mixture, characterized in that it comprises:
  • a linear actuator driving a mobile unit comprising firstly, a device for holding the body of a cartridge of putty to print a reciprocating movement to the body of the cartridge, and secondly, two threaded bushings mounted in reverse,
  • two threaded rods having opposing steps cooperating functionally with the threaded bushes so that the translation of the moving element produced by the linear actuator causes a counter-rotating movement of the two threaded rods,
  • two freewheels which are integral in rotation of the two threaded rods so that the hollow rod equipped with the injection head and mixing is driven in the same direction of rotation by means of the freewheels.

Le mélangeur comporte une tige d'injection comprenant une tête d'injection apte à chasser le produit contenu dans la tige creuse.The mixer comprises an injection rod comprising an injection head capable of driving the product contained in the hollow rod.

Préférentiellement, le mélangeur présente un embrayage qui permet la rotation de la tête d'injection seulement lorsque la tige d'injection est en position rétractée.Preferably, the mixer has a clutch which allows the rotation of the injection head only when the injection rod is in the retracted position.

De la sorte, lors de l'injection, il n'y a pas de mouvement de rotation, mais seulement un déplacement relatif de va-et-vient.In this way, during the injection, there is no rotational movement, but only a relative back-and-forth movement.

Les douilles filetées sont avantageusement des douilles à billes dont les billes circulent dans des gorges des tiges filetées, ce qui permet d'éviter des à-coups de rotation lors des changements de sens de translation qui interviennent dans le mouvement de va-et-vient.The threaded bushings are advantageously ball bushings whose balls circulate in grooves of the threaded rods, which makes it possible to avoid jolts of rotation during the changes of direction of translation which intervene in the movement of back and forth .

Le vérin linéaire est avantageusement un vérin à guidage linéaire dépourvu de tige. La tige d'injection peut être couplée à un vérin d'injection assurant son déplacement en translation, notamment par l'intermédiaire d'une bielle.The linear jack is advantageously a linear guide cylinder devoid of rod. The injection rod may be coupled to an injection cylinder ensuring its displacement in translation, in particular by means of a connecting rod.

Le couplage en rotation entre les deux roues libres et la tige d'injection équipée de la tête d'injection et de mélange peut être assuré notamment par une roulette ou bien une courroie.The coupling in rotation between the two free wheels and the injection rod equipped with the injection head and mixing can be provided in particular by a wheel or a belt.

Le mélangeur automatique a pour fonction de réaliser automatiquement l'injection du durcisseur dans une cartouche de mastic puis un mélange selon les exigences du produit.The automatic mixer has the function of automatically injecting the hardener into a sealant cartridge and then mixing according to the product requirements.

Le mélangeur (voir figures 1 a et 1b) est prévu pour une cartouche 1 ayant un corps de cartouche 11 contenant le produit de base et une tige creuse 12 contenant le durcisseur à injecter, la tige creuse se terminant par une tête mélangeuse. Des cartouches de ce type sont représentées dans les documents cités.The mixer (see figures 1 a and 1b) is provided for a cartridge 1 having a cartridge body 11 containing the base product and a hollow rod 12 containing the hardener to be injected, the hollow rod terminating in a mixing head. Cartridges of this type are shown in the documents cited.

La machine comporte un boîtier 2 présentant au moins deux plateaux supérieurs 22 et médian 23, et un support au sol 25. Le corps 11 de la cartouche est maintenu par encliquetage dans un élément de maintien 30 qui fait partie d'un équipage mobile 3 qui porte également deux douilles filetées 31 et 32 coopérant avec deux tiges filetées 41 et 42 dont l'une a un pas à droite et l'autre un pas à gauche.The machine comprises a housing 2 having at least two upper plates 22 and a median 23, and a floor support 25. The body 11 of the cartridge is held by snapping into a holding element 30 which is part of a moving assembly 3 which also carries two threaded bushings 31 and 32 cooperating with two threaded rods 41 and 42, one of which has a step to the right and the other a step to the left.

Les douilles filetées 31 et 32 à pas inverses présentent avantageusement une cage à billes 43 dont les billes 44 circulent dans des gorges 45 des tiges filetées 41 et 42 à pas inverses (figure 2c).Threaded bushings 31 and 32 with opposite pitch advantageously have a ball cage 43 whose balls 44 circulate in grooves 45 of threaded rods 41 and 42 with opposite pitch ( Figure 2c ).

La tête 14 située à l'extrémité de la tige 12 est en prise avec la tête de rotation 65.The head 14 located at the end of the rod 12 is engaged with the rotation head 65.

Le vérin linéaire 4 assure le déplacement de l'équipage mobile 3, c'est-à-dire d'une part, le déplacement du corps de cartouche 11 relativement à la tige 12 et d'autre part, la mise en rotation dans des sens opposés des tiges filetées 41 et 42.The linear jack 4 ensures the displacement of the moving assembly 3, that is to say on the one hand, the displacement of the cartridge body 11 relative to the rod 12 and, on the other hand, the rotation in opposite directions of the threaded rods 41 and 42.

La fonction de ces tiges filetées est de transformer le mouvement de translation en va-et-vient de l'équipage mobile 3 en un mouvement de rotation de la tige 12 et donc de sa tête mélangeuse toujours dans le même sens de rotation, pour assurer le mélange.The function of these threaded rods is to transform the translation movement back and forth of the mobile assembly 3 into a rotational movement of the rod 12 and thus of its mixing head always in the same direction of rotation, to ensure The mixture.

A cet effet, l'extrémité des tiges filetées 41 et 42 porte sous le plateau intermédiaire 23, des roues libres 43 et 44 aptes à transmettre un couple de rotation toujours dans le même sens.For this purpose, the end of the threaded rods 41 and 42 carries under the intermediate plate 23, freewheels 43 and 44 able to transmit a rotation torque always in the same direction.

Par exemple, lors de la translation vers le haut de l'équipage mobile 3, les tiges filetées contra-rotatives 41 et 42 entraînent la roue libre 43 dans le sens de la flèche F1, et la roue libre 44 dans le sens de la flèche F2. Dans cette configuration, la roue libre 43 transmet le couple généré par la tige filetée 42 et la roue libre 43 tourne à vide. La tige 12 est alors entraînée dans le sens de la flèche F, par l'intermédiaire de la poulie intermédiaire 45.For example, during the upward translation of the moving assembly 3, the counter-rotating threaded rods 41 and 42 drive the freewheel 43 in the direction of the arrow F 1 , and the free wheel 44 in the direction of the arrow F 2 . In this configuration, the freewheel 43 transmits the torque generated by the threaded rod 42 and the free wheel 43 rotates empty. The rod 12 is then driven in the direction of the arrow F, via the intermediate pulley 45.

Lors de la translation vers le bas de l'équipage mobile 3, la roue libre 44 tourne à vide dans le sens opposé à la flèche F2 et la roue libre 43 tourne dans le sens opposé à la flèche F1 et transmet le couple généré par la tige filetée 42. Là encore, la tige 12 est entraînée en rotation dans le sens de la flèche F.During the downward translation of the moving element 3, the freewheel 44 rotates idly in the opposite direction to the arrow F 2 and the freewheel 43 rotates in the opposite direction to the arrow F 1 and transmits the generated torque by the threaded rod 42. Again, the rod 12 is rotated in the direction of the arrow F.

La mise en oeuvre de douilles à billes (figure 2c) permet d'éviter des à-coups lors de l'inversion du mouvement, un grand nombre de mouvement de va-et-vient (jusqu'à 70) s'avérant en général nécessaire pour assurer un bon mélange.The use of ball bushings ( Figure 2c ) allows to avoid jolts during the inversion of the movement, a large number of back and forth movement (up to 70) being generally necessary to ensure a good mixture.

Une tige d'injection 54 se terminant par une tête 55 est commandée par un vérin avec une reprise par une bielle 53 qui permet de renvoyer et d'amplifier le débattement. Le déplacement de la tige 54 a pour effet que sa tête 55 (fig. 2d) chasse le produit durcisseur 15 qui est contenu dans la tige creuse 12.An injection rod 54 ending in a head 55 is controlled by a jack with a recovery by a connecting rod 53 which allows to return and amplify the deflection. The displacement of the rod 54 has the effect that its head 55 ( Fig. 2d ) expels the hardener product 15 which is contained in the hollow rod 12.

Cette opération d'injection s'effectue en soumettant le corps de la cartouche 11 à un mouvement de va-et-vient par déplacement de l'équipage mobile 3 et en déplaçant progressivement la tige 54 pour chasser le produit 15.This injection operation is carried out by subjecting the body of the cartridge 11 to a movement back and forth by displacement of the moving assembly 3 and progressively moving the rod 54 to expel the product 15.

Comme on l'a vu, le déplacement de l'équipage mobile entraîne également la rotation de la tige creuse 12 et donc de la tête d'injection et de mélange située à son extrémité.As we have seen, the displacement of the moving element also causes the rotation of the hollow rod 12 and therefore of the injection and mixing head located at its end.

Préférentiellement, et comme représenté à la figure 2d, on prévoit de débrayer la rotation de la tige creuse 12 au cours de l'injection de sorte que :

  • l'injection s'effectue avec seulement un mouvement de translation du corps de cartouche 11 par rapport à la tige 12, et un mouvement de translation de la tige d'injection 54.
  • le mélange s'effectue avec un mouvement combiné de translation dû au va-et-vient de l'équipage mobile 3 qui entraîne le corps de cartouche 11 et de rotation de la tige creuse 12 et donc de la tête de mélange et d'injection.
Preferably, and as shown in figure 2d , it is planned to disengage the rotation of the hollow rod 12 during the injection so that:
  • the injection is carried out with only a translational movement of the cartridge body 11 with respect to the rod 12, and a translational movement of the injection rod 54.
  • the mixing is carried out with a combined movement of translation due to the comings and goings of the moving element 3 which drives the cartridge body 11 and the rotation of the hollow rod 12 and thus of the mixing and injection head .

Cette fonction de débrayage est illustrée à la figure 2d.This disengagement function is illustrated in figure 2d .

En la position rétractée qui est représentée, la tête 55 est en butée arrière sur un épaulement 66 de la broche de rotation 65, avec laquelle la tête 14 de la tige 12 est en prise. Dans cette position, les deux parties 62 et 63 de l'embrayage 61 sont en prise. Lorsque la tige d'injection 54 est actionnée, la tête 55 s'écarte de l'épaulement 66 et les deux parties 62 et 63 s'écartent l'une de l'autre, d'où un débrayage de la fonction de rotation.In the retracted position which is shown, the head 55 is in rear abutment on a shoulder 66 of the rotational pin 65, with which the head 14 of the rod 12 is engaged. In this position, the two parts 62 and 63 of the clutch 61 are engaged. When the injection rod 54 is actuated, the head 55 deviates from the shoulder 66 and the two parts 62 and 63 deviate from one another, hence a disengagement of the rotation function.

Avec la suppression du mouvement de rotation lors de l'injection, on évite le blocage de la valve d'injection de l'accélérateur responsable de l'éclatement des tiges.With the suppression of the rotational movement during the injection, it prevents the blockage of the injection valve of the accelerator responsible for the bursting of the rods.

Par ailleurs, la mise en oeuvre d'un vérin 52 à simple effet permet d'assurer la rentrée de la tige d'injection 54 lors de l'arrêt de la pression d'air. Le vérin 52 est avantageusement couplé à une vanne de surpression qui permet de détecter la montée de pression en fin de course et de déclencher la phase de mélange.Furthermore, the implementation of a cylinder 52 single-acting ensures the retraction of the injection rod 54 when stopping the air pressure. The jack 52 is advantageously coupled to a pressure relief valve which makes it possible to detect the rise in pressure at the end of the stroke and to trigger the mixing phase.

La figure 3 montre le montage de l'équipage mobile 3, du vérin 4 et des tiges filetées 41 et 42 entre le plateau supérieur 22 et le plateau inférieur 23. Un ressort 33 permet le maintien de la cartouche après sa mise en place. Une poignée 35 permet de déplacer l'équipage mobile 3 lors de la mise en place de la cartouche.The figure 3 shows the mounting of the moving assembly 3, the cylinder 4 and threaded rods 41 and 42 between the upper plate 22 and the lower plate 23. A spring 33 allows the maintenance of the cartridge after its introduction. A handle 35 makes it possible to move the moving assembly 3 during the positioning of the cartridge.

Le mécanisme de renvoi de la rotation entre les tiges filetées 41 et 42 et la tige de la cartouche est monté sur un deuxième plateau intermédiaire 24 situé sous le plateau 23.The mechanism for returning the rotation between the threaded rods 41 and 42 and the rod of the cartridge is mounted on a second intermediate plate 24 located under the plate 23.

L'ensemble est porté par un bâti présentant des montants verticaux arrière 71 et 72 reliés par des barres transversales 77 et 78, etdes montants verticaux avant 73 et 74. Les barres transversales 78 et 79 portent le plateau 24.
