Abstract

Device for adding a liquid adjuvant into a fluid stream (3) in controlled proportions, characterised in that it comprises a means for metering and for continuous addition of the said adjuvant. Application especially to adhesives and multicomponent resins.

Description

La presente invention a pour objet un dispositif pour l'adjonction d'un adjuvant liquide dans une veine fluide selon des proportions contrôlées. The present invention relates to a device for adding a liquid adjuvant to a fluid vein in controlled proportions.

L'invention sera décrite en référence aux colles et résines multi-composants, auxquelles on souhaite adjoindre un nième composant, tel q'un accélérateur de durcissage ou de polymérisation. The invention will be described with reference to multi-component adhesives and resins, to which it is desired to add an nth component, such as a hardening or polymerization accelerator.

On comprendra néanmoins que le dispositif n'est pas limité à ces applications. Dans ce cas précis, on ajoute un accélérateur (de 0,05 % à en poids ou en volume environ) en vue de réduire, de contrôler ou de modeler les temps de polymérisation. It will nevertheless be understood that the device is not limited to these applications. In this specific case, an accelerator (from 0.05% to by weight or by volume approximately) is added in order to reduce, control or model the polymerization times.

Des dispositifs de ce type ont déjà été proposés. Ils présentent cependant l'inconvénient d'être relativement lourds dans leur mise en oeuvre. Devices of this type have already been proposed. However, they have the disadvantage of being relatively heavy in their implementation.

La présente invention a pour objet de remédier à cet inconvénient en proposant un dispositif qui permette un meilleur contrôle du processus de mélange, une augmentation de productivité, avec une limitation des instruments connexes. The object of the present invention is to remedy this drawback by proposing a device which allows better control of the mixing process, an increase in productivity, with a limitation of the related instruments.

Conformément à l'invention, ce résultat est obtenu avec un dispositif pour l'adjonction d'un adjuvant liquide dans une veine fluide selon des proportions contrôlées, caractérisé en ce qu'il comporte un moyen pour le dosage et l'adjonction en continu dudit adjuvant. In accordance with the invention, this result is obtained with a device for adding a liquid adjuvant to a fluid vein in controlled proportions, characterized in that it comprises means for the metering and the continuous addition of said adjuvant.

De préférence, le moyen concerné sera une pompe à plusieurs pistons entrainée par un servo-moteur à courant continu. Preferably, the means concerned will be a pump with several pistons driven by a direct current servo motor.

On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif en référence à la figure unique annexée qui est une vue schématique d'un dispositif conforme à l'invention. The invention will be better understood using the description given below of an embodiment given by way of nonlimiting example with reference to the single appended figure which is a schematic view of a device in accordance to the invention.

Le dispositif selon l'invention, référencé (1), est disposé entre un reservoir (2) contenant le produit à distribuer et une veine fluide (3). I1 sera prévu entre la conduite (3) et le dispositif (1) des moyens anti-retour (4). De plus, la pression Pl régnant dans la veine fluide (3) sera inférieure à la pression P2 de la conduite d'injection (5). The device according to the invention, referenced (1), is arranged between a reservoir (2) containing the product to be dispensed and a fluid stream (3). I1 will be provided between the line (3) and the device (1) of the non-return means (4). In addition, the pressure Pl prevailing in the fluid stream (3) will be less than the pressure P2 of the injection pipe (5).

Pour apporter souplesse et performance à l'installation, il est monté un servo-moteur à courant continu pour entrainer la pompe. To provide flexibility and performance to the installation, a DC servo motor is mounted to drive the pump.

L'ensemble est piloté par une électronique dédiée à microprocesseur. The whole is controlled by dedicated electronic microprocessor.

L'asservissement s'effectue par un capteur de type codeur à impulsions (1 000 pts/tour) qui mesure la rotation de l'arbre de pompe en contrôlant et la vitesse (écart de temps entre les impulsions) et le déphasage angulaire (régulation de position). The control is carried out by a pulse encoder type sensor (1000 pts / revolution) which measures the rotation of the pump shaft by controlling the speed (time difference between the pulses) and the angular phase shift (regulation position).

Le moteur est bloqué en rotation pendant l'arrêt par un frein. The motor is locked in rotation during stop by a brake.

La chai ne cinématique est alors la suivante - un arbre moteur piloté en vitesse et en position par un processus de traitement - un arbre codeur dédie au captage de l'information destiné à l'asservissement du moteur - un rotor de pompe (arbre récepteur). The kinematic chain is then as follows - a motor shaft controlled in speed and in position by a processing process - an encoder shaft dedicated to capturing the information intended to control the motor - a pump rotor (receiving shaft) .

Ce dispositif est intégré dans une ligne fluide comme un composant capable de doser des "micro-quantités" d'un produit liquide tel que - accélérateur - catalyseur - durcisseur - colorant - adjuvant et autres... This device is integrated into a fluid line as a component capable of dosing "micro-quantities" of a liquid product such as - accelerator - catalyst - hardener - colorant - adjuvant and others ...

Les avantages sont les suivants - capacite à s'asservir à un processus externe par l'adjonction d'un capteur (type débit par exemple) dont l'information sera traitée par le processus de commande ; - qualité des asservissements permettant un parfait contrôle des consignes et des actions télécommandées.  The advantages are as follows - ability to be enslaved to an external process by the addition of a sensor (flow type for example) whose information will be processed by the control process; - quality of the controls allowing perfect control of instructions and remote-controlled actions.
