L'installation représentée à la Fig. 1 comporte un fût 1 formant réserve de produit visqueux thermoplastique 2, ledit fût étant disposé sur une table élévatrice 3.The installation shown in FIG. 1 has a drum 1 forming a reserve of viscous product thermoplastic 2, said drum being placed on a table lifting 3.

Le fût 1 est fermé par un plateau chauffant 4. La table élévatrice 3 agit sur le produit 2 et le plateau chauffant 4 au moyen d'un vérin hydraulique 5.Barrel 1 is closed by a heating plate 4. The lifting table 3 acts on product 2 and the platform heating 4 by means of a hydraulic cylinder 5.

Une pompe double effet 6 actionnée par un vérin hydraulique 7 à double tige 8 est montée sur le plateau 4.A double-acting pump 6 actuated by a jack hydraulic 7 with double rod 8 is mounted on the plate 4.

Le plateau chauffant 4 est relié par une conduite 9 à un moyen d'accumulation et de distribution 10 du produit 2. Des capteurs de niveau 11, 13, 12 sont placés au contact du fût 1 pour déterminer respectivement s'il est plein ou vide et s'il est nécessaire de le changer.The heating plate 4 is connected by a pipe 9 to a means of accumulation and distribution 10 of product 2. Level sensors 11, 13, 12 are placed at the barrel 1 contact to determine respectively if it is full or empty and if it needs to be changed.

Le moyen d'accumulation et de distribution 10 est alimenté en produit 2 provenant du fût 1 par la conduite d'amenée rigide 9 munie d'un clapet anti-retour 15.The means of accumulation and distribution 10 is supplied with product 2 from barrel 1 through the pipe rigid inlet 9 fitted with a non-return valve 15.

Le moyen d'accumulation et de distribution 10 est relié à un dispositif mixeur 16 situé en aval et comprenant un récipient étanche 17 muni d'un conduit d'amenée rigide 18 du produit visqueux 2, d'un conduit d'amenée 19 d'azote 20 et d'un orifice de sortie 21. Le récipient 17 contient un agitateur 22.The means of accumulation and distribution 10 is connected to a mixer device 16 located downstream and comprising a sealed container 17 provided with a supply conduit rigid 18 of the viscous product 2, of a supply duct 19 nitrogen 20 and an outlet 21. The container 17 contains an agitator 22.

Un conduit 25 relie la sortie 21 du dispositif mixeur 16 à un organe de distribution 24, constitué par exemple d'un pistolet comportant une buse d'extrusion 26. L'azote 20 est contenu dans une bouteille 27 associée à un surpresseur 42, lui-même relié à une chambre d'injection 28 placée en amont du conduit d'amenée 19.A conduit 25 connects the output 21 of the device mixer 16 to a distribution member 24, consisting of example of a gun with an extrusion nozzle 26. The nitrogen 20 is contained in a bottle 27 associated with a booster 42, itself connected to an injection chamber 28 placed upstream of the supply duct 19.

Le moyen d'accumulation et de distribution 10 représenté à la Fig. 2 comporte une pièce usinée 29 formant une chemise, traversée par une canalisation débouchante 30 placée en continuité dans le circuit d'alimentation, et de diamètre, à l'entrée et à la sortie, identique au diamètre intérieur des conduites d'amenée 9 et de sortie 18. Une chambre 31, de diamètre supérieur à celui de la canalisation 30, débouche dans la canalisation 30, perpendiculairement à celle-ci. Cette chambre 31 comprend un piston plongeur 32, d'axe également perpendiculaire à celui de la canalisation 30, affleurant la canalisation 30 en position repos ou rentrée et apte à s'éloigner de ladite canalisation 30 pour générer un volume d'accumulation de produit 2. L'étanchéité de la chambre 31 est assurée par un presse-étoupe 33 placé entre la pièce usinée 29 et le piston plongeur 32. La chemise 29 comporte une résistance chauffante, non représentée, pour le maintien en température du produit 2.The means of accumulation and distribution 10 shown in Fig. 2 comprises a machined part 29 forming a jacket, crossed by a through pipe 30 placed in continuity in the supply circuit, and diameter, at the inlet and at the outlet, identical to the diameter inside the supply and outlet lines 18. An chamber 31, of diameter greater than that of the line 30, opens into line 30, perpendicular to it. This room 31 includes a plunger 32, with an axis also perpendicular to that of line 30, flush with line 30 in rest or retracted position and able to move away from said line 30 to generate an accumulation volume of product 2. The tightness of the chamber 31 is ensured by a cable gland 33 placed between the machined part 29 and the plunger 32. The jacket 29 includes a resistor heater, not shown, for maintaining product temperature 2.

The accumulation and distribution means 10 comprises two sensors 35, 36 for respective re-entry and exit positions of the plunger 32.

Le vérin 34 est actionné par un fluide F commandé par un distributeur 37, oui provoque le déplacement du piston plongeur 32 lors de l'actionnement du capteur 12 de niveau de remplacement du réservoir 1 jusqu'au capteur 36 de position sortie du piston 32, oui agit sur un moyen d'information pour l'autorisation du changement de réservoir 1.The cylinder 34 is actuated by a fluid F controlled by a distributor 37, yes causes the displacement of the plunger 32 when the sensor 12 is actuated replacement level from tank 1 to sensor 36 of position output from piston 32, yes acts on a means for authorization to change tank 1.

Comme représenté à la Fig. 3, la canalisation 30 assure la continuité du déplacement du produit 2 par un agrandissement progressif jusqu'à la dimension du diamètre de la chambre 31, de manière à éviter les zones où le produit pourrait stagner.As shown in Fig. 3, line 30 ensures the continuity of movement of product 2 by a progressive enlargement up to the diameter dimension of chamber 31, so as to avoid the areas where the product could stagnate.

Le fonctionnement de l'installation est le suivant.The operation of the installation is as follows.

Le fût 1 est déposé et centré sur la table élévatrice 3 qui maintient en contact le produit 2 et le plateau 4 avec une force constante grâce au vérin 7. Le produit 2, mis en pression dans la conduite 9 par la pompe 6, est directement admis dans le moyen d'accumulation et de distribution 10. Depuis le moyen 10, le produit alimente ensuite le dispositif mixeur 16.Barrel 1 is placed and centered on the table lift 3 which keeps product 2 and the plate 4 with constant force thanks to the jack 7. The product 2, pressurized in line 9 by the pump 6, is directly admitted into the means of accumulation and distribution 10. Since means 10, the product then supplies the mixer device 16.

L'azote 20 provenant de la bouteille 27 est admis dans le surpresseur hydropneumatique 42 qui élève la pression à environ 300 bars. L'azote sous pression est introduit dans le dispositif mixeur 16 par le conduit d'amenée 19, après traversée de la chambre d'injection 28. Par un mouvement de l'agitateur 22 dans le récipient 17, le produit 2 et l'azote 20 sont mélangés pour former le matériau à distribuer, qui quitte le dispositif mixeur 16 par l'orifice de sortie 21. Sous l'effet de la température et de la pression, ledit matériau est acheminé par le conduit 25 jusqu'au pistolet 24 qui l'extrude pour former par exemple un joint d'étanchéité sur une pièce quelconque à laquelle il adhère.Nitrogen 20 from bottle 27 is admitted in the hydropneumatic booster 42 which raises the pressure around 300 bar. Nitrogen under pressure is introduced into the mixing device 16 through the conduit inlet 19, after crossing the injection chamber 28. By a movement of the agitator 22 in the container 17, the product 2 and nitrogen 20 are mixed to form the material to be dispensed, which leaves the mixing device 16 through outlet 21. Under the effect of temperature and pressure, said material is conveyed by the leads 25 to the gun 24 which extrudes it to form for example a seal on any part to which it adheres.

Lorsque le produit 2 sort du fût 1, le niveau diminue. Dès que le niveau de produit 2 est bas, le capteur 12 est déclenché, indiquant à l'opérateur que le fût doit être changé.When product 2 leaves barrel 1, the level decreases. As soon as product level 2 is low, the sensor 12 is triggered, indicating to the operator that the barrel must be changed.

Ce capteur commande le déplacement, depuis sa position rentrée dans la chambre 31, du piston plongeur 32 au moyen du vérin 34 et du distributeur 37, jusqu'au déclenchement du capteur de position sortie 36 du piston 32. La chambre 31 est alors remplie de produit 2, ce remplissage s'effectuant à pression constante, sous l'action de la pompe 6, avec une perte de charge aussi faible que possible. Ainsi, l'alimentation du pistolet 24 en produit 2 n'est pas perturbée.This sensor controls the movement, from its retracted position in chamber 31, of the plunger 32 by means of the jack 34 and the distributor 37, up to triggering of the output position 36 sensor piston 32. Chamber 31 is then filled with product 2, which filling at constant pressure, under the action of pump 6, also with a pressure drop as low as possible. Thus, the power of the gun 24 in product 2 is not disturbed.

La chambre étant pleine de produit 2, le manipulateur ou l'opérateur déclenche la distribution du produit 2 en diminuant le volume de la chambre 31 grâce à la rentrée du piston plongeur 32. Tout le produit contenu dans la chambre 31 est distribué vers le dispositif mixeur 16, car il ne peut pas remonter en direction du fût 1 à cause du clapet anti-retour 15 placé directement en amont du moyen d'accumulation et de distribution 10 pour éviter des retours de produit 2 lors du fonctionnement dudit moyen. Le clapet 15 assure la sécurité du manipulateur qui change le fût 1. Pendant ce changement, la distribution de produit 2 continue.The chamber being full of product 2, the manipulator or the operator triggers the distribution of product 2 by reducing the volume of chamber 31 thanks to re-entry of the plunger 32. All the product contained in room 31 is distributed to the device mixer 16, because it cannot go up towards the barrel 1 because of the non-return valve 15 placed directly in upstream of the accumulation and distribution means 10 for avoid product returns 2 during operation said means. The valve 15 ensures the safety of the manipulator which changes the barrel 1. During this change, the distribution of product 2 continues.
