Description
La présente invention est relative à la fabrication, la mise en place et la pose d'éléments de calage. The present invention relates to the manufacture, installation and installation of wedging elements.
Elle concerne en premier lieu un procédé pour fabriquer, mettre en place et poser de tels éléments, en particulier du type intercalaire. Lesdits éléments constituent des intercalaires pour des pièces réalisées en matériau non conducteur électriquement. It relates firstly to a method for manufacturing, installing and installing such elements, in particular of the interlayer type. Said elements constitute spacers for parts made of electrically non-conductive material.
On connaît comme éléments intercalaires des pastilles de liège sur lesquelles il a été collé un matériau adhésif sur une face. Ces pastilles présentent l'inconvénient d'être composé de deux matériaux. De plus, le liège ne peut être mis en forme qu'une seule fois. Known as intermediate elements are cork discs on which an adhesive material has been stuck on one side. These tablets have the drawback of being made of two materials. In addition, cork can only be shaped once.
En conséquence, elles ne sont pas recyclables après usure. En outre, l'automatisation de la fabrication est difficile. Consequently, they cannot be recycled after wear. In addition, manufacturing automation is difficult.
Pour remédier à ces inconvénients et obtenir une pièce adhésive sur une face, non adhésive sur la face opposée et recyclable, l'invention a pour objet un procédé de fabrication, de mise en place et de pose d'éléments réalisés en suivant les étapes successives suivantes
- remplir un réservoir d'un matériau thermofusible,
- fondre le matériau thermofusible,
- pomper le matériau thermofusible,
- extruder ledit matériau en contrôlant son débit
volumétrique,
- remplir avec dudit matériau thermofusible au moins
une empreinte de moule servant à former l'élément,
- marquer en bas-relief au moins une face de
l'élément,
- refroidir le matériau thermofusible de l'élément
pour le solidifier,
- démouler ledit élément,
- rendre liquide la face opposée à la face marquée
en bas-relief,
- appliquer la face liquide de l'élément pour le
faire adhérer par collage sur ladite pièce. To remedy these drawbacks and obtain an adhesive piece on one side, non-adhesive on the opposite side and recyclable, the invention relates to a process for manufacturing, installing and installing elements produced by following the successive steps. following
- fill a tank with a hot-melt material,
- melt the hot-melt material,
- pump the hot-melt material,
- extrude said material by controlling its flow
volumetric,
- fill with said hot-melt material at least
a mold imprint used to form the element,
- mark in bas-relief at least one side of
the element,
- cool the element's hot-melt material
to solidify it,
- unmolding said element,
- make liquid the opposite side to the marked side
in bas-relief,
- apply the liquid side of the element to
adhere by bonding to said part.
Dans le but de supprimer l'inertie et de contrôler l'épaisseur de fusion de la face rendue liquide, l'étape de liquéfaction de la face opposée à la face marquée est réalisée par apport de matériau thermofusible fondu. With the aim of eliminating the inertia and controlling the thickness of melting of the face made liquid, the step of liquefying the face opposite to the marked face is carried out by adding molten hot-melt material.
Suivant d'autres caractéristiques
- Le matériau thermofusible fondu est le même que
celui de l'élément ;
- L'étape de liquéfaction de la face opposée à la
face marquée est réalisée par chauffage
- Une dernière étape consiste à poser une autre
pièce sur la face marquée de l'élément solidaire
de la pièce précédente.According to other characteristics
- The molten hot-melt material is the same as
that of the element;
- The liquefaction step on the side opposite the
marked side is made by heating
- A final step is to ask another
part on the marked face of the integral element
from the previous play.
Pour permettre d'automatiser le procédé ci-dessus, l'invention a encore pour objet une installation du type comprenant un dispositif vide-fût recevant un réservoir de produit thermofusible, ledit réservoir étant relié à un pistolet volumétrique de pose de matériau thermofusible dans au moins une empreinte d'un moule, l'installation comportant au moins un moyen de marquage venant au contact du matériau dans l'empreinte, un moyen de refroidissement et un moyen de transfert pour sortir l'élément en vue de l'apporter au poste de réalisation de la face liquide. To allow the above process to be automated, the invention also relates to an installation of the type comprising a barrel emptying device receiving a tank of hot-melt product, said tank being connected to a volumetric spray gun for laying hot-melt material in the at least one imprint of a mold, the installation comprising at least one marking means coming into contact with the material in the imprint, a cooling means and a transfer means for removing the element in order to bring it to the station of the liquid side.
Suivant une autre caractéristique, l'installation comprend un moyen, en particulier une buse de dépose sur ledit élément refroidi d'une goutte de produit thermofusible liquide, ledit moyen de dépose relié au videfût étant situé en amont du pistolet volumétrique. According to another characteristic, the installation comprises a means, in particular a depositing nozzle on said element cooled with a drop of liquid hot-melt product, said depositing means connected to the barrel being located upstream of the volumetric gun.
L'invention a également pour objet un dispositif selon lequel le moule comporte au moins une deuxième empreinte de la forme d'un barreau permettant de fabriquer des barreaux de produit thermofusible destinés à alimenter un pistolet manuel de pose de produit liquide sur une face de l'élément. The invention also relates to a device according to which the mold comprises at least a second imprint in the form of a bar making it possible to manufacture bars of hot-melt product intended to supply a manual gun for placing liquid product on one side of the 'element.

Des vérins 66 ajustent le groupe de pompage 5 en fonction du niveau de la surface du produit thermofusible 4 contenu dans le fût 5. Le groupe de pompage 5 est relié par une tuyauterie 6 à un pistolet à engrenage 7 de distribution du produit chaud, c'est-à-dire sous forme liquide. The installation shown in FIG. 1 includes a barrel emptying device 1. This device 1 comprises a chassis 2 on which a tank or barrel 3 is placed filled with hot-melt product 4, a pumping group 5 is placed above the barrel 3. Cylinders 66 adjust the pumping group 5 as a function of the level of the surface of the hot-melt product 4 contained in the barrel 5. The pumping group 5 is connected by a pipe 6 to a gear gun 7 for distributing the hot product, that is to say say in liquid form.
Le pistolet 7 comprend un boîtier 8 délimité par six parois planes 9. Une paroi présente une ouverture d'alimentation 10 ; la paroi en vis-à-vis comporte un orifice de sortie 11 débouchant dans une buse 12. Un moteur électrique 13 commandé par un variateur électronique est fixé sur une paroi 9. The gun 7 comprises a housing 8 delimited by six flat walls 9. A wall has a supply opening 10; the facing wall has an outlet 11 opening into a nozzle 12. An electric motor 13 controlled by an electronic variator is fixed to a wall 9.
La buse 12 et le moteur 13 sont positionnés sur le boîtier 8 par l'intermédiaire d'un élément support chauffant 14. La tuyauterie 6 d'amenée de produit thermofusible 4 est liée à l'ouverture d'alimentation 10. The nozzle 12 and the motor 13 are positioned on the housing 8 by means of a heating support element 14. The piping 6 for supplying hot-melt product 4 is linked to the supply opening 10.
Une canalisation 15 relie l'orifice de sortie 11 à la buse 12. Deux prises de pression 16, 17 sont montées respectivement à l'ouverture d'alimentation 10 et à la sortie canalisation 15 dans la buse 12. La buse 12 comprend un orifice d'extrusion 18 conique creux obturable par une tige 19 formant clapet et solidaire d'un vérin de manoeuvre pneumatique 20.A line 15 connects the outlet orifice 11 to the nozzle 12. Two pressure taps 16, 17 are mounted respectively at the supply opening 10 and at the outlet line 15 in the nozzle 12. The nozzle 12 comprises an orifice extrusion 18 conical hollow closable by a rod 19 forming a valve and integral with a pneumatic actuator 20.
Le boîtier 8 contient un engrenage formé de deux pignons 21 et 22. Les pignons 21 et 22 parallèles entre eux sont montés perpendiculairement à l'orifice de sortie 11. The housing 8 contains a gear formed by two pinions 21 and 22. The pinions 21 and 22 which are parallel to each other are mounted perpendicular to the outlet orifice 11.
Le pistolet 7 alimente en produit une table d'indexage 23. La table 23 comprend des empreintes 24 pour le moulage et un moyen de refroidissement 25. La table 23 qui comprend un dispositif 26 de mise en mouvement pas à pas est circulaire comme le représente la Fig. 3 et les empreintes 24 sont disposées près du bord selon une trajectoire circulaire. Un pousseur 27 permet de former les empreintes 24. The gun 7 supplies product with an indexing table 23. The table 23 includes cavities 24 for molding and a cooling means 25. The table 23 which includes a device 26 for setting in motion step by step is circular as shown Fig. 3 and the imprints 24 are arranged near the edge along a circular trajectory. A pusher 27 makes it possible to form the imprints 24.
Le pistolet 7, le pousseur 27 et le préhenseur 28, tous étant mobiles par rapport à la surface 29 de la table 23, sont disposés au-dessus de la trajectoire des empreintes 24. The gun 7, the pusher 27 and the gripper 28, all of which are movable relative to the surface 29 of the table 23, are disposed above the path of the imprints 24.
L'installation selon l'invention comprend également un préhenseur 28 à ventouses 29 par aspiration d'air 30, comme le représente la Fig. 2. Le préhenseur 28 est manipulé par un robot 31 jusqu'à un mécanisme articulé 32 comportant un plateau 33 de réception de l'élément 34. Le plateau articulé 32 étant placé sous une buse d'extrusion 35 reliée à la tuyauterie 6. Un vérin 36 pousse le mécanisme 32 jusqu'à des volumes en verre empilés sur une palette 38. The installation according to the invention also comprises a gripper 28 with suction cups 29 by air suction 30, as shown in FIG. 2. The gripper 28 is manipulated by a robot 31 to an articulated mechanism 32 comprising a plate 33 for receiving the element 34. The articulated plate 32 being placed under an extrusion nozzle 35 connected to the piping 6. A jack 36 pushes mechanism 32 to glass volumes stacked on a pallet 38.
Le fonctionnement de l'installation est le suivant, le produit 4 est pompé dans le fût 3 par le groupe de pompage 5 qui alimente le pistolet 7 par le conduit 6. The operation of the installation is as follows, the product 4 is pumped into the barrel 3 by the pumping unit 5 which supplies the gun 7 through the conduit 6.
Le produit 4 est entraîné vers l'orifice d'extrusion 18 par la rotation des pignons 21, 22 de l'engrenage. Les pignons 21, 22 sont entraînés et contrôlés en rotation par le moteur, donc le moteur contrôle le débit. Le robot 31 donne l'autorisation de mise en route du moteur et d'ouverture de la buse quand le pistolet 7 est en position de travail au-dessus d'une empreinte 24, le produit s'écoule à débit régulé, ce qui permet d'obtenir le remplissage répétitif d'une empreinte. Puis la table d'indexage 23 tourne d'un pas de manière à amener l'empreinte 24 qui vient d'être remplie sous le pousseur 27 et l'empreinte suivante sous le pistolet 7. The product 4 is driven towards the extrusion orifice 18 by the rotation of the pinions 21, 22 of the gear. The pinions 21, 22 are driven and controlled in rotation by the motor, so the motor controls the flow. The robot 31 gives the authorization to start the engine and to open the nozzle when the gun 7 is in the working position above an imprint 24, the product flows at a regulated flow rate, which allows to obtain repetitive filling of an imprint. Then the indexing table 23 turns one step so as to bring the impression 24 which has just been filled under the pusher 27 and the following impression under the gun 7.
A ce moment le pousseur 27 dont la face d'appui peut être marquée, descend comme le représente la Fig. 4. Ce pousseur descend à l'affleurement de l'empreinte ou dans l'empreinte 24 représentée à la Fig. 5. Ensuite le pousseur se retire et l'élément chaud 39 représenté à la Fig. 6, est formé. Le cycle se termine par la fermeture de la buse et l'arrêt simultané du moteur commandé par le robot et de la table. At this moment the pusher 27, the bearing face of which can be marked, descends as shown in FIG. 4. This pusher descends to the level of the impression or in the impression 24 shown in FIG. 5. Then the pusher withdraws and the hot element 39 shown in FIG. 6, is formed. The cycle ends with the closure of the nozzle and the simultaneous stop of the motor controlled by the robot and the table.
Après plusieurs étapes du mouvement pas à pas de la table 23, les éléments refroidis sont sortis des empreintes 24 par le préhenseur 28 et apportés jusqu'à la buse 35 de dépose de produit liquide sur la face lisse de l'élément 34 ; puis le vérin 36 pousse jusqu'à collage de la face liquide l'élément 34 sur les volumes de verre. After several stages of the step-by-step movement of the table 23, the cooled elements are taken out of the cavities 24 by the gripper 28 and brought to the nozzle 35 for depositing liquid product on the smooth face of the element 34; then the jack 36 pushes until the liquid face sticks the element 34 on the glass volumes.
Le robot 31 positionne et déplace le préhenseur 28, le pousseur 27 et la buse 35. The robot 31 positions and moves the gripper 28, the pusher 27 and the nozzle 35.
En variante le fond de l'empreinte 24 est marqué en bas relief et le pousseur est lisse. As a variant, the bottom of the imprint 24 is marked in low relief and the pusher is smooth.
Dans une deuxième variante le dispositif vide-fût comporte un groupe de pompage 5 fixe et un fût mobile disposé sur une chaise élévatrice de manière conforme au modèle d'utilité allemand G 9420028.9 au nom de la
Demanderesse.In a second variant, the barrel emptying device comprises a fixed pumping group 5 and a movable barrel disposed on a lifting chair in accordance with the German utility model G 9420028.9 in the name of the
Applicant.
L'installation représentée à la Fig. 7 diffère de celle des Fig. 1 et 2 en ce qu'elle ne comporte pas de buse automatique de dépôt de produit liquide 4 sur les éléments 34, ni des moyens de transfert automatique de ces éléments sur les volumes 37. The installation shown in FIG. 7 differs from that of FIGS. 1 and 2 in that it does not include an automatic nozzle for depositing liquid product 4 on the elements 34, nor means for automatic transfer of these elements to the volumes 37.
Les références correspondantes à celles des figures précédentes ont été conservées sur la Fig. 7. The references corresponding to those of the preceding figures have been preserved in FIG. 7.
La table 23 comprend une empreinte circulaire très profonde 40 de manière à former un barreau de produit thermofusible. A la différence de l'installation précédente, l'installation de la Fig. 7 comprend une caisse 41 que le robot remplit d'éléments 34. La Fig. 8 représente un pistolet à colle 42 connu. Le barreau provenant de l'empreinte 40 est introduit dans le pistolet à colle 42, ce qui permet de déposer la face liquide sur les éléments 34 en faisant fondre l'extrémité du barreau. The table 23 includes a very deep circular imprint 40 so as to form a bar of hot-melt product. Unlike the previous installation, the installation in FIG. 7 comprises a box 41 which the robot fills with elements 34. FIG. 8 shows a known glue gun 42.
