Description

La présente invention concerne un couteau pourvu de deux zones de coupe pour réaliser des opérations de coupe et d'ébavurage notamment utiles dans la fabrication et le montage des pare-brises feuilletés automobiles.The present invention relates to a knife provided with two cutting zones to perform cutting and deburring operations particularly useful in the manufacture and assembly of automotive laminated windshields.

Les pare-brises feuilletés sont généralement constitués de deux ou plusieurs verres simples ou trempés, collés entre eux par une ou plusieurs couches d'un intercalaire en matière plastique : le butyral de polyvinyle (P.V.B.).Laminated windshields generally consist of two or more simple or tempered glasses, glued together by one or more layers of a plastic interlayer: polyvinyl butyral (P.V.B.).

Le P.V.B. présente une bonne adhérence au verre et un taux d'allongement important avant déchirure ce qui le rend particulièrement adapté à la réalisation de pare brises.The P.V.B. has a good adhesion to glass and a high rate of elongation before tearing which makes it particularly suitable for producing windshields.

En outre, il confère au verre feuilleté sa résistance à l'impact.In addition, it gives the laminated glass its resistance to impact.

Lors d'un choc avec un corps étranger, le verre se fendille et l'intercalaire P.V.B. maintient les morceaux de verre en place, ce qui diminue le risque de coupure par éclats de verre.During a shock with a foreign body, the glass cracks and the insert P.V.B. keeps the pieces of glass in place, which reduces the risk of breakage by splinters of glass.

De plus, l'intercalaire en PVB absorbe l'énergie résiduelle du corps étranger ce qui l'empêche de traverser le pare-brise si l'impact n'est pas disproportionné.In addition, the PVB interlayer absorbs the residual energy of the foreign body which prevents it from crossing the windshield if the impact is not disproportionate.

L'assemblage des pare brises s'effectue en automatique ou semi-automatique. Les opérateurs superposent le verre et le P.V.B. en fonction de la composition désirée et réalisent un premier ébarbage du volume feuilleté avant l'entrée du pare brise dans un four de préchauffage.The windshields are assembled automatically or semi-automatically. Operators superimpose glass and P.V.B. depending on the desired composition and perform a first trimming of the laminated volume before the entrance of the windshield in a preheating furnace.

Une fois les couches du pare brise collées, un second ébarbage périphérique est nécessaire pour éliminer le P.V.B. excédentaire dû au fluage de ce matériau lors du passage au four.Once the layers of the windshield are glued, a second peripheral deburring is necessary to remove excess PVB due to the creep of this material during the oven.

Pour réaliser l'ébarbage, on connaît des couteaux dont le fil de la lame est accessible au fond d'une ouverture du corps du couteau comme décrit dans le document FR 2 702 987 A1 .To perform deburring, knives are known whose blade wire is accessible at the bottom of an opening of the knife body as described in document FR 2 702 987 A1 .

Lorsque la partie de l'intercalaire PVB dépassant de la périphérie du pare brise est large il est toutefois nécessaire de procéder à plusieurs raclages avec un tel couteau pour parfaitement ébavurer les chants du pare brise.When the portion of the PVB interlayer protruding from the periphery of the windshield is wide, it is however necessary to carry out several scrapings with such a knife to perfectly deburr the edges of the windshield.

Dans un tel cas les opérateurs utilisent parfois un second couteau avec une pointe pour d'abord réduire la largeur de l'intercalaire qui dépasse des chants du pare brise.In such a case, the operators sometimes use a second knife with a point to first reduce the width of the spacer that protrudes from the edges of the windshield.

La présente invention prévoit un couteau à double usage comportant un corps muni d'une première ouverture, d'accès au fil d'une lame et formant une partie d'outil d'ébarbage pour laquelle la partie de fil de la lame accessible est encadrée par des parois de garde, et muni d'une seconde ouverture, d'accès à la pointe de la lame en bout du couteau.The present invention provides a dual purpose knife having a body having a first opening, access to the wire of a blade and forming a portion of the deburring tool for which the portion of wire of the blade accessible is framed. by guard walls, and provided with a second opening, access to the tip of the blade at the end of the knife.

Le corps comporte avantageusement un logement pour la lame adapté pour permettre un coulissement de la lame entre une position reculée de sécurité pour laquelle la pointe de la lame reste à l'intérieur du corps et une position avancée pour laquelle la pointe de la lame dépasse du corps par la seconde ouverture.The body advantageously comprises a housing for the blade adapted to allow sliding of the blade between a retracted safety position for which the tip of the blade remains inside the body and an advanced position for which the tip of the blade protrudes from the body by the second opening.

Selon un mode de réalisation avantageux, le couteau comporte un porte lame muni d'un poussoir adapté pour pousser la lame depuis la position reculée de sécurité vers la position avancée.According to an advantageous embodiment, the knife comprises a blade holder provided with a pusher adapted to push the blade from the retracted security position to the advanced position.

Le couteau comporte préférablement un moyen de rappel de la lame dans la direction de la position reculée.The knife preferably comprises a return means of the blade in the direction of the retracted position.

Avantageusement, le couteau comporte un capot arrière amovible.Advantageously, the knife comprises a removable rear cover.

Selon un mode de réalisation particulier de l'invention, le couteau comporte un organe de butée mobile pour la lame, monté coulissant dans une partie arrière du couteau qui est avantageusement constituée par le capot arrière amovible.According to a particular embodiment of the invention, the knife comprises a movable abutment member for the blade, slidably mounted in a rear portion of the knife which is advantageously constituted by the removable rear cover.

L'organe de butée mobile est avantageusement adapté pour définir une pluralité de postions de butées arrières plus ou moins reculées pour la lame.The movable abutment member is advantageously adapted to define a plurality of positions of rear stops more or less remote for the blade.

La pluralité de positions de butées arrières est préférentiellement réalisée au moyen d'un dispositif de crantage entre l'organe de butée et le corps.The plurality of rear stop positions is preferably achieved by means of a notching device between the stop member and the body.

Selon un mode de réalisation préférentiel, le fil de la lame comporte un profil dentelé.According to a preferred embodiment, the wire of the blade has a serrated profile.

D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui suit d'un exemple de réalisation non limitatif de l'invention en référence aux dessins qui représentent:

en figure 1:
une première vue en perspective éclatée d'un couteau selon l'invention;
en figure 2:
une seconde vue en perspective éclaté du couteau de la figure 1 selon un autre angle;
en figure 3:
une vue en perspective depuis le haut du couteau de la figure 1;
aux figures 4A à 4C:
des vues de côté du couteau de la figure 1 selon trois positions de fonctionnement.
Other characteristics and advantages of the invention will be better understood on reading the following description of a nonlimiting exemplary embodiment of the invention with reference to the drawings which represent:
in Figure 1:
a first exploded perspective view of a knife according to the invention;
in figure 2:
a second exploded perspective view of the knife of the figure 1 from another angle;
in Figure 3:
a perspective view from the top of the knife of the figure 1 ;
in FIGS. 4A to 4C:
side views of the knife from the figure 1 in three operating positions.

La figure 1 représente en vue éclatée un couteau à double usage selon l'invention particulièrement adapté aux opérations de fabrication de pare brises feuilletés qui comporte un corps 1 formant dans une direction longitudinale une partie de préhension et une partie de coupe.The figure 1 is an exploded view of a dual-purpose knife according to the invention particularly suitable for operations of manufacturing laminated breezes which comprises a body 1 forming in a longitudinal direction a gripping portion and a cutting portion.

Le corps reçoit une lame 4 qui, selon l'exemple, s'insère dans le corps par l'arrière et se déplace selon la direction longitudinale dans le corps.The body receives a blade 4 which, according to the example, is inserted into the body from the rear and moves in the longitudinal direction in the body.

La partie de coupe du corps est munie d'une première ouverture 2, d'accès au fil 3 de la lame 4 pour former une partie d'outil d'ébarbage pour laquelle le fil de la lame accessible dans la première ouverture est encadrée par des parois de garde 5, 6 qui permettent de guider le couteau par rapport au chant du pare brise et d'ébarber la feuille de PVB prise en sandwich entre les feuilles de verre constituant les faces extérieure et intérieure du pare brise.The cutting portion of the body is provided with a first opening 2, access to the wire 3 of the blade 4 to form a portion of deburring tool for which the wire of the blade accessible in the first opening is surrounded by guard walls 5, 6 which guide the knife relative to the edge of the windshield and deburr the PVB sheet sandwiched between the glass sheets constituting the outer and inner faces of the windshield.

Selon l'invention la partie de coupe du couteau est munie d'une seconde ouverture 7 d'accès à la pointe 8 de la lame en bout du couteau, sous forme d'une fente à une extrémité avant du couteau.According to the invention the cutting portion of the knife is provided with a second opening 7 to access the tip 8 of the blade at the end of the knife, in the form of a slot at a front end of the knife.

Le corps 1 comporte un logement pour la lame adapté pour permettre un coulissement de la lame entre une position reculée de sécurité pour laquelle la pointe de la lame reste à l'intérieur du corps et une position avancée pour laquelle la pointe 8 de la lame dépasse du corps par la seconde ouverture 7.The body 1 comprises a housing for the blade adapted to allow sliding of the blade between a retracted safety position for which the tip of the blade remains inside the body and an advanced position for which the tip 8 of the blade exceeds of the body by the second opening 7.

La lame selon l'exemple est une lame monobloc.The blade according to the example is a one-piece blade.

Pour permettre un déplacement aisé de la lame, le couteau comporte un porte lame 9 sur lequel vient se fixer la partie arrière de la lame au moyen d'un bouton 16 disposé latéralement sur le porte lame qui vient s'insérer dans un logement 17 dans une partie arrière de la lame.To allow easy movement of the blade, the knife comprises a blade holder 9 on which is fixed the rear portion of the blade by means of a button 16 disposed laterally on the blade holder which is inserted into a housing 17 in a rear part of the blade.

Selon l'exemple, le bouton 16 et le logement 17 comportent des profils complémentaires retenant la lame angulairement.According to the example, the button 16 and the housing 17 comprise complementary profiles holding the blade angularly.

Le porte lame est muni d'un poussoir 10 adapté à pousser la lame depuis la position reculée de sécurité vers la position avancée.The blade holder is provided with a pusher 10 adapted to push the blade from the retracted security position to the advanced position.

Selon la figure 3, le poussoir 10 dépasse à l'extérieur du corps du couteau au travers d'une rainure 18 permettant le coulissement de la lame et du porte lame longitudinalement dans le corps de couteau.According to figure 3 , the pusher 10 protrudes outside the knife body through a groove 18 for sliding the blade and blade holder longitudinally in the knife body.

Pour permettre un retour automatique de la lame en position reculée dans laquelle la pointe 8 de la lame 4 est protégée dans le corps du couteau, ce dernier comporte un moyen de rappel 11 de la lame dans la direction de la position reculée.To allow automatic return of the blade in the retracted position in which the tip 8 of the blade 4 is protected in the body of the knife, the latter comprises a return means 11 of the blade in the direction of the retracted position.

Ce moyen de rappel représenté en figure 1 est un ressort qui s'accroche sur un premier tenon 19 sur le porte lame et s'accroche sur un second tenon 19' sur le corps et en particulier sur le capot arrière 12.This return means represented in figure 1 is a spring that clings to a first pin 19 on the blade holder and clings to a second pin 19 'on the body and in particular on the rear cover 12.

Pour recouvrir et protéger le couteau contre l'usure au niveau des flancs de la première ouverture, des capots 20, 21 sont fixés sur le corps par des systèmes boutons 22 insérables en force dans des logements 23 et/ou par collage.To cover and protect the knife against wear on the flanks of the first opening, covers 20, 21 are fixed on the body by button systems 22 insertable in force in housing 23 and / or by gluing.

Pour accéder à l'intérieur du couteau et monter l'ensemble lame/porte lame, le couteau comporte un capot arrière amovible 12.To access the inside of the knife and mount the blade / blade holder assembly, the knife has a removable back cover 12.

Un élément important du couteau est plus particulièrement représenté aux figures 2 et 3.An important element of the knife is more particularly represented in figures 2 and 3 .

Il consiste en un organe de butée mobile 13 pour la lame, monté coulissant dans une partie arrière du couteau opposée à la partie avant par laquelle sort la pointe de la lame.It consists of a movable abutment member 13 for the blade, slidably mounted in a rear portion of the knife opposite to the front portion through which the tip of the blade.

Dans le cadre de l'ébarbage, le fil 3 de la lame comporte un profil dentelé et ce profil dentelé dépasse de la première ouverture pour réaliser l'ébavurage.In the context of deburring, the wire 3 of the blade has a serrated profile and this serrated profile protrudes from the first opening to perform deburring.

En utilisation, le profil dentelé s'use et doit être remplacé.In use, the serrated profile wears out and needs to be replaced.

L'organe de butée mobile 13 permet le remplacement dans la fenêtre constituée par la première ouverture d'une partie usée du profil dentelé par une partie neuve du profil dentelé.The movable abutment member 13 allows the replacement in the window constituted by the first opening of a worn part of the serrated profile by a new part of the serrated profile.

Pour cela, l'organe de butée mobile 13 est adapté pour définir une pluralité de postions de butées arrières plus ou moins reculées pour la lame et comporte pour ce faire une tige 13a contre laquelle vient buter une face arrière d'appui du porte lame 9 vers l'arrière du couteau.For this, the movable abutment member 13 is adapted to define a plurality of rear stop positions more or less remote for the blade and comprises for this purpose a rod 13a against which abuts a rear support surface of the blade holder 9 towards the back of the knife.

L'organe de butée mobile comporte lui même un poussoir 24 accessible de l'extérieur du couteau comme représenté en figure 3.The movable abutment member itself has a pusher 24 accessible from the outside of the knife as shown in FIG. figure 3 .

Cette disposition revient à réaliser un dispositif à double curseur, le curseur arrière de l'organe de butée définissant une pluralités de positions de butée arrière qui permettent dans le cas du couteau selon l'exemple de déplacer la lame par rapport à la première ouverture d'accès au fil de la lame pour remplacer une partie de fil de lame usée par une partie neuve.This arrangement amounts to producing a device with a double slider, the rear slider of the stop member defining a plurality of rear stop positions which, in the case of the knife according to the example, enable the blade to be moved relative to the first opening of the slider. access to the blade wire to replace a portion of used blade wire with a new part.

La pluralité de positions de butées arrières est réalisée au moyen d'un dispositif de crantage 14, 15 entre l'organe de butée et une rainure 30 du couteau dans laquelle coulisse l'organe de butée comme représenté notamment aux figures 2 et 3.The plurality of rear stop positions is achieved by means of a notching device 14, 15 between the stop member and a groove 30 of the knife in which the stop member slides, as shown in particular in FIGS. figures 2 and 3 .

Selon l'exemple, la partie arrière du couteau recevant l'organe de butée mobile est constituée par le capot arrière amovible 12.According to the example, the rear part of the knife receiving the movable stop member is constituted by the removable rear cover 12.

L'utilisation du couteau est représentée aux figures 4A à 4C.The use of the knife is shown in Figures 4A to 4C .

En figure 4A, le couteau est en position de repos avec la pointe de la lame en retrait dans le corps du couteau et les curseurs formés par les poussoirs 10, 24 du porte lame et de l'organe de butée sont en position reculée.In Figure 4A , the knife is in the rest position with the tip of the blade recessed in the knife body and the sliders formed by the pushers 10, 24 of the blade holder and the stop member are in the retracted position.

Dans cette position le fil 3 de lame accessible correspond à une partie de l'avant de la lame.In this position the accessible blade wire 3 corresponds to part of the front of the blade.

En figure 4B, le poussoir 10 du porte lame est poussé vers l'avant et la pointe de la lame sort de l'ouverture 7 pour réaliser une opération de coupe.In Figure 4B , the pusher 10 of the blade holder is pushed forward and the tip of the blade out of the opening 7 to perform a cutting operation.

Selon la figure 4C, lorsque la partie de fil accessible dans la première ouverture est usée on déplace le curseur 24 de l'organe de butée d'un ou plusieurs crans vers l'avant pour permettre à une partie neuve de la lame de se trouver en face de la première ouverture.According to figure 4C when the portion of wire accessible in the first opening is worn, the slider 24 of the stop member is moved one or more notches forward to allow a new portion of the blade to be in front of the first opening.

Il est à noter que la course du curseur de l'organe de butée est limitée pour que la pointe de la lame ne dépasse en aucun cas du couteau sous l'action de ce curseur.It should be noted that the stroke of the slider of the abutment member is limited so that the tip of the blade does not exceed in any case the knife under the action of this slider.

La position permettant la sortie de la pointe de la lame correspond uniquement à une position de poussée du poussoir 10 au delà de la position de butée maximale vers l'avant du curseur 24.The position allowing the exit of the tip of the blade corresponds only to a pushing position of the pusher 10 beyond the maximum stop position towards the front of the slider 24.

Lorsque le curseur 24 est avancé, lorsque le poussoir 10 du porte lame recule pour revenir en position de repos arrière, il bute contre la tige de la butée arrière mobile pour arrêter la lame vers l'arrière et la partie de fil neuve se trouve en face de la première ouverture 2, la lame ne pouvant reculer jusqu'à revenir à la position pour laquelle la partie de fil usée se trouve dans la première ouverture 2.When the slider 24 is advanced, when the pusher 10 of the blade holder back to return to the rear rest position, it abuts against the rod of the mobile rear stop to stop the blade rearward and the new wire portion is in facing the first opening 2, the blade can not move back to the position for which the used wire portion is in the first opening 2.

L'invention n'est pas limitée par l'exemple représenté et englobe les variantes entrant dans le champ de protection des revendications.The invention is not limited by the example shown and encompasses the variants falling within the scope of protection of the claims.
