Description

La présente invention concerne un dispositif adapté pour fragmenter le verre d'une fenêtre usagée et un procédé de fragmentation correspondant.The present invention relates to a device suitable for fragmenting the glass of a used window and a corresponding fragmentation method.

Le recyclage de fenêtre usagée est aujourd'hui une problématique de première importance, ayant notamment pour enjeux la diminution des coûts de matière première vitrifiable et la réduction de l'empreinte environnementale des nouvelles fenêtres. Un tel recyclage implique la séparation du verre des fenêtres usagées de leur cadre.The recycling of used windows is today a problem of prime importance, having in particular the challenges of reducing the cost of vitrifiable raw materials and reducing the environmental footprint of new windows. Such recycling involves separating used window glass from its frame.

Sont connus de l'état de la technique, dont le document EP0618011 (A1 ), des dispositifs de fragmentation du verre conçus à ces fins, qui comprennent un convoyeur adapté pour le transport à plat de fenêtres usagées et un ensemble de fragmentation surmontant ce convoyeur et étant adapté pour la fragmentation des fenêtres au cours de leur transport sur le convoyeur. Plus précisément, et tel qu'illustré par la Figure 1, qui fait référence au document EP0618011 (A1 ), un tel ensemble de fragmentation comprend une pluralité de couteaux agencés en rotation sur un disque qui est lui-même entraîné en rotation par un moteur. Chaque couteau est décalé par rapport au centre de ce disque. Lorsque ce disque est mis en rotation, ces lames viennent percuter la surface d'une fenêtre positionnée sur le convoyeur, provoquant ainsi la fragmentation du verre.Are known from the state of the art, including the document EP0618011 (A1 ), glass breaking devices designed for this purpose, which comprise a conveyor adapted for the flat transport of used windows and a breaking assembly surmounting this conveyor and being adapted for the breaking of the windows during their transport on the conveyor . More specifically, and as illustrated by the Figure 1 , which refers to the document EP0618011 (A1 ), such a fragmentation assembly comprises a plurality of knives arranged in rotation on a disk which is itself driven in rotation by a motor. Each knife is offset from the center of this disc. When this disc is set in rotation, these blades strike the surface of a window positioned on the conveyor, thus causing the fragmentation of the glass.

Un tel ensemble de fragmentation a au moins pour inconvénient d'engendrer une sollicitation mécanique importante tant des lames que de leur liaison avec le disque rotatif. En effet, lors de l'impact des lames sur le verre et/ou le cadre d'une fenêtre, une proportion importante de la force de réaction du verre, du cadre et éventuellement du support sur lequel la fenêtre repose, est répercutée sur toute la longueur de la lame, notamment sous la forme de contraintes en flexion, ainsi qu'au niveau de sa liaison avec le disque. Il y a donc un risque d'usure prématurée de la lame et/ou du disque rotatif. Afin de pallier cet inconvénient, et tel que décrit par le document EP0618011 (A1 ), il est envisagé d'adapter le convoyeur de sorte à ménager en dessous de la zone d'impact des lames des ouvertures permettant au verre fragmenté de traverser le convoyeur pour être collecté dans un bac dédié.Such a fragmentation assembly has at least the drawback of generating significant mechanical stress both on the blades and on their connection with the rotating disc. Indeed, during the impact of the slats on the glass and/or the frame of a window, a significant proportion of the reaction force of the glass, of the frame and possibly of the support on which the window rests, is passed on to all the length of the blade, in particular in the form of bending stresses, as well as at the level of its connection with the disc. There is therefore a risk of premature wear of the blade and/or of the rotating disc. In order to overcome this drawback, and as described by the document EP0618011 (A1 ), it is envisaged to adapt the conveyor so as to provide openings below the impact zone of the blades allowing the fragmented glass to pass through the conveyor to be collected in a dedicated bin.

Cette solution technique reste cependant très insatisfaisante au moins parce qu'elle implique une adaptation spécifique du convoyeur, excluant par exemple la mise en oeuvre d'un tapis de convoyage, et qu'elle ne permet pas de se prémunir d'une usure prématurée de l'ensemble de fragmentation, les couteaux pouvant éventuellement percuter un cadre de fenêtre qui offrirait une résistance anormalement importante.However, this technical solution remains very unsatisfactory, at least because it involves a specific adaptation of the conveyor, excluding for example the setting implementation of a conveyor belt, and that it does not make it possible to guard against premature wear of the fragmentation assembly, the knives possibly being able to strike a window frame which would offer an abnormally high resistance.

L'invention vise à répondre aux inconvénients décrits ci-dessus. Plus particulièrement, dans au moins un mode de réalisation, la technique proposée se rapporte à un dispositif de fragmentation adapté pour fragmenter le verre d'une fenêtre usagée, et comprenant au moins :

  • Un convoyeur adapté pour le transport à plat de ladite fenêtre selon un axe longitudinal, et
  • Au moins un ensemble de fragmentation qui surmonte le convoyeur et est adapté pour fragmenter le verre de ladite fenêtre au cours de son transport sur ledit convoyeur, ledit dispositif étant caractérisé en ce que l'ensemble de fragmentation comprend un tambour agencé au-dessus dudit convoyeur selon un axe de révolution transversal audit axe longitudinal, ledit tambour étant lié par au moins une chaîne à au moins un ensemble percuteur comprenant au moins une tête de percussion adaptée pour percuter le convoyeur à chaque révolution dudit tambour.
The invention aims to respond to the drawbacks described above. More particularly, in at least one embodiment, the proposed technique relates to a fragmentation device suitable for fragmenting the glass of a used window, and comprising at least:
  • A conveyor adapted for the flat transport of said window along a longitudinal axis, and
  • At least one fragmentation assembly which overcomes the conveyor and is adapted to fragment the glass of said window during its transport on said conveyor, said device being characterized in that the fragmentation assembly comprises a drum arranged above said conveyor along an axis of revolution transverse to said longitudinal axis, said drum being linked by at least one chain to at least one striker assembly comprising at least one percussion head adapted to strike the conveyor at each revolution of said drum.

Dans l'ensemble de la description, un dispositif de fragmentation selon l'invention est adapté pour fragmenter le verre d'une fenêtre usagée en ce qu'il permet de séparer le verre et le cadre de cette fenêtre, en vue de son recyclage. La fragmentation du verre désigne l'action de casse, mise en morceaux, concassage, bris du verre d'une fenêtre, afin de le séparer de son cadre et ainsi de pouvoir le recycler. Un convoyeur est un dispositif mécanique adapté pour le transport d'une fenêtre usagée d'un bout à l'autre du dispositif. Un tel convoyeur peut préférentiellement être à bande ou à couloir. Une chaîne est une suite d'anneaux de métal engagés les uns dans les autres. Un tambour désigne un cylindre de bois ou de fer sur lequel vient s'enrouler cette chaîne. Ce tambour est adapté pour effectuer des révolutions, c'est-à-dire des mouvements circulaires effectués autour d'un axe de révolution. Enfin, le verbe « lier » doit être interprété dans son sens mécanique, et peut alternativement se référer à une liaison directe ou indirecte.Throughout the description, a fragmentation device according to the invention is suitable for fragmenting the glass of a used window in that it makes it possible to separate the glass and the frame of this window, with a view to its recycling. The fragmentation of glass refers to the action of breaking, breaking into pieces, crushing, breaking the glass of a window, in order to separate it from its frame and thus be able to recycle it. A conveyor is a mechanical device suitable for transporting a used window from one end of the device to the other. Such a conveyor can preferably be belt or corridor. A chain is a series of metal rings engaged in each other. A drum designates a cylinder of wood or iron on which this chain is wound. This drum is suitable for carrying out revolutions, that is to say circular movements carried out around an axis of revolution. Finally, the verb "to link" must be interpreted in its mechanical sense, and can alternatively refer to a direct or indirect link.

Dans la pratique, le tambour d'un ensemble de fragmentation selon l'invention est mis en rotation, préférentiellement par un moteur, autour d'un axe de révolution transversal à l'axe longitudinal du convoyeur ou en d'autres termes, à sa direction d'avancement. A chaque révolution du tambour, au moins une tête de percussion est d'abord amenée en surplomb du convoyeur pour par la suite venir percuter le tapis du convoyeur, sous l'effet de la gravité.
Le caractère flexible de cette chaîne permet de réduire les sollicitations mécaniques exercées aux points d'ancrage de la chaîne avec le tambour d'une part, et avec l'ensemble percuteur d'autre part.In practice, the drum of a fragmentation assembly according to the invention is rotated, preferably by a motor, around an axis of revolution transverse to the longitudinal axis of the conveyor or in other words, to its direction of advance. At each revolution of the drum, at least one percussion head is first brought overhanging the conveyor to then strike the belt of the conveyor, under the effect of gravity.
The flexible nature of this chain makes it possible to reduce the mechanical stresses exerted on the anchor points of the chain with the drum on the one hand, and with the firing pin assembly on the other hand.

De plus, une telle chaîne ne fournit aucune entrave à l'accélération verticale de chaque tête de percussion, au moment de leur chute, ce qui permet de maximiser la force d'impact de cette tête sur le verre, et donc d'obtenir une fragmentation satisfaisante du verre.Moreover, such a chain does not provide any obstacle to the vertical acceleration of each percussion head, at the moment of their fall, which makes it possible to maximize the force of impact of this head on the glass, and therefore to obtain a satisfactory fragmentation of the glass.

A noter de plus que l'armement de l'ensemble percuteur est plus aisé compte tenu de la répartition avantageuse du poids de cet ensemble percuteur et de la chaîne sur toute leur surface de contact avec le tambour.It should also be noted that cocking the striker assembly is easier given the advantageous distribution of the weight of this striker assembly and of the chain over their entire contact surface with the drum.

Selon un mode de réalisation particulier, ledit ensemble percuteur est lié audit tambour par une pluralité de points d'ancrage, préférentiellement alignés selon un axe transversal.According to a particular embodiment, said striker assembly is linked to said drum by a plurality of anchor points, preferably aligned along a transverse axis.

La multiplication des points d'ancrage permet de répartir le poids de l'ensemble percuteur et de la chaîne entre chacun des points d'ancrage, et ainsi de réduire leur sollicitation respective.The multiplication of the anchor points makes it possible to distribute the weight of the striker assembly and of the chain between each of the anchor points, and thus to reduce their respective stress.

Selon un mode de réalisation particulier, ledit ensemble percuteur est lié audit tambour par une pluralité de chaînes, préférentiellement parallèles entre elles.According to a particular embodiment, said striker assembly is linked to said drum by a plurality of chains, preferably parallel to each other.

La multiplication du nombre de chaînes permet de répartir le poids de l'ensemble percuteur entre elles, et ainsi de réduire leur sollicitation respective. La mise en oeuvre d'une pluralité de chaînes permet de plus de faciliter l'équilibrage de l'ensemble percuteur, en particulier lors de l'étape de fragmentation.The multiplication of the number of chains makes it possible to distribute the weight of the striker assembly between them, and thus to reduce their respective stress. The implementation of a plurality of chains further makes it easier to balance the striker assembly, in particular during the fragmentation step.

Selon un mode de réalisation particulier, ledit ensemble percuteur comprend une pluralité de têtes de percussion alignées selon une direction transversale.According to a particular embodiment, said striker assembly comprises a plurality of percussion heads aligned in a transverse direction.

La collision simultanée d'une pluralité de têtes avec le verre permet de maximiser la puissance instantanée de l'impact tout en la répartissant sur une grande surface de verre. Il est ainsi possible de fragmenter efficacement la fenêtre usagée ciblée, en une multitude de bris de verre.The simultaneous collision of a plurality of heads with the glass makes it possible to maximize the instantaneous power of the impact while distributing it over a large surface of glass. It is thus possible to effectively fragment the targeted used window into a multitude of broken glass.

Selon un mode de réalisation particulier, ledit ensemble percuteur comprend au moins une barre transversale de lestage.According to a particular embodiment, said striker assembly comprises at least one transverse ballast bar.

La mise en oeuvre d'une telle barre transversale de lestage permet d'accroître la force d'impact de l'ensemble percuteur.The implementation of such a transverse ballast bar makes it possible to increase the impact force of the striker assembly.

Selon un mode de réalisation particulier, ladite barre transversale lie une pluralité de têtes de percussion entre elles.According to a particular embodiment, said crossbar binds a plurality of percussion heads together.

Dans une telle configuration, une telle barre permet de faciliter l'alignement transversal des têtes, et donc leur synchronisation au moment de l'impact.In such a configuration, such a bar makes it possible to facilitate the transverse alignment of the heads, and therefore their synchronization at the moment of impact.

Selon un mode de réalisation particulier, chaque tête de percussion est liée au tambour par une chaîne respective.According to a particular embodiment, each percussion head is linked to the drum by a respective chain.

Selon un mode de réalisation particulier, au moins une tête de percussion est liée audit tambour par l'intermédiaire de ladite barre transversale.According to a particular embodiment, at least one percussion head is linked to said drum via said transverse bar.

Il est ainsi possible d'agencer un nombre variable de têtes de percussion sur la barre transversale, indépendamment du nombre de chaînes mis en oeuvre et de la localisation de leur point de fixation sur la barre.It is thus possible to arrange a variable number of percussion heads on the crossbar, independently of the number of chains used and of the location of their attachment point on the bar.

Selon un mode de réalisation particulier, au moins une tête est liée à ladite barre transversale par l'intermédiaire d'une chaîne.According to a particular embodiment, at least one head is linked to said transverse bar by means of a chain.

Selon un mode de réalisation particulier, ledit ensemble percuteur est lié audit tambour par M chaînes, préférentiellement parallèles entre elles, en ce que ledit ensemble percuteur comprend N têtes de percussion, et en ce que N est strictement supérieur à M.According to a particular embodiment, said striker assembly is linked to said drum by M chains, preferably parallel to each other, in that said striker assembly comprises N percussion heads, and in that N is strictly greater than M.

Il est ainsi possible d'accroître le nombre de points d'impact avec le verre, indépendamment du nombre de chaînes mis en oeuvre.It is thus possible to increase the number of points of impact with the glass, independently of the number of chains implemented.

Selon un mode de réalisation particulier, l'ensemble formé par ladite chaîne et l'ensemble percuteur présente une longueur inférieure ou égale à la distance, inscrite selon un axe théorique vertical tangent à l'arrière du tambour, qui sépare l'arrière du tambour du convoyeur.According to a particular embodiment, the assembly formed by said chain and the striker assembly has a length less than or equal to the distance, inscribed along a theoretical vertical axis tangent to the rear of the drum, which separates the rear of the drum of the conveyor.

Dans tout le texte, l'avant et l'arrière du dispositif sont définis le long de l'axe longitudinal du convoyeur, le tapis du convoyeur étant adapté pour transporter une fenêtre usagée depuis l'arrière vers l'avant du dispositif. La mise en oeuvre d'une chaîne d'une longueur inférieure ou égale à cette distance D permet d'éviter que la chaîne ne reste trop longtemps sur le tapis convoyeur, afin notamment de limiter l'abrasion des têtes de fragmentation par le verre pilé présent sur le tapis du convoyeur.Throughout the text, the front and rear of the device are defined along the longitudinal axis of the conveyor, the conveyor belt being adapted to transport a used window from the rear to the front of the device. The implementation of a chain with a length less than or equal to this distance D makes it possible to prevent the chain from remains too long on the conveyor belt, in particular to limit abrasion of the fragmentation heads by the crushed glass present on the conveyor belt.

Selon un mode de réalisation particulier, le dispositif de fragmentation comprend une pluralité d'ensembles percuteurs liés respectivement au tambour par au moins une chaîne.According to a particular embodiment, the fragmentation device comprises a plurality of striker assemblies linked respectively to the drum by at least one chain.

Il est ainsi possible de fragmenter une pluralité de fois le verre d'une fenêtre usagée, à chaque nouvelle révolution du tambour.It is thus possible to fragment a plurality of times the glass of a used window, with each new revolution of the drum.

Selon un mode de réalisation particulier, ledit convoyeur comprend un tapis, préférentiellement nervuré, ledit tambour et les moyens d'entraînement dudit tapis étant adaptés pour être mis en rotation selon des directions opposées.According to a particular embodiment, said conveyor comprises a belt, preferably ribbed, said drum and the drive means of said belt being adapted to be rotated in opposite directions.

Une telle opposition de sens de rotation entre le tambour et le tapis de convoyage permet de limiter les risques de voir l'ensemble de fragmentation, et en particulier sa (ses) tête(s) de percussion, entraîner le cadre d'une fenêtre usagée vers l'arrière.Such an opposition of direction of rotation between the drum and the conveyor belt makes it possible to limit the risks of seeing the fragmentation assembly, and in particular its percussion head(s), dragging the frame of a used window. rearward.

La mise en oeuvre de nervures à la surface du tapis de convoyage permet de limiter les zones de contact entre ce dernier et la fenêtre usagée, en concentrant au niveau de ces seules zones les forces de réaction du tapis générées au moment de l'impact.The implementation of ribs on the surface of the conveyor belt makes it possible to limit the zones of contact between the latter and the used window, by concentrating at the level of these zones alone the reaction forces of the belt generated at the moment of impact.

L'invention concerne aussi un procédé de fragmentation du verre d'une fenêtre, caractérisé en ce qu'il met en oeuvre un dispositif de fragmentation adapté pour fragmenter le verre d'une fenêtre usagée, et comprenant au moins :

  • Un convoyeur adapté pour le transport à plat de ladite fenêtre selon un axe longitudinal, et
  • Un ensemble de fragmentation qui surmonte le convoyeur et est adapté pour fragmenter le verre de ladite fenêtre au cours de son transport sur ledit convoyeur, l'ensemble de fragmentation comprenant un tambour agencé au-dessus dudit convoyeur selon un axe de révolution transversal audit axe longitudinal, ledit tambour étant lié par au moins une chaîne à un ensemble percuteur comprenant au moins une tête de percussion adaptée pour percuter ledit convoyeur à chaque révolution dudit tambour.
The invention also relates to a process for fragmenting the glass of a window, characterized in that it uses a fragmentation device suitable for fragmenting the glass of a used window, and comprising at least:
  • A conveyor adapted for the flat transport of said window along a longitudinal axis, and
  • A fragmentation assembly which surmounts the conveyor and is adapted to fragment the glass of said window during its transport on said conveyor, the fragmentation assembly comprising a drum arranged above said conveyor according to an axis of revolution transverse to said longitudinal axis , said drum being linked by at least one chain to a striker assembly comprising at least one striker head adapted to strike said conveyor at each revolution of said drum.

Selon un mode de réalisation particulier, ledit tambour et les moyens d'entraînement dudit convoyeur sont mis en rotation selon des directions opposées.According to a particular embodiment, said drum and the drive means of said conveyor are rotated in opposite directions.

Selon un mode de réalisation particulier, le rapport entre la vitesse d'avancement du tapis convoyeur et la vitesse de révolution du tambour est choisi de sorte que ladite fenêtre est, au cours de son transport à plat sur ledit convoyeur, percutée par ledit ensemble de fragmentation au moins deux fois, préférentiellement au moins trois fois, préférentiellement au moins quatre fois, préférentiellement au moins cinq fois.According to a particular embodiment, the ratio between the forward speed of the conveyor belt and the speed of revolution of the drum is chosen so that said window is, during its flat transport on said conveyor, struck by said fragmentation assembly at least twice, preferably at least three times, preferably at least four times, preferably at least five times.

L'augmentation de la fréquence de percussion permet de réduire la taille des bris de verre, et donc de faciliter leur tri et/ou leur recyclage ultérieur.The increase in the frequency of percussion makes it possible to reduce the size of broken glass, and therefore to facilitate their sorting and/or their later recycling.

Selon un mode de réalisation particulier, le procédé de fragmentation comprend une étape ultérieure de collecte distincte du verre fragmenté d'une part, et du cadre de ladite fenêtre d'autre part.According to a particular embodiment, the fragmentation method comprises a subsequent step of separate collection of the fragmented glass on the one hand, and of the frame of said window on the other hand.

Le verre et le cadre étant de composition différente, leur collecte distincte, par exemple dans des réceptacles ou bacs distincts, permet d'en faciliter le recyclage.The glass and the frame being of different composition, their separate collection, for example in separate receptacles or bins, facilitates recycling.

Tel qu'illustré par la Figure 2, un dispositif de fragmentation 1 selon un mode de réalisation particulier de l'invention est adapté pour fragmenter le verre d'une fenêtre 2 usagée, et comprend :

  • Un convoyeur 3 adapté pour le transport à plat de la fenêtre 2 selon un axe longitudinal L, et
  • Un ensemble de fragmentation 4 qui surmonte le convoyeur 3 et est adapté pour fragmenter le verre de la fenêtre 2 au cours de son transport sur le convoyeur 3.
As illustrated by the Figure 2 , a fragmentation device 1 according to a particular embodiment of the invention is suitable for fragmenting the glass of a used window 2, and comprises:
  • A conveyor 3 adapted for the flat transport of the window 2 along a longitudinal axis L, and
  • A fragmentation assembly 4 which overcomes the conveyor 3 and is adapted to fragment the glass of the window 2 during its transport on the conveyor 3.

Plus précisément, l'ensemble de fragmentation 4 comprend un tambour 5 agencé au-dessus du convoyeur 3 selon un axe de révolution R transversal à l'axe longitudinal L.More specifically, the fragmentation assembly 4 comprises a drum 5 arranged above the conveyor 3 along an axis of revolution R transverse to the longitudinal axis L.

Le tambour 5 est lié à deux ensembles percuteurs (71, 72) par deux groupements de chaînes 6ay, chaque ensemble percuteur 71 comprenant une pluralité de têtes (7a1, 7a2,...,7az) de percussion adaptées pour percuter le convoyeur 3 à chaque révolution du tambour 5.The drum 5 is linked to two striker assemblies (7 1 , 7 2 ) by two groups of chains 6ay, each striker assembly 7 1 comprising a plurality of percussion heads (7a1, 7a2,..., 7az) suitable for striking the conveyor 3 with each revolution of the drum 5.

Pour chaque ensemble percuteur 7, les têtes de percussions (7a1, 7a2, ..., 7az) sont alignées selon une direction transversale Rz. Aussi, à des fins de clarté et compte tenu du fait que la Figure 2 est une vue schématique en coupe effectuée selon un plan perpendiculaire à cette direction transversale, seule une chaîne 6ay et une tête de percussion 7az sont représentées par ensemble percuteur 7.For each striker assembly 7, the percussion heads (7a1, 7a2, ..., 7az) are aligned in a transverse direction Rz. Also, for the sake of clarity and taking into account that the Figure 2 is a schematic sectional view taken along a plane perpendicular to this transverse direction, only a chain 6ay and a percussion head 7az are shown per striker assembly 7.

Selon des modes de réalisations alternatifs, l'ensemble de fragmentation 4 peut ne comprendre qu'un ou au contraire plus de deux ensembles percuteurs 7, chaque ensemble percuteur 7 pouvant comprendre une ou plusieurs têtes de percussion 7az.According to alternative embodiments, the fragmentation assembly 4 may comprise only one or on the contrary more than two striker assemblies 7, each striker assembly 7 possibly comprising one or more percussion heads 7az.

Dans la pratique, une fenêtre usagée 2 est d'abord chargée sur tapis de convoyage 3a, à l'arrière du dispositif 1. Cette fenêtre usagée 2 est ensuite acheminée par le convoyeur 3 au niveau de l'ensemble de fragmentation 4, c'est-à-dire approximativement en contrebas du tambour 5. Ce tambour 5 est mis en rotation, préférentiellement par un moteur, autour d'un axe de révolution R transversal à l'axe longitudinal L du convoyeur 3 ou en d'autres termes, à sa direction d'avancement. Cette direction d'avancement est représentée sur la Figure 2 par une flèche directionnelle en pointillés.In practice, a used window 2 is first loaded onto a conveyor belt 3a, at the rear of the device 1. This used window 2 is then transported by the conveyor 3 to the level of the fragmentation assembly 4, it that is to say approximately below the drum 5. This drum 5 is rotated, preferably by a motor, around an axis of revolution R transverse to the longitudinal axis L of the conveyor 3 or in other words, to its direction of advancement. This direction of travel is shown on the Figure 2 by a dotted directional arrow.

Selon le mode de réalisation particulier illustré par la Figure 2, le tambour 5 et les moyens d'entraînement du convoyeur 3 sont mis en rotation selon des directions opposées, chacune de ces directions étant représentées par des flèches directionnelles en pointillés. Ainsi, à chaque révolution du tambour 5, au moins une tête de percussion 7az est d'abord amenée en surplomb du convoyeur 3 pour par la suite venir percuter le tapis du convoyeur 3a, sous l'effet de son poids. Lors de la fragmentation, le verre 2a de la fenêtre usagée 2 est ainsi séparé de son cadre 2b, en vue d'un futur tri/recyclage.According to the particular embodiment illustrated by the Figure 2 , the drum 5 and the drive means of the conveyor 3 are rotated in opposite directions, each of these directions being represented by dotted directional arrows. Thus, at each revolution of the drum 5, at least one percussion head 7az is first brought overhanging the conveyor 3 to subsequently strike the belt of the conveyor 3a, under the effect of its weight. During fragmentation, the glass 2a of the used window 2 is thus separated from its frame 2b, with a view to future sorting/recycling.

Tel qu'illustré par la Figure 2, l'ensemble formé par la chaîne 6ay et l'ensemble percuteur 71 présente une longueur égale à la distance D, inscrite selon un axe théorique vertical tangent à l'arrière du tambour 5, qui sépare l'arrière du tambour 5 du convoyeur 3. Cela permet d'éviter que la chaîne 6ay ne reste trop longtemps sur le tapis 3a convoyeur, afin notamment de limiter l'abrasion des têtes de fragmentation 7az par le verre pilé présent sur le tapis du convoyeur.As illustrated by the Figure 2 , the assembly formed by the chain 6ay and the striker assembly 7 1 has a length equal to the distance D, inscribed along a theoretical vertical axis tangent to the rear of the drum 5, which separates the rear of the drum 5 from the conveyor 3. This makes it possible to prevent the chain 6ay from remaining too long on the conveyor belt 3a, in order in particular to limit the abrasion of the fragmentation heads 7az by the crushed glass present on the conveyor belt.

Le caractère flexible de cette chaîne 6ay permet de réduire les sollicitations mécaniques exercées aux points d'ancrage 5ax de la chaîne 6ay avec le tambour 5 d'une part, et avec l'ensemble percuteur 7 d'autre part. De plus, une telle chaîne 6ay ne fournit aucune entrave à l'accélération verticale de chaque tête de percussion 7az, au moment de leur chute, ce qui permet de maximiser la force d'impact de cette tête sur le verre 8b de la fenêtre usagée 2, et donc d'obtenir une fragmentation satisfaisante de ce verre 8b.The flexible character of this chain 6ay makes it possible to reduce the mechanical stresses exerted on the anchor points 5ax of the chain 6ay with the drum 5 on the one hand, and with the striker assembly 7 on the other hand. Moreover, such a chain 6ay does not provide any obstacle to the vertical acceleration of each percussion head 7az, at the moment of their fall, which makes it possible to maximize the force of impact of this head on the glass 8b of the used window. 2, and therefore to obtain a satisfactory fragmentation of this glass 8b.

A noter de plus que l'armement de l'ensemble percuteur 7 est plus aisé compte tenu de la répartition avantageuse du poids de cet ensemble percuteur 7 et de la chaîne 6ay sur toute leur surface de contact avec le tambour 5.It should also be noted that the cocking of the striker assembly 7 is easier given the advantageous distribution of the weight of this striker assembly 7 and of the chain 6ay over their entire contact surface with the drum 5.

Selon un mode de réalisation particulier, le rapport entre la vitesse d'avancement du tapis convoyeur 3 et la vitesse de révolution du tambour 5 est choisi de sorte que la fenêtre 2 est, au cours de son transport à plat sur ledit convoyeur 3, percutée par un ensemble de fragmentation 4 au moins cinq fois.According to a particular embodiment, the ratio between the forward speed of the conveyor belt 3 and the speed of revolution of the drum 5 is chosen so that the window 2 is, during its transport flat on said conveyor 3, struck by a set of fragmentation 4 at least five times.

Les figure 3 et 4 sont des vues en perspective prises depuis l'arrière de l'ensemble de fragmentation 4 qui surmonte le convoyeur 3 d'un dispositif de fragmentation 1 selon un mode de réalisation particulier de l'invention.THE figures 3 and 4 are perspective views taken from the rear of the fragmentation assembly 4 which overcomes the conveyor 3 of a fragmentation device 1 according to a particular embodiment of the invention.

Cet ensemble de fragmentation 4 comprend trois ensembles percuteurs (71, 72, 73). Chaque ensemble percuteur (71, 72, 73) comprend une pluralité de têtes de percussion (7a1, 7a2,..., 7az) qui sont liées au tambour 5 via une pluralité de points d'ancrage (5a1, 5a2,..., 5ax). Les têtes de percussion (7a1, 7a2,..., 7az) et points d'ancrage (5a1, 5a2,..., 5ax) sont alignées selon des axes transversaux respectifs (Rz, Rx).This fragmentation set 4 comprises three striker sets (7 1 , 7 2 , 7 3 ). Each striker assembly (7 1 , 7 2 , 7 3 ) comprises a plurality of percussion heads (7a1, 7a2,..., 7az) which are linked to the drum 5 via a plurality of anchor points (5a1, 5a2, ..., 5ax). The percussion heads (7a1, 7a2,..., 7az) and anchor points (5a1, 5a2,..., 5ax) are aligned along respective transverse axes (Rz, Rx).

Selon ce même mode de réalisation, les têtes de percussion (7a1, 7a2,..., 7az) et les chaînes (6a1, 6a2,..., 6ay) sont liées entre elles par une barre transversale 8 de lestage. A noter que chacun des ensembles percuteurs (71, 72, 73) représentés sur les Figure 3 et 4 est lié au tambour 5 par quatre chaînes (6a1, 6a2, ..., 6ay), et comprend sept têtes de percussion (7a1, 7a2,..., 7az), une tête sur deux étant ainsi liée au tambour 5 par l'intermédiaire de la barre transversale 8. Le nombre de points d'impact avec le verre est donc considérablement accru, indépendamment du nombre de chaînes mis en oeuvre.According to this same embodiment, the percussion heads (7a1, 7a2, ..., 7az) and the chains (6a1, 6a2, ..., 6ay) are linked together by a transverse bar 8 of ballast. Note that each of the striker assemblies (7 1 , 7 2 , 7 3 ) represented on the Figure 3 and 4 is linked to the drum 5 by four chains (6a1, 6a2, ..., 6ay), and comprises seven percussion heads (7a1, 7a2, ..., 7az), one out of two heads being thus linked to the drum 5 by through the crossbar 8. The number of points of impact with the glass is therefore considerably increased, independently of the number of chains used.
