Description

L'invention est relative à un appareil à sectionner la bande de roulement d'un pneumatique sans ses flancs.The invention relates to an apparatus for severing the tread of a tire without its sidewalls.

Les pneumatiques, usagés et devenus inutilisables, représentent un volume considérable de matériau non biodégradable qu'il faut stocker en attente de destruction future, par fragmentation ou combustion.Tires, used and unusable, represent a considerable volume of non-biodegradable material that must be stored pending future destruction, fragmentation or combustion.

Les pneumatiques sont composés de gomme renforcée par une armature interne de fils, métalliques ou synthétiques, maintenant leur forme torique, quand ils ne sont pas montés sur une jante. En raison de cette structure torique ils occupent un volume important, mais, surtout, forment un ensemble ne pouvant être manipulé qu'à la main aussi bien pour leur stockage que pour leur traitement de destruction.The tires consist of rubber reinforced by an internal reinforcement of wire, metallic or synthetic, maintaining their toric shape, when they are not mounted on a rim. Because of this toric structure they occupy a large volume, but above all, form an assembly that can be handled only by hand for both storage and destruction treatment.

Il résulte de cela que les appareils de destruction connus ont une cadence de fonctionnement réduite et ne permettent pas de résorber l'important stock de pneumatiques usagés qui s'accumule de partout et défigure le paysage des zones rurales.As a result, the known destruction devices have a reduced operating speed and do not allow to reduce the large stock of used tires that accumulates everywhere and disfigures the landscape of rural areas.

Actuellement, la destruction par fragmentation de chaque pneumatique s'effectue, hors déchiquetage, avec des appareils qui soit sectionnent l'enveloppe en la découpant suivant son plan médian, comme dans les documents DE2544002 et DE2344479 , soit, comme dans les documents, GB379302 , DE4200949 , WO9824607 et FR2780675 , séparent par sectionnement les flancs de la bande de roulement.Currently, fragmentation destruction of each tire takes place, excluding shredding, with devices that cut the envelope by cutting it along its median plane, as in documents DE2544002 and DE2344479 either, as in the documents, GB379302 , DE4200949 , WO9824607 and FR2780675 , separating by cutting the sides of the tread.

L'invention concerne plus spécialement les bandes de roulement séparées de leurs flancs et formant un anneau.The invention relates more particularly to the treads separated from their sides and forming a ring.

Pour pouvoir l'utiliser et le développer à plat, cet anneau est en général découpé transversalement au moyen d'une guillotine, d'un massicot ou d'une cisaille. Il s'agit là d'une opération manuelle qui ralentit la cadence et consomme des outils tranchants qu'il faut affuter régulièrement.In order to use it and develop it flat, this ring is generally cut transversely by means of a guillotine, a cutter or a shear. This is a manual operation that slows down the pace and consumes sharp tools that must be sharpened regularly.

La présente invention à pour but de fournir un appareil simple permettant de découper la bande de roulement en anneau de manière rapide, sans manipulation fastidieuse, et avec un entretien réduit.The present invention aims to provide a simple device for cutting the ring tread quickly, without tedious handling, and with reduced maintenance.

A cette fin, l'appareil selon l'invention comprend, d'une part, une lame transversale amovible ayant une longueur au moins égale à la largeur de la bande de roulement et reliée à des moyens aptes la déplacer longitudinalement dans les deux sens, avec une force suffisante pour rompre la dite bande par striction et, d'autre part, au moins un moyen d'appui pour la bande de roulement, quand celle-ci est disposée sur l'appareil en entourant cet appui et la lame.To this end, the apparatus according to the invention comprises, on the one hand, a removable transverse blade having a length at least equal to the width of the tread and connected to means able to move it longitudinally in both directions, with sufficient force to break said strip by necking and, secondly, at least one support means for the tread, when it is disposed on the apparatus by surrounding the support and the blade.

Le déplacement de la lame en direction de l'extérieur de l'anneau formé par la bande de roulement, amène celle-ci en appui contre la lame et contre son autre appui, étire l'anneau en rapprochant ses brins, puis, l'allongement se poursuivant, provoque la rupture par allongement de la bande dans sa zone d'appui contre la lame. Cette rupture s'effectue de façon mécanique, sans intervention d'aucun autre moyen de coupe, donc sans qu'il faille de temps à autre aiguiser un tranchant émoussé.The movement of the blade towards the outside of the ring formed by the tread, brings it to bear against the blade and against its other support, stretches the ring by bringing its strands closer, then, the elongation continues, causes the rupture by elongation of the band in its bearing zone against the blade. This break is done mechanically, without the intervention of any other cutting means, so without it need from time to time sharpen a blunt cutting edge.

De préférence, la lame transversale est portée par la tige d'un vérin hydraulique dont le corps fixe est lié au châssis de l'appareil.Preferably, the transverse blade is carried by the rod of a hydraulic cylinder whose fixed body is connected to the frame of the apparatus.

Cette réalisation permet de disposer de la force nécessaire pour parvenir à la striction de la bande de roulement, sans utilisation de moyens tranchants pénétrant dans la gomme et s'émoussant.This embodiment provides the necessary force to achieve the necking of the tread, without the use of cutting means penetrating into the rubber and blunting.

On notera que cette striction s'effectue d'autant mieux que la bande de roulement est séparée de ses flancs qui, par leur armature interne, tendent normalement à lui donner une forme circulaire.It will be noted that this necking is all the better that the tread is separated from its flanks which, by their internal armature, tend normally to give it a circular shape.

Dans une forme d'exécution, le moyen d'appui est constitué par un talon transversal solidaire du corps de vérin et disposé à son extrémité opposée à celle de laquelle sort la tige portant la lame.In one embodiment, the support means is constituted by a transverse heel integral with the cylinder body and disposed at its end opposite to that of which the rod carrying the blade.

Ainsi, la mise en place de la bande de roulement à sectionner sur l'appareil s'effectue rapidement et en une seule fois par engagement de cette bande autour de la lame et du talon. Cette opération est instinctive et immédiate.Thus, the introduction of the tread to be cut on the device is performed quickly and all at once by engagement of this band around the blade and heel. This operation is instinctive and immediate.

Dans une autre forme d'exécution, le moyen d'appui est constitué par au moins deux pinces disposées de part et d'autre de la lame et comprenant, chacune, une mâchoire fixe, disposée à l'intérieur de la zone annulaire de mise en place de la bande, et une mâchoire écartable disposée à l'extérieur de cette zone.In another embodiment, the support means is constituted by at least two clamps disposed on either side of the blade and each comprising a fixed jaw disposed inside the annular zone in place of the band, and a jaw spreadable disposed outside this area.

Cette réalisation augmente l'intérêt de l'appareil, puisqu'il permet de sectionner la bande en plusieurs tronçons, de sectionner des tronçons déjà découpés dans une bande et d'adapter aux besoins la longueur des tronçons.This embodiment increases the interest of the apparatus, since it allows to cut the strip into several sections, to cut sections already cut in a strip and to adapt the length of the sections to the needs.

D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé représentant plusieurs formes d'exécution de l'appareil.

  • Figures 1 et 2 sont des vues de coté en élévation d'une forme d'exécution de l'appareil, au repos ;
  • Figures 3 et 4 sont des vues similaires mais quand l'appareil est en fin d'extension, avant rupture par striction de la bande ;

  • Figure 7 est une vue de coté en élévation du même appareil pendant l'opération de sectionnement du tronçon supérieur.
Other features and advantages will become apparent from the description which follows with reference to the attached schematic drawing showing several embodiments of the apparatus.
  • Figures 1 and 2 are side views in elevation of one embodiment of the apparatus, at rest;
  • Figures 3 and 4 are similar views but when the apparatus is at the end of extension, before rupture by necking of the band;
  • Figures 5 and 6 are views in elevation, respectively of side and in plan on top, of another form of execution of the apparatus;
  • Figure 7 is a side view in elevation of the same apparatus during the sectioning operation of the upper section.

De manière générale, le châssis 2 de l'appareil comprend un socle 3 avec une console 4 portant verticalement le corps 5 d'un vérin hydraulique vertical 5-6 dont la tige 6 s'étend vers le haut. Les moyens d'alimentation en fluide hydraulique, de même que les moyens de commande de ce vérin ne sont pas représentés, car ils sont bien connus de l'homme de métier.In general, the frame 2 of the apparatus comprises a base 3 with a bracket 4 vertically supporting the body 5 of a vertical hydraulic cylinder 5-6 whose rod 6 extends upwards. The hydraulic fluid supply means, as well as the control means of this jack are not shown because they are well known to those skilled in the art.

L'extrémité libre de la tige 6 du vérin est liée, par exemple par un boulon 7, à une lame 8, transversale, interchangeable et dont la longueur L est au moins égale et de préférence supérieure à la largeur E de la bande de roulement 10. En pratique la lame a une largeur de l'ordre de 300 millimètresThe free end of the rod 6 of the jack is connected, for example by a bolt 7, to a transverse blade 8, interchangeable and whose length L is at least equal and preferably greater than the width E of the tread 10. In practice the blade has a width of the order of 300 millimeters

La lame 8 constitue l'un des points d'appui sur lesquels la bande 10 est mise en place manuellement. L'autre point d'appui est constitué par un talon 9 formé à l'extrémité du corps de vérin 5 par le bras de la console 4, comme le montre la figure 2.The blade 8 is one of the points of support on which the strip 10 is set up manually. The other point of support is constituted by a heel 9 formed at the end of the cylinder body 5 by the arm of the console 4, as shown in FIG. figure 2 .

L'appareil étant au repos avec son vérin 5-6 rétracté, comme montré à la figure 3, l'opérateur place sur lui l'anneau formé par la bande de roulement 10, en prenant soin que la lame 8 et le talon 9 soit à l'intérieur de cet anneau de forme générale ovale.The apparatus being at rest with its retracted cylinder 5-6, as shown in FIG. figure 3 , the operator places on it the ring formed by the tread 10, taking care that the blade 8 and the heel 9 is inside this generally oval ring.

A ce stade, l'opérateur commande l'alimentation du vérin hydraulique 5-6, dans le sens de l'extension de sa tige 6.At this stage, the operator controls the supply of the hydraulic cylinder 5-6, in the direction of extension of its rod 6.

Comme le montre la figure 4, sous cet effort dans le sens de la flèche 11 la bande 10 s'étire localement et prend une forme longiligne, jusqu'à ce que, sous la poussée de la lame 8, elle soit soumise en S à une striction amenant sa rupture.As shown in figure 4 , under this force in the direction of the arrow 11 the strip 10 stretches locally and takes an elongated shape, until, under the thrust of the blade 8, it is subjected in S to a necking causing its rupture.

Bien entendu, à la fin du cycle, la tige 6 est rétractée et revient à sa position d'origine, pour accueillir un nouvel anneau de bande 10.Of course, at the end of the cycle, the rod 6 is retracted and returns to its original position, to accommodate a new band ring 10.

En pratique l'ensemble de l'opération est très rapide, puisque le temps nécessaire à la mise en place de la bande sur l'appareil et le retrait de la bande découpée est de l'ordre de 20 secondes. Cela permet d'intégrer l'appareil à une opération séparant la bande de roulement de ses flancs, afin d'augmenter la rentabilité des opérations.In practice the whole operation is very fast, since the time required to set up the strip on the device and the removal of the cut strip is of the order of 20 seconds. This makes it possible to integrate the device into an operation separating the tread from its flanks, in order to increase the profitability of the operations.

Il faut remarquer que cet appareil n'utilise aucun consommable et que le mode de sectionnement n'impose pas de remplacer la lame régulièrement. Par ailleurs, si la lame présente une arête centrale biseautée, elle n'a pas besoin d'être aiguisée, car elle ne tranche pas la gomme mais lui communique l'effort tranchant qui provoque sa striction.It should be noted that this unit does not use any consumables and that the sectioning mode does not require replacing the blade regularly. Furthermore, if the blade has a beveled central edge, it does not need to be sharp, because it does not slice the gum but communicates the shear force that causes its necking.

Les figures 1 à 4 montrent que le bras 4 de console est en surélévation par rapport au sol d'une valeur D afin que la zone annulaire de mise en place de la bande soit éloignée du sol et que la mise en place de l'anneau de bande s'effectue aisément.The Figures 1 to 4 show that the console arm 4 is elevated with respect to the ground by a value D so that the annular zone of installation of the band is removed from the ground and that the establishment of the band ring is effected easily.

Les moyens qui sont décrits ci-dessus comme étant verticaux, peuvent aussi être horizontaux ou inclinés, si le châssis porte, comme représenté en traits mixtes 12 à la figure 3, un plateau fixe 12 empêchant la bande de s'échapper, tant qu'elle n'est pas soumise à l'effort d'étirement par la lame 8 et le talon 9.The means which are described above as being vertical, can also be horizontal or inclined, if the frame carries, as shown in phantom 12 at the figure 3 , a fixed plate 12 preventing the band from escaping, as long as it is not subjected to the stretching force by the blade 8 and the heel 9.

La forme de réalisation des figures 5 à 7 est relative à une variante dans laquelle l'appareil comporte des moyens complémentaires d'appui et de pincement de la bande 10. Ces moyens sont constitués par des pinces P1 et P2 disposées de part et d'autre de la lame 8 et comprenant chacune :

  • une mâchoire fixe 20 en forme de plateau, portée par un bras 21 fixés sur le corps 5 du vérin,
  • une mâchoire écartable 22 formée par un plateau calé à l'extrémité de la tige 23 d'un vérin hydraulique, dont le corps 24 est porté par une potence 25 du châssis 2.
The embodiment of the Figures 5 to 7 relates to a variant in which the apparatus comprises complementary means of support and pinching of the strip 10. These means consist of clamps P1 and P2 disposed on either side of the blade 8 and each comprising:
  • a fixed jaw 20 in the form of a plate, carried by an arm 21 fixed on the body 5 of the jack,
  • a spreadable jaw 22 formed by a plate wedged at the end of the rod 23 of a hydraulic cylinder, whose body 24 is carried by a bracket 25 of the frame 2.

Les figures 5 et 7 montrent que les mâchoires 20 sont disposées à l'intérieur de la zone annulaire de mise en place de la bande de roulement 10 tandis que celles déplaçables 22 sont disposées à l'extérieur de cette zone.The Figures 5 and 7 show that the jaws 20 are disposed within the annular zone of implementation of the tread 10 while the displaceable 22 are disposed outside this zone.

Dans cette application, avant de commander l'extension de la tige 6 du vérin 5-6, l'opérateur commande le pincement des mâchoires 20-22 afin d'immobiliser le tronçon supérieur T allant d'une paire de mâchoires à l'autre en passant par la lame 8. L'extension de la tige 6 provoque, par appui de la lame 8, le sectionnement par striction du tronçon T.In this application, before controlling the extension of the rod 6 of the jack 5-6, the operator controls the clamping of the jaws 20-22 in order to immobilize the upper section T going from one pair of jaws to the other through the blade 8. The extension of the rod 6 causes, by pressing the blade 8, the sectioning by necking of the section T.

Aux figures 5 et 7, le châssis 2 porte aussi le talon 9, car l'appareil peut être utilisé indifféremment pour sectionner des tronçons de bandes prédécoupées ou des bandes en anneaux, mais en pratique il est utilisé pour sectionner des tronçons non annulaires de bandes de roulement pour adapter leur longueur aux besoins. C'est ainsi qu'une même bande de roulement peut être sectionnée plusieurs fois dans sa longueur.To the Figures 5 and 7 , the frame 2 also carries the heel 9, because the apparatus can be used indifferently to cut sections of pre-cut strips or bands rings, but in practice it is used to cut non-annular sections of treads to adapt their shape. length to needs. Thus, the same tread can be cut several times in its length.

En outre, avec cet appareil, la bande de roulement peut être amenée sur l'appareil, sous sa forme annulaire et sous forme de tronçons discontinus.In addition, with this apparatus, the tread can be brought to the apparatus, in its annular form and in the form of discontinuous sections.

Les bandes obtenues par l'un ou l'autre des appareils peuvent, après mise à plat, être utilisées plus facilement, par exemple pour constituer par agrafage des tapis disposés dans les ballasts de voies pour absorber les vibrations et les bruits de roulement, mais aussi dans toutes autres applications exigeant une alimentation régulière en forme et dimensions, telles que pour l'obtention de semelles par poinçonnage.The strips obtained by one or the other of the devices can, after flattening, be used more easily, for example to constitute by stapling of the mats arranged in the track ballasts to absorb the vibrations and rolling noises, but also in all other applications requiring a regular supply of shape and dimensions, such as for obtaining soles by punching.
