Description

Procédé de transport de pneumatiques en provenance d’un poste de cuisson Method for transporting tires from a curing station
[0001] L'invention concerne le transport des pneumatiques destinés à être montés sur une roue de véhicule et, plus précisément, le transport des ébauches crues de pneumatique ou des pneumatiques cuits, respectivement, à destination ou en provenance d’un poste de cuisson de pneumatiques. [0001] The invention relates to the transport of tires intended to be mounted on a vehicle wheel and, more specifically, the transport of raw tire blanks or cured tires, respectively, to or from a curing station. of tyres.
[0002] Pour fabriquer un pneumatique, on réalise une ébauche de pneumatique comprenant notamment de la gomme crue. On transporte ensuite l’ébauche de gomme crue jusqu'à un poste de cuisson auquel ont lieu son moulage et sa vulcanisation, de manière à obtenir un pneumatique de gomme cuite à la forme et aux caractéristiques mécaniques voulues. [0002] To manufacture a tire, a tire blank is produced comprising in particular raw rubber. The raw rubber blank is then transported to a curing station where it is molded and vulcanized, so as to obtain a cured rubber tire with the desired shape and mechanical characteristics.
[0003] Le document W02013160606A1, au nom des demanderesses, décrit un procédé de transport de pneumatiques dans lequel : [0003] Document WO2013160606A1, in the name of the applicants, describes a method for transporting tires in which:
- un chariot se déplace sur des rails de guidage au sol, le chariot transportant au moins une ébauche crue de pneumatique sur un support adapté, jusqu'à une zone prédéterminée de chargement d'un poste de cuisson ; - A carriage moves on guide rails on the ground, the carriage transporting at least one green tire blank on a suitable support, to a predetermined loading zone of a cooking station;
- au moins un pneumatique cuit est transféré du poste de cuisson au chariot, et la ou chaque ébauche crue de pneumatique est transférée du chariot au poste de cuisson ; - at least one cured tire is transferred from the curing station to the trolley, and the or each green tire blank is transferred from the trolley to the curing station;
- le chariot se déplace ensuite en transportant le ou chaque pneumatique cuit hors de la zone, le chariot demeurant dans la zone de chargement entre les deux étapes de transport. - the carriage then moves by transporting the or each cured tire out of the zone, the carriage remaining in the loading zone between the two transport stages.
[0004] De la sorte, le chariot transporte toujours une charge et son utilisation est optimisée. [0004] In this way, the carriage always carries a load and its use is optimized.
[0005] Toutefois, l’installation permettant la mise en œuvre d’un tel procédé est complexe et son implantation requiert un espace au sol important. [0005] However, the installation allowing the implementation of such a method is complex and its installation requires a large floor space.
[0006] Par ailleurs, le support adapté aux ébauches crues de pneumatique comprend un élément apte à venir en appui avec la partie interne du bourrelet supérieur de l’ébauche crue. Un tel système est lourd et encombrant ce qui contraint la conception du chariot et pénalise ses performances dynamiques. [0006] Furthermore, the support suitable for green tire blanks comprises an element capable of coming into contact with the internal part of the upper bead of the green tire blank. Such a system is heavy and bulky, which constrains the design of the carriage and penalizes its dynamic performance.
[0007] Enfin, si le chariot n’est pas disponible au poste de cuisson dès que la cuisson d’un premier pneumatique est achevée, la cuisson d’un deuxième pneumatique ne peut être initiée rapidement. Autrement dit, le temps net d’utilisation du poste de cuisson est réduit, et son rendement est dégradé. [0007] Finally, if the trolley is not available at the curing station as soon as the curing of a first tire is completed, the curing of a second tire cannot be initiated. rapidly. In other words, the net time of use of the cooking station is reduced, and its performance is degraded.
[0008] Un objectif de l’invention est de remédier aux inconvénients de l’état de la technique et d’apporter une solution permettant l’amélioration du transport des pneumatiques cuits et/ou des ébauches crues de pneumatique. [0008] An object of the invention is to remedy the drawbacks of the state of the art and to provide a solution allowing the improvement of the transport of cured tires and/or green tire blanks.
[0009] A cette fin, l’invention propose un procédé de transport de pneumatiques au moyen d'une installation de transport de pneumatiques comprenant un organe de transport, un premier organe de stockage de pneumatiques cuits, et un poste de cuisson de pneumatiques, caractérisé en ce que : [0009] To this end, the invention proposes a method for transporting tires by means of a tire transport installation comprising a transport member, a first member for storing cured tires, and a tire curing station, characterized in that:
- on transfère au moins un pneumatique cuit du premier organe de stockage à l'organe de transport dans une zone de chargement de l'organe de transport, - at least one cured tire is transferred from the first storage member to the transport member in a loading zone of the transport member,
- l’organe de transport se déplace en transportant le ou chaque pneumatique cuit hors de la zone de chargement de l'organe de transport, - the transport member moves by transporting the or each cured tire out of the loading zone of the transport member,
- on transfère au moins un pneumatique cuit du poste de cuisson au premier organe de stockage dans une zone de déchargement du poste de cuisson. - At least one cured tire is transferred from the curing station to the first storage member in an unloading zone of the curing station.
[0010] Un tel procédé est particulièrement adapté aux postes de cuisson du type « à flux traversant » dans lesquels les ébauches crues sont chargées par l’avant du poste de cuisson et les pneumatiques cuits sont déchargés par l’arrière dudit poste. [0010] Such a method is particularly suitable for curing stations of the "cross-flow" type in which the green blanks are loaded from the front of the curing station and the cured tires are unloaded from the rear of the said station.
[0011] Par ailleurs, le premier organe de stockage permet d’augmenter le temps net d’utilisation du poste de cuisson, autrement dit, son rendement. [0011] Furthermore, the first storage member makes it possible to increase the net time of use of the cooking station, in other words, its performance.
[0012] De préférence, l’installation de transport comprend un deuxième organe de stockage d’ébauches crues de pneumatique, et, préalablement aux étapes de transfert d’un pneumatique cuit, [0012] Preferably, the transport installation comprises a second storage device for raw tire blanks, and, prior to the steps of transferring a cured tire,
- l’organe de transport se déplace en transportant au moins une ébauche crue de pneumatique jusqu'à une zone de déchargement de l'organe de transport, l'organe de transport demeurant dans ladite zone entre les deux étapes de transport, - the transport member moves by transporting at least one raw tire blank to an unloading zone of the transport member, the transport member remaining in said zone between the two transport stages,
- on transfère au moins une ébauche crue de pneumatique de l'organe de transport au deuxième organe de stockage dans la zone de déchargement de l'organe de transport, et, successivement aux étapes de transfert d'un pneumatique cuit, - at least one green tire blank is transferred from the transport member to the second storage member in the unloading zone of the transport member, and, successively to the steps of transferring a cured tire,
- on transfère au moins une ébauche crue de pneumatique du deuxième organe de stockage au poste de cuisson dans une zone de chargement du poste de cuisson. - At least one green tire blank is transferred from the second storage member to the cooking station in a loading zone of the cooking station.
[0013] Un tel procédé est particulièrement adapté aux postes de cuisson du type à chargement des ébauches crues ou à déchargement des pneumatiques cuits, par l’arrière du poste de cuisson, l’accès à l’avant du poste de cuisson étant alors réservé, par exemple, aux opérations de chargement ou de déchargement des moules de cuisson. [0013] Such a method is particularly suitable for cooking stations of the type for loading raw blanks or unloading cured tires, from the rear of the cooking station, access to the front of the cooking station then being reserved , for example, to the operations of loading or unloading baking moulds.
[0014] Par ailleurs, l’organe de transport peut décharger une ébauche crue et charger un pneumatique cuit sans attendre. Ainsi, la combinaison des premier et deuxième organes de stockage permet d’augmenter le temps net d’utilisation de l’organe de transfert, autrement dit, son rendement. [0014] Furthermore, the transport member can unload a raw blank and load a cured tire without waiting. Thus, the combination of the first and second storage members makes it possible to increase the net time of use of the transfer member, in other words, its efficiency.
[0015] Avantageusement, les étapes de transfert entre l’organe de transport et les premier et deuxième organes de stockage sont opérées par une pince de l'organe de transport. [0015] Advantageously, the transfer steps between the transport member and the first and second storage members are operated by a clamp of the transport member.
[0016] Un tel agencement permet d’opérer efficacement les étapes de transfert, tout en simplifiant les premier et deuxième organes de stockage. [0016] Such an arrangement makes it possible to operate the transfer steps efficiently, while simplifying the first and second storage members.
[0017] De préférence, le premier organe de stockage comprend un support d'un pneumatique cuit mobile entre une position de chargement alignée verticalement avec la zone de déchargement du poste de cuisson, et une position de déchargement alignée verticalement avec la zone de chargement de l'organe de transport, le deuxième organe de stockage comprend un support d'ébauche crue de pneumatique mobile entre une position de chargement alignée verticalement avec la zone de déchargement de l’organe de transport, et une position de déchargement alignée verticalement avec la zone de chargement du poste de cuisson, et, préalablement aux étapes de transport, on ramène la pince de l’organe de transport verticalement au-dessus des supports d’ébauche crue et/ou de pneumatique cuit, à une distance équivalente à une largeur maximale prédéterminée d’une ébauche crue ou d’un pneumatique cuit et, de préférence, à une distance de 700 mm. [0018] Ainsi, le débattement et les déplacements de la pince de l’organe de transport sont optimisés et la durée des étapes de transfert est réduite. [0017] Preferably, the first storage member comprises a support for a cured tire that is movable between a loading position aligned vertically with the unloading zone of the curing station, and an unloading position aligned vertically with the loading zone of the the transport member, the second storage member comprises a green tire blank support movable between a loading position aligned vertically with the unloading zone of the transport member, and an unloading position aligned vertically with the zone loading of the curing station, and, prior to the transport steps, the gripper of the transport member is brought back vertically above the supports for the uncured blank and/or the cured tire, at a distance equivalent to a maximum width predetermined distance from a raw blank or a cured tire and preferably at a distance of 700 mm. [0018] Thus, the clearance and movements of the gripper of the transport member are optimized and the duration of the transfer steps is reduced.
[0019] Avantageusement, on déplace l'organe de transport le long d'une voie dédiée au guidage mécanique dudit organe. [0019] Advantageously, the transport member is moved along a path dedicated to the mechanical guiding of said member.
[0020] De préférence, les opérations de transfert entre les premier et deuxième organes de stockage et le poste de cuisson sont opérées par une pince du poste de cuisson. [0020] Preferably, the transfer operations between the first and second storage members and the cooking station are carried out by a clamp of the cooking station.
[0021] Un tel agencement permet d’opérer efficacement les étapes de transfert, tout en simplifiant les premier et deuxième organes de stockage. [0021] Such an arrangement makes it possible to operate the transfer steps efficiently, while simplifying the first and second storage members.
[0022] De préférence, l’installation de transport comprend un circuit de refroidissement, et, préalablement aux étapes de transport, on ramène la pince de l’organe de transport verticalement au-dessus du circuit de refroidissement à une distance équivalente à une largeur maximale prédéterminée d'une ébauche crue ou d’un pneumatique cuit et, de préférence, à une distance de 700 mm. [0022] Preferably, the transport installation comprises a cooling circuit, and, prior to the transport steps, the gripper of the transport member is brought back vertically above the cooling circuit at a distance equivalent to a width predetermined maximum of a raw blank or a cured tire and, preferably, at a distance of 700 mm.
[0023] Ainsi, le débattement et les déplacements de la pince de l’organe de transport sont optimisés et la durée des étapes de transfert est réduite. [0023] Thus, the clearance and movements of the gripper of the transport member are optimized and the duration of the transfer steps is reduced.
[0024] L’invention a également pour objet une installation de transport de pneumatiques mise en œuvre lors du procédé de transport selon un précédent objet de l’invention. [0024] Another subject of the invention is a tire transport installation implemented during the transport process according to a previous subject of the invention.
[0025] Une telle installation occupe une surface au sol réduite et permet le transport des ébauches crues de pneumatique ou des pneumatiques cuits, respectivement, à destination ou en provenance d’un poste de cuisson de pneumatiques, de manière plus efficace et rapide. [0025] Such an installation occupies a reduced floor area and allows the transport of raw tire blanks or cured tires, respectively, to or from a tire curing station, more efficiently and quickly.
[0026] De préférence, le poste de cuisson, les zones de chargement ou de déchargement de l'organe de transport, et les zones de chargement ou de déchargement du poste de cuisson sont distantes les unes des autres au plus de 3 m, plus préférentiellement, au plus 2 m et, encore plus préférentiellement, au plus de 1 m. [0026] Preferably, the cooking station, the loading or unloading areas of the transport member, and the loading or unloading areas of the cooking station are spaced apart from each other at most 3 m, more preferentially, at most 2 m and, even more preferentially, at most 1 m.
[0027] Selon un mode de réalisation préférentielle, les premier et deuxième organes de stockage sont superposés de telle manière que les zones de chargement et de déchargement de l’organe de transport sont confondues, et que les zones de chargement et de déchargement du poste de cuisson sont également confondues. [0028] Une telle implantation de l’installation de transport est simple et compacte. [0027] According to a preferred embodiment, the first and second storage members are superposed in such a way that the loading and unloading zones of the transport member coincide, and the loading and unloading zones of the station of cooking are also confused. [0028] Such a layout of the transport installation is simple and compact.
[0029] Selon une variante du mode de réalisation précédent, les zones de chargement et de déchargement de l’organe de transport et les zones de chargement et de déchargement du poste de cuisson sont identiques. Autrement dit, un organe de stockage se décale afin de permettre l’accès au support de l’autre organe de stockage, par la pince de l’organe de stockage ou par la pince du poste de cuisson. According to a variant of the previous embodiment, the loading and unloading zones of the transport member and the loading and unloading zones of the cooking station are identical. In other words, a storage member shifts in order to allow access to the support of the other storage member, by the clamp of the storage member or by the clamp of the cooking station.
[0030] Une telle implantation de l’installation de transport est encore plus compacte. [0030] Such a layout of the transport installation is even more compact.
[0031] De préférence, la voie de guidage de l'organe de transport est agencée au-dessus de l’organe de transport. [0031] Preferably, the guide track of the transport member is arranged above the transport member.
[0032] Une telle implantation de l’installation de transport améliore l’accessibilité de l’installation et permet encore de réduire la surface au sol de ladite installation. [0032] Such a location of the transport installation improves the accessibility of the installation and further reduces the floor area of said installation.
[0033] Avantageusement, les premier et deuxième organes de stockage sont agencés entre les zones de chargement ou de déchargement de l'organe de transport, et les zones de chargement ou déchargement du poste de cuisson. Advantageously, the first and second storage members are arranged between the loading or unloading zones of the transport member, and the loading or unloading zones of the cooking station.
[0034] De préférence, le circuit de refroidissement est adjacent à la zone de chargement ou déchargement de l’organe de transport. [0034] Preferably, the cooling circuit is adjacent to the loading or unloading zone of the transport member.
[0035] L’invention sera mieux comprise grâce à la suite de la description, qui s’appuie sur les figures suivantes : The invention will be better understood thanks to the rest of the description, which is based on the following figures:
- la figure 1 est une vue de dessus illustrant certains éléments d’une installation de transport de pneumatiques ; - Figure 1 is a top view illustrating certain elements of a tire transport installation;
- la figure 2 est une vue en perspective illustrant certains éléments de l’installation de la figure 1. - Figure 2 is a perspective view illustrating certain elements of the installation of Figure 1.
[0036] On a illustré aux figures 1 et 2 une installation de transport 10 de pneumatiques. Une installation de transport de pneumatiques comprend notamment : un organe de transport 12, destiné à déplacer des ébauches crues 13 de pneumatique ou des pneumatiques cuits 14, respectivement, à destination ou en provenance d’un poste de cuisson de pneumatiques ; un premier organe de stockage 15 de pneumatiques cuits ; un deuxième organe de stockage 16 d’ébauches crues de pneumatique ; et le poste de cuisson 18 de pneumatiques. [0037] Par poste de cuisson 18, on entend l’emplacement aménagé pour la cuisson des pneumatiques. Le poste de cuisson comprend une presse de cuisson 20 qui comporte une face avant au voisinage de laquelle est disposé un boitier de commande de la presse de cuisson, et une face arrière. A l’issue de la cuisson d’une ébauche crue de pneumatique, la presse de cuisson s’ouvre, puis le pneumatique cuit est démoulé et positionné de manière adaptée à son prochain déchargement par la face arrière. There is illustrated in Figures 1 and 2 a transport installation 10 of tires. A tire transport installation comprises in particular: a transport member 12, intended to move green tire blanks 13 or cured tires 14, respectively, to or from a tire curing station; a first storage member 15 for cured tires; a second storage device 16 for green tire blanks; and the tire curing station 18. [0037] By cooking station 18, we mean the location arranged for the cooking of the tires. The cooking station comprises a cooking press 20 which comprises a front face in the vicinity of which is arranged a control box for the cooking press, and a rear face. At the end of the curing of a green tire blank, the curing press opens, then the cured tire is removed from the mold and positioned in a manner suitable for its next unloading via the rear face.
[0038] A titre d’exemple, les postes de cuisson 18 sont implantés au sol de manière à former plusieurs lignes 22, 23, comportant des dispositifs communs, tel un circuit de refroidissement. For example, the cooking stations 18 are located on the ground so as to form several lines 22, 23, comprising common devices, such as a cooling circuit.
[0039] L’installation de transport 10 comprend également une voie 24 dédiée au guidage mécanique de l’organe de transport 12. A titre d’exemple, l’organe de transport est un chariot guidé par des rails, des glissières ou tout autre guidage adapté. Le chariot peut être entrainé par un système à courroie crantée s’étendant le long de la voie de guidage, par une roue motrice du chariot, ou par tout autre entrainement adapté. The transport installation 10 also includes a track 24 dedicated to the mechanical guiding of the transport member 12. By way of example, the transport member is a carriage guided by rails, slides or any other appropriate guidance. The carriage can be driven by a toothed belt system extending along the guideway, by a drive wheel of the carriage, or by any other suitable drive.
[0040] La voie de guidage 24 de l'organe de transport 12 est agencée au-dessus de l'organe de transport. Autrement dit, la voie de guidage est aérienne et suspendue à une structure métallique 26. A titre d’exemple, la voie peut également être agencée essentiellement au- dessous de l’organe de transport ou, autrement dit, au sol. The guide track 24 of the transport member 12 is arranged above the transport member. In other words, the guide track is aerial and suspended from a metal structure 26. By way of example, the track can also be arranged essentially below the transport member or, in other words, on the ground.
[0041] L’organe de transport 12 comprend une pince (non illustrée) adaptée à la préhension d’ébauches crues de pneumatique ou de pneumatiques cuits. Ladite pince opère notamment les transferts des ébauches crues de pneumatique ou des pneumatiques cuits entre l’organe de transport et les premier et deuxième organes de stockage. Le chariot comprend un dispositif de positionnement qui coopère avec la pince pour l’amener en position de préhension. A titre d’exemple, le dispositif de positionnement de l’organe de transport est un bras manipulateur muni de pivots et/ou de glissières. De préférence, ledit dispositif prend la forme d’un palan 28 compact et léger, permettant ainsi à l’organe de transport 12 d’atteindre des performances dynamiques élevées, tout en conférant à ladite pince un débattement important. The transport member 12 comprises a gripper (not shown) suitable for gripping raw tire blanks or cured tires. Said gripper operates in particular the transfers of raw tire blanks or cured tires between the transport member and the first and second storage members. The carriage includes a positioning device which cooperates with the gripper to bring it into the gripping position. By way of example, the device for positioning the transport member is a manipulator arm fitted with pivots and/or slideways. Preferably, said device takes the form of a compact and light hoist 28, thus allowing the transport member 12 to achieve high dynamic performance, while giving said gripper significant travel.
[0042] Le poste de cuisson 18 comprend également une pince 30 adaptée à la préhension d’ébauches crues de pneumatique ou de pneumatiques cuits. Ladite pince opère notamment les transferts des ébauches crues de pneumatique ou des pneumatiques cuits entre le poste de cuisson 18 et les premier et deuxième organes de stockage 15, 16. Le dispositif de positionnement de la pince du poste de cuisson est un bras manipulateur prenant la forme d’une potence. The curing station 18 also includes a gripper 30 suitable for gripping raw tire blanks or cured tires. Said gripper operates in particular the transfers of raw tire blanks or cured tires between the curing station 18 and the first and second storage members 15, 16. The device for positioning the gripper of the curing station is a manipulator arm taking the form of a gallows.
[0043] De préférence, les pinces des organe de transfert et poste de cuisson sont du type « à doigts ». Une pince à doigts s’insère par le bourrelet supérieur dans l’ébauche crue ou le pneumatique cuit, puis, plusieurs doigts s’étendent radialement vers l’extérieur de la pince pour venir en contact avec la partie intérieure du bourrelet supérieur de l’ébauche crue ou du pneumatique cuit. [0043] Preferably, the clamps of the transfer member and cooking station are of the "finger" type. A finger gripper is inserted via the upper bead into the green blank or the cured tire, then several fingers extend radially outwards from the gripper to come into contact with the inner part of the upper bead of the raw blank or cured tyre.
[0044] L’installation de transport comprend un circuit de refroidissement 32 destiné au refroidissement des pneumatiques cuits, et prenant la forme d’un convoyeur qui permet le refroidissement à l’air ambiant de l’ensemble des pneumatiques cuits par plusieurs presses de cuisson, voire par l’ensemble des presses de cuisson de l’installation de transport de pneumatiques. [0044] The transport installation comprises a cooling circuit 32 intended for cooling the cured tires, and taking the form of a conveyor which allows the cooling in ambient air of all the tires cured by several curing presses , or even by all the curing presses of the tire transport installation.
[0045] Le circuit de refroidissement 32 est adjacent à une zone de chargement ou de déchargement 34 de l'organe de transport 12. A titre d’exemple, la pince de l'organe de transport peut être amenée verticalement au-dessus du circuit de refroidissement 32 à une distance équivalente à une largeur maximale prédéterminée d'une ébauche crue ou d’un pneumatique cuit et, de préférence, à une distance de 700 mm. De préférence, le circuit de refroidissement est aérien et supporté par une structure métallique éventuellement partagée avec la structure 26 supportant la voie de guidage 24 de l’organe de transport 12. The cooling circuit 32 is adjacent to a loading or unloading zone 34 of the transport member 12. For example, the clamp of the transport member can be brought vertically above the circuit cooling 32 at a distance equivalent to a predetermined maximum width of a raw blank or a cured tire and, preferably, at a distance of 700 mm. Preferably, the cooling circuit is aerial and supported by a metal structure possibly shared with the structure 26 supporting the guide track 24 of the transport member 12.
[0046] Les premier et deuxième organes de stockage 15, 16 sont agencés entre des zones de chargement ou de déchargement 34 de l’organe de transport 12, et des zones de chargement ou déchargement 36 du poste de cuisson 18. Par zones de chargement ou de déchargement, on entend les emplacements auxquels ont lieu les opérations de transfert. The first and second storage members 15, 16 are arranged between loading or unloading zones 34 of the transport member 12, and loading or unloading zones 36 of the cooking station 18. By loading zones or unloading means the locations at which the transfer operations take place.
[0047] Le premier organe de stockage 15 comprend un support d’un pneumatique cuit 38 mobile entre une position de chargement alignée verticalement avec la zone de déchargement 36 du poste de cuisson 18, et une position de déchargement alignée verticalement avec la zone de chargement 34 de l'organe de transport 12. A titre d’exemples, ledit support prend la forme d’un anneau tronconique ou, de préférence, d’un disque métallique, ou encore, de toute forme sur laquelle la partie extérieure du flanc inférieur d’un pneumatique cuit est apte à prendre appui. Ledit support peut également prendre une forme telle que ledit support est apte à s’insérer dans le pneumatique cuit par le bourrelet inférieur et à prendre appui essentiellement sur la partie interne du bourrelet supérieur. The first storage member 15 comprises a support for a cured tire 38 movable between a loading position aligned vertically with the unloading zone 36 of the cooking station 18, and an unloading position aligned vertically with the loading zone 34 of the transport member 12. By way of example, said support takes the form of a frustoconical ring or, preferably, of a disc metallic, or even of any shape on which the outer part of the lower sidewall of a cured tire is able to rest. Said support can also take a form such that said support is able to be inserted into the cured tire by the lower bead and to rest essentially on the internal part of the upper bead.
[0048] Le deuxième organe de stockage 16 comprend un support d'ébauche crue de pneumatique 40 mobile entre une position de chargement alignée verticalement avec la zone de déchargement 34 de l’organe de transport 12, et une position de déchargement alignée verticalement avec la zone de chargement 36 du poste de cuisson 18. A titre d’exemples, ledit support prend la forme d’un anneau tronconique, ou, de préférence, est telle que ledit support est apte à s’insérer dans l’ébauche crue de pneumatique par le bourrelet inférieur et à prendre appui essentiellement sur la partie interne du bourrelet supérieur et, éventuellement, du bourrelet inférieur. The second storage member 16 comprises a green tire blank support 40 movable between a loading position aligned vertically with the unloading zone 34 of the transport member 12, and an unloading position aligned vertically with the loading zone 36 of the cooking station 18. By way of example, said support takes the form of a frustoconical ring, or, preferably, is such that said support is able to be inserted into the green tire blank by the lower bead and to rest essentially on the internal part of the upper bead and, possibly, of the lower bead.
[0049] Les premier et deuxième organes de stockage 15, 16 sont superposés de telle manière que les zones de chargement et de déchargement 34 de l’organe de transport 12 sont confondues, et que les zones de chargement et de déchargement 36 du poste de cuisson 18 sont également confondues. Les premier et deuxième organes de stockage sont formés d’une colonne 42 commune et de deux dispositifs de positionnement 44, 45. De préférence, les dispositifs de positionnement des premier et deuxième organes de stockage sont des bras rotatifs permettant le positionnement angulaire dans un plan horizontal donné de leurs supports respectifs. A titre d’exemple, le support 38 et le bras rotatif 44 du premier organe de stockage 15 sont agencés au-dessus du support 40 et du bras rotatif 45 du deuxième organe de stockage 16. The first and second storage members 15, 16 are superposed in such a way that the loading and unloading zones 34 of the transport member 12 coincide, and the loading and unloading zones 36 of the cooking 18 are also confused. The first and second storage members are formed from a common column 42 and two positioning devices 44, 45. Preferably, the positioning devices of the first and second storage members are rotary arms allowing the angular positioning in a plane given horizontal from their respective supports. By way of example, support 38 and rotary arm 44 of first storage member 15 are arranged above support 40 and rotary arm 45 of second storage member 16.
[0050] Les zones de chargement ou déchargement 34 de l’organe de transport 12, les zones de chargement ou déchargement 36 du poste de cuisson 18 et le poste de cuisson 18, sont distants les uns des autres au plus de 3 m, plus préférentiellement, au plus de 2 m et, encore plus préférentiellement, au plus de 1 m. De préférence, les premier et deuxième organes de stockage 15, 16 sont agencés entre les zones de chargement ou de déchargement 34 de l'organe de transport 12, et les zones de chargement ou déchargement 36 du poste de cuisson 18.
