Description

L'invention concerne le domaine du planage des bandes ou des plaques métalliques épaisses. Elle concerne en particulier un dispositif de retournement d'un équipage de planage.The invention relates to the field of flattening strips or thick metal plates. It relates in particular to a device for turning over a planing equipment.

Le planage des bandes épaisses est obtenu par une succession de flexions alternées d'amplitude décroissante sans application de traction externe en amont ou en aval de la machine de planage. Ces machines de planage comportent deux équipages de planage portant chacun une série de rouleaux à axes parallèles placés respectivement au dessus et en dessous de la bande, les rouleaux étant décalés longitudinalement et verticalement, de façon à s'imbriquer en déterminant un trajet ondulé de la bande qui est ainsi soumise à des effets de flexions alternées successives. Ces flexions alternées se traduisent par des courbures générant dans la bande, des déformations qui varient d'un état de traction à l'extrados de la courbure à un état de compression à l'intrados, en passant par une valeur nulle dans l'axe médian ou « fibre neutre » de la bande, selon une loi de variation linéaire. Selon l'amplitude de la courbure, les contraintes ainsi générées peuvent dépasser la limite élastique de la bande sur une fraction plus ou moins importante de son épaisseur. Cette plastification est un élément décisif d'élimination des défauts de planéité non développables tels que les « bords longs », les « centres longs »... On exprime habituellement la fraction d'épaisseur de bande plastifiée en pourcentage de l'épaisseur totale qu'on désigne par le terme de « taux de plastification ».The planarization of the thick strips is obtained by a succession of alternating bends of decreasing amplitude without application of external traction upstream or downstream of the leveling machine. These leveling machines comprise two leveling equipments each carrying a series of rollers with parallel axes placed respectively above and below the band, the rollers being offset longitudinally and vertically, so as to interlock by determining a corrugated path of the band which is thus subjected to successive alternating bending effects. These alternating flexures result in curvatures generating in the band, deformations which vary from a traction state to the extrados of the curvature to a state of compression at the intrados, via a zero value in the axis. median or "neutral fiber" of the band, according to a law of linear variation. Depending on the amplitude of the curvature, the stresses thus generated may exceed the elastic limit of the band on a more or less significant fraction of its thickness. This plasticization is a decisive element for eliminating non-developable flatness defects such as "long edges", "long centers" ... The thickness fraction of the plasticized strip is usually expressed as a percentage of the total thickness that The term "plasticization ratio" is used.

D'une façon générale, chaque équipage de planage, respectivement inférieur ou supérieur, comporte une pluralité de rouleaux à axes parallèles qui ont, normalement, un diamètre réduit et sont donc soutenus par au moins deux rouleaux de soutien qui peuvent eux-mêmes prendre appui sur des rangées de galets, l'ensemble de ces rouleaux et galets étant assemblés sur un châssis.In general, each leveling unit, respectively lower or upper, comprises a plurality of rollers with parallel axes which normally have a reduced diameter and are therefore supported by at least two supporting rollers which can themselves bear on rows of rollers, all of these rollers and rollers being assembled on a frame.

Ces deux équipages de planage, placés respectivement en-dessous et au-dessus d'un plan horizontal de défilement de la bande, sont placés dans un bâti de support comportant quatre colonnes disposées de part et d'autre de l'axe longitudinal de défilement de la bande, solidarisées à leur partie inférieure par un sommier fixe et à leur partie supérieure par des poutres transversales, l'ensemble formant un cadre fermé.These two planing crews, placed respectively below and above a horizontal plane of travel of the band, are placed in a support frame comprising four columns arranged on either side of the longitudinal axis of scrolling of the band, secured at their lower part by a fixed bed base and at their upper part by transverse beams, the assembly forming a closed frame.

L'équipage de planage inférieur prend appui sur le sommier fixe et, l'équipage supérieur prend appui sur un cadre de pression qui peut être déplacé verticalement entre les quatre colonnes au moyen de vérins mécaniques ou hydrauliques prenant appui sur la partie supérieure du bâti, de façon à régler l'écartement des deux équipages de planage et, par conséquent, l'imbrication des rouleaux, en reprenant les efforts d'écartement dus à la résistance du produit.The lower leveling crew is supported on the fixed bed and the upper crew is supported on a pressure frame that can be moved vertically between the four columns by means of mechanical or hydraulic cylinders supported on the upper part of the frame, so as to adjust the spacing of the two planing crews and, therefore, the nesting of the rollers, by taking up the spacing forces due to the strength of the product.

La publication EP-A-1918ø36 divolgue un dispositif avec tels équipages de planage.The publication EP-1918ø36 divolve a device with such planing crews.

Habituellement, certains au moins des rouleaux de planage sont entraînés en rotation autour de leurs axes afin de faire avancer la bande, par frottement, à une vitesse déterminée, en suivant un trajet ondulé entre les rouleaux inférieurs et supérieurs.Usually, at least some of the leveling rollers are rotated about their axes in order to advance the web by friction at a determined speed, following a corrugated path between the lower and upper rollers.

Durant l'opération de planage, les rouleaux subissent de fortes contraintes de pression superficielle et des phénomènes d'abrasion qui nécessitent leur remise en état, par exemple un usinage par rectification de leurs surfaces actives, dans un atelier de maintenance. Dans ce contexte, les équipages de planage supérieur et inférieur doivent être extirpés de la machin de planage. L'équipage de planage inférieur ayant ses rouleaux de planage dirigés vers le haut pourra facilement être rectifié. Toutefois, l'équipage de planage supérieur ayant ses rouleaux de planage dirigés vers le bas doit tout d'abord être retourné afin que des opérateurs puissent avoir accès à ses rouleaux de planage.During the planing operation, the rollers are subjected to high surface pressure stresses and abrasion phenomena that require their repair, for example machining by grinding their active surfaces, in a maintenance workshop. In this context, the upper and lower planing crews must be removed from the planing machine. The lower leveling unit with its planing rollers facing upwards can easily be rectified. However, the upper leveling crew with its downward facing rollers must first be returned so that operators can access the planing rollers.

La publication WO2008/099126 divulgue un dispositif de retournement d'un équipage de planage supérieur d'une machine de planage. L'équipage de planage est dans un premier temps extrait de la machine de planage et pris en charge par un palonnier de manutention. Le palonnier de manutention est ensuite placé sur un berceau. Durant toutes ces étapes, les rouleaux de l'équipage de planage supérieur ne sont pas accessibles aux opérateurs et les opérations de réparation proprement dites ne peuvent pas commencer. Le palonnier de manutention est monté rotatif sur un berceau autour de tourillons et peut pivoter autour d'un axe horizontal de manière à entraîner en rotation l'équipage de planage supérieur. Ce n'est qu'à la fin de cette ultime étape que les rouleaux de planage de l'équipage de planage supérieur deviennent accessibles.The publication WO2008 / 099126 discloses a device for turning over a top leveling machine of a leveling machine. The leveling crew is initially extracted from the leveling machine and taken over by a lifting beam. The lifting beam is then placed on a cradle. During all these stages, the rolls of the upper planing crew are not accessible to the operators and the repair operations themselves can not begin. The handling bar is rotatably mounted on a cradle around pins and is pivotable about a horizontal axis so as to rotate the upper leveling crew. It is only at the end of this final stage that the planing rollers of the upper leveling crew become accessible.

Ces opérations de retournement demandent l'exécution de nombreuses opérations réalisées par des opérateurs dans un environnement potentiellement dangereux. Les opérateurs doivent en particulier manoeuvrer le palonnier de manutention et le berceau support des rouleaux de planage qui peuvent être à des températures élevées. En outre, un grand nombre de manipulations et d'opérations successives doivent être réalisées.These flipping operations require the execution of many operations performed by operators in a potentially dangerous environment. In particular, the operators must operate the handling beam and the support cradle of the leveling rollers, which may be at high temperatures. In addition, a large number of manipulations and successive operations must be performed.

Il existe donc un besoin d'un moyen de retournement simple, nécessitant le moins possible d'intervention d'opérateurs et réalisant le retournement le plus rapidement possible et avec le moins d'étapes possibles.There is therefore a need for a simple reversal means, requiring the least possible operator intervention and performing the reversal as quickly as possible and with the least possible steps.

Dans ce but, l'invention a pour objet un dispositif de retournement d'un équipage de planage, l'équipage de planage comportant une pluralité de rouleaux espacés les uns des autres et montés rotatifs sur un châssis et des moyens pour son arrimage au dispositif de retournement, le dispositif de retournement étant caractérisé en ce qu'il comporte :

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture d'un mode de réalisation détaillé, non limitatif, faite en référence aux figures sur lesquelles :

Other features and advantages of the present invention will appear on reading a detailed, non-limiting embodiment, with reference to the figures in which:
  • the figure 1 is a perspective view of a turning device according to the invention and a set of planing equipments located outside the turning device,
  • the figures 2 , 3 and 5 to 7 are successive views of the steps of turning one of the planing crews, by the device according to the invention from the position of the figure 1 ,
  • the figure 4 is a rear view of the turning device of the figure 1 carrying one of the planing crews in a high position.

La figure 1 est une vue en perspective d'un dispositif de retournement 10 selon l'invention et d'un ensemble comportant un équipage de planage supérieur 20 posé sur un équipage de planage inférieur 46. Les équipages de planage 20 et 46 comportent chacun un châssis repéré respectivement 44 et 48. Chaque châssis 44, 46 reçoit pluralité de rouleaux de planage montés rotatifs et repérés respectivement 43 et 42 sur la figure 1. Tel que représenté sur la figure 1, l'ensemble formé par les équipages de planage 20 et 46 a été préalablement sortie d'une machine de planage (non représenté sur les figures) afin que les rouleaux de planage soient changés ou rectifiés. Lorsque l'équipage de planages supérieur 20 est solidarisé à l'équipage de planage inférieur 46, les opérateurs n'ont pas accès aux rouleaux de planage 42 et 43 et toute opération de changement ou de rectification des équipages de planage 42 et 43 est donc impossible. Il faut donc pouvoir désolidariser l'équipage de planage supérieur 20 de l'équipage de planage inférieur 46.The figure 1 is a perspective view of a turning device 10 according to the invention and an assembly comprising an upper planing unit 20 placed on a lower planing unit 46. The leveling crews 20 and 46 each comprise a frame respectively marked 44 and 48. Each frame 44, 46 receives a plurality of rotating planing rollers rotatably mounted and respectively marked 43 and 42 on the figure 1 . As shown on the figure 1 , the assembly formed by the leveling crews 20 and 46 was previously removed from a leveling machine (not shown in the figures) so that the planing rollers are changed or rectified. When the upper planing crew 20 is secured to the lower leveling crew 46, the operators do not have access to the planing rollers 42 and 43 and any change or correction operation of the leveling crews 42 and 43 is therefore impossible. It must therefore be possible to dissociate the upper leveling crew 20 from the lower leveling crew 46.

A cette fin, l'équipage de planage supérieur 20 comporte des moyens pour son arrimage au dispositif de retournement 10. Plus précisément, les moyens d'arrimage de l'équipage de planage 20 comportent une pluralité de crochets 22 solidaires du châssis 44 et destinés à coopérer avec des moyens d'arrimage 40 du dispositif de retournement. Tel que cela est visible à la figure 1, l'extrémité libre de chaque crochet 22 est dirigée vers le bas avant l'introduction de l'équipage de planage 20 dans le dispositif de retournement 10.To this end, the upper planing unit 20 comprises means for securing it to the turning device 10. More specifically, the leveling crew of the leveling equipment 20 comprise a plurality of hooks 22 secured to the frame 44 and intended to to cooperate with securing means 40 of the turning device. As it is visible in the figure 1 , the free end of each hook 22 is directed downwards before the introduction of the leveling equipment 20 into the turning device 10.

Chaque crochet 22 de l'équipage de planage est positionné de manière à prendre appui sur un des crochets 40 du dispositif de retournement 10 lorsque l'équipage de planage est complètement inséré dans le dispositif de retournement 10, comme cela sera explicité ultérieurement. Les crochets 22 définissent un passage pour les crochets 40 du dispositif de retournement, ces derniers servants également de guides à l'équipage de planage supérieur lors de son introduction dans le dispositif de retournement 10. Les crochets 22 sont regroupés par paire, chaque paire de crochet 22 se trouvant sensiblement au sommet d'un rectangle imaginaire de longueur et de largeur prédéterminées. Les crochets 22 d'une même paire s'étendent parallèlement l'un à l'autre à partir d'une face verticale du châssis 44 de l'équipage de planage supérieur 20.Each hook 22 of the leveling equipment is positioned so as to bear on one of the hooks 40 of the turning device 10 when the leveling equipment is completely inserted into the turning device 10, as will be explained later. The hooks 22 define a passage for the hooks 40 of the overturning device, the latter also serving as guides to the upper planing crew when it is introduced into the turning device 10. The hooks 22 are grouped in pairs, each pair of hook 22 being substantially at the top of an imaginary rectangle of predetermined length and width. The hooks 22 of the same pair extend parallel to each other from a vertical face of the chassis 44 of the upper planing equipment 20.

L'ensemble formé par les deux équipages de planage est posé sur une plateforme de transfert 50 elle-même posée sur des rails de convoyage 52. Cette plateforme 50 est liée à un vérin de transfert 54 capable de pousser la plateforme 50 à partir d'une position dans laquelle l'ensemble formé par les deux équipages de planage 20 et 46 est situé hors du dispositif de retournement, jusqu'à une position dans laquelle l'équipage de planage supérieur 20 est pris en charge par le dispositif de retournement 10, comme cela sera explicité ultérieurement.The assembly formed by the two planing crews is placed on a transfer platform 50 itself placed on the conveyor rails 52. This platform 50 is linked to a transfer cylinder 54 capable of pushing the platform 50 from a position in which the assembly formed by the two planing crews 20 and 46 is located outside the turning device, to a position in which the upper leveling crew 20 is supported by the turning device 10, as will be explained later.

Comme cela peut être vu sur les figures 1 et 4, le dispositif de retournement selon l'invention comporte deux montants 12 s'étendant verticalement à partir d'un socle 14, des moyens de support et d'arrimage 16 de l'équipage de planage supérieur 20 destinés à coopérer avec les moyens d'arrimage 22 de l'équipage de planage 20, les moyens de support et d'arrimage 16 étant disposés entre les montants 12. Le dispositif de retournement comporte en outre des moyens 19 d'entrainement en rotation des moyens 16 de support et d'arrimage, autour d'un axe horizontal entre une position première position dans laquelle, lorsque l'équipage de planage 20 est lié au dispositif de retournement, les rouleaux 42 de l'équipage de planage 20 sont orientés vers le bas, et une deuxième position dans laquelle les rouleaux 42 de l'équipage de planage 20 sont orientés vers le haut, comme cela sera expliqué ultérieurement. Le dispositif de retournement 10 comporte également des moyens 18 d'entrainement en translation verticale des moyens de support et d'arrimage 16.

The turning device further comprises means 19 for rotating the means 16 for support and stowage around a horizontal axis between a first position position in which, when the planing equipment 20 is connected to the turning device, the rollers 42 of the planing equipment 20 are oriented downwards, and a second position in which the rollers 42 of the planing equipment 20 are oriented upwards, as will be explained later. The turning device 10 also comprises means 18 for training in vertical translation of the supporting and securing means 16. Each driving means 18 is connected to one of the uprights 14.

Les montants 14 sont installés en vis-à-vis l'un de l'autre et son écartées d'une distance permettant l'insertion d'un ensemble d'équipages de planage 20, 46. Chaque montant support 14 comporte deux bras 24 disposés en vis-à-vis l'un de l'autre et s'étendant verticalement à partir du socle 14. Chaque bras 24 comporte des ailettes 24A de forme triangulaire s'étendant verticalement à partir du socle 14 et solidaires d'une portion droite verticale 24B. Chaque bras 24 comporte également sur la face interne de chaque portion droite 24B au moins un rail de guidage 26 des moyens 18 d'entrainement en translation verticale des moyens de support et d'arrimage 16.The uprights 14 are installed vis-à-vis one another and spaced a distance allowing the insertion of a set of planing crews 20, 46. Each support post 14 comprises two arms 24 disposed opposite each other and extending vertically from the base 14. Each arm 24 has triangular fins 24A extending vertically from the base 14 and integral with a portion vertical straight 24B. Each arm 24 also has on the inner face of each straight portion 24B at least one guide rail 26 means 18 for driving in vertical translation means for supporting and securing 16.

Selon l'invention, les moyens 18 d'entrainement en translation verticale des moyens de support et d'arrimage 16 et donc de l'équipage de planage supérieur 20 comportent des axes d'entraînement en translation 38 s'étendant chacun verticalement et parallèlement entre les deux bras 24 de chaque montant 12. De manière préférée, deux axes d'entraînement en translation 38 cylindriques sont installés par montant. Les moyens d'entraînement en translation comportent également deux coulisseaux 18 recevant chacun deux des axes d'entraînement en translation 38 pour leur entraînement en translation verticale, chaque coulisseau 18 étant apte à monter ou descendre le long des axes 38 d'entraînement qu'il reçoit sous l'action d'un dispositif d'entraînement qui peut être internes à chaque coulisseau 18. Les axes d'entraînement en translation 38 peuvent faire partie de vérins à vis. Chaque coulisseau est positionné entre les bras 24 d'un montant 12 et est guidé en translation par deux rails 26. Les moyens 18 d'entrainement en translation verticale peuvent comporter d'autres type de dispositif d'entrainement, tels que d'autres types de vérins, des systèmes à vis/écrous ou à pignons/crémaillères ou encore des chaines.According to the invention, the means 18 for driving in vertical translation of the support and stowage means 16 and thus of the upper planing equipment 20 comprise translational drive shafts 38 each extending vertically and in parallel between the two arms 24 of each post 12. Preferably, two cylindrical translation drive axes 38 are installed per post. The drive means in translation also comprise two sliders 18 each receiving two translation drive shafts 38 for their drive in vertical translation, each slider 18 being able to ascend or descend along the drive axes 38 that it receives under the action of a driving device which may be internal to each slide 18. The translation drive shafts 38 may be part of screw jacks. Each slider is positioned between the arms 24 of an upright 12 and is guided in translation by two rails 26. The vertical translation drive means 18 may comprise other types of training device, such as other types. cylinders, screw / nut or rack / pinion systems or chains.

Le dispositif de retournement 10 de l'équipage de planage supérieur 20 comporte des moyens de support et d'arrimage comportant un châssis 16. Le châssis 16 comporte deux traverses horizontales 28 s'étendant longitudinalement et parallèlement entre les montants 12. Les traverses sont liées entre elles par deux barres transversales 30. Les traverses 28 et les barres transversales 30 s'étendent dans un plan perpendiculaire aux plans contenant les montants 12. La longueur de chaque barre transversale est supérieure à la longueur de l'ensemble formé par les équipages de planage supérieur 20 et inférieur 46.The overturning device 10 of the upper leveling crew 20 comprises support and stowage means comprising a frame 16. The frame 16 comprises two horizontal crosspieces 28 extending longitudinally and parallel between the uprights 12. The sleepers are linked between them by two transverse bars 30. The crosspieces 28 and the transverse bars 30 extend in a plane perpendicular to the planes containing the uprights 12. The length of each transverse bar is greater than the length of the assembly formed by the crews of top planing 20 and bottom 46.

Le châssis 16 comporte également deux pièces de maintien 32 placées en vis-à-vis l'une de l'autre qui reçoivent chacune une des extrémités de chaque traverse 28, ces pièces de maintien 32 sont également solidaires des moyens 18 d'entrainement en translation des moyens de support et d'arrimage 16. Plus précisément, dans le mode de réalisation représenté aux figures 1 à 7, chaque pièce de maintien 32 est solidaire d'un coulisseau 18 et est entraîné en translation verticale par ce coulisseau 18. Chaque pièce de maintien 32 s'étend au moins partiellement en dessous des traverses 28 et comporte une portion en forme U formant support des traverses 28 et recevant une des extrémités de chaque traverse 28.The frame 16 also comprises two holding pieces 32 placed facing each other, each receiving one end of each crosspiece 28, these holding pieces 32 are also integral with the drive means 18. translation of the support and docking means 16. More specifically, in the embodiment shown in FIGS. Figures 1 to 7 each holding piece 32 is integral with a slider 18 and is driven in vertical translation by the slider 18. Each holding piece 32 extends at least partially below the cross-members 28 and comprises a U-shaped portion forming a support for the slats. cross members 28 and receiving one end of each cross member 28.

Les moyens de support et d'arrimage 16 comportent une pluralité de crochets 40 s'étendant chacun à partir d'une des pièces de maintien 32 en dessous d'une traverse 28, l'extrémité libre 41 de chaque crochet 40 étant dirigée vers le haut lorsque le dispositif de retournement 10 est dans sa première position. Chaque crochet 40 est positionné pour que la distance entre son extrémité libre 41 et la face inférieure de la traverse horizontale 28 qui lui est la plus proche autorise le passage des moyens d'arrimage 22 appartenant à l'équipage de planage 20, et le blocage cet équipage de planage 20.The support and securing means 16 comprise a plurality of hooks 40 each extending from one of the holding pieces 32 below a crosspiece 28, the free end 41 of each hook 40 being directed towards the high when the turning device 10 is in its first position. Each hook 40 is positioned so that the distance between its free end 41 and the lower face of the horizontal crossbar 28 that is closest to it allows the passage securing means 22 belonging to the leveling crew 20, and blocking this planing unit 20.

En outre, chaque crochet 40 comporte à son extrémité libre une portion cylindrique 41 destinée à supporter et à guider les moyens d'arrimage 22 de l'équipage de planage 20 lors de son introduction dans le dispositif de retournement 10. Dans le mode de réalisation des figures 1 à 7, les crochets 40 sont au nombre de quatre et sont situés au sommet d'un rectangle imaginaire de longueur et de largeur prédétermiées.In addition, each hook 40 has at its free end a cylindrical portion 41 for supporting and guiding the lashing means 22 of the planing member 20 during its introduction into the turning device 10. In the embodiment of the Figures 1 to 7 , the hooks 40 are four in number and are located at the top of an imaginary rectangle of predetermined length and width.

Les moyens de support et d'arrimage 16 comportent des moyens de retenue pour l'arrêt en translation de l'équipage de planage 20 et pour la retenue de l'équipage de planage 20 lors de la rotation des moyens de support et d'arrimage 16. Les moyens de retenue comportent deux barres de blocage 36 en forme de L formant butée pour l'équipage de planage 20 lors de la rotation des moyens de support et d'arrimage 16. Chaque barre de blocage 36 est solidaire d'une barre transversale 30 et s'étend vers le bas à partir de cette barre transversale 30 lorsque le dispositif de retournement 10 est dans sa première position.The support and securement means 16 comprise retaining means for the translation stop of the leveling equipment 20 and for the retention of the planing equipment 20 during the rotation of the support and lashing means. 16. The retaining means comprise two L-shaped locking bars 36 forming a stop for the leveling crew 20 during the rotation of the support and stowage means 16. Each locking bar 36 is integral with a bar transverse 30 and extends downwardly from this cross bar 30 when the turning device 10 is in its first position.

Selon l'invention, le dispositif de retournement comporte également des moyens 19 d'entraînement en rotation des moyens de support et d'arrimage. Ces moyens 19 d'entraînement en rotation sont, dans le mode de réalisation des figures 1 à 7, portés par au moins un des coulisseaux 18. De manière avantageuse, chaque coulisseau 18 peut porter un moyen 19 d'entraînement en rotation des moyens de support et d'arrimage16. Plus précisément, chaque coulisseau 18 peut porter un moyen 19 d'entraînement en rotation horizontale du châssis 16 qui coopère avec un tourillon (non représenté sur la figure) d'une des pièces de maintien 32, l'actionnement de cet organe d'entraînement provoquant la rotation de la pièce de maintien 32 et donc du châssis 16. Le moyen d'entraînement 19 peut prendre la forme d'un motoréducteur ou d'un vérin (non représentés).According to the invention, the turning device also comprises means 19 for rotating the support and securing means. These rotating drive means 19 are, in the embodiment of the Figures 1 to 7 , carried by at least one of the sliders 18. Advantageously, each slider 18 may carry a means 19 for rotating the support and securing means 16. More specifically, each slider 18 may carry a horizontal rotation drive means 19 of the frame 16 which cooperates with a pin (not shown in the figure) of one of the holding pieces 32, the actuation of this drive member. causing the rotation of the holding piece 32 and thus the frame 16. The drive means 19 may take the form of a geared motor or a jack (not shown).

Afin de permettre un emboitement de chaque crochets 22 de l'équipage de planage supérieur 20 avec un crochets correspondant du dispositif de retournement 10, la largeur du rectangle imaginaire définissant la position des crochets 22 de l'équipage de planage 20 peut être inférieure ou égale à la largeur du rectangle imaginaire définissant la position des crochets 40 du dispositif de retournement 10.In order to allow interlocking of each hook 22 of the upper leveling crew 20 with a corresponding hook of the turning device 10, the width of the imaginary rectangle defining the position of the hooks 22 of the crew planing member 20 may be less than or equal to the width of the imaginary rectangle defining the position of the hooks 40 of the turning device 10.

On va à présent décrire les différentes étapes du retournement d'un équipage de planage 20 en référence aux figures 1 à 7, la position initiale étant celle représentée à la figure 1.We will now describe the different stages of the reversal of a planing crew 20 with reference to Figures 1 to 7 , the initial position being that represented in figure 1 .

Lors d'une première étape, les moyens d'entrainement en translation verticale des coulisseaux 18 sont commandés pour entraîner les coulisseaux 18 et donc le châssis 16 jusqu'à ce que les crochets 40 du châssis 16 soient positionnés en vis-à-vis des crochets 22 de l'équipage de planage supérieur 20 les plus proches du dispositif de retournement 10. Le vérin 54 pousse ensuite la plateforme 50 ce qui provoque la translation de l'ensemble composé des équipages de planage supérieur 20 et inférieur 46. Lors de cette translation, les deux premières paires de crochets 22 de l'équipage de planage supérieur 20 les plus proches du dispositif de retournement 10 s'engagent chacune sur la portion cylindrique 41 d'un des premiers cochets 40 appartenant au châssis 16. Chaque portion cylindrique 41 d'un premier cochet 40 appartenant au châssis 16 sert ainsi de guide en translation à l'ensemble formé par les deux équipages de planage supérieur 20 et inférieur 46. La translation se poursuit et les premières paires de crochets 22 de l'équipage de planage supérieur 20 avancent et dépassent les premiers cochets 40 appartenant au châssis 16. Chaque première paire de crochets 22 de l'équipage de planage supérieur 20 s'engage ensuite sur la portion cylindrique 41 d'un des seconds cochets 40 appartenant au châssis 16, les seconds crochets 40 (visibles sur la figure 4) étant situés à l'arrière du dispositif de retournement 10 dans le sens d'avancement de la plateforme 50. Simultanément, chaque seconde paire de crochets 22 de l'équipage de planage supérieur 20 s'engage sur la portion cylindrique 41 d'un des premiers cochets 40 appartenant au châssis 16. La translation se poursuit jusqu'à ce que l'ensemble formé par les deux équipages de planage supérieur 20 et inférieur 46 arrive en butée contre les deux barres de blocage 36 en forme de L. Dans cette position, chacun des crochets 22 de l'équipage de planage supérieur 20 est en prise avec un crochet 40 du dispositif de retournement 10 et, les rectangle imaginaires définissant respectivement la position des crochets 22 de l'équipage de planage supérieur 20 et la position des crochets complémentaires 40 du dispositif de retournement 10 sont superposés voire confondus, Il est donc possible que les rectangles imaginaires définissant respectivement la position des crochets 22 de l'équipage de planage supérieur 20 et la position des crochets complémentaires 40 du dispositif de retournement 10 aient les mêmes dimentions. On se retrouve alors dans la position représentée à la figure 2.In a first step, the drive means in vertical translation of the sliders 18 are controlled to drive the sliders 18 and thus the frame 16 until the hooks 40 of the frame 16 are positioned opposite the the hooks 22 of the upper planing unit 20 closest to the turning device 10. The cylinder 54 then pushes the platform 50 which causes the translation of the assembly composed of upper planing crews 20 and lower 46. During this translation, the first two pairs of hooks 22 of the upper leveling equipment 20 closest to the turning device 10 each engage on the cylindrical portion 41 of one of the first hooks 40 belonging to the frame 16. Each cylindrical portion 41 a first hook 40 belonging to the frame 16 thus serves as a guide in translation to the assembly formed by the two upper planing crews 20 and lower 46. The translation continues and the first pairs of hooks 22 of the upper leveling crew 20 advance and exceed the first hooks 40 belonging to the frame 16. Each first pair of hooks 22 of the upper leveling crew 20 then engages the portion cylindrical 41 of one of the second hooks 40 belonging to the frame 16, the second hooks 40 (visible on the figure 4 ) being located at the rear of the turning device 10 in the direction of travel of the platform 50. Simultaneously, each second pair of hooks 22 of the upper planing unit 20 engages the cylindrical portion 41 of a first sheaves 40 belonging to the frame 16. The translation continues until the assembly formed by the two upper planing crews 20 and lower 46 abuts against the two L-shaped locking bars 36. position, each of the hooks 22 of the upper leveling crew 20 is engaged with a hook 40 of the overturning device 10 and, the imaginary rectangle defining respectively the position of the hooks 22 of the upper leveling crew 20 and the position of the complementary brackets 40 of the reversal 10 are superimposed or even confused, It is therefore possible that the imaginary rectangles respectively defining the position of the hooks 22 of the upper leveling crew 20 and the position of the complementary hooks 40 of the turning device 10 have the same dimensions. We are then in the position represented in figure 2 .

Les moyens d'entrainement en translation verticale des coulisseaux 18 sont ensuite commandés pour entraîner les coulisseaux 18 et donc le châssis 16 vers le haut. L'équipage de planage supérieur 20 étant en prise avec le châssis 26 est également entraîné vers le haut et est désolidarisé d'avec l'équipage de planage inférieur 46. On se retrouve alors dans la position représentée aux figures 3 et 4. Dans cette position, les crochets 22 de l'équipage de planage 20 sont en prise avec les crochets 40 du dispositif de retournement 10 qui supportent l'intégralité de la masse de l'équipage de planage supérieur 20, cette masse pouvant valoir plusieurs dizaines de tonnes.The drive means in vertical translation of the sliders 18 are then controlled to drive the sliders 18 and thus the frame 16 upwards. The upper leveling crew 20 being engaged with the chassis 26 is also driven upwards and is separated from the lower planing unit 46. It is then in the position shown in FIGS. figures 3 and 4 . In this position, the hooks 22 of the planing equipment 20 are engaged with the hooks 40 of the turning device 10 which support the entirety of the mass of the upper planing equipment 20, this mass being worth several tens of tons.

Le vérin de transfert 54 tire ensuite la plateforme 50 vers une autre zone de l'installation de planage afin que l'équipage de planage inférieur 46 soit rectifié.The transfer cylinder 54 then pulls the platform 50 to another area of the leveling installation so that the bottom planing unit 46 is ground.

A l'étape suivante, les moyens d'entrainement en translation 38 verticale des coulisseaux 18 sont commandés pour entraîner les coulisseaux 18 et donc le châssis 16 en translation verticale vers le bas. On se retrouve dans la position représentée à la figure 5.In the next step, the vertical translation drive means 38 of the sliders 18 are controlled to drive the sliders 18 and thus the frame 16 in vertical translation downwards. We are in the position represented in figure 5 .

Puis, les moyens 19 d'entrainement en rotation du châssis autour d'un axe horizontal sont commandés. L'équipage de planage supérieur 20 pivote de 180 degrés dans le sens horaire depuis une première position dans laquelle les rouleaux 43 de l'équipage de planage supérieur 20 sont orientés vers le bas, jusqu'à une deuxième position dans laquelle les rouleaux 43 de l'équipage de planage 20 sont orientés vers le haut. Une position intermédiaire de l'équipage de planage ayant pivoté de 90 degrés est représentée à la figure 6.Then, the means 19 for rotating the chassis around a horizontal axis are controlled. The upper leveling equipment 20 rotates 180 degrees clockwise from a first position in which the rollers 43 of the upper leveling equipment 20 are oriented downward, to a second position in which the rollers 43 of the planing equipment 20 are oriented upwards. An intermediate position of the planing crew having rotated 90 degrees is represented at figure 6 .

A l'étape suivante, les moyens d'entrainement en translation verticale des coulisseaux 18 sont commandés pour entraîner les coulisseaux 18 et donc le châssis 16 en translation verticale vers le bas jusqu'à une position basse permettant à un opérateur d'avoir accès aux rouleaux de planage de l'équipage supérieur 20 ou permettant sa préhension par un engin de manutention en vue d'une évacuation vers une autre zone de l'installation.In the next step, the drive means in vertical translation of the slides 18 are controlled to drive the slides 18 and thus the frame 16 in vertical translation down to a low position allowing an operator to have access to the planing rollers of the upper crew 20 or allowing its gripping by a handling machine for evacuation to another area of the installation.
