Definitions
- the present invention relates to a device and method for flattening metal product strip or plate type respectively preambles of claims 1 and 9.
- hot and cold rolling plants including planing or pre-planing, for example of the "Steckel mill” type (hot-reversing mill) or “Plate Mill” (sheet metal rolling mill), or even a section of roughing a hot strip mill type of installation
- products plates or strips whose criteria of thickness, flatness, hardening or other mechanical properties are very variable are more or less hovering, if at all.
- planing is not to be done, a first method would be to lift the upper cassette to leave pass the product without leveling and use the lower cassette as a simple roller table to support the product as it passes. Therefore, the leveling rollers of the lower cassette are not very suitable for the simple function of rolling product support and very expensive. It must therefore be avoided that they suffer harmful damage to the good quality of planing.
- the simple running speed of the product on the lower cassette would generally be and much higher than the planing speed of a product (for example five times higher) and this difference in speeds would also cause overheating or overheating. blows and therefore marks of the product on the planing rollers, implying an obvious degradation of the surface condition of said rollers, and therefore detrimental to the quality of the planed product, forcing premature and therefore expensive changes in said rolls.
- An object of the present invention is to provide a metal product leveling installation temporarily to inhibit - and for example to replace by at least one product support rolling - a feature or a planing step for at least one product of a sequence of products in scrolling, without damaging the planing installation and reversibly to restore a functionality or planing step for another subsequent product. It is also envisaged to go from a planing functionality to an inhibited leveling functionality (for example rolling support) or vice versa for the same product during a series of passes of the same product in said installation.
- planing inhibition and a feature replacement for example by at least one product support by rolling
- This duration is estimated at most at a time interval between the tail start time of a first product at the exit of the leveling plant (under active leveling mode) and the arrival time of the head of a second product subsequent to the entry of the installation (in inhibited planing mode).
- Another aim is finally, instead of the leveling step, to be able to introduce at least one other functional step associated with the metallurgical process of the line, different from the step of simply supporting the product by rolling given here as an example.
- a set of subclaims also has advantages of the invention.
- Figure 1 presents a first general view of the leveling installation according to the invention, upstream side with respect to the direction or axis D of scrolling of a metal product (PM) of active planing mode.
- the scrolling can also be reversible, which is formalized by the two-way arrow, referenced by the axis (D).
- the same leveling installation can be considered with an upstream side of the scrolling situated on the opposite side compared to the representation of the figure 1 .
- the step of passing an active mode of the leveling installation to switch the leveling installation to an inhibited leveling mode is also carried out so as to allow a mode of operation related to the replacement tool (here an OR roller table used to support the product by rolling).
- the solidarized unit in active leveling mode is advantageously kept in solidarized form until the inhibited leveling mode (and vice versa), that is to say that it is free of any decoupling of the drive means and of their respective cassettes, as well as any decoupling of any other means necessary for the operation of the leveling installation and its components such as signal connections and / or supply of energy and distributed fluids or gases of said components.
- the lower and upper drive means (motors, gearboxes, extensions, connectors, etc.) and the leveling rollers of the upper and lower cassettes remain coupled together, and the other connection means (connections of signals or / and power) necessary for the operation of the leveling installation also remain connected together during the passage of a mode active to an inhibited mode and vice versa.
- This allows a considerable time saving compared to a solution requiring decoupling or other spacing of cassettes from its drive means and connections to replace at least the lower cassette by the replacement tool.
- the replacement tool may advantageously comprise a large variety of tools (alone or in combination) such as: a roller table or measuring means or an inspection means or a cutting means, or a maintenance means, or cleaning means, or pickling means, or surface treatment means.
- a horizontal roller table conveying the product along the axis of scrolling as a tool replacement (OR) in the operator-side standby position.
- the said roller table is advantageously equipped with intrinsic means for rotating its rollers, which makes it possible to increase at will the speed of passage of a subsequent product (non-planar, in inhibited mode of planing), and therefore to prevent any damage to the leveling rollers of the lower cassette if the product had to pass over it.
- the moving means may simply comprise a carriage (such as a rolling or sliding structure) commonly coupled to the lower drive means and to the lower cassette, said carriage coupling making it possible to advantageously maintain the set of lower feed means. training connected to the lower cassette during the transition from the active leveling mode to the inhibited leveling mode and vice versa.
- a carriage such as a rolling or sliding structure
- the replacement tool (such as the roller table shown) is routed and disposed on the operator side (CO) facing the frame B by means of a known multi-position lateral positioning system (Pos) such that that sometimes already exists advantageously to perform a removal cassettes for quick exchange with another operating set of cassettes.
- the replacement tool is then simply stowed to the lower cassette in order to be able to follow the same movements (transverse to the scroll axis D) as said cassette when activating said movements forward / back governed by the means of displacements (MD).
- Figure 2 presents a second view of the leveling installation according to the invention (as figure 1 ), upstream side, in active leveling mode.
- the lower and upper entrainment means (Me1, Me2) previously described in figure 1 comprise at least one motor (M1, M2), optional reducing modules (R1, R2) and elongations (A1, A2) respectively connected to the lower and upper cassette leveling rollers by means of connectors (Co1, Co2).
- These connectors are generally integral with the extensions, such as sleeves, but are here specified to describe the invention more clearly.
- An extraction means (VI) of the two lower and upper cassettes towards the operator side (CO) is embedded on the carriage (MD), so that the two cassettes can be extracted from the frame (B) for example for a conventional operation of maintenance.
- This extraction means coupled to the lower cassette remains simply in the retracted position when changing from the active mode of planing to the inhibited leveling mode, said retracted position favoring a protection of the internal piston rod against external pollution during the two active modes and inhibited planing.
- the planing rollers of the lower cassette ( C1) can very advantageously remain housed in the connectors (Co1) of the extensions (A1), the said extensions remaining integral with at least one optional reduction module (R1) connected to at least the motor (M1), thus avoiding disassembly of these elements, then especially avoiding finally a long reassembly for the return to the active mode of planing.
- the optional reducer module (R1) shown is given by way of example, and could be eliminated or replaced by a reduction, multiplier or simple gearbox form.
- the carriage as a simple and fast moving means embeds the secured assembly comprising the lower cassette (C1) , the extensions (A1) and their connectors (Co1), the optional gearbox (R1) and the motor (M1). Since the planing roller drive extensions are thus never decoupled from said rollers, the duration of the change of the lower cassette by the replacement tool is therefore mainly dependent only on the speed of the moving means (MD). Depending on the dynamic performance of the moving means (MD), it is therefore technologically possible to reduce the duration of the change cycle according to the required requirements such as the distance and speed between a tail of a product and a head of a subsequent product.
- the upper training means (Me2) of the figure 1 is detailed in figure 2 and includes connectors (Co2) to rolls of the upper cassette (C2), said connectors being connected to the extensions (A2), themselves driven by at least one optional module (R2) linked to at least one motor (M2).
- the optional reducer module (R2) shown is given by way of example, and could be eliminated or replaced by a reduction, multiplier or simple gearbox form.
- Said upper drive means (Me2) is sufficiently raised relative to the lower drive means (Me1), for example placing it on or above a bridge (P) fixed to the ground (S), so that the lower drive means (Me1) passes under said bridge during a change of the lower cassette (C1) by the replacement tool (OR) and vice versa.
- this means of motorization coupled to the lower cassette simply remains in the retracted position during an active planing mode, said retracted position favoring a protection of the inner rod of the cylinder against external pollution during planing.
- Figure 4 has a fourth view upstream side of the leveling installation according to the invention such that Figures 1 to 3 , in inhibited leveling mode, that is, once the lower cassette (C1) has been moved to the motor side (CM).
- the replacement tool (OR) such as the roller table shown in this example was then also driven by the lower cassette to take its place.
- Figure 5 finally presents a fifth view of the leveling installation according to the invention according to one of the Figures 1 to 4 , in inhibited planing mode as in figure 4 but downstream side.
- the lower and upper training means (Me1, Me2) according to figure 1 and their means of supply (CON) according to figure 4 are more explicitly represented or detailed.
- the solidarized assembly grouping in series the motor (M1), the optional reducer module (R1), the extensions (A1) and their connectors (Co1), the lower cassette (C1) to which is stowed (by AR coupling ) the replacement tool (OR) are all coupled to the flexible connection means (CON) along a stroke of the moving means (MD) defined by its positioning between the two modes of active and inhibited planarization.
- figure 6 has a sixth upstream side view of the leveling installation according to the invention, in Inhibited planing, comprising a single motor (M3) and an extension (A3) connecting the motor (M3) to the optional reduction modules (R1, R2).
- M3 single motor
- A3 extension
- R1, R2 optional reduction modules
- Figure 6 thus has a first secured assembly comprising the lower cassette (C1) and the lower drive means, said lower drive means comprising the single motor (M3), an extension (A3) connecting the motor to an optional module of reduction (R1), said optional module being coupled to the extension (A1) connected to the leveling roller of the lower cassette (C1).
- the extension (A3) drives the two optional lower and upper reduction modules (R1, R2).
- the lower reduction module (R1) is however free axially on the extension (A3), the extension (A3) being fixed relative to the ground (S).
- the upper reduction module (R2) is fixed relative to the ground (S) (for example on a bridge P).
- Figure 7 presents a seventh upstream side view of a planing installation alternative according to the figure 6 , in inhibited planing mode, comprising the single motor (M3).
- the motor (M3) and its extension (A3) are embedded on the moving means (MD).
- the extension (A3) drives the two optional lower and upper reduction modules (R1, R2).
- the lower reduction module (R1) is movable with the extension (A3) relative to the ground (S), these two elements being movable on the moving means (MD).
- the upper reduction module (R2) is fixed relative to the ground (S) (for example on a bridge P), but the elongate (A3) is axially free with respect to said reduction module (R2).
- the method according to the invention can also provide that a first product undergoes the first pass and a second product distinct from the first undergoes the second pass.
- the functional step of said method according to the invention can thus in a very varied manner be at least one of the following steps: a support step by product rolling or a measurement step or an inspection step or a cutting step , or a maintenance step, or a cleaning step, or a pickling step or a surface treatment step.
- the complete replacement step is performed under a time less than a time interval between the product start time outside the leveling installation and the product arrival time in the installation. This is the case for a single product undergoing both first and second passes above.
- the method according to the invention provides for a more that the complete replacement step is performed within a period of less than a time interval between the tail start time of the first product at the exit of the leveling plant and the arrival time of the second product. at the entrance to the facility.
- the time interval is, as an indication, less than a few minutes, and ideally less than one minute.
- the duration times indicated above can be of the same order in the case of treatment of two different products or the same product passing successively in the installation active or inhibited planing mode and vice versa.
- the method according to the invention provides that the replacement step is reversible in order to return the lower cassette in the frame, instead of the replacement tool. It is therefore possible to switch from an active leveling pass to an inhibited leveling pass (and activated tool) and vice versa for any sequence of passes.
- the successive reversible stages are identically always fast, because they are free of any decoupling of the integral whole and related connections.
- the method according to the invention can provide that a small vertical spacing of the upper and lower cassettes is established at the start of the activation at the beginning of replacement of the lower cassette by replacement tool.

Description
La présente invention concerne une dispositif et une méthode de planage de produit métallique de type bande ou plaque selon respectivement les préambules des revendications 1 et 9.The present invention relates to a device and method for flattening metal product strip or plate type respectively preambles of claims 1 and 9.
A l'heure actuelle, des installations de planage de produit métallique en défilement de type bande ou plaque sont connues et comprennent généralement:
- un bâti dans lequel sont disposées une cassette inférieure de planage et une cassette supérieure de planage,
- un moyen inférieur d'entrainement en rotation de rouleaux de planage de la cassette inférieure,
- un moyen supérieur d'entrainement en rotation de rouleaux de planage de la cassette supérieure,
- les moyens supérieur et inférieur d'entrainement étant disposés sur un premier coté dit « moteur » et extérieur au bâti, latéralement par rapport à un axe de défilement du produit.
- a frame in which are disposed a lower leveling cassette and an upper leveling cassette,
- a lower means of driving in rotation of planing rollers of the lower cassette,
- an upper means for rotating the planing rolls of the upper cassette,
- the upper and lower drive means being disposed on a first side called "motor" and outside the frame, laterally with respect to a scroll axis of the product.
En particulier sur des installations de laminage à froid comme à chaud incluant un planage ou un pré-planage, par exemple de type « Steckel mill » (laminoir réversible à chaud) ou « Plate Mill » (laminoir tôles fortes), voire une section de dégrossissage d'une installation de type « Hot Strip Mill » (laminoir train à bande à chaud), il est souhaité que des produits plaques ou bandes dont les critères d'épaisseur, de planéité, d'écrouissage ou autres propriété mécaniques sont très variables soient plus ou moins planés, voire aucunement.In particular on hot and cold rolling plants including planing or pre-planing, for example of the "Steckel mill" type (hot-reversing mill) or "Plate Mill" (sheet metal rolling mill), or even a section of roughing a hot strip mill type of installation, it is desired that products plates or strips whose criteria of thickness, flatness, hardening or other mechanical properties are very variable are more or less hovering, if at all.
Si un planage ne doit pas être effectué, une première méthode consisterait à relever la cassette supérieure pour laisser passer le produit sans planage et utiliser la cassette inférieure comme simple table à rouleaux pour supporter le produit à son passage. Dès lors, les rouleaux de planage de la cassette inférieures sont peu appropriés pour la simple fonction de supportage de produit par roulement et très coûteux. Il faut donc éviter qu'ils subissent des dommages nuisibles pour la bonne qualité de planage. De plus, la vitesse de roulage simple du produit sur la cassette inférieure serait généralement et largement plus haute que la vitesse de planage d'un produit (par exemple cinq fois plus haute) et cet écart de vitesses engendrerait également des échauffements ou des à-coups et donc des marques du produit sur les rouleaux de planage, impliquant une dégradation évidente de l'état de surface desdits rouleaux, et donc nuisible à la qualité du produit plané, obligeant à des changements prématurés et donc coûteux des dits rouleaux.If planing is not to be done, a first method would be to lift the upper cassette to leave pass the product without leveling and use the lower cassette as a simple roller table to support the product as it passes. Therefore, the leveling rollers of the lower cassette are not very suitable for the simple function of rolling product support and very expensive. It must therefore be avoided that they suffer harmful damage to the good quality of planing. In addition, the simple running speed of the product on the lower cassette would generally be and much higher than the planing speed of a product (for example five times higher) and this difference in speeds would also cause overheating or overheating. blows and therefore marks of the product on the planing rollers, implying an obvious degradation of the surface condition of said rollers, and therefore detrimental to the quality of the planed product, forcing premature and therefore expensive changes in said rolls.
Un but de la présente invention est de proposer une installation de planage de produit métallique permettant temporairement d'inhiber - et par exemple de remplacer par au moins un supportage de produit par roulage - une fonctionnalité ou une étape de planage pour au moins un produit d'une séquence de produits en défilement, sans endommager l'installation de planage et de façon réversible pour rétablir une fonctionnalité ou étape de planage pour un autre produit subséquent. Il est également envisagé de passer d'une fonctionnalité de planage à une fonctionnalité inhibée de planage (par exemple de supportage par roulage) ou vice versa pour un même produit au cours d'une série de passages de ce même produit dans la dite installation.An object of the present invention is to provide a metal product leveling installation temporarily to inhibit - and for example to replace by at least one product support rolling - a feature or a planing step for at least one product of a sequence of products in scrolling, without damaging the planing installation and reversibly to restore a functionality or planing step for another subsequent product. It is also envisaged to go from a planing functionality to an inhibited leveling functionality (for example rolling support) or vice versa for the same product during a series of passes of the same product in said installation.
Il est aussi ainsi requis de réaliser une telle inhibition de planage (et un remplacement de fonctionnalité par exemple par au moins un supportage de produit par roulage) sous une durée assez courte pour ne pas ralentir le flux d'arrivée des produits sur l'installation de planage, c'est-à-dire sans diminuer la productivité de l'installation globale d'une ligne utilisant la dite installation de planage. Cette durée est estimée au maximum à un intervalle de temps compris entre le temps de départ de queue d'un premier produit à la sortie de l'installation de planage (sous mode de planage actif) et le temps d'arrivée de tête d'un second produit subséquent à l'entrée de l'installation (sous mode de planage inhibé).It is also thus required to perform such planing inhibition (and a feature replacement for example by at least one product support by rolling) in a relatively short time to not slow down the flow of products arrival. on the leveling installation, that is to say without decreasing the productivity of the overall installation of a line using the said leveling installation. This duration is estimated at most at a time interval between the tail start time of a first product at the exit of the leveling plant (under active leveling mode) and the arrival time of the head of a second product subsequent to the entry of the installation (in inhibited planing mode).
Un autre but est enfin, en lieu et place de l'étape de planage, de pouvoir introduire au moins une toute autre étape fonctionnelle associée au procédé métallurgique de la ligne, différente de l'étape d'un simple supportage du produit par roulage donné ici à titre d'exemple.Another aim is finally, instead of the leveling step, to be able to introduce at least one other functional step associated with the metallurgical process of the line, different from the step of simply supporting the product by rolling given here as an example.
A ce titre, une installation de planage et une méthode mise en oeuvre par ladite installation sont ainsi proposées au travers des caractéristiques des revendications 1 et 9.As such, a leveling installation and a method implemented by said installation are thus proposed through the features of claims 1 and 9.
Un ensemble de sous-revendications présente également des avantages de.l'invention.A set of subclaims also has advantages of the invention.

- the secured assembly comprising a replacement tool (OR) of the lower cassette, said tool being coupled to the lower cassette of a second operator side (CO) opposite the first motor side with respect to the axis (D) of scrolling of the product.
Ainsi, l'étape de passage d'un mode actif de l'installation de planage pour commuter l'installation de planage sur un mode inhibé de planage est réalisée afin également de permettre un mode de fonctionnent lié à l'outil de remplacement (ici une table à rouleaux OR utilisée pour supportage du produit par roulage). L'ensemble solidarisé en mode actif de planage est avantageusement conservé sous forme solidarisée jusqu'au mode inhibé de planage (et vice-versa), c'est-à-dire qu'il est libre de tout découplage des moyens d'entrainement et de leurs cassettes respectives, ainsi que de tout découplage de tout autre moyen nécessaire au fonctionnement de l'installation de planage et ses composantes tels que des connexions de signaux ou/et d'alimentation en énergie et fluides ou gaz distribués des dites composantes. En d'autres termes, les moyens inférieurs et supérieurs d'entrainement (motorisations, réducteurs, allonges, connecteurs, etc.) et les rouleaux de planage des cassettes inférieures et supérieures restent accouplées entre eux, et les autres moyens de connexions (connexions de signaux ou/et d'alimentation) nécessaires au fonctionnement de l'installation de planage restent aussi solidairement connectés lors du passage d'un mode actif vers un mode inhibé et vice-versa. Ceci permet un gain considérable de temps par rapport à une solution nécessitant un découplage ou tout autre écartement de cassettes de ses moyens d'entrainement ainsi que des connexions afin de remplacer au moins la cassette inférieure par l'outil de remplacement.Thus, the step of passing an active mode of the leveling installation to switch the leveling installation to an inhibited leveling mode is also carried out so as to allow a mode of operation related to the replacement tool (here an OR roller table used to support the product by rolling). The solidarized unit in active leveling mode is advantageously kept in solidarized form until the inhibited leveling mode (and vice versa), that is to say that it is free of any decoupling of the drive means and of their respective cassettes, as well as any decoupling of any other means necessary for the operation of the leveling installation and its components such as signal connections and / or supply of energy and distributed fluids or gases of said components. In other words, the lower and upper drive means (motors, gearboxes, extensions, connectors, etc.) and the leveling rollers of the upper and lower cassettes remain coupled together, and the other connection means (connections of signals or / and power) necessary for the operation of the leveling installation also remain connected together during the passage of a mode active to an inhibited mode and vice versa. This allows a considerable time saving compared to a solution requiring decoupling or other spacing of cassettes from its drive means and connections to replace at least the lower cassette by the replacement tool.
L'outil de remplacement peut avantageusement comprendre une forte diversité d'outils (seul ou combinés) tels que : une table à rouleaux ou un moyen de mesure ou un moyen d'inspection ou un moyen de découpe, ou un moyen de maintenance, ou un moyen de nettoyage, ou un moyen de décapage, ou un moyen de traitement de surface.The replacement tool may advantageously comprise a large variety of tools (alone or in combination) such as: a roller table or measuring means or an inspection means or a cutting means, or a maintenance means, or cleaning means, or pickling means, or surface treatment means.
Dans l'exemple donné pour illustrer un mode de réalisation de l'installation selon l'invention, il est représenté en position d'attente côté opérateur une table à rouleaux horizontaux de convoyage du produit selon l'axe de défilement en tant qu'outil de remplacement (OR) en position d'attente côté opérateur. La dite table à rouleaux est avantageusement équipée de moyens intrinsèques d'entrainement en rotation de ses rouleaux, ce qui permet de pouvoir augmenter à volonté la vitesse de passage d'un produit subséquent (non plané, sous mode inhibé de planage), et donc de préserver tout endommagement des rouleaux de planage de la cassette inférieure si le produit avait dû transiter dessus.In the example given to illustrate an embodiment of the installation according to the invention, it is shown in the waiting position on the operator side a horizontal roller table conveying the product along the axis of scrolling as a tool replacement (OR) in the operator-side standby position. The said roller table is advantageously equipped with intrinsic means for rotating its rollers, which makes it possible to increase at will the speed of passage of a subsequent product (non-planar, in inhibited mode of planing), and therefore to prevent any damage to the leveling rollers of the lower cassette if the product had to pass over it.
Le moyen de déplacement (MD) peut simplement comprendre un chariot (comme une structure roulante ou coulissante) couplée communément aux moyens inférieurs d'entrainement et à la cassette inférieure, le dit couplage de chariot permettant de maintenir avantageusement l'ensemble des moyens inférieurs d'entrainement solidarisés à la cassette inférieure lors du passage du mode de planage actif au mode de planage inhibé et vice-versa.The moving means (MD) may simply comprise a carriage (such as a rolling or sliding structure) commonly coupled to the lower drive means and to the lower cassette, said carriage coupling making it possible to advantageously maintain the set of lower feed means. training connected to the lower cassette during the transition from the active leveling mode to the inhibited leveling mode and vice versa.
L'outil de remplacement (OR) (telle que la table à rouleaux représentée) est acheminé et disposé sur le côté opérateur (CO) en face du bâti B au moyen d'un système connu de positionnement latéral à positions multiples (Pos) tel que celui qui existe parfois déjà avantageusement pour effectuer un retrait des cassettes pour échange rapide avec un autre jeu opérationnel de cassettes. L'outil de remplacement est alors simplement arrimé à la cassette inférieure afin de pouvoir suivre les mêmes mouvements (transversaux à l'axe de défilement D) que la dite cassette lors de l'activation des dits mouvements avant/arrière régis par les moyens de déplacements (MD).The replacement tool (OR) (such as the roller table shown) is routed and disposed on the operator side (CO) facing the frame B by means of a known multi-position lateral positioning system (Pos) such that that sometimes already exists advantageously to perform a removal cassettes for quick exchange with another operating set of cassettes. The replacement tool is then simply stowed to the lower cassette in order to be able to follow the same movements (transverse to the scroll axis D) as said cassette when activating said movements forward / back governed by the means of displacements (MD).
Les moyens inférieurs et supérieurs d'entrainement (Me1, Me2) précédemment décrits en
Un moyen d'extraction (VI) des deux cassettes inférieure et supérieure vers le côté opérateur (CO) est embarqué sur le chariot (MD), de sorte que les deux cassettes puissent être extraites du bâti (B) par exemple pour une opération classique de maintenance. Ce moyen d'extraction couplé à la cassette inférieure reste toutefois simplement en position rétractée lors d'un changement du mode actif de planage vers le mode inhibé de planage, la dite position rétractée favorisant une protection de la tige interne de vérin contre une pollution externe pendant les deux modes actifs et inhibé de planage. De plus et en conséquence de la rétraction permanente du vérin et durant ce changement de modes régi par une translation du chariot (MD) entrainant la cassette inférieure (C1) vers le côté moteur (CM), les rouleaux de planage de la cassette inférieure (C1) peuvent fort avantageusement rester logées dans les connecteurs (Co1) des allonges (A1), les dites allonges restant solidaires à au moins un module optionnel réducteur (R1) liés à au moins au moteur (M1), évitant ainsi un démontage de ces éléments, puis surtout évitant enfin un long remontage pour le retour au mode actif de planage. Le module optionnel réducteur (R1) représenté est donné à titre d'exemple, et pourrait être éliminé ou remplacé par sous une forme de cage à pignons de type réductrice, multiplicatrice ou simple. En résumé, lors d'un changement de mode actif de planage vers un mode inhibé de planage et vice-versa, le chariot en tant que simple et rapide moyen de déplacement (MD) embarque l'ensemble solidarisé comprenant la cassette inférieure (C1), les allonges (A1) et leurs connecteurs (Co1), le module optionnel réducteur (R1) et le moteur (M1). Les allonges d'entrainement de rouleaux de planage n'étant ainsi ici jamais découplées desdits rouleaux, la durée du changement de la cassette inférieure par l'outil de remplacement est donc principalement seulement dépendante de la vitesse du moyen de déplacement (MD). En fonction des performances dynamiques du moyen de déplacement (MD), il est donc technologiquement possible de réduire la durée du cycle de changement en fonction des besoins requis telle que la distance et la vitesse entre une queue d'un produit et une tête d'un produit subséquent.An extraction means (VI) of the two lower and upper cassettes towards the operator side (CO) is embedded on the carriage (MD), so that the two cassettes can be extracted from the frame (B) for example for a conventional operation of maintenance. This extraction means coupled to the lower cassette, however, remains simply in the retracted position when changing from the active mode of planing to the inhibited leveling mode, said retracted position favoring a protection of the internal piston rod against external pollution during the two active modes and inhibited planing. In addition and as a result of the permanent retraction of the cylinder and during this change of modes governed by a translation of the carriage (MD) driving the lower cassette (C1) to the motor side (CM), the planing rollers of the lower cassette ( C1) can very advantageously remain housed in the connectors (Co1) of the extensions (A1), the said extensions remaining integral with at least one optional reduction module (R1) connected to at least the motor (M1), thus avoiding disassembly of these elements, then especially avoiding finally a long reassembly for the return to the active mode of planing. The optional reducer module (R1) shown is given by way of example, and could be eliminated or replaced by a reduction, multiplier or simple gearbox form. In summary, during a change from active planing mode to an inhibited planing mode and vice versa, the carriage as a simple and fast moving means (MD) embeds the secured assembly comprising the lower cassette (C1) , the extensions (A1) and their connectors (Co1), the optional gearbox (R1) and the motor (M1). Since the planing roller drive extensions are thus never decoupled from said rollers, the duration of the change of the lower cassette by the replacement tool is therefore mainly dependent only on the speed of the moving means (MD). Depending on the dynamic performance of the moving means (MD), it is therefore technologically possible to reduce the duration of the change cycle according to the required requirements such as the distance and speed between a tail of a product and a head of a subsequent product.
Le moyen d'entrainement supérieur (Me2) de la
Le chariot (= moyen de déplacement MD) peut enfin être mu par rapport au sol (S) ou au bâti (B) fixé au sol et/ou aux autres éléments fixes au moyen d'un unique élément moteur tel qu'un vérin (V2) - voir
L'installation selon l'invention prévoit aussi des connexions (CON) de signaux ou/et d'alimentation en énergie et fluides ou gaz distribués pour les moyens inférieurs d'entrainement (Me1), la cassette inférieure (C1) et éventuellement l'outil de remplacement (OR). Ces connexions (CON) sont simplement couplés au sol (S) ou au bâti (B) fixé au sol et/ou à d'autres éléments fixes ainsi qu'au moyen de déplacement (MD) prévoyant des connecteurs appropriés pour les dites connexions (CON). Au même titre que l'ensemble solidarisé comprenant la cassette inférieure (C1) et les moyens d'entrainement inférieurs (Me1), ces connexions (CON) restent sont donc avantageusement libres de toute déconnexion ou découplage, lors du changement de la cassette inférieure par l'outil de remplacement et vice-versa. Ici encore un gain considérable de temps est donc atteint lors dudit changement. De manière pratique selon l'exemple ici donné, les connexions (CON) comprennent des supports flexibles comme des chaines porte-câbles disposées entre le sol (S) et au moins si besoin un de chacun des diverses composants de l'ensemble solidarisé, à savoir :
- Les moyens d'entrainement inférieur (Me1) comprenant un moteur, un module réducteur couplés au moteur et les allonges inférieures;
- La cassette inférieures (C1) ;
- Optionnellement et préférentiellement, l'outil de remplacement si il requiert au moins une quelconque alimentation dont une mise en oeuvre serait possible depuis le côté moteur du bâti vers le dit outil.
- The lower drive means (Me1) comprising a motor, a gear unit coupled to the motor and the lower extensions;
- The lower cassette (C1);
- Optionally and preferably, the replacement tool if it requires at least one power supply whose implementation would be possible from the motor side of the frame towards said tool.
Les moyens inférieur et supérieur d'entrainement (Me1, Me2) selon
En particulier, l'ensemble solidarisé regroupant en série le moteur (M1), le module optionnel réducteur (R1), les allonges (A1) et leurs connecteurs (Co1), la cassette inférieure (C1) à laquelle est arrimé (par couplage AR) l'outil de remplacement (OR), sont tous couplés aux moyens flexibles de connexion (CON) sur toute une course du moyen de déplacement (MD) définie par son positionnement entre les deux modes de planage actif et inhibé.The lower and upper training means (Me1, Me2) according to
In particular, the solidarized assembly grouping in series the motor (M1), the optional reducer module (R1), the extensions (A1) and their connectors (Co1), the lower cassette (C1) to which is stowed (by AR coupling ) the replacement tool (OR), are all coupled to the flexible connection means (CON) along a stroke of the moving means (MD) defined by its positioning between the two modes of active and inhibited planarization.
Alternativement aux exemples de réalisation de l'installation selon l'invention présentés aux
A ce titre,
Dans ce cas, il est à prévoir que le moyen de déplacement (MD) d'un ensemble solidarisé comprenant la cassette inférieure (C1) et le moyen inférieur d'entrainement (M3, A3, R1, A1), le dit moyen de déplacement étant activable pour un retrait de la cassette inférieure hors du bâti (B) vers le premier côté moteur (CM) ou vice-versa pour une insertion de la cassette inférieure depuis le premier côté moteur dans le bâti,
- l'ensemble solidarisé comprenant un outil de remplacement (OR) de la cassette inférieure, le dit outil étant accouplé à la cassette inférieure d'un second côté opérateur (CO), opposé au premier côté moteur par rapport à l'axe (D) de défilement du produit.
- the secured assembly comprising a replacement tool (OR) of the lower cassette, said tool being coupled to the lower cassette of a second operator side (CO), opposite to the first motor side with respect to the axis (D) scrolling of the product.
L'allonge (A3) entraine les deux modules optionnels de réduction inférieur et supérieur (R1, R2). Le module inférieur de réduction (R1) est toutefois libre axialement sur l'allonge (A3), l'allonge (A3) étant fixe par rapport au sol (S). Le module supérieur de réduction (R2) est fixe par rapport au sol (S) (par exemple sur un pont P).
The extension (A3) drives the two optional lower and upper reduction modules (R1, R2). The lower reduction module (R1) is however free axially on the extension (A3), the extension (A3) being fixed relative to the ground (S). The upper reduction module (R2) is fixed relative to the ground (S) (for example on a bridge P).
Dans le cas de la

Il est à noter que complémentairement aux
It should be noted that, in addition to
A partir des caractéristiques des
- une première passe de produit est effectuée dans l'installation ;
- un seconde passe de produit est effectuée dans l'installation ;
- au moins une des deux passes est une passe de planage actif et l'autre passe est une passe de planage inhibé précédée d'une activation du moyen de déplacement (MD) de l'ensemble solidarisé permettant une étape de remplacement de la cassette inférieure (C1) par l'outil de remplacement (OR) afin de générer une étape fonctionnelle autre qu'une étape de planage et vice-versa si besoin.
- a first product pass is made in the installation;
- a second product pass is made in the installation;
- at least one of the two passes is an active leveling pass and the other passes is an inhibited leveling pass preceded by an activation of the displacement means (MD) of the secured assembly allowing a step of replacing the lower cassette ( C1) by the replacement tool (OR) to generate a functional step other than a planing step and vice versa if necessary.
La dite méthode selon l'invention peut prévoir qu'un même et seul produit subit les première et seconde passes, si par exemples :
- l'installation de planage doit rester ouverte et sous un mode de table à rouleaux, pour supporter sans problème de vitesse par roulage le produit alors que ce dernier est laminé par une unité de laminage située en amont ou en aval de l'installation de planage, et du fait que l'allongement du produit laminé ou son déplacement, peut s'étendre sur une plus grande distance que l'intervalle roulant entre l'unité de laminage et l'installation de planage ;
- l'installation de planage est utilisée de manière réversible ou non pour le dit produit la traversant, sachant qu'un certain nombre de passe(s) est libre de planage et au moins une passe peut exiger un planage actif.
- the leveling installation must remain open and in a roller table mode, to withstand without problem the rolling speed of the product while the latter is rolled by a rolling unit located upstream or downstream of the leveling installation and because the elongation of the rolled product or its displacement may extend a greater distance than the rolling gap between the rolling unit and the leveling plant;
- the planing installation is used reversibly or not for said product passing through it, knowing that a number of passes (s) is free of planing and at least one pass may require active planing.
Complémentairement, la méthode selon l'invention peut prévoir aussi, qu'un premier produit subit la première passe et un second produit distinct du premier subit la seconde passe.Complementarily, the method according to the invention can also provide that a first product undergoes the first pass and a second product distinct from the first undergoes the second pass.
A titre d'exemple, on peut citer un tel schéma de méthode comprenant les étapes suivantes :
- le premier produit subit une étape de planage et quitte l'installation de planage,
- le second produit à distance du premier produit est acheminé pour entrer dans l'installation de planage,
- ledit second produit nécessitant une étape fonctionnelle autre que l'étape d'un planage, une activation du moyen de déplacement (MD) de l'ensemble solidarisé est ordonnée permettant une étape de remplacement de la cassette inférieure (C1) par l'outil de remplacement (OR) dédié à assurer l'étape fonctionnelle à l'entrée du second produit dans l'installation autre que l'étape initiale de planage.
- the first product undergoes a leveling step and leaves the leveling installation,
- the second product remote from the first product is routed to enter the leveling plant,
- said second product requiring a functional step other than the step of planing, an activation of the displacement means (MD) of the set is ordered allowing a step of replacing the lower cassette (C1) by the tool of replacement (OR) dedicated to ensure the functional step at the entrance of the second product in the installation other than the initial step of planing.
L'étape fonctionnelle de la dite méthode selon l'invention peut ainsi de façon très variée être au moins une des étapes suivantes : une étape de soutien par roulage de produit ou une étape de mesure ou une étape d'inspection ou une étape de découpe, ou une étape de maintenance, ou une étape de nettoyage, ou une étape de décapage ou une étape de traitement de surface.The functional step of said method according to the invention can thus in a very varied manner be at least one of the following steps: a support step by product rolling or a measurement step or an inspection step or a cutting step , or a maintenance step, or a cleaning step, or a pickling step or a surface treatment step.
Préférentiellement, l'étape de remplacement complet est effectuée sous une durée inférieure à un intervalle de temps compris entre le temps de départ de produit hors de l'installation de planage et le temps d'arrivée de produit dans l'installation. C'est ainsi le cas pour un seul produit subissant les deux première et seconde passes susmentionnées.Preferably, the complete replacement step is performed under a time less than a time interval between the product start time outside the leveling installation and the product arrival time in the installation. This is the case for a single product undergoing both first and second passes above.
Dans le cas de premier et du second produit mentionnés ci-dessus, la méthode selon l'invention prévoit de manière plus détaillée que l'étape de remplacement complet soit effectuée sous une durée inférieure à un intervalle de temps compris entre le temps de départ de queue du premier produit à la sortie de l'installation de planage et le temps d'arrivée de tête du second produit à l'entrée de l'installation.In the case of first and second products mentioned above, the method according to the invention provides for a more that the complete replacement step is performed within a period of less than a time interval between the tail start time of the first product at the exit of the leveling plant and the arrival time of the second product. at the entrance to the facility.
Il est ainsi possible de prévoir des intervalles de temps requis en fonction des caractéristiques technologiques du système choisi pour le moyen de déplacement (MD). L'intervalle de temps est, à titre indicatif, inférieur à quelques minutes, et idéalement inférieur à une minute. Les temps de durée indiqués précédemment peuvent être de même ordre dans le cas de traitement de deux produits différents ou du même produit passant successivement dans l'installation en mode de planage actif ou inhibé et vice versa.It is thus possible to provide the required time intervals depending on the technological characteristics of the system chosen for the moving means (MD). The time interval is, as an indication, less than a few minutes, and ideally less than one minute. The duration times indicated above can be of the same order in the case of treatment of two different products or the same product passing successively in the installation active or inhibited planing mode and vice versa.
Enfin, la méthode selon l'invention prévoit que l'étape de remplacement est réversible afin de ramener la cassette inférieure dans le bâti, à la place de l'outil de remplacement. Il est donc possible de commuter d'une passe de planage actif à une passe de planage inhibé (et outil activé) et vice-versa pour n'importe quelle séquence de passes. Les étapes successives réversibles sont identiquement toujours rapides, car libre de tout découplage de l'ensemble solidaire et de connexions s'y rattachant.Finally, the method according to the invention provides that the replacement step is reversible in order to return the lower cassette in the frame, instead of the replacement tool. It is therefore possible to switch from an active leveling pass to an inhibited leveling pass (and activated tool) and vice versa for any sequence of passes. The successive reversible stages are identically always fast, because they are free of any decoupling of the integral whole and related connections.
La méthode selon l'invention peut prévoir qu'un faible écartement vertical des cassettes supérieures et inférieures soit établi au départ de l'activation au début du remplacement de la cassette inférieure par outil de remplacement. L'expérience montre que cet écartement peut être initié dans un temps peu significatif précédant la mise en activation du moyen de déplacement (MD), voire dans une séquence inscrite en temps masqué par rapport à la dite mise en activation du moyen de déplacement (MD).The method according to the invention can provide that a small vertical spacing of the upper and lower cassettes is established at the start of the activation at the beginning of replacement of the lower cassette by replacement tool. Experience shows that this spacing can be initiated in a little significant time preceding activation of the displacement means (MD), or even in a sequence inscribed in masked time with respect to said activation of the activation. moving means (MD).
L'activation du moyen de déplacement peut par ailleurs nécessiter en outre d'un dit déplacement de translation (par vérin V2 par exemple selon
