Description

TITRE : Dispositif de compaction par vibrotassage.TITLE: Compaction device by vibrotassage.
La présente invention concerne un dispositif de compaction par vibrotassage, notamment destinée au formage de blocs anodiques moulés, et fonctionnant en mode normal sous l'effet d'une excitation vibratoire.The present invention relates to a compaction device by vibrotassage, in particular for forming molded anodic blocks, and operating in normal mode under the effect of vibratory excitation.
Il est connu des dispositifs de compaction par vibrotassage, comprenant au moins un moule porté par une table oscillante assujettie par l'intermédiaire de moyens de suspension à un châssis, ladite table étant prévue pour se mouvoir relativement au châssis suivant une direction verticale sous l'effet de moyens d'actionnement en vibration. Le châssis peut être une structure porteuse fabriquée en métal ou en béton. Parfois, les moyens de suspension sont directement reliés à la structure porteuse ou au sol.It is known compaction device by vibrotassage, comprising at least one mold carried by an oscillating table secured by means of suspension means to a frame, said table being provided to move relative to the frame in a vertical direction under the effect of vibration actuating means. The frame may be a load-bearing structure made of metal or concrete. Sometimes, the suspension means are directly connected to the supporting structure or the ground.
Aujourd'hui, les dernières versions de machines de vibrotassage sont montées sur une suspension élastique, formée de coussins pneumatiques gonflables, destinés à isoler les transmissions vibratoires au sol et à l'entourage de la machine.Today, the latest versions of vibrotassage machines are mounted on an elastic suspension, formed of inflatable pneumatic cushions, intended to isolate vibratory transmissions on the ground and around the machine.
Selon la structure de la machine et ses conditions d'opérations, il peut survenir que les fréquences de vibration verticales s'approchent des fréquences propres en rotation de l'un des sous-ensembles de la machine et génèrent des mouvements aléatoires et incontrôlés de grande amplitude.Depending on the structure of the machine and its operating conditions, it may occur that the vertical vibration frequencies approach the rotational eigenfrequencies of one of the subsets of the machine and generate random and uncontrolled movements of great magnitude. amplitude.
Au voisinage des fréquences critiques, la faible raideur de la suspension peut initier un mouvement de tangage ou de roulis susceptible de dégrader les performances de compactage s'il n'est pas maîtrisé et de provoquer des dommages mécaniques importants sur les sous-ensembles anormalement sollicités. Les mouvements de roulis et de tangage peuvent parfois se combiner et résulter en un mouvement de balourd tournant autour d'un axe vertical, similaire au mouvement d'une toupie.In the vicinity of the critical frequencies, the low stiffness of the suspension can initiate a pitching or rolling movement likely to degrade compaction performance if it is not controlled and cause significant mechanical damage to the abnormally stressed sub-assemblies. . Roll and pitch movements can sometimes combine and result in unbalanced movement around a vertical axis, similar to the movement of a spinning top.
Bien entendu, plus le niveau énergétique de l'excitation motrice est élevé, plus les amplitudes des mouvements rotationnels augmentent et sont de nature à nuire à l'intégrité mécanique de la machine.Of course, the higher the energy level of the motor excitation, the greater the amplitude of the rotational movements increase and are likely to affect the mechanical integrity of the machine.
L'exploitation de la machine dans des conditions durables doit alors être limitée à des plages de fonctionnement stables purement verticales, à niveau énergétique réduit et en s'éloignant des zones de fréquences propres critiques. Ces plages de fonctionnement peuvent s'avérer très étroites et parfois difficiles à déterminer.Operation of the machine under sustainable conditions must then be limited to purely vertical stable operating ranges, reduced energy level and away from critical clean frequency areas. These operating ranges can be very narrow and sometimes difficult to determine.
La présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de compaction par vibrotassage conçu pour limiter, voire annihiler les mouvements de tangage et/ou de roulis.The object of the present invention is to remedy these drawbacks by proposing a vibrotassage compaction device designed to limit or even annihilate pitching and / or rolling movements.
Un autre but de l'invention est de proposer un dispositif de compaction dont les caractéristiques dynamiques sont pas ou peu modifiées par rapport aux dispositions préexistantes, c'est-à-dire sans modification significative des masses et inerties caractéristiques de ces machines et sans interférence avec l'excitation motrice.Another object of the invention is to propose a compaction device whose dynamic characteristics are not or little modified with respect to pre-existing arrangements, that is to say without significant modification of the masses and inertias characteristic of these machines and without interference. with motor excitation.
Un autre but de l'invention est de proposer une amélioration des dispositifs de compaction ne nécessitant pas une remise en cause fondamentale de leur conception d'origine.Another object of the invention is to propose an improvement of the compaction devices that do not require a fundamental reconsideration of their original design.
De même, un des buts de la présente invention est de permettre d'améliorer le fonctionnement des dispositifs de compaction existants en leur adaptant les moyens spécifiques de la présente invention.Similarly, one of the aims of the present invention is to make it possible to improve the operation of existing compaction devices by adapting them to the specific means of the present invention.
Un autre but de l'invention est de proposer un dispositif de compaction permettant d'élargir les plages de fonctionnement stables de la machine tant en terme de fréquence, d'excitation que de niveau énergétique.Another object of the invention is to provide a compaction device for expanding the stable operating ranges of the machine both in terms of frequency, excitation and energy level.
D'autres buts et avantages de la présente invention apparaîtront au cours de la description suivante qui n'est donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will become apparent from the following description which is given for information only and which is not intended to limit it.
L'invention concerne un dispositif de compaction par vibrotassage, notamment destiné pour le formage de blocs anodiques moulés, comprenant au moins un moule porté par une table oscillante assujettie par l'intermédiaire de moyens de suspension à un châssis, ladite table étant prévue pour se mouvoir relativement au châssis suivant une direction verticale sous l'effet de moyens d'actionnement en vibration, caractérisé en ce que le dispositif présente des moyens stabilisateurs pour limiter, voire annihiler, le tangage et/ou roulis de la table oscillante, comportant au moins une barre de torsion disposée entre la table oscillante et son châssis.The invention relates to a device for compaction by vibrotassage, in particular intended for forming molded anode blocks, comprising at least one mold carried by an oscillating table secured by means of suspension means to a frame, said table being provided for moving relative to the frame in a vertical direction under the effect of vibration actuating means, characterized in that the device has stabilizing means for limiting or even annihilating the pitch and / or roll of the oscillating table, comprising at least one torsion bar disposed between the oscillating table and its frame.
L'invention sera mieux comprise à la lecture de la description suivante, accompagnée de l'unique planche de dessin dans laquelle la figure 1 est une vue en perspective schématique d'un dispositif de compaction par vibrotassage conforme à l'invention.The invention will be better understood on reading the following description, accompanied by the single drawing board in which Figure 1 is a schematic perspective view of a vibrocompaction compaction device according to the invention.
L'invention concerne un dispositif de compaction par vibrotassage, notamment destiné pour le formage de blocs anodiques moulés.The invention relates to a compaction device by vibrocompaction, in particular for forming molded anode blocks.
Le dispositif comporte au moins un moule 2 porté, directement ou indirectement, par une table oscillante 3. Le moule peut être prévu monobloc avec la table oscillante ou peut encore être prévu amovible reposant simplement sur cette dernière.The device comprises at least one mold 2 carried, directly or indirectly, by an oscillating table 3. The mold may be provided in one piece with the oscillating table or may be removable provided simply resting on the latter.
La table oscillante 3 est assujettie par l'intermédiaire des moyens de suspension 4 à un châssis 5 et est prévue pour se mouvoir suivant une direction verticale sous l'effet de moyens d'actionnement en vibration.The oscillating table 3 is secured by means of the suspension means 4 to a frame 5 and is provided to move in a vertical direction under the effect of vibration actuating means.
On comprendra le mot « châssis » au sens large. Le châssis peut désigner une structure porteuse fabriquée en métal ou en béton, ou encore le sol.We understand the word "chassis" in the broad sense. The frame may designate a load-bearing structure made of metal or concrete, or the floor.
Les moyens de suspension sont des amortisseurs élastiques, pouvant notamment prendre la forme de moyens pneumatiques, tels que notamment des coussins gonflables, ou encore être simplement constitués par des ressorts hélicoïdaux.The suspension means are elastic dampers, which can in particular take the form of pneumatic means, such as in particular air bags, or simply be constituted by helical springs.
Les moyens d'actionnement en vibration peuvent être constitués par des dispositifs à balourds (non illustrés). Les dispositifs à balourds sont de façon traditionnelle assujettis à la table oscillante et constitués par deux systèmes à arbre à balourds en rotation inverse synchrone.The vibration actuation means may be constituted by unbalanced devices (not shown). The unbalance devices are traditionally subject to the oscillating table and consist of two synchronous inverse rotation unbalance shaft systems.
Selon l'invention, le dispositif présente des moyens stabilisateurs pour limiter, voire annihiler, le tangage et/ou roulis de la table oscillante 3 comportant au moins une barre de torsion 6, disposée entre la table oscillante 3 et son châssis 5. La table oscillante 3 illustrée présente une forme rectangulaire avec un grand et un petit côté.According to the invention, the device has stabilizing means for limiting or even annihilating the pitch and / or roll of the oscillating table 3 comprising at least one torsion bar 6, arranged between the oscillating table 3 and its frame 5. The oscillating table 3 shown has a rectangular shape with a large and a small side.
Par convention, non restrictive, on entendra par mouvement de roulis, un bercement, c'est-à-dire mouvement de rotation de la table oscillante autour de son axe longitudinal repéré Ai1 selon ledit grand côté et globalement parallèle à ce dernier.By convention, not restrictive, will be understood by rolling movement, rocking, that is to say, rotational movement of the oscillating table about its longitudinal axis marked Ai 1 along said large side and generally parallel to the latter.
De façon similaire, on entendra par mouvement de tangage un mouvement de rotation de la table oscillante 3 autour de son axe transversal repéré A 2, selon ledit petit côté et globalement parallèle à ce dernier.In a similar manner, pitch movement will be understood to mean a rotational movement of the oscillating table 3 about its transverse axis marked A 2 along said small side and generally parallel to the latter.
Selon un mode de réalisation avantageux, ledit dispositif de stabilisation comporte au moins une barre de torsion 6 disposée suivant un axe horizontal perpendiculaire à l'axe de tangage (A2) et/ou de roulis (A-i) à inhiber.According to an advantageous embodiment, said stabilization device comprises at least one torsion bar 6 disposed along a horizontal axis perpendicular to the axis of pitch (A 2 ) and / or roll (Ai) to be inhibited.
A cette fin, telle qu'illustrée, une barre de torsion 6 est disposée sensiblement parallèle audit petit côté de la table oscillante 3 afin de limiter, voire annihiler, le mouvement de roulis de la table 3. De même, une barre de torsion 6 est disposée sensiblement parallèle au grand côté de la table oscillante 3 afin de limiter, voire annihiler, le mouvement de tangage de la table.For this purpose, as illustrated, a torsion bar 6 is disposed substantially parallel to said small side of the oscillating table 3 in order to limit or even annihilate the rolling motion of the table 3. Likewise, a torsion bar 6 is arranged substantially parallel to the long side of the oscillating table 3 in order to limit or even annihilate the pitching movement of the table.
Les moyens stabilisateurs comprennent, en outre, des moyens pour imposer à ladite barre de torsion 6, un moment d'action et un moment de réaction lors d'une prise de roulis et/ou tangage de la table 3 afin de rétablir l'horizontalité du plan de la table oscillante.The stabilizing means furthermore comprise means for imposing on said torsion bar 6 a moment of action and a moment of reaction when rolling and / or pitching the table 3 in order to restore the horizontality. from the plane of the oscillating table.
Selon un mode de réalisation, les moyens pour imposer, à ladite barre de torsion 6, un moment d'action et un moment de réaction sont constitués par deux bras articulés 8, 9, aptes à traduire un écart différentiel de niveau de table 3, entre deux points distants, en ledit moment de torsion d'action et ledit moment de torsion de réaction imposés à ladite barre.According to one embodiment, the means for imposing, on said torsion bar 6, a moment of action and a moment of reaction are constituted by two articulated arms 8, 9, able to translate a differential difference of level of table 3, between two distant points, at said twisting moment of action and said twisting moment of reaction imposed on said bar.
La barre de torsion 6 se comporte comme un moyen de rappel asservissant les deux bras articulés 8, 9. Tant que les bras sont en phase, la barre de torsion n'est pas sollicitée, les bras étant liés à la table en deux points distants. Dès l'initiation d'une prise de roulis et/ou de tangage, les deux bras ne sont plus en phase, imposant ainsi des moments d'actions et de réaction à ladite barre 6. L'élasticité de la barre de torsion force alors les bras à être de nouveau en phase rétablissant ainsi l'horizontalité du plan de la table oscillante.The torsion bar 6 behaves as a return means controlling the two articulated arms 8, 9. As long as the arms are in phase, the torsion bar is not stressed, the arms being connected to the two-point table apart. At the initiation of a roll and / or pitching, the two arms are no longer in phase, thus imposing moments of action and reaction to said bar 6. The elasticity of the torsion bar then forces the arms to be in phase again restoring the horizontality of the plane of the oscillating table.
Telle qu'illustrée, la barre de torsion 6 est articulée à la table oscillante 3 en rotation par l'intermédiaire de paliers 10. Selon ce mode de réalisation, chaque bras articulé 8, 9 est constitué par une tige de contrainte 7 faisant saillie à partir de la barre de torsion 6, ladite tige de contrainte 7 étant articulée au châssis 5 par l'intermédiaire d'au moins une biellette 11.As illustrated, the torsion bar 6 is articulated to the oscillating table 3 in rotation through bearings 10. According to this embodiment, each articulated arm 8, 9 is constituted by a stress rod 7 protruding from from the torsion bar 6, said stress rod 7 being articulated to the frame 5 via at least one rod 11.
L'extrémité distale de la tige de contrainte 7 est articulée au châssis par l'intermédiaire d'une biellette 11. Les extrémités de chaque biellette 11 présentent une articulation 12 d'axe de rotation parallèle à l'axe longitudinal de la barre de torsion 6.The distal end of the stress rod 7 is articulated to the frame by means of a link 11. The ends of each link 11 have a hinge 12 of axis of rotation parallel to the longitudinal axis of the torsion bar 6.
Selon un autre mode de réalisation non illustré, le montage des deux bras articulés et de la barre de torsion peut être inversé. Notamment, la barre de torsion peut être articulée au châssis, en rotation par l'intermédiaire de paliers. Selon ce mode de réalisation, chaque bras articulé est constitué par une tige de contrainte faisant saillie de la barre de torsion. Ladite tige de contrainte est articulée à la table oscillante par l'intermédiaire d'au moins une biellette.According to another embodiment not illustrated, the mounting of the two articulated arms and the torsion bar can be reversed. In particular, the torsion bar can be articulated to the frame, rotating through bearings. According to this embodiment, each articulated arm is constituted by a stress rod projecting from the torsion bar. Said stress rod is articulated to the oscillating table by means of at least one rod.
De la même façon, les axes de rotation des articulations des biellettes sont parallèles à l'axe longitudinal de la barre de torsion.In the same way, the axes of rotation of the joints of the rods are parallel to the longitudinal axis of the torsion bar.
Ce dernier mode de réalisation présentera l'avantage supplémentaire de minimiser l'impact des masses additionnelles des barres sur l'équilibre dynamique du dispositif.This latter embodiment will have the additional advantage of minimizing the impact of the additional masses of the bars on the dynamic equilibrium of the device.
Selon un mode avantageux de réalisation, le dispositif présentera deux ou quatre barres de torsion, disposées perpendiculaires entre elles.According to an advantageous embodiment, the device will have two or four torsion bars, arranged perpendicular to each other.
Le dispositif trouve une application particulière, mais non limitative, pour la fabrication de blocs anodiques moulés. En effet, l'invention pourra trouver son application dans tout type de machine de compaction de produits divers demandant à être vibres pour améliorer leur densité.The device finds a particular application, but not limiting, for the manufacture of molded anode blocks. Indeed, the invention can find its application in any type of compaction machine of various products requiring to be vibrated to improve their density.
Naturellement, d'autres modes de mise en œuvre à la portée de l'homme de l'Art, auraient pu être envisagés sans pour autant sortir du cadre de l'invention. Naturally, other modes of implementation within the reach of the man of the art, could have been envisaged without departing from the scope of the invention.
