Abstract
Description
La présente invention a pour objet un dispositif automatisé de maintien d'éléments en bois sur une table de pressage en vue de leur assemblageThe subject of the present invention is a automated device for holding wooden elements on a pressing table for their assembly
Il est destiné à la fabrication de divers types d'assemblages tels qu'éléments de charpente, et en particulier de fermes préfabriquées de dimensions limitées connues sous le nom de "fermettes", et très largement utilisées en construction traditionnelle pour le soutien des toitures inclinées.It is intended for the manufacture of various types of assemblies such as structural elements, and particular of prefabricated trusses of dimensions limited known as "farmhouses", and very widely used in traditional construction for support for pitched roofs.
Les fermettes sont réalisées par l'assemblage en triangle, sur une table de pressage, de deux arbalétriers et d'un entrait renforcés par des pièces de triangulation judicieusement disposées. Les constituants de la fermette sont disposés sur la table de pressage et généralement maintenus par des butées mobiles coulissants dans des rainures du plateau métallique de la table et bloqués par vissage. Des "connecteurs" constitués de plaques métalliques à griffes sont alors enfoncés aux points de jonction à l'aide de vérins mobiles portés par un portique coulissant longitudinalement au-dessus de la table.The farms are made by assembling in a triangle, on a pressing table, two crossbowmen and entry reinforced by pieces of judiciously arranged triangulation. The components of the farmhouse are arranged on the pressing table and generally held by sliding sliding stops in grooves on the metal table top and blocked by screwing. "Connectors" made up of metal claw plates are then pressed into the junction points using mobile cylinders carried by a gantry sliding longitudinally above the table.
Le plus souvent les réglages et le calage des fermettes, ainsi que la commande du pressage par vérins se font à la main. Les bois sont positionnés sur la table et maintenus par les butées mises en place manuellement ; les connecteurs sont alors préenfoncés à l'aide d'un marteau, puis l'opérateur positionne les vérins au-dessus des connecteurs et actionne une manette permettant le pressage par descente desdits vérins. L'inconvénient est que les opérations de réglages étant manuelles, le temps nécessaire est important, entraínant des coûts de main d'oeuvre élevés, et le matériel utilisé (butées mobiles, rails) est endommagé rapidement.Most often the settings and timing of farms, as well as the control of pressing by cylinders are done by hand. The woods are positioned on the table and maintained by the stops placed manually; the connectors are then pre-pressed using a hammer, then the operator positions the cylinders above connectors and operates a joystick allowing pressing down said cylinders. The downside is as the adjustment operations are manual, the time necessary is important, resulting in labor costs work, and the equipment used (movable stops, rails) is damaged quickly.
Le brevet français N° 2 693 148 déposé par MM. DEBANNE ET PORTALIER décrit un dispositif permettant d'effectuer automatiquement la mise en position des butées de maintien dans les rainures du plateau métallique de la table grâce à une unité motorisée pilotée par un ensemble informatique contrôlant également les mouvements du portique mobile et des vérins de pressage.French Patent No. 2,693,148 filed by MM. DEBANNE ET PORTALIER describes a device allowing automatically position the retaining stops in the grooves of the plate metal table thanks to a motorized unit controlled by a computer system also controlling the movements of the mobile gantry and the jacks pressing.
Cet équipement présente l'inconvénient de nécessiter une table d'un type bien déterminé, équipée de rainures usinées dans le plateau, ce qui rend son coût de fabrication élevé. En outre, le déplacement longitudinal d'une butée doit se faire en trois temps pour aller tout d'abord à l'extrémité de la rainure transversale dans laquelle elle se trouve initialement, puis longer une rainure longitudinale située en bordure de la table, puis enfin emprunter une nouvelle rainure transversale. En cas de déréglage, les risques de détérioration des butées, des rainures ou du mandrin sont importants.This equipment has the disadvantage of require a table of a specific type, equipped with machined grooves in the tray, making its cost of high manufacturing. In addition, the longitudinal displacement a stop must be done in three stages to go all first at the end of the transverse groove in which it is initially, then follow a longitudinal groove located at the edge of the table, then finally take a new transverse groove. In case adjustment, the risks of deterioration of the stops, grooves or mandrel are important.
Le brevet N° 2 707 546, au nom de M. Christian DEBANNE, décrit un dispositif permettant d'utiliser une table de type quelconque, autorisant des déplacements sans contrainte des éléments de maintien sur toute la surface du plateau et minimisant les conséquences de défaillances éventuelles du mandrin ou du système informatique. Ce dispositif utilise, pour le maintien des pièces à assembler, des plots constitués de blocs cylindriques équipés en partie inférieure de pointes s'enfonçant dans un plateau de bois recouvrant la table de pressage, ces plots étant mis en place au moyen d'un mandrin mobile creux pourvu sur sa face interne d'ergots pouvant coulisser dans des rainures en "L" prévues à la périphérie des plots et agencées de manière à ce que ceux-ci puissent être libérés ou rendus solidaires du mandrin en faisant effectuer à ce dernier une rotation d'une fraction de tour dans un sens ou dans l'autre.Patent No. 2,707,546, in the name of Mr. Christian DEBANNE, describes a device making it possible to use a any type of table, allowing movement unconstrained holding elements over the entire plateau surface and minimizing the consequences of possible mandrel or system failures computer science. This device uses, for the maintenance of parts to be assembled, blocks made of blocks cylindrical fitted at the bottom with spikes sinking into a wooden tray covering the table pressing, these pads being put in place by means of a hollow mobile mandrel provided on its inner face with lugs can slide in "L" grooves provided in the periphery of the studs and arranged so that these can be released or made united with the mandrel by rotating the latter a fraction of a turn one way or the other.
Non seulement la combinaison des mouvements de rotation et de translation entraíne le risque de diminuer la fiabilité du système, mais le positionnement du mandrin au-dessus d'un plot demande une grande précision, qui ne peut être obtenue qu'en ralentissant fortement les mouvements horizontaux du mandrin. Surtout, le déplacement d'une série de plots pour réaliser une nouvelle configuration nécessite de nombreux mouvements de l'unité motorisée et du portique en raison du fait que chaque plot doit être amené à son nouvel emplacement avant que le système ne puisse retourner chercher le plot suivant.Not only the combination of the movements of rotation and translation entails the risk of decreasing system reliability but the positioning of the mandrel above a stud requires great precision, which can only be achieved by greatly slowing down horizontal movements of the mandrel. Especially the moving a series of studs to make a new configuration requires many movements motorized unit and gantry due to the fact that each stud must be brought to its new location before the system can return to find the stud next.
Le dispositif selon la présente invention a pour objectif de remédier à ces inconvénients. Il permet, outre l'utilisation d'une table de type quelconque, de déplacer une série de plots très rapidement et présente un grande fiabilité grâce à la suppression des mouvements de rotation du système de saisie des plots.The device according to the present invention has aim to remedy these drawbacks. It allows, in addition to using a table of any type, move a series of studs very quickly and present high reliability thanks to the elimination of movements rotation of the stud entry system.
Il est constitué d'une table de pressage avec plateau en bois et un portique mobile comportant un magasin de stockage des plots constitués de broches verticales montées sous un rail fixé latéralement sur le portique et sur lesquelles peuvent être enfilés les plots qui comportent un alésage vertical avec billes à ressort assurant leur maintien grâce à des rainures prévues sur les broches, une unité motorisée coulissant sur le rail, destinée à la mise en place, au retrait et au stockage des plots, étant équipée d'une pince mobile verticalement comportant une ouverture latérale en forme de U apte à s'insérer dans des gorges annulaires aménagées à la périphérie des plotsIt consists of a pressing table with wooden tray and a mobile gantry comprising a pad storage store made up of pins vertical mounted under a rail fixed laterally on the gantry and on which the studs can be threaded which have a vertical bore with spring balls ensuring their maintenance thanks to grooves provided on the pins, a motorized unit sliding on the rail, intended for placement, removal and storage studs, being equipped with a vertically movable clamp having a U-shaped side opening suitable for fit into annular grooves fitted at the periphery of the studs
Sur les dessins annexés, donnés à titre
d'exemples non limitatifs de formes de réalisation de
l'objet de la présente demande de brevet :
Le dispositif, figures 1 à 7, est monté sur
une table de pressage 1 comportant un portique mobile 2
perpendiculaire à ladite table et se déplaçant
longitudinalement au-dessus de celle-ci.The device, Figures 1 to 7, is mounted on
a pressing table 1 comprising a
Le plateau 3 de la table de pressage 1 est en
bois,sans rainures, et peut consister par exemple en une
plaque de bois massif, de contreplaqué ou d'aggloméré
recouvrant toute la surface d'une table métallique. Des
plots 4 de maintien des pièces à assembler peuvent être
fixées en position grâce à des pointes 5 disposées à leur
partie inférieure et s'enfonçant dans le bois du plateau.The
Le portique mobile 2 comporte un ou plusieurs
vérins 6 dont l'un au moins peut se mouvoir
transversalement à l'axe longitudinal de la table 1. Le
rôle de ces vérins est d'exercer une forte pression de
haut en bas en direction du plateau 3.The
Après positionnement des plots 4 de maintien,
les pièces constitutives des fermettes 7 sont disposées
sur le plateau 3, les connecteurs 8 sont pré-enfoncés
manuellement, puis le portique mobile 2 et un vérin 6
sont déplacés successivement au-dessus de chaque
connecteur avant d'actionner ledit vérin pour un serrage
définitif.After positioning the
Le portique 2 est équipé latéralement d'un
rail 9 perpendiculaire à l'axe de la table de pressage 1,
sur lequel coulisse une unité motorisée 10 pouvant être
positionnée au-dessus de n'importe quel point du plateau
3. Cette unité motorisée comporte une tige 11 simple ou
double, mobile verticalement et terminée à sa partie
inférieure par une pince 12 constituée d'une platine
horizontale présentant une ouverture latérale en forme de
U déterminée pour pouvoir s'insérer dans des gorges
annulaires 13 aménagées à la périphérie des plots 4.
Cette ouverture comporte un élément élastique 14, tel que
bille à ressort, déterminé pour maintenir un plot dans la
pince 12 tout en permettant son insertion ou son
extraction en exerçant un léger effort.Portico 2 is laterally equipped with a
Au-dessous du rail 9, sont montées plusieurs
broches 15 verticales comportant chacune une série de
rainures circulaires 16 réparties sur sa hauteur. Ces
broches constituent un magasin de stockage des plots 4
qui comportent un alésage vertical permettant de les
enfiler par le bas sur ces broches, soit manuellement,
soit au moyen de la pince 12. Chaque plot est pourvu
d'une bille à ressort 17 interne agencée pour
l'immobiliser à une hauteur déterminée en pénétrant dans
l'une des rainure 16.Below the
Les rainures circulaires 16 peuvent être
remplacées par un épaulement 18 disposé à la base des
broches 15. Lorsque le plot situé au point le plus bas
est retiré, les plots situés au-dessus descendent par
leur propre poids et sont retenus par la bille à ressort
17 du plot inférieur s'appuyant sur l'épaulement. De la
même manière, lorsque un plot est inséré à la base d'une
broche, les plots déjà présents sont repoussés vers le
haut. Ainsi les mouvements de la pince 12 sont
simplifiés, celle-ci n'ayant pas à remonter le long des
broches pour atteindre les plots situés en partie haute
(figure 7).The
L'unité motorisée 10 est agencée de manière à
ce que la pince 12 puisse être positionnée en regard de
n'importe quel plot 4 présent sur une broche 15 et être
insérée dans la gorge annulaire 13, en utilisant
uniquement le mouvement horizontal de l'unité le long du
rail 9 et le mouvement vertical de la pince.The motorized
Ces mêmes mouvements permettent de fixer les
plots sur le plateau 3 aux emplacements déterminés, ou de
les retirer pour les stocker sur les broches verticales
15. Aucune rotation ou mouvement longitudinal de la pince
ne sont nécessaires.These same movements make it possible to fix the
studs on the
Ces broches pourront par exemple être
parallèles entre elles et fixées le long du rail 9, à sa
partie inférieure (figure 3). Dans ce cas, la pince 12
contournera par le bas les broches situées devant celle
sur laquelle se trouve le plot à atteindre et remontera
le long de celle-ci jusqu'à la hauteur adéquate. These pins could for example be
parallel to each other and fixed along the
Dans une variante d'exécution, les broches 15
sont montées sur un barillet tournant, fixé sous le rail
9 et dont la rotation permettra de présenter devant la
pince 12 la broche sur laquelle se trouve le plot 4
choisi.In an alternative embodiment, the
Cette disposition rend possible une réduction
importante de l'amplitude des mouvements de translation
du portique 2 pour modifier une configuration des plots
4, ce qui permet de diminuer très sensiblement la durée
des opérations et par voie de conséquence les coûts de
fabrication. En effet, lors d'une modification de
configuration, tous les plots d'une zone sont retirés et
disposés sur les broches 15 avant d'amener le portique
au-dessus d'une autre zone. On procède de la même manière
pour la mise en place des plots.This provision makes possible a reduction

Les mouvements du portique mobile 2, de
l'unité motorisée 10 et des vérins 6 sont pilotés par un
ensemble électronique pouvant par exemple être installé
dans une armoire montée sur ce portique. Les données
relatives aux positions des plots 4 et des connecteurs 8
pour une série déterminée de fermettes 7 identiques sont
élaborées sur un ordinateur courant, grâce à un logiciel
ad hoc, et transmises par un moyen approprié tel que
câble ou disquette à l'ensemble électronique. La position
de chaque plot 4 de maintien est mémorisée après tout
mouvement, ce qui permettra de le retrouver et de
déterminer le déplacement à effectuer pour une nouvelle
configuration ultérieure.Movements of
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.The positioning of the various elements constitutive gives the object of the invention a maximum useful effects that had not been obtained to date by similar devices.
