L'invention a pour objet une panneauteuse destinée à réaliser automatiquement le pliage de tôles (1), selon les plis nécessaires à la formation de panneaux de portes, de cloisonnages ou applications similaires.The invention relates to a panel for automatically performing the folding of sheets (1), according to the folds required for the formation of door panels, partitions or similar applications.
La machine dispose d'un mécanisme de pliage qui comprend un porte-lames (2) disposé, en montage mobile, face à un dispositif d'immobilisation des tôles (1) à plier.The machine has a folding mechanism which comprises a blade holder (2) disposed in a movable configuration facing an immobilization device for the sheets (1) to be folded.
Le dispositif d'immobilisation comprend une partie inférieure (3) ou contre-lame fixée sur le bâti structurel (4) de la machine et un serre-flans supérieur (5) susceptible d'être entraîné verticalement en appui contre la partie inférieure (3) susmentionnée afin d'immobiliser entre l'une et l'autre partie les tôles (1) d'application pour pouvoir réaliser les opérations de pliage.The immobilizing device comprises a lower part (3) or counter-blade fixed on the structural frame (4) of the machine and an upper blank holder (5) capable of being driven vertically in abutment against the lower part (3). ) above to immobilize between the one and the other part the sheets (1) of application to be able to perform the folding operations.
Le porte-lames (2) est disposé en articulation de basculement vertical sur des chariots porteurs (6) montés sur des glissières qui les conduisent vers le dispositif d'immobilisation des tôles (1).The blade holder (2) is arranged in vertical tilting articulation on carrying trolleys (6) mounted on slides which lead them to the plate immobilizer (1).
Les chariots (6) sont unis aux vérins (7) respectifs qui permettent de les faire avancer et reculer tandis que le porte-lames (2) est uni à un ou plusieurs vérins (8) qui assurent le basculement vertical du porte-lames (2) par rapport à l'articulation prévue sur les chariots porteurs (6).The carriages (6) are connected to the respective cylinders (7) which allow them to advance and retreat while the blade carrier (2) is connected to one or more cylinders (8) which ensure the vertical tilting of the blade carrier ( 2) relative to the articulation provided on the carrier trolleys (6).
Le porte-lames (2) est équipé d'un palpeur (9) disposé sur un vérin (10) qui le conduit jusqu'à la partie frontale où se trouve le dispositif d'immobilisation des tôles (1).The blade holder (2) is equipped with a feeler (9) arranged on a jack (10) which leads it to the front part where the immobilizing device of the sheets (1) is located.
Ainsi, la tôle (1) à plier est retenue à l'aide du dispositif d'immobilisation entre le serre-flans (5) et la partie fixe (3), tel qu'illustré sur la
Le porte-lames est entraîné automatiquement par les vérins (7 et 8)en fonction de l'angle de pliage programmé dans le contrôle de la machine, le pliage de la tôle s'effectuant lors d'une première opération selon l'angle programmé, sans dépasser cet angle, après quoi le porte-lames (2) retourne à la position de départ, tel qu'illustré à la
Le vérin(10) entraîne ensuite le palpeur (9) et le conduit jusqu'à la zone de pliage de la tôle (1), tel qu'illustré à la
On réalise ainsi deux mesures sur la partie pliée de la tôle (1), qui permettent d'obtenir avec une précision absolue le résultat de l'angle de pliage, afin que grâce au traitement de cette valeur, et par comparaison avec l'angle réel programmé, le contrôle de la machine adopte la correction nécessaire pour compenser, par une autre opération de pliage, tout défaut éventuel jusqu'à ce que l'on obtienne l'angle exact.Thus two measurements are made on the folded part of the sheet (1), which make it possible to obtain with absolute precision the result of the folding angle, so that by the treatment of this value, and by comparison with the angle programmed real, the control of the machine adopts the necessary correction to compensate, by another folding operation, any possible defect until one obtains the exact angle.
Le serre-flans (5) est disposé sur un chariot (11) articulé sur le bâti structurel (4) de la machine, le chariot (11) en question étant entraîné en basculement par le vérin(12), ce même vérin exerce une pression contre les tôles (1) pour les immobiliser en amenant le serre-flans (5) contre la partie inférieure fixe (3).The blank holder (5) is arranged on a carriage (11) articulated on the structural frame (4) of the machine, the carriage (11) in question being tilted by the jack (12), the same jack exerts a pressing against the plates (1) to immobilize them by bringing the blank holder (5) against the fixed lower part (3).
Le serre-flans (5) se compose de deux blocs d'extrémité et d'un bloc central qui déterminent la longueur du corps du serre-flans (5), le bloc central pouvant être remplacé par des blocs de différentes longueurs, ce qui permet d'adapter la longueur de l'ensemble du serre-flans (5) en fonction de la largeur des tôles (1) d'application pour que l'opération de la machine soit aussi précise que possible dans chaque cas.The blank holder (5) consists of two end blocks and a central block which determine the length of the blank holder body (5), the central block being replaceable by blocks of different lengths, which allows to adapt the length of the entire blank holder (5) according to the width of the sheets (1) application so that the operation of the machine is as accurate as possible in each case.
A cet effet, le porte-lames (2) est équipé d'un chariot (13) qui permet de remplacer automatiquement le bloc central du serre-flans (5) en fonction de la largeur des tôles (1) à plier avec la machine dans chaque cas, de telle sorte que le chariot (13) se déplace et saisisse au passage le bloc central du serre-flans (5) pour le conduire à un magasin (non représenté) contenant plusieurs blocs semblables, de différentes longueurs, où le chariot (13) en question prend le bloc de longueur appropriée, l'emmène ensuite jusqu'au serre-flans (5) et le dépose au centre de celui-ci.For this purpose, the blade holder (2) is equipped with a carriage (13) which makes it possible to automatically replace the central block of the blank holder (5) as a function of the width of the sheets (1) to be folded with the machine in each case, so that the carriage (13) moves and grasps the central block of the blank holder (5) as it passes to a magazine (not shown) containing a plurality of similar blocks of different lengths, where the trolley (13) takes the block of appropriate length, then takes it to the blank holder (5) and places it in the center of it.
Le chariot (13) est entraîné par un vérin (14) commandé par le contrôle de la machine, ledit vérin (14) pouvant être un vérin indépendant, servant uniquement à déplacer le chariot (13); mais on a prévu également la possibilité d'utiliser pour cette fonction le vérin (10) du palpeur (9), auquel cas le chariot (13) serait associé audit vérin (10) par rapport au contrôle correspondant pour réaliser cette fonction de changement du bloc central du serre-flans (5).The carriage (13) is driven by a jack (14) controlled by the control of the machine, said jack (14) being an independent jack, serving only to move the carriage (13); but it is also possible to use for this function the cylinder (10) of the probe (9), in which case the carriage (13) would be associated with said cylinder (10) relative to the corresponding control to perform this function of changing the central block of the blank holder (5).
