Patent

CA 2473415

Veneer sheet lay-up apparatus (10) with rearward and forward tablets (102, 202), about which rearward and forward conveyors (112, 212) are respectively entrained. A controller (302) longitudinally reciprocates the tablets toward and away from one another, between open and closed configurations. A veneer sheet (22) delivered to the rearward tablet is forwardly conveyed to the forward tablet, which forwardly conveys the sheet's forward portion. The controller detects the sheet's arrival at the desired lay-up position and thereupon simultaneously rearwardly retracts the rearward tablet and forwardly advances the forward tablet from beneath the sheet, creating a lay-up space into which the veneer sheet is gravity-displaced.

L'invention concerne un appareil de superposition de feuilles de placage (10) comprenant des blocs avant et arrière (102, 202) autour desquels sont entraînés des transporteurs avant et arrière (112, 212). Une commande (302) imprime un mouvement longitudinal de va-et-vient qui rapproche et éloigne lesdits blocs l'un de l'autre, les faisant passer d'une configuration ouverte à une configuration fermée. Une feuille de placage (22) amenée vers le bloc arrière est transportée d'arrière en avant vers le bloc avant, lequel transporte d'arrière en avant la partie avant de la feuille. La commande détecte l'arrivée de la feuille sur la position de superposition souhaitée, puis simultanément, retire d'avant en arrière le bloc arrière et fait avancer le bloc avant situé sous la feuille, créant ainsi un espace de superposition dans lequel la feuille de superposition est déplacée par gravité.
