Abstract

L'invention concerne un dispositif de montage de composants comprenant : une base ; une palette qui est disposée de façon détachable sur la base et maintient un dispositif d'alimentation de bande ayant un mécanisme d'entraînement qui est en prise avec une bande de support stockant sur celle-ci une pluralité de composants de façon à fournir la bande de support dans une direction d'alimentation prescrite ; une unité de détection qui détecte l'exécution d'un travail pour retirer la palette de la base ; et une unité de commande qui commande, lors de la détection par l'unité de détection de l'exécution de travail pour retirer la palette, le mécanisme d'entraînement du dispositif d'alimentation de bande, et enroule la bande de support dans une direction inverse à la direction d'alimentation.
