Abstract

L'objet de la présente invention est de proposer une technologie avec laquelle, lors du transport d'une borne équipée d'une bande, une partie de borne et une paire de mâchoires de préhension n'interfèrent pas facilement l'une avec l'autre, même lorsque la paire de mâchoires de préhension a saisi la bande à partir du côté partie de borne. Ce dispositif de transport de borne transporte une borne équipée d'une bande qui est découpée à partir d'une borne continue. Le dispositif de transport de borne est doté d'un premier mécanisme de transport qui comprend une partie de préhension et un mécanisme de déplacement de partie de préhension. La partie de préhension a une paire de mâchoires de préhension qui saisit une première partie de la bande de la borne équipée d'une bande et est disposée de façon à être apte à transporter la borne équipée d'une bande d'une position d'origine à une position de distribution. La partie de préhension est disposée de telle sorte qu'un espace est formé au niveau d'une partie intermédiaire lorsque les pointes de la paire de mâchoires de préhension ont saisi la bande de la borne équipée d'une bande. Le mécanisme de déplacement de partie de préhension est disposé de manière à être capable de déplacer la partie de préhension en va-et-vient de la position d'origine à la position de distribution.
