Abstract
(EN)
ABSTRACT In a powder supplying device, a powder container contains powder therein and is provided at a bottom of the powder container with a gas blowout part for ejecting gas to the inside of the powder container. A powder transport unit attracts powder contained in the powder container from a suction opening and transports the powder to a powder receiving device. A first detection unit is provided in the powder container to detect a remaining powder in the powder container.

Selon l'invention, dans un dispositif de fourniture de poudre, un récipient de poudre contient une poudre dans celui-ci et est pourvu au fond du récipient de poudre avec une partie de soufflage de gaz pour éjecter un gaz vers l'intérieur du récipient de poudre. Une unité de transport de poudre attire la poudre contenue dans le récipient de poudre depuis une ouverture d'aspiration et transporte la poudre vers un dispositif de réception de poudre. Une première unité de détection est disposée dans le récipient de poudre pour détecter une poudre restante dans le récipient de poudre.
