Abstract
A powder-bag emptying unit for powder spray coating facilities, comprises a bag-receiving hopper which is designed to receive a powder bag. The bag-receiving hopper is narrower at its bottom than at its top. The hopper wall keeps the powder bag dimensionally stable and in a fixed position in which a bag aperture is situated at the top end of the bag. The bag-receiving hopper is fitted at its lower end at the hopper center with a hopper opening which is open downward and permits coating powder to drop out of it. The bag-receiving hopper further is fitted with at least one vibrator to shake the bag-receiving hopper.
