DEVICE FOR FILLING TONER FROM A TRANSFER CONTAINER INTO A TONER STORAGE CONTAINER

摘要

To transfer the toner (21) from a storage vessel (20) into the toner storage container, a depression is created in the latter by means of a suction fan. The toner storage container is connected via a flexible pipe to an inseparable suction spout in the transfer container. The spout comprises an internal tube (29) communicating with the flexible pipe, and an external tube (31) which totally surrounds at a distance the inner tube (29), is open to the atmosphere in its upper part and is provided in its lower part with inlet openings (33) for the toner. The through-flow of air draws the toner through the toner inlet openings (33). The toner storage tank itself is divided into a deposit area and a suction area, which are separated by a filter. As a result of the through-flowing air stream the filter becomes arched. The inversion of the arch causes the detachment of the toner (21) adhering thereto, which then falls into the deposit area.
