Feeding station for electrostatic powdering device

A feeding station for an electrostatic powdering installation comprising at least one spray gun, comprising:

• an enclosure having an opening toward the outside,
• air aspiration and filtration means,
• a support on which at least one powder tank is placed,
• an assembly comprising at least one pneumatic powder pump placed above the support, the pumps being connected, on one side, to a flexible pipe for feeding a gun, and on another side, to a rigid suction pipe for sucking powder from the powder tank, this assembly being mounted on a mechanical module making it possible to move it vertically, means of cleaning an inside of the suction pipes and means (54) of cleaning the outside of the suction pipe being placed beneath the support in vertical alignment with the suction pipe, the support comprising a movable table comprising at least one emplacement for a powder tank and at least one opening allowing passage of the suction pipe and its vertical positioning by the mechanical module close to the automatic means of cleaning the inside of the suction pipes and of the automatic means (54) of cleaning the outside of the suction pipe, an emplacements or an opening capable of being positioned in vertical alignment with the suction pipes by rotation and/or translation of a table in a substantially horizontal plane, wherein the means of cleaning the inside of the suction pipe and the means of cleaning the outside of the suction pipe are placed in a lower compartment situated beneath the enclosure and communicating with the enclosure through an opening made in its lower wall, this opening being left free by the rotating table, when the opening of the table is in vertical alignment with the suction pipe.
