Abstract: The invention relates to a device for providing stopper elements that are sorted in order to feed a downstream workstation. The devices comprising a lifting means; a means or referencing said stopper elements one by one, located downstream from the lifting means; a conveyor for bringing the referenced elements to said workstation, positioned at the outlet of said referencing means; a vision means for verifying the conformance of said elements in an inspection zone extending at the level of the referencing means and/or of the conveyor; and a means for expelling those elements that do not conform located downstream of said vision means. The inspection zone comprises at least two successive sections each including a distinct color. The invention also relates to a corresponding method.
