Method and device for automatic formation of bundles of metal laminations
A method for automatically forming bundles of metal laminations, adapted for armatures of electrical machines or the like, by automatic precision dosing of a lamination bundle produced by picking up and separating a preset number of laminations, includes grabbing, at one end of a lamination stack, a preset number of laminations; separating the number of laminations of the bundle from the lamination stack by axially moving the bundle away from the lamination stack by a preset distance; detaching one or more laminations, if any, at the end of the lamination bundle facing the lamination stack, which may have remained adherent to a last intended lamination by being clamped by a part of their thickness or glued to the lowest lamination of the lamination bundle; and collecting the lamination or laminations, if any, detached from the lamination stack end in a position axially aligned with the laminations of the stack.
Device and method for handling elements
A device for handling elements comprises a shank provided with a stop; a rod which is longitudinally movable and rotatable with respect to the shank, comprising a flap at one end thereof, so as to define a clamp between the stop and the flap for gripping an element. A method comprises placing elements separated by at least one slit on a surface; inserting a tip of a shank provided with a flap inside the slit; placing a stop in contact with an upper part of the element; rotating the shank, holding the element on the upper part by the stop and on a lower part by the flap; and separating the element.
