Abstract (en)
[origin: EP0652063A1] This device comprises a rigid chassis (12) having a vertical axis of symmetry (X) forming a virtual axis of oscillation of the chassis, defined by the intersection of the longitudinal and transverse vertical median planes of the chassis, this chassis being attached to a stationary support (14) by elastically deformable linking means (16). The knock-out device comprises, moreover, two devices (24) for gripping components to be knocked out, which are carried by two opposite ends of the chassis (12), being aligned in the median longitudinal plane, and two unbalance (unbalanced mass) motors (26) fixed on two opposite sides of the chassis (12), having axes of rotation parallel to the axis of symmetry (X) of the chassis (12) and aligned with this axis of symmetry in the transverse median plane, the motors (26) being intended, when operating, to make the chassis (12) oscillate about its virtual axis (X) so that the centre of gravity of each component to be knocked out describes a substantially horizontal and ellipsoid trajectory. <IMAGE>
