The device is applied in machine building for assembly and pallet placement of screws and discs, an in particular of spring discs. It ensures high reliability in assembly and pallet placement. The device includes a furrow (2) for discs (10), which is two-channel and a furrow (3) for screws (4). The furrow (2) for discs (1) lies on a conical plane (36) with a generant (35) close to the vertical, while its edge lies in a plane close to the horizontal. Above is it fitted an elastic brush (8). In a vertical plane, parallel to the end of the furrow (2) is placed a lever mechanism (20,21,22,23) to the connecting rod (21), on which via a lever (10) are attached two graspers (9) describing a closed curve (5) with a horn point. The furrow (3) for screws (4) is located on the tangent (31) in the horn point. At the moment of assembly, the axis of the screw (4) is parallel to the end of the furrow (2). In the horizontal plane perpendicular to the plane of the lever mechanism, two pallets (11) are placed, which are tangently connected to a point from the closed curve (5). The axes of the pallets (11) are hinged to the shafts of engines (25), connected to a body (26), carrying out a translation perpendicular to the plane of the lever mechanism. The openings of the pallets (11) are fitted along concentrical to the axis (39) contours (34) in two rows, at a distance corresponding to the graspers (9). The realm of palletising is angular and lies in the plane of the openings (28).
