A unit for the automatic loading of sheet units onto functional machines equipped with a conveyor which comprises a base frame which can be moved on corresponding rails along a track parallel to the direction of advance of the conveyor member of the machine to which the unit is connected, and a frame bearing one or more members for picking up sheet units, transported by the base frame, equipped with elements for movement comprising elements effecting horizontal lateral movement in a direction perpendicular to the direction of movement of the base frame and element effecting vertical displacement together achieving a displacement between a pick-up position over an area in which sheet units are accumulated and a setting-down position overlying the conveyor in which extreme positions the picked up sheet unit lies substantially horizontal with an intermediate position in which the sheet unit picked up lies in an inclined position, together with controllable elements for translational coupling between the conveyor member and the first frame.

A unit for the automatic loading of sheet units comprising: a conveyor having a direction of advance; a plurality of rails defining a track parallel to the direction of advance of the conveyor; a base frame movable on said rails; a second frame bearing one or more members for picking up said sheet units, carried by the base frame; drive means for movement of said frames comprising means for moving said base frame parallel to said direction of advance, means for horizontal movement of said second frame in a direction perpendicular to the direction of movement of the base frame and means for vertical movement of said members, said means for horizontal and vertical movement together effecting displacement of said members between a pickup position overlying an area in which sheet units are accumulated and a setting-down position overlying the conveyor, in which extreme positions the sheet unit picked up lies substantially horizontal, with an intermediate position in which the sheet unit picked up lies at an inclined angle; controllable means for translational coupling between the conveyor and the first frame, said base frame constituting a first flat frame, lying horizontally, which can be moved on respective rails parallel to the direction of advance of said conveyor, said first frame being equipped with a central opening within which are located two cross-members can rotate about axes parallel to the direction of advance of the conveyor, the cross-member closest to the conveyor being connected by means of an articulated joint, having its axis offset from the axis of rotation of the cross-member itself, to one end of a second frame bearing one or more members for picking up a sheet unit, the opposite end of the second frame resting slidably on the other cross-member in a position offset from the axis of rotation thereof, together with actuators which rotate independently of the cross-members through a predetermined angle for moving the pickup members linked by articulations to the cross-members vertically and horizontally between a pickup position above an area in which sheet units are accumulated and a setting-down position overlying the conveyor.
