Abstract
Two pairs of arms are parallel to and spaced apart from one another and lie eneath the path of a conveyor for advancing slab materials to be turned over, one pair of arms moves upwardly while remaining horizontal and engaging the slab whereupon the arms advance to a vertical position, followed by the other pair of arms which swing into a verical position in a sense opposite to that of the first pair of arms for receiving the slab and lowering it to the conveyor in a turned over position, both pairs of arms being driven through a series of articulated connecting rods and levers coupled to either electric or hydraulic drives.
Claims6
A lever-operated turn-over device for slabs displaced by a conveyor along a path comprising:
- a first pair of movable elongated arms mounted parallel to one another and arranged beneath the path of said conveyor in a horizontal position;
- a second pair of swingable elongated arms lying in planes parallel to said first pair of arms;
- each of said first pair of arms having a wheel mounted at a first end thereof;
- a track engaging each of said wheels and forming a guide therefor;
- a drive means articulated to said first end of each of said first pair of arms for moving said arms along said tracks into said conveyor path and engagement with said slab to lift said slab from said conveyor;
- another articulation between said drive means and a second end of each of said first pair of arms for swinging said first arms about said wheels into a vertical position and beyond;
- and
- a further articulation between said drive means and said second pair of arms for swinging said second pair into a vertical position adjacent said first pair of arms for receiving said slab therefrom and returning said slab to said conveyor in a turned-over position.
