Abstract
A device for disentangling bundles of concrete-reinforcing steel bars comprises a storage bed composed of a number of frame units each of which defines a respective upwardly opening V-shaped recess, the bars being received in the recesses and the frame units being spaced apart longitudinally of the bars with the recesses mutually aligned. A plurality of lifters intermesh with the frame units, each lifter being vertically movable in a space defined between a respective adjacent pair of the frame units and including a middle part having a flat upper surface whose width perpendicular to the bars is intermediate the width of an upper end of each recess and the width of a lower end of each recess. Means is also provided for raising and lowering the lifters.

A device for disentangling bars, comprising a storage bed composed of a number of frame units each of which defines a respective upwardly opening V-shaped recess, said bars being received in the recesses and said frame units being spaced apart longitudinally of said bars with the recesses mutually aligned, a plurality of lifters which intermesh with said frame units, each said lifter being vertically movable in a space defined between a respective adjacent pair of said frame units and including a middle part having a substantially horizontal flat upper surface for supporting at least a portion of the disentangled bars whose width perpendicular to the longitudinal axis of said storage bed is intermediate the width of an upper end of each recess and the width of a lower end of each recess, and means for raising and lowering said lifters.
A device for disentangling bars, comprising a storage bed composed of a number of frame units each of which defines a respective upwardly divergent recess, said bars being received in said recesses and said frame units being spaced apart longitudinally of said bars with said recesses mutually aligned, a plurality of lifters which intermesh with said frame units, each said lifter being vertically movable in a space defined between a respective adjacent pair of said frame units and including a middle part having a flat upper surface whose width perpendicular to the longitudinal axis of said storage bed is intermediate the width of an upper end of each recess and the width of a lower end of each recess, means for raising and lowering said lifters, a plurality of wedge-shaped pusher members each of which is upwardly pointed to form an upper apex, each said pusher members being disposed in a respective one of said lifters and being vertically movable relative thereto into and out of a position in which said apex of said pusher member is below said flat upper surface of said respective one of said lifters, and means for preventing movement of each said pusher member out of said position prior to commencement of upward movement of said respective ones of said lifters.
A device for disentangling bars, comprising a storage bed composed of a number of frame units each of which defines a respective upwardly divergent recess, said bars being received in said recesses and said frame units being spaced apart longitudinally of said bars with said recesses mutually aligned, a plurality of lifters which intermesh with said frame units, each said lifter being vertically movable in a space defined between a respective adjacent pair of said frame units and including a middle part having a substantially flat upper surface whose width perpendicular to the longitudinal axis of said storage bed is intermediate the width of an upper end of each recess and the width of a lower end of each recess, and means for raising and lowering said lifters, the middle part of each said lifter being provided with a roller which is rotatable about an axis perpendicular to the longitudinal axis of said storage bed and which has raised lateral faces, and means is provided for driving said roller in a bar conveying direction parallel to the longitudinal axis of said storage bed.
