Bar accumulating apparatus

Claim 2

Mechanism for the accumulation of elongated bars comprising a frame, a linear series of bar guide rolls, a series of baraccumulating conveyors spaced along said series of rolls and extending laterally therefrom, like ends of said conveyors being spaced laterally from said rolls, an elongated support member pivotally mounted on said frame on an axis extending in a direction lengthwise of said series of rolls and located below said like ends of the conveyors, a series of transfer arms mounted on said support for pivotal movement about an axis extending parallel to said support pivot axis, the free ends of said arms being normally positioned intermediate said rolls below a bar positioned thereon, reversible power means connected to said support and said arms, and a control circuit including means for controlling the reversible power means and operable to effect upward movement of said arms about their pivotal mounting to elevate a bar from said rolls followed by lateral movement of said support and arms toward said conveyors to deposit the bar thereon and effect return movement of said arms to normal position.

Claim 3

Mechanism as set forth in claim 1 and including power means operable to effect movement of said conveyors in a direction away from said rolls prior to the transfer of each bar from said rolls to said conveyors, said power means being inoperable during deposit of the bar on said conveyors.

Claim 4

Mechanism for accumulating elongated bars comprising a frame, a linear series of bar-supporting guide rolls mounted on said frame, power means operable to effect advancement of a bar along said rolls to a transfer position, a series of conveyors spaced along said series of rolls and extending laterally therefrom, like ends of said conveyors terminating adjacent said series of rolls, a support extending in a direction lengthwise of said series of rolls and being mounted on the frame for pivotal oscillation toward and from said rolls, the axis of said pivotal mounting being located below said like ends of the conveyors, a series of transfer arms pivotally mounted at like ends to said support, said arms normally extending toward said rolls with the free ends of said arms positioned intermediate said rolls below a bar positioned thereon, first reversible power means connected to said arms and operable to effect upward movement of the free ends thereof for elevation of a bar from said rolls, a second reversible power means connected to said support and operable to move the same in a direction away from said series of rolls for transfer of said elevated bar over said conveyors, a control circuit for said first and second reversible power means including means for timing said reversible power means to have the arms move upwardly before the support moves to assure initial lift of a bar, said power means being reversible to return the free ends of said arms to normal position, and means operable to Move said conveyors in a direction away from said rolls.

Claim 5

Mechanism for accumulating elongated bars comprising a frame, a linear series of bar-supporting guide rolls mounted on said frame, power means operable to effect advancement of a bar along said rolls to a transfer position, a series of conveyors spaced along said series of rolls and extending laterally therefrom, like ends of said conveyors terminating adjacent said series of rolls, a support extending in a direction lengthwise of said series of rolls and being mounted on the frame for pivotal oscillation toward and from said rolls, the axis of said pivotal mounting being located below said like ends of the conveyors, a series of transfer arms pivotally mounted at like ends to said support, said arms normally extending toward said rolls with the free ends of said arms positioned intermediate said rolls below a bar positioned thereon, first reversible power means connected to said arms and operable to effect upward movement of the free ends thereof for elevation of a bar from said rolls, a second reversible power means connected to said support and operable to move the same in a direction away from said series of rolls for transfer of said elevated bar over said conveyors, a control circuit for said first and second reversible power means including means for timing said reversible power means to have the arms move upwardly before the support moves to assure initial lift of a bar, said power means being reversible to return the free ends of said arms to normal position, and means operable to Move said conveyors in a direction away from said rolls.

Claim 6

Mechanism as defined in claim 3, wherein said control circuit further includes means to cause lowering of said transfer arms to transfer a bar onto said conveyors prior to reversing movement of said support to return said arms to normal position.
