Abstract
A high-speed bar feeding system for automatically feeding long non-cylindrical (concrete) reinforcing bars wherein the bars are removed from a bundle, placed in a single row on an inclined feed ramp having a multiplicity of support rolls and overhead retaining means adjacent the upper surfaces of the bars, the bars are transferred several at a time from the ramp to a conveyor adjacent the ramp having driven cylindrical rolls and a series of spaced fanning magnets located between the conveyor rolls which position the bars with a predetermined spacing, and the bars are advanced to magnetic drive rolls having several V-grooves to receive the bars and guide them through a cut-off machine to a retractable length gauge. Unique escapement means are employed to lift the bars comprising a series of arms which swing from an inclined retracted position below the conveyor rolls to an inclined raised position wherein the several bars move laterally off the feed ramp by gravity to a position above the conveyor rolls. Each escapement arm has a multiplicity of support rolls to facilitate movement of the non-cylindrical bars and has an escapement plate to engage the first of the remaining bars on t…
