Abstract
An apparatus for manipulating the orientation of a metal bloom supported on a conveyor, the bloom being elongated and substantially square in cross section, comprising a conveyor, including rollers, disposed along a generally horizontal path, an upright abutment located adjacent the path, and a pivotable arm traversing the path having a free end with a first workpiece engaging surface located to intercept the path and receive and support a workpiece from the conveyor, the surface extending laterally from the path beyond the abutment and a second workpiece engaging surface laterally offset from the path beyond the abutment and extending above the first surface.
Claims16
An apparatus for reorienting a metal bloom supported on a conveyor, said bloom being elongated and substantially square in cross section and positioned in a first orientation and at a first location on the conveyor, comprising
- a conveyor, including rollers, disposed along a generally horizontal path,
- an upright abutment located adjacent said path,
- a pivotable arm traversing said path having a free end with a first workpiece engaging surface located to intercept said path and engage the underside of a bloom at a location where the bloom is supported by said conveyor, said first surface extending laterally from the path beyond said abutment and a second workpiece engaging surface laterally offset from the path beyond said abutment and extending above the first surface, and
- an actuator for raising the first surface from a first position to a second position to raise the bloom from the conveyor, shift it laterally, lower it and return it to said first location.
- wherein said abutment extends vertically above said first surface at a location to engage and tilt a laterally shifted bloom about a longitudinal axis of the bloom as said first surface is returned to said first position.
An apparatus for manipulating the orientation of steel workpieces, comprising
- a conveyor defining a path of workpiece travel, said conveyor comprising spool-shaped rollers spaced along the path, the rollers each having a cylindrical base, two spaced flanges and a V-shaped peripheral notch in the base midway between the flanges, and
- at least two pivotable arms spaced along the path, each having a free end, a first surface at the free end located to underlie the path in a first position of the arms and to intercept the path when the arms are pivoted from the first position, and on which the workpiece is supportable and slidable, and a second surface extending at an angle of at least 90 degrees from the first surface,
- whereby when the arms are pivoted from the first position where the first surface underlies the path to a second position above the path and then returned to the first position, the workpiece engages one of the flanges and is positioned on the rollers in a rotated orientation which is rotated 45 degrees from the original orientation.
A method of manipulating the orientation of steel workpieces, comprising the steps of
- transporting workpieces along a path on a conveyor including rollers disposed in said path, the workpieces being positioned in an original orientation on the rollers to have a surface supported by the rollers,
- selecting for rotation one of the workpieces disposed at a particular location along said path,
- supporting the workpiece on a pivotable arm having a free end adapted to receive the workpiece from the conveyor,
- pivoting the arm in a first direction about a point at substantially the midpoint of the arm sufficient to cause the workpiece to slide on the end of said arm,
- pivoting the arm in a second direction about said point to rotate the workpiece on the end of said arm toward the conveyor to cause the workpiece to contact an abutment located adjacent the conveyor path and to rotate from the original orientation into a rotated orientation in which the workpiece is rotated with respect to the original orientation, and
- positioning the workpiece on the rollers at said location in the rotated orientation.
A method of manipulating the orientation of steel workpieces, comprising the steps of
- transporting workpieces along a path on a conveyor, the conveyor including rollers disposed in said path on which a workpiece is positioned in an original orientation,
- supporting a workpiece on a pivotable arm having a free end adapted to receive the workpiece from the conveyor,
- pivoting said arm in a first direction away from the conveyor to lift the workpiece from the conveyor sufficient to cause the workpiece to slide on the end of said arm,
- pivoting said arm in a second direction toward the conveyor to cause the workpiece to strike an upright flange member located adjacent the conveyor path and to rotate from the original orientation into a rotated orientation in which the workpiece is rotated with respect to the original orientation, and
- supporting the workpiece on the rollers in the rotated orientation.
Apparatus for reorienting a bloom supported on a conveyor, said bloom being elongated and substantially square in cross section and positioned in a first orientation and at a first location on the conveyor, comprising
- a movable support having a surface for engaging the underside of a bloom at a location where the bloom is supported by a conveyor,
- an actuator for raising the surface from a first position to a second position to raise the bloom from the conveyor, shift it laterally, lower it and return it to said first location, and
- an abutment located adjacent said conveyor and extending vertically above said movable support at a location to engage and tilt a laterally shifted bloom about a longitudinal axis of the bloom as said surface is returned to said first position.
A method of reorienting a bloom supported on a conveyor, said bloom being elongated and substantially square in cross section, the steps comprising
- raising the bloom from a conveyor,
- shifting the bloom laterally while raised,
- lowering the bloom back toward the conveyor,
- contacting the bloom with an abutment located adjacent the conveyor,
- rotating the bloom about its longitudinal axis as it is lowered back to the conveyor, and
- lowering the bloom back to an original location on the conveyor.
