Manipulator device for a bending machine and a method for changing the position of the workpiece in a bending process
First Claim
1. A manipulator device for a bending machine which includes an elongate die and punch set for bending a workpiece comprising:
- a first manipulator having,a first clamping means for clamping the workpiece to be bent,a first support means for supporting the first clamping means in a rotatable manner around a rotary axis parallel to the longitudinal direction of the punch and die, anda second support means for supporting the first support means in a movable manner in a X-axis direction parallel to the longitudinal direction of the punch and the die, in a Y-axis direction perpendicular to the X-axis direction, and in a Z-axis direction parallel to the vertical direction; and
a second manipulator having,a second clamping means for clamping the workpiece,an arm means for supporting the second clamping means, anda column means for supporting the arm means in a rotatable manner around a rotary axis parallel to the Y-axis, the column means being so constructed as to be movable toward and away from the first manipulator.

Abstract
A manipulator device for a bending machine includes a pair of elongate die and punch for bending a workpiece. A first manipulator has a first clamping device for clamping the workpiece to be bent, a first support for supporting the first clamping device in a rotatable manner around a rotary axis parallel to the longitudinal direction of the punch and die, and a second support for supporting the first support in a movable manner in a X-axis direction parallel to the longitudinal direction of the punch and die, in a Y-axis direction perpendicular to the X-axis direction, and in a Z-axis direction parallel to the vertical direction. A second manipulator has a second clamping device for clamping the workpiece, an arm for supporting the second clamping device, and a column for supporting the arm in a rotatable manner around a rotary axis parallel to the Y-axis, the column being so constructed as to be movable toward and away from the first manipulator.

13. A method of automatically changing orientation of a workpiece with respect to a bending machine for bending the workpiece in order to perform bendings on opposite longitudinal edges and in opposite directions in the workpiece to form a processed workpiece, comprising the steps of:
-
placing the workpiece in front of the bending machine with a longitudinal edge of said workpiece disposed parallel to a horizontal bending axis of the bending machine; clamping the workpiece along the opposite longitudinal edge thereof by means of a clamping means; rotating the clamping means and the workpiece gripped thereby about a horizontal axis perpendicular to the bending axis of the bending machine; moving the clamping means toward the bending machine in order to transfer the workpiece to another clamping means; moving the other clamping means in the vertical direction and toward the clamping means in order to receive the workpiece from the clamping means; clamping the workpiece by means of the other clamping means along a shorter edge of the workpiece; rotating the other clamping means and the workpiece gripped thereby about a horizontal axis parallel to the bending axis of the bending machine; and moving the other clamping means and the gripped workpiece in the direction parallel to the bending axis in order to unload the processed workpiece.
