Conveying device for conveying a workpiece

A machine tool, comprising:

• a first machine slide configured for linear movement in a first longitudinal direction;
• a second machine slide configured for linear movement in a second height direction and a third transverse direction, the first longitudinal direction, the second height direction and the third transverse direction each being perpendicular to each other;
• a transport device operably coupled to the second machine slide, the transport device configured to transport at least a sectionwise rod-shaped workpiece that has a workpiece longitudinal axis between a clamping chuck and a workpiece carrier of the machine tool, the transport device comprising:
• a gripper arrangement including a pivot arm that is arranged, on one end, on a first pivot drive, such that the pivot arm is pivotally supported on the machine tool so as to be pivotable about a first pivot axis and the pivot arm has, on its other end, a second pivot drive on which a workpiece gripper for gripping the workpiece is pivotally supported so as to be pivotable about a second pivot axis, the workpiece gripper defining a gripper axis that is inclined by 45° to the second pivot axis in each position of the gripper axis as it pivots about the second pivot axis, and the gripper axis coincides with the workpiece longitudinal axis when the workpiece is held by the workpiece gripper;
• a control arrangement for activating the first and second pivot drives;
• wherein the first pivot axis extends in a longitudinal direction and the second pivot axis is inclined by 45° relative to the longitudinal direction;
• wherein the workpiece gripper is moved between a first position and a second position by the second pivot drive, which pivots the workpiece gripper about the second pivot axis;
• wherein the workpiece longitudinal axis extends, in the first position of the workpiece gripper, at a right angle with respect to the longitudinal direction and extends, in the second position of the workpiece gripper, parallel to the longitudinal direction;
• and
• wherein the distance of the workpiece gripper from the first pivot axis in the first position is smaller than in the second position.
