Abstract
Needle gripper features a gripper unit with a gripping surface facing a workpiece to grip, and a needle carriage with a gripping needle. The needle carriage moves into an active position extending the gripping needle beyond the gripping surface by one needle stroke depth, and in a passive position retracting the gripping needle, and features a drive unit with a drive actuator driven forward/backward along a drive direction that couples to the needle carriage so it moves into the passive/active positions by driving the drive actuator forward/backward. A setting device for setting the needle stroke depth includes a guide carriage displaceable perpendicularly to the drive direction along a guide direction, and a stop for the guide carriage. The drive actuator couples via connection arm to the guide carriage so when the drive actuator moves backward, the guide carriage moves in the direction toward the stop, which prevents further backwards movement.
