Abstract:
1. An apparatus for the intermittent feeding of a workpiece, the apparatus comprising: a first linearly guided gripper mechanism which is movable in a first direction of workpiece feeding and in a second direction opposite to the first direction, the first gripper mechanism comprising a first gripping member and a second gripping member wherein the second gripping member is movable relative to the first gripping member for gripping the workpiece; a gripper mechanism drive actuator which is angularly adjustable, reversible and rotary; and, a fixed length driving member connected to the gripper mechanism drive actuator for rotation therewith; a first gripper mechanism drive connecting link with a first end pivotally connected to a first end of the fixed length driving member and with a second end pivotally connected to the first gripper mechanism for moving the first gripper mechanism in the first direction of workpiece feeding and the second direction opposite to the first direction; a first release actuator for moving the second gripping member of the first gripper mechanism in a direction relative to the first gripping member of the first gripper mechanism; and a first release connecting link with a first end pivotally connected at a first pivot axis to the first release actuator and with a second end pivotally connected at a second pivot axis to the second gripping member of the first gripper mechanism, wherein the second pivot axis of the first release connecting link is movable in the first direction of workpiece feeding and the second direction opposite to the first direction.
