A.1.3 Example of "Gripper feed"
The example shows a press to which the material is fed by means of a gripper feed
mechanism.
At the angular position of 300°, the gripper closes and moves the material up to the
angular position 150°.
The gripper remains closed during the press operation and opens again at 200°.
The gripper feed returns to its home position, starting at angular position 200°, up
to angular position 270°.
The motion of the feed axis is directly proportional to the rotary movement of the
die axis. Because of this, the feed axis is coupled to the die axis by means of a
cam disk technology. The opening (at 200°) and closing (at 300°) movement of the
gripper tool is controlled with the help of a cam switching function.
