Thickness adjustable material detector for gripper mechanism

摘要

The spacing between jaws on a gripper lever is gauged by a sensing rod movably mounted on the lever to actuate a limit switch supported in a switch housing clamped to the oscillatory shaft to which the gripper lever is attached. The limit switch is adjusted to detect deviations from the thickness of a single sheet of material clamped between the jaws during transfer from a magazine to a collating conveyor.
