Abstract

A chuck unit includes a first pressure chamber and a second pressure chamber disposed on both sides of a piston for driving fingers. A valve unit includes a first output air flow path connected to one of the first and second pressure chambers, a second output air flow path connected to the other thereof, a first solenoid valve connected to the first output air flow path, and a second solenoid valve connected to the second output air flow path. The first solenoid valve connects the first output air flow path to an air supply source when energized and opens the first output air flow path to atmosphere when de-energized, and the second solenoid valve opens the second output air flow path to atmosphere when energized and connects the second output air flow path to the air supply source when de-energized.
