Title:
複動形エアシリンダの位置決め制御機構
Document Type and Number:
Japanese Patent JP4353335
Kind Code:
B2
Abstract:
Between an air source and first and second pressure chambers of a double-acting main cylinder having a length measurement sensor for measuring an acting position of a piston, a first supply solenoid valve and a second supply solenoid valve are connected, respectively, while between the first and second pressure chambers and the atmosphere, a first exhaust solenoid valve and a second exhaust solenoid valve are connected, respectively. When a target acting position of the piston is inputted into a controller, the controller moves the piston to the target acting position so that a position measured by the length measurement sensor agrees with the target position by on-off controlling the solenoid valves. Upon reaching the target position, the piston is stopped and held in the stopped state by confining air within the pressure chambers.
