Abstract
A pneumatic cylinder device having a decleration mechanism. The pneumatic cylinder device has a pneumatic cylinder including a cylinder accomodating a piston movable in the cylinder in response to supply and discharge of compressed air and having a connected piston rod. The pneumatic cylinder further includes a position detector such as a combination of proximity switches and a magnet carried by the piston designed for producing a deceleration signal and a stopping signal when the piston rod has reached a predetermined deceleration starting position and a designated stopping position, respectively. A brake which is connected to the pneumatic cylinder is adapted for stopping the movement of the piston rod in response to the stopping signal produced by the position detector. The pneumatic cylinder device further comprises a deceleration stage connected to the brake and adapted for decelerating the piston rod in response to the deceleration signal produced by the position detector.
