Accordingly, air cylinders present several problems such as difficulty controlling the speed accurately and the cylinder operation being affected by the load. ROBO Cylinders offer many ways to solve these problems associated with air cylinders. Sample solutions are explained below. ROBO Cylinder General Catalog Problem with air cylinders Solution offered by ROBO Cylinders Positioning operation Desired target positions can be set with ease. Position alignment, setup change and other tasks are also easy. Difficult to adjust acceleration/ deceleration Overshooting during downward movement or large shock at higher speed may damage the work. Acceleration/deceleration adjustment Acceleration/deceleration can be set in fine steps to suppress shock and eliminate the possibility of work damage. Speed change during movement Positioning operation Difficult to perform positioning to multiple points Movement between two points is the mainstream pattern of positioning operation with air cylinders. If the number of stopping points is increased to three or more, a special mechanism must be provided. Even with a special mechanism, the number of positioning points is still limited. Speed/ acceleration adjustment Difficult to fine-tune speed Since fine-tuning of speed is difficult, the speed may be increased excessively to damage the work, or decreased excessively to affect the tact time. Fine-tuning of speed Speed can be finely adjusted in 1-mm/s steps. This eliminates the possibility of work damage and also minimizes the tact time. Difficult to change speed during movement Changing speed is difficult during movement. Speed is also not stable. Speed change during movement Speed can be changed easily during movement. Since ROBO Cylinders adopt servo control by means of motor/ball screw drive, travel speed can be kept constant. Push-motion operation Works cannot be pushed properly If the push force is too strong, the work may be damaged. Lowering the push speed to prevent damage will affect the tact time. Push-motion operation The speed is reduced before the actuator contacts the work, and the push force can be adjusted easily. Push force cannot be adjusted properly Push force must be adjusted constantly using a regulator (reducing valve), etc., and the adjusted force still fluctuates. Push force adjustment Push force can be adjusted easily using position data, and the adjusted push force remains constant. Zone output A sensor is needed to issue an output signal To issue an output signal, a sensor must be installed at the desired position and the signal must be turned ON/OFF. Zone output An area signal can be output through easy setting without using a sensor. (This signal can be used to prevent contact and for various other purposes.)
