PURPOSE:To vary conveying distance rapidly and easily by providing an introducing member slidably in the longitudinal direction on a slider and adjusting the stroke of said slider by means of an adjustably retractable stopper in the captioned device for electronic parts, etc. CONSTITUTION:A gripper 3 is lowered and, while an object being conveyed is pressed by a conveying claw 2, a slider 7 is moved to the right. At the right end, the gripper 3 is elevated leaving the object, while the slider 7 returns to left. The rightward movement of the slider 7 is carried out by pulling an introducing member 11 rightward through a motor, a cam 17, and a connecting rod 14, and, as the slider 7 is pressed by springs 10, 10', the introducing member 11 is pushed against the right end of a sliding groove 7a of the slider 7. Then the slider 7 is moved leftward following the introducing member which is moved leftward due to the following rotation of the cam 17. The slider 7 is restrained by a stopper 26. Therefore, the conveying distance can be easily varied by varying the position of the stopper 16. |
