Abstract

Abstract An article taking out apparatus for taking out articles in a one-by-one from a group of articles left irregularly. The apparatus comprises a gripper having a plurality of gripper fingers which are pivotally secured to a gripper body at their one ends and carries respective contact sensors at their free ends. The gripper is carried by a transporting section which is adapted to move the gripper horizontally and vertically. A sensing section is adapted to receive the signals from the contact sensors. A drive control section is adapted to control the driving of the gripper and the transporting section. The gripper and the transporting section are driven in accordance with the signals from the contact sensors to search out the surfaces of an article to be gripped and to grip the article at the searched surfaces.
