Disclosed is a blank gripper attached to an arm of a blank transporting robot, which places a blank into a mold to grip the blank. The disclosed blank gripper comprises: a frame connected to an arm of the blank transporting robot; a gripping unit fixated on the frame to grip both parts of a front and rear of the blank, and have a pair of grippers respectively having a gripping arm which rotates in between a gripping position to grip the blank and a releasing position to release the grip of the blank; and a hole detecting unit fixated on the frame to detect a standard hole formed on the blank when the blank is gripped. The hole detecting unit comprises: a main frame; a detecting rod installed to penetrate the main frame and be able to vertically move to be inserted into a standard hole of the blank when gripping the blank; a detecting bump placed on one side on top of the detecting rod; and a proximity sensor installed on top of the main frame to be distanced from the detecting rod with a certain interval and detect the detecting bump. The present invention is to provide a blank gripper for a blank transporting robot which detects a blank with no holes formed to prevent a blank having no holes to indicate a standard position from being placed into a mold of a hot-rolled press molding process. |
