PURPOSE: To minimize the superposition of each operation area of a robot and an operator and thereby aim at improvements in safety for the operator and operability, by making a robot hand so as to carry in and out a work with an opening part installed in the back and the side of a machine tool.
CONSTITUTION: When machining of a work 1 gets through with a numerically- controlled lathe 10, a rear auto-door 13 and an oil retaining door 16 both open automatically whereby a robot hand 14 of a detachable robot 11 goes to take the work 1 by way of an opening part 15 installed in the back of the NC lathe 10, taking the finished work 1 out of a chuck 6, and mounts it on a takeout table 2. Next, the robot hand 14 regrasps the work blank 1 and conveys it to the inside of the lathe by way of the opening part 15, while the work 1 is attahced to the chuck 6, and when the robot hand 14 retracts to the specified position outside the lathe 10, the oil retaining door 16 and the auto-door 13 close automatically so that the lathe 10 gets machining. Here, in time of automatic operation, a manual door is being closed but in time of manual operation and preparatory procedure, the auto-door and the oil retaining door are closed so that each operation area of the operator and the robot will no longer interfere with each other.
