Abstract
An automated tool changer system for a drilling or other type of machine tool system. A gripper apparatus transports tools held in a tool magazine to a tool working unit such as a drill spindle. The tool working unit is supported by an upper support beam above a workpiece-supporting table mounted for movement in an X-Y plane. The magazine is supported by a sliding carriage mounted on the upper support beam, and can be moved upwardly and downwardly to insert and remove tools from the gripper apparatus. The gripper apparatus is supported by the X-Y table, and can be raised or lowered relative to the table during the tool changing operation. The gripper apparatus is provided with two possible grip pressures, and with a sensor for detecting the presence of the tool end at a predetermined grip jaw reference point. The sensor permits the tool to be inserted into the spindle chuck with a predetermined length of tool extending from the chuck.
