Process for automatically feeding work stations and apparatus for practicing the process

摘要

A method of feeding a work station, which utilizes a robot to grasp workpieces one after the other at a charging station to which the workpieces are successively conducted to feed them to the work station and to transfer the workpiece worked upon to a discharging station. The robot grasps every workpiece arriving at the charging station by a workpiece holder that grasps the workpieces at a predetermined place thereon and holds them during all the time of transfer thereof and working thereon and releases the workpieces only when they arrive at the discharging station. At the work station, the workpiece holder is held in a very precise position by a gripping block rigidly fixed to a member in the work station. An apparatus for practicing this method comprises a workpiece holder adapted to the geometry of the workpieces to be processed, and a gripping block mounted on a member in the work station and arranged to receive the workpiece holder and to securely hold the same in a precise position at the work station.PPThis application is a continuation of application Ser.
